Abstract
To provide an on-failure blind stopper system that allows reduction of depth of a head box and can be surely activated. A slider capable of moving vertically is disposed in a head box. The slider is pressed by a lifting/lowering cord and prevented from moving upward to permit a rotation shaft to rotate when the lifting/lowering cord is under tension. On the other hand, the slider moves upward to engage with the rotation shaft to prevent the rotation of the rotation shaft when the lifting/lowering cord sags.
