Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko gaming machine, and more particularly to a pachinko game machine, in which a plurality of symbols on a symbol change display device are displayed in a variable manner with a prize winning in a starting prize hole, and a ball is added to the starting prize hole while the symbols are changing. When the player wins, the present invention relates to a pachinko gaming machine provided with a storage and display device for temporarily storing the winning of the ball and performing the change of the symbol by the winning ball after the symbol change.

[0002]

2. Description of the Related Art Conventionally, when a ball enters a specific starting winning opening,
When the three rows of symbols of the symbol variation display device are variably displayed so as to flow from top to bottom, and then the symbols are stopped and the predetermined symbols are aligned on a preset determination line, a special game state, ie, a big hit. As a result, a large winning opening of the variable winning device is opened, and pachinko gaming machines for winning many game balls are used in pachinko game arcades in various places.

[0003] In a pachinko gaming machine of this type, when a game ball wins further in the starting winning prize hole while the symbol of the symbol variation display device is changing, the ball won at that time is stored, held and displayed. A special storage display device is provided, and at present, up to four winning balls are stored / reserved and displayed.

[0004] Up to four winning balls won at the time of such a change in the symbol are stored as reserved balls. Therefore, even if five or more balls win at the time of the symbol change, they are not stored, so-called overflow. , And no benefit is given to the player. For this reason, when the number of reserves becomes three or more, it is considered to shorten the fluctuation time of the symbol of the symbol variation display device to speed up the digestion of the reserve ball, or to increase the maximum value of the reserve number. It has been studied to prevent the overflow from four to 255, for example, as the maximum value that can be stored in one byte.

[0005]

However, if the number of prize balls held in the starting winning opening is increased to, for example, 255, the pachinko game arcade requires the customer to enter, for example, on the morning of a business day before starting business. For this service, it is anticipated that an excessive number of balls will be put in the starting winning opening in advance, and it is expected that excessive bargaining will be performed, and a problem that excessively incites the gambling of the player tends to occur.

In the case of a pachinko game machine having a memory backup function, a large number of balls are previously inserted into the start winning prize port of an arbitrarily selected game machine on the morning of the business day of the game arcade, before turning on the power to start business. With the player sitting in front of the pachinko gaming machine, make sure that all the gaming machines are turned on, and for the player sitting in front of the gaming machine that accidentally put the ball, It is expected that a situation in which a jackpot occurs in the game will excessively fuel the gambling spirit of the player and cause excessive bargaining.

[0007] The present invention has been made in view of the above points, and even if the number of prize balls to be held is set to be larger than ever, an excessive service is provided to a player at the pachiko game hall. It is an object of the present invention to provide a pachinko gaming machine that can prevent such a situation.

[0008]

In order to achieve the above object, a pachinko gaming machine according to a first aspect of the present invention is a special symbol display device for displaying a plurality of symbols in a variable manner when a game ball is awarded in a starting winning port. And a special storage display device for holding the winning ball and displaying it when a game ball wins further in the starting winning opening during the variable display of the special symbol display device, and the symbol of the special symbol display device is set in advance. In pachinko gaming machines that are in a jackpot state when stopped in line with the determined arrangement, a normal gaming state and a specific gaming state in which game balls are easier to win than usual in the starting winning opening are set, and the normal gaming is performed. In the state, when a predetermined number or more game balls are won in the start winning port, stop control means for stopping the operation of the gaming machine is provided.

[0009]

In the pachinko gaming machine according to the first aspect of the present invention, in the pachinko game hall, for example, before starting business on the morning of a business day, a store-side clerk may enter a number of winning prize openings for service to customers. When an action such as putting a ball (predetermined number or more) in advance is performed, in the normal gaming state, the stop control means stops the gaming operation of the gaming machine, and the gaming machine cannot be used. Therefore, even with a pachinko gaming machine in which the number of winning balls held in the starting winning opening is increased to, for example, 255, such an excessive service action is prevented, and the gambling of the player is not excessively stimulated. In addition, it is possible to prevent the pachinko parlors from excessively barking.

