The random number for drawing (for drawing lottery) is extracted, and when there are four, the extraction of random numbers for special drawing lottery (for drawing lottery for ordinary drawing) is canceled. The lottery means 31 uses the random numbers for the special drawing lottery (for the ordinary drawing lottery) extracted by the random number extraction unit 25 as the special drawing lottery result (the ordinary drawing lottery result), and the free space for the special figure holding area (the ordinary drawing holding area) Store sequentially.

  As shown in FIG. 3, the lottery means 31 is able to start displaying the fluctuation of the special figure (ordinary figure), that is, not changing the special figure (general figure) and being in a big hit (during electric Chu operation). If not, the presence or absence of a special drawing lottery result (ordinary drawing lottery result) stored in the special figure reservation area (ordinary drawing reservation area) is checked. The lottery means 31 reads out the oldest of the special drawing lottery results (ordinary drawing lottery results) stored in the special figure holding area (normal drawing lottery area) and collates it with the special drawing lottery table (general drawing lottery table). .

  As described above, the lottery means 31 selects and uses a plurality of types of lottery tables corresponding to the winning opening and the gaming state. As a lottery result of the special drawing lottery, there are a probability variation jackpot, a non-probability variation jackpot and a loss. In this example, all the lottery results of the ordinary drawing lottery are wins. In this example, as described above, the jackpot probability in the special drawing lottery by winning at the start winning opening 17 is 1/300 in the normal state and the short time state, and 1/30 in the probability variation state. On the other hand, the probability of winning a jackpot by winning the specific winning opening 18 is 1/30 in all the game states of the normal state, the short time state, and the probability variation state. That is, in the normal state and the short time state, the player's advantage is 10 times greater when winning the specific winning opening 18 than when winning the starting winning opening 17.

  As shown in FIGS. 1 and 3, the variation pattern selection unit 33 is a unit that selects a variation pattern for displaying a special drawing lottery result on the liquid crystal display unit 191 as a special diagram display unit. Here, the fluctuation pattern is the special figure fluctuation time spent for displaying the special drawing lottery result, the number of pseudo stops that make it appear that the symbol has stopped temporarily, and the contents of the effect when displaying the special drawing lottery result. , A pattern in which stop symbols to be stopped and displayed in each symbol display area 190L, C, R are defined. The fluctuation pattern selection means 33 selects a fluctuation pattern by comparing a random number for special figure lottery as a special figure lottery result with the fluctuation pattern selection table. In the pachinko gaming machine 1 of this example, it is set as the descending condition that a specific variation pattern is selected by the variation pattern selection means 33. When this lowering condition is satisfied, a control signal for moving the slide rail 611 to the open position (FIG. 4B) is output from the main circuit 20 toward the sub-control circuit 43.

  As shown in FIGS. 1 and 3, the privilege granting unit 34 is a unit that generates a jackpot (privilege) according to a combination of stop symbols that are stopped and displayed on the liquid crystal display unit 191 as a special symbol display unit. In the privilege grant means 34, a state flag corresponding to the big hit state, the probability variation state, or the short time state is defined. When the combination of stop symbols is a jackpot symbol (a so-called double eye), the privilege granting unit 34 sets 1 as the flag value of the state flag and generates a jackpot state. The big hit state is a gaming state advantageous to the player side in which the round in which the big winning device (attacker) 16 is released is repeatedly executed until the number of winning balls reaches 10 or the opening time reaches 25 seconds.

  The privilege granting unit 34 repeatedly executes the round 15 times, resets the jackpot flag to an off state, and ends the jackpot state. The privilege granting means 34 transmits a big hit start instruction signal, a round start instruction signal, a big hit end instruction signal, etc. corresponding to the big hit state to the display control circuit 44. The big hit start instruction signal is a signal instructing the start of the big hit state. The round start instruction signal is a signal instructing the start of each round. The big hit end instruction signal is a signal instructing the end of the big hit state.

