PROBLEM TO BE SOLVED: To prevent the number of gears from being increased and the diameter of a gear from getting large in the case of dividing the driving force of a motor from a reduction gear train to a speed-up gear. SOLUTION: This camera is equipped with a driving mechanism for transmitting the driving force from an output gear 2 integrally rotating with the output shaft of the motor 1. The driving mechanism is constituted by using a three-step- gear 3 obtained by integrally forming a 1st reduction gear part 3a decelerating the rotation of the output gear, a 2nd reduction gear part 3c decelerating the rotation transmitted to the 1st reduction gear part and transmitting it to a 1st driving system and a speed-up gear part 3b accelerating the rotation transmitted to the 1st reduction gear part and transmitting it to a 2nd driving system.
