Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pinball game machine such as a pachinko game machine or a coin game machine that plays the game by hitting a ball. It includes a gaming area, and a gaming device that operates in accordance with the falling trajectory of a ball hit into the gaming area and provides a state in which a predetermined gaming value can be awarded, thereby bringing about a state of profit for the player, The present invention relates to a pinball game machine that performs feedback control over the operating state of the game machine.

[Prior Art] This kind of pinball game machine has been generally known for a long time, for example,
There was one described in Publication No. 141736 and one described in Japanese Patent Application Laid-open No. 1983-91834. This conventional pinball game machine is set as a goal so that the pinball game machine takes a value based on the ratio (profit rate) of profit information that is profitable to the player and disadvantageous information that is disadvantageous to the player. The target ratio is configured to be variably settable, and the pinball game machine performs feedback so that the actual ratio between the profit information and the disadvantage information of the pinball game machine during the game approaches the variably set target ratio. It was controlled. With this configuration, the profit margin of the pinball game machine can be controlled as desired by the game hall without making many adjustments that require skill by simply variably setting the target ratio to a desired value. there was.

[Problems to be solved by the invention] However, in this type of conventional pinball game machine,
If the actual ratio of the pinball game machine deviates even slightly from the set target ratio, feedback control is immediately activated to bring the actual ratio closer to the target ratio, resulting in a so-called slump that is unique to pinball game machines. In addition, even if a player with good gaming skills plays a game, or a beginner whose gaming skills are not very good plays a game, the profit rate will be uniformly the set target ratio. Since the game is feedback-controlled, it has the disadvantage that it becomes an uninteresting pinball game machine in which there is no surprise in the game due to slump, etc., and the skill of the player's game technique is not reflected at all.

In view of these circumstances, the present invention has been developed to take advantage of feedback control, which allows the game value grant rate to be easily adjusted without requiring much skilled work such as nail adjustment, while at the same time preventing surprises in the game due to slumps and the like. To provide a pinball game machine in which the skill of a player's gaming technique can be reflected to a certain extent.

[Means for Solving the Problems] The present invention provides a state in which a predetermined game value can be given by operating according to the game area into which a ball is hit and the falling trajectory of the ball hit into the game area. In a pinball game machine that includes a game device that brings about a state that is profitable to the player, and that controls the operating state of the game device by feedback, there is a method for detecting profit information for detecting information that is profitable for the player. a means for detecting disadvantageous information for detecting information that is disadvantageous to the player; and a target for the pinball game machine to take a value based on the ratio of the advantageous information to the disadvantageous information. A target ratio variable setting means in which a target ratio can be variably set; a non-control area in which the feedback control is not performed is determined based on the variable setting by the target ratio variable setting means; If the actual ratio of profit information and disadvantage information calculated based on the output from the profit information detection means is within the non-control region, feedback control of the operating state of the gaming machine is not performed; The present invention is characterized in that it includes a drive control means for feedback-controlling the gaming machine in a direction to bring the actual ratio closer to the target ratio when the actual ratio goes outside the non-control area.

[Function] According to the present invention, the gaming device brings about a state in which a predetermined gaming value can be awarded according to the falling trajectory of the hit ball, thereby bringing about a state that benefits the player.
Further, by the function of the target ratio variable setting means, a target is given so that the pinball game machine takes a value based on the ratio of information that is beneficial to the player and information that is disadvantageous to the player. The target ratio can be set variably. Furthermore, a non-control area in which the feedback control is not performed is determined based on the variable setting by the target ratio variable setting means, and is calculated based on the output from the profit information detection means and the output from the disadvantage information detection means. If the actual ratio between profit information and disadvantage information is within the non-control area, feedback control of the operating state of the gaming machine is not performed, and the actual ratio is outside the non-control area. In this case, the gaming machine is feedback-controlled in a direction that brings the actual ratio closer to the target ratio.

In other words, the pinball game machine can be set to achieve the profit rate desired by the game hall without making many adjustments that require skill, and since there is a non-control area where no feedback control is performed, Within this uncontrolled area, a so-called slump may occur or a player may demonstrate his or her own gaming skills.

In addition, if necessary, a guide display board 15 may be provided to indicate the combination of identification information of the variable display members 6a to 6c with defined conditions for opening (or opening/closing) the Yakumono or to explain the game method. may be placed.

FIG. 2 is an illustrative view of back parts arranged on the back side of the game board of the pachinko game machine 10. In the figure,
On the back side of the game board 1 of the pachinko game machine 10, paths 211 to 215 are formed to guide the pachinko balls that have won into the Yakumono 3a to 3e downward, and the pachinko balls guided downward through the respective paths are A path 216 leading to the winning ball processing device 23 is formed.

When the pachinko ball is guided to the socket 233 via the path 216, when the pachinko ball rides on the socket 233 and rotates the cylinder member 231 downward by its own weight, the rotation of the cylinder member 231 Therefore, the winning ball detection switch 234 is pressed and activated. When this winning ball detection switch 234 detects one winning ball, the winning ball detection output is given as a signal to a prize ball payout mechanism (not shown) to command a certain number of prize balls to be paid out, and as an example of game media. A predetermined number of prize balls are paid out and game value is awarded. The variable winning ball devices 3a to 3e (including a variable winning ball device 370 to be described later) operate according to the falling path of the ball hit into the game area, so that a predetermined game value can be given. A gaming machine is configured that brings about a state of benefit to the player. After the prize ball is paid out, the socket 2

