Claims

[Claims for Utility Model Registration] A light receiver used in an identification-type defect detection device that scans a translucent plate material running in the length direction with a light spot in the width direction to detect defects present in the translucent plate material. a first light-receiving section, which is formed by arranging a large number of optical fibers and constitutes an elongated light-receiving surface that receives the transmitted light; a second light-receiving section having an elongated light-receiving surface that receives paraxial transmitted light; a first light-diffusing section provided in front of the light-receiving surface of the first light-receiving section; a second light-diffusing section provided on the front surface of the light-receiving surface; a light-shielding partition between the first light-receiving section and the first light-diffusing section; and the second light-receiving section and the second light-diffusing section. A light receiver for an identification type defect detection device, comprising: a plate.
