PROBLEM TO BE SOLVED: To enable to monitor output from a light receiving means in the case of comprising a two-dimensional light receiving element. SOLUTION: In a sensor 10, a slit beam is emitted to a detection region by a light projecting means 11, and its reflected light is received at a CCD 20, being a light receiving element. Distance-related information is computed on the basis of the peak location of the reflected light from the CCD 20. Images of the CCD 20 can be outputted from a video output terminal 27, and an image displaying means is connected to the terminal 27 at the time of adjustments. In this way, it is possible to verify sensitivity and mounting locations from monitor images.
