As shown in FIGS. 1 to 3, the copying machine according to the present embodiment is a set of two in which copying machines (transfer sheets) of the same size are accommodated in the copying machine main body 1 with the directions thereof being different by 90 °. Paper feed cassettes 2a and 2b and paper discharge tray 3
And an automatic document circulation device (RDH) 4.
The first control unit 5 for controlling the copying machine body 1 includes an image forming unit 6, an image processing unit 7, a paper feed cassette changing unit 8, a second control unit 9 for controlling the automatic document circulating device 4, and The operation unit 10 and the like are connected. The second control unit 9 has
A document detection sensor 11, a transport motor 12 for transporting a document, etc. are connected. Further, the operation unit 10 includes a discharge mode selection unit 13 and a discharge mode selection unit 13 for switching the processing mode between a sorting mode for sorting the image-formed sheets and a non-sort mode for not sorting the sheets. Mode storage unit 1 for storing the mode selected by
4, a copy number input unit 15 for presetting a desired copy number, a preset copy number storage means 16 for storing the copy number set by the copy number input unit 15, a copy number counter 17 for counting the copy number, a print button 18, etc. It is equipped. A processing procedure in the copying machine having the above-described hardware structure will be described below with reference to FIGS. In the figure, S0, S1, ... Indicate processing steps.

When sorting a plurality of copies of the transfer paper for each bundle in the image forming process, first, a process (S0) related to the initialization of the copy number counter 17 is performed, and then the discharge mode selection unit 13 sorts the sheets. Mode is selected (S
1, S2), and on condition that the document stack is placed on the automatic document circulation device 4 (S3), the sort mode is stored in the mode storage unit 14 (S4). In the case of the non-sort mode, this mode is stored in the mode storage unit 14 in S5. Subsequently, in S6, when the desired number of transfer copies is set by the copy input unit 15, this value is stored in the preset copy storage means 16 (S).
7). When the print button 18 is operated under the above conditions (S8), the subsequent processing shifts to the sort mode. If the number of copies is not set in S6, only one copy is required for the image forming process, so 1 is set as the preset copy (S9, S1).
0). Further, when it is determined in S11 that the document is not placed on the automatic document circulation device 4, a normal image forming process known from the related art is executed (S12 to S).
16, see FIG. 7). Further, if it is determined in S17 that the subsequent processing is the non-sort mode, S
Conventionally well-known processing is performed as shown in 18 to S24 (see FIG. 6). In the sort mode (see FIG. 5), the document is fed from the document stack on the automatic document circulating device 4 toward the upper surface of the contact glass (S25),
For example, the paper feed cassette 2a (the paper feed cassette 2a is
The sheet is fed from the state that the sheet is accommodated in a state where the longitudinal direction is parallel to the sheet conveying direction) (S26). At the time of the first image forming processing, the number of copies is 0 (S27
a) The image forming process is carried out according to a conventionally known procedure (the same applies when the value of the copy number counter 17 is an even number) (S28).
It is discharged upward (S29). The above-described series of processing is executed for all the originals corresponding to the number of copies for the first time (S30), and after the completion, 1 is added to the value of the copy number counter 17 and the value becomes an odd number ( S3
1). Then, in S32, the value of the copy number counter 17 is compared with the transfer number stored in the preset number storage means 16, and if these values are not equal, the direction of the paper is changed by 90 ° in S33. The paper feed cassette 2b to be accommodated by mistake is selected.

