DISPOSITIVO PER LA TRASMISSIONE DI SEGNALE NONCHE' APPARECCHIO CON TRASMISSIONE DI SEGNALI OTTICI SENZA CONTATTO

摘要

The arrangement comprises a light emitter (17), which transmits the light signals to a circular light conductor (18) relative to the light emitter. An input or output surface (21) is provided, which is formed at the light conductor guided out from the contour of an annular body (19). An independent claim is also included for a floor dust collecting device for contactless transmission of optical signals.
