The front display unit 133 displays marks, figures, characters, and the like indicating whether or not the passage is possible in the b direction shown in FIG. The display content of the front display unit 133 or the presence or absence of the display is determined by the ticket gate side control unit 150.

When the automatic ticket gate 100 is set to the operation mode that allows the user to pass in the direction a shown in FIG. 3, the ticket gate side control unit 150 keeps the doors 115 and 135 in the open state and at the same time. By controlling the door portions 114 and 134 in the open state or the closed state, the passage of the user in the a direction is permitted or prohibited. Further, the ticket gate side control unit 150 keeps the door portions 114 and 134 in the open state when the automatic ticket gate 100 is set to the operation mode that allows the user to pass in the direction b shown in FIG. At the same time, by controlling the door portions 115 and 135 to be in the open state or the closed state, the passage of the user in the b direction is permitted or prohibited.

Further, the operation mode of the automatic ticket gate 100 may include an operation mode that allows both passage in the a direction and passage in the b direction shown in FIG. In this case, the ticket gate side control unit 150 controls to display, for example, a mark, a figure, a character, or the like indicating that both the front display unit 113 and the front display unit 133 are allowed to pass if the user is not passing. I do. Further, the ticket gate side control unit 150, for example, allows the user to enter from either the a direction or the b direction and display the display object OB on either the optical reading unit 111 or the optical reading unit 131. When the medium is held, the other optical reading unit is invalidated, and a mark indicating that passage is prohibited on the display unit (front display unit 113 or front display unit 133) on the side where the user has not entered is prohibited. Controls the display of optics, figures, characters, etc.

Note that, in FIG. 3, the automatic ticket gate 100 has been described as a dedicated machine for processing a medium for displaying display objects such as a ticket TIX and a terminal device 10, but the present invention is not limited to this, and for example, a magnetic ticket or a transportation IC card. It may be a device capable of processing. Further, the automatic ticket gate 100 is not limited to the one that the user can pass in both directions, but also the one that is composed of the main engine and the auxiliary machine (slave machine) and that the user can pass in only one direction. Good.

FIG. 4 is a view of the optical reading unit 111 of the automatic ticket gate 100 according to the first embodiment as viewed from above. The optical reading unit 111 includes, for example, a protective panel PN, a camera 111a, and a light LT. The protective panel PN is a transparent (or translucent) type panel capable of transmitting visible light, and enables imaging of a display object OB that transmits the protective panel PN. The camera 111a captures a medium (ticket FIX or terminal device 10) held over the protective panel PN. The camera 111a has, for example, an image sensor such as a CCD (Charge-Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor). The light LT irradiates light toward the medium when the camera 111a images the medium. The configuration of the optical reading unit 111 shown in FIG. 4 may be similarly applied to the optical reading unit 131 of the slave machine 130. That is, the optical reading unit 131 of the slave machine 130 may be configured to include a protective panel PN, a camera 131a, and a light LT.

FIG. 5 is a view of the main engine 110 of the automatic ticket gate 100 of the first embodiment as viewed from the aisle side. The main engine 110 further includes a transmission type photoelectric sensor St and a reflection type photoelectric sensor Sr in addition to the above-mentioned optical reading unit 111, door portions 114 and 115 and the like. For example, a plurality of transmissive photoelectric sensors St are provided at equal intervals (26 in the case of the example of FIG. 4) on the housing surface on the passage side of the housing surface of the main engine 110. In the present embodiment, a transmissive photoelectric sensor St that functions as a floodlight and a transmissive photoelectric sensor St that functions as a receiver are used as a pair.

