<Type of design>
Next, using FIGS. 5A to 5C, the first special symbol display device 212, the second special symbol display device 214, the decorative symbol display device 208, and the normal symbol display device 210 of the pachinko machine 100 are stopped and displayed. The types of special maps and general maps to be described will be described.

  Fig.5 (a) shows an example of the stop symbol aspect of a special figure.

  The special figure 1 variable game is started on the condition that the first start port sensor detects that the ball has entered the first special figure start port 230, and the ball has entered the second special figure start port 232 The special figure 2 variable game is started on the condition that the second start port sensor has detected.

  When the special figure 1 variable game is started, the first special symbol display device 212 performs “variable display of special figure 1” by repeating all lighting of seven segments and lighting of one central segment. In addition, when the special figure 2 variable game is started, the second special symbol display device 214 displays “fluctuation display of special figure 2” which repeats lighting of all seven segments and lighting of one central segment. Do. These “variation display of special figure 1” and “variation display of special figure 2” correspond to an example of the symbol fluctuation display according to the present invention.

  Then, when the variation time determined before the variation start of the special figure 1 (corresponding to the variation time referred to in the present invention) elapses, the first special symbol display device 212 stops and displays the special symbol form of the special figure 1. When the variation time determined before the start of variation 2 (this also corresponds to the variation time according to the present invention) has elapsed, the second special symbol display device 214 stops and displays the stop symbol form of the special diagram 2.

  Therefore, from the start of “figure display of special figure 1” until the stop symbol form of special figure 1 is stopped, or after the start of “fluctuation display of special figure 2”, the stop symbol form of special figure 2 is displayed. Until stop display corresponds to an example of the symbol variation stop display referred to in the present invention, hereinafter, after the “variable display of special figure 1 or 2” is started, the stop symbol form of special figure 1 or 2 is stopped and displayed. The series of displays up to is referred to as symbol variation stop display. As will be described later, the symbol variation stop display may be continuously performed a plurality of times.

  FIG. 5A shows ten types of special drawings from “Special Figure A” to “Special Figure J” as the stop symbol forms in the symbol variation stop display. In FIG. 5 (a), the white portions in the drawing indicate the locations of the segments that are turned off, and the black portions indicate the locations of the segments that are turned on.

  “Special Figure A” is a 15 round (15R) special jackpot symbol, and “Special Figure B” is a 15R jackpot symbol. In the pachinko machine 100 according to the present embodiment, as will be described later, the determination as to whether or not the big hit in the special figure variable game is made by lottery of hardware random numbers, and the decision as to whether or not it is a special big hit is made by lottery of software random numbers. The difference between the jackpot and the special jackpot is whether the probability of winning the jackpot is high (special jackpot) or low (jackpot) in the next special figure variation game. Hereinafter, a state having a high probability of winning the jackpot is referred to as a special figure high probability state, and a state having a low probability is referred to as a special figure low probability state. Moreover, after the 15R special jackpot game ends and after the 15R jackpot game ends, both shift to the time-saving state. Although the time reduction will be described in detail later, the state that shifts to the time reduction state is referred to as a normal high probability state, and the state that does not shift to the time reduction state is referred to as a normal low probability state. “Special figure A”, which is a 15R special jackpot symbol, is a special figure high probability normal figure high probability state, and “Special figure B”, which is a 15R jackpot symbol, is a special figure low probability ordinary figure high probability state. These “special chart A” and “special chart B” are symbols that give a relatively large profit amount to the player.

  “Special figure C” is a 2R jackpot symbol called sudden probability change, and is a special figure high probability normal figure high probability state. That is, “Special Figure C” is 2R compared to “Special Figure A” which is 15R. "Special figure D" is a 2R jackpot symbol called sudden time reduction, and is a special figure low probability normal figure high probability state. That is, “Special Figure D” is 2R compared to “Special Figure B” which is 15R.

  “Special figure E” is a 2R jackpot symbol called hidden probability change, and is a special figure high probability normal figure low probability state. "Special figure F" is a 2R jackpot symbol suddenly called normal, and is a special figure low probability normal figure low probability state. These “special drawing E” and “special drawing F” are both 2R and are in a state in which they do not shift to the time-saving state.

  "Special figure G" is a first small hit symbol, and "Special figure H" is a second small hit symbol, both of which are in a special figure low probability normal figure low probability state. The small hit here is equivalent to the same short hit big hit with 2R. That is, “Special Figure G” and “Special Figure H” are in the same state as “Special Figure F”, but the effects displayed on the decorative symbol display device 208 are different in both cases. By providing “G”, “Special Figure H”, and “Special Figure F”, the interest of the game is enhanced.

  In addition, “Special Figure I” is a first off symbol, and “Special Figure J” is a second off symbol, and the profit amount given to the player is a relatively small profit amount.

  In the pachinko machine 100 of the present embodiment, symbols other than “Special Figure A” are prepared as 15R special jackpot symbols, and the same applies to other symbols such as 15R jackpot symbols.

  FIG. 5B shows an example of a decorative design. There are 10 types of decoration patterns of the present embodiment: “Decoration 1” to “Decoration 10”. The first start port sensor detects that a ball has won the first special figure start port 230 or the second special view start port 232, that is, the ball has entered the first special view start port 230; or On the condition that the second start port sensor detects that a ball has entered the second special symbol start port 232, the left symbol display area 208a, the middle symbol display area 208b, and the right symbol display of the decorative symbol display device 208 are displayed. Displayed in the order of “decoration 1” → “decoration 2” → “decoration 3” →... “Decoration 9” → “decoration 10” → “decoration 1” →... “Decoration display of decorative pattern” is performed.

  When the 15R jackpot of “Special Figure B” is notified, a symbol combination (for example, “decoration 1—decoration 1—decoration”) corresponding to the 15R jackpot corresponding to the 15R jackpot is displayed in the symbol display areas 208a to 208c. 1 ”or“ decoration 2—decoration 2—decoration 2 ”). When notifying 15R special jackpot of “special drawing A”, a combination of three symbols of the same odd number of decorative symbols (for example, “decoration 3—decoration 3—decoration 3” or “decoration 7—decoration 7—decoration 7”). Etc.) is stopped and displayed.

