Next, the operation will be described with reference to FIGS. 1, 2, and 3. Note that FIG. 3 shows a flowchart of the mode select key processing. That is, in one embodiment of the present invention, for example, in the case of continuously copying a document bundle having a front cover, a middle cover, and a back cover, it is desired to correspond to a specific manuscript of the front cover, the middle cover, and the back cover, respectively. ) If you want to make a copy on any type of transfer paper, it is determined in advance that only the transfer paper of the desired paper type will be fed from the first paper feed cassette 11, and this setting is set to the ADF of the keyboard.
When the ADF mode and the paper feed port selection mode are selected by inputting the mode key, the paper feed port selection mode key, and the numeric keypad operation, copying is performed corresponding to specific originals of the front cover, middle cover, and back cover, respectively. The transfer paper of a desired (arbitrary) paper type is operated so as to be fed from the first paper feed cassette 11.

In addition, in the paper feed port selection mode, if you want to make a copy on a transfer paper of an arbitrary paper type corresponding to only one or two originals of the front cover, the middle cover, and the back cover, this transfer paper is fed. The paper feed cassette for paper does not need to be limited to a specific paper feed cassette as described above, and each paper feed cassette can be individually selected and set when the paper feed port selection mode is set.
It is also possible to specify and feed a transfer paper of an arbitrary paper type to be copied. Also, if you want to make copies on different types of transfer paper corresponding to only one or two cover originals of the front cover, the middle cover, and the back cover, select each paper feed cassette. It is also possible to individually specify and feed the transfer paper of an arbitrary paper type.

Further, for example, in FIG. 2, each original in the original stack including the original D1 on the front cover, the original Dx on the x-th cover, and the original Dn on the n-th back cover is referred to the keyboard. A case where continuous copying is performed by a series of operations of the above keys will be described. In this case, the second sheet of the original stack (second page)
The transfer paper to be copied corresponding to each of the (n-1) th document except the xth document (xth page) Dx is
By a series of operations with the respective keys of the keyboard, the operation is automatically determined in accordance with the preset size or magnification of each original, and the paper is fed from a paper feeding cassette other than the first paper feeding cassette 11. Is configured.

Here, for example, on a thick transfer sheet accommodated in the first paper feed cassette 11 corresponding to the original D1 of the first page and the original Dn of the nth page, which are specific originals in the bundle of originals, page x Eye manuscript Dx
Corresponding to the blue transfer paper stored in the second paper feed cassette 12 and the white transfer paper stored in the third paper feed cassette 13 corresponding to normal originals other than the specific original. An operation method for making a series of copies when the respective copies are desired will be described. First, the first paper feed cassette 11 is selected / designated by depressing the paper feed port selection mode key of the keyboard, and the first page document D1 and the nth page document Dn are the document pages. The information (in this case, the first page and the nth page) is set by the operation of the ten-key pad and the enter is made. Then, the second paper feed cassette 12 is selected and designated by the same operation as the keyboard operation described above, and the information of page x is set by pressing the ten keys to enter.

The image forming apparatus to which the present invention is applied by performing the input operation for making such a series of copies with the keyboard is the first page document D1 and the nth page document in the document stack.
A blue transfer paper stored in the second paper feed cassette 12 corresponding to the document Dx of the x-th page is copied by copying the thick paper transfer paper stored in the first paper feed cassette 11 corresponding to Dn. Then, the copy can be performed with the white transfer paper stored in the third paper feed cassette 13 corresponding to the normal originals other than the specific original.

Therefore, by the first input operation of the keyboard for making a series of copying in this manner, automatically and continuously,
Copying can be performed by feeding transfer papers of different paper types, that is, transfer papers of a desired (arbitrary) type, which have the same size and correspond to specific pages in the original bundle.

Furthermore, the information to be copied by the paper feed (white transfer paper) stored in the third paper feed cassette 13 corresponding to the normal originals other than the cover original, which is the specific original, is the paper feed port selection. Since the information is fetched by the control means as the information in the previous step of selecting the mode, if the magnification of copying is designated in the previous step, it is possible to execute the feeding of the transfer paper corresponding thereto.

The present invention can be applied not only to ADF but also to RDF such as when using an automatic document feeder for continuously copying while circulating each document.

Next, in step 123, when the numeric keypad input does not exceed 50 pages, the process proceeds to step 124 and sequentially from the original page number memory DBPAG (page number input counter CTPAG) and from the second paper feed port (second paper feed cassette 12). The number of pages of the document corresponding to the transfer paper of the paper type to be fed is stored, and subsequently, in step 125, the page number input counter CTPAG is incremented. And step 1
When the page number input counter CTPAG exceeds 10 pages in 26, the data entry end flag is turned on in step 127, and the process returns to the main flow. Meanwhile, step
If the page number input counter CTPAG does not exceed 10 pages in 126, the process returns to step 112.

If the N-th paper feed port is selected in step 114, the number of pages of the original corresponding to the transfer paper of the paper type desired to be fed from the N-th paper feed port is input using the ten keys in step 128, and then step If the numeric keypad input value does not exceed 50 in step 129, in step 130 the original page number memory DBPAG (page number input counter
The number of pages of the original corresponding to the transfer paper of the paper type desired to be fed from the Nth feed port is stored sequentially from CTPAG). Then, in step 131, the page number input counter CTPAG is incremented, and when the page number input counter CTPAG exceeds 10 pages in step 132, the data entry end flag is turned on in step 127 and the process returns to the main flow. If the page number input counter CTPAG does not exceed 10 pages in step 132, the process returns to step 112.
