Abstract

PROBLEM TO BE SOLVED: To prevent a sharp shooting of single shot conducted by selecting the rotational position of a V-zone. SOLUTION: The rotary speed of a rotary board provided with a V-zone leading to a passage toward a special device operation region is raised from the rotary speed A (15 revolution/min) to the rotary speed B (50 revolution/min) in the occurrence of a big win completing the combination of normal patterns. After the passage of a predetermined time from the occurrence of the big win, a specified prize winning port is opened. When a ball enters the specified prize winning port, the rotary speed is lowered from the rotary speed B to the rotary speed C (5 revolution/min) and, when the specified prize winning port is closed, returned to the rotary speed A. Until the specified prize winning port is opened to win the prize after the occurrence of the big win, the rotary board is rotated with high speed, so that the rotary position of the V-zone gets difficult to forecast and a sharp shooting can be prevented. Also, when the ball wins the prize, the rotary speed is switched over to the low speed rotation, so that the rotational position of V-zone is different at every opening of the specified prize winning port by a prize winning timing, and further sharp shooting can be prevented, and besides ball-catching or malfunction can be prevented.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine which generates a state advantageous to a player, and more particularly, to a pachinko machine.
The present invention relates to a pachinko machine that opens a specific winning opening when a predetermined condition is satisfied, and generates a right state that is advantageous to a player when a game ball passes through a specific winning area in the specific winning opening.

[0002]

2. Description of the Related Art Conventionally, in a certain kind of pachinko machine, when a game ball passes through a gate at the center of a game board, a plurality of symbols displayed on a symbol display are usually fluctuated for a predetermined time. And so on, a case where a specific combination in which all the symbols are aligned, such as, is displayed as a jackpot.

[0003] In such a pachinko machine, when a jackpot occurs, a specific prize device provided with a rotating disk that always rotates at a constant low rotation speed sets a specific prize port (a prize port for an ordinary electric accessory). It is controlled to open. The turntable is provided with a plurality of ball storage units, and a game ball won from a specific winning opening is stored in any one of the ball storage units. These ball storage sections include a special storage section (V zone) for distributing the stored balls along the rotation of the turntable to a path to the special device operation area, and a general storage section for processing as a general prize other than the special device operation area. There is.

[0004] When game balls are stored in the V zone, when the turntable is rotated by a predetermined angle, the stored game balls are distributed to the path to the special device operation area, and a right state that is advantageous to the player is established. Occur. On the other hand, even if the game balls are stored in the general storage unit, the stored game balls are processed as a general winning and no right state is generated. Therefore, in order to generate the right state, it is necessary to fire the game balls so that one of the game balls won in the specific winning opening is stored in the V zone. At this time, the player is more advantageous as the right status is acquired with as few balls as possible.

[0005] Incidentally, the V zone and the general storage section have seemingly different shapes in order to provide the above-mentioned difference in function, and therefore, the V zone and the general storage section have a V zone through a window provided in the specific winning device. Can be determined.

[0006]

However, in the above-mentioned conventional pachinko machine, since the turntable always rotates at a constant low rotation speed, the player can easily judge the rotational position of the V zone, so that the specific winning is achieved. If the V zone is not at the rotational position where the winning ball can be stored even if the mouth is opened, the ball will not be fired,
There is a problem that the so-called aiming of firing the ball at the timing when the V zone comes to the rotation position where the winning ball can be stored can be performed.

[0007] By such aiming, the right state occurs with an extremely small number of balls, which is not preferable.

The present invention has been made in view of the above-described circumstances, and has as its object to provide a pachinko machine capable of preventing aiming at a V zone and generating a right state with an appropriate number of balls.

