<P>PROBLEM TO BE SOLVED: To provide a motor driving device capable of bringing only one opening/closing section into a locked state and making the other opening/closing sections continue to be opened/closed, when the plurality of opening/closing sections are simultaneously opened/closed. <P>SOLUTION: A control section 2 determines whether or not each of motors M1, M2... is in a locked state. In the case where a plurality of MOSFETs Q1, Q2... are in an on-state and where the locked state of the one motor such as the motor M1 among the motors M1, M2... is detected, a switch in the on-state among the MOSFETs Q2, Q3... associated with the motors M2, M3 is intermittently turned on/off. <P>COPYRIGHT: (C)2012,JPO&INPIT |