  In addition, the 2R jackpot called “hidden probability change” of “Special Figure E”, the 2R jackpot called “Special Figure F” suddenly, or the first small hit of “Special Figure G”, “Special Figure H” When notifying the second small hit, “decoration 1-decoration 2—decoration 3” is stopped and displayed. Furthermore, in order to notify the 2R jackpot called “sudden change” of “special drawing C” or the 2R jackpot called “sudden time reduction” of “special drawing D”, “decoration 1-decoration 3—decoration 5” is displayed. Stop display.

  On the other hand, when notifying the first deviation of “Special Figure I” and the second deviation of “Special Figure J”, the symbol combinations other than the symbol combinations shown in FIG. 5B are stopped in the symbol display areas 208a to 208c. indicate.

  FIG.5 (c) shows an example of the usual stop display symbol. In the present embodiment, there are two types of stoppage display modes for ordinary maps: “general diagram A” which is a winning symbol and “general symbol B” which is a missed symbol. Based on the fact that the above-mentioned gate sensor has detected that a sphere has passed through the general-purpose start opening 228, the normal symbol display device 210 repeats all lighting of the seven segments and lighting of the central one segment. Perform a “normal change display”. Then, when notifying the winning of the common figure variable game, the “normal figure A” is stopped and displayed, and when notifying the usual figure variable game, the “normal figure B” is stopped and displayed. Also in FIG. 5C, the white portions in the drawing indicate the locations of the segments that are turned off, and the black portions indicate the locations of the segments that are turned on.

<Main control unit main processing>
Next, main control unit main processing executed by the CPU 304 of the main control unit 300 will be described with reference to FIG. This figure is a flowchart showing the flow of main processing of the main control unit.

  As described above, the main control unit 300 is provided with the start signal output circuit (reset signal output circuit) 340 that outputs the start signal (reset signal) when the power is turned on. The CPU 304 of the basic circuit 302 to which this activation signal has been input performs reset start by a reset interrupt, and executes main control unit main processing shown in FIG. 6 in accordance with a control program stored in advance in the ROM 306.

  In step 1001, initial setting 1 is performed. In this initial setting 1, setting of a stack initial value (temporary setting) to the stack pointer (SP) of the CPU 304, setting of an interrupt mask, initial setting of the I / O 310, initial setting of various variables stored in the RAM 308, to the WDT 314 The operation is permitted and the initial value is set. In the present embodiment, a numerical value corresponding to 32.8 ms is set in WDT 314 as an initial value.

  In step 1003, the value of the counter of WDT 314 is cleared, and the time measurement by WDT 314 is restarted.

  In step 1005, whether or not the low voltage signal is on, that is, the voltage value of the power supply that the voltage monitoring circuit 338 supplies from the power management unit 660 to the main control unit 300 is a predetermined value (in this embodiment, 9v), it is monitored whether or not a low voltage signal indicating that the voltage has dropped is output. If the low voltage signal is on (when the CPU 304 detects that the power supply has been cut off), the process returns to step 1003. If the low voltage signal is off (if the CPU 304 has not detected that the power supply has been cut off), the step returns. Proceed to 1007. Even if the predetermined value (9 V) is not yet reached immediately after the power is turned on, the process returns to step 1003 and step 1005 is repeatedly executed until the supply voltage becomes equal to or higher than the predetermined value.

  In step 1007, initial setting 2 is performed. In this initial setting 2, a process for setting a numerical value for determining a cycle for executing a main control unit timer interrupt process, which will be described later, in the counter timer 312 and a predetermined port of the I / O 310 (for example, a test output port, A process of outputting a clear signal from the output port to the first sub control unit 400, a setting for permitting writing to the RAM 308, and the like are performed.

  In step 1009, it is determined whether or not to return to the state before the power interruption (before the power interruption), and the state before the power interruption is not restored (when the basic circuit 302 of the main control unit 300 is set to the initial state). ) Proceeds to the initialization process (step 1013).

  Specifically, first, a RAM clear signal transmitted when a store clerk or the like of a game store operates a RAM clear switch 180 provided on a power supply board is turned on (indicates that there has been an operation). That is, it is determined whether or not the RAM clear is necessary. If the RAM clear signal is on (when the RAM clear is necessary), the process proceeds to Step 1013 to set the basic circuit 302 to the initial state. On the other hand, when the RAM clear signal is OFF (when the RAM clear is not necessary), the power status information stored in the power status storage area provided in the RAM 308 is read, and the power status information is information indicating suspend. It is determined whether or not. If the power status information is not information indicating suspend, the process proceeds to step 1013 to set the basic circuit 302 to an initial state. If the power status information is information indicating suspend, a predetermined area of the RAM 308 is set. A checksum is calculated by adding all the 1-byte data stored in (for example, all areas) to a 1-byte register whose initial value is 0, and the calculated checksum results in a specific value (for example, 0) (whether or not the checksum result is normal). If the checksum result is a specific value (eg, 0) (if the checksum result is normal), the process proceeds to step 1011 to return to the state before the power interruption, and the checksum result is a specific value. If the value is other than 0 (for example, 0) (if the result of the checksum is abnormal), the process proceeds to step 1013 to set the pachinko machine 100 to the initial state. Similarly, if the power status information indicates information other than “suspend”, the process proceeds to step 1013.

  In step 1011, a power recovery process is performed. In this power recovery process, the value of the stack pointer stored in the stack pointer save area provided in the RAM 308 at the time of power failure is read out and reset to the stack pointer (this setting). In addition, the value of each register stored in the register save area provided in the RAM 308 at the time of power interruption is read out and reset in each register, and then the interrupt permission is set. Thereafter, as a result of the CPU 304 executing the control program based on the reset stack pointer and registers, the pachinko machine 100 returns to the state when the power is turned off. That is, the processing is restarted from the instruction next to the instruction (predetermined in step 1015) performed immediately before branching to the timer interrupt processing (described later) immediately before the power interruption. A RAM 308 mounted on the basic circuit 302 in the main control unit 300 shown in FIG. 4 is provided with a transmission information storage area. In this step 1011, a power recovery command is set in the transmission information storage area. This power recovery command is a command indicating that the power has been restored to the state at the time of power-off, and is transmitted to the first sub-control unit 400 in step 2033 in the timer interrupt process of the main control unit 300 described later.

