Printer With A Cutter Having A Pushing Portion For Moving The Fixed Blade Away From The Movable Blade - Patent 8152394
1. Field of the Invention The present invention relates to a printer with a cutter capable of appropriately cutting a recording sheet after printing on the recording sheet pulled out from a paper roll. 2. Description of the Related Art Nowadays, a great number of various types of thermal printers, which performs printing by pressing a heated thermal head against a special recording sheet that changes color when heat is applied thereto, are provided. In particular, use issuitably made in printing of various labels, receipts, tickets, and the like because smooth character printing and colorful graphic printing are possible without using toner, ink, and the like. As represented by the thermal printers, numerous printers with a cutter provided with a cutter mechanism for cutting the printed recording sheet are known. The cutter mechanism is normally set (auto cutter) to automatically cut the recordingsheet when printing is terminated, and hence the cut recording sheet can be immediately used for a receipt, a ticket, and the like, as mentioned above. The printer with a cutter is used by being incorporated in, for example, a cash register, a mobile terminal device, and the like. The cutter mechanism is typically configured by a fixed blade and a movable blade that is slidable. When cutting the recording sheet, the movable blade is slid so as to ride on the upper surface of the fixed blade. Both the blades thensandwich and cut the recording sheet as if a pair of scissors. The fixed blade is configured to have the root side supported by a hinge portion, and the cutting edge side to be swingable, and is biased to be pushed upward by a biasing portion such as a coil spring. Thus, when the movable blade slides, boththe blades are brought into contact with each other at an appropriate contacting pressure. As a result, the recording sheet can be cut neatly. However, the fixed blade and the movable blade often bite each other due to the jam of the recording sheet when cu
Printer Device With Blade Driving Motor And Platen Motor Provided On A First Frame - Patent 8152393
1. Field of the Invention The present invention is related to a printer device, and particularly, to a printer device having a cutter function and a thermal head. 2. Description of the Related Art Small-size thermal printers are installed in POS terminals and ticketing terminals. In order to facilitate setting of paper, a thermal printer includes a first module and a second module which is detachably attached to the first module, and acutter device is provided with the first module joined to the second module. The cutter device includes a plate-like fixed blade, which is fixed to the first module, and a plate-like movable blade, which is slidably attached to the second module; themovable blade moves to cross the fixed blade to cut the paper like scissors. For example, Japanese Laid-Open Patent Application No. 2005-059395 (referred to as "reference 1" hereinafter) discloses a technique in this field. The POS terminals and the ticketing terminals use roll paper as printing media. The roll paper used in the POS terminal or the ticketing terminal is 70 .mu.m in thickness, and the cutter device described above can sufficiently cut such kind ofpaper. Presently, for example, when making labels, sometimes, thermosensitive paper thicker than 150 .mu.m is used. When the thickness of the paper is thicker than 150 .mu.m, the load imposed on the cutter device when cutting the paper becomes large. For example, considering the plate-like movable blade, since the movable blade is relatively flexible, such a large load may shorten the service-life of the movable blade. Further, when the thickness of the paper is thicker than 150 .mu.m, the paper is more elastic, so that it is required that the channel for conveying the paper induces small resistance against movement of the paper.SUMMARY OF THE INVENTION The object of the present invention is to solve one or more problems of the related art. According to a first aspect of the present invention, there is provided a printer devi
One-row Keyboard And Approximate Typing - Patent 8147154
BACKGROUND It is fascinating to reflect on the great impact of the PC on society. The PC is clearly capable of doing a whole lot more than what we use it for. Essentially, for many the PC became a replacement for the typewriter, and it is still largely aword processor. The other initial application that drove PC adoption was the spreadsheet. Then it also became a presentation creation tool. Over time, email was introduced and, even more recently, Web browsing. Web browsing, in turn, is giving riseto online shopping and replacing encyclopedias as our primary information resource. But, overall, there are still very few uses for these powerful machines by the average user. We are now going through a phase where the capabilities of different types of devices are converging. Devices rely on common protocols and are often connected via the Internet, and the services offered are becoming more portable and accessiblewherever