[Medium]
FIG. 1 is a diagram showing a comparison between the first medium M1 and the second medium M2. The first medium M1 is a ticket on which code information is printed (for example, a code image ticket). The code information is information in which some information is encoded and displayed as a bar code or a two-dimensional code (for example, a QR code (registered trademark)). Coding means converting information into a state in which a person cannot directly recognize the content of the information. The code information is printed on the first medium M1 in a state where a person can visually recognize the position. In the following description, it is assumed that the QR code CD is used as the code information.

On the first medium M1 shown in FIG. 1, for example, a QR code CD is printed on the base material 10. The QR code CD is an example of a "code image". The QR code CD shows, for example, finder patterns FP1 to FP3 for detecting the position and direction of the code. Further, the QR code CD is encoded (encoded) with the first validity information as a ticket for the first medium M1. The first validity information is information indicating the validity of the ticket, for example, it is possible to board in the section from A station to B station, or to board from A station to XX yen, or to board in the XX section. Includes information such as available section information and boardable dates. The first efficacy information may be only the first medium ID that identifies the first medium M1. The QR code CD is generated by the ticket issuing machine when the first medium M1 is issued, and is printed on the base material 10. The QR code CD, barcode, or the like may not be printed directly on the base material 10, but may be attached to the first medium M1 by affixing a sticker or the like on which they are printed to the base material 10. ..

The second medium M2 is a medium having a communication function (for example, an IC (Integrated Circuit) card). The second medium M2 includes, for example, a base material 20, a chip 30, and an antenna 40. The chip 30 is, for example, a passive type IC chip embedded inside the base material 20 without being exposed to the outside. The chip 30 is an example of a “second medium communication unit”. The chip 30 uses RFID (Radio Frequency IDentifier) technology to transmit and receive information to and from the automatic ticket gate 100, which will be described later. The chip 30 communicates with the automatic ticket gate 100, for example, by using radio waves in the HF band (short wave band; 13.56 MHz band). The chip 30 responds to a command transmitted by the automatic ticket gate 100 and executes processing based on a command response method for transmitting information.

The chip 30 includes, for example, a transmission / reception unit 32, a control circuit 34, and a storage unit 36. The transmission / reception unit 32 extracts driving power from the radio waves transmitted by the automatic ticket gate 100 and demodulates the information contained in the radio waves. The transmission / reception unit 32 outputs the demodulated information to the control circuit 34. Further, the transmission / reception unit 32 generates a radio wave for superimposing information, and superimposes the information on the generated radio wave.

The control circuit 34 writes information to the storage unit 36 and reads out the information written to the storage unit 36 according to the content of the command transmitted by the automatic ticket gate 100. Further, the control circuit 34 reads the information stored in the storage unit 36 using the transmission / reception unit 32 and the antenna 40, and transmits the read information to the automatic ticket gate 100.

The storage unit 36 stores, for example, identification information of the second medium M2 and second validity information as a ticket for the second medium M2. The second validity information is, for example, the balance of electronic money, the valid section as a commuter pass, the expiration date, and the like. Further, in addition to the second effect information, the storage unit 36 may store information on the entrance station, the date and time of entry, and the like. The antenna 40 is, for example, a coiled loop antenna.

[Automatic ticket gate]
FIG. 2 is a diagram showing an external configuration of the automatic ticket gate 100. The automatic ticket gate 100 includes, for example, a display unit 110, a door unit 120, and a reader / writer 130. The automatic ticket gate 100 controls the passage of the user in the A direction in the figure. The display unit 110 displays various information. The door portion 120 is controlled to be in an open state or a closed state depending on the result of processing performed on the first medium M1 or the second medium M2.

