Description

  The present invention relates to a gaming machine that enables a setting change of a payout rate (machine discount).

  For example, slot machines, which are a lot of gaming machines installed in pachinko halls, etc., when a player inserts medals and the start lever is operated, multiple reels rotate, and each reel stops according to the operation of the stop button To do. When the winning reels are established, such as the symbols of the reels that have been stopped are displayed, a game is provided for paying back to the player the number of medals according to the winning mode (winning combination) to the player. Yes.

  Generally, the slot machine is provided with an internal lottery means, and the reel pull-in control is performed so that the symbols of the winning combination lottery selected by the internal lottery means are displayed together. In other words, the probability that each winning combination is established and the game play rate of the gaming machine are largely determined by the internal lottery probability.

  The game play rate is the expected value of the number of medals expected to be won by winning a prize against the number of medals (or the number of pachinko balls, etc.). As a result, the player can only obtain the same result regardless of the machine. For this reason, normally, by making the internal lottery probability variable, it is possible to set and change the payout rate step by step within an appropriate range.

  In conventional gaming machines, it is premised that the change in the ball-out rate is made outside the business hours of the hall. When a device for changing the ball-out rate (setting change device) is activated, the RWM (Lead The contents of the data stored in the work area of the write memory) (for example, conditions relating to the operation of the condition device such as BB and variable data such as variable data such as the number of inserted medals) are cleared, and the gaming state is initialized. It was.

  According to the conventional gaming machine that enables the setting change of the payout rate, there are the following problems. For example, when the slot machine is in a gaming state advantageous to the player (BB or RB condition device operation, etc.), the hall side intentionally activates the setting change device, so that the gaming state is not known to the player. It was possible to lift and unfairly profit. Conversely, if the setting change device is activated in a game state that is relatively unfavorable for the player (for example, a low-probability RT game), an earlier advantageous game state (for example, a high-probability RT normal game) that is continued thereafter It was also possible to migrate to.

  In this way, if the hall side can be manipulated artificially to some extent by the initial conditions of the game resumed after changing the setting of the play rate, if this is abused, for example, the gaming machine is in an advantageous state before the opening of the hall opening hours There was a risk of allowing fraud, so-called “morning”, that was charged into the company.

  In response to such a problem, the present inventor continues and resumes the game by returning the game state before the setting to the game state before the setting even if the setting change device for the play rate is activated while the gaming machine is in operation. The knowledge that the means is effective was obtained. However, when this is embodied, it becomes necessary to prevent various problems in the progress of the game (for example, the game content and the production operation do not match before and after the setting). The maximum demand was made to completely restore the gaming state of the game.

  For example, in a general slot machine, the main control board controls the progress of the game, and the sub control board controls the game effects in cooperation. Normal commands and data related to the gaming state sent from the main control board to the sub control board are temporarily stored in the transmission queue buffer (cycle memory), and the FIFO (first in first out) method is used for every predetermined clock interrupt. Commands and data waiting to be sent are sent in bytes. When such a transmission mode is adopted, if the above-described setting change device becomes operable at an arbitrary timing while the gaming machine is operating, matching of commands and data managed respectively on the main control board and the sub control board A means to guarantee sex was needed.

  The present invention has been made in view of these problems, and completely restores the game state before setting the payout rate without incurring a mismatch of operations including a plurality of control boards or peripheral devices. An object of the present invention is to provide a gaming machine that makes it impossible to manually operate the game conditions that are resumed after the return of the setting, and thus to prevent wake-up or cheating by the player.

  In order to solve the above-described problem, the invention described in claim 1 is controlled by a control device, and the control device includes a setting change device for changing a setting of a payout rate, and an update used as a work area in game progress. An RWM (read / write memory) capable of holding the contents of the RWM and returning the gaming state before the setting change, wherein the control device The normal command data generated as needed according to the request is made to wait in the transmission queue buffer constructed in the RWM, and the normal command data that is waiting is sequentially transmitted to the peripheral device by a predetermined length every clock interrupt processing of a predetermined period. And a normal command data transmission unit configured to transmit the special command data to the transmission queue buffer without accessing the transmission queue buffer. Characterized in that the command data is provided separately special command data transmission means for transmitting to the peripheral device.

