As a result, the input flow path 21a and the discharge side flow path 21c are in communication with each other, so that the medals flowing down the input flow path 21a fall into the discharge side flow path 21c and are discharged from the medal discharge port 20.
Further, in the flow path switching plate 21d, when the blocker solenoid 69 is excited, as shown in FIGS. 8A and 8B, the upper portion of the flow path switching plate 21d is in the left direction (arrow direction) in the figure with the shaft 21da as a fulcrum. The upper end 21db of the flow path switching plate 21d is projected from the recess 21e by swinging the flow path 21d. Therefore, the medals flowing down the insertion flow path 21a are taken in along the upper end 21db of the flow path switching plate 21d. It flows down into the side flow passage 21b and is guided to the medal tank 5a.

Further, as shown in FIG. 8A, the intake side flow passage 21b is provided with a first insertion medal sensor 68a and a second insertion medal sensor 68b for detecting passage of medals flowing down the intake side passage 21b. Has been. The first inserted medal sensor 68a and the second inserted medal sensor 68b are provided as the inserted medal-related sensor 68 (see FIG. 5) described above.
As shown in the figure, the first inserted medal sensor 68a is provided on the upstream side of the second inserted medal sensor 68b in the intake side flow passage 21b to prevent passage of a disc-shaped medal flowing down the intake side flow passage 21b. It is possible to detect the first-insertion medal sensor 68a and the second-insertion medal sensor 68b in this order.
In the first inserted medal sensor 68a and the second inserted medal sensor 68b, when one medal passes, only the first inserted medal sensor 68a is ON, and both the first inserted medal sensor 68a and the second inserted medal sensor 68b. Is ON, and only the second inserted medal sensor 68b is arranged in proximity so that the state transitions in the order of ON.
Further, since the first inserted medal sensor 68a and the second inserted medal sensor 68b are arranged so as to detect the end portion of the medal (in this example, the upper end portion of the medal), if one medal is continuously inserted, one After the second medal sensor 68b is turned off by passing the second medal sensor 68b, the succeeding medal passes the first inserted medal sensor 68a and the first inserted medal sensor 68a is turned on. It is set to be ON so that it is possible to reliably detect individual medals that have been continuously inserted.

FIG. 9 schematically shows various sensors related to medal detection, which are provided in the flow-down path from the medal insertion slot 12 to the medal tank 5a, including the first insertion medal sensor 68a and the second insertion medal sensor 68b. There is.
Although not shown in FIGS. 7 and 8, a selector sensor 67 is provided in the insertion passage 21 a of the medal selector 21. A post passage sensor 68c is provided as one of the above-mentioned inserted medal-related sensors 68 in the medal flow path that connects the take-in side flow path 21d and the medal tank 5a in the medal selector 21.

The selector sensor 67, the post-passage sensor 68c, the first throw-in medal sensor 68a, and the second throw-in medal sensor 68b are, for example, photo sensors and each include a light projecting unit and a light receiving unit. The passage of the medal is detected by the light receiving unit detecting the interruption of the light from the light projecting unit when the medal passes between and.
In the following description, the first inserted medal sensor 68a and the second inserted medal sensor 68b may be referred to as "sensor 1" and "sensor 2", respectively.

<4. Configuration and rotating reel related to spinning cylinder rotation>

The structure for rotating the rotating reel 4 and the relationship between the symbol formed on the rotating reel 4 and the step position will be described with reference to FIGS. 10 to 12.
FIG. 10 is an explanatory diagram of a configuration related to origin detection for the rotating reels 4a, 4b, and 4c. The origin detection is detection of a specific position defined on each rotating reel 4a, 4b, 4c, that is, the origin position 101.
Since the configuration related to the origin detection is the same for each of the rotating reels 4a to 4c, only one rotating reel (denoted as the rotating reel 4) is shown here as a representative. FIG. 10A is a perspective view showing the configuration related to the origin detection, and FIG. 10B is a schematic sectional view showing the relationship between the detection target portion 410d formed on the rotating reel 4 and the origin position 101.

  In FIG. 10A, the center axis (denoted as “rotation axis Ra”) of the rotor 54r included in the stepping motor 54 that rotationally drives the rotation reel 4 is shown by a dashed line. The rotating reel 4 includes a reel drum 401 that is rotationally driven around the rotation axis Ra, a backlight unit 402 that is arranged inside the reel drum 401, and a base that directly or indirectly supports the reel drum 401. And a body 403.

The base body 403 is made of, for example, a synthetic resin, and has a base plate 403b formed in a substantially plate shape, and a protrusion 403t protruding from the base plate 403b in the direction along the rotation axis Ra. The base plate 403b is arranged along one side of the reel drum 401 in the left-right direction (here, the right side). The stepping motor 54 is fixed to one surface side (here, left surface side) of the base body 403 with the rotor 54r (rotating shaft Ra) directed to one side (left side here) in the left-right direction.
In this case, the projecting portion 403t projects leftward from the base plate 403b.

The reel drum 401 is configured to include two reel frames 410 and 411, and a belt-shaped reel seat 420 that is mounted in a cylindrical shape on the outer circumference of the reel frames 410 and 411. The reel frames 410 and 411 are made of, for example, black synthetic resin having no light transmittance or extremely low light transmittance, and outer peripheral portions thereof are formed as rim portions 410r and 411r, respectively. The rim portion 410r of the reel frame 410 and the rim portion 411r of the reel frame 411 are each formed in an annular shape along the left and right edges of the reel seat 420.
The reel frame 410 has a hub portion 410h that is detachably fixed to the rotor 54r of the stepping motor 54, and a plurality of spoke portions 410s that connect the rim portion 410r and the hub portion 410h in the radial direction. .

  Here, in the case of this example, the reel frame 411 is not directly connected to the reel frame 410, and the rim portion 411r of the reel frame 411 is connected to the rim portion 410r of the reel frame 410 via the reel seat 420. (Of course, the rim portion 411r and the rim portion 410r may be integrally connected at one or a plurality of positions in the circumferential direction).

The reel sheet 420 is formed of, for example, a colorless and transparent synthetic resin sheet in a band shape having a constant width, is wound around the rim portions 410r and 411r of the reel frames 410 and 411, and is attached by, for example, an adhesive. Although not shown in the drawing, a plurality of symbols are formed on the reel sheet 420 by printing.
The pattern forming area of the reel sheet 420 has a relatively high light transmittance, and when the LED of the backlight section 402 is turned on, the light emitting area thereof emits bright light.

  The index sensor 55 is composed of, for example, a transmissive photo sensor, and is attached to the tip portion of a projecting portion 403t projecting from the base plate 403b to the reel drum 401 in this example as shown in the figure. The index sensor 55 has a light emitting portion 551 and a light receiving portion 552 which are arranged such that the light emitting surface and the light receiving surface face each other in the radial direction of the reel frame 410.

  In the case of the present example, a predetermined spoke portion 410s of the reel drum 410 is provided with a detected portion 410d that protrudes in a direction facing the index sensor 55. The detected portion 410d is formed at a position that passes through the space between the light emitting portion 551 and the light receiving portion 552 of the index sensor 55 as the reel drum 401 rotates.

  With such a configuration, depending on the index sensor 55 as the transmissive photo sensor, the detected portion 410d may be provided between the light emitting unit 551 and the light receiving unit 552 once for each revolution of the reel drum 401 (rotating reel 4). It is possible to obtain a detection signal in which the ON pulse appears as the pulse passes.

  Here, as shown in FIG. 10B, in the detected portion 410d, one of both edges (ends) in a direction parallel to the rotation direction R (forward rotation direction) is positioned at the same rotation angle as the origin position 101. It is positioned so that Specifically, the detected portion 410d of the present example is positioned such that the edge on the rotation advancing direction side in the forward rotation direction (R) is located at the same rotation angle as the origin position 101.

The configuration for detecting the origin should not be limited to that described above. For example, instead of the protrusion-shaped detection target portion 410d, a detection target portion formed by a notch may be provided. In this case, the light emitting section 551 and the light receiving section 552 of the index sensor 55 may be arranged so that the light emitting section 551 receives the light emitted by the light emitting section 551 when the cutout portion comes along with the rotation of the rotating reel 4. Good.
The index sensor 55 is not limited to a transmissive photo sensor, but a reflective photo sensor may be used.

Next, stepping motors 54a, 54b, 54c for rotationally driving the rotary reels 4a, 4b, 4c will be described.
In the present embodiment, the stepping motors 54a, 54b, 54c are unipolar drive stepping motors, and each has two center-tapped drive windings. In the case of the present embodiment, the stepping motors 54a, 54b, 54c are driven by 1-2 phase excitation in which 1-phase excitation and 2-phase excitation are alternately repeated.

  FIG. 11A is a diagram showing the relationship between the two stators of the stepping motors 54a, 54b, 54c, the drive windings wound around each stator, and the rotational position (arrow) of the rotor. .. As shown in the figure, in the stepping motor of unipolar drive, the drive winding is center tapped, and one of the drive windings is divided into the winding portion A and the winding portion A bar. It is written as. In addition, the respective winding portions formed separately on the other side of the center tap in the other drive winding are referred to as a winding portion B and a winding portion B bar.

FIG. 11B shows the drive signal φ (drive current) given to the winding portions A, A bar, B, and B bar in the 1-2 phase excitation. As shown in the figure, the drive signal of the winding portion B bar is represented by φ1, the drive signal of the winding portion A bar is represented by φ2, the drive signal of the winding portion B is represented by φ3, and the drive signal of the winding portion A is represented by φ4.
As shown in FIG. 11B, in 1-2 phase excitation, eight steps 0 to 7 in the figure are repeated for the driving mode by the driving signals φ1 to φ4. In particular,

・ Step 0: φ1 = on, φ2 = off, φ3 = off, φ4 = off
First step: φ1 = on, φ2 = off, φ3 = off, φ4 = on
・ Second step: φ1 = off, φ2 = off, φ3 = off, φ4 = on
・ Third step: φ1 = off, φ2 = off, φ3 = on, φ4 = on
・ 4th step: φ1 = off, φ2 = off, φ3 = on, φ4 = off
・ Fifth step: φ1 = off, φ2 = on, φ3 = on, φ4 = off
・ 6th step: φ1 = off, φ2 = on, φ3 = off, φ4 = off
・ Seventh step: φ1 = on, φ2 = on, φ3 = off, φ4 = off

Is repeated. Thus, in the 1-2 phase excitation, two drive windings are simultaneously driven (that is, two stators are simultaneously excited) and one drive winding is driven. Steps (1, 3, 5, 7) in which only one is driven (only one of the stators is excited) are repeated alternately.

  The 1-2 phase excitation as described above causes the rotor to intermittently move to the positions of 0 → 1 → 2 → 3 → 4 → 5 → 6 → 7 → 0 as shown in FIG. 11A. The step angle can be halved as compared with the case of two-phase excitation, that is, intermittent movement to the position of 0 → 2 → 4 → 6 → 0. Specifically, the step angle of the stepping motors 54a, 54b, 54c is 360 ° / 8 = 45 °.

  As will be understood from the above description, the “step” mentioned here can be rephrased as the minimum rotational drive amount of the stepping motors 54a, 54b, 54c.

FIG. 11C is an explanatory diagram of an excitation data table referred to for realizing the 1-2 phase excitation as described above.
In the excitation data table, 0 to 7 of the excitation pointer (excitation phase pointer) PT correspond to the above steps 0 to 7, respectively, and drive signals φ1 to 1 for the excitation pointers PT 0 to 7, respectively. 4-bit excitation data representing on / off of φ4 is associated. In FIG. 11C, the hexadecimal notation of each excitation data and the two-phase excitation / one-phase excitation corresponding to each of the excitation pointers PT 0 to 7 are also shown. In this example, the excitation pointer PT is 4-bit information.
Here, for each of the drive signals φ1 to φ4, each 1-bit data representing on / off of each drive signal φ is referred to as “excitation data”. Further, the excitation data for the drive signal φ1 is referred to as “excitation data φ1”, and the excitation data for the drive signal φ2 is referred to as “excitation data φ2”. Similarly, the excitation data for the drive signal φ3 is referred to as “excitation data φ3”, and the excitation data for the drive signal φ4 is referred to as “excitation data φ4”.

As will be described later, the CPU 80a of the main control board 40 controls the driving of the stepping motors 54a, 54b, 54c based on the result of referencing the excitation data table. Specifically, the excitation pointer PT is cycled in the order of 0 → 1 → 2 → ... → 7 → 0 → ..., and stepping is performed based on the excitation data φ1 to φ4 corresponding to the current value of the excitation pointer PT. The control is performed so that the motors 54a, 54b, 54c are driven.
The shortest update cycle of the excitation pointer PT is a cycle for each timer interrupt process (FIG. 26) activated every 1.49 ms.
The excitation data table is stored in a storage unit such as the ROM 80b that can be read by the CPU 80a.

FIG. 12 is an explanatory diagram of symbols formed on the rotary reels 4a, 4b, 4c.
In this example, symbols for 21 frames are arranged along the rotation direction on the surfaces of the rotating reels 4a, 4b, 4c. In each of the rotating reels 4a, 4b, 4c, the types of symbols are, for example, 10 types (red 7, white 7, bar, character, cherry, watermelon, bell, replay, miss 1 and miss 2), and these are predetermined. They are arranged in order. In the drawing, the symbols of 21 frames formed on the rotating reel 4a are represented as symbols 4a1, 4a2, ..., 4a21, respectively. Similarly, the symbols of 21 frames formed on the rotating reel 4b are represented as symbols 4b1, 4b2, ..., 4b21, and the symbols of 21 frames formed on the rotating reel 4c are represented as symbols 4c1, 4c2 ,. ing. The number attached to the end of the symbol of each symbol represents the symbol number.

  On the rotating reels 4a, 4b, 4c, the respective symbols are arranged at equal intervals, and the break positions of the symbols are indicated by broken lines in the figure. In the rotary reels 4a, 4b, 4c, a predetermined symbol break position is the origin position 101. The origin position 101 in this example is set to the symbol break position between the symbols 4a1, 4b1, 4c1 which are the first symbol and the symbols 4a21, 4b21, 4c21 which are the 21st symbol, respectively.

  The arrow R in the drawing indicates the rotation direction of the rotary reels 4a, 4b, 4c during steady rotation (during normal rotation). As can be understood from this, the numbers given to the respective symbols represent the order in which the symbols transit during steady rotation, starting from the origin position 101.

