Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a ball game machine such as a pachinko machine,
More specifically, the present invention relates to a ball game machine capable of adjusting a winning rate for a variable winning device in which a game ball (hit ball) hit on a game board surface can be converted into a first state in which it is difficult to win and a second state in which it is easy to win.

[Prior Art] For example, in a pachinko gaming machine, the probability that a hit ball wins a winning opening changes depending on the position and direction of the nails arranged on the game board surface, the bending angle, the interval between the nails, and the like. For this reason, adjusting nails is an important task for pachinko parlors, and for players, finding a pachinko machine that is adjusted so that balls often come out is one of the conditions for winning more prize balls. There is.

However, adjusting the direction and spacing of the nails, which determines the winning rate of the hit ball, is a very delicate work performed in units of 0.01 mm, and requires an expert with skilled adjustment technology.

Therefore, the following device has been proposed as a device for adjusting the winning rate of a hit ball by automatically adjusting the nails of a pachinko machine.

The opening of a pair of nails provided above the winning opening is changed within a certain range (Japanese Patent Publication No. 59-35633).
No.), the position or inclination of the nails provided in each winning portion is changed according to the winning rate of each winning opening (Japanese Patent Publication No. 61-36).
No. 949).

On the other hand, there is also known a technique of variably controlling the winning rate by setting the opening time of a variable winning device such as a tulip instead of adjusting the nail. For example, the opening time of the winning device is controlled so that the profit index of a pachinko parlor is set within a certain range (Japanese Patent Laid-Open No. 54-7823).
No. 3), the opening time of the variable winning device is specified based on a random number generated electronically (Japanese Patent Publication No. 61-47548).
issue).

[Problems to be Solved by the Invention] However, in the above-described device for adjusting nails, since it is required to perform delicate adjustments with high precision, the adjustment mechanism becomes precise and expensive, and the conventional mechanism It is practically difficult to adopt as an alternative to manual labor.

Further, even if the opening time of the variable winning device is set as described above, it is difficult to finely variably set the winning ratio as in the nail adjustment.

Furthermore, in the conventional pachinko machine that is finely adjusted as described above, the degree of hitting ball winning depends on the skill of the player, and it is difficult for the player to put out the ball unless the player is a specific expert. There is also a problem that it lacks equality as a game for the general public.

The present invention has been made in view of such problems,
It is an object of the present invention to provide a ball-and-ball game machine in which prize balls can be obtained with an equal probability regardless of the skill of a player and nail adjustment is not required.

[Means for Solving the Problem] The present invention relates to a launching device for launching a game ball onto a game board surface,
A ball game machine provided with a variable winning device arranged on a game board surface and capable of converting a game ball launched from the launch device into a first state in which it is difficult to win a prize and a second state in which it is easy to win a prize. Driving means for alternately converting and driving the winning device into the first state and the second state, winning ball detecting means for detecting a game ball won in the variable driving device that is conversion driven, and a detection signal from the winning ball detecting means. Winning ball counting means for counting the number of winning balls by means of a ball, detecting means for detecting a game ball emitted from the launching device, and counting a number of balls by a detection signal from the means for detecting a ball. Means, and during the game period until the count value of the fired ball counting means reaches a predetermined first value, the drive means is caused to carry out the conversion drive of the variable winning device, and the winning ball count during the game period. Count value of means Upon reaching the second value determined in advance, characterized in that the conversion driving of the variable winning device and a control means for stopping at said first state.

According to a preferred aspect of the present invention, the launch ball detecting means can be detected or the launch ball counting means can accept the detection signal from the launch ball detecting means while the launching device is operating.

Further, according to a preferred aspect of the present invention, the launch ball detecting means is arranged at the game ball launching position of the launching device, and the launch ball detecting means detects the game ball at the launching position, and thereafter does not output the detection signal. It is assumed that the firing ball counting means counts the number of firing balls by one.

