FIG. 13 and FIG. 14 are explanatory diagrams of an example of the transmission timing of a command transmitted from the main control section 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 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, an operation example of the present invention will be described by employing a special symbol display device 100 as an example of a peripheral device. FIG. 15 is an explanatory diagram summarizing the operation outline of the gaming machine according to the embodiment of the present invention. In FIG. 15, “〇” indicates that the display control command was received without transmission failure, and “×”
Indicates that the display control command is not received due to transmission failure (command missing). Accordingly, case 0 indicates a normal case where each command is normally received.

(Case 0) In this case, no command is lost. The operation of the CPU 1020 will be described with reference to the timing chart of FIG. The CPU 1020
Receiving the fluctuation pattern designation command, the game machine starts the symbol fluctuation in the special symbol display device 100 and turns off the left symbol fluctuation signal, the middle symbol fluctuation signal, the right symbol fluctuation signal, and the symbol fluctuation signal. Level (for example, 0
(V)) and output to the tester as an ON level (for example, 5 (V)) (FIGS. 16 (f) to (i)). Next,
Upon receiving the left symbol designation command, the middle symbol designation command, and the right symbol designation command, the left symbol data, the middle symbol data, and the right symbol data designated by these commands are output to the tester upon receiving the command ((FIG. 16 (l) ~
(N)). When the symbol stop command is received, the symbol determination signal (FIG. 16 (j)) is output from the OFF level to the ON level (for 100 msec) to the tester, and the left symbol changing signal, the middle symbol changing signal, Right symbol changing signal and symbol changing signal are turned off from ON level
Output to tester as level. At this time, in the gaming machine, the stop display at the designated symbol is performed in the display area of the special symbol display device 100. In this case 0, since no command omission has occurred, the symbol display device error signal (FIG. 16 (k)) remains OFF level.

(Case 1) In this case, the first command and the third command are normally received, and a command missing occurs in at least one of the second commands. In this example, it is assumed that the left symbol designating command is missing as shown by reference numeral A in FIG.

Referring to the timing chart of FIG.
The operation of the PU 1020 will be described. The CPU 1020 receives the change pattern designation command, starts the symbol change in the gaming machine, and sets the left symbol change signal, the middle symbol change signal, the right symbol change signal, and the symbol change signal from the OFF level to the ON level. ((F)-(i) of FIG. 17). Next, when the left symbol designation command is missing and the middle symbol designation command and the right symbol designation command are received, the middle symbol data and the right symbol data designated by these received commands are output to the tester upon receiving the command. At the same time, the data of the left symbol of the previous appearance is output to the tester as the left symbol ((FIG. 17 (l)-
(N)).

When a symbol stop command is received,
Turn the symbol confirmation signal (Fig. 17 (j)) from OFF level to ON
The signal is output to the tester as a level (for 100 msec) and the symbol display device error signal (FIG. 17 (k)) is
The FF level is output to the tester as the ON level, and the left symbol change signal, the middle symbol change signal, the right symbol change signal, and the symbol change signal are output from the ON level to the OFF level to the tester. At this time, in the display area of the special symbol display device 100, a stop display of the designated symbol is performed for the middle symbol and the right symbol, and the left symbol of the previous symbol is stopped and displayed for the left symbol.

Therefore, in this case 1, the CPU 1
020, when the fluctuation pattern designation command and the symbol stop command are received, and when the three symbol designation commands, which are the number to be transmitted, are not received, it is determined that at least one command omission has occurred in the symbol designation command. to decide. Then, instead of the symbol to be originally displayed by the missing command, the symbol of the previous appearance is displayed in the special symbol display device 100.
Is displayed on the display area, and a symbol display device error signal indicating that a command drop has occurred in the tester is output to the tester at the ON level upon receipt of the symbol stop command. The symbol is also displayed so that there is no problem in data collection, and the tester can grasp that a symbol missing command is generated in the symbol designating command by outputting the symbol display device error signal.

(Case 2) In this case, the symbol stop command (and in some cases at least one of the symbol designation commands) is not received. The operation of the CPU 1020 will be described with reference to the timing chart of FIG. In this example, as shown by a symbol B, it is assumed that the symbol stop command is missing, and the variation pattern designation command and all symbol designation commands are not missing.

The CPU 1020 receives the change pattern designation command, starts the symbol change display in the gaming machine, and sets the left symbol change signal, the middle symbol change signal, the right symbol change signal, and the symbol change signal to the OFF level. ON
Output to the tester as a level (FIG. 18F)
(I)). Next, a left symbol designation command, a middle symbol designation command, and a right symbol designation command are sequentially received, and the left symbol data, the middle symbol data, and the right symbol data designated by these received commands are output to the tester ((FIG. 18 (l) ~
(N)).

