PURPOSE: A method for opening/shutting a window shading adjustment-cum-motor driven shutter is provided to execute the sun shading function, to protect a window against an external object and an intruder, and to prevent the indoor invasion. CONSTITUTION: A method for opening/shutting a window shading adjustment-cum-motor driven shutter comprises the steps for detecting the signal by sensing horizontal or vertical position of a shading plate by using a position sensor, judging whether the position of the shading plate is horizontal state or vertical state, converting the shading plate into the vertical state by rotating a wheel contacted to a timing belt by driving a rotating motor(310) of a shading plate rotating unit(300) if the position of the shading plate is horizontal state, controlling the rotation of a driven roller to exclude the interference with the wheel, releasing the contact state between the wheel and the timing belt, and taking up the shading plate by moving the shading plate and the wheel toward a housing case(230) by lifting the shading plate and the wheel by using a shading plate rolling unit(200). |
