Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a head which is detachably attached to an observer's head and used to directly project an observed image on the retina in the eyeball of the observer in an enlarged manner. The present invention relates to a wearable display device, and more particularly to an improvement in a means for detachably mounting and holding a video display main body on the head of an observer.

[0002]

2. Description of the Related Art In recent years, an image obtained from a small CRT or an image display device such as a liquid crystal display device is directly projected onto the retina in the eyeball of an observer by a projection optical system, so that the image appears in the air. Head-mounted display devices, such as goggles or helmets, have been developed that enable observation of virtual images as if they were magnified and projected. In this type of head-mounted image display device, in order to allow an observer to easily experience a highly realistic image observation,
It is necessary to sufficiently magnify the screen of a relatively small image display element to give the effect of looking at a large screen, and in particular, the image display body to the observer's head. It is relatively easy to mount and hold and handle, and it also makes the feeling of wearing good in terms of weight balance and stability at the time of wearing, and further, the entire device is configured as small and lightweight as possible. Therefore, it is required to make it convenient to carry.

Therefore, when using the head-mounted display device, it is natural that the size and shape of the head of the observer differ from person to person due to various individual differences.
Since the feeling of use of the display device, in particular, the feeling of wearing the display device also varies from person to person, it is necessary to suppress fatigue and discomfort of the observer when wearing and using the display device as much as possible. It is necessary to devise various means for mounting and holding means for the head in the above, and in order to meet the demand, in the conventional case, for example, Japanese Patent Laid-Open No. 3-188777, Japanese Utility Model Laid-Open No. 63-94420, JP-A-5-8
Each mounting adjustment mechanism disclosed in Japanese Patent No. 8107 and the like has been proposed.

On the other hand, in a head-mounted display device of this type, it goes without saying that the head-mounted display device is mounted in such a manner that it is supported on the head side of the observer's face. Therefore, body fluids such as sweat secreted from the face and the head, cosmetics, hair styling products, and the like are inevitably attached to the wearing portion, which not only causes discomfort during use, It is also unsanitary, and in particular, when an unspecified number of observers use the same device, as a result, body fluids, cosmetics, hair dressing, etc. of other people may be attached each time they are used. However, the discomfort is more severe and it is extremely unsanitary.

[0005]

The adjusting mechanism for each mounting in the conventional head-mounted display device described above has the following problems, respectively.

First, in the case of the respective device configurations proposed by the above-mentioned Japanese Patent Laid-Open Nos. 3-188777 and 63-94420, both of the display devices are adjusted according to the size of the observer's head. The holding means is provided so that the length of the mounting support band can be changed. That is, in the former Japanese Patent Laid-Open No. 3-188777, a method is used in which the ends of the mounting support band can be engaged and disengaged with a velcro, but it is not necessarily satisfactory in terms of usability. However, the weight balance at the time of wearing, the lack of stability, and the feeling of wearing and the feeling of use are not preferable either. Especially, once the hair is worn, the hair is worn and loosened, so that the hair is worn one by one. There is an inconvenience that it must be reattached, and moreover, it is impossible to deal with stains on the image display main body and the support band. Also, in the latter Japanese Utility Model Laid-Open No. 63-94420, a method is adopted in which the end portions of the mounting support band are inserted into each other so that they can be engaged and disengaged, and a sponge for cushioning is provided inside the support band. Although the pad is intervening and devised so as to fit the shape of the head relatively easily, in other respects, it has almost the same drawbacks as the former case.

On the other hand, in the case of the device structure proposed by the above-mentioned Japanese Patent Laid-Open No. 5-88107, the image display main body is directly attached to the eaves portion of a general sun visor which is used by being fitted on the head. , Adopting a detachable installation method. Therefore, a plurality of sun visors as mounting and holding means here, in particular, a plurality of sun visors having different reference dimensions are prepared respectively, and the sun visor can be arbitrarily set. It can be said that both of them are effective in selecting and using them, in that they are well attached and held on the head of the video display main body, and that they ensure hygiene.
Along with the fact that the sun visor itself is relatively simple, including the disadvantage of preparing a plurality of sun visors, there is a drawback that it lacks weight balance and stability during use.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and its purpose is to provide an adjusting mechanism means for mounting the image display main body on the observer's head. Head-mounted display device, in particular, its mounting means, which can be more simply and comfortably and stably supported and can also ensure hygiene if necessary. Is to provide.
