Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pachinko game machine, and in particular, an opening provided on a game board of a pachinko game machine to provide a predetermined gaming value to a player. A novel pachinko machine comprising a variable winning ball device equipped with an opening/closing member that can be changed freely between an advantageous first state and a disadvantageous second state that does not provide any gaming value, and in which the drive control of the variable winning ball device is controlled. Regarding gaming machines.

[Prior Art] Pachinko gaming machines (hereinafter referred to as "pachinko machines") that play games using pachinko balls (hereinafter referred to as "balls") have been generally known. Conventional pachinko machines are designed to increase player interest by disposing a Yakumono ball called a chulip and various other variable winning ball devices on the game board. By the way, among players, pachinko machines that have a new variable winning ball device and a new way of driving the variable winning ball device are popular. Therefore, in the pachinko game industry, there is a demand for the development of a pachinko machine that is equipped with a new variable winning ball device and has a new way of driving the variable winning ball device.

[Problems to be Solved by the Invention] Therefore, based on the fact that the ball passes through a predetermined passing area, the variable winning ball device is
The game is controlled so that a relatively small game value can be awarded by driving the variable winning ball device to the state of It is conceivable to control the game so that a relatively large game value can be awarded by driving the variable winning ball device to the first state. In a new pachinko game machine in which the game is controlled in this way, the player first performs a game operation to cause the ball to pass through the passage area that is determined to bring the variable winning ball device into the first state. Then, when a ball passes through the passing area and the variable winning ball device is driven to the first state, a game control state is entered in which a relatively small game value is awarded.
A game operation is performed so that the predetermined specific condition for granting a relatively large gaming value is satisfied, and an attempt is made to generate a gaming control state in which a relatively large gaming value is awarded. and,
When the game control state becomes large, the player attempts to perform game operations so as to effectively utilize the game control state to obtain as large a game value as possible.

However, during the game, the player focuses on the ball being hit onto the game board and is absorbed in adjusting the strength of the ball, so it may be difficult for the player to notice that the ball has passed through the passing area. is expected, and
It is expected that there may be cases where it is difficult to notice that the specific condition has been met. In such a case, after the ball passes through the passing area, the timing of switching the gaming operation for passing through the passing area to the gaming operation for satisfying the specific condition is delayed, and There is an inconvenience that the timing of switching the game operation for establishing the condition to the game operation for effectively utilizing the game control state that gives a relatively large game value is delayed.

In other words, even if a game control state in which a relatively small game value is given and a game control state in which a relatively large game value is given are provided, it is difficult for the player to switch to the game control state. It is difficult to notice this, and there is a delay in switching to a gaming operation that is appropriate for each gaming control state, preventing players from making the most effective use of each gaming control state, and wasting the chance given to them. The disadvantage is that it gets stored away.

In view of the above circumstances, the present invention aims to increase interest by allowing players to enjoy a variety of games through a game control state in which a relatively small game value can be given and a game control state in which a relatively large game value can be given. At the same time, it is possible to prevent a delay in the player's response when switching to the game control state in which a relatively small gaming value can be awarded and the game control state in which a relatively large gaming value can be awarded. An object of the present invention is to provide a pachinko game machine that enables a game that makes full and effective use of a control state.

[Means for Solving the Problems] The pachinko game machine according to the present invention is arranged on the game board of the pachinko game machine, and has an opening with an advantageous first opening that provides a predetermined gaming value to the player.
A variable winning ball device is provided with an opening/closing member that can be changed freely between a state of a passing area defined to enable pachinko balls to pass through the passing area; passing ball detection means for detecting pachinko balls that have passed through the passing area; a specific condition detection means for detecting a specific condition under which value can be added; a display device for displaying a first state of the variable winning ball device; and a display device for displaying a first state of the variable winning ball device in response to an output of the passing ball detection means. At the same time, the display device is displayed in the first display state, and in response to the output of the specific condition detection means, the variable It is characterized by comprising a drive control display means for controlling the game so that a relatively large gaming value can be given by driving the winning ball device to a first state, and for displaying the display device in a second display state. shall be.

