  When a player inserts a banknote into the insertion slot 21, the banknote determination device provided in communication with the insertion slot 21 determines the authenticity and amount of the banknote, and the inserted banknote is a regular banknote. Will accept this bill. When the banknote accepting machine 2 accepts the banknote, a banknote acceptance signal is transmitted to the main game control device 100 via the I / O port 110.

  CPU111 will add the number of credits according to the amount of the accepted bill, and will memorize it in RAM113, if the bill acceptance signal transmitted from bill acceptance machine 2 is received. Further, the CPU 111 outputs a display control signal for adding the display of the balance of the number of credits displayed on the image display device 5 to the LCD control device 150.

  The banknote accepted by the banknote accepting machine 2 is stored in a banknote storage (not shown). Further, the current credit amount is displayed at a predetermined position (for example, upper left) of the main screen 51. A balance display unit composed of a 7-segment LED or a liquid crystal display may be provided, and the current credit number may be displayed on the balance display unit.

  Note that the gaming machine 1 provides a game by accepting a bill, but is not limited to this, and is not limited to a coin, a valuable medium such as a predetermined coin or medal that is given a value capable of executing the game, or a prepaid card. The game may be provided based on the recorded valuable data having a value capable of executing the game.

  Here, the prepaid card is a card on which valuable data is recorded using magnetism, IC (integrated circuit) or the like. In this case, a card unit that communicates with the insertion slot 21 and reads / writes information stored in a prepaid card or the like is provided. The gaming machine 1 may accept the value possessed by the valuable data as a credit by reading out the valuable data stored in the prepaid card by the card unit.

  Further, a game may be provided by using an ID card having a uniquely defined ID number and a server that manages valuable data. In this case, the ID number of the ID card possessed by the player is associated with the valuable data possessed by the player. And the gaming machine 1 has the valuable data by reading the ID number of the ID card inserted into the gaming machine 1 by the player by the card unit and subtracting the valuable value stored in the server corresponding to the ID number. Value may be accepted as credit.

  By operating the game start button 24, the player can execute a game while consuming a predetermined number of credits (for example, 100 yen) corresponding to one game. When the number of remaining credits is less than a predetermined unit, the player cannot execute the game.

  When the game start switch 24A detects an operation of the game start button 24 by the player, a detection signal is output. When the CPU 111 receives the detection signal output from the game start switch 24A via the I / O port 110, the CPU 111 subtracts the credit stored in the RAM 113 by a number corresponding to one game and executes the main game.

  Further, the CPU 111 outputs a display control signal for instructing subtraction of the display of the balance of the credit amount displayed on the image display device 5 to the LCD control device 150.

  In the main game, as shown in FIG. 1, a first character 53 simulating a bullet of a cannon displayed on the upper right portion of the display screen on the main screen 51 is the first simulating a target displayed on the upper left portion of the display screen. A state of flying toward the second character 55 is displayed.

  In the present embodiment, as the main game, a game is executed in which whether or not the first character 53 hits the second character 55 is determined by lottery. When the first character 53 hits the second character 55, the sub game is executed on the sub screen 71.

  The CPU 111 determines whether the game is successful, points are given, or the game is unsuccessful when the player operates the game start button 24 to start execution of the main game, that is, the first character 53 of the cannon bullet. A random number for lottery that determines whether or not the target second character 55 is hit is generated.

  Next, the CPU 111 extracts the generated random number. Then, the CPU 111 compares the extracted random number value with the winning value, and determines whether the random value is a winning value at which the main game is a game success, a point-giving value, or a value that is neither. A lottery to determine is performed. Here, most of the random number values used for the main game lottery are constituted by winning values of the main game success, and the point grant value and the outlier value are extracted with a low probability (for example, 1/40 each). Good.

  Instead of generating the internal lottery random number by software processing executed by the CPU 111, a random number generator for generating a random number is provided in the main game control device 100, and the lottery random number output from the random number generator is used. You may draw lots.

  Further, a predetermined number of points awarded to the player can be exchanged for prizes. Also, points can be used for the main game in the same way as credits.

  Based on the result of the lottery, the CPU 111 controls the execution of the main game displayed on the main screen 51.

  When the result of the main game is a game success, a main display control command signal for instructing an image for producing the main game for displaying an image corresponding to the game success on the image display device 5 is communicated to the LCD control device 150. Sent via port 114.

  When the result of the main game is a game failure, a main display control command signal for instructing an image for producing the main game for displaying an image corresponding to the game failure on the image display device 5 is transmitted to the LCD control device 150. Is done.

  When the result of the main game is point grant, the main display control command signal for instructing an image for producing the main game for displaying the image corresponding to the point grant on the image display device 5 is the LCD control device 150. And points are awarded to the player.

  The image display device 5 displays an image corresponding to the result of the main game lottery based on the main display control command signal.

  Further, the main game control device 100 executes the sub game when the result of the main game is a game success.

  In the sub game, as shown in FIG. 1, an effect of the sub game executed according to the result of the main game is displayed on the sub screen 71. The sub game is a game for determining whether to give a prize to a player.

  In the display areas provided on the left, middle, and right of the variable display area 73 displayed in the sub-screen 71 at the lower center of the display screen of the image display device 5, symbols (for example, “0” to “9”) are displayed. The display of the 12 numbers of symbols by the numbers up to and the English letters “A” and “B”) is changed, and a variable display game as a sub game is performed.

  Then, the gaming machine 1 determines that the success of the main game is detected by the main game control device 100 described later when the determination of the start of the sub game due to the success of the main game is made at a predetermined timing. When the sub game lottery result extracted at the time is a winning value), the sub game has a predetermined combination of symbols (for example, three symbols displayed in the variable display area 73 of the sub screen 71). The game is stopped in the state, that is, the big hit symbol), and the result of the sub game becomes the big hit state.

  Then, the main game control device 100 outputs a payout command signal when the result of the sub game is a big hit. In addition, the result of the sub game is output from the main game control device 100 to the LCD control device 150 via the communication port 114.

  In addition, on the sub screen 71, an image based on the progress of the game (for example, a big hit display which is a display for notifying that the result of the sub game is a big hit, a fanfare display or a sub game which is a display for producing a big hit of the sub game Ending display or the like indicating that the big hit effect is finished and the next sub game is displayed is displayed.

