Abstract:
PROBLEM TO BE SOLVED: To provide a camera blade drive device that can suppress an impact sound even when a high-speed operative quite thin blade member is stopped at a prescribed position, can prevent a bound, and is excellent in durability of a buffer member.SOLUTION: A lever member 10 is provided that is formed to be thicker than an ND filter blade 8 and operated simultaneously with the ND filter blade 8, and abutting parts 10b-1 and 10b-2 of the lever member 10 are abutted against a buffer member 11. Since the ND filter blade 8 is not directly abutted against a stopper having the buffer member, an impact sound can be suppressed, a bound can be prevented, thus, durability of the buffer member can be improved.
