[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric stapler cartridge for sequentially feeding sheet staples stacked and stored in multiple stages from a needle outlet.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 4, a cartridge of this kind has a needle receiving portion (supporting both side edges of the lowermost sheet-like staple) 11 formed at the bottom of a sheet-like staple storing portion 10 and a needle outlet. The stapler 12 is provided at a predetermined position of the electric stapler main body.

[0003] By the way, at the time of spelling, a feeding means such as a feed belt and a feed roller provided on the electric stapler body comes into contact with the lower surface of the lowermost sheet-like staple 1a on the staple receiving portion 11, and the sheet-like staple is moved to the needle outlet. The sheet staple 1a is fed out from the feeding unit 12, and the feeding force is obtained by the frictional force between the feeding means and the sheet staple 1a. It is necessary to feed the product with the contact friction between the two eliminated. Therefore, the height h of the needle outlet 12 is not enough to be the same as the thickness of the sheet staple,
Usually, it must be set to about 1.5 times the thickness of the sheet staple.

Since the size of the needle outlet 12 of the cartridge is limited as described above, the sheet staple 1 stored in the cartridge may be subjected to vibration, impact, or the like during transportation or mounting on the electric stapler body. The lowermost sheet staple 1a is used alone or in a state where it overlaps with the sheet staple 1b thereon.
Occurs, which causes defective feeding.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cartridge for an electric stapler capable of solving the above-mentioned drawbacks and, in particular, effectively preventing sheet-like staples from protruding from a needle outlet of the cartridge.

[0006]

In order to achieve the above object, an electric stapler cartridge according to the present invention has a housing for stacking and storing a plurality of sheet-like staples formed by bonding straight staples in a sheet-like manner. A needle receiving portion for receiving both side edges of the lower surface of the sheet-like staple at the bottom of the storage portion, and the needle receiver is provided between the lower surface of the front wall portion of the storage portion and the needle receiving portion. In a cartridge formed with a needle outlet portion capable of leading a lowermost sheet-like staple on the upper portion of the storage portion, a front end of the lowermost sheet-like staple is located at a lower end of the front wall portion. It is characterized by being inclined to the extent that it engages.

[0007]

According to the above construction, the sheet-like staples in the cartridge are supported on the needle receiving portion, and after the cartridge is mounted on the electric stapler body, the feeding means thereof causes the sheet-like staples to be moved from the lowermost sheet-like staples. It is sequentially drawn out from the needle outlet.

Since the needle receiving portion is inclined such that the front end of the lowermost sheet staple engages the lower end of the front wall, the front end of the lowermost sheet staple is connected to the needle outlet. Never turn. Therefore, even if vibration, impact, or the like is applied when the cartridge is transported or when the cartridge is mounted on the electric stapler main body, the lowermost sheet-like staple is effectively prevented from jumping out to the needle outlet. Therefore, according to the cartridge, the feeding of the sheet-like staples can always be kept good.

[0009]

1 and 2 are a front view and a longitudinal sectional view, respectively, of an electric stapler cartridge. This cartridge has a storage section 2 for stacking and storing a plurality of sheet-like staples 1 formed by adhering and connecting a large number of straight staples in a sheet form. The upper and lower sides of the storage section 2 are substantially open, and a needle receiving section 3 for supporting the sheet-like staple 1 is formed on both sides of the bottom. The needle receiving part 3 is a side wall part 2 of the storage part 2.
a protrudes inward from the lower end of the lowermost sheet-like staple 1a and receives both side edges of the lower surface of the lowermost sheet-like staple 1a.

Further, between the lower surface of the front wall portion 2b of the storage portion 2 and the needle receiving portion 3, the lowermost sheet-like staple 1 on the needle receiving portion 3 can be led out of the storage portion 2. The needle outlet 4 is formed. The height dimension h of the needle outlet 4 is set to about 1.5 times the thickness of the sheet staple 1 as in the related art. Note that a guide plate 5 is formed so as to protrude forward from the lower surface of the front wall portion 2b.

The needle receiver 3 is formed so as to incline forward. As shown in FIG. 2, the degree of this inclination is such that the front end of the lowermost sheet-like staple 1a on the needle receiver 3 engages the lower end of the front wall 2b.

According to the above configuration, a large number of sheet-like staples 1 are stored in the storage section 2 in a multi-layered state.
The both side edges of the lowermost sheet-like staple 1a are needle receiving portions 3
Supported on top. The center of the lower surface of the lowermost sheet staple 1a is open. In a normal case, a lid is attached to the upper part of the cartridge, and a spring (not shown) for urging the sheet staple 1 downward is arranged between the lower surface of the lid and the uppermost sheet staple. .

In using the cartridge, the stapler is mounted at a predetermined position on the main body of the electric stapler. As shown in FIG. 3, the central portion of the lowermost sheet-like staple 1 a rides on the feeding means 6 and the support portion 7 provided on the electric stapler, and is lifted from the needle receiving portion 3. And it is drawn out from the needle outlet part 4 in this state. That is, the feeding means 6 of the sheet staple 1 is usually constituted by a feed belt, a feed roller and the like arranged below the sheet staple 1, and when these feeding means 6 rotate, the feeding means 6 and the sheet The sheet-like staple 1 is fed forward by a frictional force generated between the staple 1 and the staple 1.

By the way, the needle receiving portion 3 is inclined such that the front end of the lowermost sheet-like staple 1a engages with the lower end of the front wall portion 2b. Does not face the needle outlet 4.
Therefore, even if vibration, impact, or the like is applied when the cartridge is transported or when the cartridge is mounted on the electric stapler body, the lowermost sheet-like staple 1a is effectively prevented from jumping out to the needle outlet 4. Therefore, according to the cartridge, the feeding of the sheet-like staples 1 can always be kept good.

A molding means and a driver are arranged in front of the cartridge. The sheet-like staple 1 drawn out of the cartridge is sent out along a guide path formed between the guide plate 5 and the support portion 7 on the electric stapler side, and is formed into a U-shape by a forming means in order from the staple at the front end. After that, the spelling is performed by being driven by a driver toward the material to be sewn.
