b is provided with a plurality of sensors for detecting a traffic state of a person or an object. 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 in the figure) are provided in the automatic ticket gate unit 100a opposite thereto. I have. Here, 10 and 16 are entrance detection sensors, 15 and 19 are output detection sensors, 11 is entrance side entrance detection sensors, 14 is exit side entrance detection sensors, and 12, 13, 17 and 18 are center detection Used as sensors for

While the sensors 10 to 15 are provided on the main body side of the units 100a and 100b, the sensors 16 to 19 are provided on handrail-shaped frames 7a and 7b projecting upward from the unit main body. The handrail-shaped frames 7a and 7b are provided for detecting the height of a person (thing) passing through the ticket gate. Specifically, one adult is counted by the action of turning off all four photoelectric sensors 12, 13, 17, 18 in the center and then turning off all (detecting an object), and only the photoelectric sensors 12, 13 are turned on together. The object is processed as an object such as a dwarf or baggage by the operation of turning off, and the passing direction is determined by the on / off timing of the other sensors and the four central sensors.

(C) Problems to be solved by the invention However, in such a conventional automatic ticket gate,
Since the handrail-shaped frame is provided because it is necessary to detect the height of the object passing through the passage, (1) a person passing the handrail-shaped frame gives a feeling of psychological oppression.

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

(3) Since the mounting height and shape of the handrail-shaped frame are constant, the shape and installation method of the automatic ticket gate body are limited, and there are great restrictions on the design.

 There was such a problem.

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

(D) Means for Solving the Problems The present invention relates to an automatic ticket gate having means for detecting the height of an object passing through a passage, wherein an object detection sensor pointing obliquely upward on the side of the passage is provided. The height of an object passing through the passage is detected based on the output value of the sensor.

(E) Function 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 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, by providing the object detection sensor on the upper surface of the automatic ticket gate main body, an object located diagonally above the automatic ticket gate main body can be detected, and the conventional handrail-shaped frame is not required.

(F) Embodiment The structure of an automatic ticket gate according to an embodiment of the present invention is shown in FIG. (A) is a top view, and (B) is X in (A).
FIG. 4C is a side view in the −X direction, and FIG. In the figure
100a and 100b are automatic ticket gate units, respectively, and these two units 100a and 100b form a pair to constitute one automatic ticket gate. 101b is one unit of another adjacent automatic ticket gate. As in the conventional example shown in FIG. 6, the automatic ticket gate unit 100b is provided with a ticket insertion slot 1, a ticket discharge slot 2, and traffic blocking doors 5b and 6b. Similarly, the automatic ticket gate unit 100a 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. The automatic ticket gate unit 100b is provided with a plurality of photodetectors 10b to 15b of transmission type photoelectric sensors as shown in FIG. The automatic ticket gate unit 100a is provided with transmission-type photoelectric sensor transmitters 10a to 15a (not shown in the figure) opposed thereto. Here, the sensor 10 is used as an entrance detection sensor, 11 is used as an entrance side entrance detection sensor, 12, 13 are used as center detection sensors, 14 is used as an exit side entrance detection sensor, and 15 is used as an exit detection sensor.

As shown in FIG. 1 (A), the automatic ticket gate unit 100a
And two distance sensors 21 and 23 on the upper surface of 100b, respectively.
And 32, 34 are provided. 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 is detected within a certain distance 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.

The distance sensor 21 performs input detection together with the transmission type sensor 10, the distance sensor 34 performs exit detection together with the transmission type sensor 15, and the distance sensors 23 and 32 perform center detection together with the transmission type sensors 12 and 13.

As shown in FIG. 1 (C), assuming that 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 can be obtained by the following equation. .

θ = tan ⁻¹ {2 (H−h) / W} FIG. 2 is a block diagram of a control unit of the automatic ticket gate. CP
The U40 controls the entire automatic ticket gate. CPU4 is in ROM41
0 processing program has been written 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 includes a transport control circuit.
44 controls the transfer. The magnetic head 46 reads or writes magnetic data recorded on a ticket being conveyed, and a 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 34 are sensors provided on the upper surface of the automatic ticket gate unit as shown in FIG.
Performs distance detection control of each distance sensor. The light transmitter 10a, the light receiver 10b,..., The light transmitter 15a, the light receiver 15b, etc. are transmission type photoelectric sensors as shown in FIG.
Performs the detection control. 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, the transmission type photoelectric sensor 10 and the distance sensor 21 for detecting the entrance, the transmission type photoelectric sensor 15 and the distance sensor 34 for performing the exit detection, the transmission type photoelectric sensor 11 for performing the entrance side entry detection, and the transmission performing the exit side entry detection. Type photoelectric sensor 14
By detecting the state of each of the sensors, the state of approach and passage to the automatic ticket gate is confirmed. If there is an entry, the direction is stored (n1). Subsequently, the state of the transmission type photoelectric sensors 12 and 13 for performing the center detection and the states of the center distance sensors 23 and 32 are read, and if all four sensors are turned on, then all four sensors are turned off. After confirming that it is, count up the number of passers (adults) (n2 to n6). If only the transmission type photoelectric sensors 12 and 13 are turned on and then the central distance sensors 23 and 32 are not turned on and the sensors 12 and 13 are turned off, the passing object is regarded as a child or luggage. Do not count up the number of people passing by (n7 → n1).

Next, two examples of the automatic ticket gate according to the other embodiment will be described in the fourth.
This is shown in the figure and FIG.

The examples shown in FIGS. 4 and 5 use two distance sensors 21 and 31 as entrance detection sensors, use two distance sensors 24 and 34 as exit detection sensors, and use four distance detection sensors as center detection sensors. Distance sensors 22, 23, 32, and 33 are provided. As described above, both of the automatic ticket gate units 100a and 100b are provided with a pair of distance sensors that are directed obliquely upward on the side of the passage, so that a pair of distance sensors (e.g. Fluctuations in the detection height caused by such a situation as when the vehicle is approaching or passing close to the unit 100a). That is, without passing through the center of the passage, the automatic ticket gate unit 10
Even in the case of passing close to the 0a or 100b side, at least the distance sensor provided in the unit on the near side detects an object (adult). By taking the logical OR of, the height of the object can be reliably detected.

In particular, in the example shown in FIG. 5, the direction of each distance sensor is directed obliquely upward on the side of the passage and arranged so as to be oblique with respect to the traveling direction. As a result, it becomes difficult to intentionally escape from the detection range of the sensor, and a detection error in the height direction due to a piece that is lateral to the traveling direction is reduced.
In addition, since a detection component of the three-dimensional shape of the passing object (person) can be obtained, detection accuracy can be improved.

In the embodiment, a so-called distance-limited reflection type photoelectric sensor is used as the object detection sensor.
A general reflection-type photoelectric sensor that detects 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.

(G) Effect of the Invention According to the present invention, an object detection sensor whose detection direction is directed obliquely upward on the side of the passage is provided at a position at a constant height on the side of the passage, and thereby the height of the object passing through the passage is provided. Is detected, the following effects can be obtained.

(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 relatively large luggage can pass over a shoulder or the like.

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

(4) Since it is not necessary to mount and wire the sensor to the conventional handrail-shaped frame, workability at the time of installation is improved.

(5) Since the number of transmission type photoelectric sensors is reduced, assembling and installing an automatic ticket gate is facilitated, and costs can be reduced.
