Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image editing apparatus for editing an image in a specific area of a document.

[0002]

2. Description of the Related Art Conventionally, for example, a copying machine is known as an image editing apparatus that edits an image read by an image scanner and outputs the edited image by a printing device. Some of such copying machines have an editing function of copying only a desired area of the original and skipping the other parts when the original is copied. To realize such an editing process, it is necessary to accurately select only the area to be copied from the original. Therefore, in the conventional image editing apparatus, the auxiliary platen glass is opened and closed, and as shown in FIG. 14, the corner of the description column is aligned with the mark by the backlight from the back of the document 50.
The original 50 is accurately placed at a predetermined position. If the original 50 is placed at an accurate position, the position is uniquely determined in a form of a form or the like, so that it is possible to select only the area to be copied. However, there is a drawback that the operation for placing the document 50 becomes very troublesome and takes time.

In order to solve the above problem, for example, in Japanese Patent Laid-Open No. 4-35150, the leading edge of the original 50 is detected by prescanning, and the position of the form to be read is determined with reference to this leading edge position. Identifying is disclosed. Further, for example, Japanese Utility Model Laid-Open No. 61-44658 discloses that the coordinates of the copy area and the skip area are patterned, a plurality of these patterns are registered, and the operator designates the pattern for each document. There is.

[0004]

However, the manuscript 5
In the conventional image editing apparatus that specifies the position of the image to be read based on the leading edge of 0, when considering the standard editing work, for example, a resident's card or a copy of a family register, etc. When reading and editing a manuscript 50 in which the distance from the leading end of the manuscript 50 to the entry field is different depending on the age of creation, even if the editing coordinates are determined on a form of a certain age, the position differs depending on the age of creation. For,
There was a problem that required fields were missing and privacy items could not be completely masked.

Further, in the conventional image editing apparatus in which a plurality of patterns are registered, the operator may not know which editing pattern to use only by looking at the manuscript 50. When reading and editing a copy of a family register, it is necessary to register an editing pattern for each lot because the size of the description field differs depending on the printed lot or the like. In addition, it is practically difficult to judge the difference in the size of the description field only by looking at it and select the optimum editing pattern.Therefore, you must measure the size of the description field on a scale and select the editing pattern. Therefore, there is a problem that the editing operation becomes troublesome.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide an image editing apparatus capable of automatically selecting an optimum editing pattern and improving an editing operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. A. Configuration of Example A-1. Configuration of Image Editing Apparatus FIG. 1 is a block diagram showing the configuration of the image editing apparatus according to the present invention. In the figure, reference numeral 1 is an image input terminal composed of an image sensor and the like.
To read an image and supply the image data to the image processing system 2. The image processing system 2 performs various kinds of image processing on the image data, for example, density adjustment and scaling, and supplies the image data to the image memory 3 and the reduction circuit 4.
The image memory 3 stores image data that has been subjected to image processing and serves as an editing work area for the image data. The reduction circuit 4 reduces the read image data, and outputs the image output terminal 5, the fax module 6 and the display controller 7.
Supply to. The image output terminal 5 is composed of a printer, for example, and prints and outputs the image data from the image memory 3 or the reduction circuit 4. The facsimile module 6 also transmits the image data from the reduction circuit 4 to a facsimile machine at a remote place via a public telephone line.

Next, the display controller 7 causes the display device 8 to entirely display the reduced image data. The display device 8 is composed of a CRT or the like, and is provided with a touch switch 9 for instructing an operation mode, an editing instruction, or the like by touching an icon displayed on the display device 8. The electric subsystem (ESS) 10 is a control device including a CPU 11, a non-volatile memory 12, a DMA (dynamic memory access) controller 13, and the like, and controls the operation of each of the above-mentioned units. By executing a predetermined program, the CPU 11 controls, for example, the reading of image data by the image input terminal 1 and the instruction of image processing by the image processing system 2. In particular, the CPU 11 automatically determines the area to be copied from the image data stored in the image memory 3 and supplies only the area to the image output terminal 5. The non-volatile memory 12 stores various parameters input from the above-mentioned touch switch 10 and necessary for editing, a coordinate table, a style table, etc., which will be described later. DMA controller 13
Directly accesses the image memory 3 without passing through the CPU 11 and transmits image data to each unit. The broken line in the figure indicates the data bus of the CPU 11, and the solid line indicates the data bus for transmitting image data.

