Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus such as a digital copying machine, a laser printer, a facsimile machine, or the like. More specifically, a document of a predetermined size is divided into two recording paper sheets of a predetermined size. The present invention relates to an image forming apparatus for performing a moving process or a reducing process so as not to divide a character string when a manuscript is a table figure having an improperly divided character string such as a title or a note when recording. is there.

[0002]

2. Description of the Related Art First, the background of the technology according to the present invention will be described. In the office environment, there are many documents of different sizes, and the documents are bound and bound in files and stored / stored in a desk, a cabinet, or the like. Generally, private companies use A4 size or A3 size.
A size document such as size is often used. On the other hand, in public offices, B size documents are often used for reasons such as laws and ministerial orders. As described above, in the past, documents of A size and B size were mixed, and the work of storing and managing the documents was troublesome.

Under these circumstances, the government has recently planned to unify the document sizes, and newly created documents will be based on the uniform size (A size) in the future. However, the already created document is stored as a B5 size original, and if a copying machine is used to copy this document, it is generally B.
It is to be copied on 5 size recording paper. Recent copying machines have a function of detecting the size of a document, automatically selecting a recording sheet that matches the size of the document, and forming an image on the fed recording sheet. In such a copying machine, forming an image on a recording paper having a size different from the size of the original makes the operation rather complicated. Further, in a copying machine that does not have such a function, when recording sheets of a plurality of sizes are set, the operator often selects the recording sheet of the same size as the original.
Therefore, in order to unify the document sizes in the office, a copier that can set only recording paper of a predetermined size is required.

As one means for solving such a problem, it is known that a large original is divided into two and copied. For example, as a reference technical document related to the present invention, there is a "copying method" disclosed in Japanese Patent Application Laid-Open No. 60-146255. This is for a large size manuscript
This is a continuous page copying method of recording on a small-sized recording sheet. This copying method is an effective means when recording each page on a separate recording sheet with the book opened, and since the image originally contained in each page is recorded, there is no image in the central portion.

[0005]

However, in the conventional copying method as described above, for example, an A3 size original as shown in FIGS. 8 and 10 has characters such as titles and cautions. In the case of a table with columns, if you simply divide it into two parts with the central part as the boundary and output them to A4 size recording paper, the character string will be divided in the central part and the contents of the table will be divided. Was difficult to understand, and the aesthetics of the table were impaired.

The present invention has been made in view of the above, and when a document of a predetermined size is divided into two and recorded on a recording sheet of a predetermined size, the division of a title, a caution, etc. is not necessary. If the front image with appropriate character strings is a manuscript, the purpose is to obtain a good image that does not impair the mutual relationship.

[0007]

In order to achieve the above object, the present invention has a document reading unit for reading image data from a document, a document size detecting unit for detecting the size of the document, and a recording paper size detecting unit. Recording paper size detection means for
Image recognition means for recognizing the type of image data read by the document reading means, input means for inputting the type of image data, and a range of information in which image data is inappropriately divided, and input data by the input means And storage means for storing the image data read by the document reading means, image processing means for selectively performing division / reduction / movement processing on the image data, and image processing means after image processing by the image processing means. An image forming apparatus including an image writing unit that writes image data on a recording sheet.

Further, the image processing means, based on the detection results of the original size detecting means and the recording paper size detecting means, when the original size is larger than the recording paper size,
The read image data is divided into two, and divided images are formed on the recording paper.

Further, the image processing means divides the image data into two and forms divided images on the recording paper respectively,
The information is moved to a predetermined position so as not to divide inappropriate information such as titles and notes.

Further, the image processing means executes a reduction process on the information even if the information such as a title and a note is improperly divided and is still divided on the recording paper. It is a thing.

Further, the input means is for designating, by coordinates, a range of information in which image data such as a title and a note are inappropriately divided.

Further, the image recognition means recognizes information outside the outer frame of the front image as information which is inappropriately divided.

[0013]

The image forming apparatus according to the present invention recognizes that the original image is a front image by the input means, and the range of the information such as the title and the caution note added to the front table is inappropriate for image recognition. The means recognizes whether the image data is a character or a ruled line, stores the input data and the image data read by the document reading means in the storage means, and records the document size for the image data by the image processing means. When the image data is larger than the paper size, the image data is divided. At this time, based on the data input by the input means and the judgment of the image recognition means, the information added to the table which is inappropriate to divide is displayed at the division position. In some cases, reduction processing and movement processing are selectively executed.

