Since the timing belt 5 moves in the opposite direction to the arrow because it rotates, the left curtain 2 installed in the curtain attachment 11 is completely opened while moving in the opposite direction to the stopper 13.

When the left curtain button 17b is released when the left curtain 2 is to be closed to an appropriate position in the open state, the power supplied to the motor 14 and the solenoid 15 is cut off. The right curtain (2) 3 is kept open at an appropriate position.

In addition, even in the case of opening or closing the right curtain 3 in the present invention, it is possible to open and close in the same process as the opening or closing of the left curtain (2) using the right opening and closing button (17c).

In the present invention, the timing belts 5 and 6 are coupled to the timing pulleys 27, 28, 32, 33, respectively, to prevent slippage.

According to the present invention, the curtain opening and closing device is designed and manufactured to be moved manually in the event of a power failure or a failure of the driving unit, and thus moves the left and right curtains 2 and 3 to a desired position even when the motor 14 is not operated due to the power failure or failure. The friction part is made of metal and non-metallic materials (such as synthetic resin) or non-metallic and non-metallic materials, so that smooth operation and life extension can be improved and noise can be reduced.

In the present invention, since the deceleration function, the overload interruption function, the reverse rotation function, the controller 8 and the remote controller 17 of the motor 14 are used in other industries, detailed description thereof will be omitted.
