Abstract
PURPOSE: To economize the check system, by grouping the input leads to perform checking.
CONSTITUTION: When incoming signals are A,B and C code, AO to A7,BO to B7 and CO to C7 are taken as the input to each code. The exclusive logical sum elements 10 to 13,20 to 23, and 30 to 33 check individual code, and output the error signal E when either of the check circuits a,b,c is 1. With this constitution, as to the code A, the inspection objective of signal is grouped into two groups of AO,A1,A2 and A4,A7. As to the code A, constitution is made that all are treated as error other than one signal to A0,A1,A2 and one signal A4,A7 (a), two signals at A0,A1,A2 (b), and signal for the both A4 and A7 (c). Further, the similar check is made for the codes B and C, and as the result of check for either of the codes, if the output of individual check circuit is 1, the error signal E is outputted.
