The touch panel detection circuit will be briefly described. As shown in FIG. 7, terminals X1 and X2 at both ends of a touch panel 92a having a resistance film bonded in the X direction, and a touch panel 92b having a resistance film bonded in the Y direction. A coordinate position is calculated by applying a voltage to each of the terminals Y1 and Y2 at both ends of and detecting the potential at the pressed position on the resistance film.

That is, the touch panel detection circuit is shown in FIG.
A touch panel controller 71 is provided as shown in, and a signal from the controller 71 is supplied to the OR gate 72. The output signal of the OR gate 72 is directly supplied as a control input to the three-state buffers 74 and 75 and the inverter 79 that constitutes the multiplexer 80, and is also supplied as a control input to the three-state buffers 75 and 76 via the inverter 73. . The multiplexer 80 is composed of two sets of transmission gates and an inverter 79 as shown in the figure.

The signal supplied to the OR gate 72 is supplied to the input side of the three-state buffer 74 via the inverter 78, and the output side thereof is connected to one input side of the multiplexer 80. Three-state buffer 7
5V is applied to the input side of 5, and its output side is connected to the other input side of the multiplexer 80. The input side of the three-state buffer 76 is grounded, and the output side thereof is connected to the terminal Y2. Three-state buffer 7

Next, the operation of the first embodiment configured as above will be described. FIG. 11 shows an example of a menu screen of the user program setting screen which is displayed on the display unit 53 of the operation unit unit 5 and which can be set by the user. On this screen, as shown in the figure, since the touch panel key is set to the item number, by pressing the part of the number, the screen is expanded to the item corresponding to the pressed number. In the first embodiment, when the user presses the number "4" on the screen, the user can select the staple position setting in which the staple position can be set, and when the number "5" on the screen is pressed, the punching position is changed. Selectable hole position settings.

Therefore, when the user presses the number "4" on the screen, the contents of the screen are changed to the stapling position setting screen as shown in FIG. Therefore, the user sets two staple positions with respect to the original while looking at this screen. For this input, press the part that displays the input value on the screen to invert black and white, then enter the set number of millimeters with the ten keys 41 and press #
Set by pressing the key.

On the other hand, the user selects the number "5" on the screen.
When is pressed, the contents of the screen are changed to the screen for setting the punching position as shown in FIG. Therefore, the user sets two punching positions for the document while looking at this screen. This input is set by pressing the part for displaying the input value on the screen to invert black and white, inputting the set number of millimeters with the ten keys 41, and pressing the # key.

Next, when the user presses the position confirmation mode key 51 of the operation unit unit 5 shown in FIG. 4, the position confirmation mode is selected and the display contents of the display unit 53 of the operation unit unit 5 are as shown in FIG. Is changed to. Since there are two position confirmation modes, a staple position confirmation mode and a punching position confirmation mode, the user can select one of the modes by pressing the respective execution keys. Now, when the user selects the staple position confirmation mode,
Since the processing operation shown in the flowchart of FIG. 19 is performed, it will be described with reference to this.

First, the staple position confirmation key is pressed (O
N) is determined (step 1), and if it is determined that the button has been pressed, the image reading unit 2 performs a document reading operation by a prescan operation (step 2). The image of the original read by the image reading unit 2 is combined with the staple position data preset as described above by the image processing unit 3 (step 3), and the combined image is displayed on the image display unit 7. It is sent and displayed on the LCD panel 26 of the image display unit 7 (step 4). The image composition processing by the image processing unit 3 may be executed using a memory for composition / editing or may be executed by processing / editing.

Here, the display section 26 of the image display unit 7
As shown in FIG. 15, when the combined image displayed in FIG. 15 does not overlap the original image and the staple position, the user may select (press) the confirmation key on the display screen. On the other hand, when the composite image overlaps the original image and the staple position as shown in FIG. 16, a message to that effect is displayed on the screen to alert the user. Therefore, in order to eliminate the overlap, the user
The shift key or the scaling key on the display screen may be selected. It should be noted that the warning for calling out that the images are overlapped and abnormal as described above may be accompanied by voice in the above display, or may be only voice.

