Claims

[Scope of utility model registration request]

The focal point is configured such that the cam part of the control cam causes the leading blade locking member to be pushed in the unlocking direction via an intermediate member whose position at which the cam part of the control cam starts to receive the action changes by changing the set time. In the plain shutter speed control mechanism, the control cam is provided with a protrusion that directly pushes the leading blade locking member for maximum speed control, independent of the cam part, and an intermediate member is provided when controlling the maximum speed. A second time control mechanism characterized in that the cam part is retracted out of the motion trajectory.