This electric ball hitting mechanism 24 includes a motor 241 that is rotationally driven by the pressure of the ball hitting switch 131, and a ball hitting cam 242 that is rotationally driven by the rotational force of the motor 241 to bias the ball hitting rod 243. a lever 244 whose one end is fixed to the ball-striking rod 243 and whose other end is formed with a pin capable of engaging with a ball-striking cam; The spring 245 is used to vary the tension of the spring 245 to change the strength of the ball hit. When the ball-striking cam 242 is rotated by the rotational force of the motor 241, the arc-shaped portion of the ball-striking cam 242 and the pin of the lever 244 come into contact and disengage, thereby causing the ball-striking rod 243 to rotate intermittently. , thereby hitting pachinko balls with electric power. Although the illustration shows the case of an electric ball hitting mechanism, a ball hitting lever connected to the ball hitting rod 243 is provided on the front, and the player can manually hit one pachinko ball one by one by flicking the ball hitting lever with his or her finger. Needless to say, it may be a manual ball hitting mechanism that hits the ball.

FIG. 3A is a detailed diagram of the variable winning ball device and the opening mechanism for opening the variable winning ball device. In the figure, a variable winning ball device (yakumono; commonly known as a tulip) 3 has a beak-shaped part (commonly known as a tulip petal) 311 to receive pachinko balls falling along the board, and is fixed to a plate 312 to play pachinko. It is placed on the board of the gaming machine. A lever 313 is provided in connection with this beak-shaped portion 311 for guiding the winning ball to the back surface of the game board. This lever 31

In addition, although the illustration explains the relationship between one set of variable winning ball devices and the opening mechanism, in the state shown in FIG. 3a to 3e and opening mechanism 30
They are shown in correspondence with a to 30e. In addition, in the illustration,
A case will be described in which an opening mechanism is provided corresponding to each of the variable winning ball devices 3a to 3e, and the corresponding opening mechanisms individually open the Yakumono, but as another example, one opening mechanism may be used to It may be something that commonly cultivates Yakumono of the group. For example, a first opening mechanism that commonly opens the Yakumono 3a to 3c, and a first opening mechanism that commonly opens the Yakumono 3a to 3c;
A second opening mechanism may be provided that opens d and 3e in common, and the opening of the Yakumono may be controlled for each of a plurality of groups by driving the first opening mechanism or the second opening mechanism.

Although we have described the case of a tulip as the variable winning ball device, the first state in which pachinko balls are easy to win, the first state that is advantageous for the player, and the first state that is disadvantageous for players who are difficult to win or are unable to win. Any other variable winning ball device may be used as long as it can be changed to the second state.

FIG. 3B is an illustrative view of another example of the variable winning ball device, in which the plate is opened forward to make it easier to win the pachinko balls. The structure of another example of the variable prize winning ball device 370 will be described with reference to the drawings. A plate 372 that can be opened toward the front of the game board is rotatably supported on a frame member 371. A pachinko ball receiving portion 373 in which pachinko balls can be won is formed on the upper part of the frame member 371.
A lever 374 is fixed to the plate 372, and by pulling the lever 374 upward, the plate 372 is opened forward. One end of a lever 375 is engaged with this lever 374, and the other end of the lever 375 is pivoted at a fulcrum 376. A portion of one end of this lever 375 is connected to a plunger 379 of a solenoid 378 via a lever 377.

And when solenoid 378 is energized,
By suctioning the plunger 379 and rotating the lever 375 upward via the lever 377,
Lever 37 engaged with one end of lever 375
4 and push the plate 372 forward of the game board to open it. In addition, solenoid 3
The opening time of the variable winning ball device 370 can be controlled by the energizing time 78. In addition, by intermittently energizing the solenoid 378, the winning ball device 370 can be changed depending on the number of times the solenoid 378 is energized.
The number of openings can be controlled. A first state is advantageous for players who are likely to win pachinko balls when the plate 327 is open, and a second state is disadvantageous for players who are unable to win pachinko balls when the plate 327 is closed. state.

In addition, as yet another example of the variable winning ball device,
A rotatable disk with one or more safe holes formed on the board is arranged on the game board, and if you want to make it easier to win pachinko balls, turn the entrance of the safe hole upwards. The rotational position of the disc is determined so as to receive the falling pachinko ball, and if it is difficult to win a prize, the disc may be rotated so that the entrance of the safe hole faces downward or sideways. .

In short, in both the variable winning ball device shown in FIGS. 3A and 3B and the disk-shaped variable winning ball device, a predetermined number of prize balls are paid out when a pachinko ball wins, and one It includes a passage area set such that a fixed number of prize balls are paid out in response to the passage of winning balls.

FIG. 4A is a diagram of a control circuit for controlling the variable winning ball device, and FIG. 4B is a specific circuit diagram of an example of the variable pulse generation circuit 41. In terms of configuration, this embodiment basically includes a variable pulse generation circuit 41 that generates a pulse for varying the opening/closing cycle of the Yakumono, a winning rate variable setting means 42, an arithmetic processing device 90, and the Yakumono 3a to 3A. 3
A frequency divider 4 is used as a control circuit for driving the opening and closing of e.
3a to 43e, differentiating circuits 44a to 44e, monostable multi 45a to 45e, AND gates 46a to 4
6e, pulse oscillation circuit 47, transistor 48a
48e, and the solenoids 32a to 32e. The frequency dividers 43a to 43e each have a different frequency division ratio, and for example, make it easier for pachinko balls to enter the jackpots 3a and 3c provided on both sides of the pachinko machine, and to make it easier for pachinko balls to enter the jackpots 3b in the center. Make it difficult to remove the two yakumono 3
If the winning probability for d and 3e is somewhere between them,
The frequency division ratio of the frequency divider 43b is selected to be a relatively large value (for example, 1/20), the frequency division ratio of the frequency dividers 43a and 43c is selected to be a relatively small value (for example, 1/10),
The frequency division ratios of the frequency dividers 43d and 43e are selected to be a medium value (for example, 1/16).

