(First embodiment)
FIG. 1 is an overhead view of the HMD 10 according to the present embodiment. The HMD 10 includes a housing 110 that holds a display element (not shown) and a display optical system (not shown), a mounting part 210, an auxiliary part 310a, and an auxiliary part 310b (auxiliary member). FIG. 2 is a diagram for explaining that a user (user) (not shown), the auxiliary unit 310a, and the auxiliary unit 310b are held in contact with each other.

  First, the mounting part 210 (holding member) will be described. The mounting part 210 includes a joining part 401, a sponge 402, and a rubber band 403. A housing 110, a sponge 402, and a rubber band 403 are fixed to the joint portion 401. When the rubber band 403 expands and contracts and the sponge 402 comes into contact with the user's forehead, the housing 110 can be held on the user's head.

  Next, the auxiliary unit 310a will be described. The auxiliary portion 310 a includes a shaft 501, a stopper 502 (fixing member), a pad 503, and a sponge 504. The sponge 504 is fixed to the pad 503. The shaft 501 passes through the joint portion 401 and the pad 503. With these configurations, the sponge 504 can rotate about the shaft 501 as a rotation center, and can contact the user at a portion other than the mounting portion 210 and the contact surface of the user.

  Further, the pad 503 has a guide hole for the stopper 502, and the joint portion 401 has a groove 401a and a groove 401b for the stopper 502. The stopper 502 can be easily held in contact with the sponge 504 by being inserted into the groove 401a. Also, as shown in FIG. 3, by changing the groove into which the stopper 502 is inserted into the groove 401b, the sponge 504 can be easily held in a non-contact state with a user (not shown).

  If it is said structure, since the contact area will increase when the auxiliary | assistant part 310a contacts a user, the housing 110 can be more stably hold | maintained to a user's head rather than the contact of the mounting part 210 only. Moreover, the user who judges that the contact of the auxiliary part 310a is unnecessary can easily switch the auxiliary part 310a to the non-contact state with the HMD 10 attached.

  Next, the auxiliary unit 310b will be described. FIG. 4 shows a guide 110a that the housing 110 has and a boss 505a that the shield 505 has. With these shapes, the shield 505 can be shifted toward the user's face, and can contact the user at a portion other than the mounting portion 210 and the user's contact surface.

  Since the housing 110 has a groove in the direction of gravity, the shield 505 can be easily held in a contact state or a non-contact state by inserting a boss of the shield 505 into the groove.

  With the above configuration, the user can easily switch between securing or shielding the peripheral visual field while wearing the HMD 10. The mounting unit 210 may be anything as long as it can hold the casing 110 on the user's head, and the specific configuration is not limited. For example, as an alternative to generating a tightening force on the user's head by expansion and contraction of the rubber band 403, a belt whose length can be adjusted may be used. Moreover, you may generate | occur | produce a clamping force by pushing in the other mounting member with respect to one mounting member using a snap fit shape. Further, although the housing 110 is fixed via the joint portion 401, the rubber band 403 may be fixed to the housing portion 110. Further, the place of contact between the wearing unit 210 and the user is not limited to the head periphery, but may be the back of the head or the top of the head.

  Similarly, the auxiliary unit 310a and the auxiliary unit 310b may be in contact with the user at a portion other than the contact surface of the mounting unit 210 and the user, and may be held in a contact state or a non-contact state with the user. It is not limited. For example, the shaft 501 serving as the rotation center of the auxiliary portion 310a may not be located in the vicinity of the forehead. The stopper 502 may use a snap fit shape. Further, the contact portion between the auxiliary portion 310a and the auxiliary portion 310b and the user is not limited to the face portion and the top portion of the head, and may be a head circumference portion, a back head portion, a neck portion, or the like.

  Furthermore, the shield 505 does not necessarily have to be disposed on the side surface of the housing 110, and may be disposed on a surface corresponding to the vicinity of the user's eye of the housing 110. Further, the shield 505 may be divided, and the material of the portion that contacts the user may be an elastic body such as sponge or rubber.

(Second embodiment)
Next, the HMD 20 of the second embodiment will be described. In addition, about the structure which is common in 1st embodiment, the code | symbol same as 1st embodiment is attached | subjected and description is abbreviate | omitted.

  FIG. 5 is an overhead view of the HMD 20 of the second embodiment. The HMD 20 includes a housing 120 that holds a display element (not shown) and a display optical system (not shown), a mounting part 220, an auxiliary part 320c, and an auxiliary part 320d.

  6 will be described. The auxiliary portion 320 c includes a shaft 501, a stopper 502, a pad 503, a sponge 504, and a torsion spring 507.

  Even if the torsion spring 507 is deformed, the torsion spring 507 attempts to restore the initial shape by an elastic force. As shown in FIG. 6, the torsion spring 507 is fixed to the pad 503 and the joint 404, and the initial shape is designed so as to reduce the angle formed by the joint 404 and the pad 503. With this design, the spring urging force by the torsion spring 507 starts to act on the pad 503 by letting the stopper 502 escape from the groove 404a from the state of FIG. . As shown in FIG. 6B, since the pad 503 can be rotated about the shaft 501 as a rotation center, the sponge 504 can be rotated until it comes into contact with a user (not shown).