  The privilege granting means 34 generates a probability big jackpot when the combination of the stop symbols is an odd-numbered symbol, and sets 3 as the flag value of the state flag after the probability big jackpot ends, Generate a probabilistic state that continues until it occurs. The probability variation state is a state in which a special drawing lottery is performed by a special variation lottery table for probability variation. On the other hand, when the combination of the stop symbols is an even-numbered symbol, the non-probable variation big hit is generated, and after the end of the non-probable variation big win, 2 is set as the flag value of the state flag to generate a time-short state. The short-time state is a state in which a special drawing lottery is carried out using the special special drawing lottery table, and ends when one of the 100 symbol changes or the occurrence of a new jackpot is established. When the probability change state or the time reduction state ends, the state flag is reset to zero and the normal state is restored.

  The privilege grant means 34 includes a round counter (not shown) for counting the number of rounds executed in the big hit state, and a short time counter (not shown) for counting the number of special figure fluctuations in the short time state. The privilege granting unit 34 controls the occurrence period of the big hit state by the number of rounds counted by the round counter and also controls the occurrence period of the time reduction state by the number of special figure fluctuations counted by the hourly number counter. It should be noted that, in the probability variation state and the short time state, the opening time of the start winning opening (electrical chew) 17 at the time of the normal winning is prolonged, so that the degree of decrease of the player's ball is suppressed.

  Next, the operation of the pachinko gaming machine 1 of this example configured as described above will be described. First, the operation of the slide rail 611 during the game in the pachinko gaming machine 1 will be described. In the pachinko gaming machine 1 of this example, the initial position of the slide rail 611 is the closed position shown in FIG. When the slide rail 611 is located at the closed position, the opening end 621 of the firing ball passage 62 is located near “10 o'clock”, and the winning path R to the specific winning opening 18 is closed. When the variation pattern selection means 33 selects the specific variation pattern and the descending condition is satisfied, a control signal is output from the main circuit 20 to the sub-control circuit 43, and the slide rail 611 is accordingly displayed in FIG. It moves toward the open position shown in (B). After that, the open position is maintained until 30 seconds have elapsed or the rising condition, which is either to win 5 balls in the specific winning opening 18, is satisfied, and then the slide rail 611 is closed at the initial position. Return to position.

  The operation of such a pachinko gaming machine 1 will be described with reference to the flowcharts shown in FIGS. FIG. 6 shows a rough flow of the game by the pachinko gaming machine 1. As shown in the figure, in the pachinko gaming machine 1 of this example, the general start winning process P1, the specific start winning process P2, the special figure hold reading process P3, the special figure changing process P4, and the jackpot process P5 are processed in this order. As a result, the game is executed.

  FIG. 7 shows the flow of the general start winning process P1 which is a winning process corresponding to winning in the start winning opening 17. FIG. 8 shows the flow of the specific start winning process P2 which is a winning process corresponding to winning in the specific winning port 18. FIG. 9 shows the flow of the special figure reservation reading process P3 for reading the special figure lottery result from the special figure reservation area. FIG. 10 shows the flow of the special figure changing process P4 by the main circuit 20 for variably displaying symbols on the liquid crystal display unit 191. FIG. 11 shows the flow of the jackpot process P5 for generating a jackpot state.

  In the general start winning process P1 shown in FIG. 7, the main circuit 20 first determines whether or not a general start winning that is a win to the start winning opening 17 is detected (S101). When the general start winning is detected (S101: YES), the number of reserved special drawing lottery results in the special figure holding area is determined (S102). If the number of holdings is 3 or less (S102: YES), one of the random numbers generated by the random number counter 250 (random number at that timing) is extracted (S103), and the special figure holding area Is held (stored) as the latest special drawing lottery result (S104). On the other hand, when the general starting prize is not detected (S101: NO), or when the number of reserved special drawing lots in the special figure holding area is four (S102: NO), the random number extraction unit 25 extracts random numbers. Is not executed, and the general start winning process P1 is terminated.

