Portable electronic apparatus and camera module

A camera module comprising:

• a carrier configured to move in an optical axis direction;
• a frame and a lens holder disposed in the carrier in the optical axis direction and configured to move together with the carrier in the optical axis direction;
• a lens barrel fixedly inserted into the lens holder;
• a first ball member disposed between the carrier and the frame, and configured to guide the frame in such a manner that the frame and the lens holder move in a first axis direction perpendicular to the optical axis direction;
• a second ball member disposed between the frame and the lens holder, and configured to guide the lens holder in such a manner that the lens holder moves in a second axis direction, perpendicular to the first axis direction;
• and
• a third ball member disposed between the carrier and the lens holder and configured to support the movements of the lens holder in the first axis direction and the second axis direction,
• wherein the third ball member has more contact points with the carrier than the first ball member.

A camera module, comprising:

• a carrier movable in an optical axis direction;
• a first ball member disposed on the carrier and rotatable in a first axis direction substantially perpendicular to the optical axis direction;
• a frame movable on the first ball member in the first axis direction relative to the carrier;
• a second ball member disposed on the frame and rotatable in a second axis direction different from the first axis direction;
• a third ball member disposed on the carrier, exposed through the frame, and rotatable in the first direction and the second direction;
• and
• a lens holder movable on the second and third ball members in the second axis direction relative to the frame,
• wherein the third ball member has more contact points with the carrier than the first ball member.
