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