Head-mounted image display apparatus
First Claim
1. A head-mounted image display apparatus wherein images from a pair of image display means provided in a device body are respectively provided to left and right eyes of a user in enlarged form, each image passing along an optical path including a reflector means disposed between a respective image display means and an ocular lens corresponding to each respective left and right eye, comprising:
- a pair of optical visual units, each visual unit respectively housing one of said image display means, said reflector means and said ocular lenses; and
mounting means for adjustably mounting said pair of optical visual units along a horizontal direction. Wherein said optical visual units are respectively movable toward and away from each other along the horizontal direction, and each of said image display means is independently movable with respect to its respective optical visual unit;
further comprising focusing means for moving each image display means in a vertical direction perpendicular to the horizontal direction relative to said respective optical visual unit.

Abstract
A head-mounted image display apparatus includes optical visual units mounted on a laterally disposed shaft and adjustable so as to be movable toward and away from each other for establishing a correct eye spacing for a user. LCD display panels are mounted within the optical visual units so as to be vertically movable while ocular lenses onto which images displayed by the LCDs are projected via an obliquely arranged mirror are positionally fixed relative the eyes of the user such that focus adjustment will not cause image dropout and so that focus and eye spacing may be established independently of each other. Sliders provided for effecting focus and eye spacing adjustment are mounted such that frictional force is applied thereto for providing smooth but sure movement of the sliders so that a set position of the sliders may be reliably maintained. The sliders may be mounted via self a lubricating mounting to improve adjustment smoothness and slide characteristics.
