<Removal structure of operation unit 10>
Since the operation unit 10 includes a chance button 10a and the like and is operated by the player, maintenance is required by use. For this reason, in this embodiment, the operation unit 10 is configured to be detachable.

  The attachment / detachment structure of the operation unit 10 and the removal restriction structure will be described with reference to FIGS. 1 and 3 to 5. FIG. 3 is an exploded perspective view of the door 5 with a ball storage tray, and particularly shows the base 5c, the operation unit 10, and the regulating device 11. FIGS. 4A and 4B are explanatory views showing the restriction operation and restriction release operation of the restriction device 11. FIGS. 5A and 5B are explanatory diagrams of the release operation blocking unit 13.

  Referring to FIG. 3, base 5 c has an opening 5 d in the front side of door 5 with a ball storage tray. The regulating device 11 is fixed to the base portion 5c in the use state, and a part thereof is covered with the cover member 12 as shown in FIG. As shown in FIG. 3, the restriction device 11 includes a base 11a and an opening 11b formed in the base 11a. The opening 11b has a shape that approximates the opening 5d, and the peripheral portion of the opening 11b in the base 11a is fitted into the inner edge of the opening 5d. The operation unit 10 has a lid shape as a whole and is attached to the opening 11b. When the operation unit 10 is attached, the opening 11b (that is, the opening 5d) is closed. The operation unit 10 closes the opening 11b (opening 5d), so that foreign substances such as cheating instruments are not inserted from the outside through the opening 11b (opening 5d).

  The restriction device 11 includes a lever-like operation portion 11c that is rotatably supported by the base portion 11a, a claw portion 11d provided in the operation portion 11c, and a rib portion 11e. The operation unit 10 has a concave portion 10d and a claw portion 10e. The claw portion 10e is locked to the periphery of the opening portion 11b, and the concave portion 10d is attached to the opening portion 11b by engaging with the claw portion 11d. Is done. When the claw part 11d is displaced by the rotation of the operation part 11c, the removal of the operation unit 10 is restricted and released.

  FIG. 4 is a perspective view of the operation unit 10 and the restriction device 11 as viewed from below. FIG. 4A shows the restriction release state, and the restriction release state is established by rotating the operation portion 11c in the direction of the arrow in FIG. In this state, the claw portion 11d is not engaged with the concave portion 10d, so that the operation unit 10 can be removed. Further, by rotating the operation portion 11c in the direction of the arrow in the figure, the rib portion 11e is displaced in the direction approaching the opening portion 11b, and presses the operation unit 10 upward. For this reason, not only the restriction is released by the rotation of the operation portion 11c but also the operation unit 10 can be detached upward from the opening portion 11b to facilitate removal.

  FIG. 4B shows a restricted state, and the restricted state is achieved by rotating the operation portion 11c in the direction of the arrow in FIG. Specifically, the claw portion 10e of the operation unit 10 is inserted in advance under the periphery of the opening portion 11b, and the claw portion 11d is engaged with the recess 10d by rotating the operation portion 11c in the direction of the arrow in FIG. The removal of the operation unit 10 from the opening 11b is restricted by the engagement of these two places. Since the restriction and release can be performed by operating the operation unit 11c, the operation unit 10 can be easily attached and detached. In the present embodiment, the regulation and the releasing operation are the rotation of the operation unit 11c. However, the operation unit 11c may be rotated instead of being rotated.

  As shown in FIG. 1, in the use state (the state after assembly) of the door 5 with a ball storage tray, only the tip of the operation unit 11 c of the regulating device 11 protrudes from the hole 12 a of the cover member 12, and maintenance is performed. An operator touches this protruding part and performs the rotation operation of the operation part 11c.

  As shown in FIG. 1, the operation of the operation unit 11 c can basically be performed only when the door 5 with a ball storage tray is opened. However, even when locked in the closed state, an illegal act of operating the operation unit 11c through a wire or the like from the gap of the pachinko machine 1 and removing the operation unit 10 is also assumed. Therefore, in the present embodiment, the release operation blocking unit 13 is provided to block the restriction release operation of the operation unit 11c in a state where the door 5 with the ball storage tray is opened.

  In the case of the present embodiment, the release operation blocking portion 13 is a hole provided in the rail cover 9. When the door 5 with a ball storage tray is in a closed state, the distal end of the operation unit 11c enters the release operation blocking unit 13, so that the movement of the operation unit 11c is restricted by the peripheral wall. As a result, when the door 5 with a ball storage tray is in a closed state, the restriction release operation of the operation unit 11c can be prevented.

  FIGS. 5A and 5B show the relationship between the position of the operation unit 11 c and the release operation blocking unit 13. FIG. 5A shows a case where the operation unit 11c is rotated to the restriction release position. In this case, the operation part 11c is located at the left end of the hole 12a of the cover member 12 in the same figure. In the case of this embodiment, if it is going to close the door 5 with a ball storage tray as it is, the front-end | tip of the operation part 11c will not enter into the cancellation | release operation | movement prevention part 13, but will interfere with the rail cover 9, as shown with a broken line.

  As a result, the operation part 11c and the rail cover 9 obstruct the closing of the door 5 with the ball storage tray, and the operator can be aware that the operation part 11c is not located at the restriction position. In the present embodiment, the operation unit 11c that performs the regulation and release operation is used as a configuration that interferes with the rail cover 9 of the main body unit 3. However, the movable unit that is displaced in conjunction with the regulation and release operation of the regulation device 11 is used. Any configuration other than the operation unit 11c may be used as long as it is a mechanism (for example, a non-collision state at the time of regulation and a projection state at the time of release). However, a simple configuration can be achieved by providing both the functions of restriction and release operation and interference by the operation unit 11c.

  FIG. 5B shows a case where the operation unit 11c is rotated to the release position. In this case, the operation part 11c is located in the right end of the hole 12a of the cover member 12 in the same figure. In the case of the present embodiment, if the door 5 with the ball storage tray is closed as it is, the tip of the operation unit 11c enters the release operation blocking unit 13 as indicated by a broken line. Since the movement range of the operation unit 11c is restrained by the release operation blocking unit 13, the restriction release operation can be blocked.

  Thus, in the present embodiment, unauthorized removal can be prevented while maintaining the ease of attaching and detaching the operation unit 10. Moreover, since the blocking of the releasing operation by the releasing operation blocking unit 13 depends on the open / closed state of the door 5 with the ball storage tray, it is easy for a regular worker with a key to remove, but by an unauthorized person without a key. Removal can be prevented. In addition, there is an advantage that the restriction of the operation unit 10 is not released by the restriction device 11 only by opening it while preventing the restriction release operation by closing the door 5 with the ball storage tray.

  In this embodiment, the release operation unit 13 is a hole. However, any structure may be used as long as the movement range of the operation unit 11c can be restricted. In addition, although the release operation unit 13 is formed using the rail cover 9, a dedicated member can be provided in the main body unit 3. However, the number of parts can be reduced by using the parts in this way.

<Modification>
When the operator operates the operation part 11c from the restriction release position to the restriction position, if the operation amount is insufficient, it is preferable that the operation part 11c is automatically guided to the restriction position. Therefore, when the door 5 with the ball storage tray in the open state is rotated to the closed state while the operation unit 11c is in the middle position between the restriction position and the release position, the operation unit 11c is biased by the rotation. You may provide the main-body part 3 with the guide part which guides to a control position.

  FIG. 6A is a diagram illustrating an example of the guide portion 13a on the rail cover 9, and FIG. 6B is an explanatory diagram of the function of the guide portion 13a. The guide portion 13 a is a groove whose depth increases toward the release operation prevention portion 13, and guides the operation portion 11 c to the release operation prevention portion 13 by the inclined bottom portion. As a result, the operation part 11c is caused to turn and is automatically guided to the restriction position.

  FIG.6 (b) shows the relationship between the release operation | movement prevention part 13 and the guide part 13a at the time of closing the door 5 with a ball storage tray, and the position of the operation part 11c. When the operation unit 11c is in the restriction position indicated by the position P1, the operation unit 11 enters the release operation blocking unit 13 as described with reference to FIG. When the operation unit 11c is at the release position indicated by the position P3, the operation unit 11 does not enter the release operation prevention unit 13 as described with reference to FIG. It obstructs the closing of the door 5 with a dish.

