FIG. 1 schematically shows an embodiment of the present invention. This embodiment is an embodiment of the invention according to claims 1 to 4 and is an example of a multifunction digital copying machine, and includes a copying machine main body 11, an automatic document feeder 12, a sorting device 13, and a duplex reversing unit 1.
4 The copier body 11 includes a scanner, an image processing unit, a plotter, and the like.
5 and a first mirror 17 which is provided with a reflecting mirror 16 and a first mirror 17 and is driven by a scanner servomotor to move at a constant speed when scanning an original, and a second mirror 18 and a third mirror 19. Is driven by the scanner servo motor during document scanning, and is １ ／ of the first scanner.
And a second carriage that moves at a speed of.

An original (not shown) on the original table 20 is optically scanned by the first carriage and the second carriage, and the original on the original table 20 is illuminated by the light source 15 and the reflecting mirror 16 to form a reflected light image. An image is formed on the one-dimensional solid-state imaging device 23 via the first mirror 17, the second mirror 18, the third mirror 19, the color filter 21, and the lens 22, and photoelectrically converted.

As the light source 15, a fluorescent lamp, a halogen lamp, or the like can be used, but a fluorescent lamp is used because its wavelength is stable and its life is long. In this embodiment, the reflecting mirror 16 is attached to one light source 15, but two or more light sources can be used. In addition, since the one-dimensional solid-state imaging device 23 operates with a sampling clock having a constant frequency, the fluorescent lamp 15 is turned on at a frequency higher than that frequency, so that there is no adverse effect on the image.

The one-dimensional solid-state imaging device 23 uses a CCD, and an image signal from the CCD 23 is supplied to an A / D (not shown).
The data is A / D converted by the converter and output to the image processing board 24 constituting the image processing unit. The image processing board 24 performs various image processing (binarization, multi-valued gradation processing, scaling processing, editing, etc.) on the image signal from the A / D converter, and outputs a digital signal corresponding to a set of light spots. And output it to the plotter.

In this embodiment, a color filter 21 that transmits only light of a required color is disposed in the optical path from the original on the original table 20 to the CCD 23 so that a color image signal can be obtained by the scanner. ing. The color filter 21 is moved in and out of the optical path in accordance with the scanning of the document on the document table 20. In response to this, functions such as multiple transfer and double-sided copy work to create a variety of copies.

In the plotter of the copying machine main body 11, the image signal after image processing from the image processing board 24 is written to the photosensitive drum 25 by raster writing in the form of a set of light spots. In this writing section,
The semiconductor laser is modulated and driven by an image signal after image processing from the image processing substrate 24 by the semiconductor drive circuit, and outputs a laser beam having an intensity corresponding to the image signal. This laser beam is converted into a parallel light beam by a collimating lens. The light beam is changed and shaped into a light beam of a certain shape by the aperture of the aperture member. The shaped laser light is incident on the polygon mirror 30 in a form compressed in the sub-scanning direction by the first cylinder lens.

The polygon mirror 30 has an accurate polygonal shape, and is rotated by a polygon motor 31 in a fixed direction at a fixed speed. The rotation speed of the polygon mirror 30 is determined by the rotation speed of the photosensitive drum 25, the writing density of the writing unit, and the number of surfaces of the polygon mirror 30. The laser light from the first cylinder lens is deflected in the main scanning direction by the polygon mirror 30, and the fθ lens 3
3. The light enters the photosensitive drum 25 via the mirror 35.

The fθ lens 33 converts the scanning light from the polygon mirror 30 at a constant angular velocity so as to scan the photosensitive drum 25 at a constant speed and forms an image on the photosensitive drum 25 so as to have a minimum light spot. Further, the tilt correction of the polygon mirror 30 is also performed. The laser beam that has passed through the fθ lens 33 is reflected by the synchronization detection mirror outside the image area, introduced into the synchronization detection light input section, propagated by the optical fiber, and detected by the synchronization detection sensor.

