Description

[Detailed description of the invention]

[Technical Field] The present invention relates to a copying apparatus, and in particular, when attempting to obtain a desired copy area on a copy paper, the size of the copy paper is detected, and when a magnification is specified, the size and image area of the document corresponding to these are detected. The present invention relates to a copying apparatus capable of displaying images and copying them. [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, in the developing device 5, either the developing roller 5A or 5B is selected according to an instruction to visually develop the toner, and then the cassette 8A or 8
The transfer charger 8 transfers the image onto the copy sheet 312 that is fed from the printer B onto the drum 1 at appropriate timing via the registration rollers 7. In addition, 8A and 8B
is a paper feed roller that feeds 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.
Roller 13. Further, the paper is discharged onto a tray 15 via a paper discharge roller 14. On the other hand, after the transfer paper is separated from the photosensitive drum 1 by the separation charger 1O, the toner is cleaned by a brush or the like in the toner collector 18, and the charge is removed by the pre-exposure rub 2 again, and the next copy is made. Reference numeral 17 denotes a flapper interposed between the roller 13 and the discharge roller 14, and in the case of normal transfer, a flapper. By setting the cover 17 to the position shown by the dotted line, the copy paper 312 is placed in the tray! However, in the case of multiple transfer, the flapper 17 is moved to the position shown by the solid line, and the paper is temporarily stored in the multiple transfer tray 18, and then the paper is transferred from there by the paper feed roller 18 to the registration roller 7.
is guided to the transfer position on the drum l, that is, between the transfer charger 8, and 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. Reference numeral 31 denotes an original for copying placed on a glass original platen 32, and 33 represents an original pressing plate that covers 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 3B 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, scanning is performed while the optical path length until reaching the fixed lenses 38 and 39 is always kept constant. Reference numeral 40 denotes a line sensor composed of a CCD memory that inputs the reflected light image on the document sl 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, conventional analog copying devices, including Carlson process copying machines configured as described above, do not have the ability to copy a desired image area arbitrarily selected on a document onto a desired copying area arbitrarily selected on copy paper. Moreover, it has been impossible to freely change the magnification between the image area and the copy area to perform the above-described copying.

The cassette size display means displays the size of copy paper, the copy area designation means specifies a copy area, and the magnification designation means specifies the magnification of the copy area with respect to the image area. To provide a copying device capable of displaying the size of a document along with an image area corresponding to the image area. Another object of the present invention is to further provide an original moving means, a lens moving means, a cassette moving means, and a registration roller timing control means in addition to the above-mentioned means, and a cassette size display means to display the copy paper size and copy area. When a copy area is specified by the specifying means and the magnification of this copy area with respect to the image area is specified by the magnification specifying means, the corresponding image area and document size are displayed on the image area display means, and the image on such a document is displayed. Copying the area to a desired copying area on a desired copy paper at a specified magnification by driving at least one of the above-mentioned document moving means, lens moving means, cassette moving means, and registration roller timing control means. The purpose of the present invention is to provide a copying device that can perform the following functions. [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 a 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.
On the water side, 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 semi-white board 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
CC
The reflected light image is read in the line along the Y-axis by the pixels of the D sensor 140, and optical scanning is performed in the X-axis direction, so that each line of the Y-axis is first black by the above-mentioned binary code. You can see the coordinates of the position where the color changed from white to 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. 2 uses the Y coordinate of the position where black first changes to white on the Y axis line and the X coordinate of that line based on the binary code from the binarization circuit 144. The B-W maximum value detection circuit 141 uses these X and Y coordinate components as position detection signals.
1 and output to the B-W 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, N, IIv at the corner point 131B. Then the Y coordinate increases to corner point 13
Maximum value Y at 1G? It becomes w-11, after which the transition point from black to white disappears. Therefore, the maximum value detection circuit 148 detects the corner point 131C and outputs the detection signal (Xl, YMIK), and the minimum value detection circuit 147 detects the corner point 131B and outputs the detection signal (
X3 +YY, 1111) can be output to a CPU (not shown). Similarly, in the W-8 detection circuit 148 shown in FIG.
Based on the binary code from the value converting circuit 144, the x and Y coordinates of the position where the color last changed from white to black are detected, and these X, Y coordinates are detected.
The Y-coordinate component is output as a position detection signal to the B maximum value detection circuit 148 and the W-B minimum value detection circuit 150. Therefore, these detection circuits 148 and 150 respectively detect corner points 131 [1 and ! 31A is detected and the detection signal (
X2 , '/gAIB) O and (Xa , Y-asl
) wo'cP, IJ can be output. 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, with reference to FIGS. 4 and 5, a method of calculating the amount of displacement performed for the above-mentioned positional displacement of the original 131 will be explained. FIG. 4 shows a case where the original 131 is placed diagonally in the same state as in FIG.
indicates the normal reference position in which it should be placed. First, in the controller, Y9. When the positions of ~ and Y and the bond are different, it is determined that the original is placed diagonally. Therefore, the deviation angle θ1 at this time is jan'(Y,...
If the document 131 is shifted clockwise around the corner point 131B as in this example, jan'(Y
m, ew-Yrw-h/xl-X3) is a negative value. Further, the example in FIG. 5 shows a case where the original 131 is placed offset in the counterclockwise direction with the corner point 131B as the center. The deviation angle θ2 in this case is jan' (ma, -INI-Y
m # /L −X3), and j
a n -'(v-wN'fat-Ylw, w/L-X
3) By becoming a positive value, the original 131 is placed at corner point 1.
It can be determined that there is a shift in the counterclockwise direction centering on 31B. 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,
In order to further move it to the reference position, in the case of FIG. 4, the document 131 needs to be moved by a distance X3 in the X-axis direction and further by a distance Ylw in the Y-axis direction using the document moving device. In the case of FIG. 5, similarly, the distance X3. Yl, l, 1. in the Y-axis direction. All you have to do is move N. In addition, the manuscript! It is also possible to calculate the size of 31. That is, in the case of FIG. 4, the longitudinal dimension X of the original 131 can be taken as (X+ -) h ) Cos θ1, and the width direction dimension YB can be expressed as CY, % Ys+n, BW
) Melcotcate can be expressed as Cosθ. In addition, in the case of Fig. 5, xL is (X+ X3) Ca
sθ2. Y8 (YMIN4I8-YMIII 4/
) can be expressed as Cosθ2. Next, the document moving device will be explained with reference to FIGS. 8(A) and 8(B). FIG. 6(A) shows a moving mechanism incorporated inside the document pressure plate 133, where 201 is shown in FIG. 8(B).

