PROBLEM TO BE SOLVED: To arbitrarily display information showing a state when any abnormality occurs and information showing the state of equipment connected by a simple structure. SOLUTION: A control means controls the opening/closing operations of an opening/closing body means according to signals from a push button means having an opening button, a stop button, and a closing button, an obstacle sensing means detecting an obstacle during opening/closing operation, a limit switch means detecting the upper limit/lower limit of the opening/closing body means, and a protector means installed in a motor. A display means displays the state of the signals outputted from these equipment. When an indicator formed of 7-segments is used, for example, as the display means, the input state of the signals can be displayed by using the same display part by corresponding the display mode of each segment to each signal outputted from a control operation indication means. Also, the display means displays the type of the abnormality when the abnormality occurs and the number of times of the opening/closing operations. COPYRIGHT: (C)2005,JPO&NCIPI
