Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ball payout rate control device for a pachinko game machine, and more specifically, the invention relates to a ball payout rate control device for a pachinko game machine, and more specifically, a device for controlling the payout rate of pachinko balls in a pachinko game machine. In the pachinko game machine, the number of profit balls which is profitable for the player increases as the pachinko balls enter the variable winning ball device and the variable winning ball device is arranged to change into a state in which it is difficult to win. The ball payout rate based on the ratio of the number of profitable balls to the number of disadvantageous balls that is disadvantageous to the player is 1.
The present invention relates to a ball payout rate control device that independently controls a pachinko game machine.

[Prior Art] Conventionally, in general, pachinko game machines have a plurality of obstacle nails planted on the game board, and when a player drives a pachinko ball into the game board, the pachinko ball is hit by the action of the nails. The ball is configured to pay out a predetermined number of prize balls for each winning ball when the ball falls with a certain probability of changing its falling direction and wins a prize. In such pachinko machines, the rate of prize balls that come out, which is correlated to the ratio between the number of winning balls and the number of balls played (in other words, the winning rate), is determined by the spacing and angle of the many nails formed on the board. It is determined accordingly. Pachinko game parlors with a good ball payout rate are popular with players, and the number of visitors and sales of the game center are determined by the quality of the ball payout rate. However, if the ball payout rate is made too high, it is not desirable for the game hall operator to run the game in the red. Therefore, in order to allow a large number of players to enter, which is desirable for the management of the gaming hall, conventionally, after the store closes, a nail craftsman will judge the game play rate of the pachinko machine based on the ball payout rate of the day (or the ball payout rate of the previous day before the store opens). By adjusting the nails formed on the board surface, the payout rate of the pachinko machine for the next day (or the same day) was adjusted.

[Problem to be solved by the invention] However, the conventional method of adjusting the ball payout rate by adjusting the nails for each pachinko machine requires the skill of the nailer and requires a lot of time and effort. In addition to requiring labor and time, once the nails are adjusted, the nails cannot be readjusted while the amusement park is open, so there is the inconvenience that once the nails are set, the ball output rate for that day is fixed. It was hot.

In addition, as a strategy for game hall management, when a player starts playing, the ball payout rate is controlled to be relatively high so that the player can play to his or her full satisfaction, and after a certain period of time, the target ball payout rate is controlled. There is a desire among amusement centers to control the ball output rate (for example, a lower ball output rate than the initial state) to prevent the amusement center from operating in the red while giving players a certain degree of satisfaction. Ta. In addition, in some gaming parlors, contrary to the above, the ball output rate is controlled to be relatively low at the beginning of the game, and the ball output rate is controlled to be high after a certain period of time, so that players can play patiently for a long time. There was also a demand for a pachinko machine that would be more attractive to players who play pachinko by increasing the payout rate.

In other words, in gaming parlors, there was a demand to change the ball payout rate as needed during business hours, but with conventional pachinko machines, the ball payout rate for the day is fixed, so this is not possible. The drawback was that it was unable to meet the demands of amusement arcades.

In view of the above circumstances, it is an object of the present invention to make it possible to change the payout rate of a pachinko game machine from a certain desired value to another desired value as necessary during operation.

[Means for Solving the Problems] The present invention provides a variable winning ball device that can change the state in which pachinko balls hit into the game board are easy to win and the state in which it is difficult to win. In a pachinko game machine in which the number of profitable balls that is profitable for the player increases as pachinko balls enter the machine, the number of profitable balls that is profitable for the player and the number of disadvantageous balls that are disadvantageous for the player are A ball output rate control device that independently controls a ball output rate based on a ratio for one pachinko gaming machine, and a ball output rate setting that can appropriately set the ball output rate to a first value and a second value. means, switching condition detection means for detecting that a predetermined condition for switching and changing the ball output rate of the pachinko gaming machine is satisfied, and a switching condition detection unit that detects that a predetermined condition for switching the ball output rate of the pachinko gaming machine is established; The variable winning ball device is controlled so that the ball output rate of the pachinko gaming machine approaches the second value based on the detection output of the switching condition detection means from the first gaming state in which the variable winning ball device is controlled. and a winning state switching drive control means for switching the game control state to a second game state in which the winning state is controlled.

