Description

Description: BACKGROUND OF THE INVENTION (Industrial application field) The present invention relates to a copying apparatus, and more particularly, to a digital system capable of correcting a predetermined type of image information contained in a read original and performing clear recording. Related to a copying apparatus.

(Prior Art) Generally, as a function of copying and recording document information of a manuscript,
Copiers have become widespread.

In addition, digital copying apparatuses have been developed to meet the recent demand for downsizing and personalization of apparatuses. This copying apparatus generally includes a reading unit, a control unit, a driving unit, and a recording unit. The reading unit uses, for example, a line image sensor, performs main scanning for one line in the width direction (row direction) of the document, photoelectrically converts document image information of the document, and outputs the image information to the control unit as an image signal. The reading unit performs sub-scanning at a predetermined speed (or pitch) every time one line of main scanning is performed by a driving unit.
Reads the entire document information. The sub-scanning is set in advance to the maximum readable document size. The control unit outputs a control signal to the drive unit based on a command from an operation unit (not shown), and also processes an image signal input from the reading unit and outputs the processed image signal to the recording unit. The driving unit drives the sub-scanning of the reading unit and the movement of the recording paper supplied to the recording unit in the sub-scanning direction at a predetermined timing in synchronization with each other based on a control signal from the control unit. The recording unit uses, for example, a thermal head, and selectively generates heat on a line-by-line basis based on an image signal input from the control unit to color a roll-shaped thermosensitive recording paper stored in the apparatus. A sub-scan is performed for each line, and a written image similar to the original is recorded at a predetermined size.

(Problems to be Solved by the Invention) However, in such a conventional copying apparatus, the reproducibility of a recorded image depends on the assembling accuracy of the reading unit, the reading position accuracy, and the like (hereinafter referred to as the reading unit accuracy). The recorded image is affected depending on the accuracy of the reading unit. If the image information of the original to be copied is a picture or a character, there is no problem visually, but OCR (Optical Character Reader) characters,
When image information requiring display accuracy, such as an OMR (Optical Mark Reader) mark and a bar code, is included, the reproducibility of the recorded image becomes a problem.

That is, if the accuracy of the reading unit is low, the image quality of the recorded image deteriorates, and the reproducibility of the image information requiring the above-described display accuracy deteriorates. However, there is a problem in that a reading error occurs even if an attempt is made to read the information, and it becomes impossible to read accurate information.

(Object of the Invention) Accordingly, the present invention stores a predetermined area in image information of a document read by an image reading unit in a first storage unit, and stores a specific area in the image information stored in the first storage unit. Referring to the image information stored in advance in the second storage unit, and replacing the image information stored in the first storage unit with the image information stored in the second storage unit if the same image information exists; Accordingly, an object of the present invention is to correct image information in a specific area of a document irrespective of the accuracy of the image reading unit, and to improve the reproducibility of image information requiring accuracy.

(Constitution of the Invention) In order to achieve the above object, the present invention provides an image reading unit that reads image information of a document, photoelectrically converts the image information, and outputs the image information. An image recording unit that records an image on a recording sheet, and a control unit that integrally controls the entire apparatus. The control unit includes an image of a predetermined area in the image information of the document read by the image reading unit. A first storage unit for storing information, and a second storage unit in which predetermined image information is stored in advance, wherein the control unit stores the image information in a predetermined area of the document stored in the first storage unit. Comparing the image information with the predetermined image information stored in the second storage means, when it is determined that the image information is the same, the image information existing in a specific area of the image information stored in the first storage means is stored in the second storage means. After replacing the image information with the predetermined image information stored in the storage means, The image information stored in the storage unit is output to the image recording unit.

 Next, the operation will be described.

Here, the operation of the copying apparatus 11 of the present invention differs depending on the switch position of the mode changeover switch 60 provided on the operation unit 16. Therefore, each operation will be described sequentially.

In this embodiment, a case where a document 26 as shown in FIG. 5 is copied will be described.

(I) Copying in the normal mode.

