Miniature auto focus piezo actuator system

The present invention offers the actuator system for 合焦 (ing) an optical image scanner automatically. Moreover, technology applicable to the design of the imaging engine relevant to a image scanner and an imaging lens system is offered. More particularly, the present invention relates to the lens guidance assembly object and actuator system for automatic 合焦 of the object lens relevant to the image processing system of the optical image scanner. As for an optical image scanner, it is desirable that it is an optical code image scanner for carrying out imaging of the optical codes, such as a bar code.
