  Further, although not shown, the six rotating drums 46 are returned to the initial state in which the number of the outer peripheral surface 46A becomes "000000" by the reset mechanism.

  Next, the operation of the shutter curtain movement number counting unit 40 will be described with reference to FIGS.

  As described above, in FIG. 14, the shutter curtain 1 which has reached the fully open position starts closing movement, and the counting device main body 21 attached to the seat plate 1B of the shutter curtain 1 in the closing movement is permanent magnet 22. Is a diagram showing a state immediately before passing through the In FIG. 14 and FIGS. 15 and 16 used in the following description, the shutter curtain movement number counting unit 40, the permanent magnet 22, and the permanent magnet attachment member 29 for attaching the permanent magnet 22 to the lint member 12A. Indications of members, devices and the like other than those are omitted.

  As shown in FIG. 2, the shutter curtain 1 reaches the fully open position and stops, and in the state where no external force is applied, the swinging member 42 of the shutter curtain movement number counting unit 40 is directed downward as shown in FIG. It is in a rocking posture. The downward swinging posture of the swinging member 42 starts the closing movement of the shutter curtain 1 which has reached the fully open position, and the counting device attached to the seat plate 1B of the shutter curtain 1 in the closing movement. The body 21 is maintained until just before passing the permanent magnet 22.

  FIG. 15 is a view similar to FIG. 14 showing that the shutter curtain 1 is further closed and moved, and the counting device body 21 shown in FIG. 14 is passing in front of the permanent magnet 22.

  As shown in FIG. 15, the counting device main body 21 approaches the permanent magnet 22 from above and passes in front of the permanent magnet 22 so that the shutter curtain movement number counting portion 40 of the counting device main body 21.
