Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an analog image editing copying machine that extracts necessary parts of a plurality of original documents in an analog manner and edits them onto a single sheet (transfer paper).

2. Description of the Related Art Various copying machines are known that are equipped with a so-called analog image editing function that extracts necessary portions of a plurality of original documents in an analog manner and edits or combines them onto a single sheet (transfer paper).

Conventionally, this type of copying machine uses a first document with a hole in the area where the second document should be inserted, and overlaps this and the second document to copy it as one document, or
W. Once the original is copied, the sheet is stored in the sheet storage section inside the machine, and when copying the second original, this sheet is re-sent to the transfer position, and the necessary part of the second original is copied on the same surface as the copying surface of the first original. There are some known things to do.

In the latter copying machine, an exposure relative position adjusting means and an erasing means are used to align each original document.As described above, the concept of image editing in conventional composite copying apparatuses has become publicly known. However, there are technologies to improve operability, or even graphics! Nothing specifically disclosed the various functions involved in editing.

Furthermore, in the past, when attempting to set the d and both regions, a large number of switches were required, resulting in an expensive device.

Purpose The present invention is based on the conventional example of Yoikei, and its purpose is to improve the function of picture editing and the operability of the picture (III) collection input section.

composition Hereinafter, the configuration of the present invention will be explained based on the drawings.

First, the functions of a copying machine, which is the premise of the present invention, will be explained based on FIGS. 1, 2, and 3, and then the present invention will be explained with reference to FIGS.

In FIG. 1, the first document set at a predetermined position by the document changer is illuminated by a well-known illumination exposure optical device 8 including a light source 2, mirrors 3 to 6, and a lens 7, and a photoreceptor 9 is exposed to carbon dioxide. exposed to light.

The photoreceptor 9 is uniformly charged by a charger 10, and its nine surfaces are exposed by an illumination exposure optical device 8 to form an electrostatic latent image. While the photoreceptor 9, for example a photoreceptor drum, is moving, the electrostatic latent image is developed and visualized by the developing device 1.

The image of the photoreceptor 90 is transferred to a transfer paper 14 serving as a copy paper fed from a paper feed section 12.13 at a transfer position.

In FIG. 1, a transfer drum 15 is used as a means for conveying the transfer paper 14 to the transfer position.

After the transfer, the photoreceptor 9 is neutralized, cleaned by a cleaning device 16, and the process from charging is repeated again.

The transfer paper 14 on which the image of the first original document has been transferred is sent to a storage device. In FIG. 1, the transfer drum 15 is also used as a storage device. Therefore, the transfer paper 14 fed from the paper feed section 12.degree.
Flanged by 17.

After the transfer paper 14 is flanged by the transfer drum 15 and rotates once to transfer the image of the first original from the photoreceptor 9, it is temporarily fixed to the transfer drum 15 at a position where it does not contact the photoreceptor 9. stored.

There is a method of changing the distance between the transfer drum 15 and the photoreceptor 90 in order to keep it in a non-contact state with the photoreceptor 9 during storage, or a method of providing a recess in the part of the transfer drum 15 where there is no transfer paper, and making the recess face the photoreceptor 9. There are many methods available to do this.

In the above process, the image of the first original is transferred to the transfer paper, and while the transfer paper is stored in the storage device, the original replacement device l
At , the first original is taken out and the 20th original is set at a predetermined position. Thereafter, the photoconductor 9 is charged, exposed and developed in the same steps as for the first document, and the second document formed on the photoconductor 9 is transferred to a transfer paper fed from a storage device, such as a transfer drum 15. By rotating it again, the image is transferred to the transfer paper 14, which is sent to the transfer position, on the same side as the first original. In this way, when images of a predetermined number of documents starting from the third document are transferred and combined onto the same side of one transfer sheet, the transfer sheet 14 is unflangeed, fixed by the fixing device 18, and placed on the output tray 19. is discharged.

