Description

Vynález sa týká spžsobu reflexnej reprodukoie originálu na evetlocitlivú vrstvu.The present invention relates to a method of reflective reproduction of an original on an evitocensitive layer.

Známe zariadenia na zhotovenie reprodukoie z nepriesvitných originálov používajú na premietanie obrazu z originálu na kópiu, resp. matrieu-negatív optické a mechanické přístroje - objektivy, zrkadlá, clony, uzávierky atď. Takéto zariadenia sú poměrně zložité, náročné na výrobu a drahé.Known reproduction machines use opaque originals to project an image from an original to a copy or a copy. matrieu-negative optical and mechanical instruments - lenses, mirrors, iris, shutters, etc. Such devices are relatively complex, expensive to manufacture and expensive.

Vyššie uvedené nevýhody sú odstránené sp8sobom reflexnej reprodukoie originálu na evetlocitlivú vrstvu, ktorého podstata spočívá v tom, že sa medzi originálom a svetlocitlivou vrstvou vytvoří medzera, ktorou sa osvětlí originál, pričom sa svetlooitlivá vrstva chrání proti priamemu dopadu lúčov osvetťujúcich originál. Odrazom lúčov od originálu na evetlocitlivú vrstvu sa vytvoří v tejto vrstvě zrkadlový latentný obraz originálu.The above-mentioned disadvantages are eliminated by the reflexive reproduction of the original on the evocitatively sensitive layer, which consists in creating a gap between the original and the photosensitive layer to illuminate the original, while protecting the light-sensitive layer against the direct impact of the rays illuminating the original. Reflecting the rays from the original onto the evasion-sensitive layer creates a mirror latent image of the original in this layer.

Výhodou sp8sobu podl’a vynálezu je to, že obraz z originálu sa na evetlocitlivú vrstvu premieta priamym odrazom světelných lúčov od originálu bez použitia drahých objektívov a iných zložitýoh přístrojov.An advantage of the method according to the invention is that the image from the original is projected onto the evitlocensitive layer by direct reflection of the light rays from the original without the use of expensive lenses and other complex instruments.

Nad originálom 1 s grafickou informáciou, napr. textom 2 je na valoovej plocha 2 umiestnená kópia J so svetlocitlivou vrstvou 4 tak, že medzi originálom a kópiou jeAbove the original 1 with graphic information, e.g. with text 2, a copy J with a light-sensitive layer 4 is placed on the valoid surface 2 so that between the original and the copy

Obraz celého originálu sa na kopii vytvoří postupné valením kopie po origináli.198 557 formed by a gap £. The light-sensitive copy layer is enclosed by the cassette J against the direct impact of the rays. The image on copy ea creates a direct reflection of the rays from the original text. An image of the entire original is created on the copy by rolling the copy after the original.

Použitie spdsobu reprodukoie pódia vynálezu je výhodné pre jednoduchost zariadenie, napr. v přenoenom vyhotoveni a pre zhotovenie transparentných kopií, resp. matric menej náročných originálov, napr. listin e textom. Spdsob pódia vynálezu je možné realizovat napr. fotografickou cestou a získaná transparentně matrica umožní cfalšiu kontaktnú reprodukciu, napr. diazografiou. Tento spdsob je tiež vhodný prs elektrografiu, ktorou sa získajú priamo kopie.The use of the reproduction method according to the invention is advantageous for the simplicity of the apparatus, e.g. in a transferred form and for making transparent copies, respectively. matrices of less demanding originals, e.g. listin e text. The method according to the invention can be realized e.g. photographically, and the obtained matrix transparently allows for a smoother contact reproduction, e.g. diazografiou. This method is also suitable for breast electrography, which directly obtains copies.

Claims

198 557 a gap formed The light-emitting layer of the copy is shielded by the cartridge J against the direct fall of the beams. The image on the copy is created by direct reflection of the rays from the original text. The use of the reproduction method of the invention is advantageous for the simplicity of the device, e.g. in transparencies and for making transparent copies, respectively. matrices of less-than-original originals, such as text documents. The method according to the invention can be realized for example. The photographic pathway and the obtained transparent matrix will allow for further contact production, e.g. by diazography. This method is also suitable for electrography, which can obtain copies directly. BACKGROUND OF THE INVENTION A method of reflecting an original on a light sensitive layer, characterized in that a gap is formed between the original and the light sensitive layer by which the original is illuminated, the light sensitive layer being protected against the direct impact of the beams illuminating the original and reflecting the beams from the original to. the light sensitive layer is formed in this layered mirror latent image of the original. 1 drawing
