Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine in which a plurality of control commands are unidirectionally communicated from a control unit to a controlled unit in a setting order, and the controlled unit performs an operation specified by each command. In particular, the present invention relates to a method in which the controlled means can check the reception order of a plurality of received control commands and the operation order based on the received plurality of control commands to determine whether an error has occurred.

[0002]

2. Description of the Related Art In a pachinko machine, which is a ball-and-ball game machine, control of gaming objects such as a symbol starting means and a large winning means provided on a game board, control for detecting a prize in a prize means, and a display for design display Various control such as symbol display control to a plurality of symbol display units provided in the game, payout control of a game ball with a prize to a prize means, sound control at the time of a prize or a big hit state, furthermore, firing control by operating a firing handle, etc. A control device for controlling is provided.

[0003] In this control device, a main control section mainly for controlling a plurality of gaming objects provided on a game board is provided with a symbol control section mainly for controlling a symbol change to a display in a series of display control for display control. It is controlled directly by the control signal. This command transmission is performed by one-way communication from the main control unit to each control unit to prevent fraud. For example, the main control unit, for each symbol display unit of the display, at the time of power-on, each transmits the symbol designation data for the initial display symbols, when the game ball wins the symbol start means,
A scroll speed command signal is transmitted, a plurality of types of symbols are scrolled and displayed at any one of a high speed, a medium speed, and a low speed. A command is issued to delay the scroll display from a point a predetermined screen before the stop symbol, and the stop symbol is displayed with the stop symbol.

In this case, since a detailed control signal for each operation is transmitted to the symbol control unit one by one to control the display, even if one control signal is lost due to noise, static electricity, or the like, the subsequent control signal follows. Since the display operation can be continued by the control signal, the symbol control unit does not check for a communication error.

In the above-described control using detailed control signals for each operation, since the number of control signals is large, management of control signals and checking of control have been complicated. As a countermeasure, it is conceivable to adopt a control method capable of reducing the number of control signals. For example, on a symbol control board, data of a plurality of types of variation patterns for symbol variation (data of a variation control pattern including setting data such as scroll display speed and variation time for each of a plurality of symbol display units), symbol display Display data for a plurality of screens relating to display of data, scroll symbol display data for changing symbols by scrolling, and the like are stored in advance.

The main control unit transmits a symbol change command (including a change pattern designation number) for design change to the design control unit at the time of design change, and displays the design in a change pattern according to the specified pattern. . Then, at the time of the symbol change stop, a symbol stop command for instructing to stop the display with the stop symbol is transmitted to each symbol display unit, and each symbol display unit is sequentially stopped at the designated symbol. As a result, the symbol variation control can be simplified, and the control check can be simplified.

[0007]

However, when the number of commands is reduced, when a reception error occurs, a display problem occurs. For example, at the time of symbol change, the main control unit sends a change pattern designating command and a 3
The left symbol designation command, the middle symbol designation command, and the right symbol designation command that specify the stop symbol are transmitted multiple times for one symbol display unit, and when these control commands are received by the symbol control unit, they are received first. If the changed pattern designating command changes to an invalid signal due to noise, the pattern change cannot be started. In addition, when the first variation pattern designation command is normally received but any of the symbol designation commands received thereafter changes to an invalid signal, the symbol variation in any of the symbol display units is stopped by a predetermined stop symbol. Causes various malfunctions such as an inability to stop.

An object of the present invention is to check the reception order of a plurality of control commands transmitted from a control means and received by a controlled means, and to determine whether an error has occurred by checking the operation order based on the received plurality of control commands. An object of the present invention is to provide a ball game machine capable of notifying the occurrence of a communication error or an operation error.

