Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine, and more particularly to a game machine effectively applied to a game machine provided with a variable display device for forming a game state.

[0002]

2. Description of the Related Art For example, in the field of pachinko gaming machines, an electric prize winning device called a so-called accessory (yakumono) is provided for the purpose of improving services to game players and expanding the number of customers who can enjoy games. Things are being developed. With the addition of the accessory, the content of the game is diversified, and thereby the healthy enjoyment of the player can be increased.

In this kind of pachinko gaming machine with accessories,
A variable display device and a winning device that operates on condition that the display content of the variable display device is stopped in a specific mode are provided.

The variable display device forms a kind of game device in the game area of the pachinko gaming machine. This variable display device is activated, for example, when a hit ball is won in a specific winning area arranged in the game area, and operates so as to constantly change the display content. The variable display operation for changing the display is stopped by a manual stop operation or a lapse of a specific time by a timer. When the variable display operation is stopped, the display contents after that are stopped until the next start. Here, when the display content is stopped in a predetermined specific mode, that is, when the specific mode occurs, a so-called “big hit” or “medium hit” state occurs. When the "big hit" or "middle hit" state occurs, the winning device operates to temporarily give the player a special profit that dramatically increases the winning probability. As a result, everyone is given equal opportunity to obtain a large amount of winning profit, and the service to the players is fair and fair. Along with this, the contents of the game are diversified, and the healthy enjoyment of the player can be increased.

[0005]

However, in order to make full use of the advantages of the pachinko gaming machine with an accessory as described above, the stop display contents of the variable display device must be surely randomized. . Otherwise, the fun of the game will decline and, for example,
Depending on the timing of the manual stop operation, it is possible to intentionally increase the frequency of occurrence of the above-described specific aspect, which may cause an adverse effect.

However, if the display update operation of the variable display device is simply randomized by the ordinary statistical means, the following problems may occur.
It was made clear by the present inventor.

That is, if the display updating operation is simply randomized by a normal statistical means, the probability of occurrence of a particular mode such as "big hit" is macroscopic over a very long almost infinite sample period. According to statistics, statistically, it may be possible to get a certain rate. However, the probability that the specific aspect actually occurs within a relatively short finite sample period during which the player is playing the game does not always follow the theory, but rather varies greatly, for example, " Jackpot "
It has been found that a state occurs in which the specific mode of No. occurs continuously or the specific mode does not occur at all. For this reason, it has been very difficult to provide fair service to the players.

The present invention solves the above-mentioned contradictory problems all at once, and its purpose is to achieve a display update operation of the variable display device with a very simple and simple structure. While eliminating the periodicity and ensuring randomness, it is possible to average the probability that the above-mentioned specific aspect actually appears in a relatively short finite game period, thereby fairing the service to the player. It is to provide a game machine that can be measured.

The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

[0010]

The typical ones of the inventions disclosed in the present application will be outlined below.

That is, according to the present invention, as a means for achieving the above object, as shown in FIG. 1 in which the main configuration is made to correspond, a variable display device 4 having a plurality of display portions and forming a game state, Display data updating means 02 for updating data corresponding to the display content of the variable display device is provided, and when the display content of the variable display device 4 is stopped in a specific mode, a special game state is generated to give a special profit. In the gaming machine configured to, the display data updating means 0
2, the calculation means 01 for adding or subtracting a predetermined value to the previous calculated value and the data corresponding to the display contents when the variable display device 4 is stopped correspond to each of the plurality of display portions of the variable display device. Display data holding means 02
A, 02B, 02C are provided, and data corresponding to at least display contents of the variable display device 4 when the variable display device 4 is stopped is uniquely determined based on the values sequentially obtained from the calculation means and held in the display data holding means. It was done like this.

[0012]

According to the present invention, arithmetic means for adding or subtracting a given value is provided, and the display contents at least when the variable display device is stopped is uniquely determined based on the arithmetic results sequentially obtained from the arithmetic means. By configuring so as to determine, it is possible to update the display contents of the variable display device as if at random, and for example, a specific combination of numbers that causes a specific aspect such as "big hit" is averaged at regular intervals. Then you can make it appear.

Further, by providing the display data holding means for holding the display contents when the variable display device is stopped, the display contents of the variable display device are sequentially stopped with a time lag toward the determined display contents when the variable display device is stopped. You can do it.

Further, a supply tray 102 for holding a hit ball supplied to a hit ball launching device is attached to an opening / closing panel 101 attached to the holding frame 100. Further, below the receiving tray 103, a receiving tray 103 for storing prize balls overflowing from the supply tray 102 is provided.

A pressing operation type stop switch SW2 is provided on a side portion (left side in the figure) of the holding frame 100. 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 opening to the specific winning opening 7 or 8.

In the pachinko gaming machine configured as described above, when a hit ball hit into the game area 1a by the hitting ball launching device 2 wins in any prize area, a predetermined number (usually 10 to 15 pieces) is thereby generated. ) Prize balls are paid out. Further, the winning prize ball is a specific winning opening 7 or 8
, The variable display device 4 is activated. And the segment type display LED of the variable display device 4
The four numbers displayed by A to LEDD can be changed respectively. Here, when the player pushes the stop switch SW2 or when a certain amount of time elapses, the operation of the variable display is stopped. At this time, when the combination of the displayed numbers after the stop comes to a predetermined execution result, the specific mode is generated.

When a specific mode occurs, the special variation winning device 5 is converted from the closed state to the open state, so that the winning area by the above-described special variation winning port 80 is temporarily opened and provided in the game area 1a. become. As a result, the probability of winning the prize is shifted from zero to a very high state. As a result, the player is provided with a special opportunity to generate a large number of prize balls in a relatively short time and obtain a large number of prize balls. In this case, there are two types of states caused by the specific mode, "big hit" and "medium hit" depending on the combination of the displayed numbers.

The state of "big hit" occurs when a specific mode occurs in which all four display numbers are aligned with one of the predetermined specific numbers. The “middle hit” state occurs when a specific mode in which any three of the three display numbers are aligned with one of the predetermined specific numbers is generated. In other words, when there are four alignments, a "big hit" is given, and when there are three alignments, a "middle hit" is given.

When a specific mode of "big hit" occurs, the special variation winning device 5 is operated for a relatively long predetermined time (about 30 minutes).
Seconds) during the open state. Thereby, the probability of winning is dramatically increased. Further, when a hit ball wins in the continuous winning opening 81 set in the special variable winning opening 80 while the special variable winning device 5 is kept open, the special variable winning device 5 temporarily returns to the closed state. After that, it is set to the open state again. That is, the special variable winning device 5
The time for which the open state is maintained is substantially extended. Thereby, an extremely large number of winning opportunities are given to the player.

