Abstract

PURPOSE:To improve the function of picture editing and the operability of a picture editing area input part by setting optionally the number of picture areas on the same original surface. CONSTITUTION:An editing start key on an operation part indicates the start of editing of an original, and position information of a pressure-sensitive sheet 67 is cancelled unless this key is depressed. An editing end key indicates the end of editing of the original, and designation of areas is terminated when this key is depressed, but plural areas in the original can be designated optionally if this key is not depressed. A preference key is depressed for the original whose area is preferentially secured if overlapping of areas occurs when areas of many originals are designated. Picture area data of every original inputted from an area operating part 612 is stored in a specific address of a ROM604, and the number of picture areas of one original is not limited to 2. At the normal copying time, erase data is stored in a specific address of a ROM603 for every size.

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).

Conventional technology Extracting the necessary parts of multiple manuscripts in an analog manner to create one 7
Various copying machines are known which are equipped with so-called analog image editing functions for editing or compositing images on a 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 the second document with the gap and copies it as one document. A method in which the copied sheet is temporarily stored in a sheet storage section inside the machine, and when copying the second original, this sheet is sent again to the transfer position t, and the necessary part of the second original is copied on the same surface as the copying surface of the first original, etc. It has been known.

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 conventional composite copying apparatuses has been publicly 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 a 1iIiii image area, many switches were required and the device became 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, the first ffi document set at a predetermined position by the document exchanger 1 is illuminated by a well-known illumination and exposure optical device 8 including a light source 2, mirrors 3 to 6, and a lens 7. 9 is imaged and exposed.

The surface of the photoreceptor 9 is uniformly charged by the charger 1O and exposed to light by the illumination exposure optical device B8 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 11.

The developed image on the photoreceptor 9 is transferred at a transfer position to a transfer paper sheet 4 serving as copy paper fed from paper feed sections 12 and 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 photoreceptor 9 is neutralized and cleaned by the cleaning device 16, and the process from charging is repeated again.

The transfer paper 14 on which the image of the i1 original has been transferred is sent to the storage device. In FIG. 1, the transfer dome 15 also serves as a storage device. For this purpose, the transfer paper 14 fed from the paper feed section 12, 13 is first shifted by a clamp 17 provided on the transfer drum 15. 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 90 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 5 where there is no transfer paper and making the recess face the photoreceptor 9. There are many methods available such as how 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 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 drum 15. By rotating the image 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 document. In this way, when images of a predetermined number of originals starting from the third original are transferred and combined onto the same side of one transfer paper,
4 is unclamped, fixed by the fixing device 18, and discharged to the paper discharge tray 19.

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 may be used, which has a feed belt 21 and feeds and sets the manually inserted document to a predetermined position. can.

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 original, it is necessary to adjust the deviation between the combining position of the first original and the information position of the second original in one direction of transfer paper feeding by adjusting the timing of feeding of the transfer paper. The photoreceptor 9 is rotated with a desired timing shift relative to the rotation of the photoreceptor 9. At this time, in order to avoid a gap between the photoreceptor 9 and the transfer drum 5, the transfer drum 15 is placed 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 fed from the paper feed sections 12 and 13 to the transfer position by the photoreceptor 9). After the transfer paper is transferred by a known means, the transfer paper is fixed by the fixing device f[118], and then the first gate 28 is connected to the path to the paper discharge tray 19.
It is sent to a storage tray 30 through a storage path 29 which is switchably provided. 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 copy sheets of the first JMC manuscript are stored in the storage tray 30, the second manuscript is copied. In the figure, related parts such as the document exchange device 1, the illumination exposure device 8, and the photoreceptor 9 are the same as in FIG. 1, and therefore their explanation will be omitted.

When copying the second original, the paper is fed from the storage tray 30 in advance according to the exposure timing or by the paper feed roller in the storage tray 30, and is stopped by the registration roller provided in the middle of the transfer paper conveying means 27. The rotation of the registration rollers is adjusted in accordance with 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 is aligned with the photoreceptor. Adjustment is made so that when the transfer position 6 is reached, the image of the information of the second document formed on the photoreceptor 9 is exactly at the transfer position. 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.

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 gate 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 paper into the storage tray with the copied surface facing up and the leading end becoming the rear end. When the second dart is sent to the storage tray 30 through the switching path 32 by switching the second dart, 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.