  According to the gaming machine of the first aspect, the output device is provided separately from the normal command data transmitting means that is provided in the control device and transmits normal command data waiting in the transmission queue buffer according to the progress of the game to the peripheral device. The rate setting changing device includes special command data transmitting means for transmitting special command data to the peripheral device. Since the special command data transmission means does not access the transmission queue buffer of the RWM, untransmitted normal command data waiting in the transmission queue buffer is held. Thus, depending on the operation of the setting change device, normal command data that has not yet been sent to the RWM of the control device is not destroyed. Therefore, the gaming state before setting can be completely restored without causing a mismatch in the operating environment between the control device and the peripheral devices.

  A second aspect of the present invention is the gaming machine according to the first aspect, wherein one of the peripheral devices is a sub-control device that controls an effect operation related to the game.

  According to the gaming machine of the second aspect, the consistency of the operating environment between the control device and the sub-control device after the return of setting of the payout rate is ensured. Therefore, the game state before setting can be completely restored without causing a mismatch between the game and the rendering operation.

  A third aspect of the present invention is the gaming machine according to the first or second aspect, wherein the game machine is activated when the main power source is turned off, and at least the return address of the program counter in the control device when the power source is turned off is the RWM. The setting change device restarts the game after setting the program counter to return at least the return address saved to the RWM.

  According to the gaming machine of claim 3, the power-off processing means saves at least the return address of the program counter to the RWM when the power is cut off, and the setting change device for the payout rate returns the return address to the program counter. Let the game resume. Thereby, in the game after setting the payout rate, it is possible to reproduce the game state when the power is turned off, that is, before the setting, and to prevent illegal acts such as morning.

  As described above, according to the gaming machine of the present invention, it is possible to eliminate the destruction, loss, etc. of unsent normal command data that may have been caused by the operation of the setting change device for the payout rate, and the control device after returning to the setting It is possible to ensure the consistency of the operating environment between the device and the peripheral device (sub-control device). Thereby, the game state before the setting can be completely restored without causing a mismatch between the game content and the rendering operation. In addition, it is possible to make an artificial operation of the game condition resumed after the return of the game play rate set is restored, and to prevent a morning act or an illegal act by the player.

  The slot machine 1 configured as described above enters a standby state when a winning is made in the previous game and the payout of medals is completed, or when a loss is confirmed in the previous game. In this state, when the bet button 12 is pressed, medals are bet on the game from medals (credits) stored therein, and the game starts. When the start lever 13 is tilted in the game start state, the main control board 21 starts to rotate the reels 10a, 10b, and 10c all at once. At the same time, the winning combination is internally lottery, and the result is stored in the RAM (internal lottery flag).

  Next, when the player presses the stop buttons 14a, 14b, and 14c in an arbitrary order, the main control board 21 sequentially stops the corresponding reels accordingly. When the main control board 21 detects that all the reels 10a, 10b, 10c have stopped, the combination of symbols displayed on each reel is a combination of symbols related to the winning combination stored in the internal lottery flag. It is determined whether or not it matches. When they match, the winning combination is confirmed, and the acquired number of medals according to the type of winning combination is added to the credit. When the credit exceeds the upper limit due to winning, the main control board 21 controls the hopper unit 23 and pays out the surplus medals to the tray unit 4.

  As described above, the player of the slot machine 1 performs a game operation for rotating / stopping the reels 10a, 10b, and 10c, and loses the bet medals if the symbols displayed on the display window 8a are not variably displayed. If the winning combination is achieved with the combination of symbols, it is possible to obtain more medals than the betted number, so that it is possible to enjoy a win / loss game with an interest in increasing medals.

  Next, the control system of the slot machine 1 will be described in detail. Here, FIG. 3 is a block diagram showing a control system configuration of the slot machine 1. 3, the control system of the slot machine 1 has an electric circuit board such as a main control board 21 at the center, a sub-control board 33, a central display board 36, a spinning device board 100, and a power supply board 250. Are connected to each other by a wiring cable including an external data bus and an external control bus.

  The main control board 21 is a microcomputer-based control board including a CPU 211, a PROM (Programmable Read Only Memory) 212, a RAM (Random Access Memory) 213 as an RWM (Read / Write Memory), and the like. The CPU 211 performs overall processing according to the stored main program, thereby controlling the overall operation of the slot machine 1. In addition to the semiconductor memory described above, the CPU 211 is connected to chip sets such as an interrupt controller 214, an external bus interface 215, and a clock generator 216 via internal buses, and these are integrated into one IC package. Are mounted on the main control board 21. Further, the RAM 213 is configured so that a drive current is supplied from a backup power supply (not shown) and the stored contents are retained even when the main power supply device 25 of the slot machine 1 is in a power-off state.