[Function] According to the present invention, the ball payout rate of the pachinko gaming machine can be appropriately set to the first value and the second value by the ball payout rate setting means in the gaming hall. Further, by the action of the winning state switching drive control means, the variable winning ball device is controlled so that the ball payout rate of the pachinko game machine approaches the first value, and the ball payout rate of the pachinko game machine is switched. Based on the establishment of a predetermined condition for the change, the variable winning ball device is controlled so that the ball payout rate of the pachinko game machine approaches the second value.

That is, initially, the variable winning ball device is controlled in a first gaming state such that the ball output rate of the pachinko game machine approaches a preset first value, and the predetermined conditions for switching the ball output rate are set. If this is established, the game control state is switched to a second game state in which the variable winning ball device is controlled so that the ball output rate of the pachinko game machine approaches a preset second value, and the pachinko game is started from the middle. The ball payout rate of the machine is changed.

[Embodiments of the Invention] Next, embodiments of the present invention will be described in detail based on the drawings.

When the player 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. Thereafter, the pachinko balls on the socket 133 are guided to the path 118 via the path 117, and the return mechanism 135
is operated to return the cylindrical member 131. In this way, winning balls are sequentially detected one by one.

In addition, on the back of the pachinko machine, Yakumono 2
Opening/closing mechanisms 20a to 20e for electrically driving opening and closing of a to 2e (described in detail in FIG. 2 below)
will be placed. Further, an electric ball hitting mechanism 14 is provided below the back surface of the game board. This electric ball hitting mechanism 14 includes a motor 141 that is rotationally driven by the pressure of a ball hitting switch (not shown) provided on the front surface of the game board, and a ball hitting rod that is rotationally driven by the rotational force of the motor 141. A lever 144 whose one end is fixed to the ball-striking rod 143 and a pin capable of engaging with the ball-striking cam is formed at the other end; It consists of a spring 145 that is tension-biased and whose tension is varied to change the strength of the ball hit by changing the rotation angle of a ball hitting handle (not shown) provided on the front surface of the game board. Then, the ball hitting cam 1 is rotated by the rotational force of the motor 141.
42 rotates, the arc-shaped part of the ball-striking cam 142 and the pin of the lever 144 come into contact with each other, causing the ball-striking rod 143 to rotate intermittently, thereby driving the pachinko balls with electric power. It is something to hit the ball with. Although the illustration shows an electric ball hitting mechanism, a ball hitting lever connected to the ball hitting rod 143 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.

Further, on the back side of the game board, a path 118 is provided that guides the out balls guided to the back side through the out ball inlet 3 and the winning balls guided through the path 117 downward. Balls and winning balls (ie, hit balls) are returned to a prize ball tank (not shown) provided at the top of the pachinko game machine by an appropriate return means. This path 118 is generally provided with a ball sensor 15 for detecting balls in order to know the operating state of the pachinko game machine.
is provided in a related manner. As another example, an out ball sensor may be provided in the out ball passage 119 to detect out balls.

FIG. 2 is an illustrative view showing an example of a variable winning ball device and its opening/closing drive mechanism applied to the present invention and arranged in a pachinko game machine. In the figure, variable winning ball device (Yakumono; commonly known as chulip) 2
has a beak-like part (commonly known as a tulip petal) 211 to catch the pachinko balls falling along the board.
It is fixed to the plate 212 and placed on the board of the pachinko game machine. A lever 213 is provided in relation to this beak-shaped portion 211 for guiding winning balls to the back surface of the game board. This lever 213 is formed with a protruding pin 214 so that it can be opened electrically by an opening mechanism 20, which will be described later.

In the opening mechanism 20, one end of an L-shaped lever 24 is fixed to the tip of a solenoid shaft 23 that is attracted by the urging of a solenoid 22, and the other end of the L-shaped lever 24 is engaged with a pin 214. A plate-like piece 25 is formed for this purpose. This plate-like piece 25 has a through hole through which a pin 214 can be inserted, and by inserting the pin 214 into the through hole, the L-shaped lever 24 can be moved in the sliding direction (arrow direction). The pin 214 and the plate-shaped piece 25 are engaged with each other.
This L-shaped lever 24 is supported at its vertical center by a screw 26 so as to be slidable in the vertical direction.
Due to the suction of the solenoid 22, the solenoid shaft 23
is slid downward in conjunction with being sucked downward, pushing down the pin 214 to open the beak-shaped part 211, and by deenergizing the solenoid 22, the solenoid shaft 23 is pushed upward to open the plate-shaped part. The piece 25 is pulled upward, the lever 213 is returned to its original position, and the beak-shaped portion 211 is closed.

