<Discharge control unit, launch control unit, power supply management unit>
Next, the payout control unit 600, the launch control unit 630, and the power management 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 signal such as a command transmitted from the main control unit 300, and based on a control signal output from the payout sensor (game ball detection sensor) 604. In addition, it is detected whether or not the payout of the winning ball or the rented ball has been completed, and communication with a card unit 608 provided separately from the pachinko machine 100 is performed via the interface unit 606.

  The launch control unit 630 outputs a control signal output from the payout control unit 600 to permit or stop the launch, or a launch intensity output circuit provided in the ball launch handle 134 to operate the ball launch handle 134 by the player.

  The power management unit 660 converts the AC power supplied from the outside to the pachinko machine 100 into a DC voltage, converts it into a predetermined voltage, and controls each control unit such as the main control unit 300 and the first sub control unit 400, the payout device 152, etc. Supply to each device. Further, the power management unit 660 supplies a power storage circuit (for example, a power supply circuit) for supplying power to a predetermined part (for example, the RAM 308 of the main control unit 300) for a predetermined period (for example, 10 days) even after the external power supply is cut off. , Capacitor). In the present embodiment, a predetermined voltage is supplied from the power management unit 660 to the payout control unit 600 and the second sub control unit 500, and the main control unit 300, the second sub control unit 500, and the launch control unit are supplied from the payout control unit 600. Although a predetermined voltage is supplied to 630, the predetermined voltage may be supplied to each control unit and each device through another power supply path.

<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 (game ball detection sensor) detects that the ball has entered the first special figure start port 230. The special figure 2 variable game is started on condition that the second start port sensor (game ball detection sensor) detects that the ball has entered. 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 the figure, the white portions in the figure 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”. A first start port sensor (game ball detection sensor) that a ball has won the first special figure start port 230 or the second special view start port 232, that is, that the ball has entered the first special view start port 230. On the left of the decorative symbol display device 208 on the condition that the second start port sensor (game ball detection sensor) has detected that the ball has entered the second special figure start port 232 In each of the symbol display areas of the area 208a, the middle symbol display area 208b, and the right symbol display area 208c, “decoration 1” → “decoration 2” → “decoration 3” →... “Decoration 9” → “decoration 10” → “Decoration pattern change display” is performed to switch the display in the order of “decoration 1” →. 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 the 15R special jackpot of “special drawing A” is notified, 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 (game ball detection sensor) has detected that the ball has passed through the general-purpose starting port 228, the normal symbol display device 210 has the seven segments fully lit and the central one. Repeatedly turn on the segment of “Usual 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 the figure, the white portions in the figure 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, stack initial value setting (temporary setting) to the stack pointer (SP) of the CPU 304, interrupt mask setting, I / O 310 initial setting, initial setting of various variables stored in the RAM 308, and WDT 313 The operation is permitted and initial values are set. In the present embodiment, a numerical value corresponding to 32.8 ms is set in WDT 313 as an initial value.

  In step SA03, the counter value of WDT 313 is cleared, and the time measurement by WDT 313 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 management 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 resumed from the instruction next to the instruction (predetermined in step SA15 and step SA17) performed immediately before branching to the timer interrupt process (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 number value are updated. For example, if the range of values that can be taken as normal timer random numbers is 0 to 20, 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 21, 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. Further, after this basic random number initial value update process is completed, an interrupt permission is set, and the process proceeds to Step SA17.

  In step SA17, 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 the RAM 308 of the main control unit 300, a first special figure notice lottery random number counter for generating a first special figure notice lottery random number value that can take a value in the range of 0 to 127, and a value in the range of 0 to 127 are also taken. A second special figure notice lottery random number counter for generating a second special figure notice lottery random number value to be obtained is provided. In step SA17, the values of these counters are updated.