[Function] According to the present invention, when a driven ball passes through the passing area, a detection output is derived from the passing ball detection means, and in response to the output, the variable winning ball device is driven to the first state. The game is controlled so that a relatively small game value can be awarded. Further, during the period of the first state of the variable winning ball device, if a specific condition is established, a detection output is derived from the specific condition detection means, and in response to the output, the variable winning ball device is activated to the first state. The game is controlled so that a relatively large game value can be awarded. In other words, a variety of games can be provided to the player through a game control state in which a relatively small game value can be provided and a game control state in which a relatively large game value can be provided.

Moreover, the display device displays the display in the first display state in response to the output of the passing ball detection means, and the display device displays the display in the second display state in response to the output of the specific condition detection means. Therefore, the player
By visually recognizing the first display state of the display device, it is possible to easily recognize the switching to the game control state in which the relatively small gaming value can be awarded, and also, by viewing the second display state of the display device. By visual recognition, it is possible to easily recognize the switching to the gaming control state where a relatively large gaming value can be given, and the switching to the gaming control state where a relatively small gaming value can be given or the switching to the gaming control state where a relatively large gaming value can be given. When switching to a gaming control state where gaming value can be awarded, the player can immediately switch to a gaming operation that suits the respective gaming state, which reduces the delay in the player's response when the gaming control state changes. can be prevented.

FIG. 5 is a game control circuit diagram of an embodiment of the present invention. The game control circuit of this embodiment includes a winning ball detection means 41, a special prize ball detector 42, and a drive control display circuit 50. The drive control display circuit 50 is a first signal generating circuit 5 which is an example of a first signal generating means.
1. It includes an alternate drive control circuit 52 as an example of alternate drive control means, a second signal generation circuit 53 as an example of second signal generation means, and a display drive circuit 54 as an example of display drive means.

The first signal generating circuit generates a signal for opening the variable winning ball device 20 at least once in response to the output of the winning ball detecting means 41. The second signal generating circuit 53 generates a relatively large game after the variable winning ball device 20 is closed in response to the output of the special prize ball detector 42 during the period when the variable winning ball device 20 is open. A signal is generated to repeatedly and alternately drive the variable winning ball device 20 within a certain period (a certain number of opening/closing times or a certain time) in a manner that can give value. The alternate drive control circuit 52 responds to the output of the first or second signal generation circuit 51, 53 to control the variable winning ball device 2.
0 is driven to open and close alternately.

FIG. 6 is a time chart for explaining the operation of FIG. 5, and particularly shows a case where a specific condition is met while the variable winning ball device 20 is being opened in response to a passing ball to the passing area 2c. .

Prior to explaining the operation of this embodiment, an outline of the driving state of the pachinko machine 10 of this embodiment will be briefly explained. When the ball passes through the passing areas 2a, 2b, the first and second opening/closing wings 22a, 22b, 23a, 23b of the variable winning ball device 20 are moved in a manner that gives a relatively small game value. Open and close (for example, open and close only once, open and close for 1 second,
Open until one ball is won). When the ball passes through the passing area 2c, the first and second opening/closing wings 22a, 22b, 23a, 23b are opened and closed in a state where a relatively small game value is given (for example, only twice). Open and close, open for 2 seconds and close, open until 2 balls are won). During the opening of the opening/closing wings 22a, 22b, when a ball hits the winning hole 21a, it is detected that a specific condition that allows a relatively large game value to be awarded is satisfied. In this case, from that point on, each opening/closing wing of the variable winning ball device 20 is driven to open/close in a manner that gives a relatively large value (for example,
The machine will be opened and closed 18 times in a row until the condition of opening and closing 18 times or winning a predetermined number of "10, etc." pachinko balls, whichever comes first, is satisfied.) Then, when a ball wins during the opening and closing of each opening and closing wing, before the opening and closing drive reaches a certain number n (for example, 18 times), the opening and closing drive is performed again a certain number of times from then on. In this way, the specific conditions under which a relatively large gaming value can be awarded are a certain number of times m.
(for example, m=8 times). Therefore, in order to open and close the opening/closing wings 22a to 23b most efficiently, if the opening/closing operation is made to enter the winning hole 21a when the opening/closing operation is a certain number of times, n×m times each. The opening/closing wing pieces 22a to 23b can be opened and closed. On the other hand, in the least efficient case, that is, in the repeated opening/closing operation from the first round to the nth round, the first time (that is, n =
In case 1), if there is a winning ball, the opening/closing drive is performed only m times.