[0010] In the pachinko gaming machine of the second aspect, the stop control means stops the operation of the gaming machine when the reserved number stored in the special storage display device increases to a predetermined number or more in the normal gaming state. Therefore, even in the case of a pachinko gaming machine in which the number of reserved games is increased, the excessive service action can be similarly prevented.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a front view of a pachinko gaming machine. In the figure, reference numeral 1 denotes a wooden frame of a pachinko machine, and a front frame 2 is mounted in front of the wooden frame 1 via a hinge so as to be openable and closable, and a glass door 5 is provided in front of the front frame 2 so as to be openable and closable.

At the center of the front of the game board 3, a special symbol display device 10 for circulating and moving a plurality of symbols arranged in, for example, three rows in order from top to bottom to display a variation is provided. The special symbol display device 10 displays a plurality of numbers and pictures arranged in three rows on a display 10a such as a color liquid crystal display from the top to the bottom, and optionally displays a moving image of a character or the like below the display. I do. Above the display 10a, a display 15a of the special storage display device 15 is provided by arranging a plurality of lamps and the like.

The special storage display device 15 stores and displays the number of balls (reserved number) that have won the starting winning opening 13 when the symbol fluctuates. For example, a maximum of 255 reserved numbers are stored and displayed. I do. As a display form of the number of held balls, for example, four lamps can be used. When the number of held balls is one to four, each lamp is turned on by that number, and the number of held balls is five. In this case, two lamps are displayed blinking and one lamp is lit and displayed. When the number of reserved lamps is eight, all four lamps are displayed blinking. Further, when the holding number is 9 or more, the display 10
The numerical value is displayed in characters in a.

Above the display 15a of the special storage display device 15, a normal symbol display device 16 is provided. The ordinary symbol display device 16 is configured to circulate and display numerical values of 4, 5, 6, and 7 in order at a high speed, for example, on a one-digit numerical display 16a. Is passed, and when the gate detector 4a detects it, the display 16

On both sides of the display 16a of the ordinary symbol display device 16, the display 17a of the ordinary storage display device 17 is provided with a plurality of lamps and the like arranged. This display 17a
When the gate detector 4a detects a sphere that has passed through the passage gate 4 while the number is fluctuated and displayed on the single-digit number display 16a, the lamp is lit and displayed.

The normal storage display device 17 stores the ball that has passed during the change as a reserved ball. Normally, the variable display of the numbers on the display 16a of the symbol display device 16 stops after a few seconds,
When the stop symbol (number) is a predetermined number, for example, "7", the blade 13c of the start winning port 13 described later is opened for a predetermined number of seconds to make it easier to win a ball. In addition, starting winning opening 13
Indicates that the stop symbol at the time of the jackpot occurrence is a specific symbol,
Even in the specific game state in which the winning probability of the subsequent random number for the jackpot lottery is set higher than usual, the blade 13c is opened for a predetermined number of seconds to facilitate the winning of the ball.

The starting winning opening 13 is a special symbol display 10
, A normal winning opening 12 is provided on both sides thereof, and a variable winning device 11 is provided below the starting winning opening 13. The starting winning opening 13 has openable and closable blades 13c. The blades are driven to open and close by a solenoid 13b, and the prize winning ball is detected by a starting winning detector 14 disposed inside the wing. Variable winning device 11
An opening / closing member 11a that opens and closes a special winning opening is provided so as to be opened and closed by a solenoid or the like.

A special winning opening called a V zone is provided in the big winning opening of the variable winning device 11, and a V detector 19 for detecting a ball winning the specific winning opening is provided inside the special winning opening. A prize detector 18 is provided for detecting a prize ball in the special winning opening. A counter for counting the number of winning ports that have won the winning ports is provided, for example, in a specific memory area or the like of the RAM. One opening of the opening / closing member 11a constitutes one round, and when a specific winning opening is won within a predetermined time, the round is updated, and the opening / closing member 11a is opened up to 16 rounds, that is, 16 times at the maximum.

