  Hereinafter, the automatic ticket gate according to the embodiment will be described with reference to the drawings. The automatic ticket gate is installed, for example, at a railway station, and permits or prohibits the passage of users. In the following description, as an example of the “medium” that can be processed by the automatic ticket gate, a traffic-based IC card and a paper ticket on which a display object such as a two-dimensional code is printed are illustrated. The medium may be an electronic medium such as a mobile phone having the same settlement function as a traffic IC card. Further, the "medium" corresponding to a paper ticket may be an electronic medium such as a mobile phone having a function of displaying a display object. For example, an ID (identification information) of an entrance station, a charge balance of electronic money, and the like are stored in a traffic IC card. Paper tickets are issued from, for example, a ticket vending machine installed at a station. At this time, a display object in which information encoded (encrypted) including the amount of money purchased at the time of ticket issue and the ID of the station where the ticket vending machine is installed (that is, the ID of the boarding station) is printed Etc. Note that, instead of the ID of the boarding station and the amount of money, a display object obtained by encoding an accessible section (for example, from A station to B station) may be printed on the paper ticket. The display object is, for example, a QR code (registered trademark). The display object may be a one-dimensional code such as a bar code, and may be in any form as long as information necessary for the determination of passability is encoded.

  FIG. 1 is a view of the automatic ticket gate 1 of the embodiment as viewed from above. The automatic ticket gate 1 includes a master unit 10 and a slave unit 30 disposed opposite to each other across a passage. The main unit 10 includes, for example, a reading unit 11, a top display unit 12, a front display unit 13, door units 14 and 15, and a control unit 20. Also, the slave unit 30 includes a reading unit 31, an upper surface display unit 32, a front display unit 33, and door units 34 and 35.

  The reading unit 11 of the main unit 10 reads and reads the information stored in the IC card or the information encoded in the display object printed on the paper ticket, which has been deceived by the user trying to pass in the direction a in FIG. The transmitted information is transmitted to the control unit 20. Further, the reading unit 11 writes the result of the stored fare (SF) process, that is, the toll collection process from the electronic money by the control unit 20 in the IC card. The reading unit 11 includes, for example, an antenna (not shown), and performs wireless communication with the IC card using a 13.56 [MHz] frequency band. The upper surface display unit 12 displays the result processed by the control unit 20 when the IC card or the paper ticket is flipped by the reading unit 11. The front display unit 13 displays a mark, a figure, a character or the like indicating whether or not it is possible to pass in the direction a in FIG. The display content of the front display unit 13 or the presence or absence of the display is determined by the control unit 20.

  On the other hand, the reading unit 31 of the slave machine 30 stores the information stored in the IC card or the information encoded in the display object printed on the paper ticket, which has been deceived by the user trying to pass in the direction b in FIG. The read information is sent to the control unit 20 of the main unit 10. In addition, the reading unit 31 writes the result of the SF processing performed by the control unit 20 of the main unit 10 in the IC card after the IC card is deceived. The upper surface display unit 32 displays the result processed by the control unit 20 of the main machine 10 when the IC card or the paper ticket is flipped by the reading unit 31. The front display unit 33 displays a mark, a figure, a character or the like indicating whether or not it is possible to pass in the direction b in FIG. The display content of the front display unit 33 or the presence or absence of the display is determined by the control unit 20 of the main unit 10.

  The control unit 20 of the main unit 10 maintains the door portions 15 and 35 in the open state when the automatic ticket gate 1 is set to the operation mode for permitting the passage of the user in the direction a in FIG. By controlling the door parts 14 and 34 in the open or closed state, the passage of the user in the direction a is permitted or prohibited. Further, when the automatic ticket gate 1 is set to the operation mode for permitting the passage of the user in the direction b in FIG. 1, the control unit 20 maintains the doors 14 and 34 in the open state, and By controlling the door parts 15 and 35 in the open or closed state, the passage of the user in the b direction is permitted or prohibited.

  Further, the operation mode of the automatic ticket gate 1 may include an operation mode which permits both passage in the direction a and passage in the direction b in FIG. 1. In this case, the control unit 20 of the main unit 10 causes, for example, control to display a mark, a figure, a character, etc. indicating permission of passage on both the front display unit 13 and the front display unit 33 unless the user is passing. I do. In addition, for example, when the user enters from either side and the medium of the IC card or the paper ticket is stolen by either one of the reading unit 11 and the reading unit 31, the control unit 20 is the other reading unit. Is controlled, and control is made to display a mark, a figure, a character, or the like indicating prohibition of passage on the display unit (front display unit 13 or front display unit 33) on the side where the user has not entered.

