[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to gaming machines, particularly those equipped with a variable display device. [Prior Art] For example, in the field of pachinko gaming machines, in order to improve services to players and expand the number of customers who can enjoy playing, machines are equipped with electrically operated winning devices called yakumono. something is being developed. By adding these accessories, the content of the game becomes more diverse, thereby increasing the wholesome enjoyment of the players. This type of pachinko game machine with accessories is provided with a variable display device and a winning device that operates on the condition that the display content of the variable display device stops in a specific manner. The variable display device forms a type of gaming device within the gaming area of the pachinko gaming machine. This variable display device is activated, for example, when a ball hits a specific winning area provided within the gaming area, and operates to constantly change its display content. This variable display operation that changes the display is stopped by a manual stop operation or when a specific time elapses using a timer. When the variable display operation is stopped, the subsequent display contents are stopped until the next activation. Here, when the displayed content stops in a predetermined specific manner, that is, when the specific aspect occurs, a so-called "big hit" or "mid hit" state occurs. When this "big win" or "medium win" state occurs, the above-mentioned prize entry device operates, and the player is temporarily given a special benefit that dramatically increases the winning probability. As a result, everyone is given an equal opportunity to win a large amount of prize money, and services to players are made fair and impartial. Along with this, the content of games has become more diverse,
It becomes possible to increase the wholesome enjoyment of the players. [Problems to be Solved by the Invention] However, in order to take full advantage of the advantages of the pachinko game machine with accessories as described above, it is necessary to
The stop display contents of the variable display device must be reliably randomized. Otherwise, the fun of the game will decrease and, for example,
Depending on the timing of manual stop operation, etc.
There is a possibility that a negative effect may occur, such as it becoming possible to intentionally increase the frequency of occurrence of the above-mentioned specific aspect. However, the inventor has revealed that if the display update operation of the variable display device is simply randomized using ordinary statistical means, the following problems will occur. Ta. In other words, if the above display update operation is simply randomized using ordinary statistical means, the probability of occurrence of a particular aspect such as a "jackpot" will depend on macro statistics over a very long, almost infinite sample period. If so, statistically speaking, it may be possible for the rates to align at a certain level. However, the probability that the above-mentioned specific aspect will actually occur within a relatively short finite sample period during which the player is playing the game is not necessarily as theoretical.
In fact, it has been found that there is a great deal of variation, and for example, there are cases in which a particular form of "jackpot" occurs continuously, or where the particular form does not occur at all. For this reason, it has been extremely difficult to provide fair services to players. [Object of the invention] This invention solves the above-mentioned contradictory problems at once, and its purpose is to update the display of the variable display device with a very simple and concise configuration. While ensuring randomness in the operation, it is possible to average the probability that the above-mentioned specific aspect will actually appear in a relatively short finite gaming period, thereby making it possible to equalize the service to players. Our goal is to provide a gaming machine that allows you to play. The above and other objects and novel features of the present invention will become apparent from the description of this specification and the accompanying drawings. [Means for Solving the Problems] Representative inventions disclosed in this application will be summarized as follows. That is, in this invention, as a means to achieve the above object, as shown in FIG. 1 with its main configuration correspondingly, the present invention includes a variable display device 4 that forms a game state and updates the display contents of this variable display device 4. In the gaming machine, the display data updating means 02 is configured to provide a special benefit to the player when the display content of the variable display device 4 stops in a specific manner. , a calculation means 01 for adding or subtracting a given value is provided,
Based on the calculation results sequentially obtained from the calculation means 01, the display contents of the variable display device 4 at least when the variable display device 4 is stopped are determined. [Operation] A calculation means 01 for adding or subtracting a given value is provided, and the display content of the variable display device 4 at least when stopped is determined based on the calculation results sequentially obtained from the calculation means 01. By doing so, the display contents of the variable display device 4 can be updated as if at random, and at the same time, a specific number combination that produces a specific form such as a "jackpot" can be made to appear on average at regular intervals. You will be able to do this. As a result, even with a relatively simple and concise configuration, randomness in the display update operation of the variable display device 4 is ensured, and the probability that the above-mentioned specific mode actually appears in a relatively short finite gaming period is averaged. This makes it possible to provide fairer services to players. Furthermore, by selecting the specific value described above, it is also possible to set the probability that the specific mode will appear within a predetermined range. [Embodiments] Hereinafter, preferred embodiments of the present invention will be described based on the drawings. In the figures, the same reference numerals indicate the same or corresponding parts. 2 to 9 show the main body portion of a pachinko game machine to which the present invention is applied. First, the outline and operation of the pachinko gaming machine according to the present invention will be explained with reference to FIGS. 2 and 3. FIG. 2 shows an example of the overall configuration of the pachinko game machine according to the present invention, and FIG. 3 shows an example of the configuration of the gaming area 1a formed on the game board 1. In FIGS. 2 and 3, a ball hitting guide rail 3 is provided on the front surface of the game board 1. The ball guide rail 3 guides the game ball, that is, the ball shot by the ball launcher 2, to the upper part of the game area 1a. The ball launcher 2 is operated and driven by a lower operation dial knob 2a. The game area 1a is formed in a space surrounded by the ball guide rail 3 and the glass plate of the opening/closing panel 101. This gaming area 1a has various winning holes 6a, 6b, 6c, forming a winning area.
7, 8, 53a, winning devices 5, 9, etc. are provided. Along with this, a large number of obstacle nails 11
, various guiding members 12a, 12b, 12c, direction setting members 13a, 13b, etc., are arranged so that the ball hit into the game area 1a falls while changing its direction in various ways. It's getting old. At the lowest part of the game area 1a, an out port 10 is provided for collecting the batted balls that did not win in any of the winning areas to the back of the game board. Further, in the center of the game area 1a, a variable display device 4, which serves as a type of game device, is installed. This variable display device 4 includes segment type displays LEDA, LEDB, and LEDs using light emitting diodes.
Arabic numerals from 0 to 9 are displayed using LEDC and LEDD. When the variable display device 4 operates, the displayed numbers on each of the indicators LEDA to LEDD change respectively. This change is stopped when the player operates stop SW2 or when a certain amount of time has elapsed. At this time, if the combination of displayed numbers after this stop results in a pre-contracted result, a specific mode described later will be generated. The above winning openings 6a, 6b, 6c, 7, 8, 53a
is a fixed winning slot that always has a winning area open. These winning holes 6a, 6b, 6c, 7, 8,
53a, depending on its function, can be used as general prize opening 6a,
6b, 6c, and 53a, and specific winning holes 7 and 8. The batted ball is the general winning hole 6a, 6b, 6c,
53a, a predetermined number (usually 10 to 15) of prize balls will be paid out. When the batted ball enters the special winning holes 7 and 8, a predetermined number of prizes are paid out in the same way as when winning in the general winning holes, and as will be described later, the variable display device 4 is activated. Opportunities for special benefits will be provided. As the winning devices 5 and 9, a ticket type winning device 9 and a special variable winning device 5 are provided. Among them, the special variable winning device 5 normally does not have a winning area, but when a specific mode occurs as a result of the stoppage of the variable display operation in the variable display device 4, a wide area with a very high winning probability is created. Special variable prize opening 80 will be temporarily opened. Furthermore, the special variable winning hole 80 is divided into a normal winning hole 82 which only brings a predetermined number of prize balls, and a continuous winning hole 81 which gives the right to reopen the special variable winning hole 80 in addition to the prize balls. I know. On the other hand, an illuminated central display member 20 is disposed above the game board 1. This illuminated concentrated display member 20 includes a prize lamp 21 that is temporarily turned on when a batted ball enters any winning area;
A turbo lamp 22 that lights up or flashes when a specific mode occurs due to the stoppage of the variable display operation of the variable display device 4, and a special variable prize winning device 5 when a specific mode of "jackpot" described below occurs.
