Description

TECHNICAL FIELD The present invention relates to a copy position setting method for setting and copying an image of a document at a desired position on copy paper during a copying operation.

The original manuscript is illuminated by an illumination device that moves relative to it, exposing the photoreceptor to form an electrostatic latent image, which is then turned into a visible image using toner, and the image is transferred to copy paper. Copying devices for transferring images are well known in the art.

When copying a document using the above type of copying apparatus, it would be advantageous if the relative position between the image on the document and the visible image on the copied copy paper could be changed to a desired state.

Furthermore, when necessary images on a plurality of documents or one document are to be compositely copied, it is often necessary to change the above-mentioned relative positions.

1. The present invention has been made based on the above recognition, and its purpose is to provide a simple structure for improving the visibility of the copy paper in the conveyance direction of the copy paper conveyed to the photoreceptor and in the direction perpendicular to this. It is an object of the present invention to provide a copying position setting method that allows easy adjustment of at least one of image forming positions.

1. The present invention adjusts the position of a document during copying using a 1-position setting means, thereby adjusting the visible image forming position on the copy paper in the conveyance direction of the copy paper conveyed to the photoreceptor and in the direction perpendicular to this direction. The structure is characterized by setting the position of at least one of the above, and the position of the visible image relative to the copy paper can be adjusted with a simple structure.

Hereinafter, a specific example in which the method according to the present invention is applied to a composite copying apparatus capable of compositely copying original images will be described with reference to the drawings.

FIGS. 1 to 4 are diagrams illustrating composite copying apparatuses, respectively, and for understanding the present invention, the configurations of these apparatuses will be explained. In FIG. 1, a document 100 placed on a document table 1 made of contact glass, for example, is optically scanned by an illumination device M (lamp) 2 that moves in the direction of the arrow.

A first optical system 8 having mirrors 3, 4, 5.6 and an imaging lens 7 irradiates light reflected from the original onto a photoreceptor 9;
The original image can be formed here.

On the other hand, a swingable switching mirror 10 provided in the optical path of the first optical system 8 deflects the reflected light beam from the original before it reaches the imaging lens 7, and a lens 11 converts the photoelectric conversion means, for example, arranged in a linear manner. It is also possible to form an image on CGDI2. A switching mirror 10, a lens 11, and a CCD 12. This constitutes a second optical system 13 that converts the original image into an electrical signal.

A display section 14 that displays images based on electrical signals from the second optical system 13 is provided, for example, a digital image display device such as a CRT or liquid crystal.

Similar to an ordinary copying machine, a photoreceptor 9 rotating counterclockwise has its surface uniformly charged by a charger 15, and the first
When the original image is formed on the photoreceptor by the optical system 8,
An electrostatic latent image is formed on the surface of the photoconductor, and when this latent image passes through the developing device 16, it is turned into a visible image by toner. The image is transferred onto paper 200 by transfer charger 17 .

The copy paper after the transfer is separated from the photoreceptor 9 by the separation charger 18, fixed by the fixing device 21, and discharged to the paper discharge tray 22.

In the case of composite copying, after the first visible image is transferred and fixed,
The copy paper 200 is temporarily stored in a buffer tray 24 by a route change guide device (for example, a switching guide member) 23.
``The second image, and the third and subsequent images are transferred and fixed onto the copy paper sent out from the buffer tray 24.

FIG. 2 shows the second optical system 13 in contrast to FIG.

According to this configuration, the document image can be displayed on the display section in real time.

FIG. 3 shows an example of a composite copying apparatus having a semi-automatic or fully automatic automatic document feeder 27, in which the first optical system 8 is formed in the same manner as in FIG.
Before feeding the original 100, a second optical system 13 having a video camera 26 (or C0D arranged in a planar manner) provided separately on the entrance side of the copying machine enters a reading area.
The document 100 is configured to be fed by the front feeding device 28. That is, after being read by the second optical system 13, the original is sent onto the original placing table 1, where it is illuminated and scanned by the first optical system 8. The other parts are the same as those in FIG. 1 and will therefore be omitted.

FIG. 4 shows a composite copy in which a CCD 12 is arranged in a line under the paper path at the entrance of the automatic document feeder 27 shown in FIG. Show the device.

Some examples of composite copying by the above-mentioned copying apparatus are as follows.

FIG. 5 shows an example of combining two or more original documents.

In FIG. 5(A), a part a of the first original 100 is erased and a part of the second original 101 is moved to that part or to the blank space a from the beginning and composited, and a composite copy paper 200 is created. create. In this case, a portion of the second original 101 is enlarged or reduced as necessary.

