It will be supplied from the copying machine after the next gate 33 is stopped.

3 and 4 show the entire apparatus of the present invention, and as can be seen from these figures, a processing device 11 is connected to a copying machine 10. The processing device 11 is provided with a rotator 12 constituted by a direction changing device 20 and a binding device 30, which are integrally configured.

As shown in detail in FIG. 4, the above-mentioned processing device 11 of the present invention connects the paper inlet of the processing device 11 to the copy output port of the main body of the copying machine, so that copies introduced into the processing device are can be arbitrarily distributed via the fingers 14 into a paper conveyance path 16 for conveying toward the binding machine and a bypass conveyance path 15 for directly discharging to a discharge tray 17.

The paper transport path 16 of the rotator 12 provided in the processing device 11 is provided with a direction changing device 20 for changing the direction of the paper. As will be described below with respect to the embodiment shown in the figures, a device is provided which allows the direction of paper transport to be changed by 90 DEG.

Then, when the paper ejected from the copying machine 1 passes through the paper transport path 16, changes its direction, and is deposited on the belt 32 of the binding machine 30, the paper alignment operation shown in FIG. 1 is performed. , the paper stack is aligned,
A stapling operation is performed by the stapler 5. Then, after being formed into a bound product, it is nipped by an ejector roller 40 and a nip roller 41, and is ejected onto the ejection tray 17a.

The direction changing device 20 provided on the rotator 12 has a configuration as shown in FIG. 5. Direction changing device 2 shown in this example

Note that, following the direction changing mechanism using the disk and belt device, a side guide 25 is provided in order to register the paper, and the paper 1a whose direction has been changed is guided along the side guide 25. Then, the paper conveyance path 17 of the rotator 12
Inside, the paper can be transported to the binding machine 30, which is the next processing device.

As mentioned above, the reason why the direction changing device 20 of the present invention is required is that a document is set horizontally on the platen of a copying machine, and the document is scanned in the width direction, and the scanning time of the image reading device is There is a tendency for more and more devices to be used that are configured to shorten the length, increase the speed of copying, and improve the efficiency of copying.

In the case of the above-mentioned copying machine, the copies are ejected in the width direction, and it is not possible to make copies in such a copying machine in that state. It is required to change the paper transport direction in the paper transport path from the machine to the binding machine. Therefore, by using a direction changing device having the mechanism as described above, it can be easily applied to a binding machine.

In the above-mentioned device of the present invention, any mechanism can be used as the direction changing device, and furthermore, when a mixture of large and small size sheets is ejected from the copying machine, ,

In other words, the example shown in FIG. 7 is an example in which a stack of sheets is stapled at one location, and the stapler 5 is set at a fixed position, transported by the set transport belt, and aligned. The stapler 5 can automatically perform the stapling work on the items that have been worked on.

In the embodiment shown in FIG. 8, the stapler 4 is provided at a fixed position, but the stack of sheets conveyed by the set transport belt is stopped at two stapling positions, and the stapler 4 is fixed at a fixed position. Therefore, the stapling position is set by the gate of the belt, and stapling is performed by the staple pin. In both of these two embodiments, the paper 1 is ejected from the copying machine 10 horizontally, the paper is direction-changed by the direction changing device 20, and is deposited on the set transport belt to form the paper bundle 2. After arranging the sheets to be formed, the stapler 5 performs the stapling operation.

Therefore, when using the binding machine 30 of the present invention, it becomes possible to drive staple pins into arbitrary positions on the bound work, thereby maximizing the performance of the copying machine. This will allow you to create a bound item.

(Effects of the invention) Since the post-processing device of the present invention, such as a copying machine, has the above-mentioned configuration, single and double stapling modes can be freely set using one stapler. It becomes possible to simplify the configuration of the binding machine. Furthermore, since the device of the present invention can carry out all of the paper conveyance, paper alignment, positioning, and stapling operations using the set transport belt,
The entire device can be configured compactly, and the processing device can be downsized.

The belt device of the present invention is tilted so that the leading end on the ejection side is lower, so the leading end of the copy that is introduced into the binding machine can be easily positioned, and it can be placed on both sides of the belt. Paper alignment work can be easily performed simply by applying a tapping action using the paper alignment means. Furthermore, since the set transport belt of the present invention has an endless structure, the work can be performed continuously according to the flow of paper, and the work performance can be improved.
