Thereby substrate 1 further is provided with positioning element 21 vertically the sliding at substrate 1 that is used for paper bundle 100.
Shown in Fig. 3 A and 3B, positioning element 21 is formed by synthetic resin, and have first guiding surface 22 of the end surfaces that is used for guiding paper bundle 100, be used for second guiding surface 24 in the bight of guiding paper bundle 100 in opening 23 both sides, this opening 23 is formed centrally and is used to prevent the slip prevention part 25 that paper skids in first guiding surface 22, extend its both sides from first guiding surface 22.And positioning element 21 is provided with slide protrusion 26 at the place, both sides of its underpart, and slide protrusion 26 engages with the guide rail groove (not shown), and this guide rail groove forms in vertically along two inside surface of side wall of substrate 1.
As shown in Figure 1, aforementioned first guiding surface 22 is provided with perpendicular to bookbinding platform 2.The opening 23 that forms in the center of first guiding surface 22 is used for preventing during stapling operation nail box 6 is exerted an influence.Second guiding surface 24 about substrate 1 along its longitudinally center line form with 45 ° angle.Second guiding surface 24 also is provided with perpendicular to bookbinding platform 2.
The standing portion 27 that slip prevention part 25 projects upwards in the both sides from first guiding surface 22 forms, thereby in holding fix, the upper end of slip prevention part 25 is positioned at the higher position of lower surface than nail box 6, thereby have enough height, when preventing on paper bundle 100 being placed on bookbinding platform 2, paper bundle 100 skids below the box 6 at nail between first guiding surface 22 and nail box 6.
A plurality of mark lines 29 form diagonally in the both sides that clench groove 17 of bookbinding platform 2.Corresponding mark line 29 forms about the center line of substrate 1 angle with 45 °.And, form guide line 28 in the both sides of substrate 1.
According to said structure, shown in Fig. 4 A and 4B, positioning element 21 slides aligning with suitable guide line 28, and the end surfaces of paper bundle 100 is resisted against on first guiding surface 22 to bind, and is fixed at this end surfaces and the distance that clenches between the groove 17 thus.Then, by along first guiding surface, 22 slip paper bundles 100, can always bind this paper bundle 100 at the end surfaces same distance place of distance paper bundle 100.Therefore, obtained good surface appearance.And, when page rotates, rotate the extension alignment of page or leaf, and page can not scatter up and down along initial page.Therefore be easy to see page.
In the situation in the bight of bound paper bundle 100 only, the bight of paper bundle 100 is inserted in the opening 23 of positioning element 21.At this moment, the end surfaces that is positioned at the place, both sides, bight of paper bundle 100 is guided by second guiding surface 24, can locate paper bundle 100 reliably thus.And, aim at the mark line 29 of binding platform 2 by the end surfaces that will be positioned at place, both sides, bight, the direction of the end surfaces that staple can be located about these both sides at the gutter pos place is provided with angle at 45, and can obtain good surface appearance.
And, by making positioning element from clenching groove and retreat or, can freely selecting to bind the position of part near clenching groove.
Because second guiding surface 24 forms perpendicular to bookbinding platform 2, when paper bundle 100 during against second guiding surface 24, paper bundle 100 is not bent upwards or is shifted.
And, because the width of opening 23 is a bit larger tham the length that clenches groove 17, there is not gutter pos elongation portion shortcoming too far away.
And, because slip prevention part 25 in the time of on paper bundle 100 being placed on bookbinding platform 2, can prevent effectively that paper from skidding below nail box 6 between positioning element 21 and nail box 6.
And, the number of the paper 100 of being bound when need hour, by paper bundle 100 being pressed against first guiding surface 22, positioning element 21 does not move.Yet when the number of the paper bundle 100 of being bound at need was big, positioning element 21 moved sometimes, because the impact that they are pressed against first guiding surface 22 becomes bigger.Therefore, consider the resistance to sliding that increases positioning element 21, perhaps when functional unit stops, use screw etc. increases the friction between the surface of positioning element 21 and substrate 1 thus.In above-mentioned stapler, adopted a kind of mechanism that can stop positioning element 21 and keep this state in definite position reliably.
More specifically, shown in Fig. 5 A and 5B, substrate 1 is provided with the small calibration groove 30 that is used to locate paper bundle 100, and calibration groove 30 forms clenching groove 17 back along the longitudinal direction of substrate 1.On the other hand, thereby form the fastener 31 that can engage aforementioned calibration groove 30 side-prominent towards the rear surface (side relative) in the bottom of positioning element 21, shown in Fig. 3 A and 3B with clenching groove 17.Both sides at the far-end of fastener 31 form ledge 32.Fastener 31 is integrally formed into positioning element 21, thereby can rotate up and down by elastic bending.
