Abstract
PURPOSE: To simplify a recognition device, and to eliminate the bad influence of the variation in scanning rate of a tag on reading by generating a data latch synchronous pulse by detecting change points (color change points) of the output signal of a color sensor.
CONSTITUTION: On color tage 1, color [A] is made to correspond to [1], and color [B] is to correspond to [0]; when [1] or [0] continues, color [C] is inserted being odd-numbered, so that respective colors will be assigned while the continuation of one color is prevented. By letting tag reader 2 scan on tag 1, signals equivalent to colors A to C are outputted to output terminals 5 to 7 by way of glass fiber 3 and color sensor 4, and by data signal generator 8, output signal 10 is turned on when color A singal is inputted and line 10 is turned off when color B signal. On the other hand, when one of color signal A to C is inputted, data latch pulse generator 9 outputs a pulse to output line 11 after a fixed delay time and data processor 12 latches the signal of input line 10 at the time of pulse generation from incoming line 11, thereby performing a series of data processes.
