Abstract

PROBLEM TO BE SOLVED: To facilitate the forcible display of a stop pattern in order to change a pictorial pattern mechanically, when a variable display part is embodied as a rotor such as a drum or a belt. SOLUTION: When it is assumed that the command 'assign a variation speed to 10 ms/step' sent from a main board in timing (2) has not been normally received by CPU for display control, the variation cannot be stopped with a pictorial pattern of a pattern number(n), in case the CPU for display control receives the command 'stop the variation with the pattern of the pattern number(n)' in timing (4). In this case, the CPU for display control calculates the time required for the variation to be continued so that the pictorial pattern of the pattern number(n) comes to a display position, when the variation is continued at the n-assigned variation speed. Further, a motor drive circuit is made to continue the variation for the calculated time and when the calculated time is over, a command to stop the pictorial pattern is given to the motor drive circuit.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine such as a pachinko game machine or a coin game machine, and more particularly to a game machine including a variable display device whose display state can be changed, wherein a display result on the variable display device is predetermined. The present invention relates to a gaming machine in which a predetermined game value can be given when the display mode is changed to the display mode.

[0002]

2. Description of the Related Art As a gaming machine, a variable display device having a variable display section for variably displaying symbols is provided, which is advantageous to a player when the display result of the variable display section has a predetermined specific display mode. There is one configured to shift to a gaming state. The variable display device has one or more variable display units, and is generally configured to display the display results of the plurality of variable display units at different times. On the variable display section, for example, a plurality of identification information such as numbers and symbols are variably displayed.

[0003] When the display result of the variable display section for displaying a special symbol is a combination of a predetermined specific display mode, it is usually called a "big hit". In addition, the game value is a right to make the state of the variable prize ball device provided in the game area of the gaming machine advantageous for a player who is easy to win a hit ball, or a right for the player to be in an advantageous state. Or to generate.

[0004] When a big hit occurs, for example, a big winning opening is opened a predetermined number of times, and the state shifts to a big hit game state in which a hit ball is easy to win. Then, in each open period, when a predetermined number (for example, 10) of winning prizes is won, the winning prize opening is closed. The number of opening of the special winning opening is fixed to a predetermined number (for example, 16 rounds). An opening time (for example, 29.5 seconds) is determined for each opening, and if the opening time elapses even if the number of winnings does not reach a predetermined number, the winning opening is closed. If the predetermined condition (for example, winning in the V zone provided in the special winning opening) is not satisfied at the time when the special winning opening is closed, the big hit gaming state ends.

[0005] In addition, among the combinations of display modes other than the "big hit" combination, at a stage where some of the display results of the plurality of variable display portions have not been derived and displayed yet, the display results have already been derived and displayed. A state in which the display mode of the variable display unit that satisfies the display condition that is a combination of the specific display modes is referred to as “reach”. If the display result of the identification information variably displayed on the variable display unit does not satisfy the condition of “reach”, the result is “out” and the variable display state ends. A player plays a game while enjoying how to generate a big hit.

In such a gaming machine, a stop symbol of the identification information is determined before the change starts. That is, the stop symbol is already determined before the change of the identification information starts. Then, a fluctuating operation (a fluctuating period or a fluctuating speed) is instructed to the display control means by a predetermined command from the game control means for controlling the progress of the game, and a stop symbol is notified at a predetermined timing. Then, if an error occurs in the command instructing the fluctuating operation notified from the game control means to the display control means, the fluctuating mode controlled by the display control means is different from the original fluctuating mode, and the fluctuating stop instruction is given by the display control means. In some cases, when the stop symbol is received, the determined stop symbol cannot be displayed. In such a case, in a gaming machine having a variable display portion which is electrically controlled to be displayed, such as a CRT or an LCD, the symbol is replaced by replacing the symbol so that the final stop symbol becomes a predetermined stop symbol. be able to. However, in a gaming machine having a variable display section using a mechanical rotating body such as a drum or a belt, it is difficult to replace symbols. That is, an incorrect stop symbol is displayed.

