Abstract

PURPOSE:To improve the operability and to attain a high speed copying by devising the system such that equipment groups connected in cascade make double side copying when double side copy is commanded by a master equipment. CONSTITUTION:The system is formed by connecting plural digital copying machines in cascade as picture processing units (cascade connection system). Then each is provided with a system address respectively. When double side copy is executed in the cascade connection copy, a double side mode key 256 is depressed. In this case, a master equipment issues a setting command of the double side mode to set all the equipment groups connected in cascade entirely to the double side copy mode. When a copy start key 253 is operated, the equipment group starts the copy operation simultaneously in the double side mode. Thus, the double side copy is sequentially implemented and when all the processing is finished, the succeeding copy processing is awaited. In this case, each equipment set in the double side mode returns to the usual copy mode.

The printer unit 100 of the present embodiment is capable of forming full-color images of four colors by using four color toners of magenta, cyan, yellow, and black, which correspond to magenta, cyan, yellow, and black, respectively. It has four imaging stations that are independently installed. Each station has a photosensitive drum 101 as an image carrier.
a to 101d, and the surface of each photosensitive drum is uniformly charged by the primary high voltage charger and the grid high voltage units 103a to 103d.

After the uniform charging, the laser scanning systems 102a to 102a based on the image information of each color scanned by the laser optical system 107.
By 02d, an image corresponding to each color is exposed on the photosensitive drum to form an electrostatic latent image. The latent image corresponding to each color image information is developed into a toner image by the developing devices 104a to 104d having toners of magenta, cyan, yellow, and black, and the toner image is transferred by the transfer chargers 105a to 105d, which is a document conveying unit. The image is transferred onto the transfer medium conveyed on the belt 108. The residual toner on each photosensitive drum is removed by the cleaning devices 106a to 106d.

<Double Sided Image Forming Sequence> The double sided image forming sequence in the printer section 100 of the present embodiment will be described below by using an example in which the upper cassette is fed. For the transfer medium P loaded in the paper feed cassette 110a, the first paper feed roller solenoid (not shown) is turned on at the same time when the image formation start signal is turned on, and the transfer medium P in the cassette is transferred.
Sheet feeding operation is started. The transfer medium P fed from the cassette is conveyed by the conveyance registration rollers 113 and 114, and a predetermined loop is formed and temporarily stopped while the leading end of the transfer medium P abuts against the first registration roller 115.

On the other hand, when the image formation start signal is turned on, the original document on the platen is read by the CCD 201, and the read image signal is subjected to the above-mentioned image processing and
It is stored in the memory unit 208 in the image processing unit 215. After the image data read in the memory unit 208 is ready for laser scanning, the driving of the first registration roller 115 is started. By this driving, the transfer medium P is adsorbed and conveyed to a predetermined position on the transfer belt 108 for image formation.

Then, the image of each color is transferred onto the transfer medium P by the image forming process such as the laser scanning described above.
At this time, the image information of the original document stored in the memory unit 208 is transferred onto the transfer material medium at each timing when the transfer medium P passes through the magenta, cyan, yellow, and black stations. Is read out to be sent to the printer unit 100, and written on the photosensitive drum of each color by the laser optical system 107 of the printer 100.
The transfer medium P, which has passed through four stations in sequence and has multiple transferred images, is then fixed with a toner image by fixing means 109 for fixing the toner.

When the paper reverse detection sensor 119 provided at 127 is passed, the reverse drive solenoid SL5 (not shown) is turned on,
The forward / reverse rotation roller 126 rotates in the reverse direction. As a result, the transfer medium P
Switches back, and the second transport unit (transport roller 12
0). Deflection plates 121 and 122 for each paper size convey the transfer material P conveyed into the intermediate tray 118 by driving the paper deflection plate solenoids SL7 and SL8 (not shown) according to the size of the transfer material P. Change the route.

When the first transfer material P is conveyed into the intermediate tray, the re-feed roller releasing solenoid (not shown) is turned off once, and the rotating re-feed roller (second
The paper feed low) 112 is lowered onto the transfer medium P. By this, the transferred transfer material P is abutted against a paper stopper plate (not shown) so that the tray paper sensor (not shown) can surely detect the copy paper.