FIG. 5 is a waveform diagram for explaining the operation of FIGS. 4A and 4B, and in particular, (a) shows the output pulse p1 of the variable pulse generation circuit 41, and (b)
shows the output pulse q of the frequency divider 43a, (c) shows the output pulse r of the monostable multi 45a, (d) shows the output pulse p2 of the pulse oscillation circuit 47, and (e) shows the output pulse of the AND gate 46a. The output pulse s is shown. Next, with reference to Figures 1 to 5,
The operation will be explained along with the specific circuit configurations shown in FIGS. A and 4B.

The variable pulse generating circuit 41 changes the period of the output pulse or the ratio between the high level and the low level based on the winning rate setting of the winning rate variable setting means 42 in order to vary the cycle of driving the opening/closing of the beak of the Yakumono. It generates pulses with variable duty ratios. This variable pulse generation circuit 4
1, for example, an unstable multivibrator (hereinafter referred to as an unstable multivibrator) as shown in FIG. 4B is used. The generally known unstable multi is
The base ends of the transistors T1, T2 are cascade-coupled via capacitors C2, C1 and connected to the collectors of the other transistors T2, T1, and the collectors of the transistors T1, T2 and the power supply (+
E), and the frequency (or duty ratio) of the output pulse is determined by the time constant of the resistance value of the resistor and the capacitance of the capacitor. By the way, the astable multiplier used in this embodiment has resistors R11 and R1 connected between the collector of one transistor T1 and the power supply (+E).
2. R13 can be switched by contacts 421, 422, and 423, which are an example of the winning rate variable setting means 42, and the resistance values of resistors R11, R12, and R13 are made different (for example, the resistance value of R11 is large, the resistance value of R12 is is medium and R13 is small), the selected resistor R11, R1
2. By making it possible to switch the time constant determined by the resistance value of R13 and the capacitance of the capacitor C1, the frequency (or duty ratio) of the output pulse can be varied. This winning rate variable setting means 42 includes, for example, each contact 421, 422,
423 is a manual switch, placed on the back of the game board, and manually set as appropriate before the store opens, or each manual switch is placed in a monitoring room where an attendant is present, and the manual switch is placed on the back of the game board. You can select and set the settings as appropriate. When the contact 421 is closed and the resistor R11 with the largest resistance value is selected, the time constant becomes the largest, the frequency of the output pulse becomes lower, and the period of driving the opening and closing of the Yakumono becomes slower. , the winning rate is set to be the lowest. Further, by closing the contact 422 and selecting the resistor R12 having a medium resistance value, the winning rate is set to be medium. Also, when the contact 423 is closed and the resistor R13 with the lowest resistance value is selected, the time constant becomes smaller and the frequency of the output pulse becomes higher, and therefore the cycle of opening and closing the Yakumono becomes faster, so you can win a prize. The rate is set to be high.

In addition, in the above explanation, for convenience of explanation, we have described the case where the winning rate can be switched to 3 stages, but if you want to widen the variable setting range, the stage should be configured to be switchable to 4 or more stages. Bye.

By the way, the profit margin such as the ball output rate, which is calculated by the ratio of the number of balls hit and the amount of game value given such as the number of prize balls (number of prize balls / number of balls hit), is the amount of game value given such as the number of prize balls etc. is calculated by the product of the number of winning pitches and the number of pitches paid out in response to one winning pitch, so it is correlated to the winning rate (number of winning pitches/number of batted pitches). As aforementioned,
If the winning rate is variably set by switching the contacts 421, 422, and 423, the winning rate can be variably set based on the above correlation.

Note that each contact 421 of the variable setting means 42,
Relay contacts 422 and 423 may be used to remotely and automatically switch based on the gaming state, as will be explained later with reference to FIG. Furthermore, as another example of the winning rate variable setting means 42, the resistor R1
1 to R13 and contacts 421 to 423,
A variable resistor may be inserted between the collector of the transistor T1 and the power supply (+E), so that the frequency of the output pulse can be varied over a wide range with the variable resistor.

Further, as the variable pulse generation circuit 41,
Various other variations are possible. For example, the oscillation output period may be varied by making the control voltage of the voltage controlled oscillation circuit variable by the output of the winning rate variable setting means. Alternatively, a rectangular wave oscillation circuit and a level discrimination circuit may be provided, and the threshold value of the level discrimination circuit may be varied based on the output of the winning rate variable setting means. Furthermore, the frequency division ratio of the output pulse of the pulse oscillation circuit may be configured to be switchable.

Next, the operation will be described assuming that the contact 422 included in the winning rate variable setting means 42 is closed and the resistor R12 is selected. The variable pulse generating circuit 41 generates a pulse p1 of a medium constant period (T1) and provides it as an input to the frequency dividers 43a to 43e. For example, if the frequency divider 43a divides the output pulse p1 into 1/10, the frequency divider 43a divides the output pulse p1 into 1/10 as shown in FIG. 5b.
A high level (hereinafter referred to as "H") signal and a low level (hereinafter referred to as "L") signal are alternately derived for every 10 signals and applied to the differentiating circuit 44a. Differential circuit 44
a differentiates the frequency-divided pulse q at the rising edge and gives it as an operation command signal to the monostable multi 45a. depending on,
The monostable multi 45a derives the output r of the "H" signal for a predetermined period of time, and outputs the "H" signal r for a predetermined period of time, and outputs the output r of the AND gate 46a.
Give it as one input. By the way, in the normal state, the pulse oscillation circuit 47 operates within the time required to open and close the beak of the yakumono once (for example, 0.5~
The AND gate 46a generates a pulse p2 with a period (T2) such that one pulse is generated every 1 second).
~46e is given as the other input. Therefore, the AND gate 41a derives the output pulse p2 of the pulse oscillation circuit 47 during the period in which the output pulse r of the monostable multi 45a is given, and supplies the output pulse s to the transistor 48a for the number of output pulses s. The transistor 48a is made conductive intermittently. This causes the solenoid 32a to
The number of output pulses of the AND gate 46a (4 in the figure)
The energization is intermittently controlled by the number of output pulses s, thereby repeatedly driving the beak-shaped portion 311 of the yakumono 3a to open and close by the number of output pulses s.

