Description

  The present invention relates to a gaming machine such as a pachinko gaming machine, and more particularly to a technique for controlling a program operation in the gaming machine.

  Conventionally, among the various ball game machines, a so-called first type pachinko game machine is used while changing a plurality of symbols in a display area such as a liquid crystal display provided substantially at the center of the game board. Display (hereinafter, such display is referred to as “symbol change” or “change display”). This gaming machine shifts to a special game called so-called jackpot where more prize balls can be obtained than a normal game when a combination of symbols when a plurality of rows of symbol variations are stopped becomes a specific mode. Known as a thing. The variation display of the symbols in the display area is not just a variation display of multiple symbols, but the time of variation display in a state where it is a big hit if one more symbols are aligned, as in the so-called reach variation screen. For example, it is designed to increase the player's expectation such as making it longer than usual. In addition, a variety of effects that enhance the player's expectation, such as notice effects and mission effects, are prepared. As a result of dramatic progress in complication and refinement of the effects and enlargement of the liquid crystal display, etc., it is caused by effect control. The processing load is increasing.

In recent years, ball game machines have become more complicated in controlling the progress of the game as a result of the increased freedom of game methods and contents. Due to this complexity, not only the processing load has increased, but the synchronism between the performance state and the game state has also become more severe, and the demand for high-speed processing has been increasing in order to strictly observe the operation timing. . Therefore, a method of executing a program stored in the ROM after expanding it in the RAM has been gradually adopted (for example, see Patent Document 1). Such an increase in operation load and an increase in demand for high-speed processing are not limited to ball game machines, and the same tendency tends to be applied to a spinning cylinder game machine in which liquid crystal displays are successively mounted.

  Since ROM is normally read-only and stored data is not rewritten, there is no concern that the stored data will be unexpectedly damaged or overwritten with different data, and data identity is always ensured. However, in the case of a method in which ROM data is read after being expanded into the RAM, the data on the RAM is unexpectedly damaged due to noise, or the storage state of the RAM is unexpected due to an extremely rare gaming state or illegal operation. If this happens, normal operation cannot be expected.

  The present invention has been made in view of these problems, and an object thereof is to provide a technique for optimizing a program operation in a gaming machine.

  In order to solve the above problems, a gaming machine according to an aspect of the present invention is a lottery for determining whether or not to shift to a special game that is more advantageous to the player than a normal game, triggered by a predetermined game operation. The lottery means for performing the game, the display device for displaying the variation for the result of the lottery, the display control unit for variably displaying the symbol on the display device, and the success or failure lottery can be shifted to a special game. As a result, the program data including a special game control means for executing a special game and a program for controlling a game or an effect for reading are displayed for reading. A stored nonvolatile storage device, a volatile storage device that temporarily stores at least part of the program data, a read speed higher than that of the nonvolatile storage device, and at least a small amount of program data Data writing means for reading a part from the nonvolatile storage device and writing it to the volatile storage device, and write destination data that is temporarily stored in the volatile storage device is data stored in the nonvolatile storage device In order to collate with the writing source data, the data monitoring means for collating the whole by repeatedly reading and collating the writing destination data and the writing source data for each predetermined unit, and the data mismatch in the collation by the data monitoring means When the result is, an emergency processing means for executing an emergency process predetermined as a process to be performed when a data mismatch occurs is provided.

  Here, the “nonvolatile storage device” is assumed to be a ROM (Read Only Memory) that can retain the stored contents even after the gaming machine is turned off, but a memory such as an EEPROM that can be rewritten by a predetermined method. It may be a device. The “volatile storage device” is assumed to be a RAM (Random Access Memory) that functions as a so-called work memory. However, the “volatile storage device” only needs to function as a work area capable of reading data at a higher speed than the “nonvolatile storage device”, and is not necessarily volatile. It is not intended to strictly ask whether or not there is. The “program for controlling the game or performance” may be a program in which operations directly related to game progress and player profit generation such as winning / failing lottery, symbol determination, symbol variation, etc., or display processing or machine It may be a program in which a stunning operation in a game such as an automatic operation is defined. Further, a program in which only one of these is defined may be a program, or a program in which both are defined. The “matching process” may be a process performed at any time while a main control program related to the game progress of the entire gaming machine is executed. That is, collation is performed little by little regardless of the execution timing of the data portion to be collated. Such processing may be continuously processed by using a free time of a CPU (Central Processing Unit) in which interrupt processing has not occurred. “Emergency process” may be a process of restarting the entire gaming machine by resetting or forcibly ending, etc., or data rewriting from a non-volatile storage device to a volatile storage device. The process which outputs the alert | report which shows that to the outside may be sufficient.

  In a conventional game machine program, there are few problems of execution speed and processing load. Therefore, a method of executing a program or data after loading the program or data from ROM to RAM has not been frequently used. According to this aspect, it is possible to perform an operation to warn or correct data corruption or data inconsistency on the RAM, which is a concern when it is executed after being loaded into the RAM, as planned according to the program on the ROM. Operation can be ensured. Further, since data collation can be performed for each small data unit, an increase in processing load for collation can be suppressed, and data safety can be efficiently ensured, for example, processing using the CPU idle time can be performed.

  The data monitoring means may process the collation during execution of the main loop of the program while the program for controlling the game or performance is executed. As a result, while the main control program related to the game progress of the entire gaming machine is executed, the collation is continuously processed using the free time of the CPU in which no interrupt processing occurs. Therefore, data consistency on the RAM can be ensured without causing an excessive load, and the operation as planned according to the program on the ROM can be efficiently ensured.

  The data monitoring means may set a specific data portion that is predetermined as data that does not cause a fatal malfunction in the game or performance even if data mismatch occurs between the write destination data and the write source data as a target of collation. Here, the “data that does not cause a fatal failure” is a range that does not adversely affect the progress of the game or the profit of the player even if the display timing is shifted or delayed in, for example, stunning display processing. This is the process. According to this aspect, it is sufficient to collate only a necessary part of the program data written in the RAM, and data consistency can be efficiently ensured without generating an unnecessary processing load.

