IPC: G03B9/36
Filed: 2000-03-31
Abstract: PROBLEM TO BE SOLVED: To enhance a light-shielding property by improving the close contactness of split sectors with each other without necessitating a high working technique. SOLUTION: Sector groups 3 and 6 consisting of the sectors 3a-3e and 6a-6e plurally split are disposed between base plates 1 and 2 having a shutter aperture. Both sector groups are moved between a first position at which it covers the shutter aperture and a second position at which it is withdrawn from the shutter aperture by a shutter driving mechanism 10. A lower protrusion 15f is provided on the lower surface of a locking pawl 15 in the shutter driving mechanism.