Similarly, the other frequency dividers 43b to 43e each divide the output pulse p1 of the variable pulse generation circuit 41 at a predetermined frequency division ratio, and each divided pulse is outputted by the corresponding differentiating circuit 44b to 44e. It is differentiated and applied to monostable multis 45b to 45e, and while each monostable multis 45b to 45e derives an "H" signal for a certain period of time, each AND gate 46b to 46e
derives the output pulse p2 of the pulse oscillation circuit 47 to intermittently conduct the corresponding transistors 48b to 48e (that is, repeatedly turn them on and off),
As a result, each of the solenoids 32b to 32e is intermittently energized to repeatedly open and close the beak-like portions of each of the yakumono 3b to 3e. As mentioned above, the frequency division ratio of each frequency divider 43a to 43e is selected to be a different frequency division ratio depending on the installation position of the corresponding Yakumono whose opening/closing is to be controlled.
The repetition period at which the gate e is driven to open and close becomes different.

Next, a case will be described in which the payout rate (winning rate) is varied by the switching setting of the input prize rate variable setting means 42. For example, even though the contact point 422 is closed as described above and a medium payout rate is set, due to the nail adjustment being good or the player's skill being excellent, the ball stop control may not be performed. If you want to open the pachinko machine to other players after you have mastered it,
The staff member opens the manual switch (contact) 422 provided on the back of the game board and then switches the manual switch 421.
or remotely operated from the monitoring room to open contacts 422 and close contacts 421. Additionally, if a player wants to reduce the ball payout rate remotely from the monitoring room because the pachinko machine has a good ball payout rate while the player is playing pachinko, the staff member can operate the contact point 422 remotely from the monitoring room. Open and close contact 421. As a result, the variable pulse generation circuit 41 has a large time constant determined by the resistor R11 and the capacitor C1, so the output pulse p
1 frequency. Variable pulse generation circuit 4
As the frequency of the output pulse p1 of 1 is lowered, the period of the divided pulse output from the frequency divider 43a is delayed, and therefore the "H" of the monostable multi 45a is delayed.
The appearance phase (period) of the signal is delayed. At this time, since the output frequency of the pulse oscillation circuit 47 and the "H" signal period (t) of the monostable multi 45a are constant, the number of opening/closing cycles of the Yakumono 3a is a constant number (four times in the waveform diagram of FIG. 5). However, since the appearance phase of the "H" signal of the monostable multi 45a is delayed, the total opening time of the Yakumono 3a becomes shorter than when the contact 422 is closed. Therefore, the probability that the hit pachinko ball will land in the Yakumono 3a is reduced, and the ball output rate is controlled to be reduced. It should be noted that the winning rates for the other Yakumono 3b to 3e are similarly reduced.

On the other hand, when changing the settings to increase the winning rate, the frequency of the output pulse of the variable pulse generation circuit 41 can be changed by manually or remotely opening the contact 422 and closing the contact 423. As a result, the "H" signal appearance cycle of the outputs of monostable multi 45a to 45e becomes faster, and Yakumono 3a to 3
The total opening time of e becomes longer than when the contact 422 is closed. Therefore, the probability that a hit pachinko ball will win a prize in the Yakumono 3a to 3e increases, and control is performed to increase the ball output rate.

As mentioned above, in the embodiments shown in FIGS. 4A and 4B, the ball payout rate (winning rate) can be varied with an extremely simple operation without adjusting the angle or spacing of the nails formed on the game board. This has the advantage that even non-experts can adjust the ball payout rate. In addition, the contact points included in the winning rate variable setting means can be switched remotely, which has the advantage that the ball payout rate can be easily changed even when the game parlor is open. In addition, since the Yakumono are repeatedly opened and closed individually or in groups, the probability of winning a Yakumono can be improved regardless of whether there are winning conditions for other safe holes, etc., and the service to players can be improved. There are advantages that can be achieved. Furthermore, since each Yakumono is repeatedly opened and closed for a certain unit time, there is an advantage that it is easy to attract the attention of the players and it is possible to increase the interest of the players.

In addition, in the above-mentioned embodiment, a case was explained in which a plurality of Yakumono were individually and intermittently repeatedly driven to open and close at a certain irregular period.
Only one winning ball device at a predetermined position may be repeatedly driven to open and close.

