Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a copying apparatus, and in particular, it is capable of developing multiple colors, specifying colors, and performing multiple transfers. The present invention relates to a copying device capable of copying in a copying area. [Prior Art] Fig. 1 shows an example of a conventional copying apparatus capable of copying onto ordinary paper using a photosensitive drum, in which 1 is a seamless photosensitive member whose surface is made of a photoconductive material. , is a photosensitive drum that can rotate in the direction of the arrow. During one rotation of the photosensitive drum 1, the photosensitive drum 1 is first neutralized by the exposure lamp 2, then corona charged by the primary charger 3, and when it rotates to position 4, it is image exposed and electrostatically charged. A latent image is formed. After that, - either the developing roller 5A or 5B is selected according to an instruction in the developing unit 5, and the toner is visually developed, and then the toner is transferred from the cassette 6A or 6B via the registration roller 7 at an appropriate timing. The transfer charger 8 transfers the image onto the copy paper 312 that is fed onto the drum 1. In addition, 9A and 8
B is a paper feed roller that feeds the paper 312 from the cassettes 8A and 6B. After the transfer, the copy paper 312 is separated from the drum 1 by the separation charger 10, guided by the conveyor belt 11 to the fixing roller 12, where it is thermally fixed by pressure heating.
The sheet is discharged onto a tray 15 via rollers 13 and further through discharge rollers 14. On the other hand, after the transfer paper is separated from the photosensitive drum 1 by the separation charger 10, the toner is cleaned by a brush or the like in the toner collector 16, and the charge is removed by the pre-exposure rub 2 again, and the next copy is made. 17 is interposed between the roller 13 and the paper discharge roller 14. For normal transfer, use flapper 17.
is located at the position indicated by the dotted line, so that the copy paper 312
is guided toward the tray 15, but in the case of multiple transfer, the flapper 17 is moved to the position shown by the solid line, so that it is temporarily stored in the multiple transfer tray 18, and then from there it is guided by the paper feed roller 19. It is guided to the registration roller 7 and transferred to the transfer position on the drum 1 again, that is, the transfer charger 8.
The transfer and fixing steps are repeated. Note that 20 is a blank exposure device for preventing unnecessary toner from adhering to the drum 1, and has a subdivided structure. Next, a device for optically reading an image from a document and a device for irradiating the image onto the drum 1 will be described. 31 is an original for copying placed on a glass original table 32, and 33 is an original pressure plate covered on the upper surface of the original 31. The light reflected from the original 31 can be effectively obtained by the original pressure plate 33. Reference numeral 34 designates an illumination lamp that is integrally constructed with the first scanning mirror 35 and operates in the scanning direction.Furthermore, the second reflection mirror 38 is integrated with the third reflection mirror 37, and these mirrors 36 and 37 are integrated with the first scanning mirror 35. Since the scanning mirror 35 and the like are configured to be moved at half the scanning speed, the optical path length until reaching the fixed lenses 38 and 38 is always kept constant during scanning. 40 is a line sensor composed of a COD memory that inputs the reflected light image on the document 31 obtained through the lens 38; at the same time, the reflected light image is reflected by the fourth reflecting mirror 41 through the lens 38, and is exposed to light. Latent image formation position 4 on drum 1
is projected on. Further, 42 is a standard white board used to correct variations in the amount of light and pixels when reading an image by the CCD sensor 40, and 43 is a standard black board for detecting the edge of the original 31. However, in conventional analog copying devices such as Carlson process, it is possible to edit images on copy paper by multiple-transferring desired image areas to desired copying areas. There was no one that had the ability to specify colors each time. [Object] In view of the above-mentioned problems, an object of the present invention is to enable copying of a desired image area on a document to a desired copying area on copy paper by various means such as document moving means, and furthermore, to It is an object of the present invention to provide a copying apparatus which has a transfer means and a selectable plural color developing means and is capable of editing a colored image in a desired copy area on copy paper. [Example] The present invention will be described in detail below based on the drawings. Note that in the following description of parts having the same functions as those in FIG. 1, reference will be made to FIG. 1, and the same reference numerals will be used. FIG. 2 shows an example of the configuration of the document coordinate detection device according to the present invention. In this example, the surface of the document pressure plate 133 on the side facing the document table 132 is made of a color with low reflectance, for example, black. Also,
A CCD sensor 140 transmits a reflected light image from a document 131 held between a document table 132 and a pressure plate 133 to a lens 138.
