Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a copying machine, and more particularly to a paper ejection and conveyance path of a copying machine equipped with a post-processing device such as a stapler.

[Prior art]

The conventional copying machine 1 shown in FIG. 1 has an automatic document feeder 3 installed above the main body 2, and a stapler 4a and sorter 4 installed on the sides of the main body 2. The original 5 is placed on the original placing table 6 of the automatic document feeder 3 as shown in FIG.
As shown in a), the left side edges of the originals 5 are set together, and the stacked originals 5 are taken out one after another starting from the lowest one, and are inverted and set on the platen 7. therefore,
The document 5 on the platen 7 has the binding position 5a in FIG. 2 (1))
As shown, it 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 to the photoreceptor 10
The image is transferred as shown in FIG. 2(C). 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(d)) and is discharged onto the catch tray 11 or the bin 12 of the sorter 4. 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, in FIG. 1, the reference numeral 13 is a conveyance path switching device, and this device 1
3, it is selected whether the paper 9 conveyed from the photoreceptor 10 is to be stored on the catch tray 11 or on the bin 12 of the sorter 4. Also code] 4
is a transport, and the transport is sorter 4
The sheets 9 transported to the bin 12 are sequentially distributed to each bin 12 according to the set number of copies.

When the sheets 9 are conveyed to the sorter 4, the sheets 9 on each bin J2 are transferred to the stapler 4 after the copying of all originals is completed.
A is sequentially bound by a.

Incidentally, such a copying machine 1 may be used with the automatic document feeder 3 removed. In that case, the operator usually sets the original 5 directly on the platen 7 in order from the first page and copies it. As is clear from the copying process described above, the copied paper 9 is placed on the bin 12 of the sorter 4 with the copy side facing up, and the order of the pages is reversed. , the stapler 4a cannot be used as it is.

Therefore, when performing manual operation on such a copying machine, the copied sheets 9 are placed on the bins 12 of the sorter 4 with the copy side facing down and the binding position 9a located on the stapler 4a side. It becomes necessary to change the posture of the paper 9 so that it is placed thereon.

Now, when using the copying machine 1 and trying to discharge the copied paper 9 onto the bin 12 of the sorter 4 in a position that satisfies manual operation, the photosensitive member The paper 9 must be rotated 180 degrees and reversed using a turntable-type paper attitude changing device, an abutting-type paper attitude changing device, etc., which will be described later.

However, the above-mentioned turntable-type sheet attitude changing device has a configuration in which the sheet 9 being conveyed is placed on the -B turntable, rotated 180 degrees on the turntable, and then the sheet 9 is transferred to the discharge side conveyor belt. Since this method is adopted, there is a possibility that the conveyance operation of the paper 9 will be discontinuous, and it may not be possible to cope with the case where the paper 9 is continuously copied.
In addition, the paper 9 on the turntable must be rotated 180 degrees accurately, the turntable must be operated after confirming that the paper 9 has been placed on the turntable, and the paper 9 must be rotated 180 degrees before being discharged. It is necessary to take into account the necessity of a means for delivering the paper 9 to the belt, the necessity of means for intermittent operation of the turntable, etc., and therefore the apparatus becomes complicated. In addition, the paper position changing device using the butting method moves the paper 9 into the case by rolling the paper 9 into the case.
JL is added, the paper is ejected out of the case again, and the paper 9 is thereby reversed.
As with the turntable-type sheet position changing device described above, the conveyance operation of the sheet 9 becomes discontinuous, and there is a risk that it will not be possible to cope with the case where the sheets 9 are continuously copied. This method may not be applicable to sheets 9 of different sizes.

Therefore, if such a turntable-type paper posture change device and a butt-type paper posture change device are installed in the paper ejection and conveyance path of the copier 1, not only will the internal mechanism of the device become complicated; , it is not possible to speed up the copying process.

[Purpose of the invention]

SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to provide a copying machine that has a simple structure, can change the orientation of paper, and can speed up copying operations.

[Structure of the invention]

In order to achieve such an object, the present invention uses a paper posture changing device formed by winding one endless belt around a roll so that a part of the belt meets a roll, and a conveying path equipped with this device. A branch is installed in parallel to the paper output conveyance path of the copying machine, and a conveyance path switching device is installed at the branch point, so that the copied sheets conveyed from the photoconductor are bound in the same direction and are reversed. It is designed so that it can be discharged in two postures.

