A special symbol display device, which is provided on the back side mechanism and has a special symbol variably displayed, is provided in a pachinko machine in which a large hit occurs when a large hit symbol is fixedly displayed by the special symbol display device. In front of the lower part of the special symbol display device, a pair of horizontally long rollers whose both ends are rotatably fixed are arranged in front and rear with their peripheral surfaces facing each other, and between the upper surfaces of the rollers. Is formed with a recessed portion capable of holding a game ball, and the rotating shaft of each roller is connected to a drive shaft of a motor via a transmission mechanism, so that the game state is a predetermined game state. A mechanism is provided for switching the rotation direction of the front roller of each of the rollers in the event that the front roller is rotated rearward while the rear roller is rotated forward. A technical means is used in which the game balls are held in a forward direction, and the respective rollers rotate forward to cause the held game balls to flow downward through the upper surface of the front roller.

  According to the second aspect of the present invention, in the pachinko machine according to the first aspect, when the special symbol display device displays the special symbol in a variable manner, a first-class start port provided on the game board wins. Storage means for storing a special symbol start storage number that is the number of game balls that have been set, and the special symbol display device has the same number of times as the special symbol start storage number stored in the storage means. The first type opening is provided in a flowing direction of a game ball flowing forward through the upper surface of the front roller, and the special symbol stored in the storage means is provided. When the starting memory number is a predetermined number, the front roller rotates backward and the rear roller rotates forward, and when the special symbol starting memory number is less than the predetermined number, the front roller Roller and said Side of the roller together using technical means that rotates forward.

  According to the third aspect of the present invention, in the pachinko machine according to the first or second aspect, the special symbol other than the special symbol stopped last is stopped in line with the same special symbol, and the special symbol stopped last is selected. When the stop pattern of the reach indicating the state of the variable display is selected from a plurality of stop patterns of the special symbol, the front roller rotates backward and the rear roller rotates forward. Technical means are used.

  According to a fourth aspect of the present invention, in the pachinko machine according to any one of the first to third aspects, the variable winning device that opens a big winning port when the big hit occurs includes the front roller. A technical means is provided in the flowing direction of the game ball flowing forward through the upper surface of the game ball.

  According to a fifth aspect of the present invention, in the pachinko machine according to the fourth aspect, the special winning opening is opened after a predetermined time has passed since the big hit symbol is fixedly displayed, and the special symbol change display is displayed. When the predetermined time elapses after stopping, the technical means that both the front roller and the rear roller rotate forward is used.

(Effect of the invention according to claim 1)
By switching the direction of rotation of the front roller when the game state becomes a predetermined game state, it is possible to hold the game ball or to flow down the held game ball.
Therefore, unlike the conventional game machine, there is no danger that the game will be monotonous unlike a pachinko machine in which the distribution member continuously performs a constant operation during the game.

(Effect of the invention according to claim 2)
When the special symbol start storage number is a predetermined number, the front roller rotates backward and the rear roller rotates forward, so that it is difficult to generate an extra game ball that wins the first type start port. be able to. When the number of special symbol start memories is less than the predetermined number, the front roller and the rear roller both rotate forward, so that the game balls held by the falling part flow down and the first kind of start is performed. Winning a prize can increase the number of special symbol starting memories.
For this reason, even if the number of special symbol start storages is, for example, the upper limit number, the player fires a game ball and tries to return the special symbol start storage number to the upper limit number again.
Therefore, unlike the related art, when the special symbol start storage number is the upper limit number, it is less likely that the player interrupts the firing of the game ball and tries to avoid wasteful consumption of the game ball. be able to.

(Effect of the invention according to claim 3)
If the stop pattern of the reach is selected as the stop pattern of the special symbol, that is, if the probability of occurrence of a big hit is high from the viewpoint of the player, the roller on the front side rotates rearward, and the game ball can be held in the lowered part. Therefore, when a big hit occurs and a special winning opening is opened, a large number of game balls are caused to flow down from the depressed portion and to win the special winning opening, even while the special symbol is displayed fluctuating. Fire a game ball.
Therefore, unlike the related art, it is possible to prevent a situation in which the emission of the game balls is interrupted until the special symbol is stopped to avoid wasteful consumption of the game balls.
In addition, the occurrence of the reach can be predicted by changing the rotation direction of the front roller that has been rotating forward to the rear.

