<p>PURPOSE: To prevent malfunction by utilizing the operation of an eject lever and operating a holding means holding a head plate at the unplaying position by a cam piece provided on the eject lever. CONSTITUTION: When the cassette P is inserted from the unplaying position, a cassette holder is lowered, in the case it is fully inserted, and the locked state of the eject lever 13 is released by this descent and retreated in the direction of this side by a spring 14. Then, a working piece 6 is pressurized by the cam piece 16, and a locking stepped part 7 and a locking piece 11 are disengaged, thereby the head plate 3 is moved in the playing direction by a spring 4. When the eject lever 13 is pressurized against the spring 14 from this state, the arc surface of the cam piece 16 is brought into contact with a rotary unit 15, then the head plate 3 is pushed and moved in the unplaying direction.</p> |
