Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a pinball game machine in which a game is played by hitting a ball, such as a pachinko game machine or a coin game. This relates to a pinball game in which a prize is paid out when a ball hits a predetermined area. It is widely popular and is loved by players as one of the easy cash registers.As is well known, Pajinko Crying Game has multiple safe holes and winning ball devices (Yakumono) arranged on the board. In addition, many nails are driven into the board surface near the safe hole and the entrance of the Yakumono, so that when a player hits a purchased pachinko ball onto the board, the pachinko ball will fall due to the action of the nails. The winning ball will be changed and fall, and the winning ball will land in the safe hole or the Yakumono with a probability of winning.From now on, each time a winning ball is placed in the safe hole or the Yakumono, a certain number of prize balls will be paid out, but the winning ball and the hit ball will be paid out. The winning rate of the prize balls, which is correlated to the ratio of winnings (i.e. winning rate), is determined by the spacing and angle of the many lights formed on the board. Yes, the number of visitors and sales of the amusement center are determined by the quality of the ball output rate, but if the ball output rate is too high, it will be a loss-making business for the eight players, which is not desirable. In order to desirably avoid the entrance of a large number of players, in the past, a needle craftsman adjusted the nails formed on the game board based on the sunrise ball rate for each pachinko, so that each pachinko could have a higher payout. However, the conventional method of adjusting the ball output rate by adjusting the lights on each pachinko hole 10 required the skill of the needle maker, and There is a problem that there is a gap between the expected ball output rate and the actual ball output rate, and that it takes a lot of effort to adjust dozens or hundreds of pachinko machines or all of the pachinko machines in the game hall. Therefore, even if you are not a skilled needleworker, you can easily increase the ball payout rate (
There was a demand for a pachinko game that could adjust the winnings or winnings ($) and the payout rate extremely quickly.In addition, coin-operated gaming machines had multiple safe holes and yakumono arranged on the board. If you insert a metal (or coin), you can play a game of hitting pachinko balls for a predetermined number of times or for a predetermined time, and each time the hit pachinko ball hits a safe hole or a prize, a predetermined score is accumulated, and one game is completed. Each time the score in one game period exceeds the median score that can pay out metal for supplies, f121 metals are paid out.Even in such coin games, the number of coins that can be earned in one game is is determined by the winning rate in the safe hole and the Yakumono, but the winning rate was adjusted by the spacing or angle of the nails formed around the safe hole and the Yakumono.Therefore, even in coin game entertainment, It is desired that the winning rate can be easily adjusted even by a non-skilled person such as a needle maker, and that the winning rate and opening pattern can be adjusted extremely quickly. It is an object of the present invention to provide a new pinball game in which the winning rate can be easily adjusted and the winning rate can be adjusted extremely quickly. Such a pinball game machine is arranged on the game board of the pinball game machine, and the pachinko balls hit into the game board can be changed into a state in which it is easy to win a prize and a state in which it is difficult to win a prize. An eccentric prize ball device, a winning rate variable setting means for variably setting a winning rate of pachinko balls that win in the variable winning ball device by changing the state of the variable winning ball device, and electrically driving the variable winning ball device. and a drive control means that variably controls the state of the variable winning ball device based on the output of the variable winning rate setting means, and the variable winning rate setting means is a manual drive control unit that variably sets the winning rate by manual operation. 5 Effect 1 By manually operating the winning rate variable setting means consisting of the manual setting means, the winning rate of pachinko balls that win into the variable winning ball device is variably set, and the variable winning rate 92 The variable winning ball device is electrically driven and variably controlled in accordance with the predetermined setting state.As a result, the winning rate variable setting means is manually operated by an attendant of the gaming hall v) PI3 to variably set the winning rate. By doing so, the drive control of the variable winning ball device is performed according to the winning rate. [Embodiment of explanation] Next, an embodiment of the present invention will be described in detail based on the drawings. (hereinafter referred to as #, white) -,・1. Figure 1 is an external view of a pachinko game machine according to an embodiment of the present invention. In the configuration, on the game board 1 of the pachinko game machine 10 of this embodiment, there are a pachinko ball passing area (for example, a path through which pachinko balls can pass) 2a + 2b + 2c, and a plurality of (five in the illustration) variable winning ball devices. (hereinafter referred to as yakumono) 3a to 3e, and an out-ball entry 0 shed for collecting pachinko balls that do not win in any of the yakumono 3a to 3e are provided. Note that, if necessary, a window 5 is formed in the approximate center of the game board 1, and a variable display member (for example, a segment display that displays numbers) that can variably display multiple types of identification information is provided in the window 5. 6a+6b+6c may be provided. This variable display member 5a+(3b+6C) is, for example, a passage area 2a+2
Corresponding to b+2c, the display state is variably displayed every time the hit pachinko ball passes through the corresponding passing area. Then, when the combination of display states of the plurality of variable display members (for example, a combination of numbers) reaches a predetermined state, the winning rate (or ball payout rate) is set in advance based on that state. To start the electrical opening/closing operation of the variable winning ball device, or to perform the opening operation for a certain period of time or a certain number of times after regularly or irregularly driving the variable winning ball device to open/close electrically. used. By the way, the winning rate is determined by the ratio of winning balls to the number of batted balls, and the winning rate is determined by the number of prize balls to the number of batted balls. Since the number of balls paid out for each winning ball is fixed, this winning rate is calculated by multiplying the counted number of winning balls by the number of balls, and calculates the ratio of the number of prize balls and the number of batted balls. It can be calculated as follows, and as a result, there is a correlation that results in the winning rate. Further, at the lower part of the front panel of the pachinko game machine, there is a prize ball payout port 11 that pays out a prize ball when a Yakumono 3a to 3e pachinko ball wins, and a prize ball payout port 11 that pays out a prize ball and a player who pays out a prize ball from the prize ball payout port 11. A ball waiting gutter 12 that guides a plurality of pachinko balls purchased from a ball rental machine to a hitting position for hitting one after the other, and a hitting handle 13 that adjusts the strength of hitting by rotating the pachinko ball. and a batting ball switch 131 for instructing the player to hit the pachinko ball guided to the batting position by the batting ball waiting gutter.
A prize ball receiving tray 14 and a prize ball payout 111 are provided. In addition, variable display members 6a to 6 with one condition that can be driven to open (or open/close) the Yakumono as needed.
A guide display board 15 may be provided to indicate the combination of identification information of C or to explain the game method. 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 winning pachinko balls to the Yakumono 3a to 3e downward, and the paths 211 to 215 are formed to guide the pachinko balls downward through the respective paths. A path 216 is formed that guides pachinko balls to the winning ball processing device 23. Furthermore, passing ball detection switches 22a+22b and 22c are provided on the back surface portions corresponding to the passing areas 2a+2b and 2c. This passing ball detection switch 22a+22b+
Based on the passing ball detection output of 22c, the variable display member 6
This allows the identification information displayed at a+5b+6c to be varied. The prize ball processing device 23 rotatably supports a cylindrical member 231 provided at a position to receive pachinko balls guided through a path 216 by a support member 232, and a socket 233 is formed at the tip of the cylindrical member 231. However, a winning ball detection switch 234 is provided at a lower position in the rotating direction of the cylindrical member 231, and the cylindrical member 231 is returned to its original position! Contains vt235. Then, when the pachinko ball is guided to the socket 233 via the path 216, the pachinko ball rides on the socket 233 and moves to the cylinder member 233 due to the weight of the ball.
When rotating downward, the winning ball detection switch 234 is pressed and activated by the rotation of the cylindrical member 2310. When the 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. Thereafter, the pachinko ball riding on the socket 233 is guided to the path 218 via the path 217, and the return mechanism 235 is activated to return the cylindrical member 231. In this way, one winning ball is detected one after another. In addition, on the back of the pachinko machine, Yakumono 33-3e
Opening/closing mechanisms 30a to 30e for electrically driving the opening/closing
(described in detail in FIG. 3A below) is provided. Further, an electric ball hitting mechanism 24 is provided below the back surface of the game board. This electric ball hitting mechanism 24 is connected to the ball hitting switch 13.
A motor 241 is rotationally driven by the pressure of the motor 241, and a batting rod 243 is rotationally driven by the rotational force of the motor 241.

It consists of 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 with each other, causing the ball-striking rod 243 to rotate intermittently. Pachinko balls are hit by electric power. Although the illustration shows the case of an electric ball hitting mechanism, the ball hitting rod 24
It goes without saying that a manual ball hitting mechanism may also be used, in which a ball hitting lever connected to 3 is provided on the front surface, and the player manually hits one pachinko ball one by one by flicking the ball hitting lever with his or her finger. do not have. Further, on the back side of the game board, a path 218 is provided to guide downwardly the out balls guided to the back side via the out ball input and the winning balls guided via the path 217. Out balls and winning balls (i.e. batted 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 218 is generally provided with a hit ball sensor 25 in order to detect a hit ball for the purpose of knowing the operating state of the pachinko game machine. Further, as another example, an out ball sensor may be provided in the out ball passage 219 to detect an out 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 tulip) 3 has a beak-shaped portion (commonly known as tulip petals) 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 313KH1
In order to enable electrical opening with the opening mechanism 30 described below,
A pin 314 is formed to protrude. In the opening mechanism 30, one end of an L-shaped lever 34 is fixed to the tip of a solenoid shaft 33 that is attracted by the urging of a solenoid 32, and a pin 3 is fixed to the other end of the L-shaped lever 34.