Next, with reference to FIGS. 1 to 6, the specific circuit configuration of FIG. 5 and its operation will be described.

First, a case will be described in which a hit ball passes through the passing area 2a or 2b, or a ball that passes through the passing areas 2a, 2b is guided to the back side of the game board 1 as a winning ball. Winning ball detectors 411 and 412, which are an example of passing ball detection means, are provided in the passing areas 2a and 2b in relation to each other, respectively. For this reason, a winning ball detector (for example, 4
11) derives the detection output and supplies it to the holding circuit 511 via the OR gate 413. Holding circuit 511
stores the fact that a winning ball has been won, and derives a high level until a reset signal is given from a reset pulse generation circuit 515, which will be described later. The high level is applied to the timer 512 and also to the drivers 522 and 523 via the OR gate 521. The timer 512 operates in response to the rise of the output of the holding circuit 511, and measures a predetermined period of time (for example, 0.6 seconds). For a certain period of time set by the timer 512, the driver 5
22, 523 are corresponding solenoids 31a, 31
energize b. In response, the solenoid 31a attracts the plunger, rotates the lever 33a, and pushes down the short side of the lever 34a. Therefore, the long side of the lever 34a rotates in a direction opposite to the center of the variable winning ball device 20. In response, the sliding support member 235 slides to the left of the guide hole 211.
By sliding the sliding support member 235, the opening/closing wing piece 2
As the pin 234 of 3a moves to the left when viewed from the front, the pin 233 moves to the guide hole 2.
13 in an obliquely upward direction. As a result, the opening/closing wing pieces 23a are opened as if the hand is wide open. At the same time, the lever 35a is
4a, and rotates the pin 224 of the opening/closing wing piece 22a diagonally downward along the guide hole 219. Therefore, the opening/closing wing pieces 22a are also opened.

Furthermore, when the solenoid 31b is energized, the right opening/closing wings 22b, 23b are opened in the same manner as the opening/closing wings 22a, 23a on the left.

When the timer 512 times up after a certain time delay, the time-up output is given to the AND gate 514 via the OR gate 513. The output of the holding circuit 531 is inverted and given to the AND gate 514, but at this time,
It is activated because it is not in the detection state of a specific condition. Therefore, AND gate 514 derives a high level and applies it to reset pulse generation circuit 515. The reset pulse generating circuit 515 derives a pulse with a minute time width as a reset pulse, and resets the holding state of the holding circuit 511. As a result, the output of the holding circuit 511 becomes low level, so the drivers 522 and 523
The biasing of 1a and 31b is stopped. In this way, when the ball passes through the passing areas 2a and 2b,
Each of the opening and closing blades 22a to 23b is opened and closed only once.

