Abstract

First, second, and third lead-out conductors connected to the electrodes of two types of laser emission devices of an optical pickup are led out on a lead-out board. First connection areas short-circuit by solder at a portion of opposing parts of any two adjacent lead-out conductors of the first, second, and third lead-out conductors in the width direction crossing the longitudinal direction and open the short circuit, and second connection areas short-circuit by solder at a portion of opposing parts of the other pair of two adjacent lead-out conductors of the first, second, and third lead-out conductors in the width direction crossing the longitudinal direction and open the short circuit. The first connection areas and the second connection areas are arranged in a staggered pattern in the longitudinal direction of the lead-out conductors.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Japanese Patent Application No. 2004-24275 filed on January 30, 2004, which is hereby incorporated by reference. field of invention [0003] The present invention relates to an optical disc device. Background technique [0004] A laser radiation device of an optical pickup used in an optical disc device may be damaged or destroyed during assembly of the optical pickup and the optical disc device due to static electricity generated by a worker performing an assembly operation of the optical disc device. Therefore, in this assembly process, in order to protect the laser irradiating device from static electricity, the lead wires respectively connected to the anode and the cathode of the laser irradiating device are connected on the lead plate by connecting them with soldering in a state where they are not connected to the circuit. short circuit. [0005] In addition, in order to cau...
