Description

[Technical field]

[0001] An embodiment of the present invention relates to a ticket gate and a ticket gate program. [Background technology]

[0002] The ticket gate can read the media information from the medium containing the 2D code and determine whether or not the passenger can pass through. If the medium is removed from the media information reading section before the media information is read, the ticket gate will not allow the passenger to pass through. Also, if the medium that was used to allow passage once is held up again within a certain period of time, the ticket gate will not react because it will read the same media information (preventing double reading).

[0003] Furthermore, for example, Patent Document 1 proposes a technique of using a passage sensor installed in a ticket gate when determining whether or not a passenger holding a medium is the same person. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2016-057830 A Summary of the Invention [Problem to be solved by the invention]

[0005] If a passenger who has once been allowed to pass holds the medium over the medium information reading section again but then removes it immediately, the ticket gate may detect the medium but not be able to read the medium information. Similarly, if a passenger who has once been allowed to pass continues to hold the medium over the medium information reading section but then removes the medium from the medium information reading section, the ticket gate may detect the medium but not be able to read the medium information. In these cases, because the medium information of the medium that was held over again cannot be read, the ticket gate cannot determine whether the medium that was allowed to pass and the medium that it detected are the same. This creates the problem that the ticket gate will not allow a passenger who was once allowed to pass to pass, and so the passenger will not be able to pass.

[0006] This invention has been made in light of the above-mentioned circumstances, and its purpose is to provide technology that can determine that a medium held up a second time is the same as the medium held up the first time and not react, even if the medium information on the medium cannot be read, thereby preventing double reading. [Means for solving the problem]

[0007] The ticket gate of the embodiment is configured to include a media information acquisition control unit that allows a first passenger to pass based on first media information of a first medium carried by the first passenger, and then receives media detection information indicating that a second medium carried by a second passenger has been detected, and receives media information not acquired information indicating that the second media information of the second medium could not be read, and a passability determination unit that acquires passenger information about the second passenger based on the media information not acquired information, and determines whether the second medium is the same as the first medium based on the passenger information.

[0009] The ticket gate and the ticket gate program will be described in detail below with reference to the drawings. In the following embodiment, the same numbered parts perform the same operation, and the description will be omitted. For example, when there are a plurality of identical or similar elements, a common symbol may be used to describe each element without distinguishing between them, and a subnumber may be used in addition to the common symbol to describe each element with distinction between them.

[0010] FIG. 1 is a conceptual diagram showing an example of the configuration of a ticket gate system 1 according to an embodiment. The ticket gate system 1 is, for example, a system for controlling entry and exit at ticket gates in transportation facilities such as trains or buses. In addition, the ticket gate system 1 can of course also be applied to entry and exit at live music venues and the like.

[0011] As shown in FIG. 1, the ticket gate system 1 includes a ticket gate 2, a medium information reading unit 31, a door 32, and the like.

[0012] The ticket gate 2 controls whether or not to permit passage of a passenger (user) who is attempting to pass through (enter or exit) a passageway. One or more ticket gates 2 may be installed at ticket gates of a station or the like. Each of these ticket gates 2 forms a passageway through which passengers can pass. The ticket gates 2 may be connectable to other devices such as a central server via a network, either wired or wirelessly.

[0013] The medium information reading unit 31 is installed on the ticket gate 2 that performs entry and exit processing using a medium (e.g., an IC card ticket, a two-dimensional code, a barcode, etc.) held by a passenger. The medium information reading unit 31 then detects the passenger's medium and reads the information stored in the medium. For example, when a passenger holds a two-dimensional code ticket over the medium information reading unit 31, the medium information reading unit 31 detects the frame pattern of the two-dimensional code (detects the medium), and then reads the medium information of the two-dimensional code ticket. The medium information reading unit 31 may also obtain time information indicating the time when the medium information was read from the medium.

[0014] Door 32 is installed at ticket gate 2 and physically blocks the passage of a passenger when the passenger is not permitted to pass through.

[0015] FIG. 2 is a conceptual diagram showing an example of the configuration of the ticket gate 2 when viewed from above. In addition to the medium information reading unit 31 and the door 32, the ticket gate 2 includes a first passage sensor 33, a second passage sensor 34, and a notification unit 35.

