BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power feeding mechanism for a self-propelled body of a race game device by a self-propelled body, in a matrix form provided on a two-dimensional traveling plane or ceiling surface on which the self-propelled body travels. Or, about the power feeding mechanism that feeds the self-propelled body through the multiple power receiving terminals of the self-propelled body from the power supply plate that has the positive electrode and the negative electrode in a stripe shape, a minute electric leakage (short circuit) between the positive electrode and the negative electrode. It is possible to prevent the accident due to the electric leakage by detecting the electric shock.

2. Description of the Related Art There are various types of race game devices using self-propelled bodies, but typically, the self-propelled body is a model body and self-propelled from the power supply plate provided on the traveling surface thereof. One that feeds power to a self-propelled body through a large number of power receiving terminals provided on the body (Japanese Utility Model Laid-Open No. 61-171993), a self-propelled model body that runs on the upper running surface runs on the lower running surface via magnetic force. In the one guided by the body (race game device with a two-story structure),
One in which a power supply plate is provided on the lower surface of the upper traveling surface (ceiling of the traveling space of the self-propelled body) (JP-A-9-122352), and one in which a power supply plate is provided on the traveling surface of the self-propelled body (JP-A-11-24445).
No. 17). The structure of the power feeding plate includes a structure in which positive electrodes and negative electrodes are arranged in a matrix, and a structure in which they are arranged in stripes, one example of which is as shown in FIG. This power supply plate 1 includes a strip-shaped or wide linear plus electrode 11a and a minus electrode 11a.
b and densely and alternately arranged. Five power receiving terminals 20a to 20e are provided on the lower surface of the self-propelled body 10, and one of the power receiving terminals always contacts the plus electrode 11a or the minus electrode 11b, and these power receiving terminals are connected via the electric circuit shown in FIG. 2, for example. The self-propelled body is powered from the power receiving terminal. In the electric circuit of FIG. 2, a pair of diodes 21a to 21e and 22a to 22e having different energizing directions are respectively interposed between wirings x and y between each power receiving terminal and the load 25, and the wirings x and A capacitor 23 is interposed between y and a power switch 24 is interposed on the wiring y.

As described above, the distance between the electrodes arranged in stripes or in a matrix is very small. Therefore, if dust or the like adheres to the gaps between the electrodes, a short circuit may occur between the electrodes via the dust. become. While the leakage (short circuit) due to dust etc. is extremely small, there is no particular damage to the power supply plate, but if this leakage current gradually increases, smoke will start to be generated and burn out locally. There is. In order to prevent this, conventionally, measures have been taken such as detecting an excess current of the power supply plate and interrupting the current of the power supply plate with a breaker (interrupting device).

By the way, since the number of self-propelled bodies simultaneously running in the race game device is different, the regular maximum current consumption is not constant, and the running state of the self-propelled body (for example, at the start,
Since the current consumption fluctuates depending on acceleration, etc., the normal maximum current consumption is not constant in this sense as well. For this,
The reference current of the breaker is set to be considerably higher than the current value during normal traveling. However, since the current of the power supply plate exceeds the set value of the breaker, the power supply plate will not be burnt out, and even with a relatively weak leakage (short) current,
As it continues to flow for a long time, it gradually heats up and eventually smoke comes out. Therefore, since the safety device using the breaker does not react to the relatively weak leakage current, the above burnout cannot be avoided. Japanese Unexamined Patent Application Publication No. 9-122352 (running without a track), Japanese Unexamined Patent Application Publication No. 11
In the self-propelled body that travels on the lower traveling surface and guides the model body that travels on the upper traveling surface via a magnet, as described in Japanese Patent Publication No. 244517 (line guidance traveling), the lower traveling Since the power supply current to the self-propelled body is relatively large (there is an electromagnet for induction, the running resistance of the self-propelled body is large, and therefore the rated current is large), the power supply plate burnout accident due to the above-mentioned leakage. Is likely to occur, and since the space provided with the power supply plate is a closed space, it is not possible to detect smoke from the power supply plate at an early stage.