[0009]

In order to achieve the above object, according to the first aspect of the present invention, a specific winning opening is opened for a set time after a predetermined time elapses after a predetermined condition is satisfied. In a pachinko machine that generates a right state that is advantageous to a player when a game ball winning a mouth passes through a specific winning area, the pachinko machine is controlled to rotate at a first rotation speed until the predetermined condition is satisfied; A special prize comprising a rotating body having a general storage section and a special storage section for storing game balls having won a specific prize port, and distributing only the game balls stored in the special storage section to a path to the specific prize area. Means, and rotation control means for rotating the rotator at a second rotation speed higher than the first rotation speed from when the predetermined condition is satisfied until a game ball wins the specific winning opening, Characterized by comprising.

According to the first aspect of the present invention, when the predetermined condition is satisfied, the specific winning opening is opened for a set opening time after a predetermined time has elapsed from when the predetermined condition is satisfied. Here, as a predetermined condition,
For example, when a game ball wins a predetermined winning opening, a plurality of symbols are variably displayed for a predetermined period of time, and a condition that a combination of symbols when stopped matches the predetermined display is given as an example.

The rotation control means rotates the rotating body of the specific prize means at a second rotation speed higher than the first rotation speed from when the predetermined condition is satisfied until the game ball wins the specific prize hole. . That is, the rotating body is rotated at a higher speed than usual until the predetermined condition is satisfied and the specific winning opening is opened and the game ball wins, so that the rotation position of the special storage unit provided in the rotating body cannot be predicted. The timing to store the winning balls in the special storage unit can prevent the aiming of acquiring the right by singly playing the game balls.

According to a second aspect of the present invention, the rotation control means according to the first aspect includes a second rotation speed higher than the first rotation speed from a time when the predetermined condition is satisfied until a game ball wins at the specific winning opening. Rotating the rotator at a rotation speed of, and rotating the rotator at a third rotation speed lower than the second rotation speed from the winning of the game ball to the specific winning opening until the specific winning opening closes, The rotating body is rotated at the first rotation speed from the time when the specific winning opening is closed.

According to the second aspect of the invention, when the game ball wins the specific winning opening being opened, the rotation control means rotates the rotating body at a third rotation speed lower than the second rotation speed, and the specific winning When the mouth is closed, the rotating body is rotated at the first rotation speed. As described above, in the present invention, when the game ball wins the specific winning opening, the rotation speed is changed to the low speed side, so that the rotating position of the special storage unit of the rotating body differs every time the specific winning opening is opened depending on the winning timing. Come. Thereby, it becomes more difficult to predict the rotational position of the special storage unit, and it is possible to further prevent a single shot of a game ball at a timing when a winning ball is stored in the special storage unit.

According to a third aspect of the present invention, in the second aspect of the present invention, the third rotation speed is lower than the first rotation speed.

According to the third aspect of the present invention, when the game ball wins the specific winning opening being opened, the rotation control means rotates the rotating body at a third rotation speed lower than the first rotation speed, and the specific winning When the mouth is closed, the rotating body is rotated at the first rotation speed. As described above, in the present invention, the rotator is rotated at a rotation speed lower than the normal rotation speed from the winning of the game ball to the specific winning opening to the closing of the specific winning opening, so that the player has a special storage unit. It becomes more difficult to take the timing of the rotational position, and it is possible to further prevent aiming. In addition, due to the shift from the high-speed rotation to the low-speed rotation, the ball biting of the game balls stored in the general storage unit and the game balls stored in the special storage unit are distributed to the path to the specific winning area during the high-speed rotation. It is possible to prevent the possibility of malfunction and prevent a malfunction.

The bottom of the turntable 63 has a turntable 63
A lower slope 73 is fitted into the lower slope 73 for housing and holding the same from the bottom surface.
75, an out hole 76 connected to a not-shown passage which is treated as a general winning, a special connection hole 77 connected to a not-shown passage leading to a special device operating area, and a motor 69 having a lower slope. 73, and a motor hole 78 for being installed in the motor 73.

A special device operation switch 67 is disposed below the special connection hole 77 (see FIG. 4). The special device operation switch 67 passes through the special connection hole 77 to reach a special device operation area. Detects a sphere and sends a detection signal to CPU3
2 The CPU 32 is a special device operation switch 6
The special device is operated or stopped based on the detection signal of (7).