[0016] The first passage sensor 33 and the second passage sensor 34 are disposed, for example, on the side of the ticket gate 2. The first passage sensor 33 is capable of detecting whether or not a passenger is present in section A of the passage, and the second passage sensor 34 is capable of detecting whether or not a passenger is present in section B of the passage. Although an example in which there is only one first passage sensor 33 and one second passage sensor 34 is shown in FIG. 2, it goes without saying that each of these may be provided with a plurality of passage sensors.

[0017] The notification unit 35 may be a display or the like arranged on the top of the ticket gate 2. The notification unit 35 may also include a speaker, a lamp, or the like. The notification unit 35 can be used to inform a passenger whether or not he or she is allowed to pass. For example, when a signal permitting the passage of a passenger is received, the notification unit 35 may cause information permitting the passage to be displayed on the display. On the other hand, when a signal not permitting the passage of a passenger is received, the notification unit 35 may announce to the passenger through a speaker that the passenger is not allowed to pass and turn on a lamp in red.

[0018] FIG. 3 is a block diagram showing an example of a hardware configuration of the ticket examiner 2 according to the embodiment. The ticket gate 2 includes a control unit 21, a program storage unit 22, a data storage unit 23, a communication interface 24, and an input / output interface 25. The control unit 21, the program storage unit 22, the data storage unit 23, the communication interface 24, and the input / output interface 25 are connected to each other via a bus so as to be able to communicate with each other.

[0019] The ticket gate 2 can realize various operations using a computer such as a PC (Personal Computer).

[0020] The control unit 21 controls the ticket gate 2. The control unit 21 includes a hardware processor such as a central processing unit (CPU).

[0021] The program storage unit 22 is configured by combining a non-volatile memory such as a solid state drive (SSD) that can be written and read at any time as a storage medium, and a non-volatile memory such as a read only memory (ROM), and stores application programs required for executing various control processes according to an embodiment, in addition to middleware such as an operating system (OS). Hereinafter, the OS and each application program will be collectively referred to as a program.

[0022] The data storage unit 23 may be, for example, a combination of a non-volatile memory such as an SSD, which is writable and readable at any time, and a volatile memory such as a RAM (Random Access Memory), as a storage medium.

[0023] The communication interface 24 includes one or more wired or wireless communication modules. For example, the communication interface 24 includes a communication module that connects to another device via a network by wire or wirelessly. The communication interface 24 may be a general communication interface as long as it can communicate with another device under the control of the control unit 21 and transmit and receive various information.

[0024] The input / output interface 25 is connected to the medium information reading unit 31, the door 32, the first passage sensor 33, the second passage sensor 34, the notification unit 35, and the like. The input / output interface 25 is an interface that enables transmission and reception of information between the medium information reading unit 31, the door 32, the first passage sensor 33, the second passage sensor 34, and the notification unit 35. The input / output interface 25 may include a wired or wireless communication interface. For example, the ticket gate 2 and at least one of the medium information reading unit 31, the door 32, the first passage sensor 33, the second passage sensor 34, and the notification unit 35 are wirelessly connected using a short-range wireless technology or the like, and the transmission and reception of information may be performed using the short-range wireless technology.

[0025] FIG. 4 is a block diagram showing the software configuration of the ticket examiner 2 in the embodiment in relation to the hardware configuration shown in FIG. The data storage unit 23 includes a medium information storage unit 231 and a sensor information storage unit 232 .

[0026] The medium information storage unit 231 is used to store the medium information acquired by the medium information acquisition control unit 211 (described later) at the medium information reading unit 31 .

[0027] The sensor information storage unit 232 is used to store sensor information acquired from the first passage sensor 33 and the second passage sensor 34 by the sensor control unit 214 described later.

[0028] The control unit 21 includes a medium information acquisition control unit 211 , a passability determination unit 212 , a pass control unit 213 , and a sensor control unit 214 .

