Reference numeral 15 is a DF that automatically feeds a plurality of sheet-like originals one by one to the original reading position and automatically discharges them again after the exposure process is completed. 16 is both sides or one side of the originals. Is a reading unit for converting the scanned image data into image data, and 17 is a printer for printing the image data on recording paper,
A HDD 18 stores the image data and the added number.
Is. Next, a description will be given of an embodiment in which a saddle-stitch type document is read by the image reading apparatus 10. Here, a saddle-stitch type manuscript refers to a manuscript with a saddle-stitched fastener removed such as a weekly magazine.

<Embodiment 1> Embodiment 1 is an embodiment in which the original including the first page and the last page of a double-sided spread original of the saddle stitch format is read in order. First, the staples of the saddle stitch are removed, and the document is set on the DF 15. At this time,
Place the originals so that you can read them in order, starting from the original with the first and last pages printed.

Next, an anti-booklet key (not shown) on the operation display unit 14 (a key for dividing a saddle-stitch-type original into pages and outputting it) is selected. Thereby,
The image reading device 10 starts reading a document. The document is fed from the DF 15 to the reading unit 16 and is read as image data by exposure, is inverted, and is similarly read on the back side and is discharged.

The read image data is divided into right and left so that it becomes a page unit and stored in the HDD 18. At this time, the CPU 11 adds numbers to the read image data in the order of page numbers of the document.

That is, the image data corresponding to the pages in ascending order from the first page of the document are numbered in ascending order, respectively, while the image data corresponding to the pages descending from the last page of the document are in descending order. Add a number. However, the number added in descending order is larger than the number added in ascending order. Note that the page number of the document and the number of the image data do not have to match, and the page order and the image data number may be in the same order.

After that, the image data is printed by the printer 17 in numerical order. In this manner, the saddle-stitch-form original is sequentially read from the outer page to the inner page, and the read image data is added with a number and stored, whereby the pages can be rearranged in page order and output. As a result, it is possible to save the trouble of rearranging the copies and the like in page order.

For example, when the HDD 18 can store 1000 pages of image data, a case where an 8-page weekly magazine is divided into pages and copied will be described. First, the staples of the saddle stitch are removed, and the document is set on the DF 15. At this time, the originals are set so that they can be read in order from the first page and the eighth page.

Next, the anti-booklet key on the operation display unit 14 is selected. As a result, the document is fed from the DF 15 to the reading unit 16, is read as image data by exposure, is inverted, and is similarly read on the back side and is discharged.

FIG. 2 shows a correspondence table 20 of page numbers of originals and image data numbers. From the first page of the manuscript 2,
Image data corresponding to pages in ascending order of pages 3 and 4 are numbered in ascending order of 1, 2, 3, 4 respectively, while
The image data corresponding to pages descending from the 8th page of the manuscript, such as pages 7, 6, and 5, are 1000, 999,
Numbers are added in descending order as 998 and 997.

After that, the image data are sorted in ascending order of number (1, 2, 3, 4, 997, 998, 999, 100).
0) is printed by the printer 17. Since the image data 1, 2, 999, and 1000 are ready to be printed when the first original is read, the printing operation is performed in either ascending or descending order in parallel with the original reading operation. May be. As a result, the operation speed up to completion of printing is increased. The printed image data is stored in the HDD 18.
The storage capacity of the HDD 18 can be effectively used.

<Embodiment 2> Embodiment 2 is an embodiment in which a double-sided spread original of the saddle-stitch type is sequentially read from an original including a continuous page on one side. First, the staples of the saddle stitch are removed, and the document is set on the DF 15. At this time, the originals are set in such a manner that the originals on which continuous pages are printed on one side can be read in order from the inner page.

Next, the anti-booklet key on the operation display unit 14 is selected. Thereby, the image reading device 10
Starts scanning the original. The document is fed from the DF 15 to the reading unit 16 and is read as image data by exposure, is inverted, and is similarly read on the back side and is discharged.

The read image data is divided into left and right in page units and stored in the HDD 18. At this time, the CPU 11 adds numbers to the read image data in the order of page numbers of the document.

That is, the image data corresponding to the pages descending from the smaller page number of the continuous pages on one side of the document are numbered in descending order, while the larger number of the pages continuous on one side of the document. The image data corresponding to the pages in ascending order from the page numbers are added in ascending order. However, the number added in descending order is smaller than the number added in ascending order. Note that the page number of the document and the number of the image data do not have to match, and the page order and the image data number may be in the same order.

Thereafter, the image data is printed by the printer 17 in the order of numbers. In this manner, the saddle-stitch-type original is sequentially read from the inside page to the outside page, and the read image data is added with a number and stored, so that the pages can be rearranged in page order and output. As a result, it is possible to save the trouble of rearranging the copies and the like in page order.

For example, when the HDD 18 can store 1000 pages of image data, a case where an 8-page weekly magazine is divided into pages and copied will be described. First, the staples of the saddle stitch are removed, and the document is set on the DF 15. At this time, the originals are set in such a manner that they can be read in order from the fourth page and the fifth page.

Next, the anti-booklet key on the operation display unit 14 is selected. As a result, the document is fed from the DF 15 to the reading unit 16, is read as image data by exposure, is inverted, and is similarly read on the back side and is discharged.

The read image data is divided into right and left so that it becomes a page unit and stored in the HDD 18. At this time, the CPU 11 adds numbers to the read image data in the order of page numbers of the document.

FIG. 3 shows a correspondence table 30 between page numbers of originals and image data numbers. From the fourth page of the manuscript 3,
Image data corresponding to pages in descending order from page 2 and page 1 are numbered in descending order such as 499, 498, 497 and 496, while pages 7, 6 and 8 from page 5 of the document are in ascending order. The image data corresponding to
The numbers are added in the ascending order of 00, 501, 502, 503. Then, the image data is sorted in ascending order of number (496-
The printer 17 prints in 503).

In the first or second embodiment, the number addition to the image data can be controlled by a very easy operation of adding in ascending order or descending order. It does not require complicated operations like the conventional booklet function for editing. Therefore, the load on the CPU 11 can be reduced.

When the image reading apparatus of the present invention is mounted on a network scanner, the image data is output by sending the image data sorted in numerical order to a terminal such as a personal computer. When the image data is installed in a facsimile, the image data is transmitted to the destination in the order of the image data.
