Description

[Technical Field]

[0001] The present invention relates to a technique for restricting the passage of users through a passage by opening and closing a door provided in the passage. [Background technology]

[0002] Conventionally, gate devices have been used in various locations, such as ticket gates at train stations and entrances and exits at facilities (theme parks, office buildings, security areas, etc.), to restrict the passage of users through passageways by opening and closing doors installed in the passageways.

[0003] For example, at a station ticket gate, an automatic ticket gate (gate device) performs ticket screening processing for users entering and exiting the station. As is well known, an automatic ticket gate accepts a ticket held by a user passing through the ticket gate passage and reads the ticket information recorded on the ticket. Based on the ticket information that it reads, the automatic ticket gate determines whether or not to permit the user to pass through the ticket gate passage, and depending on the result of the determination, opens or closes doors provided in the ticket gate passage to restrict the user's passage.

[0004] Recently, there are also automatic ticket gates that identify users using facial recognition, fingerprint recognition, etc., and determine whether or not to allow the user to pass through the ticket gate passage.

[0005] Some automatic ticket gates are equipped with a locking mechanism that prevents the doors from being shifted from a closed state to an open state by external forces, in order to prevent unauthorized passage of users who have been determined not to be allowed to pass through the passage (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2020-80109 A Summary of the Invention [Problem to be solved by the invention]

[0007] The automatic ticket gate in Patent Document 1 is configured to unlock the door by the locking mechanism when it detects that an external force exceeding a certain level has been applied to the closed door. In other words, the automatic ticket gate in Patent Document 1 is not configured to prevent a door in a locked state from being subjected to a relatively large external force. Therefore, the automatic ticket gate in Patent Document 1 has the risk of the door being deformed by an external force applied when it is in a locked state.

[0008] An object of the present invention is to provide a technology that can sufficiently prevent a door from being deformed by an external force applied when the door is in a closed state. [Means for solving the problem]

[0009] In order to achieve the above object, the gate device of the present invention is configured as follows.

[0010] The gate device of the present invention can be used, for example, as an automatic ticket gate installed at a ticket gate at a station, or as an entrance / exit gate (including a security gate) installed at the entrance or exit of a facility (such as a theme park, office building, or security area).

[0011] The determination unit determines whether to allow a user who has entered the passage to pass. The door opening / closing control unit controls the opening and closing of a door provided in the passage according to the determination result of the determination unit. The lock control unit controls the state of the lock mechanism unit. The lock control unit controls the lock mechanism unit to switch between a locked state, which prevents the door from being shifted from a closed state to an open state by an external force, and an unlocked state, which does not prevent the door from being shifted from a closed state to an open state by an external force. The speed detection unit detects the movement speed of the user. Then, the lock control unit controls the lock mechanism unit to the unlocked state when the movement speed of the user detected by the speed detection unit exceeds a predetermined first speed.

[0012] With this configuration, when there is a high possibility that a user will collide with the closed door, the door's locked state can be released (unlocked). Therefore, even if a user is unable to stop in front of the closed door and collides with it, the lock is released before the user collides, so the magnitude of the external force applied to the door due to the user's collision can be reduced. This makes it possible to sufficiently prevent the door from being deformed by the applied external force.

[0013] Furthermore, the detection of the user's speed may be configured to obtain the user's movement speed from, for example, a change in the distance to the user detected by a distance sensor, or may be configured to obtain the user's movement speed from a change in the user's position detected by multiple user detection sensors lined up along the user's direction of movement in the corridor, or may be configured in some other way.

[0014] For example, in a configuration using a distance measurement sensor, the user's movement speed can be obtained before the user enters the passage, allowing the lock control unit to smoothly control the release of the lock state. Furthermore, in a configuration using multiple user detection sensors aligned along the direction of user movement in the passage, the user's movement speed can be obtained with an existing configuration, so by modifying the control software, it can be applied to existing gate devices and the cost of building a system can be reduced. Furthermore, the user's movement speed can be detected using, for example, millimeter-wave radar, ultrasonic sensors, infrared sensors, or TOF (Time Of Flight) cameras, or by image processing.

[0015] Furthermore, the door opening / closing control unit may be configured to open the door provided in the passageway if the moving speed of the user detected by the speed detection unit exceeds a second speed that is higher than the first speed. With this configuration, the frequency with which users collide with the door can be further reduced, and deformation of the door can be further suppressed.

