On the other hand, in step S120, the count values of various random number generation loop counters (not shown) for large hit determination, small hit determination, and the like formed in the RAM 203 are incremented. Update the timer value of the timer. Therefore, at the time of initial power-on, initialization such as RAM clearing and initial data setting processing is performed, and a predetermined stack value is stacked in the stack area of the main control unit 200. And the like, and a second predetermined stack value corresponding to the initialization is stacked in the stack area of the main control unit 200.

Next, in step S140, a special symbol start switch 304, a normal symbol operation switch 306,
An input port process of reading and storing the detection signal output from the special winning opening switch 308 into a register (not shown) via the input port 210 is executed, and then the process proceeds to step S150 to read and store the data read by the port input process. Switch check processing for grasping the condition.

Next, in step S160, each switch 3
A check is made to see if there is a disconnection or short-circuit in the lines 04, 306, 308, etc., and if any of these failures has occurred (Ye
s) The process proceeds to step S220, but otherwise (No), the process proceeds to step S180 (step S180).

In step S180, data necessary for display control of the ordinary symbol display device 108 is stored in the RAM.
203 and a command necessary for display control of the special symbol display device 100 (see FIGS. 6 to 9).
(Including the commands described in the above) are stored in a predetermined area of the RAM 203, and the timer values of the various timers are reduced (step S190). In step S180, the main control unit 200 determines a command of a necessary mode and event according to the game control with reference to the command data table area 202, and stores digital information indicating the determined mode and event in the RAM 203 in a predetermined manner. Store in area.

Next, in step S195, the start port operating solenoid 300 and the special winning port operating solenoid 302 are driven in order to open and close the special winning opening 106 and the opening / closing member 120 of the special symbol starting opening 104 in a predetermined pattern. Then, in step S220, a prize ball setting process for outputting control information for causing a prize ball payout device (not shown) to perform a payout operation is executed. Further, in steps S230, 240, and 250, a game (not shown) External information processing for outputting various game data to the machine management device, a display lamp control process for storing a command for lighting control of the lamp display devices 110 and 112 in accordance with a game state in a predetermined area of the RAM 203, sound effect generation Device 11
6 executes a sound effect process for storing a command for controlling the sound effect generation in a predetermined area of the RAM 203 in correspondence with the game state.

Next, in step S260, R
The data stored in the AM 203 is output to the corresponding device via the output port 215 (port output process), and the device that receives the data performs a control operation based on the data. Then, a strobe signal is first output to the special symbol display device 100, and the mode and event data stored in the RAM 203 in step S180 are transmitted as shown in FIG. As a result, for example, the commands shown in FIGS. 6 to 9 are transmitted from the main control unit 200 to the special symbol display device 100 and received.

In step S270, the reset circuit 21
The reset standby process is executed until the reset signal is input from Step 3, and when the reset signal is input, the process shifts to Step S110 to continue the gaming machine control. Note that the reset standby processing includes updating of the above-described various random number generation counters and a predetermined winning number selection random number counter 1700 described later.

Next, the operation of the CPU 1020 of the special symbol display device 100 having received the command will be described with reference to FIG. First, in step S1100, the CPU 1020 sets its own stack pointer,
Initialization of the RAM 1090, initialization of the RAM 1090 itself, and the like are performed, and in step S1102, it is determined whether a new command has been input. When it is determined that a new command for display control has been input, (Y
es) The process proceeds to step S1104, while otherwise (No), the process proceeds to step S1110.

In step S1104, in the interrupt processing described with reference to FIG.
Copies the received command to the RAM 1090, and checks whether the command is normal or not. Next, CPU1
020 determines the start address of a processing table (not shown) in order to obtain a necessary command for performing fine display control independently of the main control unit 200. Then, in step S1108, the image processing LSI 1060 The data in the necessary area of the RAM 1090 is updated in order to output the data to the RAM 1090.

