Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable winning ball device used in a ball game machine represented by a pachinko game machine, a coin game machine, and the like, and more specifically, a mounting substrate having an opening for receiving a hitting ball. And a variable winning ball device that operates an opening / closing member, which is changeable between a first state in which it is easy to receive a ball and a second state in which it is difficult or difficult to receive a ball, by an electric drive source.

[0002]

2. Description of the Related Art In this type of variable winning ball device, an opening / closing member pivotally supported by a mounting substrate is used to swing back and forth with its lower side as a swing center. By doing so, the opening portion of the mounting substrate is configured to be switchable between the open state and the closed state so that it can be switched between the first state and the second state.

[0003]

However, this conventional device, when mounted on the game board of a ball game machine, falls from above when the opening / closing member is in the first opened state. The pachinko ball is received by the opening / closing member, but when the opening / closing member is in the closed second state, the pachinko ball dropped from above passes through the front side of the opening / closing member. Then, it falls without colliding with any obstacles, collides with lower nails and inner rails at a fast falling speed, and the impact at the time of collision becomes stronger. Fatigue damage occurs, which has the drawback that the life of the ball game machine is shortened.

In particular, the obstacle nail is required to have a proper function of giving a proper resistance to the dropping of the hitting ball, while the guide rail receives the dropping hitting ball and smoothly guides it to the out hole. Therefore, even if the amount of deformation caused by the impact of the hitting ball is small, the respective functions may be impaired. This means that the life of the ball game machine due to the impact collision of the hitting ball is reduced. There is a possibility that it may be a cause of increasing the shortening of.

Therefore, a hitting ball collision frame having at least an upper surface projecting forward is provided on the mounting board surface side below the opening of the mounting board for mounting the variable winning ball device on the game board surface, and the opening / closing member is the first. In the state of 2, the pachinko ball that has fallen from above collides with the hitting ball collision frame once and the drop collision force weakens, and then drops onto the obstacle nail or guide rail below. However, it is conceivable to solve the inconveniences such as the deformation of the obstacle nail and the guide rail and the fatigue damage described above. With this configuration, the front surface side of the mounting board below the opening is effectively used for the projection formation of the hitting ball collision frame, but the back surface side of the mounting board is also used for mounting the necessary equipment. If used effectively, it is desirable that both the front and back sides of the mounting substrate are effectively used.

The present invention has been conceived in view of the above circumstances, and an object thereof is to hit a ball which is formed so as to project forward at least on the upper surface side on the surface side of the mounting substrate below the opening of the variable winning ball apparatus. By providing a collision frame, it is possible to prevent deformation and fatigue damage that may occur in the obstacle nails and inner rails located below the opening / closing member when used in a ball game machine, and also to the back side of the mounting board. It is an object of the present invention to provide a variable winning ball device that is effectively used for mounting necessary equipment.

[0007]

According to the present invention, there is provided a mounting substrate having an opening for receiving a hitting ball, a first state in which the hitting ball is easily received in the opening and a second state in which the hitting ball is not accepted or is hard to be accepted. A variable winning ball device that operates an opening / closing member that can be freely changed to a state by an electric drive source, and a hitting ball collision frame in which at least an upper surface is formed to project forward on the surface side of the mounting substrate below the opening. A relay board for relaying a detection signal of a winning ball detection means for detecting a winning ball received in the opening, which is input to a game control board, on the back surface side of the mounting board. Is provided.

[0008]

According to the present invention, since the hitting ball collision frame is formed so as to project forward below the opening, the hitting ball that has dropped in front of the opening once collides with the hitting ball collision frame and the falling speed is reduced. Then, it collides with a lower inner rail or an obstacle nail. Therefore, since the hitting ball collides with the inner rail and the obstacle nail in a state where the drop collision speed is reduced, it is possible to prevent deformation and fatigue damage of the inner rail and the obstacle nail as much as possible. Moreover, on the back side of the mounting board, there is a relay board for relaying the detection signal of the winning ball detecting means for detecting the winning ball received in the opening and the signal inputted to the control board for game control. It is set up.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a variable winning ball device 1 for a ball game machine 1.
It is the whole front view showing the state where it was attached to 08.

A game board 114 is formed on the front frame 110 of the ball game machine 108. In this game board 114,
The variable display device 116 is provided, and the starting winning opening 11
The display state of the variable display device 116 is changed for a certain period of time and stopped in accordance with the winning of a ball hitting the balls 8a, 118b, 118c. The player operates the stop switch 122 to stop the variable display device 116 before the lapse of the predetermined time.