  In the specific start winning process P2 shown in FIG. 8, first, the main circuit 20 determines whether or not a specific start winning that is a win to the specific winning opening 18 is detected (S201). When the specific start winning is detected (S201: YES), the number of reserved special drawing lottery results in the special figure holding area is determined (S202). When the number of holdings is 3 or less (S202: YES), one of the random numbers generated by the random number counter 250 (random number at that timing) is extracted (S203), and the special figure holding area Is held (stored) as the latest special drawing lottery result (S204). On the other hand, when the specific start winning is not detected (S201: NO), or when the number of reserved special drawing lottery results in the special figure holding area is four (S202: NO), the random number extraction unit 25 extracts random numbers. Do not execute.

  Thereafter, it is determined whether or not the ascent condition of the slide rail 611 is achieved (S205). When the rising condition (elapse of 30 seconds or any of the five ball winnings) is established (S205: YES), the slide rail 611 is raised to the closed position (FIG. 4 (A)). Move (S206).

  In the special figure hold reading process P3 shown in FIG. 9, the main circuit 20 first determines whether or not the special figure lottery result is held (stored) in the special figure hold storage area (S301). When there is a special drawing lot hold (S301: YES), the flag value of the status flag is determined (S302). If the flag value of the status flag is other than 1 (big hit state) (S302: NO), it is determined whether or not the special figure is being displayed on the liquid crystal display unit 191 (S303). If the special drawing is not being displayed (S303: NO), the oldest drawing of the special drawing lottery held in the special drawing storage area is read (S304), and the result is compared with the special drawing lottery table. The determination is executed (S305). The main circuit 20 determines a stop symbol and a variation pattern based on the determination result (S306), and executes a special diagram variation process P4 for displaying the special diagram in a liquid crystal display unit 191 as a special diagram display unit.

  On the other hand, when the special drawing lottery result is not put on hold (S301: NO), when the big hit game is occurring (S302: YES), or when the special drawing (common figure) is being displayed in a variable manner (S303: YES) ) Bypasses the special figure fluctuation process P4 and the like.

  In the special figure fluctuation process P4 shown in FIG. 10, the main circuit 20 first starts the fluctuation display of the special figure according to the fluctuation pattern selected by the fluctuation pattern selection means 33 (S401). Then, after the special figure fluctuation time defined in the selected fluctuation pattern has elapsed (S402: YES), the special figure fluctuation display is stopped (S403). Thereafter, it is determined whether or not the variation pattern selected by the variation pattern selection means 33 is the specific variation pattern (S404). When a specific variation pattern is selected (S404: YES), that is, when the lowering condition is satisfied, the slide rail 611 is moved to the open position shown in FIG. 4B (S405).

  Thereafter, it is determined whether or not the special drawing lottery result is a big hit (S406). If the special drawing lottery result is a big hit (S406: YES), the flag value of the status flag is set to 1 (big hit state) (S407). On the other hand, if the special drawing lottery result is not a big hit (S406: NO), the flag value of the status flag is determined (S410). When the flag value of the status flag is 2 (short time state) (S410: YES), the number of special figure fluctuations by the short time counter is added once (S411). When the number of special figure fluctuations by the hour / counter counter reaches 100 (S412: YES), the flag value of the state flag is reset to zero (normal state) (S413).

  Next, in the jackpot process P5 shown in FIG. 11, the main circuit 20 first determines the flag value of the status flag (S501). When the flag value of the status flag is 1 (big hit state) (S501: YES), the number of rounds by the round counter is added once (S502). Subsequently, the grand prize winning device (attacker) 16 is opened (S503), and then the prize winning device 16 is closed when the number of winning balls reaches 10 (S504) or when the opening time reaches 25 seconds (S503). S506).

  The main circuit 20 repeatedly executes the process of releasing the special winning device 16 as described above until the number of rounds by the round counter reaches 15 (S507). When the number of rounds reaches 15 (S507: YES), the number of rounds is reset to zero (S508), and it is determined whether or not it is a probable big hit (S509). If it is a probable big hit (S509: YES), the flag value of the status flag is set to 3 (probable change state) (S510). On the other hand, when it is not a probable big hit (S509: NO), the flag value of the status flag is set to 2 (time reduction state) (S520).

