摘要： An optical pickup includes a diffraction element for causing diffraction in a reflection beam from a disc. This diffraction element is divided into two of first and second regions. On four light receiving elements are converged respectively a first reflection beam from a first region and a second reflection light from a second region. A switch performs switching-over between four output signals individually taken from four light receiving elements and three output signals in total taken out by adding together two output signals of four output signals.

摘要： A photoelectric conversion integrated circuit device for converting a light signal into a voltage signal has a photodiode that outputs a current in accordance with a light signal it receives, a current-to-voltage conversion circuit that outputs a voltage signal in accordance with a current signal it receives, and a test circuit that outputs a current and whose on/off state is controllable from the outside. At the output of the photodiode, two output terminals are provided, of which one is connected to the current-to-voltage conversion circuit and the other to the test circuit. This photoelectric conversion integrated circuit device allows a fault in the wiring between the photodiode and the current-to-voltage conversion circuit to be detected by feeding an input current to the current-to-voltage conversion circuit without shining light on the photodiode.

摘要： A photo diode is connected to an input terminal of an amplifier to which a feedback resistor is connected. An output current of this photo diode flows from the output terminal side of the amplifier through the feedback resistor. The output of the photo diode converted into a voltage is given to the output terminal side of the amplifier. The feedback resistor is formed by a P-type resistor region provided in an N-type resistor land of a semiconductor substrate. In order to apply an inverse bias to the PN junction between the resistor land and resistor region, the resistor land is connected to the output terminal of the amplifier.
