Description

  The present invention relates to a light-emitting guidance sign for moving a vehicle to a stop position for a driver when an automobile is parked in a parking space.

  In parking lots at various locations, such as multi-level parking lots, department store and supermarket parking lots, convenience store parking lots, and amusement facility parking lots, signs are installed to guide the vehicle to a predetermined stop position. ing. Such signs are known to be light-emitting and bendable when the vehicle collides, and can be restored to its original state without being damaged when the vehicle leaves (for example, patents). References 1 and 2).

  In such a light-emitting induction sign, a solar cell, a substrate unit, a power storage device, and the like are incorporated in the sign main body, and a light emitting unit is provided for each sign. Thereby, there is an advantage that it is easy to see from the driver as compared with a sign that is not light emitting type.

  However, in the case of the light emitting guidance sign according to the conventional example, lighting or blinking of the light emitting unit is merely made more conspicuous than a light emitting type sign. Therefore, even if the driver uses the light-emitting guidance sign according to the conventional example as a guide for the stop position, the stop position cannot be reliably recognized by the sign.

  Patent Document 3 discloses a portable light-emitting guidance sign (parking guidance device) that is portable. The sign disclosed in this document is provided with two types of vehicle body detection sensors having different detection directions, and the two types of vehicle body detection sensors can detect that the vehicle has entered the parking space. In addition, it is possible to detect that the vehicle has reached the stop position. The vehicle is guided by selectively using a light that is turned on when the vehicle enters the parking space and a light that is turned on when the vehicle reaches the stop position.

However, in the case of this sign, since the sign is placed in one corner of the parking space and the vehicle has reached the position where it crosses the sign, it is recognized that the vehicle has reached the stop position. It must be installed outside the horizontal width. Therefore, it cannot be installed unless there is a margin in the lateral width direction of the parking space. Therefore, it is often impossible in practice to use such a sign in a place where parking of a large number of vehicles is required, such as the above-described three-dimensional parking lot and parking lots of various facilities. Moreover, since this sign is installed outside the lateral width of the vehicle, it cannot be guided in the width direction of the vehicle. Furthermore, there is no function to stop the vehicle when the vehicle exceeds the stop position.
Japanese Patent No. 2555855 Japanese Patent No. 2975561 Japanese Patent Laid-Open No. 11-53933

  As described above, in the case of the light-emitting guidance sign according to the conventional example, the guidance of the vehicle to the stop position in the parking space is still insufficient, and there is room for improvement.

  An object of the present invention is to provide a light-emitting guidance sign that improves the accuracy of vehicle guidance.

  The present invention employs the following means in order to solve the above problems.

That is, the luminescent induction label of the present invention is
In the light-emitting guidance sign that is installed at the back and center of the parking space and moves the vehicle to the stop position for the driver,
Detecting means for sensing the vehicle and detecting the distance between the guidance sign body and the vehicle when the vehicle enters the parking space;
A light emitting means that is provided at a height that is visually recognized by the driver, and that emits light in response to vehicle sensing by the detection means;
Control means for changing the color of the light emitted by the light emitting means stepwise according to the distance between the guidance sign body detected by the detecting means and the vehicle.

  According to the present invention, since the color of the light emitted by the light emitting means changes stepwise according to the distance between the guidance sign body and the vehicle, the driver can sense the distance between the vehicle and the guidance sign body. Easy to grab. Therefore, the vehicle can be moved to a predetermined stop position more reliably. Moreover, since the guidance sign is installed in the back and center of the parking space, it can be used even if there is no margin in the width of the parking space. Further, since the guidance sign is in the center of the parking space, there is a guidance effect on the lateral width of the vehicle. Furthermore, even if the vehicle has exceeded the stop position, the vehicle collides with the guide sign, so that the guide sign itself exerts a function of suppressing overrun of the vehicle.

  The control means changes the color of light emitted by the light emitting means from blue or green to yellow as the distance between the guidance sign main body detected by the detecting means and the vehicle becomes shorter, and the vehicle is stopped. If you come up to it, you should make it red.