Next, the operation when the ball passes through the passage area 2c or wins a prize will be explained. In this case, the winning ball detector 41 provided in relation to the passage area 2c
4 derives a detection output as shown in FIG. 6 and supplies it to a holding circuit 516. The holding circuit 516 stores and holds the output of the winning ball detector 414 until a reset pulse is given from the reset pulse generating circuit 515, and derives a high level representing the state. This high level is ORGATE 524
is applied to AND gate 525 via . The output pulse of the frequency divider 526 is applied to the AND gate 525 as the other input. The frequency divider 526 is
It divides the frequency of the output pulse of the clock oscillator 527. From this frequency divider 526, the AND gate 5
The frequency-divided pulse p1 given to No. 25 has a high level period of T1 (for example, 0.8 seconds) and a duty ratio of 50%. Therefore, while the output of the holding circuit 516 is at a high level, the AND gate 525 derives the output pulse p1 of the frequency divider 526 and passes it through the OR gate 521 to the driver 522,
Give to 523. At the same time, the holding circuit path 51
The output of 6 is used as an activation signal by the display drive circuit 542.
and a binary counter 517. The display drive circuit 542 causes the light emitting diodes 27c and 27d to emit light intermittently in synchronization with the period of the output pulse p2 (frequency higher than the frequency of p1) of the frequency divider 526 during the period when the activation signal is applied. The display is displayed to notify that the opening/closing wings 22a to 23b are in the opening/closing operation in a manner that gives a relatively small game value. The binary counter 517 is connected to the holding circuit 5
16, the pulse p synchronized with the output pulse p1 of the frequency divider 526.
Each time 1' is applied, a counting operation is performed, and in response to the application of two pulses, a count-up output is derived and applied to the reset pulse generation circuit 515 via an OR gate 513 and an AND gate 514. Therefore, the reset pulse generation circuit 5
15 is a certain time Td from the rise of pulse p1
(however, T1≦Td≦2T1), a reset pulse with a minute time width is derived, and the holding circuit 516
give to In response, holding circuit 516 releases its memory holding state and sets its output to low level. As a result, the holding circuit 516 controls the AND gate 52
5 outputs a high level until it derives two pulses p1, so the solenoids 31a and 31b
is intermittently energized only twice. Therefore, each opening/closing blade 22a to 23b is driven to open/close only twice, with each opening time being T1 for a certain period of time.

By the way, as mentioned above, each opening/closing wing piece 22
If the ball does not enter the winning hole 21a in a state where a to 23b are driven to open and close once or twice, a specific condition that allows a relatively large gaming value to be awarded will not be detected.

On the other hand, as described above, each opening/closing wing piece 22a~
23b during one or two opening operations,
When the hit ball enters the winning hole 21a, a specific condition is detected and the following operation is performed. That is,
When a ball enters the winning hole 21a during opening of each ball receiving piece 22a to 23b, the special prize ball detector 42 detects it. The special prize condition detection output of the special prize ball detector 42 is given to a holding circuit 531 and also given to a differentiating circuit 532. The differentiation circuit 532 is
The special prize condition detection output is differentiated at the rising edge to derive a pulse with a minute time width. The output pulse of the differentiating circuit 532 is used as a reset pulse for the n-ary counter 53.
3 and is also given to the m-ary counter 534 as an addition pulse. n-ary counter 53
3 is activated while the output of the holding circuit 531 is at a high level, counts the pulse p1' given from the frequency divider 526, and counts up when a certain number n is counted, and before counting the certain number. Even if a reset pulse is applied, the count value is reset. In other words, n
During the period in which the variable winning ball device 20 is in the first state that is advantageous to the player, the advance counter 533
In order to open and close the variable winning ball device 20 only a certain number of times n or less as a game control state that can give a relatively large gaming value, the next special prize ball is set to a certain number n or a number less than a certain number n. It counts the number of openings and closings until it is detected. On the other hand, m
The advance counter 534 counts the number of times a ball hit into the winning hole 21a, that is, the number of special prize balls, in a state where each opening/closing wing piece 22a to 23b of the variable winning ball device 20 is repeatedly opened and closed. The count value of the m-adic counter 534 is determined by the special prize state prohibition circuit 5.
given to 35. The special prize state prohibition circuit 535 is
A setting unit that sets the number of times that one pachinko machine 10 can repeat a specific condition, a comparison circuit that detects when the count value of the m-ary counter 534 has reached the set number m, and a repetition of the specific condition. The number of times is m
and a prohibition circuit for continuously disabling the holding circuit 531 after reaching the number of times.

