Abstract
A reflection-type photoelectric switching apparatus for providing an electric switching signal indicating existance information of an object to be detected thereby comprising a light projecting device for projecting a beam of light to the object, a light receiving photoelectric device arranged in side-by-side relation with the light projecting device for receiving a reflected light from the object, an optical axis adjusting means which is controllable from outside of housing of the apparatus for adjusting the optical axes of the light projecting and receiving devices, and optical members which allow both the light beam from the projecting device and the light beam to be incident on the receiving device to pass within a predetermined light path so that the two light beams will be crossed in a desired detection field, the distance from the apparatus to the desired detection field being continuously variable by the optical axis adjusting means.
