Abstract: A display system includes a sheet member onto which information is input, and a position coordinate detector such as a pressure sensitive touch panel. The position coordinate detector is formed as a body separate from the sheet member and is arranged behind the sheet member. It detects the position of information input on the sheet member. A computer, to which the output data of the position coordinate detector is transferred, processes the information input to the sheet member. When the sheet member is used as a projection screen, the computer connects to a projector to project the input information onto the sheet member.

Abstract: In order to provide an inexpensive and compact film-transferring device, the present invention has the following features: In a film-transferring device comprising; a feed reel 1 around which a film-transferring tape a having a film applied to a surface thereof is wound and a take-up reel 2 for taking up used portion a′ of said film-transferring tape a, housed in a case body 3; and a film-transferring head 4 projecting outside the case body, for travelling on the film-transferring tape stretched between said two reels 1, 2 while pressing the tape against a film-receiving surface S: the present invention further comprises; a support axis 5 provided in said case body 3; an axial cylinder 7 combined with a reel body 8 to constitute said take-up reel 2 as a whole and rotatably mounted on said support axis 5; a transmissive plate rotatably mounted on said axial cylinder 7; said feed reel being rotatably mounted on said axial cylinder 7 in such manner as to press said reel body 8, via said transmissive plate
