Description

[Detailed description of the invention] [Industrial application field].

The present invention relates to a device that is installed in an elevator landing and displays the situation in which a car approaches the landing.

[Conventional technology]

Passengers who used to wait for their baskets to arrive at Kumeba 9.

He learned the location and driving direction of the car by the movement of the car position indicator, determined which car would be the quickest (the one that would be the fastest), and waited in front of the door of that car.

However, when there are a large number of cars installed, it becomes extremely difficult to find the desired car based on the ever-changing car positions and driving directions.
As shown in Publication No. 0266, the time required for a car that responds to one landing call to arrive at that landing is calculated,
This will be displayed at the landing area for each car as a predicted waiting time.

A method has been proposed to eliminate the anxiety and impatience of waiting customers by informing them how long they will have to wait for the basket to arrive.

However, this method of displaying the waiting time numerically (hereinafter referred to as the numerical display method) is

This has the advantage that it is easy for first-time customers to understand that the displayed content means the waiting time, but on the other hand, if the predicted waiting time and the current displayed content differ (This also had the problem of making customers feel distrustful and irritated.)

In addition, in order to solve the problems of the above-mentioned numerical display method, as shown in Japanese Patent Laid-Open No. 54-47261, a method ( A method (hereinafter referred to as a one-figure display method) has also been proposed. but.

Since this graphical display method graphically guides the approach of the car, it is difficult for passengers using this elevator for the first time to understand what the above display means (in the end, the effect of the above display is not fully understood). There was a problem that it could not be fully demonstrated.

Therefore, in order to make it easy for even first-time users to understand the above display contents, and to avoid causing a sense of distrust or irritation when changing the display contents, we have divided the display into two display areas that do not overlap with each other. A display device is provided inside the car or at the landing, and as the car approaches the landing, the display area (lighted area) of the first display area is gradually decreased, and the display area (lighted area) of the second display area is correspondingly decreased. It has been proposed to display the situation in which a car is approaching by gradually increasing the number of cars (Japanese Patent Application No. 60-88051, Japanese Patent Application No. 91527-1981, Japanese Patent Application No. 92572-1987, No. 117922, 1983.

See Japanese Patent Application No. 117923/1983]. This will be explained with reference to FIGS. 1 to 11.

Figure 7 is an overall configuration diagram to clearly show the configuration of the conventional example.
A is an approach situation calculation means that calculates and outputs the situation in which the car approaches the landing, and B is a display provided at the landing, which has three display areas B1B2 and B3 that do not overlap with each other.

C is a display control means that controls the lighting areas of the two display areas B1 and 82 of the display RWB and controls the display form of the nine display areas B3, and based on the output of the approach situation calculation means A,
As the car approaches the landing area, the lighting area of the first display area is gradually decreased, the lighting area of the second display area is gradually increased, and at the same time, the lighting form of the third display area is periodically changed. .

Figure 8 shows the landing on the third floor of a six-story building with two elevators, where DI and D2 are the doors of the first and second cars, respectively.

This is an indicator light belonging to .

FIG. 10 shows a display control circuit C1u that controls the uplink waiting time display 3jiUTM for the first car on the third floor among the display control means C.
FIG. Similar circuits are used for the descending direction, other floors, and other cars. In the figure, αri is a well-known allocation device that allocates up calls and down calls registered by hall operation panel H etc. to car No. 1 or No. 2 and outputs an allocation signal. This is an assignment signal that becomes rHJ when assigned to an uplink call and becomes rLJ when the 9th assigned car responds to the above call.

a3 is the predicted value of the time required for Car 1 and Car 2 to arrive at each landing on the 1st to 6th floors in the up and down directions in response to the car call and the assigned landing call, respectively (i.e., the expected arrival time) using a well-known expected arrival time calculation device that calculates and outputs each.

ltl is the expected arrival time signal (in 5-second increments) for the 3rd floor of the No. 1 aircraft. B4 is a car control device for car No. 1 that controls running operations such as determining the driving direction and running/stopping, as well as door opening/closing operations in order to respond to calls.

(143u) is output from the car control device α4 of the first car.

When the first car arrives at the third floor in the upward direction in response to a call from the third floor, the signal immediately after arrival becomes rHJ only from the time of arrival until the door is fully opened. c2υ~Iso is the input signal at point X≧Y
When the human input signal of the point is obtained, the output signal of the two points is set to "H",
In other cases, the comparators that output signals at two points are rLJ, and Tl to T5 satisfy the relationship TI<T2<T3<T4<T5.

