FIG. 5 is a flowchart showing a main process executed by the CPU in the game control section 11. When the power to the gaming machine is turned on, in the main processing, C
The PU performs necessary initialization processing.

In the initial setting process, the CPU first
The interrupt is set to be prohibited (step S101: hereinafter simply referred to as S101). Next, the interrupt mode is set to the interrupt mode 2 (S102), and the stack pointer designated address is set to the stack pointer (S103). Then, the internal device registers are initialized (S10).
4). In addition, a built-in device (built-in peripheral circuit) CT
After initialization of C (counter / timer) and PIO (parallel input / output port) (S105), the RAM is set to an accessible state (S106).

The CPU used in this embodiment has the following three types of maskable interrupt (INT) modes. When an interrupt that can be masked occurs, the CPU automatically sets the interrupt disabled state and saves the contents of the program counter on the stack.

Interrupt mode 0: The internal device that has issued the interrupt request sends an RST instruction (1 byte) or a CALL instruction (3 bytes) onto the internal data bus of the CPU.
Therefore, the CPU executes the instruction at the address corresponding to the RST instruction or the address specified by the CALL instruction. Upon reset, the CPU automatically enters interrupt mode 0. Therefore, when it is desired to set the interrupt mode 1 or the interrupt mode 2, it is necessary to perform a process for setting the interrupt mode 1 or the interrupt mode 2 in the initial setting process.

Interrupt mode 1: In this mode, when an interrupt is accepted, it always jumps to address 0038 (h).

Interrupt mode 2: An address synthesized from the value (1 byte) of the specific register (I register) of the CPU and the interrupt vector (1 byte: least significant bit 0) output from the built-in device indicates an interrupt address. Mode. That is, the interrupt address is an address indicated by 2 bytes in which the upper address is the value of the specific register and the lower address is the interrupt vector. Therefore, it is possible to provide an interrupt process at an arbitrary even-numbered address although it is discrete. Each built-in device has a function of transmitting an interrupt vector when making an interrupt request.

Therefore, when the interrupt mode 2 is set,
An interrupt request from each built-in device can be easily processed, and an interrupt process can be provided at an arbitrary position in a program. Further, unlike the interrupt mode 1, it is easy to prepare respective interrupt processing for each interrupt occurrence factor. As described above, in this embodiment, the CPU is set to the interrupt mode 2 in S102 of the initial setting process.

Next, it is determined whether or not a clear switch provided on the gaming machine is in an on state (S107).
When the clear switch is on (S107;
Y), while shifting to S110 described later, if the clear switch is not in the ON state (S107; N), it is determined whether or not data protection processing (for example, addition of parity data, etc.) of the backup RAM area was performed when the power was turned off. Confirmation (S108). In this embodiment, when an unexpected power failure occurs, a process for protecting data in the backup RAM area is performed. The case where such protection processing has been performed is regarded as backup. That is,
After confirming that there is no backup, the CPU executes an initialization process after S110.

After confirming that there is a backup, the CPU
Performs a game state restoration process for returning the internal state of the game control unit 11 and the control state of the electric component control means such as the display control unit 13 to a power-off state (S109). Then, the saved value of the PC (program counter) stored in the backup RAM area is reset to the PC, and returns to the address.

As shown in the flowchart of FIG. 6, the power-off processing is performed after the register is saved (S201) and the stack pointer is saved (S202).
An M checksum operation is performed (S203). Next, RAM
Is set to access prohibition (S204), the output port is cleared (S205), and the process stands by (loop).

In the initialization processing, first, the CPU
A clear process is performed (S110). Further, an initial value setting process for setting an initial value in a predetermined work area (for example, a random number counter for normal symbol determination, a buffer for normal symbol determination, a special symbol left middle right symbol buffer, a payout command storage pointer, and the like) is also performed. Further, a process for initializing the sub-boards (symbol control board, voice control board, lamp control board, payout control board, etc.) is executed (S111). As a process of initializing the sub-board, for example, a process of transmitting an initial setting command is performed, and as the initial setting command, a payable state designation command or a non-dischargeable state output to the payout control unit 16 in the case of the payable state. In this case, a payout stop state designation command or the like is transmitted. As a dispensable state, for example, there is a state in which a ball out switch or a full tank switch (both not shown) are on. That is, the CPU:
If the ball out switch or the full tank switch is turned on, a payout stop state designation command is sent to the payout control unit 16,
Otherwise, it sends out a payable state designation command. Note that the payout possible state designation command or the payout stop state designation command may be configured to be executed also in the game state restoration processing in S109.