On the back of the turntable 63, a specific winning device substrate 42 and a holding member 74 for holding the substrate 42 on the rear base 72 are arranged. Note that the specific winning device 3 is operated while the specific winning opening 3a is open or
5 is provided with the indicator lamps 57 and 68 of FIG.

Next, the detailed structure of the turntable 63 will be described with reference to FIG. First, a top view of the rotating disk 63 is shown in FIG.
Shown in As shown in FIG. 6 (a), the turntable 63 is provided with ten game ball storage sections provided by drilling the turntable into a semi-circular shape at predetermined angles. This one
The zero game ball storage unit includes nine general storage units 81 and one special storage unit 82 (V zone).

The general storage section 81 has a bottom surface 84 as shown in the sectional view of FIG.
The position is inclined such that the height decreases as the distance from the vehicle increases, and no obstacle is provided at the outermost edge. In addition, the special storage section 82 does not have a bottom surface, and the outflow prevention member 83 for preventing the stored game balls from flowing out from the side surface of the turntable 63 at the outermost edge of the special storage section. Is attached. Here, this rotary disc 6
FIG. 6C shows a top view of the lower slope 73 that accommodates the lower slope 3.

Next, the operation of the turntable 63 will be described with reference to FIG. As shown in FIG. 7C, a game ball that has flowed down from above while the turntable 63 is rotating in the direction of the arrow in the drawing (a game ball that has entered a specific winning opening) is stored in any of the turntables 63 Stored in the department.

As shown in the left diagram of FIG. 7A, in the game balls stored in the special storage section 82, the turntable 63 rotates in the direction of the arrow in the drawing, and the special storage section 82 faces the out hole 76. Even at the time, it does not flow out to the out hole 76 because of being blocked by the outflow prevention member 83, and as shown in the right figure of FIG. Since no bottom surface is provided, the game ball flows down to the special device operation area. FIG. 4 also shows how the game balls flow down to the special device operation area.

On the other hand, as shown in the left diagram of FIG. 7 (b), the game ball stored in the general storage unit 81 is rotated by the turntable 63 in the direction of the arrow in FIG. 76
When it faces, it flows out of the storage portion to the out hole 76 due to the inclination attached to the bottom surface, and is treated as a general prize.

Here, when one game ball enters the specific winning opening 3a, the probability that this game ball is stored in the special storage section 82 is 1/10, so that one game ball is special. There is a 1/10 chance that the device will be activated and a rights state will occur. The probability that this right state occurs will increase as the number of game balls entering the specific winning opening 3 increases, and when 10 game balls enter the ball and are stored in all the storage units, the right state always occurs. . That is, the probability that the right state will occur varies depending on the number of balls that have entered the specific winning opening 3a. Since the number of balls that can enter the specific winning opening 3a is related to the opening time of the specific winning opening 3a, the probability of the right state being generated also depends on the opening time of the specific winning opening 3a.

The processing flow of the pachinko machine having the above-described configuration will be described with reference to the flowcharts of FIGS.

As shown in the flowchart of FIG. 8, first, initial settings for setting initial values of variables used in a game are performed (step 200). The initial setting, the symbol ordinary symbol display device 2 initializes the open time T ₁ of the particular winning hole 3a, for example, about 0.8 seconds (0.795 seconds) which is opened when matching the jackpot display setting ( Normal mode setting) is also included.

When the opening time T ₁ is set to 0.8 seconds, even if a big hit occurs and the specific winning opening 3a is opened, the number of game balls that can be won is usually 1 to 1 at most.
There are three, and the probability that the right is generated even if a big hit occurs and the ball enters the specific winning opening 3a is about 1/10 to 1/3. Therefore, in combination with the pachinko machine of the probability non-variable type shown in FIG. 15A in which the jackpot occurrence probability is not increased, the jackpot occurrence probability is reduced as described above.
As compared with the probability 1/250 of the conventional stochastic pachinko machine shown in FIGS.
Can be set to As a result, the number of times of occurrence of the jackpot and the opening of the specific winning opening 3a increases, and the player's expectation of the jackpot increases.

