Abstract
In a zooming-focusing type camera, a driving force of a motor is selectively transmitted to a zooming mechanism for controlling a focal length of an optical lens system, a film winding mechanism for winding a film by a length corresponding to one frame and a film rewinding mechanism for rewinding the film into a film cartridge by a switching mechanism. The switching mechanism has a planet gear revolving among and selectively engages with one of a winding gear of the film winding mechanism, a rewinding gear of the film rewinding mechanism and an input gear of the zooming mechanism for transmitting the driving force of the motor.