  In step 1013, initialization processing is performed. In this initialization process, interrupt prohibition setting, stack initial value setting to the stack pointer (this setting), initialization of all storage areas of the RAM 308, and the like are performed. Further, here, a normal return command is set in the transmission information storage area provided in the RAM 308 of the main control unit 300. This normal return command is a command indicating that the initialization process (step 1013) of the main control unit 300 has been performed. Like the power recovery command, in step 2033 in the timer interrupt process of the main control unit 300, 1 is transmitted to the sub-control unit 400.

  In step 1015, after setting for prohibition of interruption, the basic random number initial value updating process is performed. In this basic random number initial value update process, two initial value generation random number counters for generating the initial values of the ordinary figure winning random number counter and the special figure random value counter, the ordinary figure timer random number value, and the special figure timer, respectively. Two random number counters for generating each random value are updated. For example, if the range of values that can be taken as a normal timer random number value is 0 to 100, a value is acquired from a random number counter storage area for generating a normal timer random value provided in the RAM 308, and 1 is added to the acquired value. Then, it is stored in the original random number counter storage area. At this time, if the result of adding 1 to the acquired value is 101, 0 is stored in the original random number counter storage area. Other initial value generation random number counters and random number counters are similarly updated. Note that the initial value generation random number counter is also updated in step 2007 to be described later.

  The main control unit 300 repeatedly executes the process of step 1015 except during the timer interrupt process starting at predetermined intervals.

<Main control unit timer interrupt processing>
Next, the main control unit timer interrupt process executed by the CPU 304 of the main control unit 300 will be described with reference to FIG. This figure is a flowchart showing the flow of the main control unit timer interrupt process.

  The main control unit 300 includes a counter timer 312 that generates a timer interrupt signal at a predetermined cycle (in this embodiment, about once every 2 ms), and the main control unit timer interrupt is triggered by this timer interrupt signal. The process is started at a predetermined cycle.

  In step 2001, a timer interrupt start process is performed. In this timer interrupt start process, a process of temporarily saving each register value of the CPU 304 to the stack area is performed.

  In step 2003, the WDT 314 is counted periodically (to prevent detection of processing abnormality) so that the WDT 314 count value exceeds the initial setting value (32.8 ms in the present embodiment) and no WDT interruption occurs. In the embodiment, the restart is performed once every about 2 ms, which is the period of the main control unit timer interrupt.

  In step 2005, input port state update processing is performed. In this input port state update process, the detection signals of various sensors 320 including the above-mentioned front frame door open sensor, inner frame open sensor, lower pan full sensor, and various ball detection sensors are input via the input port of the I / O 310. The input is monitored for the presence or absence of a detection signal, and stored in a signal state storage area provided for each of the various sensors 320 in the RAM 308. If the detection signal of the sphere detection sensor is described as an example, information on the presence / absence of the detection signal of each sphere detection sensor detected in the timer interruption process (about 4 ms before) is stored in the RAM 308 for each sphere detection sensor. This information is read out from the previous detection signal storage area partitioned and stored in the RAM 308 in the previous detection signal storage area partitioned for each sphere detection sensor, and the previous timer interrupt processing (about 2 ms before) ) Is read from the current detection signal storage area provided for each sphere detection sensor in the RAM 308, and this information is read out from the previous detection signal storage area described above. To remember. Further, the detection signal of each sphere detection sensor detected this time is stored in the above-described current detection signal storage area.

  Further, in step 2005, the information on the presence / absence of the detection signal of each sphere detection sensor stored in each storage area of the previous detection signal storage area, the previous detection signal storage area, and the current detection signal storage area is compared. It is determined whether or not the information on the presence or absence of detection signals for the past three times in the ball detection sensor matches the winning determination pattern information. This main control unit timer interrupt process that is repeatedly started at a very short interval of about 2 ms while one game ball passes one ball detection sensor is started several times. For this reason, every time the main control unit timer interrupt process is activated, in step 2005 described above, a detection signal indicating that the same game ball has passed the same ball detection sensor is confirmed. As a result, a detection signal indicating that the same game ball has passed the same ball detection sensor is stored in each of the detection signal storage area, the previous detection signal storage area, and the current detection signal storage area. That is, when the game ball starts to pass through the ball detection sensor, there is no detection signal before, a previous detection signal, and a current detection signal. In the present embodiment, in consideration of erroneous detection of the sphere detection sensor and noise, it is determined that there is a prize when the detection signal is stored twice continuously after no detection signal. The ROM 306 of the main control unit 300 shown in FIG. 4 stores winning determination pattern information (in this embodiment, information indicating that there is no previous detection signal, that there is a previous detection signal, and that there is a current detection signal). In this step 2005, information on the presence / absence of detection signals for the past three times in each ball detection sensor is predetermined winning determination pattern information (in this embodiment, no previous detection signal, previous detection signal, current detection signal present). In the case of the general winning port 226, the variable winning port 234, the first special figure starting port 230, and the second special figure starting port 232, or the ordinary drawing starting port 228. Is determined to have passed. In other words, it is determined that a prize has been awarded to the winning ports 226 and 234 and the starting ports 230, 232, and 228. For example, when the information on the presence / absence of the detection signals for the past three matches with the above-described winning determination pattern information in the general winning opening sensor for detecting the winning at the general winning opening 226, there is a winning at the general winning opening 226. If the information on the presence / absence of detection signals for the past three times does not match the above-described winning determination pattern information, the subsequent general winnings are performed. The process branches to the subsequent process without performing the process associated with winning the prize to the mouth 226. Note that the ROM 306 of the main control unit 300 stores winning determination clear pattern information (in this embodiment, information indicating that there is a detection signal before the previous time, no previous detection signal, and no current detection signal). After it is determined that there has been a single win, it is not determined that there has been a win until the information on the presence or absence of detection signals for the past three times matches the winning determination clear pattern information in each ball detection sensor, and the winning determination is cleared. If it matches the pattern information, it is next determined whether or not it matches the winning determination pattern information.

