[0021]
In the figure, a bundle of documents placed upward on a document feeder 1 is sequentially conveyed to the platen glass surface 2 one by one from the top. At this time, the size of the conveyed document is detected by a document size detection sensor (not shown) provided in the document feeding device 1. When an original is set directly on the original platen glass surface 2, the size of the original can be detected by the reflection sensors 22 and 23.
[0022]
When a document is conveyed to the platen glass surface 2, the lamp 3 is turned on and the scanner unit 4 moves to irradiate the document. Light reflected from the original passes through a lens 8 via mirrors 5, 6, and 7 and enters an image sensor 9. When the document image input to the image sensor 9 is processed by the CPU circuit unit 37 (see FIG. 3), it is directly input to the exposure control unit 10 or temporarily stored in the image memory 35 (see FIG. 3). Are read out again and input to the exposure control unit 10.

[0040]
The operation of the copying machine having the above configuration will be described. FIG. 6 is a diagram showing a method of storing and reading a document image. FIG. 3A shows one storage capacity of the image memory, which is composed of 4662 × 6596 bits and can store an A3-size image. FIG. 7 is a diagram showing an image storage area of the image memory 35. The image storage area includes one image layout memory (area) and an image memory (area) capable of storing 100 images.
[0041]
First, a method of storing a document image in the image memory will be described. In the present embodiment, a case will be described in which an A4-size original placed on the original platen glass surface 2 is stored in the image memory.
[0042]
In FIG. 6B, originals are sequentially read in the direction of the arrow. First, when the (0,0) address is set as a start position, the X-direction counter is designated as up, and the Y-direction counter is designated as up, and when the first line is read, the Y-direction counter is increased and the (0,4661) address direction is read. Are written in order. Next, when the second line is read, the X-direction counter is incremented, and the data is sequentially written from the (1,0) address to the (1,4661) address. Reading and writing are repeated in this manner, and data is written up to the address (3297,4661).
[0043]
Next, the process of reading the image data written in the image memory is shown in FIGS. In FIG. 3C, the (3297,0) address of the first line of the image data is set as a start position, the X-direction counter is designated as down, the Y-direction counter is designated as up, and the X counter is designated in the (0,0) address direction. Are sequentially read down. Then, the Y counter is incremented, the second line is read, and the data is sequentially read from the (3297, 1) address in the (0, 1) direction.
[0044]
In FIG. 3D, the (0,0) address of the first line is set as a start position, the X-direction counter is specified to be up, and the Y-direction counter is specified to be up, and the Y counter is sequentially increased in the (0,4661) address direction. While reading. Then, the X counter is incremented, and the second line is read, and the data is sequentially read from the (1,0) address in the (1,4661) direction.
[0045]
Therefore, the original image of A4 can be rotated by reading by the method of FIG. 3C, and the image can be read without rotating by reading by the method of FIG.
[0046]
In FIG. 9E, by reading out the image data stored individually and writing the image data at a desired position in the image layout memory, different original images can be synthesized on the memory.
[0047]
Next, copy processing in the bookbinding mode will be described. FIG. 8 shows a copy process in the bookbinding mode. FIG. 1A shows input documents 601 to 608, and these documents are set on the document feeder 1 in a state where eight documents are stacked. FIG. 6B shows a state where bookbinding is performed by double-sided output. FIG. 9C shows the page distribution for the first and second sheets.
[0048]
FIGS. 9 and 10 are flowcharts showing the copy processing procedure when the bookbinding mode and the cover mode are designated. First, the originals 601 to 608 in FIG. When the cover mode is designated (see FIG. 5), the original to be copied on the cover is set on the originals 601 to 608 placed on the original feeder 1 (see FIG. 17A). In other words, the originals to be copied on the front cover and the inner cover, as well as the originals to be copied on the inner back cover and the back cover, are set on the originals 601 to 608. The order of setting is from top to bottom cover, inside cover, back inside cover, back cover. Thus, the user only has to set the cover original including the front cover and the back cover on the bundle of the original (text) originals stacked in order, and the user is free from confusion and as desired. The bookbinding mode can be executed. FIG. 17A shows a state of a document set in the setting of FIG. 5C.
[0049]
When the copy start key 203 is pressed with the original set in this way, the copy process starts.
[0050]
First, the document size is detected by the document size detection sensor or the reflection type sensors 22 and 23 provided in the document feeder 1 (step S801). Next, a sheet is selected and the selected sheet is checked (step S802).