  A random number generator 217 is connected to the CPU 211 of the main control board 21. The random number generator 217 is a circuit that includes an oscillation element and a counter that counts a short-cycle pulse signal generated by the oscillation element, and the CPU 211 executes the random number generator 217 at a timing related to a predetermined game operation. A value indicated by the counter is acquired as a random value, and a table lottery such as winning combination and effect pattern is performed based on the random value as will be described later.

  The central display board 36 functions as a relay board for the medal sensor 38a built in the medal selector 38, the bet button 12, the start lever 13, the stop buttons 14a, 14b, and 14c, and the CPU 211 of the main control board 21 In the clock interrupt that is activated every (several milliseconds), the outputs of these sensors and switches are read in parallel to the input ports. The central display board 36 is mounted with the above-described setting button 53 and the 7-segment LED constituting the numerical value display units 51 and 52, and further the memory counter logic 361 for displaying the numerical value on the numerical value display unit 52 is mounted. ing.

  Here, as shown in FIG. 4, the setting button 53 for performing the setting change operation for the output ball setting value is provided at the left end portion of the central display board 36 on the back surface side of the front door 3. Therefore, for example, unless the person in charge of setting the hall unlocks the front door 3 and opens it, the setting change of the payout rate cannot be made structurally.

  For example, as shown in FIG. 5, the memory counter logic 361 provided on the central display board 36 serves as a display buffer capable of inputting / outputting data via an external data bus connected to the main control board 21. Similarly to the memory 361a, it is connected to the external data bus, and switches the data stored in either the memory counter 361b for inputting the switch signal of the setting button 53 to the clock and the memory 361a or the memory counter 361b to switch the numerical value display section 52. A switching unit 361c to be displayed on the display, a decoder 361d for decoding the data transferred via the switching unit 361c for decimal 7-segment display, and a numerical display unit 52 (7-segment LED) by current-amplifying the decoded data signal. And a driver 361e that drives to light up).

  Each time the setting button 53 is pressed, the memory counter 361b sequentially increments (counts up) numerical values from “1” to “6” (counts up) and stores and holds them. In addition, the memory counter 361 b is set with the ball output setting data by the main control board 21 via the external data bus, and can output the held data to the main control board 21 in response to a request signal from the main control board 21. Be controlled.

  The switching unit 361c is also controlled by the main control board 21. Normally, in a game, a mode for synchronously displaying the data on the number of acquired medals, the error code, and the like transmitted at any time via the external data bus on the numerical display unit 52 is set. Has been. In addition, when the setting change device or setting confirmation device for the payout rate is activated, the mode (data set value) held by the memory counter 361b is switched to a mode in which the numerical value display unit 52 displays the data.

  Next, the sub control board 33 decodes the selected sound source data, the CPU 331, the semiconductor memory for the system including the ROM 332 and the RAM 333, the sound source data memory 334 for storing sound source data such as musical sounds used for production. An AMM decoder (Amusement Music Decoder with Sequencer) 335 that reproduces sound signals of a sequence, an image data memory 336 that similarly stores image data for production, and an image processing DSP that decodes the image data and outputs an image digital signal (Digital Signal Processor) 337 and the like are configured with a circuit via an internal bus.

  The sub-control board 33 includes LEDs, which are light sources such as the upper lamp 5a and corner lamps 5b, 5c, speakers 31a, 31b, 43a, 43b constituting the sound emitting units 6a, 6b, 17a, 17b, and the liquid crystal display unit 7. Is connected externally. The CPU 331 of the sub-control board 33 turns on or blinks the LEDs in response to receiving the effect command signal from the main control board 21, drives the speakers 31 a, 31 b, 39 a, 39 b, and displays a moving image on the liquid crystal display unit 7. Control to display.

  The liquid crystal display unit 7 is a device that is unitized by including an image control board on which a VDP (Video Display Processor), a video RAM, and the like are mounted on a liquid crystal panel as a display. The image control board generates a video signal based on an image digital signal output from the image processing DSP 337 of the sub-control board 33, and drives to display an image on the liquid crystal panel.

