Abstract:
1. An image capturing module comprising: a lens assembly that supports at least one lens, moves along an optical axis of light indicating an image of a subject, and comprises at least one guiding protrusion for guiding the movement of the lens assembly along the optical axis; a module supporting unit that comprises at least one guiding hole to which the guiding protrusion is inserted to guide the lens assembly, and is disposed at a rear of the lens assembly on the optical axis; a lens driving unit comprising a winding vibration type piezoelectric motor and a piezoelectric motor supporting member, wherein the winding vibration type piezoelectric motor is disposed on the module supporting unit and moves the lens assembly along the optical axis, and the piezoelectric motor supporting member supports the winding vibration type piezoelectric motor; a pressurizing member, comprising a coil spring, interposed between the piezoelectric motor supporting member and the module supporting unit; and at least one ball assembly interposed between the module supporting unit and the lens assembly.
