Abstract

PURPOSE:To deal with diversification of cover mode by providing a controller which switches a developing device in specified timing in th middle of a single copying action in a state where the cover mode is set. CONSTITUTION:This device is provided with an automatic document feeding device 10, at least two developing means 22a and 22b which respectively perform a developing action in different color, and a control means which controls the actuating timing of two or more developing means in one copying action by mutually relating to them so that a specified area may be developed in a specified color. By commanding the copying action after the binding mode is set in a state where a document area is divided into plural virtual areas and a developing color is specified for the respective areas, the preparation of the copying action required for the set cover mode is performed previous to the copying of a final document(document of a cover). When the document of the cover is set at a scanning position, the copying action that the respective areas are developed in the specified colors is performed to the document of the cover. Thus, the copying action in the cover mode is fully automatically performed.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a copying apparatus, and more particularly to an apparatus that can distinguish a copy of a cover document from copies of other documents (content documents).

[Conventional technology]

2. Description of the Related Art Copying machines have been provided that can continuously copy a series of original documents by automatically feeding the series of original documents onto a document table glass using an automatic document feeder (ADF). In addition, in the copying machine described above, the final original (the original that is last fed onto the original platen glass) is used as a cover original, and a copy paper (for example, color paper) that is different from other originals (content originals) is used. A device for copying is provided (manufactured by Nyaap, 5F-8500).

[Problems to be solved by the invention]

There is a demand for diversification of cover modes (modes in which a copy of a cover document is copied in such a way that it can be distinguished from copies of other documents). That is, the copy of the cover manuscript and the copy of other manuscripts are separated by type of copy paper (such as the Sharp 5F-8500 mentioned above).
For example, there is a desire to be able to differentiate by other methods rather than by paper quality. There is also a demand for setting the cover mode with simple key operations, and there is also a demand for fully automatic copying operations under the cover mode. The present invention aims to meet the above requirements.

[Means to solve the problem]

The copying apparatus of the present invention includes means for feeding originals into sequential scanning positions, means for distinguishing between a cover original and other originals;
At least two developing means each performing a developing operation in a different color, an input means for dividing a document image into a plurality of virtual regions and specifying a developing color for each region, and an input means for commanding a cover mode. When the cover mode is commanded, the operation timings of two or more developing means are controlled in relation to each other during one copying operation for the cover document, so that the specified area is The image forming apparatus has a control means for developing the image in color, and scans the image of the original at the scanning position to form a copy image. The cover document is identified from other documents, for example, as the last document to be fed to the scanning position. A mode in which a designated area is developed in a designated color by controlling the operation timings of two or more developing means in relation to each other during one copying operation is called a simultaneous copying mode. This will be explained in detail in Examples.

[Effect]

After the document area is divided into a plurality of virtual areas, a development color is specified for each area, and the cover mode (cover mode 1 in the embodiment) is set, when a copying operation is commanded, the cover image is When the original is set at the scanning position, a copying operation is performed for the cover original to develop each area in the designated color.

