It can also be configured so that a large reduction ratio can be obtained by engaging the worm gear 58b.

Unexplained reference numeral 7 denotes a buffer port and 8 denotes a curtain binding roller, respectively.

It will be described in more detail the effect of the present invention to achieve the configuration as described above.

First, the coupling and installation of the constituent members of the present invention will be outlined. The curtain automatic opening and closing device 1 of the present invention is a side of the curtain rail (2) formed in the appropriate length driving and idle wheels 52, 53 of the drive device 5 is seated in the V groove (25, 25 ') After installation, the appropriate number of curtain binding rollers 8 are seated in the V grooves 26 and 26 'so as to be exposed to the open end 22, and then both ends of the curtain rail 2 are connected to the connection port 3. And coupled with the connecting adapter 4 and the binding rod 55 of the driving device 5 and the one-side roller 8 adjacent to each other as a ring to hang on the binding groove 61 as the binding opening 6. It is installed on the ceiling surface of the window or the like, and is finished by attaching the usual curtain to the roller 8.

On the other hand, through the constant voltage circuit device built in the connection adapter 4 to form a power source for driving the present invention is output to the wire connection terminal 43, the wire not shown as the wire connector 33 of one side connector (3) To connect. At this time, the wire is embedded in the groove 21 to prevent exposure when binding. Therefore, the driving power is applied to the elastic contact 33 installed on the contact member 3 of the connector 3, and the battery B is brought into contact with the contact 54 formed on the upper end of the unit 51 of the driving device 5. Is charged to become a power source for driving the electric motor (M) through the known remote control rotary device (C) as shown in FIG.

If the remote control circuit device C is driven to open the curtain, the motor M rotates forward (assuming curtain opening direction), and this driving force rotates the ring gear 57 engaged with the bevel gear 58. Done. At the same time, the solenoid SOL is turned on to pull the disk 59 'coupled with the drive shaft 56 to pull the clutch disk 59 with the spring 57' through the magnetic force. And the clutch CL is connected to each other so that the driving force of the motor M is driven by the reduced speed of the reducer T of the ring gear 57 and the bevel gear 58. (52) is to be rotated. Accordingly, the driving device 5 is horizontally moved by the V grooves 25 and 25 'of the curtain rail 2, and the binding rod 55 moves together while pushing the roller 8 to open the curtain.

When the moved drive device 2 arrives at the end, the motor M is overloaded and sensed to stop the motor M. The shock absorber 7 is shocked by both ends of the rail and the drive device 5. To alleviate
