A value obtained by multiplying the value divided by the number of pitches by 100 (a value calculated by dividing the number of pitches put out during normal times ÷ the number of out pitches during normal times x 100) is displayed as performance information (hereinafter referred to as "normal time ratio information"). Note that the displayed value at this time is a value rounded off to the first decimal place.
Therefore, each data of the number of balls paid out during normal time, the number of out pitches during normal time, and the normal time ratio information is stored in the corresponding areas of the RAM 40c (the storage area for the total number of prize balls during the specified period, the storage area for the number of out balls during the specified period, and the storage area for the specified ratio information). They are stored (memorized) in each. However, rather than simply permanently measuring and displaying performance information, the measurement is temporarily terminated when the total number of out pitches reaches a predetermined prescribed number (for example, 60,000). This prescribed number is not the total number of out pitches in the normal state, but the total number of out pitches during all game states (including during winning games) (hereinafter referred to as "number of out pitches in all states"). This all-state out pitch count is also measured in real time and stored in the corresponding area (all-state out pitch count storage area) of the RAM 40c. Hereinafter, for convenience of explanation, the storage area for the total number of awarded pitches during specific play, the storage area for the number of out pitches during play, the specific ratio information storage area, and the storage area for the total number of out pitches during specific play will be abbreviated as "measurement information storage area".

Then, the normal time ratio information at the end point is stored in a predetermined area (performance display storage area) of the RAM 40c (memorizes the current normal time ratio information), and then the measurement information storage area (normal time payout number, normal time out ball After clearing the number of out pitches in all states and the number of out pitches in all states), start counting again (start measuring the number of pitches paid out in normal times, the number of out pitches in normal times, the normal time ratio information, and the number of out pitches in all states). The performance display 34 displays the previous normal time ratio information (measurement history information) and the normal time ratio information currently being measured. In addition, it is possible to display not only the previous information but also the history of the time before the last time or the time before that (three times ago), and it is possible to appropriately determine how many times before the information is to be displayed.

(Production control command)
The main control board 40 is capable of transmitting various performance control commands including information regarding the special symbol variation display game, information regarding errors, etc. to the performance control board 41 depending on the processing state. However, in order to prevent fraud such as cheating, the main control board 40 only transmits signals to the production control board 41, and has a one-way communication configuration in which it is not possible to receive signals from the production control board 41. It has become.

Here, the production control command defines the function with a 2-byte structure consisting of a 1-byte length mode (MODE) and a 1-byte length event (EVENT), and in order to distinguish between MODE and EVENT, Bit 7 is set to ON, and Bit 7 of EVENT is set to OFF. When transmitting this information as valid information, a strobe signal is output corresponding to each of the mode (MODE) and event (EVENT). That is, when there is a command to be sent, the CPU 40a (main control CPU) sets and outputs mode (MODE) information for sending the command to the production control board 41, and after a predetermined period of time has elapsed from this setting, the CPU 40a (main control CPU) sends the command for the first time. The strobe signal is transmitted. Further, event information is set and output after a predetermined time has elapsed since the strobe signal was transmitted, and a second strobe signal is transmitted after a predetermined time has elapsed from this setting. The strobe signal is controlled to be active by the CPU 40a for a predetermined period to ensure that the CPU 41a (performance control CPU) can receive commands.

[2.2 Production control board]
The production control board 41 is mainly composed of a microcomputer equipped with a microprocessor with a built-in CPU 41a, a ROM 41b that stores production data required for production control processing, and a RAM 41c that functions as a work area and buffer memory. In addition, the sound control section (sound source IC), interface circuit with each section, random number generation circuit that generates random numbers for lottery for production, CTC for various time counting, watchdog timer (WDT) circuit, CPU 41a An interrupt controller circuit that provides an interrupt signal, an RTC (Real Time Clock) function section, a reset circuit, etc. are provided to control the overall production operation.

The CPU 41a performs arithmetic processing for various performance operations and controls each performance means based on the performance control program and the performance control commands received from the main control board 40. In the case of the gaming machine 1 of this embodiment, the presentation means includes the liquid crystal display device 20 (main liquid crystal display device 20M, sub liquid crystal display device 20S), optical display device 16a, sound generator 17a, and a movable body not shown. It becomes a role item.

The ROM 41b stores a control program for the performance operation by the CPU 41a and various data necessary for the performance operation control.
The RAM 41c is used as a work area used by the CPU 41a for various calculation processes, a table data area, a buffer area for various input/output data, processing data, and the like.

The main roles of this production control board 41 are receiving production control commands from the main control board 40, selecting and deciding production based on the production control commands, display control of the liquid crystal display device 20 (display data supply), and sound generation device 17a. This includes audio output control of the optical display device 16a, light emission control of the optical display device 16a, operation control of the movable accessory (drive control of the movable accessory motor 50), etc.

Since this production control board 41 also has a function as a control device for the liquid crystal display device 20, the production control board 41 also has functions as a so-called VDP (Video Display Processor), image ROM, and VRAM (Video RAM). The CPU 41a also functions as a liquid crystal control section.
VDP refers to a function that controls overall video output processing such as image development processing and image drawing.
The image ROM refers to a memory in which image data on which the VDP performs image development processing is stored.
The VRAM is an image memory area that temporarily stores image data developed by the VDP.

