してなる光学ヘッドのハーフミラ−固定装置。Holding a focusing lens, a photoelectric conversion element, and a light source in a storage body,
The light beam from the light source is irradiated onto the information medium through the half mirror 1 focusing lens, and the reflected beam from the information medium is irradiated onto the photoelectric conversion element through the focusing lens and the 1st half mirror, thereby converting the information into optical information. In an optical head for reproducing data, the half mirror is locked to a support body having a protruding arm formed on the side thereof, and the protruding arm is guided by a guide groove formed in an insertion hole of the half mirror of the storage body. A support body is inserted into the insertion hole, the half mirror is brought into contact with an inclined part formed at the bottom of the insertion hole, a spring member that is engaged with the storage body is brought into elastic contact with the support body, and the half mirror is moved into the inclined part. A half mirror fixing device for an optical head, which is pressed against the part.
