An image reading apparatus includes a main body, a touch panel, a document transport path, a feed tray, a feed roller, a separation unit, a reader, a discharge roller, a discharge tray, and a mounting table. The mounting table is provided on an upper side of the main body and includes an upper surface. The mounting table is located at an outer face of the main body, the upper surface serves as a mounting surface on which the source document to be fed or the source document that has been read is mounted. The mounting surface is located at a position higher than an upstream end of the feed tray when the source document is mounted on the mounting surface.

A conveying device includes a rotating carrier, an inlet rotary body, an outlet rotary body, a downstream conveyor, and an inching controller. The rotating carrier carries a sheet. The inlet rotary body transfers the sheet to the rotary carrier from upstream of the rotary carrier in a conveyance direction of the sheet. The outlet rotary body transfers the sheet to a downstream area from the rotary carrier in the conveyance direction. The downstream conveyor conveys the sheet downstream from the outlet rotary body in the conveyance direction. The inching controller performs an inching operation to convey the sheet on a conveyance path including at least the downstream conveyor. The inching controller causes at least the outlet rotary body and the downstream conveyor to perform a conveying operation in conjunction with each other in the inching operation.

A sheet conveyance device capable of reducing occurrence of creases on a sheet. A pair of first conveyance rollers nip and convey a sheet. A pair of second conveyance rollers arranged downstream of the first conveyance rollers in a sheet conveyance direction nip and convey the sheet. A pair of registration rollers arranged downstream of the second conveyance rollers nip and convey the sheet after correcting skew of the sheet. A switching mechanism switches a state of the second conveyance rollers between a contact state and a separated state. A control unit that controls the rollers and the switching mechanism executes a first conveyance operation that conveys the sheet with the first conveyance rollers and the registration rollers after correcting the skew in the separated state and in a state where a sheet conveyance speed by the registration rollers is higher than that by the first conveyance rollers.

A medium conveying apparatus includes a feed roller, a brake roller, a motor to generate a driving force, a first transmission mechanism to transmit the driving force to the brake roller through a first torque limiter, to rotate the brake roller in a direction opposite to a medium feeding direction, a second transmission mechanism to transmit the driving force to the brake roller through a second torque limiter, bypassing the first torque limiter, to rotate the brake roller in the direction opposite to the medium feeding direction, and a processor to detect media multi-feed, and perform control in such a way as to transmit the driving force to the brake roller by the second transmission mechanism and also cause the feed roller to be driven to rotate in the direction opposite to the medium feeding direction by the brake roller, when the media multi-feed is detected.

An image forming system includes a detection unit to detect a recording material, having an image formed thereon by an image forming unit, placed on a processing tray, a staple unit, a discharge unit, and a discharge tray. A first mode of the system is to discharge the recording material conveyed from the image forming unit to the discharge tray via the processing tray and a second mode involves waiting for instruction for executing. When the detection unit detects the recording material inserted into the processing tray in the second mode, and a recording material first mode conveying instruction is issued in a state of waiting for the executing instruction after the recording material detection, a discharge operation is performed to discharge the recording material inserted into the processing tray to the discharge tray without the staple unit executing staple processing on the recording material inserted into the processing tray.

A sheet feeding apparatus includes a first detection device that outputs a first signal upon detecting a stacked sheet and outputs a second signal upon detecting no sheet, and a second detection device that outputs a third signal when a sheet stacking member is above a predetermined position and outputs a fourth signal in a case where the stacking member is below the predetermined position A control unit controls movement of sheet stacking member by restricting movement of the stacking member when the second signal is output and the third signal is output when power of the sheet feeding apparatus is turned on. The second detection device includes a switch that emits the third signal while abutting a moving member that moves with the sheet stacking member and emits the fourth signal while being separated from the moving member.

A feeding device comprises a suction feeding unit having a belt for feeding a sheet in a suction state and a belt driving unit, a sheet detection sensor, and a control unit. The control unit controls the belt drive unit so as to feed the sheet in a feeding direction at a first speed. If the sheet does not arrive at the sheet detection sensor, the control unit controls the belt drive unit so as to execute a low-speed feeding of moving the belt in the feeding direction at a second speed lower than the first speed or so as to execute a reverse feeding of moving the belt in a reverse feeding direction opposite to the feeding direction.
