Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply device for a game machine in which a moving body such as a model car or animal receives electric power from the outside and moves within a certain field.

[0002]

2. Description of the Related Art A device for supplying power to a plurality of moving bodies in the above-mentioned game machine has been proposed (actual fair 5-190).
6). In this device, strip electrodes are laid on the upper and lower surfaces of an insulating plate in a direction intersecting with each other, and through holes are provided every other electrode so that adjacent electrodes are alternately the anode and the cathode, and they are electrically connected. By doing so, one strip electrode is provided with a plurality of power supply points. The moving body is designed so that the current collector is always brought into contact with the strip electrode to be supplied with electric power. By adopting such a configuration, when a plurality of moving bodies travel on the same strip electrode at the same time, the moving body farther from the power supply unit (terminal electrode) is supplied with power by the power consumption of the intermediate moving body. It is prevented that the vehicle speed decreases and the vehicle speed is decelerating. That is, even if the current collectors of a plurality of moving objects are concentrated on the same electrode, almost all the current collectors are almost unaffected by the difference in distance, and substantially the same power is always supplied from the power supply point, enabling fair race development. I have to.

However, although this device has a plurality of power supply points, a common power distribution route is formed without forming an individual power distribution route from the power supply unit to a plurality of moving bodies. The power consumption on this common power distribution route is determined by the electrical resistance of the route. This is a structure in which a strip-shaped electrode on one side and a strip-shaped electrode on the other side are connected by a through hole, and a plurality of these connecting paths are connected side by side. When traveling on the strip electrode, substantially the same electric power is always supplied from the electric power supply point, but actually there is still a considerable difference in the electric power supplied to each moving body.

Further, in the above device, the contact of the current collector to the strip electrode is urged toward the strip electrode by the spring so as to maintain the contact even if the power supply plate has some irregularities. Since the strip electrode and the current collector are caused to slide with each other, the contact resistance fluctuates greatly and the supply voltage to the moving body becomes unstable, so that the moving body cannot travel smoothly. In order to alleviate this, by arranging multiple current collectors and keeping some current collectors in contact at all times, even if there is a current collector for which sufficient contact could not be obtained, one of the current collectors will make up for it. ing.

[0005]

However, if the total number of current collectors is increased in order to increase the number of current collectors that are constantly in contact with each other, the number of current collectors that do not function instantaneously increases, resulting in poor efficiency. The mechanical resistance due to the biasing pressure corresponding to the total number of current collectors increases rather, and the moving body cannot run smoothly. The object of the present invention is to solve the above problems,
The power feeding plate has an alternating multi-stage laminated structure of insulating plates and conductive layers, and at least one of the laminated conductive layers corresponds to an anode current distributor and at least another one corresponds to a cathode current distributor, and a minimum total number of current collectors is required. By increasing the number of current collectors that are always in contact with the anode and cathode as much as possible, the power supply to each mobile unit is stabilized regardless of the position of the mobile unit, and each mobile unit can obtain the same power and move the mobile unit. An object of the present invention is to provide a power supply device for a moving body, which has a low mechanical resistance as much as possible and enables smooth traveling.

[0006]

In order to achieve the above object, a power supply device for a moving body according to the present invention supplies power to a moving body that freely moves in a field of a game machine, so that it can be moved upward or downward in the field. And a power supply plate having a strip-shaped electrode formed on the surface layer so as to be alternately connected to a power source so as to serve as an anode and a cathode, and mounted on each moving body, and a large number of current collectors are attached as the moving body moves.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to the drawings. FIG. 1 is an external perspective view of a game machine to which a power supply device for a moving body according to the present invention is applied. This example is a car racing game, a horse racing game, a boat racing game, and the like, in which a plurality of model bodies 2 such as automobiles freely run on an annular track to play a game. A plurality of terminals 3 are arranged around the annular track, and a monitor 7, an operation panel 4, a coin insertion slot 5, and a coin payout slot 6 are attached to the terminal 3. Model body 2 that is expected to win a prize by inserting coins and operating the operation panel 4
You can play the game by voting for.

