DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document image input device for an electronic filing system that files document images page by page.

[Background Art] In recent years, electronic filing systems have been constructed for the purpose of saving office space and paper, and improving the efficiency of filing and searching documents.

This electronic filing system reads images of documents to be filed and stores them in a large-capacity storage device such as an optical disk device so that information can be searched page by page.

In addition, in order to be able to read and input a large number of sheet originals continuously, the original image input device for reading the original image has
An automatic document conveyance device is attached that separates documents one by one and conveys them to a reading position.

[Problems to be Solved by the Invention] However, such conventional devices have the following disadvantages.

In other words, when a large number of documents are read and input in succession, if a misfeed occurs in the automatic document feeder, the document will be read in two sheets, so the image of the document on the top of the two sheets will be A situation arises in which the data is not read and input.

At this time, the operator selects the document whose image has been scanned and
Since it is difficult to distinguish from other originals, and originals that have been determined to have been scanned are discarded, originals whose images have not yet been scanned are also discarded along with originals whose images have been scanned, and as a result, the image cannot be read. Image information of a manuscript that has not been registered is not registered in the electronic filing system, resulting in the inconvenience that the manuscript cannot be searched at a later date.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a document image input device that eliminates the disadvantages of the conventional device and allows reliable reading and input of a document.

[Means for Solving the Problems] The present invention provides an identification information generating means for generating identification information for identifying each page of a read document image.

The apparatus is equipped with a printing means for printing the identification information generated by the identification information generating means on the original document that has been read. Also,
The apparatus is equipped with an identification information generating means for generating identification information for identifying each page of a read original image, and a printing means for printing the identification information generated by the identification information generating means on the original before reading the image.

[Function] Therefore, since the identification information is printed on the original that has been read, it is possible to reliably identify the original that has not been read, and it is possible to prevent the image of the original from being omitted from being read. In addition, the printed identification information will also be read and input, so you can use it at a later date.
It is also possible to determine whether there is any leakage in the image-read document on the electronic filing system.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows an electronic filing system according to an embodiment of the present invention.

It consists of a screen instruction device PD for indicating an arbitrary point on the display screen and performing other operations.

FIG. 2 shows an example of the optical system of the scanner SCN.

In the figure, this scanner SCN has two operation modes: a sheet transport mode in which the optical system is fixed and the original is transported and its image is read, and a sheet fixed mode in which the original is fixed and the optical system is moved. .

Contact glass 1 is for holding the reading surface of a document flat, and is set to be longer in the longitudinal direction than the maximum reading size of this scanner SCN.

The light source 2 illuminates the reading surface of the document on the reading line, and the reflected light from the surface illuminated by the light source 2 is
Mirror 3. The light is guided to the lens 6 through the lens 4.5, focused by the lens 6, and imaged onto the line image sensor 7.

Also, light source 2, and 13, 4 . ．． 5 is mounted on a traveling body (not shown) that is movable in the sub-scanning direction (longitudinal direction of the contact glass 1) and is moved in the sub-scanning direction.

The upper surface of the pressure plate 8 for pressing the original against the contact glass 1 is configured as an original table 9 on which the original is placed.

The document placed on the document table 9 is transferred to the feed roller 10,
11, the document is separated one by one and sent to a conveyance roller 12, and conveyed sequentially to the reading position by conveyance rollers 12, 13 and conveyance roller 14. After passing the reading position, the document is discharged by conveyance rollers 15 and 16. .

Further, a microprinter 17 is disposed immediately before the conveyance roller 16 at the ejection position for printing identification information on the image surface of the document to indicate that image reading has been completed. A pressure plate 18 for pressing the image surface of the document against the printing section of the microprinter 17 is disposed above the printing position.

Further, the document sensor 19 is for detecting that a document is placed on the document table 9, and the document sensor 20 is for detecting that a document is placed on the document table 9.
is for detecting a document at a position immediately before the reading position, and the document sensor 21 is for detecting a document at a position immediately before the printing position of the microprinter 17.

Further, the surface of the conveyance roller 14 located immediately in front of the reading position is formed in white, and constitutes a reference white image for the shading correction function that corrects variations in the level of the read image signal. .

When reading a document image using the sheet conveyance mode, the feed rollers 10 and 11 feed one sheet of the document placed on the document table 9 in the reading direction.
2 and conveyance rollers 13 to the reading position, and the leading edge thereof is detected by the document sensor 20.

On the other hand, the traveling body is moving so that the reading position of the optical system is directly below the conveyance roller 14, and the reference white image on the surface of the conveyance roller 14 is read, and the reading position for the shading correction function is read. Reference data is sampled.

When the leading edge of the document is detected by the document sensor 20, the traveling body
The optical system moves so that the reading position of the optical system coincides with a predetermined position set on the contact glass 1 on the downstream side of the conveyance roller 14, and maintains that position.

