摘要： An optical pickup apparatus comprises a laser beam source to generate laser beam, and a laser driving circuit to drive the laser beam source. The laser driving circuit is connected to a flexible substrate and arranged in a groove or hole provided in the vicinity of that portion of an optical pickup housing, to which the laser beam source is fixed. The laser driving circuit is connected through a heat conduction member to an upper cover among upper and lower covers, the upper cover being close to the laser driving circuit. Thereby, heat generated from the laser driving circuit is conducted through the heat conduction member to the upper cover to be transferred outside the optical pickup apparatus while being scattered in an inplane direction of the upper cover.

摘要： In an optical pickup device, heat conduction from a semiconductor laser to a pickup case is to be increased, thereby to prevent the semiconductor laser from deteriorating in performance, being reduced in durability and in committing erroneous actions, and to improve its reliability. An optical pickup device comprises a semiconductor laser for recording or playing back information onto or from an optical disk, a laser drive circuit to control the driving of the semiconductor laser, a pickup case for mounting the semiconductor laser and the laser drive circuit, and a signal transmitting flexible substrate for transmitting signals and the like to the semiconductor laser. To this optical pickup device is added a heat conducting flexible member for thermally connecting the semiconductor laser and the pickup case.

摘要： Provided is a reliable optical pick-up which can prevent deterioration of a performance of a component, shortening of a service life or malfunctioning due to heat generation of an laser driver IC, wherein a metallic pattern is provided on a flexible printed board, having an area wider than the external shape of the laser driver IC and having an exposed outer surface, and made of the same material as that of a wiring pattern. It is preferable to bent the flexible printed board in a mounting part for the laser driver IC so that the metallic pattern is faced to and superposed with a surface of the flexible printed board on the side remote from the surface on which the laser driver IC is mounted.
