Abstract: PURPOSE:To prevent an error on a photograph from occurring by delaying the detection timing of a battery voltage detection signal generation circuit by a specified time in reference to the rising of a signal having a fixed pulse width and setting it near the falling part of the signal having the fixed pulse width. CONSTITUTION:A light emitting display body lighting control circuit 5 is actuated with a trigger signal by a shutter 1 or a switch 2 to drive a light emitting display body 8 or a resistor 9. A lighting control circuit 5 performs the control of time to obtain exposure in accordance with film sensitivity and actuates a detection signal generation circuit 6 to actuate a state holding circuit 7 with a detection signal. When the circuit 7 is in such a state that the life of a battery expires, a lighting inhibition signal is outputted so as to prohibit the lighting of the light emitting display body 8 even though a shutter 1 is released. In the case of imprinting data on a film, the condition of the shortage of exposure is detected promptly and a warning for the battery replacement is given, then imprinting the data is not absolutely performed in the condition of the shortage of the exposure.
