Description

  The present invention relates to a ball game machine such as a pachinko machine or an arrangement ball machine, and more specifically, a symbol display means for variably displaying one or a plurality of game symbols, and a variation display of a game symbol by the symbol display means is started. A main control board for selecting a variation pattern and a stop symbol used for the variation from a plurality of types and transmitting at least a variation pattern command for designating the variation pattern and a stop symbol command for designating the stop symbol; A ball game including a symbol control board having a symbol control means for controlling a variation display of a game symbol by the symbol display means based on the fluctuation pattern command and the stop symbol command transmitted from the main control board side Related to the machine.

  In a ball game machine such as a pachinko machine, for example, a game symbol is variably displayed on a symbol display means such as a liquid crystal display means on the basis of detection of a game ball by a symbol starter, for example, a stop symbol after the change is displayed in advance. The mainstream is one that is configured to generate a profitable state that is advantageous to the player, such as opening the big winning means when the specific mode is set.

  In this type of ball game machine, a sub-control board (symbol control board) for controlling the symbol display means is provided separately from the main control board. Select the variation pattern and stop symbol on the side, and send the variation pattern command and stop symbol command to specify the selected variation pattern and stop symbol, respectively, to the symbol control board side, and receive the command The control board side controls the symbol variation by the symbol display means based on these commands.

  By the way, in the ball game machine having such a configuration, for example, an abnormality occurs in command communication from the main control board side to the symbol control board side due to the influence of noise or the like, and a fluctuation pattern command or If a stop symbol command is missed, the symbol variation display corresponding to that command cannot be performed normally, and further, the game is stopped and reset to return the display effect after that to normal. There are cases where it must be done.

  Therefore, for example, in the pachinko machine described in Patent Document 1, in order to minimize the influence on the game when an abnormality occurs in the command communication related to the symbol control, if there is a missed command on the symbol control board side, The following processing is performed. That is, when at least one of the stop symbol commands is missed on the symbol control board side, for example, until the temporary stop using the stop symbol command received last time (used in the previous symbol fluctuation) instead of the missed command A symbol change is performed, and a stop symbol corresponding to the stop symbol command that was missed at the time of the final stop is displayed by, for example, “×”.

For example, when a variation pattern command is missed on the symbol control board side, symbol variation display is not performed, and a stop symbol based on the stop symbol command is displayed at the final stop timing (“× )) Is displayed.
JP 2000-308745 A

  In the conventional ball and ball game machine described in Patent Document 1, when a command related to symbol variation is missed, the symbol variation may become very unnatural as a whole. For example, in a ball game machine in which the symbols stop in the order of left, right, and middle, the stop symbol in the previous symbol change is “3,7,5”, and the stop symbol in the current symbol change is 7, 5,7. If the stop symbol command related to the right symbol in this variation is missed, the game symbols on the left and right are not reach despite the symbol variation due to the reach variation pattern. The temporary stop is caused, and the variation pattern and the temporary stop symbol do not match, which is very unnatural.

  In addition, if the stop symbol in the previous symbol change is “3, 7, 5” and the stop symbol in the current symbol change is “7, 5, 7”, the stop symbol command for the middle symbol in the current change is missed. If it is, “7” in the previous change is used as the stop symbol for the middle symbol, and after a temporary stop in the big hit mode of “7 ・ 7 ・ 7”, the outage will be confirmed at “7 ・ × ・ 7”. As a result, the player's expectation is greatly betrayed, and the production effect is greatly negative.

  In view of such conventional problems, the present invention provides a ball game machine that does not impair interest by minimizing the unnaturalness of symbol variation even when a command related to symbol variation is missed. The purpose is to do.

In the present invention, a symbol display means 35 for variably displaying one or a plurality of game symbols, and a variation pattern and a stop symbol are selected from a plurality of types when starting the variability display of the game symbols by the symbol display means 35. And a main control board 41 that transmits at least a fluctuation pattern command that specifies the fluctuation pattern and a stop symbol command that specifies the stop pattern, and the fluctuation pattern command and the stop symbol that are transmitted from the main control board 41 side. In a ball game machine comprising a symbol control board 43 having a symbol control means 67 for controlling the variation display of the game symbols by the symbol display means 35 based on a command, a stop for error is provided on the symbol control board 43 side. an error for stop symbol storage means 65 for storing a pattern, corresponding to the error for stop symbol and the plurality of types of variation putter And error for change pattern storage unit 66b for storing a plurality of types of error for variation pattern substantially set to the same variable time as those of the time-varying in response to said stop symbols command transmitted from the main control board 41 side Stop symbol command error detecting means 64b for detecting a receiving error of the pattern pattern, and variation pattern command error detecting means 64a for detecting a reception error of the variation pattern command transmitted from the main control board 41 side. 67 corresponds to the variation pattern specified by the variation pattern designation command when a reception error is detected by the stop symbol command error detection unit 64b and no reception error is detected by the variation pattern command error detection unit 64a. The error variation pattern is the error variation pattern. Together selected from憶means 66b, so as to control and the error for change pattern, the variable display of the game symbols by said symbol display unit 35 on the basis of the error for the stop symbols stored in the error for stop symbol storage means 65 It is configured.

  According to the ball game machine of the present invention, even when a command related to symbol variation is missed, for example, when the symbol stops in the order of left, right, and middle, it is a symbol variation due to the reach variation pattern. There is no discrepancy between the variation pattern in which the game symbols on the left and right temporarily stop with a reachless symbol and the temporary stop symbol, and there is an advantage that the unnaturalness of the symbol variation can be minimized.

  Further, for example, if the stop symbol for error is a reachless stop symbol, a result that greatly disappoints the player's expectation that the game symbol temporarily stops in a big hit mode and is confirmed by the detach symbol will not occur.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1-10 has illustrated 1st Embodiment which employ | adopted this invention for the pachinko machine. In FIG. 1, reference numeral 1 denotes a gaming machine main body, which includes a rectangular outer frame 2 and a front frame 3 pivotally attached to the front side of the outer frame 2 so as to be openable and closable.