  When the operation unit 11 is located at a position P2 between the position P1 and the position P3, the tip of the operation unit 11 comes into contact with the bottom of the guide unit 13a, and the bottom of the bottom with the ball storage tray door 5 is closed. Guided by the inclination, the operation unit 11 rotates and enters the release operation blocking unit 13. Thus, the operation unit 11c can be automatically guided to the restriction position, and the case where the restriction on the removal of the operation unit 10 becomes insufficient can be avoided.

<Reference example>
In the above-described embodiment, the restriction release operation is prevented by using the rotation of the door body. However, the removal of the component itself can also be controlled by using the rotation of the door body. FIG. 12 is a perspective view of the back side of the pachinko machine 1 showing a removal restricting structure as a reference example. In the example of the figure, a regulating member 14 is provided on the outer frame 2. The regulating member 14 regulates the removal of the cover member 15 that covers the power switch SW1 and the reset switch SW mounted on the main body 3. The cover member 15 cannot be removed unless it is displaced to the regulating member 14 side, and the regulating member 14 faces the cover member 15 in the state of FIG. . The cover member 15 can be removed by rotating the main body 3 relative to the outer frame 2 so that the cover member 15 and the regulating member 14 do not face each other.

<Control unit>
Next, the circuit configuration of the control unit of the pachinko machine 1 will be described in detail with reference to FIG. This figure shows a circuit block diagram of the control unit.

  The control unit of the pachinko machine 1 is roughly divided into a main control unit 30 that controls the central part of the game, and a command signal (hereinafter simply referred to as “command”) transmitted by the main control unit 30. A sub-control unit 40 that controls the display, a display control unit 50 that performs display control of the decorative symbol display device 21 based on a command transmitted from the sub-control unit 40, and a main control unit 30 according to a command transmitted by the main control unit 30. The payout control unit 61 controls the game ball payout, the launch control unit 65 controls the game ball launch, and the power management unit 51 controls the power supplied to the pachinko machine 1. .

<Type of design>
Next, using FIGS. 8A to 8C, the first special symbol display device 22b, the second special symbol display device 22c, the decorative symbol display device 21, and the normal symbol display device 22a of the pachinko machine 1 are stopped and displayed. The types of special maps and general maps to be described will be described. Fig.8 (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 opening sensor detects that the ball has entered the first special figure start opening 26c, and the ball has entered the second special figure start opening 26d. The special figure 2 variable game is started on the condition that the second start port sensor has detected.

  When the special figure 1 variable game is started, the first special symbol display device 22b performs “variable display of special figure 1” by repeating all lighting of the seven segments and lighting of the central one segment. In addition, when the special figure 2 variable game is started, the second special symbol display device 22c performs the "variable display of special figure 2" which repeats the lighting of all the seven segments and the lighting of the central one segment. Do. These “variation display of special figure 1” and “variation display of special figure 2” correspond to an example of the symbol fluctuation display according to the present invention. Then, when the variation time determined before the start of the fluctuation of the special figure 1 elapses, the first special symbol display device 22b stops and displays the stop symbol form of the special figure 1, and the fluctuation time determined before the start of the fluctuation of the special figure 2 When elapses, the second special symbol display device 22c stops and displays the stop symbol mode of the special symbol 2.

  Therefore, from the start of “figure display of special figure 1” until the stop symbol form of special figure 1 is stopped, or after the start of “fluctuation display of special figure 2”, the stop symbol form of special figure 2 is displayed. Until stop display corresponds to symbol change stop display, a series of displays from the start of this “special view 1 or 2 change display” until stop display of the special view 1 or 2 is displayed. This is called symbol variation stop display. The symbol variation stop display may be continuously performed a plurality of times.

  FIG. 8A 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. 8A, the white portions in the figure indicate the segment locations where the light is extinguished, and the black portions indicate the location where the segments are illuminated.

  “Special Figure A” is a 15 round (15R) special jackpot symbol, and “Special Figure B” is a 15R jackpot symbol. In the pachinko machine 1 of the present embodiment, whether or not a big hit in the special figure variable game is determined by lottery of hardware random numbers, and whether or not a special big hit is determined by lottery of software random numbers. The difference between the jackpot and the special jackpot is the difference in whether the probability of winning the jackpot is high (special jackpot) or low (jackpot) in the next special figure variation game. Hereinafter, a state having a high probability of winning the jackpot is referred to as a special figure high probability state, and a state having a low probability is referred to as a special figure low probability state.

  Moreover, after the 15R special jackpot game ends and after the 15R jackpot game ends, both shift to the time-saving state. Although the time reduction will be described in detail later, the state that shifts to the time reduction state is referred to as a normal high probability state, and the state that does not shift to the time reduction state is referred to as a normal low probability state. “Special figure A”, which is a 15R special jackpot symbol, is a special figure high probability normal figure high probability state, and “Special figure B”, which is a 15R jackpot symbol, is a special figure low probability ordinary figure high probability state. These “special chart A” and “special chart B” are symbols that give a relatively large profit amount to the player.

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

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

  "Special figure G" is a first small hit symbol, and "Special figure H" is a second small hit symbol, both of which are in a special figure low probability normal figure low probability state. The small hit here is equivalent to the same short hit big hit with 2R. That is, “Special Figure G” and “Special Figure H” are in the same state as “Special Figure F”, but the effects displayed on the decorative symbol display device 21 are different from each other. By providing “G”, “Special Figure H”, and “Special Figure F”, the interest of the game is enhanced.

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

  In the pachinko machine 1 according to the present embodiment, symbols other than “Special Illustration A” are also prepared as 15R special jackpot symbols, and the same applies to other symbols such as 15R jackpot symbols.

  FIG. 8B shows an example of a decorative design. There are 10 types of decoration patterns of the present embodiment: “Decoration 1” to “Decoration 10”. The first start port sensor detects that a ball has won the first special figure start port 26c or the second special view start port 26d, that is, the ball has entered the first special view start port 26c, or On the condition that the second start port sensor detects that a ball has entered the second special symbol start port 26d, the left symbol display area RL, the middle symbol display area RC, and the right symbol display of the decorative symbol display device 21. Displayed in the order of “decoration 1” → “decoration 2” → “decoration 3” →... “Decoration 9” → “decoration 10” → “decoration 1” →... “Decoration display of decorative pattern” is performed.

  When notifying the 15R jackpot of “Special Figure B”, the symbol combination in which three same decorative symbols corresponding to the 15R jackpot are arranged in the symbol display areas RL, RC, RR (for example, “decoration 1-decoration 1”). -"Decoration 1", "Decoration 2-Decoration 2-Decoration 2", etc.) are stopped and displayed. When notifying 15R special jackpot of “special drawing A”, a combination of three symbols of the same odd number of decorative symbols (for example, “decoration 3—decoration 3—decoration 3” or “decoration 7—decoration 7—decoration 7”). Etc.) is stopped and displayed.

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

  On the other hand, when notifying the first deviation of “Special Figure I” and the second deviation of “Special Figure J”, symbol combinations other than the symbol combinations shown in FIG. 8B are displayed in the symbol display areas RL, RC, and RR. To stop display.

  FIG. 8 (c) shows an example of a usual stop display symbol. In the present embodiment, there are two types of stoppage display modes for ordinary maps: “general diagram A” which is a winning symbol and “general symbol B” which is a missed symbol. Based on the fact that the above-mentioned gate sensor has detected that the sphere has passed through the general opening 26b, the normal symbol display device 22a repeats all lighting of the seven segments and lighting of the central one segment. Perform a “normal change display”. Then, when notifying the winning of the common figure variable game, the “normal figure A” is stopped and displayed, and when notifying the usual figure variable game, the “normal figure B” is stopped and displayed. Also in FIG. 5C, the white portions in the drawing indicate the locations of the segments that are turned off, and the black portions indicate the locations of the segments that are turned on.

<Main control unit main processing>
Next, main control unit main processing executed by the CPU 31a of the main control unit 30 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 30 is provided with the start signal output circuit (reset signal output circuit) 32a that outputs the start signal (reset signal) when the power is turned on. The CPU 31a of the basic circuit 31 to which this activation signal has been input performs a main control section main process shown in FIG. 9 in accordance with a control program stored in advance in the ROM 31b after being reset by a reset interrupt.