Here, in this example, the stepping motors 54a, 54b, 54c and the rotating reels 4a, 4b, 4c are rotated so that each rotation of the stepping motors 54a, 54b, 54c makes 1/63 rotations. The rotation ratio between and is set. In other words, in order to rotate the rotating reels 4a, 4b, 4c once, it is necessary to rotate the stepping motors 54a, 54b, 54c 63 times.
Therefore, in this example, the number of driving steps of the stepping motors 54a, 54b, 54c required to rotate the rotating reels 4a, 4b, 4c once is 8 × 63 = 504.

Since the symbols of 21 frames are formed at equal intervals on the rotating reels 4a, 4b, 4c in this example, the number of steps per symbol is 504 ÷ 21 = 24 steps.
In response to this, a total of 24 positions can be detected as step positions for each symbol. Here, the step position in the symbol can be detected by decrementing the symbol step number (-1) for each timer interrupt by the processing of steps S1512 and S1520 described later in FIG. 33. That is, the number of step positions that can be detected in each symbol is 24 (first step position) to 24 (first step position). At this time, in the process of FIG. 33, when the number of symbol steps = 0, that is, when the final step position of the symbol is reached, the number of symbol steps = “24” is immediately set in the processes of steps S1514 and S1522. Therefore, the 0th step position is synonymous with the 24th step position in the next symbol.

Further, for each symbol, a predetermined step position among the 24 (0) to 1st step positions is defined as a position (stop permission step position) at which the stop of the symbol should be permitted. Specifically, the 7th step position is set as the stop permission step position of the symbol (see FIG. 24). When the rotating reel 4 is stopped, a stop symbol is determined, and the rotating reel 4 is stopped with the stop symbol. At this time, the position at which the rotating reel 4 is stopped does not have to be any step position in the stop symbol, and is 7th. It is set to allow the stop in response to reaching the step position of.

<5. Memory area>

FIG. 13 is an explanatory diagram of a region (memory region) set in the memory of the main control board 40. Specifically, it is an explanatory diagram of areas set in a memory accessible by the CPU 80a, such as the ROM 80b and the RAM 80c.

A first memory area and a second memory area are set in the memory accessible by the CPU 80a. The first memory area is defined as an area for arranging a predetermined program and data used by the CPU 80a in advancing a game operation (game). The second memory area is defined as an area for arranging programs and data that are permitted to be arranged outside the first memory area.
In the present example, the allocation to the second memory area is permitted to be programs and data for taking measures against fraudulent acts (so-called goto). Specifically, for example, it is a program and data for detecting illegal insertion and payout of medals, a program and data for detecting abnormality of the set value vd, random number, and the like.
Each of the first memory area and the second memory area has a control area for storing a program, a data area for storing data used by the program, and various flags and timer values generated in the process of processing by the program. An R / W area (Read / Write area) for rewritably storing the like is set.
It should be noted that the first memory area and the second memory area can hold stored information by a common backup power supply provided on the power supply board 41 even after the power is cut off.

FIG. 14 is an explanatory diagram of the regulations set for the first memory area and the second memory area.
In each of the first and second memory areas, the program in the control area is permitted to refer to and update (record) the data in the R / W area in its own area. On the other hand, in each of the first and second memory areas, the program in the control area is only permitted to refer to the data in the R / W area in the other memory area and is not permitted to be updated. For example, regarding the flag recorded in the R / W area in the second memory area by the program in the second memory area, the program in the first memory area is allowed to refer only and cannot be updated. Can not.
Although illustration is omitted, with respect to the data in the data area, only the program in the same memory area is allowed to refer to. That is, the program in the first memory area refers to the data in the data area in the second memory area, and the program in the second memory area refers to the data in the data area in the first memory area. Is not allowed.

<6. Start processing>

Hereinafter, various processes executed by the CPU 80a of the main control board 40 will be described.
First, with reference to the flow chart of FIG. 15, a start process executed at the time of starting the slot machine (when the power is turned on) will be described.
This start processing is executed by the CPU 80a in response to a reset signal generated when the power is turned on and when the watchdog timer (WDT) in the controller 80 times out. That is, the start process is executed when the controller 80 is activated when the slot machine is powered on and when the controller 80 is restarted when the operation of the controller 80 is delayed for a predetermined time or longer due to some trouble.

  In FIG. 15, the CPU 80a executes a process of setting an internal register in step S101. That is, the value to be set in the built-in register during the start process is read from the ROM 80b and set in the built-in register.

In the subsequent step S102, the CPU 80a sets the stack initial value in the stack pointer, and in step S103 confirms the state (ON / OFF state) of the power interruption signal from the power supply board 41. If the power failure signal is ON, the CPU 80a returns to step S101 to redo the internal register setting and stack pointer setting.
On the other hand, if the power failure signal is OFF, the CPU 80a proceeds to step S104 to set to permit access to the RAM 80c, and then in step S105, is the power failure keyword a predetermined value (eg, “5AA5h”)? Determine whether or not. The power failure keyword is set in the process of step S404 (FIG. 18) described later when power is cut off. The predetermined value of the power failure keyword indicates that the data is surely saved in the RAM 80c at the time of power failure (see step S402 in FIG. 18).

If the power interruption keyword is a predetermined value, the CPU 80a proceeds to step S106 to check the state (ON / OFF state) of the setting key switch 72a. If the setting key switch 72a is OFF, the CPU 80a proceeds to the power restoration processing (FIG. 16) described later.
On the other hand, if the setting key switch 72a is ON, the CPU 80a proceeds to step S107 to determine whether the door (front panel 2) is in the open state based on the detection signal from the door opening sensor 35. If the door is not in the open state, the CPU 80a shifts to power restoration processing.
If the door is in the open state, the CPU 80a proceeds to the setting change processing described later.
As will be understood from the above description, even if the setting key switch 72a is ON in step S106, the setting change process is not performed unless the door is open in step S107. That is, the setting key operation in this case is treated as invalid. In this way, by invalidating the setting key operation when the door is not opened, it is possible to prevent fraudulent acts of falsifying the setting value vd (the same applies to steps S109 and S110 described later).

If the power interruption keyword is not the predetermined value in the previous step S105, the CPU 80a proceeds to step S108 to perform a RAM clearing process, for example, a process of initializing all the storage areas of the RAM 80c. Since the RAM clear is performed in the setting change process (see FIG. 17) at the next power-on, the RAM clear process in step S108 can be omitted.
When the RAM clearing process in step S108 is executed, the CPU 80a proceeds to step S109 to check the state of the setting key switch 72a as in the previous step S106. If the setting key switch 72a is ON, the previous step is performed in step S110. Similar to S107, it is determined whether the door is open. If the door is open, the CPU 80a proceeds to the setting change process.

On the other hand, when the setting key switch 72a is OFF in step S109 and when the door is not in the open state in step S110, the CPU 80a proceeds to step S111 to perform a process of setting a RAM error, and the infinite loop state. Move to. When a RAM error is set in this RAM error setting processing, processing for error notification is performed on the timer interrupt processing side described later. From the infinite loop state, the game can be started by turning on the power again and then setting a new set value vd.

<7. Power recovery process>

FIG. 16 is a flowchart of the power restoration process.
In FIG. 16, the CPU 80a executes a process of clearing the power failure keyword in step S201, and a process of restoring the stack pointer at power failure in step S202. That is, the value of the stack pointer (see step S403 in FIG. 18) stored in the work area of the RAM 80c at the time of power interruption is read out and reset (main setting) to the stack pointer.

  In a succeeding step S203, the CPU 80a determines whether or not the rotating reel 4 is accelerating or rotating. That is, it is determined whether or not at least one of an in-acceleration flag FG2 and a constant-speed rotation flag FG3 (each set in the process of FIG. 33), which will be described later, is “1” indicating that acceleration or constant-speed rotation is in progress. To do. The process of step S203 is sequentially performed for one target rotary reel 4 among the three rotary reels 4 (4a to 4c). If a negative result is obtained in step S205 described later, the target rotating reel 4 is switched.

If the rotating reel 4 is accelerating or rotating in step S203, the CPU 80a sets the reel sensor non-passage flag Fmt and the acceleration preparation flag FG1 in step S204 (“1” indicating that each reel has not passed, After setting "1" indicating that the vehicle is preparing for acceleration, the process proceeds to step S205. The reel sensor non-passage flag Fmt is a flag for indicating whether or not the origin position 101 has not been detected by the index sensor 55 described above. The acceleration preparation flag FG1 is a flag relating to execution of acceleration processing for accelerating the rotary reel 4 from the stopped state, and specifically, indicates whether or not the acceleration processing should be started. It is regarded as a flag. By setting the reel sensor non-passage flag Fmt and the acceleration preparation flag FG1 in step S204 described above, the rotating reel 4 is restarted by the timer interrupt process described later.
On the other hand, if the rotating reel 4 is not accelerating or rotating, the CPU 80a skips step S204 and proceeds to step S205.

  In step S205, the CPU 80a determines whether or not the determination process of step S203 (and the flag setting process of step S204, if necessary) has been executed for all the rotating reels 4, and it must be executed for all the rotating reels 4. If so, the process returns to step S203, and if executed, the process proceeds to step S206.

  In step S206, the CPU 80a executes a process of setting a power return command in a predetermined area of the RAM 80c as a power return command setting process. This power restoration command is a command indicating that the power has been restored to the state when the power was cut off, and the set command is output to the effect control board 42 side in the timer interrupt processing of FIG. 26 described later (see step S1014).

In a succeeding step S207, the CPU 80a performs a process of restoring the register state to the state immediately before the power-off process (FIG. 18) is executed as the all-register restoring process. That is, the value of each register (see step S402) stored in the register save area of the RAM 80c at the time of power interruption is read out, and the process of resetting to each register is performed.
Then, in the subsequent step S208, the CPU 80a sets the interrupt permission, and finishes the power restoration process shown in FIG.
After that, the CPU 80a executes the control program based on the stack pointer and the register after the reset, and as a result, the slot machine returns to the state when the power is turned off.

<8. Setting change process>

FIG. 17 is a flowchart of the setting change process.
In FIG. 17, the CPU 80a executes a RAM clearing process when the setting is changed in step S301. That is, a process of clearing the area (not including the storage area for the setting value vd) defined in the RAM 80c when the setting is changed is performed.
In subsequent step S302, the CPU 80a sets a setting flag indicating whether the setting is being changed (sets "1" indicating that the setting is being changed), and is stored in the RAM 80c in the subsequent step S303. The set value vd that has been set is acquired.

  When the setting value vd is acquired in step S303, the CPU 80a performs a process of clearing the setting value vd to 0 in step S304 if the setting value vd is outside the range of "0" to "5". This is because when the set value vd exceeds "5" due to the set value vd being incremented by 1 in step S309 described later, the set value vd becomes "0" (set to "1"). It is a process to be returned to the corresponding value).

  In a succeeding step S305, the CPU 80a executes a process for displaying the set value vd in 7 segments. That is, for displaying the value (any one of “1” to “6”) corresponding to the current setting value vd on the display (7-segment display) provided on the above-described rotating cylinder setting board 71. Perform processing. The current set value vd referred to here means the set value vd obtained in step S303 and after the processing of step S304.

  In the next step S306, the CPU 80a performs a waiting process (1.49 ms × 2) for two timer interrupts. During this standby processing, interrupt processing is permitted.

In subsequent step S307, the CPU 80a confirms the state (ON / OFF state) of the start lever 17 (start switch). This corresponds to checking whether or not the set value vd has been confirmed.
If the start lever 17 is OFF, the CPU 80a proceeds to step S308 to check the state of the reset switch 72b (ON / OFF state), that is, the presence or absence of a feed operation of the set value vd. If the reset switch 72b is OFF, the step is performed. The process returns to the 2-interrupt standby process of S306.
As a result, the standby process of step S306 is repeated until either the operation of confirming the set value vd by the start lever 17 or the operation of sending the set value vd by the reset button is performed.

  If the reset switch 72b is ON in step S308, the CPU 80a proceeds to step S309 to increment (+1) the set value vd, and then returns to step S304.

  If the start lever 17 is ON in step S307, the CPU 80a proceeds to step S310 to save (store) the current set value vd in a predetermined area of the RAM 82c.

  When the setting value vd is stored in the RAM 82c in step S310, the CPU 80a performs a process of turning on the setting value confirming LED in step S311, that is, turning on an LED provided on the rotating drum setting board 71 for indicating the setting value confirmation. Perform processing.

  Then, in the subsequent step S312, the CPU 80a executes a process for waiting for an operation for ending the change of the set value vd. That is, the state of the setting key switch 72a is confirmed, and if it is ON, the process returns to step S312.

If the setting key switch 72a is OFF, the CPU 80a proceeds to step S313 to set a setting value command. The set value command is a command for notifying the effect control board 42 side of the set value vd stored in the RAM 80c in step S310. The set command is output to the effect control board 42 side in the timer interrupt process (FIG. 26) (step S1014).
The CPU 80a ends the setting change process shown in FIG. 17 in response to the command set process of step S313 being executed.
The CPU 80a shifts to the main process shown in FIG. 19 in response to the completion of the setting change process.

<9. Power-off process>

FIG. 18 is a flowchart of the power-off process.
This power-off process is an interrupt process that occurs in response to the input of a power-off signal (so-called INT interrupt). The interrupt priority is “timer interrupt> INT interrupt”.

  In FIG. 18, the CPU 80a confirms the state of the power-off signal from the power supply board 41 in step S401. When the power-off signal is OFF, the CPU 80a ends the power-off process.

  If the power-off signal is ON, the CPU 80a executes a process of saving the values of all the registers in the register save area in the RAM 80c in step S402, and the stack pointer (see the previous step S102) in the work of the RAM 80c in step S403. It is set in the area, and the above-mentioned predetermined value is set as the power interruption keyword in step S404.

Further, the CPU 80a makes a setting to prohibit access to the RAM 80c in a succeeding step S405, clears all output ports in a step S406, and shifts to an infinite loop state.

<10. Main processing>

19 and 20 are flowcharts of the main process.
The main process is an infinite loop process that is repeatedly executed for each game. In this example, one game period includes at least the period until the rotating reel 4 is rotated and stopped in the stop mode based on the lottery result.

