• a gripping member that is configured to grip a circumferential edge of the plate;
• a moving member that is configured to move the gripping member at least in a horizontal direction;
• and
• a control unit that is configured to:
• control the moving member to move the gripping member in the horizontal direction to the circumferential edge of the plate placed in the container with the lid being open, and then control the gripping member to grip the circumferential edge of the plate;
• control the moving member to remove the plate in the horizontal direction from the container while the circumferential edge of the plate is being gripped by the gripping member;
• control the gripping member to release and guide the plate toward a collecting member that is configured to collect the plate;
• and
• control the gripping member to throw the plate to the collecting member by controlling the gripping member to release the plate while the moving member is moving the gripping member.