For example, when the transmissive photoelectric sensor St provided on the main engine 110 is a floodlight, the transmissive photoelectric sensor St provided on the slave 130 side functions as a receiver. The ticket gate side control unit 150, which will be described later, identifies the position in the passage based on the detection signals of the plurality of transmissive photoelectric sensors St and the arrangement positions of the transmissive photoelectric sensors St. .. Further, similarly to the transmissive photoelectric sensor St, a plurality of reflective photoelectric sensors Sr are provided at equal intervals on the passage-side surface of the partition portion protruding upward from the housing of the main engine 110 (in the example of FIG. 5). In the case, 3) will be provided. The reflective photoelectric sensor Sr projects light in a predetermined direction. After projecting light, the reflective photoelectric sensor Sr receives light incident from the projected direction. The reflective photoelectric sensor Sr generates a detection signal indicating whether or not a user's body that reflects light is present in the passage based on the intensity of the received light. The reflective photoelectric sensor Sr is mainly used to identify the height of a user existing in the passage. Although the above-mentioned reflection type photoelectric sensor Sr has been described as being provided in the main engine 110, the present invention is not limited to this, and the reflection type photoelectric sensor Sr may be provided in the slave unit 130, or may be provided in both the main engine 110 and the slave unit 130. Good.

[Functional configuration of automatic ticket gates]
FIG. 6 is a diagram showing an example of the functional configuration of the automatic ticket gate 100 according to the first embodiment. In addition to the configuration shown in FIG. 3, the automatic ticket gate 100 further includes a speaker 140 that outputs sound according to an instruction from the ticket gate side control unit 150, and a ticket gate side storage unit 170 that stores various information.

The optical reading unit 111 on the main engine 110 side includes a camera 111a and an image processing unit 111b. Similarly, the optical reading unit 131 on the slave unit 130 side includes a camera 131a and an image processing unit 131b. For example, the image processing units 111b and 131b extract the finder pattern FP from the images captured by the corresponding cameras, and specify the position of the main pattern MP on the image based on the positional relationship of the plurality of finder pattern FPs. To do. The image processing units 111b and 131b decode the position-specified main pattern MP and convert it into computer-recognizable object data represented by a bit string or the like. As described above, since the main pattern MP _{includes the image areas of the unique codes FP-ID A} and FP-ID _B , the object data converted from the main pattern MP includes the unique codes FP-ID _A and FP. -ID _B will be included. Then, the image processing units 111b and 131b output the converted object data to the ticket gate side control unit 150.

The ticket gate side control unit 150 includes an acquisition unit 152, a first determination unit 154, a second determination unit 156, and a passage control unit 158. A part or all of these components may be realized by executing a program stored in the ticket gate side storage unit 170 by a processor such as a CPU (Central Processing Unit). Further, even if some or all of the components of the ticket gate side control unit 150 are realized by hardware such as LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), and FPGA (Field-Programmable Gate Array). It may be realized by the collaboration of software and hardware.

The ticket gate side storage unit 170 uses, for example, a ROM (Read Only Memory), a flash memory, an HDD (Hard Disk Drive), an SD card, an MRAM (Magnetoresistive Random Access Memory), a RAM (Random Access Memory), a register, or the like. It may be realized. The ticket gate side storage unit 170 stores a program executed by the processor and also stores a fare table 172 and the like.

The acquisition unit 152 acquires object data from the image processing unit 111b or the image processing unit 131b.

FIG. 7 is a diagram showing an example of object data. In the figure (a), an example of the data structure of the object data converted from the first display object OB is shown. For example, since the first display object OB includes the finder pattern FP, the main pattern MP, and the unique codes FP-ID _A and FP-ID _B , the object data converted from the first display object OB. Includes two-dimensional code data in which the main pattern MP, which is an image, is converted into data, and unique codes FP-ID _A and FP-ID _B. The two-dimensional code data includes, for example, efficacy information. The object data converted from the first display object OB includes various control codes such as STX (Start of TeXt) attached to the beginning of the data and ETX (End of TeXt) attached to the end of the data. Good. The two-dimensional code data is an example of information of either "first information" or "second information", and the unique codes FP-ID _A and FP-ID _B are "first information" and "second information". It is an example of the information of either one or the other of "information". The main pattern MP is an example of a "predetermined area".

