摘要

The multi surface projection screen has two rolls of screen material mounted side by side in a common housing and clipped to a single upright support (11). Either screen can be pulled out and clipped to a hook (14) at the top of the support. The screens are double sides so that a choice of four different projection surfaces is provided. The multi screen folds into a lightweight, compact package. The upright support is telescopic and with folding legs. The screen housing clips to the upright on removable clamps while the upper clamp holds the screen in the selected orientation.