The upper plate cover 8 is formed with, for example, a slit-like sound output portion 8a for outputting the sound from the sound output means 9 such as a speaker to the front side.

  Reference numeral 10 denotes a lower pan for storing surplus spheres and the like, which is disposed on the lower side of the front plate 5 and on the front side of the front frame 3 and is covered with a lower pan cover 11. On one side of the lower plate 10, for example, on the right side, a firing handle 13 of the firing means 12 is provided in a protruding shape on the front side of the front frame 3.

  A game board 21 is detachably attached to the back side of the front frame 3 so as to correspond to the window hole 6 of the front frame 3. As shown in FIG. 2, the game board 21 is provided with a guide rail 22 for guiding a game ball fired from the launching means 12 in an annular shape, and is variable in a game area 23 inside the guide rail 22. Various game parts such as a display means 24, a normal symbol starting means 25, a special symbol starting means 26, a big winning means 27, a normal winning means 28 and the like are arranged.

  The variable display means 24 includes a display case 29 attached to the game board 21 from the front side, and a liquid crystal type variable display unit 30 disposed substantially at the center of the display case 29. The display case 29 is provided with normal symbol display means 31, normal reserved number display means 32, special reserved number display means 33, lamp means 34, and the like. The variable display unit 30 can display various moving images, still images, and the like, and constitutes a special symbol display means (symbol display means) 35.

  The normal symbol display means 31 is composed of, for example, a seven-segment display means capable of variably displaying one or a plurality of, for example, one normal symbol, and the normal symbol starting means 25 comprising a passing gate or the like is a game ball. If the normal symbol fluctuates for a predetermined time on condition that the normal symbol starting means 25 detects a game ball detected by the normal symbol starting means 25, the hit determination random number value coincides with a predetermined hit determination value. In an aspect, it is configured to stop in a disengagement mode otherwise.

  As a normal symbol, a numerical symbol, an alphabet symbol, a character symbol, and other symbols can be used as appropriate. In this embodiment, numerical symbols from “0” to “9” are used. In addition, a plurality of light emitters are provided as the normal symbol display means 31, and for example, a state in which the red light emitter emits light is set as a hit mode, and hit / miss is displayed according to the light emission state of the light emitter. Also good.

  Further, when the normal symbol starting means 25 detects a game ball during the fluctuation display of the normal symbol display means 31, the hit determination random number value acquired at the time of detection detects a predetermined upper limit reserved number, for example, four Is stored as a limit and, for example, the normal number-of-holds display means 32 comprising the same number of light-emitting means as the upper limit number of reserved numbers displays the number of stored random numbers for hit determination (hereinafter referred to as the number of normal holds) according to the number of light-emitting elements. The player is notified of the number of normally reserved items at that time.

  The special symbol starting means 26 is composed of a variable actuated electric tulip or the like having a pair of left and right open / close claws 26a that can be freely opened and closed. When a profit state occurs, the opening / closing claw 26a is operated in an open state for a predetermined time.

  The special symbol display means 35 is configured such that one or a plurality of, for example, three special symbols (game symbols) in the left-right direction can be variably displayed, and the special symbol starter 26 detects the game ball. The special symbols are variably displayed in accordance with a predetermined fluctuation pattern as a condition, and are stopped in a predetermined order such as left, right, and middle. The stop symbols after the change of the special symbol by the special symbol display means 35 are all, for example, when the jackpot determination random number value acquired at the time of detection of the game ball by the special symbol start means 26 matches a predetermined jackpot determination value. It becomes a big hit mode in which the special symbols are the same, and in other cases, at least one of the special symbols becomes a different mode in which the symbols are different.

  In addition, when the special symbol starting means 26 detects a game ball during the special symbol fluctuation display or the second profit state described later, the jackpot determination random number obtained at the time of the detection is a predetermined upper limit hold. The number (for example, four) is stored as a limit and, for example, the special reserved number display means 37 composed of the same number of light emitting means as the upper limit reserved number is used to store the number of random numbers for jackpot determination (hereinafter referred to as the special reserved number). And the player is notified of the number of special reserves at that time.

  As the special symbols, numeric symbols, alphabet symbols, character symbols, and other symbols can be used as appropriate. In this embodiment, ten types of symbols “0” to “9” are represented by the left symbol, the middle symbol, and the right symbol. We use each for design. In addition, there are special jackpot modes and normal jackpot modes in which all special symbols are the same. Special jackpot modes consisting of odd symbols such as “3, 3, 3” and “7, 7, 7” are special. A jackpot mode consisting of an even number of symbols such as “2, 2, 2”, “6, 6, 6”, etc., is normally designated as a jackpot mode.

  The special winning means 27 is a variable actuating type equipped with an opening / closing plate 27a that can be changed between an open state advantageous to the player and a closed state disadvantageous to the player, and the special symbol after the special symbol display means 35 changes. When the second profit state occurs based on the fact that the game is a big hit mode, the opening / closing plate 27a is opened to the front side for a predetermined time, and the game ball that has fallen thereon is awarded to the inside. . The large winning means 27 is divided into a plurality of passages such as three on the inner side, and a part of the passages is a specific area 38. The big winning means 27 closes the open / close plate 27a on the condition that a predetermined time (for example, 30 seconds) elapses from the opening or that a predetermined number (for example, ten) of gaming balls wins within the predetermined time, Is configured to repeat this opening / closing operation up to a predetermined predetermined round (for example, 16 rounds) on the condition that it passes through the specific region 38.

  FIG. 3 is a block diagram of the control system of the pachinko machine. In FIG. 3, 41 is a main control board, 42 is a sound lamp control board, 43 is a symbol control board, each of these control boards 41 to 43 is a variable display means 24 mounted on the game board 21, and a plurality of other The game parts are housed in board cases that are detachably mounted at appropriate positions on the back side of the gaming machine main body 1 including the front frame 3 and the game board 21 such as the back side of the back cover that collectively covers the gaming parts from the back side.

