Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a copying machine having an image editing function and a simulcolor function.

[Conventional technology and its problems]

In recent years, copying machines have dramatically improved their copying performance and have come equipped with many functions such as continuous copying, double-sided copying, binding offset copying, offset copying, and image editing copying. Among these, image editing copying involves specifying the range and color of a specific area of an original image to perform copying, and an example thereof is shown in Japanese Patent Laid-Open No. 60-237469.

The present applicant has proposed a copying machine that has an image editing function in which two areas can be set and a different color can be set for each area. This image editing function automatically performs two copying operations in the order of areas with a single operation, allowing you to copy different colors in any area on a single sheet of copy paper, making it easy to edit and copy originals. It has the advantage of being possible.

In addition, the present applicant has developed a method for forming multicolor images in one copying operation (one shot) by switching and activating multiple developing devices during one scanning operation by a scanner. We are proposing a copying machine with a simultaneous color function. Copying using this simulcolor function (referred to as simulcolor copying or simply simulcolor) allows, for example, copying the right and left pages of a book, the right and left sides of a drawing, or two originals at the same time on one sheet of copy paper. The advantage of this method is that it is possible to make two-color copies on one sheet of copy paper by dividing it into two parts, such as for each original, and that it can be done in one copying operation, making it easy to operate and reducing time and labor. have.

However, in a copier that has both the image editing function and the simulcolor function as described above, when both functions are selected at the same time, the color set in the area or outside the area by the image editing function and the simulcolor A problem arises as to how to handle cases where the color is different from that set by the function, or when two or more areas are set to different colors by the image editing function.

[Technical means for solving the problem] In view of the above-mentioned problem, the present invention aims to perform processing without contradiction when the image editing function and the simulcolor function are selected at the same time, and provides a technology for that purpose. The means include an image editing function that sets the range and color of a specific area of the original image and copies it;
A copying machine having a simulcolor function for copying multiple colors by switching between a plurality of developing devices during one copying operation, and when the image Iff collection function and the simulcolor function are selected at the same time. Preferably, the color set by the simultaneous color function is given priority over the color set in the area by the image editing function when copying is performed.

[For production]

If the color set in the area or outside the area by the image editing function is different from the color set by the simulcolor function, copying will be performed using the color set by the simulcolor function, and if two or more If the areas are set to different colors, copying will be performed using the set color using the simulcolor function regardless of those colors.

The PU202 controls the inter-image erase 4 lamp 4, which will be described later, and also controls the image forming process such as paper feeding, image formation, and fixing.The third CPU U2O5 controls the optical system, such as the position of the lens and the speed of the scanner. 10 controls are performed. 4th CPU

Between each of Pυ202 and the fourth CP U2O4, in addition to the aforementioned serial communication, a communication line 217.
ROM2O3 and 207 store programs necessary for control, and RAM2O6 stores data and programs as necessary.

FIG. 4 is a diagram for explaining the operation of erasing a specific area or outside the area on the surface of the photoreceptor drum 1 using the inter-image eraser lamp 4.

The image-to-image eraser lamp 4 has light-emitting elements 51, 51, which are made up of a large number of LEDs, set at a constant position in the axial direction of the photosensitive drum 1 (vertical axis direction in FIG. 44), that is, in the width direction of the copy paper. A certain number (60 pieces) of P are arranged in - columns,
This is to reduce or eliminate the charge on the surface portion of the photoreceptor drum 1 that receives light due to the light emitted from the light emitting element 51, so that no image is formed on that portion. Therefore, when at least one light emitting element 51 emits light or stops emitting light at a certain timing, a specific area is formed in that portion.

FIG. 5 shows a control circuit for the inter-image eraser lamp 4. This control circuit includes a shift register 52, a circuit 53, a driver 54, and a voltage variable device 55.
The data serially output from shift register 5
2, is latched by the latch 53, and is input to the second CPU 2.
The driver 54, which is turned on and off by the 5TRoBE signal from 02, causes the light emitting element 51 to emit light according to the data. The voltage variable device 55 applies a power supply voltage V to each light emitting element 51.
In addition to supplying the same level of voltage as cc, the second CP
When receiving the signal Vv specifying half erase from U2O5, a low voltage set by the setting device 56 is supplied to each light emitting element 51.