(Effect of the invention according to claim 4)
Since the variable winning device that opens the big winning opening when a big hit occurs is provided in the flowing direction of the game ball that flows forward through the upper surface of the front roller, there are many game balls that flow down from the falling part. Thus, the number of game balls that win the large winning opening can be increased.

(Effect of the invention according to claim 5)
When a predetermined time elapses after the special symbol change display stops, both the front roller and the rear roller rotate forward, so that the game ball held in the depressed portion is placed in the opening of the special winning opening. You can also win a prize by flowing down.

Next, a main flow of the game will be described with reference to FIGS.
FIG. 5 is a flowchart showing the flow of the first type start-up process executed by the main CPU 112. FIG. 6 is a flowchart showing the flow of the special symbol display process executed by the main CPU 112. FIG. 7 is a flowchart illustrating a flow of the roller control executed by the main CPU 112.

(Type 1 starting port processing)
First, the flow of the first type start-up process will be described with reference to FIG.
When the game ball passes through the first-type starting port 27 (FIG. 2) or through the open ordinary electric accessory 28 (FIG. 2) and the first-type starting port switch 27a (FIG. 4) is turned on, the main CPU 112 Detects that the first-type start-up switch 27a is turned on by detecting a voltage change of the input port connected to the first-type start-up switch 27a (S10: Yes). Subsequently, when the special symbol start storage number U1 is less than “4” (S12: Yes), the main CPU 112 adds “1” to the special symbol start storage number U1 (S14), and counts the big hit value. One count value of the counter is obtained (S16), and the obtained count value is temporarily stored in the RAM 116 (S18). For example, the jackpot counter counts a total of 256 values from 0 to 255.

(Special symbol display processing)
Next, the flow of the special symbol display process will be described with reference to FIG.
The main CPU 112 determines whether or not a control command for changing and displaying the special symbol is output to the special symbol display device 32, that is, whether or not the special symbol is changing, and if it is determined that the special symbol is not changing ( S30: No), it is determined whether or not the special symbol start storage number U1 is "1" or more (S32). Subsequently, when determining that the special symbol start storage number U1 is equal to or more than "1" (S32: Yes), the main CPU 112 subtracts "1" from the special symbol start storage number U1 (S34). Subsequently, the main CPU 112 reads the count value temporarily stored in the RAM 116 in S18 (FIG. 5) of the first-type start-up process (S36), and determines whether or not the read count value matches the big hit value, ie, It is determined whether it is a big hit (S38).

Subsequently, when it is determined that the jackpot is a big hit (S38: Yes), the main CPU 112 randomly selects one set of the big hit symbols from the big hit symbol table set by associating each of the plurality of random numbers with the big hit symbols (S40). ). For example, if the big hit symbol table is set so that the random numbers “0” to “9” are associated with the big hit symbols “000” to “999”, and a random number “7” is selected, The symbol "777" is selected.
Further, when the main CPU 112 determines that it is not a big hit, that is, a loss (S38: No), the main CPU 112 sets a plurality of random numbers and a loss symbol as a loss symbol for a left stop symbol from a loss symbol table set in association with each other. One loss symbol is randomly selected, and similarly, the loss symbols for the middle symbol and the right stop symbol are each selected without care (S42). For example, when the loss symbol table is set so that the random numbers “0” to “9” are associated with the loss symbols “0” to “9”, if the random number “2” is selected, Select the symbol "2".

  Next, the main CPU 112 selects one stop pattern from a stop pattern table in which a plurality of random numbers are associated with a plurality of stop patterns of a special symbol (S44). For example, the relationship between the random number set in the stop pattern table and the stop pattern is individually set for the case of a big hit and the case of a loss, and the relationship for the big hit is a random number “0” and a normal stop, When the random numbers "1" to "6" and the long reach and the random numbers "7" to "15" are the special reach and the random number "7" is selected, the special reach is determined as the stop pattern. The reach means a state in which symbols other than the symbol that stops last stop together with the same symbol, and the symbol that stops last is variably displayed. In other words, it means a state one step before the big hit. In addition, the probability of a big hit in the order of normal stop, long reach, and special reach is increased, and the effect contents at the time of stop are elaborate.