  That is, a signal is generally associated with the color of light changing from blue or green to yellow and from yellow to red. Then, “progress permission” is associated with blue or green, “caution” is associated with yellow, and “cannot proceed (stop)” is associated with red. As a result, the color of the light emitted from the light emitting means provided on the guidance sign changes from blue or green to yellow, so that the driver can easily guess that the vehicle is approaching the stop position. The driver can easily guess that the vehicle has reached the stop position by changing the color of the light from yellow to red. Therefore, even if the driver has no knowledge about the light-emitting guidance sign according to the present invention, the vehicle can be accurately stopped at the stop position by the guidance sign.

  The control unit may turn off the light emitting unit when the detection unit continuously detects a state where the vehicle is at a stop position for a certain period of time.

  Thus, after the vehicle stops, useless power consumption can be suppressed by turning off the light emitting means.

Sound generation means for generating sound in response to vehicle detection by the detection means;
The control means may change the color of light emitted by the light emitting means in a stepwise manner and also change the sound to be generated in a stepwise manner.

  Thus, by changing not only the color of light but also the generated sound, the vehicle can be moved more effectively to the stop position with respect to the driver.

Further, the luminescent induction label of the present invention is
In the light-emitting guidance sign that is installed at the back and center of the parking space and moves the vehicle to the stop position for the driver,
Detecting means for sensing the vehicle and detecting the distance between the guidance sign body and the vehicle when the vehicle enters the parking space;
A light emitting means that is provided at a height that is visually recognized by the driver, and that emits light in response to vehicle sensing by the detection means;
Control means for changing the blinking interval by the light emitting means stepwise according to the distance between the guidance sign main body and the vehicle detected by the detecting means.

  According to the present invention, since the blinking interval by the light emitting means changes stepwise according to the distance between the guidance sign body and the vehicle, the driver can easily grasp the sense of distance between the vehicle and the guidance sign body. Therefore, the vehicle can be moved to a predetermined stop position more reliably. Moreover, since the guidance sign is installed in the back and center of the parking space, it can be used even if there is no margin in the width of the parking space. Further, since the guidance sign is in the center of the parking space, there is a guidance effect on the lateral width of the vehicle. Furthermore, even if the vehicle has exceeded the stop position, the vehicle collides with the guide sign, so that the guide sign itself exerts a function of suppressing overrun of the vehicle.

  As the distance between the guidance sign main body detected by the detection means and the vehicle becomes shorter, the control means shortens the blinking interval by the light emitting means stepwise, and remains on when the vehicle reaches the stop position. It is good to make it.

  As described above, the flashing interval of the light emitting means is shortened, so that the driver can easily estimate that the vehicle is approaching to the vicinity of the stop position. By changing from blinking to lighting, the driver can easily guess that the vehicle has reached the stop position. Therefore, even if the driver has no knowledge about the light-emitting guidance sign according to the present invention, the vehicle can be accurately stopped at the stop position by the guidance sign.

  The control unit may turn off the light emitting unit when the detection unit continuously detects a state where the vehicle is at a stop position for a certain period of time.

  Thus, after the vehicle stops, useless power consumption can be suppressed by turning off the light emitting means.

Sound generation means for generating sound in response to vehicle detection by the detection means;
The control means may change the color of light emitted by the light emitting means in a stepwise manner and also change the sound to be generated in a stepwise manner.

  Thus, by changing not only the color of light but also the generated sound, the vehicle can be moved more effectively to the stop position with respect to the driver.

  The guide sign body may be configured to bend when receiving an external force and to be restored to its original state when the external force disappears.

  Thereby, even if a vehicle body collides with a guidance sign main body, damage to a guidance sign main body can be suppressed.

  The detection means may be a sensor provided on the guidance sign body.

  It is also preferable that the detection means is a mat-shaped sensor provided in a portion on which the vehicle is placed, separately from the guidance sign body.