  The main control board 21 controls the stepping motors 102a, 102b, and 102c directly connected to the shafts of the reels 10a, 10b, and 10c via the spinning device board 100. That is, the CPU 211 outputs pulse data as a rotation command signal to the spinning device substrate 100, and supplies the four-phase driving pulse signals that are current-amplified by the spinning device substrate 100 to the stepping motors 102a, 102b, and 102c. Thus, control of rotation and stop of each reel 10a, 10b, 10c is performed independently. The CPU 211 resets the rotational position data every time it receives a signal from each of the reference position sensors 101a, 101b, and 101c, and accurately grasps the rotational position of each reel based on the pulse data sent based on this. I have control.

  The main control board 21 is connected to the payout motor 231 and the payout sensor 232 of the hopper unit 23 through the power supply board 250 of the main power supply 25. When paying out medals by the hopper unit 23, the CPU 211 drives the payout motor 231 to release the medals one by one, and when the actual payout number counted by the payout sensor 232 reaches the planned payout number and matches, Assuming that the payout is completed, the drive of the payout motor 231 is stopped. The same control is performed when a medal lending operation is performed, and a predetermined number of medals are paid out to the player through the medal payout opening 16 by the hopper unit 23.

  As shown in FIG. 6, the main power supply device 25 has a main switch 251 and a setting key switch 252 arranged on the front panel. The main switch 251 is a rocker (seesaw) switch and functions as a power switch for turning on and off the power of the entire slot machine 1.

  The setting key switch 252 is a switch that allows a switch operation when a predetermined key KEY is inserted and is turned on when the key KEY is rotated 90 degrees to the right. As will be described later, if the setting key switch 252 is turned on when the main power supply 25 is turned off, and the main switch 251 is turned on in this state, the setting change device for the payout rate is activated. Further, when the setting key switch 252 is turned on while the main power supply device 25 is energized (the main switch 251 is turned on), the setting confirmation device is activated by an interrupt process.

  Next, processing related to the setting change of the payout rate, which is a characteristic part of the present invention, will be described in detail. Here, FIG. 7 is a block diagram showing the configuration of software related to the setting change of the payout rate.

  As shown in the figure, the PROM 212 of the main control board 21 has a main program 212a, a clock interrupt I / O routine 212b, a power-off processing routine 212c, and a power-on processing program 212d in storage areas of predetermined addresses, respectively. , The power-off recovery processing program 212e, the appearance setting change program 212f, the internal lottery program 212g, and other various subprograms (program modules that are called by the main program 212a or activated by interrupt processing) are fixed in firmware. Has been.

  Further, in the PROM 212, a role lottery table 212h referred to by the internal lottery program 212g (internal lottery means) and, for example, a symbol in which a reel symbol and a position (number of rotation steps) are associated with each other are not shown. Table map data such as a reference table and an acquired medal number table in which the number of medals to be paid out for a winning combination (combination of symbols) is associated and stored are also stored.

  The RAM 213 is used as a stack area 213a for stacking register contents of the CPU 211, a stack pointer save area 213b, a transmission queue area 213c for storing normal commands and the like, and transmitting them to the sub-control board 33, a work area 213d, and the like. Each storage area is assigned to a predetermined address. In addition, a storage area for storing the output setting data 213e referred to as the output setting value and various other variable data 213f related to the game progress of the slot machine 1 is assigned to a predetermined address. Similarly, a storage area for storing a power-off flag 213g, a payout setting flag 213h, an internal lottery flag 213i, other various status flags 213j, checksum data 213z, and the like is assigned to a predetermined address.

  Examples of the various other variable data 213f used in the slot machine game include variables relating to medal management such as the number of inserted medals (the number of bets), the number of stored medals (the number of credits), the number of acquired medals, Are variables related to reel control such as pulse data, rotational position data, display symbol number, etc., variables related to medal payout control such as the actual payout number of medals by the hopper unit 23, and the like. Other examples of the various state flags 213j include flags indicating the switch output states of operation switches and sensors such as the start lever 13 and the stop buttons 14a, 14b, 14c.

  Next, the control operation by the main control board 21 based on each subprogram shown in FIG.