In this example, the output from the CCD sensor 140 is sent to the amplifier 1.
41, and further converted into a digital value by an A/D converter 142. Then, this digital value is compared with the standard value read from the tank double white plate 42 shown in FIG.
Binarizes the image into white or black. Now, as shown in FIG. 3, the original 131 is placed on the original platen
32, the CCD
The reflected light image is read by the pixels of the sensor 140 along the Y-axis, and optical scanning is performed in the X-axis direction, so that each Y-axis line starts from black using the above-mentioned binary signal. You can see the coordinates of the position where it turned white and the coordinates of the position where it last changed from white to black. That is, the shaded area in FIG.
This is a portion where the reflected light is black because the surface of a document pressure plate 133 (not shown) covered on the top surface is black or the like. Therefore, the B-W detection circuit 145 shown in FIG.
Then, based on the binary signal from the binarization circuit 144, detect the Y coordinate of the position where black first changes to white on the Y axis line and the X coordinate of that line, and calculate these X and Y coordinate components. As a position detection signal, the B-W maximum value detection circuit 14
B and -B-111 are output to the minimum value detection circuit 147. Now, when scanning in the X-axis direction is performed, if we trace the trajectory of the position where the color changes from black to white in FIG. After that, the Y coordinate of the change position gradually decreases and reaches the minimum value Y+-p-eV at the corner point 131B. Then the Y coordinate increases to corner point 13
At 1C, the maximum value Y19 (-eV is reached, and after that the point of change from black to white disappears. Therefore, the maximum value detection circuit 146 detects the corner point 131C and outputs the detection signal (X, , Y). , the minimum value detection circuit 147 detects the corner point 131B and outputs the detection signal (X3
+YMIN-trw) can be output to a CPH (not shown). Similarly, the B detection circuit 148 shown in FIG. ,
The Y coordinate component is output as a position detection signal to the W-B maximum value detection circuit 148 and the G-B minimum value detection circuit 150. Therefore, these detection circuits 1411 and 150 have corner points 13111 and 13!, respectively. A is detected and the detection signals (X2, Ym'11B) '13 and (Xa +YP
II, 1-ve) can be output from the CPU axis. In this way, it is possible to cause the CPU (not shown) to perform various calculations as will be described later based on these position detection signals, and to operate the control device for obtaining proper copies. Next, according to FIGS. 4 and 5, the document 13 as described above! A calculation method for calculating the amount of positional deviation will be explained. Figure 4 shows the case where the original 131 is placed diagonally in the same condition as in Figure 3, and the frame indicated by the broken line is the original 131.
indicates the normal reference position in which it should be placed. First, the controller determines that the document is placed diagonally when Yrw, vW and Y, bond position coordinates are different. Therefore, the deviation angle θ1 at this time is jan'(Y, N6
w-Ym1w/XI
'(YMl, Iw-Y, , vd/XI-X3) can be determined based on the negative value. Further, the example in FIG. 5 illustrates a case where the original 131 is placed offset in the counterclockwise direction with the corner point 131B as the center. In this case, the deviation angle θ2 is tan' (YNIN, B1
7--1/XI X3), ja
n'(V,N-Yibon/L-)h) By taking a positive value, it can be determined that the original document 131 is shifted in the counterclockwise direction around the corner point 131B. can. Thus, in order to correct the position of the document 131 placed in this way, in the case of FIG.
All you have to do is move it counterclockwise by 01 degrees.