The data from the second CPU U2O5 to the shift register 52 is created according to the size of the document or the range (coordinates) and mode (color or erase) of the image editing area, which will be described later, and will be explained in detail in the flowchart later. It is controlled by various control timers and flags so that it is output at appropriate timing.

Since the inter-image eraser lamp 4 is made up of a plurality of light emitting elements 51, the resolution for erasing is one light emitting element 5.
1 (approximately equal to the pitch P of the light emitting elements 51), and therefore, for example, when the specified range in the width direction of the area by image editing or the calculated value in the width direction by the reduction magnification is smaller than this pitch P. is at least 1
Special processing is performed to secure the pitch and prevent the area from disappearing (see Figure 17).

Next, image editing and copying will be explained.

Image editing copying involves copying one or two designated areas within a document and the outside of those areas in a designated mode (black, color, or erase). The number of areas, range, and mode are specified by operating the editing operation section 97.

First, the method of specifying these items using the editing operation unit 97 will be explained with reference to FIG. 45. By pressing the editing key 101, the range and mode of each area can be set. 95
Specify numerical values using the display device 72, specify the coordinates using the coordinate display units 110 to 113 and the input key 102, input the coordinates A-D of area 1, and then change the mode of area 1. The designation is made by pressing any of the black key 104, color key 105, or erase key 106.

Next, for area 2, coordinates E-H and mode are input and specified in the same way as for area 1. For outside the area, specify only the mode.

When specifying only one area, press the cancel key 103 without specifying the coordinates of area 1 or area 2, and cancel one of the areas.

In FIG. 45, black is designated for area 1, color is designated for area 2, and erase is designated for outside the area, and both areas are set so that they do not overlap with each other. When the print start key 71 is pressed in this state, only the area 1 portion is copied in black onto the copy paper fed from either paper feed section 20 or 22, and this is temporarily transferred to the dubrex device 31.
The paper is then re-fed from there and only area 2 is copied in color (red), resulting in two areas being copied in their designated colors. Note that the case where area 1 and area 2 overlap will be described in the explanation of the flowchart in FIG. 18.

Next, simulcolor will be explained.

As mentioned above, simultaneous color prints two copies in one copy operation.
In the simul color of this embodiment, the image of one document is formed by pressing the lever 41 in the scanning direction of the scanner 11. The image is divided by position, and the first half is copied in color (red) and the second half is copied in black.

It is also possible to specify this simul color and the above-mentioned image editing copy at the same time. In this case, if the color of each area specified by image editing differs from the simul color, this will be ignored and the mode will be set to erase mode. Areas that did not exist will be copied using simulcolor. In other words, in this case, priority is given to simulcolor in specifying colors and copying onto copy paper, and two-color copying is performed in - number of copying operations.

FIG. 48 shows a copy made by specifying the area range and mode explained in FIG. 45 through image editing, and specifying simultaneous color. The colors are different on the left and right sides of the figure with the position of the lever 41 as the boundary, with area 1 being reproduced in red and area 2 being reproduced in black.

FIG. 49 shows a copy made by specifying an overlapping area by image editing and specifying simultaneous color. With the position of the lever 41 as the boundary, the right side is reproduced in red and the left side is reproduced in black.

Next, the processing procedure of the copying operation will be explained in detail according to the flowcharts shown in FIGS. 8-41.

First, it is determined whether or not to perform copying by image editing based on the data received from the first CP U2O5 (step #41). If yes, the process from step #42 onwards is performed. Note that the second CP U2O5 U2
Although processing is often performed based on data received from the O5, hereinafter, the data received from the first CPU 201 may be referred to as input data.

In step #42, it is determined whether or not an image of the editing area is being created. If the image is being created, the process advances to step #43; if not, the process advances to step #46. In step #43, the process branches to each subroutine depending on the contents of status code 5CEDIT that controls editing copying. Step #4

1”.

Next, it is determined whether or not area 1 has been canceled (step #105), whether coordinates A and B of area 1 are not equal (step #106), and coordinates C and C of area 1 are determined. Judgment is made as to whether or not the coordinates are not equal (step #107). If all of these are yes, proceed to the next step #108 and below to perform processing in area 1; if no, processing in area 1 is performed. Jump to step #113 without performing.