When the initial setting is completed, a jackpot occurrence process is executed next (step 202). This big hit occurrence processing is shown in the flowchart of FIG.

According to the flowchart of FIG. 11, it is determined whether or not a game ball has entered the ordinary symbol operation gate 1 or whether there is a winning memory in the ordinary symbol operation gate 1 (step 250). . If no game ball has entered the gate and there is no memorization of a prize (step 250, negative determination), the process returns to step 250 again to wait until there is a ball. It should be noted that the prize memory of the normal symbol operation gate 1 is limited to a predetermined number (for example, four).

When a game ball enters the normal symbol operation gate 1 or when there is a winning memory (step 250, affirmative determination), the symbol of the normal symbol display 2 changes (step 2).
52). This design has started varied until the predetermined time T ₂ has elapsed, the symbol is varied (step 254 negative determination). When the predetermined time T ₂ from the symbol variable start has elapsed (step 254 affirmative determination), the normal symbol display device 2 stops the variation of symbols (Step 256). In this stopped state, the combination of symbols is determined.

Next, it is determined whether or not the stopped symbol combination is a combination corresponding to the big hit display (for example, "777") (step 258). If it is not a jackpot display (No at Step 258), Step 25
Returning to 0, the same processing as above is repeated. On the other hand, if the stopped symbol matches the jackpot display (step 25)
8 affirmative determination), the routine of the jackpot occurrence process is returned, and the next step of the flowchart of FIG. 8 is executed.

As shown in FIG. 8, when the symbol on the ordinary symbol display 2 matches the jackpot display, the specific winning device 3 opens the specific winning opening 3a (step 204). At this time,
Special equipment is activated.

Next, it is determined whether or not the winning ball detection switch 3b detects a game ball that has won the specific winning opening 3a (step 205). When a winning ball is detected (Step 205, affirmative determination), the number of winning balls from the opening of the specific winning opening 3a is cumulatively counted (Step 206), and the counted number of winning balls is counted to a specific number (for example, to the turntable 63). When the maximum number that can be stored is 10 (Step 2)
08 affirmative determination), closing the specific winning opening 3a (step 2)
11).

[0064] If the winning ball number has not reached the specified number (step 208 negative decision), it determines whether the setting of the opening time T ₁ of the particular winning hole 3a has elapsed (step 210). If the settings from the open time T ₁ is not passed (step 210 negative determination), repeats the same processing returns to step 205, if the set time T ₁ is elapsed (step 210 affirmative decision), a particular winning hole 3a Close (step 211). That is, the condition of closing a particular winning hole 3a is a either winning ball is there a or specific number set time T ₁ is passed from the open.

When the predetermined time T ₃ has elapsed since the closing of the specific winning opening 3a (Yes at step 212),
The special device is invalidated (step 213), and step 20 is executed.
2, the process is executed from the jackpot generation process. That is, a period in special apparatus is effective is up when a predetermined time T ₃ is closed is the winning port from the time of opening the particular winning hole 3a has elapsed, the rotary disc 63 which rotates constantly during this valid period When the stored game balls pass through the special device operation area, the special device operates.

Next, the processing from generation to disappearance of the right state when the game ball passes through the special device operation area during the valid period of the special device shown in the flowchart of FIG. 8 will be described with reference to the flowchart of FIG. I do.

As shown in the flowchart of FIG. 9, when the special device is valid (step 276 affirmative determination) and the game ball passes through the special device operation area (step 278 affirmative determination), the special device is activated. A right status is generated (step 280). In a state where this right has been generated, the player aims to enter the third-type starting port 5.

