2. Description of the Related Art A navigator is a device for guiding a person or an object. In the past, the light of lighthouses and lanterns played a role, and recently GPS (Global Positioning System)
There is a car navigation using. However,
Currently, directions from the nearest station to your company rely on signboards. The current situation can be recognized from the group of company information signs at the nearest station. Around the concert venue, we often see people walking right and left without finding the venue just before the opening time. In some cases, they may have lost their way because they overlooked the guide sign at the nearest station because they were in a hurry, or they might be lost because they had missed the so-called route to shop along the way. Sometimes they find accidents in unfamiliar lands looking for signboards, cross an unreasonable road and have an accident.

[0003]

SUMMARY OF THE INVENTION Navigation using GPS requires an expensive device to receive a signal from a satellite and detect its own position. In addition, there was also a problem that did not work where radio waves could not reach. On the other hand, in concert halls and companies that welcome visitors from multiple people, signs are installed at the nearest station or signs are installed on the main route to guide, that is, navigation, but signs are used. Many visitors get lost because they miss it. The focus on finding signboards has made it easier for traffic accidents and sprains to occur. In a situation where a large number of spectators are crowded together at the time just before the start, such as in a concert venue, there is a disadvantage that only the route shown on the signboard of the guide is abnormally crowded. There is a case where a guide member is arranged for the purpose of compensating the above problem, but there is a problem that human cost is generated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment corresponding to claim 1 of the present invention will be described with reference to FIG. FIG. 1 is an example of a navigator 1 prepared for guiding customers to a showroom operated by a trading company. The navigator of FIG. 1 is also enclosed when sending the invitation to the showroom to the customer. The navigator weighs 200 grams and measures 20 cm wide by 15 cm high by 5 mm thick. The navigator is used in a section where the user comes on foot from the nearest train station to the showroom. The customer turns on the navigator after arriving at the nearest station on the guide letter and starts using the navigator. When the customer arrives at the showroom, it is collected at the reception and reused the next time another guest is invited.

The navigator 1 has a display function 2 comprising an STN liquid crystal display. A detachable destination information card 3 in which road information of a section connecting the showroom and the nearest station is written is inserted. The card writes the most suitable information according to the purpose and the customer. The position detection function 4 is a method of receiving a radio wave from a dedicated transmitter. As the position detecting function, a method of receiving a local radio wave of the PHS and calculating its own position may be implemented. In some cases, an autonomous driving system using a GPS or a simpler device combining a compass and a pedometer similar to a pedometer may be used.

The display screen of the display function will be described. The current position is three-dimensionally drawn by the one-point drawing method as the lower side of the screen. Intersection position 5 which is a branch point in the traveling direction
Is drawn in the center of the screen. This intersection is a five-way intersection. An arrow instructing progression from the lower side of the screen toward the intersection is drawn, and a distance display 6 to the intersection is displayed inside the arrow. Two arrows are drawn from the intersection. An arrow indicating the optimum traveling direction 7 and a hatched arrow indicating the possible traveling direction 8 are shown. 2 left
Since it is difficult to reach the destination when heading in one of the traveling directions, the crossing direction is drawn as a non-traveling direction 8 with a cross. The target 10 is drawn near the intersection,
It is useful for reconfirming that the customer being guided is a compatible intersection. The target is, for example, a convenience store. Even if you are away from the intersection, it may be drawn as a target around the route as convenient information for the customer. The screen scroll button 11 can be used to look back at the point when switching and revising the intersection that has been passed up to now, or in advance, when selecting the optimal traveling direction or the possible traveling direction, the intersection that appears next is set in advance. Used when you want to know. When a future intersection is displayed, a route to be selected is selected on the liquid crystal screen of the display function, and then the scroll button is pressed.

An actual method of using the navigator will be described with reference to FIG. FIG. 2 is a block diagram showing a method of using the navigator according to claim 1 of the present invention. The customer 12 being guided with the navigator 1 shown in FIG.
The situation is approaching the lane. A dedicated position information transmitter 1 is placed on a telephone pole 14 disposed adjacently.
5 are installed. A signal 16 is transmitted from the position information transmitter as a weak local radio wave. When the customer approaches the T-junction, the navigator receives the signal and automatically sounds a buzzer. The range in which the buzzer sounds is adjusted by the strength and directivity of the signal and the reception sensitivity of the navigator. For example, the buzzer sounds when reaching a range of a radius of 5 meters around the T-junction. After the buzzer sounds continuously for 5 seconds, the buzzer does not sound again within the range of the T-junction.

The customer guided by the sound of the buzzer sees the screen of the navigator. On the liquid crystal screen, a screen similar to that illustrated in FIG. 1 is drawn. In the example of FIG. 2, it is not a five-junction but a T-junction. According to the instruction of the optimal traveling direction, for example, the user turns to the right in the traveling direction and walks further. In this example, the position information transmitter has a function of detecting the timing at which the signal of the pedestrian crossing changes, and also transmits service information for changing the optimum traveling direction according to the timing and displaying it to the customer. I have. The navigator changes the optimal traveling direction according to the information.