[0029] The medium information acquisition control unit 211 receives medium detection information indicating that a medium has been detected from the medium information reading unit 31. Furthermore, the medium information acquisition control unit 211 receives medium information from the medium information reading unit 31. The medium information acquisition control unit 211 may receive time information indicating the time when the medium information was read together with the medium information. The medium information acquisition control unit 211 stores the received medium information and time information in the medium information storage unit 231. Furthermore, the medium information acquisition control unit 211 may output the received medium information and time information to the passage permission determination unit 212. Furthermore, the medium information acquisition control unit 211 receives medium information not acquired information indicating that the medium information reading unit 31 was unable to read the medium information. Having received the medium information not acquired information, the medium information acquisition control unit 211 may output a passenger position confirmation signal to the sensor control unit 214 described below.

[0030] The passage permission determination unit 212 determines whether the passenger can pass based on the medium information. For example, the passage permission determination unit 212 may determine whether the passenger can pass based on the medium issuing station, fare, issuing time, time information, etc., included in the medium information. The passage permission determination unit 212 outputs the determination result to the passage control unit 213 and the medium information acquisition control unit 211. Furthermore, upon receiving the medium information non-acquisition information, the passage permission determination unit 212 acquires passenger information about the passenger, and determines whether the medium held up before and the medium whose medium information could not be read are the same based on the passenger information. The passenger information may be, for example, the passenger's position in the passage. Note that a specific determination method will be described later.

[0031] The passage control unit 213 may control opening and closing of the door 32 based on the determination result received from the passage permission determination unit 212. Furthermore, the passage control unit 213 may output information on the permission of passage to the notification unit 35. The notification unit 35 displays the permission of passage on a display or the like based on the information.

[0032] The sensor control unit 214 determines whether the passenger is in section A of the passage, in section B, or has finished passing through the passage, based on the information acquired by the first passage sensor 33 and the second passage sensor 34. Then, the sensor control unit 214 may output the information to the passage permission determination unit 212.

[0033] (operation) FIG. 5 is a flowchart showing an example of a passenger pass authentication procedure at the ticket gate 2 shown in FIG. The operation of this flowchart is realized by the control unit 21 of the ticket gate 2 reading and executing a program stored in the program storage unit 22. For example, during a time period when there are many users, such as rush hour, i.e., during a specified date and time, the control unit 21 may operate in a first mode (rush hour mode). In the operation described below, it is assumed that the control unit 21 operates in the first mode.

[0034] The medium information acquisition control unit 211 receives the first medium detection information (step ST101). When the passenger holds the first medium over the medium information reading unit 31, the medium information reading unit 31 detects the first medium. For example, if the first medium is a two-dimensional code, the medium information reading unit 31 detects the finder pattern of the two-dimensional code and detects that the first medium has been held over the medium information reading unit 31. Then, the medium information reading unit 31 outputs the first medium detection information indicating that the first medium has been detected to the medium information acquisition control unit 211 via the input / output interface 25.

[0035] The medium information acquisition control unit 211 receives the first medium information (step ST102). After detecting the first medium, the medium information reading unit 31 reads the first medium information stored (printed) on the first medium. The medium information reading unit 31 acquires first time information indicating the time when the first medium information was read. Then, the medium information reading unit 31 outputs the first medium information and the first time information to the medium information acquisition control unit 211 through the input / output interface 25. The medium information acquisition control unit 211 stores the received first medium information and first time information in the medium information storage unit 231. Furthermore, the medium information acquisition control unit 211 outputs the first medium information and the first time information to the passability determination unit 212.

[0036] The passage permission determination unit 212 determines whether or not to permit the passenger to pass (step ST103). The passage permission determination unit 212 determines whether or not the passenger can pass based on the first medium information and the first time information received from the medium information acquisition control unit 211. For example, the passage permission determination unit 212 may determine whether or not the passenger can pass based on the medium issuing station, the fare, the issuing time, the time information, and the like included in the first medium information.

[0037] The passage permission determination unit 212 notifies the passage denial (step ST104). When it is determined that the passenger cannot be permitted to pass, the passage permission determination unit 212 notifies the passage denial information to the passage control unit 213. The passage control unit 213, which has received the passage denial information, may output a signal to close the door 32 to the door 32. The door 32 will close the door 32 based on the signal. Furthermore, the passage control unit 213 may output information indicating the reason why the passenger cannot pass to the notification unit 35. The notification unit 35 may display the reason why the passenger cannot pass on a display based on the information, and may provide guidance via a speaker or the like.

