Claims

[Scope of utility model registration request]

(1) The closing operation of the shutter blades is performed by a drive spring, and the closing operation of the shutter blades is performed using a permanent magnet by energizing a drive coil with a drive pulse generated in a control circuit according to a field brightness information signal. In a strobe synchronization device for an electromagnetically driven program shutter that is operated by electromagnetically cooperating, a delay circuit inputs the drive pulse of the precursor control circuit and provides a predetermined delay time;
It is connected to the delay circuit and operates to energize the strobe device by its output. (2) A strobe synchronizer for an electromagnetically driven program shutter, which is determined to correspond to a mechanical delay time until the shutter opens and stops operating. "another delay circuit" which provides a delay time different from time, and a gate other than said first-mentioned gate connected to said another delay circuit and whose output serves to energize a strobe device. a selection circuit connected to selectively operate either the first-mentioned gate or the other gate in response to the field brightness information signal of the control device, and the another delay gate; The delay time of the circuit is determined to correspond to at least the mechanical delay time from the time when the drive pulse disappears when the shutter blade is fully opened until the shutter blade starts closing and the shutter blade opens, and the selection circuit Drive pulse during operation
When the drive pulse disappears, the first gate is opened, and when the drive pulse disappears while the shutter blade is fully open, the other gate is opened, and the selection is made according to the field brightness information signal. A strobe synchro device for an electric Ma program shutter according to claim (1) of the registered utility model.
