In the conventional shutter device as shown in FIGS. 3 and 6, output sprockets 41 and 412 are directly and integrally mounted on the output shafts 40 and 411 of the opening and closing machines 4 and 410, respectively. Therefore, when a trouble such as a failure occurs in the opening / closing device 4,410 and the opening / closing device 4,410 is replaced, the opening / closing device of the same type in which the output shafts 40,411 have the same configuration as the output sprockets 41,412 is mounted. I had to replace it with machine 4,410.
Further, in the opening / closing devices 4 and 410 employed in the conventional shutter device as shown in FIGS. 3 and 6, a large tension corresponding to the winding load of the shutter curtain 6 by the winding shaft 5 is passed through the conductive chain 52. Act. Since the switch 4,410 is directly subjected to this large tension, the switch 4,410 itself must be rigid enough to meet the large tension, and the cost of the switch 4,410 itself increases in size. It was high.

  Therefore, as shown in FIG. 5, the output shaft 403 and the output sprocket 401 of the switch 400 are completely separated, the output sprocket 401 is provided on the switch mounting base 701 side, and the switch 400 is mounted on the switch mounting base 801 side.

  Thus, as shown in FIG. 5 or FIG. 8, the switch and output sprocket are completely separated, so the relationship between the switch and output sprocket is that shown in FIG. 3 or FIG. 5 or FIG. 8 is gradually being transferred, and the actual shutter device is in the state where both coexist, but the switch of FIG. 5 or FIG. 8 is used as the switch of FIG. 3 or FIG. It was difficult to use.

  Further, the configuration of the output sprocket shown in FIG. 3 or FIG. 6 is often different from that shown in FIG. 5 or FIG. That is, the number of teeth of the output sprocket is “20” in the case shown in FIG. 3 or FIG. 6, and is slightly reduced to “15” in the case shown in FIG. Therefore, the opening / closing devices 4 and 410 in FIGS. 3 and 6 match the reduction ratio of the reduction gear and the rotational performance thereof with respect to the output sprocket having the number of teeth of “20”. It is difficult to control the rotation of the machine 400, 420 simply by replacing the machine 400, 420 with the switch 4,410 of FIG.