[0038] The passage permission determination unit 212 notifies the passage permission (step ST105). When it is determined that the passenger is permitted to pass, the passage permission determination unit 212 notifies the passage permission information to the medium information acquisition control unit 211 and the passage control unit 213. The medium information acquisition control unit 211, which has received the passage permission information, outputs a next passenger signal to the medium information reading unit 31, which enables detection of a medium carried by the next passenger. Upon receiving the next passenger signal, the medium information reading unit 31 enables detection of the next medium. Furthermore, the passage control unit 213, which has received the passage permission information, may output a signal to open the door 32 to the door 32. Furthermore, the passage control unit 213 may output information indicating that the passenger is permitted to pass to the notification unit 35. The notification unit 35 may display information indicating that the passenger is permitted to pass on a display based on the information.

[0039] The medium information acquisition control unit 211 receives the second medium detection information (step ST106). When the passenger holds the second medium over the medium information reading unit 31, the medium information reading unit 31 detects the second medium. For example, the second medium may be the same as the first medium. Alternatively, the passenger may continue to hold the first medium over the medium information reading unit 31, and as a result, the first medium may be detected as the second medium. Of course, the next passenger may hold a second medium different from the first medium over the medium information reading unit 31. Then, the medium information reading unit 31 outputs the second medium detection information indicating that the second medium has been detected to the medium information acquisition control unit 211 via the input / output interface 25.

[0040] The medium information acquisition control unit 211 receives the second medium information non-acquisition information (step ST107). If the passenger removes the second medium from the medium information reading unit 31 before the medium information reading unit 31 reads the second medium information from the second medium, the medium information reading unit 31 cannot read the second medium information. Therefore, the medium information reading unit 31 outputs, via the input / output interface 25, to the medium information acquisition control unit 211, the second medium information non-acquisition information indicating that the second medium information could not be read and second time information indicating the time when the second medium information could not be acquired.

[0041] Having received the second medium information non-acquisition information, medium information acquisition control unit 211 acquires the first medium information, which is the most recently acquired medium information, and the first time information, from medium information storage unit 231. Then, medium information acquisition control unit 211 outputs to sensor control unit 214 a passenger position confirmation signal for confirming the position of the passenger during the time period from the first time indicated by the first time information to the second time indicated by the second time information.

[0042] The sensor control unit 214 determines the position of the passenger (step ST108). Having received the passenger position confirmation signal, the sensor control unit 214 determines where the passenger is located in the passage of the ticket gate 2 from the first time to the second time. 1 That is, the sensor control unit 214 determines whether the first passenger is present based on the second medium information non-acquisition information. 1 For example, the sensor control unit 214 determines the position of the passenger based on information acquired from each of the first passage sensor 33 and the second passage sensor 34. Then, the sensor control unit 214 outputs passenger position information indicating the determined position of the passenger to the passage permission determination unit 212.

[0043] The passage permission / prohibition determination unit 212 determines whether the first medium and the second medium are the same (step ST109). 1Based on passenger position information, which is passenger information about the passenger, the passage permission / prohibition determination unit 212 determines whether the second medium is the same as the first medium. For example, if the passenger position information indicates that the passenger remains in a predetermined area, section A, from the first time to the second time, the passage permission / prohibition determination unit 212 determines that the second medium is the same as the first medium. That is, the passage permission / prohibition determination unit 212 determines that the first passenger who holds the first medium and the second passenger who holds the second medium are the same. In this case, the process proceeds to step ST110. On the other hand, if the passenger position information indicates other than the above conditions, for example, that the first passenger is in section B or has passed section B, the passage permission / prohibition determination unit 212 determines that the passenger who holds the first medium over the medium information reading unit 31 and the passenger who holds the second medium over the medium information reading unit 31 are different. In this case, the process proceeds to step ST111.