  In S1, initial setting 1 is performed. In this initial setting 1, setting of a stack initial value (temporary setting) to the stack pointer (SP) of the CPU 31a, setting of an interrupt mask, initial setting of an I / O 31d, initial setting of various variables stored in the RAM 31c, to the WDT 31f The operation is permitted and the initial value is set. In the present embodiment, a numerical value corresponding to 32.8 ms is set in the WDT 31f as an initial value.

  In S2, the value of the counter of WDT 31f is cleared, and the time measurement by WDT 31f is restarted. In S3, whether or not the low voltage signal is on, that is, the voltage value of the power supply that the voltage monitoring circuit 33g supplies from the power management unit 51 to the main control unit 30 is a predetermined value (9v in this embodiment). ), It is monitored whether or not a low voltage signal indicating that the voltage has dropped is output. Then, when the low voltage signal is on (when the CPU 31a detects that the power supply is cut off), the process returns to S2. When the low voltage signal is off (when the CPU 31a does not detect that the power supply is cut off), the process returns to S4. move on. Even if the predetermined value (9 V) is not yet reached immediately after the power is turned on, the process returns to S2, and S3 is repeatedly executed until the supply voltage becomes equal to or higher than the predetermined value.

  In S4, initial setting 2 is performed. In this initial setting 2, a process for setting a numerical value for determining a cycle for executing a main control unit timer interrupt process, which will be described later, to the counter timer 31e, a predetermined port of the I / O 31d (for example, a test output port, A process of outputting a clear signal from the output port to the sub control unit 40, a setting for permitting writing to the RAM 31c, and the like are performed.

  In S5, it is determined whether or not to return to the state before power interruption (before power interruption), and the state before power interruption is not restored (when the basic circuit 31 of the main control unit 30 is set to the initial state). Then, the process proceeds to the initialization process (S7). Specifically, whether or not a RAM clear signal transmitted when a RAM clerk or the like of a game store first operates a RAM clear switch provided on the power supply board is on (indicating 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 S7 to set the basic circuit 31 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 31c 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 S7 to set the basic circuit 31 to the initial state. If the power status information is information indicating suspend, a predetermined area (in the RAM 31c ( For example, a checksum is calculated by adding all 1-byte data stored in 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 the checksum result is normal).

  If the checksum result is a specific value (for example, 0) (if the checksum result is normal), the process proceeds to SA11 to return to the state before the power interruption, and the checksum result is a specific value. If it is other than (for example, 0) (if the result of the checksum is abnormal), the process proceeds to S7 to set the pachinko machine 1 to the initial state. Similarly, if the power status information indicates information other than “suspend”, the process proceeds to S7.

  In S6, a power recovery process is performed. In this power recovery process, the value of the stack pointer stored in the stack pointer save area provided in the RAM 31c at the time of power failure is read 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 31c 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 31a executing the control program based on the stack pointer and registers after resetting, the pachinko machine 1 returns to the state when the power is turned off.

  That is, the processing is restarted from the instruction next to the instruction (predetermined in S8 and S9) performed immediately before branching to the timer interrupt processing (described later) immediately before the power interruption. The RAM 31c mounted on the basic circuit 31 in the main control unit 30 is provided with a transmission information storage area. In S6, 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 sub-control unit 40 in S27 in the timer interrupt process of the main control unit 30, which will be described later.

  In S7, an initialization process 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 31c, and the like are performed. Further, here, a normal return command is set in a transmission information storage area provided in the RAM 31c of the main control unit 30. This normal return command is a command indicating that the initialization process (S7) of the main control unit 30 has been performed, and in the same way as the power recovery command, in step S27 in the timer interrupt process of the main control unit 30, the sub control unit 40.

  In S8, after setting for prohibition of interruption, a basic random number initial value update process is performed. In this basic random number initial value update process, two initial value generation random number counters for generating the initial values of the ordinary figure winning random number counter and the special figure random value counter, the ordinary figure timer random number value, and the special figure timer, respectively. Two random number counters for generating each random number value are updated. For example, assuming that the range of values that can be taken as normal timer random number values is 0 to 20, a value is acquired from a random number counter storage area for generating a normal timer random number value provided in the RAM 31c, and 1 is added to the acquired value. Then, it is stored in the original random number counter storage area. At this time, if the result of adding 1 to the acquired value is 21, 0 is stored in the original random number counter storage area. Other initial value generation random number counters and random number counters are similarly updated. Further, after this basic random number initial value updating process is completed, an interrupt permission is set and the process proceeds to S9.

  In S9, effect random number update processing is performed. In this effect random number update process, a random number counter for generating an effect random value used in the main control unit 30 is updated. In the RAM 31c of the main control unit 30, a first special figure notice lottery random number counter for generating a first special figure notice lottery random number value that can take a value in the range of 0 to 127, and a value in the range of 0 to 127 are also obtained. A second special figure notice lottery random number counter for generating a second special figure notice lottery random number value to be obtained is provided. In SA17, the values of these counters are updated.

  The main control unit 30 repeatedly executes the processes of S8 and S9 except during the timer interrupt process that starts every predetermined period.

<Main control unit timer interrupt processing>
Next, the main control unit timer interrupt process executed by the CPU 31a of the main control unit 30 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 30 includes a counter timer 31e that generates a timer interrupt signal at a predetermined cycle (in this embodiment, about once every 2 ms). The main control unit timer interrupt is triggered by this timer interrupt signal. The process is started at a predetermined cycle.

  In S11, a timer interrupt start process is performed. In this timer interrupt start process, a process of temporarily saving the value of each register of the CPU 31a to the stack area is performed. In S12, the WDT 31f count value exceeds the initial setting value (32.8 ms in the present embodiment), so that WDT interruption does not occur (so as not to detect a processing abnormality), the WDT is periodically performed (this implementation). In the embodiment, restart is performed once every about 2 ms, which is the period of the main control unit timer interrupt.

  In S13, an input port state update process is performed. In this input port state update process, the detection signals of the various sensors 35a are input via the input port of the I / O 31d to monitor the presence or absence of the detection signals, and the signal states provided for each of the various sensors 35a in the RAM 31c. Store in the storage area. 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 31c for each sphere detection sensor. This information is read out from the previous detection signal storage area partitioned and stored in the RAM 31c 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 31c, and this information is read out from the previous detection signal storage area described above. To remember. Further, the detection signal of each sphere detection sensor detected this time is stored in the above-described current detection signal storage area.

  In S13, the information on the presence / absence of the detection signal of each sphere detection sensor stored in each storage area of the detection signal storage area, the previous detection signal storage area, and the current detection signal storage area is compared. It is determined whether or not the information on the presence or absence of detection signals for the past three times in the ball detection sensor matches the winning determination pattern information. This main control unit timer interrupt process that is repeatedly started at a very short interval of about 2 ms while one game ball passes one ball detection sensor is started several times. For this reason, every time the main control unit timer interrupt process is activated, in S13 described above, a detection signal indicating that the same game ball has passed the same ball detection sensor is confirmed.

  As a result, a detection signal indicating that the same game ball has passed the same ball detection sensor is stored in each of the detection signal storage area, the previous detection signal storage area, and the current detection signal storage area. That is, when the game ball starts to pass through the ball detection sensor, there is no detection signal before, a previous detection signal, and a current detection signal. In the present embodiment, in consideration of erroneous detection of the sphere detection sensor and noise, it is determined that there is a prize when the detection signal is stored twice continuously after no detection signal.

  The ROM 31b of the main control unit 30 stores winning determination pattern information (in this embodiment, information indicating that there is no previous detection signal, that there is a previous detection signal, and that there is a current detection signal). In this S13, the information on the presence or absence of detection signals for the past three times in each sphere detection sensor is pre-determined winning determination pattern information (in this embodiment, no previous detection signal, previous detection signal, current detection signal present). If it matches the information), the general winning opening 26a, the variable start opening 26e, the first special figure start opening 26c, the second special figure start opening 26d, or the general start start opening 26b. It is determined that there was a passage.