Since the symbol stop command cannot be received due to transmission failure, the CPU 1020
Instead of stopping the fluctuation display by the symbol stop command, the fluctuation display is stopped after the lapse of the elapsed time (T) specified by the fluctuation pattern designation command, and the appearance display is performed. When the time T has elapsed, the symbol determination signal (FIG. 18 (j)) is output from the OFF level to the ON level to the tester, and the symbol display device error signal (FIG. 18).
(K)) is output from the OFF level to the ON level as an ON level to the tester.

In FIG. 18, it is assumed that the symbol designating command is not missing. However, when at least one symbol designating command is missing, as shown in Case 1, the missing symbol is designated. The symbol corresponding to the designated command may be displayed in the display area of the special symbol display device 100 as the previous result, and the symbol data may be output to the tester.

Therefore, in this case 2, the CPU 1
In step 020, when the fluctuation pattern designation command and the three symbol designation commands to be transmitted are received, and the symbol stop command is not received, it is determined that a command missing has occurred in the symbol stop command. Then, when the time designated by the variation pattern designation command has elapsed, the symbol variation display in the display area of the special symbol display device 100 is stopped, and a signal indicating that the symbol stop command is missing is output to the tester.

On the other hand, if a variation pattern designation command and a symbol designation command of less than three, which is the number to be transmitted, are received and a symbol stop command is not received, a symbol designation command and a symbol stop command are received. It is determined that a command missing has occurred, and when the time designated by the variation pattern designation command has elapsed, the symbol variation display in the display area of the special symbol display device 100 is stopped, and the symbol to be originally displayed by the missing symbol designation command The special pattern display device 10 replaces the previous pattern with
0 is displayed in the display area, and a symbol display device error signal is output to the tester.

Therefore, in case 2, if the variation pattern designation command and the symbol designation command are normally received, the symbol variation display is stopped even if the symbol stop command is missing, so that there is no problem in data collection. In addition, the tester can recognize that a command omission has occurred in the symbol stop command when an error signal is output. Further, even if a part of the symbol designating command is not received, the symbol of the previous appearance is displayed in the display area of the special symbol display device 100, so that there is no trouble in data collection, and the symbol error signal of the symbol display device is transmitted to the tester. The tester can recognize that a command missing has occurred in the symbol designation command and the symbol stop command that are output.

(Case 3) In this case, a variation pattern designating command (and at least one of the symbol designating commands in some cases) is not received. FIG.
The operation of the CPU 1020 will be described with reference to the timing chart of FIG. In this example, it is assumed that, as indicated by reference numeral C, a variation pattern designation command is missing, and all symbol designation commands and symbol stop commands are not missing.

CPU 1020 first receives a left symbol designating command. At this time, it is determined that the variation pattern designation command to be received first is missing. At this point, the symbol variation display is started, the left symbol data designated by the received left symbol designation command is output to the tester, and the symbol display device error signal is output from the OFF level to the ON level to the tester. In addition, since the fluctuation pattern designation command is not received, the left symbol fluctuation signal, the middle symbol fluctuation signal, the right symbol fluctuation signal, and the symbol fluctuation signal are OF.
It remains at the F level (FIGS. 19F to 19I).

Next, the middle symbol designating command, the right symbol designating command, and the symbol stop command are received in order, and the variable display is stopped at the designated symbol, and the symbol stop signal is received for 100 (msec). Only the ON state.

In FIG. 19, it is assumed that the symbol designating command is not missing. However, if at least one symbol designating command is missing, as shown in case 1, the missing symbol is designated. The symbol corresponding to the designated command may be displayed in the display area of the special symbol display device 100 as the previous result, and the symbol data may be output to the tester.

Therefore, in this case 3, the CPU 1
In step 020, when a symbol designating command is received first, it is determined that a command missing has occurred in the variation pattern designating command. Then, when the symbol designating command is received, a stop display is performed in the display area of the special symbol display device 100, and a symbol display device error signal indicating that a command missing of the variable pattern designating command has occurred is sent to the tester. Since output is performed, even if a command missing in the fluctuation pattern specification command occurs, stop display is performed and there is no problem in data collection, and a symbol display device error signal is output and a command loss occurs in the fluctuation pattern specification command This can be understood with a tester.

