Abstract

<P>PROBLEM TO BE SOLVED: To provide a game machine with which randomness and impartiality are kept in a big hit. <P>SOLUTION: A counter IC 14 is a 16-bit counter which counts-up whenever a clock pulse outputted from 7.15909 MHz count clock 14a falls and which is updated within the range of '0' to '65535'. The value of the counter IC 14 is read by an MPU 11 when the value of a random number counter 13b is not properly held owing to a backup fault, or the like, or cleared by the depression of a clear switch 30c. A random value is generated on the basis of the read value of the counter IC 14 and the random value is set as an initial value for updating the random number counter 13b. Thus, the initial value for updating the random number counter 13b is prevented from becoming a fixed value so that randomness and impartiality are kept in the big hit. <P>COPYRIGHT: (C)2003,JPO

Starts updating the random number counter with the value
The initial value of the update is a fixed value (here,
"0"), and the randomness of the random number counter decreases.
Was invited. Therefore, in the pachinko machine P of the present invention,
The update of the random number counter 13b is performed by the processing described below.
An initial value is randomly generated, and the random number counter 13b
To prevent the randomness from decreasing. That is, after the processing of S51, first, the counter

3e (S53). Note that the counter IC 14
As described above, the count value is the transient characteristic at power-on.
Time has passed since the power was turned on
Even if it is acquired at the specified timing, it changes each time it is acquired
Will be a random value. Therefore, in S52, "0"
~ Update (count up) within the range of "65535"
The count value of the counter IC 14 is randomly acquired.
In S53, the randomly acquired value (“0”)
To “65535”) is the initial value setting memory 13

The value of the initial value setting memory 13e is stored in the random number counter 13b.
(Correction) to a value within the update range of. Specifically,
The value of the initial value setting memory 13e is equal to or less than "630".
Or not, that is, with the value of the update range of the random number counter 13b.
It is confirmed whether or not there is (S55). Initial value setting memory 1
If the value of 3e is “631” or more (S54: No),
It exceeds the value of the update range of the random number counter 13b. Yo
In this case, from the value in the initial value setting memory 13b,
"630", that is, the value of the update range of the random number counter 13b
(S55) of subtracting the upper limit value (maximum value) of
Then, the value of the initial value setting memory 13e is set to a random number.
Processing (correction) to a value within the update range of the counter 13b
(S54, S55). On the other hand, in the process of S54, an initial value is set.
If the value of the memory 13e is equal to or less than “630” (S54:
Yes), a value within the update range of the random number counter 13b.
You. Therefore, in such a case, the initial value setting memory 13e
To the random number counter 13b and the current initial value memory 13c.
Write (S56, S57), random number counter 13b and
The update initial value is set in the current initial value memory 13c. What
Note that the random number counter 13b performs the processing in S56.
Set value (current initial value memory 13e after processing (correction))
Value) as the initial value of the update,
(S16, see FIGS. 4 and 7) to update the first cycle
Is started. As described above, the updating of the random number counter 13b is performed.
The initial value includes the count value of the counter IC 14 (that is, the initial value).
The random value written in the term value setting memory 13e)
Random value generated by processing (correction) is set
You. The value of the random number counter 13b due to a backup failure or the like
Is not properly held or the clear switch 30
Pressing c clears the value of the random number counter 13b
In this case, the random number
Since the update of the counter 13b is started, the random number counter
Update of the counter 13b is started from a fixed value such as "0".
To reduce the randomness of the random number counter 13b.
Can be suppressed. Here, for example, the main control board C and another board
(For example, power supply board 30), etc.
For example, a so-called "hanging board")
A signal illegally generated from the board (for example, power failure signal 3
An illegal act of outputting 1) to the main control board C is conceivable.
For example, the power failure signal generated illegally is continuously
When the power is output to C and the power failure process occurs frequently, the main control board
C (MPU 11) must execute the power failure process normally
And the game state is initialized (RAM 13 is initialized
). In this way, the random count
Update of the data 13b from a fixed value such as "0"
This unduly reduces the randomness of the counter 13b.
You. However, according to the gaming machine P of the present invention, the random number
The initial value of the update of the counter 13b is the transient characteristic at power-on.
Value (counter)
Randomly generated based on the IC14 count value)
You. Therefore, the person who commits the wrongdoing (illegal board)
The detection signal of the seed start switch 20 is incorrectly generated,
The detection signal generated illegally is output at the timing of jackpot
Even if you try to determine the value of the random number counter 13b
You can't create a jackpot
Can not. Therefore, a so-called “hanging substrate”
Also prevent fraudulent acts such as unreasonably generating jackpots
You can do it. Further, the jackpot determination is updated asynchronously.
Counter (random number counter 13b, counter IC1
Determined based on 4). That is, the jackpot determination value
Is 2 ms (the operating clock 11a of the MPU 11 has a frequency
Since it is 8.192 MHz, at 16,384 clocks
(Can be generated) based on the value of the random number counter 13b updated every time
At the beginning of the update of the random number counter 13b.
The value is 7.15909 MHz count clock 14a
(Cannot generate an interval of 2ms)
It is calculated (generated) based on the value of the counter IC14.
Therefore, the wrongdoer (illegal board) is the random number counter.
When operating in synchronization with the update cycle of the
Unable to grasp the count value of counter IC14,
Conversely, it operates in synchronization with the update cycle of the counter IC 14.
In this case, the value of the random number counter 13b can be grasped.
I can't. Therefore, the illegal board is the two count values 13b,
Because you cannot grasp 14 at the same time,
To further suppress unfair acts such as unfairly occurring
You can do it. It is to be noted that an illegal board executes an instruction in software.
Let's grasp jackpot judgment value by executing software control
If so, the software control should follow
Of counter IC14 with pulse that is too fast to perform
Has been performed, the incorrect board
(Count value of the counter IC 14)
I can't. Therefore, in this case, the counter IC 14
The count clock 14a is set to the operation clock 11 of the MPU 11.