A segment type display LEDE numerically displays the number of times the open state continues, and a completion lamp 24 indicates the completion of the game by the special variable prize winning device 5 when the number of times the continuous state continues reaches a predetermined limit (10 times). It is arranged. Further, the variable display device 4 is provided with lighting means 27 for jackpot display. This lighting means 2
7 is the segment type display device LEDA, LEDB,
Blinks on and off while the display on LEDC and LEDD is changing. Furthermore, when a specific aspect of a "big win" occurs, the blinking speed is controlled to become faster. Thereby, the operation of the variable display device 4 and the occurrence of a "big win" are effectively produced and displayed. Furthermore, a continuation condition fulfillment display section 29 is provided within the special variable prize winning device 5. This continuation condition fulfillment display section 29 is driven to light up when a hit ball enters the continuation winning hole 81 when a specific aspect of a "jackpot" occurs. As a result, it is displayed that a special continuation right to re-open the special fluctuating prize opening 80 has been granted. A firing device drive lamp 26 is provided on the upper part of the holding frame 100 of the pachinko game machine that holds the game board 1 having the above configuration. This firing device drive lamp 26 is turned on when the operation dial knob 2a of the ball firing device is operated. Furthermore, a supply tray 102 is attached to an opening/closing panel 101 attached to the holding frame 100 to hold the batted balls supplied to the batted ball launcher. Furthermore, a saucer 103 for storing prize balls overflowing from the supply tray 102 is provided below. On the side (left side in the figure) of the holding frame 100,
A press-operated stop switch SW2 is provided. This stop switch SW2 is used when it is desired to manually stop the variable display operation of the variable display device 4 activated by the winning hole to the specific winning hole 7 or 8. Now, in the pachinko game machine configured as described above, when a ball hit into the game area 1a by the ball launcher 2 enters any winning area, a predetermined number of balls (usually 10 to 15 Individual)
Prize balls will be paid out. Furthermore, when the winning ball enters the specific winning hole 7 or 8, the variable display device 4 is activated. Then, the four numbers displayed by the segment type indicators LEDA to LEDD of the variable display device 4 can be changed individually. Here, when the player presses the stop switch SW2 or when a certain amount of time has elapsed, the operation of the variable display is thereby stopped. At this time, if the combination of displayed numbers after the stop results in a pre-contracted result, a specific pattern is generated. When a specific situation occurs, the special variable winning device 5 is converted from the closed state to the open state, and a winning area by the above-mentioned special variable winning opening 80 is opened and provided in the gaming area 1a at any time. This changes the probability of winning there from zero to extremely high. As a result, the player is given a special opportunity to generate a large number of winning balls within a relatively short period of time and win many prize balls. In this case, the state caused by the above-mentioned specific aspect is a "jackpot" due to the combination of the above-mentioned displayed numbers.
There are two types: and "medium hit". A "jackpot" state occurs when a specific situation occurs in which all four displayed numbers match one of the predetermined specific numbers. The “medium hit” condition is
This occurs when a specific situation occurs in which any three of the three displayed numbers match one of the pre-contracted specific numbers. In other words, if you get four matches, you will get a "jackpot", and if you get three matches, you will get a "medium hit". If a specific form of “jackpot” occurs,
The special variable prize winning device 5 is set for a relatively long predetermined time (approximately 30
seconds). This dramatically increases the probability of winning a prize. Furthermore, while the special variable winning device 5 remains open, the continuous winning hole 81 set within the special variable winning hole 80
When a hit ball wins a prize, the special variable winning device 5 is once returned to the closed state and then set to the open state again. In other words, the time period during which the special variable winning device 5 remains open is substantially extended. As a result, players are now given many opportunities to win prizes. Further, when a specific mode of "medium winning" occurs, the special variable prize winning device 5 is set to the open state only for a relatively short predetermined time (about 6 seconds). As a result, players are given an opportunity to win significantly more prize balls than would normally be the case, although it falls short of a "jackpot." Here, the combination of numbers displayed on the variable display device 4 is designed to be randomly changed. Therefore, the special opportunities according to the above-mentioned specific aspect are given almost equally, regardless of individual differences in gaming proficiency or the like. As a result, even beginners can enjoy the fortuitous opportunity provided by the above-mentioned specific aspect. However, if the benefits given to the players by the above-mentioned special opportunities are too large, there is a risk that unnecessary gambling will be aroused. Therefore, in order to avoid stirring up the gambling spirit, the following control operations are also performed in the control operations related to the occurrence of the above-mentioned specific aspect. That is, when the above-mentioned "jackpot" state occurs, when the number of winning balls to the special variable winning device 5 reaches a certain limit number (10 balls), the special variable winning device 5 waits for a predetermined time (approximately). 30 seconds), it can be forced to return to the closed state immediately. Furthermore, the number of times the continuous winning opening 81 is set to remain open due to winnings is set to a certain number of times (10
times) are now limited to the following: In this way, the healthy interest of the players is not spoiled, and unnecessary speculation is not aroused. On the other hand, although it is omitted to illustrate, when a specific mode such as a "big hit" or "medium hit" occurs, in addition to the above-mentioned control operation, depending on the type of the specific mode, for example, a sound effect such as Juan Juare, etc. Control of the performance display using sound is also performed. Note that the sound effects such as "fanfare", which will be described in detail later, are electronically generated and emitted from a speaker (not shown) built into the gaming machine. Such presentation displays allow players to experience fun things other than winning prize balls. Next, the configuration of the pachinko game machine described above will be explained in more detail with reference to FIGS. 2 to 9. FIG. 2 shows the front of a pachinko game machine to which this invention is applied. As described above, the pachinko game machine whose outline is shown in the figure includes a game board 1, a ball launcher 2, a dial knob 2a for operating a ball, a ball guide rail 3, a holding frame 100, an opening/closing panel 101, a supply tray 102, It has an overflow ball tray 103 and the like.

The center of the game board 1 is largely surrounded by a ball-hitting guide rail 3. A gaming area 1a is formed within this surrounding area. Furthermore, an illuminated central display member 20 is set at the top of the game board 1. This concentration display member 20 integrally includes a prize ball lamp 21, a specific mode occurrence display lamp 22, and a completion lamp 24. Further, a segment type display LEDE made of light emitting diodes is attached to the concentrated display member 20. The functions of these lamps and indicators are as described above. That is, the prize ball lamp 21 is temporarily turned on when a ball hits the winning area. The winning area is provided by, for example, a ticket-type winning device 9 or the like. The specific mode occurrence display lamp 22 is lit or blinks when a specific mode such as a "medium hit" or "big win" occurs. The segment type display LEDE numerically indicates the number of times that the open state of the special variable winning device 5 is continued/extended due to a hit ball winning the continuous winning hole 81 when a predetermined form of “jackpot” occurs. indicate. The completion lamp 24 notifies the completion of the game by the special variable prize winning device 5 when the number of continuations and extensions reaches a predetermined limit (10 times). The ball firing device 2 is electrically driven and fires the game balls in the supply tray 102 one by one. This operation is performed by rotating the dial knob 2a. The dial knob 2a is rotated manually and is configured to automatically spring back to a non-operating position when the player releases his/her hand. The ball guide rail 3 is a game area where the game ball, that is, the ball shot by the shooting device 2 will be described later.
Guide within 1a. As described above, the game area 1a is formed on the front side of the game board 1 surrounded by the ball hitting guide rail 3. In this game area 1a, there are a large number of obstacle nails 11 that randomly change the direction of the ball, and a transfer guide member 12 that controls the falling speed and direction of the ball.
a, 12b, 12c, etc. are arranged. Along with this, in the game area 1a, there are various winning devices that provide winning areas, namely, a special variable winning device 5, a first predetermined winning hole 7, a second winning hole 8,
A ticket type winning device 9 and the like are provided. As described above, the special variable winning device 5 is configured to operate and temporarily open a winning area when a specific aspect of the variable display device 4 occurs. An example of the configuration of this special variable prize winning device 5 will be explained in detail later. Moreover, the first and second specific winning holes 7 and 8 are adapted to provide a specific winning area for activating the variable display device 4, as described above. Further, within the gaming area 1a, a variable display device 4, an exit 10, lighting means 25, etc. are arranged. Although the details will be described later, the variable display device 4 is configured to variably display a plurality of types of characters in each display window section at a plurality of display window sections (four locations). In this embodiment, Arabic numerals from 0 to 9 are variably displayed as characters. The results of the displayed numbers are changed randomly. The out port 10 collects batted balls that could not enter any of the winning areas in the game area 1a, that is, missed balls that could not win. The illumination means 25 blinks or lights up when a specific mode occurs due to the stoppage of the variable display operation of the variable display device 4. On the other hand, the holding frame 100 forms the outer frame of the pachinko game machine. This holding frame 100 includes the above-mentioned stop switch SW2 and firing drive lamp 2.

Reference numeral 2 is for manually stopping the variable operation of the variable display device 4, and is constructed using a push-operated (button type) momentary type (synchronizing type) switch. The overflow ball receiving tray 103 is a place where balls overflowing from the supply tray 102 are stored. When a batted ball wins a prize, a predetermined number of prize balls are paid out, and these paid out prize balls are discharged into a supply tray 102. FIG. 3 shows details of the game board 1. In FIG. 3, above the variable display device 4, three general winning openings 6a, 6b, and 6c, so-called "heaven,""heaven'sleft," and "heaven's right" are integrally provided. In addition, these general prize openings 6a, 6b,
6c may be provided independently apart from the variable display device 4. In addition to the rolling guide members 12a, 12b, 12c, etc., first and second direction establishing members 13a, 13b are arranged in the upper half of the game area 1a. These direction setting members 13a, 13b are formed by obstruction nails. Below these direction setting members 13a, 13b is the rolling guide member 1.
