Next, the payout control unit 600, the launch control unit 630, and the power supply control unit 660 of the pachinko machine 100 will be described.

  The payout control unit 600 controls the payout motor 602 of the payout device 152 mainly based on a command signal or the like transmitted from the main control unit 300, and a prize ball or a rental ball based on a control signal output from the payout sensor 604 It is detected whether or not the payout has been completed, and communication with a card unit 608 provided separately from the pachinko machine 100 is performed via the interface unit 606.

<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 “variable display of special figure 1” and “variable display of special figure 2” correspond to an example of a symbol variable display. Then, when the variation time determined before the start of the fluctuation of the special figure 1 elapses, the first special symbol display device 212 stops and displays the stop symbol form of the special figure 1, and the fluctuation time determined before the start of the fluctuation of the special figure 2 When elapses, the second special symbol display device 214 stops and displays the stop symbol form of the special symbol 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 the stop display corresponds to an example of the symbol variation stop display, hereinafter, a series of processes from the start of the “variable display of the special figure 1 or 2” until the stop symbol form of the special figure 1 or 2 is stopped and displayed. The display 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 the difference in 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. 3B 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 SA01, 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 SA03, the counter value of WDT 314 is cleared, and the time measurement by WDT 314 is restarted.

  In step SA05, whether or not the low voltage signal is on, that is, the voltage value of the power source supplied from the power source control unit 660 to the main control unit 300 by the voltage monitoring circuit 338 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 is cut off), the process returns to step SA03. If the low voltage signal is off (if the CPU 304 does not detect that the power supply is cut off), the step returns. Proceed to SA07. Even if the predetermined value (9 V) is not yet reached immediately after the power is turned on, the process returns to step SA03, and step SA05 is repeatedly executed until the supply voltage becomes equal to or higher than the predetermined value.

  In step SA07, 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 SA09, 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 an initialization process (step SA13).

  Specifically, first, a RAM clear signal transmitted when a store clerk or the like of an amusement store operates the RWM clear switch 180 provided on the power supply board is turned on (indicates that there has been an operation). That is, it is determined whether or not RAM clear is necessary. If the RAM clear signal is on (RAM clear is necessary), the process proceeds to step SA13 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 SA13 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 SA11 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 SA13 to set the pachinko machine 100 to the initial state. Similarly, when the power status information indicates information other than “suspend”, the process proceeds to step SA13.

  In step SA11, power recovery processing 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 SA15) 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 step SA11, 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 interruption, and is transmitted to the first sub control unit 400 in step SB33 in the timer interrupt process of the main control unit 300, which will be described later.

  In step SA13, 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 SA13) of the main control unit 300 has been performed. Like the power recovery command, the normal return command is the first command in step SB33 in the timer interrupt process of the main control unit 300. 1 is transmitted to the sub-control unit 400.

  In step SA15, after setting for prohibition of interruption, a basic random number initial value update 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. The initial value generation random number counter is also updated in step SB07 described later.

  The main control unit 300 repeatedly executes the process of step SA15 except during a timer interrupt process that starts every predetermined period.

<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 SB01, timer interrupt start processing 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 SB03, the WDT is periodically updated (so that the count value of the WDT 314 exceeds the initial setting value (32.8 ms in the present embodiment) and no WDT interrupt occurs (so as not to detect a processing abnormality). 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 SB05, 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.

  In step SB05, the information on the presence / absence of the detection signal of each sphere detection sensor stored in each storage area of the 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 interruption process is started, in the above-described step SB05, 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 SB05, information on presence / absence of detection signals for the past three times in each sphere 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 SB07 and step SB09, a basic random number initial value update process and a basic random number update process 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 step SA15 is updated, and then the normal winning random number value 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 SB11, 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 SB13, 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 SB15, 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 SB17, 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 SB03. 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 the 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 SB19, 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 SB21, 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, 500 msec). 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 opened to the solenoid (332) for opening and closing the blade member 232a of the second special figure starting port 232 for a predetermined opening period (for example, 2 seconds). And a signal indicating the open period is set in the storage area of the blade open time management timer provided in the RAM 308.

  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 is changed from 1 to 0), the blade member has a predetermined closing period (for example, 500 milliseconds). 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, nothing is done and the process proceeds to the next step SB23.

  In step SB23, 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.

  Subsequently, 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 SB25). 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 to be executed in the command setting transmission process (step SB33) is additionally stored in the transmission information storage area, and the process ends.

