Description

This invention relates to a technique for reading and processing information indicated by the information code information code such as a two-dimensional code is formed on the information medium body formed.

Conventionally, as one of the information symbols, there is a two-dimensional code such as a QR code (registered trademark). In addition, the use of two-dimensional codes is being studied in various systems. For example, there is a ticket gate system in which a ticket (ticket, etc.) forming a two-dimensional code indicating ticket information is issued, and the ticket information indicated by the two-dimensional code is read by an automatic ticket gate to perform ticket gate processing. In a ticket gate system that uses a ticket (a ticket in which the two-dimensional code is not formed on the back side) in which the two-dimensional code is formed only on one side (hereinafter referred to as the front side), the automatic ticket gate uses the ticket gate passage. Even if a passing user holds the back side of the ticket over the reading area of the two-dimensional code, it cannot be detected that the back side of the ticket is held. Therefore, the automatic ticket gate determines that the user holding the back of the ticket is a non-ticket person who does not have the ticket, and does not allow the passage through the ticket gate. That is, it is not possible to guide the user who holds the back surface of the ticket in the reading area of the two-dimensional code to hold the opposite side in the reading area of the two-dimensional code.

It has been proposed that a ticket vending machine or the like issues a ticket using a roll paper having a two-dimensional code formed on the back surface at appropriate intervals (see Patent Document 1). Ticket vending machines, etc. print a two-dimensional code indicating ticket information on the surface of roll paper to issue a ticket. As a result, the issued ticket has a two-dimensional code indicating the ticket information formed on the front surface and a two-dimensional code indicating the back surface formed on the back surface. Therefore, when a user passing through the ticket gate passes the back side of the ticket over the reading area of the two-dimensional code, the automatic ticket gate reads the two-dimensional code indicating that the back side of the ticket is the back side. It is possible to detect that it has been done. Therefore, it is possible to guide the user who holds the back surface of the ticket in the reading area of the two-dimensional code to hold the opposite side in the reading area of the two-dimensional code.

Japanese Unexamined Patent Publication No. 2014-182432

However, in the configuration described in Patent Document 1, since the two-dimensional code is formed on both the front surface and the back surface of the ticket, the number of users who misidentify the two-dimensional code held in the reading area is increased (reading). The number of users who mistakenly recognize the two-dimensional code held in the area as the two-dimensional code formed on the back surface is increased). As a result, the number of users who hold the back side of the ticket in the reading area of the two-dimensional code increases, and the processing efficiency of the ticket gate processing is lowered.

An object of the present invention is to provide a technique capable of suppressing an increase in the number of users who misidentify an information code to be held in the reading area of an information code and providing guidance to a user who does not properly hold the information code in the reading area. It is in.

The information medium processing apparatus of the present invention is configured as follows in order to achieve the above object.

The information medium processing apparatus processes an information medium in which a first information code indicating the first information and a second information code indicating the second information are formed .

The first information code reflects the irradiated light of the first wavelength when the light of the first wavelength is irradiated, and the second information code is irradiated when the light of the second wavelength is irradiated. It has the optical property of reflecting light of the wavelength of. The second information code prevents the reflection of the irradiated light of the first wavelength when the light of the first wavelength is irradiated, and is irradiated when the light of the second wavelength is irradiated. It has optical characteristics that reflect light of two wavelengths. The first wavelength and the second wavelength are different wavelengths. Further, a part of the first information code is covered with a first covering portion having optical characteristics that allow light of the second wavelength to be transmitted and hinder the transmission of light of the first wavelength.

Therefore, this information medium cannot read the first information indicated by the first information code and the second information indicated by the second information code when irradiated with light of the first wavelength. Further, when the information medium is irradiated with light having a second wavelength , the first information indicated by the first information code and the second information indicated by the second information code can be read.