The signal from the synchronization detecting sensor is used as a synchronization signal for performing cueing in the main scanning direction, and after a predetermined time from this synchronization signal, the image signal after image processing from the image processing board 24 is replaced by one line. And the semiconductor laser is modulated by the image signal. This operation is repeated, and one image is written on the photosensitive drum 25.

A photosensitive layer is formed on the peripheral surface of the photosensitive drum 25. The photosensitive layer is formed of an organic photosensitive member, α-Si, Se-, which is sensitive to a laser beam having a wavelength of 780 nm from a semiconductor laser 26. Although there is Te or the like, an organic photoreceptor is used in this embodiment. Generally, when writing to a photosensitive drum by laser light, there are a negative / positive process of applying light to an image portion on the photosensitive drum and a positive / positive process of applying light to a background portion on the photosensitive drum.
In this embodiment, a negative / positive process is employed.

The charging charger 39 is of a scorotron type having a grid on the photosensitive drum 25 side, and uniformly charges the surface of the photosensitive drum 25 negatively. The photoreceptor drum 25 is driven to rotate by a motor and is uniformly charged by a charging charger 39, and then is charged into the mirror 3 of the writing unit.
The electrostatic latent image is formed by irradiating the laser light from No. 5.
In this case, for example, the background of the photosensitive drum 25 is -75.
0 V to -800 V, and the image portion is about -500 V.

The main developing device 40 and the sub developing device 41 have a voltage of -500V.
A developing bias voltage of -600 V is applied to the developing roller, and the electrostatic latent image on the photosensitive drum 25 is developed with negatively charged toner by either the main developing device 40 or the sub developing device 41 to become a visible image. . The main developing device 40 supplies a developer composed of black toner and carrier to the photosensitive drum 25 by a developing roller, and black toner is supplied from a toner replenishing device 42.

The sub-developing device 41 supplies a developer composed of a color toner and a carrier to the photosensitive drum 25 by a developing roller, and a color toner is supplied from a toner replenishing device 43. The main developing device 40 and the sub developing device 41 are selectively driven to a developing position for developing an electrostatic latent image on the photosensitive drum 25, and are usually retracted from the developing position. Each developing operation of the main developing device 40 and the sub developing device 41 is performed by the color filter 21 in the scanner.
In combination with the selection of the reading color information of the original by the switching, the multiple transfer of the transfer paper transport system, and the double-sided copying function, multifunctional color copying and color editing are realized. When developing three or more colors for the electrostatic latent image on the photosensitive drum 25, a method of arranging three or more developing devices around the photosensitive drum 25, and switching by rotating the three or more developing devices. A revolver method of moving to a developing position may be employed.

Then, the transfer paper is transported by the transport device 55, and the visible image is fixed by the fixing device 56 having the fixing roller and the pressure roller.

The residual toner on the photosensitive drum 25 is removed by the cleaning device 58, and the residual potential is erased by the discharging lamp, so that the photosensitive drum 25 can be reused. The photo sensor 60 is disposed between the main developing device 40 and the transfer charger 52,
The reflection density on the surface of the photosensitive drum 25 is optically detected. The writing unit writes a black or halftone pattern on the photosensitive drum 25 at a predetermined timing to form an electrostatic latent image of the pattern, and the electrostatic latent image of the pattern is formed by the main developing unit 40 or the sub developing unit 41. It is developed to become a visible image of the pattern.

The developing ability of the main developing device 40 or the sub developing device 41 is determined from the ratio of the output signal of the photo sensor 60 for the visualized image of this pattern and the output signal of the photo sensor 60 for the background portion of the photosensitive drum 25. As a result, toner is supplied from the toner replenisher 42 or the toner replenisher 43 to the main developing device 40 or the sub developing device 41, and the developing performance of the main developing device 40 or the sub developing device 41 is controlled to be constant.

