ABSTRACT:
In a camera of the type including an electronic flash light unit with a relatively large-capacity capacitor and an electronic shutter which are supplied with power from a common power source battery, the power source battery is checked to determine whether it is in good condition for service. When the battery is electrically connected to the flash light unit, the operation of the battery checker to detect the voltage across the battery, is prevented by either a mechanical switch or a slide cover that covers the indication of the battery checker.
