Abstract

PURPOSE:To accurately detect the leading edge of a form by providing an optically white part in the visual field of a photoelectric transducer and providing an optically black part in this optically white part and detecting the point of the change from the black part to the white part. CONSTITUTION:A white peak holding means 15 which holds the white peak of the output from a photoelectric transducer 63 and a binarizing means 16 which compares the held white peak with the output from the photoelectric transducer 63 to binarize the output are provided, and an optically white part 20 and an optically black part 21 in this part 20 are provided on a carrying path 12 of a form 11 in the visual field of the photoelectric transducer 63. Scanning is performed without inserting the form to the carrying path to use points of the change from the optically black part to the optically white part as noticed points. The point of the change from the optically black part to the optically white part out of noticed points is regarded as the leading edge of the form at the time of insertion of the form to the carrying path. Thus, the leading edge of the form is accurately detected.
