Abstract

The input device has a fixed board and a movable board, which face with each other at established intervals. The fixed board has lower fixed-electrodes and upper fixed-electrodes, each of which has a band shape, in an orthogonal arrangement on the upper surface. The movable board has a movable electrode on all over the lower surface. Power is supplied to the lower-fixed electrodes and the upper fixed-electrodes only; the movable electrode is in no need of power supply, and therefore movable electrode 24 has no need for being connected to the fixed board and the controller. This eliminates a connector, providing a cost-reduced remote-control transmitter with a simple structure.

Claims

1. An input device comprising:

a fixed board comprising a plurality of band-shaped fixed electrodes in an orthogonal arrangement on an upper surface thereof, and

a movable board comprising a movable electrode on all over a lower surface thereof, the movable electrode facing the fixed electrodes at established intervals.

2. A remote-control transmitter comprising:

an input device of claim 1;

a controller connected to the fixed electrodes of the input device; and

a transmitter,

wherein, according to a state of electrical connections between the fixed electrodes, the controller requests the transmitter to transmit a remote-control signal.