2a, 12b, and 12c are provided, respectively. Of those rolling guide members, the first
The rolling guide member 12a has its rotation axis slightly closer to the center from diagonally above the first specific winning opening 7, and further than the center line of the first direction setting guide member 13a located above it. It is pivoted outwardly by a distance A. The second rolling guide member 12b is located slightly below the inside of the first specific winning opening 7, and is located slightly below the center line of the distance between the second direction setting guide member 13b and the shoulder portion 4a of the variable display device 4. It is pivoted outwardly by a distance C. As a result, the direction of the hit balls that have flowed down toward the rolling guide members 12a and 12b is controlled so that they tend to flow down toward the center of the game board. Here, winning balls entering the first and second specific winning openings 7 and 8 are guided on a different route behind the game board 1 from winning balls entering other winning areas. And the third
The start switch whose installation position is shown by the dotted line in the figure
After converting SW1 into currency, it is now possible to join other winning balls into the common guidance route. The start switch SW1 is installed in the passage path of the batted ball that has won the specific winning hole 7 or 8, and thereby detects the specific winning ball. The variable display device 4 is activated by this detection signal. The variable display device 4 has a shoulder portion 4a with a second end.
The lower end of the direction setting guiding member 13b is also set at a position that is a distance B higher than the other end. As a result, the batted ball that has flowed down along the second direction setting member 13b and the shoulder 4a of the variable display device 4 passes through the AC surface (described later) of the variable display device 4 and reaches the second specific location below. It is designed to make it easier to jump into the prize opening 8 and the special variable prize winning device 5. As described above, the direction setting guiding member 13a,

5 is fixed so as to form an arc continuous with the ball hitting guide rail 3. A riot prevention member 16 is attached to the upper end of this ball guide member 15.
This riot prevention member 16 acts to suppress the violence within the game area by suppressing the momentum of the ball hit at high speed. FIGS. 4 and 5 show in detail a specific example of the configuration of the variable device 4 described above. The variable display device 4 is fixed to the game board 1 with a mounting hole 44 shown in FIG. 4 and screws 43a or nails 45 shown in FIG. 5. At the top of the variable display device 4, as shown in FIG. 5, a guiding plane 40b is integrally formed with a decorative plate 40a that covers the front thereof. This guiding plane 4
0b is formed to protrude forward from the surface of the game board 1. As shown in FIG. 4, an arched shoulder 4a is provided at the upper end of the guiding plane 40b.
This shoulder portion 4a acts to slow down the speed of the hit ball flowing down from above the game board and to smoothly distribute the hit ball to either the left or right game area. On both sides of the lower end of the guiding plane 40b are downward guiding inclined surfaces 40c which are inclined downwardly toward the inside.
is formed. This guiding inclined surface 40c allows the ball to be easily guided to the inner surface of the exchange surface 41. Furthermore, an AC surface 41 is formed below the guiding plane 40b. The AC surface 41 is substantially flush with the surface of the game board 1, as shown in FIG. This allows interaction of batted balls flowing down the left and right game areas through the interaction surface 41. As a result, the ball can easily fly into the second specific winning hole 8 or the special variable winning device 5 described above. As shown in FIG. 5, a recess forming wall 42 is fixed to the exchange surface 41. As shown in FIG. This recess forming wall 42 is fixed by a fastening part 41a and a screw 43, and constitutes a recess 42a that goes deep into the game board 1. A mounting surface 46 for mounting a variable display member 47, which will be described later, is provided at the back of this recess 42a. As shown in FIG. 4, the mounting surface 46 has three
The display windows 46b are formed in a horizontal row.
Further, as shown in FIG. 5, a support for fixing the variable display member 47 is provided protruding from the back thereof. As shown in FIG. 5, the variable display member 47 is attached and fixed behind the mounting surface 46 even when it is attached to the substrate 47a. As shown in FIG. 4, this variable display member 47 has three indicators arranged in a horizontal row. In this embodiment, as shown in FIG.
LEDB and LEDC are used. Each display
LEDA, LEDB, and LEDC are each positioned so as to face the display window 46b of the mounting surface 46. Further, as shown in FIG. 4, the guiding surface 40b
A display window 40d is also formed in the center of the display window. Another variable display member 48 is attached behind this display window 40d. This variable display member 48 has one indicator LEDD. This indicator LEDD is also a segment type indicator using light emitting diodes. As shown in FIG. 5, this variable display member 48 is positioned and fixed together with its mounting board 48a by screws 43d. Here, the above segment type display LEDA,
LEDB, LEDC, and LEDD are each a type of character display element, and are configured so that a plurality of types of characters can be arbitrarily and variably displayed by combining segments that are driven to emit light. In this example, as the character,
Arabic numerals from 0 to 9 are used.
Therefore, the above segment type display LEDA,
LEDB, LEDC, and LEDD are configured such that each display can display any number from 0 to 9 depending on the combination of its segments. Note that the above-mentioned character may be characters other than numbers, a symbol mark, a picture, or the like. Furthermore, as shown in FIG.
At the bottom of the game, four memory display lamps LED1 to LED4 are arranged in a row horizontally to display the number of batted balls that have won in the aforementioned specific winning openings 7 and 8 (FIGS. 2 and 3). These memory indicator lamps
As shown in FIG. 5, the LEDs 1 to 4 are exposed through a through window 42d formed at the bottom of the recessed wall 42. As described above, the variable display member 47 and the memory display lamps LED1 to LED4 are all arranged at a position set back from the game board 1 surface. This is because the display member on which the variable display member 47 and the memory display lamps LED1 to LED4 appear is an alternating current surface, and the exchange of balls occurs frequently, so this is to protect them from being hit by the ball and prevent them from being damaged. It's for a reason. In addition, in order to widen the visual range in which the variable display member 47 can be seen from the front, the recess forming wall 4
The variable display member 47 is tilted in a widening shape from the back toward the front side, and its inner wall surface is plated so that the display contents of the variable display member 47 can be clearly displayed.
Furthermore, the inner surface of the recess 42a formed by the recess forming wall 42 allows the external incident light to reflect on the surface and enter the player's field of view, so that the variable display member 4
In order to avoid obscuring the display of number 7, it is tilted slightly upward (approximately 8 to 10 degrees) with respect to the vertical plane. On the other hand, on both sides of the guiding plane 40b, a fourth
As shown in the figure, a pair of jackpot display illumination means 27 made of semi-transparent colored members are provided. A lamp (not shown) which is a light source of this jackpot display illumination means 27 is mounted inside the illumination means 27 using a mounting board 27a and screws 43c, as shown in FIG. Although not shown, the mounting board 27a is attached to a post protruding from the back side of the board of the variable display device 4 via a cushion material so as to improve ventilation. This makes it possible to absorb vibrations caused by the light source lamp and to efficiently dissipate heat generated from the lamp. The variable display device 4 configured as described above is activated (triggered) by the start switch SW1 (FIG. 3) which detects winning balls entering the specific winning holes 7 and 8. When the variable display device 4 is activated, the four indicators LEDA, LEDB, and the variable display members 47 and 48 disposed inside the variable display device 4 are activated.
The display contents of LEDC and LEDD can be changed from a static state to a fluctuating state. And each indicator LEDA,
For each LEDB, LEDC, and LEDD, the displayed numbers will change (update) regularly like 0, 1, 2, 3, . . . 9, 0, 1, 2, . . . In this state of fluctuation display, the stop switch SW
2 (Figure 2), or after a certain amount of time has passed since the state of fluctuation, each indicator LEDA, LEDB, LEDC, LEDD
The changes in the displayed numbers are stopped in order at regular intervals. Then, the state returns from the fluctuating state to the stationary state. If the four numbers that appear on each display LEDA, LEDB, LEDC, and LEDD when this display stops changing are in a specific combination (roll), this will give a special benefit. is generated. In this embodiment, for example, all the numbers on the variable display member 47 are "1", "3", "5",
If you get ``7'' or ``9'', that is, if you get the same number (zorome), you win the jackpot.
The first specific aspect is called. In addition, when any three of the four numbers on the variable display members 47, 48 become "1", "3", "5", "7" or "9", " The second specific mode is called "mid hit". For other rolls, the specific aspect will not occur. On the other hand, the jackpot display irradiation means 27 on both sides of the variable display device 4 are connected to the variable display members 47 and 48.
While the display is changing, it is driven to blink. Furthermore, if a "big hit" or "medium hit" state occurs at the time when the display members 47, 48 stop changing, the blinking speed is controlled to become faster. In addition, a memory display lamp at the bottom of the variable display device 4
LED1 to LED4 are controlled to light up as many times as the number of reservations on the variable display section. 6 to 9 show detailed configuration examples of the special variable prize winning device 5 shown in FIGS. 2 and 3. The special variable prize winning device 5 shown in the figure first has a mounting board 50 for mounting on the game board 1.