When the game ball again passes through the special device operation area in a state where the right has been generated (Yes at Step 281), the special device is stopped, the right state disappears (Step 292), and the process returns to Step 276. And wait for the next right.

If a game ball wins in the third type starting port 5 in a state where the right has been generated (Yes at Step 282), the special winning port 6 is opened (Step 284). The player can win a larger number of game balls by winning game balls in the special winning opening 6 than in the normal winning opening.

The opening operation of the special winning opening is continued until a predetermined time elapses after opening or until a predetermined number of winnings are made in the special winning opening (step 286, negative determination). An affirmative determination), the special winning opening 6 is closed (step 288).

Next, it is determined whether or not the number of winnings in the third type starting port 5 has reached a specific number (for example, 16) (step 290). If the winning number is less than 16 (step 29
Returning to step 281, the opening process of the special winning opening is similarly repeated. If the number of winnings reaches 16 (step 290, affirmative determination), the operation of the special device is stopped and the right status disappears (step 292), and step 2 is executed.
The process returns to step 76 to wait for the next right generation.

Next, when the game ball passes through the special device operating area during the valid period of the special device shown in the flowchart of FIG. 8, the special winning opening 3 by the opening time change symbol display 7 is displayed.
The lottery process of opening time a will be described with reference to the flowchart of FIG. This lottery process is performed in parallel with the right generation process of FIG.

As shown in the flowchart of FIG. 10, when the special device is valid (step 216 affirmative determination) and the game ball passes through the special device operation area (step 217 affirmative determination), the opening time change symbol display is displayed. The change of the symbol displayed by the container 7 is started (step 218). At this time, the opening time change symbol display 7 is "1" to "16".
Randomly display integers up to. In addition, as a method of displaying an integer at random, for example, there is a method of displaying an integer corresponding to a random number updated for each interrupt cycle.

It is determined whether or not a predetermined time T ₄ has elapsed from the start of the symbol change on the opening time change symbol display 7 (Step 220). If the predetermined time T ₄ has elapsed (Yes at Step 220), Stop the pattern change (Step 22
2), the symbols are determined.

Next, it is determined whether or not the right status has expired (step 224). If the right status has not expired (negative determination in step 224), the processing shown in the flowchart of FIG. 9 is continued. , Wait until rights expire.

When the right status has expired (step 2
24 affirmative determination), the symbol when the opening time change symbol indicator 7 is stopped is a special mode entry symbol (for example, “3”,
"5", "7") (step 2).
26). If the symbol when the opening time change symbol indicator 7 is stopped is the special mode entry symbol (step 226, affirmative determination), it is opened when the next big hit occurs (step 204 in FIG. 8). the T ₁ about 4.5 seconds (4.493 seconds; special mode) is set to.
Then, the process returns to step 216 to wait for the next special device activation time. If the special mode entry symbol is displayed when the special mode has already been set, the special mode is continued.

If a jackpot occurs in the special mode, the maximum opening time of the specific winning opening 3a is about 4.5 seconds, so that the specific winning port 3a is more specific than in the normal mode in which the opening time is set to about 0.8 seconds. The number of balls that can be awarded to the winning opening 3a increases, and the probability of generating a right is greatly improved. By being able to hit such a special mode,
Even if the opening time of the initial specific winning opening 3a is short, the player can further increase the expectation for acquiring the right.

When the symbol at the time of stopping the opening time change symbol indicator 7 is not the special mode entry symbol (step 22)
6 negative determination), it is determined whether or not a special mode end symbol (for example, “2”, “4”, “6”, “8”) (step 230). If the symbol is the special mode end symbol (step 230, affirmative determination), the specific winning opening 3
Set the opening time T ₁ of the a to about 0.8 seconds (normal mode), and waits next to during special device effectively returns to step 216. If the special mode end symbol is displayed when the normal mode has already been set,
Normal mode is continued. By providing the case in which the special mode is terminated in this way, it is possible to prevent the state in which the right state has a high probability of occurrence from continuing indefinitely,
The jackpot occurrence probability can be set to a certain level or more.