  In the main process, the CPU 80a sets a game state command in step S501. The game state command is a command for notifying the effect control board 42 of the current game state such as the RB state and the RT state.

  In subsequent step S502, the CPU 80a confirms the state (ON / OFF state) of the overflow sensor provided for the auxiliary tank 6, and if the overflow sensor is ON, an error indicating that the stored medal is in the overflow state The flag is set, and the process returns to step S502. That is, as long as it is in the overflow state, the process loops in steps S502 → S503 → S502 ... And the progress of the main process is interrupted.

On the other hand, if the overflow sensor is OFF, the CPU 80a proceeds to step S504, performs various setting processes corresponding to the start of the game as initial settings at the start of the game, and then confirms the re-play flag in step S505. The replay flag is a flag indicating whether or not the player has won (winned) the replay in the immediately preceding game.
If the re-game flag is ON (eg, "1") indicating the winning of the re-game, the CPU 80a proceeds to step S506 to execute the re-game automatic insertion process. This re-game automatic insertion process can be restated as a medal automatic insertion process (pseudo insertion process) for setting a predetermined number of bets.

With reference to the flowchart of FIG. 21, the re-game automatic insertion process of step S506 will be described.
First, in step S601, the CPU 80a executes a process of turning on the re-game display LED. The replay display LED is an LED for notifying the player that the current game is a game as a replay (that is, a replay state).

Next, the CPU 80a acquires the number of inserted medals of the previous game (previous game) in step S602, and executes the process of adding the number of inserted medals of the previous game to the payout signal counter in step S603.
The payout signal counter is a counter used to notify the hall computer of the number of medals paid out to the player according to the winning through the external centralized terminal board 70. Here, the winning includes a replay, and the payout number of medals according to the winning is the number of medals automatically inserted according to the replay (the maximum number of medals: the number of medals: “3” in this example). )) Is also included. Therefore, the number of medals automatically inserted according to the replay is notified to the hall computer as the payout number.
As will be described later, the output of the number of payout medals to the hall computer is performed by outputting the pulse signal of the number of times corresponding to the value of the payout signal counter (insertion and payout signal output processing in step S1007: see FIG. 30). .
Here, in this example, the process of adding the value of the automatic insertion number to the payout signal counter is executed as the process of updating the payout signal counter (S603) corresponding to the replay, but the significance thereof will be described again. .

In step S604 following step S603, the CPU 80a sets the number of inserted medals of the previous game to the number of inserted medals of this game, and ends the automatic insertion process of step S506.
Here, the information of the inserted number of the current game is used when confirming the inserted number of medals in the present game in step S510 (FIG. 19) described later.

The description returns to FIG.
In response to the execution of the automatic loading process in step S506, the CPU 80a advances the process to step S507.
Further, when the CPU 80a determines in the previous step S505 that the re-game flag is not ON (that is, OFF (for example, "0") indicating that the re-game is not won), the automatic insertion of step S506 is performed. The process is passed and the process proceeds to step S507.

  In step S507, the CPU 80a executes interrupt standby processing for a predetermined time (for example, 1.49 ms), and then executes setting confirmation processing in step S508. The setting confirmation process is performed by displaying the current value on the display for confirming the set value vd in response to the reset button being operated while the door is open and the setting key is ON while the slot machine is powered on. This is a process for displaying a value according to the set value vd. Specifically, in the setting confirmation processing, the CPU 80a sets a value according to the current set value vd when the confirmation condition (the door sensor 66, the setting key switch 72a, and the reset switch 72b in this example are ON) is satisfied. Set the information to be displayed on the above display. Specifically, the setting confirmation flag is turned on. In response to the setting confirmation flag being turned on, a process for displaying the set value vd is performed in the LED data creation process (step S1002: see FIG. 27) in the timer interrupt process described later.

  Further, in subsequent step S509, the CPU 80a turns on both the adjustment button valid flag Fas and the throwable flag Fai. The settlement button validity flag Fas is a flag for indicating whether or not the acceptance of the settlement button 14 is valid, and the throwable flag Fai indicates whether or not to accept the insertion of medals through the medal slot 12. It is a flag that represents. The acceptance of the inserted medal and the acceptance of the settlement button 14 are performed by a timer interrupt process described later.

In the next step S510, the CPU 80a determines whether or not the number of inserted medals (the number of bets) is the maximum number of inserted medals (predetermined number: “3” in this example as described above). For example, if the automatic loading process in step S506 is performed, it is determined in step S510 that the maximum number of loaded sheets is reached. Further, even when three medals are inserted through the medal insertion slot 12 or when the max bet button 16 is operated in a state where the number of credits is three or more, the maximum number of inserted medals is determined in step S510. It is determined that
If the CPU 80a determines in step S510 that the number is not the maximum number, the process returns to step S507 and executes the standby process of S507, the confirmation process of S508, and the flag setting process of S509 again. That is, these processes are repeated until it is determined that the maximum number of sheets to be inserted.

On the other hand, when it is determined that the maximum number of sheets to be inserted, the CPU 80a proceeds to step S511 to execute the processing for turning on the start lamp (LED in the LED group 9) described above, and confirms the state of the start lever 17 in step S512. To do. Specifically, the state of the detection signal by the start switch, which is provided on the above-mentioned start switch substrate 62 and is turned on in response to the operation of the start lever 17, is confirmed. The ON edge detection of the detection signal of the start switch is executed by the timer interrupt processing (see S804).
If the detection signal of the start switch is OFF, the CPU 80a returns to step S511, and if the detection signal is ON edge, the random number (random number value generated by the counter circuit 81) has been captured in step S513. Or not.
If the random number acquisition is not completed in step S513, the CPU 80a returns to step S507. That is, even if the ON of the start lever 17 is detected, if the acquisition of the random number is not completed, the process is returned to step S507, and the process is waited until the start lever 17 is turned ON. The random number value of the counter circuit 81 is latched every time the start lever 17 is turned on. The random number value latched when the latest start lever 17 is turned on is used for the winning combination lottery process (S517) described later.

  On the other hand, if the random number acquisition is completed in step S513, the CPU 80a determines in step S514 whether or not a medal is being inserted. It should be noted that whether or not the medal is being inserted is determined by, for example, whether or not one of the first inserted medal sensor 68a (sensor 1) and the second inserted medal sensor 68b (sensor 2) described above is detecting a medal. It can be determined based on crab. If a medal is being inserted, the CPU 80a returns to step S507. That is, even if the start lever 17 is turned on during the insertion of medals, the ON operation is treated as invalid, and the control waits until the start lever 17 is turned on again.

On the other hand, if the medal is not being inserted, the CPU 80a proceeds to step S515 to turn off both the adjustment button valid flag Fas and the insertable flag Fai. By turning off these flags, acceptance of the settlement button 14 and acceptance of inserted medals on the timer interrupt processing side is prohibited.
Further, in the subsequent step S516, the CPU 80a executes a process of setting a game start command for giving a notification corresponding to the start of the game to the effect control board 42 side, and advances the process to step S517 shown in FIG.

  In step S517 shown in FIG. 20, the CPU 80a executes a combination lottery process (symbol lottery process) based on the random number value described above. In this part lottery processing, it is determined whether or not a bonus symbol is won, whether or not a small symbol symbol is won, and whether or not a replay symbol indicating a replay is won, and a control command indicating the determined lottery result. Is set in the transmission buffer in the effect control interface 86, and is transmitted to the effect control board 42 side by the timer interrupt process described later. In addition, as the small role symbols, for example, "cherry symbols" (4a10, 4b3, 4c9), "bell symbols" (4a4, 4b5, 4c3 etc.), "watermelon symbols" (4a9, 4b12, 4c1 etc.) and the like are exemplified. can do.

  In step S518 subsequent to step S517, the CPU 80a executes an instruction monitor output process. As described above, in the present example, the payout display unit 10 is also used as an instruction monitor, and in step S518, the CPU 80a corresponds to the case where the push order combination such as the push order bell or the push order replay is won during the ART. Then, the payout display unit 10 is caused to display the pressing order information of the pressing order combination.

In step S519 following step S518, the CPU 80a sets the insertion number in the insertion signal counter. The throw-in signal counter is a counter used for notifying the hall computer of the number of thrown medals (set bet number) through the external centralized terminal board 70.
The output of the number of inserted medals to the hall computer is performed by outputting the pulse signal of the number of times corresponding to the value of the counter as in the case of the above-described output of the number of paid-out medals (the insertion and payout signal output process of step S1007 is performed. reference).

  In step S520 following step S519, the CPU 80a executes reel effect lottery processing for determining whether or not to execute reel effect. It should be noted that the effects that can be selected in the reel effect lottery process are determined corresponding to the result of the above-mentioned internal lottery process. For example, if a predetermined symbol such as "watermelon symbol" is in an internal winning state, a predetermined reel effect such as "slow effect of rotating extremely slowly in the forward direction and stopping" can be selected based on a predetermined winning probability. Become.

  Further, in the next step S521, the CPU 80a executes a reel effect handling process. In the reel effect handling process, various setting processes for effecting rotation of the rotating reels 4a, 4b, 4c are executed corresponding to the case where the reel effect lottery is won. If the reel effect has not been won, the setting process is passed.

  It should be noted that, when the reel effect is executed, the player can infer that the player has internally won a predetermined symbol corresponding to the type of the reel effect. The player performs a stop operation so that the target symbols are aligned on the stop line from such inference. Only when the reason is correct and the stop timing is appropriate, the internal winning state is put into effect, and the game value is given to the player.

In response to the execution of the reel effect corresponding process, the CPU 80a executes a wait standby process for waiting the elapse of a predetermined wait time such as 4.1 seconds in step S522, and then executes a wait timer (main process) in step S523. In the example, a setting process of 4.1 seconds) is executed. Here, the wait time (4.1 seconds) is the minimum time length that should be left as an interval between games. By thus setting the minimum interval as the interval between games, it is possible to prevent the player from excessively consuming medals.
In the waiting process of step S522, the process waits until the value of the 4.1 second wait timer set by the setting process of step S523 executed one game before becomes “0”. The value of the wait timer is sequentially decremented (subtracted) by a timer interrupt process described later.
Here, 4.1 seconds is an example, and the minimum time interval between games can be appropriately changed.

  In response to executing the setting process of step S523, the CPU 80a performs a process of setting the rotation start command in the transmission buffer of the effect control interface 86 in step S524. The rotation start command is a command for notifying the effect control board 42 side of information corresponding to the start of rotation of the rotary reels 4a to 4c.

In a succeeding step S525, the CPU 80a executes a start setting process for the rotating reels 4a to 4c. The start setting process is a process of setting information required for starting the rotating reels 4a to 4c in the spinning control process (see FIG. 33) in the timer interrupt process. Specifically, in the startup setting process, at least a process of setting the reel sensor non-passage flag Fmt and the acceleration preparation flag FG1 for all the rotating reels 4 (setting “1” indicating ON) is performed.
The acceleration preparation flag FG1 functions as a flag for requesting the timer interrupt process (rotation control process) to start rotating the rotating reel 4.

In step S526 subsequent to step S525, the CPU 80a executes a process of setting stop control data.
Here, the stop control data is data used for determining a sliding piece (see S802 in FIG. 23) described later, and at least the result of the winning combination lottery (combination of symbols to be stopped on the stop line) and the present Is data that is appropriately created (updated) according to which of the first cylinder stop status to the third cylinder stop status. It should be noted that the first stop to the third stop identify the stop number of the rotating reels 4a to 4c in one game.
In this example, the stop control data includes information on the rotating reel 4 (target reel) on which a valid stop button operation (described later) has been performed, and a symbol (a valid stop button operation is performed when the target reel is stopped). The information of (the pattern when broken) is used as the original information, and the number of sliding frames of the target reel is created as data to be specified. Specifically, in this example, the total number of symbols for each unrevolved rotating reel 4 is determined according to the result of the winning combination lottery in step S517 and the current spinning cylinder stop situation (one of the first stop to the third stop). A sliding frame number table that defines the number of sliding frames is created as stop control data.

In the setting process of step S526 (that is, at the time of starting the rotation of each rotating reel 4a), as the above-mentioned sliding frame number table, a table defining the number of sliding frames for all symbols for each of the rotating reels 4a to 4c is created, and created. The sliding frame number table is stored (set) in a predetermined area of the RAM 80c.
As an example, when the winning combination is the first stop = the push order bell of the left reel (the bell which is specified to stop the rotating reel 4a first), the sliding frame number table may be, for example, To create. That is, as the table for the left reel, a table in which the number of sliding frames for each symbol is defined so as to pull in nine bells is created. Regarding the tables of the middle reel (revolving reel 4b) and the right reel (revolving reel 4c), since the pressing sequence has failed, a table is created in which the number of sliding symbols for each symbol is defined so as to draw one winning combination.

In response to the execution of the setting process of step S526, the CPU 80a executes a waiting process of 759.9 ms in step S527. This waiting process corresponds to a timer interrupt waiting process for 510 times.
By setting the acceleration preparation flag FG1 as described above, the starting process (acceleration process) of the rotating reels 4a to 4c is started by the spinning drum control process in the timer interrupt process. The standby process of step S527 functions as a process for waiting until the rotating reels 4a to 4c are in the rotating state by the spinning cylinder control process on the timer interrupt side. The waiting time in step S527 is not limited to the above time.

In step S528 following step S527, the CPU 80a executes a process of waiting until either the reel sensor non-passage flag Fmt or the error flag is turned OFF, and in the next step S529, the stop button LEDs for all reels are executed. A process for turning on (that is, each LED for causing the stop buttons 18a to 18c to emit light) is executed.
Here, in the slot machine, after the rotation reel 4 starts rotating, acceptance of the corresponding stop button 18 is permitted on condition that the origin position 101 of the rotation reel 4 is detected by the corresponding index sensor 55. Is being done. Therefore, if the reel sensor non-passage flag Fmt is ON in step S528, the process does not proceed to the ON processing of the stop button LED in step S529, and waits until the reel sensor non-passage flag Fmt is turned OFF. Has been done.

