Provided is a paper feeding device for a printer that is capable of absorbing an impact occurring when a rear end of paper escapes from the outer peripheral surface of a pickup roller and thus comes into contact with a bottom surface of a paper stacking part. The paper feeding device for a printer includes: a paper stacking part for stackedly accommodating at least one or more sheets of paper therein; a pickup roller protruding from a bottom surface of the paper stacking part to feed the paper forward; and buffers linearly protruding from the bottom surface of the paper stacking part to absorb the impact occurring when the rear end of the paper escapes from the outer peripheral surface of the pickup roller and then comes into contact with the bottom surface of the paper stacking part.

A reloading supply system includes a loading cart (100) and a machine (200). The loading cart has a first material tray (120) that includes a first combed surface (122) configured to retain a supply material in the first material tray. The machine has a second material tray (220) that includes a second combed surface (222) configured to retain the supply material in the second material tray after the supply material is transferred from the first material tray of the loading cart to the second material tray of the machine. Teeth (124) of the first combed surface are configured to pass by teeth (224) of the second combed surface. The first combed surface and the second combed surface are configured such that the supply material in the first material tray is transferred to the second material tray as the teeth of the first combed surface pass by the teeth of the second combed surface.

The present invention includes a lift portion lifting and inverting a sheet group including a plurality of stacked sheets and a conveyor portion that moves, along a conveying direction, each sheet transferred from the lift portion, wherein: the lift portion includes frames, a fork portion, an inversion mechanism turning the fork portion to lift and invert the sheet group, and a fork movement mechanism moving the fork portion; the lift portion is equipped with a width direction movement mechanism moving the sheet group in a width direction; and after the sheet group is mounted on the fork portion and before the sheet group is transferred to the conveyor portion, the width direction movement mechanism is controlled on the basis of detection information from a position sensor to center the sheet group within a reference width direction range.

A sheet separating apparatus of the present invention includes a main body portion including a placement face on which a plurality of layered sheets are placed, a convex portion that is protruded from the placement face and on which ends of the sheets are placed, and a magnetic circuit arranged at the main body portion. The magnetic circuit includes a plurality of permanent magnets aligned arranged in line in X direction along the placement face with the same poles of adjacent permanent magnets being faced to each other, first yokes each arranged between the permanent magnets, nonmagnetic members each arranged between the permanent magnets and the sheets, and second yokes each arranged between the nonmagnetic members.

A manual paper feeding portion includes a medium placing portion on which paper to be fed is placed, a guide portion that is provided on the medium placing portion, guides a side edge of the paper in a width direction intersecting with a feeding direction, and is movable in the width direction, and a positioning mechanism that determines a position of the guide portion in the width direction, in which the positioning mechanism regulates the position of the guide portion by positioning portions arranged with a predetermined interval in a first region of a moving region of the guide portion and regulates the position of the guide portion in a stepless manner in a second region which is a region other than the first region.

A sheet stacking apparatus is provided. A stacking unit on which a sheet bundle is to be stacked. A lifting unit can lift up and down the stacking unit. An air blower unit can apply air to a side face of the sheet bundle via an air blowing port. The stacking unit further includes a stacking face that comes into contact with and holds a lowermost sheet of the sheet bundle, and a support portion that supports a portion of the stacking face near an end portion thereof, and has a face that is not parallel to the stacking face. The support portion includes a ventilating portion that allows air blown out by the air blower unit from a portion of the air blowing port, the portion being below the stacking face, to pass through the ventilating portion.

A sheet material feeding apparatus includes: a cassette configured to internally contain a sheet material; a push-up plate that is mounted on an inner bottom surface of the cassette and that is a plate on top surface of which the sheet material is mounted; a push-up plate displacement mechanism configured to include push-up plate biasing members and to change a posture of the push-up plate using a biasing force of one of the push-up plate biasing members; a width regulating member configured to be displaced in a width direction intersecting with a feeding direction and to regulate a position of the sheet material; and a biasing member selecting mechanism that includes a switching unit configured to switch application and release-application of the biasing force of one of the push-up plate biasing members to a posture change of the push-up plate, in interlocking with displacement of the width regulating member.

Disclosed is a drawing apparatus including: a base member; and a drawing member that is attached so as to be capable of being drawn and pressed in a reciprocating direction with respect to the base member, wherein the base member has a couple application mechanism that applies a couple for correcting skewing of the drawing member with respect to the reciprocating direction to the drawing member as a reaction of a force by which the drawing member is pressed, and wherein the couple application mechanism is configured so that a distance between action lines of two forces generating the couple becomes large as a pressing amount of the drawing member with respect to the base member increases.

An apparatus includes a housing provided with a conveyance path, a conveyance unit which conveys a sheet along the conveyance path, a discharge port from which the sheet conveyed along the conveyance path is discharged, a discharge tray on which the sheet discharged from the discharge port is stacked, and an attitude change unit which changes an attitude of the discharge tray. The discharge tray includes a first sheet receiving surface which is a portion facing the discharge port in a discharge direction of the sheet and on which a leading edge of the sheet lands, and a second sheet receiving surface which is formed at a predetermined inclination with respect to the first sheet receiving surface. The attitude change unit changes the attitude of the discharge tray so that the first sheet receiving surface of the discharge tray is inclined toward the discharge port.

Provided is an image-forming device with which it is possible to achieve a smaller size while suppressing a reduction in visibility or operability of an operation panel. In this image-forming device, paper sheets are discharged from the rear side of the device toward the front side of the device, and the image formation device is provided with: a paper-sheet-loading unit in which the paper sheets are loaded; an operation panel disposed on the downstream-side end in the paper sheet discharge direction of the paper-sheet-loading unit, at least a part of the operation panel being disposed in a loading region of the paper-sheet-loading unit; and a protruding part disposed to the side of the operation panel in the loading region, the protruding part protruding upward from the top surface of the paper-sheet-loading unit, and extending in the paper sheet discharge direction.
