Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a winning ball device for a pinball game machine typified by a pachinko game machine, etc., and more specifically, the present invention relates to a winning ball device for a pinball game machine typified by a pachinko game machine, etc. The present invention relates to a winning ball device that is attached to a game board of a pinball game machine using the mounting board.

[Prior Art] Conventionally known winning ball devices for this type of pinball game machine include, for example,
There was one described in Utility Model Publication No. 56-4054. The winning ball device of this conventional pinball game machine is provided with an obstacle member that collides with the balls hit on the mounting board located above the winning area, and is opened and closed on the front side of the front plate of the mounting board below the obstacle member. The member is provided so that it can be opened and closed freely,
When the opening/closing member is in the open state, it becomes easier for balls to enter the winning area, and when the opening/closing member is in the closed state, it becomes difficult for balls to enter the winning area. It was configured to be located inside the outermost end in the left and right direction. Furthermore, a winning hole was formed in the mounting board above the obstacle member. By forming a winning hole not only in the winning area but also in the mounting board above the obstacle member, the chances of hitting a winning ball are increased and the game becomes more interesting. was. Even if the opening/closing member of the winning ball device is in the closed state, the ball may be shot out aiming at the winning hole. If the ball falls downward without entering the winning hole and collides with the tip of the opening/closing member that is in the closed state, the tip of the opening/closing member may prematurely close due to the impact force at the time of collision. However, in the conventional winning ball device, the tip of the opening/closing member in the closed state is located inside the outermost end of the obstruction member in the left and right direction, and It was configured to prevent the ball from colliding with the tip of the opening/closing member in the closed state.

[Problems to be Solved by the Invention] However, in the winning ball device of this type of conventional pinball game machine, it is difficult to make the ball hit into the winning area even when the opening/closing member is in the closed state. Because of this structure, whether the opening/closing member is in the open or closed state, it is possible to win a prize within the winning area, so the game lacks sharpness and is not very enjoyable. There was a drawback that it did not increase the interest of the movie.

Therefore, it is conceivable to configure the game so that when the opening/closing member is in the closed state, the balls can be placed in the winning area to add variety to the game.

However, when configured in this way, compared to the conventional winning ball device described above, when the opening/closing member is closed, the hit ball does not enter the winning area at all, so the hit ball does not win a prize when the opening/closing member is closed. This results in a new inconvenience in that the player's attention is drawn away from the winning ball device when it is in the closed state.

Therefore, this winning hole is enlarged to make the chance of winning a prize with a ball hit into this winning hole at least apparently larger, and to prevent the player's attention from shifting away from the winning ball device when it is in the closed state as much as possible. It is possible that However, in order to increase the diameter of the winning hole, it is necessary to increase the size of the mounting board portion where the winning hole is formed accordingly.
As a result, an inconvenience arises in that the area on which the obstacle nails are provided on the game board is reduced. In other words, the obstacle nail has functions such as adjusting the winning rate of balls to a favorable value by adjusting the nail, or randomly changing the falling trajectory of the ball, and the area where this obstacle nail is installed is reduced. This creates a new inconvenience. On the other hand, if the area of the mounting board in which the winning ball device is formed is reduced, the strength of the mounting board around the winning hole will be insufficient, and if the mounting board itself is removed, it will be necessary to attach the winning ball device to the gaming board. The opening formed in the opening is visible to the player, which is undesirable in terms of design.

The present invention was devised in view of the above-mentioned circumstances, and its purpose is to make it impossible for balls to enter the winning area when the opening/closing member is closed, and to prevent the game from occurring in the winning area. In order to improve the sharpness and prevent the player's attention from shifting away from the winning ball device when it is in the closed state,
It is possible to maintain sufficient strength without increasing the area of the mounting board portion in which the winning hole is formed, and also prevents the inconvenience that the opening formed in the game board for attaching the winning ball device is visible to the player. To provide a winning ball device for a pinball game machine that can be used.

