Description

[Detailed Description of the Invention] [Industrial Application Field] This invention reads a pattern image in which the operation modes such as magnification, cassette size, density, etc. necessary for image formation are converted into a predetermined pattern, and automatically sets the operation mode. The present invention relates to an image processing device.

[Prior art and its problems]

Conventionally, the operation mode of this type of image processing apparatus has been configured so that it can be set by manually operating keys or levers on the operation board, and the operator can change the operation mode each time depending on the document. It was set.

Previously, all you had to do was set the number of copies and start copying, but now the operability has improved, allowing you to select the paper size, set the magnification, and set the image density.

Sorter operation designation 1 Operation has become complicated because functions such as double-sided copy designation have been expanded.

In addition, recent features include a variable magnification function, 9 image reversal functions, 9 editing functions,
Some cameras have a moving function, a special magnification change function, an image quality processing function, etc., and more and more other functions are being developed.Hereinafter, each of the two functions will be briefly explained.

The variable magnification function is equal magnification (100% magnification), fixed magnification (specified size), stepless variable magnification (specified magnification 50-200%),
There are xy variable magnification (independent variable magnification in main and sub-scanning directions), etc.

The image reversal function includes an original image, a negative/positive reversal image, etc.

Editing functions include no editing, white masking, and black masking. Additionally, there are white frame trimming, black frame trimming, automatic document position detection, etc.

The movement functions include moving, specifying the destination, and moving the origin (
cornering) and centering.

Special magnification functions include no special magnification specification, automatic magnification,
There are XY magnification auto, etc.

Image quality processing functions include automatic exposure (AE), halftone processing, and the like.

In devices with the above functions, the operator inevitably has to set each mode many times on the operation board.
It takes time and effort, and can lead to mistakes in settings. In addition, it takes more effort and time to change the operation mode once it has been set. Therefore, in order to solve these problems, preset keys are provided on the operation board to change the frequently used mode. It is configured so that it can be used at any time. However, since the number of preset keys is limited, there are some operation modes that cannot be preset.

In addition, there are devices that can store preset operation modes in a non-volatile RAM cartridge and call them up at any time to set the operation mode, but the device is expensive and the writing/reading of RAM contents cannot be done manually. It is inconvenient to use because the operator must use the operation board to perform the operation.

Furthermore, there are devices that store the operation mode on a magnetic card, but the device becomes expensive and a drive device is required to read and write the operation mode on the magnetic card, making the device large. There were many drawbacks such as.

[Purpose of the invention]

This invention was made in order to eliminate the above-mentioned drawbacks, and it converts the operation mode such as magnification, cassette size, density, etc. required for image formation into a predetermined pattern, optically scans the pattern image, and converts it into an electrical signal. An object of the present invention is to provide an image processing device that automatically sets an operation mode by decoding a pattern image signal. Examples of the present invention will be described below.

Next, the operation of the reader 1 will be explained.

The original is placed face down on the original platen glass 12.

Its placement reference is on the back left side when viewed from the front, and is pressed onto the document table glass 12 by the document cover 11. The document is illuminated by the fluorescent lamp 13, and an optical path is formed such that the reflected light is focused on the surface of the light receiving element group 16 via the mirror 14, 17 and the lens 15. The mirror 14 and the mirror 17 are configured to move at a relative speed of 2:1. The optical unit composed of the above 11 to 17 is operated by a DC servo motor.
Move from left to right at a constant speed while applying L control. This moving speed is 180mm/
sec, and on the return trip it is 468 ram/sec. The resolution in this sub-scanning direction is 161 ines/m+e. The document sizes that can be processed range from A5 to A3.
The orientation of originals is A5 and A4.

Next, the operation of the printer 2 will be explained.