Then, the register of the CTC provided in the CPU is set so that a timer interrupt is periodically generated every 2 ms (S112). That is, a value corresponding to 2 ms is set in a predetermined register (time constant register) as an initial value.

Thereafter, an interrupt disabled state is set (S11).
3) After that, the display symbol random number updating process of updating the count value of the counter for generating the display random number (S11)
4) and an initial value determination random number update process (S115), and thereafter, a process of setting an interrupt permission state (S11)
6) is repeatedly executed.

It should be noted that interrupt prohibition is realized by issuing an interrupt prohibition instruction, setting an interrupt prohibition register to prohibition, or setting a mask register. This is realized by setting a register for interrupt prohibition to enable or resetting a mask register. Further, the initial value determination random number is a random number for determining an initial value of the big hit determination random number.

The counter updating process (numerical value updating process) of the counter in the display symbol random number updating process (S114) and the initial value determining random number updating process (S115) is executed in an interrupt disabled state. Therefore, a maskable interrupt such as a timer interrupt does not occur when the numerical value updating process is being executed. That is, the numerical value update processing is executed without being interrupted by the interrupt processing.

In this embodiment, the built-in CTC of the CPU is set to repeatedly generate a timer interrupt. In this embodiment, the repetition period is set to 2 ms.
When a timer interrupt occurs, a timer interrupt process as illustrated in FIG. 7 is executed. In the timer interrupt process, the CPU executes the save process of the register, and then executes S
Each game control process from 302 to S314 is executed. When the game control process is completed, a register return process is performed (S3
15), the interrupt is permitted (S316).

In the game control process, the CPU first
Through a switch circuit (not shown), a gate switch,
The state of switches such as a start-up opening switch, a count switch, and a winning opening switch (both not shown) are input, and their states are determined (switch processing: S302).

Next, various abnormality diagnosis processes are performed by the self-diagnosis function provided inside the pachinko gaming machine 1, and an alarm is issued if necessary according to the result (error process: S303).

Next, a random number updating process for updating each counter indicating a random number for determination, such as a random number for big hit determination used in game control, is performed (S304). The CPU further performs an initial value determination random number update process (S305) and a display symbol random number update process (S306). Note that S305 and S305
The content of the process of 306 is the same as the process of S115 and S114.

Further, the CPU performs a special symbol processing process, which will be described in detail later (S307). In the special symbol process process, a corresponding process is selected and executed according to a special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to a gaming state. Then, the value of the special symbol process flag is updated during each processing according to the gaming state. Further, the CPU performs a normal symbol process process, which will be described in detail later (S308). In the normal symbol process process, a corresponding process is selected and executed according to a normal symbol process flag for controlling lighting of the variable display 18 by a pair of left and right LEDs in a predetermined manner. Then, the value of the normal symbol process flag is updated during each processing according to the gaming state.

Next, the CPU performs a process of setting a display control command relating to the special symbol in a predetermined area of the RAM and transmitting the display control command (special symbol command control process: S309). Further, a process of setting a display control command relating to a normal symbol in a predetermined area of the RAM and transmitting the display control command is performed (normal symbol command control process:
S310).

Further, the CPU performs an information output process of outputting data such as jackpot information, start information, and probability variation information supplied to the hall management computer (S).
311).

The CPU issues a drive command to a solenoid circuit (not shown) when a predetermined condition is satisfied (S3).
12). The solenoid circuit drives a solenoid (not shown) in response to the drive command to open or close the special symbol starting port 6 or the special winning opening 7.

Then, the CPU executes prize ball processing for setting the number of prize balls based on the detection output of a switch for detecting a prize in each winning port (S313). Specifically, a payout control command is output to the payout control unit 16 in response to the winning detection. A payout control CPU (not shown) mounted on the payout control unit 16 drives a ball payout device (not shown) according to a payout control command.