Next, in step S1110, RA
Based on the symbol control data set in M1090, scroll data to be output to the image processing LSI 1060 is obtained and set in the RAM 1090, and the symbol display position is set. Then, in step S1112, the symbol speed control is performed. Necessary data is stored in the program ROM
It is obtained from a speed table (not shown) built in the 1040 and set in the RAM 1090, and then the step S
At 1114, the symbol offset value is updated based on the speed data, and preparations are made for performing symbol fluctuation at the set speed.

Next, in step S1116, RA
Animation data is acquired from an animation processing table (not shown) storing the animation processing data set in M1090, and preparation for displaying a background image is performed.
Set in P output buffer, output enable flag is "1"
It is determined whether or not this is the case (step S1118).

If the output permission flag is not "1" (No), the process returns to step S1102 to repeat a series of processes, while the output permission flag is "1" (Ye).
In step S1120, the data set in the VDP output buffer is transferred to the image processing LSI 106 in step S1120.
Output to 0. The image processing LSI 1060 acquires the data in the character ROM 1180 and develops the image in response to this. The developed data is temporarily stored in the video RAM 1080 and then sent to the LCD panel interface circuit 1100 to be sent to the LCD panel 1120. Is displayed. In this way, at the set display position on the special symbol display device 100, the symbol variation display at the set speed, the display of the background image, and the like are performed.

FIG. 13 and FIG. 14 are explanatory diagrams of an example of the transmission timing of a command transmitted from the main control unit 200 to the special symbol display device 100, and the transmission command. When a predetermined condition such as a game ball winning in the special symbol starting port 104 is satisfied, the unit 200 first transmits a command for starting a symbol variation and specifying a variation pattern (). A command for designating a left stop symbol is transmitted after a lapse of T1 time (), and a command for designating a middle stop symbol is transmitted after a lapse of T2 time (), and a right stop symbol is designated after a lapse of T3 time. (), And after the elapse of T time from the start of the fluctuation, a command () for stopping all the symbols is transmitted. Before receiving the command, the CPU 1020 of the special symbol display device 100 performs fine display control such as a change in the fluctuation speed to perform a series of fluctuation display control, and ends the fluctuation display control after a lapse of T time from the start of the fluctuation. I do.

(Features of the Present Invention) (Structure) As shown in FIG. 20, a V-zone winning detection unit 2000 is connected to the main control unit 200 in addition to the structure of FIG. The V zone winning detection unit 2000 is a specific area (not shown) in the special winning opening 106 (also referred to as a V zone).
Is configured to output a high-level signal when a game ball wins. FIG. 21 is an explanatory diagram showing an output example of this output signal. In this case, a high-level signal is output twice in accordance with two V zone winnings. Therefore, the main control unit 200 controls the V zone winning detection unit 2000.
By counting the number of times that the output signal has become high level, the number of winnings in a specific area can be grasped.

At the time of a big hit, the special winning opening operating solenoid 320 is driven and controlled to open the big winning opening 106 so that the winning sphere can be discarded. When the number of winning balls counted reaches the specified number of winnings, the large entrance 106 is closed to make it impossible to win. On the other hand, at the time of the opening control, if a prize of more than the required prize set in accordance with the specified prize is performed for the specific area, the continuation condition is satisfied and the next opening operation is continued. The continuation is controlled so as to be performed at most 16 times in response to the occurrence of the big hit.

FIG. 16 is an explanatory diagram of the table 201 stored in the ROM 201. The table 201 stores a round, which is the number of times of release, a privilege flag, a privilege content, and data ΔTX for performing privilege grant determination in association with each other.

FIG. 17 shows an example of determining whether or not to give a privilege.
This will be described with reference to FIG. If three game balls are won within ΔTX after opening of the special winning opening 106, a privilege flag is set to give a privilege. On the other hand, grand prize mouth 1
If three game balls are not won within ΔTX after the release of 06, no privilege flag is set. And this Δ
Since TX has a different value from a1,..., A15 for each round, the conditions for determining whether or not to set a privilege flag in each round are set to be different.