  In FIG. 1, the automatic ticket gate 1 has been described as an IC card and a paper ticket on which a display object is printed (or an electronic device for displaying a display object). However, the automatic ticket gate 1 further , And may be capable of processing magnetic tickets. Moreover, the automatic ticket gate 1 is not limited to one that allows the user to pass in both directions, but may be one that is configured by a main unit and an auxiliary unit and that allows the user to pass in only one direction. In the following embodiment, although it is described as the automatic ticket gate 1 capable of using the IC card and the paper ticket on which the display object is printed, only the paper ticket on which the display object is printed can be used. It may be an automatic ticket gate 1.

  FIG. 2 is a top view of the reading unit 11 of the automatic ticket gate 1 of the embodiment. The reading unit 11 includes a touch detection sensor Sc, a reader / writer 16, and a camera 17. The touch detection sensor Sc is formed in a panel shape, and has a detection surface that detects whether a part (for example, a hand) of the user's body has touched. The touch detection sensor Sc generates a detection signal indicating that the detection surface is touched when the user touches the detection surface of the panel with the IC card or the paper ticket to the reading unit 11. Do. Thereby, the touch detection sensor Sc detects that the medium is read by the reading unit 11 by the user. The touch detection sensor Sc is a touch panel of, for example, a resistive film type, a surface acoustic wave type, an electromagnetic induction type, an electrostatic capacitance type, or the like. The touch detection sensor Sc is a transparent (or semi-transparent) panel capable of transmitting visible light, and enables imaging of a display object transmitted therethrough. The automatic ticket gate 1 may have a configuration for detecting that the medium has been stolen by the user by the reading unit 11 with an infrared sensor, a stereo camera, or the like, instead of the touch detection sensor Sc.

  The reader / writer 16 and the camera 17 are provided, for example, on the back side of the detection surface of the touch detection sensor Sc. The reader / writer 16 acquires information from the IC card through the touch detection sensor Sc. Further, the reader / writer 16 writes information to the IC card via the touch detection sensor Sc in accordance with the processing of the control unit 20 described later.

  The camera 17 picks up a display object printed on a paper ticket through the touch detection sensor Sc. The camera 17 is configured of, for example, an image sensor such as a charge-coupled device (CCD) or a complementary metal oxide semiconductor (CMOS). The configuration of the reading unit 11 shown in FIG. 2 may be applied to the reading unit 31 of the slave 30 in the same manner. That is, the reading unit 31 may be configured to include the touch detection sensor Sc, the reader / writer 36, and the camera 37.

  FIG. 3 is a view of the main unit 10 of the automatic ticket gate 1 of the embodiment as viewed from the passage side. In addition to the reading unit 11 and the door units 14 and 15 described above, the main unit 10 further includes a transmissive photoelectric sensor St and a reflective photoelectric sensor Sr. For example, among the housing surfaces of the main unit 10, a plurality of (26 in the case of the example of FIG. 3) transmission-type photoelectric sensors St are provided at equal intervals on the housing surface on the passage side. In the present embodiment, a transmission type photoelectric sensor St functioning as a light projector and a transmission type photoelectric sensor St functioning as a light receiver are used as a pair. For example, when the transmission type photoelectric sensor St provided in the main unit 10 is a light projector, the transmission type photoelectric sensor St provided in the slave unit 30 functions as a light receiver. The transmission type photoelectric sensor St provided on the side of the slave unit 30 receives the projection light emitted from the transmission type photoelectric sensor St on the main unit 10 side when there is no device for blocking light in the passage. On the other hand, when a user is present in the passage, the projected light emitted from the transmission type photoelectric sensor St is blocked by the user. Therefore, the transmission type photoelectric sensor St on the slave unit 30 side does not receive the projection light emitted from the transmission type photoelectric sensor St. The control unit 20 described later obtains a detection signal from the transmission type photoelectric sensor St and determines whether or not a person is in the passage. For example, when the control unit 20 acquires a detection signal generated when the projection light is not received from the transmissive photoelectric sensor St, the control unit 20 determines that there is no user blocking the projection light in the passage, and the projection light When a detection signal generated when light is received is obtained from the transmission type photoelectric sensor St, it is determined that there is a user who blocks the projection light in the passage.

