As described above, the head-mounted display device is used for a portable information processing device. Therefore, it has been demanded to improve the portability and storability thereof. Was not taken into account.

In recent years, very small display units having a screen diagonal dimension of, for example, 0.5 inch or less have been developed. Therefore, a reduction in the size and weight of the holder has been demanded in addition to the display unit. However, conventional compact and lightweight holders are supported by only two points on the left and right heads, such as the above-mentioned headphone type, those that are simply wound around from the temporal region to the back of the head, such as the band type, and those that are eyeglass type. And could not be attached to the head sufficiently stably.

In a head-mounted display device, it is necessary to arrange at least a part of the display unit in front of the wearer's eyes, so that the weight acts unbalanced on the wearer's head. Then, a large moment acts on the head due to the acceleration acting on the display unit by moving the head, and the holder moves with respect to the head, and the displayed image is shifted from the field of view of the wearer and visibility is reduced. .

To stably mount the head-mounted display device, it is conceivable to increase the support area of the holder by the head or increase the number of support points. However, this increases the size and weight of the holder.

Further, when the display unit is mounted on a spectacle type holder, a large load acts on the face such as the upper part of the nose for a wearer who does not normally use spectacles. There is a problem.

An object of the present invention is to provide a holder for a head mounted display device which can solve the above problems.