  When the result of the sub game is a big hit state, a prize is awarded to the player. Specifically, prizes such as gift certificates stored in the prize storage are automatically paid out from the payout exit 41 by the prize dispenser 4 that has received the payout command signal from the main game control device 100.

  In the present embodiment, the gaming machine 1 is configured to automatically give out a prize based on the big hit of the sub game. However, the present invention is not limited thereto, and is connected to a prize payout button (not shown) and a prize payout button. The prize payout switch (not shown) is provided in the prize payer 4, and the player waits for detection of a detection signal output from the prize payout switch to detect the operation of the prize payout button. The prize stored in the prize hangar may be paid out from the payout exit according to the acquired specific value.

  In this case, the prize dispenser 4 transmits a prize dispense signal to the main game control device 100 via the I / O port 110, and the CPU 111 receives the prize dispense signal transmitted from the prize dispenser 4 in the RAM 113. A specific valuable value storage area may be provided, and the number of specific valuable values corresponding to the paid out prize may be subtracted from the specific valuable value stored in the specific valuable value storage area. Further, the CPU 111 may output a display control signal for subtracting the display of the balance of the specific value displayed on the image display device 5 to the LCD control device 150.

  In this case, the current specific value may be displayed at a predetermined position (for example, upper right) of the main screen 51. In addition to the image display device 5, a balance display unit composed of a 7-segment LED or a liquid crystal display may be provided, and the current specific value may be displayed on the balance display unit.

  FIG. 4 is a flowchart of main processing according to the first embodiment of this invention. This main process is executed by the CPU 111 provided in the main game control apparatus 100.

  When the power to the gaming machine 1 is turned on, the CPU 111 first executes an initialization process for setting initial values for various control parameters (S101).

  After that, the CPU 111 performs processing such as waveform shaping on the operation signal of the game start button 24 output from the game start switch 24A input via the I / O port 110, the bill acceptance signal from the bill acceptor 2, and the like. The input information is confirmed (S102).

  Thereafter, the CPU 111 outputs data related to the control of the gaming machine to the predetermined output destination via the I / O port 110 (S103).

  For example, the CPU 111 outputs board external information for outputting the state of the gaming machine 1 to the management computer connected via the I / O port 110. The board external information is edited by a main game process (see step S212 in FIG. 5) described later.

  In the external information for the board, whether the game is being executed by the player, whether the main game was successful, whether the sub-game design has been confirmed, whether the sub-game is in a big hit state, the winning probability of the sub-game is temporary The information regarding the progress state of the main game and the sub game, such as whether or not the probability is rising, is included.

  Thereafter, the CPU 111 performs a command transmission process for outputting a control signal described later to the LCD control device 150 and the sub game control device 200 (S104).

  Thereafter, the CPU 111 executes main game processing (S105). The main game process will be described later with reference to FIG.

  Thereafter, the CPU 111 performs error monitoring processing for monitoring abnormalities of various switches and sensors (S106).

  Thereafter, the CPU 111 performs a valuable value acceptance process for adding a valuable value for executing a game in accordance with the insertion of a bill by the player (S107). When a player inserts a banknote from the insertion slot 21 of the banknote receiving machine 2, a banknote determination device (not shown) provided in the banknote receiving machine 2 determines the authenticity and the amount of the inserted banknote. If the bill is authentic, the CPU 111 adds the number of credits stored in the RAM 113 according to the amount of the bill.

  Thereafter, when the CPU 111 detects a prize payout command output based on the sub game jackpot information (see S305 in FIG. 6) indicating the big hit of the sub game executed in the sub game process (see FIG. 8), After awarding a prize, a prize payout process for paying out a predetermined prize (for example, a gift certificate) from the payout opening 41 within the range of the awarded prize is executed (S108).

  Thereafter, the CPU 111 repeats the main process. However, the processes of S101 to S108 are not necessarily executed every time the main process is executed.

  For example, the initialization process (S101) is executed only once immediately after the power is turned on.

  Further, the input process (S102) monitors the input signal every time, but the output process (S103) may be executed every other occurrence of an interrupt. That is, instead of completing all the processes in one interrupt process, the main process may be repeatedly executed a plurality of times to complete a series of game control processes.

  FIG. 5 is a flowchart of the main game process according to the first embodiment of this invention. This main game process is executed by the CPU 111 provided in the main game control device 100.

  First, the CPU 111 determines whether or not the main game is being executed (S201). If the main game is being executed, the process proceeds to step S210. On the other hand, if the main game is not being executed, the process proceeds to step S202.

  If it is determined in step S201 that the main game is not being executed, the CPU 111 determines whether the player has detected a detection signal output from the game start switch 24A that detects the operation of the game start button 24 by the player. It is determined whether or not a game start operation has been performed (S202).

  If it is determined that a game start operation has been performed, the CPU 111 advances the process to step S203. On the other hand, if it is determined that the game start operation has not been performed, the CPU 111 advances the process to step S212. At this time, the gaming machine 1 enters a demonstration display state in which an image indicating that the gaming machine 1 is waiting in a state where a game start operation can be accepted is displayed.

  Thereafter, the CPU 111 determines whether or not the number of credits stored in the RAM 113 is greater than or equal to a predetermined number corresponding to one game (S203). When it is determined that the balance of the number of credits is equal to or greater than a predetermined unit (for example, 100 yen) necessary for executing one game, the CPU 111 corresponds to one game from the number of credits stored in the RAM. The number of credits to be subtracted is subtracted, and the process proceeds to step S204. On the other hand, if it is determined that the credit balance is less than the predetermined unit, the CPU 111 advances the process to step S212.

  Thereafter, the CPU 111 updates the time limit timer and determines whether or not the time limit timer has expired (S204).

  The time limit timer is provided to limit the number of games executed within a predetermined time, and is set in step S205 described later. If it is determined that the time limit timer has expired, the CPU 111 advances the process to step S205. On the other hand, if it is determined that the time limit timer has not expired, the CPU 111 advances the process to step S212.

  Thereby, the execution of the main game is not started until the time limit timer expires.

