Abstract

PURPOSE: To improve an image editing function and operability by copying the overlapped part of the previously inputted original and erasing the over lapped part of the second original, when image regions are overlapped. CONSTITUTION: The first original is illuminated by an exposure optical device for illuminating 8 including a light source 2, mirrors 3-6 and a lens 7, to form an image on a photoreceptor 9 by an exposure. In an original replacing device 1, the first original is taken out and the second original is set in a fixed position. Then, a transfer is performed on the surface having the image of the first original of a transfer paper 14 fed to a transfer position. When the overlapped part appears from a viewpoint of the arrangement of the transfer paper 14 to which the image regions of the first and second originals are copied, the overlapped part of the previously inputted first original is copied and the overlapped part of the second original is erased by an erasing unit provided for erasing in the horizontal direction of an electrostatic latent image in a coping process.

DETAILED DESCRIPTION OF THE INVENTION The structure of the present invention will be described below with reference to the drawings. First, the function of the copying machine, which is the premise of the present invention, will be described based on FIGS. 1, 2, and 3, and then the present invention will be described with reference to FIG.

In FIG. 1, the first original document set at a predetermined position by the original document replacing device 1 is illuminated by an illumination exposure optical device 8 including a light source 2, mirrors 3 to 6 and a lens 7 known per se, and a photoconductor 9 is illuminated. The image is 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 photosensitive member 9 is transferred at a transfer position to a transfer paper 14 as a copy paper supplied from 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. The paper feeding section 12, 13
The transfer paper 14 supplied from the first is clamped by the clamp 17 provided on the transfer drum 15. The transfer paper 14 is clamped by the transfer drum 15 to make one rotation to transfer the image of the first original from the photoconductor 9, and then is temporarily fixed to the transfer drum 15 at a position not contacting the photoconductor 9. Be stored.

A method of changing the distance between the transfer drum 15 and the photosensitive member 9 in order to keep it in a non-contact state with the photosensitive member 9 during storage, or a concave portion is provided in a portion of the transfer drum 15 where there is no transfer paper,
Various methods such as a method of making the concave portion face the photoconductor 9 can be used.

In the above process, the image of the first original is transferred onto the transfer paper, and the first original is taken out by the original replacing device 1 while the transfer paper is being stored by the storage device, and the second original is predetermined. Set to position. Thereafter, the photoconductor 9 is charged and exposed and developed in the same steps as in the case of the first document, and the image of the second document formed on the photoconductor 9 is transferred onto the transfer paper, for example, the transfer drum 15 supplied from 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 can be constructed so that it can be easily replaced manually on the document mounting glass 20 of copy paper, and it also has a feed belt 21 so that a document inserted by hand can be placed at a predetermined position. It is also possible to use a semi-automatic document handling device for feeding and setting or a fully automatic document handling device.

The transfer drum 15 is also used in FIGS. 1 and 2 as a transfer paper storage device 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 so as to avoid direct contact or to stop. 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. 2, the transfer paper is fed from the paper feed units 12 and 13 to the transfer position of the photoconductor 9 by the transfer roller 22 and the guides 23, 24 and 25, or the transfer paper conveying means 27 having the feed belt 26, and the known transfer paper is known. After the transfer by the means, the transfer paper is fixed to the fixing device 18
After being fixed by the above, the sheet is sent to the storage tray 30 through a storage path 29 that is switchably provided by the first gate 28 with respect to the path to the sheet discharge tray 19. When the sheet is fed to the storage tray 30, the tip is always inverted so that the tip is fed, and in the example of the figure, the copy surface is fed downward and stored.

After the transfer paper obtained by copying one sheet or a predetermined number of sheets of the first original is stored in the storage tray 30, copying is performed by the second original. 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.

Storage tray 30 for copying the second original
The transfer paper transporting means 2 which is sent out from the storage tray 30 in advance in accordance with the paper feed roller or the exposure timing in
When the registration roller is stopped by the registration roller provided in the middle of 7, the registration roller is rotationally driven according to the positional deviation calculated by the composite position signal and the information position signal, based on the timing adjustment, and When the composite position of the transfer paper carrying the image reaches the transfer position of the photoconductor 6, the image of the information of the second original formed on the photoconductor 9 is adjusted to the transfer position. The transfer paper is stored in the storage tray 30 in the number corresponding to the original to be combined, and is repeatedly sent to the transfer position of the photoconductor 9 repeatedly.