Further, according to a preferred aspect of the present invention, the launch device does not operate when the launch ball detection means arranged at the game ball launch position does not output a detection signal.

Further, in a preferred aspect of the present invention, a plurality of variable winning devices are provided, and the control means controls the plurality of variable winning devices until the count value of the firing ball counting means reaches the first value during the game period. The conversion driving is performed simultaneously, and when the count value of the winning ball counting means reaches the second value, the driving is stopped at the same time.

Further, in another preferred embodiment, a plurality of variable winning devices are provided, and the control means sequentially controls the plurality of variable winning devices until the count value of the firing ball counting means reaches the first value during the game period. It is configured to perform conversion driving one by one, and when the count value of the winning ball counting means reaches the second value, the variable winning device during conversion driving is stopped.

[Operation] In the ball game machine of the present invention, the variable winning device is driven to convert the game ball into the first state in which the game ball is hard to win and the second state in which the game ball is easy to win. The game period is divided into one division until the count value reaches a predetermined first value, that is, until a predetermined number of game balls are shot. During this game period, the count value of the winning ball counting means reaches a predetermined second value. That is, when a predetermined number of game balls are won in the variable winning device, the variable winning device in the conversion drive is stopped in the first state. If a predetermined number of game balls are not won during the above game period, the game balls are carried over to the next game period.

Thus, the players are given equal opportunity to win the prize, and in the playground, the winning ratio can be managed without the conventional nail adjustment.

As a preferred aspect of the present invention, by activating the launch ball detecting means or the counting means while the launching device is operating, it is possible to prevent illegal input to the launch ball detecting means.

In addition, the launch ball detecting means is arranged at the game ball launching position of the launching device, and after the launch ball detecting means detects the game ball, the counting means counts one shot ball when the detection signal is no longer output. Therefore, the number of launch balls can be grasped. In this case, the illegal act can be prevented by preventing the launching device from operating when the launch ball detecting means does not output the detection signal.

Further, when a plurality of variable winning devices are provided, the control means sets them all at once, or each of them sequentially sequentially makes 2 times.

In the case of the former, a plurality of variable winning devices, during the above game period,
The conversion value is simultaneously driven until the count value of the firing ball counting means reaches the first value, and the count value of the winning ball counting means is changed to the second value in the meantime.
When the value of is reached, it is stopped all at once. This allows
It becomes easier for the player to recognize the conversion drive of the plurality of variable winning devices.

In the latter case, the conversion-driven variable winning device will circulate,
While the display is interesting, the variable prize winning device that is in the conversion drive is stopped when a predetermined number of game balls are won, so the conversion drive state change of the variable prize winning device is changed compared to the case where all are stopped at the same time. It is gentle and does not give the impression that the advantageous state for the player ends abruptly.

[Embodiment] FIG. 1 is a front view of a pachinko gaming machine which is an embodiment of the present invention. On the gaming board surface 2 of this pachinko gaming machine 1,
In addition to a fixed winning opening, an appropriate number (for example, 3) of variable winning devices (so-called tulips) 3 are provided. Further, a large number of nails 4 are arranged as a guide means for guiding the game ball hit on the game board surface 2 to the winning opening or the upper part of the variable winning device 3. A ball hitting handle 5 is provided on the lower right side of the front part, and the player operates the ball hitting handle 5 so that the launcher mounted on the back side of the game board can be used to play the game board surface 2
A game ball is launched between the upper guide rails 6 and 7.

The variable winning device 3 is for converting a game ball, which is launched from a launching device described later, onto the game board surface 2 into a first state in which it is difficult to win and a second state in which it is easy to win, for example, as shown in FIG. Is composed of.

First, the variable winning device 3 is the game board surface 2 via the mounting plate 41.
Be attached to. On the front side of the mounting plate 41, a pair of movable pieces 42a,
42b is arranged to be openable and closable, and a cover member 43 covers the lower part thereof. The variable winning device 3 includes a pair of movable pieces 42a,
When 42b is closed as shown in FIG. 10, the game ball is in the first state where the prize cannot be won, and when it is opened as shown in FIG. 11B, the game ball is in the second state where the prize can be won.