The document exchange device 1 is simply attached to the copying machine's copying glass 20.
Alternatively, a semi-automatic document handling device or a fully automatic document handling device having a feed belt 21 that feeds and sets manually inserted documents to a predetermined position may be used. . ' In FIGS. 1 and 2, the transfer drum 15 is also used as a storage device for transfer paper after the self of the first original is transferred until the second original is transferred. Therefore, when transferring the image of the second original, the photoreceptor 9 is used to adjust the deviation in the transfer paper feeding direction between the composite position of the first original and the information position of the second original by the transfer timing of the transfer paper. The photoreceptor 9 is rotated with a desired timing shift relative to the rotation of the transfer drum 15. At this time, in order to avoid slipping between the photoreceptor 9 and the transfer drum 15, the transfer drum 15 is rotated at the stop position of the transfer drum 15.
Either the transfer drum 15 is formed with a concave portion facing the photoconductor 9 to avoid direct contact with the photoconductor 9, or when the transfer drum 15 is stopped, the photoconductor 9
It can be a structure that moves away from the target.

The storage device can be provided separately from the transfer drum 15 instead of being used as a storage device. For example, as shown in FIG. 2, the transfer paper is sent from the paper feed section 12.13 to the transfer position by the photoreceptor 9 by a transfer paper conveying means 27 having a roller 22 and a guide 23. After the transfer paper is transferred by the means described above, the transfer paper is fixed by the fixing device 18 and then sent to the storage tray 30 through the storage path 29 which is switchably provided by the first gate 28 with respect to the path to the paper discharge tray 19. When feeding the paper into the storage tray 30, it is always turned upside down so that the leading end is fed as the leading edge, and in the illustrated example, the paper is fed and stored with the copy side facing down.

After one copy or a predetermined number of copies of the first original are stored in the storage tray 30, the second original is copied. In the figure, a document exchange device 1, an illumination exposure device 8,
The related parts of the photoreceptor 9 are the same as those in FIG. 1, so their explanation will be omitted.

When copying the second original, the paper is fed to the storage tray 30 in advance according to the exposure timing or stopped by the paper feed roller in the storage tray 30 and the reso roller provided in the middle of the transfer paper conveying means 27. The rotational drive of the resolution roller is performed under timing adjustment according to the positional deviation calculated by the composite position signal and the information position signal, so that the composite position of the transfer paper carrying the first original is determined by the rotation of the photoreceptor 6. Adjustment is made so that the image of the information of the second document formed on the photoreceptor 9 is exactly at the transfer position when the position is changed. The transfer paper is stored in the storage tray 30 in a number corresponding to the number of originals to be combined, and then sent again to the transfer position of the photoreceptor 9, and is repeatedly fed in a circular manner.

When the composite copying of the final original is completed, the transfer paper is discharged to the paper discharge tray 19 by switching the first gate 28 .

In FIG. 2, another second gate 31 is provided from the fixing device 18 to the first gate 28, and the transfer paper is sent to the storage tray 30 through the first gate 28 in an inverted state. In other words, without being reversed after passing through the fixing device,
In the figure, a switching path 3'2 can be provided for feeding the copies into the storage tray with the rounded side up and the front end facing the rear end. By switching this second dart, the switching path 32
When the transfer paper is sent to the storage tray 30 through the transfer paper, in the next copying process, the opposite side of the transfer paper contacts the photoreceptor and is transferred. In other words, double-sided copying becomes possible.

By providing two Goo (28.31) and switching the transfer method to the storage tray, composite copying, double-sided copying, and even double-sided composite copying are possible. can do.

That is, double-sided composite copying is possible by performing the above-mentioned composite copying operation on one side, then feeding it to the storage tray 30 from the second goo 31 through the switching path 32, and then performing the above-mentioned composite copying operation again on the back side. .

Incidentally, in FIG. 3, 33 is a sorter, which can be connected to the copying machine in place of the paper discharge tray 19 in FIG.

Next, FIG. 4 shows the operation section of the copying machine according to the present invention, and the operation mechanism will be explained with reference to this figure. The operation keys are 10 keys (
1 to 9.0) 34, interrupt key 35, clear/stop key 36, print key 37, density adjustment key 38,
Standard mode setting key 39, paper feed selection key 40, magnification setting key 41, double-sided copy key 4 for double-sided originals and single-sided originals
2. There are a stack key 43, a sort key 44, a left blank key 45, a right blank key 46, a reverse paper ejection key 47, and a composite copy key 48, which are not normally visible on the display section 49.50, but are shown in the figure when lit. A message similar to that shown below will appear.

When copying, it is best to use the keys on the left side of the operation unit, and the functions will be explained starting with the keys on the left side.