Next, various functions achieved through a plurality of control programs stored in advance in the control device of the pachinko machine 1 will be described with reference to a functional block diagram of FIG. However, these various functions are achieved by a microcomputer including a CPU, a ROM, a RAM, and the like. here,
The main control board 27 functions as main control means 30 mainly controlling the various game components provided on the game board 4, and the symbol control board 28 controls the symbols of the first symbol display means 14 in a variable manner. Function as

Main control means (this corresponds to the control means)
Numeral 30 mainly controls the various game components provided on the game board 4, and includes a random number generating means 31, a random number determining means 32, a display symbol lottery means 33 and the like. The random number generating means 31 counts a predetermined number (for example, 0 to 319) by a ring counter, and when the symbol starting means 23 wins, the count value at the timing when the symbol starting signal is supplied from the symbol starting means 23. Is supplied to the random number determination means 32 as a random number value.

The random number determining means 32 determines whether the random number value supplied from the random number generating means 31 is "big hit" or "losing". If the random number is a preset random number (for example, 100), it is determined to be "big hit", and if it is any other random number, it is determined to be "losing".

The display symbol lottery means 33 includes the random number determination means 3
According to the determination result from No. 2, one of a plurality of types of variation patterns is set by a predetermined lottery program,
Further, from among a plurality of types of display symbols, one of the jackpot symbols is set by random selection when the random number value is “big hit”, and one of the loss symbols is set by lottery when the random value is “loss”. , A variation pattern designation command for designating these variation patterns, a left symbol designation command, a middle symbol designation command, a right symbol designation command, and a symbol stop command for designating "big hit" or "losing". Send in order.

A symbol control means (which corresponds to a controlled means) 34 for displaying a symbol on each of the symbol display portions 14a to 14c and for controlling the variation of the symbol is provided with data of a plurality of types of variation patterns for symbol variation. Three symbol display parts 14a-1
4c, data of a fluctuation control pattern including setting data such as a scroll display speed and a fluctuation time), symbol display data, scroll symbol display data for varying symbols by scrolling, etc. Display data is stored in advance. Symbol control means 3
4 is a symbol variation control when a game ball is won in the symbol starting means 23, receives a variation pattern designation command from the display symbol lottery means 33, and sequentially receives the symbol designation commands of the symbol display sections 14a to 14c. (See FIGS. 5 and 6).

In the symbol variation control, first, each of the symbol display sections 14a to 14c based on a variation pattern designation command.
Is changed for a predetermined time, and then the left symbol, the middle symbol, and the right symbol are set in the order specified by the symbol designating command based on each symbol designating command. As will be described later, the symbol control unit 34 includes an error determination unit 35, a reception history storage unit 36, a notification unit 37 for notifying the occurrence of an error, and the like.

Next, a symbol variation control routine executed by the symbol control means 34 will be described with reference to the flowcharts of FIGS. When the power of the pachinko machine 1 is turned on, an initial screen is first displayed on the first symbol display means 14 and then this control is started.
When the control command relating to the symbol variation is not received from (S1: No), S1 is repeated until the command is received to prepare for the start of the game. When a game is started and a game ball wins in the symbol starting means 15, as described above, the main control means 30 executes a fluctuation pattern specifying command obtained based on a random value at the timing when the symbol starting means 15 is won. And a left symbol designation command, a middle symbol designation command, a right symbol designation command, and a symbol stop command are transmitted in one direction in this setting order.

That is, when a variation pattern designation command is first received (S1, S2: Yes), the scroll display speed of each of the symbol display sections 14a to 14c included in the variation pattern designated by the variation pattern designation command. And each symbol display unit 14a to 14c based on the
Are set (S7). as a result,
Each symbol display unit 1 is operated by a variation control subroutine (not shown).
For each of 4a to 14c, the symbol variation control based on the scroll display speed is executed independently over the set variation time. Next, the symbol change flag CF is set and stored in the reception history storage unit 36 (S8), the communication error flag EF is reset, and similarly stored in the reception history storage unit 36 (S9).

