  Thus, the image control unit 400c causes the CPU 433 to execute an image display control program stored in advance in the ROM 434 according to a predetermined flowchart (not shown), and during this execution, based on command control from the effect processing unit 400b. The image display 50, the two speakers SP, the notification lottery symbol display 180, and the both notification lottery symbol holding lamps 190 are subjected to various arithmetic processes required to drive or control both.

  The lamp control unit 400d includes a microcomputer, and the lamp control unit 400d includes a bus line 440 and an I / F 441, an O / F 442, a CPU 443, a ROM 444, and a RAM 445 that are connected to each other via the bus line 440. It has.

  Accordingly, the lamp control unit 400d executes a lamp control program stored in advance in the ROM 444 by the CPU 443 in accordance with a predetermined flowchart (not shown). During this execution, based on command control from the effect processing unit 400b, The frame lamp LP, the star-shaped disk lamp 90, and the star-shaped movable accessory 120 are all subjected to various arithmetic processes required for drive control.

  In the present embodiment configured as described above, the game board Ba of the pachinko gaming machine is assembled as follows. First, the game board 10 shown in FIGS. 2 and 3 is prepared. Next, a large number of game nails 41 and a predetermined number of game nails 42 in the group of game nails 40 are dispersed as shown in FIG. 2 or FIG. 4, using an appropriate nail driver (not shown), It is driven into the front surface 11 of the game board 10. In addition, the windmill 80 is also assembled | attached to the front surface 11 of the game board 10 through the one game nail 41 in the position shown in FIG.

  Thereafter, the inner rail portion 20a and the outer rail portion 20b of the guide rail 20 are assembled to the front surface 11 of the game board 10 at each position shown in FIGS. Thereby, the game area 12 is specified by the guide rail 20 on the front surface 11 of the game board 10.

  As described above, by assembling the guide rail 20, the predetermined number of game nails 42 in the game group 40 are located near the upper end of the one end portion 21 of the inner rail portion 20a as shown in FIG. 2 or FIG. It will be located close to other neighborhoods.

  When the assembly of the guide rail 20 to the front surface 11 of the game board 10 is completed as described above, the ball return prevention device 200 is detachably assembled to the one end portion 21 of the inner rail portion 20a as follows.

  First, as shown in FIG. 5, the ball return preventing device 200 assembled as described above is aligned with both outer surfaces of the one end portion 21 of the inner rail portion 20 a on the outer surfaces of the main member 200 a and the sub member 200 b. Grab so that

  More specifically, the ball return prevention device 200 is configured such that the first protrusion 223 of the elastic piece 220c of the main member 200a and the inclined surface 224 of the side wall 240b of the sub member 200b have the one end portion 21 of the inner rail portion 20a. It grips so that it may oppose one side edge part (side edge part on the opposite side to the front surface 11 side of the game board 10 of the one side front-end | tip part 21).

  Thereafter, the ball return prevention device 200 is moved as it is toward the one end portion 21 of the inner rail portion 20a. Accordingly, the one end portion 21 of the inner rail portion 20a extends from the one side edge portion to the inclined end surface 223b of the first engaging portion 223 of the elastic piece 220c of the ball return prevention device 200 and the side wall of the sub member 200b. It is inserted between the inclined surface 244 of the part 240b.

  At such a stage, the ball return prevention device 200 is further moved in the same direction as described above. Then, since the one end portion 21 on the inner rail portion 20a has the predetermined plate thickness, the first protruding portion 223 of the elastic piece 220c resists the elastic force of the elastic piece 220c, and the sub member 200b It moves to the side opposite to the side wall 240b. This means that the elastic piece 220c is gently curved to the opposite side with respect to the side wall portion 220b.

  Thus, by moving the ball return prevention device 200 further in the same direction as described above under the curvature of the elastic piece 220c, the one end portion 21 on the inner rail portion 20a is moved to the U-shaped plate. It passes between the side wall part 240b of 240 and the 1st protrusion part 223 of the elastic piece 220c, and is inserted between the both protrusion wall parts 243 and 242 of the U-shaped wall part 240a and the second protrusion part 224 of the elastic piece 220c. .

  Here, since the inclined surface 244 of the side wall portion 240b and the inclined end surface 223b of the first projecting portion 223 are inclined so as to open to each other in an eight-letter shape, the one-side tip portion 21 has the side wall portion 240b and the elastic piece. It is possible to smoothly enter between the flat end surface portion 223a of the first protrusion 223 of 220c.

