Abstract
PURPOSE: To attain reading with high accuracy by discriminating the validity and the invalidity of data in a work number discriminating circuit based on the output signal of plural phototransistors and latching the valid data of the work number read based on the discriminated result in a latch circuit.
CONSTITUTION: A pulse driving circuit 8 for lighting the pulse of plural light emitting diodes 4 based on a first timing signal outputted from a timing generating circuit 7, the work number discriminating circuit 9, 10 for discriminating the validity and the invalidity of the data of the work number based on the output signal of the plural phototransistors 5 and the latch circuit 11 for latching the data of the work number according to a second timing signal outputted by a timing generating circuit 7 are disposed. Thereby, the light emitting strength of the light emitting diode can be increased with a little power, the validity and the invlidity of the read data are discriminated to output only the data of the correct work number to as the valid data.
