Abstract:
A light guide system includes a transparent light guide portion that guides light beams incident from one end side to a light-emitting portion. The light guide portion includes a plurality of partial reflection surfaces that are disposed between a first surface and a second surface which are parallel to each other and are inclined at the same angle such that a first end portion is positioned closer to the one end side than a second end portion is. Intervals between the partial reflection surfaces in a first direction are widened from the one end side toward another end side. In a state where the light guide portion is disposed in front of an eye of an observer, the light guide portion is inclined such that the another end side is further away from a face of the observer than the one end side is.

Claim (Index 11):
A light guide device comprising:\n a transparent light guide portion that guides light beams incident from one end side to a light-emitting portion, wherein the light guide portion includes a first surface extending from one end side on which the light beams are incident toward the another end side in a first direction, a second surface extending in the first direction so as to be parallel to the first surface on one side of a second direction intersecting with the first direction, and a plurality of partial reflection surfaces which are disposed along the first direction between the first surface and the second surface and are inclined at the same angle from a normal direction with respect to the second surface toward the one end side, wherein intervals between the plurality of partial reflection surfaces in the first direction are widened from the one end side toward the another end side, and wherein, in the two partial reflection surfaces adjacent to each other in the first direction among the plurality of partial reflection surfaces, an angle formed by an imaginary straight line and the second surface is equal to or larger than 90\u00b0, the imaginary straight line being a line connecting an end portion of the partial reflection surface, which is positioned on the one end side in the first direction, on one side of the second direction and an end portion of the partial reflection surface, which is positioned on the another end side in the first direction, on the another side of the second direction.
