Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine such as a pachinko machine, an arrange ball machine, a sparrow ball game machine, and a rotating body type game machine, and particularly, to start game control despite an abnormal circuit connection. The present invention relates to a gaming machine that does or does not continue.

[0002]

2. Description of the Related Art A ball game machine is generally composed of a plurality of circuit boards separated according to their functions, and the plurality of circuit boards cooperate to realize a complicated and sophisticated game operation as a whole. In such a gaming machine, it is general to include a main control board that is mainly in charge of game control, and a plurality of sub-control boards that operate based on control commands from the main control board.

As the sub-control board, for example, a pattern control board for controlling the liquid crystal display, a payout control board for controlling the payout operation of the game balls, a lamp control board for flashing the game operation by blinking the LED lamps, and the like. There is a voice control board that boosts the game operation. Then, for example, a control command (prize ball command) for instructing payout of 15 balls is transmitted from the main control board to the payout control board by one-way communication.
The payout motor is driven to execute the instruction content from the main control board.

[0004]

However, in the conventional gaming machine, there is a problem that a trouble cannot be prevented in advance because there is no function of checking the connection status between the main control board and the sub control board. For example, if the connection between the main control board and the payout control board becomes defective for some reason, if the game operation is started in that state, the prize balls will not be paid out and the player and the game hall will be disconnected. It may cause troubles.

In consideration of such a situation, instead of transmitting the control command in one direction from the main control board to the sub control board, the sub control board which has received the control command sends a confirmation signal to the main control board. It is also possible to adopt a two-way communication method in which (control command) is returned. With such a configuration, it is possible to reliably detect that the control command is not correctly transmitted, including a case where the cable is not properly connected, and the sub-control board outputs a control command resend command to the main control board. It is also possible.

However, in the case of such a bidirectional communication system, not only the communication control becomes complicated, but also an illegal game may be realized by sending an illegal signal to the main control board. The evil cannot be overlooked. For example, when the payout control board receives the prize ball command, if an illegal act such as illegally issuing a resend command to the main control board is performed, duplicate payout operations are performed.

The present invention has been made in view of the above problems, and an abnormal situation such as a connection failure can be achieved without bidirectional communication of control commands between the main control unit and the sub control unit. An object is to provide a game machine that can be easily detected.

[0008]

In order to solve the above problems, the present invention executes a lottery process for determining whether or not a profit state advantageous to a player is generated, and a game is executed based on the result of the lottery process. A gaming machine comprising: a main control unit that controls operation; and a sub control unit that receives a control command from the main control unit and executes a predetermined game operation based on the received control command. The main control unit is provided with an input unit for inputting the inspection data, while the main control unit is provided with an output unit for outputting fixed inspection data. The connection state with the control unit is grasped.

It should be noted that the present invention may be provided with an informing means so as to inform the player of this when the non-connection state is grasped. Further, external output means may be provided, and when the non-connection state is grasped, this may be output to an external device such as a computer in a game hall.

Furthermore, a stopping means may be provided to stop a predetermined game operation when the non-connection state is grasped. As the predetermined game operation to be stopped, in addition to stopping all operations of the game machine, for example, stop of shooting of a game ball, stop of detection of a predetermined winning state, stop of lottery operation, and the like are applicable. When there are a plurality of sub-control units, the configuration may be such that the connection state of only a specific sub-control unit is grasped,
The configuration may be such that the connection states of all sub-control units are grasped.
In the latter case, at least when the non-connection state of one sub-control unit is grasped, the above-mentioned notification means, stop means,
It is preferable that all or part of the external output means be functional.

In the present invention, it is preferable that the main control unit and the sub-control unit are constructed on different boards, and the sub-control unit is also constructed on a plurality of circuit boards divided by function. Is. The fixed inspection data is typically L level data, but it is preferable that the bit length is 1 bit or a plurality of bits for each sub control unit.

As shown in FIG. 5, various control commands for executing predetermined game operations can be transmitted from the main control board 27 to the sub control boards 28 to 31 by one-way communication. In this way, the main control board 27 does not receive confirmation signals from each sub-control board one by one, so that the control load on the main control board 27 can be reduced, and the transmission control in the main control board and the sub-control board can be reduced. Has become easier. However, the main control board and each sub-control board are connected by inspection lines CON1 to CONN4 for connection confirmation, and the main control board 27 can check the connection state with each sub-control board at any time. ing.

