Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a variable winning device that is mounted on a game board of a ball game machine and changes between a state in which a game ball is easily received and a state in which it is difficult to receive a game ball.
[0002]
[Prior art]
The variable prize device installed in the game board of the ball game machine is in a closed state in which it is difficult to accept a game ball when a pair of opening and closing members are brought close to each other, and an open state in which a game ball is easily received when the opening and closing members are separated from each other. The variable winning device (tulip type variable winning device) or a single opening / closing plate is closed, the entrance (winning port) is blocked, and when the opening / closing plate is tilted so as to protrude to the front side, along the surface of the game board There is a variable prize winning device called an attacker having a structure in which a falling game ball is guided to an entrance by an opening / closing plate.
[0003]
[Problems to be solved by the invention]
In the conventional variable prize winning device, a solenoid is used as a drive source for driving the opening / closing member, and a mechanism for converting the reciprocating motion by the solenoid into the swinging motion (rotating motion) of the opening / closing member is required. For this reason, the structure is complicated and downsizing is difficult.
[0004]
It is an object of the present invention to simplify the structure of the variable winning device and further reduce the size.
[0005]
[Means for Solving the Problems and Effects of the Invention]
The variable prize winning device according to claim 1 for solving the above-mentioned problem is as follows.
A winning device that is equipped on a game board of a ball game machine and receives a game ball,
A receiving port that receives a game ball from the front side of the game board and passes it to the back side of the game board, and a swinging shaft that is substantially parallel to each other are arranged facing each other, and swings above the swinging shaft. A pair of opening and closing members that swing between a closed position in which the axial portions are close to each other and an open position in which the axial portions are spaced apart from each other; In the variable winning device that makes it easier to receive the game ball in the receiving port than when the member is in the closed position,
When the opening / closing member is in the open position, the game ball that has entered between the opening / closing members from above is projected in a series with the bottom plate of the guide rod connected to the back side of the receiving port. A guide plate leading to the receiving port;
A lower plate is connected to the substrate on which the receiving port is provided by a connecting plate and is arranged in parallel with the substrate, and a front plate that supports the swing shaft with the substrate,
An electromagnet fixed between the opening and closing members below the guide plate and above the swing shaft and between the substrate and the front plate with the iron core facing sideways ;
One end face is exposed to the electromagnet side and is embedded in the axial portion below the guide plate of each of the pair of opening and closing members, and when the opening and closing member is in the closed position, the end face becomes the end face of the iron core. A permanent magnet arranged at the facing position ,
The reversing force between the electromagnet and the permanent magnet when the electromagnet is excited causes the open / close member to be in an open position,
When the electromagnet is demagnetized, the end face of the iron core and the end face of the permanent magnet are joined to each other by the attractive force between the permanent magnet and the iron core of the electromagnet, so that the opening / closing member is brought into the closed position.
Therefore, since a solenoid as a drive source and a mechanism for converting reciprocating motion into rotational motion are not required, the structure can be simplified and the size can be further reduced.
[0006]
The attractive force acting between the permanent magnet and the iron core of the electromagnet when the electromagnet is demagnetized also serves as a locking means for holding the opening / closing member in the closed position.
Further, since the permanent magnet is disposed on the axial portion of the opening / closing member, the opening / closing member does not need to be provided with a lower shaft portion that swings below the swinging shaft, and the magnet is disposed in the lower shaft portion. Compared to the case, it can be downsized. In other words, the arrangement of the permanent magnet on the axial portion of the opening / closing member is the result of pursuing downsizing.
[0007]
As described in the section of the prior art, there is a tulip type variable winning device as a kind of variable winning device. This tulip-type variable prize-winning device has a structure that swings a pair of opening and closing members arranged facing each other .
[0008]
Normally, in the tulip-type variable winning device, a passage for receiving a game ball is formed between the opening and closing members even when the opening and closing member is raised to the closed position, and the game balls received in the passage are guided to the receiving port. The guide member is disposed between the opening and closing members. Therefore, the space below the guide member is a space that is not used for the game ball.
The present invention has a guide plate that projects forward of the receiving port and guides the game ball to the receiving port when the opening / closing member is in the open position, and a lower end portion connected to the substrate on which the receiving port is provided by a connecting plate. A front plate that is arranged in parallel with the substrate and supports the swing shaft with the substrate, between the opening and closing members that are below the guide plate and above the swing shaft, and between the substrate and the substrate Since the electromagnet is disposed between the front plate and the internal space, the internal space is effectively used, which leads to downsizing of the apparatus.