Therefore, the above-mentioned leakage of the power supply plate
The early detection of (g) is a particularly important problem in a racing game device having a two-story structure, and in order to avoid this problem, it is important to detect a small leakage current during running at an early stage.

SUMMARY OF THE INVENTION The present invention relates to a two-story racing game device in which a model body traveling on an upper traveling surface is guided by a self-propelled body traveling on a lower traveling surface via magnetic force, so to speak, plus a power supply plate. The problem is to devise a safety mechanism so that a relatively weak leakage current due to a short circuit between the electrodes and the negative electrode can be found early and reliably.

[Measures taken to solve the problem]

[Means for solving the problem] [Means for solving the above problem]
A power feeding mechanism to a self-propelled body of a racing game device in which a model body traveling on the upper stage traveling surface is guided by a self-propelled body traveling on the lower stage traveling surface through magnetic force by a power supply plate and a large number of power supply terminals of the self-propelling body. Assuming that, the following (a) to (f) are included. (A) The self-propelled body current detection means for detecting the current consumption of each self-propelled body is provided in the self-propelled body, and (b) the current value detected by the current detection means is transmitted to the control device of the game machine body. Each individual self-propelled body is provided with a current value transmission means for
(C) The game machine main body is provided with a current adding means for adding the current consumption value transmitted from the self-propelled body current detecting means,
(D) The power supply plate current detection means for supplying power to the power supply plate is provided in the main body of the game machine. (E) The current addition value by the current addition means is compared with the current detection value by the power supply plate current detection means by a comparator. However, it has a current excess time measuring means for measuring the current excess time when the power supply plate current detection value exceeds the current addition value by a predetermined value or more, and (f) the current measured by the current excess time measuring means. A breaker shall be provided to cut off the power supply to the power supply plate when the excess time exceeds the specified time.

[0007]

[Function] Since a part of the current supplied to the power supply plate is consumed also by the electric resistance of the contact surface between the power receiving plate of the self-propelled body from the power supply plate and the power supply plate, power is supplied to each self-propelled body. The power supply current value to the power supply plate is larger than the added current value obtained by simply adding the consumed currents, although it is minute. Since this is the difference between the integrated value of the current consumption value of the self-propelled body in the normal state and the value of the power supply current to the power supply plate, it can be actually measured for each individual game device. This is the above "predetermined value".
When the difference between the added current value detected by the current adding means and the current detection value of the power feeding plate exceeds the predetermined value, the excess is considered to be an excess current due to a short circuit of the power feeding plate or the like. Therefore, it is possible to early and surely discover that there is a small excess current. The flow of the excess current for a moment can occur due to a sudden change in the running state of the self-propelled body, and this is not particularly abnormal. When this excess current is continuously measured for a predetermined period of time or longer, it is determined that there is an excess current due to a leakage (short circuit) of the power supply plate, and the power supply to the power supply plate is cut off by the breaker. While allowing a normal momentary excess current, it is possible to reliably detect an excess current due to a short circuit of the power supply plate. Therefore, before the smoke is generated from the short-circuited part due to dust adhesion, etc., 2 It is possible to detect abnormal current leakage from a power supply plate in a story racing game machine early and surely, and to automatically detect the danger caused thereby.

[0008]

Embodiment 1 Embodiment 1 is that the predetermined time is set to 2 seconds. By setting the predetermined time to 2 seconds, it is possible to ensure the safety while suppressing the emergency stop of the game due to the occurrence of excess current to a necessary limit.

[0009]

[Means for solving the problem] Means 2 taken for solving the above problems are
A power supply plate provided on the running surface or ceiling surface of a racing game device that guides a model running on the upper running surface via a magnetic force with a self-running body running on the lower running surface, and self-running It is configured by the following (a), (b), and (c) on the premise of a power supply mechanism with a large number of power supply terminals of the body. (B) Each individual self-propelled body has a power cutoff switch,
(B) A power supply plate current detecting means for supplying power to the power supply plate is provided in the game machine main body, and (c) a current by the power supply plate current detecting means in a state in which the power supply cutoff switches of all the self-propelled bodies are turned off. A disconnection device shall be provided to interrupt the power supply to the power supply plate when the detected value is above a specified value.