[Means for Solving the Problems] The present invention is a winning ball device that has a mounting board and a winning area, and is attached to a game board of a pinball game machine by the mounting board, and is located above the winning area. an obstacle member provided on the front side of the mounting board and with which the balls collide; and an obstacle member provided below the obstacle member on the front side of the mounting board so as to be freely openable and closable, and in an open state, the balls hit the winning area. A pair of left and right opening/closing members whose tips are located inside the outermost ends in the left and right direction of the obstacle members; , a winning hole formed in the mounting board part above the opening/closing member, and ball guiding paths that receive the balls and guide them to the winning hole are formed on the left and right sides of the winning hole. do.

[Function] According to the present invention, when the opening/closing member is in the open state, the ball can enter the winning area, and when the opening and closing member is in the closed state, the ball cannot enter the winning area. The sharpness of the game regarding the area is improved. Furthermore, when the opening/closing member is in the closed state, the tip of the opening/closing member is located inside the outermost end of the obstruction member in the left and right direction, so that a ball falling from above may be in the closed state. Collision with the tip of a certain opening/closing member can be avoided as much as possible. Furthermore, a winning hole is formed in the mounting board above the obstacle member, and a ball guiding path that receives the ball and guides it to the winning hole is located on the left and right sides of the winning hole. Because of this formation, it is possible to give the player the impression that the ball that has fallen on the ball guiding path is guided to the winning hole and that the ball is likely to win a prize in the winning hole, and when the ball is in the closed state. It is possible to prevent the player's attention from shifting away from the winning ball device as much as possible.
Moreover, it is not necessarily necessary to increase the size of the winning hole itself.

FIG. 7 is a circuit diagram of a drive control circuit for explaining the operation of a winning ball device according to an embodiment of the present invention. Next, the operation of the winning ball device 20 of this embodiment will be explained with reference to FIGS. 1 to 7. first,
A case will be described in which the pair of arm members 36a and 6b are opened. When a hit ball enters the winning hole 32, the ball detection switch 22 derives a winning ball detection output and provides it to the arm member drive circuit 61. In response, arm member drive circuit 61 energizes solenoid 42 . In response, the solenoid 42 sucks the plunger 421 upward, so that the connecting member 43 is pulled upward. For this reason, levers 44a and 44b
Since the pin 441 of the connecting portion is pulled upward, the open ends of the levers 44a and 44b are rotated downward. In conjunction with the rotation of levers 44a and 44b, arm members 36a and 36b rotate outward, respectively. At this time, the operating lever 56
The pins 562 of a and 56b are the solenoids 52a and 5
Since 2b is not biased, it is not slid within the guide hole 313. As a result, when only the solenoid 42 is energized, only the pair of arm members 36a and 36b are in the open state, and the ball receiving pieces 37a and 37b are in the upright state. This situation is shown in FIGS. 5A and 5B.

In this state, the reason why the hit ball enters the winning hole 33 is because the hit ball is connected to the guide wall 342 and the ball receiving piece 37.
This is the case when the object passes through the area or space between the upper end of the object a or the upper end of the object 37b. For this reason, the probability that the ball will enter the winning hole 33 is slightly higher than when the arm members 36a and 36b are closed, or the ball receiving piece 37a,
37b is opened. Then, the driven ball is connected to the guide wall 342 and the ball receiving piece 37a or 37.
When the ball passes through the space between the upper end of the arm member 36a or 36b, the ball is guided to the winning hole 33 while rolling on the upper surface of the arm member 36a or 36b.

In the state where the pair of arm members 36a and 36b are open as described above, the arm member drive circuit 61
An activation signal is sent from the ball drive circuits 62 and 63.
is given to. In this state, when a ball hits the winning hole 34a, the ball detection switch 23
detects it and supplies it to the ball receiving piece drive circuit 62.
The ball receiver piece drive circuit 62 energizes the solenoid 52a in response to an activation signal being given from the arm member drive circuit 61 and an output from the ball detection switch 23. The solenoid 52a moves the plunger 521 toward the center, that is, toward the L-shaped lever 55a, in response to electrical bias. Therefore, the L-shaped lever 55a is rotated toward the center, and the pin 562 of the operating lever 56a is rotated toward the center (toward the winning hole 33 side).
Move to. At this time, the ball receiving piece 37a is
Since the arm member 36a that pivotally supports the lever 71 remains fixed, the pin 372 is pulled toward the center in conjunction with the movement of the lower end of the operating lever 56a using the pin 371 as a fulcrum. Therefore, the ball receiving piece 37a
rotates counterclockwise to the open state. This state is the state shown in FIG. 6A (that is, the ball receiving piece 37a
is open and the ball receiving piece 37b is in a closed state as shown by the two-dot chain line). In this state, the ball falling from the upper left direction of the winning hole 33 is placed on the ball receiving piece 37.
a and is received by the winning hole 3 through the arm member 36a.
Leads to 3.