[0044] The passage permission / prohibition determination unit 212 notifies the same medium information (step ST110). When it is determined that the first medium and the second medium are the same, the passage permission / prohibition determination unit 212 notifies the same medium information to the medium information acquisition control unit 211 and the passage control unit 213. The medium information acquisition control unit 211 that has received the same medium information outputs a next passenger signal that enables detection of a medium held by the next passenger to the medium information reading unit 31. When the medium information reading unit 31 receives the next passenger signal, it enables detection of the next medium. In addition, the sensor control unit 214 may determine the position of the first passenger and output a passing signal indicating that the first passenger has passed through the section B to the passage permission / prohibition determination unit 212. Then, the passage permission / prohibition determination unit 212 may output an instruction to the passage control unit 213 to keep the door 32 open until the passing signal is received. The passage control unit 213 opens the door 32 in response to the instruction and waits for the first passenger to pass through.

[0045] The passage permission determination unit 212 notifies the passage prohibition (step ST111). When it is determined that the first medium and the second medium are not the same, that is, the first passenger and the second passenger are not the same, the passage permission determination unit 212 notifies the passage control unit 213 of passage prohibition information indicating that the second passenger is not permitted to pass.

[0046] The passage permission determination unit 212, which has received the no-passage information, receives information on the position of the first passenger from the sensor control unit 214. Then, when the position of the first passenger indicates that the first passenger has not passed through section B, the passage permission determination unit 212 may output an instruction to the passage control unit 213 to keep the door 32 open but not to allow the second passenger to pass. The passage control unit 213 may control the door 32 to keep open, while outputting information that the second passenger cannot pass to the notification unit 35. The notification unit 35 may display the reason for the no-passage to the passenger on a display based on the information, and may provide guidance via a speaker or the like.

[0047] On the other hand, when the position of the first passenger indicates that the passenger is passing through section B, a signal to close the door 32 may be output to the door 32. The passage permission determination unit 212 may output an instruction to the passage control unit 213 to close the door 32 and not allow the second passenger to pass. The passage control unit 213 may control the door 32 to close, and output information that the second passenger cannot pass to the notification unit 35. The notification unit 35 may display the reason why the passenger cannot pass on a display based on the information, and may provide guidance via a speaker or the like.

[0048] (Effects of the first embodiment) According to the embodiment described above, even if the first passenger who has been permitted to pass holds the medium over the medium information reading unit 31 again and then removes it, or continues to hold the medium over the medium but then removes it, and the medium information of the medium held over again cannot be read, the control unit 21 of the ticket gate 2 can determine that the medium held over again is the same medium (the same passenger) based on the passenger information about the passenger (passenger position). In other words, the ticket gate 2 can prevent the same medium from being read twice. This allows the ticket gate 2 to permit passage without the passenger having to hold the medium over the medium again.

[0049] [Second embodiment] (composition) The configuration according to the second embodiment is the same as that of the first embodiment described with reference to FIGS. 1 to 4, and therefore a description thereof will be omitted here.

[0050] (operation) FIG. 6 is a flowchart showing an example of a passenger pass authentication procedure at the ticket gate 2 shown in FIG. The operation of this flowchart is realized by the control unit 21 of the ticket gate 2 reading and executing a program stored in the program storage unit 22. For example, during a time period when the number of users is small compared to rush hour, such as during normal times, that is, during a time period other than the specific date and time described in the first embodiment, the control unit 21 may operate in the second mode (normal mode). In the operation described below, the control unit 21 is assumed to operate in the second mode. That is, the control unit 21 may be capable of switching between the first mode and the second mode depending on the date and time (rush hour and non-rush hour).

[0051] Here, steps ST201 to ST206 are the same as steps ST101 to ST106 described with reference to FIG. 4, and therefore the description of these steps will be omitted.

[0052] The medium information acquisition control unit 211 receives the second medium information non-acquisition information (step ST207). If the passenger removes the second medium from the medium information reading unit 31 before the medium information reading unit 31 reads the second medium information from the second medium, the medium information reading unit 31 cannot read the second medium information. Therefore, the medium information reading unit 31 outputs, via the input / output interface 25, to the medium information acquisition control unit 211, the second medium information non-acquisition information indicating that the second medium information could not be read and second time information indicating the time when the second medium information could not be acquired. Then, the medium information acquisition control unit 211 outputs the received second medium information non-acquisition information to the passage permission determination unit 212.

