Description

  The present invention relates to a gaming machine such as a pachinko machine, and more particularly to a gaming machine provided with two start winning devices and two symbol displays.

  In recent years, in order to enhance the fun of games by performing more various effects, gaming machines that perform games using two types of symbols, special symbols and decorative symbols (effect symbols), have been proposed. The special symbol is a symbol determined by the main control means, and includes information such as the type of jackpot (probability variation jackpot with probability variation or non-probability variation jackpot with no probability variation) and the number of rounds in the jackpot gaming state. It is out. On the other hand, the decorative symbol is a symbol that varies in synchronization with the variation of the special symbol.

In addition, by changing the decorative design in a state that can not be clearly identified as non-probable big hit, so that the player will not know whether the probability variation state will be given later, after the jackpot gaming state ends For the first time, a gaming machine that has been notified of the provision of a probability variation state has been proposed (see, for example, Patent Document 1). In the prior art described in Patent Document 1, the player has an expectation to give a probability variation state to the player until the big hit gaming state is finished by watching the effect using the decorative design. You can make it.
JP-A-2006-61619 (FIGS. 25, 26, etc.)

  However, since the special symbol is fixed and stopped when the symbol variation ends (that is, the time before the big hit gaming state is started), the player can see the special symbol and the probability variation state is given in advance. There is a possibility of being grasped. Therefore, in order to solve this problem, it is necessary to increase the types of special symbols to make it difficult to grasp the provision of the probability variation state. However, since the symbol display data associated with the special symbol is normally stored in the data table in the same number as the number of the special symbol, the data capacity of the symbol display data increases when the number of the special symbol is increased. The burden on the main control means is increased. For example, if there are 100 kinds of special symbols, symbol display data of 100 bytes is required. Further, the main control means has a data capacity limitation, and also requires a data capacity of a program for realizing various game characteristics (such as small hits and shortening of the variation time). Therefore, in order to improve the interest of the game, there is a situation that the data capacity of the symbol display data cannot be increased.

  The present invention has been made in view of the above problems, and its purpose is to improve the interest of games by increasing the types of symbols while suppressing the data capacity of a program necessary for generating symbol display data. It is to provide a game machine that can be used.

  In order to solve the above-described problem, the invention described in claim 1 is based on the first start winning device, the second starting winning device, and the winning of a game ball to the first starting winning device. A first symbol display that performs a first symbol variation game that varies a symbol, and a second symbol that performs a second symbol variation game that varies the second symbol in response to winning of a game ball to the second start winning device. A gaming machine comprising a display and gaming control means for controlling the entire gaming machine, wherein a first winning signal output for outputting a first winning signal when a gaming ball has won the first start winning device Means, a second winning signal output means for outputting a second winning signal when a game ball has won the second starting winning device, and a symbol number expressed by including a plurality of digits. Symbol number table that stores symbol number table The first bit table in which the bit value of the specific area is 1 or 0 and all the bit values of the remaining area are 0, and all the bit values of the specific area are 0, Bit table storage means for storing a second bit table in which the bit value of the remaining area is 1 or 0, the first bit table corresponding to the value of the upper digit in the symbol number, and the specific Upper byte data composed of a region bit and the remaining region bit is distributed, and the second bit table corresponds to a lower digit value in the symbol number, and the specific region bit and the remaining bit The lower byte data composed of the bits in the area is distributed, and the first bit table and the second bit table vary the first symbol. The table is commonly used both when the first symbol variation game is performed and when the second symbol variation game is performed to vary the second symbol, and the game control means includes the first winning signal. When the first winning signal is input from the output means or the second winning signal is input from the second winning signal output means, the result of the first symbol variation game or the second symbol variation game is a big hit. A jackpot determination means for determining whether or not to become, a random number acquisition means for acquiring a value of a design random number extracted by random lottery triggered by the input of the first winning signal or the second winning signal; and the random number A symbol number is determined from the symbol number table stored in the symbol number table storage unit based on the value of the random number for symbol acquired by the acquiring unit, and the determined symbol number The symbol determining means for determining the first symbol or the second symbol with reference to a number, and the upper digit corresponding to the value of the upper digit constituting the symbol number based on the symbol number determined by the symbol determining means Based on the upper byte data selecting means for selecting byte data from the first bit table, and the symbol number determined by the symbol determining means, the lower byte data corresponding to the value of the lower digit constituting the symbol number is Lower byte data selection means selected from the second bit table, bits in a specific area constituting upper byte data selected by the upper byte data selection means, and lower byte data selected by the lower byte data selection means ORs the bits of the specific area to be configured and selects them by the upper byte data selection means ORed with the bits of the remaining area constituting the upper byte data and the bits of the remaining area constituting the lower byte data selected by the lower byte data selecting means. A symbol display data generating means for generating the symbol display data, and a control for displaying the first symbol on the first symbol display based on the symbol display data generated by the symbol display data generating means, or The gist of the gaming machine is characterized by comprising display control means for controlling the second symbol display to display the second symbol.

  Therefore, in the first aspect of the present invention, the symbol display data is not stored in the data table in advance, but only when the symbol determining means determines the symbol number, the symbol display data generating means is the upper byte data. And the lower byte data are ORed. The type of byte data (upper byte data and lower byte data) used for generating the symbol display data is at least the same as the sum of the upper digit type and the lower digit type constituting the symbol number. The number of types of byte data can be made smaller than the number of symbol numbers. In addition, since the first bit table and the second bit table are tables commonly used in both the case where the first symbol is changed and the case where the second symbol is changed, the byte data included in each bit table is changed. The number of types can be reduced more reliably. Therefore, even if the types of the first symbol and the second symbol are enormous, the data capacity of the program used for generating the symbol display data can be suppressed, and the burden on the game control means can be reduced. In other words, the data capacity of the program for realizing various game characteristics can be increased by the amount of compression of the data capacity of the program necessary for generating the symbol display data, so that the interest of the game is improved.

  Here, suitable examples of the first symbol display and the second symbol display include a liquid crystal display, a dot matrix display, an electroluminescence element display, a 7 segment display, and the like. Moreover, as another 1st symbol display and 2nd symbol display, what consists of a some light emission part, what combined the some light emission part, and said indicator, etc. are mentioned. Although any conventionally known light emitting means can be used as the light emitting portion, it is preferable to use a light emitting diode (LED) having advantages of small size, long life, and power saving.

  In the first bit table, the values of the bits in the specific area are 1 or 0, and the values of the bits in the remaining area are all 0, while in the second bit table, the values of the bits in the specific area are all 0, and the bit values of the remaining areas are 1 or 0. When the upper byte data allocated to the first bit table is 8-bit (= 1 byte) data composed of the first to eighth digits, the first bit table is divided into a specific area, a remaining area, As a method of dividing the area, the area corresponding to the 1st digit, 2nd digit, 4th digit, and 8th digit bit is set as the specific area, and the 3rd digit, 5th digit, 6th digit, and 7th digit bit are changed. The method of setting the corresponding area as the remaining area, or the area corresponding to the upper 4 bits (1st to 4th bits) as the specific area and the lower 4 bits (5th to 8th bits) The method of setting the corresponding area as the remaining area, or the area corresponding to the upper 3 bits (1st to 3rd bits) as the specific area, and the lower 5 bits (4th to 8th bits) For example, a method may be used in which the corresponding area is the remaining area. The areas corresponding to the 1st digit, 2nd digit, 4th digit, and 8th digit bits are defined as specific areas, and the areas corresponding to the 3rd digit, 5th digit, 6th digit, and 7th digit bits are defined. In the case of the remaining area, the area corresponding to the first digit, second digit, fourth digit, and eighth digit bit of the second bit table is the specific region, and the third digit and fifth digit of the second bit table. The areas corresponding to the 6th and 7th digit bits are the remaining areas. If the area corresponding to the upper 4 bits is the specific area and the area corresponding to the lower 4 bits is the remaining area, the upper 4 bits (1st to 4th bits) of the 2nd bit table are supported. The area to be processed is the specific area, and the area corresponding to the lower 4 bits (bits 5 to 8) of the second bit table is the remaining area. Furthermore, when the area corresponding to the upper 3 bits is a specific area and the area corresponding to the lower 5 bits is the remaining area, it corresponds to the upper 3 bits (bits 1 to 3) of the second bit table. The area to be processed is a specific area, and the area corresponding to the lower 5 bits (bits 4 to 8) of the second bit table is the remaining area.

  Further, each of the first symbol display and the second symbol display is composed of 8 or less light emitting units, and each of the light emitting units is turned on or off according to the value of a plurality of digits constituting the symbol display data. In the case of turning off the light, it is preferable that the bits constituting the specific area of the first bit table and the bits constituting the remaining area of the second bit table are irregularly arranged. For example, when byte data 1 to 15 exist in order and the specific area of the first bit table is composed of four bits, the bits of each specific area are set to “0100”, “0110”, “1100”, “0010”. , “1101”,..., “1010”. When bits constituting a specific area are regularly arranged, the bits of each specific area are in the order of “0001”, “0010”, “0011”, “0100”, “0101”,..., “1111”. It will be lined up. In this way, regularity is not easily generated in the light emission mode of each light emitting unit, and it becomes impossible to grasp which light emitting unit is lit up and the probability variation state is reached.