In particular, the light having the first wavelength should be visible light, and the light having the second wavelength should be light that is not visible light (infrared light or ultraviolet light). In this way, the first information code is easy to see, but the second information code is hard to see. Therefore, it is possible to suppress an increase in the number of users who mistakenly recognize that the information code to be held in the reading area is the second information code. In addition, it is possible to reliably guide the user who holds the second information code in the reading area.

If the information medium is a sheet-shaped medium or a card-shaped medium (a medium having a thickness of several tens of μm to several mm), a first information code is formed on one of the front surface and the back surface. It is preferable to form a second information code on the other surface. If the information medium has a three-dimensional shape (for example, a hexahedron or an octahedron), the first information code is formed on one or more faces, and the second information code is formed on one or more faces. Is preferable. However, the first information code and the second information code should not be formed on the same surface.

Further, the first information may be information indicating the attributes of the medium, and the second information may be information indicating that the information code should not be held in the reading area. In this way, the second information can have the same information code between the information media.

Information medium processing apparatus includes a second illumination section for illuminating a first illumination unit which irradiates light of a first wavelength to the reading area of the information medium, the light of the second wavelength to the reading area of the information medium It is provided with an imaging unit that captures an image of a reading region and a determination unit. The determination unit is a first captured image in which the reading region is imaged by the imaging unit in a state where the first illumination unit turns off the light of the first wavelength and the second illumination unit turns on the light of the second wavelength. After the first captured image is captured, the reading region is imaged by the imaging unit with the first illumination unit turning on the light of the first wavelength and the second illumination unit turning off the light of the second wavelength. After capturing the second captured image and the second captured image in the read region, the first illumination unit turned off the light of the first wavelength again, and the second illumination unit turned on the light of the second wavelength. In this state, the third image captured in which the reading area is captured by the imaging unit is processed, and it is determined whether the information code held in the reading area is the first information code or the second information code. This determination unit cannot read the information indicated by the information code captured for at least one of the first captured image and the third captured image, or the information code captured in the second captured image. When the information indicated by is read, it is not determined that the information code held in the reading area is the first information code.

According to this configuration, it is possible to suppress an increase in the number of users who misidentify the information code to be held in the reading area of the information code, and to guide users who do not properly hold the information code in the reading area.

Further, when the determination unit determines that the information code held in the reading area is the first information code, the information medium processing device uses the first information indicated by the first information code to provide information. When the media processing unit that processes the medium and the determination unit determine that the information code held in the reading area is the second information code, the first information code is placed in the reading area. It may be configured to include a guide unit for guiding.

According to the present invention, it is possible to suppress an increase in the number of users who misidentify the information code to be held in the reading area of the information code. In addition, it is possible to provide guidance to users who do not properly hold the information code in the reading area.

The communication unit 108 communicates with other station affairs equipment such as an automatic ticket gate 5 and a station server (not shown) via a network.

Here, the ticketing of the ticket 1 in the ticketing unit 104 will be described. FIG. 3A is a diagram for explaining the ticketing unit, and FIG. 3B is a diagram showing the back surface of Mr. Roll. FIG. 4 (A) is a diagram showing the front surface and the back surface of the ticket issued by the ticket issuing unit, and FIG. 4 (B) is a diagram showing the front surface and the back surface of the one-day ticket issued by the ticket issuing unit. Is. A roll paper 110 is set in the ticketing unit 104. The ticketing unit 104 forms a two-dimensional code 2 indicating ticket information, characters, and the like on one surface (hereinafter, referred to as the front surface) of the roll paper 110 by the print head 111. The two-dimensional code 2 is, for example, a QR code (registered trademark). Further, the ticketing unit 104 cuts the portion on which the two-dimensional code 2 is printed with the cutter 112 and discharges it as a ticket 1 to the ticketing slot. The two-dimensional code 2 corresponds to the first information code referred to in the present invention. The ticket information indicated by the two-dimensional code 2 is an attribute of the ticket 1. The attributes of the ticket 1 are identification information for identifying the ticket 1, type information indicating the type of the ticket (ticket, one-day ticket, etc.), validity period information indicating the validity period of the ticket, and valid section of the ticket. This is valid section information indicating. The ticket information is information unique to the issued ticket 1.