  In step 2007 and step 2009, basic random number initial value update processing and basic random number update processing are performed. In these basic random number initial value update processing and basic random number update processing, the value of the initial value generation random number counter performed in the above step 1015 is updated, and then used in the main control unit 300. Two random number counters for generating the special figure 1 random value and the special figure 2 random value are updated. For example, if the range of values that can be taken as a random number value for a normal winning number is 0 to 100, a value is acquired from a random number counter storage area for generating a normal winning random number value provided in the RAM 308, and 1 is added to the acquired value. Then, it is stored in the original random number counter storage area. At this time, if the result of adding 1 to the acquired value is 101, 0 is stored in the original random number counter storage area. If it is determined that the random number counter has made one round as a result of adding 1 to the acquired value, the value of the initial value generating random number counter corresponding to each random number counter is acquired and stored in the storage area of the random number counter. set. For example, a value is acquired from a random number counter for generating a regular winning random number that fluctuates in a numerical range of 0 to 100, and a result obtained by adding 1 to the acquired value is stored in a predetermined initial value storage area provided in the RAM 308. If the value is equal to the previously set initial value (for example, 7), the value is acquired as an initial value from the initial value generation random number counter corresponding to the random number counter for generating the random number for winning the normal number, The initial value set this time is stored in the above-described initial value storage area in order to determine that the random number counter for generating the winning random number value has made one round next time, in addition to setting it in the random number counter for generating the winning random value Keep it. Further, apart from the above-described initial value storage area for determining that the random number counter for generating the random number for winning the normal signal has made one round next, it is determined that the random number counter for generating the special figure random number has made one round. An initial value storage area is provided in the RAM 308. In the present embodiment, the counter for acquiring the random number value of FIG. 1 and the counter for acquiring the random value of FIG. 2 are separately provided, but the same counter may be used.

  In step 2011, effect random number update processing is performed. In this effect random number update process, a random number counter for generating an effect random number used by the main control unit 300 is updated.

  In step 2013, timer update processing is performed. In this timer update process, the normal symbol display symbol update timer for timing the time for the symbol to be changed / stopped on the normal symbol display device 210, and the time for the symbol to be changed / stopped to be displayed on the first special symbol display device 212 are timed. Special symbol 1 display symbol update timer for performing, special symbol 2 display symbol update timer for measuring the time for the symbol to be changed and stopped on the second special symbol display device 214, a predetermined winning effect time, a predetermined opening time Various timers including a timer for measuring a predetermined closing time, a predetermined end effect period, and the like are updated.

  In step 2015, winning prize counter updating processing is performed. In this winning opening counter updating process, when winning holes 226, 234 and starting holes 230, 232, 228 are won, the RAM 308 stores the winning ball number storage area provided for each winning hole or for each starting hole. The value is read out, 1 is added, and the original prize ball number storage area is set.

  In step 2017, a winning acceptance process is performed. In this winning acceptance process, it is determined whether or not there has been a winning at the first special figure starting port 230, the second special figure starting port 232, the ordinary drawing starting port 228, and the variable winning port 234. Here, the determination is made using the determination result of whether or not it matches the winning determination pattern information in step 2003. When a winning is made at the first special figure starting port 230 and the corresponding reserved number storage area provided in the RAM 308 is not full, the value is stored in the special counter value storage register of the counter circuit 318. And a value from the random number counter for generating the special figure 1 random value as a special figure 1 random value and storing it in the corresponding random value storage area. When a winning is made to the second special figure starting port 232 and the corresponding reserved number storage area provided in the RAM 308 is not full, the value is sent from the winning counter value storage register of the counter circuit 318 to the special figure 2 winning random number value. And a value from the random number counter for generating the special figure 2 random value as a special figure 2 random value and storing it in the corresponding random value storage area. If there is a win at the general figure starting port 228 and the corresponding reserved number storage area provided in the RAM 308 is not full, the value is obtained as a normal figure winning random number value from the random number counter for generating the normal figure winning random number value. Store in the corresponding random value storage area. When there is a winning at the variable winning opening 234, information indicating that a ball has entered the variable winning opening 234 is stored in the winning storage area for the variable winning opening.

  In step 2019, a payout request number transmission process is performed. Note that the output schedule information and the payout request information output to the payout control unit 600 are composed of, for example, 1 byte, strobe information (indicating that data is set when ON), bit 6 Power-on information (if turned on, indicates that this is the first command transmission after power-on), bits 4-5 indicate the current processing type for encryption (0-3), and bits 0-3 indicate encryption The number of payout requests after processing is shown.

  In step 2021, a normal state update process is performed. This normal state update process performs one of a plurality of processes corresponding to the normal state. For example, in the normal state update process in the middle of the normal symbol display (the above-described general symbol display symbol update timer value is 1 or more), the 7-segment LED constituting the normal symbol display device 210 is repeatedly turned on and off. Turns off drive control. By performing this control, the normal symbol display device 210 performs a usual fluctuation display (ordinary figure fluctuation game).

  Also, in the normal state update process at the timing when the normal symbol change display time has elapsed (the timing when the value of the general symbol display symbol update timer has changed from 1 to 0), if the hit flag is on, the win symbol is displayed. The normal symbol display device 210 is controlled so that the 7-segment LED constituting the normal symbol display device 210 is turned on / off, and when the hit flag is off, the normal symbol display device 210 is configured to be in the off symbol display mode. 7 segment LED on / off drive control is performed. Further, the RAM 308 of the main control unit 300 is provided with a setting area for performing various settings in various processes, not limited to the normal state update process. Here, the above-described lighting / extinguishing drive control is performed, and the setting area is set to indicate that the normal stop display is being performed. By performing this control, the normal symbol display device 210 determines the symbol of either the winning symbol (the common symbol A shown in FIG. 5C) or the off symbol (the common symbol B shown in FIG. 5C). Display. Thereafter, information indicating the stop period is set in a storage area of a normal stop time management timer provided in the RAM 308 in order to maintain the display for a predetermined stop display period (for example, for 500 ms). With this setting, the symbol that has been confirmed and displayed is stopped and displayed for a predetermined period, and the player is notified of the result of the normal game.

  Further, if the result of the usual figure variable game is a hit, the usual figure hit flag is turned on as will be described later. When the usual figure hit flag is on, in the usual figure state update process at the timing when the predetermined stop display period ends (when the usual figure stop time management timer value changes from 1 to 0), The normal operation is set in the setting area, and the blade member 232a is held in the open state by the solenoid 332 for opening and closing the blade member 232a of the second special drawing start port 232 for a predetermined opening period (for example, 2 seconds). In addition, a signal indicating the open period is set in the storage area of the blade open time management timer provided in the RAM 308.

