Abstract
PURPOSE:To detect the consumption of a battery power source and to execute warning by constituting a circuit so that it becomes lower than the charging completion voltage value of a flash device and releasing the low consumption mode of a microcomputer. CONSTITUTION:A block I is a circuit for the flash device, a block II is a main control circuit including a storing element as the element of a circuit and a block III is a voltage detection circuit and other sub-control circuit. The block II is connected to a capacitor 4 for backup which is connected to the battery power source 1 through a diode 3. And the block III is connected to a filter capacitor 8 which is connected to the power source through a transistor 6 and a choke coil 7 constituting a filter circuit. The block II to which specified information is given from the block III executes an arithmetic operation for controlling respective acting mechanisms necessary for the photographing action of a camera based on the said information and makes the camera actuate in photographing in specified procedures. Thus, the degree of the consumption of the battery power source can be detected and the warning can be sent out.
