Description

  The present invention relates to a ball game machine.

  In general, in a ball game machine such as a pachinko game machine, a special symbol displayed on the display device when a game ball launched into the game area of the game board passes a specific winning opening (start winning opening). Fluctuation (electronic validity lottery) is started. When the winning / losing lottery is won, a combination of predetermined special symbols is displayed on the display device, and a jackpot gaming state advantageous to the player is generated. In the jackpot gaming state, the special winning opening (big winning opening) opens and closes to accept gaming balls, so that the player can acquire many winning balls.

  In addition, if an error or a power failure occurs in a ball game machine while the player is playing a game, the ball game machine is forcibly stopped. preferable.

  Here, as a structure for maintaining a gaming state at the time of a power failure, Japanese Patent Application Laid-Open No. 2002-119707 describes a structure for temporarily holding a game ball on a sensor of a winning opening at the time of a power failure. According to this structure, a prize ball by a game ball won at the time of a power failure is compensated after the game is resumed.

JP 2002-119707 A

  However, in the above-described conventional structure, only the winning game balls are put on hold, and therefore, for example, the game balls before winning are not put on hold. For this reason, for example, when an opening / closing member that opens and closes between an open position that guides the game ball to the winning opening and a closed position that does not guide it is provided, the opening / closing member is forcibly set to the closed position in the event of a power failure. This makes it difficult for the game ball to enter the winning opening, which is disadvantageous for the player.

  In addition, when there are a plurality of winning holes, it is necessary to provide a structure for holding a game ball at each winning hole, which causes a complicated structure of the game board.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a ball game machine capable of reducing a player's disadvantage when a forced game is stopped by a simple structure. It is to provide.

  In order to achieve the above object, a first aspect of the present invention is a bullet ball game machine having a game area in which a game ball falls on the surface of a game board, comprising a fall prevention member, a winning opening, and a control means. Prepare.

  The fall prevention member is provided movably between a fall prevention position that protrudes into the game area and a fall allowance position that does not protrude beyond the fall prevention position. At the fall prevention position, the game area is separated from the upper first area and the lower area. The game ball is divided into the second region to prevent the game ball from falling from the first region to the second region, and the game ball is allowed to fall from the first region to the second region at the drop allowable position.

  The winning opening is provided in the second area of the game area, and triggers a lottery execution as to whether or not the entry of the game ball causes a game state advantageous to the player.

  The control means sets the fall prevention member to the fall prevention position when the bullet ball game machine is in a predetermined state, and sets the fall prevention member to the fall permission position when the bullet ball game machine is not in the predetermined state.

  In the above configuration, when the ball game machine shifts to a predetermined state (for example, forced game stop state) and the game is interrupted while the player is playing a game, the control means drops the fall prevention member. Set to blocking position. The fall prevention member holds the game ball launched into the game area in the first area above the second area where the winning opening is provided. Then, when the predetermined state is released and the game is resumed, the control means sets the fall prevention member to the fall allowable position. By the movement of the fall prevention member, the game ball held by the fall prevention member falls to the second area where the winning opening is provided.

  As described above, among the game balls that have been launched into the game area, the game balls that are likely to win the winning hole are held above the winning hole by the fall prevention member, so that the game at the time of transition to the predetermined state The game balls in the area can be maintained in a state that is unlikely to be disadvantageous for the player after the predetermined state is released and the game is resumed. For example, when an opening / closing member that opens and closes between an open position that guides a game ball to a winning opening and a closed position that does not guide it is provided, the opening / closing member is forcibly set to a closed position in a predetermined state. However, the reserved game ball is given a chance to win in a state in which the predetermined state is released and the opening and closing member can be opened and closed.

  Further, even when a plurality of winning holes are provided in the second region, it is not necessary to provide a fall prevention member corresponding to each winning hole, so that the structure can be simplified.

  Further, the predetermined state may be at least one of a power interruption state where power supply to the ball game machine is cut off and an error state where an error has occurred in the ball game machine.

