<p>PROBLEM TO BE SOLVED: To quickly set a setting value without causing a steep rise of a manufacturing cost or deterioration in visibility of a display screen.SOLUTION: When an up operation for changing the M-th digit in a number in N figures is executed, it is determined whether or not the number in N figures can be changed to a number equal to or less than an upper limit by changing the M-th digit to a larger number by one (step 26a). In a case where the number in N figures can be changed to a number equal to or less than the upper limit, first number change processing for changing the M-th digit to a larger number by one is executed (step 27). In a case where it cannot be changed to a number equal to or less than the upper limit, second number change processing for changing the number in N figures to the upper limit is executed (steps 28a-31a) and number restoration processing is executed for restoring the number in N figures to a number for which the second number change processing has not been executed, when a down operation for changing the M-th digit is executed after the second number change processing (processing at the time of flag set 40).</p> |
