The first mirror 7 performs a reciprocating scanning motion together with the exposure lamp 3 to expose the document to slit light. The second mirror 8 and the third mirror 9 are the first mirror 7
The lens 6 moves in synchronization with the movement of the lens 6 so that the optical path length between the document and the lens 6 becomes constant. In the example shown in the figure, when the first mirror 7 moves at a speed τ, the second mirror 8 and the third mirror 9 move at a speed -
The second mirror 7 moves in the same direction as the first mirror 7.

The first photoreceptor 4 is made of Se, 5eTe, Se2As3
etc. is formed. Along the moving direction of the first photoreceptor 4 (in the case of a photoreceptor drum as shown in the figure, around the drum), a large number of charging corona chargers 111 are sequentially mounted.
Df, an eraser that is arranged in a straight line and selectively eliminates static electricity in part or all in the transverse direction with respect to the traveling direction of the photoreceptor; a lamp 12; A developing device 13 for developing, a transfer charge "'w-1" provided at a transfer position for transferring the developed image on the photoreceptor to recording paper.
4. Clean the surface of the photoreceptor after transfer. A cleaning device 15 and a charge eliminating corona charger 8-16 for eliminating residual charges on the surface of the photoreceptor are arranged in this order. Accordingly, the first photoreceptor 4
is charged (for example, 0) and exposed to light by the optical system to form a latent image, and the designated area is neutralized and then transferred to the developing unit 12.
is developed to form a visible image, which is transferred to recording paper.

Eleven sheets of recording paper are sent out from the recording paper storage section 17 by the paper feed roller 18 and are fed to the conveyor belt 20 by the registration rollers 19 at the appropriate timing. Conveyor belt 20
is made of a material such as Mylar' (polyester film), and is wrapped around...21,22,23. The conveyor belt 20 is recharged by a pre-charge corona charger 24, fed by a rear paper feed roller 18, comes into contact with the recording paper, and electrostatically attracts and conveys the recording paper.

While moving, the conveyor drum 20 first comes into contact with the first photoreceptor 4, and then the relative positions of the second sensor 4 and the second photoreceptor 25 are controlled.

The same speed as the circumferential speed of! are driven synchronously.

The second photoreceptor 25 is made of a material having different charging characteristics from the first photoreceptor 4, such as OPO.

Along the moving direction of the second photoreceptor 25 (around the photoreceptor drum as shown in the figure), the second charging corona charger 26, the second optical system 27, the Rin 2 developer 28, and the second transfer charger are installed in order. A 29J2 cleaning device 3° and a second charge eliminating corona charger 31 are arranged.

The second optical system 27 is a half mirror 52 provided in the optical path between the third mirror 9 of the first optical system 5 and the lens 6.
and a lens 53 that forms an image of the reflected light from the half mirror 52, and a COD

It is composed of a convergent light transmitter array 33 that focuses the light image of the LED array 32 on the surface of the second photoreceptor 25. The buffer memory can also be configured to input and store the stored data as serial data for f:l slit lines in an image memory, which is a RAM, and output it as necessary.

The buffer memory can store not only information from the image sensor regarding the original on the original placing plate but also information from other information output devices and output it to the LE'I) array. For example, as shown in FIG. 2, the LED array 32 and the light-converging optical transmitter array (hereinafter referred to as cell 7 lens) 33 of the second optical system 27 form an image on one imaging line of the second photoreceptor 25. Two SELFOC lenses may be arranged in a 7-shape, and the LED array 32 may be arranged opposite the incident end of each SELFOC lens 33. The LED array 32 includes a plurality of chips 32', each chip having, for example, 128 L E D
elements can be included. 2 rows of LED array -3
In 2, the chips 32/ are arranged at positions shifted from each other in a staggered manner, and the missing portion of each chip 32'tm*Ia+鵞i稟子pu is compensated for by the chip 32' of the adjacent LED array 32. □Aww. A'□'・□-; Digital information is imaged on the photoreceptor 25 which is charged (for example, (→charged)) by the LED array 32 and the convergent light transmitter array 33 in accordance with the input electric signal.

A negative latent image is formed on the second photoreceptor 25 by the second optical system 27, and the latent image is positively developed by the second developing device 28. The positive development is transferred to the recording paper under the action of the second transfer charger 29. After the transfer, the second photoreceptor 25 is cleaned and neutralized, and the process from charging is repeated again.