First, as described above, the copying apparatus 11 is set on the document 26, and when the start switch 59 of the operation unit 16 is pressed, the control unit 13 is pressed.
Outputs a control signal to each section. At this time, the LED array provided in the image reading means 18 is turned on, the surface of the document 26 is illuminated, and the line image sensor performs main scanning for each line from the top of the document 26 for reading. The read image is photoelectrically converted, digitally processed as an image signal by the scanner I / F 32 of the control unit 13 via the buffer amplifier 21, and output to the recording unit 38 of the printer unit 14 together with the control signal via the printer I / F 34. Is done. Based on this image signal, the heating element of the recording means 38 selectively generates heat, and
41 is colored and recording for one line is performed. On the other hand, when reading of one line by the image reading means 18 is completed,
A sub-scanning signal is output from the control unit 13 to the sub-scanning unit 19, and the sub-scanning unit 19 performs sub-scanning to the next line position. A drive signal is output from the control means 13 to the transport means 40 in synchronization with the sub-scanning signal, and the drive motor of the transport means 40
The roll 43 rotates, and the roll paper 41 supplied between the platen roller 42 and the recording means 38 is transported to the next line position.

As described above, the recording is performed line by line by the printer unit 14 in synchronization with the reading timing of the line unit by the scanner unit 12 according to the control signal from the control unit 13. Therefore, as shown in FIG. 6, the same image as that of the document 26 is formed on the roll paper 41 and discharged from the paper discharge port 56. However,
In the case where image data requiring display accuracy such as a bar code is contained in the original document 26 (see FIG. 5), if the accuracy of the image reading means 18 is low as described above, the reproducibility of the bar code in the recorded image deteriorates. As a result, the information indicated by the barcode cannot be accurately read by a reading device such as a barcode reader.

Therefore, when copying the original 26 including image information that requires reproducibility, such as a bar code, the mode switch 60 provided on the operation unit 15 is switched to the correction mode to perform copying.

(II) When copying in correction mode.

First, the operation in the correction mode In the region of a ₁ in the reading range of the image reading unit 18 shown in FIG. 7,
As in (I), the reading of the document 26 by the image reading means 18 and the recording on the roll paper 41 by the recording means 38 are performed synchronously at a predetermined timing, but the reading position of the image reading means 18 is the seventh position. When the area exceeds a _{1 in} the figure, the recording means 38
1 for each line recorded by, and the transport of the roll paper 41 is stopped by the conveyance means 40, only read is performed for the region of Figure 7 in a _2. That is, the read seventh
Figure a ₂ areas of image information buffer amplifier 21 for each line
, And are digitally processed by the scanner I / F 32 of the control means 13 and sequentially stored in the RAM 37. Then, the image information (actually, a pattern such as a bar code as described above) in the a ₂ × b ₂ area included in the image information of the area a ₂ in FIG. If the same image information exists in the ROM 36 by comparing and referring to image information stored in advance (this image information is also a pattern such as a bar code as described above), the image information stored in the RAM 37 is stored in the RAM 37. The image information referred to by the ROM 36 is transferred to the area of a ₂ × b ₂ and replaced with the existing image information. Therefore, although the image information in the a ₂ × b ₂ area stored in the RAM 37 is the same as that of the original 26,
Corrected to the correct image information stored in the ROM 36.

Image information of FIG. 7 in a ₂ areas correction is stored in the finished RAM37 is output to the printer I / F 34 for each line, the has been completed or the recording paper roll 41 a by the recording means 38 7 sequentially recorded from the subsequent positions in the region of the figure a _1. Therefore, the barcode included in the copy image has high reproducibility as shown in FIG. 8, and accurate information can be read by a reading device such as a barcode reader. Incidentally, the a ₁ region in the reading range of the seventh image reading unit 18 shown in FIG., A ₂ region and a ₂ × b ₂ regions which can be arbitrarily set by the specification (format), etc. of the document 26 Needless to say. The setting of this area can be performed, for example, by a command from an external device (such as a personal computer) connected via the external I / F 16.

Next, the above operation will be described based on a flowchart.

FIG. 9 is a flowchart of a program showing the operation of the copying apparatus according to the present embodiment. This program is executed, for example, when the start switch 59 is pressed while the mode changeover switch 60 of the operation unit 15 is on the correction side.

