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 and copies them as one document, or copies the first document. The seat was then stored in the seat storage area inside the aircraft and placed in the 2nd W.

A known method is to refeed this sheet to a transfer position when copying a document, and copy a necessary portion of a second document on the same surface as the copy surface of the first document.

In the latter copying machine, an exposure relative position adjustment means and an erase means are used to align each document.

As described above, although the concept of image editing in a composite copying apparatus is known, there has been no concrete disclosure of techniques for improving operability or various functions related to image editing.

Furthermore, in the past, when trying to set an image area, a large number of switches were required and the device was expensive.

OBJECTS The present invention was made against the background of such conventional examples, and an object of the present invention is to improve the image editing function and the operability of the image editing area 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, a first document set at a predetermined position by a document changing device 1 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 an image is formed on a photoreceptor 9. exposed to light.

The surface of the photoreceptor 9, which is uniformly charged by the charger 10, is an illumination exposure optical device! i8 is exposed to light 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 a developing device 1ill.

The developed image on the photoreceptor 9 is transferred at a transfer position to a transfer paper 14 serving as a copy paper fed from a paper feed section 12.13.

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 window light body 9 is neutralized and freed by the 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. For this purpose, the transfer paper 14 fed from the paper feed section 12, 13 is first provided on the transfer drum 15 or 2-fumped by the 2-dump 17. The transfer paper 14 is the transfer drum 1
After the image of the first document is transferred from the photoreceptor 9 through one rotation by being clamped by the photoreceptor 9, the transfer drum 15 is temporarily stored while being fixed to the transfer drum 15 at a position where it does not contact the photoreceptor 9.

There is a method of changing the distance between the transfer drum 15 and the photoreceptor 9 in order to keep it in a non-contact state with the photoreceptor 9 during storage, and a method of providing a recess in the part of the transfer drum 15 where there is no transfer paper and placing the recess in the photoreceptor 9. A variety of methods can be used, including a method of facing each other.

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 1
At , the first original is taken out and the second 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 image of the second document formed on the photoconductor 9 is transferred to a transfer paper fed from a storage device, such as a transfer paper. By rotating the drum 15 again, the image is transferred onto the transfer paper 14, which is sent to the transfer position, on the same surface as the image of the first original. In this way, when images of a predetermined number of documents starting from the third document are combined in one copy on the same side of one transfer sheet, the transfer sheet 14 is unclamped, fixed by the fixing device 18, and placed on the output tray. It is discharged on 19th.

The document exchange device 1 is simply the document device glass 20 of a copying machine.
Alternatively, a semi-automatic document handling device or a fully automatic document handling device that has a feed belt 21 and feeds and sets manually inserted documents to a predetermined position can be used. .

In FIGS. 1 and 2, the transfer drum 15 is also used as a storage device for transfer paper after the image of the first original is transferred until the image of the second original is transferred. Therefore, when transferring the image of the second document, if the deviation in the transfer paper feeding direction between the combination position of the first document and the information position of the second document is adjusted by the transfer paper feeding timing, the rotation of the photoreceptor 9 may be adjusted. On the other hand, the photoreceptor 9 is rotated with a desired timing shift. At this time, in order to avoid gaps between the photoreceptor 9 and the transfer drum 15, the portion of the transfer drum 15 facing the photoreceptor is formed as a recess at the stop position of the transfer drum 15 to avoid direct contact; A structure may be adopted in which the transfer drum 15 moves away from the photoreceptor 9 when stopped.