[Clock interrupt I / O processing]
The clock interrupt I / O routine 212b stored in a predetermined address of the PROM 212 is called an interrupt routine that is called based on an interrupt signal having a fixed period (for example, 1.87 msec period) generated by the clock generator 216 (see FIG. 3). It is. Each time this clock interrupt is activated, the CPU 211 of the main control board 21 reads the state of the input port to which the start lever 13, stop buttons 14a, 14b, 14c, the medal sensor 38, etc. are connected, and these operation switches. And output signals from sensors.

  In addition, the CPU 211 transmits a transmission waiting command and data in the transmission queue buffer 213c ′ (cycle memory) constructed in the transmission queue area 213c of the RAM 213 to the sub control board 33 byte by byte using a FIFO (first in first out) method. To do. For example, according to the example of FIG. 8, the CPU 211 has some commands and data to be transmitted to the sub-control board 33 based on the operation of the operation switches and sensors in the main process (these are “normal command”, “ "Normal data") is set in the transmission queue buffer 213c 'as needed. Such normal commands and normal data are composed of 2 or more bytes, but are transmitted in units of 1 byte by one clock interrupt (depending on the specifications of the data bus, CPU, etc.). In other words, the CPU 211 divides the normal command and normal data pieces stored in the transmission queue buffer 213c ′ into the upper byte and the lower byte from the previously set value every time the clock interrupt is activated. , Sequentially transmitted to the sub-control board 33.

  In the slot machine 1, examples of normal commands transmitted from the main control board 21 to the sub control board 33 include a medal insertion command, a rotation start reception command, a rotation start command, a rotation stop reception command, a rotation stop command, and a symbol. Examples include a display command, a medal payout start command, a medal payout completion command, an RT command, and the like. Similarly, the normal data transmitted includes credit (stored number) display data, payout display data, RT game number data, error display data, and the like. Such normal data is composed of two bytes (or more) of a predetermined identification code (upper byte) and its value (lower byte).

[Power off processing]
Next, the flowchart shown in FIG. 9 represents processing by the power-off processing routine 212c called by the interrupt processing when the main switch 251 is turned off (power-off) while the main power supply device 25 is energized.

  In this power-off process, first, other interrupts such as the above-described clock interrupt are prohibited (step S101), and the data contents of the program counter of the CPU 211 and other general-purpose registers are stacked and saved in the stack area 213a of the RAM 213. (Step S102). Then, the pointer value (address) indicated by the stack pointer of the CPU 211 is transferred to the stack pointer save area 213b of the RAM 213 and saved (step S103).

  Next, after setting the power-off flag 213g indicating that the power-off processing has been performed (step S104), the checksum of the RAM 213 is calculated and set in the checksum data 213z (step S105). Then, writing to the RAM 213 is prohibited (step S106), the process is completed, and the process waits for the power supply to be restored (power-on).

[Power-on processing]
Next, the flowchart shown in FIG. 10 represents processing by the power-on processing program 212d that is activated first when the main switch 251 is turned on and the power is turned on.

  In this power-on process, first, a temporary stack pointer is set to an unused address where a register or the like has not been saved (step S201), so that subsequent pre-processing can be performed. The CPU 211 checks whether or not the setting key switch 252 is turned on (step S202). If it is determined that the setting key switch 252 is turned on (step S202: YES), whether or not the output ball setting flag 213h is set. Is checked (step S203).

  The payout setting flag 213h is a flag that is set when the payout rate setting changing device is activated, that is, in the payout setting changing process described later. When this flag is set (step S203: YES), the CPU 211 forcibly shifts to the power-off recovery process and returns and restarts the game at the time of power-off. This avoids redundant activation of the setting change device.

  If the power is turned off while the setting change device is in operation and the setting change device is activated again in this state, the game condition when the power is turned off saved in the RAM 213 is lost. In this case, after the setting is changed, the initial game state when the power is turned off is not reproduced and is initialized. However, if this operation is misused, the initial condition setting of the game that is resumed after the setting is restored can be intentionally operated.In order to solve this inconvenience, the operation of the setting change device is flag-managed. Duplicate activation is prohibited.

