Description

This invention relates to technology for restricting the passage of users through a passageway by opening and closing doors installed in the passageway.

Conventionally, gate devices have been used in various locations, such as station ticket gates and entrances/exits to 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.

For example, at station ticket gates, automatic ticket gates (gate devices) process tickets for passengers entering and exiting the station premises. As is well known, automatic ticket gates accept tickets held by passengers passing through the ticket gate passage and read the ticket information recorded on the ticket. Based on the ticket information read, the automatic ticket gates determine whether to permit the passenger to pass through the ticket gate passage, and depending on the result of the determination, open or close doors in the ticket gate passage to restrict the passenger's passage (see, for example, Patent Documents 1 and 2).

Recently, there are also automated ticket gates that use facial recognition, fingerprint recognition, etc. to identify users and determine whether or not to allow them through the ticket gate passage.

Japanese Patent Application Laid-Open No. 2006-85304 JP 2020-80109 A

As described in Patent Documents 1 and 2, a typical automatic ticket gate has doors on both sides of the width of the passage. The automatic ticket gate rotates these doors to switch between an open state, which allows users to pass through the passage, and a closed state, which does not allow users to pass through the passage.

As is well known, the closed state is when the doors on both sides of the width of the passageway are rotated so that their door faces face the direction of passageway in which users pass through the passageway. When installing or performing maintenance on an automated ticket gate, workers make adjustments to prevent users from noticing any discrepancies in the stopping positions of the doors when viewed from a distance in the closed state. Specifically, workers adjust the stopping position of the end of the door on the opposite side of the pivot axis on one side of the passageway in the direction of passageway in which users pass through the passageway, to align with the stopping position of the end of the door on the opposite side of the pivot axis on the other side of the passageway in the direction of passageway. This adjustment is a time-consuming task.

The object of this invention is to provide technology that makes it easy to adjust the stopping positions of doors located on both sides of the aisle width when in the closed state.

To achieve the above objectives, the gate device of this invention is configured as follows:

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

The system is equipped with doors that are rotatably installed on both sides of the width of the passageway through which users pass, and a door opening/closing unit that rotates the doors to switch between an open state in which the door surfaces on both sides of the passageway face each other, and a closed state in which the door surfaces on both sides of the passageway face the direction in which users pass through the passageway.

In addition, magnets are attached to the doors on both sides of the aisle width. The magnet attached to one door faces the magnet attached to the other door when the doors are closed.

For example, by attaching the magnet to the door at the end opposite the pivot axis that rotates the door using the door opening/closing unit, the magnets on the doors on both sides of the aisle width can be brought closer together when the door is closed.

Also, for example, if a magnet attached to one door and a magnet attached to the other door are placed facing each other with opposite polarities, a magnetic force can be generated that attracts the two doors together when they are closed.

The magnets may also be attached in two locations, at the top and bottom ends of the door, or in the center of the door's height, or at the top, bottom, and center, or elsewhere.

The magnet may be a permanent magnet or an electromagnet.

Furthermore, the gate device may have a door located in the middle of the passageway between the entrance and exit for users, on the exit side for users, or at both the entrance and exit for users.

This invention makes it easy to adjust the stopping positions of the doors on both sides of the aisle width when they are closed.

The following describes an embodiment of this invention.

<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 in the direction A shown in FIG. 1. Also, FIG. 2(A) is a plan view showing the door in a closed state, and FIG. 2(B) is a view taken along the arrows A-A shown in FIG. 2(A). 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.

Automated ticket gate 1 reads the ticket information on the ticket presented by the user and determines whether to allow 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 publicly known, so a description of them will be omitted here.

In this example, for simplicity, the automatic ticket gate 1 will be described as being configured to accept contactless IC cards as tickets. However, the automatic ticket gate 1 may also be configured to accept magnetic tickets or optically readable tickets as tickets, or may be configured to accept two or more of contactless IC cards, magnetic tickets, and optically readable tickets as tickets.