When the "middle hit" specific mode occurs, the special variation winning device 5 is set to the open state for a relatively short predetermined time (about 6 seconds). This gives the player the opportunity to get a much larger number of prize balls than in the normal case, but not as much as a "big hit".

Here, the combination of numbers displayed on the variable display device 4 can be changed randomly. Therefore, the special occasion according to the above-mentioned specific embodiment is
The game can be given almost equally regardless of individual differences such as the skill level of the game. As a result, even a beginner can enjoy a chance opportunity according to the specific mode.

However, if the profit given to the player by the above-mentioned special occasion is too large, then there is a fear that the unnecessary euphoria will be fueled. Therefore, in order to prevent the ambition from being agitated, in the control operation related to the occurrence of the above-described specific mode, the following control operation is performed together.

That is, when the "big hit" state occurs, when the number of winning balls to the special variation winning device 5 reaches a certain limit number (10), the special variation winning device 5 is predetermined. It is possible to immediately forcefully return to the closed state without waiting for the lapse of time (about 30 seconds). Further, the number of continuous setting of the open state due to the winning in the continuous winning opening 81 is also limited to a certain number (ten times) or less.

As a result, it does not spoil the player's sound interest and does not fuel unnecessary euphoria.

On the other hand, although illustration is omitted, when the "big hit" and "medium hit" specific modes occur, in addition to the control operation described above, depending on the type of the specific mode,
For example, sound effect control such as fanfare is also performed to control the effect display by sound. The sound effect such as a fanfare, which will be described later in detail, is generated electronically and emitted from a speaker (not shown) incorporated in the gaming machine. With such an effect display, the player can experience fun other than obtaining the prize ball.

When the four numbers appearing in the EDC and LEDD are in a specific combination (diagram), a specific mode that gives a special benefit is generated. In this embodiment, for example,
All numbers of the variable display member 47 are "1", "3",
When the numbers are aligned to "5", "7" or "9", that is, when the numbers are aligned (zolome), a first specific mode called "big hit" is set. The variable display members 47,
Any three out of the four numbers of 48 are "1", "3",
When the "5", "7", or "9" is reached (Zorome), a second specific mode called "medium hit" is set. No specific mode occurs for any other roll.

On the other hand, the jackpot display illumination means 27 on both sides of the variable display device 4 are driven to blink while the display of the variable display members 47 and 48 is changing. Further, when a state of "big hit" or "medium hit" occurs when the display change of the display members 47 and 48 is stopped, the blinking speed is controlled to increase.

Further, the memory display lamps LED1 to LED4 under the variable display device 4 are controlled so as to be turned on as many times as the number of the variable display portions held.

The winning ball guiding gutter 54a is formed at a position corresponding to the pair of winning devices 53 on the front surface of the mounting board 50. Then, it acts so as to guide the hit ball that entered the winning opening 53a to the back of the game board.

Furthermore, a prize winning device 53 is detachably attached to each of the left and right sides of the mounting board 50. As shown in FIGS. 6 and 7, each winning device 53 is provided with a rotating member 70 and an illuminating means 53b. The winning device 53 is provided with a winning opening 53a that opens upward at the upper end thereof. The winning opening 53a is a general winning opening as described above.

Here, the special variation prize winning opening 51 is opened / closed in response to a specific mode 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-back direction. When the special variable winning opening 51 is opened, as shown in FIG. 7, a special variable winning opening 80 having a much wider width than the general winning opening is temporarily opened. In this special variation winning opening 80, along with a normal winning opening 82 that provides only a normal winning profit that a predetermined number of prize balls are paid out, a continuous winning that provides the right to continue or extend the above-described specific mode. A mouth 81 is formed.

Further, an operating piece 51a is formed on one side (the right side in FIG. 7) of the above-mentioned special variation winning port 51.
The end portion of the operating piece 51a is projected from the elongated hole 52a formed in the back plate 52 to the back surface side of the back plate 52. And it is designed to be engaged with an electromagnetic solenoid described later via the transmission member 65. As a result, the special variable winning port 51 is driven to open and close via the operating piece 51a.

FIG. 6 shows a state in which the special variation winning port 51 is raised rearward to close the special variation winning port. FIG. 7 shows a state in which the special variable winning opening 51 is opened by the door-shaped special variable winning opening 51 falling forward.

On the other hand, on the back side of the mounting board 50, a pair of winning ball guiding members 56a, 56b having a substantially L shape are formed along the lower edge of the window 50b. The tip ends of the pair of winning ball guiding members 56a and 56b are opposed to each other with an interval of about one sphere. Further, an engagement recess 57a is formed at the tip of one of the winning ball guiding members 56a. At the same time, an engaging portion 57b is formed below the base end side of the other winning ball guiding member 56b. By the engagement portion 57b and the engagement recess 57a,
A detector SW4 for detecting and counting the number of winning balls to the special fluctuation winning opening 80 is mounted and held. This detector SW4 is what is called a 10-count detector, and here, a non-contact type proximity switch is used. This 10-count detector SW4
The detection unit 31a at the tip is connected to the guiding members 56a and 5
6b is mounted so as to reach within the interval between both ends. As a result, the 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 rearranging room 58 is formed in the special variation winning port 80. In this rearranging room 58, the upper, lower, left and right sides thereof are the surrounding frame 54.
(FIG. 8), the lower side of the winning ball guiding member 56a,

After passing through the winning ball, the winning ball is the arc-shaped direction regulating portion 5 shown in FIG.
0d leads to one side (right side in FIG. 8). This arc-shaped direction restricting portion 50d is provided as shown in FIG.
As shown in the figure, the lower surface of the mounting substrate 50 is formed integrally with the lower surface.

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. This guide plate 52
By c, the upper part of the sorting room 58 is divided and separated into the above-mentioned continuous winning opening 81 and the ordinary 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. The sensing piece 60 is suspended from the support protrusion 52d via a pin 59 in a swingable state. The sensing piece 60 is urged so as to enter and exit the continuous winning opening 81 shown in FIG. As a result, the hit ball that has won the continuous winning opening 81 (FIG. 7) is guided by the pair of guide plates 52c and protrudes forward from the rear opening window 52b as shown in FIG. 7 and FIG. After the sensing piece 60 is rotated backward, the sensing piece 60 flows downward to the detecting portion 31a of the 10-count detector SW4, where it is detected and counted one by one together with the hit ball that has won the ordinary winning opening 82. It has become so.

