Claims

[Scope of utility model registration request]

A spring is wound around the outer circumference of a fixed shaft, one end is fixed to the fixed shaft, the other end is fixed to a hoisting wheel around the fixed shaft outer circumference, and supports a hanging load in proportion to the descending length of the slat curtain. In a slit type shutter, the upper end of the curtain is fixed in a slit type shutter, which is equipped with a curtain having slits in the mutually slidable extensions of each slat connected to the shutter so as to be slidable thereon, and in which the slit is fully opened when the curtain is in contact with the ground. a movable ratchet that is integrated with the hoisting wheel and that automatically rotates about the fixed shaft; a fixed ratchet that is fixed coaxially with the fixed shaft and that reverses the direction of the movable ratchet and its teeth; an operating wheel provided coaxially and rotatably with the fixed shaft between the movable ratchet and the fixed ratchet; and an operating wheel provided parallel to the fixed shaft and rotatably passing through the operating wheel in the axial direction. a pawl shaft having a movable pawl that engages with the movable ratchet at its end on the movable ratchet side, and a fixed pawl that engages with the fixed ratchet at its end on the fixed ratchet side; drive operation means for rotationally driving the operating wheel, and the angular phase of the movable side pawl and the fixed side pawl is such that when one of them engages with the corresponding ratchet, the other disengages from the corresponding ratchet. The opening and closing mechanism of the slit-type shutter is set to .