In this example, the automatic ticket gate 1 has antennas 3 (3a, 3b) on both sides of the ticket gate passage. The 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 Figure 1, a user entering the station holds their contactless IC card over antenna 3a, and a user leaving the station holds their contactless IC card over antenna 3b.

Note that if users only move in one direction through the ticket gate passage, one of the antennas 3 (3a or 3b) does not need to be installed.

The automatic ticket gate 1 determines whether to allow the user to pass through the ticket gate passage based on the ticket information read from the contactless IC card that the user holds over the antenna 3.

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) that are pivotally attached to both sides of the width of the ticket gate passage. 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 door 2 in a closed state (closed state).

When in the open state, the door surfaces of doors 2a and 2b face each other across the ticket gate passage (not shown). When in the closed state, the door surfaces of doors 2a and 2b face each other in the direction of user passage through the ticket gate passage. The automatic ticket gate 1 switches between the open and closed states by rotating the doors 2 approximately 90 degrees. The rotation axis 10a of door 2a is on the left side in Figure 2 (A), and the rotation axis 10b of door 2b is on the right side in Figure 2 (B). The rotation axis 10a is located in the housing on the right side shown in Figure 1, and the rotation axis 10b is located in the housing on the left side shown in Figure 1.

As shown in Figures 1 and 2(A), when door 2 is closed, the end of door 2a opposite pivot axis 10a and the end of door 2b opposite pivot axis 10b face each other at approximately the center of the width of the ticket gate passage. As shown in Figure 2, at the end of door 2a opposite pivot axis 10a, magnet 5a is attached to the upper end of door 2a and magnet 6a is attached to the lower end of door 2a. Similarly, at the end of door 2b opposite pivot axis 10b, magnet 5b is attached to the upper end of door 2b and magnet 6b is attached to the lower end of door 2a. Magnets 5a and 5b are attached at opposing heights when door 2 is closed. Similarly, magnets 6a and 6b are attached at opposing heights when door 2 is closed. Magnets 5a, 5b, 6a, and 6b are permanent magnets.

In addition, when in the closed state, the polarity of the surface of magnet 5a facing magnet 5b is different from the polarity of the surface of magnet 5b facing magnet 5a. For example, the surface of magnet 5a facing magnet 5b is a north pole, and the surface of magnet 5b facing magnet 5a is a south pole. Similarly, when in the closed state, the polarity of the surface of magnet 6a facing magnet 6b is different from the polarity of the surface of magnet 6b facing magnet 6a. For example, the surface of magnet 6a facing magnet 6b is a north pole, and the surface of magnet 6b facing magnet 6a is a south pole.

In this example, when doors 2a and 2b are rotated to transition from an open state to a closed state, magnet 5a attached to door 2a and magnet 5b attached to door 2b come close to each other and face each other at approximately the center of the width of the ticket gate passage, and magnet 6a attached to door 2a and magnet 6b attached to door 2b come close to each other and face each other at approximately the center of the width of the ticket gate passage. This generates an attractive magnetic force between magnet 5a and magnet 5b, and an attractive magnetic force between magnet 6a and magnet 6b. The end of door 2a on the opposite side of rotation axis 10a and the end of door 2b on the opposite side of rotation axis 10b stop in approximately the same position in the direction of user passage through the ticket gate passage due to the magnetic forces generated between magnets 5a and 5b and between magnets 6a and 6b.

Therefore, in this example of the automatic ticket gate 1, the stopping positions of the doors 2a and 2b located on both sides of the width of the ticket gate passage can be easily adjusted when the gate is closed during installation or maintenance.

<2. Configuration example>
3 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 user detection unit 14, a door opening/closing mechanism unit 15, and a communication unit 16.

The control unit 11 controls the operation of each part of the automatic ticket gate 1. The control unit 11 also has a passage determination unit 21 and a door opening/closing control unit 22. The passage determination unit 21 and door opening/closing control unit 22 of the control unit 11 will be described later.

