<p>PURPOSE:To suppress the protrusion of a cassette from an insertion opening at an appropriate degree when the cassette is ejected by stopping a cassette holder (CH) by detecting the fact that the CH arrives at a specific position on a moving path, and moving the CH from which the cassette is drawn out to a position to be inserted. CONSTITUTION:When a small cassette (CA) 2 is placed on the CH 4 by pushing it in the direction of arrow head F, a sensor arm 31 is turned in a counterclockwise direction, and a photosensor 33 is set at a light shielding state, and a motor 36 is rotated in the direction of arrow head, and the CA 2 is carried by moving the CH 4 in the direction of arrow head E, simultaneously, sensor arms 20 and 21 are turned in a clockwise direction, then, photosensor 24 and 25 are set at the light shielding states. When the CH 4 is moved in a horizontal direction and lowered vertically, the pin 9 of the CH 4 makes a sensor arm 22 turn in the counterclockwise direction, and a photosensor 26 is set at a non-light shielding state, and the motor 36 is stopped, and the CA 2 is positioned at a loading position. Next, when the CA is ejected, the motor 36 is rotated in a backward direction, and after the CH 4 is vertically raised and moved in the horizontal direction to a cassette insertion opening 38, the motor 36 is stopped.</p> |