As shown in FIG. 2, the main control section of the pachinko game machine includes a CPU 20 for executing control processing associated with a pachinko game based on a program stored in advance, a read-only ROM 21 for storing a program of the game, and a data ROM. And a read / write RAM 22 provided with an area for counting the number of winning balls and an area for counting the number of rounds, and an input / output circuit 23.
The RAM 22 is backed up by a backup power supply 24, and supplies power even after the power of the gaming machine is turned off to retain the memory.

When a game ball wins in the starting winning opening 13 during a game, the CPU 20 obtains a random number for a jackpot lottery from a random number generator, performs a jackpot lottery, and determines whether or not the jackpot is determined. Further, the CPU 20 sets the specific game state when the stop symbol at the time of the occurrence of the big hit is a specific symbol, sets the winning probability of the random number for the big hit lottery thereafter to be higher than usual, and sets a predetermined number of seconds. The blade 13c of the starting winning port 13 is opened to facilitate winning of the ball. Further, the CPU 20 sets a state other than the specific game state as a normal game state, and sets the reserved number of winning prize balls of the starting winning opening stored in the special storage display device 15 in the normal game state to a set value (for example, 15 pieces). In the above case, it is determined that there is an abnormality, and the gaming operation of the gaming machine is stopped and controlled.

As shown in the block diagram of FIG. 2, the input / output circuit 23 of the control unit includes a start winning detector 14, a special symbol display device 11, a special storage display device 15, a normal symbol display device 16, a gate detector. 4a, ordinary memory display device 17, winning detector 18, V detector 19, solenoid 1 for starting winning opening
3b and the variable winning device 11 are connected. Further, although not shown, an audio circuit that emits audio and a blinking circuit that blinks a lamp are connected to the input / output circuit 23, although not shown.

Next, the operation of the pachinko gaming machine having the above configuration will be described with reference to the flowchart of FIG. CPU 20
After the power is turned on, the process proceeds to step 100, where it is determined whether or not the winning prize port 13 has been won. If the winning prize port has not been won, the process proceeds to step 140.

On the other hand, when the game ball has won the start winning opening 13, the routine proceeds to step 110, where it is determined whether or not the game state is the specific game state. Here, the current state is the specific game state, that is, the stop symbol at the time of occurrence of the jackpot is a specific symbol, and the winning probability G of the random number for the jackpot lottery is set higher than usual, and the start winning opening is provided for a predetermined number of seconds. When the thirteen blades 13c are released and the ball is in a specific game state in which it is easy to win a prize,
Next, the routine proceeds to step 120. In step 120, while the number of reserves stored in the special storage display device 15, that is, the symbol of the special symbol display device 10 fluctuates, a game ball wins in the starting winning opening 13 and the special storage display device 15 stores the winning ball. It is determined whether or not the number of reserved items is less than the maximum value of 255. If the number is less than 255, the process proceeds to step 130, where 1 is added to the number of reserved items stored in the special storage display device 15, and Go to step 140.

On the other hand, if it is determined in step 110 that the current state is not the specific game state but the normal game state,
Next, the routine proceeds to step 220, where the number of prize balls to be retained stored in the special storage display device 15 is equal to the preset value 15
It is determined whether the number of the winning balls is less than 15 or not.
If the number is less than the number, the process proceeds to step 230, where 1 is added to the number to be stored, and then the process proceeds to step 140.

In the next step 140, it is determined whether or not the number of the held winning balls is one or more. If the number of the held balls is one or more, the symbol change of the special symbol display device 10 is started in step 150. I do. If the reserved number is 0, the process returns to step 100 without performing the subsequent processing. Then, after step 150, the process proceeds to step 160, where 1 is subtracted from the reserved number of winning balls stored in the special storage display device 15,
In the next step 170, based on the acquisition of the random numbers for the jackpot lottery, the symbols in the three rows of the special symbol display device 10 are controlled to stop.

