Projection device has roller image wall with projection surface protruding from housing if unreeled; projector can be fixed in projection position in fixed relationship to unreeled projection surface

摘要

The device has a roller image wall, a projector and a housing (1). The winding shaft of the roller image wall is rotatably mounted in the housing, which encloses the image wall in the rolled up state. The projection surface of the image wall protrudes out of the housing when unreeled, whereby the projector can be fixed in its projection position by a holder in a fixed, predefined relationship to the deployed projection surface.