  The main control board 41 mainly performs control related to the game operation on the game board 21 side, and includes a first lottery means 51, a first profit state generating means 52, 2 lottery means 53, second profit state generation means 54, stop symbol selection means 55, variation pattern selection means 56, probability variation game state generation means 57, short-time game state generation means 58, control command transmission means 59, and the like.

  The first lottery means 51 is for drawing whether or not to make the stopped symbol after the fluctuation of the normal symbol display means 31 a hit state, that is, whether or not to generate the first profit state. For example, when the probability that the symbol is a hit state is 1/10, 10 hit determination random numbers from 0 to 9 are generated, and a predetermined number of hit determination random values according to the probability are repeatedly generated. Random number generation function, on the condition that the normal symbol starting means 25 detects a game ball, one random number value for determination is acquired, and a random number acquisition / storage that stores a predetermined upper limit holding number (for example, four) as a limit When the function and normal symbol display means 31 is in a state in which it can be variably displayed and one or more random numbers for hit determination are stored (that is, when the normal holding number is 1 or more), the hit determination stored earliest Random number for Ri out, determines whether or not to match the winning determination value that hit determination random number value is predetermined, and a win determination function for outputting a determination result of the mode Upon If they match.

  The first profit state generating means 52 generates a first profit state that opens the special symbol starting means 26. When the determination result by the first lottery means 51 is a hit mode determination, the normal profit display means 31 changes. The opening / closing claw 26a of the special symbol starting means 26 is configured to be opened for a predetermined time on the basis that the subsequent normal symbol is in a hit state.

  The second lottery means 53 is for drawing whether or not the stop symbol after the change of the special symbol is a big hit mode, that is, whether or not the second profit state is generated. The special symbol after the change is a big hit Random number generation function that repeatedly generates a random number for jackpot symbol used for selection of stop symbol when a special symbol after change is a jackpot mode, and other predetermined random number The special symbol starting means 26 detects a game ball and obtains a jackpot determination random number value and a jackpot symbol random number value, respectively, and holds each predetermined random number value in association with each other. For example, a random number acquisition / storage function that stores the number (for example, 4 each) in the order of acquisition, the special symbol display means 35 can be variably displayed, and one or more jackpot determination random numbers are recorded. When the number is set (when the number of special hold is 1 or more), the jackpot determination random number value that is stored first is taken out, and the jackpot determination random number value matches the predetermined jackpot determination value A jackpot determination function for outputting the determination result of (second profit state occurrence) is provided.

  The second profit state generating means 54 is configured such that when the jackpot determination result by the second lottery means 53 is a jackpot mode determination, the special symbol after the change of the special symbol display means 35 is a jackpot mode such as “7/7/7” This is to generate a second profit state that is advantageous to the player based on the above.

  The second profit state generating means 54 opens the opening / closing plate 27a of the big winning means 27 after the special symbol after the change of the special symbol display means 35 becomes a big hit mode, and also after the opening / closing plate 27a is opened for a predetermined time ( For example, when 30 seconds) elapses or a predetermined number (for example, 10 seconds) of game balls has been won in the big winning means 27 before the elapse of a predetermined time (for example, 30 seconds), the open / close plate 27a is closed and the game is further won The opening / closing operation is continued up to a predetermined predetermined round (for example, 16 rounds) on condition that the sphere passes through the specific region 38.

  The stop symbol selection means 55 is for selecting a stop symbol of the special symbol after the change. When the determination result by the second lottery means 53 is a big hit mode determination, the big hit that is acquired and stored together with the random number for jackpot determination Based on the design random number value, one of 10 types of jackpot modes from “0, 0, 0” to “9, 9, 9” is selected, and the determination result by the second lottery means 53 is determined to be out of mode. In this case, for example, three newly acquired random numbers for left, right, and middle are obtained one by one, and one of the outliers is selected based on these three random numbers for out symbol It is supposed to be.

  At the time of detachment mode determination, the stop symbol selection means 55 determines, for example, the left symbol based on the random symbol value for the left-off symbol, and the difference value between the left symbol and the right symbol based on the random symbol value for the right-off symbol, A difference value between the left symbol and the middle symbol is determined based on the random number value for the off symbol. Therefore, when the difference value selected based on the random symbol value for off-right symbol is 0, the fluctuation is accompanied by a reach state. In this case, the left symbol and the middle symbol selected based on the random value for off-center symbol are selected. Is always a value other than 0. Of course, it is determined whether or not to reach using a random number for reach determination different from the random number for out-of-design, and a stop pattern of out-of-phase is selected based on the result and a plurality of random numbers for out-of-design You may make it do.

  The variation pattern selection unit 56 selects one of a plurality of types of variation patterns by random lottery or the like based on at least one of the determination result by the second lottery unit 53 and the selection result of the stop symbol selection unit 55. Is.

  In the present embodiment, as shown in FIG. 4, four types of reach jackpot variation patterns A to D, four types of reach outbreak variation patterns E to H corresponding to them, and one type of reach outbreak variation pattern I Are selectable, and each is set to a predetermined fluctuation time. Hereinafter, the variation patterns A to I that can be selected by the variation pattern selection means 56 are referred to as normal variation patterns.

  For example, if the determination result by the second lottery means 53 is a detachment mode determination and the selection result of the stop symbol selection means 55 is a detachment symbol other than reach, the variation pattern selection unit 56 determines the detachment variation pattern I without reach, When the determination result of the second lottery means 53 is the detachment state determination and the selection result of the stop symbol selecting means 55 is the reach out of symbol, the reach out of variation pattern E˜ is based on the newly acquired random number for variation pattern. If the determination result of the second lottery means 53 is a jackpot mode determination, any one of H is selected from the reach jackpot variation patterns A to D based on the random number value for the variation pattern.

  The probability variation gaming state generation means 57 is for generating a probability variation gaming state that is advantageous to the player after the end of the second profit state (or after the occurrence). For example, the stop symbol selection means 55 has a special jackpot mode. After the second profit state ends, for example, the special symbol becomes a normal jackpot mode out of the jackpot mode, and the next second profit state is generated on condition that the special symbol after the change is selected and the special jackpot mode is selected Probability game state is generated until it is done.

