In addition, when the game ball that has been launched when there is a notification of the timing of the start of operation reaches the position of the winning device through a predetermined route on the game board, the winning device is converted to the first state. Yes. Therefore, the player reaches the position of the winning device in the second state before being converted to the first state by starting the release of the game ball when the timing of the operation start is notified. It is possible to prevent the game ball from being fired. In other words, by launching a game ball in accordance with the notification, it is possible to add a new interest to the game that the game can be advantageously advanced. Furthermore, the player advances the game with an unprecedented sense of tension.
[0015]
Further, when a game ball that has been fired after the operation stoppage time reaches the position of the winning device through a predetermined route on the game board, the winning device is in the second state. Therefore, it is possible to prevent the launch of the game ball that reaches the position of the winning device in the state after the transition from the first state to the second state. In other words, by launching a game ball in accordance with the notification, it is possible to add a new interest to the game that the game can be advantageously advanced.
[0016]
In addition to notifying when the operation is started, the player is also notified that the time is near, so that the player can prepare for the start of the operation, and can reliably start firing the game ball at the operation start time.
[0017]
In addition to notifying when the operation is stopped, the player is also notified that the time is near, so that the player can prepare for the operation stop and reliably stop the game ball from being released at the operation stop time.
[0018]
The game state determination means determines whether or not to shift to the special game state when a game ball wins the winning device. Therefore, the player can advantageously advance the game by notifying the timing of the operation, and can obtain an opportunity to shift to the special game state by winning the winning device. In addition, since the notification and the variation display of the special symbol are associated with each other through the determination of the special game state determination means, it is possible to realize game integrity.
[0019]
Further, the notifying means performs a variable display of a plurality of special symbols based on the determination result of the special gaming state determining means. In other words, since the timing notification and the fluctuation display are realized by one means, the player does not miss either the timing notification or the fluctuation display.
[0020]
In addition, the notification can be performed in a probability variation state in which the probability that the special game state determination unit determines to shift to the special game state is high.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
A pachinko machine according to an embodiment of the present invention will be described.

FIG. 1 is a front view showing a pachinko machine 1. Near the center of the game area (game board) 3 provided in the pachinko machine 1, a liquid crystal display device 4 constituting a notification means and a display means for variably displaying a plurality of special symbols is arranged. The liquid crystal display device 4 performs a variable display of a plurality of symbols (for example, three columns on the left, center, and right) represented by an image, a firing start / continuation display described later (FIGS. 2 to 5), and the like. The special symbol displayed on the liquid crystal display device 4 starts to be displayed in a variable manner when a game ball wins a start winning opening 6 described later. When the combination of the three special symbols displayed in a stopped state becomes, for example, “7-7-7”, a transition is made to a special gaming state (big hit) that is advantageous to the player. Here, the odd number of special symbols is hereinafter referred to as “specific symbols”. The even number of special symbols is hereinafter referred to as “non-specific symbols”. Whether or not to shift to the special game state is determined by a main control circuit 74 (FIG. 7) described later.
[0023]
Also, in the embodiment, the probability of transition to the special gaming state changes after the special gaming state is ended (so-called “probability fluctuation”) after the special gaming state is ended depending on the symbol combination that causes the transition to the special gaming state. It has become. When the special game state is generated by the combination of “specific symbols”, the probability of the next transition to the special game state is “1 / 63.1”. On the other hand, in the case of the “non-specific symbol”, the probability is “1 / 315.5”. Here, the gaming situation in which the probability of shifting to the special gaming state is “1 / 63.1” is hereinafter referred to as “probability fluctuation state”. A gaming situation in which the probability of shifting to the special gaming state is “1 / 315.5” is hereinafter referred to as “normal state”.