[0053] The passage permission determination unit 212 notifies the passenger that passage is not permitted (step ST208). Having received the medium information non-acquisition information, the passage permission determination unit 212 notifies the passage control unit 213 of the passage prohibition information. The passage control unit 213, having received the passage prohibition information, may output a signal to close the door 32 to the door 32. The door 32 will close the door 32 based on the signal. Furthermore, the passage control unit 213 may output information indicating the reason why the passenger is not permitted to pass to the notification unit 35. The notification unit 35 may display the reason why passage is not permitted to the passenger on a display based on the information, and may provide guidance via a speaker or the like.

[0054] When control unit 21 operates in the second mode as in the second embodiment, if control unit 21 detects a passenger's medium but cannot read the medium information, control unit 21 of ticket gate 2 does not allow the passenger to pass. In this case, the second passenger holds the medium over medium information reading unit 31 again.

[0055] The medium information reading unit 31 receives the second medium information detection information (step ST209). When the passenger holds the second medium over the medium information reading unit 31, the medium information reading unit 31 detects the second medium. For example, the second medium may be the same as or different from the first medium. Then, the medium information reading unit 31 outputs the second medium detection information indicating that the second medium has been detected to the medium information acquisition control unit 211 via the input / output interface 25.

[0056] The medium information acquisition control unit 211 receives the second medium information (step ST210). After detecting the second medium, the medium information reading unit 31 reads the second medium information stored (printed) on the second medium. The medium information reading unit 31 acquires third time information indicating the time when the second medium information was read. Then, the medium information reading unit 31 outputs the second medium information and the second time information to the medium information acquisition control unit 211 through the input / output interface 25. The medium information acquisition control unit 211 acquires the first medium information and the first time information received immediately before the second medium information from the medium information storage unit 231. Then, the medium information acquisition control unit 211 outputs the first medium information, the first time information, the second medium information, and the third time information to the passability determination unit 212.

[0057] The passage permission / prohibition determination unit 212 determines whether or not to permit the passenger to pass (step ST211). The passage permission / prohibition determination unit 212 determines whether or not to permit the passenger to pass based on the first medium information, the first time information, the second medium information, and the second time information received from the medium information acquisition control unit 211. For example, when the first medium information and the second medium information are the same and the time difference between the first time information and the third time information is within a predetermined time, the passage permission / prohibition determination unit 212 determines that the passenger has held up the first medium again and permits the passenger to pass. When the first medium information and the second medium information are different, the passage permission / prohibition determination unit 212 may determine whether or not to permit the passenger to pass based on the second medium information, assuming that a passenger different from the first passenger has held up the second medium over the medium information reading unit 31.

[0058] The passage permission determination unit 212 notifies the passage denial (step ST212). When it is determined that the passenger cannot be permitted to pass, the passage permission determination unit 212 notifies the passage denial information to the passage control unit 213. The passage control unit 213, which has received the passage denial information, may output a signal to close the door 32 to the door 32. The door 32 will close the door 32 based on the signal. Furthermore, the passage control unit 213 may output information indicating the reason why the passenger cannot pass to the notification unit 35. The notification unit 35 may display the reason why the passenger cannot pass on a display based on the information, and may provide guidance via a speaker or the like.

[0059] The passage permission determination unit 212 notifies the passage permission (step ST213). When it is determined that the passenger is permitted to pass, the passage permission determination unit 212 notifies the medium information acquisition control unit 211 and the passage control unit 213 of the passage permission information. For example, when the first medium and the second medium are the same and the difference between the first time and the second time is a predetermined time, the passage permission determination unit 212 notifies the medium information acquisition control unit 211 and the passage control unit 213 of the passage permission. The medium information acquisition control unit 211 that has received the passage permission information outputs a next passenger signal that enables detection of a medium held by the next passenger to the medium information reading unit 31. When the medium information reading unit 31 receives the next passenger signal, it enables detection of the next medium. Furthermore, the passage control unit 213 that has received the passage permission information may output a signal to open the door 32 to the door 32.

