Abstract
An apparatus and method for the recognition of codes has a light transmitter for the transmission of light signals in the direction of a scanning region, a light receiver for the reception of a light signal remitted from the scanning region, and a control and evaluation unit for the control of the light transmitter and the light receiver and for the determination of a code from the light signal received. The control and evaluation unit includes a trigger circuit triggering the determination of a code and a distance determination unit or image detection unit (which acts on the trigger circuit) for the detection of an object present in the scanning region which is integrated into the apparatus.