In step #108, it is determined whether or not the coordinate A of area 1 is O. If the coordinate A is 0, the process proceeds to step #109, and if the coordinate A is not O, the process proceeds to step #112.

In steps #109 and #110, the coordinate A of area 1 is O
In response to this, the flag FEDTWD and the flag FEDTAI are set. In step #111, the value obtained by calculating the magnification in the vertical direction (sub-scanning direction) on the data of coordinate B of area 1 is set to the timer TMED for controlling area 1.

Step #121 is a subroutine that initializes a line memory for editing control, and step #122 is a subroutine that calculates coordinate data in accordance with the magnification in the G [direction, the details of which will be described later.

In step #123, the state of the flag FEDTWD is determined, and if the flag FEDTWD is "l", the flag FEDTWD is cleared in step #124 to avoid repeating the same process twice, and then in step #125, A subroutine EDPRIQ is executed to determine the priority order between area 1 and area 2 and to actually create editing eraser data. Flag FEDTWD is “0”

Step #126 is a subroutine that performs site erasing in accordance with the magnification and paper size, in addition to the above-mentioned editing copy. In step #127, the status code 5CEDIT for edit copy control is updated to "1".

Figure 13 shows that the status code 5CEDIT is “1”.

8 to 164 are processes corresponding to area 2.

In step #151, if the timer TMEDA1 is set, it is counted up, and as a result,
If the timer TMEDAI ends, step #152 and subsequent steps are executed, and if the timer TMEDAl is not set or the timer TMEDAI does not end, the process jumps to step #158.

In step #152, the state of the flag FEDTAI is determined, and if the flag FEDTAI is r
In step #153, the flag FBDTA1 is set to "1" to start the section of area 1. In step #154, the flag FEDTWD is set to start the editing process. In step #155, the data at coordinate A is subtracted from the data at coordinate B in area 1, an operation corresponding to the vertical magnification is performed on this, and the resulting value is set in timer TMEDAI.

In step #156, the flag FEDTAI is cleared because the section of area l has ended. In step #157, the flag FEDTWD is set to start the editing process.

FIG. 16 is a flowchart of the subroutine EDINIT for initializing the line memory for eraser control.

In step #301, it is determined whether or not the mode is simulcolor copy mode. If it is not simulcolor copy mode, the color of the developer used is determined in step #302, and if it is black, the process proceeds to step #303; If the color is , proceed to step #305. In step #303, the mode outside the area is determined, and if the outside of the area is black, data is set to turn off all the inter-image erasers in step #304. If the area outside the area is a color other than black or erased, data is set to turn on all the inter-image erasers in step #308 so that the image is erased.

In step #305, the mode outside the area is determined. If the outside area is color, the same process as step #304 described above is performed in step #306, and if it is black or erased, the process in step #30H is performed. Also, step #

FIG. 17 shows a subroutine EDWMAC (step #122 in FIG. 12) that calculates coordinate data in accordance with the horizontal magnification. This subroutine EDWMAG
Now, when editing using the reduction magnification, there is also a process to prevent the area from disappearing because the calculated value of the horizontal width of the specified area becomes O due to the calculation of the reduction magnification and rounding down. It will be done. In this subroutine, steps #351 to #358 are placed in area 1;
359 to 366 are processes corresponding to area 2.

In step #351, a horizontal magnification is calculated for the data at coordinate C in area l, and in step #352, a similar calculation is performed for the coordinate. In step #353, it is determined whether or not the results of the above calculations are equal. If they are equal, the processes from step #354 onward are executed to ensure the minimum width of area 1.

In step #354 and step #355, the minimum and maximum values of the coordinates are checked, and the coordinate C is not 0 as a result of the calculation, and the coordinate C is 60 as the result of the calculation (the maximum value is 60).
If not (this is equal to the number of light emitting elements 51), the round-up value of coordinate C and the round-down value of coordinate coordinate are compared in step #356, and if the round-up value of coordinate C is larger, step #357 Subtract 1 from the calculated value of coordinate C, and if the rounded down value of the coordinate is larger, proceed to step #3
At step 58, 1 is added to the calculated coordinate value. by this,
Correct the larger of the round-up value and round-down value (
1) is performed to reduce the positional deviation between the position of the designated area and the position of the controlled light emitting element 51 in the eraser lamp.