The image signal processed by the reader 1 and made into bit serial is input to the laser scanning optical system unit 18 of the printer 2. The image signal from the reader 1 is applied to a semiconductor laser and undergoes electrical-to-optical conversion, and the diverging laser light is converted into parallel light by a collimator lens, and then converted to a higher speed (260 Orpm).
The laser beam is irradiated onto a rotating polyhedral mirror, and the photoreceptor 19 is scanned with the laser beam with a scanning width of approximately 400 layers. The effective image at this time is 297 mm in horizontal size of A4 paper. Therefore, the signal frequency applied to the semiconductor laser at this time is approximately 20KH.
z (NR2).

The speed of the photoreceptor 20 and the conveyance system is 180 tracks/sea, which is the same as the forward path of the reader. Therefore, the copy speed when making copies using reader 1 and printer 2 is A4.
That's 30 sheets/minute. Further, the printer 2 uses a separation belt on the front side to separate the transfer paper that is in close contact with the photoreceptor 20, but because of this, an image corresponding to the width of the belt is missing. If a signal is placed on this belt width,
Toner adheres to the separation belt and stains the subsequent transfer paper, so the video electrical signal corresponding to the width of the separation belt 8-■ is cut in advance on the reader 1 side. Furthermore, if toner adheres to the leading edge of the transfer paper, it will wrap around the fixing roller during fusing and cause a jam, so the video electrical signal corresponding to the 2s + s width of the leading edge of the transfer paper is cut in advance on the reader 1 side. ing.

Next, the mutual relationship between the reader 1 and printer 2 will be explained.

The image processing device of the present invention can convert image information into electrical signals as described above, and furthermore, since the reader 1 and the printer 2 are separated and have independent functions, image information cannot be transmitted between them. It can be carried out. Therefore, when the reader 1 and the printer 2 are set, or when only the reader 1 is set alone, mutual communication can be performed by attaching a communication module to the reader 1 side. Further, when the printer 2 is set alone, local communication within the premises can be performed by attaching a communication module to the printer 2 side and connecting these units in a loop. Furthermore, by arranging a gateway (an interface between a public line and a local network) on the loop, it becomes possible to communicate with outside the premises. Furthermore, an e-mail system can be configured between the head office building and the branch office building, which connect the network and the copying device unit.

Next, the functions possessed by the image processing apparatus of the present invention will be explained.

In addition to a simple copying function, the image processing device of the present invention has a variable magnification function that allows arbitrary enlargement/reduction, an editing function that allows you to extract or delete any part of a document, and an automatic adjustment function that automatically adjusts the size and position of the document. It has various functions such as automatically detecting the image size and automatically changing the size and editing. The functions for manipulating images on a document in this way are collectively referred to as image manipulation functions.

In addition to making a copy of the original image read by the connected printer 2, the 1 communication control unit (Common
The document image can be sent to another printer 2 via the printer 2 (control unit).

Further, it is also possible to receive a document image sent from another reader 1 to the printer 2 at hand. These functions are collectively called an image transfer function. Furthermore, the above-mentioned selected functions can be arbitrarily registered in the six preset keys. Security details can be specified by the user and are retained even when the power is turned off. These functions are collectively referred to as preset functions. It also has an automatic exposure function that removes the background of documents, and a function that outputs images with gradations such as photographs with good reproduction. These functions are collectively referred to as image quality processing functions. To summarize, there are the following five image quality control functions.

The variable magnification functions include equal magnification (100%), fixed magnification (specified size), stepless variable magnification (specified magnification of 50 to 200%), and xy variable magnification (independent variable magnification in the main and sub-scanning directions).

The image reversal function includes an original image, and a negative/positive reversal image.

Editing functions include no editing, self-masking, and black masking. However, the latter two automatically switch to XY auto magnification, and other magnification functions cannot be specified. There are also white frame trimming, black frame trimming, and automatic document position detection. However, here, the 9 magnification functions, inversion, movement, and special magnification functions are linked.

The movement functions include no movement, destination specification, origin movement (cornering), and centering.

