On the other hand, under the state of not boring a hole, inclined plane 111 is positioned at central portion, because its left and right sides is formed with the face of holding up 110, so, even entering, inserts in the space S on finger, finger tips etc. also can only be run into the face of holding up 110, so long as not applying power upwards consciously, just can not cause guiding parts 26 rotation displacements.Therefore, can reduce significantly because finger enters caused danger in the insertion space S because of carelessness.

In perforation procedure to paper P, as shown in Figure 2, hold the handle portion 56 of the action bars 18 that is in initial position, rotating operation is carried out just in the position when perforation.Action bars 18, arrive by above-mentioned vertical line L 1 from initial position become with the inclination of the roughly the same angle of θ 1 towards straight line L3 near scope in, above-mentioned the 1st coupling position A1 forwards moves, the slippage of relative with the amount of spin of action bars 18 thus slide unit 20 is less relatively, but in the time of near passing through straight line L3, the 1st coupling position A1 is positioned at the position near the vertical line that passes through the 2nd coupling position A2, therefore, the slippage of slide unit 20 relatively becomes big.

Slide unit 20 descends, and pushing of pressing component 27 facial 130 contacts with the paper P of upper, just can apply pressing force to paper P.In this state, further during rotating operation bar 18, under pressing component 27 was subjected to descending the state of restriction, slide unit 20 descended relatively with respect to this pressing component 27, by this decline, bore cutter 24 can be squeezed in the paper P, bores a hole.

Like this, bore cutter 24 is accepted face with the perforation not shown in the figures of supporting surface 11 and is collided, and becomes the state that bore cutter 24 connects all paper P thus.At this moment action bars 18 is in as shown in Figure 2 from the lodging position of horizontal line L 2 rotational angle θ 2.

Then, in the opposite direction during rotating operation bar 18,, can fully apply paper feeding P owing to push facial 130 pressing force, so the below paper P of bore cutter 24 from plurality of sheets of paper P extracts and rise with slide unit 20 in the starting stage.Yet, along with the rising of slide unit 20, push facial 130 pressing force reduction, so bore cutter 24 is difficult to extract, might cause the tendency that paper P separates up and down, top paper P rises with bore cutter 24 from the paper P of upper side.This is the existence owing to the top paper P that lifts attached to bore cutter 24 most advanced and sophisticated sides, makes to push facial 130 and overcome the power of helical spring 137 and be positioned at than bore cutter 24 is most advanced and sophisticated and cause by the position of top more.

Thereby dock with stage portion 14A, the 15A of the lower end side that is located at support member 14,15 in the both end sides of pushing facial 130 by further rotating of action bars 18, perhaps above-mentioned crooked facial 143 dock with rotating shaft 16 and when arriving the rising limit, the rotation of the action bars 18 after this, because bore cutter 24 is relative together with slide unit 20 to be pushed facial 130 and rises towards the top, so, at this moment the top paper P attached to bore cutter 24 most advanced and sophisticated sides comes off from bore cutter 24 most advanced and sophisticated sides forcibly, thus, bore cutter 24 is extracted from all paper P.

Like this, after pushing the facial 130 arrival rising limit, in order to carry out extracting of bore cutter 24, on the contact-making surface of pushing face 130 and stage portion 14A, 15A, be applied with certain load, still, in the present embodiment, pushing facial 130 docks with stage portion 14A, 15A, be arranged on crooked facial 143 of pressing component 27 tops simultaneously and contact and dock with the Lower Half outer peripheral face of rotating shaft 16, therefore, a plurality of positions about above-mentioned load is dispersed in.Thus, can avoid the distortion of pressing component 27 or the damage of stage portion 14A, 15A etc.

In addition, carry out at the inserting side ora terminalis P1 to paper P under the situation of four position perforation, as shown in figure 11, aligning parts 30 is extracted out from pedestal 12, it is just passable that position limiting part 31 is holded up.In this state, making under another side of paper P P2 and the state that position limiting part 31 docks, the inserting side ora terminalis P1 of paper P can be inserted into and insert in the space S, as described above, this action bars 18 of rotating operation gets final product like this.At this moment, be positioned at the supporting surface of the aligning parts 30 on right side, support the zone of giving prominence to, prevent that this zone is sagging, avoid the dislocation of the sagging paper position that causes effectively from the supporting surface 11 of pedestal 12 as expansion.

Like this, after being bored a hole in two positions of inserting side ora terminalis P1,, use rheme and put limiting part 31 and carry out position restriction and perforation the upset of the top and bottom of a repeated paper P, can amount to four enterprising eleven punch 11s in position with respect to the center of inserting side ora terminalis P1 thus.In other words, carry out once operation in the centre, and carry out the double piercing operation, can carry out the perforation of bore cutter 24 number twices thus as condition with the top and bottom upset of paper P.

Yet,, with the compressive state obstruction a lot of smear metal Pa (with reference to Fig. 8) are arranged in the inside of bore cutter 24 because of boring a hole.Under the state on the body piece 60 that knife rest 23 is installed in slide unit 20, because the inside of bore cutter 24 is communicated with path 80 straight lines, so these smear metals Pa connects to bar-shapedly in the mode between these joint portions of crossing over and exists.Therefore, when the replacing of carrying out bore cutter 24, maintenance, inspection etc., even knife rest 23 the place ahead from body piece 60 is disassembled, because compression and connect to the existence of bar-shaped smear metal Pa makes these operations very difficult.

Given this, by pushing the front as the operating side of above-mentioned backstopping assembly 106 downwards, releasing crook 106A engages with claw 84, inclined plane 100B by means of a following side that is arranged on projecting strip part 100, lower unit 90 is tilted, knife rest 23 integral body are tilted in the mode that its top becomes front one side, and fractureing connects to bar-shaped smear metal Pa.Therefore, under this inclination attitude, as shown in figure 10, can by the processing ease forwards extracted out unload lower slide 23, can extract bore cutter 24 on the top of the support tube 98 of lower unit 90, change.

Therefore, according to such embodiment, the rotational angle of action bars 18 can be set for less than type in the past, can alleviate operating physical force, carries out the perforation on hundreds of the paper, in addition, can also forbid that finger enters to insert in the space S, has improved security.

In addition, can prevent when paper P extracts bore cutter 24 pressing component 27 and the damage at the position of engaging with it.

Have again, can eliminate the difficult main cause of knife rest 23 dismountings that smear metal Pa causes, can simply and carry out the loading and unloading of knife rest 24 apace, simultaneously, even knife rest 23 may tilt, utilize backstopping assembly 106, the installation site that also can remain knife rest 23 is a certain position.

Have again, when carrying out the perforation of bore cutter 24 number twices, utilize aligning parts 30 can enlarge the supporting surface of paper P, so, on one side can overcome the shortcoming that staggers mutually in the position of paper P face, Yi Bian bore a hole in the precalculated position.
