Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image editing and copying machine that extracts necessary portions of a plurality of originals and edits them on one sheet (transfer sheet).

2. Description of the Related Art Various copying machines having a so-called image editing function for extracting necessary portions of a plurality of originals and editing or combining them on one sheet (transfer paper) have been known.

Conventionally, in this type of copying machine, a first original in which a portion into which a second original should be inserted is perforated and the second original is superposed and copied as one original, or the first original is copied.
The copied sheet of the original is temporarily stored in the sheet storage unit in the machine, and when the second original is copied, the sheet is retransmitted to the transfer position, and the necessary portion of the second original is copied on the same surface as the first original. Things are known.

In the latter copying machine, the exposure relative position adjusting means and the erasing means are used to align the respective originals.

As described above, the concept of image editing in the composite copying apparatus has been publicly known, but there has been no specific disclosure of a technique for improving operability or various functions related to image editing.

Further, conventionally, there has been a drawback in that when an image area is set, a large number of switches are required and the cost becomes expensive.

OBJECT The present invention has been made on the basis of such a background of the conventional example, and an object thereof is to improve the function of image editing and improve the operability of the image editing area input section.

Configuration The configuration of the present invention will be described below with reference to the drawings. First of all
The function of the copying machine, which is the premise of the present invention, will be described with reference to FIGS. 2, 2 and 3, and then the present invention will be described with reference to FIGS.

In FIG. 1, the first document set at a predetermined position by the document replacement device 1 is illuminated by a 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 photoconductor 9. Exposed. The surface of the photoconductor 9 uniformly charged by the charger 10 is exposed by the illumination / exposure optical device 8 to form an electrostatic latent image. The electrostatic latent image is developed and visualized by the developing device 11 while the photosensitive member 9, for example, the photosensitive drum is moving.

The visible image on the photoconductor 9 is transferred at a transfer position to a transfer paper 14 serving as a copy paper supplied by the paper supply units 12 and 13. A transfer drum 15 is used in FIG. 1 as a means for conveying the transfer paper 14 to the transfer position.

After the transfer, the photoconductor 9 is destaticized, cleaned by the cleaning device 16, and the process from charging is repeated.

The transfer paper 14 onto which the image of the first original is transferred is sent to the storage device. In FIG. 1, the transfer drum 15 is also used as a storage device. Therefore, the transfer paper 14 supplied from the paper supply units 12 and 13 is first clamped by the clamp 17 provided on the transfer drum 15. The transfer paper 14 is clamped by the transfer drum 15 to rotate once to transfer the image of the first original from the photoconductor 9, and then temporarily fixed to the transfer drum 15 at a position where it does not contact the photoconductor 9. Be stored.

A method of changing the distance between the transfer drum 15 and the photoconductor 9 so as to keep the photoconductor 9 in a non-contact state during storage, and a transfer drum.
Various methods such as a method in which a concave portion is provided in a portion of the transfer paper 15 where there is no transfer paper and the concave portion faces the photoconductor 9 can be used.

In the above process, the image of the first original is transferred to the transfer paper, and the original replacement device 1 is provided while the transfer paper is stored by the storage device.
At, the first original is taken out and the second original is set at a predetermined position. After that, the photosensitive member 9 is charged and exposed and developed in the same process as in the case of the first original, and the image of the second original formed on the photosensitive member 9 is transferred onto the transfer paper, for example, the transfer drum 15 supplied by the storage device. When it is rotated again, it is transferred onto the transfer paper 14 sent to the transfer position on the same surface as the image of the first original. In this way, when the images of a predetermined number of originals from the third original onward are transferred and synthesized on the same surface of one transfer paper, the transfer paper 14 is released from the clamp, is fixed by the fixing device 18, and is discharged to the discharge tray 19. Is discharged to.

The document replacement device 1 may be configured to be manually replaced on the document mounting glass 20 of copy paper, and has a feed belt 21 so that a document inserted by hand is fed and set at a predetermined position. A semi-automatic document handling device or a fully automatic document handling device can also be used.