we are and whenever we need them. We now have PCs, cellphones, TVs, iPods, PDAs, and camera phones relying on the Internet, complemented by communication networks such as the cellular networks, Bluetooth, and Wi-Fi. Services range from unifiedmessaging and VOIP to entertainment. With these trends toward greater connectedness and mobility, perhaps the most central problem is how to make text entry possible on small, portable devices. The success of email, SMS, and instant messaging on portable devices and user patternsalready established on the PC make an efficient text-entry system a must for broad adoption of smaller, mobile devices. In this direction, the RIM pagers (the Blackberry devices) are prime examples of a well-designed portable device. It is simply an excellent email machine, and for many this immediate access to email becomes highly addictive. A great deal ofthe success of this type of device relies on its small keyboard, which allows for two-thumb typing. This typing is quick and easy to learn since it relies on the same basic
Tag Making And Stacking Systems And Method, Tag Stackers And Stack Trays - Patent 8147156
BACKGROUND 1. Field The field to tag making and stacking systems and method, tag stackers, and stack trays. 2. Brief Description of the Prior Art The following U.S. patent documents are made of record: U.S. Pat. Nos. 5,092,697; 7,125,182; U.S. patent application Ser. No. 11/409,803; and Printer Systems Revised Slitter Operation Instructions Manual, Cover page and pages ii and 1:1through 1:6.SUMMARY An embodiment relates to an improved stacking system for a printer and to trays for stacks of tags. As the printer operates, tags can accumulate in a removable tray in the stacker. When the desired number of tags has accumulated in the tray,the printer can be stopped or interrupted and the tray can be removed. An empty tray can be inserted into the stacker and the printer can resume printing. In the meantime, the tray containing the accumulated stack of tags can be taken to a locationwhere the tags are to be used, and so on. It is clear that by use of one or more trays the overall output of the printer can be increased. An embodiment of a method of handling tags, comprises providing at least first and second removable trays insertable and positionable in a tag stacker, inserting the first tray in the tag stacker, feeding tags into the first tray in the tagstacker, interrupting the feeding of tags, removing the first tray from the tag stacker, inserting and positioning the second tray in the tag stacker, and feeding tags into the second tray in the tag stacker. The method can start out by providing a rollof a printable web, printing on the web on one or both sides of the web, and severing the web into separate tags. Alternatively, printed tags can be provided in the form of a roll of a tag web and the tags can be severed from the tag web. An embodiment of the disclosure includes a stacking system comprising a stacker having a platform, a tray removably supported on the stacker, the tray including an upstanding rear panel and a bottom panel connected to the r
Recording Apparatus - Patent 8147157
1. Field of the Invention The present invention relates to a recording apparatus that forms an image on a recording sheet on the basis of image information. 2. Description of the Related Art A recording apparatus is used as an output device for a computer or an output device for a digital image. In addition, a recording apparatus is also used for a photocopier, a scanner, a complex machine of these, or a system. The recordingapparatuses can be classified according to recording method into categories, for example, a thermal transfer type, an ink jet type, a laser beam type, and a wire dot type. In addition, the recording apparatuses can also be classified into either aserial type or a line type. The serial type uses both the main scanning by a recording head and the sub-scanning by paper feeding. The line type uses a line recording head and performs recording using only the sub-scanning. In a thermal transferrecording apparatus, an ink sheet is pressed against a recording sheet and heated so as to transfer ink, and image recording is thereby performed. Particularly in a line type thermal transfer recording apparatus, a plurality of heating elements arrangedin the width direction of a recording sheet are selectively driven, the recording sheet and an ink sheet are conveyed in the sub-scanning direction, and dot-line-like images are thereby sequentially recorded. Recently, with the advancement of image input devices such as a digital camera, a digital camcorder, and a scanner, a thermal transfer recording apparatus has gotten a lot of attention. A thermal transfer recording apparatus is a recordingapparatus suitable for printing out electronic image information picked up with a still camera or a camcorder, through a computer or a memory medium. In other types of recording apparatuses such as an ink jet recording apparatus, there is only a binarychoice between to form a dot or not. Therefore, small dots are formed on a recording sheet and for example, error
Roll Paper Printer With Positioning Members - Patent 8147155
