ABSTRACT:
A rechargeable photographic camera includes an interlock circuit that automatically inhibits operation of the camera flash when the camera is mated with a charging cradle, regardless of the condition of a manual on-off flash switch. The rechargeable battery of the camera therefore is assured of receiving a full charging current even if the flash unit is left on when the camera is mated with the charging cradle.
