Glasses type display apparatus

A glasses type display apparatus for displaying an image including left and right virtual images generated by respective left and right display means and transmitted through respective left and right lens systems, said left and right lens systems each having a corresponding focal point and each being disposed symmetrically with respect to a center point of a main point axis, said glasses type display apparatus comprising:

• moving means for moving said left and right lens systems symmetrically with respect to each other about said center point;
• slide means for moving said left and right display means along corresponding left and right segment lines, each segment line extending through said center point of said main point axis and the focal point of a corresponding left or right lens system;
• and
• linking means for operatively connecting said moving means and said slide means so that movement of said left and right lens systems by said moving means causes said slide means to move said display means along said left and right segment lines.

A glasses type display apparatus for displaying a virtual image produced using left and right lens systems and corresponding left and right display means, comprising:

• a head fitting member for supporting said left and right display means and said left and right lens systems, above a level of a user's eyes;
• a beam splitter located below said left and right lens systems and in front of the eyes of said user, said beam splitter having a predetermined inclination with respect to optical axes of said left and right lens systems;
• and
• shutter means for blocking out all of the outside field of view corresponding to a display area occupied by said virtual image.

A glasses type display apparatus comprising:

• left and right lens systems;
• left and right horizontally arranged display means which are located directly above said left and right lens systems, said left and right display means producing left and right images which are projected vertically downward from said left and right display means to said left and right lens systems;
• a beam splitter located below said left and right lens systems and in front of the eyes of said user, said beam splitter having a predetermined inclination with respect to optical axes of said left and right lens systems;
• shutter means associated with said beam splitter for blocking out all of the outside field of view corresponding to display area occupied by a virtual image created by said left and right images;
• first adjustment means associated with said left and right display means for moving said left and right display means diagonally with respect to said left and right lens systems so that as the distance between said left and right display means and the left and right lens systems increases the distance between the left and right display means also increases;
• and
• second adjustment means for adjusting the distance between said left and right lens systems by moving said left and right lens systems laterally with respect to each other, said second adjusting means being operatively connected with said first adjusting means so that as the distance between said left and right lens systems varies diagonal movement of said left and right display means is induced.