With these configurations, the production control board 41 generates various image data based on production control commands from the main control board 40, and outputs it to the main liquid crystal display device 20M and the sub liquid crystal display device 20S. As a result, various effects images are displayed on the main liquid crystal display device 20M and the sub liquid crystal display device 20S.
Here, the "liquid crystal display device 20" shown in FIG. 3 is the "main liquid crystal display device 20M." The illustration of the sub-liquid crystal display device 20S in FIG. 3 is omitted.

The production control board 41 also has a sound control section for the sound generation device 17a including a plurality of speakers 17, and the sound signal outputted by the sound control section is amplified by the amplifier section 17b and supplied to the speaker 17.
The production control board 41 also includes a lamp driver section 16b that functions as a light display control section for the light display device 16a including the decorative lamp 16, and a drive for a movable object motor 50 that operates a movable object (not shown). A motor driver section 50a (motor drive circuit) functioning as a control section is connected. The production control board 41 instructs the lamp driver section 16b and the motor driver section 50a to control the light display operation by the optical display device 16a and the operation of the movable accessory motor 50.

Further, an origin switch 51 and a position detection sensor 52 for monitoring the operation of the movable accessory are connected to the production control board 41.
The origin switch 51 is composed of, for example, a photointerrupter, and detects whether or not the movable accessory motor 50 is at the origin position. The origin position is, for example, a position where the movable body is not normally exposed on the board surface in FIG. 2. The performance control board 41 is capable of determining whether or not the movable accessory motor 50 is at the origin position based on the detection information of the origin switch 51.
Further, the performance control board 41 controls the operation mode of the movable accessory while monitoring the current operation position (for example, the amount of movement from the origin position) based on the detection information from the position detection sensor 52. Furthermore, the production control board 41 monitors malfunctions in the operation of the movable accessory based on the detection information from the position detection sensor 52, and if any malfunctions occur, they are detected as errors.

In addition, the production control board 41 is connected to operation detection switches for the production button 14a, the cross key 14b, and the decision button 14c shown as the operation unit 14. It is possible to receive operation detection signals from each.

Furthermore, the performance control board 41 is provided with a handle sensor 53 (touch sensor) for detecting whether or not the firing operation handle 15 shown in FIG. 1 is being touched by a player. The production control board 41 is capable of determining whether or not the firing operation handle 15 is touched by the user based on the detection information of the handle sensor 53.

Based on the performance control command sent from the main control board 40, the performance control board 41 selects (determines) a performance pattern by lottery or uniquely from among a plurality of types of performance patterns prepared in advance, and selects (determines) a performance pattern uniquely from a plurality of types of performance patterns prepared in advance. Various presentation means are controlled at the right timing to bring out the desired presentation. As a result, it is possible to display a performance image on the liquid crystal display device 20 corresponding to the performance pattern, to play sound from the speaker 17, and to drive the decorative lamp 16 to turn on and off. etc.) are developed in chronological order to realize a "direction scenario" in a broad sense.

Here, regarding the effect control command, the effect control board 41 (CPU41a) generates an interrupt process based on the input of the strobe signal transmitted by the main control board 40 (CPU40a), and receives and analyzes the command. Specifically, the CPU 41a executes a control program for command reception interrupt processing based on the input of the strobe signal described above, acquires a production control command, and analyzes the command contents in the interrupt processing realized thereby. conduct.
At this time, if an interrupt occurs based on the input of the strobe signal, the CPU 41a performs the processing even if an interrupt process based on another interrupt (timer interrupt process that is executed periodically) is being executed. The command reception interrupt processing is performed by interrupting the command reception interrupt, and even if other interrupts occur at the same time, the command reception interrupt processing is performed with priority.

<3. Overview of operation>
Next, an overview of the gaming operation of the gaming machine 1 realized by the control configuration as described above (FIG. 4) will be explained.

[3.1 Game status]
The gaming machine 1 is configured to be able to set a plurality of types of gaming states in addition to a jackpot game which is a special gaming state. In order to facilitate understanding of this embodiment, various game states will first be explained.

In the gaming machine 1, the game progresses in any one of the gaming states in which either the low probability state or the high probability state is combined with either the non-time saving state or the time saving state.

The low probability state is a state in which the probability of winning a jackpot lottery is relatively low, and the high probability state is a state in which the probability of winning a jackpot lottery is relatively high.
The non-time saving state is a state in which it is relatively difficult for game balls to enter the second starting port 24, and the time saving state is a state in which it is relatively easy for game balls to enter the second starting port 24. For example, the opening time of the second starting port 24 when winning the regular lottery is set longer in the time-saving state than in the non-time-saving state. However, if it is easier for the game ball to enter the second starting port 24 in the time-saving state than in the non-time-saving state, then for example, the winning probability of the regular drawing lottery will be higher in the time-saving state than in the non-time-saving state. It may be increased or the fluctuation time of the normal symbol may be shortened.

In this embodiment, the "normal state" refers to a low probability state and a non-time saving state, and corresponds to an initial state.

