PURPOSE: A blind device of a dual motional structure is provided to rapidly switch an opening function and a closing function, thereby obtaining a high functional product with reliability in respect to operation. CONSTITUTION: A blind device of a dual motional structure includes first and second inclination codes (31, 32), an inclination driving device (40), and a rewinding member (50). The first and second inclination codes separately support first and second light shielding blades (11, 12). The inclination driving device rotates an inclination shaft (43) by pulling an inclination rope (41) forward and backward. The rewinding member places an inclination rewinding roll on the inclination shaft, thereby rewinding the first and second inclination codes. The rewinding member performs the inclination movement of the first and second light shielding blades by being interlocked with the rotation of the inclination rope. The first inclination code supports the first light shielding blades of odd number rows to be interlocked, and the second inclination code supports the second light shielding blades of even number rows to be interlocked. |