BACKGROUND 1. Field of Invention The present invention relates to a roll paper printer that prints on a paper web delivered from a roll of paper held freely rotatably inside a roll paper compartment, and relates more particularly to technology for preventing problems caused bythe leading end portion of the roll paper unwinding in the transportation direction inside the roll paper compartment and then shifting sideways. 2. Description of Related Art Roll paper printers print to a paper web that is pulled from a roll of paper held freely rotatably inside a roll paper compartment. Due to the inertia of the paper roll when the paper is pulled from the roll, the portion of paper that is woundat the outside circumference of the roll may unwind and be left in a slack loop inside the roll paper compartment. When the side walls of the roll paper compartment are simple flat guide surfaces (roll paper guides) located a specific distance apart, the unwound portion at the outside circumference side of the paper roll may shift widthwise and become angledto the normal transportation direction. Even when the side walls of the roll paper compartment are rendered using a plurality of guide surfaces instead of by simple flat guide surfaces, the slack unwound portion at the outside circumference of the paperroll may shift widthwise and become angled to the normal-transportation direction. This can cause such problems as the edges of the roll paper catching on the edge of the guide surface or the edges being folded over as the paper is delivered from theroll paper compartment. To avoid such problems when the sides of the roll paper compartment are defined by a plurality of roll paper guides, the distance between the left and right roll paper guides disposed along the direction in which the roll paper rotates (that is,disposed substantially parallel to the direction in which the roll paper is conveyed) gradually narrows from the upstream side to the downstream side in the direction
Print Medium Cartridge Which Has An Elastic Partition Member Which Increases The Capacity Of A Cut Piece Collection Portion - Patent 8142088
1. Field of the Invention The present invention relates to a cartridge that contains print medium or ink sheets, and to a printing apparatus whose cartridge is detachable and that prints images onto print medium or the like. 2. Description of the Related Art Conventional printing apparatuses used as output apparatuses for printing images from personal computers (PCs), digital cameras, and the like are classified into thermal printing apparatuses, inkjet printing apparatuses, laser printingapparatuses, dot matrix printing apparatuses, and so on depending on the recording technique. In particular, thermal printers utilize ink sheets and print sheets, selectively energizing multiple heating elements arrayed in the main-scanning directionand conveying the inks sheets and print sheets in the sub-scanning direction, thereby printing onto the print sheets. Due to the recent progress in devices that handle images, such as digital cameras, digital video cameras, scanners, and so on, servingas input apparatuses, thermal printers are garnering more and more attention. Two types of thermal printers have gone into production. One has a configuration in which print sheets cut out at a set size are laminated (stacked) and are supplied in such a form, and the other has a configuration that supplies a continuousprint sheet wound into a roll and cuts the print sheet to an appropriate size after printing. Although the size is large with the configuration that cuts the roll-type print sheet, a large amount of print sheets can be supplied at once, which provides an advantage in that running costs can be significantly reduced. A thermal printer uses metallic rollers called capstan rollers (or grip rollers) to convey the paper with high precision, which prevents the colors yellow, magenta, and cyan from becoming misaligned when those colors are overlapped andtransferred. However, a paper conveyance mechanism that uses capstan rollers has a disadvantage in that a region that cannot
Printing Device With Paper Width Detector Mounted To Carriage And Method Of Controlling The Printing Device - Patent 8142087
Priority is claimed under 35 U.S.C. .sctn.119 to Japanese Patent Application No. 2007-092525, which is herein incorporated by reference in its entirety.BACKGROUND 1. Technical Field The present invention relates to an image printing device and a method of controlling the image printing device. 