Further, (b) in the figure shows an example of the data structure of the object data converted from the second display object OB. As described above, since the second display object OB _{does not include the unique code FP-ID A} and FP-ID _B , the object data converted from the second display object OB is the unique code FP-ID _A and Includes two-dimensional code data and various control codes such as STX and ETX, excluding FP-ID _B.

The first determination unit 154 is held by the automatic ticket gate 100 based on the presence / absence of the two-dimensional code data and the unique codes FP-ID _A and FP-ID _{B included in the object data acquired by the acquisition unit 152.} Determine if the medium has been abused.

FIG. 8 is a diagram showing an example of a determination result by the first determination unit 154 according to each condition. For example, the first determination unit 154 determines that the medium has been properly used when the object data contains the two-dimensional code data and the unique codes FP-ID _A and FP-ID _{B (No. in the figure).} See the record in 1).

Further, when the object data includes the two-dimensional code data and the unique codes FP-ID _A and FP-ID _B do not exist, the first determination unit 154 adds the content of the effect information included in the two-dimensional code data. Based on this, it is determined whether or not the medium held in the automatic ticket gate 100 has been illegally used.

For example, if the content of the validity information is not "contents related to ticket gates", the first determination unit 154 determines that the information has been legally used (see the record No. 2 in the figure), and the content of the validity information is "contents related to ticket gates". If it is, it is determined that the record has been abused (see the record No. 3 in the figure). For example, when the validity information includes a part or all of the validity period, the boarding station, the boarding section, the ticket identification information, the boarding time, and the entry / exit information, the first judgment unit 154 states that "contents related to ticket gates". It is determined that it is. The case where the content of the validity information is not "content related to the ticket gate" is, for example, the case where the medium is used as a facility admission ticket. The content related to ticket gates is an example of "predetermined content".

For example, in order to use a store in a station, by registering an e-mail address on the website of this store, a display object OB that can temporarily enter the station premises may be issued via e-mail or the like. is there. In this case, the user enters the station yard by displaying the issued display object OB on the screen of the terminal device 10. This admission-only display object OB is issued as a second display object OB that does not include _{the unique codes FP-ID A} and FP-ID _B. In addition, the display object OB dedicated to admission includes validity information as specified by the admission station, and the validity information for determining "contents related to ticket gates" is omitted. As a result, the first determination unit 154 determines that the display object OB dedicated to admission is simply used, and is not the display object OB dedicated to admission, but the unique code FP-ID _A. And when the _{display object OB in which FP-ID B} does not exist is held, it is determined that this is an unauthorized use.

Further, when the object data does not have the two-dimensional code data and the unique codes FP-ID _A and FP-ID _B exist in the object data, the first determination unit 154 needs to guide the object data to hold the medium again. (Refer to the record No. 4 in the figure).

Further, when the two-dimensional code data does not exist in the object data and the unique codes FP-ID _A and FP-ID _B do not exist in the object data, the first determination unit 154 causes some abnormality when reading the display object OB. It is determined that the data is displayed, or that it is necessary to guide the user to hold the medium again (see the record No. 5 in the figure).

The second determination unit 156 determines whether or not the user who holds the medium in the optical reading units 111 and 131 can pass through, based on the determination result by the first determination unit 154. When the first determination unit 154 determines that the medium has been legally used, the second determination unit 156 determines whether or not the medium can be passed based on the effect information included in the two-dimensional code data.

For example, the second determination unit 156 installed the automatic ticket gate 100, which is its own device, by collating the information such as the validity period of the validity information, the boarding station (departure station), and the boarding section with the fare table 172. Whether or not the station and the boarding station match, whether or not the station where the automatic ticket gate 100 is installed is within the boarding section, and whether or not the boarding section of the user at the participating station is commensurate with the purchase price at the time of the ticket. , Judgment is made for some or all of the conditions such as whether or not the time when the medium is held by the optical reading units 111 and 131 is within the valid period, and if all the judgment conditions are satisfied, the passage of the user is permitted. However, if any one or more of the judgment conditions are not satisfied, the passage of the user is prohibited.