  That is, it is determined that there has been a prize at these start ports. 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 that detects the winning at the general winning opening 26a, there is a winning at the general winning opening 26a. If the information on the presence / absence of detection signals for the past three times does not match the above-mentioned winning determination pattern information, the subsequent general winning is performed. The process branches to the subsequent process without performing the process associated with winning a prize in the mouth 26a.

  The ROM 31b of the main control unit 30 stores winning determination clear pattern information (in the present embodiment, information indicating that there is a detection signal before, 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 S14 and S15, basic random number initial value update processing and basic random number update processing are performed. In these basic random number initial value update processing and basic random number update processing, the value of the initial value generation random number counter performed in S8 is updated, and then, the normal winning random number value used in the main control unit 30 is displayed. The two random number counters for generating the random number value in FIG. 1 and the special figure 2 random value are updated.

  For example, assuming that the range of values that can be taken as the winning random number value is 0-100, the value is acquired from the random number counter storage area for generating the winning random number value provided in the RAM 31c, and 1 is added to the acquired value. Then, it is stored in the original random number counter storage area. At this time, if the result of adding 1 to the acquired value is 101, 0 is stored in the original random number counter storage area. If it is determined that the random number counter has made one round as a result of adding 1 to the acquired value, the value of the initial value generating random number counter corresponding to each random number counter is acquired and stored in the storage area of the random number counter. set.

  For example, a value is acquired from a random number counter for generating a random number for random selection in a numerical value range of 0 to 100, and a result obtained by adding 1 to the acquired value is stored in a predetermined initial value storage area provided in the RAM 31c. If the value is equal to the previously set initial value (for example, 7), the value is acquired as an initial value from the initial value generation random number counter corresponding to the random number counter for generating the random number for winning the normal number, The initial value set this time is stored in the above-described initial value storage area in order to determine that the random number counter for generating the winning random number value has made one round next time, in addition to setting it in the random number counter for generating the winning random value Keep it.

  Further, apart from the above-described initial value storage area for determining that the random number counter for generating the random number for winning the normal signal has made one round next, it is determined that the random number counter for generating the special figure random number has made one round. An initial value storage area is provided in the RAM 31c. In the present embodiment, the counter for acquiring the random number value of FIG. 1 and the counter for acquiring the random value of FIG. 2 are separately provided, but the same counter may be used.

  In S16, effect random number update processing is performed. In this effect random number update process, a random number counter for generating an effect random value used in the main control unit 30 is updated. Here, the random number counter for generating the random number for production performed in S9 is updated. Accordingly, the values of the special figure 1 notice lottery random number counter and the special figure 2 notice lottery random number counter are updated in S16.

  In S17, timer update processing is performed. In this timer update processing, the normal symbol display symbol update timer for timing the time for changing / stopping the symbol display on the normal symbol display device 22a, and the time for changing / stopping the symbol display on the first special symbol display device 22b are counted. Special symbol 1 display symbol update timer for performing, special symbol 2 display symbol update timer for measuring the time for changing / stopping the symbol display on the second special symbol display device 22c, predetermined winning effect time, predetermined opening time Various timers including a timer for measuring a predetermined closing time, a predetermined end effect period, and the like are updated.

  In S18, a winning opening counter update process is performed. In this winning opening counter updating process, when there is a winning at the starting opening or winning opening, the value of the winning ball number storage area provided for each winning opening or for each starting opening is read into the RAM 31c and 1 is added. To the original prize ball number storage area. In S19, a winning acceptance process is performed.

  In S20, a payout request number transmission process is performed. The output schedule information and the payout request information output to the payout control unit 61 are composed of 1 byte, strobe information in bit 7 (indicating that data is set when on), and power supply in bit 6 Input information (indicating that it is the first command transmission after power-on when turned on), bits 4-5 for the current processing type for encryption (0-3), and bits 0-3 for encryption processing The number of subsequent payout requests is indicated.

  In S21, a normal state update process is performed. This normal state update process performs one of a plurality of processes corresponding to the normal state. For example, in the normal state update process during the normal symbol change display (the above-described general symbol display symbol update timer value is 1 or more), the 7-segment LED constituting the normal symbol display device 22a is repeatedly turned on and off. Turns off drive control. By performing this control, the normal symbol display device 22a performs normal fluctuation display (normal figure fluctuation game).

  Also, in the normal state update process at the timing when the normal symbol change display time has elapsed (the timing when the value of the general symbol display symbol update timer has changed from 1 to 0), if the hit flag is on, the win symbol is displayed. The normal symbol display device 22a is controlled to be turned on and off so that the normal symbol display device 22a is turned on. 7 segment LED on / off drive control is performed.

  The RAM 31c of the main control unit 30 is provided with a setting area for performing various settings in various processes, not limited to the normal state update process. Here, the above-described lighting / extinguishing drive control is performed, and the setting area is set to indicate that the normal stop display is being performed. By performing this control, the normal symbol display device 22a determines the symbol of either the winning symbol (the common symbol A shown in FIG. 8C) or the off symbol (the universal symbol B shown in FIG. 8C). Display. Thereafter, information indicating the stop period is set in a storage area of a normal stop time management timer provided in the RAM 31c in order to maintain the display for a predetermined stop display period (for example, 500 milliseconds). 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. In the case where 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 value of the usual figure stop time management timer is changed from 1 to 0), A signal for holding the blade member in an open state is sent to the solenoid for driving opening and closing of the blade member of the second special figure starting port 26d for a predetermined opening period (for example, 2 seconds) while setting the normal operation in the setting area. In addition to outputting, information indicating the open period is set in the storage area of the blade open time management timer provided in the RAM 31c. As described above, when the result of the normal figure variable game is a win, the game state shifts to a game state having a high advantage for the player in that the game ball can easily enter the second special figure starting port 26d.

  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 open / close driving solenoid, and information indicating the closing period is set in the storage area of the blade closing time management timer provided in the RAM 31c.

  Further, in the normal state update process that starts at the timing when the predetermined closing period ends (the timing when the value of the blade closing time management timer changes from 1 to 0), the non-operating state is set in the setting area of the RAM 31c. To do. Furthermore, if the result of the usual figure fluctuation game is out, the usual figure out flag is turned on as will be described later. When the off-normal flag is on, the normal state update process at the timing when the predetermined stop display period described above ends (the timing at which the normal stop time management timer value changes from 1 to 0) In the setting area of the RAM 31c, “normally inactive” is set. In the general state update process in the case where the general map is not in operation, the process proceeds to the next S22 without doing anything.

  In S22, a drawing related lottery process is performed. In this general map-related lottery process, the open / close control of the general map variable game and the second special chart start opening 26d is not performed (the state of the normal map is not in operation), and the pending general map variable game is not held. When the number is 1 or more, it is decided whether to win or not to win the result of the variable figure game by random lottery based on the random number value stored in the random number value storage area. When the winning judgment is made and the winning is made, the winning flag provided in the RAM 31c is set to ON.

  If unsuccessful, turn off the winning flag. Regardless of the result of the hit determination, next, the value of the random number counter for generating the normal figure timer random value is acquired as the normal figure timer random number value, and a plurality of fluctuation times are obtained based on the acquired general figure timer random number value. One time is selected to display the variable map on the general map display device 22a, and this variable display time is stored as a normal map variable display time in a general map variable time storage area provided in the RAM 31c.

  In addition, the number of pending general figure variable games is stored in the usual figure pending number storage area provided in the RAM 31c. The value obtained by subtracting 1 is re-stored in the usual figure number-of-holds storage area. Also, the random number value used for the hit determination is deleted.

  Subsequently, the special figure state update process for each of the special figure 1 and the special figure 2 is performed. First, the special figure state update process (the special figure 2 state update process) for the special figure 2 is performed (S23). In the special figure 2 state update process, one of the following eight processes is performed in accordance with the state of the special figure 2. For example, in the special figure 2 state update process in the middle of the special figure 2 variable display (the value of the above-mentioned special figure 2 display symbol update timer is 1 or more), the 7-segment LED constituting the second special symbol display device 22c is turned on. Performs lighting / extinguishing drive control that repeatedly turns off. By performing this control, the second special symbol display device 22c performs the variation display of the special figure 2 (special figure 2 variable game).