The ticket processing unit 12 has antennas 3 (3a, 3b) and uses wireless communication with a contactless IC card held over the antenna 3 to read ticket information recorded on the contactless IC card and write ticket information to the contactless IC card.

The display unit 13 has a display (not shown) and displays guidance information for the user on the display in accordance with instructions from the control unit 11.

The user detection unit 14 has multiple 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 from the detection output of each photoelectric sensor. The photoelectric sensors may be reflective or transmissive (a type in which a light-emitting element and a light-receiving element are arranged opposite each other across the ticket gate passage).

The door opening/closing mechanism 15 opens and closes the doors 2a and 2b installed in the ticket gate passageway in accordance with instructions from the control unit 11.

The communication unit 16 communicates with a higher-level device such as a station server. The communication unit 16 may be configured to communicate with the higher-level device wirelessly or via a wired connection.

Next, we will explain the passage determination unit 21 and door opening/closing control unit 22 that the control unit 11 has.

Based on the ticket information read from the contactless IC card by the ticket processing unit 12, the passage determination unit 21 determines whether a user who holds this contactless IC card over antenna 3 (3a, 3b) is permitted to pass through the ticket gate. 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 for 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 for the current ticket gate processing to the contactless IC card from which the ticket information was read, it allows the user to pass through the ticket gate. In other words, if the passage determination unit 21 fails to write the ticket information for the current ticket gate processing to the contactless IC card from which the ticket information was read (if a write error occurs), it will not allow the user to pass through the ticket gate.

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 15 to open the door 2. Furthermore, 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 15 to close the door 2.

Note that if door 2 is already in an open state when door opening/closing mechanism 15 receives an instruction to open door 2 from door opening/closing control unit 22, it will not open or close door 2 (it will close door 2 once and not open it again). Similarly, if door 2 is already in a closed state when door opening/closing mechanism 15 receives an instruction to close door 2 from door opening/closing control unit 22, it will not open or close door 2 (it will open door 2 once and not close it again).

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 ticket gate processing program, it operates as a passage determination unit 21 and a door opening/closing control unit 22. The memory also has an area for expanding the ticket gate processing program and an area for temporarily storing data generated when the ticket gate processing program is executed. The control unit 11 may be an LSI that integrates the hardware CPU, memory, etc. The hardware CPU is also a computer that executes the passage control method of this invention.

<3. Operation example>
FIG. 3 is a flowchart showing the ticket examination process of the automatic ticket gate in this example.

When a user enters the 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). Detection of whether or not the user has entered the ticket gate passage can be performed by a photoelectric sensor in the user detection unit 14. 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.

The ticket processing unit 12 may read the ticket information from the contactless IC card before the user enters the ticket gate, or may read the ticket information from the contactless IC card after the user has entered the ticket gate. 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.

When the automatic ticket gate 1 reads ticket information from the 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 passage 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 passage through the ticket gate passage is permitted, 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.

Determination of whether or not a route can be passed is based on ticket information, including the validity period, valid section, whether or not there is a cycle error, and whether or not fare settlement is possible.

If the automatic ticket gate 1 determines that the user should be allowed to pass through the ticket gate passage, the door opening/closing control unit 22 instructs the door opening/closing mechanism unit 15 to open the door 2 (s5), and the process returns to s1.

Furthermore, if 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 15 to close the door 2 (s4) and the process returns to s1.

In this example, as described above, when doors 2a and 2b are rotated from the open state to the closed state, the magnet 5a attached to door 2a and the magnet 5b attached to door 2b come close to each other and face each other at approximately the center of the width of the ticket gate passage, and the magnet 6a attached to door 2a and the magnet 6b attached to door 2b come close to each other and face each other at approximately the center of the width of the ticket gate passage. This generates an attractive magnetic force between magnets 5a and 5b, and also between magnets 6a and 6b. The end of door 2a on the opposite side of rotation axis 10a and the end of door 2b on the opposite side of rotation axis 10b stop in approximately the same position in the direction of user passage through the ticket gate passage due to the magnetic forces generated between magnets 5a and 5b and between magnets 6a and 6b.

