Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a human detector for an automatic ticket gate, and more particularly, to a human detector for a automatic ticket gate comprising a reflection type sensor provided in a main body of the automatic ticket gate.

[0002]

2. Description of the Related Art In recent years, a human detector for an automatic ticket gate (hereinafter, referred to as a passenger) detecting a user (passenger) in a ticket gate passage of the automatic ticket gate.
"Human detector". ), A reflection type sensor has been used (Japanese Patent Application Laid-Open No. 10-11962).
No.).

As shown in FIG. 2, the reflection type sensor s detects a user A by receiving a light beam emitted from a light emitting element 10a and reflected by a user A by a light receiving element 10b. I am trying to do it. Therefore, by using this reflection type sensor s, it becomes possible to irradiate a light beam to a position where the height of the adult user can be detected and to selectively detect only the adult user, and to use the conventional sensor mounting bar. It has the feature of being able to detect adult users without the need.

[0004]

However, the human detector using the reflection type sensor is directed from a pair of housings constituting the main body of the automatic ticket gate to a space considered to be the height of an adult user, and The beam axis is fixedly illuminated on a vertical center line passing through the center of the ticket gate passage and further perpendicularly to the passage direction of the ticket gate passage. There is a drawback that erroneous detection occurs when there is disturbance light from the lamp.

FIG. 3 (a) is a front view of the automatic ticket gate body G viewed from the entrance side of the ticket gate passage P, and FIG. 3 (b) is the same figure (a). FIG. 2 is a side view taken along line AA of FIG.

[0006] Reflection type sensors S1 to S1 constituting a human detector
S3, S1 'to S3' are respectively provided at predetermined intervals in sensor mounting boxes 2, 2 'provided in a pair of housings 1, 1' constituting a main body G of the automatic ticket gate. I have. Here, the reflective sensors S1, S1 'are on the entrance side of the ticket gate P, the reflective sensors S2, S2' are substantially at the center of the ticket gate P, and the reflective sensors S3, S3 '.
Are provided on the exit (advance) side of the ticket gate passage P, respectively.

Since the reflection type sensors provided at the respective positions have the same configuration, the reflection type sensors S1, S1 'provided at the entrance side of the ticket gate P will be described as an example. The light beam axis indicated by the arrow ′ is a predetermined height of the ticket gate passage center line P ′ which is a vertical line passing through the center position of both the casings 1 and 1 ′ of the ticket gate P, that is, the height of the adult user. It is determined to intersect at a predetermined height H based on the height. When the ticket gate P is viewed from a plane, the ray axis is determined to be orthogonal to the passing direction P ″ of the ticket gate P. Therefore, the upper side where the two ray axes intersect detects the adult user. The adult detection area that can be obtained
(See hatching in (a)).

By the way, since the axes of the light beams respectively radiated from the two housings 1 and 1 'are fixedly provided, if there is disturbance light such as sunlight or lighting on the light axis,
There is a possibility that the reflection sensor may erroneously detect the disturbance light.

Accordingly, the present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide a human detector capable of preventing erroneous detection.

[0010]

SUMMARY OF THE INVENTION In order to achieve the above object, a human detector according to the present invention passes through a ticket gate passage from a housing constituting a main body of an automatic ticket gate provided with a ticket gate passage therebetween. A reflective sensor that irradiates light toward a predetermined height based on the height of the adult user who receives light, receives the light reflected by the user and receives the light reflected from the user, and detects the user. A human detector for a ticket gate,
The direction of the light beam emitted from the reflection sensor is provided so as to be adjustable in the horizontal direction when the ticket gate passage is viewed in a plane. Further, the reflection type sensor is characterized in that it is provided on each of a pair of housings constituting a main body of an automatic ticket gate provided so as to sandwich a ticket gate passage.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a main body G of an automatic ticket gate provided with a human detector according to one embodiment of the present invention. In particular, the directions of light axes of reflection sensors S1 to S3 and S1 'to S3' are shown. Is shown.

The reflection type sensors S1 to S3, S1 'to S3'
The main body G of the automatic ticket gate provided with is shown in FIG.
3B, the reflection type sensors S1 to S3 and S1 'to S3' are the same as those shown in FIGS.
As in (b), they are provided at predetermined intervals in the respective sensor mounting boxes 2 and 2 '. That is, the reflective sensors S1 and S1 'are at the entrance side of the ticket gate P, and the reflective sensors S2 and S2' are substantially at the center of the ticket gate P.
The reflection type sensors S3 and S3 'are exits (advance) of the ticket gate passage P.
Side.

Since the reflection type sensors provided at the respective positions have the same configuration, the reflection type sensors S1 and S1 'provided at the entrance side of the ticket gate P will be described as an example. S1 'includes a light emitting element and a light receiving element (FIG. 2)
), And each of the reflective sensors S1, S1 '
Are obtained so as to obtain the ray axis and ′ respectively. And, these ray axes, "
As shown in (a), when the ticket gate passage center line P 'intersects at a predetermined height H of an adult user and the ticket gate passage P is viewed from a plane, the passage direction P ″ of the ticket passage is It is provided so as to have a predetermined angle (hereinafter, referred to as a “horizontal angle”) θ1 with the orthogonal position.

The horizontal angle of the reflection sensors S2 and S2 'is θ2
In addition, the reflection sensors S3 and S3 'are provided such that the horizontal angle is θ3. That is, the reflection sensors S1 to S3, S1 'to S3 constituting the human detector of the present invention.
'Is configured so that the horizontal angle can be adjusted. Therefore, when there is disturbance light such as a sun ray or an illuminating light on the ray axes,,, ′ of the reflection type sensors S1 to S3, S1 'to S3', the disturbance light does not affect. Adjusted and set.

In the above example, the reflection sensors S1 to S1
S3 and S1 'to S3' are all provided with a horizontal angle, but if there is no disturbance light on the ray axis, the horizontal angle is set to 0 °, that is, perpendicular to the passing direction P ″ of the ticket gate passage. .

[0016]

The direction of the light beam emitted from the reflection type sensor in the human detector according to the present invention is provided so as to be adjustable in the horizontal direction when the ticket gate passage is viewed in a plane.
By adjusting the horizontal direction, erroneous detection can be effectively prevented. Further, when the reflection type sensor is provided on each of a pair of housings constituting the main body of the automatic ticket gate provided with the ticket gate interposed therebetween, human detection can be performed effectively.