[0007]

As described above, when the symbol variation control is performed via the display control means, an error is made in the symbol display control when a command is not correctly transmitted to the display control means. Can occur. For example, there is a case where it is impossible to stop with a stop symbol. In such a case, if the symbol display is performed electrically, for example, a stop symbol can be forcibly displayed, but the continuity of the variable display is interrupted and suddenly discontinuous identification information is inserted, It can give the player an unnatural impression and a suspicious feeling. Further, when the variable display unit is realized by a rotating body such as a drum or a belt, it is difficult to forcibly display a stopped symbol because the symbol is mechanically changed.

Therefore, according to the present invention, even when a command is not correctly transmitted from the game control means to the display control means, the symbol can be reliably stopped at the symbol designated by the game control means. It is intended to provide a gaming machine.

[0009]

A gaming machine according to the present invention comprises:
Including a variable display device whose display state is changeable, starting a change of identification information displayed on the variable display device according to satisfaction of a condition for starting the change, and displaying a display result of the identification information in a predetermined display mode Is a gaming machine that can provide a predetermined game value to the player when becomes, a game control means for controlling the progress of the game, and a display control means provided separately from the game control means The display control means performs the fluctuation control of the identification information according to the fluctuation speed designation command sent from the game control means, and uses the identification information designated when the identification information stop command is received from the game control means. If the fluctuation cannot be stopped, the apparatus is configured to include a correction display control unit that stops the fluctuation with the specified identification information by changing the fluctuation time.

[0010] The correction display control means may be configured to change the identification information at the change speed based on the change speed designation command received immediately before the identification information stop command during the change of the change time. Here, the period of change of the fluctuation time is a period from the end of the normal fluctuation period to the end of the extended period when the fluctuation period is extended from a regular value.

[0011] The correction display control means may be configured to fluctuate the identification information at high speed during the period of changing the fluctuation time. Here, the high speed is a high speed at which stop order of the plurality of pieces of identification information does not change from a predetermined order.

[0012] The correction display control means may be configured to fluctuate the identification information in the same direction as the fluctuation direction of the immediately preceding identification information during the fluctuation time change period.

[0013] The game control means may be configured to transmit only a command relating to the change at the time of a change of the display such as the time of switching of the identification information change speed.

FIG. 10 is an explanatory diagram showing display control command data transmitted from the main board 331 to the display control board 380. As shown in FIG. 10, in this embodiment, the display control command data includes display control signals CD0 to CD0.
The signal is transmitted from the main board 331 to the display control board 380 through eight signal lines of the CD 7. In addition, a signal line or the like of a display control signal INT for transmitting a strobe signal is also provided between the main board 331 and the display control board 380.

FIG. 11 is a timing chart showing an example of transmission timing of display control command data given from the main board 331 to the game control board 380. In this example, each display control data (1 byte) constituting the display control command data is transmitted every 2 ms as shown in FIG.

FIGS. 12 to 17 are explanatory diagrams showing examples of display control command data relating to symbol variations given from the main board 331 to the display control board 380. FIG. As shown in the drawings, in this embodiment, the basic circuit 353 of the main board 331 sets the fluctuation speed of the left and right
Display control board 380 with display control command data of byte
To instruct. In this example, since the variable display unit is realized by the rotating drums 122A to 122C driven by the stepping motors, the basic circuit 353 indicates the rotation speed of the stepping motor 200, thereby indicating the symbol changing speed. .

The display control command data is composed of a 1-byte mode indicating a rough operation and 1-byte external data indicating a specific fluctuation speed. That is, mode = 81H: indicates normal rotation or stop of the left symbol. Mode = 82H: reverse rotation of the left symbol. Mode = 83H: Stop of left symbol and stop symbol are shown. Mode = 84H: indicates normal rotation or stop of the right symbol. Mode = 85H: shows reverse rotation of the right symbol. Mode = 86H: Stop of right symbol and stop symbol are shown. Mode = 87H: Indicates normal rotation or stop of the middle symbol. Mode = 88H: shows reverse rotation of the middle symbol. Mode = 89H: shows the stop of the middle symbol and the stop symbol.

The external data indicates a specific speed or symbol number. As is clear from the description of FIGS. 12 to 17, the display control command data relating to the symbols transmitted from the main board 331 to the display control board 380 is a command for specifying the fluctuation speed itself. Therefore, at each switching time of the symbol fluctuation speed, the display control command data designating the fluctuation speed after the switching is transmitted from the main board 331. Then, according to such a command system, the basic circuit 353 of the main board 331 only needs to send out display control command data specifying the change speed after switching at each switching point, and control of command creation and sending is performed. It has been simplified.