In FIG. 5(B), the images of the first original 100 and the second original 101 are arranged to form a composite copy sheet 200. .

FIG. 5(C) shows the first original 100, the second original 101, and the third original
A composite copy paper 200 is created by combining each image of the original 102 and the fourth original 103.

FIG. 5 shows only one example, and various types of synthesis are possible according to this example.

FIG. 6 shows an example of obtaining a copy by changing the arrangement of each part of one original document 100. When copying, each part can be enlarged or reduced in part or in its entirety.

(The case of the example shown in FIG. 5(A) will be explained.

In the apparatus shown in FIG. 1, the illumination device 2 performs preliminary scanning, and the second optical system 13 is used to scan the first
An image of the original 100 is displayed on the display section 14.

The display unit 14 displays a copyable range on the original image based on the selected copy magnification, copy paper size, and direction. By displaying the copyable range, selection conditions can be checked and corrected, and copy mistakes can be prevented in advance.

A frame is specified for the image area of the first original 100 to be copied using a cursor on the display screen, a light pen, etc., and whether the area to be copied is inside or outside the frame is specified.

Furthermore, copying conditions such as magnification and density are input.

As a result, the necessary image area and copy conditions for the first original 100 are stored in the memory, and copy preparation is completed.

During the above simulation prior to copying, the first
In the figure, the switching mirror 10 is in the state shown in FIG. 1, and the switching mirror 10 is in the state shown in FIG.
0 rotates out of the optical path.

A configuration as shown in FIG. 7 is used as a control section for selecting and storing each copying condition such as density during simulation. In Figure 7, CGD C line CC arranged linearly
D) 12 and a video camera 26 or C arranged in a plane
CD (plane CCD) is shown, but in the examples shown in Figures 1 and 4, line CCD 12 can be used.
It is possible to have a configuration having only the following. Further, in FIGS. 2 and 3, a video camera 26 (or a surface CCD) is used.

Information from the second optical system is converted into a digital signal by an A/D converter 50, processed by a DMA controller 51 and stored in a memory 52, and necessary arithmetic processing is performed by a microcomputer system 53. Further, the information content displayed on the display unit 14, which is made up of, for example, a CRT, is stored in the VRAM 54-, and the same content is stored in the CR.
It is controlled by the T controller 55 and displayed on the display unit 14.

When the copy start button is pressed, the copying process is started, and the illumination device 2 performs a scanning motion relative to the document on the document table, and the image of the document is formed on a photoreceptor rotating counterclockwise. As described above, a visible image is formed on the photoreceptor, and this is transferred to copy paper.

Since the relative position of the image displayed on the display unit and the visible image obtained by the copying process is the same, the unnecessary image part of the document is charged by a command from the control unit that stores the copying conditions. By controlling at least one of the device 15, the erase device 29, the developing device 16, the transfer charger 17, etc., it is possible to prevent an image from being formed on the copy paper.

For example, when controlling an erase device 29 in which LEDs, each of which can be turned on and off independently, are arranged in a line, the erase device 29 moves the photoreceptor between the charger 15 and the exposure position by the first optical system 8 ( (or rotation) direction, and in the example of FIG. 5(A), part a is erased. As the photoreceptor 9 charged by the charger 15 moves, portions of the erase device 29 corresponding to portions outside the image area on both side edges of the original are turned on, thereby dissipating the charge outside the image area on the photoreceptor 9. When the part a comes, press L of the erase device 29.
The ED is turned on only in the range of the part a and outside the image, and releases the charge outside the image and the part a. When the part a passes, the LED
turns on only outside the image on the photoconductor and releases the charge.

Since the portion from which the charge has been released by the erase device 29 is not visualized even after exposure and development, an image in which the portion a is erased as a blank is obtained on the copy or paper.

The copy paper on which the image has been transferred and fixed is stored in the buffer tray 24 by switching the path conversion guide device 23. When one sheet or a predetermined number of first originals have been copied, a second original 101 (FIG. 5(A)) is set on the original placing table 1, and the second original 101 (see FIG. The two optical systems convert the signal into an electric signal and display the image on the display section 14. In exactly the same way, the portion of the second document to be copied is specified. Display section simultaneously with displaying the image of the second document or by instructing with the key.
In I, the stored area designation frame of the first document and the image of the necessary portion of the second M document are displayed in a composite manner.