  Further, the RAM 308 of the main control unit 300 includes a 15R big hit flag, a 2R big hit flag, a first small hit flag, a second small hit flag, a first off flag, a second off flag, a special figure probability variation flag, and a normal figure. 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 I 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 first off-set symbol (special symbol J) is confirmed and displayed. After that, 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, 500 milliseconds). 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).

  Further, the special transmission information indicating that the rotation stop setting transmission process is executed in the command setting transmission process (step SB33) is additionally stored in the above-described transmission information storage area, and the design for stopping the variable display is shown in FIG. The special figure 2 identification information indicating the presence is additionally stored in the RAM 308 as information to be included in command data, which will be described later, and the processing is terminated.

  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 SB33) 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 opened to 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. In addition to outputting a signal to be held at the same time, information indicating the opening period is set in the storage area of the door opening time management timer provided in the RAM 308. In addition, predetermined transmission information indicating that the special winning opening release setting transmission process is executed in the command setting transmission process (step SB33) 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 a closed state is output to a solenoid (332) for opening and closing the door member 234a of the variable prize opening 234, and a closing period is stored in a storage area of a door closing time management timer provided in the RAM 308. Set the information indicating. In addition, predetermined transmission information indicating that the special winning opening closing setting transmission process is executed in the command setting transmission process (step SB33) is additionally stored in the transmission information storage area.

  In addition, the opening / closing control of the door member is repeated a predetermined number of times (in this embodiment, 15 rounds or 2 rounds), and in the special figure 2 state update process that starts at the end timing, 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 start 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 SB33) is additionally stored in the transmission information storage area.

  Also, in the special figure 2 state update process that starts at the timing when the predetermined end production period ends (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 when the special figure 2 is not operating, nothing is done and the process proceeds to the next step SB27.

  Subsequently, special figure state update processing (special figure 1 state update process) for special figure 1 is performed (step SB27). 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 SB25 and step SB27 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 SB29), and then the special figure related lottery process for special figure 1 (special figure 1 related lottery process) (Step SB31).

  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 SB33, 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 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. When the command type indicates a basic command, device information in the command data, presence / absence of winning at the first special figure starting port 230, presence / absence of winning at the second special figure starting port 232, winning of the variable winning port 234 Includes presence or absence.

  In the rotation start setting transmission process described above, the 15R jackpot flag or 2R jackpot flag value, the special figure probability variation flag value, the special figure 1 related lottery process, and the special figure 2 relation stored in the RAM 308 as command data. Information indicating the timer number selected in the lottery process, the number of the first special figure variable game or the second special figure variable game held, etc. is set.

  In the rotation stop setting transmission process described above, information indicating the value of the 15R jackpot flag, the 2R jackpot flag, the value of the special figure probability variation flag, etc. stored in the RAM 308 is set in the command data. In the winning effect setting transmission process described above, the command control data stored in the RAM 308, the effect control information output to the decorative symbol display device 208, various lamps 418, and the speaker 120 during the winning effect period, the special figure probability variation flag Information indicating the value, the number of the first special figure variable game or the second special figure variable game being held, etc. is set. In the above-described end effect setting transmission process, the command control data stored in the RAM 308, the effect control information output to the decorative symbol display device 208, various lamps 418, and the speaker 120 during the effect standby period, the special figure probability variation flag Information indicating the value, the number of the first special figure variable game or the second special figure variable game being held, etc. is set.

  In the above-described large winning opening release setting transmission process, the number of big hits stored in the RAM 308 in the command data, the value of the special figure probability variation flag, the pending first special figure variation game or the second special figure variation game is stored. Set information such as number. In the above-mentioned big winning opening closing setting transmission process, the number of big hits stored in the RAM 308 in the command data, the value of the special figure probability variation flag, the pending first special figure variation game or the second special figure variation game is stored. Set information such as number. In step SB33, general command special figure hold increase processing is also performed. In this general command special figure pending increase process, special figure identification information (information showing special figure 1 or special figure 2) stored in the transmission information storage area of the RAM 308, command notice information (preliminary notice information, false) Set either advance notice information or no advance notice information).

  In the first sub-control unit 400, it is possible to determine the production control according to the change of the game control in the main control unit 300 by the command type included in the received output schedule information, and it is included in the output schedule information. Based on the information of the command data, the contents of effect control can be determined.

  In step SB35, an external output signal setting process is performed. In this external output signal setting process, the game information stored in the RAM 308 is output to the information input circuit 350 separate from the pachinko machine 100 via the information output circuit 336.

