  • Patent number: 7946776
    Abstract: A sheet feeding procedure supplies recording media from a medium enclosing portion to a medium conveying path. An overlap-feed detecting procedure monitors a thickness of recording media supplied to the medium conveying path, thereby detecting the overlap-feed media. Sheet returning procedures (A) and (B) return the overlap-feed media into the medium enclosing portion when the overlap-feed media are detected. A looseness forming procedure applies rotational forces of different rotation speeds to upper and lower surfaces of the overlap-feed media during the medium returning procedure, thereby forming a looseness in the overlap-feed media. A medium re-feeding procedure supplies again the returned recording media to the medium conveying path from the medium enclosing portion. In the medium feed control, the overlap-feed can be further certainly recovered.

    Abstract: A printer is equipped with a supply roller for sending a piece of sheet from pieces of sheets stacked within a cassette; a pair of feed-in rollers for sending the piece of sheet supplied from the supply roller toward a printing region; and a sheet sensor provided between the supply roller and the pair of feed-in roller. The printer rotates the pair of feed-in rollers in a forward direction in a case that the sheet sensor detects presence of the sheet at a timing when it is found that printing data for a subsequent sheet is not stored within the printer. On the other hand, the printer rotates the supply roller in a reward direction when the sheet sensor detects non-presence of the sheet at the timing when it is found that the printing data for the subsequent sheet is not stored within the printer.

  • Patent number: 7570914
    Abstract: An image forming apparatus feeds a paper picked up by a pickup roller directly to a photoconductive drum and controls a linear velocity of the pickup roller so that it is slower than that of the photoconductive drum. The different linear velocities of the pickup roller and the photoconductive drum produces different velocities at the transfer nip (the area of contact between the photoconductive drum and a transferring roller) and the point where paper is picked up by the pickup roller. To compensate for the different velocities, the pickup roller can be rotated faster than the photoconductive drum for an angle that corresponds to the velocity difference. Additionally, when a velocity difference occurs between two rollers for feeding the paper, one of the rollers can be further rotated to compensate for the velocity difference.

  • Patent number: 7540676
    Abstract: A manual sheet feeding mechanism adapted for use in a sheet processing apparatus includes a manual feeding tray and a guiding member. The manual feeding tray is adapted to be mounted on a side wall of the apparatus so as to be pivotable about an axis between an open position and a closed position. The manual feeding tray has a placement surface for placing a sheet to be manually fed into the apparatus. The guiding member is adapted to position a sheet placed on the placement surface and is provided so as to be movable on the placement surface. The manual sheet feeding mechanism also includes a moving member that is adapted, when the manual feeding tray is pivoted toward the closed position, to move the guiding member on the placement surface.

  • Patent number: 7520688
    Abstract: A mounting arrangement and/or stand for supporting a print feed mechanism relative to a printer. The mounting arrangement includes first and second support members defining first and second mating surfaces, respectively. The first support member is adapted to support the print feed mechanism and the second support member is adapted to support the first support member. Furthermore, the first and second mating surfaces define a mating interface or plane which is inclined relative to a horizontal plane. The relative position of the first and second support members is maintained by a means for coupling the first and second segments along the inclined mating plane. The coupling means is, furthermore, operative to selectively position the first support member relative to the second support member so as to separate the print feed mechanism segment from the printer by a fixed separation distance.

  • Patent number: 7473043
    Abstract: A card supplying mechanism includes a card stacker with a motor-driven rotatable eccentric cam for sequentially raising and lowering a moving member having an oblique, step-shaped card touching surface. A motor rotates the cam to a position of maximum diameter, thereby lifting vertically-stacked cards with the oblique, step-shaped card touching surface. The motor then drives further to rotate the cam to a position of minimum diameter, thereby separating one end of the cards on an oblique card support surface so as to mutually offset stacked cards. A kick roller then discharges from the stacker a bottommost stacked card. The card supplying mechanism provides a reliable supply of cards by virtue of both improved card separation, and reduced load on the bottommost card that is to be supplied.
