Claims

[Scope of utility model registration request]

(1) First and second movable pieces are movably arranged at both ends of the magnet, and when the magnet is excited, the first movable piece moves against a spring, and the second movable piece moves against the spring. In addition to retracting the locking plate to prevent the piece from moving,
The shutter drive plate in the charge position is released via the hook lever to start the shutter opening operation, and when the magnet is demagnetized, the second movable piece moves together with the interlocking plate that follows the release plate. A shutter operating device characterized in that the shutter opening/closing plate attached to the shutter driving plate is actuated to start closing the shutter.

(2) The shutter actuating device according to claim 1, wherein the first movable piece is arranged so as to be freely swingable, and the second movable piece is arranged so as to be freely slidable. .
