Upon receiving this signal, the random value generation circuit 318 latches the value at the timing of the counter corresponding to the special figure 1 starting port 230, and stores the latched value in the built-in counter value corresponding to the special figure 1 starting port 230. Store in the register. Similarly, when the random value generation circuit 318 receives a signal indicating that the ball has won the special figure 2 starting port 232, the random number generation circuit 318 latches the value at the timing of the counter corresponding to the special figure 2 starting port 232. The latched value is stored in a built-in counter value storage register corresponding to the special figure 2 starting port 232.

  Further, an information output circuit 336 is connected to the basic circuit 302, and the main control unit 300 is connected to an information input circuit 350 provided in an external hall computer (not shown) or the like via the information output circuit 336. 100 game information (for example, game state) is output.

  Further, the main control unit 300 is provided with a voltage monitoring circuit 338 for monitoring the voltage value of the power source supplied from the power source control unit 660 to the main control unit 300. The voltage monitoring circuit 338 has a voltage value of the power source. When the voltage is less than a predetermined value (9 V in this embodiment), a low voltage signal indicating that the voltage has decreased is output to the basic circuit 302.

  Further, the main control unit 300 is provided with a start signal output circuit (reset signal output circuit) 340 that outputs a start signal (reset signal) when the power is turned on, and the CPU 304 starts from the start signal output circuit 340. When a signal is input, game control is started (main control unit main processing described later is started).

  The main control unit 300 includes an output interface for transmitting a command to the first sub-control unit 400 and an output interface for transmitting a command to the payout control unit 600. With this configuration, the first control unit 300 Communication with the sub-control unit 400 and the payout control unit 600 is enabled. Information communication between the main control unit 300 and the first sub-control unit 400 and the payout control unit 600 is one-way communication. The main control unit 300 sends commands and the like to the first sub-control unit 400 and the payout control unit 600. The first sub control unit 400 and the payout control unit 600 are configured such that signals such as commands cannot be transmitted to the main control unit 300.

  Next, the first sub control unit 400 of the pachinko machine 100 will be described. The first sub-control unit 400 includes a basic circuit 402 that controls the entire first sub-control unit 400 mainly based on commands transmitted from the main control unit 300. The basic circuit 402 includes a CPU 404 and A RAM 408 for temporarily storing data, an I / O 410 for controlling input / output of various devices, and a counter timer 412 for measuring time, the number of times, and the like are mounted. The CPU 404 of the basic circuit 402 operates by inputting a clock signal of a predetermined period output from the crystal oscillator 414 as a system clock.

  The basic circuit 402 includes a sound source IC 416 for controlling the speaker 120 (and amplifier), a drive circuit 420 for controlling various lamps 418, and a chance button detection sensor for detecting pressing of the chance button 136. 426, a sensor circuit 428 for outputting a detection signal from a predetermined detection sensor such as a chance button detection sensor 426 to the basic circuit 402, a ROM 406 for storing a control program and various effect data, and a decorative symbol display device (liquid crystal The second sub-control unit 500 for controlling the display device 208 and the shielding device 246 is connected. The ROM 406 may store the control program and various effect data in separate ROMs.

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.

  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. Control of the launch motor 632 that drives the launcher 146 and launcher 148, and control of the ball feeder 634 that supplies the launcher 110 with a ball from the upper plate 126 based on a control signal that indicates the launch intensity according to the amount. I do.

  The power control unit 660 converts the AC power supplied from the outside to the pachinko machine 100 into a DC voltage, converts it to 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 supply control 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 supply control 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.

  Next, with reference to FIGS. 5A to 5C, the special figure 1 display device 212, the special figure 2 display device 214, the decorative symbol display device 208, and the universal figure display device 210 of the pachinko machine 100 are stopped and displayed. The types of figures and ordinary drawings 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 special figure 1 start opening 230, and the special figure 2 start opening 232 indicates that the ball has entered 2 The special figure 2 variable game is started on condition that the start sensor is detected. When the special figure 1 variable game is started, the special figure 1 display device 212 performs “variable display of special figure 1” which repeats lighting of all seven segments and lighting of one central segment. When the special figure 2 variable game is started, the special figure 2 display device 214 performs “variable display of special figure 2” by repeating all lighting of the seven segments and lighting of the central one segment. . These “variation display of special figure 1” and “variation display of special figure 2” correspond to an example of the symbol fluctuation display in the present embodiment. Then, when the variation time determined before the start of the fluctuation of the special figure 1 elapses, the special figure 1 display device 212 stops and displays the stop symbol form of the special figure 1 and the fluctuation time determined before the fluctuation start of the special figure 2 starts. After the elapse, the special figure 2 display device 214 stops and displays the stop symbol form of the special figure 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 embodiment, 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. A series of displays until this is done 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. 5A, the white portions in the figure indicate the segment locations where the light is turned off, and the black portions indicate the location where the segments 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. In addition, after the 15R special big hit game ends and after the 15R big hit game ends, the state shifts to the electric support state (referred to as a short time state together with the variable time reduction state of the special figure variable game). Although the time-short state will be described in detail later, the state that shifts to the time-short state is referred to as a normal high-probability state, and the state that does not shift to the time-short 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 have a relatively high degree of advantage over 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 the first small hit symbol, and “Special figure H” is the second small hit symbol, both of which are in the special figure low probability normal figure low probability state. The small hit here corresponds to the same as the big hit with no short time at 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, which is a symbol that is relatively less advantageous to the player. In the pachinko machine 100 according to the present embodiment, symbols other than “Special Illustration 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 special figure 1 starting port 230 or the special figure 2 starting port 232, that is, the ball has entered the special figure 1 starting port 230, or the special figure 2 Each of the left symbol display area 208a, the middle symbol display area 208b, and the right symbol display area 208c of the decorative symbol display device 208 is provided on the condition that the second start port sensor detects that a ball has entered the start port 232. In the symbol display area, “decoration 1” → “decoration 2” → “decoration 3” →... “Decoration 9” → “decoration 10” → “decoration 1” →. “Change design of symbols”.

  When notifying 15R special jackpot of “Special Figure A” or 15R big jackpot of “Special Figure B”, a combination of symbols in which three same decorative symbols are arranged in the symbol display areas 208a to 208c (for example, “Decoration 1− (Decoration 1 -decoration 1 "," decoration 2 -decoration 2 -decoration 2 ", etc.) are stopped and displayed. When the 15R special jackpot of “special drawing A” is explicitly 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 big hit called “hidden probability change” of “special drawing E”, the 2R big hit called “special drawing F” suddenly normal, or the first small hit of “special drawing G”, “special drawing H” When notifying the second small hit, “decoration 1-decoration 2—decoration 3” is stopped and displayed. Furthermore, in order to notify 2R jackpot called “sudden probability change” of “special drawing C” or 2R jackpot called “sudden time reduction of“ special drawing D ”,“ decoration 1-decoration 3—decoration 5 ”is set. 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 of “normal map 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 the sphere has passed through the general start port 228, the general map display device 210 repeats the lighting of all seven segments and the lighting of one central 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 deviation of the common figure variable game, the “normal figure B” is stopped and displayed. Also in FIG.5 (c), the white part in a figure shows the location of the segment which light-extinguishes, and the black-colored part has shown the location of the segment which lights up.

  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 S101, initial setting 1 is performed. In the initial setting 1, the stack initial value is set to the stack pointer (SP) of the CPU 304 (temporary setting), the interrupt mask is set, the I / O 310 is initialized, the various variables stored in the RAM 308 are initialized, and the WDT 314 is set. Enable operation, set initial values, etc. In the present embodiment, a numerical value corresponding to 32.8 ms (milliseconds) is set in WDT 314 as an initial value.

  In step S103 following step S101, the value of the counter of WDT 314 is cleared, and the time measurement by WDT 314 is restarted. In step S105 subsequent to step S103, whether or not the low voltage signal is ON, that is, the voltage value of the power supply that the voltage monitoring circuit 338 supplies from the power supply control unit 660 to the main control unit 300 is a predetermined value. It is monitored whether or not a low voltage signal indicating that the voltage has decreased when the voltage is less than (9 V in this embodiment). Then, when the low voltage signal is on (when the CPU 304 detects that the power supply is cut off), the process returns to step S103, and when the low voltage signal is off (when the CPU 304 does not detect that the power supply is cut off), the step returns. The process proceeds to S107. Even when the predetermined value (9 V) is not yet reached immediately after the power is turned on, the process returns to step S103, and step S105 is repeatedly executed until the supply voltage becomes equal to or higher than the predetermined value.

  In step S107, initial setting 2 is performed. In the 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, a predetermined port of the I / O 310 (for example, a test output port, a second output port) 1) a process of outputting a clear signal from the output port 1), a setting for permitting writing to the RAM 308, and the like.

In step S109 subsequent to step S107, it is determined whether or not the state before power interruption (before power interruption) is restored. If the state before power interruption is not restored (the basic circuit 302 of the main control unit 300 is changed). In the case of initializing), the process proceeds to initialization processing (step S113). 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 the RAM clear is necessary. If the RAM clear signal is on (when the RAM clear is necessary), the process proceeds to step S113 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 S113 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). When the checksum result is a specific value (eg, 0) (when the checksum result is normal), the process proceeds to step S111 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 S113 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 S113.

  In step S111, 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 S115) 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 S111, a power recovery command is set in the transmission information storage area. This power recovery command is a command indicating that the power has been restored to the state at the time of power-off, and is transmitted to the first sub-control unit 400 in step S233 in the timer interrupt process of the main control unit 300 described later.

  In step S113, 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 S113) of the main control unit 300 has been performed, and in the same way as the power recovery command, in step S233 in the timer interrupt process of the main control unit 300, 1 is transmitted to the sub-control unit 400.

In step S115 subsequent to step S113, the basic random number initial value updating process is performed after setting the interrupt prohibition. In this basic random number initial value update processing, initial value generation for generating an initial value of a special figure determining random value counter for generating a special figure determining random value for use in a lottery for determining a stop symbol in a special figure variable game Update random number counter. In addition, an initial value generation random number counter for generating an initial value of a general winning random number counter for generating a normal winning random number used for determining whether or not the normal game is changed is updated. The RAM 308 of the main control unit 300 is provided with a special figure determining random value counter and its initial value generating random number counter, and a regular winning random number counter and its initial value generating random number counter. In step S115, the initial values of two initial value generation random number counters are updated respectively. For example, if the initial value generation random number counter can take a numerical value range of 0 to 99, a value is acquired from the initial value generation random number counter, 1 is added to the acquired value, and then the original initial value generation random number counter is obtained. To remember. At this time, if the result of adding 1 to the acquired value is 100, 0 is stored in the original initial value generation random number counter. The other initial value generation random number counters are similarly updated. Note that the initial value generation random number counter is also updated in step S207 described later. The main control unit 300 repeatedly executes the process of step S115 except during a timer interrupt process that starts every predetermined period.