  The emergency processing means may re-execute reading from the nonvolatile storage device and writing to the volatile storage device by restarting the gaming machine as emergency processing. When a data mismatch occurs, simply rewriting data from the nonvolatile storage device to the volatile storage device may induce another data mismatch depending on the status of various parameters. Is also possible. According to this aspect, by restarting the game machine by a method such as resetting or forcibly ending the game machine, it is possible to re-execute the initialization operation similar to that at the time of normal power-on and ensure data consistency. .

  It should be noted that any combination of the above-described constituent elements, or the constituent elements and expressions of the present invention may be mutually replaced between methods, apparatuses, systems, computer programs, recording media storing computer programs, data structures, etc. This is effective as an embodiment of the present invention.

  According to the gaming machine of the present invention, it is possible to provide a technique for optimizing the program operation.

The upper ball tray 15 has a mechanism for storing game balls, sending out the game balls to the launch rail, and extracting the game balls to the lower ball tray 16. The lower ball tray 16 has a mechanism for storing and extracting game balls. A speaker 18 is provided between the upper ball tray 15 and the lower ball tray 16, and a sound effect corresponding to the gaming state is output.

  The game board 50 has an out port 58, a special symbol display device 61, an effect display device 60, and a start winning port (hereinafter referred to as “start port”) 62 on a game area 52 defined by the outer rail 54 and the inner rail 56. , A center ornament 64, a grand prize opening 66, an operation opening 68, and a general prize opening 72. Furthermore, in the game area 52, a plurality of mechanisms such as a game nail and a windmill (not shown) are installed. The start port 62 includes a start winning detection device 74 for detecting the entrance of a game ball and a normal electric accessory solenoid 76 for expanding the expanding mechanism of the start port 62. When the expansion mechanism of the start port 62 is expanded, the opening width of the start port 62 is expanded and the ease of entering the ball is improved. The start winning detection device 74 is a sensor that detects the entry of a game ball into the start port 62, and generates start win information indicating the winning at the time of entering. The general winning opening 72 includes a general winning detecting device 73 for detecting the entering of a game ball. The general winning detection device 73 is a sensor that detects the entry of a game ball into the general winning opening 72, and generates general winning information indicating the winning at the time of winning. The special winning opening 66 includes a winning detection device 78 for detecting the entry of a game ball and a special winning opening solenoid 80 for expanding the special winning opening 66. The winning detection device 78 is a sensor that detects the entry of a game ball into the big winning opening 66, and generates big winning opening winning information indicating the winning at the time of winning.

  The big winning opening 66 is a horizontal rectangular winning opening that is opened as a “big hit” when the special symbol 192 stops in a predetermined manner. The big winning opening 66 is provided above the out opening 58 and the like. The winning detection device 78 of the big winning opening 66 includes a sensor that detects the passage of a game ball.

  The special symbol display device 61 provided on the left side of the game area 52 and the effect display device 60 provided in the approximate center of the game area 52 have a variation of the special symbol 192 on each screen and a decoration linked to the special symbol 192. The variation of the effect image including the symbol 190 is displayed (hereinafter, such display is referred to as “symbol variation” or “variation display”). Here, the special symbol 192 is a symbol corresponding to the result of the lottery performed when the game ball is dropped into the start port 62, and the symbol mode when the change display is stopped is determined to be the winning symbol. When the symbol is a symbol, the timing at which the stop symbol is displayed is the jackpot occurrence timing. The special symbol display device 61 is display means composed of, for example, 7 segment LEDs. The effect display device 60 is a liquid crystal display that variably displays the decorative symbol 190 in a manner interlocked with the variation display of the special symbol 192. The decorative symbol 190 is a symbol for visually rendering the lottery result display indicated by the special symbol 192. The effect display device 60 displays, as the decorative symbol 190, for example, a plurality of rows of moving images of symbol variation simulating a slot machine game in the central area of the screen. The effect display device 60 is constituted by a liquid crystal display in this embodiment, but may be constituted by a mechanical rotating device such as a drum or other display means such as an LED. Since the special symbol 192 does not necessarily have a role of production, in this embodiment, the special symbol 192 is displayed in an inconspicuous size on the special symbol display device 61 at the lower left of the production display device 60. In the case of adopting a technique in which a decorative role is not displayed and a decorative symbol is not displayed, the special symbol may be displayed on a liquid crystal display such as the effect display device 60. The operation port 68 is provided at the left side position of the game board 50. The operation port 68 includes a passage detection device 69. The passage detection device 69 is a sensor that detects the passage of the game ball to the operation port 68, and generates passage information indicating the passage at the time of passage. The passage of the game ball to the operation port 68 triggers an open lottery for determining whether or not to expand the expansion mechanism of the start port 62. When the game ball passes through the operation port 68, a normal symbol, which is a symbol indicating the result of the open lottery, is variably displayed on the normal symbol display device 59. The normal symbol display device 59 is provided on the lower right side of the effect display device 60. When the normal symbol variation display is stopped after a predetermined time has elapsed, the start port 62 is normally expanded for a predetermined time with a probability of about 50% to 80%.

