[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pachinko machine that generates a state that is advantageous to a player. Specifically, a specific winning opening is opened when a predetermined condition is established, and a game ball passes through a specific winning area in the specific winning opening. The present invention relates to a pachinko machine that generates a right state that is advantageous to the player.
[0002]
[Prior art]
Conventionally, in a certain type of pachinko machine, when a game ball passes through the gate in the center of the game board, a plurality of symbols displayed on the normal symbol display are changed for a predetermined time, and when the symbol is stopped, for example, 777 etc. A big hit was given when a specific combination of the symbols was displayed.
[0003]
In such a pachinko machine, a special winning device equipped with a rotating disk that always rotates at a constant low rotation speed in a state where a big hit has occurred so as to open the specific winning port (a winning port related to a normal electric accessory). Controlled. The turntable is provided with a plurality of ball storage units, and the game balls won from the specific winning opening are stored in any of the ball storage units. These ball storage units include a special storage unit (V zone) that distributes the balls stored along with the rotation of the turntable to a route to the special device operation region, and a general storage unit that processes, for example, a general prize other than the special device operation region. There is.
[0004]
When the game balls are stored in the V zone, when the turntable rotates by a predetermined angle, the stored game balls are distributed to a route to the special device operation region, and a right state that is advantageous for the player is generated. On the other hand, even if game balls are stored in the general storage unit, the stored game balls are processed as general winnings and no right state is generated. Therefore, in order to generate the right state, it is necessary to fire the game ball so that one of the game balls won in the specific winning opening is stored in the V zone. At this time, the player becomes more advantageous as the right state is acquired with as few balls as possible.
[0005]
It should be noted that the V zone and the general storage section are different in shape at first glance in order to have the above-described difference in function. For this reason, the V zone can be determined from the window provided in the specific winning device. .
[0006]
[Problems to be solved by the invention]
However, in the conventional pachinko machine described above, the rotating disk is always rotating at a constant low rotation speed, and the player can easily determine the rotational position of the V zone. The problem is that when the winning ball is not in the rotational position where the winning ball can be stored, the ball is not fired, and the so-called target hitting is possible in which the V zone is fired at the timing when the winning zone reaches the rotating position where the winning ball can be stored. Occurs.
[0007]
Such aiming is not preferable because the right state is generated with an extremely small number of balls.
[0008]
In view of the above facts, the present invention has an object to provide a pachinko machine capable of preventing a targeted hit to the V zone and generating a right state with an appropriate number of balls.
[0009]
[Means for Solving the Problems]
  In order to achieve the above object, the invention of claim 1 is characterized in that a specific winning opening is opened for a set time after a predetermined time elapses after a predetermined condition is established, and a game ball that has won a prize at the specific winning opening is specified. In a pachinko machine that generates a right state that is advantageous to the player by passing through the area, a game ball that is controlled to rotate at a first rotational speed and wins a specific winning opening until the predetermined condition is satisfied. A specific winning means including a rotating body having a general storage portion and a special storage portion for storing, and distributing only the game balls stored in the special storage portion to a path to the specific winning area; and the predetermined condition is established. The rotating body is rotated at a second rotational speed that is higher than the first rotational speed from time to time until a game ball wins the specific winning opening.The rotating body is rotated at a third rotational speed lower than the second rotational speed until the specific winning opening is closed from the winning of the game ball to the specific winning opening, and the specific winning opening is Rotating the rotating body at a first rotation speedAnd a rotation control means.
[0010]
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 since the establishment. Here, as a predetermined condition, when a game ball wins a predetermined winning opening, a plurality of symbols are variably displayed for a predetermined time, and a combination of symbols at a stop matches a predetermined display. .
[0011]
Then, the rotation control means rotates the rotating body of the specific winning means at a second rotational speed higher than the first rotational speed from when the predetermined condition is satisfied until the game ball wins the specific winning opening. In other words, the rotating body rotates at a higher speed than usual until the predetermined winning condition is established and the specific winning opening is opened and the game ball wins, so the rotation position of the special storage section provided in the rotating body cannot be predicted. In addition, it is possible to prevent aiming to acquire a right by playing a single game ball at the timing when the winning ball is stored in the special storage unit.
