Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and a game machine for improving security between a game control board and a peripheral board in a game machine, and more particularly to a system in which a hanging device is provided between the game control board and the peripheral board. The present invention relates to a gaming machine security system and a gaming machine suitable for preventing a peripheral board from malfunctioning even if attached.

[0002]

2. Description of the Related Art Conventionally, in gaming machines such as pachinko machines,
As a technology for improving the security of a game control board for controlling a gaming state of a gaming machine, for example, Japanese Patent Application Laid-Open No. H11-276699
There was a gaming machine disclosed in the official gazette. This gaming machine prevents the ROM mounted on the game control board from being replaced with an unauthorized ROM, and is specifically configured as follows. The game control program written in the ROM mounted on the game control board includes a security check code generation routine. The security check code generation routine generates a security check code by loading the value of the program counter and adding the value to the previous load value. The security check code is sent to the symbol display control board. The display control CPU mounted on the symbol display control board checks whether the security check code is a normal value,
If not, stop the operation.

[0003] Thus, when an unauthorized ROM is mounted, the variable display of the gaming machine is stopped. As a result, illegal R
Even if it is replaced with OM, it becomes impossible to play a game, so that replacement with unauthorized ROM can be prevented after all. In addition, by stopping the operation of the circuit side of the peripheral board,
The replacement with the unauthorized ROM can be immediately recognized from outside the gaming machine.

[0004]

As described above, the regular R
Replacing an OM with a fraudulent ROM is one of the fraudulent acts. However, fraudulent acts are not limited to these. For example, other fraudulent acts include malfunctioning a gaming machine by radio waves or special There is something that attaches a special device. Of these, in particular, so-called hanging devices used for fraudulent installation of special devices in the middle of wiring are difficult to find due to downsizing of the devices, etc., and are easy to mount compared to fraudulent ROMs. Is one of those things.

[0005] One of the typical hanging devices is a wiring for connecting a starting winning port switch for detecting that a game ball has won the starting winning port and a game control board for controlling a game state of the gaming machine. Some of them are mounted on the way, and this is to electrically delay the detection signal from the starting winning opening switch so that the game control device causes a special prize state. This is attached between the start winning opening switch and the game control board, but it is assumed that a dangling device attached between the game control board and the peripheral board will appear in the future. For example, if the prize ball payout control board is taken as an example of the peripheral board, it is a hanging device attached in the middle of the wiring connecting the game control board and the prize ball payout control board, regardless of the payout control of the game control board , So that the award ball payout control board pays out the award ball,
One that outputs false payout information to the winning ball payout control board may be considered.

However, in the above-mentioned conventional gaming machine, the security check code from the peripheral board side is held correctly, and the security check code from the game control board and the held security check code match. Because of the configuration that determines whether or not
In a state where the OM is attached, the security check code is transmitted and received as a fixed value between the game control board and the peripheral board, so that there is a high possibility that the correct security check code is known to the outside. Therefore, once the correct security check code is known, a dangling device that outputs the same security check code may be easily created. Illegal R
From the perspective of preventing it from being replaced by OM,
Indeed, it is relatively effective to complicate the security check code calculation process, but for a dangling device, no matter how complicated the security check code calculation process is, the output security check code is As long as the value is fixed, fraudulent acts can be easily performed.

Therefore, the present invention has been made in view of such unresolved problems of the prior art, and even if a hanging device is mounted between a game control board and a peripheral board, It is an object of the present invention to provide a gaming machine security system and a gaming machine suitable for preventing a peripheral board from malfunctioning.

[0008]

According to a first aspect of the present invention, there is provided a security system for a gaming machine, comprising: a gaming control board for controlling a gaming state of the gaming machine; And a peripheral board that operates based on control information from the game control board, the game control board has first security information generating means for generating security information whose contents dynamically change based on a predetermined rule. The security information and the control information generated by the first security information generation means are transmitted to the peripheral board, and the peripheral board includes:
A second security information generating unit that generates the security information based on the predetermined rule, wherein the security information generated by the second security information generating unit and the security information from the game control board have a predetermined relationship. If not, operation based on control information from the game control board is prohibited.