An embodiment corresponding to claim 2 of the present invention will be described with reference to FIG. The navigator 1 of FIG. 3 is distributed to guide spectators from the nearest station to the concert venue. The navigator starts the guidance operation by having the power turned on when arriving at the nearest station. The ON timing is, for example, the moment when the vehicle passes through an automatic ticket gate. The navigator detects a weak radio wave emitted from the automatic ticket gate and recognizes the ticket gate. When the power supply of the user is automatically turned on, a first voice of guidance is first emitted from the speaker 17. It says, "I'm just past the east exit ticket gate. Go straight for about 100 steps (70 meters) and go out on the rotary." The distance is displayed in steps so that people can easily count. However, since the number of steps varies depending on the individual difference and the state thereof, the built-in pedometer for each appropriate landmark is compared with the actual walking distance to be calibrated and reflected in the next step number display.
The number of steps to the next target (rotary) is also displayed on the display function 2 which is a liquid crystal screen. In the step number display, the remaining step number to the destination is displayed by a countdown method. The destination information card 3 also contains information on nearby shops and return transportation, as well as notes on the venue, descriptions of concerts, and various commercials. Washed away from. For example, shop information is sent when the user comes near the shop.

A first embodiment of the present invention will be described with reference to FIG. FIG. 4 shows a pre-arranged display function 18 embedded in the manhole cover at the center of the T-junction 13. In the display function, arrows are drawn in three directions corresponding to the T-shaped intersection. When the customer 13 approaches the T-junction with the navigator 1, in response to the signal 16 transmitted from the navigator, the arrow 19 of the optimal traveling direction among the arrows shines to indicate the traveling direction. I have. Information indicating which arrow of each display function is illuminated in advance is written in a built-in IC card.
The IC card is detachable.

A second embodiment of the present invention will be described with reference to FIG. Figure 5 shows the nearest station 20 and destination 2
3 is a map showing a positional relationship with the position No. 1; The destination is a bargain venue, which has three entrances: A, I and C. At three intersections, which are branch points, a display function 18 arranged in advance on a manhole cover is provided. The display function and the navigator arranged in advance in FIG. 5 have almost the same functions as those in FIG. When the customer being guided approaches each branch point, it flashes an arrow and indicates the direction to go. In the example of FIG. 5, a function of changing the arrow display in consideration of the degree of crowding of the three entrances is added. As an example of the method, a display function arranged in advance has a function of counting the navigators passing through each branch point, and the number is compared with the permissible number of passers at each entrance, and is assigned to each entrance. The simplest method of sorting is that the first passer is guided to the entrance of A, the second is A, the third is C, and the fourth is A, 5
The third is a method of evenly distributing in the order of a.

FIG. 6 shows an embodiment corresponding to claim 4 of the present invention. FIG. 6 shows a subway exit as the nearest station 20 and a company location as the destination 21. A range substantially equivalent to a rectangular range having a diagonal line between the shortest road connecting the exit of the subway and the destination is surrounded by a dotted line as a permissible range 22. A plurality of display functions 18 arranged in advance are arranged on the road on the side of the traffic allowable range.

As shown in FIG. 6, roads are often arranged in a grid pattern in an office district in a downtown area. In this case, there are a plurality of optimal routes from the exit of the subway to the company. This is shown in FIG. In the situation of FIG. 6, it is often the case that it is rather confusing to guide a visitor with a certain degree of freedom. Avoiding restrictions is less confusing, especially for navigation for customers who have some knowledge of the city. In this situation, a permissible traffic range is set as indicated by the dotted line, and a warning is issued only when the permissible range is exceeded. Although not shown, when the customer who owns the navigator of the present invention roams the range of FIG. 6, when the customer approaches the display function arranged in advance, a warning that the range is exceeded is issued. .

[0016]

When the navigator of the present invention is used, a plurality of routes can be selected at an intersection or the like to be judged in the navigator of the first aspect. If you select within the indicated range of progress, it is guaranteed that you will reach your destination, so you can select with confidence. The priority order is also indicated for the traveling direction, so that when the user wants to reach the destination most efficiently, he or she does not make a wrong choice.
In the case of claim 2, the security is further improved by being notified by voice. And it becomes possible to transmit much more information from the navigator to the customer. In the case of the third aspect, by having the display function arranged in advance, the restriction condition that the display function has portability can be removed. Thus, an ideal display can be performed without being limited by the battery and the display area. In addition, by fixing to each place, navigators passing therethrough can be easily counted, and navigation using the count information can be performed. In the case of the fourth aspect, by guiding the passengers based on the concept of the allowable traffic range, it is possible to effectively guide the customers who have existed to some extent.
