摘要

The screen (20) has a rollable projection cloth (22) forming a small and rectangular projection surface (28), where the cloth extends in a vertical plane in unrolled position. A rolling unit is used for rolling the cloth. The cloth is provided with a ballasting bar (24) that assists to unroll the cloth and provides vertical tension to the cloth by gravity. A guiding unit formed of sliding blocks (25) sliding in a guiding rail (26) and a lateral tension unit i.e. elastic unit (29), of the cloth are integrally provided on side walls (38), and are placed face to face and normal to the cloth.
