The display unit 10, which is the main part of the head-mounted display 100, has an eyeglass shape, and includes a pair of left and right light guide plates 11R and 11L and a pair of left and right display units 12R and 12L.

The pair of light guide plates 11R and 11L is an optical section made of a light-transmitting resin or the like, and is made of, for example, a prism. The right light guide plate 11R is positioned in front of the right eye of the user when the head mounted display 100 is worn on the head, and the left light guide plate 11L is used when the head mounted display 100 is worn on the head. located in front of the person's left eye.

The right light guide plate 11R allows the right eye to view the image realized by the right display unit 12R, and the left light guide plate 11L allows the left eye to view the image realized by the left display unit 12L. The image light guided to the pair of light guide plates 11R and 11L is incident on the right and left eyes of the user to allow the user to visually recognize a virtual image, thereby displaying the image on the display unit 10. FIG.

Either one of the display units 12R and 12L (the display unit 12L in the illustrated example) has one end of a cable 14 connected to a controller (not shown) that controls the functions of the display unit 10 and turns the power ON/OFF. is connected. The user realizes various functions of the head mounted display 100 by holding the controller in his hand and operating it with his fingers.

The display unit 10 also includes a camera 13 . The camera 13 is a digital camera equipped with an imaging device such as a CCD or CMOS, an imaging lens, and the like, and captures an image of the direction in which the user gazes. The camera 13 is arranged on the front surface of the display unit 10 at a position that does not block external light passing through the light guide plates 11R and 11L.

The display unit 10 also incorporates a plurality of sensors (not shown) such as a gyro sensor, a knock sensor, and an acceleration sensor.

A frame 1 for holding the display unit 10 mounted on the user's head is detachably mounted on the head mounted display 100 of the present embodiment.

As shown in FIG. 3, the frame 1 includes a frame main body 1A having a substantially U-shaped outer shape, a mounting portion 1B provided in the front central portion of the frame main body 1A and connected to the frame main body 1A, and a frame main body 1A. It is composed of a pair of pads 1R and 1L provided on both left and right sides.

The frame main body 1A is a portion that abuts on the side of the user's head when worn (see FIG. 5), and is elastically deformable in order to facilitate attachment and detachment from the user's head. It is made of a flexible material such as a synthetic resin that is easy to handle. The mounting portion 1B may be integrally molded with the same material as the frame main body 1A, or may be configured with a flexible material different from that of the frame main body 1A.

In order to attach the illustrated frame 1 to the display section 10 of the head mounted display 100, the attachment section 1B is gripped with fingers, and the lower end of the attachment section 1B is inserted into the long groove 15 (see FIG. 4) in the center of the front surface of the display section 10. just fit it in. Further, when the mounting portion 1B fitted in the long groove 15 is grasped and pulled with fingers, the lower end portion of the mounting portion 1B is elastically deformed and easily removed from the long groove 15, so that the frame 1 can be easily removed from the display portion 10. can be done. The mounting position and shape of the mounting portion 1B connected to the frame main body 1A, the mounting position and shape of the long groove 15 provided in the display portion 10, and the method of attaching and detaching the frame 1 to and from the display portion 10 are limited to the illustrated example. Instead, various design changes are possible.

Each of the pair of pads 1R and 1L provided on the frame 1 protrudes from the lower surface of the frame body 1A and abuts against the user's cheek when worn (see FIG. 5). That is, the frame 1 is mounted on the user's head by the frame main body 1A contacting the user's temporal region and the pair of pads 1R and 1L contacting the user's cheek. is configured to securely hold the

In the illustrated example, each of the pair of pads 1R and 1L protrudes forward. In this way, the present inventors found that when the pads 1R and 1L protrude forward, the ability to hold the display unit 10 is improved compared to when the pads 1R and 1L protrude rearward. It has been clarified by the examination of and the questionnaire survey from the try-on person.

According to the head-mounted display 100 having the frame 1 of the present embodiment configured as described above, it is possible to hold the display section more securely than the conventional technique in which the display section is held by the frame alone.

In addition, since there is no weight burden on the nose unlike the conventional technology in which the display is held by a frame and a nose pad, the head-mounted display 100 can be comfortably worn for a long time.

Furthermore, since the frame 1 is detachably attached to the display unit 10, each user has his or her own frame 1, so that when the head-mounted display 100 is worn, other users' It is possible to eliminate the discomfort of touching the frame or nose pad that touches the skin.

Although the invention made by the present inventor has been specifically described based on the embodiment, the invention is not limited to the above embodiment, and can be variously modified without departing from the gist of the invention. Needless to say.

For example, a structure in which the display section 10 is rotatably supported with respect to the mounting section 1B of the frame 1 may be employed.

In this case, as shown in FIG. 6, the user manually flips up the display unit 10 to enable forward visual recognition with the naked eye while wearing the head mounted display 100 on the head, and By manually returning the flipped-up display unit 10 to its original position, the image displayed on the display unit 10 can be immediately viewed, which is convenient.