It is a gate.

FIG. 11 is a diagram showing changes in the display state of the uplink waiting time indicator UTI in FIG. 9. (However, the shaded area indicates the lighting state.) Next, the operation of this conventional example will be explained.

Assume that a waiting customer operates the up button on the third floor to register an up call, and the 9 allocation device a'a allocates car No. 1 to this call. At this time, the 3rd floor ascending assignment signal (115u) of Unit 1 is r
Becomes HJ. On the other hand, suppose that the expected arrival time calculation device Q3 calculates and outputs the expected arrival time signal 1tl for the 3rd floor uphill of the No. 1 car as 25 seconds.

Since the outputs of the comparators 0υ~(c) are all rHJ, the outputs of the AND gates C3υ~(to) are also rHJ, and the indicator lamps (11~(5)) in the first display area B1 are lit.

On the other hand, since the outputs of NOT gates 1511 to 551 are all rLJ, the output of AND gates (to) to book is also r
Since the signal immediately after arrival (145Lj) is also rLJ, the output of OR gates 4 to 49 also becomes rLJ and the second
The indicator lights (61 to α1) in the display area B2 remain off.

Also, while the one-period pulse signal (5oa) is “L”, AND
The output of gate I is rLJ, the output of NOT gate (S1 is "H", and the output of AND gate 0 is rHJ, so the 2nd indicator lamps (11A) and (11C) are turned off and the indicator lamp (N13) is turned off.
) and (11D) are lit. Conversely, the periodic pulse signal (s
While oa) is rHJ, the output of AND gate I is rHJ,
The output of NOT gate (561 is rL, J, and the output of AND gate L4X5 is rLJ, so 9 indicator lights (11, A
) and (11C) are lit and indicator lights (119) and (11
D) is turned off. In the end, the indicator light (1
1A) and (11G) and indicator light (1113) and (
The set 11p) alternately turns on and off every 0.5 seconds. This flashing indicates that the hourglass is falling. This blinking is caused by the assignment signal (11su) being rHJ.
will continue for a period of time. In this way, when the expected arrival time signal 11+ takes a value greater than the constant value signal T5, the lal in FIG.
The state shown in is reached. (899 indicator light 11A) ~ (11
(D) flashes) Next, Unit 1 approaches the 3rd floor and the estimated arrival time signal 1tl
Suppose that the time period changes from 25 seconds to 20 seconds. At this time, t(
= 20 seconds) < 75 (-21 seconds), and only the output of comparator ① becomes rHJ - rLJ.

The output of the AND gate (to) becomes rHJ → rLJ.

The indicator light (5) in the first display area B1 is turned off. At the same time N
Since the output of OT game) 1551 becomes rLJ - rHJ, the output of AND gate (to) becomes rLJ → "H", and the output of OR game) E becomes rLJ → "H".

The indicator light (6) in the second display area B2 lights up. Therefore.

The display state of the display UTI at this time is lal as shown in Fig. 11.
It changes from to lbl.

Furthermore, Unit 1 approaches the 3rd floor and the expected arrival time signal +1
If + changes from 20 seconds to 15 seconds, 10 seconds, and 5 seconds, the outputs of comparators c+a, ca, and a will become rH in order.
As the output of the AND gate 1, c (hot water changes to "H" - rLJ, A
ND game) B71. C! 8. ((I(7) output goes from rLJ to rHJ in order, OR game) 14fi, +47),
The four outputs become rLJ - rHJ in order. Therefore, the first
The indicator lights (4) and +31.121 in the display area B1 go out in order, and the indicator lights in the second display area B2! 73. +8
1. +91 lights up in sequence. Therefore, when the expected arrival time signal 1tl changes from 20 seconds to 5 seconds, the display state of the 1 display tJT1 changes from lbl to tcl in FIG.
, lal, tel.

When Unit 1 arrives on the 3rd floor in the upward direction, the 3rd floor upward call is canceled, the assignment signal (113u) becomes rLJ, and at the same time the immediately after arrival signal (145u) becomes rHJ, and the expected arrival time open signal 1tl becomes 0 seconds. Become.