  During the probable gaming state, the probability that the special symbol will be a big hit mode changes from the normal probability (for example, 1/300 low probability) to the high probability (for example, about 1/60), for example, the normal symbol display means 31 and the special symbol display The variation time of the means 35 becomes a shortened variation time shorter than the normal variation time, and the opening time and / or the number of times of opening the special symbol starting means 26 are increased more than usual.

  The short-time gaming state generation means 58 is for generating a short-time gaming state that is advantageous to the player after the end of the second profit state (or after the occurrence). A short-time gaming state is generated for a predetermined period after the end of the second profit state, for example, until the special symbol fluctuates a predetermined number of times (for example, 100 times), provided that the special symbol after the change becomes a normal jackpot mode. It is supposed to let you.

  During the short-time gaming state, the variation time of the special symbol display means 35 becomes a shortened variation time shorter than the normal variation time. For example, the variation time of the normal symbol display means 31 becomes a shortened variation time shorter than the normal variation time. The opening time and / or the number of opening times of the symbol starting means 26 are increased more than usual.

  The control command transmission means 59 is for transmitting a predetermined control command to the sub-control board side such as the sound lamp control board 42 and the design control board 43 by one-way communication and giving a control command. Based on the detection of the game ball, the function of transmitting a normal symbol variation control command to the symbol control board 43 side via the voice lamp control board 42 based on the determination result of the first lottery means 51, special symbol start Based on the detection result of the second lottery means 53, the stop symbol selected by the stop symbol selection means 55, the fluctuation pattern selected by the fluctuation pattern selection means 56, etc. A special pattern variation control command such as a variation pattern command, a stop symbol command, or a variation stop command is sent to the symbol control board 43 side via the voice lamp control board 42. Function of transmitting, and a function of transmitting speech, the control commands of the lamp to the voice lamp control board 42 side in accordance with various gaming state.

  Here, when the control command transmission means 59 transmits a special symbol variation control command to the symbol control board 43 side, first, a variation pattern command, a left stop symbol command, a right stop symbol command, and a middle stop symbol command are predetermined. It is configured to transmit sequentially every time (for example, every 4 msec), and transmit a stop symbol command when a variation time corresponding to the variation pattern has elapsed after transmission of the variation pattern command.

  The sound lamp control board 42 is for controlling the sound output means 9, the lamp means 34, and the like, and includes a sound control means 61, a lamp control means 62, and the like constituted by a CPU, a ROM, a RAM, and the like.

  The sound control means 61 performs sound output control of the sound output means 9 such as a speaker, and outputs a predetermined sound effect or the like from the sound output means 9 based on a sound control command from the main control board 41 side. It has become.

  The lamp control unit 62 performs display control of the lamp unit 34 and the like, and causes the lamp unit 34 and the like to emit light in a predetermined pattern based on a lamp control command from the main control board 41 side.

  The symbol control board 43 is for controlling the normal symbol display means 31, the special symbol display means 35, etc., and the normal symbol control means 63, command error detection means 64, error, etc., constituted by a CPU, ROM, RAM, etc. A stop symbol storage unit 65, a fluctuation pattern storage unit 66, a special symbol control unit 67, and the like are provided.

  The normal symbol control means 63 controls the display of the normal symbol display means 31, and changes the normal symbol of the normal symbol display means 31 for a predetermined time based on a normal symbol variation control command from the main control board 41 side. The normal symbol is stopped in a hit mode such as “7” when the determination result by the first lottery means 51 is a hit mode determination, and in the off mode in other cases.

  The command error detecting means 64 detects a reception error of a control command transmitted from the main control board 41 side, that is, when a control command that should have been transmitted from the main control board 41 side cannot be normally received. Is detected as a reception error, and includes a variation pattern command error detection means 64a, a stop symbol command error detection means 64b, and the like.

  The fluctuation pattern command error detection means 64a detects a reception error of the fluctuation pattern command transmitted from the main control board 41 side. For example, the fluctuation pattern command error detection means 64a is transmitted after the fluctuation pattern command without receiving the fluctuation pattern command. When a command, for example, a stop symbol command is received, a detection signal of a fluctuation pattern reception error is output.

  The stop symbol command error detecting means 64b detects a stop symbol command reception error transmitted from the main control board 41 side, and the stop symbol command that should have been continuously transmitted despite receiving the variation pattern command. Is not received at a predetermined timing, another stop symbol command (such as a right stop symbol command) is received without receiving a variation pattern command and a stop symbol command (such as a left stop symbol command) that should have been transmitted first. If a variable stop command is received without receiving a variable pattern command and all stop symbol commands, the stop symbol command reception error detection signal corresponding to the stop symbol command that could not be received is output. Has been.

  The error stop symbol storage means 65 stores an error stop symbol used when a reception error occurs for at least one stop symbol command. As the error stop symbols, a predetermined type, for example, one type of stop symbols other than the reach stop symbols is set. It is assumed that “7, 3, 6” is stored as the error stop symbol in the error stop symbol storage means 65 of the present embodiment.

  The variation pattern storage unit 66 stores variation display data of each variation pattern related to the special symbol, and includes a normal variation pattern storage unit 66a and an error variation pattern storage unit 66b.

  The normal variation pattern storage unit 66a is a variation pattern used when a variation control command for a special symbol is normally received without an error, that is, a normal target that is a selection target of the variation pattern selection unit 56 on the main control board 41 side. For example, variation display data for nine types of normal variation patterns A to I shown in FIG. 4 is stored in advance.