  Further, the RAM 31c of the main control unit 30 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. 8A is on, the special figure probability fluctuation flag is off, and the common figure probability fluctuation flag is on. When the special figure B, 2R big hit flag is on, the special figure probability fluctuation flag is on, and the general figure probability fluctuation flag is also on, the special figure C, 2R big hit flag is on, the special figure probability fluctuation flag is off, When the probability fluctuation flag is on, the special figure D, 2R jackpot flag is on, the special figure probability fluctuation flag is on, and when the common figure probability fluctuation flag is on, the special figure E, 2R jackpot flag is on, special chart Probability flag is off, normal When the rate fluctuation flag is also off, the special figure F, when the first small hit flag is on, the special figure G, when the second small hit flag is on, the special figure H, and the first off flag are on. In such a case, the 7-segment LED constituting the second special symbol display device 22c is controlled to be turned on / off so that the special figure I and the second off-flag are turned on, respectively, so that the special figure I is in the respective mode. A setting indicating that the special figure 2 stop display is in progress is made in the setting area of the RAM 31c.

  By performing this control, the second special symbol display device 22c has a 15R special jackpot symbol (special symbol A), a 15R jackpot symbol (special symbol B), a sudden probability variation symbol (special symbol C), and a sudden time-short symbol symbol (special symbol). D), hidden probability variation (special E), suddenly normal (special F), first small hit (special G), second small hit (special H), first off symbol (special) Any one of the symbols I) and the first off-set symbol (special symbol J) is confirmed and displayed. 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 31c in order to maintain the display for a predetermined stop display period (for example, 500 msec). With this setting, the specially displayed special figure 2 is stopped and displayed for a predetermined period, and the result of the special figure 2 variable game is notified to the player.

  In addition, if the time reduction number stored in the time reduction number storage unit provided in the RAM 31c is 1 or more, 1 is subtracted from the time reduction number, and if the subtraction result becomes 1 to 0, the special figure probability is changing. If not (details will be described later), the time reduction flag is turned off. Further, the hourly flag is also turned off during the big hit game (in the special game state).

  In addition, in order to execute the general command rotation stop setting transmission process in the command setting transmission process (S27), 4H is additionally stored as transmission information (general information) in the transmission information storage area described above, and the pattern for stopping the variable display is displayed. Special figure 2 identification information indicating that it is special figure 2 is additionally stored in the RAM 31c 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 S23 at the timing when the predetermined stop display period ends (the special figure 2 stop time management timer value changes from 1 to 0), the RAM 31c Is set in the setting area of, and waiting for a predetermined winning effect period (for example, 3 seconds), that is, a period in which an image is displayed to notify the player that the big win by the decorative symbol display device 21 is started. For this purpose, 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 31c. Further, 5H is additionally stored as transmission information (command type) in the transmission information storage area described above in order to execute the general command winning effect setting transmission process in the command setting transmission process (S27).

  Further, in the special figure 2 state update process that starts at the timing when the predetermined winning effect period ends (the timing when the value of the special figure 2 standby time management timer changes from 1 to 0), a predetermined release period (for example, 29 seconds) Or until a winning of a predetermined number of game balls (for example, 10 balls) is detected at the variable start opening 26e.) A signal for holding the door member in an open state by a solenoid for opening and closing the door member of the variable start opening 26e. And information indicating the opening period is set in the storage area of the door opening time management timer provided in the RAM 31c. As described above, when the result of the special figure 2 variable game is a big hit, the gaming state shifts to a gaming state having a high advantage for the player in that the variable starting port 26e can be entered.

  Further, 7H is additionally stored as transmission information (command type) in the above-described transmission information storage area in order to execute the general command big prize opening setting transmission processing in the command setting transmission processing (SB33).

  Further, in the special figure 2 state update process S23 that starts at the timing when the predetermined opening period ends (the timing when the door opening time management timer value changes from 1 to 0), the predetermined closing period (for example, 1.5 seconds) ) A signal for holding the door member in a closed state is output to the solenoid for opening and closing the door member 1301 of the variable start port 26e, and information indicating the closing period is stored in the storage area of the door closing time management timer provided in the RAM 31c. Set. Further, 8H is additionally stored as transmission information (command type) in the above-described transmission information storage area in order to execute the general command big prize closing setting transmission process in the command setting transmission process (S27).

  In addition, the door member opening / closing control is repeated a predetermined number of times (15 rounds or 2 rounds in the present embodiment), and in the special figure 2 state update process S23 that starts at the end timing, a predetermined end effect period (for example, 3 seconds) ) That is, the effect standby in the storage area of the effect standby time management timer provided in the RAM 31c in order to set so as to wait for a period during which an image for informing the player that the big hit by the decorative symbol display device 21 is ended is displayed. Set information indicating the period.

  Also, if the ordinary probability change flag is set to ON, simultaneously with the end of the jackpot game, the time reduction number 100 is set in the time reduction number storage unit provided in the RAM 31c, and the time reduction flag provided in the RAM 31c. Turn on. If the usual time probability variation flag is set to OFF, the time reduction number is not set in the time reduction number storage unit, and the time reduction flag is not turned ON.

  The short time here means that the pachinko machine 1 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. That is, when the time reduction flag is set to ON, the gaming state shifts to a gaming state where the advantage for the player is high.

  If the short time flag is set to ON at this time, it is a normal high probability state. In the ordinary high probability state, compared to the ordinary low probability state, if the common figure variable game is hit, there is a high possibility that the variation time will be shortened. Also, the fluctuation time of the normal figure variable game is shorter in the normal figure high probability state than in the normal figure low probability state. Further, in the normal high-probability state, the opening time in one opening of the pair of blade members of the second special start port 26d tends to be longer than in the normal low-probability state. In addition, the pair of blade members are more likely to be opened in the normal high probability state than in the normal low probability state.

  In addition, as described above, the hourly flag is set to off during the big hit game (in the special game state). Therefore, the normal low probability state is maintained during the jackpot game. This is because, if the game is in a high probability state during a jackpot game, a large number of games are played in the second special figure start port 26d until a predetermined number of game balls enter the variable start port 26e during the jackpot game. There is a problem that a ball enters and the number of game balls that can be acquired during the jackpot increases, resulting in an increase in euphoria. This is to solve this problem.

  Further, 6H is additionally stored as transmission information (command type) in the transmission information storage area described above in order to execute the general command end effect setting transmission process in the command setting transmission process (S27).

  Further, in the special figure 2 state update process S23 that starts at the timing when the predetermined end production period ends (the timing when the production standby time management timer value changes from 1 to 0), the special region 2 is not set in the setting area of the RAM 31c. Set in operation. Further, if the result of the special figure 2 variable game is out of the way, the off flag is turned on as will be described later. When this miss flag is on, the special figure 2 state update process S23 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) is also obtained. In the setting area of the RAM 31c, the special figure 2 inactive state is set. In the special figure 2 state update process S23 when the special figure 2 is not in operation, nothing is done and the process proceeds to the next SB27.

  Then, the special figure state update process (special figure 1 state update process) about special figure 1 is performed (S24). 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 S23 and S24 is completed, a special figure related lottery process for each of special figure 1 and special figure 2 is performed. Also here, the special figure related lottery process (special figure 2 related lottery process) for special figure 2 is performed first (S25), and then the special figure related lottery process for special figure 1 (special figure 1 related lottery process). (S26). Also for these special drawing related lottery processes, the main control unit 30 performs the special figure 2 related lottery processing before the special figure 1 related lottery processing, so that the special figure 2 variable game start condition and the special figure 1 fluctuation Even if the game start conditions are satisfied at the same time, since the special figure 2 variable game is changing first, the special figure 1 variable game does not start changing.

  Further, the notification of the result of the special symbol variation game jackpot determination by the decorative symbol display device 21 is performed by the sub-control unit 40, and the lottery result of the lottery based on the winning at the second special diagram starting port 26d is notified, This is prioritized over the notification of the lottery result of the lottery based on the winning at the first special figure starting port 26c.

