OPTICAL PICKUP ACTUATOR

PROBLEM TO BE SOLVED: To provide an optical pickup actuator in which an instant adhesive for sticking a coil for tracking control to a front wall plane of a lens holder can be prevented from flowing into a wire insertion hole. SOLUTION: Vertical ribs 1g in each of which a wire insertion hole 1i is perforated are formed at front ends of left and right side walls 1a of a lens holder 1 holding an objective lens 5 so that the front plane of the vertical rib becomes the same surface as the surface of a front wall 1b of the lens holder 1 to which the coil for tracking control is stuck, a tip part of a wire 4 is inserted and fixed to the wire insertion hole 1i and the lens holder 1 is supported, a convex stripe 11 obstructing flow of an adhesive is formed between the surface of the front wall 1b to which the coil for tracking control of the lens holder 1 is stuck and the wire insertion hole 1i of the vertical rib 1g. Flow of the adhesive is obstructed by the convex stripe 11 and flow-in to the wire insertion hole 1i is prevented. COPYRIGHT: (C)2008,JPO&INPIT