  According to a second aspect of the present invention, in the first aspect, the game control unit includes a plurality of bits constituting upper byte data corresponding to the symbol number determined by the symbol determination unit, and the symbol determination unit. By confirming the value of a predetermined bit among a plurality of bits constituting the lower byte data corresponding to the decided symbol number, at least one of the upper digit and the lower digit constituting the symbol number determined by the symbol determining means A change process execution determination unit that determines whether or not to execute a change process that changes the value of the change, and a change process execution that executes the change process when the change process execution determination unit determines to execute the change process And when the change process is executed by the change process execution means, the upper byte data selection means The upper byte data corresponding to the upper digit value obtained as a result of executing the further processing is selected, and the lower byte data selecting means corresponds to the lower digit value obtained as a result of executing the change processing. The gist is to select the lower byte data.

  According to the second aspect of the present invention, each byte data is assigned to the upper byte data selecting means and the lower byte data selecting means using the symbol number in which at least one of the upper digit and the lower digit is changed by the changing process. And the symbol display data generating means generates symbol display data based on the selected byte data. For this reason, it becomes difficult for regularity to appear in the values of a plurality of bits constituting the symbol display data. Therefore, the first symbol display unit and the second symbol display unit are each composed of a plurality of light emitting units, and the respective light emitting units are turned on or off according to the values of a plurality of bits constituting the symbol display data. Furthermore, regularity is less likely to appear in the light emission mode of each light emitting part. Therefore, since the player cannot grasp which light-emitting part is turned on to change the probability variation state, the interest of the game is further improved.

  In addition, as a method of changing at least one value of the upper digit and the lower digit in the changing process, a method of adding at least one value of the upper digit and the lower digit, a method of subtracting, and the like can be cited.

  The invention according to claim 3 is the case where the symbol number determined by the symbol determining means determines the first symbol and the symbol that determines the second symbol in claim 2. The gist is that the contents of the change process are different.

  Therefore, according to the invention described in claim 3, even if the symbol number used for determining the first symbol and the symbol number used for determining the second symbol are the same, by performing the change process, Different symbol display data can be generated.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, the first symbol display unit and the second symbol display unit each include eight light emitting units or less, and at least one The gist of the present invention is that the shape of the light emitting part is made different between the first symbol display and the second symbol display.

  In the present invention, since the first bit table and the second bit table are used in common in both the case where the first symbol variation game is performed and the case where the second symbol variation game is performed, the display of the first symbol display device is performed. There is a possibility that the form and the display form of the second symbol display device will coincide. Therefore, in the invention according to claim 4, since the shape of at least one light emitting portion is different between the first symbol display and the second symbol display, even if they are the same light emission mode, The display form of the first symbol displayed on the first symbol display and the display form of the second symbol displayed on the second symbol display can be surely different.

  In addition, examples of the shape of the light emitting unit include a circular shape, an elliptical shape, a triangular shape, a rectangular shape, a star shape, and a moon shape. In addition, when each of the first symbol display and the second symbol display is composed of eight light emitting units, the seven light emitting units are set as a seven-segment display, and the shape of the remaining one light emitting unit is set. It is preferable that the first symbol display and the second symbol display have different shapes. If it does in this way, a 1st symbol display and a 2nd symbol display can be comprised only by adding a little change to the 7 segment type display used conventionally. Here, the remaining one light emitting section may be provided in the visible display section of the 7-segment display, or may be provided separately from the visible display section.

  As described in detail above, according to the first to fourth aspects of the present invention, the interest of the game is improved by increasing the types of symbols while suppressing the data capacity of the program necessary for generating the symbol display data. It is possible to provide a gaming machine that can be used. In particular, according to the second aspect of the present invention, regularity is less likely to appear in the values of a plurality of bits constituting the symbol display data, so that the interest of the game is further improved.

Each of the reserved lamps D1 to D4 is for indicating the number of special symbol reserved balls (second special symbol reserved ball number). For example, when there are three special symbol holding balls, three holding lamps D1 to D3 are lit.

  Here, the “second special symbol reserved ball number” is the predetermined maximum number of game balls won in the second start winning device 22 during the fluctuation of the second special symbol B2 (the second decorative symbol E2). It is a value stored in the range of the value (4 in this embodiment). The number of second special symbol reserved balls is “+1” by winning a game ball to the second start winning device 22, and is “−1” by starting the second variation game.

  As shown in FIG. 2, a normal symbol display device 53 having a visible display portion is disposed at the lower left portion of the symbol display device 60. In the normal symbol display device 53, when a game ball is detected by the gate 25, a normal symbol variation game by the normal symbol is executed, and the normal symbol indicating the result of random number lottery is obtained as a result of the normal symbol variation game. Is displayed. Note that there are two types of normal symbols in the present embodiment: a winning symbol “◯” or a lost symbol “X”. When the winning symbol is derived (when the normal symbol variation game is won), the normal electric accessory solenoid SOL1 is driven for a predetermined time, and the pair of blade members are opened.

  A normal symbol holding display device F is disposed below the normal symbol display device 53. The normal symbol hold display device F is constituted by a plurality of (four) light emitting means including a first hold lamp F1, a second hold lamp F2, a third hold lamp F3, and a fourth hold lamp F4. The holding lamps F <b> 1 to F <b> 4 are turned on when there is a game ball (ordinary symbol holding ball) stored with the passage of the gate 25 as an opportunity, and turned off when there is no normal symbol holding ball. Each of the reserved lamps F1 to F4 is for indicating the number of normal symbol reserved balls (ordinary symbol reserved balls). For example, when there are two normal symbol holding balls, two holding lamps F1 and F2 are lit.

  Here, the “ordinary symbol reserved ball number” is a value stored in a range of a predetermined maximum value (4 in the present embodiment), the number of game balls that have passed through the gate 25. The number of normal symbol reserved balls is “+1” when the game ball passes through the gate 25 and is “−1” when the normal symbol variation game is started.

As shown in FIG. 1, a lower left outer prize opening device 35a and a lower left inner prize opening device 35b are arranged on the left side of the large winning device 24 in the game area 13a. A winning port switch SE5 (see FIG. 4) for detecting a winning game ball is provided in the back of the lower left outer winning port device 35a and the lower left inner winning port device 35b. That is, in the lower left outer prize opening device 35a and the lower left inner prize opening device 35b, the winning of a game ball is detected by one winning prize switch SE5. In the game area 13a, a lower right outer prize opening device 36a and a lower right inner prize opening device 36b are arranged on the right side of the big winning device 24. A winning hole switch SE6 (see FIG. 4) for detecting a winning game ball is provided in the back of the lower right outer winning hole device 36a and the lower right inner winning port device 36b. That is, in the lower right outer prize opening device 36a and the lower right inner prize opening device 36b, the winning of the game ball is detected by the single prize opening switch SE6. These prize opening devices 35a, 35b, 36a, 36b are configured to pay out a predetermined number (10 in this embodiment) of prize balls when a game ball is awarded.

As shown in FIGS. 4 and 5, the pachinko machine 10 includes a main control board 31, an overall control board 37, a display control board 33, and an audio / lamp control board 34. An overall control board 37 is electrically connected to the main control board 31, and a display control board 33 and an audio / lamp control board 34 are electrically connected to the overall control board 37.
(2-1) Electrical configuration of main control board 31

  As shown in FIGS. 4 and 5, the main control board 31 includes a main CPU 31 a as “game control means” for controlling the entire pachinko machine 10. The main CPU 31a is connected to the first start port switch SE1, the second start port switch SE2, the count switch SE3, the gate switch SE4, and the winning port switches SE5 and SE6. The main CPU 31a includes the first special symbol display 51, the second special symbol display 52, the first special symbol hold display device C, the second special symbol hold display device D, and the normal symbol display device. 53 and the normal symbol hold display device F are connected. In addition, the main CPU 31a is connected to the ordinary electric accessory solenoid SOL1 and the special prize opening solenoid SOL2.

  As shown in FIG. 5, a main ROM 31b and a main RAM 31c are electrically connected to the main CPU 31a. The main CPU 31a uses a first big hit determination random number, a first big hit symbol random number, a second big hit symbol random number, a second big hit symbol random number, a first reach determination random number, Various random numbers such as reach determination random numbers and fluctuation pattern distribution random numbers are updated every predetermined period. Then, the main CPU 31a sets the updated value in the random number storage area of the main RAM 31c and rewrites the value before the update. Various flags that are appropriately rewritten during the operation of the pachinko machine 10 are stored (set) in the flag storage area of the main RAM 31c. In the timer storage area of the main RAM 31c, various timers that are appropriately rewritten during operation of the pachinko machine 10 are stored (set).

  The first big hit determination random number is a random number used when determining whether or not the first variable game is a big hit (when determining the first big hit), and the second big hit determination random number is the second fluctuation. This is a random number used when determining whether or not the game is a big hit (when determining the second big hit). The first jackpot symbol random number is a random number used when determining the first special symbol B1 when the result of the first variation game is a jackpot, and the second jackpot symbol random number is that of the second variation game. This is a random number used when determining the second special symbol B2 when the result is a big hit. The first reach determination random number is a random number used when determining whether or not to execute the reach effect when the result of the first variation game is a loss (during reach determination), and the second reach determination random number. Is a random number used when deciding whether or not to execute the reach effect when the result of the second variation game is a loss (during reach determination). The variation pattern distribution random number is a random number used when determining the variation pattern for specifying the effect contents of the game effect in the first symbol combination game and the second symbol combination game.