Therefore, after the above-mentioned composite image is displayed, it is first judged whether or not the confirmation key is selected (ON) (step 5), and when it is judged that the confirmation key is selected (step 5; Y), the process is terminated without performing image processing. On the other hand, when the confirmation key is not selected (step 5; N), it is determined whether the shift key is selected (step 6). As a result, when it is determined that the shift key has been selected (step 6; Y), the portion where the original image and the staple position overlap is calculated, and the original image is shifted (moved) until it does not overlap. Parameters are set in the reading unit (scanner) 2 and the image processing unit 3 (step 7).

On the other hand, if it is determined that the shift key is not selected (step 6; N), then it is determined whether the scaling key is selected (step 8). as a result,
When it is determined that the scaling key is selected (step 8;
Y), a portion where the original image and the staple position overlap is calculated, a reduction ratio that does not overlap is calculated, and the obtained reduction ratio is set in the image reading unit (scanner) 2 and the image processing unit 3 (step 9). ). When it is determined in step 8 that the scaling key has not been selected (step 8; N), the process returns to step 4, and the selection of the next key is awaited while the combined image display is continued. After that, since the original can be copied in a state where the original image and the staple position do not overlap with each other, there is no inconvenience that the image cannot be seen by the staple even if the copied sheets are stapled.

In the above example, when processing is performed in a state where the original image and the staple position do not overlap each other, it is realized by moving the original image or changing its magnification.
It may be realized by a combination of the movement and the scaling. The same applies to the processing described later.

Next, a case where the user selects the punching position confirmation mode on the display screen of FIG. 14 will be described. When the punching position confirmation mode is selected, the processing operation shown in the flowchart of FIG. 20 is performed, and therefore the description will be given with reference to this. First, it is judged whether or not the punching position confirmation key is selected (step 11),
When it is determined that the image has been selected, the image reading unit 2 performs the document reading operation by the prescan operation (step 12). The image of the original read by the image reading unit 2 is combined with the perforation position data preset as described above by the image processing unit 3 (step 13), and the combined image is displayed by the image display unit 7. And is displayed on the LCD panel 26 of the image display unit 7 (step 14).

Here, when the combined image displayed on the LCD panel 26 of the image display unit 7 does not overlap the original image and the punched position as shown in FIG. 17, the user confirms on the display screen. Just select the key. On the other hand, when the composite image overlaps the document image and the punched position as shown in FIG. 18, a message to that effect is displayed on the screen to alert the user. Therefore, the user may select the shift key or the scaling key on the display screen as necessary in order to eliminate the overlap.

Therefore, after the above-mentioned composite image is displayed, it is first judged whether or not the confirmation key is selected (step 1).
5) If it is determined that the confirmation key has been selected (step 15; Y), the image processing is not performed and the processing ends. On the other hand, when the confirmation key is not selected (step 15; N), it is determined whether the shift key is selected (step 16). As a result, when it is determined that the shift key is selected (step 16; Y), the portion where the document image and the punching position overlap each other is calculated, and the document image is shifted (moved) until they do not overlap. Parameters are set in the image reading unit 2 and the image processing unit 3 (step 17).

On the other hand, if it is determined that the shift key is not selected (step 16; N), then it is determined whether or not the scaling key is selected (step 18). As a result, when it is determined that the scaling key is selected (step 1
8; Y), a portion where the original image and the punching position overlap is calculated, a reduction ratio that does not overlap is calculated, and the obtained reduction ratio is read by the image reading unit 2 and the image processing unit 3.
(Step 19). In step 18,
If it is determined that the scaling key has not been selected (step 18; N), the process returns to step 14, and the selection of the next key is awaited while the combined image display is continued. After that, since the original can be copied in a state where the original image and the perforated position do not overlap with each other, even if the copied paper is bound by using the perforation, there is no inconvenience that the image cannot be seen due to the hole.

