PROBLEM TO BE SOLVED: To obtain a driving mechanism for a camera capable of performing normal and reverse driving at the time of auto-focusing(AF) driving and normal and reverse driving at the time of feeding film with simple constitution by a driving motor by actuating a restricting member by the extending and withdrawing operation of a zoom driving system in order to hold the driving system in an AF driving feasible state and holding a driving system. SOLUTION: When the motor and a motor pinion 1 are rotated counterclockwise(CCW), a sun gear 2 is rotated CCW, and a planet gear 4 is revolved CCW by the rotation of the gear 2, then the gear 4 is revolved and moved to a position where it is meshed with a spool gear 5, so that the gear 5 is rotated CCW so as to wind up the film. Simultaneously, a sun gear 7 is rotated CCW through an idle gear 6 by the CCW rotation of the gear 2, and planet gears 9 and 10 are revolved CCW by the rotation of the gear 7 and revolved and moved to a position where they are meshed with a driving gear 14, so that the gear 14 is rotated CCW and a fork gear 15 is rotated CCW through respective gear trains so as to push out the film. |