Upon completion of the composite copying of the final original, 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 reversed from the case where the transfer paper is sent to the storage tray 30 through the first gate 28. In addition, the switching path 32 is not fed after passing through the straw fixing device, and is fed to the storage tray in a state in which the front side is the rear end with the copied surface facing upward in the figure.
Can be provided. 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 of the transfer paper, which is opposite to the surface opposite to the previous one, comes into contact with the photoconductor and is transferred. It enables double-sided copying of straw.

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. it can. That is, the above synthetic copying operation is performed on one side, and then the storage tray 30 is sent from the second gate 31 through the switching path 32,
After that, the above-mentioned synthetic copying operation is performed again on the back side, whereby double-sided synthetic copying is possible.

Incidentally, reference numeral 33 in FIG. 3 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 operating portion of the copying machine according to the present invention, and the operating mechanism will be described with reference to this drawing. 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,

When copying, it is preferable to operate the keys on the left side of the operation unit, and the functions will be described from the keys on the left side.

Left blank, right blank keys 45, 46
If you want to create a binding margin of 15 mm on the left side of the transfer paper copied with the binding margin adjustment key, use the left blank key 45
When pressing 15 and inputting 15 with the 10 key 34, the 7-segment display on the upper portion of the display 49 lights up as "15". This may be blinking, and when the left blank key 45 is released, "15" disappears and it returns to "1". The same applies to the right blank key 46.

The composite copy key 48 is used for the first original and 2
Use this when you want to copy the first original in a stack.

The reverse paper ejection key 47 is used when the transfer paper after copying is turned upside down and is to be output to the paper ejection tray 19. When copying from the first original, the ejected transfer paper is Since the lower side is the first copy, if it is turned upside down, if a large number of ejected transfer papers are turned upside down, they will be misaligned in order from the first.

The stack key 43 and the sort key 44 are publicly known ones without any explanation.

The double-sided copy key 42 for a double-sided original or a single-sided original is used when a double-sided copy is desired. There are cases where a double-sided original is copied to a double-sided copy and a single-sided original is copied to a double-sided copy.

The paper feed selection key 40 is used for the paper feed trays 12, 1
3 is selected, and A4 is displayed on the display section 49 for the first sheet feed tray and B is displayed for the second sheet tray and the third sheet tray.
If A4 and A3 are set and the first stage is selected, the A4 display section is surrounded by a frame. When the user wants to select the second stage, pressing the paper feed selection key 40 moves the frame to the second stage and the second stage is selected.

In order to set the magnification, there are an enlargement key and a reduction key (magnification setting key 41). When they are pressed, the percentage is displayed on the display section 49 in 1% increments. If, for example, "71%" is displayed, "A3 →
"A4" is also displayed to inform that the magnification is to reduce A3 to A4.

The ten keys 34 from 1 to 9, 0 are for setting the number of sheets, and are displayed in the seven segments above the display unit 49. The lower 7-segment display is for displaying the number of copies. Further, as described above, it is also used when the left and right blank keys 45 and 46 for adjusting the binding margin are pressed and the binding margin width is set by the 10 key 34. Although there is an enlargement / reduction key in the figure, it is also possible to use this key 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 required during copying. When the urgent key 35 is pressed, the copying is interrupted, and when the urgent copy is performed, the interrupt key 35 is pressed again to return to the previous mode. Copying can be resumed.

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 a magnification of 100% (actual size) is set for A4 size, it will be used by the previous person. The selected mode is A3 size 7
If the reduction mode is 1% and the copy mode is double-sided copy mode,
In order to save the trouble of canceling these, it is possible to change the magnification to 100% in A4 size only by pressing the standard mode setting key 39.

The above is the description of the keys. In the case of the figure, the left plank, the right blank keys 45 and 46, the composite copy key 4
8 shows an example in which the reverse paper ejection key 47 is covered because the key is not always used.

The F key 51 is used to automatically feed a document, and the SADF key 52 is used to manually insert a document, and both are well known.