[0051]
FIG. 11 is a flowchart showing the procedure of the sheet selection process. First, it is determined whether or not the paper ejection processing device 100 having the half-folding mechanism is mounted (step S1001). If the paper discharge processing device 100 is not mounted, the process of step S1004 is performed. On the other hand, if it is attached, it is determined whether or not the bookbinding mode is designated (step S1002).
[0052]
If the bookbinding mode has not been designated, the process of step S1004 is performed. On the other hand, if the bookbinding mode has been designated, it is determined whether or not the automatic paper selection has been designated (step S1003).
[0053]
If the automatic paper selection is designated, the processing of automatic paper selection 1 in step S1006 described below is performed. On the other hand, if it is not specified, it is determined whether or not the paper specified by the paper selection key is a paper in a landscape orientation (a direction in which the paper ejection direction is a long side). A sheet is selected (step S1010), and the process ends. On the other hand, if the paper is not the landscape paper, the fact that the selected paper is inappropriate is set in a predetermined RAM area (step S1009), and the process ends.
[0054]
On the other hand, in step S1004, it is determined whether or not the automatic paper selection has been designated, and if so, the process of automatic paper selection 2 in step S1007 described below is performed. If not specified, the process of step 1008 is performed. In step 1008, the paper designated by the paper selection key is selected, and this processing ends.
[0055]
FIG. 12 is a flowchart showing the processing procedure of automatic paper selection 1 in step S1006. First, the image size is calculated (step S1101). The image size is calculated based on the document size detected by the document size detection sensor or the reflection type sensors 22 and 23, scaling data set by the operation unit, other modes, and the like. For example, in the case of the bookbinding mode, the size is a size that can accommodate two originals, and is calculated as a size obtained by multiplying the detected original size by a scaling factor and doubling the short side.
[0056]
An optimal size is searched (step S1102). FIG. 13 is a diagram showing a table used for searching for an optimum size. The search for the optimum size is performed by selecting the smallest sheet that can contain the image size calculated in step S1101 from the sheets in the horizontal direction arranged in ascending order shown in FIG.
[0057]
According to the orientation and size of the paper in the installed paper cassette, a table of the size of the paper in the horizontal direction and a table of the size of the paper in the vertical direction are respectively created in a predetermined area in the RAM (step S1103).
[0058]
Based on the size searched in step S1102 and the horizontal table arranged in paper cassette size order in step S1103, a match is searched (step S1104), and it is determined whether there is a match (step S1105). If there is a match, the cassette is selected (step S1107), and the process ends. On the other hand, if there is no match, the second candidate is selected (step S1106). The selection of the second candidate is performed by searching the table created in step S1103 for a sheet of the minimum size that can accommodate the size searched in step S1102. If there is no paper cassette to be selected, the largest paper is selected and the process is terminated.
[0059]
FIG. 14 is a flowchart illustrating the processing procedure of the automatic paper selection 2 in step S1007. First, the image size is calculated (step 1201). The image size is calculated based on the original size detected by the original size detection sensors or the reflection type sensors 22 and 23, magnification data set by the operation unit, other modes, and the like.
[0060]
An optimum size is searched (step S1202). The search for the optimum size is performed by selecting the smallest sheet in which the image size calculated in step S1201 can be stored, from the vertically and horizontally arranged sheets shown in FIG. 13B. The mounted paper cassettes are arranged in size order, and the table is created in a predetermined area in the RAM (step S1203).
[0061]
A match is found from the table searched in step S1202 and the table in which the paper cassettes are arranged in size order in step S1203 (step S1204), and it is determined whether there is a match (step S1205). If there is a match, the cassette is selected (step S1207), and the process ends.
[0062]
On the other hand, if there is no match, the second candidate is selected (step S1206). The selection of the second candidate is performed by searching the table created in step S1203 for a sheet of the minimum size that includes the size searched in step S1202. If there is no paper cassette to be selected, the largest paper is selected and the process is terminated.
[0063]
Thus, the paper selection process in step S802 in FIG. 9 ends. Subsequently, as a result of the processing in step S802, a paper check is performed to determine whether the selected paper is inappropriate or whether the optimum size paper is selected (step S803).
[0064]
If the result of the paper check is OK, the process proceeds to step S806. On the other hand, if it is not OK, a message indicating that the paper is inappropriate is displayed on the liquid crystal display unit 238 of the operation unit (step S804), and the input of a start key for restart is waited (step S805). If the start key has been input, the process proceeds to step S806.
[0065]
In step S806, the original placed on the original feeder 1 is conveyed in order from the top to the original platen glass surface 2, the original image is read by the image sensor 9, and is sequentially stored in the image memory 35 shown in FIG. 7 (in order from the image memory 1). At the same time, the number N of documents is counted.
