<p>PURPOSE:To surely release a cassette cover without generating double lock even when a finger is separated from a push-button in a moment by providing a protrusive piece at an eject lever turned by interlocking with the push-button, and extruding the cassette cover with the protrusive piece compulsorily. CONSTITUTION:When the button part 2b of the eject lever 2 provided at the mounting shaft 1a of a cabinet 1 in such a way that it can be turned freely is pressed with the lock lever pressing part 4a of a push-button part 2, the eject lever 2 is turned, and raises the lock lever 3 with a lock lever pressing part 2a, and the lock lever 3 comes off the lock piece 5a of the cassette cover 5, thereby, lock is released. When the push-button 4 is pressed in further, the eject lever 2 is further turned, and the protrusive piece 2c of the eject lever 2 extrudes the cassette cover 5 compulsorily, therefore, the lock piece 5a of the cassette cover 5 is moved leftward, and the lock lever 3 rides on the upper part of the lock piece 5a, and no engagement occurs even when the finger is separated from the push-button 4. In such a way, since the double lock can be blocked even when the finger is separated from the push-button 4 in a moment, the cassette cover 5 is surely opened.</p> |
