Abstract
A position detecting circuit for use in an apparatus for performing position control such as an original reading apparatus is disclosed. In the position detecting circuit according to the present invention, emitted light from a light emitting device is received by a CCD image sensor and a peak value of the output signal waveform of the CCD image sensor is detected. Then, the photosensing position of the CCD image sensor is identified according to the position of the peak value in the output signal waveform. The position of a moving member is determined by the photosensing position of the CCD image sensor, whereby the position detecting system is simplified in structure and enhanced in detecting accuracy.
