Description

The present invention relates to a card recording device that records by printing or the like on a card.

In recent years, the population carrying My Number cards and residence cards has been increasing, but with such ID cards for identity verification, when information about the card holder (hereinafter referred to as the user) such as the address changes, the card It is a rule to write and record the changes on the back side of.

The most orthodox method is to record the changes by handwriting by the staff of local governments, government offices, public institutions, etc. However, due to concerns about mistakes and the narrow description area, recently, instead of handwriting, Patent Document 1 etc. It is common to use a card printer such as the above, and the card can be inserted into a card printer installed at a government office or the like, and the changed contents can be printed on the card by the printing unit in the card printer.

Japanese Unexamined Patent Publication No. 2010-262420

In order for the card printer to print the changed contents correctly, it is necessary that the cards are inserted into the card printer in the correct arrangement according to the configuration of the printing unit or the like and transported to the printing unit.

For example, if the user inserts the card into the card printer with the wrong side facing up, or inserts the card into the card printer in the wrong direction, the card printer may not print correctly, and the card printer may not print properly. It is necessary to detect the correctness of the orientation and take appropriate processing.

In such correct / incorrect detection, usually, feature points are extracted from the captured image of the card, and the front and back sides and orientation of the card are determined using the feature points. However, if the design of the card is changed, it may not be possible to extract the feature points from the image well, and there has been a demand for a method that can more preferably detect the correctness of the front and back and the orientation of the card.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a card recording device or the like that can suitably detect the correctness of the front and back sides and orientation of a card.

The present invention for solving the above-mentioned problems is a card recording device that records on a card in which a predetermined character is formed in a predetermined area, and when recording on the card, the front and back sides of the card The card recording device is characterized in that it performs OCR processing on an image obtained by capturing the card to determine whether or not the predetermined character exists in the predetermined area in order to detect the correctness of the orientation.

In the present invention, the correctness of the front and back sides and the orientation of the card is detected by using the reading result of a predetermined predetermined character existing in a predetermined area of the card instead of the feature point of the image as in the conventional case. For example, it is assumed that the front and back sides and orientation of the card are correct when a predetermined character is read, and at least one of the front and back sides and orientation of the card is incorrect when the predetermined character cannot be read. In this way, by using the character reading result, it is possible to accurately detect the correctness of the front and back and the orientation of the card, and it is possible to detect even if the character font is changed. In addition, predetermined characters predetermined on the card are often necessary as information on the card, and are rarely changed as in the design.

The predetermined character is a plurality of characters, and whether or not the predetermined character exists in the predetermined area by comparing a score indicating the number of characters correctly read from the image among the predetermined characters with a threshold value. It is desirable to determine whether or not. Further, it is desirable that the predetermined characters are formed in a plurality of the predetermined areas.
By using the above score for the determination, it is possible to suitably detect the correctness of the front and back and the orientation of the card even in a case where some characters cannot be read due to dirt or the like. Further, the stability of the detection process can be improved by assuming that the predetermined characters used for correct / incorrect detection are formed in a plurality of regions.

The predetermined character is, for example, a character of a pre-printed portion of the card.
The predetermined characters are typically characters of the pre-printed part such as "update history" indicating the entry field of the change contents and "remarks" indicating the entry field of the remarks, and are used as card information. It is necessary and rarely changed like the design.

It is desirable that the card recording device further performs OCR processing on the image obtained by rotating the image by 180 ° to further determine whether or not the predetermined character exists in the predetermined region. Further, the card recording device has a camera that performs the shooting from a predetermined position, shoots the card with the front and back reversed by the camera, acquires an image, performs OCR processing on the image, and performs the predetermined shooting. It is also desirable to further determine whether or not the character is present in the predetermined area.
This makes it possible to identify the correctness of the front and back and the orientation of the card in more detail.

In the card recording device, the predetermined characters are displayed on any of an image of the card taken by the camera, an image of the card with the front and back reversed taken by the camera, and an image of each image rotated by 180 °. If it is determined that the card does not exist in the predetermined area, it is also desirable to eject the card without recording on the card.
In the present invention, when it is determined that a predetermined character does not exist in a predetermined area for any of the above images, the card is ejected by notifying the user of the fact as a reading failure without recording on the card. be able to.

