HEAD-MOUNTED DISPLAY DEVICE
First Claim
1. A head-mounted display device, comprising:
- a first casing which incorporates therein at least a display element, and has a light projection window for projecting image light from the display element;
a second casing which incorporates therein an eyepiece optical system with a refractive power, and has a light receiving window for receiving the incident image light projected through the light projection window and an eyepiece window for emitting the image light that has passed through the eyepiece optical system; and
a coupling portion for coupling the second casing to the first casing so as to make adjustable a length of an optical path between the light projection window and the light receiving window.

Abstract
Provided is a head-mounted display element, including: a first casing (11) which incorporates therein at least a display element (21), and has a light projection window (11a) for projecting image light from the display element (21); a second casing (12) which incorporates therein an eyepiece optical system (31) with a refractive power, and has a light receiving window (12a) for receiving incident image light projected through the light projection window (11a) and an eyepiece window (12b) for emitting the image light that has passed through the eyepiece optical system (31); and a coupling portion (13) for coupling the second casing (12) to the first casing (11) so as to make adjustable a length of an optical path between the light projection window (11a) and the light receiving window (12a).

15. A head-mounted display device, comprising:
-
a display element; a casing accommodating the display element; an eyepiece optical system with a positive refractive power, which receives image light incident from the display element, guides the image light to the front of an eyeball of the wearer, and emits the image light toward the eyeball, so as to make observable a virtual image formed by the image light; and a slide operation portion which is provided so as to be slidable, with respect to the casing, in the anteroposterior direction of the head of the wearer, wherein the slide operation portion is coupled to at least either the display element or an optical element in the eyepiece optical system in such a manner that a length of an optical path between the display element and the optical element is increased when the slide operation portion is slid in the anterior direction of the wearer. - View Dependent Claims (16, 17, 18, 19, 20)