  Further, in the usual state update process that starts at the timing when the predetermined opening period ends (the timing when the value of the blade opening time management timer changes from 1 to 0), the blade member for a predetermined closing period (for example, for 500 ms) A signal for holding the blade member in the closed state is output to the opening / closing drive solenoid 332, and information indicating the closing period is set in the storage area of the blade closing time management timer provided in the RAM 308.

  Further, in the normal state update process that starts at the timing when the predetermined closing period ends (when the value of the blade closing time management timer is changed from 1 to 0), the non-operating state is set in the setting area of the RAM 308. To do. Furthermore, if the result of the usual figure fluctuation game is out, the usual figure out flag is turned on as will be described later. When the off-normal flag is on, the normal state update process at the timing when the predetermined stop display period described above ends (the timing at which the normal stop time management timer value changes from 1 to 0) In the setting area of the RAM 308, normal operation inactive is set. In the general state update process in the case where the general map is not in operation, the process proceeds to the next step 2023 without doing anything.

  In step 2023, a general drawing related lottery process is performed. In this general map-related lottery process, the open / close control of the general map variable game and the second special map start port 232 is not performed (the state of the general map is not in operation), and the pending general map variable game is not held. When the number is 1 or more, it is decided whether to win or not to win the result of the variable figure game by random lottery based on the random number value stored in the random number value storage area. When the winning judgment is made and the winning is made, the winning flag provided in the RAM 308 is set to ON. If unsuccessful, turn off the winning flag. Regardless of the result of the hit determination, next, the value of the random number counter for generating the normal figure timer random value is acquired as the normal figure timer random value, and a plurality of variable times are obtained based on the acquired normal figure timer random value. One time is selected for variably displaying the normal map on the general map display device 210, and this variable display time is stored as a normal map variable display time in a general map variable time storage area provided in the RAM 308. In addition, the number of pending general figure variable games is stored in the usual figure pending number storage area provided in the RAM 308, and from the number of pending custom figure variable games each time a hit determination is made. The value obtained by subtracting 1 is re-stored in the usual figure number-of-holds storage area. Also, the random number value used for the hit determination is deleted.

  Next, the special figure state update process for each of the special figure 1 and the special figure 2 is performed. First, the special figure state update process (the special figure 2 state update process) for the special figure 2 is performed (step 2025). In the special figure 2 state update process, one of the following eight processes is performed in accordance with the state of the special figure 2. For example, in the special figure 2 state update process in the middle of the special figure 2 fluctuation display (the value of the above-mentioned special figure 2 display symbol update timer is 1 or more), the 7-segment LED constituting the second special symbol display device 214 is turned on. Performs lighting / extinguishing drive control that repeatedly turns off. By performing this control, the second special symbol display device 214 performs the variable display of the special figure 2 (special figure 2 variable game).

  In addition, predetermined transmission information indicating that the rotation start setting transmission process is executed in the command setting transmission process (step 2033 described later) is additionally stored in the above-described transmission information storage area, and then the process ends.

  Further, the RAM 308 of the main control unit 300 includes a 15R big hit flag, 2R big hit flag, first small hit flag, second small hit flag, first off flag, second off flag, special figure probability variation flag, and normal A flag for each probability variation flag is prepared. In the special figure 2 state update process starting at the timing when the special figure 2 fluctuation display time has elapsed (the timing when the special figure 2 display symbol update timer value has changed from 1 to 0), the 15R big hit flag is on, and the special figure probability fluctuation When the flag is also on and the normal figure probability fluctuation flag is on, the special figure A, 15R jackpot flag shown in FIG. 5A is on, the special figure probability fluctuation flag is off, and the common figure probability fluctuation flag is on. When the special figure B, 2R big hit flag is on, the special figure probability fluctuation flag is on, and the general figure probability fluctuation flag is also on, the special figure C, 2R big hit flag is on, the special figure probability fluctuation flag is off, When the probability fluctuation flag is on, the special figure D, 2R jackpot flag is on, the special figure probability fluctuation flag is on, and when the common figure probability fluctuation flag is on, the special figure E, 2R jackpot flag is on, special chart Probability flag is off, normal When the rate fluctuation flag is also off, the special figure F, when the first small hit flag is on, the special figure G, when the second small hit flag is on, the special figure H, and the first off flag are on. In such a case, the 7-segment LED constituting the second special symbol display device 214 is controlled to be turned on / off so that the special figure I and the second off-flag are turned on, respectively, so that the special figure J is in the respective mode. A setting indicating that the special figure 2 stop display is in progress is made in the setting area of the RAM 308. By performing this control, the second special symbol display device 214 has a 15R special jackpot symbol (special symbol A), a 15R jackpot symbol (special symbol B), a sudden probability variation symbol (special symbol C), and a sudden time-short symbol symbol (special symbol). D), hidden probability variation (special E), suddenly normal (special F), first small hit (special G), second small hit (special H), first off symbol (special) Any one of the symbols I) and the second off-set symbol (special symbol J) is confirmed and displayed. Thereafter, information indicating the stop period is set in the storage area of the special figure 2 stop time management timer provided in the RAM 308 in order to maintain the display for a predetermined stop display period (for example, for 500 ms). With this setting, the specially displayed special figure 2 is stopped and displayed for a predetermined period, and the result of the special figure 2 variable game is notified to the player. In addition, if the time reduction number stored in the time reduction number storage unit provided in the RAM 308 is 1 or more, 1 is subtracted from the time reduction number, and if the subtraction result becomes 1 to 0, the special figure probability is changing. If not (details will be described later), the time reduction flag is turned off. Further, the hourly flag is also turned off during the big hit game (in the special game state).

  In addition, a predetermined transmission information indicating that the rotation stop setting transmission process is executed in the command setting transmission process (step 2033 described later) is additionally stored in the above-described transmission information storage area, and the design for stopping the variable display is special. 2 is additionally stored in the RAM 308 as information to be included in command data, which will be described later, and the process ends.

