Abstract
An imager module for an optical code reader may include a camera comprising a lens system, and an actuator for moving the lens system operatively connected to the lens system for autofocus adjustment. The actuator for moving the lens system comprises a linear electric motor with a drive shaft, a position sensor device adapted to detect the position of the drive shaft within a predefined stroke length and a control device adapted to control the movement of the drive shaft. The control device and the position sensor device are integrated in a single PCB, the electric motor comprises a frame that supports the drive shaft, and the single PCB constitutes part of said frame. On optical code reader may include such an imager module.
