  The Venetian blind is structured to be opened and closed by a lifting cord inserted into a guide hole formed in each slat of a plurality of plates connected by a ladder cord (connection chain).

  For this reason, in a Venetian blind in which the front and back surfaces of a slat are covered with a cloth, even if an attempt is made to remove the cloth to be covered and wash it, or to replace it with another cloth and renew the design, the lifting cord is pulled out and the slat is removed from the ladder cord. It is necessary to remove the cloth, replace the cloth, attach it to the ladder cord again, and reinsert the lifting / lowering cord. The operation is very complicated, and it is virtually impossible to remove the cloth.

  And since the slats of the Venetian blind have a both-end support beam structure in which both ends thereof are received by a ladder cord, the intermediate portion between the ladder cords at both ends is easily bent or bent during use. .

  For this reason, when the solar cell element is incorporated in the slat, the slat is bent and the electrode is easily broken. And since the electrode of a solar cell element is interrupted | blocked by the guide hole drilled in order to penetrate the raising / lowering code | cord | chord, the electrode cannot be continued from the end of a slat. In addition, the lead wire connecting the solar cell elements of each slat is not flexible like a ladder cord, and when the slat is lifted and the Venetian blind is opened, the lead wire protrudes in a ring shape. The appearance of the Venetian blind is impaired by the lead wire.

  Then, this invention makes it the 1st objective to coat | cover the front and back of a slat with a cover so that replacement | exchange is possible. A second object of the present invention is to incorporate a solar cell element into a slat without impairing the performance of the slat.