Another example of determining whether or not to give a privilege will be described with reference to FIG. In response to the opening of the special winning opening 106, a high timing pulse is generated three times at time TP1 and a low timing pulse is generated three times at time TP2. Stand up. On the other hand, in other cases, the privilege flag is not set. Although not shown in a table or the like, this TP
Since 1 has a different value set for each round, the conditions for determining whether or not to set a privilege flag in each round are set to be different.

As can be seen by referring to the table 1600 of FIG. 16, the different privilege contents for each round “opening time Δt1 extension, opening time Δt2 extension,
..., opening time Δt15 extension ”is set. Therefore, the privilege is provided as different for each round.

(Operation Example 1) Next, the operation will be described. FIG.
As shown in (1), in the first round (initial opening control), the main control unit 200 determines whether or not to grant a privilege, and sets a privilege flag 1 when granting a privilege. And the second
Since the privilege flag is set in the round, the opening time is extended by Δt1. At the same time, also in the second round, it is determined whether or not a privilege is to be granted, and if a privilege is to be granted, a privilege flag 1 is set. This privilege is given in the third round.

When such an operation is performed during the round continuation and it is assumed that the round reaches the fifteenth round, in the fifteenth round (control one time before the last round), the main control unit 200 gives a privilege. When it is determined whether or not to grant, and the privilege is to be granted, the privilege flag 1 is set. Since the privilege flag is set in the 16th round, the opening time is extended by Δt15.

Therefore, according to the operation example 1, the main control unit 2
In the case of 00, if a predetermined condition is satisfied at the time of the previous opening control, a privilege is given at the time of the next opening control, so that the playability during a large role can be further enhanced. In addition, the predetermined condition is made different for each number of times of opening (for each round), or the main control unit 200 gives a different privilege for each number of times of opening control (for each round), so that the game performance is further enhanced. Become like Further, the main control unit 200 synchronizes the timing pulse generated in response to the start of the opening control with the game ball prize winning in the opening special winning opening, that is, winning only when the timing pulse is at the high level. A novel game can be provided by setting a predetermined condition.

(Operation Example 2) An operation example 2 will be described with reference to FIG. In step S1800, the main control unit 20
A value of 0 refers to the table 1600 to determine whether or not all 15 privilege flags from round 1 to round 15 are on. If it is determined that all the privilege flags are not set (No), the process shifts to step S1810 to determine whether or not the privilege flags for the round 15 are set. If the privilege flag for the round 15 has not been set (No), the process ends. On the other hand, if the flag for the round 15 has been set (Yes), the process shifts to step S1820 to execute 16 as described in the operation example 1. The extension time during the round is extended by Δ15.

If the result of step S1800 is Yes, that is, if it is determined that all 15 privilege flags from round 1 to round 15 are on, the process proceeds to step S1830, where the privilege is provided in 16 rounds. Give. This benefit is considered to be most advantageous to the player among all benefits. For example, the extension time is set to Δ16 longer than Δt1 to Δt15, or the extension time is set to Δt15.
In addition, a privilege such as further increasing the number of pitches may be provided, or a completely different privilege, for example, automatically generating a big hit once or increasing a predetermined number of stored memories.

Therefore, according to the operation example 2, the main control unit 200 determines the predetermined condition set for each opening control from the first time (round 1) to one time before the last time (round 15). Are satisfied and 15 privilege flags are set, the last (16 round) privilege is given so as to be the most advantageous for the player. You can get involved in the game when you play a big role.

Although the embodiments of the present invention have been described above, various modifications and changes can be made to the above embodiments without departing from the spirit of the present invention. For example, predetermined conditions for determining the grant of a privilege are appropriately determined,
And the like.

As described above, according to the present invention,
If a predetermined condition is satisfied at the time of the previous opening control, a privilege is given at the time of the next opening control, so that the effect of further improving the playability in the role of a large role can be obtained.
