<p>PURPOSE:To hold a cassette excellently in the horizontal state at the loading position with simple constitution by providing a height difference to the relative height of guide slots guiding a drive member of a cassette holder at the horizontal position. CONSTITUTION:The cassette holder 1 is supported by drive levers 2, 3 and follower wide levers 4, 5 constituting an X link mechanism and provided vertically via springs 13a, 13b. The relative height of guide slots 16a, 16b guided by shafts 11a, 11b of the drive levers 2, 3 is set so that the left guide slots 16b is set higher by DELTAh due to any cause, the difference is cancelled by giving a height difference to the said guide slot 16b. Thus, the holder 1 is kept excellently in the horizontal state at the loading position.</p> |