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. Devices 2a to 2e and opening mechanism 2
They are shown in correspondence with 0a to 20e. In addition, in the illustration, an opening mechanism is provided corresponding to each of the variable winning ball devices 2a to 2e, and a case is shown in which the opening mechanism is individually opened with the corresponding opening mechanism, but as another example, one opening mechanism is provided. A plurality of groups of yakumono predetermined in advance may be commonly developed. For example, Yakumono 2a~
A first opening mechanism that commonly opens the Yakumono 2c and a second opening mechanism that commonly opens the Yakumono 2d and 2e are provided, and by driving the first opening mechanism or the second opening mechanism, multiple opening mechanisms are provided. You may also control the opening of Yakumono by group.

In addition, although the case of the variable winning ball device was described as a chulip, other variable winning ball devices may be used as long as they can change the state in which pachinko balls are easily won and the state in which it is difficult to win.

FIG. 3 is an illustrative view of another example of the variable winning ball device, in which pachinko balls are made easier to win by opening the plate forward. Referring to the drawings, the configuration of the variable winning ball device 30 in the other rows will be described. A plate 32 that can be opened toward the front of the game board is rotatably supported on the frame member 31. A pachinko ball receiving part 33 in which pachinko balls can be won is formed in the upper part of this frame member 31. plate 32
A lever 34 is fixed to the lever 34.
By pulling upward, the plate 32 is opened forward. This lever 34 has a lever 35
One end of the lever 35 is engaged, and the other end of the lever 35 is pivoted around a fulcrum 36. A part of one end side of this lever 35 is connected to the solenoid 3 via the lever 37.
8 plunger 39.

When the solenoid 38 is energized, the plunger 39 is attracted and the lever 35 is rotated upward via the lever 37.
The lever 34 engaged with one end of the game board 5 is pulled up to push the plate 32 forward of the game board and open it. In addition, the opening time of the variable winning ball device 30 can be controlled by the energization time of the solenoid 38. Furthermore, by energizing the solenoid 38 intermittently, the number of openings of the variable winning ball device 30 can be controlled by the number of times the solenoid 38 is energized.

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 toward the top. The rotating position of the disc is determined so as to receive the falling pachinko balls, 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. .

FIG. 4 is a basic block diagram of one embodiment of the present invention. An outline of the invention will be explained along with the configuration of this basic block. The initial ball output rate setting unit (first ball output rate setting means) 41 determines the ball output rate (for example, a relatively high ball output rate) in the initial reset state.
This is to set the target ball output rate setting section (second
The ball payout rate setting means 42 is for setting a target ball payout rate in the initial reset release state (for example, a relatively low ball payout rate after a certain time after the player starts playing the game). A ball output rate setting output set in advance by both setting sections 41 and 42 is given to a variable pulse generation circuit 43. This variable pulse generation circuit 43 is capable of generating output pulses by varying the frequency (or period) of the output pulse in multiple stages in which the ball output rate can be variably set. The frequency of the output pulse is set to a relatively low frequency so that a relatively high ball payout rate is set by the initial ball payout rate setting section 41 in response to the initial reset signal given from the signal deriving means) 44. The driving circuit 46
give to This drive circuit 46 counts the output pulses of the variable pulse generation circuit 43 when the output of a condition detection section such as the special prize ball detection switch 12 is received or at a certain repetition period, and generates a predetermined pulse from the start of counting. During the time until counting, the solenoids 22a to 22e are energized continuously or intermittently to open each Yakumono 2a to 2e, so that the pachinko balls hit on the game board are in a state where it is easy to win a prize. let As a result, when the player is playing the pachinko game machine in the initial reset state, the player can win a prize with a relatively high probability, and can therefore win a large amount of prize balls.

