In the normal game state (normal probability state), the counter value is "7" to generate a special prize state, and otherwise, the special prize state is not generated. In the high probability state, the counter values “7”, “39”, “1”
A special prize state is generated at "39", and otherwise, no special prize state is generated. Thus, the total count value is changed to "24
If it is set to "0", the special prize state can be generated with a probability of 1/240 in the normal gaming state, and the special prize state can be generated with a probability of 1/80 in the high probability state.

The reach selection random number counter 402 is a counter used to select a variation pattern of a special symbol. When this counter value is randomly selected, a symbol variation pattern corresponding to the selected counter value is selected. The big hit symbol selection random number counter 403 is used to select a special symbol used when the same symbol is stopped and displayed in the display area of the special symbol display device 104 so that, for example, three are aligned in a horizontal line when the big hit state occurs. A counter,
When this counter value is selected by lot, each display section of the special symbol display device 104 is displayed in a symbol pattern corresponding to the selected counter value.

When the counter value is "0", "1", "2",

A "common process 1" including an output buffer clearing process for clearing the output buffer and various timer processes for updating timer values of various timers (not shown) used for gaming machine operation control is executed.

Next, in step S112, it is checked whether or not each of the switches 204, 205, 206, 207, etc. is disconnected or short-circuited. If it is determined that any of these faults has occurred (Yes), the process proceeds to step S112. The flow shifts to S116, executes an error process for storing an error flag in a predetermined area of the RAM 202 and performs control or the like necessary for notifying that it is in an abnormal state, and shifts to S126. If it is determined that has not occurred (No), the process proceeds to step S118 (step S114).

Next, in step S118, a special symbol start switch 204, a normal symbol operation switch 205,
Big winning opening switch 206, ordinary electric accessory switch 207

The stored random number is stored in a predetermined area 202, and a hit determination, a symbol determination, and the like are performed with reference to the stored random value.

Specifically, the special symbol start switch 204
Or, when the ordinary design electric accessory switch 207 outputs a winning ball detection signal, the table area 2 described above is used.
15, it is determined whether or not the extracted random number value (the random number counter 701 for judging a prize state) causes a big hit, and the random number counter 403 for selecting a big hit state symbol and the non-matching symbol selection are determined. Random number counter 404-
Processing such as determination of a special symbol to be displayed is performed by referring to the information stored in the table area 406 and the table area 215, and necessary control data is stored in a predetermined position of the output buffer.

When the normal symbol operation switch 205 outputs a detection signal, the small hit is determined by referring to a random number generated by a random number counter (not shown) and a predetermined small hit value stored in the ROM 201. In addition to deciding whether or not to cause a state, a normal symbol to be displayed is determined, and necessary control data is stored in a predetermined area of the output buffer.

Next, in step S120, symbol display control such as symbol change and stop is performed on the special symbol display device 104 and the ordinary symbol display device 107, and in step S11.
The control data necessary for performing the control for displaying the symbol selected in step 8 and the control for displaying the animation image during the big hit period is stored in a predetermined area of the output buffer. Since this specific control is a main part of the present invention, it will be described later.

Next, in step S122, during the big hit state or the small hit state, the special winning opening 109
And control data for controlling the opening and closing of the ordinary electric accessory 110 in a predetermined opening pattern is stored in a predetermined area of an output buffer. The various control data stored in the output buffer as described above is transmitted to the corresponding device by the port output process in step S110, and the device that has received the control data performs operation control based on the received control data.

And an LCD module 540 as an output device.

The main control unit 200 and the display control CP
PLD (Programmable Logical) between U500
Device: programmable logic device) 560 is provided. Also, the display control CPU 500 and the LC 500
A PLD 530 is also provided between the DLD 540 and the PLD 530, and a voltage level tolerance gate 535 for stabilizing an output voltage is formed in the PLD 530. Therefore, a voltage level tolerant gate 535 for stabilizing the output voltage is provided between the display control CPU 500 (sub-control unit) and the LCD module 540 (output device).
The supply voltage to 0 is stabilized, and the occurrence of a display error is suppressed. The voltage level tolerance gate 535 supplies the output voltage stably even if the input voltage fluctuates, and can be realized using, for example, a switching regulator or various logic gates.

The PLD 560 includes a voltage level tolerant gate 562 for stabilizing the voltage, a command normality judging unit 566, and a switch 566. Further, the LED 570 is connected to the command normality determination unit 566, and the button 571 is connected to the switch 56.
6 is connected.

(Operation) First, a button 571 is operated so that a control command is given to the command normality judging section 564. The voltage of the control command transmitted from the main control unit 200 is stabilized through the voltage level tolerant gate 562, so that a communication error is suppressed.

Next, the command normality determining unit 564
It is checked whether the received control command has been transmitted at the timing shown in FIG. If the command is transmitted at the timing shown in FIG.
Send to After that, the display control CPU 500 receives these control commands from the command receiving unit 550 and performs corresponding display control.

On the other hand, the command normality judging section 564 checks whether or not the received control command has been transmitted at the timing shown in FIG. 10 first, and the command is transmitted at the timing shown in FIG. If not, the LED 570 is turned on because it is not normal. Accordingly, when the command normality determining unit 564 determines that the control command is not normal, the fact is notified by lighting the LED 570, so that it is easy to grasp that a communication error in which the control command is not normal has occurred. Can be.

As described above, the voltage level tolerant gate 5 is provided between the main control unit 200 and the display control CPU 500.
62 is provided to stabilize the output voltage, stabilize the voltage level of the control command to suppress the occurrence of a communication error, and if a communication error occurs, the command normality determination means 564 sets this gate to Since the normality of the control command sent via the PC is determined, occurrence of a communication error can be grasped.

Next, the control command is directly given to the command receiving section 550 by operating the button 571. Then, display control CPU 500 receives these control commands from command receiving section 550 and performs corresponding display control.

It would be extremely difficult to apply the work to the surface. The reason for this is that, unlike software, in a PLD, each functional unit is realized by hardware consisting of a large number of gate groups.

Since the voltage level gate 535 on the output device side is formed on another PLD 530, the voltage level gate 535 formed on the other PLD 530 is formed.
It is also extremely difficult to analyze the mechanism of the game and to make a trick so as to play a fraudulent game.

70, the address decoder 520, the gate 580, etc. are all realized by hardware and formed on a PLD (programmable logic device), so that the contents of the logic gate cells, the operation of the comparing means, and the inconsistency processing unit 57
Since it is difficult to analyze the operation of the address decoder 520b, the operation of the address decoder 520b, and the like, it is extremely difficult to perform the work for making the change of the game program undetectable.

In the above description, the special symbol display device 104 has been described as an example of the peripheral device. However, other peripheral devices are also basically a CPU (sub-control unit) and a ROM.
, A RAM, and an output device (for example, an LED for a lamp display device), so that the present invention can be similarly applied.

Although the embodiments of the present invention have been described above, various modifications and changes can be made to each of the above embodiments without departing from the spirit of the present invention. For example, a voltage level tolerant gate may be arranged in another part in the special symbol display device 104. In the above embodiments, a pachinko machine has been described as an example of a gaming machine, but the present invention can be applied to other gaming machines such as pachislot machines and TV games.

As described above, according to the present invention, a voltage stabilizing means is provided between the main control means and the sub-control means to stabilize the output voltage and reduce the voltage level of the control command. In addition to stabilizing the occurrence of communication errors, even if a communication error occurs, the command normality determination means determines the normality of the control command sent through this gate.