[0079] If it is not the special mode end design (step 230 negative determination), to set without changing the opening time T ₁ and returns to step 216. That is, when a symbol (“1”, “9” to “16”) that is neither the special mode entry symbol nor the special mode end symbol is displayed, the set mode is continued.

The opening time T ₁ of the specific winning opening 3a selected as described above is used in the determination in step 210 at the time of the next big hit occurrence in FIG. That is, in the special mode, the specific winning opening 3a is opened up to about 4.5 seconds, and in the normal mode, the specific winning opening 3a is opened up to about 0.8 seconds. In this manner, in the present embodiment, the opening time change symbol display device 7 each time the right to generate perform lottery open time T _1.

As described above, in the pachinko machine of the present embodiment, apart from the jackpot generation game using the ordinary symbol display 2 for opening the specific winning opening 3a, another opening time change symbol display 7 is used. Since the open time lottery game is provided, the specifications of the game are expanded, and the pleasure of the player can be increased.

Next, FIGS. 13 (a) to 13 (d) show time charts relating to the opening and closing of the specific winning opening 3a, the operation of the special device, and the disappearance of the right status.

As shown in FIGS. 13 (a) and 13 (b), the special device becomes effective at the same time when the specific winning opening 3a is opened. Particular winning hole 3a is opened by the opening time T ₁ determined according to which of the normal mode and the special mode is set, it is closed after T ₁ has elapsed. The special device is operated for a predetermined time T ₃ after the specific winning opening is closed.
(E.g. 6.996 seconds) maintaining the effective state, it becomes invalid after T ₃ has elapsed (Fig. 13 (b)).

As shown in FIG. 13 (c), when a game ball passes through the special device operation area while the special device is enabled, the special device starts operating, and further, the game ball moves into the special device operation area. The special device stops operating when passing or when 16 game balls are won in the third type starting port 5. As shown in FIG. 13D, the right state occurs (ON) and disappears (OFF) according to the operation and stoppage of the special device.

In the first embodiment, the lottery method of the opening time by the opening time change symbol display 7 is not limited to the above example. In addition, although one of the two open times T ₁ is randomly selected, three or more open times may be randomly selected.

(Second Embodiment) Next, a second embodiment will be described. Since the configuration of the pachinko machine of the second embodiment is the same as that of the first embodiment, detailed description thereof will be omitted using the same reference numerals.

However, in the second embodiment, the motor 69 for rotating the turntable 63 shown in FIG. 5 is constituted by a pulse motor whose rotation speed can be changed according to the number of steps of the input pulse signal. The CPU 32 of FIG. 2 transmits a command relating to the rotation speed to the specific winning device substrate 42 in accordance with each processing condition described later, and the specific winning device substrate 42 generates a pulse signal according to the transmitted rotation speed command. Input to the motor 69. Of course, a motor other than the pulse motor can be used as long as the rotation speed is variable according to the command.

The processing of the pachinko machine according to the second embodiment will be described with reference to the flowchart of FIG. As shown in the flowchart of FIG. 12, the opening time T of the specific winning opening 3a
A setting (setting to the normal mode) for initializing ₁ to, for example, about 0.8 seconds (0.795 seconds) is performed (step 30).
0), the rotation speed (rotation disk speed) ω of the rotation disk 63 is set to the rotation speed A (15 rotations / minute) (step 302). That is, the rotating disk 63 before the occurrence of the jackpot rotates at the rotation speed A of 15 rotations per minute. The rotation speed A is determined as a rotation speed at which the rotation position of each storage section of the rotating disk 63 can be determined.

Next, a jackpot generating process is executed (step 304). Note that the jackpot generation process is performed according to the flowchart of FIG. 11 as described above.