  If the result of the special figure 2 variable game is a big hit, the big hit flag is turned on as will be described later. When the jackpot flag is on, in the special figure 2 state update process at the timing when the predetermined stop display period ends (the timing when the special figure 2 stop time management timer value changes from 1 to 0), the RAM 308 In the setting area, the special figure 2 is in operation and waits for a predetermined winning effect period (for example, 3 seconds), that is, a period during which an image for notifying the player that the big win by the decorative symbol display device 208 is started is displayed. Therefore, information indicating the winning effect period is set in the storage area of the special figure 2 standby time management timer provided in the RAM 308. Further, predetermined transmission information indicating that the winning effect setting transmission process is executed in the command setting transmission process (step 2033 described later) is additionally stored in the transmission information storage area.

  Further, in the special figure 2 state update process that starts at the timing when the predetermined winning effect period ends (the timing when the value of the special figure 2 standby time management timer changes from 1 to 0), a predetermined release period (for example, 29 seconds) Alternatively, the door member 234a is held open by the solenoid 332 for opening and closing the door member 234a of the variable prize opening 234 until a winning of a predetermined number of balls (for example, 10 balls) is detected at the variable prize opening 234. A signal indicating the opening period is set in the storage area of the door opening time management timer provided in the RAM 308. Further, predetermined transmission information indicating that the special winning opening release setting transmission processing is executed in the command setting transmission processing (step 2033 described later) is additionally stored in the transmission information storage area.

  In the special figure 2 state update process that starts at the timing when the predetermined opening period ends (the timing when the door opening time management timer value changes from 1 to 0), the predetermined closing period (for example, 1.5 seconds) A signal for holding the door member 234a in the closed state is output to the solenoid 332 for opening and closing the door member 234a of the variable prize opening 234, and the closing period is indicated in the storage area of the door closing time management timer provided in the RAM 308. Set the information. In addition, predetermined transmission information indicating that the special winning opening closing setting transmission process is executed in the command setting transmission process (step 2033 described later) is additionally stored in the transmission information storage area.

  In addition, in the special figure 2 state update process that starts at the timing when the door member opening / closing control is repeated a predetermined number of times (15 rounds or 2 rounds in this embodiment) and finished, a predetermined end effect period (for example, 3 seconds) In other words, the effect standby period is stored in the storage area of the effect standby time management timer provided in the RAM 308 in order to set to wait for a period during which an image for informing the player that the big hit by the decorative symbol display device 208 is to be ended is displayed. Set the information indicating. Also, if the normal probability fluctuation flag is set to ON, at the same time as the end of the jackpot game, the time reduction number 100 is set in the time reduction number storage unit provided in the RAM 308, and the time reduction flag provided in the RAM 308 is set. Turn on. If the usual time probability variation flag is set to OFF, the time reduction number is not set in the time reduction number storage unit, and the time reduction flag is not turned ON. The short time here means that the pachinko machine is in an advantageous state for the player in order to shorten the time from the end of the big hit in the special figure variable game to the start of the next big hit. If the short time flag is set to ON at this time, it is a normal high probability state. There is a higher probability of hitting a general-purpose variable game in the high-probability state than in the low-probability state. In addition, the fluctuation time of the normal figure variable game and the fluctuation time of the special figure variable game are shorter in the normal figure high probability state than in the normal figure low probability state. Further, in the normal high-probability state, the opening time in one opening of the pair of blade members 232a of the second special figure starting port 232 tends to be longer than in the normal low-probability state. In addition, the pair of blade members 232a are more likely to open in the normal high probability state than in the normal low probability state. In addition, as described above, the hourly flag is set to off during the big hit game (in the special game state). Therefore, the normal low probability state is maintained during the jackpot game. This is because, if the game is in a high probability state during a jackpot game, a large number of games will be placed in the second special figure start port 232 until a predetermined number of game balls are entered during the jackpot game. There is a problem that a ball enters and the number of game balls that can be acquired during the jackpot increases, resulting in an increase in euphoria. This is to solve this problem.

  Further, predetermined transmission information indicating that the end effect setting transmission process is executed in the command setting transmission process (step 2033 described later) is additionally stored in the transmission information storage area.

  In the special figure 2 state update process that starts at the timing when the predetermined end production period ends (the timing when the production standby time management timer value changes from 1 to 0), the special figure 2 is not activated in the setting area of the RAM 308. Set medium. Further, if the result of the special figure 2 variable game is out of the way, the off flag is turned on as will be described later. In the case where the miss flag is on, even in the special figure 2 state update process at the timing when the predetermined stop display period described above ends (the timing when the special figure 2 stop time management timer value changes from 1 to 0), In the setting area of the RAM 308, special figure 2 inactive is set. In the special figure 2 state update process in the case where the special figure 2 is not in operation, the process proceeds to the next step 2027 without doing anything.

  Subsequently, special figure state update processing (special figure 1 state update process) for special figure 1 is performed (step 2027). In the special figure 1 state update process, each process described in the special figure 2 state update process is performed according to the state of the special figure 1. Each process performed in the special figure 1 state update process is the same as the process in which “special figure 2” in the contents described in the special figure 2 state update process is replaced with “special figure 1”. Omitted. The order of the special figure 2 state update process and the special figure 1 state update process may be reversed.

  When the special figure state update process in step 2025 and step 2027 is completed, a special figure-related lottery process for each of special figure 1 and special figure 2 is performed. Also here, the special figure related lottery process (special figure 2 related lottery process) for special figure 2 is performed first (step 2029), and then the special figure related lottery process for special figure 1 (special figure 1 related lottery process). (Step 2031). Also for these special drawing related lottery processes, the main control unit 300 performs the special figure 2 related lottery processing before the special figure 1 related lottery processing, so that the special figure 2 variable game start condition and the special figure 1 fluctuation Even if the game start conditions are satisfied at the same time, since the special figure 2 variable game is changing first, the special figure 1 variable game does not start changing. Further, the notification of the result of the jackpot determination of the special figure variable game by the decorative symbol display device 208 is performed by the first sub-control unit 400, and the lottery result of the lottery based on the winning at the second special figure starting port 232 is notified. However, it is performed in preference to the notification of the lottery result of the lottery based on the winning at the first special figure starting port 230.