The transfer drum 15 is also used in FIGS. 1 and 2 as a storage device for the transfer paper between the transfer of the image of the first original and the transfer of the image of the second original. Therefore, when the image of the second original is transferred, when the deviation between the composite position of the first original and the information position of the second original in the transfer paper feed direction is adjusted by the transfer paper feed timing, the rotation of the photoconductor 9 The photoconductor 9 is rotated with a desired timing deviation. At this time, in order to avoid slippage between the photoconductor 9 and the transfer drum 15, the portion of the transfer drum 15 facing the photoconductor is formed as a recess at the stop position of the transfer drum 15 to avoid direct contact, or to stop the transfer. Sometimes, the transfer drum 15 may be structured so as to move away from the photoconductor 9.

The storage device may be provided separately instead of being shared by the transfer drum 15. For example, as shown in FIG.
The transfer paper is fed from 12, 13 to the transfer position by the photoconductor 9 by the transfer roller transporting means 27 having the feed roller 22 and the guides 23, 24, 25 or the feed belt 26, and after transfer by the known means,
After the transfer paper is fixed by the fixing device 18, the transfer paper is sent to the storage tray 30 through the storage path 29 which is switchably provided by the first gate 28 to the path to the paper discharge tray 19. When it is sent to the storage tray 30, the tip is always inverted so that it is sent as the tip, and in the example shown in the figure, the copy surface is faced down and stored.

After one 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, the relevant parts of the document replacement device 1, the illumination exposure device 8 and the photoconductor 9 are the same as those in FIG.

When copying the second original, the registration roller in the case of being stopped by a sheet feeding roller in the storage tray 30 or a registration roller provided in the middle of the transfer sheet conveying means 27 previously sent out from the storage tray 30 at the exposure timing. The rotational drive is performed under 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 original reaches the transfer position of the photoconductor 6. Then, the adjustment is performed so that the image of the information of the second original formed on the photoconductor 9 is exactly at the transfer position. Transfer paper is stored in the number of storage trays according to the originals to be combined.
It is stored in 30 and sent again to the transfer position of the photoconductor 9 to repeat the cyclic feeding.

When the composite copying of the final document is completed, the transfer sheet is discharged to the 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 so that the transfer paper is reversed to the case where the transfer paper is sent to the storage tray 30 through the first gate 28.
That is, it is possible to provide the switching path 32 that feeds to the storage tray in a state in which the front end is the rear end with the copied surface in the figure without being inverted after passing through the fixing device.
When the transfer paper is sent to the storage tray 30 through the switching path 32 by the switching of the second gate, the surface opposite to the previous one is brought into contact with the photoconductor and transferred to the transfer paper in the next copying process. That is, double-sided copying becomes possible.

By providing two gates 28 and 31 and enabling the transfer method of transfer to the storage tray to be switched in two ways, it is possible to perform composite copying, double-sided copying, and even double-sided composite copying. That is, the composite copying operation of the previous term is performed on one side, and then the storage tray 30 is provided with the second gate.
Double-sided composite copying is possible by sending from 31 through the switching path 32 and then again performing the composite copying operation on the back side.

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

It is displayed in the upper 7 segments of the display unit 49. Bottom 7
The segment display is for displaying the number of copies.
Also, as mentioned above, left and right blank keys 4 for binding margin adjustment
It is also used when setting the binding margin width with these 10 keys 34 while pressing 5,46. Although there is an enlargement / reduction key in the figure, it is also possible to use this as one magnification key, and input a desired% with the 10 key 34 while pressing this magnification key.

The interrupt key 35 is used when an urgent copy is needed during copying.Pressing it interrupts copying, and pressing it again after making an emergency copy returns you to the previous mode and makes a copy. It can be restarted.

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

The standard mode setting key 39 is used to change to a preset mode by pressing it. For example, if you set a magnification of 100% (actual size) in A4 size, the mode used by the previous person will be If the reduction mode is 71% for A3 size and the sort mode is for double-sided copy, you can change the magnification to 100% for A4 size by simply pressing the standard mode setting key 39 in order to save the trouble of canceling them.

The above is the description of the keys, and in the case of the figure, the left blank, right blank keys 45, 46, the composite copy key 48, and the reverse paper ejection key 47 are not the keys that are always used, and therefore the lid is shown. .

Next, the display functions of the display units 49 and 50 which have not been described will be described.

The display 4901 is lit when the original and the transfer paper do not match, and is of course determined including the magnification.

Display 4902 is lit when there is no paper in the paper feed tray.

