Abstract: PURPOSE: An area sensor is provided to reduce costs by introducing a rotative reflector reflecting light of a light emitting diode(LED) to a wide area, and to improve data processing speeds. CONSTITUTION: A laser diode(13) outputs light at regular intervals. A light emitting unit(10) includes a lens(14) focusing the light of the laser diode. A rotative reflector(20) reflects the light of the light emitting unit, to make the light reflected on a wide area of a subject(50). An amplifier(32) detects the light to amplify a current of a light receiving element(31). A synchronization detector(33) adjusts an outputted signal of the amplifier to an outputted signal of an oscillator(11) to output the signal. A comparator(34) compares a reference voltage with the outputted signal of the amplifier to output a compared result. Many light receiving units(30) have one-short oscillators(35), respectively. The one-short oscillators delay the signal of the comparator for a predetermined time. A first OR gate(41) applies OR operations to each signal of the light receiving units, and outputs many signals. A second OR gate(42) applies OR operations to the signals of the first OR gate, and outputs one signal. An encoder(43) is applied with the signals of the light receiving units, and codes the signals. A data processor/displayer(40) is applied with the signal of the second OR gate in an interrupt terminal, and stores the signals of the encoder in an internal memory when the applied signal has a high electric potential. The data processor/displayer has a micro controller(44) displaying the signals of the encoder in a displayer(45).