Then, the target ball output rate switching signal generating section 45 is activated after a predetermined time has elapsed since the initial reset signal generating section 44 derived the initial reset signal, or when it is manually operated by an attendant at the gaming hall. ,
A signal for instructing switching to the target ball output rate is generated and applied to the variable pulse generation circuit 43. Accordingly, the variable pulse generating circuit 43 increases the frequency of the oscillation output pulse (that is, shortens the period) so that the ball output rate set by the target ball output rate setting unit 42 is achieved. is applied to the drive circuit 46. Thereafter, when the condition detection unit 12 or a certain repetition period signal is applied, the drive circuit 46 counts the output pulses of the variable pulse generation circuit, and only counts the output pulses from the start of counting until the predetermined number of pulses are counted. The solenoids 22a to 22e are energized and controlled continuously or intermittently to make it easier for pachinko balls to land in the respective jackpots 2a to 2e.

In this way, by changing the frequency of the output pulses of the variable pulse generation circuit 43 in stages, the time it takes for the drive circuit 46 to count a predetermined number of pulses becomes shorter than the frequency based on the initial ball output rate setting section 41. In a state where the target output pulse is long and an output pulse based on the target ball output rate setting unit 42 is applied, the solenoid is energized and controlled by a signal that is relatively short until the count up. As a result, in the initial reset state, the winning probability for each Yakumono is high, and after switching to the target ball payout rate, the opening time of each Yakumono is shortened, so the ball payout rate is controlled to be lowered. Therefore, for players,
In the initial reset state, a relatively large amount of prize balls can be obtained easily, but after the target ball payout rate is switched, the payout rate becomes relatively low, and in effect, the player can borrow a relatively small amount. You can play for a long time depending on the number of balls.

The initial ball output rate setting section 41 and the target ball output rate setting section 42 constitute a ball output rate setting means that can appropriately set the ball output rate to a first value and a second value. Further, the target ball output rate switching signal generating section 45 constitutes switching condition detection means for detecting that a predetermined condition for switching the ball output rate of the pachinko gaming machine is satisfied. Furthermore, the switching is performed from the first gaming state in which the variable winning ball device is controlled by the variable pulse generating circuit 43 and the driving circuit 46 so that the ball payout rate of the pachinko gaming machine approaches the first value. winning state switching drive for switching the game control state to a second gaming state in which the variable winning ball device is controlled so that the ball payout rate of the pachinko game machine approaches the second value based on the detection output of the condition detecting means; A control means is configured.

Next, a more specific circuit will be explained in detail.

FIG. 5 is a specific circuit diagram of an embodiment of the present invention. In this embodiment, variable pulse generation circuit 4
3, by using an astable multivibrator (hereinafter referred to as astable multi), the frequency of the output pulse can be varied by switching the time constant circuit section that can vary the repetition period of the output pulse of the astable multivibrator. It is composed of

Next, with reference to FIGS. 1 to 3 and 5, the specific configuration and operation of FIG. 5 will be explained. Generally known astable multipliers connect the bases of transistors T1 and T2 via capacitors C2 and C1 to the collectors of the other transistors T2 and T1 in a cascade manner. Power supply (+V)
A resistor is connected between the base of each transistor and the power supply, and the frequency (or duty) of the output pulse is determined by the time constant of the collector resistor and the capacitor.