  Similar to the transmission type photoelectric sensor St, for example, a plurality of reflection type photoelectric sensors Sr are equally spaced on the passage side of the partition projecting upward from the casing of the main unit 10 (in the case of the example of FIG. 3) provided. The reflective photoelectric sensor Sr projects light in a predetermined direction. The reflective photoelectric sensor Sr projects light and then receives light reflected from the direction in which the light is projected. The reflective photoelectric sensor Sr generates a detection signal indicating whether or not the user's body that reflects the light exists in the passage based on the intensity of the received light. For example, the reflection type photoelectric sensor Sr generates a detection signal indicating that the user is not present in the passage when the intensity of the received light is less than the threshold, and when the intensity of the received light exceeds the threshold, the passage It generates a detection signal indicating that the user is present. The reflective photoelectric sensor Sr is mainly used to determine whether the user present in the passage is an adult or a child. Although the above-described reflection type photoelectric sensor Sr has been described as being provided to the main unit 10, the present invention is not limited thereto. The reflection type photoelectric sensor Sr may be provided to the sub unit 30 or may be provided to both the main unit 10 and the sub unit 30 Good. The reflective photoelectric sensor Sr or the transmissive photoelectric sensor St is an example of the “second detection unit”.

  The following description will be given focusing on the case where the medium is picked up by the reading unit 11 on the main unit 10 side. The description of the case where the medium is picked up by the reading unit 31 of the slave device 30 will be omitted. FIG. 4 is a diagram showing an example of a functional configuration of the automatic ticket gate 1 of the embodiment. The automatic ticket gate 1 further includes an encoding / decoding unit 18, an image processing unit 19, a storage unit 25, and a speaker 26. Further, the control unit 20 includes an acquisition unit 21, an SF processing unit 22, and a paper ticket processing unit 23.

  Each functional unit included in the control unit 20 is, for example, a software functional unit that functions when a processor such as a central processing unit (CPU) executes a program stored in a program memory. In addition, some or all of the functional units included in the control unit 20 may be hardware functional units such as a large scale integration (LSI) or an application specific integrated circuit (ASIC). Also, the encoding / decoding unit 18 and the image processing unit 19 may be software function units implemented by the processor of the control unit 20. The camera 17 and the image processing unit 19 described above are examples of the “optical reading unit”, and the touch detection sensor Sc is an example of the “detection unit”. Further, a part or all of the upper surface display units 12 and 32 and the speaker 26 is an example of the “output unit”.

  The encode / decode unit 18 decrypts the information read from the IC card by the reader / writer 16 and outputs it to the control unit 20, and encrypts the information instructed by the control unit 20 and outputs it to the reader / writer 16. In response to this, the reader / writer 16 writes the information input from the encoding / decoding unit 18 into the IC card.

  The image processing unit 19 extracts a display object from the image captured by the camera 17, and decodes the extracted display object into information such as numerical values and characters.

  The storage unit 25 is, for example, a ROM (Read Only Memory) or a flash memory. The storage unit 25 stores a fare table and the like described later. The speaker 26 outputs an audio according to the instruction of the control unit 20.

  The acquisition unit 21 acquires detection signals from the touch detection sensor Sc, the transmissive photoelectric sensor St, and the reflective photoelectric sensor Sr, and acquires processing results from the encode / decode unit 18 and the image processing unit 19. The acquisition unit 21 outputs the acquired detection signal and information to the SF processing unit 22 or the paper ticket processing unit 23.

  When the medium read by the reading unit 11 is an IC card, the SF processing unit 22 performs the following process. The SF processing unit 22 performs SF processing based on the charge balance of the electronic money held by the IC card. Specifically, when performing the entrance process, the SF processing unit 22 extracts the charge balance of the electronic money from the information stored in the IC card read by the reader / writer 16, and the extracted charge balance corresponds to the first fare If it is more than the amount of money, the passage of the user is permitted, and if it is less than the initial fare, the passage of the user is prohibited.

  On the other hand, when the participation processing is performed, the SF processing unit 22 extracts the ID of the entrance station and the charge balance of the electronic money from the information stored in the IC card read by the reader / writer 16. The SF processing unit 22 derives the necessary fare by searching the fare table using the extracted entry station ID. The fare table is, for example, information in which an ID of an entrance station (or boarding station) and a fare necessary for boarding from the entrance station (or boarding station) to the station (local station) are associated.

