<p>PURPOSE:To contrive a long stroke of a cassette holder and to enable accurate positioning of the holder by moving the holder with a slant guide of a slider along an L-shaped guide to a loading position. CONSTITUTION:The cassette holder 7 selectively inserted by a large or small cassette 1 or 2 is drawn horizontally in the direction of an arrow (b) along a 1st guide part 81 of the L-shaped guide 8a by the slider 10 to be driven by one pair of timing belts 12. Subsequently, when guide rollers 9a-9c are entered into a 2nd guide part of the L-shaped guide, the holder 7 is lowered vertically and loaded by its weight and the guiding operation of the slant guide 15. In this case, right and left guide rollers 16 are entered underneath the horizontal lower end of the slant guide 15. Consequently, a long stroke can easily be attained for the operating stroke of the cassette holder 7, and also cassette pressing force can be secured without needing a lock mechanism.</p> |
