Description

  The present invention relates to a technique for binding a sheet bundle in which a plurality of sheets are stacked.

  The organization of documents in office work occupies a large weight in the whole work. For example, when organizing documents, if there are multiple documents, first bind the documents using a stapler, stapler, etc., and then drill two holes (punch holes) for the file with a punch (for example, a punch). After that, the file was bound.

  For example, the paper binding machine disclosed in Patent Document 1 is characterized in that a staple is provided on the side of a punch for punching a file hole, and an operation lever for pushing the punch and the staple are connected. Thus, by operating the operation lever, the stapler and the punch for punching operate simultaneously, and the paper binding and the hole for file can be formed by one operation.

Japanese Utility Model Publication No. 5-31899

However, in the paper binding machine disclosed in Patent Document 1, the distance between the punch hole and the stapled portion by the stapler is fixed, and the distance between the punch holes is standardized. Depending on the paper size, the distance from the binding location to the paper edge may become longer. In this case, a large load may be applied to the binding needle according to the movement such as the end of the document bundle being rolled. In such a case, there remains a problem that the binding state is released, that is, the document is separated again. Further, there remains a problem that it is not possible to selectively and easily bind one place or a plurality of places at a time.
Note that even when a conventional stapler or stapler is used, when a sheet bundle in which a plurality of sheets are stacked is bound, the sheet bundle is punched using a punching punch (punching a punch hole). The needle and punch hole may overlap. Therefore, the binding process cannot be easily performed.

  The main object of the present invention is to provide a stapler capable of easily binding a bundle of sheets so as not to interfere with punch holes in advance according to the sheet size.

  The stapler according to the present invention is configured such that the first and second binding mechanisms that are arranged in parallel and bind a sheet bundle in which a plurality of sheets are stacked and the first and second binding mechanisms are relatively close to each other, or A slide mechanism that moves in a separating direction; a first extension portion that extends from the first binding mechanism toward the second binding mechanism; and the first binding mechanism that extends from the second binding mechanism. And a second extension portion extending toward the mechanism so as not to interfere with the first extension portion, and the first and second binding mechanisms are configured to be the first or second binding mechanism. It is possible to selectively perform a binding operation on one position on the sheet by the two binding mechanisms or a binding operation on a plurality of positions by the first and second binding mechanisms.

  According to the present invention, according to the sheet size, the sheet bundle can be easily bound in advance so as not to interfere with the punch holes.

FIG. 5 is a diagram for explaining a binding result for a sheet bundle different from FIG. 4.

  Hereinafter, embodiments will be described with reference to the drawings. The description will be given by taking as an example a binding device (stapler) that performs a binding process on a sheet bundle in which a plurality of sheets such as various sizes of paper and documents are stacked.

[Example Embodiment]
FIG. 1 is a top view for explaining an example of the configuration of the stapler according to the present embodiment.
A stapler 10 shown in FIG. 1 includes a first stapler 101, a second stapler 102, a first base (pedestal) 103 on which the first stapler 101 is placed, and a second stapler 102 on which the second stapler 102 is placed. 2 bases 104 (pedestals) and a slider 105. The first stapler 101 functions as a first binding mechanism, and the second stapler 102 functions as a second binding mechanism.

  The first base 103 and the second base 104 are configured to be slidable in the direction of the arrow in the drawing via an intermediate base 120 (see FIG. 2) described later. In other words, the first base 103 and the second base 104 can be moved in directions that are relatively close to or separated from each other. In this manner, the base (pedestal) of the stapler 10 is configured including the first base 103, the second base 104, and the intermediate base 120.

  The stopper 110 is a groove (a step portion) formed in the first base 103 and the second base 104, and the end portion of the sheet bundle inserted from the sheet bundle insertion direction shown in the figure is the step portion. The sheet bundle is positioned when the binding process is performed (see FIG. 3).

  The slider 105 has a convex portion at the left end when viewed from the front of the figure. The slider 105 is configured to be slidable in a direction (horizontal direction) orthogonal to the sheet bundle insertion direction relative to the first base 103.

  For example, a scale (A4 or the like) corresponding to the sheet size is attached to the surface of the slider 105, and the scale is aligned with the left end of the first base 103 and the sheet bundle is brought into contact with the convex portion. Accordingly, the sheet bundle can be positioned in the horizontal direction.

