Abstract

Inventia se refera la un procedeu si la o masina electrostatica de copiat documente de tip birou, automata în constructie compacta cu subansambluri detasabile, independente de ansamblu la care copierea în varianta continua, se face printr-un adaptator fixat de masa document, cu trecere rapida de 1 o varianta de lucru la alta. Masina conform inventiei are toate subansamblurile componente fixate pe peretii laterali, care la rîndul lor sunt rigidizati cu ajutorul cadrului mobilm pe care este montat subansamblul sistemului optic. Subansamblul masa document, este adaptat pentru exploatare curenta si în acelasi timp pentru regim de mare productivitate. Masina mai cuprinde de asemenea un subansamblu tanc developare un subansamblu cuptor cu ventilator un subansamblu cuptor cu ventilator un subansamblu corotroni un subansamblu role de transport cu indexare un subansamblu traductor cu indexare, un subansamblu ghidaj pentru întoarcerea hîrtiei un subansamblu suflanta cu deflector un subansamblu programator dozator un subansamblu role de iesire. Pentru realizarea copiilor mai întîi hîrtia este încarcata pe fata cu oxid de zinc si descarcata pe cealalta fata. Apoi documentul este proiectat pe stratul fotoconductor de oxid de zinc ceea ce are ca urmare descarcarea lui în zonele iluminate si pastrarea sarcinilor în zonele obscure. în continuare cu ajutorul unui sistem lichid de relevare, se depune pe fata cu oxid de zinc a hîrtiei o pelicula de toner, încarcata electric pozitiv care este atrasa de zonele încarcate astfel încat pe fata cu oxid de zinc a hîrtiei apare imaginea documentului. în final imaginea este fixata prin trecerea prin cuptorul cu ventThe invention relates to a process and to an electrostatic machine for copying of office documents, compact in a compact construction with detachable subassemblies, independent of the whole, in which continuous copying, is done by means of a document table adapter, with a fast passage from one work to another. The machine according to the invention has all of the component subassemblies fixed to the side walls, which in turn are stiffened with the aid of the movable frame on which the sub-assembly of the optical system is mounted. The document mass subassembly is adapted for current operation and at the same time for high productivity. The machine also comprises a tank subassembly for a fan assembling subassembly a fan furnace subassembly a corotron subassembly a transport roller subassembly with an indexing transducer subassembly a paper backing subassembly a deflector blower subassembly a metering programmer subassembly an output roller subassembly. For making the children first the paper is loaded on the face with zinc oxide and discharged on the other side. Then the document is projected onto the photoconductor layer of zinc oxide which results in its discharge into the illuminated areas and keeping the loads in obscure areas. Further, by means of a liquid dyeing system, a positively charged electric toner film is deposited on the zinc oxide front of the paper, which is attracted to the areas loaded so that the image of the document appears on the zinc oxide front of the paper. Finally, the image is fixed by passing through the vent furnace