With this configuration, in the game control board, the first security information generating means generates security information based on a predetermined rule. Then, the generated security information and control information are transmitted to the peripheral board. On the peripheral board, the second security information generating means generates security information based on the same predetermined rule as that of the first security information generating means.
When receiving the security information and the control information, if the generated security information and the received security information do not satisfy the predetermined relationship, the operation based on the received control information is prohibited.

Here, the first security information generating means may have any configuration as long as it generates security information whose contents change dynamically. For example, security information whose contents dynamically change every time communication is performed with the peripheral board may be generated. However, from the viewpoint of improving security, every time communication with the peripheral board is performed, It is preferable to generate security information whose contents dynamically change. This is the same for the second security information generating means.

Further, the first security information generating means may have any configuration as long as it generates security information based on a predetermined rule. For example, security information may be generated based on a value calculated by a predetermined function, security information may be generated based on a random number table, Security information may be generated based on control information or control information that has been transmitted in the past. On the other hand, the second security information generating means, based on the same predetermined rule as the first security information generating means, that is, in the case of the above example, the predetermined function and the random number used in the first security information generating means Security information is generated based on the same information as a table or control information.

Further, the second security information generating means may generate the security information at any time. For example, security information may be generated at the timing of receiving security information and control information, or security information may be generated while waiting for reception of security information and control information. Is also good. This is the first
The same applies to the security information generating means.

In order to satisfy the predetermined relationship, for example, the security information to be verified matches the security information to be verified, and an operation is performed by a predetermined operation formula using the security information to be verified. That the result matches the security information of the object to be verified, or that the result of performing the operation using the security information of the object to be verified using the predetermined arithmetic expression and the security information of the object to be verified is used to perform the operation using the predetermined arithmetic expression The results are the same.

As the peripheral board, if the gaming machine is a pachinko machine, for example, a prize ball payout control board, a rental ball payout control board, an indicator light control board, a voice control board, a symbol display control board, or a launch control board. Is mentioned. Of these, it is particularly preferable to apply the present invention to a winning ball payout control board and a rental ball payout control board. This is because the malfunctions of these substrates cause significant fluctuations in profits and disadvantages, and there is a high possibility that a hanging device can be attached.

Further, according to a second aspect of the present invention, in the security system for a gaming machine according to the first aspect, the first security information generating means includes a past security board with respect to the peripheral board. The security information is generated based on control information that has been transmitted to the game control board, and the second security information generation unit is configured to generate the security information based on control information that has been received from the game control board in the past. The security information is generated.

With this configuration, in the game control board, the first security information generating means generates security information based on control information that has been transmitted to the peripheral board in the past. In the peripheral board, the second security information generating means generates security information based on control information that has been received from the game control board in the past.

Further, according to a third aspect of the present invention, there is provided a game machine security system according to any one of the first and second aspects.
The peripheral board is a game medium payout board for paying out game media, the control information is payout information indicating the number of game media to be paid out, and the first security information generating means includes a game medium payout board. The payout information transmitted before the first predetermined number of the payout information that has been transmitted to the substrate in the past is added to the payout information transmitted before the second predetermined number of times different from the first predetermined number of times. Is generated as the security information, and the second security information generating means receives the payout information which has been received in the past from the game control board before the first predetermined number of times. The security information is generated by adding the payout information thus obtained and the payout information received the second predetermined number of times before.

[0018] With this configuration, the game control board is configured such that the payout information transmitted before the first predetermined number of times among the payout information transmitted in the past to the game medium payout board and the second predetermined number of times. The sum of the payout information transmitted a number of times before is generated as security information. In the peripheral board, the second security information generating means causes the first security information generating means to output the first payout information among the payout information received in the past from the game control board.
The sum of the payout information received a predetermined number of times ago and the payout information received a second predetermined number of times ago is generated as security information.

Here, the first security information generation means generates, as security information, at least the sum of the payout information transmitted before the first predetermined number of times and the payout information transmitted before the second predetermined number of times. In addition, the security information is generated by adding the payout information transmitted before the third predetermined number of times different from the first predetermined number of times and the second predetermined number of times. May be. This is the same for the second security information generating means.