  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 S201, a timer interrupt start process is performed. In this timer interrupt start process, a process of temporarily saving each register value of the CPU 304 to the stack area is performed. In step S203 following step S201, the WDT is set so that the count value of the WDT 314 exceeds the initial set value (32.8 ms in the present embodiment) and no WDT interrupt occurs (so as not to detect a processing abnormality). It is restarted periodically (in this embodiment, once every 2 ms, which is the main controller timer interrupt period).

  In step S205 subsequent to step S203, input port state update processing is performed. In this input port state update process, the detection signals of various sensors 320 including the above-mentioned front frame door open sensor, inner frame open sensor, lower pan full sensor, and various ball detection sensors are input via the input port of the I / O 310. The input is monitored for the presence or absence of a detection signal, and stored in a signal state storage area provided for each of the various sensors 320 in the RAM 308. If the detection signal of the sphere detection sensor is described as an example, information on the presence / absence of the detection signal of each sphere detection sensor detected in the timer interruption process (about 4 ms before) is stored in the RAM 308 for each sphere detection sensor This information is read out from the previous detection signal storage area partitioned and stored in the RAM 308 in the previous detection signal storage area partitioned for each sphere detection sensor, and the previous timer interrupt processing (about 2 ms before) ) Is read from the current detection signal storage area provided for each sphere detection sensor in the RAM 308, and this information is read out from the previous detection signal storage area described above. To remember. Further, the detection signal of each sphere detection sensor detected this time is stored in the above-described current detection signal storage area.

Further, in step S205, the information on the presence or absence of the detection signal of each sphere detection sensor stored in each storage area of the above-mentioned detection signal storage area, the previous detection signal storage area, and the current detection signal storage area is compared. It is determined whether or not the information on the presence or absence of detection signals for the past three times in the ball detection sensor matches the winning determination pattern information. This main control unit timer interrupt process that is repeatedly started at a very short interval of about 2 ms while one game ball passes one ball detection sensor is started several times. For this reason, every time the main control unit timer interrupt process is activated, a detection signal indicating that the same game ball has passed the same ball detection sensor is confirmed in step S205. 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 step S205, information on the presence or 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). If it matches with the information (indicating that there is), the entry to the general winning opening 226, the variable winning opening 234, 235, the special figure 1 starting opening 230, and the special figure 2 starting opening 232, or the ordinary figure starting opening 228 It is determined that there was a passage. 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 S207 and step S209 following step S205, basic random number initial value update processing and basic random number update processing are performed. In these basic random number initial value update processing and basic random number update processing, the initial value generation random number counter performed in step S115 is updated, and then a special figure determination random number value used in the main control unit 300 is generated. The special figure determining random value counter and the common figure winning random value counter for generating the common winning random value are updated. For example, when the numerical value range that can be taken as the special figure determination random value is 0 to 99, the value is acquired from the special figure determination random value counter provided in the RAM 308 in order to generate the special figure determination random value. After adding 1 to the value, it is stored in the original special figure determination random value counter. At this time, if the result of adding 1 to the acquired value is 100, 0 is stored in the original special figure determination random value counter. If it is determined that the special figure determination random value 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 the special figure determination random value counter is acquired. And set in the special figure determination random value counter. For example, a value is acquired from a special figure determination random value counter that fluctuates in a numerical value range of 0 to 99, 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. When the value is equal to the previously set initial value (for example, 7), a value is acquired as an initial value from the initial value generation random number counter corresponding to the special figure determination random value counter, and the special figure determination random value counter In addition to setting, the initial value set this time is stored in the above-described initial value storage area in order to determine that the special figure determination random value counter has made one round next. In addition to the initial value storage area for determining that the special figure determining random value counter has made one round next, an initial value storage for determining that the common figure winning random number counter has made one round An area is provided in the RAM 308. The special figure determining random value counter may be provided with a counter for acquiring the random number value for special figure 1 and a counter for acquiring the random value for special figure 2 or the same counter. May be used.

  In step S211 following step S209, 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. Specifically, the value of the special figure timer number determining random value counter for generating the special figure timer number determining random value for determining the symbol changing time in the special figure changing game or its initial value is updated. In addition, the value of the random number value counter for determining the general-purpose timer number for determining the random time value for determining the general-purpose timer number for determining the symbol variation time in the general-purpose variable game or its initial value is updated.

  In step S213 following step S211, timer update processing is performed. In this timer update process, the time for displaying and changing the symbol on the special symbol display device 212 and the time for displaying and changing the symbol on the special symbol display device 212 are counted. Special figure 1 display symbol update timer, Special figure 2 display symbol update timer for measuring the time for the symbol to be changed / stopped on the special figure 2 display device 214, a predetermined winning effect time, a predetermined opening time, a predetermined time Various timers including a timer for counting the closing time, a predetermined end effect period, and the like are updated.

  In step S215 subsequent to step S213, a winning opening counter updating process 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 S217 following step S215, a winning acceptance process is performed. In the winning acceptance process, it is determined whether or not there has been a winning at the special figure 1 starting port 230, the special figure 2 starting port 232, the ordinary drawing starting port 228, and the variable winning ports 234 and 235. Here, the determination is made using the determination result of whether or not it matches the winning determination pattern information in step S205.

  If there is a winning at the special figure 1 starting port 230 and the corresponding special figure 1 reserved number storage area provided in the RAM 308 is not full (in this example, the full number is 4), the random number value generation circuit (Hard Random Number Circuit) A jackpot determination random number value generated by applying predetermined processing to a value stored in a built-in counter value storage register corresponding to the starting port 230 of the special figure 1 of 318 is provided in the RAM 308. The special figure determining random value is acquired from the special figure determining random value counter and stored in the special figure 1 random value storage area in the acquisition order. A set of the jackpot determination random value and the special figure determination random value in the special figure 1 random value storage area (hereinafter abbreviated as "special figure 1 random value set") is stored in the special figure 1 reserved number storage area. The same number as the number of reserved special figure 1 held is stored. In the special figure 1 random value storage area, each time the special figure 1 holding number decreases, the data of a set of special figure 1 random values having the highest holding order (the first and most recently stored) is stored. In addition to being erased, the remaining special figure 1 random value set data is processed so that the holding order is incremented by one. Each time the special figure 1 holding number increases by one, the new special figure 1 random value set data is added to the next holding order of the special figure 1 random value set data having the lowest (last) holding order. Written.

  When the special figure 2 starting port 232 is won and the corresponding special figure 2 reserved number storage area provided in the RAM 308 is not full (in this example, the reserved number 4 is full), the random value generation circuit A special jackpot determination random number value generated by performing predetermined processing on the value stored in the built-in counter value storage register corresponding to the start port 232 of the special figure 2 of 318 is acquired, and the special jackpot special feature provided in the RAM 308 is acquired. The big hit special figure determining random value is acquired from the figure determining random value counter and stored in the special figure 2 random value storage area in the order of acquisition. Special figure 2 random number value for jackpot determination and special figure determination random number value for big hit time (hereinafter abbreviated as "special figure 2 random value group") in the special figure 2 random value storage area The same number as the number of reserved special figure 2 stored in the area is stored. In the special figure 2 random value storage area, each time the special figure 2 holding number is decreased, the data of the special figure 2 random value pair with the highest holding order is erased, and the remaining special figure 2 random number values are stored. Processing is performed so that the holding order of the set of data is incremented by one. Each time the special figure 2 holding number increases by one, the new special figure 2 random value set data is written in the next holding order of the special figure 2 random value set data having the lowest holding order.

  If there is a winning at the general figure starting port 228 and the corresponding general figure holding number storage area provided in the RAM 308 is not full, the value is acquired from the general figure winning random number counter as the normal winning random number Store in the usual random number storage area. When there is a winning at the variable winning opening 234, 235, information indicating that a ball has entered the variable winning opening 234, 235 is stored in the winning storage area for the variable winning opening.

In step S219 following step S217, 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 S221 following step S219, 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 general diagram state update process in the middle of the normal map change display (the value of the above-mentioned general map display symbol update timer is 1 or more), the 7 segment LED constituting the general map display device 210 is repeatedly turned on and off. Turns off drive control. By performing this control, the general map display device 210 performs normal variable display (normal map variable game).

  Also, in the general state update process at the timing when the normal map change display time has elapsed (the timing at which the value of the general map display symbol update timer has changed from 1 to 0), When the 7-segment LED constituting the general-purpose display device 210 is turned on / off to control the display mode, and the normal-map hit flag is off, the general-purpose display is displayed so that the display mode of the off symbol is displayed. The 7 segment LED constituting the device 210 is controlled to be turned on / off. 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 on / off 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 universal symbol display device 210 determines one of the winning symbols (common symbol A shown in FIG. 5 (c)) and the off symbol (general symbol B shown in FIG. 5 (c)). Display. Thereafter, information indicating the stop period is set in a storage area of a normal stop time management timer provided in the RAM 308 in order to maintain the display for a predetermined stop display period (for example, for 500 ms). With this setting, the symbol that has been confirmed and displayed is stopped and displayed for a predetermined period, and the player is notified of the result of the normal game.

  Further, if the result of the usual figure variable game is a hit, the usual figure hit flag is turned on as will be described later. When the usual figure hit flag is on, in the usual figure state update process at the timing when the predetermined stop display period ends (when the usual figure stop time management timer value changes from 1 to 0), A normal operation is set in the setting area, and a predetermined opening period (for example, 2 seconds), a solenoid for driving to open / close the blade member 232a of the special opening 2 232 (a part of various solenoids 332) A signal for holding the 232a in the open state is output, and information 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. Further, if the result of the usual figure variation game is out of place, the usual figure hit flag is turned off as will be described later. In the case where the usual figure hit flag is off, even in the usual figure state update process at the timing when the predetermined stop display period described above ends (when the value of the usual figure stop time management timer is changed 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 operating, nothing is done and the process proceeds to the next step S223.

In step S223, 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 special map 2 starting port 232 is not performed (the state of the general map is not operating),
In addition, when the number of pending general variable games is one or more, the result of the general variable game by random lottery based on the random number value stored in the general random number value storage area described above A hit determination for determining whether or not to win is made, and in the case of winning, an ON is set for a flag for a normal figure provided in the RAM 308. In the case of unsuccessful election, the flag for the usual figure is set to OFF. Also, regardless of the result of the hit determination, the value of the random number value counter for determining the normal timer number for generating the normal timer number determining random value is obtained as the random number value for determining the normal timer number. Based on the random number value for determining the general-purpose timer number, one time for displaying the general-purpose figure on the general-purpose display device 210 is selected from a plurality of variable times, and this variable display time is set as the normal-type variable display time. , It is stored in the usual variable time storage area provided in the RAM 308. In addition, the number of pending general figure variable games is stored in the usual figure pending number storage area provided in the RAM 308, and from the number of pending custom figure variable games each time a hit determination is made. The value obtained by subtracting 1 is re-stored in the usual figure number-of-holds storage area. Also, the random number value used for the hit determination is deleted.

  Next, the special figure state update process for each of the special figure 1 and the special figure 2 is performed. First, the special figure state update process (the special figure 2 state update process) for the special figure 2 is performed (step S225). In the special figure 2 state update process, one of the following plural (in this example, nine) processes is performed in accordance with the special figure 2 state.