This mounting board 50 can be mounted to the game board 1 by using mounting holes 54 provided on its periphery. As shown in FIG. 7, a horizontally elongated opening 50a is formed in the center of the mounting board 50. As shown in FIG. Immediately below this opening 50a is a window 50b.
is formed. Moreover, as shown in FIG. 6, this opening 50a accommodates a door-shaped special variable winning opening 51 that can be opened and closed. Further, a board 52 is attached behind the mounting board 50, as shown in FIGS. 6 to 8. This substrate 52 is attached so as to cover the opening 50a from the back side. This back plate 52 has
As shown in FIG. 8, an opening window 52b corresponding to the center of the opening 50a is punched out. Further, on the back side of the mounting board 50, as shown in FIGS. 6 to 8, a surrounding frame 54 is integrally formed. As shown in FIG. 8, the surrounding frame 54 extends from the upper edge of the opening 50a to the window 5.
It is formed along both left and right edges of 0b. The substrate 52 is fixed to the rear end of the surrounding frame 54 with screws 55. Further, on both sides of the enclosing frame 54, eighth
As shown in the figure, a winning ball guiding gutter 54a is formed. This winning ball guide gutter 54a is connected to the mounting board 5
It is formed at a position corresponding to the front surface of 0 and a pair of winning devices 53. Then, the winning hole 53a acts to guide the winning batted ball to the back of the game board. Furthermore, winning devices 53 are separably mounted on the left and right sides of the mounting board 50, respectively. Each winning device 53 includes a rotating member 70 and a proving means 53, as shown in FIGS. 6 and 7, respectively.
b is provided. The winning device 53 also has a winning opening 53a that opens upward at the upper end of the winning device 53.
are provided for each. This winning hole 53a constitutes a general winning hole as described above. Further, as shown in FIG. 8, through holes 50e are formed in the mounting board 50 at positions corresponding to the pair of winning devices 53. A proving lamp 28 serving as a light source for the proving means 53b is inserted into this through hole 50e. The verification lamp 28 is mounted and fixed to the boss portion 50f on the back surface of the mounting board 50 while being mounted and fixed to the board 28a via the socket. Its installation/
Fixing is performed using the mounting hole 28b of the board 28a and the screw 28c. Here, the special variable winning slot 51 is opened and closed in response to a specific aspect of the variable display device 4, and as shown in FIG. It is attached so that it can be opened and closed in the front and rear directions. This special variable winning slot 51
When the opening, as shown in FIG. 7, a special variable winning opening 80, which is much wider than the general winning opening, is temporarily opened. In this special variable winning hole 80, there is a normal winning hole 82 that brings only the normal winning profit of paying out a predetermined number of prize balls, as well as a continuous winning hole that brings the right to continue and extend the above-mentioned specific mode. A mouth 81 is formed. In addition, one side of the special variable winning slot 51 (the seventh
An actuating piece 51a is formed on the right side in the figure. The end of the actuating piece 51a projects from a long hole 52a formed in the back plate 52 to the back side of the base plate 52. Then, it is adapted to be engaged with an electromagnetic solenoid, which will be described later, via a transmission member 65. As a result, the special variable prize receiving slot 51 is driven to open and close via its operating piece 51a. FIG. 6 shows a state in which the special variable winning hole 51 is raised rearward, thereby closing the special variable winning hole. FIG. 7 shows a state in which the door-shaped special variable winning hole 51 is folded forward to open the special variable winning hole. On the other hand, a window portion 50 is provided on the back side of the mounting board 50.
A pair of winning ball guiding members 56a and 56b having a substantially L shape are formed along the lower edge of the ball. Each tip of the pair of winning ball guiding members 56a, 56b is
They are placed opposite each other at a distance of approximately one sphere. Further, an engagement recess 57a is formed at the tip of one of the winning ball guide members 56a. Along with this, an engaging portion 57b is formed below the base end side of the other winning ball guiding member 56b. A detector SW4 for detecting and calculating the number of winning balls into the special variable winning hole 80 is mounted and held by the engaging portion 57b and the engaging recess 57a. This detector SW4 is a so-called 10-count detector, and a non-contact type proximity switch is used here. This 10-count detector SW4 is mounted so that the detection portion 31a at its tip faces within the space between the tips of the guide members 56a and 56b. Thereby, this detector SW4 can detect the winning balls guided by the guiding members 56a and 56b one by one. Further, as shown in FIG. 7, a sorting room 58 is formed within the special variable prize opening 80. This sorting room 58 is surrounded by the surrounding frame 54 (FIG. 8) on its top, bottom, right and left, and by winning ball guide members 56a and 56b (FIG. 8) on its lower side. The winning balls that have entered the sorting room 58 are transferred to the winning ball guiding member 56
The particles are aligned and guided by the actions of a and 56b, and are made to flow down one by one passing through the detection section 31a of the 10-count detection section SW4. After passing through the detector 31a, the winning ball is guided to one side (to the right in FIG. 8) by an arcuate direction regulating portion 50d shown in FIG. The arc-shaped direction regulating portion 50d is integrally formed at the lower part of the back surface of the mounting board 50, as shown in FIG. Here, on the front surface of the back plate 52, as shown in FIG. 7, a pair of guide plates 52c are formed on both side edges of a window 52b formed in the center thereof. By this guide plate 52c, the upper part of the sorting room 58 is divided and separated into the above-mentioned continuous winning opening 81 and normal winning opening 82. Further, on the back surface of the back plate 52, as shown in FIG. 8, a support protrusion 52d is formed along the upper end of the opening window 52b on the back surface. A sensing piece 60 is swingably suspended from the support protrusion 52d via a pin 59. This sensing piece 6
0, the opening window 5 is swingably hung down.
It is urged to go in and out of the continuation prize opening 81 shown in FIG. 7 from inside 2b. As a result, the batted ball that enters the continuation winning slot 81 (Fig. 7) is guided by a pair of guide plates 52c, as shown in Figs. 7 and 8, and forwards from the rear opening window 52b. After rotating the sensing piece 60 protruding backward, the sensing piece 60 flows downward toward the detection part 31a of the 10-count detector SW4, where it is detected one by one along with the batted balls that have won in the normal winning hole 82. It is starting to be counted. As shown in FIG. 8, the sensing piece 60 is a continuation condition detection switch SW consisting of a micro switch.
Due to the elasticity of the actuator 32a of No. 3, the actuator 32a is weakly elastically biased so as to protrude forward from the opening window 52b. This continuation condition detection switch SW3 is for detecting a hit ball that has won in the continuation winning slot 81, and is attached to the back plate 52 via an L-shaped attachment member 61. The continuation condition detection switch SW3 is positioned such that its actuator 32a comes into contact with a pressing portion 60a bulged on the back surface of the sensing piece 60.
The upper end of the sensing piece 60 is formed with a pin hole 60b into which the pin 59 is inserted, and a stopper portion 60c that projects rearward to restrict the range of rotation of the sensing piece 60. Further, the support pin 59 of the sensing piece 60 that is engaged with the support protrusion 52d is connected to the pressing member 6.
It is prevented from coming off by fixing the rotation regulating portion 62a integrally formed on the support projection 52d to the support protrusion 52d. Further, the continuation condition fulfillment display section 29 is inserted into the slit section 62d on one side of the holding member 62. This continuation condition fulfillment display portion 29 is held and protected by a protection member 63 fixed to the boss portion 62c of the presser member 62. The batted ball that enters the continuation winning slot is placed in the opening window 52.
d, it passes while pushing away the sensing piece 60. During this passage, the continuation condition detection switch SW
3 is activated and a detection signal is emitted for each ball. After this, along with the batted ball that won the normal winning hole 82, the detection unit 3 of the count detector SW4
They are guided to 1a and detected one by one. Further, as shown in FIG. 8, a continuation condition fulfillment display section 29 is attached to the back plate 52. This continuation condition fulfillment display section 29 is arranged so as to face into the opening window 52b. This continuation condition fulfillment display section 29 is driven to light up in response to a detection signal from the continuation condition detection switch SW3. This allows the player to know the establishment of the special conditions under which the right to continue or extend the specific aspect described above is granted. Further, as shown in FIGS. 8 and 9, a pair of boss portions 52f are formed on both sides of the elongated hole 52a on the rear surface of the back plate 52. As shown in FIGS. This boss 52
As shown in FIG. 9, at f, a support shaft 65a of the transmission member 65 is supported by a mounting piece 64 so as to be movable up and down. The transmission member 65 has a "h" shape. Its tip portion projects forward from the elongated hole 52a. Furthermore, the transmission member 65
The tip of the actuating piece 51c is adapted to come into contact with the upper surface of the rear end of the actuating piece 51c. This operating piece 51c is formed in the special variable prize receiving hole 51 (FIG. 7). Furthermore, the upper end of the transmission member 65 is in contact with the operating end of a plunger 66a of an electromagnetic solenoid SOL. This electromagnetic solenoid SOL serves as a driving source for the special variable prize winning device 5. In FIG. 9, when the electromagnetic solenoid SOL is in a non-driven state, the plunger 66a is pushed down by its return spring 66b, thereby pushing the transmission member 65 downward. Then, as imagined by the dotted line in Fig. 9, the actuating piece 5
The rear end side of 1c is pushed down to close the special variable winning slot 51. As a result, the opening 50a is closed, and therefore the special variable prize opening 80 is also closed. On the other hand, when the electromagnetic solenoid SOL is energized by the occurrence of a specific mode in the variable display device 4 or the right to continue, the plunger 66
a is driven upward. As a result, the pressing force of the transmission member 65 is released, and the special variable prize receiving slot 51 falls forward under its own weight. As a result, the opening 50a is opened wide, and the special variable prize opening 8
0 will be created temporarily. As described above, the special variable prize winning device 5 is electrically opened and closed depending on the occurrence of a specific mode in the variable display device 4 and the above-mentioned right to continue. Next, an embodiment of a control portion of a pachinko game machine to which the present invention is applied will be shown. FIG. 10 shows the overall hardware configuration of a control device 100 for a pachinko game machine according to the present invention. FIG. 11 shows the waveform of the reset pulse φt and the operating state of the CPU 210 using a timing chart. FIG. 12 shows means for generating the reset pulse φt. FIG. 13 shows details around the I/O unit 240 of the control device 200. FIG. 14 shows the configuration of the scale generating means 260 within the I/O unit 240. First, in FIG. 10, the control device 200 of the pachinko game machine 300 described above is configured using a program storage type CPU (central processing unit: microcopy computer) 210 that is implemented as a semiconductor integrated circuit device. That is, the control device 200 shown in FIG.