A solenoid 44 is arranged on the back surface of the mounting plate 41, that is, on the back side of the game board surface 2. The solenoid 44 is attached to the back surface of the game board via the bracket 45 that stores the solenoid.
At the upper and lower ends of the plunger 46 protruding above and below the solenoid 44,
Circular engagement plates 47 and 48 are fixed to each other, and the disc 47
A coil spring 49 is arranged between the upper surface of the bracket 45 and the upper surface of the bracket 45. When the solenoid 44 is energized and excited, the lower end of the plunger 46 projects downward from the state shown in FIG. After that, when the energization is stopped and the solenoid 44 is demagnetized, the plunger 46 is returned to the original state by the force of the coil spring 49. The variable winning device 3 opens and closes the pair of movable pieces 42a, 42b by utilizing the movement of the plunger 46.

A light emitting body (not shown) such as a light bulb is installed inside a substantially semicircular recess provided in the center of the lower portion of the cover member 43. This is lit or blinked when the pair of movable pieces 42a, 42b is opened and closed as described later. On the front side of the cover member 43, a light-transmissive disc 50 that scatters and transmits light from the light-emitting body.
Is installed.

Next, as shown in FIGS. 11A and 11B, a pair of movable pieces
Each of 42a and 42b has a cylindrical base portion, and is rotatably supported inside a cover member 43 by an eccentric shaft 51 provided on the front side of each base portion.

Between the bases of the movable pieces 42a, 42b and the solenoid 44, there is provided a motion transmission member 52 for converting the vertical reciprocating movement of the plunger 46 into the opening / closing movement of the movable pieces 42a, 42b. The motion transmitting member 52 is mainly composed of a rectangular plate, and projections 53 provided on the left and right end surfaces thereof.
It is rotatably supported by support portions 41a, 41b extending rearward from the left and right ends of the mounting plate 41 with a and 53b as fulcrums. In addition, the motion transmitting member 52 is a disc below the solenoid on the back side.
A pair of transmission rods 55 having L-shaped convex portions 54 sandwiching 48 and extending toward the bases of the corresponding movable pieces 42a, 42b are provided on the front side.
a, 55b. The tip of each transmission rod 55a, 55b is formed thin, and the holes 56a, 56b provided on the back side of the base of each movable piece 42a, 42b.
Is slidably inserted into.

Between the bases of the pair of movable pieces 42a, 42b, a winning ball receiving portion 58 having a triangular convex portion 57 which receives the game ball won when the movable piece is opened and is directed to the rear is arranged below the winning ball receiving portion 58. A gutter 59 for discharging prize balls is provided on the rear side. The winning ball receiving section 58 is
In addition to receiving a winning ball, when the pair of movable pieces 42a, 42b is opened, the convex pieces 60a, 60b protruding downward from the base of each movable piece are locked to move the pair of movable pieces 42a, 42b to the eleventh. It has a function of holding it in an open state as shown in FIG.

According to the variable winning device 3 configured as described above, when the solenoid 44 is not driven, the pair of movable pieces 42a and 42b are closed as shown in FIGS. 10 and 11 (A). Here, when the solenoid 44 is energized and excited, the plunger 46 is lowered against the spring 49, and the convex portion 54 of the motion transmission member 52 is pushed down via the disk 48 at the lower end thereof. Therefore, the motion transmission member 52 rotates, and the front transmission rod 55a,
Lift 55b. As a result, as shown in FIG. 11 (B), the pair of movable pieces 42a, 42b open to the left and right, and the lower convex pieces 60a, 60b stop when they hit the winning ball receiving portion 58. As a result, the game balls can be won, and the prize balls are discharged from the prize ball receiving portion 58 through the gutter 59 into the prize ball passage.

