Image Display device
First Claim
1. Head worn image display device, particularly for displaying TV pictures, having a screen (4) or image holder being arranged in front of the ridge of nose or the middle part of the forehead of the person wearing the device, in the theoretical imaginary median plane of the head (1), perpendicularly to said median plane, said device comprisinglight beam dividing optical elements (8,9) having reflecting surfaces symmetrical in relation to said median plane (x) of the user'"'"'s head (1) and dividing said light beam into beam branches (f1, f2) and directing them towards the user'"'"'s eyes;
- optical elements (12,13) reflecting said beam branches (f1, f2) into the pupils (14,15) of the user'"'"'s eyes; and
focusing elements (16,17) characterized bya first light beam reflecting optical element (10) directing the light beam starting outwards from the screen (4) or image upwards or downwards in relation to the user'"'"'s head; and
a second light beam reflecting optical element (11) directing the light beam starting from said first reflecting optical element (10) to said light beam dividing optical elements (8,9).

Abstract
A head worn image display device, particularly TV picture display device, includes a TV screen or an image holder, and optical elements for transmitting a light beam from the screen or image to the eyes. The essence of the invention is that the device comprises optical elements dividing the beam starting from the screen (4) or image into beam branches, and directing the beam branches towards the eyes of a user of the device; optical elements reflecting the beam branches into the pupils (14,15); and focusing elements arranged between the reflecting optical elements and the pupils, and/or between the dividing optical elements and the reflecting optical elements.