2. Related Art Generally, image printing devices having a paper feeding tray that loads a plurality of paper sheets to be overlapped with one another and a print mechanism that performs a printing process for a paper sheet fed and transported from the paperfeeding tray one by one have been known. As an image printing device of this type, for example, as disclosed in JP-A- 5-24321, an image printing device that determines paper jam or the degree of duplicate transport by calculating the length of a papersheet for which a printing process has been completed based on a time when the paper sheet for which the printing process has been completed passes a paper discharge detecting sensor and comparing the result of calculation with data relating to thelength of the paper sheet that has been stored in a memory in advance has been proposed. It has been described that the efforts and time to cope with jam and duplicate transport can be reduced and a time for creating a document can be shortenedaccording to the above-described image printing device. The occurrence of duplicate transport can be generally classified by the type of discrepancy in the overlapping orientation of the printing media. Hereinafter, a duplicate transport with a vertical discrepancy refers to when at least oneprinting medium is not completely overlapping a first printing medium along the transport direction; a duplicate transport with a horizontal discrepancy refers to when at least one printing medium is not completely overlapping a first printing mediumalong the main scanning direction. However, although the above-described image printing device can determine whether duplicate transport with a vertical d
Image Forming Apparatus And Sheet Containing Apparatus - Patent 8142089
1. Field of the Invention The present invention relates to an image forming apparatus, and in particular to an image forming apparatus in which a protecting member is detachably attached to an inside of the apparatus main body to protect a protected member in theapparatus main body when the image forming apparatus is transported. 2. Description of the Related Art An image forming apparatus such as a conventional copier, a printer, or a facsimile machine, is detachably attached with a protecting member inside of the apparatus main body so as to prevent the displacement, deformation, and other damages ofthe members in the apparatus main body due to vibration during transportation when the image forming apparatus is packed and shipped. On the other hand, during transportation, for example, a process cartridge, which can be attached to and removed from the image forming apparatus main body, is transported separately from the image forming apparatus. In the process cartridge, aphotosensitive drum, which is a protected member, is protected during transportation by an openable and closable shutter unit, which is a protecting member. This process cartridge includes a sealing unit for preventing the leakage of the developer before use. The sealing unit closes the shutter unit during transportation. In other words, during transportation, the sealing unit as a fixing unitfixes the shutter unit into a state in which the photosensitive drum is protected by the shutter unit. When mounting the process cartridge in the image forming apparatus main body, a user removes the sealing unit, and thereby the shutter unit can be opened and closed. In this state, the process cartridge can be mounted to the image formingapparatus main body. However, when the user fails to remove the sealing unit, since the shutter unit cannot be opened or closed, the process cartridge cannot be mounted to the image forming apparatus main body. This means that the process cartridge cannot be mounted t
Selectively Coupling A Device To A Carriage - Patent 8137017
The present invention relates generally to selectively coupling a device, such as an optical measurement device, to a carriage, such as a printer carriage while moving past an intervening mechanism, such as an activator for a cutting tool.BACKGROUND OF THE INVENTION Referring to FIG. 1, one example of a wide format ink jet printer 10 includes right and left side housings 72, 74, and is supported by a pair of legs 76. The right housing 72, shown in FIG. 1 with a display and keypad for operator input andcontrol, encloses various electrical and mechanical components related to the operation of the printer 10. The left housing 74 encloses ink reservoirs 86 which feed ink to the ink-jet printheads 82 via plastic conduits 84, which run between each ink-jetprinthead 82 and each ink reservoir 86. In some printer embodiments, no separate ink reservoirs 86 or tubing 84 is provided, and printing is performed with ink reservoirs integral to the printheads. Housing 72 or 74 may also include a maintenancestation to clean and cap the printheads as needed. A printing region extends all or part of the way between the two housings 72 and 74. Either a roll of continuous print media (not shown) is mounted to a roller on the rear of the printer 10 to enable a continuous supply of paper to be provided to the printer 10 or individual sheets of paper (not shown) are fed into the printer10. In the case of roll-fed media, the media is cut after printing an image. A platen 78 forms a horizontal surface which supports the print media, and printing is performed by selective deposition of ink droplets onto the paper. During operation, acontinuous supply of paper is guided from the roll of paper mounted to the rear of the printer 10 across the platen 78 by a plurality of rollers (not shown) which are spaced along the platen 78. Print carriage 12 is supported above the platen 78 by primary guide rail 70. The print carriage 12 includes a plurality of ink-jet printheads 82 mounted therein.