[0014]

Embodiments of the image forming apparatus according to the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic configuration of an image forming apparatus according to the present embodiment. The image forming apparatus is roughly classified into a copying apparatus main body 100 and an automatic document feeder (AD).
F) 200, sorter 300, double-sided reversing unit 40
It is composed of four units, 0.

FIG. 2 shows the construction of the copying apparatus main body 100, which is provided with a scanner section, a writing section, a photoconductor section, a developing section, and a paper feeding section. The configuration and operation of each of these parts will be described in detail below.

[Scanner Unit] The scanner unit includes the reflecting mirror 10.
1, a first scanner equipped with a light source 102 and a first mirror 103 and moving at a constant speed, and a second mirror 1
04 and a third mirror 105, and a second scanner which follows the first scanner and moves at a speed half that of the first scanner. An original document (not shown) on the contact glass 106 is optically scanned by the first scanner and the second scanner, and the reflected image is scanned by the color filter 1.
It is guided to the lens 108 via 07 and forms an image on the one-dimensional fixed image pickup element 109.

As the light source 102, a fluorescent lamp or a halogen lamp is used, but a fluorescent lamp is generally used because of its stable wavelength and long life. In this embodiment, the reflecting mirror 101 is attached to one light source 102, but two or more light sources 102 may be used. Since the fixed image pickup device 109 described above has a constant sample clock, the fluorescent lamp will adversely affect the image unless it is lit at a higher frequency.

As the fixed image pickup element 109, CC is generally used.
D is used. The image signal read by the fixed image pickup device (hereinafter, referred to as CCD image pickup device) 109 is an analog value, and thus is analog / digital (A / D) converted,
Various kinds of image processing (for example, binarization processing, multi-value processing, gradation processing, scaling processing, editing processing, etc.) are performed on the image processing board 110, and converted into a digital signal as a set of spots.

In order to obtain color image information, in the present embodiment, a color filter 107 that allows only necessary color information to pass through is arranged in the optical path leading from the original to the CCD image pickup device 109. The color filter 107 is put in and taken out in accordance with the scanning of the original, and the functions such as multiple transfer and double-sided copy are activated each time, so that various kinds of copies can be created. Further, the marker on the original image can be read in the copy mode.

[Writing Section] The image information after the image processing is
In the writing unit, the data is written on the photosensitive drum 111 in the form of a set of light spots by the raster scanning of the laser light.
As the laser light source, a He-Ne laser has been conventionally used. The wavelength of He-Ne laser is 633 nm.
The laser light source itself is very expensive, and since the laser light source itself cannot be directly modulated, the device becomes complicated. By increasing the sensitivity of the photoconductor in the long wavelength region, inexpensive semiconductor lasers that can be directly modulated have been used. Also in this embodiment, this semiconductor laser is used as a laser light source.

3 (a) and 3 (b) are a plan view and a side view of the writing section, in which the laser light emitted from the semiconductor laser 112 is converted into a parallel light flux by the collimator lens 113, and the aperture 114 is used. It is shaped into a light beam with a fixed shape. The shaped laser light enters the polygon mirror 116 in a form compressed by the first cylinder lens 115 in the sub-scanning direction.

The polygon mirror 116 has an accurate polygonal shape and is rotated by a polygon motor 117 in a fixed direction at a fixed speed. This rotation speed is the rotation speed of the photosensitive drum 111, the writing density, and the polygon mirror 11.
It is determined by the number of faces.

The reflected laser light incident on the polygon mirror 116 is deflected by the rotation of the polygon mirror 116. The deflected laser light is reflected by the fθ lens 118.
A and 118b are sequentially incident. fθ lens 118a, 1
Reference numeral 18b converts scanning light having a constant angular velocity so as to scan the photosensitive drum 111 at a constant speed, forms an image on the photosensitive drum 111 so as to form a minimum light spot, and further has a surface tilt correction mechanism. ing.

The laser light that has passed through the fθ lenses 118a and 118b is guided to the synchronization detection sensor 120 by the synchronization detection mirror 119 outside the image area, and the image is obtained after a certain time has elapsed since the synchronization signal for issuing the cue signal in the main scanning direction was issued. Data is 1
Lines are output, and this is repeated to form one image.