  In step SB37, device monitoring processing is performed. In this device monitoring process, the signal states of the various sensors stored in the signal state storage area in step SB05 are read, and the presence or absence of a predetermined error, for example, the presence or absence of a front frame door opening error or the bottom pan full error is monitored. When the front frame door opening error or the lower pan full error is detected, the transmission information to be transmitted to the first sub-control unit 400 includes device information indicating the presence or absence of the front frame door opening error or the lower pan full error. Set. Further, various solenoids 332 are driven to control the opening and closing of the second special figure starting port 232 and the variable prize opening 234, and the normal symbol display device 210 and the first special symbol display via the display circuits 324, 326 and 330. Display data to be output to the device 212, the second special symbol display device 214, the various status display units 328, and the like is set in the output port of the I / O 310. Further, the output schedule information set in the payout request number transmission process (step SB19) is output to the first sub-control unit 400 via the output port (I / O 310).

  In step SB39, it is monitored whether or not the low voltage signal is on. Then, when the low voltage signal is on (when power supply cutoff is detected), the process proceeds to step SB43. When the low voltage signal is off (power supply cutoff is not detected), the process proceeds to step SB41.

  In step SB41, a timer interrupt end process is performed. In this timer interrupt end process, the value of each register temporarily saved in step SB01 is set in each original register, interrupt permission is set, etc., and then the main control unit main process shown in FIG. Return to.

  On the other hand, in step SB43, a specific variable or stack pointer for returning to the power-off state at the time of power recovery is saved as a return data in a predetermined area of the RAM 308, and power-off processing such as initialization of input / output ports is performed. After that, the process returns to the main process of the main control unit shown in FIG.

<Processing of First Sub-Control Unit 400>
The process of the first sub control unit 400 will be described with reference to FIG. FIG. 5A is a flowchart of main processing executed by the CPU 404 of the first sub control unit 400. FIG. 5B is a flowchart of the strobe interrupt process of the first sub control unit 400. FIG. 6C is a flowchart of the timer variable update interrupt process of the first sub control unit 400. FIG. 4D is a flowchart of the image control process of the first sub control unit 400.

  First, in step SC01 in FIG. 9A, various initial settings are performed. When power is turned on, an initialization process is first executed in SC01. In this initialization processing, initialization of input / output ports, initialization processing of a storage area in the RAM 408, and the like are performed.

  In step SC03, it is determined whether or not the timer variable is 10 or more. This process is repeated until the timer variable becomes 10. When the timer variable becomes 10 or more, the process proceeds to step SC05.

  In step SC05, 0 is assigned to the timer variable. In step SC07, command processing is performed. The CPU 404 of the first sub control unit 400 determines whether a command has been received from the main control unit 300. In step SC09, an effect control process is performed. For example, when there is a new command in SC07, the effect data corresponding to this command is read from the ROM 406, and the effect data is updated when the effect data needs to be updated.

  In step SC11, when pressing of the chance button is detected, processing for changing the effect data updated in step SC09 to effect data corresponding to the pressing of the chance button is performed. In step SC13, if there is a command to VDP 434 in the effect data read in SC09, this command is output to VDP 434 (details will be described later). In step SC15, when there is a command to the sound source IC 416 in the effect data read in SC09, this command is output to the sound source IC 416.

  In step SC <b> 17, if there is a command to various lamps 418 in the effect data read in SC <b> 09, this command is output to the drive circuit 420. In step SC19, when there is a command to the shielding device 246 in the effect data read in SC09, this command is output to the drive circuit 432. In step SC21, if there is a control command to be transmitted to the second sub-control unit 500 in the effect data read in SC09, the control command is set to be output, and the process returns to SC03.

  Next, the command reception interrupt process of the first sub-control unit 400 will be described using FIG. This command reception interrupt process is a process executed when the first sub-control unit 400 detects a strobe signal output from the main control unit 300. In step SD01 of the command reception interrupt process, the command output from the main control unit 300 is stored as an unprocessed command in a command storage area provided in the RAM 408.

  Next, the first sub control unit timer interrupt process executed by the CPU 404 of the first sub control unit 400 will be described with reference to FIG. The first sub-control unit 400 includes a hardware timer that generates a timer interrupt at a predetermined cycle (in this embodiment, once every 2 ms), and the timer interrupt process is performed by using the timer interrupt as a trigger. Execute in the cycle.

  In step SE01 of the first sub control unit timer interrupt process, 1 is added to the value of the timer variable storage area of the RAM 408 described in step SC03 in the first sub control unit main process shown in FIG. Is stored in the timer variable storage area. Therefore, in step SC03, the value of the timer variable is determined to be 10 or more every 20 ms (2 ms × 10).