[0010]

When the race game device is initially installed, the power supply to each self-propelled body is completely cut off, and the power supply current to the power supply plate in this state is measured and set as the initial value. This is the above "predetermined value". And regularly during the service period,
Cut off all the power supply to each self-propelled body and measure the power supply current to the power supply board in that state. When the power supply current to the power supply plate during this shared period exceeds the initial value, it is considered that there is some leakage from the power supply plate. When there is some leakage from the power supply plate, the breaker is immediately actuated to cut off the power supply to the power supply plate. Therefore, the risk of short circuiting the power supply plate is avoided.

[0011]

First Embodiment A first embodiment is a concrete example of the solving means 1. The current supplied to the load 25 of each self-propelled body 10 is measured by the current detection means 1A provided in the wiring x, and this current value is transmitted to the current adder 31 of the game machine body. At the same time, the current to the power feeding plate 1 is measured by the power feeding plate current detecting means 1A, and the detected value of the power feeding plate current and the added value added by the current adder 31 are compared by the comparator 3
Compare with 2. The difference between the two current values and the permissible reference value (the initial value at the beginning of the race game device installation, that is, the power supply plate current detection value when the power switch 24 of all the self-propelled bodies is turned off at the beginning of the race game device installation) The comparator 3
3, and when the difference is larger than the initial value, the comparator 3
An output signal is output from 3. Then, the time during which the output signal from the comparator 33 continues is determined by the current excess time measuring means 33.
And the measured time exceeds the allowable time (eg 0.5
Second), the current excess time measuring means 34 outputs,
By this output, the power supply to the power supply plate is interrupted by the interruption device 1B. It should be noted that there is no particular inconvenience even if the cutoff device 1B is activated immediately when the above difference exceeds the initial value.
In that case, the allowable excess time can be set to 0 seconds, or the current excess time measuring means 34 can be omitted.

[0012]

Second Embodiment A second embodiment is a concrete example of the solving means 2.
In this embodiment, the current detecting means 30 of the self-propelled body, the current adder 31 and the like are unnecessary, and the micro-leakage is caused only by the power feeding plate with reference to the initial value of the power feeding plate when the race game device was initially installed. Is to be detected early. At the beginning of the installation of the race game device, the current detection means 1A measures the current value to the power supply plate with the power supply switches 24 (see FIG. 2) of the power receiving circuits of all the self-propelled bodies shut off, Use the initial value (reference value). This reference value is zero if there is no equipment powered from the power supply plate. During the subsequent service period, the power supply switches 24 of all the self-propelled bodies are periodically turned off, and in that state, the current value to the power supply plate is measured by the current detection means 1A. When the measured value is larger than the reference value, the breaker 1B is turned off to cut off the power supply to the power supply plate regardless of the difference.

The above example is for a power supply mechanism having a power supply plate having stripe electrodes on the traveling surface, but the same applies to a power supply mechanism having a power supply plate having matrix electrodes. The same applies when the power feed plate is provided on the ceiling. Also, regarding the electric circuit of the power feeding mechanism, an example in which the principle is easy to understand is shown,
The power switch 2 may be used as long as it has the same function.
4. The same applies to the current detecting means 30.

[0014]

As described above, while the game device is operating,
Since the game device is stopped by easily and surely detecting a minute electric leakage of the power supply plate due to dust or the like, the game device cannot be restarted unless maintenance of the power supply plate is performed. Therefore, it is ensured that the maintenance will be carried out when there is a slight electric leakage from the power supply plate. Therefore, for a two-story race game device in which the maintenance of the power supply plate is apt to be neglected, the maintenance of the power supply plate can be surely carried out when necessary, and dust of the power supply plate causes the maintenance of the power supply plate. Trouble due to the continuation of a relatively small electric leakage caused by short-circuiting between the electrodes is surely prevented.