Next, the operation when there is a specific condition that allows a relatively large gaming value to be awarded, which is a feature of the present invention, will be explained in more detail along the time chart of FIG. 6. In the time chart shown in FIG. 6, when each opening/closing wing of the variable winning ball device 20 is opened twice, the first specific condition is detected, the first advantageous state is given, and the first time When a second specific condition is detected during the n (=18) opening period in an advantageous state, and a third specific condition is detected during the third opening period in the second advantageous state. shows. That is, when the special prize ball detector 42 detects the first specific condition, in other words, the special prize ball that has entered the winning hole 21a, the differentiation circuit 532 differentiates it at the rising edge, and the differential pulse resets the n-ary counter 533. At the same time, the count value of the m-adic counter 534 is incremented by one. At the same time, the holding circuit 531 derives a high level, activates the n-ary counter 533 and the display drive circuit 541, and further applies the high level to the AND gate 525 via the OR gate 524. The output of holding circuit 531 also disables AND gate 514. Accordingly, the AND gate 525 derives the output pulse p1 of the frequency divider 526 and passes it through the OR gate 521 to the driver 522.
and 523. Drivers 522 and 5
23 are the corresponding solenoids 31a and 3, respectively.
1b is intermittently energized in synchronization with the cycle of pulse p1. As a result, the opening and closing wings 22a to 23b of the winning ball device 20 are driven to open and close intermittently. At this time, the n-ary counter 533 counts p1' synchronized with the pulse p1, and counts the number of times each opening/closing blade is driven to open/close under the first specific condition. At this time, the display drive circuit 541 causes the light emitting diodes 27a and 27b to emit light intermittently in synchronization with the frequency division pulse given from the frequency divider 526,
To notify a player that a game control state has been reached in which a relatively large game value can be given. The light emitting diodes 27a to 27d constitute a display device that displays the first state of the variable winning ball device. As described above, when informing the player that a game control state has been reached in which a relatively small game value can be awarded, the first display devices 27c and 27d display (light up or blink). In addition, the second display devices 27a and 27b located at different positions from the first display devices 27c and 27d display (light up or blink) that the game control state is reached in which a relatively large game value can be given.
do. Further, the indication that the game control state has been reached in which a relatively small game value can be given is displayed intermittently by emitting light at a first period synchronized with the period of the output pulse p2. Further, the indication that the game control state has entered into which a relatively large game value can be given is displayed intermittently by emitting light at a second period synchronized with the period of the output pulse p3, which is different from the first period. .

Note that the first display devices 27c, 27d and the second display devices 27a, 27b may be the same, and the light emitting display modes thereof may be changed. Alternatively, the display period may be the same, and only the positions of the first display device and the second display device may be different.

Fortunately, by the time each opening/closing wing piece 22a to 23b was opened a number of times less than the maximum number n, there was no winning ball in the winning hole 21a, and a winning ball was received during the nth opening period. In this case, the second advantageous state operation is performed after the nth opening operation is completed. That is, when the special prize ball detector 42 detects the second special prize condition, the count value of the m-ary counter 534 becomes 2, and the count value of the n-ary counter 533 is reset (=0). At the same time, the differential circuit 5
32 differential pulses are reset pulse generation circuit 51
5, and the reset pulse generating circuit 515 resets the holding circuit 531 for a short period of time.
However, since the output time of the special prize ball detector 42 is selected to be longer than the time width of the reset pulse,
The holding circuit 531 then holds that this is the second specific condition. As a result, the above-described operation is performed again.

Then, in the second advantageous state, during the third opening operation of the opening/closing blades, the ball hits the winning area 2.
When winning 1a, the third specific condition is detected. Therefore, in this case, each opening/closing wing is not repeatedly opened and closed a maximum of n times in one advantageous condition, but completes its opening/closing operation in a relatively small number of three times, and then opens and closes for the third time. We now turn to operation in an advantageous state when a specific condition of is detected.

