Thereby, the support arm 11 is pivotally supported by the rotating part 13 so as to be rotatable in the horizontal direction around the protruding shaft part 20. If the upper piece 18 and the lower piece 19 are spread out, the support arm 11 can be easily detached from the base base 1.

  Thus, the support arm 11 is provided so as to be retractable and retractable on the base table 1 by rotation. At the time of storage, the edge side support portion 11b and the inner side support portion 11c of the support arm 11 are fitted into the storage portion 12 formed on the side edge portion 1c and the front edge portion 1d of the base stand 1, and the support arm 11 As shown in FIG. 1, the entire upper surface 11 d cooperates with the base table 1 to form a substantially same plane as the paper placement surface 1 a on the upper surface of the base table 1. At the time of storage, as shown in FIG. 5, the engagement convex portion 21 of the support arm 11 is held at a position where it engages with the engagement hole 15 of the rotating portion 13. When the support arm 11 is pulled out and rotated, the upper piece 18 of the support arm 11 is deformed upward, and the engagement protrusion 21 is disengaged from the engagement hole 15 and is engaged with the next engagement hole 15. In the same manner, the engagement projection 21 is disengaged from the engagement hole 15 and is engaged with the next engagement hole 15 beyond the engagement hole 15. As described above, the rotating portion 13 of the base base 1 and the support arm 11 is configured with a click mechanism in which the resistance changes whenever the engaging convex portion 21 gets over the engaging hole 15. The arm 11 cannot be freely rotated and can be held at a predetermined opening angle. The opening angle is preferably set to 0 degrees during storage, 45 degrees in the middle, and 90 degrees in the maximum.

  Since the engaging convex portion 21 of the lower piece 19 of the support arm 11 is engaged with the annular groove 17 on the lower surface of the rotating portion 13, the engaging convex portion 21 is not moved when the supporting arm 11 is rotated. The lower piece 19 does not bend and deform below the lower surface of the base base 1 like the upper piece 18 because it always moves in a state of being accommodated in the annular groove 17. Accordingly, the base 1 does not lift from the installation surface b when the support arm 11 is rotated, and the support arm 11 can be smoothly rotated.

  Next, as shown in FIGS. 2 and 7, engagement concave portions 22 are formed on the upper and lower surfaces of the intermediate portion of the storage portion 12 of the base 1. A guide groove 23 that opens to the outside of the storage portion 12 is continuously formed in the lower engaging recess. On the other hand, an engaging convex portion 24 that can be engaged with each other is formed at a position corresponding to the engaging concave portion 22 and the guide groove 23 of the base stand 1 in the intermediate portion of the edge side supporting portion 11b of the supporting arm 11. ing. Thereby, when the support arm 11 is retracted, the engaging convex part 24 engages with the engaging concave part 22. At this time, the engaging convex part 24 at the lower part of the edge-side support part 11 b is smoothly guided from the guiding groove 23 of the storage part 12 and engages with the engaging concave part 22. Since the engaging portion (engaging concave portion 22 and engaging convex portion 24) that can be engaged with each other is formed at a portion where the storage portion 12 and the edge side support portion 11b are in contact with each other in the vertical direction, the support arm 11 is in the retracted state. It is held and will not rotate freely.

  Further, a semicircular cutout 25 is formed at the tip of the inner support portion 11c of the support arms 11 on both sides. The notch 25 is preferably about half the size of a fingertip. When the support arm 11 is retracted, the notch 25 of the support arm 11 on both sides forms a space that allows a fingertip to enter. Thus, it is preferable that the front ends of the support arms 11 on both sides are arranged in a butt shape during storage.

  As shown in FIG. 1, a gap 26 is formed at a corner between the upper surface 1a of the base base 1 and the upper surface 11d of the stored support arm 11 so that a fingertip can be inserted.

  Further, a scale groove 27 is formed on the edge side support portion 11b of the support arm 11 as a guide for the binding position of the paper a.

