<p>PURPOSE: To obtain a mode changeover mechanism constituted so as to smoothly shift to the queue/review state in a short time without going through the stopping state when this shift is made from the mechanism reproducing state. CONSTITUTION: A take-up gear 9 linked with reel bases 17, 18 and a main pulley 8 are operated by a cam gear 7 in the thrust direction and radial direction, and each operation mode is selected by controlling with use of the attraction and release command of a solenoid 21. The normal reproducing state or inverse reproducing state is selected at the time of shifting the state to the reproducing state from the mechanism stopping state, and the queue state or review state is selected at the time of shifting the state to the queue/review state from the reproducing state, so that the smooth queue/review operation is realized in a short time.</p> |