As a modification of the drive control means shown in FIG. 4A, when the Yakumono 3a and 3b are grouped and repeatedly driven to open and close, the frequency divider 43b and the differential circuit 4
4b, without providing monostable multi 45b,
Monostable multi-4 is connected to the other input of AND gate 46b.
The circuit may be connected to provide the output of 5a.
Similarly, when the Yakumono 3d and 3e are grouped and driven to open and close repeatedly, the output of the monostable multi 45d is sent to the AND gate 4 without providing the frequency divider 43e, the differentiation circuit 44e, and the monostable multi 45e.
The circuit may be connected so as to provide it as the other input of 6e. As another modification, if you want to make the number of times each Yakumono is repeatedly opened and closed different, you can choose to make the "H" signal derivation periods (i.e., time constants) of the monostable multis 45a to 45e different. . Furthermore, as another variation,
If it is desired to equalize the period of repeatedly opening and closing the beak-like part of the yakumono and the period of rest of the repetitive opening and closing operation, the circuit is designed so that the output of each frequency divider 43a to 43e is directly given as the other input of the corresponding AND gate 46a to 46e. Just configure it. In addition, the frequency divider 43a
43e may be replaced with an N-ary counter that generates a pulse every time a different predetermined number is counted.

Furthermore, if the pachinko game machine has an electric ball striking mechanism, each machine is repeatedly opened and closed for a certain unit period only when a player is playing the game, and repeatedly opened and closed when no player is present. If you want to stop it, use each AND gate 46a~
The pressing output of the ball hitting switch is set to each AND gate 46a so that the pressing of the ball hitting switch 131 is a condition for deriving the output of the ball hitting switch 46e.
~46e may be commonly given. By doing this, it is possible to prevent the solenoids 32a to 32e from being energized when no player is present.
This has the advantage of preventing solenoid burnout and extending the life of the solenoid.

Furthermore, if you want to open and close a plurality of yakumono irregularly and repeatedly based on a certain gaming state during a pachinko game, you can do as follows. For example, the plurality of variable display members 6
If the Yakumono can be driven repeatedly to open and close when the combination of identification information displayed on a, 6b, and 6c becomes a predetermined combination, it is possible to detect the display state of the variable display members 6a, 6b, and 6c. It is determined whether or not a predetermined combination has been obtained, and when the predetermined combination has been obtained, the AND gate 46
The circuit may be configured so that a to 46e are activated.

FIG. 6 is a circuit diagram showing another example of the drive control means explained in FIG. 4A. In addition, the above-mentioned 4A
The same parts as in FIGS. 4B and 4B are designated by the same reference numerals.
FIG. 7 is a waveform diagram of each part for explaining the operation of FIG. 6. Next, the detailed structure and operation of the preferred embodiment will be explained with reference to FIGS. 6 and 7.

The variable pulse generating circuit 61 is, for example, as shown in FIG. 7a.
As shown in , the “H” signal period is short and the “L” signal period is short.
It generates a pulse p3 with a long signal period and a variable period "T3", and the "H"
The signal period is chosen to be the time required to energize the solenoid to open the trigger. Specifically, the variable pulse generation circuit 61 uses a circuit as shown in FIG. 4B described above.
The resistor R11 is set so that the signal period meets the above conditions.
~Resistance value of either R13 and capacitor C
1 capacitance, resistance value of resistor R3, and capacitor C
In addition, the resistance values of the resistors R11, R12, and R13 are determined so that the cycle T3 (ie, frequency) can be varied in order to vary the winning rate. The output pulse p3 of the variable pulse generation circuit 61 is given as one input to the AND gates 46a to 46e, and is given as an inhibit input to the AND gate 631.
It is given as one input to AND gates 632 and 633. On the other hand, the pulse oscillation circuit 62 generates a pulse p4 (pulse with period T4; see FIG. 7b) having a higher constant frequency than p3, and AND
Provided as one input to gate 631. this
The output of an OR gate 634, which will be described later, is inverted and applied to the other input of the AND gate 631 as an inhibit input. The AND gate 631 derives the output pulse p4 of the pulse oscillation circuit 62 as the output pulse p5 (see FIG. 7c) during the period when the pulse p3 is an "L" signal and the output of the OR gate 634 is an "L" signal, The pulse p5 is given to the ring counter 64. This ring counter 64 increments the count every time a pulse p5 is input, and cyclically counts by a number corresponding to the number of the variable winning ball devices 3a to 3e, and the count value is 1 to 5. It has a corresponding output terminal, and an "H" signal is derived from the output terminal corresponding to the count value. The outputs ("H" signals) derived from the respective output terminals corresponding to the numbers 1 to 5 of the ring counter 64 are given as the other inputs of the AND gates 46a to 46e via the corresponding OR gates 65a to 65e. .

For example, as shown in the waveform diagram shown in FIG. 7, when one pulse is derived from the pulse oscillation circuit 62, the AND gate 631 supplies one pulse to the ring counter 64. Ring counter 6 accordingly
When the output pulse p3 of the variable pulse generation circuit 61 becomes an "H" signal while the output pulse 4 is counting the value 1, the AND gate 631 does not derive the output pulse of the pulse oscillation circuit 62 during that period. Therefore, the ring counter 64 maintains the state of counting the number 1, derives the "H" signal pulse m1 from the output terminal corresponding to the number 1, and supplies it to the AND gate 46a via the OR gate 65a. At this time,
Since the AND gate 46a is given the pulse p3, the AND gate 46a outputs the output pulse s.
1 is derived, and the transistor 48a is made conductive.
This energizes the solenoid 32a, and during the "H" signal period of the pulse p3, the variable winning ball device 3a
will be opened. Then, when the pulse p3 is reversed to the "L" signal, the solenoid 32a is deenergized, so the variable winning ball device 3a is closed. As a result, the variable winning ball device 3a is driven to open and close only once.