By the way, in the non-stable multiplayer used in this embodiment, the resistors R11 to R15 connected between the collector of one transistor T1 and the power supply (+V) have different resistance values, and the initial ball output rate setting section 41 has different resistance values. An example of an initial ball rate setting switch 41
Parallel circuits 1 to 415 and target ball release rate setting switches 421 to 425, which are an example of the target ball release rate setting unit 42
are connected in series to the transistors 431 and 432, and the emitters of the transistors 431 and 432 are commonly connected to the collector of the transistor T1,
Switches 411 and 421, switches 412 and 42
2. Switches 413 and 423, switches 414 and 424, and switches 415 and 425 are connected in common to each resistor R11, R12, R13, and R1.
4, configured by connecting to R15. Then, any one of switches 411 to 415 and switch 4
By closing any one of resistors 21 to 425, any two of resistors R11 to R15 are selected, and the switching operation of transistor 431 or 432 corresponds to the initially set ball output rate. This is to switch to a resistance corresponding to the resistance or the target ball payout rate. For example, when the resistor R11 is selected, the time constant becomes the largest, the frequency of the output pulse of the unstable multiplier becomes lower, and the time for opening and driving the Yakumono is lengthened, thereby increasing the ball output rate. Similarly, resistors R12, R
13, R14, and R15, the time constant is gradually decreased to increase the oscillation frequency of the unstable multiple and lower the ball output rate. Therefore, for example, when resistor R11 is selected, the ball payout rate is set to be the highest 120%, and resistor R12
When is selected, the ball output rate is relatively high 110%
Let the ball output rate when resistor R13 is selected be a medium 100%, the ball output rate when resistor R14 is selected be a relatively low 90%, and the ball output rate when resistor R15 is selected. Assuming that the ball rate is the lowest, 80%, the switch 412 is pressed and closed in advance to make the ball output rate relatively high (for example, 110%) in the initial state, and the target ball output rate is compared. switch 42 to achieve a low percentage (for example, 90%).
Press 4 to close it.

When a player first arrives at a pachinko machine or when the game parlor opens, a gaming parlor staff member turns on the initial reset switch 4, which is installed at a location away from the pachinko machine, such as at a prize exchange place.
Press 41. This initial reset switch 44
1, a high level (hereinafter referred to as "H") signal is sent to the flip-flop (hereinafter referred to as "FF") 4 included in the variable pulse generation circuit 43 via the initial reset switch 441 and OR gate 442.
30 and gives an operation command signal to the timer 451. Since the transistor 431 becomes conductive in response to the reset of the FF 430, a series circuit of the resistor R12, the switch 412, and the transistor 431 is formed between the collector of the transistor T1 and the power supply line. By this,
The astable multi-channel generates a frequency that depends on the resistance value of the resistor R12, and the AND included in the drive circuit 46
It is given as one input of gate 461. this
AND gate 461 is the special prize ball detection switch 1
2 detects the special prize ball, the output is FF46
2, so during the period when the set output of the FF 462 is being given, the output pulse of the unstable multi is given to the counter 463 for counting. This counter 463 makes its output a low level (hereinafter "L") signal until it counts a predetermined count value, and derives an "H" signal when it counts up. Therefore, the counter 463 becomes "L".
During the period when the signal is being derived, the "L" signal is inverted to the "H" signal and provided as one input of the AND gate 464. Therefore, when the FF 462 is set, the AND gate 464 supplies power from the power supply circuit 465 to the solenoids 22a to 22e to open the solenoids 2a to 2e. When the counter 463 counts up, the count-up output is delayed by the delay circuit 467 to reset the FF 462, reset the count value of the counter 463, and stop supplying power to the solenoid.

As another example of generating the initial reset signal, for example, an initial clear signal generation circuit 443 that generates an initial clear signal at the same time as the power is turned on when a game parlor opens is provided, and the initial clear signal of the output thereof is You can reset the FF430 with a traffic signal, or at a predetermined time while the store is open (for example, every 3 hours from the time the store opens until 5 p.m.)
A timer circuit 444 may be provided to generate an initial setting signal, and the initial reset may be performed using the output of the timer circuit.

After an initial reset so that the ball payout rate is relatively high, after a certain period of time determined by a timer 451 has elapsed, the timer 451 derives a time-up output and sets the FF 430 via an OR gate 453. As a result, the transistor 431
becomes non-conductive and the transistor 432 becomes conductive, so that the power supply (+V) and the transistor T1
A resistor R14 and a switch 42 are connected between the collector of
A series circuit of 4 and transistor 432 is formed. Accordingly, the astable multi generates a relatively high frequency pulse with a time constant based on resistor R14;
Thereby, the ball output rate is controlled to be relatively low.

In this way, when a player starts playing pachinko, if the initial reset is performed using the manual switch, the ball payout rate is set to be a relatively high ball payout rate, and after a certain period of time, the ball payout rate is set to the normal payout rate. Since the ball rate can be changed, players can win a relatively large amount of prize balls for a certain period of time from the start of the game, and can use those prize balls to play for a long time. The advantage of renting inexpensive pachinko balls is that you can play for a long time and increase your interest.