The display 4903 is lit when the back side is copied in the double-sided copy.

A display 4903 is lit when the stack or sort key is pressed when there is a transfer sheet in the sorter bin, and warns the user not to mix it with the previously copied transfer sheet.

A display 4904 is a display warning that the manuscript is forgotten.

The display 4905 lights up when the interrupt key 35 is pressed.

The display portion 5003 is displayed by a numeral when there is an abnormality in the machine, and at this time, the display 5004 is also turned on to make a serviceman call. This number makes it possible to identify the abnormal part and has the meaning of self-diagnosis. It can also be used to display the waiting time in minutes during the warm-up described above.

The display 5005 is lit when the door is open. When the sorter side door is open, the displays 5005, 5006, 5007 are lit.

The display portions 5008 and 5009 are lit when a jam occurs, and the indicators 5009 and 5006 are lit when a jam occurs in the sorter.

The display 5010 lights up when the key counter is not set.

The display 5011 lights up when the toner is insufficient.

The operation part of the ADE is shown in FIG. 5, and will be briefly described.

In the operation panel shown in FIG. 2B, the ADF key 51 is used for automatically feeding a document, and the SADF key 52 is used for inserting a document into the hand, both of which are well known.

The size unifying key 53 is a mode in which the original size is detected and the magnification is automatically set so that it matches the transfer paper size in the selected paper feed tray. It is used when you want to unify.

The automatic paper feed selection (APS) key 54 is 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 obtained.

The counter key 55 is used when it is desired to display the number of originals, and the 7-segment LED 56 displays the number of originals.

The display panel shown in FIG.
Set confirmation display that lights up when the original is not completely set
58, a document feed display 59 that lights up when a document is set to start copying in the SADF mode, and a document insertion display 60 that indicates the direction in which the document is inserted and turns off when the document is inserted.

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

The display uses a CRT.

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

In the 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 part of the first manuscript. 65 is a part of the second original. Further, 66 is a part of the third manuscript. The character display below the scales 62 and 63 shows the mode contents and the transfer paper size of each part of the document.

In FIG. 6B, 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% as shown by the character display.

In FIG. 6C, 64a and 64b are parts of the first (same original) original.

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

In FIG. 6E, 64 is a part of the first original. 65 is a part of the second manuscript. 66 is a part of the third manuscript. 65 and 66 show that 65 is preferentially copied although they partially overlap.
64 is the same size, 65 is the reduction of 93%, and 66 is the position shown by the copy.

In FIG. 6F, 64a and 64b are parts of the first original. 65 is a part of the second manuscript. As in the case of FIG. 6E, 64b and 65 have a partial overlap, but 65 is copied preferentially.

In FIG. 6G, 64a and 64b are parts of the first original. 65 is a part of the second manuscript. 64b and 65 partially overlap, but depending on the contents copied to 64a and 64b, both need to be copied (that is, no priority is given).

The examples on the CRT screen are shown in FIGS. 6 (a) to 6 (g). If the CRT is of a color type, for example, Fig. (A)
When 64 is displayed in green, 65 in yellow, and 66 in red, it is easier to see. If the CRT is not a color type, 64 can be distinguished by a solid line, 65 by a broken line, and 66 by a dash-dotted line.

When there is a priority as shown in the figures (e) and (f),
It is also possible to predetermine red, yellow, blue, etc., or a solid line, a broken line, a one-dot chain line, etc. in descending order of priority.

The numbers in 64, 65, 66 shown in FIG. For a color CRT, if you decide in advance that the first manuscript is red, the second manuscript is yellow, and the third manuscript is blue,
The numbers in 64,65,66 are unnecessary.

Next, the operation unit for image editing is shown in the block diagram of FIG. A pressure-sensitive sheet 67 that uses a pressure-sensitive sheet to detect the position of a document has signal lines for inputting and outputting each matrix signal on the x-axis and y-axis, depending on the scan signal from the I / O controller 68 in the block diagram. You can enter location information.

The I / O controller 68 is connected to a host μcpu described later via a data bus. The original editing area is detected by the matrix information of the scan timing signal and the scan return signal of the pressed pressure sensitive sheet 67.

The key group 69 connected to the area operation section includes an edit start key, an edit end key, a priority key, and an area shift key (left,
Right, up, down), zoom key (up, down), color designation key (black, red, blue).