Therefore, in this example of the automatic ticket gate 1, the stopping positions of the doors 2a and 2b located on both sides of the width of the ticket gate passage can be easily adjusted when the gate is closed during installation or maintenance.

4. Modifications
Modification 1
In this modified example 1, the door surfaces of doors 2Aa and 2Ab are rectangular, as shown in Fig. 5. Fig. 5(A) is a plan view showing the doors in a closed state, and Fig. 5(B) is a view seen from the direction of the arrows A-A shown in Fig. 5(A). The automatic ticket gate 1 of this modified example 1 has the same configuration as shown in Fig. 3, although the outer shapes of doors 2Aa and 2Ab are different.

In addition, in this variant 1, as shown in FIG. 5, magnet 5Aa is attached to the end of door 2Aa opposite the pivot axis, and magnet 5Ab is attached to the end of door 2Ab opposite the pivot axis. Magnets 5Aa and 5Ab are attached approximately at the center in the height direction of doors 2Aa and 2Ab. Furthermore, magnets 5Aa and 5Ab are attached so that they are close to each other and face each other when in the closed state.

In the automated ticket gate 1 of this variant 1, as in the example described above, when doors 2Aa and 2Ab are rotated from the open state to the closed state, the magnet 5Aa attached to door 2Aa and the magnet 5Ab attached to door 2Ab come close to each other and face each other at approximately the center of the width of the ticket gate passage. This generates a magnetic force that attracts magnets 5Aa and 5Ab. The magnetic force generated between magnets 5Aa and 5Ab causes the end of door 2Aa on the opposite side of rotation axis 10a and the end of door 2Ab on the opposite side of rotation axis 10b to stop in approximately the same position in the direction of user passage through the ticket gate passage.

Therefore, even with this automated ticket gate 1 of variant 1, the stopping positions of the doors 2Aa and 2Ab located on both sides of the width of the ticket gate passage can be easily adjusted when in the closed state during installation or maintenance.

Modification 2
In this modified example 2, as shown in Fig. 6, the door surfaces of doors 2Ba and 2Bb are rectangular, similar to modified example 1. Fig. 6(A) is a plan view showing the doors in a closed state, and Fig. 6(B) is a view seen from the arrow A-A direction shown in Fig. 6(A). The automatic ticket gate 1 of this modified example 2 has the configuration shown in Fig. 3.

In addition, in this variant 2, as shown in FIG. 5, magnets 5Ba and 6Ba are attached to the end of door 2Ba opposite the pivot axis, and magnets 5Bb and 6Bb are attached to the end of door 2Bb opposite the pivot axis. Magnets 5Ba and 5Bb are attached to the upper edges of doors 2Ba and 2Bb in the height direction. Magnets 6Ba and 6Bb are attached to the lower edges of doors 2Ba and 2Bb in the height direction. Magnets 5Ba and 5Bb are attached so that they are close to each other and face each other when in the closed state. Similarly, magnets 6Ba and 6Bb are attached so that they are close to each other and face each other when in the closed state.

In this automated ticket gate 1 of variant 2, when doors 2Ba and 2Bb are rotated from the open state to the closed state, the magnet 5Ba attached to door 2Ba and the magnet 5Bb attached to door 2Bb come close to each other and face each other at approximately the center of the width of the ticket gate passage, and the magnet 6Ba attached to door 2Ba and the magnet 6Bb attached to door 2Bb come close to each other and face each other at approximately the center of the width of the ticket gate passage. This generates an attractive magnetic force between magnet 5Ba and magnet 5Bb, and also generates an attractive magnetic force between magnet 6Ba and magnet 6Bb. The end of door 2Ba on the opposite side of rotation axis 10a and the end of door 2Bb on the opposite side of rotation axis 10b stop in approximately the same position in the direction of user passage through the ticket gate passage due to the magnetic forces generated between magnet 5Ba and magnet 5Bb, and between magnet 6Ba and magnet 6Bb.