[0020] On the other hand, in order to achieve the above object, the gaming machine according to claim 4 of the present invention performs a lottery to determine whether or not a predetermined gaming state is caused by a predetermined event, and a result of the lottery. A game machine for providing a predetermined game value to a player when it is determined that the predetermined game state is caused, the game system having the security system for a game machine according to any one of claims 1 to 3.

With this configuration, in the game control board, the first security information generating means generates security information based on a predetermined rule. Then, the generated security information and control information are transmitted to the peripheral board. On the peripheral board, the second security information generating means generates security information based on the same predetermined rule as that of the first security information generating means.
When receiving the security information and the control information, if the generated security information and the received security information do not satisfy the predetermined relationship, the operation based on the received control information is prohibited.

Here, the predetermined game state may be any state. If the gaming machine is a pachinko machine, for example, a special prize state that is a gaming state advantageous to the player, and a probability variation state that is a gaming state in which the special prize state easily occurs. Also, if the gaming machine is a pachislot machine,
For example, a regular bonus (hereinafter, simply referred to as “regular”), which is a gaming state advantageous to the player, and a big bonus (hereinafter, simply, “big”), which is a gaming state more advantageous to the player.

When the number of game balls supplied to 7 is insufficient, a stop signal for stopping the firing device 161 is output to the firing control board 160 to secure a predetermined number of prize balls.

The CPU 220 is composed of a microprocessing unit MPU and the like, and receives a predetermined operation clock (for example,
4 [ms]), and operates based on a game control program capable of executing one cycle.
The game control program stored in the predetermined area of 0 is activated, and the prize ball payout control processing shown in the flowchart of FIG. 3 is executed. FIG. 3 is a flowchart showing the prize ball payout control process.

The prize ball payout control processing is such that, when a game ball wins in the starting winning port 105 and other various winning ports 112 to 115, the prize ball payout is performed so as to pay out the number of game balls corresponding to the winning port. This is a process for controlling the control board 156. When the process is executed by the CPU 220, the process first proceeds to step S100 as shown in FIG.

In step S100, the value of a variable mode for storing a security check code whose contents dynamically change every time communication is performed with the prize ball payout control board 156 is set to "0". Transition. In step S102, a detection signal from the starting winning opening switch 131 or various winning opening switches 132 is transmitted to the I / O 25
By reading from a predetermined port corresponding to the starting winning opening switch 131 or various winning opening switches 132 among the input ports of 0, it is determined whether or not a detection signal is input from the starting winning opening switch 131 or various winning opening switches 132. When it is determined that a detection signal has been input (Ye
In step s), the process proceeds to step S104. If not (No), the process waits in step S102 until a detection signal is input.

In step S104, the number of winning balls corresponding to the winning opening to which the detection signal has been input is set as a variable event for storing the number of game balls to be paid out. The number of prize balls corresponding to the winning opening is determined, for example, with reference to a prize ball number table. In the prize ball number table, the number of prize balls to be paid out is associated with each of the starting prize port 105 and other various prize ports 112 to 115.

Then, the flow shifts to step S106, in which the value of the variable mode is set as a mode command and the winning ball payout control board 15 is set.
6 and the process proceeds to step S108 where the variable event
Is transmitted to the prize ball payout control board 156 as an event command, the process proceeds to step S110, a process of updating the value of the variable mode is executed, and the process proceeds to step S102.

Next, the process of updating the variable mode in step S110 will be described in detail with reference to FIG. FIG.
9 is a flowchart showing a process for updating a variable mode.
The process of updating the variable mode is a process of updating the value of the variable mode in order to dynamically change the content of the security check code every time communication is performed with the award ball payout control board 156. Upon execution, as shown in FIG. 4, the process first proceeds to step S200.

In step S200, a value obtained by adding the value of the variable event to the value of the variable mode is set as a new value of the variable mode, and the flow advances to step S202 to set the value of the variable mode to "128" (hexadecimal). “080h”) or more, and when it is determined that the value of the variable mode is “080h” or more (Yes), the process proceeds to step S204, and the value of the variable mode is changed to “127”. (Hexadecimal "07F
h ") is subtracted, and a series of processing is completed to return to the original processing.

