The present invention relates to an optical pickup actuator which includes a plurality of objective lenses for converging a light on an optical recording medium, a lens holder for holding the objective lenses, a suspension wire for holding the lens holder and projections provided at the lens holder, wherein the projections are provided at the periphery of the objective lens and at least one of the projections is provided on the upstream side of the insertion direction of the optical recording medium. A slope for guiding the optical recording medium upward at the time of inserting the optical recording medium is provided on the side surface of each of the projections. Thus, even when the optical recording medium is inserted so as to slide on the upper surface of a pickup cover, the end portion of the outer periphery of the optical recording medium contacts with the slope provided at the projection and slides to thereby push down the optical pickup actuator in the elevational direction. Thus, since there does not arise a force in the bending direction of the suspension wire, the deformation of the suspension wires can be prevented.

Optical pickup actuator and optical disc driver using the same

An optical disk unit includes a tray for supporting an optical disk thereon, a body for receiving the tray therein, a first board provided at the body, a second board provided at the tray, and a wiring board (flexible board) electrically connecting the first board and the second board together. The wiring board (flexible board) has a number N of bent portions, the wiring board being bent at the number N of the bent portions of the wiring board, such that the wiring board is superposed in (N+1) layers where N is an integer equal to or greater than 1, and an area of the (N+1)-layer superposed portion is changed according to an amount of drawing-out of the tray.