  If it is said structure, in addition to the effect of 1st embodiment, the non-contact holding mechanism can be cancelled | released. Then, since the spring-biased auxiliary portion 320c rotates until it comes into contact with the user, the auxiliary portion 320c can be disposed at an appropriate position without adjustment with respect to various user head shapes.

  Next, the auxiliary unit 320d will be described. As shown in FIG. 5, the auxiliary portion 320 d includes a shield 506 and a spring 508. FIG. 7 shows a guide 120 a included in the housing 120 and a boss 506 a included in the shield 506. With these shapes, the shield 506 can be shifted toward the user's face. As shown in FIG. 8, since the shield 506 is spring-biased by the spring 508, the shield 506 can be shifted until it comes into contact with the user at a portion other than the mounting portion 220 and the contact surface of the user. Further, as shown in FIG. 7, since the guide 120a of the housing 120 is branched in two directions, the shield 506 can be easily held in the non-contact state shown in FIG.

  If it is said structure, in addition to the effect of 1st embodiment, the non-contact holding mechanism can be cancelled | released. Then, since the spring-biased auxiliary portion 320d is shifted until it comes into contact with the user, the auxiliary portion 320d can be arranged at an appropriate position without adjustment with respect to various user head shapes.

  The auxiliary part 320c and the auxiliary part 320d may be in contact with the user at a part other than the contact surface of the mounting part 220 and the user, may be held in a non-contact state with the user, and may be spring-biased. Is not limited. For example, the spring that generates the spring biasing force may be a compression spring.

(Third embodiment)
Next, the HMD 30 of the third embodiment will be described. In addition, about the structure which is common in 1st embodiment, the code | symbol same as 1st embodiment is attached | subjected and description is abbreviate | omitted.

  FIG. 10 is an overhead view of the HMD 30 of the third embodiment. The HMD 30 includes a housing 130 that holds a display element (not shown) and a display optical system (not shown), a mounting part 230, an auxiliary part 330e, and an auxiliary part 330f.

  First, the mounting part 230 will be described. The mounting portion 230 shown in FIG. 13 includes a joint portion 405, a sponge 402, and a rubber band 403. There are three differences between the joint 405 and the joint 401. As shown in FIG. 11, the first is to have a screw hole for the dial 509 and a hole for the shaft 511. The second is that there is no stopper groove. The third is to have a shape that limits the movable range of the pad 512, and there is no other difference.

  Next, the auxiliary unit 330e shown in FIG. 11 will be described. The auxiliary portion 330e includes a shaft 511, a pad 512, a sponge 504, and a dial 509.

  The sponge 504 is fixed to the pad 512. The shaft 511 passes through the joint portion 405 and the 512a portion of the pad 512. With these configurations, the sponge 504 can be rotated about the shaft 511 and can contact the user at a portion other than the mounting portion 230 and the contact surface of the user. In addition, the dial 509 has a male screw shape and penetrates the 512b portion of the pad 512 and is fixed by the screw hole of the joint portion 405. Therefore, the sponge 504 can be easily held at an arbitrary position.

  If it is said structure, in addition to the effect of 1st embodiment, the auxiliary | assistant part 330e can be finely adjusted to the position which a user feels optimal.

  FIG. 12 shows a guide 130a and a screw hole 130b that the housing 130 has, and a boss 513a and a long hole 513b that the shield 513 has. With these shapes, the shield 513 can be shifted toward the user's face. Further, as shown in FIGS. 13 and 14, since the shield 513 is fixed by a dial 510 having a male screw shape, the shield 513 can be easily held at an arbitrary position.

  If it is said structure, in addition to the effect of 1st embodiment, the auxiliary | assistant part 330f can be finely adjusted to the position which a user feels optimal.

  The auxiliary unit 330e and the auxiliary unit 330f may be in contact with the user at parts other than the contact surface of the mounting unit 230 and the user and can hold the auxiliary unit 330e or the auxiliary unit 330f at an arbitrary position, and the specific configuration is not limited. .

  For example, a torque hinge may be used for holding the auxiliary portion 330e. That is, a torque hinge is arranged at the position of the shaft 511 shown in FIG. 11 and the torque hinge is fixed to the joint 405 and the pad 512. With this arrangement, the pad 512 can be held at an arbitrary position. Moreover, if the pad 512 can be held by the torque of the torque hinge, the male thread shape of the dial 509 is not necessary. Therefore, the dial 509 may be integrated with the pad 512.

  Similarly, the source of the holding force of the shield 513 may not be the screw of the dial 510. For example, if there is sufficient holding force to hold the shield 513, the shield 513 may be provided with a spring shape. Further, the holding force of the shield 513 may be given by another component such as a leaf spring.

  As mentioned above, although embodiment of this invention was described, various deformation | transformation and a change are possible for this invention within the range of the main point of this invention as a matter of course for the combination of these embodiment. In addition, from the viewpoint of ease of replacement, the auxiliary unit may be detachable from the housing or the mounting unit.