The card recording device records, for example, by printing on the card. It is desirable that the card recording device corrects the orientation of the characters to be printed according to the correctness of the orientation of the card and prints on the card.
The card recording device records by printing on a card like the above-mentioned card printer, and corrects the orientation of the card by correcting the orientation of the characters to be printed according to the correctness of the orientation of the card. Printing can be performed correctly without any problems.

The card is, for example, an ID card, and the predetermined character is formed on the back surface of the card.
The surface of the ID card is often complicated in design, such as a hologram for preventing counterfeiting, which may make it difficult to detect the correctness of the front and back of the card. On the other hand, the design of the back surface of the ID card is less complicated by holograms and the like, and the detection process can be performed more accurately by using the reading result of the characters on the back surface.

Of these, the issue number of the card 3, the user's name, the face image, etc. are on-demand information that differs depending on the individual card 3, the character parts other than the face image are subjected to the molten thermal transfer method, and the face image is obtained by the sublimation thermal transfer method. It is formed by printing on a card substrate.

On the other hand, the issue number of the card 3 and the characters of "number" and "name" indicating the entry field of the user's name are commonly used in each card 3. These characters are predetermined on the card 3, and are formed in advance in a predetermined area on the card substrate by a printing method such as an offset printing method or a letterpress printing method before printing the on-demand information, and a pre-printed portion. Is called. The structure of the on-demand information and pre-printed part differs depending on the type of card 3 such as residence card, My Number card, special permanent resident card, and driver's license.

FIG. 4B schematically shows an example of the back surface of the card 3. The back side of the card 3 is a writable writing surface, and is provided with an update history entry field and a remarks entry field. The characters 31 of "update history" and the characters 31 of "remarks" indicating each entry field are the above-mentioned pre-printed parts, and these predetermined characters 31 are formed in a predetermined area.

The change of the user information is, for example, a change of the user's address, and the card printer 1 prints and records the change contents in the update history entry field on the back surface of the card 3.

Here, as shown in FIG. 1, the camera 12 and the printing unit 13 of the card printer 1 are installed at predetermined positions above the transport path a, and the changed contents of the user information are printed on the back surface of the card 3 as described above. To do. Therefore, the card 3 needs to be inserted through the insertion slot 16 with the back side shown in FIG. 4B facing up, and transported to the printing unit 13 in the housing 15.

Further, in the present embodiment, the correct orientation of the card 3 at this time is the orientation shown in FIG. 4B. For example, the card 3 is inserted into the insertion slot 16 in the orientation rotated by 180 ° on a flat surface, and the inside of the housing 15 is inserted. If it is conveyed to the printing unit 13 as it is, the changed contents cannot be printed at the correct position on the back surface of the card 3.

Therefore, in the present embodiment, the correctness of the front and back and the orientation of the card 3 inserted into the card printer 1 is detected by the following processing. By performing appropriate processing according to the detection result, the changed contents of the user information can be correctly printed and recorded in the update history entry field on the back surface of the card 3.

(3. Processing performed by the card printer 1)
FIG. 5 is a flowchart showing a process performed by the card printer 1 when recording the changed contents of the user information, and each step of FIG. 5 is executed by the control device 11 of the card printer 1 controlling each part of the card printer 1. To do.

When the card 3 is inserted into the housing 15 from the insertion slot 16, the card printer 1 conveys the card 3 to the position of the camera 12, takes a picture of the card 3 from above by the camera 12, and acquires the image (the card printer 1). S1). FIG. 6 shows an image 100 when the card 3 is correctly inserted, and the back surface of the card 3 arranged in the correct orientation is photographed.

Then, the card printer 1 determines whether or not a predetermined character exists in a predetermined area of the image 100 (S2).

