PURPOSE: To provide an inexpensive compact driving force transmitting mechanism for a camera capable of driving a lens frame and a film by using a single motor.

CONSTITUTION: The driving force transmitting mechanism for the camera is provided with a lens frame driving gear mechanism having a rotary barrel 33 provided with a face gear 33a on the periphery, a film driving gear mechanism winding and rewinding the film, a planetary gear mechanism having an output gear 8, a planetary gear 9 and a gear arm 10 for selectively transmitting the driving force of a motor to the lens frame driving gear mechanism and the film driving gear mechanism, a supply restraining lever 23 moved by a switching lever 30 for driving the lens frame driving gear mechanism forward and backward and executing the engagement/disengagement of the planetary gear mechanism and a rewinding restraining lever 14 moved by a film end detecting lever 20 for driving the film driving gear mechanism forward and backward and executing the engagement/disengagement of the planetary gear mechanism.