Here, 438 is a zoom lens disposed in the irradiation optical path toward the drum 1 (see FIG. 1), and in this figure, the X axis is the direction of the irradiation optical path, and the Y axis is the axial direction of the drum 1. The zoom lens 439 is installed on a lens stand 440, and the lens stand 440 is movable along a guide groove 441, and both ends of a wire 443 stretched between pulleys 442A and 442B are attached to the lens stand 440. By concatenating
A stepping motor 444 allows the lens stand 440 to be moved in the X-axis direction. Furthermore, 445 is a lens rotation member capable of linear movement in the Y-axis direction, and one end of the rotation member 445 is slidably held in the guide groove 44B, so that the lens stand 440 can be moved in the X-axis direction.

Image shifting can be performed by laterally moving 8 in the Y-axis direction. As is clear from the above description, in order to move the copied image in the axial direction of the photosensitive drum 1, any of the document moving device, cassette moving device, and lens moving device is used.
It can also be executed with X. That is, FIG. 12 shows a case where the image is shifted in the axial direction of the drum 1 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. 438, 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 30B 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. Further, 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 306, 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 roller 7 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 the problem here is the scanning distance until the registration roller 7 is driven with a certain time delay. Therefore, when moving the copy image 312A to the leading edge of the copy paper 312, the registration roller 7 is driven at a timing that is longer than the above-mentioned fixed time, and the copy image 312A is moved to the rear end of the copy paper 312. When moving the registration roller 7 to the side, the registration roller 7 may be driven at a timing faster than a certain period of time. 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 312 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.

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 when the key 580 is pressed, the fact that the original size selection mode is in effect is indicated by the lighting of LED 580S and the turning off of other LEDs in the same row. 31
Only size No. 2 is displayed on the display section 600. Therefore, when the handler specifies the copy area to be obtained and the magnification on the copy paper 312 and presses the document size selection key 580, the corresponding document
31 is calculated and displayed as a document initialization line 611. 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. 580 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 D590S 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 optimum size of copy paper 312 that meets these conditions is automatically calculated, and the cassette size containing copy paper 312 of that size is displayed on cassette display section 603. In addition, if there is no such cassette size, only the copy line 821 corresponding to the size is displayed, and the L
Eo 58O8 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 CCD sensor 40 and the optical scanning device.
It is possible to obtain the position of the original 131 by pressing the original detection key 530, and to correct the position 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 magnification, and the execution of calculations related to these, but also the size and position of the original 131 before copying. Since the position, cassette size, etc. are all displayed sequentially on the display section 800, the position and size of the document 131 can be detected in conjunction with pressing a copy key (not shown) to start copying, or the position and size can be displayed on the display section 600. The size can be displayed, and 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 or not to make corrections. You can also do that. 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, it is possible to add standard F/RMAT sentences, pages, dates, etc. to the copying apparatus of the present invention using, for example, an internal eraser.
Once the image read by the CCD is displayed on the CRT,
It is also possible to designate an image area on the RT, and it goes without saying that it is also possible to write an image read by a CCD, such as in an LED printer, using an internal eraser or the like. Furthermore, it is also possible to set various areas to predetermined dimensions and select from among the designated areas. [Effects] As described above, according to the present invention, a copy paper display means, a copy area designation means on the copy paper, a display means capable of displaying the original size and image area, and a magnification designation means are provided. , when the copy paper size is displayed by the copy paper display means, the copy area is designated by the copy area designation means, and the magnification of this copy area with respect to the image area is designated by the magnification designation means, the document size is displayed along with this image area.