When the combination of the stopped symbols after the variable display device 116 is variably displayed is a predetermined fixed combination (for example, 777), the variable winning ball provided below the combination. An opening / closing plate 36, which is an example of an opening / closing member of the device 1, is configured to be opened for a fixed time (for example, 30 seconds). However, if a certain number of hit balls (for example, 10) are won while the opening / closing plate 36 is open, the opening / closing plate 36 is switched to the closed state before the fixed time (for example, 30 seconds) has elapsed. It is configured to be. The open / close plate 36 is in the open state to form the first state in which it is easy for the hit balls to win.
Further, the closed state of the opening / closing plate 36 constitutes a second state in which a ball cannot be won or is difficult to win.

In the figure, 104a and 104b are ordinary winning openings, and 112 is a glass door that covers the front of the game board 114.

The variable winning ball device 1 will be described with reference to FIG. FIG. 2 is a rear view showing the internal structure of the variable winning ball device 1. An opening 4 is formed in an upper portion of a mounting substrate 2 for fixing the variable winning ball device 1 to a game board. Opening / closing plate 3 for closing or opening this opening 4
6 is mounted on the mounting substrate 2 side by pivotally supporting both ends of the lower edge on the mounting substrate 2 side. This open / close plate 3
By opening and closing 6, you can win a ball at the opening 4
It is configured to be able to switch between the state of No. 2 and the second state in which it is difficult or difficult to win a ball. The open / close plate 36 is configured to be opened / closed by a solenoid 78 (see FIG. 5).

A specific winning port 65 is formed at a substantially central position of the opening 4, and the detector main body 64 can detect that a hit ball that has won the opening 4 has passed through the specific winning port 65. Is configured. The detector body 64 is provided with a swinging member 66, and the specific winning opening 6
When the pachinko ball passing through 5 collides with the swinging member 66, the passing of a hitting ball can be detected.

The ball hit from the opening 4 is a winning ball guide gutter 1 provided at the bottom of the winning ball gathering space 3.
It falls on 0. The winning balls that have fallen on the winning ball guiding trough 10 roll down in the lower right direction in the figure because the winning ball guiding trough 10 is tilted at a predetermined angle, and collide with the winning ball collision wall 18 to directly win the winning prize below. It falls to the ball exit 15. A prize winning ball detector 84 is attached to the prize winning ball outlet 15, and the prize winning balls dropped from the prize winning ball outlet 15 pass through the prize winning ball detector 84 to win the prize in the variable prize winning ball device 1. It is configured to detect the number of balls. The winning ball detector 84 is composed of a non-contact type proximity switch, and is inserted between the detector mounting plate 12 and the winning ball guiding trough 10 and fitted by a fitting groove 20. It is fixed by screws from 16. Reference numeral 13 in the figure is a current-changing projection, which reduces the falling speed of the winning prize ball once colliding with it and reduces the impact force when the falling ball collides with the opening end face of the game board. The purpose is to prolong the life of the opening end face. Further, in the figure, reference numeral 22 denotes a winning ball receiving portion which constitutes a winning opening for starting, and the hit ball dropped on the winning ball receiving portion 22 is guided backward by a winning ball guiding piece 24, and a starting winning ball detector (Fig. (Not shown) to drive the variable display device 116 described above.

In the case of the variable winning ball device 1 shown in FIG. 2, the winning ball outlet 15 is provided at a position displaced to one side with respect to the specific winning port 65, and the winning balls discharged from the winning port outlet 15 are provided. Since the winning ball detector 84 is configured to detect, a winning ball outlet is provided immediately below the specific winning port 65, and a winning ball device of a type that detects a winning ball discharged from the winning ball outlet is provided. Has a drawback, that is, when the winning speed of the winning balls that have won in the variable winning ball device 1 is high, the detection of the winning ball detector 84 may be impossible even though the detection by the specific winning port 65 is performed. , A fraud prevention device provided to deal with fraud such as pulling out the winning ball detector 84 (for example, Japanese Patent Laid-Open No. 61-982).
(Disclosed in Japanese Patent Publication No. 73) can be avoided.

Next, the force applied to the winning ball guided to the winning ball exit 15 by the winning ball guiding trough 10 will be described with reference to FIGS. 3 (A), (a), (B) and (b). To do.

