Abstract
A flash changeover device for a shutter is operative when the exposure operation is performed by cancelling the retention on a shutter blade control in the charged state by the operation of an actuating member which has previously been charged and is actuated by a shutter release operation. The device includes a flash system changeover member, a switching member, a synchronizing switch and wherein the switching member is oscillatably mounted on the changeover member so as to close the synchronizing switch in connection with the operation of the actuating member when the flash system changeover member is set to a first position and to close the synchronizing switch in connection with the shutter blade opening operation of the shutter blade control member when the flash system changeover member is set at a second position. The synchronizing switch has contacts having relative positions which are independent of the position of the changeover member when the synchronizing switch is in the open state.