Further, when the output pulse p3 of the variable pulse generation circuit 61 is inverted to an "L" signal, the AND gate 631 derives the pulse p4 output from the pulse oscillation circuit 62 as the output pulse p5, and the ring counter 6
Give to 4. Therefore, the ring counter 64 sequentially increments its count value one by one in synchronization with the output pulse p4 of the pulse oscillation circuit 62, and outputs pulses m2, m3, m4,
m5 is derived, but at this time pulse p3 is "L"
Since it is a signal, neither solenoid is energized, and therefore neither variable winning ball device 3a
~3e is also not opened. In addition, as shown in Figure 7
Below the waveform of the output pulse p5 of the AND gate 631, for ease of understanding, the count value of the ring counter 64 when the pulses p5 are sequentially applied is shown.

As described above, each time the AND gate 631 derives the output pulse p5, the ring counter 6
4 cyclically increments the count value, but when the output pulse p3 of the variable pulse generation circuit 61 is inverted to the "H" signal, the AND gate 6
31 is prohibited, and an output pulse m5 corresponding to the count value (for example, 5) counted by the ring counter 64 immediately before is applied to the AND gate 46e via the OR gate 65e. For this reason,
The AND gate 46e derives an output pulse s5 and makes the transistor 48e conductive, so that the solenoid 32
energize e. As a result, during the "H" signal period of the pulse p3, the variable winning ball device 3e is opened, and when the signal is reversed to "L", the variable winning ball device 3e is closed. Therefore, as a result, the variable winning ball device 3e is driven to open and close only once.

Similarly, at the timing when the pulse p3 is an "H" signal, one of the variable winning ball devices sequentially selected by the count value of the ring counter 64 is driven to open and close, but the operation is as explained above. Since it can be easily understood by referring to Figure 7,
The explanation will be omitted.

In this way, in the embodiment shown in FIG. 6, the error is detected at the timing determined by the combination of the cyclic count value of the ring counter 64 and the "H" signal output period of the output pulse p3 of the variable pulse generation circuit 61. The opening of any one of the variable winning ball devices 3a to 3e is controlled regularly.

By the way, in this embodiment as well, the above-mentioned fourth
In the same way as in Figures A and 4B, resistor R1
The period T3 of the output pulse p3 of the variable pulse generation circuit 61 is determined by switching any one of 1, R12, and R13.
(or the frequency), the appearance phase (period) of the "H" signal of the output pulse p3 can be made slower or faster. For this reason,
The total opening time of the variable winning ball devices 3a to 3e can be shortened or lengthened, thereby making it possible to variably set the winning rate (ball output rate).

In addition, when it is desired to group a plurality of variable winning ball devices based on the pachinko gaming state (for example, the combination state of the identification information displayed on the variable display members 6a, 6b, and 6c) and to open and close them intermittently and repeatedly. can be done as follows. That is, the passage areas 2a, 2b, 2 shown in FIG.
Each time a pachinko ball passes through c, the identification information of the corresponding variable display members 6a, 6b, 6c is variably controlled, and each variable display member 6a, 6b, 6c
The game state detection means 66 is configured to detect a combination of identification information. When this game state detection means 66 detects a combination of identification information of the predetermined variable display members 6a, 6b, 6c that can open the three variable winning ball devices 3a to 3c, it derives an "H" signal. Set the flip-flop (FF) 671. This set output is AND gate 63
2 as the other input, and also as the inhibit input of AND gate 631 via OR gate 634. Therefore, when the gaming state detection means 66 detects a certain gaming state, the counting operation of the ring counter 64 is stopped. Then, each time the pulse p3 becomes an "H" signal, the AND gate 6
32 derives the pulse p3 and sends it to the OR gate 65
It is provided as the other input of the corresponding AND gate 46a, 46b, 46c via the gates a, 65b, and 65c. Accordingly, AND gates 46a, 46b, 46
c makes the corresponding transistors 48a, 48b, 48c conductive during the "H" signal period of the pulse p3 to control the energization of the solenoids 32a, 32b, 32c, thereby controlling the three variable winning ball devices 3.
A, 3b, and 3c are driven to open and close. At this time,
The output pulse of AND gate 632 is the output pulse of OR gate 63
5 to an N-ary counter 68. Therefore, when the three variable winning ball devices 3a, 3b, and 3c grouped a predetermined number of times (for example, 5 times) are simultaneously driven to open and close, the N-ary counter 68 derives a count-up output. TeFF
671 is reset. As a result, when the gaming state reaches a predetermined condition, the plurality of grouped variable prize winning ball devices are driven to open and close.

In addition, when the gaming state detection means 66 detects a condition that allows the two variable winning ball devices 3d and 3e to be opened and closed, the FF 672 is set and the AND gate 6
33 to derive pulse p3 and OR gate 6
By providing one of the inputs 5d and 65e, the two variable winning ball devices 3d and 3e are driven to open and close.

Note that in the above explanation, the variable pulse generation circuit 4
We have described cases in which the output frequency of 1 or 61 is switched manually or by remote control by a staff member, but information on the number of profitable balls (number of winning balls, prize balls, or supply The number of pitches) and information on the number of disadvantageous pitches (number of batted balls or number of out balls) that is disadvantageous to the player (that is, the profit to the amusement park operator) and the relationship (for example, the number of profitable pitches and the number of disadvantageous pitches) The output frequency of the variable pulse generation circuits 41 and 61 may be automatically variably controlled by the winning rate variable setting means based on the difference between the number and the ratio between the two. Therefore, a case will be described below in which the output frequency of the variable pulse generation circuit is automatically varied.

