DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a staple attached to an electric stapler and used for spelling a material to be sewn, and relates to a refill staple for refilling when used in a spelling operation.

[0002]

2. Description of the Related Art In general, an electric stapler is formed by bending a connecting staple formed by connecting a large number of straight staples into a U-shape in order from the top, and then driving the staple into a material to be sewn. When staples for refilling are loaded and staples are consumed due to repetition of the spelling operation, the staples have been replaced by replacing the staple cartridges.

However, in this method, the old cartridge is discarded, which is not preferable from the viewpoint of saving resources, protecting the natural environment, and the like. Therefore, the staple cartridge has been used as it is, and only the staple has been refilled. This type of refill staple is formed in a size that can be loaded into an electric stapler, and is supplied to the market in a state wound with a paper tape or the like.

[0004]

However, there is a problem in workability when the conventional refill staple is loaded into the staple cartridge of the stapler main body. For example, the staple cartridge is erroneously turned upside down with respect to the loading port of the staple cartridge. Once it was inserted, removal was very troublesome.

[0005] In view of the above problems, it is an object of the present invention to provide a refill staple that can be easily and accurately loaded into an electric stapler.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a refill staple provided for an electric stapler according to the present invention is a refill staple to be replenished as necessary to an electric stapler, Stacked staples formed by connecting straight staples in a sheet shape are stacked in multiple stages to form a block, and the periphery is wound with a binding tape, and a tab is formed at the tip of the binding tape,
The width of the tab is larger than the width of the connection staple loading port of the electric stapler.

Incidentally, instead of forming the connecting staples in a block shape, a connecting staple formed by connecting a large number of straight staples in a long band shape may be formed in a roll shape. Good.

[0008]

FIG. 1 is a perspective view of a staple for refilling. A staple A for refilling is a connecting staple 1 (usually a sheet staple or a sheet) formed by connecting a number of straight staples in a sheet shape. Staples) are stacked in multiple stages to form a block. The periphery of the block-shaped staple is wound and bound by a paper or plastic binding tape 2.
A tab 3 is formed at the tip of the binding tape 2. FIG.
As shown in (a), the width of the tab 3 is formed to be larger than the width of the staple loading port 5 provided in the staple cartridge 4 of the electric stapler.

According to the above configuration, when the staple A for refilling is loaded into the loading port 5 of the staple cartridge 4 of the electric stapler, the staple A is turned upside down and loaded in an incorrect state, that is, as shown in FIG. If the tab 3 is to be attached to the loading port 5 first, the tab 3 does not enter because the width of the tab 3 is larger than the width of the loading port 5. Therefore, the operator easily notices that the insertion is wrong. On the other hand, when the cartridge is correctly loaded as shown in FIG. 3B, that is, when the cartridge is loaded from the loading port 5 with the tab 3 backward, the cartridge is mounted in a correct state. After attaching the binding tape 2
The binding tape 2 may be cut off by pulling strongly.

As described above, since the width of the tab 3 is formed so as to be larger than the width of the staple loading port 5, it is effectively prevented that the tab 3 is attached by mistake, and the loading operation for easily and correctly refilling is always performed. Can be performed.

Next, the staple B for refilling shown in FIG. 3 is a connecting staple 1 formed by connecting a number of straight staples into a long band by connecting staples 26 (see FIG. 4).
A is formed into a roll shape, and is generally called a roll staple. As shown in FIG. 4, a paper or plastic binding tape 2 is connected to an end portion thereof through an adhesive tape 7, Further, a tab 3 is adhered to an end of the binding tape 2. In addition, connection staple 1
Adhesive tape 7 than the adhesive force between the end of A and the adhesive tape 7
It is set so that the adhesive force between the binding tape 2 and the binding tape 2 or the adhesive force between the binding tape 2 and the tab 3 becomes stronger. The binding tape 2 is wound around the roll-shaped connecting staples 1A one or more times and adheres the overlapping inner and outer superposed surfaces 2P to hold and bind the connecting staples 1A in a roll shape.

The width of the tab 3 is formed to be larger than the width of the staple loading port 5 provided in the staple cartridge of the electric stapler.
Also, one side 9 of the tab 3 is cut off diagonally. Further, an arrow mark 25 is displayed on the surface of the tab 3.

The refill staples are shown in FIGS.
Is loaded into the roll staple cartridge 10 shown in FIG. The roll staple cartridge 10 is provided with a roll staple storage section 11 and a staple feed passage 12 in a cartridge body 10a.

The lower portion of the storage section 11 is opened, and the outermost end of the roll staple is led out from the opening 13 so as to pass through the staple feed passage 12. Further, a cap 14 is attached to an upper portion of the storage section 11, and the roll staple is configured so that the cap 14 can be opened and stored in the storage section 11.

The staple feeding passage 12 is continuous with the opening 13 of the storage portion 11 and is formed between the upper guide plate 15 and the lower guide plate 16. The pawls 17 are arranged to be inclined forward, so that the staples that have moved forward of the feed passage 12 do not move backward. The rear part of the lower guide plate 16 is open. The feed plate 1 is provided on the lower surface side of the lower guide plate 16.
8 is disposed so as to be movable back and forth. Three feed claws 19 are fixed to the upper surface of the feed plate 18 so as to be inclined forward, and the feed claws 19 protrude into the staple feed passage 12 from an open portion of the lower guide plate. The feed lever 20 is formed so as to be exposed downward from the lower surface of the feed plate 18. The feed lever 20 is formed so as to be able to move inside the opening hole 21, and this movement is the movement range of the feed plate 18.

Reference numeral 22 denotes a ratchet lever.
2 is connected to the feed plate 18 in the cartridge body. The ratchet lever 22 is always urged forward by a compression spring 23, and the feed plate 18 is also urged to move forward.

In the above configuration, when the cap 14 of the staple cartridge of the electric stapler is opened as shown by the dotted line in FIG. 6 and the staple B for refilling is loaded into the storage portion 11, as shown by the dotted line in FIG. Even if you try to enter from tab 3, it does not enter. Inversely, if the cut side 9 of the tab 3 is inserted into the right or left side, the tub 3 can be correctly loaded into the storage portion 11. Further, when the cap 14 is closed as shown by a solid line in FIG. 6, the tab 3 is exposed to the outside. Therefore, by pulling the binding tape 2 in the direction of the arrow mark 25 of the tab 3, the roll-shaped connecting staple 1A is stored. It rotates within the part 11 and its tip is drawn out of the storage part 11. Finally, when the binding tape 2 is pulled strongly, as shown in FIG. 7, the adhesion between the tip of the connection staple 1A and the adhesive tape 7 is released, and the binding tape 2 is separated. Then, as shown in FIG. 8, after the leading end 24 of the connection staple 1A is slightly introduced into the feed passage 12 from the opening 13, the feed plate 18 is moved forward and backward with the feed lever 20, as shown in FIG. In this case, the feed staple 19 of the feed plate 18 engages with the connecting staple 1 </ b> A. When the roll staple is moved backward, the roll staple cannot move backward because the check pawl 17 is engaged with the roll staple. In this manner, the roll staple can be fed out by the movement of the feed lever 20.

As described above, since the width of the tab 3 is formed to be larger than the width of the staple loading port 5,
It is effectively prevented from being attached by mistake.

Further, since one side 9 of the tab 3 is cut off, it is possible to correctly grasp the loading direction and load.

Further, since an arrow mark is displayed on the surface of the tab 3, it is easy to understand that the tab 3 is pulled, and the workability is good.