With the above control, in this embodiment,
The game control process is started every 2 ms. Also, until all of the game control processing is executed, the interrupt is not enabled, so that no other interrupt or the next timer interrupt occurs, and all the processing during the game control processing is reliably executed. Complete.

FIG. 8 is a flowchart showing an example of a special symbol process processing program executed by the CPU. The special symbol process process shown in FIG. 8 is a specific process of S307 in the flowchart of FIG. CP
U performs a variation reduction timer subtraction process when performing the special symbol process process (S401), and then determines whether or not the switch (first-type startup port switch) of the special symbol startup port 6 is on. It is determined (S402). If the first-type starting port switch is on (S402; Y), and if the number of stored starting winnings is not full, the first-type starting port for increasing the number of stored starting winnings and extracting a random number for jackpot determination and the like. The switch passage processing (S403) is performed. On the other hand, if the first-type starting port switch is not in the ON state (S402; N), S4
In step S404, any one of steps S404 to S412 is performed according to the internal state (special figure flag information) without performing the processing of step S03. The fluctuation shortening timer is a timer for setting the fluctuation time when the fluctuation time of the special symbol is shortened. The value of the special figure flag information is updated during each process according to the gaming state.

When the value of the special figure flag information is “00H”,
A “special symbol normal process” in a normal game state such as a process of determining whether or not the random number value drawn in the special figure game matches the big hit value or notifying the outside to the outside is executed (S404). When the value of the special symbol flag information is “01H”, “special symbol stop symbol setting processing” for setting a stop symbol in the special symbol game performed on the special symbol display device 4 is executed (S405). The value of the special figure flag information is “02”
In the case of H ", a" variable display pattern setting process "for setting a variable display pattern of a symbol of the special figure game performed on the special symbol display device 4 is executed (S406).

When the value of the special figure flag information is “03H”,

When the value of the special figure flag information is “05H”, a “large winning opening pre-opening process” for performing an initialization process for the big hit operation is executed (S409).

When the value of the special figure flag information is “06H”,
Various processes relating to the jackpot operation and a "winning opening process" for checking the opening time of the jackpot 7 per one time are executed (S410). When the value of the special figure flag information is “07H”, a “specific area effective time process” is executed to monitor the passage of the game ball to the specific area switch and determine whether or not the special symbol process has ended (S41).
1). When the value of the special figure flag information is "08H", it is determined whether or not the special symbol process has been completed. If the special symbol process has been completed, the demonstration display (big hit screen) flag is cleared, the big hit display pattern is cleared, and the big hit end display is made. "Big hit end processing" for clearing and clearing big hit information is executed (S4).
12).

It should be noted that the processes executed in the special symbol process are not limited to the above-described processes, but may be replaced with other processes or other processes may be added. Also, if the processing contents of each processing branched according to the value of the special figure flag information become complicated and the processing cannot be completed within the timer interrupt time,
A plurality of the same processes may be added.

In the special figure game, when the game ball passes through the special symbol starting port 6, a special symbol big hit or a loss is determined based on the value of the random number for determination. As a result of the determination, when a big hit occurs, the special symbol combination corresponding to the value of the random number for determination is displayed on the special symbol display device 4. On the other hand, when a loss occurs, a special symbol corresponding to the value of the display symbol random number is displayed.

FIG. 9 is a flowchart showing an example of a program for the ordinary symbol process executed by the CPU. The normal symbol process process shown in FIG. 9 is a specific process of S308 in the flowchart of FIG. CP
U determines the ON state of the gate switch (not shown) based on the passing of the ball through the passage gate 19, which is a condition for starting the normal symbol change, when performing the normal symbol process process (S50).
1). When the gate switch is on (S50
1; Y), if the number of stored gate passages is not full, the number of stored gate passages is incremented by one, and a gate switch passage process (S502) for extracting a hit determination random number and the like is performed. On the other hand, when the gate switch is not on (S501;
N), without performing the processing of S502, any one of S503 to S506 is performed according to the internal state (general-purpose flag information). The value of the general flag information is updated during each process according to the gaming state.