A plate-like piece 35 is formed which engages with 14. This plate-like piece 35 has a through hole through which a pin 314 can be inserted, and by inserting the pin 314 into the through hole,
The pin 314 and the plate-shaped piece 35 are engaged with each other in the sliding direction (arrow direction) of the L-shaped lever 341. This L-shaped lever 34 has a screw 36 at the center in the vertical direction.
The solenoid 3 is slidably supported in the vertical direction.
As the solenoid shaft 83 is sucked downward by the suction of 2, the solenoid shaft 83 is slid downward, pushing down the pin 314 and opening the beak 31-1, and the solenoid 32 is deenergized, so that the solenoid shaft 33 upward to pull up the plate-shaped piece 35, return the lever 313, and remove the beak-shaped part 311.
It is the one that closes the. In addition, although the illustration explains the relationship between one set of variable winning ball device and the opening machine/groove, in the state shown in Fig. 2 and in the following explanation, 2- and -e are added to the end of each part. The variable winning ball devices 3a to 3e and opening mechanisms 30a to 30e are shown in correspondence with each other.
A case will be described in which an opening mechanism is provided corresponding to each of 3e, and Yakumono is opened individually with the corresponding opening mechanism, but as another example, multiple groups of Yakumono predetermined in one opening mechanism can be opened in common. It may also be something that is developed separately. For example, a first opening mechanism that commonly opens the Yakumono 3a to 3c and a second opening mechanism that commonly opens the Yakumono 3d and 3e are provided, and the first opening mechanism or the second opening mechanism is provided. By driving, opening and opening of the Yakumono may be controlled by dividing into a plurality of groups. Although the case of the tulip has been described as the variable winning ball device, other variable winning ball devices may be used as long as the pachinko ball can be changed between a state in which it is easy to win and a state in which it is difficult to win. FIG. 3B is an illustrative view of an example of a pond of a variable winning ball device, in which the plate is opened forward to make it easier for pachinko balls to win. The structure of another fFl variable winning ball device 370 will be explained with reference to the drawings.
1, a plate 372 that can be opened toward the front of the game board is rotatably supported. At the top of this frame member 371,
A pachinko ball receiving section 373 is formed in which pachinko balls can be won. A lever 374 is fixed to the plate 372, and by pulling the lever 374 upward, the plate 3
72 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 part of one end side of this lever 375 is connected to the solenoid 378 via the lever 377.
plunger 379. When the solenoid 378 is energized, the plunger 379 is sucked and the lever 375 is moved through the lever 377.
By rotating the lever upward, the lever 374 engaged with one end of the lever 375 is pulled up, and the plate 37
2 to the front of the game board to open it. In addition, the variable winning ball device 3 depending on the energization time of the solenoid 378
70 opening times can be controlled. Also, solenoid 378
By intermittently energizing the solenoid 37,
The number of openings of the variable winning ball device 370 can be controlled by the number of times of energization of 8. Further, 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 a state in which it is easy to win a pachinko ball is provided. If you want to make it difficult for people to catch falling pachinko balls, set the safe hole entrance to the upper side and position the disc so that it can catch the falling pachinko balls. The disk may be rotated so as to face in the horizontal direction. FIG. 4A is a circuit diagram of an opening/closing drive control means according to an embodiment of the present invention, 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 cycle of opening and closing of the Yakumono, a winning rate variable setting means ÷ 2, and driving the opening and closing of the Yakumono 3a to 3e.

e, and the solenoids 32a to 32e. The frequency dividers 43a to 43e have different frequency division ratios, and for example, the pachinko balls 3a and 3c provided on both sides of the pachinko game machine can easily win a prize, and the pachinko ball 3b in the center can easily win a prize. However, if the probability of winning the two Yakumono 3d and 3e in the lower row is about halfway between them, the frequency division ratio of the frequency divider 43b should be set to a relatively large value (for example).
), and the frequency divider 43a. Select the frequency division ratio of 43c to a relatively small value (for example, yo),
The frequency division ratios of the frequency dividers 43d and 43e are selected to be a medium value (for example, j). FIG. 5 is a waveform diagram for explaining the operation of FIGS. 4A and 4B, and in particular, for example, (a) shows the output pulse p l of the ri variable pulse generation circuit q41, and (b) shows the frequency division. (c) 'r!,
(d) shows the output pulse p2 of the H-pulse oscillation circuit 47, and (e) shows the output pulse S of the ND gate 4I6a. Next, the first
The specific circuit configuration and operation of FIGS. 4A and 4B will be described with reference to FIGS. 4A to 5. The variable pulse generating circuit 41 outputs an output based on the winning rate setting of the winning rate variable setting means 42 in order to vary the cycle of opening/closing driving of the beak of the Yakumono. 'j: Generates pulses with variable high-level and low-level tonnage ratios (that is, duty).This variable pulse generation circuit flaw 1 is an example of an unstable multivibrator (hereinafter referred to as an unstable multivibrator) as shown in Figure 4B. ) is used.A commonly known non-stable multiplier is such that the base terminals of transistors Tl and T2 are cascade-coupled via a capacitor C2°CI and connected to the collectors of the other transistors T2 and Tl. , T2 collector and power supply (+E')
The frequency (or duty) 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, in the astable multiplier used in this embodiment, one transistor T
Resistor R1 connected between the collector of 1 and the power supply (+E)
1, R12, and R13 can be switched by contacts 421, 422, and 423, which are an example of the winning rate variable setting means 42,
And make the resistance values of the resistors R11, R12, and R13 different (for example, the resistance value of R11 is set to 100°, the resistance value of R12 is set to 100°,
By setting Rl3 to a small value), the frequency (or duty) of the output pulse can be changed by making it possible to switch the time constant determined by the resistance value of one of the selected resistors R11, R12, R13 and the capacitance of the capacitor C1. It is made to be variable. This winning rate variable setting means 2
For example, each contact point 421, 422, 4123 can be a manual switch, placed on the back of the game board, and manually set appropriately before opening, or each manual switch can be placed in a monitoring room with staff. You can then manually select and set the settings as appropriate in the monitoring room. Then, when the manual switch 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 cycle of opening and closing the Yakumono becomes slower. Set to have the lowest winning rate. In addition, by closing the manual switch 422, the resistor R12 with a medium resistance value is
By selecting , the winning rate is set to be medium. In addition, when the manual switch 423 is closed and the resistor R13 with the smallest resistance value is selected, the time constant becomes smaller and the frequency of the output pulse becomes higher, and the cycle of opening and closing the Yakumono becomes faster, so the winning rate increases. Set it 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 three stages, but if you want to widen the variable setting range, the number of stages should be configured to be switchable to multiple stages. Bye. By the way, the ball output rate, which is calculated by the ratio of the number of batted balls and the number of prize balls (number of prize balls ÷ number of batted balls), is calculated as follows: the number of prize balls is the number of winning balls plus 1
Since it is calculated by multiplying the number of pitches paid out according to the number of pitches received by fX, it is correlated with the winning rate (number of winning pitches divided by number of pitches hit). As mentioned above, contacts 4+21.422.
If the winning rate is variably set by switching 423, the winning rate can be variably set based on the above correlation. Note that each contact point of the variable setting means 42 is 21°422.
423 may be a relay contact, and the switching may be performed remotely and automatically based on the gaming state, as will be explained later in FIG. 9. Furthermore, as another example of the winning rate variable setting means 42, the resistors R11 to R'13 and the contact 421-4
23, the collector of the transistor T1 and the power supply (+
A variable resistor may be inserted between E) so that the frequency of the output pulse can be varied over a wide range. Trees can be considered. For example, the oscillation 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 contact point 42 included in the entry prize rate variable setting means 42
The operation will be described assuming that the resistor R12 is closed and the resistor R12 is selected. The variable pulse generating circuit 41 generates a pulse pl with a medium constant period (T1), and outputs the pulse pl to the frequency divider 43.
Give as input of a=436. For example, frequency divider 43
If the frequency divider 43a divides the output pulse p1 by 1, the frequency divider 43a divides the output pulse p1 as shown in FIG. 5(b).
10. A high level (hereinafter referred to as "rHJ") signal and a low level (hereinafter referred to as "rLJ") signal are alternately derived for each individual signal and supplied to the differentiating circuit 44a. The differentiating circuit 44a differentiates the rising frequency of the frequency-divided pulse q, and gives an operation command to the monostable multi-pulse 45a as a signal. Accordingly, the monostable multi 45a derives the output r of the rHJ signal for a predetermined period of time and outputs the AN
D game) 46a is given as one input. By the way, in the normal state, the pulse oscillation circuit 47 has a cycle (T2) such that it generates one pulse every time (for example, 0.5 to 1 second) required to open and close the beak of the yakumono once. A pulse p2 is generated at , and is applied as the other input of AND gates 46a to 46e. Therefore, AND game 141a
During the period when the output pulse r of the ld monostable multi 45a is applied, the output pulse p2 of the pulse oscillation circuit 47 is derived, and the output pulse S is applied to the transistor 48a, and the transistor 48a is intermittently activated by the number of output pulses S. Make conductive. This causes the solenoid 32a to
The gate 46a is intermittently energized by the number of output pulses (this time in the figure), thereby repeatedly driving the beak 311 of the yakumono 3a to open and close by the number of output pulses S. Similarly, each of the other frequency dividers 43b-43e divides the output pulse p1 of the variable pulse generation port +1'841 by a predetermined frequency division ratio, and each divided pulse is divided by the corresponding differentiating circuit 44b- Differentiate the rise at 44e to obtain monostable multi 4
5b-45e, and while each monostable multi 45b-45e derives the rHJ signal for a certain period of time, each AND gate 46b-46e outputs the output pulse p of the pulse oscillation circuit 47.
