Abstract: An input device includes: a first electrode including a reference potential electrode and two or more sets each including a transmission electrode and a reception electrode; and a second electrode that approaches and recedes from the two or more sets by rotating while facing the first electrode with a predetermined space being provided therebetween. The reference potential electrode faces at least a portion of the second electrode as a result of the second electrode approaching at least one set out of the two or more sets. A phase when a first set of first transmission and reception electrodes disposed in a first region approaches and recedes from the second electrode is different from a phase when a second set of second transmission and reception electrodes disposed in a second region approaches and recedes from the second electrode.

Abstract: An input device includes two fixed electrodes and an operating member. The two fixed electrodes is configured to be placed to overlap with specific line electrodes of a plurality of line electrodes . The operating member is movable with respect to the two fixed electrodes. The operating member is movable within a movable range including a plurality of click points. Electrical states of the two fixed electrodes change among a plurality of states in accordance with a movement of the operating member. A divisor of an integer N does not include 4, where the integer N is a total number of times of change in the electrical states of the at least two fixed electrodes when the operating member moves from one to a next one of adjacent two click points of the plurality of click points.

Abstract: An input device includes: a first electrode; a support body that supports the first electrode; a fixed body fixed above the support body; a second electrode; a movable body that holds the second electrode in a state where the second electrode faces the first electrode with a predetermined space being provided therebetween, and causes the second electrode to approach and recede from the first electrode in a movement direction by rotating; an operation body that is fixed movably relative to the fixed body in a state where the operation body is engaged with the movable body, and causes, by being operated by a user, the movable body to rotate; and a biasing part that is disposed between the movable body and the fixed body, and applies, to the movable body, a biasing force toward the support body.
