<p>PURPOSE:To reduce the load of the motor of a driving mechanism by providing a cassette extruding arm, a large cassette engagement part and an arm operating member, extruding only a small cassette and preventing a large cassette from being extruded. CONSTITUTION:When the small cassette 6 is inserted in a cassette holder 4, the tip part of the cassette 6 is engaged with a small cassette engagement part 12 and the cassette extruding arm 14 is turned by a prescribed angle (theta1). When the cassette 6 is moved further, the arm is turned further and a part to be operated 16 gets over the arm operating member 17. Then, the cassette is loaded on a spindle. When an instruction showing the finish of reproducing is given, the arm 14 is turned in an extruding direction and the cassette 6 is extruded from the holder 4 by a prescribed quantity. When the large cassette 7 is inserted in the holder 4, it is engaged with the large cassette engagement part and the arm 14 is turned by a turning angle (theta2). Then, the part to be operated 16 is made to approach the side surface of the holder 16. Since the part to be operated 16 is passed without being engaged with the member 17, the cassette 7 is not extruded by the arm 14.</p> |