[0016] Furthermore, for example, the door opening / closing control unit may be configured to open a door provided in the passageway after the distance between the user and the door in a closed state reaches a set distance if the user's moving speed detected by the speed detection unit exceeds a second speed that is faster than the first speed.

[0017] The door may be provided in the middle of the passage between the entrance and exit for users, or may be provided on the exit side for users passing through the passage. [Effects of the Invention]

[0018] According to this invention, it is possible to sufficiently reduce the frequency with which the door is deformed by an external force applied when the door is in the closed state. [Brief explanation of the drawings]

[0020] Hereinafter, an embodiment of the present invention will be described.

[0021] <1. Application Examples> FIG. 1(A) is a diagram showing a schematic external view of the automatic ticket gate of this example, and FIG. 1(B) is a plan view of the direction A shown in FIG. 1. In this example, the automatic ticket gate 1 corresponds to the gate device of the present invention. The automatic ticket gate 1 performs ticket screening processing for at least one of users entering a station premises and users exiting the station premises. For example, if the direction A shown in FIG. 1 is the direction entering the station premises and the direction B shown in FIG. 1 is the direction exiting the station premises, the direction of passage of users through the ticket gate passage of the automatic ticket gate 1 may be only the direction A, only the direction B, or even both the directions A and B.

[0022] The automatic ticket gate 1 reads the ticket information on the ticket presented by the user and determines whether to permit the user to pass through the passageway based on the read ticket information. The ticket may be a magnetic ticket with a magnetic sheet attached, a contactless IC card with wireless communication capabilities, or an optically readable ticket with an optically readable code such as a two-dimensional barcode (e.g., QR Code (registered trademark)) printed on its face. These types of tickets are already known, so a description thereof will be omitted here.

[0023] In this example, for simplicity, the automatic ticket gate 1 is described as being configured to accept a contactless IC card as a ticket. However, the automatic ticket gate 1 may be configured to accept a magnetic ticket or an optically readable ticket as a ticket, or may be configured to accept two or more of a contactless IC card, a magnetic ticket, and an optically readable ticket as a ticket.

[0024] In this example, automatic ticket gate 1 has antennas 3 (3a, 3b) on both sides of the ticket gate passage. Automatic ticket gate 1 communicates wirelessly with a contactless IC card held over antenna 3, reading the ticket information recorded on the contactless IC card and writing the ticket information to the contactless IC card. In Fig. 1, a user entering the station holds his / her contactless IC card over antenna 3a, and a user leaving the station holds his / her contactless IC card over antenna 3b.

[0025] If the direction of passage of users through the ticket gate is one, one of the antennas 3 (3a or 3b) does not need to be provided.

[0026] The automatic ticket gate 1 determines whether to allow a user to pass through the ticket gate passage based on the ticket information read from a contactless IC card that the user holds over the antenna 3. The automatic ticket gate 1 also calculates the user's moving speed from changes in the user's position over time detected by the distance measurement sensor 5. The position of a user entering the station is detected by the distance measurement sensor 5a shown in Fig. 1, and the position of a user leaving the station is detected by the distance measurement sensor 5b shown in Fig. 1.

[0027] In addition, when the direction of travel of users through the ticket gate passage is one direction, one of the distance measuring sensors 5 (5a or 5b) does not have to be provided. The installation position of distance measuring sensor 5 is not limited to the position shown in Fig. 1, and may be any position as long as it is a position where the distance to the user can be measured.

[0028] When the automatic ticket gate 1 determines that the user is permitted to pass through the ticket gate passage, it opens the doors 2 (2a, 2b). On the other hand, when the automatic ticket gate 1 determines that the user is not permitted to pass through the ticket gate passage, it closes the doors 2 (2a, 2b). Figure 1 shows the state in which the doors 2 are closed.

[0029] Furthermore, when the automatic ticket gate 1 closes the door 2, it controls the state of the locking mechanism to a locked state that prevents the door 2 from being shifted from a closed state to an open state due to an external force. The locking mechanism is a mechanism that physically restricts the rotation of the door 2. For example, the locking mechanism is configured to use an actuator such as a solenoid to move a locking member (e.g., a stopper) between a position that prevents the rotation of the rotation shaft of the door 2 (locked position) and a position that does not prevent the rotation of the rotation shaft of the door 2 (unlocked position). The locking mechanism may have, for example, the configuration disclosed in the above-mentioned Patent Document 1, or any other known configuration. The locking mechanism may also have a configuration that does not include an actuator. Since various configurations of the locking mechanism are known, a description thereof will be omitted here.