  A center ornament 64 is provided around the effect display device 60. The center decoration 64 has functions such as a flow path of the game ball, protection of the special symbol display device 61 and the effect display device 60, and decoration. A lottery hold lamp 20 is provided below the effect display device 60, and an operation hold lamp 22 is provided below the normal symbol display device 59 at the lower right of the game area 52, which is a symmetrical position. . The lottery hold lamp 20 is composed of four lamps, and displays the number of lottery holds depending on the number of lights. The number of lottery holds is the number of lottery results won to the start port 62 during symbol variation or special game, and indicates the number of winning balls for which symbol variation has not yet been executed. The operation hold lamp 22 is also composed of four lamps, and displays the number of hold of normal symbol fluctuations depending on the number of lights. The number of normal symbol fluctuations held is the number of game balls that have passed through the operation port 68 during the fluctuation of the normal symbol, and indicates the number of normal symbol lotteries for which the fluctuation of the normal symbol has not yet been executed. Furthermore, game effect lamps 90 are respectively provided above and below the effect display device 60. The operation button 82 is a button that the player operates to input a predetermined instruction to the gaming machine. The operation button 82 is provided on the outer wall surface near the upper ball tray 15.

  When the player turns the launch handle 17 by hand, the game balls stored in the upper ball tray 15 are guided one by one to the inner rail 56 and the outer rail 54 with a strength corresponding to the turning angle, thereby playing the game area. To 52. When the player fixes the rotation position of the firing handle 17 by hand, the game ball is repeatedly fired at regular time intervals. The game ball launched to the upper part of the game area 52 falls in a direction according to the way of hitting while hitting a plurality of game nails and windmills. When a game ball is dropped into each of the general winning port 72, the start port 62, and the big winning port 66, the winning ball corresponding to the type of the winning port is paid out to the upper ball plate 15 or the lower ball plate 16. A game ball dropped into each winning hole such as the general winning hole 72 is processed as a safe ball, and a game ball dropped into the out hole 58 is processed as an out ball. Each winning opening includes a gate type through which a game ball passes. In this application, “incoming”, “entering”, and “winning” include “passing”.

  When the game ball falls into the start port 62, the special symbol 192 and the decorative symbol 190 are variably displayed on the special symbol display device 61 and the effect display device 60. The variable display of the special symbol 192 and the decorative symbol 190 is stopped after the elapse of the display time determined prior to the display. When the special symbol 192 and the decorative symbol 190 at the time of the stop are symbols indicating a big hit, the game shifts to a special game that is more advantageous to the player than the normal game, and the opening / closing operation of the big prize opening 66 is started. At this time, the decorative pattern 190 simulating the game of the slot machine takes a display mode in which the three patterns are matched. In the special game, the grand prize winning slot 66 is temporarily closed after being opened for about 30 seconds or after 9 or more game balls are dropped. Such opening / closing of the big prize opening 66 is repeated a predetermined number of times, for example, 15 times.

  In the normal game after the end of the special game, a variable time shortening game (hereinafter referred to as “time reduction” as appropriate) that is one of the specific games is started. In the variation time shortening game, the variation time of the special symbol and the decorative symbol is shortened from the normal time. The variation time of the special symbol and the decorative symbol is returned to the original variation time after the variation display of a predetermined variation number is performed. When a special game occurs and the winning stop pattern at that time is in a specific mode, a probability variation game (hereinafter referred to as “probability change” as appropriate) that is one of the specific games after the special game ends Be started. In the probability variation game, a lottery with a higher win probability than the normal probability state is performed, and a new special game is generated relatively early.

  FIG. 2 shows a basic structure on the back side of the pachinko gaming machine. The power switch 40 is a switch for turning on / off the power of the pachinko gaming machine 10. The main board 102 controls the overall operation of the pachinko gaming machine 10 and processes all game operations such as a lottery when a winning is made to the start port 62. The sub-board 104 includes a liquid crystal unit 42 and controls display contents on the effect display device 60, operations of the plurality of movable objects 140, and lighting of the game effect lamp 90. And the lighting of the movable accessory 140 and the game effect lamp 90 is activated along with the progress of the production. The main board 102 and the sub board 104 constitute a game control device 100. The set base 39 includes a prize ball tank 44, a flow path for prize balls, a payout unit 43 for delivering prize balls. The payout unit 43 pays out the game balls supplied from the winning ball tank 44 to the upper ball tray 15 in accordance with winning in each winning opening. The payout control board 45 controls the payout operation by the payout unit 43. The launching device 46 launches the stored balls in the upper ball tray 15 to the game area 52 one by one. The launch control board 47 controls the launch operation of the launch device 46. The power supply unit 48 supplies power to each part of the pachinko gaming machine 10.

  FIG. 3 is a block diagram showing main hardware configurations of the main board 102 and the sub board 104. The main board 102 includes a first CPU 200 that is a central processing unit, a first RAM 204 that is a volatile storage device as a temporary storage device, and a first ROM 208 that is a non-volatile storage device. Data is transferred via 210. The first ROM 208 stores program data including a program and data for the main board 102 for reading. The program is a program in which operations and controls that are directly related to the game progress and the player's profit are defined, and may be composed of a plurality of program modules. For example, a program for controlling the success / failure lottery, a program for controlling symbol variation, and the like are stored.

  The program data may be stored in the first ROM 208 in a compressed state. The program data stored in the first ROM 208 is read via the first input / output interface 206 and developed. At least a part of the expanded program data is written to the first RAM 204 and temporarily stored. Thereafter, the data is read from the first RAM 204 and executed by the first CPU 200. Data reading and writing in the first RAM 204 are processed by the first memory controller 202. The data reading speed from the first RAM 204 is higher than the data reading speed from the first ROM 208. In particular, in a program that requires high-speed processing, it is preferable that the program is written in the first RAM 204 in advance and then read from the first RAM 204 and executed, rather than directly read from the first ROM 208 and executed.

  The first ROM 208 further stores a checksum of the program data stored therein. This checksum will be described in detail later. Which part of the program data stored in the first ROM 208 is written to the first RAM 204 is determined according to the characteristics of the data part. For example, most of the program data is written in the first RAM 204, while a program for monitoring or checking data consistency, which will be described later, is read from the first ROM 208 and executed instead of the first RAM 204. This is because the program data itself cannot be monitored or inspected. Further, in order to check the data consistency, a data portion that is so large that an excessive load is generated and the test cannot be performed is directly read from the first ROM 208 so that the data consistency test is not required. The execution result by the first CPU 200 is output to the external configuration such as the special symbol display device 61 through the first input / output interface 206 and also to the sub-board 104.