Thereafter, in the same manner, during n opening/closing operations of each of the opening/closing wing pieces 22a to 23b, in response to a winning ball in the winning hole 21a, the opening/closing operation is performed under the maximum number (n) that can be opened/closed under one specific condition. After being driven to open and close a number of times, the drive is controlled to be in an advantageous state based on the following specific conditions. Then, when the number of circuits generating the specific condition reaches a predetermined constant number (m times), the special prize state prohibition circuit 535 detects this and continuously derives a high level. Since this high level is given as a reset input to the holding circuit 531, the holding circuit 531 will not memorize and hold the specific condition detection state even if there is an output from the special prize ball detector 42 thereafter. The special prize ball detector 42 constitutes a specific condition detecting means that detects a specific condition that can provide a relatively large gaming value when the variable winning ball device is in the first state. Further, the drive control circuit 50 constitutes a specific condition detection means that detects a specific condition that can give a relatively large value during the period when the variable winning ball device is in the first state. Further, the drive control display circuit 50 controls the game so that the variable winning ball device is driven to the first state in response to the output of the passing ball detection means so that a relatively small game value can be awarded. In addition, the display device is displayed in a first display state, and the variable winning ball device is driven to the first state in accordance with the output of the specific condition detection means, so that a relatively large gaming value can be awarded. A drive control display means is configured to control the game and display the display device in a second display state.

As mentioned above, the variable winning ball device 20 used in this embodiment has two winning holes with a step above and below, opening/closing wings are provided on both left and right sides of the two winning holes, and opening/closing of the upper side is provided. Since the length of the ball receiving part of the lower opening/closing wing piece is selected to be longer than the length of the ball receiving part of the wing piece, it is possible to make the ball hit into the winning hole 21b with an extremely high probability, and it is relatively There is an advantage that a game control state can be repeatedly performed in which a relatively large game value can be awarded when a ball is hit into the winning hole 21a with a low probability. This has the advantage that the player can win winning balls with an extremely high probability and can improve the service.

The variable winning ball device used in the above-mentioned embodiment shows a case in which a pair of opening/closing wings are provided on the left and right sides of the two upper and lower winning holes, but the variable winning ball device applied to this invention is The structure is not limited to this, and various other modified structures may be used. For example, it may be possible to have only one pair of opening/closing wings, and to make a part of the ball that can win a prize when the opening/closing wings open be the special prize area. Another modification is to use a variable winning ball device that opens and closes the opening/closing plate on the front of the game board, and makes the part where the balls can be won when the opening/closing plate is opened the special prize area. Good too.

Further, in the above-described embodiment, as a game control state in which a relatively large game value can be given, the opening/closing blades are driven to open and close only n times at most, but the opening/closing operation may be continuous. For example, by setting an advantageous state based on specific conditions at once, up to n・P1/
It is assumed that the game can be opened continuously for only two hours, and in response to a winning ball entering the special prize area within that maximum time, the next specific condition is detected and the next advantageous state operation is performed. Good too. Also,
The special prize area is not limited to a part of the area provided in the winning ball device, but may be a passing area or a winning area formed on the game board, which is adjusted so that it is relatively difficult to win. .

Further, in the above-described embodiment, the game control circuit is configured as a hardware circuit, but a program that performs the same operation may be created and processed by software using a microprocessor or the like.

[Effects of the Invention] The present invention having the above configuration allows players to enjoy a variety of games through a game control state in which a relatively small game value can be given and a game control state in which a relatively large game value can be given. In addition, it is possible to improve the player's interest and reduce the delay in the player's response when switching to the gaming control state where a relatively small gaming value can be awarded or the gaming control state where a relatively large gaming value can be awarded. Therefore, it has become possible to provide a pachinko game machine that allows players to make full use of the chances given to them by preventing the above-mentioned game control states.