  For example, in the special figure 2 state update process at the timing of the special figure 2 fluctuation start, a value obtained by subtracting 1 from the value of the special figure 2 holding number stored in the special figure 2 holding number storage area provided in the RAM 308 is shown in FIG. Re-store in the reserved number storage area. At the same time, the blinking of the special figure 2 holding lamp 220 is controlled. For example, if the four LEDs of the special figure 2 holding lamp 220 in FIG. 3 are LED numbers 1-4 in order from the left to the right in the figure, the LEDs corresponding to the special figure 2 holding number are red, for example, in order from the smallest LED number. Turn on and turn off the others.

  Also, for example, in the special figure 2 state update process in the middle of the special figure 2 fluctuation display (the value of the special figure 2 display symbol update timer described above is 1 or more), the 7-segment LED constituting the special figure 2 display device 214 is turned on. Performs lighting / extinguishing drive control that repeatedly turns off. By performing this control, the special figure 2 display device 214 performs the special figure 2 variable display (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 S233) is additionally stored in the above-described 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 off, 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 this case, the 7 segment LED constituting the special figure 2 display device 214 is controlled to be turned on / off so that the special figure I is turned on and the special figure J is turned on when the special flag I is turned on. Is set to indicate that the special figure 2 stop display is in progress. By performing this control, the special figure 2 display device 214 has the 15R special jackpot symbol (special chart A), the 15R jackpot symbol (
Special Figure B), Sudden Probability Change Pattern (Special Figure C), Sudden Short-Time Design (Special Figure D), Hidden Probability Change Pattern (Special Figure E), Sudden Normal Design (Special Figure F), First Small Hit Pattern (Special Figure G) ), The second small hit symbol (special symbol H), the first off symbol (special symbol I), and the first off symbol (special symbol J). Thereafter, information indicating the stop period is set in the storage area of the special figure 2 stop time management timer provided in the RAM 308 in order to maintain the display for a predetermined stop display period (for example, for 500 ms). With this setting, the specially displayed special figure 2 is stopped and displayed for a predetermined period, and the result of the special figure 2 variable game is notified to the player. Also, if the electric support number stored in the RAM 308 is 1 or more, the subtraction result is changed from 1 to 0. In this case, if the special figure probability is not changing (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 S233) 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 S233) 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) Or until the opening of the door member 234a of the variable prize opening 234 and the shutter 800 of the variable prize opening 235 are detected. A signal for holding the door member 234a and the shutter 800 in the open state is output to the opening / closing shutter driving solenoid 760, and information indicating the opening period is set in the storage area of the door opening time management timer provided in the RAM 308. To do. In addition, predetermined transmission information indicating that the special winning opening release setting transmission process is executed in the command setting transmission process (step S233) 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 and the shutter 800 in a closed state is output to a solenoid for opening and closing the door member 234a of the variable prize opening 234 and a shutter driving solenoid 760 for opening and closing the shutter 800 of the variable prize opening 235. At the same time, information indicating the closing period is set in the storage area of the door closing time management timer provided in the RAM 308. In addition, predetermined transmission information indicating that the special winning opening closing setting transmission process is executed in the command setting transmission process (step S233) 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. In addition, if the ordinary probability fluctuation flag is set to ON, at the same time as the end of the jackpot game, RA
The electric support number (for example, 100 times) is set in the electric support number storage unit provided in M308, and the time flag provided in the RAM 308 is turned on. If the usual probability fluctuation flag is set to OFF, the power support count storage unit does not set the power support count, and the time reduction flag is not turned ON. The short-time state 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 in the normal figure high probability (normal figure certain change) state. There is a higher probability of hitting in the general-game variable game in the high-probability state than in the normal-game low-probability state. In addition, in the normal figure high probability state, the fluctuation time of the general figure variable game is shorter than in the normal figure low probability state (normal figure variable short). Furthermore, in the normal high probability state, compared to the normal low probability state, the opening time in one opening of the pair of blade members 232a of the special drawing 2 starting port 232 is likely to be longer (electrical chew extension). 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. The control state due to the universal figure change, the universal figure change, and the electric Chu extension is collectively referred to as an electric support (starting prize winning support by electric tulip) state. In addition, a time-short state including a control state in which the fluctuation time of the special figure variable game is also shortened is called.

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 big hit game. This is because, if the game is in a high probability state during a big hit game, a predetermined number of variable winning holes 234 and 235 will be placed in the special figure 2 start opening 232 during the big hit game until a game ball enters. There is a problem that game balls enter and the number of game balls that can be acquired during a big hit 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 S233) 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 place, the out-of-game flag is turned on as will be described later. When this 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 in operation, nothing is done and the process proceeds to the next step S227.

  Subsequently, special figure state update processing (special figure 1 state update process) for special figure 1 is performed (step S227). 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 S225 and step S227 is completed, a special figure related lottery process for each of special figure 1 and special figure 2 is performed. Also here, first, a special drawing related lottery process for special figure 2 (a special drawing 2 related lottery process) is performed (step S229), and then a special drawing related lottery process for special figure 1 (a special drawing 1 related lottery process). ) Is performed (step S231). 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. In addition, when the number of special figure 2 variable games held is larger than 0, the lottery process and the variable game related to the special figure 1 variable game hold are not performed. 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 special figure 2 starting port 232 is notified. 1 is performed in preference to the notification of the lottery result of the lottery based on the winning at the starting port 230. In the case of the special figure 2 related lottery process (step S229), a special figure 2 random value set (starting information) is obtained from the first (most recently stored) holding position in the special figure 2 random value storage area. Obtaining and determining whether or not to make a big hit, determining whether or not to make a big hit using a determination table (not shown), and determining the time from the start of the variable display in FIG. 2 to the stop display Then, determination of a symbol (stop symbol) to be stopped and displayed after the fluctuation display of the special symbol 2 is performed. After the first special figure 2 random value set is extracted from the special figure 2 random value storage area, the storage of the special figure 2 random value set in the special figure 2 random value storage area is cleared, and the special figure 2 Subtract 1 from the number of holds. At this time, the set of the special figure 2 random value extracted from the special figure 2 random value storage area is stored in the temporary area (an example of the second starting information storage means) provided in the RAM 308, You may make it perform the above-mentioned determination based on the group of the said special figure 2 random value memorize | stored in this temporary area | region.

  In step S233 following step S231, 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, FRAM 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 or off by the command transmission process described above. If the command type is a symbol variation start command, the command data includes 15R jackpot flag and 2R jackpot flag values stored in the RAM 308 of the main control unit 300, special chart probability variation flag values, and special chart related items. It includes information indicating the timer number selected in the lottery process, and in the case of a symbol variation stop command, includes the value of the 15R jackpot flag, 2R jackpot flag, the value of the special figure probability variation flag, etc. In the case of the production start command, the value of the special figure probability variation flag is included, and in the case of the big hit round number designation command, the value of the special figure probability variation flag, the big hit number of rounds, and the like are included. When the command type indicates a basic command, device information in the command data, presence / absence of winning in the special figure 1 starting port 230, presence / absence of winning in the special figure 2 starting port 232, winning in the variable winning ports 234 and 235 Includes presence or absence.

In the rotation start setting transmission process described above, the value of the 15R big hit flag or 2R big hit flag, the value of the special figure probability variation flag, the special figure 1 related lottery process, and the special figure 2 related are stored in the RAM 308 as command data. Information indicating the timer number selected in the lottery process, the number of the special figure 1 variable game or the special figure 2 variable game being held, and the like are set. In the rotation stop setting transmission process described above, information indicating the value of the 15R big hit flag, the value of the 2R big hit 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 special figure 1 variable game or the special figure 2 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 special figure 1 variable game or the special figure 2 variable game being held, etc. is set. In the above-described winning prize opening release 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 number of special figure 1 variable games or special figure 2 variable games held, etc. Set the information indicating.
In the above-described winning prize 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 number of special figure 1 variable games or special figure 2 variable games held, etc. Set the information indicating. In step S233, 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 S235 following step S233, external output signal setting processing 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 S237 following step S235, 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 S205 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 presence or absence of a full tray 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 special figure 2 starting port 232 and the variable prize winning ports 234 and 235, and the general diagram display device 210 and the special figure 1 display via the drive circuits 324, 326 and 330. Display data to be output to the device 212, the special figure 2 display device 214, the various status display unit 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 S219) is output to the first sub-control unit 400 via the output port (I / O 310).

  In step S239 following step S237, 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 S243, and when the low voltage signal is off (when power supply cutoff is not detected), the process proceeds to step S241.

An angle between the inclined upper plane and the lower plane is, for example, 25 degrees to 30 degrees. Since the shutter front end portion 800b of the shutter 800 is formed thin, the area that becomes a contact point when the shutter 800 and the game ball come into contact with each other can be reduced, and the possibility of ball engagement can be reduced. Since the upper surface side of the shutter front end portion 800b is inclined, it is possible to release the force when the game ball is caught between the corner portions of the uneven portion 900.

  A driving member connecting portion 800c is provided at substantially the center of the rear side edge of the shutter flat surface portion 800a. The driving member connecting portion 800c has a recess that is open on the lower side and into which the upper end side of the third plate portion 750e of the shutter driving member 750 is inserted.

  The third plate portion of the shutter driving member 750 is inserted into the concave portion of the driving member connecting portion 800c while the left and right side surface portions of the shutter 800 are inserted into the left and right rail members 752 and 754 with the driving member connecting portion 800c side of the shutter 800 facing rearward. The shutter 800 and its drive system are configured by inserting the upper end side of 750e.

  The shutter drive system accommodating portion 770 has a spherical passage 770c formed on the right side of the shutter drive plate accommodating portion 770b. Further, a sensor housing portion 770d is formed on the right side of the ball passage 770c. A predetermined sensor 762 is disposed in the sensor housing portion 770d.

  The shutter driving system accommodating portion 770 accommodating the shutter driving member 750, the shutter driving solenoid 760, the shutter 800, and the like is attached to the back surface of the base cover 740 that is screwed to the back surface of the winning device base 720. It is fixed to the base cover 740 with a screw 748. A closed portion is provided at a predetermined position on the back surface of the base cover 740 so as to block the opening of the bearing portion so that the shaft of the shaft portion 750b of the shutter drive plate does not fall off from the bearing portion of the shutter drive plate housing portion 770b. Yes. Further, the upper surface of the shutter accommodating roof rear portion 770f of the shutter drive system accommodating portion 770 substantially coincides with the upper surface of the shutter accommodating roof front portion 720f.

FIG. 10 is a perspective view of the assembled shutter-type winning device 700. FIG. 10 (a) and 10 (b) both show the shutter type winning device 700 from the front to the rear from the lower left to the upper right. FIG. 10A shows a state in which the shutter 800 appears and blocks the opening surface of the variable prize winning opening 235. In the state shown in FIG. 10A, the shutter driving solenoid 760 is not driven, the movable iron core 670c is pushed downward by the spring, and the third plate portion 750e is in the initial position through the driving member connecting portion 800c. In this state, 800 is pushed forward. As a result, the shutter 800 appears from the shutter retracting opening 720b, the shutter tip 800b contacts the front surface rear surface 710b, the opening surface of the variable winning opening 235 is closed, and the variable winning opening 235 is closed. .