[0024]
Below the liquid crystal display device 4, an ordinary electric accessory 5 constituting a start winning opening (so-called start hole) 6 is provided. The ordinary electric accessory 5 has a first state (hereinafter referred to as “open state”) that is easy to win the start winning opening 6 and a second state (hereinafter referred to as “closed state”) that is difficult to win the start winning opening 6. This is a winning device (so-called tulip) having a convertible opening / closing blade. The ordinary electric accessory 5 wins a later-described ordinary symbol, and changes to an open state when a display time (FIG. 6) after determining the ordinary symbol has elapsed. Even when the open / close wing piece is closed, about one game ball (pachinko ball) can be won. When the game ball wins the start winning opening 6, five prize balls are paid out. The time during which the ordinary electric accessory 5 can be kept open is “4020 [ms]” in the probability variation state and “300 [ms]” in the normal state. The ordinary electric accessory 5 is changed to a closed state when one game ball is won.

When all the notification areas 36 become the blue area 38, the start / continuation display of the firing is started. In this firing start / continuation display, a red area (hereinafter referred to as “red area”) 39 increases from the right side to the left side of the notification area 36. When all the notification areas 36 are red areas 39, the emission stop display is displayed.
[0041]
Next, referring to the timing chart shown in FIG. 6, the timing at which the main control circuit 74 (described later) (FIG. 7) transmits a command (information or command), the normal symbol mode, and the normal electric accessory 5 mode And the display mode of the liquid crystal display device 4 will be described. The normal symbol variation command is a command transmitted by the main control circuit 74 described later to the liquid crystal drive circuit 91 (ST50 in FIG. 12 described later) when the normal symbol is won. The normal symbol determination command is a command that the main control circuit 74 described later transmits to the liquid crystal drive circuit 91 when the variation display of the normal symbol is stopped.
[0042]
Here, the time from when the normal symbol starts changing until it stops is hereinafter referred to as “normal symbol change time (“ 6000 [ms] ”in the embodiment)”. The time from when the change of the normal symbol stops until the normal electric accessory 5 changes to the open state is hereinafter referred to as “display time after determining the normal symbol (“ 504 [ms] ”in the embodiment)”. The time during which the ordinary electric accessory 5 is in the open state is hereinafter referred to as “ordinary electric accessory release time (“ 4020 [ms] ”in the embodiment)”. The time during which the firing preparation display is performed is hereinafter referred to as “launch preparation display time (in the embodiment,“ 2000 [ms] ”). The time during which the firing start / continuation display is performed is hereinafter referred to as “launching start / continuation display time (in the embodiment,“ 4000 [ms] ”). The time during which the firing stop display is performed is hereinafter referred to as “a firing stop display time (“ 1000 [ms] ”in the embodiment”). The time from when the normal symbol starts to fluctuate until the launch preparation display is performed is hereinafter referred to as “time X (in the embodiment,“ 1000 [ms] ”).
[0043]
After the normal symbol variation command is transmitted and the normal symbol variation starts, when the time X has elapsed, a fire preparation display is performed. When the firing preparation display time has elapsed, the firing start / continuation display is performed. The timing at which the firing start / continuation display is started is before the arrival time of the timing at which the ordinary electric accessory 5 changes to the open state. Also, the firing start / continuation display time is equal to the normal electric accessory opening time. When the normal symbol variation time ends and the display time after the normal symbol determination has elapsed, the ordinary electric accessory 5 changes to the open state. The firing start / continuation display time ends before the arrival time when the normal electric accessory release time ends, and the firing stop display is performed. In addition, after the ordinary electric accessory 5 changes to the closed state, an ordinary symbol variation waiting time (“6 [ms]” in the embodiment) (not shown) is provided. The normal symbol variation waiting time is determined by the time until the normal symbol starts to change after the normal electric symbol 5 is elected and the normal electric accessory 5 changes to the closed state (ST94 in FIG. 15 to be described later), and the normal symbol. This is the time (ST86 in FIG. 14 to be described later) until the normal symbol starts to change after the normal symbol display LED 12b is turned on.
