Image sensor module with zooming function
First Claim
1. An image sensor module with a zooming function, comprising:
- first and second barrels for respectively holding condensing lenses used for image capture;
a housing having a guide channel at a sidewall thereof and movably and stably receiving first extensions of said first and second barrels in the guide channel such that the first and second barrels are moved along a focusing axis of the condensing lenses and are stably held at selected positions;
a motor for generating a rotating force;
a motor gear formed on an output shaft of said motor; and
means for controlling an interval between said first and second barrels by converting a rotating action of the motor gear into a linear movement of the first and second barrels in a horizontal direction.

Abstract
An image sensor module with a zooming function is disclosed. The sensor module consists of first and second barrels for respectively holding condensing lenses used for image capture, and a housing having a guide channel at a sidewall thereof and movably and stably receiving the first extensions of the first and second barrels in the guide channel such that the first and second barrels are moved along a focusing axis of the condensing lenses. The sensor module also has a motor for generating a rotating force, a motor gear formed on the output shaft of the motor, and a means for controlling the interval between the first and second barrels by converting a rotating action of the motor gear into a linear movement of the first and second barrels in a horizontal direction. In the sensor module used in a variety of electronic apparatuses, the condensing lenses are movable to change their positions, thus accomplishing a zooming effect while precisely condensing light beams to produce clear images.