CPU 210, ROM (read-only storage device) 22
0, RAM (Random Access Memory) 23
0, address recorder 240, I/O (input/output)
unit 250, clock signal generating means 280,
Reset signal generating means 290, address bus LA,
It is composed of a data bus LD, a logic gate G1, and the like. The CPU 210 is an 8-bit type (model number: Z80). This CPU210
are address terminals A ₀ to A ₁₅ , data terminals D ₀ to _{D 7} ,
Read control terminal RD, write control terminal WR, clock
It has functional terminals such as CK and reset terminal R. Other important functional terminals include an interrupt input terminal (not shown). However, the interrupt terminal is not used here. Instead, a reset terminal R is used. How to use the reset terminal R will be described later. In addition, the CPU 210 used here
(Z80) by 16 address terminals _A0 to _A15 .
It has an address space of 64k bytes. However, only about 2k bytes of that data is used here. The ROM 220 stores programs executed by the CPU 210 and fixed data. this
The ROM 220 used has a storage capacity of 2 kbytes. This 2k byte capacity is CPU2
Compared to the address space of 10 (Z80), which is 64k bytes, the capacity is extremely small. The RAM 230 provides a work area for the CPU 210 and a variable data storage area. A static type ROM 230 is used. Its storage capacity is kept very small, only 128 bytes. In this case, since 128-byte ROM is difficult to obtain, 1k-byte ROM is actually used. By fixing the upper address terminal of this 1k byte RAM to the power supply potential side, the actual usable storage capacity is kept to 128 bytes. As mentioned above, ROM220 and RAM23
The storage capacity of each 0 is kept very small. This makes it possible to reliably eliminate the possibility of soft errors known as bugs, and also to reduce the possibility of malfunctions such as CPU runaway or jumping into an infinite loop. This can be significantly reduced. This makes it possible to obtain extremely high reliability even under electrically and physically harsh operating environments. Furthermore, by minimizing the storage capacity of the ROM 220 and RAM 230, it becomes difficult to modify the system by adding additional programs. Even if a modification were made, it would be easy to discover and check because the storage capacity is small. This makes it possible to prevent the pachinko game machine from being misused due to unauthorized modification. This effect can also be obtained. The address decoder 240 decodes address data A ₀ -A ₁₁ issued from the CPU 210 to generate a plurality of alternative selection signals S1 - S9. The decoding operation is performed by activating either the read control signal RD or the write control signal WD. These two control signals (RD/WD) are issued from the CPU 210.
Both signals RD/WD are ORed together by logic gate G1. This logical sum becomes a control signal for the address decoder 240. Parts S8 and S9 of the selection signals S1 to S9 output from the address decoder 240 are
20 and RAM 230 as a chip select signal. In addition, other selection signals S1 to S7
is used to control input/output circuits within I/O unit 250, which will be described later. In other words, a so-called memory-mapped I/O method is used here, in which input and output channels are arranged in address space. By adopting this memory-mapped I/O method, arbitrary input/output can be performed with just a simple process of accessing a specific address without the need for complex procedures such as opening and closing input/output channels. It is designed to perform input/output operations from the circuit. Note that the memory mapped I/O method had problems such as a part of the address space being occupied by the I/O area and becoming narrow, making it difficult to adopt it in general microcomputer systems. . However, in the control device 200 of this embodiment, as described above, the ROM 220 and the RAM
Since the storage capacity of each of the 230 is very small, the above problem does not have to be considered at all. The I/O unit 250 forms an interface (I/F) between the control device 200 and the pachinko gaming machine main body 300. This I/O unit 25
0 is provided with a large number of input/output circuits, as will be described later. The operation of each input/output circuit is individually controlled by the selection signals S1 to S7. The individual configurations of the input/output circuits will be described later, but for example, decoders, latch circuits, drivers, buffer gates, amplifiers, etc. are used. The clock generating means 280 generates a high precision clock pulse φk of, for example, 2 MHz by using a crystal resonator Xtal (4 MHz) as a frequency reference.
This clock pulse φk is applied to the clock terminal CK of the CPU 210. The reset signal generating means 290 generates a reset pulse φt of a constant period from the clock pulse φk. This reset pulse φt is applied to the CPU 21 mentioned above.
0 reset terminal R. This reset signal generating means 290 is constructed simply and on a small scale by a counter or the like. In this case, the reset pulse φt has a duty width, that is, a pulse width of the CPU 21.
It is made to have a length that can reliably reset 0. Further, the pulse generation interval, that is, the period, is set to be reliably longer than the processing time for the CPU 210 to execute a set of program instructions stored in the ROM. FIG. 11 shows the waveform of the reset pulse φt and the operating state of the CPU 210 in time response to each other. In FIG. 11, the reset pulse φt has a pulse width of 15 μs and a period of 3 ms. This 15 μs pulse width is sufficient time to reliably reset the CPU 210. Further, the period of 3 ms is sufficient time for the CPU 210 to execute all the instructions stored in the ROM 220. Further, as shown in FIG. 11 in time correspondence with the reset pulse φt, the CPU 210
Each time a series of program instructions written in the ROM 220 is completed, it is forcibly reset to a complete initial state.
As a result, even if the CPU 210 were to malfunction, such as running out of control or entering an infinite loop, the CPU 210 would be automatically restored to normal operating condition by being reset every 3 ms. As a result, the worst situations that were feared in CPU-based control systems, such as runaway or entering an infinite loop, can be reliably avoided. In other words, a kind of failsafe works here, ensuring that at least the normal operating state of the CPU 210 is maintained. In this way, the reliability necessary for a pachinko gaming machine is ensured. Furthermore, since the reset interval of the CPU 210 is a constant cycle, the number of resets can be
By storing the information in the RAM 230, a so-called soft timer function can be easily configured. Furthermore, since the reset interval is a relatively long time, for example 3 ms, even if the timer time is relatively long, for example from several seconds to several tens of seconds, it is possible to allocate a small storage area of 1 or 2 bytes. Therefore, it can be constructed very easily and concisely. For example, if the above reset interval is 3ms,
By allocating 1 byte of the RAM area to the timer area, the timer time from 3ms to 0.768 seconds can be obtained (3ms x 2 ⁸ = 768m
s=0.768 seconds). Allocating 2 more bytes,
You can get the timer time from 3ms to 196.608 seconds (3ms x 256 bytes x ²⁸ = 196608
ms=196.608 seconds). As a result, even if the RAM area is only 128 bytes, it is now possible to easily configure a large number of timer functions necessary to individually control various functions within the pachinko gaming machine main body 300. . Incidentally, the relatively long timer time of several seconds to several tens of seconds required to control the operation of the above-mentioned special variable prize winning device 5 (Figures 2, 6 to 9) can be obtained with just 2 bytes of RAM area. be able to. In FIG. 11, the halt state (standby state) is maintained from the time the program commands are executed until the next reset. This halt state is set by executing a halt instruction at the end of the program. In other words, the above program ends with a halt instruction. FIG. 12 shows an example of the configuration of the reset pulse generating means 290 (FIG. 10) that generates the reset pulse φt. As shown in the figure, the reset pulse generating means 290 includes a preliminary frequency dividing circuit 291, a counter 292, and a logic gate (AND gate) G2.
It can be easily configured by In the figure, Cin indicates a count input, and Cout indicates a count up output. With the configuration described above, reliability as a pachinko game machine can be ensured, and various functions necessary for controlling the operations of the pachinko game machine can be configured. Next, the configuration near the I/O unit 250 will be explained. As shown in FIG. 13, the I/O unit 250 includes a buffer gate 25 as an input/output circuit.