As in the case of Fig. 5 (A), if the positions of parts a and b of each original are shifted, the image of the necessary part of the second original will be displayed in the designated frame of the first original Adjust the position so that it appears. At this time, the amount of movement of the required image on one display section is stored. The display image size of the required image of the second manuscript is
Changes by changing the set magnification. in this way,
The control circuit is configured so that when the magnification is changed, the specified frame of the second document is enlarged or reduced, but the specified frame of the first document does not change. Note that, if necessary, only the specified frame of the first document can be enlarged or reduced.

When the copying conditions for the second original with respect to the first original are selected through simulation on the display unit, the copying of the second original 101 is performed by pressing the copy start button.

At this time, the copy paper stored in the buffer tray is registered by the registration roller 25, a visible image is transferred from the photoreceptor 9, and fixed by the fixing device 21, and then placed on the paper output tray.
2.

At the time of image creation, it is necessary to move the image of the necessary portion of the second document to the editing position, and the required amount of movement has already been described.

This is the amount by which the image is moved on the display unit or the amount corresponding to this when simulated as shown in FIG. In the example of Fig. 5(A), Fig. 8(A)
As shown in FIG. 8, the necessary images of the original 101 are arranged in the direction of conveyance of the copy paper 200 conveyed to the photoreceptor, that is, the moving direction P of the photoreceptor (X (FIG. 8 CB)), and the direction perpendicular thereto (Y (eighth) (Figure (C)) It is necessary to shift the image and copy it onto the copy paper 200.

To shift the original image in the X direction, the shift X can be adjusted by adjusting the timing of the rotation start of the registration roller 25 as shown in FIG. When the copy paper is 200',
(The copy paper used when shifting is indicated by 200). That is, the copy paper 2 onto which the visible image b1 formed on the photoreceptor 9 is transferred
The rotation start timing of the registration roller 25 is delayed so that 00 is at a position X later than the copy paper 200'. In this way, the copy paper 200 is not misaligned.
′, the visible image b1 on the photoreceptor is transferred to the position indicated by b2, whereas the visible image b1 on the photoconductor 200 is transferred to the position indicated by b3, which is shifted by X from b2. A visible image is transferred. Furthermore, by advancing the rotation start timing of the registration rollers 25, the image can be moved to the opposite side. Furthermore, when fixing the document table 1 and illuminating the document on it, as shown in FIG. The normal position (that is, the position when the image is not shifted) is changed to a position advanced by X as shown in 2, and at this time, the rotation timing of the photoreceptor and the feeding timing of the copy paper remain as normal. In this way, the visible image is placed on the photoreceptor 9 at a position b5, which is further forward by X in the direction of rotation of the photoreceptor than the visible image position b4 that is formed when the illumination device is started from the position shown by 2'. An image can be formed, so that a visible image is formed on the copy paper at the position shown in FIG. 8(B).

Alternatively, the photoreceptor 9 can be moved without changing the starting position of the illumination device.
Alternatively, the illumination start timing of the illumination device may be changed with respect to the movement timing of the transfer paper, and the exposure start timing of the photoreceptor may be changed. Namely.

If illumination of the document is started earlier than when the image is not shifted, a visible image can be formed at the advanced position b5 on the photoreceptor, as in FIG. 1O, and the copy paper 20 shown in FIG.
0 is obtained. In an apparatus in which the document is illuminated while moving the document tray, the start position of the document tray is not changed, but the start timing of the document tray is shifted relative to the movement timing of the photoconductor 9 and the copy paper, and the exposure start timing of the photoconductor is changed. The same result can be obtained by changing .

Furthermore, by stopping the photoreceptor during exposure, the exposure timing for the photoreceptor can be controlled and the deviation X of the visible image in the direction of movement of the photoreceptor can be adjusted.

By adjusting the start position of the illumination device and its start timing in the opposite direction to the above-mentioned direction, the image can be shifted in the opposite direction.

As shown in Figure 8 (C),
The method of shifting is to move the imaging lens 7 in the direction of the shift Y.
As shown in FIGS. 1 and 1, the position of the imaging lens may be moved by Y/2 from the normal position 7' in the direction perpendicular to the optical axis, as shown by 7. By moving the lens in the opposite direction, you can shift the image in the opposite direction. Furthermore, by making the photoreceptor movable in a direction perpendicular to the copy paper conveyance direction, the position of one image can be shifted in the Y direction.

As mentioned above, it is possible to copy the original image by shifting it in the conveying direction of the copy paper and in the direction perpendicular to this using various methods, and it is possible to move the image in any area of the original to any position on the copy paper. The present invention differs from the above-mentioned method and proposes an extremely simple configuration in which the stopping position of the document is adjusted as illustrated below.