The key press judgment is the scan signal for key code detection and the scan signal when the key is pressed.
Return signal to the Matrices signal.

Explaining the operation section keys, the edit start key is a key for notifying the start of editing of the document, and if this key is not pressed, the position information of the pressure sensitive sheet 67 is canceled.

The edit end key is a key for notifying the end of the editing of the document, and when the key is pressed, the designation of the area is completed. If the edit end key is not pressed, it is possible to arbitrarily specify a plurality of areas in the document.

The priority key is pressed when a document is desired to be secured by giving priority to the overlap of regions when the regions of a plurality of documents are designated. When this key is pressed before, after, or during the area designation, the priority flag is set in the RAM that stores the number of documents.

The area shift key shifts the left, right, up, and down positions without changing the length of the frame of the specified area.

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

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

For 693 and 694 keys, the data of the x-axis position of RAM is updated.

The zoom key is a key to be pressed when changing the size of the image in the area frame, and can be instructed in the enlargement / reduction direction steplessly.

The color designation key is a key to be pressed when multicoloring is performed on copy paper.

The pressure sensitive sheet key determines the position information of the edit area frame and is effective while the edit end key after the edit start key is pressed, and is determined by the matrix signal of the x-axis and y-axis scan signals and the scan return signal. Judgment. Scan timing Tx ₁ and return signal Ty ₁ port signal, x ₁
As the position information of y ₁ , all the areas of Txn and Tyn are scanned to 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 the transfer paper is placed on the pressure sensitive sheet 67. The area surrounded by the four corners inside the transfer paper is the image editing area. 11 (a) and 11 (b) are diagrams showing the area shift state, and FIG. 12 is a RAM map at that time. In FIG. 7, 70 and 71 are drivers and 72 is a comparator.

Next, the optical illumination unit will be described.

As one element for image editing, there are conversion of image size and image position on the copy screen. In the analog image editing / copying apparatus to which the present application belongs, this is achieved by an optical image projection apparatus (optical system).

In the copying apparatus shown in FIG. 1, the document placed on the document mounting glass 20 is illuminated by the light source 2, and the image of the document is projected in a slit shape on the photoconductor 9 by the mirror groups 3 to 6 and the lens 7. It

Further, the image of the original is continuously projected onto the photoconductor 9 by the first mirror 3 (speed υ) and the second mirror 4 which are integrated with the light source 2 relatively scanning the original.

Variable-magnification projection is used to convert the image size.

i) The magnification conversion in the mirror scanning direction is determined by the relative relationship between the surface speed υ ₀ of the photoconductor 9 and the first mirror scanning speed υ. If the magnification is m, (This is not the case in a full-exposure copying machine such as flash exposure.) Ii) Magnification conversion in the direction perpendicular to the above i) (axial direction of the photosensitive 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 (Δa) that matches the magnification m, and set the mirrors 5, 6
By displacing and correcting the total path by Δl. Let the focal length of the lens be When using a zoom lens, correction of the total path can be omitted.

The image position conversion is achieved by the following means.

i) The position conversion in the mirror scanning direction is achieved by changing the relative positional relationship between the image and the transfer sheet, that is, the contact timing of the transfer sheet 10 to the photosensitive body when transferring the toner visible image formed on the photosensitive body.

(Keep the timing relationship between the photoconductor and transfer paper constant,
The mirror scanning start timing may be changed. Ii) Image position conversion in the direction perpendicular to the above i) is achieved by image projection position conversion by moving the lens in the direction perpendicular to the optical path.

FIG. 13 is a plan view of the lens optical path. In FIG. 13, when the information in the partial range a of the original range A is exposed, the image is normally formed in the partial range b of the range B of the photoconductor. The photoconductor corresponds to copy paper or transfer paper. Now, when the lens 7 is moved by l / 2 in the direction orthogonal to the optical axis, the distance l is moved in the moving direction of the lens 4 from the partial region b on the photoconductor.
It moves to the partial region b'which has moved only. That is, by selecting the amount of movement of the lens in the direction orthogonal to the optical path, it is possible to arbitrarily select the image forming position on the photoconductor, in the first place, on the copy paper in the direction orthogonal to the movement direction of the copy paper.

