Reading method and reader for an optical code

摘要

Reading method for an optical code (10) by means of a reader which comprises photoemitters (7), photoreceivers (12) and a processor circuit (52), in which the following steps are carried out: emitting a radiation (F) towards the exterior of the reader (1); detecting (110) the presence of at least one operating condition of the reader (1); activating (100) a first operating mode in the absence of the operating condition of the reader (1); and activating (110) a second operating mode (120) on detection of the operating condition. <IMAGE>