When the ordinary symbol on the ordinary symbol display 2 matches the jackpot display (Yes at step 258 in FIG. 11), the turntable speed ω is changed from the rotational speed A to the rotational speed B (50).
(Rotation / minute) (step 306). That is, when a big hit occurs (usually confirming the role of the symbol), the turntable 63
Rotates at a high speed of 50 B per minute. The rotation speed B is determined as a rotation speed at which the rotation position of the special storage section 82 of the rotating disk 63 cannot be determined.

Then, it waits until a predetermined time T ₅ (7.500 seconds) elapses after the occurrence of the jackpot (step 30).
8 negative decision), the predetermined time T ₅ has elapsed (Step 3
08 affirmative determination), the specific winning device 3 opens the specific winning opening 3a (step 310). At this time, the special device becomes effective.

Next, it is determined whether or not the winning ball detection switch 3b has detected a game ball that has won the specific winning opening 3a (step 312). When a winning ball is detected (Yes at Step 312), if the current turntable speed ω is the rotation speed B (Yes at Step 314), the turntable speed ω is changed from the rotation speed B to the rotation speed C (5 rotations / minute). ) (Step 316). That is, when even one ball wins the specific winning opening 3a, the turntable 63 rotates at a low rotation speed C of 5 rotations per minute. The rotation speed C is maintained until the specific winning opening is closed as described later. By shifting from the high-speed rotation to the low-speed rotation in this way, it is possible to prevent ball biting and malfunction of the device. If the game ball wins and keeps rotating at a high speed, when the ball flows out of the general storage portion 81 to the out hole 76, the ball may be caught in the edge 75 (FIG. 7) or specially connected from the special storage portion 82. Hole 77
This is because the ball may not fall. In addition, when one ball does not win the specific winning opening 3a, the turntable speed maintains the rotation speed B.

When a winning ball is detected, the specific winning opening 3
The number of winning balls from the opening of a is cumulatively counted (step 318), and when the counted number of winning balls reaches a specific number (for example, 10 which is the maximum number that can be stored in the turntable 63) (step 320). Affirmative determination), specific winning opening 3a
Is closed (step 324).

[0094] If the winning ball number has not reached the specified number (step 320 negative decision), or does not detect the winning ball (step 312 negative decision), or setting the open time T ₁ of the particular winning hole 3a has elapsed It is determined whether or not it is (step 322). If the settings from the open time T ₁ is not passed (step 322 negative determination), repeats the same processing returns to step 312, if the set time T ₁ is elapsed (step 322 affirmative decision), a particular winning hole 3a Close (step 324). That is, the condition of closing a particular winning hole 3a is a either winning ball is there a or specific number set time T ₁ is passed from the open.

When the specific winning opening 3a is closed, the turntable speed ω, which is either the rotation speed B or the rotation speed C, is changed to the rotation speed A (15 rotations / min) before the occurrence of the jackpot (step 326).

When the predetermined time T ₃ has elapsed since the closing of the specific winning opening 3a (step 328, affirmative determination),
The special device is invalidated (step 330), and step 30
4, the process is executed from the jackpot generation process. That is, a period in special apparatus is effective is up when a predetermined time T ₃ is closed is the winning port from the time of opening the particular winning hole 3a has elapsed, the rotary disc 63 which rotates constantly during this valid period When the stored game balls pass through the special device operation area, the special device operates. Note that the processing from the generation of rights to disappearance and the mode lottery processing are performed in the first embodiment (FIG. 9,
Since it is the same as FIG. 10), the description is omitted.

Next, the opening and closing of the special winning opening 3a and the turntable 6
A three-time chart of the rotation speed ω of, the normal mode and the open time extension to extension function of the opening time T ₁ is not working is divided into a special mode in operation 14
14 (a) and FIG. 14 (b).

As shown in FIG. 14A, in the normal mode, when a big hit occurs, the rotation speed ω of the turntable changes from the rotation speed A to the rotation speed B, and the specific winning opening is 7.500 seconds after the occurrence of the big hit. It is released and the release operation ends after 0.795 seconds. If one game ball wins during the opening operation of the specific winning opening, the rotation speed of the turntable changes from the rotation speed B to the rotation speed C. Then, when the specific winning opening closes, the rotation speed C returns to the original rotation speed A.