You can do it. As described above, the main control board C and the other
(For example, power supply board 30) etc.
Illegal board (eg, so-called “hanging board”)
Etc.), the game state is initialized (the RAM 13 is initialized)
When the random number counter 13b is updated to “0” or the like,
Starting from a fixed value, the randomness of the random number counter 13b
May be unduly reduced. However, the second

Thus, the update can be continuously executed. Yo
And the person who commits the wrongdoing (illegal board)
The count value of 104 could not be determined,
As a result, as in the case of the first embodiment, the random number counter 13b
Unable to know the value, so illegally hitting the jackpot
They cannot live. Therefore, Iwayu
The jackpot is unreasonably generated by the "hanging board"
It is also possible to prevent fraudulent acts such as making them misbehave. Here, the clear terminal of the counter IC 104
Is fixed at +5 V, and the counter IC 10
4 cannot be initialized. So, the count
The IC IC 104 counts up when an error occurs.
In this case, it is performed continuously without being initialized.

Therefore, any improper act is given to this lithium battery
To prevent the count value of the counter IC 104 from being incorrect.
It can be prevented from being initialized. Next, a third embodiment will be described with reference to FIG.
Will be explained. Count value acquired from count IC 14
Is set to the initial value of the update of the random number counter 13b,
The count value exceeds the update range of the random number counter 13b.
In the first embodiment, if the count value is
By repeatedly subtracting the value (ie, “630”)
A value within the update range of the random number counter 13b was obtained (see FIG. 6).
See). On the other hand, in the third embodiment, the count value is divided by the predetermined value.
To obtain a value within the update range of the random number counter 13b.
Is configured. In addition, the same as the first embodiment described above.
The same reference numerals are given to the portions, and the description thereof will be omitted. FIG. 10 is a diagram showing a state in which the RAM of the main control board C is cleared.
And the third embodiment executed in the initialization process (S48).
Of the random number counter initial value setting process
It is. This processing is obtained from the counter IC14.
Process the count value to a value within the update range of the random number counter (
Correct) and update the processed value in the random number counter 13b.
By setting the initial value of
In the process to randomly generate the initial value of the update of 13b
is there. In this random number counter initial value setting process,
Instead, as in the first embodiment, the value of the random number counter 13b is
"0" is cleared (S51), and then the counter IC 14
Is read (S52). And lead
The counted value is stored in an initial value setting memory 13e of the RAM 13.
(S53), the initial value setting memory 13e
Is less than or equal to “630”, that is,
It is determined whether the value is within the update range of the data 13b (S5).
5). In the process of S54, the initial value setting memory
13e is "630" or less (S54: Ye
s) is a value within the update range of the random number counter 13b. Yo
Therefore, in such a case, similar to the first embodiment, initial values are set.
The value of the constant memory 13e is stored in the random number counter 13b and the current initial value.
Writing to the memory 13c (S56, S57),
The initial value of the update is stored in the counter 13b and the current initial value memory 13c.
Set. On the other hand, in the process of S54, an initial value is set.
If the value of the memory 13e is “631” or more (S54:
No), the value exceeds the update range value of the random number counter 13b
Therefore, the value of this initial value setting memory 13e is
Cannot be set to the initial value of the data 13b. Therefore,
In this case, the value of the initial value setting memory 13e is added.
Update range of the random number counter 13b generated by
The value in the box is set as the initial value for updating the random number counter 13b.
You. Specifically, first, the value of the initial value setting memory 13b is
"630", that is, the value of the update range of the random number counter 13b
Is divided by the upper limit value (maximum value) (S85), and the division is performed.
The remainder value obtained as a result of the
Write to the value memory 13c (S86, S87),
Counter 13b and the initial value of the update in the current initial value memory 13c.
Set. The remainder is stored in the initial value setting memory 13e.
With the upper limit value “630” of the update range of the random number counter 13b.
Since the division is performed, the value within the update range of the random number counter 13 is
It becomes. Note that the random number counter 13b uses this S
56 or the value set by the processing of S86
As the period value, a random number update process (S16, see FIGS. 4 and 7)
) Starts the update in the first cycle. As described above, the value obtained from the counter IC 4 is
Is divided by a predetermined value, and the remainder is
3b by setting the initial value of the update of 3b
Similarly, the initial value of the update of the random number counter 13b is
It can be changed at random. Therefore,
The value of the random number counter 13b is appropriate due to poor backup etc.
Is not held, or the clear switch 30c is pressed.
When the value of the random number counter 13b is cleared by the following,
The random number counter 13b is generated at random.
Since the update is started from the initial value, the random number counter 1
When the initial value of the update of 3b becomes a fixed value such as "0"
To prevent the randomness of the random number counter 13b from decreasing.
You can do it. In each of the embodiments described above, claim 1

However, those which oscillate pulses at high speed are suitable.
You. Such “high speed” means that the oscillation means (count clock
14a, 104a) are transmitted to the MPU 11
At least the frequency of the operation clock 11a that outputs
It is to the same extent. Therefore, the count
