For this reason, in the conventional louver type blind, it is necessary to use the lighting even in the daytime when the blind is shaded.
  • the heat of the sunlight radiated to the slats is accumulated in the slats, and the slats tend to become hot, and are accumulated in the slats during the hot outdoors such as summer. It also has the disadvantage that the heat is radiated to the indoor side where the temperature is low, and the cooling efficiency in the room deteriorates. Further, there are drawbacks that the weight of the slats becomes heavy and the mechanical portion that operates the slats is liable to break down, and that there is a risk of injury when touched by a person.

  • the blind of Patent Document 1 described above has a drawback that it is difficult to improve the accuracy of the dimensional shape of the slats. This is because, in the blinds of the same document, the slats are formed by bending the resin film into a V shape, and the resin film has strong elasticity and is not easily plastically deformed. Therefore, even if the slats are bent into a V shape, the slats tend to return to the side where the V-shaped opening becomes large (springback occurs).
