ABSTRACT:
An active type distance detecting device wherein either a light emitting element or a light receiving element is operated to scan by a scanning means. A signal for driving the scanning means is interposed between pulse signals for causing the light emitting element to emit flickering light so that the former signal may not overlap with the latter pulse signals in order to reduce fluctuations of a load electric current.
