摘要： According to the present invention, a stepping motor driving apparatus having a rotor and a stator in n (an integer equal to or larger than 2) phases for moving a moving body is provided. The stepping motor driving apparatus includes a driver for selectively supplying to the stator a first current pattern for rotating the rotor at a first pitch and a second current pattern for rotating the rotor at a second pitch different from the first pitch based on a drive switching signal. The driver switches the first current pattern and the second current pattern at a point where a torque generated by the first current pattern is equal to a torque generated by the second current pattern and supplies the first current pattern or the second current pattern to the stator.

摘要： The swing centers of guide shafts in inclination adjustment of an optical head are set to be on a plane which is perpendicular to a predetermined radial direction of an optical disk and has thereon the rotation axis of a disk motor. When the inclination adjustment of the optical head is conducted, relative gap variation between the optical head and the optical disk does not occur, and the inclination adjustment is realized within a movable range of an objective lens. The inclination angle of the optical head in a radial direction of the optical disk is adjusted by simultaneously moving upward or downward ends of two guide shafts, and the inclination angle of the optical head in a tangential direction of the optical disk can be adjusted by moving upward and downward one end of at least one of the guide shafts.

In each pair of adjacent lenses, when projected parallel to their optical axis, one lens located closer to the second opening has a greater projection than the other lens located closer to the first opening. The barrel has inner side surface portions, which are arranged parallel to the center axis to define cross sections corresponding to the respective projections of the lenses. In each pair of adjacent inner side surface portions, one portion located closer to the second opening has a greater cross section than the other portion located closer to the first opening. The barrel has main grooves cut on the inner side surface portions to run from the first opening toward the second opening. Each of the lens units is bonded to an associated inner side surface portion with an adhesive that fills at least partially the main grooves on the inner side surface portion.

摘要： A solid-state imaging device according to the present invention includes, on an imaging surface, a plurality of unit pixel regions being arrayed at a first pixel pitch along a Y direction and at a second pixel pitch along an X direction. One of two adjoining unit pixel regions 1 along the Y first direction includes a first photodetecting portion 1a having a first opening ratio, and the other includes a second photodetecting portion 1b having a second opening ratio which is lower than the first opening ratio. When the first photodetecting portion 1a is moved imaginarily by a first pixel pitch along the Y direction, the first photodetecting portion 1a covers the entire second photodetecting portion 1b. At this time, a portion of the first photodetecting portion 1a that does not cover the second photodetecting portion 1b functions as an imaginary third photodetecting portion. From a difference between signals output from the photodetecting portions 1a and 1b, an imaginary pixel signal which is in accordance with an amount of light entering the imaginary third photodetecting portion is obtained.
