A sheet feed device comprises a main body section, a support section, a first link, a second link, an engagement mechanism, an energization section and a correcting section. The correcting section is movable in an approaching position at which the support section approaches the main body section against energization force of the energization section while being contactable with the second link in a direction in which the first link moves to a downstream side in the conveyance direction, and is movable in a separation position at which the support section is separated from the main body section while being separable from the second link in a direction in which the first link moves to an upstream side in the conveyance direction.

Provided is a paper feeding roll that prevents paper transportation failures over a long time. A paper feeding roll 10 is provided with an axial body 12 and an elastic layer 14 formed on an outer periphery of the axial body 12. The circumferential surface of the elastic layer 14 has a plurality of projections 16 forming surface unevenness. Each projection 16 of the plurality of projections 16 is shaped such that a position X of a distal-end part preceding in an opposite direction to a paper feeding direction precedes, in the opposite direction to the paper feeding direction, a position Y of a base-end part preceding in the opposite direction to the paper feeding direction.

A sheet processing apparatus according to an embodiment includes a first tray that holds a sheet transported to the sheet processing apparatus in a sheet transport direction. A second tray is provided below the first tray and holds the sheet moved from the first tray. A first member, when the sheet is moved from the first tray to the second tray, rotates about a turning shaft, and presses a first portion of the sheet toward the second tray by making a pressing portion of the first member contact with the first portion. A second member, when the sheet is moved from the first tray to the second tray, protrudes toward the second tray at a position between the turning shaft and the pressing portion of the first member, and presses a second portion of the sheet toward the second tray, the second portion being located downstream of the first portion.

An image forming apparatus includes plural medium transport paths that branch at a predetermined branching position and along which a medium is transported in a curved state; a switching member disposed at the branching position and including a guide surface that allows the medium to be transported along one of the medium transport paths, the switching member switching between the medium transport paths; an output unit that outputs the medium toward a stacking portion, on which the medium is to be stacked, while corrugating the medium; and a guide portion that guides the medium from the branching position toward the output unit in a region in which the medium is corrugated.

A stack of media items are urged along a transport path that includes a bend in the track of the transport path. A first phase of separating the media items from the stack includes pre-separating the media items from the stack as the media items are urged along the bend. A second phase includes separating a leading media item from the stack by urging the leading media item exiting the first phase between opposing rollers to transport the leading media item along the transport path within a value media depository.

A feeding device is disclosed, which comprises a paper passage, a sheet-separating roller, a friction institution, and a stopper. The sheet-separating roller is disposed in the paper passage. The friction institution is disposed in the paper passage opposite to the sheet-separating roller. The stopper is disposed in the upstream side of the sheet-separating roller. The stopper includes an axle, a short arm, and a long arm. The short arm connects to the axle, and the axle acts as a fulcrum. The long arm and the short arm disposed to the axle coaxially. A threshold of the force for pushing the short arm is larger than a threshold of the force for pushing the long arm.
