Abstract

PURPOSE: To attain the protection of optical parts at the time of carrying and the reduction of the intrusion of external light at the time of mounting in spectacles type head mounted display. CONSTITUTION: This spectacles type head mounted display is constituted of a pair of handles 2R and 2L provided with a foldable root part whose width is wide and the handles 3R and 3L which are ear hanging top end parts respectively attached so that the position of a rotary shaft may be movable to the handles.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head mounted display (hereinafter referred to as "HMD") which can be worn on the head to view video information.

[0002]

2. Description of the Related Art In recent years, with the development of image display devices such as liquid crystal panels, various types of image display devices have been developed. One of them is a head mounted display (HMD), and various types have been commercialized.
For example, for glasses type HMD, Japanese Patent Application No. 3-2
No. 39120. This glasses-type HMD is provided with a backlight and a visual device including a liquid crystal panel illuminated by the backlight in the main body of the device, and is made of a liquid crystal panel by the illumination of the backlight of the visual device. The video image is enlarged by a pair of eyepieces and projected on the retina of the eyeball.
A pair of handles is foldably attached to both sides of the back of the device body, and the device body is attached to the face through the pair of handles so that the enlarged video image can be viewed. . Further, the front surface of the apparatus body is composed of a half mirror or the like, so that the appearance of the outside can be seen while the apparatus body is still attached to the face.

[0003]

However, most of the above-mentioned conventional eyeglass-type HMDs are lightweight, compact and highly portable, but have not been specially considered as portable. However, there is a problem in that it is vulnerable to scratches and dust on the optical parts when being carried, and intrusion of external light when being mounted.

The present invention has been made to solve the above problems, and is effective for scratching and dusting optical parts when carried, and for shielding external light for improving visibility when mounted. The purpose is to provide such a configuration.

[0005]

In order to solve the above-mentioned problems, the HMD of the present invention has a pair of foldable and wide base portions, and the rotation shaft can be moved to each of the pedestals. It consists of a handle on the tip part for attaching to the ear.

[0006]

With the above structure, it becomes possible to protect the optical components from scratches and dust when they are carried and to reduce the invasion of external light when they are mounted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of an HMD according to an embodiment of the present invention will be described below with reference to the drawings. 1 is a perspective view of an HMD according to an embodiment of the present invention, and FIG. 2 is a front view thereof.

In FIG. 1 and FIG. 2, the HMD main body 1 is composed of two image display modules composed of optical parts such as a liquid crystal panel and a lens, and a video circuit board for driving the liquid crystal panel. . In FIG. 1, H
The pair of handles foldably attached to the MD main body 1 is composed of a handle 2L, 2R having a wide root portion and a handle 3L, 3R having a tip portion for ear hooking. The width of the root portion is set to a size sufficient to cover the video display module. The handles 3L and 3R at the tip of the ear hook are foldably attached to the insides of the handles 2L and 2R at the wide base. Also, the position of the rotating shaft for folding is adjustable inside the handles 2L, 2R of the wide base part, so that the ear hook position can be adjusted for many people. When worn, the pair of wide stalks 2L and 2R at the base portion are positioned so as to sandwich both sides of the eyeball, which is effective in reducing the invasion of external light from both side surfaces and the upper surface of the head. further,
At the time of storage, the handles 3L, 3R at the tip for ear hooks are folded inside the handles 2L, 2R at the wide base part, and the handles 2L, 2R at the wide base part are the optical parts of the HMD body 1. Since it is folded so as to cover it, it covers and protects the optical components.

With the above structure, it is possible to prevent scratches and dust on the optical components due to careless handling during carrying and to reduce intrusion of external light during mounting.

[0010]

As described above, according to the HMD of the present invention,
In a highly portable glasses-type HMD, scratches and dust on optical parts due to careless handling can be prevented, and external light entering from both side surfaces and the top surface of the head can be reduced during wearing. Therefore, it is possible to enhance the immersive feeling in the video software.
