<P>PROBLEM TO BE SOLVED: To provide an automatic opening and closing apparatus which has a simple configuration, which can give an alarm by monitoring an operation of an opening and closing body in an undriven state without being provided with a sensor and the like, by the automatic opening and closing apparatus itself, and which can be easily interlocked with another system. <P>SOLUTION: An automatic opening and closing apparatus 100 for sliding an opening and closing body 101 in a reciprocating manner along a rail 110 includes a control section 120 which drives and controls a linear motor comprising a movable element 112 and a stator 111. The control section 120 comprises detection means 121 for detecting an electromotive force generated by the movement of the movable element 112 when the linear motor is not driven, setting means 122 for setting conditions, and alarm means 123 for giving an alarm depending on the conditions and the detected electromotive force. <P>COPYRIGHT: (C)2013,JPO&INPIT |
