摘要： A light controller includes a substrate having an optical path opening, a blade unit with a blade mounted on the substrate for opening and closing the optical path opening, a driver unit for driving the blade, and a stopper unit for restricting a movement of the blade between an open position and a closed position. The stopper unit includes a long hole formed in the blade and extending in a direction that the blade moves, and a stopper pin fitted into the long hole. The long hole is disposed at a position away from the optical path opening in an entire range that the blade moves. Accordingly, when the blade unit has a plurality of blades, it is necessary to arrange only the stopper pins having a number equal to the number of the blades on the substrate, thereby reducing a size of an apparatus.
摘要翻译：光控制器包括具有光路开口的基板，具有安装在基板上的用于打开和关闭光路开口的叶片的刀片单元，用于驱动刀片的驱动器单元和用于限制刀片运动的止动器单元在打开位置和关闭位置之间。止动器单元包括形成在叶片中并沿着刀片移动的方向延伸的长孔和装配到长孔中的止动销。长孔设置在与刀片移动的整个范围内远离光路开口的位置。因此，当叶片单元具有多个叶片时，需要仅设置与基板上的叶片数相等的止动销，从而减小装置的尺寸。

摘要： A high-performance exposure adjusting device for a camera has a magnet rotor united with an aperture member capable of steadily assuming three exposing positions according to the polarity of a direct current applied to a coil surrounding the rotor. When applying no current to the coil, the aperture member takes its magnetically neutral position to form a full aperture and is magnetically stabilized by a yoke surrounding the rotor. When the direct current of one polarity is applied to the coil, the aperture member rotates in one direction to form a first reduced aperture, and when the polarity of the current applied is reversed, a second reduced aperture is formed.

The outside yoke has a trough shape, and two opposed magnetic pole-guide pieces, between which magnetic poles of the permanent magnet are sandwiched. The rotor has a bearing portion in the internal circumference wall of the body, and the bearing portion engages a shaft portion of the inside yoke. When a magnetic field is generated by the coil, a rotation force is applied to the rotor, resulting in a structurally-simple magnetic circuit.