  The sub-board 104 also includes a drawing processing unit 230 in addition to the second CPU 220 that is a central processing unit, a second RAM 224 that is a volatile storage device as a temporary storage device, and a second ROM 228 that is a nonvolatile storage device. Data is transferred between these components via the second bus 232. The second ROM 228 stores program data including a program and data for the sub-board 104 for reading. This program is a program in which operations and controls mainly related to game effects are defined, and may be composed of a plurality of program modules. For example, a program for controlling the variable display of decorative symbols is stored. The second ROM 228 further stores a checksum of program data stored therein.

  The basic operations of the second CPU 220, the second RAM 224, and the second ROM 228 are the same as those of the first CPU 200, the first RAM 204, and the first ROM 208 in the main board 102. That is, at least a part of the program data stored in the second ROM 228 is written and temporarily stored in the second ROM 228, and is read from the second ROM 228 and executed. Data reading and writing of the second RAM 224 are processed by the second memory controller 222. Data reading from the second ROM 228 is processed via the second input / output interface 226. The drawing processing unit 230 processes image display on the effect display device 60. A drawing processing command to the drawing processing unit 230 is sent from the second CPU 220 via the second input / output interface 226. The other execution results by the second CPU 220 are output to an external configuration such as the game effect lamp 90 via the second input / output interface 226.

  Note that, according to this figure, the main board 102 and the sub board 104 are shown to have almost the same hardware configuration, but the actual specification is that the memory capacity and CPU capacity depend on the processing contents and processing load. The clock frequency may be different. In particular, since display control on the effect display device 60 is processed in the sub-board 104, it is assumed that the processing load and the data size are relatively larger than the main board 102. In the drawing, the first CPU 200, the first RAM 204, and the first memory controller 202 are configured as separate elements, and the second CPU 220, the second RAM 224, and the second memory controller 222 are configured as separate elements. As a modification, the first RAM 204 and the first memory controller 202 may be built in the first CPU 200, and the second RAM 224 and the second memory controller 222 may be built in the second CPU 220.

  FIG. 4 shows functional blocks of the pachinko gaming machine 10 in the present embodiment. In the pachinko gaming machine 10, the game control device 100 includes a start port 62, a big winning port 66, a general winning port 72, an operating port 68, a special symbol display device 61, an effect display device 60, a normal symbol display device 59, and operation buttons 82. The speaker 18, the game effect lamp 90, and the movable accessory 140 are electrically connected to each other, and can transmit and receive various control signals. The game control apparatus 100 controls not only the basic operation of the game but also the staging operations such as the symbol variation display, the movable accessory 140, and the electric decoration. The game control device 100 is configured in such a manner that functions are shared between a main board 102 that controls the overall operation of the pachinko gaming machine 10 including basic operations of the game, and a sub board 104 that controls design effects and the like. In this figure, the main board 102 and the sub board 104 will be described by dividing into blocks in units of functions regardless of hardware units or software units.

  In the present embodiment, the main board 102 is a ball determination unit 110, a winning / failing lottery unit 112, a symbol determination unit 114, a hold control unit 116, a main display control unit 118, a special game control unit 120, a specific game execution unit 122, and an opening / closing control. Means 124 are provided. The sub-board 104 in this embodiment includes a pattern storage unit 130, an effect determination unit 132, an effect display control unit 134, and an accessory control unit 136. Each functional block included in the main board 102 may be configured such that any one of the functional blocks is mounted on the sub board 104 instead of the main board 102. Similarly, each functional block included in the sub-board 104 may be configured such that any one of them is mounted on the main board 102 instead of the sub-board 104.

  The entrance determination means 110 determines whether or not a game ball has entered each winning opening. When receiving the start winning information, the winning determination means 110 determines that the game ball has won the start opening 62, and when receiving the big winning opening winning information, determines that the game ball has won the big winning opening 66, and the general winning is obtained. When the information is received, it is determined that the game ball has won the general winning opening 72. When receiving the passage information, the ball entering determination unit 110 determines that the game ball has passed through the operation port 68.

  The success / failure lottery means 112 accepts a random number value to determine whether or not to shift to a special game that is more advantageous to the player than the normal game when the game ball enters the start port 62. Get as a value. For example, the success / failure lottery value is acquired from a value range from “0” to “65535”. The “random number” in the present application may not be a mathematically generated random number, but may be a pseudo-random number generated by a hardware random number, a software random number, or the like. The success / failure lottery means 112 holds a plurality of success / failure tables to be referred to in the success / failure determination. In the plurality of success / failure tables, the determination result of winning or losing is associated with the winning / losing lottery value, and the success / failure probability is determined according to the associated winning range setting. The success / failure lottery means 112 refers to a success / failure table for determination of success / failure based on a normal probability in normal times, and refers to a success / failure table in which the winning probability is higher than the normal probability when the probability changes. The success / failure lottery means 112 refers to any of the plurality of success / failure tables and determines whether or not the success / failure lottery value is a win. The determination result by the success / failure lottery means 112 is variably displayed in a special symbol form on the special symbol display device 61. In addition, a decorative symbol that shows the determination result by the success / failure lottery means 112 in an effect manner is variably displayed on the effect display device 60.

  The symbol determination unit 114 determines the stop symbol and the variation pattern of the special symbol to be displayed on the special symbol display device 61 according to the lottery result by the success / failure lottery unit 112. Moreover, the symbol determination means 114 determines the stop symbol of the normal symbol displayed on the normal symbol display device 59 by lottery. The stop symbol is a symbol to be displayed at the end of symbol variation. The symbol determination means 114 holds a symbol range table to be referred to in order to determine a special symbol or a normal symbol stop symbol, or a pattern determination table to be referred to in order to determine a variation pattern.

