<p>PURPOSE:To improve the operability by adopting a constitution that an ejecting means is moved up to a midpoint when no cassette is loaded. CONSTITUTION:When a holer 2 pushed down while no cassette 5 is loaded, a switch 7 detects the falling of the holder 2 and a turned on, but a switch 8 is turned off. In such a case, a loading motor 14 is driven forward and a guide or the like is moved by the drive of upper-lower loading rings. Since the switch 8 is turned off in this case, the contact between a contact piece 15c and a contact (c) is disconnected by the turning of a rotary position detector 15, the movement of the guide to the 3rd position is detected by the disconnection between contacts (a, c), a signal from a control circuit 19 stops a loading motor 14, a cassette motor 16 starts being driven forward and a loading part 3 approaches a drum 10. The cassette motor 16 is stopped similarly when a switch 17 is turned on and the title device is stopped entirely.</p> |
