Claims

[Scope of Claim for Utility Model Registration] A shutter blade drive member connected to the shutter blade of a focal plane shutter and movably provided to move the shutter blade back and forth to the position of the exposure aperture in order to open and close the exposure aperture. a holding member for stopping the shutter blade drive member in the shooting preparation position; a motor for driving the shutter; and a motor that is moved by the rotational force of the motor.
After the motor has rotated by a predetermined amount due to the release operation, the motor engages with the shutter blade drive member, and the drive member is released from the stopped state by the holding member, and the shutter blade is activated. A driving device for a focal plane shutter, comprising: a transmission member that moves in a direction to open the exposure aperture;