On the other hand, if it is determined in step S202 that the value of the variable mode is less than "080h" (No), a series of processing is terminated and the processing returns to the original processing. Next, the configuration of the winning ball payout control board 156 will be described in detail. Although not shown, the prize ball payout control board 156 has a CPU, a ROM, and a RAM connected by a bus, similarly to the main board 200.
The CPU activates a game control program stored in a predetermined area of the ROM, and executes a prize ball payout process shown in the flowchart of FIG. FIG. 5 is a flowchart showing the prize ball payout process.

The prize ball payout processing is performed by the even board from the main board 200.
This is a process of paying out the game balls of the number of prize balls indicated by the t command, and when the CPU executes the process, the process first proceeds to step S300 as shown in FIG. In step S300, the value of the variable mode is set to “0”, and the process proceeds to step S302 to determine whether a mode command has been received. When it is determined that the mode command has been received (Yes), The process proceeds to step S304,
If not (No), the process waits in step S302 until a mode command is received.

In step S304, it is determined whether or not the received mode command matches the value of the variable mode.
When it is determined that the received mode command and the value of the variable mode match (Yes), the process proceeds to step S306 to determine whether an event command has been received, and that the event command has been received. If it is determined (Yes), the process proceeds to step S308, but if not (N
o) is a step S306 until the event command is received.
Wait at.

In step S308, the prize ball payout device 157 is controlled so as to pay out the game balls having the number of prize balls indicated by the event command.
A process for updating the value of de is executed, and the process proceeds to step S302. On the other hand, when it is determined in step S304 that the received mode command does not match the value of the variable mode (N
In step o), the process proceeds to step S312 to execute a predetermined error process (for example, a process of stopping the operation of the winning ball payout control board 156), and ends a series of processes.

Next, the process of updating the variable mode in step S310 will be described in detail with reference to FIG. FIG.
9 is a flowchart showing a process for updating a variable mode.
The process of updating the variable mode is a process of updating the value of the variable mode in order to dynamically change the content of the security check code every time communication is performed with the award ball payout control board 156. Upon execution, as shown in FIG. 6, the process first proceeds to step S400.

In step S400, a value obtained by adding the value of the variable event to the value of the variable mode is set as a new value of the variable mode, and the flow advances to step S402 to set the value of the variable mode to "128" (hexadecimal). “080h”) or more, and when it is determined that the value of the variable mode is “080h” or more (Yes), the process proceeds to step S404, and the value of the variable mode is changed to “127”. (Hexadecimal "07F
h ") is subtracted, and a series of processing is completed to return to the original processing.

On the other hand, if it is determined in step S402 that the value of the variable mode is less than "080h" (No), a series of processing is terminated and the processing returns to the original processing. Next, the operation of the above embodiment will be described. First, when the power of the pachinko machine is turned on, the game control program is read from the ROM 230 by the CPU 220 on the main board 200, and the game control process is executed at a predetermined cycle according to the game control program. In the prize ball payout control process (FIG. 3) which is a part of the game control process, the variable mo
“0” is set to the value of de as an initial value.

In such a state, when a game is started by the player and, for example, a game ball wins in the start winning opening 111, a detection signal is output by the start winning opening switch 131. When the detection signal is output, the CPU 220
After step S104, the number of winning balls corresponding to the starting winning opening 111 is set in the variable event. At this time, assuming that the number of winning balls corresponding to the starting winning opening 111 is, for example, “5”, the value “0” of the variable mode is set as a mode command through the steps S106 and S108, and the winning ball payout control board 156.
Is transmitted to the winning ball payout control board 156 as an event command.

When the transmission of the mode command and the event command is completed, the value “5” obtained by adding the value “5” of the variable “event” to the value “0” of the variable “mode” through steps S200 to S204 becomes the new value of the variable “mode”. Is set as On the other hand, when the power is turned on to the pachinko machine, the CPU reads the prize ball payout control program from the ROM in the prize ball payout control board 156, and executes the prize ball payout process (FIG. 5) according to the prize ball payout control program. It is executed at a predetermined cycle. In the winning ball payout process, “0” is set as an initial value for the value of the variable mode after step S300.

