Claim 0:
1. An input detection system comprising: a detection device including a plurality of detection electrodes arrayed in a detection region; an input support device including
a first input support electrode,
a second input support electrode provided so as to be movable on a concentric circle about a rotating axis overlapping with the first input support electrode, and
a coupling portion that electrically couples the first electrode and the second input support electrode;
a first detection electrode provided so as to face the first input support electrode;
a plurality of second detection electrodes provided at positions overlapping with the input support device and not facing the first input support electrode; and
a plurality of third detection electrodes provided at positions not overlapping with the input support device, wherein a position of the rotating axis of the input support device is fixed to the detection region of the detection device, and in detection of the second input support electrode:
a reference potential is supplied to one of the detection electrodes, the one corresponding to the first input support electrode; and
a drive signal is supplied to another one of the detection electrodes, the other one another one of the detection electrodes corresponding to the second input support electrode.
