<p>PURPOSE:To almost vertically move and mount a cassette while the cassette keeps a horizontal position by causing a supporting shaft, which is in the back of a cassette holder, to fall down with the turn of an auxiliary holder and causing the front direction of the cassette holder to simultaneously fall down with the operation of a cam roller, which is fit to a guide channel, at an almost same speed as the supporting shaft. CONSTITUTION:A supporting shaft 12b for cassette holder is arranged in the tip part of a turning arm 12 to be supported by a supporting shaft 12a, which is provided in the front direction of a base stand 2, with being freely turnable. Then, a cam roller 13 is arranged in an internal part to be interlocked with an auxiliary holder 11. In the central part of a cassette holder 4 which is supported by the supporting shaft 12b, a cam roller 14 is samely provided so as to be interlocked with the auxiliary holder 11. To the auxiliary holder 11 which is supported by a supporting shaft 3a in the back of the base stand 2 with being freely turnable, the two cam rollers 13 and 14 are fit and the turning arm 12 and cassette holder 4 are moved with being interlocked. Then, two guide channels 11b and 11c are provided so that the cassette holder 4 can keep the horizontal position. Thus, while the cassette keeps the horizontal position, the cassette can be moved and mounted almost vertically.</p> |
