[0002]

BACKGROUND ART The structure of a conventional automatic gate shown in FIGS. 7-9. 7 is a top view, FIG. 8 is a side view in the XX direction in FIG. 9 , and FIG. 12 is a front view.

In the figure, 100a and 100b are automatic ticket gate units, respectively.
a and 100b constitute one automatic ticket gate. 101b is a unit on one side of another adjacent automatic ticket gate. The automatic ticket gate unit 100b has a ticket insertion slot 1, a ticket ejection slot 2, and traffic blocking doors 5b, 6
b is provided. In addition, the automatic ticket gate unit 100
Similarly, a is provided with a ticket insertion slot 3, a ticket discharge port 4, and a traffic blocking door 5a (not shown in the figure), 6a. These two automatic ticket gate units 100a, 100b
The space is used as a passage, and when passing in the left direction in the figure, the ticket insertion slot 1 and the ticket discharge slot 2 are used, and
a and 5b are used as doors for blocking traffic. When passing right in the figure, the ticket insertion slot 3 and the ticket discharge port 4 are used, and 6a and 6b are used as doors for blocking traffic.

Further, the automatic ticket gate units 100a and 100b shown in FIGS. 7 to 9 are provided with a plurality of sensors for detecting the traffic state of people and things. In the figure, reference numerals 10b to 19b denote light receivers of a transmission type photoelectric sensor, and light transmitters 10a to 19a (not shown) are provided in the automatic ticket gate unit 100a in opposition thereto. I have. Here, 10 and 16 are entrance detection sensors, 15 and 19 are exit detection sensors, 11 is an entrance-side entrance detection sensor, and 14 is an exit-side entrance detection sensor.
12, 13, 17 and 18 are used as sensors for detecting the center, respectively.

[0005] The sensors 10 to 15 are units 100a, 1
00b, the sensor 16
19 are provided on handrail-shaped frames 7a and 7b projecting upward from the unit body. This handrail-shaped frame 7a, 7
The height b is provided to detect the height of a person (thing) passing through the ticket gate. Specifically, one adult is counted by the operation of turning off all four photoelectric sensors 12, 13, 17, 18 in the center (detecting an object) and then turning off all, and only the photoelectric sensors 12, 13 are both turned on. ,
By turning off the object, the object is processed as an object such as a child or baggage, and the passing direction is determined based on the on / off timing of the other sensors and the four central sensors.

[0006]

However, in such a conventional automatic ticket gate, a handrail-shaped frame is provided because it is necessary to detect the height of an object passing through the passage. The frame-shaped body gives a feeling of psychological oppression to people passing by.

(2) There is a case where the handrail-shaped frame acts as an obstacle, and the baggage placed on the shoulder or the like hits when passing.

(3) Since the mounting height and shape of the handrail frame are constant, the shape and installation method of the automatic ticket gate body are limited.
There are also significant constraints on the design.

There have been problems such as the following.

SUMMARY OF THE INVENTION An object of the present invention is to solve such a conventional problem and to surely increase the height of an object (person, object) passing through a passage without using a conventional handrail-shaped frame. It is to provide an automatic ticket gate that can be detected.

[0011]

SUMMARY OF THE INVENTION The present invention relates to an automatic ticket gate having means for detecting that an object passing through a passage is at a predetermined height. The object detection sensor is provided on the far side and the upper side of the ticket reception unit in the direction of passage of the ticket reception unit of the automatic ticket gate body, and the height of the object passing through the passage is determined by the output value of the object detection sensor. It is characterized by detecting that it is at a predetermined height.

The automatic ticket gate main body is composed of two units sandwiching a passage, and each unit is provided with a reflection type object detection sensor pointing obliquely upward on the side of the passage.

In the automatic ticket gate according to the present invention, the object detection sensor detects an object by pointing diagonally upward on the side of the passage from a position at a fixed height on the side of the main body facing the passage. Since the height at which the object detection sensor is provided, the pointing direction, and the horizontal distance to the object detected by the object detection sensor are constant, an object having a constant height can be detected based on the detection result of the object detection sensor. Therefore, an object located diagonally above the automatic ticket gate main body can be detected, and the conventional handrail-shaped frame is unnecessary. In addition, since the object detection sensor is provided on the far side of the ticket reception unit of the automatic ticket gate main body and in the upper side of the ticket reception unit, it is possible to prevent the sensor axis of the object detection sensor from being blocked by a hand or the like. Can be prevented.

Further, since the object detection sensors are provided in each of the two units and are directed obliquely upward on the passage side,
Even if the passing object approaches one of the units, the detection is ensured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of an automatic ticket gate according to an embodiment of the present invention is shown in FIGS. 1 is a top view, FIG. 2 is a side view in the XX direction in FIG. 1, and FIG. 3 is a front view. In the figure, reference numerals 100a and 100b denote an automatic ticket gate unit main body (hereinafter, referred to as a unit main body), respectively. The two unit main bodies 100a and 100b form a pair and constitute one automatic ticket gate. Note that 101

As shown in FIG. 1 and FIG.
Projections 7 are formed on the upper surfaces of 00a and 100b, respectively, and four distance sensors 21 to 24 and 25 to 28 are provided on the side surfaces of the projections 7 on the passage side. Each of these distance sensors corresponds to the object detection sensor according to the present invention. For example, a distance-limited reflection type photoelectric sensor is used. In this method, a light beam irradiation unit and a light receiving unit such as a two-segment photodiode are integrated, and reflected light from a certain distance is detected by a triangulation method. Each distance sensor is directed obliquely upward on the side of the passage as shown in the figure, and detects the passage of an object (person) having a certain height or higher. Further, as is apparent from the figure, each distance sensor is located on the back side in the traveling direction with respect to the ticket insertion slot 1 for accepting the ticket of each unit main body 100a, 100b and above the ticket insertion slot 1. doing. Thereby, even when the user holds the ticket by hand and inserts it into the ticket insertion slot, the optical axis of the distance sensor is not hindered by the hand, and malfunction can be prevented. The distance sensors 21 and 25 detect the entrance together with the transmission sensor 10, the distance sensors 24 and 28 detect the exit together with the transmission sensor 15, and the distance sensors 22, 23,
Reference numerals 26 and 27 perform central detection together with the transmission type sensors 12 and 13.