  For example, if the set time is set to 4 seconds, there will be a gap of 4 seconds or more from the execution of the lottery process (S206) of a main game to the execution of the lottery process of the next main game. Thereby, the number of executions of the main game can be limited to, for example, 15 times or less per minute.

  Therefore, an interval of a certain time or more is ensured from the start of execution of a certain main game to the start of execution of the next main game, and the number of main game executions per unit time is limited.

  Note that the limit on the number of times of execution of the main game per unit time by the time limit timer is not limited to just before the execution of the main game, but may be performed immediately after the execution of the main game or at other timing.

  If the time limit timer has expired, the CPU 111 sets the time limit timer (S205). Thereafter, a lottery process for extracting the main game random number counter value is performed (S206).

  In this lottery process, the CPU 111 extracts the value of the main game random number counter and determines the result of the main game (game success, point grant or game failure) based on the extracted random value.

  If the extracted value of the main game random number counter is a value indicating that the game is successful (winning value), the CPU 111 stores main game winning information in the RAM 113, and this will be described later in step S303 in FIG. Based on the main game winning information, a start signal is output from the main game control device 100 to the sub game control device 200.

  When the extracted value of the main game random number counter is a point grant value, the CPU 111 stores point grant information corresponding to a predetermined number of points (specific value) in the RAM 113. Thereby, in step S306 of FIG. 6 described later, a predetermined number of points are added to the RAM 113, and a predetermined number of points are given to the player.

  Here, the main game random number counter is a counter for generating a random number for determining the result of the main game. The gaming machine 1 includes random number counters such as a main game random number counter and random number counters for imparting randomness to effects or decorations (variable display patterns, stop symbols, etc.) when the main game is advanced. The CPU 111 always performs a process of incrementing the value of each random number counter by one.

  Explaining this process, the process executed by the CPU 111 includes several random number processes. For example, a process of extracting a random number for the lottery to derive the mode of the result of the main game is included. In addition, a process of extracting a random number may be included in order to give randomness to the effect or decoration when the main game is advanced based on the lottery result.

  In this way, the value of the main game random number counter is extracted based on the detection of the signal from the game start switch 24A. The value of the main game random number counter is incremented by 1 in a predetermined range (for example, between 0 and 249) at a predetermined time period (for example, 1 millisecond period), and becomes 0 again when the value exceeds 249. Return processing (random number update processing) is performed.

  Here, the value of the main game random number counter is also agitated when the random number extraction timing is agitated by the detection timing of the signal output from the game start switch 24A.

  As another example of the lottery, the counter value latched at the extraction timing from the high-speed counter by hardware or software may be used as the extracted random number. Further, instead of the high-speed counter, pseudo-random numbers may be generated and used by a multiplication congruential method or a mixed congruential method.

  Then, the CPU 111 is executed depending on whether the random number value of the main game random number counter value extracted in the lottery process in step S206 is a winning value, a point grant value, or a deviation value. The mode of production of the main game is determined (S207).

  Specifically, the CPU 111 confirms the presence / absence of main game winning information stored in the RAM 113, and the result of the main game (game success) prepared in advance in the ROM provided in the gaming microcomputer 301 of the LCD control device 150. , An effect pattern corresponding to point grant or game failure) is selected.

  Thereafter, the CPU 111 sets a main game time timer (S208). The main game time timer is a timer for checking whether or not the time required for producing the main game has elapsed. With the main game time timer, the timing at which the main game effect ends can be known.

  Thereafter, the CPU 111 sets a main display control command signal for effect display of the main game on the image display device 5 (S209).

  Specifically, CPU 111 transmits a control signal edited corresponding to the effect pattern selected in step S207 to LCD control device 150. Thereafter, the process proceeds to step S212.

  If the result of determination in step S201 is that the main game is being executed, the CPU 111 determines whether or not the main game time timer has expired (S210). If the main game time timer has not expired, the process proceeds to step S212. On the other hand, when the main game time timer has expired, the CPU 111 executes award giving process (S211).

  In step S211, when the main game winning information is stored with reference to the RAM 113, the CPU 111 sets a start signal. Based on this start signal, the sub game control device 200 executes the sub game. The start signal will be described in step S304 in FIG. Further, the CPU 111 gives points to the player when the point grant information is stored with reference to the RAM 113.

  In step S212, the CPU 111 executes a process of editing external information related to the main game including information such as whether the game is being executed by the player and whether the main game has been successful (S212). Thereafter, the main game process is terminated.

  FIG. 6 is a flowchart of the award giving process (step S211 in FIG. 5) according to the first embodiment of this invention. The award giving process is executed by the CPU 111 provided in the main game control device 100.

  First, the CPU 111 determines whether or not the lottery result of the main game is a SPIN win (game success) in the lottery process in step S206 of FIG. 5 (S301). If it is determined that the SPIN is not won, the process proceeds to step S305. On the other hand, if it is determined that the SPIN is won, the CPU 111 advances the process to step S302.

  Next, the CPU 111 acquires the delay time of the output of the start signal from the delay time random number counter that generates a numerical string for extracting the random number of the delay time (S302).

  Next, the CPU 111 generates a start signal pattern based on the delay time acquired in step S302, sets the generated start signal in the RAM 113 in order to output it to the sub game control apparatus 200 (S303), The output timing is acquired (S304), and the process proceeds to step S305. The output timing of the start signal will be described later in detail with reference to FIG.

  In step S305, the CPU 111 determines whether or not the result of the main game is point grant in the lottery process in step S206 of FIG. If it is determined that the points are not awarded, the CPU 111 ends the prize giving process and returns to the main game process. On the other hand, if it is determined that points are awarded, the CPU 111 adds a predetermined number of points (specific value) to the RAM 113 (S306). This gives a predetermined number of points to the player. Thereafter, the award giving process is terminated and the process returns to the main game process.

  FIG. 7 is a timing chart of the delay time of the output of the start signal according to the first embodiment of this invention. The start signal of this embodiment is output at a delay timing determined as follows.

  In the present embodiment, the main game is executed with an interval of at least 4 seconds (that is, 4000 milliseconds (hereinafter, ms)). Therefore, the start signal for instructing the sub game control device 200 to execute the main game can theoretically be output at any timing within 4 seconds. That is, the start signal can be delayed for a maximum of 4 seconds.

