As shown in Fig. 8, Figure 10, Figure 12 and Figure 15 etc., when pedestal 3 is located at gutter pos (P1), it is formed in a side side The notch 311 of side wall 31 is staggered on axis direction relative to the wrist 14 of ipsilateral bookbinding rod unit 1, is formed in another party side The notch 321 of side wall 32 be staggered on axis direction also relative to the wrist 24 of ipsilateral bookbinding rod unit 2.Therefore, as being somebody's turn to do Shown in figure, even if rotate two bookbinding rod units 1,2 to that will bind the direction that bar opens, wrist 14,24 also collides pedestal 3 Side wall 31,32 end margin, be able to rotate it not.If in other words, not being cut off on the side wall 31,32 of pedestal 3 End margin become block, forbid binding bar open.The falling off for paper sheet S that bookbinding bar is fixed in bookbinding as a result, is prevented from.

In addition, at this point, the matrix 21 of the matrix 11 of the first bookbinding rod unit 1 and the second bookbinding rod unit 2 becomes its inside The state against each other or close of face 111,211.It is not bound with two necessarily in the extension part 35 that the one end of pedestal 3 is arranged One end (although close) contact of the matrix 11,21 of rod unit 1,2.It is located in the hook 36 that pedestal 3 is arranged relatively second The position for the hook 26 that rod unit 2 is arranged is bound, the helical spring 4 for being hooked in two hooks 16,36 will not play tension.

Herein, in the present embodiment as shown in figure 14, the helical spring 4 before assembling, fixing end 41 and torsion are dynamic Make end 42 towards 90 ° of difference of direction.As particularly shown in its semi-cutaway 15, the sliding side hook 36 and first of pedestal 3 The opening and closing side hook 16 of bookbinding rod unit 1 is in gutter pos (P1) in opening and closing side upwardly toward same direction.

That is, as shown in Figure 15 etc., non-elongate state that helical spring 4 is not extended when being located at gutter pos (P1) (Q1), and become the accumulation of the reaction force from produced by the torsion of spring in the side that bookbinding element 12 is acted to release position (P2) To torsion posture (R1).

In turn, if pedestal 3 is made to slide movement from gutter pos (P1) to release position (P2), such as Fig. 9, Figure 11, Shown in Figure 13, a side side side wall 31 formed notch 311 along the position of axis direction and the bookbinding bar portion of the same side The wrist 14 of part 1 is consistent, and the position along axis direction for the notch 321 that in addition side wall 32 in another party side is formed is also and together The wrist 24 of the bookbinding rod unit 2 of side is consistent.Therefore, wrist 14,24 is able to enter in notch 311,321.Moreover, The position as folded by pairs of notch 311,321 on the side wall 31,32 of pedestal 3 is also able to enter by being connected to same axle portion 131, in gap 15,25 folded by 23 pairs of wrist 14,24.As a result, allowing two dresses as shown in Fig. 9, Figure 11, Figure 13 It orders the relative rotation of rod unit 1,2 and makes to bind the opening of bar element 12,22.

Meanwhile during pedestal 3 is shifted from gutter pos (P1) to release position (P2), in the one end of pedestal 3 The inclined surface that the inclined surface 351,352 of the extension part 35 of setting and one end of the matrix 11,21 in two bookbinding rod units 1,2 are formed 116,216 contact, which is further pushed open to direction away from each other.Finally, the extension part 35 of pedestal 3 enters To between the medial surface 111,211 of the matrix 11,21 of two bookbinding rod units 1,2.That is, one end of extension part 35 and matrix 11,21 is made For operating force switching mechanism work, the operating force for sliding pedestal 3 to axis direction is converted to make two bookbinding rod units 1,2 to Bind the power for the direction rotation that bar element 12,22 is opened.To sum up, by making pedestal 3 from gutter pos (P1) to open stance (P2) displacement is set, block is made a concession from the wrist 14,24 of two bookbinding rod units 1,2 along axis direction, while extension part 35 is by two Bookbinding rod unit 1,2 is pushed open and keeps bookbinding bar open.

Herein, in the present embodiment, as shown in figure 16, by the displacement of pedestal 3, in the sliding side that pedestal 3 is arranged Hook 36 is far from the opening and closing side hook 16 being arranged in the first bookbinding rod unit 1, so instead of the helical spring 4 for being hooked in two hooks 26,36 It is stretched and becomes elongation state (Q2) and accumulate the elastic rebound power in the direction of shortening, and discharge and accumulated at gutter pos (P1) Torsional direction reaction force, to non-twisted posture (R2) to make the first bookbinding rod unit 1 open direction it is elastic force-applying. That is, the helical spring 4 by with from a pair of of bookbinding rod unit 1,2 to the axle center side of gutter pos (P1) and release position (P2) To movement caused by deform the reaction force of opposite telescopic direction elastic force-applying to a pair of bookbinding rod unit 1,2, and By the reaction force of helical spring 4 itself torsional direction opposite with the movement in opening and closing direction to release position (P2) to the One bookbinding rod unit 1 is elastic force-applying.In addition, making pedestal 3 from release position (P2) to gutter pos in the release position (P2) (P1) elastic acting force in direction, the i.e. tensile stress of helical spring 4 shifted works, but binds the wrist of rod unit 1,2 14,24 be sticked in side wall 31,32 notch 311,321 open edge, so pedestal 3 maintains release position (P2).