FIG. 2 is a side view of a moving body provided with the power feeding device according to the present invention. A moving body 44 exists below the model body 2 via a track. The model body 2 and the moving body 44 are respectively provided with magnets 25 at positions in which they are attracted to each other and are separated from the track by a slight distance. Has been done. The model body 2 itself has no power source, but the front wheels have one or more casters (or spherical wheels) 15, and the rear wheels have independent wheels 12 on the left and right, respectively. It follows the direction smoothly. The truck has a three-layer structure in which an upper layer is a game field 8 made of cloth, a middle layer is a reinforcing plate 22 made of resin, and a lower layer is a power supply plate 11 according to the present invention.

A traveling path 23 is laid under the power supply plate 11 via a space in which the moving body 44 travels. Below the traveling path 23, there are fixed intervals in the front, rear, left and right directions, or XY at equal angles at corners. A position transmitting plate 21 is provided on which a transmitter 20 for transmitting the coordinate position is installed. Further, a reinforcing material 24 is laid further below via a spacer. The moving body 44 includes two steering / driving motors 17, an infrared communication means (not shown), a position detector, a controller, a motor driver, etc., and one or more casters (or spherical wheels) 15, 19 in front of the moving body 44. Two sets of traveling means constituted by independent wheels 13 and 18 are provided on the left and right sides respectively.

The two sets of traveling means are arranged in the direction in which the wheels come into contact with the ceiling surface and the floor surface, respectively, and the parallel links 16 having compression elasticity by the torsion springs 26 are provided therebetween. As a result, the traveling space of the moving body is pressed in the vertical direction, and vibration in the front-back direction of the moving body is suppressed
You can run smoothly. Further, the lower rear wheel 18 is driven by being gear-coupled to the steering / driving motor 17, but the two motors respectively drive left and right wheels,
It is possible to freely steer by changing this rotation ratio. A current collector 9 having a plurality of current collectors 10 according to the present invention arranged in a direction protruding upward is fixed to a wheel fixing member of the upper traveling means, and a belt-shaped electrode on a power supply plate 11 comes into contact with the current collector 9 to move the same. Power is supplied to the body 44.

Regarding the traveling control of the moving body 44, the game machine body uses the infrared communication means to collect a set of coordinate data (that is,
After a few minutes, the speed and course data indicating that the vehicle must have arrived at the X and Y coordinates are transmitted to the mobile unit 44. The moving body 44 drives the steering / driving motor 17 based on this received signal, but detects the transmission signal of the transmitter 20 on the traveling path 23 via the position detector and feeds this back to the control device. Is driving a predetermined course at a predetermined speed.

FIG. 3A is a sectional view showing an embodiment of the laminated structure of the power feeding plate, and FIG. 3B is a sectional view taken along the line AA '. This example is realized by a manufacturing process of a four-layer board, and three layers of insulating plates 37 and 4 are formed so that the conductive layer becomes a skin layer.
The conductive layers are alternately stacked. A cathode terminal electrode 34 and an anode terminal electrode 35 for connection with a power source are arranged on one surface of the skin conductive layer at positions where the electric wire can be easily drawn out, and on the other surface, a strip electrode (anode) 33 having a width W and a strip shape are formed. Electrodes (cathodes) 36 are arranged in parallel at intervals t. The feeding plate 11 is provided at predetermined positions of the strip electrode (anode) 33, the strip electrode (cathode) 36, the cathode terminal electrode 34, and the anode terminal electrode 35.
A plurality of holes 32 penetrating through are provided.

The through hole 32 is generally called a via hole, and a conductor 38 is formed on the inner wall of the hole having an extremely small diameter, and the space between the strip electrode (anode) 33 and the anode terminal electrode 35 and the strip electrode (cathode). 36 and the cathode terminal electrode 34 are electrically connected to each other. Since the diameter of the contact surface of the current collector 10 is larger than the inner diameter of the through hole 32, the current collector 10 can smoothly pass through the through hole 32 against sliding. The inner conductive layer is an inner layer which is not connected so that adjacent electrodes of the strip electrodes are alternately connected to different polar layers by the through holes 32, and the cathode terminal electrode 34 and the anode terminal electrode 35 are connected to different polar layers. Gap 30a, 31a for insulation is provided in the through hole portion of the conductive layer. Therefore, one of the inner conductive layers becomes the cathode current distributor 31 and the other becomes the anode current distributor 30, and adjacent strip electrodes (cathodes) 36 and strip electrodes (anode) 33 should be arranged alternately. become.

