  • Patent number: 7771132
    Abstract: A shutter unit is equipped with a base plate, a yoke, a coil that is attached in the middle of the yoke to excite the yoke, and a rotor that rotates in a predetermined direction by excitation of the yoke. A lens frame is formed on the base plate. The yoke has a substantially annular shape so as to be disposed on the base plate encircling the circumference of the lens frame. Thus, by forming the yoke in a substantially annular shape, the yoke and the coil can be moved toward an optical axis, and consequently, the shutter unit can be downsized.
