<p>PURPOSE:To make handing operation easy by previously separating a full-proof lever unnecessary for the detection of a miserasing preventing claw of a cassette half out of horizontal rotation type full-proof levers from the cassette half and operating a stopping member in a stopping state. CONSTITUTION:Since the shaft 5c of an operation lever 5 in its forward movement stopping state is always pressed against the cam face 4a of a cam gear 4 by the energizing force of the spring 17, the shaft 5c is moved in the right direction. An abutting chip 5d of the operation lever 5 is abutted upon an abutting chip 6e of a full-proof connection lever 6 to move the lever 6 in the right direction. Since the full-proof 2 is connected with a connection pin 6d of the lever 6, the full-proof 2 is rotated in the counterclockwise direction and a claw detecting pin 2b is separated from the cassette half 25. When the left side miserasing preventing claw of the cassette half 25 is not broken, the full-proof 1 is rotated in the counterclockwise direction by the energizing force of a spring 16 until the claw detecting pin 1c of the full-proof 1 is abutted upon the cassette half, and at that time, an REC preventing part 1a is not opposed to the bent part 7c of an REC lever 7, so that the lever 7 can be operated.</p> |
