PURPOSE:To perform start/stop of the revolution of a turntable just with the drive power of a main drive motor by moving back the 2nd slide member with a shift member and having a contact between an idler and a turntable and a capstan respectively in response to the shift of the 2nd slide member. CONSTITUTION:An arm 49 is fixed to a shaft 48 implanted to a fixed plate 16, and a shrinkable spring 51 is hooked between the arm 49 and a bent bar 35d formed to the 1st slide member 35. A moving habit is provided to the member 35 by the force of the spring 51 to put an eccentric roll 37 close to a capstan 12. This habitual shift of the member 35 is prevented when the bar 35d hooks a stage part 52 of a restriction lever 52 attached to the shaft 48. The capstan 12 is turned toward an arrow head together with a flywheel 15 and a pulley 11 by the drive function of a main drive motor 9 and via a belt 10. |
