Thus,The coming off of paper sheet S that bookbinding bar is fixed in bookbinding is prevented from.

In addition, now, the matrix of the matrix 11 of the first bookbinding rod unit 1 and the second bookbinding rod unit 221 become the against each other or approaching state of its medial surface 111,211. One distolateral at pedestal 3The extension part 35 arranging needn't be necessarily with two one end of binding the matrix 11,21 of rod units 1,2 (thoughSo approach) contact. The hook 36 arranging at pedestal 3 is positioned at and relatively approaches at the second bookbinding rod unit 2The position of the hook 26 arranging, the helical spring 4 that is hooked in two hooks 16,36 can not brought into play tension force.

Here, in the present embodiment as shown in figure 14, the helical spring 4 before assembling, it is fixedEnd 41 and twisting action end 42 towards differ 90 ° towards. As it partly cuts open special expression in Figure 15Like that, the switching side hook 16 of the slip side hook 36 of pedestal 3 and the first bookbinding rod unit 1 is in bookbinding positionPut (P1) open and close in direction towards same towards.

That is, as Figure 15 wait as shown in, helical spring 4 in the time being positioned at gutter pos (P1) for not extendingNon-elongation state (Q1), and become by the reaction force that torsion produces of spring and accumulate in bookbindingThe torsion posture (R1) of key element 12 direction of (P2) action to release position.

Conversely, if make pedestal 3 from gutter pos (P1) (P2) slip movement to release position,As shown in Fig. 9, Figure 11, Figure 13, the breach 311 forming at the sidewall 31 of side's side alongThe position of axis direction is consistent with the wrist 14 of the bookbinding rod unit 1 of the same side, in addition in the opposing party's sideThe breach 321 that forms of sidewall 32 the position along axis direction also with the bookbinding rod unit of the same side2 wrist 24 is consistent. Therefore, wrist 14,24 can enter in breach 311,321. Not onlySo, also can by paired breach 311,321 folded positions on the sidewall 31,32 of pedestal 3Enough enter into the space 15 folded by the paired wrist 14,24 that is connected in same axial region 131,23,In 25. As a result of, as shown in Fig. 9, Figure 11, Figure 13, allow two bookbinding rod unit 1,2 phasesRotation is made to bind bar key element 12,22 opens.

Meanwhile, the process being shifted from gutter pos (P1) to release position (P2) at pedestal 3,On the inclined plane 351,352 of the extension part 35 of a distolateral setting of pedestal 3 and at two bookbinding rod units1, inclined plane 116,216 contacts that one end of 2 matrix 11,21 forms, by this matrix 11,21Further push open to direction away from each other. Finally, the extension part 35 of pedestal 3 enters into two bookbinding bars111,211 of the medial surfaces of the matrix 11,21 of parts 1,2. , extension part 35 and matrix 11,One end of 21 is as operating physical force switching mechanism work, by the operating physical force that pedestal 3 is slided to axis directionBe converted to the power that direction that two bookbinding rod units 1,2 are opened to bookbinding bar key element 12,22 is rotated.Generally speaking, by making pedestal 3 from gutter pos (P1) (P2) displacement to release position, blockMake a concession along axis direction from the wrist 14,24 of two bookbinding rod units 1,2, simultaneously extension part 35Two bookbinding rod units 1,2 are pushed open and to make to bind bar open.

Here, in the present embodiment, as shown in figure 16, by the displacement of pedestal 3, at pedestalThe 3 slip side hooks 36 that arrange are away from the switching side hook 16 arranging at the first bookbinding rod unit 1, so generationBe stretched and become elongation state (Q2) and accumulate for the helical spring 4 that is hooked in two hooks 26,36The elasticity bounce of direction shortening, and be released in the anti-of torsional direction that gutter pos (P1) accumulatesActive force, to non-torsion posture (R2) to the direction elastic force-applying that the first bookbinding rod unit 1 is opened., this helical spring 4 by with by a pair of bookbinding rod unit 1,2 to gutter pos (P1) andThe reaction of the relative flexible direction of distortion that the action of the axis direction of release position (P2) producesPower is to a pair of bookbinding rod unit 1,2 elastic force-applyings, and by helical spring 4 self with switching sideTo the reaction force of the relative torsional direction of action to release position (P2) to the first bookbinding rod unit1 elastic force-applying. In addition, at this release position (P2), make pedestal 3 from release position (P2) to dressBooking put (P1) displacement direction elastic acting force, the tensile stress of helical spring 4 works,But the wrist 14,24 of bookbinding rod unit 1,2 is sticked in the breach 311,321 of sidewall 31,32Edge of opening, so pedestal 3 maintains release position (P2).

, as shown in figure 16, helical spring 4 is stretching of extending in the time being positioned at release position (P2)Long status (Q2), and bookbinding key element 12 is got the non-torsion discharging by reversing the reaction force producingPosture (R2).