In this example, each of the left and right middle symbols has 20 types. The display control command data includes
There is display control command data for instructing the blinking of the drum lamp 151 in addition to the data related to the symbols.

In addition to determining whether to make a big hit or not, a stop symbol displayed on the variable display device 26 is determined. The display control board 380 is sequentially provided with display control command data corresponding to the change speed, and the decoration control board 8 is provided.

In the symbol display area, the symbol is changed for 6.800 seconds according to the change pattern a, as shown in FIG. Then, after 6.800 seconds elapse, the symbol is changed for 0.900 seconds according to the change pattern b.

If the basic circuit 353 determines that a jackpot is to be generated based on the winning start, or that the jackpot is not to be reached but is reached, the display control CPU
The step 381 controls the stepping motor 200 in accordance with the command data from the basic circuit 353 so that the left and right symbols are changed as shown in FIGS.

Then, the “left” in the variable display device 26
In the symbol display area, as shown in FIG. 20A, first, the symbol is changed for 5.000 seconds according to the change pattern a.

As shown in FIG. 20C, in Reach 1, in the “medium” symbol display area of the variable display device 26, the symbol is changed for 6.800 seconds according to the change pattern a. When 6.800 seconds elapse, the 19-33 symbols fluctuate over 6.106-12.406 seconds according to the fluctuation pattern c. In the fluctuation pattern c, the fluctuation speed gradually decreases, and thereafter changes at a constant speed.
This is a pattern in which the fluctuation is performed at a constant speed that fluctuates at a higher speed.

In Reach 2, in the "medium" symbol display area of the variable display device 26, the symbol is varied for 6.800 seconds according to the variation pattern a. further,
The symbol fluctuates according to the pattern a for 6.000 seconds, and then fluctuates for 0.600 seconds according to the fluctuation pattern d. The fluctuation pattern d is a pattern in which the fluctuation speed is gradually reduced to stop the fluctuation. During this time,
Twelve symbols are changed.

In Reach 3, in the "medium" symbol display area of the variable display device 26, the symbol is changed for 6.800 seconds according to the change pattern a. Subsequently, the fluctuation is performed for 5.656 seconds according to the fluctuation pattern d. Further, the fluctuation by the fluctuation pattern a is performed with the symbol temporarily stopped for 0.300 seconds, and thereafter, the fluctuation is performed for 5.656 seconds according to the fluctuation pattern d.

In Reach 4, after the fluctuation is performed in the same manner as in Reach 1, the fluctuation of the symbol for 0.380 seconds is stopped from the timing (R) shown in FIG.
The fluctuation is performed according to the fluctuation pattern f for 0 seconds. The fluctuation pattern f is a fluctuation pattern of a constant speed that fluctuates at a high speed, and changes 14 symbols in 1.050 seconds.

In Reach 5, after the fluctuation due to the frame feed is performed, the timing (R) shown in FIG.

In this embodiment, FIGS. 19 and 20
In each of the timings at which the speed switching is necessary in each of the fluctuation patterns shown in (1), display control command data indicating the rotation speed of the stepping motor 200 according to the switching speed after the switching is transmitted from the main board 331 to the display control board 380. FIG. 21 is a timing chart showing specific transmission of display control command data. (B) shows an example of the time relationship of each timing shown in (A),
(C) shows the speed of the stepping motor 200 and the number of steps (movement amount) at that speed in each period. Note that the number of steps (movement amount) indicates how much the stepping motor 200 rotates until the display control board 380 receives the next display control command data. It is not information to be notified.

The example shown in FIG. 21 is an example at the start of the change of the middle left and right symbols. As shown in FIG. 22, in this example,
First, the display control command data (commands 81H, 0A) of "designating the variation speed of the left symbol to 20 ms / step (forward rotation)" is sent from the main board 331 to the display control board 380.
H) is transmitted. Then, "the fluctuation speed of the right symbol is 20
ms / step (forward rotation) "display control command data (commands 84H, 0AH), and display control command data (command 87H, 0AH specifying the fluctuation speed of the middle symbol as 20ms / step (forward rotation)". ) Are sequentially transmitted. In the display control board 380, when the display control CPU 381 receives the display control command data, the display control CPU 381 instructs the motor drive circuit 363 to give a pulse of a frequency such that the stepping motor 200 rotates at a rotation speed according to the content. give.

