Further, the display editor 103 has a processing / editing function for scaling image data, as will be described later. As will be described later, the warning unit 104 generates a predetermined warning sound or warning display when the binding margin set by the user while looking at the display screen of the display editor 103 affects the output image as described later. To do. The control unit 105
It is composed of a microcomputer or the like, and controls each of the above-described devices and each unit in a predetermined procedure.

FIG. 2 shows a schematic mechanical configuration of the color scanner 1 and the color printer 2 described above. FIG. 3 is an enlarged view of the periphery of the photosensitive drum and the intermediate transfer belt. The color scanner 1 forms an image of the original 3 on the color sensor 7 through the illumination lamp 4, the mirror group 5 (5-1, 5-2, 5-3) and the lens 6 to form a color image of the original. Information is read for each B (blue), G (green), and R (red) color-separated light and converted into an electrical image signal. Then, on the basis of the B, G, and R color-separated image signal intensity levels obtained by the color scanner 1, color conversion processing is performed by the image processing unit 101, and black (hereinafter referred to as BK), cyan (hereinafter referred to as BK) , C), magenta (hereinafter referred to as M),
Yellow (hereinafter referred to as Y) color image data is obtained. The color printer 2 described below
Visualize K, C, M, and Y, and superimpose them, and
Form a full-color image.

The color printer 2 has a writing optical unit 8, which converts the color image data from the color scanner 1 into an optical signal,
Optical writing corresponding to the original image is performed, and the photoconductor drum 9
To form an electrostatic latent image. Here, the writing optical unit 8
Is composed of a laser 8-1, a polygon mirror 8-2, a polygon motor 8-3, an f / θ lens 8-4, and a reflection mirror (8-5).

The photoconductor drum 9 rotates counterclockwise as shown by the arrow, but around the photoconductor drum 9, a photoconductor cleaning unit (including a pre-cleaning static eliminator) 10, a static elimination lamp 11, a charger 12, and a potential sensor 13 are provided. , BK developing device 14,
A C developing unit 15, an M developing unit 16, a Y developing unit 17, a development density pattern detector 18, an intermediate transfer belt 19 and the like are arranged. Each of the developing devices 14 to 17 has a developing sleeve (14-1, 15-1, 16-1, 17) that rotates so that the developer faces the photosensitive drum 9 in order to develop the electrostatic latent image.
-1) and the developing paddles (14-2, 15-2, 16-2, 17-) that rotate to draw up and agitate the developer.
2) and the toner concentration detection sensor of the developer (14-3, 1
5-3, 16-3, 17-3) and the like.

Next, the order of the developing operation (the order of forming the color image) will be described below by taking BK, C, M and Y as an example. However, the image forming order is not limited to this. When the copy operation is started, the color scanner 1 starts reading BK image data at a predetermined timing, and optical writing / latent image formation by laser light is started based on the image data (hereinafter, electrostatic charge based on BK image data is used). The latent image is called a BK latent image. The same applies to C, M, and Y).

In order to enable development from the front end of the BK latent image, the developing sleeve 14-1 starts rotating before the front end of the latent image reaches the developing position of the BK developing device 14 to form the BK latent image in BK. Develop with toner. Then, after that, the developing operation of the BK latent image area is continued, but the developing operation is disabled when the trailing edge of the BK latent image passes the BK developing position. This is completed at least before the leading edge of the C latent image by the next C image data arrives.

The BK toner image thus formed on the photosensitive drum 9 is transferred to the surface of the intermediate transfer belt 19 which is driven at the same speed as the photosensitive drum 9 (hereinafter, the intermediate transfer from the photosensitive drum 9). The transfer of the toner image onto the belt 19 is called belt transfer). The belt transfer is performed by applying a predetermined bias voltage to the transfer bias roller 20 while the intermediate transfer belt 19 of the photosensitive drum 9 is in contact.
In addition, on the intermediate transfer belt 19, the toner images of BK, C, M, and Y that are sequentially formed on the photosensitive drum 9 are sequentially aligned on the same surface to form a belt transfer image of four-color overlap,
Then, the batch transfer is performed on the transfer paper (recording paper). The configuration and operation of the unit of the intermediate transfer belt 19 will be described later.

