An optical code reader (10) is provided that has a light transmitter (12) having a transmission optics (14) for transmitting a reading beam (16) in a reading region (18); a focus adjustment unit (28) for focusing the reading beam (16) in a distance range; a light receiver (24) for generating a received signal from the reading beam (20) reflected in the reading region (18); and an evaluation unit (26) to read code information from the received signal. In this respect, the focus adjustment unit (28) has a pivot arm (30) that holds the transmission optics (14) at a different distance from the light transmitter (12) in dependence on the pivot position of the pivot arm (30) and that has a moving coil unit (34) to pivot the pivot arm (30).
An optical code reader, the optical code reader comprising:
A method of reading optical codes in which a reading beam is transmitted by a light transmitter through a transmission optics into a reading region and a received signal is generated in a light receiver from the reading beam received again to read code information from the received signal, wherein the transmission optics is focused by a focus adjustment unit in a distance region,