And, at this release position (P2), the outside on the wrist 14 of the first bookbinding rod unit 1Protuberance 143 is by the elastic force-applying portion application of force of the torsional direction of above-mentioned helical spring 4, until be connected toThe bearing surface 311a of the breach 311 arranging at pedestal 3. In addition, the second bookbinding rod unit 2 passes through certainlyHeavily make the protuberance 243 in the outside on wrist 24 be connected to the butt of the breach 321 arranging at pedestal 3The 321a of portion.

As a result, particularly as shown in Figure 9, (P2) pedestal 3 and a pair of bookbinding bar portion in release positionPart 1,2 is while ground connection on same imaginary plane Z respectively. And, this release position (P2)Stably maintain by the elastic acting force of helical spring 4 and the deadweight of bookbinding rod unit 1,2.

Then, at this release position (P2), if user uses finger to pinch two bookbinding bar key elements12,22 operations of being closed, bind rod unit 1,2 and rotate to direction adjacent to each other, eachWrist 14,24 comes off from the breach 311,321 of the sidewall 31,32 of pedestal 3. Therefore, allow baseSeat 3 resets to gutter pos (P1).

The matrix 11,22 of bookbinding rod unit 1,2 is for long size, so even if will pinch the dress of manyOrder a part for bar and closed, between this position and other positions, probably can produce torsion, bookbinding barParts 1,2 entirety can not rotated to the direction that bookbinding bar cuts out. But, by the pedestal of elastic force-applying3 will be to gutter pos (P1) displacement, what this power will be via the breach of sidewall 31,32 311,321The wrist 14,24 of bookbinding rod unit 1,2 is pressed go back to interior side by edge of opening, so can suppress baseThe torsion of body 11,21, bookbinding rod unit 1,2 unitary rotation and all bookbinding bars cut out simultaneously.

By being made as above such structure, the binder T that present embodiment is related, in axle centerDirection two ends are provided as that one end side shaft that separates prohibition unit performance function places portion 37 and another is distolateralAxle places portion 38 and between them, is provided as the helical spring 4 of elastomeric element, even thus at baseAny end of the axis direction on seat 3 is subject in the situation of intense impact, has also effectively got rid of powerDirective effect from a pair of bookbinding rod unit 1,2 to this pedestal 3 that separate with respect to, cause this pedestal 3The possibility separating in the mode of peeling away gradually with respect to a pair of bookbinding rod unit 1,2. Consequently,Can both stable maintenance under all situations in conventionally using can bind the state of paper sheet S. ,According to present embodiment, realize a pair of bookbinding rod unit 1,2 and pedestal 3 and be difficult for departing from and can maintainThe binder T of stable action. Particularly in the present embodiment, helical spring 4 is not establishedBe placed in axis direction other end edge, thus from gutter pos (P1) to release position (P2) useWhen finger presses operation one end side shaft places portion 37, the size of pedestal 3 deflections can not affect pedestal 3Entirety, has avoided the unnecessary deflection of pedestal 3 effectively.

In addition, in order easily to carry out the assembling of binder T, in the present embodiment, willBe arranged at the substantial middle on the axis direction of pedestal 3 as the helical spring 4 of elastomeric element.

And, as by release position, (P2) makes binder T stable and can easily enterThe structure of the plus-minus operation of row paper sheet S, in the present embodiment, for pedestal 3 is made as to permissionThe action of a pair of bookbinding rod unit 1,2 makes in release position (P2), pedestal 3 and a pair of bookbinding barParts 1,2 are while and the shape that is positioned at the upper ground connection of conplane imaginary plane Z (Fig. 9) respectively,And set the bearing surface 311a, the shape of 321a of breach 311,321.

Particularly, in order to maintain simple structure, make gutter pos (P1) and release position (P2) simultaneouslyBetween level and smooth operation with bookbinding key element 12,22 switching direction on level and smooth action become simultaneouslyVertical, in the present embodiment, as an example, elastomeric element is made as to single helical spring 4, this spiral shellRevolve spring 4 by with by a pair of bookbinding rod unit 1,2 to gutter pos (P1) and release position(P2) reaction force of the relative flexible direction of distortion that the action of axis direction produces is to a pair ofBookbinding rod unit 1,2 elastic force-applyings, and by the first bookbinding bar in a pair of bookbinding rod unit 1,2The elastic reactance of the torsional direction of the helical spring 4 of parts 1 self is to the first bookbinding rod unit 1Elastic force-applying.

And, in the present embodiment helical spring 4 to release position (P2) to the first bookbinding bar portionPart 1 elastic force-applying, makes the first stable release position (P2) that is positioned at of bookbinding rod unit 1.

Particularly in the present embodiment, helical spring 4 in release position (P2) to prolonging direction bulletProperty distortion and the elasticity bounce of torsional direction is further increased, and to release position (P2) executedThe active force adding further increases, thereby promotes opening of level and smooth bookbinding key element 12.

As an example of the separation prohibition unit that can be formed by simple structure, in the present embodiment,It is the two insertion axles that can be captured in the two ends setting of a pair of bookbinding rod unit 1,2 that application separates prohibition unit17,18 axle places the form in hole 37,38.
