Abstract:
An optical pickup device, comprising:a light source for irradiating light onto an optical disk, a light-receiving means for receiving light reflected by the optical disk and converting received optical signals into electric signals, a high-frequency superposition circuit for driving the light source by using a high-frequency superposition method, a flexible printed circuit board (referred to as â€œFPCâ€ ) including a circuit and a connector for input and output of signals for driving said light source and the high-frequency superposition circuit as well as signals from said light-receiving means, and a reinforcing plate with a conductive plated surface being formed on a rear surface thereof, wherein: said high-frequency superposition circuit is mounted on said FPC, said FPC is further formed with a grounding (referred to as â€œGNDâ€ ) pattern and a projecting portion projecting outward of the FPC, and with a conductive plated pattern being formed on a surface of the projecting portion to be conductive with the GND pattern, and a rear surface of said FPC is adhered to surfaces of said reinforcing plate, the projecting portion of the FPC is bent, and the conductive plated pattern is electrically connected to the conductive plated surface of said reinforcing plate.