As shown in FIG. 8, the sensing piece 60 is weakly elastically biased so as to project forward from the opening window 52b by the elasticity of the actuator 32a of the continuation condition detecting switch SW3 including a micro switch. Has become. The continuation condition detection switch SW3 is for detecting a hit ball which has won the continuation winning opening 81,
It is attached to the back plate 52 via an L-shaped attachment member 61.

The continuation condition detecting switch SW3 is positioned so that the actuator 32a comes into contact with the pressing portion 60a bulged on the back surface of the sensing piece 60. Sensing piece 6
0, a pin hole 60b through which the pin 59 is inserted.
And a stopper portion 60c protruding rearward to restrict the rotation range of the sensing piece 60. The support pin 59 of the sensing piece 60 engaged with the support protrusion 52d is
The rotation restricting portion 62a formed integrally with the pressing member 62 is fixed to the support projection 52d to prevent the rotation restricting portion 62a from coming off. Further, a slit portion 62d on one side of the holding member 62
, The continuation condition satisfaction display section 29 is inserted. The continuation condition satisfaction display portion 29 is held and protected by a protection member 63 fixed to the boss portion 62c of the pressing member 62.

The hit ball that has won the continuous winning opening passes while pushing away the sensing piece 60 from the opening window 52d.
During this passage, the continuation condition detection switch SW3 is operated, and a detection signal is generated for each ball. After this,
The ball is guided to the detection unit 31a of the count detector SW4 and detected one by one together with the hit ball that has won the normal winning opening 82. Further, as shown in FIG. 8, a continuation condition satisfaction display section 29 is attached to the back plate 52. The continuation condition satisfaction display section 29 is disposed so as to face the opening window 52b. This continuation condition satisfaction display section 29
Are driven to light in response to a detection signal from the continuation condition detection switch SW3. As a result, the player can know that the special condition for granting the right to continue or extend the specific mode described above is established.

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 back surface of the back plate 52. This boss 52f is shown in FIG.
As shown in the figure, the support shaft 65a of the transmission member 65 is supported by the mounting piece 64 so as to be vertically rotatable. Transmission member 6
Reference numeral 5 is in the shape of a letter "H". The tip is the slot 52
It is projected forward from a. Further, the distal end of the transmission member 65 is configured to abut on the upper surface of the rear end of the operating piece 51c. The operating piece 51c is formed in the special fluctuation winning port 51 (FIG. 7). The operating end of the plunger 66a of the electromagnetic solenoid SOL is in contact with the upper end of the transmission member 65. The electromagnetic solenoid SOL serves as a drive source for the special variation winning device 5.

In FIG. 9, when the electromagnetic solenoid SOL is in the non-driving state and is stationary, the return spring 66b pushes down the plunger 66a, which pushes the transmission member 65 downward. Then, as imagined by a dotted line in FIG. 9, the rear end side of the spring operating piece 51c is pushed down, and the special fluctuation winning opening 51 is closed. As a result, the opening 50a is closed, and the special fluctuation winning 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 66a is driven upward. For this reason, the pressing force of the transmission member 65 is released, and the special fluctuation winning port 51 falls forward by its own weight. As a result, the opening 50a is greatly opened, and the special fluctuation winning opening 80 is opened temporarily.

As described above, the special variation winning device 5
Is electrically opened and closed according to the occurrence of a specific mode in the variable display device 4 and the right to continue.

Next, an embodiment of the control portion of the pachinko gaming machine to which the present invention is applied will be shown. FIG. 10 shows an overall hardware configuration of a control device 100 for a pachinko gaming machine according to the present invention.

FIG. 11 is a timing chart showing the waveform of the reset pulse φt and the operating state of the CPU 210. FIG. 12 shows a means for generating the reset pulse φt. FIG. 13 shows details of the vicinity of the I / O unit 240 of the control device 200. FIG. 14 shows the configuration of the scale generating means 260 in the I / O unit 240.

First, in FIG. 10, the control device 200 of the pachinko gaming machine 300 described above is configured by using a program storing CPU (central processing unit: microcomputer) 210 which is realized as a semiconductor integrated circuit device. .

That is, the control device 200 shown in FIG.
Is a CPU 210, a ROM (read-only storage device) 22
0, RAM (random access memory) 230, address decoder 240, I / O (input / output) unit 25
0, clock signal generating means 280, reset signal generating means 290, address bus LA, data bus LD, logic gate G1 and the like.

An 8-bit type (model number: Z80) is used as the CPU 210. This CPU 210
Are address terminals (A0 to A15) and data terminals (D0 to D)
And 7) functional terminals such as a read control terminal RD, a write control terminal WR, a clock terminal CK, and a reset terminal R. Another important function terminal is an interrupt input terminal (not shown). However, here, the interrupt terminal is not used. Instead, a reset terminal R is used. How to use the reset terminal R will be described later. The CPU used here
210 (Z80) has 16 address terminals (A0 to A1).
5) has an address space of 64 kbytes. However, what is used here is only about 2 KB.

The ROM 220 stores the program executed by the CPU 210 and fixed data. This RO
The M220 has a storage capacity of 2 kbytes. The capacity of 2 kbytes corresponds to the CPU 210 (Z8
Compared to the address space of 64), the capacity is very small.

The RAM 230 provides a work area (work area) for the CPU 210 and a storage area for variable data. The RAM 230 is of a static type. Its storage capacity is kept very small,
Only 128 bytes. In this case, since 128-byte RAM is difficult to obtain, 1-kbyte RAM is actually used. By fixing and killing the upper address terminal of the 1-kbyte RAM on the power supply potential side, the actually usable storage capacity is reduced to 128 bytes.

As described above, the ROM 220 and the RAM
Each storage capacity of 230 is kept very small. This makes it possible to surely eliminate the risk of a soft error called a so-called bug (insect), and to significantly increase the possibility of malfunctions such as CPU runaway or jumping into an infinite loop. You will be able to reduce it. As a result, extremely high reliability can be obtained even under severe use environments, both electrically and physically.

Furthermore, ROM 220 and RAM 230
By minimizing the storage capacity of each of the above, it becomes difficult to modify the program by additionally writing a program. Even if the remodeling is performed, it is easy to find and check it because the storage capacity is small. As a result, it is possible to prevent pachinko gaming machines from being abused due to unauthorized modification.
The effect is also obtained at the same time.

The address decoder 240 is the CPU 210.
The address data (A0 to A11) generated from the above are decoded to generate a large number of alternative selection signals S1 to 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 / W
D) is issued from the CPU 210. Both signals (RD / W
D) is ORed with each other by the logic gate G1. The logical sum becomes a control signal of the address decoder 240.

