Abstract

PURPOSE:To economize the energy of an internal battery, by counting the duration of the operation of an electronic circuit for camera by a timer of an incorporated electronic clock to warn the user that he forgets to turn off a power switch. CONSTITUTION:When a power switch 22 of a camera is turned on, a timer 14 of an incorporated electronic clock block 11 starts counting; and the output of the timer 14 sets a flip-flop circuit 15 when the switch 22 is not turned off for a prescribed time (for example, 10min). After the elapse of a set prescribed time (desirably, several tens minutes to one hour), a liquid crystal display 19 and a warning display means 20 such as a speaker are operated to warn the user that he forgets to turn off the switch 22. At this time, since the output level of an inverter 16 becomes 0, a switch 23 is turned off to cut off automatically the current to a camera controlling circuit.