  The main ROM 31b shown in FIG. 5 stores a variation pattern distribution table in which variation patterns for the first symbol combination game (first variation game) and the second symbol combination game (second variation game) are allocated. ing. In each variation pattern, the symbols in all the columns are stopped after the symbols (the first decorative symbol E1) in each column displayed on the first symbol display unit 61 start changing (the first symbol combination game is started). This is for specifying the time and contents of the game effect (display effect, light emission effect, sound effect) until the end of the first symbol combination game, and is displayed on the second symbol display unit 62. This is for specifying the time and contents of the game effect from when the symbols in each row (the second decorative symbol E2) start to change until the symbols in all rows stop. That is, the variation pattern is a pattern that is commonly used in the first variation game and the second variation game. In the variation pattern distribution table of the present embodiment, a variation pattern for a loss effect, a variation pattern for a loss reach effect, and a variation pattern for a jackpot effect are distributed. It should be noted that the variation pattern for losing effect indicates a pattern serving as a base of losing effect for deriving a losing symbol combination (a symbol combination from which a symbol combination that is a big hit or reach is not derived). The variation pattern for the hustle reach production shows a pattern that is a base of the hustle reach production where the middle symbol stops at a symbol different from the left symbol and the right symbol. The variation pattern for the jackpot effect indicates a pattern that becomes the base of the jackpot effect in which the middle symbol stops at the same symbol as the left symbol and the right symbol. In addition, the production time (fluctuation time) of the lost production, the lost reach production, and the jackpot production is different for each variation pattern. Each variation pattern is assigned a variation pattern distribution random number value (100 integers from 0 to 99 in this embodiment).

  The main ROM 31b shown in FIG. 5 stores a symbol number table. That is, the main ROM 31b has a function as “symbol number table storage means”. In the symbol number table, the symbol for specifying the first special symbol B1 (or the second special symbol B2) when the result of the first symbol variation game (or the second symbol variation game) is a big hit. Numbers 0 to 239 are listed. That is, the symbol number is commonly used in the first symbol variation game and the second symbol variation game. Each symbol number 0 to 239 has a value of the first big hit symbol random number (in this embodiment, 240 integers from 0 to 239) and a value of the second big hit symbol random number (this example) In the form, 240 integers of 0 to 239) are distributed. Each symbol number 0 to 239 is displayed in hexadecimal, and is a number that includes two digits. For example, the symbol number 83 is a number “53H (hexadecimal number)”.

  The symbol numbers 0 to 239 are respectively associated with the first special symbols B1 of “0” to “239”. More specifically, the symbol numbers 0 to 62 are respectively associated with the first special symbols B1 of “0” to “62” selected when the so-called “15R probability variation big hit” is selected. Similarly, the symbol numbers 63 to 105 are respectively associated with the first special symbols B1 of “63” to “105” that are selected when the so-called “8R probability variation big hit” is made. Are associated with the first special symbols B1 of “106” to “141” selected when the so-called “2R probability variation big hit” is made. Furthermore, the symbol numbers 142 to 179 are respectively associated with the first special symbols B1 of “142” to “179” that are selected when the so-called “15R normal big hit” is made. Are associated with the first special symbols B1 of “180” to “207” selected when the so-called “8R normal big hit” is made, and the symbol numbers 208 to 239 are so-called “2R normal big hit”. The first special symbols B1 of “208” to “239” selected when

  In addition, the symbol numbers 0 to 239 are respectively associated with the second special symbols B2 of “0.” to “239.”. More specifically, the symbol numbers 0 to 73 are associated with the second special symbols B2 of “0.” to “73” selected when the “15R probability variation big hit” is selected. 140 is associated with second special symbols B2 of “74.” to “140.” selected when “8R probability variation big hit” is selected. Similarly, the symbol numbers 141 to 195 are associated with the second special symbols B2 of “141.” to “195.” that are selected when “15R normal big hit”, respectively. 239 is associated with second special symbols B2 of “196.” to “239.” selected when “8R normal big hit” is obtained. Therefore, when the second special symbol B2 is selected, “2R probability variation big hit” and “2R normal big hit” are not given.

  Therefore, in the present embodiment, the first special symbol B1 of “0” to “141” associated with the symbol numbers 0 to 141 is the specific symbol to which the special symbol probability variation state is given, and the symbol numbers 142 to 239 are assigned. The associated first special symbols B1 of “142” to “239” are non-specific symbols to which no special symbol probability variation is given. In the present embodiment, the second special symbol B2 of “0.” to “140.” associated with the symbol numbers 0 to 140 becomes the specific symbol, and “141.” associated with the symbol numbers 141 to 239. The second special symbol B2 of “239.” is a non-specific symbol.

  Here, “15R probability variation big hit” means that after 15 round effects are executed in the big hit gaming state given when the result of the first symbol variation game or the second symbol variation game is a big hit. In this state, a special symbol probability variation state is given. “8R probability variable big hit” means a special symbol probability fluctuation state after eight round effects are executed in the big hit gaming state given when the result of the first symbol variation game or the second symbol variation game is a big hit. Is a state to which is given. “2R probability variable big hit” is a state where a special symbol probability fluctuation state is given after two round effects are executed in the big hit gaming state given when the result of the first symbol fluctuation game is a big hit. It is. On the other hand, “15R normal big hit” means that after the round effect is executed 15 times in the big hit gaming state given when the result of the first symbol variation game or the second symbol variation game is a big hit, the normal game This is a state to which a state is given. “8R normal jackpot” means that in the jackpot gaming state given when the result of the first symbol variation game or the second symbol variation game is a jackpot, after the eight round effects are executed, the normal gaming state is It is a state to be granted. “2R normal big hit” is a state in which the normal gaming state is given after two round effects are executed in the big hit gaming state given when the result of the first symbol variation game is a big hit. . Note that the special symbol probability variation state is a state in which the jackpot lottery probability varies with a high probability in the first symbol variation game (the first symbol combination game) or the second symbol variation game (the second symbol combination game). Yes, the normal gaming state is a normal state that does not become a special symbol probability fluctuation state.

  Here, “15R probable big hit”, “15R normal big hit”, “8R probable big hit”, and “8R normal big hit” are big hit gaming states in which a predetermined number of prize balls are paid out. On the other hand, “2R probability variation big hit” and “2R normal variation big hit” are more open than the “15R certain variation big hit”, “15R normal variation big hit”, “8R positive variation big hit” and “8R normal big hit”. The time is short and it is relatively difficult to win game balls. In the present embodiment, when the special symbol probability variation state is given after the end of the jackpot gaming state given as a result of the first symbol variation game, the pair of blade members of the ordinary electric accessory 22b is released. This makes it easier for a game ball to win the second start winning device 22.

  In the present embodiment, the display of the first symbol display unit 61 is performed even when “2R probability variation big hit” is given or when “2R normal big hit” is given in the first variation game. The contents (the first decorative design E1, the background, etc.) are the same. Thereby, it becomes a secrecy mode which conceals grant or non-given of a special symbol probability variation state.

  Furthermore, in this embodiment, even when the jackpot gaming state in which eight round effects are executed is executed, or in the case where the jackpot gaming state in which 15 round effects are executed is executed, The display contents of each round effect (the first decorative design E1 or the second decorative design E2, the background, etc.) are the same. For this reason, even if the player sees the effect symbol (the first ornament symbol E1 or the second ornament symbol B2), the number of round effects (the number of rounds) executed during the big hit gaming state or the special symbol probability variation state It is in a state where it cannot be determined whether or not is given. Therefore, in the present embodiment, in the case of a big hit gaming state in which 15 round effects are executed, the round promotion effect is executed until 8 round effects are executed. In the case of the big hit gaming state where “8R probability change big hit” is given, the probability change notification effect for giving the special symbol probability fluctuation state is executed until eight round effects are executed. ing. Similarly, in the big hit gaming state in which “15R probability change big hit” is given, the probability change notification effect is executed until 15 round effects are executed. The round promotion effect of the present embodiment is an effect of displaying the characters “15R confirmed” on the first symbol display unit 61 or the second symbol display unit 62. Further, the probability change notification effect of the present embodiment is an effect of displaying the characters “probability change” on the first symbol display unit 61 or the second symbol display unit 62.

  The main ROM 31b shown in FIG. 5 stores a first bit table (see FIG. 6A) and a second bit table (see FIG. 6B). That is, the main ROM 31b has a function as “bit table storage means”. The first bit table and the second bit table are tables that are commonly used both when the first symbol variation game and the second symbol variation game are performed. In the first bit table, the value of the upper 4 bits (bits of the first digit to the fourth digit) that are “bits of the specific area” is “1” or “0”, and the lower bits that are “bits of the remaining area” This is a table in which all values of 4 bits (bits 5 to 8) are “0”. In the first bit table, upper byte data 0 to 14 composed of upper 4 bits and lower 4 bits are distributed. The upper byte data 0 to 14 is data having a data capacity of 1 byte, and corresponds to the value of the upper digit in the symbol number (in this embodiment, the value of the upper digit when displayed in hexadecimal). For example, in the case of the symbol number “53H”, the upper byte data 4 (“11010000”) corresponds to the upper digit value “5”. Note that the values of the upper 4 bits of the first bit table are arranged irregularly. More specifically, the upper 4 bits constituting the upper byte data 0 are “0100”, the upper 4 bits constituting the upper byte data 1 are “0110”, and the upper 4 bits constituting the upper byte data 2 are “1100”. The upper 4 bits constituting the upper byte data 3 are “0010”, the upper 4 bits constituting the upper byte data 4 are “1101”, the upper 4 bits constituting the upper byte data 5 are “0101”, and the upper byte data 6 The upper 4 bits constituting the upper byte data 7 are “1110”, the upper 4 bits constituting the upper byte data 7 are “1000”, the upper 4 bits constituting the upper byte data 8 are “1011”, and the upper 4 bits constituting the upper byte data 9 The bit is “0111” and the upper 4 bits constituting the upper byte data 10 are “1001”. 4 bits are “0001”, upper 4 bits constituting upper byte data 12 are “1111”, upper 4 bits constituting upper byte data 13 are “0011”, and upper 4 bits constituting upper byte data 14 are “1010”. "

