Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a copying machine having an image editing function, and particularly to a copying machine that can set a plurality of areas.

[Conventional technology and its problems]

In recent years, copying machines have dramatically improved copying performance and have come to be equipped with many functions such as continuous page copying, double-sided copying, binding margin creation, offset copying, and image editing copying. Image editing copying is a method of copying by specifying the range and color of a specific area of an original image, and an example thereof is shown in Japanese Patent Application Laid-Open No. 60-237469.

However, in conventional image editing and copying, only a single color can be specified in an area, and it is not possible to specify a different color for each arbitrary area.

Therefore, in order to make the colors of two areas different, 1
It was necessary to specify one area and make a first copy, and then specify that area in a different color and make a second copy, which was cumbersome and required a lot of time and effort. . Moreover, if two areas overlap each other, or if one area includes another area, there is a problem that the colors will overlap due to the two-sided copying and the image will become unclear. was.

In view of the above-mentioned problems, the present applicant has proposed a copying machine in which multiple areas can be set at arbitrary positions and a different color can be set for each area. Depending on the range of each area and the positional relationship between each area, as in the case of inclusion, the image may become unclear if the mode set for a certain area is executed as is. A problem arose.

[Technical means for solving the problem] In view of the above-mentioned problem, the present invention makes it possible to set a plurality of areas at arbitrary positions, set a different color for each area, and make it possible to set a different color for each area. The purpose is to prevent the image from becoming unclear even when it is included in the area, and the technical means for this purpose is image editing that sets the range and color of a specific area of the original image and copies it. In a copying machine having this function, an area range setting means capable of setting two or more ranges of the area, and a mode selectively set from among three or more types of modes including two types of color modes and an erase mode. mode setting means for performing the setting, and for each of the areas set by the area range setting means, the mode setting means can selectively set a mode from among three or more modes; done1
If one area is included in another area, priority is given to the included area.

[For production]

Multiple areas are specified by the area range setting means,
For each designated area, it is possible to set any mode from among three or more modes, including two types of color modes and erase mode, and one set area can be included in other areas. If the included area is selected, priority is given to the included area, and copying is performed according to the mode of that area.

This ensures that the included area does not disappear (,
Also, clear copies are made without duplication with copies in other areas.

U controls the entire system. 2nd CP
The third CPU U2O2 controls the inter-image eraser lamp 4, which will be described later, as well as image forming processes such as paper feeding, image formation, and fixing.The third CPU U2O5 controls the optical system 10, which controls the lens position and scanner speed.

Between each of the PU202 and the fourth CPU U2O4, communication lines 217,
The ROM 203 and 207 store programs necessary for control, and the RAM 206 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 inter-image eraser lamp 4 has light emitting elements 51, 51, . A certain number (60) of photosensitive drums 1 are arranged in rows and receive light from the light emitting elements 51.
This method reduces or eliminates the electric charge on the surface portion of the image so that no image is formed on that portion. Therefore, at least one light emitting element 51 emits light at a certain timing,
Or, by stopping the light emission, a specific area will be formed in that part.

FIG. 5 shows a control circuit for the inter-image eraser lamp 4. This control circuit includes a shift register 52, a latch 53, a driver 54, and a voltage variable device 55, and the second CPU U2O
The data serially output from 2 is sent to shift register 5.
2, latched at launch 53, and the second CP
The driver 54, which is turned on and off by the 5TROBE signal from U2O2, causes the light emitting element 51 to emit light according to the data. The voltage variable device 55 supplies each light emitting element 51 with a voltage at the same level as the power supply voltage Vcc, and also supplies a voltage at the same level as the power supply voltage Vcc.
Signal V specifying half erase from CPU U2O2
When receiving v, a low voltage set by the setting device 56 is supplied to each light emitting element 51.

The data from the second CPU U2O2 to the shift register 52 is created according to the size of the original 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 composed of a plurality of light emitting elements 5I, the resolution for erasing is that of 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 can be specified in the editing operation section 9.
This is done by operating 7.

First, the method of specifying these by 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. First, for area 1, zoom key 95
and the display device 72, specify the coordinates using the coordinate display units 110 to 113 and the input key 102 to input the coordinates A to D of area 1, and then set 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 manner 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 duplex 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.

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
Processing is often performed based on data received from the O5, but 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

When the iff is being copied, the control between each is what is set in lj.

Next, it is determined whether area l has not been canceled (step #105), whether coordinates A and B of area 1 are not equal (step #106), and position 5c of area 1 is determined. 11D are not equal (step #107), and if all of these are YES, proceed to the next step #108 and below to perform the processing in area l; if no, perform the processing in area 1. Jump to step #113 without performing.

In step #108, it is determined whether the coordinate ff1A of area 1 is 0 or not, and if the coordinate A is O, go to step #]09.
If the coordinate A is not O, the process advances to step #112.

In steps #I09 and #110, the flag FEDTWD and the flag FEDTAI are set in response to the fact that the position 11A of area 1 is 0. In step #111,

Steps #158 to #164 correspond to area 1, and steps #158 to #164 correspond to area 2.

In step #151, if the timer TMEDAI is set, it is counted up, and as a result,
If the timer TMEDAI ends, step #152 is executed, and if the timer TMEDAl is not set or the timer TMEDA1 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 "0", the process proceeds to step #153, and if it is "1", the process proceeds to step #156.