[0030] When the automatic ticket gate 1 determines that the user is not permitted to pass through the ticket gate passage, it detects the user's moving speed. If the user's moving speed exceeds a predetermined first speed, the automatic ticket gate 1 unlocks the locking mechanism. In this case, even if the automatic ticket gate 1 unlocks the locking mechanism, it does not move the door 2 to an open state. The first speed may be set to, for example, the lower limit of the speed at which the user is predicted to collide with the closed door 2 (this does not necessarily mean that the user will collide with the door 2).

[0031] In this way, when the automatic ticket gate 1 predicts that a user who has been determined not to be permitted to pass through the ticket gate passage will collide with the closed door 2, it unlocks the locking mechanism, thereby softening the impact even if the user collides with the door 2. Furthermore, even when the automatic ticket gate 1 unlocks the locking mechanism, it does not transition the door 2 to the open state, so it can make the user aware that the door 2 is closed. As a result, the user will decelerate in an attempt to stop in front of the door 2, thereby reducing the impact force applied by the user who collides with the door 2. Therefore, the automatic ticket gate 1 in this example can sufficiently prevent the door 2 from being deformed by an external force applied when it is in the closed state.

[0032] <2.Configuration example> 2 is a block diagram showing the configuration of the main parts of the automatic ticket gate 1 of this example. The automatic ticket gate 1 of this example includes a control unit 11, a ticket processing unit 12, a display unit 13, a distance measurement unit 14, a user detection unit 15, a door opening / closing mechanism unit 16, a locking mechanism unit 17, and a communication unit 18.

[0033] The control unit 11 controls the operation of each part of the main body of the automatic ticket gate 1. The control unit 11 also has a passage determination unit 21, a door opening / closing control unit 22, a lock control unit 23, and a speed detection unit 24. The passage determination unit 21, the door opening / closing control unit 22, the lock control unit 23, and the speed detection unit 24 that the control unit 11 has will be described later.

[0034] The ticket processing unit 12 has an antenna 3 (3a, 3b) and, by wireless communication with a contactless IC card held over the antenna 3, reads the ticket information recorded on the contactless IC card and writes the ticket information to the contactless IC card.

[0035] The display unit 13 has a display (not shown) and, in accordance with instructions from the control unit 11, causes the display to display guidance for the user.

[0036] The distance measurement unit 14 has the distance measurement sensors 5 (5a, 5b) described above. The distance measurement unit 14 inputs the distance to the user (the distance between the distance measurement sensor 5 and the user) measured at regular time intervals by the distance measurement sensors 5 to the control unit 11 as measurement data.

[0037] The user detection unit 15 has a plurality of photoelectric sensors lined up along the ticket gate passage, and tracks users passing through the ticket gate passage by detecting the position of the user passing through the ticket gate passage from the detection output of each photoelectric sensor. The photoelectric sensors may be of a reflective type or a transmissive type (a type in which a light-emitting element and a light-receiving element are arranged opposite each other across the ticket gate passage).

[0038] The door opening / closing mechanism 16 opens and closes the door 2 provided in the ticket gate passage in accordance with instructions from the control unit 11.

[0039] As described above, the locking mechanism 17 is a mechanism that prevents the door 2 provided in the ticket gate passage from being shifted from the closed state to the open state by an external force when the door 2 is in the closed state. The locking mechanism 17 switches between a locked state (a state in which the door 2 is prevented from being shifted from the closed state to the open state by an external force) and an unlocked state (a state in which the door 2 is not prevented from being shifted from the closed state to the open state by an external force) in accordance with instructions from the control unit 11.

[0040] The communication unit 18 communicates with a higher-level device such as a station server, etc. The communication unit 18 may be configured to communicate with the higher-level device wirelessly or via a wire.

[0041] Next, the passage determination unit 21, the door opening / closing control unit 22, the lock control unit 23, and the speed detection unit 24 included in the control unit 11 will be described.

