制御装置。[Claims for Utility Model Registration] A blade driving member disposed so as to be movable between a first position and a second position, and to which a driving force is applied from the first position to the second position; and the blade. a locking member that is given an operating habit so as to lock the drive member in the first position; an electromagnet for shutter release control; and a locking member that is movable between an attracted position and a separated position with respect to the electromagnet. an iron piece member that is disposed in the adsorbed position and is pushed by operation from the adsorbed position to the separated position to displace the locking member in a direction to release the lock from the blade driving member against its operating habit; A focal plane shutter comprising two sets of springs, one end of which is latched (engaged) to the iron piece member to give the iron piece member an operating habit from the adsorbed position to the separated position, the springs having: The other end is latched (engaged) to the blade driving member, and when the blade driving member is in operation from the first position to the second position by releasing the lock, the driving force of the blade driving member a first time period acting as an assisting force; and an intermediary member that pulls the iron piece member from the separated position to the attracted position while releasing the pushing force against the locking member by the driving force of the blade driving member. and a third time period in which the iron piece member acts as a reducing force with respect to the driving force of the blade driving member after the iron piece member reaches the adsorbed position. Control device for focal plane shutter.