  The symbol determination means 114 acquires a symbol determination lottery value for determining a special symbol, and determines the stop symbol of the special symbol according to the determination result of the success / failure lottery means 112 and the symbol determination lottery value. The symbol determination unit 114 selects one of a plurality of variation patterns in accordance with the determination result of the success / failure lottery unit 112. The symbol determination unit 114 sends data indicating the determined stop symbol and variation pattern to the main display control unit 118 and the effect determination unit 132.

  The symbol determination means 114 stores a plurality of types of variation patterns in which variation modes from the variation start to the stop when the special symbol is variably displayed are defined. Multiple types of variation patterns have various variation times. That is, for each variation pattern, a variation display time is defined for each pattern as an end condition of the symbol variation, and the variation of the special symbol is stopped when the variation display time elapses.

  The symbol determining means 114 acquires a lottery random number for determining a normal symbol when the game ball passes through the operation port 68, and determines a stop symbol of the normal symbol according to the lottery random number. When the stop symbol of the normal symbol is a specific symbol, the opening / closing control means 124 expands the normal electric accessory at the start port 62 for a predetermined time.

  The hold control means 116 holds the winning / losing lottery value acquired by the winning / failing lottery means 112 as a holding ball. The success / failure lottery value is accumulated until the number of holds reaches a predetermined upper limit. The upper limit of the number of holds is 4.

  The main display control means 118 causes the special symbol display device 61 to display the lottery result by the success / failure lottery means 112 as a special symbol variation display according to the variation pattern determined by the symbol determination unit 114. The main display control means 118 transmits the change start command and the change stop command to the effect display control means 134 at the timing of starting and stopping the change display of the special symbol, so that the main display control means 118 and the effect display are displayed. The fluctuation display by the control means 134 is synchronized and interlocked. The main display control means 118 displays the normal symbol variation on the normal symbol display device 59.

  The special game control means 120 controls the execution process of the special game when the result of the lottery determination by the success / failure lottery means 112 is a win. The special game is a game in which the opening / closing operation of the special winning opening 66 is continuously continued a plurality of times, and is constituted by one or a plurality of unit games with one opening / closing as a unit. The unit game is repeated up to 15 times, for example, and the grand prize opening 66 is opened for about 30 seconds in one unit game. If the number of continuations of the unit game has not reached the upper limit number, the special game control means 120 starts the next unit game after the end of the current unit game. When the upper limit number of unit games is exhausted, the special game is terminated.

  The specific game execution means 122 executes control for shifting the game state from the normal state to the specific game state, and control for returning the specific game state to the normal state. The specific game in this embodiment has a probability change in which the winning probability of the winning / failing lottery is switched from a normal probability state to a high probability state and a short time in which the symbol variation time is switched from a normal time to a short time.

  The specific game executing means 122 shifts the gaming state after the special game to the probability changing state when the winning / failing lottery value is a value to be shifted to the probability changing state. The probability variation state is continued until the next jackpot is generated in principle, and during that time, the probability of the hit determination by the success / failure lottery means 112 is maintained at a high value. In addition, the specific game executing means 122 shifts the game state to the time-shortened state after the special game regardless of the winning lottery value. The short time is continued until the number of changes in the special symbol after the special game reaches a predetermined number, for example, 100 times.

  The opening / closing control means 124 controls the opening / closing of the ordinary electric accessory at the start opening 62 and the special winning opening 66. When the normal symbol is stopped at a specific symbol, the opening / closing control unit 124 sends an opening instruction to the ordinary electric accessory solenoid 76 to open the start port 62. Further, the opening / closing control means 124 sends an opening instruction to the special winning opening solenoid 80 during the special game, and opens the special winning opening 66.

  The first data writing means 150 reads at least part of the program data for the main board 102 from the first ROM 208, writes it into the first RAM 204, and temporarily stores it. The program data temporarily stored in the first RAM 204 includes, for example, a ball entering determination unit 110, a winning / failing lottery unit 112, a symbol determination unit 114, a hold control unit 116, a main display control unit 118, a special game control unit 120, and a specific game execution unit 122. This is a program for realizing each function of the opening / closing control means 124.

  The first data monitoring unit 152 collates write destination data that is data temporarily stored in the first RAM 204 with write source data that is data stored in the first ROM 208. The write destination data and the write source data are read and collated in units of a predetermined unit, for example, 1 byte. The whole collation is performed by repeating the collation process. The function program module for collation by the first data monitoring unit 152 is not directly written to the first RAM 204 and read from the first RAM 204 but is directly read from the first ROM 208 and executed. The collation process is executed little by little as a process included in the main loop in the main program executed by the first CPU 200. Therefore, processing is continuously repeated using the CPU idle time without interrupt processing. As a result, the collation is repeated regardless of the execution timing of the program, and data consistency is always ensured as a whole.

  The first data monitoring unit 152 selects a specific data portion that is predetermined as data that does not cause a fatal malfunction in the game or performance even if a data mismatch occurs in the write destination data and the write source data as a target of collation. To do. For example, a control program and data portion that does not directly affect the winning / losing lottery or the appearance of balls on the main board 102 are defined in advance as the specific data portion, and are subject to collation by the first data monitoring means 152.

  When at least a part of the write destination data is read and executed, the first data checking means 154 checks the write source data immediately before it and writes it on condition that the data match is confirmed. Allow execution of the destination data. As a verification method, a method of comparing checksums is used. In other words, the first data checking means 154 calculates a checksum for the program portion of the write destination data for which the execution instruction is called, triggered by the call. The first data checking means 154 reads the checksum of the corresponding part in the writing source data from the first ROM 208 and collates it with the calculated checksum of the writing destination data.