[0060] (Effects of the second embodiment) According to the embodiment described above, if the first passenger who has been permitted to pass holds the medium over medium information reading unit 31 again and then removes it, or continues to hold the medium over the medium but then removes it, and the medium information of the medium that has been held over again cannot be read, the passenger is requested to hold the medium over again. By reading the medium information again in this manner, it is possible to more reliably determine that the first passenger and the passenger who held the medium over again are the same person.

[0061] [Third embodiment] (composition) FIG. 7 is a block diagram showing the hardware and software configurations of the ticket examiner 2 in the embodiment. The hardware configuration of the ticket gate 2 of the third embodiment differs from that of the first embodiment in that it includes a camera 36. Also, the software configuration of the third embodiment differs from that of the first embodiment in that the control unit 21 includes a face data acquisition unit 215, and the data storage unit 23 includes a face data storage unit 233.

[0062] Camera 36 is installed so as to ensure a shooting range that allows the face of a passenger passing through the passage to be photographed. Therefore, camera 36 may be installed on ticket gate 2, or may be installed at a location separate from ticket gate 2. Here, in the example shown in FIG. 7, camera 36 is disposed on ticket gate 2. Camera 36 starts shooting when ticket gate 2 is started, that is, when control unit 21 is in a state where it is possible to determine whether or not to allow a passenger to pass. Camera 36 outputs the image to face data acquisition unit 215, which will be described later, via input / output interface 25.

[0063] The face data acquisition unit 215 acquires face data based on the captured image received from the camera 36. The face data acquisition unit 215 may store the acquired face data in the face data storage unit 233 described later. The face data acquisition unit 215 may also output the acquired face data to the passability determination unit 212.

[0064] The passability determination unit 212 may perform face authentication based on the received face data and the data stored in the face data storage unit 233. For example, the passability determination unit 212 determines whether the face data received from the face data acquisition unit 215 is stored in the face data storage unit 233.

[0065] The face data storage unit 233 stores face data of passengers who use the ticket gate 2. For example, face data received from the face data acquisition unit 215 may be stored. Furthermore, the face data storage unit 233 may store face data registered in advance. For example, the control unit 21 acquires face data from a face image captured by a camera installed in the ticket machine, and stores the face data in the face data storage unit 233. Alternatively, the control unit 21 may receive a face image of the user's own face captured by a mobile terminal or the like carried by the passenger through the communication interface 24, acquire face data based on the acquired face image, and store the face data in the face data storage unit 233.

[0066] (operation) FIG. 8 is a flowchart showing an example of a passenger passage authentication procedure at the ticket gate 2 shown in FIG. The operation of this flowchart is realized by the control unit 21 of the ticket gate 2 reading and executing a program stored in the program storage unit 22. Note that the control unit 21 may be in either the first mode or the second mode.

[0067] Step ST301 is the same as step ST101 described with reference to FIG. 5, and therefore a description thereof will be omitted here.

[0068] The medium information acquisition control section 211 receives the first medium information (step ST302). The operations performed by the medium information acquisition control section 211 and the medium information reading section 31 are the same as those in step ST102 described with reference to Fig. 5 except for the matters described below, and therefore will not be described here. The medium information acquisition control section 211 may output a signal indicating that the medium information has been received to the face data acquisition section 215.

[0069] The face data acquisition unit 215, which has received the signal indicating that the medium information has been received, may detect the first passenger based on the captured image from the camera 36, ​​and acquire face data of the first passenger. Then, the face data acquisition unit 215 may store the acquired first face data in the face data storage unit 233. Note that the face data acquisition unit 215 may store the first face data and the first medium information in the face data storage unit 233 in association with each other.

[0070] Steps ST303 to ST306 are the same as steps ST103 to ST106 described with reference to FIG. 5, and therefore a description thereof will be omitted here.

[0071] The medium information acquisition control unit 211 receives the second medium information non-acquisition information (step ST307). If the passenger removes the second medium from the medium information reading unit 31 before the medium information reading unit 31 reads the second medium information from the second medium, the medium information reading unit 31 cannot read the second medium information. Therefore, the medium information reading unit 31 outputs, via the input / output interface 25, to the medium information acquisition control unit 211, the second medium information non-acquisition information indicating that the second medium information could not be read and second time information indicating the time when the second medium information could not be acquired.

