Abstract

PURPOSE: To ensure decision for the normal or abnormal page code output by giving a comparison to the output of the independent right and left page detection parts and then giving the switch to the output via the coincidence signal in case the page codes are identical between the both detection parts.
CONSTITUTION: The output of key switch group 1 is delivered outside through switch code encoder 2 and driver 3, and the output of left page detection part 4 enters page encoder 5 to be then supplied to comparator part 9 along with the output of right page detection part 8. And the coincidence signal delivered when the coincidence is secured between the right and left page codes is supplied to gate part 10 from part 9 along with the signal of encoder 5 to be then delivered outside. Here if the output is identical between parts 4 and 8, the output is switched by the coincidence signal. Thus the decision can be given whether the page code output is normal or not.