On the side of the photoconductor drum 9, the BK process is followed by the C process, but the C image data is read by the color scanner 1 from a predetermined timing, and the C latent image is written by laser light writing using the image data. Form. The C developing device 15 has the BK
After the trailing edge of the latent image has passed and before the leading edge of the C latent image reaches, the developing sleeve 15-1 starts rotating to develop the C latent image with C toner. After that, the development of the C latent image area is continued,
At the time when the leading edge of the latent image passes, the development is inoperative as in the case of the BK developing device 14 described above. This is also completed before the leading end of the next M latent image reaches. In addition, M process and Y
Regarding the steps, the operations of reading the respective image data, forming the latent image, and developing are the same as those of the steps BK and C described above, and therefore the description thereof is omitted.

Next, regarding the intermediate transfer belt unit,
explain. The intermediate transfer belt 19 is stretched around a drive roller 21, a belt transfer bias roller 20, and a group of driven rollers, and is drive-controlled by a drive motor 35 as described later. The belt cleaning unit 22 is composed of a brush roller 22-1, a rubber blade 22-2, a contact / separation mechanism 22-3 from the belt, and the like. While the fourth color is being transferred on the belt, it is separated from the belt surface by the contact / separation mechanism 22-3. The paper transfer unit 23 includes a paper transfer bias roller 23-1, a roller cleaning blade 23-2, and a belt contact / separation mechanism 23-3. This transfer paper bias roller 23-1 is
Normally, it is separated from the surface of the belt 19, but when the four-color superimposed image formed on the surface of the intermediate transfer belt 19 is collectively transferred to the transfer paper, it is pressed by the contact / separation mechanism 23-3 at a timing, and this roller A predetermined bias voltage is applied to 23-1 to transfer to paper.

The transfer paper 24 is fed by the paper feed roller 25 and the registration roller 26 at the timing when the leading end of the four-color superimposed image on the intermediate transfer belt surface reaches the paper transfer position.

The movement of the intermediate transfer belt 19 is an operation method after the belt transfer of the BK toner image of the first color is completed up to the rear end portion. In this image recording apparatus, the following reciprocating motion (quick return) is performed. The scheme is done. After the belt transfer of the BK toner image is completed, the intermediate transfer belt 19 is separated from the surface of the photoconductor drum 9 to stop the forward movement, and at the same time, to return in the opposite direction at a high speed. In this return, the front end position of the BK image on the surface of the intermediate transfer belt 19 passes through the position corresponding to the belt transfer in the opposite direction, and after moving for a preset distance, it is stopped and put in a standby state. Next, when the front end portion of the toner image on the photosensitive drum 9 side reaches a predetermined position before the belt transfer position, the intermediate transfer belt 19 is restarted in the forward direction. Also,
The intermediate transfer belt 19 is brought into contact with the surface of the photosensitive drum 9 again. Also in this case, the C image is B on the surface of the intermediate transfer belt 19
The belt transfer is performed under the condition that the K image is accurately overlapped. After that, the same operation is performed to proceed to the M image process and the Y image process to obtain a belt transfer image of four colors. Subsequent to the belt transfer process of the Y toner image of the fourth color, the toner image moves forward at the same speed without returning, and the four-color superimposed toner image on the surface of the intermediate transfer belt 19 is collectively transferred to the transfer paper 24.

The transfer paper 24 on which the four-color superimposed toner images are collectively transferred from the surface of the intermediate transfer belt 19 is a paper transport unit 27.
Then, the toner image is transported to the fixing device 28 by the fixing roller 28-1 and the pressure roller 28-2, which are controlled to a predetermined temperature, and the toner image is fused and fixed to the copy tray 29 to obtain a full-color copy. The surface of the photoconductor drum 9 after the belt transfer is cleaned by the photoconductor cleaning unit 10 and uniformly discharged by the charge eliminating lamp 11. Further, the intermediate transfer belt 19 after the toner image is transferred onto the transfer paper 24 is
The cleaning unit 22 is pressed again by the contact / separation mechanism 22-3 to clean the surface.

