Abstract

PURPOSE: To stop the light emission operation of the dispaly device thereafter when the battery voltage is below the specified by detecting the battery voltage of the time when the first light emission operation of the film imprinting display device is done after shutter input.
CONSTITUTION: When the first light emission of an imprinting display device 9 is done after shutter input, a battery voltage detecting circuit 10 detects the battery voltage. If at this time the battery voltage is above the specified value, no output signal is emitted from a system control circuit 11 and the display device 9 performs normal film imprinting operation. On the other hand, if the battery voltage is below the specified value, a display stop signal is emitted from the system control circuit 11 to a decoder drive circuit 8 through line 11a, so that the operation is stopped. At this same instant, a display instruction signal is led into a decoder drive circuit 4 through line 11b, so that it is displayed in a monitor display device 5 that the contents of a clock counter 3 have not been imprinted.