Further, as shown in FIG. 3B, the two-dimensional code 3 is pre-printed on the back surface of the roll paper 110 at substantially regular intervals. This two-dimensional code 3 is information indicating that it is the back surface of the ticket 1. The two-dimensional code 3 corresponds to the second information code referred to in the present invention. The two-dimensional code 3 may be any information as long as it is information indicating that it is not the ticket information indicated by the two-dimensional code 2 (here, it is referred to as information indicating the back surface). Further, the information indicated by each two-dimensional code 3 may be the same or different. As will be described later, this two-dimensional code is formed of ink that is difficult for the user to see. L1 shown in FIG. 3 (B) indicates the size of the minimum size ticket 1 (in this example, ticket 1a) to be issued, and L2 shown in FIG. 3 (B) is the maximum size ticket 1 to be issued. (In this example, the size of the one-day ticket 1b) is shown. The interval of the two-dimensional codes 3 in the winding direction of the roll paper 110 is (L1 / 2) or less. Further, as shown in FIG. 3B, in this example, three two-dimensional codes 3 are printed side by side in a direction orthogonal to the winding direction of the roll paper 110. Therefore, at least three or more two-dimensional codes 3 are printed on the back surface of the ticket 1 issued by the ticket vending machine 10 without being affected by the cutting position in the winding direction of the roll paper 110.

It is sufficient that one or more two-dimensional codes 3 are printed in the direction orthogonal to the winding direction of the roll paper 110.

Here, the two-dimensional code 2 and the two-dimensional code 3 will be described.

As is known, the two-dimensional codes 2 and 3 are two modules having different light reflection characteristics arranged in a code region. The code area is approximately square. The two-dimensional codes 2 and 3 form symbols at the three corners of the code area for detecting the direction of the code area (directions of the two-dimensional codes 2 and 3). In the code area, two modules having different light reflection characteristics are arranged according to the information of the two-dimensional codes 2 and 3. A module is the smallest unit cell constituting the two-dimensional codes 2 and 3, and one module corresponds to 1-bit data. The information of the two-dimensional codes 2 and 3 can be read by reading the array of modules in the code area. Specifically, the information indicated by the two-dimensional codes 2 and 3 can be read by processing the captured image obtained by capturing the two-dimensional codes 2 and 3 and reading the arrangement of the modules in the code region.

The symbol is also composed of a plurality of modules.

Further, the two-dimensional code 2 is formed by an ink that reflects the irradiated visible light when it is irradiated with visible light (light of the first wavelength referred to in the present invention). Therefore, the user can visually recognize the two-dimensional code 2 printed (formed) on the surface of the ticket 1. Further, the two-dimensional code 2 reflects the irradiated infrared light even when it is irradiated with infrared light other than visible light (light having a second wavelength referred to in the present invention). Therefore, the two-dimensional code 2 can image the two-dimensional code 2 regardless of whether it is irradiated with visible light or infrared light. That is, the two-dimensional code 2 can read information by processing the captured image regardless of whether the captured image is irradiated with either visible light or infrared light.

On the other hand, the two-dimensional code 3 is formed of an ink that prevents reflection of the irradiated visible light when it is irradiated with visible light. Therefore, the two-dimensional code 3 formed on the back surface of the ticket 1 is difficult for the user to see (FIGS. 3 and 4 show the two-dimensional code 3 so that the two-dimensional code 3 can be visually recognized for convenience of explanation. Only.). Further, the two-dimensional code 3 reflects the irradiated infrared light when the infrared light is irradiated. Therefore, the two-dimensional code 3 cannot image the two-dimensional code 3 even if it is irradiated with visible light, but can image the two-dimensional code 3 by irradiating it with infrared light. That is, the two-dimensional code 3 cannot read the information even if the captured image when irradiated with visible light is processed, but the information can be read by processing the captured image when irradiated with infrared light. it can.