Therefore, the outputs of the AND gates Gυ~A3 are all rLJ, so the indicator lights (11~(5)) of the first display area B1 and the indicator lights (11A)~(11D) of the third display area B3 are all turned off. Also, the signal (143u) immediately after arrival is rHJ
Therefore, the outputs of OR gates 4 to 4 all become rHJ, so the indicator lights (6) to 111) in the second display area B2.

All lights up. At this time, the display state of the 9 display UTI changes to tel 1 in FIG.

Finally, when Unit 1 starts opening the door at 3Wt, the signal immediately after arrival (143u) becomes rLJ, and the outputs of OR gates 4 to u9 all become rLJ, so the indicator lights (6) to Q( It will be in the same state as Moe where all I lights are turned off and the hall call is registered.In addition, when the up call for the 3rd floor is assigned to the 2nd car instead of the 1st floor (assignment signal (1t3u)
) = rLJ, since the outputs of AND gates 00 to 0 are all "L", the display 1UT1 of the first car remains off, and the passengers waiting for the second car are not confused.

In this way, in the above conventional example, when the expected arrival time signal 1t+ becomes smaller as the car approaches, the first display area B
Reduce the area where the first indicator light is lit, and at the same time reduce the area where the second indicator light is lit.
The area where the indicator lights in the display area B2 are lit is increased from zero.

The approach status of the car is displayed in an hourglass-like display format, so that even first-time customers can understand the displayed content.

[Problem that the invention seeks to solve]

However, the above-mentioned waiting time display is expensive;
In addition, in the conventional example 2 above, it is necessary to install one set of upstream waiting time indicators UTI and UT2 and one set of downstream waiting time indicators LT1 and LT2 for each car and each floor, so it is difficult to put it into practical use because of the cost. There was a problem. In addition, when there are waiting customers going in both directions, up and down, and the hall lantern indicates that the same car will be serviced, the waiting customers will see the up and down waiting time indicators. It is necessary to always keep in mind whether the car arrives first in the up or down direction.

This placed a psychological burden on waiting customers.

This invention was made in order to solve the above-mentioned problems.It uses a display divided into two display areas to guide the approaching situation of a car.2 It is possible to reduce costs and reduce waiting time. To obtain an elevator display device that does not impose unnecessary psychological burden on customers.

[Means for solving problems]

The device according to the present invention divides a display provided in an elevator landing into two display areas, gradually reduces the lighting area in the first display area as the car approaches the landing, and reduces the lighting area in the second display area. In the case where the area is gradually increased, the calculation means calculates and outputs the distance or time required for the car to arrive at the landing area for each direction, and the selection means selects between the outputs of the calculation means in the upward direction on the same floor. Compare the distance or time in the downward direction, select the direction in which the distance or time is smaller, set the distance or time in the selected direction, and use the first display area means to select the direction in which the distance or time is smaller. A quantity corresponding to the distance or time is displayed in the lighting area of the first display area and is also displayed in a form corresponding to the direction selected by the selection means, and the second display control means selects the direction set by the selection means. The lighting area of the second display area is increased as the distance or time decreases, and the area is displayed in a display format corresponding to the direction selected by the selection means.

[For production]

The device according to the present invention calculates the distance or time required for the car to arrive at the landing for each direction.

Compare the above-mentioned distance or time in the upward and downward directions on the same floor, select the direction in which the above-mentioned distance or time is smaller, and set the distance or time in the selected direction, and display it at the above-mentioned landing. In one display area of the device, the distance or time required for the car to arrive at the landing area is indicated by the illuminated area, and this is also displayed in a form corresponding to the direction selected above, and in the other display area. As the set distance or time decreases, the lighting area is displayed to increase, and this is displayed in a display format corresponding to the selected direction.

11Ad) to (41Dd) is a downward indicator light lighting signal that becomes rHJ.

FIG. 6 is a circuit diagram showing a hall lantern control circuit C4 that controls the hall lanterns U1g and L1 for the No. 1 machine on the third floor of the display sub-section means C. Similar circuits are used for other floors and other cars. In the figure, 17

, (The shoulder is an OR gate.

Next, the operation of this embodiment will be explained.

Customers waiting on the third floor operate the up button to register an inbound call.

Assume that the allocation device (13) allocates car No. 1 to this call. At this time, assume that the 3rd floor down call is not registered.

The third floor down assignment signal θ13d) of the first car becomes rLJ, and the third floor up assignment signal (113u) becomes rHJ. Therefore, the sixth
The up hall lantern U1 is turned on by the OR gate 1) of the hall lantern control circuit C4 shown in the figure, and the waiting customers are informed that the No. 1 car is assigned to the up call. Also, if Unit 1 has not arrived at the 3rd floor, the arrival signal (1s3u)
.

