電源装置。 A main battery that supplies power to each device of the camera and a microcomputer that controls the operation of each device when attached to the camera body, and a main battery that supplies power to the microcomputer when the main battery is not attached or in operation. In a power supply device for a camera equipped with a backup battery that supplies power, a main battery installation determining means changes the state of an output signal depending on the installation state of the main battery, and the main battery installation determining means changes the state of the output signal depending on the installation state of the main battery. A backup voltage detection means for detecting the output voltage of the backup battery, and a reset means for outputting a reset signal for initializing the microcomputer when the voltage detected by the backup voltage detection means falls below a predetermined voltage are provided. Camera power supply.
