<p>PURPOSE:To reduce a rush current and to perform switching to respective modes through one driving source by sliding a slider for mode switching through one control motor and performing the switching to the respective modes. CONSTITUTION:Parts from the control motor 4 to the 7th gear 31 are assembled on a substrate 20 and unitized, and the hollow shaft 32 of this unit is fitted loosely in a take-up reel turntable shaft 2 supported pivotally on a mechanism substrate 33 such as a chassis. Then, this unitized substrate 20 is fixed at a specific position with screws 34 and 35. On the other hand, the 8th gear 38 engaging the 7th gear 31 is fitted rotatably to a vertical shaft 37 fixed to the mechanism substrate 33, and a slider driving gear 6 united with this 8th gear 38 engages the rack 7 of a slider 1 for mode switching. Further, the mode switching slider 1 has its long-sized hole guided by the vertical shaft 37 and also guided by another couple of long holes and avertical shaft to slide as shown by arrows (a) and (b).</p> |
