Abstract

Provided is an optical pickup device with which a short-circuit can be released from above and below. The optical pickup device (15) is provided with: a housing (15B) formed by ejecting a resin material in a prescribed shape; an actuator (15D) that is positioned on the top surface of the housing (15B) so as to hold an objective lens (17); a circuit board (15A) that is fixed to the main surface of the housing (15B); and a connector (15C) that is attached to the top surface of the circuit board (15A). A second short-circuit part (25) and a first short-circuit part (24) are disposed on the top surface and the bottom surface of the circuit board (15A), and a built-in light-emitting chip is protected from electrostatic discharge damage by shorting either one of the short-circuit parts.

Description

technical field [0001] The present invention relates to an optical pickup device having a short-circuit portion for preventing destruction of a light-emitting chip by static electricity. Furthermore, the present invention relates to an optical disc device having the above-mentioned optical pickup device and a method of manufacturing the same. Background technique [0002] The light-emitting chip of the optical pickup used in the optical disc device may be degraded or damaged by static electricity received from workers performing the process during the assembly process of the optical pickup or the optical disc device. [0003] Therefore, in this assembly process, in order to protect the light-emitting chip from static electricity, solder is used on the lead-out substrate to connect and lead out the anode electrode of the light-emitting chip in a state not connected to the circuit. The wiring is connected to the wiring that is connected to the cathode electrode and drawn out,...