That is, as shown in figure 16, helical spring 4 is the elongation state (Q2) of elongation when being located at release position (P2), and Bookbinding element 12 takes the non-twisted posture (R2) of release reaction force caused by reversing.

Moreover, the protruding portion 143 in the outside on the wrist 14 of the first bookbinding rod unit 1 is by upper in the release position (P2) The elastic force-applying portion force for stating the torsional direction of helical spring 4, until being connected to the bearing surface for the notch 311 being arranged in pedestal 3 311a.It is arranged in addition, the second bookbinding rod unit 2 is connected to the protruding portion 243 in the outside on wrist 24 by self weight in pedestal 3 Notch 321 abutting part 321a.

As a result, especially as shown in figure 9, existing simultaneously respectively in release position (P2) pedestal 3 and a pair of of bookbinding rod unit 1,2 It is grounded on same imaginary plane Z.Moreover, elastic acting force and bookbinding bar portion that the release position (P2) passes through helical spring 4 The self weight of part 1,2 steadily maintains.

Then, in the release position (P2), if user carries out pinching two bookbinding bar elements 12,22 with finger and be turned off Operation, then bind rod unit 1,2 and rotated to direction adjacent to each other, each wrist 14,24 is lacked from the side wall 31,32 of pedestal 3 Mouth 311,321 falls off.Therefore, pedestal 3 is allowed to reset to gutter pos (P1).

The matrix 11,22 for binding rod unit 1,2 is long size, so even if a part that pinch more bookbinding bars will It is closed, and torsion can be probably generated between the position and other positions, bookbinding rod unit 1,2 will be whole to close to that will bind bar Direction rotation.However, to be shifted to gutter pos (P1) by elastic force-applying pedestal 3, which will lacking via side wall 31,32 The wrist 14,24 for binding rod unit 1,2 is pressed go back to interior side by the open edge of mouth 311,321, so being able to suppress matrix 11,21 Torsion, bookbinding rod unit 1,2 unitary rotations and all bookbinding bars are closed simultaneously.

By being set as above such structure, binder T involved in present embodiment is arranged at axis direction both ends It is arranged as between one end side axle retracting portion 37 for functioning of separation prohibition unit and other end side axle retracting portion 38 and they As the helical spring 4 of elastomeric element, even if thus feelings of any end of the axis direction on pedestal 3 by intense impact Under condition, also effectively eliminates power and acted on to the pedestal 3 direction isolated relative to a pair of of bookbinding rod unit 1,2, lead to the base A possibility that seat 3 is separated in a manner of gradually peeling away relative to a pair of bookbinding rod unit 1,2.As a result, usually used In all situations under can stablize and maintain that the state of paper sheet S can be bound.That is, according to the present embodiment, realizing a pair of Bookbinding rod unit 1,2 and pedestal 3 are not easy to deviate and be able to maintain that the binder T of stable movement.Especially in this embodiment party In formula, helical spring 4 another end margin of axis direction is not set to, so from gutter pos (P1) to release position (P2) press...with one's finger press operation one end axis retracting portion 37 when, it is whole that the size that pedestal 3 is bent will not influence pedestal 3, effectively Avoid the unnecessary flexure of pedestal 3.

In addition, in order to be easy to carry out the assembling of binder T in the present embodiment, elastomeric element will be used as Helical spring 4 be set to the substantial middle on the axis direction of pedestal 3.

Moreover, as by making to can easily be done adding for paper sheet S and binder T is stable at release position (P2) Subtract the structure of operation, in the present embodiment, in order to pedestal 3 is set as allowing a pair of of bookbinding rod unit 1,2 movement so that Release position (P2), pedestal 3 and a pair of of bookbinding rod unit 1,2 respectively simultaneously with the imaginary plane Z (Fig. 9) that is generally aligned in the same plane The shape of upper ground connection, and set the shape of bearing surface 311a, 321a of notch 311,321.

Especially for maintaining simple structure, at the same make between gutter pos (P1) and release position (P2) smoothly It operates and is set up simultaneously with the smooth movement on the opening and closing direction of bookbinding element 12,22, in the present embodiment, as an example will Elastomeric element is set as single helical spring 4, the helical spring 4 by with from a pair of of bookbinding rod unit 1,2 to gutter pos (P1) and the reaction force of the opposite telescopic direction of deformation caused by the movement of the axis direction of release position (P2) is to a pair Bookbinding rod unit 1,2 is elastic force-applying, and certainly by a pair of helical spring 4 for binding the first bookbinding rod unit 1 in rod unit 1,2 The elastic reactance of the torsional direction of body is elastic force-applying to the first bookbinding rod unit 1.

Moreover, helical spring 4 is elastic force-applying to the first bookbinding rod unit 1 to release position (P2) in the present embodiment, Stablize the first bookbinding rod unit 1 and is located at release position (P2).

Especially in the present embodiment, helical spring 4 makes to turn round at release position (P2) to prolonging direction flexible deformation The elastic rebound power for turning direction further increases, and further increases the active force applied to release position (P2), to promote Into the opening of smooth bookbinding element 12.

As an example for the separation prohibition unit that can be made of simple structure, in the present embodiment, prohibit using separation Stop is can be placed in the shape in the axis retracting hole 37,38 of two insertion axis 17,18 of both ends setting of a pair of of bookbinding rod unit 1,2 State.