[0013]
  further,The rotation control means rotates the rotating body at a third rotational speed that is lower than the second rotational speed when the game ball wins the open special winning opening, and when the specific winning opening closes, the first rotation Rotate the rotating body at 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. Therefore, the rotation position of the special storage portion of the rotating body varies every time the specific winning opening is opened depending on the winning timing. Come. As a result, it becomes more difficult to predict the rotational position of the special storage unit, and it is possible to further prevent a target hitting a single game ball at the timing when the winning ball is stored in the special storage unit.
[0014]
  Claim2The invention of claim1In the invention, the third rotation speed is lower than the first rotation speed.
[0015]
  Claim2In the invention, the rotation control means rotates the rotating body at a third rotational speed lower than the first rotational speed when the game ball wins the open special winning opening, and when the specific winning opening is closed, The rotating body is rotated at the first rotation speed. As described above, in the present invention, the rotating body is rotated at a lower rotational speed than the normal rotational speed from the winning of the game ball to the specific winning opening until the specific winning opening is closed. It becomes more difficult to take the timing of the rotation position, and aiming can be further prevented. In addition, by shifting from high-speed rotation to low-speed rotation in this manner, the game balls stored in the general storage section and the game balls stored in the special storage section are distributed to the path to the specific winning area at high speed rotation. It is possible to prevent a malfunction by preventing the possibility of being lost.
In the invention of claim 3, in the invention of claim 1 or 2, the stop display is performed after changing the opening time change symbol when the game ball passes through the specific winning area, and the stop display is performed. The symbol is used to notify the next opening time of the specific winning a prize using the symbol.
[0016]

In addition, the wing member 51b is arranged such that when the specific winning opening 3a is opened from the closed position, the P in FIG.₂When turning from the open position to the closed position,₂Rotate in the 'direction.
[0037]
Next, the internal configuration of the specific winning device 3 will be described with reference to the cross-sectional view of FIG. 4 and the exploded view of FIG.
[0038]
As shown in FIGS. 4 and 5, a front slope 56 is provided between the base plate 52 and the front decoration plate 53. Further, a solenoid 58 serving as a drive source for opening and closing the wing members 51 a and 51 b is attached to the back side of the base plate 52. A shaft 62 is housed inside the cylindrical coil of the solenoid 58, and this shaft 62 is drawn into the inside by a magnetic field generated inside the solenoid when the power of the solenoid 58 is turned on. It moves by a predetermined distance in the Q direction in FIG.
[0039]
Further, a spring 59 is attached to the outer periphery of the shaft 62 outside the solenoid 58 of the shaft 62, and when the solenoid power is turned off, the shaft 62 is moved by a force in a direction in which the compressed spring 59 returns. It moves by a predetermined distance in the Q ′ direction of FIG. That is, as the solenoid 58 is turned on and off, the shaft 62 moves by a predetermined distance in the Q and Q ′ directions in FIG.
[0040]
Further, a pair of right-angled connecting arms 60 are attached to the outer end of the shaft 62 via a connecting body 62a shown in FIG. A central shaft 61 is attached to the connecting arm 60 at a portion bent at a right angle. The connecting arm 60 corresponds to the shaft 62 moving a predetermined distance in the Q and Q ′ directions in FIG. Rotate by a predetermined angle around the central axis 61 in the R and R ′ directions in FIG.
[0041]
The distal end portion of the connecting arm 60 has a substantially U-shape when viewed from the side (crank 60a), and the crank 60a protrudes perpendicularly to the base plate 52 through the hole 70 in FIG. It arrange | positions so that the interlocking | shaft axis | shaft (not shown) attached to the wing | blade member 51a, 51b which each was attached may be pinched | interposed. The hole 70 is formed in an arc shape around the shaft 71 around the mounting shaft 71 of the wing members 51a and 51b. When the connecting arm 60 rotates in the R and R ′ directions in FIG. 4 and the crank 60a moves in the vertical direction, the interlocking shaft sandwiched by the crank also rotates around the mounting shaft 71 along the hole 70, and the wing member 51a and 51b perform opening and closing movements. That is, the wing members 51a and 51b perform opening and closing operations when the solenoid 58 is turned on and off.
