A stand-alone inspection apparatus inspects documents printed on a cut sheet, and includes: a sheet feeder capable of setting the documents in a sorted state; a sorting detector that detects the sorted state of the documents; an image reader that reads an image of the documents; an inspection part that inspects the documents on the basis of the read image; and a sheet ejector that ejects the inspected documents, wherein in a case where the documents in the sorted state are set in the sheet feeder, the sheet ejector ejects the documents in a state equivalent to the sorted state detected by the sorting detector.

An image forming system includes an image forming unit, an inspection unit, a conveyance unit configured to convey a sheet to the inspection unit, a controller configured to execute a first inspection mode in which a sheet having an image formed thereon is conveyed by the conveyance unit to the inspection unit and is inspected, and a second inspection mode in which, without executing image forming by the image forming unit, a sheet is conveyed by the conveyance unit to the inspection unit and is inspected, and a setting unit configured to set a recovery process. The setting unit permits the setting of the recovery process in the first inspection mode and prohibits the setting of the recovery process in the second inspection mode.

A sheet feeding apparatus for feeding sheets is provided with a multi feed detecting section for detecting multi feed of conveyed sheets in a predetermined detection position of a conveyance path, and first and second discharge sections to which multi-fed sheets with the multi feed detected are discharged, and corresponding to one of a front end position of the multi-fed sheets at the time the multi feed detecting section detects the multi feed of sheets, a sheet storage state of the second discharge section, sheet storage states of the first and second discharge sections, a size of sheets and weighing, selects one of the first and second discharge sections to discharge the multi-fed sheets to the selected discharge section.

A medium conveyance route switching device includes a support unit, a gate assembly, and a rotation mechanism. The support unit is located at a branching point of a first conveyance path, a second conveyance path and a third conveyance path where conveyance directions of a medium converge in three directions. The gate assembly includes a first to a third gate positioned on one ends of the first to the third conveyance path to guide at the branching point the medium to other conveyance paths than a conveyance path from which the medium is conveyed. The rotation mechanism includes a first actuator rotating the first gate to switch the medium conveyed from the first conveyance path to the second conveyance path or the third conveyance path, and a second actuator, when the first gate is rotated, rotating the second gate and the third gate in associated with the second gate.
