    摘要： PROBLEM TO BE SOLVED: To perform stable position detection even under the condition that transmission efficiency of a light detection sensor including a photo-transistor and photointerrupter changes.SOLUTION: This unit comprises: a lens drive unit in which a lens is stored; a motor which moves the lens drive unit in an optical axis direction; a motor driving part which drives the motor for spherical aberration correction; a light-emitting device which generates light; a photo detector which outputs a current according to the amount of incident light from the light-emitting device; and a light-detection sensor which limits the amount of incident light falling upon the photo detector from the light-emitting device based on the position of the lens drive unit. A resistor which is connected to the photo detector and in which a current flows, is also included. A voltage applied on the resistor (analog voltage) is normalized (normal voltage), based on which a control signal is output to the motor drive to stop the motor.

    摘要： PROBLEM TO BE SOLVED: To provide an optical pickup device equipped with a short-circuiting means which prevents an electrostatic breakdown of a light emission chip to emit a laser beam, and which does not damage a substrate connected with the light emission chip, and to provide a method for manufacturing the same.SOLUTION: Wiring 22A and wiring 22B are arranged on an upper face of a base material 21, and a short-circuiting part 24A to provisionally short-circuit both of them is arranged on a region held between both of them on a circuit substrate 15A. Further, the short-circuiting part 24A includes a through-hole 34A continuing to the wiring 22A and a through-hole 34B continuing to the wiring 22B. The through-hole 34A is constructed with a plating film covering an inner wall of a penetrating hole penetrating the base material 21 with a circular shape, and formed of copper etc. Similarly, the through-hole 34B is also constructed with a plating film covering an inner wall of a penetrating hole penetrating the base material 21. When both the wiring parts are to be short-circuited, a short-circuiting pin 38 composed of a conductive resin etc. is inserted into the through-hole.