  The main control unit 300 repeatedly executes the processes of step SA15 and step SA17 except during the 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 WDT interrupt does not occur (so as not to detect a processing abnormality) so that the count value of the WDT 313 exceeds the initial set value (32.8 ms in this embodiment). 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 various sensors 320 including the above-mentioned front frame door open sensor, inner frame open sensor, lower plate full sensor, and various game ball detection sensors are connected via the input port of the I / O 310. The detection signal is input to monitor the presence / absence of the detection signal, and stored in a signal state storage area provided for each sensor 320 in the RAM 308. If the detection signal of the game ball detection sensor is described as an example, information on the presence / absence of the detection signal of each game ball detection sensor detected in the timer interruption process (about 4 ms before) is stored in the RAM 308 in each game ball. Read from the previous detection signal storage area provided for each detection sensor, store this information in the RAM 308 in the previous detection signal storage area provided for each game ball detection sensor, and perform the previous timer interrupt processing. Information about the presence / absence of the detection signal of each game ball detection sensor detected about (before 2 ms) is read from the current detection signal storage area provided for each game ball detection sensor in the RAM 308, and this information is described above. Is stored in the previous detection signal storage area. Further, the detection signals of the respective game ball detection sensors detected this time are stored in the above-described current detection signal storage area.

  Further, in step SB05, the information on the presence / absence of the detection signal of each game ball detection sensor stored in each of the storage areas 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 each game ball detection sensor matches the winning determination pattern information. This main control unit timer interruption process that is repeatedly started at a very short interval of about 2 ms is started several times while one game ball passes through one game ball detection sensor. 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 game ball detection sensor is confirmed. As a result, a detection signal indicating that the same game ball has passed through the same game 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. In other words, when the game ball starts to pass through the game ball detection sensor, there is no detection signal before, there is a previous detection signal, and there is a detection signal this time. In the present embodiment, in consideration of erroneous detection and noise of the game ball detection sensor, it is determined that there is a prize when the detection signal is stored twice consecutively 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, the information on the presence or absence of detection signals for the past three times in each game ball detection sensor is pre-determined winning determination pattern information (in this embodiment, no previous detection signal, previous detection signal, current detection signal). In the case of a match with the general prize opening 226, the variable prize opening 234, the first special figure start opening 230, and the second special figure start opening 232, or the general figure start opening It is determined that 228 has passed. In other words, it is determined that there has been a winning at these winning ports 234, 230 and the starting ports 230, 232, 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 (game ball detecting sensor) for detecting the winning at the general winning opening 226, the general winning is shown. When it is determined that there is a winning at the mouth 226, and processing associated with the subsequent winning at the general winning mouth 226 is performed, the information on the presence / absence of detection signals for the past three times does not match the above-described winning determination pattern information. Branches to the subsequent process without performing the process associated with winning a prize to the general winning opening 226 thereafter. 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 determining 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 game ball detection sensor. If it matches the clear 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 a round as a result of adding 1 to the acquired value, the value of the initial value generation 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. Here, the random number counter for generating the effect random number performed in step SA17 is updated. Accordingly, the values of the special figure 1 notice lottery random number counter and the special figure 2 notice lottery random number counter are updated in this step SB11.

  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 update process, when winning holes 234, 230 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 step SB19, a payout request number transmission process is performed. The output schedule information and the payout request information output to the payout control unit 600 are composed of 1 byte, strobe information in bit 7 (indicating that data is set when on), and power supply in bit 6. Input information (indicating that it is the first command transmission after power-on when turned on), bits 4-5 for the current processing type for encryption (0-3), and bits 0-3 for encryption processing The number of subsequent payout requests is indicated.

  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 is held open by the solenoid (332) for opening and closing the blade member of the second special figure starting 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.

  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 number value, and a plurality of fluctuation times are obtained based on the acquired general figure timer random number value. One time for displaying the variable map on the general map display device 112 is selected from among them, and this variable display time is stored in the general map variable time storage area provided in the RAM 308 as the normal map variable display time. 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).

  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 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 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).

  In addition, in order to execute the general command rotation stop setting transmission process in the command setting transmission process (step SB33), 4H is additionally stored as transmission information (general information) in the transmission information storage area described above, and the variable display is stopped. The special figure 2 identification information indicating that is special figure 2 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, 5H is additionally stored as transmission information (command type) in the above-described transmission information storage area in order to execute the general command winning effect setting transmission process in the command setting transmission process (step SB33).