  If the CPU 211 determines that the main switch 251 is turned on while the setting key switch 252 is off (step S202: NO), the CPU 211 checks the power-off flag 213g (step S204). When the power-off flag 213g is set (step S204: YES), the CPU 211 determines that the power-off process has been normally performed as described above, and proceeds to a power-off recovery process described later. If the power-off flag 213g is not set (step S204: NO), the power-on initialization process is executed (step S205), and the game progress main process by the main program 212a is performed under default initial conditions. Start.

  Here, the power-on initialization process called in step S205 will be described with reference to the flowchart shown in FIG. In the power-on initialization process, the CPU 211 first initializes the storage area excluding the appearance setting data 213e in the RAM 213 to a default value (step S301). Next, a default initial value is loaded into the register of the CPU 211 and reset (step S302). Then, clock interrupts and other interrupts are permitted (step S303), and input (reading) of sensors and switches provided in the slot machine 1 is enabled.

[Power failure recovery processing]
Next, the flowchart shown in FIG. 12 represents processing by the power-off recovery processing program 212e that is started when the main switch 251 is turned on after the power-off processing is performed.

  In the power-off recovery process, the CPU 211 first checks whether the address stored in the stack pointer save area 213b of the RAM 213 is within a predetermined appropriate range (step S401). When the address is out of the proper range (step S401: NO), the above power-on initialization process is executed (step S407), and the game progress main process by the main program 212a is started. Also, the checksum of the RAM 213 is calculated and compared with the stored checksum data 213z to check whether it is normal (step S402). If the CPU 211 determines that the checksum data in the RAM 213 does not match and is a data error that cannot be recovered (step S402: NO), the CPU 211 executes the power-on initialization process (step S407), and the game progresses. Start the main process.

  If the address stored in the stack pointer save area 213b is within an appropriate range (step S401: YES) and the checksum data is normal (step S402: YES), the stored address is used as the stack pointer. The setting is returned (step S403). Further, the activation of the clock interrupt is permitted (step S404), and the state input (reading) of the sensors and switches provided in the slot machine 1 is made possible. In addition, the waiting data (such as an untransmitted command) accumulated in the transmission queue buffer 213c ′ is sequentially transmitted to the sub-control board 33 by permitting the clock interrupt. Next, the CPU 211 initializes (resets) a predetermined unused area of the RAM 213 to a default value (step S405).

  Here, the unused area of the RAM 213 refers to an unused work area excluding a save area such as a register, an area for storing various variable data related to game progress, and various state flags. In this power-off recovery process, the use area of the RAM 213 that holds the game conditions (variable data, status flag) is held without being cleared.

  In step S406, the contents of the register at the time of power-off saved in the stack area 213a of the RAM 213 are restored. At this time, the address (return address) at the time of power-off is loaded from the stack area 213a into the program counter of the CPU 211. By completing the power-off recovery process, the conditions at the time of power-off are reproduced and maintained, and the game is resumed.

[Outlet setting change processing]
Next, a process (outlet setting change process) by the output ball setting change program 212f related to the operation of the output rate setting change device will be described with reference to the flowcharts shown in FIGS.

  In the payout setting change process, first, it is checked whether or not the address stored in the stack pointer save area 213b of the RAM 213 is within a predetermined appropriate range (step S501). When the address is out of the proper range (step S501: NO), the above power-on initialization process is executed (step S503), and the game progress main process by the main program 212a is started. Further, the checksum of the RAM 213 is calculated and compared with the stored checksum data 213z to check whether it is normal (step S502). If the CPU 211 determines that the checksum data in the RAM 213 does not match and is a data error that cannot be recovered (step S502: NO), the CPU 211 executes the power-on initialization process (step S503), and the game progresses. Start the main process.

  If the address stored in the stack pointer save area 213b is within an appropriate range (step S501: YES) and the checksum data is normal (step S502: YES), in order to avoid redundant activation of the setting change device. Then, the output ball setting flag 213h is set (step S504).

  In addition, the CPU 211 generates a payout setting start command and transmits it to the sub control board 33 (step S505). It should be noted that this outgoing ball setting start command is transmitted not by the above-described clock interruption routine (this is referred to as “normal command transmission mode”) but by the main process of changing the outgoing ball setting. In other words, the outgoing ball setting start command is transmitted in a transmission mode different from the normal command described above, and in this specification, such a command having a different transmission mode is referred to as a special command. Thus, by providing a transmission mode (this is called “special command transmission mode”) that is different from the normal command transmission mode in the progress of the main game, even if the setting change device for the play rate is activated, the transmission is performed. The waiting command and data stored in the queue buffer 213c ′ need not be altered or lost. Therefore, the game after the setting of the payout rate is completely returned, and the operating environment between the main control board 21 and the sub control board 33 after the setting return is matched.