To make composite copying, double-sided copying, and even double-sided composite copying possible by providing two (2) 28 and 31 and making it possible to switch the method of feeding the transfer to the storage tray between the two. I can do it.

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

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, push key 36, print key 31, density adjustment key 38, standard mode setting key 39, paper feed selection key 40,
Magnification setting key 41, double-sided copy key 42 for double-sided originals and single-sided originals, stack key 43, sort key 44, right blank key 45, right blank key 46, reverse paper ejection key 4
7. When the composite copy key 48 is turned on, it is not normally visible on the display section 49i50, but when it is turned on, a display as shown in the figure appears.

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 an operation, press and hold the left blank key 45.
When 15 is input using the 10 key 34, the 7-segment display at the top of the display section 47 lights up as @151. This may be blinking, and when you release the left blank key 45, 115# disappears and 1
Return to 1n. 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 simply flip over the many ejected transfer sheets and the pages will be aligned in order 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 and 13, and the display section 49 shows that the first paper feed tray is A4,
B4 and A3 paper sheets are set in the second and third paper feed trays, respectively, and when the first paper tray is selected, the A4 display area is surrounded by a frame.

If you want to select the second row, press the paper feed selection key 4°, the frame will move to the second row, and the second row will be selected.

In order to set the magnification, the enlargement key and the reduction key (magnification setting key 41) are pressed sb, and when they are pressed, one display is displayed on the display section 49 in steps of, for example, one tick. And for example 1
When 71%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.When pressed, the copying is interrupted, and when pressed again after performing the emergency copy, the interrupt key 35 is used.
You can return to the previous mode and restart Sycopy.

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

The standard mode setting key 39 is used to change to a preset mode when pressed, for example, A4.
If you set a magnification of 100% (actual size) in the size, the mode used by the previous person will be 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% 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 the figure shows an example in which the left blank, right blank keys 45 and 46, composite copy key 48, and 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 4903 is displayed when there is transfer paper in the printer bin.
It 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 to remind the user that he/she has forgotten the manuscript.

Display 4905 lights up when interrupt key 35 is pressed.

Display 5001 lights up during warm-up.

A display 5002 lights up when warm-up is completed and copying is started when the print key 37 is pressed.

Display 5003 is displayed numerically when there is an abnormality in the machine, and at this time display 5004 also lights up and a serviceman is called. This number allows you to identify abnormalities.
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. When the door on the sorter side is open, the display will be 5005°5006.

Displays 5008 and 5009 light up when there is a jam.
In case of jam in the sorter, display 5009゜5006
lights up.

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

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

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

In the operation panel shown in FIG. 2B, 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 detects the size of the original and adjusts the size of the copied transfer paper in a mode in which 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 the 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 II (a), there is a document jam display 57, a set confirmation display 58 that lights up when the document is incompletely set, and a set confirmation display that lights up when the document is set in 5ADF mode. Original insertion display 59 that lights up;
There is 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. Figure 6 (a) - CR to @
T screen contents are shown.

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 the figure), 64 is a part of the first original, and 65 is a part of the second original. 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), 64&, 64b are portions of the first (same document) 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 the 93-inch reduction mode to the part shown in the figure. A portion 66 of the third document is then copied in 115% enlargement mode.

In FIG. 6, 64 is a portion of the first original. 65 is a portion of the second manuscript.

66 is a portion of the third manuscript. 66 partially overlaps, but 65 is copied with priority. Reference numeral 64 indicates the position of the copy at the same size, 65 at a reduction of 93 inches, and 66 at a reduction of 87 inches.

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

Although 64b and 65 partially overlap in the same way as in Figure (e), 65 is copied preferentially. In Figure @, 64a and 164b are part of the first original. 65 is a portion of the second manuscript. 64b and 65 partially overlap, but 64a
, 64b (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(a). If the CRT is a color type, for example,
), 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 priority order is red, yellow, blue, etc., or a solid line from the highest priority order.

It is also possible to predetermine a dashed line, a dashed line, etc.

The numbers in 64, 65, and 66 shown in FIG. 6A indicate the order of the originals. On a color CRT, the first document is red,
If it is predetermined that the second original dose is blue and the third original 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 document, has signal lines for inputting and outputting each matrix signal on the x, l, and ly axes. You can also enter location information.