In addition, the second determination unit 156 prohibits the passage of the user when the first determination unit 154 determines that the medium has been illegally used. In addition, the second determination unit 156 prohibits the user from passing when the first determination unit 154 determines that re-holding guidance is necessary. In addition, the second determination unit 156 prohibits the user from passing when the first determination unit 154 determines that an abnormality has occurred during reading.

The passage control unit 158 may use the door units 114, 115, 134, 135, the speaker 140, the top display units 112, 132, the front display units 113, 133, or the door units 114, 115, 134, 135, depending on the determination result of whether or not the passage is possible by the second determination unit 156. By controlling a combination of these, the passage of the user is controlled.

[Processing flow of automatic ticket gate]
Hereinafter, a series of processing flows by the ticket gate side control unit 150 in the first embodiment will be described. FIG. 9 is a flowchart showing a flow of a series of processes by the ticket gate side control unit 150 in the first embodiment. The processing of this flowchart is, for example, repeated at a predetermined cycle.

First, the first determination unit 154 determines whether or not the object data has been acquired from the optical reading units 111 and 131 by the acquisition unit 152 (step S100). When the acquisition unit 152 determines that the object data has not been acquired from the optical reading units 111 and 131, the second determination unit 156 is based on the detection signals output by the transmission type photoelectric sensor St and the reflection type photoelectric sensor Sr. Then, it is determined whether or not the user has reached a predetermined position in the passage (step S102). The predetermined position is, for example, near the middle of the passage as seen from the traveling direction of the user. That is, the second determination unit 156 determines whether or not the user has invaded the passage in a state where the display object OB cannot be read by the optical reading units 111 and 131.

When it is determined that the user has reached a predetermined position in the passage, the second determination unit 156 prohibits the user from passing through. In response to this, the passage control unit 158 causes, for example, the top display unit 112 (132), the front display unit 113 (133), and / or the speaker 140 to output information indicating that the information cannot be read from the medium, and the door. Units 114 (115) and 134 (135) are controlled to be closed to prohibit the passage of the user (step S104).

On the other hand, when it is determined by the acquisition unit 152 that the object data has been acquired from the optical reading units 111 and 131, the first determination unit 154 determines whether or not the object data includes the two-dimensional code data (step S106). ). When the object data includes the two-dimensional code data, the first determination unit 154 further _{determines whether or not the object data includes the unique codes FP-ID A} and FP-ID _B (step S108). ).

When the object data does not include the unique codes FP-ID _A and FP-ID _B , the first determination unit 154 determines whether or not the content of the validity information included in the two-dimensional code data is "contents related to ticket gates". (Step S110). When the content of the validity information is "content related to the ticket gate", the first determination unit 154 determines that the held medium has been illegally used (step S112). Then, as the process of S104, the passage control unit 158 outputs information indicating that the held medium cannot be used to, for example, the upper surface display unit 112 (132), the front display unit 113 (133), and / or the speaker 140. The door portions 114 (115) and 134 (135) are controlled to be closed to prohibit the passage of the user. As a result, if the original information cannot be read, it is suspected that the display object OB or the ticket TIX itself on which the display object OB is printed has been forged, and thus the passage of users using this medium is restricted. be able to.

FIG. 10 is a diagram showing an example of a screen to be displayed on the upper surface display units 112 and 132 when it is determined that the product has been illegally used. As shown in the figure, for example, on the screens of the upper surface display units 112 and 132, it is displayed in characters or the like that the held ticket TIX cannot be used.

