As a result, each staple storage section 76 of the staple storage body 60
One of the staple groups 79 with leg lengths of 6 mm, 10 mm, and 15 mm, that is, the staple group 79 with a size selected according to the thickness of the stacked sheets A.
A needle storage section 76 having a needle storage section 76 is disposed directly below the actuating body 14, and the needle at the leading end of the needle group 79 is placed on the needle receiving plate 3 immediately below the needle push-out blade 51 in preparation for ejection. It faces above the needle bend groove 2. In this case, in other words, the staple group 7 has a size that corresponds to the thickness of the stacked paper sheets A.
9, when selecting the bottom frame 6 of this staple storage body 60.
The stopper body 7 has the left and right sliding pieces 8 inserted into the left and right guide long grooves 6 in the bottom plate part 72 of the magnet body 10.
However, when this staple storage body 60 is rotated relatively strongly in the left and right direction around the suspension rod 28, the bottom plate portion 72 of the staple storage body 60 resists the magnetic force and becomes a magnet. Therefore, the staple storage body 60 can be rotated relatively easily and the staple group 79 can be selected easily.

Next, when the operation handle 40 is rotated downward again, the operating body 14 is rotated downward as described above, and the paper pressing surface 61a at the lower end of the front frame 61 of the staple storage body 60 is pressed against the weight on the needle receiving plate 3. It is polymerized on the stack of paper leaves A. Then, when the operating handle 40 is pushed further downward, the operating handle 40 rotates around the rotation center axis 38 with the Kosuru spring 58,
59 and is rotated downward while moving within the left and right guide grooves 46 and lowered, the elevating frame 48 is vertically moved through the long guide groove 49 and the guide locking rod 50. be lowered. Further, due to the lowering of the elevating frame 48, the needle pushing blade 51 and the guide pin 54 of the needle pushing blade 51 are moved to the back side of the selected scale display of the blade guide portion 53 of the actuating body 14 and the indicator 64 of the front side frame 61. As it is lowered along the sliding groove 66, the needle at the tip of the needle group 79 is pushed out by the needle pushing part 52 at the lower end of the needle pushing blade 51 and separated from the second needle. The needles are pushed out from between the guide plate 83 and the inner lower guide surface 67 of the front frame 61 by the needle extruder 53, which is further lowered, against the elasticity of the guide plate 83, and are piled up. The lower portions of both legs of the paper sheet A are bent by the needle bending grooves 2 of the needle receiving plate 3, and the stacked paper sheets A are stapled by the staples.
In this case, the horizontal part of the most advanced staple separated from the second staple is lowered while being resiliently supported by the guide plate 83, and both the left and right legs of the cat are placed on the left and right guide rails 77. Since the staple is lowered while being guided by the guide surface 81 of the stopper 80 that has expanded outward, the staple is lowered vertically without tilting, and the stacked sheets A are struck vertically. It can be stored neatly and neatly.

Next, when the downward rotation of the operating handle 40 is released, the operating handle 40 is rotated upward about the rotation center axis 38 by the restoring force of the coil springs 58 and 59, and the left and right guide grooves 46
The lifting frame 48 is pulled up by the operating rod 47 that moves, and as the lifting frame 48 is pulled up, the needle push-out blade 51 moves between the blade guide portion 53 of the operating body 14 and the front frame 6.
It is pulled up vertically via the long sliding groove 66 and the guide pin 54 engaged therewith. The lower part of the long guide groove 49 of the lifting frame 48 is locked to the guide locking rod 50, thereby locking the upward rotation of the operating handle 40, and the guide pin 54 is connected to each of the long sliding grooves 66. It is engaged in a common arcuate sliding groove 65 and is prepared for the rotation of the staple storage body 60 for selecting the next staple operation or the next staple group 79, and also for the needle extrusion of the needle extrusion blade 51. The section 52 is pulled up to the position of the blade guide section 53 in preparation for the next stapling operation.

In addition, as the operation handle 40 and the needle pushing blade 51 rise, the actuating body 14 is rotated upwardly about the rotation center axis 18 via the left and right guide holes 19 and the guide support shaft 21 due to the return force of the coil spring 95. By locking the left and right guide holes 19 of the operating body 14 with the guide shaft 21, the upward rotation of the operating body 14 is locked, and the front frame 6 of the staple storage body 60 is locked.
1 is opened between the paper pressing surface 61a and the needle receiving plate 3, and the stacked sheets A that have been stapled together are pulled out and prepared for the next binding operation.

Furthermore, when the staple housing 60 is similarly pulled up by the upward rotation of the actuating body 14 and the bottom plate portion 72 of the bottom frame 63 releases the pushing movement of the passive rod 109, the restoring force of the coil spring 110 When the swing frame 98 is rotated back around the rotation center axis 99 and the passive rod 109 is pushed up in preparation for the next forward movement, the interlocking pin 117 is pulled down and the movable The gauge piece 114 is lowered relative to the fixed gauge piece 124 in preparation for measuring the thickness of the next pile of paper sheets A for binding.

Note that the needle extrusion portion 52 of the needle extrusion blade 51 is
When the slider 85 of the sliding shaft 86 is pulled up to the position of the blade guide part 53 of No.
0 is moved forward along the sliding shaft 86 by the operation of
This slider 85 pushes the stapler group 79, and the second stapler moves into the needle pushing part 53 in preparation for the next binding operation.
and the guide surface 6 of the front side frame 61
7 is supported.

In addition, in the implementation, the left and right guide long grooves 6 that guide the movement of the left and right sliding pieces 8 of the stopper body 7 are
