Abstract:
An apparatus for detecting a position of a movable optical pickup head, comprising:a first electrically conductive member;a second electrically conductive member provided on a body of the optical pickup head, the second electrically conductive member moving into contact with the first electrically conductive member when the optical pickup head reaches a predetermined limit position, the second electrically conductive member moving out of contact with the first electrically conductive member when the optical pickup head separates from the predetermined limit position;a microcomputer including first and second terminals, the first terminal being grounded;means for electrically connecting the first electrically conductive member to the second terminal of the microcomputer; andmeans for grounding the second electrically conductive member via the body of the optical pickup head;wherein the connecting means consists of a single wiring line and a 1-pin connector, the wiring line extending between the first electrically conductive member and the second terminal of the microcomputer, the 1-pin connector being interposed in the wiring line.
