DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine provided with a combination display device for producing a predetermined profitable operation by a predetermined combination.

[0002]

2. Description of the Related Art When a game ball passes a starting gate provided with a winning switch, the variable display is formed based on a ball detection signal from the winning switch. A variable symbol display device that starts and stops the symbol change and displays various combinations of symbols, and a special winning opening that is opened when each stopped symbol of the variable symbol display device is a predetermined combination. The one provided with is referred to as a "fever-type game machine", and various proposals have been made.

[0003]

In the above-mentioned symbol control of the variable symbol display device, each winning ball at the starting port is
Operate once. The time from the passing of the ball to the starting port to the first stop of the symbol after the start of the symbol change is determined in advance by a program of the central control unit MPU that controls the variable symbol display device. In this case,
When a plurality of game balls wins the starting port during one symbol change, the winning number is stored by the storage means,
After the end of one symbol change, the symbol is normally continuously changed again by the number of storages, usually up to four.

[0004] By the way, since four or more balls are not memorized as described above, even if more balls pass through the starting port, they are not memorized and become invalid balls. The limited number cannot be exhausted, the invalidation frequency increases, and the player is dissatisfied.

On the other hand, in order to eliminate the invalid ball, a stop switch manually operated by a player is provided on the front portion of the pachinko machine, and the symbol stop timing of the variable symbol display device is synchronized with the pressing operation of the stop switch. A configuration was also proposed in which the symbols were set in the variable symbol display device.Since the symbols in the variable symbol display device are changed in display content at a fixed cycle, if the player is skilled, the stop switch is operated from the time of operation. It is possible to learn the timing up to the stop point of the variable display, so that the stop symbol of the symbol display unit can be easily set to a desired stop symbol from the variable display repetition cycle and the operation timing. As a result, only players with excellent game skills can obtain excessive profits, which impairs the soundness of pachinko games, and Becomes the prize balls exceeding Dedama ratio significantly are paid out, a problem such as a game arcade is suffer great damage.

An object of the present invention is to eliminate such a problem of the conventional configuration.

[0007]

According to the present invention, a pachinko machine is provided with a setting timer which can be freely set by a player on a front surface of the pachinko machine. And timing control means for determining the time until the stop of the control based on the set time T _X by the setting timer.

At this time, assuming that an arbitrary upper limit time is T _L , a time from passing the starting opening to the start of symbol change is T ₀ , and a time from the start of symbol change to the start of symbol extraction is T _C , T ₀ ≧ T
_{When L} , T _C = T _X , and when T ₀ <T _L , T _C =
As T _L -T ₀ + T _X, since game ball passes through the start hole, first symbol in symbol variation after the start due to the starting opening passage may be determined amount of time before shutdown.

[0009] Further, an arbitrary limited number value up to the maximum storage number stored by the storage means is defined as M, and if there is a starting port passage memory of M or more, the game ball passes through the starting port and passes through the starting port. Thus, the time until the symbol first stops after the symbol change starts may be determined based on the set time T _X by the setting timer.

[0010]

[Action] based on the setting by the player setting the timer time T _X, since game ball passes through the start hole, first symbol after the start symbol variation is set the time to stop.

At this time, as described above, when T ₀ ≧ _TL due to passing memory digestion to the starting port, T _C = T _L
X , and when T ₀ <T _L , T _C = T _L −T ₀ + T _X
For example, if _{TL is set} to 5 seconds, the time from when the game ball passes through the starting port to when the symbol stops for the first time after the start of the symbol fluctuation is stored in the passing memory to the starting port. Whether or not there is, it is set to 5 seconds or more.

Further, by selecting the limited number value M, for example,
And enable only T _X if it is two or more pass memory, thereby prevents reduction of excessive downtime, it is possible to a certain time setting harmonious.

Next, the operation will be described with reference to FIGS.

