The camera blade drive is configured to operate the blade member 20 that is linked to the rotating driving ring 30. A permanent magnet 31 is provided on the driving ring 30 and a coil 11 rotates the driving ring 30 by magnetic force generated when the coil 11 is conducting. A magnetic member 12 holds the driving ring 30 in a predetermined position by magnetic attraction with the permanent magnet 31 when the coil 11 is non-conducting.

摘要： A base plate is provided with four guide pins and a rotor has four output pins so that each of four blades is provided with a plurality of slots. Individual slots provided to the blades are selectively fitted to the four guide pins and the four output pins so that when the rotor is reciprocated and rotated, the blades are capable of continuously changing the size of an aperture by cooperation of their aperture forming edges while maintaining a regular octagon.