A-2. Configuration of Non-Volatile Memory Next, the configuration of the above-mentioned non-volatile memory will be described. A coordinate table, a style table, a corner detection table, etc. are set in the non-volatile memory 12. Less than,
Each table will be described in order. (A) Coordinate table FIG. 2 is a schematic diagram for explaining the coordinate table stored in the non-volatile memory. In the figure, reference numeral 50 denotes a manuscript on which a copy of a family register is printed, and there are n description forms from a description form F1 to a description form Fn according to the generation age. Each of the description forms F1 to Fn is described in a fixed format, and is composed of a basic column, a column, a margin, a second column, and a third column from the right, which is surrounded by an outer frame 51 made of a solid line. The difference between the description format F1 to the description format Fn lies in the size of each column. Further, 50-1 to 50-n are coordinate tables in which the coordinates of two diagonal points of each field are stored for each description mode in order to distinguish each field in each illustrated format. , Is set in the nonvolatile memory 12. For example, in the coordinate table 50-1 for the description format F1, the coordinates of the basic column are (0, 0) on the diagonal A and (x on the diagonal B.
a, ye), (xa, 0) on the diagonal A as the coordinates of the first column,
(Xb, ye) on diagonal B, (xb, 0) on diagonal A as the second column coordinate, (xc, ye) on diagonal B, (xc, 0) on the diagonal A as third column coordinate, In the diagonal B, (xd, ye) is stored. Also, the coordinate table 5 of the description format Fn
In 0-n, the basic column coordinates are (0, 0) on the diagonal A, the diagonal B is (xf, yj), and the coordinates on the first column are (x, y).
f, 0), (xg, yj) on the diagonal B, (xg, 0) on the diagonal A as the second column, (xh, yj) on the diagonal B, and (A) on the diagonal A as the third column. xh, 0) and (xi,
yj) is stored. Similarly for other description formats, the coordinates of two points on the diagonal line of each column are stored for each description format. The coordinate tables 50-1 to 50-n are used to obtain the coordinates of the description column in the document 50 in the manual fixed-form editing mode and the automatic fixed-form editing mode described later.

(B) Style Table Next, FIG. 3 is a schematic diagram for explaining the style table stored in the nonvolatile memory. In the figure, 58
Is a style table, and for each length in the sub-scanning direction of the form in the document 50, a code indicating the description style of the form is stored. The description style of the form corresponds to the coordinate tables 50-1 to 50-n described above. The style table 58 is used to automatically determine the style of writing the form in the document 50 in the automatic fixed-form editing mode described later.

(C) Corner Detection Table Next, FIG. 4 is a schematic diagram for explaining the corner detection table stored in the nonvolatile memory. In the figure, reference numeral 60 is a corner detection table constituted by parameters for detecting the outer frame (see outer frame 51 of FIG. 2) 51 of the form in the document 50. The detection table 60 is used to detect the coordinates of at least two orthogonal sides forming the outer frame 51 when detecting the outer frame 51 of the document in the document 50.

B. Operation of Embodiment Next, the operation of this embodiment will be described. In the image editing apparatus according to the present embodiment, the standard editing mode for editing according to the description format stored in the nonvolatile memory 12 and the original 50 not corresponding to the description format stored in the nonvolatile memory 12 are used. Then, there is an edit mode of atypical editing in which the operator directly specifies the area to be copied. Also,
In the standard edit mode, a manual standard edit mode in which the operator instructs and edits the description style stored in the non-volatile memory 12, and an automatic edit mode in which the description style of the form in the manuscript 50 is automatically determined. There is. In any of the edit modes, first, the operator instructs the edit mode from the touch switch. This instruction is issued by the CPU 1 of the electric subsystem 10.
1 is supplied. Then, the CPU 11 processes the image data in the designated edit mode. The operation will be described below for each of the above-mentioned edit modes.

B-1. Fixed Form Editing Mode (a) Manual Fixed Form Editing Mode In this manual fixed form editing mode, although the position of the form in the document 50 is automatically detected, the operator indicates which description format the form of the document 50 corresponds to. . Here, FIG. 5 to FIG. 9 are flow charts for explaining the operation of the standard edit mode. Further, FIG. 10 is a schematic diagram showing an example of a format to be read in the standard edit mode, and FIG. 11 is a schematic diagram showing a read original document and its output result in the present embodiment. Operator touch switch 10
When the standard edit mode is instructed from the image input terminal 1 in step S1 shown in FIG.
The form (image) in the original 50 is read by and the density, magnification, etc. are adjusted by the image processing system 2. Next, in step S2, the image data subjected to the image processing is stored in the image memory 3. In step S3, for the image data stored in the image memory 3, as shown in FIG. 11, the image data of the image memory 3 is transferred from the address FSt in the FS direction which is the main scanning direction to the SS direction which is the sub scanning direction. Import image data. The address in the SS direction is initially set (=
0).