Further, in order to prevent the two-dimensional code 2 printed on the ticket 1 from being illegally duplicated by copying or the like, the covering portion 11 shown in FIG. 5 may be formed. The two-dimensional code 2 shown in FIGS. 5 (A) and 5 (B) is irradiated with either visible light or infrared light, similarly to the two-dimensional code 2 shown in FIGS. 4 (A) and 4 (B). However, it reflects the irradiated light.

When the covering portion 11 is irradiated with visible light, the covering portion 11 prevents the transmission of the reflected light from the module located in the region where the covering portion 11 is provided. Further, when the covering portion 11 is irradiated with infrared light, the covering portion 11 transmits the reflected light from the module located in the region where the covering portion 11 is provided. For example, the covering portion 11 is a region formed by the ticketing portion 104 by applying an ink having such characteristics (for example, an infrared transmissive ink). The covering portion 11 corresponds to the first covering portion referred to in the present invention. The covering portion 11 is formed so as not to overlap the symbols formed at the three corners of the cord region.

Therefore, when the two-dimensional code 2 forming the covering portion 11 is irradiated with visible light and imaged, the module of the portion overlapping the covering portion 11 is not imaged (the module of the portion not overlapping the covering portion 11 is imaged). ). On the other hand, when the two-dimensional code 2 forming the covering portion 11 is irradiated with infrared light and imaged, the module of the portion overlapping the covering portion 11 is imaged (the module of the portion not overlapping the covering portion 11 is also imaged). It will be imaged.)

The size of the covering portion 11 in the code region may be a size that fails to read the information of the two-dimensional code 2 captured by irradiating visible light. The covering portion 11 in the code area has a size that cannot be restored by the restoration ability of the error correction level of the two-dimensional code 2, for example, a size of 30% or more of the code area.

The two-dimensional code 2 forming the covering portion 11 cannot read information even if the captured image captured by irradiating visible light is processed, but processes the captured image captured by irradiating infrared light. Information can be read by.

Therefore, the two-dimensional code 2 forming the covering portion 11 can be prevented from being illegally duplicated by copying or the like.

Further, the two-dimensional code 3 formed on the back surface of the roll paper 110 may also have a covering portion 12 having the same optical characteristics as the covering portion 11 described above. FIG. 6A is an example in which the covering portion 12 is formed so as not to overlap the symbols formed at the three corners of the code region of the two-dimensional code 3 formed on the back surface. FIG. 6B is an example in which the covering portion 12 is formed on the entire back surface. FIG. 6C is an example in which the covering portion 12 is formed on substantially the entire back surface so that the character string related to the guidance message "Please hold the two-dimensional code on the opposite surface" is a blank character. 6 (B) and 6 (C) cover the two-dimensional code 3 with the covering portion 12 (the two-dimensional code 3 is formed as shown in FIG. 4 (B)).

Therefore, even when the covering portion 12 shown in FIGS. 6A, 6B, and 6C is provided, the two-dimensional code 3 can read the information even if the captured image when irradiated with visible light is processed. However, the information can be read by processing the captured image when irradiated with infrared light.

As described above, since it is difficult for the user to visually recognize the two-dimensional code 2 formed on the front surface and the two-dimensional code 3 formed on the back surface of the ticket 1, the boarding should be held in the reading area. It is possible to suppress the increase in the number of users who misidentify the surface of ticket 1. In addition, it is possible to provide guidance to the user who holds the back surface of the ticket 1 in the reading area.

Next, the automatic ticket gate 5 will be described. The automatic ticket gate 5 according to this example is installed at the ticket gate of a station. Here, an entrance unit that performs ticket gate processing for users entering the station yard and an entry unit that performs ticket gate processing for users entering the station yard are arranged facing each other for entrance. The automatic ticket gate 5 in which the user's passage direction in the ticket gate passage formed between the unit and the entry unit is bidirectional (the direction of entering the station yard and the direction of exiting from the station yard) will be described as an example. ..

