Patent ID: 7475412

Claim:
An optical disk drive apparatus comprising: an optical pick-up device body having at least a semiconductor chip component mounted thereon; an optical module having an optical system; a case for optical pick-up adapted to be reciprocally traveled linearly in a horizontal direction between an inner periphery and an outer periphery of an optical disk; said optical pick-up device and said optical module being provided at said case; a drive having a drive apparatus for rotating the optical disk and circuit; and a flexible substrate for connecting said optical pick-up device body and the drive; wherein a first flexible substrate is fixed to an upper surface of said optical pick-up device provided at said case for optical pick-up; wiring conductors on a first connection end portion of said first flexible substrate fixed to said upper surface of said optical pick-up device, and wiring conductors on a second connection end portion of a second flexible substrate produced separately from said first flexible substrate are overlapped and aligned with one another at a region adjacent to an end portion of the case for optical pick-up on the case for optical pick-up, and connected to one another through joining material; and a connection section in which said wiring conductors of said first connection end portion and said wiring conductors of said second connection end portion are connected to each other at the region adjacent to the end portion of the case for optical pick-up on the case for optical pick-up is pressed down by a cover attached to said optical pick-up case for protecting said optical pick-up device body.