The storage device can be provided separately instead of being shared by the transfer drum 15. For example, as shown in FIG. 2, the transfer paper is sent from the paper feed units 12 and 13 to the transfer position by the photoreceptor 9 by a transfer paper conveyance means 27 having a feed roller 22 and a guide 23°24.25 or a feed belt 26, After being transferred by known means, the transfer paper is fixed by a fixing device 18 and then sent to a storage tray 30 through a storage path 29 which is switchably provided by a first gate 28 with respect to the path to a paper discharge tray 19. When feeding the paper into the storage tray 30, it is always reversed 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 sheet or a predetermined number of transfer sheets on which the first original is copied is stored in the storage tray 30, a 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, use the paper feed roller in the storage tray 30 or the registration roller that is fed out of the storage tray 30 in advance in accordance with the exposure timing and stopped by the registration roller provided in the middle of the transfer paper conveying means 27. The rotational drive is performed with timing adjustment according to the positional deviation calculated by the composite position signal and the information position signal, and the composite position of the transfer paper carrying the image of the first document reaches the transfer position of the photoreceptor 9. Adjustment is made so that the information image of the second document formed on the photoreceptor 9 is exactly at the transfer position. The transfer sheets are stored in the storage tray 30 in a number corresponding to the number of originals to be combined, and are returned to the transfer position of the photoreceptor 9 through a circulation cycle.

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 dart 28.

In FIG. 2, another second gate 31 is provided from the fixing device 18 to the first r-t 28, and the state is reversed from the case where the transfer paper is sent to the storage tray 30 through the first gate 28. , that is, without reversing after passing through the fixing device,
In the figure, a switching path 32 can be provided to feed the ducks into the storage tray with the copied side facing 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 is possible.

By providing two darts 28 and 31 and making it possible to switch the method of feeding the transfer to the storage tray, composite copying, double-sided copying, and even composite copying of both images are possible. I can do it.

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

In FIG. 3, 33 is a sorter, and in FIG. 2, it can be connected to a copying machine in place of the paper discharge tray 19.

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, for double-sided originals, single-sided Double-sided copy key 42 for originals

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.
If you want to make 11m, press and hold the left blank key 45 and input 15 using the 10 key 34, and the 7 segment display at the top of the display 49 will light up as "15".This may be blinking, and the left blank key When you release 45, ``15#'' disappears and returns to 111. 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 will have one sheet on the bottom side. Since it is a double copy, if you turn it upside down, you can print the many ejected transfer sheets as they are, and then comb them back to align the pages in order from the first sheet.

The stack key 43 and the note key 44Fi need no explanation and are well known.

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 and 13, and the display section 49 shows that the first paper feed tray is A4,
The second and third paper feed trays each have B4. When A3 is set and 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, press the enlarge key and reduce key (magnification setting key 41), for example 1%.
One image is displayed on the display section 49 in increments. And for example @
When '71%' is displayed, 'A3→A4' is also displayed to notify that A3 will be reduced to A4 at a magnification.

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 IO 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 - with the IO 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 Rucoby, and pressing it again after performing the emergency copy will cause
You can return to the previous mode and restart Sicobee.

Clear/stop key 36, density fiL! Maintenance key 38
, print key 37 will not be described.

The standard mode setting key 39 is used to change to a preset mode by pressing it.
If you set the magnification to 100% (actual size) for A size,
If the person in front of you is using the print mode, which is A3 size, has a reduction rate of 71 inches, and is in double-sided copy mode, you can simply press the standard mode setting key 39 to save yourself the trouble of canceling these settings. The magnification can be changed to 100-.

The above is the explanation of the key, and in the case of the figure, it is blank on the left.

This shows an example in which the right blank keys 45 and 46, the composite copy key 48, and the reverse paper ejection key 47 are covered because they are not keys that are always used.

Next, display functions that have not yet been explained regarding the display sections 49 and 50 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 4902 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 5010 lights up when the key counter is not set.

Display 5011111,) Lights up when the fuel is insufficient.

The operation section of the ADF is shown in FIG. 5 and will be briefly explained.

On the operation panel shown in Figure (B), the ADF key 51 is used to automatically feed a document, and the ADF key 51 is used to manually insert a document from 52 companies, 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 (6jl), and the size of the copied transfer paper is set. It is used when you want to unify the

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 the 7-segment LED 5.
6.

On the display panel shown in the same figure (JL), there is a document jam display 5.
7. Set confirmation display that lights up when the original is incompletely set. 8. Original insertion display 59 that lights up when copying starts if the original is set in ADF mode. , and a document insertion display 60 that turns off when the document is inserted.