  The start signal of the present embodiment is output by the main game control device 100 sandwiched between a delay unit and an interval unit whose outputs are both off. The delay unit continues to maintain the signal in the OFF state during the delay time based on the random number value acquired by the random number counter in step S302. The delay time is a time value between 0 ms and 2500 ms, and is determined by a random number acquired from a random number counter.

  The start signal is output as an on-state signal following the delay unit. Upon detecting the rise of this signal, the sub game control device 200 detects a start signal. The start signal functions as a sub game execution signal that instructs the sub game control device 200 to execute the sub game.

  The rise time of the start signal is a time value between 500 ms and 3000 ms, and is determined such that the sum with the delay time is 3000 ms. For example, when the delay time is 2500 ms, the rise time is 500 ms ((A) in FIG. 7). When the delay time is 500 ms, the rise time is 2500 ms ((B) in FIG. 7). In the start signal, the ON state is maintained until this rise time elapses.

  The interval part is a redundant part provided to prevent continuous start signals from being combined. The interval time is a constant time value such as 1000 ms, for example.

  Thus, since the start signal having the rising portion is delayed by the delay time generated by the random number counter, the timing at which the sub game control device 200 detects the rising of the start signal can be changed at random.

  A start signal is generated each time from the determined delay time and rise time, but multiple types of start signals with different delay times and rise times are prepared in advance (for example, time values of delay time and rise time) 300 types of different start signals), and one start signal may be selected based on the extracted random number counter value.

  FIG. 8 is a flowchart of the sub-game control process for game control according to the first embodiment of this invention. This sub game control process is executed by the game microcomputer 201 provided in the sub game control device 200.

  After power is turned on to the gaming machine 1, this sub game control process is repeatedly executed at a predetermined time period (for example, every 1 millisecond). The processes of S601 to S607 are not necessarily performed every time the sub game control process is executed.

  For example, the input process (S601) monitors the input signal every time, but the output process (S602) may be executed every other execution of the sub game control process. That is, instead of completing all the processes in one execution of the sub game control process, the sub game control process may be repeatedly executed a plurality of times to complete a series of processes.

  First, the gaming microcomputer 201 performs processing such as waveform shaping on the start signal, count signal, etc. output from the main game control device 100 input via the input interface 202, and determines the input information (S601). .

  Thereafter, the gaming microcomputer 201 outputs data relating to game control such as a special prize signal to a predetermined output destination (main game control device 100, management computer, etc.) via the output interface 203 (S602).

  For example, the gaming microcomputer 201 outputs board external information for outputting the state of the gaming machine 1 to the management computer connected via the external communication terminal 204. The board external information is edited by a sub game process (see S1311 in FIG. 12) described later.

  Thereafter, the gaming microcomputer 201 performs a command transmission process for outputting a control signal to be described later to the sub-display control device 250 (S603).

  After that, the gaming microcomputer 201 uses each random number counter such as a subgame random number counter for determining whether or not the subgame (variable display game) is won, and effects or decorations when the subgame is advanced (variable display pattern). And random number update processing for incrementing the value of each random number counter for imparting randomness to each other (S604).

  Thereafter, the gaming microcomputer 201 performs an error monitoring process for monitoring whether there is no fraud or whether the sub game is being executed normally in relation to the execution of the sub game (S605). This error monitoring process will be described later with reference to FIG.

  Thereafter, the gaming microcomputer 201 detects the presence or absence of input of a start signal, a count signal, and the like output from the main game control device 100, and updates the count number of the sub game start memory according to the result. Processing is performed (S606).

  When the start signal is detected in the input determination process, if the maximum number (for example, 4) of sub game start memories is not stored, the gaming microcomputer 201 generates the game in step S505 based on the start signal. With reference to the sub game random number counter value, one new sub game random number counter value is added and stored as a sub game start memory, and the current sub game start memory number is incremented by 1 and updated.

  On the other hand, when the sub game start memory is stored up to the maximum number, the gaming microcomputer 201 does not store the sub game random number counter value based on the start signal and does not update the sub game start memory number.

  When the count signal is detected in the input determination process, the gaming microcomputer 201 adds 1 to the count storage number that is the cumulative value of the detected number of count signals in the current big hit state based on the count signal. And update.

  Thereafter, a sub game process (S607) for controlling the progress of the sub game is executed.

  As described above, in the sub game process, when the execution result of the main game is a game success, the gaming microcomputer 201 starts the sub game based on the detection of the start signal transmitted from the main game control device 100. It is determined whether or not the sub game random number counter value (random number related to the result of the sub game extracted and stored in step S607) stored as memory is hit, and a process of changing the display of the symbol displayed on the sub LCD 5b is performed.

  If the sub-game random number counter value stored in the sub-game start memory is a winning value, the symbol that is changed and displayed (variably displayed) in the sub-game stops at the winning symbol, and a big hit state related to the sub-game is entered. Further, when the big hit state is reached, a special prize signal is transmitted to the main game control device 100, and a predetermined prize is given to the player. Thereafter, the sub game control process is terminated and the process returns to the main process.

  It should be noted that the start signal is subjected to chattering removal in the input process (S601), the input signal level is confirmed, the level change of the input signal is monitored, and if a rising edge is detected, detection information of the rising edge is detected. Stored together with input signal level information. Therefore, the delay time becomes a time lag, and the rising edge is stored in the input process (S601).

  Then, in the input determination process (S606), it is determined whether or not the rising edge of the start signal is stored. If there is a rising edge stored, the start storing process is executed at this timing, and the rising edge storage is erased. Therefore, the sub game random number counter value is extracted and stored at a timing reflecting the time lag based on the delay time.

  FIG. 9 is a flowchart of the discharge command signal set process according to the first embodiment of this invention. The discharge command signal setting process is one of the input determination processes (S606) of the sub game control process of FIG. 8, and is executed by the game microcomputer 201 included in the sub game control apparatus 200.

  First, the gaming microcomputer 201 determines whether or not a start signal output from the main gaming control device 100 has been detected (S701). If no detection signal is input, the gaming microcomputer 201 ends the discharge command signal setting process.