A part (S8, S9) of the selection signals S1 to S9 output from the address decoder 240 is the ROM.
220 and a chip select signal of the RAM 230. The other selection signals S1 to S7 are used to control an input / output circuit in the I / O unit 250 described later. That is, here, a so-called memory mapped I / O system in which input / output channels are arranged in an address space is employed. By adopting this memory-mapped I / O method, it is possible to perform arbitrary input / output operation by performing a simple process of accessing a specific address without performing a complicated procedure process of opening / closing an input / output channel. I / O operation is performed from the circuit.

The memory-mapped I / O method has a problem that a part of the address space is occupied and narrowed by the I / O area.
Adoption in computer systems was difficult. However, in the control device 200 of this embodiment, as described above, since the respective storage capacities of the ROM 220 and the RAM 230 are very small, the above-described problem does not need to be considered at all.

The I / O unit 250 is the control device 200.
And an interface (I / F) between the game machine main body 300 and the game machine main body 300. In this I / O unit 250,
As will be described later, a large number of input / output circuits are provided.
The operation of each input / output circuit is individually controlled by the selection signals S1 to S7. Although the individual configurations of the input / output circuit will be described later, for example, a decoder, a latch circuit, a driver, a buffer gate, an amplifier (amplifier) and the like are used.

The clock generating means 280 uses the crystal unit Xtal (4 MHz) as the frequency reference,
For example, a high-precision clock pulse φk of 2 MHz is generated. This clock pulse φk is applied to clock terminal CK of CPU 210.

The reset signal generating means 290 generates a reset pulse φt having a constant cycle from the clock pulse φk. This reset pulse φt is applied to the reset terminal R of the CPU 210. The reset signal generating means 290 is configured by a counter or the like in a simple and small scale.

In this case, the reset pulse φt has a duty width, that is, a pulse width, of the CPU 210.
Has a length that can be reliably reset. The pulse generation interval, that is, the cycle is set so as to be surely longer than the processing time required for the CPU 210 to execute all the program instructions stored in the ROM.

FIG. 11 shows the waveform of the reset pulse φt and the operating state of the CPU 210 with respect to time.

The reset pulse φt shown in FIG.
It has a pulse width of μs and a period of 3 ms. This 15
The pulse width of μs is a time sufficient to surely reset the CPU 210. Also, the period of 3 ms is
The time is sufficient for the CPU 210 to execute all the instructions stored in the ROM 220.

Further, as shown in FIG. 11 in correspondence with the reset pulse φt, the CPU 210 is forced to a complete initial state after each execution of a series of program commands written in the ROM 220. It will be reset to. As a result, if the CPU
Even if there is a malfunction such as the runaway of the 210 or the jump into an infinite loop, the normal operation state can be automatically returned immediately by resetting every 3 ms. As a result, the worst situation such as runaway or jump into an infinite loop, which is most feared in the control system by the CPU, can be surely avoided. In other words, a kind of fail-safe works here, and at least the CPU2
Only the 10 normal operating states are ensured to be maintained. In this way, the required reliability as a pachinko gaming machine is ensured.

Further, since the reset interval of the CPU 210 has a constant cycle, the number of resets is set to R.
By storing in the AM 230, the function of a so-called soft timer can be easily configured. Furthermore, the reset interval is, for example, 3 ms.
Therefore, a relatively long timer time, for example, several seconds to several tens of seconds can be configured very simply and simply by allocating a small storage area of about 1 byte or 2 bytes. . For example, if the reset interval is 3 ms, RA
By assigning 1 byte of the M area to the timer area, the timer time from 3 ms to 0.768 seconds can be obtained (3 ms × 256 = 768 ms = 0.76).
8 seconds). If 2 more bytes are allocated, 3ms to 1
A timer time up to 96.608 seconds can be obtained (3 ms × 256 × 256 = 196608 ms = 19
6.608 seconds).

As a result, for example, the RAM area is only 1
Even if there are only 28 bytes, a large number of timer functions required to individually control various functions in the pachinko gaming machine main body 300 can be easily configured.
Incidentally, the above-mentioned special variable prize winning device 5 (FIGS. 2, 6 to 6)
The relatively long timer-time of several seconds to several tens of seconds required to control the operation of FIG.
It can be obtained in the M region.

In FIG. 11, the halt state (standby state) is maintained from the time when the program command is executed once until the next reset. The halt state is set by executing a halt instruction at the end of the program. That is, the end of the above program ends with a halt instruction.

FIG. 12 shows a configuration example of the reset pulse generating means 290 (FIG. 10) for generating the reset pulse φt. As shown in FIG.
0 can be easily configured by the spare frequency dividing circuit 291, the counter 292, and the logic gate (AND gate) G2. In the figure, Cin is a count input, Cin
out indicates a count-up output.

With the above-described structure, the reliability of the pachinko gaming machine can be ensured and various functions necessary for controlling the operation of the pachinko gaming machine can be configured.

Next, the structure around the I / O unit 250 will be described.

As shown in FIG. 13, the I / O unit 250 has a buffer gate 251 as an input / output circuit.
Latch circuits 252 to 256 are provided. The operation of these input / output circuits (251 to 256) is controlled by the aforementioned selection signals S1 to S6. The input / output circuits (251 to 256) are connected to the CP via the data bus LD.
It is connected to U210 (Fig. 10). Data exchanged between the pachinko gaming machine main body 300 side and the control device 200 side is loaded on the data bus LD. Further, in addition to the input / output circuits (251 to 256), a scale generating means 257 is provided. The operation of the scale generating means 257 is also controlled by the above-described selection signal S7.

Of the input / output circuits (251-256), the buffer gate 251 constitutes an input circuit. The buffer gate 251 receives detection signals from various detecting means (SW1 to SW4, etc.) provided on the pachinko gaming machine main body 300 side, and receives a data bus LD in the control device 200.
Put on. In this case, as the detection means, there are the start switch SW1, the stop switch SW2, the continuation condition detection switch SW3, and the 10-count detector SW4 (FIGS. 3 and 7).

The input / output circuits (251-256)
Of these, the latch circuits 252 to 256 form an output circuit.
Further, the latch circuits 252 and 254 therein each include a decoder. These decoders decode the respective display data of the light emitting diode segment type displays LEDA to LEDE on the pachinko gaming machine main body 300 side. The display data is stored in C via the data bus LD.
It is given from the PU 210.

The function of each output circuit (252 to 256) is as follows.

That is, the latch circuits 252 and 253 are
The segment type displays LEDA to LEDD of the variable display device 4 (FIGS. 2 to 5) described above are driven to display by a dynamic method. The display data is provided from the CPU via the data bus LD. Each latch circuit 252, 2
53 includes a driver 26 for increasing the driving force of the output.
2,263 are attached respectively.