  On the other hand, in the second bit table, all the values of the upper 4 bits (the first digit to the fourth digit) are “0”, and the values of the lower 4 bits (the fifth digit to the eighth digit) are “ The table is “1” or “0”. In the second bit table, lower byte data 0 to 15 composed of upper 4 bits and lower 4 bits are distributed. The lower byte data 0 to 15 are data having a data capacity of 1 byte, and correspond to the lower digit value in the symbol number (in this embodiment, the lower digit value displayed in hexadecimal). For example, in the case of the symbol number “53H”, the lower byte data 2 (“00000100”) corresponds to the lower digit value “3”. Note that the values of the lower 4 bits of the second bit table are arranged irregularly. Specifically, the lower 4 bits constituting the lower byte data 0 are “0000”, the lower 4 bits constituting the lower byte data 1 are “0010”, and the lower 4 bits constituting the lower byte data 2 are “0100”. The lower 4 bits constituting the lower byte data 3 are “1111”, the lower 4 bits constituting the lower byte data 4 are “1101”, the lower 4 bits constituting the lower byte data 5 are “0101”, and the lower byte data 6 4 is “0111”, the lower 4 bits constituting the lower byte data 7 is “0001”, the lower 4 bits constituting the lower byte data 8 is “0011”, and the lower 4 bits constituting the lower byte data 9 Bit is “1100”, lower 4 bits constituting lower byte data 10 is “1010”, lower byte data 11 is lower The lower 4 bits constituting the lower byte data 12 are “0110”, the lower 4 bits constituting the lower byte data 13 are “0011”, and the lower 4 bits constituting the lower byte data 14 are “1000”. The lower 4 bits constituting the lower byte data 15 are “1001”.

  As shown in FIG. 3 and FIG. 6, the value (“1” or “0”) of each bit in the first bit table and the second bit table indicates each light emission constituting the first special symbol display 51. It is for deciding the lighting mode of each light emission part 57a-57h which comprises the parts 55a-55h and the said 2nd special symbol indicator 52. FIG. More specifically, the first digit bit (segH) corresponds to the light emitting units 55h and 57h, the second digit bit (segG) corresponds to the light emitting units 55g and 57g, and the third digit bit (segF). Corresponds to the light emitting units 55f and 57f, the fourth digit bit (segE) corresponds to the light emitting units 55e and 57e, the fifth digit bit (segD) corresponds to the light emitting units 55d and 57d, and the sixth digit bit. The bit (segC) corresponds to the light emitting units 55c and 57c, the seventh digit bit (segB) corresponds to the light emitting units 55b and 57b, and the eighth digit bit (segA) corresponds to the light emitting units 55a and 57a. Yes. Each of the light emitting units 55a to 55h and 57a to 57h is turned on when the bit value of the corresponding digit is “1”, and is turned off when the value of the bit of the corresponding digit is “0”. It has become.

  Next, various processes (first jackpot determination, second jackpot determination, reach determination, etc.) related to the symbol variation game executed by the main CPU 31a shown in FIGS. 4 and 5 will be described. The main ROM 31b stores programs (random number acquisition program, jackpot determination program) used for the various processes described above.

  The random number acquisition program is a program for causing the main CPU 31a to function as “random number acquisition means”. That is, the main CPU 31a is extracted by random number lottery and updated at predetermined intervals when the start winning condition is satisfied (output of the first winning signal from the first start port switch SE1). The value of the first big hit symbol random number which is “random number” is acquired from the main RAM 31c, and the acquired value is stored (stored) in the random number storage area of the main RAM 31c. Similarly, the main CPU 31a is extracted by random number lottery and updated at predetermined intervals when the start winning condition is satisfied (output of the second winning signal from the second start port switch SE2). The value of the second big hit symbol random number as “random number for use” is acquired from the main RAM 31c, and the acquired value is stored (stored) in the random number storage area of the main RAM 31c. The main CPU 31a takes the value of the first jackpot determination random number or the second jackpot determination random number extracted by random number lottery and updated every predetermined period as a trigger when the start winning condition is satisfied. Obtained from the RAM 31c and stores (stores) the obtained value in the random number storage area of the main RAM 31c.

  The big hit determination program is a program for causing the main CPU 31a shown in FIGS. 4 and 5 to function as “big hit determination means”. That is, the main CPU 31a determines whether or not the result of the first symbol variation game or the second symbol variation game is a big hit. More specifically, the main CPU 31a immediately before the start of the first variation game, the first big hit determination random number stored in the random number storage area of the main RAM 31c and the first big hit determination value stored in the main ROM 31b. Are compared, and a first big hit determination (win lottery) is performed to determine whether or not the first variable game is successful. In the present embodiment, the numerical values that can be taken by the first big hit determination random number are set to 0 to 299 (all 300 different integers). Then, the main CPU 31a performs the first big hit determination by using one first big hit determination value from among the values that can be taken by the first big hit determination random number, and setting the big win lottery probability to 1/300.

  In addition, immediately before the start of the second variation game, the main CPU 31a uses the second big hit determination random number value stored in the random number storage area of the main RAM 31c and the second big hit determination value stored in the main ROM 31b. A second big hit determination (hit lottery) for determining whether or not the second variation game is successful is performed. In the present embodiment, the number that can be taken by the second jackpot determination random number is set to 0 to 299 (all 300 different integers). Then, the main CPU 31a performs the second jackpot determination by using one second jackpot determination value from among the numerical values that can be taken by the second jackpot determination random number and setting the jackpot lottery probability to 1/300. That is, the main CPU 31a makes a jackpot determination with the same lottery probability regardless of whether the game is the first variation game or the second variation game.

  When the determination result of the first big hit determination is negative (the value of the first big hit determination random number and the first big hit determination value do not match), the main CPU 31a shown in FIG. 4 and FIG. decide. Similarly, when the determination result of the second big hit determination is negative (the value of the second big hit determination random number and the second big hit determination value do not match), the main CPU 31a determines the lost gaming state.

  Further, when the determination result of the first big hit determination is negative, the main CPU 31a compares the first reach determination random number value read from the main RAM 31c with the first reach determination value stored in the main ROM 31b. Then, reach determination is made as to whether or not to execute lose reach. Similarly, when the determination result of the second jackpot determination is negative, the main CPU 31a compares the second reach determination random number value read from the main RAM 31c with the second reach determination value stored in the main ROM 31b. To determine whether or not to execute lose reach.

  If the reach determination result is affirmative (the first reach determination random number value matches the first reach determination value, or the second reach determination random number value matches the second reach determination value). The main CPU 31a shown in FIGS. 4 and 5 determines the lose reach. Further, when the determination result of reach determination is negative (the first reach determination random number value and the first reach determination value do not match, or the second reach determination random number value and the second reach determination value do not match). The main CPU 31a determines a loss (a loss that does not involve reach).

  On the other hand, when the determination result of the first big hit determination is affirmative (the value of the first big hit determination random number matches the first big hit determination value), the main CPU 31a determines the big hit. Similarly, when the determination result of the second big hit determination is affirmative (the value of the second big hit determination random number matches the second big hit determination value), the main CPU 31a determines the big hit.

  4 and 5, the first special symbol B1 is the specific symbol based on the value of the first big hit symbol random number stored in the random number storage area of the main RAM 31c. It is determined whether or not. In the present embodiment, if the value of the first jackpot symbol for random numbers is any of “0” to “141”, it is determined that the first special symbol B1 is a specific symbol, and the value of the first jackpot symbol for random numbers Is any one of “142” to “239”, it is determined that the first special symbol B1 is not the specific symbol but the non-specific symbol. Similarly, the main CPU 31a determines whether or not the second special symbol B2 is a specific symbol based on the value of the second big hit symbol random number stored in the random number storage area of the main CPU 31a. In the present embodiment, if the value of the second big hit symbol random number is between “0” and “140”, it is determined that the second special symbol B2 is a specific symbol, and the value of the second big hit symbol random number Is “141” to “239”, it is determined that the second special symbol B2 is a non-specific symbol.

  When it is determined that the first special symbol B1 or the second special symbol B2 is the specific symbol, the main CPU 31a shown in FIGS. 4 and 5 displays the special symbol probability variation state after the end of the jackpot gaming state. Start granting. When the special symbol probability variation state is started in the first variation game, the main CPU 31a uses 10 first jackpot determination values from among the values that can be taken by the first jackpot determination random number. The first jackpot determination is performed with a lottery probability of 10/300 (= 1/30). That is, the number of first jackpot determination values in the special symbol probability variation state is ten times that in the special symbol probability variation state. Similarly, when the special symbol probability variation state is started in the second variation game, the main CPU 31a uses ten second jackpot determination values from among the values that can be taken by the second jackpot determination random number, The second jackpot determination is performed with the jackpot lottery probability set to 10/300 (= 1/30). That is, the number of second jackpot determination values in the special symbol probability fluctuation state is 10 times that in the special symbol probability fluctuation state. Note that the special symbol probability variation state may be continued until the next jackpot gaming state is started, or the symbol variation display is executed a plurality of times (for example, 10,000 times). It may be continued for a while.

  Next, based on the determination results of the first jackpot determination, the second jackpot determination, and the reach determination, various processes related to the symbol variation game executed by the main CPU 31a shown in FIGS. Explain decision). The main ROM 31b includes programs used for the above-described various processes (design determination program, upper byte data selection program, lower byte data selection program, symbol display data generation program, display control program, change processing execution determination program, change Processing execution program) is stored.

