Operating apparatus and signal-output-modulating method for the same

A signal-output modulating method for an operating apparatus including pressure sensitive detector elements for providing analog signals corresponding to press-operations performed on the operation elements, the method comprising:

• (a) dividing an output-level range of the analog signals into individual divisional output levels;
• (b) providing output analog signals by converting output levels of the analog signals to one of the individual divisional output levels;
• (c) converting the output analog signals to digital signals;
• and
• (d) shifting levels of the digital signals according to a predetermined corresponding reference level, so that the levels of the digital signals are within a specific output-level range.