  Subsequently, the main CPU 112 transmits a change start command for instructing the start of the change display of the special symbol to the special symbol display device 32 (S46). Thereby, the special symbol display device 32 starts the variable display of the left symbol, the middle symbol, and the right symbol. Subsequently, the main CPU 112 resets a stop flag indicating that the variable display of all symbols has stopped (S48), and determines whether the stop pattern selected in S44 is a reach pattern (S50). Here, if it is the reach pattern (S50: Yes), the reach pattern flag indicating that the reach pattern has been selected is set (S52). The determination result as to whether or not the reach pattern flag is set is used in roller control described later.

If the main CPU 112 determines that the fluctuation time of all the symbols has elapsed (S54: Yes), the main CPU 112 performs a special symbol stop process according to the stop pattern selected in S44 (S56). In the stop processing, for example, when it is time to stop the left symbol, a left symbol stop command and a left symbol designation command are transmitted to the special symbol display device 32 to stop the left symbol and display the left stopped symbol. . Similarly, stop and stop symbols are displayed for the middle symbol and the right symbol. In the case of the reach pattern, an effect screen peculiar to reach is displayed and the last symbol is stopped.
Subsequently, the main CPU 112 sets a stop flag indicating that the variable display of all symbols has stopped, resets the reach flag (S58), and ends the current routine of the special symbol display process.

(Roller control)
Next, the flow of roller control will be described with reference to FIG.
The main CPU 112 determines whether or not the special symbol start storage number U1 is “4” (S60), and if it is “4” (S60: Yes), issues a command to the mechanism for switching the rotation direction of the roller 97. Then, the rotation direction of the roller 97 disposed on the front side is switched backward (S62). As a result, as shown in FIG. 3A, the roller 97 rotates backward and the roller 98 rotates forward, and the game balls P flowing down from the flow-down passage 96a to the guide portion 96b are transferred to the rollers 97 and 98. Is held at the depression V formed on the upper surface of the. Note that, when the number of game balls held in the depressed portion V exceeds the number that can be held, the excess game balls flow down without being held.
When determining that the special symbol start storage number U1 is not “4” (S60: No), the main CPU 112 switches the rotation direction of the roller 97 forward (S64). As a result, as shown in FIG. 3 (B), the rollers 97 and 98 are both rotated forward, and the game ball P held at the fall portion V is released from the hold, and is placed on the front side. The roller 97 rolls on the upper surface of the roller 97 and flows down in the direction (forward) indicated by F5 in the figure. Therefore, the dropped game balls P can be awarded to the first type starting port 27 provided below the center case 30 (FIG. 2) or the ordinary electric accessory 28 with both wings opened.

That is, when the special symbol start storage number U1 is "4", even if the game ball further wins the first type start port 27 or the opened ordinary electric accessory 28, the special symbol start storage number U1 is obtained. Cannot exceed “4”, during which the player can shoot a game ball and hold the shot game ball in a dip V formed on the upper surfaces of the rollers 97 and 98. After that, when the special symbol change display is started, the special symbol start storage number U1 is subtracted by “1” in S34 of the special symbol display process and becomes “3”, so that the rotation direction of the roller 97 is changed from the rear. When the game ball P, which has been switched to the front and held in the depressed portion V, wins the first type starting port 27 or the ordinary electric accessory 28 with both wings opened, the special symbol starting storage number U1 is again changed to " 4 ". At this time, since the first-type starting port 27 and the ordinary electric accessory 28 are provided directly below the rollers 97 and 98, the game balls P flowing forward from the upper surface of the roller 97 can be transferred to the first-type starting port with a high probability. 27 or an ordinary electric accessory 28 with both wings open.
Therefore, after the special symbol start storage number U1 becomes “4”, it is possible to prevent a situation in which the player interrupts the firing of the game ball.
If the special symbol start storage number U1 becomes "4" while playing a game with a big hit, the front roller 97 rotates backward, so that the game ball is held in the depressed portion V, and the holding is performed. When the number of game balls being held exceeds the number that can be held, the excess game balls flow down without being held. Then, the game due to the big hit ends, the first special symbol change display is started, and when the special symbol start storage number U1 becomes “3”, the front roller 97 rotates forward, so that it is held in the dip portion V. The dropped game balls flow down at once, the dropped game balls enter the first-type starting port 27, and the special symbol starting storage number U1 increases to “4” again.