Then, at the timing when the leading edge of the document reaches the reading position, the line image sensor 7 performs a reading operation in synchronization with the document transport.

When the reading of the image for one page of the document is completed, the trailing edge of the document passes the document sensor 21, and when the trailing edge of the document moves to the printing position, document conveyance is stopped and the pressure plate 18
is lowered, and the microprinter 17 prints the set identification information on the original that has been read.

When printing of this identification information is completed, the conveyance roller 16 discharges the original that has been read.

Further, when reading a document image using the book scanner function, the document is placed at a predetermined position on the contact glass 1, and the pressure plate 8 presses the document from above.

When image reading is instructed in this state, the traveling body first moves the reading position of the optical system to the surface of the conveyance roller 14, and in this state, sampling of reference data for the shading correction function is performed. .

Then, the traveling body moves the reading position of the optical system to the leading edge position of the document, and moves the optical system from that position in the sub-scanning direction at a predetermined speed. Along with this, line image sensor 7
A reading operation is performed, and images of l pages of the original are read.

FIG. 3 shows an example of the microprinter 17.

The microprinter 17 has a printing window 17b corresponding to the printing width opened on the upper surface of its housing 17a, and an endless printing belt 17c having a large number of printed characters protruding from its surface directly below the printing window 17b. It is arranged.

This printing belt 17c prints at any position using a rotating mechanism (not shown)! 17b, and on its back side, hammer mechanisms (not shown) for projecting one character of the printing belt 17c from the printing window 17b are constructed for the number of printing digits. Also provided is an ink roller 17d that applies ink to the printing surface of the printing belt 17c.

Therefore, when the solenoid 31 is off,
The plunger 32a is moved in the protruding direction A by the spring 32b.
Since it is fixed at the limit position A, the shaft 28 is rotated by the link 31 in the counterclockwise direction RA in the figure, so that the 1-position regulating member 27 comes into contact with the end 18b of the pressure plate 18.

As a result, as shown in FIG. 5(a), the compression spring 26
The end 18b of the pressure plate 18, which attempts to move upward due to the biasing force F, cannot move because it is pressed by the position regulating member 27, and as a result, the opposite end 18a is separated from the printing window 17b of the microprinter 17. position.

Therefore, in this state, the original can pass through the gap between the microprinter 17 and the pressure plate 18.

On the other hand, when the solenoid 32 is turned on, the plunger 32a
is pulled in direction AB against the biasing force of spring 32b.
, the link 31 is pulled and the shaft 28 rotates in the clockwise direction RB in the figure.

As a result, the position regulating member 27 is positioned at the end 18 of the pressure plate 18
b and moves until it is stopped by the stopper 18c.

In this state, as shown in FIG. 5(b), the compression spring 2
6 acts, and the end 18a of the pressure plate 18 is inserted into the printing window 17b of the microprinter 17.

As a result, at that point, the micro printer 17 and the pressure plate 1
The microprinter 17 can print on the document located between the two.

That is, with the document stopped, the solenoid 32 is turned on to press the pressure plate 18 against the document, and the first digit of the print information to be printed at that time is output to the microprinter 17. Performs digit printing operation. Next, the data of the second digit of the printing information is output to the microprinter 17, and the microprinter 17 is caused to perform a printing operation of the second digit. By sequentially repeating this operation for all digits of the print information, the print information can be printed on the document.

FIG. 8 shows an example of processing executed when the host device H5T reads one page of a document image with the scanner SCN set to the sheet conveyance mode.

First, the scanner SCN is set to sheet conveyance mode, and the internal state of the scanner SCN is initialized.
01), outputs printed information of identification information to be added to the first document to the scanner SCN (process 102), and instructs it to start reading one page of the document (process 103).
). Here, when the 1st date and page sequence number are used as identification information, the scanner SCN is notified of the current date information and page sequence number "1".

As a result, one page of read data is input from the scanner SCN, the read data is converted into a predetermined format, necessary search information is added, and the data is stored in the optical disk device ODD (process 104). ).

When the input of one page's worth of read data is completed, it is determined whether or not the scanner SCN has notified that there is a next page (Judge 105), and the result of Judgment 105 is YES.
When this happens, the process returns to step 103 and instructs the scanner scN to start reading the next page.

Also, all documents have been read and the scanner SCN
When it is notified that there is no next page and the result of judgment 105 is NO, the reading operation is ended (process 106), a predetermined end process is executed, and the series of filing processes is ended.

FIG. 9 shows an example of processing executed by the scanner SCN when reading an image.

First, the host device is in a state of waiting for command data to be input from the IST (process 201).
, when command data is input from the host device H5T, it is determined whether the data is setting data for the sheet conveyance mode (determination 2o2).

When the result of determination 202 is NO, the process shifts to the sheet fixing mode and executes that process.

Note that the sheet fixing mode is not directly related to the present invention, so a description thereof will be omitted.