By the series of operations described above, the transfer materials, on which the image formation on the first side is completed, are sequentially stacked in the intermediate tray 111, and are on standby in preparation for the image formation on the second side. In this state, the sheet re-feeding roller 112 is lowered onto the transfer medium stacked in the tray. In this state, when the second surface image formation start signal is issued,
The image forming operation for the second surface is started. That is, the second
The transport unit drive solenoid (not shown) is turned on, the re-feed roller 112 rotates, and one transfer medium P in the tray is re-fed from the top.

When the first transfer material starts to be fed, that is, when the transfer roller 132 starts to convey the transfer material, the re-feed roller 112 moves up. When the feeding of the first transfer material is completed, the rotating second feeding roller is lowered at a predetermined timing to feed the next transfer medium (second sheet). The sheet re-feeding roller 112 repeats this up and down operation. The re-fed transfer material is conveyed by the conveying roller 114, its tip hits the first pair of registration rollers, forms a predetermined loop, and is temporarily stopped. Is fixed / conveyed on the transfer belt 108 which is a conveying means at the timing of
An image on the second side is formed by passing through the first to fourth stations.

After the image is formed, the toner image is fixed by the fixing means 109 for fixing the toner, and the fixing of the second surface image is completed. On the other hand, when the image formation on the second side is started, the first sheet deflection plate solenoid (not shown) described above is turned off, the first sheet deflection plate 124 is returned to the original state, and the image formation on the second side is completed. Then, the transfer material which has been fixed is controlled so as to be guided to the discharge roller. As a result, the transfer material is discharged and stacked on the discharge tray.

After discharging the final transfer material, all the series of operations are completed. <Structure of Duplex System> First, the interface unit 300 of each station will be described.

The image transfer end command is used by the image transfer source station to report the end of image transfer to another station. <Double-sided Copy Performed by Double-sided System> Next, double-sided copy performed by the double-sided system of this embodiment will be described. The following description will be made with reference to the flow chart of FIG.

As shown in step S1 of FIG. 7, the apparatus of this embodiment, which has completed the initial processing, monitors the operation input from the operation unit or the reception from another apparatus. FIG. 8 shows an example of the operation unit of the master device in this state. In FIG. 8, 251 is a numeric keypad, 252 is a reset key,
Settings and operations of the apparatus of this embodiment are reset. Reference numeral 253 is a copy start key. Copy start key 253
Pressing starts the copy operation. Also, 25
Reference numeral 4 is a display unit such as a liquid crystal display. The display unit 254 has touch panel keys in a form corresponding to the display. The key input from the touch panel key is the ten key 251 or the copy start key 253.
It is handled indistinguishably from hard keys such as. The display displayed on the display unit 254 in FIG. 8 is one example. Further, 255 is a double key for performing double link operation,
A double-sided mode key 256 is used for double-sided copying.

In this display state, if there is an operation input from the operation unit or a reception request from another device, step S2
Proceed to. Then, in step S2, it is checked whether or not the duplicate key 255 is pressed to select the duplicate copy. Here, if the multiple copy is not selected, the process proceeds to step S3, and control according to each input and request is performed. When these corresponding processes are completed, the process returns to step S1.

If the multiple key 255 is pressed in step S2, the flow advances to step S5 to display the multiple copy designation screen shown in FIG. 9 on the display unit 254 of the operation unit. That is, the display unit 254 displays a picture (or a symbol representing the same) of a device group (or a device group capable of operating in a multiple connection) connected in a multiple connection, and a message "Copy in a multiple connection." To be done. At this time, all the pictures (or the symbols representing them) of the device groups (or the device groups capable of multiple operation) connected in the multiple connection are in a blinking (or lighting) state.

Then, in step S6, the next instruction input is awaited. The operator either sets the document to be copied on the reader unit 200 and presses the copy start key 253 to start copying, or selects the double-sided mode with the double-sided mode key 256 and then starts copying. I will do that operation. Copy start key 25 immediately
When pressing 3 to start copying, the process proceeds from step S7 to step S8, and the multiple copy process in single-sided copying is executed. After the processing is completed, the process returns to step S1.

On the other hand, when performing double-sided copying in the continuous copying, the double-sided mode key 256 is changed from the state shown in FIG.
Press and enter. In this case, the process proceeds from step S7 to step S10, in which the master device issues a double-sided mode setting command to set all the device groups (or the device groups capable of double-sided operation) connected in the double-sided copy mode to the double-sided copy mode. .
Then, in step S11, the input of the copy start key 253 is awaited.

