Abstract: If a cartridge moves to a complete loading position which is inward of a device by a loading device, a sliding plate moves in Y2 direction in accordance with the loading device. At this moment, because a control convex portion engages a concave portion of a door setting portion by moving from a convex portion of the manipulating member, the manipulating member is pulled by a fourth biasing member and rotates in an ?2 direction. Therefore, a control pin moves inside a manipulating groove and sets a door in a closed position. Also, the door is set in the closed position as well even after the cartridge is drawn out of the device.
