Abstract
An input device includes a manipulation surface, a light emitting circuit disposed along the manipulation surface, and a detection circuit configured to detect an action of a finger on the manipulation surface. The light emitting circuit has first and second segment groups. The second segment group is disposed along the first segment group. The first segment group emits light at a first intensity if the detection circuit is restricted to receive a prescribed input. The first segment group emits light at a second intensity if the detection circuit is allowed to receive the prescribed input. A part of the second segment group emits light if the detection circuit detects an action of the finger alongside the first segment group while the first segment group is emitting light at the second intensity.