On the other hand, when the energization is stopped and the solenoid 44 is demagnetized, the force of the coil spring 49 returns the plunger 46 to the original state. By the upward movement of the plunger 46, the operation transmission member
52 rotates in the opposite direction to the above to lower the transmission rods 55a and 55b. As a result, the pair of movable pieces 42a, 42b is closed.

Next, as a game ball launching device, for example, one as shown in FIG. 2 is used. The launching device 9 is composed of a ball hitting portion 11 including a solenoid that causes the plunger 10 to be projected by an electromagnetic force and causes the game ball P to pop out, and a hitting ball guide portion 12 provided on the plunger protruding side. Hitting ball guide 12
Is formed by a cylindrical member that is cut out toward the tip for feeding the game ball P, and a pair of parallel members that guide the game ball P flipped by the tip of the plunger 10 forward on the inner bottom surface thereof. It has a ridge 13.

The present embodiment has the following features in addition to the above configuration.

First, the solenoid 44 of the variable winning device 3 is used during the game (actually, when the player operates the hit ball handle 5 to turn on the switch of the launching device 9), the control means 34 (seventh embodiment) described later.
As a result, the pair of movable pieces 42a, 42b are driven so as to be alternately converted into a closed state and an open state.

In addition, in the present embodiment, when the number of game balls launched from the launching device 9 reaches a predetermined number (a first value determined in advance), this is set as one segment. During this interval (for example, until 15 shot balls are shot), a predetermined number (a predetermined second value, for example, 1) of game balls are won in any of the plurality of variable winning devices 3. At this time, the variable winning device 3 that is being converted and driven is stopped in the first state (closed state).

If a predetermined number of game balls are not won during the above-mentioned one division, the credit is given to the next one division.
That is, in the next one division, the variable winning a prize device 3 is converted and driven until a predetermined number of double (for example, two) game balls are won.

Thus, in the above example, the ratio of winning the winning balls (winning rate) to the variable winning device in one segment is 1/15 because there is one winning ball for every 15 shooting balls.

As a method of driving the plurality of variable winning apparatuses 3, there is a method of converting and driving all of the variable winning apparatuses 3 simultaneously, or a method of sequentially converting and driving each winning apparatus into two states (opening and closing) once.

In the case of the former, the plurality of variable winning a prize devices 3 are converted and driven all at once until a predetermined number of launch balls (the first value) are reached,
In the meantime, when the number of winning balls reaches a predetermined number (the second value), they are stopped all at once. In this way, it becomes easy to recognize that the variable winning device 3 has been changed from the advantageous state to the disadvantageous state for the player.

On the other hand, in the latter case, the conversion-driven variable winning a prize device 3 circulates, the display is interesting, and when the number of winning balls reaches a predetermined number, the conversion-driving variable winning device 3 stops. The change state of the conversion drive of the variable winning a prize device is gentle compared with the case where all stop simultaneously. This can be said to be preferable in that it does not give the player the impression that the advantageous state ends suddenly.

Next, it is necessary to count the game balls (launch balls) P launched from the launch device 9, but at that time, the game balls (return balls that do not reach the game board surface 2 and return to the launch device 9). ) Is excluded from the number of launch balls. Therefore, the means for detecting the number of launch balls and counting the number thereof is configured as follows.

First, as shown in FIG. 2, the launch ball sensor 14 is arranged in front of the launching device 9. This launch ball sensor 14
Is composed of a magnetic sensor having a hole through which the output can be passed.

The launch ball P emitted from the launching device 9 passes through the launch ball passage 15 and rises along the guide rail 6 toward the game board surface 2 as shown in FIG. 3, but does not reach the game board surface 2. The return ball P ′ returning to the launching device 9 falls into the recovery path 16. In order to detect this, a return ball sensor 17 is arranged in the middle of the collection path 16. The output of the return sphere sensor 17 is also sent to the addition / subtraction counter 31 described later.

