    摘要: A stepping motor driving system includes: a stepping motor that rotates at a predetermined angle according to a driving pulse signal, a vibration detector that detects vibration to output a vibration signal, and a stepping motor control unit that controls the driving pulse signal, which is applied to the stepping motor, to rotate the stepping motor at the predetermined angle. The driving pulse signal includes a start-up current which is required for rotating the stepping motor at a unit angle and a holding current which maintains a rotational angle of the stepping motor rotated by the start-up current. The stepping motor control unit changes the level of the holding current according to the vibration signal which is outputted from the vibration detector.

    摘要: A disc transfer section for transferring an optical disc by guide members and a transfer roller is disposed adjacent to an opening of a casing 110. A detector 500 for detecting the optical disc is disposed adjacent to the opening. When unloading the optical disc, the peripheral edge of the optical disc contacts with slide members so that the slide members are slid, thereby sensor switches SW1 to SW4 are appropriately switched on and off. Based on a time difference between the timings of the on/off switchings, the relation between a movement trajectory of the center of the optical disc and an axis of symmetry that is a straight line indicating a transfer direction at the center of the opening is judged in order to control the drive of a transfer motor according to the movement trajectory. The amount of advancement when the unloading is completed is kept constant.

    摘要: A support (611) that is substantially cylindrical so as to be received by a disk hole (1NA) and has a positioning portion (612) on a circumference adjacent to a first axial end is provided with a concave portion (613) of which both ends open to the circumference along a radial direction. A first engaging portion (614) protrudes from around the circumference at which a first axial end of the concave portion opens substantially opposes to the positioning portion with a gap equal to or more than a thickness of an optical disk (1N). A moving member (615) is disposed in the concave portion in a manner movable along a radial direction of the support. A second engaging portion (616) protrudes on an end of the moving member at a position corresponding to a second axial end of the concave portion.

    摘要: An optical pickup 200 is arranged between optical discs 10A and 10B rotatably supported with the recording surfaces 10Aa and 10Ba facing each other, the optical pickup being movable along the recording surfaces 10Aa and 10Ba. A laser beam of two wavelengths emitted from a semiconductor laser 201 is respectively reflected in opposite directions by a polarized beam splitter. The reflected laser beams are respectively condensed on the recording surfaces 10Aa and 10Ba via objective lenses, and the laser beam traveling back along the same optical axis is received and processed. No moving member is required, which enables downsizing.

    摘要: A record medium reproduction unit has a main casing, a transfer device, a pair of sensing pins, a sensing device, and a decision device. The transfer device transfers a larger disk record medium and a smaller disk record medium into and out of the main casing. The sensing pins are movable toward and away from each other and each contact an outer edge of the larger disk record medium when the larger disk record medium enters the main casing. The decision device determines which is inserted into the main casing, the larger disk record medium, the smaller disk record medium, or a special form record medium such as a card-shaped CD based on information supplied from the pair of sensing pins.