1. Latch circuits 252-256 are provided. The operations of these input/output circuits 251-256 are controlled by the aforementioned selection signals S1-S6.
In addition, each input/output circuit 251 to 256 is connected to a data bus
It is connected to the CPU 210 (FIG. 10) via an LD. The data exchanged between the pachinko machine main body 300 side and the control device 200 side is
It is now possible to put it on the data LD.
Furthermore, in addition to the input/output circuits 251 to 256, a scale generating means 257 is provided. The operation of this scale generating means 257 is also based on the above-mentioned selection signal S.
7. Among the input/output circuits 251 to 256, the buffer gate 251 constitutes an input circuit. This buffer gate 251 receives detection signals from various detection means SW1 to SW4 provided on the pachinko gaming machine main body 300 side, and transfers them to the data bus LD within the control device 200. In this case, the detection means include the aforementioned start switch SW1, stop switch SW2, continuation condition detection switch SW3,
There is a 10-count detector SW4 (Figures 3 and 7). Furthermore, among the input/output circuits 251 to 256,
Latch circuits 252-256 form output circuits. Additionally, latch circuits 252 and 254 therein each include a decoder. These decoders decode each display data of the light emitting diode type segmented displays LEDA to LEDE on the pachinko game machine main body 300 side. The display data is given from CPU 210 via data bus LD. The functions of each output circuit 252-256 are as follows. That is, the latch circuits 252 and 253 dynamically drive the segment type displays LEDA to LEDD of the variable display device 4 (FIGS. 2 to 5) described above. The display data is the data bus
Given from the CPU via LD. Note that each latch circuit 252, 253 is attached with a driver 262, 263, respectively, for increasing the driving force of its output. The latch circuit 254 is a segment type indicator LEDE.
Display drive. As described above, this display device LEDE displays the number of times the special right continues when a specific form of "jackpot" occurs. The display data is given from the CPU via the data bus LD. The latch circuit 255 individually drives the memory display lamps LED1 to LED4 made of light emitting diodes to turn on. Control data for the lighting is given from the CPU via the data bus LD. The memory display lamps LED1 to LED4 are used, as described above, to display the number of reserved batted balls that have won the specific prize openings 7 and 8 (FIGS. 2 and 3). The latch circuit 256 individually drives the drive source and display means on the pachinko gaming machine main body 300 side via the driver 266. The driving source in this case is the electromagnetic solenoid 66 (FIG. 9) that drives the special variable winning device 5 mentioned above to open. In this case, the display means is the continuation condition fulfillment display section 29 (the third,
Figure 9). Further, the scale generating means 257 generates a sound source having a predetermined scale. The generated sound source is the amplifier 26
7, and is applied to the speaker SP for generating sound effects on the pachinko gaming machine main body 300 side. The scale of this sound source is set by data given from the CPU via the data bus LD. FIG. 14 shows the configuration of the scale generating means 257. As shown in the figure, the scale generating means 257
is a latch circuit 256 that holds scale setting data.
a and a presettable counter 256b. The latch circuit 256a holds scale setting data given from the CPU via the data bus LD. This latch circuit 256a is connected to the selection signal S
The data on the data bus DL when 7 becomes valid is read and held. The held data is preset to the count contents of the presettable counter 257b. The presettable counter 256b is a type of down counter, and is decremented by one by the clock pulse φk. The initial count contents are preset by the latch circuit 256a. Each time the preset count is decremented to "0", the data held in the latch circuit 256a is newly preset. Here, the presettable counter 256b
The output state of the carry terminal (count output terminal) Crry changes from its logic level H (high level) to L (low level) or from L (low level) every time the count content is decremented to "0". H (high level)
transitions alternately. As a result, H (high level) and L (low level) are output from the carry terminal Crry.
A signal is obtained that alternately transitions between . and,
This signal is now used as the above-mentioned sound source. This sound source is amplified by an amplifier 267 and given to a speaker SP for generating sound effects on the pachinko gaming machine main body 300 side. At this time, the scale of the sound source is determined by the preset value. Furthermore, if the preset value is small, the period of the above-mentioned transition becomes longer and the pitch becomes lower. Furthermore, if the preset value is small, the above-mentioned transition period becomes short and the pitch becomes high. The preset value is then set to the CPU 21 above.
It can be arbitrarily set variably by 0 (FIG. 10). Thereby, the control device 200 can arbitrarily generate a sound effect such as a fanfare sound in the pachinko game machine main body 300. Note that the presettable counter 257b may be an up counter. Next, the software configuration of the above-mentioned control device 200 will be explained together with its operation. FIG. 15 shows the control device 200 (10th,
Fig. 11) shows the entire processing flowchart. FIG. 16 shows an enlarged part of the processing flowchart. First, the following Table 1 shows the CPU 2 of the control device 200.
10 (FIG. 10) shows the allocation contents of the address space section accessed by the memory map. Note that the address is expressed in hexadecimal numbers from O to F. In Table 1 below, the range of addresses accessed by the CPU 210 is the 64k byte address space (addresses 0000 to FFFF) of the CPU (Z80) 210.
The address is between 0000 and 4000. Of these, 2k bytes from addresses 0000 to 07FF are
Allocated to ROM area. Also, from 0800
128 bytes up to address 087F are allocated to the RAM area. And 1000, 1800, 2000,
An I/O area of 1 byte each is allocated to 2800, 3000, 3800, and 4000. In this case, the gaps between each I/O area are not used. Therefore,
The size of the address space that the CPU 210 actually accesses is only about 2 kbytes.

[Table] Next, the operation of the control device 200 described above will be explained with reference to FIG. 15 and Tables 1 and 2 above. In FIG. 15, the CPU 2 of the control device 200
10 is the reset pulse φt (10th, 1st
1 and 12), the device is forcibly reset by hardware. This reset causes the CPU to start up from a completely initial state. When the CPU is started from the initial state after being reset, it first loads ROM2.
Access is started from 20, and the program instructions stored there are sequentially read and executed. As a result, a series of processes shown in FIG. 15 are started. When execution of a program instruction is started, a stack pointer is first set (R1). Next, it is checked whether start data indicating the beginning of the backup area (addresses 0838 to 0843) and end data indicating the end thereof have been set (R2-R3-R14-R15). Here, in the first operation after the control device 200 is cold started (started by applying current), initial settings of the program are performed (R1
7). In this initial setting, all variable data such as output data and count data stored in the I/O area are initialized. Thereafter, the start data and end data are set (written) (R11). The start data and end data should be set to values that can reliably reflect memory errors in the RAM 230, such as A5 (in binary numbers).
10100101) is used. Furthermore, after transferring the initialized data to the backup area, a halt instruction is executed to transfer the processing to the CPU.
Stop it by itself (R12-R13). Then, it is reset by the next reset pulse φt. The operating state of the control device 200 is initialized as described above. After this initialization of the control device 200 is performed,
Each time the reset pulse φt is issued, the CPU
Main routines R1 to R13 are executed sequentially. In this main routine, as shown in FIG. 15, the following processing is executed. R1: Set stack pointer. R2, 3: Check the end data of the backup area. R4: Performs input processing to detect the rise of the start switch SW1, stop switch SW2, continuation condition detection switch SW3, and 10 count detector SW4. This is done by referring to the previous detection signal and each current state. The state of the previous detection signal is stored in the buffer area. This memory state is constantly updated. R5: Memory processing of the number of activations of the start switch SW1. The variable display device 4 (FIGS. 2 to 7) described above is
It is activated by the specific winning ball detection operation of the start switch SW1. In this processing retin,
The number of winning balls, that is, the number of times the start switch SW1 is operated, is stored until the variable display operation of the activated variable display device 4 is stopped. If the number of operations is stored, that is, if the stored value is 1 or more, the variable display device 4 is activated again after the variable display operation is completed. When the variable display device 4 is restarted, the stored value is incremented by one. That is, in this processing routine, a process is performed to preserve the right to start the game resulting from winning in the early specific winning openings 7 and 8 (FIGS. 2 and 3). R6: Performs 10 count detector SW4 illegality check processing. It is logically determined whether the function of the 10-count detector SW4 is impaired due to a disconnection or short circuit of its connection or wiring, based on the input state from the detector SW4. R7: Update the timer values of various timers stored in the RAM area. R8: Set the operation parameters (scale data) of the scale generation means 257. In this processing routine, processing is performed to output scale setting data for generating sound effects such as fanfare. R9: Performs control processing for various display means, electromagnetic solenoids, etc. In this processing routine, the above-mentioned jackpot display lighting means 27 and continuation condition fulfillment display section 29
(Figures 3 and 8) and the electromagnetic solenoid in the special variable winning device 5 mentioned above.