  The error variation pattern storage unit 66b stores variation display data of an error variation pattern used when at least one of a variation pattern command and a stop symbol command results in a reception error. For example, as shown in FIG. Fluctuation display data for nine types of error variation patterns a to i are stored in advance. Here, the error variation patterns a to i are all reachless variation patterns corresponding to the error stop symbols stored in the error stop symbol storage means 65. As shown in FIGS. 4 and 5, the nine types of error variation patterns a to i are set to the same variation time as the normal variation patterns A to I, respectively. The variation times of the error variation patterns a to i are preferably substantially the same as the variation times of the normal variation patterns A to I, but may be at least shorter than the variation times of the normal variation patterns A to I, respectively.

  The special symbol control means 67 controls the display of the special symbol display means 35. In the normal case where there is no reception error for the special symbol fluctuation control command, the special symbol control means 67 receives the fluctuation pattern command from the main control board 41 side. Sometimes, the fluctuation display data of the normal fluctuation pattern corresponding to the fluctuation pattern command is read from the normal fluctuation pattern storage means 66a and the special symbol display means 35 starts to display the fluctuation display of the special symbols according to the fluctuation pattern. For example, after temporarily stopping at the stop symbol specified by the stop symbol command, when the variable stop command is received, the change of the special symbol is stopped / confirmed by the stop symbol specified by the stop symbol command. .

  Also, the special symbol control means 67 performs symbol variation control processing as shown in FIGS. 6 and 7 when the command error detection means 64 detects a reception error for either the variation pattern command or the stop symbol command. Configured to do.

  That is, as shown in case 1 of FIG. 6, when a variation pattern command reception error is detected by the variation pattern command error detection means 64a, and a stop symbol command reception error is not detected by the stop symbol command error detection means 64b. In response to the stop symbol command that has been successfully received, the special symbol control means 67 has the longest variation time among the normal variation patterns corresponding to the type of stop symbol (reach big hit, out of reach, out of reach). The special symbol display means 35 starts the variation display of the special symbol according to the error variation pattern set at the same variation time as the short normal variation pattern, and each special symbol is stored in the error stop symbol storage means 65. After temporarily stopping with the stop symbol for use, when a variable stop command is received, And it is adapted to stop and determine the variation of the special symbols in the specified stop symbol in degrees.

  For example, as shown in FIG. 8, the variation pattern command corresponding to the normal reach 1 deviation variation pattern G from the main control board 41 side, the left stop symbol command corresponding to the stop symbol “7”, and the right corresponding to the stop symbol “7”. The stop symbol command and the middle stop symbol command corresponding to the stop symbol “5” are sequentially transmitted, and the variation stop command is transmitted after 35 seconds corresponding to the variation time of the variation pattern G out of the normal reach 1 from the variation pattern command transmission, If the fluctuation pattern command cannot be normally received on the symbol control board 43 side, the fluctuation pattern command error detection means 64a changes when the left stop symbol command is received on the symbol control board 43 side (t1). A pattern command reception error is detected.

  When a reception error of the variation pattern command is detected, when all stop symbol commands are received (t2), the type of stop symbol “7, 5 and 7” that can be specified from these stop symbol commands, that is, “reach out” Of the special symbol by the special symbol display means 35 according to the error variation pattern h set to the same variation time (25 seconds) as the normal variation 2 out-of-variation variation pattern H with the shortest variation time. By the time the fluctuation display is started and 25 seconds, which is the fluctuation time of the error fluctuation pattern h, has elapsed, each special symbol is temporarily stopped at the error stop pattern “7.3.6” and a fluctuation fluctuation state is obtained. When the change stop command is received, each symbol that has been shaken and changed by “7, 3 and 6” until then is stopped and confirmed by the stop symbol “7, 5 and 7” specified by the stop symbol command. Is done.

  In Case 1, for example, when the fluctuation stop command cannot be received normally, the fluctuation fluctuation state (temporary stop state) is continued until the next fluctuation pattern command or the like is received.

  As described above, in the case 1 in which a variation pattern command reception error is detected by the variation pattern command error detection means 64a and a stop symbol command reception error is not detected by the stop symbol command error detection means 64b, the error for reach is not detected. After making a change using the change pattern and temporarily stopping with the stop symbol for error without reach, stop and confirm with the stop symbol specified by the stop symbol command that was received normally, so at least the symbols until just before confirmation Regarding fluctuations, for example, despite the fact that it is a symbol variation due to a reach variation pattern, there is no unnatural symbol variation such that the game symbol on the left and right temporarily stops with a non-reach symbol, and the temporary stop symbol is confirmed. In some cases, there will be a shift in the design, but after the temporary stop in the big hit mode, it will be confirmed with the release symbol. Large betray such a result the expectations of the player's Runado does not occur.

  In addition, the variation time of the error variation pattern used is the same as the shortest variation time among the normal variation patterns corresponding to the type of the stop symbol specified based on the stop symbol command that has been successfully received. In the middle of symbol variation, the symbol does not stop or be fixed suddenly, and the temporary stop state (fluctuation variation state) can be shortened as much as possible, and the variation in symbol variation when a command reception error occurs There is an advantage that can be made as small as possible.

  Further, as shown in cases 2 to 7 in FIG. 6, when not only the variation pattern command reception error but also the stop symbol command error detection means 64b detects the stop symbol command reception error, the special symbol control means 67 starts the special symbol variation display according to the error variation pattern i having the shortest variation time among the error variation patterns a to i, and each special symbol is stored in the error stop symbol storage means 65 for error. When a variable stop command is received after a temporary stop with a stop symbol, a special error corresponding to the stop symbol command that was successfully received resulted in a reception error with the stop symbol specified by the stop symbol command With regard to the special symbol corresponding to the stop symbol command, a predetermined error symbol, for example, “×”, stops the variation of the special symbol. To have.

  For example, as shown in FIG. 9, from the main control board 41 side, the variation pattern command corresponding to the normal reach 1 deviation variation pattern G, the left stop symbol command corresponding to the stop symbol “7”, and the right corresponding to the stop symbol “7” The stop symbol command and the middle stop symbol command corresponding to the stop symbol “5” are sequentially transmitted, and the variation stop command is transmitted after 35 seconds corresponding to the variation time of the variation pattern G out of the normal reach 1 from the variation pattern command transmission, When the variation pattern command and the right stop symbol command cannot be normally received on the symbol control board 43 side, the variation pattern command is received when the left stop symbol command is received on the symbol control board 43 side (t11). The error detection means 64a detects a variation pattern command reception error, and stops to the left on the symbol control board 43 side. When following the pattern command right stop symbols command has not been received (t12), the reception error of the right stop symbols command is detected by the stop symbol command error detection unit 64b.