First, as shown in FIG. 3 (A), in consideration of the static balance of force, the winning ball P ₃ has a rolling force r, from the succeeding winning balls P ₁ , P ₂ . In addition to r, the reaction force F from the winning ball collision wall 18 is further added, and the own weight G is added. Then, as shown in FIG. 3A, the resultant force Q of the external force 2r received from the subsequent winning ball and the reaction force F received from the winning ball collision wall 18 acts downward. Therefore, the force of G + Q acts on the winning ball P ₃ as a downward force. That is, as the number of subsequent winning balls increases, the value of Q increases, and the force for pushing the winning ball P ₃ downward increases, and the winning ball exits the winning ball exit 1
On the 5th, it does not happen that it is clogged due to ball biting or the like. Moreover, when the winning ball P ₃ rolls on the winning ball guiding trough 10 and collides with the winning ball collision wall 18, the winning ball P ₃ bounces downward and leftward in the figure at the same angle as the collision angle with the winning ball collision wall 18. From this point as well, the winning ball P ₃ easily falls into the winning ball exit 15. Further, the winning ball collision wall 18 is for holding the winning balls rolling on the winning ball guide trough 10 there, and the angle of the collision wall does not necessarily have to be vertical.
It is sufficient that the angle is substantially right angle to the upper surface of 0 or less. In particular, when the inclination angle of the collision wall surface is tilted to the left in the drawing with respect to the vertical surface, the winning balls collide and bounce downward, and It becomes easier to get depressed.
Further, when the winning ball detector 84 is mounted, since the fitting groove 20 is formed and mounted in the fitting groove 20, the projection amount of the end K of the winning ball detector 84 is reduced. ,
It is possible to prevent as much as possible the collision of the winning ball with the end K and the upward bouncing and the occurrence of a bridge phenomenon such as ball catching between the winning balls P ₁ and P ₂ . Further, reference numeral 12 in the drawing denotes a detector mounting plate for assembling and holding the winning ball detector 84.

Next, as shown in FIG. 3 (B), let us consider the static force balance of the winning ball in the longitudinal section of the variable winning ball device.

The external force applied to the prize ball P ₄ is the external force r from the prize ball P ₅ above it, the reaction force F from the back cover plate 50, and the reaction force V from the prize ball guide trough 10. Due to the balance of the three forces, a closed force polygon is formed as shown in FIG. When the forces of F and r become large, the winning ball P ₄ becomes difficult to move freely, and a bridge phenomenon such as ball biting easily occurs. Therefore, it is necessary to minimize these two forces of F and r. Therefore, it is necessary to make the angle θ as small as possible.
Therefore, it suffices to reduce the gap g shown in FIG. 3B. In this embodiment, the mounting substrate 2 and the back cover are covered.
The engaging step portions 61 and 60 are formed on the plate 50, respectively, and the winning ball detector 84 is embedded and held in the engaging step portions 61 and 60, and the embedded amount (t The distance of d is narrowed by ₂ + t ₃ ), and the length of g is made as small as possible.

FIG. 5 is a vertical sectional view showing the internal structure of the variable winning ball device. The variable winning ball device 1 is attached and fixed to the game board 94 by the attachment substrate 2. In the figure, reference numeral 78 denotes a solenoid which is an example of an electric drive source, and in a normal state where it is not excited, the extension force of the return spring 81 causes the plunger 79 to extend downward. And only when it is excited, the return spring 8

An operating plate 80 is attached to the tip of the plunger 79, and as the plunger 79 is pulled up, the engaging projection 82 of the operating plate 80 pushes up the open / close plate opening restricting portion 46 of the open / close plate 36. Open / close plate 36
Is opened so that a hit ball can win a prize from the opening 4. Further, reference numeral 47 in the figure denotes an opening / closing plate stopper portion for restricting the opening / closing angle of the opening / closing plate 36 by contact with the opening / closing plate opening restricting portion 46 in the opened state of the opening / closing plate 36. Further, reference numeral 48 in the drawing denotes an opening / closing plate closing regulation portion, which is pushed down by the engaging projection 82 when the solenoid 78 is de-excited and the plunger 79 is extended again. Opening and closing plate 36
Is configured to switch to a closed state. And

The static force balance of the winning balls discharged from the winning ball outlet 15 while rolling on the winning ball guide gutter 10 will be described with reference to FIG. The forces R ₁ and r _{2 in the} rolling direction are applied to the preceding winning balls P ₃ from the succeeding winning balls P ₁ and P ₂ , respectively, and further, the reaction force F from the winning ball collision wall 18 is added. A resultant force Q of the reaction force F and the external force r ₁ + r ₂ is generated downward (see FIG. 10B). Therefore, the winning ball P ₃ has its own weight G + Q as a downward force.
Will work. As shown in FIG. 10B, the force of Q is proportional to the magnitude of the external force r ₁ + r ₂ received from the subsequent winning balls, and the more the number of succeeding winning balls increases, the more the winning balls. The force Q for pushing P ₃ downward becomes large, and the winning balls are discharged smoothly from the winning ball outlet 15 without causing a bridge phenomenon such as ball biting. In the figure, reference numeral 86 is a winning ball passage hole formed in the winning ball detector 84.
