Abstract:
A shutter for a camera, comprising: a base plate having a shutter opening formed therein; at least one shutter sector disposed adjacent the base plate for opening and closing the shutter opening and having a through-hole formed therein; an operating member having a projection penetrating the through-hole of the shutter sector to cause the shutter sector to undergo movement therewith to selectively open and close the shutter opening; and an actuator for driving the operating member; wherein a gap is provided between the through-hole and the projection in a direction of movement of the projection and having a sufficient size such that the operating member is driven without the projection coming into contact with the shutter sector immediately after the actuator starts to drive the operating member to open or close the shutter opening, and is caused to accelerate before the projction comes into contact with the shutter sector to cause the shutter sector to undergo movement therewith.
