装置。[Scope of Claim for Utility Model Registration] An overhead projector OHP, etc. is arranged in the center of the back of the screen 1, and an overhead projector O is arranged further behind the overhead projector OHP, etc.
Reflective plates 2, 2 are arranged symmetrically in a V-shape with the HP etc. as the center, and the parallel line between the reflective plates 2, 2 and the screen 1 is Y-
The angle α formed with Y is projected onto the reflectors 2, 2 from an overhead projector OHP, etc.
Projected from the back using an overhead projector or the like, the center of the image is set to coincide with the center line XX of the screen 1 when the image is reflected and formed on the screen 1. Screen devices such as overhead projectors that use images from the surface.
