Abstract
A fader device includes a conductive shaft, a conductive moving body, and a conductive portion. The conductive moving body is movable in the longitudinal direction of the shaft and includes a gap between it and the conductive shaft. The conductive portion brings the shaft and the moving body into electrical continuity. A signal generation portion generates a touch sense signal. A detection portion detects contact with the conductive moving body based on a signal output according to a capacitance generated between the conductive shaft and the conductive moving body in response to the touch sense signal.
