摘要： A blade drive device includes: a board having a shutter opening; a blade for adjusting an amount of light entering the shutter opening; and a transmitting member for transmitting a drive force to the blade. The transmitting member includes a drive pin swinging about a given support point. The blade has a first cam slot engaged with the drive pin and swinging about a given support point in conjunction with a swinging of the drive pin. The first cam slot includes a first permitting area and a first restricting area. The blade is permitted to swing when the drive pin is located in the first permitting area. The blade is restricted from swinging when the drive pin is located in the first restricting area.
