  • Patent number: 9079734
    Abstract: Disclosed is a paper feeding device (71) including: a paper stacking tray (74) that carries thereon stacked sheets of printing paper and moves up/down along a stacking direction of the sheets of printing paper; a paper transport member (e.g., paper transport belts (81)) that sucks and transports a sheet of printing paper from the paper stacking tray (74); a separation fan (88) that generates an air flow separating the printing paper stacked on the paper stacking tray (74); an air sucking fan (84) that generates an air flow sucking a sheet of printing paper stacked on the paper stacking tray (74); and a relay duct (87) that guides air coming out of the air sucking fan (84) to the separation fan (88). The relay duct (87) extends along a straight line from an air outlet (84b) of the air sucking fan (84) to an air inlet (88a) of the separation fan (88).

  • Patent number: 8950747
    Abstract: A recording paper conveying device includes a registration roller pair and a conveyor roller pair adjacent to the registration roller pair. By rotating the conveyor roller pair, a sheet of recording paper is fed until leading edge of the sheet abuts the registration roller pair in stationary state so that the sheet is deflected by a prescribed amount. Then, conveyor roller pair is rotated at the constant velocity, and while the sheet is kept deflected, rotation of the registration roller pair is started, to start feeding of the sheet by the registration roller pair. While the registration roller pair is kept rotating, rotation of the conveyor roller pair is suspended, and then, the conveyor roller pair is returned to the state of rotation before suspension. Thus, unnecessary deflection of the sheet just in front of the registration roller pair can be prevented.

  • Patent number: 8870179
    Abstract: A paper feed device includes a paper stacking shelf, a paper trailing edge guide that regulates a position of a paper bundle, a contact member that is disposed on the paper trailing edge guide, and a position switch portion that moves the contact member to either a withdrawn away position or a contact position with respect to an upper face of the paper bundle. The position switch portion is provided with a rod that is moved in conjunction with an operation for causing the paper feed device to be pulled out from and pushed into the accommodation space, and a rotatable member that is rotated in conjunction with the movement of the rod. The position switch portion supports the contact member, and causes the contact member to be rotationally moved to either the withdrawn away position or the contact position in conjunction with the rotation of the rotatable member.

  • Patent number: 8439353
    Abstract: A sheet feeding device according to this invention includes a bearing support member and a lever member. The bearing support member is supported in the sheet feeding device for movement between a sheet feeding position and a separated position. The lever member is pivotally movable about a bearing portion between a first position which causes the bearing support member to be positioned in the sheet feeding position while causing the bearing portion to be supported by the bearing support member, a second position which causes the bearing support member to be positioned in the separated position while causing the bearing portion to be supported by the bearing support member and a third position which causes the bearing support member to be positioned in the separated position while allowing the bearing portion to be detached from the bearing support member.

  • Patent number: 7686296
    Abstract: A sheet stacking device includes: an evacuation section for transporting and ejecting sheets; a sheet exit tray for stacking the ejected sheets; an arm supporting member; and a sheet presser arm including a supported end at one end, a free end at the other end which is capable of pressing the sheets stacked on the sheet exit tray directly or via a contact member attached to the free end, and a flexure portion having flexibility between the supported end and the free end. The supported end is attached to the arm supporting member. The arm can apply, by the flexibility of the flexure portion, a pressing force to the sheets stacked on the sheet exit tray and a repulsive force to each of the ejected sheets when a front end of the ejected sheet strikes against the arm.