The left blank and right blank keys 45 and 46 are keys for adjusting the binding margin, and set the binding margin to 15 mm on the left side of the copied transfer paper.
-If you want to create, hold down the left blank key 45 and press
When 15 is input using the 10 key 34, the 7-segment display at the top of the display section 49 lights up as 15''. This may be blinking, and when the left plank key 45 is released, 15'' disappears and returns to 1#. The same applies to the right blank key 46.

The composite copy key 48 is used when it is desired to copy the first original and the second original in an overlapping manner.

The reverse paper ejection key 47 is used when you want to turn the copy paper upside down and output it to the paper ejection tray 19. When copying from the first original, the ejected transfer paper is one sheet with the bottom side facing out. Since this is a side-by-side copy, if you turn it upside down, you can simply flip over the many ejected transfer sheets and align the pages in order starting from the first sheet.

The stack key 43 and sort key 44 are well known and need no explanation.

The double-sided copy keys 42 for double-sided originals and single-sided originals are used when double-sided copying is desired, and there are two cases: double-sided copying from a double-sided original, and double-sided copying from a single-sided original.

The paper feed selection key 40 is used to select the paper feed trays (12, 13), and the display section 49 indicates that the first paper feed tray is A4.
However, the second and third paper feed trays each have B4. A3
is set, and when the first row is selected, the A4 display area is surrounded by a frame. If the user wishes to select the second row, press the paper feed selection key 40 to move the frame to the second row and select the second row.

To set the magnification, there is an enlargement key and a reduction key (magnification setting key 41).If you press them, for example, 1%
It is displayed on the display section 49 in increments. And for example 7
When "1%" is displayed, "A3→A4" is also displayed to notify that the magnification is to reduce A3 to A4.

The 10 keys 34 from 1 to 9,0 are used to set the number of sheets, and are displayed in the upper seven segments of the display section 49.

The lower 7-segment display is for displaying the number of copies. Further, as described above, it is also used when setting the binding bar width using the 10 key 34 while pressing the left and right blank keys 45 and 46 for adjusting the binding margin. Although there are enlargement and reduction keys in the figure, it is also possible to use this as one magnification key and input a desired value using the 10 key 34 while holding down this magnification key.

The interrupt key 35 is used when an emergency copy is required during copying; pressing it will interrupt Sicobee, and pressing it again after performing the emergency copy will cause
You can return to the previous mode and resume copying.

The explanation of the clear/stop key 36, density adjustment key 38, and print key 37 will be omitted.

The standard mode setting key 39 is used to change to the set mode by pressing it, for example, A4.
If you set the magnification of Loom (life size) in the size, the mode used by the previous person is A3 size with a reduction rate of 71 inches,
If you are in the sort mode for double-sided copying, you can change the magnification to 100 inches for A4 size by simply pressing the standard mode setting key 39 to save yourself the trouble of canceling these settings.

The above is an explanation of the keys, and in the case of the figure, an example is shown in which the left blank, right blank keys 45, 46, composite copy key 48, and reverse sheet ejection key 47 are covered because they are not keys that are always used. .

Next, the display functions of the display units 4 (1, 50) that have not been explained yet will be explained.

A display 4901 is lit when the original and the transfer paper do not match, and the determination is made, of course, including the magnification.

Display 4903 lights up when there is no paper in the paper feed tray.

A display 4903 lights up when copying the back side of a double-sided copy.

Display 4903 is displayed when there is transfer paper in the printer bin.
This book lights up when you press the stack or sort key to warn you not to mix it with previously copied transfer paper.

Display 4904 is a display warning of forgetting a document.

Display 4905 lights up when interrupt key 35 is pressed.

002, the warm-up has been completed and the print key 37
Lights up when pressing starts copying.

Display 5003 is displayed numerically when there is an abnormality in the machine, and at this time display 5004 also lights up to indicate if there is a problem with the machine. It becomes a sman call. This number allows you to see where the abnormality is.
It has the meaning of self-diagnosis. It can also be used to display the waiting time in minutes during the aforementioned warm-up.

Display 5005 lights up when the door is open. If the door on the sorter side is open, display 5005 will appear.

5006.5007 lights up.

Displays 5008 and 5009 light up when there is a jam, and in the case of a jam in the sorter, displays 5009 and 50
06 lights up.

Display 5010 lights up when the key counter is not set.

Display 5011 lights up when there is a shortage of toner.

FIG. 5 shows the operation section of the ADF, and will be briefly described.