[Photosensitive Member] A photosensitive layer is formed around the photosensitive drum 111. Semiconductor laser light (wavelength 780
nm) as the photosensitive layer having a sensitivity to
PC), α-Si, Se-Te, etc. are known, and an organic photoconductor (OPC) is used in this embodiment. Generally, in the case of laser writing, a negative that shines light on the image area /
Positive (N / P) process and positive that shines light on the background
There are two types of positive (P / P) processes. In this embodiment, the former N / P process is adopted.

The charging charger 121 is of a scorotron type having a grit on the photoconductor side, uniformly (-) charges the surface of the photoconductor drum 111, and irradiates the image forming portion with a laser beam to change the potential of the portion. Drop it. Then, the background portion of the surface of the photoconductor drum 111 is -750 to -800.
V, the image portion has a potential of about -500 V, and an electrostatic latent image is formed on the surface of the photosensitive drum 111. This is applied to the developing roller by the developing units 122a and 122b from -500 to -60.
A bias voltage of 0 V is applied to attach (-) charged toner to visualize the electrostatic latent image.

[Developing Section] In the color copying apparatus of this embodiment, as shown in the drawing, a main developing device 122a and a sub developing device 122b.
It is equipped with two developing devices. In the case of a single black color, the sub-developing device 122b and the toner replenishing device 123b are removed. In this embodiment having two developing devices, black toner is put in the toner replenishing device 123a which is paired with the main developing device 122a, and color toner is put in the toner replenishing device 123b which is paired with the sub developing device 122b. During color development, the development is selectively performed by changing the main pole position of the multicolor developing device.

This development is performed by the color filter 107 of the scanner.
It becomes possible to perform multi-function color copying and color editing in combination with the reading of color information by switching between, the multiple transfer of paper transport system, and the double-sided copying function. For developing three or more colors, a method of arranging three or more developing devices around the photosensitive drum 111,
There is a revolver system in which three or more developing devices are rotated and switched.

The image visualized by the developing devices 122a and 122b is transferred onto the recording paper, which has been synchronized and sent to the photoconductor drum 111, from the back surface of the paper by being charged with (+) by the transfer charger 123. To be done. The transferred recording paper is subjected to AC neutralization by a separation charger 124 which is integrally held with the transfer charger 123, and the photosensitive drum 1
Separated from 11.

On the other hand, the toner remaining on the photosensitive drum 111 without being transferred onto the recording paper is cleaned by the cleaning blade 12.
It is scraped off from the photosensitive drum 111 by 5 and collected by the attached tongue 126. Further, the photosensitive drum 111
The potential pattern remaining in the area is erased by irradiating the static elimination lamp 127 with light.

[Sheet Feeder] In the present embodiment, a plurality of cassettes 128a, 128b, 128c are provided, and the recording paper which has been transferred once is passed through the re-feeding loop 129 to enable double-sided copying or re-feeding. ing.

A plurality of cassettes 128a, 128b, 12
When one of the cassettes 8c is selected and then a predetermined start button is pressed, the paper feed rollers (130a, 130b, 130c) near the selected cassette
Is rotated and is fed until the leading edge of the recording paper hits the registration roller 131. At this time, the registration roller 131
Is stopped, the rotation is started at the timing of the image position formed on the photosensitive drum 111, and the recording paper is fed to the periphery of the photosensitive drum 111. After that, the toner image on the recording paper is transferred at the transfer unit, and the separation / conveyance unit 132
The toner image transferred by suction is fixed on the recording paper by a fixing roller composed of a pair of heat roller 133 and pressure roller 134. Further, 165 is a paper leading edge detection sensor which is provided immediately in front of the registration roller 139 and detects the leading edge of the recording paper.

The recording paper transferred in this way is guided to the paper exit on the sorter 300 side (see FIG. 1) by the switching claw 135 during normal copying. On the other hand, during multiple copy,
The direction is not changed by the switching claws 136 and 137, passes through the lower sheet re-feeding loop 129, and is guided to the registration roller 131 again.