FIG. 4 is a flow chart showing the procedure of the variation and stop processing of the variable symbol display device 6. First, the symbol variation time set by the setting timer 4 is set in step S1, and the starting port 13 is set in step S2. It is determined whether the winning switch has been turned on. If NO, the process proceeds to step S3, where the timer set by the setting timer 4 is cleared, and the process returns to step S1. At this time, a new timer change of the setting timer 4 can be accepted.
If YES, the timer set by the setting timer 4 is set, and the flow advances to step S4.

In this step S4, each of the variable indicators A, B, C of the variable symbol display device 6 starts to change, and the process proceeds to step S5, where the prize switch is turned on by passing the ball through the opening 13 during the symbol change. The number of passing spheres
Up to four winning prizes are stored by M. Then, it is determined in step S6 whether or not there is a memorized prize ball. If NO, the process proceeds to step S8, where a basic timer of the symbol fluctuation time programmed in advance is selected, and the basic time T
_b becomes effective, and the process proceeds to step S13. If YES, the process proceeds to step S7, where it is determined whether or not the number of storages is M or more.

Here, M indicates a limited number value consisting of an arbitrary value from 0 to 4 up to the maximum storage number as described later. If the number of storages is smaller than M by this selection, the process proceeds to step S8 to select the basic timer, thereby invalidating the set time T _X set by the setting timer 4 and setting the number of storages at an excessive speed. Try to prevent digestion.

If it is not less than the limit number value M, step S
Proceeding to 9, the timing control is performed. Figure 5 is a subroutine showing the timing control, select the setting timer has been set at S1, and enable the setting time T _X, to control time in step S10 to S12.

Here, assuming that an arbitrary upper limit time is T _L , a time from passing the starting opening to the start of symbol change is T _0, and a time from the start of symbol change to the start of symbol extraction is T _C , step S 10 It is determined whether or not T ₀ ≧ T _L. YE
In the case of S, T _C = T _X as in step S11. If NO, T _C = T _L − as in step S12.
_Let it be T ₀ + T _X.

[0030] The flow advances to step S13, the basic time T _b or time T _C of the above it is determined whether the timed digestion. If NO, the process returns to step S4, the process proceeds only to step S14 if YES, the probability A hit or miss is determined by the creation random counter, a stop symbol is determined by the symbol creation counter, and then a stop symbol creation process is performed. Then, the process proceeds to step S15, where the variable display A is stopped. Proceeding to step S16, the variable display B is stopped. In step S17, it is determined whether or not the variable display A and the variable display B are the same symbol (reach). If NO, the process proceeds to step S18, in which the variable display C is stopped in a normal manner. Proceed to step S22. If YES, the process proceeds to step S19, and the variable display C is stopped in a manner specific to reach, for example, to stop at a low speed. Then, the process proceeds to step S20, where a jackpot determination is made. If it is a jackpot, a jackpot process is performed in step S21 and the process proceeds to step S22. If it is off, the process proceeds to step S22. You. If NO, the process returns to step S1, and if YES, the process proceeds to step S23. After the elapse of the interval time, the winning memory is decremented by one in step S24, and the process returns to step S4.

As shown in the above-described flowchart, time control is performed in steps S7 to S13, and three types of patterns are generated by this control determination. This will be described in more detail with reference to FIG.

FIGS. 6A and 6B show the case where T _L is set to 5 seconds, and both cases are for the case where the number of storages ≧ M.
FIG. 6A shows a case where T ₀ ≧ 5. In this case, the set time T _X settings to T _C timer 4. Here, T _C is the time from the start of symbol fluctuation to the start of symbol extraction. That is, in step S14, a stop symbol is created by extracting from the random number in the storage device ROM. In response to the stop symbol, the symbol of the circulating variable display A is stopped after the T _C expires. You need to wait until the pattern matches. If this is the symbol extraction time T _N , the actual time from the start of the fluctuation to the stop is T _C + T _N. Here, rotate time (variation time for one symbol)
Is 61.452 ms, T _N = 61.452 × N (N: the number of symbols required until the symbol of the circulating variable display A reaches the stop symbol). Therefore, the actual stop time is not constant.