Further, as understood from the above description, at the time when the process of step S528 is executed, the rotation of the rotary reels 4a to 4c is started (the rotation state before the operation of the stop button 18 is performed). The standby process of step S528 also functions as a process for coping with an error that occurs during the rotation of the rotating reels 4a to 4c. That is, in the standby process of step S528, when the occurrence of an error is recognized during rotation of the rotating reels 4a to 4c (when the error flag is ON), the game operation is performed while maintaining the rotation of the rotating reels 4a to 4c. , And functions as a process for restarting the progress of the game operation in response to the error being released.
Note that at least the main board error (error of the main control board 40), the RWM error (error related to the RAM 80c), the inserted medal error (error related to the medal insertion), and the payout medal not present as the error flags targeted in step S528. There are flags relating to an error, a payout sensor error (an error of the medal payout sensor 76), a wrong prize error, an overflow error, and a door opening error.

In step S530 subsequent to step S529, the CPU 80a executes a stop process. In the stop process of step S530, the operation of the stop button 18 is received, and the process of stopping the corresponding rotating reel 4 in response to the effective stop operation is performed.
The details of the stop processing in step S530 will be described later.

In response to the execution of the stop processing in step S530, the CPU 80a executes the post-stop winning determination processing in step S531. In the winning determination process, it is determined whether or not winning symbols (winning combinations) are arranged on the stop line, and the number of winning coins (the number of medals to be awarded to the player in accordance with the winning prize) is calculated according to the determination result. To do.
In the winning determination process, in order to send a control command (winning information command) indicating the determination result of whether or not the winning symbols are arranged on the stop line to the production control board 42, the transmission of the winning information command in the production control interface 86. The process of setting in the buffer is also performed.

  In step S532 subsequent to step S531, the CPU 80a executes a payout process for winning medals. The details of the payout process will be described later with reference to FIG.

  In response to the execution of the payout process of step S532, the CPU 80a performs the management process of information corresponding to the RB state, the CB (chance bonus) state, and the RT (replay time) state as necessary as the state management process of step S533. Run.

The CPU 80a returns to step S101 shown in FIG. 19 in response to the execution of the state management process of step S533. In this way, the main process is a loop process.

[10-2. Processing for stopping the rotating cylinder on the main processing side]

FIG. 22 is a flowchart of the stop processing of step S530.
First, the CPU 80a executes a standby process for one interrupt in step S701, and performs a stop button determination process in step S702. That is, the presence / absence of a pressing operation for each of the stop buttons 18a to 18c is determined. Then, in subsequent step S703, the CPU 80a determines whether or not a valid stop button operation is performed. That is, it is determined whether or not an effective stop button operation of pressing one of the stop buttons 18a to 18c has been performed.
If the valid stop button operation has not been performed, the CPU 80a returns to step S701. That is, as a result, the system waits until a valid stop button operation is performed.

  On the other hand, if a valid stop button operation has been performed, the CPU 80a executes a press information creation process in step S704. The pressing information is information used when determining a sliding piece in step S802 (see FIG. 23) described later and when updating stop control data in step S809 (see FIG. 23). Reel, push order information, rotation state flag, and each information of symbol stop number are created. The stop target reel is information indicating the rotating reel 4 for which stop is instructed by the stop button operation this time, and the pressing order information is information indicating the pressing order of the stop button 18 in the current game. The rotation state flag is a flag indicating the status of each rotating reel 4 (whether it is rotating or stopped), and the symbol stop number is information indicating the number of rotating reels 4 being stopped.

  In step S705 subsequent to step S704, the CPU 80a executes a barrel stop control process. In this spinning cylinder stop control processing, processing for determining the stop position (determination of the number of sliding frames) for the rotating reel 4 on which the stop button operation has been performed and for stopping the rotating reel 4 at the determined stop position is performed. Be seen.

FIG. 23 is a flowchart of the turning cylinder stop control process of step S705.
In FIG. 23, the CPU 80a confirms in step S801 whether or not it is within a stoppable range, and if it is in an impossible range, executes a process of waiting until the next symbol position.

Here, in this example, when the symbol step position is the symbol step position of the fifth or less, the current symbol is not the symbol at the time of the stop operation (the symbol when the stop operation is performed), and the next The design is used as the design for the stop operation. Therefore, in step S801, the CPU 80a determines whether or not the current symbol step position is the stop position number 24 to 6 (hereinafter referred to as "stop process possible position"), and the stop process possible position. If not, wait until the next symbol step position is reached. If it is the stop processable position, the CPU 80a advances the process to step S802.
The current symbol step position (number of symbol steps) is acquired based on the value of a step counter described later. The value of the step counter is counted by the turning cylinder control process (see FIG. 33) in the timer interrupt process.

For confirmation, the concept of the stop processable position will be described with reference to FIG.
As shown in the figure, in the present example, the step positions of Nos. 24 to 6 are defined as stop processable positions and the step positions of No. 5 to 1 are set as stop process impossible positions. By the process of step S801 described above, if the symbol step position when the stop button operation is detected is the stop processable position, the current symbol is the stop operation symbol, and if it is the stop process impossible position, the current symbol The next symbol is used as the symbol at the time of stop operation.
In this example, when the current step position is the stop processing impossible position of No. 5 to No. 1, the current symbol is not the stop operation symbol and the next symbol is the stop operation symbol, which will be described below. This is because there is a possibility that the process of determining the number of sliding symbols to be performed (S802) may be stopped with an unintended symbol when the processing time is relatively long, and that is to be prevented.

  In this example, the 7th step position is the stop permission step position described above. On the timer interrupt processing side, when the current symbol reaches the stop symbol (the symbol specified by "stop operation symbol + number of sliding pieces") described below, depending on that the step position has reached number 7. It is permitted to perform the brake control (see the turning cylinder control process in FIG. 33).

Returning to FIG. 23, the CPU 80a performs a process for determining the number of sliding symbols in step S802. That is, based on the reel to be stopped (see the pressing information of S704), the current symbol position (symbol at the time of stop operation), and the stop control data (sliding frame number table in this example) stored in the RAM 80c, Determine the number of frames. The symbol specified by adding the determined number of sliding symbols to the symbol number of the symbol at the time of the stop operation is the symbol (stop symbol) for which the target rotating reel 4 is to be stopped.
The current symbol position is acquired based on the value of the symbol counter described later. The value of the symbol counter is also counted by the cylinder control process in the timer interrupt process.

In step S803 following step S802, the CPU 80a executes a process of storing the information of the number of sliding symbols calculated in step S802 in a predetermined area of the RAM 80c, and further adds the number of sliding symbols to the current frame number in step S804. Update the current frame number.
Then, in step S805 subsequent to step S804, the CPU 80a executes a process of storing the scheduled stop position. That is, the information of the current frame number updated in step S804 is stored in a predetermined area of the RAM 80c as information indicating the planned stop position (scheduled stop position for the rotary reel 4 on which the stop button operation has been performed).

  In step S806 following step S805, the CPU 80a turns on the stop request flag FG4 of the target reel (sets "1"). As will be described later, on the condition that the stop request flag FG4 is turned ON, the brake control of the target reel (the rotary reel 4 on which the stop button operation has been performed) is started in the spinning control process in the timer interrupt process. To be done.

  Next, the CPU 80a executes a stop command setting process in step S807. This process is a process of transmitting a stop command for notifying the stop position (stop symbol position) of the target reel to the effect control board 42 side. As the stop position, the information on the planned stop position stored in step S805 is notified.

In step S808 following step S807, the CPU 80a determines whether or not after the first and second stops, that is, whether or not the effective stop button operation this time is the third effective stop button operation in the current game. To do.
After the first and second stops, the CPU 80a proceeds to step S809, executes a process of updating the stop control data used at the next stop based on the stop position and the pressing order, and executes the cylinder rotation stop control process of step S705. To finish.
Here, as the update of the stop control data in step S809, a slide frame number table that defines the number of slide frames for all the symbols is created for the remaining unremoved reel 4 in accordance with the current stop result. .
For example, if the current stop is the first stop and the winning combination is the push order combination, pull nine bells on the table of the rotary reels 4 corresponding to the push order correct answer of the second stop. A table defining the number of sliding symbols for all the symbols is created, and a table defining the number of sliding symbols for all the symbols is created so as to pull in one hand for the table of the rotating reel 4 corresponding to the failure of the pushing order. By storing the table thus created in the RAM 80c, the sliding frame number table (stop control data) stored in the RAM 80c up to then is updated.
In addition, when a winning combination having no concept of the pushing order or a missing part is won, the sliding frame number table may not be updated and the sliding frame number table created at the start of rotation (S526 in FIG. 20) may be used as it is. it can.

  If it is not after the first and second stops in step S808 described above, the CPU 80a passes the update process of step S809 and ends the rotating cylinder stop control process of step S705. That is, if the current stop is the third stop, the next stop in the current game does not exist, and thus the update processing of the stop control data is not performed.

  Here, in this example, regarding the creation (update) of the stop control data used to determine the number of sliding symbols (stop symbol position) for the rotating reel 4 on which the effective stop button operation has been performed, after the first stop, After each of the second stops, after the stop control data to be used at the next stop is created, the acceptance of the valid stop button operation is validated (see S809 and S703), but its significance will be described later. explain.

The description returns to FIG.
The CPU 80a executes the post-stop freeze processing of step S706 in response to the execution of the spinning cylinder stop control processing of step S705, and then determines whether or not all reels are stopped in step S707, that is, the stop button 18a to the stop button 18c. It is determined whether or not a valid stop button operation has been performed for all of the above.
In the freeze process after stop in step S706, it is determined whether or not the freeze effect after stop is won, and only when it is won, the process for realizing the reel effect operation as the freeze effect after stop is performed. Run.

  If it is determined in step S707 that all reels are not stopped, the CPU 80a returns to step S701. As a result, a process for waiting for a valid stop button operation is performed on the spinning reel 4 for which a valid stop button operation has not been performed.

  On the other hand, if it is determined that all reels are stopped, the CPU 80a proceeds to step S708 to execute processing for clearing the instruction monitor display. The instruction monitor display is started in response to the winning of the push combination in the previous step S518 (see FIG. 20), and the CPU 80a performs a process for clearing the instruction monitor display in step S708.

  In response to the execution of the clear process in step S708, the CPU 80a determines in step S709 whether the all stop buttons are OFF, that is, whether all the stop buttons 18a to 18c are in the non-operation state (non-pressed state), and the all stop is performed. If the button is not turned off, the process of step S709 is executed again.

  On the other hand, if the all stop button is OFF, the CPU 80a proceeds to step S710 to determine whether or not all reels have been stopped. Whether or not all the spinning reels 4 have been stopped can be determined by whether or not the reel status of each spinning reel 4 has been cleared. The reel status here means at least the states of the acceleration preparation flag FG1, the acceleration flag FG2, the low speed rotation flag FG3, the stop request flag FG4, and the stop operation flag FG5. The reel status of each rotating reel 4 is cleared according to the completion of the rotation stop by the process of step S1531 in FIG. Therefore, in step S710, it is determined whether or not the reel status of each rotating reel 4 is cleared, that is, the acceleration preparation flag FG1, the acceleration flag FG2, the low speed rotation flag FG3, the stop request flag FG4, and the stop operation flag. By determining whether or not all FG5 are OFF (for example, “0”), it is determined whether or not all reels have been stopped.

  If all reels have not been stopped in step S710, the CPU 80a returns to step S709, and if all reels have been stopped, the stop process of step S530 ends. That is, the stop process of step S530 is completed on condition that the all stop button is OFF and all reels are completely stopped.

Here, as can be understood from the above description, in the main process of this example, when the effective stop button operation is performed (S703: Yes), the number of sliding frames of the rotating reel 4 on which the operation is performed is changed. After the determination (S802) and the ON processing of the stop request flag FG4 (S806) are executed, and the rotating reel 4 is not the third stop reel (S707: No), the next valid stop button operation is accepted. I am trying to enable.
At this time, there is a process of waiting for the rotation reel 4 to be stopped after the valid stop button operation is performed until the acceptance of the next valid stop button operation is validated after the stop request flag is turned on. do not do. That is, in the main processing in this example, after determining the number of sliding symbols of the rotating reel 4 on which the effective stop button operation has been performed (that is, determining the stop symbol position), without waiting for the rotation reel 4 to stop, The valid acceptance of the stop button operation of is enabled.

  In response to the stop request flag FG4 being turned on at the main processing side, the drive control of the stepping motor 54 for stopping rotation is performed in the spinning drum control processing of FIG. As a result, the rotation of the target reel is stopped.

  Here, as described above, in this example, regarding the creation (update) of the stop control data used for determining the number of sliding symbols, the stop control used at the next stop after the first stop and after the second stop, respectively. After creating the usage data, acceptance of valid stop button operations is to be validated. In other words, before the next effective stop button operation is performed, the stop control data used at the next stop is created in advance.

  In this example, when the rotating reel 4 is stopped, it is determined whether or not the stop processing is possible position (see FIG. 24), and when the stop processing is possible position, the “stop operation symbol = current symbol” is the stop operation symbol. The number of sliding pieces is determined based on, and when it is not the stop processing possible position, the number of sliding pieces is determined based on the stop operation symbol as "a symbol at the time of stop operation = a symbol next to the current symbol". (See S801 and S802).

  On the other hand, the rotation of the rotating reel 4 is performed so as to proceed step by step for each timer interrupt in the turning cylinder control process (FIG. 33) of the timer interrupt process as described later. Therefore, if the timer interrupt occurs before the number of sliding symbols is determined after the stop operation symbol is determined, the step position and the actual step position referred to when the stop operation symbol is determined Since there is a divergence, and since it is actually a step position in the unstoppable range, the next symbol should be the symbol at the time of stop operation, but the current symbol is the symbol at the time of stop operation and the number of sliding pieces is A situation may occur in which the decision is made. That is, as a result, the target reel may not be stopped at the proper stop position.

  Regarding the creation (update) of the stop control data, the processing time may change depending on the type of winning combination and the game situation such as the spinning stop state, and may take a maximum of 10 ms or more. Therefore, if it is assumed that the stop control data creation process is performed after the stop button operation, multiple timer interrupts may occur between the stop button operation and the determination of the number of sliding frames. The time symbol and the original stop operation symbol may deviate from each other, and the target reel may not be stopped at an appropriate stop position.

  Therefore, in this example, after the first stop and after the second stop, after the stop control data used for the next stop is created, the acceptance of the valid stop button operation is validated. In other words, after determining the number of sliding symbols (stop symbol position) for the rotary reel 4 on which the effective stop button operation has been performed, after creating stop control data for the next rotary reel 4, Acceptance of valid stop button operations shall be validated.