By the way, people who are skilled in gaming techniques and are known as pachinko players come to pachinko gaming parlors as players, and these players often win a large number of pachinko balls by themselves, so the above-mentioned It is not preferable to perform initial reset using the output of the timer circuit 444 at certain fixed time intervals. Therefore,
A target ball output rate switching command switch (for example, a residual contact type switch) 452 is provided so that when an attendant at the game hall sees a Pachi-Pro machine, he or she presses the target ball output rate switching command switch 452 corresponding to that machine. The circuit is configured so that the output of 452 is given as an inhibit input to AND gate 445. This prohibits the initial reset operation even though there is an output from the timer circuit 444. At the same time, the output of the switch 452 is applied as a reset input to the flip-flop 430 via the OR gate 453, thereby resetting the FF 430 and forcibly switching to the target ball output rate.

Further, if the player becomes aware that the ball payout rate has changed, the player may change machines and play the game on another machine set at a higher ball payout rate. Therefore, the time-up time of the timer 451 can be variably adjusted to a desired time, and if a player changes machines, the staff can press the target ball output rate switch 452 to change the time from the start of the game. What is necessary is to have the player play the game at the target ball payout rate.

In addition, in the above-mentioned embodiment, a case was explained in which a hardware circuit was used to control the winning state switching drive, but it could also be achieved by software processing using an arithmetic processing device such as a microprocessor. You can also. Therefore, as another embodiment of the present invention, a case will be described in which the payout rate is variably set by software processing.

A numerical display 68 for displaying numerical information is provided.

A switching condition detection means is configured to detect that a predetermined condition for switching and changing the ball payout rate of the pachinko gaming machine is satisfied.

FIG. 8 is a flowchart for explaining the operation when switching and setting the ball output rate, which is a feature of the present invention. Next, with reference to FIGS. 6 to 8, a specific operation for automatically switching the ball payout rate will be described.

First, the initial or target ball payout rate settings, and the automatic reset time and automatic switching time settings will be described. Increased ball payout rate to 110% in initial reset state
Let us now consider the case where the target ball output rate is set to 90%. First, the setting key 662 is pressed and then the manual reset key 641 is pressed to preset the ball output rate (110%) in the initial reset state.
In addition, if there are multiple pachinko machines, press setting key 6.
It is sufficient to specify the machine number before performing the operation in step 62. Accordingly, the CPU 71 determines that any key is pressed in response to the fact that the setting key 662 is pressed first, and selects the setting key 662 (i.e., 641, 642, not the automatic reset key or the manual reset key). , 651, 652), and proceeds to other processing.However, it is determined that the setting key 662 and manual reset key 641 are pressed, so that it is determined that the initial ball payout rate is being set. A ball output rate of 110% in the initial reset state is set and stored in the initial ball output rate storage register 746. Further, when setting the target ball output rate to 90%, press the setting key 664 and then press the target ball output rate manual switching key 651. Depending on the CPU71
The ball output rate is 90% in the target ball output rate storage register 747.
to remember. In addition, if the initial reset is to be performed automatically every certain period, in order to set the automatic reset time, operate the numeric keys 61 to input the time (for example, 3 hours), and then press the time key 63.
Press. As a result, the CPU 71 stores the automatic reset time in the register 748. Furthermore, if you want to automatically switch from the initial reset state to the target ball output rate, operate the numeric key 61 to set the automatic switching time (for example, 30 minutes, or 0.5 minutes).
After inputting the time) and pressing the time key 63,
The CPU 71 stores the automatic switching time in the register 749.

