Abstract

La presente invenzione riguarda un dispositivo per generare un segnale elettrico in risposta a movimento di un oggetto (1) presso un punto predeterminato o entro un'area predeterminata, almeno tre elementi fotosensibili (4, 5, 6) posizionati mutuamente fianco a fianco nel percorso di movimento dell'oggetto (1) si sposta presso gli elementi (4, 5, 6) in sequenza l'uno dopo l'altro, che una sorgente di luce (2) è disposta per illuminare gli elementi fotosensibili (4, 5, 6) direttamente oppure indirettamente attraverso un riflettore (3), che i tre elementi fotosensibili (4, 5, 6) sono accoppiati ad un circuito (12-15) di elaborazione di segnali per valutare i segnali dai medesimi, e che i due elementi fotosensibili esterni (4, 6) sono accoppiati ciascuno al loro amplificatore differenziale (12, 13), mentre l'elemento fotosensibile intermedio (5) è accoppiato a riferimento a entrambi gli amplificatori differenziali (12, 13).