The recording paper that is electrostatically attracted and transported by the transport belt 20 comes into contact with the first photoreceptor 4 at the transfer position, and is transferred to the developing device 13.
A potential having a polarity different from that of the developer, for example 0)t, is applied by the transfer charger 14, and the image on the first photoreceptor is transferred onto the recording paper. The recording paper that has completed the transfer on the first photoreceptor 4 is adsorbed and conveyed as it is by a conveyor belt 20, and comes into contact with the second photoreceptor 25 at the transfer position. 4. To the second transfer charger at the transfer position. A potential (for example, 0) is applied to the second photosensitive drum, and this positive image is transferred to the recording paper. The recording paper after transfer is attracted and conveyed by the conveying belt 20, and is neutralized by the static eliminating charger 34 so that it can be easily separated from the conveying belt 20, and then transferred to the fixing device 35.
For example, the paper is sent to the fixing roller and fixed, and then
6 and discharged onto a tray 37.

The conveyor belt 20 from which the recording paper has been separated is cleaned by the cleaning blade 38, and charged again by the precharging corona charger 24 to carry out the conveyance of the recording paper.

As described above, the composite recording device has two types of operations: a first image forming device that forms an original image on the first photoreceptor 4, and a second image forming device that forms an image on the second photoreceptor 25 in accordance with electrical signals. It has an imaging device.

Table 1 shows an example of the conditions of each image forming apparatus in the embodiment shown in FIG.

The example shown in FIG. 1 can also be implemented under the conditions shown in Tables 2 and 3.

Table 2 Table 3 The first developing device and the second developing device corresponding to the conditions shown in Tables 2 and 3 are basically the same as the device shown in Figure 1, and are equipped with a corona charger and a transfer device. Six numbers are sufficient to select the polarity of the charger and the polarity of the developer, but in the case of the example shown in Table 2, as shown in FIG. In the case of the example shown in Table 3, where the charger 39 is provided at the point 5, the record is transported by the conveyor belt 20 between the first photoreceptor 4 and the second photoreceptor 25, as shown in FIG. The difference from the example shown in FIG. 1 is that a polarity conversion charger 40i is provided to face the paper. The same or corresponding parts as in FIG. 1 are denoted by the same reference numerals and detailed descriptions are omitted.

This is briefly shown in FIGS. 1, 3, and 4, and in FIG.

L2: Recording paper movement distance between the first and second photoconductors As the recording paper is driven in synchronization with the first photoconductor 4 and the second photoconductor 25 in this way, the recording paper moves □( Digital information on the first photoreceptor and the second photoreceptor can be combined and recorded by an external device.

Although an example is shown in which an LED is used in the second optical system of the second image forming device, a method using a laser or an OFT may also be used.

In the above description, the image formed by the first image forming device is first transferred to the recording paper, and the image formed by the second image forming device is transferred later, but the first image forming device and the second image forming device can also be interchanged.

In order to select a location where information from the second image forming device is to be combined with respect to a formatted document formed by the first image forming device, the document conveying device 42 is placed above the original placing plate of the compound recording device as shown in FIGS. 1 and 7. It is installed as shown in the figure and FIG.

A cover 43 made of a transparent member pivotally mounted on the document conveying device 42 is opened and the document is set face up, that is, with the side to be copied facing upward in the figure.

A lattice pattern 44 is drawn on the cover 43 as shown in FIG. 9, and numbers 45 each indicate an address in the X direction (direction corresponding to the document scanning direction during copying) and Y direction (direction perpendicular to the X direction). is displayed. The document conveyance device 42 is provided with an X-direction indicator 47 and a Y-direction indicator 48 in which LEDs are arranged corresponding to each address in the X direction and Y direction of the cover 43o' lattice pattern 44.

The original set under the cover 43 is observed through the cover 43, and the area of the original to be copied is read by the X and Y addresses. For example, if you want to copy the shaded area in FIG. 9, the X direction is 8 to 1-2, and the Y direction is 3 to 8.・

In contrast to specifying the range that you want to copy as described above (for example, the shaded range in α in Figure 12), when you want to combine other information, you can erase part of the document ( Instruct the range to be erased and store it in the device.In this case, turn on the erase key 49α on the operation panel 49,
Below, use coordinate designation key 49C, X key 49e, XY, in exactly the same way as specifying the range you want to erase and copy.
Instructions are input using the key 499, the numeric keypad 51, and the coordinate memory key 49k if necessary. FIGS. 12A and 12S illustrate cases in which the same range is desired to be copied and erased, and the shaded area is the copy area.