  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) Or, until a winning of a predetermined number of game balls (for example, 10 balls) is detected in the variable winning opening 234.) The door member is opened to the open / close driving solenoid (332) of the variable winning opening 234. A signal to be held is output, and information indicating an opening period is set in a storage area of a door opening time management timer provided in the RAM 308. Further, 7H is additionally stored as transmission information (command type) in the above-described transmission information storage area in order to execute the general command big prize opening release setting transmission process in the command setting transmission process (step SB33).

  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 in a closed state is output to the solenoid (332) for opening and closing the door member 1301 of the variable prize opening 234, and a closing period is set in the storage area of the door closing time management timer provided in the RAM 308. Set the information to show. Further, 8H is additionally stored as transmission information (command type) in the above-described transmission information storage area in order to execute the general command big prize opening closing setting transmission process in the command setting transmission process (step SB33).

  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 ordinary probability fluctuation flag is set to OFF, the number of time reductions 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. In the ordinary high probability state, compared to the ordinary low probability state, if the common figure variable game is hit, there is a high possibility that the variation time will be shortened. Also, the fluctuation time of the normal figure variable game is 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 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 are more likely to be opened 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 starting port 232 during the jackpot game until a predetermined number of game balls are entered in the variable winning slot 234. 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.

  Furthermore, 6H is additionally stored as transmission information (command type) in the above-described transmission information storage area in order to execute the general command end effect setting transmission process in the command setting transmission process (step SB33).

  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. Note that the output schedule information transmitted to the first sub-control unit 400 is composed of 16 bits in the present embodiment, bit 15 is strobe information (indicating that data is set when ON), bit 11 -14 are command types (in this embodiment, commands 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, FRAM clear command, etc. Information that can specify the type), 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 general command rotation start setting transmission process described above, the value of the 15R jackpot flag or 2R jackpot flag, the value of the special figure probability fluctuation flag, the special figure related lottery process, and the special figure stored in the RAM 308 as command data 2. Information indicating the timer number selected in the related lottery process, the number of the first special figure variable game or the second special figure variable game held, etc. is set. In the general command 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 above-mentioned general command winning effect setting transmission process, the command data stored in the RAM 308, the effect control information output to the decorative symbol display device 208, various lamps 423, and the speaker 120 during the winning effect period, the special figure probability variation Information indicating the value of the flag, the number of the first special figure variable game or the second special figure variable game held, etc. is set. In the above-described general command end effect setting transmission process, command control data stored in the RAM 308, effect control information output to the decorative symbol display device 208, the various lamps 418, and the speaker 120 during the effect standby period, special figure probability variation Information indicating the value of the flag, the number of the first special figure variable game or the second special figure variable game held, etc. is set. In the general command big prize opening release transmission process described above, the number of big hits stored in the RAM 308 in the command data, the value of the special figure probability fluctuation flag, the first special figure fluctuation game or the second special figure fluctuation held. Information indicating the number of games is set. In the above-mentioned general command big prize opening closing setting transmission process, the number of big hit rounds stored in the RAM 308 in the command data, the value of the special figure probability fluctuation flag, the first special figure fluctuation game or the second special figure fluctuation held Information indicating the number of games is set. 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 334.

  In step SB37, device monitoring processing is performed. Details of the device monitoring process will be described later.

  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.

<Device monitoring processing>
Next, the device monitoring process in step SB37 in the main control unit timer interrupt process will be described with reference to FIG. This figure is a flowchart showing the flow of device monitoring processing.

  In step SC01, it is determined whether or not the detection signal from the abnormality detection sensor is off. Although details will be described later, in this embodiment, the abnormality detection sensor outputs ON as a detection signal unless an abnormality (occurrence of an illegal induction magnetic field) is detected, and outputs OFF as a detection signal when an abnormality is detected. It is configured as follows. When the detection signal from the abnormality detection sensor is off (when abnormality is detected), the process proceeds to step SC03, and when the detection signal is on (when abnormality is not detected), the process proceeds to step SC05.