On the optical path of the light emitted by the light emitting means, a lens for improving visibility is provided,
The lens may be satin-finished at least partially.

  Thereby, the bad influence by the light from the outside can be reduced.

  A plurality of concave and convex portions are provided on the surface of the lens so that the optical path is a concave portion, and it is preferable that the concave portion is subjected to a satin treatment.

  By doing so, even if the vehicle comes into contact with the lens, the recesses are hardly damaged, so that the function can be prevented from being impaired.

The light emitting means includes an LED and a cover for protecting the LED,
The distance from the tip of the LED to the cover may be set to be equal to or larger than the diameter of the LED.

  Thereby, the bad influence by the light from the outside can be reduced.

  The guide sign body may be provided with reflecting means for reflecting light in a region including the back side where the light emitting means is provided.

  Thereby, the position of the guidance sign main body can be recognized at night, even if the light emitting means does not emit light.

  In addition, said each structure can be employ | adopted combining as much as possible.

  As described above, according to the present invention, it is possible to improve the accuracy of vehicle guidance.

  The best mode for carrying out the present invention will be exemplarily described in detail below with reference to the drawings. However, the dimensions, materials, shapes, relative arrangements, and the like of the components described in this embodiment are not intended to limit the scope of the present invention only to those unless otherwise specified. .

FIG. 6 is a schematic diagram illustrating a state where the vehicle is guided by the light-emitting guidance sign according to the first embodiment of the present invention. FIG. 7 is a schematic view showing a parking lot seen from above.

<Whole light-emitting guidance sign>
In particular, with reference to FIG. 1 to FIG. 3, the configuration of the luminescent induction sign according to Example 1 of the present invention will be described. The light emitting guidance sign 100 according to the present embodiment includes a guidance sign body 10, a light emitting unit 20 provided at a height visually recognized by a driver, a vehicle detection sensor 30 that senses that a vehicle has entered a parking space, and The distance sensing sensor 40 that detects the distance between the guidance sign body 10 and the vehicle, and the control unit 50 that controls the driving of the light emitting unit 20 are provided.

<Induction sign body>
The guide sign main body 10 includes a cylindrical outer skin 11 constituting an appearance, a foam 12 housed inside the outer skin 11, a fixing base 13 for fixing the light emitting guide sign 100 at a desired position, An anchor 14 embedded in the ground, a bolt 15 for fixing the fixing base 13 to the anchor 14, a cap 16 that closes the upper portion of the outer skin 11, and a reinforcing body 17 that supports the guide sign body 10 are provided. Yes.

  In addition, when the vehicle collides with the light-emitting guide sign 100, the guide sign body 10 itself bends, and when the vehicle leaves, this embodiment is performed so that the guide sign body 10 is restored to the original state. The guide sign main body 10 according to the example has elasticity. This also prevents the light emitting guidance sign 100 and the vehicle from being damaged even if the vehicle collides with the light emitting guidance sign 100.

  Specifically, the guide sign main body 10 has elasticity by devising the material of the outer skin 11 and the material of the foam 12. For example, a resin material having elasticity can be used as the material of these members. As a more specific example, a material made of polyurethane and ABS (mixing ratio 55:45) can be used as the material of the outer skin 11. As for the physical properties when this material is used, for example, the representative value when the tensile strength is measured by the test method of JIS K7311 is 34.3 MPa, and the representative value when the elongation is measured by the test method of JIS K7311 is 650. The representative value when the hardness (Shore D) is measured by the test method of JIS K7215 is D54. Moreover, as a material of the foam 12, semi-rigid foamed polyurethane can be used. The physical properties when this material is used are, for example, a representative value of 0.1328 / cm when the density is measured by the test method of JIS K6301, and the hardness (Asker C) is measured by the test method of JIS K6301. The representative value at this time is C41.