[0042]
Also, below the solenoid 58, a winning ball detection switch 3b for detecting a game ball that has entered the specific winning port 3a is disposed. The winning ball detection switch 3b has a passage hole through which a game ball can pass, and is arranged so that the gaming ball immediately after entering the specific winning port 3a passes through the passage hole as shown in FIG. The winning ball detection switch 3b detects light blocking or the like when the game ball passes through the passage hole, and sends a detection signal to the CPU 32 in FIG.
[0043]
Further, below the winning ball detection switch 3b, on the back side of the base plate 52, there is provided a rotating plate 63 having a plurality of storage portions for game balls that have entered from the specific winning port 3a, and the rotating plate 63 is accommodated from behind. The rear base 72 (FIG. 5) is disposed. The turntable 63 is arranged so that the game balls entered from the specific winning opening 3a are stored in any storage section of the turntable 63 (FIG. 4). The detailed configuration of the turntable 63 will be described later.
[0044]
A motor 69 as a drive source for rotating the rotating disk is disposed below the rotating disk 63, and a rotating shaft 64 of the motor is connected to the rotating shaft 80 of the rotating disk 63. The motor 69 is connected to the special prize-winning device board 42, and gives a torque for rotation to the turntable 63 via the rotary shaft 80 according to a command from the CPU 32.
[0045]
A rotating plate 65 having a narrow notch 65 a (FIG. 5) is attached on the rotating shaft 80 on the rotating plate 63, and the rotating plate 65 rotates with the rotation of the rotating plate 63. An origin detection switch 66 is attached to the rear base 72 so as to sandwich the outer edge of the rotating plate 65. When the rotating plate 63 rotates, the origin detecting switch 66 transmits light to the portion of the rotating plate 65 sandwiched by the switch. , And the light is detected by a photosensor provided in a portion facing the light irradiation unit. Here, when the outer edge other than the notch 65a crosses the origin detection switch 66 when the turntable 63 makes one rotation, the light from the switch is blocked and the notch 65a crosses the origin detection switch 66. Since the light passes through, the CPU 32 can detect whether or not the turntable 63 has made one rotation or the rotation position of the turntable 63 based on this detection signal. In the present embodiment, the turntable 63 is controlled to make one rotation.
[0046]
Further, a lower slope 73 for receiving and holding the rotating disk 63 from the bottom surface is fitted into the bottom of the rotating disk 63, and the lower slope 73 includes an edge 75 that covers the side surface of the rotating disk 63, and An out hole 76 connected to a passage (not shown) processed as a general prize, a special connection hole 77 connected to a passage (not shown) leading to the special device operating area, and a motor hole for installing the motor 69 on the lower slope 73 78.
[0047]
A special device operation switch 67 is disposed below the special connection hole 77 (see FIG. 4). The special device operation switch 67 detects a game ball passing through the special connection hole 77 and reaching the special device operation region. Then, the detection signal is transmitted to the CPU 32. The CPU 32 operates or stops the special device based on the detection signal of the special device operation switch 67.
[0048]
In addition, on the rear surface of the turntable 63, there are arranged a board for specific winning devices 42 and a holding member 74 for holding the board 42 on the rear base 72. Note that the specific winning device 3 includes the indicator lamp substrates 57 and 68 of FIG. 5 that include indicator lamps that are lit when the specific winning opening 3a is opened or when the turntable 63 is rotating.
[0049]
Next, the detailed structure of the turntable 63 will be described with reference to FIG.
First, a top view of the turntable 63 is shown in FIG. As shown in FIG. 6A, the rotating disk 63 is provided with ten game ball storage parts provided by drilling the rotating disk in a semi-circular shape at a certain angle. The ten game ball storage units are composed of nine general storage units 81 and one special storage unit 82 (V zone).
[0050]
As shown in the cross-sectional view of FIG. 6B, the general storage portion 81 has a bottom surface 84, and the bottom surface 84 is inclined such that the height decreases as the distance from the central axis 80 increases. The outermost edge is not provided with an obstacle. Further, the special storage portion 82 is not provided with a bottom surface, and an outflow prevention member 83 for preventing the game balls stored at the outermost edge of the special storage portion from flowing out from the side surface of the turntable 63. Is attached. Here, a top view of the lower slope 73 that accommodates the turntable 63 is shown in FIG.
[0051]
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 with the rotating plate 63 rotated in the direction of the arrow in FIG. It is stored in the part.
