<p>PURPOSE:To put loading devices in smooth motion with simple constitution by placing the loading devices in the reciprocal motion along a couple of guide rails by a slide plate which is moved reciprocally by a motor through a couple of expansible link mechanisms. CONSTITUTION:After a cassette is loaded, the loading devices 16 and 17 and a pinch roller 20 are moved forward from the backward movement positions to forward movement positions in the cassette 9 as shown by arrows (a) and (b). For example, the couple of loading devices 16 and 17 are guided between the forward and backward movement positions along the couple of guide rails 34 and 35. Then the slide plate 32 is driven by the motor 22 arranged below the cassette 9. This slide plate 32 is driven to put the loading devices 16 and 17 in the reciprocal motion through the couple of expansible link mechanisms 44 and 45 along the couple of guide rails 34 and 35.</p> |