  Then, when the derived amount is less than the charge balance, the SF processing unit 22 permits the user to pass and the encoding / decoding unit 18 to write the amount obtained by subtracting the derived amount from the charge balance into the IC card. And instructs the reader / writer 16. The SF processing unit 22 prohibits the user from passing if the derived amount exceeds the charge balance. When permitting passage of the user, the SF processing unit 22 controls the door units 14 and 34 in the open state. When the passage of the user is prohibited, the SF processing unit 22 controls the door units 14 and 34 to be in the closed state, and indicates that the top display unit 12 and / or the speaker 26 has a shortage of electronic money charge balance. Output information.

  When the medium which has been read by the reading unit 11 is a paper ticket, the paper ticket processing unit 23 performs the following process. When performing the entrance process, the paper ticket processing unit 23 determines whether the information decoded from the display object of the paper ticket is valid. If the information decrypted from the paper ticket display object is valid, the paper ticket processing unit 23 permits the user to pass, and if the information decrypted from the paper ticket display object is not valid, Prohibit the passage of users.

  On the other hand, when performing the participation process, the paper ticket processing unit 23 extracts the ID of the boarding station and the purchase price of the paper ticket from the information decrypted from the display object of the paper ticket. The paper ticket processing unit 23 derives the necessary fare by searching the fare table using the extracted ID of the boarding station. Then, when the derived fare is equal to or less than the purchase price of the paper ticket, the paper ticket processing unit 23 permits the passage of the user, and when the derived fare is less than the purchase price of the paper ticket, the passage of the user Ban.

  When the user's passage is permitted, the paper ticket processing unit 23 controls the doors 14 and 34 in the open state, and at the same time, displays information to prompt the user to insert the paper ticket into a paper ticket collection box (not shown). It is output to the display unit 12 and / or the speaker 26. When the passage of the user is prohibited, the paper ticket processing unit 23 controls the door units 14 and 34 to be in the closed state and causes the top display unit 12 and / or the speaker 26 to output information to the effect that it is out of the purchase section. .

  In addition, the paper ticket processing unit 23 detects the position of the user in the passage based on the detection signals of the touch detection sensor Sc and the transmission photoelectric sensor St. Specifically, when any one or more of the transmission type photoelectric sensors St detect the user, the paper ticket processing unit 23 determines that the user has entered the passage. Furthermore, the paper ticket processing unit 23 is a transmission type photoelectric sensor St closest to the reading unit 11 side where the medium is scooped by the user, that is, a transmission type photoelectric sensor St closest to the entrance side (the rightmost transmission in FIG. When the photo sensor St) detects a user, it is determined that the user has entered the passage, and when the user enters a predetermined position in the passage with the passage of the user not permitted, the door portion 14 and 34 are controlled to be in the closed state, and the operation of the reading unit 11 is stopped or the operation of the paper ticket processing unit 23 is stopped until the user moves backward and is not detected by the touch detection sensor Sc or the transmission photoelectric sensor St. Stop it. Hereinafter, such a state is referred to as a “judged as being free of bill” state.

  Drawing 5 is a figure showing an example of the position where automatic ticket gate 1 of an embodiment performs a bill-free determination. In the example of FIG. 5, it is assumed that the user passes the passage in the direction of the arrow (left direction in the figure). The “predetermined position in the passage” is set to, for example, a position P1 shown in the drawing. It is determined that the bill is not billed if the user proceeds without disturbing the medium to the reading unit 11 or if the user has tampered with the medium to the reading unit 11 but the information is not read normally It is. When the bill-free determination is made, the user has to fled the medium to the reading unit 11 after leaving the passage of the automatic ticket gate 1 once in order to cause the automatic ticket gate 1 to cancel the bill-free determination. As a result, the determination of no bill may hinder the smooth passage of the user.

  Therefore, when the touch detection sensor Sc detects that the medium is fed to the reading unit 11, the paper ticket processing unit 23 starts counting time, and the reading unit 11 permits the passage of the user. If the timed time exceeds a predetermined time without being read, information indicating that the information is not obtained from the medium is output to the top display unit 12 and / or the speaker 26. Hereinafter, information indicating that information is not obtained from the medium will be referred to as “alarm information”. Thus, the automatic ticket gate 1 can prevent the user from advancing to the position P1 in a state where the information for passing is not read, and can prompt the reading unit 11 to scan the medium. .