  In step 2033, command setting transmission processing is performed, and various commands are transmitted to the first sub-control unit 400. The output schedule information to be transmitted to the first sub-control unit 400 is composed of 16 bits, for example, bit 15 is strobe information (indicating that data is set when ON), bits 11 to 14 are Command type (In this embodiment, command types such as basic command, symbol variation start command, symbol variation stop command, winning effect start command, end effect start command, jackpot round number designation command, power recovery command, RAM clear command are specified. Possible information), bits 0 to 10 are composed of command data (predetermined information corresponding to the command type).

  Specifically, the strobe information is turned on and off in the command setting transmission process described above. If the command type is a symbol variation start command, information indicating the value of the 15R jackpot flag or 2R jackpot flag, the value of the special figure probability variation flag, the timer number selected in the special figure related lottery process, etc. is included in the command data. In the case of the symbol variation stop command, the value of the 15R jackpot flag, 2R jackpot flag, the value of the special figure probability variation flag, etc. are included. In the case of a jackpot round number designation command, the value of the special variation probability flag, the number of jackpot rounds, and the like are included.

<Appendix>
The present invention described above is
1. A circuit board (for example, the circuit board 700) on which a control circuit for controlling the game is mounted;
A board housing member (for example, a board case 701) for housing the circuit board;
A conductive earth member (eg, sheet metal 702);
A conductive member (for example, a harness 708) for electrically connecting the ground portion of the circuit board and the ground member;
A game machine equipped with
The substrate housing member is formed so as to cover the bottom side of the circuit board (for example, the surface opposite to the component mounting surface),
The ground member is provided on the bottom side of the circuit board,
One end of the conductive member (for example, the connector 709) is connected to the ground portion of the circuit board, and the other end (for example, the ground plate 710) of the conductive member is sandwiched between the substrate housing member and the ground member. By connecting to the ground member, the ground of the circuit board and the ground member are made conductive.
Because it is a game stand characterized by that,
In some cases, grounding, that is, ground connection is easy, and the efficiency of assembly work is improved.

  Further, according to the present invention, when an illegal act such as an electromagnetic wave got that causes the game machine to perform an illegal operation using electromagnetic waves is performed, or when an electronic component fails, for example, the ground member is charged. Then, current flows from the conductive member to the circuit board, and electronic components on the circuit board break down or abnormal operation (for example, audio disturbance, image disturbance, malfunction of an accessory, etc.), which causes a game shop clerk. However, it may be easy to notice fraud and electronic component failures.

  In addition, according to the present invention, the portion where the conductive member is sandwiched between the board housing member and the ground member has heat, and thus the malfunction of the electronic component may be induced from the back side of the circuit board.

  The ground portion of the circuit board and one end of the conducting member may be connected by a connector. According to this connector connection, disconnection of the connector can be easily confirmed, and it may be possible to prevent a go-to action.

  Further, the conducting member may be a plurality of signal lines that connect one end to the other end.

  In some cases, the signal line of the conductive member is connected so as to go around from the periphery of the circuit board.

  Further, one end of the conductive member may be provided on the mounting surface of the circuit board.

  Also, one end of the conducting member may be provided at the end of the circuit board.

  Further, the other end of the conductive member may be made of a material that can be elastically deformed. In some cases, the other end of the conductive member is elastically deformed and connected to the ground member, so that the ground can be more reliably grounded.

  By the way, the “board housing member” may be, for example, a board case that houses a circuit board, and the member that supports the circuit board may be this “board housing member” or another member. Further, the “board housing member” does not have to be a case that covers the entire surface of the circuit board, but may be between the circuit board and the ground member. Further, the “substrate housing member” does not need to be an insulating material (an insulating sheet may be provided only at a portion where the substrate housing member and one end of the conducting member are in contact).

  Further, the “earth member” may be a sheet metal, for example. Further, the “earth member” may be a noise countermeasure component (shield member) of the liquid crystal substrate. In addition, the “ground member” may be a cabinet (constituted with conductivity, with a conductive sheet attached) in the case where the game machine is a slot machine.

  Further, the “conducting member” may be a ground wire, for example.

  Further, the “bottom side of the circuit board” may be a solder surface on the back side of the mounting surface in the case of a circuit board mounted on one side, for example.

The present invention also provides
2. 1. In the game table described in
Having a protrusion at the other end of the conducting member;
The substrate housing member has a hole,
The other end of the conducting member is sandwiched between the substrate housing member and the ground member, and the ground member is fitted to the projection of the other end and the hole of the substrate housing member. By connecting, the ground of the circuit board and the earth member are made conductive.
Because it is a game stand characterized by that,
In some cases, the conductive member can be prevented from coming out of the substrate housing member and can be more reliably grounded.

  In addition, if it is a fraudster, as described above, according to the present invention, an abnormal operation is caused by an electromagnetic wave and the game store clerk finds it. Therefore, to avoid this, it is necessary to remove the conductive member from the board housing member. Although it thinks, since the conduction member is made difficult to come off from the substrate housing member, this may not be achieved and it may be possible to give up the goto action. In addition, a fraudulent person may consider removing one end of the conductive member from the circuit board, but the game machine of the present invention may be configured not to provide an empty terminal (empty connection portion) when it is normal. In this case, if one end of the conductive member is removed from the circuit board, an empty terminal (empty connection portion) is generated, which may allow the game shop clerk to find the goto action.

  In some cases, the substrate housing member has a recess, and one end of the conductive member is fitted in the recess. In this case, it may be more difficult to remove the conducting member from the substrate housing member.

  Further, the present invention may have a configuration in which the other end of the conductive member has a plurality of signal lines, and the width of the other end is wider than the width of the plurality of signal lines. In this case, the conductive member may be more difficult to be removed from the substrate housing member due to the wide width.

  The “hole” may be a through hole or a hole that does not pass through.

  The “fitting” may be a tight fitting or a loose fitting with a space.

The present invention also provides
3. 1. Or 2. In the game table described in
The other end of the conductive member is connected to the ground member at a position where it is not visible or difficult from the circuit board side.
Because it is a game stand characterized by that,
If it is a fraudster, as described above, according to the present invention, an abnormal operation is caused by an electromagnetic wave and the game shop clerk finds it, so it is considered to remove the conductive member from the board housing member in order to avoid this. Because the other end of the conductive member is connected to the ground member at a position where it is not visible or difficult, it is difficult to remove the location, or it is difficult to remove it. There are cases where it is possible.