FIG. 8 is an illustrative view of an operation panel 80 included in the winning rate variable setting means according to a preferred embodiment of the present invention. In the figure, on the surface of the operation panel 80, 0, 1
Numerical keys 81 for inputting numerical information of ~9

A winning rate setting key 85 indicating that the winning rate is a set value, a manual stop key 86, and a setting mode key (hereinafter referred to as setting key) 87 are provided. This setting key 87 is the ball payout rate (or winning rate)
Contains keys corresponding to the number of stages in a variable configurable range. For example, assuming that the ball output rate can be set in a variable range of five stages, five setting keys 871 to 87 are used.
5 is provided. Set the setting key 871 to the lowest ball output rate (for example, 80%), and press the setting key 87
2 sets the ball payout rate to a low rate (for example, 90%),

100%), set the setting key 874 to set the ball payout rate to a high rate (for example, 110%), and press the setting key 87
5 is determined to set the ball payout rate to the highest rate (for example, 120%). In this way, when the ball output rate is varied in five stages, five contacts shown in the above-mentioned FIG. 4B are provided, and each contact point 421 to 425 is
(However, 424 and 425 are not shown) are set so as to correspond to each setting key 871 to 875.
In addition, if necessary, the operation panel 80 may include a thumb rotor switch 88 for setting the number of stops for all pachinko machines installed in the game parlor, and a numerical value entered using the numeric keys 81. A numeric display 89 for displaying information is provided.

FIG. 9 is a block diagram showing an arithmetic processing unit 90 included in the winning rate variable setting means and related parts thereof in a preferred embodiment of the present invention. In this preferred embodiment, the contacts 421 to 425 and the operation panel 80
and the arithmetic processing device 90 constitute a winning rate variable setting means that automatically variably sets the winning rate (that is, the ball output rate). Next, Figures 4B, 8 and 9
A case in which the output frequency of the variable pulse generation circuit is automatically variable controlled will be described with reference to the drawings.

For example, as mentioned above, number keys 871, 8
Ball payout rate of 72,873,874,875 is 80%90
To set it to %100%110%120%, press setting key 8.
After pressing 71 and operating the numerical key 81 to input 80, press the ball output rate setting key 84, pressing the setting key 872 and operating the numerical key 81 to input 9.
After inputting 0, press the ball output rate setting key 84, and then press each setting key 873, 874, 875 in the same manner.
Set and input the ball payout rate for each game. The ball payout rate corresponding to each setting key set in this manner is stored in a storage area corresponding to each setting key of the processing data storage memory (for example, RAM) 94.

In addition, when setting the winning rate, if 15 pachinko balls are paid out for each winning ball,
Press setting keys 871 to 875 and numeric key 8
By operating 1, the winning rate is 5.3 (%), 6 (%), 6.6 (%),
7. After entering 3 (%) and 8 (%), press the winning rate setting key 8
Just press 5. In other words, the ball payout rate is 1
The value divided by the number of balls paid out for each winning ball becomes the winning rate corresponding to the ball output rate. Said setting key 8
71-875, numeric key 81, winning rate setting key 8
5 constitutes a target winning rate variable setting means for variably setting a target winning rate given as a target so that the variable winning ball device takes that value.

When setting the ball output rate for each pachinko machine, press the machine number key 831 and operate the numerical keys 81 to enter the machine number and specify the machine for which the ball output rate should be set. Then, press the setting keys 871 to 875 corresponding to the desired ball payout rate. For example, 1
The number 3 pachinko machine's ball output rate is 100%, the number 2 pachinko machine's ball output rate is 110%, and the number 3 ball output rate is 90%.
To set it as %, press the machine number key 831 and input 1 using the numerical key 81, press the setting key 873, press the machine number key 831 and input 2 using the numerical key 81, and then press the setting key 874. Press
After pressing the machine number key 831 and inputting 3 using the numeric key 813, the setting key 872 is pressed. Thereafter, the ball payout rate is set for each machine number in the same manner. When the ball output rate for each machine number is set in this way, the calculation control unit 91 writes the ball output rate corresponding to the operated setting key as the target ball output rate in the storage area for each machine number of the RAM 94. be remembered.

By the way, each of the plurality of pachinko machines provided in the game parlor is provided with the winning ball detection switch 234 and the hit ball sensor 25, as explained in FIG. 2 above. This winning ball detection switch 234 constitutes profit information detection means for detecting information advantageous to the player. Further, the hit ball sensor 25 constitutes disadvantageous information detection means for detecting information that is disadvantageous to the player. Note that, as described above, the profit information detection means may be constituted by a switch that detects prize balls and supply balls in addition to winning balls. Furthermore, as mentioned above, the disadvantageous information detection means,
It may be configured with a sensor that detects out balls in addition to batted balls. The operation panel 80 constitutes a target ratio variable setting means that can variably set a target ratio given as a target so that the pinball game machine takes the value of the ratio of the profit information total to the disadvantage information total. ing. The operation panel 80 constitutes a grant rate variable setting means for variably setting the grant rate of the game value awarded by the gaming machine. Further, since the operation panel 80 is capable of variably setting the game value award rate, the award rate variable setting means is disposed at a position away from the pinball game machine and remotely controls the game value award rate. Includes remote control means that can variably set the value addition rate. The output of the winning ball detection switch 234 and the output of the hit ball sensor 25 for each pachinko machine are constantly input to the calculation section 92. The calculation unit 92 selects each pachinko machine in relatively high-speed time sequence, and if there is an output from the hit ball sensor 25 of the selected pachinko machine, it cumulatively counts the hit balls and outputs the winning ball detection switch 234. If there is, the number of balls paid out for each winning ball is added cumulatively to the number of prize balls up to that point (that is, the number of balls paid out for each winning ball is added to the number of winning balls as a result). (to calculate the number of prize balls), and calculate the ratio of the number of prize balls to the number of balls hit (that is, the ball output rate). Then, the calculation unit 92 repeats the operation of calculating the actual ball payout rate for each pachinko machine, and stores the ball payout rate in a ball payout rate storage memory (RAM) 93 for each machine number of the pachinko machine.