In the example of FIG. 3, the through hole for connecting to the terminal electrode also serves as the through hole for connecting to the strip electrode, but different through holes may be used. Although this example shows the case where there is one through hole for connecting to the terminal electrode, a plurality of through holes may be provided. Although the terminal electrode is provided on the surface different from the strip electrode, the electric wire may be directly connected to the strip electrode. When arranging multiple power supply plates side by side in the field, when the size from the edge of the power supply plate to the strip electrode is (1/2) t, when the multiple power supply plates are connected, the space that can be connected is set. can be t. Similarly, when a plurality of power supply plates are installed side by side and the power supply plate installed at a place such as the corner of FIG. 1 is divided into a plurality of power supply plates,
By using the two surface layers of the power feed plate as the strip electrodes, and by arranging the strip electrodes on one side in the perspective direction to look at the other strip electrode in the same arrangement, two power feed plates are used. By inverting one sheet and arranging the strip electrodes linearly at symmetrical positions, one power feeding plate can also serve as two power feeding plates.

Further, the layer thickness and the number of layers of the power distribution body can be changed as required. Even if there is some warpage or distortion in the power supply plate, contact with the strip electrode can be maintained due to the biasing force of the current collector, but the warpage and distortion will be severe (current collector that is determined by durability as well as severe warpage and distortion). In order to maintain contact even if the head is worn, the current collector movement stroke is enormous, so if this stroke is set to an appropriate value), contact cannot be maintained. Therefore,
Since the power supply may be cut off, the power supply plate should be kept as flat as possible. However, according to the present invention, since two or more conductive layers without breaks are laminated, it is possible to prevent warpage and distortion due to a temperature difference and to have high rigidity, so that it can be used as it is as a ceiling surface or a floor surface.

FIG. 4 is a side view showing the structure of the current collector. The current collector 10 has a columnar shape with a tip 10a having a hemispherical shape, and flanges 10b and 10c are formed on an upper portion and a lower portion. A compression spring 41 is interposed between the upper flange 10b and the current collector support 40, and the tip 10a of the current collector is brought into contact with the power supply plate 11 at an appropriate pressure. As a result, even if the power supply plate 11 has some irregularities, the contact is always maintained, a small contact resistance is realized, and stable power is supplied to the moving body. The lower flange 10c serves as a stopper.

Generally, the strip electrode needs a cross-sectional area through which a necessary current can flow, and a step between the strip electrode and the inter-electrode gap occurs to some extent. In addition, since the maximum size of one power supply plate is limited due to processing, a plurality of power supply plates may be connected to each other to form one field, and this joint step may be formed to some extent. Therefore, when the moving body travels and climbs over these steps, the urging pressure of the current collectors easily catches one or two current collectors. However, since the power is mainly supplied to the strip electrodes from the anode power distributor and the cathode power distributor by the structure of the power feeding plate, the thickness of the strip electrodes can be reduced. In addition to that, increase the number of current collectors that are always in contact with the minimum required number of current collectors, as described below, so that the energizing pressure of each current collector is sufficient to obtain a sufficient total contact resistance. Since the number is reduced, it is possible to prevent the collector from being caught.

FIG. 5 is a diagram for explaining a contact state between the strip-shaped electrode of the power feeding plate and the current collector. As shown in FIG. 5, in the current collector, the current collector 10 is arranged at the apex position or the apex position and the center position of a regular polygon having a predetermined diameter. Even when the vehicle travels, a predetermined number or more of the current collectors 10 are always in contact with the strip electrodes 33 and 36 with the required minimum number of current collectors. The predetermined diameter is W, the width of the strip electrodes is t, the gap between the strip electrodes is t, the dimension from a straight line connecting a plurality of current collectors to an arbitrary current collector orthogonal thereto is X _n, and m is a predetermined value. Assuming the number of strip electrodes included in the diameter of m is m (W + t) -t
When <X _n <m (W + t) + t ... (A), the current collector is located on one gap between the strip electrodes and cannot be fed.
It is determined by arranging the current collector at a position other than the formula (A). However, this does not apply if another current collector can come into contact even if this condition is not satisfied.

