摘要	An optical pick-up is arranged to detect information recorded on an optical disk by causing laser light projected onto and reflected from a signal surface of the optical disk disposed within an optical system and the laser light is received by a light receiving element provided in the optical system. The optical pick-up is mounted with a laser diode unit which includes a metallic substrate, a laser diode, a photo-diode, a current feeding lead portion to the laser diode and a current output lead portion which forms the photo-diode, respectively disposed at one side face in the direction of thickness of the metallic substrate for emitting the laser light. The laser diode unit is positioned and fixed at a predetermined position of the optical system through a mounting member. The mounting of the laser diode unit includes setting the other side face in the direction of thickness of the substrate and the mounting member in a desired positional relation for contact with each other as a result, a plurality of contact places therebetween may be simultaneously welded by laser light for combining the laser diode unit and the optical pick-up into one unit.
其他摘要	设置光学拾取器以通过使激光投射到设置在光学系统内的光盘的信号表面上并从其反射来检测记录在光盘上的信息，并且激光由设置在光学系统中的光接收元件接收。光学系统。光学拾取器安装有激光二极管单元，该激光二极管单元包括金属基板，激光二极管，光电二极管，激光二极管的电流馈送引线部分和形成光电二极管的电流输出引线部分。设置在金属基板的厚度方向上的一个侧面上，用于发射激光。激光二极管单元通过安装构件定位并固定在光学系统的预定位置。激光二极管单元的安装包括将基板厚度方向上的另一侧面和安装构件设置成所需的位置关系，从而彼此接触，其间的多个接触位置可以同时焊接在一起。用于将激光二极管单元和光学拾取器组合成一个单元的激光。
