PROBLEM TO BE SOLVED: To easily superimpose videos from plural liquid crystal projectors without deviation by stacking plural unitized projector supporting bases and connecting an inclination and right-and-left direction adjusting mechanism for a placing plate to all the supporting bases or the supporting bases except one. SOLUTION: This device is provided with the placing plate 2 on which the liquid crystal projector is placed, and plural unitized supporting bases 1 are stacked and the inclination and the right-and-left direction adjusting mechanism for the plate 2 is connected to all the supporting bases or the supporting bases except one. Since the plate 2 of the supporting base 1 can be adjusted in terms of inclination and in the right-and-left direction each liquid crystal projector set on the plate 2 is singly adjusted in terms of the inclination and in the right- and-left direction. Therefore, the videos from the respective projectors are superimposed on a screen without deviation. Since one projector being reference need not be always adjusted in terms of inclination and in the right-and-left direction, the inclination and right-and-left direction adjusting mechanism is omitted.