  Hereinafter, with reference to FIG. 6, a flow of processing capable of notifying the user that information can not be read from the medium before performing the free ticket determination will be described. FIG. 6 is a flowchart showing an example of the flow of processing executed by the control unit 20 of the embodiment.

  First, the control unit 20 determines whether the user has entered the passage of the automatic ticket gate 1 (step S100). For example, when any one or more of the transmission type photoelectric sensors St detect the user, the control unit 20 determines that the user has entered the passage. If it is determined that the user has not entered the passage of the automatic ticket gate 1, the processing of one routine of this flowchart ends.

  If the control unit 20 determines that the user has entered the passage of the automatic ticket gate 1, the control unit 20 determines whether the passability determination process has already been performed for the user (step S102). The “passability determination process” refers to the determination process for permitting or prohibiting the user's passage, which is executed by the SF processing unit 22 or the paper ticket processing unit 23 as described above.

  When the determination processing of the passability is already performed, the control unit 20 performs processing (pass processing) for permitting or prohibiting the user's passage according to the determination result (step S104). Thus, the processing of one routine of this flowchart ends.

  Note that, in order to perform the process of step S102 described above, the control unit 20 performs the determination using, for example, a binary flag to indicate whether the process of determining whether to pass is already performed. Specifically, the control unit 20 stores, for example, a flag value of “1” in the storage unit 25 when performing the passability determination process (steps S118 and S134 described later). The value is held in the storage unit 25. Thereafter, the control unit 20 refers to the value of the flag stored in the storage unit 25 to determine whether the determination processing for determining passability is already performed. The control unit 20 rewrites the value of the flag stored in the storage unit 25 from “1” to “0” when it is determined in the process of step S102 that the passability determination process has already been performed.

  If the passability determination process has not yet been performed for the user, the paper ticket processing unit 23 determines whether the user is detected by the transmissive photoelectric sensor St provided at the position P1 (step S106). ). That is, the paper ticket processing unit 23 determines whether or not the user has advanced the passage to the position P1 where the sensor that is the trigger for the free ticket determination is provided.

  When the user is detected by the transmission type photoelectric sensor St provided at the position P1, the paper ticket processing unit 23 determines that the paper is not billed (step S108), and controls the door units 14 and 34 in the closed state. And causes the top display 12 and / or the speaker 26 to output error information. The error information is information that is output when it is determined that the bill is unpaid, and is, for example, information different from the above-described alarm information. This enables the automatic ticket gate 1 to urge the user to leave the passage.

  Next, the paper ticket processing unit 23 determines whether the user has left the passage of the automatic ticket gate 1 based on the detection signal of the transmission type photoelectric sensor St (step S110). Specifically, in the paper ticket processing unit 23, the transmission type photoelectric sensor St located closer to the reading unit 11 than the transmission type photoelectric sensor St provided at the position P1 detects the user again, and then all the transmission type photoelectric sensors When the sensor St no longer detects the user, it is determined that the user has left the passage. In the case of the example of FIG. 5 described above, the paper ticket processing unit 23 detects the user by the transmission type photoelectric sensor St provided at the position P2 as a sensor close to the reading unit 11 side, and thereafter all the transmission type photoelectric sensors When the user is not detected by St, it is determined that the user has left the passage.

  When it is determined that the user has left the passage, the paper ticket processing unit 23 cancels the non-tag determination (step S112), controls the doors 14 and 34 from the closed state to the open state, and outputs error information. Control the top display 12 and / or the speaker 26 so as to stop the As a result, the processing of one routine of this flowchart ends. When the user does not leave the passage, the paper sheet handling unit 23 stands by until it is determined that the user has left the passage.

  On the other hand, when the user is not detected by the transmission type photoelectric sensor St provided at the position P1, the SF processing unit 22 determines whether communication with the medium read by the reading unit 11 is established (step S114). . When communication with the medium read by the reading unit 11 is established, the SF processing unit 22 determines that the medium is an IC card (step S116), and performs an SF process based on the information stored in the IC card. Next, the control unit 20 determines whether or not the user can pass according to the result of the SF processing (step S118), and ends the processing of this flowchart.