On the operation panel shown in FIG. 5B, the ADF key 51 is used to automatically feed a document, and the 5ADF key 52 is used to manually insert a document, both of which are well known.

The size unification key 53 is a mode in which the size of the original is detected and the magnification is automatically set to match the size of the transfer paper in the selected paper feed tray. This is used when you want to unify.

The automatic paper feed selection (A, P, S,) keys 54 are used to detect the size of the original and automatically select transfer paper in the paper feed tray so that the set magnification is achieved. be.

The counter key 55 is used when you want to display the number of original sheets, and the number of sheets is displayed using a 7-segment LED.
56.

In the same figure (a), the K display/4' panel includes a document jam display 57 and a set confirmation display 58 that lights up when the document is incompletely set.If the document is set in the 5ADF mode, copying will start. Original feed display 59 that lights up when the status is
, and a document insertion display 60 that indicates the direction in which the document is to be inserted and turns off when the document is inserted.

Next, the display unit according to the present invention will be explained.

The display uses CRT.

The contents of the CRT screen are shown in FIGS. 6(a) to 6(g).

In the figure (,), 61 indicates the size of the transfer paper, and scales 61 and 63 indicate the size value of the transfer paper.

64 is a portion of the first manuscript. 65 is a portion of the second manuscript. Furthermore, 66 is a portion of the third original. The character display below the scales 62 and 63 indicates the mode content of each part of the original and the transfer paper size.

In figure (b), 64 is a copy of the first manuscript, 65
is part of the second manuscript. The first original is copied at the same size as indicated by the character display. The second original 65 is copied with a reduction of 93 inches as indicated by the character display.

In Figure (c), 64a and 64b are portions of the first (same document) document.

In Figure (a), 64 is a part of the first original, a frame is made on the transfer paper, and part 65 of the second original is copied in the 93 inch reduction mode into the area shown in the figure. A portion 66 of the third document is copied in 115% enlargement mode.

In the figure (,), 64 is a portion of the ]th manuscript. 65 is a portion of the second manuscript. 66 is a portion of the third manuscript. 65 and 66 partially overlap, but 65 is copied with priority. 64 is the same size, 65 is 93 inches reduced, 66 is 87%
It shows the position where the copied item can be shown by reducing the size of the image.

In figure (f), 64a and 64b are parts of the first original. 65 is a portion of the second manuscript. 6
4b and 65 have partial types as in the figure (,), but 65 is copied preferentially.

In Figure (g), 64m' and 64b are parts of the first original. 65 is a part of the second manuscript.

64b and 65 partially overlap, but 64a,
This is a case where it is necessary to copy both depending on the content to be copied to 64b (this is a case where no priority order is given).

Above, an example on the CR7 screen is shown in FIG. 6(, ) to rx>-i. If the CRT is a color type, it will be easier to see if, for example, the figure (-) is displayed with 64 in green, 65 in yellow, and 66 in red. If the CRT is not a color type, 64 is a solid line, 65 is a broken line, and 66 is a single dot. They can also be distinguished by dashed lines.

When there is a priority order as shown in Figures (e) and (f), the highest priority order is red, yellow, blue, etc., or a solid line,
It is also possible to use a predetermined line, such as a broken line or a chain line.

Figure (a) The numbers 64, 65, and 66 shown in K indicate the order of the originals. On a color CRT, the first document is
If you predetermine red, yellow for the second original, and blue for the third original, the numbers in 64, 65, and 66 will not be needed.

Next, the operation section for image editing is shown in the block diagram of FIG. The pressure-sensitive sheet 67, which uses a pressure-sensitive sheet to detect the position of the document, has signal lines on the X and Y axes for inputting and outputting each matrix signal, and position information is transmitted by the scan signal from the Z10 controller 68 in the block diagram. It is now possible to input.

The I10 controller 68 is connected to a host μepu, which will be described later, via a data bus. The original editing area is detected based on the scan timing signal of the pressed pressure sensitive sheet 67 and the matrix information of the scan return signal.

A group of keys 69 connected to the area operation section include an edit start key, an edit end key, a priority key, an area shift key, and (
It consists of keys (left, right, up, down), zoom keys (up, down), and color specification keys (black, red, blue).

To determine whether a key has been pressed, the scan signal for detecting the key code and the scan signal when the key is pressed are sent to the Ekacontroller 6.
According to the matrix signal of the return signal which returns to 8.