However, when the operator sets the interrupt mode by the operation unit during the copying in the normal mode, After the operator replaces the original on the original table 20 with the original to be interrupt-copied, the operator presses a key on the operation unit, and the original on the original table 20 is similarly copied. After the interruption copy is completed, the operator replaces the original on the original platen 20 with the original and presses a key on the operation unit to resume the copy operation in the normal mode.

The automatic document feeder 12 feeds the documents one by one to the document table 20 of the copying machine main body 11, and discharges them after copying. The documents are stacked on a document feeder table 67 and are aligned in the width direction by a side guide 68. The originals on the original feeder board 67 are fed one by one by a feed roller 69, and sent to the original stand 20 of the copying machine main body 11 by the transport belt 70.

The data is compressed in 196 and written to the OD by the ODD 215.

The CPU 82 of the main control unit 171 manages the scanner, plotter, image processing unit 173, and operation units 170 and 175 via the scanner unit 172 and the plotter unit 174. At the same time, the scanner 82, the image processing unit 173, The copy mode is also executed using the plotter and the operation units 170 and 175. The application controller unit 166 performs arbitration for executing functions of each application and transferring image data between the scanner and the plotter and each application via the image memory 195.

In this embodiment, each application has a common image memory 195. However, in order to improve the performance of each application, each application may have its own image memory.

Next, the operation of this system will be described. The main CPU 82 of the main control unit 171 manages the scanner, the plotter, and the operation unit, and executes the copy mode. During the execution of the copy, a “print request” signal is input from the application via the SCI 179. And whether the interleave function (function for simultaneously executing a plurality of print functions) is set, and if the interleave function is set, data from the application flows to the plotter at the next paper feed timing. (Here, the main CPU 82 naturally determines which function has a higher priority in a “print request” from which application and which ratio is set to which ratio.) I do). Then, the main CPU82 via the signal of the "print request" from the application until the next paper feed timing is SCI179 input
Otherwise , continue using the plotter in copy mode.

FIG. 7 shows this state. This is because while making four continuous copies in copy mode with a plotter,
This is a case where a print request for received data has been received from an application (for example, the facsimile unit 168), and the main CPU 82 has set “4” in the paper feed counter.

The main CPU 82 first sends a paper feed signal (print command) in the copy mode to the sequence control CPU 81 of the plotter (sequence control CP).
U81 does not need to know which application prints, only main CPU 82 knows which application prints). At this point, the main CP
U82 sets the sheet feed counter to "3". When the paper feed signal is received, the sequence control CPU 81 starts feeding the transfer paper to the paper feed cassette of the plotter, and the transfer paper
When the paper reaches the roller 50, the paper leading edge detection sensor 51
Is turned on to prepare for writing, a "print ready" signal is returned to the main CPU 82.

At this time, the main CPU determines whether or not a “print request” signal is input from the application (a function set as the interleave mode) via the SCI 179, and determines whether a “print request” Is received, a "print ready" signal is input from the sequence control CPU 81, and then a "print ready" signal is returned to the application. in this case,
Since the main CPU 82 is executing only the copy mode, it transmits a "scanner start" signal to the scanner.

When the "scanner start" signal arrives, the scanner turns on the drive system, starts the original reading operation, and outputs image data. At this time, in the gate array 112 for image data selection, the transfer direction of the image signal is set in the direction from the scanner to the image control circuit 102 by the main CPU 82, and the image signal from the scanner is transmitted through the image control circuit 102. The data is transferred to the writing unit and written on the photosensitive drum 25. When the image data is output from the scanner, the sequence controlling CPU 81 rotates the registration roller 50 of the plotter in accordance with the output, and obtains a copy by placing the image on the photosensitive drum 25 on the transfer paper as described above. This copy is discharged by the sorting device 13 to a tray unique to the copy function.

