Abstract (en)
An electric curtain mainly utilizes a covering sheet (311) furled at an upper limit position (a), which simultaneously impels an actuating member (333) of a zero device (33) to relatively cooperate with a sensor (334) of the zero device (33), so that the covering sheet (311) would not continue operating and a counter (335) in the zero device (33) would recount once a processing unit (342) of a controlling device (34) receives a signal from the sensor (334). Thus, the processing unit (342) would drive the counter (335) to recount in every following drop of the covering sheet (311) to accurately control the suspending position without incurring an accumulative counting error and increase an operative convenience.
