A course 30 imitating a racetrack is provided on an elliptical base 31, and a plurality of racehorse models 32 run on the course 30 to play a game. The base 31 is hollow, and the same number of self-propelled bodies as the racehorse model 32 can run in the hollow part. As will be described later, the self-propelled body has a magnet on the upper surface, attracts a magnet fixed to the lower surface of the racehorse model 32, and when the self-propelled body runs, the racehorse model 32 also moves along with the self-propelled body. To run.

FIG. 6 is a configuration diagram (1) of the racehorse model 32 and the self-propelled body 49 according to the embodiment of the present invention. The self-propelled body 49 runs on the running surface 52 by the front wheel 55 and the rear wheel 53. The direction of the front wheel 55 can be changed by a steering motor 57, and the traveling direction of the self-propelled body 49 can be changed to left or right by a command from a control device (not shown).

Is attached. The filter 110 passes only infrared light of the first wavelength emitted by the infrared light emitting element of the control device, and the infrared light receiving element 61 receives the infrared light of the first wavelength that has passed through the filter 110. Further, the infrared light emitting element 59 is modulated by a signal indicating an abnormality or the like of the self-propelled body 49, emits infrared light having a second wavelength different from the first wavelength, and transmits the light to the control device. Therefore, the drive signal that is the infrared light of the first wavelength and the abnormal signal that is the infrared light of the second wavelength can perform two-way simultaneous communication without causing crosstalk.

The error calculating unit 75 compares the current running position of the self-propelled body 49 with the planned running position from the running table 74, and calculates the error. The error signal is input to the CPU 77 to generate a correction signal for returning the self-propelled body 49 to a predetermined traveling position. The correction signal is converted into a command for driving the steering motor 57 and the drive motor 51 of the self-propelled body 49 by the command creation unit 78, and is emitted from the infrared light emitting element 79 toward the self-propelled body 49. Although the polarization direction of the infrared light emitted from the infrared light emitting element 79 is in all directions,
In the present embodiment, a horizontal polarizer 87 is placed in front of the infrared light emitting element 79, and the infrared light emitted toward the self-propelled body 49 is limited to only horizontally polarized infrared light.

A horizontal polarizer 60 is provided in front of the infrared light receiving element 61 of the self-propelled body 49. The infrared light receiving element 61 of the self-propelled body 49 selects only the horizontally polarized control signal transmitted from the control device 76. And receive. The control command received by the infrared light receiving element 61 is decoded by the command decoder 84. If the control command is a control command for the steering motor 57 or the drive motor 51, a drive command is output to the motor drive unit 85 and the respective motors 51 and 57 are controlled. Drive. On the other hand, if the transmission command is for the transmission coils 50 and 54, the transmission command is output to the oscillating unit 86 and an oscillating current flows through the oscillation coils 50 and 54.

The abnormality detector 83 detects an abnormality of the self-propelled body 49. For example, as described above, when the racehorse model 32 attracted by the magnets 43 and 44 comes off the self-propelled body 49, the microswitch 48 is turned on to detect a horse coming-off abnormality. Further, a motor abnormality or an oscillator abnormality can be detected. The abnormality detection signal from the abnormality detection unit 83 is converted into a code signal by the response creation unit 82, and drives the infrared light emitting element 59.