  Further, the left end of the shutter tip 800b appears above the non-winning ball passage 710g, and the right end appears so as to partially cover the right side 710d to close the opening surface of the variable winning opening 235. The shutter flat surface portion 800a is inclined so as to descend from the right to the left, and functions as a spherical passage. Since the space above the opening surface of the variable winning opening 235 is made as wide as possible, the game ball riding on the upper part of the shutter 800 can be quickly allowed to flow down when the shutter 800 is closed. For example, a ball that has reached the ball passage 712 bounces or rolls, passes through the shutter flat surface portion 800a on the variable winning opening 235, rolls or jumps over the non-winning ball passage 710g, and flows down to the lower left. .

  FIG. 10B shows a state in which the shutter 800 is retracted and the opening surface of the variable prize winning opening 235 appears. In the state shown in FIG. 10B, when the shutter driving solenoid 760 is in a driving state, the magnetic force of the electromagnet is greater than the force of the spring and the movable iron core 670c is raised, and the upper end side of the third plate portion 750e is moved backward from the initial position. In this state, the shutter 800 is moved rearward via the driving member connecting portion 800c. In this state, the shutter 800 is retracted behind the shutter retracting opening 720b, the opening surface of the variable winning opening 235 appears, and the variable winning opening 235 is opened. As described above, the shutter 800 can appear and disappear in the space S including the upper left end of the left side surface 710c of the variable winning opening defining unit 710, the upper right end of the right side 710d, and the upper end 710i of the front surface 710a. ing. When the opening surface of the variable prize opening 235 appears as shown in FIG. 10B, for example, the ball that has reached the ball passage 712 bounces or rolls and passes through the space S and the opening surface with high probability. To enter the variable prize opening 235.

  When there is a ball in the special drawing 1 or special drawing 2 starting ports 230 and 232 and the determination result is 15R special big hit by the related lottery processing (steps S229 and S231 in FIG. 7) of the special drawing 1 or special drawing 2, the main control is performed. In the jackpot game after the end of the special figure variable game, the unit 300 controls the moving operation of the shutter 800 by the state update process of the special figure 1 or the special figure 2 (steps S225 and S227 in FIG. 7). At this time, based on the control of the first sub-control unit 400 (step S315 in FIG. 8), the light emission from the light emitting unit 730a facing the rear lower side of the opening surface of the variable winning port 235 during the big hit game The shutter-type winning device 700 shines by the light emitted from the light emitting unit 730b.

  FIG. 11 shows the assembled shutter-type winning device 700. FIG. 11A is a perspective view of the shutter-type winning device 700 as viewed from a position shifted from the upper right to the right rear. The front side of the shutter-type winning device 700 is shown on the left side of the drawing, and the left side is shown on the upper side of the drawing. ing. FIG. 11B shows a state in which the shutter-type winning device 700 is viewed from directly above, with the front side of the shutter-type winning device 700 shown on the left side and the left side shown on the upper side of the drawing. FIGS. 11A and 11B show the state of FIG. 10B in which the shutter 800 is submerged in the shutter protrusion / disengagement opening 720b and the opening surface of the variable winning opening 235 is exposed.

As shown in FIGS. 11A and 11B, an uneven portion 900 extending substantially in parallel with the upper end side 710i is formed in the vicinity of the upper end side 710i of the front surface rear surface 710b. The uneven portion 900 is formed in the space S above the position where the shutter 800 appears. The uneven portion 900 is formed integrally with, for example, the variable prize opening defining portion 710, and a plurality of inclined portions having substantially the same shape are discretely arranged in a line on the upper surface of the convex beam portion extending along the upper end side 710i. Have a structure. The slope portion has an inclined plane extending from the vicinity of the upper end side 710i of the front surface rear surface 710b toward the rear lower side, and has a schematic shape of a triangular prism having the inclined plane as one side surface. This shape is formed in the left-right direction at the uneven portion 900. With this shape, when the game ball flowing down from above hits the inclined plane, the game ball can be dropped to the rear side of the variable winning opening 235. Further, the corners of the front surface rear surface 710b and the lower surface of the convex beam portion are concave portions of the uneven portion 900. Details of the uneven portion 900 will be described later with reference to FIG.

  As shown in FIGS. 11 (a) and 11 (b), the spherical alignment of the planar plate-like portion is almost perpendicular to the front surface back surface 710b at the intersection angle between the front surface back surface 710b and the right wall surface 710d. One member 910 is formed. The first spherical alignment member 910 is formed integrally with the left wall surface of the front surface rear surface 710b and the right side surface portion 710d below the uneven portion 900, for example. The first spherical alignment member 910 includes a rear end side extending in parallel to the left side at a predetermined distance from the left wall surface of the right side surface portion 710d with respect to the front surface rear surface 710b, and a front surface rear surface 710b extending from the rear end side to the left front. It has a straight beveled edge that touches.

  The width between the front surface back surface 710b and the surface of the base flat surface portion 720a is, for example, about 1.3 to 1.6 times the diameter (11 mm) of the game ball, and preferably about 1.5 times. It has become. Similarly, the width from the front surface rear surface 710b of the first ball alignment member 910 to the rear edge is, for example, about 0.3 to 0.5 times the diameter of the game ball, and preferably about 0.4 times. Is set to For this reason, the plate-like portion of the ball alignment first member 910 is formed so as to protrude smaller than half of the game balls from the front surface rear surface 710b side, so that the game balls ride on the ball alignment first member 910. It is designed not to be stupid. In addition, it is possible to reduce side friction caused by rolling of the game ball.

  As shown in FIG. 11 (b), the length of the rear end side of the ball alignment first member 910 viewed from directly above is, for example, about 1.3 to 1.6 times the diameter of the game ball. Is about 1.5 times. Similarly, the length of the oblique end side of the ball alignment first member 910 is, for example, about 0.6 to 1.0 times the diameter of the game ball, and preferably about 1.0 times. As shown in FIG. 11 (b), when viewed from directly above, the rear inclined surface 710h is partially hidden at the rear end side of the ball alignment first member 910 and is observed in a substantially square shape on which one game ball can be placed. Is done.

  When the game ball comes into contact with the rear end side or the oblique end side of the ball alignment first member 910, the bottom surface portion first inclined plane 710e, the bottom surface portion second inclined plane 710f, and the rear inclined surface 710h are constituted by the bottom inclined portions. It is possible to align the balls flowing down by gradually narrowing the rollable width (or region) of the game ball on the downstream side of the ball path. This makes it possible to align the game balls toward the ball detection sensor 732 as the ball detection sensor 732 is approached. In addition, the clogging of the ball passage in the variable prize winning opening 235 can be eliminated.

  As shown in FIGS. 11A and 11B, a flat thin plate-like sphere alignment second member 920 is formed so as to intersect with the sphere alignment first member 910. The second spherical alignment member 920 rises from the rear inclined surface 710h and is substantially parallel to the left wall surface of the right side surface portion 710d and substantially perpendicular to the front surface rear surface 710b. For example, the second ball alignment member 920 is integrally formed with the rear surface 710b, the first ball alignment member 910, and the rear inclined surface 710h. The second spherical alignment member 920 includes a rear end side extending in parallel upward from the rear inclined surface 710h by a predetermined distance to the front surface rear surface 710b, and a straight line extending forward from the upper end portion of the rear end side and in contact with the front surface rear surface 710b. And an upper end side of the shape.

  The width from the front surface rear surface 710 b to the rear end side of the ball alignment second member 920 is substantially the same as that of the ball alignment first member 910. The distance from the left wall surface of the right side surface portion 710d of the second ball alignment member 920 is, for example, about 0.3 to 0.5 times the diameter of the game ball, and preferably about 0.4 times. For this reason, the game ball is prevented from riding on the ball alignment second member 920.

The first sphere alignment member 910 has a right side surface portion 71 on the downstream side from the upper side of the bottom surface portion first inclined plane 710e.
The second ball aligning member 920 is formed so as to protrude from the left wall surface of the right side surface portion 710d on the downstream side at a position shorter than the half of the game balls. Thereby, it may be possible to prevent the game ball from getting on between the left wall surface of the right side surface portion 710d and the ball alignment second member 920.

  When the game ball comes into contact with the upper end side or the rear end side of the ball alignment second member 920, the game ball stays above the rear inclined surface 710h, or by winning the game ball from the upper side of the ball alignment first member 910, It is possible to eliminate the game ball from being placed above the ball alignment first member 910.

  FIG. 12 is a diagram for explaining in more detail the uneven portion 900, the ball alignment first member 910, the ball alignment second member 920, and the like of the shutter-type winning device 700. FIG. 12A shows the region including the concavo-convex portion 900, the sphere alignment first member 910, and the sphere alignment second member 920 extracted from FIG. 11A. FIG. 12B shows a cross section of the variable winning opening 235 cut in the vertical direction along the line AA in FIG.

  As shown in FIGS. 12A and 12B, the concavo-convex portion 900 has a convex beam portion 900a, a slope portion 900b, and a plane portion 900c. The convex beam portion 900a protrudes from the front surface rear surface 710b and is formed between the upper end side 710i and the opening surface of the variable winning opening 235 so as to be substantially parallel to them, and has an elongated rectangular parallelepiped shape. The cross-sectional shape perpendicular to the front surface back surface 710b of the convex beam portion 900a is such that the length of the side in the vertical direction is about 0.14 times the diameter of the game ball, for example, and the length of the side in the front and back direction is, for example, It is a rectangular shape about 0.2 times the diameter of the game ball. The distance from the lower end side on the front surface rear surface 710b side of the convex beam portion 900a to the upper end side 710i is, for example, about 0.6 times the diameter of the game ball.

  The slope portion 900b has an inclined plane having an upper end side that intersects the front surface rear surface 710b slightly below the upper end side 710i and a lower short side that contacts the upper end side of the protruding end of the convex beam portion 900a. Yes. The distance between the upper end side and the lower short side of the inclined plane is, for example, about 0.4 times the diameter of the game ball. The widths of the upper end side and the lower short side of the inclined plane are both about 0.14 times the diameter of the game ball, for example.

  Since the concavo-convex portion 900 is configured to include a slope portion 900b that is inclined backward as it goes downward, the area of the top of the concavo-convex portion 900 can be reduced so that a game ball does not get on it. Further, the slope portion 900b can have one contact point with the game ball.

  The plane portion 900c is provided between the left side surface of one slope portion 900b of the two adjacent slope portions 900b and the right side surface of the other slope portion 900b, and is formed by the upper plane of the convex beam portion 900a. . The width in the left-right direction of the plane portion 900c, that is, the distance between the left side surface of one of the two slope portions 900b and the right side surface of the other slope portion 900b is, for example, about 0.14 of the diameter of the game ball. It is formed about twice. The corners of the lower surface of the convex beam portion 900 a and the front surface rear surface 710 b become the concave portions of the uneven portion 900.