Image Forming Method For Determining A Position Of An Ink Ribbon With A Boundary Line - Patent 8137015
1. Field of the Invention The present invention relates to an image forming device. More specifically, the present invention relates to thermal printer and image forming method that use an ink ribbon mechanism. 2. Background Information In recent years, efforts are being made to develop image forming devices for printing print data (YMC data), which are obtained by converting and expanding image data (RGB data) from transmitted from a digital video camera. Since this kind ofYMC data are structured as gradation data, it is preferable to use an image forming device that has high gradation reproducibility. Therefore, development of thermal transfer type image forming devices (thermal printers and the like) is being pursuedbecause the gradation reproducibility of thermal transfer type image forming device is considered to be better than that of ink discharging-type image forming device. With thermal transfer image forming devices (e.g., thermal printers), a large number of gradations can be obtained per pixel by controlling the amount of heat to be applied during printing. Thermal printers are normally provided with a thermalhead (line head) having several thousand or more heating elements (dot heating elements) arranged in a row (arranged along the main scanning direction). The thermal head is configured to transfer the dye (ink) of the ink ribbon to a transfer sheet (print sheet) by heating the ink ribbon. Since the amount of ink transferred to the print sheet varies depending on the amount of heat transferred bythe thermal head, this variation is utilized to form an image having rich gradations on the print sheet. A known image forming device is configured such that when a print driver receives a print instruction from a computer, a thermal printer application, or the like, the print driver sends a warm-up start instruction to a control unit (CPU) of theimage forming device. Upon receiving the warm-up start instruction, the control unit sends a control signa
Tensioning Print Media - Patent 8137016
BACKGROUND Printers such as inkjet printers which print onto a variety of print media such as paper or film are well known. As well as accepting print media in a single sheet format, some printers also accept print media fed from a supply roll of printmedia, in other words a web of print media. Such a printer may be typically referred to as a web printer, being a printer that accepts a web of print media. Paper, vinyl, textiles, fabrics, and others are examples of print media. Relative movement between the print media and the print head enables print media coverage and image creation. A majority of billboards and banners having relatively large dimensions are printed on flexible print media. Such print mediarepresent rolls or webs of flexible material that are up to five meters wide. The feeding of a web of print media from a roll for a large format printer is typically undertaken by means of rollers, some of which induce the media movement and others change the media direction or form nips enabling media transportation. Inthe context of the present disclosure the term "nip" means the gap or width of the gap between two parallel rollers. The nip may have a desired width or the rollers may be in contact having a nip width equal to zero. The print media is pulled from a roll that has a mechanism to provide tension (back-tension) in the media so as to reduce undulations or wrinkles in the media. In the context of the present application the term "back tension" means the forcethat keeps the substrate tensioned with respect to a drive roller. A difference in rotational speed between two or more rollers typically generates the back tension. Despite this back tension, undulations or wrinkles are sometimes formed before a nipand close to a location of one of the rollers, usually a tensioning roller. Small undulations are sometimes pulled into the nip between different rollers and reach a printing zone or region of the printer, degrading the quality of printed ima
Duplex Printing Apparatus - Patent 8137014
The present invention relates to a duplex printing apparatus, and more particularly to a duplex printing apparatus for performing a duplex printing operation.BACKGROUND OF THE INVENTION With rapid development of electronic industries, a diversity of printing apparatuses such as copiers, printers, scanners or multifunction peripherals become essential information apparatuses in offices. Among these printing apparatuses, theprinters are the most popular. In the early stage, a printer can perform a single-side printing operation. For performing duplex printing operations by such a printer, a first page of a document file shown on a computer screen is firstly printed on afirst side of a blank paper. After the first page of a document file has been printed, the paper containing the printed image of the first page should