The latch circuit 254 is a segment type display L
The EDE is driven for display. As described above, this indicator LEDE displays the number of times the special right is continued when the specific mode of “big hit” occurs. The display data is provided from the CPU via the data bus LD.

The latch circuit 255 individually drives the memory display lamps LED1 to LED4 by the light emitting diodes. The lighting control data is given from the CPU via the data bus LD. This memory display lamp LED1
As described above, the LED 4 is used for displaying the number of retained hit balls in the specific winning openings 7 and 8 (FIGS. 2 and 3).

The latch circuit 256 individually drives the drive source and the display means on the pachinko gaming machine main body 300 side through the driver 266. The drive source in this case is an electromagnetic solenoid 66 for opening and driving the special variation winning device 5 described above.
(FIG. 9). The display means in this case is, for example, the continuation condition satisfaction display unit 29 (FIGS. 3 and 9) attached to the special variable winning device 5 described above.

The scale generating means 257 generates a sound source having a predetermined scale. The generated sound source is an amplifier 267
And is given to the speaker SP for generating a sound effect on the pachinko gaming machine main body 300 side. The scale of this sound source is C
The setting is made by data provided from the PU via the data bus LD.

FIG. 14 shows the construction of the scale generating means 257.

As shown in the figure, the scale generating means 25
Reference numeral 7 is composed of a latch circuit 256a for holding scale setting data and a presettable counter 256b.

The latch circuit 256a holds scale setting data given from the CPU via the data bus LD. The latch circuit 256a reads and holds the data on the data bus DL when the selection signal S7 becomes valid. The held data is the feasible counter 25.
It is preset to the counting content of 7b.

The presettable counter 256b is a kind of down counter, and is decremented by 1 by the clock pulse φk. The initial count content is preset by the latch circuit 256a. When the preset count content is decremented to "0", the data held in the latch circuit 256a is newly preset each time.

Here, the presettable counter 25
The output state of the carry terminal (count output terminal) Crry of 6b is set to 0 every time the count content is decremented to "0".
The logic level changes alternately from H (high level) to L (low level) or from L (low level) to H (high level). As a result, from the carry terminal Crry, H
A signal that alternates between (high level) and L (low level) is obtained. Then, this signal is used as the above-mentioned sound source. This sound source is an amplifier 26
The amplified sound is provided to the speaker SP for generating a sound effect on the pachinko gaming machine main body 300 side. At this time, the scale of the sound source is determined by the preset value. Further, if the preset value is small, the transition cycle described above becomes long and the pitch becomes low. Also, if the preset value is small,
The period of the above-described transition becomes shorter, and the pitch becomes higher.

The preset value is the CPU
It can be variably set by 210 (FIG. 10). Thereby, the control device 200 can arbitrarily generate a sound effect such as a fanfare sound in the pachinko gaming machine main body 300. The presettable counter 257b may be an up counter.

Next, the software configuration of the above-mentioned control device 200 will be described together with its operation.

FIG. 15 shows the control device 200 (see FIG.
0, FIG. 11), and FIG. 16 shows an enlarged part of the process flowchart.

First, the following Table 1 shows the CP of the control device 200.
The memory map shows the allocation contents of the address space portion accessed by U210 (FIG. 10). The address is displayed in hexadecimal numbers from O to F.

In Table 1 below, the range of addresses accessed by the CPU 210 is the 64-kbyte address space (0000 to FFFF) of the CPU (Z80) 210.
Address) between 0000 and 4000.

Of these, 2 kbytes from addresses 0000 to 07FF are allocated to the ROM area. Also,
128 bytes from addresses 0800 to 087F are allocated to the RAM area. And 1000,180
0,2000,2800,3000,3800,400
The I / O area is assigned to each of the 0s by 1 byte. In this case, the gap between the I / O areas is not used. Therefore, the size (large size) of the address space substantially accessed by the CPU 210 is only about 2 kbytes.

[Table 2]

Next, the operation of the control device 200 described above will be described with reference to FIG. 15 and Tables 1 and 2 above.

In FIG. 15, the CPU of the control device 200
210 is the reset pulse φt (see FIGS. 10 and 1).
1, FIG. 12), forcibly reset by hardware. By this reset, the CPU is started from a completely initial state. The CPU activated from the initial state by resetting first starts access from the ROM 220 and sequentially reads and executes the program instructions stored therein. As a result, the series of processing shown in FIG. 15 is started.

When the execution of the program instruction is started, the stack pointer is first set (R1). Then, it is checked whether or not start data indicating the beginning of the backup area (addresses 0838 to 0843) and end data indicating the tail of the backup area are set (R2-R3-).
R14-R15).

Here, in the first operation after the controller 200 is cold started (started by turning on the power),
The program is initialized (R17). In this initial setting, for example, all variable data such as output data and count data stored in the I / O area is initialized. Thereafter, the start data and end data are set (written) (R11). The start data and the end data have a value that can reliably reflect a storage error in the RAM 230, such as A5 (10 in binary).
A value such as 100101) is used. Further, after transferring the initialized data to the backup area, the halt command is executed to stop the execution of the process by the CPU itself (R12-R13). Then, the next reset pulse φt
Have a reset by.

The operation state of the control device 200 is initialized as described above.

After the initialization of the control device 200, the CPU sequentially executes the main routines R1 to R13 each time the reset pulse φt is issued. In this main routine, the following processing is executed as shown in FIG.

R1: Set the stack pointer.

R2, R3: Check end data in the backup area.

R4: Input processing for detecting the rising edges of the start switch SW1, stop switch SW2, continuation condition detection switch SW3, and 10 count detector SW4 is performed. This is done by referring to the previous detection signal and each state of this time. The state of the previous detection signal is stored in the buffer area. This storage state is always updated anew.

R5: The number of operations of the start switch SW1 is stored. The variable display device 4 (FIGS. 2 to 7) described above is activated by the specific winning ball detection operation of the start switch SW1. In this processing routine, the number of winning balls, that is, the number of actuations of the start switch SW1 until the activated variable display operation of the activated variable display device 4 stops is stored. When the number of times of operation is stored, that is, when the stored value is 1 or more, the variable display device 4 is restarted after the variable display operation is completed. Then, when the variable display device 4 is restarted, the stored value is decremented by one accordingly. That is, in this processing routine, a process of preserving the right to start the game, which is caused by the winning of the specific winning opening 7, 8 (FIGS. 2 and 3), is performed.

R6: 10 Count detector SW4 is checked for fraud. The function of the 10-count detector SW4 is logically determined based on the input state from the detector SW4, whether or not the connection or wiring is damaged due to disconnection or short circuit.

R7: Update timer values of various timers stored in the RAM area.