Therefore, even with this automated ticket gate 1 of variant 2, the stopping positions of the doors 2Aa and 2Bb located on both sides of the width of the ticket gate passage can be easily adjusted when in the closed state during installation or maintenance.

Note that the number of magnets attached to the door and the positions at which they are attached are not limited to the examples shown in Figures 2, 5, and 6 above. In other words, the number of magnets attached to the door and the positions at which they are attached shown in Figures 2, 5, and 6 above are merely examples.

Modification 3
In the above example, the magnets 5a, 5b, 6a, and 6b attached to the door are permanent magnets, but they may also be electromagnets. Even if electromagnets are used, their attachment positions are, for example, the positions shown in Figure 2. Even if the magnets 5a, 5b, 6a, and 6b are electromagnets, their opposing polarities are different when the door is in the closed state.

The automated ticket gate 1 of this variant 3 has the configuration shown in Figure 3, but differs in that the door opening/closing mechanism 15 turns on/off the electromagnets 5a, 5b, 6a, and 6b in accordance with instructions from the door opening/closing control unit 22.

Furthermore, the automated ticket gate 1 of this modified example executes the process shown in Figure 7. In Figure 7, the same steps as in Figure 4 are assigned the same step numbers, and their explanations will be omitted.

The automated ticket gate 1 of Variation 3 executes the processes described above in steps s1 to s4. When the automated ticket gate 1 of Variation 3 determines in step s4 that passage is permitted, the door opening/closing control unit 22 instructs the door opening/closing mechanism unit 15 to turn off the electromagnets 5a, 5b, 6a, and 6b (s11). Then, in step s5, the door opening/closing control unit 22 instructs the door opening/closing mechanism unit 15 to open door 2, and the process returns to step s1.

Furthermore, when the automatic ticket gate 1 of Variation 3 determines in s4 that passage is not permitted, in the same manner as in the above example, in s6, the door opening/closing control unit 22 instructs the door opening/closing mechanism unit 15 to close the door 2. Thereafter, the door opening/closing control unit 22 instructs the door opening/closing mechanism unit 15 to turn on the magnets 5a, 5b, 6a, and 6b, which are electromagnets (s12), and the process returns to s1.

In this variation 3, when doors 2a and 2b are closed, magnets 5a, 5b, 6a, and 6b, which are electromagnets attached to doors 2a and 2b, are turned on, generating an attractive magnetic force between magnets 5a and 5b, and an attractive magnetic force between magnets 6a and 6b. The magnetic forces generated between magnets 5a and 5b, and between magnets 6a and 6b, cause the end of door 2a on the opposite side of pivot shaft 10a and the end of door 2b on the opposite side of pivot shaft 10b to stop in approximately the same position in the direction of user passage through the ticket gate.

Therefore, even with this automated ticket gate 1 of variant 3, the stopping positions of the doors 2a and 2b located on both sides of the width of the ticket gate passage can be easily adjusted when in the closed state during installation or maintenance.

The electromagnets on doors 2a and 2b may be mounted at the positions shown in Figure 5 or Figure 6.

In addition, in the above example, an automatic ticket gate 1 was described as being of the type (center flap type) in which the doors 2a and 2b that close when a user is not allowed to pass through the passage are located approximately in the center of the passage, but the doors 2 may be located at both ends of the passage, or at one end.

In addition, while the above example describes the application of the present invention to an automatic ticket gate installed at a station ticket gate, the present invention can be applied to gate devices installed in various locations, such as entrances and exits of facilities (theme parks, office buildings, security areas, etc.), 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 used in various locations that restrict the passage of users through passageways.

Note that this invention is not limited to the above-described embodiment, and the components can be modified and embodied in practice without departing from the spirit of the invention. Furthermore, various inventions can be created by appropriately combining multiple components disclosed in the above-described embodiment. For example, some components may be omitted from all of the components shown in the embodiment. Furthermore, components from different embodiments may be combined as appropriate.