2, the corresponding transistors 48b-48e are intermittently made conductive (that is, repeatedly turned on and off), thereby intermittently energizing each solenoid 32b-32e, and the beak of each of the yakumono 3b-3e is intermittently energized. Open and close the shaped part repeatedly. Note that, as described above, each frequency divider 43a=
Since the frequency division ratio of 436 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 in which each Yakumono 3a to 3e is driven to open and close becomes different. Next, a case will be described in which the payout rate (winning rate) is varied by switching settings of the input winning rate variable setting means 42. For example, even though the contact point 422 is closed as described above and a medium 2-ball rate is set, the game is stopped due to poor nail adjustment or poor player skill. If the pachinko machine is to be opened to other players after it is under control, the staff member must open the manual switch (contact) 422 provided on the back of the game board and close the manual switch 421, or Contacts 422 are opened and contacts 421 are closed by remote control from the monitoring room. Additionally, when a player is playing pachinko and wants to reduce the ball payout rate remotely from the monitoring room because the pachinko machine has a good ball payout rate, 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 increases the time constant determined by the resistor R11 and the capacitor CI, and thus lowers the frequency of the output pulse p1. By lowering the frequency of the output pulse pl of the variable pulse generation circuit 4+1, the frequency divider 43a
The period of the output frequency-divided pulse is delayed, and therefore the appearance phase (period) of the rI(J signal of the monostable multi 45a is delayed. At this time, the output frequency of the pulse oscillation circuit 47 and the period of the rHJ signal of the monostable multi 45a ( 1) is constant, the number of opening and closing cycles of the Yakumono 3a is a constant number (4 times in the waveform diagram of FIG. 5), but the r of the monostable multi 45a
Since the appearance phase of the HJ signal is delayed, the total opening time of the Yakumono 3a becomes shorter than when the contact 422 is closed. Therefore, the probability that a 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, if you want to change the settings to increase the winning rate, open the contact 422 manually or remotely and open the contact 422.
By closing 3, the frequency of the output pulse of the variable pulse generation circuit 41 becomes high, and the monostable multi 45a-
The rHJ signal appearance period of the 45e output is accelerated, and Yakumono 3
The total opening time of a to 3e 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 the ball output rate is controlled to be increased. 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 while the gaming hall 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 or not there are winning conditions for other safe holes, etc., and the service for players can be improved. There are advantages. In addition, since each Yakumono is repeatedly opened and closed for a certain unit time, it is easy to attract the attention of the players and has the advantage that 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 balls are individually and intermittently driven to open and close at irregular intervals, but only one winning ball device at a predetermined position is repeatedly opened and closed. It may also be driven. As a modification of FIG. 4A, when the Yakumono 3a and 3b are grouped and repeatedly driven to open and close, the frequency divider 43
b. Without providing the differentiating circuit 44b and the monostable multi 45b, the circuit may be connected so as to give the output of the monostable multi 45a to the other input of the A N D gate 6b. When grouping Yakumono 3d and 3e at the same depth and driving them repeatedly to open and close, the monostable multi 45d
The circuit may be connected so that the output of the AND gate 46e is provided as the other input of the AND gate 46e. In addition, as another modification, if it is desired to vary the number of times each Yakumono is repeatedly opened and closed, the rHJ signal derivation periods (i.e., time constants) of the monostable multis 45a to 45e may be selected to be different. Furthermore, as another modification, if it is desired to equalize the period of repeatedly opening and closing the beak-shaped part of the yakumono and the period of rest of the repetitive opening and closing operation, the output of each frequency divider 43a-43e is connected to the corresponding AND gate 46a''- The circuit may be configured such that it is directly supplied as the other input of the frequency divider 43ax43e.In addition, an N-ary counter that generates a pulse every time a different predetermined number is counted may be used instead of the frequency divider 43ax43e. Furthermore, if the pachinko game machine is equipped with an electric ball striking mechanism, each machine will be repeatedly opened and closed for a unit time only when a player is playing the game, and the repeated opening and closing operation will be stopped when no player is present. If you want to
In order to derive the outputs of the ND gates 46a to 46e, the suppression output of the ball hitting switch is calculated by dividing each AND gate ÷ 6a so that the hitting switch 131 is pressed as a condition.
~46e may be commonly given. In this way, when no player is present, the solenoids 32a to 32
Since it is possible to prevent energizing e, it is possible to prevent burnout of the solenoid, which has the advantage of extending the life of the solenoid. Furthermore, if you want to open and close a plurality of yakumono irregularly and repeatedly based on the gaming state that occurs during a pachinko game, you can do as follows. For example, the plurality of variable display members 6a. If the combination of identification information displayed on 6b and 6c becomes a predetermined combination, the Yakumono can be repeatedly opened and closed, and the variable display member 6a. The circuit may be configured to detect the display states of 6b and 6c to determine whether or not a predetermined combination is achieved, and to activate the AND gates 46aP-46e when the predetermined combination is achieved. FIG. 6 is a circuit diagram showing an opening/closing drive control means according to another embodiment of the present invention. In addition, the above-mentioned FIG. 4A. The same parts as in FIG. 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 generation circuit 61 generates a pulse p3 having a short "H" signal period, a long rLJ signal period, and a variable period (T3), as shown in FIG. 7 (axis), for example. The rHJ signal period is selected to be the time required to energize the solenoid to open the yakumono. Specifically, the variable pulse generation port 61 uses a circuit as shown in FIG. The capacitance of C1, the resistance value of resistor R3, and the capacitance of capacitor C2 are determined, and the resistance values of resistors R11, R12, and R13 are determined so that the cycle T3 (i.e., frequency) can be varied in order to vary the winning rate. be done. The output pulse p3 of the variable pulse generating circuit 61 is given as one input of AND gates 48a to 46e, and is also given as the input of AND gate 631, and is further given as one input of AND gates 632 and 633. . On the other hand, the pulse oscillation circuit 62
generates a pulse p4 (pulse with period T41; see FIG. 7(b)) with a constant frequency higher than that of the pulse p3, and AN
Provided as one input to D gate 631. This AND
The other input of the gate 631 is provided with an inverted output from an OR gate 63, which will be described later, as an inhibit input. AND
The gate 631 is configured so that the pulse p3 is the rLJ signal and the OR
During the rLJ signal period, the output of the gate 634 converts the output pulse p4 of the pulse oscillation circuit 62 into the output pulse p5 (seventh
(see figure (c)), and the pulse p5 is applied to the ring counter 641. This ring counter 6 increments the count value every time there is a pallet 295 manpower, and cyclically counts the number corresponding to the number of the variable winning ball devices 3a to 3e, and the count value is 1 to 5. has an output end corresponding to
The rHJ 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. In a state where the ring counter 64 is counting the numerical value l accordingly, the output pulse p3 of the variable pulse generation circuit 61
When becomes the rHJ signal, 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 counting state of the number 1, and the pulse m of the rHJ signal is output from the output terminal corresponding to the number 1.
1 is derived and AND game is performed via the OR gate 65a) 4
6 Give to a. At this time, since the AND gate 46a is given the pulse p3, the AND gate 46a
derives an output pulse s1, causing transistor 48a to conduct. This energizes the solenoid 32a,
During the signalable period of the pulse p3, the variable winning ball device 3a is opened. Then, when the pulse p3 is reversed to the rLJ signal, the solenoid 32a is deenergized, so the variable winning ball device 3a is closed. By this, 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 the rLJ signal, the AND gate 631 derives the pulse p4 output from the pulse oscillation circuit 62 as the output pulse p5, and supplies it to the ring counter 64. Therefore, the ring collar 64 is the output pulse p4 of the pulse oscillation circuit 62.
The count value is sequentially incremented by 1 in synchronization with the count value, and output pulses m2, m3,
m 4 + m 5 is derived, but at this time pulse p3
Since is the "L" signal, none of the solenoids is energized, and therefore none of the variable winning ball devices 3a to 3e are opened. Note that, below the waveform of the output pulse p5 of the AND gate 631 shown in FIG. 7, the counted value of the ring counter 64 when the pulse p5 is sequentially applied is shown for ease of understanding. As described above, the AND gate 631 outputs the output pulse p
5, the ring counter 64 cyclically increments its count value, but when the output pulse p3 of the variable pulse generation circuit 361 is inverted to the rHJ signal, the output of the AND gate 631 is is prohibited, and the count value counted by the ring counter 64 immediately before that (for example, 5
) is applied to the AND gate 46e via the OR gate 65e. For this reason, AN
D-gate 46e derives an output pulse s5 to conduct transistor 4I8e and fully energize solenoid a 2 e. Thereby, the pulse p 3 (D r HJ
During the signal period, the variable winning ball device 3e is opened,
When the signal is inverted to rLJ, the variable winning ball device 3e is closed. Therefore, as a result, the variable winning ball device 3e is opened/closed and driven only once. Similarly, when the pulse p3 is at the timing of the rHJ 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. Since it can be easily understood by referring to it, its explanation will be omitted. In this way, in the embodiment shown in FIG. 6, the signal is irregularly determined at a timing determined by a combination of the cyclic count value of the ring counter 6 and the rHJ signal appearance period of the output pulse p3 of the variable pulse generation circuit 61. Variable winning ball devices 3a to 3e
Either of these is controlled/controlled. By the way, in this embodiment as well, the resistors R11°R12, R1
3 to change the period T3 (or frequency) of the output pulse p3 of the variable pulse generation circuit 61, the appearance phase (period) of the rHJ signal of the output pulse p5 can be made slower or faster. I can do it. For this reason, variable winning ball devices 3a to 3
The total opening time of e can be shortened or lengthened,
This allows the winning rate (ball payout rate) to be variably set. Note that the pachinko playing state (for example, the variable display member 6a)
If you want to group a plurality of variable winning ball devices based on the combination state of the identification information displayed in , 6b, 6c) and drive them to open and close intermittently repeatedly, you can do as follows. That is, the passage area 2a shown in FIG.