On the other hand, if the object data includes the unique codes FP-ID _A and FP-ID _B , or if the content of the validity information included in the two-dimensional code data is not "contents related to ticket gates", the first determination unit 154 Determines that the held medium has been legitimately used (step S114). In response to this, the second determination unit 156 determines whether or not the passage is possible based on the effect information included in the two-dimensional code data. In this flowchart, as an example, it is assumed that the passage of the user is permitted by the second determination unit 156. In this case, the passage control unit 158 causes, for example, the top display unit 112 (132), the front display unit 113 (133), and / or the speaker 140 to output information indicating that the information has been read from the medium, and the door unit 114. (115) and 134 (135) are controlled to be in the open state to allow the user to pass through (step S116).

On the other hand, when the object data does not include the two-dimensional code data, the first determination unit 154 determines whether or not _{the object data includes the unique codes FP-ID A} and FP-ID _{B, as in the process of S108.} Is determined (step S118).

When the object data includes the unique codes FP-ID _A and FP-ID _B , the first determination unit 154 determines that it is necessary to guide the user to hold the medium again (step S120). In response to this, the passage control unit 158 causes, for example, the top display unit 112 (132), the front display unit 113 (133), and / or the speaker 140 to output information prompting the medium to be held again (step S122). ). At this time, the passage control unit 158 may control the door units 114 (115) and 134 (135) in the closed state or in the open state.

FIG. 11 is a diagram showing another example of a screen to be displayed on the upper surface display units 112 and 132 when it is determined that the product has been abused. As shown in the figure, for example, on the screens of the upper surface display units 112 and 132, it is displayed in characters or the like that information cannot be read from the ticket TIX held up.

On the other hand, when the object data _{does not include the unique codes FP-ID A} and FP-ID _B , the first determination unit 154 determines that an abnormality has occurred during reading (step S124). In response to this, the passage control unit 158 causes, for example, the top display unit 112 (132), the front display unit 113 (133), and / or the speaker 140 to output information indicating that the automatic ticket gate 100 cannot be used. The door portions 114 (115) and 134 (135) are controlled to be in the closed state to prohibit the passage of the user (step S126). It should be noted that the passage control unit 158 may perform the processing of S122 when the first determination unit 154 determines that an abnormality has occurred during reading, as in the case where it is determined that re-holding guidance is necessary. Good. This completes the processing of this flowchart.

According to the first embodiment described above, acquisition of object data from optical reading units 111 and 131 that optically read information from a display object OB displayed on a medium such as a ticket TIX or a terminal device 10. It is determined whether or not the medium has been illegally used based on the presence or absence of the two-dimensional code data in the object data acquired by the unit 152 and the acquisition unit 152, and the unique codes FP-ID _A and FP-ID _{B, respectively.} It is determined that the data is illegally used by providing the first determination unit 154 and the second determination unit 156 that determines whether or not the user holding the medium can pass through based on the determination result by the first determination unit 154. If so, the passage of users is prohibited. As a result, unauthorized passage can be prevented.

(Second embodiment)
Hereinafter, the second embodiment will be described. In the second embodiment, one of the unique code FP-ID _A and the unique code FP-ID _B is encrypted (encrypted) using the other as an encryption key, and the automatic ticket gate 100A is used as object data. Whether or not the medium has been abused based on the value of the decrypted code after decoding (decrypting) one of the included unique code FP-ID _A and unique code FP-ID _{B with the other code.} It differs from the first embodiment in that it determines whether or not. Hereinafter, the differences from the first embodiment will be mainly described, and the points common to the first embodiment will be omitted. In the description of the second embodiment, the same parts as those of the first embodiment will be described with the same reference numerals.

FIG. 12 is a diagram showing an example of the functional configuration of the automatic ticket gate 100A according to the second embodiment. The ticket gate side control unit 150A of the automatic ticket gate 100A in the second embodiment further includes a decoding processing unit in addition to the acquisition unit 152, the first determination unit 154, the second determination unit 156, and the passage control unit 158 described above. 160 is provided.