〔Example〕

The present invention will be described below with reference to embodiments shown in the drawings. 3 and 4 show a paper posture changing device 15 applied to the copying machine of the present invention. This paper posture changing device 15 moves one endless belt 16 to rolls 17a to 171! as shown in FIG. Wrap it around, part of that belt 1
6a, H5b as Ll −/L/17 a, 17 g
and are separated again by rolls 17f and 1711. Meanwhile, part of the belt 16a, i6b
is rotated 90 degrees and reversed by roll 171),
It is then reversed by rolls 17C and 17d, further rotated 90 degrees and reversed by roll 1.7e, and reaches rolls 17f and 17h. In addition, the above belt 1
6 is driven by at least one of the rolls 1.7a-171.

Therefore, as shown in FIG. 4, the paper 9 inserted from one end of the left side of the belt 16 in the attitude shown in FIG. 5(a) is
It is rotated by 90 degrees and reversed by the roll 17b, changed to the posture shown in FIG.
FIG. 6 shows such a sheet. A copying machine 21 according to the present invention is shown in which a posture change device 15 is incorporated in the conveyance path of paper 9. This copying machine 21
In this case, a conveyance path 18a equipped with a paper posture changing device 15 is arranged parallel to and branched from the ejection conveyance path 18 for the copied paper 9, and a conveyance path switching device 19 is installed at the branch point. In addition,
In Fig. 6, the same symbols as in Fig. 1 are given.
Showing the same element.

This copying machine 21 uses paper 9 that is copied as follows.
is discharged and conveyed onto the catch tray 11 or the bin 12 of the sorter 4. When the automatic document feeder 3 is installed in the copying machine 21, and the documents 5 placed on the document table 6 are sequentially taken out from the lowest one, and then reversed and set on the platen 7, , the conveyance path switching device 19 is not activated, that is, the paper 9 is discharged onto the catch tray 11 or the bin 12 of the sorter 4 without passing through the paper posture changing device 15. As in the case of the copying machine 1 shown in FIG.
1 or on the bin 12 of the sorter 4.

Therefore, the sheets 9 loaded on the bin 12 of the sorter 4
are stapled as they are by the stapler 4a. In addition, when the automatic document feeder 3 is removed from the copying machine 21 and the documents 5 are set on the platen 7 in order from the first page to perform copying, the conveyance path switching device 19 is activated and the paper 9 is moved immediately. is discharged onto the catch tray J1 or the bin 12 of the sorter 4 via the paper posture changing device 15. The sheet 9 ejected in this way is changed to the posture shown in FIG. They are loaded on the catch tray 11 or the bins 12 of the sorter 4 at the front of the row. Therefore, the sheets 9 stacked on the bin 12 of the sorter 4 are stapled as they are by the stapler 4a.

However, in this case, the sheets 9 are stacked on the catch tray 11 with the copy side facing down. If the operator wishes to copy while checking the copying state of the paper 9 discharged onto the catch tray 11, the conveyance path switching device 19 need not be activated. However, in this case,
The page order of the sheets 9 on the catch tray 11 is reversed.

In the above embodiment, in order to make it easier to understand the paper posture changing device J5, the height direction in FIGS. 3 and 4 is enlarged, 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 17C917d, roll 17j, 1
7a, roll 17r, ryi, roll 17h, ], 7 and roll 1.7j? , 17g is 1 with an appropriate diameter
can be replaced by each role. In addition, in the embodiment, the rolls 17C, ], 7d are installed in the front in FIG. However, the ejection posture of the paper 9 does not change at all. Further, the conveyance path switching device 19 in the above embodiment may be operated in conjunction with the attachment/detachment (or use/non-use) of the automatic document feeder 3, or may be operated independently without being coupled with the automatic document feeder 3. You can also strain it. These actuation mechanisms may be purely mechanical using link mechanisms or electrical using electromagnets.

〔Effect of the invention〕

As described above, the copying machine according to the present invention changes the posture of the copied paper along the ejection transport path l on the same plane and in the same straight line. The space is small, so it can be made compact, and since the sheets being conveyed can be continuously discharged without stopping, it is possible to increase the speed.
