  A timer circuit 220 and a communication line I / F 222 are connected to the I / O 210. Further, the I / O 210 is connected to the image reading device 18 and the image forming device 12.

  Here, as shown in FIGS. 6 and 8, when the document 72 is a drawing or the like, the title (specific image) 74 is displayed on the document 72 in the lower right corner when viewed from the front (in FIG. 6, the top side is facing right). May be provided. In the title 74, identification information such as a name and a number for specifying a drawing is recorded, which can be a table of contents.

  By the way, when the drawing of a large size (for example, A0, A1 size, etc. in JIS standard) is the original 72, the recording paper 76 after the image formation (see FIGS. 7 and 9) is folded and stored or carried. There are many cases.

  For this reason, it is preferable that the title 74A comes to a position on the recording paper 76 that is easy to see even after being folded (after being folded). More specifically, an area in which an identification frame is recorded may be provided on the forefront of the folded recording paper 76.

  In the image forming apparatus 14 of the present embodiment, a unit 14A (see FIG. 3) that automatically executes a folding process is added as a post-processing function.

  There are a plurality of types of paper folding, and representative examples include “fan folding” as shown in FIG. 10, “cross folding” as shown in FIG. 11, “special folding” as shown in FIG. is there.

  At this time, as shown in Table 1 below, the optimum position of the title 74 is uniquely determined according to the size of the recording paper 76 to be designated and the paper folding form.

However, if the designated size paper at the time of image formation is “out of paper”, an alternative paper is selected, and the recording paper may be output in a direction different from the normal output direction. The same thing can happen when specifying the magnification. When the folding process is executed in this state, there is a possibility that the title 74 is not visible on the forefront of the recording sheet after the folding.

  Therefore, in the present embodiment, the position of the title 74A is optimized by comparing the orientation of the image data read by the image reading device 18 with the orientation of the recording paper 76 that is actually applied. As described above, the image data is rotated in units of 90 °. In other words, the image data is adjusted in accordance with the selected recording paper 76 before the image forming apparatus 14 forms an image.

  FIG. 4 is a functional block diagram for image data rotation position control in the main control unit 200. Note that FIG. 4 is specialized for image data rotation position control and is divided into blocks according to functions, and does not limit the hardware configuration.

  Information input by operating the operation panel 30 (see FIG. 3) is analyzed by the reception information analysis unit 100 and classified into document information, paper source information, and paper folding information.

  The reception information analysis unit 100 is connected to the document information acquisition unit 102, the paper source information acquisition unit 104, and the paper folding information acquisition unit 106. The document information acquisition unit 102 acquires document information from the classified information. The paper source information acquisition unit 104 acquires paper source information from the classified information. The paper folding information acquisition unit 106 acquires paper folding information from the classified information.

  The document information acquisition unit 102, the paper source information acquisition unit 104, and the paper folding information acquisition unit 106 are connected. The optimum title position determination unit 108 is connected. The optimum title position determination unit 108 is connected to the title position setting table memory 110. The title position setting table memory 110 stores a table for specifying the optimum position of the title 74 (74A) from the relationship between the paper size and the paper folding form as shown in Table 1 above.

  The optimum title position determination unit 108 determines the title based on information (original information, paper source information, paper folding information) from the original information acquisition unit 102, paper source information acquisition unit 104, and paper folding information acquisition unit 106. The optimum position of the title 74A is determined from a table (see Table 1) stored in the position setting table memory 110, and the determination result is sent to the document image / output sheet orientation comparing unit 112.

  The original image / output paper direction comparison unit 112 compares the direction of the image data of the original 72 read by the image reading device 18 with the direction of the recording paper 76 actually applied (the direction of the discharge direction). The result is sent to the title position comparison unit 114.

  The title position comparison unit 114 executes different comparison controls based on the comparison result (match / mismatch) in the document image / output paper direction comparison unit 112. That is, if the orientation of the image data and the orientation of the discharge direction of the recording paper 76 are the same (match), the rotation of the image data is specified as 0 ° or 180 °. On the other hand, if the direction of the image data and the direction of the discharge direction of the recording paper 76 are different (mismatch), the rotation of the image data is specified as 90 ° or 270 °.

