Abstract
In order to utilize the advantage of compactness of the current-attraction type solenoid devices and the advantage of two-solenoid electric shutter of being easily linked with other mechanisms, the electric shutter has such a structure that a reciprocating shutter charging member is not returned at the completion of the shutter charging operation but returned when the first and second solenoids are energized after the picture-taking operation is initiated, and that a resetting member is retract from the moving area of the moving members of the first and second solenoids in relation to said returning motion.