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

The automatic paper feed selection (APS) key 54 is
This is used when the size of the original is detected and the transfer paper in the paper feed tray is automatically selected so as to have the set magnification.

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

On the display panel shown in FIG. 7A, a document jam display 57, a set confirmation display 58 that lights up when the document is not completely set, and a state in which copying is started if the document is set in the SADF mode There are an original feed display 59 that is sometimes lit and an original insertion display 60 that indicates the direction in which an original is to be inserted and that turns off when inserted.

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

The display uses a CRT.

FIGS. 6A to 6G show the contents of the CRT screen.

In FIG. 6A, 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 original. 65 is
This is a part of the second manuscript. Further, 66 is a part of the third original. The character display below the scales 62 and 63 indicates 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. First
The original is copied at the same size as shown in the character display. Second
The original document 65 is copied at a reduction of 93% as shown by the character display.

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

In FIG. 6D, 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 placed in a reduction mode of 93% in the part shown in the figure. Part 66 of the third original is copied in the enlargement mode of 115%.

In FIG. 6E, 64 is a part of the first original. Reference numeral 65 is a part of the second original. 66 is a part of the third original. 65 and 66
Shows that 65 is preferentially copied although they partially overlap. Reference numeral 64 indicates the position occupied by the copy, which is the same size, 65 is the reduction of 93%, and 66 is the reduction of 87%.

In FIG. 6 (f), 64a and 64b are parts of the first original. Reference numeral 65 is a part of the second original. Similarly to (e) in the figure, 64b and 65 have a partial overlap, but 65 is preferentially copied.

In FIG. 6G, 64a and 64b are parts of the first original. Reference numeral 65 is a part of the second original. 64b and 65 partially overlap, but depending on the contents copied to 64a and 64b, both need to be copied (that is, the case where priority is not given).

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

When there are priorities as shown in (e) and (f) of the same figure, the display attributes such as red, yellow, blue, etc., or the solid line, the broken line, the one-dot chain line, etc., are displayed in descending order of priority. It is also possible to decide in advance.

The numerals in 64, 65 and 66 shown in FIG. 9A indicate the order of the originals. Color CRT is the first
If it is determined in advance that the second document is red, the second document is yellow, and the third document 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. The pressure-sensitive sheet 67, which uses a pressure-sensitive sheet for detecting the position of the original, has signal lines for inputting and outputting each matrix signal on the x-axis and y-axis, and a scan signal from the I / O controller 68 in the block diagram. The position information can be input by.

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, an area shift key, (left, right, up and down), a zoom key (up,
Down) and color designation keys (black, red, blue).

The determination as to whether the key is pressed is based on the scan signal for key code detection and the I / O signal when the scan signal is pressed when the key is pressed.
It depends on the matrix signal of the return signal returned to the controller 68.

Explaining the operation keys,

[1] The edit start key is a key for notifying the start of editing of a document, and if this key is pressed, the position information of the pressure sensitive sheet 67 is canceled.

[2] The edit end key is a key for notifying the end of the editing of the document, and when this 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.

[3] The priority key is pressed when a document is desired to be secured with priority when areas of a plurality of documents are overlapped. RA that stores the number of documents when this key is pressed before, after, and in the middle of area designation
The priority flag is set in M.

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

The y-axis direction data of the data contents 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 RAM y
The axis position data is updated.

For the 693 and 694 keys, x in the RAM
The axis position data is updated.

[5] The zoom key is a key to be pressed when changing the size of the image in the area frame, and can be steplessly specified in the enlargement and reduction directions.

[6] The color designation key is a key to be pressed when multicoloring (color designation) is performed on copy paper.

[7] The pressure-sensitive sheet key determines the position information of the editing area frame and is valid while the editing end key after the editing start key is pressed, and the x-axis and y-axis scan signals and the scan signal.

The area surrounded by the four corners inside the transfer paper is the image editing area. 11 (a) and 11 (b)
FIG. 12 is a diagram showing a region shift state, and FIG. 12 shows R at that time.
It is an AM map. 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 is 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 machine shown in FIG. 1, the original placed on the original placing glass 20 is illuminated by the light source 2, and the image of the original is transferred to the photoreceptor 9 by the mirror groups 3 to 6 and the lens 7.
It is projected in a slit shape.

