PROBLEM TO BE SOLVED: To provide a stable output, and to reduce a cost, since only a slide rheostat of high resistance is used by providing a constant-current generating means for outputting variable constant currents of high resolution and low resolution. SOLUTION: This current regulation circuit for regulating a current supplied to a thermosensitive sensor for outputting a voltage corresponding to a temperature has the first constant-current generating means for outputting the variable constant current of high resolution, and the second constant-current generating means outputting the variable constant current of low resolution, and the currents output from the first and second constant-current generating means are added to be supplied to the thermo-sensitive sensor. |
