    摘要: When a driving member is rotated counterclockwise by a single motor with a pair of sectors biased in the closing direction by a biasing spring, a first driving pin causes an operating lever to rotate clockwise. The pair of sectors pivot in opposite directions to each other in association with the driving lever to reach a first position where the sectors are fully open without overlapping the lens opening. When the driving member is rotated clockwise, a second driving pin also causes the operating lever to rotate clockwise. The pair of sectors pivot in opposite directions to each other to reach a second position, that is, a half-open position where an opening smaller than the lens opening is obtained. At this time, The second driving pin abuts on a part of one sector to restrain the displacement of the driving member. Accordingly, the driving member is prevented from overrunning, and no hunting occurs.

    摘要: A rocking motor comprises a coil wound around a hollow coil bobbin. A rotor is rotatably mounted at a position close to an end portion of the coil bobbin. The rotor has a center shaft and a permanent magnet and is magnetized with two poles such that the positions of the poles are located close to the coil and the magnetization angle is greater than 90 degrees but less than 180 degrees. The positions of the poles of the rotor and the coil are adjacent to one another so that a rotary torque can be efficiently obtained by a magnetic force generated by the coil. The rocking motor can generate a high power output with a relatively low power supply and its operational performance is not adversely affected by an external magnetic field.

    摘要: In the distance measuring device for an automatic focusing camera, the reliability is improved by preventing the device from electric noise, and the structure is simplified so as to provide interchangeability to reduce the production cost. A light receiving lens 2 and a multilayer printed circuit board 3 are mounted on a holder 1. A potting frame 6 is provided on the lens-facing side surface of the printed circuit board 3. An optical sensor 4 and an IC 5 are both mounted within a space 3 enclosed by the potting frame 6, and sealed by a protecting resin 7 simultaneously. Further, resistors S and capacitors C of a distance measuring circuit are mounted on the opposite surface of the printed circuit board 3. Both the surfaces of the printed circuit board 3 are connected to each other via a through hole to construct the distance measuring circuit. The protecting resin 7 transmits light having specified wave lengths. The light reflected from a subject to be photographed is received by the optical sensor 4 after passing through the protecting resin, and a distance to the subject is calculated on the basis of the received light data.