Since the "print request" signal from the application is not input from the SCI 179 within a certain time after the first transfer paper is fed from the paper feed cassette, the main CPU 82 similarly operates in the copy mode.
The sheet of the transfer paper is fed from the paper feed cassette of the plotter. An image is also formed on the second transfer sheet by the plotter in the same process as that for the first transfer sheet to obtain a second copy, and the main CPU 82 sets the sheet feed counter to “2”. The second copy is also discharged by the sorting device 13 to a tray unique to the copy function.

Within a fixed time after the second transfer sheet is fed, the application 168 sends the main CP via the application controller 166 and the SCI 179.
When a "print request" signal is input to U82, the main CPU 82 increments the paper feed counter to "3" and sets the application (facsimile) mode, and the second transfer paper is fed. Within a certain period of time, a paper feed signal is sent to the sequence control CPU 81 in the application mode. Sequence control C
When the feed signal is received from the main CPU 82, the PU 81 starts feeding the transfer paper from the feed cassette of the plotter.
When the transfer paper reaches the registration roller 50 and the paper leading edge detection sensor 51 is turned on to prepare for writing, a "print ready" signal is returned to the main CPU 82.

In this case, the main CPU 82 determines from which application the signal of the “print request” from the application is the signal from which application (the application having the function set as the interleave mode) to be printed. In the case of (1), after a “print ready” signal is input from the sequence control CPU 81, a “print ready” signal for the application 168 is transmitted to the application controller unit 166 via the SCI 179.

When the CPU 188 of the application controller 166 receives the “print ready” signal, the application specified by the main CPU 82 (in this case, the facsimile unit 168) reads the image data from the image memory 195 where the image data is expanded. Copy unit 16
5, the image data is transmitted to the photosensitive drum 2 via the video interface 199, and the sequence control CPU 81 rotates the registration roller 50 in accordance with the image data.
The image on 5 is placed on a transfer paper to obtain a print. This print is discharged by the sorting device 13 to a tray unique to the application 168. At this time, the transfer direction of the image data is changed from the application to the image control circuit 1 by the main CPU 82.
02, the image memory 195
The image data sent from the printer via the vibeo interfaces 199 and 176 is transferred to the writing unit via the image control circuit 102 and written on the photosensitive drum 25.

For the “print request” signal from the application, the function operating on the CPU 188 of the application controller section 166 (in this case, the function operating by facsimile application software) is stored in the image memory 195.
When the image data is expanded above, the application
First, a "print request" signal is sent to the CPU 188 controlling the entire system (at this time, C
PU 188 is an image memory 1 in which image data is expanded by facsimile application software.
95 at the same time), the CPU 188 detects the "print request" signal and
A "print request" signal is sent to U82 via SCIs 200 and 179. When the CPU 188 of the application control unit 166 receives the “print ready” signal from the main CPU 82,
PU 1188 is an image memory 19 designated by a facsimile application (facsimile unit 168).
The image data is sequentially transmitted to the copy unit 165 via the video interface 199 from the address 5.

Since there is no "print request" signal from the application within a certain period of time after the third transfer paper is fed by the plotter, the main CPU 82 similarly operates the plotter in the paper feed cassette of the plotter in the copy mode. The fourth transfer sheet is fed, and the sheet feed counter is set to “1”.
An image is also formed on the fourth transfer sheet in the copy mode by the same process as that for the first transfer sheet to obtain a copy, and this copy is discharged to the tray unique to the copy function by the sorting device 13. .

Since there is no “print request” from the application within a certain time after the fourth transfer sheet is fed by the plotter, the main CPU 82 similarly sends the fifth transfer sheet to the plotter in the copy mode. , And the fifth transfer sheet is caused to form an image by the same process as that of the first transfer sheet and to make a copy. At this time, the main CPU 82 sets the sheet feeding counter to “0” and
The work as the mode ends. The fifth transfer paper is discharged by the sorting device 13 to a tray unique to the copy function.