Next, in step S4, it is determined whether the image data is "1". Then, if the image data is not "1", that is, if it is a white background, the determination result in step S4 is "NO",
Go to step S5. In step S5, the address in the SS direction is incremented by "1", and then step S5.
Return to 3. Hereinafter, in steps S3 to S5, while advancing the address in the SS direction by "1", the image data is fetched and the position of "1" is searched. Then, when the image data becomes "1", that is, when some image (black dot) is detected, the determination result in step S4 becomes "YES", and the process proceeds to step S6.

In step S6, it is determined whether or not the image data continuously becomes "1" within the range of the address FSt ± u in the FS direction shown in FIG. That is, here, it is determined whether or not there is at least a straight line having a length of the address FSt ± u in the FS direction. When the image data does not become "1" continuously in the range of the address t ± u in the FS direction, that is, the black dots are not continuous at least in the above range, and the image data detected in step S4 is outside the form. If it is not the frame 51, the result of the determination in step S6 is "NO", and step S6
Return to 5. In step S5, the address in the SS direction is incremented as described above, and in step S3, the image data is fetched at the position of the new address in the SS direction. Then, steps S3 to S5 are repeatedly executed until the image data becomes "1" again.

On the other hand, when the image data becomes "1" and the image data continuously becomes "1" in the above range, the judgment result in step S6 is "YE".
S ”, and the process proceeds to step S7. That is, in this case, as shown in FIG. 11, the coordinate (SSm, FSt-u) is centered on the coordinate (SSm, FSt) in the FS direction.
There are continuous black dots in the range from the coordinates (SSm, FSt + u). Therefore, in this case, it is determined that the continuous black dots are part of the outer frame 51, and the address S in the SS direction is determined in step S7.
Remember Sm.

Next, at step S8, as shown in FIG. 11, the address in the FS direction is incremented by "v" to make the address FSt + v, and the routine proceeds to step S9 shown in FIG.
In step S9, the address FS direction address FSt + v
The image data is taken in from SS to SS direction. In addition, SS
It is assumed that the direction address is initially set (= 0). Next, in step S10, it is determined whether the image data is "1". Then, if the image data is not "1", that is, if it is a white background, the determination result in step S10 is "NO", and the process proceeds to step S11. In step S11, the SS-direction address is incremented by "1", and then the process returns to step S9. Hereinafter, in steps S9 to S11, while advancing the address in the SS direction by "1", the image data is fetched and the position of "1" is searched. And
When the image data becomes "1", that is, when a black dot is detected, the determination result in step S10 is "Y".
ES ”and the process proceeds to step S12.

In step S12, it is determined whether or not the image data continuously becomes "1" within the range of the address FSt + v ± u in the FS direction shown in FIG. That is, here, as in step S6 described above, at least F
It is determined whether or not there is a continuous black dot having a length of the address FSt + v ± u in the S direction. Then, when the image data does not continuously become “1” in the range of the address FSt + v ± u in the FS direction, that is, the black dots are not continuous in at least the above range, the image data detected in step S9 is outside the form. If it is not the frame 51, the determination result in step S12 is “NO”, and the process returns to step S11. In step S11, the address in the SS direction is incremented as described above, and in step S9, image data is fetched at the new position of the address in the SS direction. Then, steps S9 to S11 are repeatedly executed until the image data becomes "1" again.

On the other hand, if the image data becomes "1" and further the image data continuously becomes "1" in the above-mentioned range in step S12 described above, step S12
The result of the determination in step S13 is "YES" and step S13.
Go to. In step S13, it is determined that the continuous black dots are part of the outer frame 51, and the address in the SS direction is stored. Next, the process proceeds to step S14, and it is determined whether or not there are two or more same addresses in the SS direction stored in steps S7 and S13 described above. If there are not two or more same addresses in the SS direction, that is, if the black dots detected in steps S6 and S12 described above are not the outer frame 51 drawn in the FS direction, the determination result in step S14 is "NO"
Therefore, the process proceeds to step S8 shown in FIG. Step S8
Then, after further advancing the address in the FS direction by "v", in steps S9 to S12, the position in the SS direction where the image data continuously becomes "1" within a predetermined range is searched.
Then, if there are consecutive black dots that become "1" within the predetermined range, it is determined that the consecutive black dots are part of the outer frame 51, and the address in the SS direction is determined in step S13. Is stored and the process proceeds to step S14.

