Abstract

A head-mounted display apparatus includes a display unit configured to emit image light to display an image, a support portion that supports the display unit, and a nose pad attached to the support portion. The support portion includes an attachment portion to which the nose pad is attached. The nose pad includes an insertion portion inserted into the attachment portion. The attachment portion includes an insertion opening into which the insertion portion is inserted, and a locking portion configured to lock the nose pad in a first position and a second position that are different from each other in a rotational direction of the nose pad centered at the insertion portion inserted into the insertion opening.

Claims

1. A head-mounted display apparatus, comprising:

a display unit configured to emit image light to display an image;

a support portion that supports the display unit; and

a nose pad attached to the support portion, wherein the support portion includes an attachment portion to which the nose pad is attached,

the nose pad includes an insertion portion inserted into the attachment portion, and

the attachment portion includes an insertion opening into which the insertion portion is inserted, and

a locking portion configured to lock the nose pad in a first position and a second position that are different from each other in a rotational range of the nose pad centered at the insertion portion inserted into the insertion opening.

2. The head-mounted display apparatus according to claim 1, wherein

the nose pad includes a first nose rest portion and a second nose rest portion,

a rotational direction of the nose pad is a direction intersecting a first axis that connects the first nose rest portion and the second nose rest portion when viewed from a first direction in which the display unit emits the image light, and

the attachment portion includes, as the locking portion,

a first locking portion configured to lock the nose pad in the first position, and

a second locking portion configured to lock the nose pad in the second position.

3. The head-mounted display apparatus according to claim 2, wherein

the attachment portion includes a rotation support portion that is located inside the insertion opening, is configured to engage with a tip portion of the insertion portion in an insertion direction into the insertion opening, and is configured to rotatably support the nose pad about the tip portion.

4. The head-mounted display apparatus according to claim 3, wherein

the insertion portion includes

a shaft portion that extends along the first axis when viewed from the first direction, and is supported by the rotation support portion to serve as a rotational movement shaft of the nose pad,

two first extending portions extending in the first direction from a first end side and a second end side of the shaft portion, and

two second extending portions respectively extending, in directions that are away from each other, from sides of the two first extending portions opposite from the shaft portion, and

at least one second extending portion of the two second extending portions is locked by one of the first locking portion and the second locking portion.

5. The head-mounted display apparatus according to claim 4, wherein

each of the first locking portion and the second locking portion is a recessed portion into which the two second extending portions fit.

6. The head-mounted display apparatus according to claim 4, wherein

the attachment portion includes a regulating portion that is located between the first locking portion and the second locking portion, and is configured to abut the two second extending portions to regulate rotation of the nose pad.

7. The head-mounted display apparatus according to claim 4, wherein

the two second extending portions have flexibility such that the two second extending portions move toward and away from each other.

8. The head-mounted display apparatus according to claim 1, wherein

the nose pad includes

a first nose rest portion and a second nose rest portion,

a first rocking support portion that rockingly supports the first nose rest portion,

a second rocking support portion that rockingly supports the second nose rest portion,

a first connecting portion that couples the insertion portion and the first rocking support portion, and

a second connecting portion that couples the insertion portion and the second rocking support portion, and

at least one connecting portion of the first connecting portion and the second connecting portion includes

a first component extending in a direction away from the insertion portion,

a second component extending from the first component in a direction that intersects each of a direction parallel to a first axis connecting the first nose rest portion and the second nose rest portion and an insertion direction of the insertion portion with respect to the attachment portion, and that is directed from the insertion portion toward a nose rest portion, coupled to the at least one connecting portion, among the first nose rest portion and the second nose rest portion,

a third component being bent with respect to the second component in a direction along an extending direction of the second component and away from the insertion portion, and

a fourth component that extends from the third component, and is coupled to a rocking support portion, coupled to the at least one connecting portion, among the first rocking support portion and the second rocking support portion.

9. The head-mounted display apparatus according to claim 1, wherein

the display unit includes

a left-side light guiding unit configured to guide left eye image, and

a right-side light guiding unit configured to guide right eye image,

the support portion includes a frame that supports the left-side light guiding unit and the right-side light guiding unit, and

the attachment portion is located between the left-side light guiding unit and the right-side light guiding unit, and attaches the left-side light guiding unit and the right-side light guiding unit to the frame.