Next, when the left symbol designating command is received (S3: Yes), the symbol changing flag CF is set (S10: Yes), and the left symbol is not displayed as "x" (S3).
11: No), a left stop symbol displayed on the left symbol display section 14a specified by the left symbol designation command is set and stored in the reception history storage section 36 (S12). Next, when the middle symbol designating command is received (S4: Yes), the symbol changing flag is set.
CF is set (S13: Yes), and the middle symbol is "x"
When the left stop symbol is not set (S14: No) and the left stop symbol is set (S15: Yes), the middle stop symbol displayed on the middle symbol display section 14b designated by the middle symbol designation command is set and the reception history is stored. It is stored in the unit 36 (S17).

Next, when the right symbol designating command is received (S5: Yes), the symbol changing flag CF is set (S18: Yes), and the right symbol is not displayed as "x" (S19:
No), a left stop symbol is set (S20: Yes), and a middle stop symbol is also set (S22: Yes).
), Right symbol display unit 1 specified by right symbol designation command
The right stop symbol to be displayed in 4c is set and stored in the reception history storage unit 36 (S24). Next, when a symbol stop command (this corresponds to a specific command) is received (S6: Yes), the symbol changing flag CF is set (S25: Yes), and the left stop symbol is set ( S2
6: Yes), the middle stop symbol is also set (S28: Yes)
), When the right stop symbol is also set (S3
0: Yes), the symbol changing flag CF is reset (S3)
2).

The fluctuation time of the symbols elapses in each of the symbol display sections 14a to 14c, and the symbols are stopped at the individually set stop symbols as the left symbol, the middle symbol, and the right symbol, and the symbol variation control ends normally. For example, at the time of a big hit, for example, “7, 7, 7” is displayed as the left symbol, the middle symbol, and the right symbol. As a result, the open / close plate 18a of the special winning means 18 is opened and the game balls can be won, and every time the special winning means 18 is won, a predetermined number of game balls are paid out to the upper plate 7 by the payout means 23. Here, in the symbol variation control,
The error determination unit 35 is composed of S15, S20, S22, S26, S28, S30, and the like, and the reception history storage unit 36 is composed of S8, S12, S17, S24, and the like.

That is, when the symbol is changed, the main control means 30
To the symbol control means 34, a fluctuation pattern designation command, a left symbol designation command, a middle symbol designation command,
When the right symbol designation command and the symbol stop command are transmitted in one direction in this setting order, the symbol control means 34 controls a plurality of control commands (variation pattern designation command, left symbol designation Command, middle symbol designation command, right symbol designation command and symbol stop command) only when received in the set order,
Since no error is determined by the error determination unit 35, the symbol variation is executed in the first symbol display unit 14 based on the received control command group, and operations such as stopping the variation symbol are executed in a normal order. be able to.

By the way, since the main control board 27 and the symbol control board 28 are connected by a plurality of signal lines via the connectors provided respectively, the main control means 30 sends a series of plural signals such as a variation pattern designating command. If the command is sent in the setting order and the command is changed to an invalid command (data) due to the influence of noise from the connector connection, signal line, external static electricity or electromagnetic waves, an error judgment is made. Can be an error.

That is, at the start of the symbol variation control, the variation pattern designation command to be received first cannot be received, and any of the left symbol designation command, the middle symbol designation command, the right symbol designation command, and the symbol stop command is executed. When the symbol is received for the first time, the symbol change flag CF is not set (S10: No, S13: No, S18: No, S25: No).
The communication error flag EF is set (S33). As a result, since the order of the received plural commands is not as set, an error message such as "communication error occurred" is displayed on the liquid crystal display unit 13, and the occurrence of the error can be surely recognized.

