<p>PURPOSE:To perform both tape loading and cassette loading actions just with a single motor 1 by transmitting with free switching the revolving power of the center gear driven by a motor to its both adjacent gears. CONSTITUTION:The revolving power given from a motor 11 is transmitted to a clutch middle gear 13 via a motor gear 12, and a projected part 14 engages a projected part 23 of a clutch upper gear 21. While a non-engagement state is secured between a projected part 15 and a projected part 24 of a clutch lower gear 22. Therefore only the gear 21 revolves and therefore a spur gear 30 engaging the gear 21 also revolves. Then a worm wheel 32 at the cassette loading side revolves via a worm 31. Thus a cassette is loaded. Then a change level 19 is turned counterclockwise and therefore the gear 13 moves down via a change pin 18. Thus the parts 15 and 24 engages with each other, and the engagement is released between the parts 14 and 23. As a result, the revolving power given from the motor 11 is transmitted to a worm wheel 28 at the tape loading side.</p> |
