Abstract
PURPOSE: To open and close the shutter accurately, by releasing the stopping of the moving body by pushing operation of the shutter operating member, and opening and closing the shutter blades by the movement of the moving body.
CONSTITUTION: Being coupled with film winding-up action, a moving body 5 moves to the left, and a fitting piece 6a rides over a protruding part 16a of a shutter blade driving member 16 to fit to this. At this time, when an aperture value setting member is operated, a cam 36 turns in clockwise direction being coupled thereto, and a fitting member 31 moves to the left. Then a shutter operating member is pushed, the moving body 5 moves to the right, and the fitting piece 6a climbs a slope 31a while rotating the shutter blade driving member 16 in clockwise direction. As a result, the shutter 3 is opened, and strobe is emitted light. As the moving body 5 moves further, the fitting piece 6a releases the stopping and the shutter blade driving member 16 turns counterclockwise, so that the shutter 3 is closed. Thus, in a simple constitution, the shutter may be opened and closed accurately.