  Thus, by devising the material of the outer skin 11 and the material of the foam 12, the guide sign body 10 has elasticity by the foam 12 while having desired rigidity by the outer skin 11 and the reinforcing body 17. Thereby, the light-emitting guidance sign 100 can be kept upright when no external force is applied, and can be restored to the original upright state even if the vehicle collides and bends. Moreover, even if the vehicle collides, it is possible to prevent the light emitting guidance sign 100 and the vehicle from being damaged. Further, when the vehicle collides with the light-emitting guide sign 100, the reflex force is applied to the vehicle with a certain degree of rigidity while the guide sign main body 10 is refracted, so that the vehicle collides with the light-emitting guide sign 100 to the driver. Can be recognized. Thereby, the overrun of a vehicle can also be suppressed.

<Light emitting part>
The light emitting unit 20 is provided on the upper part of the guide sign body 10 so that the driver can easily see the light-emitting guide sign 100 when the light-emitting guide sign 100 is installed. The light emitting unit 20 includes an LED 22, an LED substrate 23, and a lens unit 21 that collects irradiation light from the LED 22. In this embodiment, a plurality of LEDs 22 (specifically, a total of 12 vertical 4 × horizontal 3) are provided. Each of these LEDs 22 has R (red), G (green), and B (blue) emission sources, and the emission color can be freely changed. The lens unit 21 also functions as a cover that protects the LED 22.

  Here, some suitable specific examples of the light emitting unit 20 will be described. In the light emission part 20, the visibility when LED22 is light-emitting is so good that it is high. In addition, it is desirable to be able to prevent a decrease in visibility even when a vehicle collides.

  First, visibility can be enhanced by making the light emitted by the LED 22 less susceptible to external light such as sunlight (sunlight, daytime, western sun, etc.) and outdoor light. As an example for realizing this, it is possible to perform a satin treatment on the lens unit 21. The satin treatment may be performed on either the front surface or the back surface of the lens unit 21, or may be performed on either the entire surface or a part thereof (the portion through which the light of the LED 22 is transmitted). As described above, the entire surface or part of the front surface or the back surface of the lens unit 21 has a satin finish, so that it is possible to prevent external light from being irregularly reflected and light emitted from the LED 22 from being difficult to see from the outside. Moreover, an appropriate satin treatment that does not cause white turbidity also has an effect of scattering light and improving visibility. Further, as shown in FIG. 3, the distance A from the tip of the LED 22 to the inner surface of the lens portion 21 (the inner surface of the cover) is set to be sufficiently long (the distance A is set to be equal to or larger than the diameter B of the LED 22). The effect equivalent to the effect at the time of providing can be exhibited. Even with such a configuration, the light emitted from the LED 22 can be made less susceptible to external light.

  Further, even when the vehicle collides, it is possible to prevent the visibility from being deteriorated by suppressing the breakage of the lens portion 21 particularly on the portion through which the light of the LED 22 is transmitted. As an example for realizing this, there may be mentioned a configuration in which the surface side of the lens portion 21 is formed in an uneven shape, and a portion including a portion (that is, on the optical path) through which the light of the LED 22 is transmitted is a recess. For example, as shown in FIG. 4, four horizontal rows of concave portions 21 a are provided in accordance with the arrangement position of the LEDs 22 on the surface of the lens portion 21, or as shown in FIG. The surface side of the lens portion 21 can be formed into a concavo-convex shape by providing three rows of concave portions 21b according to the arrangement positions of the lens portions 21b. Thus, by making the surface side of the lens part 21 uneven, when the vehicle collides with the lens part 21, the vehicle collides with the convex part, so that the concave parts 21 a and 21 b are damaged. Can be suppressed. Therefore, the irradiation light from the LED 22 is not adversely affected, and a reduction in visibility can be prevented. In addition, when performing the said satin treatment, it is sufficient to perform only to the recessed parts 21a and 21b, and it is not necessary to perform a satin process to a convex part. In FIG. 4B and FIG. 5B, the shaded portion is the portion subjected to the satin treatment.

