<p>PURPOSE:To eliminate disturbance of a disposing member on a side plat or in its vicinity by the operation of an arm member for pressing a front cover lock releasing pin by bringing the position of an operation unit of the member into coincidence with the height of a groove of the side plate during the horizontal stroke of conveying a cassette. CONSTITUTION:An arm member operating unit 3b at a cassette discharging position is brought into contact with a side plate 1 to become a state that a front cover lock releasing pin 4a provided at a cassette 4 is not pressed. Since an arm member operating unit 3b is brought into contact with the vertical height of the groove 1a of the plate 1 during the horizontal stroke of conveying the cassette 4, the unit 3b is released to the groove 1a to become a state that the pin 4a of the cassette 4 is pressed. Thus, the arm member 3 can be operated without disturbing the member disposed on the plate 1 or in its vicinity.</p> |