be manually turned over and then placed on the paper input tray of the printer. Next, a second pageof the document file is printed on a second side of the paper. However, the process of manually turning over the paper is troublesome. This drawback becomes more serious if the document contains a great number of pages. Recently, a duplex printingapparatus has been developed for automatically performing a duplex printing operation. FIG. 1 is a schematic cross-sectional view illustrating inner components of a conventional duplex printing apparatus. As shown in FIG. 1, the conventional duplex printing apparatus 100 principally comprises a paper input tray 101, a paperejecting tray 102, a paper pick-up roller 106, a paper feeding channel 105, a first paper transfer roller assembly 109, a scanning and developing print unit 103, a print region 104, a paper ejecting channel 107, a heating roller 1038, a pressing roller1039, an inverting channel 108, a paper guide slice 113, a second paper transfer roller assembly 110, a third paper transfer roller assembly 111, a fourth paper transfer roller assembly 114 and a paper ejecting roller assembly 112. The sca

Field of the Invention The present invention relates to an image generating apparatus, and more particularly, it relates to an image generating apparatus comprising a heat radiating member radiating heat generated in a print portion. 2. Description of the Background Art An image generating apparatus comprising a heat radiating member radiating heat generated in a print portion is known in general, as disclosed in each of Japanese Patent No. 3005916, Japanese Patent Laying-Open No. 9-188027 (1997), JapaneseUtility Model Registration No. 2607240 and Japanese Patent Laying-Open No. 2001-322304. The aforementioned Japanese Patent No. 3005916 discloses a thermosensitive recording apparatus (image generating apparatus) comprising a radiator plate (heat radiating member) mounted on a thermal head (print portion), a platen roller, apressing member pressing a rear surface of the radiator plate so as to bring the thermal head into pressure contact with the platen roller, and a pressure releasing lever having a cam shaped portion separating the thermal head from the platen roller. Inthe thermosensitive recording apparatus described in Japanese Patent No. 3005916, the cam shaped portion of the pressure releasing lever rotates about the platen roller functioning as an axis of rotation so that the thermal head in pressure contact withthe platen roller is pressed in a direction opposite to a pressure contact direction with the cam shaped portion presses and the thermal head is separated from the platen roller. No rotating shaft is provided on the radiator plate mounted on the thermalhead. The aforementioned Japanese Patent Laying-Open No. 9-188027 discloses a thermal transfer printer (image generating apparatus) comprising a radiator fin (heat radiating member) mounted on a thermal head (print portion), a platen roller, and ahead arm rotatable in a direction in which the thermal head is brought into pressure contact with or separated from the platen roller. In the thermal
Reduced Impact Keyboard With Cushioned Keys - Patent 8132976
BACKGROUND Overuse of computer keyboards can cause discomfort in the fingers of users. During a typical keystroke on a keyboard of a computing device, the key bottoms out against a solid surface after actuating a key switch. This can cause a force spikeduring deceleration of the key. Since the duration of deceleration is short, the deceleration forces may be several times higher than the acceleration forces encountered at the beginning of the keystroke. High force can cause discomfort to the user, which can negatively impact the user experience, and potentially reduce productivity. In addition, high force is one of the main risk factors for musculoskeletal pain and disorders. Further, highimpulse loads may be damaging to the soft tissues of the body. Finally, when the key is bottomed out, the user's finger may be pressing eccentrically (i.e., the joint is moving away from direction in which muscle force is being applied) or isometrically(i.e., force with no movement) against the key, which can be a damaging type of loading.SUMMARY A keyboard for use with a computing device and a method of manufacturing a keyboard key are provided. One disclosed keyboard includes a plurality of keys, each key having a key cap including a perimeter wall and a void positioned within theperimeter wall and opening to a top of the key cap. Each key further includes a cushion having a top portion configured to be contacted by a digit of a user and a bottom portion configured to be fitted within the void in the key cap. The cushion beingmay be configured to absorb an impact force directed against the key during a keystroke. This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subjectmatter, nor is it intended to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subjec