In the present embodiment, the image 100 is converted to grayscale, a plurality of regions A and B shown in FIG. 6 are cut out from the image 100 as the predetermined regions, and OCR (optical) known for the images of these regions A and B is obtained. Character recognition) processing is performed. If the card 3 is inserted correctly, the area A has the characters 31 of "change", "new", "wear", and "history", and the area B has the characters 31 of "bi" and "remark". In the present embodiment, OCR processing is performed to determine whether or not these predetermined characters 31 can be read from the areas A and B.

The criterion for S2 is not particularly limited, but it is possible that, for example, the card 3 is dirty and some characters cannot be read normally even if the card 3 is inserted correctly. Therefore, in the present embodiment, how many characters out of the plurality of characters 31 existing in the areas A and B are correctly read is calculated as a score, and the score is compared with the threshold value for determination. For example, the character 31 of "new" in the area A cannot be read due to the dirt on the card 3, and the other characters 31 of "change", "wear", and "history" can be read. If the character 31 of "Consideration" can be read, the score is set to 5 which is the number of correctly read characters or 5/6 which is the ratio of the number of characters to the total number of characters, and this is compared with the threshold value.

When the above score is equal to or higher than the threshold value, the card printer 1 determines that the predetermined character 31 exists in the predetermined areas A and B (S2; YES), and the card printer 1 has the card printer 1 as shown in [Case a] of FIG. Assuming that the back side of the inserted card 3 is correctly facing up and the orientation of the card 3 is also correct, the process proceeds to print the changed contents of the user information.

Here, the card printer 1 transmits the image 100 captured earlier to the computer 2, the computer 2 displays the image 100 as an editing screen on the display unit 23, and accepts the input of the changed content of the user information.

FIG. 8A is an example of this editing screen, and the image 100 acquired by the camera 12 is displayed in the display area 231. On the edit screen, an input area 232 is provided above the display area 231, and the user inputs changes to the input area 232. By performing image analysis of the image 100, the computer 2 determines the area where the changed contents can be printed so as to avoid the area where the changed contents have already been recorded, and the input changed contents are shown in FIG. 8 (b). It is displayed in the determined area C as described above.

Reference numeral 233 in FIG. 8 is a print button, and the user confirms that the changes displayed in the area C are correct and selects the print button 233. As a result, the printing of the changed contents is instructed, and the computer 2 transmits the changed contents and the information of the area C for printing the changed contents (sometimes referred to as the changed contents) to the card printer 1.

When the card printer 1 receives the above-mentioned changed contents (S3), the card printer 1 conveys the card 3 to the printing unit 13 and prints the changed contents in the above-mentioned area C on the back surface of the card 3 (S4), and the printed card 3 Is discharged to the insertion port 16.

On the other hand, as shown in [Case b] of FIG. 7, the orientation of the card 3 inserted in the card printer 1 is incorrect, or as shown in [Case c], the front and back of the inserted card 3 are incorrect, or [ If both the front and back sides and the orientation of the inserted card 3 are incorrect as shown in [Case d], it is determined that the predetermined characters 31 described above do not exist in the predetermined areas A and B of the image 100 of the card 3 (S2). ; NO).

In this case, the card printer 1 assumes that at least one of the front and back sides and the orientation of the inserted card 3 is incorrect, and proceeds to the following processing.

That is, the card printer 1 first rotates the image 100 by 180 ° (S5), and whether or not the predetermined character 31 exists in the predetermined areas A and B of the rotated image 100'(see FIG. 7). Is further determined (S6).

The determination method is the same as in S2 described above, and when the card printer 1 determines that there are predetermined characters in the predetermined areas A and B of the image 100'(S6; YES), in [Case b] of FIG. As shown, the back side of the card 3 inserted in the card printer 1 is correctly facing up, but the orientation is not correct.

In this case, the card printer 1 transmits the image 100'to the computer 2 to display the image 100' in the display area 231 (see FIG. 8) of the editing screen, and the changed contents input to the computer 2 in the same manner as described above. Etc. are received from the computer 2 (S7).

After that, the card printer 1 conveys the card 3 to the printing unit 13 and rotates the changes received in S7 by 180 ° about the position corresponding to the center of the card 3 as shown by the arrow in FIG. 9 (a). S8), align with the orientation of the card 3 inserted in the card printer 1.