Further, since each of the distance sensors is directed obliquely upward from the passage from the side surface of the protrusion 7 on the passage side, even if a part of an object passing through the adjacent passage is exposed above the protrusion 7. Therefore, the detection direction does not become a blind spot.

As shown in FIG. 3, if the minimum height of the object to be detected is H, the height of the distance sensor is h, and the interval is W,
The directional angle θ of each distance sensor is obtained by the following equation.

[0019] ^{θ = tan -1 2 (H-} h) / W Figure 4 is a block diagram of a control unit of the automatic ticket gate. CPU
Reference numeral 40 controls the control of the entire automatic ticket gate. The processing program of the CPU 40 is written in the ROM 41 in advance.
The RAM 42 is provided with an area for temporarily storing the ON / OFF state of each sensor and counting the number of passing persons. The transport mechanism 43 is a mechanism for transporting the inserted ticket along a predetermined route, and the transport control circuit 44 controls the transport. The magnetic head 46 reads or writes magnetic data recorded on the ticket being transported, and the read / write control circuit 47 controls data reading or writing. Reference numerals 5 and 6 denote passage blocking doors, and a door opening / closing control circuit 49 controls the opening / closing. The distance sensors 21 to 28 are sensors provided on the projection 7 on the upper surface of the unit main body as shown in FIG. 1, and the distance sensor control circuit 51 controls the distance detection of each distance sensor. Transmitter 10a, Receiver 10b
... The light transmitter 15a, the light receiver 15b, etc. are transmission photoelectric sensors as shown in FIG. 1, and the transmission sensor control circuit 53 controls the detection. The above control circuits are connected to bus lines via interface circuits 45, 48, 50, 52 and 54, respectively.

Next, the processing procedure of the automatic ticket gate control unit will be described with reference to the flowchart of FIG.

First, a transmission type photoelectric sensor 1 for detecting an entrance
0 and distance sensors 21 and 25, transmission type photoelectric sensors 15 and distance sensors 24 and 28 for detecting the exit, transmission type photoelectric sensors 11 for performing the entrance side entry detection, and transmission type photoelectric sensors 14 for performing the exit side entry detection. By detecting the state of the sensor, the state of approach and passage to the automatic ticket gate is confirmed. If there is an entry, the direction is stored (n1). Subsequently, transmission type photoelectric sensors 12 and 13 for performing center detection and center distance sensors 22 and 2 are provided.
After reading the states of 3, 26, and 27, if all of these sensors are turned on, then it is confirmed that all of these sensors are turned off, and the number of passers (adults) is counted up (n2 to n2). n6). If the transmission type photoelectric sensor 1
After only the switches 2 and 13 are turned on, the central distance sensors 22 and 2 are turned on.
3, 26, 27 are not turned on together, and the sensor 12,
When 13 is turned off, the passing object is regarded as a child or luggage, and the number of passing persons is not counted up (n7 → n1).

Next, two examples of an automatic ticket gate according to another embodiment are shown in FIGS.

The example shown in FIG. 6 shows the arrangement of the distance sensors 21 to 28 when each passage is constituted by one unit main body. Among these distance sensors 21 to 28,
The distance sensors 21 to 24 are connected to another adjacent unit body 10.
2b, and the distance sensors 25 to 28 are directed above the passage formed by the unit body 102a.

As shown in FIG. 1 to FIG. 3 and FIG. 6, by providing a pair of distance sensors pointing upwards of the passage, one of the passage passage locations (for example, approaching the automatic ticket gate unit 100b side). Variation in the detection height caused by the detection height variation or the variation in the case of passing close to the unit 100a).
In other words, even when the vehicle does not pass through the center of the passage and approaches the automatic ticket gate unit 100a or 100b, at least the distance sensor provided in the unit on the approach side detects an object (adult). Therefore, the height of the object can be reliably detected by taking the logical sum of the two outputs with each of the two facing distance sensors as a pair.

In the embodiment, a so-called distance-limited reflection-type photoelectric sensor is used as the object detection sensor. Alternatively, a general reflection-type photoelectric sensor for detecting the amount of reflected light can be used. Further, it is also possible to use a reflection-type sensor that uses a traveling wave such as a microwave or an ultrasonic wave and detects a distance based on a time difference until a reflected wave arrives from an object.

[0026]

According to the present invention, an object detection sensor is provided which is directed obliquely upward on the side of the passage, thereby detecting the height of an object passing through the passage. Therefore, the following effects can be obtained. Can be

(1) Since a handrail-shaped frame is not required, a passing person is not given a feeling of psychological oppression, and a smooth ticket gate can be performed.

(2) Obstacles are eliminated, so that relatively large luggage can pass over a shoulder or the like.

(3) The automatic ticket gate main body is not limited by the design due to the provision of the handrail-shaped frame, and the use form and the design flexibility are increased.
