  • Patent number: 7731177
    Abstract: A sheet supplying device for an imaging apparatus is provided with a sheet tray configured to mount a plurality of sheets in a stacked state. The sheet tray is inclined such that leading ends of the plurality of sheets are lower than trailing ends thereof. Further provided is a feed roller that faces an uppermost sheet of the plurality of sheets mounted on the sheet tray to be press-contacted thereto. The feed roller is driven to rotate to feed the uppermost sheet. Further provided is a sheet guide mechanism having at least one guiding section provided in front of the feed roller. The guiding section is inclined such that the leading ends of the plurality of sheets are moved toward the feed roller by their own weight. The guiding section is configured such that the degree of inclination of the guiding section varies depending on the amount of the plurality of sheets.

  • Patent number: 7700886
    Abstract: A rubber key device is provide with a key top member, multiple rubber keys, a click feel generating mechanism and a load transmitting mechanism. When a depression area of the key top member is depressed by a user, the key top member is rotated to depress a top face of a rubber key via the load transmitting mechanism. The load transmitting mechanism transmits the load caused by the depression of the depression area to the top face of the corresponding rubber key such that the load is transmitted to only a substantially central portion of the top face of the corresponding one of the multiple rubber keys regardless of the depression amount of the depression area.

  • Publication number: 20090316162
    Abstract: A printer can print to paper with a narrow width while maintaining a print format with good legibility without changing the application program and printer driver installed on the host computer. The control method of a printer that prints based on print data 5 sent from a host computer 3 has a step S105 of extracting data attributes contained in the print data 5 and assigning the print data 5 to data segment areas for each data attribute; a step of setting the data segment areas to specific printing areas based on the data attribute; an actual print data generating step (steps S122, S107, S133, S134, S111) of converting the print data 5 assigned to the data segment areas to actual print data according to the data attributes; and a printing step S113 of printing the actual print data in the printing areas.

  • Patent number: 7497432
    Abstract: A sheet supplying device is provided with a separation roller having an outer circumferential surface contacting at least a part of the sheets in a stacked state, and a pad located to face the outer circumferential surface of the separation roller. The sheet supplying device is further provided with a holder that holds the pad and is movable relative to the separation roller, and a pressing mechanism that presses the holder in a direction in which the pad held by the holder approaches the separation roller. The pad contacts a first surface of a sheet being fed by rotation of the separation roller, and the first surface of the sheet is opposite to a second surface of the sheet contacting the outer circumferential surface of the separation roller. The holder has a recessed portion formed on an upstream side of a pressurization point at which the sheet being fed is nipped between the separation roller and the pad. Space is formed by the recessed portion and a surface of the pad facing the holder.

  • Patent number: 7451971
    Abstract: A sheet feed device has a sheet supply tray in which sheets to be fed are stored, a roller mechanism which ejects each printed sheet on to a sheet holding part, and a cover member which is placed between a sheet supply side on which each sheet is fed before printing and a sheet ejection side on which each sheet is fed after printing. In the sheet feed device, each sheet supplied from the sheet supply tray changes its sheet feed direction approximately 180 degrees before being ejected to the sheet holding part. Part of the cover member on the sheet holding part's side is provided with a first projecting part which lets the ejected sheets be held in the sheet holding part while being bent substantially in an S-shape.

  • Patent number: 7309178
    Abstract: An image formation device (facsimile machine, printer, copier, etc.) is provided, which is capable of reducing the amount of ink ribbon rolled up for the removal of slack of the ribbon. When a ribbon roll-up process is started, the operation mode of the image formation device is first set to a ribbon roll-up mode in which a ribbon roll-up spool is driven without driving a platen. The slack of the ribbon is removed by driving the ribbon roll-up spool to roll up the ribbon without driving the platen, which can reduce the amount of ribbon rolled up for the removal of the slack (the amount of ribbon wasted).

  • Patent number: 7227672
    Abstract: In a gear changing device, when a sun gear rotates in a forward direction, a rotating member is rotated in the same direction as the sun gear and planetary gears are pivotally rotated around the sun gear. When the sun gear rotates in a reverse direction, the rotating member stops rotating and allows the planetary gears to rotate on axes thereof to a plurality of predetermined positions on a path of the planetary gear that pivotally rotates. A plurality of transmission gears are provided at a plurality of predetermined positions along the path of the planetary gear pivotally rotating, so as to engage with each of the planetary gears. A plurality of recesses and projections that are recessed and protruded, respectively, in the diametrical direction of the rotating member are alternately formed in an outer periphery of the rotating member. Each of the recesses and projections has a specific width. A sensor switch that detects the recesses and the projections at a predetermined position is provided.