Subsequently, the main CPU 112 determines whether or not the reach flag is set in S52 of the above-described special symbol display processing (S66). If the reach flag is set (S66: Yes), the rotation direction of the roller 97 is set backward. (S68). As a result, the game balls P flowing down to the upper portions of the rollers 97 and 98 are held at the fall portion V.
Subsequently, the main CPU 112 determines whether or not the stop flag is set in S58 of the special symbol display process (S70). If the stop flag is set (S70: Yes), the variable display of all symbols is stopped. It is determined whether or not the elapsed time T from the time has become equal to or longer than t1 (S72). The time t1 is the time required from the stop of the variable display of all the symbols to the opening of the special winning opening 41 in the case of a big hit.

Here, if the elapsed time T is equal to or longer than the time t1 (S72: Yes), the rotation direction of the roller 97 is switched forward (S74). As a result, the game ball P held at the falling portion V rolls on the upper surface of the roller 97 and flows forward.
Therefore, when the special winning opening 41 is open at the big hit, the dropped gaming ball P can enter the special winning opening 41 opened below the center case 30 (FIG. 2). At this time, as the number of the game balls P suspended in the falling portion V increases, the number of the game balls P rolling from the upper surface of the roller 97 and flowing forward increases, and therefore, of the game balls P flowing down, the special winning opening The number of gaming balls P that wins 41 increases.

As described above, when the reach pattern is selected, the roller 97 is rotated backward, and the roller 97 is rotated forward at the timing when the special winning opening 41 is opened. Since the player can cause P to flow down, the player fires the game ball while the special symbol is displayed in a fluctuating manner so as to make as many game balls P as possible in the special winning opening 41, and the game that has been fired is performed. Many of the spheres P are to be retained in the depressed portion V.
Therefore, it is possible to make it difficult for the player to interrupt the launch of the game ball and wait for the result when reaching the reach.
Note that the reach pattern is selected as the stop pattern, but in the case of losing, that is, even in the case of losing reach, the roller 97 is rotated backward (S68), and after a lapse of t1 time from the stop of the fluctuation display of all symbols (S70: (Yes, S72: Yes), the roller 97 is rotated forward (S74). If the reach flag is not set (S66: No), the roller 97 is rotated forward (S76).

[Effects of Embodiment]
(1) As described above, if the pachinko machine 1 of the above embodiment is used, the game ball is held at the dip portion V formed on the upper surface of the rotating rollers 97, 98 rotating in the opposite direction, and the roller 97 By switching the rotation direction of the game ball forward, the held game balls can be caused to flow down.
Therefore, unlike the conventional game machine, there is no danger that the game will be monotonous unlike a pachinko machine in which the distribution member continuously performs a constant operation during the game.

(2) Moreover, when the special symbol start storage number U1 becomes "4", the roller 97 rotates backward, and when the special symbol start storage number U1 becomes less than "4", the roller 97 moves forward. Therefore, if there is a game ball held in the depressed portion V at that time, the game ball flows down and wins the first type starting port 27 or the open ordinary electric accessory 28, and again, Since the special symbol start storage number U1 is likely to be “4”, the player fires the game ball even when the special symbol start storage number U1 is “4”, and starts the special symbol start. Immediately after the storage number U1 has become less than “4”, an attempt is made to return to “4” again.
Therefore, as in the prior art, when the special symbol start storage number U1 is "4", a situation occurs in which the player interrupts the firing of the game ball and tries to avoid wasteful consumption of the game ball. It can be difficult.

(3) When the reach pattern is selected as the stop pattern of the special symbol, that is, when the probability of occurrence of the big hit is high, the roller 97 rotates backward from the start of the change of the special symbol until the large winning opening 41 is opened. Since the game balls can be held in the depressed portion V, the player allows many game balls to flow down from the depressed portion V and make the large prize hole 41 win when the large winning opening 41 is opened. For this reason, the game ball is fired even while the special symbol is displayed in a variable manner.
Therefore, unlike the related art, it is possible to prevent a situation in which the emission of the game balls is interrupted until the special symbol is stopped to avoid wasteful consumption of the game balls.
In addition, the occurrence of the reach can be predicted by changing the rotation direction of the front roller that has been rotating forward to the rear.

(4) Further, by switching the rotation direction of the roller 97, the game balls can be held or the held game balls can be caused to flow down, so that the game balls can be held and flown down by a relatively simple structure. Can be controlled. In addition, since it is possible to produce a movement different from that of the conventional structure in which the rear end of the distribution member 508 is moved up and down with the rear end of the distribution member 508 as a rotation axis, the player can play a game with freshness that has never been seen before. it can.