  The first stapler 101 functions as a first binding mechanism, and performs, for example, a binding process using a binding needle or a wireless binding process without using a binding needle on a sheet bundle after positioning at a binding position S1. It is.

  The second stapler 102 functions as a second binding mechanism, and performs, for example, a binding process using a binding needle or a wireless binding process without using a binding needle on the sheet bundle after positioning at the binding position S2. It is. Note that the first and second staplers are configured to be able to perform the binding operation individually.

Further, as shown in FIG. 1, the first stapler 101 is an arm that is a first extending portion that extends horizontally from the end on the sheet bundle insertion direction side toward the second stapler 102. 101a.
Similarly, as shown in FIG. 1, the second stapler 102 is moved horizontally from the position in the end direction on the sheet bundle insertion direction side so as not to interfere with the arm 101a. It has the arm 102a which is the 2nd extension part extended toward. The user can bind the sheet bundle by pressing the upper surfaces of the first and second staplers or the upper surfaces of the arms individually or simultaneously.

  When the arms 101a or 102b are pressed individually, one place on the sheet is bound, and when the arms 101a and 102b are pressed simultaneously, a plurality of places (two places) on the sheet are bound. become. As described above, the user can selectively perform the binding operation on one place on the sheet or the binding operation on a plurality of places.

  Scales such as “0”, “B5E”, and “A4E” are set on the surface (upper surface) of the arm 101a. Further, a scale such as “A4S”, “B5S”, and “B6S” is set on the surface (upper surface) of the arm 102a. The scales “A4E”, “B5S”, and the like mean standard sizes (A4, B5, etc.) and binding directions of sheets as sheets.

  For example, if the display direction is “E”, the long side is bound, and if the display is “S”, the short side is bound. Hereinafter, the relationship between the sheet size and the binding position will be described.

  For example, when binding a sheet bundle of A4 size (210 × 297 [mm]), it is necessary to select whether to bind the long side or the short side depending on the format of the file storing the sheet bundle. . In addition, if the distance from the binding position to the end of the sheet bundle becomes long, a large load is applied to the binding needle according to the movement of the end of the sheet bundle, and as a result, the binding state is released, that is, again. The sheet may fall apart.

  Therefore, for example, when binding the long side, the first and second staplers are slid to align the scale “A4S” of the arm 101a with the scale “A4E” of the arm 102a. By combining both scales, the interval between the binding positions S1 and S2 becomes an interval suitable for A4 size and long side binding. After that, if the sheet bundle is bound, the problem that the distance from the binding position to the end of the sheet bundle becomes long does not occur.

  In addition, by setting the scale in this way, it is possible to easily position the binding position suitable for the sheet size and the binding direction. Further, when the scales are adjusted, the distance between the first and second staplers may be increased. Even in such a case, the upper surface of the arms 101a and 102a can be pressed to perform the binding process.

  The setting of these scales and the combination thereof are examples, and can be arbitrarily set according to the shape of the sheet, the standard of the paper, and the like. For example, when the scale “0” of the arm 101a and the scale “A4E” of the arm 102a are combined, the interval between the binding positions S1 and S2 is an interval suitable for A4 size and short side binding. Can be set. Further, the distance from the sheet bundle end to the binding position can be arbitrarily set by setting the scale and a combination thereof. The scale set for each arm in this way is set based on the paper size standard, and the case where the long side of the paper is bound and the case where the short side is bound can be specified by the combination of the scales. Has been.

FIG. 2 is a top view showing a state in which the first and second staplers are slid.
As described above, each of the first and second bases is configured to be slidable in the direction of the arrow in the figure via the intermediate base 120. As shown in FIG. 2, the first and second staplers are slid on the basis of the scale corresponding to the size of the sheet bundle to be bound and the binding direction.

The intermediate base 120 shown in FIG. 2 has a scale M2 such as “0” or “1” on its surface (upper surface). The scale M2 exhibits the same function as the scale of each arm surface described above.
Specifically, for example, the scale “1” represents a position 1 [cm] away from the scale “0”, and the first and second are stepwise in units of 1 [cm] with respect to the scale “0”. Slide the stapler. As a result, the scale M2 can be set so that the binding positions correspond to the respective sizes in the order of sizes such as “B6E”, “B5S”, and “A4S”.

