Eyeglass-type display apparatus
An eyeglass-type display apparatus includes an eyeglass-front to be placed in front of the eyes of a user, left and right temples connected to the eyeglass-front and worn on the head of the user, a connector that adjusts the inclination of the eyeglass-front by rotating the eyeglass-front relative to the left and right temples, and an image display unit that is fixed to the eyeglass-front and projects image light onto an eyeball of the user. An axis of rotation of the connector is positioned on the eyeglass-front side of the center of the user's eyeball as viewed from the side.
1. An eyeglass-type display apparatus comprising:
an eyeglass-front having lenses to be placed in front of eyes of a user and a rim holding the lenses;
left and right temples connected to the eyeglass-front and worn on a head of the user;
an angle adjuster configured to adjust inclination of the eyeglass-front by rotating the eyeglass-front relative to the left and right temples; and
an image display unit fixed to the eyeglass-front and including an eyepiece optical unit configured to project image light onto an eyeball of the user; wherein
an axis of rotation of the angle adjuster is positioned on the eyeglass-front side of a center of the eyeball of the user as viewed from a side and the eyepiece optical unit is disposed along the rim on a side of the rim facing the user; and
the angle adjustor performs alignment adjustment by rotating the image display unit and the eyeglass-front integrally relative to the left and right temples.
2. The eyeglass-type display apparatus of claim 1 , wherein the axis of rotation of the angle adjuster is positioned near the image display unit as viewed from the side.
3. The eyeglass-type display apparatus of claim 1 , wherein the left and right temples are configured to be expandable and contractible.
4. The eyeglass-type display apparatus of claim 1 , further comprising
a nose pad to abut a nose of the user; and
a height position adjustment mechanism configured to adjust a height position of the nose pad relative to the eyeglass-front.
5. The eyeglass-type display apparatus of claim 1 , wherein a distance between the axis of rotation and the eyepiece optical unit is smaller than half of the distance from the lens to the center of the eyeball of the user.
6. The eyeglass-type display apparatus of claim 5 , wherein the distance between the axis of rotation and the eyepiece optical unit is smaller than 12 mm.