Once the copying range or erasing range has been designated, the copying process begins.

When the copy buttons 5o and 5d are turned ON, the document transport row 255 of the document transport device 42 rotates, and a leading end stopper (not shown) that functions to position the leading edge of the original is moved by the action of a solenoid or the like, and the leading edge stopper of the original is moved. Release the effect. The document is sent to the turn roller 56 in the lattice pattern 2mY direction by the curling action of the document conveying roller 55. A belt 57 is wrapped around a part of the turn roller 56, and the document is then sandwiched between the roller 56 and the belt 57 and sent onto the document placement plate 2 of the composite recording device 1. The original sent onto the original placing plate 2 is placed on two rollers 5.
The document is moved to a predetermined position on the document placement plate 2 by the document conveyance belt 58'', which is wrapped around the document transfer belt 58 and moved along the document placement plate 2. At this time, the roller 5 wrapped around the document conveyance belt 580
Reference numeral 9 is driven by a stepping motor, and when the leading edge of the document passes a predetermined position on the document placement plate 2 is detected by the sensor 60, the motor is stopped after counting a predetermined number of pulses. The document is designed to stop at the reference position of the document placement plate. It is convenient to set the amount of movement of the original by the 1 pulse to the size of the pixel unit that will be applied later, that is, the length of the 1 coordinate in the X direction.

When the document stops at the reference position, the copying process by the first image forming device of the composite recording apparatus 1 is activated. child, that is, the first optical system 5
A latent image of the entire image of the original is formed on the first photoreceptor 4,
Next, the erase lamp 12 removes the static charge on the first photoreceptor 4 from an area that does not require copying. .

The erase lamp (optical static eliminator) 12 has a large number of LEDs 612 as shown in FIG. il- juxtaposed in a direction perpendicular to the moving direction of the first photoreceptor 4 (in the case of a photoreceptor drum, parallel to the drum axis), a partition plate 62 is provided between adjacent LEDs 61, and the first It is arranged adjacent to the photoreceptor 4 so that the light from the LED 6'l does not irradiate areas other than predetermined sections.

Each partition plate 62 functions to limit the irradiation range of light from the LED 61. In other words, the first
The size of the opening toward the photoreceptor 4 is determined according to the lattice I of the Carney 43 shown in FIG. The virtual minimum pixel area of 6 houses (13th
), and the number of sections, ie, the number of LEDs 61, corresponds to the number of coordinates of the Y-direction indicator 48 of the grid pattern 44 (12 in the example shown). Each LED 61 of the erase lamp 12 is connected to the erase control device 63 and corresponds to a non-copying range (erasing range) of the first photoreceptor 4 determined by a designated copying range or a designated erasing range according to a command from the erase controller 63. The LED 61 corresponding to the portion is lit to eliminate static electricity in the non-copying area of the first photoreceptor 4. The first photoreceptor, which has had a predetermined range of static electricity removed, is developed by the developing device 13, but since the developer does not adhere to the static-free area, no image is formed when it is transferred to recording paper, resulting in a white area. . Therefore, a copy of a predetermined range or a copy with the predetermined range deleted can be obtained.

Regarding the image erasing range, when the charge on the photoconductor is removed by lighting the erase lamp 12, select the LED 61 and turn it on as described above for the Y coordinate direction.
However, the X coordinate direction (scanning direction) is controlled as follows. In other words, as shown in FIG. 14, the erase lamp 12 is shifted by a certain distance from the exposure position of the first photoreceptor 4 by the first optical system 5, and as shown in the figure, the erase lamp 12 is shifted by a distance in the circumferential direction of the photoreceptor drum. Therefore, the erase lamps 12'r are controlled to turn on sequentially from the X coordinate l with a delay of a time difference Δt,=LE/v from the exposure of the first photoreceptor 4 by the first optical system 5. At this time, a change in the X coordinate portion of the first photoreceptor 4 is detected by an encoder 64 (FIG. 13) that is interlocked with the first photoreceptor 4. The encoder 64 has a time interval Δt o'=
The encoder 64 and the erase control device crystal are electrically connected so as to generate a pulse at Δt/1) and send the pulse to the erase control device 63.

In the erase control device 63, in the first optical system 5 and the exposure run, the leading edge of the original 41 (X coordinate i' of the grid pattern is expressed as the X/coordinate in the original) by 1.3,
After the micro (not shown) that detects the start of exposure at the Xl-0 position) is turned on, the number of pulses from the encoder 64 is counted, and the coordinate The erase lamp 12
An instruction is given to turn on the LED 61, and only the LED 61 facing the Y coordinate corresponding to the erasing range at that time is turned on.

