PROBLEM TO BE SOLVED: To provide a power supply device capable of efficiently supplying power. SOLUTION: A camera body 1 is provided with a motor 6 for advancing and rewinding a film, a control circuit 11 which drives and controls the motor 6, and power supplies 3, 8. An interchangeable lens 2 is provided with a motor 22, which drives a blurring correcting lens 29, a control circuit 23 which drives and controls the motor 22, a motor 25 which drives a photographing lens 27 for adjusting the focus of the lens, a control circuit 26 which drives and controls the motor 25, a blurring detecting portion 24 for detecting blurring, and the like. The power supply 3 supplies power to the motors 6, 22, 25 which consume large amount, and the power supply 8 supplies power to the control circuits 11, 23, 26 and the blurring detecting portion 24 which consume small power amount. For this reason, the control circuits 11, 23, 26 and the blurring detecting portion 24 can be stably supplied with power, even if the motors 6, 22, 25 consume more power. |
