Abstract

L'invenzione si riferisce ad una stampante o un simile dispositivo di uscita per produrre caratteri su un documento (2) alimentato nel passaggio di trasferimento dalla carta (1) del dispositivo, comprendente mezzi disposti in relazione al passaggio di trasferimento della carta per rivelare il documento, detti mezzi comprendono una o più sorgenti di luce (U1, U2 .... UN) e vari fotorivelatori (Q1, Q2, ....QN) posizionati lungo il passaggio al (1) di trasferimento della carta per cui il documento alimentato (2) provoca una variazione nella quantità di luce ricevuta da almeno un fotorivelatore (Q1, Q2,_ QN). Secondo, l'invenzione, per procurare una rivelazione semplice del documento malgrado l'impiego di un certo numero di fotorivelatori, i fotorivelatori (Q1, Q2,. ..QN) sono collegati in seguenza in una catena (C) in modo che una variazione nella quantità di luce ricevuta da un rivelatore provoca una variazione della corrente che fluisce attraverso l'intera catena (C), la variazione essendo rivelabile da un rivelatore di segnali (COMP) collegato alla catena.fig. 2The invention relates to a printer or a similar output device for producing characters on a document (2) fed in the device transfer passage from the paper (1), comprising means arranged in relation to the paper transfer passage to reveal the document, said means comprise one or more light sources (U1, U2 .... UN) and various photodetectors (Q1, Q2, .... QN) positioned along the passage to the paper transfer (1) whereby the fed document (2) causes a variation in the quantity of light received by at least one photodetector (Q1, Q2, _ QN). Second, the invention, to provide a simple detection of the document despite the use of a certain number of photodetectors, the photodetectors (Q1, Q2, ... QN) are connected in a sequence in a chain (C) so that a variation in the amount of light received by a detector causes a variation of the current flowing through the entire chain (C), the variation being detectable by a signal detector (COMP) connected to the chain. 2