The main CPU 82 inputs a “print request” signal from the application (the facsimile unit 168) via the SCI 179 within a predetermined time after the fifth transfer sheet is fed by the plotter. CPU 81 for sequence control of paper feed signal in application (facsimile) mode with paper counter set to “1”
Similarly, the plotter feeds the sixth transfer sheet, and a print is obtained in the same process as the third transfer sheet. At this point, the main CPU 82 sets the paper feed counter to “0”. The sixth transfer paper is discharged to a tray unique to the application 168 by the sorting device 13.

The main CPU 82 does not input a “print request” signal from the application via the SCI 179 within a predetermined time after the sixth transfer sheet is fed by the plotter, and the sheet feed counter is set to “0”. Because
The plotter does not operate without sending a "print" signal to the sequence control CPU 81. However, after that, since a "print request" signal is generated from the application (the facsimile unit 168), the main CPU 82 sends a paper feed signal to the sequence control CPU 81 in the application (facsimile) mode at that time. To cause the plotter to feed the seventh transfer sheet. An image is also formed on the seventh transfer sheet by the same process as that for the third transfer sheet, and is discharged to a tray unique to the application 168 by the sorting device 13.

In this manner, the image data read from the scanner and the application are stored in the image memory 19.
5 realizes an interleaving function with the image data written on the image data.

Next, interleaving of image data written on the image memory 195 by a plurality of applications will be described. FIG. 8 shows this interleaving. This is a case where a print request is received from the facsimile unit 168 during continuous printing of three sheets in the file mode.

The CPU 188 operates the ODD 21 by using the file application software in the ROM 214.
5, the image data reproduced from the OD is expanded by the CEP 196 and expanded in the image memory 195, and then a signal of “print request” is received from the file unit 167. Then, the CPU 188 sends a “print request” signal as a file mode to the main CPU 82 via the SCIs 200 and 179 based on the signal.

The main CPU 82 sets the paper feed counter to "1" in response to the "print request" signal, and sends a paper feed signal to the sequence control CPU 81 of the plotter in the file mode (sequence control CPU 81).
Does not need to know which application prints, only the main CPU 82 knows which application prints). At this time, the sheet feeding counter is set to “0”.

When the paper feed signal is received, the sequence control CPU 81 starts feeding the transfer paper to the paper feed cassette of the plotter. When the transfer paper reaches the registration roller 50, the paper leading edge detection sensor 51 is turned on. When ready to write, print ready signal is sent to main CPU
Return to 82. The main CPU 82 determines from which application the signal of the “print request” from the application is a signal. If the signal is an application to be printed (application of a function set as an interleave mode), the sequence control After a “print ready” signal is input from the CPU 81, the application controller 166
To send a "print ready" signal.

Application controller section 166
When the "print ready" signal is received, the application (in this case, the file unit 167) designated by the main CPU 82 transmits the image data from the image memory 195 where the image data is expanded to the video interface 199. Copy unit 165 via
The sequence control CPU 81 rotates the registration roller 50 in accordance with this, and places the image on the photosensitive drum 25 on the transfer paper.

At this time, in the gate array 112 for image data selection, the image data transfer direction is set by the main CPU 82 in the direction from the application to the plotter, and the image data from the image memory 195 passes through the image control circuit 102. The first print is obtained by being transferred to the writing unit and written on the photosensitive drum 25.
This print is discharged by the sorting device 13 to a tray unique to the file function.

With respect to the “print request” signal from the application, the image data from the ODD 215 is stored in the image memory 1 by the function operating on the application controller unit 166 (in this case, the function by the file application software).
At the time when the image data has been developed on the image memory 95 (if it is not necessary to develop the image data on the image memory 195, it is sufficient if a format capable of outputting image data for immediate printing by a "print ready" signal is created). application·
First, a "print request" signal is input from the file application 167 to the CPU 188 controlling the entire system (at this time, the file

The CPU 188 sequentially sends the image data to the copy unit 165 via the video interface 199 from the address of the image memory 195 designated by the file application software.