R8: The operation parameter (scale data) of the scale generating means 257 is set. In this processing routine,
A process of outputting scale setting data for generating a sound effect such as a fanfare is performed.

R9: Performs control processing for various display means and electromagnetic solenoids. In this processing routine, blinking control of the above-described jackpot display illumination means 27 and continuation condition satisfaction display section 29 (FIGS. 3 and 8) and drive control of the electromagnetic solenoid SOL (FIG. 9) in the above-described special variation winning device 5 are performed. Is performed.

R10: Perform various determination and control processes relating to winning. Here, a series of processes related to the operation control of the variable display device 4 and the occurrence of a specific mode such as “big hit” or “medium hit” are performed. The details of the routine R10 are shown in FIG.

R11: Performs setting (writing) processing of start data and end data indicating the beginning and end of the backup area described above.

R12: Perform processing for transferring variable data such as output data to the backup area.

When the main routines R1 to R12 described above are executed once, the last processing routine R13 executes the halt instruction. As a result, the apparatus enters a standby state in which the continuation of the processing is stopped.

When the main routines R1 to R12 described above are executed, the end data may be lost due to some abnormality.
When an error occurs in the data, a branch is made from a routine R2-R3 for checking the end data to a routine R14-R15 for checking the start routine. Then, the branched routine R14
If an error occurs in the start data in -R15, the routine R17 for initializing the program is re-executed, and the state of the control device 200 is returned to the state immediately after the cold start. In this way, a fail-safe operation for guiding the control state of the control device 200 in a safe direction when an abnormality occurs is performed.
On the other hand, if the error occurs only in the end data and there is no abnormality in the start data, the routine R16 is executed so that the backed up data is re-transferred to the main work areas 0800 to 080A of the CPU. Become. As a result, when the degree of the error is small, the automatic return to the normal operation can be performed while the state of the control is preserved.

FIG. 16 is a detailed flowchart of the winning process routine R10. As shown in the drawing, the winning processing routine R10 is composed of subroutines R101 to R122, and performs processing related to a specific winning, that is, operation control of the variable display device 4 and a series of controls related to generation of the specific mode. The processing is executed according to the processing numbers from No. 1 to No. 8. That is, the above-mentioned start switch SW1, stop switch SW2,
Continuation condition detection switch SW3, 10 count detector SW
A processing number is set based on each detection state of No. 4. Then, by selectively executing a subroutine prepared corresponding to the set processing number, it is possible to perform a specific winning-related processing operation in the above-mentioned pachinko gaming machine.

Here, the processing number is No. 0 to No. 8 is set. In this case, the process No. 0, N0.1-No. 8
It is only checked whether or not the operation starting condition is satisfied, and the process related to the specific winning is not performed. Processing related to a specific winning is No. 1 to No. This is performed when any one of the processing numbers up to 8 is set. No. 1 to No. The following subroutines R111 to R118 are prepared corresponding to the respective processing numbers up to 8.

That is, the process number is No. When set to 1, the routine R111 is executed. In this routine R111, a process of activating the variable display device 4 based on the detection of the start switch SW1 is performed. After execution of this process, the next process number No. 2 is set.

The processing number is No. If it is set to 2, the routine R112 is executed. This routine R112
Then, a process of stopping the operation of the variable display device 4 stepwise based on the detection of the stop switch SW2 is performed. At this time, a process of partially inserting a randomly set time into the time until the display operation is stopped is performed. Thus, the display contents after the operation is stopped are randomized. After execution of this process, the next process number No. 3 is set.

The processing number is No. When it is set to 3, the routine R113 is executed. This routine R113
Then, a process of determining whether or not a specific mode has occurred based on the result of stopping the variable display device 4 is performed. The determination is made based on the stopped display contents. If the specific mode of “big hit” is determined, the processing number No. 5 is set. If the specific mode of “middle hit” is determined, the processing number No. 6 is set. In the case of other losses, the processing number No. 0 is set.

The processing number is No. When it is set to 4, the routine R114 is executed. This routine R114
Then, control processing when a specific mode of "big hit" occurs, for example, control for opening and driving the special variable winning device 5 is performed. In addition, a timer process is also performed, thereby limiting the opening drive time to a relatively long predetermined time (about 30 seconds). Further, blinking drive processing of the related display means is also performed. After the execution of this routine R114, the process number No. 7 is set.

The processing number is No. If set to 5, routine R115 is set. This routine R115
Then, by setting the operation parameters of the scale generating means 257, a fanfare sound generation process is performed in accordance with the generation of the specific mode of "big hit". This routine R11
After the execution of step 5, the processing number No. 4 is set.

The processing number is No. When it is set to 6, the routine R116 is executed. This routine R116
Then, control processing when a specific mode of “middle hit” occurs, for example, control for opening and driving the special variable winning device 5 is performed. In addition, a timer process is also performed, thereby limiting the opening drive time to a relatively long predetermined time (about 6 seconds). Further, blinking drive processing of the related display means is also performed. After the elapse of the predetermined time, the process number No. 0
Is set.

The processing number is No. When set to 7, the routine R117 is executed. This routine R117
Then, based on the detection of the continuation condition detection switch SW3, the special variable winning device 5 is re-driven. This process is executed when a specific mode of "big hit" occurs. After execution of this routine R117, the next processing number N
o. 8 is set. The processing number is No. If it is set to 8, the routine R118 is executed. In this routine R118, processing is performed after the state of "big hit" or "medium hit" ends. When the “middle hit” operation is completed, the processing number is set to No. with a delay time of about 1 second. Set to 0. When the operation of the "big hit" is completed, a delay time of about 3 seconds is provided. Set to 4. If the continuation condition is not satisfied, the processing number No. Set to 0.

Here, the series of winning-related processing described above is the processing number No. It is started by setting 1. This No. The processing number of 1 is set when the start switch SW1 is stored with the number of times of operation to ON (routines R109, R).
120).

As described above, while the processing number is being updated, the operation control of the variable display device 4 and the winning-related processing associated with the occurrence of the specific mode are performed.

FIG. 17 shows the structure of the variable display control section formed in the control device 200 described above. The control portion shown in the figure is a portion for controlling the variable display operation of the variable display device and the start and stop operations thereof. This control part is configured by software by the microcomputer described above.

The control portion shown in FIG. 17 firstly displays the display data updating means 0 for updating the display contents of the variable display device 4.
2 The display data updating means 02 has a specific value adding means 01 for repeatedly adding a specific value every 12 ms.
Is provided. Then, the adding means 01 to 12
Each of the LEDs A, B, and B of the variable display device 4 is determined by the addition result of a fixed number of digits (lower 3 digits) sequentially obtained every ms.
Each display content of C is decided every 12 ms. That is, the display content of the variable display device 4 is updated every 12 ms, and the updated data is given from the adding means 01. Further, 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 3-digit prime number. When the 3-digit prime number 137 is repeatedly added by the adding means 01 and only the lower 3-digit numerical values are taken out as effective numerical values, the following numerical values are sequentially obtained every 12 ms.