Although not assumed in FIG. 19, the CP
If U1020 further receives a symbol designating command that is less than three, which is the number to be transmitted, U1020 determines that command omission has occurred in the symbol designating command. Then, instead of the symbol to be originally displayed by the missing symbol designation command, the symbol of the previous appearance is displayed on the display area of the special symbol display device 100, and a symbol display device error signal indicating that the symbol designation command missing has occurred. Is output to the tester, in the case shown in FIG. 19, even if the symbol designating command is further lost, the previous roll is displayed in the display area of the special symbol display device 100, so that there is no trouble in data collection. The tester can recognize that a command omission has occurred in the symbol designating command.

The operation of the CPU 1020 will be described with reference to the timing chart of FIG. In this example, as indicated by reference numerals D, E, F, and G, it is assumed that a variation pattern designation command, a left symbol designation command, a middle symbol designation command, and a right symbol designation command are missing.

After first receiving the symbol stop command, the CPU 1020 determines that the fluctuation pattern designation command, the left symbol designation command, the middle symbol designation command, and the right symbol designation command are not received. In this case, upon receipt of the symbol designating command, all symbols are stopped and displayed as the symbols of the previous appearance, and these symbol data are output to the tester (FIGS. 20 (l) to (n)). The symbol display device error signal is changed from the OFF level to the ON level and output to the tester, and the symbol determination signal is set to the ON level only for 100 (msec). In this case 4, since the variation pattern designation command is not received, the left symbol variation signal, the middle symbol variation signal, the right symbol variation signal, and the symbol variation signal remain at the OFF level (FIG. 20).

Then, when the symbol stop command is received, the symbol to be displayed by the missing symbol designation command is displayed in the display area of the special symbol display device 100 instead of the symbol to be displayed, and the symbol display device is displayed. The error signal is output to the tester, so even if the fluctuation pattern designation command and the symbol designation command are missing, the last pattern is stopped and displayed, and there is no trouble in data collection. The lack of the command of the pattern designation command and the design designation command can be grasped by the tester.

(Case 5) In this case, a variation pattern designation command and a symbol stop command (and at least one of the symbol designation commands in some cases) are not received. The operation of the CPU 1020 will be described with reference to the timing chart of FIG. In this example, as shown by reference numerals H and I, it is assumed that the variation pattern designation command and the symbol stop command are missing and the symbol designation command is not missing.

CPU 1020 first receives the left symbol designating command. At this time, it is determined that the variation pattern designation command to be received first is missing. At this point, a symbol display device error signal is output to the tester. Next, the middle symbol designation command and the right symbol designation command are sequentially received, but the symbol stop command is not received. Therefore, in the display area of the special symbol display device 100, the designated symbol is designated by each designated command after a lapse of a predetermined time after receiving the right symbol designation command. The displayed symbol is stopped and displayed. In this case 4, since the variation pattern designation command is not received, the left symbol variation signal, the middle symbol variation signal, the right symbol variation signal, and the symbol variation signal remain at the OFF level (FIG. 20 (f)). )
-(I)).

In FIG. 18, it is assumed that the symbol designating command is not missing. However, if at least one symbol designating command is missing, as shown in case 1, the missing symbol is designated. The symbol corresponding to the designated command may be displayed in the display area of the special symbol display device 100 as the previous result, and the symbol data may be output to the tester.

Therefore, in this case 5, the CPU 1
When the symbol designation command is received first and the symbol stop command is not received thereafter, 020 determines that a command missing has occurred in the variation pattern designation command and the symbol stop command. Then, the symbol designated by the received symbol designation command is displayed on the display area of the special symbol display device 100, and the symbol display indicating that the command missing has occurred since the symbol designation command was first received. Since the device error signal is output, even if the variation pattern designation command and the symbol stop command are missing, the symbol is displayed in the display area of the special symbol display device 100, and there is no trouble in data collection, and the symbol display device error signal is output. The lack of the first variation pattern designation command and the symbol stop command can be grasped by the tester.

Although not assumed in FIG. 21, the CP
If U1020 further receives a symbol designating command that is less than three, which is the number to be transmitted, U1020 determines that command omission has occurred in the symbol designating command. Then, instead of the symbol to be originally displayed by the missing symbol designation command, the symbol of the previous appearance is displayed on the display area of the special symbol display device 100, and a symbol display device error signal indicating that the symbol designation command missing has occurred. Is output to the tester, in the case shown in FIG. 21, even if the symbol designation command is further lost, the previous roll is displayed, so that there is no problem in data collection, and the command loss occurs in the symbol designation command.