  On the other hand, when there is an input of a detection signal, data for a predetermined number of winning balls corresponding to the input start signal is acquired (S702), and a discharge command signal including the acquired data for the number of winning balls is used as the main. In order to output to the game control device 100, the game microcomputer 201 is set in the RAM (S703), and then the discharge command signal setting process is terminated.

  Note that the discharge command signal is output to the main game control apparatus 100 in the command transmission process of step S603. Here, as described above, the command transmission process (S603) of the sub game control process is not necessarily performed every time the sub game control process is executed. When the command transmission process is executed every other execution of the sub game control process and the time required for one execution of the sub game control process is 4 ms, for example, the processing time of the other process If the sub game control device 200 detects the start signal, about 4 ms after the start signal is detected (when the command transmission process is executed when the next sub game control process is executed) or about 8 ms after (the next sub game When the command transmission process is not executed when the control process is executed). Therefore, when the main game control device 100 detects the discharge command signal, it may be detected by providing a certain allowable range, for example, 4 ms to 8 ms.

  Note that the time from the detection of the start signal to the execution of the command transmission process varies randomly within a certain allowable range.

  FIG. 10 is a timing chart of the discharge command signal according to the first embodiment of this invention. The discharge command command is a signal output from the sub game control device 200 toward the main game control device 100.

  The discharge command command uses a total of five signal lines including one control signal line (BSTB) and four parallel data signal lines (BD0 to BD3). As shown in FIG. 10, the discharge command command is composed of two parts, a first command and a second command. The first command is negative logic, and commands the timing to detect the parallel data signal at the rising timing of BSTB. The second command is positive logic and commands the timing for detecting the parallel data signal at the falling timing of BSTB.

  The first command includes an off state that takes a time value in the range of 10 μs to 25 μs and an on state that takes a time value of 25 μs to 40 μs. The second command includes an on state that takes a time value in the range of 10 μs to 25 μs and an off state that takes a time value of 25 μs to 40 μs. Although the time value of each state of the first command and the second command varies within the allowable range described above, it is sufficiently smaller than 0 to 2500 ms of the delay time of the start signal, so that the game machine 1 can execute the game. There is almost no direct effect.

  FIG. 11 is a flowchart of the error monitoring process (step S106 in FIG. 4) according to the first embodiment of this invention. The error monitoring process is executed by the CPU 111 provided in the main game control device 100.

  First, the CPU 111 determines whether or not a discharge command signal output from the sub game control device 200 is detected based on the start signal (S801). If it is determined that the discharge command signal is not detected, the process proceeds to step S805. On the other hand, if it is determined that the discharge command signal is detected, the CPU 111 advances the process to step S802.

  Next, CPU111 acquires the timing which received the discharge command signal (S802). Next, the CPU 111 acquires the timing at which the start signal acquired in step S3024 of the award grant process is output (S803), compares the timing at which the discharge command signal is received with the timing at which the start signal is output (S804), and step The process proceeds to S805.

  In step S805, the CPU 111 determines whether the result of the timing comparison in step S804 is abnormal. Since it is normal that the time lag of both timings falls within a predetermined time value (for example, within 12 ms), it is possible to determine that the time lag outside this range (error time allowable range) is abnormal.

  Further, since the time lag changes randomly from the relationship between the input processing time and each processing time, it is possible to determine that the time lag is abnormal even when the time lag continues to take a constant value. It can be considered that an illegal response signal is input due to an illegal operation.

  It should be noted that an abnormality can also be determined when there is a start signal output timing at which the comparison between the discharge command signal reception timing and the start signal output timing is not performed for a long time. If the comparison result is normal, the CPU 111 ends the error monitoring process and returns to the main process. On the other hand, when the comparison result is abnormal, the CPU 111 executes an abnormality notification process (S806).

  Specifically, the CPU 111 transmits a main display control signal for notifying abnormality to the LCD control device 150. The LCD control device 150 causes the image display device 5 to display a notification image that notifies the abnormal state. As a result, the main game control device 100 that is originally connected is illegal, such as remodeling or replacement, or between the main control device 100 and the sub game control device 200 (for example, the relay board 300) or the connector connection portion of each control device. The manager of the gaming machine 1 and the player are notified that there is a possibility that an illegal work such as an illegal part is attached to the game machine 1 or the like.

  In addition, the CPU 111 turns on a pilot lamp (not shown) provided in the decoration portion 8 at the upper front of the gaming machine 1 so that the main game control device 100 that is originally connected is altered or replaced, or the main There is a possibility that fraudulent work may have been performed such as unauthorized parts being attached between the control device 100 and the sub game control device 200 (for example, the relay board 300) or a connector connection portion of each control device. The administrator of the gaming machine 1 and the player may be notified.

  Further, the main game control device 100 transmits a control signal notifying the sub game control device 200 of the abnormality, and the sub game control device 200 notifies the abnormality to the management computer and the abnormality notification device connected to the gaming machine 1. May be transmitted to notify the administrator of the gaming machine 1 of the abnormality.

  Thereafter, the CPU 111 ends the error monitoring process and returns to the main process.

  FIG. 12 is a flowchart of sub game processing according to the first embodiment of this invention. This sub game process is executed by the game microcomputer 201 provided in the sub game control device 200.

  First, the gaming microcomputer 201 determines whether or not a sub game is being executed (S1301). If the sub game is being executed, the process proceeds to step S1308. On the other hand, if the sub game is not being executed, the process proceeds to step S1302.

  When it is determined in step S1301 that the sub game is not being executed, the gaming microcomputer 201 determines whether or not the gaming state of the sub game is a special prize state (S1302). In step S1309, which will be described later, the gaming state of the sub game is set to either the special prize state or the normal state based on the sub game jackpot information stored based on the execution result of the sub game.

  If it is determined that the game is not in the special prize state, the gaming microcomputer 201 advances the process to step S1304. On the other hand, if it is determined that the game is in the special prize state, the gaming microcomputer 201 executes a special prize process (S1303), and the process proceeds to step S1310.

  In this special award process, a prize payout command is set based on the sub game jackpot information stored in the RAM provided in the gaming microcomputer 201. Thereby, the prize is paid out from the prize dispenser 4 in step S108 of FIG. In addition, the prize is not directly paid based on the sub-game jackpot information, but points that allow the prize to be paid out with a certain value (eg, 500 points) greater than a certain value based on the sub-game jackpot information. May be.

