    摘要: A focal plane shutter for a camera comprises opening and closing blade units operable to open and close a shutter opening of the camera. Each blade unit has a leading blade and trailing blades in superposed relation to the leading blade. The leading blade and the trailing blades are supported by arm members through hollow pivot pins. The hollow pivot pins supporting the leading blade of each blade unit are covered by the trailing blades. Due to the use of hollow pivot pins, the overall weight and driving force of the blade units are effectively reduced to thereby make the shutter free of operational impact without light leakage.

    摘要: Disclosed is an actuator device for an optical device. The actuator device includes a core arranged in an optical device inside of which an optical path passes through, a coil wound around the core, and a rotational magnet formed into an approximately cylindrical shape, at least one end of which includes a bearing portion in an axial direction, and which rotates according to a direction of a magnet field output from the core by electrifying the coil. The actuator device further includes a drive pin rotated in association with the rotational magnet, a base member securely supporting the core and rotatably supporting the rotating magnet, and an optical member moving in and out of the optical path based on rotation of the rotational magnet.

    摘要: A focal plane shutter comprises a base plate having a shutter opening, at least one shutter sector group having sectors, and arms pivotally connected to and supporting the sectors for displacing the sectors relative to the shutter opening. At least a first one of the sectors comprises an intermediate sector interposed between a second one of the sectors and one of the arms connected to and supporting the second sector. The intermediate sector has an edge portion disposed proximate a connection of the second sector and the arm connected to and supporting the second sector. At least the edge portion of the intermediate sector is thinner than other portions thereof to facilitate smooth displacement of the sectors relative to the shutter opening without any obstruction.

    摘要: When a brightness level of an object is below a predetermined level, an ND filter is removed from an iris opening to fully open the iris opening, and when the brightness level of the object is above a predetermined level, the ND filter is placed to the iris opening to fully close the iris opening. When the ND filter is moved between the fully-opened state and the fully-closed state, an exposure change amount corresponding to an amount offsetting the exposure change amount due to a state transition is generated by controlling iris blades.