Of course, at the time of the first exposure of the X coordinate of the document and the erase lamp 12
Between the turn-on command at the X coordinate of
control the timing of commands for The length of the photoreceptor 4 in pixel units is △ due to the l pulse from the encoder 64.
It is convenient to configure it so that it moves by t (the length of the l coordinate in the X direction).

In the case of the example shown in Fig. 12a, all L E D61 gold flashing lights are controlled when detecting the X coordinates 11, 2nd, 5th to 7th, 13th and onwards, and when detecting the 3rd to 4th X coordinates, 1st to 4th and 12th L E D61i lighting control, and when detecting X coordinates 8th to 12th, 1st to 2nd and 9th to 12th L

Control the lighting of D61, and control the lighting of the 3rd to 8th L+E D G1w when detecting the 8th to 12th X coordinates, and keep all L E D61 clear for other X coordinates. .

In the copying mode described above, the second image forming device is kept inactive.

(2) When you want to move the selected copy range of the original to a different position on the recording paper that corresponds to the copy range of the original and copy it.

After specifying the copy range or erasure range in ml, turn on the coordinate conversion key 49d in Fig. 1θ, and press the X key 49e1 and the Y key 4.

An example of copying by moving to the range of coordinates (2-6, 5-10) indicated by diagonal lines 5 is displayed.

After inputting instructions for the designated copy range and the designated range to be moved, input instructions for copying conditions similar to the copy mode described in (2) above on the main operation panel 5.
0 and press the copy button 50d.

When the copy button 50d is turned on, the original is set on the original placing plate 2 by the original conveying device 42 in the same manner as described above. At this time, if the amount of document conveyance by one step pulse of the step motor M in the document conveyance device 42 is set to the length Δt in units of pixels, the 7-point sensor on the document placement plate 2 shown in FIG. 60, the distance from the document leading edge detection predetermined position to the document reference position. η=L

Then, by carrying out the normal copying steps such as charging and exposure in the same manner as in the case of embodiment I above, the desired copying position conversion in the Y direction is carried out.

The copying position in the X direction is changed by changing the timing between the start of exposure by the exposure lamp 3 and the first optical system 5 and the start of conveyance of the recording paper by the registration rollers 19.

The difference between the copy specified coordinate X and the converted coordinate X' of the corresponding part after conversion, that is, the movement amount X - X −X'

)””. -, the timing to start transporting the i-recording paper is advanced by 6 pulses compared to the timing during the start of transporting the sz recording paper. As a result, the copy range of the original document can be copied onto a predetermined portion of the recording paper.

As for the copying process after the start of exposure, a generally known copying process is used as in the case of the above-mentioned condition (2).

As mentioned above, if the coordinates X>coordinates
If you want to start feeding the recording paper only with the X-X'l pulse.

Specify the copy range for the first original as described above, set copy conditions as described above using the main operation panel 50, and press the image memory key 50 in FIG. 1'i.
Press t.

As a result, the original is set at the reference position in the same manner as in the case of the above-mentioned mode (2), and then an image is formed by the second image forming device. That is, the exposure lamp 3 and the mirror 7 of the first optical system 5.
The document is scanned by the movement of 8.9, and the light from the exposure scan of the document is imaged by the second optical system 27 on the light receiving part of the image sensor 54 as reflected light from the nof mirror 52, and the image is Stored in buffer memory using electrical signals. In this case, the configuration is such that only the image information of the copying range designated by the signal from the control device is stored in the buffer memory.

Next, the second original is set on the original transport device 42, and the erasure range of the original, that is, the range in which the information of the first original is to be compositely copied, is specified and input using the method described above.

Thereafter, necessary copying conditions are set using the main operation/channel 50, and the memory playback key 50Ci'ON L and copy button sod are pressed.

The second document is set at the reference position in the same way as in the case of the above-mentioned aspect
For example, with the specified range erased on the photoreceptor 4,
In the state shown in lJb, a latent image is formed on the original image and developed. At this time, the second image forming device is operated in synchronization with the first image forming device, and the information stored in the buffer memory is outputted to the exposure LED 32 at a predetermined timing, and the image in the specified range is displayed on the second photoreceptor 25. is exposed to form a latent image and developed. Image formation on the second photoreceptor can be performed by negative exposure and development into a positive image as described above, but if necessary, the second image forming device can also perform gauge exposure, positive development, etc. in the same way as the first image forming device. It is also possible to do so.

