Abstract

A head mounted display includes a first optical housing mounting a light source and an optical component, a second optical housing mounting an image generating element and an optical component, a securing member connecting and securing the first optical housing and the second optical housing, and an exterior housing holding the first optical housing, the second optical housing, and the securing member. The securing member is fitted with the first optical housing with the second optical housing enclosed to connect and secure the first optical housing and the second optical housing.

Claims

1. A head mounted display emitting a beam from a light source to an image generating element and displaying a generated image in a direction of a user'"'"'s field of view, the head mounted display comprising:

a first optical housing mounting the light source and an optical component;

a second optical housing mounting the image generating element and an optical component;

a securing member connecting and securing the first optical housing and the second optical housing; and

an exterior housing holding the first optical housing, the second optical housing, and the securing member,

wherein the securing member is fitted with the first optical housing with the second optical housing enclosed to connect and secure the first optical housing and the second optical housing.

2. The head mounted display according to claim 1, wherein a securing direction by means of the securing member is a direction of an optical axis when a beam from the light source is emitted from the first optical housing and enters the second optical housing mounting the image generating element.

3. The head mounted display according to claim 2, wherein the first optical housing and the second optical housing are arranged to be piled in a perpendicular direction when the user equipped with the head mounted display stands up straight.

4. The head mounted display according to claim 2, wherein a fitting state between the securing member and the first optical housing is a state in which a fitting hole provided in the securing member hangs on and is secured to a projection provided in the first optical housing.

5. The head mounted display according to claim 4, wherein the securing member and the first optical housing are secured in the direction of the optical axis by a securing screw.

6. The head mounted display according to claim 1, wherein heat dissipating materials are respectively arranged between the securing member and the light source mounted on the first optical housing, and between the securing member and the image generating element mounted on the second optical housing.

7. The head mounted display according to claim 6, wherein a heat dissipating material is arranged between the securing member and the exterior housing.
