Abstract:
An operating apparatus, comprising:(a) press-operational operation elements; (b) pressure sensitive detector elements, each one associated with one of the press-operational operation elements, for providing analog signals corresponding to press-operations performed on said operation elements, each analog signal having associated therewith an output-level range; (c) a level divider for dividing the output-level range of each one of the analog signals according to individual divisional output levels and for providing output analog signals by converting an output level of each analog signal to one of the individual divisional output levels; (d) an analog-digital (A-D) converter for converting, the output analog signals to digital signals corresponding to the individual divisional output levels; and (e) a level corrector circuit for 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.