FIG. 6 is a block diagram showing a circuit configuration of the main control board 27. As shown in the figure, the main control board 27 includes a CPU circuit 50 composed of a one-chip microcomputer, a system clock generator 51 for generating a clock signal Φ0 having a frequency that is an integral multiple of the CPU operation clock CLK, and a CPU.
A decode circuit 52 for generating a chip select signal CS for each part based on an address signal from the CPU, an output port circuit 53 for outputting data from the CPU, an input port circuit 54 for the CPU to take in external data, and Output drive circuit 55 that outputs control commands and the like to the control board
And a switch input circuit 56 for inputting ON / OFF states of switches of each part of the game board.

The input port circuit 54, in detail, receives the ON / OFF signals of switches from each part of the game board.
The input port unit 54a and the second input port unit 54b connected to the inspection lines CON1 to CONN4 of the sub control boards 28 to 31 are included. FIG. 7 is a block diagram showing a connection relationship between the main control board 27 and each of the sub control boards 28 to 31, and a specific configuration of the output port circuit 53, the output drive circuit 55, and the second input port section 54b is shown. ing.

The second input port section 54b is specifically
It is composed of an input unit 60 and a data holding unit 59,
The inspection signals from the sub control boards 28 to 31 are received. Data holding unit 5 via input unit 60
The inspection signal (inspection data) supplied to 9 is latched in the data holding unit 59 and transmitted to the CPU at the timing when the chip select signal CS5 is supplied to the data holding unit 59. Although the specific configurations of the input unit 60 and the data holding unit 59 are not particularly limited, in this embodiment, a 74541-equivalent bus buffer is used as the input unit 60 and a 74273-equivalent D buffer is used as the data holding unit 59. Type flip-flop is used.

As shown in FIG. 7, the input unit 60 is connected to the connectors CNia to CN of each sub control board via the connectors CNoa to CNod of the main control board 27 and the connection cable.
connected to id. The corresponding terminals of the connectors CNia to CNid corresponding to the input unit 60 of the main control board 27 are connected to the ground line (L level).
On the other hand, all four input terminals of the input section 60 are fixed to H level by pull-up resistors. Therefore,
The inspection signal in this embodiment has an L level when normal, and has an H level when the main control board and the sub control board are disconnected.

The output port circuit 53 is, in detail, a prize ball port 53a, a voice port 53b, a lamp port 53c,
It is composed of a symbol port 53d and a strobe port 53e, and is a driver 57, 58 (7424 in the embodiment).
5 equivalent bus transceiver) through the main control board 27
Is connected to the CPU data bus.

The prize ball port 53a, the voice port 53b, the lamp port 53c, and the design port 53d correspond to the payout control board 31, the voice control board 30, the lamp control board 29, and the design control board 28, respectively, and output. A control command is output to each sub-control board through the drive circuit 55 (a bus buffer equivalent to 74244 in the embodiment).

The output ports 53a to 53e are specifically configured by D-type flip-flops (74273 or the like in the embodiment), and control commands are synchronized with the chip select signals CS0 to CS4 from the decoder circuit 52. And a strobe signal STB are acquired. The output of the strobe port 53e is the strobe signal STB.
1 to STB4 are supplied to the control boards 28 to 31,
When the strobe signal STBi becomes H level, the CPU of each control board 28-31 is interrupted, and the control command from the main control board 27 is acquired by the interrupt processing program of each control board.

8 to 10 are flowcharts showing a control program of the main control board 27. Main control board 27
Control program is executed after the power is turned on and normally ends in an infinite loop process (ST10) (FIG. 8), a timer interrupt processing program (FIG. 9) that is started every 2 ms, and a power supply voltage is predetermined. N below the value
An NMI processing program (not shown) that is driven by an MI (Non Maskable interrupt) signal to back up the register value of the CPU.

First, the main processing shown in FIG. 8 will be described. When the power is turned on, after the CPU is set to the interrupt disabled state, the CPU registers are initialized (ST
1), the CPU is set to interrupt mode 2 (ST2),
After that, the RAM clear signal is checked (ST
3). The RAM clear signal corresponds to the initialization switch 34, and the power switch 33 is operated while pressing the initialization switch 34 with the front frame 4 of the pachinko machine 1 opened forward as at the start of business. When switched to the on side,
The RAM clear signal is in the ON state.

On the contrary, when the RAM clear signal is OFF, it means that the power is turned on without pressing the initialization switch 34. In this case, it is considered to be the time of restoration from a power failure, so restore the data backed up in the NMI interrupt processing (ST
4) Then, the process before interruption is restarted (ST5).

