The present invention is related to a case module and a method for controlling the cover rotation of the case module, comprising a case, the case comprising a motor, the motor enabling a cover to rotate, said cover opening when a forward rotation switch is turned on, said cover closing when a reverse rotation switch is turned on; a buffer, the buffer generating a forward rotation signal or a reverse rotation signal, the forward rotation signal and the reverse rotation signal corresponding to the turn-on state of said forward rotation switch or said reverse rotation switch, respectively; and a driving unit, the driving unit rotating said motor, said motor using a signal from said buffer as an input. The case module and the controlling method thereof in accordance with the present invention control the forward rotation and the reverse rotation of the DC motor and have the cover open and close according to the rotation of the DC motor by use of the driving circuit such that the inconvenience of having to manually open and close the cover is eliminated.
