  • Publication number: 20230406010
    Abstract: A sheet processing apparatus to process a sheet includes a first conveyance path, a punching unit, a storage unit, a movement unit, and a receiving unit. The punching unit punches the sheet conveyed in the first conveyance path. The storage unit is removable from the sheet processing apparatus and stores punch chips generated by the punching unit. The movement unit moves together with the punching unit in a direction parallel to a movement direction of the punching unit. The receiving unit is between the movement unit and the storage unit and receives the punch chips from the punching unit via the movement unit while supporting the movement unit. When the storage unit is removed in a state in which punch chips stored in the storage unit have accumulated to reach the receiving unit, some of the punch chips that have reached the receiving unit are leveled by the receiving unit.
