CONSTITUTION: An operation method for a blind comprises the following steps: lifting or lowering a blind sheet with the front and rear sheets overlapping each other and stopping the blind sheet at a random point; adjusting a gap between the front and rear sheets with a tilting operation; and rotating a sheet pipe at a limited angle using an operation rope (124) and loosening the blind sheet about the sheet pipe at the same angle by stopping a tilting pipe in the tilting operation. |