  In step SC03, abnormality occurrence information (information indicating the occurrence of an induction magnetic field or failure of the abnormality detection sensor) is stored in the external output signal setting area provided in the RAM 308. The abnormality occurrence information stored here is output to the information input circuit 350 provided in an external hall computer or the like in the external output signal setting process (step SB35) of the main control unit timer interrupt process.

  In step SC05, other processing is performed. Here, the signal statuses of various sensors stored in the signal status storage area in the input port status update processing (step SB05) of the main control unit timer interrupt processing are read out, whether there is a front frame door open error or a lower pan full error 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 the presence of the front frame door opening error or the lower pan full error. Set device information that indicates presence or absence. 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).

<Processing of First Sub-Control Unit 400>
Next, processing 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 command reception interrupt processing 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.

  First, in step SD01 in FIG. 9A, various initial settings are performed. When the power is turned on, an initialization process is first executed in SD01. In this initialization process, initialization of input / output ports, initialization of a storage area in the RAM, and the like are performed.

  In step SD03, 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 SD05.

  In step SD05, 0 is assigned to the timer variable. In step SD07, 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 SD09, effect control processing is performed. For example, when there is a new command in step SD07, processing such as reading effect data corresponding to the command from the ROM 406 is performed, and when update of the effect data is necessary, effect data update processing is performed.

  In step SD11, when pressing of the chance button is detected, processing for changing the effect data updated in step SD09 to effect data corresponding to the pressing of the chance button is performed. In step SD13, if there is a command to the sound source IC 416 in the effect data read in step SD09, this command is output to the sound source IC 416. In step SD15, if there is a command to various lamps 418 in the effect data read in step SD09, this command is output to the drive circuit 420.

  In step SD17, when there is a command to the effect movable body 224 in the effect data read in step SD09, this command is output to the drive circuit 422. In step SD19, if there is a control command to be transmitted to the second sub-control unit 500 in the effect data read in step SD09, the control command is set to be output, and the process returns to step SD03.

  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 SE01 of the command reception interrupt process, the command output from the main control unit 300 is stored in the command storage area provided in the RAM 408 as an unprocessed command.

  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). Execute in the cycle.

  In step SF01 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 SD03 in the first sub-control unit main process shown in FIG. Is stored in the timer variable storage area. Therefore, in step SD03, the value of the timer variable is determined to be 10 or more every 20 ms (2 ms × 10). In step SF03, transmission of a control command to the second sub-control unit 500 set in step SD19, an effect random number update process, and the like are performed.

<Structure and arrangement of game ball detection sensor and abnormality detection sensor>
Next, the structure and arrangement of the game ball detection sensor and the abnormality detection sensor will be described with reference to FIGS. First, FIG. 10 is an exploded perspective view showing the structure of the game ball detection sensor 700.

As shown in the figure, the game ball detection sensor 700 includes a housing 702, a detection coil 704 disposed in the housing 702, a circuit unit 706, and a connector 708.

  The housing 702 includes a case 702a in which the detection coil 704, the circuit unit 706, and the connector 708 are disposed, and a cover 702b that is fixed to the case 702a by a snap-fit structure. The case 702a and the cover 702b are each made of a material such as resin, and among these, the cover 702b is made of a transparent resin so that the state of the internal circuit portion 706 can be visually recognized. Note that the case 702a may be made of a transparent resin.

  A cylindrical coil spool 702c for winding the detection coil 704 is provided on one end side of the case 702a, and a through hole 710 through which a game ball as a detection body passes is provided inside the coil spool 702c. Is provided. That is, the through hole 710 is a detection region for detecting the detection body. An opening 712 is provided at a position corresponding to the through hole 710 of the cover 702b.

  The detection coil 704 is wound around the coil spool 702c and is electrically connected to the circuit unit 706. A protective cover 714 that covers the detection coil 704 is attached to the outside of the detection coil 704. The circuit unit 706 includes a microcomputer chip and the like, and controls the game ball detection sensor 700. A specific configuration of the circuit unit 706 will be described later. The connector 708 is provided at the end of the circuit unit 706 on the opposite side of the detection coil 704, and wiring for transmitting and receiving signals is connected between the circuit unit 706 and the main control unit 300.

