Claims

[Claims for Utility Model Registration] An opening/closing member provided with an operating habit in the opening direction of a shutter blade, and an operating habit of the shutter blade in the closing direction capable of returning the opening/closing member against the operating habit. a closing drive member capable of locking the closing drive member in an unoperated tensioned position with respect to the opening/closing member, and a closing actuation locking member having an operating habit in the unlocking direction; locking the member in a tensioned position that maintains the shutter blade in a closed state;
an opening operation locking member that holds the closing operation locking member in a locked state with the closing drive member; and a direction in which the opening operation locking member is locked with respect to the opening/closing member and held with respect to the closing operation locking member. a direction in which the closing drive member is displaced against the actuation habit by the state in which the closing drive member is placed in the tensioned position, causing the opening actuation locking member to release the locking and holding; an opening preparatory member that provides an operating behavior of; an opening action lock holding member that is provided with an action behavior in a direction capable of holding the release action locking member in its locking and holding position; , which is disposed opposite to an electromagnet that is demagnetized by an exposure control signal, and operates the opening operation locking holding member against its operating habit by the attracted operation due to the excitation operation to release the holding on the opening operation locking member. At the same time, the closing operation is such that the closing operation locking member is restrained in the attracted state against its operation habit, and the locking of the closing drive member is released by releasing the restraint by releasing the attraction due to the demagnetization. An electric shutter equipped with an electromagnetic release device characterized by comprising an iron piece member that enables operation of a locking member.