On the other hand, although the fluctuation pattern designation command is received first, the left symbol designation command to be received next cannot be received, and thereafter, the middle symbol designation command, the right symbol designation command, and the symbol stop command are received. If the order of receiving these four commands is different from the setting order, such as receiving any of them first, and the symbol settings of the symbol display sections 14a to 14c do not correspond to the setting order (S15: No, S2
0: No, S22: No, S26: No, S28: No, S30: No),
It is set so that the mark "x" is displayed on the left symbol, the middle symbol, and the right symbol (S16, S21, S23, S27, S29, S3
1). Here, the determinations in S15, S20, S22, S26, S28, and S30 are determinations as to whether or not there is an error based on the operation history corresponding to the type of the command received last time.

That is, even if any of a plurality of control commands following the variation pattern designation command is changed to a meaningless invalid command (data) under the influence of noise from external static electricity or electromagnetic waves, Similarly, since the order of the plurality of control commands received by the symbol control means 34 is different from the setting order, the occurrence of an error is notified by displaying a mark such as “x” indicating a malfunction. Here, the S
16, S21, S23, S27, S29, and S31 constitute the notifying means 37.

In the pachinko machine 1 described above, a plurality of commands relating to symbol change and symbol stop are transmitted from the main control means 30 to the symbol control means 34 in the set order, and these are transmitted by the error determination section 35 of the symbol control means 34. It is not an error if a plurality of commands are received one after another in the set order, but an error if received in an order different from the set order.

In other words, the main control means 30 does not generate an error if the commands are operated in an appropriate order corresponding to the setting order of these commands, but generates an error if the commands are received in an order different from the setting order. Even when the control command is transmitted to the means 34 in one direction, the correctness and reliability of the operation order based on the received plurality of control commands and reliability can be easily checked by the symbol control means 34, and the malfunction in the symbol control means 34 can be surely confirmed. Can be prevented.

Since the reception history storage unit 36 stores the data of the symbol change flag CF and the symbols stopped by the symbol display units 14a until the next error determination, the reception history storage unit 36 stores the data. Based on the type of the received command or the data of the symbol-in-change-of-symbol flag CF (corresponding to information related to the command) stored in the memory 36, error determination in the next time can be easily and accurately performed.

Further, when a symbol stop command is received at the end of the symbol change, the symbol is determined based on the actual operation history executed before the previous time, which is the setting state of the left stop symbol, the middle stop symbol, and the right stop symbol. An error determination can be made as to whether or not the fluctuation control can be normally terminated, and a malfunction of the symbol control means 34 can be reliably prevented. Further, when the determination result by the error determination unit 35 is an error, the notifying unit 37 for notifying the error is provided, so that an error mark "x" is displayed on the symbol display unit 14a where the error is detected.
The occurrence of an error can be clearly understood.

The present invention is not limited to the above-described embodiments, and can be implemented in variously modified forms without departing from the spirit of the present invention. 1) When an error is detected, various marks or symbols indicating an error unrelated to the game may be displayed instead of the display of "x", and a buzzer sounds or an alarm sound is generated from a speaker. Alternatively, the notification may be made by vibrating the pachinko machine 1 or the like.

2) In the symbol variation control, S15, S20,
Each of S26 is changed to "Is a left symbol designating command received?", And each of S22 and S28 is changed to "Is a middle symbol designating command received?", And S30 is changed to "Are right symbol designating command received?" And an error may be determined based on the type of command. 3) Each of S10, S13, S18, and S25 may be changed to "Did you receive a fluctuation pattern designation command?", And an error may be determined based on the type of command.

4) The present invention can be applied to the case where the voice output command is transmitted in one direction from the main control means 30 to the sound control board, and the case where the lighting control command and the blinking drive command are transmitted in one direction from the main control means 30 to the lamp control board. May be applied. 5] When the error determination unit 35 determines that an error has occurred, the error information may be transmitted to and output to an island-side computer provided in a game arcade. 6] A case may be used where two-way communication of commands and control signals is performed between the main control means 30 and various controlled means such as the symbol control means 34 and the sound control board. 7] The present invention is not limited to pachinko machines, but can be applied to various ball game machines such as arrange ball machines and sparrow ball machines.