_{When the unique codes FP-ID A} and FP-ID _B are present in the object data acquired by the acquisition unit 152, the decoding processing unit 160 uses one code to decode the other code. In the present embodiment, as an example, it is assumed that the unique code FP-ID _B is encrypted using _{the unique code FP-ID A as an encryption key.} Therefore, the decoding processing unit 160, using the unique code FP-ID _A, to decode the unique code FP-ID _B. For example, the decryption processing unit 160 uses _{a decryption method corresponding to the encryption method used when encrypting the unique code FP-ID B} (for example, a common key encryption method such as stream cipher or a public key encryption method such as RSA encryption). It may be used to decode the unique code FP-ID _B. In addition to the unique code FP-ID _A or FP-ID _B , the two-dimensional code data may also be encrypted. In this case, the decryption processing unit 160 may decrypt the two-dimensional code data by using the other unique code as the encryption key.

The first determination unit 154 in the second embodiment uses the medium illegally based on the presence / absence of the _{unique code FP-ID A} and the unique code FP-ID _{B included in the object data and the value of the code.} Determine if it has been done.

FIG. 13 is a diagram showing another example of the determination result by the first determination unit 154 according to each condition. For example, the first determination unit 154 has the two-dimensional code data and the unique code FP-ID _A and FP-ID _B in the object data, and the unique code FP-ID decoded by using the _{unique code FP-ID A. When} the value of B is a predetermined value, it is determined that the medium held in the automatic ticket gate 100 has been legally used (see the record No. 1 in the figure).

Further, the first determination unit 154 determines that the medium has been illegally used when the value of the unique code FP-ID _{B decoded by using the unique code FP-ID A} is not a predetermined value (No. 2 in the figure). See record).

Further, the first determination unit 154 is included in the two-dimensional code data when the two-dimensional code data exists in the object data, the unique code FP-ID _A does not exist, and the unique code FP-ID _B cannot be decoded. Based on the content of the validity information, it is determined whether or not the medium held in the automatic ticket gate 100 has been illegally used.

For example, if the content of the validity information is not "contents related to ticket gates", the first judgment unit 154 determines that the information has been legally used (see the record No. 3 in the figure), and the content of the validity information is "contents related to ticket gates". If it is, it is determined that the record has been abused (see the record No. 4 in the figure).

The first determination unit 154, the object data, there is no two-dimensional code data, and when the unique code FP-ID _A and FP-ID _B is present, using the unique code FP-ID _A unique If the code FP-ID _B is not decoded, it is determined that it is necessary to guide the user to hold the medium again (see the record No. 5 in the figure).

Further, the first determination unit 154 determines that some abnormality has occurred when reading the display object OB when the two-dimensional code data does not exist in the object data and the unique code FP-ID _{A does not exist.} Or, it is determined that it is necessary to guide the user to hold the medium again (see the record No. 6 in the figure).

Hereinafter, a series of processing flows by the ticket gate side control unit 150A in the second embodiment will be described. FIG. 14 is a flowchart showing a flow of a series of processes by the ticket gate side control unit 150A in the second embodiment. The processing of this flowchart is, for example, repeated at a predetermined cycle.

First, the first determination unit 154 determines whether or not the object data has been acquired from the optical reading units 111 and 131 by the acquisition unit 152 (step S200). When the acquisition unit 152 determines that the object data has not been acquired from the optical reading units 111 and 131, the second determination unit 156 is based on the detection signals output by the transmission type photoelectric sensor St and the reflection type photoelectric sensor Sr. Then, it is determined whether or not the user has reached a predetermined position in the passage (step S202).

When it is determined that the user has reached a predetermined position in the passage, the second determination unit 156 prohibits the user from passing through. In response to this, the passage control unit 158 causes, for example, the top display unit 112 (132), the front display unit 113 (133), and / or the speaker 140 to output information indicating that the information cannot be read from the medium, and the door. Units 114 (115) and 134 (135) are controlled to be closed to prohibit the passage of the user (step S204).