The I10 controller 68 is connected to a host μepu, which will be described later, via a data bus.

The document 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 is composed of multiple keys (left, right, up, down), zoom keys (up, down), and 9 color designation keys (black, red, blue).

Determination of whether a key has been pressed is based on a matrix signal of a scan signal for key code detection and a return signal which returns the scan signal to the I10 controller 68 when a key is pressed.

The keys of the operation section will be explained as follows: (1) The editing start key is a key that notifies the start of editing 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 informs the end of editing for the draft. 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.

■Priority key Press this key when specifying the area for multiple originals and if there is overlap in the area, you want to give priority to securing the area for the original.

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.

With the 691 and 692 keys, the data of the X-axis position in the RAM is updated.

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

■ The zoom key is a key pressed when changing the size of the image within the area frame, and can be used to steplessly instruct the sb enlargement or reduction direction.

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

■ The pressure-sensitive sheet key determines the position information of the editing area frame, and is valid while the Collect End key is pressed after the 6 jlJ Iil collection sme start key, and is used for the matrix signal of the 6jlJX-axis y-axis scan signal and scan return signal. The quality is constant.

FIG. 9 is a diagram showing the pressure sensitive sheet showing the X-axis and the y-axis, and FIG. The area surrounded by four corners inside the transfer paper is an image editing area.

FIGS. 11(IL) and (b) are diagrams showing the area shift state, and FIG. 12 is the RAM map at that time.

In FIG. 7, To, 71 is a driver, and 72 is a comparator.

Next, the optical illumination section will be explained.

One element for image editing is conversion of 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.

Also, the first mirror 3 (velocity 17) integrated with the light source 2
By scanning the second mirror 4 relative to the document,
The image of the original is continuously projected onto the photoreceptor 9.

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

1) The magnification conversion in the mirror scanning direction is determined by the relative relationship between the surface speed vo of the photoreceptor 9 and the first mirror scanning speed y. If the magnification is m, then m-11τ (This does not apply to full exposure copiers such as fludge and exposure) 11) The magnification conversion in the direction perpendicular to 1) above (the axial direction of the photoreceptor drum) is so-called zooming. done by.

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 correct the total path by Δt. If the focal length of the lens is f, then Δa-(--1)f Δt=(m-1--2) f When a zoom lens is used, total bus correction can be omitted.

Image position transformation is achieved by the following means.

1) 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 10 with the photoconductor when transferring the developed toner image formed on the photoconductor. Ru. (The timing relationship between the photoreceptor and the transfer paper may be kept constant, and the mirror scanning start timing may be changed.) l) Image position conversion in the direction perpendicular to l) above is 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 certain information is to be illuminated in a partial area alc of the document area A, the image is normally formed on a partial area a of the area B of the photoreceptor. Compatible with Photoconductor copy paper or transfer paper. Now, from the partial area of lens 7, lens 4
It moves to a partial area b' that has moved by a distance t in the direction of movement. In other words, 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. can.

If used in conjunction with magnification conversion by moving the lens 7 off 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 as K by calculating the deviation between the information position and the specified copying position using the control device, and controlling the lens moving device using the calculated signal.

An enlarged example of the structure for moving the lens is shown in Figure 914 and Figure 1.
As shown in FIG. 5, a lens stand 73 to which a lens 7 is fixed is supported by a lens bracket 74, and a lens bracket 4 is screwed onto a screw shaft 76 rotatably supported by an optical system frame 75. A structure may be used in which the lens 7 is moved in a direction perpendicular to the optical axis by reversibly rotating the shaft 76 directly by the motor 77 or by the motor 77 via a belt or the like. 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.

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 method of controlling the copy paper feed timing and lens movement described above, it is also possible to change the setting position of the original by making the original movable together with the original placing glass in one direction or in two orthogonal directions. Adjustment methods are also available.

1) Represented by 10Z. a is the number of clocks per unit length of α, and 2 is the number of clocks to turn on the registration roller during normal copying.

When there are development units of multiple colors, 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 it feeds the transfer paper stored in the tray when an image area of an even number of rollers is to be copied.

Reference numerals 620 to 622 are resistors and photo-in cracks that detect the notches of a circular pan 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 The present invention is consistent with the above-mentioned principles, and has the effect that the number of image areas on the same document surface can be arbitrarily set.
