ABSTRACT:
In a distance measuring device which has a semiconductor position sensor or the like employed as a light receiving element and which produces two different signals corresponding to the incident angles of a light coming from an object, the signals from the light receiving element are supplied, one after another, to a dual-slope type integrator such as a Miller integrator. A length of time required for reverse integration of the dual-slope type integrator is measured. Distance to the object is computed on the basis of the measured time.