  FIG. 11 is an exploded perspective view showing the structure of the abnormality detection sensor 800. The abnormality detection sensor 800 detects the generation of an illegal induction magnetic field that erroneously operates the game ball detection sensor 700 used as the payout sensor 604 and the game ball detection sensor 700 provided at each winning opening and start port. is there.

The case 802a and the cover 802b are each made of a material such as resin. Case 802a and cover 802b may be made of a transparent material or may be made of an opaque material.

  A cylindrical coil spool 802c for winding the detection coil 804 is provided on one end side of the case 802a, and a part of the case 802a is bulged in the detection region 810 inside the coil spool 802c. A detection body fixing portion 816 formed in a shape is provided. A metal detection body 820 is fixed inside the detection body fixing portion 816. Therefore, the abnormality detection sensor 800 of the present embodiment is always in a state where the detection body 820 is detected in a normal state.

  Note that an opening 812 is provided at a position corresponding to the detection region 810 of the cover 802b, and a window is provided on the surface of the detection body fixing portion 816 that faces the opening 812. Therefore, the cover 802b is fixed to the detection body fixing portion 816. The state of the detected object 820 can be confirmed from the outside.

  The detection coil 804 is wound around the coil spool 802c and is electrically connected to the circuit unit 806.

Thereby, the diversion property of parts is improved, the productivity of the abnormality detection sensor 800 is improved, and the manufacturing cost of the pachinko machine 100 is reduced.

  FIGS. 12A to 12C are schematic diagrams illustrating an example in which an abnormality detection sensor 800 is configured using an existing game ball detection sensor.

  As shown in the external perspective view of FIG. 6A and the cross-sectional view of FIG. 6B, in the existing game ball detection sensor, the detection region 810 that is a through-hole through which the game ball as the detection body passes is provided. The abnormality detection sensor 800 may be configured by fixing the metal detection body 820. The detection body 820 may use a game ball as the detection body 820 as shown in FIG.

  FIG. 13 is a diagram showing the arrangement of the abnormality detection sensor 800. As shown in the figure, the abnormality detection sensor 800 is a game board 200 in the vicinity of the game ball detection sensor 700 and the game ball detection sensor 700 provided as a payout sensor 604 provided at each winning opening and start opening. Is arranged. The anomaly detection sensor 800 is preferably arranged on the side close to the fraudster who generates an illegal induced magnetic field in order to increase detection sensitivity. In this embodiment, the anomaly detection sensor 800 is located in front of the payout sensor 604 and the game ball detection sensor 700. (Front side).

  It should be noted that a plurality of abnormality detection sensors 800 may be arranged in the vicinity of the game ball detection sensor 700 and the payout sensor 604 provided at each winning opening and start opening.

<Circuit configuration and operation principle of game ball detection sensor and abnormality detection sensor>
Next, the circuit configuration and operation principle of the game ball detection sensor 700 and the abnormality detection sensor 800 will be described with reference to FIG. FIG. 4A is a block diagram showing the configuration of the circuit unit 706 of the game ball detection sensor 700, and FIG. 2B is a diagram showing the operating principle of the game ball detection sensor 700 in a normal state. FIG. (C) is a diagram showing the operating principle of the gaming ball detection sensor 700 when it is abnormal. 2B and 2C show the state of the oscillation signal and the output with the horizontal axis as the time axis t.

  As shown in FIG. 5A, the circuit unit 706 of the game ball detection sensor 700 includes an oscillation circuit 706b to which a detection coil 704 and an oscillation capacitor 706a are connected, a detection circuit 706c, a comparator circuit 706d, and an output. The circuit is composed of a circuit 706e and an interface circuit 706f.