At the time of repeat copy, the color scanner 1
And the image formation on the photosensitive drum 9 are performed at a predetermined timing after the first Y (fourth color) image process.
Proceed to the BK (first) image process for the first sheet. Further, in the intermediate transfer belt 19, after the batch transfer process of the first four-color superposed image onto the transfer paper, the second BK toner image is transferred to the area where the surface is cleaned by the cleaning unit 22. To be transcribed. After that, the operation is the same as that of the first sheet.

The transfer paper cassettes 30, 31, 32,
Transfer papers 33 of various sizes are stored in the registration roller 26 at a timing from the storage cassette of the size paper designated by the input operation unit 102 as shown in FIG.
The paper is fed and transported in the direction. Reference numeral 34 denotes a manual paper feed tray for OHP paper and thick paper. Further, 37 is an ADF (automatic paper feeder).

The above description has been made in the case of the copy mode in which four full colors are obtained, but in the case of the three-color copy mode and the two-color copy mode, for the designated color and the number of times,
The same operation as above will be performed. In the case of the single-color copy mode, only the developing device for the color is kept in the developing operation state until the predetermined number of sheets are finished, and the intermediate transfer belt 19
Drives at a constant speed in the forward direction while being in contact with the surface of the photoconductor drum 9, and the copy operation is performed while the belt cleaner 22 is also in contact with the belt 19.

Next, regarding the input operation unit 102 described above,
This will be described with reference to FIG. FIG. 4 is a plan view of the input operation unit 102. As shown in FIG. 4, when the operator selects the copy mode, the input operation unit 102 asks the apparatus according to the selected copy mode. The operation / display unit 1021 having a touch panel for responding to the contents is provided. The operation / display unit 1021 includes touch keys 1022 for entering a page continuous shooting mode and a double-sided mode, which will be described later, among the copy modes.

Further, as shown in FIG. 4, a numeric keypad 1023 for inputting the number of copies, a scaling factor, and other numerical values is arranged in the input operation unit 102, and the numeric keys 1023 bind the recording paper on which an image is recorded. You can enter the amount of money. Further, as shown in FIG. 4, the input operation unit 102 is provided with a clear / stop key 1024 for clearing the mode in the middle of operation, a start key 1025 for starting printing, and other keys.

Next, the display editor 103 described above.
Will be described with reference to FIG. FIG. 5 is a front view of the display editor. As shown in FIG. 5, the display editor 103 includes a display unit 1031 for displaying a read image and setting a binding margin on a display screen, and a reading key (hereinafter referred to as a press key) for starting reading a document. Called canky) 1032
And a cursor movement key 1033 for moving the cursor on the display screen to set the binding margin amount of the recording paper. Further, the display unit 1031 can display a cursor indicated by an arrow in the drawing and a cursor display of “x” mark as described later.

Next, the operation of the embodiment thus configured will be described below. Prior to the description of this operation, the copy mode used in this embodiment will be described. This copying mode includes a page continuous copying mode in which the left and right sides of the original are divided into half and copied onto the recording paper, and a double-sided mode in which both sides of the recording paper are copied. In the page continuous shooting mode, there are the following two modes. As shown in FIG. 6, a mode in which an image is copied from a two-page spread original onto one side of the recording paper. As shown in FIG. 7, a mode in which an image is copied from a double-sided original onto one side of the recording paper. There are three modes. As shown in FIG. 8, a mode in which two single-sided originals are copied on both front and back sides of recording paper, as shown in FIG. 9, a mode in which two-sided originals are copied on both front and back sides of recording paper, as shown in FIG. Mode to copy both sides of recording paper from the original

Next, the operation of the two page continuous shooting modes will be described with reference to the drawings. First, as shown in FIG. 6, a case of a mode in which an image is copied from a two-page spread original document to one side of recording paper will be described. In this case, the user sets the double-page spread original 3 on the original platen 3 ', and then selects a mode for performing one-sided copying from the double-page spread original by operating the input operation unit 102. Next, the prescan key 1032 arranged in the display editor 103.
When the user presses, the color scanner 1 starts scanning and the spread original 3 is read by the CCD 7.

The image signal of the read original 3 is supplied to the display editor 103, and the display screen of the display unit 1031 of the display editor 103 has two left and right pages of the two-page spread original as shown in FIG. The contents of the mode for copying to the paper are displayed. Inquiries from the device side to the user are displayed on the operation / display unit 1021 of the input operation unit 102.