  In S27, command setting transmission processing is performed, and various commands are transmitted to the sub-control unit 40. The output schedule information transmitted to the sub-control unit 40 is composed of 16 bits in this embodiment, bit 15 is strobe information (indicating that data is set when ON), bits 11 to 14 Is a command type (in this embodiment, command types such as basic command, symbol variation start command, symbol variation stop command, winning effect start command, end effect start command, jackpot round number designation command, power recovery command, RAM clear command, etc. Bits 0 to 10 are configured with command data (predetermined information corresponding to the command type).

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

  When the command type indicates a basic command, device information in the command data, presence / absence of winning at the first special figure starting port 26c, presence / absence of winning at the second special figure starting port 26d, winning of the variable starting port 26e Includes presence or absence.

  In the general command rotation start setting transmission process, the value of the 15R jackpot flag or 2R jackpot flag, the value of the special figure probability variation flag, the special figure 1 related lottery process, and the special figure 2 are stored in the RAM 31c as the command data. Information indicating the timer number selected in the lottery process, the number of the first special figure variable game or the second special figure variable game held, etc. is set.

  In the general command rotation stop setting transmission process described above, information indicating the value of the 15R jackpot flag, the value of the 2R jackpot flag, the value of the special figure probability variation flag, etc. stored in the RAM 31c is set in the command data.

  In the general command winning effect setting transmission process, the command data is stored in the RAM 31c, the decorative symbol display device 21, the various lamps 44b, the effect control information output to the speaker during the winning effect period, and the value of the special figure probability variation flag. The information indicating the number of the first special figure variable game or the second special figure variable game that is on hold is set.

  In the general command big prize opening setting transmission process, the number of big hits stored in the RAM 31c, the value of the special figure probability variation flag, the pending first special figure variable game or the second special figure variable game is stored in the command data. Set information such as number.

  In the general command big prize opening closing setting transmission processing, the number of big hits stored in the RAM 31c, the value of the special figure probability variation flag, the pending first special figure variation game or the second special figure variation game are stored in the command data. Set information such as number. In S27, a general command special figure hold increasing process 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 31c, notice information (preliminary notice information, false) Set either advance notice information or no advance notice information).

  In the sub-control unit 40, it is possible to determine the effect control according to the change of the game control in the main control unit 30 according to the command type included in the received output schedule information, and the command data included in the output schedule information Based on this information, the contents of the effect control can be determined.

  In S28, an external output signal setting process is performed. In this external output signal setting process, the game information stored in the RAM 31c is output to the information input circuit 34a separate from the pachinko machine 1 via the information output circuit 34.

  In S29, a device monitoring process is performed. In this device monitoring process, when the signal states of the various sensors stored in the signal state storage area in S13 are read and an error is detected, device information indicating the presence / absence of an error is included in the transmission information to be transmitted to the sub-control unit 40. Set. Further, various solenoids are driven to control the opening / closing of the second special symbol start port 26d and the variable start port 26e, or the normal symbol display device 22a, the first special symbol display device 22b, the second special symbol display device 22c, Display data to be output to the various status display sections 35b and the like is set in the output port of the I / O 31d. Further, the output schedule information set in the payout request number transmission process (S20) is output to the sub-control unit 40 via the output port (I / O 31d).

  In S30, it is monitored whether or not the low voltage signal is on. If the low voltage signal is on (when power supply shutoff is detected), the process proceeds to S31. If the low voltage signal is off (power supply shutoff is not detected), the process proceeds to S32.

  In S31, a timer interrupt end process is performed. In this timer interrupt termination process, the value of each register temporarily saved in S11 is set in each original register, interrupt permission is set, etc., and then the main control unit main process shown in FIG. Return.

  On the other hand, in S32, a specific variable or stack pointer for returning to the power-off state at the time of power recovery is saved in a predetermined area of the RAM 31c as return data, and power-off processing such as initialization of the input / output port is performed. Then, the process returns to the main control unit main process shown in FIG.

<Processing of Sub Control Unit 40>
The process of the sub control unit 40 will be described with reference to FIG. FIG. 4A is a flowchart of main processing executed by the CPU 41a of the sub-control unit 40. FIG. 4B is a flowchart of command reception interrupt processing of the sub control unit 40. FIG. 5C is a flowchart of the timer interrupt process of the sub control unit 40.

  First, in S41 of FIG. 11A, various initial settings are performed. When the power is turned on, an initialization process is first executed in S41. In this initialization process, initialization of input / output ports, initialization of a storage area in the RAM, and the like are performed. In S42, it is determined whether or not the timer variable is 10 or more, and this process is repeated until the timer variable becomes 10. When the timer variable becomes 10 or more, the process proceeds to S43. In S43, 0 is assigned to the timer variable.

  In S44, command processing is performed. The CPU 41a of the sub control unit 40 determines whether a command is received from the main control unit 30 or not. In S45, an effect control process is performed. For example, when there is a new command in S44, the effect data corresponding to this command is read from the ROM 41b, and the effect data is updated when the effect data needs to be updated.

  In S46, when pressing of the chance button 10a is detected, processing for changing the effect data updated in S45 to effect data corresponding to the pressing of the chance button 10a is performed. In S47, when there is a command to the sound source IC 43a in the effect data read in S45, this command is output to the sound source IC 43a.

  In S48, when there is a command to the various lamps 44b in the effect data read in S45, this command is output to the drive circuit 43b. In S49, when there is a command to the effect movable body 24 in the effect data read in S45, this command is output to the drive circuit 43d. In S50, when there is a control command to be transmitted to the display control unit 50 in the effect data read out in S45, the control command is set to be output, and the process returns to S42.

  Next, the command reception interrupt process of the sub-control unit 40 will be described with reference to FIG. This command reception interrupt process is a process executed when the sub control unit 40 detects a strobe signal output from the main control unit 30. In S51 of the command reception interrupt process, the command output from the main control unit 30 is stored in the command storage area provided in the RAM 41c as an unprocessed command.

  Next, timer interrupt processing executed by the CPU 41a of the sub control unit 40 will be described with reference to FIG. The sub-control unit 40 includes a hardware timer that generates a timer interrupt at a predetermined cycle (in this embodiment, once every 2 ms). The timer interrupt process is triggered by the timer interrupt at a predetermined cycle. Run with. In S52, 1 is added to the value of the timer variable storage area of the RAM 41c described in S42 in the sub-control unit main process shown in FIG. 11A, and the result is stored in the original timer variable storage area. Therefore, in S42, the value of the timer variable is determined to be 10 or more every 20 ms (2 ms × 10). In S53, transmission of the control command to the display control unit 50 set in S50, update processing of the random number for production, and the like are performed.

<Pattern arrangement>
A symbol arrangement applied to each of the reels 110 to 112 will be described with reference to FIG. This figure is a diagram in which the arrangement of symbols applied to each reel (left reel 110, middle reel 111, right reel 112) is developed in a plane.

  In each reel 110 to 112, a plurality of types (eight types in this embodiment) of symbols shown on the right side of the figure are arranged in a predetermined number of frames (21 frames of numbers 0 to 20 in this embodiment). Also, numbers 0 to 20 shown at the left end of the figure are numbers indicating the arrangement positions of symbols on the reels 110 to 112. For example, in the present embodiment, the “replay” symbol for the number 1 frame on the left reel 110, the “bell” symbol for the number 0 frame on the middle reel 111, and the “bell” symbol for the number 2 frame on the right reel 112. "Watermelon" design is arranged respectively.

<Type of winning prize>
Next, the types of winning combinations of the slot machine 100 will be described with reference to FIG. This figure shows the types of winning combinations (including actuating combinations), symbol combinations corresponding to each winning combination, and the operation or payout of each winning combination.

  Among the winning combinations in this embodiment, the big bonuses (BB1, BB2) and the regular bonus (RB) are used as a combination for shifting to the bonus game, and the replay (replay) is a replay without newly inserting a medal. Each winning combination is sometimes distinguished from a winning combination and sometimes called an “acting combination”. However, in the “winning combination” in this embodiment, a big bonus, a regular bonus, and a replay that are operating combinations are included. included. In addition, “winning” in the present embodiment includes a case where a symbol combination of an actuator not accompanied by a medal payout (without medal payout) is displayed on an active line, for example, a big bonus, regular Includes bonuses and replay wins.