When the copy start key 253 is pressed, the process proceeds to step S12, and the above-mentioned device groups simultaneously start the copy operation in the double-sided mode. At this time, the display unit 254 of the operation unit changes to a message display of "duplex copying on both sides." As shown in FIG. In this way, double-sided copying is sequentially performed, and when all the processes are completed, the process returns to step S1 to wait for the next copying process.
At this time, each device set to perform double-sided copying returns to the normal copy mode.

As described above, according to the present embodiment, when a double-sided copy operation is instructed by a master device during operation in a double-sided system, all double-sided connected device groups are also double-sided copied. It can be set to operate, improving the operability as a cascade system, speeding up copy speed, and
It is possible to effectively use paper resources by double-sided copying. [Second Embodiment] In the above-described first embodiment, when the master device is set to the double-sided copy mode, all other devices are automatically set to the double-sided copy. However, the present invention is not limited to the above-described example, and a double-sided copy capable device and a double-sided device capable of double-sided copying may coexist. Even in such a case, a second embodiment according to the present invention that enables a copy operation that matches the characteristics of each device will be described below.

Also in the second embodiment, the control is the same as the control shown in FIG. 7 of the first embodiment except for the double-sided copying operation in the multiplex mode. That is, in the second embodiment, as shown in FIG.
The processing of steps S10 to S12 is different from that of the first embodiment. In the second embodiment, when it is determined in step S7 that the double-sided copy is instructed by the input of the double-sided key 256, the master device on which the key operation is performed is
Search (or search in advance) for a device that can perform double-sided copy operation in a device group (or a device group that is capable of multiple connection) connected in cascade, and if there is a device that cannot perform double-sided copy operation, The device is in the display unit 254 from the blinking state to the extinguishing state (or from the lighting state to the extinguishing state)

In the case of No. 1, the double-sided copy operation is performed in the multiplex system including only the devices “1” and “3” that are in the blinking (or lighting) state. At this time, the display unit 254 of the operation unit
Message changes from "You can make double-sided copies with multiple stations" to "You are making double-sided copies with multiple stations."

According to the second embodiment described above, even if there are devices that cannot perform the double-sided copy operation in the multi-link system, these devices can be easily specified, and these devices can be operated by the double-sided copy symmetrical device. It is possible to provide an image processing system that can be controlled so as to be automatically removed, has good operability, and can perform reliable output. [Third Embodiment] In the above-described first embodiment, all the devices connected in cascade connection are automatically selected as the output symmetry, and in the second embodiment, the processable devices are automatically selected. All were selected as output symmetry. But,
The present invention is not limited to the above example, and only an arbitrary device in the device group connected in cascade connection may be symmetrical to the automatic control. A third embodiment according to the present invention will be described below, which is configured so that a device which actually wants to perform the double operation can be selected.

In the third embodiment, when the multiple copy display is performed in step S5 in the control of the first embodiment shown in FIG. 7, the display of FIG. 13 is replaced with the display of FIG.
The system waits for input of which device to select. Then, it becomes possible to select another device that is connected in multiple connections from the device that is the master. Check the display in FIG.
For example, when it is desired to perform the multiple-sequential operation with three devices “1”, “2”, and “3” in one device group (or a device group capable of overlapping), the “unit” of the display unit 254 is displayed. By pressing three device symbol display positions of "1", "2", and "3", respectively, or by pressing the ten key 251.
By inputting "1", "2", and "3", the three devices "1", "2", and "3" are specified to be connected in cascade. And copy start key 2
When 53 is pressed, the display on the display unit 254 shifts to the display shown in FIG. 14, and "1", "2" and "3" are displayed.
Repeated operation is performed with 3 units.

When the display unit 254 is a touch panel, the non-selected devices are made to blink, and the blinking "1" to "4" groups of devices connected in cascade (or capable of continuous operation). When you touch the picture (or the symbol that represents it) of the device group), the picture (or the symbol that represents it) changes from blinking to lighting, and you can select which device is operated in multiple operation. A selection method such as "Yes" may be used.

As described above, according to the third embodiment, it is not necessary to uniformly select all the devices that can be connected to each other in series, but it is possible to arbitrarily specify a device to be actually operated, and to operate the multiple system. The property has improved. The present invention may be applied to a system including a plurality of devices or an apparatus including one device.

Needless to say, the present invention can also be applied to the case where it is achieved by supplying a program to a system or an apparatus.
