摘要： The present invention relates to an automatic opening/closing device for umbrella, of the type that provides an electric motor (9), through which it acts on a spool system (25), which provides a wire (4) connected to the cover frame, which determines its opening and closing. Said automatic opening/closing device provides that in the spool (25) a device (40) is housed, advantageously consisting of a magnet, the position of which is detectable through a first sensor (26), capable of accurately determining the number of revolutions performed by such spool (25).
