Abstract

PURPOSE: To make a light receiving element hardly influenced by diffused external light by turning the light receiving element to a light receiving angle not to be orthogonally crossed with an object passing direction or turning it to a light receiving position shifted from the object passing direction center position of an object passing route to the passing direction. CONSTITUTION: A light emitting diode 25 directing a phototransistor 26 is arranged so as not to make an optical axis C be orthogonally crossed with the passing direction A of a spherical body 22 and the axial line of a circular hole 28 is formed so as to match with the optical axis C. Thus, the light receiving angle of the phototransistor 26 is set so as not to be orthogonally crossed with the passing direction A of the spherical body 22. Also, the optical axis C is set so as not to be passed through the plane center 01 of the passing route 24. Even when the diffused external, light B intrudes the passing route 24, the phototransistor 26 does not receive the diffused external light B from the light receiving angle and the case that the passing of the spherical body 22 is not detected even when the spherical body 22 is passed through the passing route 24 is eliminated.
