Abstract
A camera module which can switch a photographing mode of the camera module includes a housing, a holder having a lens unit and displaceable between a first position and a second position, a magnetic member and a coil, a first magnet having an N pole, and a second magnet having an S pole. Positive DC supplied to the coil magnetizes the magnetic member to an N polarity repelled by the N pole and attracted to the S pole and held at that position by stopping the current for macro photographing mode. Negative DC supplied to the coil magnetizes the magnetic member to an S polarity repelled by the S pole and attracted to the N pole and held by stopping the DC current for the normal photographing mode.