[0052]
As shown in the left diagram of FIG. 7A, the game balls stored in the special storage portion 82 flow out even when the rotating disk 63 rotates in the direction of the arrow in the drawing and the special storage portion 82 faces the out hole 76. When the special storage part 82 reaches directly above the special connection hole 77 as shown in the right figure of FIG. Because it is not, the game ball flows down to the special device operating area. FIG. 4 also shows the game ball flowing down to the special device operating area.
[0053]
On the other hand, as shown in the left diagram of FIG. 7B, the game ball stored in the general storage portion 81 is rotated so that the rotating disk 63 rotates in the direction of the arrow in the drawing so that the general storage portion 81 faces the out hole 76. At that time, due to the slope attached to the bottom surface, it flows out from the storage portion to the out hole 76 and is processed as a general prize.
[0054]
Here, when one game ball enters the specific winning opening 3a, the probability that the game ball is stored in the special storage unit 82 is 1/10, so the special device is activated by one ball. Thus, the probability that the right state occurs is 1/10. The probability that this right state occurs increases as the number of game balls entering the specific winning opening 3 increases, and a right state is always generated when ten game balls enter and are stored in all the storage units. . That is, the probability that the right state is generated varies depending on the number of balls that have entered the specific winning opening 3a. In addition, since the number of balls that can be entered into the specific winning opening 3a is related to the opening time of the specific winning opening 3a, the probability that the right state occurs also depends on the opening time of the specific winning opening 3a.
[0055]
The processing flow of the pachinko machine having the above-described configuration will be described with reference to the flowcharts of FIGS.
[0056]
As shown in the flowchart of FIG. 8, first, initial setting for setting initial values of variables used in the game is performed (step 200). In this initial setting, the opening time T of the specific winning opening 3a that is opened when the symbol of the normal symbol indicator 2 matches the jackpot display.₁For example, a setting (initial mode setting) for initializing to about 0.8 seconds (0.795 seconds) is also included.
[0057]
The opening time T₁Is set to 0.8 seconds, even if a big win occurs and the specific winning opening 3a is opened, the number of game balls that can be won is normally 1 to 3, and a big win occurs. The probability that a right is generated even if the player enters the specific winning opening 3a is about 1/10 to 1/3. For this reason, the probability of jackpot occurrence is shown in FIGS. 15 (b) and 15 (c) as described above, coupled with the probability non-variable pachinko machine of FIG. 15 (a) that does not increase the probability of jackpot occurrence. Compared with the probability 1/250 of the conventional probability fluctuation type pachinko machine, it can be set to 1/23 which is about 10 times that. As a result, the number of times that the jackpot is generated and the specific winning opening 3a is opened increases, and the player's sense of expectation for the jackpot is increased.
[0058]
When the initial setting is completed, a jackpot generation process is executed (step 202). This jackpot generation process is shown in the flowchart of FIG.
[0059]
According to the flowchart of FIG. 11, it is determined whether or not a game ball has entered the normal symbol operating gate 1 or whether or not there is a winning memory in the normal symbol operating gate 1 (step 250). If there is no game ball entering the gate and there is no winning memory (No at step 250), the process returns to step 250 and waits until there is a ball. In addition, the prize memory of the normal symbol operation gate 1 is limited to a predetermined number (for example, four).
[0060]
When a game ball enters the normal symbol operation gate 1 or there is a winning memory (step 250 affirmative determination), the symbol of the normal symbol display 2 changes (step 252). The predetermined time T after this symbol starts to fluctuate₂Until this time elapses, this symbol fluctuates (step 254 negative determination). And, a predetermined time T from the start of symbol variation₂Has passed (step 254 affirmative determination), the normal symbol display 2 stops the variation of the symbol (step 256). In this stopped state, the combination of symbols is determined.
[0061]
Next, it is determined whether or not the stopped combination of symbols is a combination corresponding to the jackpot display (for example, “777”) (step 258). If it is not a big win display (NO determination at step 258), the process returns to step 250 and the same processing as described above is repeated. On the other hand, if the stopped symbol matches the jackpot display (step 258 affirmative determination), the routine for the jackpot generation process is returned, and the next step of the flowchart of FIG. 8 is executed.
[0062]
As shown in FIG. 8, when the symbol on the normal symbol display 2 matches the jackpot display, the specific winning device 3 opens the specific winning opening 3a (step 204). At this time, the special device becomes effective.
