1. A power supply circuit for a camera comprising:

  • (a) a power source;

    (b) voltage detection means which is connected to said power source for detecting the voltage of said power source and which develops a signal when the voltage of said power source is beyond a predetermined voltage value;

    (c) signal forming means which forms an output signal after a predetermined time after the power source voltage is detected by said voltage detection means;

    (d) an electrical circuit for controlling a photographing operation; and

    (e) a power supply circuit connected to the power source to form a power supply path to said electrical circuit in response to the signal produced by said voltage detection means and the signal produced by said signal forming means.