[0042] Based on the ticket information read from the contactless IC card by the ticket processing unit 12, the passage determination unit 21 determines whether or not a user who holds this contactless IC card over the antenna 3 (3a, 3b) is permitted to pass through the ticket gate passage. If the passage determination unit 21 determines that the user is permitted to pass, it instructs the ticket processing unit 12 to write the ticket information related to the current ticket gate processing to the contactless IC card from which the ticket information was read. Once the passage determination unit 21 has completed writing the ticket information related to the current ticket gate processing to the contactless IC card from which the ticket information was read, it permits the user to pass through the ticket gate passage. In other words, if the passage determination unit 21 fails to write the ticket information related to the current ticket gate processing to the contactless IC card from which the ticket information was read (if a write error occurs), it does not permit the user to pass through the ticket gate passage.

[0043] When the passage determination unit 21 determines that the user is permitted to pass through the ticket gate passage, the door opening / closing control unit 22 instructs the door opening / closing mechanism unit 16 to open the door 2. When the passage determination unit 21 determines that the user is not permitted to pass through the ticket gate passage, the door opening / closing control unit 22 instructs the door opening / closing mechanism unit 16 to close the door 2.

[0044] If the door 2 is already in an open state when the door opening / closing mechanism 16 receives an instruction to open the door 2 from the door opening / closing control unit 22, the door opening / closing mechanism 16 will not perform the opening / closing operation of the door 2 (it will close the door 2 once and will not open it again). Similarly, if the door 2 is already in a closed state when the door opening / closing mechanism 16 receives an instruction to close the door 2 from the door opening / closing control unit 22, the door opening / closing mechanism 16 will not perform the opening / closing operation of the door 2 (it will not open the door 2 once and will not close it again).

[0045] The lock control unit 23 instructs the lock mechanism unit 17 to switch between a locked state and an unlocked state.

[0046] If the lock mechanism 17 is already in the locked state when it receives an instruction to switch to the locked state from the lock control unit 23, it does not take any particular action in response to this instruction (it does not temporarily switch to the unlocked state and then switch back to the locked state). Similarly, if the lock mechanism 17 is already in the unlocked state when it receives an instruction to switch to the unlocked state from the lock control unit 23, it does not take any particular action in response to this instruction (it does not temporarily switch to the locked state and then switch back to the unlocked state).

[0047] The speed detection unit 24 detects (calculates) the moving speed of the user from the change in the distance between the user and the distance measurement sensors (5a, 5b) measured at regular time intervals by the distance measurement unit 14.

[0048] The control unit 11 of the automatic ticket gate 1 is composed of a hardware CPU, memory, and other electronic circuits. When the hardware CPU executes the passage control program according to the present invention, it operates as a passage determination unit 21, a door opening / closing control unit 22, a lock control unit 23, and a speed detection unit 24. The memory also has an area for expanding the passage control program according to the present invention and an area for temporarily storing data generated during execution of the passage control program. The memory also has storage areas for storing a first speed, a second speed, and a set distance, which will be described later. The control unit 11 may be an LSI that integrates the hardware CPU, memory, and the like. The hardware CPU is also a computer that executes the passage control method according to the present invention.

[0049] <3. Example of operation> FIG. 3 is a flowchart showing the ticket examination process of the automatic ticket gate in this example.

[0050] When a user enters a ticket gate passage, the automatic ticket gate 1 determines in the ticket processing unit 12 whether or not the ticket information has been read from the contactless IC card carried by the user (s1, s2). Whether or not the user has entered the ticket gate passage can be detected by a photoelectric sensor provided in the user detection unit 15. If the automatic ticket gate 1 has not read the ticket information from the contactless IC card carried by the user who has entered the ticket gate passage, it executes the processing from s7 onwards, which will be described later.

[0051] The ticket processing unit 12 may read the ticket information from the contactless IC card before the user enters the ticket gate passage, or may read the ticket information from the contactless IC card after the user enters the ticket gate passage. The timing at which the ticket processing unit 12 reads the ticket information from the contactless IC card is determined by the timing at which the user holds the contactless IC card over the antenna 3.

[0052] When the automatic ticket gate 1 reads ticket information from a contactless IC card carried by a user who has entered the ticket gate passage, it performs a passage determination process to determine whether or not to permit the user to pass through the ticket gate passage based on the read ticket information (s3). In s3, the passage determination unit 21 determines whether or not to permit the user to pass through the ticket gate passage based on the ticket information currently read from the contactless IC card. If the passage determination unit 21 determines that the user is permitted to pass through the ticket gate passage, it instructs the ticket processing unit 12 to write the ticket information related to the current ticket gate processing to the contactless IC card from which the ticket information was currently read. Once the passage determination unit 21 has completed writing the ticket information related to the current ticket gate processing to the contactless IC card from which the ticket information was currently read, it determines that the user is permitted to pass through the ticket gate passage. In other words, if the passage determination unit 21 fails to write the ticket information related to the current ticket gate processing to the contactless IC card from which the ticket information was currently read, it does not determine that the user is permitted to pass through the ticket gate passage.