When there are two or more same addresses in the SS direction, that is, when a part of the outer frame 51 drawn in the FS direction is detected, the determination result in step S14 is "YES", and the steps shown in FIG. Proceed to S15.
In step S15, the same address having two or more points in the SS direction is determined and stored as the address in the SS direction. That is, in this step S15, the outer frame 51 shown in FIG.
The position of the outer frame line L1 drawn in the FS direction is determined.

Next, in step S16, image data is fetched in the FS direction from the address p in the SS direction shown in FIG. In step S17, it is determined whether or not the image data is "1". Then, if the image data is not "1", that is, if it is a white background, the determination result in step S17 is "NO", and the process proceeds to step S18. In step S18, the address in the FS direction is incremented by "1", and then step S
Return to 16. Hereinafter, in steps S16 to S18,
While advancing the address in the FS direction by "1", the image data is fetched and the position of "1" is searched.
Then, when the image data becomes "1", that is, when a black dot is detected, the determination result in step S17 becomes "YES", and the process proceeds to step S19.

In step S19, it is determined whether the image data continuously becomes "1" within the range of SSp ± q in the SS direction. That is, here, it is determined whether or not there is a black dot having a length in the range of address p ± q in at least the SS direction. Then, when the image data does not continuously become “1” in the range of the address SSp ± q in the SS direction, that is, the black dots are not continuous in at least the above range, and the black dot detected in step S17 is outside the form. If it is not part of the frame 51, the result of the determination in step S19 is "NO", and the process returns to step S18. In step S18, the address in the FS direction is incremented as described above, and step S1
At 6, the image data is taken in at a new address position in the SS direction. Then, steps S16 to S18 are repeatedly executed until the image data becomes "1" again. On the other hand, when the image data is "1" and the image data is continuously "1" in the above range, the determination result in step S19 is "YES", and the process proceeds to step S20. There will be continuous black dots in the above range. So in this case,
In step S20, it is determined that the continuous black dots are part of the outer frame 51, and the address in the FS direction is stored.

Next, the process proceeds to step S21 shown in FIG.
As shown in FIG. 11, the address in the SS direction is increased by “r” to be the address SSp + r, and the process proceeds to step S22. In step S22, the address S in the SS direction is given.
Image data is fetched from Sp + r in the FS direction. The address in the FS direction is assumed to be initialized (= 0). Next, in step S23, it is determined whether the image data is "1". Then, if the image data is not "1", that is, if it is a white background, the determination result in step S23 is "NO", and the process proceeds to step S24. In step S24, the address in the FS direction is incremented by "1", and then in step S24.
Return to 22. Hereinafter, in steps S22 to S24,
The position where the image data is “1” is searched while advancing the address in the FS direction by “1”. When the image data becomes "1", that is, when a black dot is detected, the determination result in step S23 is "YE."
S ”, and the process proceeds to step S25.

In step S25, it is determined whether the image data continuously becomes "1" within the range of SSp ± q in the SS direction. That is, here, similarly to step S19 described above, it is determined whether or not there is at least a black dot having a length of the address SSp ± q in the SS direction. Then, when the image data does not continuously become “1” in the range of SSp ± q in the SS direction,
That is, the black dots are not continuous in at least the above range, and the black dots detected in step S22 are the outer frames 5 of the form.
If it is not a part of 1, the determination result in step S25 is "NO", and the process returns to step S24. In step S24, the address in the FS direction is incremented as described above, and in step S22, the image data is captured at the new address position in the FS direction. Then, again until the image data becomes "1", step S2
2 to S24 are repeatedly executed.