Next, the display unit according to the present invention will be explained. The display is C
I'm using RT. The CRT screen contents are shown in FIGS. 6(a) to (ω).

In Figure (a), 61 indicates the size of the transfer paper, and scales 62 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. Character displays below the scales 62 and 63 indicate the mode content and transfer paper size of each part of the original.

In figure (b), 64 is a copy of the first manuscript, 65
is a portion of the second manuscript. The first original 65 is copied at the same size as indicated by the text. The second original 65 is copied at a reduction of 93- as indicated by the text.

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

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

In Figure (e), 64 is a portion of the first original. 65 is a portion of the second manuscript.

66 is a portion of the third manuscript. Although 65 and 66 partially overlap, this indicates that 65 is copied with priority. 64 represents the position occupied by the copy at the same size, 65 at 93% reduction, and 66 at 87% reduction.

In figure (f), 64&, 64b are parts of the first original. 65 is a portion of the second manuscript.

Although 64b and 65 partially overlap as shown in Figure (el), 65 is copied preferentially.

In the figure (b), 64a and 64b are parts of the first original. 65 is a portion of the second manuscript.

64b and 65 partially overlap, but 64a and 6
This is a case where it is necessary to copy both depending on the content to be copied to 4b (this is a case where no priority order is given).

In the above, examples on a CRT screen have been shown in FIGS. 6(a) to 6(0). If the CRT is a color type, for example, figure (a)
), displaying 64 in green, 65 in yellow, and 66 in red will make it easier to see. If the CRT is not a color type, the CRT can be distinguished by a solid line at 64, a broken line at 65, and a dashed-dotted line at 66.

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 predetermine a dashed line, a dashed line, etc.

The numbers 64, 65, and 66 shown in Figure (a) indicate the order of the originals. For a color CRT, if you predetermine that the first document is red, the second document is yellow, and the third document is blue, the numbers in 64, 65, and 66 are not 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 original, has signal lines on the X and Y axes for inputting and outputting each matrix signal. You can now enter location information.

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 is pressed, the scan signal for detecting the key code and the scan signal when the key is pressed are sent to the VO controller 6.
According to the matrix signal of the return signal which returns to 8.

The keys of the operation section will be explained as follows: (1) Edit-Start key is a key that notifies the start of editing the document.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 indicates the end of editing the manuscript. When this key is pressed, all area specification ends. If the editing end key is not pressed, multiple areas within the document can be arbitrarily specified.

■ The priority key is pressed when specifying an area for a multi-sheet document and if there is a large overlap in the area, the priority key should be given to the document for which the area should be secured.

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.

, 691, and 692 keys update the X-axis position data in the RAM.

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

■ The zoom key is a key you press to change the size of the image within the area frame, and you can steplessly instruct the image in the direction of recess, enlargement, or reduction.

■ The color specification 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 after the reed editing start key is pressed, and is determined by the matrix signal of the hb, x1my axis scan signal and scan return signal.

The entire area of TxnTyn is scanned using the scan timing TX, the return signal Ty, the boat signal xly, and the position information to determine the position.

FIG. 7 is a diagram showing the pressure sensitive sheet showing the X-axis and the y-axis, and FIG. 10 is a diagram showing the state in which the transfer paper is placed on the pressure-sensitive sheet 67. The area surrounded by four corners inside the transfer paper is an image editing area. Figures 11(a) and Cb) show the area shift state, and Figure 12 shows the RAM at that time.
It is a map. In FIG. 7, 70 and 71 are drivers, and 72 is a comparator.

Next, the optical illumination section will be explained.

One of the elements for image editing is conversion of the image 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 an 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. Ru.

Further, the image of the original is continuously projected onto the photoreceptor 9 by scanning the first mirror 3 (velocity τ) and the second mirror 4, which are integrated with the light source 2, relative to the original.

To convert the size of the image, variable-magnification projection is performed.