In motor driving circuit 363, pulse generating circuit 410 generates a four-phase pulse signal having a frequency corresponding to the designated speed. The transistors 421 to 424 are turned ON / OFF by these pulse signals. O is generated by the pulse signal from the pulse generation circuit 410.
A current determined by the drive voltage and the resistances R1 to R4 of the drive coil flows through the drive coils L1 to L4 (see FIG. 5) connected to the transistor in the N state, and the drive coil is excited. Therefore, the stepping motor 200 rotates at a speed according to the frequency of the pulse signal. Since the stepping motor 200 is connected to the rotating drums 122A to 122C, the rotating drums 122A to 122C rotate at a speed according to the frequency of the pulse signal.

The display control command data is transmitted by 1 byte every 2 ms, and one display control command data is 2 bytes.
As shown in FIGS. 21A and 21B, the right symbol starts to fluctuate with a delay of 4 ms from the fluctuation start timing of the left symbol, and the middle symbol is 4 ms from the fluctuation start timing of the right symbol, as shown in FIGS. Start to fluctuate with a delay (FIG. 21 (A)
Timing).

When 40 ms elapses from the timing, the basic circuit 353 of the main board 331 displays the display control command data (commands 81H and 08H) of “designating the variation speed of the left symbol to 16 ms / step (forward rotation)”. 380 (the timing of FIG. 21A). Next, "The fluctuation speed of the right symbol is set to 16 ms / ste.

1 (A) timing). In the display control board 380, when the display control CPU 381 receives the display control command data, the display control CPU 381 generates a pulse having a frequency such that the pulse rotates at a rotation speed according to the content thereof.
Is given to the motor drive circuit 363 as given by As shown in FIG. 21 (C), the stepping motors 200 for changing the middle left and right symbols each have 16
20ms / s before switching to ms / step speed
Rotate 2 steps in step.

Further, when 32 ms elapses from the timing, the basic circuit 353 sets “the fluctuation speed of the left symbol to 10 m
s / step (forward rotation) ”display control command data (commands 81H and 05H).
(The timing of FIG. 21A). Then
Display control command data (commands 84H, 0H) of "designating the fluctuation speed of the right symbol to 10 ms / step (forward rotation)"
5H) and "The fluctuation speed of the middle symbol is 10 ms / step.
The display control command data (command 87H, 05H) of "designate (forward rotation)" is sequentially transmitted (timing in FIG. 21A). In the display control board 380, when the display control CPU 381 receives the display control command data, the display control CPU 381 instructs the motor drive circuit 363 to give a pulse of a frequency such that the stepping motor 200 rotates at a rotation speed according to the content. give. As shown in FIG. 21 (C), each of the stepping motors 200 for varying the middle left and right symbols has a speed of 10 ms / ste.
Before switching to speed p, 2ms at 16ms / step
Rotate step.

As described above, although there is a command transmission / reception delay of 4 ms, each of the stepping motors 200 for changing the middle left and right symbols simultaneously takes 20 ms / step →
16ms / step → 10ms / step → ...
Increase the rotation speed. As a result, FIG. 19 and FIG.
As shown by the variation pattern a, the variation speed of the symbol gradually increases.

FIG. 23 is an explanatory diagram showing an example of a speed change when the symbol is stopped. This example is an example in which the fluctuation speed is gradually reduced to stop. In FIG. 23, the stop of the middle symbol is taken as an example, but the left and right symbols are similarly controlled. For example,
When the stepping motor 200 is rotating at 6 ms / step, the display control board 38
0, the display control command data (command 87) of “designating the fluctuation speed of the medium symbol to 10 ms / step (forward rotation)”.
H, 05H) is transmitted (timing in FIG. 23). CPU 3 for display control of display control board 380
81 is a motor drive circuit 363 according to the command.
Then, an instruction is given to rotate the stepping motor 200 at 10 ms / step.

At the timing shown in FIG. 23, display control command data (commands 87H and 08H) of “designating the fluctuation speed of the middle symbol to 16 ms / step (forward rotation)” is transmitted from the basic circuit 353 of the main board 331.
At the timing, the basic circuit 353 transmits display control command data (commands 87H, 0AH) of "designating the fluctuation speed of the medium symbol to 20 ms / step (forward rotation)". Display control CPU 38 of display control board 380
1 gives an instruction to the motor drive circuit 363 according to the command.