When the value of the general-purpose flag information is “00H”,
A “normal symbol normal process” in a normal game state, such as a process of determining whether or not a random number value selected in a common game matches a hit value or notifying the outside, is executed (S503). When the value of the ordinary figure flag information is “01H”, the “ordinary symbol variation processing” for performing the variation processing in the ordinary figure game is executed on the variable display 18 (S50).
4). When the value of the ordinary symbol flag information is “02H”, “ordinary symbol stop processing” for performing an ordinary symbol stop processing is executed (S505). When the value of the ordinary figure flag information is “03H”, the electric tulip type accessory 5
"Ordinary electric accessory actuation process"
Is executed (S506).

The processes executed in the normal symbol process are not limited to the above-described processes, but may be replaced with other processes or further other processes may be added.

In the general-purpose game, a game ball is passed through the passing gate 19.
Is passed, the normal pattern is hit based on the value of the random number for determination, and the loss is determined. If the result of the determination is that a hit has occurred, a normal symbol for the hit is displayed on the variable display 18 (the hit LED of the pair of left and right LEDs is turned on). On the other hand, in the case of a loss, the normal pattern of the loss is displayed on the variable display 18 (the lost LED of the pair of left and right LEDs is turned on).

Hereinafter, the game controller 11 to the display controller 13
The image display processing performed by the display control unit 13 based on the display control command data output to the CPU will be described in detail. Note that in the image display processing by the display control unit 13, it is not always necessary to execute the processing procedure according to the flowchart described below as long as the same image display is apparently performed.

FIG. 10 is a flowchart showing a display control process. The display control unit 13 determines whether or not a variable display pattern command has been input from the game control unit 11 (S601). When the fluctuation display pattern command is input (S601; Y), a random number extraction process for extracting a random number for determining the type of the announcement effect accompanying the fluctuation display is performed (S602). Next, it is determined whether or not there is an apparent reach effect (S603). When performing a reach effect (S60
3; Y), it is determined whether or not the reach effect type is super reach (S604). If it is not super reach (S604; N), the process returns to the main flow after performing a normal reach effect display process (S605) for displaying an image for a normal reach effect on the special symbol display device 4.
On the other hand, if it is super reach (S604; Y), the process returns to the main flow after performing a super reach effect display process (S606) for displaying an image for super reach effect on the special symbol display device 4.

If it is determined in S603 that a reach effect is not to be performed (S603; N), it is determined whether or not a predetermined number (four) of symbol storages are stored (S607). If there is a pending storage (S607; Y), the process returns to the main flow as it is, while if there is no pending storage (S607;
N), it is determined whether or not a predetermined period of time has elapsed since the symbol fluctuation stopped (S608). If the fixed time has not elapsed (S608; N), the process returns to the main flow, and if the fixed time has elapsed (S60).
8; Y), after performing the demonstration display process (S609) for displaying the demonstration display image on the special symbol display device 4, return to the main flow.

If no variable display pattern command is input in S601 (S601; N), it is determined whether or not a big hit is in progress (S610). If it is not during the big hit (S610; N), the process proceeds to S607. If the big hit is made (S610; Y), information relating to the big hit (number of rounds, big hit design, etc.) is displayed on the special symbol display device 4 as an image. After performing the big hit display process (S611), the process returns to the main flow.

Next, a specific display image of symbol fluctuation will be described. As shown in FIG. 11, the special symbol display device 4 has variable display portions 50a to 50i for individually and variably displaying nine symbols of three vertical symbols and three horizontal symbols. It is assumed that a total of eight horizontal, left vertical, middle vertical, right vertical, lower left diagonal, lower right diagonal lines are set as the effective lines of the jackpot combination. First, the display image at the time of the normal fluctuation will be described with reference to FIGS. In the normal gaming state at which the symbol change starts, the display result (stop symbol) at the time of the previous symbol change is displayed in each of the variable display portions 50a.
５０50i is stopped and displayed. However, among these, the variable display units 50a to 50c that are upper horizontal lines and the variable display units 50g to 50i that are lower horizontal lines are each integrally formed with stop symbols on each line as shown in FIG. The mask symbols 51 and 52 to be covered are displayed, and the stop symbols are visible only in the variable display portions 50d to 50f that are the middle horizontal lines.