[0066]
When the cover mode is set and the setting for copying on the cover is performed, the number of originals N to be copied is corrected by subtracting the number of originals C (4 at the maximum) to be copied from the number of originals N counted by the equation (1) (step). S807). The number C of cover originals is equal to the number of check marks specified on the screen of FIG.
[0067]
N = N- (number of cover originals C to be copied) (1)
The number of output papers P is calculated from the number of originals N by equation (2) (step S808).
[0068]
P = QUAT [(N + 3) / 4] (2)
Here, QUAOT [X] represents an integer quotient of X, and is an integer value obtained by cutting off the decimal part of the result of the division.
[0069]
Next, the image reading order is calculated to create an image processing table indicating the image reading order (step S809). FIG. 15 is a flowchart showing the procedure for creating the image processing table in step S809. First, the value of the counter i is set to 0, and the number of output sheets P obtained in step S808 is set in the counter Pup and the counter Pdown (step S901).
[0070]
The output sheet number P is compared with the counter i (step S902). If the result of the comparison operation (i <P) is true, the process proceeds to step S903, and if false, the process ends. In step S903, calculation is performed according to equation (3), and the calculation is sequentially written in the image processing table indicating the image reading order. FIG. 16A is a diagram showing an image processing table when there is no cover or no copy is made on the cover. FIG. 16B is a diagram showing an image processing table when there are three cover originals as set in FIG. 5C.
[0071]
1st surface-left = 2 × Pdown + C
1st surface-right = 2 × Pup + 1 + C
2nd side-left = 2 × Pup + 2 + C
2nd side-right = 2 × Pdown-1 + C (3)
Here, C represents the number of cover originals to be copied.
[0072]
Then, the value 1 is added to the counter i, the value 1 is added to the counter Pup, and the value 1 is subtracted from the counter Pdown (step S904), and the process returns to step S902 again, and repeats the processes from step S902. An image processing table shown in FIG.
[0073]
Then, the images stored in the image memory 35 are laid out in the image layout memory in the image memory 35 according to the order of the image processing tables shown in FIG. 16 (step S810). In the example of FIG. 16A, first, an image is laid out by the above-described method so that the fourth image is on the left side of the image layout memory. Next, the fifth image is laid out on the right side of the image layout memory. Then, an image in the image layout memory is printed according to the start of printing on the first side (step S811). The next image is developed in the image layout memory as in step S810 (step S812). Then, the developed next image is similarly printed on the back surface of the sheet printed in step S811 (step S813). A paper check is performed in the same manner as in step S803 (step S814). If the result of the paper check is OK, the paper printed on both sides is printed. It is stored in the stack unit 110 (step S815). On the other hand, if the result of the paper check is not OK, the paper is discharged to the outside of the apparatus without being transported to the stack unit 110 (step S816).
[0074]
It is determined whether or not the above-described processing in step S810 and subsequent steps have been performed the number of times equal to the number of output sheets P (step S817). On the other hand, if the processing has been completed, it is determined whether or not the processing has been completed for the number of copies specified by the operation unit (step S818). If not completed, the processing of step S810 and subsequent steps is repeated. Move on to processing.
[0075]
In step S819, it is determined whether the cover mode is set. If the mode is not the cover mode, the processing after step S825 is performed.
[0076]
If the mode is the cover mode, a cover image processing table is created (step S820). FIG. 17B is a diagram illustrating an arrangement of a cover document image. FIG. 18 is a diagram showing a cover image processing table. Numerals 1, 2, 3, and 4 in FIG. 3B indicate page information of the read cover document image. Based on the mode specified by the operation unit shown in FIG. 9A, the page information of the print image shown in FIG. 10B is read, and the image layout processing is performed (step S821). The page information value 0 in the figure indicates that there is no image to be laid out. The image layout processing for the first and second surfaces is performed in steps S821 and S823, respectively. At this time, the image stored in the image memory 35 is stored in the image memory 35 according to the cover image processing table shown in FIG. The layout is performed in the image layout memory (step S821). The layout method is the same as the processing in step S810.
[0077]
At the start of printing on the first side, the image in the image layout memory is printed (step S822). As in step S821, the next image is developed in the image layout memory (step S823). Similarly, the next image is printed on the back surface of the sheet printed in step S822 (step S824).
[0078]
When the printing is completed, the processing after step S825 is performed. In step S825, it is determined whether or not the sheets are stacked in the half-fold path 104. If the sheets are stacked, a half-fold process is performed (step S826), and the sheet is discharged outside the apparatus. On the other hand, if not stacked, the process ends.
[0079]
By performing such processing, a bookbinding layout with a cover can be realized.
