1. A cellular phone comprising:
- a body including a circuit for calls, a microphone, buttons and a pair of fixed units, the pair of fixed units which are protruded with predetermined intervals in one end of the body and have grooves formed in the opposite direction with each other;
a folder including a circuit for calls, a speaker, a display window, and a housing, wherein the housing is located and hinge-coupled between the pair of fixed units in the body and the internal side of the housing forms an enclosure;
a camera installed in the housing for rotating in the same direction with the folder, having a lens for imaging an object to the outside of the housing;
a drive unit installed in the housing for making a motor fixed-installed in the housing for making a rotating force in the forward and backward direction by the supply of voltage, and a decelerator installed in one end of the motor for increasing torques while reducing the rotating force and transferring the driving force selectively to the camera connected to an output terminal; and
a control unit for supplying electric signals to the drive unit and controlling operations, including a phase detecting part consisting of a brush and a commutator installed to correspond to the mutual-facing sides of the camera and the drive unit and electrically-connected in order to detect phases according to the rotation of the camera and output signals for controlling a supply voltage of the drive unit, and a switch applied an operating voltage from a user.
