Instead, a plurality of prism grooves 11 can be formed in a stripe shape on the lower surface of the planar light guide plate 5, that is, on the wiring board 1 side.
- the actuator 7 and the cover sheet 8 formed separately are joined afterwards, but the gist of the present invention is not limited to this.
- the light-emitting diode 2 is provided on the linear light guide plate 4.
- the gist of the present invention is not limited to this, and the light-emitting diode is provided on the wiring board 1.
- a configuration may be adopted in which the light guide plate 2 is mounted and directly incident on the planar light guide plate 5.
- FIG. 1 is an exploded perspective view of an input device with an illumination function according to an embodiment.
- FIG. 2 is an exploded side view of the input device with an illumination function according to the embodiment.
- FIG. 3 is a cross-sectional view of the assembled input device with an illumination function according to the embodiment.
- FIG. 4 is a plan view of the main part showing the configuration of the linear light guide plate according to the embodiment and the arrangement of the linear light guide plate with respect to the planar light guide plate.
- FIG. 5 is a plan view of a planar light guide plate according to an embodiment.
- FIG. 7 is a cross-sectional view of a principal part showing an assembled state of the wiring board, the light guide plate, and the metal dome according to the embodiment.
