Abstract
PURPOSE: To let shutter curtains travel by small driving force and at a constant speed by using clutch mechanisms and springs.
CONSTITUTION: A clutch mechanism 7 provided with a solenoid 10, gears 12, 13 are brake member 16 is provided between a drive motor 6 and a front barrel 1 for front curtain and a clutch mechanism 17 provided with a solenoid 19, gears 21, 22 and brake member 25 between the drive motor 6 and a winging pulley 2 for rear curtain, respectively. 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.
