摘要： The light-quantity control apparatus includes a base member, and a light-quantity control blade having a light-quantity control portion to control a quantity of light passing through a fixed aperture and a supported portion rotatably supported with respect to the base member. The light-quantity control portion and the supported portion of the light-quantity control blade are each rotated along a plane parallel to the aperture face, an intermediate portion thereof formed between the light-quantity control portion and the supported portion has a tilt with respect to the aperture plane toward the optical axis direction so that the light-quantity control portion is disposed distant from the supported portion in the optical axis direction. Thereby a concave space facing the fixed aperture is formed inside in the radial direction than the light-quantity control blade.

摘要： When a stepping motor is used as a driving source for a shutter device, if the stepping motor loses synchronization because of variations in load during driving or the like, it becomes unable to rotate a driving ring at that time, and this disables an exposure operation. In a first zone where a driven member is driven, but a light shielding member remains in a closed state or an open state, the motor drives the driven member in open-loop driving mode. In a second zone where the driven member is driven, and thus the light shielding member moves to the closed state or the open state, the motor drives the driven member in feed-back driving mode.

摘要： An optical shutter apparatus has at least one shutter blade that is movable between a first position blocking at least a portion of an aperture and a second position spaced apart from the first position. A linkage member is coupled to the at least one shutter blade and has a magnetic material. An actuator is coupled to the linkage member and is energizable to translate the at least one shutter blade between the first and second positions. An intermediate plate has a friction surface of a non-magnetic material. A magnet positioned away from the friction surface of the intermediate plate is disposed to urge the linkage member against the friction surface of the intermediate plate.