In order to satisfy the condition that a predetermined number or more of current collectors come into contact with the anode and cathode of the strip electrode, and to configure this condition with the minimum necessary total number of current collectors, X _n > 2W + 3t. Under the condition (2), the power can be supplied, but since W> _Xn is not satisfied at the vertex position of the regular polygon having the minimum number of angles, it is out of the condition. That is, m = 3 or more is out of the condition. Therefore, substituting m = 1, 2 into the equation (A),

[Equation 1] W <X _n <W + 2t ... (A) ′ 2W + t <X _n <2W + 3t ... (A) ”, and the positions other than the positions where the expressions (A) ′ and (A)” are satisfied are as follows. It becomes an expression. _Xn <W, W + 2t < _Xn <2W + t (B) The relationship at this time is shown in FIG.

However, the following conditions must be satisfied. Condition (i) The minimum number of current collectors must be equal to or greater than the number of constant contacts of both poles + the number of current collectors aligned on the gap. Condition (ii) X _n (X _n <W) less than the W value is defined as X _a, and this X _a is calculated from the number of current collectors falling in the gap between the charges It is a dimension between the current collectors in contact with the current collector until reaching a predetermined number, and is determined by the maximum size of X _n . X _n (W + 2t <more than (W + 2t)
X _n ) is defined as X _b, and X _n (X _n ) of (2W + t) or less is defined.
<2W + t) is defined as X _c . Condition (iii) When the predetermined number of current collectors that are in constant contact with each strip electrode is an odd number, one current collector is added at the center position. Condition (iv) Except when other current collectors can come into contact when the above formula (B) is not satisfied.

FIG. 7 is a diagram showing an example of a concrete calculation result. FIGS. 7A and 7B are examples in which at least two current collectors are always in contact with the anode strip electrode and the cathode strip electrode, respectively. Assuming that the width of the strip electrodes is W = 8 mm and the interval between the electrodes is t = 1 mm, the minimum angle (two collectors) is obtained when the current collector is arranged at the vertex position of the regular hexagon as shown in FIG. If the electrons fall into the gap, it is necessary to have two current collectors in contact with each of the anode strip electrode and cathode strip electrode, which is 2 + 4 = hexagonal), and the diameter connecting these vertex positions is calculated by the following formula. You can ask.

[Formula 2] X _a <W (1) X _b > W + 2t (2) X _c <2W + t (3) If the diameter of the circle forming the regular hexagon is φ, then the formula (1) becomes (φ / 2) × 2 sin {360 / (6 × 2)} <8 ∴φ <16 Equation (2) is (φ / 2) × [1 + sin {360 / (6 × 2)}] ＞ 8 + 2 ∴φ> 13. 3 Formula (3) is φ <2 × 8 + 1 ∴φ <17 Therefore, the diameter connecting the vertices of a regular hexagon is 13.3 mm.
It should be <φ <16 mm. In such a case, if the distance between the electrodes is 2 mm instead of t = 1 mm, 16 mm
<Φ <16 mm, the answers are inconsistent, and the diameter that satisfies the above formula cannot be obtained, and in this case, it is ignored.

Next, when the width of the strip electrodes is W = 8 mm and the interval between the electrodes is t = 2 mm, when the current collector is arranged at the vertex position of the regular heptagon as shown in FIG. 7B. Is the minimum angle (when W = 8 mm and t = 2 mm in Fig. 7 (a), the answer is inconsistent, so a regular hexagon does not hold, and a hexagon with one more angle is the minimum angle) Therefore, the diameter connecting the vertex positions can be calculated by the following formula.

[Formula 3] X _a <W (4) X _b > W + 2t (5) X _c <2W + t (6) If the diameter of the circle forming the regular heptagon is φ, then equation (4) becomes (φ / 2) × [cos (360/7) ＋ cos {(360 × 1.5) / 7}] <8 ∴φ <18.9 (5) is (φ / 2) × {1 + cos (360/7)} > 8 + 4 ∴φ> 14.8 Equation (6) is (φ / 2) × [1 + cos {360 / (7 × 2)}] <2 × 8 + 2 ∴φ <18.9 Therefore, the diameter connecting the vertex positions Is 14.8 mm <
It should be φ <18.9 mm.

