<P>PROBLEM TO BE SOLVED: To prevent an opening/closing body from sagging when the opening/closing body is opened fully by sensing an obstacle and then closed fully. <P>SOLUTION: In an opening/closing device, when there is a sensing signal of obstacle sensing means 12a during the feed-out rotation of a take-up body 31, the take-up body 31 is rotated for take-up and the take-up rotation is stopped in response to a sensing signal of full open sensing means. When a difference between a count value indicating a variation of the take-up body 31 and an operation origin value becomes a predetermined full close stroke value during the feed-out rotation of the take-up body 31, the feed-out rotation of the take-up body 31 is stopped. When the take-up rotation of the take-up body 31 is stopped in response to the sensing signal of the full open sensing means, processing for adjusting the timing to stop the feed-out rotation of the take-up body 31 is performed while the opening/closing body 10 is closed fully. <P>COPYRIGHT: (C)2013,JPO&INPIT |