  In step SE03 of the first sub control unit timer interrupt process, a control command is transmitted to the second sub control unit 500 set in step SC19, an effect random number value is updated, and the like.

  Next, the image control process in step SC13 in the main process of the first sub-control unit 400 will be described with reference to FIG. FIG. 5 is a flowchart showing the flow of image control processing.

  In step SF01, an instruction to transfer image data is issued. Here, the CPU 404 first swaps the designation of the display areas A and B in the VRAM 436. As a result, an image of one frame stored in the display area not designated as the drawing area is displayed on the decorative design display device 208. Next, the CPU 404 sets ROM coordinates (transfer source address of the ROM 406), VRAM coordinates (transfer destination address of the VRAM 436) and the like in the attribute register of the VDP 434 based on the position information table and the like, and then the image from the ROM 406 to the VRAM 436. Set an instruction to start data transfer. The VDP 434 transfers the image data from the ROM 406 to the VRAM 436 based on the command set in the attribute register. Thereafter, the VDP 436 outputs a transfer end interrupt signal to the CPU 404.

  In step SF03, it is determined whether or not a transfer end interrupt signal from the VDP 434 is input. If a transfer end interrupt signal is input, the process proceeds to step SF05. Otherwise, a transfer end interrupt signal is input. Wait for it. In step SF05, parameters are set based on the production scenario configuration table and attribute data. Here, in order to form a display image in the display area A or B of the VRAM 436 based on the image data transferred to the VRAM 436 in step SF01, the CPU 404 has information on the image data constituting the display image (coordinate axes and image sizes of the VRAM 436). , VRAM coordinates (arrangement coordinates, etc.) are instructed to the VDP 434. The VDP 434 sets parameters according to attributes based on instructions stored in the attribute register.

  In step SF07, a drawing instruction is performed. In this drawing instruction, the CPU 404 instructs the VDP 434 to start drawing an image. The VDP 434 starts drawing an image in the frame buffer in accordance with an instruction from the CPU 404.

  In step SF09, it is determined whether or not a generation end interrupt signal from the VDP 434 based on the image drawing end is input. If the generation end interrupt signal is input, the process proceeds to step SF11. If not, the generation end interrupt signal is determined. Wait for input. In step SF11, a scene display counter which is set in a predetermined area of the RAM 408 and counts how many scene images have been generated is incremented (+1), and the process ends.

<Processing of Second Sub-Control Unit 500>
The process of the second sub control unit 500 will be described with reference to FIG. FIG. 6A is a flowchart of main processing executed by the CPU 504 of the second sub-control unit 500. FIG. 7B is a flowchart of command reception interrupt processing of the second sub control unit 500. FIG. 8C is a flowchart of the timer interrupt process of the second sub control unit 500.

  First, in step SG01 of FIG. When power is turned on, an initialization process is first executed in SG01. In this initialization processing, initial setting of input / output ports, initialization processing of a storage area in the RAM 508, and the like are performed.

  In step SG03, it is determined whether or not the timer variable is 10 or more. This process is repeated until the timer variable becomes 10, and when the timer variable becomes 10 or more, the process proceeds to step SG05.

  In step SG05, 0 is assigned to the timer variable. In step SG07, command processing is performed. The CPU 504 of the second sub control unit 500 determines whether a command has been received from the CPU 404 of the first sub control unit 400. In step SG09, an effect control process is performed. For example, when there is a new command in SG07, the effect data corresponding to this command is read from the ROM 506, and when the effect data needs to be updated, the effect data is updated.

  In step SG 11, if there is a command from the first sub-control unit 400 to the game board lamp 532 or the game table frame lamp 542, this command is output to the serial communication control circuit 520. In step SG13, if there is a command from the first sub-control unit 400 to the effect movable body 224, this command is output to the drive circuit 516, and the process returns to SG03.

  Next, the command reception interrupt process of the second sub control unit 500 will be described with reference to FIG. This command reception interrupt process is a process executed when the second sub control unit 500 detects the strobe signal output from the first sub control unit 400. In step SH01 of the command reception interrupt process, the command output from the first sub-control unit 400 is stored as an unprocessed command in a command storage area provided in the RAM 508.

  Next, the second sub control unit timer interrupt process executed by the CPU 504 of the second sub control unit 500 will be described with reference to FIG. The second sub-control unit 500 includes a hardware timer that generates a timer interrupt at a predetermined cycle (in this embodiment, once every 2 ms), and the timer interrupt process is predetermined by using the timer interrupt as a trigger. Execute in the cycle.

