The driving source includes a driving shaft. The gate includes a gate shaft, and a blade that is provided on the gate shaft, and switches conveyance routes of paper sheets. The first gear is provided on the gate shaft. The internal gear meshes with the first gear. According to rotation of the driving shaft, the gate shaft rotates on an axis of the gate shaft, and revolves with the driving shaft as a rotation center while the first gear meshes with the internal gear.

A pusher plate stacking bin apparatus is provided for a valuable media depository. The apparatus comprising a pusher plate driven by a rack and pinion apparatus to stack a media item that is in a final position within the apparatus onto a media stacking platform. The media item is urged into the final position such that a trailing edge of the media item overhangs and rests on a fixed media guide and such that a leading edge of the media item overhangs and rests on a hinged media guide with a bottom surface of the media item elevated above the media stacking platform. The rack and pinion apparatus drives the plate past the media guides causing the hinged media guide to drop and the media item to fold along the leading edge as the media item is stacked onto the platform.

A thick document conveying device includes a paper pickup mechanism. The paper pickup mechanism has a pick roller base, a pick roller axle, a pick roller, a switching assembly, a first universal coupling, a driving mechanism, a second universal coupling, a bearing and a gear. The pick roller axle and the pick roller are located in the pick roller base. The switching assembly is located under the pick roller base. The first universal coupling is connected to the pick roller axle. The driving mechanism is sleeved on the first universal coupling. The second universal coupling is connected to the driving mechanism. The bearing is connected to the driving mechanism. The gear is connected to the bearing. As described above, both a thick document and a thin document can be adapted.

A system for presenting media sheets includes a finisher output bin assembly. The finisher output bin assembly includes a translatable output floor, and a guide substrate coupled to the translatable output floor to guide the translatable output floor relative to the guide substrate in at least one coordinate direction. The finisher output bin assembly includes an output structure mechanically coupled to the translatable output floor to drive the translatable output floor relative to the guide substrate.

A medium conveyance device includes a first loading base that has a first loading surface formed thereon and is movably supported on a main body, a second loading base that has a second loading surface formed thereon and is movably supported on the first loading base so that the second loading surface is positioned next to with the first loading surface and so that the second loading surface overlaps with the first loading surface, a mechanism that converts motion of the first loading base into motion of the second loading base so that the second loading base is arranged in a position corresponding to a position in which the first loading base is arranged, and an elastic member that is elastically deformed when the second loading base is not arranged in a position corresponding to a position in which the first loading base is arranged.

A sensor unit includes an edge detection sensor, a sensor carriage, a unit housing, and a carriage moving mechanism. The edge detection sensor is arranged in a conveying portion for conveying a sheet and senses edge positions at both sides in a sheet width direction perpendicular to a sheet conveying direction. The sensor carriage has a carriage main body in which the edge detection sensor is incorporated, and is reciprocatably supported on the unit housing in the sheet width direction. The carriage moving mechanism makes the sensor carriage reciprocate in the sheet width direction. The sensor carriage is selectively positioned at a first position where it makes contact with a first side face at one end side of the unit housing in the sheet width direction or a second position where it makes contact with a second side face at the other end side in the sheet width direction.

A post-processing apparatus includes a tray receiving an ejected recording medium, a moving mechanism vertically moving the tray, a driving source driving the moving mechanism, a member pressing, from vertically above, a recording medium ejected to the tray, a rotational-driving mechanism driving the member so that the member rotates in a first direction away from an apparatus body when the tray is moved upward by the moving mechanism and that the member rotates in a second direction toward the apparatus body when the tray is moved downward by the moving mechanism, a rotation-angle limiting unit limiting a rotation angle of the member when the member is driven to rotate in the first direction and to rotate in the second direction, and a rotational-force limiting mechanism idling when a rotational force not lower than a predetermined force is applied to the rotational-driving mechanism.

A textile feed for a stepped operation digital textile printer, comprises a textile feeding mechanism, and a tension storage mechanism. The textile feeding mechanism feeds the textile in a forward direction onto the printer, but is at the same time mechanically connected to a tension storage mechanism which is tensioned by the forward feeding. At the end of the feed step, the tension storage mechanism releases respectively stored tension to cause the feed mechanism to briefly reverse feed, thereby to pull the textile taut and take up any slack caused by the feeding step. The textile is thus kept taut, to allow effective digital printing by the printer.

A sheet feeding apparatus includes a damper mechanism having a movable portion supported by a sheet storage portion and movable with respect to the sheet storage portion by abutting against a body in a case where the sheet storage portion is inserted to the body, and a resistance member. In addition, a first transmission portion actuates the resistance member to produce a resistive force and transmits the resistive force so that an insertion speed of the sheet storage portion is reduced when the sheet storage portion is inserted to the body, and a second transmission actuates the resistance member to produce the resistive force and transmits the resistive force so that a lowering speed of the sheet supporting member is reduced when the sheet storage portion with the sheet supporting member having been lifted by a lift portion is drawn out of the body.
