PURPOSE:To detect a minimum operating voltage level of the driving means of a camera body even while feeding a strobe device by feeding power source to the strobe device in time division and checking the supply voltage at the time of inhibiting feeding. CONSTITUTION:A driving means 2 like a motor or a magnet is fed by a power source 1, and a strobe device 3 is fed by the power source 1 also. A time division means 4 supplies power to the strobe device 3 in time division. A supply voltage checking means 5 receives the output signal of the time division means 4 and the supply voltage and checkes the supply voltage only when a boosting circuit is in the operation inhibiting state. Thus, a camera supply voltage checking device is obtained which detects the minimum operating voltage level of the driving means of the camera body even while supplying power to the strobe device.