  In step SI01 of the second sub control unit timer interrupt process, 1 is added to the value of the timer variable storage area of the RAM 508 described in step SG03 in the second sub control unit main process shown in FIG. Is stored in the timer variable storage area. Therefore, in step SG03, the value of the timer variable is determined to be 10 or more every 20 ms (2 ms × 10). In step SI03 of the second sub-control unit timer interrupt process, an effect random number update process is performed.

<Circuit board>
Next, a game board circuit board constituting the pachinko machine 100 will be described. FIG. 10 shows the surface of the circuit board 1 according to an embodiment of the present invention, and shows the layout of components to be mounted. In FIG. 10, illustration of through holes and the like is omitted. FIG. 11 is a view showing the back surface of the circuit board 1. The circuit board 1 is, for example, a circuit board 1 that constitutes a control unit, and is, for example, a circuit board on which an electronic component that controls a game is mounted to constitute the main board 156. 10 and 11 show a state before the electronic component is mounted.

  The circuit board 1 is a printed wiring board including a base substrate made of an insulating material, a wiring pattern formed on the base substrate, and a protective film (for example, a solder resist film) that covers the wiring pattern except for a solder portion. A wiring pattern is comprised from the conductor formed with metal foil, such as copper.

  As shown in FIG. 10, various components are mounted on the surface of the circuit board 1. The components to be mounted include a connector (not shown) mounted on the terminal portion 1a for inputting a signal from a device external to the circuit board 1.

  Referring to FIG. 11, the wiring pattern includes a ground pattern 10 and a plurality of signal lines 20. The ground pattern 10 is a GND pattern of an electric circuit, and the signal line 20 connects terminals of electronic components, for example. A configuration example of the ground pattern 10 and the signal line 20 will be described with reference to FIG. FIG. 12A is an enlarged view of the wiring pattern in the region A of FIG. 11, and shows a configuration example of the signal line 20 connected to the terminal portion of the connector mounting portion 1a and the ground pattern 10.

  In the region A, the ground pattern 10 has a contour line (edge line) combined with a straight line, and the belt-like portion of each signal line 20 is arranged in parallel with the contour line of the ground pattern 10. . The width of the strip portion of the signal line 20 is, for example, 0.3 mm.

  The wiring pattern in region A includes a portion R1 and a portion R2 that are adjacent to each other. In the portion R1, the distance (shortest distance) between the ground pattern 10 and the signal line 20 adjacent to the ground pattern 10 is W1, and the belt-like portion of the signal line 20 extends in parallel with the contour line of the ground pattern 10. Yes. The distance W1 is, for example, 1.5 mm.

  In the portion R2, a convex-shaped portion 21 protruding to the ground pattern 10 is formed on the signal line 20, and the distance (shortest distance) between the ground pattern 10 and the signal line 20 adjacent thereto is W3. Yes. The distance W3 is a distance shorter than the distance W1. The distance W3 is preferably narrower than the width of the belt-like portion of the signal line 20, and is preferably narrower than the interval W4 between the signal lines 20. The interval W4 is, for example, about 1 mm to 1.5 mm.

  As described above, in this embodiment, the portion R1 having the distance W1 between the ground pattern 10 and the adjacent signal line 20 and the portion R2 having W3 shorter than W1 are provided. In some cases, it may be easy to visually recognize the boundary with 10. As a result, for example, the signal line 20 may be easily identified when the signal line 20 is inspected for disconnection. Further, when inspecting whether or not the circuit board 1 is replaced with an unauthorized board, it may be easy to inspect.

  In the portion R2, the portion 21 and the ground pattern 10 may be close to each other so that static electricity on the signal line 20 can be secondary discharged to the ground pattern 10. Thereby, noise on the signal line 20 may be removed, and damage to the electronic component to which the signal line 20 is connected may be prevented. In general, a capacitor or the like is provided for removing noise from the signal line. This causes an increase in the number of components. In the case of this embodiment, noise can be removed by the pattern shape of the signal line 20. In terms of facilitating secondary discharge of static electricity to the ground pattern 10, good discharge is possible if the distance W3 is, for example, 0.2 mm or less, preferably about 0.1 mm (the manufacturing limit of the signal line width is 0. 0). About 08 mm). In addition, if the distance W3 is configured to be the smallest of all the insulating layers formed on the substrate, there is a case where no discharge occurs through the insulating layer in a portion other than the portion R2. is there.