No special variable magnification function specified, variable magnification O)
, XY magnification auto. However, the latter two cannot specify other scaling functions. The movement function and special magnification change function are
Only valid when editing functions such as white/black trimming and automatic document position detection are specified.

Also, the preset functions include registration (memorize in the preset key) and readout (read out the stored contents of the preset key). Note that some preset keys also have a reset function to return to standard mode.

Furthermore, the image quality processing functions include automatic exposure (AE) and intermediate processing.

Next, the operation will be explained.

A document is placed on document table glass 12, and a reflected image is formed on light receiving element group 16 via lens 15 and converted into an electrical signal. The converted image signal is amplified by an amplifier 82 and then converted to a digital signal by an A/D converter 83.
Furthermore, an image operation function 2 image transfer function is performed by the processing circuit 92 according to the operation mode set by the operator on the operation board 1a.

It performs image quality processing functions and outputs an image signal.

To automatically set the operation mode, first press the key 57. By pressing this button, the pattern document recognition mode is set in the reader 1.Next, the pattern image is placed at a predetermined position on the document platen glass 12, and the copy key 42 is pressed. This press causes the optical system unit to start a normal scanning operation, and as described above, a reflected image is formed on the light receiving element group 16 via the lens 15 and converted into an electrical signal. The converted image signal is amplified by an amplifier 82, and then
The signal is converted into a digital signal by the /D converter 83 and input to the pattern recognition circuit 90. The pattern recognition circuit 90 analyzes the pattern image signal, and the operation mode setting means 84a sets the operation mode according to the received pattern image.

After completing the settings, when the operator presses the copy key 42, a transfer operation according to the operation mode is started.

FIG. 4 is a configuration diagram of a pattern image document showing an example of a pattern image document according to the present invention.The document size is A4, and the document is set on the document table glass 12 with its longitudinal direction aligned with the operating direction.

Next, the structure of the pattern image document will be explained. The pattern document has a 5mm x 10mm black line starting from the left, ,
5mm x 10m+o white line, 5+wm x 10mm
The black line is marked in advance. This is the start code. #i! and place a 10mm wide white part,
The operation mode is patterned using a mode pattern composed of 23 bits in which 23 mode patterns of 10Lm×10+am are lined up. After this, place a white part with a width of 10+w+a, and a black line of 5mm x 10m+s.

5+amX10mm+ white silver, 5+1thX l O
mm black line, 5mm x 10mm white line, 5+++ Otori XL
A black line of 0 mm is marked. This represents the end code, and is written in advance like the start code. Further, next to the mode pattern of the l line, an inside having a width of 10 mm is placed in the sub-scanning direction, and the next mode pattern line is configured in the same manner as described above. Note that a 20 mm wide white area is placed at the top of the pattern original in the sub-scanning direction, and below, a lo+a+a-wide mode pattern line and a 10 mm wide white area are alternately repeated in the sub-scanning direction, forming one pattern original. Up to nine mode pattern lines can be written on the screen. Therefore, a maximum of 23×9=207 bits of information can be input. In addition to the above, mode patterns to be used include (2aut of 5) and (code 3
9) etc. can also be used.

Next, the recognition operation of a pattern image document will be explained with reference to the flowchart of FIG. In addition, 5L-3
13 represents each step.

First, it is determined whether the key 57 is pressed or not.
), in the case of YtS, the reader 1 is set to pattern image recognition mode (S2). Next, the operator sets the pattern original on the original platen glass 12 and waits for pressing the copy key 42 in step S3. ), the optical system unit of the reader 1 starts scanning and reads the pattern image original (34). If the answer is No, the start code is written down, and if the answer is YES, the read pattern image signal is sent to the amplifier 82. The pattern image signal is input to the pattern recognition circuit 90 via the A/D converter 83 and analyzed (S6), and then the end code read on the pattern document read in step S4 is judged (S7). In this case, the process returns to step S6, and if the end code is read, the pattern image information written in that line analyzed in step S6 is stored in the RAM 86.
C, SB). Next, it is determined whether the scanning of the optical system unit is completed (S9), and if the answer is No, the operations from step S55 to step S9 are repeated, and if the answer is YES, the process is performed in step S8.
Then, the operation mode setting means 84a sets the operation mode based on the pattern document information stored in the RAM 86 (S l O).

