<p>PURPOSE:To accurately control the position of a cassette holder by a cam plate provided only on one side by setting the movement stroke on the follow-up side of the cassette holder to a value longer than that on the driving side. CONSTITUTION:A supporting shaft 4 of a guide arm 2 provided on the side face of the right follow-up side of a cassette insertion hole 1c is so set that it is placed above a supporting shaft 3 on the driving side where a cam plate 5 is arranged. Consequently, the vertical movement stroke of a cassette holder 1 and the shake stroke of a guide arm 2 are longer than those on the driving side, and the upward over stroke and the downward movement stroke are cancelled in the rise position of the cassette holder, and the cassette holder 1 is kept horizontal.</p> |
