PROBLEM TO BE SOLVED: To provide a chattering elimination circuit for eliminating chattering of a plurality of input signals by means of chattering elimination circuits less than the number of signals to be inputted.SOLUTION: The chattering elimination circuit includes: an input signal detection section 10 to which parallel input signals S1-1, S1-2, S2-1 and S2-2 are inputted; chattering elimination sections 30 and 31 for eliminating the chattering of the signals to be inputted; and an allocation control section for allocating input signals C1-1, C1-2, C2-1 and C2-2 to the chattering elimination sections 30 and 31 for outputting, and separating digital signal D1 and D2 which are returned from the chattering elimination sections 30 and 31 after eliminating the chattering correspondingly to the parallel input signals. |