Each time a pachinko ball passes through 2b, 2c, the identification information of the corresponding variable display members 6a, 6b+6c is controlled to be displayed variably, and the combination of identification information of each variable display member 6a, 6b, 6c is detected by the game state detection means 66. Configure to detect with. This game state detection means 66 is a predetermined variable display member 6a that can open three variable winning ball devices 3a to 3c.
, 6b, 6c is detected, “
Derive the "H" signal and use flip-flop (FF) 6?
Set it to 1. This set output is AND gate 63
2 as the other input of OR gate 6.
It is applied as an inhibit input to an AND gate 631 through 3 points. Therefore, when the gaming state detecting means 66 detects the gaming state, the counting operation of the ring counter 641 is stopped. Then, each time the pulse p3 becomes the rHJ signal, the AND gate 632 derives the pulse p3 and ORs it.
Gates 65a, 65b. A corresponding AND gate 46a via 65c. It is given as the other input of 46b and 46c. Accordingly, AN
The D gates 46a, 46b, 46c are connected to the corresponding transistor 4 during the rHJ signal period of P/L, 7°p3.
8a, 48b, and 48c are made conductive, and the solenoid 323,
32b, 32c, thereby opening and closing the three variable winning ball devices 3a, 3b, 3(3).At this time, the output pulse of the AND gate 632 is applied to the OR gate 6.
35 to an N-ary counter 68. For this reason, the N-ary counter 8 is counted a predetermined number of times (for example, 5
Three variable winning ball devices 3a are grouped by the number of times). When 3b and 3c are driven to open and close simultaneously, a count-up output is derived and the FF 671 is reset. As a result, when the game state reaches a predetermined condition, the plurality of grouped variable prize winning ball devices are driven to open and close. In addition, the game state detection means 66 has two variable winning ball devices 3.
．． If a condition that allows opening and closing of d and 3e is detected, FF6
72, derives the pulse p3 via the AND gate 633, and supplies it as one input to the OR gates 65d and 65e, thereby generating the two variable winning ball devices 3d.
, 3e are opened and closed. In addition, in the above explanation, the variable pulse generator circuit shell or 6

The output frequency of 61 may be variably controlled. Therefore, a case will be described below in which the output frequency of the variable pulse generation circuit is automatically varied.

Contains keys corresponding to the number of stages in the range that can be variably set (or winning rate). For example, assuming that the range in which the payout rate can be variably set is five levels, five setting keys 871 to 875 are provided. The setting key 871 sets the ball output rate to the lowest rate (for example, 80%), the setting key 872 sets the ball output rate to a low rate (for example, 90%), and the setting key 873 sets the ball output rate to a medium rate. Set the rate (for example, 100%) and press the setting key 87.

If necessary, the operation panel 80 may include a thumb rotary switch 88 for setting the number of stops for all pachinko machines installed in the game parlor, and numerical information entered manually using the numerical keys 81. A numeric display 89 for displaying . FIG. 9 is a block diagram showing an arithmetic processing unit 90 and its related parts included in the winning rate variable setting means according to a preferred embodiment of the present invention. This preferred embodiment provides that the contact 42
1 to 425, the operation panel 80, and the arithmetic processing unit 90 constitute a winning rate variable setting means that automatically and variably sets the winning rate (that is, the ball output rate). Next, a case in which the output frequency of the variable pulse generation circuit is automatically variable controlled will be described with reference to FIGS. 4B, 8, and 9. For example, as mentioned above, the setting keys 871, 872° 87

%, 110%, 120%, press setting key 87
After pressing 1 and inputting 80t manually by operating the numerical key 81, pressing the ball output rate setting key 84, pressing the setting key 872 and inputting 90 by operating the numerical key 81, the ball output rate Press setting key 8 and input the ball output rate for each setting key 873, 874, and 875 in the same manner. The ball payout rate corresponding to each setting key set in this way is stored in the processing data storage memory (for example, the storage area corresponding to each setting key of RA 94. In addition, when setting with winning rate is 1 for each winning ball.
If 5 pachinko balls are to be paid out, set key 87
Press numbers 1 to 875 and operate the numeric keys 81 to get a winning rate of 5.3%, 6 (G), 6.6 (G), and 73 (T). 8 (go) and then press the winning rate setting key 85. That is, the value obtained by dividing the ball output rate by the number of balls paid out per one winning ball becomes the winning rate corresponding to the ball output rate. 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. Thereafter, the setting keys 871 to 875 corresponding to the desired ball output rate are pressed. For example, the number 1 pachinko machine's ball payout rate is 100%.
If you want to set the ball output rate of the 2-fold pachinko machine to 110% and the number 3 ball output rate to 90%, press the machine number key 831, enter 1 with the numerical key 81, and then press the setting key 87.
3, press machine number key 831, and press numeric key 8.
After inputting 2 with 1, the setting key 874 is pressed, the machine number key 831 is pressed, and after inputting 3 with the numerical 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 payout rate for each machine number is set in this way, the arithmetic control unit 91 uses the RAM 94
The ball output rate corresponding to the operated setting key is written and stored as a standard ball output rate in the storage area for each machine number. 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 284 for each pachinko machine
The output of the box and ball sensor 25 is constantly input to the calculation section 92. The calculation unit 92 selects each pachinko machine in time sequence at a relatively high speed, and if there is an output from the hit ball sensor 25 of the selected pachinko machine, it cumulatively counts the hit balls and turns on the winning ball detection switch 234I. If there is an output, the number of balls paid out is added to one winning ball and cumulatively added to the number of prize balls up to that point (i.e., the number of balls paid out for each winning ball is added to the number of winning balls as a result) Calculate the number of prize balls by multiplying the numbers) and find the ratio between the number of prize balls and the number of balls hit (that is, the ball output rate). Then, the calculation unit 92 repeats the operation of calculating the actual ball output rate for each pachinko machine, and stores the ball output rate in the memory for storing the ball output rate.
RAM) 93 is stored by machine number of the pachinko machine. The variable pulse generating circuit 41 (included in the pachinko machine of each machine number) is
'! or 61). For example, the No. 1 pachinko machine closes the contact 423 included in the variable pulse generation circuit 41 to set a medium payout rate (100%), and the No. 2 pachinko machine closes the contact 423 and sets it to a medium payout rate (100%). The number 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 output yaw of each pachinko machine stored in the RAM 93 in order of each machine number. It compares the standard ball output rate stored in the RAM'94 and determines which contact to switch to among the contacts 421 to 425 based on the magnitude relationship between the actual ball output rate and the reference ball output rate. Specifically, the arithmetic control unit 91 determines whether, for example, the actual ball payout rate of the No. 1 pachinko machine is the standard ball payout rate (
It is determined whether the ball is above or below a range (for example, ±5%) of If the ball is closed and the ball is lower, the ball payout rate will be one level higher (1
10%), and contact 424 is opened so that
close. This makes it possible to control the actual ball payout rate so that it approaches the standard ball payout rate. Thereafter, in the same way, the arithmetic control unit 91 compares the standard ball payout rate and the actual ball payout rate for each machine number, and compares the ball payout rate with the actual ball payout rate so that the ball payout rate is close to the standard ball payout rate ((one step higher or lower ball payout rate). By the way, in pachinko game parlors, in order to know the operating status of each pachinko machine, information such as the number of balls hit, the number of prize balls, and the difference between them is displayed at all times. The management device of the game hall is installed so that the machine number is automatically displayed when the staff at the game machine or the staff designates the machine number. Look at the number information,
For a player who has won a large number of prize balls, there may be cases where it is desired to manually change the playing rate before the time set by the timer 912 for resetting the room attendance rate is reached. In such a case, the staff member operates the numerical keys 81 included in the operation panel 80 to enter the machine number of the pachinko machine and presses the machine number designation key 831 to specify the machine, thereby changing the number of pachinko machines. Press any of the desired setting keys 871 to 875 for which you want to change. Accordingly, the arithmetic control unit 91 via the interface 96 sets the contact point 42 corresponding to the designated ° setting key included in the winning rate variable setting means of the pachinko machine.
By closing any one of the terminals 1 to 425 and opening the previously closed contacts, the winning rate can be automatically and remotely set. In this embodiment, the ball payout rate (or winning rate) can be quickly set before the opening of the game hall by a simple operation even if you are not an expert such as a nailsmith, and the ball payout rate (or winning rate) can be set in advance during the opening of the game hall. Based on the standard ball payout rate and the ball payout rate during actual operation, the contact points can be automatically switched and the actual ball payout rate can be controlled to approach the standard ball payout rate, and moreover, it can be controlled remotely. It has the advantage of being able to be switched manually. The operation panel 80 and the arithmetic processing device 90 may be provided in conjunction with or integrally with a gaming hall management device that manages the operating status of each pachinko machine in the gaming parlor and controls termination based on the operating status. You can. In addition, in the above-mentioned embodiment, the case where the payout rate of a pachinko machine is variably controlled was explained as an example of a pinball game machine, but it can also be applied to a coin game machine. For example, if the technical idea of the present invention is applied to a coin gaming machine that awards points according to winning balls to a winning ball device and pays out prizes (coins) based on the number of points, the winning rate of the winning ball device can be improved. By varying the number of points obtained, the points that can be obtained can be set remotely, thereby making it possible to vary the payout rate of the original item. In other words, the ball output rate can be easily set variably by manual operation, and the variable winning ball device is controlled according to the set ball output rate, so even non-skilled nailers can easily adjust the ball output rate. To provide a pinball game that can be adjusted in a very short time without the need to adjust the nails formed on the game board surface to adjust the ball output rate.