Next, an explanation will be given of the operation when switching the ball payout rate based on the ball payout rate and time set as described above. First, a case will be described in which initial reset and target ball output rate switching are performed manually. An attendant at the game parlor confirms that a player has arrived at the pachinko game machine and started playing the game (if there are multiple pachinko machines, after specifying the machine number), he presses the manual reset key 641. In response, the CPU 71 determines that any key has been pressed, determines that it is not an automatic reset switch, determines that it is a manual reset key, and then reads out the initial ball payout rate stored in the register 746. , the switch 4 of the variable pulse generating circuit 43' is activated based on the ball output rate (110%).
12 is closed. As a result, the variable pulse generating circuit 43' generates a relatively low frequency pulse determined by the resistance value of the resistor R12, and supplies it to the drive circuit 46. The drive circuit 46 activates and controls the solenoids 22a to 22e to obtain an initial ball output rate (110%) each time there is an output from the special prize ball detection switch 12 or at a certain repetition period so that the probability is relatively high. control so that

At this time, the CPU 71 determines that the target ball output rate automatic switching switch 652 is not pressed and the target ball output rate manual switching key 651 is not pressed, and if there is an output from the winning ball detection switch 134, the register Add 1 to the number of winning balls stored in the register 750 to cumulatively count and store the number of winning balls, and every time there is an output from the ball hitting sensor 15, the number of balls hit so far stored in the register 751 is counted and stored. The number of balls hit is cumulatively counted by adding the numerical value 1 to the number of balls. Then, calculate the number of prize balls by multiplying the number of winning balls by the number of balls paid out per winning ball, divide the number of prize balls by the number of balls struck to find the ball output rate, and calculate the ball output rate. After storing this in the register 752, it is again determined whether the target ball output rate automatic switching or manual switching switch 652 or 651 is pressed, and the process waits until either one is pressed. Then, after a certain period of time, when the staff member presses the manual changeover switch 651 to switch the ball output rate from the initial reset state to the target ball output rate, the CPU 71 changes the register 747 in response to the manual changeover key 651 being pressed. A switch 412 is opened and a switch 414 is closed in order to read out the target ball output rate stored in the target ball output rate (90%) and change the output frequency of the variable pulse generating circuit 43' based on the target ball output rate (90%). As a result, the variable pulse generating circuit 43' switches the output frequency to a relatively high frequency, and the drive circuit 46 controls the opening time of the Yakumono so that the ball release rate is relatively low (90%). do. Then, the setting operation for the ball output rate is completed, and it is determined whether any of the keys mentioned above has been pressed. If not, the operation for calculating the number of winning balls, the number of balls hit, and the ball output rate is repeated. .

Next, a case will be described in which the initial reset state is automatically set and the ball output rate is automatically switched to the target ball payout rate. If the initial reset is to be performed automatically, an attendant at the game parlor presses the automatic reset switch 642 and the target ball output rate automatic changeover switch 652 in advance. The automatic reset switch 642 and the automatic transfer switch 652 are preferably illuminated residual contact switches, and are provided with an indication of the automatic reset and automatic switching states. Therefore, the CPU 71 determines that any key is pressed, determines that the automatic reset switch is pressed,
It is determined whether the automatic reset time stored in register 748 is reached. If the automatic reset time has not been reached, the number of winning balls, the number of balls hit, and the ball output rate are calculated, and the same operation is repeated. Then, when the time of the timer 73 reaches (or passes) the automatic reset time set in the register 748,
The CPU 71 reads out the initial ball output rate stored in the register 746, closes the switch 412 corresponding to the ball output rate, and controls the variable pulse generation circuit 4.
3' output pulse is switched. By this,
The drive circuit 46 controls the opening of the Yakumono based on the frequency of the output pulse of the variable pulse generating circuit 43' so that the ball release rate is relatively high.

Further, the CPU 71 determines that the target ball output rate automatic changeover switch 652 is pressed and determines whether the automatic changeover time (for example, 30 minutes) has elapsed. If not, the operation of calculating the number of winning balls, the number of balls hit, and the ball output rate is repeated. Then, when the automatic switching time has elapsed, the CPU 71 closes the corresponding switch 414 and opens the switch 412 based on the target ball payout rate (90%) stored in the register 747. As a result, the ball payout rate is subsequently switched to a relatively low one.

Incidentally, in the above description, a case has been described in which both the initial state and the target ball output rate setting command are performed manually or automatically, but manual and automatic may be combined in the initial state or target setting state.