【Example】

The present invention will be explained in detail below. [1] Configuration of the copying apparatus First, the configuration of the present copying apparatus will be explained with reference to FIGS. 1, 3, and 4. As shown in FIG. 1, this copying apparatus has a configuration in which an automatic document feeder (ADF>10) is placed on the copying machine main body 20. A document set with its side facing down is placed on the CPU 41 (
In response to the control signal from the top layer (Fig. 4),
The documents are sequentially fed onto the document table glass 26 of the copying machine main body 20 along the path indicated by the broken line arrow a, and after the scanning of the document is completed, the documents are fed onto the paper output tray 13 along the path indicated by the broken line arrow b→C-d. It is a device for discharging. In the above, the original set on the original tray 11 is detected by the original sensor IIS, and the CPL on the ADF side is 4.
5 (FIG. 4), and then transmitted to the CPU 41 on the main body side. Further, the original on the original platen glass 26 is
The document sensor 125 installed near the bottom surface of the document sensor 125 detects the document sensor 125 and inputs the document sensor 125 to the CPU 41 on the main body side. Note that the fact that the ADF 10 is connected to the copying machine main body 20 can be detected by, for example, the ADF sensor 10s. The copying machine main body 20 is a device that performs copying processing using an electrophotographic method. That is, an original positioned on the original table glass 26 is exposed and scanned in the direction of the broken line arrow X by a scanning optical system (not shown), and the reflected light image is transferred to the photoreceptor drum 21 which is charged in a negative manner and rotates at a constant speed. An electrostatic latent image is formed on the surface of the photoreceptor drum 21, and after being developed with toner by the second developing device 22b or the first developing device 22a, a predetermined image is formed. This is a device that transfers images onto copy paper that is fed at a specific timing, and then fixes the images. On the photosensitive drum 21, U is an exposure position, V is a development position of the first developer 22a, and W is a development position of the second developer 22b. Under the simultaneous copy mode settings described below,
Both the second developer 22b and the first developer 22a are used. Note that asl is a sensor for detecting that the first developing device 22a is set, and as2 to as4 are sensors for generating a color code corresponding to the toner color of the first developing device 22a. Similarly, bsl is the second
This is a sensor for detecting that the developing device 22b is set, and bS2 to bs4 are sensors for generating a color code corresponding to the toner color of the second developing device 22b. When the manual paper feed port is selected as the paper feed port, the copy paper is transferred from the manual paper feed section 27 to the transfer section (g photo drum 21 and transfer charger (not shown) along the path indicated by the broken line arrow g-j). The paper is fed to the transfer position (between the two) and subjected to transfer processing. Further, when the upper paper feed port is selected, the paper is fed from the upper paper feed cassette 28 to the transfer section along the path indicated by the broken line arrow h-j, and is subjected to the transfer process. In addition, when the lower paper feed slot is selected, the broken line arrow l is displayed from the lower paper feed cassette 29
The paper is fed to the transfer unit along the path -J and subjected to transfer processing. Note that after the transfer process, the fixing device 23 is
The sheet is conveyed to the printer, undergoes a fixing process, and is then discharged onto the paper discharge tray 24 along the path indicated by the broken line arrow β. At the bottom of each of the above paper feed cassettes) 28 and 29,
The presence or absence of copy paper in each cassette, the type of cassette (cover cassette or regular cassette), and
Sensor groups 28s and 29s are installed to detect the size of the stored copy paper, and these detection signals are input to the main CPU 41, respectively. The manual paper feed section 27 also includes a sensor 27 that detects paper to be inserted.
S is installed. The sensor group 28S includes sensor groups 28S1 to 28s4 for generating codes corresponding to the copy paper size and cassette type, and a sensor 28s5 for detecting the presence or absence of copy paper. Also,
The sensor group 29S is also the same sensor group 29S1-2 as above.
9S4 and sensor 29S5:). On the other hand, an operation panel 50 shown in FIG. 3 is installed on the upper surface of the copying machine main body 20. As shown in FIG. On the operation panel 50, there are a print key 51 for commanding the start of a copying operation, a group of numeric keys 52 for inputting numerical values, a paper feed selection key 54 for selecting a copy paper feed port, and a cover mode selection key. Various key switch groups such as a cover mode key 55 for selecting a developing color and a color selection key 56 for selecting a developing color are arranged, and operation input signals of each key switch are input to the main body CPU 41, respectively. Further, on the operation panel 50, in addition to a display section 53 that displays numerical values such as the number of copies, a group of LED elements are arranged to display the mode setting status, etc., and these can be turned on or off.
The blinking is controlled by a signal from the main CPU 41. That is, 55a to 55c are LED elements that light up to indicate the selected state of cover mode 1 to cover mode 3, respectively. Further, 54a to 54d respectively indicate the paper feed port automatic selection mode, the upper paper feed port selection state, and the lower paper feed selection state 1.
This is an LED element that lights up to indicate the manual paper feed selection state. Further, 54h to 54n are LED elements that light up to indicate the size of the copy paper stored in the paper feed cassette of the selected paper feed port, respectively. Further, 54W is an LED element that blinks to warn when no copy paper is stored in the paper feed cassette of the selected paper feed port. Also, 5