  The oscillation circuit 706b is a circuit that generates an oscillation signal that is a continuous alternating current, and generates an alternating magnetic field together with the detection coil 704 and the oscillation capacitor. The detection circuit 706c is a circuit that shapes the waveform of the oscillation signal from the oscillation circuit 706b, detects the amplitude value (voltage) of the oscillation signal, and outputs it to the comparator circuit 706d. The comparator circuit 706d includes a reference voltage generation circuit that generates a reference voltage serving as a threshold, and compares the amplitude value of the oscillation signal detected by the detection circuit 706c with the reference voltage. The output circuit 706e is a circuit that outputs a detection signal indicating that a game ball has been detected to the main control unit 300 via the interface circuit 706f based on the comparison result of the comparator circuit.

  As shown in FIG. 5B, in a state where no game ball is detected, an oscillation signal whose voltage changes with a predetermined amplitude value is output to the detection circuit 706c by the oscillation circuit 706b, and the detection circuit 706c The amplitude value of the signal is detected and output to the comparator circuit 706d. When the game ball enters the detection area (through hole 710) inside the detection coil 704, the impedance changes due to the eddy current generated in the game ball, and the amplitude value of the oscillation signal decreases. Specifically, the amplitude value of the oscillation signal gradually decreases from a predetermined amplitude value to 0 as the game ball enters the detection area, and then becomes the oscillation signal as the game ball escapes from the detection area. When the game ball completely deviates from the detection area, the amplitude value returns to a predetermined amplitude value.

  If the amplitude value output from the detection circuit 706c becomes equal to or lower than the reference voltage (threshold value), the comparator circuit 706d outputs that fact to the output circuit 706e. As long as a signal indicating that the amplitude value is equal to or less than the reference voltage is input from the comparator circuit 706d, the output circuit 706e outputs a detection signal indicating that a game ball has been detected to the main control unit 300 (the detection signal is Will be on). When the amplitude value of the oscillation signal is equal to or higher than the reference voltage, the output circuit 706e does not output the detection signal (the detection signal is turned off).

  As shown in FIG. 6C, when an abnormality occurs, that is, when an improper induced magnetic field is generated, an induced voltage is generated in the oscillation signal by this induced magnetic field. As shown in FIG. The comparator circuit 706d cannot detect a decrease in the amplitude value due to the passage of the game ball because it is in a state as if it oscillates with an amplitude value equal to or higher than the reference voltage. Therefore, it becomes impossible to detect a game ball.

  The circuit unit 806 of the abnormality detection sensor 800 of the present embodiment has the same configuration as the game ball detection sensor 700 circuit unit 706 shown in FIG. Therefore, the operation principle is the same as that of the game ball detection sensor. However, in the abnormality detection sensor, since the detection body 820 is always disposed inside the detection coil 806, the amplitude value of the oscillation signal is always maintained substantially zero by the detection body 820 in the normal state. Accordingly, since the amplitude value is always equal to or lower than the reference voltage, a detection signal is always output to the main control unit 300 during normal operation (the detection signal is kept on).

<Operation at the time of abnormality of the dispensing sensor and abnormality detection sensor>
Next, the operation at the time of abnormality of the game ball detection sensor 700 and the abnormality detection sensor 800 used as the payout sensor 604 will be described with reference to FIG. The figure shows the operation of the payout sensor 604 (game ball detection sensor 700) and the abnormality detection sensor 800 at the time of abnormality, and shows the state of the payout sensor 604 (game ball detection sensor 700) at the top. The state of the abnormality detection sensor 800 is shown at the bottom.

  As described above, when an improper induction magnetic field is generated, an oscillation signal that oscillates with an amplitude value greater than or equal to the reference voltage as shown by a one-dot chain line in the same figure is generated. Therefore, the game ball detection sensor used as the payout sensor 604 In 700, the game ball cannot be detected, and the number of payouts cannot be counted. When the payout sensor 604 becomes incapable of counting in this way, the payout control unit 600 determines that the game ball is not paid out and continues to rotate the sprocket of the payout device 152, so that there are more game balls than the preset number. Will be paid out.

  On the other hand, in the abnormality detection sensor 800, the amplitude value of the oscillation signal that was substantially 0 at normal time becomes an amplitude value that is equal to or greater than the reference voltage due to an incorrect induction magnetic field, and thus the detection signal is turned off. As described above, the abnormality detection sensor 800 of the present embodiment detects the generation of an illegal induction magnetic field by turning off the detection signal that is on in the normal state.

