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. Thus, 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 process includes updating of the various random number generation counters described above.

Next, the operation of the CPU 1020 of the special symbol display device 100 that has 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

FIGS. 13 and 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. As can be understood from these drawings, the main control When a predetermined condition such as a game ball winning in the special symbol starting port 104 is satisfied, the unit 200 first issues a command for designating the time from the start of the symbol change to the stop of the symbol change. 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 after a lapse of T3 time A command for designating the right stop symbol is transmitted (), and a command () for stopping all the symbols after a lapse of T time from the start of the fluctuation is transmitted. The CPU 1020 of the special symbol display device 100 that has received the command performs a series of variable display control by performing fine display control such as a change in the changing speed before the time specified by elapses. After the elapse, the variable display control ends.

Next, FIG. 16 is a timing chart for explaining display control which is a first operation example of the present invention.
A first operation example of display control, which is a feature of the present invention, will be described with reference to FIG. 17 and the like, which are schematic explanatory diagrams showing how the display changes. These processes can be realized by appropriately setting and changing the data in steps S1110 to 1116 in FIG.

(First Operation Example) Now, as shown in FIG. 17A, the special symbol display device 100 has a left symbol, a middle symbol,
It is assumed that the right symbol is displayed as “2, 5, 4” in a horizontal row. In this state, if the main control unit 200 detects a winning start (FIG. 16A), the CPU 1020 of the special symbol display device 10 replaces only the left symbol with the probability variation symbol "7" and changes and displays the symbol (FIG. b)). And
Along with this change display, a change display of the middle symbol and the right symbol is started (FIGS. 16C and 16D). The display state at this time is as shown in FIG.

Next, the CPU 1020 executes the processing shown in FIG.
As shown in (d), the middle symbol and the right symbol are stopped and displayed in order. FIG. 17 (c) shows a display state when stopped and displayed with the middle symbol "7", and FIG. 17 (d) shows a display state when stopped and displayed with the right symbol "6". As a result, the result is “7
76 ", which is a loss.

Therefore, according to this operation example, the CPU
In step 1020, when a game ball is won, the left symbol is changed to a probability variation symbol and displayed, and the middle symbol and the right symbol are changed and then stopped and displayed. Therefore, a period from when the left symbol is replaced to when the middle symbol and the right symbol are stopped and displayed, that is, at least t1 (see FIG. 16).
During the period, the player can watch the symbols stop while having a sense of expectation. In addition, since the left symbol is changed and displayed with the probability variation symbol "7", it can be expected that the middle symbol and the right symbol are stopped so as to be in the probability variation state, and the sense of expectation further increases. In this operation example, “7” is adopted as the probability variation symbol, but as illustrated in FIG. 18, other odd variation symbols such as “1”, “3”, “5”, “9”, etc. May be adopted.

(Second Example of Operation) This example of operation will be described with reference to FIG. 19 which is a timing chart for explaining display control, and FIG. 20 which is a schematic explanatory view showing how the display changes. explain. Now, as shown in FIG. 20A, it is assumed that the left symbol, the middle symbol, and the right symbol are displayed in a horizontal line as “2, 5, 4” on the special symbol display device 100. In this state, if the main control unit 200 detects a winning start (FIG. 19A), the CPU 1 of the special symbol display device 10
In step 020, the left symbol and the middle symbol are replaced with the probability variation symbol "7" to be changed and displayed (FIG. 19B). And
At the same time as the change display, the right symbol change display is started (FIG. 19C). The display state at this time is shown in FIG.
It becomes as shown in.

Next, the CPU 1020 stops and displays the right symbol as shown in FIG. FIG. 20 (c) shows a display state when stop display is performed with the right symbol "7". As a result, the result is "776", which is a miss.

Therefore, in this operation example, CP
When a game ball is won, U1020 changes the left symbol and the middle symbol to the probability variation symbol and displays the symbol, and also displays the variation of the right symbol and then stops and displays the symbol. Therefore,
From when the left symbol and the middle symbol are determined to when the right symbol is stopped and displayed, it is possible to watch the symbol stop while having a sense of expectation. In addition, since both the left symbol and the middle symbol are changed and displayed with the probability variation symbol "7", the expectation that the right symbol can be stopped so as to be in the probability variation state is further increased. In this operation example, “7” is used as the probability variation symbol, but other probability variation symbols “1”, “3”, “5”,
An odd symbol such as "9" may be adopted.

As described above, in the embodiment of the present invention, the CPU 1020 first sets the main control unit 2
When 00 detects a start winning, at least one of the three symbols displayed in a horizontal row is changed to a predetermined symbol and displayed. Next, the symbols other than the changed symbol are stopped and displayed after the variable display. Therefore, the changed and displayed symbol is immediately determined, so that the appearance of the remaining symbols can be watched with a sense of expectation. Then, when the CPU 1020 changes and displays a symbol such as a probability variation symbol that is in an advantageous gaming state for the player, the remaining symbols are changed to be in an advantageous gaming state for the player. It can be expected to stop, so the sense of expectation will further increase.

In the operation example described above, the case where the replacement symbol "7" is different from the replacement symbol is described for the sake of easy understanding of the invention. It goes without saying that the symbol stopped and displayed with the symbol may be replaced with an advantageous symbol by the player to increase the player's expectation.

Various modifications can be made to the above-described embodiment of the present invention without departing from the gist of the present invention. For example, in the first operation example, the left symbol is a target to be changed and displayed by replacing the symbol, but the middle symbol and the right symbol may be subjected to the symbol replacement, and also in the second operation example, the middle symbol is also used. Needless to say, the right and left symbols, or the left and right symbols may be replaced. In the above description, a pachinko machine has been particularly described as an example, but the present invention may be applied to other types of gaming machines such as pachislot machines.
