DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding device for binding documents and the like.

[0002]

2. Description of the Related Art As shown in FIG. 11, a binding tool or a file for binding a document or the like is passed through a binding band b through a document a having a binding hole formed in advance, and a movable piece d of a binding tool c is passed through the binding band b. Is slid to the arrow to bind the documents. In this case, the remaining portion e of the locked binding band b is a movable piece d.
As a result, the file is bent in the same direction as the longitudinal direction of the binding tool c, and each file is pushed down and up and down. For this reason, the surplus e of the binding band b is accommodated in the range between the binding device c and the upper and lower ends of the file, so that the length of the binding band is limited at most to this range.

[0003] Recently, as a file to which more documents are bound, there is a file as shown in FIG. In this file, the front cover r and the back cover s are separated from each other, and the binding tool c for the slide operation described above with reference to FIG. 11 is used. Note that a spine t is connected to the front cover r,
The back cover s is formed in a bag shape, and binding bands u, u are attached to one end thereof. The spine t is formed in a bellows shape alternately folded, and the back cover s
And is housed therein.
In this case, the spine t can be freely pulled out according to the binding amount of the document, and the binding width can be adjusted arbitrarily.

[0004] On the other hand, the band length of the binding band u is set according to the binding width when the binding amount of the document is the maximum. Even if the band length is set unnecessarily long in order to increase the binding amount, if the binding amount is small, the surplus of the folded binding band u is pushed down and up and down of the file with such a binding device c. Because of this, it protrudes out of the file, and on the contrary, its appearance is bad and handling is troublesome. Therefore, the length of the band is naturally limited by the size of the file, and even if an attempt is made to bind more documents, the amount of documents to be bound is limited, and it is difficult to increase the amount of binding.

In order to solve such inconveniences, for example, in Japanese Utility Model Laid-Open Publication No. 2-59989 and Japanese Unexamined Patent Publication No. Hei 7-237383, as shown in FIG. Is bent toward the center (k) of the (bound) document so that the length of the binding band h can be increased.

[0006]

The above-mentioned binding device g comprises two members which are relatively moved in the longitudinal direction by sliding in order to bend the excess j of the locked binding band h toward the center of the document. The movable member m includes an inclined notch p. When the movable member m is slid in the direction of the arrow in the figure, the inclined portion of the notch portion abuts on the binding band h, and by subsequently sliding the movable member m, the binding band h is pressed by the inclined portion. . Therefore, the binding band h is bent (j) along the inclined portion by this pressing, and is pushed down to the document center side k.

However, in such a binding device g, since the direction in which the movable member m slides and the direction in which the binding band h is bent are different, an excessive force acts on the binding band h, causing the binding band h to be damaged. In addition, the binding band h does not bend smoothly, so that it is difficult to bind the binding band h smoothly. Further, the pressing force acting on the binding band h is
This is a component of the force required to slide the binding device (movable member m), and as a result, an excessive slide force is required.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-described problems, and has as its object to bind as many binding members as possible, such as documents, and to bind a binding band without force. Can be bent smoothly without
Moreover, it is an object of the present invention to provide a binding device that does not require excessive force and has good operability.

According to this solution, the binding movable body, which is connected and supported by the binding body, is substantially parallel to the binding body and is rotatably provided. The direction in which the binding band is rotated and brought into contact with the binding band inserted through the insertion hole and bent can be arbitrarily set. This direction is a direction in which the length of the binding band can be set as long as possible when the binding band is bent, that is, a bending direction of the binding band in which the binding amount of a member to be bound such as a document can be increased as much as possible. There is, and it is a direction which bends a binding band easily. Due to the turning motion of the binding tool movable body,
The binding band can be easily abutted in such a direction. On the other hand, the binding tool movable body and the binding tool body face each other substantially in parallel and are provided at a predetermined interval.
Since the binding band inserted through the insertion hole is bent at a substantially right angle in the rotation direction by the rotation of the binding movable body, the binding band inserted through the insertion hole is rotated by the binding movable body. It is easily bent in this operation direction by the operation, and is engaged and held between the binding device main body and the binding device movable body. Therefore, the binding band is bent smoothly and smoothly to a predetermined portion, such as the center of the document, which can be set as long as possible.
The binding amount can be increased as much as possible, and the bending allows the binding tool and the binding band to be securely locked to bind a document or the like. Furthermore, since the turning direction of the binding member movable body and the bending direction of the binding band by this operation are the same direction, there is no loss due to the component force as in the prior art.
The minimum necessary force is sufficient. In addition, the binding tool movable body can reduce the necessary force as much as possible by setting the turning radius from the support portion to a predetermined value so that the lever principle can be used.

According to a second aspect of the present invention, there is provided a method as set forth in the first aspect, wherein the binding member main body and the binding member movable body are provided at a portion opposed to the support portion with the insertion hole interposed therebetween.