Furthermore, in the case of FIG. 5, the document 131 may be rotated by an angle of 02 degrees clockwise about the corner point 131B. In this way, after correcting the orientation angle of the original 131,
To further move the document 131 to the reference position, use the document moving device again to move the document 131 in the X-axis direction by a distance x3 in the case of FIG. 4, and further by a distance Y1 . In the case of Fig. 5, you only need to move by x3 in the X-axis direction in the same way. It is sufficient to move by Y, ... in the Y-axis direction. Note that the size of the original document 131 can also be calculated. That is, in the case of FIG. 4, the longitudinal dimension X of the original 131 can be taken as (XI - X3 ) Cos θ1, and the width direction dimension YR can be expressed as
, it can be written as the poem Eosθ. In addition, in the case of Fig. 5, xL is (Xl - X3

Image shifting can be performed by laterally moving 9 in the Y-axis direction. As is clear from the above description, the copy image can be moved in the axial direction of the photosensitive drum 1 using any of the document moving device, the cassette moving device, and the lens moving device. That is, FIG. 12 shows a case in which the image is shifted in the axial direction of the drum l by the document moving device. In this case, by moving the document 131 to the position indicated by the broken line in the axial direction, the reflected light image is shifted to the lens. 439, the image is formed on the drum 1 at the position indicated by the broken line, and a copy image 312A is obtained by shifting to the position indicated by the broken line on the copy paper 312. FIG. 13 shows a case where a similar shift is executed by a cassette moving device. In this case, by moving the cassette 306 to the position shown by the broken line, the copy paper 312 stored in the cassette 306 is moved to one point on the drum 1. Since the paper is fed to the position shown by the chain line, a copy image 312A is obtained on the copy paper 312 at the position shown by the solid line. Furthermore, FIG. 14 shows a case where the image is shifted by a lens moving device. In this example, there is no need to move the original 131 and the cassette 30B, and only the lens 438 is moved in the axial direction of the drum 1. Therefore, copy paper 312
A copy image 312A can be obtained at the position indicated by the broken line. Next, the copy image 312A is scanned in the scanning direction, that is,
To shift in a direction perpendicular to the axis of drum 1, use the 15th
This is also possible by adjusting only the registration timing of the registration rough as shown in the figure. In the conventional case, the image leading edge is aligned with the copy paper 312 by driving the registration rollers 7 after a certain period of time of scanning starting from the image leading edge 131L of the original 131. Note that m here is the scanning distance until the registration roller 7 is driven with a certain time delay. Therefore, the copy image 312A is moved to the leading edge side of the copy paper 312. When moving the copy image 312A to the rear end side of the copy paper 312, the registration roller 7 is driven at a timing faster than the fixed time described above. The registration roller 7 may be driven. Therefore, by driving the registration rollers 7 at an accelerated timing, for example, by advancing the copy paper 312 by the dimension text, it is possible to move the image on the original 131 to a position P' close to the trailing edge on the copy paper 312. can. In this case, the image can be moved to a similar position P' on the copy paper 310 by moving the original 131, for example, to the left in this figure by the dimension text using the original moving device. Note that it goes without saying that the adjustment of the registration timing described above and the movement of the document 131 by the document moving device may be used together.

Therefore, the desired image area on the original document 131 and the desired copy on the copy paper 312 are selected by the handler by various operations on the group of desired area designation keys described above. Assuming that the copy area has been specified and the key 565 is pressed, the magnification of the copy area with respect to the image area is automatically calculated, and the magnification is displayed on the magnification display section 601. In this case, the x:Y ratio for the area designated first is stored in the CPU (not shown), and when specifying the area later, the X:Y ratio of the previously stored area is stored. line 610 while corresponding to the ratio of
Or line 620 moves. 570 is an automatic copy area selection key. Pressing the key 570 indicates that the copy area automatic selection mode is active.
This is indicated by the lighting of EII 57O3 and the turning off of other LEDs in the same row. In this case, the size of the original 131 is automatically detected, and the size of the specified copy paper, that is, the cassette, is displayed on the display section 600. Is displayed. Therefore, when the handler specifies a desired image area on the document 131 and specifies the magnification by operating the magnification designation key 501 and the borrow variation keys 502 and 503, and then presses the area selection mode key 570. , the area to be copied on the copy paper 312 is automatically calculated and displayed as a copy line 620. In this case, further press the copy area key 512,
It goes without saying that by operating the keys 515 to 522, it is possible to move the copy line 620 vertically and horizontally while keeping it in this state. 575 is an automatic image area selection key. By pressing the key 575, the image area automatic selection mode is indicated by the lighting of the LED 575S and other lights on the same line.