  When the reception error of the variation pattern command is detected, when the reception timing of all stop symbol commands has elapsed (here, when the middle stop symbol command is received), the variation time of the error variation patterns a to i is the longest. In accordance with the short error variation pattern i, special symbol display by the special symbol display means 35 is started (t13), and each special symbol is used for error until 15 seconds, which is the variation time of the error variation pattern i, elapses. Temporarily stops at the stop symbol “7, 3, 6”, and the state of fluctuation changes. And when the change stop command is received, each symbol that has been shaken and changed by “7, 3 and 6” until then is the special symbol on the left and inside corresponding to the stop symbol command that could be received normally. Stop symbols “7” and “5” designated by these stop symbol commands, and a special symbol corresponding to the right stop symbol command resulting in a reception error are “x” and the stop symbol “7 · 5 · ×”. To stop and confirm (t14).

  In cases 2 to 7 in FIG. 6, that is, when not only a variation pattern command reception error but also a stop symbol command reception error is detected by the stop symbol command error detection means 64b, the reception is successful. If the type of stop symbol can be limited as much as possible based on the specified stop symbol command, an error with the same variation time as the one with the shortest variation time among the normal variation patterns corresponding to the limited stop symbol type The design variation may be performed using the business variation pattern. For example, if only the left and right stop symbol commands can be received normally, and the stop symbol specified by those commands is the same, the type of the stop symbol is “reach big hit” or “reach miss” Since it can be limited, symbol variation is performed using the error variation pattern h corresponding to the normal reach 2 variation pattern H having the shortest variation time among the reach jackpot variation patterns A to D and the reach deviation variation patterns E to H. What should I do?

  Also, as shown in case 8 of FIG. 6, when all of the variation pattern command and the stop symbol command result in a reception error, for example, when the variation stop command is received, all the special symbols are set to a predetermined error symbol, For example, “x” may be displayed. If the fluctuation stop command cannot be received, the symbol control board 43 cannot recognize that the special symbol has changed, so that the special symbol fluctuation display is not performed.

  As described above, not only the variation pattern command reception error, but also the stop symbol command reception error is detected by the stop symbol command error detection means 64b (except when all stop symbol commands result in reception errors). Also in the case of ˜7, the fluctuation pattern is used using the fluctuation pattern for error without reach, temporarily stopped with the stop pattern for error without reach, and then the stop pattern specified by the stop pattern command that has been successfully received ( If a reception error occurs, it is stopped and confirmed with “×”). Therefore, at least for the symbol variation until just before the decision, for example, the symbols on the left and right are not reach despite the symbol variation due to the reach variation pattern. There is no unnatural pattern change that causes a temporary stop. Although occurs, never greater betray such results expected by the player, such as determining at symbol out after the temporary stop at jackpot manner occurs.

  In addition, as shown in cases 11 to 17 in FIG. 7, when a variation pattern command reception error is not detected and a stop symbol command reception error is detected by the stop symbol command error detection means 64b, first, normally The fluctuation display data of the normal fluctuation pattern corresponding to the received fluctuation pattern command is read from the normal fluctuation pattern storage means 66a, and the special symbol fluctuation display by the special symbol display means 35 is started according to the fluctuation pattern, and then the stop symbol command When a reception error is detected, or at a predetermined timing thereafter, the fluctuation display data of the normal fluctuation pattern used at that time is changed to the error fluctuation pattern set for the same fluctuation time as the normal fluctuation pattern. Switch to fluctuation display data and continue symbol fluctuation control to save each special symbol. -For the special symbol corresponding to the stop symbol command that can be normally received when the variable stop command is received after temporarily stopping with the error stop symbol stored in the stop symbol storage means 65, the stop symbol With respect to a special symbol corresponding to a stop symbol command that has caused a reception error in the stop symbol designated by the command, the variation of the special symbol is stopped / confirmed with a predetermined error symbol, for example, “×”.

  For example, as shown in FIG. 10, from the main control board 41 side, it corresponds to the variation pattern command corresponding to the super reach one big hit variation pattern A, the left stop symbol command corresponding to the stop symbol “7”, and the stop symbol “7”. The right stop symbol command and the middle stop symbol command corresponding to the stop symbol “7” are sequentially transmitted, and the variable stop command is transmitted after 55 seconds corresponding to the variation time of the super reach one big variation pattern A from the variation pattern command transmission. If the left stop symbol command cannot be normally received on the symbol control board 43 side, when the variation pattern command is received on the symbol control board 43 side (t21), it corresponds to the variation pattern command. According to Super Reach 1 jackpot variation pattern A, the special symbol display by the special symbol display means 35 is opened. It is.

  After that, when the stop symbol command error detecting means 64b detects a left stop symbol command reception error because the symbol control board 43 side does not receive the left stop symbol command following the variation pattern command (t22), at that time The change display data of the super reach 1 big hit fluctuation pattern A used in the above is switched to the fluctuation display data of the error fluctuation pattern a set to the same fluctuation time (55 seconds) as the super reach 1 big hit fluctuation pattern A The pattern variation control is continued according to the error variation pattern a.

  Then, until 55 seconds, which is the fluctuation time of the error fluctuation pattern a, elapses, each special symbol temporarily stops at the error stop pattern “7, 3, 6”, becomes a fluctuation fluctuation state, and a fluctuation stop command is received. The symbols that had been fluctuated by "7, 3, 6" until then were designated by the stop symbol command for the special symbols in the right and middle corresponding to the stop symbol command that was successfully received. The special symbol corresponding to the left stop symbol command resulting in the stop symbol “7” “7” is stopped / confirmed with the stop symbol “× · 7 · 7” as the error symbol “×” (t14). ).

