An observer can observe a video in a state in which the visual line of the observer is caused to overlook the downward side. In particular, in a virtual image display apparatus, even when the positions of the eyes, the nose, and the ears of the observer deviate from standard positions and the observer cannot observe a video in a targeted overlooking direction in a worn state in standard setting, it is possible to change an angle in an overlooking direction with respect to a front direction and cause the observer to perform observation in a suitable visual line by changing, with a nose receiving section functioning as an adjusting section, the posture of the virtual image display apparatus and adjusting an emission state of video light from a light guide member according to individual differences of the observer. |

1. A virtual image display apparatus comprising:
a video device; a light guide member arranged in front of an eye of an observer and configured to direct light emitted from the video device to the eye of the observer and cause the observer to visually recognize an image; a frame configured to arrange the light guide member in a predetermined position in front of the eye and support the light guide member on the basis of a support position reference plane decided assuming at least a standard position of the eye; and an adjusting section configured to adjust an emission state of the light from the light guide member with respect to the eye of the observer, the adjusting section including a nose receiving section configured to come into contact with a nose of the observer and to support the virtual image display apparatus during wearing, the adjusting section changing a posture of the nose receiving section, wherein the adjusting section further includes a plurality of pad sections that are brought into contact with the nose, the pad sections being attached to a part of the nose receiving section, wherein the adjusting section further includes a plurality of convex sections disposed in a row on an apparatus main body section of the adjusting section, wherein the plurality of pad sections include a pair of separate left and right pad sections each comprising a plurality of concave sections spaced side by side in a row so as to correspond to and be interactable with the plurality of convex sections on the apparatus main body section of the adjusting section, wherein the nose receiving section is positioned and fixed by fitting the concave sections of the pad sections with the convex sections on the apparatus main body, and a height of the nose receiving section is adjusted by changing positions in which the concave sections of the left and right pad sections are combined with the convex sections, wherein the light guide member emits light, which the light guide member should cause the observer to visually recognize, from a direction angled with respect to the support position reference plane and causes the observer to visually recognize the image from an overlooking direction for causing the eye of the observer to overlook a downward side, and wherein the adjusting section changes an angle in the overlooking direction with respect to the position of the eye of the observer by adjusting an emission state of the light from the light guide member. |
