ンズシヤツタのトリガタイミング調整機構。[Scope of Claim for Utility Model Registration] In a lens shutter that uses a photo sensor to detect movement of the peripheral edge of a shutter blade to obtain a trigger signal, a slit is formed to restrict the width of a beam of light emitted from the photo sensor, and the lens shutter rotates around an aperture. It consists of a shutter blade holding plate in which a long hole is formed for movement, and a shutter base plate in which a screw hole is formed in order to fix the shutter blade holding plate and the photo sensor is arranged on the outer periphery of the shutter blade holding plate. By slightly moving the plate along the elongated hole in the circumferential direction around the aperture, the width of the light beam emitted from the photo sensor is regulated by the slit, and the relative position of the photo sensor and the peripheral edge of the shutter blade is adjusted. A trigger timing adjustment mechanism for a lens shutter, characterized in that the trigger timing adjustment mechanism changes the trigger timing of a lens shutter.