  In these cases 11 to 17, the fluctuation display data is switched to the error fluctuation pattern in the middle of the symbol fluctuation display by the normal fluctuation pattern, but the switching timing is after a lapse of a minute time from the start of the fluctuation by the normal fluctuation pattern. Since it is (for example, after 4 msec), the variation due to the normal variation pattern cannot be recognized first by the naked eye, and the display does not feel unnatural.

  As described above, even in the case of the cases 11 to 17 in which the reception error of the stop symbol command is not detected by the stop symbol command error detecting unit 64b and the stop symbol command reception error is detected, the error fluctuation pattern without reach , And temporarily stop with the stop symbol for error without reach, then stop with the stop symbol specified by the stop symbol command that was successfully received (“×” for the reception error) In order to confirm, at least the symbol variation until just before the decision is made, for example, an unnatural symbol variation such that the game symbol on the left and right temporarily stops at a symbol that is not reach despite the symbol variation due to the reach variation pattern. Although there is a shift in the design when the temporary stop symbol is confirmed, the symbol is released after the temporary stop in a big hit mode There is no possibility that large betray such a result the expectations of the player, such as to confirm results.

  Also, because the fluctuation time of the error fluctuation pattern used is the same as the fluctuation time of the normal fluctuation pattern specified by the normally received fluctuation pattern command, the temporary stop state (swing fluctuation state) continues for a long time. There is an advantage that the unnaturalness of the pattern fluctuation when the command reception error occurs is minimized.

  As described above, in the present embodiment, the error control symbol storage means 65 for storing the error stop symbol on the symbol control board 43 side and the reception error of the stop symbol command transmitted from the main control board 41 side are displayed. Stop symbol command error detecting means 64b for detecting, and the special symbol control means 67, when a reception error is detected by the stop symbol command error detecting means 64b, the error stored in the error stop symbol storage means 65 Since the special symbol display means 35 controls the variation display of the special symbol on the basis of the stop symbol for error and the error variation pattern (predetermined variation pattern) corresponding to the stop symbol for error. Even if a command related to fluctuation is missed, for example, it is left and right despite the pattern fluctuation due to the reach fluctuation pattern. Game symbols not a mismatch between the variation pattern and the temporary stop symbol such that the temporary stop occurs without reach pattern, it is possible to minimize the unnaturalness of symbol variation.

  In addition, since the stop symbol for error is a stop symbol without reach, there is no result that greatly disappoints the player's expectation such as temporarily stopping in a big hit mode and confirming with a symbol that is out.

  Further, on the symbol control board 43 side, a plurality of types of error variation patterns a corresponding to the error stop symbols and set to the same variation time corresponding to the plurality of types of normal variation patterns A to I. ˜i are stored, and a variation pattern command error detection unit 64a for detecting a reception error of the variation pattern command transmitted from the main control board 41 side is provided. The special symbol control unit 67 includes: When a reception error is detected by the stop symbol command error detection means 64b and no reception error is detected by the fluctuation pattern command error detection means 64a, an error fluctuation pattern corresponding to the fluctuation pattern designated by the fluctuation pattern designation command is given an error. The variation pattern storage means 66b selects the error variation Since the special symbol display means 35 controls the change display of the special symbol based on the turn and the error stop symbol stored in the error stop symbol storage means 65, for example, a temporary stop state (swaying) (Variation state) is not continued for a long time, and there is an advantage that the unnaturalness of the pattern fluctuation when a command reception error occurs can be minimized.

  When the special symbol control means 67 receives the fluctuation pattern command, the special symbol control means 67 starts the fluctuation display of the special symbol according to the normal fluctuation pattern specified by the fluctuation pattern command, and the stop symbol command error detection means 64b detects the reception error. Therefore, it is configured to switch the fluctuation display data of the normal fluctuation pattern during the fluctuation display to the fluctuation display data of the error fluctuation pattern and continue to display the fluctuation display of the special symbol. The symbol variation can be performed by the error variation pattern in response to the stop symbol command reception error in spite of being configured to start the symbol variation.

  Also, the special symbol control means 67, when both the variation pattern command error detection means 64a and the stop symbol command error detection means 64b detect a reception error, the error symbol stored in the error variation pattern storage means 66b. Since the pattern having the shortest variation time is selected from among the variation patterns, even if the variation pattern command is missed and the variation pattern selected on the main control board 41 side cannot be recognized, the symbol variation display of the special symbol is displayed. Can be done without problems.

  The main control board 41 is configured to transmit a fluctuation stop command for instructing the special symbol display means 35 to stop changing the special symbol, and the special symbol control means 67 receives the fluctuation stop command from the main control board 41 side. The special symbol corresponding to the stop symbol command that is normally received is the stop symbol specified by the stop symbol command, and the special symbol corresponding to the stop symbol command resulting in the reception error is predetermined. Since each error symbol, for example, “x” is configured to stop display, it is possible to prevent a mismatch between the result of symbol variation and the gaming state.

  Also, the error variation pattern storage means 66b for storing a plurality of types of error variation patterns a to i having different variation times according to the type of stop symbol is transmitted to the symbol control board 43 side, and the main control board 41 side. Fluctuation pattern command error detection means 64a for detecting a reception error of the fluctuation pattern command. The special symbol control means 67 is a stop symbol command when a reception error is detected by the fluctuation pattern command error detection means 64a. The error variation pattern corresponding to the designated stop symbol type is selected from the error variation pattern storage means 66b, and the special symbol display is performed based on the error variation pattern and the stop symbol designated by the stop symbol command. Since it is configured to control the display of variation of the game symbol by means 35, the variation pattern Even if the variation pattern selected on the main control board 41 side cannot be recognized by missing the command, the symbol variation display of the special symbol can be performed without any problem and, for example, the left and right are changed regardless of the symbol variation due to the reach variation pattern. There is no discrepancy between the variation pattern and the temporary stop symbol such that the game symbol of the game is temporarily stopped with the non-reach symbol, and the unnaturalness of the symbol variation can be minimized.