FIG.₀ <5. This
In the case of_C = T_L -T₀ + T _X And

FIG. 6C shows the case where the number of storages <M.

FIG. 7 shows a case in which this is actually applied from this relationship. Here, T _L = 5 seconds, T _X = 1.5 seconds, T _b
= 5.5 seconds, T _N = 2 seconds, and M = 2.

FIGS. 7A and 7B show the case where T ₀ = 3 seconds (<T _L ). FIG.
, Two pass memories are added, and a total of three pass memories (≧ M)
The timing control in the case of is shown. In this case,
2. T _C = T _L −T ₀ + T _X becomes effective, and after the start of fluctuation.
After 5 seconds, symbol extraction starts. FIG. 7B shows a case where the starting port 13 has passed (passing memory) when the symbols are sequentially changed by the passing memory, and there is no passing memory thereafter, and thus there is only one passing memory. In this case, symbol extraction is started after elapse of 5.5 seconds by selection of the basic timer.

FIGS. 7C and 7D show the case where T ₀ = 6 seconds (≧ T _L ), and FIG. 7C shows the case where there are a total of three passage memories after passing through the starting port 13 as in FIG. 7A. Show. In this case, T _C = T _X becomes valid, and symbol extraction is started after 1.5 seconds have elapsed. FIG. 7d shows, like FIG.
This is the case where there is no pass memory (pass memory) and no pass memory thereafter, and the symbol extraction is started after 5.5 seconds elapse by selection of the basic timer.

As can be understood from the result, when the number of stored passages is not more than the limit number M, the setting timer 4
Set time T _X is invalid. For this reason, the progress is accelerated only when there is a predetermined storage number, and the occurrence of invalid balls due to four or more winning storages is reduced. Therefore, the rapid progress of the game can be adjusted by setting the limited number value M, and proper memory and digestion can be performed. Further, by making the limit number value M selectable by the game arcade, it is possible to make the game progress state optimal for the game arcade.

Further, by setting the condition of _TC , from the passage of the starting port 13 to the start of symbol extraction, in this example, 5
Seconds or more can elapse, preventing excessive progress,
A harmonious driving mode of the variable symbol display device 6 becomes possible.

[0040]

According to the present invention, the pachinko machine is provided with a setting timer which can be freely set by a player on the front portion, and the game ball passes through the starting port, and the symbol stops after the symbol change starts for the first time. Is determined based on the set time T _X by the setting timer. Therefore, it is possible to shorten the symbol variation time, promote the consumption of the stored number, and pass through the starting port. Even if it is not stored, the occurrence of invalid balls can be reduced. Further, the timing control by the player becomes possible, and the willingness to participate in the pachinko game can be satisfied. In addition, the setting timer adjusts the stop timing later,
Since it is not possible to synchronize with the repetition period of the variable display, there is no possibility that only a player having excellent game technology will obtain excessive profit.

On the other hand, assuming that an arbitrary upper limit time is T _L , a time from passing the starting opening to the start of symbol change is T ₀ , and a time from the start of symbol change to the start of symbol extraction is T _C , when T ₀ ≧ T _L T _C = T _X, T at the time of _{T 0 <T L C = T} L
−T ₀ + T _X , after the game ball passes through the starting port,
In the case where the time until the symbol first stops after the start of the symbol change caused by the passing of the starting opening is determined,
The time from when the game ball passes through the starting port until the symbol stops for the first time after the start of the symbol change is maintained for a predetermined time or more even if there is no passing memory to the starting port. This makes it possible to prevent undesired progress and to achieve a harmonious driving mode of the variable symbol display device 6.

Further, an arbitrary limited number value is defined as M, and M
In the case where the above-mentioned opening opening passage memory is stored, the time from when the game ball passes through the opening opening until the symbol stops for the first time after the start of the symbol change is set to the set time T _X by the setting timer.
In this case, an excessively short stop time can be prevented, and a harmonious time can be set.
