<p>PURPOSE:To simplify a cassette loading drive mechanism and to attain a cost down, by providing an idler having a contact with either a cassette loading mechanism or a tape loading mechanism and sharing a driving source. CONSTITUTION:The 1st and the 2nd rotary levers 15 and 16 are supported in a body and coaxially with the 2nd worm wheel 13, and an idler gear 18 is supported by a support shaft 17 of a lever 15. The gear 18 engages a driving gear 14 and can touch either one of the 1st and the 2nd driving gears 7 and 9. Now if a cassette is loaded, a motor 10 revolves forward and the gear 18 revolves counterclockwise. Then the gear 18 engages with the gear 7 to load a holder 1 since the revolutions of the lever 16 are controlled by a projection 21a of an up-down lever 21. In this case, the control of the projection 21a is released, and the gear 18 engages with the gear 9 to load a tape. Thus the motor 10 is shared to simplify the driving mechanism.</p> |