  Thereafter, the gaming microcomputer 201 determines whether or not the number of start memories stored in the RAM included in the gaming microcomputer 201 is 1 or more (S1304). If the start memory is less than 1, the gaming microcomputer 201 determines that the start memory is not stored, and proceeds to step S310. On the other hand, if the number of stored start memories is 1 or more, the game microcomputer 201 stores the start memory, and advances the process to step S1305.

  In step S1305, the gaming microcomputer 201 determines whether or not the oldest value in the starting memory stored in the RAM provided in the gaming microcomputer 201 is the winning value of the sub game, and is stored in the RAM. Subtract 1 from the starting memory number. When the value of the start memory is a big hit value, the gaming microcomputer 201 erases the start memory and stores the sub game big hit information in the RAM. On the other hand, when the value of the start memory is not a big hit value, the gaming microcomputer 201 erases the stored sub game big hit information when the sub game big hit information is stored in the RAM.

  In the determination process of step S1305, the gaming microcomputer 201 extracts the value of the sub game random number counter stored as the start memory, and based on the extracted random value, the result of the sub game (big hit or miss) is obtained. decide.

  Here, the sub game random number counter is a counter for generating a random number for determining the result of the sub game. The gaming machine 1 provides randomness to each random number counter such as a main game random number counter and a sub game random number counter and effects or decorations (variable display patterns, stop patterns, etc.) when the main game and sub game are advanced. Each random number counter is provided. The gaming microcomputer 201 always performs a process of incrementing the value of each random number counter by one.

  The lottery for determining the sub game will be described. The processing executed by the gaming microcomputer 201 includes some random number processing. For example, a process of extracting a random number for a lottery for deriving an aspect of the result of the sub game is included. In addition, a process of extracting a random number may be included in order to impart randomness to the effect or decoration when the sub game is advanced based on the lottery result.

  As an example of these lottery processes, the value of the counter is incremented by 1 in a predetermined time period (for example, 1 millisecond period) between 0 and 249, and is returned to 0 again when the value exceeds 249. There is.

  This counter value is extracted when the gaming microcomputer 201 determines that the start signal output by the main game control device 100 is detected.

  Similar to the value of the main game random number counter, the value of the sub game random number counter is incremented by 1 within a predetermined range (for example, between 0 and 249) at a predetermined time period (for example, 1 millisecond period). When the value exceeds 249, a process of returning to 0 again (random number update process) is performed.

  However, random numbers depend on the randomness of the random number extraction timing, and if the above processing is repeated, the random number values extracted at a cycle of 250 milliseconds will be the same value, reducing the randomness. To do. The result of the sub-game lottery is required to be fairer in order to determine the result of the sub-game to which the prize is given. Therefore, updating of the counter game random number counter value is provided separately. The first random number update process is executed using the first random number counter, and the counter value of the second random number update process using the sub game random number counter is calculated based on the random number value extracted from the first random number counter. Further randomness is imparted by stirring.

  Instead of starting the update of the counter value of the sub-game random number counter of the second random number update process in the above-described example from 0 every time, the value obtained in the first random number update process is used as the counter of the second random number update process. The value is updated as the initial value of the value, and when the counter of the second random number update process makes one round and the update is completed, the new value obtained by the first random number update process is updated to the next second random number update process. Set as the initial value of the counter.

  In this way, the initial value when the counter value is changed in the second random number update process is updated one after another. Note that the random number update period in the first random number update process is different from the random number update period in the second random number update process, so the randomness of the counter described above can be increased.

  As another example of the lottery, a counter value latched at the extraction timing from a high-speed counter by hardware or software may be used as the extracted random number. Further, instead of the high-speed counter, pseudo-random numbers may be generated and used by a multiplication congruential method or a mixed congruential method.

  In the lottery process (FIG. 5) in step S206, when the result of the main game is a game success and the start signal output by the main game control device 100 is detected, the sub game start memory is up to the maximum number (for example, 4). When not stored, the gaming microcomputer 201 refers to a subgame random number counter value to be described later based on detection of the start signal, and newly sets the subgame random number counter value as a subgame start storage. Add and store it, and update it by adding 1 to the current number of subgame starts.

  On the other hand, when the sub game start memory is stored up to the maximum number, the gaming microcomputer 201 does not store the sub game random number counter value based on the start signal and does not update the sub game start memory number.

  Here, the sub game random number counter is a counter for generating a random number for determining the result of the sub game. The gaming machine 1 provides randomness to each random number counter such as a subgame random number counter for determining whether or not the subgame is won and effects or decorations (variable display patterns, stop symbols, etc.) when the subgame is advanced. Each random number counter for providing is provided. The gaming microcomputer 201 always performs a process of incrementing the value of each random number counter by one.

  Next, the gaming microcomputer 201 executes the effect of the sub game to be executed depending on whether the value of the sub game start storage extracted in the determination process of step S1305 is a big hit value or a loss value. An aspect is determined (S1306).

  Thereafter, the gaming microcomputer 201 sets a sub game time timer (S1307). The sub game time timer is a timer for checking whether or not the time required for producing the sub game has elapsed. With the sub game time timer, it is possible to know the timing at which the effect of the sub game ends.

  If the result of determination in step S1301 is that the main game is being executed, the gaming microcomputer 201 determines whether or not the sub game time timer has expired (S1308). If the sub game time timer has not expired, the process proceeds to step S1311. On the other hand, if the sub game time timer has expired, the gaming microcomputer 201 executes a gaming state transition process (S1309).

  In step S1309, if the result of the determination process in step S1305 is a big hit, the gaming microcomputer 201 stores the subgame big hit information in the RAM provided in the gaming microcomputer 201. Based on the sub game jackpot information, the game state of the sub game is set to the special prize state or to the normal state.

  In step S1310, the gaming microcomputer 201 sets a slave display control command signal for effect display of the sub game on the image display device 5.