Thereby, the second stop, the stop control data used to determine the number of sliding pieces of the third stop, it is possible to create in advance before the stop button operation, the actual stop operation pattern as described above It is possible to prevent the occurrence of a discrepancy between the original and the symbol at the time of the stop operation.
Therefore, the target reel can be stopped at an appropriate stop position, and the accuracy of the spinning cylinder stop control can be improved.

[10-3. Payment processing of prize medals]

FIG. 25 is an explanatory diagram of a payout medal payout process (step S532).
First, in step S901, the CPU 80a determines whether or not the winning number is "0". As described above, the winning number is set in the winning determination process of step S531. If the winning number is "0", the CPU 80a finishes the payout process of the winning medals.

If the winning number is not "0", the CPU 80a proceeds to step S902 to determine whether or not an error is occurring. The errors targeted in step S902 are various errors that can be detected by the slot machine, and are at least the main board error, RWM error, throwing medal error, payout medal error, payout sensor error, and non-winning prize error. Including, overflow error, door open error.
If it is determined in step S902 that an error is occurring, the CPU 80a executes the determination process of step S902 again. That is, the progress of the main process (the progress of the game) is suspended until the error is canceled.

  On the other hand, if it is determined that it is not in an error, the CPU 80a proceeds to step S903, and executes a process of setting a payout start command for notifying the effect control board 42 side of the start of payout in the transmission buffer.

  In a succeeding step S904, the CPU 80a performs execution waiting processing of timer interrupt processing. This waiting process is intended to prevent the timer interrupt process from entering during the credit addition process described below.

In response to the execution of the waiting process in step S904, the CPU 80a determines in step S905 whether the credit value is MAX (maximum value: “50” in this example). If the credit value is not MAX, the CPU 80a increments the credit value (+1), increments the value of the payout signal counter, and increments the payout display number by the processes of steps S906, S907, and S908.
Then, the CPU 80a performs a process of waiting for 80 ms in the next step S909, and then, in step S910, a process of decrementing (-1) the value of the winning number.

Here, in step S907, the payout signal counter is a counter used to notify the payout number to the hall computer as described above. In the main processing, the value of the payout signal counter is sequentially incremented within the range of the number of winning coins as described above, while in the "insertion and payout signal output processing" (step S1007) on the timer interrupt processing side, which will be described later, the payout signal counter Corresponding to the case where the value is other than "0", the processing for decrementing the value of the payout signal counter and outputting the payout signal bit (pulse signal) to the hall computer is performed. In the hall computer, it is possible to manage the number of payouts of the slot machine based on the number of times the payout signal bit is output.
In step S908, the payout display number means the payout number in the current game to be displayed on the payout display unit 10 described above. In this example, the number display on the payout display unit 10 is performed in a mode in which the value is incremented each time the winning number is given in units of one, so that the value of the payout display number is sequentially incremented in step S908. ing. Although illustration is omitted, the CPU 80a resets the value of the payout display number to "0" at a predetermined timing until the next game starts, such as the timing of inserting a medal or turning on the start lever 17 (that is, the payout display). The number display on the copy 10 is sequentially incremented from "0" to "winning number" and then cleared by the next game start timing). It should be noted that the value of the payout display number may be reset to 0 according to the lapse of a predetermined time even if the medal insertion or the ON operation of the start lever 17 is not performed.

  The standby process of step S909 is a process of determining the update interval of the payout signal counter until the credit value reaches MAX (that is, the winning number is added to the credit). Regarding the update interval, 80 ms is only an example, and the update interval is not limited to this value. As will be described later, the output period of the payout signal (payout signal bit) is 125.16 ms in this example (FIG. 31), so the update interval of the payout signal counter defined in step S909 may be set shorter than this. desirable.

  In response to the value of the winning number being decremented in step S910, the CPU 80a determines in step S911 whether or not the winning number is "0". If the value of the winning number is not "0", the CPU 80a returns to the previous step S904. That is, if the medal-giving process for the number of winning coins is not completed, the execution process of the timer interrupt process is executed, and then the credit MAX determination process of step S905 is executed again. If the credit value is not MAX, the above-described steps S906 to S911 are executed again.

  On the other hand, if the value of the winning number is “0” in step S911, the CPU 80a executes a process of setting a payout end command for notifying the effect control board 42 side of the payout end in the transmission buffer in step S915, and wins the prize. The medal payout process (S532) ends.

If the credit value is MAX in the previous step S905, the CPU 80a turns on the payout request in step S912.
Here, when the credit value is MAX, the medal payout (medal payout via the medal discharge port 20) using the medal payout device 5 is performed instead of credit addition. The control process for the medal payout using the medal payout device 5 is executed on the timer interrupt processing side (see the medal payout process of FIG. 29), and the payout request requests the execution of the control process. is there.

  In a succeeding step S913, the CPU 80a executes an execution waiting process of the timer interrupt process, and determines in a step S914 whether or not the value of the winning number is "0". As will be understood from the description below, in the medal payout process in the timer interruption process, the value of the number of winning coins is decremented every time one medal is paid out.

If the value of the winning number is not "0" in step S914, the CPU 80a returns to step S912.
On the other hand, if the value of the number of winning coins is "0", the CPU 80a executes the command setting process of the previous step S915, and finishes the payout medal payout process.

<11. Timer interrupt processing>
[11-1. Timer interrupt processing]

Next, the timer interrupt process started every predetermined time (every 1.49 ms in this example) will be described.
FIG. 26 is a flowchart of timer interrupt processing.
In FIG. 26, the CPU 80a first saves the register value in step S1001 (register save process), and then executes the LED data creation process in step S1002. The LED data creation process is performed by a 7-segment LED as the payout display unit 10 and the stored number display unit 11 mounted on the game display board 61, various LEDs provided as the LED group 9, that is, the number of inserted medals. LED, indicating the re-play state, LED as a start lamp, LED indicating the acceptance status (insertion permission / non-permission of insertion) of medals, and information display by 7-segment LED for displaying the set value This is the process of creating the data required to realize. The details of the creation process will be described later with reference to FIG.

  In a succeeding step S1003, the CPU 80a executes, as a command creating process, a process of creating various command data and setting it in the transmission buffer of the effect control interface 86. The set command is output to the effect control board 42 side in an output process (S1014) described later.

Further, in the next step S1004, the CPU 80a performs an input port reading process. That is, the data of the input port that receives various switch signals and sensor signals is acquired and stored in a predetermined area of the RAM 80c, for example. In addition, the sensor signal includes the selector sensor 67, the inserted medal-related sensor 68, each index sensor 55 of the first body index sensor 55a, the second body index sensor 55b, and the third body index sensor 55c, the door sensor 66, and the like. The detection signal from is included.
In the reading process of step S1004, data of ON edges and OFF edges of switch signals and sensor signals are created and stored in the RAM 80c.

  In a succeeding step S1005, the CPU 80a subtracts a value of a predetermined timer such as a demo timer or a weight timer as a timer subtracting process, and executes a medal payout process in a step S1006. The medal payout process is a process for paying out medals in response to a payment request (turned on in step S1012 described later based on the operation of the payment button 14) or a payout request (see step S912 above) described later. However, details will be described later with reference to FIG.

  In response to the execution of the medal payout process in step S1006, the CPU 80a executes the insertion and payout signal output process in step S1007. This insertion / payout signal output process is a process for outputting information (insertion signal bit, payout signal bit) for notifying the number of inserted medals and the number of medals in the slot machine to the hole computer. Will be described later with reference to FIG.

  The error release determination process of step S1008 subsequent to step S1007 is for determining whether or not the error state has been released in response to the error occurrence with respect to various errors such as an inserted medal error, a payout sensor error, and a door opening error. Processing. The details of the error cancellation determination process will be described later with reference to FIG.

  In response to the execution of the error cancellation determination process of step S1008, the CPU 80a performs an error flag setting process and an external output terminal output process according to the error type in step S1009 and subsequent step S1010, respectively. Specifically, in step S1009, the CPU 80a sets the door opening error flag when the occurrence error is the door opening error and outputs a signal through the corresponding external output terminal of the external centralized terminal board 70. The process of is executed. Further, in step S1010, the CPU 80a sets an error flag corresponding to any of the main board error, the RWM error, the inserted medal error, the payout sensor error, and the non-winning prize error, and the external concentration is performed. A process for outputting a signal via the corresponding external output terminal of the terminal board 70 is executed.

  In response to the execution of the process of step S1010, the CPU 80a executes the medal insertion process in step S1011. The medal insertion process is a process of updating the number of inserted medals and the value of credits according to the insertion of medals through the medal insertion slot 12 and the operation of the max bet button 16.

  In a succeeding step S1012, the CPU 80a executes a stored medal settlement process. The accumulated medal settlement process is a process of determining various conditions such as the operation of the settlement button 14 and turning on the settlement request.

  In step S1013 subsequent to step S1012, the CPU 80a executes a barrel control process. In the turning cylinder control processing, processing relating to drive control of the stepping motor 54 for rotating / stopping the rotating reel 4 is performed, and details thereof will be described later with reference to FIG.

  In response to the execution of the barrel control processing in step S1013, the CPU 80a executes output processing in step S1014. In this output process, a process for outputting various set data to a corresponding output destination is performed. The data to be output also includes the various commands described above (commands for the effect control board 42) and data for driving the stepping motor 54 (excitation data φ1 to φ4 described above).

In response to the execution of the output process of step S1014, the CPU 80a executes the process of restoring the register value saved in the process of step S1001 as the register restoration process of step S1015, and ends the timer interrupt process.

[11-2. LED display data creation processing]

FIG. 27 is a flowchart of the LED display data creation processing (S1002).
As described above, the LED display data creation process is performed by the payout display unit 10, the respective 7-segment LEDs as the stored number display unit 11, the LED indicating the number of inserted medals provided as the LED group 9, and the replay state. Is a process for creating data for displaying an LED for indicating, an LED as a start lamp, an LED for permitting / not permitting insertion of medals, and a 7-segment LED for displaying a set value.

In the present example, these LEDs are lighting-controlled by so-called dynamic control. Specifically, in this example, the first-digit 7-segment LED (hereinafter “payout number first-digit”), the second-digit 7-segment LED (hereinafter “payout number second-digit”) in the payout display unit 10, the storage First-segment 7-segment LED (hereinafter “credit first-digit”), second-digit 7-segment LED (hereinafter “credit second-digit”) in the number display portion 11, and three LEDs indicating the number of inserted medals (hereinafter "Insert number display 1 to 3"), LED indicating re-play state (hereinafter "re-game"), LED as start lamp (hereinafter "start LED"), LED indicating permission / non-permission of medal insertion (hereinafter “INSERT”) and a 7-segment LED (hereinafter “setting display”) for displaying the set value are classified as common 0 to common 6 as follows.

Common 0 ... 1st digit of payout number Common 1 ... 2nd digit of payout number Common 2 ... 1st digit of credit Common 3 ... 2nd digit of credit Common 4 ... Display of number of input 1-3
Common 5 ... INSERT, replay, start LED
Common 6: Setting display

Then, a control method is adopted in which the display data is commonly output to the commons 0 to 6 while sequentially turning on the commons 0 to 6 in the timer interrupt cycle. That is, only the common LED that is turned on is controlled to light according to the commonly output display data.

Based on the above premise, the process of FIG. 27 will be described.
In FIG. 27, the CPU 80a first determines in step S1101 whether an error is occurring. If there is an error, the CPU 80a sets an error display code corresponding to the error type in the set area for displaying the number of payouts in the work of the RAM 82c in step S1102, and proceeds to step S1103.
On the other hand, if the error is not occurring, the CPU 80a passes the setting process of step S1102 and proceeds to step S1103.

  In step S1103, the CPU 80a sets the data designating the common this time in a predetermined area (common designation data set area) in the work of the RAM 82c. That is, for example, if the common to be subject to the lighting control this time is the common 0, the data for designating the common 0 as the current common is set.

In subsequent step S1104, the CPU 80a sets the output data corresponding to the current common number in a predetermined area (output data set area) in the work of the RAM 82c.
If the common number this time is common 0 or common 1 (the first or second digit of the number of payouts) and the result of the determination in step S1101 is that an error is occurring, the setting process of step S1104 is performed. Then, the output data corresponding to the error display code set in the previous step S1102 is set.

Further, in the next step S1105, the CPU 80a confirms the state of the setting confirmation flag (see previous step S508). If the setting confirmation flag is ON, the process proceeds to step S1106, and the output corresponding to the current set value vd The data is set in the output data set area in the work of the RAM 82c, and the LED data creation processing is completed.
On the other hand, if the setting confirmation flag is OFF, the CPU 80a passes the process of step S1106 and ends the LED data creation process.

  The signal output to the LED side based on the common designation data and the output data (display control data) set on the work in the above processing is performed by the output processing (step S1014) shown in FIG.

Here, when an error occurs, an error display (error notification) using the 7-segment LED as the first digit and second digit of the payout number is performed based on the above-described LED data creation processing. At this time, detection of an error (detection of an ON edge of a detection signal) is executed by timer interrupt processing (see step S1004 “input port reading processing”), and timer interrupt processing (LED data) is also performed as error notification according to error detection. The creation process) is performed. Therefore, the error notification is immediately executed when an error occurs.

[11-3. Error cancellation judgment processing]

FIG. 28 is a flowchart of the error cancellation determination process (S1008).
In FIG. 28, the CPU 80a determines in step S1201 whether or not an error is occurring based on the error flag. If there is no error, the CPU 80a ends the error cancellation determination process.

On the other hand, if there is an error, the CPU 80a determines in step S1202 whether or not the error has been canceled. As described above, the types of errors include a main board error, an RWM error, an inserted medal error, a payout medal error, a payout sensor error, a non-win prize error, an overflow error, and a door opening error. In step S1202, error cancellation determination is performed on these errors based on the following cancellation conditions.

Main board error ... Replacement of main control board 40 RWM error ... Execute setting change processing (FIG. 17) Inserted medal error ... Reset switch 72b is turned on
No payout medal error ... Reset switch 72b is turned on, and door sensor 66 (detection of the above-described cancellation operation)
Discharge sensor error: Reset switch 72b is turned on
Illegal winning error ... ON of the reset switch 72b
Overflow error: The reset switch 72b is turned on, and the door sensor 66 (detection of the above-described cancellation operation).
Door open error ... Door sensor 66 (detection of the cancel release operation described above)

Regarding the main board error and the RWM error, it is impossible to cancel the error based on the reset switch 72b and the door sensor 66.