[3.2 Symbol variation display game]
(About special drawing reservation)
In the gaming machine 1, when a game ball enters the first starting port 23 or the second starting port 24, that is, there is a detection signal input from the first starting port detection sensor 23a or the second starting port detection sensor 24a. In this case, the random numbers (random numbers for jackpot determination, random numbers for special symbol determination, random numbers for fluctuation patterns) related to the special symbol fluctuation display game described later are obtained, and these random numbers are used as retention data and the maximum retention, which is a predetermined upper limit, is obtained. Up to a memory number (for example, a maximum of 4) can be stored in the special figure reservation storage area of the RAM 40c.
This special figure retention storage area is provided with special figure retention storage areas corresponding to the special symbol 1 side and the special symbol 2 side, that is, a special symbol 1 retention storage area and a special symbol 2 retention storage area.

These special figure reservation storage areas are provided with a reservation 1 storage area to a reservation n storage area (n is the maximum number of reservation memories; in this embodiment, n=4), and each of them stores reservation data for the maximum number of reservation memories. It can be stored. Note that the maximum number of reserved memories in the special figure 1 reserved storage area and the special figure 2 reserved storage area is not particularly limited. Further, all or a part of the maximum number of reserved storage numbers for each symbol may be different, and the number can be determined as appropriate depending on the gaming nature.
The game balls related to the reservation data stored in this special figure reservation storage area are also referred to as "retention balls." In order to clarify the number of reserved balls to the player, the dot display corresponding to the number of reserved balls of special symbol 1 and special symbol 2 on the composite display device 22c is lit up, or the liquid crystal display device 20 (main liquid crystal display A hold indicator provided as an icon image on the screen of the device 20M or the sub-liquid crystal display device 20S is displayed by lighting.

(Special symbol fluctuation display game)
In the gaming machine 1, based on predetermined starting conditions, specifically, when a game ball enters the first starting port 23 or the second starting port 24 (winning), the main control board 40 determines a "jackpot" by random number lottery. A lottery will be held. The main control board 40 starts a special symbol variation display game by displaying special symbols 1 and 2 on the special symbol display devices 22a and 22b in a variable manner based on the lottery result of the jackpot lottery, and after a predetermined variation time has elapsed. , the results are displayed on the special symbol display devices 22a and 22b, thereby ending the special symbol variation display game. In addition, unless there is a particular need, "special symbol 1" and "special symbol 2" are simply referred to as "special symbol" (sometimes abbreviated as "special symbol").

Here, in this embodiment, the jackpot lottery for the special symbol 1 based on winning in the first starting hole 23 and the jackpot lottery for the special symbol 2 based on winning in the second starting hole 24 are performed separately and independently. Therefore, the jackpot lottery result for special symbol 1 is displayed on the special symbol display device 22a, and the jackpot lottery result for special symbol 2 is displayed on the special symbol display device 22b. Specifically, in the special symbol display device 22a, on the condition that a game ball enters the first starting port 23, the first special symbol variable display game is started by displaying the special symbol 1 in a variable manner, On the other hand, in the special symbol display device 22b, on the condition that a game ball enters the second starting port 24, the special symbol 2 is displayed in a variable manner and a second special symbol variable display game is started. ing. Then, when the special symbol variation display game on the special symbol display device 22a or the special symbol display device 22b is started, after a predetermined variation time has elapsed, if the jackpot lottery result is a “jackpot”, a predetermined “jackpot” mode is displayed. In other cases, the special symbol being displayed in a variable manner is stopped and displayed in a predetermined "miss" manner, thereby informing the game result (big hit lottery result).

For convenience of explanation, the first special symbol variation display game on the special symbol display device 22a side will be referred to as "special symbol variation display game 1", and the second special symbol variation display game on the special symbol display device 22b side will be referred to as "special symbol variation display game 1". It is called "Special Symbol Fluctuation Display Game 2". Further, the "special symbol variation display game 1" and the "special symbol variation display game 2" are simply referred to as the "special symbol variation display game."

When the jackpot lottery result becomes a "jackpot", that is, the special symbol fluctuation display game ends, and as a result, the special symbol is stopped and displayed in the "jackpot" mode on the special symbol display device 22a or the special symbol display device 22b. Then, a special game state (jackpot game) that is more advantageous to the player than during the special symbol variation display game occurs.

(Decorative pattern variable display game)
Further, when the above-mentioned special symbol variable display game is started, the decorative symbol variable display game is started by variably displaying decorative symbols (actual game symbols) on the main liquid crystal display device 20M. Various performances will be held in conjunction with the event. When the special symbol variable display game ends, the decorative symbol variable display game also ends, a predetermined special symbol indicating the jackpot lottery result is displayed on the special symbol display devices 22a and 22b, and the corresponding jackpot lottery result is displayed on the main liquid crystal display device 20M. Decorative patterns reflecting the results are derived and displayed. That is, the result of the special symbol variation display game is reflected and displayed by a decorative symbol variation display game that includes a decorative symbol variation display operation.

Therefore, for example, when the result of the special symbol variation display game is a "jackpot" (when the jackpot lottery result is a "jackpot"), an effect that reflects the result is developed in the decorative symbol variation display game. When the special symbol is stopped and displayed on the special symbol display devices 22a and 22b in a display mode indicating a jackpot (for example, 7 segments are displayed as "7"), the main liquid crystal display device 20M displays "left", " In each of the display areas "Middle" and "Right," the decorative symbols reflect the "jackpot" display mode (In each display area of "Left," "Middle," and "Right," three decorative symbols are displayed in the same state ( For example, the display is stopped at "7", "7", "7")).

