Title: Detecting device of set error of slip
Inventor: MATSUDA SHINJI
IPC: G06K13/063
Filed: 1981-03-09
Abstract: PURPOSE:To reduce readout rejections and character, segment rejections in OCR, by accurately detecting even slight inclination, of a slip. CONSTITUTION:A reading head 4 outputs video signals while it receives reflected lights from a carrying path 1 or a slip 2. The reading head 4 moves in the direction normal to the carrying direction of the slip 2 along a rail 5. A head detector 6 outputs a head detect signal when the reading head 4 passes a reference point 7. Since the reflection factors of the carrying path 1 and the slip 2 are different from each other, when the reading head 4 moves from the carrying path 1 to the slip 2 and from the slip 2 to the carrying path 1, the video signal changes. When an edge detecting circuit detects the change in the video signal, the circuit sets a flip-flop.