First, an image with a portion of the second document erased is transferred from the first photoconductor 4 to the recording paper conveyed by the conveyor belt 20, and then a predetermined area of the first document is transferred by the second photoconductor 25. The image is transferred so as to be combined with the area where the image has been erased by the second photoreceptor. Such a combination is performed by combining the first photoreceptor 4 and the second photoreceptor 4.
This can be done accurately by correctly setting the timing of the photoreceptor 25 and the conveyor belt 20. .

As shown in Figure 12, the manuscript with a small copy area can be used as the first manuscript, and the manuscript with a large copy area can be used as the second manuscript, as shown in Figure 12. It is possible.

As shown in FIG. 12, a case has been described in which the copy range of the first original and the range to be combined (erase range) of the second original match, but they may not match. In this case, based on the copying by the first original, that is, based on the copying range or erasing range by the second image forming device, the entire erasing range or copying range of the second original is determined in the manner shown in H above, and the copying range in the first original is Or convert it to the erased range. Then, the position of the copy image of the second original is changed and the copy image of the first original is combined with the copy image of the first original, and the combination can be performed in the same way as in the case where the copy range of one and the erase range of the other match. . In this case, the original whose copy area is not to be moved is set as the first original and transferred to the second image forming device by the second photoreceptor 25.
image is created, and the original that causes a 1:: movement between the copy range of the original and the copy range of the recording paper is used as the second original, and the first image is created -1.
It is convenient to perform multi-coordinate copying at different locations. In the opposite case, a part of the range of the original to be copied may be shifted outside the range of the recording paper.

In the case of composite copying of these two originals, in addition to using the same color developer in the first image forming device and developer in the second image forming device, it is also possible to use developers with different tones. For example, one If one is red and the other is black, it is possible to obtain a composite copy in which the red image of one original and the black image of the other original are combined.In other words, two-color copying is possible.The first method is also possible, but both It is also possible to configure the developing device to switch between black developer and another color, for example, red developer.In this case, for example, if you want to change the color tone based on black, the first The color of the developer in the image forming device and/or the second image forming device can be changed.For example, the color tone conversion key 50/and/or 50ft on the main operation panel can be used.
.

It is easier to control if the color tone of the developing devices 13 and 28 is changed to another color when turned ON.

In the above explanation, when copying by specifying the copying range or erasing range of one original, the first image forming device is used.
Although an example in which an image is formed using the first photoreceptor 4 has been described, it is of course possible to form an image using the second photoreceptor 25 by a second image forming device. When making a large number of copies, if the first image forming device is used, it is necessary to repeat the exposure scan of the document many times, and there are problems in terms of wear and vibration of the movable parts and other energy losses, but the second image forming device is used. The exposure optical system can be used to store images in a buffer memory and output electrical signals of the images multiple times; It is possible to make multiple copies by rotating only the second photoreceptor multiple times with only one reciprocating movement.

This is advantageous in terms of wear and tear on moving parts, vibration, and energy consumption.

In contrast to the configuration in which the first image forming device directly exposes an image to the photoreceptor as in the example shown in Fig. 1, the second image forming device has the same structure as shown in Fig. 18. It is also possible to have a structure in which the photoreceptor is stored and exposed to the photoreceptor using an LED and a converging light transmitter array. In this case, the lens 6 of the first optical system and the fourth mirror 1 in FIG.
The half mirror 52 of the zero and second optical systems is omitted, and both the first image forming device and the second image forming device form an image on the image sensor 54 by the lens 53, and depending on the image, the LED 32 of the first image forming device The control device can be configured to output either of the L E D 32' and the L E D 32' of the second image forming device. In FIG. 18, parts of the optical system of the first image forming device that correspond to the optical system of the second image forming device are distinguished by adding ``'' to the reference numerals.

In the example shown in FIG. 18, image data from one document is read by the COD of the image sensor 54, and is output to the first image forming device to form an image on the first photoreceptor 4, and the second image forming device ”, L j , !: ,

In this way, it is possible to color-code the image of one original and obtain a two-color image copy.

According to the present invention, two types of information, for example, two original images, one
It has become possible to combine and record a sheet of original and recorded information based on electrical signals from the outside as two-color images of mutually different tones at designated arbitrary positions.