  The symbol determining program is a program for causing the main CPU 31a shown in FIGS. 4 and 5 to function as “symbol determining means”. That is, when the big hit is determined in the first big hit determination, the main CPU 31a relates to the stop symbol (the first decorative symbol E1) derived in the first symbol combination game on the first symbol display unit 61. The first special symbol B1, which is a symbol, is determined. Specifically, the main CPU 31a determines the symbol number specified based on the value of the first jackpot symbol random number stored in the random number storage area of the main RAM 31c from the symbol number table. The first special symbol B1 is determined with reference to the symbol number. Similarly, when the big hit is determined in the second big hit determination, the main CPU 31a relates to the stop symbol (the second decorative symbol E2) derived in the second symbol combination game on the second symbol display unit 62. The second special symbol B2 which is a symbol to be determined is determined. Specifically, the main CPU 31a determines a symbol number specified based on the value of the second jackpot symbol random number stored in the random number storage area of the main RAM 31c from the symbol number table, and the determined symbol number The second special symbol B2 is determined with reference to FIG.

  When the loss or reach is determined in the first big hit determination, the main CPU 31a shown in FIGS. 4 and 5 uniquely determines the symbol number 240 associated with the symbol display data (“01000000”). Then, with reference to the determined symbol number 240, the first special symbol B1 is determined as a symbol “−” indicating a loss. That is, an offset process (change process), which will be described later, executed when a big hit is determined in the first big hit determination is not performed. Similarly, when the lose reach or the loss is determined in the second big hit determination, the main CPU 31a uniquely determines the symbol number 240 associated with the symbol display data ("01000000"), and determines the determined symbol number 240. The second special symbol B2 is determined as a symbol “−” indicating a loss. That is, the change process that is executed when the big hit is determined in the second big hit determination is not performed.

  The change process execution determination program is a program for causing the main CPU 31a to function as “change process execution determination means”. That is, the main CPU 31a determines the symbol number by confirming the value of the eighth digit among the eight digits constituting the lower byte data (see FIG. 6B) corresponding to the determined symbol number. It is determined whether or not to execute a change process for changing the value of the upper digit (in this embodiment, the value of the upper digit when displayed in hexadecimal) (change process execution determination). The change process execution program is a program for causing the main CPU 31a to function as “change process execution means”. That is, the main CPU 31a executes the change process when it is determined to execute the change process.

  More specifically, the main CPU 31a shown in FIG. 4 and FIG. 5 starts with the values of the upper and lower digits constituting the determined symbol number (in this embodiment, the upper and lower digits when displayed in hexadecimal). (Digit value). For example, in the case of the symbol number “53H”, the main CPU 31a confirms that the upper digit value is “5” and the lower digit value is “3”. Then, the main CPU 31a confirms the value of the eighth digit bit among the eight digits constituting the lower byte data corresponding to the determined symbol number (lower digit value). If the value of the eighth digit bit is an even number “0”, the main CPU 31a adds +7 to the value of the upper digit constituting the symbol number (first change process). If the value of the eighth digit bit is an odd number “1”, the main CPU 31a does not change the value of the upper digit and the value of the lower digit constituting the symbol number. For example, in the case of the symbol number “53H”, the lower digit value is “3”, and the corresponding lower byte data is the lower byte data 2 (“00000100”). The value of this bit is an even number “0”. Therefore, the main CPU 31a sets the upper digit value “5” to +7 and the upper digit value “12”.

  Here, if the symbol number determines the first special symbol B1, the main CPU 31a shown in FIGS. 4 and 5 determines the values of the upper and lower digits (offset values) at this time. For example, in the case of the symbol number “53H”, if the symbol number determines the first special symbol B1, the main CPU 31a fixes the upper digit value to “12” and sets the lower digit value to “3”. To confirm. On the other hand, if the symbol number determines the second special symbol B2, the main CPU 31a further increases the value of the upper digit by 2 (second change process). If the value obtained by adding +2 to the value of the upper digit is “15” or more (in this embodiment, “15” or “16”), the value of the upper digit is further −14 (third change process). Then, the main CPU 31a determines the values of the upper and lower digits (offset values) at this time. For example, if the symbol number determines the second special symbol B2 in the case of the symbol number “53H”, the main CPU 31a sets the upper digit value “12” obtained as a result of executing the first change process. +2 to set the upper digit value to “14”. At this time, since the value of the upper digit is less than “15”, the main CPU 31a determines the offset value of the upper digit to “14” and the offset value of the lower digit to “3”. That is, in the present embodiment, the contents of the change process are different between the case where the symbol number determines the first special symbol B1 and the case where the symbol number determines the second special symbol B2.

  The upper byte data selection program is a program for causing the main CPU 31a shown in FIGS. 4 and 5 to function as “upper byte data selection means”. That is, the main CPU 31a stores the upper byte data corresponding to the value of the upper digit (in this embodiment, the value of the upper digit when displayed in hexadecimal) constituting the determined symbol number in the first bit table ( (See FIG. 6A). In particular, when the change process is executed, the main CPU 31a selects the upper byte data corresponding to the upper digit value obtained as a result of executing the change process. For example, in the case of the symbol number “53H”, when the symbol number is to determine the first special symbol B1, the value of the upper digit obtained as a result of executing the changing process is “12”. In this case, the main CPU 31a selects the twelfth upper byte data 11 (“00010000”) from the first bit table. On the other hand, in the case of the symbol number “53H”, when the symbol number is to determine the second special symbol B2, the value of the upper digit obtained as a result of executing the changing process is “14”. In this case, the main CPU 31a selects the 14th upper byte data 13 (“00110000”) from the first bit table.

  The lower byte data selection program is a program for causing the main CPU 31a shown in FIGS. 4 and 5 to function as “lower byte data selection means”. That is, the main CPU 31a stores the lower byte data corresponding to the lower digit value (in this embodiment, the lower digit value when displayed in hexadecimal) constituting the determined symbol number in the second bit table ( (See FIG. 6B). In particular, when the change process is executed, the main CPU 31a selects lower byte data corresponding to the lower digit value obtained as a result of executing the change process. For example, in the case of the symbol number “53H”, the value of the lower digit obtained as a result of executing the changing process is “3”. In this case, the main CPU 31a selects the third lower byte data 2 (“00000100”) from the second bit table.

  The symbol display data generation program is a program for causing the main CPU 31a shown in FIGS. 4 and 5 to function as “symbol display data generation means”. That is, the main CPU 31a performs an OR process on the upper 4 bits constituting the upper byte data and the upper 4 bits constituting the lower byte data, and at the same time, the lower 4 bits constituting the upper byte data and the lower 4 bits constituting the lower byte data. By ORing the bits, symbol display data composed of 8-digit bits is generated. For example, when the symbol number is “53H” and the symbol number determines the first special symbol B1, the twelfth upper byte data 11 (“00010000”) from the first bit table (see FIG. 6A). ) Is selected, and the third lower byte data 2 (“00000100”) is selected from the second bit table (see FIG. 6B). In this case, when the upper 4 bits (“0001”) constituting the upper byte data 11 and the upper 4 bits (“0000”) constituting the lower byte data 2 are ORed, the upper 4 bits of the symbol display data are “0001”. " When the lower 4 bits (“0000”) constituting the upper byte data 11 and the lower 4 bits (“0100”) constituting the lower byte data 2 are ORed, the lower 4 bits of the symbol display data are “0100”. It becomes. As a result, symbol display data (“00010100”) composed of 8 digits is generated. When the symbol number is “53H” and the symbol number determines the second special symbol B2, the 14th upper byte data 13 (“00110000”) is selected from the first bit table, and the second bit. The third lower byte data 2 (“00000100”) is selected from the table. In this case, when the upper 4 bits (“0011”) constituting the upper byte data 13 and the upper 4 bits (“0000”) constituting the lower byte data 2 are ORed, the upper 4 bits of the symbol display data are “0011”. " When the lower 4 bits (“0000”) constituting the upper byte data 13 and the lower 4 bits (“0100”) constituting the lower byte data 2 are ORed, the lower 4 bits of the symbol display data are “0100”. It becomes. As a result, symbol display data (“00110100”) composed of 8 digit bits is generated. Thereafter, the main CPU 31a uses the generated symbol display data (that is, data corresponding to the first special symbol B1 or the second special symbol B2) until the main symbol change game is processed. Store in the RAM 31c.

  Next, the main CPU 31a shown in FIGS. 4 and 5 determines the variation pattern based on the determination results of the first big hit determination, the second big hit determination, and the reach determination. Specifically, when the big hit is determined in the first big hit determination and the second big hit determination, the main CPU 31a reads the value of the variation pattern distribution random number from the main RAM 31c, and based on the value, the variation pattern distribution. The variation pattern for the big hit effect is determined from the minute table. When the lose reach is determined in the reach determination, the main CPU 31a reads the value of the fluctuation pattern distribution random number from the main RAM 31c and, based on the value, determines the change pattern for the lose reach production from the change pattern distribution table. decide. Further, when the loss is determined in the reach determination, the main CPU 31a reads the variation pattern distribution random number value from the main RAM 31c, and determines the variation pattern for the loss effect from the variation pattern distribution table based on the value. .

  The display control program is a program for causing the main CPU 31a shown in FIGS. 4 and 5 to function as “display control means”. That is, the main CPU 31a controls the first special symbol display 51 to display the first special symbol B1 based on the generated symbol display data, or the second special symbol display 52 displays the second special symbol B1. Control is performed to display the special symbol B2. More specifically, when the main CPU 31a determines the first special symbol B1 and the variation pattern, the main CPU 31a sets the variation time associated with each variation pattern in the timer storage area of the main RAM 31c as a variation timer (special symbol 1 timer) ( The first special symbol display 51 is caused to start changing the first special symbol B1. Similarly, when determining the second special symbol B2 and the variation pattern, the main CPU 31a sets (stores) the variation time associated with each variation pattern as a variation timer (special symbol 2 timer) in the timer storage area of the main RAM 31c. And the second special symbol display 52 starts to change the second special symbol B2.