  In FIG. 12B, the area between the lower surface of the convex beam portion 900a and the opening surface of the variable prize winning opening 235 is an appearance area of the shutter 800. Since the interval between the concave and convex portion 900 of the in / out area and the appearance position of the shutter 800 is set to be narrower (shorter) than the width of one game ball, the game ball enters the in / out area when the shutter 800 is closed. There is nothing. The optimal distance is a little less than half a game ball. The uneven portion 900 is formed across the left and right direction of the shutter 800. Thereby, it becomes possible to prevent the ball biting over the entire variable winning opening 235.

Further, as shown in FIG. 12B, the ball alignment first member 910 has a bottom surface portion second inclined plane 71.
A plane portion substantially parallel to the second reference plane, which is a plane including 0f, is provided. The plane portion of the ball alignment first member 910 is provided at a height of about 0.5 times the diameter of the game ball, for example, from the second reference plane. The first ball alignment member 910 may be slightly inclined rearward and downward rather than perpendicular to the front surface rear surface 710b. Moreover, as shown in FIG.12 (b), the ball | bowl alignment 2nd member 920 is standing up from the front center vicinity of the back inclined surface 710h.

  As shown in FIG. 3, the game nail 238 above the variable winning opening 235 is not provided almost directly above the center of the opening surface of the variable winning opening 235. Most of the game balls flowing down from the right side of the game area 124 jump in the lower left direction from the area where the game nail 238 just above the variable prize opening 235 is not provided toward the opening surface of the variable prize opening 235. That is, in the illustration in FIG. 12B, most of the winning balls fall on the bottom surface first inclined plane 710e and the bottom surface second inclined plane 710f located below the right half of the opening surface.

  Below the bottom surface portion first inclined plane 710e and the bottom surface portion second inclined plane 710f, a bottom surface back surface 710j substantially parallel to the horizontal surface is provided. Ribs 710k are provided between the bottom surface second inclined plane 710f and the bottom surface back plane 710j at a predetermined interval d shorter than the diameter of the game ball. Thereby, for example, the rigidity of the bottom surface second inclined plane 710f is enhanced as compared with the front surface back surface 710b and the like, and the game ball is prevented from excessively splashing on the bottom surface second inclined plane 710f, and once won. The game ball is prevented from jumping out of the variable winning opening 235 again.

  As described above, both the inclination of the shutter flat surface portion 800a of the shutter 800 and the inclination of the concavo-convex portion 900 on the front surface rear surface 710b side are parallel to the first reference plane, and the inclination of the bottom surface second inclination surface 710f is the first reference plane. And the second reference plane on the opposite side across the horizontal plane. As a result, the game balls won in the shutter-type winning device 700 while reducing the number of wasted balls by hitting right (the way of hitting the game balls to the right side of the game area 124) are the bottom face first slope plane 710e and the bottom face second slope. After the direction is changed by the plane 710f, it reaches the rear inclined surface 710h and is guided to the sphere detection sensor 732 at the tip. For this reason, it is possible to expect an over-winning in which a game ball that has already passed the opening surface of the variable winning opening 235 when the predetermined number of balls is detected by the ball detecting sensor 732 can be counted. Thereby, interest can be improved.

  Next, a mechanism capable of suppressing the ball biting state will be described using FIG. 13 and FIG. 14 while schematically illustrating the ball biting operation between the shutter and a plurality of types of wall planes. Each of FIGS. 13 and 14 shows a state in which the tip of the shutter T and the wall W, which operate in the same manner as the shutter 800 of the present embodiment, are in contact with the game ball B, parallel to the wall surface of the wall W. A cross section cut along a plane perpendicular to a horizontal line is schematically shown. In each of FIGS. 13 and 14, unless otherwise specified, the horizontal direction is the horizontal direction (positive (+) for the right direction and negative (-) for the left direction), and the vertical direction (upward) in the figure unless otherwise specified. Is positive (+) and downward is negative (-)). 13 and 14, the wall portion W is shown on the left side of the drawing, and the shutter T is shown on the right side. In the description of FIG. 13 and FIG. 14 and FIG. 15, it is assumed that the kinetic energy due to the rotation or flow of the game ball B is ignored and each element is in a stationary state in the illustrated state.

  In either case, the shutter T appears and disappears in the substantially horizontal direction, appears in the negative direction in the horizontal direction, and exits in the positive direction. The direction (movement direction) of the shutter T is shown as the operation direction AD. Further, a contact point (action point) between the game ball B and the shutter T is denoted as TP1, and a contact point between the game ball B and the wall portion W (the convex portion L in FIG. 14) is denoted as TP2 (in the case where there are a plurality, sequentially denoted as TP3, etc.). ). A virtual straight line passing through the contact point TP2 and the center o of the game ball B is defined as VL (in the case where there are a plurality of virtual straight lines, they are sequentially denoted as VL2 and the like).

Further, the static friction coefficient between the shutter T and the game ball B and the static friction coefficient between the wall portion W and the game ball B are the same, and are μ. When the mass of the game ball B is m and the acceleration of gravity is g, gravity of a size mg is acting on the game ball B vertically downward.

  FIG. 13A shows a state in which the shutter T approaches the wall portion plane of the wall portion W extending in the vertical direction and the game ball B is sandwiched between the contact points TP1 and TP2. That is, the contact TP1 and the contact TP2 are on the same straight line passing through the center o of the game ball B, and the operation direction AD and the virtual straight line VL coincide with each other.

  A straight line connecting the center o of the game ball B and the contact point TP1 coincides with the operation direction AD. At the contact TP1, a pressing force of −f1 acts on the game ball B from the shutter T in the operation direction AD. At the contact point TP2, a positive pressure (reaction force) of + f1 acts on the game ball B on the virtual straight line VL orthogonal to the wall portion W as a reaction force of the pressure force -f1.

  A vertical drag of + f1 is generated on the contact surface between the tip of the shutter T of the contact TP1 and the game ball B, and the maximum static friction force is + μf1. Further, a vertical drag of −f1 is generated on the contact surface between the wall W of the contact TP2 and the game ball B, and the maximum static friction force is + μf1.

  Accordingly, when the magnitude of gravity mg is larger than the total sum A (= 2 μf1) of the vertical component of the maximum static friction force generated at the contact TP1 and the contact TP2, that is, when 2 μf1-mg <0, Even if the sphere B is sandwiched between the wall portion W and the front end portion of the shutter T, the sphere B falls down without stopping. On the other hand, when the magnitude of gravity mg is less than or equal to the sum A, that is, when 2 μf 1 -mg ≧ 0, the game ball B is caught between the wall W and the front end of the shutter T and a ball-engaged state where the ball remains stationary is generated. Can do. Hereinafter, in this example, description will be made assuming that 2 μf1 = mg (assumed to be expression (1)).

  As described above, in the configuration shown in FIG. 13A, the shutter T when the shutter T is in contact with the game ball B and the virtual straight line VL connecting the center W of the game ball B from the contact point TP <b> 2 of the wall W and the game ball B. Therefore, the risk of biting the game ball B between the wall W and the tip of the shutter T is high. FIG. 13A shows a state in which the virtual ball VL and the operation direction AD coincide with each other through the center o of the game ball B so that the game ball B is most easily bitten, but the shutter T is somewhat parallel to the vertical direction. Even when the movement direction AD does not pass through the center o of the game ball B, the relationship between the virtual straight line VL and the movement direction AD is in a parallel state. However, in this case, the game ball B may be pushed out either above or below the shutter T with the magnitude f1 of the pressing force (closing force) that presses the game ball B of the shutter T. Or, since the total sum A of the magnitude of the maximum static frictional force in the vertical direction is smaller than when the virtual straight line VL and the operation direction AD coincide with each other, the game ball B is dropped by its own weight. May be possible.

  FIG. 13B shows a case where the wall W plane as viewed from the shutter T has a concave portion that is inclined downward toward the back. The shutter T is close to the inclined plane of the wall W at a predetermined angle with respect to the normal of the inclined plane of the wall W, and shows the state where the game ball B is sandwiched between the contact TP1 and the contact TP2.

  The operation direction AD coincides with a straight line connecting the center o of the game ball B and the contact point TP1, and passes below the contact point TP2. At the contact TP1, a pressing force of −f1 acts on the game ball B from the shutter T in the operation direction AD. Further, a vertical drag of + f1 is generated on the contact surface between the tip of the shutter T of the contact TP1 and the game ball B, and the maximum static friction force is + μf1.

  The contact TP1 and the contact TP2 are not on the same straight line passing through the center o of the game ball B, and the operation direction AD and the virtual straight line VL do not coincide with each other and are not parallel. At the contact point TP2, the game ball B is subjected to a pressing force having a magnitude fxy toward the center o of the game ball B on a virtual straight line VL orthogonal to the inclined wall surface of the wall W. It is assumed that the horizontal component force of the pressing force is + fx and the vertical component force is -fy.

  Further, a vertical drag of magnitude fxy is generated on the contact surface of the contact TP2, the maximum static frictional force directed upward in the contact surface is μfxy, the horizontal component force is + μfy, and the vertical component The force is + μfx. The sum A of the maximum static frictional forces in the vertical direction is + μf1 + μfx.

  The force acting in the horizontal direction on the game ball B is fx + μfy−f1 = 0, and the force acting in the vertical direction is μf1 + μfx−mg−fy. Accordingly, when the magnitude of the force acting vertically downward (= mg + fy) is larger than the magnitude of the friction force acting vertically upward (= μf1 + μfx), that is, when mg + fy> μf1 + μfx (formula (2)), Even if the game ball B is sandwiched between the wall portion W and the front end portion of the shutter T, the game ball B falls down without being stopped. On the other hand, in the case of μf1 + μfx ≧ mg + fy, the game ball B may be caught between the wall portion W and the front end portion of the shutter T to be stationary.

  Here, it is assumed that the configuration shown in FIG. 13A and the configuration shown in FIG. 13B have the same static friction coefficient μ and the same pressing force of the shutter T at the contact TP1 (= −f1). Since 2 μf 1> μf 1 + μfx, mg> μf 1 + μfx is satisfied using the above equation (1), and therefore mg + fy> μf 1 + μfx is satisfied, and the above equation (2) is satisfied. Therefore, if the pressing force f1 of the shutter T is the same, even when the ball engagement state occurs in the configuration shown in FIG. 13A, the configuration shown in FIG. 13B can prevent the ball engagement. There are cases where you can.

  As described above, in the configuration shown in FIG. 13B, the shutter T when the shutter T is in contact with the game ball B and the virtual straight line VL that connects the center o of the game ball B from the contact point TP2 of the wall W and the game ball B to each other. Since the operation direction AD is not parallel, the operation force of the shutter T hardly reaches the contact TP2. Therefore, the risk of biting the game ball B is reduced.