  The comparison result of the title position comparison unit 114 is sent to the image rotation angle specifying unit 116 and specified as one of the rotation angles (0 °, 90 °, 180 °, 270 °) of the image data. In other words, the image data is rotated in units of 90 °.

  The image rotation angle specifying unit 116 is connected to the read image rotation instruction unit 118, and instructs the image reading device 18 to rotate the read image data from the read image rotation instruction unit 118.

  The operation of this embodiment will be described below.

  The document is placed on the document table 20 of the document preparation device 12 and sent to the image reading device 18. At this time, the document is fed into the image reading device 18 while being aligned by the document guide 26. In the image reading device 18, the image stored in the document is read by the line sensor while being conveyed at a constant speed (sub scanning).

  The read image data is sent to the image forming apparatus 14, and the paper loaded in the paper loading sections 50, 52, 54 or the paper inserted from the manual feed tray 48 is sent out to form an image on the paper. .

  FIG. 5 is a flowchart showing a procedure for controlling the image data rotation position.

  In step 150, it is determined whether image reading information (original information, paper source information, paper folding information) has been received. If a negative determination is made, this routine ends.

  If the determination in step 150 is affirmative, the process proceeds to step 152 to read the title position setting table (see Table 1), and then the process proceeds to step 154 to accept the received image reading information and the table in Table 1. To determine the optimum title position.

  In the next step 156, the reading direction of the original 72 is compared with the discharge direction of the recording paper 76. As a result of the comparison in step 156, if it is determined that they match, the process proceeds to step 158 to compare the position of the title 74 of the document 72 with the optimum position of the title 74A on the recording sheet 76. . If it is determined in step 158 that they match, the process proceeds to step 160 where the rotation angle of the image data is set to 0 ° (that is, the current position), and the process proceeds to step 178. If it is determined in step 158 that they do not match, the process proceeds to step 162, the rotation angle of the image data is set to 180 °, and the process proceeds to step 178.

  That is, when the conveyance direction of the original 72 and the discharge direction of the recording paper coincide with each other, whether the original 72 is in the vertical direction (see FIG. 6) or the horizontal direction (see FIG. 8), only the upside down direction is reversed. As a result, the result is 0 ° or 180 °.

  On the other hand, if it is determined in step 156 that they do not match, the process proceeds to step 164 to determine the position of the title 74 on the document 72. This is determined from the received image reading information, and is determined to be “lower left” or “lower right”. “Lower left” indicates that the original 72 is in the vertical direction (see FIGS. 6 and 7A), and “Lower right” indicates that the original 72 is in the horizontal direction (see FIGS. 8 and 9A).

  If “lower left” is determined in step 164, the process proceeds to step 166 to determine the optimum position of the title 74 </ b> A of the output recording sheet 76. That is, since the recording paper 76 different from the orientation (vertical orientation) of the original 72 is in the landscape orientation, the optimal position of the title 74A is “lower right” (see FIG. 7B) or “upper left” (FIG. 7 ( C)).

  If it is determined as “lower right” in step 166, the process proceeds to step 168, the rotation angle of the image data is set to 90 ° counterclockwise, and the process proceeds to step 178. If it is determined in step 166 that it is “upper left”, the process proceeds to step 170, the rotation angle of the image data is set to 270 ° counterclockwise, and the process proceeds to step 178.

  On the other hand, if “lower right” is determined in step 164, the process proceeds to step 172 to determine the optimum position of the title 74 A of the output recording paper 76. That is, since the recording paper 76 that is different from the orientation of the document 72 (landscape orientation) is in portrait orientation, the optimum position of the title 74A is “lower left” (see FIG. 9B) or “upper right” (FIG. 9C). ))).

  If it is determined as “lower left” in step 172, the process proceeds to step 174, the rotation angle of the image data is set to 2700 ° counterclockwise, and the process proceeds to step 178. If it is determined in step 172 that it is “upper right”, the process proceeds to step 176, the rotation angle of the image data is set to 90 ° counterclockwise, and the process proceeds to step 178.

  In step 178, the set rotation angle of the image data is sent to the image reading device 18, and the rotation of the image data is instructed. Then, this routine ends.