Regarding the information necessary to execute the decorative symbol variation display game, first, the main control board 40, based on the fact that a game ball enters the first starting port 23 or the second starting port 24, specifically On the condition that the game ball is detected by the starting hole detection sensor 23a or the second starting hole detection sensor 24a and the starting condition (starting condition regarding special symbols) is met, it is determined whether it is a "jackpot" or a "miss". A jackpot lottery is performed, and a symbol lottery is performed to determine the types of special symbols to be finally stopped and displayed (jackpot type, loss type), and a variation pattern of the special symbols is determined based on the lottery results.
In the symbol lottery, if the jackpot lottery result is a "jackpot", one of a plurality of jackpot types is determined, and if the result is a "miss", one of a plurality of miss types is determined by lottery. However, there may be only one jackpot type and one loss type, and in that case, they may be determined without performing a lottery.
Then, the main control board 40 sends a command that includes at least information on the fluctuation pattern of the special symbol (fluctuation pattern information (for example, information on the jackpot lottery result and the fluctuation time of the special symbol, etc.)) as a production control command that specifies the processing state. "Variation pattern designation command" is transmitted to the production control board 41 side. As a result, basic information required for the decorative symbol variable display game is sent to the performance control board 41.

The special symbol variation pattern information can include information specifying whether or not a specific advance notice effect (for example, a "reach effect" or a "pseudo-continuous effect" to be described later) will occur. To be more specific, the special symbol variation patterns are roughly divided into a "jackpot variation pattern" in the case of a jackpot and a "loss variation pattern" in the case of a loss, depending on the jackpot lottery result. These variation patterns include, for example, a 'reach variation pattern' that specifies the occurrence of a reach effect, a 'normal variation pattern' that does not specify the occurrence of a reach effect, and the occurrence (overlapping occurrence) of a pseudo-continuous effect and a reach effect. A plurality of types of variation patterns are included, such as ``reach variation pattern with pseudo-coupling'' and ``normal variation pattern without pseudo-coupling'' which specifies the occurrence of pseudo-coupling effects but does not specify the occurrence of reach effects. In addition, in order to secure the production time for the ready-to-reach effect and the pseudo-continuous effect, the variation time is usually set longer for the variation pattern that specifies the ready-to-reach effect or the pseudo-continuous effect than for the normal variation pattern.

The production control board 41 performs chronological display during the decorative pattern variation display game based on information included in the production control commands (here, the variation pattern designation command and the decorative pattern designation command) sent from the main control board 40. The content of the performance to be developed (performance scenario such as a preview performance) and the decorative pattern to be finally displayed (decorative stop pattern) are determined, and the decorative pattern is displayed in a variable manner according to the time schedule based on the variation pattern of the special symbol. A symbol variation display game is executed. As a result, the decorative symbols on the main liquid crystal display device 20M are displayed in a variable manner in synchronization with the variable display of special symbols on the special symbol display devices 22a and 22b, and the period of the special symbol variable display game and the decorative symbol variable display game are changed. The middle period has substantially the same time width. Furthermore, the effect control board 41 controls the main liquid crystal display device 20M, the optical display device 16a, or the sound generator 17a, respectively, in accordance with the effect scenario, and develops various effects in the decorative symbol variation display game. Thereby, the reproduction of images (image production) on the main liquid crystal display device 20M, the reproduction of sound effects (sound production), and the lighting and blinking driving of the decorative lamps 16, LEDs, etc. (light production) are realized.

In this way, the special symbol variation display game and the decorative symbol variation display game have an inseparable relationship, and the display results of the special symbol variation display game are reflected in the decorative symbol variation display game. , these two symbol variation display games may be regarded as equivalent symbol games. In this specification, the above two symbol variation display games may be simply referred to as "symbol variation display games" unless otherwise necessary.

(About Futu reservation)
In the gaming machine 1, when a game ball passes through the normal symbol gate 26, that is, when a detection signal is input from the normal symbol gate detection sensor 26a, a random number related to the normal symbol fluctuation display game (for determining a normal symbol hit) is input. A random number) is acquired, and this random number is stored as pending data in the standard figure pending storage area of the RAM 40c up to a maximum pending storage number (for example, 4 pieces) which is a predetermined upper limit.
The general data reservation storage area is provided with a reservation 1 storage area to a reservation n storage area (n is the maximum number of reservation memories; in this embodiment, n=4), each of which stores reservation data for the maximum number of reservation memories. It is possible. Note that there is no particular restriction on the maximum number of reserved memories in the general figure reservation storage area.
The game ball related to the pending data stored in this general pattern holding storage area is also referred to as a "normal pattern holding ball." In order to clarify the number of balls on hold for normal patterns to the player, a dot display corresponding to the number of balls on hold for normal patterns on the composite display device 22c is lit up, or A hold indicator provided as an icon image on the screen of the liquid crystal display device 20S is displayed by lighting.

