Optical pickup device

摘要

An optical pickup device including a lead frame and a board attached to the lead frame is provided. The lead frame includes optical components, such as a laser diode and an optical element, which are disposed within a lead frame. A photo diode is mounted on the board to receive a beam transmitted through the optical element. The board is adjusted with respect to the lead frame using the beam before attached to the lead frame. An upper opening and a lower opening are formed on an upper side and a lower side of the lead frame, respectively. An optical element installation space formed within the lead frame and defined by an upper side walls and an optical element support. A hole is formed in a central portion of the optical element support and communicates with the optical element installation space and a photo diode installation space which is defined by the optical element support and a lower side wall of lead frame. The laser diode emitting the beam is mounted on a laser diode support which is formed adjacent to the optical element support in the optical element installation space. The optical element mounted on the optical element support is disposed within the optical element installation space to direct the laser beam emitted from the laser diode toward an optical medium through upper opening and to transmit the laser beam to the photo diode of the board.