At the timing shown in FIG. 23, from the basic circuit 353, the display control command data (“Stop the fluctuation of the middle symbol with the symbol of symbol number 3”) (command 89H, 03
H) is assumed to have been transmitted. Then, the display control board 380
The display control CPU 381 gives the motor drive circuit 363 an instruction to stop the medium symbol. In the motor drive circuit 363, the pulse generation circuit 410 stops the pulse generation according to the stop instruction. Therefore, the rotation of the stepping motor 200 for changing the symbol stops, and as a result, the symbol change stops. Such a symbol stop is performed, for example, as shown in FIG.
20 and the fluctuation pattern d of the reach 2 shown in FIG.

In this embodiment, the rotating drum 122A
Drum sensor 139 for performing symbol position adjustment based on the reflected light from the reflecting portion provided at ~ 122C.
, And a signal from the drum sensor 139 is input to the display control CPU 381 via the sensor input circuit 176. Therefore, the display control CPU 381 can finely adjust the stop position based on the signal from the sensor input circuit 176. That is, the rotating drum 122A
Control is performed so that the stepping motor 200 rotates several steps so that the output of the drum sensor 139 becomes a normal value (a value output at a normal symbol stop position) when the rotation of ~ 122C is stopped.

FIG. 24 is a diagram showing a state in which the fluctuation speed of the medium symbol transmitted from the main board 331 at the timing is 16 ms.
/ Designate command (command 87H, 08H) is normal in the display control CPU 381 due to noise on the cable between the main board 331 and the display control board 380. FIG. 7 is an explanatory diagram showing an example in which the information is not received. As shown in FIG. 23, the stepping motor 2
The rotation speed of 00 should be switched to 16 ms / step, but in this case, the rotation continues at a speed of 10 ms / step.

Then, at the timing, 20 ms /
Even if the display control CPU 381 receives the display control command data (command 89H, 03H) of “stop changing the middle symbol in the symbol of symbol number 3” at the timing, the symbol number is switched. 3
The fluctuation cannot be stopped with the symbol of. Originally 16ms
This is because the symbol of symbol number 3 exceeds the stop position in the period (timing to timing) in which the speed should be changed at a slow speed of / step, because the speed fluctuated at 10 ms / step which is faster than that.

The display control CPU 381 can recognize the display symbol at the time of the start of the change.
From the fluctuation speed (specifically, the rotation speed of the stepping motor 200) specified by each display control command data and the reception interval of each display control command data, the fluctuation amount of the symbol can be recognized. Further, by detecting a signal from the drum sensor 139, it is possible to confirm how many symbols have changed. Therefore, based on such information, it is possible to know whether or not the display can be stopped at the designated symbol when display control command data instructing to stop the symbol is received.

In the example shown in FIG. 24, the display control CP
In U381, it can be seen that the symbol No. 3 cannot be fluctuated and stopped as the stop symbol. In that case, the display control CPU
381 calculates how long the fluctuation is continued when the fluctuation is continued at the fluctuation speed at that time and the symbol of symbol number 3 comes to the display position, and the motor driving circuit 363 continues the fluctuation for that time. Let it. Then, when the time has elapsed, a stop instruction of the symbol is given to the motor drive circuit 363.

As described above, the display control CPU 381
If it is detected that the designated symbol cannot be changed and stopped as a stop symbol, the change time is changed, that is, the change is continued to delay the change stop timing. That is, the drum is further circulated so as to be able to fluctuate and stop at the designated symbol, and then the circling of the drum is stopped so that the designated stopped symbol is displayed.

FIG. 25 is a diagram showing the state in which the fluctuation speed of the middle symbol transmitted from the main board 331 is 20 ms.
/ Control command (command 87H, 0AH) is normally received by the display control CPU 381 due to noise on the cable between the main board 331 and the display control board 380. It is explanatory drawing which shows the example which did not exist. Also in this case, when the display control CPU 381 receives the display control command data (commands 89H and 03H) of “stop the fluctuation of the middle symbol with the symbol of symbol number 3” at the timing, the CPU 381 changes with the symbol of symbol number 3. Can not stop. In a period (timing-timing period) that should originally fluctuate at a slow speed of 20 ms / step, it fluctuated at a faster speed of 16 ms / step.
This is because the symbol of symbol number 3 is beyond the stop position.

