Abstract: 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).

Abstract: An optoelectronic sensor is provided comprising a focus-adjustable optics, wherein the sensor has a movable carrier element having the optics and has a fixed-position holding element as well as a focus adjustment unit that comprises a moving coil and a magnetic unit to vary the position of the movable carrier element with respect to the holding element and thus the setting of a focal position. The moving coil is here configured as a circuit board coil.

Abstract: A focusing device for an optical system that has a carrier and an objective arranged thereat comprises a first guide section that is configured for fastening to the carrier or is designed in one piece therewith, a second guide section that forms a holder for the objective, at least one spring element that forms an elastic connection of the first guide section to the second guide section, and an actuator for adjusting the second guide section in and against an adjustment direction with respect to the first guide section, wherein the spring element is areal at least regionally. The spring element has at has one stiffening zone in which a first surface section of the spring element is bent over along a bending edge with respect to a second surface section of the spring element.
