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. 2