  What is necessary is just to use it combining suitably about performing the satin processing demonstrated above, setting the distance A from the front-end | tip of LED22 to the inner surface of the lens part 21 more than the diameter B of LED22, and making it uneven | corrugated shape. .

<Control related>
The control unit 50 performs drive control of the light emitting unit 20 based on detection results from the vehicle detection sensor 30 and the distance detection sensor 40. Here, a specific example of the vehicle detection sensor 30 can be an infrared sensor, and a specific example of the distance detection sensor 40 is an infrared laser rangefinder. The control unit 50 is configured to be supplied with electricity from a power source 60 provided outside such as a commercial power source (AC100V / 200V, etc.), a solar power source, a wind power generator, a hydraulic power generator, and the like.

<Description of operation (vehicle guidance procedure)>
In particular, a procedure for guiding the vehicle 500 will be described with reference to FIGS. 6 and 7.

As shown in FIG. 7, the light-emitting guidance sign 100 configured as described above is installed (fixed) in the back and center of the parking space 200 (particularly, the center position in the width direction of the vehicle 500 is desirable).

  When the vehicle 500 has not entered the parking space 200, the LED 22 of the light emitting unit 20 in the light emitting guidance sign 100 is turned off. When the vehicle 500 enters the parking space 200, the vehicle detection sensor 30 detects the vehicle 500. By this detection, the control unit 50 causes the LED 22 to emit blue (or green) light (turn on or blink) (see FIG. 6A). When the distance detection sensor 40 detects that the vehicle 500 has reached a certain distance (for example, 0.5 m or 1 m) from a predetermined stop position, the control unit 50 changes the color of light emitted from the LED 22. Turn yellow (see FIG. 6B). Furthermore, when the distance detection sensor 40 detects that the vehicle 500 has come to a predetermined stop position, the control unit 50 changes the color of the light emitted from the LED 22 to red (see FIG. 6C). Thereafter, when the distance detection sensor 40 detects that the vehicle 500 is at the stop position for a certain time (for example, 5 seconds), the control unit 50 turns off the LED 22.

<Excellent points of the light-emitting guidance sign according to this example>
As described above, according to the light emitting guidance sign 100 according to the present embodiment, the color of the light emitted from the LED 22 changes stepwise according to the distance between the guidance sign main body 10 and the vehicle 500. A person can easily grasp the sense of distance between the vehicle 500 and the guidance sign body 10. Therefore, the vehicle 500 can be moved to a predetermined stop position more reliably. Further, since the guide sign is installed in the back and center of the parking space 200, it can be used even if the parking space 200 has no margin. Further, since the guidance sign is in the center of the parking space 200, there is a guidance effect on the lateral width of the vehicle. Furthermore, even if the vehicle 500 exceeds the stop position, the vehicle 500 collides with the light emitting guidance sign 100, so that the guidance sign itself exerts a function of suppressing overrun of the vehicle. And when the vehicle 500 has not entered the parking space 200 and after stopping for a certain period of time, the LED 22 is turned off, so that useless power consumption can be prevented. Furthermore, since the light-emitting guidance sign 100 according to the present embodiment is fixed at a desired location, it can be prevented from being stolen.

  In general, the color of the light emitted by the LED 22 changes from blue or green to yellow, and from yellow to red. Then, “progress permission” is associated with blue or green, “caution” is associated with yellow, and “cannot proceed (stop)” is associated with red. Thereby, by changing the color of the light emitted from the LED 22 from blue or green to yellow, the driver can easily guess that the vehicle 500 is approaching the stop position, By changing the color of the light from yellow to red, the driver can easily estimate that the vehicle 500 has reached the stop position. Therefore, even if the driver has no knowledge about the light-emitting guidance sign 100 according to the present embodiment, the vehicle 500 can be accurately stopped at the stop position by the guidance sign.