  The first data checking means 154 uses a specific data portion, which is predetermined as data that causes a fatal malfunction in a game or performance when a data mismatch occurs in the write destination data and the write source data, as a target of verification. To do. Many of the functions included in the main board 102 have a direct influence on the lottery and the lottery. Therefore, the program and data portions related to many functions are defined in advance as specific data portions, and the first data checking means 154 Targeted for verification. If the data consistency is not confirmed, the execution of the data portion is not permitted, and thus the execution safety of a portion that may cause a fatal malfunction is ensured.

  Here, the collation by the first data monitoring means 152 and the collation by the first data inspection means 154 have the following differences. That is, the collation by the first data monitoring unit 152 is performed little by little regardless of the execution timing of the data portion to be collated, whereas the collation by the first data inspection unit 154 is performed immediately before the execution of the data portion to be collated. The verification timing is different in that it is made. In other words, different verification methods are adopted depending on whether or not the influence on the game when the data mismatch occurs is fatal. The collation by the first data monitoring means 152 is compared for each small data unit in one collation process, whereas the collation by the first data inspection means 154 is such that the data portion to be collated is once as a whole. It is different in that it is compared. Because of these differences, the collation by the first data inspecting means 154 employs collation by comparing checksums. In this case, the checksum of the write source data can be calculated in advance and stored in the first ROM 208, so there is no need to calculate it again, and only the checksum is calculated for the write destination data rather than checking all the data. Since the load on the first CPU 200 is smaller, it is possible to collate more easily. However, if the size of the data is so large that an excessive processing load is generated and the high-speed processing is hindered to calculate the checksum, it is not expanded to the RAM in order to prioritize the safety of execution. It is determined that the program is read directly from the ROM and executed.

  The first emergency processing unit 156 is an emergency that is determined in advance as a process to be performed when a data mismatch occurs when a data mismatch result is obtained in the collation by the first data monitoring unit 152 or the first data checking unit 154. Execute the process. In this embodiment, three types of processing are prepared as emergency processing. The first is error notification to the outside, the second is data rewriting to the first RAM 204, and the third is restart of the entire pachinko gaming machine 10. The error notification is a process of notifying the outside that a data mismatch has occurred using a lamp, a signal, or the like, and may include a process of temporarily stopping the operation of the pachinko gaming machine 10. The error notification is one of emergency processes performed when a data mismatch result is output to either the first data monitoring unit 152 or the first data checking unit 154. Data rewriting is a process of reading data from the first ROM 208 and rewriting the data in the first RAM 204. Data rewriting is one of emergency processes performed when the first data checking means 154 produces a data mismatch result. The restart is a process of causing the initialization operation to be executed and the data in the first ROM 208 to be written again into the first RAM 204 by returning to the initial state when the power is turned on by resetting or forcibly terminating the pachinko gaming machine 10. . The restart is one of emergency processes performed when a data mismatch result is output to either the first data monitoring unit 152 or the first data checking unit 154. Which emergency process is used differs depending on the classification of the data portion where the data mismatch occurred, and is determined in advance for each classification. For example, regarding a data portion where a data mismatch does not have a fatal influence, even if a data mismatch occurs, it may be classified to notify the outside, or a data portion that has a fatal influence may be classified into the first RAM 204. The classification may be rewriting or restarting. For example, a data portion that cannot be restored to a normal state due to a mismatch between a gaming state and various parameter states simply by rewriting may be classified as restarted.

  The second data writing means 160 reads at least a part of the program data for the sub board 104 from the second ROM 228, writes it into the second RAM 224, and temporarily stores it. The program data temporarily stored in the second RAM 224 is, for example, a program for realizing the functions of the pattern storage unit 130, the effect determination unit 132, the effect display control unit 134, and the accessory control unit 136.

  The second data monitoring unit 162 collates the write destination data that is data temporarily stored in the second RAM 224 with the write source data that is data stored in the second ROM 228. The write destination data and the write source data are read and collated in units of a predetermined unit, for example, 1 byte. By repeating this collation process, the entire collation is performed. The function program module for collation by the second data monitoring unit 162 is not directly written to the second RAM 224 and read from the second RAM 224 but is directly read from the second ROM 228 and executed. The collation process is executed little by little as a process included in the main loop in the main program executed by the second CPU 220. Therefore, processing is continuously repeated using the CPU idle time without interrupt processing. Thereby, since collation is continued regardless of the execution timing of the program, data consistency is ensured.

  The second data monitoring unit 162 uses a specific data portion that is predetermined as data that does not cause a fatal malfunction in the game or performance even if there is a data mismatch in the write destination data and the write source data as a target of verification. To do. For example, an effect control program and data portion that does not directly affect the operations related to the player's interest such as winning / failing lottery and appearance in the sub-board 104 are defined in advance as the specific data portion, and the second data monitoring means 162 It is the target of collation by. As the effect control that does not directly affect the operation related to the player's profit such as winning / failing lottery or appearance, for example, the control of the game effect lamp 90 by the effect display control means 134 or the effect determining means 132 lottery the variation pattern For example, a random number update process for the purpose.

  When at least a part of the write destination data is read and executed, the second data checking means 164 collates with the write source data immediately before it and writes it on condition that the data match is confirmed. Allow execution of the destination data. As a verification method, a method of comparing checksums as in the first data checking means 154 is used. In other words, the second data checking means 164 calculates a checksum for the program portion of the write destination data for which the execution instruction is called, triggered by the call. The second data checking means 164 reads the checksum of the corresponding part in the write source data from the second ROM 228 and compares it with the calculated checksum of the write destination data.

