Apparatus for fixing half mirror of optical pickup

An apparatus for fixing a half mirror of an optical pickup, said half mirror being disposed in a light passing hole of a pickup body in such a way as to be in an inclined state, in which a pair of left-hand-side and right-hand-side concave grooves communicating with an opening portion of a light passing hole are respectively formed in both side portions of an inner surface facing an innermost edge of said half mirror, among four inner surfaces of said light passing hole, and in which both side edge portions of a fastening device body of a fastening device constituted by a leaf spring are inserted into and passed through both said concave grooves, respectively, said apparatus comprising:

• a pair of left-hand-side and right-hand-side presser plate portions, which are respectively extended from both side edge portions of said fastening device body and caused to elastically abut against a surface of said half mirror;
• a connecting plate portion, provided between tip ends of both said presser plate portions, for integrally connecting both said presser plate portions to each other, said connecting plate portion being bent so that a transverse section thereof is nearly-L-shaped, a nearly-L-shaped recess part of said connecting plate portion being engaged with an opening-portion-side edge of said half mirror;
• a pair of left-hand-side and right-hand-side engaging claw portions respectively bent from both side edge portions of said fastening device body in a direction opposite to a direction, in which said left-hand-side and right-hand-side presser plate portions are extended, to thereby engage with said inner surface;
• and
• a catch piece portion bent from a central portion of said fastening device body and extended to a peripheral edge of said opening portion of said light passing hole.