On the other hand, when the image data is "1" and the image data is continuously "1" in the above range, the result of the determination in step S25 is "YES", and the process proceeds to step S26. move on. In step S26, it is determined that the continuous black dots are part of the outer frame 51, and the address in the FS direction is stored. Next, the process proceeds to step S27, and it is determined whether or not there are two or more same addresses in the FS direction stored in steps S8 and S26 described above. Then, when there are not two or more same addresses in the FS direction, that is, when the black dots detected in steps S8 and S26 described above are not the outer frame 51 drawn continuously in the SS direction, the determination result in step S27 Becomes "NO", and step S
Proceed to 21. In step S21, the address in the SS direction is further advanced by "r", and then steps S22 to S25.
Then, the image data is fetched, and the position where “1” is continuously obtained within a predetermined range is searched. Then, if there is a continuous black dot of "1" in the predetermined range, the address in the FS direction is stored in step S26, and the process proceeds to step S27.

When there are two or more same addresses in the FS direction, that is, when a part of the outer frame line L2 drawn in the SS direction of the outer frame 51 is detected, the determination result in step S27 is "YES", It proceeds to step S28.
In step S28, the same address having two or more points in the FS direction is determined and stored as the address in the FS direction. That is, in step S28, the position of the outer frame line L2 drawn in the SS direction shown in FIG. 11 is determined.

As described above, the position of the form is detected by detecting the outer frame 51 of the form in the original 50. Next, in step S29 shown in FIG.
The operator is made to input from the touch switch 10 which of the first, second, and third columns is to be copied, that is, to be output to the image output terminal 5.
In step S30, the outer frame 51 detected in the above-described process
The coordinate of the selected column is calculated in accordance with the coordinate table corresponding to the description format instructed by the operator from the coordinate table 50-1 to 50-n shown in FIG. Then, the image data on the image memory 3 is edited according to the coordinates of the selected column. Then, in step S32, the image data edited on the image memory 3 is output to the image output terminal 5 or the facsimile module 6. The image output terminal 5 prints the image data of the selected column. Here, FIG. 11 shows the read document 50.
2 is a schematic diagram showing the output result thereof. In the figure, the basic columns and 2 columns in the manuscript 50 are the selected columns, and only these basic columns and 2 columns are the image output terminal 5. Printed. When the data is output to the facsimile module 6, it is transmitted as a facsimile to a predetermined destination. It should be noted that the edited result may be displayed on the display 9 so that the operator can confirm it before outputting it to the image output terminal 5 or the facsimile module 6.

As described above, in the manual fixed-form editing mode, the position of the form in the document 50 is automatically detected, and the coordinates of the column are calculated according to the description style of the form and the column to be copied, which are instructed by the operator. Then, the image is output to the image output terminal 5 or the facsimile module 6. Since the position of the form is determined by detecting the outer frame 51 of the form in the document 50, it is necessary to set the document 50 at an accurate position or a preset position when placing the document 50 on the platen glass. Therefore, it is possible to copy only the necessary portion by simply abutting the original 50 on the corner, as in the case of normal copying. Further, even if the original 50 has a different distance from the leading end of the original 50 to the entry field depending on the generation age, the position of the entry field is directly detected. The image in the document 50 can be read.

(B) Automatic fixed-form editing mode The manual fixed-form editing mode described above was effective when the operator knew the description style of the original 50 to be edited. In many cases, it is not possible to easily identify the description format. In this case, the operator has to use the simple scale and the non-volatile memory 1 beside the apparatus in order to specify the description format of the manuscript 50.
The coordinate table corresponding to each description format stored in 2 is provided, and the size of the outer frame 51 of the form in the manuscript 50 is measured by the simple scale, and the description format is determined by the above correspondence table. . This automatic fixed-form edit mode automatically reduces the manuscript 50 in order to improve the complexity of the work described above.
By detecting the description format of, the burden on the operator is reduced and the productivity is improved.

Here, FIG. 12 is a schematic diagram for explaining the operation in the standard edit mode. When the operator gives an instruction for the automatic fixed-form editing mode from the touch switch 10, first, according to the same algorithm as the above-mentioned flowchart,
After detecting the outer frame line L1 drawn in the FS direction, which is the main scanning direction, and determining the coordinates SS1 of this outer frame line L1, then detecting the outer frame line L2 drawn in the SS direction, Further, the outer frame line L3 drawn in the FS direction from the final end side is detected, and the coordinate SS2 of this outer frame line L3 is determined. Next, the difference between the coordinate SS1 and the coordinate SS2 (SS1-
Calculate SS2). Then, the description style corresponding to the difference (SS1-SS2) is determined by referring to the style table 58 shown in FIG. 3 stored in the non-volatile memory 11. When the form of the form on the manuscript 50 is decided, the coordinates of two points on the diagonal line of each column are decided from the coordinate table 50-i (i = 1, 2, ..., N) shown in FIG.

