PROBLEM TO BE SOLVED: To precisely determine an operation position by an operation body, in an input device provided with detecting means for obtaining a binary output in a plurality of division areas. SOLUTION: This input device 1 is arrayed annularly with the plurality of division areas A-H, and includes detecting means 6A-6H for outputting an ON signal or OFF signal in the respective division areas. A reference coefficient is set in a reference division area, using the division area positioned with the detecting means obtaining the detection signal (ON) at first as the reference division area, positive coefficients are allocated sequentially clockwise from the reference coefficient, and negative coefficients are allocated sequentially anti-clockwise therefrom. A value d=s/m is computed based on the sum of the coefficients in the division areas with the detecting means obtaining the detection signal (ON) belonging thereto, and the number of the detecting means 6 obtaining the detection signal (ON), when contacting with the operation body, and the value d is determined as the operation position by the operation body.
