Abstract

A display device according to an embodiment of the invention includes an image display unit for the left eye, an image display unit for the right eye, a main frame which supports the image display unit for the left eye and the image display unit for the right eye, and a position adjusting unit which adjusts positions of the image display unit for the left eye and the image display unit for the right eye with respect to the main frame. The position adjusting unit adjusts a gap between the image display unit for the left eye and the image display unit for the right eye, and respectively adjusts a position of the image display unit for the left eye with respect to the main frame, and a position of the image display unit for the right eye with respect to the main frame independently.

First claim

What is claimed is:

1. An image display apparatus comprising:
a first image display unit;
a second image display unit;
a support member which support the first image display unit and the second image display unit; and
a position adjusting unit which adjusts positions of the first image display unit and the second image display unit,
wherein the position adjusting unit adjusts a gap between the first image display unit and the second image display unit, and adjusts the position of the first image display unit with respect to the support member, and the position of the second image display unit with respect to the support member, respectively and independently.

2. The image display apparatus according to claim 1 ,
wherein the position adjusting unit includes
a connection member which adjusts a gap between the first image display unit and the second image display unit, and connects the first image display unit and the second image display unit;
a first elastic member which is arranged between the support member and the first image display unit, and is formed of an elastic material; and
a second elastic member which is arranged between the support member and the second image display unit, and is formed of an elastic material.

3. The image display apparatus according to claim 2 ,
wherein the connection member is configured of an elastic material.

4. The image display apparatus according to claim 2 , further comprising:
a deformation adjusting member which adjusts a deformation amount of the connection member.

5. The image display apparatus according to claim 2 ,
wherein an elastic modulus of the first elastic member is an elastic modulus which is different from that of the second elastic member.

6. The image display apparatus according to claim 2 , further comprising:
an elastic force adjusting unit which adjusts at least one of an elastic force of the first elastic member and an elastic force of the second elastic member.

7. The image display apparatus according to claim 1 ,
wherein the first image display unit and the second image display unit are see-through-type display units respectively each of which displays image light and natural light in an overlapping manner.

8. The image display apparatus according to claim 1 , further comprising:
a first index unit which has a first index denoting an image position in the first image display unit; and
a second index unit which has a second index denoting an image position in the second image display unit.

9. The image display apparatus according to claim 8 ,
wherein the first index unit is connected to the first image display unit in an overlapping manner through a first attaching-detaching unit, and
wherein the second index unit is connected to the second image display unit in an overlapping manner through the first attaching-detaching unit.

10. The image display apparatus according to claim 8 , further comprising:
an imaging unit which images the first index, the second index, and a pupil;
a detection unit which detects information on a deviation direction and a deviation amount in positions of the first index and the pupil, and information regarding a deviation direction and a deviation amount in positions of the second index and the pupil based on an imaging result of the imaging unit; and
an output unit which outputs the information which is detected using the detection unit.

11. The image display apparatus according to claim 8 , further comprising:
a reception unit which receives information on a deviation direction and a deviation amount in positions of the first index and a pupil, and information regarding a deviation direction and a deviation amount in positions of the second index and the pupil which are transmitted from an external device; and
an output unit which outputs the information received by the reception unit.

12. The image display apparatus according to claim 1 , wherein:
the first display unit is configured to be positioned in front of a first eye of a user; and
the second image display unit is configured to be positioned in front of a second eye of the user.
