Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention allows the staple cartridge to be loaded inside from the exit of the staple cartridge when it is installed in the stapler. A staple cartridge that prevents sheet staples stored in layers from falling out easily. Regarding.

0002

[Prior art]

For staple cartridges containing stacked sheet staples, the sheet The tab-shaped staples are inserted into the stapler from the outlet at the lower end of the front wall in order, starting from the lowest layer. It is sent to the staple forming and driving section by a feeding device such as an endless belt. Therefore, the When the staple cartridge is installed in the stapler, the lowermost sheet-like staple The loop can be fed from the outlet by an endless belt. That is, the bottom Means are provided to prevent the sheet staples of the layer from passing through the outlet. The structure allows the bottom layer of sheet staples to easily slip out of the staple cartridge. It is constructed. Therefore, when the cartridge is installed, it may come out from the cartridge ejection port. If the remaining sheet staples remain on the stapler feeder, Sheet staples that overlap or are stacked above the pull and the pusher device. Two sheet-like staples in the lower layer are ejected from the ejection port at the same time due to the pressing force of both. This may cause problems such as the outlet becoming clogged.

0003 In particular, staple cartridges are used in staplers built into copying machines, etc. Hold the staple cartridge in such a way that the ejection port for the sheet staples faces downward. There is a type that is attached to a staple cartridge, and in this case the staple cartridge Load the sheet staples in the lowest layer so that they can easily come out of the outlet. As a result, the incidence of the above-mentioned problems was even higher.

0004

[Problem that the idea aims to solve]

This invention solves the above-mentioned drawbacks, and when moving the staple cartridge, This prevents the bottom layer of sheet staples from slipping out from the discharge port of the cartridge. The object of the present invention is to provide a staple cartridge that can be used.

[0005]

[Means to solve the problem]

In order to solve the above problems, the staple cartridge of the present invention is an unformed staple cartridge. A staple that stores a large number of stacked sheet-like staples 2 formed by connecting pulls in a sheet-like manner. It is equipped with a pull storage section 3 and a discharge port 9 for supplying sheet-like staples at the bottom layer. In the staple cartridge 1 disposed at the lower end of the front wall 4 of the staple storage section, A pair of staple receivers for receiving both ends of the bottom layer sheet staple 2a The bottom part 6 of the staple storage part 3 is opened leaving the parts 7 and 7, and the uppermost sheet-shaped part is opened. A pusher device 10 for pressing sheet staples is arranged on the staples 2b. At the same time, from the back of the front wall 4 of the staple storage section, the sheet-like staples 2a of the lowest layer are A sheet-shaped staple extending from the lower surface to the outer surface of the rear wall 12 of the staple storage section 3 It is characterized by being provided with a piece 13 to prevent the staple 2 from being pulled out, and the staple storage portion The vicinity of the end of the extraction piece 13 located on the outer surface of the rear wall 12 is inserted into the staple cartridge 1. It is characterized by being attached to the rear wall 12 of.

【Example】

Embodiments of the present invention will be described below with reference to FIGS. 1 and 2. Figure 1 is based on the present invention. FIG. 2 is a perspective view of such a staple cartridge; It is a diagram of the attached stapler.

[0007] 1 is a staple cartridge according to the present invention, which stores sheet-like staples 2; A square storage section 3 in which the cartridge is stored and a front wall 4 located at the lower end of the storage section 3 and located closer to the cartridge 1. It is composed of a guide section 5 that guides the upper surface of the discharged sheet staple 2. Ru. At the bottom 6 of the cartridge 1, there is a staple that supports the lowest layer of sheet staples 2a. A table receiving section 7, 7 is provided at the lower end of each side wall 8, 8 of the storage section 3, and is provided at the front of the storage section. A staple outlet 9 is formed at the lower end of the wall 4. On the other hand, the top shelf of storage section 3 A pusher device 10 is arranged on the sheet-like staple 2b, and the pusher device 10 Due to the spring 11 of the sher device 10, the sheet staple 2 is always kept at the bottom of the storage section 3. A pressing force is applied toward 6.

[0008] From the back of the front wall 4 of the cartridge 1 to the bottom of the bottom sheet staple 2a, The sheet-like staples 2a in the lowest layer pass through the outer surface of the rear wall 12 of the storage section. A pull-out prevention piece 13 is extended to prevent The vicinity of the end of the extraction prevention piece 13 is temporarily fixed to the rear wall 12 with glue or the like. Extraction The prevention piece 13 is made of a thin flexible material such as paper, and has one end placed in the middle of the front wall 4. The other end is placed above the rear wall.

[0009] The staple cartridge 1 is installed in a holster vertically disposed in a copying machine (not shown). It is attached to the cartridge attachment part 15 of the cartridge 14. Cartridge mounting part 15 An endless belt 16 for staple feeding is stretched over the endless belt 16, and a cover is attached to the endless belt 16. The cartridge 1 is installed with the bottom 6 of the cartridge 1 inserted therein. As a result, the endless belt 16 The lowermost sheet staple 2a is pressed against the upper surface and the frictional force between the two The sheet-like staples 2a of the layer are attached to the staple forming part (not shown) of the stapler 14. sent to ).

0010

[Effect]

Direct the guide portion 5 of the staple cartridge 1 downward in order to attach it to the stapler 14. When the sheet-like staples 2 in the lowest layer of the cartridge storage section 3 are moved a moves to the discharge port 9 side, but the extraction prevention piece 13 is located in front of the discharge port 9. Therefore, the sheet staple 2a in the lowest layer cannot escape from the discharge port 9. . The cartridge 1 is inserted into the stapler 14 with the extraction prevention piece 13 extended. It is mounted on the cartridge mounting section 15. located on the rear wall 12 of the cartridge 1 after installation. Pull the end of the extraction prevention piece 13 along the rear wall 12 and remove it from the cartridge 1. Remove. As a result, the discharge port 9 is opened and the bottom layer of the staple sheet is removed. 2a comes into contact with the endless belt 16, and preparation for feeding is completed.

[0011] In addition, the end of the extraction prevention piece 13 temporarily fixed to the cartridge rear wall 12 is After wearing, it can be easily peeled off from the rear wall 12 and then removed from the cartridge.

0012

[Effect of the idea]

The cartridge ejection port is blocked by the pull-out prevention piece, so it is difficult to remove the cartridge. Sheet staples will no longer slip out of the ejection port during handling or installation. , it is possible to prevent sheet staples from slipping out or clogging the discharge port. After installation Staples can be easily removed by pulling the ends, making it easier to There will be no hindrance to the process.

[0013] In addition, the removal prevention piece is temporarily attached to the rear wall of the cartridge with glue, etc. The removal prevention piece does not fall off when handling the cartridge, and it is easy to remove it. The ends can be peeled off from the back wall.