  When the main CPU 31a shown in FIGS. 4 and 5 instructs control to the overall control CPU 37a of the overall control board 37, the control command or the like is used as a control signal (8-bit signal), and the signal is output to the output port. 41 and the output buffer 42 at a predetermined timing. Specifically, the main CPU 31a first generates a variation pattern designation command for designating a variation pattern and instructing the start of symbol variation, and sets it as a control command (stored in the main RAM 31c). The control command set here is output in the next and subsequent output processing. Next, the main CPU 31a sets a special symbol designation command for designating the first special symbol B1 or the second special symbol B2 as a control command (stored in the main RAM 31c). The control command set here is output in the next and subsequent output processing. Further, the main CPU 31a subtracts the variation timer set at the beginning of the variation every interrupt (4 ms). When the variation time associated with the variation pattern elapses (when the variation timer reaches 0 ms), the main CPU 31a instructs the symbol stop command (special symbol 1 symbol stop designation command, special symbol) to stop the symbol of each row. 2 design stop designation command) is set (output) as a control command.

  4 and FIG. 5, when the first special symbol B1 is determined at the start of the variation in accordance with the passage of the variation time, the first special symbol B1 is displayed as the first special symbol. The second special symbol B2 is displayed on the second special symbol display 52 if the second special symbol B2 is determined at the start of variation. Specifically, the main CPU 31a, based on the generated symbol display data, the light emitting units 55a to 55h of the first special symbol display 51 or the light emitting units 57a to 57h of the second special symbol display 52. Control to turn on 57h is performed. For example, in the case of symbol display data (“00110100”), the main CPU 31a emits light corresponding to a digit bit whose value is “1”, that is, a light emitting unit 55f (corresponding to a third digit bit (segF). Alternatively, the light emitting unit 57f), the light emitting unit 55e (or light emitting unit 57e) corresponding to the fourth digit bit (segE), and the light emitting unit 55c (or light emitting unit 57c) corresponding to the sixth digit bit (segC) are turned on. Take control. And the 1st special symbol B1 (or 2nd special symbol B2) is comprised by the lighting part of each light emission part 55a-55h (or light emission part 57a-57h).

  The main CPU 31a shown in FIG. 4 and FIG. 5 reads a read signal (INT signal or , The strobe signal) is output via the output port 41 and the output buffer 42.

  When the big hit is determined, the main CPU 31a gives the big hit gaming state. In the big hit gaming state, one opening effect, a plurality of (in this embodiment, any of 2, 8, or 15) round effects and one ending effect are executed. The opening effect is executed when the big winning device 24 is in the closed state and the big hit gaming state is started. Each round effect is executed when the special winning device 24 is switched from the closed state to the open state. The round effect per time is executed between the time when the special winning device 24 is switched to the open state and the switch to the closed state. In addition, the ending effect is when the grand prize winning device 24 is switched from the open state to the closed state, and when the big hit gaming state is finished (in this embodiment, any one of the second, eighth and fifteenth times). At the end of the round production).

Therefore, after the symbol stop command is output, the main CPU 31a shown in FIGS. 4 and 5 generates an opening designation command for instructing the start of the opening effect, and outputs it as a control command. Next, the main CPU 31a outputs a round designation command for instructing start of a round effect as a control command. Specifically, the main CPU 31a determines whether the first big hit symbol random number stored in the random number storage area of the main RAM 31c is any one of “0” to “62” and “142” to “179”. In some cases, the first to fifteenth round designation commands for instructing the start of the first to fifteenth round effects are sequentially output as control commands. Similarly, when the value of the second big hit symbol random number stored in the random number storage area of the main RAM 31c is one of “0” to “73”, “141” to “195”, First to fifteenth round designation commands for instructing the start of the first to fifteenth round effects are sequentially output as control commands. In addition, the main CPU 31a determines whether the first big hit symbol random number stored in the random number storage area of the main RAM 31c is any one of “63” to “105” and “180” to “207”. -The 1st-8th round designation | designated command which instruct | indicates the start of an 8th round production is output in order as a control command. Similarly, when the value of the second big hit symbol random number stored in the random number storage area of the main RAM 31c is any one of “74” to “140”, “196” to “239”, The 1st-8th round designation | designated command which instruct | indicates the start of the 1st-8th round production is output in order as a control command. Further, when the value of the first big hit symbol random number stored in the random number storage area of the main RAM 31c is any one of “106” to “141”, “208” to “239”, the main CPU 31a , The first and second round designation commands for instructing the start of the second round effect are sequentially output as control commands. Thereafter, the main CPU 31a outputs an ending designation command for instructing the start of the ending effect as a control command.
(2-2) Electrical configuration of overall control board 37

  As shown in FIG. 4 and FIG. 5, the overall control board 37 includes an overall control CPU 37a. The general control CPU 37a is electrically connected to an input buffer 43 for inputting control signals and read signals output from the main CPU 31a. Further, an input port 44 is electrically connected to the input buffer 43, and a control signal and a read signal are input to the overall control CPU 37a via the input port 44.

  Further, a general ROM 37b and a general RAM 37c are connected to the general control CPU 37a. The overall control CPU 37a updates the values of various random numbers used for determining the game effect at predetermined intervals. The overall control CPU 37a sets the updated value in the setting area of the overall RAM 37c and rewrites the value before the update. For example, the random number storage area of the overall RAM 37c stores a random number for lost left symbol, a random number for lost symbol, a random number for lost right symbol, and the like.

  By the way, when the variation pattern designation command is input, the overall control CPU 37a shown in FIGS. 4 and 5 stores the variation pattern designated by the variation pattern designation command in the overall RAM 37c. When the special symbol designation command is input, the overall control CPU 37a stores the first special symbol B1 or the second special symbol B2 designated by the special symbol designation command in the overall RAM 37c.

  Furthermore, the overall control CPU 37a, based on the first special symbol B1 stored in the overall RAM 37c, stops the first decorative symbol E1 displayed on the first symbol display unit 61 at the end of the first symbol combination game. Is supposed to generate. For example, when the first special symbol B1 stored in the overall RAM 37c is determined with reference to any of the symbol numbers 0 to 239, the variation pattern stored in the overall RAM 37c is the variation for the big hit effect. It becomes a pattern. In this case, the overall control CPU 37a generates the first decorative symbol E1 (decorative symbol left, middle, right) that is finally stopped by the first symbol display unit 61 so that all the columns have the same type of symbol. More specifically, the overall control CPU 37a generates a decorative symbol left, a decorative symbol right, and a decorative symbol right (each decorative symbol is the same type) based on the first special symbol B1. For example, if the first special symbol B1 is any of “0” to “24”, the first decorative symbol E1 is set to “0”, and the first special symbol B1 is any one of “25” to “49”. For example, the first decorative pattern E1 is set to “1”. The generated first decorative symbol E1 (decorative symbol left, middle, right) is derived as a final symbol combination to the first symbol display unit 61. The overall control CPU 37a stores data corresponding to the generated decorative symbol left, the decorative symbol, and the decorative symbol right in the overall RAM 37c.

  The first decorative symbol E1 generated when the first special symbol B1 is any one of “106” to “141” (when “2R probability variation big hit” is given) is the first special symbol B1. It is the same as the first decorative design E1 generated when the value is any one of “208” to “239” (when “2R normal jackpot” is given). Thereby, even if the player sees the first decorative symbol E1, the player cannot determine whether or not the special symbol probability variation state is given, so the secret mode is set.

  4 and 5, the overall control CPU 37a stops at the second symbol display section 62 at the end of the second symbol combination game based on the second special symbol B2 stored in the overall RAM 37c. The second decorative design E2 to be displayed is generated. For example, when the second special symbol B2 stored in the overall RAM 37c is determined with reference to any of the symbol numbers 0 to 239, the variation pattern stored in the overall RAM 37c is the variation for the big hit effect. It becomes a pattern. In this case, the overall control CPU 37a generates the second decorative symbol E2 (decorative symbol left, middle, right) that is finally stopped by the second symbol display unit 62 so that all the columns are of the same type. Specifically, the overall control CPU 37a generates a decorative symbol left, a decorative symbol in the middle, and a decorative symbol right (each decorative symbol is the same type) based on the second special symbol B2. For example, if the second special symbol B2 is any of “0.” to “24.”, the second decorative symbol E2 is set to “0”, and the second special symbol B2 is “25.” to “49.”. In any case, the second decorative pattern E2 is set to “1”. The generated second decorative symbol E2 (decorative symbol left, middle, right) is derived to the second symbol display unit 62 as a final symbol combination. The overall control CPU 37a stores data corresponding to the generated decorative symbol left, the decorative symbol, and the decorative symbol right in the overall RAM 37c.

  The first special symbol B1 or the second special symbol B2 stored in the general RAM 37c is “−” determined with reference to the symbol number 240, and the variation pattern stored in the general RAM 37c is for lose reach production. 4, the overall control CPU 37 a shown in FIG. 5 determines the loss reach. In this case, the overall control CPU 37a determines the decorative symbols left, middle, and right so that the left column and the right column are the same type of symbols, and the middle column is a different type of symbols from the left and right columns. Specifically, a decorative symbol left and a decorative symbol right (both decorative symbols are of the same type) are generated based on the value of the random symbol for the lost left symbol. Then, the decorative symbol is generated based on the value of the random symbol for the losing symbol. When the value of the random symbol for the losing pattern and the random number value for the losing left symbol (or the value of the random number for the losing right symbol) match, the overall control CPU 37a determines whether the decorative symbol is left in the decorative symbol and the decorative symbol left (or the decorative symbol). The decoration pattern is generated so that (right) does not match. The overall control CPU 37a stores data corresponding to the generated decorative symbol left, the decorative symbol, and the decorative symbol right in the overall RAM 37c. In this embodiment, the numbers that can be taken by the random numbers for the left symbol for lose, the random number for right symbol, and the random number for middle symbol are 10 integers from 0 to 9, and one numerical value corresponds to each type of symbol. It is attached.

