Abstract
PURPOSE: To reduce power consumption to a constant voltage circuit by the constitution of cooperatively changing over the switch which controls the connection of a photoconductive element and an ammeter and the switch which controls the supply from a power source to a strobe.
CONSTITUTION: When changeover switches 6, 7 are changed over from terminals 6a, 7a to terminals 6b, 7b respectively, an EE mode is set and the constant voltage across a resistance 10 and the current corresponding to the subject luminance of a photoconductive element 14 are supplied to an ammeter 5, whereby correct automatic exposure photographing is accomplished. Even if the changeover switches 6, 7 are neglected to be returned to the terminals 6a, 7a after the use of the device, the camera is normally in a contained state and the supply current to the photoconductive element 14 is slight, thus the power consumption by the ammeter is negligible. Hence, there is no need for considering power consumption by the neglection of turning off of power source switch.