Therefore, the display control CPU 381 calculates how long the fluctuation is to be continued when the fluctuation is continued at the fluctuation speed at that time until the symbol of symbol number 3 comes to the display position, and calculates only the time. The motor drive circuit 363 keeps changing. Then, when the time has elapsed, a stop instruction of the symbol is given to the motor drive circuit 363.

As described above, the display control CPU 381
When the display control command data indicating the stop of the symbol is received from the basic circuit 353 of the main board 331, if it is detected that the designated symbol cannot be stopped as the stop symbol at that timing, the change time is changed. Corresponding. At this time, the fluctuation speed of the continued symbol fluctuation is the speed based on the display control command data received immediately before.
For example, in the example shown in FIG. 24, it is 20 ms / step by the command received at the timing, and in the example shown in FIG. 25, it is 16 ms / step by the command received at the timing. As described above, when the fluctuation is continued at the speed according to the display control command data received immediately before, only the management of how much time is required when the fluctuation is continued at the fluctuation speed at that time is designated. The symbol change can be stopped with the stopped symbol.

In the examples shown in FIGS. 24 and 25, since the display control CPU 381 cannot normally receive the display control command data, the display control CPU 381 operates at a higher speed in a period in which it should originally fluctuate at a lower speed. It is an example that it was not possible to stop at the specified stop symbol due to fluctuation, but conversely, it was not possible to stop at the specified stop symbol because it fluctuated at a slower speed during the period that should originally fluctuate at a high speed Also in this case, by making the fluctuation time longer than the original fluctuation time, the fluctuation can be stopped at the designated symbol. When the symbol to be stopped is beyond the stop position and the amount of the excess is small (for example, about one symbol), the adjustment is performed by changing the symbol in the direction opposite to the normal change direction. You may. By doing so, the original display result can be displayed in a shorter time.

FIG. 26 is a flowchart showing the operation of the display control CPU 381 for realizing the control shown in FIGS. 24 and 25. As shown in FIG. 26, the display control CP
Upon receiving the display control command data relating to the symbol change from the main board 331, the U381 checks whether the command is a command for designating the stop of the symbol (step S901). That is, it is confirmed whether the first byte of the display control command data is 83H, 86H or 89H. As described above, since the first byte of the display control command data is defined to be a mode instruction, it is easy to determine whether the command is a command for designating a symbol stop. If the command is not a command for designating the stop of the symbol, a pulse frequency corresponding to the variation speed of the symbol specified by the display control command data is calculated (step S903), and the frequency is output to the pulse generation circuit 410 of the motor drive circuit 363. (Step S904).

If the received display control command data is a command for designating a symbol stop, the display control CPU 3
81 recognizes which symbol is designated as the stop symbol (step S905). And a display control CPU.
Since the symbol 381 knows the symbol displayed at that time as described above, it can determine whether or not the change can be stopped with the designated symbol (step S90).
6). If it is determined that the stop can be performed, the stop position is finely adjusted based on a signal from the drum sensor 139 if necessary (step S907). An instruction to stop the pulse is issued (step S908).

When the display control CPU 381 determines that the variation cannot be stopped at the designated symbol, the variation is continued at the variation speed at that time based on the symbol currently displayed, as described above. In this case, it is calculated how long the fluctuation is continued until the designated stop symbol comes to the display position (step S909). Then, when the time has elapsed (step S910), an instruction to stop the pulse is issued to the pulse generation circuit 410 (step S91).
1).

The display control CPU 381 may monitor the transition of the display symbol based on the signal from the drum sensor 139 in order to more accurately detect the stop timing, in addition to the time monitoring in step S910. . Then, if necessary, the stop position may be finely adjusted based on a signal from the drum sensor 139.

In the examples shown in FIGS. 24 and 25, when it is determined that the stop cannot be made at the designated timing at the designated timing, the fluctuation is continued at the speed according to the display control command data received immediately before. However, when such a situation occurs when the left symbol or the middle symbol is stopped, if the variation is continued at the variation speed at that time, FIG. 19 and FIG.
Although the symbols must be stopped in the order of right and left as shown by 0, the stop order may be changed. Then, the player may feel strange or suspicious.

