Claims

[Claims for Utility Model Registration] (1) An electric curtain driving device comprising an output gear having a drive pulley for opening and closing the electric curtain, and driving the electric curtain to open and close by rotation of the output gear, the output a drive motor that generates rotational force of the gear; a drive gear connected to the drive motor; a first lever rotatably supported on a support shaft of the drive gear; and a state in which each lever meshes with the drive gear. and a pair of clutch gears provided at symmetrical positions with respect to the spindle of the first lever, and when one of the clutch gears meshes with the output gear in the first position, the drive motor rotates. transmitting force to the output gear and the second
a clutch mechanism that disengages from the output gear at a position to release the transmission of the rotational force; a torque applying mechanism that applies rotational motion about the support shaft to the clutch gear; and a return mechanism that returns the clutch gear to the second position by driving for a predetermined period of time after the drive motor has stopped, and the clutch gear meshing with the output gear is switched to either one depending on the rotational direction of the drive motor. A driving device for an electric curtain, characterized by comprising: (2) The return mechanism includes an electromagnetic solenoid that is driven for a predetermined time after the drive motor stops, and a second lever that is driven when the electromagnetic solenoid is driven, and further includes a 2. The clutch gear according to claim 1, wherein a cam means is provided on the second lever, and when the second lever is driven, the first lever is rotated by the cam action to return the clutch gear to the second position. Electric curtain drive device.