When the symbol change starts in accordance with the winning of the special symbol starting port 6, as shown in FIGS. 11B and 11C, the upper and lower mask symbols 51 and 52 respectively move in the vertical direction. By being moved and displayed, the stop symbols of the variable display units 50a to 50c serving as upper horizontal lines and the variable display units 50g to 50i serving as lower horizontal lines become visible, and at the same time, all the variable display units 50a Symbol fluctuation starts at 50i. Thereafter, as shown in FIGS. 11 (D) and 11 (E), the two symbols of the variation display sections 50a and 50i at the upper left and the lower right are stopped and displayed first, and then the middle upper, the middle left and the middle right are displayed. , Middle and lower variation display sections 50b, 50d, 50f, 5
0h (see FIGS. 11 (E) and 11 (F)), and then two symbols (see FIGS. 11 (F) and 11 (G)) on the variable display portions 50c and 50g which are upper right and lower left. Stop display is performed, and finally, as shown in FIG. 11 (H), the symbol of the central fluctuation display section 50e is stopped and displayed, and the display result is derived. FIG. 11 illustrates a case where the display result is lost without the reach effect.

Further, although not shown, the variable display section 50g-
After all the symbols 50i stop changing and the display result is derived, the upper and lower mask symbols 51 and 52 respectively appear from the upper and lower directions and become the upper and lower horizontal variation display units 50a to 50a.
c and the stop symbols of the variable display portions 50g to 50i that are the lower horizontal lines are hidden by the mask symbols 51 and 52 (the variable display portion 50d that is the middle horizontal line as shown in FIG. 11A).停止 50f only stop symbols are visible). In other words, in the present embodiment, the effective display of one line is set using the fluctuation display units 50d to 50f serving as the middle horizontal lines as basic fluctuation display units, and pseudo display is performed by increasing the fluctuation display units that can be visually recognized at the start of the fluctuation. After the effective lines are changed to eight lines, the effective lines are returned to one line again after the display result is derived.

Next, the difference between the display image of the normal reach effect and the display image of the super reach effect will be described with reference to FIG.
This will be described with reference to FIGS. First, in the normal reach effect, as described in FIG.
When the symbol change is allowed along with the winning of the prize, FIG.
From the start state of the symbol change shown in (A), FIG.
As shown in (D), the upper and lower mask symbols 51 and 52 are moved and displayed in the vertical direction, respectively, so that the variable display units 50a to 50c to be upper horizontal lines and the variable display units 50g to 50i to be lower horizontal lines. Are stopped, and at the same time, the symbol variation is started in all the variation display sections 50a to 50i. After that, a reach effect is performed on any of the eight effective lines.

On the other hand, in super reach production,
When the symbol change is started in accordance with the winning in the special symbol start-up opening 6, the upper and lower masks are changed from the start state of the symbol change shown in FIG. 12 (E) as shown in FIGS. 12 (F) to 12 (H). Pattern 5
By moving and displaying 1 and 52 rightward and leftward, respectively, the stop symbols of the variable display portions 50a to 50c serving as upper horizontal lines and the variable display portions 50g to 50i serving as lower horizontal lines become visible. Simultaneously, the symbol variation is started in all the variation display sections 50a to 50i. That is,
In super reach direction, upper and lower mask designs 51, 52
Are moved rightward and leftward, respectively, and this is a notice of super reach. After that, a reach effect is performed on any of the eight effective lines. When the super reach effect is performed, the reliability of the big hit is set higher than when the normal reach effect is performed.