Corresponding to fastener 31, form in the bottom of arm 33 to the U-shaped groove 34 of under shed, this part is extended (seeing Fig. 5 A) from the sidewall of the inner surface of the opening 23 that constitutes positioning element 21.The upper surface of U-shaped groove 34 and fastener 31 forms support unit.These support units grasp axial region 36 in the central authorities of axle 42, rotatably keep action bars 35 with rotational engagement part 31 up and down thus.
The axial region 36 that engages with aforementioned support unit forms (seeing Fig. 5 A) in the central authorities of action bars 35, and the stop member 37 of cubic shape is integrally formed in the central position relative with the bottom of nail box 6.In the both sides of axial region 36, form Z-shaped alar part 41, each alar part 41 has wall portion 38, spring-loaded part 39 and tongue 40, and they bend each other in the right angle, thereby outwards outstanding diagonally.The axle 42 that spring 45 (biasing member) is installed forms at an end place of aforementioned axial region 36.Spring 45 engages with the prodger 43 of spring-loaded part 39 at one end place, and in the edge join of other end place and rank shape part 46, this other end is arranged on recess 44 places in the base portion that is formed at tongue 40.According to this structure, action bars 35 rotates up and down by rotation, simultaneously the direction bias voltage that is rotated along quilt by spring 45.Thereby when with rotary manipulation bar 35 antagonistic springs 45 it upwards being rotated with the standing portion 27 of finger grip positioning element 21 and tongue 40, tongue 40 engages to stop the rotation with the rear surface of standing portion 27, and aforementioned thus stop member 37 is placed in the upright state.Stop member 37 so forms, and makes in upright state its upper end be in than clenching the higher position of groove 17,
In addition, positioning element 21 is provided with from rearwardly projecting rank, the lower end of first guiding surface 22 shape part 46.Rank shape part 46 so forms, thereby when alar part 41 upwards rotated, the spring-loaded part 39 of alar part 41 can form with rank shape part 46 and contact, shown in Fig. 3 B.
And the push part 47 with tubular curved surface forms at the base portion of the stop member 37 of action bars 35.Both sides in push part 47 form engage hook 38.
Aforementioned push part 47 has the function of the upper surface of pushing fastener 31 when thereby action bars 35 rotations rotate, thereby rotates fastener 31.Simultaneously, engage hook 48 moves away the ledge 32 of fastener 31 both sides.On the other hand, thereby when action bars 35 rotations were upwards rotated, the engage hook 48 of action bars 35 engaged the downside of the ledge 32 of fastener 31, and rotational engagement part 31 thus makes progress.Simultaneously, push part 47 moves away the upper surface of fastener 31.
The reason of utilizing the engage hook 48 of action bars 35 to force fastener 31 upwards to rotate is in order to prevent the permanent deformation of fastener 31, and this utilizes himself elasticity and has hindered the abundant operation of fastener 31.
According to said structure, thereby when action bars 35 rotations rotated, shown in Fig. 5 A, fastener 31 rotated to engage calibration groove 30.When thereby action bars 35 rotations were upwards rotated, shown in Fig. 5 B, thereby fastener 31 upwards rotated disengaging calibration groove 30.Accordingly, by rotating operation bar 35 upwards, the positioning element 21 that can slide, and by downward pressing operation bar 35 to desired position, can stop positioning element 21 and hold it in the same position.Therefore, though the heavy a large amount of paper in being in stacked state against first guiding surface 22 of positioning element 21 when determining gutter pos, positioning element 21 does not move, and can always impact staple in the positions of being determined by positioning element 21.
When staple stopped up in the release part 12 of nail box 6 therein, action bars 35 upwards rotated so that stop member 37 is upright, shown in Fig. 3 B and Fig. 5 B.Because stop member 37 is in than the lower position of nail box 6, the lower surface of nail box 6 can not move to the position of position when being lower than it against stop member 37.Nail box 6 is held to leave and clenches groove 17.In this state, press lower handle, and the staple 11 that stops up is released to discharge from releasing part by drive plate 14 in releasing part.In this way, can easily remove staple, i.e. during their obstructions of box lunch.
Because aforementioned power multiplying mechanism, though even above-mentioned stapler is configured to utilize little power also can realize big bookbinding power, this stapler can be a conventional system, wherein can be by direct pushing inside handle (handle) operating this stapler, and do not use outer handle.
Though be described, for those of ordinary skills clearly, can make various changes and modification with not deviating from the present invention in conjunction with embodiments of the invention.Therefore be desirably in and contain this change and the modification that all fall into true spirit of the present invention and scope in the claims.
