Beschreibung
Zusammenfassung:	Actuator systems are provided for automatically focusing an optical image reader. Techniques are also provided which are applicable to the design of imaging engines and imaging lens systems associated with image readers of various types. More specifically, the present invention relates to lens guidance assemblies and actuator systems for automatically focusing an objective lens associated with an imaging system of an optical image reader. The optical image reader is preferably an optical code image reader for imaging optical codes, such as bar codes.