The size of the document 131 is automatically detected in this case as well, and the specified size of the copy paper 312 is further displayed on the display section 600. Therefore, when the operator specifies the copy area and magnification on the copy paper 312 and presses the image area selection key 575, the image area on the document 131 is automatically calculated and the image line 610 is It is displayed on the display section 600. In this case, by further pressing the document area key 513 and operating the keys 515 to 522, it is possible to move the image line 610 vertically and horizontally while maintaining its shape. Reference numeral 580 is an original size selection key, and by pressing the key 580, the fact that the original size selection mode is in effect is indicated by lighting up LED 58O3 and turning off the other LEDs in the same row. In this case, the specified copy paper is selected. 31
Only size No. 2 is displayed on the display section 600. Therefore, when the handler specifies the copy area to be obtained on the copy paper 312 and the magnification, and presses the document size selection rate -580, the size of the corresponding document 131 is calculated. Initialize the original 1 in 61
The size is displayed as 1. Note that the image area on the original document 131 and the copy area on the copy paper 312 can be set automatically or manually by the key operations on the operation unit 500 described above. Copying the image area to the copy area can be accomplished using a series of means such as the document moving device, lens moving device, and cassette moving device described above. Further, by operating the developer switching key 545 to specify the color for copying, or by operating the multiplex mode key 550, the copy paper 312 is temporarily held in the intermediate tray 18 and the next specification is made, thereby editing the image. Furthermore, it is also possible to specify a color each time a copy is made. 590 is an automatic cassette selection key. Pressing the key 590 indicates that the cassette automatic selection mode is present.
This is displayed by turning on the D580S and turning off the other LEDs in the same row, and in this case, only the automatically detected document size is displayed on the display section 600. Therefore, the handler specifies the image area on the document 171 and the magnification, and then presses the automatic cassette selection key 590.
When is pressed, the optimal size of copy paper 312 that meets these conditions is automatically calculated, and the cassette size that accommodates copy paper 312 of that size is displayed on the cassette display section 803. In addition, if there is no such cassette size, only the copy line 621 corresponding to the size is displayed and the L
ED 590S is flashed. In the above explanation, the case where the document size is detected by a combination of an optical scanning device and a CCD line sensor 40 has been explained, but in this case, as mentioned above, pre-scanning before copying is required. Ru. Therefore, an area sensor (not shown) can be used in addition to the CCN scan sensor 40 and the optical scanning device.
The position of the original 131 can be obtained when the original detection key 530 is pressed, and the position can be corrected by driving the original moving device while viewing the positional deviation displayed on the display unit 600. Needless to say. As described above, the operation unit 500 not only allows inputting the selection of the size and position of the image area and the copy area, the setting of the double height, and the execution of calculations related to these before copying, but also the size of the original 131. , position, cassette size, etc. are all sequentially displayed on the display section 800. Therefore, the position and size of the document 131 can be detected in conjunction with pressing a copy key (not shown) to start copying, and the display section 600 can display the position and size of the document 131. If the document 131 is in an incorrect position, the start of copying is suspended for a certain period of time regardless of whether the copy key is pressed, and the handler is alerted and asked whether corrections are possible. You can also. Therefore, if the document moving device is not driven or the document pressure plate 133 is not manually released within a certain period of time, it is assumed that the handler has approved the incorrect position, and the copying operation is automatically started, or the copying operation is restarted. It is also possible to start the operation only when the button is pressed. Furthermore, in the case of multiple transfer, it is also possible to edit a colored image by setting the color specification order in advance and executing multiple transfer according to this order.
Also, for example, by using an internal eraser or the like, the fixed yt! iFOR
It is also possible to add MAT sentences, pages, dates, etc. [Effect] As explained above, according to the great invention, the document moving means,
By driving at least one of the lens moving means, the cassette moving means, and the registration roller timing control means, a desired image area on a document can be copied to a desired copying area on copy paper, and the desired image area can be selected. By providing a multi-color developing means and a multiple transfer means, it has become possible to edit a color image in a desired copy area on copy paper. In the above explanation, it has been described that the color is specified for each copying operation, but it is possible to specify the color for each copy sheet on which multiple transfers are made. Needless to say, it is also possible to perform multiple transfers using a plurality of colors in one designated copy area. In addition, it can be linked to a general-purpose automatic document feeder to perform color editing according to a preset mode, and if the mechanism is capable of double-sided copying, it can also be linked to this. It is also possible to perform similar color editing by