On the other hand, if the RAM clear signal is ON, after all the game information stored and held in the RAM is erased, the CPU sets the initial symbol to be displayed on the liquid crystal display 14 or this game. After performing initial processing such as setting an interrupt cycle for periodically executing interrupt processing during execution of control, the EI instruction is executed to set itself to the interrupt enabled state (ST6).

Subsequently, the CPU operates the second input port section 54.
The inspection data is acquired from b, and each sub control board 28-3
The connection state with 1 is grasped (ST7). Specifically, first, the chip select signal CS is passed through the decoding circuit 52.
5 is output, and the inspection data of the data holding unit 59 that is latched as a result is acquired. In this embodiment, the inspection data is 4-bit data, which is the same as the number of sub control boards.

Next, the CPU checks whether or not each bit of the inspection data is at a normal level (ST8), and if there is an abnormal level bit, an error for specifying the abnormal sub-control board is detected. After the message is displayed, the process ends (ST9). As described above, it is normal if the 4-bit inspection data is all at the L level, but if any of the inspection data has an H level bit, the connection state with the sub-control board corresponding to the bit. Means abnormal (poor connection or disconnection).

On the other hand, if all the bits of the inspection data are at the normal level, then a random number process (ST10) for the out-of-place symbols that is repeated in an infinite loop is performed. The random number process for the off symbol defines the out symbol pattern drawn on the liquid crystal display 14 when the special symbol lottery is missed in the timer interrupt process.

Next, the timer interrupt executed every 2 msec will be described with reference to the flowchart of FIG.
When a timer interrupt occurs, the contents of each register are saved in the stack area, and switch input management processing, error management processing, etc. are performed (ST20). The switch input management process is a judgment as to whether or not the game ball has passed through the gate or the electric tulip, and the error management process is a judgment as to whether or not an abnormality has occurred inside the device.

Next, the update processing of the hit counter RG and the big hit counter CT related to the normal symbol processing and the special symbol processing is executed (ST21). Although the specific processing content is not particularly limited, it is general to circulate the counter value within a predetermined numerical range, and for example, it is easy to increment each counter value by 1 for each timer interrupt.

When the random number generation process (counter update process) is completed in this way, the value of the process division counter is then determined (ST22), and the corresponding process of ST23 to ST27 is performed. The error management and the switch management described above should be repeatedly performed at short time intervals, but the processing related to the production of a pachinko game is complicated and sophisticated according to the needs of the player, and therefore requires a certain amount of processing time or more. Become. Therefore, in this embodiment, all the game control operations are not completed by one interruption process, but 5
The processing is divided into types of processing, and the divided processings are divided and executed for each interrupt. Therefore, a processing division counter that circulates in the range of 0 to 4 is provided to perform processing according to the value of the processing division counter.

More specifically, when the processing division counter is 0, processing relating to opening of the special winning opening is carried out (ST23), and when the processing division counter is 1, it is in a hit state (opening of the electric tulip). Normal symbol processing including lottery regarding whether or not is performed (ST24), and when the process division counter is 2, special symbol processing including lottery regarding whether or not it is a big hit state is performed (ST25). Further, when the processing division counter is 3, timer management processing related to the opening / closing timing of the electric tulip or the special winning opening is performed (ST26). If the processing division counter is 4,
Information output and error display command creation processing is performed (ST27).

After the processing of any of steps ST23 to ST27 is completed, the value of the processing division counter is updated (ST28), and then the generated command is output to each control board (ST29). Further, the value of each register is restored and is changed to the interrupt enable state, and the interrupt processing routine returns to the main routine (ST29).

FIG. 10A is a flow chart showing the above command output processing (ST29) in detail, and FIG. 10B is a command buffer area (TOP of RAM).
8 bytes from the address). In the command buffer area, timer interrupt processing (ST23
By ST27), necessary control commands are already stored. In the case of this embodiment, there are control commands for the pattern control board, the voice control board, the lamp control board, and the payout control board, but in the initial state, the command buffer area is all cleared to zero. .

Explaining with reference to the flow chart of FIG. 10A, first, inspection data is input from the second input port section 54b (ST40), and whether or not the connection state with all the sub control boards is normal is determined. It is determined (ST41). Then, if there is even one bit indicating an abnormality, error processing such as displaying a message indicating the abnormality is performed as in step ST9 (ST53). In this way, in this embodiment, since the connection state with the sub control board is checked prior to the transmission of the control command, the abnormal state is not overlooked and the game control is not continued.

In the normal case, all the connection states with the sub-control board are normal. In that case, first, it is judged whether or not the control command data exists in the command buffer area (ST42). . If the content of the corresponding area is not zero, it is determined that the control command data exists,
Since the address variable ADR is set to the TOP address in the initial state, it is checked from the contents of the TOP address.
In this embodiment, the control command is 2-byte data excluding 0000H.