Next, the key 57 is reset (S l l), the copy key 42 is waited for to be pressed (S12), and if pressed, the copy operation is started in the scanning mode set in step Slo (313), and the control end.

Incidentally, if either the start code or the end code is not read in steps S5 to S7, the image information obtained during that time is determined not to be pattern image information and is canceled. This eliminates pattern reading errors. Furthermore, since the optical system unit scans regardless of the presence or absence of a pattern, the end code determination loop will not be missed in the start code determination loop.

FIG. 6 is a diagram explaining the copying operation according to the present invention.
00 is an original to be copied in the first mode, 101 is an original to be copied in the second mode, and 102 is an original to be copied in the third mode. Note that the operator sets a pattern image document corresponding to each mode at the beginning of each document.

Next, the operation will be explained.

First, an operator organizes the originals 100, 101, and 102 according to each mode, and sets a desired pattern original at the beginning of each original. Since this operation is performed by the operator on the desk, setting errors can be avoided.
Set the pattern image original at the beginning of the original 100 on top, press the key 57 and the copy key 42 in this order,
After reading the pattern image original, the key 57 is reset. This operation automatically sets the operation mode. Next, until the original 100 is finished, the original platen glass 1 is
2 and press the copy key 42. Repeat this operation until the pattern image original that specifies the second mode appears. Then, read the pattern image original that specifies the second mode in the same manner as described above, and read the original in the automatically set second mode. 101 is executed. Manuscript 1
The same applies to 02. In this way, the operator does not need to set the operation mode for each document, eliminating setting errors.

FIG. 7 is an internal sectional view of an image processing apparatus showing another embodiment of the present invention, 11 to 17 and 19 to 35 are the same as in FIG. 1(b), 36 is the main body of the apparatus, A reader 1 and a printer 2 are integrated.

Next, the operation will be explained.

First, a pattern image manuscript for which the operator specifies the operation mode is created on pattern image manuscript paper according to each manuscript, and this is placed at the beginning of the pre-sorted manuscripts.
This operation completes the copy preparation. Next, the pattern image reading operation is started, and the pattern image original placed at the beginning of the original is set on the original table glass 12, and the key 57 is pressed to set the pattern image recognition mode. Next, when the copy key 42 is pressed, the mirror 19 is pressed to execute the pattern document reading operation.
moves upward, and then, when the optical system unit starts scanning, the reflected light from the document does not form an image on the photoreceptor 20, but is focused on the light receiving element group 16, and is converted into a pattern image signal. The pattern image is read into a pattern recognition circuit 90 and decoded. At this time, if the read original is recognized as pattern image information, the operation mode before scanning is reset, and the operation mode setting means 84a sets the operation mode specified for the pattern image original. Thereafter, the original is placed on the original platen glass 12 and a normal copying operation is performed. On the other hand, if it is recognized that the document is not pattern image information, the copy key 42 is waited for to be pressed without changing the operation mode before scanning, and when the copy key 42 is pressed, the mirror 19 is turned in the direction of the arrow. A reflected image of the original via the mirror 17 and lens 15 is directly projected onto the photoreceptor 20 to perform copying. In this way, the operation mode can be easily designated by the pattern written on the pattern image document paper.

The codes to be used include UPCA code and JAN code.
There are multi-level barcodes such as codes, and by assigning these to each operation mode and printing each created operation mode on tack paper or instant lettering (product name), pattern image originals can be easily created. can do. Further, when creating a copy of a pattern image document once created, it can be easily obtained by resetting the key 57 and pressing the copy key 42.