Then, in step 180, it is determined whether or not the symbols for the big hit are aligned on a predetermined determination line.
When the symbols for the jackpot are completed, the process proceeds to step 190, and the process of generating a jackpot is executed. When the big hit occurs, the CPU 20 controls the opening and closing member 11a of the big winning opening of the variable winning device 11 to open and control, for example, a maximum of 9 pieces of the winning set in the variable winning device 11 on condition that the V zone is won. Variable winning device 1 until the winning ball enters the big winning opening
The opening / closing member 11a is controlled to open. Then, on condition that the variable winning device 11 wins in the V zone, for example, a maximum of
The jackpot of the round is executed.

After the jackpot process in step 190, the process proceeds to step 200, where it is determined whether or not a condition for generating a specific game state is satisfied.
If the stop symbol of 0 is a specific symbol and it is determined that the condition for generating a specific game state is satisfied, the process proceeds to step 210, where a specific game state generation process is executed. In the specific game state generation processing, the winning probability of the random number for the jackpot lottery is set higher than usual, and the blade 13c of the starting winning opening 13 is controlled to be opened for a predetermined time, thereby facilitating winning in the starting winning opening.

On the other hand, in the above step 100, it is determined that the ball has won the starting winning opening 13, and in the next step 110,
If it is determined that the game state is not the specific game state but the normal game state, the process proceeds to step 220, and the special storage display device 1
It is determined whether or not the stored number of prize balls stored in No. 5 is smaller than the set value of 15. If it is determined that the number of reserved spheres is 15 or more, the CPU 20 proceeds to step 240
To stop the gaming operation of the gaming machine and disable the subsequent use of the gaming machine.

Therefore, in the pachinko game hall, for example, before starting business on the morning of a business day, a store clerk puts a number of balls (15 or more) in the starting winning opening in advance for service to customers. If an action such as putting in is performed, in the case of the normal gaming state, the process proceeds from step 110 to step 220 and step 240, where the gaming operation of the gaming machine is stopped and the gaming machine becomes unusable. Service acts are prevented.

In the case of a pachinko gaming machine in which the RAM 22 is backed up by the backup power supply 24 as in the present embodiment, an arbitrary selected gaming machine is operated on the morning of the business day of the game arcade before the power is turned on to start business. A lot of balls (15 or more) are put in the starting winning opening in advance, and the player turns on the power of all the gaming machines while sitting in front of the pachinko gaming machine. A player sitting in front of the inserted gaming machine can be provided with a service that creates a big hit from the beginning, but if such an action is taken,
In the case of the normal gaming state, the process proceeds from step 110 to step 220 and step 240, in which the gaming operation of the gaming machine is stopped and the gaming machine becomes unusable, so that such an excessive service is also prevented.

FIG. 4 shows another embodiment. In this embodiment, a predetermined number (for example, 20 pieces) is set within a predetermined time T (for example, one minute).
If the winning ball is held as described above, it is determined that there is an excessive service, and the game operation is stopped.

That is, after the power is turned on, the process proceeds to step 300, where it is determined whether or not the winning prize opening 13 has been won. If the winning prize opening has not been won, the process proceeds to step 340.

On the other hand, when the game ball has won the start winning opening 13, the routine proceeds to step 310, where it is determined whether or not the game state is the specific game state. Here, the current state is the specific game state, that is, the stop symbol at the time of occurrence of the jackpot is a specific symbol, and the winning probability of the random number for the jackpot lottery is set higher than usual, and the start winning port 13 is provided for a predetermined number of seconds. If the wing 13c is released to facilitate the winning of the ball, the process proceeds to step 320. In this step 320, while the number of reserves stored in the special storage display device 15, that is, the symbol of the special symbol display device 10 fluctuates, a game ball wins in the starting winning opening 13, and the special storage display device 15 stores the prize. It is determined whether or not the number of retained balls is less than the maximum value of 255. If the number is less than 255, the process proceeds to step 330, where 1 is added to the retained number stored by the special storage display device 15, and Proceed to 340.