  According to the above-described configuration, when the ball game machine is in a power interruption state or an error state, the game balls in the game area are maintained in a state that is unlikely to be disadvantageous for the player after the game is resumed.

  A second aspect of the present invention is the bullet ball game machine according to the first aspect, and includes a fired ball reservoir, a collection hole, and a collection passage.

  The shot ball storage unit stores game balls that are launched into the game area. The collection hole is formed in the game board and opens in the game area. The collection passage communicates the projecting ball reservoir and the collection hole. The fall prevention member is inclined toward the collection hole at the fall prevention position, and guides the game ball that has prevented the fall to the second region to the collection hole.

  In the above configuration, the game ball held by the fall prevention member is collected from the collection hole through the collection passage to the firing ball storage unit. Accordingly, the player can fire the collected game balls again into the game area after the game is resumed.

  A third aspect of the present invention is the bullet ball game machine according to the first aspect, wherein the fall prevention member has a movement restricting portion that restricts the movement of the game ball that has been prevented from dropping into the second region.

  In the above configuration, since the movement of the game ball held by the fall prevention member is restricted by the movement restricting unit, the fall of the game ball is resumed from the vicinity of the game ball fall path at the time of transition to the predetermined state. be able to.

  A fourth aspect of the present invention is the ball game machine according to any one of the first to third aspects, and includes a second fall prevention member.

  The second fall prevention member is provided movably between a fall prevention position that protrudes into the first area of the game area and a fall allowance position that does not protrude beyond the fall prevention position, and the first area is located above the fall prevention position. The game ball is divided into a lower region and a lower region to prevent the game ball from falling from the upper region to the lower region, and the game ball is allowed to fall from the upper region to the lower region at the drop allowable position. The control means sets the second fall prevention member to the fall prevention position when the ball game machine is in a predetermined state, and allows the second fall prevention member to fall when the ball game machine is not in the predetermined state. Set to position.

  In the above configuration, the game balls in the upper area of the first area are held by the second fall prevention member, and the game balls in the lower area are blocked by the fall prevention member. In other words, the game balls in the first area are held in the upper and lower areas in stages, so that the change in the position of the game balls in the vertical direction when shifting to a predetermined state is kept small. Thus, the fall of the game ball can be resumed.

  According to the present invention, it is possible to reduce the disadvantage of the player when the game is forcibly stopped with a simple structure.

When the switch is on, the CPU 13a of the main control device 13 deletes the processing information stored in the RAM 13c such as prize ball information and game history information as unnecessary residual data, and stores predetermined processing information in the RAM 13c. It is checked whether or not it can be stored normally. If the check result indicates that the data can be stored normally, the CPU 13a of the main control device 13 permits the shift to the main routine process and notifies the sub control device 14 of the start of the main control activation. Process information etc. are generated.

  On the other hand, if the switch is not on, the CPU 13a of the main control device 13 determines whether or not the backup flag is set. If the backup flag is set, the same check and Permits transition to main routine processing. On the contrary, when the backup flag is not set, the CPU 13a of the main control device 13 determines whether or not the processing information (the contents of the storage area) stored in the RAM 13c is broken and stores it in the RAM 13c. If it is determined that the processed information is not “broken”, the same check as described above and the transition permission to the main routine processing are performed.

  On the other hand, when it is determined that the processing information stored in the RAM 13c is “broken”, the CPU 13a of the main control device 13 generates an unforeseen power failure, failure, processing error, etc. before the power is turned on. It is determined that the error has occurred, and after the error cancellation recovery process is performed, control is performed to start the process from the point of power-off when the error occurred.

  Here, the main routine processing in the present embodiment is executed by a control program (computer program) stored in advance in the ROM 13b provided in the main control device 13. Then, the CPU 13a of the main control device 13 performs, as main routine processing, random number update processing, input detection reception processing, input management processing, abnormality monitoring processing, special symbol control processing, normal symbol control processing, lamp management processing, and preparation ball payout processing. External information management processing and output management processing are performed.