1) The magnification conversion in the mirror scanning direction is the surface speed τ of the photoreceptor 9. It is determined by the relative relationship between and the first mirror scanning speed. If the magnification is m, then Q - - τ (fludge:, this does not apply to full exposure copying machines such as exposure) il) The magnification conversion in the direction perpendicular to 1) above (the axial direction of the photoreceptor drum) is called zooming. Let's do it.

In the example shown in FIG. 1, a fixed fish collection lens is used. Move the lens 7 in the optical path direction by an amount (Δa) that matches the magnification m, and move the mirror 5,
6 and corrects the total bus by Δt. If the focal length of the lens is f, then Δa-(--1)f ΔL = (m+--2)f When a zoom lens is used, the daughter and /l/lotus corrections can be omitted.

Image position transformation is achieved by the following means.

l) Position conversion 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 IO with the photoconductor when transferring the developed toner image formed on the photoconductor. (It is also possible to keep the timing relationship between the photoconductor and the transfer paper constant and change the mirror scanning start timing.)I+) Image position conversion in the direction perpendicular to 1) above involves image projection by moving the lens in the direction perpendicular to the optical path. Achieved by position transformation. FIG. 13 is a plan view of the lens optical path.

In FIG. 13, when exposing information in partial range a of document range A, the image is normally formed on partial range A of range B of the photoreceptor. The photoreceptor corresponds to copy paper or transfer paper. The lens 7 is now moved from the partial area b' to a partial area b' moved by a distance in the direction in which the lens 4 has 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 and 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 over the optical axis, variable magnification copying and composite copying can be performed simultaneously. 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 that is rotatably supported by an optical system frame 75, and the screw shaft 76 is reversibly rotated by a motor 77 directly or via a belt or the like, so that the lens 7 can be illuminated. Structures that move in a direction perpendicular to the axis can be utilized. If the movement of the lens bracket 74 is guided by a guide bar 78 fixed to the optical system frame 75, the lens can be smoothly reciprocated without tilting.

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, and is movable in the optical axis direction, thereby making it possible to change the magnification.

To convert the image position, in addition to the above-mentioned method of controlling the copy paper feeding timing and controlling the movement of the lens, it is also possible to set the original by making the original movable together with the original placing glass in one direction or in two directions orthogonal to the original. A method of adjusting the position is also available.

Next, the control section will be described.

The entire copying machine is controlled by a control program stored in ROM 603. The control program is roughly divided into two parts: one is a program (standby routine) that processes image editing input, copy mode input, etc., and the other is a timing control program (copy routine) for copying process load.

Image editing inputs processed in the standby routine include image area input from the area operation section and area layout input from the keyboard.

Examples of loads include the erase unit shown in Figure 16, optical axis moving motor, development drive clutch, registration roller clutch, and storage tray paper feeder. Ru.

The operation of erase data will be explained based on FIGS. 18(a) to (C).

FIG. 6A shows how the image area data for each document inputted through the area operation unit 612 is stored at a specific address in the RAM 604. The number of image areas for one document is not limited to two. Figure (b) shows how normal copy/temporary erase data is stored at specific addresses in the ROM 603 for each size. Here, Xl and X2 are the clock numbers indicating blinking timing of the erase unit, and Y, Y2 indicate each half of the selection data of the light emitting elements in the erase unit.

a is the number of strokes corresponding to the unit length of α, and 2 is the number of strokes when the registration roller clutch is turned ON at the time of 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 w unit corresponding to the input color is selected.

The storage tray paper feed clutch line is driven at a timing such that when an even-numbered image area is copied, the transfer paper stored in the tray is fed.

Reference numerals 620 to 622 denote resistors and 7 automatic interrupters which detect the notches of a circular bread having radial notches that rotate in synchronization with the photosensitive drum and generate clock pulses. The timing of the copier is controlled by this number of pulses.

Effects of the Present Inventor As described above, the present invention has the following features: (1) A desired area of a document can be designated and multiple areas can be displayed using a display device; (2) A display device can be configured using an image area input device. (3) Since the m-collection is checked on the display device and copied after completion, there is no need to copy the system by the editing system.