First, the case where the copy paper is shifted by X in the conveyance direction will be explained.

The automatic document feeder 27 as in the example of FIGS. 3 and 4
When using , as shown in Fig. 12, the second original 101 whose image position is to be shifted is stopped on the original platen 1 (shown in Fig. 12; see Figs. 3 and 4). The position of the original 101' is set to
the front (to the right of the diagram). In this way, even if the start position of the illumination device 2 and the actuation timing of the photoreceptor 9 are left as normal, the photoreceptor 9 obtained from the original 101 can be
The upper visible image b5 can be advanced by X in the direction of rotation of the photoreceptor than the same visible image b4 obtained from the document 101' which is not shifted by one position, and if this image b5 is transferred to copy paper, the eighth A visible image can be formed at the position on the copy paper shown in Figure (B).

Conversely, document 1 is sent at a position X ahead of document 101'.
01, it is possible to obtain a copy sheet with the visible image moved to the opposite side.6 In the above configuration, the automatic document feeder 27 itself is used as a position setting means for setting the position of the document at the time of copying. ,
There is no need to add special means, and the configuration can be simplified. In this case, in order to stop the document after shifting it by a predetermined amount When a document is sent by the roller, an appropriate configuration known per se may be adopted, such as controlling the operating time of the roller.

Further, as shown in FIG. 13, in another embodiment of the present invention, in a copying apparatus of a type in which the illumination device 2 is fixed and the document placed thereon is illuminated while moving in the direction of the arrow,
The original placing table 1 when the original 101 to be copied is placed with the position of the original image shifted than the original placing table 1' when the original 101' is placed without shifting the original image.
is moved to the right from the position advanced by X in the direction of the arrow.

With this, as shown in the lower part of FIG. 13, the photoreceptor 9 and therefore the copy paper 200 are
The position of the upper visible image can be shifted (Figure 8 (B)
)). By starting the document table from a position shifted in the opposite direction to that shown in FIG. 12, the visible image can be shifted in the opposite direction.

In the configuration shown in FIG. 13 as well, the document table that moves to scan the document can be used as the document position setting means, and there is no need to add any special means.

Furthermore, even in a type of copying machine where the document placement table is fixed during illumination scanning of the document, the placement table is supported movably in the X direction relative to the copying device body in order to set the position of the document. Move the image position arbitrarily in the X direction,
It is also possible to configure the copying position so that it can be freely adjusted.

Further, in the present invention, as illustrated below, the original image is copied by shifting it by Y in the direction orthogonal to the conveyance direction of the copy paper.

That is, if an automatic document feeder that can feed the document in the direction of the deviation Y is provided, as shown in FIG.
Set the original stopping position on the original platen 1 to the normal position (101
) is the state (1
01). P in FIG. 14 indicates the conveyance direction of the copy paper. As a result, copy paper in the state shown in FIG. 8(C) can be obtained. Even in this configuration, the document feeder itself is used as a document position setting means.
(Although this can simplify the configuration, it is also possible to set the position of the original by providing special means for adjusting the stop position of the original.

Also, although not shown in the figure, the document placement table is supported movably in the Y direction, and by moving the document placement table, the position of the document on it can be adjusted and the image position can be arbitrarily changed in the Y direction. You can also do that.

In the configurations shown in FIGS. 12 to 14, in order to shift the document placing table by a predetermined amount, for example, a stepping motor may be used to accurately move the document placing table.
Alternatively, it may be moved manually. When manual operation is performed, a scale may be attached to the main body of the copying apparatus or the original table so that the amount of movement can be visually observed.

Furthermore, it is advantageous to be able to display the movement status of the mounting table on the display section 14, regardless of whether it is manually operated or automatically operated.

Note that even when the lighting device is moved, it is preferable to operate the lighting device in the same manner as the above method, or to display its status on the display unit.

By combining the above methods of adjusting the deviation X and adjusting the deviation Y, it is possible to form a copy image of each original at a predetermined position on the copy paper, that is, at the edited image position. In this case, if the document placement table is supported so that it can be moved in both the X and Y directions, the document image can be moved in both the X and Y directions by simply moving the document placement table. It is particularly advantageous to be able to form a visible image on copy paper.

Erasing unnecessary portions of the second document is carried out in accordance with instructions from the control section, as in the case of the first document.

As a result, a copy image in which the first original and the second original are combined, that is, the same edited image as previously displayed on the display unit, is obtained as shown by copy 200 in FIG. 5(A).

The composite copy paper is discharged from the paper discharge tray 22 because the path change guide device 23 is switched after fixing.

