ABSTRACT:
In order to facilitate pupil distance adjustment, diopter adjustment and convergence adjustment, in a spectacle type display arrangement which utilizes of a pair of image generating units for projecting images on left and right eyes respectively, a pair of shafts are installed in a housing by way of a frame, and a pair of lens and mirror units are reciprocally mounted on the shafts so as to movable toward and away from each other. A slide plate which forms part of a backlight is disposed on the frame so as to be slidable in the fore-and-aft direction. A pair of shafts are disposed one above the other at the upper and lower portions of the backlight. A pair of LCD holders which form a part of the pair of image source means are supported on the shafts so as to be laterally movable toward and away from each other. A pupil distance adjustment of the pair of image generating means is implemented by a rotation of a knob 8 through cam and link mechanisms, while a diopter adjustment and a convergence adjustment are simultaneously implemented by a rotation of a knob through a separate cam mechanism.