  In addition, the fact that the connection position between the other end of the conducting member and the ground member is invisible is that the connection position of the other end and the ground member is difficult to make direct contact. During maintenance, you may be less likely to get hurt by accidentally touching it.

The present invention also provides
1. Or 2. In the game table described in
The other end of the conducting member is connected to the ground member at a position inside the periphery of the circuit board.
There may be a gaming table characterized by this. As a result, the other end of the conducting member may be connected to the ground member at a position where it is not visible or difficult from the circuit board side.

The present invention also provides
1. Or 2. In the game table described in
The position of one end of the conducting member and the position of the other end are shifted in the horizontal direction or the vertical direction on the circuit board,
There may be a gaming table characterized by this.

  The “invisible or difficult position” may be, for example, a position entering from the periphery of the circuit board. Further, since the circuit board is made of a non-transparent member, the back side of the circuit board may be “invisible or difficult position”.

  According to the present invention, since the grounding is easy, the assembly efficiency may be improved.

  According to the present invention, when there is a fraudulent act such as an electromagnetic wave got or a failure of an electronic component, the ground member is charged, and current flows from the ground member to the circuit board through the conductive member, and the electronic circuit on the circuit board. There are cases in which a component malfunctions or abnormally operates (for example, sound disturbance, image disturbance, malfunction of an accessory, etc.), which may make it easier for a game clerk to notice fraud or electronic component failure.

In some cases, the member cannot be visually recognized, and the position thereof is unknown and cannot be removed or difficult to remove.

  According to the present invention, there is a case where the operator is less likely to be injured during the maintenance because the conductive member is in a position where it is difficult to make a direct contact due to invisibility or the like.

  In addition, according to the present invention, the continuity between the ground wiring pattern of the circuit board and the ground member may be reliably ensured by the continuity member, and when checking whether there are any abnormalities in the electrical components of the circuit board. In addition, since a connection state between the second connector connected to the ground wiring pattern of the circuit board and the first connector connected to the ground member can be confirmed, a more reliable conduction state may be secured. .

<Description of each configuration>
The configuration of the present invention will be described.

<< About the first member >>

[04] The first member may be a sheet metal in the vicinity of the upper plate provided in the front frame door part, and any member on the door body side (for example, in the vicinity of the upper plate provided in the front frame door part) Sheet metal) or any member on the frame side.
[05] The first member may be a conductive member (for example, a tank rail) connected to the frame ground instead of the sheet metal.
[06] The first member may be more resistant to bending than the second member or the third member, may be thicker, and may be stronger even if it is thin.
[07] In some cases, the first member is flat at least in contact with the second member.
[08] The first member may be raised at a predetermined location (for example, a location in contact with the second member).
[09] The first member may not be parallel to the third member, and may be parallel. In the case of being parallel, the contact area may be increased.
[10] The first member may contact the third member (for example, the substrate case) via the second member (for example, the ground plate), and may directly contact the third member. (At least a part of the contact) may not directly contact the third member.
[11] The first member may sandwich a predetermined member other than the second member, and the predetermined member other than the second member may be screwed. Moreover, there may be a predetermined member between the first member and the third member (for example, a harness passes).
[12] The first member may be positioned in a vertical direction with respect to a predetermined member provided on the game board side or the main body side, and with respect to the predetermined member provided on the game board side or the main body side. May be located horizontally.
[13] In addition to the circuit board, a sheet metal may be accommodated in the board case. The sheet metal in the substrate case may be connected to ground (for example, connected to the ground region of the substrate, and may be connected to FG), and may play a role of noise shielding.
[14] There may be a plurality of first members (for example, sheet metal). There may be a location where the first members overlap. In some cases, the first members do not overlap with each other, for example, a hole is formed and the third member is exposed.
[15] The size of the first member (for example, sheet metal) may be larger than that of the second member (for example, ground plate), and may be the same as the second member (for example, ground plate). It may be smaller than the second member (eg, ground plate), may be larger than the third member (eg, substrate case), may be the same as the third member (eg, substrate case), and It may be smaller than the member (for example, substrate case). In addition, the first member (for example, a sheet metal) may overlap with the entire second member (for example, an earth plate), may overlap with a part of the second member (for example, an earth plate), It may overlap with the entire member (for example, the substrate case), and may overlap with a part of the third member (for example, the substrate case).
[16] The first member (for example, sheet metal) may be fixed, integrated, or detachably disposed on a predetermined member provided on the game board side or the main body side [17]. On the sheet metal side, there is a deformable portion (elastic deformation, plastic deformation) like an earth plate.

<< About the second member >>

[02] A portion (for example, a curved portion) of the second member that comes into contact with the first member (for example, a sheet metal) is pressed against the first member to increase a contact area with the first member. That is, the contact area may be variable depending on how the second member and the first member are fixed.
[03] When the second member is mounted at a position other than the normal mounting position, unlike the normal function in which the curved portion is elastically deformed, any part may be plastically deformed or the metal may be deformed due to abnormal stress. Fatigue may accelerate or break. That is, if the mounting method of the second member is wrong (for example, if it is removed by a fraudulent person and is mounted incorrectly when it is mounted again), the gaming table will operate normally due to damage to the second member. This may result in fraud.
[04] The conducting wire connected to the second member may be flexible and may not be flexible. The second member may be thicker than the conducting wire.
[05] The height of the second member (the length of the portion sandwiched between the first member and the third member) is determined from the point where the third member and the second member are in contact with each other. It is higher than the height to the location closest to the first member among the members. When the positioning member for positioning the second member in the third member is provided separately from the third member, the height of the second member (the first member and the third member) The length of the portion sandwiched between the members) is the height from the position where the third member and the second member are in contact to the position closest to the first member among the third members including the positioning portion. Higher than that.
[06] The height of the second member (the length of the portion sandwiched between the first member and the third member) is determined from the location where the third member and the second member are in contact with each other. It is higher than the distance to the location closest to the third member among the members. When the positioning member for positioning the second member in the third member is provided separately from the third member, the height of the second member (the first member and the third member) The length of the portion sandwiched between the members) is the distance from the location where the third member and the second member are in contact to the location closest to the third member including the positioning portion of the first member Higher than.