  The main routine processing is to generate a periodic timing pulse (for example, 4 milliseconds) by frequency division setting based on a periodic signal generated by the frequency generation circuit unit 13d, and to match the generated timing pulse. The CPU 13a is a basic routine that repeatedly executes a control execution process including reading and updating of each process, writing storage, deletion of the storage, and the like.

  Hereinafter, among the main routine processing, input detection reception processing, input management processing, abnormality monitoring processing, special symbol control processing, normal symbol control processing, and output management processing will be described.

This is a process of monitoring whether there is input information generated by each detection sensor 47 of the detection sensor 47g according to a timing pulse (for example, 4 milliseconds) and receiving the input information from each detection sensor 47.

"Input management process"
The input management process analyzes the input information received by the input detection reception process, and, for example, according to the analysis result such as from which detection sensor the input signal is, Performs processing such as counting management of game balls and time management from the time of reception related to winning detection until control processing based on winning is started, abnormality monitoring processing, special symbol control processing, normal symbol control processing, lamp This is a process that makes it possible to use the processing results as appropriate in performing the management process and the prize ball payout process.

  Here, the error processing information generated by the input management process in accordance with the information generated by the error detection sensor 47g in the present embodiment includes an error (empty error) when a shortage of gaming balls for prize balls is detected, and a passage. An error when detecting a ball jam in a prize ball (ball jam error), an error when an overflow of the ball tray 9 is detected (overflow error), and a ball lending relationship for instructing a lending lending process An error when detecting a malfunction of the button of the operation unit 11 (a lending button error), an error when detecting a malfunction of the CPU 13a of the main control device 13 (a CPU error), and an opening of the front door This is processing information with an error (door opening error).

"Abnormality monitoring process"
In the abnormality monitoring process, whether or not various error processing information is generated in the input management process is monitored and determined according to a timing pulse (for example, 4 milliseconds), and error processing information is generated. In this case, it is a process of generating error notification process information in an output mode corresponding to the error process information. In this abnormality monitoring process, the CPU 13a of the main control device 13 also generates error release notification process information of an error release output mode when the error management release process information is received by the input management process.

  Then, the CPU 13a of the main control device 13 transmits the generated notification processing information to the sub-control device 14 side, and stores the notification processing information as an error notification output mode in the abnormality monitoring processing (for example, RAM 13c). To remember. Note that the notification process information stored for transmission to the sub-control device 14 side means, for example, a “preceding command number” meaning an abnormality monitoring process in a normal gaming state and an error output mode of notification to be executed. It consists of a combination with the “following command number”. Hereinafter, the processing information generated in the main routine processing is a combination of a “preceding command number” meaning what processing in what gaming state and a “following command number” meaning a predetermined output mode to be executed (hereinafter, Simply referred to as a number or a command number).

"Special symbol control process"
In the special symbol control process, an electronic winning / losing lottery is performed in response to receiving input information from the specific winning ball detection sensor 47a provided in the vicinity of the specific winning opening 2, and in the case of winning, a normal game This is a process for making it easy for the game ball 66 to win the special winning opening 3 so that the game state (big win game state) advantageous to the player from the state. In this special symbol control process, the CPU 13a of the main control device 13 also performs a process related to display control of identification display information (hereinafter referred to as a special symbol) by the variable display device 34.

"Normal design control processing"
The normal symbol control process is a process for making the game state advantageous to the player, and electronic determination of lottery in response to receiving input information from the passing ball detection sensor 47d provided in the vicinity of the predetermined passing port 38. In the process of winning, the movable pieces 44 provided on both sides of the entrance of the specific prize opening 2 are enlarged, the opening range is enlarged, and the launched game ball 66 is easily entered into the specific prize opening 2 is there. Moreover, in this normal symbol control process, the display control of the identification information called a normal symbol is also performed by the LED display device 35.