  The second data checking means 164 uses a specific data portion, which is predetermined as data that causes a fatal malfunction in the game or performance when the data mismatch occurs in the write destination data and the write source data, as a target of verification. To do. Of the functions included in the sub-board 104, for example, data of a program that requires strictness in operation timing, such as symbol variation control, is defined in advance as a specific data portion, and is subject to verification by the second data inspection unit 164. Is done. In addition, even if strictness is not always required for the operation timing, there is a portion that may cause a physical failure if operation malfunctions, such as a control program for a motor that drives a stunning movable accessory 140. The second data inspection unit 164 can be a target for collation.

  The difference between the collation by the second data monitoring unit 162 and the collation by the second data inspection unit 164 is the same as the difference between the collation by the first data monitoring unit 152 and the collation by the first data inspection unit 154.

  The second emergency processing unit 166 is an emergency that is determined in advance as a process to be performed when a data mismatch occurs when a data mismatch result is obtained in the collation by the second data monitoring unit 162 or the second data checking unit 164. Execute the process. Similarly to the emergency processing in the first emergency processing means 156, this emergency processing is also provided with error notification to the outside, data rewriting to the second RAM 224, and restart of the entire pachinko gaming machine 10. Which emergency process is used differs depending on the classification of the data portion where the data mismatch occurred, and is determined in advance for each classification.

  The pattern storage unit 130 holds a plurality of variation pattern data in which a variation process from variation start to stop in variation display is defined as a variation pattern of the effect image including the decorative design. The fluctuation pattern displays a pattern for displaying a normal out symbol, a pattern for displaying a symbol out of reach after reaching a big win if one more symbols are aligned, and a jackpot symbol through a reach state. When the pattern is included. In particular, the pattern that passes through the reach state includes patterns having various fluctuation times. Each variation pattern has a variation time for each pattern as an end condition of the symbol variation, and the symbol variation is stopped when the variation time elapses. The effect determining means 132 selects the variation pattern of the effect image having the same variation time as that of the special symbol according to the variation pattern of the special symbol.

  The effect determining means 132 determines the combination of the stop symbols of the decorative symbols and their arrangement and variation pattern according to the result of the lottery by the success / failure lottery means 112, according to the stop symbol of the special symbol and the variation pattern of the special symbol. The effect determining unit 132 holds a symbol range table to be referred to in order to determine a stop symbol of a decorative symbol and a pattern table to be referred to in order to determine a variation pattern.

  The stop symbol of the decorative symbol is formed as a combination of three symbols. For example, when the determination result by the success / failure lottery means 112 indicates a shift to a special game, three symbols such as “777” and “111” are arranged. A combination is selected. In this case, it is preferable that the same numbers as the special symbols are selected as the numbers arranged as the decorative symbols. For example, when the special symbol is “3”, the decorative symbol is “333”. In the case where the determination result by the success / failure lottery means 112 indicates that the game does not shift to the special game, a combination that does not have three symbols such as “312” and “946” is selected. However, if the determination result is that the game does not shift to a special game, and a variation pattern of a special symbol indicating a loss with reach is selected, only one such as “191” or “727” is selected. Select a combination that does not have the same pattern. The effect determining unit 132 sends information about the stop symbol of the decorative symbol and the variation pattern of the effect image to the effect display control unit 134.

  The effect display control means 134 displays the effect image on the effect display device 60 in accordance with the selected variation pattern data as a result of the success / failure lottery by the success / failure lottery means 112. The effect display control means 134 further controls effect processing such as lighting and extinguishing of the game effect lamp 90 and sound output from the speaker 18.

  In accordance with the instruction received from the effect display control means 134, the accessory control means 136 causes the movable accessory 140 to act in an effect manner in accordance with the effect contents in the effect display device 60 and the blinking process of the game effect lamp 90.

  FIG. 5 is a flowchart showing a basic operation process in the pachinko gaming machine. First, processing is performed when a game ball has won the start port 62, the general winning port 72, the big winning port 66, or when the game ball has passed through the operation port 68 (S10). (N in S12), control processing for normal games such as winning / failing lottery is executed (S14), and if a special game is in progress (Y in S12), control processing for special game is executed (S16), from S10 to S16 In this process, prize ball payout according to various winnings is processed (S18), and a data monitoring process is executed (S20).

  FIG. 6 is a flowchart showing in detail the normal game control process of S14 in FIG. In the normal game control process, if the winning / losing lottery value is on hold (Y in S30) and the symbol variation is not being displayed (N in S32), the winning / losing lottery means 112 executes the determining process. (S34). In accordance with the determination result, the main display control means 118 starts changing display, transmits a change start command to the effect display control means 134, and the effect display control means 134 that receives the command displays the effect image according to the change pattern data. The fluctuation display is started (S36). If the winning or failing lottery value is not held in S30 (N in S30), the processing from S32 to S36 is skipped, and if the symbol variation is being displayed in S32 (Y in S32), S34 and S36 Is skipped. Subsequently, if the symbol variation display has already started (Y in S38), the symbol variation display process is executed (S40). If the symbol variation display has not started (N in S38), S40 is skipped. .

  FIG. 7 is a flowchart showing in detail the success / failure determination process of S34 in FIG. First, the success / failure lottery means 112 reads the success / failure lottery value (S42), and determines the success or failure based on the success / failure lottery value (S44). The symbol determining means 114 determines a stop symbol of the special symbol based on the determination result (S46), and selects a variation pattern of the special symbol (S48). The effect determination means 132 determines the stop symbol combination of the decorative symbols based on the determination result and the special symbol (S50), and selects the variation pattern of the decorative symbol according to the variation pattern of the special symbol (S52).