  In addition, in the case where the concave portion as shown in FIG. 13B is provided, the thinnest portion of the wall portion W needs to have a basic thickness to some extent, so that the thickness of the top portion of the wall portion W is relatively thick. Become. For this reason, it may be desirable to provide, for example, a convex portion C having a triangular cross section at the top as shown in the drawing so that the game ball B does not stay on the top of the wall W.

  FIG. 13C shows a case where the wall portion W plane has a concave portion that inclines toward the back as viewed from the shutter T and a wall portion W plane that has a convex portion that inclines toward the front side below. It is. The shutter T approaches the both inclined planes of the wall W at a predetermined angle with respect to both the concave inclined plane of the wall W and the normal of the convex inclined plane, and the contact point TP1 of the game ball B, the wall W, A state where the game ball B is sandwiched between two contact points TP2 and TP3 of the game ball B is shown. In this case, needless to explain in detail, if there is a plurality of contacts (two contacts TP2 and TP3 in this example) between the game ball B and the wall W, there is a high risk of biting the game ball B. . For this reason, it is more preferable that the wall portion W and the game ball B have one contact point.

  14A to 14D show the case where the wall W has a convex portion L that protrudes from a position above the shutter T on the wall W plane. FIG. 14A shows that the shutter T approaches the plane of the wall W in the direction normal to the plane of the wall W, and the contact between the tip TP1 of the shutter T and the corner of the convex portion L of the wall W. A state in which the game ball B is sandwiched between TP2 is shown.

  In FIG. 14A, the operation direction AD passes below the contact point TP2 and further below the center o of the game ball B. Further, the contact TP1 is on the extension of the virtual straight line VL passing through the contact TP2 and the center o of the game ball B. Therefore, the operation direction AD and the virtual straight line VL do not coincide with each other and are not parallel. An imaginary straight line VL is an x-axis (a direction from the contact TP2 toward the contact TP1 is positive), and an axis orthogonal to the x-axis is a y-axis (a direction opposite to the direction of gravitational acceleration g is positive).

  A pressing force (= −f1) is applied to the contact point TP1 of the game ball B from the front end of the shutter T in the operation direction AD. The magnitude of the vertical drag at the contact point TP1 of the game ball B is the sum f1x + mgx of the x-axis direction component force f1x of the pressing force and the x-axis direction component force mgx acting on the game ball B, and the contact point of the game ball B The maximum static frictional force in the y-axis direction at TP1 is + μ (f1x + mgx).

  On the other hand, a pressing force (= + f1) is applied to the contact point TP2 of the game ball B from the corner portion of the convex portion L in parallel with the operation direction AD. The magnitude of the vertical drag force at the contact point TP2 of the game ball B is equal to the component force f1x of the pressing force in the x-axis direction, and the magnitude of the maximum static frictional force in the y-axis direction at the contact point TP2 of the game ball B is μf1x.

  Accordingly, the force acting on the game ball B in the y-axis direction is + μ (f1x + mgx) + μf1x−mgy. Here, in order for the game ball B to fall from the state sandwiched between the contact TP1 and the contact TP2, if + μ (f1x + mgx) + μf1x−mgy <0, the game ball B surely falls. On the other hand, the maximum static frictional force + μf1x at the contact TP2 is smaller than the maximum static force + μ (f1x + mgx) at the contact TP1. Therefore, when the maximum static frictional force + μf1x at the contact point TP2 is smaller than half the y-direction component of the game ball B's own weight, the game ball B may fall with the contact point TP1 as a fulcrum.

  In FIG. 14A, if the angle formed by mg and mgy is θ, f1cosθ = f1x and mgcosθ = mgy. From the above equation (1), since μf1 = mg / 2, μf1 cos θ = (mg / 2) cos θ, and μf1x = mgy / 2 holds. Since μf1> μf1x, the game ball B can be dropped with a smaller force in the case shown in FIG. 14A than in the case shown in FIG.

  As described above, in the configuration shown in FIG. 14A, the virtual straight line VL connecting the center o of the game ball B from the contact point TP2 of the projection L of the wall W and the game ball B and the shutter T is in contact with the game ball B. Since the operation direction AD of the shutter T at the time is non-parallel, the operation force of the shutter T hardly reaches the contact TP2. Therefore, the risk of biting the game ball B is reduced. Further, there is a risk that the game ball B may be bitten by the state of the force of the movement of the shutter T in the horizontal direction depending on the shape of the game ball, but the vector itself becomes small.

  FIG. 14B shows that the shutter T approaches the plane of the wall W in the normal direction of the plane of the wall W, and the contact TP1 with the tip of the shutter T and the corner of the convex portion L of the wall W. A state in which the game ball B is sandwiched between TP2 is shown. In FIG. 14B, the operation direction AD passes below the contact point TP2 and above the center o of the game ball B. Therefore, the operation direction AD and the virtual straight line VL do not coincide with each other and are not parallel. In this state, the game ball B can be dropped downward by bringing the vertical position of the contact TP2 on the convex portion L side of the wall W and the contact TP1 on the shutter T side close to each other. The nature is decreasing.

  In FIG. 14C, the shutter T approaches the plane of the wall W in the normal direction of the plane of the wall W, the contact point TP1 of the shutter T and the game ball B, the convex portion L of the wall W, and the game A state in which the game ball B is sandwiched between the contact point TP2 of the ball B is shown. The state shown in FIG. 14C operates in substantially the same manner as the state shown in FIG. As described above, in the state shown in FIG. 14A, the virtual straight line VL connecting the center o of the game ball B from the contact point TP2 of the convex portion L of the wall W and the game ball B and the shutter T comes into contact with the game ball B. Since the operation direction AD of the shutter T at the time is non-parallel, the operation force of the shutter T hardly reaches the contact TP2. Therefore, the risk of biting the game ball B is reduced.

In FIG. 14D, the convex portion L of the wall W is the same as in FIG. 14A and the like, but the operating direction AD of the shutter T is closer to the convex portion L side than FIG. Is the case. The shutter T approaches the wall W from the normal direction of the vertical plane of the wall W, and the contact TP1 between the tip of the shutter T and the game ball B
3 shows a state in which the game ball B is sandwiched at three points: a corner portion of the convex portion L of the wall portion W, a contact point TP2 of the game ball B, and a contact point TP3 of the vertical plane of the wall portion W.

  The virtual straight line VL1 connecting the convex portion L of the wall W and the contact point TP2 of the game ball B to the center o of the game ball B and the operating direction AD of the shutter T when the shutter T contacts the game ball B at the contact point TP1 are not. It is parallel. In addition, a virtual straight line VL2 that connects the wall portion W and the contact point TP3 between the game ball B and the center o of the game ball B does not coincide with the operation direction AD but is parallel.

  In this case, since the contact point TP1 between the shutter T and the game ball B can be positioned above the center o of the game ball B, that is, above the virtual straight line VL2, the requirements such as the weight of the game ball B are included. It can be easily dropped to the lower side. In addition, what is necessary is just to make the position of the convex part L and the up-down direction of the shutter T adjoin the contact TP1 of the shutter T and the game ball B upward. Specifically, the length (distance) of the perpendicular line from the contact point TP2 of the convex part L in the operation direction AD may be shorter than the length of the perpendicular line from the contact point TP2 of the convex part L to the virtual straight line VL2.

  As described above, even when contact is made at the two contact points TP2 and TP3 on the wall W side, one contact point TP2 is at the corner of the convex portion L, and the contact point TP1 between the shutter T and the game ball B is the game ball. If it is above the center o of B, it is possible to drop the game ball B to the lower side by the force by which the shutter T operates and the gravity of the game ball B.

  Although illustration is omitted, when the protrusion amount of the convex portion L is increased, the risk of two-point contact at the wall portion W as shown in FIG. 14D can be reduced. Thus, if the convex portion L is formed so that there is only one contact on the wall W side of the game ball B in a state where the shutter T is in contact with the game ball B, the wall W side and the shutter T 3 The ball biting can be prevented by avoiding point support.

  In addition, when the protrusion amount of the convex part L is increased in order to avoid two-point contact between the wall part W and the game ball B, it is necessary to prevent the game ball B from getting on top of the convex part L. For that purpose, in the case of having the convex portion L as shown in FIGS. 14A to 14D, the upper portion of the convex portion L is, for example, a triangular cross section so that the game ball B does not stay on the upper portion of the convex portion L. It is desirable to provide the shape.

  Based on the various states described above, FIG. 14 (e) shows a convex portion L formed by a cross-sectional shape cut by a plane perpendicular to the direction parallel to the wall portion W, or an arc of an ellipse, or a combination thereof. Show. Thereby, it can avoid that the game ball B gets on the convex part L. FIG.

  Further, FIG. 14 (f) shows a convex portion L in which a cross-sectional shape cut by a plane orthogonal to the direction parallel to the wall portion W is formed in a triangular shape with the bottom side being the wall portion W side. Thereby, it is possible to avoid the game ball B from riding on the convex portion L, and it is possible to increase the possibility that the contact between the wall W and the game ball B is one point. In addition, since the convex portion L is formed above the position where the shutter T appears, when the game ball B is about to be bitten, the game ball B can be released upward.

  Next, the ball biting prevention operation using the uneven portion 900 of the shutter type winning device 700 according to the present embodiment will be described with reference to FIG. FIGS. 15A to 15C schematically show a cross section in the vicinity of the variable prize winning opening 235 cut along a plane orthogonal to the left-right direction (the direction from the back to the front of the page).

FIG. 15A shows a ball biting operation that can occur when the uneven portion 900 is not provided as a comparative example, and shows a state similar to FIG. A game ball B flowing down the game area 124 toward the opening surface of the variable winning opening 235 is a shutter protrusion / disengagement opening 72 in the base plane portion 720a.
The figure shows a ball-engaged state in which it comes into contact with the front end portion 800b of the shutter 800 on the way from 0b and comes into contact with the front surface rear surface 710b and is stationary.

  Gravity mg acts on the game ball B vertically downward. The contact point between the shutter tip part 800b and the game ball B when the shutter tip part 800b comes into contact with the game ball B is TP1, and the contact point between the front part back surface 710b side and the game ball B at the same point is TP2.

  A forward pressing force F1 (size f1) from the shutter 800 is acting on the game ball B at the contact point TP1 in the operation direction AD equal to the direction in which the shutter 800 appears. The operation direction AD coincides with a straight line connecting the center (center of gravity) o of the game ball and the contact point TP1. In addition, a reaction force Fr1 having the same magnitude f1 as the pressing force F1 and a reverse direction acts on the virtual straight line VL passing through the center of the game ball B perpendicular to the front surface back surface 710b at the contact point TP2. Yes. That is, the contact point TP1 and the contact point TP2 are on a straight line passing through the center of the game ball B, and the operation direction AD and the virtual straight line VL coincide with each other.

  In this case, a vertical drag of magnitude f1 is generated on the contact surface between the shutter tip 800b of the contact TP1 and the game ball B, and the magnitude is μf1 and is directed vertically upward when the static friction coefficient is μ. A maximum static friction force Ff1 is generated. Further, a vertical drag of size f1 is generated on the contact surface between the front surface rear surface 710b of the contact TP2 and the game ball B, and the size is μf1 when the static friction coefficient is μ (same as the contact TP1). Thus, the maximum static friction force Ff2 directed vertically upward is generated.

