A sheet transport apparatus includes a first casing in which a transport path is formed; a transport unit which transports a sheet along the transport path; a second casing which is provided to be movable with respect to the first casing; a sheet support unit which is rotatably provided in the first casing at a position on a side to which the second casing is moved, the sheet support unit being changeable between a first state, a second state, and a third state and supporting the sheet at least in the third state; and an urging unit which urges the sheet support unit toward the first state within a range from the first state to the second state and which urges the sheet support unit toward the third state within a range from the second state to the third state.

A spring mounting structure includes a first structural member and a second structural member. The first structural member includes: a first abutting surface to abut on one end of a compression spring; and a temporary holding portion to temporarily hold the compression spring in an uncompressed state. The second structural member includes: a second abutting surface to abut on another end of the compression spring; and a tapered surface to, when the second structural member is assembled in a predetermined assembling direction intersecting a compression direction of the compression spring, guide the other end of the compression spring in the uncompressed state temporarily held by the temporary holding portion to the second abutting surface such that the compression spring is mounted in a compressed state between the first and second abutting surfaces.

In an image forming apparatus to which a finisher is connected, a power source control unit shifts the image forming apparatus to a power saving state. The image forming apparatus is inhibited from being shifted to the power saving state when it is detected that a sheet for which a binding process is to be performed is set in the finisher. The image forming apparatus may be permitted to be shifted to the power saving state when it is not detected that the sheet is set in the finisher.

A sheet feeding device includes a side face of a device body and a bypass tray. The bypass tray is supported turnably around a fulcrum part in the side face between a close position along the side face and an open position held at a predetermined angle with the side face. The bypass tray includes a locked piece having a locked hole. The side face includes a locking hook engaging with the locked piece when the bypass tray is at the close position. The locking hook includes an elastically deformable arm part, an engaging protrusion part protruded inwardly from a distal end of the arm part in a width direction of a sheet to insert into the locked hole, and a regulating part coming into contact with an opening edge of the locked hole to regulate an insertion amount of the engaging protrusion part to the locked hole.

An image processing apparatus comprises a container which is constituted by a bottom connected with a side wall of the image processing apparatus and extending upwards in the vertical direction at a predetermined angle from the side wall and a side wall section vertically arranged on the bottom, and houses a sheet to be processed in a space formed by the side wall of the image processing apparatus and the side wall section; and a pickup section configured to make a roller enter to the inside of the container when the pickup section executes a pickup operation for conveying the sheet to be processed to a main body section of the image processing apparatus and make the roller located inside the image processing apparatus when the pickup section does not execute the pickup operation.

A paper feeding unit of an image forming apparatus according to an exemplary embodiment is provided with a base portion, a guide, a protruding portion, and a roller. The base portion is capable of having the sheet placed thereon. The guide erects with respect to the base portion. The guide regulates a position of the sheet in a width direction which intersects with a transporting direction of the sheet. The protruding portion is provided on the guide. The protruding portion faces an end portion of the sheet in the width direction from a side opposite to the base portion. The roller is provided on the protruding portion. The roller is provided with a circumferential surface facing the end portion of the sheet. The roller is rotatable in the transporting direction of the medium.

An image forming apparatus is provided that forms an image on a sheet material based on a sheet material setting relating to the sheet material. The image forming apparatus includes an accepting unit configured to accept a selection of a sheet material type, a thickness measurement unit configured to measure a thickness of the sheet material, and a setting determination unit configured to determine the sheet material setting that relates to the thickness of the sheet material based on the sheet material type accepted by the accepting unit and the thickness of the sheet material measured by the thickness measurement unit.

A pressing apparatus configured to generate a force in a separating direction in which a first unit and a second unit being connected to each other are separated from each other, the pressing apparatus including: a pressing portion supported by the second unit to be turnable about a turn shaft and configured to press the first unit; and an urging portion configured to urge the pressing portion in a direction intersecting with the separating direction, wherein the pressing portion exerts the force on the first unit in the separating direction by an urging force of the urging portion in the direction intersecting with the separating direction.

An image processing apparatus comprises a container mounted on a side wall of the image processing apparatus and comprising a bottom extending upwards in the vertical direction at a predetermined angle from the side wall for supporting an end of a sheet and a wall member vertically arranged on the bottom and forming a space with the bottom, and configured to house a sheet in the space through an opening formed on the upper side of the container; and a pickup unit located adjacent to the bottom of the container and having a pickup roller and configured to move the pickup roller to the inside of the container if a pickup operation for conveying the sheet to the inside of the image processing apparatus is executed, and keep the pickup roller at a waiting position outside of the space of the container if the pickup operation is not executed.

A sheet transport apparatus includes a first casing in which a transport path is formed; a transport unit which transports a sheet along the transport path; a second casing which is provided to be movable with respect to the first casing; a sheet support unit which is rotatably provided in the first casing at a position on a side to which the second casing is moved, the sheet support unit being changeable between a first state, a second state, and a third state and supporting the sheet at least in the third state; and an urging unit which urges the sheet support unit toward the first state within a range from the first state to the second state and which urges the sheet support unit toward the third state within a range from the second state to the third state.
