項記載の光学式ピツクアツプの板ばね固定機構。[Claims for Utility Model Registration] (1) In an optical pickup in which a movable member that operates together with an objective lens is movably supported by a flat leaf spring, the upper and lower surfaces of the leaf spring are vibration absorbing materials. The leaf spring is placed on the movable member via the vibration absorbing material on one side, and the support projection provided on the movable member extends over the leaf spring without touching the leaf spring. and
A leaf spring fixing mechanism for an optical pick-up, characterized in that a vibration absorbing material installed on the upper surface of the leaf spring is supported with respect to a movable member by the support protrusion. (2) The vibration absorbing material is coated to cover the entire surface of the leaf spring.Claim No. 1 of the utility model registration claim
The leaf spring fixing mechanism for the optical pick-up described in .