(Normal symbol fluctuation display game)
In the gaming machine 1, based on the passing of a game ball through the normal symbol gate 26, a "normal symbol winning lottery" is performed on the main control board 40 by random number lottery. Based on this lottery result, the normal symbol fluctuation display game is started by displaying the normal symbols expressed by the LEDs in a variable manner on the composite display device 22d, and after a predetermined variation time has elapsed, the result is displayed on the LED lighting and non-lighting. It is designed to stop and display in combination. For example, when the result of the winning lottery is "winning a winning map", a specific LED of the composite display device 22d is set to a specific lighting state (for example, all two LEDs are lit), depending on the type of hitting a winning map. status, or the LED on the "○" side among the LEDs expressing "○" and "×" is in a lit state). In addition, in this embodiment, only one type is provided per general figure.

When this "normal hit" occurs, the normal electric accessory solenoid 25a (see Fig. 4) is activated, and the second starting port 24 is opened or enlarged, making it easy for game balls to flow in (starting port opening). state), and a gaming state (hereinafter referred to as "normal power open game") that is more advantageous to the player than when the second starting port 24 is closed occurs. In this normal power release game, the second starting port 24 is opened by the normal electric accessory 25 until a predetermined time period (for example, 5.7 seconds) has elapsed, or the number of game balls entering the second starting port 24 reaches a predetermined number. The winning area is opened or expanded until the number (for example, 10 pieces) is reached, and when any of these conditions is met, the second starting port 24 is closed, etc., a predetermined number of times (for example, once at most) It's about to be repeated.

[3.3 About jackpot]
Next, "jackpot" in gaming machine 1 will be explained.
In the game machine 1, for example, ``4R1'', ``10R'', and ``4R2'' are provided as the jackpot types, and when the result of the jackpot lottery is ``jackpot'', the lottery for the jackpot type is performed in the symbol lottery.
Note that the above notation "R" means the specified number of rounds (maximum number of rounds).

The jackpot type is a hit that triggers the operation of the conditional device. Here, the "condition device" is a device whose operation is a necessary condition for the operation of the accessory continuous operation device for playing a round game, and a specific combination of special symbols is displayed or a game ball is displayed. This refers to something that activates when passing through a specific area within the grand prize opening.

The jackpot game is played for a predetermined period of time (up to Opening time: For example, when 29.8) has elapsed or the number of game balls that have entered the first grand prize opening 27 or the second grand prize opening 28 reaches a predetermined number (maximum number of winnings), the first grand prize opening A "round game" in which the second jackpot opening 27 or the second jackpot opening 28 is closed is repeated for a predetermined number of rounds (number of rounds based on the jackpot type). Then, after the specified number of rounds has been completed, the jackpot game ends when a post-opening interval time (ending time) for notifying the end of the jackpot game has elapsed. Note that "s" after the number represents "second".

When a jackpot game is executed, the game state after the end of the jackpot game, the number of probability changes, and the number of time reductions are determined according to the game state at the time of winning the jackpot and the determined type of jackpot.
The probability variation number is set when the gaming state after the jackpot game is a high probability state. In the gaming machine 1, the high probability state after the jackpot game continues until the number of executions of the special symbol variation display game reaches the variable frequency (for example, 154 times), and the high probability state after the jackpot game continues until the number of executions of the special symbol variation display game reaches the variable frequency (for example, 154 times). When the symbol variation display game ends, the gaming state is set (transitioned) to a low probability state.
The time saving number is set when the gaming state after the jackpot game is the time saving state. In the gaming machine 1, the time-saving state after the jackpot game continues until the number of executions of the special symbol variation display game reaches the number of time-savings (for example, 150 times), and the special symbol of the number of time-savings is displayed without winning the jackpot in the jackpot lottery. When the variable display game ends, the gaming state is set (transitioned) to a non-time saving state.
However, the gaming machine 1 may be a "general probability variation machine" in which the probability variation number and the time saving number continue until the jackpot is won in the jackpot lottery (until the next time).
The time saving number may be the total number of executions of the special symbol fluctuation display game 1 and the special symbol fluctuation display game 2 (the total number of fluctuations of the special symbol 1 and special symbol 2), or the number of executions of either one ( For example, it may be the number of times the special symbol variation display game 2 is executed.

Here, in this embodiment, a plurality of loss types are provided for "loss" as well as the jackpot type. Specifically, three types of deviations are provided: "missing 1", "missing 2", and "missing 3".
As described above, when the result of the jackpot lottery is a "loss", a lottery of the type of loss is performed in the symbol lottery.

[3.4 About the performance]
(Production mode)
Next, the performance mode (performance state) will be explained. The gaming machine 1 of this embodiment is provided with a plurality of types of performance modes for presenting performances related to the gaming state, and is configured to be able to switch between the performance modes. Specifically, a production mode corresponding to the set gaming state is provided. In each production mode, the background display as the background of the fluctuating display screen of decorative symbols is displayed with a different background effect, so that the player can understand what kind of gaming state he or she is currently in. It has become.

The performance control board 41 (CPU 41a) has a functional unit (performance state transition control means) that controls transition between multiple types of performance modes. The production control board 41 (CPU41a) responds to a specific production control command sent from the main control board 40 (CPU40a), specifically, a production control command that includes gaming state information managed on the main control board 40 side. Based on this, the current gaming state is grasped in a manner that maintains consistency with the gaming state managed on the main control board 40 side, and it is configured to be able to control transition between a plurality of types of performance modes. Examples of the above-mentioned specific performance control commands include a variation pattern designation command, a decorative symbol designation command, and a game state designation command sent when a change occurs in the game state.

