Abstract

Provided is a head-mounted display apparatus including a frame extending in a first direction, a display unit configured to emit image light in a second direction intersecting the first direction, a casing attached to one end, in the first direction, of the frame and housing a part of the display unit, and a temple portion arranged on a center side of the head-mounted display device, in the first direction, with respect to the casing. The casing includes a side surface positioned on a side on which the temple portion is arranged, and a first recessed portion, in the side surface, opening in the second direction to form a first gap with the temple portion that is arranged along the side surface.

First claim

What is claimed is:

1. A head-mounted display apparatus comprising:
a frame extending in a first direction;
a display unit configured to emit image light in a second direction intersecting the first direction;
a casing attached to one end, in the first direction, of the frame and housing a part of the display unit; and
a temple portion arranged on a center side of the head-mounted display device, in the first direction, with respect to the casing, the temple portion having an outside surface in the first direction, wherein
the casing includes:
a side surface positioned on a side on which the temple portion is arranged; and
a first recessed portion, in the side surface, opening in the second direction to form a first gap separating the outside surface of the temple portion and the side surface of the casing, the outside surface of the temple portion being arranged along the side surface,

wherein the first gap abuts first recessed portion in the first direction.

2. The head-mounted display apparatus according to claim 1 , wherein
the temple portion, in a state of being arranged along the side surface, includes a second recessed portion into which a part of the casing is fitted.

3. The head-mounted display apparatus according to claim 1 , further comprising:
a protruding portion protruding from the outside surface of the temple portion and abutting the side surface, the protruding potion being configured to rotate the temple portion and having elasticity.

4. The head-mounted display apparatus according to claim 3 , wherein
the temple portion includes an opening surrounding a part of the protruding portion.

5. The head-mounted display apparatus according to claim 1 , wherein
the casing includes a temple support portion provided to the side surface and configured to support the temple portion,
the temple portion includes a first coupling portion and a second coupling portion sandwiching the temple support portion in a third direction intersecting the first direction and the second direction and supported by the temple support portion,
the temple support portion includes:
a first attaching portion to which the first coupling portion is attached; and
a second attaching portion to which the second coupling portion is attached, and

a second gap is formed between the first attaching portion and the second attaching portion in the third direction.

6. The head-mounted display apparatus according to claim 1 , wherein
the display unit includes:
an image emitting unit arranged in the casing in the second direction and configured to emit the image light; and
a light-guiding unit arranged in the first direction and configured to guide, to a predetermined viewing position, the image light emitted from the image emitting unit.

7. The head-mounted display apparatus according to claim 6 , wherein
the casing includes a temple support portion provided to the side surface and configured to support the temple portion, and
the temple support portion is arranged in a direction being opposite to the second direction from a center, in the second direction, of the side surface.

8. The head-mounted display apparatus according to claim 6 , wherein
the frame is formed of metal, and
the image emitting unit is fixed to the frame.

9. The head-mounted display apparatus according to claim 6 , wherein
the casing includes an inner casing provided in the casing, and
the inner casing includes a raised portion positioned between the image emitting unit and the side surface.

10. A head-mounted display apparatus comprising:
a frame extending in a first direction;
a display unit configured to emit image light in a second direction intersecting the first direction;
a casing attached to one end, in the first direction, of the frame and housing a part of the display unit; and
a temple portion arranged on a center side of the head-mounted display device, in the first direction, with respect to the casing, the temple portion having an outside surface in the first direction, wherein
the casing includes:
a side surface positioned on a side on which the temple portion is arranged, the side surface including:
an abutting surface abutting the temple portion; and
an inclined surface separating away from the temple portion in the second direction; and

a first recessed portion, in the side surface, opening in the second direction to form a first gap separating the outside surface of the temple portion and the side surface of the casing, the outside surface of the temple portion being arranged along the side surface,

wherein the first gap abuts first recessed portion in the first direction.