  Moreover, since the parallel end surface part 223a of the 1st protrusion part 223 is located higher to the U-shaped wall part 240a side than the parallel end surface part 224a of the 2nd protrusion part 224, the one side front-end | tip part 21 is 2nd. Without being caught by the parallel end surface portion 224a of the protruding portion 224, it passes between the parallel end surface portion 224a and the U-shaped wall portion 240a and is inserted into the side wall portion 220b side of the main member 200a. Here, since the inclined end surface portion 224b of the second protrusion 224 is inclined to the opposite side of the U-shaped wall portion 240a along the extending direction of the elastic piece 220c, the one-side distal end portion 21 is further increased. It can be easily inserted between the parallel end surface part 224a of the second protrusion 224 and the U-shaped wall part 240a.

  In response to such insertion, the second protruding portion 224 of the elastic piece 220c engages in the through hole portion 21c of the one-side tip portion 21, and the leg portion 21b of the one-side tip portion 21 is the first protrusion. It is sandwiched between the portion 223 and the base portion 222 a of the elastic piece main body 222. Along with this, the elastic piece 220c returns to its original shape by its elastic force.

  This is because the one end portion 21 of the inner rail portion 20a is engaged with the second protruding portion 224 of the elastic piece 220c at the through hole portion 21c of the leg portion 21b, and the first protruding portion at the leg portion 21b. In a state of being sandwiched between the portion 223 and the base portion 222a of the elastic piece body 222, the elastic piece body 222 is sandwiched between the protruding portions 242 and 243 of the U-shaped wall portion 240a.

  Therefore, the ball return prevention device is firmly engaged with the one end portion 21 of the inner rail portion 20a without being separated from the one end portion 21 by engagement with the through hole portion 21c of the leg portion 21b of the second projecting portion 224. It can be held by the side tip 21. Here, the one end portion 21 on the inner rail portion 20a is sandwiched between the first protrusion 223 and the base portion 222a of the elastic piece main body 222 by the leg portion 21b. It can be firmly held by the one-side tip portion 21 without tilting to the front side of the board surface 11 of the game board Ba along the surface of the one-side tip portion 21 of the rail portion 20a.

  When the assembly of the ball return prevention device 200 is completed in this way, the center structure 30, the start chucker 60a, the electric tulip 60b, the through gate 70, the respective normal winning openings 90, the first attacker 100, the respective star disk lamps 110, and Each star-shaped movable accessory 120 and other parts in front of the board are assembled to the front surface 11 of the game board 10 at each position shown in FIG.

  Next, the image display 50 is disposed on the back surface of the game board 10 so that the liquid crystal panel 51 faces the front from the central opening of the game board 10. Then, the board back part in game board Ba is assembled | attached to the game board 10 from the back surface side. The assembly of the game board Ba is completed through the above assembly process.

  In the assembly process of the game board Ba as described above, when the ball return prevention device 200 is assembled, the ball return prevention device 200 is assembled from the one side edge portion side to the one end portion 21 of the inner rail portion 20a. It is done. In other words, the ball return prevention device 200 is not assembled from the upper side to the one end portion 21 of the inner rail portion 20a along the front surface 11 of the game board 10, but from the front of the front surface 11 of the game board 10 to the inner side. The rail portion 20a is assembled toward the front surface 11 along the width direction of the one end portion 21 (direction along the surface of the one end portion 21).

  Therefore, as described above, even if each game nail 42 is located in the vicinity of the upper side of the one end portion 21 of the inner rail portion 20a or in the vicinity of the other vicinity, the game nail 42 is connected to the inner rail portion 20a. The ball return prevention device 200 can be smoothly assembled to the one side tip portion 21 of the inner rail portion 20a without interfering with the work of assembling the ball return prevention device 200 to the one side tip portion 21.

  In addition, as described above, in the state where the assembly of the ball return prevention device 200 with respect to the one side tip portion 21 of the inner rail portion 20a is completed, the inner rail portion 20a is at the one side tip portion 21 of the elastic piece 220c. Under the elastic force, the elastic piece 220c is firmly sandwiched between the U-shaped wall 240a. In addition, the elastic piece 220c is engaged with the second protruding portion 224 by fitting the one end portion 21 on the inner rail portion 20a into the through-hole portion 21c. Furthermore, the one-side distal end portion 21 abuts from the inside to a portion of the side wall portion 220b that extends downward from the slit wall portion 220 at the head portion 21a, and at the leg portion 21c, the elastic piece 220c The base end portion 222a and the first projecting portion 223 are firmly held. Therefore, the ball return prevention device 200 is firmly attached to the one side tip portion 21 of the inner rail portion 20a without tilting to the front side of the front surface 11 of the game board 10 with respect to the one side tip portion 21 of the inner rail portion 20a. Assembled.

