Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traveling body position detecting device for detecting the position of a traveling body traveling on a certain field, and more particularly to a traveling body such as a model horse or automobile on a certain field. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a position detection device for a moving object used in a competition game device in which a car runs and competes.

[0002]

2. Description of the Related Art Conventionally, there are many types of competitive game devices that imitate horse racing, automobile racing, and the like.
As a competition game device that has existed for a long time, a moving object such as a model horse or a model car is run on a circular track to compete for the arrival order or to predict the arrival order. However, in this competitive game, the running object can only be run on the predetermined circular track, and the sense of presence has been reduced and the interest has been reduced by half.

Therefore, the applicant of the present invention has applied for an epoch-making competition game device capable of competing by running on a free course on the field instead of a fixed track like in an actual horse race or automobile race. (JP-A-1-9
No. 4884). According to this competition game device, since a running body such as a model horse can run on a free course on the field, it can run the shortest distance as in an actual horse racing race and disturb the running course of other horses. It is possible to develop a race that makes full use of tactics and other techniques. Therefore, a competitive game device full of a sense of reality can be realized, and has gained widespread support from players.

[0004]

In this competition game device, it is necessary to always detect the position of the running body. However, in order for the running body to smoothly run at a speed equal to or higher than a certain speed, the current position must be set at a predetermined frequency or more. It is necessary to detect the position. Therefore, there is a limit to the number of vehicles that can compete at one time. For example, in order to detect the position of the running body at a frequency of 60 times or more per second, the current competitive game device can drive only about 6 running bodies at a time, and a larger number of running bodies can be run. Could not meet the desire to compete.

An object of the present invention is to provide a position detecting device for a traveling body which can detect the positions of a large number of traveling bodies traveling on a fixed field. Another object of the present invention is to provide a competitive game device using this position detecting device.

With the next trigger pulse, the position of the second model horse 20 is detected by the front detection coil 90 and the rear detection coil 91 of the carrier 40 that moves the second model horse 20, in the same manner as in the case of the first horse. To do. Similarly, 3
The positions of the model horses 20 of the first, fourth, fifth, ... Are sequentially detected.

As described above, according to the present embodiment, the positions of the front detection coil 90 and the rear detection coil 91 of one carrier 40 can be simultaneously measured in one position detection time. More than twice as many horses as in the past can be run at the same time in this race, and a horse racing game that attracts the interest of the player can be realized. The present invention is not limited to the above embodiment, and various modifications are possible.

In the above embodiment, two positions are detected to detect the position of the model horse, but three or more positions may be detected. Further, the position detection method may be another method such as an electrostatic induction method or an ultrasonic method in addition to the electromagnetic induction method of the above embodiment. Further, although the present invention is applied to the horse racing game device in the above-described embodiment, it may be applied to other game devices, and further, the present invention can be applied to position detection of a traveling body such as a robot used in a factory or the like. Needless to say.