On the other hand, if it is determined in step 310 that the current state is not the specific game state but the normal game state,
Next, the process proceeds to step 420, where it is determined whether or not a predetermined time T (for example, 1 minute) for determining an excess winning is being counted. If not, the process proceeds to step 430, and the count value t is calculated. At the same time as resetting to 0, the counting of the count value t is started, the process proceeds to the next step 320, the above steps 320 and 330 are executed, and the process proceeds to step 340.

In the next step 340, it is determined whether or not the number of prize balls held is one or more.
Next, in step 350, the symbol change of the special symbol display device 10 is started. If the reserved number is 0, the subsequent processing is not performed, and the process returns to step 300. Then, after step 350, the process proceeds to step 360, where 1 is subtracted from the retained number of winning balls stored in the special storage display device 15, and in the next step 370, the special symbol display is performed based on the acquisition of the random number for the jackpot lottery. The symbols in the three rows of the device 10 are stopped and controlled.

Then, at step 380, it is determined whether or not the symbols for the big hit are aligned on a predetermined determination line.
When the symbols for the jackpot have been prepared, the process proceeds to step 390 to execute a process for generating a jackpot. When the big hit occurs, the CPU 20 controls the opening and closing member 11a of the big winning opening of the variable winning device 11 to open and control, for example, a maximum of 9 pieces of the winning set in the variable winning device 11 on condition that the V zone is won. Variable winning device 1 until the winning ball enters the big winning opening
The opening / closing member 11a is controlled to open. Then, on condition that the variable winning device 11 wins in the V zone, for example, a maximum of
The jackpot of the round is executed.

After the jackpot process in step 390, the process proceeds to step 400, where it is determined whether or not a condition for generating a specific game state is satisfied.
If the stop symbol of 0 is a specific symbol and it is determined that the condition for the generation of the specific game state is satisfied, the process proceeds to step 410 to execute the specific game state generation process. In the specific game state generation processing, the winning probability of the random number for the jackpot lottery is set higher than usual, and the blade 13c of the starting winning opening 13 is controlled to be opened for a predetermined time, thereby facilitating winning in the starting winning opening.

On the other hand, if it is determined in step 420 that a predetermined time T (for example, one minute) for judging an excess winning is being counted, the process proceeds from step 420 to step 440.
Based on the ball that has won the starting winning opening in step 300, 1 is added to the count value N of the winning ball. Then, in the next step 450, it is determined whether or not the winning ball count value N is equal to or more than the set value 20. If the winning ball count value N is less than the set value 20, the process proceeds to step 320, where the count value N Is greater than or equal to the set value of 20, it is determined that there has been excess service, and the flow proceeds to step 460 to stop the gaming operation of the gaming machine.

Therefore, in the same manner as described above, in the pachinko game hall, for example, before starting business on the morning of a business day, a store clerk at the start winning prize port at a time (for a predetermined time) for service to customers. A large number of balls (more than 20)
When the player is in the normal game state, the player enters the above-mentioned steps 310 to 420 and step 440.
The process proceeds to 460, and the gaming operation of the gaming machine is stopped and the gaming machine becomes unusable, so that such an excessive service action is prevented.

In the case of a pachinko gaming machine in which the RAM 22 is backed up by the backup power supply 24 as in the present embodiment, an arbitrary selected gaming machine is operated on the morning of the business day of the game hall before the power is turned on to start business. A lot of balls (20 or more) are put in the starting winning opening in advance, and while the player is sitting in front of the pachinko machine, the power of all the game machines is turned on, and the balls are accidentally inserted. The player sitting in front of the gaming machine can be provided with a service that creates a jackpot from the beginning, but if such an action is taken, the gaming machine cannot be used, as described above. Such excessive services are also prevented.

FIG. 5 shows another embodiment of the present invention, which is a measure for preventing excessive service performed when the power of the gaming machine is turned on.
Except for a predetermined number of basic reservations (for example, four), the number of reservations exceeding the number is invalidated to prevent excessive service.