  The winning combination of the slot machine 100 includes a big bonus (BB1, BB2), a regular bonus (RB), a small combination (cherry, watermelon, bell), and replay (replay). Needless to say, the type of winning combination is not limited to this and can be arbitrarily adopted.

  “Big Bonus (BB1, BB2)” (hereinafter sometimes simply referred to as “BB”) is a special combination (operating combination) in which a big bonus game (BB game), which is a special game, is started by winning a prize. . Corresponding symbol combinations are “white 7-white 7-white 7” for BB1, and “blue 7-blue 7-blue 7” for BB2. Further, flag carryover is performed for BB1 and BB2. That is, when BB1 and BB2 are won internally, a flag indicating this is set (stored in a predetermined area of the RAM 308 of the main control unit 300), but even if BB1 and BB2 are not won in the game, a prize is won. Until then, the flag indicating the internal winning is maintained, and even after the next game, BB1 and BB2 are being internally selected, and the symbol combination corresponding to BB1 “white 7-white 7-white 7”, the symbol corresponding to BB2 The combination “blue 7-blue 7-blue 7” is in a state of winning a prize.

  The “regular bonus (RB)” is a special combination (operating combination) in which a regular bonus game (RB game) is started by winning. The corresponding symbol combination is “bonus-bonus-bonus”. Note that the RB carries over the flag as well as the above-mentioned BB. However, in the big bonus game (BB game) (details will be described later), the regular bonus game (RB game) is won internally and the combination of symbols is displayed on the winning line. In addition, the regular bonus game is started after the start of the big bonus game, and when the regular bonus game is finished once, the regular bonus game is automatically started so that the next regular bonus game is immediately started. It is good. “Short (cherry, watermelon, bell)” (hereinafter, simply referred to as “cherry”, “watermelon”, “bell”) is a winning combination in which a predetermined number of medals are paid out by winning. The symbol combinations are “cherry-ANY-ANY” for cherry, “watermelon-watermelon-watermelon” for watermelon, and “bell-bell-bell” for bell. The corresponding payout number is as shown in FIG. In the case of “cherry-ANY-ANY”, the symbol of the left reel 110 may be “cherry”, and the symbol of the middle reel 111 and the right reel 112 may be any symbol.

  “Replay” is a winning combination (operating combination) in which a game can be performed without inserting a medal (game medium) in the next game by winning, and no medal is paid out. The corresponding symbol combination is “replay-replay-replay” for replay.

<Type of gaming state>
Next, the types of gaming state of the slot machine 100 will be described. In the present embodiment, the gaming state of the slot machine 100 is roughly classified into a normal game, a BB game, an RB game, and an internal winning game of a big bonus (BB) and a regular bonus (RB). However, it may be divided into a general game, a BB game, and an RB game.

<Normal game>
The winning combinations that are internally won for normal games include a big bonus (BB), regular bonus (RB), replay (replay), and small roles (cherry, watermelon, bell). “Big Bonus (BB)” is a special combination (operating combination) in which a big bonus game (BB game), which is a special game, is started by winning. “Regular Bonus (RB)” is a special combination (operating combination) that starts a regular bonus game (RB game) upon winning. The “replay” (replay) is a winning combination (operating combination) in which a game can be performed without a medal being inserted in the next game by winning, and no medal is paid out. The “small role” is a winning combination in which a predetermined number of medals are paid out by winning.

  In addition, the internal winning probability of each combination is a range of random values obtained at the time of internal lottery from numerical data corresponding to the range of lottery data associated with each combination from lottery data prepared for normal games. It is calculated by the value divided by the numerical data (for example, 65535). The lottery data prepared for the normal game is divided into several numerical ranges in advance, and each combination and lose is associated with each numerical range. It is determined whether the random number value obtained as a result of executing the internal lottery is a value corresponding to the lottery data corresponding to which combination, and the internal lottery combination is determined. This lottery data is provided with settings 1 to 6 in which the winning probabilities of at least one combination are different, and a game shop clerk can arbitrarily select and set any set value.

  In the normal game, the result of the internal lottery is set to be roughly lost (big bonus (BB), regular bonus (RB), replay (replay) and small role won), and the medal to win The total number is less than the total number of medals inserted. Therefore, it is a gaming state that is disadvantageous for the player. However, when a predetermined condition is satisfied (for example, when a specific symbol combination is displayed), it is a gaming state that may be changed to increase the probability of internal winning of replaying. In this case, When a predetermined number of medals are paid out by winning a small role, there are cases where the total number of medals to be acquired exceeds the total number of medals inserted, resulting in a gaming state that is beneficial to the player.

<BB game>
The BB game is set so that the player has a higher gaming advantage than the normal game. That is, the BB game is in a gaming state in which the total number of medals to be acquired exceeds the total number of medals inserted. In this embodiment, the BB game is started by winning a big bonus (BB), and an RB game (described later) can be continuously executed repeatedly, and a predetermined number (for example, during the game) The process ends when more than 465 medals are obtained. However, the BB game does not allow the RB game to be executed continuously and repeatedly, and sets the role to start the RB game (the symbol combination is, for example, replay-replay-replay), and if this role is won internally, or The RB game may be set to start when winning. Furthermore, in the BB game, when the BB general game excluding the RB game during the BB game is executed a predetermined number of times (for example, 30 times), or the number of the RB games executed during the BB game is a predetermined number of times. It may be made to end when it reaches (for example, three times).

<RB game>
The RB game is set so that the player has a higher gaming advantage than the normal game. That is, the RB game is in a gaming state in which the total number of medals to be acquired exceeds the total number of medals inserted. In this embodiment, the RB game is started by winning a regular bonus (RB), and a predetermined role is set to a variation that increases the probability of internal winning (for example, “setting 1” or “normal game”). Increase the internal winning probability 1/15 of “small role 1” to an internal winning probability 1 / 1.2 which is a predetermined value) and win a predetermined number (for example, 8 times) It ends when there is. A BB game ends when a predetermined number of wins are made (for example, 8 times) or when the number of RB games executed during the RB game reaches a predetermined number of times (for example, 8 times). You may make it do.

<Big winning (BB) and regular bonus (RB) internal winning games>
The winning combination that is internally won for the internal winning game of the big bonus (BB) and the regular bonus (RB) includes a replay and a small role. The big bonus (BB) and the regular bonus (RB) are not won internally, and are game states in which a symbol combination corresponding to the big bonus (BB) or the regular bonus (RB) can be won.

  However, the probability of the internal winning of the replay may be changed from the next game that has been internally won for the big bonus (BB) and the regular bonus (RB). Until the symbol combination corresponding to the big bonus (BB) and the regular bonus (RB) wins, the total number of medals to be acquired is almost the same as the total number of inserted medals, and it is advantageous for the player. It is good also as a gaming state whose degree is higher than a normal game.

<Main control unit main processing>
The main control unit main 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 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) 338 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 resets by a reset interrupt and executes the main process of the main control unit shown in FIG. 16 in accordance with a control program stored in advance in the ROM 306.

  When the power is turned on, first, various initial settings are performed in S101. In this initial setting, setting of the stack initial value to the stack pointer (SP) of the CPU 304, setting of interrupt inhibition, initial setting of the I / O 310, initial setting of various variables stored in the RAM 308, operation permission to the WDT 313, and initial setting Set the value.

  In S102, medal insertion / start operation acceptance processing is executed. Here, it is checked whether or not a medal has been inserted, and the winning line display lamp 120 is turned on in response to the insertion of the medal. Note that when a re-win is won in the previous game, a process of inserting the same number of medals as the number of medals inserted in the previous game is performed, so that it is not necessary for the player to insert medals. Further, it is checked whether or not the start lever 135 has been operated. If there is an operation of the start lever 135, the process proceeds to S103.

  In S103, the number of inserted medals is determined, and an effective winning line is determined. In S104, the random number generated by the random number generation circuit 316 is acquired. In S105, the winning combination lottery table stored in the ROM 306 is read according to the current gaming state, and an internal lottery is performed using this and the random value acquired in S104. As a result of the internal lottery, when any winning combination is won internally, the internal winning flag of the winning combination is turned ON. In S106, reel stop data is selected based on the internal lottery result.

