Can be added. Further, in the case of a slot machine having a function of charging a plurality of medals inserted from the medal insertion section 4, the bet number is continuously set by the bet button 5 without inserting medals for each game. You can play the game.

Next, a start lever 6 serving as a start operation section is provided.
By operating the start lever 6 after a bet is made by the bet button 5 as described above or after a medal is inserted from the medal insertion unit 4, the reel drive unit 17 causes the reels 2a, All of 2b and 2c rotate simultaneously, and the game is started.

The stop button 7 serving as a stop operation section is provided with stop buttons 7a, 7b, 7c for each reel 2. The stop button 7a stops the left reel 2a, and the stop button 7b is The reel 2b is stopped, and the stop button 7c can stop the right reel 2c.

The control unit 10 detects the timing at which the stop button 7 is pressed, and controls the reel driving unit 17 to stop the rotation of the reel 2.

The internal structure and control method of the control unit 10 will be described in more detail. The control unit 10 is a storage unit that stores a CPU 11 that performs various arithmetic processes including random number generation control, a program that controls random number generation control and lottery, and a prize winning data table that is referred to at the time of lottery. ROM
12, a random access memory (RAM) 13 serving as a temporary storage unit, a random number generation unit 14 that receives an operation timing from the CPU 11 and outputs a random number to the CPU 11, and a medal insertion unit 4, a bet button 5, a start lever 6, and a stop button 7. It has an input port 15 for inputting a signal relating to the operation timing to the CPU 11, and an output port 16 for outputting a predetermined signal from the CPU 11 to the effect display unit 8a, the effect sound unit 8b, the reel drive unit 17, and the medal payout unit 18. ing.

The control unit 10 reads a random number from the random number generation unit 14 in accordance with a random number generation control program in the ROM 12, and performs a lottery or the like according to the read random number. Here, random number generation control by the control unit 10 will be described with reference to FIG. FIG. 3 shows the random number generation unit 14.
2 shows the internal configuration of the device.

The random number generation section 14 generates generation strings 141a, 141b, 141 for generating different random number generation strings.
c based on a latch signal from the CPU 11 and a generated column generator 141a, 141b,
Latch unit 142 including latch units 142a, 142b, 142c for latching random numbers from the generated sequence for each 141c
And the latch unit 1 based on a selection signal from the CPU 11.
And a switching output unit 143 for switching and outputting the random numbers latched by the switches 42a, 142b and 142c.

Further, the generation column generation unit 141
When the seed value, which is the random number initial value of the random number generation sequence, is set by the seed value setting signal from the CPU, the random number generation sequence corresponding to the seed value setting signal changes. The seed value is
This is the random number initial value of the random number generation sequence. Here, for the explanation of the seed value, for example, the random number generation sequence starts from “1”, then increases by one and increases to “256”, then returns to 1 again, and again. Consider a generation sequence that increases by one and goes around.

In this generation column, for example, the seed value is set to “1”.
Is set, "256" is set as described above.
Repeats the tour in increments of 1 until the seed value is "1"
When the setting of “0” is performed, the number starts from “10”, increases by “1” to “256”, returns to “1” again,
One more increment to "10" and "256"
And then repeat the same tour. That is, the seed value is the initial value of the random number generation sequence. Therefore, CPU1
When the seed value is set by the seed value setting signal from 1, the generation sequence becomes a generation sequence starting from the set seed value.

The latch unit 142a latches a random number from the generated sequence generated from the generated sequence generating unit 141a according to the timing of the latch signal. Further, the latch unit 142b latches a random number in accordance with the timing of a latch signal from the generated sequence generated from the generated sequence generating unit 141b, and the latch unit 142c converts the latch signal from the generated sequence generated from the generated sequence generating unit 141c. According to the timing
Latch a random number. Therefore, each latch unit 142 holds the random number latched at the timing of the input of the latch signal from the generation column from the generation column generation unit 141.

In the present embodiment, the seed value setting signal and the latch signal from the CPU 11
Although the signals are individually supplied to the latch 41 and the latch unit 142 so that they can be independently controlled, the signals may be commonly supplied to the entire generation column generation unit 141 and the entire latch unit 142.

The selection signal supplied to the switching output unit 143 is output from the CPU 11 based on the timing at which the operation unit where an artificial operation is performed is operated. For example, when the timing at which the operation unit is operated is in a preset period A, the random number of the latch unit 142a is selected and output. The random number of 142b is selected and output, and when the period C is set in advance, the random number of the latch unit 142c is selected and output.

In this embodiment, the operation unit includes
There are a medal insertion unit 4, a bet button 5, a start lever 6, a stop button 7, and the like. In the medal insertion part 4, it is the timing when a medal is inserted, in the bet button 5, it is the final bet timing, and in the start lever 6, it is the start operation timing,
For the stop button 7, it is the stop operation timing.