In the same manner as in the manual fixed-form editing mode described above, the operator is asked which of the basic, first, second, and third columns is to be copied, that is, to be output to the image output terminal 5. Touch switch 10
Input from. Next, according to the coordinate table 50-i of the description format determined by the above-described processing, the image memory 3
Edit the image data above. Next, the image memory 3
The image data edited above is output to the image output terminal 5 or the facsimile module 6. The image output terminal 5 prints the image data of the selected column. When the data is output to the facsimile module 6, it is transmitted as a facsimile to a predetermined destination. Image output terminal 5 or facsimile module 6
The edited result may be displayed on the display 9 so that the operator can confirm the edited result before output to the.

As described above, in the automatic fixed-form editing mode, the position of the form in the original 50 is automatically detected, the form of the form in the original 50 is automatically specified, and based on these information, The coordinates of the column to be copied designated by the operator are calculated and output to the image output terminal 5 or the facsimile module 6. Since the position of the form is determined by detecting the outer frame 51 of the form in the document 50, it is necessary to set the document 50 at an accurate position or a preset position when placing the document 50 on the platen glass. Disappears. Further, since the form of the form in the document 50 can be automatically detected, the burden on the operator can be reduced and the productivity can be improved.

B-2. Non-Standard Editing Mode Next, in the non-standard editing mode, when the description style of the form in the manuscript 50 is not registered in the non-volatile memory 12,
The operator directly specifies the area to be copied while confirming it on the display device 8. That is, in this atypical editing mode, the position of the form in the document 50 is set to the position shown in FIG.
It is automatically detected by the same algorithm as the flowchart shown in FIG. On the other hand, the operator designates which area of the form of the document 50 to copy by looking at the display device 8. Here, FIG. 13 is a schematic diagram for explaining the operation in the non-standardized edit mode. When the operator designates the atypical editing mode from the touch switch 9, first, the image of the original 50 is read by the image input terminal 1, and the density, magnification, etc. are adjusted by the image processing system 2. Next, the image data subjected to the above image processing is stored in the image memory 3, reduced by the reduction circuit 4, and supplied to the display controller 7. The display controller 7 entirely displays the reduced image data on the display device 8.

The image data stored in the image memory 3 is processed by the same algorithm as in the flowcharts shown in FIGS. 5 to 8 described above, and the coordinates of the outer frame 51 of the document in the document 50 are determined. To be done. Next, the image data displayed on the display device 8 (form)
As shown in FIG. 13, a bar B for selecting a column to be copied based on the coordinates of the determined outer frame 51.
Two of 1, B2, B3, and B4 are displayed in the FS and SS directions, respectively. The FS direction bar B1 is displayed on the outer frame line L1, and the SS direction bar B3 is displayed on the outer frame line L2.
Displayed above. At this time, the bar B2 in the FS direction and the bar B4 in the SS direction are displayed at positions preset in the nonvolatile memory 12, respectively.

Here, the operator designates the entry column to be copied by the bar B2. In the designation method, when the corner of the desired entry field is touched while looking at the image displayed on the display device 8, the bar B2 moves following the touched X coordinate position. After adjusting to the desired position,
When the enter key on the touch switch 9 is touched, the address of the area surrounded by the bars B1 to B4 is calculated, and then the corresponding area is highlighted. Further, when there is a description column to be added, the above operation is repeated. Further, the designation of the displayed original 50 is completed, and the second original 5
When combining with 0, the next original key on the touch switch 9 is touched, the next original 50 is read, and then 1
Specify the same as the first sheet. Then, with the touch switch 9,
Instruct output to the image output terminal 5 or the facsimile module 6. At the image output terminal 5, the image data in the selected description field is printed. When the data is output to the facsimile module 6, it is transmitted as a facsimile to a predetermined destination. In addition, before outputting to the image output terminal 5 or the facsimile module 6,
The edited result may be displayed on the display 9 so that the operator can confirm it.

As described above, in the non-standardized editing mode, the position of the form in the document 50 is automatically detected by detecting the outer frame 51, and the operator confirms the area to be copied on the display device 8. However, since the document 50 is directly designated, it is not necessary to set the document 50 on a platen glass at an accurate position or at a preset position. Also, since the area to be copied can be selected while looking at the display device 8,
It is possible to reduce the burden on the operator and improve productivity.