On the other hand, when it is determined by the acquisition unit 152 that the object data has been acquired from the optical reading units 111 and 131, the first determination unit 154 determines whether or not the object data includes the two-dimensional code data (step S206). ). When the object data includes the two-dimensional code data, the first determination unit 154 further _{determines whether or not the object data includes the unique code FP-ID A} (step S208).

When the object data does not include the unique code FP-ID _A , the first determination unit 154 determines whether or not the content of the validity information included in the two-dimensional code data is "content related to ticket gates" ( Step S210). When the content of the validity information is "content related to the ticket gate", the first determination unit 154 determines that the held medium has been illegally used (step S212). Then, as the process of S204, the passage control unit 158 outputs information indicating that the held medium cannot be used to, for example, the upper surface display unit 112 (132), the front display unit 113 (133), and / or the speaker 140. The door portions 114 (115) and 134 (135) are controlled to be closed to prohibit the passage of the user.

On the other hand, when the object data includes the unique code FP-ID _A , the first determination unit 154 includes the unique code FP-ID _{B in} the object data and the unique code FP decoded by the decoding processing unit 160. -It _{is determined whether or not the value of ID B} is a predetermined value (step S214).

_{When the value of the unique code FP-ID B} decoded by the decoding processing unit 160 is not a predetermined value, the first determination unit 154 shifts to the processing of S212 and determines that the held medium has been illegally used.

_{On the other hand, if the value of the unique code FP-ID B} decoded by the decoding processing unit 160 is a predetermined value, or if the content of the validity information included in the two-dimensional code data is not "content related to ticket gates", the first determination is made. Unit 154 determines that the held medium has been legitimately used (step S216). In response to this, the second determination unit 156 determines whether or not the passage is possible based on the effect information included in the two-dimensional code data. In this flowchart, as an example, it is assumed that the passage of the user is permitted by the second determination unit 156. In this case, the passage control unit 158 causes, for example, the top display unit 112 (132), the front display unit 113 (133), and / or the speaker 140 to output information indicating that the information has been read from the medium, and the door unit 114. (115) and 134 (135) are controlled to be in the open state to allow the user to pass through (step S218).

On the other hand, when the object data does not include the two-dimensional code data, the first determination unit 154 determines whether or not _{the object data includes the unique code FP-ID A, as in the process of S208 (step).} S220).

When the object data includes the unique code FP-ID _A , the first determination unit 154 determines that it is necessary to guide the user to hold the medium again (step S222). In response to this, the passage control unit 158 causes, for example, the top display unit 112 (132), the front display unit 113 (133), and / or the speaker 140 to output information prompting the medium to be held again (step S224). ). At this time, the passage control unit 158 may control the door units 114 (115) and 134 (135) in the closed state or in the open state.

On the other hand, when the object data _{does not include the unique code FP-ID A} , the first determination unit 154 determines that an abnormality has occurred during reading (step S226). In response to this, the passage control unit 158 causes, for example, the top display unit 112 (132), the front display unit 113 (133), and / or the speaker 140 to output information indicating that the automatic ticket gate 100 cannot be used. The door portions 114 (115) and 134 (135) are controlled to be closed to prohibit the passage of the user (step S228). It should be noted that the passage control unit 158 may perform the processing of S224 when the first determination unit 154 determines that an abnormality has occurred during reading, as in the case where it is determined that re-holding guidance is necessary. Good. This completes the processing of this flowchart.

According to the second embodiment described above, unauthorized passage can be prevented as in the first embodiment described above.

Further, according to the second embodiment described above, unauthorized passage is prevented more accurately by decrypting the other code encrypted by using one of _{the unique codes FP-ID A} and FP-ID _B. can do.