  In S107, rotation of all reels 110 to 112 is started. In S108, the stop buttons 137 to 139 can be received. When any one of the stop buttons is pressed, one of the reels 110 to 112 corresponding to the pressed stop button is selected as the reel stop control data selected in S106. Stop based on. The reel stop control basically allows the combination of symbols corresponding to the winning combination to be displayed when there is an internal winning winning combination, and the symbol corresponding to any combination in the case of a loss, etc. Reel stop control such as so-called pull-in and kick-out is performed so that combinations are not displayed.

  When all the reels 110 to 112 are stopped, the process proceeds to S109. In S109, a winning determination is performed. Here, when a picture combination corresponding to some winning combination is displayed on the activated winning line 114, it is determined that the winning combination is won. For example, if “bell-bell-bell” is aligned on the activated winning line, it is determined that the player has won the bell. Also, the internal winning flag is reset unless the flag is carried over.

  In S110, if any winning combination with payout is won, the number of medals corresponding to the winning combination is paid out according to the number of winning lines. In S111, game state control processing is performed. In the game state control process, a process related to transition of each game state of normal game, BB game, RB game, and internal winning game is performed, and the game state is shifted when those start conditions and end conditions are satisfied. Thus, in this embodiment, a privilege is given to the player based on the combination of symbols that are stopped and displayed. Thus, one game is completed. Thereafter, returning to S102 and repeating the above-described processing, the game proceeds.

<Removal structure of start lever unit 135>
Since the start lever unit 135 is operated frequently by the player, maintenance is required by use. For this reason, in this embodiment, the start lever unit 135 is detachable from the front door 102. The structure will be described below with reference to FIGS. FIG. 17 is a perspective view of the slot machine 100 with the front door 102 in an open state, FIG. 18A is an explanatory view of the regulating member 200, and FIGS. 18B to 18D are explanatory views of the attachment / detachment structure of the start lever unit 135. is there.

  As shown in FIGS. 18B to 18D, in the case of the present embodiment, the start lever unit 135 has a front portion 135c inserted into an opening portion (mounting hole) 102 ′ provided in the front door 102, whereby the front portion 135c is inserted into the front portion. The structure is attached to the door 102. In the mounted state, the opening 102 ′ is blocked by the start lever unit 135.

  The start lever unit 135 has a shaft portion 135a having a smaller diameter than the body portion 135c and a flange portion 135b having a diameter larger than the shaft portion 135a and the same diameter (or slightly smaller diameter) as the body portion 135c at the rear end portion thereof. In the mounted state, these are located on the back side of the front door 102 as shown in FIGS. 17 and 18B to 18D. Accordingly, by attaching the regulating member 200 to the shaft portion 135a, the start lever unit 135 is restricted from being pulled out from the opening 102 'to the front side of the slot machine 100 and removed.

  As shown in FIG. 18A, the regulating member 200 has a U-shape, and is mounted on the start lever unit 135 by sandwiching the shaft portion 135a between the U-shaped branch portions. The regulating member 200 is slidably supported on the back surface of the front door 102. As shown in FIG. 18B, in a state where the regulating member 200 is removed from the shaft portion 135a (release position), the start lever unit 135 is removed from the opening 102 ′ to the front side of the slot machine 100 and removed. Can do. Thereby, the operator can perform maintenance of the start lever unit 135.

  On the other hand, as shown in FIG. 18C and FIG. 17, in a state where the regulating member 200 is mounted on the shaft portion 135a (regulated position), the start lever unit 135 is moved from the opening 102 ′ to the front side of the slot machine 100. When trying to pull out, the flange 135b catches on the restricting member 200, and the restricting member 200 catches on the back surface of the front door 102, so that removal is restricted. Since the start lever unit 135 can be attached and detached by the sliding operation of the regulating member 200, the operation can be facilitated.

  As shown in FIG. 17, the main body unit 101 is provided with a block-like release operation blocking unit 201. When the restricting member 200 is positioned at the restricting position and the front door 102 is closed, the release operation blocking portion 201 is located on the side of the restricting member 200 as shown by a broken line in FIG. 17 and as shown in FIG. As a result, the restriction member 200 cannot be moved to the release position, and the restriction release operation of the restriction member 200 is prevented. Therefore, when the front door 102 is in the closed state, an unauthorized person cannot try to release the restriction by the restriction member 200, and the start lever unit 135 can be prevented from being removed illegally.

  Thus, in the present embodiment, unauthorized removal can be prevented while maintaining the ease of attaching and detaching the start lever unit 135. Further, when the front door 102 is closed from the open state, if the restriction member 200 is in the release position, the restriction member 200 and the release operation blocking unit 201 interfere with each other, so that the front door 102 is difficult to close. Therefore, it is possible to make the operator aware that the restriction member 200 is not located at the restriction position.

<Examples of other attachment / detachment structures>
The attachment / detachment structure based on the same idea as the attachment / detachment structure of the start lever unit 135 can be applied to other components of the slot machine 100. FIGS. 19A and 19B are explanatory views of the attachment / detachment structure of the substrate case 210. FIG. The substrate case 210 accommodates, for example, a control substrate for the liquid crystal display device 157.

  The substrate case 210 is attached to a slot-like opening 102a provided on the back surface of the front door 102, and closes the opening 102a. A pair of restricting members 220 slidable to the left and right are provided on the upper edge of the opening 102. A pair of spaced apart left and right protruding portions 211 projecting upward is formed at the front end of the substrate case 210 in the mounting direction, and the spacing is slightly wider than the total width of the pair of regulating members 220.

  Thus, as shown in FIG. 19B, when the pair of restricting members 220 are moved to the center (release position), the protrusion 211 and the restricting member 220 do not interfere with each other. it can. When the pair of restricting members 220 are separated from each other in a state where the substrate case 210 is attached to the opening 102a, the protrusion 211 and the restricting member 220 interfere with each other, so that the removal of the substrate case 210 from the opening 102a is restricted. Is done. Since the substrate case 210 can be attached and detached by the sliding operation of the regulating member 220, the operation can be facilitated.

  As shown in FIG. 19A, the main body 101 is provided with a block-like release operation blocking portion 221. When the restricting member 220 is positioned at the restricting position and the front door 102 is closed, the release operation blocking portion 221 is located at a position sandwiched between the pair of restricting members 220. As a result, the restriction member 220 cannot be moved to the release position, and the restriction release operation of the restriction member 220 is prevented. Therefore, when the front door 102 is in a closed state, an unauthorized person cannot try to release the restriction by the restriction member 220, and the board case 210 can be prevented from being removed illegally.

  As described above, in the present embodiment, unauthorized removal can be prevented while maintaining the ease of attaching and detaching the substrate case 210. Further, when the front door 102 is closed from the open state, if the restriction member 220 is in the release position, the restriction member 220 and the release operation blocking portion 221 interfere with each other, which makes it difficult to close the front door 102. Therefore, it is possible to make the operator aware that the restriction member 220 is not located at the restriction position.

<Reference example>
In the above-described embodiment, the restriction release operation is prevented by using the rotation of the door body. However, the removal of the component itself can also be controlled by using the rotation of the door body. FIGS. 20A and 20B are explanatory views showing a removal restricting structure as a reference example. The button unit 230 shown in the figure is a button instead of the MAX bet button 132, for example, and is screwed to the front door 102 (not shown in FIG. 20) with a screw portion 231a. The button unit 230 is engaged with the lower portion of the operation unit 231 with the operation unit 231, the LED substrate 232 for causing the operation unit 231 to emit light from the inside, and the operation unit 231 housing the LED substrate 232. And a cap portion 233 for preventing the 232 from falling off.

  The restricting member 240 is a member that is attached to the button unit 230 so that the tip portion of the restricting member 240 has a U-shape and sandwiches an intermediate portion of the button unit 230. . When the front door 102 is opened, the regulating member 240 is detached from the button unit 230 as shown in FIG. 20B, and when the front door 102 is closed, the regulating member 240 is moved as shown in FIG. The button unit 230 is attached.

  In order to remove the button unit 230, the button unit 230 must be rotated to unscrew the screw portion 231a. As shown in FIG. 20A, the regulating member 240 is attached to the button unit 230. In such a situation, the button unit 230 cannot be rotated by being restricted by the restriction member 240. Therefore, removal of the button unit 230 is regulated.
