Abstract: By arranging cables, which transmit video signals to a pair of video image display elements arranged on the right side and the left side, along a frame for supporting a pair of right and left light guiding devices, it is possible to concentrate the cables on one of the right and left sides. That is, it is possible to integrally form the cables. By accommodating the cables in a cable cover portion, which extends along the frame, in a cover inside, it is possible to suppress an increase in size which accompanies cable arrangement and to implement the apparatus as a whole in a small body.
