<p>PURPOSE:To automatically eject a cassette by energizing an automatic lock release member through switch operation and using the automatic release member to drive a lock arm in the lock release direction and to provide a reverse torque to a drive gear. CONSTITUTION:A motor is driven counter clockwise upon the receipt of a cassette eject command to shift an S gear 23 and an L gear 21 to a mesh enable position. The gear 23 drives the gear 21 counter clockwise to release the pressing of a cassette 47. This is implemented by a shaft 29 provided to a cassette retainer 3 overriding a projection of a cam 46 provided to the gear 21. When the gear 21 keeps rotation, the shaft 29 is lifted up to raise a cassette 47 via the cassette retainer 3 and a cassette holder 2. Furthermore, the gear 21 keeps rotation, a shaft 22 implanted upright to the gear 21 drives an L slider D 15 thereby ejecting the cassette 47 from the opening.</p> |