When performing double-sided copying, the copying machine body 10
There are two cases, that is, the case of performing only 0, and the case of using the double-sided reversing unit 400 (see FIG. 1). Here, the former case will be described. The recording paper guided downward by the switching claw 135 is further guided downward by the switching claw 136, and then sent by the switching claw 137 to a tray (not shown) further below the re-feeding loop 129. By reversing the roller 138, it is fed again in the opposite direction, and by switching the switching claw 137, it is guided to the sheet refeeding loop 129 and fed to the registration roller 131.

[ADF] FIG. 4 shows the configuration of the ADF 200. The ADF 200 automatically guides the originals one by one onto the contact glass 106 and automatically ejects them after copying. A stack of documents (not shown) placed on the document feeding table 201 is aligned in the width direction of the documents by the side guides 202. The placed document is the paper feed roller 20.
At 3, the sheets are separated and fed one by one, and are conveyed to a predetermined position on the contact glass 106 by the rotation of the conveyor belt 204 and positioned.

When the copying of the predetermined number of sheets is completed, the original is discharged to the discharge tray 205 by the rotation of the conveyor belt 204 again. Although not described in detail, the side guide 20
By counting the position of 2 and the document feed time,
The document size is being detected.

[Sorter] FIG. 5 shows the structure of the sorter 300. The sorter 300 sorts the recording sheets discharged from the copying apparatus main body 100 into, for example, page order, page by page, or a preset bin 30.
It is a device for selectively feeding 1a to 301x. The recording paper conveyed by a plurality of rollers rotatably driven by the motor 302 is selected by changing the pawls (not shown) near the entrances of the bins 301a to 301x.
It is led to 1a-301x.

[Double-Sided Reversing Unit] FIG. 6 shows the structure of the double-sided reversing unit 400. As described above, the copying apparatus main body 100 side can only perform double-sided copying for each sheet.
By attaching the double-sided reversing unit 400, double-sided copying can be performed collectively.

When making a double-sided copy collectively for a plurality of sheets, in the copying apparatus main body 100 (see FIG. 2), the recording paper which has been fixed is transferred to the double-sided reversing unit 400 via the switching claw 135 and the switching claw 136. Sent. The recording paper that has entered the double-sided reversing unit 400 is accumulated on the tray 402 by the paper discharge roller 401. At this time, the recording paper is fed vertically and vertically by the feed roller 403 and the side alignment guide 404.
The sides are aligned. The recording sheets stacked on the tray 402 are re-fed by the re-feeding rollers 405 when back side copying is performed. At this time, the recording paper sent to the copying apparatus main body 100 side is directly guided to the refeed loop 129 by the switching claw 136 and the switching claw 137 (see FIG. 2).

FIG. 7 is a block diagram showing the main configuration of the control system of the image forming apparatus according to the present invention. In the figure, 7
Reference numeral 01 is an input means for inputting that the manuscript image is a table, and if there is a character string such as a table title or a note, the range is input by coordinates, 702 is a manuscript size detecting means for detecting the size of the manuscript, and 703 is A recording paper size detecting means for detecting the size of the recording paper set in the paper feeding portion, 704 is a display means for displaying the state of the device, warnings, operation guidance, etc., and 705 is a device for displaying the entire device based on a predetermined control program. It is a control means configured by a microcomputer system for controlling.

Further, the control unit 705 has a scanner unit 708 as an image reading unit, an image processing board 110 as an image processing unit, and an image for recognizing whether the read image data is a character or a ruled line. A recognition unit 706, a storage unit 707 that stores read image data and input data input by the input unit 701, and a writing unit 709 that is an image writing unit are connected to each other.

FIG. 8 is an explanatory view showing an example of a document according to the present invention. The operation in the above configuration will be described by way of an example of copying the document shown in FIG. In the figure, reference numeral 801 is an original, and in this case the original 80
Reference numeral 1 denotes a table image recorded in A3 size, reference numeral 802 denotes a central position of the original 801, and reference numeral 803 denotes a character string such as a title or a note added to the table.

First, the original size detecting means 702
It is detected that the original on the contact glass 106 is A3 size portrait. Next, the input means 701 designates that the image of the original 801 is a table. Further, when there is a character string 803 such as a title or a note, the range in which the character string 803 is written is designated by coordinates. Each of these designated data is stored in the storage unit 707. After that, the scanner unit 708 reads the original 801 and temporarily stores it as image data in the storage unit 707, and the image processing board 110 performs the following processing to finally output a divided image as shown in FIG. To do.
It should be noted that reference numerals 901 and 902 denote the margin boundaries of each recording sheet after division.

