Provided is a numerical value input apparatus that includes: an operation input unit that expresses numerical values of a plurality of digits by providing a plurality of numerical value setting operation units for each digit; with each of the plurality of numerical value setting operation units being biased to a side that is an initial state; and also includes a signal generation unit that, in a case in which an input confirmation key provided separately from the numerical value setting operation units is operated, confirms a numerical value that reflects the state of the numerical value setting operation units for each digit when the input confirmation key is operated, and converts the numerical value into an electric signal.