In the first embodiment of the present invention, the original image
Set the binding position of the recording paper for recording the image in advance,
The scanned image of the document and its set binding position
I made it possible to display this combined image.
Then, before copying, staple position or punching position
You can check the positional relationship between the binding position and the original image.
The image becomes after binding the copied paper.
It is possible to prevent the inconvenience of being damaged.

Further, the composite image displayed on the display unit is
If the binding position on the recording paper and the original image overlap,
Since a warning is given to that effect, the user must
Reliable recognition prior to copying. Also, the display shows
The composite image shown is the binding position of the recording paper and the original image.
If the images overlap, the original image does not overlap the binding position.
The original image was moved so that
-Even if you bind the paper afterwards, it is easy to see the original image.
Wear. Furthermore, the composite image displayed on the display is
If the binding position of and the original image overlap,
The magnification of the original image so that the image does not overlap the binding position.
Since it was changed, the paper binding after copying
Even if the user goes, the original image can be easily seen.

Next, a second embodiment of the present invention will be described. To explain the outline of the second embodiment,
The stapling position or punching position of the paper after copying can be set in advance, the image of the original is read, the character part is separated (extracted) from the image, and the separated character part and its setting are set. Whether or not the staple position or the punching position overlaps with each other is determined, and the quality of the positional relationship between the staple position or the punching position and the character portion in the original image can be confirmed before copying. The second embodiment has basically the same configuration as that of the first embodiment, and the operation thereof is different as follows. Therefore, this operation will be described below.

First, in the second embodiment, the staple position and the punching position are set in advance by the user, as in the first embodiment. That is, when the user presses the number "4" on the screen shown in FIG. 11, the contents of the screen are changed to the staple position setting screen as shown in FIG. 12, and the staple position can be set. Further, when the user presses the number "5" on the screen shown in FIG. 11, the contents of the screen are changed to the screen for setting the drilling position as shown in FIG. 13, and the drilling position can be set.

Next, when the user presses the position confirmation mode key 51 of the operation unit unit 5 shown in FIG. 4, the position confirmation mode is selected and the display contents of the display unit 53 of the operation unit unit 5 are as shown in FIG. Is changed to. Since there are two position confirmation modes, a staple position confirmation mode and a punching position confirmation mode, the user can select one of the modes by pressing the execution key as necessary. Now, when the user selects the staple position confirmation mode, FIG.
The processing operation shown in the flowchart of FIG.

First, it is judged whether or not the staple position confirmation key is selected (step 21). When it is judged that the staple position confirmation key is selected, the image reading unit 2 performs a document reading operation by a prescan operation (step 2).
2). When the image of the document read by the image reading unit 2 is sent to the image processing unit 3, the character portion and the photograph are separated in real time, and the separated character portion and the photograph are previously stored as described above. The process of determining the overlap with the set staple position is performed (step 2
3). The result of the overlap determination process is displayed on the display unit 53 of the operation unit 5 (step 24).

Here, when the character portion of the document and the staple position do not overlap each other, a message to that effect is displayed as shown in FIG. 23, and the user may press the confirmation key on the display screen. On the other hand, when the character portion of the document overlaps the staple position, a message to that effect is displayed on the screen as shown in FIG. 24 to alert the user. Therefore, the user may press the shift key or the scaling key on the display screen to eliminate the overlap.

Therefore, after displaying the determination result of the overlap between the character portion of the original and the staple position, it is first determined whether or not the confirmation key is pressed (step 25), and it is determined that the confirmation key is pressed. (Step 25;
Y), the process is terminated without performing image processing. On the other hand, if the confirmation key is not pressed (step 25;
N), it is determined whether or not the shift key is pressed (step 26). As a result of the determination, when it is determined that the shift key is pressed (step 26; Y), the portion where the character portion of the original image and the staple position overlap is calculated, and the original image is shifted (moved) until the overlapping state does not occur. Parameters are set in the image reading unit (scanner) 2 and the image processing unit 3 (step 27).