  The first special symbol B1 or the second special symbol B2 stored in the overall RAM 37c is “−” determined with reference to the symbol number 240, and the variation pattern stored in the overall RAM 37c is used for producing a loss effect. In the case of the variation pattern, the overall control CPU 37a shown in FIGS. 4 and 5 determines a loss. In this case, the overall control CPU 37a generates decorative symbols left, middle, and right so that all columns do not become the same type of symbols. Specifically, the decorative symbol left is generated based on the value of the random symbol for the lost symbol, the decorative symbol is generated based on the value of the random symbol for the intermediate symbol, and the decorative symbol is generated based on the value of the random number for the lost symbol. Generate the symbol right. In the case where the value of the random symbol for the lost pattern matches the value of the random number for the lost symbol, the overall control CPU 37a generates the decorative symbol right so that the decorative symbol left does not match the decorative symbol right. The overall control CPU 37a stores data corresponding to the generated decorative symbol left, the decorative symbol, and the decorative symbol right in the overall RAM 37c.

  The overall control CPU 37a executes the round promotion effect when the first special symbol B1 stored in the overall RAM 37c is any one of “0” to “62” and “142” to “179”. Take control. Similarly, the overall control CPU 37a promotes a round when the second special symbol B2 stored in the overall RAM 37c is any one of “0.” to “73.”, “141.” to “195.” Control to execute the production. Furthermore, the overall control CPU 37a performs control to execute the probability change notification effect when the first special symbol B1 stored in the overall RAM 37c is any one of “0” to “105”. Similarly, the overall control CPU 37a performs control to execute the probability change notification effect when the second special symbol B2 stored in the overall RAM 37c is any of “0.” to “140.”.

  The overall control CPU 37a shown in FIGS. 4 and 5 uses, as control commands, a change pattern designation command for designating a change pattern stored in the overall RAM 37c, the display control CPU 33a of the display control board 33, and the voice. The sound of the lamp control board 34 is output to the lamp control CPU 34a. As a result, the specific contents of the game effects executed by the display control board 33 and the sound / lamp control board 34 are comprehensively controlled by the overall control board 37.

  Further, the overall control CPU 37a outputs, to the display control CPU 33a, a decorative symbol left designation command for designating the decorative symbol left of the first decorative symbol E1 or the second decorative symbol E2 as a control command. Similarly, the overall control CPU 37a displays an ornament symbol right designation command for designating the ornament symbol right of the first ornament symbol E1 or the second ornament symbol E2, and the ornament symbol of the first ornament symbol E1 or the second ornament symbol E2. The specified design symbol designating command is output to the display control CPU 33a as a control command.

  Thereafter, when the symbol stop command is input from the main CPU 31a, the overall control CPU 37a shown in FIGS. 4 and 5 sends the input symbol stop command to the display control CPU 33a and the sound / lamp control CPU 34a as control commands. Output.

  When the opening designation command is input from the main CPU 31a, the overall control CPU 37a outputs the input opening designation command as a control command to the display control CPU 33a and the sound / lamp control CPU 34a. Next, when any of the first to fifteenth round designation commands, the first to eighth round designation commands, and the first and second round designation commands is input from the main CPU 31a, the overall control CPU 37a The input round designation commands are sequentially output to the display control CPU 33a and the sound / lamp control CPU 34a as control commands. Thereafter, when the ending designation command is input from the main CPU 31a, the overall control CPU 37a outputs the input ending designation command as a control command to the display control CPU 33a and the sound / lamp control CPU 34a.

Note that the overall control CPU 37a shown in FIGS. 4 and 5 uses the control commands and the like as control signals (8-bit signals), and outputs the signals through the output port 45 and the output buffer 46 at a predetermined timing. Further, the overall control CPU 37a, in accordance with the output timing of the control signal, instructs the display control board 33 and the voice / lamp control board 34 to read a control command constituting the control signal (INT signal or , The strobe signal) is output via the output port 45 and the output buffer 46.

The display RAM temporarily stores (sets) various information that can be appropriately rewritten during the operation of the pachinko machine 10.

  The display ROM stores a plurality of types of display effect data used when the first symbol combination game or the second symbol combination game is performed. The display effect data is information for the display control CPU 33a to control the display contents (such as symbol variation) of the first symbol display unit 61 and the second symbol display unit 62, that is, the first symbol display unit 61 and This is information for instructing the second symbol display unit 62 to execute the display effect.

  Further, the display ROM includes one kind of opening effect display effect data, 15 kinds of round effect display effect data, and 1 type used in the big hit gaming state after the first symbol combination game or after the second symbol combination game. Various types of display effect data for ending effects are stored. Display effect data for opening effects is stored in association with the opening effects. Each round effect display effect data is stored in association with each of the first to fifteenth round effects. Each ending effect display effect data is stored in association with the ending effect. Display effect data for opening effects, display effect data for round effects, and display effect data for ending effects are displayed on the first symbol display unit 61 and the second symbol display unit 62 by the display control CPU 33a. This is information for instructing execution of the round effect and the ending effect.

  The display ROM stores promotion effect display effect data used when the round promotion effect is performed, and notification effect display effect data used when the probability change notification effect is performed. The display effect data for promotion effect and the display effect data for notification effect are information for the display control CPU 33a to instruct the first symbol display unit 61 or the second symbol display unit 62 to execute the round promotion effect and the probability change notification effect. It is.

  When the change pattern designation command is input from the overall control CPU 37a shown in FIGS. 4 and 5, the display control CPU 33a stores the change pattern designated by the change pattern designation command in the display RAM. It has become.

  Further, when the decorative design left designation command is input from the overall control CPU 37a, the display control CPU 33a stores the decorative design left designated by the command in the display RAM. Similarly, when the decorative design right designation command is inputted from the overall control CPU 37a, the display control CPU 33a stores the decorative design right designated by the command in the display RAM, and when the decorative design middle designation command is inputted. The decoration pattern designated by the command is stored in the display RAM.

The subroutine of FIG. 13 includes the processes of steps S80 to S83. In step S80, the main CPU 31a determines the lost symbol indicating the loss as the first special symbol B1, and proceeds to the process of step S81.

When the value of the upper digit is less than “15” (step S107: N), the main CPU 31a proceeds to the process of step S109 without performing the process of step S108. On the other hand, when the value of the upper digit is “15” or more (step S107: Y), the main CPU 31a proceeds to the process of step S108. In step S108, the main CPU 31a performs a third change process for further increasing the value of the upper digit by −14, and proceeds to the process of step S109.

  In step S109, the main CPU 31a determines the values of the upper and lower digits (offset values), and proceeds to the process of step S110. In step S110, the main CPU 31a selects, from the first bit table (see FIG. 6A), upper byte data corresponding to the upper digit value constituting the determined symbol number, and proceeds to the processing of step S111. . In step S111, the main CPU 31a selects, from the second bit table (see FIG. 6B), lower byte data corresponding to the lower digit value constituting the determined symbol number, and proceeds to the processing of step S112. To do. In step S112, the main CPU 31a ORs the upper 4 bits constituting the upper byte data and the upper 4 bits constituting the lower byte data, and constitutes the lower 4 bits and the lower byte data constituting the upper byte data. By ORing the lower 4 bits, symbol display data composed of 8 digits is generated. In subsequent step S113, the main CPU 31a stores (sets) the symbol display data generated in step S112 in the main RAM 31c, and proceeds to the processing in step S114.

  In step S114, the main CPU 31a executes a variation pattern determination process. In the variation pattern determination process, the main CPU 31a determines the variation pattern of the second variation game to be executed. Details of the variation pattern determination process will be described later. Thereafter, the main CPU 31a ends this subroutine, and proceeds to the process of step S40 shown in FIG.

  In the process of step S39 (special symbol 2 loss variation setting process), the main CPU 31a executes a subroutine shown in FIG. The subroutine of FIG. 14 includes the processes of steps S90 to S93. In step S90, the main CPU 31a determines the lost symbol indicating the loss as the second special symbol B2, and proceeds to the process of step S91. In step S91, the main CPU 31a stores the lost symbol (second special symbol B2) determined in step S90 in the main RAM 31c as a symbol number. In the present embodiment, a symbol “-” is defined as a lost symbol, and a symbol number 240 indicating the symbol “−” is stored.

  In subsequent step S92, the main CPU 31a acquires the second reach determination random number, performs reach determination for comparing the acquired second reach determination random number and the second reach determination value, and proceeds to the process of step S93. . In subsequent step S93, the main CPU 31a executes a variation pattern determination process. In the variation pattern determination process, the main CPU 31a determines the variation pattern of the second variation game to be executed. Details of the variation pattern determination process will be described later. Then, after step S93 ends, the main CPU 31a ends this subroutine, and proceeds to the process of step S40 shown in FIG.

  In step S40, the main CPU 31a sets (sets) the variation time data corresponding to the variation pattern determined in step S38 or step S39 in the special symbol 2 timer stored in the main RAM 31c, and proceeds to the processing in step S41. To do. In step S41, the main CPU 31a sets a special symbol designation command for designating the second special symbol B2 determined in steps S38 and S39 in the main RAM 31c. Note that the special symbol designation command set in the main RAM 31c in step S41 is output to the overall control CPU 37a of the overall control board 37 by the next and subsequent output processing (not shown). Then, after the end of step S41, the main CPU 31a ends this subroutine, and proceeds to the process of step MC7 in FIG.

