The above-mentioned electrical control device (feature product control circuit 2
The control in 8) will be described based on the flowcharts shown in FIGS. When the electric control device (feature product control circuit 28) is activated, first, the electric control device (feature product control circuit 28) performs input processing of necessary information. Then, it is determined whether or not the power is on, and if the power is on, initialization processing of each setting value is performed, and setting value reading processing for reading the probability setting value is performed to reset the device. wait.

On the other hand, when the power is not turned on, a setting process for setting a probability is performed, an output process for outputting a signal to a peripheral device is performed, and the selected probability is calculated based on the probability set by the probability setting. Select a random number table to generate. In this embodiment, there are three groups of random numbers, and the respective probability values are different.

Here, it is judged whether or not a fraud has occurred, and if the fraud has not occurred, a time division branch process for performing an interrupt process is performed.

In the interrupt processing, special figure game processing, symbol variation processing, symbol editing processing, and decoration editing processing are performed.

In the special figure game process, the process of storing the number of winning balls in the first type starting opening 19, the process of determining whether or not the extracted random number value is a hit, the process of determining a stop symbol based on the result of the determination, the big hit A probability variation process that makes the probability of occurrence of a high probability a high probability, a big hit operation process that controls opening and closing of the special winning opening 20, and the like are performed.

The probability variation process for increasing the probability of the above-mentioned big hit to be a high probability will be described in more detail. In the present embodiment, as will be described in detail later, the probability that the stop symbol is a hit uses three types of probabilities, but in each probability, for example, the stop symbol is “7”, “7”, “7”, "3"
In the case of "3", "3", "1", "1", and "1", a big hit is configured. Therefore, among the stop symbols for this hit, for example, in the case of the stop symbols of "7", "7", and "7", after the jackpot state is over, the game state is further advantageous to the player. It changes the probability of the next big hit. For example, the normal probability is 1/20
When it is 0, it is changed to 1/20, when it is 1/210, it is changed to 1/21, and when it is 1/220, it is changed to 1/22. Then, after the big hit occurs at the above-mentioned probability that the more advantageous big hit occurs than usual, the probability is returned to the normal big hit probability.

In the symbol variation process, the special symbol display device 18
The variation process of the special symbol displayed on is performed. In the symbol editing process, the output data of the special symbol displayed on the special symbol display device 18 is edited. In the decoration editing process, lamp, L
Decorative processing such as ED is performed.

When the interruption process is completed, the special winning opening 20
The count switch prize monitoring processing for counting the number of winning prizes to the first prize starting opening 19 is performed, and the continuous switch winning prize monitoring processing for counting the number of prize winnings to the continuous winning prize opening in the special winning opening 20 is performed. However, a predetermined fixed number, for example, 4
While storing the number of winning prizes up to the number, the special symbol switch monitoring process for controlling the taking in of the random number value for determining the display symbol on the special symbol display device 18 is performed.

If the count switch 21 does not count one winning ball when the special winning opening 20 is opened,
Performs fraud monitoring processing to monitor fraud such as short-circuiting or opening of a predetermined switch. In the above-described fraud determination processing, when it is determined that the fraud is illegal, the fraud monitoring processing is performed by skipping each of the above-mentioned processing. In this fraud monitoring process, only the side lamps 25 are flashed at high speed in order to inform the gaming shop staff of the fraudulent state.
All other illumination members, such as lamps and LEDs, are turned off, and the speaker 50 emits an illegitimate warning sound for notifying an illegitimate state.

After that, the sound generated from the speaker 50 is edited and output, the presence or absence of the safe sphere is monitored, and the prize sphere control process of transmitting the prize sphere number data to the discharge control circuit 29 is performed, and the device is reset. Wait for you.

The above-mentioned set value reading process will be described in more detail with reference to the flowchart of FIG. In the set value reading process, it is first determined whether or not the probability setting display switch 35 is turned on when the power is turned on.

When the operating portion 37 of the switch member 36 is rotated counterclockwise and the power is turned on with the probability setting display switch 35 turned on, an incorrect flag is set and a probability setting write flag is set. Set and set the 5 sec timer. The illegal flag is set here
This is because during the probability setting, an illegal processing state, that is, an illegal display is performed so that the game cannot be performed.