As shown in FIG. 14 (b), in the special mode, when a big hit occurs, the rotation speed ω of the rotating disk changes from the rotation speed A to the rotation speed B, and the specific winning opening is 7.500 seconds after the occurrence of the big hit. It is released and the release operation ends after 4.493 seconds. If one game ball wins during the opening operation of the specific winning opening, the rotation speed of the turntable changes from the rotation speed B to the rotation speed C. Then, when the specific winning opening closes, the rotation speed C returns to the original rotation speed A.

However, when the opening operation is completed without the game ball winning the specific winning opening in any mode, the rotation speed returns to the rotation speed A without shifting to the rotation speed C.

As described above, in the second embodiment, the rotating disk 63 is rotated at a high speed (rotational speed B = 5) from the occurrence of the jackpot until the specific winning opening 3a is opened and the winning ball is detected.
(0 rotations / minute), it is impossible for the player to predict where the position of the V zone (special storage unit 82) of the turntable 63 is. Further, when the special winning opening 3a is opened and a winning ball is detected, a low-speed rotation (rotation speed C = 5 rotations / minute) is performed. Comes to a different position each time it opens. From these points, it is possible to prevent the aiming of firing the ball at the timing when the V zone comes to the rotational position where the winning ball can be stored. For this reason, in order to ensure that the right is generated, the player must always fire the game ball while the specific winning opening is open, and the right state always occurs with an extremely small number of balls. Can be suppressed.

Note that the above effect can be achieved if the rotation speed B is set to a speed much higher than the normal rotation speed A. However, as described in the above embodiment, the player can change the rotation position of the V zone. It is preferable to set the rotation speed to about three times or more than three times the rotation speed in the range in which it can be determined. At a rotation speed A of about 15 rotations per minute as in the prior art, aiming can be performed because the rotation of the turntable 63 can be tracked by eyes, but if the rotation speed is increased to three times or more than this, the rotation can be tracked This makes it impossible to aim and strike.

The above is an example of the embodiment of the present invention, but the present invention is not limited to the above example. For example, in the present embodiment, whether or not to open the specific winning opening 3a is determined by the combination of the symbols of the ordinary symbol display 2, but the present invention is not limited to this. It may be determined whether or not the specific winning opening 3a is opened based on the establishment of a predetermined condition such as winning a product.

Further, the second embodiment can be applied to a pachinko machine other than the pachinko machine of the first embodiment.

[0105]

As described above, according to the first aspect of the present invention, the second rotation speed higher than the first rotation speed from when the predetermined condition is satisfied until the game ball wins the specific winning opening. Because the rotating body of the special winning means is rotated, the rotation position of the special storage unit provided in the rotating body can not be predicted, and the game ball is shot one shot at a time when the winning ball is stored in the special storing unit This can prevent the player from aiming to acquire the right.

According to the second aspect of the present invention, when a game ball wins a specific winning opening being opened, the rotating body is rotated at a third rotation speed lower than the second rotation speed, and the specific winning opening is closed. The rotating body is rotated at the first rotation speed when the special winning port is opened. Therefore, the rotation position of the special storage unit of the rotating body differs every time the specific winning opening is opened depending on the timing of winning the specific winning opening. Accordingly, it is possible to obtain an effect that it is more difficult to predict the rotational position of the special storage unit, and it is possible to further prevent aiming.

According to the third aspect of the present invention, when a game ball wins a specific winning opening being opened, the rotating body is rotated at the third rotation speed lower than the first rotation speed.
It becomes more difficult for the player to take the timing of the rotation position of the special storage section, which can further prevent the aiming, and the game balls stored in the general storage section and the game balls stored in the special storage section can be moved at a high speed. This has the effect of preventing the possibility of being unable to be assigned to the path to the specific winning area during rotation and preventing malfunctions before they occur.
