DEVICE FOR DRIVING LENS OF CAMERA TO CHANGE POSITION OF POWER TRANSMISSION MEMBER IN VARIOUS DIRECTION BY CONNECTING LENS MODULE WITH LEAD SCREW

摘要

PURPOSE: A lens driver for a camera is provided to overcome the assembling errors between a lens module and a lead screw by improving a structure. CONSTITUTION: A lens module contains a lens(23) and a slider(21). A power transmission member is loaded in the installation portion to be movable. The installation portion has a through-groove and a slit groove. The through groove is supported by inserting one end of the power transmission member. The slit groove is supported to be movable at perpendicular to a moving direction of the slider. The power transmission member to connect the lens module with a lead screw has the degree of freedom to be changeable in many directions. Thereby, the friction load between the lead screw and the power transmission member is reduced. Therefore, the current consumption of a driving motor is minimized and the noise by the friction is reduced.