First, when a specific value of 137 is repeatedly added and the addition results for each addition are arranged in the order of occurrence, 137, 274, 411, 548, 685, 82.
2,959,1026,1233, ..., 13700,
27400, 137,000, 13713
A numerical value sequence having discrete values such as 7, 137274, ... Is obtained.

Here, if only the lower three digits of each numerical value that composes the numerical value sequence are taken out, 137, 274, 411, 5
48, 685, 822, 959, 026, 233 ...
・ ・ ・, 700, ・ ・ ・, 400, ・ ・ ・, 000, 137, 2
74, ..., It is possible to obtain a numerical sequence in which a numerical sequence consisting of a combination of three numbers appears as if they were randomly arranged and the numerical sequences of the same combination appear in a cycle. If another value other than 137 is taken for the above specific value,
A numerical sequence different from the above is obtained.

Furthermore, if a 3-digit prime number such as 137 is used for the above-mentioned specific value, the numerical string of the same combination is exactly 1
It is obtained once every 000. For example, paying attention to the numerical value of 137, this numerical value "137" is exactly 1 in 1000.
Appears one by one. The same applies when focusing on other numerical values.
During the 1000 times, the same number appears only once, that is, 999 consecutive different number combinations are obtained.

Therefore, as described above, the specific value adding means 01 for repeatedly adding the specific value is provided, and the adding means 01 is provided.
The display contents of the variable display device 4 are updated at random as if the display contents of the variable display device 4 are determined by the addition result of a fixed number (lower 3 digits) sequentially obtained from As a result, for example, it becomes possible to average out a specific combination of numbers in which a specific mode such as a “big hit” occurs at regular intervals.

As a result, with the relatively simple and simple structure, while ensuring the randomness in the display updating operation of the variable display device 4, the above-described specific mode actually appears within a relatively short finite game period. The probabilities can be averaged, which allows for fair service to the players. Further, by selecting the above-mentioned specific value, it is possible to set the probability that the specific mode appears in a predetermined range.

For example, among the above-mentioned 1000 kinds of combinations of numbers, "111", "333", "55" are assumed.
It is assumed that the specific number sequences of "5", "777", and "999" are set in a specific mode called "big hit". Then, these specific numerical sequences are distributed almost evenly in the numerical sequence as follows.

That is, in the above numerical sequence,
Between "111" and "333", "333" and "555"
Between, "555" and "777", and "777"
Between 206 and “999”, 206 non-specific numeral strings are respectively interposed. In addition, 176 non-specific numeral strings are interposed between “999” and “111”. As described above, the specific number strings are not adjacent to each other or close to each other, and are not extremely separated from each other. All the specific digit strings are arranged at substantially even intervals.

As a result, when the addition operation by the addition means 01 is performed 1000 times or slightly exceeding an integer multiple thereof, a different number string appears each time the addition of the number slightly exceeding 1000 is completed. With
The above-mentioned specific numeral string appears at an almost constant rate.
Thereby, it becomes possible to further equalize the frequency of occurrence of the specific mode of the “big hit”.

The specific value does not necessarily have to be "137", and may be another prime number or a numerical value other than the prime number (for example, a random number generated by a random number generation circuit), if necessary. Further, the adding means 01 mentioned here includes one that performs subtraction. Even if subtraction is performed instead of addition, the above-described effects can be obtained similarly.

Here, in the embodiment, as shown in FIG. 17, in addition to the above-mentioned configuration, the period from the start to the stop of the updating operation of the display data updating means 02 is 12
An unspecified timer TM2 for inserting an unspecified time between ms and 120 ms is provided.

[0192] Further, the time (12000 m) during which the addition result of the specific addition means 01 makes a round between the start of the updating operation of the display data updating means 02 and the stop thereof.
s), that is, the unspecified timer TM in order to insert a time slightly longer than the time (1000 × 12 ms = 12000 ms) corresponding to one cycle of the above-mentioned numerical sequence.
2, a specific time timer TM1 having a time measuring time of 12000 ms, that is, 12 seconds is provided.

As a result, each time the updating operation is stopped, the variable display device 4 stops just above the previous stop position and displays the combination of the numbers located at this stop position. become. In this case, the unspecified timer TM2 randomly determines only the amount that slightly exceeds the previous stop position. by this,
As described above, the combinations of the respective numbers in the above-mentioned numerical sequence appear almost evenly without any partial bias, and are stopped and displayed.

Further, with respect to the unspecified timer TM2, an unspecified time data storage area 08, an unspecified data generating means 06, and an unspecified time data selecting means 07 are provided.

The unspecified time data storage area 08 stores a plurality of types of time data (1 × 12 ms to 10 × 12 ms).
It is stored in the form of a one-digit integer value from 0 to 9 in a randomly distributed manner. This storage area 08 is allocated in the ROM 220. The unspecified data generating means 06 generates unspecified data having a random value. The unspecified time data selecting means 07 selects the time data in the storage area 08 according to the unspecified data provided from the unspecified data generating means 06, and the selected unspecified time timer TM2 is timerd with this selected time data. Set as a value. This makes it possible to highly randomize the number of times of addition by the adding means 01, and to provide the display content of the variable display device 4 with even better randomness.

On the other hand, the display data updating means 02 includes a plurality of data holding means 0 together with the specific value adding means 01.
2A, 02B, 02C are provided. The plurality of data holding means 02A, 02B, 02C are the plurality of segment type indicators LEDA to LEDC of the variable display device 4.
It is provided corresponding to. First data holding means 0
2A holds the numerical data of the lower third digit displayed by the corresponding first indicator LEDA. The second data holding means 02B is the second display L corresponding to this.
It holds the numerical data of the lower 2nd digit displayed by EDB.

Similarly, the third data holding means 02C
Holds the numerical data of the lower first digit displayed by the corresponding third indicator LEDC. With this, 1
Of the 3-digit effective addition output data (D0, D1D2) of the adding means 01, the third digit numerical data D2 is stored in the second holding means 02A, and the second digit is stored in the second holding means 02B. The numerical data D1 of No. 1 are input to the third holding means 02C, respectively. As a result, the variable display LEDA ~
Each display content of the LEDC is given by the addition result of the adding means 01 and is updated at a constant time (12 ms) in synchronization with the addition cycle.