[0009]
In addition, the electromagnet is fixed with the iron core facing sideways, and the permanent magnet is embedded in the upper part of the shaft below the induction plate of each of the pair of opening and closing members with one end face exposed to the electromagnet side. When the opening / closing member is in the closed position, the end face is disposed at a position facing the end face of the iron core,
When the electromagnet is demagnetized, the end face of the iron core and the end face of the permanent magnet are joined to each other by the attractive force between the permanent magnet and the iron core of the electromagnet, so that the opening / closing member is in the closed position. It works as a means.
In the present invention, as described in claim 2, the opening / closing member may be provided with a guide plate housing portion for avoiding interference with the guide plate when the open / close member is in the closed position .
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Next, two embodiments of the present invention will be described in detail with reference to the drawings.
[0011]
[Example 1]
As shown in FIGS. 1, 2, and 3, the variable winning device 10 according to the present embodiment has a structure in which each part is supported by a substrate 12, and a bullet ball (not shown) by a screw hole 14 provided in the substrate 12. It is equipped on the game board by screwing it to the game board of the gaming machine. The board 12 is provided with a receiving port 16 for receiving a game ball, and the back side of the receiving port 16 is connected to a guide rod 18 as shown in FIGS. In addition, as shown in FIG. 2, the bottom plate 20 of the guide rod 18 is in a series with the guide plate 22 arranged on the front side of the substrate 12, and is inclined so that the guide plate 22 side is high and the bottom plate 20 side is low. It has been.
[0012]
As shown in FIGS. 1 to 3, a front plate 24 that is parallel to the substrate 12 is disposed on the front side of the guide plate 22. As shown in FIGS. 1 and 2, the lower end portion of the front plate 24 is connected to the substrate 12 by a connecting plate 26. Further, as shown in FIGS. 2 and 3, the upper end portion of the front plate 24 is in a series with the guide plate 22.
[0013]
As shown in FIGS. 1 to 3, a pair of swinging shafts 28 are provided horizontally from the substrate 12 to the front plate 24, and a pair of opening / closing members 30 that are mirror images of each other are swingable by the swinging shafts 28. Is pivotally supported. Each of the opening / closing members 30 includes protrusions 32 protruding toward the other side, and when the opening / closing members 30 are brought close to each other as shown in FIG. Almost in contact with each other, a V-shaped guide path 34 is formed thereabove. In the state where the opening / closing member 30 is in the closed position, the distance between the tips of the opening / closing member 30 is slightly larger than the diameter of the game ball, and the game ball falling from above can be received in the guide path 34. Then, the received game ball can pass through the receiving port 16 and be discharged to the guide rod 18 side. Further, as shown in FIG. 2, when the opening / closing member 30 is oscillated and displaced toward the side separating from each other about the oscillating shaft 28 to be in the open position, the guide plate 22 and the protruding portions 32 on both sides are arranged. However, it will be in the state which continued along the gentle circular arc, and the game ball which falls from the upper part is received in the range of the protrusion part 32-guide plate 22-protrusion part 32, and it passes through the receiving port 16, and is on the guide rod 18 side. It can be discharged.
[0014]
As shown in FIGS. 2 and 3, an electromagnet 40 having a cylindrical iron core 38 is provided between the lower substrate 12 and the front plate 24 of the guide plate 22 so that both ends of the iron core 38 are on the opening / closing member 30 side. Installed sideways.
As shown in FIG. 3, a permanent magnet 42 is embedded in the opening / closing member 30 at a position facing the iron core 38 when the opening / closing member 30 is in the closed position. The poles on the electromagnet 40 side of these permanent magnets 42 are arranged so as to be opposite to each other (one with the S pole facing the electromagnet 40 and the other with the N pole facing the electromagnet 40). Further, the iron core 38 is set so that, when energized, the permanent magnet 42 side facing the electromagnet 40 is the S pole and the opposite side is the N pole. The opening / closing member 30 is provided with a guide plate housing portion 44 for avoiding interference with the guide plate 22 when this is set to the closed position.
[0015]
In this variable winning device 10, when the electromagnet 40 is not energized, the iron core 38 and the permanent magnet 42 of the electromagnet 40 attract each other, so that the opening / closing member 30 is in a closed position almost upright above the swing shaft 28. (See FIG. 1). At this time, as described above, only the game ball that has passed between the tips of the opening / closing member 30 can be received and discharged from the receiving port 16 to the guide rod 18.
[0016]
On the other hand, when the electromagnet 40 is energized and excited, the facing poles of the electromagnet 40 and the permanent magnet 42 become the same polarity, so the electromagnet 40 and the permanent magnet 42 repel each other, and the opening / closing member 30 has a swing shaft. It is oscillated and displaced so as to fall around the center 28 to be in the open position (see FIG. 2). At this time, since the distance between the tips of the opening / closing member 30 is increased, the game ball is easily received. When the energization of the electromagnet 40 is stopped, the opening / closing member 30 is brought into the closed position by the attractive force between the iron core 38 and the permanent magnet 42 as described above.
