2. Description of the Related Art Conventionally, as shown in FIG. 8, two plate-shaped elongated members 5 and 7 each having a plurality of binding ring members which are matched with each other to form a binding ring 3 are made to abut against each other in their longitudinal inner edges. A binder binding device 1 of a type in which a connecting portion is formed, outer peripheral edges of these plate-shaped elongated members are constrained by a sheath-shaped elastic member 4, and the plate-shaped elongated members are moved up and down to open and close the binding ring.
Is widely used. However, in order to open the binding ring 3, the binder binding device 1 firstly has the finger-hanging pieces 9 and 1 integrally formed with the two plate-shaped elongated members 5 and 7.
1 is drawn to each other to open the binding ring 3, and to close the binding ring 3, the binding ring is closed directly with a finger.
It requires two actions.

As yet another method, as shown in FIG. 9, a lever piece 8 instead of the finger hook pieces 9 and 11 is arranged at one end or both ends of an elongated member and attached to the sheath-like elastic member 4. is there. In this case, it is necessary to attach the lever piece to the sheath member 4 when assembling the sheath-like elastic member and to adjust the lever movement so as to generate a proper opening force during the assembly.

[0004]

In the conventional binder binding device 1 shown in FIGS. 8 and 9, in order to open and close the binding ring 3, first, a finger hook integrally formed on the two plate-shaped elongated members 5 and 7 is used. The two operations of pulling the pieces 9 and 11 toward each other to open the binding ring 3 and then closing the binding ring 3 with fingers are troublesome in opening and closing operations and lack smoothness. In addition, loose-leafs or the like that are generally bound may be inadvertently opened due to their own weight, external vibration, or the like during storage before shipment or during transportation. As a countermeasure against this, it is conceivable to increase the elasticity of the sheath-shaped elastic member 4, but if this is done, not only will the force required for opening and closing become relatively large, making it difficult to open and close, but the sound at the time of closing will also be very loud. The problem arises. Also,
Therefore, it is an object of the present invention to provide a binder binding device that can be opened and closed easily and smoothly with one touch.

[0005]