When the presence of the command data can be confirmed by the determination in step ST42, the variable LOOP is set in order to output the control command having a 2-byte structure in units of 1 byte.
2 is stored in (ST43). Next, the control command data stored in the command buffer area is output to the corresponding command output port, and the command buffer area storing this control command is cleared to zero (ST44). Specifically, the corresponding chip select signal CSi is output from the decoding circuit 52, and the control command data is written in the corresponding D-type flip-flop 53.

After that, after some time consumption processing is executed (ST45), the STB stored in the RAM area is stored.
Data is output to strobe port 53e (ST46). The initial value of the STB data is 01H, but now, at the timing of outputting the control command to the payout control board 31, the data of 00000001 is output to the strobe port 53e, and only the strobe signal STB1 is set to the H level. Become.

By the processing of step ST46, any one of the strobe signals STB1 to STB4 becomes H level, and the CPU of the corresponding sub control board is interrupted. Therefore, the sub-control board that has received the interrupt inputs a control command in the interrupt processing program.

On the other hand, the main control board 27 consumes a sufficient time to complete the data acquisition processing in the control board which has received the control command (ST47), and then the strobe port 5
Clear data (= 00H) is output to 3e, and all strobe signals STB are set to L level (ST48).

Since the transmission of the control command for 1 byte is completed by the above processing, the variable LOOP is decremented (ST49), and the processing of steps ST42 to ST49 is repeated until the value becomes 0. as a result,
For the control board which should output the control command, ST42
The processing of ST49 is executed twice, and the control command of 2-byte length is continuously output byte by byte.

When the transmission of the control command is completed in this way, the address variable ADR is incremented by +2, the STB data in the RAM area is left shifted, and the processes of steps 42 to ST52 are repeated until the final address of the command buffer. By shifting the STB left, the STB data in the command buffer area is 00000001 → 000.
00010 → 00000100 → 00001000, and unless there is a skip process in step ST42, the process of step ST46 causes strobe data STB1 → STB1 → STB2 → STB2 → STB.
3 → STB3 → STB4 → STB4 are sequentially output.

Although the embodiments of the present invention have been described above, they are merely specific examples and do not particularly limit the present invention. For example, in the embodiment, the main control board and all the sub control boards are connected by the inspection line CONN and the inspection data can be received from all the sub control boards, but a specific sub control board having a high degree of importance (for example, , The payout control board) may be connected by the inspection line.

Further, in the embodiment, the inspection data is 1 bit for each sub-control board, but it is not limited to this. For example, the inspection data may have a 2-bit configuration, and the inspection data may be supplied to both ends of the cable in the connector CNi of the sub control board. In this case,
Even if the connector CNi is attached to one side of the cable but the other side is incompletely attached due to the work of attaching and detaching the connector, the connection failure can be reliably detected.

In the above embodiment, the main control board 27
Was radially connected to all the sub-control boards, but the present invention is not limited to this configuration, and various connection methods including those illustrated in FIG. 11 can be adopted.
That is, the connection relationship between the main control board and the sub control board is appropriately set as long as the configuration detects an abnormal situation such as a connection failure without performing bidirectional communication between the main control section and the sub control section. Can be changed. However, the present invention is not intended to exclude bidirectional communication of control commands, and bidirectional communication as shown in FIG. 11B may be adopted. In FIG. 11, solid arrows indicate control commands, and broken arrows indicate inspection data.

In the embodiment, in order to generate the inspection data, the predetermined terminal of the connector CNi of the sub control board is directly connected to the ground, but instead of this, it may be connected to the ground via a resistor. In this case, it is needless to say that the resistance ratio to the pull-up resistor is appropriately determined and the voltage value supplied to the input port section 54b by the voltage division is set to the L level.

In the embodiment, the inspection data is checked only once in the main processing, but instead of this configuration, as shown by the broken line in FIG. 8, the inspection data is repeatedly checked as a part of the infinite loop processing. Is also good. In this case, the processes of steps ST40 and ST41 of FIG. 10 can be omitted, and in the timer interrupt that should be completed within a limited time (it is necessary to complete all the processes within 2 mS at the maximum). This has the advantage of increasing the time that can be allocated to processing.

[0059]

As described above, according to the present invention,
It is possible to realize a gaming machine that can detect an abnormal situation such as a connection failure without performing bidirectional communication of control commands between the main control unit and the sub control unit.
