A feeding device to feed a sheet in a feeding direction includes a mount on which a substantially rectangular parallelepiped sheet pack is mountable; a first cutter to cut, in the feeding direction, a first side surface on one end side in a width direction orthogonal to the feeding direction out of four side surfaces of the sheet pack; a second cutter to cut, in the width direction, a second side surface on a downstream side in the feeding direction out of the four side surfaces; and a third cutter to cut, in the feeding direction, a third side surface on another end side in the width direction out of the four side surfaces. Height positions cut by the first cutter, the second cutter, and the third cutter coincide with each other. Cut portions by the first cutter, the second cutter, and the third cutter are coupled to each other.

According to examples, an apparatus may include an input tray coupled to a media path and an output tray to receive media from the media path. The output tray may be automatically positioned to an open position based on the media being inputted into the input tray. A movable section may be movably coupled to the output tray. In some examples, the movable section may automatically move relative to the output tray based on the output tray being automatically positioned to the open position.

A cassette drawing-in device includes a guide portion to guide a pin protruding from a paper feed cassette, a first member in which the guide portion is formed, a second member facing the first member, a first rotation shaft, a first link rotationally supported by the first rotation shaft, a second rotation shaft provided on the first link, a second link rotationally supported by the second rotation shaft and including an engagement groove which engages the pin and slides on the pin in a direction intersecting the moving direction of the pin, and a protruding portion on one or both of the first member and the second member within a range of movement of the second link that accompanies the rotation of the first link about the first rotation shaft.

A sheet feeding apparatus includes a stacking portion, a feed member provided above the stacking portion and configured to feed an uppermost sheet among the sheets stacked on the stacking portion, and a trailing-end regulating member movable in the sheet feeding direction and configured to regulate a position of a trailing end of the sheets stacked on the stacking portion in the sheet feeding direction. The trailing-end regulating member includes a support portion configured to support a lower surface of the sheets stacked on the stacking portion. The support portion has a projecting shape in which a center portion of the support portion in a sheet width direction projects upward as compared with end portions of the support portion in the sheet width direction.

A sheet feeding apparatus includes a supporting portion to support a sheet, a feeding portion to feed the supported sheet, and a base member opposed to the supporting portion so the sheet is supported by the supporting portion between the supporting portion and the base member. A regulation unit includes a regulation portion to regulate a position of an edge portion of the supported sheet and moves in a moving direction, and a sensor outputs an output value that changes in accordance with an amount of movement of the regulation unit. The sensor and the regulation unit are supported by the base member, and the sensor is supported by the base member at a position above an abutment position between the sheet supported by the supporting portion and the feeding portion in a gravity direction.

According to aspects of the present disclosure, there is provided a tray swinging mechanism including a document tray. A movable plate of the document tray is configured to be swingable about a tray shaft and extends leftward. A lifter is configured to be swingable about a lifter shaft extending in the front-rear direction at a position different from the tray shaft. On a lower surface of the movable plate, a cam surface configured to contact a tip of the lifter is formed. The cam surface includes a parallel part parallel to an upper surface of the movable plate and a curved part spaced from the upper surface farther toward a right side. According to a shape of the cam surface, each time the lifter is rotated by a particular angle, the tip of the movable plate moves by a particular amount.

The image forming apparatus includes a side panel and a manual feed tray that is rotatable and installed on the side panel. The side panel includes an opening portion through which a sheet placed on the manual feed tray passes when the sheet is fed into the image forming apparatus. The manual feed tray includes an end cursor that is movable, and a guide portion that guides movement of the end cursor in a direction perpendicular to a rotational center of the manual feed tray. The opening portion is sized to accommodate the end cursor. When the opening/closing angle of the manual feed tray with respect to a horizontal direction exceeds a predetermined angle, the end cursor moves along the guide portion by gravity to a position where the end cursor can be accommodated in the opening portion.

A medium placing device (feeding tray) includes a placement unit, a regulation unit (edge guide), a displacement unit, a detection unit, and an adjustment unit. The regulation unit (edge guide) includes a first regulation member (first edge guide) and a second regulation member (second edge guide). The displacement unit is capable of moving the first regulation member (first edge guide) and the second regulation member (second edge guide) in directions opposite to each other along a first direction. The detection unit is provided between the placement unit and the adjustment unit.

A sheet conveying device includes a sheet placement table, a sheet discharge table, a conveyance mechanism, raising/lowering mechanism, and a raising/lowering control portion. The sheet discharge table is located below the sheet placement table. The conveyance mechanism conveys a sheet placed on the sheet placement table onto the sheet discharge table via an execution position at which image processing is executed by an image processing portion. The raising/lowering mechanism raises and lowers the sheet placement table. The raising/lowering control portion controls the raising/lowering mechanism in accordance with a clearance that is defined by a height from the sheet on the sheet discharge table to the sheet placement table, so as to maintain the clearance to be equal to or higher than a set value.

A sheet conveying device includes a sheet stacker, an air blower, and a guide. The sheet stacker stacks sheets. The air blower blows air to the sheets. The guide faces an uppermost sheet on the sheet stacker. A set height of a contact portion of the guide to contact the uppermost sheet is changeable