In addition, when a ball enters the winning area 34 and is distributed to the winning hole 34b by the distribution piece 334, the winning ball is detected by the ball detection switch 24. In this case, the ball holder drive circuit 63 responds to the output of the ball detection switch 24 by controlling the solenoid 5.
2b to open the ball receiving piece 37b. Note that if the arm members 36a and 36b are not opened, the ball may be hit in the winning hole 34a or 3.
4b, the activation signal is not given from the arm member drive circuit 61, so the ball receiver piece drive circuit 62 or 63 activates the solenoid 52a or 52b.
Do not energize.

On the other hand, when the hit ball passes through the winning area 14, the ball detection switch 25 detects it. The output of the ball detection switch 25 is given to an arm member drive circuit 61 and ball support piece drive circuits 62 and 63. In this case, the pair of arm members 36a and 36b are opened and the ball receiving piece 3 is opened in the same manner as the above-mentioned operation.
7a and 37b are opened. In other words, the ball receiving member driving means can change the receiving area of the driven balls by the ball receiving member, and therefore the ball receiving member driving means can change the opening amount of the ball receiving member. It includes a variable opening amount ball receiving member driving means that can change the receiving area of balls by changing the opening amount. In addition, since the receiving area of the hit ball changes depending on which winning area the hit ball wins,
The variable opening amount ball receiving member driving means includes variable opening amount driving means corresponding to winning openings that changes the opening amount depending on which of the plurality of winning openings provided on the game board the ball has won. include. Note that the arm member 36
The conditions for closing a and 36b are as follows: drive circuits 61 to 6
It is selected as appropriate depending on the circuit configuration of No. 3. For example, the conditions for closing the pair of arm members 36a, 36b and the ball receiving pieces 37a, 37b are such that a certain period of time has elapsed since the opening of the arm members, or a certain number of balls have entered the winning hole 33.
will be selected before entering the prize.

As described above, according to this embodiment, since the arm member and the ball receiving piece operate in two stages, there is an advantage that there are many changes in the state in which it is easy to win a prize into the winning hole 33. In addition, compared to a device in which the ball holder piece is directly rotated instead of the arm member, the storage space for the arm member and ball holder piece in the closed state is smaller, but when the arm member and the ball holder piece are opened, It has the advantage of being able to receive balls over a large area, greatly increasing the winning probability, and greatly improving the service provided to players.

In addition, in the above-mentioned embodiment, when opening only one pair of arm members as a condition for opening the arm members and ball receiver pieces, one of the left and right ball receiver pieces is opened with one pair of arm members opened. Three cases have been described, in which the pair of arm members and the left and right ball receiving pieces are opened at the same time. However, the technical concept of the present invention is not limited to these conditions, and open driving may be performed under other conditions. For example, 1
In the state where the pair of arm members are opened, the left and right ball receiving pieces may be opened simultaneously based on a predetermined gaming state.

[Effects of the Invention] According to the present invention having the above-mentioned configuration, when the opening/closing member is in the closed state, the ball cannot enter the winning area. Since ball guiding paths are formed on the left and right sides of the winning hole to guide the ball to the winning hole, it is possible to prevent as much as possible the problem of the player's attention being drawn away from the winning ball device when the opening/closing member is in the closed state. Moreover, in order to prevent this inconvenience, it is not necessary to increase the size of the winning hole itself.
Sufficient strength can be obtained without increasing the size of the mounting board around the winning hole, and the mounting board around the winning hole allows the opening formed in the game board to attach the winning ball device to the game board. can be hidden from the player's view.