6a to 56e are LED elements that each light up to indicate the selected toner color. Note that the selection states of the various modes described above are stored in the working RAM 42 which is backed up by a battery. In addition to the various display controls described above, the main body CPU 41 controls various operating parts within the copying machine main body 20, as shown in FIG. 'r2'i Simultaneous Copy Mode Next, the simultaneous copy mode will be explained with reference to FIGS. 1, 2, and 20. Cyful copying mode uses at least two developing devices in one copying operation, and controls the operation timing of each developing device in relation to each other, thereby developing a specified area with a specified toner color. mode. Note that in the apparatus of this embodiment, the process is executed for the final document (cover document) under the setting of cover mode 3. First, in FIG. 1, the exposure position where the original image scanning light f forms an image on the photoreceptor drum 21 is U1, and the first development position where the first developing device 22a develops the electrostatic latent image on the photoreceptor drum 21. V1 The second developing position where the second developing device 22b develops the electrostatic latent image on the photoreceptor drum 21 is assumed to be W. Further, it is assumed that the document scanning speed and the peripheral speed of rotation of the photosensitive drum 21 are correlated at a predetermined ratio depending on the copying magnification. In addition, in FIG. 2, the document tray on the document platen glass 26 is painted so that the area R1 from the right end of the document tray to the boundary r1 is black (second developing unit 22b), and the area R2 from the boundary r1 to the boundary r2 is black. Red (first developing device 22a) and black (
It is assumed that the second developing device 22b) is used to copy each image. In this copying apparatus, the boundary is defined by rl, which is the lever 25a,
r2 is designated by lever 25b. Here, the levers 25a and 25b are slidably installed in a groove 25c installed along the scanning direction in front of the document platen glass 26, and a magnet 25am,
25bm is attached (Fig. 2(b)). Above groove 2
A moving body 25 that moves together with the scanning body (not shown) of the scanning optical system is disposed below 5c.
The reed switch 25s mounted on the magnets 25am and 25b when scanning the document in the direction of the broken line arrow X
m and is detected, and based on the detection signal, the timing for switching the operation of the two developing devices is given. That is, as will be described later, when preparation for copying the final original is completed with cover mode 3 selected and the simultaneous copy mode is commanded, two developing devices are selected as shown in FIG. 20(a). (See Figure 16, 5733). Furthermore, when the flag for managing the start of the copy operation is set to "1" and the start of the final copy operation is commanded as shown in FIG. 20(b), the command signal is raised. At the timing of falling F7':, the second
The developing device 22b (black) is activated and a developing operation by the developing device is started. Next, when the movable body 25 reaches a position directly below the lever 25a as the document is scanned, the reed switch 25S is turned on. At the timing when the electrostatic latent image generated at the ON time reaches the first development position V from the exposure position [U] (time tl after the falling edge of the signal at the ON time), the electrostatic latent image shown in FIG. 20 (
f) As shown in (g), the developing operation by the first developing device 22a (red) is started. Furthermore, at the timing when the electrostatic latent image generated at the on-time reaches the second development position W from the exposure position U (1.+1. hours after the falling edge of the signal at the on-time), Figure 20 (d) (e)
As shown in FIG. 2, the operation of the second developing device 22b (black) is stopped. In this way, the area R1 from the right end of the document sheet to the boundary r1 is developed by the second developing device 22b (black), and further, the developing operation by the first developing device 22a (red) for the area R2 after the boundary r1 is started. . Next, when the movable body 25 reaches directly below the lever 25b, the reed switch 25s is turned on again, and the timing at which the electrostatic latent image at the on time reaches the first development position V from the exposure position U (the signal at the on time is 1 hour after the falling edge of ), the operation of the first developing device 22a (red) is stopped. t++tx time after the falling edge of the ON time signal), the second developing device 22b (
The development operation using black) is restarted. In this way, the region R2 between the boundary r1 and the boundary r2 is developed by the first developing device 22a (red), and the developing operation by the second developing device 22b (black) for the region R3 between the boundary r2 and the left end of the document is restarted. As described above, under the cover mode 3 setting, for the cover document, area R1 is copied in black, area R2 in red, and area R3 in black, respectively, in the mode (cycel copy mode). operation is realized. Note that this operation is
It is controlled in the copy operation process (FIG. 18: 5809) which will be described later. In addition, although the simultaneous copy mode has been described above as a mode in which 3 divided areas (areas R1, R2, R3) are developed in two colors (black-red and black), there are also other modes in which 3 divided areas can be developed. Two-color development by replacing the developer (red → black - red)
There are various simultaneous copying modes, such as a mode in which three divided areas are developed in three colors (black-red and blue), and a mode in which two divided areas are developed in two colors (red-black). In addition, in the simultaneous copy mode that divides the document area into two, lever 2
The signal from the reed switch 25s when passing '5b is ignored.