(1s3d) are all rLJ, so in Fig. 4
, NOTOR gate 15'l in selection device D13
The outputs of 1701 and (67) both become rHJ. Therefore.

The output of the AND gate +621 also becomes rHJ, and the output of the OR gate (depending on the phrase, the up display command signal (6Sa) becomes rHJ. Also, the output of the AND gate (641) also makes the falling display command signal (64a) rHJ.
1° (Since both phrase outputs are rLJ, the downward display command signal (66a) remains rLJ.

On the other hand, if the expected arrival time signal (tu) of Unit 1 going up to the 3rd floor is calculated and output as 25 seconds by the expected arrival time calculation device 0, then the rHJ signal is manually input to the T1 point of the 1 selection circuit (to). Therefore, the expected arrival time signal 1tl from point P
is set to 25 seconds and output. Therefore, the output of the comparator (C) of the display control circuit C13 in FIG.
The indicator light (5u) in the first display area B1 lights up in green. Similarly, the outputs of comparison aaυ~@ are both r
HJ, all uplink indicator light lighting signals (alU) to (a4U) are set to r by the switching circuits te11 to te11 (841).
HJ is output, and the indicator lights (1u) to (4u) also light up in green.

Furthermore, the outputs of the NOTOR gates 1511 (551) are all rLJ, the outputs of the switching circuits (e61 to (901) are all rLJ, and the indicator lamps (6
u) to (+ou) and (6d) to (1od) remain off.

The display state of the display WTI at this time is tal in FIG.
As shown in , the green light notifies passengers waiting at the boarding point that the waiting time for the upbound direction is displayed. 2. This is because both the falling display command signal (64a) and the rising display command signal (65a) are "H".

The uplink indicator light lighting signal (91u) is generated by the switching circuits 191+ and 1921.

(v2u) repeats rHJ and rLJ, so the 9 indicator light (
NAu) ~ (11pu) repeats blinking in green alternately at 0.5 second intervals as in the conventional example, indicating that the upward direction display in the first display area B1 and second display area B2 is progressing. I will guide you to.

Next, Unit 1 approaches the third floor and the expected arrival time signal is 1tl.
is 25 seconds, then 20 seconds, 15 seconds, and 10 seconds.

If it changes from 5 seconds to 0 seconds, the comparator (to), C24
Since the outputs of ゜(c), a, and aυ become rHJ → rLJ in order, the indicator lamps (5u) t (4u
), (3u).

(2u) and (1u) turn off in sequence every 5 seconds. Along with this, NOTOR gate 1551ls4.1551.
The output of 1521.151 changes from rLJ to rHJ in order, and the uplink indicator light lighting signal (86u), (
87u), (88u), (89u).

(9ou) becomes rL"-rHJ in order, and the same (indicator light (6u) + (7u) + of the second display area B2 every 5 seconds.
(8u)# (9u)j (+Ou) lights up in order. in the end.

When the expected arrival time signal ttl changes from 25 seconds to 0 seconds, it changes from lal to tb+, (cL tag, tea, lfl) as shown in FIG. 11, as in the conventional example.

The lighting color is green.

Then, when Unit 1 arrives at the 3rd floor in the upward direction, the 3rd floor upward call is canceled and the assignment signal (+1SU) becomes rLJ and at the same time the arrival signal (1s3u) becomes rHJ.
The outputs of AND game) tal, t@, and (64I) are all rLJ, but the uphill display command signal (6ha), which is the output of the OR gate (gradient), will maintain "H".At this time, the falling display command The signal (64a) becomes rLJ. Therefore, even if the expected arrival time signal (tl is a value of 1 second or more, the indicator lights (1u) to (5u) in the first display area B1
, and indicator lights (11Au) to (11Au) in the third display area B3
Du) go out all at once, and the indicator lights (6
u) to (1ou) are all lit. Also, in the hall lantern control circuit C4 of FIG.

Since the upstream arrival signal (1sxu) becomes rHJ, AND
Gate +751. Periodic pulse generator (741,3 and O
The up hall lantern U1 blinks due to the R gate (771).