The reader / writer 130 is provided with a target area Atgt. The target area Atgt is provided so as to be included in an acquireable area in which the information encoded in the QR code CD is acquired and a communicable area in which the reader / writer 130 and the second medium M2 can communicate with each other. Can be visually recognized and the position can be known. In the target area Atgt, for example, information urging the medium to be held is displayed, or a color or pattern is added so as to be distinguished from other areas. Further, the target area Atgt may be formed at a height different from that of the other areas (so as to protrude as compared with the other areas), and the target area Atgt is provided with an illumination unit, and the illumination unit is provided. It may be lit or blinking. In this way, since the target area Atgt is provided so as to be distinguishable from other areas, the user can visually recognize the area holding the medium. Details of the acquireable area and the communicable area will be described later.

When the user brings the surface on which the QR code CD of the first medium M1 is displayed closer to the reader / writer 130, the reader / writer 130 displays the first efficacy information encoded by the QR code CD of the first medium M1. get. Further, when the user brings the second medium M2 close to the target area Atgt, the reader / writer 130 and the second medium M2 communicate with each other, and the communication unit 134 acquires the second efficacy information stored in the storage unit 36. .. Based on the validity information of one of the acquired first validity information and the second validity information, it is determined whether or not the user can pass through the automatic ticket gate 100.

FIG. 3 is an internal configuration diagram of the reader / writer 130 as seen from the arrow Y direction of FIG. The reader / writer 130 includes, for example, an antenna 132, a communication unit 134, a camera (an example of an image pickup unit) 140, and a light 142.

The antenna 132 is, for example, a patch antenna. The antenna 132 performs non-contact power supply by transmitting a radio wave having a frequency band of the HF band to the chip 30 of the second medium M2, and wirelessly communicates with the chip 30 of the second medium M2 using the radio wave. conduct.

The communication unit 134 includes a controller, a modulation unit, a demodulation unit, and the like. The controller controls the modulation unit and the demodulation unit. The modulation unit superimposes a command on a radio wave having a frequency band of the HF band, and transmits the radio wave to the antenna 132. Further, the demodulation unit demodulates the information contained in the radio wave acquired via the antenna 132, and outputs the demodulated information (command) to the control device 150 described later.

The camera (imaging unit) 140 captures a QR code CD of the first medium M1 held in the target region Atgt by the user. The light 142 irradiates the first medium M1 with light when the image pickup operation is performed by the camera 140. For example, the reader / writer 130 has a sensor that outputs an on signal when the first medium M1 or the like is brought close to the target area Atgt by the user. The camera 140 captures a QR code CD when it acquires an on signal output by the sensor. When the light 142 acquires the on signal output by the sensor, the light 142 irradiates the light together with the image pickup operation of the camera 140. The antenna 132 is provided at a position that does not block the image pickup region of the camera 140 and the region where the light 142 irradiates the light. For example, the antenna 132 is wound around the optical axis of the camera 140 and the light 142. As a result, the camera 140 can image the QR code CD without blocking the image pickup area by the antenna 132 and the antenna 132.

FIG. 4 is a functional configuration diagram of the control device 150. The control device 150 includes, for example, a recognition unit 152, a control unit 154, a determination unit 156, a passage control unit 158, and a ticket gate side storage unit 160. The recognition unit 152, the control unit 154, the determination unit 156, and the passage control unit 158 are realized by, for example, a hardware processor such as a CPU (Central Processing Unit) executing a program (software). In addition, some or all of these functional parts are hardware (circuits) such as LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), GPU (Graphics Processing Unit), etc. It may be realized by the part; including circuitry), or it may be realized by the cooperation of software and hardware.

The ticket gate side storage unit 160 is, for example, a non-volatile storage medium such as a ROM (Read Only Memory), a flash memory, an HDD (Hard Disk Drive), an SD card, and a volatile nature such as a RAM (Random Access Memory) and a register. It is realized by the storage medium of. The ticket gate side storage unit 160 stores a program executed by the processor, a charge table 162 in which charges between stations (or for each usage distance) are stored, identification information of the station where the own machine is installed, and own. Stores the identification information of the aircraft, the distance between each station, etc.