  As described so far, in the pachinko gaming machine 1 of this example, the position of the opening end 621 of the firing ball passage 62 differs depending on whether the slide rail 611 is in the open position or the closed position, and accordingly The presence / absence of a possibility of winning a prize at the specific winning opening 18 is determined. That is, when the slide rail 611 is located at the closed position and the open end 621 is located near “10 o'clock”, the winning path R to the specific winning opening 18 is closed and the specific start winning process P2 can be executed. Disappears. On the other hand, when the slide rail 611 is positioned at the open position and the open end 621 is positioned near “9 o'clock”, the winning path R to the specific winning port 18 is secured and the possibility of executing the specific start winning process P2 is possible. Can occur. Thus, according to the pachinko gaming machine 1 of this example, it is possible to provide different game characteristics depending on the position of the slide rail 611.

As described above, the pachinko gaming machine 1 of the present example is a gaming machine with excellent characteristics that enhances the interest of the game that the player can feel by realizing various gaming properties.
In this example, it is set that the specific variation pattern has been selected by the variation pattern selection means 33 as the descent condition for moving the slide rail 611 to the open position. As this descent condition, it is possible to set various conditions such as the number of special drawing lottery reaching a predetermined number instead of this example. Furthermore, it is also possible to separately execute a lottery for determining whether or not to move the slide rail 611 downward when winning the start winning opening 17, and to set the winning condition as the lowering condition.

  Moreover, it is also possible to provide a launch detection means for detecting the launch state of the game ball, and a measurement means for measuring the non-winning time, which is the elapsed time after the latest winning, with respect to the start winning opening 17. In this case, for example, the fact that the non-winning time has reached a predetermined time can be set as the descent condition.

  In this example, the slide rail 611 is temporarily lowered from the closed position to the open position in response to the establishment of the lowering condition, which is a predetermined condition. Instead, the predetermined lowering condition is satisfied. It is also possible to lower the slide rail 611 little by little every time. For example, if the slide rail 611 is lowered by one third every time the lowering condition is satisfied, the slide rail 611 is positioned at the open position when the lowering condition is satisfied three times.

  Further, for example, every time the non-winning time reaches 10 seconds, the slide rail 611 may be moved downward by one third. In this case, when a winning is made at the start winning opening 17 before the slide rail 611 reaches the open position, the slide rail 611 may be stopped and lowered.

  In addition, in this example, the start winning port 17 is provided in addition to the specific winning port 18 that is switched according to the position of the slide rail 611 as a chance winning port for the special drawing lottery. The opportunity prize opening may be only the specific prize opening 18. In this case, for example, the slide rail 611 may be lowered in response to detection of a passing ball by a passage detection sensor provided in the game area 13, and further, whether the slide rail 611 is lowered in response to detection of a passing ball. It is also possible to execute a lottery of no.

(Example 2)
This example is an example in which the driving method of the slide rail 611 is changed based on the pachinko gaming machine of the first embodiment. The contents will be described with reference to FIGS.
In the pachinko gaming machine according to the first embodiment, the slide rail 611 is driven by electrical control. In this example, the slide rail 611 is driven by a mechanical balance.

  As shown in FIG. 12, the slide rail 611 of the present example has an extending portion 611 </ b> E that extends downward with respect to the slide rail 611 of the first embodiment. Further, a movable piece 611D is attached to the tip of the extending portion 611E so as to be rotatable around a rotation shaft 611P incorporating a small motor. The extending portion 611E and the movable piece 611D form a ball holding portion 360 that can hold a game ball flowing down the game area 13. In the second state in which the movable piece 611D is rotated so as to form an elbow shape with respect to the extending portion 611E (the state indicated by the solid line in FIG. 12A), there are 20 ball retaining portions 360. It will be in the state which can store the game ball of a grade. On the other hand, in the first state in which the movable piece 611D is positioned substantially in a straight line with respect to the extending portion 611E (the state indicated by the broken line in FIG. 12A), the ball retaining portion 360 can play the game ball. It will not be stored.