[0017]
As described above, in this variable winning device 10, the opening / closing member 30 can be changed between the open position and the closed position according to the on / off state of the electromagnet 40. Only the magnet 42 is used, and for example, a solenoid as a drive source, a mechanism for converting the reciprocating motion of the solenoid into a rotational motion, and the like are not required. Therefore, the structure can be simplified and further miniaturized.
[0018]
Further, the attractive force acting between the permanent magnet 42 and the iron core 38 of the electromagnet 40 when the electromagnet 40 is demagnetized also serves as a locking means for holding the opening / closing member 30 in the closed position. There is no possibility that the opening / closing member 30 is displaced to the open position due to a collision or the like.
[0019]
In addition, since the permanent magnet 42 is disposed on the axial portion of the opening / closing member 30, the opening / closing member 30 does not need to be provided with a lower shaft portion that swings below the swinging shaft 28, and the magnet is disposed on the lower shaft portion. The size can be reduced as compared with the arrangement structure.
[0020]
[Example 2]
Although not included in the scope of the present invention, an open / close structure using an electromagnet can also be applied to an attacker-type variable winning device.
As shown in FIG. 4, the variable winning device 50 of this embodiment includes a rectangular substrate 54 having an opening 52. A guide plate 56 that crosses the opening 52 protrudes on the back side of the substrate 54, and the opening 52 above the guide plate 56 serves as a receiving port 58.
[0021]
A swing shaft 60 is provided along the lower side of the opening 52, and the lower end portion of the opening / closing plate 62 corresponding to the inner peripheral shape of the opening 52 is pivotally supported so that the swing shaft 60 can swing. Yes. The opening / closing plate 62 is provided with a triangular member 64 that protrudes toward the receiving port 58, and the triangular member 64 enters and exits the receiving port 58 as the opening / closing plate 62 swings. Further, a permanent magnet 68 is embedded in the opening / closing plate 62.
[0022]
On the other hand, an electromagnet 70 held by the guide plate 56 is disposed below the guide plate 56. The magnetic pole generated at the end of the iron core 72 on the permanent magnet 68 side when the electromagnet 70 is energized is the same as the magnetic pole at the end of the permanent magnet 68 on the iron core 72 side.
In this variable winning device 50, when the electromagnet 70 is not energized, the iron core 72 and the permanent magnet 68 of the electromagnet 70 attract each other, so that the open / close plate 62 is in a closed position almost upright above the swing shaft 60. . At this time, since the receiving port 58 is blocked by the opening / closing plate 62, the variable winning device 50 cannot receive the game ball.
[0023]
On the other hand, when the electromagnet 70 is energized and excited, the facing poles of the electromagnet 70 and the permanent magnet 68 become the same polarity, so the electromagnet 70 and the permanent magnet 68 repel each other, and the opening / closing plate 62 has a swing shaft. It is displaced by swinging so that it falls around 60, and it becomes an open position. At this time, since the opening / closing plate 62 is separated from the receiving port 58, the game ball can be received in the receiving port 58. In addition, since the triangular member 64 functions to block the fall of the game ball falling from above and send it to the receiving port 58, the variable winning device 50 is in a state where it is very easy to win. When the energization of the electromagnet 70 is stopped, the open / close plate 62 is brought into the closed position by the attractive force of the iron core 72 and the permanent magnet 68.
[0024]
As described above, even in this variable winning device 50, the open / close plate 62 can be changed between the open position and the closed position in accordance with the on / off state of the electromagnet 70. Only the magnet 68 is used, and there is no need for, for example, a solenoid as a drive source or a mechanism for converting the reciprocating motion of the solenoid into a rotational motion. Therefore, the structure can be simplified and further miniaturized.
[0025]
Further, the attractive force acting between the permanent magnet 68 and the iron core 72 of the electromagnet 70 when the electromagnet 70 is demagnetized also serves as a locking means for holding the open / close plate 62 in the closed position. There is no possibility that the open / close plate 62 is displaced to the open position due to a collision or the like.
[0026]
In addition, since the permanent magnet 68 is disposed on the axial portion of the opening / closing plate 62, the opening / closing plate 62 does not need to be provided with a lower shaft portion that swings below the swinging shaft 60, and the magnet is disposed on the lower shaft portion. The size can be reduced as compared with the arrangement structure.
As described above, the embodiment of the present invention has been described according to the two examples. However, the present invention is not limited to such examples, and it goes without saying that the present invention can be implemented in various ways without departing from the gist of the present invention. Yes.
