PURPOSE:To provide a device which can project an erecting real image by providing focusing type optical transmission bodies at both side ends of the object surface and projecting surface of an optical transmission fiber system having flexibility and successively connecting these in close contact with each other. CONSTITUTION:An inverted real image 9' is passed through a focusing type optical transmission body 22 of z/2 length positioning at a distance l1 from an object 9, then through an optical transmission fiber system 3, and through a focusing type optical transmission body 22' of z/2 length and is formed on a photoreceptor 7 at a distance l1. The total length (z) of these optical transmission bodies 22, 22' is so determined that the sizes of the object 9 and the image 9' assume unmagnified sizes of 1:1. A multiplicity of the elements consisting of these focusing type optical transmission bodies 22, optical transmission fiber bundles 3 and focusing type optical transmission bodies 22' are arranged on a straight line in close contact with each other, whereby the projector is provided. |