  Next, step S61 of the special symbol 1 big hit fluctuation setting process (see FIG. 11), step S114 of the special symbol 2 big hit fluctuation setting process (see FIG. 12), and step S83 of the special symbol 1 loss fluctuation setting process (see FIG. 13). The variation pattern determination process executed in step S93 of the special symbol 2 loss variation setting process (see FIG. 14) will be described.

  In step S70 shown in FIG. 15, the main CPU 31a acquires a variation pattern distribution random number for determining a variation pattern. In the present embodiment, the same variation pattern distribution random numbers are used in the processing related to the first variation game or the second variation game. In step S71, the main CPU 31a determines a variation pattern from the variation pattern distribution table based on the variation pattern distribution random number acquired in step S70.

  In subsequent step S72, the main CPU 31a sets a variation pattern designation command for designating the variation pattern set in step S71 in the main RAM 31c. Further, in step S72, information (flag or the like) corresponding to the fluctuation pattern designation command set in the main RAM 31c, specifically, information indicating that the first special symbol B1 is variably displayed on the first special symbol display 51. Alternatively, information indicating that the second special symbol display 52 is variably displayed on the second special symbol display 52 is set in the main RAM 31c. Note that the variation pattern designation command set in step S72 includes information indicating which of the first symbol display unit 61 and the second symbol display unit 62 is a symbol combination game to be executed. Further, the variation pattern designation command set in the main RAM 31c in step S72 is output to the overall control CPU 37a of the overall control board 37 by the output process from the next time (not shown). Further, when the information indicating that the first special symbol B1 or the second special symbol B2 is variably displayed is set, the main CPU 31a performs the first special symbol B1 or the second special symbol by the output process from the next time (not shown). Variation control for starting variation display of the symbol B2 is executed. Then, the main CPU 31a ends this subroutine.

  In the process of step MC7 (big hit process), the main CPU 31a performs the first big hit determination similar to step S16 shown in FIG. 9 or the second big hit determination similar to step S36 shown in FIG. . When the determination result of the first jackpot determination or the second jackpot determination is not a jackpot, the main CPU 31a proceeds to the process of step MC8. On the other hand, when the determination result of the jackpot determination is a jackpot, the main CPU 31a performs the following processing. That is, the main CPU 31a generates an opening designation command for instructing the start of the opening effect, and outputs it to the overall control CPU 37a of the overall control board 37 as a control command. Next, the main CPU 31a instructs the start of the round effect (one of the first to fifteenth round designation commands, the first to eighth round designation commands, and the first and second round designation commands). Are sequentially output to the overall control CPU 37a as control commands. Thereafter, the main CPU 31a outputs an ending designation command for instructing the start of the ending effect as a control command to the overall control CPU 37a. Then, the main CPU 31a proceeds to the process of step MC8.

  In step MC8, the main CPU 31a stands by until 4 ms elapses after the process of step MC1 is started. After 4 ms elapses, the main CPU 31a proceeds to the process of step MC1 again.

  Therefore, according to the present embodiment, the following effects can be obtained.

  (1) In the pachinko machine 10 of this embodiment, the symbol display data is not stored in the data table in advance, but only when the main CPU 31a determines the symbol number, the main CPU 31a has the upper byte data and the lower byte. It is generated by ORing the data. The upper byte data types are the same 15 types as the upper digit types constituting the symbol number when displayed in hexadecimal, and the lower byte data types constitute the symbol number when displayed in hexadecimal. Therefore, the number of byte data types (31 types) can be made smaller than the number of symbol numbers (240 types). Moreover, the first bit table (see FIG. 6 (a)) and the second bit table (see FIG. 6 (b)) vary the first special symbol B1 and the second special symbol B2. It is a table used in common in both. For this reason, compared with the case where the bit table for 1st special symbol B1 and the bit table for 2nd special symbol B2 are set separately, the kind of byte data can be reduced more reliably. Therefore, even if the types of the first special symbol B1 and the second special symbol B2 are enormous, the data capacity of the program used for generating the symbol display data can be suppressed, and the burden on the main CPU 31a can be reduced. That is, if there are 240 types of symbol display data corresponding to each of the special symbols B1 and B2, 240 bytes of data are required, but only 31 bytes of data (upper byte data and lower byte data) can be used. be able to. In other words, the data capacity of the program for realizing various game characteristics can be increased by the amount of compression of the data capacity of the program necessary for generating the symbol display data, so that the interest of the game is improved.

  (2) For example, it is conceivable to use the generated symbol display data as it is to light the light emitting portions 55c and 57c of the first special symbol display 51 and the light emitting portions 57a to 57h of the second special symbol display 52. However, since the regularity of the lighting methods of the light emitting units 55a to 55h and 57a to 57h is likely to occur, for example, “if a specific light emitting unit is lit, a special symbol regardless of whether other light emitting units are lit or not. There is a possibility that the player will determine that “probability fluctuation is given”.

  Therefore, in the present embodiment, the values of the upper 4 bits constituting the upper byte data 0 to 14 are irregularly arranged in the first bit table, and the lower byte data 0 to 15 are constituted in the second bit table. The lower 4 bits are arranged irregularly. Further, a change process for changing the upper digit value of the symbol number when displayed in hexadecimal is performed, and the symbol display data is generated using the upper digit value obtained as a result of executing the change process. As a result, the generated symbol display data has no regularity, and the lighting modes of the light emitting units 55a to 55h and 57a to 57h have no regularity, so which first special symbol B1 or second special symbol B2 is displayed. If this is the case, it will not be clear whether the special symbol probability variation is given. Thereby, since the player cannot determine the subsequent development based on the first special symbol B1 or the second special symbol B2, the interest of the game is further improved. Since the change process is a relatively simple process, the data capacity of the program for executing the change process (change process execution program) does not have to be very large.

  (3) In this embodiment, since the first symbol combination game by the first ornament symbol E1 and the second symbol combination game by the second ornament symbol E2 are performed, the types of the first special symbol B1 and the second special symbol B2 are changed. Even if the number is not increased, various game characteristics can be realized by the first decorative symbol E1 and the second decorative symbol E2. Accordingly, it is not necessary to increase the types of symbol numbers used for determining the first special symbol B1 and the second special symbol B2, and it is not necessary to increase the types of symbol display data generated based on the symbol numbers. Therefore, the data capacity of the program necessary for generating the symbol display data can be more reliably compressed. Therefore, since the data capacity of the program for realizing various game characteristics can be surely increased by the amount of compression of the data capacity, the interest of the game is further improved.

  (4) In this embodiment, since the first decorative symbol E1 and the second decorative symbol E2 are created not by the main CPU 31a but by the overall control CPU 37a, the burden on the main CPU 31a can be further reduced.

  In addition, you may change this embodiment as follows.

  In the above embodiment, the upper byte data 0 to 14 and the lower byte data 0 to 15 are each composed of upper 4 bits and lower 4 bits. However, it is not always necessary to divide the upper and lower bits into 4 bits. For example, the upper byte data and the lower byte data may be divided into upper 3 bits and lower 5 bits, respectively. Each byte data need not be divided into upper bits and lower bits. For example, each byte data is composed of a first bit consisting of the first digit, the second digit, the fourth digit, and the eighth digit, and a third digit, a fifth digit, a sixth digit, and a seventh digit. It may be divided into the second bit.

  In the above embodiment, when a big hit is determined in the first big hit determination or the second big hit determination, the main CPU 31a and the lower byte selected from the second bit table are selected from the upper byte data selected from the first bit table. Symbol display data was generated by using byte data. On the other hand, when the loss reach or the loss is determined in the first big hit determination or the second big hit determination, the main CPU 31a has uniquely determined the symbol number 240 associated with the symbol display data ("01000000"). . However, even if the loss reach or the loss is determined in the first big hit determination or the second big hit determination, the main CPU 31a determines the byte data from the first bit table and the second bit table, and the symbol display data. May be generated.

  In the change processing execution determination of the above embodiment, the main CPU 31a confirms the value of the eighth digit bit among the eight digits constituting the lower byte data corresponding to the determined symbol number (lower digit value). Was. However, the main CPU 31a may check the value of another bit (for example, the value of the fourth digit to the seventh digit) of the eight digits constituting the lower byte data. Further, the main CPU 31a selects a bit value (for example, the first digit to the fourth digit) out of the eight digits constituting the upper byte data corresponding to the determined symbol number (upper digit value). The digit bit value) may be confirmed.

  -In the change process of the said embodiment, main CPU31a changed the value of the high-order digit which comprises a symbol number. However, the main CPU 31a may change the lower digit value constituting the symbol number, or may change both the upper digit value and the lower digit value constituting the symbol number. Moreover, you may perform a change process by the method different from the said embodiment.

  -The 1st special symbol display 51 of the said embodiment is the light emission part 55a-55g which comprises a 7 segment type display, and the circular light emission part provided in the visible display part of the 1st special symbol display 51 It consisted of 55 hours. Similarly, the second special symbol display 52 of the above embodiment is separately provided from the seven light emitting units 57a to 57g constituting the seven-segment display and the visible display unit of the second special symbol display 52. The star-shaped light emitting portion 57h (light emitting diode) was provided. However, you may change the form of each light emission part 55a-55h and light emission part 57a-57h. For example, all of the light emitting portions 55a to 55h and 57a to 57h may be circular light emitting portions made of light emitting diodes.
