ABSTRACT:
A blinder includes main frames spaced apart from each other with a predetermined distance. Each of the main frames has an internal empty space. Support frames are perpendicularly interposed between the main frames to support the main frames. A plurality of shutting members is arranged parallel to each other between the main frames inside the support frames. A motor is fixed to each of the main frames within the internal empty space. A driving shaft is movably connected to the motor within the internal empty space. A plurality of rotating members is fixed to the driving shaft to rotate upon receipt of a rotational power from the motor via the driving shaft. A pulling member is held between each of the opposite rotating members to keep each of the shutting members at its proper place. The pulling member is partially wound around the opposite rotating members in such a manner as to move with the rotation of the rotating member and control an opening or closing operation of the shutting member.