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a pinball game machine, such as a pachinko game machine or a coin game machine, in which the game is played by hitting balls. This invention relates to a pinball game machine in which a prize ball is paid out when a hit ball enters a predetermined area. [Prior Art] In general, pinball gaming machines such as pachinko gaming machines and coin gaming machines in which games are played by hitting pachinko balls have become widespread and are popular among players as a convenient form of leisure. As is well known, pachinko machines have multiple safe holes and winning ball devices (yakumono) arranged on the board, and many nails are driven into the board surface near the entrances of the safe holes and the yakumono. When a player drives a purchased pachinko ball along the board, the falling direction of the pachinko ball is changed by the action of the nail and the ball falls, and there is a probability that the ball will land in a safe hole or a yakumono. At this time, a certain number of prize balls are paid out each time a prize is won in the safe hole or the Yakumono, but the prize ball payout rate that correlates to the ratio of the winning ball to the hit ball (i.e. winning rate) is It is determined by the spacing and angle of the numerous nails formed on the surface. Pachinko parlors with a good ball payout rate are popular with players, and the quality of the ball payout rate determines the number of visitors and sales of the parlor, but if the ball payout rate is too high, the pachinko parlor will be unable to manage This is not desirable for the company as it will lead to deficit management. Therefore,
In order to attract a large number of players and be desirable for the management of the game hall, conventionally, a nailer adjusts the nails formed on the game board surface of each pachinko machine based on the previous day's ball payout rate. The ball payout rate of each pachinko machine was adjusted. 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 the expected ball payout rate due to the nailer's nail adjustment is different from the actual ball payout rate. There have been problems in that there are discrepancies in the payout rate of pachinko machines, and that it takes a great deal of effort to adjust all the pachinko machines in a game hall. Therefore, there has been a need for a pachinko game machine that can easily adjust the ball payout rate (or winning rate) even if the player is not an expert like a nailsmith, and can adjust the ball payout rate extremely quickly. In addition, coin-operated gaming machines have multiple safe holes and holes on the board, and when you insert a metal (or coin), you can play pachinko balls for a predetermined number or for a predetermined time, and the pachinko balls you hit are safe. A predetermined score is accumulated every time a prize is won in a hole or a prize, and each time the score in one game period exceeds the unit score that can be used to pay out prize metal, the number of metanodos is determined. Even in such coin-operated gaming machines, the number of coins that can be earned in one game is determined by the winning rate in the safe hole and the Yakumono, but the winning rate can be adjusted by adjusting the spacing between the nails formed around the safe hole and the Yakumono. Or it was done by angle. [Problems to be Solved by the Invention] Therefore, it is desired that coin gaming machines be able to easily adjust the winning rate even if they are not experts such as nail makers, and that the winning rate can be adjusted extremely quickly. In view of the above circumstances, the present invention aims to provide a new pinball game machine that allows even non-experts to easily adjust the winning rate and to adjust the winning rate extremely quickly. do. [Means for Solving the Problems] The pinball game machine according to the present invention is arranged on the game board of the pinball game machine and has two states in which pachinko balls that are hit into the game board are easy to win and difficult to win.

The device is electrically driven and variably controlled. As a result, the winning rate variable setting means is manually operated by an attendant of the game hall to variably set the winning rate, and the variable winning ball device is driven and controlled in accordance with the winning rate. [Embodiments of the Invention] Next, embodiments of the present invention will be described in detail based on the drawings. FIG. 1 is an external view of a pachinko game machine according to an embodiment of the present invention. In the configuration, on the gaming board 1 forming the gaming area of the pachinko gaming machine 10 of this embodiment, there are passage areas 2a, 2b, 2c for pachinko balls (for example, paths through which pachinko balls can pass), and a plurality of ( Variable winning ball devices (hereinafter referred to as Yakumono) 3a to 3e (five in the figure) and an out ball population 4 that collects pachinko balls that do not win in any of the Yakumono 38 to 3e are provided. Note that, if necessary, a window 5 is formed in the approximate center of the game board 1, and a variable display member (for example, a segment display that displays numbers) that can variably display multiple types of identification information is provided in the window 5. 6a, 6b, and 6c may be provided. These variable display members 6a, 6b. 6C corresponds to passage areas 2a, 2b, 2c, for example,
Each time a hit pachinko ball passes through a corresponding passing area, its display state is variably displayed. The plurality of variable display members 6 a * 6 b * 6 c and the window 5 include a plurality of variable display parts corresponding to the plurality of passing areas, and a display that is configured according to the manner in which the batted ball passes through the plurality of passing areas. A variable display device is configured as an example of variable display means that changes the state. Then, when the combination of display states (for example, a combination of numbers) of the plurality of variable display members reaches a predetermined state, the winning rate (or ball payout rate) is set in advance based on that state. start the electrical opening/closing operation of the variable winning ball device to give gaming value, or
Alternatively, after regularly or irregularly driving the variable winning ball device to open and close electrically, the opening operation is performed for a certain period of time or a certain number of times, and is used to award game value. This variable display means constitutes a gaming device that operates according to the falling path of the ball hit into the gaming area and brings a predetermined gaming value into a state that is profitable to the player. ing. By the way, the winning rate is determined by the number of winning balls compared to the balls hit, and the winning rate is determined by the number of prize balls compared to the balls hit. Since the number of balls paid out for each winning ball is fixed, this ball output rate is calculated by multiplying the counted number of winning balls by the number of balls, and calculates the ratio between the number of prize balls and the number of balls batted in. It can be calculated as follows, and as a result, there is a correlation that results in the winning rate. Further, at the lower part of the front panel of the pachinko game machine, there is a prize ball payout port 11 that pays out a prize ball when a Yakumono 38 to 3e Hepachinko ball wins a prize, and a prize ball payout port 11 that pays out a prize ball and a player who pays out a prize ball from the prize ball payout port 11. A batting ball waiting gutter 12 that guides a plurality of pachinko balls purchased from a ball rental machine to a batting position so that they can be hit one by one, and a batting ball handle 13 that adjusts the strength of the batting ball by rotating the gutter. and a batting ball switch 131 for instructing the player to hit the pachinko ball guided to the batting position by the batting ball waiting gutter.

In addition, the variable display members 6a to 6c have defined conditions for driving the Yakumono to open (or open and close) as needed.
A guide display board 15 may be provided to describe combinations of identification information or to explain gaming methods. 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 winning pachinko balls to the Yakumono 3a to 3e downward, and the paths 211 to 215 are formed to guide the pachinko balls downward through the respective paths. A path 216 is formed that guides pachinko balls to the winning ball processing device 23. Further, on the back surface corresponding to the passing areas 2a, 2b, 2c, passing ball detection switches 22a, 22b,
22c is provided. This passing ball detection switch 22a,
The identification information displayed on the variable display members 6 a * 6 b * 6 c is changed based on the passing ball detection outputs 22 b and 22 c. The prize ball processing device 23 rotatably supports a cylindrical member 231 provided at a position to receive pachinko balls guided through a path 216 by a support member 232, and a socket 233 is formed at the tip of the cylindrical member 231. However, a winning ball detection switch 234 is provided at a lower position in the rotational direction of the cylindrical member 231, and a return mechanism 235 for returning the cylindrical member 231 is included. 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 causes 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 to a prize ball payout mechanism (not shown) as a signal to instruct a payout of a certain number of prize balls, and a predetermined number of prize balls, which are an example of game media, are paid out and a game value is given. . 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 pachinko ball sitting on the socket 233 moves to the path 21.
7 to the path 218, and the return mechanism 235 operates to return the cylindrical member 231. In this way, one winning ball is detected one after another. In addition, on the back of the pachinko machine, Yakumono 38~3e
Opening/closing mechanisms 30a to 30e for electrically driving the opening/closing
(described in detail in Figure 3A below) is provided. Further, an electric ball hitting mechanism 24 is provided below the back surface of the game board. This electric ball hitting mechanism 24 is connected to the ball hitting switch 131.
a motor 241 that is rotationally driven by the pressure of the motor 241; 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 has a pin formed at the other end that can be engaged with a ball hitting cam, and a lever 244 for tensioning and biasing the ball hitting rod 243 and varying the tension depending on the rotation angle of the ball hitting handle 13 to change the strength of the ball hit. spring 245
It consists of. 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 with each other, causing the ball-striking rod 243 to rotate intermittently. Pachinko balls are hit by electric power. In addition, although the illustration shows the case of an electric ball hitting mechanism,
It goes without saying that a manual ball-striking mechanism may be used, in which a ball-striking lever connected to the ball-striking rod 243 is provided on the front, and the player manually hits pachinko balls one by one by flicking the ball-striking lever with his or her finger. . Furthermore, a path 218 is provided on the back side of the game board to guide downwardly the out balls guided to the back side via the out ball population 4 and the winning balls guided via the path 217. Out balls and winning balls (i.e. batted 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 218 is generally provided with a hit ball sensor 25 in order to detect a hit ball for the purpose of knowing the operating state of the pachinko game machine. Further, as another example, an out ball sensor may be provided in the out ball passage 219 to detect an out 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 tulip) 3 has a beak-shaped portion (commonly known as tulip petals) 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 313 has
In order to enable electrical opening with the opening mechanism 30 described below,
A pin 314 is formed to protrude. In the opening/closing mechanism 30, one end of an L-shaped lever 34 is fixed to the tip of a solenoid shaft 33 that is attracted by the energization of a solenoid 32, and a pin 31 is attached to the other end of the L-shaped lever 34.