(Preview performance)
Next, the preview performance will be explained. The performance control board 41 executes various functions related to the current performance mode and the jackpot lottery result based on the contents of the performance control command from the main control board 40, specifically, at least the fluctuation pattern information included in the fluctuation pattern designation command. It is configured to be able to control the appearance of "notice effects". This kind of preview performance is used as a "stimulation performance" to suggest (notice) the level of expectation as to whether or not the jackpot type has been won (hereinafter referred to as "win expectation level"), and to arouse the player's expectation of winning. work. Typical preview performances include "reach performance,""pseudo-continuationperformance," and even "pre-read preview performance." The performance control board 41 functions as a preview performance control means that can control the execution (appearance) of these performances.

"Reach effect" refers to a performance mode that involves a reach state (fluctuating display mode that involves a reach state: reach variation pattern), and specifically, a method that derives and displays the final game result via a reach state. It refers to the style of performance. The reach effects include multiple types of reach effects associated with the degree of expectation of winning. For example, there are cases where the expectation of winning is relatively higher than when a normal reach effect appears. This kind of reach performance is called ``super reach performance.'' Many of these "super reaches" have a relatively longer production time (fluctuating time) than normal reaches in order to stimulate expectations of winning. In addition, normal reach and super reach include multiple types of reach effects. Super Reach includes multiple types of Reach effects such as Super Reach 1, 2, 3, and 4, and the winning expectations for Super Reach 1 to 4 are as follows: Super Reach 1 < Super Reach 2 < Super Reach 3 < Super Reach It has a relationship of ``Reach 4''.

"Pseudo-continuous performance" refers to a performance mode that involves a pseudo continuous variation display state (pseudo-continuous variation) of decorative symbols. It refers to a variable display mode in which a display operation is repeated one or more times, in which a part or all of a decorative pattern is temporarily stopped, and then the decorative pattern is re-variably displayed from the temporarily stopped state. In this respect, it is different from the later-described "pre-read preview performance (continuous preview performance)" which is developed over multiple symbol change display games. Basically, the occurrence rate (appearance rate) of such "pseudo-links" is determined so that the higher the number of pseudo fluctuations, the higher the expectation of winning.For example, depending on the number of pseudo fluctuations, It is made easier to select performances to arouse expectations such as reach.

"Pre-reading notice effect" (hereinafter sometimes abbreviated as "pre-reading notice" or "pre-reading effect") is, based on the result of pre-reading judgment, before the fluctuation display of the target symbol is performed. It means an effect that alerts you to the possibility of being controlled in an advantageous state. Note that "advantageous state" means a state advantageous to the player.
Specifically, the look-ahead effect is mainly based on the pending display mode or the first execution of the pending balls (unexploited pending balls) that have not yet been used for the execution of the symbol variation display game (special symbol variable display operation). The game is performed in a manner that can notify the winning expectation level in advance before the reserved ball is used in the symbol variation display game by using the background effect of the symbol variation display game. In addition, in the symbol variation display game, in addition to the above-mentioned "reach effect", there are various effects such as the so-called "SU (step up) notice effect", "timer notice effect", "resurrection effect", and "premier notice effect". It occurs and is designed to liven up the game content.

Here, with reference to FIG. 5, the "suspended change notice performance" as an example of the above-mentioned pre-read notice performance will be described.
In the case of the gaming machine 1 of this embodiment, the upper display area of the screen of the main liquid crystal display device 20M includes a display area for displaying a decorative symbol variation display game (displaying a decorative symbol variation display effect and a preview effect). In addition, the display area on the lower side of the screen includes a holding display area 60 (holding display areas a1 to d1) that displays the number of balls held on the special symbol 1 side, and a special symbol. A holding display area 61 (holding display parts a2 to d2) for displaying the number of balls held on the second side is provided. The presence or absence of a reserved ball is notified by a predetermined reserved display mode. In Figure 5, the presence or absence of held balls is shown in the lighted state (with held balls: "○ (white circle mark)" shown in the figure) or in the unlit state (no held balls: the broken line circle shown in the figure), and the current number of held balls. An example is shown in which information regarding

Displays regarding the presence or absence of held balls (holding display) are displayed in order of occurrence (order of winning), and in each held display area 60, 61, the leftmost held ball is the same as all held balls in the held display. It is displayed as the first (that is, the oldest) pending ball on the time axis. Further, on the left side of the holding display areas 60 and 61, a changing display area 62 is provided to show the holding balls currently being used in the special symbol changing display game. In the case of the present embodiment, the changing display area 62 is configured such that an image in which an icon of a game currently being played pending K is displayed on top of the icon of the catch J. That is, when the variable display of special symbol 1 or special symbol 2 is started, the icon (icon image) of the oldest pending display area a1 or a2 displayed in the pending display areas 60 and 61 is displayed as a pending display during game execution. The icon K is moved onto the icon of the catch J in the changing display area 62, and this state is maintained for a predetermined display time.

