The winder electronic counter circuit is composed of the photoelectric sensor circuit, shaping circuit, plus / minus identification circuit and four-digit counter circuit, and the circuit is shown as the chart. Photoelectric sensor circuit consists of resistors R1, R2, R8, R9 and optocouplers VLC1, VLC2. R1, R8 and VLC1 form the plus counting sensor circuit, and R2, R9 and VLC2 form the subtraction counting sensor circuit. Shaping circuit consists of D1 ~ D4 which are inside of six NOT gate Schmitt trigger integrated circuit IC1.