The reading unit 51a is attached to the entry unit. Further, the reading unit 51b is attached to an entrance unit (not shown). The details of the reading unit 51 will be described later, but the reading unit 51 corresponds to the information medium processing device referred to in the present invention.

The IC ticket information reading unit 52 (52a, 52b) can read the ticket information for the non-contact IC ticket by wireless communication with the non-contact IC ticket held in the wireless communication area by the user passing through the ticket gate. , Write the ticket information.

Further, the imaging area of the reading unit 51b and the wireless communication area of the IC ticket information reading unit 52b are provided near the entrance of the ticket gate passage for the user who enters the station yard.

The collection unit 53 collects the used ticket 1 in this use. The collection unit 53 is provided in the entry unit, not in the entry unit. The collection unit 53 opens and closes the shutter provided in the ticket collection port 53a. The ticket collection port 53a is provided near the imaging region of the reading unit 51a.

The user detection unit 54 detects the position of the user located in the ticket gate passage by a plurality of sensors arranged along the ticket gate passage. The user detection unit 54 is attached to a plurality of light emitting elements attached along the ticket gate passage to one unit arranged so as to face each other across the ticket gate passage, and to a position where each light emitting element faces the other unit. It has a plurality of light receiving elements. If there is a light receiving element that does not receive the light emitted from the light emitting element, the user detection unit 54 determines that the user is at a position corresponding to the light receiving element.

The display unit 55 includes two indicators for displaying a message to a user passing through the ticket gate passage. One of the indicators is attached to the entry unit and displays a message to the users who enter from the station yard. The other display is attached to the entrance unit and displays a message to users entering the station yard. The display unit 55 corresponds to the guide unit referred to in the present invention.

The door opening / closing unit 56 opens the door provided on the exit side of the user when allowing the user to pass through the ticket gate passage. Further, the door opening / closing unit 56 closes the door provided on the exit side of the user when the user is not allowed to pass through the ticket gate passage. The door 56a shown in FIG. 8 is a door that opens and closes for a user entering the station yard.

The communication unit 57 controls data communication with a station server or the like (not shown).

Here, the reading unit 51 (51a, 51b) will be described. The reading units 51a and 51b have the same configuration. FIG. 9 is a block diagram showing a configuration of a main part of the reading unit. The reading unit 51 includes a control unit 60, a first irradiation unit 61, a second irradiation unit 62, an imaging unit 63, a reading unit 64, and an output unit 65.

The control unit 60 controls the operation of each unit of the reading unit 51 main body. The control unit 60 has a computer (processor) that controls the operation of the main body of the reading unit 51, and this computer executes the information medium processing method according to the present invention. The information medium processing program according to the present invention is a program installed in a computer included in the control unit 60. The control unit 60 has a configuration corresponding to the determination unit referred to in the present invention.

The first irradiation unit 61 irradiates the reading region with visible light. The second irradiation unit 62 irradiates the reading region with infrared light. The imaging unit 63 images the reading region.

The reading unit 64 processes the image of the reading area captured by the imaging unit 63, and reads the array of modules in the code areas of the two-dimensional codes 2 and 3 captured in this image, so that the two-dimensional image is captured. Read the information indicated by codes 2 and 3.

The output unit 65 outputs the information indicated by the two-dimensional codes 2 and 3 read by the reading unit 64 to the control unit 50 of the automatic ticket gate 5.

Next, the operation of the ticket gate processing in the automatic ticket gate 5 will be described. In this example, on the surface of the ticket 1, a two-dimensional code 2 indicating the ticket information and a covering portion 11 covering a part of the two-dimensional code 2 shown in FIG. 5 are formed. Further, a two-dimensional code 3 indicating that the ticket 1 is the back surface is formed on the back surface of the ticket 1, but the covering portion 12 shown in FIGS. 6 (A), (B), and (C) is formed. It may or may not be formed.