In step #153, the flag FEDTA1 is set to "l" to start the section of area l, and 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 #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 area outside the area is color, the same process as in step #304 described above is performed in step #306, and if it is black or erased, the process in step #308 is performed. Also, step #

FIG. 17 shows a subroutine EDWMAG (step #122 in FIG. 12) that calculates coordinate data corresponding to the horizontal magnification. This subroutine EDWMAG is used to prevent the calculated horizontal width of the specified area from becoming 0 and the area disappearing due to the calculation of the reduction ratio and rounding down when editing using the reduction ratio. processing is also performed. In this subroutine,
Steps #351 to 358 are in area l, step #3
59 to 366 are processes corresponding to area 2.

In step #351, the horizontal magnification is calculated for the data at IC in area 1, and in step #352, the same calculation is performed for the coordinates.In step #353, the results of the above calculations are equal. If they are equal, the processes from step #354 onwards 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 the result of the calculation, and the coordinate is 60 (the large value of Ji is 60).
0, which is equal to the number of light-emitting elements 51), the round-up value of the coordinate C and the round-down value of the coordinate are compared in step #356, and if the round-up value of the coordinate C is larger, the process proceeds to step #356. 357, subtract 1 from the calculated value of coordinate C, and if the rounded down value of coordinate C is larger, proceed to step #
At step 358, 1 is added to the calculated coordinate value. As a result, a correction (subtracting 1) is made to the larger of the round-up value and the round-down value, and the position of the designated area and the position of the light emitting element 51 to be controlled in the eraser lamp are corrected. The positional deviation between them is reduced.

In steps #359-366, the same processing as that performed in steps #351-358 for coordinates C, D of area 1 is performed for coordinates G, H of area 2.

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 l, 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.

If all of 4 are yes, area 2 is area 1
If area 2 is completely included in area 1, 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 1, execute steps #407 and 408. Execute.

Steps #405 and 406 are subroutines that perform processing to send data for controlling the light emitting element 51 of the inter-image eraser lamp 4 to the area 1.2, and are the same as steps #407 and 408, respectively. . That is, if area 2 is completely included in area 1, subroutine EDWDAI.

The subroutine EDWDA2 is executed in this order, and the subroutine EDWDA2 for area 2 is executed later, giving priority to area 2. 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, and the portion of area 2 that overlaps with area 1 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 l is specified as black, the rest of area 2 is specified as color, and area 2 is specified as color. Copying is performed with the outer side erased.

On the other hand, if area 2 is completely included in area l, area 2 will disappear if area l is given priority as a general rule, 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 L is specified as black, and area Copying is performed with the outer side erased.

FIG. 19 shows the subroutine ED for area 1 mentioned above.

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 1 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 step #455.457
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 then returns to the subroutine EDW of step #459.
The DON turns on the light emitting element 51 of the inter-image eraser lamp 4 for a designated area so as not to form an image in that area.These will be described in detail in FIGS. 21 to 23.

At this time, the pole switching SL of the lower developing device 6 is off), and the developing sleeve of the main developing device 5 is turned on at the same time as the developing sleeve of the lower developing device 6 is turned off. Upper and lower developing units 5.
The reason why the developing sleeves of the main developing device 5 are not turned on at the same time is to prevent the load from becoming excessively large.
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 main 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 of switching from the main developing device 5 to the lower developing device 6 is determined when the position detection sensor 43 is detected 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 L is given priority, so copying is performed preferentially using the color or erase mode specified in the range of Area L, and the area The part of Area 2 that overlaps with Area 1 will be copied using the mode specified by Area 1, which will prevent the overlapped part from being copied twice or in two colors, making the image unclear. You can prevent this from happening.

Furthermore, when area 2 is included in area 1, priority is given to area 2 regardless of the above-mentioned priority order. This prevents the images (all) from becoming unclear, and also prevents area 1 from disappearing by giving priority to area 1.

In the above-described embodiment, the color of the upper developing device 5 is red, but it may be other colors such as yellow or green.The color of the lower developing device 6 is black, but this may also be a different color. The upper and lower developing devices may be interchanged. 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.

In the above embodiment, priority is given to the mode of Area 1 of Area 1 and Area 2, but the mode of Area 2 is given priority.
In that case, if area 1 is included in area 2, priority may be given to area l. Also, it is possible to set three or more areas. In this case, if one area is included in a plurality of other areas, at least a portion of the included areas may be given priority over the other areas. Furthermore, if three or more areas are nested inside each other, the innermost area may be given top priority, and the priority may be lowered as the areas move toward the outside.

The configuration and input method of the editing operation unit 97 for inputting or specifying area coordinates and mode may be various other than those in the embodiment.

〔Effect of the invention〕

According to the present invention, when it is desired to copy two areas of a document in different colors, there is no need to repeat setting and copying the areas and colors multiple times as in the past, and operability is improved. This improves the time and effort required for copying.

Also, if the set area is included in another area, priority is given to the included area, so the image of the overlapping part of the area and area 2 (that is, the entire part of the included area) This prevents the area from becoming unclear, and also prevents the area from disappearing.