<Configuration example of part R2>
Hereinafter, a configuration example of the portion R2 will be exemplified. Each configuration example including the configuration example of the portion R2 illustrated in FIG. 12A can be combined with each other as appropriate.

  In the example of FIG. 12A, the portion 21 has a triangular shape, but may have another shape. FIG. 12 (b) shows another example of the shape of the portion 21, and in the example of FIG. In other words, the width of the signal line 20 is made wider than other portions.

  In the example of FIG. 12A, the portion 21 is formed on the signal line 20, but may be formed on the ground pattern 10. In FIG. 13A, a portion 11 instead of the portion 21 is formed in the ground pattern 10. The portion 11 has a convex shape protruding to the signal line 20 and is a triangle in the example of the figure, but may be another shape.

  Although the portion 21 is formed on the signal line 20 in the example of FIG. 12A and the portion 11 is formed on the ground pattern 10 in the example of FIG. 13A, both of them may be provided. FIG. 13B shows an example. In the example of the figure, the part 21 of the signal line 20 and the part 11 of the ground pattern 10 are formed at positions facing each other, and the shortest distance W5 is the distance between the vertices. If the shortest distance W5 is at least shorter than the distance W1, the above-described secondary discharge effect may be obtained even if the portion 21 and the portion 11 are formed at positions shifted from each other.

  The portion R2 may be configured to form a portion close to the ground pattern 10 by its contour shape while the width of the signal line 20 is constant. FIGS. 14A and 14B show an example. In the example of FIG. 14A, the signal line 20 is not parallel to the contour line of the ground pattern 10 in the portion R <b> 2, but is obliquely bent so as to extend in the intersecting direction, thereby forming a portion close to the ground pattern 10. doing. Further, in the example of FIG. 14B, the signal line 20 is bent at a right angle to form a portion close to the ground pattern 10. In the example of FIG. 14B, a plurality of portions R2 are formed.

  In view of improving the secondary discharge effect, the portion R2 may be configured not to cover a protective film such as a solder resist film. FIGS. 15A and 15B show an example.

  In the example of FIG. 15A, two portions R <b> 2 are formed, and convex-shaped portions 21 a and 21 that protrude to the ground pattern 10 are formed. The portion 21a is not covered with a protective film, and the conductor constituting the signal line 20 is exposed. Thereby, the secondary discharge effect may be able to be enhanced. In addition, the structure which does not coat | cover a protective film about at least one part instead of the whole part 21a is good. The other portion 21 is covered with a protective film, but the conductor may be exposed without being covered.

  In the example of FIG. 15B, the ground pattern 10 is provided with a portion 12 that does not cover a protective film such as a solder resist film. In the example of the figure, the portion 12 is a portion corresponding to the portion 21 a of the signal line 20. Thereby, the secondary discharge effect may be further improved. Needless to say, the portion not covering the protective film may be formed only on the ground pattern 10 side.

  In each of the above examples, the signal line 20 adjacent to the ground pattern 10 is targeted, but other signal lines may also be targeted. FIG. 16A shows an example. In the example shown in the figure, a protruding portion 21 protruding to the ground pattern 10 is formed on the signal line 20A adjacent to the ground pattern 10 and the signal line 20B adjacent to the signal line 20A. Two portions 21 are formed on the signal line 20A, and one portion 21 is formed on the signal line 20B. Needless to say, the number of the portions 21 may be other than this.

  With this configuration, the boundary between the signal line 20A and the ground pattern 10 may be easily visible. In addition, since the portion 21 is formed on the signal line 20B, static electricity on the signal line 20B may be secondary discharged to the signal line 20A and further to the ground pattern 10 in some cases. When the portion 21 of the signal line 20B and one portion 21 of the signal line 20A are arranged side by side toward the ground pattern 10 as shown in FIG. 16A, this secondary discharge effect is further improved. There are cases where you can

  Next, at least one of the signal line 20 and the ground pattern 10 is formed with a recessed portion, and the other of the signal line 20 and the ground pattern 10 has at least a portion that enters the recessed portion. It may be formed. FIG. 16B shows an example.

  In the example shown in the figure, a recessed portion 13 is formed in the ground pattern 10. In the signal line 20, a portion 24 that partially enters the portion 13 is formed. The portion 24 forms a land around the through hole. In this way, the portion R2 can also be configured in combination with the concave-shaped portion 13 by using the portion 24 to be originally formed in the wiring pattern.

  Next, a signal line in which the portion R2 is preferably provided will be described. Noise such as static electricity tends to enter a signal line through which a signal from a device external to the circuit board 1 is input. In the present embodiment, the portion R2 is provided for the signal line 20 connected to the terminal portion 1a to which the connector is attached, but this may be advantageous in terms of noise removal.