Then, as shown in FIG. 9B, the characters of the changed content after the rotation are printed in the area C after the rotation on the back surface of the card 3 (S9), and the printed card 3 is ejected to the insertion slot 16. To do. By correcting the orientation of the characters and the position of the area C of the changed contents in this way and printing, if the card 3 is inserted into the card printer 1 by mistake in the orientation, the orientation of the card 3 is not corrected. Correct printing is possible.

On the other hand, when it is determined in S6 that the predetermined characters 31 do not exist in the predetermined areas A and B of the image 100'(S6; NO), the card printer 1 has the front and back sides of the card 3 incorrect and the front side faces upward. Then, the card 3 is conveyed to the position of the reversing mechanism 143 and the front and back sides are reversed (S10).

Then, the card printer 1 conveys the card 3 to the position of the camera 12 again, takes a picture of the card 3, and acquires the image 100 again (S11). After that, the card printer 1 determines whether or not the predetermined character 31 exists in the predetermined areas A and B of the image 100 in the same manner as described above (S12).

When it is determined that the predetermined characters 31 exist in the predetermined areas A and B of the image 100 (S12; YES), the card printer 1 is a card inserted into the card printer 1 as shown in [Case c] of FIG. Assuming that only the front and back sides of 3 are incorrect and the orientation of the card 3 is correct, the image 100 is transmitted to the computer 2 to be displayed in the display area 231 (see FIG. 8) of the editing screen, and the computer 2 is the same as the above S3. The change contents and the like input to are received from the computer 2 (S13). Then, the card 3 whose front and back sides are turned upside down in S10 is conveyed to the printing unit 13 as it is, and the changed contents are printed on the back side of the card 3 as in S4. (S14), the printed card 3 is ejected to the insertion slot 16.

On the other hand, when it is determined that the predetermined character 31 does not exist in the predetermined areas A and B of the image 100 (S12; NO), the card printer 1 rotates the image 100 by 180 ° (S15) as in the above S5. Whether or not the predetermined character 31 exists in the predetermined areas A and B of the rotated image 100'is determined in the same manner as described above (S16).

When it is determined that the predetermined characters 31 exist in the predetermined areas A and B of the image 100'(S16; YES), the card printer 1 is inserted into the card printer 1 as shown in [Case d] of FIG. Assuming that both the front and back sides and the orientation of the card 3 are incorrect, the image 100'is sent to the computer 2 to be displayed in the display area 231 (see FIG. 8) of the editing screen, and is displayed on the computer 2 in the same manner as in S7. The input changes and the like are received from the computer 2 (S17).

Then, the card 3 with the back surface facing upward is conveyed to the printing unit 13, and the changes and the like are rotated by 180 ° about the position corresponding to the center of the card 3 as in S8 above (S18). ), The changed contents after rotation are printed on the back surface of the card 3 (S19), and the printed card 3 is ejected to the insertion slot 16.

On the other hand, when it is determined in S16 that the predetermined characters 31 do not exist in the predetermined areas A and B of the image 100'(S16; NO), the computer 2 fails to read the card 3 (S20), and the printing unit 13 determines. Without printing, the image is discharged from the insertion slot 16 as it is, and the process is completed. At this time, it is also possible to output a message such as "Please insert the card correctly" on the monitor or speaker (not shown) of the card printer 1.

As described above, in the present embodiment, the front and back sides of the card 3 are used not as the feature points of the image as in the conventional case, but as the reading result of the predetermined predetermined characters 31 existing in the predetermined areas A and B of the card 3. Detects the correctness of the direction. For example, it is assumed that the front and back sides and orientation of the card 3 are correct when the predetermined character 31 is read, and at least one of the front and back sides and orientation of the card 3 is incorrect when the predetermined character 31 cannot be read. In this way, by using the reading result of the character 31, it is possible to accurately detect the correctness of the front and back sides and the orientation of the card 3, and it is possible to detect the correctness even if the character font is changed. Further, the predetermined character 31 predetermined in the card 3 is often necessary as the information of the card 3, and is rarely changed as in the design.