The recognition unit 152 performs decoding processing on the data of the image captured by the camera 140 and converts it into information (electronic information) that can be recognized by a computer and is represented by a bit string or the like. For example, the recognition unit 152 reads the information encoded in the QR code CD displayed on the first medium M1. The combination of the recognition unit 152, the camera 140, and the light 142 is an example of an "optical reader". Hereinafter, the recognition unit 152, the camera 140, and the light 142 may be collectively referred to as an optical reading unit.

The control unit 154 operates the communication unit 134 and the optical reading unit in the standby state. The standby state is, for example, a state in which neither the first medium M1 nor the second medium M2 is detected, and the first medium M1 or the second medium M2 is waiting for a new approach. Further, the control unit 154 passes the user to the determination unit 156 based on the first effect information read by the optical reading unit or the second effect information stored in the second medium obtained by the communication unit 134. Have them decide whether or not to accept it. The details of the function of the control unit 154 will be described later.

The determination unit 156 determines whether or not the user can pass through the automatic ticket gate 100 based on the information acquired by the optical reading unit or the communication unit 134. For example, when the determination unit 156 acquires the available section information from the first effect information, the determination unit 156 determines whether or not the section from the entrance station to the exit station is included in the available section. Judgment unit 156 permits the passage of the user when the section from the entrance station to the exit station is included in the available section, and the user when the section from the entry station to the exit station is not included in the available section. Prohibit the passage of. In addition, when the available section is an available section from A station to XX yen, the determination unit 156 refers to the fare table 162 and the section from the boarding station to the getting-off station is XX yen. Whether or not the user can pass through may be determined depending on whether or not the user is within the range.

Further, the determination unit 156 determines whether or not the minimum charge for admission is charged based on the second efficacy information at the time of entry, and determines whether or not the fare from the entrance station is charged at the time of entry. judge. At the time of admission, the determination unit 156 determines that the user can pass through the automatic ticket gate 100 if the minimum charge is charged, and if the minimum charge is not charged, the user is the automatic ticket gate 100. Is determined to be unable to pass. Further, the determination unit 156 determines that the user can pass through the automatic ticket gate 100 when the fare from the entrance station is charged at the time of entry, and when the fare from the entrance station is not charged. Determines that the user cannot pass through the automatic ticket gate 100.

The passage control unit 158 executes control for permitting or prohibiting the passage of the user based on the determination result of the determination unit 156. When controlling to prohibit the passage of the user, the passage control unit 158 closes the door unit 120 or causes the display unit 110 to display information indicating the prohibition of passage. When controlling the passage of the user, the passage control unit 158 opens the door unit 120 or causes the display unit 110 to display information indicating the passage permission.

[Control function]
Next, the details of the function of the control unit 154 will be described. The control unit 154 operates the communication unit 134 and the optical reading unit in the standby state. Then, when the communication unit 134 communicates with the second medium communication unit while the predetermined image is recognized by the recognition unit 152 among the images read by the optical reading unit, the control unit 154 causes the second medium M2. Do not allow passage based on the second efficacy information stored in. The predetermined image is, for example, the finder patterns FP1 to FP3 included in the QR code CD.

Here, a specific example of the control content of the control unit 154 described above will be described. For example, the recognition unit 152 recognizes at least one of the finder patterns FP1 to FP3 of the QR code CD, and recognizes the position and orientation of the QR code. Since the shapes of the finder patterns FP1 to FP3 are easier to authenticate than the position of each cell (dot) in the QR code, they can be recognized even from a position away from the touch surface of the reader / writer 130.

FIG. 5 is a diagram illustrating an acquireable area of the finder pattern FP of the first medium M1 and a communicable area with the second medium M2. In the example of FIG. 5, the first region AR1 is an acquireable region in which the optical reading unit can acquire the fine patterns FP1 to FP3 from the QR code CD of the first medium M1. The second area AR2 is a communicable area in which the communication unit 134 can communicate with the second medium M2. The first region AR1 has a wider acquireable region than the second region AR2. Therefore, for example, when the first medium M1 and the second medium M2 are overlapped and brought close to the touch surface TS, the finder pattern is performed by the first medium M1 before the communication between the second medium M2 and the communication unit 134 is performed. FP1 to FP3 can be recognized.