A plate-like piece 35 is formed for engaging with 4. This plate-like piece 35 has an insertion hole through which a pin 314 can be inserted, and by inserting the insertion hole 314, the plate-like piece 35 can be pinned in the sliding direction (arrow direction) of the L-shaped lever 34. 314 and the plate-like piece 35 are engaged with each other. This L-shaped lever 34 has a screw 36 at the center in the vertical direction.
The solenoid 3 is supported so that it can slide vertically.
As the solenoid shaft 33 is sucked downward by the suction of 2, the solenoid shaft 33 is slid downward, pushing up the pin 314 and opening the beak 311, and the solenoid 32 is deenergized, so that the solenoid shaft 33 is moved downward. The plate-shaped piece 35 is pushed upward, and the lever 313 is returned to close the beak-shaped part 311. 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. 38
3e and opening mechanisms 30a to 30e. In addition, in the illustration, an opening mechanism is provided corresponding to each of the variable winning ball devices 3a to 3e, 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. It may be possible to commonly develop a plurality of groups of yakumono determined in advance. For example, a first opening mechanism that commonly opens the Yakumono 3a to 3C and a second opening mechanism that commonly opens the Yakumono 3d and 3e are provided, and the first opening mechanism or the second opening mechanism is provided.
The opening of the Yakumono may be controlled for each group by driving the opening mechanism. Although the case of the tulip has been described as the variable winning ball device, other variable winning ball devices may be used as long as the pachinko ball can be changed between a state in which it is easy to win and a state in which it is difficult to win. 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 3
72 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 part of one end side of this lever 375 is connected to the solenoid 378 via the lever 377.
plunger 379. When the solenoid 378 is energized, the plunger 379 is sucked and the lever 375 is moved through the lever 377.
By rotating the lever upward, the lever 374 engaged with one end of the lever 375 is pulled up, and the plate 372
The game board is opened by pushing it out to the front of the game board. In addition,
Variable winning ball device 37 depending on the energization time of the solenoid 378
0 opening time can be controlled. Also, by intermittently energizing the solenoid 378, the solenoid 378
The number of openings of the variable winning ball device 370 can be controlled by the number of times of energization. Further, as yet another example of a variable winning ball device, a rotatable disk with one or more safe holes formed on the board is arranged on a game board, so that it is easy to win a pachinko ball. If you want to make it difficult to win, set the rotational position of the disc so that the entrance of the safe hole faces upwards to receive the falling pachinko ball, and if you want to make it difficult to win, set the entrance of the safe hole to face downwards or sideways. The disc may be rotated so that it faces the target. In short, in both the variable winning ball device shown in FIGS. 3A and 3B and the disc-shaped variable winning ball device, a predetermined number of prize balls are paid out when a pachinko ball wins, and one winning ball pays out a predetermined number of prize balls. It includes a passage area set such that a fixed number of prize balls are paid out in response to the passage of the ball. 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 a Yakumono 3.
Frequency divider 4 is used as a control circuit for opening/closing driving of 8 to 3e.
3a to 43e, differentiating circuits 44a to 44e, monostable multi 45a to 45e, AND gates 46a to 46el pulse oscillation circuit 47. It consists of transistors 48a to 48e and the solenoids 32a to 32e. This frequency divider 43a
-43e have different frequency division ratios, for example, the Yakumono 3s provided on both sides of the pachinko machine.
a, 3c Hepachinko balls make it easier to win and the middle Yakumono 3b is the place to win.
, 3e, the probability of winning a prize is somewhere in the middle, then the frequency divider 4
The frequency division ratio of frequency dividers 3b is selected to be a relatively large value (for example, 1/20), the frequency division ratio of frequency dividers 43a and 43c is selected to be a relatively small value (for example, 1/10), and the frequency division ratio of frequency dividers 43d and 43e is selected to be a relatively small value (for example, 1/10). Select a moderate value (for example, 1/16) as the frequency division ratio. 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 p1 of the frequency divider 43.
(C) shows the output pulse q of a, and (C) shows the output pulse q of monostable multi 45a.
(d) shows the output pulse p2 of the pulse oscillation circuit 47, and (e) shows the output pulse S of the AND gate 46a. Next, with reference to FIGS. 1 to 5, the specific circuit configuration and operation of FIGS. 4A and 4B will be explained. 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. (i.e. duty ratio)
It generates pulses with variable values. As this variable pulse generating circuit 41, for example, an unstable multivibrator (hereinafter referred to as an unstable multivibrator) as shown in FIG. 4B is used. A generally known non-stable multiplexer connects the base terminals of transistors TI and T2 to capacitors C2 and CI.
cascade-coupled through the other transistor T2.
It is connected to the collector of TI, and a resistor is connected between the collector of each transistor TI, T2 and the power supply (+E).
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 connects the collector of one transistor T1 and the power supply (+E).
The resistors R11, R12°R13 connected between the contact points 421, 422, 423 of the winning rate variable setting means 42
and resistors R11, R12, R1
By making the resistance values of 3 different (for example, making the resistance value of R11 large, R12 medium, and R13 small), the resistance value of one of the selected resistors R11, R12, and R13 and the capacitance of capacitor C1 can be adjusted. By making it possible to switch the time constant determined by
is made variable. 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 employee is present, and the manual switch is placed on the back of the game board. You can select and set the settings as appropriate. Then, 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 therefore the period of driving the opening and closing of the Yakumono becomes slower. The rate is set to be the lowest. In addition, the contact 422 is closed and the resistor R1 with a medium resistance value is
By selecting 2, the winning rate is set to be medium. In addition, when the contact 423 is closed and the resistor R13 with the smallest resistance value is selected, the time constant becomes smaller, the frequency of the output pulse becomes higher, and the period of driving the opening and closing of the Yakumono becomes faster, so the winning rate increases. is set so that it is 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 ball payout rate, which is calculated by the ratio of the number of batted balls to the number of prize balls (number of prize balls/number of batted balls), is the number of prize balls paid out according to the number of winning balls and one winning ball. Since it is calculated by multiplying the number of pitches by the number of pitches, it is correlated with the winning rate (number of winning pitches/number of batted pitches). As described above, 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. In addition, each contact 421° 422 . of the variable setting means 42 .
423 may be a relay contact, and the switching may be performed remotely and automatically based on the gaming state, as will be explained later in FIG. 9. Furthermore, as another example of the winning rate variable setting means 42, the resistors R11 to R13 and the contacts 421 to 42
3, the collector of transistor T1 and the power supply (+E
) A variable resistor may be inserted between the output pulse and the output pulse, so that the frequency of the output pulse can be varied over a wide range with the variable resistor. Further, various other modifications of the variable pulse generation circuit 41 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 contact point 42 included in the entry prize rate variable setting means 42
The operation will be described assuming that the resistor R12 is closed and the resistor R12 is selected. The variable pulse generating circuit 41 generates a pulse p1 with a medium constant period (T1), and outputs the pulse p1 to the frequency divider 43.
Give as input to a to 43e. For example, frequency divider 43
If the frequency divider 43a divides the output pulse p1 by 1/10, the frequency divider 43a generates a high level (hereinafter referred to as rHJ) signal every 10 output pulses p1 as shown in FIG. 5(b). and a low level (hereinafter referred to as rLJ) signal are alternately derived and applied to the differentiating circuit 44a. The differentiating circuit 44a differentiates the rising frequency of the frequency-divided pulse q and provides it as an operation command signal for the monostable multi-pulse 45a. Accordingly, the monostable multi 45a derives the output r of the rHJ signal for a predetermined period of time, and A
It is given as one input of the ND gate 46a. by the way,
In the normal state, the pulse oscillation circuit 47 operates for the time required to open and close the beak of the yakumono once (for example, 0.5~
Period (T2) that generates one pulse every 1 second)
A pulse p2 is generated at , and is applied as the other input of AND gates 46a to 46e. 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 the output pulse S
is applied to the transistor 48a, and the transistor 48a is made conductive intermittently by the number of output pulses S. As a result, the solenoid 32a is intermittently energized by the number of output pulses (four times in the figure) of the AND gate 46a, thereby repeatedly driving the beak 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 divided into the corresponding differentiating circuit 44.
Differentiate the rising edge at b~44e to obtain monostable multi 45b~4
5e, and while each monostable multi 45b to 45e derives the rHJ 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), thereby intermittently energizing each solenoid 32b to 32e. , the beak-like portions of each of the yakumono 3b to 3e are repeatedly opened and closed. As mentioned above, the frequency division ratios of the frequency dividers 43a to 43e are selected to differ depending on the installation position of the corresponding Yakumono whose opening/closing is to be controlled.
