In recent years, expressways have been rapidly constructed as toll roads, and automobiles are playing a major role as a means of transporting goods between cities. On many of these toll roads, for example, the usage fee for each vehicle differs depending on the vehicle type as shown in Figure 1, and toll collection stations set up at the entrance or exit of the toll road are charged according to the vehicle type. Fees are being collected. Currently, these vehicle types are determined visually by toll collectors at toll collection stations. Toll collection offices are open day and night, and require a large amount of manpower and expense to distinguish vehicle types and collect tolls.

があるという問題点があつた。 Therefore, if the vehicle type classification can be automatically determined, it will be possible to automatically issue tickets accordingly, resulting in labor savings, and various methods for this automatic determination have already been proposed. For example, Japanese Utility Model Application Publication No. 53-33456 proposes a method of determining the vehicle type by measuring the tread, which is the distance between the centers of both left and right tires, and the number of axles. By the way, as can be seen from the general explanatory diagram of vehicle classification shown in Figure 1, even among three-axle vehicles, there are vehicles classified as ordinary cars and vehicles classified as large cars or extra-large cars. Conventional discriminating devices that only use numbers or the like as a classification principle have had the problem that they may not be able to distinguish the vehicle type classification of these vehicles.
以下、この問題を具体的に説明する。 This problem will be specifically explained below.

ともある。 FIGS. 3a to 3f are explanatory diagrams showing the wheel arrangement (shown only by symbols) and the external appearance of the vehicle body of a three-axle vehicle consisting of a towing vehicle and a trailer instead of a single vehicle body. In the same figure, a is (ordinary car + ordinary car),
In other words, a vehicle equivalent to a towing vehicle, if taken alone, would belong to a regular vehicle, and a vehicle equivalent to a trailer, if taken alone, would belong to a regular vehicle, but if a tow vehicle (regular vehicle) pulls a trailer (regular vehicle). Therefore, the entire vehicle is considered to be one vehicle. The vehicle type classification when the vehicle is considered as one vehicle in this way varies depending on the road administrator, and may be classified as a regular car or a large vehicle.
第3図bもaと全く同じく、(普通車+普通車)

も大型車に区分される。 Figure 3 b is exactly the same as a, (ordinary car + ordinary car)
The vehicle type classification is sometimes classified as a regular car or a large car by the road administrator. c is (normal car + large car), d is also (normal car + large car), e is (large car + normal car), f is (large car + large car), and the car type is any of c to f. It is also classified as a large vehicle.
次に、第2図および第3図における車輪配列の
記号について説明する。 Next, the symbols of the wheel arrangement in FIGS. 2 and 3 will be explained.

In Fig. 2c, the three wheel arrangement symbols shown indicate that any of them can be used, and therefore the explanatory diagrams of the wheel arrangement are also different. The broken line in the same explanatory diagram indicates.
第3図では、車輪配列については、記号のみを
示し、車輪配列の説明図自体を省略してあるが、
これでも前述の記号の説明から車輪配列の具体的
イメージは容易に得られるであろう。 In FIG. 3, only the symbols are shown for the wheel arrangement, and the explanatory diagram of the wheel arrangement itself is omitted.
Even so, a concrete image of the wheel arrangement can be easily obtained from the above explanation of the symbols.

る。 Therefore, in the present invention, we focused on the difference in the shape of the vehicle body between the first and second axes (there is a space S in Figures 2c and d), and the above-mentioned light beam 11 (Figure 4) This is determined by detecting whether it remains disconnected or continues. Specifically, how many times does the light beam 11 pass between the first and second axes of the passing vehicle?
Measure whether it is ON or OFF with counter A, and compare the contents of this counter A with the set value. If it is less than the set value, it is a sightseeing bus (extra large vehicle), and if it is more than the set value, it is a regular freight vehicle (large vehicle). It is determined that

That is, the light beam 11 between the first and second axes of the passing vehicle
Counter A measures the number of ON and OFF times of A, and compares the contents of counter A with the set value. If it is less than the set value, it is treated as the vehicle shown in Figure 2 e, and it is determined to be a regular car. If it is more than the set value, it is The vehicle shown in FIG. 2b is determined to be an oversized vehicle.
