Patent ID: 7592585

Claim:
An optical pickup in which a printed-wiring main substrate is mounted on one surface of a slide base movable back-and-forth in the radial direction of a disk, while a standing frame is formed integrally on a second surface of said slide base, opposite said one surface, a light source element and reading and light-detecting elements being positioned and fixed to said standing frame, and end portions of flexible flat cables extending from said respective elements are soldered to said main substrate at solder connections, where a laser beam from said light source element is adapted to be applied to the disk and the reflected light is adapted to be received at said reading element to read information recorded on the disk as well as to detect the intensity of the laser beam through said light-detecting element, wherein said slide base comprises: a planar portion spaced from and parallel to said main substrate; an insertion opening in said planar portion through which extends an end portion of one of said cables extending from said light source element to a solder connection on said main substrate; a first extended portion integral with said planar portion and extending from a peripheral edge of said insertion opening, at an angle with said planar portion and toward said main substrate, said first extended portion having a distal end face spaced from said main substrate to define a first gap therebetween which is slightly greater than the thickness of said one cable, said first cable extending through said first gap; and a second extended portion integral with and extending from an outer peripheral edge of said planar portion of said slide base at an angle with said planar portion and toward said main substrate, said second extended portion having a distal end face spaced from said main substrate to define a second gap therebetween slightly greater than the thickness of another of said cables, said another cable extending through said second gap.