  Next, the CPU 211 checks whether or not there are waiting commands and data stored in the transmission queue buffer 213c ', and transmits the untransmitted commands and data to the sub-control board 33 (step S507). Thereby, the commands and data managed by the main control board 21 and the sub control board 33 are matched.

  When all untransmitted commands and data in the transmission queue buffer 213c ′ are transmitted (step S507: YES), the CPU 211 controls the input of the switching unit 361c of the memory counter logic 361 to the memory counter 361b side to display a numerical value. The mode is switched to a mode for displaying the set ball set value on the part 52 (step S508). Further, by transferring the present ball setting data 213e stored in the RAM 213 to the memory counter 361b, the currently set ball setting value is displayed on the numerical value display unit 52 (step S509).

  Each time the setting button 53 is pressed, the memory counter logic 361 increments the data of the ball setting value set in the memory counter 361b one step at a time, and simultaneously displays the data on the numerical value display unit 52. Accordingly, the person in charge of setting the hall or the like while the setting changing device is operating presses the setting button 53 while looking at the numerical value displayed on the numerical value display unit 52, so that any level of “1” to “6” is obtained. It is possible to select a set value for the ball. When the desired output setting value is displayed, when the start lever 13 is returned from ON to OFF (step S510: YES), the data updated in the memory counter 361b is written in the RAM 213 as the output setting data 213e. (Step S511). As a result, the change of the payout setting value referred to by the internal lottery means described later is confirmed.

  Next, the CPU 211 transmits the payout setting data 213e to the sub control board 33 (step S512). Thereby, the set-out set value referred to by the internal lottery means of the main control board 21 and the set-out set value referred to by, for example, the effect lottery means of the sub-control board 33 coincide with each other, and a predetermined set-out ratio is guaranteed. The Also, at this stage, a payout setting completion command is transmitted to the sub control board 33 (step S513). In the step of transmitting the ball setting data 213e and the ball setting completion command to the sub-control board 33, since it is transmitted in a different transmission mode (special command transmission mode) different from the normal command and data described above, The contents of the transmission queue buffer 213c ′ used in the game are retained.

  Furthermore, the CPU 211 sets and restores the address stored in the stack pointer save area 213b to the stack pointer (step S514). Then, the unused area of the RAM 213 is initialized (reset) to a default value (step S515). Here, the unused area of the RAM 213 refers to an unused work area excluding a save area such as a register, an area for storing various variable data related to game progress, and various state flags. It should be noted that in this output setting change process, the used area of the RAM 213 that holds the game conditions (variable data, state flag) is held without being cleared.

  In step S516, the contents of the register at the time of power-off saved in the stack area 213a of the RAM 213 are restored. At this time, the address (return address) at the time of power-off is loaded from the stack area 213a into the program counter of the CPU 211. By completing such a game setting change process, the conditions at the time of power-off are reproduced and maintained, and the game is resumed.

[Internal lottery processing]
Next, table lottery processing by the internal lottery program 212g related to the operation of the internal lottery means will be described with reference to the flowchart shown in FIG.

  Here, the combination lottery table 212h fixed to the PROM 212 will be described. In the game of the slot machine 1, winning combinations having different symbol display forms such as big bonus (BB), regular bonus (RB), replay, bell,... Are prepared, as shown in FIG. The probability (internal lottery probability) of drawing each winning combination is determined in advance. Furthermore, the internal lottery probabilities for each winning combination are separately determined for each of the payout setting values “1” to “6”. The table shown in FIG. 16 is an example of a winning combination and an internal lottery probability that are referred to when the slot machine 1 is a base game, and is different in a special game where a winning is established with a higher probability such as a big game. The lottery table is referred to and the table lottery is performed.

  Based on the predetermined internal lottery probability, a plurality of role lottery tables 212h are provided for each of the payout setting values “1” to “6”. Here, FIG. 17 represents the configuration comparison of the number of numbers for each set value in the winning lottery table 212h. The numerical value is a coefficient proportional to the internal lottery probability, and the ratio obtained by dividing the numerical value by the number of random numbers that can be generated by the random number generator 217 (for example, 65536) coincides with the internal lottery probability. Accordingly, as shown in FIG. 17, a numerical value range of numbers based on internal lottery probabilities corresponding to each winning combination is assigned to one winning lottery table 212h.