To explain the keys on the operating section, (1) - group start key is a key that notifies the start of editing of the original.If this key is not pressed, the position information of the pressure sensitive sheet 67 is canceled.

■ The editing end key is a key that notifies the end of editing the manuscript. When this key is pressed, all area designations are completed. If the editing end key is not pressed, multiple areas within the manuscript can be arbitrarily specified.

■ The priority key is pressed when specifying an area for a multi-page document and if there is overlap in the area, the priority key should be given to securing the area for the document. When this key is pressed before, after, or during area designation, a priority flag is set in the RAM that stores the number of originals.

■ The area shift key shifts the frame length of the specified area to the left, right, top, and bottom without changing the frame length.

The data in the y'-axis direction of the data contents of the area RAM MAP shown in FIG. 8 is changed, and the updated position data is stored when the shift key is released.

For the 691 and 692 keys, the data of the y-axis position of the RAM is updated.

With the 693 and 694 keys, the data of the X-axis position in the RAM is updated.

■Zoom key This key is pressed to change the size of the image within the area frame, and can steplessly instruct in the direction of enlargement or reduction.

■ The color designation key is a key that is pressed when creating multiple colors on copy paper.

■ The pressure sensitive sheet key determines the positional information of the editing area and is valid while the editing end key is pressed after the editing start key. Judgment based on matrix signal.

Scan all areas of yn and determine the position.

FIG. 9 is a diagram showing the pressure-sensitive sheet showing the X-axis and the y-axis, and FIG. 10 is a diagram showing a state in which transfer paper is placed on the pressure-sensitive sheet 67. The four corners inside the transfer paper are image editing areas. Also, Figures 11(a) and (b) are diagrams showing the area shift state, and Figure 12 is the R at that time.
This is AM Mazda. In FIG. 7, 70 and 71 are drivers, and 72 is a comparator.

Next, the optical illumination section will be explained.

One element for image editing is the conversion of my size and image position on the copy screen. In the analog image editing and copying apparatus to which this application pertains, this is achieved by an optical image projection device (optical system).

In the copying apparatus shown in FIG. 1, an original placed on an original placing glass 20 is illuminated by a light source 2, and the image of the original is projected onto a photoreceptor 9 in a slit shape by a group of mirrors 3 to 6 and a lens 7. .

Also, by scanning the first mirror 3 (velocity V) and the fs2 mirror 4 integrated with the light source 2 relative to the original,
The image of the original is continuously projected onto the photoreceptor 9.

K, which transforms my size, performs variable-magnification projection.

1) The magnification conversion in the mirror scanning direction is determined by the relative relationship between the surface speed v6 of the photoreceptor 9 and the first mirror scanning speed V. If the magnification is m, then m = 2 υ (This does not apply to full exposure copying machines such as flood exposure) 11) The magnification conversion in the direction perpendicular to 1) above (the axial direction of the photoreceptor drum) is performed by so-called zooming. .

In the example of FIG. 1, a fixed focus lens is used. Move the lens 7 in the direction of the optical path by an amount (Δ&) equal to the magnification mK, and move the lens 7 toward the optical path. -5,
This is achieved by displacing 6 and correcting the total path by Δt. If the focal length of the lens is f, then Δt = (m+1-2)f If a zoom lens is used, correction of the tortoise can be omitted.

Image position transformation is achieved by the following means.

i) The positional change in the mirror scanning direction is achieved by changing the relative positional relationship between the image and the transfer paper, that is, the timing of contact of the transfer paper 10 with the photoconductor during transfer of the toner image formed on the photoconductor. (The timing relationship between the photoreceptor and the transfer paper may be kept constant and the mirror scanning start timing may be changed.) 11) Image position conversion in the direction perpendicular to 1) above is achieved by moving the image in the direction perpendicular to the optical path of the lens. Achieved by projection position transformation.

FIG. 13 is a plan view of the lens optical path. In FIG. 13, when exposing information in a partial range a of a document range A, an image is normally formed on a partial range A of a range B of the photoreceptor. The photoreceptor corresponds to copy paper or transfer paper. Now, if the lens 7 is moved by - in the direction perpendicular to the optical axis, a partial area on the photoreceptor will be moved, so the distance t will be in the direction in which the lens 4 has moved.
The partial area b'lfm that has been moved is moved. That is, by selecting the amount of movement of the lens in the direction perpendicular to the optical path, it is possible to arbitrarily select the image forming position on the photoreceptor, particularly on the copy paper, in the direction perpendicular to the direction of movement of the copy paper.