  Further, for example, the first and second staplers are slid stepwise in increments of 2 [cm] with reference to the scale “0”. As a result, the scale M2 can be set so that the binding positions correspond to each in the size order such as “B5E”, “A4S”, and “A3S”.

  Note that the first and second bases via the intermediate base 120 can be configured to be slidable by a predetermined unit distance (for example, every 5 mm) via a slide mechanism such as a ratchet, for example. Thus, the first base 103, the second base 104, and the intermediate base 120 function as a slide mechanism for the first and second staplers.

  FIG. 3 is a side view for explaining an example of the operation of the stapler. FIG. 3A is a side view of the stapler 10 shown in FIG. 1 when viewed from the right side. FIG. 3B is a side view schematically showing the case where the stapler 10 shown in FIG. 1 is viewed from the right side and the second stapler 102 is removed.

  As shown in FIG. 3A, the second stapler 102 is connected to the base 104 via the rotation shaft 132. When the user depresses the upper surface of the second stapler 102, the upper surface of the arm 102a, or the like, the sheet is turned toward the base side (a dotted arrow in the drawing) and the sheet bundle is bound at the binding position S2.

Further, as shown in FIG. 3B, the first stapler 101 is connected to the base 103 via the rotation shaft 131. When the user depresses the upper surface of the first stapler 101, the upper surface of the arm 101a, or the like, the sheet is turned toward the base side (indicated by a dotted arrow in the drawing) and the sheet bundle is bound at the binding position S1.
As described above, the user can press each of the first and second staplers individually or simultaneously.

FIG. 4 is a diagram for explaining the binding result for the sheet bundle.
FIG. 4 shows a result of binding of the sheet bundle in “A4E”, that is, A4 size and long side binding, and a result of punching (punching hole H) of the sheet bundle performed thereafter. In addition, the space | interval of two holes (punch hole H) for accommodating in a general file is represented in the figure as 8.6 [cm].

  As shown in FIG. 4, the two punch holes H are formed at symmetrical positions with respect to the center of the long side. The binding positions S1 and S2 exist on the outer side with respect to the punch holes, and exist at positions where the distance from the binding position to the sheet bundle end does not become long. Therefore, even if the end of the sheet bundle is curled, the sheets can be prevented from falling apart.

FIG. 5 is a diagram for explaining a binding result for a sheet bundle different from that in FIG. 4.
FIG. 5 shows “A3S”, that is, A3 size, and the binding result of the sheet bundle in the short side binding, and the result of punching (punching the hole H) of the sheet bundle performed thereafter. In addition, the space | interval of two general holes (punch hole H) is represented in the figure as 8.6 [cm].

  As shown in FIG. 5, the two punch holes are formed at symmetrical positions with respect to the center of the short side. Further, the binding positions S1 and S2 exist on the outer side with respect to the punch hole H, and exist at positions where the distance from the binding position to the sheet bundle end does not become long. Therefore, even if the end of the sheet bundle is curled, the sheets can be prevented from falling apart.

When the example shown in FIG. 4 and the example shown in FIG. 5 are compared, it can be seen that the distance between the punch hole H and the binding positions S1 and S2 is different in each example. In this manner, the stapler 10 can easily determine the binding position corresponding to not only the sheet size but also the binding direction.
In addition to the sheet size (paper size) described with reference to FIGS. 4 and 5, various sizes of paper can be applied.

As described above, in the stapler 10 according to the present embodiment, the sheet bundle can be easily bound in advance so as not to interfere with the punch hole according to the sheet size. Furthermore, it is possible to selectively and easily bind one place or a plurality of places at a time.
Further, since each arm extends from the first and second staplers, even if the first and second staplers are separated depending on the sheet size, the stapler is pressed during the binding process. Can be easily performed.

  The above description is for explaining the present invention more specifically, and the scope of the present invention is not limited to these examples. Various forms without departing from the gist of the present invention are also included in the present invention. For example, a part of the above-described embodiments may be appropriately combined.