  According to the example of the internal lottery probability shown in FIG. 16, when the set-out set value is “1”, for example, a numerical range of “0” to “221” is assigned to the BB of the numerical value “222”. For example, a numerical value range of “222” to “331” is assigned to the RB of the numeric value “110”. Similarly, when the output setting value is “2”, a numerical value range of “0” to “231”, for example, is assigned to the BB of the number “232”, and the RB of the number “115” is For example, a numerical value range of “232” to “346” is assigned. As described above, the larger the payout set value is, the higher the internal lottery probability is set. Accordingly, the numerical range corresponding to each winning combination is gradually set wider.

  The internal lottery process is started at a predetermined opportunity such as when the start lever 13 is operated, for example, and as shown in the flowchart of FIG. 15, the CPU 211 obtains a random number value from the random number generator 217 at the timing of the first step S601. To do. Next, one winning lottery table 212h corresponding to the output setting value obtained by referring to the output setting data 213e registered in the RAM 213 is selected (step S602).

  Then, it is checked whether the random number value acquired in step S601 belongs to any numerical range in the role lottery table 212h (step S603). If the random number value belongs to any numerical range (step S603: YES), the winning information of the winning combination is set in the internal lottery flag 213i (step S604). If the random number value does not belong to any numerical value range (step S603: NO), information on the loss is set in the internal lottery flag 213i (step S605). Then, the process returns to the game progress main process by the main program 212a.

  As described above, according to the slot machine 1 of the above-described embodiment, in the power-off process when the main switch 251 is turned off, the data contents of the program counter and other registers of the main control board 21 are stored in the stack area 213a of the RAM 213. In step S102, in the subsequent setting change process of the payout rate, the game conditions (variable data, state flag) at the time of power-off stored in the RAM 213 are retained in the stack area 213a. Restore the saved register contents (program counter, etc.). Therefore, the game can be resumed by reproducing and maintaining various conditions at the time of power-off after returning the setting of the payout rate. As a result, it is possible to make it impossible to artificially operate the game conditions after returning to the setting, and to prevent illegal acts such as morning.

  Further, in the setting change process of the payout rate, the checksum of the RAM 213 is calculated, and when the data does not match the value before the power interruption (step S502: NO), it is determined that the data error cannot be recovered, and the power supply In the throwing initialization process (S503), the storage area of the RAM 213 excluding the output setting data 213e is initialized (S301). By doing this, for example, even if the slot machine 1 is in a power-off state, even if an unauthorized person alters the stored contents of the RAM 213, the game conditions are completely initialized after the settings are restored, and the game resumes. It will be. Therefore, such an illegal act can be made meaningless and harmless, and the game after the setting return can be started normally and uniformly.

  Also, during the game, an untransmitted normal command or the like waiting in the transmission queue buffer 213c ′ for transmitting the normal command and data from the main control board 21 to the sub control board 33 is changed in the output rate setting change process. All are transmitted to the sub-control board 33 (steps S506 to S507). Therefore, in the game after returning the setting of the payout rate, it is possible to reliably avoid a problem such as a mismatch between the game content and the production content due to the loss of the normal command, data, and the like.

  Further, in the setting change process of the payout rate, the payout setting data is transmitted via a transmission mode (special command transmission mode) that is different from the clock interruption routine that is started at a predetermined cycle while the game of the slot machine 1 is in progress. Data such as 213e is transmitted to the sub-control board 33. As a result, even if the setting change device for the payout rate is activated during the game, the transmission queue buffer 213c ′ is not accessed when a special command or data is transmitted, and an untransmitted command waiting for this is sent. In addition, the data is retained without being destroyed. Therefore, it contributes to the complete recovery of the game after setting the payout rate, and does not cause problems such as a mismatch in the operating environment between the main control board 21 and the sub control board 33 in the game after the return of setting. Can do.

  The present invention can be applied not only to a slot machine but also to a general gaming machine that provides a game in which a gaming medium such as a medal or a pachinko ball is betted and the gaming medium is paid back based on a lottery result.
