Abstract: An electronic device for reading or writing to an optical disc includes a base and a traverse module set on the base. The base defines a receiving portion for receiving the optical disc. The traverse module is used for rotating and supporting the optical disc and comprises at least one friction-reducing component. The at least one friction-reducing component protrudes out of the bottom of the receiving portion and is positioned between the optical disc and the traverse module for preventing the optical disc from rubbing against the bottom of the receiving portion.

Abstract: There is provided an information-processing equipment including an optical disc drive 40 within a chassis 31 thereof, the optical disc drive comprising: a turntable 41 for rotatably supporting an optical disc; an optical pickup 42 for recording an information signal onto the optical disc and/or reproducing an information signal recorded on the optical disc, and a movement mechanism 43 for moving the optical pickup in a radial direction of the optical disc; wherein a step part 37 extending in a predetermined direction Ls is formed on an inner surface of the chassis in an area where the optical disc drive is to be fixed, and wherein the optical disc drive is fixed in the area on the inner surface of the chassis at three portions 46A, 46B, 46C positioned straddling the step part.

Abstract: There is provided an optical disc drive comprising: a chassis assembly formed in a box shape, including a chassis; and a tray on which an optical disc is loaded, wherein: the tray is able to move between a close state in the chassis assembly and a open state ejecting form the chassis assembly; the optical disc drive further comprises a flexible wiring member for connecting a first circuit board mounted on the chassis and a second circuit board mounted on the tray; the flexible wiring member includes a thicker reinforced part in a part of the flexible wiring member than in the other part of the flexible wiring member; and the reinforced part has a width which is narrower at an end on the chassis side than the other part of the reinforced part.

Abstract: A lightweight radio/CD player for vehicular application is virtually “fastenerless” and includes a case and frontal interface formed of polymer based material that is molded to provide details to accept audio devices such as playback mechanisms (if desired) and radio receivers, as well as the circuit boards required for electrical control and display. The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides EMC, RFI, BCI and ESD shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. The PCB architecture is bifurcated into a first board carrying common circuit components in a surface mount configuration suitable for high volume production, and a second board carrying application specific circuit components in a wave soldered stick mount configuration.

Abstract: An optical pickup device includes an optical system unit, a circuit board to control the optical system unit, and send and receive signals, a housing to place the optical system unit and the circuit board, and a flexible printed circuit board to connect electrically with the circuit board, extend to an outside from the housing, and fold back an extended portion, an extended direction of which is changed, in which the flexible printed circuit board is folded back so as to be faced to a side surface of the housing positioned at an extended proximal portion of the flexible printed circuit board, and a dead space of an optical disc apparatus to be mounted with the optical pickup device can be effectively used without making the apparatus large and thick, taking an inner space widely.
