Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spectacle-type image display device capable of viewing an image on the head like glasses.

[0002]

2. Description of the Related Art Japanese Laid-Open Patent Publication No. 1-1334 discloses a display device capable of viewing an image on the head like glasses.
In No. 79, the light emitting part of the TV is arranged so as to be the blind spot of both eyes, and a long trapezoidal reflector is arranged below it at the position where the blind spots of both eyes are arranged, and the emitted television image is reflected by the mirror. There is disclosed a visual device which is reflected by a mirror and is reflected by a concave mirror, and is arranged so that the concave mirror just focuses the light on both eyes, and these are detachably attached to the head like ski goggles.

[0003]

Although the above-mentioned visual device is a headphone type television that can be worn on the head,
The emitted television image is located between the eyes just in front of the nose, which is the blind spot of both eyes, and the television image is reflected by a concave mirror to see a large image with both eyes. The distance is only about 3 cm, and it is impossible for the reflector of this width to make it visible to both eyes even if the image is magnified by the concave mirror. In view of this, the present invention provides an eyeglass-type image display device in which an optical system for image display is improved so that an image is placed at an appropriate position in front of the eye for easy viewing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 is a diagram showing the state of use of the eyeglass-type image display device of the present invention. When the eyeglass-type image display device 10 is used, it is put on the face portion 1 of the human body like eyeglasses. Then, the TV tuner 20 and the battery box 30 are attached to the waist belt 2, and the connection cords 21 and 3 are respectively attached.
At 1, the eyeglass-type image display device 10 is connected. As a result, the image from the television tuner 20 can be observed on the eyeglass-type image display device 10.

FIG. 2 is a perspective view of the eyeglass-type image display device. FIG. 3 is a plan view of an optical system of the eyeglass-type image display device.

The spectacle-type image display device 10 includes a rectangular main body 11 having a gentle curved surface along the front surface of the head, and the main body 1.
Ear hooks 12 and 12 are attached to both sides of 1. The binocular position corresponding to the face side on the back surface of the main body is open, and eyepieces 13 and 13 are provided in the openings. At the front side position in the main body part in front of both eyes,
Square mirrors 14 and 14 are provided, respectively, and the reflecting surfaces of the mirrors are vertically provided so that the line of sight when looking at the front is reflected by the square mirrors 14 and 14 toward the central face side in the main body. On the face side of the main body 11, the cross section is V-shaped in the left and right along the nose, the mirror surface is the outer surface of the V-shape, and the degree of opening of the V-shape is the line of sight reflected by the rectangular mirrors 14, 14. V-shaped mirror 15 that is angled to reflect to the center of the surface of the main body
Is installed vertically. The main body 11 has an LCD at the center on the front side.
A small image display unit 16 made of (Liquid Crystal Display) is attached vertically with the display surface facing the nose.

An observer wearing the spectacle-type image display device 10 having the above-described optical system can see the line of sight of the eyepiece lens 13,
Each of the mirrors 14 and 14 in front of the eye is seen through the mirror 13. The mirrors 14 and 14 reflect the line of sight to the V-shaped mirror 15, and the V-shaped mirror 15 reflects the line of sight to the surface of the main body. The image on the image display unit 16 is viewed with both eyes by reflecting it to the center.

In FIG. 1, a drive circuit board 17 for driving the image display unit 16 is arranged on the upper surface of the main body 11, and tuner jacks 2 are provided on the left and right of the front of the main body.
2. A battery jack 32 is provided and connected to the drive circuit board 17.

As shown in the plan view of the optical system of FIG. 4, an objective lens 18 may be provided in front of the display surface of the image display section. Further, although not shown, an earphone may be provided so that the sound can be heard. If the mirrors 14 and 14 are half mirrors so that the surface of the main body 11 can be seen through, while watching the image displayed on the image display unit 16,
You can also see the outside scenery, so you can see the image while walking. The eyepiece lens 12 and the objective lens 18 may be Fresnel lenses. When using the glasses-type image display device 10, it is possible to enjoy the game image by using the TV tuner 20 as a main body of a portable video game machine. Further, it is possible to incorporate a video game machine in the glasses-type image display device itself.

[0012]

As described above, the eyeglass-type image display device of the present invention can be worn by the observer wearing the main body like eyeglasses. Since the image display is projected in front of the eyes and the image displayed on the image display unit is reflected twice, the image entering the observer's eye is not an inverted image but an upright image. Furthermore, since the eyes can be viewed with both eyes without difficulty, the eyes are less tired. Therefore, the optical system for displaying the image is improved, and the image is placed in an appropriate position in front of the eye for easy viewing.
