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

摘要

An operating apparatus and a signal-output modulating method therefor allow analogous operations to be implemented by use of press-operational operation elements that have conventionally been used for digital operations. In the operating apparatus, detecting elements are provided, each of which is formed of a resistant material and a conductive material. The detecting elements individually output analog signals corresponding to press-operations performed on the operation elements. Output-level range of an analog signal outputted from the detecting element is divided by a level divider into multiple levels, and an analog-digital (A-D) converter performs conversion thereof to an analog signal converted digital signals corresponding to the output levels. In addition, output levels of the individual digital signals outputted from the A-D converter are shifted by a level corrector 17 according to a predetermined corresponding reference, and the digital signals are thereby output.