In this state, when the mode command “0” transmitted by the prize ball payout control processing is received, the received mode command “0” matches the value “0” of the variable mode. Through S306, the event command “5” is received, and the prize ball payout device 157 is controlled so as to pay out the game balls of the number of prize balls indicated by the received event command “5”. As a result, the prize ball payout device 157
Thereby, five game balls are paid out.

When the control of the prize ball payout device 157 is completed,
Through steps S400 to S404, the value "5" obtained by adding the value "5" of the variable event to the value "0" of the variable mode is set as a new value of the variable mode. That is, the award ball payout control board 156 holds the same security check code as the value of the variable mode, which is the same as the security check code transmitted next by the main board 200.

As described above, in the main board 200, the mode command “0” is generated as a security check code in the initial state, and when paying out five game balls, the mode command “0” and the event command “5”
Is output to the winning ball payout control board 156. On the other hand, in the award ball payout control board 156, in the initial state, a mode command “0” is generated as a security check code. Therefore, the main board 200 and the prize ball payout control board 15
When the hanging device is not attached between the main board 200 and the security check code generated by the prize ball payout control board 156, the main board 200 is instructed. The number of game media paid out is paid out.

Next, in the state where five game balls have been paid out from the initial state as in the above example, for example, if 15 prize balls are paid out, in the main board 200, the variable
The mode value “5” is transmitted as a mode command, and the variable event value “15” is transmitted as an event command.
When the transmission of these commands is completed, the value “2” obtained by adding the value “15” of the variable event to the value “5” of the variable mode
"0" is set as the new value of the variable mode.

When the mode command “5” is received by the winning ball payout control board 156, the event command “15” is received because the received mode command “5” matches the value “5” of the variable mode. Then, by the prize ball payout device 157, 1
Five game balls are paid out. When the control of the prize ball payout device 157 is completed, “20” obtained by adding the value “15” of the variable event to the value “5” of the variable mode is set as a new value of the variable mode.

Next, as shown in the above example, 5 minutes from the initial state.
In a state where 15 and 15 game balls have been paid out, for example, if 10 prize balls are paid out, the main board 200
Then, the value “20” of the variable mode is transmitted as a mode command, and the value “10” of the variable event is transmitted as an event command. When transmission of those commands ends, the variable mo
The value "30" obtained by adding the value "10" of the variable event to the value "20" of de is set as a new value of the variable mode.

When receiving the mode command “20”, the winning ball payout control board 156 receives the mode command “2”.
Since the value “0” matches the value “20” of the variable mode, ev
Upon receiving the ent command “10”, the award ball payout device 157 pays out ten game balls. Prize ball payout device 1
When the control of step 57 is completed, the value of the variable "mode" is changed to "20".
The value "30" obtained by adding the value "10" of the event is the variable mode
Is set as the new value of

As described above, the content of the security check code changes every time communication is performed with the prize ball payout control board 156 based on the event command transmitted to the prize ball payout control board 156 in the past. Change.
In the above example, the security check code is
It changes to “0”, “5”, and “20”. In addition, for example,
Even if a dangling device that outputs only the event command is attached, the winning ball is not paid out on the winning ball payout control board 156 because the mode command does not match.

As described above, in the present embodiment, the main board 200 generates a security check code whose contents dynamically change, and sends the generated security check code and event command to the winning ball payout control board 156. The award ball payout control board 156 is transmitted to the main board 2
00, a security check code identical to the security check code generated in step S00 is generated. If the generated security check code does not match the security check code from the main board 200,
Operation based on the event command is now prohibited.

As a result, the correct security check code becomes difficult to understand, and it is relatively difficult to create a dangling device that outputs the same security check code to the outside as the correct security check code. Therefore, even if a hanging device is attached between the main board 200 and the prize ball payout control board 156, malfunction of the prize ball payout control board 156 can be prevented to some extent as compared with the related art.

Further, in the present embodiment, the main substrate 200
