<p>A picture display apparatus includes a left display unit and a right display unit which are arranged symmetrically, and guide pieces are provided on upper portions of the display units in a manner that the guide pieces are projected from an upper surface of an upper chassis. By engaging respective guide pieces with left and right links, and by rotating a knob, the left and right links are symmetrically slid, and an adjustment of an interval between the display units is performed. Furthermore, a lever is provided at a center portion of the upper surface of the upper chassis in a manner that the lever can be freely rotated in front and rear directions, and pins provided on left and right lens units are connected to the both ends of the lever by universal joints which can be rotated in the front and rear directions but expansible or collapsible in the left and right directions. When the lever is rotated in the front and rear directions, the pins are symmetrically moved in the left and right directions, and therefore, the display units can be simultaneously focused. <IMAGE></p> |
