Title: Disk reproducing device
Inventor: WASHIYAMA TORU
IPC: G11B7/085
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To prevent the phenomenon of flexible board rolling-in by an optical pickup during carrying of the optical pickup. SOLUTION: An FPC(flexible printed circuit) 9 from a U-shaped folded part 9a to a fixed board is arranged close to and along the inner wall surface of a mechanical cover 11. Since the mechanical cover 11 is vibrated integrally with an optical pickup 8 and a mechanical chassis 12, distortion is prevented in the FPC 9 arranged close to and along the inner wall surface of the mechanical cover 11. Also, since no fluctuation occurs in a distance between the optical pickup 8 and the mechanical cover 11 during vibration, the probability of preventing contact with the FPC 9 during the carrying of the optical pickup 8 is high. Thus, the phenomenon of the rolling-in of the FPC 9 by the optical pickup 8 is suppressed.  Further, by fixing the FPC 9 from the folded part 9a to the fixed board to the mechanical chassis 11, assembling efficiency and disassembling efficiency during maintenance are increased.
