<p>PURPOSE:To eliminate the inconvenience involved in the latching, by locking a latch type plunger solenoid to a non-latch position when a tape cassette is not loaded and then releasing the locking of the solenoid when the loading of the tape cassette is detected. CONSTITUTION:While a tape cassette 4 is not loaded ket to a recorder/reproducer and carried, a slide plate 11 is moved toward an arrow X1 and then locked by a lock bar 20 to receive the limit for shift toward X2. Thus it is impossible for a plunger 10a and the plate 11 to move toward X2. Therefore a latch type plunger solenoid 10 is kept under a non-latch state despite application of a big impact to eliminate the inconvenience in which an injection button cannot be pushed. When the cassette 4 is loaded, the bottom surface of the cassette 4 presses the top 25a of a detecting pin 25. Then the pin 25 presses down the bar 20, and an arm part 20c comes out of a notch 11d. As a result, the locking of the plate 11 is released. Thus the plate 11 moves toward X2. Then reel desks 2 and 3 are released from a damping state respectively.</p> |