  FIG. 8 is a flowchart showing in detail S16 in FIG. First, if the big prize opening 66 has not been opened (N in S70), the production display control means 134 starts the special game production process (S72), and the open / close control means 124 opens the special prize opening 66 (S74). ). If the big winning opening 66 has been opened, S72 and S74 are skipped (Y in S70). When the predetermined opening time has elapsed since the grand prize opening 66 was opened (Y in S76), or the opening time has not elapsed (N in S76), there are nine or more game balls to the big winning opening 66 When the player has entered the ball (Y in S78), the opening / closing control means 124 closes the special winning opening 66 (S80). If the opening time has not elapsed (N in S76) and the number of balls entered into the grand prize winning opening 66 has not reached nine or more (N in S78), the processing after S80 is skipped and the flow of S16 Exit.

  If the number of rounds of the unit game has reached 15 after closing the special winning opening 66 in S80 (Y in S82), the effect display control means 134 ends the effect processing of the special game (S84), and the special game control means 120 ends the special game (S86). If the number of rounds has not reached 15 (N in S82), 1 is added to the number of rounds and the flow of S16 is terminated (S90).

  FIG. 9 is a flowchart showing in detail the data monitoring process of S20 in FIG. Hereinafter, the first data monitoring unit 152 will be described as an example, but the same processing is performed with respect to the collation by the second data monitoring unit 162, and thus the description is omitted. The first data monitoring means 152 reads the address of the data part that was the previous collation target (S100). In the case of the first process after power-on, since there is no “previous” process, the first address to be verified by the first data monitoring unit 152 is read. Based on the read address, the address of the data portion to be collated this time is calculated (S102). In this embodiment, since each byte is collated, in principle, the current address can be obtained by adding 1 byte to the previous address. However, if it is not a data portion to be collated by the first data monitoring means 152, the address is skipped. Based on the calculated address, one byte of the data portion to be collated this time is read from the first RAM 204 (S104), and one byte of the data portion to be collated this time is also read from the first ROM 208 (S106). When the read data parts are compared with each other and the data do not match (N in S108), if the data part is an error notification target (Y in S110), a notification that the data is inconsistent is issued. If it is not the target of error notification (S112), S112 is skipped (N in S110). Also, if the part where the data does not match is the target of restart (Y of S114), the pachinko gaming machine 10 is restarted by resetting or forcibly terminating (S116), and if it is not the target of restart, S116 is skipped (N in S114). If the data match in the data comparison in S108, the processing from S110 to S116 is skipped (Y in S108). When it is determined in S108 that the data does not match, both the error notification in S112 and the restart in S116 may be executed. On the other hand, it is assumed that emergency processing is assigned so that at least one of them is always executed.

  FIG. 10 is a flowchart showing details of an interrupt process related to a data inspection process that occurs when various functions are called in each step of FIGS. Hereinafter, the first data inspection unit 154 will be described as an example, but the same processing is performed with respect to the collation by the second data inspection unit 164, and thus the description thereof is omitted. The first data checking unit 154 calculates a checksum for the data portion of the write destination data to be verified (S150), and reads the checksum of the write source data corresponding to the data portion from the first ROM 208 (S152). . The checksums of the write destination data and the write source data are compared, and if they match, the processing after S156 is skipped (Y in S154), and the execution of the data portion is permitted (S168). If the checksums do not match (N in S154) and the data portion is the target of error notification (Y in S156), a notification that the data does not match is executed (S158). If it is not a notification target, S158 is skipped (N in S156). If the data mismatch portion is the target of rewriting (Y in S160), the data portion is read from the first ROM 208 and rewritten to the first RAM 204 (S162) and must be the target of rewriting. For example, S162 is skipped (N in S160). If the data mismatch is the target of restart (Y of S164), the pachinko gaming machine 10 is restarted by reset or forced termination (S166), and if it is not the target of restart, S166 is skipped (S164) N). Note that the interrupt process in this figure is subject to inspection in many of the processes executed in various parts of the overall process in FIGS. 5 to 8, so it is difficult to figure out which step is specifically called from which step. The illustration is omitted so as not to occur. When it is determined that the checksum does not match in S154, two or more of the error notification in S158, the data rewriting in S162, and the restart in S166 may be executed. On the other hand, an emergency process is assigned so that at least one of them is always executed.

  In the above, this invention was demonstrated based on the Example. This embodiment is merely an example, and it will be understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and such modifications are within the scope of the present invention. is there.

  In the above embodiment, an example has been described in which collation by the data monitoring unit and collation by the data inspection unit are executed on both the main board 102 and the sub board 104. In the modification, the configuration may be such that the verification by the data monitoring unit and the verification by the data inspection unit are executed only on either the main board 102 or the sub board 104. For example, if one of the main board 102 and the sub-board 104 has a configuration that does not have a RAM, it is naturally not necessary to collate data on that board.

  In the above-described embodiment, the example in which both the collation by the data monitoring unit and the collation by the data inspection unit are used properly has been described. In the modified example, only one of the collation by the data monitoring unit and the collation by the data inspection unit may be used. For example, a configuration may be adopted in which a data portion that may cause a fatal malfunction due to data mismatch is read directly from the ROM without being developed in the RAM, and verification by the data monitoring means is used only for the non-fatal data portion. Or it is good also as a structure which uses the collation by a data test | inspection means only about the data part in which the mismatch of data may produce a fatal malfunction, and reads another data part directly from ROM.

  In the above-described embodiment, data rewriting is not illustrated as an emergency process when there is data mismatch as a result of collation by the data monitoring means. In the modified example, even in the emergency process for the collation result by the data monitoring unit, the data rewriting may be adopted according to the classification of the data portion.

  In the above-described embodiment, three cases of error notification, data rewriting, and restart have been illustrated and described as emergency processing when data mismatch occurs. In the modification, only a part of the above three methods may be adopted as an emergency process option, or an emergency process different from these may be further adopted as an option.

  In the above embodiment, an example has been described in which a data portion that is not a verification target by the data inspection unit is a verification target by the data monitoring unit. In the modified example, the entire RAM including the data portion to be collated by the data inspection unit may be the collation target by the data monitoring unit.