In this case, since the original 801 is larger than the A4 size, the central position 802 of the original 801 is
It is divided into two with the border as the boundary. At this time, the input means 701
By avoiding the range of the character string 803 designated in advance, the margin boundary 901 is moved so that the left boundary of the designated range of the character string 803 overlaps. By this image processing, the character string 803 in the designated range is moved to the central position 802.
If the area is not divided, the image is formed on the photoconductor drum 111 via the writing unit 709 as it is.

On the other hand, even if the character string is moved so that the boundary 901 of the blank space and the left boundary of the specified range of the character string 803 overlap in the original as shown in FIG. 10, the character string 803 is still in the divided portion (center position 802). ), If only the moving process of the character string 803 by the above process is performed, the central position of the document is 8
The character string 803 is divided by the part 02. In this case, after further reducing processing so that the set range falls within the A4 size, an image is formed on the photosensitive drum 111 via the writing unit 709.

Further, the above processing operation will be described in detail with reference to the flow charts shown in FIGS. First, the document size detection unit 702 detects the size of the document 801 (S1101), and sets the paper feed stage of the paper feed unit (S1102). Next, it is determined whether or not document size> recording paper size (S1103). That is, the manuscript 8
It is determined whether 01 is larger than the recording paper size. If it is determined in step S1103 that the document size is smaller than the recording paper size, normal copy processing is executed (S1104), and this processing ends.

On the other hand, in step S1103,
If it is determined that the original size is larger than the recording paper size, it is further determined whether or not the mode is the front mode (S11).
05). If it is determined that the table mode is set, that is, if the table mode is input by the input unit 701, "Specify division prohibited range" is displayed on the display unit 704 (S1106). ). afterwards,
The above division prohibition range is the start point and end point coordinates x ₁ , x ₂ , y
_When input by ₁ and y ₂ (S1107), it is determined whether the print key is ON (S1108). At this time, when it is determined that the print key is turned on, the image reading process is started by the scanner unit 708 (S1109).

Next, it is determined whether or not x ₂ (the end point of the character string 803) is longer than half the length of the original 801 (S1).
110). If it is determined in step S1110 that x ₂ is longer than half the length of the original 801,
The designated range is moved by the coordinates x ₁ ', x ₂ ', y ₁ , y ₂ (S1111). Then, the x ₂ 'is the original 801
Is longer than ½ of the length (S111)
2). In this step S1112, x ₂ 'when determines that longer than half the length of the document 801, a magnification (original length _{/ 2-x 1') /} (x 2 '-x 1' )
(S1113), the process proceeds to the process shown in FIG. 12, the designated range is reduced (S1114), the image division process is performed (S1115), and the image output is executed (S111).
6), this process ends.

On the other hand, in step S1110,
If it is determined that x ₂ is shorter than 1/2 of the length of the manuscript 801, or in step S1112,
If it is determined that x ₂ 'is shorter than 1/2 of the length of the original 801, the process proceeds to step S1115, image division processing is performed (S1115), and image output is performed (S11).
16), this processing ends.

Further, if it is determined in step S1105 that the mode is not the table mode, the process proceeds to the process shown in FIG. 13 and it is determined whether or not the print key is turned on (S1117). If it is determined that the print key is turned on, the image data is read by the scanner unit 708 (S1118), the image division process is performed (S1119), the image output is executed (S1120), and the present process is terminated. .

Next, the processing in the case of using the image recognition means 706 will be described based on the flow charts of FIGS. 14 and 15. In FIG. 14, first, the size of the document 801 is detected by the document size detection unit 702 (S140
1), the paper feed stage of the paper feed unit is set (S1402). Next, it is determined whether the print key is ON (S1).
403). At this time, if it is determined that the print key is ON, the image reading process is started by the scanner unit 708 (S1404). Then, it is determined whether or not the original size> the recording paper size (S1405). If it is determined that the original size is smaller than the recording paper size,
Normal copy processing is executed (S1406), and this processing ends.