  Noise such as static electricity is likely to occur due to collision of members. At this point, a sensor that detects the entry of a ball to the ball entrance (for example, the general prize opening 226, the general figure starting port 228, the first special figure starting port 230, the second special figure starting port 232, the variable winning port 234). The signal from is easy to get noise. Therefore, for example, as shown in FIG. 17A, it may be advantageous in terms of noise removal due to secondary discharge if the portion R2 is provided on the signal line to which the signal of the ball detection sensor is input on the main board 156. is there.

  In addition, noise such as static electricity is likely to come in from the part touched by humans. In this regard, noise is likely to be applied to signals from sensors around the ball launch handle 134. Therefore, for example, as shown in FIG. 17B, if a portion R2 is provided on the signal line to which the touch sensor and the firing stop switch signal are input on the launch board 174, it is advantageous in terms of noise removal by secondary discharge. There is a case. The touch sensor is a sensor that detects whether or not the player is touching the ball launch handle 136, and the launch stop switch is a switch that allows the player to instruct the stop of the launch of the ball.

  Further, the signal lines around the sensor as described above are arranged at the position of the signal line 20a closest to the ground pattern 10 in FIG. 16B, and the other signal lines are arranged at the position of 20b. The noise of the signal line 20a that is most likely to generate noise is not discharged to other signal lines, and the ground pattern 10 may be more advantageous in terms of noise removal by secondary discharge.

<Identification sign>
Next, the identification mark displayed on the circuit board 1 will be described. As shown in FIG. 11, in this embodiment, an identification mark region B where an identification mark is displayed on the back surface of the circuit board 1 is formed. The identification marker region B is partitioned by a conductor that forms a wiring pattern. In the case of the present embodiment, the identification mark region B is formed in a rectangular shape by removing a part of the conductor in the region where the ground pattern 10 is formed. Note that the shape of the identification marker region B may be other than a square.

  FIG. 18A is an enlarged view around the identification mark area B, and is an explanatory view of the identification mark. The identification mark SY shown in the figure is composed of a total of five identifiers of four identifiers C1 and one identifier C2. Note that the number of identifiers constituting the identification mark SY is not limited to five, and may be plural. The identifier may be any character, number, symbol, or the like.

  In the present embodiment, the identification sign area B includes a common identifier display area D1 in which the identifier C1 is displayed and an additional identifier display area D2 in which the identifier C2 is displayed. Since these are included in one identification mark area B, the identification mark SY may be easily read as one piece of information.

  In the common identifier display area D1, for example, an identifier common to the plurality of circuit boards 1 can be displayed. In the present embodiment, the four identifiers C1 constitute a common identifier for the plurality of circuit boards 1. For example, when a common circuit board 1 is used in a plurality or a plurality of types of game machines, the management may be facilitated. Note that the number of common identifiers is not necessarily four, but may be one or more.

  In the additional identifier display area D2, for example, an identifier added to the common identifier can be displayed. In this embodiment, the identifier C2 constitutes an identifier added to the common identifier C1. For example, when a common circuit board 1 is used in a plurality of types of game machines, the correspondence between the type of game machine and the circuit board 1 may be easily managed. In addition, as an electronic component to be mounted on the circuit board 1, when using an improved IC with the same pin arrangement but improved performance from the previously used IC, a general-purpose IC socket is mounted. In some cases, the management of the correspondence between the electronic component to be mounted and the circuit board 1 may be facilitated, as in the case where an IC, ROM, or the like that matches the performance required for each game machine is mounted on the IC socket. is there. Note that the number of additional identifiers is not necessarily one, and may be two or more.

  The identifier C1 displayed in the common identifier display area D1 is provided at the manufacturing stage of the circuit board 1, while the identifier C2 displayed in the additional identifier display area D2 can be provided thereafter. FIG. 18B shows the configuration of the identification mark region B of the circuit board 1 at the manufacturing stage. Although the identifier C1 is displayed in the common identifier display area D1, the additional identifier display area D2 is blank. Thereby, while the circuit board 1 is made common, it may be possible to set an identification mark SY according to application to a game machine developed after the manufacture or according to a change of electronic components.

  In the present embodiment, a height difference is generated between the identifier C1 and the identifier C2. FIG. 19A is a perspective view of a part of identifier C1 and identifier C2. As shown in the figure, the identifier C1 is convex, and the identifier C2 is concave. Thereby, the distinction between the identifiers C1 and C2 in the identification mark SY may be easily made visually. In addition, since the identifiers C1 and C2 have a three-dimensional shape, it may be difficult to perform fraud.