After that, the process shifts to the process for setting the binding margin of the recording paper. This process will be described with reference to the flowchart of FIG. First, the user is asked whether to set the binding margin (step 1). Therefore, when the user gives an instruction to set the binding margin from the input operation unit 102, only the reference point (line) and the cursor are displayed on the display unit 1031 of the display editor 103. At 11, the display is in a state without broken lines. At this time, if the display unit 1031 outputs and displays the image of the first page and the image of the second page in different colors, the first page and the second page can be easily determined. The above-mentioned reference point is obtained by detecting the position of the document during pre-scanning and indexing the result.
Is displayed on the display unit 1031.

Next, it is determined whether or not the binding margin settings for the first and second sheets of recording paper are performed (in one batch) (step 2).
Ask the user. As a result, when the user selects and instructs to set the binding margin in an interlocking manner, the user is asked whether or not the binding margin should be set and input (step 3). Therefore, when the user selects the size input and inputs the size with the ten keys 1023 arranged on the input operation unit 102 (step 5), the length of the binding margin from the reference point is input with the ten keys 1023. Editor 10
The cursor displayed on the display unit 1031 of No. 3 moves, and a broken line appears as shown in FIGS. On the other hand, when the user does not select the above-mentioned dimension input and moves with the cursor movement key 1033 arranged in the display editor 103 (step 6), simultaneously with pressing the cursor movement key 1033, the display editor 10
A broken line is displayed on the display unit 1031 of No. 3, and the broken line moves together with the cursor (see FIGS. 11A and 11B).

Next, the device (control unit 105) judges whether or not there is an error in the input from the user (step 7), and if there is an error, the process returns to step 1. On the other hand, if there is no mistake, it is determined whether the binding margin set as described above does not affect the image output on the recording paper (step 8).

As a result, as shown in FIG. 11B, when the set binding margin is overlaid on the image and it is determined that the image is affected, the warning unit 104 generates a warning sound to that effect. , Or a warning is displayed (step 9). In this case, the user is asked whether to reduce the image (step 10). Therefore, when the user gives an instruction to reduce the image, the display editor 103 side displays
As shown in (b), the reduction ratio is calculated so that the binding margin and the image do not overlap (step 11), and the reduced image is displayed on the display unit 1031 of the display editor 103 (step 12). The image can be reduced by the user. When the user does not select the reduction of the image, the image is displayed as it is as shown in FIG. 11B (step 12).

On the other hand, when it is determined in step 8 that the set binding margin does not affect the image output on the recording paper, the user is asked whether or not to enlarge the image (step 13). Therefore, when the user instructs to enlarge the image, the display editor 103 side
As shown in FIG. 2 (c), the enlargement ratio is calculated so that the binding margin and the image do not overlap (step 14), and the enlarged image is displayed on the display unit 1031 of the display editor 103 (step 12). Note that the user can arbitrarily input the enlargement of the image. When the user does not select the enlargement of the image, the image is displayed as it is as shown in FIG. 11A (step 12).

In the above description, the case where the binding margins of the first and second sheets of recording paper are set in conjunction with each other has been described. However, in response to the question of whether or not to perform the binding margin in step 2 above, the user can select and instruct to set the binding margin independently without interlocking the binding margin.
When the user selects that the binding margin should be set independently, the screen is designated by the cursor (step 4), and (b) can be selected by moving the cursor on the screen shown in FIG. 11, for example. After that, if the binding margins of the first page and the second page are set independently by the same procedure as described above, the binding margin of only the recording sheet of the second page can be set large as shown in FIG. it can.

Next, as shown in FIG.
The case of the mode of copying on one side of each sheet of recording paper will be described below. In this case, an ADF (automatic paper feeder) 37 is required as shown in FIG. In this case, when the ADF 37 conveys the first page of one original 3 toward the original table 3, the color scanner 1 starts scanning and reads the original 3. The read image signal of the first page is supplied to the display editor 103.

Next, when the ADF 37 reverses the front and back of the original and conveys the second page of the original 3 toward the original table 3 ', the color scanner 1 starts scanning and reads the original 3. The read image signal of the second page is supplied to the display editor 103. In the display unit 1031 of the display editor 103, as shown in FIG.
The contents of the mode for copying two 2-sided pages onto a single-sided recording sheet are displayed. After that, the user sets the binding margin of the recording paper, which is similar to the above-described case of copying from the two-page spread original on one side, and therefore the description thereof is omitted here.