As described above, in the ticket 1, a part of the two-dimensional code 2 indicating the ticket information is covered by the covering portion 11, so that the two-dimensional code 2 is prevented from being illegally duplicated by copying or the like. it can. That is, it is possible to prevent the two-dimensional code 2 illegally duplicated by copying or the like from being illegally used as a ticket.

FIG. 10 is a flowchart showing the ticket gate processing in the automatic ticket gate. The automatic ticket gate 5 reads the two-dimensional codes 2 and 3 in the reading unit 51 (51a, 51b) (s1). The details of the two-dimensional code reading process related to s1 will be described later. When the reading unit 51 reads the ticket information indicated by the two-dimensional code 2 in s1, the reading unit 51 outputs the ticket information read this time to the control unit 50. Further, when the reading unit 51 reads the information indicating that the back surface is the back surface indicated by the two-dimensional code 3 in s1, it outputs to the control unit 50 that the back surface of the ticket 1 is held in the reading area.

When the ticket information is input from the reading unit 51 (s2), the control unit 50 determines whether or not the user can pass through the ticket gate passage using the input ticket information (s3). As with the known automatic ticket gates, the passability determination in s3 is performed based on the valid period, valid section, etc. of the ticket 1.

When the control unit 50 determines in the passability determination in s3 that the passage of the user in the ticket gate passage is not permitted, the control unit 50 closes the door located on the exit side of the ticket gate passage for this user (s4, s6), and s1 Return to. Further, when the control unit 50 determines that the passage of the user in the ticket gate passage is permitted in the passability determination in s3, the control unit 50 opens the door located on the exit side of the ticket gate passage for this user (s4, s5). Return to s1. Further, in s5, if it is necessary to collect the ticket 1 from the user, the shutter provided at the ticket collection port 53a is temporarily opened, and after accepting the user to insert the ticket 1, this shutter is used. Close.

Further, if the control unit 50 inputs not the ticket information that is input from the reading unit 51 in s2 but the back side of the ticket 1 that is held in the reading area, the control unit 50 informs the user. Guidance is given to urge the opposite side of the ticket 1 to be held in the reading area (s2, s7), and the ticket returns to s1. In s7, the display unit 55 may display a guidance message on the display or guide by voice message.

In FIG. 10, the process when the ticket is an IC card is omitted. The processing when the ticket is an IC card is the same as that of a known automatic ticket gate, and thus the description thereof will be omitted here.

Next, the two-dimensional code reading process related to s1 will be described. FIG. 11 is a flowchart showing a two-dimensional code reading process. The reading unit 51 executes this two-dimensional code reading process. The control unit 60 determines whether or not a certain time (about 50 msec to 100 msec) or more has elapsed since the previous execution of the process of s12 (s11). The control unit 60 performs the first imaging process when a certain period of time or more has elapsed from the execution of the previous process of s12 (s12). In this first imaging process, the imaging unit 63 is in a state where the visible light emitted by the first irradiation unit 61 to the reading region is turned off and the infrared light emitted by the second irradiation unit 62 to the reading region is turned on. Is the process of imaging the reading area. In s12, if the ticket 1 is held in the reading area, the two-dimensional codes 2 and 3 are imaged by the imaging unit 63 regardless of whether the held surface is the front surface or the back surface, and the reading area is covered. If the ticket 1 is not held, the two-dimensional codes 2 and 3 are not imaged by the imaging unit 63.

The reading unit 64 detects whether or not a two-dimensional code is captured in the image captured by the imaging unit 63 in s12, and if the two-dimensional code is captured, reads the information indicated by the two-dimensional code (s13). ). In s13, if the imaging unit 63 can detect the three symbols of the two-dimensional code from the image captured in s12, it is determined that the two-dimensional code is captured. In other words, in s13, if the imaging unit 63 cannot detect the three symbols of the two-dimensional code from the image captured in s12, the two-dimensional code is not imaged (the ticket 1 is not held in the reading area). Is determined.

The control unit 60 returns to s11 if the two-dimensional code is not captured in the image captured this time by the imaging unit 63 in s12.