  If the error is not canceled in step S1202, the CPU 80a ends the error cancellation determination process.

  On the other hand, if the error is released, the CPU 80a executes a process for clearing the error display in step S1203. Specifically, the processing for clearing (for example, not lighting) the error display using the 7-segment LED as the first digit of the payout number and the second digit of the payout number is executed.

In the subsequent step S1204, the CPU 80a executes a process of clearing the error flag, and in a succeeding step S1205, executes a process for returning the payout amount display, and ends the error cancellation determination process.

[11-4. Medal payout processing]

FIG. 29 is a flowchart of the medal payout process (S1006).
The medal payout process is performed by the payout motor in the medal payout device 5 in response to the above-mentioned payout request (request for medal payout due to winning: see FIG. 25) or settlement request (request for medal payout according to operation of the settlement button 14). This is a process for driving and controlling 75.
Here, the payout request is turned ON corresponding to the case where the credit is MAX in the "winning medal payout process (FIG. 25)" of step S532 described above (see step S912). The settlement request is turned on in the "stored medal settlement process (FIG. 26)" in step S1012 in response to the operation of the settlement button 14.

  In FIG. 29, the CPU 80a determines in step S1301 whether or not the medal sensor passing timer = “0”. The medal sensor passing timer is a timer for measuring a time for detecting an error in which the above-mentioned medal payout sensor 76 continues to be turned on, and step S1312 to be described later in response to the medal payout sensor 76 being turned on. The predetermined value is set with. The initial value of the medal sensor passing timer is "0". Therefore, the medal sensor passing timer is "0" before the payout motor 75 is driven in response to the payout request or the settlement request.

If the medal sensor passing timer = “0”, the CPU 80a proceeds to step S1302 to determine whether the payout request or the settlement request is ON. If the payout request or the settlement request is ON, in step S1303. It is determined whether or not there is an error (other than a door error). That is, it is determined whether any of the various errors except the door error is occurring.
When determining in step S1303 that the error is not occurring, the CPU 80a proceeds to step S1305, and confirms whether the medal payout sensor 76 is ON or OFF. At the time when it is determined that the payout request or the settlement request is ON, the payout control signal (a signal for instructing the driving of the payout motor 75), which will be described later, has not been turned ON, so the medal payout sensor 76 is OFF. Is.

  When the medal payout sensor 76 is OFF in step S1305, the CPU 80a proceeds to step S1306 and confirms whether the payout busy flag Fbe is ON or OFF. Since the payout busy flag Fbe is a flag that is turned on in conjunction with turning on of the payout control signal (see step S1307), the payout busy flag Fbe is OFF in the timer interrupt immediately after the payout request or the settlement request is changed to ON. ..

When the payout busy flag Fbe is OFF in step S1306, the CPU 80a turns on the payout control signal and turns on the payout busy flag Fbe in step S1307. Then, in a succeeding step S1308, a predetermined value (the number of timer interrupts corresponding to 2.5 seconds in this example) is set in the hopper no-medal timer, and the process proceeds to step S1309.
The hopper medal-less timer is a timer for measuring the time during which the payout control signal is turned ON and the payout motor 75 is driven, but the medal is not paid out. It functions as a timer to detect the absence. Specifically, as will be described below, the value of the hopper medal-less timer is consumed to "0", so that the payout medal-less error is set (see step S1311).

  When the payout busy flag Fbe is ON in step S1306, the CPU 80a passes the above steps S1307 and S1308 and proceeds to step S1309.

In step S1309, the CPU 80a decrements (-1) the value of the hopper medal-less timer, and in the following step S1310, it is determined whether or not the hopper medal-less timer = "0". If the timer without hopper medal is not "0", the CPU 80a finishes the medal payout process.
On the other hand, if the hopper medal-less timer = “0”, the CPU 80a sets a payout medal-less error in step S1311.

In response to setting the payout medal absence error in step S1311, the CPU 80a turns off the payout control signal in step S1326, turns off the payout busy flag Fbe in step S1327, and clears the medal sensor passing timer in step S1328. Finish the medal payout process.
In the medal payout process executed by the timer interrupt after the payout medal absence error is set, the process goes through steps S1301 → S1302 → S1303, and it is determined that there is an error in step S1303. Therefore, the CPU 80a executes step S1304. Check whether the payout busy flag Fbe is ON or OFF. Since the payout busy flag Fbe is turned off in response to the setting of the payout medal absence error as described above (S1327), it is determined that the payout busy flag Fbe is OFF in step S1304, and the process proceeds to step S1326. . As understood from this point, after the payout medal absence error is set, the process for driving the payout motor 75 is passed, and the medal payout process is stopped.
If the payout busy flag Fbe is ON in step S1304, the CPU 80a advances the process to step S1305.

Although it has been described above that the payout control signal is turned on in response to the payout request or the settlement request (S1307), when one coin is paid out by the payout motor 75 in response to the turning on of the payout control signal, the medal payout is performed. The sensor 76 is turned on.
When it is determined in step S1305 that the medal payout sensor 76 is ON, the CPU 80a proceeds to step S1312 and sets a predetermined value (a timer interrupt number corresponding to 98.34 ms in this example) in the medal sensor passing timer, and then in step S1313. Proceed to.
In step S1313, the CPU 80a confirms ON / OFF of the medal payout sensor 76 (that is, confirms whether the payout medal is passing through the sensor / passing is completed). If the medal payout sensor 76 is ON (passing), the process proceeds to step S1323. Proceed.

  Here, by setting a predetermined value in the medal sensor passing timer, it is determined in the previous step S1301 that the medal sensor passing timer is not "0" in the medal payout process executed by the subsequent timer interruption. The process proceeds to step S1313. At this time, if the medal payout sensor 76 continues to be in the ON state, the process proceeds to step S1323.

The processes of steps S1323 to S1325 are processes for detecting an error in which the medal payout sensor 76 continues to be turned on for a predetermined time or longer.
Specifically, the CPU 80a decrements (-1) the value of the medal sensor passing timer in step S1323, and determines whether or not the medal sensor passing timer = "0" in the following step S1324. If the medal sensor passing timer = “0”, a payout sensor error is set in step S1325, and the process proceeds to step S1326 described above.
In this case as well, the flow of processing after the error is set is the same as the flow after the above-mentioned payout medal-less error is set, and therefore duplicated description will be omitted.

  On the other hand, if the timer during passage of the medal sensor is not "0", the CPU 80a finishes the medal payout process. That is, while the ON duration of the medal payout sensor 76 is within the normal range, the error setting process of step S1325 is not executed, and at the next timer interruption, if the medal payout sensor 76 is still ON, the process proceeds to S1301. → S1313 → S1323 → S1324, and it is determined again whether the value of the medal sensor passing timer after subtraction is “0”. With such a processing flow, the ON duration of the medal payout sensor 76 (the time during which the medal is being detected) is monitored.

When the medal payout sensor 76 has no abnormality and the payout medal has passed through the medal payout sensor 76, it is confirmed that the medal payout sensor 76 is OFF in the previous step S1313, and the process proceeds to step S1314.
The processing of steps S1314 to S1321 is the case where the request type is a payout request (when the credit is MAX and the winning medal is paid out from the medal payout device 5), and when it is a payment request (in response to the operation of the payment button 14). In the case of paying out from the medal payout device 5), the value to be updated according to the payout of medals is updated.
First, in step S1314, the CPU 80a determines whether or not the request confirmed in step S1302 is a payout request. If it is a payout request, the CPU 80a advances the process to step S1315, and if it is not a payout request (that is, if it is a settlement request), advances the process to step S1318.

  In step S1315, the CPU 80a increments the value of the payout signal counter, increments the value of the payout display number, and decrements the value of the winning number. The processes of incrementing the value of the payout signal counter, incrementing the value of the payout display number, and decrementing the value of the winning number are the same as the processes of steps S907, S908, and S910 in FIG. 25. Therefore, duplicate explanation is avoided.

In response to executing the process of step S1315, the CPU 80a determines in step S1316 whether or not the payout is completed. Specifically, it is determined whether or not the number of winning coins = “0”.
If the payout has not ended, the CPU 80a proceeds to step S1320 to determine whether there is an error (other than a door error). If not, the payout busy flag Fbe is turned off in step S1327, and the medal sensor passing timer in step S1328. After clearing 0, the medal payout process ends.
In this manner, when one medal is paid out and the corresponding value is updated, the payout busy flag Fbe is turned off and the medal sensor passing timer is cleared. Accordingly, in the next timer interrupt, the process proceeds to steps S1301 → S1302 → S1303 → S1305 → S1306, the payout busy flag Fbe is determined to be OFF in S1306, and the payout control signal and the payout busy flag Fbe are turned ON in S1307. To be done. As a result, the payout of medals and the update of the corresponding value in step S1315 are repeated until the winning number becomes "0".

  Here, with respect to the respective values of the payout signal counter, the payout display number, and the winning number, which are updated in step S1315, these update cycles match the cycle in which medals pass through the medal payout sensor 76 (steps S1314 → S1315). reference). That is, the payout signal counter, the payout display number, and the winning number are updated by 1 each time one medal is paid out.

  If it is determined in step S1320 that an error is occurring, the process proceeds to step S1326. Since the flow of processing after the process proceeds to step S1326 according to the fact that an error is occurring in this way, duplicated description will be omitted.

On the other hand, if the payout is completed in step S1316, the CPU 80a turns off the payout request in step S1317, and proceeds to step S1326.
As described above, the payout request is turned off and the process proceeds to step S1326, so that in the next timer interrupt, the process proceeds from step S1301 to S1302, and it is determined in step S1302 that the payout request or the settlement request is not ON. Then, the CPU 80a advances the process to step S1322, and confirms whether the medal payout sensor 76 is ON or OFF.
If the medal payout sensor 76 is ON in step S1322 (that is, the medal payout sensor 76 is ON while the payout request and the settlement request are OFF), the CPU 80a proceeds to step S1325 and sets a payout sensor error. , And advances the processing to step S1326.
On the other hand, if the medal payout sensor 76 is OFF in step S1322, the CPU 80a advances the process to step S1326 without setting a payout sensor error. That is, in this case, in the subsequent timer interruption, the processing is executed in steps S1301 → S1302 → S1322 → S1326 to S1328 until the payout request or the settlement request is turned ON.

When it is determined in the previous step S1314 that the request is not the payout request (that is, when the request is a settlement request), the CPU 80a decrements (-1) the value of the credit or the inserted number in step S1318. That is, for example, if the inserted number ≠ “0”, the value of the inserted number is decremented, and if the inserted number = “0”, the value of the credit is decremented.
It should be noted that the number of coins inserted by the re-game is not settled, and therefore the number of coins inserted is not decremented even after the number of coins inserted is "0" after the re-game.

  In step S1319 following step S1318, the CPU 80a determines whether or not the settlement has been completed, that is, whether or not the settlement of the number of medals that can be settled has been completed. If the settlement has not ended, the CPU 80a advances the process to step S1320 described above. The flow of each processing when it is determined that an error is occurring or when it is determined that an error is not occurring in step S1320 has already been described, and thus a duplicated description will be avoided. If it is not determined in S1320 that there is an error, in the case of a settlement request, the payout of medals and the update of the corresponding value in step S1318 are repeated until the settlement is completed.

When it is determined in step S1319 that the settlement has ended, the CPU 80a turns off the settlement request and sets the settlement end command in step S1321, and advances the processing to step S1326. That is, even when the payout by settlement is completed, thereafter, the processing is executed in steps S1301 → S1302 → S1322 → S1326 to S1328 until the payout request or the settlement request is turned ON.
The settlement completion command is a command for notifying the effect control board 42 side that at least the payout processing by settlement has been completed.

[11-5. Input and output signal output processing]

FIG. 30 is a flow chart of the input and payout signal output processing (S1007).
This input / output signal output processing is processing for causing the hall computer to output the input signal or the output signal through the external centralized terminal board 70 according to the values of the input signal counter or the output signal counter described above.
As can be understood from the above description, the insertion signal counter is a counter whose value is updated according to the insertion of medals, and is the number of inserted medals (which is set in step S519 (see FIG. 20) described above for each game. The value is set according to the bet number).
The payout signal counter is a counter whose value is updated according to the number of winning prizes and the number of automatically inserted replay games. The update of the payout signal counter according to the number of winning coins is performed in the above-described step S907 (when the credit is less than MAX: refer to FIG. 25) and step S1315 (when the credit is MAX: refer to FIG. 25 and FIG. 29). The update of the insertion signal counter according to the automatic insertion number of re-games is performed in step S603 (see FIG. 21) described above.
In the input and payout signal output processing in step S1007, the input signal bit and the payout signal bit are output while the number of times corresponding to the values of the input signal counter and the payout signal counter, the input signal bit by the pulse signal, and the payout signal bit are output. The value of the input signal counter and the value of the payout signal counter are decremented each time.

In this example, a timer interrupt counter (a counter whose value is updated for each timer interrupt) is used to output the input signal and the payout signal.
As shown in FIG. 31, in this example, by using the timer interrupt counter, the input signal and the output signal are oscillation signals which repeat OFF / ON with 84 interrupts (1.49 ms × 84 = 125.16 ms) as one cycle. Output. The ON period of the oscillation signal is the input signal bit or the payout signal bit, and the ON duty of the oscillation signal is 50% in this example. Therefore, the output period of the input signal bit and the payout signal bit is a period of 42 interrupts (1.49 ms × 42 = 62.58 ms).
Here, in this example, both the input signal and the output signal are signals that are turned off during the first half period (timer interrupt counter = 83 to 42) in one cycle.

Based on the above assumptions, the process of FIG. 30 will be described.
First, the CPU 80a executes a process of decrementing (-1) the timer interrupt counter in step S1401, and determines whether the timer interrupt counter is "-1" or not in subsequent step S1402. The initial value of the timer interrupt counter is "0", and therefore, in the timer interrupt processing executed for the first time, the determination result that the timer interrupt counter is "-1" is obtained in step S1402.

  If the timer interrupt counter is "-1", the CPU 80a proceeds to step S1403 to set the initial value "83" to the timer interrupt counter, and clears the insertion signal and the payout signal in the following step S1404 (that is, OFF). The processing of clearing to “0”) is executed, and the input and payout signal output processing of step S1007 ends.