When a random number is generated from the random number generator 14 as described above, the random number is output to the CPU 11. CPU
In 11, a lottery of a prize is performed by comparing the generated random number with a prize data table by a random number generation program stored in the ROM 12.

For example, if the random number is 2 from "1" to "256"
When there are 56 types of random numbers, consider a case where the predetermined winning data table is in the range of “10” to “15”.
If the generated random number is "10", it matches the winning data table, and therefore, the winning is achieved. However, if the generated random number is "1", it does not match the winning data table. So it does not win.

When a winning lottery is performed by the control unit 10 as described above, the presence or absence of an internal winning (inside win) in the slot machine 1 is determined according to the lottery result. Then, when the stop operation of the reel 2 is finally performed by the stop button 7, the rotation of each reel 2 is stopped, and the three reels 2 a, 2 b, and 2 c arrange the symbols in three rows and three columns.

If, for example, a lottery is won and a predetermined symbol is arranged on the bet line, medals having a predetermined number of medals according to the symbol sequence are sent from the medal payout unit 18 to the medals. It is paid out to the medal tray 9 via the outlet 9a.

At the same time as the payout of medals or at an arbitrary time during the game, images and sounds for game effects are output from the effect display unit 8a and the effect sound unit 8b, which are effect information notification units. Is done. In the effect display unit 8a and the effect sound unit 8b, the effect method is as follows.
Can be changed by the random number output from. The above is the description of the configuration of each unit and the random number generation control in the slot machine 1.

Next, the operation of the random number generation control in the control unit 10 will be described with reference to FIGS. First, a medal insertion operation is performed from the medal insertion unit 4 by the player of the slot machine 1 (step 1). Then, a bet operation for setting the bet number is performed by the bet button 5 (step 2).

Next, when the start lever 6 is operated,
The CPU 11 detects the operation timing of the start lever 6 (step 3). Then, a winning lottery process is performed based on the operation timing (step 4). Here, the winning lottery process in step 4 will be described with reference to FIG.

Each generated sequence generator 141 of the random number generator 14
Each of a, 141b, and 141c has a different random number generation sequence circulating therein, and each of the latch units 142a, 142b, and 142c.
latch the random number from the generated sequence by c (step 4)
0). The latch timing may be latched at the same time as the operation timing of step 4 or may be latched at a predetermined timing according to the operation timing.

When latched in step S40, the latches 142a, 142b and 142c are in a state where random numbers are latched. In this state, a selection signal for selecting any one of the random numbers latched by the latch unit 142 is calculated by the CPU 11 based on the operation timing detected in step 3, and the switching output unit 14 is selected.
3 (Step 41).

Then, the switching output section 143 outputs a random number selected from the latch sections 142a, 142b and 142c to the CPU 11 based on the selection signal (step 4).
2). For example, the random number selected and output here is the random number A latched by the latch unit 142a.

The CUP 11 compares the random number A output from the switching output unit 143 with the winning data table (step 43), thereby determining an internal winning lottery and completing the winning lottery (step 44). ).

Then, returning to step 5 in FIG. 4, a first effect is performed. Here, the effect means that an image or sound for a game effect is output from the effect display unit 8a or the effect sound unit 8b under the control of the CPU 11. The type of the image and the sound (the type of the effect) is determined by the CPU 1
1 can be switched, for example, CPU
At 11, the effect can be switched by making it correspond to the random number output from the random number generator 14.

In the first effect, an effect corresponding to a random number different from the random number A output from the random number generator 14 in step 42 is performed. Specifically, at the time of the first effect, first, the CPU 11 outputs a selection signal to the switching output unit 143, and switches the random number latched by the latch unit 142. For example, it switches to the random number B latched by the latch unit 142b and outputs it. And the CPU 11
Then, the effect display unit 8a and the effect sound unit 8b are controlled so as to perform an effect corresponding to the random number B. In addition, the effect corresponding to the random number is determined in advance.

After the first effect in step 5, the rotation of all the reels 2 is started by the reel drive unit 17 (step 6). Then, when the player operates any of the stop buttons 7 for stopping any of the reels 2 (step 7), a second effect is performed (step 8).

At the time of the second production, the stop button 7
Is output from the CPU 11 to the switching output unit 143 of the random number generation unit 14 to switch the random number latched by the latch unit 142. For example,
The random number C latched by the latch unit 142c is switched and output. Then, the CPU 11 controls the effect display unit 8a and the effect sound unit 8b so as to perform an effect corresponding to the random number C.

Then, the reel 2 is stopped by the reel drive unit 17 corresponding to the stop button 7 (step 9). Next, it is determined whether all the reels 2 have stopped (step 10), and steps 7 to 9 are repeated until all the reels have stopped. Further, when the operation of the stop button 7 is not performed, control is performed to stop the reel 2 for a predetermined time after the rotation is started.