  Therefore, as long as the magnitude of gravity mg directed vertically downward does not exceed the sum Ff1 + Ff2 of the maximum static frictional force, the ball-engaged state in which the game ball B is sandwiched between the front surface rear surface 710b and the shutter front end portion 800B Can occur.

  FIG. 15 (b) shows a state in which the ball engagement is avoided by the concavo-convex portion 900 as the first embodiment. The concavo-convex portion 900 has a sloped portion 900b that inclines backward as it goes downward. In the state shown in FIG. 15 (b), the game ball B flowing down the game area 124 toward the opening surface of the variable winning opening 235 is in the process of being released from the shutter retracting opening 720b of the base plane portion 720a. The shutter tip 800b is in contact with the contact TP1, and the protruding lower end protruding from the front surface back surface 710b of the convex beam portion 900a of the uneven portion 900 on the front surface back surface 710b is in contact with the contact TP2. .

  In this embodiment, the operation direction AD is below the contact point TP2 and further below the center o of the game ball B, and the operation direction AD and the virtual straight line VL do not coincide with each other and are not parallel. This state is the same as the state of FIG. 14A, and further shows a state where the contact TP1 is above the intersection with the game ball B on the extension of the virtual straight line VL.

  Thus, in the first embodiment shown in FIG. 15B, when the game ball B flowing down the game area 124 contacts the shutter 800 and the front surface back surface 710b side, the front surface back surface 710b side and the game ball B The imaginary straight line VL connecting the contact point TP2 of the game ball B and the center o of the game ball B is uneven on the front surface rear surface 710b side so as to be non-parallel to the operation direction AD of the shutter 800 when contacting the game ball B in the shutter 800. The portion 900 is formed.

  According to the configuration of the present embodiment, the shutter 800 when the shutter 800 comes into contact with the game ball B and the virtual straight line VL that connects the uneven portion 900 of the front surface back surface 710b and the contact point TP2 of the game ball B to the center o of the game ball B. Since the operation direction AD is not parallel, the operation force of the shutter 800 does not easily reach the contact point TP2. Therefore, the risk of biting the game ball B is reduced.

  Specifically, in order to reduce the risk of two-point contact at the wall W as shown in FIG. 14D, the amount of protrusion of the uneven portion 900 from the front surface back surface 710b is relatively increased. ing. Thereby, the contact on the front surface rear surface 710b side of the game ball B in a state where the shutter 800 is in contact with the game ball B is only one of the contact points TP2 on the corners of the concavo-convex portion 900, and the front surface rear surface 710b side and the shutter. It is possible to prevent ball biting by avoiding three-point support at 800.

  In addition, when the protrusion amount of the convex part L is increased in order to avoid two-point contact between the wall part W and the game ball B, it is necessary to prevent the game ball B from getting on top of the convex part L. Therefore, the uneven portion 900 has a sloped portion 900b.

  FIG. 15 (c) shows a state in which the ball engagement is avoided by the uneven portion 900 as the second embodiment. The concavo-convex portion 900 has a sloped portion 900b that inclines backward as it goes downward. In the state shown in FIG. 15C, the game ball B flowing down the game area 124 toward the opening surface of the variable winning opening 235 is in the process of being released from the shutter retracting opening portion 720b of the base plane portion 720a. The shutter front end portion 800b is touched with the contact point TP1, and the front surface back surface 710b of the concave portion of the uneven portion 900 on the front surface back surface 710b is in contact with the contact point TP2.

  In this embodiment, the operation direction AD is below the projecting lower end side of the convex beam portion 900a, passes through the center o of the game ball B and the contact TP2, and the operation direction AD and the virtual straight line VL do not coincide with each other but are parallel to each other. It has become. This state is similar to the state of FIG.

  Thus, in Example 2 shown in FIG. 15C, when the game ball B flowing down the game area 124 comes into contact with the shutter 800 and the front surface back surface 710b side, the front surface back surface 710b side and the game ball B The concavo-convex portion 900 on the front surface rear surface 710b side so that the virtual straight line VL connecting the contact point TP2 of the game ball B and the center o of the game ball B does not coincide with the operation direction AD of the shutter 800 when contacting the game ball B in the shutter 800. Is formed.

According to the configuration of the present embodiment, the virtual straight line VL connecting the concave portion of the concave and convex portion 900 on the front surface back surface 710b and the center o of the game ball B from the contact point TP2 of the game ball B and the shutter 800 at the time when the shutter 800 contacts the game ball B. Since the operating direction AD of the shutter 800 does not match, the operating force of the shutter 800 does not easily reach the contact point TP2. Therefore, the risk of biting the game ball B is reduced.
According to the configuration shown in FIGS. 15B and 15C, the uneven portion 900 is formed above the position where the shutter 800 appears, so that when the game ball B is about to bite, the variable prize opening 235 is formed. It is possible to allow the game ball B to escape to the outside of the shutter-type winning device 700 from above the opening surface.

  Next, the function (part 1) of the bottom surface portion first inclined plane 710e of the variable winning opening 235 of the shutter type winning device 700 according to the present embodiment will be described with reference to FIG. FIG. 16A shows a cross section of the variable winning opening 235 cut in the vertical direction along the line BB in FIG. 12A as viewed toward the base plane portion 720a. FIG. 16B is a cross-sectional view of the variable winning opening 235 having the bottom surface portion first inclined plane 710e removed and only the bottom surface portion second inclined plane 710f in the bottom surface portion as viewed as a comparative example toward the base plane portion 720a. Is shown.

  First, in the configuration shown in FIG. 16B, the bottom surface portion first inclined plane 710e is not provided, and the bottom surface portion second inclined plane 710f is connected directly from the right wall surface of the left side surface portion 710c that is vertically cut. For this reason, if the width from the left wall surface of the right side surface portion 710d to the right wall surface of the left side surface portion 710c is, for example, a length of five game balls B, the game balls are tightly sandwiched between the left and right side wall portions, resulting in ball clogging. In such a case, it is difficult to remove the ball and eliminate clogging.

  On the other hand, in the configuration shown in FIG. 16A, the bottom surface portion first inclined plane 710e and the bottom surface portion second inclined plane 710f are continuous. For this reason, even if five game balls B are connected in the same state as shown in FIG. 16B, for example, two bottom surface portion first inclined planes 710e and bottom surface portion second inclined planes 710f having different inclination angles are formed. Since it is provided, a large space E can be created in the portion where the inclination changes even when the game ball B is clogged, so that it may be easy to take out the ball and contribute to easy elimination of the clogging. In addition, the code | symbol K shown to Fig.16 (a) is the positioning protrusion formation part to a center decoration member.

  Next, the function (No. 2) of the bottom face portion first inclined plane 710e of the variable winning opening 235 of the shutter type winning device 700 according to the present embodiment will be described with reference to FIG. The illustration of the variable winning opening 235 shown in FIG. 17A is the same as FIG. The illustration of the variable winning opening 235 shown in FIG. 17B is the same as FIG. 16B as a comparative example.

  First, in the configuration shown in FIG. 17B, when the kinetic energy of the game ball B that passes through the opening surface of the variable winning opening 235 and flies from the upper right to the lower left is sufficiently high, Directly colliding with the relatively gentle bottom surface second inclined plane 710f of the bottom surface, it bounces off at the bottom surface second inclined plane 710f and passes again through the opening surface of the variable winning opening 235, or jumps over the non-winning ball passage 710g, or There arises a problem that the non-winning ball passage 710g rolls out of the variable winning opening 235.

  On the other hand, in the configuration shown in FIG. 17A, the bottom face portion first slope plane 710e having a larger tilt angle than the bottom face portion second slope plane 710f is provided on the left side face portion 710c side. Even if the kinetic energy of the game ball B that passes through the opening surface and flies from the upper right to the lower left direction is large, the game ball B that bounces off at the bottom face first inclined plane 710e proceeds to the right side face 710d side, so the variable prize opening 235 In this case, the kinetic energy is not attenuated and does not pass through the opening surface of the variable winning opening 235 again and exit from the variable winning opening 235.

  Next, the function (No. 3) of the bottom surface portion first inclined plane 710e of the variable winning opening 235 of the shutter type winning device 700 according to the present embodiment will be described with reference to FIG. The illustration of the variable winning opening 235 shown in FIG. 18A is the same as FIG. The illustration of the variable winning opening 235 shown in FIG. 18B is the same as FIG. 16B as a comparative example.

  First, in the configuration shown in FIG. 18B, when the game ball B that passes through the opening surface of the variable prize opening 235 and flies from the upper right to the lower left direction directly collides with the right wall surface of the left side surface portion 710c that cuts up and down, Since the angle formed with the normal to the right wall surface at the time of collision is relatively large, the reflection angle is also large. For this reason, the distance which falls immediately on the bottom face second inclined plane 710f and rolls down the bottom face second inclined plane 710f becomes relatively long. As a result, the speed of the sphere decreases and the time to reach the sphere detection sensor 732 becomes relatively long, so that there may be a case where it cannot be kept within the desired number of over winnings.

  On the other hand, in the configuration shown in FIG. 18A, when a game ball B that passes through the opening surface of the variable prize opening 235 and flies from the upper right to the lower left direction directly collides with the bottom surface first inclined plane 710e, Since the angle formed with the normal line of the first inclined plane 710e of the bottom surface portion is relatively small, the reflection angle is also small. For this reason, the distance which flies over the bottom part 2nd inclination plane 710f is long, and the distance which rolls down the bottom part 2nd inclination plane 710f becomes relatively short. As a result, the ball speed does not decrease and the time to reach the ball detection sensor 732 is relatively shortened, so that it can be suppressed within the desired number of over winnings.

In addition, it is possible to quickly detect the game ball B that has won a prize at a position far from the ball detection sensor 732 by the bottom face first inclined plane 710e. Moreover, it becomes possible to prevent the ball biting in the vicinity of the bottom surface first inclined plane 710e by performing quick detection.

FIG. 19 shows a state where the shutter type winning device 700 is attached to the game board 200. The figure shows a state in which the shutter-type winning device 700 is viewed from directly above, with the front side of the shutter-type winning device 700 shown on the left side of the drawing and the left side shown on the upper side of the drawing. As shown in FIG. 19, a transparent plate member 118 is provided in front of the shutter-type winning device 700 attached to the game area 124 of the game board 200.
In general, the distance from the front surface of the game board 200 to the transparent plate member 118 is longer than one game ball. That is, if the width from the surface of the game board 200 to the front surface of the front surface portion 710a is adjusted based on the width of the game ball, there is a risk that the distance between the front surface portion 710a and the transparent plate member 118 is increased and the game ball gets on.
In contrast, the present embodiment is characterized in that the transparent plate member 118 and the front surface portion 710a are arranged close to each other. The degree of proximity of the transparent plate member 118 and the front surface portion 710a is set to a distance shorter than the radius of the game ball. Since the transparent plate member 118 and the front surface portion 710a are arranged close to each other, it is possible to prevent the game ball from being supported on the front surface portion 710a by being supported by the transparent plate member 118 and the front surface portion 710a.