On the other hand, if it is determined that the shift key has not been pressed (step 26; N), then it is determined whether the scaling key has been pressed (step 28). As a result, when it is determined that the scaling key is pressed (step 2
8; Y), the portion where the original image and the staple position overlap is calculated, the reduction ratio that does not overlap is calculated, and the calculated reduction ratio is set in the image reading unit 2 and the image processing unit 3 (step 29). . When it is determined in step 28 that the scaling key has not been selected (step 28; N), the process returns to step 24, and the selection of the next key is awaited while the display of the determination result is continued. After that, since the original can be copied in a state where the character portion of the original and the staple position do not overlap, there is no inconvenience that the characters cannot be seen due to the staple even if the copied paper is stapled.

Next, the case where the user selects the punching position confirmation mode on the display screen of FIG. 14 will be described. When the punching position confirmation mode is selected, the processing operation shown in the flowchart of FIG. 22 is performed, and the description will be made with reference to this. First, it is determined whether or not the punching position confirmation key is pressed (step 31),
If it is determined that the button has been pressed, the image reading unit 2 performs a document reading operation by a prescan operation (step 32). The image of the document read by the image reading unit 2 is sent to the image processing unit 3 to separate the character part and the photograph, and the separated character part and the preset hole as described above. A process for discriminating the overlap with the open position is performed (step 33). The result of this overlap determination processing is displayed on the display unit 53 of the operation unit 5 (step 34).

Here, when the character portion of the document and the perforation position do not overlap each other, a message to that effect is displayed as shown in FIG. 25, and the user may press the confirmation key on the display screen. On the other hand, when the character portion of the document overlaps the perforation position, a message warning that is displayed on the screen as shown in FIG. 26 to alert the user. Therefore, the user may press the shift key or the scaling key on the display screen to eliminate the overlap.

Therefore, after displaying the determination result of the overlap between the character portion of the original and the punching position, it is first determined whether or not the confirmation key is pressed (step 35), and it is determined that the confirmation key is pressed. If so (step 35;
Y), the process is terminated without performing image processing. On the other hand, if the confirmation key is not pressed (step 35;
N), it is determined whether or not the shift key is pressed (step 36). As a result, when it is determined that the shift key is pressed (step 36; Y), the portion where the character portion and the punched position of the original image overlap is calculated, and the original image is shifted (moved) until it does not overlap. The parameters are set in the image reading unit 2 and the image processing unit 3 so as to allow it (step 37).

On the other hand, if it is determined that the shift key is not pressed (step 36; N), then it is determined whether the scaling key is pressed (step 38). As a result, when it is determined that the scaling key is pressed (step 3
8; Y), a portion where the original image and the punching position overlap is calculated, a reduction ratio that does not overlap is calculated, and the obtained reduction ratio is read by the image reading unit 2 and the image processing unit 3.
(Step 39). If it is determined in step 38 that the scaling key has not been selected (step 38; N), the process returns to step 34, and the selection of the next key is awaited while continuing to display the determination result. After that, since the copy of the document can be executed in a state where the character portion of the document does not overlap with the punched position, even if the copied sheet is bound using the hole, the character is not invisible due to the hole.

[0057]

According to the present invention, the binding position of the recording sheet for recording the image of the original is set in advance, the character portion in the read image of the original is extracted, and the extracted character portion and the set binding position are set. Since it is determined whether or not there is overlap, it is possible to check the positional relationship between the binding position such as the staple position and the punching position and the character part before copying. It is possible to prevent inconvenience that the part is damaged.

Further , when the judging means judges that there is an overlap between the character portion in the original image and the binding position, the warning is issued to that effect, so that the user is notified of that fact before copying. Can be surely recognized.

When the determination means determines that the character portion in the original image and the binding position overlap, the original image is moved so that the character portion in the original image does not overlap the binding position. Therefore, even if the sheets are bound after copying, the character portion can be easily seen.

When the determining means determines that the character portion in the original image and the binding position overlap, the magnification of the original image is changed so that the character portion in the original image does not overlap the binding position. Therefore, even if the sheets are bound after copying, the character portion can be easily seen.