  In this example, instead of the rail motor of Example 1 using electric power as a drive source (reference numeral 361 in FIG. 2), a rail motor 361 using an urging force of a spiral spring 361B as a drive source as shown in FIG. 13 is adopted. ing. As the slide rail 611 descends, the spiral spring 361B is wound up, and an urging force for raising the slide rail 611 to the closed position can be generated. That is, in this example, the rail motor 361 serves as a biasing unit that biases the slide rail 611 toward the closed position.

  In the pachinko gaming machine of this example, as shown in FIG. 12 and FIG. 13, a slide rail according to the balance between the weight of the game balls stored in the ball holding portion 360 and the urging force of the spiral spring 361 B of the rail motor 361. The position of 611 can be determined. When no game balls are stored in the ball holding portion 360, the slide rail 611 can be positioned at the closed position according to the urging force of the rail motor 361. On the other hand, when the number of game balls stored in the ball holding portion 360 becomes seven or more, the slide rail 611 can be positioned at the open position by the driving force according to the weight of the game balls.

  Further, the pachinko gaming machine of this example has a launch detection means (not shown) for detecting the launch state of the game ball, and a non-winning time which is an elapsed time after the special figure has finally stopped fluctuating. , And a non-winning time timer which is a measuring means for measuring about 17). The launch detection means of this example includes a handle sensor for detecting the operation amount of the launch handle. According to the handle sensor, it is possible to detect the launch state of the game ball.

In the game area 13, nails, a display device 19, and the like are arranged so that the game balls that have been placed always flow down near the start winning opening. Therefore, the fired state in the pachinko gaming machine of this example means a state in which a game ball is driven in aiming at the start winning opening. Instead, a nail or a display device 19 is arranged so that the start winning opening can be aimed only when the operation amount of the firing handle (launching strength of the game ball) is within a predetermined range, and the launching handle is within the predetermined range. It is also possible to define the state in which is operated as the launch state in the narrow sense, and operate the non-winning time timer in the narrow launch state.
Moreover, the detection method of a discharge state is not limited to the method using the detection result by the handle sensor of this example. A sensor may be installed in the vicinity of the firing ball passage 62, the start winning opening, or the like, and the firing state may be detected based on a detection result by the sensor. In particular, when adopting the narrow launch state, a configuration in which sensors are arranged around the start winning opening can be effective.

  A non-winning time timer that is a measuring means measures a non-winning time during detection of a firing state by the firing detecting means. In the pachinko gaming machine, the fact that the non-winning time has passed 5 seconds is set as an operating condition for rotating the movable piece 611D to the second state in which the game balls can be stored. In addition, winning at the start winning opening is set as a return condition for rotating the movable piece 611D rotated to the second state in which the game balls can be stored toward the first state in which the game balls cannot be stored. .

  The operation of the pachinko gaming machine of this example configured as described above will be described with reference to the flowcharts of FIGS. FIG. 14 shows a flow of a general start winning process P1 which is a winning process corresponding to a winning at the start winning opening. FIG. 15 shows the flow of the special figure changing process P4 for displaying the symbols in a variable manner on the liquid crystal display unit 191 as the special figure display unit.

  In the general start winning process P1 shown in FIG. 14, the main circuit 20 first determines whether or not a general start winning that is a win to the start winning opening is detected (S111). When the general start winning is detected (S111: YES), it is determined whether or not the non-winning time timer is operating (S112). When the non-winning time timer is operating (S112: YES), the measurement time (timer value) is reset to zero (S113), and then the rotation state of the movable piece 611D is determined (S114). When the movable piece 611D is in the second state (a state where the game balls can be stored) (S114: YES), the movable piece 611D is rotationally driven to a first state where the game balls cannot be stored (S115). Thereafter, the number of reserved special drawing lottery results in the special figure holding area is determined (S116). If the number of holds is 3 or less (S116: YES), one of the random numbers generated by the random number counter (reference numeral 250 in FIG. 3) (random number at that timing) is extracted ( S117), the latest special drawing lottery result is held (stored) in the special figure holding area (S118).