Further, by setting a plurality of characters 31 to be read and calculating a score indicating the number of correctly read characters 31 among them and using it for judgment, even in a case where some characters 31 cannot be read due to dirt or the like, the card 3 It is possible to suitably detect the correctness of the front and back and the direction of the above. Further, by forming the predetermined characters 31 used for correct / incorrect detection in the plurality of areas A and B, the stability of the detection process can be improved.

Further, in the present embodiment, OCR processing is performed on the image 100'in which the image 100 of the card 3 is rotated by 180 °, or OCR processing is performed on the image 100 of the card 3 whose front and back sides are inverted by the camera 12. By doing so, as described above, the correctness of the front and back and the orientation of the card 3 can be specified in more detail.

Further, in the present embodiment, any of the image 100 in which the card 3 is photographed by the camera 12, the image 100 in which the card 3 is inverted and the card 3 is photographed by the camera 12, and the image 100'in which each image 100 is inverted by 180 ° When it is determined that the predetermined character 31 does not exist in the predetermined areas A and B, the card 3 can be ejected by notifying the user of the fact without printing on the card 3 as a reading failure. If NO is determined in S2 (see FIG. 5), the card 3 may not be printed, and the user may be alerted and the card 3 may be ejected in the same manner as described above.

Further, the card printer 1 of the present embodiment records by printing on the card 3, and prints according to the correctness of the orientation of the card 3. The characters or the like of the changed contents are rotated by 180 ° to determine the orientation of the characters or the like. By making corrections, printing can be performed correctly without correcting the orientation of the card 3.

Further, in the present embodiment, it is assumed that the predetermined character 31 is formed on the back surface of the ID card. Although it is possible to use the predetermined character 31 as the character of the pre-printed portion on the surface of the ID card, the design is often complicated on the surface of the ID card, such as a hologram for preventing counterfeiting. Therefore, the correctness detection of the front and back sides and the orientation of the card 3 may not be successful. On the other hand, the design of the back surface of the ID card is less complicated by holograms and the like, and the detection process can be performed more accurately by using the reading result of the characters on the back surface.

However, the present invention is not limited to the above embodiments. For example, the card printer 1 of the present embodiment prints and records the changed contents of the user information on the back surface of the card 3, but the contents to be recorded and the surface for recording the contents are not limited to the above, and the recording method is also used. It is not limited to printing. For example, when recording is performed on the contact type IC chip of the card 3, the correctness of the front and back and the orientation of the card 3 can be detected by the same procedure as described above, and the detection result can be used for correct recording. Further, the card 3 is not limited to the ID card described above.

Further, the card printer 1 of the present embodiment is a small one installed in a government office or the like and records the changed contents of the user information of the ID card. However, the configuration of the card printer 1 of the present embodiment is the card 3. It can also be applied to large card printers used in factories when issuing new products.

Further, in the present embodiment, the characters 31 of the pre-printed portion such as "update history" indicating the entry field of the update history and "remarks" indicating the entry field of the remarks are used as the predetermined characters 31 to be read. These characters 31 are necessary as information on the card 3 and have the advantage that they are rarely changed as in the design. However, even if the characters 31 are predetermined, that is, the characters have the correct answer of the reading result. It can be used for judgment.

Further, the correctness of the front and back and the orientation of the card 3 differs depending on the arrangement of the camera 12 for taking a picture, the printing unit 13 for printing, and the like. For example, when the printing unit 13 is below the transport path a of the card 3, the front and back sides of the card 3 are correct when the card 3 is inserted into the card printer 1 with the front side facing up.

Further, in the present embodiment, the camera 12 is provided only above the transport path a, but it is also possible to provide the camera 12 above and below the transport path a. In this case, the front and back sides of the card 3 are set in S10 to S11. Instead of flipping and shooting the card 3, the camera 12 that shoots may be changed. Similarly, the printing unit 13 can also be provided above and below the transport path a. In this case, the printing unit 13 for printing may be changed according to the correctness of the front and back of the card 3.

Although preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to such examples. It is clear that a person skilled in the art can come up with various modifications or modifications within the scope of the technical idea disclosed in the present application, and these also naturally belong to the technical scope of the present invention.
