A sheet sorting apparatus comprising a first tray, a second tray, a conveyance unit, a tray detection unit, a stacking amount detection unit, and a control unit configured to control the conveyance unit to not convey the sheet to the second tray, in a case where the stacking amount detection unit detects that the amount of sheets reaches the predetermined amount, wherein the control unit is configured to permit the conveyance unit to convey the sheet to the second tray, in a case where the tray detection unit detects that the first tray is detached from the apparatus main body in a state where the stacking amount detection unit detects that the amount of sheets reaches the predetermined amount and conveyance of the sheet to the second tray by the conveyance unit is stopped.

Sheet sorting apparatus

A sheet sorting apparatus includes a second tray arranged below a first tray detachable from a main body having a first discharge port corresponding to the first tray and a second discharge port corresponding to the second tray, a discharge unit, a tray detecting unit, and a control unit. The discharge unit discharges a sheet toward the first or second discharge port. In a state that the first tray is detached from the main body and the discharge unit discharges sheets from the first discharge port to the second tray and then the first tray is detected as attached to the main body, the control unit selects a discharge destination of a second sheet, subsequent to a first sheet discharged and stacked first after the first tray is attached to the main body, such that the second sheet is stacked on a tray having the first sheet thereon.

Sheet sorting apparatus and image forming apparatus

A sheet sorting device includes three or more trays including a predetermined tray detachable from an apparatus main body and a tray different from the predetermined tray, a discharge unit to discharge a sheet to any one of the three or more trays, a control unit, and a tray detection unit to detect that the predetermined tray is detached from the apparatus main body. The control unit sets a sheet discharge destination such that a sheet conforming to a preset condition is discharged to the predetermined tray through the discharge unit. Where the tray detection unit detects that the predetermined tray is detached from the apparatus main body, the control unit sets a sheet discharge destination that has been set to the predetermined tray to the tray different from the predetermined tray based on a state of each of the trays other than the detached predetermined tray.

Sheet sorting device and image forming apparatus

A sheet sorting apparatus includes a first tray detachable from an apparatus main body, a second tray arranged below the first tray, a discharge unit to discharge a sheet to the first or second tray, a tray detecting unit to detect that the first tray is detached from the apparatus main body, a full stack detecting unit to detect a fully stacked condition of the first tray, and a control unit to control the discharge unit. In a case where the tray detecting unit detects that the first tray is detached from the apparatus main body, the control unit controls the discharge unit not to discharge a sheet to the second tray when a number of sheets discharged to the second tray reaches a threshold number of sheets, even though the full stack detecting unit does not detect the fully stacked condition.

An image forming system includes a processing tray, a detecting unit, a stapling unit, a discharge tray, an instruction unit, and a control unit. Recording material, placed on the processing tray, is detected by the detecting unit. When instructed, the stapling unit can staple the detected recording material. Stapled recording material then is discharged to the discharge tray. The control unit controls switching between a first mode wherein a stapling process is executed and a second mode where the stapling unit executes the stapling process after the detecting unit detects recording material inserted into the processing tray and the execution instruction are received. If an instruction to interrupt a power supply of the image forming system is received in the second mode, the control unit causes recording material inserted into the processing tray to discharge to the discharge tray and then interrupts the power supply without the stapling process executing.

Image forming system for executing stapling process

A recording material processing apparatus includes: a first stacking unit configured to stack a recording material; a second stacking unit provided on a downstream side of the first stacking unit in a conveyance direction of the recording material; an alignment unit configured to align the recording material stacked in the first stacking unit before the recording material is discharged to the second stacking unit; and a control unit configured to perform control of discharging the recording material to the second stacking unit by switching between first control not to align the recording material by the alignment unit and second control to align the recording material by the alignment unit.

Recording material processing apparatus including alignment unit for aligning recording materials and image forming apparatus

A sheet conveyance apparatus includes: a guide member configured to guide a sheet in a first direction in a first state, and in a second direction in a second state; a driving source configured to generate a driving force; a transfer member configured to change the state of the guide member from the first state to the second state by being moved by the driving force; and a control unit configured to control the driving force. The control unit is further configured to set the driving force to a value smaller than a force necessary to move the transfer member to change the guide member from the first state to the second state, and subsequently cause the driving force to increase to a value larger than the force necessary to move the transfer member.
