A paper pressing protrusion 61 having a lower surface 6b that is in contact with the upper surface 12a of the paper table 12 with paper sheets interposed therebetween is provided so as to be parallel to the lower surface of the paper table 12. The paper presser 6 is a part of the paper positioning member 4 which is a resin member as described above, and can be retracted upward, that is, in a direction away from the paper table 12 by elastic deformation. When the paper sheet P is in contact with the paper table 12, both sides of the paper sheet P are pressed by the paper pressing protrusion 61 with the folding ridge line Pa interposed therebetween.

  A procedure in the case of forming a booklet by binding the paper sheets P that are previously folded along the folding ridge line 12b using the stapler S according to the present embodiment will be described below. First, as shown in FIG. 9, the anvil 14 and the staple driving unit 2 are set to the second posture. Next, as shown in the figure, with the folded ridge line Pa of the paper sheet P to be a booklet facing the ridge line 12b of the paper table 12, the paper sheet P is placed on the paper presser 6 and the paper sheet. Insert into the space between the table 12. If the number of paper sheets P is large, the paper presser 6 is elastically deformed to expand the space between the paper table 12 and then the paper sheets P are inserted into the space. Then, one edge of the paper sheet P is brought into contact with the paper sheet contact surface 51 a of the positioning portion 51 of the depth gauge 5. Then, as shown in FIG. 10, an operating force is applied to the handle 3 to bring the staple driving unit 2 and the staple receiving unit 1 closer to drive the staple into the paper sheet P. By performing such an operation, staples are arranged on the folding ridge line Pa of the paper sheet P, and the paper sheets P are bound by this staple to form a booklet.

  On the other hand, when the stapler S according to the present embodiment is used as a normal stapler, the anvil 14 and the staple driving unit 2 are in the first posture as shown in FIGS. 1 to 4 and are bound to the upper surface 6a of the paper presser 6. After the paper sheets P are arranged, as shown in FIG. 6, an operation force is applied to the handle 3 so that the staple driving unit 2 and the staple receiving unit 1 are brought close to each other to drive the staples into the paper sheet P. . At this time, the upper surface 6a of the paper presser 6 functions as a paper table of a normal stapler.

  As described above, according to the configuration of the present embodiment, the depth gauge 5 and the paper presser 6 are moved integrally, and the paper sheet P is arranged in the space between the paper presser 6 and the paper table 12. The paper sheet P is pressed between the paper sheet P and the anvil 14 in a state where the paper sheet P is pressed against the paper table 12 by the paper presser 6 by a series of operations of hitting the paper sheet P against the depth gauge 5. Positioning can be performed easily. In addition, by performing the operation of driving staples in a state where the paper sheet P is pressed against the paper table 12 by the paper presser 6, the staples can be obtained even when the stapler S is gripped and the above operation is performed. The operation of driving into the position can be performed reliably.

  Further, the upper surface 12a of the paper table 12 includes a ridge line 12b opposed to the folded ridge line Pa of the paper sheet P that is folded along a preset folded ridge line Pa, and the paper presser 6 is configured to be the paper sheet. Since it is possible to press both sides of the folded ridge line Pa of the paper sheet P attached to the table 12, when binding the paper sheet P on which the folded ridge line Pa is formed in advance to form a booklet, The folding ridge line Pa of the paper can be positioned reliably.

  Furthermore, since the moderation mechanism K for selectively locking the depth gauge 5 at any of a plurality of attachment positions is provided between the staple receiving unit 1 and the depth gauge 5, the depth Positioning of the gauge 5 with respect to the staple receiving unit 1 can be easily performed.

  In addition, the staple launching unit 2 and the anvil 14 staple staples in a direction perpendicular to the longitudinal direction of the paper table 12, and staples in a direction parallel to the longitudinal direction of the paper table 12. Therefore, the stapler S can be used not only for forming a booklet but also by stapling staples mainly in the corners of the paper sheet P. It can also be suitably used as a normal stapler S for binding paper sheets P.

  Since the paper presser 6 can be retracted in a direction away from the paper table 12 by elastic deformation, a booklet is formed by binding a large number of paper sheets P using such a stapler S. Can do.

  The present invention is not limited to the embodiment described above.

  For example, the moderation mechanism between the depth gauge and the staple receiving unit may be omitted. In this case, in order to easily adjust the position where the staple is to be driven, a scale indicating the distance between the anvil and the depth gauge may be provided on the staple receiving unit. When such a mode is adopted, as an example of means for positioning the relative position between the depth gauge (and a paper presser provided integrally with the depth gauge) and the staple receiving unit, a female screw provided in the depth gauge A configuration in which a male screw member is screwed to the portion and a tip thereof is pressure-bonded to the staple receiving unit is conceivable.

  Further, instead of integrally configuring the depth gauge and the paper presser, a mode in which a paper presser formed separately from the depth gauge is attached in a state of being movable integrally with the depth gauge may be employed. In this case, the paper presser may be detachable from the depth gauge.

  Further, the paper presser may be capable of pressing only one side across the folding ridge line of the paper sheet, or may be capable of pressing only on the folding ridge line.

  In addition, when the stapler of the present invention is used only for the purpose of binding a sheet of paper with a bent ridge line formed in advance to form a booklet, the staple driving unit and the anvil are stapled in a direction parallel to the longitudinal direction of the paper table. You may make it fix to the attitude which strikes and caulks. In this case, the upper surface of the paper press does not necessarily have to be parallel to the staple driving unit.

  In the above-described embodiment, the mounting positions of the integrally provided depth gauge and the paper presser can be changed, but the relative positions of the depth gauge and the paper presser cannot be changed in the staple receiving unit. May be provided. In this case, the distance between the edge to which the depth gauge should strike and the stapling position of the staple can be always kept constant on the paper sheet.

  In addition, various modifications may be made without departing from the spirit of the present invention.