If this is also used together with magnification conversion by moving the lens 7 along the optical axis, it is possible to perform variable magnification copying for changing copying magnification and composite copying at the same time. The amount of movement of the lens in the direction orthogonal to the optical axis is set by calculating the shift between the information position and the designated copy position by the control device and controlling the lens moving device by the signal.

As a structure for moving the lens, for example, as shown in FIGS. 14 and 15, a lens base 73 for fixing the lens 7 is supported by a lens bracket 74, and the lens bracket 74 is rotatably supported by the optical system frame 75. It is possible to use a structure in which the lens 7 is screwed to the screw shaft 76 and the lens 7 is moved in the direction orthogonal to the optical axis by reversibly rotating the screw shaft 76 directly by the motor 77 or by the motor 77 via a belt or the like. it can. By guiding the movement of the lens bracket 74 by a guide bar 78 fixed to the optical system frame 75, the lens bracket 74 can be smoothly reciprocated without tilting the lens. If the optical system frame 75 itself can be moved in the direction of the optical axis screwed on a screw rod or the like in the same manner as in FIGS. 14 and 15, the magnification can be changed.

In addition to the method of controlling the feed timing of the copy paper and the control of the lens movement for the image position conversion, the original can be moved together with the original placing glass in one direction or two directions orthogonal to each other, and the original setting position is adjusted. The method to do is also available.

Next, the control unit will be described.

Reference numeral 618 is each load of the registration roller clutch, and 619 is each load of the storage tray paper feed clutch.

The entire copying machine is controlled by a control program stored in ROM 603. The control program is roughly divided into two: one is a program (standby routine) for processing image edit input, copy mode input and the like, and one is a timing control program (copy routine) for the copy process load. The image editing inputs processed in the standby routine are the image area input from the area operation unit and the area layout input from the keyboard. As an example of the load, ON / OFF timing and the like of the erase unit, the optical axis moving motor, the developing drive clutch, the registration roller clutch, and the storage tray paper feeding clutch shown in FIG. 16 are controlled by the input data.

When the initial input area data, area data after layout, and erase data during normal copy are set to the above values (see FIGS. 17 (a) and 17 (b)), erase unit: area data after layout and normal erase Data Optical axis moving motor: Image area data (y ₁ ) and post-layout data (β ₁ ) Registration roller clutch: Controlled by calculation of image area data (x ₁ ) and post-layout data (α ₁ ) It

The erase data calculation will be described with reference to FIGS. 18 (a) to 18 (c). FIG. 11A shows a state in which the image area data for each document input from the area operation unit 612 is stored in a specific address of the RAM 604. The number of image areas for one document is not limited to two. FIG. 2B shows a state in which erase data is stored in a specific address of the ROM 603 for each size during normal copying. Here, X ₁ and X ₂ are the number of clocks that indicate the blinking timing of the erase unit, and Y ₁ and Y ₂ are each half of the selection data of the light emitting element in the erase unit. FIG. 7C shows the calculated erase data for each document. Here, a is the number of clocks per unit length of α ₁ , and Y ₁ (β ₁ ) and Y ₂ (β ₁ , β ₂ ) are erase element selection data changed by β ₁ and β _2. The data is half of each.

The amount of movement of the optical axis is represented by R (β ₁ -y ₁ ), and the value of R changes depending on the zoom magnification when copying the image area. Registration roller clutch ON timing is a (α ₁ + x ₁ ) +
Represented by Z. a is the number of clocks per unit length of α ₁ , and Z is the number of registration roller clutch ON clocks during normal copying.

The ON / OFF timing of the developing drive clutch when there are developing units of a plurality of colors is changed depending on which unit is selected, and the unit corresponding to the input color is also selected.

The storage tray paper feed clutch is driven at a timing to feed the transfer paper stored in the tray when the even-numbered image area is copied.

Reference numerals 620 to 622 are a resistor and a photo interrupter that detect a notch portion of a circular bun having a radial notch portion that rotates in synchronization with the photosensitive drum and emit a clock pulse. The timing of the copying machine is controlled by this pulse number.

Effect The present invention is as described above, and when editing is performed from the first to nth originals, overlapping portions are likely to occur (in layout), but according to the present invention, selection is possible depending on the contents of the originals. By doing so, editing becomes easier.