In addition, as mentioned above, the variable pulse generation circuit 43'
The ball payout rate can be changed by changing the oscillation frequency, but in reality, the factors that change the ball payout rate are the nail adjustment for each pachinko machine and the player's We cannot ignore the fact that it depends on the quality of gaming technology. Therefore, more preferably, the ball payout rate may be switched based on the difference between the actual ball payout rate and the target ball payout rate. For example, after switching the switch and therefore the output pulse of the variable pulse generating circuit 43' so as to achieve the above-mentioned target ball output rate, the CPU 71 determines whether a certain period of time (for example, one hour) has elapsed; Wait until it has passed. Then, after a predetermined period of time has elapsed after switching the opening state of the Yakumono so as to achieve the target ball output rate, the CPU 71 registers the register 752.
Register 7 from the actual ball rate stored in
The target ball output rate stored in 47 is subtracted, and it is determined whether the difference in the ball output rate is within a certain range (for example, ±5%). If it is within a predetermined range, it will stop without switching the switch,
If it exceeds a certain range (±5%), determine whether it exceeds the positive value, and if it exceeds the positive value, switch to the switch one level lower (for example, 415), and if it exceeds the positive value (i.e., negative value). If so, by switching to the switch 413 one step higher, switching control is performed so as to bring the ball output rate closer to the target ball output rate.

As described above, in this embodiment as well, it is possible to switch the ball payout rate into two stages by software processing.

The drive circuit 46 and the variable pulse generation circuit 43'
By CPU71, ROM72 and RAM74,
A first control in which the variable winning ball device is controlled so that the ball payout rate of the pachinko game machine approaches the first value.
from the gaming state to a gaming control state in which the variable winning ball device is controlled so that the ball payout rate of the pachinko gaming machine approaches the second value based on the detection output of the switching condition detection means; A winning state switching drive control means is configured to switch the winning state. There have been various means for changing the ball payout rate of a pachinko machine, as described in Japanese Patent Application Laid-Open No. 141736/1983, such as a variable winning ball device. There are various methods such as changing the probability of a predetermined condition that changes to a state where it is easy to win a prize, or changing the probability that a condition that repeats and continues to be satisfied in a type of pachinko game machine where a variable winning ball device repeatedly remains in a state where it is easy to win a prize. The following are possible. The point is that the winning state of the variable winning ball device can be changed by any method using the winning state switching drive control means.

In the two embodiments described above, the ball output rate is set relatively high in the initial reset state, and the ball output rate is made relatively low after a certain period of time automatically or manually. This switching control has the advantage that the player can play the pachinko game for a long time with the number of borrowed balls for a relatively small amount of money, making the pachinko game even more enjoyable. By the way, as mentioned above, if the ball output rate is fixedly controlled to be high in the initial state and then lowered after a certain period of time, the players will become aware of such a state and it will become more interesting. This can lead to problems that are extremely undesirable to game hall operators. Therefore, contrary to the above explanation, by keeping the ball output rate relatively low in the initial reset state, it can be used as a play table, and even after the time when it has been operating as a play table, it can be used patiently for a long time. It is also possible to control the player who is playing the game to increase the ball payout rate so that the player can stop playing the game quickly. In that case, there is an advantage that can be achieved extremely easily by simply changing the setting of the ball payout rate.

In addition, in the above explanation, the method of calculating the ball output rate to be set is based on the ratio of the number of prize balls and the number of balls hit, but the ratio between the number of supply balls and the number of out balls is calculated. , the ratio between the number of prize balls and the number of out balls, or the ratio between the number of supply balls and the number of balls struck. Furthermore, it is not limited to the ball output rate, but also information related to the ball output rate such as the winning rate (number of winning balls ÷ number of balls struck) (i.e. the winning rate and the number of balls paid out per winning ball). It should be pointed out that the technical idea of the present invention can be applied even in the case of variably setting the ball payout rate (multiplying the ball payout rate).

[Effects of the Invention] As described above, according to the present invention, the ball payout rate of the pachinko gaming machine, which is initially controlled to approach the first value set in the gaming parlor, changes to the second value halfway. The switching is controlled and fluctuates so that it approaches
By setting the first value and the second value to desired values at the gaming parlor, it is possible to change the ball output rate from a certain desired ball output rate to another desired ball output rate during business hours, and the We have now been able to provide a ball payout rate control device for pachinko gaming machines that can meet the needs of the players.
