Abstract:
To enable a user to visually recognize a position and a size of an operation input device on a touch panel display regardless of ambient lightness.SOLUTION: An operation input device 1 comprises: a holder 90 mounted to a touch panel display 100; a light guide member 50 through which light L from the touch panel display 100 is transmitted; a rotary disk body 30 rotatable in relative to the holder 90 and the light guide member 50; a pad 20 composed of a conductive material; and a pin 80 which is in contact with the pad 20 and detected as a detection point in the touch panel display 100, and composed of a conductive material. An outer diameter of the holder 90 is larger than an outer diameter of the rotary disk body 30, and a gap G in a vertical direction is formed between the holder 90 and the rotary disk body 30. The light guide member 50 changes light L from the touch panel display 100, in a direction in which the light moves outward from the gap G, and the rotary disk body 30 is rotated together with the pad 20 and the pin 80.SELECTED DRAWING: Figure 3
