By the way, when opening and closing the ticket gate doors 12, 12,
If, for example, the wheelchair user C is not in the opening / closing area α of the ticket gate door (see FIG. 2), there is no possibility that the ticket gate door 12 will hit the wheelchair user C or the wheelchair B. Allows ticket operation. On the other hand, if it is detected and confirmed that the wheelchair user C is in the opening / closing area α, the ticket gate door 12 is moved to the wheelchair user C or the wheelchair B.
In this case, the opening and closing operation of the ticket gate 12 is restricted (prohibited) in this case, and the ticket gate 12 is completely avoided from hitting the wheelchair user C or the wheelchair B.

As described above, the ticket gate door 12 and the wheelchair user C
The opening / closing control / restriction control of the ticket gate 12 is performed after confirming the positional relationship with the passenger, so that the opening / closing control can be constantly performed irrespective of the irregular traffic state of many passers-by. The user C can be protected, and a secure and reliable ticket gate operation can be obtained. Next, the opening control operation of the ticket gate of the automatic ticket gate will be described in detail with reference to the flowchart shown in FIG.

Now, as shown in FIG. 1 and FIG.
6, the wheelchair user C approaches from the right to the right, and the passer A approaches from the right to the left on the ticket gate passage 16, and the wheelchair user C is turned on by an automatic ticket gate (collection ticket gate). In the case of waiting for the passing of a passer A coming from the opposite direction in front of the left side of the dual-purpose machine), if the passer A enters with no bill or invalid ticket in the first step n1, the CPU 30 sets the ticket impossible data. , The alarm 45 is sounded to inform the driver that the vehicle is not suitable for traffic, and the guide display 15 is displayed and informed that the vehicle is not suitable for traffic. In the next second step n2, C
The PU 30 is connected to the ticket gates 12, 1 via the door opening / closing control circuit 40.
2 is closed as shown by the solid line in FIG. 2 to restrict the passage of invaders of billless / invalid tickets.

Next, in the third step n3, when the intruder of the above-mentioned billless / invalid ticket (see passer A) retreats from the ticket gate passage 16, originally in the fifth step n5, the ticket gate door 12 is opened.
Is opened, but since the wheelchair user C is approaching the automatic ticket gate, the CPU 30 executes a door traffic detection determination in the next fourth step n4.

That is, the CPU 30 is provided with the traffic detection sensor S
It is determined whether or not any one of S5, S6, S13, and S14 is turned ON (OR logic). When the wheelchair user C moves slightly to the right in the figure from the state shown in FIG. 1 and the traffic detection sensor S13 is turned on by his / her preceding foot, a YES determination is naturally made in the fourth step n4. That is, when the wheelchair user C enters the opening / closing area α shown in FIG.
In this fourth step n4, a YES determination is made.

Thus, YES in the above-described fourth step n4
If determined, the process moves to the next sixth step n6,
The CPU 30 prohibits the opening operation of the ticket gate 12 and keeps the ticket door 12 in a closed state. Therefore, even if the foot of the wheelchair user C approaches the lower part of the ticket gate 12, the opening operation of the ticket gate 12 is regulated. Because the movement is restricted, wheelchair user C
There is no concern that the user's feet or wheelchair B will be hit by the ticket gate 12, and the wheelchair user C can be protected, and safety and reliability can be ensured.

In the above-mentioned sixth step n6, an announcement to request the wheelchair user C to slightly retreat to the left in the drawing is executed by the notification means, and thereafter, the fourth step n4
If a routine that returns to the
Is quickly eliminated, which is extremely effective in practical use.

On the other hand, if NO is determined in the above-described fourth step n4 (for example, when the wheelchair user C is approaching the automatic ticket gate but has not entered the opening / closing area α), the following occurs. The process proceeds to the fifth step n5, in which the CPU 30 opens the ticket gate 12 via the door opening / closing control circuit 40. In this case, due to the operation of the control mechanism 18 shown in FIGS. The ticket gate door 12 opens at a high speed from the closed position to the halfway open position β, and the ticket gate door 12 opens slowly at a low speed from the halfway open position β to the fully open position, so that a wheelchair in a standby state is used in front of the automatic ticket gate. There is an effect that the operation of opening the ticket gate door 12 can be performed under the condition that the safety and the high reliability are secured without giving the person C any fear.