Drive control of SOL (Figure 9) is performed. R10: Performs various determination and control processes related to winning. Here, the operation control of the first variable display device 4,
And a series of processes related to the occurrence of specific aspects such as "big hit" and "medium hit" are performed. The detailed contents of this routine R10 are shown in FIG. R11: Setting (writing) processing of start data and end data indicating the earlier and later applications of the backup area described above is performed. R12: Performs processing to transfer variable data such as output data to the backup area. After the main routines R1 to R12 described above have been executed, a halt instruction is executed in the final processing routine R13. This causes it to enter a standby state in which it stops continuing the process. Furthermore, when an error occurs in the end data due to some abnormality during the execution of the main routines R1 to R12 described above, routines R2-R3 for checking the end data to routines R14-R15 for checking the start routine are executed.
Branching is now taking place. and,
If an error also occurs in the start data in the branched routine R14-R15, the routine R17 for initializing the program is re-executed.
The state of the control device 200 is returned to the state immediately after the cold start. In this way,
Fail-safe is designed to guide the control state of the control device 200 in a safe direction when an abnormality occurs. On the other hand, if the error occurs only in the end data and there is no abnormality in the start data, routine R16 is executed and the backed up data is transferred to the main work area 0800~ of the CPU.
It will now be retransferred to 080A. This results in
If the degree of error is minor, it is possible to automatically return to normal operation while preserving the intermediate state of control. FIG. 16 shows a detailed flowchart of the above award processing routine R10. As shown in the figure, this winning processing routine R1
0 consists of subroutines R101 to R122, and processes related to a specific prize winning, that is, a series of controls related to the operation control of the first variable display device 4 and the generation of the first specific mode, are executed by process numbers 1 to 8. I'm starting to get used to it. In other words, the above-mentioned start switch SW1, stop switch SW2, continuation condition detection switch SW3,
A processing number is set based on each detection state of the 10-count detector SW4. By selectively executing a subroutine prepared in accordance with the established processing number, it is possible to cause the above-mentioned pachinko game machine to perform a specific winning-related processing device. . Here, the processing number is set to any one from No. 0 to No. 8. In this case, in process No. 0, only a check is performed as to whether or not the operation start conditions No. 1 to No. 8 are satisfied, and no process related to a specific winning is performed. Processing related to specific winnings
This is performed when any of the processing numbers from No. 1 to No. 8 is set. The following subroutines R111 to R correspond to each processing number from No. 1 to No. 8.
118 are available. That is, when the process number is set to No. 1, routine R111 is executed. In this routine R111, processing for starting the variable display device 4 is performed based on the detection of the start switch SW1. After this process is executed, the next process number
No.2 is set. When the process number is set to No. 2, routine R112 is executed. In this routine R112, the operation of the variable display device 4 is stopped in stages based on the detection of the stop switch SW2. At this time, a process is performed in which a randomly set time is partially inserted into the time until the display operation stops. This randomizes the display contents after the operation is stopped. After this process is executed, the next process number No. 3 is set. When the process number is set to No. 3, routine R113 is executed. In this routine R113, processing is performed to determine whether or not a specific mode has occurred based on the result of stopping the variable display device 4. The determination is made based on the stopped display content.
If a specific form of "jackpot" is determined, processing number No. 5 is set. Further, when a specific mode of "mid-hit" is determined, processing number No. 6 is set. In other cases of loss, processing number No. 0 is set. When the process number is set to No. 4, routine R114 is executed. In this routine R114, control processing is performed when a specific aspect of a "big win" occurs, for example, control to open the special variable prize winning device 5. In addition, timer processing is also performed, thereby limiting the opening driving time to a relatively long predetermined time (about 30 seconds). moreover,
Blinking drive processing for related display means is also performed. After execution of this routine R114, process number No. 7 is set in order to determine whether or not to continue. When the process number is set to No. 5, routine R115 is set. In this routine R115, the operating parameters of the scale generating means 257 are set to perform a process of generating a fanfare sound accompanying the occurrence of a specific form of a "jackpot". After execution of this routine R115, process number No. 4 is set. When the process number is set to No. 6, routine R116 is executed. In this routine R116, control processing is performed when a specific mode of "medium hit" occurs, for example, control to open the special variable prize winning device 5. In addition, timer processing is also performed, thereby limiting the opening drive time to within a relatively long predetermined time (about 6 seconds). moreover,
Blinking drive processing for related display means is also performed. Processing number No. 0 is set after the predetermined time has elapsed. When set to processing number No. 7, routine R
117 is executed. In this routine R117, the special variable winning device 5 is re-driven based on the detection of the continuation condition detection switch SW3. This process is executed when a specific form of "jackpot" occurs. After execution of this routine R117, the next process number No. 8 is set. When the process number is set to No. 8, routine R118 is executed. This routine R118 performs processing after the "big win" state ends. When the "jackpot" operation is completed, a delay time of about 3 seconds is set, and if it is confirmed that the condition of the "jackpot" state is met during that time, the processing number is set to No. 7. If the continuation condition is not satisfied, process number No. 0 is set. Here, the series of winning-related processes described above are started by setting process number No. 1. This processing number No. 1 is set when the number of times the start switch SW1 is turned on is stored (routines R109 and R120). As above, while updating the process number,
Operation control of the variable display device 4 and winning-related processing in response to the occurrence of a specific mode are performed. FIG. 17 shows the configuration of the variable display control section configured in the control device 200 described above. The control section shown in the figure is a section that controls the variable display operation and the starting and stopping operations of the variable display device described above. This control section is configured in terms of software by the above-mentioned microcomputer. The control section shown in FIG. 17 first includes display data updating means 02 for updating the display contents of the variable display device 4. The control section shown in FIG. This display data updating means 02 is provided with a specific value adding means 01 that repeatedly adds a specific value every 12 ms. The display content of the variable display device 4 is determined every 12 ms based on the addition result of a certain number of digits (lower three digits) sequentially obtained from the adding means 01 every 12 ms. That is, the display contents of the variable display device 4 are updated every 12 ms, and the updated data is provided from the adding means 01. Furthermore, in the embodiment, the specific addition means 01 is configured to repeatedly add eigenvalues selected from prime numbers. Furthermore, specifically, it is configured to repeatedly add 137, which is a three-digit prime number. When this three-digit prime number 137 is repeatedly added by the adding means 01 and only the lower three digits are taken out as effective values, the following numerical values are sequentially obtained every 12 ms. First, if we repeatedly add the specific value 137 and arrange the addition results for each addition in the order of their occurrence, we get 137, 274, 411, 548, 685, 822, 959, 1026,
1233, ..., 13700, ..., 27400, ...,
You can get a numerical string with discrete values such as 137000, 137137, 137274, etc. Here, the lower 3 of each number that composes the number sequence
If you take out only the digits, 137 , 274, 411, 548, 685,
822, 959, 026, 233, ..., 700, ..., 400, ...
..., 000, 137 , 274, ..., etc., it looks as if the number strings made up of three mathematical combinations are arranged randomly, and the number strings with the same combination appear periodically. If a different value other than 137 is taken as the above specific value, a different numerical sequence than the above will be obtained. Furthermore, if we use a 3-digit prime number such as 137 as the specific value above, the same combination of numbers will be exactly
Obtained once in 1000. For example, if we focus on the number 137, this number "137" appears exactly once every 1000. The same applies when focusing on other numerical values. During those 1000 times, the same number appears only once. In other words, different combinations of numbers are obtained 999 times in a row. Therefore, as described above, the specific addition means 01 for repeatedly adding a specific value is provided, and this addition means 01
By configuring the display content of the variable display device 4 to be determined based on the addition result of a certain number (lower three digits) sequentially obtained from , the display content of the variable display device 4 can be updated as if at random. At the same time, for example, it becomes possible to average specific combinations of numbers that result in a specific aspect such as a "jackpot" at regular intervals. As a result, even with a relatively simple and concise configuration, while ensuring randomness in the display update operation of the variable display device 4, it is possible to average the probability that the aforementioned specific mode actually appears within a relatively short finite gaming period. This makes it possible to provide fairer services to players. Furthermore, by selecting the specific value described above, it is also possible to set the probability that the specific mode will appear within a predetermined range. For example, out of the 100 combinations of numbers mentioned above, suppose "111", "333", "555", "777", "999"
”
Suppose that a specific number string is determined in a specific manner called a "jackpot." Then, these specific number strings are
They are almost evenly distributed within the above numerical sequence as follows. In other words, in the numerical sequence mentioned above, "111"
and "333", between "333" and "555", between "555" and "777", and between "777" and "999".
There are 206 non-specific digit strings in each. Also,
There are 176 non-specific numbers between "999" and "111". In this way, specific numeric strings are never next to each other or close to each other, nor are they extremely far apart. Every particular string of numbers is arranged at approximately uniform intervals. As a result, if the addition operation by the addition means 01 is performed slightly more than 1000 times or an integer multiple thereof, each time a slightly more than 1000 addition is completed, a different number string will appear each time, and approximately The above specific number string will appear at a certain rate. This makes it possible to further equalize the frequency with which the specific aspect of the above-mentioned "jackpot" occurs. Note that the specific value does not necessarily have to be "137", and may be another prime number or a numerical value other than a prime number (for example, a random number generated by a random number generation circuit) as necessary. Furthermore, the addition means 01 referred to here includes one that performs subtraction. Even if subtraction is performed instead of addition, the above-mentioned effect can be obtained in the same way. Here, in the example, as shown in FIG.
