Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a map, and more particularly to a road map having a bar code representing the scale and speed of the map used by a driver of a vehicle.

<Prior Art> Drivers of automobiles often drive while referring to road maps. In many cases, the distance between important points is marked on the road map, but information about the points actually traveling is often lacking.

As a method of obtaining the distance between arbitrary points on a map, there is a method of tracing a desired route with a map meter, obtaining a moving distance of the meter, and multiplying the scale of the map to calculate the distance. For example, if the distance traveled on a map of 1 / 100,000 is 10 cm, the actual distance is 10 (cm) x 10000.
It is 0 = 1,000,000 (cm) = 10 (km). But 2
There was no easy way to calculate the time required between points.

<Problems to be Solved by the Invention> An object of the present invention is to provide a map capable of easily and surely knowing the time required to move on an arbitrary route on the map.

<Means for Solving Problems and Their Actions / Effects> In view of the problems of the above-mentioned conventional technology, the present invention marks the map scale and the bar code for setting the traveling speed on the map, and the bar code reading unit is provided. By reading the bar code with the provided map meter, the scale and traveling speed are automatically read,
While converting the measured distance between two points on the map to the actual distance,
It is possible to display the time required for traveling during this period. If the driver moves the map meter along the desired route after reading the bar code indicating the scale and traveling speed on the map, the corresponding required time is immediately displayed.

<Example> FIG. 1 shows a map which is the basis of the present invention. Terrain display section 1
A scale display section is provided below 1. In the scale display section, a scale ratio display 15, which indicates a scale of the map,
A reference distance display graph 17 indicating how long the reference distance is on the map is provided, and a bar code 13 in which a scale factor is displayed by a bar code is provided.

The gist of the present invention is to provide a barcode having such a bar code representing the scale of the map with a bar code representing the speed.

FIG. 2 shows a bar code representing such a traveling speed. The traveling speed may be read by one reading or a combination of plural readings. In the illustrated case, the combination is read. The read speeds are added and reset to zero. For example,
115km / h when reading 100km / h, 10km / h, 5km / h
You have read If you have made a mistake and want to change the set speed, you can read the reset 25.
Although the mileage display 29 is shown together with the kilometer display 27, it is obvious that either one may be displayed.

FIG. 3 shows a map meter 30 suitable for use in combination with the present invention. A distance measuring unit 31 is provided at one end of the meter 30. The moving distance is measured by moving the tracing stylus 33 along the desired route. A bar code reading section 35 is provided at the other end of the meter 30. The reading unit may read the entire barcode at once, or may read the barcode by moving the reading unit 35 onto the barcode. The latter is often more convenient for realizing a compact meter. A liquid crystal display 37 is provided at the center of the meter 30. By moving the tracing stylus 33 of the meter 30 on the map, the display unit 37 displays the distance in the real space corresponding to the route read on the map and the time required when the route travels at the set speed. It A set button 39 is provided on the right side of the display unit 37 so that the operation of the meter and the selection of the operation mode can be designated.

A method of measuring the distance from the point A to the point B in FIG. 1 and the required time by using the meter in FIG. 3 and the map in FIG. 1 provided with the bar code in FIG. 2 will be described.

First, find the desired figure 1 in the map book and open it. When the set button 39 of the map meter is pressed, a message supporting scale reading is displayed on the display unit 37. Therefore, the barcode reading unit 35 is set to the scale display barcode 1
3 Move up and read scale. The read scale is displayed on the display unit 37, and when the traveling speed is subsequently set, a message indicating that the set button is pressed is displayed. When the set button 39 is pressed to read the traveling speed setting bar code and the set button 39 is pressed again, the traveling speed is set. Then, the tracing stylus 33 is moved along the desired route from the point A to the point B on the topographic map 11. Then, the display unit 37 displays the distance in the real space and the time required for moving at the set traveling speed. When the measurement is completed, the meter 30 is turned off by, for example, pressing the set button 39 twice.

It should be noted that it is convenient to provide a totaling memory when traveling in places where road conditions are different. For example, it is possible to set the highway to run at 100 km / h and the general road to run at 30 km / h, enter each travel section separately, and finally display the total required time. .
