Abstract
PURPOSE: To obtain a miniaturized shutter mechanism by superposing an inner blade on an outer blade in the refuge position of right and left shutter blades which cover the aperture of a photographing lens and storing them.
CONSTITUTION: At least either of shutter blades which cover the aperture 1 of the photographing lens to put the aperture between them is constituted of the blades 21 and 23, the outer blades 22 and 24. And the inner blades 21 and 23 are supported to freely turn between the cover position where the mainly cover near the center of the aperture 1 and the refuge position where they refuge to the side of the aperture (1) and the outer blades 22 and 24 are supported to freely turn between the cover position where they mainly cover near the outer side of the aperture 1 and the refuge position where they refuge to the side of the aperture 1. The inner blades 21 and 23 and the outer blades 22 and 24 jointly cover the aperture 1 of the photographing lens in the cover position and they are superposed to be stored in the refuge position. Thus, the miniaturized shutter mechanism can be obtained.
