Abstract

It is an object of the present invention to allow both a digital operation and an analog operation by using pressing operation continuously.An operating device has detecting elements (e.g., pressure-sensitive elements (12)) for outputting analog signals according to pressing operations of operators (11), and is configured such that analog signals output from the detecting elements are subjected to level dividing by a level dividing unit (15) and converted into multi-bit digital signals corresponding to the output levels thereof by an A/D converting unit (16), and is also configured so as to output single-bit digital signals according to change in analog signals output from the detecting element. A switching unit (18) outputs one or the other of the multi-bit digital signals and single-bit digital signals.
