Case module having auto-folder function and control method thereof

A motor that enables the rotation of the lid, and turn-on of the forward rotation switch (turn on) when the case cover the turn-on of the cover when the cover opens, the reverse rotation switch; Buffer (buffer) for generating a respective forward rotation signal or a reverse rotation signal, depending on whether the turn-on of said forward rotation switch or said reverse rotation switch; And to a case and the case cover rotation control module comprises a driving portion to the signal in the buffer as the input rotation of the motor. To eliminate inconvenience that the manually open and close the cover by using a driving circuit will be to control the forward and reverse rotation of the DC motor and the cover to perform the opening and closing function in accordance with the rotation of the direct current motor. Case, motors, and the switch, rotation
