<p>PURPOSE:To perform a switch of operations with simple constitution and with use of the revolving force of a motor, by providing the 1st and 2nd toothless parts to a switch gear to perform switching between a reproducing action and a cue or review action. CONSTITUTION:A switch gear 18 containing the 1st and 2nd toothless parts 20 and 21 engages with an operation switching time driving gear 17 and at the same time performs switching of operations with revolution of the gear 17. A control member 27 is attached displaceably to a fixed substrate and controls the engagement between the gears 17 and 18. Then the gear 17 is engaged with the gear 18 by a displacement of the member 27, and a sliding substrate 40 is displaced to a reproducing position with a rotary displacement from the part 20 to the part 21 of the gear 18. At the same time, the substrate 40 is displaced to a cue or review position from the reproducing position with a rotary displacement from the part 21 to the part 20.</p> |
