And then in this example, between described base 1 and described stapling operation body 3, further possess make described stapling operation body 3 with described base 1 relative to the use location of the state of configuration and can fill rotate between the retreating position of state of staple keep out of the way the T of mechanism.At this, in Figure 11, represented to make described stapling operation body 3 to turn to the figure of the state suitable of the state of retreating position with Fig. 4.Specifically, when under the state of having removed described locking mechanism R with described stapling operation body 3 upward during pull-up, described engaging screw 411 and described holding section 42b are keeping the state that cooperates, described guiding part 42 rotates upward.That is, described stapling operation body 3 can rotate synchronously with guiding part 42.

So in this example, described pressing component 5 is arranged on the pressing component installation portion 3a of described stapling operation body 3, have this stapling operation body 3 accepted under the situation of operating physical force will with described staple kink 1x over against the function released to this staple kink 1x of staple.

Specifically, this pressing component 5, shown in Figure 4 as described, have the portion of being mounted 51, hammer into portion 52 and flat spring portion 53, wherein be mounted portion 51 and have to make and the screw that screw passes is installed is passed the hole; Hammering into portion 52 extends to described this staple kink 1x from the end that this is mounted described this staple kink 1x side of portion 51, simultaneously described stapling operation body 3 is being applied under the situation of operating physical force, the end and the staple of described this staple kink 1x side touch; Flat spring portion 53 has from the described the other end of portion 51 that is mounted to the such extension obliquely of direction decline away from described this staple kink 1x.Further be described in detail, the pressing component installation portion 3a that this pressing component 5 is screwed on described stapling operation body 3 by the installation screw that will pass the described screw that is mounted portion 51 and pass the hole goes up and is installed on the described stapling operation body 3.In addition, described flat spring portion 53 touches with described magazine 21 under the situation that has applied operating physical force and this pressing component 5 is loaded upward.And this pressing component 5 is connected with push rod 221 that staple is sent portion 22 to via being installed in that staple on the spring installation portion 5x pushes spring S 3 as mentioned above.

When with the stapler S bookbinding paper class that constitutes as previously discussed, described stapling operation body 3 is accepted operating physical force.The following narration that acts on for each one at this moment.

At first, the operating physical force of stapling operation body 3 acceptance is delivered to described pressing component 5.Stage in the early stage, in order to depress described magazine 21 when working, described pressing component 5 is near described magazines 21 at described operating physical force.Then, when described magazine 21 touched with the paper class, described pressing component 5 touched with this magazine 21.When further when stapling operation body 3 applies operating physical force, preceding operating physical force is directly passed to over against the staple of staple kink 1x from described pressing component 5, and staple is released to described staple kink 1x by the portion that hammers into 52 of described pressing component 5.And the staple that is pushed out is by being bound the paper class by described staple kink 1x bending.Bound after the paper class, the flat spring portion 53 of described pressing component 5, agreed spring S1 and stapling operation body support spring S2 strain without prior consultation and turn back to state before the bookbinding paper class.

In addition, for the following explanation that operates in of in such stapler, filling staple.

At first, latch-release operating body 62 being slided moves.So lock pawl 61 is disengaged with the cooperation that engages pawl 421 of described guiding part 42.When in this state stapling operation body 3 being rotated upward, the operating physical force that makes it to rotate upward is delivered to guiding part 42 via described engaging screw 411 and holding section 42b, stapling operation body 3 and guiding part 42 rotate to retreating position, and magazine 21 is opened with respect to the space of top.Then, in magazine, replenished after the staple, when making stapling operation body 3 when base 1 rotates, stapling operation body 3 and guiding part 42 rotate to the use location, when stapling operation body 3 and guiding part 42 arrival use locations, described Lock Part 6 strains make lock pawl 61 cooperate with the pawl 421 that engages of described guiding part 42 once more.

As previously discussed, because the stapler S of this example, pressing component 5 is located on the stapling operation body 3, therefore can make the simply constructed while, because the operating physical force that stapling operation body 3 is pushed point-blank to base 1 is directly passed to pressing component 5, therefore the action of pushing the stapling operation body to base can be directly converted to the action of bookbinding paper class, can bind the paper class with less action.

In addition, because between described base 1 and described stapling operation body 3, further possess make described stapling operation body 3 with described base relative to the use location of the state of configuration and can fill rotate between the retreating position of state of staple keep out of the way the T of mechanism, therefore, as long as just can carry out the filling of staple, therefore can more easily carry out the filling of staple owing to make described stapling operation body 3 turn to retreating position.

And then, because so that described stapling operation body 3 forms the described T of mechanism that keeps out of the way with the mode that described guiding part 42 synchronously rotates, therefore, this stapling operation body 3 and guiding part 42 are turned under the state of described retreating position, described magazine 21 is exposed with respect to top and space, side, thereby, can more easily carry out the filling of staple.

By described guiding part 42 is hubbed on the described base 1 via guiding part installation shaft X1, can more easily realize said structure.

Because the magazine 21 of described staple feed mechanism 2 is hubbed on the described base 1 via the locational magazine installation shaft X2 that is located at apart from described guiding part installation shaft X1 deflection below, therefore in easier while of the installation to base 1 of this magazine 21, because described guiding part installation shaft X1 is positioned at the position by the top than magazine installation shaft X2 at least, therefore described retreating position can be set in the position of more leaning on the top, can more easily carry out the filling of staple.

And then, owing to further possess locking mechanism R, and this locking mechanism R have be located at described guiding part 42 on engage that pawl 421 cooperates and described guiding part 42 be fixed on the lock pawl 61 on the described use location and move the cooperation that the cooperates releasing operating portion 62 of removing described engaging pawl 421 and lock pawl 61 by sliding, therefore can guiding part 42 as described above be fixed on the described use location with simple structure, can also remove fixing and make it to rotate with shirtsleeve operation simultaneously to retreating position.

And, owing to form described guide pins 41 cylindric, also on described guiding part 42, formed the mating holes 42a that can cooperate simultaneously with described guide pins 41, therefore when forming columned guide pins 41, need not form pattern draft, can fine set and described mating holes 42a between the gap, can carry out the slip between described guide pins 41 and the described guiding part 42 smoothly.

Moreover, the invention is not restricted to above-described example.

For example, the shape of operating portion, except above-mentioned, also can constitute various, for example cube, cuboid, hemispherical or personage in simulation caricature, cartoon, the computer game and other well-known roles' shape etc.

In addition, the shape of guidance part also can be that guide pins and guiding part are provided with 4 pairs or more than it or only be provided with 2 pairs, in addition respectively, can also use the structure that constitutes by the parts beyond the combination of guide pins that can cooperatively interact and guiding part, for example use the structure of X linkage etc.

In addition, in the scope that does not undermine aim of the present invention, can carry out various changes.