[0063]
Next, it is determined whether or not the winning ball detection switch 3b has detected a gaming ball that has won the specific winning opening 3a (step 205). When a winning ball is detected (Yes at step 205), the number of winning balls from the opening of the specific winning port 3a is cumulatively counted (step 206), and the counted number of winning balls is a specific number (for example, on the turntable 63). When the maximum number that can be stored (10) is reached (Yes at Step 208), the specific winning opening 3a is closed (Step 211).
[0064]
When the number of winning balls has not reached the specific number (No at Step 208), the set time T from the opening of the specific winning port 3a is reached.₁It is determined whether or not elapses (step 210). Set time T from opening₁Has not elapsed (No at Step 210), the process returns to Step 205 to repeat the same processing, and the set time T₁When the time elapses (step 210: affirmative determination), the specific winning opening 3a is closed (step 211). That is, the condition for closing the specific winning opening 3a is that the set time T from the opening₁Either has passed or there has been a specific number of winning balls.
[0065]
Then, after the specific winning opening 3a is closed, a predetermined time T_Three(Step 212, affirmative determination) invalidates the special device (step 213), returns to step 202, and executes the processing from the jackpot generation process. In other words, the period during which the special device is valid is a predetermined time T after the winning opening is closed from when the specific winning opening 3a is opened._ThreeWhen the game ball stored in the rotating disk 63 that constantly rotates within the effective period passes through the special device operation region, the special device is activated.
[0066]
Next, the process from the generation of the right state to the disappearance 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.
[0067]
As shown in the flowchart of FIG. 9, when the special device is valid (step 276 affirmative determination), when the game ball passes through the special device operation area (step 278 affirmative determination), the special device is activated and the right state is activated. Occurs (step 280). In a state where this right is generated, the player aims to enter the third type starting port 5.
[0068]
If the game ball passes again through the special device operation area in the state where the right has been generated (step 281 affirmative determination), the operation of the special device is stopped and the right state disappears (step 292), and the process returns to step 276 to return Wait until the right is generated.
[0069]
When a game ball wins the third type starting port 5 with the right generated (step 282 affirmative determination), the big winning port 6 is opened (step 284). The player can obtain a larger number of game balls than winning in the normal winning opening by winning the gaming balls in the big winning opening 6.
[0070]
The opening operation of the grand prize opening is continued until a predetermined time has elapsed from the opening or until a predetermined number of prizes are won (step 286 negative determination), and when the predetermined time has elapsed or the predetermined number has been won (step 286 affirmative determination). Then, the special winning opening 6 is closed (step 288).
[0071]
Next, it is determined whether or not the number of winnings at the third type starting port 5 has reached a specific number (for example, 16) (step 290). If the number of winnings is less than 16 (No at step 290), the process returns to step 281 and repeats the opening process of the big winning opening. When the number of winnings reaches 16 (Yes in Step 290), the special device is stopped and the right state disappears (Step 292), and the process returns to Step 276 and waits until the next right generation.
[0072]
Next, the lottery process of the opening time of the specific winning opening 3a by the opening time changing symbol display 7 when the game ball passes through the special device operating area during the effective period of the special device shown in the flowchart of FIG. It demonstrates using the flowchart of these. The lottery process is performed in parallel with the right generation process of FIG.
[0073]
As shown in the flowchart of FIG. 10, when the special device is valid (Yes in Step 216), when the game ball passes through the special device operation area (Yes in Step 217), the opening time change symbol display 7 is The change of the displayed symbol is started (step 218). At this time, the open time changing symbol display 7 randomly displays an integer from “1” to “16”. 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 every interrupt cycle.
[0074]
A predetermined time T from the start of symbol variation on the symbol display 7 for changing the opening time_Four(Step 220) and a predetermined time T_FourWhen the time elapses (step 220 affirmative determination), the symbol variation is stopped (step 222), and the symbol is fixed.
[0075]
Next, it is determined whether or not the right state has disappeared (step 224). If the right state has not disappeared (step 224 negative determination), the processing shown in the flowchart of FIG. Wait until it disappears.
