Description
Vynález sa týká spísobu reflexnej reprodukcie originálu na. svetlocitlivú vrstvu.The present invention relates to a method for reflective reproduction of an original on a. light-sensitive layer.
Známe zariadenia na zhotoveníe reprodukcie z nepriestvitných originálov používajú pre premietanie obrazu z originálu na kópiu, resp. matricu - negativ optické a mechanické přístroje - objektivy, zrkadlá, clony, uzáviery, attf. Takéto zariadenia sú poměrně zložité, náročné na výrobu a drahé.Known devices for making reproductions from opaque originals use an image to be copied or copied from the original. matrix - negative optical and mechanical instruments - lenses, mirrors, shades, closures, attf. Such devices are relatively complex, expensive to manufacture and expensive.
Vyššie uvedené nevýhody sú odstraněné reflexnou reprodukciou originálu na svetlocitlivú vrstvu pódia vynálezu, ktorého podstatou je, že sa medzi originál a svetlocitlivú vrstvu vloží svitlovodivá folia, ktorá je opatřená z oboch stráň nepriesvitnou vrstvou, přerušenou v mieste, v ktorom je vo fólii vytvořená polopriepustná zrkadlová plocha. Svetlovodivá folia sa rovnoměrně pohybuje tak, že polopriepustná zrkadlová plocha přejde po celej ploohe originálu a svetlovodivou fóliou prichádzajúce lúče, po odraze od polopriepustnej zrkadlovej plochy, postupné osvetlia celý originál a po odraze od jeho povrchu a přechode cez polopriepustnú zrkadlovú plochu vytvoria v svetlocitlivej vrstvě latentný zrkadlový obraz originálu.The above-mentioned disadvantages are eliminated by reflective reproduction of the original on the light-sensitive layer according to the invention, which consists in inserting between the original and the light-sensitive layer a light-transmissive foil, which is provided with an opaque layer area. The light-guiding foil moves evenly so that the semi-transparent mirror surface passes over the entire area of the original and the incoming beams pass through the light-transmissive film, after reflection from the semi-transparent mirror surface, gradually illuminates the whole original mirror image of the original.
Výhodou spSsobu pódia vynálezu je to, že obraz z originálu sa na svetlocitlivú vrstvu premieta priamym odrazom světelných lúčov od originálu osvětleného pomocou polopriepustnej zrkadlovej ploohy bez použitia drahých objektívov a inýoh zložitých prístrojov.An advantage of the method according to the invention is that the image from the original is projected onto the light-sensitive layer by direct reflection of the light rays from the original illuminated by a semipermeable mirror plate without the use of expensive lenses and other complex instruments.

Na originál 1 a grafickou informáoiou, napr. textom 2t 3® přiložená kopla 2 so svetlocitlivou vrstvou 4» ktorá je obrátená k originálu 2,. Medzi originál a kópiu je vložená avetlovodivá folia 2» opatřená na ploché obrétenej ku kopii i k originálu nepriesvitnou vrstvou přerušenou v mieste, v ktorom je vo fólii 2 vytvořená polopriepustná zrkadlová plocha 2· Světlo znázorněné lúčom ktoré je přivedené fóliou 2» aa čiastočne odrazí od polopriepustnej zrkadlovej plochy 2 na originál 1 a po odraze od textu 2 čiastočne přejde cez polopriepustnú zrkadlovú plochu 2 na svetlocitlivú vrstvu 4 kopie J, kde vytvoří latentný obraz textu.On the original 1 and graphical information, e.g. The copol 2 with the photosensitive layer 4, which is facing the original 2, is enclosed with the text 2t 3®. Between the original and the copy is inserted avetlovodivá film 2 »measures Areas Obretenov to copy also to the original opaque layer interrupted at the point in which the film 2 formed a semi-transparent mirror surface 2 · Light depicted beam that is fed sheet 2" AA partially reflected by a semipermeable the reflective surface 2 to the original one, and after reflection from the text part 2 passes through a semipermeable mirror surface 2 on the light-sensitive layer of the copy J 4, wherein the formed latent image of the text.
Použitie sptfsobu reprodukcie podía vynálezu je výhodné pre jednoduchost zariadenia, napr. v prenosnom vyhotovení a pre zhotovenie transparentných kopií, resp. matric menej náročných originálov, napr. listin s textom. Spfisob reprodukcie podía vynálezu je možné realizovat napr. fotografiokou cestou a získaná transparentně matrica umožní dřalšiu kontaktnú reprodukoiu napr. diazografiou. Tento spfisob je tiež vhodný pre elektrogrefiu, ktorou sa získajú priamo kopie.The use of the reproduction method according to the invention is advantageous for the simplicity of the device, e.g. in portable design and for making transparent copies, respectively. matrices of less demanding originals, e.g. documents with text. The method of reproduction according to the invention can be realized e.g. photographically and the transparent matrix obtained allows further contact reproduction, e.g. diazografiou. This method is also suitable for electrogression to obtain copies directly.