FIGS. 7C and 7D are examples in which at least three or more current collectors are always in contact with the anode and the cathode, respectively. The width of the strip electrodes is W = 8 mm, and the distance between the electrodes is t = 1.
mm, the minimum number of angles when the current collectors are arranged at the vertex position and the center position of the regular octagon as shown in FIG. If there are current collectors and they fall into the gap like the regular hexagon including the center position, it is necessary to have three current collectors each contacting the anode strip electrode and the cathode strip electrode, which results in 2+
6 = octagon), and the diameter connecting the vertex positions can be obtained by the following calculation formula.

[Formula 4] X _a <W (7) X _b > W + 2t (8) X _c <2W + t (9) Here, X _c = 2X _a , and the condition of X _c <2 W holds, so X _c <2W + t ... (9) is never calculated.
If the diameter of the circle forming the regular octagon is φ, then (7) is (φ / 2) <8 ∴φ <16 (8) is (φ / 2) × 2 sin (360/8)> 8 + 2 ∴φ <14.1 Therefore, the diameter connecting the apex positions is 14.1mm <
It should be φ <16 mm. In this case, if the distance between the electrodes is 2 mm instead of t = 1 mm, then 17 mm <
Since φ <16 mm, the answers are inconsistent, and the diameter satisfying the above formula cannot be obtained. In this case, it is ignored.

Next, when the width of the strip electrodes is W = 8 mm and the distance between the electrodes is t = 2 mm, current collectors are collected at the apex position and the center position of the regular hexagon as shown in FIG. 7 (d). The minimum number of angles when placed (W = 8 mm, t = 2 m in FIG. 7 (c))
If m, the answer is inconsistent, so a regular octagon does not hold, and a polygon with a large number of ones becomes the minimum number of angles), and the diameter connecting this vertex position should be calculated by the following formula. You can

[Formula 5] X _a <W (10) X _b > W + 2t (11) X _c <2W + t (12) If the diameter of the circle forming the regular hexagon is φ, then equation (10) becomes (φ / 2) × cos {360 / (9 + 2)} <8 ∴φ <17 (11) The formula is (φ / 2) × [1+ cos {(360 × 1.5) / 9}] ＞ 8 + 4 ∴φ> 16 (12) The formula is (φ / 2) × [1 + cos {360 / (9 × 2)}] <2 × 8 + 2 ∴φ <18.5. The example of FIG. 7D corresponds to the formula (A) '. As an example, even if the dimension of C is W ≦ C ≦ W + 2t, there is no problem because the current collector of one strip electrode contacts the current collector of << 10 >> to the other strip electrode. Even if the dimension of D is W ≦ D ≦ W + 2t, there is no problem because the current collector of one strip electrode contacts the current collector of <10> to the other strip electrode. This is an example corresponding to the condition (iv), and in the case of the current collection for the current collection of and the current collection for the current collection of, the application of the formula (B) is excluded. Therefore, the diameter connecting the vertex positions is 16mm <φ <17mm
Is fine. The << symbol in << 10 >> above means ○.

Next, the equation (B) and the conditions (i) (ii) (iii) (i
According to v), X _a , in FIGS. 7 (a) (b) (c) (d),
A method of determining _Xb and _Xc will be described. Figure 7
Considering X _n <W in (a), this equation is
It corresponds to the preceding stage of (ii). In the preceding stage of condition (ii), when the current collector of, for example, falls into the gap, the most current collector falls in the gap, and the current collectors that contact two are current collectors of (and may be) The maximum size current collector from the electron is (and becomes). Therefore, X _a is the distance connecting and. Similarly for FIGS. 7B, 7C and 7D, X _a
Is determined. In the case of FIG. 7B, for example, 2
When two current collectors fall, for example, FIG. 7 (c) shows three current collectors fall, and FIG. 7 (d) shows two current collectors fall, for example. That is the case.

