PURPOSE:To use an optical pickup device main body in common and to easily mount/dismount a pre-amplifier circuit board by the pre-amplifier circuit board on a connector on a laser diode output control circuit board mounted via a flexible board for transmitting the output signal of an optical detector via the connector on the pre-amplifier circuit board. CONSTITUTION:The pre-amplifier circuit board 2 is attached on the optical pickup device main body 1, and the one end of the flexible board 4 for transmitting the output signal of the optical detector is mounted on the device main body 1. The laser diode output control circuit board 5 is mounted on the other end of the board 4, and the connectors 6a and 6b are provided on the board 4. And the optical pickup device main body 1 is assembled only by a stock item, and the circuit board 2 is mounted only on a kind of device corresponding to necessity at the final assembling process, and the fixing on the circuit board 2 is easily performed by the connectors 6a and 6b mutually, then, the unification of the device can be attained. |
