Patent ID: 7220133

Claim:
An optical disc apparatus using a flexible printed-wiring board to interconnect an optical pickup and a circuit board having a signal-processing circuit, the apparatus comprising: a first member formed of a plate-shaped or sheet-shaped insulating material, the first member being disposed on the flexible printed-wiring board in close proximity thereto at the side of the circuit board that faces the optical pickup; and a second member having a protrusion in a face opposed to the circuit board or to the first member, the second member being disposed on a face of the first member and the protrusion being coupled to the circuit board in a planar region thereof, wherein the circuit board includes a connector with which the flexible printed-wiring board is electrically connected; the circuit board and the optical pickup are interconnected with each other by the flexible printed-wiring board folded back at an end of the circuit board; and the second member is adapted to press the flexible printed-wiring board against the face opposed to the first member, via the first member, and fix the flexible printed-wiring board to the circuit board.
