Description

  The present invention relates to a stapler with a scale that allows a staple to be correctly driven and bound at a predetermined position of a document.

  The stapler is a tool for binding paper by driving a “ko” -shaped needle into paper and bending the leg tip portion flat from both sides. The stapler is one of the tools necessary for various tasks, and each individual possesses at least one. The office is equipped with staples with large, medium and small “ko” shaped needles so that they can be used properly according to the number of papers to be closed (document thickness).

  By the way, it is possible to bind a predetermined number of documents using a stapler, but in this case, it is necessary to prevent the positions of the needles from varying. In general, the two U-shaped needles are driven into both sides while leaving a binding width of an appropriate width, but this is not preferable in a binding method in which the positions of both needles vary. If you're binding private documents, don't worry too much, but staples for those who are in the profession that the documents are submitted to clients (for example, land and house investigators, judicial scriveners, administrative scriveners, etc.) There is a possibility that the variation of the needles that are driven in will be suspected even in the contents of the document that becomes the product.

  However, it is not easy to correctly drive both needles while leaving a predetermined binding margin, and most of them are uneven. A document stapler is attached to a large stapler that can be driven into a large U-shaped needle. Since the stopper is slidable, the width of the binding margin of the document can be freely adjusted. However, such a stopper is not provided in a small stapler used every day.

The “stapler original positioning tool” according to Japanese Patent Application Laid-Open No. 2004-74338 does not have an adjustable large original stopper in a small stapler, and cannot align the needle with an accurate position because it aligns with a reference amount. Even if there was a stopper, it was inefficient because the original had to hit a small stopper because of its small size.
Therefore, the large stopper and the holding part applied with the pressure set at the bottom of the stapler are integrated, can be set at any position, can be easily attached and removed, and can be composed of one part Therefore, there is no breakdown and it is inexpensive.

A “stapler document positioning device” according to Japanese Patent Application Laid-Open No. 2005-319565 is a staple document positioning device that can be attached to a stapler and can arbitrarily adjust the position of a needle that binds the document. This is a document positioning device for mounting a transparent acrylic plate or the like with a scale on the side from which the staples come out. Therefore, since the document positioning tool is fixed and it is not necessary to adjust the position of the tool itself, the conventional document positioning stopper is not required, so that the adjustment work of this stopper is not required, and labor is saved. I can do it.
"Stapler original positioning tool" according to Japanese Patent Application Laid-Open No. 2004-74338 "Stapler original positioning device" according to Japanese Patent Application Laid-Open No. 2005-319565

  As described above, a stapler provided with a positioning stopper is known so that a U-shaped needle is driven into a predetermined position when a plurality of documents are bound by a stapler. However, the stapler described above is troublesome because a separate member must be attached as a positioning stopper. Moreover, since it is a removable member, it may be lost. The problem to be solved by the present invention is this problem, and provides a stapler with a scale that can be easily aligned by a scale formed on the stapler without attaching a positioning stopper as a separate member.

  The stapler has a base member, a needle housing member that accommodates a U-shaped needle, and a lever member that presses the needle from above to hold a document between the base member and drive it. The needle housing member and the lever member are pivotally supported so as to swing on a shaft provided on the base side of the base member. The needle accommodating member accommodates a needle member formed by connecting a plurality of U-shaped needles, and a spring for pressing the needle member from the base side toward the distal end is attached. A nail that drives the needle is raised.

  By the way, although the above-mentioned basic structure as a stapler is the same as that of a conventional stapler, it is not limited to this basic structure. That is, the specific means for driving the U-shaped needle into a document and binding it is not limited. The stapler of the present invention is characterized in that a scale is formed on the surface of the lever member. The reference line of the scale is a position of a claw provided at the tip of the lever member, and a plurality of scale lines are formed at regular intervals from this position. The scale line may be printed or engraved on the surface of the lever member, and it is necessary that the scale line does not disappear during use, and the specific means is not limited.

  Thus, the stapler of the present invention forms a scale on the surface of the lever member, and the reference line of the scale is the position of a claw provided at the tip of the lever member. That is, it is the position of the needle that can bind the document by driving, and the binding margin can be determined by aligning the binding side edge of the document with this scale. Therefore, when a document composed of a plurality of sheets is bound by stapler, the position of each needle does not vary and the appearance is complete by aligning with respect to the scale. The stapler of the present invention does not need to be attached with a special positioning member, so that the stapler can be efficiently performed.

It is the stapler of this invention which formed the scale, (a) is a top view, (b) is a front view. (A) is a needle | hook accommodation member which comprises the stapler of this invention, (b) is AA sectional drawing of (a). The lever member which comprises the stapler of this invention. The tip of the base member. When binding documents using the stapler of the present invention.

  FIG. 1 is a specific example showing a stapler according to the present invention, wherein (a) shows a plan view and (b) shows a front view. This stapler is for binding a relatively thin document. In FIG. 1, 1 is a base member, 2 is a needle accommodating member, 3 is a lever member, and both support portions are provided on the base side of the base member 1. 4 and 4 are erected, and a shaft is provided across the support portions 4 and 4. The needle housing member 2 and the lever member 3 are pivotally supported on the shaft so as to be swingable.