When a reserved ball occurs, the main control board 40 specifies the pre-read judgment information related to the jackpot lottery result and the number of reserved balls at the time of pre-read judgment (the existing number of reserved balls, including the currently reserved ball). A “pending addition command” is transmitted to the production control board 41.
In the case of this embodiment, the above-mentioned pending addition command is composed of 2 bytes, and the pending addition command includes data on the upper byte side that makes it possible to specify the number of reserved pitches at the time of look-ahead judgment, and lower byte side data that makes it possible to specify the look-ahead judgment information. It consists of data on the byte side.

Here, as understood from the above description, in this embodiment, based on the fact that a game ball enters the first starting port 23 or the second starting port 24 and a new held ball is generated, the held ball is A jackpot lottery for a symbol variation display game related to balls is performed as a pre-read determination. The main control board 40 suspends and stores the prefetch determination information obtained by such prefetch determination in the corresponding storage area of the RAM 40c.

Here, the look-ahead determination information specifically refers to the jackpot lottery result (jackpot lottery result at the start of fluctuation) executed when the reserved balls are used in the symbol fluctuation display game in the main control board 40, and the fluctuation This is game information obtained by pre-reading and determining the fluctuation pattern at the start. In other words, this information includes at least the information on the pre-read judgment of the jackpot lottery result at the start of the fluctuation (pre-read validity information), and the information on the pre-read judgment on the symbol lottery result (pre-read symbol information) and the fluctuation at the start of the fluctuation. It is possible to include information on which a pattern has been pre-read and determined (pre-read variation pattern information). What kind of information to send the pending addition command to the production control board 41 can be determined as appropriate depending on the content to be notified in the advance notice.
It is assumed that the pending addition command includes pre-read validity information, pre-read symbol information, and pre-read variation pattern information.

When the production control board 41 receives the above-mentioned pending addition command transmitted by the main control board 40, it performs a "pre-read notice production" as part of the display control process related to the above-mentioned pending display, based on the pre-read determination information included therein. Performs production control processing related to. Specifically, a "pre-read preview lottery" is held to determine whether or not the pre-read preview performance can be executed, and if the lottery is won, the pre-read preview performance is made to appear.

Note that the "pre-read fluctuation pattern" obtained by the pre-read judgment when a held ball occurs does not necessarily have to be the "fluctuation pattern at the start of fluctuation" obtained when the held ball is actually subjected to a fluctuation display operation. . For example, to describe a typical case where the fluctuation pattern at the start of the fluctuation is a fluctuation pattern that specifies "Super Reach 1", in this case, the content specified by the look-ahead fluctuation pattern is "Super Reach 1". Rather than specifying the type of reach performance itself, it is possible to specify the essential "super reach type".

In the case of the present embodiment, if you win the pre-read preview lottery, the pending icon that is the target of the pre-read preview among the pending icons in the pending display areas a1 to d1 and a2 to d2 will be displayed as a normal hold display, for example. "Pending display change" that can change from white (normal pending display mode) to a pending display (special pending display mode) with blue, green, red, and danger patterns (or special colors and patterns such as rainbow colors) for advance notice. A pre-read preview performance (also referred to as a "pending change notice") of "Kei" will be performed.
FIG. 5 shows an example in which the hatched reservation ball in the reservation display section b1 has changed to a special reservation display. Here, the display of the pending icon in blue, green, red, and danger pattern means that the expectation of winning is high in this order.In particular, the display of the pending icon with the danger pattern indicates that the expectation of winning the jackpot is extremely high. It is said to be a premium hold icon that will be displayed.

<6. Configuration example>
An example of the configuration of the gaming machine 1 will be described below.

The gaming machine 1 of the embodiment has the following (configuration A1-1).
(Configuration A1-1)
The gaming machine 1 is a gaming machine equipped with a board, and the board includes an input connector into which a predetermined power supply voltage is input, a backup power generation circuit that generates a backup power source based on the predetermined power supply voltage, and a backup power source. an output connector to output, a first wiring pattern connecting the backup power generation circuit to a terminal to which a predetermined power supply voltage is input in the input connector, and a terminal to which the backup power is outputted to the backup power generation circuit and the output connector; and a second wiring pattern connecting the two, the second wiring pattern being shorter than the first wiring pattern.

In the case of this (configuration A1-1) concept, the board corresponds to the payout control board 42, the predetermined power supply voltage reduction corresponds to 5V DC voltage (DC5VA), the input connector corresponds to connector CN1, and the backup power supply corresponds to the backup power supply. It corresponds to the power supply (VBB), the output connector corresponds to the connector CN3, and the terminals to which a predetermined power supply voltage is input in the input connector correspond to the 15th pin to the 18th pin (CN1_15 to CN1_18) of the connector CN3. Further, the first wiring pattern corresponds to wiring patterns L5b_1, L5a_1, L5b_3, and LVb_1, and the second wiring pattern corresponds to wiring patterns LVb_1 and LVb_2.

