  By the way, in a head-mounted display or a spectacle-type display device, since a device for projecting an image is arranged at a portion where a lens is mounted in general spectacles, the weight of the front is larger than that of general spectacles. However, the burden on the user's nose is large. Therefore, even if the user moves his / her face a little, there are users who can easily shift the entire apparatus forward and feel pain in the nose due to the load on the front part.

  An object of the present invention is to provide a head-mounted display capable of appropriately preventing a shift in a state of being mounted on a user's head and obtaining a comfortable wearing feeling.

  The configuration of the present invention will be described below with reference to the embodiment, but the present invention is not limited to this embodiment.

  The head-mounted display (1) of the present invention includes an image display element (6R, 6L) for displaying an image, and light connecting the image display element (6R, 6L) and a user's visual axis (ER, EL). A magnifying optical system (7R, 7L) that is arranged on the road and projects the image displayed on the image display element (6R, 6L) to the user's eye, and the image display element (6R, 6L); A frame portion that positions the magnification optical system (7R, 7L) in front of the user's eyes, and the frame portion incorporates the image display element (6R, 6L) and the magnification optical system (7R, 7L). A front part (2) and a weight (5) whose one end is connected to the right end of the front part (2) and whose position in the direction connecting the one end and the other end can be adjusted. The right temple (3) where the A left temple portion (4) in which an end portion is connected to a left end portion of the front portion (2) and a weight (5) capable of adjusting a position in a direction connecting the one end portion and the other end portion is disposed. ).

  According to the head-mounted display of the present invention, the right temple part and the left temple part are provided with weights capable of adjusting the position in the direction connecting the one end part and the other end part. Weight balance can be obtained. That is, since the weight arranged in the temple portion acts as a counterweight with respect to the weight of the front portion, the load on the nose supporting the front portion is dispersed, and the entire device is prevented from slipping forward. A comfortable wearing feeling can be obtained.

  The head mounted display according to the first embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram schematically showing an appearance of a head-mounted display 1 according to the first embodiment. The head-mounted display 1 includes a front portion 2 containing an image display element and a magnifying optical system, one end connected to a right end of the front portion 2, and a weight 5 whose position can be adjusted at the other end. The right temple part 3 is arranged, and one end part is connected to the left end part of the front part 2, and the left temple part 4 is provided with a weight 5 whose position can be adjusted at the other end part. ing. The front portion 2, the right temple portion 3, the left temple portion 4, and the weight 5 constitute a frame portion of the head mounted display 1.

  The weight 5 is supported by a screw at the other end of the right temple portion 3 and the left temple portion 4 as shown in FIG. 1, and the screw has a predetermined length as shown in FIG. By rotating the screw, the position of the weight in the direction connecting the one end of the temple portion and the other end can be adjusted. Also, as shown in FIG. 1, the weight 5 can be exchanged by removing the weight 5 from the end of the temple portion by rotating the screw and attaching another weight 5 'having a different weight.

  On the front part 2 of the head-mounted display 1, as shown in FIG. 2, the image display elements 6R and 6L for displaying images and the images displayed on the image display elements 6R and 6L are enlarged to the user's eyes. Magnifying optical systems 7R and 7L for projecting and a drive unit 8 for driving the image display elements 6R and 6L to display an image. The magnifying optical system 7R is disposed on an optical path connecting the image display element 6R and the visual axis ER of the user's right eye, and enlarges and projects the image displayed on the image display element 6R onto the user's right eye. Similarly, the magnifying optical system 7L is disposed on the optical path connecting the image display element 6L and the visual axis EL of the user's left eye, and enlarges and projects the image displayed on the image display element 6L onto the user's left eye. To do. As the image display elements 6R and 6L, for example, a liquid crystal device such as a color liquid crystal display element is used.

  Further, the front unit 2 is provided with an operation knob (not shown) and the like, and when the user operates the operation knob, the positions of the image display elements 6R and 6L are set to, for example, the user's visual axes ER and EL. It can be moved in the direction along the line and adjusted to the optimum observation state.

  According to the head-mounted display according to the first embodiment, the weight balance between the front and rear of the head-mounted display is achieved by the weights respectively disposed at the other ends of the left and right temple portions. Therefore, when the user moves his / her face, it is possible to appropriately prevent the user from sliding forward. In addition, since the weight placed on the temple portion appropriately distributes the load on the nose that supports the front portion and reduces the burden on the nose, a comfortable wearing feeling can be obtained.

  Moreover, since the position of the weight can be adjusted and the weight can be exchanged, various users can be handled. That is, the degree of load reduction on the nose that supports the front portion can be changed according to the user's preference by adjusting the position of the weight or exchanging the weight. Can be realized.

  FIG. 3 is a diagram schematically showing the appearance of a head-mounted display according to the second embodiment of the present invention. The head mounted display 10 includes a front part 2, a right temple part 11, a left temple part 12 and a weight 13. Since the front part has the same configuration as the front part of the head-mounted display 1 according to the first embodiment, the same reference numerals are used and detailed description thereof is omitted.

  The right temple portion 11 and the left temple portion 12 support a weight 13 and a weight 13 at a position from a substantially central position from the front portion 2 (one end portion) to the other end portion to the other end portion. A slidable groove 14 is formed. That is, by sliding the weight 13 along the groove 14, the position of the weight 13 in the direction connecting the one end of the temple portion and the other end can be adjusted. In the head-mounted display according to the second embodiment, the weight 13 is replaced with another weight having a different weight as in the head-mounted display according to the first embodiment. be able to.

  According to the head mounted display according to the second embodiment, since the weight is supported and slidable by the grooves formed in the left and right temple portions, the position of the weight can be easily adjusted. it can. Therefore, it is possible to easily adjust the position of the weight in the range where the groove is formed, appropriately reduce the load on the nose supporting the front portion, and easily obtain a comfortable wearing feeling.

  The weights used in the head mounted display according to the above-described embodiment are not limited to those shown in FIGS. That is, as long as a predetermined weight can be obtained, the weight may have any shape or material.

  Further, in the head-mounted display according to the above-described embodiment, one weight is disposed in each of the left and right temple portions, but a plurality of weights may be disposed. For example, when the weights can be connected to each other, the weight of the weight may be adjusted by connecting another weight to the already arranged weight.

It is a figure which shows typically the external appearance of the head mounted display which concerns on the 1st Embodiment of this invention. It is a figure which shows the internal structure of the head mounted display which concerns on the 1st Embodiment of this invention. It is a figure which shows typically the external appearance of the head mounted display which concerns on the 2nd Embodiment of this invention.