After that, when the car completes opening the door and a certain period of time has passed, it starts closing the door, and when the car completes closing the door, an upstream arrival signal (1s
3u) becomes rLJ, the output of the OR gate (δ) becomes rLJ, and the upstream display command signal (6Sa) becomes rLJ. Therefore, the uplink indicator light lighting signal (a6u) ~ (9o
u) becomes "L" and the indicator light (6u) of the second display area B2
~(1ou) are all turned off, the up hall lantern U1 is also turned off, and the state is the same as before the 9 hall call was registered.

The same applies if only the third floor down call is registered.

This time, the indicator lights (1d) to (sd) in the first display area B1
.

Indicator lights (6d) to (1od) in the second display area B2 and indicator lights (41Ad) to (11Dd) in the third display area B3
The waiting time in the down direction will be displayed by lighting red.

In addition, when Unit 1 is assigned to the 3rd floor up call (the up hall lantern U1 is lit) and the 3rd floor up expected arrival time signal (tu) is 20 seconds (11 in Figure 11), When the No. 1 car responds to the car call on the 3rd floor and arrives at the 3rd floor in the down direction, the down arrival signal (1ssd) becomes rHJ, so the output of NOT game M7G+ becomes "LJ, and the output of AND game IJ21 becomes rLJ" and goes up. Display command signal (s
ea) changes to rHJ-rLJ, OR age-t6
The downward display command signal (66a) is changed from “L” to r via 6+.
Changes to HJ. Also.

A fall display command signal (64
a) changes to rHJ-rIl. Therefore, the third floor expected arrival time signal (tl) is set to the downward expected arrival time signal (td) (=0 seconds) by the selection circuit (to).

Upward indicator light lighting signals (%u) to (92U) are all rLJ
The upstream indicator lights (su) ~ (1au), z and (11Au) ~ (11Du) are all turned off, while the outputs of the comparators Qυ ~ (c) are all rLJ, so in the end, the downstream indicator light lighting signal ( a6d) ~ (wod) only rHJ
Next, the downbound indicator lights (6d) to (4od) light up in red, and the downbound hall lantern L1 flashes to notify passengers of the downbound arrival of the car (state (f) in FIG. 11). Then, the car door is opened, closed again, and the downbound arrival signal (+53
d) becomes rLJ, the uplink display command signal (SSa
) is set to rHJ, and the fall display command signal (64a) is set to rHJ.

The descending display command signal (66a) becomes rLJ, and the expected arrival time signal (tl is the expected arrival time signal for going up to the third floor at the time when the door is closed (tu) (=10 seconds) is set, as shown in Fig. 11. (Display in the upward direction will be restarted from the state of di.

In this way, when only one hall call is registered, the direction of the registered hall call is displayed, and if the car arrives first in the opposite direction in response to a call, the direction of arrival is displayed (= By temporarily switching to the state (when all the sand in the hourglass has finished falling), it is no longer possible to accidentally board a car in the opposite direction.

Next, when Unit 1 is assigned to the 3rd floor up call and the 3rd floor up expected arrival time signal (tu) is 20 seconds (state (bl) in Figure 11), a 3rd floor down call is newly registered and this Assume that the call is also assigned to Unit 1.If the expected arrival time signal (td) going down the third floor at this time is 40 seconds, the comparator ■
Since the output of is "H" and the output of the comparator is rLJ,
At the same time when the output of AND gate 1621 becomes rLJ,
The output of the ND gate (ω1 becomes rHJ, and the uplink display command signal (6Sa) that is the output of the OR gate (A1) becomes rHJ.
HJ is maintained, and the waiting time indicator WTI continues to display the upstream waiting time.

If the expected arrival time signal (td) going down the third floor is 10 seconds, the output of the comparator (to) will be rLJ, and the output of the comparator (to) will be rLJ.
Since the output of the AND gate (611) becomes rHJ, the output of the AND gate (611) becomes rHJ, and the downward display command signal (66a) becomes rLJ - rHJ via the OR gate (611).

On the other hand, the output of AND gate [621 becomes rLJ, so OR game] (upward display command signal (SSa
) becomes "H" - "L". Therefore, the waiting time indicator WT
I changes from the upstream waiting time display (11 in Figure 11) 1 status 1 lighting color = green) to the downstream waiting time display (11 in Figure 11).
The state 9 of ldl shown in the figure is switched to the lighting color (red). Then, when the first car arrives in the down direction and the door has been closed, the display of the waiting time for the up direction will be resumed in the same way as in the case of the above-mentioned arrival.