When the two-dimensional code is captured in the image captured this time by the imaging unit 63 in s12, the control unit 60 determines whether the information indicated by the two-dimensional code is information indicating that it is the back surface of the ticket 1. Is determined (s14). That is, the control unit 60 determines whether or not the two-dimensional code 3 is captured in the image captured this time by the imaging unit 63 in s12.

When the control unit 60 determines in s14 that the information indicates that it is the back surface of the ticket 1, the output unit 65 outputs that fact to the control unit 50 of the automatic ticket gate 5 (s20) and returns to s11. .. When the control unit 50 of the automatic ticket gate 5 receives an input from the reading unit 51 that the back side of the ticket 1 is held in the reading area, the control unit 50 performs the process related to s7 described above.

Further, if the control unit 60 determines in s14 that the information does not indicate that it is the back surface of the ticket 1, the control unit 60 performs a second imaging process (s15). In this second imaging process, the imaging unit 63 is in a state where the first irradiation unit 61 turns on the visible light irradiating the reading area and the second irradiation unit 62 turns off the infrared light irradiating the reading area. Is the process of imaging the reading area. In s15, even if the ticket 1 is held in the reading area (whether the held surface is the front surface or the back surface), the reading unit 64 reads the information indicated by the two-dimensional codes 2 and 3. I can't.

When the reading unit 64 processes the image captured this time by the imaging unit 63 in s15 and can read the information indicated by the two-dimensional code (s16), the one held in the reading area this time is copied or the like. It is determined that a ticket that has been illegally duplicated or a ticket that is not a ticket has been held, and the process returns to s11. That is, the processes related to s15 and s16 are executed in order to ensure security against the use of the ticket illegally duplicated by copying or the like.

Further, the control unit 60 processes the image captured this time by the imaging unit 63 in s15 by the reading unit 64, and if the information indicated by the two-dimensional code cannot be read, executes the first imaging process again (s17). .. s17 is the same process as s12 described above. When the reading unit 51 reads the information indicated by the two-dimensional code from the image captured by the imaging unit 63 in s17 (s18), the control unit of the automatic ticket gate 5 uses the information indicated by the two-dimensional code read this time as ticket information. Output to 50 (s19) and return to s11. When the ticket information is input from the reading unit 51, the automatic ticket gate 5 performs the processing related to s3 to s6 described above.

In this way, by executing the processes related to s15 and s16 in the two-dimensional code reading process, it is possible to prevent the illegally duplicated ticket from being used by copying or the like.

Further, when the user mistakenly holds the back surface of the ticket 1 over the reading area, the user can be guided to hold the opposite surface (front surface) of the ticket 1.

Further, since the two-dimensional code 3 which is difficult for the user to see is formed on the back surface of the ticket 1, it is possible to suppress an increase in the number of users who misidentify the surface of the ticket 1 to be held in the reading area.

The processing related to s17 and s18 is eliminated, and in s19, the information indicated by the two-dimensional code captured in the image captured by the imaging unit 63 in s12 is output to the control unit 50 of the automatic ticket gate 5 as ticket information. You may. In this example, in the processing related to s17 and s18, the ticket illegally duplicated by copying or the like is held in the reading area in the first imaging process of s12, and is out of the reading area in the second imaging process of s15. It is provided to prevent erroneous determination that the ticket 1 is appropriate when it is moved.

Further, the two-dimensional code reading process shown in FIG. 11 may be replaced with the process shown in FIG. The processing of s31 to s33 shown in FIG. 12 is the same as that of s11 to s13 shown in FIG.

When the control unit 60 of the reading unit 51 can read the information indicated by the two-dimensional code detected in s33, the control unit 60 executes the processes related to s34 to s37. The processing for s34 to s37 is the same as that for s15 to s18 shown in FIG. That is, the reading unit 51 according to this example does not execute the above-described processing related to s14 between s33 and s34.

