An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show a main part of a running body of a horse racing game which is an example of a competitive game machine. In this horse racing game, a model 3 simulating a plurality of racehorses, each of which is mounted on a course board 2, has a running body 1 running on a running surface S by the attraction of the permanent magnets 4, 4. The game is established by following up.

[0007] The traveling body 1 is provided on a traveling surface S by rotating a pair of tires (driving wheels) 7L and 7R individually by a driving device 6 provided in a cover 5 formed in a box shape. It is possible to travel in the direction. The control of the driving device 6 is performed by a control circuit unit 8 provided in front of the driving device 6. The control circuit unit 8 is a circuit mainly composed of a microprocessor, and includes an arithmetic circuit and a storage circuit, and stores a self-scenario received from a controller (not shown) to be described later. Pin 12
The current position of the traveling body 1 is fed back to the controller in response to the information output from the controller, and the traveling of the traveling body 1 is controlled.

A power supply unit 10 is mounted on a support plate 9 provided above the cover 5. Power supply unit 1
In 0, a plurality of power supply pins 11 and a plurality of trace sensor pins 12 are provided. In addition to these, the above-mentioned permanent magnet 4 is attached to the support plate 9.

Support plate 9 supporting power supply unit 10
Is supported by two columns 13, 13 so as to be able to move up and down, and receives an upward urging force by compression coil springs 13a, 13a. Auxiliary wheels 14, 14a are attached to front and rear positions of the power supply unit 10. The posture of the power supply unit 10 with respect to the course plate 2 is supported in parallel. On the support plate 9, the power supply pin 11 and the trace sensor pin 12 are each configured such that the upper end thereof elastically contacts the lower surface of the course plate 2 by an upward urging force applied by a compression coil spring (not shown). The power supply pins 11 and the driving device 6 are connected by a flexible printed cable (FPC) (not shown).

The course plate 2 is composed of a three-layer laminate, the upper layer having a slippery surface and a sheet plate 2a provided with a track-like course, and the middle layer being a reinforcing plate made of a rigid plate material. 2b, and a lower layer is a power supply plate 2c provided with a power supply surface. A power supply pattern (not shown) provided on the power supply surface allows power to be supplied to the drive device 6 from the power supply pin 11 via the above-described FPC when the distal end of the power supply pin 11 makes elastic contact.

A traveling platform 15 for supporting and moving the model body 3 is mounted on the upper surface of the course plate 2. The above-described permanent magnet 4 is embedded in the lower surface of the traveling platform 15, and the model body 3 is attracted to each other by forming a pair with the polarity of the magnetic pole of the permanent magnet 4 on the power supply unit 10. 1 and is movably arranged.

The driving device 6 is mounted on both sides of a mounting plate 16 provided in the center of the lateral width of the cover at a position near the rear of the cover 5 and provided in a partition wall shape (see FIG. 2). A left driving motor 17L for driving the tire 7L on the left side in the traveling direction is mounted on the right side of the mounting plate 16, and a driving gear 18L serving as a starting point of the wheel train G is provided on a driving shaft penetrating the mounting plate 16 and protruding to the left. Is stuck. No. 1 gear 1 on drive gear 18L
9L meshes, and the pinion integral with the first gear 19L meshes with the second gear 20L. Further, the pinion integrated with the second gear 20L is provided with a left tire 7 serving as a left driving wheel.
And meshes with a third gear 21L that rotates integrally with L.

The drive gear 18L is provided with a slit disc 22L which rotates coaxially and integrally therewith. Above the slit disk 22L, when the motor rotates, the slit disk 2
A sensor 23L for detecting the number of 2L slits is provided, and both of them constitute an encoder.

On the other hand, a right drive motor 17R for driving the right tire 7R in the traveling direction is mounted on the left side of the mounting plate 16, and the right wheel train G is mounted on the right side of the mounting plate 16. The right drive motor 17R and the left drive motor 17L are arranged so as not to overlap when projected from the side. When the drive motors 17L or 17R and the drive gears 18L or 18R are arranged on both sides of the mounting plate 16, this is an inevitable configuration because a space for each drive gear 18L and 18R is required. There is an effect that the traveling bodies can approach each other by reducing the width of the body 1, that is, it is possible to travel with the model bodies approaching each other.

In the right wheel train G, a reversing gear 24 for changing the rotation direction of the wheel train G is interposed between the first gear 19R and the second gear 20R. This is because the left and right drive motors 17L, 17L, 17L, 17L, 7L, 7H, 9H, 9H, 9H, 9H, 9H, 9H, 7H, 7H, The number of gears of one wheel train G is increased by an odd number from that of the other so that the left and right tires 7L and 7R rotate in the same direction when the wheels 17R are mounted outward. That is, when the traveling body 1 is run, both drive motors 17L and 17R may be rotated forward or backward by interposing the reverse rotation gear 24 in one of the wheel trains G. The inconvenience due to the difference in characteristics due to rotation can be eliminated (see FIG. 3).

A sensor board 26 is mounted on the lower surface of the cover 5, and a sensor 27 provided on the running surface S for reading a bar code for position detection is mounted thereon. An auxiliary wheel 2 for obtaining stability before and after the traveling of the traveling body 1 is provided before and after the sensor substrate 26 on the lower surface of the cover 5.
8, 28 are provided.

A communication board 29 is mounted on the upper surface of the cover 5 of the traveling body 1. A light emitting element (LED) 30 is mounted on the upper surface of the communication substrate 29, and a photo sensor 31 is mounted on the lower surface. Light emitting element 3
0 and the photo sensor 31 enable two-way communication with a controller (not shown) that creates a game scenario. The traveling body 1 and the controller can communicate with each other by optical communication to control the starting and stopping of the traveling body 1 and the direction and speed of traveling.

[0018]

According to the present invention, the number of gears in one of the pair of wheel trains for connecting the drive motor and the drive wheels is increased by an odd number from that of the other wheel train. Alternatively, the traveling body can be controlled by rotating the drive motors mounted back to back in the same direction of forward rotation or reverse rotation. This eliminates the need to correct the difference in characteristics due to the difference in the rotation direction of the motor, and thus allows the traveling body to travel without impairing the characteristics of the motor, thereby facilitating control of the traveling body.