In addition to the above configuration, the display data updating means 02
An unspecified timer TM1 is provided that inserts an unspecified time period from 12 ms to 120 ms between the start and stop of the update operation. Also, the time period from when the updating operation of the display data updating means 02 is started to when it is stopped is the time (12000 ms) for the addition results of the specific addition means 01 to complete one round, that is, equivalent to one period of the numerical sequence mentioned above. In order to insert a time slightly longer than the time (1000 x 12ms = 12000ms), a specific timer TM having a timing time of 12000ms, that is, 12 seconds, is used together with the unspecified timer TM2.
1 is provided. As a result, each time the variable display device 4 stops its updating operation, it stops at a position slightly beyond the previous stop position and displays the combination of numbers located at this stop position. In this case, only a portion slightly exceeding the previous stop position is randomly determined by the unspecified timer TM2. As a result, as mentioned above,
The combinations of numbers in the numerical value string appear almost uniformly and are stopped and displayed without partial bias. Furthermore, regarding the unspecified timer TM2,
An unspecified time data storage area 08, unspecified data generation means 06, and unspecified time data selection means 07 are provided. The unspecified time data storage area 08 stores multiple types of time data (1×12 ms to 10×12 ms) in the form of one-digit integer values from 0 to 9, randomly distributed. This storage area 08 is ROM2
Allocated within 20. The unspecified data generating means 06 generates unspecified data having random values. The unspecified time data selection means 07 selects the time data in the storage area 08 based on the unspecified data given from the unspecified data generation means 06, and applies the selected time data to the unspecified time timer TM2. Set as a timer value. This makes it possible to highly randomize the number of times of addition by the adding means 01, and to provide even better randomness to the display contents of the variable display device 4. On the other hand, the display data updating means 02 is provided with a plurality of data holding means 02A, 02B, 02C as well as the specific value adding means 01. These plural data holding means 02A, 02B, 02
C is provided corresponding to the plurality of segment type displays LEDA to LEDC of the variable display device 4.
The first data holding means 02A holds the numerical data of the third lower digit displayed by the corresponding first display device LEDA. The second data holding means 02B has a corresponding second display LEDB.
Holds the numerical data of the second lowest digit displayed.
Similarly, the third data holding means 02C holds the numerical data of the first lower digit displayed by the corresponding third display device LEDC. Along with this,
The first holding means 02A includes the adding means 01.
Among the three-digit effective addition output data D0, D1, D2, the third digit numerical data D2 is stored in the second holding means 02B, and the second digit numerical data D1 is stored in the second holding means 02B.
The first digit numerical data D0 is input to the third holding means 02C. As a result, each display content of the variable devices LEDA to LEDC is given by the addition result of the addition means 01, and is updated at fixed time intervals (12ms) in synchronization with the addition cycle. . Furthermore, the display updating means 02 includes a timer.
TM3 and TM4 are provided. this timer
TM3 and TM4 are data holding means 02A and 0
The stop timing of the update operations of 2B and 02C is sequentially delayed by a certain period of time (120 ms). As a result, the display update operation of each display unit LEDA to LEDC is
As if the rotation had stopped, it stops one after another starting from the end. FIG. 18 shows the operations of each part of the variable display device 4 from when the display updating operation is started until it is stopped, in a time-corresponding manner. In FIG. 17 and FIG. 18, the specific time timer TM1 is activated based on the ON setting of the start switch SW1 by the specific winning ball or the memory of the number of ON settings. (12000ms = 12 seconds). This specific time timer TM1 finishes counting the specific time (12000ms) or the stop switch SW2 is turned on (ON) by manual operation.
Once set, the unspecified time timer TM2 is activated. The unspecified time timer TM2 measures an unspecified time (12 ms to 120 ms) selected by the unspecified time data selection means 07. When the time measurement ends, that is, when the unspecified time set in the timer TM2 has elapsed, an operation is started to sequentially stop updating of the display contents of the segment type displays LEDA to LEDC. The operation of stopping update of each display content in the segment type display devices LEDA to LEDD is performed in the following order. First, when the unspecified time timer TM2 finishes counting, updating of the display contents of the first display device LEDA is stopped. At the same time, the first stop interval setting timer TM3 is activated. This timer TM3 measures a certain period of time (120ms). This fixed time (120 ms) corresponds to exactly 10 times the addition period (120 ms) of the adding means 01. When the time measurement is finished, that is, the display LEDA
A certain period of time (120
ms), the update of the display contents of the second display LEDB is stopped. At the same time, the second stop interval setting timer TM4 is activated.
This timer TM4 also measures a certain period of time (120ms). This fixed time (120 ms) also corresponds to exactly 10 times the addition period 120 of the addition means 01. Then, the 20th addition cycle (12 ms x 20
times = 240ms), the third LEDC
Display contents update will be stopped. As described above, updating of the display contents on each of the segment type displays LEDA to LEDD of the variable display device 4 is stopped sequentially at fixed time intervals (120 ms). At this time, before the stop operation is performed, the unspecified timer TM2 is activated for an unspecified time (12ms to 120m).
s) is inserted. As a result, the variable display device 4 started by the start switch SW1
The timing at which the variable display operation stops can be changed randomly, regardless of, for example, the operation timing of the stop switch SW2. Along with this, the respective stop display contents on the segment type indicators LEDA to LEDD of the variable display device 4 are randomized. This randomized state can be maintained even when the display update period and update stop interval of the variable display device 4 are kept constant.
Or if all other actions are regularized,
will definitely appear. In this way, even with a simple and concise configuration in which unspecified components are provided at only one location, it is possible to reliably provide randomness to the operation of the variable display device 4. The following Table 3 shows the above unspecified time data storage area 0.
An example of the configuration of No. 8 is shown below. As shown in Table 3 below, in the unspecified time data storage area 08, data is expressed as an integer from 0 to 9.
10 types of time data are stored. These 10 types of time data are randomly distributed and stored in a much larger number (128 pieces) than the types of time.

【table】

[Table] In Table 3, the composition ratio of each time data, that is, the frequency of occurrence of unspecified time is as shown in Table 4 below. Furthermore, Table 5 shows the correspondence between each unspecified time data from 0 to 9 and real time.

【table】

[Table] FIG. 19 shows an example of the configuration of the unspecified data generating means 06. As shown in the figure, the unspecified data generating means 06 is composed of a reset number counting means 061, a refresh counter 062 in the microcomputer (Z80), and a logic operation means 063. The reset number counting means 061 is
Count the number of times the CPU is reset. Contents obtained by extracting only the counted value, especially its lower digit (corresponding to the last digit 0 to 9 of the decimal number) C61
depends on the time when the microcomputer was first started up when the power was turned on, and the accumulation of extremely small frequency variations in the clock pulses.
Takes an unspecified value. In other words, it's randomized. Further, the refresh counter 062 is for refreshing the dynamic RAM, operates automatically within the microcomputer, and cannot be operated from the outside. Therefore, the content C62 is also the same as the reset number counting means 06.
Like 1, it is randomized. Furthermore, the logical operation means 063 performs logical operation processing on the two types of contents C61 and C62. The logical operation in this case is an exclusive OR. The calculation result of this logical calculation means 063 is used as the above-mentioned unspecified data. In this case, only the lower digit values (numerals from 0 to 9 in decimal notation) are extracted from the calculation result and used as the unspecified data. In addition, each of the above two types of contents C61 and C62 has sufficient randomness even when used alone.
Therefore, the content C61 or C62 may be used as is as the unspecified data. However, by the logical operation means 063,
By performing logical operations on the two types of contents C61 and C62, unspecified time data with even higher randomness can be obtained. In the above embodiment, all display contents of the variable display device are determined by the addition results of a certain number of digits sequentially obtained from the addition means that repeatedly adds a specific value. The content may be given from a counter or the like provided separately from the addition means, and the display content at the time of stop may be given from the addition means. In addition, in this embodiment, the gaming machine is described as a pachinko gaming machine, but it is not limited to a pachinko gaming machine as long as it uses a variable display device, and can be used as a slot gaming machine, an arrangement ball machine, etc. It may be a gaming machine having a display device. [Effects] As clarified above in the description of the embodiments, the gaming machine according to the present invention adds or subtracts a given value that repeatedly adds a specific value to the display data updating means of the variable display device. By providing a calculation means and determining the display contents of the variable display device at least when the variable display device is stopped based on the calculation results sequentially obtained from the calculation means, the variable display can be performed with a relatively simple and concise configuration. While ensuring randomness in the display update operation of the device, it is possible to average the probability that a specific aspect, such as a "jackpot", will actually appear within a relatively short finite playing period, thereby improving services for players. This has the effect of making it fairer.
