Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The first invention is a stapler having a function of sorting sheet materials discharged from an image forming apparatus such as a copying machine, a printer or a facsimile, and binding the sorted sheet material bundle. Regarding sorter.

A second invention relates to an image forming apparatus provided with the staple sorter.

[0003]

2. Description of the Related Art Generally, a built-in stapler provided in a staple sorter has a binding capacity of about 20 to 50 sheets because it is necessary to bind two sheet materials. This is related to the length of the stapling foot. This is because, for example, when binding a small number of sheet materials with a stapler having a binding capacity of about 100 sheets, the legs of the binding needle are too long.

If a built-in stapler having a binding capacity of about 100 sheets is required, a cutting mechanism for cutting the legs of the binding needle short when binding a small number of sheet materials, or 1 It is necessary to use a stitcher type stapler in which a wire of a book is formed into a needle shape and then hammered.

However, this must be done 1
20 to 5 staplers having a binding capacity of about 00 sheets
Since the size of the stapler is too large to be compared with a stapler having a binding capacity of about 0 sheets, as shown in FIGS. 5 and 6, the size of the staple sorter main body 1B (the portion shown by the dotted line) is 20 to 50 sheets. The size is significantly larger than the size of the staple sorter main body 1A (the portion shown by the solid line) when a stapler having a binding capacity of about one sheet is provided, and
There was a problem that it became expensive.

5 and 6, reference numeral 2 is a stapler provided in the staple sorter body 1A and having a binding capacity of about 20 to 50 sheets, and reference numeral 3 is about 100 sheets provided in the staple sorter body 1B. It is a stapler having a binding capacity of.

Since the staplers 2 and 3 are attached to the staple sorter main bodies 1A and 1B so as to be movable in the direction of arrow A, the staple sorter main bodies 1A and 1B are attached.
The widths B1 and B2 and the lengths L1 and L2 of the stapler 2 and 3 are
It becomes the size that can be moved.

In addition, each bin 5 of the mobile bin unit 5
Among the 1 to 5-10, the space between the bin in which the sheet material is ejected by the ejection roller pair 6 and the bin above it is widened to the interval l1 that enables the ejection of the sheet material, and the staplers 2, 3
The space between the bins for stacking the sheet material bundle to be bound by and the upper and lower bins is widened to intervals l2 and l3 that allow the staplers 2 and 3 to move. These intervals l1,
The heights H1 and H2 of the staple sorter main bodies 1A and 1B are determined in consideration of the sizes of l2 and l3 and the intervals between the bins 5-1 to 5-10 on which a predetermined number of sheet material bundles are stacked.

The staple sorter main body 1B having a stapler having a binding capacity of about 100 sheets has 20 sheets or more.
Compared with the staple sorter main body 1A including the stapler 2 having a binding capacity of about 50 sheets, all of the width, length and height are significantly increased (B2> B1, L2> L).
1, H2> H1).

As described above, the staple sorter 1 in which the staple sorter main body 1B is enlarged by providing the stapler 3 having a binding capacity of about 100 sheets is adopted when the image forming apparatus 7 is a high-speed and large-sized machine. However, if the image forming apparatus 7 is a medium speed machine or less or a medium size machine or less, the balance (size, cost, etc.) with the image forming apparatus 7 cannot be taken, and therefore it should be adopted. Is difficult.

Therefore, in the conventional staple sorter, when binding a sheet material bundle of about 100 sheets, it is divided into a plurality of sheet material bundles of 50 sheets or less, and each of these sheet material bundles is bound to about 20 to 50 sheets. A staple 2 having a capacity is used for binding, or a bundle of about 100 sheets is bound by a dedicated binding device having a binding capacity of about 100 sheets and different from the staple sorter.

In this case, the staple 2 is driven only when the split binding is selected to bind each of the divided sheet material bundles. Further, when a bundle of about 100 sheets of sorted material is integrally bound by a dedicated binding device, split binding is not selected.

[0013]

However, when adopting a method of integrally binding a bundle of about 100 sheets of sorted sheet materials together by a dedicated binding device like the staple sorter of the above-mentioned conventional example, each staple sorter 1 is used. Bins 5-1 to 5-10
Remove the unbound sheet material bundle from the sheet, carry it by hand to a dedicated binding device installed in a place apart from the staple sorter 1, and bind each sheet material bundle with the dedicated binding device. Therefore, the sheet material bundles that are aligned at the time of sorting tend to come apart during the transportation of the sheet material bundles from the staple sorter 1 to the dedicated binding device, and the sheet material bundles can be handled by hand when binding with the dedicated binding device. I had to rearrange them.

Therefore, the first invention is made in view of the above-mentioned circumstances, and a large bundle of sheet materials sorted in excess of the binding capacity of the stapler incorporated in the staple sorter main body can be bound together. An object of the present invention is to provide a staple sorter that has a capacity binding function and does not increase the size of the staple sorter main body due to the large capacity binding function.

The second aspect of the invention is made in view of the above-mentioned circumstances, and a large bundle of sheet materials sorted in excess of the binding capacity of the stapler built in the staple sorter body can be bound together. It has a capacity binding function, and
An object of the present invention is to provide an image forming apparatus in which the main body of the image forming apparatus does not become large due to having the large capacity binding function.