That is, when the power of the gaming machine is turned on,
The CPU 20 first reads backup data from the RAM 22 backed up by the backup power supply 24 in step 500, and executes a game state return process in step 510. This game state return processing includes RA
Processing for resetting either the normal game state or the specific game state based on the stored data of M22, the processing for restoring the reserved number of winning balls stored in the special storage display device 15, and the special game state such as occurrence of a big hit Is reset based on the stored data.

In the next step 520, it is determined whether or not a jackpot has occurred. If not, the process proceeds to step 530 to determine whether or not a specific gaming state has occurred. Here, when the return setting state is not the normal game state but the specific game state, the process proceeds to step 540 to execute the specific game state return processing. In the specific game state return processing, the winning probability of the random number for the jackpot lottery is set higher than usual, and the blade 13c of the starting winning opening 13 is controlled to be opened for a predetermined time, thereby facilitating winning in the starting winning opening. Is performed. Then, the process proceeds to a step 580, wherein a process of restoring the reserved number of winning balls stored in the special storage display device 15 is performed.

On the other hand, if it is determined in step 520 that the state is the jackpot state, the process proceeds to step 570 to execute a process of returning to the jackpot state, perform the sound output for the jackpot and the blinking operation of the lamp, and perform the variable operation. Winning device 1
The opening and closing member 11a of the first big winning opening is controlled to be opened. next,
Proceeding to step 580, the special storage display device 15 re-stores the number of prize balls retained and stores the retained number on the display 15a. Then, the process further proceeds to step 560 to execute a process such as re-storing another game state, for example, re-storing a reserved ball in which the ordinary storage display device 17 stores a ball passed while the ordinary symbol display device 16 fluctuates as a retained ball. Do.

On the other hand, if it is determined in step 530 that the return setting state is not the specific game state but the normal game state, then the process proceeds to step 550, where the special storage display device 1
After resetting the reserved number of winning balls stored in 5 to 0 and invalidating all the retained numbers, the process proceeds to step 560 to perform other game state return processing. As described above, in the gaming machine in which the RAM 22 is backed up by the backup power supply 24, when the power is turned on, the return processing is performed based on the backup data, but in the normal gaming state, the special storage display device 15 holds the winning sphere. Reset the number to 0 and return.

Therefore, for example, on the morning of the business day of the game hall, before turning on the power to start business, a number of balls are put in advance in the winning winning opening of the arbitrarily selected gaming machine, and the player can play the pachinko game. Power on all gaming machines while sitting in front of the machine, and provide a service that creates a jackpot from the beginning for players sitting in front of the gaming machine that accidentally put the ball in However, even if such an action is performed, the reserved number of prize balls stored in the special memory display device 15 is reset to 0, so that excessive service to the customer is prevented, and the joy of the player is reduced. Excessive fanning can prevent excessive bargaining.

In step 550, the process of invalidating the number of prize balls stored in the special storage display device 15 is performed for the number exceeding the four except for a preset minimum number of reserves (for example, four). The reserved number may be invalidated.

[0049]

As described above, according to the pachinko gaming machine of the present invention, a pachinko gaming machine in which the number of winning balls to be reserved can be set more than ever, for example, Before starting, if the store staff performs an action such as putting a large number of balls in the starting winning opening in advance for service to the customer, the gaming operation of the gaming machine is stopped in the normal gaming state As a result, the gaming machine cannot be used, so that such an excessive service action can be prevented.

In the case of a pachinko gaming machine whose memory is backed up by a backup power supply, on the morning of the business day of the amusement arcade, before the power is turned on to start business, a number of prize openings of the arbitrarily selected gaming machine are provided in advance. With the ball in place, with the player sitting in front of the pachinko machine, turn on the power of all the gaming machines, and for the player sitting in front of the gaming machine that accidentally put the ball in It is possible to perform a service that generates a jackpot from the beginning, but if such an action is performed, in the normal gaming state, the gaming machine stops the gaming operation and the gaming machine becomes unusable. Excessive service acts are also prevented, and the player's ambition is excessively fueled, and excessive bargaining action can be prevented.