The main CPU 82 sends a "print request" signal from the file application (file section 167) within a certain period of time after the first transfer paper is fed from the paper feed cassette by the plotter to the SCI 200, 17.
9, the sheet feed counter is increased by one to “1”, and the sequence control CPU 81 feeds the second transfer sheet in the file mode. At this point, the main CPU 82 sets the paper feed counter to “0”. 2
An image is formed on the first transfer sheet by the same process as that for the first transfer sheet, and the sheet is discharged by the sorting device 13 to a tray unique to the file function.

The CPU 82 sends a “print request” signal from the file application 167 to the SC within a predetermined time after the second transfer sheet is fed by the plotter.
Input via I200 and 179, the sheet feed counter is set to “1”. At the same time, the CPU 82 sends a "print request" signal from the facsimile application (the facsimile unit 168) to the SCI 20 from the CPU 188.
0, 179 (the facsimile application 168 transmits the data from the public line to the CEP).
After decompression by 196 and development in the image memory 195, a "print request" signal is sent to the CPU 188), and the paper feed counter is increased by one to "2".

Thereafter, the main CPU 82 sends a paper feed signal in the facsimile mode to the sequence control CPU 81 within a predetermined time after the second transfer paper is fed by the plotter, and supplies the third transfer paper. Let the paper do. At this point, the main CPU 82 sets the paper feed counter to “1”. When the paper feed signal is received, the sequence control CPU starts feeding the transfer paper from the paper feed cassette of the plotter, and writes when the paper leading end detection sensor 51 is turned on when the transfer paper reaches the registration roller 50. When ready, a "print ready" signal is sent to the main CPU 82
To return.

The main CPU 82 determines from which application a “print request” signal is issued, and in the case of an application to be printed (application having a function set as an interleave mode), outputs a “print ready” signal. application·
It is transmitted to the control unit 166. In this case, the “print request” signal from the file unit 167 was transmitted before the “print request” signal from the facsimile unit 168, but later the “print request”
The facsimile unit 168 to which the signal was transmitted is the file unit 16 to which the "print request" signal was transmitted first.
Since the priority is set higher than 7, the main CP
U82 first determines the application
In the application (facsimile) mode, a “print ready” signal of the facsimile unit 168 is sent to the control unit 166 first.

Application control section 166
When the "print ready" signal is received, the application designated by the main CPU 82 (in this case, the facsimile unit 168) transfers the image data from the image memory 195 where the image data is expanded to the video interface 199. Copy unit 1
65, and the main CPU 82 causes the sequence control CPU to rotate the registration roller 50 so that the image is placed on the transfer paper to obtain a print. This print is discharged by the sorting device 13 to a tray unique to the facsimile function.

The main CPU 82 sets the sheet feeding counter to "1".
There is no "print request" signal within a certain period of time after the second transfer paper is fed, but the file unit 167 is suspended when the third transfer paper is fed. Since there is a “print request” signal, the sequence control C is performed within a certain time after the third transfer sheet is fed.
The PU is caused to feed the fourth transfer sheet in the file mode. An image is formed on the fourth transfer sheet by the same process as that of the first transfer sheet to obtain a print, and this print is discharged to the tray unique to the file function by the sorting device 13. In this way, an interleaving function of the image data written on the image memory 195 by the plurality of applications is realized.

Next, setting of interleave function
This will be described with reference to FIG. This is set by the user or the service person using the operation unit. When the user or serviceman enters a setting mode such as SP (serviceman program) mode, the main CPU 82 checks an input signal from the operation unit and returns if no application is provided. At this time, the main C
The PU 82 causes the guidance display unit 143 to display "No application" for a certain period of time and exits the mode.

When an application is provided, the main CPU 82 displays a message “Set interleave? 0: No 1: Yes” in the guidance display section 143.
_ ”Is displayed.