[0076]
If the right state has disappeared (Yes in step 224), whether or not the symbol when the opening time change symbol display 7 is stopped is the special mode entry symbol (for example, “3”, “5”, “7”). Is determined (step 226). If the symbol when the opening time change symbol display 7 is stopped is the special mode entry symbol (step 226 affirmative determination), the symbol is released when the next jackpot occurs (step 204 in FIG. 8). T₁Is set to approximately 4.5 seconds (4.493 seconds; special mode). Then, the process returns to step 216 to wait for the next special device valid time. If the special mode entry symbol is displayed when the special mode has already been set, the special mode is continued.
[0077]
When a big hit occurs in the special mode, the opening time of the specific winning opening 3a is about 4.5 seconds at the maximum, so that the specific winning opening 3a is compared with the normal mode in which the opening time is set to about 0.8 seconds. The number of balls that can be won is increased and the probability that a right is generated is greatly improved. Since there is a possibility of hitting such a special mode, the player can further increase his expectation for right acquisition even if the opening time of the initial specific winning opening 3a is short.
[0078]
When the symbol when the opening time change symbol display 7 is stopped is not the special mode entry symbol (No determination at step 226), it is a special mode end symbol (for example, “2”, “4”, “6”, “8”). Whether or not (step 230). If it is a special mode end symbol (step 230 affirmative determination), the opening time T of the specific winning opening 3a₁Is set to about 0.8 seconds (normal mode), and the process returns to step 216 to wait for the next special device valid time. When the special mode end symbol is displayed when the normal mode has already been set, the normal mode is continued. By providing the case where the special mode is terminated in this way, it is possible to suppress the state where the probability of occurrence of the right state is high indefinitely and set the jackpot occurrence probability to a certain level or more. .
[0079]
If it is not the special mode end symbol (No at step 230), the opening time T₁The process returns to step 216 without changing the setting. 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.
[0080]
Opening time T of the specific winning opening 3a selected as above₁Is used in the determination in step 210 when the next jackpot occurs in FIG. That is, in the special mode, the specific winning opening 3a is opened for a maximum of about 4.5 seconds, and in the normal mode, the specific winning opening 3a is opened for a maximum of about 0.8 seconds. Thus, in this embodiment, every time a right is generated, the opening time change symbol display 7 displays the opening time T.₁The lottery is performed.
[0081]
As described above, in the pachinko machine according to the present embodiment, in addition to the big hit occurrence game by the normal symbol display 2 for opening the specific winning opening 3a, the opening time of another opening time changing symbol display 7 is set. Since the lottery game is provided, the specifications of the game are expanded and the enjoyment of the player can be increased.
[0082]
Next, FIGS. 13A to 13D show time charts related to the opening / closing of the special winning opening 3a, the operation of the special device, and the occurrence and disappearance of the right state.
[0083]
As shown in FIGS. 13 (a) and 13 (b), the special device becomes effective at the same time as the specific winning opening 3a is opened. The specific winning opening 3a has an opening time T determined according to whether the normal mode or the special mode is set.₁Only open, T₁Closed after elapse. The special device has a predetermined time T after the specific prize opening is closed._Three(For example, 6.96 seconds) remains valid and T_ThreeIt becomes invalid after the elapse (FIG. 13B).
[0084]
As shown in FIG. 13 (c), if the game ball passes through the special device operation area while the special device is activated, the special device starts to operate, and whether the game ball passes through the special device operation area. Alternatively, the special device stops operating when 16 game balls win the 3rd type starting port 5. Note that, as shown in FIG. 13D, the right state is generated (ON) and extinguished (OFF) in accordance with the operation and stop of the special device.
[0085]
In addition, in 1st Embodiment, the lottery method of the open time by the open time change symbol display 7 is not limited to the said example. Two open times T₁However, it is possible to draw three or more open times.
[0086]
(Second Embodiment)
Next, a second embodiment will be described. In addition, since the structure of the pachinko machine of 2nd Embodiment is the same as that of 1st Embodiment, detailed description is abbreviate | omitted using the same code | symbol.
[0087]
However, in the second embodiment, the motor 69 that rotates the turntable 63 of FIG. 5 is configured by a pulse motor that can change the rotation speed according to the number of steps of the input pulse signal. The CPU 32 in FIG. 2 transmits a command related to the rotational speed to the specific winning device board 42 according to each processing condition described later, and the specific winning device board 42 generates a pulse signal corresponding to the transmitted rotational speed command. Input to the motor 69. Of course, if the rotational speed is variable according to the command, it is possible to configure the motor with a motor other than the pulse motor.