3e is driven to open and close at different repetition periods. Next, a case will be described in which the payout rate (winning rate) is varied by the switching setting of the input winning 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 the pachinko machine is to be opened to other players after the machine has reached the limit, the staff member must open the manual switch (contact) 422 provided on the back of the game board and close the manual switch 421, or the staff must open the manual switch (contact) 422 provided on the back of the game board, or close the manual switch 421, or open the pachinko machine in the monitoring room. Contact point 4 can be operated remotely from
22 is opened and contact 421 is closed. In addition, if a player is playing pachinko and the pachinko machine has a good ball payout rate and wants to reduce the ball payout rate remotely from the monitoring room,
A staff member operates remotely from the monitoring room to open contacts 422 and close contacts 421. As a result, the variable pulse generation circuit 41 increases the time constant determined by the resistor R11 and the capacitor C1, and thus lowers the frequency of the output pulse p1. Output pulse p of variable pulse generation circuit 41
By lowering the frequency of 1, the period of the frequency-divided pulse output from the frequency divider 43a is delayed, and therefore the phase (period) of appearance of the rHJ signal of the monostable multi 45a is delayed. At this time, since the output frequency of the pulse oscillation circuit 47 and the rHJ signal period (1) of the monostable multi 45a are constant,
The number of repetitions of opening and closing of the Yakumono 3a is a fixed number (4 times in the waveform diagram in Fig. 5), but the rHJ of the monostable multi 45a
Since the appearance phase of the signal is delayed, the result is Yakumono 3a.
The total opening time is smaller than when the contact 422 is closed. Therefore, the probability that a 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, if you want to change the settings to increase the winning rate, open the contact 422 manually or remotely and open the contact 422.
By closing 3, the frequency of the output pulse of the variable pulse generation circuit 41 increases, and the monostable multi 45a~
The appearance period of the rHJ signal output from 45e is accelerated, and the total opening time of Yakumono 3a to 3e 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 an expert can adjust the winning rate.Also, the contact points included in the winning rate variable setting means can be switched remotely, thereby improving the game playability. There is also the advantage that the ball output rate can be easily changed even while the place is open.Also, since the Yakumono is repeatedly opened and closed individually or in groups, it is possible to change the winning conditions for other safe holes etc. It has the advantage of increasing the probability of winning a Yakumono with or without a Yakumono, and improving the service to the players.In addition, since each Yakumono is repeatedly opened and closed for a unit time, it is easy to attract the attention of the players. There is also the advantage that it is possible to increase the interest of the players.In the above-mentioned embodiments, a case is described in which a plurality of yakumono are individually and intermittently repeatedly driven to open and close at irregular intervals. However, only one winning ball device at a predetermined position may be repeatedly driven to open and close.The control circuit shown in FIG. 4A electrically drives the variable winning ball device and A drive control means is configured to variably control the state of the variable winning ball device based on the output of the rate variable setting means. As a modification of the drive control means in FIG. 4A, the Yakumono 3a and 3b are grouped. When driving to open and close repeatedly, frequency divider 43b and differential circuit 44b. AND gate 4 without providing monostable multi 45b.
The circuit may be connected so as to give the output of the monostable multi 45a to the other input of 6b. Similarly, Yakumono 3d and 3e
If you want to group them and drive them repeatedly to open and close, use frequency divider 4.
3e, differentiation circuit 44e. Monostable multi 4 without providing monostable multi 45e
The circuit may be connected so that the output of 5d is given as the other input of AND gate 46e. In addition, as another modification, if it is desired to vary the number of times each Yakumono is repeatedly opened and closed, the rHJ signal derivation periods (i.e., time constants) of the monostable multis 45a to 45e may be selected to be different. Furthermore, as another modification, if it is desired to equalize the period of repeatedly opening and closing the beak-shaped part of the yakumono and the period of rest of the repetitive opening and closing operation, the output of each frequency divider 43a to 43e can be set to the corresponding AND gates 46a to 46e. The circuit may be configured so as to directly provide the other input. Further, instead of the frequency dividers 43a to 43e, an N-ary counter may be used that generates a pulse every time a different predetermined number is counted. Furthermore, if the pachinko game machine is equipped with an electric ball striking mechanism, it will repeatedly open and close for a unit period consisting of each Yakumono only when a player is playing the game, and stop the repeated opening and closing drive when no player is present. If you want to
The pressing output of the batting switch is combined with each AND gate 46a so that the pressing of the batting switch 131 is a condition for deriving the outputs of the ND gates 46a to 46e.
~46e may be commonly given. In this way, when no player is present, the solenoids 32a to 32
Since it is possible to prevent energizing e, the solenoid can be prevented from burning out, which has the advantage of extending the life of the solenoid. Also, if you want to open and close a plurality of machines irregularly and repeatedly based on a certain gaming state during a pachinko game, you can do as follows. for example,
If the combination of identification information displayed on the plurality of variable display members 6a, 6b, and 6c becomes a predetermined combination, the Yakumono can be repeatedly driven to open and close. The circuit may be configured to detect the display state, determine whether a predetermined combination is achieved, and activate the AND gates 46a to 46e when the predetermined combination is achieved. FIG. 6 is a circuit diagram showing another example of the drive control means explained in FIG. 4A. Note that the same parts as in FIGS. 4A and 4B described above 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 generates a pulse p3 having a short rHJ signal period and a long rLJ signal period, and whose period "T3" is variable, as shown in FIG. 7(a), for example. The rHJ signal period is chosen to be the time required to energize the solenoid to open the yakumono. Specifically, the variable pulse generation circuit 6
1 uses a circuit as shown in the above-mentioned FIG. 4B, and rH
Resistors R11 to R are connected so that the J signal period meets the above conditions.
13, the capacitance of the capacitor C1, the resistance value of the resistor R3, and the capacitance of the capacitor C2 are determined, and the resistors R11, R12, R1
3, each resistance value is determined. Then, the output pulse p3 of the variable pulse generation circuit 61 is generated by the AND gates 46a to 46.
It is given as one input of e, and is also given as an inhibit input of AND gate 631, and 1;: A N
It is given as one input of D gates 632 and 633. On the other hand, the pulse oscillation circuit 62 generates a pulse p4 (pulse with a period T4; see FIG. 7(b)) having a constant frequency higher than that of the pulse p3, and supplies it as one input to the AND gate 631. 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 Figure i7 (c)) when the pulse p3 is the rLJ signal and the output of the OR gate 634 is the rLJ signal.
is given to the ring counter 64. This ring counter 6
4 increments the count value every time there is a pulse 95 and cyclically counts the number corresponding to the number of the variable winning ball devices 38 to 3e, and outputs corresponding to the count values 1 to 5. The rHJ signal is derived from the output end corresponding to the count value. Outputs (“H”) derived from each output terminal corresponding to numerical values 1 to 5 of this ring counter 64
signals) are provided as the other inputs of AND gates 46a-46e via corresponding OR gates 65a-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. In a state where the ring counter 64 is counting the number 1 accordingly, the output pulse p3 of the variable pulse generation circuit 61
When becomes the rHJ signal, 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 counting state of the number 1, and the pulse m of the rHJ signal is output from the output terminal corresponding to the number 1.
1 is derived and passed through the OR gate 65a to the AND gate 4.
Give to 6a. At this time, since the pulse p3 is applied to the AND gate 46a, the AND gate 46a derives the output pulse S1 and makes the transistor 48a conductive. This energizes the solenoid 32a, and the variable winning ball device 3a is opened during the rHJ signal period of the pulse p3. Then, when the pulse p3 is reversed to the rLJ signal, the solenoid 32a is deenergized, so the variable winning ball device 3a is closed. By this, 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 the rLJ signal, the AND gate 631 derives the pulse p4 output from the pulse oscillation circuit 62 as the output pulse p5, and supplies it to the ring counter 64. Therefore, the ring counter 64 outputs the output pulse p4 of the pulse oscillation circuit 62.
The count values are sequentially incremented one by one in synchronization with m2., and output pulses m2. m3. m4°m5 is derived, but at this time, since the pulse p3 is an rLJ signal, none of the solenoids is energized, and therefore none of the variable winning ball devices 3a to 3e are opened. Note that, below the waveform of the output pulse p5 of the AND gate 631 shown in FIG. 7, the counted value of the ring counter 64 when the pulse p5 is sequentially applied is shown for ease of understanding. As described above, the AND gate 631 outputs the output pulse p
5, the ring counter 64 cyclically increments its count value. However, when the output pulse p3 of the variable pulse generation circuit 61 is inverted to the rHJ signal, the output of the AND gate 631 is The output pulse m5 corresponding to the count value (for example, 5) that has been inhibited and counted by the ring counter 64 immediately before is applied to the AND gate 46e via the OR gate 65e. For this reason, AN
D-gate 46e derives an output pulse s5 to conduct transistor 48e and energize solenoid 32e. As a result, in the rHJ signal period of pulse p3,
The variable winning ball device 3e is opened, and when the rLJ signal is reversed, 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, when the pulse p3 is at the timing of the rHJ 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. Since it can be easily understood by referring to it, its explanation will be omitted. Thus, in the embodiment of FIG. 6, the ring counter 64
The variable winning ball devices 3a to 3e are irregularly distributed at a timing determined by a combination of the cyclic count value and the rHJ signal output period of the output pulse p3 of the variable pulse generating circuit 61.
Either one of them is controlled to open. By the way, in this embodiment as well, the resistors R11°R12, Rl
By changing the cycle T3 (or frequency) of the output pulse p3 of the variable pulse generation circuit 61 by switching one of the parameters B, the appearance phase (cycle) of the rHJ signal of the output pulse p3 can be delayed or accelerated. Can be done. Therefore, the total opening time of the variable winning ball devices 3a to 3e can be shortened or lengthened, thereby increasing the winning rate (ball output rate).
can be set variably. Note that the pachinko game state (for example, the variable display member 6
Combination status of identification information displayed in a, 6b, 6c)
If you want to group a plurality of variable winning ball devices based on this and open/close them intermittently, you can do as follows. That is, the passage area 2a shown in FIG.
