<p>PURPOSE:To provide sufficiently elevating force to a holder by providing an oil damper to the rear side of a cassette holder along the cassette inserting direction, and connecting the holder and the damper via an arm at one point of the holder where the movement is decreased when the holder is moved to the vicinity of the uppermost position to decrease the buffer effect of the damper near the uppermost position. CONSTITUTION:When a lock is released by depressing a cassette eject button is depressed, a resistance force is given counter clockwise to a rotary disc in a damper 13 by means of the oil sealed in a rotary damper 13 to buffer the upward movement of the cassette holder 3. Then, a pin 5a of an arm 9 is moved downward right along a long hole 5 from the vicinity of the middle of the long hole 5, an open side for cassette loading of the cassette holder 3 is lifted up, and the entire cassette holder 3 is turned clockwise around a pin 17. In this state, since the rotary shaft of the rotary damper 13 is hardly turned, the resistance force of the damper 13 is not exerted to the entire turning of the said cassette holder 3 and sufficient elevating force is provided.</p> |