In steps #3S9-366, the same processing as that performed in steps #351-358 for coordinates C, D in area 1 is performed for coordinates G, H in area 2.

FIGS. 50a to 50c are diagrams for explaining the above-mentioned correction processing. Figure 50a shows the set area 1 and area 2.
The vertical axis in Figure 0, which shows the part that is not erased by the inter-image eraser lamp 4 when making a same-size copy of A scale is attached to each pitch. For example, area 1 is not erased because the light-emitting elements 51 corresponding to the scales 35 and 36 are turned off at an appropriate timing as a result of calculation from the input coordinates C and D.

However, when this is a 50% reduced magnification copy, by simple rounding, the calculated values for the coordinates C and D are both 33 on the scale, as shown in Figure 50C.
If there is no light emitting element 51 to be turned off (as a result, the inter-image eraser lamp 4 is not controlled and area 1 disappears), if the above-mentioned correction process is performed, rounding is performed as shown in FIG. 1 of the light emitting element on the side of the coordinate C
The individual lights are turned off, and area 2 is prevented from disappearing.

FIG. 18 is a flowchart of a subroutine EDPRIO for determining the priority order between area 1 and area 2 and actually creating editing eraser data. This subroutine EDPRIO determines the overlapping relationship between area 1 and area 2, and if area 2 is completely included in area 1, priority is given to area 2 to prevent area 2 from disappearing, and other areas are In this case, processing is performed to give priority to area 1.

In steps #401 to #404, each coordinate A of area 1,
B, C, D and each coordinate of area 2 E, F, G.

Compare the size relationship with H, and step #401 to #40
If all of 4 are yes, area 2 is area 1
If it is completely included in area I, execute steps #405 and 406, and if any of steps #401 to 404 are negative, that is, if area 2 extends even slightly from area l, execute steps 4407 and 408. do.

Steps #405 and #406 are subroutines for setting data for controlling the light emitting element 51 of the inter-image eraser lamp 4 for areas 1 and 2, respectively, and are the same as steps #9407 and 408, respectively. That is, if area 2 is completely included in area 1, subroutine EDWDAI, subroutine EDWDA
The subroutine E for area 2 is executed in the order of
When DWDA2 is executed later, area 2 is prioritized, and if area 2 protrudes even slightly from area 1, the reverse is true.

As a result, Area 1 is given priority as a general rule.
Copying is performed preferentially according to the color or erase mode specified in the range of , and the portion of area 2 that overlaps with area l is copied according to the mode specified by area 1.

For example, as shown in Fig. 46, if area 1 is specified as black, area 2 as color, and the area outside the area is specified as erase, all of area 1 is specified as black, the rest of area 2 is specified as color, and area 2 is specified as erase. Copying is performed with the outer side erased.

On the other hand, if area 2 is completely included in area 1, if area l is given priority as a general rule, area 2 will disappear, so area 2 is given priority as an exception.

For example, as shown in FIG. 47, if area 1 is specified as black, area 2 is specified as color, and areas outside the area are specified as erase, all of area 2 is specified as color, the rest of area 1 is specified as black, and area 2 is specified as black. Copying is performed with the outer side erased.

FIG. 19 shows the subroutine ED for area 1 mentioned above.
It is a flowchart of WDAI.

In step #451, the state of the flag FEDTAI is determined, and if the flag FEDTAI is set to "1", the processing from step #452 onwards is performed, and the flag FEDTAI is set to "1".
If I is "0", the process returns without performing these processes.

In step #452, it is determined whether or not the mode is simulcolor copy mode. If it is not simulcolor copy mode, the color of the developing device used is determined in step #453, and if it is black, the process proceeds to step #454; If the color is , proceed to step #456. In step #454, the mode of area 1 is determined. If area l is black, subroutine EDWDOF of step #455 is executed, and if area 1 is a color other than black or erase If so, subroutine EDWDON of step #459 is executed. In step #456, the mode of area 1 is determined. If area 1 is color, the same subroutine EDWDOF as in step #455 described above is executed in step #457, and if it is black or erased, subroutine EDWDON in step #459 is executed. Execute. Also, if it is the simultaneous color copy mode in step #452, the mode of area 1 is determined in step #458, and the area 1 copy mode is determined in step #458.
If it is erased, subroutine E of step #459
DWDON is executed, and if it is black or color, subroutine EDWDOF of step #457 is executed.