In the middle stage of condition (ii) in FIG. 7A, when (W + 2t) or more, X _n is defined as X _b, and X _n is W.
If it is larger than X _b , the distance of X _b
If (W + 2t) or more, the number of current collectors that are always in contact with each strip electrode is 2 or more. Therefore, X _b is the distance of. 7 (b), (c) and (d) are similarly determined. In the latter part of condition (ii) in FIG.
W + t) or less when X _n is defined as X _c, if X _n is greater than W, if put the distance between X _c, always in contact with the respective strip electrodes if X _c is (2W + t) or less There are more than two current collectors. Therefore, X _c is the distance of. 7 (b), (c) and (d) are similarly determined.

FIG. 8 is a diagram showing a connection structure between the current collector and the moving body electrode terminal. The output of each collector is connected to two diodes whose current directions are opposite,
The output lines of the diodes in the positive direction are combined into one, and the output lines of the diodes in the opposite direction are combined into one to form the cathode, and electric power is supplied to the moving body side. Since they are connected in this way, the polarity does not change even if the moving body moves and the strip electrode in contact with the current collector changes, and the positive potential is always on the anode side of the moving body and the negative potential is on the cathode side. Are connected. Each diode also has a function of preventing a short circuit between the anode and the cathode on the power supply plate. Further, since this diode circuit is a rectifier, the voltage supplied to the power supply plate may be either DC or AC.

[0029]

As described above, according to the present invention, unlike the conventional example, the power feeding plate is constructed by alternately laminating the insulating plates and the conductive layers, and at least one of the conductive layers is used as the anode current distributor. At least one other is used as a cathode distributor, and power is supplied to the strip electrodes via these, so that the electric resistance in the distribution route is reduced, and unnecessary power consumption in the distribution route can be reduced. , It is possible to make the power supply to each mobile body substantially equal. For example, in the case of the minimum laminated structure, that is, when the anode distributor and the cathode distributor are occupied by one surface, the electrical resistance can be suppressed to about 1/3 of that of the conventional example. In addition, since the power is supplied mainly by the anode and cathode distributors, the thickness of the strip electrodes can be made thin, so that the step difference over the current collector can be reduced and the sliding resistance of the collector can be reduced. Can be run smoothly.

Further, when a plurality of power feed plates are arranged side by side in a field and the power feed plate at the semicircular corner portion is divided into a plurality of parts, the conductive layer is made into four layers or more, and the front and back surface layers are formed. If the strip-shaped electrode is used as the strip-shaped electrode and the shape of the other strip-shaped electrode viewed from the perspective direction on the side of one strip-shaped electrode is the same, two sheets of one type of power supply plate are used and one of them is turned over to the target position. It is possible to arrange the power supply plates, and it is possible to use common parts for the power supply plate, which has the effects of reducing costs and facilitating component management. In addition, since it has a multi-layer structure, it has less warpage and distortion than the conventional example, and has increased rigidity, which can contribute to stable power supply to the moving body.

In the present invention, the current collector is provided at the apex position or the apex position and the central position of the regular polygon where the current collecting conditions are the same regardless of the posture of the moving body, and the most severe condition, that is, a plurality of current collecting devices is provided. Even if power is not supplied due to the fact that there is one gap between the strip electrodes, each of the anode and cathode of the strip electrodes comes into contact with a predetermined number or more of current collectors, and this condition can be realized with the minimum necessary total number of current collectors. Since it is configured, the following effects can be obtained. That is, since the number of current collectors that are constantly in contact can be increased with the minimum required number of current collectors, sufficient contact can be obtained, and the power supply to the moving body can be stabilized in combination with the power supply plate having the multi-layer structure. .

Then, the moving body travels and one or two current collectors are easily caught at the step over the strip electrodes or the joint step between the feed plates, but the strip electrodes on the feed plate are made thin as described above. Therefore, the resistance to jump over the step is reduced, and the biasing pressure of each current collector can be reduced to the extent that a sufficient contact resistance can be obtained overall, so that the current collection is less likely to be caught. It is possible to smoothly move the moving body, suppress abrasion of the current collector, and improve durability. Also,
Increase the number of current collectors that are in constant contact with the minimum number of current collectors,
Since sufficient contact is obtained, the period for cleaning the power supply plate can be extended and maintenance is simplified.