Next, as shown in FIG. 4, a launch ball sensor may be arranged at the ends of the pair of guide rails 6, 7 on the game board surface 2.
In this case, an annular magnetic sensor 21 is used as the launch ball sensor.
When the a and 21b are arranged side by side in the moving direction of the launch ball P, and when the magnetic sensors 21a and 21b sequentially detect the launch ball P that is launched from the end of the guide rails 6 and 7 onto the game board surface 2, the number of launch balls is calculated. To count. On the other hand, when the game ball does not reach the game board surface 2 and returns to the launcher 9, the magnetic sensor 21
a, 21b is not detected, even if the magnetic sensor 21a detects, the magnetic sensor 21b does not detect, the magnetic sensor 21a, 21b
The magnetic sensor 21a detects again after both of
There are three possible cases. However, in the cases of and, the number of fired balls is not counted, and in the case of 1, the number of fired balls is subtracted by one.

Alternatively, as shown in FIG. 5, a launch ball sensor 22 composed of a reflection type sensor may be arranged at the launch position in front of the launch device 9 to detect whether or not there is a game ball P at the launch position. Good. In this case, as shown in FIG. 6, when the launch ball sensor 22 detects the game ball P at the launch position (H level signal), and then no longer detects the game ball (at L level). ) It is assumed that one has been fired.

By the way, in the embodiment shown in FIG.
There is a risk that illegal input will be added to 21a and 21b. For example, in the case of a magnetic sensor, a magnet may be used, and in the case of an optical sensor, a light may be used to give an illegal input. Therefore, there are the following methods as measures to prevent this.

First, when the solenoid of the launching device 9 is operating, the launch ball sensors 21a, 21b or the addition / subtraction counter 31 are activated.

For example, if 100 game balls are launched from the launching device 9 per minute, the solenoid of the launching device 9 is about 0.6.
Energization (excitation) and de-energization (demagnetization) are repeated at a cycle of seconds. During the operation time of such a launch device, the launch ball sensor 21
The a, 21b or the addition / subtraction counter 31 is activated. That is,
The firing ball sensors 21a and 21b are set in a detectable state, or the addition / subtraction counter 31 is set in a state in which a detection signal from the firing ball sensors 21a and 21b can be accepted.

Alternatively, while the launching device 9 is operating, the launch ball sensors 21a, 21b or the addition / subtraction counter 31 are synchronized with the cycle of energization and de-energization of the solenoid and with a certain time delay.
However, activation and deactivation may be repeated periodically. The delay time in this case is the launch ball sensor 21 at the end of the guide rail from when the game ball is launched from the launching device 9.
It is the time to reach the position of a.

As yet another method, the launching device 9 is provided with a micro switch which is turned on when the player operates the hit ball handle 5. While the switch is on, the launch ball sensor and the counter are activated. Good.

It is also conceivable that a fraudulent player may strike the launching device 9 idle and act fraudulently on the launch ball sensors 21a, 21b with a magnet or the like. Therefore, in the configuration shown in FIG. 5, when the game ball P is not detected at the launch position, the launch device 9 is prevented from operating. In this way, the above-mentioned fraud can be prevented by the detection operation linked to the operation of the launching device 9.

Next, the electric circuit section of the embodiment will be described.

As shown in FIG. 7, an addition / subtraction counter 31 which receives detection signals from the above-mentioned launch ball sensor 14 and return ball sensor 17 is provided as a launch ball counting means for counting the number of launch balls. The addition / subtraction counter 31 has a launch ball sensor 14 for a game ball P.
When the return sphere sensor 17 detects the return sphere P ', the count value is incremented by one, and the count value is decremented by one. As a result, the number of return balls can be excluded from the number of launch balls emitted from the launching device 9, and the number of launch balls that have actually reached the game board surface 2 can be counted.