, 2b, 2c, the identification information of the corresponding variable display members 6a, 6b, 6c is variably displayed and controlled, and the combination of identification information of each variable display member 6a, 6b, 6c is displayed in the game. The configuration is such that the state detection means 66 detects the state. When this game state detection means 66 detects a combination of identification information of predetermined variable display members 6a, 6b, and 6c that can open three variable winning ball devices 3a to 3c, it derives an rHJ signal and outputs a flip-flop. (FF)67
Set it to 1. This set output is AND gate 63
2 as the other input of OR gate 6.
34 as the inhibit input of AND gate 631. Therefore, when the gaming state detecting means 66 detects the gaming state, the counting operation of the ring counter 64 is stopped. And every time pulse p3 becomes rHJ signal,
AND gate 632 derives the pulse p3 and OR gates it.
-) Provided as the other input of the corresponding AND gates 46a + 46b, 46c via 65a, 65b, 65c. Accordingly, AND gates 46a, 46b, 46
c makes the corresponding transistors 48a, 48b, 48c conductive during the rHJ signal period of the pulse p3 to control the energization of the solenoids 32a, 32b, 32c, thereby controlling the three variable winning ball devices 3a, 3b. Drives 3C to open and close. At this time, the output pulse of the AND gate 632 is passed through the OR gate 635 to the N-ary counter 6.
given to 8. For this reason, the N-ary counter 68 is configured so that 3
variable winning ball device 3a. When 3b and 3c are driven to open and close simultaneously, a count-up output is derived and the FF 671 is reset. As a result, when the gaming state reaches a predetermined condition, the plurality of grouped variable winning ball devices are driven to open and close. In addition, the game state detection means 66 has two variable winning ball devices 3.
If a condition that allows opening and closing of d and 3e is detected, FF67
2 and derives the pulse p3 via the AND gate 633 and supplies it as one input to the OR gates 65d and 65e, thereby controlling the two variable winning ball devices 3d and 3.
The opening/closing drive of e is performed. In the above explanation, the output frequency of the variable pulse generation circuit 41 or 61 was switched manually or by remote operation by a staff member, but information on the number of profitable balls ( number of winning balls, prize balls, or supply balls) and information on the number of disadvantageous balls (number of batted balls or number of out balls) that is disadvantageous to the player (that is, profit to the amusement park operator) and the relationship (for example, the number of profitable balls). The variable pulse generating circuit 41.6 automatically uses the winning rate variable setting means based on the difference between the number of balls and the number of disadvantageous pitches or the ratio of both.
The output frequency of 1 may be variably controlled. 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.

and will be provided. The setting keys 87 include keys corresponding to the number of stages in the range in which the ball payout rate (or winning rate) can be variably set. For example, assuming that the range in which the payout rate can be variably set is five levels, five setting keys 871 to 875 are provided. The setting key 871 is used to select the lowest ball payout rate (for example, 8
0%), setting key 872 sets the ball output rate to a low rate (for example, 90%), setting key 873 sets the ball output rate to a medium rate (for example, 100%), and setting key 87 sets the ball output rate to a medium rate (for example, 100%).
4 sets the ball output rate to a high rate (for example, 110%), and setting key 875 sets the ball output rate to the highest rate (for example, 120%).
). In this way, when the ball output rate is varied in five stages, five contacts are provided as shown in the above-mentioned FIG.
4, 425 (not shown) correspond to each of the setting keys 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 gaming hall, and a numerical value entered manually 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 according to a preferred embodiment of the present invention. In this preferred embodiment, said contact 4
21 to 425, the operation panel 80, and the arithmetic processing unit 90 constitute a winning rate variable setting means that automatically and variably sets the winning rate (that is, the ball output rate). Next, a case in which the output frequency of the variable pulse generation circuit is automatically variable controlled will be described with reference to FIGS. 4B, 8, and 9. For example, as mentioned above, number keys 871, 872.8
Ball payout rate of 73,874,875 is 80%90%100%
To set it to 110% and 120%, press the setting key 871 and operate the numerical keys 81 to input 80, then press the ball rate setting key 84, press the setting key 872, and operate the numerical keys 81. After inputting 90, press the ball output rate setting key 84, and then press each setting key 873, 8 in the same manner.
Set and input the ball payout rate for each 74.875. The ball payout rate corresponding to each setting key set in this way is stored in the storage area corresponding to each setting key of the processing data storage memory (for example, RAM) 94. In addition, when setting the winning rate, 1 prize per winning ball.
If 5 pachinko balls are to be paid out, set key 87
Press 1 to 875 and operate the numeric key 81 to get the winning rate of 5.3 (%), 6 (%), 6°6 (%), 7.3 (%)
, 8 (%) and then press the winning rate setting key 85. That is, the value obtained by dividing the ball output rate by the number of balls paid out per one winning ball becomes the winning rate corresponding to the ball output rate. The setting keys 871 to 875. Numeric key 81. A target person is given as a target by the winning rate setting key 85 so that the variable winning ball device takes that value. A variable target winning rate setting means is configured to variably set the winning rate. 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, if you want the number 1 pachinko machine's ball output rate to be 100%, the number 2 pachinko machine's ball output rate to be 110%, and the number 3 ball output rate to be 90%, press the machine number key 831. Then, after inputting 1 with the numerical key 81, press the setting key 873, press the machine number key 831, input 2 with the numerical key 81, press the setting key 874, and press the machine number key 8.
After pressing 31 and inputting 3 using the numerical 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 stores the ball output rate corresponding to the operated setting key in the memory area for each machine number of the RAM 94 as the target ball output rate. Written and stored. 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 disadvantageous to the player. Note that the profit information detection means is
As mentioned above, it may be configured with a switch that detects prize balls and supply balls in addition to winning balls. Furthermore, the disadvantageous information detection means may be configured with a sensor that detects out balls in addition to batted balls, as described above. 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 operating panel 80 constitutes a grant rate variable setting means for variably setting the grant rate of the game value to be 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. Output of winning ball detection switch 234 and hitting ball sensor 25 for each pachinko machine
The output of is constantly input to the calculation unit 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). (multiply to calculate the number of prize balls) and calculate the ratio between the number of prize balls and the number of balls hit (in other words, 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 memory (RAM) 93 for storing the ball payout rate.
to memorize each pachinko machine machine number. The arithmetic control unit 91 includes a program storage memory 911 and a timer 912.
The output frequency of the variable pulse generation circuit 41 (or 61) included in the pachinko machine of each machine number is set based on the target ball output rate for each machine number that is preset and stored in 94. For example, the No. 1 pachinko machine has a variable pulse generation circuit 41
By closing the contact point 423 included in the ball output rate (1
00%), the No. 2 pachinko machine closes the contact 424 and sets a high ball payout rate (110%), and the No. 3 pachinko machine closes the contact 422 to set a low ball payout rate (110%). 90%)
Set to . Then, when the timer 912 derives a command signal to reset the ball output rate at a predetermined time, the arithmetic control unit 91 calculates the actual ball output rate of each pachinko machine stored in the RAM 93 in order of each machine number. and the target ball release rate stored in the RAM 94, and it is determined which contact to switch to among the contacts 421 to 425 based on the magnitude relationship between the actual ball release rate and the target ball release rate. Specifically, the arithmetic control unit 91 determines whether, for example, the actual ball payout rate of the No. 1 pachinko machine is the target ball payout rate (
100%) is over or below a range (for example, ±5%), and if it is over, the contact point 423 is opened so that the ball payout rate is one step lower (90%), and the contact point 422 is opened. Close the ball, and if it is below, the payout rate will be one step higher (
110%) and 42
4 is closed. Thereby, it is possible to control the actual ball release rate to approach the target ball release rate. Thereafter, in the same way, the calculation control unit 91 compares the target ball output rate and the actual ball output rate for each machine number, and sets the ball output rate one step higher or lower so as to be closer to the target ball output rate. Switch the contacts 421 to 425 as follows. The arithmetic control unit 91 causes the actual ratio between the total profit information and the total disadvantage information calculated based on the output from the profit information detection means and the output from the disadvantage information detection means to be equal to the target ratio. It has a function of controlling the gaming machine so as to converge. 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. By the way, in pachinko game parlors, in order to know the operating status of each pachinko machine, information such as the number of balls hit, the number of prize balls, and the difference between them is displayed at all times, or the staff in charge specify the machine number. A management device of the gaming hall is provided so that the information is automatically displayed. 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 operates the numerical keys 81 included in the operation panel 80 to input the machine number of the pachinko machine and presses the machine number designation key 831 to specify the machine, and then the ball payout rate is changed. Press any of the desired setting keys 871 to 875 for which you want to change. Accordingly, the arithmetic control unit 91 via the interface 96 operates the contacts 421 to 421 corresponding to the set setting key included in the winning rate variable setting means of the pachinko machine.
By closing any one of the contacts 425 and opening the previously closed contacts, the winning rate can be automatically and remotely variably 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 the player is not an expert such as a seamstress. 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. The operation panel 80 and the arithmetic processing unit 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. You can. In addition, in the above-mentioned embodiment, the case where the payout rate of a pachinko machine is variably controlled as an example of a pinball game machine has been described, but it can also be applied to a coin game machine. For example, if the technical idea of the present invention is applied to a coin gaming machine that awards points according to winning balls to a winning ball device and pays out prizes (coins) based on the number of points, the winning rate of the winning ball device can be improved. By varying the number of points, the points that can be obtained can be set remotely, thereby making it possible to vary the prize payout rate. [Effects of the Invention] In the present invention having the above-mentioned configuration, the ball payout rate can be easily set variably by manual operation, and the variable winning ball device is controlled according to the set ball payout rate. Even non-professionals can easily adjust the ball output rate, and there is no need to adjust the nails formed on the game board surface to adjust the ball output rate. We have now been able to provide a ball game machine.