Next, a closing control operation of the ticket gate of the automatic ticket gate will be described in detail with reference to a flowchart shown in FIG. Now, according to FIGS. 3 and 4, a wheelchair user C as a passerby
Then, if a caregiver D or a general passer A as a passer-by enters the ticket gate passage 16 from the same direction, the passer-by (caregiver D or passer-A) in the first step n11. Is invaded with no bill or invalid ticket, CP
U30 sounds the alarm 45 by notifying the improper passage based on the ticket impossible data, and informs the guide display 15 of the improper passage by notifying the improper passage. 12 is closed (closed) to regulate the passage of an intruder (after-passer) of the billless / invalid ticket, but in this case, a wheelchair user C as a preceding passer comes first. Therefore, the process proceeds to the next second step n12, and in this second step n12, the CPU 30 executes the door portion traffic detection determination.

That is, the CPU 30 is provided with the traffic detection sensor S
It is determined whether or not any one of S5, S6, S13, and S14 is turned ON (OR logic). In other words, wheelchair user C
Enters the opening / closing area α, the sensor S14 is first turned on by the preceding foot, and thereafter, the above-described traffic detection sensors S5, S6 until the wheelchair user C completely passes through the opening / closing area α. , S13, and S14 are in the ON state. In such a case, the second
YES is determined in step n12. If YES is determined in the above-described second step n12, the next third step n1
The CPU 30 prohibits the closing operation of the ticket gate 12 and maintains the ticket door 12 in the open position in the third step n13.

Accordingly, the closing operation of the ticket gate 12 is restricted while the wheelchair user C is present in the above-mentioned opening / closing area α, so that the wheelchair user C or the wheelchair B passing through the opening / closing area α, for example, Ticket gate door 1 that closes behind
There is no concern that the wheelchair user 2 will be hit, and the wheelchair user C can be protected, and safety and reliability can be ensured.

On the other hand, the above-mentioned wheelchair user C is
Is completed in the second step n12, a NO determination is made in the second step n12.
14 and in this fourth step n14, the CPU 3
0 closes the ticket gate 12 via the door opening / closing control circuit 40. Next, the two-speed control operation (opening operation) of the ticket gate of this automatic ticket gate will be described in detail with reference to the flowchart shown in FIG.

In a first step n21, when the CPU 30 drives the motor 20 in the door opening direction in response to the command to open the ticket gate 12, the drive shaft 21 linked to the motor 20
Is driven in the door opening direction (clockwise direction in FIGS. 5 and 6), so that the ticket gate door 12 is sequentially opened from its fully closed position via the disk 23, the connecting pin 24, the link member 26, and the connecting pin 25. Driven at high speed.

As the drive shaft 21 rotates, the cam 22 integrally fitted to the coaxial shaft 21 also rotates in the same direction. Therefore, as shown by a solid line in FIG. (Corresponding to a position capable of passing through), the switch 27 is turned ON by the above-described cam 22 (see the second step n22).

Next, in a third step n23, the CPU 30 cuts off the power supply to the motor 20, and in the next fourth step n2
At 4, the CPU 30 executes the braking (braking) for applying the brake 19. The ticket gate 12 shown by a solid line in FIG.
In the range of the angle θ from the halfway open position β to the fully open position of the door shown by the solid line in FIG. 6, the above-mentioned ticket gate door 12 rotates at a low speed by the spring force of the return spring 28 (fifth embodiment).
Step n25).

That is, based on the opening command, the above-mentioned ticket gate door 12 is opened at a high speed by a motor drive from the fully closed position to the halfway open position β, and thereafter the return spring 28 is opened from the halfway open position β to the fully open position. Open at low speed due to spring force. Therefore, as shown in FIGS. 1 and 2, the wheelchair user C waiting in front of the automatic ticket gate
There is an effect that the door opening operation can be performed safely without causing any fear.

In short, detection means (passage detection sensor S13) for detecting the presence of an object (see passer A, user C of wheelchair B, caregiver D) in the open / close area α of the ticket gate 12
To S16) is provided below the above-mentioned ticket gate door 12, so that the detection means can be used, for example, for a wheelchair user C.