  In the next timer interrupt process in which the timer interrupt counter = 83 is set in step S1403, the process proceeds from step S1401 to S1402, and then it is determined in step S1402 that the timer interrupt counter is not "-1". The result is obtained. When it is determined that the timer interrupt counter is not "-1", the CPU 80a proceeds to step S1405 and determines whether the timer interrupt counter is "41". If the timer interrupt counter is not "41", the CPU 80a ends the insertion and payout signal output processing in step S1007. As a result, "0" (OFF) set in step S1404 is output as the input signal and the payout signal in the first half period of the timer interrupt counter 83 to 42.

On the other hand, if the timer interrupt counter is "41" in step S1405, the CPU 80a executes the processing in step S1406 and thereafter to output the input signal bit and the output signal bit according to the values of the input signal counter and the output signal counter. Perform processing to cause it.
Specifically, in step S1406, the CPU 80a determines whether or not the closing signal counter is other than “0”. If the closing signal counter is other than "0", the CPU 80a decrements (-1) the closing signal counter in step S1407, and in the subsequent step S1408, sets the closing signal, that is, "1" (ON) as the closing signal. After executing the setting process, the process proceeds to step S1409.
If the closing signal counter is not "0" in step S1406, the CPU 80a skips the processes of steps S1407 and S1408 and proceeds to step S1409. That is, if the closing signal counter is "0", the closing signal bit is not output.

In steps S1409 to S1411, the same processing as in steps S1406 to S1408 described above is performed on the payout signal. That is, in step S1409, the CPU 80a determines whether or not the payout signal counter is other than “0”, and if the payout signal counter is other than “0”, decrements (-1) the payout signal counter in step S1410, In a succeeding step S1411, a payout signal setting process, that is, a process of setting "1" (ON) as a payout signal is executed.
In response to the execution of the setting process of step S1411, the CPU 80a ends the insertion and payout signal output process of step S1007.
If the payout signal counter is not "0" in step S141409, the CPU 80a passes the processes of steps S1409 and S1410 and ends the input and payout signal output process of step S1007.

By executing the set processing of steps S1408 and S1411, the input signal and the payout signal are in the ON state from the timer interrupt processing where the timer interrupt counter = 41 to the timer interrupt processing where the timer interrupt counter = 0. Is continued. Then, in the timer interrupt processing subsequent to the timer interrupt processing in which the timer interrupt counter = 0, the timer interrupt counter = −1, the timer interrupt counter = 83 is set in step S1403, and the clear processing in step S1404 is executed. To be done. As a result, during the first half period of the timer interrupt counter 83 to 42, the input signal and the output signal continue to be in the OFF state.

[11-6. Regarding payout signal output during replay]

Here, as described above, for the payout signal, the payout signal bit for the automatic insertion number is output at the time of the replay, but conventionally, the payout signal output for the automatic insertion number of such a replay is output. If the game before the re-play is a winning game and the number of payouts due to winning is large, there is a possibility that it may not be possible to accurately notify the number of payouts.
Specifically, in the past, as the update of the payout signal counter according to the automatic insertion number of replays (step SS603: see FIG. 21), the update is performed by overwriting the automatic insertion number (that is, the payout signal in this example). Update to overwrite the counter with "3"). Therefore, when the number of prize-winning numbers in the pre-pre-replay game is large, the value of the payout signal counter is changed before the payout signal output corresponding to the prize-winning number is completed (that is, before the payout signal counter becomes “0”). There is a possibility that the number will be updated to "3", and there is a fear that the payout amount cannot be accurately notified to the hall computer.

This point will be specifically described with reference to FIG. 32.
As shown in the figure, it is assumed that the previous game has won the replay game, the current game is the replay game, and the number of prizes = the maximum number (“15” in this example) has been won in the two-preceding game.
As can be understood from the above description, the update of the payout signal counter according to the number of winning coins is triggered by the “winning medal payout process” of step S532 in the main process (FIGS. 19 to 20) described above. Further, when the payout signal counter becomes 1 or more, the output of the payout signal bit is started in the timer interrupt processing. Since the “winning medal payout process” in step S532 is started in response to the stop of the third rotating reel 4 in the one game (third stop), it depends on the number of winning coins in the two-preceding game. The output of the payout signal bit is started after the third stop of the game two times before.
In the figure, the output period of the payout signal bit corresponding to such a winning number is represented as a period Tho.

On the other hand, the update of the payout signal counter according to the replay is executed after the third stop of the previous game and before the lever ON of the current game (see FIG. 19).
Therefore, if the operation from the lever ON to the third stop of the previous game is quickly performed after the third stop of the two-preceding game that won the prize, the game is replayed before the payout signal output for the winning number is completed. There is a possibility that the payout signal counter is updated in accordance with the above, specifically, the payout signal counter is overwritten with “3” in the related art.
Here, when the winning number = the maximum number, the period Tho requires 125.16 ms (84 timer interrupt) × 15 = 1877.4 ms, which is shorter than the third from lever ON of the previous game in a shorter time. It is quite possible that the operation up to the stop will be performed.
In the slot machine, the shortest game interval (4.1s) is specified, but this does not specify the interval between the third stops.

  As described above, in the conventional method, the value of the payout signal counter may be overwritten to “3” before the output of the payout signal for the winning number of coins is completed. I couldn't do it.

Therefore, in the present embodiment, as the update of the payout signal counter according to the number of automatically inserted re-plays (step SS603), the process of adding the number of inserted medals of the previous game (“3”) to the payout signal counter as described above. Is supposed to run. In other words, the process of adding the number of automatically inserted replay games to the payout signal counter is performed.
By such addition update, it is possible to properly perform the payout signal output for the payout number according to the winning except the replay and the payout signal output for the automatic insertion number of the replay, The payout number can be accurately notified to the hall computer.

[11-7. Rotating cylinder control processing]

FIG. 33 is a flowchart of the barrel control process (S1013) in the timer interrupt process.
First, various flags representing the status of the rotary reels 4 used in the spinning control process of this example will be described. Specifically, it is the following six flags.

・ Flag FG1 in preparation for acceleration
・ Flag FG2 during acceleration
・ Flag FG3 during constant speed rotation
-Stop request flag FG4
・ Stopping flag FG5
・ Reel sensor non-passage flag Fmt

These six flags are provided for each rotary reel 4, and the CPU 80a can grasp the status of each rotary reel 4.

In FIG. 33, the CPU 80a first confirms the status of the target reel (the processing target rotary reel 4) in step S1501. That is, the statuses of the target reels are the acceleration preparation state (acceleration preparation flag FG1 = "1"), the acceleration state (acceleration flag FG2 = "1"), the constant speed rotation state (constant speed rotation flag FG3 = "1"), stop requesting state (stop requesting flag FG4 = "1"), stop operating state (stopping operating flag FG5 = "1"), all flags (FG1 to FG5) are OFF ("0") ) Check which state it is.
Here, the acceleration preparation flag FG1 is set in the reel start setting process (step S525) in the above-described main process after the lottery corresponding to the lever ON (specifically, after the wait time of 4.1 seconds has elapsed). When the rotation is started), the reel sensor non-passage flag Fmt is turned on. The acceleration preparation flag FG1 is turned on together with the reel sensor non-passage flag Fmt in response to the case where it is determined that the rotating reel 4 is accelerating or rotating in the above-described power restoration process (FIG. 16). (See S204).
Further, the accelerating flag FG2 is a flag that is updated to ON in step S1503 described below, and the constant-speed rotation flag FG3 is a flag that is updated to ON in step S1509 described below.
The stop request flag FG4 is a flag that is turned on in response to a valid stop button operation in the stop process (step S530) in the main process described above (see FIGS. 22 and 23).
The stop operation flag FG5 is a flag that is updated to ON in step S1526 described later.
The reel sensor non-passage flag Fmt is used to determine the start timing of counting the step position (and counting the symbol position) in the constant-speed rotation state.

  In step S1501, it is sequentially determined whether or not the flag = “1” in the order of the stop operation flag FG5, the stop request flag FG4, the constant speed rotation flag FG3, the acceleration flag FG2, and the acceleration preparation flag FG1. When it is determined to be "1" in the determination, the status corresponding to the flag determined to be "1" is set as the current status. Then, if the final acceleration preparation flag FG1 determined is “0”, the determination result that all flags are OFF is obtained.

As described above, the flags are checked in the reverse order of the processing sequence from the acceleration of the rotating cylinder to the stopping operation, and the status corresponding to the flag that is confirmed to be ON is determined as the current status. This has the following advantages.
As a method of determining the status, for example, a method of confirming whether or not only the target flag is “1” (for example, for determining whether or not the vehicle is in an accelerating state, only the accelerating flag FG2 is “1” However, in that case, a process of clearing the flag of the previous status is required according to the transition of the status. According to the status determination method described above, there is an advantage that the sequential clearing process of the previous status flag according to such a status transition can be omitted.

  In step S1501, if all flags are OFF, the CPU 80a advances the process to step S1533. As a result, the stepping motor 54 is maintained in the OFF state for the rotary reels 4 in the status of all flags OFF.

  In step S1501, if the status of the target reel is the acceleration preparation state (“1” in the figure), the CPU 80a proceeds to step S1502, and executes the initialization process at the start of activation. Specifically, the symbol counter is cleared and the step counter is set to the initial value "24". Further, the time table pointer (described later) is cleared and bit 0 of the excitation pointer PT is updated to "1". The excitation pointer PT is 4-bit information as described above. The significance of updating bit 0 of the excitation pointer PT to "1" will be described later.

  In response to the execution of the initialization process of step S1502, the CPU 80a updates the reel status to "accelerating" in step S1503, that is, after executing the process of turning on the acceleration flag FG2 ("1"), The process proceeds to step S1507.

  In step S1507, the CPU 80a sets the value of the phase update timer based on the startup time table. The start-up time table is a table that stores time information for realizing start-up rotation of the rotating reel 4.

FIG. 34 shows an example of the activation time table.
As shown in the figure, the startup time table is table information in which timer values to be set in the phase update timer are stored for each index value. The CPU 80a sequentially acquires the timer values in the ascending order of the index values (acquires every time the phase update timer value becomes "0": refer to S1505 and S1506), and sets the acquired timer value in the phase update timer.
Here, a pointer for pointing to the index being referred to among the indexes will be referred to as “timetable pointer Ptl” below. The initial value of the value of the timetable pointer Ptl is "0".

  In FIG. 33, the process of step S1507 acquires the corresponding timer value from the starting timetable according to the value of the index pointed to by the current timetable pointer Ptl for the target reel, and uses the acquired timer value as the phase update timer. It becomes the process of setting.

Here, after the acceleration flag FG1 is set in step S1503 and the timer value corresponding to the index = “0” is set in the start time table in step S1507, the phase update timer is set to step S1504. Is decremented by. That is, the phase update timer value is sequentially decremented for each timer interrupt.
As can be understood from this point, the timer value stored in the activation time table represents time information in timer interrupt units (in this example, 1.49 ms units).

In the startup time table, such time information in timer interrupt units stored for each index functions as information that defines the maintenance time of the two-phase excitation state and the one-phase excitation state of the stepping motor 54 at the time of startup. ..
Specifically, as described above with reference to FIG. 11, the stepping motor 54 of the present example is driven by 1-2 phase excitation, and the specific excitation mode is the excitation pointer (excitation phase pointer). ) Circularly indicated by the value of PT. As will be apparent from the description below, the value of the excitation pointer PT is the timer interrupt in which the accelerating flag FG1 is turned ON in step S1503 (that is, “1” corresponding to the index = “0” in the start time table in step S1507). In step S1524, a value for one-phase excitation (any one of 0, 2, 4, 6) is first set in step S1524. After that, in the timer interrupt during acceleration (acceleration flag FG1 is ON), the value of the excitation pointer PT is sent to the next value every time the value of the phase update timer becomes “0” in step S1505 (S1524). .. That is, every time the value of the phase update timer becomes “0” in step S1505, the excitation data φ1 to φ4 are alternately set as data for two-phase excitation → data for one-phase excitation → data for two-phase excitation. Will be done.

  As can be understood from this point, the timer value corresponding to the even-numbered index (including “0”) in the startup time table represents the maintenance time of the one-phase excitation state, and the timer value corresponding to the odd-numbered index is It represents the maintenance time of the two-phase excitation state.

  In FIG. 33, the CPU 80a determines in step S1508 whether or not the acceleration has ended in response to the execution of the timer value setting process in step S1507. Whether or not the acceleration has ended can be determined by whether or not the value of the time table pointer Ptl is a value indicating the final index (“19” in this example) in the activation time table. Alternatively, it can be determined by whether or not the value of the phase update timer matches the timer value (“134” in this example) corresponding to the final index in the activation timetable.

If the acceleration is not completed in step S1508, the CPU 80a proceeds to step S1524, increments (+1) the excitation pointer PT to acquire the excitation data φ1 to φ4, and sets the excitation data φ1 to φ4 in the output buffer in subsequent step S1532. To do.
It should be noted that the acceleration of the rotary reel 4 can be started from the one-phase excitation state by incrementing the excitation pointer PT by +1 in step S1524. Specifically, at the start of acceleration, since bit 0 of the excitation pointer PT is set to "1" in the previous step S1502, the value of the excitation pointer PT is set to "0, 2, 4" by incrementing the excitation pointer PT by +1 in step S1524. , 6 ”for the one-phase excitation, whereby the acceleration of the rotating reel 4 can be started from the one-phase excitation state.

  In response to executing the setting process of the excitation data φ1 to φ4 in step S1532, the CPU 80a determines in step S1533 whether all reels have ended. That is, it is determined whether or not the processing from step S1501 has been executed for all the spinning reels 4 (4a to 4c) in this timer interrupt. If all reels have not ended, the CPU 80a sets the target reel as the next rotating reel 4, and then returns to step S1501. If all reels have ended, the spinning cylinder control process ends.

  According to the flow of processing described above, the in-acceleration flag FG2 is turned on in response to the on-acceleration preparation flag FG1, and the timer value corresponding to the index = “0” of the startup time table is set in the phase update timer in step S1507. In the timer interrupt, the excitation data φ1 to φ4 corresponding to the one-phase excitation are set, and the target reel is started from the one-phase excitation state.

