  • Patent number: 11434098
    Abstract: 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.

  • Patent number: 11370633
    Abstract: 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.

  • Patent number: 11163254
    Abstract: 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.

  • Patent number: 10669114
    Abstract: 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.