  Here, the normal symbol is a predetermined number of pieces of identification information for variably displaying or blinking the result of the success / failure lottery according to the input information from the passing ball detection sensor 47d (for example, “O · −” → winning symbol, “ − · × ”→ off symbol). When the lottery result is a win, a predetermined number of pieces of identification information are displayed in a specific combination that is stopped in a predetermined combination (for example, “O · −”), and thereby a gaming state advantageous for the player (for example, , Small hit) is notified. In such a gaming state, compared to the normal gaming state, a state in which a launched game ball is likely to win a prize occurs once or continuously. On the other hand, when the lottery result is out, the predetermined number of pieces of identification information becomes a display mode (eg, “− · ×”) that is stopped in a combination other than a predetermined specific combination, and thus the normal gaming state continues. Is informed.

By the normal symbol control process, the following information is generated as process information obtained after the passage state at the predetermined passage port 38 is achieved.
(1) A variation pattern number for winning or losing.
(2) Normal symbol number for winning or losing.
(3) A fixed stop instruction number for setting a stop display mode for a normal symbol that is variably displayed or blinked.
(4) The small hit transition instruction number in the case of winning in the determination of success or failure.

  Then, when transmitting the variation pattern number and the normal symbol number to the sub-control device 14 side through the output management processing described later, the variation control processing execution time of the variation pattern is set corresponding to the determined variation pattern. The timer that is set by the CPU 13a of the main control device 13 and performs count calculation processing is updated. It should be noted that, at a timing corresponding to the elapse of the control processing execution time by the timer, the confirmed stop instruction number and the small hit transition instruction number in the case of winning in the determination of success / failure are transmitted via the output management process.

  Further, in the normal symbol control process, when a win / no-go determination is made as to whether or not the gaming state is advantageous for the player, the winning result is notified. The notification method is performed by executing a predetermined stop display mode based on blinking display of normal symbols. In this case, the following processing is also performed.

That is, in order to achieve the advantageous gaming state corresponding to the win,
(A) The pair of movable pieces 44 that are configured to reduce the opening range with respect to the specific winning opening 2 are operated to expand the opening range for a predetermined time (for example, 0.2 seconds) (specific winning opening) 2)
(B) Then return to the original state,
Processing information for instructing to perform the above process a predetermined number of times (for example, once) is generated.

"Output management process"
The output management process is an output for transmitting processing information generated by the abnormality monitoring process, the special symbol control process, the normal symbol control process, the lamp management process, and the preparation ball payout process to the sub-control device 14 side. This is a process of editing the data and transmitting the output edited storage information together with a strobe (STB) signal for notifying the output timing of the processing information.

[Operation of sub-control unit]
Next, the operation of the sub control device 14 will be described.

  The sub-control device 14 performs an initial setting at the start of activation upon power-on, and performs a check process for necessary confirmation items. If the check processing result is normal, the shift to the main routine processing in the sub-control device 14 is permitted, and main control activation start information, which is stored information transmitted from the CPU 13a of the main control device 13, is received. .

  The main routine processing of the sub-control device 14 refers to a main control program stored in advance in a ROM provided in each of the symbol control device 14a, the lamp control device 14b, and the sound control device 14c, and a frequency generation circuit. This is a basic routine that repeatedly executes control execution processing including read update, write storage, deletion of the storage, etc. in accordance with a periodic timing pulse (for example, 4 milliseconds) generated by the unit 13d. Hereinafter, an example of basic processing in the main routine processing of the sub-control device 14 will be described.

  First, the sub-control device 14 monitors whether or not the processing information transmitted in the output management processing has been received according to the timing pulse, and if it is being received, the sub-control device 14 stores it in the storage means (for example, RAM). Remember. Next, the sub-control device 14 performs an analysis process on the received process information, and in any gaming state, any of an abnormality monitoring process, a special symbol control process, a normal symbol control process, a lamp management process, and a ball payout process It is determined which processing information (preceding command) and what kind of output mode the processing information (subsequent command number) is executed.

  Then, the sub-control device 14 sets a flag according to the result of the analysis process, sets a timer for counting based on the control process execution time according to the output mode, and stores a predetermined control program A control process for reading out and executing a control program for an output mode corresponding to the result of the analysis process from (for example, ROM) is performed.
