FIG. 7 is a diagram for explaining a method of calculating the print position correction data 20b of FIG. 1, and portions not related to the print position correction are omitted.

Hereinafter, the processing procedure of the positional deviation correction value generation processing will be described with reference to FIG.
The operation of the misregistration correction value generation process of FIG. 3 is started. When the panel control unit 12 is operated and the misregistration confirmation pattern 30 of FIG. 2 is printed in step S1, the printer unit 15 is stored in the flash ROM 20. The registered misregistration confirmation pattern data 20c is printed on the printing paper. Thereby, a misregistration confirmation pattern as shown in FIG. 4 is printed on the printing paper. The printed misregistration confirmation pattern of FIG. 4 includes a misalignment amount by the printer unit 15 and is thus slightly skewed clockwise, for example. In step S2, the printing result of the misregistration confirmation pattern as shown in FIG. 4 is set on the flat bed portion 13a of the scanner unit 13. Then, in step S3, the panel control unit 12 is operated, and the misregistration confirmation pattern in FIG. Read the print result.

  In step S <b> 4, the positional deviation confirmation image acquisition unit 21 acquires the flat bed positional deviation confirmation image read by the flat bed unit 13 a of the scanner unit 13. At the time of reading the flat bed position deviation confirmation image, the entire glass surface of the flat bed portion 13a is read in order to read the entire print result of FIG. 4 set in the glass surface of the flat bed portion 13a. An example of the flatbed position deviation confirmation image is shown in FIG. The image in FIG. 5 includes the amount of deviation caused by the previous printer unit 15 and the amount of deviation caused by the current flatbed portion 13a, so that, for example, the image is greatly skewed clockwise.

  In step S5, the misalignment correction data generation unit 22 calculates a skew amount at the time of reading the flat bed from the flat bed misalignment confirmation image of FIG. 5, and generates the flat bed position correction data 20a. A diagram for explaining a method of calculating the flatbed position correction data 20a is shown in FIG.

  Since the difference between the flat bed position deviation confirmation image of FIG. 5 and the printing result of the position deviation confirmation pattern of FIG. 4 is the deviation amount by the flat bed portion 13a, flat bed position correction data 20a for correcting this deviation amount. (= AdjS_fb) can be calculated by the following equation (1), for example.

However,
RT_fb: From the right edge of the flatbed misalignment confirmation image to the right edge of the document
Length RB_fb: From the right end of the flatbed misalignment confirmation image to the right rear end of the document
Length L_fb: Length from the right edge of the document to the right rear edge of the document S_fb: Skew amount when reading the flatbed

  In step S6, the generated flatbed position correction data 20a is stored in the flash ROM 20.

  Next, in step S7, the misalignment correction data generation unit 22 calculates a skew amount during printing from the flatbed misalignment confirmation image of FIG. 5, and generates print position correction data 20b. FIG. 7 is a diagram for explaining a calculation method in the print position correction data 20b.

  Since the difference between the printing result of the misregistration confirmation pattern in FIG. 4 and the misregistration confirmation pattern in FIG. 2 is the misregistration amount by the printer unit 15, print position correction data 20b (= adjS_pn) for correcting the misregistration amount. Can be calculated by the following equation (2), for example.

However,
RT_pn: TR pattern from the right edge of the document in the flatbed misalignment confirmation image
Length to the right leading edge RB_pn: BR pattern from the right edge of the document in the flatbed position confirmation image
Length to the right rear end L_pn: BR from the right end of the TR pattern of the flatbed position confirmation image
Length to right rear end of pattern S_fb: Skew amount when reading flatbed

  In step S8, the generated print position correction data 20b is stored in the flash ROM 20, and the operation of the misregistration correction value generation process ends.

  FIG. 8 is a flowchart showing an outline of the misregistration correction process in the image processing apparatus 10 of FIG.

  FIG. 9 is a diagram for explaining the misalignment correction processing at the time of flatbed copying in FIG. In FIG. 9, adjS_fb is a misregistration correction amount at the time of flatbed reading, and adjS_pn is a misregistration correction amount at the time of printing.

Hereinafter, the procedure of the misalignment correction process of FIG. 1 will be described with reference to FIG.
The operation of the misregistration correction process in FIG. 8 is started, and a document is set on the flat bed portion 13a of the scanner portion 13 in step S10. In step S11, the panel controller 12 is operated to perform a copy, scan, or fax transmission operation, and read the original on the flat bed portion 13a. In step S12, the panel control unit 12 determines whether or not the function to be executed is a flatbed copy. If flatbed copy (Yes), the process proceeds to step S13. If scan or fax transmission (No), step S16 is performed. Proceed to

  In step S13, since the function to be executed is copying, the image processing unit 14 adds the flat bed position correction data 20a (= adjS_fb) stored in the flash ROM 20 and the print position correction data 20b (= adiS_pn). Is calculated, and the read image is rotated in the counterclockwise direction, for example, by the amount of the calculation result, thereby correcting the positional deviation optimum for the copy result. The misalignment correction process in this flat bed copy is shown in FIG.

  In step S <b> 14, the image processing unit 14 performs image processing of the copy subjected to the positional deviation correction. In step S <b> 15, the printer unit 15 performs printing on the printing paper, and ends the positional deviation correction processing.

  In step S12, when the function to be executed is scan or fax transmission other than copying (No), in step S16, the image processing unit 14 determines the value of the flatbed position correction data 20a (= adjS_fb) stored in the flash ROM 20. By rotating the read image by, for example, counterclockwise, the positional deviation correction optimum for the flatbed reading result is performed.

  In step S17, the image processing unit 14 performs image processing for scan or fax transmission that has been corrected for misalignment, and in step S18, the image data that is the image processing result is transmitted by the fax communication control unit 16 or the network communication control unit 17. Is transmitted and the operation of the misregistration correction process is terminated.

  According to the first embodiment, it is possible to correct the skew at the time of reading the flat bed and at the time of printing using the result of printing the misregistration confirmation pattern of FIG. 2 on the printing paper. In addition, since the printing result of the misalignment confirmation pattern in FIG. 4 is used as a document, there is an advantage that it is not necessary to prepare a dedicated chart for misalignment correction of the scanner unit 13 (for example, the flatbed unit 13a).

(Effect of Example 1)
According to the first embodiment, from the result of reading the printing result of the positional deviation confirmation pattern in FIG. 4 by the flat bed portion 13a, the positional deviation at the time of flat bed reading generated by the mounting accuracy of the image sensor in the scanner portion 13; It is possible to correct both the misalignment of the printer unit 15 that occurs during conveyance of the printing paper, and to improve the misalignment during copying. In addition, after correcting the positional deviation at the time of reading the flatbed, the image processing of scanning or fax transmission is performed and the result of the image processing is transmitted, so that it is possible to receive the image without positional deviation on the receiving side.
