Abstract

A display apparatus includes: an eyeglass-type frame worn by a head of a viewer; and an image display apparatus attached to the frame, wherein the image display apparatus includes an image formation device, and an optical device on which light that exits from the image formation device is incident, through which the light is guided, and out of which the light exits, the frame is formed of a front portion, two temple portions extending from both ends of the front portion, a nose pad, and an attachment member, the attachment member is attached to a central section of the front portion, the optical device is attached to the attachment member, and the nose pad is so attached to the attachment member that the nose pad is movable upward and downward.

First claim

What is claimed is:

1. A display apparatus comprising:
a frame;
a light guide;
an attachment member; and
a nose pad;
wherein
the attachment member includes a first member and a second member attached to the first member,
the first member includes a rectangular shaped hollow portion with an opening in a first side and a groove in a second side that is across from the first side,
at least a portion of the groove and a portion of the opening overlap one another along a plane that is parallel to a plane connecting centers of eyeballs of a viewer,
a first portion of an inner bottom surface of the rectangular shaped hollow portion that is closer to the opening than the groove includes at least one locking protrusion,
a latch member is attached to a second portion of the inner bottom surface of the rectangular shaped hollow portion that is closer to the groove than the opening,
a portion of the second member extends into the opening in the rectangular shaped hollow portion and includes locking recesses to engage with the at least one locking protrusion such that the second member is pivotally movable relative to the first member around an axial line parallel to a line connecting the centers of eyeballs of the viewer,
a top portion of the first member above the opening is attached to the frame,
the nose pad includes a portion that extends into the groove to attach to the latch member and is movable upward and downward with respect to the first member, and
the light guide is fixed to the second member and is moveable relative to the frame by moving the second member relative to the first member by engaging different ones of the locking recesses with the at least one locking protrusion.

2. The display apparatus of claim 1 , wherein the second member is pivotally movable relative to the first member such that the light guide is pivotally movable around an axial line parallel to the line connecting centers of eyeballs of the viewer.

3. The display apparatus of claim 1 , wherein the first member has a first side surface, a second side surface extending from one side end of the first side surface, a third side surface extending from the other side end of the first side surface, and a fourth side surface connecting the second side surface and the third side surface to each other.

4. The display apparatus of claim 3 , wherein the first side surface of the first member includes the top portion that is attached to a central section of the frame.

5. The display apparatus of claim 4 , wherein the groove is in the fourth side surface of the first member.

6. The display apparatus of claim 5 , wherein the second member includes a first side surface, a second side surface extending from one side end of the first side surface, and a third side surface extending from the other side end of the first side surface.

7. The display apparatus of claim 6 , wherein the light guide is attached to the first side surface of the second member, and wherein the first side surface is external to the rectangular shaped hollow portion.

8. The display apparatus of claim 7 , wherein the second side surface of the second member faces the second side surface of the first member, and the third side surface of the second member faces the third side surface of the first member.

9. The display apparatus of claim 8 ,
wherein through holes are formed through the second and third side surfaces of the first member and through holes are formed through the second and third side surfaces of the second member,
a first connecting member is inserted into the through hole formed through the second side surface of the first member and the through hole formed through the second side surface of the second member,
a second connecting member is inserted into the through hole formed through the third side surface of the first member and the through hole formed through the third side surface of the second member, and
the first and second connecting members are disposed along an axial line parallel to the line connecting the centers of the eyeballs of the viewer.

10. The display apparatus of claim 8 ,
wherein
the nose pad is formed of pad portions and a pad attachment portion, and
the pad attachment portion is movable upward and downward along the groove.

11. The display apparatus of claim 10 ,
wherein the latch member engages with the pad attachment portion.

12. The display apparatus of claim 1 ,
wherein the light guide is a half-silvered component.

13. The display apparatus of claim 1 ,
the latch member includes a plurality of connecting portions in the rectangular hollow portion behind the groove,
the nose pad includes a pad attachment portion with a latch receiver, and
the pad attachment portion is movable upward and downward along the groove by engaging the latch receiver portion with one of the plurality of connecting portions.

14. The display apparatus of claim 13 , wherein the plurality of connecting portions are recesses in the latch member and the latch receiver is a protrusion on the pad attachment portion.
