る電気シヤツタ。 A shoeing plate is provided with a biasing force in one direction by winding up, and is rotatably supported on the main plate to provide rotational habit, has a pin at one end, and a suction plate and a switch changeover pin at the other end. A release lever provided, a shutter blade that opens and closes the shutter according to the rotation of the release lever, a magnet disposed on an extension of an arcuate locus along which the suction plate moves, and a switch switching pin. It consists of a switch that turns on and off the time-switch contact and synchro switch contact, which are placed on the extension of the moving arcuate trajectory, and a time-switch circuit that creates the shutter opening time. Then, the power of the timer circuit is turned on to excite the magnet, and one end of the released picking plate hits the pin, and the releasing lever is rotated in the opposite direction against the rotational habit, thereby causing the attracting plate to rotate. is attracted to the magnet to open the shutter, turn off the time-setting switch contact using the switch changeover pin, turn on the synchro switch contact, and turn the opening lever by the magnet-off signal from the time-setting circuit. bring it back,
An electric shutter characterized by being configured to close the shutter.