  In the abnormality detection sensor 800 of the present embodiment, the reference voltage value serving as a threshold value for switching on / off the detection signal is set to be smaller than the reference voltage value of the game ball detection sensor 700. In other words, in the present embodiment, by setting the abnormality detection sensor 800 with higher sensitivity than the game ball detection sensor 700, it is possible to surely find a fraudulent act and to discover a preliminary act that is a previous stage of the fraudulent act. Making it possible.

<Operation at the time of abnormality of the game ball detection sensor and the abnormality detection sensor provided at the winning opening>
Next, the operation at the time of abnormality of the game ball detection sensor 700 and the abnormality detection sensor 800 provided at the winning opening and the start opening will be described with reference to FIGS. FIG. 5A is a diagram showing the operation of the game ball detection sensor 700 when winning one ball, and FIG. 5B shows the game ball detection sensor 700 and the abnormality when an abnormality occurs when winning one ball. FIG. 6 is a diagram illustrating an operation of a detection sensor 800. Further, in FIG. 5B, the state of the game ball detection sensor 700 is shown in the upper part, and the state of the abnormality detection sensor 800 is shown in the lower part.

  A game ball that has won (entered) a winning opening or the like passes through a detection area inside the through-hole 710 of the game ball detection sensor 700, that is, inside the detection coil 704. Then, as shown in FIG. 5A, the amplitude value of the oscillation signal decreases from a predetermined amplitude value. The output circuit 706e turns on the detection signal while the amplitude value of the oscillation signal is equal to or lower than the reference voltage.

  As shown in FIG. 6B, when an illegal induction magnetic field is generated twice, for example, intermittently while the game ball is passing through the through-hole 710, the reference voltage exceeds the reference voltage generated thereby. The state where the detection signal is on is divided into three by the oscillation signal of the amplitude value. Then, the main control unit 300 determines that a winning of three game balls has been detected.

  On the other hand, in the abnormality detection sensor 800, an oscillation signal having an amplitude value equal to or higher than the reference voltage is generated by an illegal induction magnetic field, so that the detection signal is intermittently turned off twice. Thereby, such an illegal act can be discovered.

<To identify the occurrence of abnormality and failure of abnormality detection sensor>
Next, the case where the occurrence of abnormality and the failure of the abnormality detection sensor are identified will be described with reference to FIG. This figure is a flowchart showing the flow of device monitoring processing when an occurrence of an abnormality and a failure of an abnormality detection sensor are identified.

  In step SG01, it is determined whether or not the detection signal from the abnormality detection sensor 800 is off. When the detection signal from the abnormality detection sensor 800 is off (when an abnormality is detected), the process proceeds to step SG03, and when the detection signal is on (when no abnormality is detected), the process proceeds to step SG21.

  In step SG03, it is determined whether or not abnormality (inductive magnetic field) occurrence information is stored in the abnormality occurrence history setting area provided in the RAM 308. If the abnormality occurrence information is not stored, the process proceeds to step SG05, and if stored, the process proceeds to step SG11.

  In step SG05, abnormality occurrence information (information indicating the generation of an induced magnetic field) is stored in the external output signal setting area provided in the RAM 308. In step SG07, the abnormality occurrence information is stored in the abnormality occurrence history setting area. In step SG09, the abnormality occurrence timer provided in the RAM 308 is incremented.

  In step SG11, the abnormality occurrence timer is incremented as in step SG09. In step SG13, it is determined whether or not abnormality detection sensor failure occurrence information is stored in the abnormality occurrence history setting area. If failure occurrence information is not stored, the process proceeds to step SG15, and if stored, the process proceeds to step SG21.

  In step SG15, it is determined whether or not the abnormality occurrence timer is equal to or greater than a predetermined value (for example, a value indicating 1 hour or more). If the abnormality occurrence timer is equal to or greater than the predetermined value, the process proceeds to step SG17.