  On the other hand, when communication with the medium passed through the reading unit 11 is not established, the paper ticket processing unit 23 determines that the medium is a paper ticket on which the display object is printed (step S120). Next, the paper ticket processing unit 23 determines whether the detection surface of the touch detection sensor Sc has been touched by the user with reference to the detection signal acquired from the touch detection sensor Sc (step S122). When the detection surface is not touched, the paper ticket processing unit 23 determines whether the user has left the passage based on the detection signal of the transmission type photoelectric sensor St as in the process of step S110 ( Step S124). When it is determined that the user has not left the passage, the paper ticket processing unit 23 returns the process to step S102, and when it is determined that the user has left the passage, the processing of one routine of this flowchart ends. .

  On the other hand, when it is determined that the detection surface of the touch detection sensor Sc is touched, the paper ticket processing unit 23 starts clocking (step S126). The clocking may be performed by software processing or may be performed using a timer (not shown). Next, the paper ticket processing unit 23 determines whether or not a predetermined time has elapsed since the start of clocking (step S128). When it is determined that the predetermined time has elapsed since the start of clocking, the paper ticket processing unit 23 controls the upper surface display unit 12 and / or the speaker 26 to output alarm information (step S130).

  Here, for example, the predetermined time T is set to a time shorter than the value obtained by dividing the above-described distance X [km] between the position P1 and the position P2 by the average walking speed Va [km / h] of the user. Be done. The average walking speed Va is, for example, 4 [km / h] which is said to be the average walking speed of human beings. Therefore, the predetermined time T [h] is a time that satisfies the condition represented by the equation (1). When the predetermined time T is represented by [min] and the distance X is represented by [m], the predetermined time T [min] is represented by equation (2). Note that the setting operation of the predetermined time T may be accepted from the operator by an input operation unit (not shown). In this way, it is possible to adjust the predetermined time T to be short in areas where the user's walking speed is fast and to set the predetermined time T long in areas where the user's walking speed is slow.

  T <X / 4 (1)

  T <(X / 4) × 60 × 60/1000 (2)

  By this, it is possible to increase the possibility that the paper ticket processing unit 23 outputs the alarm information before the ticket free determination in step S138 described later is performed. As a result, it is possible to increase the possibility that the automatic ticket gate 1 can prompt the user to turn back the passage before reaching the position (the position P1 in FIG. 5) at which the user does not check the bill. If the predetermined time has not elapsed since the start of clocking, the paper ticket processing unit 23 skips the process of step S130.

  Next, the paper ticket processing unit 23 determines whether the information obtained by decoding the display object can be acquired from the image processing unit 19 (step S132). When the paper ticket processing unit 23 can acquire the information obtained by decoding the display object from the image processing unit 19, the paper ticket processing unit 23 determines whether the user can pass or not based on the acquired information (step S134).

  If the paper ticket processing unit 23 can not acquire the decoded information of the display object from the image processing unit 19, the user may be detected by the transmission type photoelectric sensor St provided at the position P1, as in the process of step S106. It is determined whether or not (step S136). When the user is detected by the transmission type photoelectric sensor St provided at the position P1, the paper ticket processing unit 23 determines that the bill is unpaid as in the process of step S108 (step S138). And 34 are closed, and error information is output to the top display 12 and / or the speaker 26. Next, as in the process of step S110, the paper ticket processing unit 23 determines whether the user has left the passage based on the detection signal of the transmission type photoelectric sensor St (step S140).

  On the other hand, when the user is not detected by the transmission type photoelectric sensor St provided at the position P1, the paper ticket processing unit 23 similarly to the processing of step S110 and step S140, based on the detection signal of the transmission type photoelectric sensor St. It is determined whether the user has left the passage (step S142).

  If it is determined in step S142 that the user has not left the passage, the paper ticket processing unit 23 determines whether a predetermined time has elapsed since the start of clocking (step S148). If a predetermined time has elapsed since the start of clocking, the paper ticket processing unit 23 returns the process to step S132. If the predetermined time has not elapsed since the start of clocking, the process returns to step S128.

  On the other hand, if the paper ticket processing unit 23 determines that the user has left the passage as a result of processing in step S140 after the process of step S134, or determines that the user has left the passage as a result of processing in step S142. If it is determined that the clocking is finished, the clocking result is initialized (step S144). The initialization is, for example, setting the count time at the time of clocking to “0”. Next, the paper ticket processing unit 23 cancels the non-tag determination (step S146), controls the doors 14 and 34 from the closed state to the open state, and stops the output of the alarm information. And / or control the speaker 26. As a result, the control unit 20 ends the processing of one routine of this flowchart.