  It is preferable that the driver recognize the position of the vehicle not only by light but also by sound. That is, when a sound generating means (for example, a buzzer) is provided and the vehicle detection sensor 30 detects the vehicle 500, the control unit 50 generates a sound simultaneously with the light emission of the LED 22. In addition, the control unit 50 changes the sound at the same time as changing the color of light. Accordingly, the driver can more easily recognize the position of the vehicle, and can move the vehicle 500 to the predetermined stop position more reliably. Examples of changes in sound include changes in timbre, changes in sound volume, and changes in sound generation intervals.

FIG. 8 shows a second embodiment of the present invention. In the first embodiment, the configuration in the case where the control for changing the color of the light emitted by the LED stepwise in accordance with the distance between the guidance sign body and the vehicle has been described. A configuration in the case of performing control to change the blinking interval of the light emitted by the LED stepwise according to the distance from the vehicle will be described. Since other configurations and operations are the same as those of the first embodiment, the same components are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  FIG. 8 is a schematic diagram showing a state where the vehicle is guided by the light emitting guidance sign according to the second embodiment of the present invention.

  In the present embodiment, the configuration and arrangement position of the light-emitting guidance sign 100 are the same as those in the first embodiment, and only the operation explanation (vehicle guidance procedure) is different from that in the first embodiment. Do.

  Also in the present embodiment, when the vehicle 500 has not entered the parking space 200, the LED 22 of the light emitting unit 20 in the light emitting guidance sign 100 is turned off. When the vehicle 500 enters the parking space 200, the vehicle detection sensor 30 detects the vehicle 500. In the present embodiment, the control unit 50 causes the LED 22 to blink by this detection. The color of light is not particularly limited, and any color may be used. The light blinking interval at this time is relatively long. For example, blinking is performed at a cycle of 1 second.

  When the distance detection sensor 40 detects that the vehicle 500 has reached a certain distance (for example, 0.5 m or 1 m) from a predetermined stop position, the controller 50 blinks the light emitted from the LED 22. To shorten. For example, it blinks at intervals of 0.5 seconds. Further, when the distance detection sensor 40 detects that the vehicle 500 has reached a predetermined stop position, the control unit 50 keeps the light emitted from the LED 22 lit. Thereafter, when the distance detection sensor 40 detects that the vehicle 500 is at the stop position for a certain time (for example, 5 seconds), the control unit 50 turns off the LED 22.

  As described above, the blinking interval of the LED 22 is shortened, so that the driver can easily estimate that the vehicle 500 is approaching the vicinity of the stop position. Then, by changing from blinking to lighting, the driver can easily guess that the vehicle 500 has reached the stop position. Therefore, even if the driver has no knowledge about the light emitting guidance sign 100 according to the present embodiment, the vehicle can be accurately stopped at the stop position by the guidance sign.

  As described above, also in the present embodiment, the same effect as in the first embodiment can be obtained. Also in this embodiment, it is preferable to provide a sound generating means to change the generated sound simultaneously with the change of the blinking interval.

  9 and 10 show Embodiment 3 of the present invention. In the present embodiment, a configuration in which a reflection sheet is provided in addition to the configuration of the first embodiment is shown. Since other configurations and operations are the same as those of the first embodiment, the same components are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  FIG. 9 is a front view of a light-emitting guidance sign according to Example 3 of the present invention. FIG. 10 is a partially broken cross-sectional view seen from the side of the luminescent induction sign according to Example 3 of the present invention. In FIG. 3, the left side from the center is a side view (partially perspective view), and the right side from the center is a cross-sectional view.

As shown in the drawing, in the light emitting guidance sign 100a according to the present embodiment, the guidance sign body 10 is provided with reflection sheets 71 and 72 for reflecting light. In the present embodiment, the reflection sheet 7 is formed in a region excluding the region where the light emitting unit 20 is provided, in the entire circumference of the guide sign body 10 in the circumferential direction.
1 and 72 are provided. Other configurations and vehicle guidance procedures are the same as those in the first or second embodiment.

  According to the present embodiment, in addition to the effects obtained by the first and second embodiments, the vehicle is brought to the vicinity of the light emitting guidance sign 100a based on the reflected light from the reflection sheets 71 and 72 even in a dark place at night. There is an effect that can be induced.