First, the first document 26 by the image reading unit 18 in step P ₁
At the same time as reading the lines, the sub-scanning unit 19 sub-scans the image reading unit 18 for one line. At this time,
The image signal for one line read from the image reading means 18 is held in the buffer amplifier 21.

Then, the image reading unit 18 determines whether or not the region of a ₁ in step P _2. This is, for example, the image reading means 18
And the amount of movement is detected by a sensor or the like, or the amount of sub-scanning of the image reading means 18 is counted for each line. When the image reading unit 18 is determined to be within the scope of a _1, held in the buffer amplifier 21 in Step P ₃ 1
Transfer the image signal for the line to the scanner I / F32, and
Performs one line recorded by the recording means 38 in ₄ repeatedly executes the same processing returns to the step P ₁ after sub scanning the roll paper 41 to the next line position by the conveying means 40. Thus, while the image reading unit 18 is within the area of a ₁ is conventional and the reading of the document 26 by the image reading unit 18 similarly, the recording of the roll paper 41 by the recording unit 38 in synchronization with each line Done.

On the other hand, when the image reading unit 18 in the step P ₂ exceeds the area of a ₁ transfers one image signal lines stored in the buffer amplifier 21 proceeds to step P ₄ to RAM37 of the control means 13, stores I do. In this case, the control to the recording unit 38 is stopped, the roll paper 41 is held in position terminates the recording of the last line of the region of a _1. Then, the image reading unit 18 determines whether it has finished reading the area of a ₂ in Step P _5. This in image reading and the step P ₂ means 18
Is detected by a sensor or the like, or the sub-scanning amount of the image reading means 18 is counted for each line. If it is determined to have ended the reading of a ₂ region, reads the image information of a ₂ × b ₂ in area included in the area of a ₂ in Step P ₆ (for example, a bar code or the like, a predetermined image information).

On the other hand, if the reading of the area of a ₂ in the step P ₅ is not completed, read the area of a ₂ repeatedly executes the processing returns to the step P _1.

Then, image information the same image information and read a ₂ × b ₂ region in step P ₇ to check whether there in ROM 36. If it is determined that the image information the same image information and a ₂ × b ₂ region is within ROM 36, RAM the image information in the ROM 36 in step P ₈
Transfer to 37, as well as substituted, and outputs the image information stored area of a ₂ was the RAM37 in step P ₉ to the printer I / F 34.

Then, the recording of the region of a ₂ in Step P _10. This is based on the image information and the sub signal of a ₂ regions from the printer I / F 34, made by the sub-scanning of the roll paper 41 by one line recording and the transfer mechanism 49 by the recording unit 88, also a recording the _second area is performed sequentially from the last line position of the a ₁ region.

On the other hand, the in the absence image information the same image information and a ₂ × b ₂ region in the ROM36 in step P _7, an alarm display proceeds to step P _11. The alarm causes the user to recognize that the image information is not corrected, for example, by turning on a display lamp or a buzzer sound.

Then executes the processing of the step P ₉ or later. Therefore, the recorded image at this time is the same as that obtained when (I) copying is performed in the normal mode.

By operating the mode changeover switch 60 of the operation unit 15 in this manner, OCR (Optical Character Reader) characters and OMR (Optical
Even if image information such as a mark reader and a bar code is included, the reproducibility of the image information requiring such display accuracy can be improved regardless of the accuracy of the image reading means 18. As a result, the image information requiring the display accuracy in the recorded image can be accurately read by a predetermined reading device.

In this embodiment, the copying apparatus 11 using a line image sensor as the image reading unit 18 of the scanner unit 12 and using a thermal head as the recording unit 38 of the printer unit 14 has been described. Not limited to
That is, it goes without saying that the present invention can be applied to any digital copying apparatus.

Further, in the present embodiment, the case where the image information included in the specific area of the document 26 is corrected has been described, but the invention is not limited to such a sun. For example, the mode switch 60 of the operation unit 15
By providing an image information addition mode for the image data, it is also possible to add image information that is not stored in the original document 26 and stored in the ROM 36 in advance to the recorded image.

(Effect) According to the present invention, when copying an original, image information in a specific area of the original can be corrected regardless of the accuracy of the image reading unit, and the reproducibility of image information requiring accuracy after recording is improved. Can be done.