  FIG. 19B is a cross-sectional view taken along line II. As already outlined, the circuit board 1 is a laminated body of the base substrate 2, the conductor 3 of the wiring pattern, and the protective film 4 (for example, a solder resist film) that covers the conductor 3. In the case of the present embodiment, the identifier C1 is formed by leaving the conductor 3 at the time of etching, and its surface is located at a position H1 higher than the reference position H0 when the back side surface of the base substrate 2 is the reference position H0. The distance of the height difference is + h1. On the other hand, the identifier C2 is formed by, for example, engraving the back side surface of the circuit board 1 (particularly the base substrate 2) by laser processing or machining, and the surface is located at a position H2 lower than the reference position H0. The height difference distance is -h2. Note that h1 and h2 may be the same or different.

  Thus, in this embodiment, the height difference is provided between the identifier C1 and the identifier C2. The identifier C1 is made of the conductor 3 and is firmly fixed to the base substrate 2. Therefore, it is difficult to erase the identifier C1 without a trace by fraud. Further, since the identifier C2 is also engraved on the base substrate 2, it is difficult to erase the identifier C2 without a trace by fraud.

  In this embodiment, the identifier C1 is protruded and the identifier C2 is recessed. Conversely, the identifier C2 may be protruded and the identifier C1 may be recessed. The formation method of the identifiers C1 and C2 is not limited to the conductor remaining and the engraving of the base substrate 2, and any method may be used as long as a difference in height can be given. In addition, the identifier C1 and the identifier C2 do not need to have a concave-convex relationship with respect to the reference position H0. The height may be changed to have a convex-convex relationship, or the depth may be changed to have a concave-convex relationship. . Furthermore, the identifier C1 and the identifier C2 which are continuously located may be sufficient as the identifier which changes a height difference. For example, although there are four identifiers C1 in this embodiment, only the identifier C1 of “F” may cause a difference in height from the identifier C2. When there are a plurality of identifiers C2, only the identifier C2 adjacent to the identifier C1 of “F” may cause a height difference from the identifier C1. Further, the reference position H0 may be a part other than the surface of the base substrate 2, such as a solder resist film surface or a conductor surface.

  In the present embodiment, four identifiers C1 are displayed in a row in the common identifier display region D1, and the additional identifier display region D2 is formed on the rear side (right side) in the column direction. For example, FIG. As shown, the additional identifier display area D2 may be formed on the front side (left side), or the additional identifier display area D2 may be formed on both the front side and the rear side. Thereby, the position of the additional identifier display area D2 with respect to the common identifier display area D1 may be easily understood, and as a result, the distinction between the identifiers C1 and C2 in the identification mark SY may be easily visualized. The identification mark SY is not limited to horizontal writing but may be vertical writing as shown in FIG.

  In this embodiment, the common identifier display area D1 and the additional identifier display area D2 are included in one identification marker area B. For example, as shown in FIG. It may be divided into an identification mark area B1 for use and an identification sign area B2 for the additional identifier display area D2. The position of the additional identifier display area D2 may be easily understood.

  Moreover, the structure which does not partition at least one part of the label | marker area | region B with the conductor 3 is also employable. FIG. 21B shows an example. In the example shown in the figure, a common identifier display area D1 is set in the ground pattern 10, and an identifier C1 is formed. In the case of this configuration, the identifier C1 can be formed by, for example, a recess. The additional identifier display area D2 is partitioned by the conductor 3, and the identifier C2 can be formed by, for example, a recess deeper than the identifier C1. Thus, by dividing only the display area of the additional identifier, the position of the additional identifier display area D2 may be easily understood.

  One of the identifiers may be formed by silk printing or a seal.

<Embodiment 2>
In addition to the pachinko machine 100 of the first embodiment, the present invention can be applied to various game machines such as a slot machine. As an example, as shown in FIG. 22, “a plurality of reels 1002 provided with a plurality of types of symbols and driven to rotate, a start lever 1004 for instructing rotation of the reels, and a reel provided corresponding to each reel. A stop button 1006 for individually stopping the rotation, lottery means (winning part internal lottery) for determining whether or not an internal winning of a plurality of types of winnings is made by lottery, and reel rotation based on the lottery result of the lottery means The symbol combination displayed by the reel stop control means (reel stop control processing) for performing stop control related to the stop and the reels stopped based on the lottery result of the lottery means is determined in advance according to the winning combination.