  11 and 12 show a fourth embodiment of the present invention. In the first to third embodiments, the configuration in the case where the detection means for sensing the vehicle and detecting the distance between the guidance sign body and the vehicle is a sensor provided in the guidance sign body is shown. Then, the structure in the case where the said detection means is a mat-like sensor provided in the part which a vehicle mounts separately from a guidance sign main body is shown. Since other configurations and operations are the same as those of the first embodiment, the same components are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  FIG. 11 is a partially broken cross-sectional view seen from the side of the light-emitting guidance sign according to Example 4 of the present invention. FIG. 12 is a front view of a light-emitting guidance sign according to Example 4 of the present invention. In FIG. 11, the left side from the center is a side view (partially perspective view) and the right side from the center is a cross-sectional view of the light-emitting guidance sign.

  The light emitting guidance sign 100b according to the present embodiment is provided with a mat type sensor 80 instead of the vehicle sensing sensor 30 and the distance sensing sensor 40 in the light emitting guidance signs according to the first to third embodiments. The mat type sensor 80 detects whether or not the vehicle 500 (tire 501) is mounted by turning on and off the switch by weight detection (pressure sensitivity).

  In this embodiment, the mat type sensor 80 is configured to detect whether or not the vehicle 500 (tire 501) is placed in each of the three regions. That is, the mat type sensor 80 includes a first sensor 81 that detects a region away from the guidance sign body 10, a second sensor 83 that detects a region near the guidance sign body 10, and detection of an intermediate region between them. The 2nd sensor 82 which performs is provided.

  The first sensor 81 is for detecting that the vehicle 500 has entered the parking space 200 and plays the same role as the vehicle sensor 30 in the above embodiment. Accordingly, the first sensor 81 is provided in the vicinity of the entrance of the parking space 200 (near the side opposite to the light emitting guidance sign 100).

  The second sensor 82 is for detecting that the vehicle 500 has come a certain distance (for example, 0.5 m or 1 m) from a predetermined stop position. Therefore, the second sensor 82 is provided at a certain distance from the stop position. The third sensor 83 is for detecting that the vehicle 500 has come to a predetermined stop position. Therefore, the third sensor 83 is provided at a desired stop position. These second sensor 82 and third sensor 83 play the same role as the distance sensing sensor 40 in the above embodiment.

  In this embodiment, unlike the distance detection sensor 40 in the above embodiment, the distance between the guidance sign body 10 and the vehicle 500 is not directly detected. The distance from the vehicle 500 can be detected.

As described above, also in the present embodiment, that the vehicle 500 has entered the parking space 200, that the vehicle 500 has approached a certain distance from a predetermined stop position, and that the vehicle 500 has a predetermined stop position. It is detected by the mat type sensor 80.

  Therefore, the vehicle can be guided to a desired stop position as described in the first and second embodiments. That is, the control unit 50 emits blue (or green) light from the LED 22 when the first sensor 81 detects the vehicle 500, and emits light from the LED 22 when the second sensor 81 detects the vehicle 500. When the third sensor 83 detects the vehicle 500, the color of the light emitted from the LED 22 is red. When the third sensor 83 detects that the vehicle 500 is at the stop position for a certain time (for example, 5 seconds), the control unit 50 turns off the LED 22. Alternatively, when the first sensor 81 detects the vehicle 500, the control unit 50 causes the LED 22 to blink light at a relatively long blinking interval (for example, a cycle of 1 second), and when the second sensor 81 detects the vehicle 500, the light is emitted from the LED 22. When the third sensor 83 detects the vehicle 500, the light to be emitted from the LED 22 is kept lit. When the third sensor 83 detects that the vehicle 500 is at the stop position for a certain time (for example, 5 seconds), the control unit 50 turns off the LED 22.

  From the above, it goes without saying that the same effects as in the first and second embodiments can be obtained in this embodiment. Of course, it goes without saying that sound generating means may be used in combination.