  Specifically, the gaming microcomputer 201 is prepared in advance in the image ROM 257 provided in the sub display control device 250 by confirming the presence / absence of sub game jackpot information stored in the RAM provided in the gaming microcomputer 201. An effect pattern corresponding to the result of the sub-game (big hit or miss) is selected. Thereafter, the gaming microcomputer 201 transmits a control signal edited in accordance with the selected effect pattern to the sub-display control device 250. Thereafter, the process proceeds to step S1311.

  After that, the gaming microcomputer 201 includes information such as whether the symbol of the sub game is confirmed, whether the sub game is a big hit state, whether the winning probability of the sub game is temporarily changing, or the like. Processing for editing external information related to the subgame is executed (S1311). Thereafter, the main game process is terminated.

  Thus, the sub game control device 200 functions as a slave game control device.

  FIG. 13 is a flowchart of the game display control process according to the first embodiment of this invention. The game display control process is a display control process for the main game and the sub game, but the same process is separately executed for the main game and the sub game. The game display control process of the sub game is executed by the game microcomputer 251 provided in the sub display control device 250. The game display control process for the main game is executed by the CPU 161 provided in the LCD control device 150. Here, the display control process for the sub game will be described based on FIG. 13 and the description for the display control process for the main game will be omitted. In the present embodiment, the same process is also performed for the display control process for the main game. Is executed by the main display control processor 350.

  First, when the gaming microcomputer 251 receives the slave display control command signal transmitted from the sub game control device 200, the gaming microcomputer 251 performs reception data analysis processing for developing a display control sequence from the received slave display control command signal (S1701). ).

  The display control sequence is display control procedure information for instructing display control contents in time series.

  Then, the gaming microcomputer 251 generates a display control sequence based on the command analysis result of the slave display control command signal in step S1701 (S1702). The display control sequence is display control data that defines how display contents are controlled according to the elapsed time of display.

  Thereafter, the gaming microcomputer 251 follows the generated display control sequence to display character data (for example, character data represented as sprite data having a predetermined pixel size) or attribute data (character data to be displayed). Enlarging / reducing, moving direction / moving speed, and data for designating which one is to be displayed on the front side when a plurality of characters are overlapped, transparency, etc. are determined.

  Thereafter, the gaming microcomputer 251 performs a data transfer process for transferring display data and attribute data to the GDP 256 (S1703).

  The GDP 256 receives the transferred data and expands the image data in a frame buffer provided in the GDP 256.

  Thereafter, the gaming microcomputer 251 waits until the vertical synchronization flag is set and adjusts the timing (S1704).

  Thereafter, when a vertical synchronization signal is transmitted from the LCD controller 150 and the vertical synchronization flag is set, the gaming microcomputer 251 transmits a drawing command to the GDP 256 (S1705). The GDP 256 receives this drawing command and outputs the display image data stored in the frame buffer to the LCD control device 150.

  Thereafter, the gaming microcomputer 251 clears the vertical synchronization flag, and then ends the sub game display control process.

  Thus, in order to synthesize the information of two systems with different paths and display the image on the image display device 5, when an illegal act is performed, the images displayed on the image display device 5 do not match, Since a contradiction occurs, fraud can be easily detected.

  In addition, since the route for determining each display content is different between the route of the LCD control device 150 and the route of the sub display control device 250, it is difficult to perform unauthorized manipulation so that the two match.

  As described above, according to the first embodiment of the present invention, it can be excluded that the game execution timing has periodicity by the wait time set to suppress the gambling of the gaming machine. Further, the shortest wait time can be reliably guaranteed as compared with the case where the wait time is set at random.

  In addition, by setting an upper limit of the wait time, the wait time does not take too long, so that unnecessary stress can be prevented from being applied to the player's game progress.

  In addition, it is possible to eliminate illegal games by detecting illegalities that illegally adjust a start signal output timing to illegally win a prize.

(Second Embodiment)
In the second embodiment, the relay board 300 includes a gaming microcomputer 301, an input interface 302, and an output interface 303. The relay board 300 randomly inputs a start signal after a process for delaying the start signal and a discharge command. The difference is that fraud is determined according to the delay time until the response of the signal.

  In addition, the same code | symbol is attached | subjected to the structure same as 1st Embodiment, and the description is abbreviate | omitted.

  FIG. 14 is a block diagram of a relay board 300 according to the second embodiment of this invention.

  The relay board 300 of the present embodiment relays signal transmission / reception between the respective control devices provided in the gaming machine 1 and auxiliaryly controls games executed in the gaming machine 1. The relay board 300 includes a gaming microcomputer 301, an input interface 302, an output interface 303, and an external communication terminal 304. The relay board 300 functions as a relay device.

  The gaming microcomputer 301 includes a CPU that controls the start signal delay processing of the relay board 300, a ROM that stores invariant information for controlling the processing, and a RAM that is used as a work area when controlling the processing. Prepare. Further, the gaming microcomputer 301 is a one-chip microcomputer in which a CPU, a ROM, and a RAM are housed in one IC package.

  An identification number uniquely set in the gaming microcomputer 301 can be output from the external communication terminal 304, and an inspection device or a management computer (so-called hall control) is connected to the external communication terminal 304. be able to.

  The inspection device can detect an illegal act such as replacement or modification of the gaming microcomputer 301 based on the identification number of the gaming microcomputer 301. The management computer can identify the gaming machine by the identification number of the gaming microcomputer 301.

  When the game microcomputer 301 receives the start signal output from the main game control device 100 via the input interface 302, the game microcomputer 301 receives the delayed start signal obtained by delaying the start signal via the output interface 303. Output to 200. When the game microcomputer 301 receives the count signal output from the main game control device 100 via the input interface 302, the game microcomputer 301 outputs the count signal to the sub game control device 200 via the output interface 303.

  In addition, when the gaming microcomputer 301 receives the special prize signal output from the sub game control apparatus 200 via the input interface 302, it outputs the special prize signal to the main gaming control apparatus 100 via the output interface 303.

  In addition, when the gaming microcomputer 301 receives the discharge command signal output from the sub game control apparatus 200 via the input interface 302, the gaming microcomputer 301 depends on a delay time from receiving the start signal to receiving the discharge command signal. It is determined whether there is an abnormality, and if it is determined that there is an abnormality, an abnormality signal is output to the main game control device 100 via the output interface 303.