[0053] The determination of whether or not a person can pass through based on ticket information is made based on factors such as the validity period, the validity section, whether or not there is a cycle error, and whether or not fare settlement is possible.

[0054] When the automatic ticket gate 1 determines that the user is permitted to pass through the ticket gate passage, the lock control unit 23 instructs the lock mechanism unit 17 to transition to an unlocked state (s4, s5). In addition, the door opening / closing control unit 22 instructs the door opening / closing mechanism unit 16 to open the door 2 (s6), and the process returns to s1.

[0055] Furthermore, when the automatic ticket gate 1 determines that the user is not permitted to pass through the ticket gate passage, the door opening / closing control unit 22 instructs the door opening / closing mechanism unit 16 to close the door 2 (s4, s7). Thereafter, the lock control unit 23 instructs the lock mechanism unit 17 to transition to a locked state (s8). Furthermore, the speed detection unit 24 detects (calculates) the moving speed of the user based on the change in the distance to the user over time measured by the distance measurement sensor 5 (s9). The moving speed of the user detected in s9 may be the speed immediately before the user enters the ticket gate passage, or may be the speed immediately after the user enters the ticket gate passage.

[0056] The lock control unit 23 determines whether the moving speed of the user calculated in s9 exceeds a predetermined first speed (s10). This first speed is, for example, the lower limit of the speed at which the user is predicted to be unable to stop in front of the closed door 2 and collide with it (this does not necessarily mean that the user will collide with it). This first speed is stored in a memory included in the control unit 11.

[0057] If the moving speed of the user calculated in s9 does not exceed the first speed, the lock control unit 23 returns to s1. If the moving speed of the user calculated in s9 exceeds the first speed, the lock control unit 23 instructs the lock mechanism unit 17 to transition to the unlocked state (s11), and returns to s1.

[0058] In this way, the automatic ticket gate 1 of this example switches the locking mechanism 17 to the unlocked state when there is a high possibility that a user entering the ticket gate passage will collide with the door 2 in the closed state, thereby softening the impact even if the user collides with the door 2 in the closed state. Furthermore, the automatic ticket gate 1 does not switch the door 2 to the open state even when the locking mechanism is switched to the unlocked state, so it is possible to make the user aware that the door 2 is in the closed state before the collision. As a result, the user decelerates in an attempt to stop in front of the door 2, thereby reducing the impact force applied by the user who collides with the door 2. Therefore, the automatic ticket gate 1 of this example can sufficiently prevent the door 2 from being deformed by an external force applied when it is in the closed state.

[0059] As mentioned above, the automatic ticket gate 1 in the above example is configured to accept contactless IC cards as tickets, but it may also be configured to accept magnetic tickets or optically readable tickets as tickets, or it may be configured to accept two or more types of tickets as tickets: contactless IC cards, magnetic tickets, and optically readable tickets.

[0060] Furthermore, the automatic ticket gate 1 may be configured to identify the user by face authentication, fingerprint authentication, or the like, and determine whether or not to permit the user to pass through the ticket gate passage.

[0061] <4. Modifications> Variation 1 The automatic ticket gate 1 of this modified example 1 has the configuration shown in Figures 1 and 2. Figure 4 is a flowchart showing the ticket gate processing of the automatic ticket gate of modified example 1. In Figure 4, the same steps as in Figure 3 are assigned the same step numbers.

[0062] The automatic ticket gate 1 of this modified example 1 executes the processes s1 to s7 in the same manner as in the above example.

[0063] In the automatic ticket gate 1 of this modified example 1, when the door opening / closing control unit 22 instructs the door opening / closing mechanism unit 16 to close the door 2 in s7, the speed detection unit 24 detects (calculates) the moving speed of the user based on the change in the distance to the user over time measured by the distance measurement sensor 5 (s21). The process in s21 is the same as the process in s9 in the example described above.