The arithmetic control unit 91 includes a program storage memory 911 and a timer 912, and operates the pachinko machine of each machine number based on the target ball payout rate for each machine number, which is preset and stored in the RAM 94, while the gaming hall is open. Set the output frequency of the variable pulse generation circuit 41 (or 61) included in the. For example, 1
The pachinko machine numbered closes the contact 423 included in the variable pulse generation circuit 41 to set a medium payout rate (100%), and the number 2 pachinko machine closes the contact 423 included in the variable pulse generation circuit 41.
Close 4 and set a high ball payout rate (110%),
The No. 3 pachinko machine closes the contact 422 and sets a low ball payout rate (90%).

Then, when the timer 912 derives a command signal to reset the ball output rate at a predetermined time, the arithmetic control unit 91 sequentially calculates the actual ball output rate for each pachinko machine stored in the RAM 93. and RAM9
4 is compared with the target ball release rate stored in 4, and it is determined which contact among contacts 421 to 425 should be switched to based on the magnitude relationship between the actual ball release rate and the target ball release rate. Specifically, the arithmetic control unit 91 determines, for example, that the actual ball payout rate of the No. 1 pachinko machine is within a certain range (for example, ±5%) of the target ball payout rate (100%).
It is judged whether the ball is above or below the above value, and if it is above the contact point 423 is opened and contact 422 is closed so that the ball payout rate is one step lower (90%), and if it is below the ball value, the contact point 423 is opened and the contact point 422 is closed. The contact 423 is opened and the contact 424 is closed so that the ball output rate is on the upper level (110%).
Thereby, it is possible to control the actual ball release rate to approach the target ball release rate. The certain range (for example, ±5%) constitutes a non-control region in which the feedback control is not performed based on the variable setting by the variable target ratio setting means. After opening the contact point 423 and closing the contact point 424, the arithmetic control unit 91 similarly compares the target ball output rate and the actual ball output rate for each machine number, and adjusts the target ball output rate to approach the target ball output rate. The contacts 421 to 425 are switched so that the ball payout rate is one level higher or lower than the current level. The arithmetic control section 91 determines a non-control area in which the feedback control is not performed based on the variable setting by the target ratio variable setting means, and outputs the output from the profit information detection means and the output from the disadvantage information detection means. If the actual ratio of profit information and disadvantage information calculated based on A drive control means is configured to perform feedback control of the gaming machine in a direction to bring the actual ratio closer to the target ratio when the actual ratio is out of the control range. Further, when the target ratio is set in the form of a winning rate by the operation panel 80, the calculation control unit 91 controls the winning rate of balls hit to the variable winning ball device. includes a winning rate control means for controlling the winning rate of balls hit into the variable winning ball device so that the actual ratio converges to the target ratio. Also,
The drive control means may control the variable display means so that the actual ratio converges to the target ratio. As a specific means for this, means such as changing the probability of establishment of a specific display state of the variable display means can be considered. Further, the control to converge to the target ratio may be performed for each pinball game machine by a microcomputer incorporated in the pinball game machine.

By the way, in pachinko game parlors, in order to know the operating status of each pachinko machine, information such as the number of batted balls, the number of prize balls, and the difference between them are always displayed.
Alternatively, the management device of the game hall is provided so that the machine number is automatically displayed when the staff in charge specifies the machine number. Therefore, the staff at the game parlor looks at the difference information for each machine displayed on the management device and determines whether the player who has won a large number of prize balls will receive the ball that has been set by the timer 912. There may be cases where it is desired to manually change the rate before the command time for resetting the rate is reached. In such a case, the staff member operates the numeric keys 81 included in the operation panel 80 to input the machine number of the pachinko machine, and then presses the machine number designation key 831 to specify the machine. Press any of the desired setting keys 871 to 875 to change the ball rate. Accordingly, the arithmetic control unit 91 closes any of the contacts 421 to 425 corresponding to the set setting key included in the winning rate variable setting means of the pachinko machine via the interface 96 and remains closed until then. By opening the contact point that was previously set, the winning rate can be automatically and remotely set.

In this embodiment, the ball payout rate (or winning rate) can be quickly set with a simple operation before the opening of the game hall, even if you are not an expert like a nailsmith, and the ball payout rate (or winning rate) can be set in advance with a simple operation before the opening of the game hall. Based on the target ball output rate and the ball output rate during actual operation, the contact points can be automatically switched and the actual ball output rate can be controlled to approach the target ball output rate, and moreover, it can be controlled remotely. It has the advantage of being able to be switched manually.

Note that the operation panel 80 and the arithmetic processing device 90
may be provided in conjunction with or integrally with a gaming hall management device for managing the operating status of each pachinko machine in the gaming parlor and controlling termination based on the operating status.

In addition, in the above-mentioned embodiment, the case where the ball output rate of a pachinko machine is variably controlled as an example of a pinball game machine has been described. It can also be applied to arranged ball type pachinko game parlors and coin game machines. For example, if the technical idea of the present invention is applied to a coin gaming machine that assigns points according to winning balls to a winning ball device and pays out valuable objects such as prizes (coins) based on the points, the winning ball device By varying the winning rate, the points that can be acquired can be remotely set, thereby making it possible to vary the prize payout rate.

[Effects of the Invention] The present invention having the above-mentioned configuration allows a pinball game machine to be set to achieve a desired profit rate without much skillful adjustment, but without the formation of an uncontrolled area. Because of this, so-called slumps do not occur within that area, and players can demonstrate their own gaming skills without losing the fun of the gaming machine.