By the switching control of the route change guide device 23, the copy paper on which the second original has been copied is stored in the buffer tray 24 again, and the original images from the third original are compositely copied onto this copy paper, and finally the copy paper is By discharging the images onto the paper discharge tray 22, a composite copy of multiple original images can be easily obtained.

For your reference, in addition to the above method, the composite editing of the second manuscript and the first manuscript is the same as the simulation and copying of the first manuscript. The display section 14 displays only the necessary portions of the image and the second document stored in the same manner as above on the display section.
However, there is also a method in which the originals on the original table are moved by hand so that the designated frames of both originals match. In this case, the image magnification and image density can also be selected while looking at the display section. When copying the second original after the simulation, since the movement of the necessary part of the second original to the editing position has already been performed by moving the second original, the control as shown in FIGS. 9 to 14 is used. By forming an image on the photoreceptor without performing any process and transferring it to copy paper from the buffer tray, the same as the edited image can be obtained as a hard copy. Other procedures are the same as those described above.

When a line COD is used as the second optical system, it is necessary to scan the illumination device by at least the size of the document in order to read the image with the CCD.

Therefore, when adjusting the position by manually moving the original while looking at the display section, editing adjustment cannot be performed unless the second original is scanned each time the second original is moved, which takes time. Therefore, a document mounting table 1 made of contact glass or the like is supported movably in the X and Y directions, and the second document is first aligned with the rough edge, and the image of the document is read by the COD and displayed on the display section. Based on this, the deviation of the second original from the predetermined position is determined, and then the original placing table 1 is moved by this amount in the X and Y directions to set the second original at the predetermined position. Then, the image display of the second JJ5f document on the display section is moved in accordance with the amount of movement of the document table 1 at this time. In this way, the scanning movement of the optical system for editing positioning is 1
It only takes a few times.

The copying apparatuses shown in FIGS. 2 to 4 can also perform copying and synthesis according to the example in FIG.
(Instead of reading the image with the CCD 12 shown, the same operation may be performed with the video camera 26 shown in FIGS. 2 and 3, or with the COD shown in FIG. 4. Since the original image can be displayed in real time, this operation can be performed particularly easily when manually aligning the second original.

When the copying magnification is changed, the magnification of the image on the display section can also be changed accordingly.One method is to change the optical magnification in the second optical system 13, and the other is to change the optical magnification without changing the optical magnification and read the image by the second optical system 13. There is a method in which the electrical signals of the image are processed and the display unit displays an image whose size changes in proportion to the change in copying magnification. Furthermore, when the copying magnification is changed, there is also a method in which the size of the image on the display section is kept constant and the frame indicating the copyable range is enlarged or reduced in accordance with the copying magnification.

It is also possible to simulate a predetermined copy density from the original image displayed on the display unit. The original image read by either of the A
The microcomputer system 53 converts this A/D converted value into a stored value (
After performing image processing, the image is displayed on a display unit (CRT) 14. The value stored in this microcomputer corresponds to the copy image density, and since simulation can be performed using the image density on the display section 14, error-free copying is possible.

The density adjustment of the copying apparatus can be performed by changing at least one of the exposure amount, the charging amount, the developing bias voltage value, etc.

In addition to the normal display, the display section can also be configured to display various operations using the operation section, and can be used to monitor the jam position, display the user's manual, and display the contents of a serviceman call (logging function). be able to.

When copying and synthesizing, the copying and combining of a single document sheet shown in FIG. 6 can be performed in exactly the same manner as the copying and combining of a plurality of sheets described above.

In this case, for example, the images may be sequentially displayed on the display section without changing the document, and composite editing may be performed.

As described above, the composite copying apparatus to which the present invention can be particularly advantageously applied includes an illumination device that optically scans a document on a document table, and at least one lens that forms a light image of the scanned document on a photoreceptor. a first optical system having a photoelectric converter, a second optical system having a photoelectric conversion means for photoelectrically converting an original image, a control unit that processes an electric signal from the second optical system, and a control unit that processes an electric signal from the second optical system; A specific example will be described in which the present invention is applied to a copying apparatus having a display section for displaying an image, a means for indicating a reproduction area on the display section, and a means provided in the control section for storing and processing the instruction contents of the instruction means. However, it goes without saying that the present invention can also be applied to other appropriate copying apparatuses.

According to the present invention, a visible image is transferred onto a copy paper in at least one of the conveyance direction of the copy paper conveyed to the photoreceptor and the direction perpendicular to this by an extremely simple configuration of adjusting the position of the original. It is now possible to freely set the position.
