Abstract

PURPOSE:To simplify a fitting work and to improve reliability by providing many kinds of optical components from the same direction to a head. CONSTITUTION:A collimator unit 10 having a semiconductor laser and a collimator lens barrel is fitted to the main body of an optical head 12 from a Z direction, and it is fixed with two screws 26 through a collimator pressing board 16. Polarizing beam splitters 3, 6 and 7 and a converging lens barrel 5 are also fitted to the optical head 12 from the Z direction, and the converging lens tube 5 is fixed by fitting a converging lens barrel pressing board 18 from the Z direction. In such a way, a constitution is so made that the many kinds of the optical components provided on the optical head 12 can be fitted from the same direction. Thus, the components can be fitted with good accuracy and easily, and the reliability of the work can be improved.