  As a result of the process described above, the automatic ticket gate 1 generates alarm information by the time the user reaches the position P1 at which the bill is not judged when the medium is stolen by the user but the information could not be read. Output. As a result, it is assumed that the user promptly retracts the passage and sends the medium to the reading unit 11 again. As a result, the automatic ticket gate 1 can suppress the occurrence of a delay due to the bill-free determination process.

  FIG. 7 is a state transition diagram showing an example of the change of the operation state of the control unit 20 of the embodiment. As a result of the process of the flowchart shown in FIG. 6 described above, the state transition shown in FIG. 7 is realized. The control unit 20 shifts to a state (step S200) of determining whether or not the user has entered the passage based on, for example, a detection signal of the transmission type photoelectric sensor St.

  From the operation state of step S200, for example, the control unit 20 obtains no information based on the state of acquiring information of the display object decoded from the image processing unit 19 (step S202) and the detection signal of the transmissive photoelectric sensor St. Any one of a state of determining whether or not there is (step S204) and a state of determining whether or not the detection surface is touched by the user based on the detection signal of the touch detection sensor Sc (step S206) Transition to one operation state.

  When the paper ticket processing unit 23 shifts to the state of step S202, it shifts to a state (step S208) of performing the passability determination processing based on the acquired display object decryption information.

  Further, when it is determined that the bill is not billable in the state of step S204, the control unit 20 controls the doors 14 and 34 to be closed so as to prohibit passage of the user, and the error information is displayed on the upper surface display unit 12 And / or shift to a state in which the speaker 26 is made to output (step S210).

  Further, when it is determined that the detection surface is touched in the state of step S206, the paper ticket processing unit 23 shifts to a state of starting clocking (step S212).

  After the clocking is started, the paper ticket processing unit 23 further obtains a state of acquiring the information of the display object decoded from the image processing unit 19 (step S214), and based on the detection signal of the transmission type photoelectric sensor St And one of the operating states (step S218) for determining whether or not a predetermined time has elapsed.

  When the paper ticket processing unit 23 shifts to the state of step S214, as in the operation state of step S208 described above, the state of performing the passability determination process based on the acquired information of the display object (step S220) Transition.

  Further, as in the operation state of step S210 described above, when it is determined that the bill is not billable in the state of step S216, the paper ticket processing unit 23 closes the door portions 14 and 34 so as to prohibit passage of the user. In addition to the state control, the state shifts to a state in which error information is output to the top display 12 and / or the speaker 26 (step S222).

  In addition, when the predetermined time passes in the state of step S218, the paper ticket processing unit 23 shifts to a state of outputting alarm information to the upper surface display unit 12 and / or the speaker 26 (step S224). As a result, although the automatic ticket gate 1 receives a paper ticket to the reading unit 11 by the user, when the control unit 20 can not normally acquire information, alarm information is sent to the top display unit 12 and / or the speaker 26. By outputting, it is possible to notify the user that the information has not been read from the medium. As a result, the automatic ticket gate 1 can prompt the user to read the medium to the reading unit 11 again. In addition, when the predetermined time is set so that the alarm information is output before the bill-free determination, the automatic ticket gate 1 can read the information from the medium to the user before the bill-free determination. Can be notified.

  According to at least one embodiment described above, the camera 17 and the image processing unit 19 optically acquire information from the display object displayed on the medium shook by the user, and the touch detection sensor Sc detects the information on the camera 17. The controller 20 starts timing when detecting that the medium is being deceased, and displays alarm information indicating that the information from the medium can not be acquired when the measured time exceeds a predetermined time. Output to the part 12 (32) and / or the speaker 26. By this, the automatic ticket gate 1 in the embodiment can urge the user to read the paper ticket to the reading unit 11 again before performing the ticket-free determination. As a result, the automatic ticket gate 1 according to the embodiment can reduce the frequency of the non-tag determination, and can suppress the decrease in processing capacity. Therefore, the automatic ticket gate 1 can maintain the rapid passage of the user.

  Further, according to the embodiment, by setting the timing of outputting the alarm information to a time that reflects the average walking speed of humanity, it is possible to read information from the medium to the user before making a bill-free determination. Can increase the possibility of being notified that the As a result, the automatic ticket gate 1 according to the embodiment can further reduce the frequency of performing the no-tag determination.