(Modification)
In the present embodiment, a single job is described as an example of the process from reading the original 72 to image formation and then paper folding (hereinafter also referred to as “job”). A case where “multi-job sort” is received as a command will be described.

  “Multi-job sort” is a single image reading process in which not only the number of copies but also a copy function is set for each of a plurality of distribution destinations.

  As shown in FIG. 13, distribution destination information is set in advance from the operation panel 30. This setting information is set in a multi-job memory managed by the operation control unit 38.

  Here, in the distribution destination 1 (job memory 1), two sets of originals are set so as to be output by fan folding with the same magnification output. In the distribution destination 2 (job memory 2), two sets of originals are set so that they are output without folding in A4 reduced output. In the distribution destination 3 (job memory 3), three copies of the original set are output at the same magnification, and the third stamp is synthesized and set so as to be output by special folding.

  The operation of multi-job sorting of the two originals 72 by designating these three distribution destinations will be described.

  By operating the operation panel 30, the three job memories 1 to 3 shown in FIG. 13 are set, and multi-job sorting is started.

  On the operation panel 30, the position of the title 74 of the document 72 is set to “lower left”, and image reading of the first document 72 (document A) is started. When conveyance of the document 72 is started, document data is transferred from the image reading device 18 to the main control unit 200, and is compressed and stored in the HDD 218 or the like, for example.

  Since all of the distribution destinations 1 are output at the same magnification, the original image with a magnification of 100% is transferred to the main cotton troll unit 200.

  Here, in the rotation angle determination process as shown in FIG. 5, the rotation angle is 0 °, so the image is compressed without being rotated and stored in the HDD 218.

  Since the distribution destination 2 is reduced by 25% (A4 output of the A0 original 72 is designated), image data reduced by 25% is created and transferred to the main control unit 200. In the distribution destination 2, since paper folding is not designated, the image data is compressed without being rotated and stored in the HDD 218 or the like.

  Since all of the distribution destinations 3 are the same-size vertical output, a document image with a magnification of 100% is created and transferred to the main control unit 200. In the rotation angle determination process as shown in FIG. 5, the rotation angle is 0 °, so the image is compressed without being rotated and stored in the HDD 218.

    Next, similarly, the position of the title 74 of the document 72 is set to “lower left”, and image reading of the second document 72 (document B) is started.

  Since all the distribution destinations 1 are output at the same magnification, the original image with a magnification of 100% is transferred to the main control unit 200. In the rotation angle determination process as shown in FIG. 5, the rotation angle is 0 °, so the image is compressed without being rotated and stored in the HDD 218.

  Since the distribution destination 2 is reduced by 35.3% (A4 output of an A1 document is designated), image data reduced by 35.3% is created and transferred to the main control unit 200. In the distribution destination 2, since paper folding is not designated, the image data is compressed without being rotated and stored in the HDD 218 or the like.

  Since all of the distribution destinations 3 are output at the same magnification, a document image with a magnification of 100% is created and transferred to the main controller 200. In the rotation angle determination process as shown in FIG. 5, the rotation angle is 180 °, so that the image data is rotated 180 ° and compressed and stored in the HDD 218.

  When the end button on the operation panel 30 is pressed, multi-job sort output is started.

  At this time, a table as shown in Table 2 below is created.

This indicates that for the distribution destination 1, the image data of the original A1 not rotated at a magnification of 100% and the image data of the original B1 not rotated at a magnification of 100% are output by fan folding. .

  Next, for distribution destination 2, three sets of image data of document A2 not rotated at a magnification of 25% and image data of document B2 not rotated at a magnification of 35.3% are output without folding. ing.

  Further, for the distribution destination 3, the image data of the original A3 that has not been rotated at a magnification of 10% and the original B3 that has been rotated by 180 ° at a magnification of 100% are output in three copies.

  When the multi-job sort page generation is started, the main control unit 2000 refers to a table as shown in Table 2 and outputs image data of document number 1 of copy number 1 and image data of document number 2; Next, the image data of document number 1 of copy number 2 and the image data of document number 2 are output. This is repeated until the last part number.

  Distribution destination 1 and distribution destination 3 have the same magnification of 100%, but the paper folding method is different. However, by performing the processing as described above, the title 74A is recorded on the recording paper 76 and output at the optimum position by reading the same document.
