At this time, sliding of the slide lever 80 in the Y1 direction is restricted by a stopper (not shown) provided on the pair of rotating plates 51 and 51.

  Further, when the ring 54 is closed from the state in which the ring 54 is opened, first, the slide lever 80 is pushed down to the base 50 side. As a result, the pair of rotating plates 51, 51 changes from a mountain shape to a flat shape, and the ring 54 is closed.

  Next, the slide lever 80 is pushed down and slid in the Y1 direction. As a result, the slide lever 80 is locked to the stoppers 56 and 56. At this time, the elastic restoring force of the torsion spring 86 acts in the direction of pushing up the slide lever 80 via the pair of rotating plates 51 and 51 and the shaft 71.

  Because of the pushing force, the slide lever 80 is pressed toward the locking pieces 56a and 56a of the stoppers 56 and 56, so that the slide lever 80 is prevented from inadvertently sliding in the Y2 direction, and the ring 54 is inadvertently moved. Can be prevented from being opened.

  As described above, the ring-type binding tool 5 of the present invention can be easily operated because the ring 54 can be opened and closed simply by sliding the slide lever 80 of the operation unit 55 provided at the approximate center of the base 50.

  Further, since the slide lever 80 is formed to be relatively long and narrow, the document or the like bound to the ring 54 can be reliably operated without obstructing the operation.

  Furthermore, since the operation part 55 is provided in the approximate center of the base 50 as described above, it can be manufactured lighter and cheaper than the case where the operation part is provided in the extension part obtained by extending the binding tool as in the prior art. .

  In the above-described embodiment, the coil spring 85 that urges the slide lever 80 of the operation unit 55 in the Y1 direction and the torsion spring 86 that urges the pair of rotating plates 51 and 51 away from the base 50 are provided. Although different types of springs were used, these springs can be integrated.

  FIG. 22 shows a spring 90 in which a coil spring and a torsion spring are integrated. The spring 90 has a coil spring portion 91 and a torsion spring portion 92 extending from both ends thereof.

The coil spring portion 91 is the same as a normal torsion spring. The torsion spring portion 92 is formed in a substantially L-order shape by a long side portion 92a provided at the tip of the coil spring portion 91 and a short side portion 92b extending laterally from the tip of the long side portion 92a. The short sides 92b, 92b of both torsion springs 92, 92 extend in opposite directions.

As shown in FIG. 23, the spring 90 is inserted into the shaft 71 and disposed between the base 50 and the pair of rotating plates 51 and 51. Then, a biasing force in the sliding direction is applied to the slide lever 80 by the coil spring portion 91 of the spring 90, and a biasing force in a direction away from the base 50 is applied to the pair of rotating plates 51, 51 by the torsion spring portions 92, 92. It is done. In FIG. 23, the pair of rotating plates 51, 51 are omitted.

  Thus, by integrating the coil spring and the torsion spring, the number of parts can be reduced. In addition, by integrally molding each component part, the number of parts can be further reduced and the cost can be reduced.