On the other hand, a winning ball sensor 32 is provided as a winning ball detecting means for detecting a game ball (winning ball) that has entered the variable winning device 3. The winning ball sensor 32 is composed of a magnetic sensor having a hole through which the game ball passes, and detects the winning ball from the change in the magnetic field when the winning ball coming out of the variable winning device 3 passes through the hole.
Of course, a sensor (optical sensor, micro switch, etc.) other than the magnetic sensor may be used. The detection signal from the winning ball sensor 32 is input to the winning ball counter 33, where the number of winning balls is counted.

The number of shot balls and prize balls counted as described above is input to the control means 34. As described above, the control means 34 carries out the conversion drive of the variable winning a prize device 3 during the game, but the variable winning a prize device 3 in which a predetermined number of game balls are present by the time the number of shot balls reaches the predetermined number. When the player wins, the variable winning device 3 that is being converted and driven is stopped in the first state, which is disadvantageous to the player.

Specifically, the control means 34 determines the number of launch balls that have reached the game board surface 2 from the output of the addition / subtraction counter 31, and based on the determination result and the detection signal from the winning ball counter 33, the variable winning device 3 Outputs a signal for controlling the conversion drive of the. The control means 34 and the counting means for counting the above-mentioned shot balls and winning balls can be integrated into one microcomputer.

The control signal from the control means 34 is input to the winning device driving circuit 35, and is output from this circuit as a signal for driving or stopping the solenoid 44 of the variable winning device 3.

In addition, the winning rate for the variable winning device 3 can be arbitrarily set by changing the number of shot balls that form one segment and the number of winning balls that the variable winning device receives during one segment. Therefore, the control unit 34 preferably includes a setting device including a plurality of key input units for inputting numbers and the like and a storage unit for storing the input data.

Next, in order to prevent illegal input to the launch ball sensors 21a, 21b in the embodiment of FIG. 4, when the detection signal from the launch ball sensor 21a or 21b is accepted while the launching device 9 is operating, As shown in FIG. 8, a signal indicating that the launching device is operating is input to the addition / subtraction counter 31, and the addition / subtraction counter 31 performs addition / subtraction according to the detection signals from the launch ball sensors 21a and 21b only while the signal is input. To configure. In this case, the signal indicating that the launching device is operating can be output from the drive circuit 36 that drives the solenoid of the launching device 9 in response to the ball hitting handle operation by the player, as shown in FIG. 9, for example.

Furthermore, the drive circuit 36 is configured to supply the solenoid drive current to the launching device 9 only when the launch ball sensor 22 shown in FIG. Can perform a function.

According to the above-described embodiment, during the game, the variable winning device 3 is alternately driven by the control means 34 into two states (a first state in which the game ball is difficult to win and a second state in which the game ball is easy to win). Then, when a predetermined number of game balls are won in any of the plurality of variable winning devices during the above-mentioned one division, the variable winning device 3 during conversion driving is stopped in the first state. If a predetermined number of game balls are not won during one division, the next one division is credited. Thus, the players are given equal opportunity to win the prize, and it is possible to comprehensively manage the prize ratio in the playground without the conventional nail adjustment.

Although the embodiments have been described above, the present invention is not limited to pachinko game machines, but can be applied to smart ball machines, sparrow ball game machines, and other ball game machines. Further, the variable winning device may use a driving means other than a solenoid. The configurations of the control means and the drive circuit can be designed arbitrarily.

[Effects of the Invention] Since the ball game machine of the present invention is configured as described above, it is possible to arbitrarily set the winning rate of the hit ball with respect to the variable winning device. As a result, there is an effect that the conventional delicate nail adjustment is not necessary and the player is equally given the chance of winning the prize.

Further, by activating the launch ball detecting means or the launch ball counting means only while the launching device is operating, or by not launching the launching device when the launch ball detecting means arranged at the launch position does not output a detection signal, It is possible to prevent cheating on a ball game machine.

Furthermore, when there are a plurality of variable winning devices, all of them are converted into two states at once, or each of them is sequentially converted into two states, so that the player can easily recognize the conversion driving of the variable winning devices, or The visual effect of conversion driving can be improved.