Details will be described later. *Other processing 2 Processing other than the above, which is executed by the CPU 41
This is a step that collectively shows the processing executed in . After executing each of the above processes, the process waits for the internal timer to end (533), and then returns to step 813 and repeats the above processes. The above is an outline of the processing performed by the CPU 41. Next, each subroutine process will be explained. <u) Cover mode key processing: Figures 6 to 10 Cover mode key processing (317) is performed when the cover mode key 55 is pressed when the ADF 10 is attached to the main body 20 (S103; YES). , that is, when the on-edge is detected (S101; YES), the execution is executed and "...-
The cover mode is switched in the order of "Cover Moto 1 Cover Mode Key→Cover Mode 3 - Cover Mode Cancellation - Cover Mode 1". For example, if cover mode 1 is selected and the LED element 55a is lit (Slll; YES), cover mode 2 setting processing (3113, see Figure '17) is executed. Similarly, if cover mode 2 is selected (S121;
YES), cover mode 3 setting processing (S123, see Figure 8) is executed, and if cover mode 3 is selected (5131; YES), cover mode 1, 2.3 cancellation processing (5133, No. 9) is executed. Note that if no cover mode is selected (3131; N

If the cover cassette is set in the upper paper feed port (S417.YES), the lower paper feed port is selected as a general rule (S429). Furthermore, if the upper paper feed port is currently selected as the paper feed port (S421; YES), the lower paper feed port is selected as a general rule (S429). However, if the cover mode 1 is not set, or even if the cover mode 1 is set, the upper paper feed slot is a cover cassette or the lower paper feed slot is not a cover cassette (5423; YES, or
5425; YES or 3427; NOI is the condition. Note that if a cover cassette is set in the lower paper feed port (S427; YES), an automatic paper selection mode (a mode for automatically selecting a paper feed port) is set (3439). If the lower paper feed port is selected as the paper feed port (S431; YES), automatic paper selection mode is set (3439). Also, in a state where neither the manual paper feed port nor the upper paper feed port nor the lower paper feed port is selected as the paper feed port (3431;

This process is executed when the on-edge of the document set signal transmitted to U41 is detected (8503; YES). First, size data of the original set on the original tray 11 (this data is calculated by the CPU 45 based on the state of a group of switches (not shown) that are turned on/off by the original regulating plate (not shown) of the original tray 11, (transmitted to the CPU 41) is stored in register A of the CPU 41 (350
5). Next, the above size data is multiplied by a copy magnification value selected by a magnification key (not shown), etc., and by the multiplied value,
The contents of the register A are updated (5507). In this way, register A stores data on the required copy paper size. Thereafter, the paper feed ports are searched in the order of "upper stage - lower stage", and the paper feed port in which copy paper of the required size is stored is selected. However, the condition is that no cover cassette is set in the paper feed slot. For example, if copy paper of the required size is stored in the upper paper feed cassette 28 (551l; YES)
), cover mode 1 is set (351
3; No), or even if cover mode 1 is set, the size mismatch flag is set to "0" on the condition that the cover power cent is not set in the upper paper feed slot (S515; NO). It is reset (S517) and the upper paper feed port is selected (S519). Also, the LED element 54b indicating the selection state of the upper paper feed port is turned on (5521), and the LED element (any one of 54h to 54n) indicating the size of the copy paper stored in the upper paper feed cassette 28 is turned on. (5

O, or 5607; NO), cancel cover mode 2 and cover mode 3, and turn on those display LEDs 55b and 5.
5c is turned off (5609). Furthermore, the color display corresponding to the color of the data stored in the cover color hood area of the RAM 42 is turned off (3611). This is because with the cancellation of cover mode 2.3, there is no longer a need to display colors for the cover. Also, the cover copying flag is reset to "0" (3613). (vii) Cover mode switching process: Figures 16 and 17 In this process, before copying the final document (cover document), necessary copying operations are prepared in the set cover mode. A document is set on the document table 26 (3701;
YES), and there is no original remaining in the original tray 11 of the ADF 10 (5703・YES), in other words, when the original set on the original platen 26 is the final original, the cover copying flag is set. is reset to "0"(S705; YES), the following processing is performed depending on the type of cover mode. For example, if cover mode 1 is set (37

Select both developing devices as the developing devices to be used (
3733). Further, after the processing in steps 5713, 5723, and 5733, the cover copying flag is set to "1". This is because these processes only need to be executed once. Note that the cover copy flag is set before the final document is set (S701; NO, or 3703; NO) and when the cover mode is not set (5731; NO).

Copying operation processing (5809 - Processing for performing various controls necessary for copying operations 8) Note that under the settings of Cover Moto 3, simultaneous development control that switches the developer at a predetermined timing during a single copying operation is also performed in this step. (executed with) before execution,
Check whether or not there is paper in the paper feed port set for the cover (5803), and if there is no paper, the copy paper empty display LED 54W is turned on (S807). In this case, the copy operation process in step 5809 is not executed. Additionally, if it is determined that there is copy paper in the cover paper feed slot, the copy paper empty display LED 54w is turned off (
S805), the copy operation process of step 5809 is executed. Note that the above check process (3803) is executed as shown in FIG. That is, the paper feed port set for the cover paper is connected to the sensors 28sl and 29s that detect the cover cassette.
After being detected by the signal 1, the presence or absence of paper in the paper feed port is determined. The present copying apparatus is controlled in the manner described above, and in the cover mode setting, predetermined preparations are performed prior to the copying operation of the final original.

【Effect of the invention】

As described above, the present invention is an apparatus that performs simultaneous copying of a cover document under the cover mode (cover mode 1 in the embodiment). According to the present invention, it is possible to easily identify copies of a series of manuscripts consisting of a content manuscript and a cover manuscript, and it is also possible to meet the demand for diversification of cover modes. Further, the cover mode can also be realized by simple key operations.