[0064] The lock control unit 23 determines whether the moving speed of the user calculated in s21 exceeds a predetermined first speed (s22). If the moving speed of the user calculated in s21 does not exceed the first speed, the lock control unit 23 instructs the lock mechanism unit 17 to transition to a locked state (s24) and returns to s1. On the other hand, if the moving speed of the user calculated in s21 exceeds the first speed, the lock control unit 23 instructs the lock mechanism unit 17 to transition to an unlocked state (s23) and returns to s1.

[0065] In this first modification, the frequency with which the locking mechanism 17 switches between the locked state and the unlocked state can be reduced, so that the life of the locking mechanism 17 can be extended.

[0066] Variation 2 The automatic ticket gate 1 of this modified example 2 also has the configuration shown in Figures 1 and 2. Figure 5 is a flowchart showing the ticket gate processing of the automatic ticket gate of modified example 2. In Figure 5, the same steps as in Figure 3 are assigned the same step numbers.

[0067] The automated ticket gate 1 of this modified example 2 executes the processes of s1 to s11 in the same manner as in the above example. In the automated ticket gate 1 of this modified example 2, when the lock control unit 23 instructs the lock mechanism unit 17 to transition to an unlocked state in s11, the door opening / closing control unit 22 determines whether the moving speed of the user calculated in s9 exceeds a predetermined second speed (s31). This second speed is faster than the first speed. Like the first speed, this second speed is also stored in the memory of the control unit 11.

[0068] If the moving speed of the user calculated in s9 does not exceed the second speed, the door opening / closing control unit 22 returns to s1. If the moving speed of the user calculated in s9 exceeds the second speed, the door opening / closing control unit 22 instructs the door opening / closing mechanism unit 16 to open the door 2 (s32), and returns to s1.

[0069] In this second modification, the frequency with which users collide with the door 2 in the closed state can be reduced, and therefore deformation of the door 2 can be further suppressed.

[0070] Variation 3 The automatic ticket gate 1 of this modified example 3 also has the configuration shown in Figures 1 and 2. Figure 6 is a flowchart showing the ticket gate processing of the automatic ticket gate of modified example 3. In Figure 6, the same steps as in Figure 5 are assigned the same step numbers.

[0071] In the automatic ticket gate 1 of this modification 3, if the door opening / closing control unit 22 determines in s31 that the moving speed of the user exceeds a predetermined second speed, it waits until the distance between the user and the closed door 2 reaches a set distance (s41), and then instructs the door opening / closing mechanism unit 16 to open the door 2 (s32). That is, the automatic ticket gate 1 of modification 3 differs from the automatic ticket gate 1 of modification 2 in that it performs the processing in s41. Similar to modification 2, modification 3 not only reduces the frequency with which users collide with the closed door 2, but also makes the user aware that the door 2 is closed.

[0072] Variation 4 In the above example, the moving speed of a user is detected from the change in the user's position measured by the distance measuring sensor 5, but the moving speed of a user may also be detected from the change in the user's position detected by, for example, multiple photoelectric sensors arranged along the passage direction of the ticket gate passage provided in the user detection unit 15. In this case, the distance measuring unit 14 including the distance measuring sensor 5 is not required, which simplifies the configuration of the automatic ticket gate 1.

[0073] Furthermore, since this can be achieved by simply modifying the control software of existing automatic ticket gates, the cost of building the system can be reduced.

[0074] Furthermore, the moving speed of the user may be detected using, for example, a millimeter wave radar, an ultrasonic sensor, an infrared sensor, or a TOF (Time Of Flight) camera, or may be detected by image processing.

[0075] In addition, in the above example, an automatic ticket gate 1 was described as being of a type (center flap type) in which the door 2 that closes when a user is not allowed to pass through the passage is located approximately in the center of the passage, but the door 2 may be located at each end of the passage, or may be located at one end.

[0076] Furthermore, in the above example, the present invention has been described as being applied to an automatic ticket gate installed at a station ticket gate, but the present invention can be applied to gate devices that are installed in various locations, such as entrances and exits of facilities (theme parks, office buildings, security areas, etc.), and that restrict the passage of users through passageways. In other words, the scope of application of the present invention is not limited to the automatic ticket gate 1 in the above example, but can be applied to all gate devices that are used in various locations and restrict the passage of users through passageways.

[0077] It should be noted that the present invention is not limited to the above-described embodiments, and that the components can be modified and embodied in practice without departing from the spirit of the invention. Furthermore, various inventions can be formed by appropriately combining multiple components disclosed in the above-described embodiments.