If used in conjunction with magnification conversion by moving the lens 7 along the optical axis, variable magnification copying and composite copying can be performed at the same time. The amount of movement of the lens in the direction perpendicular to the optical axis is set by calculating the deviation between the information position and the designated copying position using a control device, and controlling the lens moving device using the signal obtained.

For example, the structure for moving the lens is shown in Fig. 14 and Fig. 1.
As shown in FIG. 5, a lens stand 73 to which the lens 7 is fixed is supported by a lens bracket 74, and the lens bracket 7
4 is screwed onto a screw shaft 76 which is rotatably supported by an optical system frame 75, and the screw shaft 76 is reversibly rotated by the motor 77 directly or via a belt or the like, whereby the lens 7 is rotated. Structures that move in a direction perpendicular to the optical axis can be used. If the movement of the lens bracket 74 is guided by a guide plate 4-78 fixed to the optical system frame 75, the lens can be smoothly reciprocated without tilting.

If the optical system frame 75 itself is screwed onto a threaded rod or the like in the same manner as shown in FIGS. 14 and 15 so as to be movable in the optical axis direction, magnification can be changed.

To convert the image position, in addition to the above-mentioned method of controlling the copy paper feed timing and lens movement, it is also possible to move the original together with the original placing glass in one direction or in two orthogonal directions to adjust the setting position of the original. You can also use this method.

Next, the control section will be described.

YI (β1.β2) and Yg (β1.β2) mean β1.
Each half of the erase element selection data is changed by β2.

The amount of movement of the optical axis is expressed as R(βxy+), and the value of R changes depending on the zoom magnification when copying the image area. The registration roller construction ON timing is a(α1-xl
)+Z. a is the number of clocks p per unit length of αl, and 2 is the number of clocks to turn on the registration roller during normal copying.

When multiple color development units exist, the 0N10FF timing of the development drive clutch is changed depending on which unit is selected, and the unit corresponding to the input color is selected. The storage tray paper feed clutch is driven at a timing such that when an even-numbered image area is copied, it feeds the transfer paper stored in the tray.

620 to 622 are resistors and photointeracitors that detect the notches of a round bread having radial notches that rotate in synchronization with the photoreceptor drum and generate clock pulses.

The timing of the copier is controlled by this number of pulses.

FIG. 19 shows the original table 20 and the X-axis scale 20a.

It shows the y-axis scale 20b.

It is also possible to specify the area by using a combination of the left, right, up, and down shift keys in the area operation section in FIG. 7 and the 10 key 34 in the operation section in FIG. 4 in accordance with the area specification number on the document scale 20. First, press the edit start key on the area operation section shown in FIG. 7, and then press the 693 key or 694 key to specify the position on the X axis. The left and right shift keys move left and right on the X axis, and it does not matter which one is pressed when setting the initial address.

After pressing the left or right shift key, the position of the desired area on the X-axis is determined using the 10 key 34 of the operating section in FIG. Next, the y-axis position is determined by a combination of the upper and lower shift keys and the io key 34 to determine the position on the y-axis. The editing work in which the editing area can be specified by performing the operations of the shift key and the 10 key 34 four times to determine the coordinates is completed by pressing the editing end key of the area operation unit shown in FIG.

In the case of the area designation number and position indicator on the original scale, first press the edit start key in the area operation section shown in FIG. 7, then press the left, right, top, and bottom shift keys to determine the positions of the X and y axes. Move the X-axis position by pressing the left shift key continuously or by pressing ON or OFF. While the shift key is being pressed, the position indicators (LEDs) 20c and 20d shown in FIG. 20 are shifted and displayed in accordance with the depression. Next, by pressing the upper and lower shift keys to specify the y-axis position, the movement changes from the X-axis position to the y-axis position. Operate the left, right, up, and down shift keys to determine this coordinate, and! ,
Determine the coordinates (addresses) of the four points on the seven axes.

To finish the editing work, press the edit end key.When the edit end key is pressed, the display form of the position display will be as shown in Figure 21? The Indian display switches to the X-axis and y-axis area display.

Effects The present invention is as described above, and according to the present invention, it is possible to provide a relatively simple device and a copying machine that enables image editing at low cost.