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

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

I) The magnification conversion in the mirror scanning direction is determined by the relative relationship between the surface speed v0 of the photosensitive member 9 and the first mirror scanning speed v. If the magnification is m, then m = (v0 / v)

(This is not the case with a full-exposure copying machine such as flash exposure.)

Ii) The magnification conversion in the direction perpendicular to the above i) (the 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 optical path direction by an amount (Δa) that matches the magnification m,
This is achieved by displacing the mirrors 5, 6 to correct the total path by Δl. Letting the focal length of the lens be l, Δa = ((1 / m) -1) f Δl = (m + (1 / m) -2) f

When a zoom lens is used, 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 paper, that is, the contact timing of the transfer paper 10 to the photoconductor at the time of transferring the toner image formed on the photoconductor. To be done.

(The timing relationship between the photosensitive member and the transfer paper may be kept constant and 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 optical path of the lens. FIG.
In the case of exposing the information in the partial range a of the document range A in 3, 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 (1/2) in the direction orthogonal to the optical axis, the lens 7 is moved from the partial area b on the photoconductor to the partial area b ′ moved by the distance 1 in the moving direction of the lens 4. 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.

By using the magnification conversion by moving the lens 7 along the optical axis, it is possible to perform the variable magnification copying for changing the copying magnification and the 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, FIG.
4 and FIG. 15, the lens base 73 for fixing the lens 7 is supported by the lens placket 74, and the lens bracket 74 is screwed to the screw shaft 76 rotatably supported by the optical system frame 75. Direct motor 77
It is possible to use a structure in which the lens 7 is moved in a direction orthogonal to the optical axis by reversible rotation by the motor 77 via a belt or the like. Lens bracket 74
If the movement is guided by a guide bar 78 fixed to the optical system frame 75, the lens can be smoothly reciprocated without tilting. Optical system frame 75
As in the case of FIGS. 14 and 15, the zoom lens can be magnified by screwing it onto a screw rod or the like so as to be movable in the optical axis direction.

For image position conversion, in addition to the method of controlling the feed timing of the copy paper and the control of the movement of the lens, the original can be moved together with the original placing glass in one direction or two directions orthogonal to each other so that the original is set. A method of adjusting the position is also available.

Next, the control unit will be described.

The entire copying machine is controlled by the control program stored in the ROM 603. The control program is roughly divided into two: one is a program (standby routine) for processing image edit input, copy mode input, etc.
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, 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.
N / OFF timing and the like are controlled.

Image area data x1 x2 y1 y2

Area data after layout α1 α

If the initially input area data, the area data after layout, and the erase data at the time of normal copy are set to the above values (see FIGS. 17A and 17B), erase unit: area data after layout And normal erase data Optical axis movement motor: Image area data (y1) and layout data (β1) Registration roller clutch: Image area data (x1) and layout data (α1) .

The operation of the erase data is shown in FIG.
An explanation will be given based on (c). The area (a) in FIG.
The image area data for each original input from the RAM 12
The state stored in the specific address 604 is shown. The number of image areas for one document is not limited to two. FIG. 6B shows a state in which erase data is stored in a specific address of the ROM 603 for each size during normal copying. Here, X1 and X2 are clock numbers indicating the blinking timing of the erase unit, and Y1 and Y2 are each half of the selection data of the light emitting element in the erase unit.
FIG. 3B shows the calculated erase data for each document. Here, a is the number of clocks per unit length of α1, and Y1 (β1, β2), Y2 (β1, β2)
Are half and half of the erase element selection data changed by β1 and β2.

The amount of movement of the optical axis is represented by R (β1-y1), and the value of R changes depending on the zoom magnification ratio at the time of copying the image area. The registration roller clutch ON timing is
It is represented by a (α1-x1) + Z. a is the number of clocks per unit length of α1, 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 so as to feed the transfer paper stored in the tray when the even-numbered image area is copied.

Reference numerals 620 to 622 are resistors and photointerrupters which detect the cutout portion of a circular bun having a radial cutout portion which rotates in synchronization with the photosensitive drum and emit a clock pulse. The timing of the copying machine is controlled by this pulse number.
