Abstract

PURPOSE:To change the attitude of a sheet under transport, continuously by setting parts of an endless belt on rolls in such a way as meeting each other, by allowing a sheet loaded from one of the ends of this meeting point to be rotated and inverted together with said belt, and by exhausting from the other end. CONSTITUTION:In a sheet attitude change device 15, an endless belt 16 is set on rolles 17a-17l, and parts 16a, 16b of this belt are met by the rolls 17a, 17g and separated by the ones 17f, 17h. Meantime, these parts of the belt are rotated 90 deg. and inverted by the roll 17b, inverted again by the rolls 17c, 17d, and further rotated and inverted by the roll 17e to be then sent to the rolls 17f, 17h. A sheet 9 inserted from one of the ends of the meeting parts 16a, 16b of the belt in said arrangement will be rotated 90 deg. and inverted by the rolls 17b, inverted by the 17c, 17d, and further rotated 90 deg. and inverted by the roll 17c to be exhausted from the other end while taking the changed attitude.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper posture changing device, and more specifically,
The present invention relates to a device that is installed within a paper conveyance path and changes the posture of the paper within the path.

Particularly, in a copying machine coupled with a sorter with a stapler as shown in FIG. 1, the ejection posture of the copied sheets is important.

This copying machine 1 has an automatic document feeder 3 installed above the main body 2.
A sorter 4 with a stapler 4a is installed on the side of the main body 2 of the apparatus. The originals 5 are set on the W stacking table 6 of the automatic document feeder 3, with the left side edges of the originals brought together as shown in FIG. They are taken out one by one, turned over, and set on the platen 7. Therefore, the binding position 5a of the document 5 on the platen 7 is located on the right side.

If you perform a copying operation with the original set in this way,
The paper 9 conveyed from one of the feeders 8 is transferred by the g-light body 10 as shown in FIG. 2(b). Therefore, the binding position 9a of the paper 9 in this state is located on the right side.

The paper 9 copied in this way remains in the same position (
(see FIG. 2(C)) and is discharged onto the catch tray 11 or the bin n of the sorter 4. Note that the document 5 on the platen 7 is then discharged onto the document discharge tray 6', and at the same time, the next document 5 is set on the platen 7. In addition, the first
In the figure, reference numeral 13 denotes a conveyance path switching device, and by operating this device 13, the paper 9 conveyed from the photoreceptor 10 is stored on the catch tray 11 or on the bin 12 of the sorter 4. Choose whether to Further, reference numeral 14 denotes a transport, and the transport 14 sequentially distributes the sheets 9 conveyed to the sorter 4 to each bin 12 according to the set number of copies.

When the sheets 9 are conveyed to the sorter 4, after the copying is completed, the sheets 9 on each bin 12 are sequentially stapled by the stapler 4a.

Incidentally, in such a copying machine 1, the automatic document feeder 3 may not be used. In this case, the operator usually sets the original 5 directly on the platen 7 in order from page 1 and copies it. Then, as is clear from the copying process described above, the copied paper 9 is placed on the sorter 4 with the copy side facing up.
Since the pages are stacked on the paper 712 and the order of the pages is reversed, the Horakis binding device 4a cannot be used until this point t.

Therefore, in such a copying machine 1, when performing a manual operation, the copied sheets 9 are placed in the bins 12 of the sorter 4 with the copy side facing down and the binding position 9a positioned on the stapler 4a side. The posture of the paper 9 must be changed so that it is placed on top of the paper 9.

The present invention provides a paper posture changing device that satisfies such requirements, and its features are as follows:
An endless belt is used, and the belt is wound around a roll so that it meets each other at some parts, and the paper inserted from one end of the meeting part is rotated together with the belt, reversed, and then discharged from the other end of the meeting part. ing.

The present invention will be described below with reference to embodiments shown in the drawings. FIGS. 3 and 4 show a paper posture changing device 1 according to the present invention.
5 is shown. This paper posture changing device 15 moves one endless belt 16 from roll 17a to roll 17a as shown in FIG.
177, parts 16a and 16b of the belt are brought together by rolls 17a and 17g, and roll 1
It was separated again at 7f and 17h.

Meanwhile, parts of the belt 16a, 16bij:, roll 1
7b and then rotated 90 degrees and reversed by roll 1
Reversed by 7C and 17d, further roll 17
Rotated 90 degrees and reversed by e, rolls 17f, 1
It lasts until 7 hours. Note that the belt 16 is attached to each roll 1.
It is driven by at least one of 7a to 17i1.

Therefore, as shown in FIG. 4, the paper 9 inserted from one end of the left side meeting in the attitude shown in FIG.
It is rotated and reversed by 90 degrees and changed to the posture shown in FIG. 5(b), further reversed by rolls 17c and 17dlC and changed to the posture shown in FIG. Rotated and reversed to show Figure 5 (
It is ejected in the position shown in d).

FIG. 6 shows a copying machine 21 in which such a sheet posture changing device 15 is incorporated in the sheet 9 transport path. In this copying machine 21, a conveyance path switching device 18 is installed in front of the paper posture changing device 15. This conveyance path switching device 18 transports the paper 9 through the bypass path 19 when the automatic document feeder 3 is used, and stores the paper 9 into the sorter 4 without using the automatic document feeder 3. In this case, it can be selected as appropriate to transport the paper through the paper posture changing device 15.

Therefore, in this copying machine 21, the automatic document feeder 3
When using the automatic document feeder 3, the copied paper 9 is discharged onto the catch tray 11 or the bin 12 of the sorter 4 in exactly the same posture as the copying machine 1 shown in FIG. When the document 5 is set on the platen 7 in order from the first page without being used, the paper 9 transferred by the photoreceptor 10 (see FIG. 5(a)) is moved to the fifth page by the paper posture changing device 15. The posture is changed to that shown in figure (d),
In this state, it is loaded onto the bins 12 of the sorter 4. In this way, the sheets 9 loaded on the bin 12 of the sorter 4 are placed with their copy side down and the binding position 9a facing the stapler 4a, so they can be left in the stapler 4a. 4a can be activated.

In the above embodiment, the paper posture changing device 15 is shown enlarged in the height direction in FIGS. 3 and 4 in order to make it easier to understand, but in reality, the thickness of the belt 16 is taken into account. Since only one layer is required, it can be made extremely thin.

In that case, roll 17C717d, o- to 17j
, 17a, o-le 17f, 17i, .

- The rolls 17h and 17 and the rolls 171 and 1M can each be replaced with one roll having an appropriate diameter. Further, in the embodiment, the rolls 17C and 17d are installed in the front in FIG. There is no change in the ejection position.

As described above, the paper posture changing device according to the present invention has t
Since the paper position can be changed on the same plane and in the same straight line, the installation space for the device is small, and since the paper position can be changed without stopping the paper being conveyed, it is possible to change the paper position continuously. This is extremely advantageous in changing the posture of the paper being conveyed.