Further, the recognition unit 152 has the first effect from the QR code CD of the first medium M1 that is closer to the touch surface TS based on the position and orientation of the QR code CD recognized by the recognized finder patterns FP1 to FP3. Get all the information. FIG. 6 is a diagram illustrating an area in which the first efficacy information of the first medium M1 can be obtained. In the example of FIG. 6, the third region AR3 is an acquireable region in which the optical reading unit can acquire all of the first efficacy information from the QR code CD of the first medium M1. The third region AR3 has a narrower acquireable region than the second region AR2. Therefore, for example, when the first medium M1 and the second medium M2 are overlapped and brought close to the touch surface TS, the second medium M2 is used before the first medium M1 acquires all of the first efficacy information. Communication between the chip 30 and the communication unit 134 is started, and the passability determination is executed based on the second efficacy information acquired from the second medium M2.

Therefore, when the control unit 154 communicates with the chip 30 of the second medium M2 while the finder patterns FP1 to FP3 are recognized by the first medium M1, the control unit 154 stores the finder patterns FP1 to the second medium M2. 2 Do not allow passage based on efficacy information. In this case, the control unit 154 causes, for example, the passage control unit 158 to close the door unit 120. Further, the control unit 154 causes the display unit 110 to display information prompting the user to hold either the first medium M1 or the second medium M2 in the target area by the passage control unit 158.

FIG. 7 is a diagram showing an example of an image IM displayed on the display unit 110. The passage control unit 158 has information indicating that the first medium M1 and the second medium M2 are overlapped on the display unit 110 and held over the reader / writer 130 (for example, "IC card ticket and QR ticket". Both were detected. Please hold either one. ") Is displayed. As a result, only the medium containing the effect information intended by the user is held, so that it is possible to execute a process such as passability determination using the effect information intended by the user.

When the user possesses both the first medium M1 and the second medium M2, it is presumed that there is a high possibility that the passability determination using the first medium M1 will be performed. Therefore, when the control unit 154 communicates with the chip 30 of the second medium M2 while the finder patterns FP1 to FP3 are recognized by the first medium M1, the control unit 154 obtains the first medium M1. The passability determination may be executed with priority given to the validity information. As a result, the user M can save the trouble of holding the first medium M1 again, and can quickly determine whether or not to pass through.

When the communication unit 134 communicates with the chip 30 of the second medium M2 while the image FPa is recognized by the recognition unit 152, the control unit 154 has a second effect stored in the storage unit 36 of the second medium M2. Do not allow informed passage.

FIG. 8 is a flowchart showing a flow of processing executed by the automatic ticket gate 100 of the present embodiment. The example of FIG. 8 shows the flow of processing in a state in which the communication unit 134 is operated and the optical reading unit is operated in the standby state.

First, the control unit 154 determines whether or not the finder pattern FP of the QR code CD displayed on the first medium M1 is recognized (step S100). When the finder pattern FP is recognized, the control unit 154 next determines whether or not communication with the second medium communication unit (chip 30) has been established (step S102). When communication with the second medium communication unit is established, the control unit 154 does not allow passage based on the second efficacy information stored in the second medium (step S104).

Next, the control unit 154 displays the information prompting the user to hold either the first medium or the second medium (step S106), and returns to the process of step S100. Further, in the process of step S102, when communication with the second medium communication unit is not established, the control unit 154 determines whether or not all of the QR code CDs displayed on the first medium M1 have been recognized (). Step S108). When all of the QR code CDs are recognized, the determination unit 156 determines whether or not the user can pass through based on the first efficacy information recognized from the QR code CD (step S110). Next, the passage control unit 158 controls the opening and closing of the door unit based on the determination result (step S112).

Further, in the process of step S100, when the finder pattern displayed on the first medium M1 is not recognized, the control unit 154 determines whether or not the communication with the second medium communication unit is established (step S114). ). When communication with the second medium communication unit is established, the control unit 154 reads out the second efficacy information stored in the second medium M2 (step S116). The second effect information to be read is, for example, the balance of electronic money. Next, the determination unit 156 determines whether or not to pass the passage based on the read second efficacy information (step S118).