As shown in FIGS. 18 to 20, when the 5V DC voltage (DC5VA) is input to the 15th pin to the 18th pin (CN1_15 to CN1_18) of the connector CN1, it passes through the wiring pattern L5b_1 on the soldering surface 42b. It is input to two through holes T5_1 and T5_2. The 5V DC voltage (DC5VA) input to the two through holes T5_1 and T5_2 is guided to the component surface 42a side via the through holes T5_1 and T5_2, and then passes through the wiring pattern L5a_1 to the two through holes T5_3 and T5_4. is input. The 5V DC voltage (DC5VA) input to the two through holes T5_3 and T5_4 is guided to the solder surface 42b side via the through holes T5_3 and T5_4, and then input to the noise removal filter FLT3 through the wiring pattern L5b_2. . The 5V DC voltage (DC5VA) input to the noise removal filter FLT3 is input to the anode terminal of the diode D5 of the backup power generation circuit 80, output from the cathode terminal, passes through the wiring pattern LVb_1, and is input to the positive terminal of the electrolytic capacitor C13. Ru. The total length of the wiring pattern through which 5V DC voltage (DC5VA) passes from the 15th to 18th pins (CN1_15 to CN1_18) of connector CN1 to the backup power generation circuit 80 (diode D5) is approximately 290 mm. There is.

On the other hand, as shown in FIG. 19, the backup power supply (VBB) is generated by the backup power generation circuit 80 based on the 5V DC voltage (DC5VA) and is stored in the electrolytic capacitor C13. When the 5V DC voltage is no longer supplied to the positive terminal of the electrolytic capacitor C13 due to a power cut, the backup power supply (VBB) is input from the positive terminal of the electrolytic capacitor C13 to the noise removal filter FLT4 through the wiring pattern LVb_1 on the solder surface 42b.

Output. The total length of the wiring pattern from the electrolytic capacitor C13 to the fourth and sixth pins (CN3_4, CN3_6) of the connector CN3 through which the backup power supply (VBB) passes is about 56 mm.

Therefore, the total length (approximately 56 mm) of the wiring pattern through which the backup power supply (VBB) outputted to the main control board 40 passes is the total length (approximately 56 mm) of the wiring pattern through which the 5V DC voltage (DC5VA) input from the power supply board 70 passes. It is shorter than the length (approximately 290mm). In this way, by making the wiring pattern of the backup power supply (VBB) output to the main control board 40 shorter than the wiring pattern through which the 5V DC voltage (DC5VA) input from the power supply board 70 passes, the backup power supply (VBB) is outputted to the main control board 40. ) can be reduced, and the stability of backup of the RAM 40c during power-off can be improved.

The backup power generation circuit 80 (electrolytic capacitor C13, diode D5) is arranged slightly above the left side of the payout control board 42, and at a position closer to the connector CN3 than the connector CN1 (just below the connector CN3).

This makes it possible to design a shorter design. In this way, it is possible to shorten the wiring patterns LVb_1 and LVb_2 through which the backup power supply (VBB) output to the main control board 40 passes, reduce the influence of noise, and improve the stability of backup of the RAM 40c when the power is cut off.

Furthermore, the diode D5 is placed closer to the connector CN1 than the electrolytic capacitor C13. Further, diode D5 is arranged such that its anode terminal is closer to connector CN1 than its cathode terminal. Thereby, in the payout control board 42, the wiring pattern when connecting the 15th pin to the 18th pin (CN1_15 to CN1_18) of the connector CN1 and the diode D5 forming the backup power generation circuit 80 can be shortened.

The backup power supply (VBB) input to the resistor R22 is input to the 20th pin of the integrated circuit IC7 via the resistor R22 and the wiring pattern LVb_4. The total length of the wiring pattern from the electrolytic capacitor C13 to the 20th pin of the integrated circuit IC7 through which the backup power supply (VBB) passes is approximately 228 mm.

Therefore, the total length (approximately 56 mm) of the wiring pattern through which the backup power supply (VBB) output to the main control board 40 passes is the total length of the wiring pattern through which the backup power supply (VBB) input to the integrated circuit IC 7 passes. (approximately 228mm). In this way, by shortening the wiring pattern of the backup power supply (VBB) output to the main control board 40, noise entering the backup power supply (VBB) output to the main control board 40 can be reduced, and it is possible to prevent power outages. It is possible to reliably back up the RAM 40c at any time.

Specifically, as shown in FIG. 9, on the payout control board 42, the integrated circuit IC7 is arranged slightly lower on the left side. The backup power generation circuit 80 is placed closer to the connector CN3 than the integrated circuit IC7.

In this way, by arranging the backup power generation circuit 80 closer to the connector CN3 than the integrated circuit IC7, in the payout control board 42, the wiring pattern LVb_1, through which the backup power supply (VBB) output to the main control board 40 passes, It becomes possible to design LVb_2 short. In this way, the wiring patterns LVb_1 and LVb_2 through which the backup power supply (VBB) outputted to the main control board 40 passes are shortened to reduce the influence of noise, thereby ensuring more reliable backup stability of the RAM 40c when the power is cut off. I can do it.

In the case of this concept (configuration A1-3), the connector CN3, which is an output connector, outputs a 5V DC voltage (DC5VA) and a backup power source (VBB) to the main control board 40. That is, the 5V DC voltage (DC5VA) input from the power supply board 70 is branched at the wiring pattern L5b_2, and one side is directly supplied to the 10th pin and 12th pin (CN3_10, CN3_12) of the connector CN3, and the main control board 40 and the other is supplied to the backup power generation circuit 80 to generate backup power (see FIG. 19).

In such a case, one of the branched 5V DC voltages (DC5VA) will be supplied to the connector CN3, and the other will be supplied to the backup power generation circuit 80, so the 5V DC voltage (DC5VA) will be supplied to the vicinity of the connector CN3.
