A post-processing apparatus includes an ejection tray receiving a recording medium that is ejected, an elastic member urging the ejection tray upward in a vertical direction, a moving mechanism causing the ejection tray to move up and down in the vertical direction, and a driving source driving the moving mechanism.

Post-processing apparatus and image forming apparatus

An image forming apparatus includes a housing in which an image forming unit is to be mounted, a support that supports an image reading device in a state where the image reading device is separated from the housing, and a guiding portion in which a guide part, which is formed on a to-be-mounted surface of an add-on device in such a manner as to project, is to be inserted such that the guide part is guided by the guiding portion. Engagement holes with which engagement portions, which are formed on the to-be-mounted surface of the add-on device in such a manner as to project, are to be engaged such that the engagement portions are positioned by the engagement holes are formed in a mounting surface of the housing on which the add-on device is to be mounted.

Image forming apparatus in which add-on device is mounted

A sheet transport device includes first to third rotating members, a sheet position detector, and a controller. The first member transports a sheet at a first speed. The second member transports the sheet at a second speed that is lower than the first speed. The third member in a stopped state receives the sheet and subsequently resumes transporting to perform positional correction thereon. The detector detects positions of leading and trailing edges of the sheet. The controller performs control such that, when a preset time elapses after the detector detects that the leading edge has reached the third member, the third member is caused to resume transporting at the second speed, and when the detector detects that the leading edge has passed the second member, the third member is increased in speed from the second speed to the first speed.

Sheet transport device and image forming system

An image reader includes a cabinet and an optical system. The cabinet has four plate members fixed to each other by laser welding from a side direction of the image reader and has a bottom wall fixed to the four plate members by laser welding from a side direction or a lower direction of the image reader. The cabinet has a first opening for a document read window opening toward an upper direction of the image reader. Each of the plate members is bended in letter L shape to form an upper end part and a side wall. The optical system is housed in the cabinet for reading an image of a document through the opening.