Then, the subsequent processing is the same as S25,
The process proceeds to S26, but in this case, it is determined that the value of the copy counter 17 is an odd number (S27).
b), the read data of the original document is subjected to 90 ° coordinate conversion every time the image forming process is performed (S34). The above-described processing is performed on all the originals, and the paper after the image formation is discharged onto the paper discharge tray 3. Then, the above S
At 31, the copy counter 17 is incremented by 1. Then, these series of processes are sequentially repeated until the value of the copy number counter 17 and the value stored in the preset number storage means 16 match. That is, in the copying machine, each bundle of sheets on which image formation processing is performed corresponding to the odd-numbered transfer number and the even-numbered transfer number are alternately 90 degrees different in direction, and on the discharge tray 3. It is discharged so that it is piled up. As a result, a plurality of sets of sheets after image formation can be easily sorted into each bundle without using a sorter such as a sorter as in the case of the conventional apparatus. In the above embodiment, the case where the image of the original is read and processed for each image formation corresponding to each sheet bundle has been described. However, the image of the original is read and stored in advance, and the image corresponding to each sheet bundle is stored. An embodiment in which processing is performed based on the stored read data for each formation will be described below with reference to FIGS. 8 and 9.
In the copying machine according to this embodiment, the former part (see FIG. 4) in the series of processing procedures is the same as that of the copying machine described above, and therefore the description thereof is omitted and the sorting is a characteristic part. Only the modes will be described in detail. First, S
At 35, the value of the counter N indicating the number and the order of the originals is reset, and the originals are fed from the original stack on the automatic original circulating device 4 toward the upper surface of the contact glass (S36). The image of the original fed as described above is read by the reading device, the content is stored in the memory corresponding to the Nth (S37), and the paper fed from the paper feed cassette 2a ( For S38, image forming processing is performed based on this image data (S3).
9). Then, the paper after the image formation is the above-mentioned paper discharge tray 3
The document is discharged to the upper side (S40), and the document on the contact glass is returned to the automatic document circulating device 4 (S4).
1).

The above series of processing is continued while updating the value of the counter N (S43) until it is judged that all the originals are finished (S42). Above S42
When it is determined that the image forming processing for all the originals is completed in step S1, 1 is added to the copy number counter 17 (S44), and the value of the counter N is set in the memory as the number of originals (S45). . After that, the value of the counter N is reset (S46),
The paper feed cassette 2b is selected (S47). And S
At 48, it is determined whether the value of the copy counter 17 is an odd number. Here, since the paper feed cassette 2b is selected in S47, the image data stored in the memory corresponding to the Nth is 90 ° coordinate-converted (S49) and fed from the paper feed cassette 2b. An image forming process is performed on the received paper (S50) (S51), and the paper after the image formation is discharged onto the paper discharge tray 3 (S52). In this case, the sheets are discharged while being stacked on the sheet bundle in a state where the direction thereof is different from that of the sheet bundle subjected to the image forming processing by 90 ° corresponding to the number of the previous transfer. After the paper is discharged in S52,
One is added to the value of the counter N (S53), and the series of processes described above is continued until it is determined that this value becomes equal to the number of originals (S54). After that, 1 is added to the copy number counter 17 in S55, and the series of processes is performed in S56.
Is repeated until the value stored in the preset copy number storage means 16 becomes equal. In this case, each time the copy number counter 17 is incremented by 1, the paper feed cassettes 2a and 2b are switched alternately, and depending on whether the value of the copy number counter 17 is an odd number (S48). The processing in S49 and the step of reading and processing the image data without coordinate conversion (S57) are alternately and repeatedly selected. As a result, the bundles of sheets on which the image formation processing has been performed corresponding to the odd-numbered transfer number and the even-numbered transfer number, respectively, are alternately stacked in the discharge tray 3 with their directions shifted by 90 °. To be done. By reading and storing all the images of the original document in advance as described above, the automatic document circulation device 4 according to the above-described embodiment can be omitted and the original document can be handled by manual feeding. Further, instead of the automatic document circulating device 4, an automatic document feeding device can be applied.

[0010]

Since the digital image forming apparatus according to the present invention is configured as described above, it is possible to transfer a plurality of copies of the transfer paper after image formation without using a sorting device such as a sorter as in the case of the conventional apparatus. Can be easily sorted for each bundle.