[0088]
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 3a₁Is set to, for example, about 0.8 seconds (0.795 seconds) (setting to the normal mode) (step 300), and the rotational speed (rotary disk speed) ω of the rotary disk 63 is set to the rotational speed A (15 Minutes) (step 302). That is, the turntable 63 before the big hit is rotated at the rotation speed A of 15 rotations per minute. The rotational speed A is determined as a rotational speed at which the rotational position of each storage section of the turntable 63 can be determined.
[0089]
Next, a jackpot generation process is executed (step 304). This jackpot generation process is performed according to the flowchart of FIG. 11 as described above.
[0090]
When the normal symbol on the normal symbol display 2 matches the jackpot display (step 258 affirmative determination in FIG. 11), the rotating disk speed ω is changed from the rotational speed A to the rotational speed B (50 rotations / minute) (step 306). In other words, when a big hit occurs (normal symbol confirmation), the turntable 63 rotates at a high rotational speed B of 50 rotations per minute. The rotational speed B is determined as a rotational speed at which the rotational position of the special storage section 82 of the rotating disk 63 cannot be determined.
[0091]
Then, a predetermined time T after the jackpot is generated_Five(7.500 seconds) waits for the elapse of time (No at Step 308) and a predetermined time T_FiveAfter the elapse of time (step 308, affirmative determination), the specific winning device 3 opens the specific winning port 3a (step 310). At this time, the special device becomes effective.
[0092]
Next, it is determined whether or not the winning ball detection switch 3b has detected a gaming ball that has won the specific winning opening 3a (step 312). When a winning ball is detected (step 312 affirmative determination), if the current rotating disk speed ω is the rotation speed B (step 314 affirmative determination), the rotation disk 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 rotating disk 63 rotates at a low rotation speed C of 5 rotations per minute. This rotational speed C is maintained until the specific winning opening is closed as will be described later. Thus, by shifting from high speed rotation to low speed rotation, it is possible to prevent ball biting and malfunction of the apparatus. If a game ball is won and remains at high speed, the ball may be caught in the edge 75 (FIG. 7) when the ball flows out from the general storage portion 81 to the out hole 76, or the special storage portion 82 may be specially connected. This is because the ball may not fall into the hole 77. In addition, when one ball does not win the specific winning opening 3a, the rotating disk speed maintains the rotation speed B.
[0093]
When a winning ball is detected, the number of winning balls from the opening of the specific winning opening 3a is cumulatively counted (step 318), and the counted number of winning balls is a specific number (for example, the maximum number that can be stored in the turntable 63). If it has reached 10 (step 320 affirmative determination), the specific winning opening 3a is closed (step 324).
[0094]
When the number of winning balls has not reached the specific number (step 320 negative determination) or when no winning ball is detected (step 312 negative determination), the set time T from the opening of the specific winning opening 3a.₁It is determined whether or not elapses (step 322). Set time T from opening₁Has not elapsed (No at step 322), the process returns to step 312 to repeat the same processing, and the set time T₁When the time elapses (step 322 affirmative determination), the specific winning opening 3a is closed (step 324). That is, the condition for closing the specific winning opening 3a is that the set time T from the opening₁Either has passed or there has been a specific number of winning balls.
[0095]
When the specific winning opening 3a is closed, either the rotation speed B or the rotation speed C is changed to the rotation speed A (15 rotations / minute) before the big hit (step 326).
[0096]
Then, after the specific winning opening 3a is closed, a predetermined time T_Three(Step 328 affirmative determination), the special device is invalidated (step 330), and the process returns to step 304 to execute the process from the jackpot generation process. In other words, the period during which the special device is valid is a predetermined time T after the winning opening is closed from when the specific winning opening 3a is opened._ThreeWhen the game ball stored in the rotating disk 63 that constantly rotates within the effective period passes through the special device operation region, the special device is activated. Note that the process from right generation to extinction and the mode lottery process are the same as those in the first embodiment (FIGS. 9 and 10), and thus the description thereof is omitted.
[0097]
Next, a time chart of the opening / closing of the specific winning opening 3a and the rotational speed ω of the turntable 63 is shown as an opening time T₁14 (a) and 14 (b), respectively, are divided into a normal mode in which the extension function is not activated and a special mode in which the open time extension function is activated.