In this way, in this embodiment, when both an upbound hall call and a downbound hall call are registered on the same floor, it is determined which direction will arrive first, and the waiting time for that direction is displayed as one waiting time. This is done on the display and the display format is switched according to the direction, so costs can be reduced.Moreover, the above-mentioned waiting customers can compare the up-bound waiting time display with the down-bound waiting time display and see which car comes first. There is no longer a need to always be aware of whether you are arriving in the up or down direction.

It is possible to eliminate the burden on waiting customers.

In the above embodiment, the situation where the car approaches is displayed in the first display area as a predicted value of the time until the car arrives at the landing, that is, the expected arrival time, and the lighting area of the second display area is Although the lighting area is determined and displayed so as to be equal to the unlit area of one display area, the method of representing the situation in which a car approaches is not limited to this. As a predicted value of the approach situation of the car, for example, as specified in Japanese Patent Laid-Open No. 52-5141, the number of floors that must be traveled before arriving at the landing in a predetermined direction may be used. Good, and it is also easy to use the planned number of floors at which the train must stop.

Further, the display method in which the lighting area in the second display area increases as the lighting area in the first display area decreases is not limited to this embodiment.

As shown in Japanese Patent Application No. 61-117922, there is a method in which the lighting area of the second display area always starts from the minimum area regardless of the length of the expected arrival time;
As shown in No. 92572, the present invention can also be applied to a system in which the expected arrival time is displayed in a first display area and the amount of decrease in the expected arrival time after 9 display starts is displayed in the second display area. .

In addition, in the above embodiment, in order to make it easier for passengers to understand in which direction the waiting time is displayed on the 1 display, when the direction in which the car will arrive first is the up direction, it will turn green; Although the lighting color is changed to "red" when the direction of arrival is the down direction, the method of changing the display form depending on the direction is not limited to this. For example, the display area (
In addition, when displaying the upward direction, the predicted arrival time is displayed in the lower display area B2, and the amount of decrease in the predicted arrival time is displayed in the upper display area B1, and when the downward direction is displayed, the predicted arrival time is displayed in the upper display area B1. Sometimes, contrary to this, a method may be considered in which the positional relationship of the display areas is varied, such as displaying the estimated arrival time in the upper display area B1 and displaying the amount of decrease in the above estimated arrival time in the lower display area B2. .

In addition, in the above embodiment, when only one hall call is registered, the direction of the registered hall call is displayed, and when the car arrives first in the opposite direction in response to a call, the direction of arrival is displayed. (≠ the state in which all the sand in the hourglass has finished falling), but the display of the direction of the registered hall call will not be changed even if the car arrives in the opposite direction. is also easy.

Furthermore, in the above embodiment, the approach status of the car is displayed in six stages, but the number of display stages is not limited to this. LED, liquid crystal, and plasma displays,
Furthermore, it is clear that the approach situation can be displayed in more detail by using a graphic display using a CRT. In addition, we use multiple types of lighting colors for the display, and use parts that should be turned off (
Even if the background (background) is displayed in a different lighting color, the effects of the present invention will not be impaired.

Furthermore, in the above embodiment, the 9-indicator was configured to resemble an hourglass, but it does not necessarily have to be made to resemble an hourglass. If the display area of the display device is divided into two display areas, and as the car approaches the landing area, the lighting area of one display area gradually decreases, and the lighting area of the other display area gradually increases. The approach situation of the car can be easily understood by association.

〔Effect of the invention〕

As described above, according to the present invention, a display provided at an elevator landing is divided into two display areas, and as the car approaches the landing, the lighting area in the first display area is gradually reduced, and In one in which the lighting area in the second display area is gradually increased.

The calculation means calculates and outputs the distance or time required for the car to arrive at the landing for each direction.

The selection means compares the above-mentioned distance or time in the upward and downward directions of the same floor among the outputs of the above-mentioned calculation means, selects the direction in which the above-mentioned distance or time is smaller, and also calculates the distance or time in the selected direction. setting, and the first display control means displays an amount corresponding to the distance or time set by the selection means in the lighting area of the first display area, and also displays this in a form corresponding to the direction selected by the selection means. The second display control means increases the illuminated area of the second display area as the distance or time set by the selection means decreases, and displays this in a display form corresponding to the direction selected by the selection means. Since the system is configured to display this, it is possible to reduce costs and eliminate unnecessary psychological burden on waiting customers.
