Abstract

PURPOSE: To perform accurate flash photographing without providing any release lock mechanism or the like by controlling the shutter release signal by way of the gate which is opened by the charging completion signal at the selection of non- charged lock mode.
CONSTITUTION: When the non-charge lock mode is held selected by the external operation, this is decoded and the output of a gate G3 becomes high level, causing a gate G5 to open and the strobe charging completion signal STB to be applied to the gate G5 through an inverter. As a result of this, the output of the gate G5 inverts to a low level to unlock the gate G6 of the camera by the lock signal of high level, thus the transmission of the release signal is controlled by the gate G6 which is opened only by the charging completion signal of the strobe device at the selection of non-charging lock mode, whereby the current supply to the taking magnet is controlled. Such constitution controls the circuits in such a manner that the release signal is transmitted only when necessary conditions are satisfied, without using any direct locking mechanism and the like, thus the accurate flash phototraphing is accomplished.
