PROBLEM TO BE SOLVED: To obtain a motor-driven camera capable of making noise quiet and realizing high-speed rotation by providing an ultrasonic motor performing the driving of 1st operation and a DC motor performing the driving of 2nd operation. SOLUTION: The ultrasonic motor USM1 is a motor performing automatic focusing by moving a part of a photographing lens 8 based on an AF control signal and is arranged inside the mount surface of a camera body. The DC motor M1 is a motor performing motor-driven zooming by moving a part of the lens 8 based on a zoom control signal and is arranged in the barrel of the lens 8. The ultrasonic motor USM2 is made cylindrical, is a motor for winding the film F and is arranged in a film take-up spool 9. The DC motor M2 is made cylindrical in the same manner, is a motor for rewinding the film F and is arranged near the cartridge chamber 10 of the film F. |
