Besides, since the cover 310 is closed, and the push pin 341 is pressing the reverse rotation switch 340 , the reverse rotation switch 340 is in an OPEN state, thereby not generating a reverse rotation signal and not rotating the motor 300 in the reverse direction.

When the drawer 350 is inserted all the way in the case, the drawer 350 presses the forward rotation switch 331 . This makes the forward rotation switch 331 become an OPEN state. At this time, since the reverse switch 340 is in a SHORT state, an L signal is inputted to the C 2 and C 3 pins of the buffer 660 , generating a reverse rotation signal, which is then applied to the second driving unit 650 b.

  • the first driving unit 650 a rotates the motor 300 in the forward direction in accordance with the inputted forward rotation signal.
  • the cover 310 which is connected to the axle of the motor, opens in accordance with the forward rotation of the motor 300 .
  • an open signal about whether the cover open state sensing unit has detected the opening of the cover 310 to a certain angle is generated, through which it is determined whether the buffer 660 has generated a stop signal. If a stop signal is not sensed, steps S 915 -S 925 are repeated. If a stop signal is sensed, the motor 300 , which is rotating in the forward direction, is stopped in step S 930 .
  • step S 920 of the above steps the reverse rotation switch 340 opens and becomes a SHORT state, and this causes the reverse rotation switch 340 to turn on, in step S 1005 .
  • step S 1010 inserting the drawer 350 presses the forward rotation switch 331 , and this causes the forward rotation switch 331 to turn off.
  • step S 1015 the buffer 660 generates a reverse rotation signal because the forward rotation switch 331 is turned off and the reverse rotation switch 340 is turned on.
  • step S 1020 the second driving unit 650 b senses the reverse rotation signal from the buffer 660 and rotates the motor 300 in the reverse direction.
  • step S 1025 the cover 310 rotates and closes in accordance with the reverse rotation of the motor 300 .
  • step S 1030 when the cover 310 is completely closed on the upper housing 320 a, the pushi pin 341 presses the reverse rotation switch 340 , turning off the reverse rotation switch 340 . Therefore, it is determined whether the cover 310 is completely closed by checking the turn-off state of the reverse rotation switch 340 .
  • the motor 300 continues its reverse rotation because it means that the cover 300 is still not completely closed. However, if it is determined that the reverse rotation switch 340 is turned off, the reverse rotation of the motor 300 is stopped because it means that the cover 300 is completely closed.
  • 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.