  The base member 1 has a structure in which a resin base is combined on the lower side of a metal plate, and the lever member 3 is covered with a resin cover so as to cover a metal frame. The stapler has a spring attached to the base side of the base member 1, and pushes up the needle housing member 2 and the lever member 3 as shown in FIG. 1 (b), and between the base member 1 and the needle housing member 2. Forms a space 5. Therefore, when binding a document, if the document is set at the tip of the base member 1 and the lever member 3 is pushed down, the needle housing member 2 is also lowered at the same time, and the document is moved between the base member 1 and the needle housing member 2. If the lever member 3 is further pinched and the lever member 3 is pushed down, the needle housed in the needle housing member 2 can be lowered and driven into the document for binding.

  FIG. 2 shows a state in which the needle member 6 is housed in the needle housing member 2, but the needle member 6 is formed by connecting a plurality of U-shaped needles 7, 7,. When binding, it will be driven separately one by one. Here, the needle housing member 2 has a U-shaped cross section that opens upward as shown in FIG. 2B, and a U-shaped needle member 6 opens downward in the needle housing member 2. It is accommodated in a state and is pressed toward the distal end by the pressing member 8.

  That is, the coil spring 9 is attached to the base side of the pressing member 8, and the spring force of the coil spring 9 is urged by the pressing member 8. Accordingly, the needle member 6 hits the tip stopper 10 of the needle housing member 2, and one needle 7 is pressed from above by the claw 11 provided at the tip of the lever member 3. As a result, the needle member 6 is separated from the needle member 6 and is separated from the document. Is bound. A narrow groove 12 through which one needle can pass is formed at the tip of the bottom plate of the needle housing member 2, and the U-shaped needle 7 pressed and separated by the claw 11 passes through the groove 12 and is driven into a document. .

  FIG. 2A shows a state in which a part of the needle member 6 is cut away so that the groove 12 formed at the tip of the needle housing member 2 can be seen. The needle housing member 2 is pivotally supported by a shaft 14 provided on the support portions 4 and 4 erected on the base side of the base member 1. The shaft 14 shown in the figure is attached across both support portions 4 and 4 of the base member 1.

  FIG. 3 shows the inside so that the structure of the lever member 3 can be seen. The lever member 3 is provided with a resin cover 16 that covers a frame 15 having a U-shaped cross section, and a pressing member 13 is swingably attached to the shaft 14 inside the frame 15. The shaft 14 is provided on the support portions 4 and 4 erected on the base side of the base member 1, and the lever member 3 is pivotally supported by the shaft 14 so as to swing.

  The pressing member 13 is energized by a leaf spring 18 attached to the frame 15, and is pushed upward in the state shown in FIG. However, the tip protrusion 17 is fitted in the guide groove formed in the claw 11, and the upward push-up is restricted. In combination with the needle housing member 2, the pressing member 13 can be pressed so that the needle member 6 housed in the needle housing member 2 does not come off in the state shown in FIG.

  A claw 11 is provided at the tip of the frame 15, and the claw 11 is a plate-like body having a thickness capable of pressing a single U-shaped needle. If the lever member 3 is pushed down, the claw 11 is provided. Can contact and press the connecting portion that connects the legs of the U-shaped needle. The needle 7 passes through the tip groove 12 of the needle housing portion 2, and at the same time, the claw 11 can be fitted into the groove 12.

  FIG. 4 shows the tip of the base member 1. Bending grooves 19a and 19b are formed in a pair at the front end of the base member 1, and both legs of the U-shaped needle 7 are driven to pass the document, and both legs are inside by the bending grooves 19a and 19b. Can be folded. For this purpose, a document composed of a plurality of sheets is bound by the needle 7.

  By the way, when binding a document in which a plurality of sheets of paper are overlapped, alignment is performed with reference to a scale formed on the surface of the lever member 3 with the binding side disposed at the tip of the base member 1. Since the reference line 20 serving as the reference point of the scale is formed at the position of the claw 11, the needle 7 is driven into the position of the reference line 20, and the needles 7, 7. Staplers can be stapled in a well-aligned position.

  FIG. 5 shows a stapled state when binding a document. Of the scale lines formed on the surface of the lever member 3, scale lines 21a, 21b, 21c,... Are provided at intervals of 5 mm with the reference line 20 as a base point. Therefore, when binding a document, the binding side of the document placed on a table or desk is set between the base member 1 and the needle housing member 2, and the binding side edge 22 of the document is aligned with the scale line 21b. I can do it. If the binding side edge 22 is aligned with the scale line 21b and stapled, the distance between the needle 7 and the binding side edge 22 is 1 cm. Similarly, if the staple line 21a is stapled to coincide with the scale line 21a, the interval between the binding side edge 22 and the needle 7 is 5 mm.

  Therefore, when two places of the A4 version document are stapled, the two needles 7 and 7 are arranged without variation, and the appearance of the document is improved. Conventionally, there are many cases in which the misaligned needle 7 is extracted and stapled again. However, if the stapler of the present invention is used, the individual needles 7 and 7 are correctly stapled at predetermined positions, and the appearance of the document is changed. improves. By the way, the structure of the stapler illustrated in FIGS. 1 to 4 described as the embodiment of the present invention is only one specific example, and is a stapler characterized by forming a scale on the surface of the lever member 3 to the last. .