Next, the characteristic configuration of the pachinko machine 100 according to the present embodiment described above will be described with reference to FIGS. 1 to 19 again.
(1) In the pachinko machine 100 according to the present embodiment, a game board (for example, the game board 200) having a game area (for example, the game area 124) and a game ball (for example, a game ball B) launched in the game area are provided. A game machine including a winning device (for example, a shutter-type winning device 700) capable of winning a prize, wherein the winning device is formed from the surface of the game board toward the front (for example, closer to the player). Side surfaces (for example, the left side surface portion 710c and the right side surface portion 710d), a front surface portion (for example, the front surface portion 710a) formed on the front surface side in connection with the side surface portions, and a space defined by the side surface portions and the front surface portion. (E.g., a space S) is provided with a movable member (e.g., a shutter 800) that can move in and out, and is configured to allow winning of the game ball by the movement of the movable member. When the game ball to be lowered comes into contact with the movable member and the back side of the front part (for example, the front part back side 710b side), the contact point between the front part back side and the game ball (for example, contact TP2) An operation direction (for example, an operation direction AD) of the movable member when a virtual line (for example, a virtual straight line VL) connecting the centers (for example, the center o) of the game ball contacts the game ball in the movable member. An uneven portion (for example, an uneven portion 900) is formed on the back surface side of the front portion so as not to coincide with.

According to the pachinko machine 100 having the above-described configuration, for example, it is possible to reduce the ball biting of a shutter opening / closing type winning device. The operating direction of the movable member is a vector oriented in the movable direction when the movable member comes into contact with the game ball, and includes a movable member in which the winning device is not only linear reciprocating but also rotatable. When both the moving direction (vector direction) when the movable member contacts the game ball and the virtual line connecting the contact point of the game ball and the front surface (uneven portion) and the center of the game ball overlap ( When they match, the game ball is most likely to be bitten. When both lines do not match but are parallel, it may be easier to bite the game ball than when they are not parallel. By making the relationship between the two lines non-parallel, the vector direction of the movable member does not face the contact direction between the concavo-convex portion and the game ball, so that it becomes more difficult to bite the ball.
In addition, it is only necessary that the predetermined two points or all two points of the plurality of contacts have the configuration of the present invention. Further, if two predetermined contact points are close to each other and are not greatly deviated in the height direction, a three-point contact may be used.

(2) The pachinko machine 100 includes a transmission member (for example, a transparent plate member 118) that can transmit the game area, and the transmission member and the front surface portion are arranged close to each other. According to the pachinko machine 100, since the transmissive member and the front surface portion are arranged close to each other, it is possible to prevent the game ball from being supported on the front surface portion and supported by the transmissive member and the front surface portion.

(3) In the pachinko machine 100, the concavo-convex portion is formed above the appearing position of the movable member. According to the pachinko machine 100, since the uneven portion is formed above the position where the movable member appears, if the game ball is about to bite, it will escape outside the winning device (wider than the winning device). Is possible.

(4) In the pachinko machine 100, the uneven portion is formed so that there is one contact point with the front portion of the game ball in a state where the movable member is in contact with the game ball. According to the pachinko machine 100, it is possible to prevent ball biting by avoiding three-point support between the concave and convex portions and the movable member.

(5) The pachinko machine 100 is characterized in that the movable member is a plate-like member (for example, the shutter flat surface portion 800a), and the distal end of the movable member is formed thin (for example, the shutter front end portion 800b). To do. According to the pachinko machine 100, since the tip of the movable member is formed thin, the possibility of ball engagement itself may be reduced by reducing the area that can be a contact point on the movable member side.

(6) In the pachinko machine 100, the movable member is configured to be able to appear and retract in the front-rear direction (for example, the front-rear direction viewed from the player). According to the pachinko machine 100, the winning device can be smoothly opened and closed.

(7) The pachinko machine 100 is characterized in that the concavo-convex portion is formed in the left-right direction of the movable member (for example, the left-right direction as viewed from the player). According to the pachinko machine 100, it is possible to prevent ball biting throughout the winning device.

(8) In the pachinko machine 100, the concavo-convex portion moves backward (for example, backward as viewed from the player) as it goes downward (for example, relatively downward as viewed toward the surface of the game board 200). And an inclined part (for example, an inclined part 900b) that is inclined. According to the pachinko machine 100, since the inclined portion is provided, the area of the top of the concavo-convex portion can be reduced so that the game ball does not get on, and the inclined portion can have one contact point with the game ball. It becomes.

(9) The pachinko machine 100 is characterized in that the interval between the uneven portion and the appearing position of the movable member is shorter than one game ball. According to the pachinko machine 100, it is possible to prevent the game ball from being sandwiched between the movable member and the uneven portion. The distance is optimally a distance of a little less than half a game ball.

(10) In the pachinko machine 100 described above, the winning device includes a bottom surface portion (for example, a bottom surface portion first inclined plane 710e, a bottom surface portion second inclined plane 710f, etc.) formed below the side surface portion and the front surface portion. In the state where the movable member appears (for example, the state where the opening surface of the variable prize opening 235 is closed (see FIG. 10A)), the winning of the game ball is restricted, while the movable member has left. It is characterized in that the game ball is allowed to win in a state (for example, a state where the opening surface of the variable winning opening 235 appears (see FIG. 10B)).

According to the pachinko machine 100, in a winning device in which the winning area (opening surface of the variable winning opening) is exposed to the gaming area, the winning area is determined by biting the ball when the movable member appears (closed). It is possible to prevent opening. During the round, the movable member opens in the next round and is naturally eliminated, but it is necessary to avoid the occurrence of ball biting in the final round of the big hit. In addition, even in the case where the movable member has a bottom surface portion and allows a winning of a game ball when it appears, when the movable member appears, the front end portion of the movable member and the back side of the front portion When the game ball is bitten, the game ball does not win in a winning-permitted state, but the uneven portion is effective to prevent this.

(11) In the pachinko machine 100, the bottom surface portion includes a bottom surface inclined portion that is inclined in the left-right direction, and the bottom surface inclined portion is a first bottom surface inclined portion having a first inclination angle (for example, a bottom surface portion first inclined plane). 710e) and a second bottom surface inclined portion (for example, a bottom surface second inclined plane 710f) that is continuous downstream of the first bottom surface inclined portion and has a smaller inclination angle than the first bottom surface inclined portion. A game ball detection means (for example, a ball detection sensor 732) for detecting the game ball is disposed on the downstream side of the second bottom inclined portion.

  According to the pachinko machine 100, it is possible to quickly detect a game ball won in a position far from the game ball detecting means by the first bottom inclined portion. In addition, it is possible to prevent the ball biting in the vicinity of the first bottom inclined portion by performing quick detection. In addition, in a winning device that does not include the first bottom inclined portion, it is conceivable that the gaming balls are exactly sandwiched between the left and right side wall portions as one form in which the gaming balls are packed in the winning space. However, in the configuration of the present invention, by providing two bottom inclined portions having different inclination angles, even when a game ball is clogged, it is possible to create a lot of space in a portion where the inclination changes, so that it is easy to clog the ball. It may contribute to resolution.

(12) In the pachinko machine 100, a first abutting portion (for example, contactable with the game ball such that the width (or region) where the game ball can roll on the downstream side of the bottom inclined portion is narrowed) A sphere alignment first member 910) is formed on the back side of the front portion. According to the pachinko machine 100, it is possible to align the game balls toward the game ball detection means.

(13) In the pachinko machine 100, the first contact portion is formed so that a plate-like portion parallel to the second bottom surface inclined portion protrudes from the back surface side of the front surface portion to be smaller than half of the game balls. It is characterized by. According to the pachinko machine 100, the game ball does not get on the plate-like portion because the plate-like portion has a projection amount smaller than 1/2 of the game balls. In addition, it is possible to reduce side friction caused by rolling of the game ball.

(14) The pachinko machine 100 includes a second contact portion (for example, a ball alignment second member 920) that protrudes upward from the first contact portion. According to the pachinko machine 100, it is possible to eliminate the fact that the game ball is placed above the first contact portion due to the winning of the game ball from the upper side of the first contact portion.

(15) In the pachinko machine 100 described above, the first contact portion is formed continuously from the upper side of the first bottom inclined portion to the side surface portion on the downstream side, and the second contact portion is connected to the downstream side. It is characterized in that it is formed to project from the side surface portion on the side at a position that is shorter than a half of the game balls. According to the pachinko machine 100, it may be possible to prevent the game ball from getting between the side surface portion and the second contact portion.

As described above, conventionally, as a general configuration of the gaming table, a winning device capable of winning a game ball when a specific determination result is derived is provided. The shutter-type winning device 700 of this example is a right-handed attacker, and allows the winning of a game ball that has flowed from the upper right to the lower left of the shutter-type winning device 700, and the bottom portion is inclined downward to the lower right. ing. On the other hand, the shutter 800 is inclined in the lower left direction in the same manner as the flow direction of the game ball, and when the shutter 800 appears, the game ball is dropped along the inclination of the upper surface of the shutter 800. And when the shutter 800 retreats and a game ball wins, it is configured to change the direction to the right downward slope and go to the ball detection sensor 732. ADVANTAGE OF THE INVENTION According to this invention, the game stand provided with the winning device which can prevent the ball biting and ball clogging by the opening / closing operation | movement of a winning device can be provided. Also, a right-handed attacker is generally intended to increase the digestion speed of a big hit, but in this embodiment, the right-handed striker eliminates a useless ball (a game ball that does not win the attacker), and a ball detection sensor. The possibility of over winning using the arrival time up to 732 is increased, and the structure is such that the interest of the player can be enhanced.

The present invention is not limited to the above embodiment, and various modifications can be made.
For example, the shape of the uneven portion 900 is not particularly limited. If there is a part that protrudes partly, the other part is a relatively recessed part, so that it can be interpreted that the uneven part 900 is formed unless the front part back surface 710b side is flat. And the uneven | corrugated | grooved part 900 may be a shape which protrudes (circle), (triangle | delta), and □, or the shape curved intricately. Among these, a particularly preferable shape is preferably one having a relatively small area of the upper portion so that the game ball does not get on the upper portion of the protruding portion. And considering that the protrusion amount of the extent which can avoid a two-point contact is required in an uneven part, it is preferable that it is an uneven part including the structure which inclines back as it goes below like the said embodiment.

  Further, for example, the front surface back surface 710b and / or the base flat surface portion 720a in the variable prize opening 235 may be inclined instead of the bottom surface inclined plane.

  Further, for example, the shutter-type winning device 700 of the present embodiment can be applied not only to the variable winning port 235 but also to all winning devices such as the variable winning port 234 and the special figure 2 starting port 226.

  Note that the items described in the above detailed description, in particular, the items described in the examples and the modifications can be combined.
