Zusammenfassung:	PURPOSE:To effectively restrain electric noise from occurring at operation of an electromotive curtain. CONSTITUTION:Conductors 12 on minus side and conductors 13 on plus side are arranged alternately on the stator installed in the sliding direction of a curtain, and a needle is provided with a pair of brushes 23 and 24 each abutting on the conductor 12 on minus side and the conductor 13 on plus side of this stator and a drive coil 22 supplied with an exciting current through these brushes 23 and 24. Together with it, this is provided with the first rectifier which allows the flow of a current from the electrode 10 on minus side to the drive coil 22 and interrupts the flow of current in its reverse direction, and the second rectifier 28 which allows the flow of a current form the drive coil 22 to the electrode 11 on plus side of the power source 25 and interrupts the flow of the current in its reverse direction.
