Abstract: PURPOSE:To enable detection of position and speed of a moving body with high resolution by a simple operation by a method wherein a device generating a pulse in every movement for a prescribed minute distance on the basis of a sine-wave original signal of a movement detector is constructed only of an analog circuit. CONSTITUTION:A detecting element 1 of a voltage proportional to a moving speed outputs an AC voltage proportional to the moving speed of a moving body and an AC zero-value signal and inputs them to positive and negative bias voltage impression circuits 19, 20 and 21, 22. Voltage control oscillators 25, 26 and 27, 28 receive bias outputs of the voltage proportional to the moving speed and bias outputs of the zero- value signal of the circuits 19, 20 and 21, 22 respectively and generate pulses. Normal- direction movement position counters 31 and 32 and reverse-direction movement position counters 33 and 34 receive the pulses oscillated by the oscillators 25, 26 and 27, 28 and a movement direction signal delivered from the detecting element 1 and count the pulses for each moving direction shown by the moving direction signal. While transmitting start and end signals of counting to each of the counters 31 to 34, CPU 35 receives an output of each counter as an input and computes the position of the moving body.

The photodetecting sensor 2 detects the quantity of received light at this time and transmits the information to the main storage device 6. Above- mentioned operations are repeated and the angle with the least reflected light from the display screen looking from the operator side is decided. Thus, the visibility to the display screen for the operator is improved and misoperations can be reduced.
