Patent ID: 7428192

Claim:
An optical pickup device comprising: a semiconductor laser for emitting a laser beam for playing back or recording information from or onto an optical disk; a laser drive circuit, comprising a laser drive IC, for controlling the driving of said semiconductor laser; a metallic pickup case to be mounted with said semiconductor laser and said laser drive circuit; a signal transmitting flexible substrate for transmitting signals and the like from said laser drive circuit to said semiconductor laser; and a heat conducting flexible member for thermo-conductively connecting said semiconductor laser and said metallic pickup case, wherein said semiconductor laser and said laser drive circuit are mounted on said metallic pickup case, arranged close to each other and connected via said signal transmitting flexible substrate, wherein said heat conducting flexible member is formed of a heat conducting flexible substrate extending from said signal transmitting flexible substrate in a direction away from said laser drive circuit and thermally connected to said metallic pickup case by way of a wiring pattern of said heat conducting flexible substrate, said wiring pattern of said heat conducting flexible substrate being thermally separated from a wiring pattern of said signal transmitting flexible substrate.