[0098]
As shown in FIG. 14 (a), in the normal mode, the rotation speed ω of the rotating disk changes from the rotation speed A to the rotation speed B when the big hit occurs, and the specific winning opening is opened after 7.500 seconds from the occurrence of the big hit, The release operation ends after 0.795 seconds. If one game ball wins during the opening operation of the specific winning opening, the rotating disk changes from the rotational speed B to the rotational speed C. Then, when the specific winning opening is closed, the rotational speed C returns to the original rotational speed A.
[0099]
As shown in FIG. 14B, in the special mode, the rotation speed ω of the rotating disk changes from the rotation speed A to the rotation speed B when the big hit occurs, and the specific winning opening is opened after 7.500 seconds from the occurrence of the big hit, Release operation ends after 4.493 seconds. If one game ball wins during the opening operation of the specific winning opening, the rotating disk changes from the rotational speed B to the rotational speed C. Then, when the specific winning opening is closed, the rotational speed C returns to the original rotational speed A.
[0100]
However, in any mode, when the release operation is terminated without the game ball winning a specific winning opening, the speed returns to the rotational speed A without shifting to the rotational speed C.
[0101]
As described above, in the second embodiment, the rotating disk 63 is rotated at a high speed (rotational speed B = 50 rotations / minute) from when the big hit occurs until the specific winning opening 3a is opened and a winning ball is detected. Therefore, 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 winning ball 3a is opened and a winning ball is detected, the ball is rotated at a low speed (rotational speed C = 5 rotations / minute), so that the position of the V zone in the turntable 63 is determined according to the winning timing of the game ball. Each time is opened, it will be in a different position. From these points, it is possible to prevent a target shot in which a ball is fired at the timing when the V zone comes to a rotational position where a 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 prize opening is open, and the right state always occurs with an extremely small number of balls. Can be suppressed.
[0102]
The above effect can be achieved if the rotation speed B is set to be significantly higher than the normal rotation speed A. However, as shown in the above embodiment, the player can determine the rotation position of the V zone. It is preferable to set the rotational speed within the range to about 3 times or more than 3 times. At a rotational speed A of about 15 revolutions per minute as in the prior art, the rotation of the turntable 63 can be followed with the eyes, so that it is possible to hit the target. However, if the rotational speed is increased to three times or more, the eyes are followed. It becomes impossible to aim and hit.
[0103]
The above is one example of the embodiment of the present invention, but is not limited to the above example. For example, in the present embodiment, it is determined whether or not to open the specific winning opening 3a by the combination of the symbols of the normal symbol display 2. However, the present invention is not limited to this, for example, a role such as a tulip or the like. It may be determined whether or not to open the specific winning opening 3a when a predetermined condition is satisfied, such as winning a prize.
[0104]
In addition, the second embodiment can be applied to a pachinko machine other than the pachinko machine of the first embodiment.
[0105]
【The invention's effect】
As described above, according to the first aspect of the present invention, the specific winning means is operated at the second rotational speed higher than the first rotational speed from when the predetermined condition is satisfied until the game ball is won to the specific winning opening. Since the rotating body is rotated, the rotation position of the special storage unit provided in the rotating body can no longer be predicted, and the right to acquire the right by playing a single game ball at the timing when the winning ball is stored in the special storage unit The effect that the hitting to prevent can be prevented.
[0106]
According to the invention of claim 2, when the game ball wins the open specific winning opening, the rotating body is rotated at the third rotation speed lower than the second rotation speed, and the specific winning opening is closed. Since the rotating body is rotated at the first rotational speed, the rotation position of the special storage portion of the rotating body is different each time the specific winning opening is opened depending on the timing of winning the special winning opening. The effect that prediction of the rotation position of the storage part becomes more difficult and aiming can be further prevented can be obtained.
[0107]
According to the third aspect of the present invention, when the game ball wins the open special winning opening, the rotating body is rotated at the third rotational speed lower than the first rotational speed. The timing of the rotation position of the storage section becomes even more difficult, and it is possible to further prevent aiming, and at the same time, the game balls stored in the general storage section and the game balls stored in the special storage section are awarded a specific prize There is an effect that it is possible to prevent malfunctions by preventing the possibility of being routed to the route to the region.
