FIG. 8 is a flowchart showing an example of a mark sheet processing procedure in the image processing apparatus according to the present embodiment. First, in step S801, the A4 size search sheets and print sheets stacked on the document feeder 101 of the reader unit 1 are sequentially conveyed one by one onto the platen glass 102 and read by the reader unit 1. The image information is stored in the A memory 506 of the file unit 5 based on the detection result by the photo sensor (not shown) for detecting the document size of the reader unit 1 according to the above-described signal flow.

Next, in step S702, the A memory 50
The CPU 516 reads the image data stored in No. 6, and the pattern 2011 is read at a predetermined position on the A memory 506.
˜2015 or patterns 2111 to 2115 are checked (pattern matching is performed). Next, in step S703, each of the patterns 2011 to 2015 examined in step S702 is compared with a template pattern prepared in advance to determine whether the image data stored in the A memory 506 is a predetermined mark sheet. To judge. If it is a predetermined mark sheet, the process proceeds to step S704, and if it is not the predetermined mark sheet, it is determined that the original document data is normal document data and step S70 is performed.
Proceed to 6.

In step S704, the above step S7 is performed.
The content of the image code 2028 or 2128 is read in order to specify the type of mark sheet determined in 03, and the setting content of the search sheet or the setting content of the print sheet is read according to the type of the mark sheet.

In the case of a search sheet, the offset coordinates from the reference position are calculated, and the automatic print setting field 20 after the search is performed.
Each mark column 2022 and 2023 in 21 is read. Here, to determine whether or not a mark is written in the first mark column 2022, for example, the number of black pixels in the first mark column 2022 is counted, and the number of black pixels is a predetermined threshold value. It may be judged by whether or not it exceeds.

Similarly, in the case of a print sheet, offset coordinates from the reference position are calculated, and the number of copies setting field 21 is sequentially set.
30, page designation setting field 2131, paper selection setting field 21
Each mark column in 32, double-sided print setting column 2133, sorter mode setting column 2134, and reduced layout setting column 2135 is read. Then, in step S705, the first mark column 20 read in step S704 is read.
After the content of the mark sheet 22 is set by the CPU 516 as the processing mode of the document to be read thereafter, the process proceeds to step S707.

On the other hand, if it is determined in step S703 that the mark sheet is not the predetermined mark sheet, step S7
After proceeding to 06, the read original is processed according to the processing mode set at step S705, and then the procedure goes to step S707.

In step S707, the document feeding device 10
CP whether all document stacks stacked on 1 have been read
The determination is made by the U 516, the CPU 1003, and the CPU 122 communicating with each other. If an unread original remains on the original feeding apparatus 101, the above step S70 is performed.
If the process returns to step 1 and all the originals have been read, step S7
Go to 08. In this step S708, the operation control is performed according to the contents set by the above-mentioned setting, and then this processing operation is ended.

By using the search sheet and the print sheet in combination as described above, the same search sheet is repeatedly used both when the print operation is performed after the search and when the print operation is not performed after the search. Is something that can be done.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG.

In the first embodiment, the operation of printing out the desired print form after the document search is performed by the combination of the search sheet and the print sheet, but in the present embodiment, the search sheet and the FAX (fax) are used. By using a combination of transmission sheets, an operation of transmitting in a desired FAX transmission mode after document retrieval is performed.

FIG. 9 is a diagram showing the format of a FAX transmission type mark sheet (hereinafter referred to as a FAX transmission sheet). In FIG. 9, 2210 is a FAX transmission sheet, 2211, 2212, 2213, 2214.
Reference numeral 2215 denotes a mark sheet detecting pattern, which is the mark sheet detecting pattern 2011 in FIG.
It is similar to 2012, 2013, 2014, and 2015. Reference numeral 2228 is an image code, in which information and the like for identifying the type of FAX transmission sheet are described. 223

When the search sheet and the FAX transmission sheet are used in combination as in this embodiment, the same processing is performed as when the search sheet and the print sheet of the first embodiment are used in combination.

As described in detail above, the search sheet and FAX
Even if the FAX transmission operation is performed after the search by using the transmission sheets in combination, the FAX sheet can be transmitted after the search.
Even when the X transmission operation is not performed, the same search sheet can be repeatedly used.

[0060]

As described above in detail, according to the image processing apparatus of the present invention, the mark sheet including the parameter whose type is changed every time and the mark sheet including the parameter whose setting is not changed every time are used. By dividing the mark sheet, you can repeatedly use the mark sheet that contains the parameters whose settings do not change, and by dividing the basic function and the applied and expanded functions for each mark sheet. Thus, it is possible to easily realize future function expansion.