Further, the display updating means 02 is provided with timers TM3 and TM4. This timer T
M3 and TM4 are each data holding means 02A, 02B, 0
2C update operation stop timing is set to a fixed time (120 m
s) Sequentially delay each. As a result, each indicator LED
The display update operation of A to LEDC is sequentially stopped from the end as if the rotation is stopped.

FIG. 18 shows the operation of each unit from the time when the display update operation of the variable display device 4 is started to the time when it is stopped, in correspondence with each other.

17 and 18, the specific time timer TM1 is a start switch S for a specific winning ball.
It is activated based on the ON setting of W1 or the storage of the ON (ON) setting frequency, and measures a predetermined specific time (12000 ms = 12 seconds). When the specific time timer TM1 finishes measuring the specific time (12000 ms) or when the stop switch SW2 is manually turned on (ON), the unspecified time timer TM2 is activated.

The unspecified time timer TM2 measures the unspecified time (12 ms to 120 ms) selected by the unspecified time data selecting means 07. When the time measurement ends, that is, when the unspecified time set in the timer TM2 elapses, the segment type display LEDA ~
The operation of sequentially stopping the update of each display content of the LEDC is started.

The segment type display LEDA to LED
The operation of stopping the update of each display content in D is performed in the following order. First, when the time measurement by the unspecified time timer TM2 ends, the first update of the display content of the display LEDA is stopped. Along with this, the first stop interval setting timer TM3 is started. The timer TM3 measures a fixed time (120 ms). This fixed time (120
ms) is the addition cycle of the addition means 01 (120 ms)
It is equivalent to 10 times more than. When the time measurement ends, that is, when a fixed time (120 ms) elapses after the display content update of the display LEDA is stopped, the second display LE
Updating of the display contents of the DB is stopped. Along with this, the second
The second stop interval setting timer TM4 is started. This timer TM4 also measures a fixed time (120 ms).
This fixed time (120 ms) also corresponds to exactly 10 times the addition cycle (120) of the adding means 01. Then, after the update operation of the first indicator LEDA is stopped, 2
When the 0th addition cycle (12 ms × 20 times = 240 ms) has passed, the display content update of the third LEDC is stopped.

As described above, the updating of the display contents of each of the segment type display devices LEDA to LEDD of the variable display device 4 is sequentially stopped at fixed time intervals (120 ms). At this time, before the stopping operation is performed, the unspecified time (12 ms to 120 ms) is inserted by the unspecified time timer TM2. As a result, the timing at which the variable display operation of the variable display device 4 activated by the start switch SW1 is stopped can be changed randomly regardless of, for example, the operation timing of the stop switch SW2. Along with this, the stop display contents of the segment type display devices LEDA to LEDD of the variable display device 4 are randomized. This randomized state surely appears even when the display update cycle of the variable display device 4 and its update stop interval are constant, or when all other operations are regularized. In this way, the operation of the variable display device 4 can be surely provided with randomness with a simple and simple structure in which only one unspecified component is provided.

Table 3 below shows an example of the structure of the unspecified time data storage area 08. As shown in Table 3, the unspecified time data storage area 08 stores ten types of time data represented by integers from 0 to 9. This one
The number of types of time data of 0 type is randomly distributed and stored in a significantly larger number (128) than the type of time.

[0205]

[Table 3]

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. Further, Table 5 shows the correspondence between each unspecified time data of 0 to 9 and the real time.

[Table 5]

FIG. 19 shows a configuration example of the unspecified data generating means 06.

As shown in the figure, the unspecified data generating means 06 comprises a reset number counting means 061, a refresh counter 062 in the microcomputer (Z80), and a logical operation means 063.
The reset number counting means 061 counts the number of resets of the CPU. The content C61 obtained by extracting its count value, especially its lower digit (corresponding to the last digit of the decimal number 0 to 9), is the time and clock pulse when the microcomputer is first activated by power-on. An unspecified numerical value is taken due to the accumulation of extremely slight frequency variations in. That is, it is randomized.

The refresh counter 062 is for refreshing the dynamic RAM, operates freely in the microcomputer, and cannot be operated from the outside. Therefore, the content C62 is also randomized, like the reset number counting means 061. Further, the logical operation means 063 performs logical operation processing on the two kinds of contents C61 and C62. The logical operation in this case is such that exclusive OR is performed. Then, the operation result of the logical operation means 063 is
It is used as the unspecified data.

In this case, as the calculation result, only the numerical value of the lower digit (the numerical value from 0 to 9 in decimal) is extracted and used as the unspecified data. Also,
The above-mentioned two kinds of contents C61 and C62 each have sufficient randomness by themselves. Therefore, its content C6
Alternatively, 1 or C62 may be directly used as the unspecified data. However, the logical operation means 06
3, the two types of contents C61 and C62 are logically processed with each other, whereby unspecified time data with higher randomness can be obtained.

In the above embodiment, all display contents of the variable display device are determined by the addition result of a fixed number of digits sequentially obtained from the adding means for repeatedly adding the specific value. The display content may be given from a counter or the like provided separately from the adding means, and the display content at the time of stop may be given from the adding means. Further, in the present embodiment, as an example of the gaming machine, the one applied to the pachinko gaming machine has been described, but as long as it uses the variable display device, it is not limited to the pachinko gaming machine,
It may be a game machine having a variable display device such as a slot game machine or an arrange ball machine.

As has been clarified in the above description of the embodiments, the gaming machine according to the present invention has a variable display device having a plurality of display portions and forming a game state, and a display content of the variable display device. In a gaming machine comprising display data updating means for updating corresponding data, and configured to generate a special game state and give a special profit when the display content of the variable display device is stopped in a specific mode, The display data updating means includes arithmetic means for adding or subtracting a predetermined value to or from a previous arithmetic value, and data corresponding to display contents when the variable display device is stopped, for each of the plurality of display sections of the variable display device. Display data holding means for correspondingly holding the data is provided, and data corresponding to at least display contents of the variable display device at the time of stop is uniquely defined based on the values sequentially obtained from the computing means. Since it is determined and held in the display data holding means, with a relatively simple and simple configuration, while ensuring the randomness in the display update operation of the variable display device, within a relatively short finite game period. For example, it is possible to average the probabilities that a specific mode such as "big hit" actually appears, and thereby to fair the service to the player.

Moreover, by appropriately selecting the value to be added or subtracted, it is possible to set the probability that the specific aspect will appear in a predetermined range.

Further, by providing the display data holding means for holding the display contents when the variable display device is stopped, the display contents of the variable display device are sequentially arranged with a time lag toward the determined display contents when the variable display device is stopped. It is possible to stop the game, which can increase the player's expectation that a specific mode may occur.
