Abstract
PURPOSE: To find and display in a short time an electronic circuit printed board which is out of order by providing two or more electronic circuit printed boards of the same function and comparing their output when the same data are input to them.
CONSTITUTION: An input data memory 4 gives a set of data signals to three boards 1, 2 and 3. By so doing, the boards 1, 2 and 3 generate patterns respectively, and as the result, the boards 1, 2 and 3 output signals A1, A2 and A3 respectively. These output signals are input to exclusive OR circuits 6, 7 and 8, and are compared if these output signls are the same or not, and when they differ, it is determined that some of the boards are defective. These output data are displayed and recorded by a displaying and recording part 9.