On the other hand, in step S1405,
When it is determined that the document size is larger than the recording paper size, it is further determined whether or not the mode is the front mode (S14).
07). Here, when it is determined that the table mode is set, that is, when the table mode is input by the input unit 701, the character string outside the frame of the table is searched (S140).
8). Next, the start and end coordinates of the character string x ₁ , x ₂ ,
The range is searched by y ₁ and y ₂ (S1409),
x ₂ (the end point of the character string 803) is 1 / the length of the original 801.
It is determined whether it is longer than 2 (S1410). In step S1410, x ₂ is the length of the original 801 being 1
If it is determined that it is longer than / 2, the character string 803 is moved by the coordinates x ₁ ', x ₂ ', y ₁ , y ₂ (S14).
11).

Next, x ₂ 'is 1/2 the length of the original 801.
It is determined whether it is longer (S1412). In this step S1412, x ₂ 'is the length of the original 801 is 1
/ If it is determined from the long 2 calculates a magnification as the (original length _{/ 2-x 1 ') /} (x 2' -x 1 ') (S
1413), the processing proceeds to the processing shown in FIG.
Is reduced (S1414), and image division processing is performed (S14
15), image output is executed (S1416), and this processing ends.

In step S1407,
When it is determined that the mode is not the table mode, the above step S14
10, it is determined that x ₂ is shorter than 1/2 of the length of the manuscript 801, or the above step S1412.
When it is determined that x ₂ 'is shorter than ½ of the length of the document 801, the process proceeds to the process shown in FIG. 15, the image division process is performed (S1415), and the image output is executed (S1416). ), And ends this processing.

In addition, the image recognition means 706 executes ruled line determination to recognize image data outside the outer frame of the table, and makes the recognized data into information in which division is inappropriate. This is because the information located outside the table frame can be generally judged to be the title, cautionary note, etc. for the table, and can be regarded as information not suitable for the division processing.

Next, the effect of the above embodiment will be described. First, when it is detected that the original size is larger than the recording paper size, the original image is divided and copied onto the recording paper, so that it is possible to unify various-sized originals into recording papers of a predetermined size.

Secondly, at the time of the above division, the character strings such as titles and notes added to the table are moved without being divided, so that the relevance of the image data can be maintained. it can.

Thirdly, at the time of the above division, the image data in the designated range of the character string such as a title or a note is reduced, so that the character string is not further divided and the relation of the original image is eliminated. The sex can be retained more.

Fourthly, since the range of information in which the title, the note, etc. in the image data are improperly divided is designated by the coordinate, the range of the information can be more surely specified.

Fifth, since the information outside the outer frame of the front image is recognized as the inappropriate division information, the inappropriate division information can be recognized quickly.

In this embodiment, the image forming apparatus has been described by taking a digital copying machine as an example. However, the same processing can be applied not only to the digital copying machine but also to the image output of a laser printer or a facsimile machine. it can.
For example, when only A4 size recording paper is accommodated in the apparatus, or when A4 size or larger recording paper cannot be used, or when image data of A4 size or larger is input online or offline, as in this embodiment, ，
The image may be output in two pages.

By the way, as a document placing system of the copying machine,
There are two methods, a center reference method in which an original is distributed to the center of the contact glass 106 and a corner reference method in which the front side of the contact glass 106 is used as a reference. In the present embodiment, the case of the corner reference method has been described as an example, but the center reference method can be similarly applied.

Further, in the present embodiment, the image of the entire original is read at once, and the read image data is accumulated in the storage means 707 and image processing is performed.
The same process may be executed by reading the left page and then reading the right page in two steps.

As described above, according to the image forming apparatus of the present invention, the document image is a front image by the input means, and the division of the titles, cautions, etc. added to the table is inappropriate. Input a range of information, the image recognition means recognizes whether the image data is a character or a ruled line, stores the input data and the image data read by the document reading means in the storage means, and the image processing means When the document size is larger than the recording paper size, the image data is divided into image data. At this time, the division is added to the table based on the data input by the input means and the judgment of the image recognition means. If the inappropriate information is in the division position, the document of a predetermined size is divided into two parts on a recording paper of a predetermined size in order to selectively execute the reduction process or the movement process. In the time of the table image division such as the title and notice had an incorrect string if the document, it is possible to obtain a good image without impairing the relevance of the other.
