ABSTRACT:
A battery check device which assesses a state of exhaustion of a battery installed in a camera, and which can accurately assess at any time the state of exhaustion of the battery according to the drive state of a camera mechanism, such as a mirror. The battery check device includes a voltage detection device to detect the voltage of the camera battery, a drive detection device to detect the required time needed to drive the camera mechanism, a memory in which is stored the required time detected by the drive detection device, and a calculating device which inputs the battery voltage detected by the voltage detection device and the required time which has been recorded in the memory, and calculates a degree of exhaustion of the battery corresponding to these values. A display then displays the degree of exhaustion of the battery which has been found by the calculating device.