Therefore, if the stop order changes if the fluctuation is continued at the speed at that time, it is better to continue the fluctuation of the symbol at a high speed. Not only when the stop order is changed, but when it is determined that it is impossible to stop at the designated stop symbol, the symbol may be constantly changed at a high speed.

FIG. 27 is an explanatory diagram showing an example of a case where the symbols are continuously changed at high speed when it is determined that the stop cannot be made at the designated stop symbol. As shown in FIG. 27, the display control command data (commands 87H, 08) of “designating the fluctuation speed of the medium symbol to 16 ms / step (forward rotation)” sent from the main board 331 at the timing.
H) is not normally received by the display control CPU 381. In that case, the rotation speed of the stepping motor 200 is originally 16 ms / at the timing.
should be switched to step, in this case 1
The rotation continues at a speed of 0 ms / step.

Then, at the timing, 20 ms /
Although the rotation speed is switched to the step rotation speed, even if the display control CPU 381 receives the display control command data of “Stop changing the middle symbol at the symbol of the symbol number n” at the timing, the change is not changed at the symbol of the symbol number n. Can't stop. In the period (timing-timing period) which should originally change at a slow speed of 16 ms / step, the symbol of symbol number n exceeds the stop position because the speed fluctuated at 10 ms / step which is faster than that. is there.

Therefore, in this example, the display control CPU 3
When detecting that the fluctuation cannot be stopped in the symbol of the symbol number n, the 81 instructs the pulse generation circuit 410 of the motor drive circuit 363 to output a pulse having a frequency corresponding to, for example, 2 ms / step. Also, 2ms
When the fluctuation is continued at the rotation speed of / step, how long the fluctuation is continued until the designated symbol comes to the display position is calculated, and the motor drive circuit 363 is calculated for that time.
To continue the fluctuation. And after that time,
An instruction to stop the symbol is given to the motor drive circuit 363.

FIG. 28 is an explanatory diagram showing another example of a case where the symbols are continuously changed at a high speed when it is determined that it is impossible to stop at the designated stop symbol. In this example, the symbol is temporarily stopped, fluctuates at a constant speed of 8 ms / step, and then stops. For example, it corresponds to the fluctuation pattern f of the reach 4 shown in FIG.

Here, "the fluctuation speed of the middle symbol is to be received at the timing shown in FIG. 28 is 8 ms / step.
(Forward rotation) ”display control command data (command 87
H, 04H) are not normally received by the display control CPU 381. Then, the display control CPU 3
81 receives the display control command data of "stop the change at the symbol of the symbol number n" and detects that the change cannot be stopped at the timing at the symbol of the symbol number n. Accordingly, the display control CPU 381 instructs the pulse generation circuit 410 to output a pulse having a frequency corresponding to, for example, 2 ms / step, and for how long when the fluctuation is continued at the rotation speed of 2 ms / step. If the fluctuation is continued, it is calculated whether the designated symbol comes to the display position, and the motor driving circuit 363 continues the fluctuation for that time. Then, when the time has elapsed, a stop instruction of the symbol is given to the motor drive circuit 363.

FIG. 29 is a flowchart showing the operation of the display control CPU 381 for realizing the control shown in FIGS. 27 and 28. The processing in steps S901 to S908 is the same as the processing shown in FIG. However, in this case, if it is determined in step S906 that the fluctuation cannot be stopped at the designated symbol, the display control CPU 381 sets a high speed of, for example, 2 ms / step based on the symbol currently displayed. When the fluctuation is continued at the fluctuation speed, it is calculated how long the fluctuation is continued until the designated stop symbol comes to the display position (step S909). Then, it instructs the pulse generation circuit 410 of the motor drive circuit 363 to output a pulse corresponding to 2 ms / step (step S920).
Thereafter, when the calculated time has elapsed (step S91)
0), an instruction to stop the pulse is issued to the pulse generation circuit 410 (step S911).