Subroutine EDWDOF of steps #455 and 457
performs processing to turn off the light emitting element 51 of the inter-image eraser lamp 4 for the specified area to form an image of that area, and executes the routine EDW in step #459.
The DON turns on the light emitting element 51 of the inter-image eraser lamp 4 for the designated area and performs processing so as not to form an image in that area. These will be explained in detail in FIGS. 21 to 23.

At the same time as charging by the charger 3, the developing sleeve and pole switching SL of the normal developing device 6 are turned on, and the exposure lamp 12 is turned on. According to 2
After each exposure is completed, the charging and pole switching SL are turned off after a certain period of time, and after the pole switching SL is turned off, the developing sleeve is turned off.

FIG. 43 is a time chart when copying in red (color) is performed, that is, mainly for the normal developing unit 5. At the same time as charging, the developing sleeve of the normal developing unit 6 is turned on (
At this time, the polar switching SL of the normal developing device 6 is off), and the developing sleeve of the normal developing device 5 is turned on at the same time as the developing sleeve of the normal developing device 6 is turned off. Upper and lower developing units 5.
The reason for not turning on the developing sleeves 6 at the same time is to prevent the load from becoming excessive.
The developing sleeve is turned off after a certain period of time after two exposures by the exposure lamp 12 are completed, which is enough time for the latent image resulting from the exposure to reach the position of the regular developing device 5.

FIG. 44 is a time chart when simultaneous color copying is performed, that is, when two-color development of red and black is performed in one copying operation. The timing for switching from the normal developing device 5 to the normal developing device 6 is determined when the position detection sensor 43 is activated by the lever 41 in the middle of scanning.
It is taken from the signal output by detecting the position of.

According to the embodiment described above, in image editing and copying, area l
It is possible to specify two areas, area 2 and area 2, and for each area, it is possible to specify any mode from two types of colors, black and color, or three types of modes: erase. . Therefore, when you want to copy two areas in a document in different colors, there is no need to repeat setting and copying the areas and colors multiple times as in the past.
Operability is improved, reducing the time and effort required for copying, and copying errors are reduced, reducing wasteful consumption of copy paper and toner.

In addition, when Area 1 and Area 2 overlap, the mode of Area 1 is given priority, so copying is performed preferentially using the color or erase mode specified in the range of Area 1, and the area The parts of 2 that overlap with area 1 should be assigned to area 1.

Copying will be performed according to the specified mode.
Copying twice or in two colors in the overlapping area can be prevented, and the image can be prevented from becoming unclear.

In the above embodiment, if the color set in the area or outside the area by the image editing function is different from the color set by the simultaneous color function, copying is performed with the color set by the simultaneous color function, and the image is If two or more areas are set to different colors by the editing function, copying is performed in the color set by the simulcolor function regardless of those colors. Further, if the erase mode is set in the area or outside the area by the image editing function, that part will be erased even if the simultaneous color function is selected.

In other words, if the simultaneous color copy mode is set, parts that conflict with the colors set by image editing will be ignored and copied, and parts that have been erased by image editing will be copied. Copying is performed with priority given to the user, thereby preventing the copying from becoming impossible, and copying is performed in a state as close as possible to the copying conditions set by the user.

In the above embodiment, the color of the primary tester 5 is red, but other colors such as yellow or green may be used.Although the color of the regular tester 6 is black, it may also be other colors. You can also use it as The upper and lower developing devices may be interchanged, and although the number of developing devices is two, it may be three or more. In that case, four or more types of modes can be specified.

Moreover, various structures can be adopted for the developing device. The configuration of the editing operation section 97 and the manual method for manually specifying the coordinates and mode of the area may be various other than those in the embodiment.

〔Effect of the invention〕

According to the present invention, if the color set in the area or outside the area by the image editing function is different from the color set by the simulcolor function, copying is performed using the color set by the simulcolor function, and the image editing function If two or more areas are set to different colors by
Since copying is performed in the color set by the simulcolor function regardless of those colors, processing can be performed without contradiction when the image editing function and the simulcolor function are selected at the same time.
