Springs 28, 29 are disposed in the front barrel 26 and rear barrel 27. As a result of this, when a release button is pushed, the drive motor 6 runs, causing the front barrel 1 pulley 2 to be revolved by the clutch mechanisms 7, 17. The front curtain 3 and rear curtain 4 then travel. Thence, the drive motor 6 runs reverse and the front curtain 3 and rear curtain 4 are wound to the front barrel 26 and rear barrel 27 by the springs 28, 29.