[0072] Having received the second medium information non-acquisition information, medium information acquisition control unit 211 acquires the first medium information and the first time information, which are the most recently acquired medium information, from medium information storage unit 231. Then, medium information acquisition control unit 211 outputs the first medium information, the first time information, and the second time information to passage permission determination unit 212. Furthermore, medium information acquisition control unit 211 outputs an instruction to face data acquisition unit 215 to acquire face data of the second passenger.

[0073] The face data acquisition unit 215 acquires face data of the second passenger (step ST308). The face data acquisition unit 215, which has received an instruction from the medium information acquisition control unit 211, detects the second passenger based on the image captured by the camera 36, ​​and acquires face data of the second passenger. Then, the face data acquisition unit 215 outputs the second face data to the passage permission determination unit 212.

[0074] The passage permission / prohibition determination unit 212 determines whether the facial data of the second passenger can be authenticated (step ST309). The passage permission / prohibition determination unit 212 determines whether the second facial data corresponds to the first facial data. That is, the passage permission / prohibition determination unit 212 executes facial authentication of the second facial data. For example, the passage permission / prohibition determination unit 212 determines whether data corresponding to the second facial data is stored in the facial data storage unit 233. When it is determined that the facial data corresponding to the second facial data is stored in the facial data storage unit 233, that is, that the second facial data can be authenticated, the passage permission / prohibition determination unit 212 determines that the first medium and the second medium are the same. Then, the process proceeds to step ST310. On the other hand, when the facial data of the second passenger cannot be authenticated, the passage permission / prohibition determination unit 212 determines that the first medium and the second medium are not the same. Then, the process proceeds to step ST311.

[0075] The passage permission determination unit 212 notifies the same medium information (step ST110). When it is determined that the second face data can be authenticated, that is, that the first medium and the second medium are the same, the passage permission determination unit 212 notifies the same medium information to the medium information acquisition control unit 211 and the passage control unit 213. The medium information acquisition control unit 211, which has received the same medium information, outputs a next passenger signal to the medium information reading unit 31, which enables detection of the medium held by the next passenger. Upon receiving the next passenger signal, the medium information reading unit 31 enables detection of the next medium. Furthermore, the passage control unit 213, which has received the same medium information, may output a signal to the door 32 to keep the door 32 open.

[0076] The passage permission / prohibition determination unit 212 notifies the passage prohibition (step ST111). When it is determined that the second data cannot be authenticated, that is, that the first medium and the second medium are not the same, the passage permission / prohibition determination unit 212 notifies the passage prohibition information to the passage control unit 213. The passage control unit 213 that receives the passage prohibition information may output a signal to the door 32 to close the door 32. The door 32 will close the door 32 based on the signal. Furthermore, the passage control unit 213 may output information indicating the reason why the passenger cannot pass to the notification unit 35. The notification unit 35 may display the reason why the passenger cannot pass on a display based on the information, and may provide guidance via a speaker or the like.

[0077] (Effects of the third embodiment) According to the embodiment described above, even if the first passenger who has been permitted to pass holds the medium over the medium information reading unit 31 again and then removes it, or continues to hold the medium over the medium but then removes it, and the medium information of the medium held over again cannot be read, the control unit 21 of the ticket gate 2 can determine that the medium held over again is the same medium based on the passenger information (face authentication) about the passenger. In other words, the ticket gate 2 can prevent the same medium from being read twice. This allows the ticket gate 2 to permit passage without the passenger having to hold the medium over the medium again.

[0078] [Other embodiments] The present invention is not limited to the above embodiment. For example, the first embodiment and the third embodiment may be combined. The control unit 21 may determine whether the passengers are the same based on the passenger's position in the passage and the passenger's face data.

[0079] In short, this invention is not limited to the above-mentioned embodiment, and various modifications can be made in the implementation stage without departing from the gist of the invention. Moreover, each embodiment may be implemented in combination as appropriate as possible, and in that case, the combined effect can be obtained. Furthermore, the above-mentioned embodiment includes inventions at various stages, and various inventions can be extracted by appropriate combinations of the disclosed constituent elements.
