Abstract

PURPOSE:To rediably detect the existence of a defect without being influenced by the cue or the variation in the condition of paper by integrating the output, which is generated by photo-electrically converting the transmitted or reflected light for each preset srea of an object to be detected, and by comparing the integrated output with a preset level.
