reinforcing panel, wherein a front panel in the screen has a plane wider than residual
panels on the back of the screen, an image projector for projecting an image on
the screen, a screen frame fit on the peripheral edges of the residual back panels
with a plane smaller than the front panel, a double-side adhesive tape inserted
between residual back panels and the screen frame for uniting them together, a
single-side adhesive tape applied across the peripheral edges of the front panel
and the screen frame for uniting them together, and a housing for accommodating
therein the image projector and for holding at its opening the screen via the screen