In the above-described embodiment, the mask symbols 51 and 52 for hiding the stop symbols of the variable display portions 50a to 50c serving as upper horizontal lines and the variable display portions 50g to 50i serving as lower horizontal lines are arranged in the vertical direction. Alternatively, by moving and displaying in the left-right direction, the variable display units 50a to 50c and 50g are displayed.
Although the concealment of 50i to 50i is released, other than this, as shown in FIG.
2 is moved to the left direction, the mask patterns 51 and 52 are moved to the right direction as shown in FIG. 13B, and the mask patterns 51 and 52 are moved to the right direction as shown in FIG. The display of FIG.
As shown in FIG. 13 (D), the mask designs 51, 52 are gradually reduced in size, or as shown in FIG. 13 (E), the mask designs 51, 52 are rotated around the center line in the left-right direction as the rotation axis. Alternatively, as shown in FIG. 13 (F), the mask designs 51 and 52 are rotated and displayed with the center line orthogonal to the screen as the rotation axis, so that the variation display units 50a to 50c,
The concealment of 50g to 50i may be released. Further, as shown in FIGS. 13G and 13H, a mask pattern 53 is individually provided for each of the variable display sections 50a to 50c and 50g to 50i, and each mask pattern 53 is rotated about a vertical center line. The concealment of the variable display units 50a to 50c and 50g to 50i may be canceled by rotating and displaying the axis.

As a configuration for hiding the variable display section,
Although the one that displays the concealed image (mask pattern) is illustrated,
However, the present invention is not limited thereto, and the variable display unit may be concealed by other variable display units so that the variable display unit is concealed. For example, as shown in FIG. 14 (A), when the symbol is stopped, the variable display portions 50d to 50f, which are the middle horizontal lines, are displayed, and the upper and lower display areas are replaced with character display portions instead of the variable display portions. 54a and 54b are displayed. When the symbol change is permitted in accordance with the winning in the special symbol start-up opening 6, as shown in FIGS. 14 (B) to (D), the upper and lower characters 54a and 54b each have a middle horizontal line. By vertically pulling out the variable display units 50a to 50c serving as upper horizontal lines and the variable display units 50g to 50i serving as lower horizontal lines hidden by the units 50d to 50f, finally, three vertical symbols are displayed. The variable display units 50a to 50i for individually and variably displaying nine horizontal symbols are displayed, and symbols are changed in all the variable display units 50a to 50i.

Further, as shown in FIG. 14 (E), when the symbol is stopped, the variation display sections 50d to 50d to become middle horizontal lines.
0f may be displayed on the entire screen (displayed in a vertically elongated shape as compared with normal time). Then, when the symbol change is permitted along with the winning in the special symbol starting port 6, FIG.
As shown in (F) to (H), the vertically long variable display unit 5
0d to 50f are gradually reduced, and the fluctuation display sections 50d to 50d
Variation display units 50a to 50h that are upper horizontal lines hidden by 50f
0c and variable display portions 50g to 50i serving as lower horizontal lines
By making the display relatively large, in the end,
The variable display units 50a to 50i for individually and variably displaying a total of nine symbols of three vertical symbols and three horizontal symbols are displayed, and symbols are changed in all the variable display units 50a to 50i.

As described above, according to the configuration of this embodiment, it is possible to conceal and release some of the plurality of variable display units 50g to 50i (variable display units 50a to 50c, 50g to 50i). In other words, a plurality (eight in the embodiment) of hit lines can be set in a pseudo manner. For this reason, the main game control unit 11 can control only the variable display units 50d to 50f that constitute a hit line of one line, and the other display lines can be controlled by the display control unit 13 on the sub side. The processing load on the game control unit 11 relating to the display control of the special symbol display device 4 can be reduced.

In this configuration, the variable display section 50
Mask pattern 5 for concealing a to 50c and 50g to 50i
The variable display units 50a to 50c and 50g are arranged so that the variable display units 50a to 50c and 50g to 50i can be easily viewed by moving, reducing, deforming, or deleting them.
It is possible to improve the visual appeal for hiding the hiding of g to 50i.

Further, in normal times when the symbols are not being displayed in the variable display mode, the mask symbols 51 and 52 are used to display the variable display portions 50a to 50a.
Since 50c and 50g to 50i are concealed, it is not necessary to set a plurality of hit lines in a pseudo manner when the symbol stops changing.

In the above-described embodiment, the function of the image display device for displaying the character image and the background image related thereto is combined with the variable display device (special symbol display device 4) for variably displaying the identification information.
