<p><P>PROBLEM TO BE SOLVED: To eliminate inconvenience of passively opening/closing a lid in a case module of an auto-folder function automatically controlling the opening/closing of the lid of the case having a storage space. <P>SOLUTION: This case module includes a motor 200 or 300 enabling the rotation of the lid, the case opening the lid when turning on a normal rotation switch 230 or 331 and closing the lid when turning on an inverse rotation switch 240 or 340, a buffer emitting a normal rotation signal or an inverse rotation signal according to turn-on of the normal rotation switch or the inverse rotation switch respectively, and a driving section rotating the motor according to the input of the signal by the buffer; and a control method of the case lid rotation. This case module, for eliminating the inconvenience of passively opening/closing the lid, controls the normal rotation and the inverse rotation of a DC motor using a driving circuit and executes the function of opening/closing the lid according to the rotation of the DC motor. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