(Modified example of the second embodiment)
Hereinafter, a modified example of the second embodiment will be described. In the modified example of the second embodiment, the authentication code is embedded as a pattern in the display object OB. The authentication code is provided, for example, as one or more codes forming the main pattern MP, in addition to the unique codes FP-ID _A and FP-ID _B. The authentication code is an example of "third information".

FIG. 15 is a diagram showing another example of object data. The object data shown in the figure is data converted from the first display object OB including the authentication code. As shown in the figure, when converted from the first display object OB including the authentication code, the object data includes the authentication code. This authentication code may be encrypted using either one of the unique codes FP-ID _A and FP-ID _{B as an encryption key.} In the present embodiment, as an example, it is assumed that the unique code FP-ID _A and the unique code FP-ID _B are the same code, and both the unique code FP-ID _A and the unique code FP-ID _B are authentication codes. Will be described as being able to decode.

When the object data acquired by the acquisition unit 152 includes the two-dimensional code data and the unique codes FP-ID _A and FP-ID _B , the decoding processing unit 160 in the modified example of the second embodiment has the unique code FP. -At _{least one of the codes A} and FP-ID _B is used to decrypt the authentication code contained in the two-dimensional code data.

When the authentication code is decrypted by the decryption processing unit 160, the first determination unit 154 in the modified example of the second embodiment legitimately uses the held medium based on the value of the decrypted authentication code. Determine if it is. For example, the first determination unit 154 determines that the decrypted medium is properly used when the value of the decrypted authentication code is a predetermined value, and when the value of the decrypted authentication code is not a predetermined value, the first determination unit 154 determines. It is determined that the held medium has been misused.

FIG. 16 is a diagram showing another example of the determination result by the first determination unit 154 according to each condition. For example, the first determination unit 154 in the modified example of the second embodiment has two-dimensional code data and unique codes FP-ID _A and FP-ID _B in the object data, and uses either one of the unique codes. When the value of the decrypted authentication code is a predetermined value, it is determined that the held medium has been legally used (see the record No. 1 in the figure).

Further, the first determination unit 154 determines that the medium has been illegally used when the value of the authentication code decrypted using either one of the unique codes is not a predetermined value (see the record No. 2 in the figure). ..

Further, when the object data has the two-dimensional code data and the unique codes FP-ID _A and FP-ID _B do not exist and the authentication code cannot be decrypted, the first determination unit 154 converts the two-dimensional code data into the two-dimensional code data. Based on the content of the included validity information, it is determined whether or not the held medium has been misused.

For example, if the content of the validity information is not "contents related to ticket gates", the first judgment unit 154 determines that the information has been legally used (see the record No. 3 in the figure), and the content of the validity information is "contents related to ticket gates". If it is, it is determined that the record has been abused (see the record No. 4 in the figure).

Further, the first determination unit 154 guides the object data to hold the medium again when the two-dimensional code data does not exist and the unique codes FP-ID _A and FP-ID _{B exist.} It is determined that it is necessary (see the record No. 5 in the figure).

Further, when the two-dimensional code data does not exist in the object data and the unique codes FP-ID _A and FP-ID _B do not exist in the object data, the first determination unit 154 causes some abnormality when reading the display object OB. It is determined that the data is displayed, or that it is necessary to guide the user to hold the medium again (see the record No. 6 in the figure).

As a result, it is possible to prevent unauthorized passage more accurately, as in the second embodiment described above.

According to at least one embodiment described above, acquisition of object data from optical reading units 111 and 131 that optically read information from a display object OB displayed on a medium such as a ticket TIX or a terminal device 10. It is determined whether or not the medium has been illegally used based on the presence or absence of the two-dimensional code data in the object data acquired by the unit 152 and the acquisition unit 152, and the unique codes FP-ID _A and FP-ID _{B, respectively.} It is determined that the data is illegally used by providing the first determination unit 154 and the second determination unit 156 that determines whether or not the user holding the medium can pass through based on the determination result by the first determination unit 154. If so, the passage of users is prohibited. As a result, unauthorized passage can be prevented.