In the above description, the case where the two images read by the color scanner 1 are simultaneously displayed on the display unit 1031 of the display editor 103 to set the binding margin is described. You may make it display independently. In this case, the display of the image can be enlarged, and thus the work for setting the binding margin can be easily performed and the confirmation work can be facilitated.

Next, the operation of the above-mentioned three modes of the double-sided mode will be described with reference to the drawings. First, as shown in FIG. 8, a case of a mode in which an image is copied from two single-sided originals to both sides of one recording sheet will be described. In this case, when the ADF 37 sets two originals or the user manually puts the originals on the original table 3'and presses the prescan key 1032, the color scanner 1 starts scanning and the originals are scanned. To read.

The read image signal of the original 3 is supplied to the display editor 103, and the display unit 1031 of the display editor 103 displays the contents of the mode for copying the left and right pages of FIG. At the same time, the binding margin setting screen is displayed. At the time of this display, it is preferable to change the color of the display on the front side and the color on the back side because they can be easily distinguished.

Next, the process proceeds to a process for adjusting the binding margin. This adjustment is the same as in the above-described single-sided copy mode from the two-page spread original (see FIG. 6), but in the binding margin direction (binding margin). Position) is different as described below.
Hereinafter, this processing will be described with reference to the flowchart in FIG. When shifting to the binding margin adjustment, the user is first asked whether to set the binding margin (step 2).
1). Therefore, when the user gives an instruction to set the binding margin from the input operation unit 102, the display editor 1
On the display unit 1031 of No. 03, only the reference point (line) and the cursor are displayed, and this display is a display without a broken line in FIG. The above-mentioned reference point is detected and indexed for the document position during prescanning, and the result is displayed on the display unit 1031 of the display editor 103.

Next, the user is asked whether the setting of the binding margin is the size input (step 22). Therefore, in the case where the user selects the size input and inputs it with the ten keys 1023 arranged on the input operation unit 102 (step 23),
When the length of the binding margin from the reference point is input with the ten keys 1023, the cursor displayed on the display unit 1031 of the display editor 103 moves, and a broken line appears as shown in FIGS. 13 (a) and 13 (b). On the other hand, in the case where the user does not select the above-mentioned dimension input and performs the input by the cursor movement key 1033 arranged in the display editor 103 (step 24), the display editor 103 is pressed at the same time when the cursor movement key 1033 is pressed. Display unit 1031
A broken line is displayed on the screen, and the broken line moves with the cursor (see FIGS. 13A and 13B).

Next, the device (control unit 105) judges whether or not the input from the user is incorrect (step 2).
5) If there is an error, return to step 21. On the other hand, if there is no mistake, it is determined whether or not the binding margin set as described above affects the image output on the recording paper (step 26). As a result, as shown in FIG. 13B, if the set binding margin is overlaid on the image and it is determined that the image is affected, the warning unit 104 issues a warning sound to that effect or a warning. Display (Step 2)
7).

In this case, the user is asked whether to reduce the image (step 28). Therefore, when the user gives an instruction to reduce the image, the display editor 1
On the 03 side, as shown in FIG. 14B, the reduction ratio is calculated so that the binding margin and the image do not overlap (step 2
9), the reduced image is displayed on the display editor 10
No. 3 is displayed on the display unit 1031 (step 30). The image can be reduced by the user. When the user does not select the reduction of the image, the unreduced image is displayed as it is as shown in FIG. 13B (step 30).

On the other hand, if it is determined in step 6 that the set binding margin does not affect the image output on the recording paper, the user is asked whether or not to enlarge the image (step 31). Therefore, when the user gives an instruction to enlarge the image, the display editor 103 calculates the enlargement ratio so that the binding margin does not overlap the image (step 32), and the enlarged image is displayed on the display editor 103. It is displayed on the section 1031 (step 30).
When the user does not select the enlargement of the image, FIG.
As shown in (a), the image is displayed as it is (step 30). The display editor 103 displays the left and right pages of FIG. 8 as a mode for copying two sheets on one side and a binding margin setting screen.