[0044]
As described above, the firing start / continuation display time is equal to the normal electric accessory opening time. In addition, the start time of the firing start / continuation display time is earlier by the arrival time than the start time of the ordinary electric accessory opening time. For this reason, during the launch start / continuation display time, a game ball is fired to win a prize for the ordinary electric accessory 5 and win a prize ball, and a special symbol change display is realized, and a transition to a special game state is realized. You can get an opportunity. In addition, the game ball is stopped during the period other than the start / continuation display time, so that the game ball reaches the position of the ordinary electric accessory 5 when the ordinary electric accessory 5 is in the closed state. The inconvenience of firing a sphere can be avoided.
[0045]
FIG. 7 is a block diagram illustrating a configuration of an electric circuit unit of the pachinko machine 1.
[0046]
As shown in this figure, the pachinko machine 1 according to the embodiment has a gate switch 70 that detects a game ball that has passed through the above-described normal symbol operating gate 7 and a game ball that has won a prize in the above-described general winning ports 31a and 31b. A general winning ball sensor 71 for detecting, a starting winning ball sensor 72 for detecting a gaming ball winning in the aforementioned starting winning port 6, and a big winning ball sensor 73 for detecting a gaming ball winning in the aforementioned big winning port 8. Is provided.
[0047]
The operation of the pachinko machine 1 is controlled by a main control circuit 74 constituting main control means disposed on the circuit board. The main control circuit 74 includes a central processing unit (CPU) 75 as a main component, and includes input / output ports (I / O ports) 76a and 76b serving as interfaces between the sensors and drive circuits described later. A ROM 77 as a read-only storage means and a RAM 78 as a readable / writable storage means are connected. As the RAM 78, a dynamic memory (DRAM) is used.
[0048]
Further, the main control circuit 74 generates a reset signal for executing the entire game control processing program periodically (for example, every 2 ms) (this is referred to as “interrupt generation”), a reset clock pulse generation circuit 79, And an initial reset circuit 81 for generating an initial reset signal for executing an initial process for the circuit when the power is turned on.
[0049]
The CPU 75 includes a jackpot determination random number counter 82, a jackpot symbol determination random number counter 83, a loss symbol determination random number counter 84, a variation pattern number determination random number counter 85, a normal symbol storage counter 86, and a normal symbol determination random number counter 87. Have
[0050]
The jackpot determination random number counter 82 is used to determine whether or not to shift to the special gaming state, and repeats addition at a predetermined time interval (here, every time an interrupt signal is generated), and is initialized with a constant value ( Reset to 0). The jackpot symbol determining random number counter 83 is used to determine three special symbols to be stopped and displayed when it is determined that the game state is shifted to the special gaming state (big jackpot). The random symbol counter for losing symbol determination 84 is used to determine three special symbols to be stopped and displayed when it is determined that the game state does not shift to the special gaming state. The variation pattern number determination random number counter 85 is used when determining the variation pattern number associated with the variation pattern of the special symbol.
[0051]
The normal symbol storage counter 86 stores the number of times the normal symbol including the currently changing symbol can be changed. Specifically, the detection signal from the gate switch 70 is counted up to “5” (ST22 in FIG. 10 described later). Further, the value of the normal symbol storage counter 86 is basically subtracted by “1” when the variation of the normal symbol is stopped (ST106 in FIG. 16 described later). The normal symbol per-determination random number counter 87 is used to determine whether or not the normal symbol is won, that is, whether or not the normal electric accessory 5 is opened. Specifically, when “1” is added (counted) to the normal symbol storage counter 86, a random number is extracted from the normal symbol per-determination random number counter 87 (ST23 in FIG. 10 described later).
[0052]
The RAM 78 has a normal symbol storage area corresponding to the normal symbol storage counter 86. In the normal symbol storage area, the random value extracted from the normal symbol per-determination random number counter 87 is stored. Further, in a predetermined storage area of the RAM 78, a flag such as a normal symbol stop flag described later is set or cleared. Setting the flag means storing information indicating “1” in the storage area. Clearing the flag means storing information indicating “0” in the storage area.
