Abstract

PURPOSE:To eliminate adverse influence caused by hazardous light by using a shutter base where the end surface of an aperture is integrally formed into roughly a circular shape. CONSTITUTION:A chamfered part 33a used for smoothing the travel of a rear blade sector is formed on the end surface of the aperture of the shutter base 20. The end surface 33b of the aperture is formed circularly and integrally. Since the end surface 33b is formed circularly, the hazardous light 71 from the side of the shutter base 20 is hardly reflected by means of the end surface 33b in useless fashion, and its route is the surface of a partition 12, thereby giving almost no adverse influence to a filter 50. Therefore, reflection prevention coating, which has been applied to the end surface 33b of the aperture of the shutter base 20, is not needed, thereby substantially reducing man hour and costs.
