An opening/closing pin 36 to open/close to shutter 32 is mounted on one end part of the opening/closing lever 34, and the opening/closing lever 34 is pressed in the direction of the arrow C by a spring 37. To control the rotation of opening/closing lever 34 in the direction of the arrow C, a part 49 of an arm 39 sucking and ejecting the cassette 31 is abutted on an abutting pin 43 erected on another end part of the opening/closing lever 34.