  The relay board 300 relays a signal for transmitting / receiving a video signal or the like for displaying a display image of the sub game. Note that the relay substrate 300 may be provided with a photocoupler that removes noise from each signal and shapes the waveform of the signal.

  Here, the operation of the relay substrate 300 will be described.

  First, start signal delay processing by the relay substrate 300 will be described. The game microcomputer 301 of the relay board 300 that has received the start signal output from the main game control device 100 executes processes corresponding to the processes of steps S302 to S304 of the award grant process of FIG. 6 in the first embodiment. To do. Specifically, the gaming microcomputer 301 determines the delay time of the start signal by a random number counter, determines and sets the output timing of the start signal (FIG. 7) based on this delay time, and the start signal at this time The delay time is stored.

  Next, abnormality detection and notification processing by the relay substrate 300 will be described. The game microcomputer 301 of the relay board 300 that has received the discharge command signal output from the sub game control device 200 executes a process corresponding to the error monitoring process of FIG. 11 in the first embodiment. Specifically, when the gaming microcomputer 301 detects the discharge command signal, the gaming microcomputer 301 acquires the timing at which the discharge command signal is received, and outputs the timing at which the start signal corresponding to the discharge command signal held in advance is output. If it is acquired and the timings of both are compared and abnormal, a process of notifying the abnormality is performed.

  Here, if the gaming microcomputer 301 determines that the delay time from receiving the start signal to receiving the discharge command signal is abnormal, the gaming microcomputer 301 sends the abnormal signal to the main game control device via the output interface 303. Output to 100.

  When the gaming control device 100 receives the abnormality signal, the CPU 111 turns on a pilot lamp (not shown) provided in the decoration portion 8 at the upper front of the gaming machine 1 by a control signal notifying the abnormality, or The abnormality information is output to a management device that manages the gaming machines in the game hall, and the manager of the gaming machine 1 and the player are notified that an abnormality has occurred in the gaming machine 1. In addition, the CPU 111 transmits a main display control signal for notifying abnormality to the LCD control device 150. The LCD control device 150 displays a specific notification image on the image display device 5. As a result, the manager of the gaming machine 1 and the player are notified that an abnormality has occurred in the gaming machine 1.

  Note that the relay board 300 may send a signal notifying the abnormality to the management computer or abnormality notification device connected to the gaming machine 1 to notify the administrator of the gaming machine 1 of the abnormality.

  The abnormality signal may be output to an inspection apparatus or a management computer (so-called hall control) via the external communication terminal 304 provided in the relay board 300 to notify the abnormality. Thereby, for example, even if there is an act of obstructing detection or notification of an abnormal signal due to, for example, an illegal work on the main game control device 100, an abnormality can be notified to a game hall manager or the like.

  In addition, when the relay board 300 detects an abnormality, the abnormality notification may be performed, or the communication relay between the main game control device 100 and the sub game control device 200 may be stopped in place of the abnormality notification. . As a result, it is possible to quickly stop an abnormal game due to unauthorized manipulation and prevent the damage from spreading.

  As described above, according to the second embodiment of the present invention, in addition to the effects of the first embodiment described above, the relay board 300 includes the gaming microcomputer 301 and performs start signal delay and abnormality determination. Since it is a structure, since the structure is divided | segmented for every function, the versatility of each structure increases and it is economical.

(Third embodiment)
In the third embodiment, the randomness of the delay time of the start signal is obtained by the delay time update process executed as a subroutine in the delay time acquisition in step S302 of the prize award process (FIG. 6) of the first embodiment. The point that is raising is different.

  In addition, the same code | symbol is attached | subjected to the structure same as 1st Embodiment, and the description is abbreviate | omitted.

  FIG. 15 is a flowchart of delay time update processing according to the third embodiment of this invention.

  In the third embodiment, the random number counter of the delay time of the start signal is further stirred by the delay time update process shown in FIG.

  This delay time update process is executed by the CPU 111 provided in the main game control apparatus 100.

  First, the CPU 111 determines whether or not a game start operation is detected by the game start switch 24A (S2001). When the game start operation is detected, the CPU 111 acquires the counter value of the random number counter at the timing when the output signal output from the game start switch 24A is detected (S2002), and advances the process to step S2005. On the other hand, if a game start operation has not been detected, the process proceeds to step S2003.

  In step S2003, the CPU 111 determines whether or not a discharge command signal output from the sub game control apparatus 200 has been detected. When the discharge command signal is detected, the CPU 111 acquires the counter value of the random number counter at the timing when the discharge command signal is detected (S2004), and the process proceeds to step S2005. On the other hand, if the discharge command signal is not detected, the process proceeds to step S2006.

  In step S2005, the CPU 111 agitates the delay time random number counter based on the counter value acquired in step 2002 or step S2003. That is, the delay time random number counter is acquired after adding the acquired counter value to the counter value of the delay time random number counter at that time in the process of step S2005 and then performing the upper limit correction process. Counting of the counter value of the delay time random number counter is newly started from the counter value. Thereafter, the process proceeds to step S2006. The agitation of the counter value is not limited to the addition by the acquired counter value, and may be other arithmetic processing, replacement processing, or the like.

  In step S2006, the CPU 111 adds 1 to the delay time random number counter value, and then returns to delay time acquisition in step S302 of the awarding process.

  As described above, according to the second embodiment of the present invention, in addition to the effects of the first embodiment described above, the delay time is set based on the timing of the game start operation by the player, which is an external factor. Since the stirring is performed, it is possible to further eliminate the randomness of the random number, and it is possible to secure a more fair game.

  The embodiments disclosed herein are illustrative and non-restrictive in every respect. The scope of the present invention is defined by the terms of the claims, rather than the description of the invention described above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  Moreover, the following are typical examples of aspects of the present invention other than those described in the claims.

The slave game execution signal is transmitted by one-way communication from the master game control device to the slave game control device.
The response signal is transmitted by one-way communication from the slave game control device to the main game control device.
A gaming machine in which signals are transmitted through physically different communication lines.

  According to this configuration, since the communication lines of the slave game execution signal (start signal) and the response signal (discharge command signal) are physically separated and the path is different, fraud can be easily detected, and further illegal acts It becomes difficult. As a result, a gaming machine in which a fair game is secured by eliminating fraud is provided.
