Abstract:
1. A dial controller comprising: a dial; a displacement converter for converting a rotational displacement caused by a rotation operation of the dial to an axial displacement of the dial along a rotation axis of the dial; a displacement detector for detecting and outputting information on a rotation angle of the dial based on a detection result of the axial displacement of the dial; a position indicator being disposed separately from the dial in an axially movable manner along the rotation axis of the dial; and a displacement conversion mechanism for converting the rotational displacement caused by the rotation operation of the dial to the axial displacement of the position indicator along the rotation axis in a course of transmission thereof, wherein the displacement detector detects a position of the position indicator along the rotation axis of the dial, the displacement detector outputs the rotation angle of the dial based on the detection result of the position of the position indicator, and the displacement detector includes a sliding electrical contact that is movable along the rotation axis of the dial in association with a movement of the position indicator and a variable resistor that is variably divided by the sliding electrical contact in terms of a resistance value of the variable resistor.