  In step SG17, abnormality detection sensor failure occurrence information (information indicating failure of the abnormality detection sensor) is stored in the external output signal setting area provided in the RAM 308. In step SG19, abnormality detection sensor failure occurrence information is stored in the abnormality occurrence history setting area. In step SG21, other processing is performed. By executing the device monitoring process in such a procedure, it may be possible to identify and deal with the occurrence of an abnormality such as an illegal act and the failure of the abnormality detection sensor 800.

  As described above, the pachinko machine 100 according to this embodiment has a first coil (in this embodiment, the detection coil 704 of the game ball detection sensor 700) having an inner diameter through which a game ball can pass.

  For this reason, the induced magnetic field detection sensor 800 is not confused with the game ball detection sensor 700, and the assembly and maintenance of the pachinko machine 100 may be improved.

  In the pachinko machine 100, the inner diameter of the first coil 704 and the inner diameter of the second coil 804 are the same. For this reason, it becomes possible to make the coil used for the induction | guidance | derivation magnetic field detection sensor 800 for the game ball detection sensor 700 the same, and a part divertability may improve.

  Further, in the pachinko machine 100, a passing state signal (in this embodiment, indicating the passing state of the game ball based on the magnitude of the voltage dropped by the first coil 704 (in this embodiment, the amplitude value of the oscillation signal). The game ball detection sensor 700 includes a passing state signal output circuit (in this embodiment, the output circuit 706e of the game ball detection sensor 700) that outputs a detection signal), and the magnitude of the voltage dropped by the second coil 804 (this In this embodiment, a magnetic field state signal output circuit (in this embodiment, an output of the abnormality detection sensor 800) that outputs a magnetic field state signal (in this embodiment, a detection signal) indicating the state of the magnetic field based on the amplitude value of the oscillation signal). Circuit) is provided in the induction magnetic field detection sensor 800, and the magnitude of the voltage (in this embodiment, the detection of the game ball is detected) as a threshold for the passing state signal output circuit 706e to change the passing state signal. Than the reference voltage) of the capacitors 700, the magnitude of the voltage field state signal output circuit is a threshold for changing the magnetic field status signal (in this embodiment, toward the abnormal reference voltage of the detection sensor 800) is smaller. For this reason, the occurrence of an abnormality such as an induced magnetic field may be reliably detected.

  Further, in the pachinko machine 100, the first coil 704 is connected to the first waveform shaping circuit (in this embodiment, the detection circuit 706c of the game ball detection sensor 700), and the voltage dropped by the first coil 704 is reduced. The magnitude is indicated by the magnitude of the output voltage of the first waveform shaping circuit 706c, and the second coil 804 is connected to the second waveform shaping circuit (in this embodiment, the detection circuit of the abnormality detection sensor 800).

Or processing of steps SG01 to SG19).

  By adopting such a configuration, in order to determine that an abnormality occurs when the detection signal of the detection object detection means 800 is turned off from on, a new sensor that turns off the sensor output using an induced magnetic field, electromagnetic wave, radio wave, or the like is used. In some cases, abnormalities in a serious case can be detected early. Further, even when the detection object detection means 800 fails, the detection signal of the detection object detection means 800 is turned off from on, so that the failure of the detection object detection means 800 can be detected at an early stage, and illegal acts can be performed more reliably. Can be prevented.

  The pachinko machine 100 further includes game ball payout means (in this embodiment, a payout device 152) for paying out a payout ball, which is a game ball, to the player, and the game ball detection means 700 stores the payout ball in a ball detection area.

For this reason, there is a case where it is possible to detect an illegal act pretending to be detected as a plurality of winning balls by creating a state that cannot be detected when the winning ball detecting means 700 detects one winning ball. is there.

  The abnormality determination unit determines that a failure has occurred when the detection signal from the detection object detection unit 800 cannot be received for a predetermined time or more. For this reason, it may be possible to determine whether the abnormality is caused by the goto action or the abnormality is caused by the failure of the detection object detection means 800.

  Moreover, the detection detection means 800 has a higher detection sensitivity than the game ball detection means 700. For this reason, it becomes possible for the detector detection means 800 to detect radio waves and electromagnetic waves before the game ball detection means 700, and to detect illegal acts reliably and promptly.