When all the reels 2 are stopped, a third effect is performed (step 11). The third effect is an effect corresponding to a random number different from the random number C output from the random number generator 14 at the time of the second effect. During the third stage,
A selection signal is output from the CPU 11 to the switching output unit 143,
The random number latched by the latch unit 142 is switched. For example, the CPU 11 switches to the random number A latched by the latch unit 142a and outputs the random number A, and the CPU 11 causes the effect display unit 8a and the effect sound unit 8 to perform an effect corresponding to the random number A.
control b.

Since all the reels 2 have stopped rotating,
When the winning symbols are lined up on the bet line, medals are paid out to the medal tray 9 from the medal payout unit 18 (step 12). The above is the operation of the random number generation control in the present embodiment.

In the winning lottery process in step 4 of the random number generation control operation, the random number can be changed after changing the random number by changing the seed value of the random number generation column. Hereinafter, with reference to FIG. 6, a description will be given of a random number change by changing a seed value. Note that the seed value can be changed for each of the occurrence column generation units 141a, 141b, and 141c. However, here, the change of the seed value of the occurrence column generation unit 141a will be described for the sake of explanation.

In step 3, since the CPU 11 detects the operation timing of the start lever 6, the CPU 11 controls the change of the seed value based on the detected operation timing (step 45). To change the seed value, the seed value is changed according to the operation timing.
For example, the seed value may be changed to a preset seed value such as α, β, γ, or the like, or the added value may be changed in accordance with the operation timing, and the changed added value may be added to the seed value. By doing so, the seed value may be changed.

The seed value may be changed by adding the random number output from the random number generator 14 just before to the seed value. Further, the seed value may be changed by switching the random number latched by the latch unit 142 according to the operation timing, changing the random number to another random number, and adding the other random number to the seed value.

Then, so as to obtain the changed seed value,
A seed value setting signal from the CPU 11 is generated by the generation column generation unit 141.
And when the seed value is set, the generation column is changed according to the set seed value (step 46). Next, the latch unit 142 latches a random number in accordance with the timing of the latch signal (step 47), and the latched random number is output from the switching output unit 143 (step 4).
8).

Note that, as in the present embodiment, the generated sequence generation unit 14
When there are a plurality of 1s and latches 142, the CPU 11 may output a switching signal to the switching output unit 143 to switch a plurality of random numbers latched by the latches 142.

The CUP 11 is connected to the switching output unit 143
By comparing the random number output from the above with the winning data table (step 49), the internal winning lottery is determined and the winning lottery is completed (step 50). The above is the operation of the random number generation control in the case of the random number change by changing the seed value in the winning lottery process.

In the winning lottery process of the present embodiment, the random number is changed in accordance with the operation timing of the start lever 6. In step 5, the random number may be changed in accordance with the operation timing finally bet. Furthermore, the random number may be changed by a combination of the operation timing of the start lever 6, the insertion timing of the medal insertion unit 4, the operation timing of the bet button 5, and the like.

In the winning lottery process and the first effect,
Although the random number is changed by switching the random number, in the first effect, the random number may be changed according to the insertion timing of the medal insertion unit 4 or the operation timing of the bet button 5. Further, in the second effect and the third effect, the random number is changed by switching the random number. In the third effect, the random number is changed depending on the insertion timing of the medal insertion unit 4 and the operation timing of the bet button 5.
The random number may be changed.

In this embodiment, an example is shown in which the random number generator is applied to a lottery of a slot machine. However, any other gaming machine having an operation section to which an artificial operation can be added may be used. It may be a game machine,
It may be a game machine.

[0069]

According to this random number generator, even if the cyclic update timing of a certain random number generation sequence is known due to the use of an unauthorized device, the random number is changed according to the artificial operation timing. Therefore, it is possible to provide a random number generating device capable of generating a random number with higher randomness.

Further, for example, when a lottery is used in a lottery in a slot machine of a gaming machine, and a lottery of a prize and a lottery of an effect method of performing an effect by display or sound are performed as an example, Since the random numbers can be changed by the output timing of each random number for the winning lottery and the production method lottery, there is no relevance (independence) between the winning and the production method lottery and each lottery Randomness can be improved.

Further, since the random number can be changed by switching the random number generation sequence from among the plurality of random number generation sequences, the random number can be generated by switching to a completely different random number generation sequence. Also, the random number can be changed by changing the initial value of the random number of the generated sequence, that is, by changing the starting point of the generated sequence in the generated sequence.

Further, the operation unit for performing an artificial operation is as follows:
A medal insertion operation unit for inserting medals, a bet operation unit for setting the number of medals to be bet, a start operation unit for starting a game,
Since the operation unit is at least one of the stop operation units for stopping the game, the random number can be changed according to the operation timing of any operation unit that is an artificial operation. In addition, since the random number is changed by at least one of the operation units, it is possible to generate a random number with higher randomness.

Since the present invention can be applied to a winning lottery or a lottery method, it is possible to enhance the randomness in each lottery.