  Next, when using the stapler having the above configuration, first, a finger is put into the gap 26 formed at the corner of the base 1 in the state shown in FIG. 1 and the inside of the support arms 11 on both sides is pushed. The arm 11 is pulled out and rotated. At this time, the finger may be put on the notch 25 at the tip of the support arm 11 and rotated. As shown in FIG. 2, the support arms 11 are each rotated 90 degrees and held at their opening angles, and after positioning the positioning member, the edge a1 of the paper a is placed on the paper placement surface 1 a and the upper surface of the support arm 11. Place on 11d and set. Since the support arm 11 cooperates with the base base 1 to form a substantially same plane as the paper placement surface 1a, the placement area of the paper a is increased by the amount the support arm 11 is pulled out on both sides. Since the portion of the paper a protruding from the base 1 is supported by the support arm 11, the periphery of the clinch groove 2 of the paper a is held flat. At this time, the edge side support portion 11b of the support arm 11 supports the edge portion a1 of the portion of the paper a that protrudes from the base 1 from below. Further, since the inner support portion 11c supports the sheet center side of the edge portion of the sheet a protruding from the base table 1 from the lower surface side, it is more than the case of supporting only the edge portion of the sheet a protruding from the base table 1. The paper a can be supported in a stable flat posture.

  In this state, the handle 3 is pushed down to drive the driver plate 6 to drive out the staples, so that the staple legs penetrate the paper a placed on the paper placement surface 1a and further press against the clinch groove 2. The sheet a can be bound by being bent. When the binding is completed, the handle 3, the driver arm 4 and the magazine 5 are returned to the initial state shown in FIG. Is done. Since the sheet a is bound in a flat state, the upper and lower sheets a are bound uniformly from top to bottom without being displaced. For this reason, there is no distortion or deformation, and the finish is good.

  When two places are bound, the side edge of the paper a is aligned with the scale groove 27 of the support arm 11 so that the spelling positions from both ends can be made exactly the same.

  Further, when binding the paper a, the support arms 11 may be rotated by 45 degrees as shown in FIG. The support arm 11 is held by the click mechanism at this opening angle. The corners of the sheet a are inserted from the openings 10 of the positioning member 8 and the edges a1 and a2 adjacent to the corners are placed on the support arm 11. Since the portion of the support arm 11 that protrudes from the base table 1 is supported by the support arm 11, the sheet a is held in a flat state. Also in this case, the inner support portion 11c supports the sheet center side of the edge of the sheet a protruding from the base 1 from the lower surface side, so that the sheet a can be supported in a stable posture. Further, both edges of the corner of the sheet a are aligned with the marks 9 on both sides of the clinch groove 2. In this state, the handle 3 is pushed down to perform the binding operation, so that the upper and lower sheets a are bound uniformly from the top to the bottom without being displaced.

  After completion of the spelling operation, the support arms 11 on both sides may be stored in the storage unit 12 of the base 1. At this time, since the engaging convex portion 24 of the support arm 11 engages with the engaging concave portion 22 of the storage portion 12, the support arm 11 is held in the retracted state and does not rotate excessively.

  According to the above-mentioned stapler configuration, the support arm 11 extends along the side edge 1c of the base stand 1 and the base end portion 11a pivotally supported by the base stand 1 and the base end portion 11a. A support arm that supports the paper a. The support arm 11b extends to the edge side support 11b and the inner support 11c extends from the edge support 11b along the front edge 1d of the base 1. The total length of 11 can be maximized.

  Further, since the support arm 11 cooperates with the base table 1 in the retracted state so as to form the substantially same plane as the paper placement surface 1a, the support arm 11 has an appearance that can be seen integrally with the base table 1, and the whole is shown. Since it can fit within the width of the base 1, it can be made compact, and the paper a can be widely supported on substantially the same plane.

  In addition, since the support arm 11 is formed so that the upper and lower portions thereof are symmetrical with respect to the center line p, the left and right support arms 11 can be used in common by using the inverted upper and lower sides. There are benefits.