  On the other hand, when the general start winning is not detected (S111: NO), the operation state of the launch handle, that is, the launch state of the game ball is determined (S120). Only when it is not in the firing state (S120: NO), the measurement time of the non-winning time timer is reset to zero (S121). Thereafter, the time measured by the non-winning time timer is determined (S122), and when the time measured by the non-winning time timer has passed 5 seconds (S122: YES), the game balls are placed in the second state in which the game balls can be stored. The movable piece 611D is rotationally driven (S123). In addition, when the measurement time of the non-winning time timer has not passed 5 seconds (S122: NO), or when the general start winning is detected but the number of reserved special drawing lottery is 4 (S116: NO) The random number counter generated by the random number counter is not extracted, and the general start winning process P1 is terminated.

  In the special figure fluctuation process P4 shown in FIG. 15, the main circuit 20 first starts the fluctuation display of the special figure according to the fluctuation pattern selected by the fluctuation pattern selection means (reference numeral 33 in FIG. 3) (S421). Thereafter, after the special figure fluctuation time specified in the fluctuation pattern has elapsed (S422: YES), the special figure fluctuation display is stopped (S423). Subsequently, it is determined whether or not the special drawing lottery result is held (S424). If there is no special drawing lottery result held (S424: YES), the game ball is fired depending on whether or not the firing handle is operated. It is determined whether or not it is in a state (S425). When the firing handle is being operated (S425: YES), the time counting by the non-winning time timer is started (S426). On the other hand, when there is a suspension of the special drawing lottery result (S424: NO), and when the launching handle is not operated and the game ball is not being launched (S425: NO), the timing start process by the non-winning time timer Detour (S426).

  Thereafter, it is determined whether or not the special drawing lottery result is a big hit (S427). If the special drawing lottery result is a big hit (S427: YES), the flag value of the status flag is set to 1 (big hit state) (S428). On the other hand, when the special drawing lottery result is not a big hit (S427: NO), the flag value of the status flag is determined (S438). When the flag value of the state flag is 2 (short time state) (S438: YES), the special figure fluctuation count by the short time counter is added once (S439). When the number of special figure fluctuations by the time reduction counter reaches 100 (S440: YES), the flag value of the state flag is reset to zero (normal state) (S441).

  As described above, in the pachinko gaming machine of this example, when the winning at the start winning opening is interrupted for 5 seconds or longer, the movable piece 611D can be rotated so that the game balls can be stored in the ball holding portion 360 ( Second state). Then, the slide rail 611 can be lowered toward the open position (FIG. 12B) according to the weight of the game balls stored in the ball holdable portion 360. When the slide rail 611 descends to the open position, the winning path R to the specific winning opening 18 is opened, and the degree of expectation for the lottery process corresponding to the winning to the specific winning opening 18 is increased.

  On the other hand, if a winning to the start winning opening 18 occurs when the movable piece 611D is in the second state, the movable piece 611D returns to the first state, and the ball holding portion 360 cannot store the game ball, The stored game balls are discharged. In this state, the slide rail 611 moves to the closed position (FIG. 12A) in accordance with the urging force of the rail motor 361 that is the urging means. In this state, the winning route R to the specific winning opening 18 is closed, and the possibility of winning is lost.

Other configurations and operational effects are the same as those in the first embodiment.
In addition, instead of the biasing means including the rail motor 361 that houses the spiral spring 361B, biasing means including a string spring that engages with the slide rail 611 may be employed. For example, if the lower end portion of the string-wound spring arranged in the vertical direction is engaged with the vicinity of the upper end of the slide rail 611 and the upper end portion is engaged with the pachinko gaming machine main body, the slide rail 611 is biased by the biasing force of the string spring. Can be lifted toward the closed position.

  As mentioned above, although the specific example of this invention was demonstrated in detail, this specific example only discloses an example of the technique included by a claim. Needless to say, the scope of the claims should not be construed as limited by the configuration, numerical values, or the like of the specific examples. The scope of the claims includes techniques obtained by variously modifying or changing the specific examples using known techniques, knowledge of those skilled in the art, and the like.