As described above, when the display control command data indicating the stop of the symbol is received, if it is determined that the fluctuation stop cannot be performed at the timing at the specified stop symbol, the stop symbol is located at a position where the stop symbol can be displayed again. Continue to fluctuate at high speed until. Therefore, there is no possibility that the stop order in which symbols must be stopped in the order of right and left should be changed. In this example, the maximum speed is 2 ms.
Although / step is used, the symbol may be changed at a speed lower than 2 ms / step as long as the stop order of the left and right middle symbols does not change. Also in this case,
When the symbol to be stopped is beyond the stop position and the amount of the excess is small (for example, about one symbol), the adjustment may be performed by changing the symbol in the direction opposite to the normal change direction. Good.

As described above, according to each of the above-described embodiments, the display control CPU 381 of the display control board 380 is used.
However, when a symbol stop instruction is received from the basic circuit 353 of the main board 331, if it is detected that the fluctuation cannot be stopped at the specified stop symbol at that timing, the fluctuation time is designated differently from the regular time. Stop the fluctuation with the stopped symbol. Therefore, it is possible to prevent a symbol different from the stop symbol determined by the basic circuit 353 from being stopped and displayed, or from being displayed in a shifted state.

In each of the above examples, the case of the final stop of the symbol is taken as an example.
Also in the case of, when it is detected that the designated stop symbol cannot be temporarily stopped at the designated timing, the period of the variation pattern d in the reach 3 and the period of the variation pattern c in the reach 4 are changed to display the stop symbol. Is done.

In each of the above embodiments, the direction of change does not change in principle during the change continuation period for displaying the stop symbol. Therefore, for example, when it is detected that a temporary stop cannot be performed at the specified timing at the specified timing during the fluctuation in the fluctuation pattern that stops after the reverse fluctuation, such as the fluctuation pattern g in the reach 5 illustrated in FIG. The reverse fluctuation is performed during the fluctuation continuation period for displaying the stop symbol. Therefore, at the time of the correction display control for deriving the original display result, the display control does not become complicated and does not look unnatural to the player. However, as described above, when it is possible to display the stop symbol in a shorter time by changing the fluctuation direction, the fluctuation direction may be switched.

In the above embodiments, the drum type variable display device 26 has been described as an example.
It is not limited to such a method. If you have a variable display device in which the symbol change is performed by the stepping motor,
The present invention can be applied to a gaming machine having a variable display device of another type such as a belt type (a variable mechanism using a driving pulley and a belt stretched over the driving pulley and provided with identification information). Further, in each of the above embodiments, the case where the stepping motor is used has been described, but the motor is not limited to the stepping motor. A servo motor, a DC motor, or the like may be used. Further, the present invention can be applied to gaming machines such as slot machines and coin-type gaming machines.

In the above embodiment, the drum type variable display device 26 has been described as an example.
The present invention may be applied to a gaming machine having a variable display device such as a CD that can electrically display symbols. When the present invention is applied to a gaming machine having such a variable display device, when the fluctuation cannot be stopped at the designated stop symbol, a symbol replacement that may give an unnatural feeling to the player is performed. Without performing, the stopped symbol can be displayed in a state where the symbol variation is continued.

As described above, according to the present invention, the display control means provided separately from the game control means controls the game machine in accordance with the variable speed designation command sent from the game control means. If the fluctuation is not stopped with the specified identification information when the identification information stop command is received from the game control means, the correction display control means changes the fluctuation time. Is configured to stop the fluctuation with the identification information, which prevents the identification information different from the identification information determined by the game control means from being stopped and displayed, or from being stopped and displayed with the identification information shifted. effective.

When the correction display control means is configured to fluctuate the identification information at the fluctuating speed based on the fluctuating speed designation command received immediately before the identification information stop command during the fluctuating time change period, The fluctuation can be stopped by the specified identification information only by managing how long it takes to continue the fluctuation at the current fluctuation speed.

If the correction display control means is configured to fluctuate the identification information at high speed during the period of changing the fluctuation time, there is no danger that the original stop sequence of the identification information is changed, and the correction display control means is unnatural. Inconveniences such as a fluctuating change and a player feeling suspicious are avoided.

In the case where the correction display control means is configured to change the identification information in the same direction as the change direction of the immediately preceding identification information during the change time of the change time, the change is controlled by the specified identification information. The control to stop is not complicated.

When the game control means is configured to transmit only a command relating to the change at the time of the change of the display, the command system is simplified, and the control of command creation and transmission is simplified.