In the timer interrupt immediately after the acceleration flag FG2 is turned on, the status confirmation process of step S1501 confirms that the vehicle is in the acceleration state, and the process advances to step S1504. In step S1504, the CPU 80a decrements (-1) the value of the phase update timer, and in subsequent step S1505, determines whether the phase update timer value = "0".
Since the phase update timer value = “1” is set in the timer interrupt in which the accelerating flag FG2 is turned ON, the phase update timer value = “0” is determined in step S1505 in the timer interrupt immediately after that.
When the phase update timer value = “0” is determined in step S1505, the CPU 80a increments the value of the time table pointer Ptl in step S1506 and then advances the process to step S1507. As a result, the timer value corresponding to the value of the next index in the activation timetable is newly set in the phase update timer.

  In step S1508 following step S1507, it is determined whether or not the acceleration has ended, as described above. If not, the process proceeds to step S1524 as described above. As a result, in the timer interrupt immediately after the acceleration flag FG2 is turned on, the excitation state of the stepping motor 54 is changed from the one-phase excitation state to the two-phase excitation state.

Further, in subsequent timer interrupts during acceleration, the process transitions to steps S1501 → S1504 → S1505 → S1533 until the phase update timer value after decrement in step S1504 becomes “0”. That is, as a result, the excitation state of the stepping motor 54 is maintained in the excitation state corresponding to the excitation data φ1 to φ4 set in step S1532 for the time length corresponding to the timer value set in the phase update timer.
If it is determined in step S1505 that the phase update timer value = “0” in the timer interrupt after the excitation state is maintained for the time length corresponding to the set timer value, the process proceeds to step S1506. Then, the timer value corresponding to the value of the next index is set in the phase update timer, and thereafter, the stepping motor 54 responds to the set timer value by the new excitation state of the one-phase excitation state / two-phase excitation state. Driven for a length of time.
As described above, the one-phase excitation state / two-phase excitation state of the stepping motor 54 is alternately repeated a predetermined number of times according to the information stored in the start-up time table, whereby the target reel is accelerated and rotated.

At the end of the accelerated rotation of the target reel, the process proceeds in the order of steps S1501 → S1504 → S1505 → S1506 → S1507 → S1508, and it is determined in S1508 that the acceleration has ended.
If it is determined in step S1508 that the acceleration has ended, the CPU 80a sets the reel status of the target reel to "in constant speed rotation" in step S1509, that is, sets the constant speed rotation flag FG3 to ON, and advances the process to step S1510.

The processes after step S1510 (S1510 to S1516, S1524, and S1532 to S1533) are processes corresponding to the constant speed rotation.
First, in step S1510, the CPU 80a determines whether or not the reel sensor ON edge has been detected, that is, whether or not the ON edge of the index sensor 55 (for the target reel) has been detected.
If the ON edge of the index sensor 55 is detected and it is determined that the reel sensor ON edge is detected, the CPU 80a clears the reel sensor non-passage flag Fmt, clears the symbol counter, and advances to the step counter in step S1511. The initial value "24" is set. As a result, the reel sensor non-passage flag Fmt is turned off in response to the detection of the origin position 101 after the completion of the acceleration of the rotating reel 4, and the step counter and the symbol counter are set to values corresponding to the origin position 101. It is set (that is, the 24th symbol step position of the 1st symbol is indicated).
In step S1512 subsequent to step S1511, the CPU 80a decrements (-1) the value of the step counter. As a result, after passing the origin position 101, the value of the step counter is updated to 23 immediately after reaching 24 (that is, 24 steps of 23 to 0 can be cyclically counted).

  On the other hand, when it is determined that the ON edge of the index sensor 55 is not detected and the reel sensor ON edge is not detected, the CPU 80a passes step S1511 and proceeds to step S1512, and decrements the value of the step counter.

  In step S1513 following step S1512, the CPU 80a determines whether or not the value of the step counter = “0”. That is, it is determined whether or not the value of the step counter set to “24” → “23” according to the passage of the origin position 101 is subtracted in step S1512 for each timer interrupt and reaches “0”. ..

  If the value of the step counter is not "0" in step S1513 (that is, it is not the symbol break position), the CPU 80a executes the processing of step S1524 and subsequent steps described above. As a result, the stepping motor 54 is driven in a mode in which the one-phase excitation state and the two-phase excitation state are alternately repeated even during constant speed rotation. However, during constant speed rotation, the switching cycle of the one-phase excitation state and the two-phase excitation state is the timer interrupt cycle (switching for each timer interrupt).

On the other hand, if the value of the step counter = “0” in step S1513, the CPU 80a proceeds to step S1514, sets “24” in the step counter, and increments (+1) the value of the symbol counter, In step S1515, it is determined whether or not the value of the symbol counter is larger than "22". This corresponds to determining whether or not the symbol counter shows an abnormal value (the number of symbols on the rotating reel 4 is "21").
If the value of the symbol counter is larger than "22", the CPU 80a performs a process for restarting the rotating reel 4 in step S1516. Specifically, the reel sensor non-passage flag Fmt and the acceleration preparation flag FG1 for the target reel are set, and the constant speed rotation flag FG3 and the acceleration flag FG2 are cleared. As a result, in the next timer interrupt, the process is executed via steps S1501 → S1502, and the target reel is restarted (the acceleration process is executed again).
In response to executing the process of step S1516, the CPU 80a advances the process to step S1524.

  If the value of the symbol counter is not larger than "22" in step S1515, the CPU 80a skips the process of step S1516 corresponding to the abnormal condition and executes the processes of step S1524 and subsequent steps.

Here, in this example, regarding the step counter and the symbol counter, initial values are set at the start of acceleration of the target reel (step S1502 described above) (“24” and “0”, respectively). Further, after the end of acceleration, the process proceeds to steps S1510 → 1512 until the origin position 101 is detected, and the decrement of the step counter or the symbol corresponding to the step counter = “0” is set. The counter is incremented (S1514). That is, in this example, the number of symbol steps and the number of symbols (the number of frames) are counted even after the acceleration of the target reel is completed and before passing through the origin position 101.
Thereby, even between the end of the acceleration rotation and the detection of the origin position 101, the revolving cylinder can be restarted according to the error of the symbol counter (symbol counter> 22). Therefore, the accuracy of the rotating cylinder control can be improved.

  Next, the processing executed after the stop request flag FG4 is set on the main processing side will be described. In other words, a valid stop button operation is detected (see step S703 in FIG. 22), and the number of sliding symbols (scheduled stop position: stop symbol position) for the target reel is determined (steps S801 to S806 in FIG. 23). Refer to the process).

  In the timer interrupt immediately after the stop request flag FG4 is set on the main processing side, it is determined in step S1501 that the status of the target reel is the stop requesting status, and the processing in step S1517 and thereafter is executed.

  First, in step S1517, the CPU 80a acquires the value of the sliding piece counter, and in subsequent step S1518, determines whether or not the value of the sliding piece counter = “0”. The sliding frame counter is a counter for grasping the number of sliding frames from the time when the number of sliding frames is determined, and when the stop request flag FG4 is turned on, the number of sliding frames determined by the main processing side (see S802). ) Is set, and thereafter, each time the symbol counter is incremented, it is decremented in step S1523 described later on the timer interrupt side.

If the value of the sliding piece counter is not "0" in step S1518, the CPU 80a executes the processes of steps S1520 to S1522 to decrement the step counter (S1520), and the step counter and the symbol counter according to the value of the step counter. Is updated (S1521, S1522).
Here, in the update process of step S1522, when the value of the symbol counter becomes “21” (that is, when it becomes a value representing the 22nd symbol), it is cleared (returned to “0”). In the processing after step S1517 corresponding to the reel status = requesting stop, processing for determining whether or not the reel sensor ON edge is detected, such as during constant speed rotation, is not provided. During the stop request, the symbol counter is not cleared according to the reel sensor ON edge like during constant speed rotation, but is cleared when the value of the symbol counter becomes "21".

In response to updating the values of the step counter and the symbol counter in step S1522, the CPU 80a decrements the value of the sliding piece counter in step S1523.
The CPU 80a advances the process to step S1524 in both the case where the decrement process of step S1523 is executed and the case where it is determined in the previous step S1521 that the value of the step counter is not “0”. As a result, the 1-2 phase excitation of the target reel is continued even in the state where the stop request is being made (the state where the frame is sliding), and the constant speed rotation is maintained.

Further, in the previous step S1518, if the value of the sliding piece counter = “0”, that is, if reaching the stop symbol position (scheduled stop position) is detected, the CPU 80a determines in step S1519 whether it is the stop permission step position. Determine whether or not. That is, it is determined whether or not the value of the step counter matches the value representing the stop permission step position (step position 7 in this example) described in FIG.
If it is not the stop permission step position, the CPU 80a advances the process to step S1520. That is, in this case, the step counter is updated until the stop permission step position is reached.

On the other hand, if it is the stop permission step position, the CPU 80a executes the processing of step S1525 and thereafter to stop the rotation of the target reel.
First, in step S1525, the CPU 80a executes a process of setting data corresponding to all phases ON as the excitation data φ1 to φ4, and updates the reel status to “during stop operation” in subsequent step S1526. That is, the stop operation flag FG5 is turned on. Then, the CPU 80a advances the process to step S1532 described above. As a result, the excitation data φ1 to φ4 corresponding to all phases ON are set in the output buffer, and the stop drive of the stepping motor 54 of the target reel is started.

In the timer interrupt after the reel status is updated to "stopping" in step S1519, the process for the target reel proceeds from step S1501 to S1527.
In step S1527, the CPU 80a decrements the phase update timer value, and in step S1528 determines whether the phase update timer value = "0". If the phase update timer value is not "0", the CPU 80a proceeds to step S1533. That is, the all-phase ON state is maintained until the phase update timer value = “0”.
Since the phase update timer for the target reel is set to "134" at the end of acceleration (see FIG. 34), the brake control for turning on all phases is continued for 1.49 ms × 134 = 199.66 ms. It

  If the phase update timer value = “0”, the CPU 80a proceeds to step S1529 and adds a predetermined value to the value of the excitation pointer PT. Specifically, in this example, "4" is added. The significance of adding a predetermined value to the value of the excitation pointer PT after the end of the brake control by all-phase excitation will be described again.

  Then, the CPU 80a sets the data corresponding to all phases OFF as the excitation data φ1 to φ4 in step S1530, and in step S1531, the reel status clearing process, specifically, the acceleration preparation flag FG1, the acceleration flag FG2, Processing for clearing the constant speed rotation flag FG3, the stop request flag FG4, and the stop operation flag FG5 is executed, and the excitation data setting processing in step S1532 is executed. As a result, the excitation state of the stepping motor 54 is shifted to the all-phase OFF state in accordance with the end of the brake control by the all-phase excitation, and various flags related to the rotation / stop of the rotary reel 4 are switched to OFF. By turning OFF these various flags, the excitation state of the stepping motor 54 is maintained in the OFF state of all phases thereafter (see the path of S1501 → S1533).

Here, the rotation reel 4 does not stop at the step position where the brake is applied even if the brake control for the stepping motor 54 is started, but stops at the step position advanced to some extent. Specifically, in the slot machine of the present example, the rotating reel 4 is stopped at the step position that is advanced by 4 steps from the step position where the brake is applied (step position where all phases are ON) (at the time of stop from steady rotation).
Therefore, in this example, the value of the excitation pointer PT is "+4" after the rotation reel 4 is stopped in response to the brake control. Specifically, according to the processing of step S1527 described above, the value of the excitation pointer PT is incremented by “+4” at the timing when the all-phase ON hold for a predetermined time is completed.

  As a result, the position of the excitation pointer PT can be advanced according to the difference between the step position where the brake is applied and the step position where the rotary reel 4 is actually stopped, and accurate reel control can be realized.

  In the above description, the example in which the timing of updating the position of the excitation pointer PT to the position advanced by the predetermined number is set to the end time point of the all-phase ON hold is described. However, the timing is after the next start rotation of the target reel is updated. It may be set so as to start with the position of the excitation pointer PT as a reference, and may be set to another timing such as the timing of step S1502.

By the spinning cylinder control process (S1013) as described above, the CPU 80a controls the acceleration → constant speed rotation, and counts the symbol step position and the symbol position for each rotating reel 4. Then, after shifting to the constant speed rotation, in response to the effective stop button operation being performed after the origin position 101 is passed (reel sensor non-passage flag = OFF) (stop request flag FG4 = ON), the target The number of sliding pieces of the reel is monitored (S1518) and stopped (S1525 and thereafter).
At this time, in step S1533, it is determined whether or not all reels have ended, and if all reels have not ended, the processing from step S1501 is executed for the next rotating reel 4. As can be understood from this point, in the spinning drum control process, it is possible to simultaneously monitor the number of sliding symbols for each of the rotating reels 4a to 4c in parallel. In other words, with respect to the rotating reels 4a to 4c, it is possible to simultaneously monitor the frame slip from the stop operation symbol to the stop symbol in parallel.

This eliminates the need for the main processing side to monitor the number of sliding pieces of the rotary reel 4 on which the stop button operation has been performed. That is, the main processing side waits for the arrival of the stop symbol position of the rotating reel 4 operated by the stop button until the acceptance of the next stop button operation is enabled after the operation of the stop button of the certain rotating reel 4. There is no need to do this (see FIGS. 22 and 23). Therefore, the main processing side can immediately enable acceptance of the next stop button operation after the stop symbol position is determined.
Therefore, it is not necessary for the player to be aware that the stop operation intervals of the respective rotary reels 4 should be provided, and thus the hitting comfort of the gaming machine can be improved.

Further, as will be understood from the above description, in the slot machine of this example, the arrival of the stop symbol position is the timer interrupt processing side for the target reel which is the rotating reel 4 whose stop symbol position (number of sliding symbols) is determined. It is supposed to be monitored in (S1518).
This eliminates the need for the main processing side to monitor the arrival of the stop symbol position for the target reel, while the main processing side operates the stop button of the target reel until the acceptance of the next stop button operation is validated. In addition, it is not necessary to wait for the arrival of the stop symbol position for the target reel. Therefore, the main processing side can immediately enable acceptance of the next stop button operation after the stop symbol position is determined.
Therefore, it is not necessary for the player to be aware that the stop operation intervals of the respective rotary reels 4 should be provided, and thus the hitting comfort of the gaming machine can be improved.