The main CPU 82 checks the signal from the operation unit, exits the mode when “0” is selected by the operation unit, and displays the guidance display unit 143 when “1” is selected. Interleave MAX value is XX
Application. Set the application to interleave. 1: Copy 2: Facsimile 3: Printer 4: File _ "is displayed and MAX can be interleaved
The value xx (the number of trays of the sorting device) and the application (application) with an interleave are also displayed on the guidance display unit 143, and the number of the application to be interleaved and the number of the trays of the sorting device 13 for storing the print are displayed. The interleave is set by allowing the user or serviceman to make settings on the operation unit and storing them by a signal from the operation unit.

Here, if there is no sorting device 13 and one tray is set in the copying machine main body 11 instead of the sorting device 13, the main CPU 82 sets the sorting device 13.
In response to a signal from a sensor for identifying the tray and the tray, the guidance display unit 143 displays "Interleave cannot be performed because there is no sorting device" and exits the mode.

The main CPU 82 sequentially sets the interleave setting for each application as described above. When the number of trays that can be used by the sorting device 13 reaches the MAX value, or when the interleave setting is completed, ,
In the guidance display section 143, "Please set the priority of interleaving. 1: Copy 2: Facsimile
3: Printer 4: File _, _, _, _ ”is displayed, and the interleave setting of each application is set to the same number as the number of trays that can be used by the sorting device 13 or to an order smaller and higher in priority. I do.

When the interleave setting is completed, the main CPU 82 causes the guidance display section 143 to display “Please set the interleave ratio. Copy: facsimile: printer: file = _: _: _: _”. Copy the interleave ratio (copier body 1
1) The facsimile, printer, and file (file processing function) are set by the user or serviceman on the operation unit and stored by a signal from the operation unit to copy the interleave ratio, and set the facsimile, printer, and file. I do. This ratio is a ratio at which, when a "print request" signal is simultaneously generated in the copying machine body 11, facsimile, printer, and file, the printing is executed.

For example, the priority order is set to “copy facsimile printer file” and the ratio is set to “copy: facsimile: printer: file = 3: 1:
When “2: 1” is set, the main CPU 82 copies and prints according to the set interleaving application, its priority (printing order) and ratio.
Mode and each application mode (facsimile,
Mode, printer mode, and file mode) to sequentially print data from each application as described above. That is, the main CPU 82 first causes three copies to be printed in the copy mode, then causes one print in the facsimile mode, then causes two prints in the printer mode, and then causes the file to be printed.・
The print operation is executed at a designated ratio such that one print is performed in the mode and then three prints are performed again in the copy mode. In this example, printing in each mode is executed in order of three sheets, one sheet, two sheets, and one sheet, but one copy, one facsimile, one copy,
One printer, one file, one copy, printer 1
Even if the print is divided into sheets, the ratio may be the same as the set value. As described above, the print mode is set, and the main CPU 82 executes the print mode according to the setting, that is, prints the image data expanded in the image memory 195 by a plurality of applications in which interleaving is set. According to the priority and the ratio by the print request from each application, the print request is simultaneously and continuously performed as described above.

Next, the print start check of the main CPU 82 will be described with reference to FIG . This is a routine to check when the interleave mode is set. First, the main CPU 82
Check if it is in interrupt mode. In the case of interrupt mode, it is used when the user wants to perform an urgent process,
Performing the interleave mode is a major obstacle for the user. Therefore, in the case of the interrupt mode, the main CPU 82 returns without performing the interleaving process, and executes only the process in the interrupt mode function. When the main CPU 82 is not in the interrupt mode, the main CPU 82 checks whether or not the paper feed counter is "0". When the paper feed counter is "0", the main CPU 82 returns as there is no "print request" signal.

