Input device
The conspicuity of a light emitting surface provided along an outer edge of an input member is enhanced. An input device ( 10 ) includes an upper cabinet section ( 41 ) having an opening formed therein, an input member ( 20 ) that has an upper surface to be touched by a user with a finger and that is disposed inside the opening, and a light diffusing member ( 71 ) having a light emitting surface (E 2 ) located along an outer edge of the input member ( 20 ). The light emitting surface (E 2 ) has a first region ( 71 g ) exposed in a gap between an inner edge of the opening of the upper cabinet section ( 41 ) and an outer edge of the input member ( 20 ) and a second region ( 71 h ) positioned on an inner side of the outer edge of the input member ( 20 ) and below a peripheral portion ( 21 a ) of the input member ( 20 ).
1. An input device comprising:
an exterior member having an opening formed therein;
an input member that has an upper surface to be touched by a user with a finger and that is disposed inside the opening; and
a light diffusing member having a light emitting surface located along an outer edge of the input member, wherein:
the light emitting surface has a first region exposed in a gap between an inner edge of the opening of the exterior member and an outer edge of the input member and a second region positioned on an inner side of the outer edge of the input member and below a peripheral portion of the input member,
the light emitting surface has an upper end located lower than the inner edge of the opening of the exterior member,
the light emitting surface is smoothly sloped in the first region and the second region to descend from the upper end toward below the peripheral portion of the input member,
a further gap is made between the outer edge of the input member and the light emitting surface,
the light emitting surface is visible through the further gap from diagonally above the input device.
2. The input device according to claim 1 , wherein the further gap is formed between the light emitting surface and the outer edge of the input member in an upward-downward direction.
3. The input device according to claim 1 , wherein the light emitting surface is inclined in the first region and the second region to extend downward toward the inner side of the outer edge of the input member.
4. The input device according to claim 3 , wherein the outer edge of the input member has a slope facing the light emitting surface.
5. The input device according to claim 1 , wherein
the outer edge of the input member has a first edge and a second edge that is an edge on a side opposite to the first edge, and
the light emitting surface includes a light emitting surface located along the first edge and a light emitting surface located along the second edge.
6. The input device according to claim 1 , wherein the light diffusing member surrounds the outer edge of the input member.
7. The input device according to claim 1 , wherein
the outer edge of the input member has a first edge and a second edge that is an edge on a side opposite to the first edge, and
the light diffusing member has a portion located along the first edge and a portion located along the second edge.
8. The input device according to claim 1 , wherein
the outer edge of the input member has a first edge and a third edge that is an edge crossing the first edge, and
the light diffusing member has a portion located along the first edge and a portion located along the third edge.
9. The input device according to claim 1 , further comprising: a light guide member positioned below the light emitting surface.
10. The input device according to claim 1 , wherein
the input member is movable in an upward-downward direction, and
the light diffusing member is fixed to the exterior member or a frame.
11. The input device according to claim 10 , wherein the light diffusing member has a stopper portion configured to restrict upward movement of the input member.
12. The input device according to claim 1 , wherein the light diffusing member has a front portion configured to restrict forward movement of the input member.