Next, the control unit 154 determines whether or not the user can pass through the automatic ticket gate 100 as a determination result by the determination unit 156 (step S120). When it is determined that the passage is possible, the control unit 154 determines whether or not the finder pattern FP displayed on the first medium M1 is recognized (step S122). When the finder pattern FP is recognized, the control unit 154 displays on the display unit 110 information prompting the user to hold either the first medium M1 or the second medium M2 (step S124). Further, the passage control unit 158 closes the door unit 120 to prevent the user from passing through (step S125). Further, in the process of step S122, when the finder pattern FP displayed on the first medium M1 is not recognized, the control unit 154 determines whether or not the communication with the second medium communication unit is established (step). S126). When communication with the second medium communication unit is established, predetermined information is written in the storage unit of the second medium M2 (step S128). The predetermined information is, for example, the entrance station and the date and time of entry when the entrance process is performed, and the new charge balance after deducting the fare when the entry process is performed. Next, the passage control unit 158 opens the door unit 120 to allow the user to pass through (step S130).

Further, in the process of step S126, when communication with the second medium communication unit is not established, the passage control unit 158 closes the door unit 120 to prevent the user from passing (step S132). Further, when all the QR code CDs displayed on the first medium M1 cannot be recognized in the process of step S108, when the communication with the second medium communication unit is not established in the process of step S114, or in step. When it is determined in the process of S120 that the user cannot pass through, the passage control unit 158 closes the door unit 120 to prevent the user from passing through (step S132). As a result, the processing of this flowchart ends.

[Variation example of the first medium M1]
For example, if the finder pattern FP cannot be read from the QR code CD displayed on the first medium M1, or before the finder pattern FP can be read, the second medium communication unit and the communication unit 134 communicate with each other. there is a possibility. In this case, the user may make a passability determination based on the second efficacy information obtained by the second medium M2, contrary to the intention of passing through the automatic ticket gate 100 using the first medium M1.

Therefore, as a modification of the first medium M1, an image imitating a finder pattern may be displayed on the first medium M1. FIG. 9 is a diagram showing an example of a first medium M1a in which an image imitating a finder pattern is displayed. Compared to the first medium M1 shown in FIG. 1, the first medium M1a shown in FIG. 9 has an image FPa imitating one of the finder patterns FP1 to FP3 near the QR code CD printed on the base material 10A. It is displayed. The vicinity of the QR code CD is a range within a predetermined distance (for example, about 1 [cm]) from the QR code CD.

The image FPa is printed larger than, for example, the finder patterns FP1 to FP3. For example, when the first medium M1a and the second medium M2 are overlapped with each other and brought close to the touch surface TS, the image FPa is generated by the recognition unit 152 before the second medium communication unit communicates with the communication unit 134. The image FPa is printed in a recognized size. The image FPa is, for example, a finder pattern FP magnified by a predetermined magnification.
As a result, the control unit 154 recognizes the image FPa before the communication between the second medium communication unit and the communication unit 134 is performed, and does not allow the passage based on the second efficacy information stored in the second medium. Can be controlled as such.

According to at least one embodiment described above, the optical reading unit (140, 142, 152) that optically reads the first efficacy information from the code image displayed on the first medium M1 and the second efficacy information are The communication unit (134) that communicates with the chip 30 of the stored second medium M2, the first efficacy information read by the optical reading unit (140, 142, 152), or the second effect information obtained by the communication unit 134. It is a control unit 154 that determines whether or not the user can pass through based on the second efficacy information stored in the medium, and is a communication unit 134 in a state where a predetermined image is recognized by the optical reading unit (140, 142, 152). By having a control unit 154 that does not allow passage based on the second efficacy information stored in the second medium M2 obtained by the communication unit 134 when the user communicates with the chip 30 of the second medium. It is possible to prevent unintended processing from being performed.