The main CPU 82 sets the sheet feeding counter to "0".
If not, it is assumed that there is a “print request” signal, and whether there is transfer paper that has already been fed in the plotter (transfer paper that has already been fed in the plotter and has not yet been ejected from the plotter). Is determined based on a signal from a sensor or the like, and if there is already-transferred paper in the plotter, it is determined whether a predetermined time has elapsed since the previous paper was fed. . This fixed time is
This is a predetermined time for maximizing the plotter's print speed.
Alternatively, it differs depending on the image forming process of the plotter, such as thermal writing, and the transfer paper transfer method. When the fixed time has elapsed, the main CPU 82 executes the sheet feeding of the plotter as described above and decreases the sheet feeding counter by one.

Next, the image data check of the main CPU 82 will be described with reference to FIG . This is a routine in which the main CPU 82 returns a “print ready” signal to the application control unit 166 when the paper leading edge detection sensor 51 is turned on when the transfer paper reaches the registration roller 50 and the writing is ready. It is. First, the main CPU 82 checks whether or not the transfer sheet has reached the registration roller 50 based on a signal from the sheet leading edge detection sensor 51. The main CPU 82 uses a transfer paper
If the roller 50 has not been reached, the process returns without performing the process.

When the transfer paper reaches the registration roller 50, the main CPU 82 checks in which mode printing is to be performed. This check is for checking which application is to be printed based on the type of application for which the interleave mode is set, the print priority order, and the print ratio. The order of printing is as described above. When copying is performed in the copy mode, the main CPU 82 sets the image data transfer direction of the gate array 112 for selecting image data to the direction from the scanner to the plotter, and transmits a "scanner start" signal to the scanner.

When the mode is not the copy mode, the main CPU 82 checks whether or not the printing is in the facsimile mode. In the case of printing in the facsimile mode, the main CPU 82 sets the image data transfer direction of the gate array 112 for selecting image data to the direction from the application to the plotter, and
A “print ready (facsimile)” signal is transmitted to the control unit 166. If the printing is not in the facsimile mode, the main CPU 82 checks whether or not the printing is in the printer mode.

Then, in the case of printing in the printer mode, the main CPU 82 sets the image data transfer direction of the gate array 112 for selecting image data to the direction from the application to the plotter, and sends “print” to the application control section 166.・ Ready (printer) ”signal. The main CPU 82 sequentially checks and processes each similar application.

The main CPU 82 prints in the background when the operator is actually working in front of the machine, based on a signal from an operator detecting device for detecting the operator in front of the present embodiment, an operation unit, or the like. Is performed, the operation unit is controlled so that the display of the operation unit remains in the display and mode used by the operator. Whether or not the operator is operating this embodiment can be easily determined by the main CPU 82 based on the time from the last key input from the operation unit to the present, the signal from the operator detection device and the like.

The main CPU 82 also operates when the operator performs printing in the background (printing with a function not used by the operator) when the operator is not actually working before this embodiment. When the display of the section is other than the application for printing in the background, the display of the operation section is not switched. This is because a user who came to use this embodiment may determine that the present embodiment cannot be used if the display of the operation unit of this embodiment is displayed as printing in the background. Is high. In this embodiment, interruption copying in each mode can be performed in the same manner as described above during copying in each mode.

As is apparent from the above description, in this embodiment, in a system in which a plurality of applications exist in one machine, a plurality of copy process functions (print functions) are simultaneously executed. Not only is it possible to always provide the highest performance (print speed ) that the user originally has, but also the operator does not need to consider applications other than the application he is using, and can always use the machine. Further, since applications other than those used by the operator can be executed at the same time, the data input to the multifunction copier can be provided to the user in a timely manner.

Further, even when the interrupt mode is used,
Printing of the application specified by the interrupt can be executed with priority. Since the number of applications that can be interleaved is limited by the number of trays of the sorting apparatus, transfer papers printed simultaneously for each application are not mixed, and confusion of the operator can be prevented. The user can select an application that can execute interleaving, its priority, and the ratio, so that an optimal environment can be set for each user. Further, since the display of the operation unit remains the display and the mode used by the operator, the operator does not need to consider an application other than the application used by the operator, and can perform the operation smoothly.