When the result of the judgment 202 is YES, the print information is initialized to the content notified from the host device H5T (203), and the process waits until a command to start reading is input from the host device H5T (NO loop of judgment 204). .

The command to start reading is input, and the result of judgment 204 is Y.
When ES is reached, the above-mentioned document image reading process is started (process 205), and until the document sensor 21 detects the trailing edge of the document, the read data input from the image reading section 54 is transferred in units of predetermined transfer data. host family M) sequentially transfer to IST (NO loop of process 206 and judgment 207)
.

When the trailing edge of the document is detected by the document sensor 21 and the result of 1 judgment 207 becomes YES, the reading process is stopped (process 208), the document conveyance is stopped, and the print information at that time is transferred to the microprocessor by the method described above. The printer 17 prints on the trailing edge of the document (process 209).

When the printing of the print information is finished, the document that has been read is ejected by the conveyance roller 16 (step 210), and the state of the document sensor 19 is checked to determine whether the next page of document remains on the document table 9 (determination step 210). 211), when the result of the judgment 211 is YES, the process 212) notifies the host device H5T that there is a next page, the process 213) that increases the number of pages of print information by one and updates the print information 213), and returns to the judgment 204. Then, it waits for a command from the host device H5T.

When the image reading operation of all originals placed on the original platen 9 has been completed, and the result of the judgment 211 is NO,
Host device 1 (process 21 to notify ST that there is no next page)
4) Finish the series of reading operations.

With the above configuration, in order for an operator to file a large number of original images, the operator places the scanned original on the original platen 9 of the scanner SCN.
For example, if you set the necessary information such as the page number of the first document to start reading in the host device H5T, and then issue a command to start reading the document, the host device H5T
After initially setting the scanner SCN to sheet transport mode, it notifies the initial value of the print information set based on information such as the page number of the first document specified by the operator, and starts the reading operation of all pages. The scanner SCN is repeatedly commanded to perform each page reading operation until the end.

As a result, the scanner SCN reads the document image in the sheet transport mode, transfers the image data obtained thereby to the host device H5T, and also reads different identification information (printed information) for each document on the image surface of the document. Print on and eject the paper.

The host device H3T attaches predetermined identification information such as search information specified by the operator to the scanner S.
The image data input from the CN is stored page by page in the optical disk device ODD.

Therefore, at the end of a series of reading operations, the image data obtained from the reading operations is stored page by page in the optical disk device ODD, and each image surface of the document that is actually read and input has identification information. is printed and ejected.

Thereby, when the reading operation is completed, the operator can collect the ejected originals to be read, thereby determining which originals have not been input for reading.

So, I collected the manuscripts that could not be read and input.

By placing the document on the document table 9 of the scanner SCN and issuing a reading command again, images of all documents to be read and input can be input.

At this time, for example, by instructing the operator to integrate the image file with the image file read and input just before, the consistency of the document images to be continuously read can be maintained.

However, the structure of the image file etc. on the host device H
It is determined based on the file system and search system realized by the ST.

By the way, in the embodiment described above, the identification information printed on the document is not input as an image, but another embodiment of the present invention in which the identification information is also input as an image will be described next.

FIG. 10 shows a scanner SC according to another embodiment of the present invention.
Part of the optical system of N is shown. In addition, in the same figure,
The same parts and corresponding parts as in FIG. 2 are given the same reference numerals.

In the figure, in this embodiment, a half mirror is used as the lR5, a second reading position is set between the microprinter 17 and the conveyance roller 16, and a light source illuminates the document at the second reading position. 60, and a mirror 61 that aligns the reflected light from the surface illuminated by the light source 60 with the optical axis from the mirror 5 to the lens 6.

The light reflected by the mirror 61 passes through the mirror 5, enters the lens 6, and forms an image on the line image sensor 7.

In this case, when the trailing edge of the document is detected by the document sensor 21 when reading the document, identification information to be added to the document is printed by the microprinter 17 in the same manner as in the embodiment described above.

Next, the light source 2 is turned off and the light source 60 is turned on. With the second reading position illuminated, the document is transported by the transport rollers 16, and the line image sensor 7 performs a reading operation accordingly.

As a result, the image of the identification information printed on one document by the microprinter 17 is read and input by the line image sensor 17, and is transferred to the host device H5T as subsequent image data of the same document.

As a result, the identification information added to the document is also stored in the optical disk device ODD as image data of the document.

Therefore, when searching for an image file at a later date, the operator can confirm identification information such as the reading date of the document, which is helpful in searching for information.

Note that the identification information to be added to the manuscript is not limited to that in the above-described embodiment, and other information may be added.

[Effects of the Invention] As explained above, according to the present invention, since unique identification information is printed on each original that has been read, it is possible to reliably identify originals that have not been read, and It is possible to prevent image reading omissions. Furthermore, since the printed identification information is also read and inputted, an advantage is obtained in that the identification information can be referred to at a later date to perform information retrieval work.