  The symbol control board 43 is provided with a stop symbol command error detecting means 64b for detecting a reception error of the stop symbol command transmitted from the main control board 41, and the special symbol control means 67 is provided by the stop symbol command error detecting means 64b. When a reception error is detected, the variation pattern command is configured to select the one with the shortest variation time among the error variation patterns a to i stored in the error variation pattern storage means 66b. Not only can the stop symbol command be missed, it is possible to perform symbol variation with minimal unnaturalness.

  In this case, instead of selecting the error variation patterns a to i having the shortest variation time, the type of the stop symbol is limited based on the normally received stop symbol command and the limited stop symbol is selected. If it is configured to select the error variation pattern corresponding to the type of error with the shortest variation time, the duration of the temporary stop state can be shortened as much as possible, further eliminating the unnaturalness of symbol variation. it can.

  FIG. 11 and FIG. 12 illustrate the second embodiment of the present invention, and the timing of the start of fluctuation of the special symbol is changed, and the fluctuation pattern command and the stop symbol command are normally received or a reception error is detected. In this example, the special symbol control means 67 is configured to start the variation of the special symbol.

  That is, the special symbol control means 67 transmits the latest one of the variation pattern command and each stop symbol command from the main control board 41 side regardless of whether a reception error such as a variation pattern command is detected. The command, that is, the middle stop symbol command is normally received or a special symbol is changed after a reception error is detected, and the main control board 41 side correspondingly transmits the middle stop symbol command. The change stop command is transmitted when the change time of the normal change pattern selected by the change pattern selection means 56 has elapsed.

  With this configuration, in the cases 11 to 17 shown in FIG. 11, that is, when a reception error of the stop symbol command is detected after the variation pattern command is normally received, it is designated by the variation pattern command. Instead of starting the symbol variation once with the normal variation pattern and then switching to the error variation pattern, the symbol variation can be started with the error variation pattern from the beginning.

  For example, as shown in FIG. 12, from the main control board 41 side, it corresponds to the variation pattern command corresponding to the super reach one big hit variation pattern A, the left stop symbol command corresponding to the stop symbol “7”, and the stop symbol “7”. The right stop symbol command and the middle stop symbol command corresponding to the stop symbol “7” are sequentially transmitted, and the variable stop command is issued after 55 seconds corresponding to the variation time of the super reach one big variation pattern A from the transmission of the middle stop symbol command. When the left stop symbol command is not normally received on the symbol control board 43 side, the fluctuation received normally when the middle stop symbol command is received on the symbol control board 43 side (t31). Fluctuation pattern for error that is set to the same fluctuation time as the fluctuation pattern A of super reach one big hit specified by the pattern command Fluctuations in the special symbol display is started in accordance with a.

  Then, until 55 seconds, which is the fluctuation time of the error fluctuation pattern a, elapses, each special symbol temporarily stops at the error stop pattern “7, 3, 6”, becomes a fluctuation fluctuation state, and a fluctuation stop command is received. The symbols that had been fluctuated by "7, 3, 6" until then were designated by the stop symbol command for the special symbols in the right and middle corresponding to the stop symbol command that was successfully received. Stop symbols “7” and “7”, and the special symbol corresponding to the left stop symbol command resulting in a reception error is stopped / confirmed with the stop symbol “× · 7 · 7” with the error symbol “×” (t32 ).

  As described above, after the fluctuation pattern command and the stop symbol command are normally received or a reception error is detected, that is, among the variation pattern command and the stop symbol command, the latest transmission from the main control board 41 side. If the command (for example, the medium stop symbol command) is normally received on the symbol control board 43 side or a reception error is detected, the special symbol control means 67 starts the variation of the special symbol. Regardless of whether or not a reception error such as a fluctuation pattern command is detected, the timing of the start of fluctuation of the special symbol can be made constant and the stop symbol command When a reception error is detected, symbol variation can be started from the beginning with an error variation pattern.

  As mentioned above, although each embodiment of this invention was explained in full detail, this invention is not limited to these each embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, the error variation patterns stored in the error variation pattern storage unit 66b do not have to be provided in a one-to-one correspondence with the normal variation patterns A to I, but 1 for a plurality of normal variation patterns. Two error variation patterns may be provided. In this case, it is necessary to set the variation time of the error variation pattern to be equal to or shorter than the shortest variation time among the plurality of normal variation patterns corresponding thereto.

  The reach pattern may be included in the error stop symbol, and the reach variation pattern may be included in the error variation pattern accordingly. In this case, for example, when it is recognized that the reach mode is achieved based on a normally received variation pattern command or stop symbol command, the error variation pattern and the error stop symbol may be used.

  Two or more types of error stop symbols stored in the error stop symbol storage means 65 may be provided.

  When the fluctuation pattern command is received normally and the stop symbol command results in a reception error (cases 11 to 17), the special symbol is variably displayed according to the normal fluctuation pattern specified by the fluctuation pattern command, and the normal fluctuation is displayed. You may comprise so that it may stop temporarily with the stop pattern for errors corresponding to a pattern. In this case, it is necessary to provide at least one error stop symbol for at least all types (no reach, miss reach, big hit of reach). Further, in this case, it is desirable that the error stop symbol corresponding to the reach jackpot is normally set to the jackpot mode.

  The error symbol used as a confirmed symbol when a stop symbol command results in a reception error is not limited to “x”, and any symbol such as a character symbol can be used, but the error symbol is a stop symbol. It should be used only when a command results in a reception error.

  Informing means for notifying that a symbol variation related to a reception error may be provided when a special symbol variation is displayed when a variation pattern command or stop symbol command reception error is detected. This notifying means performs a predetermined display such as “communication error” on the screen of the special symbol display means 35, outputs a sound different from the normal time, and displays the lamp means 34 in a pattern different from the normal time. Anything, such as what makes it light-emit, may be sufficient.
