Display apparatus
First Claim
1. A display apparatus comprising:
- a glass-type frame that is mounted to a head of an observer; and
two image displaying devices for the left and right eyes that are attached to the frame,wherein each of the image displaying devices includesan image forming device,an optical system that makes light output from the image forming device to be parallel light, andan optical device to which the light output from the optical system is incident, and in which the light is guided so as to be output,at least one of the image displaying devices further includes a movement device that relatively moves an optical axis of the image forming device and an optical axis of the optical system in a horizontal direction, anda convergence angle is adjusted by relatively moving the optical axis of the image forming device and the optical axis of the optical system in the horizontal direction by using the movement device depending on an observation position of an observer.

Abstract
A display apparatus includes: a glass-type frame mounted to a head of an observer; and two image displaying devices for the left and right eyes that are attached to the frame. Each of the image displaying devices includes an image forming device, an optical system making light from the image forming device to be parallel light, and an optical device to which the light from the optical system is incident, and in which the light is guided so as to be output, at least one of the image displaying devices further includes a movement device relatively moving optical axes of the image forming device and the optical system in a horizontal direction, and a convergence angle is adjusted by relatively moving the optical axes of the image forming device and the optical system in the horizontal direction using the movement device depending on an observation position of an observer.

2. A display apparatus comprising:
-
a glass-type frame that is mounted to a head of an observer; and two image displaying devices for the left and right eyes that are attached to the frame, wherein each of the image displaying devices includes an image forming device, an optical system that makes light output from the image forming device to be parallel light, and an optical device to which the light output from the optical system is incident, and in which the light is guided so as to be output, at least one of the image displaying devices further includes a rotary movement device that rotates the image forming device and the optical system, and a convergence angle is adjusted by rotating the image forming device and the optical system by using the rotary movement device depending on an observation position of an observer so as to change an incidence angle of the parallel light that is output from the optical system and is incident to the optical device with respect to the optical device.
