PROBLEM TO BE SOLVED: To provide a controller which can deal with analog input of many patterns.SOLUTION: A controller has a voltage signal as an input signal. A positive pole side path 51 is provided with a first resistor 21, and a path 53 across the positive pole side path 51 and a negative pole side path 52 is provided with a second resistor 22. The first resistor 21 and the second resistor 22 function as voltage dividing resistors, and voltage of the voltage signal is lowered by half and inputted to a microcomputer 10. The microcomputer 10 preliminarily holds voltage of an input voltage pattern and a read map corresponding to a rate of voltage of the input voltage pattern after lowered by the first resistor 21 and the second resistor 22. The map is selected by a first changeover switch 13 and a second changeover switch 14 of the microcomputer 10. |