On the other hand, when the switch member 36 is turned off and the power is turned on, the probability storing means EEPRO is used.
The probability setting value stored in M46 is read. The probability setting value in this case does not store the probability value to be set as it is, but the identification number of the probability, for example, the identification number "1" when the probability is 1/200, and the identification number when it is 1/210. In the case of the identification number "2" and 1/220, the identification number "3" is stored.

Then, it is judged whether or not the probability setting value is normal, that is, whether the probability setting value is a number other than the above-mentioned identification number, for example, "4" or the like, and it is judged that the probability setting value is a normal probability setting value. , The number (identification number) of the random number setting table corresponding to the probability setting value is set.

On the other hand, if the probability setting value is abnormal,
The number in the random number setting table is set as "2". Here, it is determined that the probability setting value is abnormal, when the factory is shipped without writing anything in the EEPROM 46, even if no setting is made in the game shop,
This is because the number in the random number setting table is set to "2" for the time being. Then, the probability setting display data is set on the probability setting value display 40, and the current setting value is displayed.

The above setting process will be described in more detail with reference to the flowchart of FIG. In the setting process, first, the state of the probability setting write flag is determined, and if the probability setting write flag is set, a setting device operation signal is transmitted to the management device installed in the management room or the like in the game store, and the game is played. The management apparatus is made to recognize that the probability is being set in the machine 1.

Then, the state of the probability setting switch 34 is judged, and when the operation portion 37 of the switch member 36 is turned clockwise to turn on the probability setting switch 34, the number of the random number setting table is updated to set the probability setting. Set the display data to the probability setting indicator 40 and display the current set value.
Set the sec timer. Here, when the probability setting switch 34 is turned on again while the 5 sec timer is operating, the random number setting table is updated to the table of the next number,
The current set value is displayed and the 5 sec timer is set again. That is, the number of the random number table set each time the operation portion 37 of the switch member 36 is rotated clockwise and the probability setting switch 34 is turned on is "1"-"2"-.
It changes cyclically like "3"-"1".

On the other hand, when the probability setting switch 34 is not turned on, that is, the operation portion 37 of the switch member 36 is in the neutral state for 5 seconds or more, and the 5 sec timer times out, the probability setting write flag is cleared,
The transmission of the setting device operation signal to the management device is stopped, and the management device is made to recognize that the probability setting in the gaming machine 1 is completed.

Then, the set probability setting value, eg, "1" is written in the EEPROM 46, clear data is transmitted to the probability setting value display 40, and the probability setting value display 40 is displayed.
Is cleared and the injustice flag is cleared so that the game which is impossible during the probability setting is made possible.

On the other hand, if the probability setting write flag is not set at the beginning of the process, the state of the probability setting display switch 35 is judged. Here, when the operation portion 37 of the switch member 36 is rotated counterclockwise and the probability setting display switch 35 is turned on, the probability setting display data is set in the probability setting value display 40 to set the probability setting value. The present set probability value is displayed on the display 40.

On the other hand, when the probability setting display switch 35 is off, clear data is set in the probability setting value display 40 and the probability setting value display 40 does not display.

In the present embodiment, once the power is turned on, even if the probability setting display switch 35 is operated, the current set probability value is only displayed on the probability setting value indicator 40, Cannot be reset. In order to reset the probability, it is necessary to turn off the power again and then turn on the power with the probability setting display switch 35 turned on as shown in the probability value reading process.

As described above, in this embodiment, when setting and changing the probability, a signal to that effect is output to the management device. Therefore, when the probability change is made illegally, a signal indicating that the probability change has been made illegally is transmitted to the management device, so that it is possible for the gaming shop to recognize that the probability change has been made. it can.

If the probability setting and the probability change are to be executed by disconnecting the connector of the transmission signal line to the management apparatus, the probability setting and the probability change may be controlled so as to be impossible.

Further, in the case of setting the probability and changing the probability, first, a signal for performing the probability setting and the change of the probability is transmitted to the management device, and a signal for permitting the probability setting and the change of the probability is sent from the management device. The probability may be set and the probability may be changed only when received.

The electric control unit is provided with a display section,
When the probability is set or the probability is changed, the operation procedure of the process may be displayed as a message, or a synthetic sound may be generated from the speaker to guide the operation procedure.