Further, when the control unit 60 can read the information indicated by the two-dimensional code detected in s37 by the reading unit 64, it is information indicating that the read information is the back surface of the ticket 1, or the ticket. It is determined whether it is information (s38). s38 is the same process as s14 shown in FIG. When the control unit 60 determines in s38 that the information indicates the back surface, it outputs that fact to the control unit 50 of the automatic ticket gate 5 (s40) and returns to s31.

Further, when the control unit 60 determines in s38 that the ticket information is the ticket information, the control unit 60 outputs the information of the two-dimensional code 2 read this time to the control unit 50 of the automatic ticket gate 5 as the ticket information (s39), and returns to s31. ..

The two-dimensional code reading process shown in FIG. 12 has the same effect as the two-dimensional code reading process shown in FIG. Further, in FIG. 12, the processing related to s32 and s33 may be unnecessary. In this case, the elapsed time from the previous second imaging process on s34 may be determined by s31.

Further, the two-dimensional code reading process may be the process shown in FIG. The processing of s51 to s53 shown in FIG. 13 is the same as that of s11 to s13 shown in FIG. 11 and s31 to s33 shown in FIG.

When the control unit 60 can read the information indicated by the two-dimensional code detected in s53 by the reading unit 64, it is information indicating that the read information is the back surface of the ticket 1, or the ticket information. It is determined whether or not there is (s54). s54 is the same process as s14 shown in FIG. 11 and s38 shown in FIG. When the control unit 60 determines in s54 that the information indicates the back surface, it outputs that fact to the control unit 50 of the automatic ticket gate 5 (s56) and returns to s51.

Further, when the reading unit 51 determines in s54 that it is the ticket information, it outputs the information of the two-dimensional code 2 read this time to the control unit 50 of the automatic ticket gate 5 as the ticket information (s55), and returns to s51. ..

In the process shown in FIG. 13, since the second imaging process described above is not performed, the processing load can be reduced. Further, since the reading unit 51 does not require the first irradiation unit 61, the configuration can be simplified.

Further, in the above example, in the reading unit 51, the captured image of the reading region captured by the imaging unit 63 is processed by the reading unit 64, and the information of the two-dimensional codes 2 and 3 captured in the captured image is read. However, the automatic ticket gate 5 may be configured to process the captured image of the reading region captured by the imaging unit 63 and read the information of the two-dimensional codes 2 and 3 that have been captured (in the present invention). A configuration related to the determination unit may be provided on the automatic ticket gate 5 side.) In this case, the reading unit 51 may output the captured image of the reading region captured by s36 or s52 to the control unit 50 of the automatic ticket gate 5.

Further, in the case of the ticket 1 in which the covering portion 11 is not formed, the reading process of the two-dimensional codes 2 and 3 may be executed by the process shown in FIG.

Further, when the reading unit 51 determines that the back surface of the ticket 1 is held in the reading area, the reading unit 51 may be provided with a configuration for guiding the opposite surface (reading the configuration related to the guide portion referred to in the present invention). It may be provided on the unit 51 side.)

Further, in the above example, although an example in which infrared light is used is shown, ultraviolet light may be used. In this case, the two-dimensional codes 2, 3 and the covering portions 11 and 12 may be determined according to the ultraviolet light using the optical characteristics of the ink.

Further, in the above example, the information medium according to the present invention has been described as a ticket 1, but it can also be applied to uses other than the ticket 1. For example, the information medium may be an ID medium used for entering and exiting the security room. In this case, the information medium processing device according to the present invention is applied to the entry / exit management device.

Further, the information medium according to the present invention is not limited to a sheet-shaped medium or a card-shaped medium, and may have a three-dimensional shape (for example, a hexahedron or an octahedron). In this case, the first information code may be formed on one or more surfaces, and the second information code may be formed on one or more surfaces. However, the first information code and the second information code are not formed on the same surface.

Further, the information medium according to the present invention may be a wristband. In this case, the first information code and the second information code may be formed on the same surface.

Further, the information code is not limited to the two-dimensional code, and may be a one-dimensional bar code or the like, or may be another information symbol.
