することを特徴とするシート材の欠陥処理装置。[Claims for Utility Model Registration] A light source, an inspection cylinder, a synchronization device, a camera, and an image processing device, which irradiates light from the light source onto a traveling sheet material, and images the sheet material using reflected or transmitted light. In a defect detection device that captures image information as a two-dimensional image using the camera, and detects defects in the sheet material from the image using the image processing device in real time, the image processing device 11 captures image information in synchronization with a synchronization pulse. an image signal latch circuit 61 that processes the image signal from the latch circuit, a differential filter processing circuit 62 that performs differential filter processing on the image signal from the latch circuit, a binarization processing circuit 63 that performs binarization processing on the image signal from the differential filter circuit, and a logical filter processing circuit 64 that performs logical filter processing to remove noise from the image signal from the binarization processing circuit; and a defect length that calculates the length of a connected component of a defect from the image signal from the logical filter processing circuit. An arithmetic circuit 67 and a defect length memory 68 that stores a reference value as a defect length compare the image signal from the defect length arithmetic circuit with the reference length image signal from the defect length memory 68 to determine the presence or absence of a defect. A sheet material defect processing device characterized by comprising a comparison circuit 69.