  After the game board Ba that has been assembled as described above is fitted to the frame body of the game machine main body B with the game board 10, the pachinko game machine is put into an operational state in which the game can be performed by turning on the power. For example, the main control device 300 enters an operating state together with the sub control device 400. Along with this, the soft timer 370 of the main controller 300 is reset to start timing, and a pulse signal is generated every 4 (ms) after the start. Therefore, main controller 300 repeatedly executes the timer interruption program according to the flowchart of FIG. 21 by CPU 360 every time a pulse signal from soft timer 370 is generated.

  Further, with the start of operation of the sub control device 400, the payout control unit 400a, the effect control unit 400b, and the lamp control unit 400d all start to operate. Then, the payout control unit 400a starts execution of the payout control program by the CPU 413, and the effect control unit 400b starts execution of the effect control program by the CPU 425 according to the flowchart of FIG. 400 c starts execution of the display control program by the CPU 433, and the lamp control unit 400 d starts execution of the lamp control program by the CPU 443.

Hereinafter, the operation of the pachinko gaming machine will be described by dividing it into a plurality of operation modes.
1. Non-Game Operation Mode At the present stage, the pachinko gaming machine is in an operation state when its power is turned on, and is in a state of waiting for a player to start a game. Note that the “no-game mode” refers to a mode in which a player does not yet play a game in the pachinko gaming machine (a mode corresponding to a so-called vacant state).

  Thus, each time the soft timer 370 generates a pulse signal as the main controller 300 starts operating when the power is turned on, the timer interrupt program is interrupted. This means that the execution of the timer interrupt program is repeated every 4 (ms) after the start of the operation of the main controller 300, and the time for executing the timer interrupt program is 4 (ms). It is maintained for a while.

  First, when the soft timer 370 generates the first pulse signal, the timer interrupt program is started at the start step by an interrupt based on the first pulse signal. Then, in the random number update processing routine 500, the jackpot random number data RNA, the jackpot symbol random number data RNB, the reach random number data RNC, the variation pattern random number data RND, and the hit random number data RNE are respectively expressed by the following equations (1) to (5). Based on the above, addition is updated by “1”.

RNA = RNA + 1 (1)
RNB = RNB + 1 (2)
RNC = RNC + 1 (3)
RND = RND + 1 (4)
RNE = RNE + 1 (5)
Here, random numbers follow a numerical sequence (for example, 0 to 299), start with an initial value “0” at the same time as the power to the pachinko machine is turned on, and sequentially increment by “1” to obtain a final value. When “299” is reached, the initial value “0” is restored by reset.

  Therefore, the period when the random number reaches a certain random number value is constant. “Random number” refers to a certain number in a sequence consisting of numbers that are random and have the same appearance frequency as a whole. For example, this random number is selected by the image display 50 in the jackpot random number data RNA. Prior to displaying the availability, a random number value corresponding to the winning time of the game ball at the start winning opening 61 is used to determine whether or not a winning combination such as a special prize is won.

  At this stage, since the operation of the main controller 300 is started, in the random number update processing routine 500, initial values of RNA, RNB, RNC, RND, and RNE on the left sides of the equations (1) to (5) Are both “0”. Accordingly, in the formulas (1) to (5), RNA = 1, RNB = 1, RNC = 1, RND = 1, and RNE = 1 are set (see FIGS. 22A to 22E).

  Thereafter, the timer interruption program proceeds to the start port processing routine 600 (see FIGS. 21 and 24). At this stage, since there is no winning of the game ball at the start winning opening 61, it is determined NO in step 610 (see FIG. 24) based on the output of the corresponding start winning sensor S1. Accordingly, when the timer interruption program proceeds to the next gate processing routine 700 (see FIG. 21 and FIG. 25), there is no passage of the through gate 70 by the game ball at this stage, so the corresponding gate sensor Based on the output of S3, NO is determined in step 710 (see FIG. 25).

  Accordingly, when the timer interruption program passes through the processing routine 800 (see FIG. 21) based on the next sensor output and proceeds to the winning ball processing routine 900, there is no game ball winning at this stage as described above. From the above, the timer interruption program proceeds to the next special symbol processing routine 1000 (see FIGS. 21 and 26).

  In the special symbol processing routine 1000, at this stage, the game by the player has not yet started, and the gaming state is neither the big hit gaming state nor the symbol variation state. Accordingly, since neither the jackpot nor the fluctuation is in progress, the determinations in both steps 1010 and 1020 are sequentially NO. At this stage, since the game ball is not yet held, the determination in step 1030 is also NO. Accordingly, the timer interruption program proceeds to the next normal symbol processing routine 2000 (see FIGS. 21 and 31).

  In this normal symbol processing routine 2000, since the gaming state of the pachinko gaming machine is neither an auxiliary gaming state nor a fluctuating state, NO is sequentially determined in each step 2100, 2200. Further, since there is no passage of the through gate 70 by a game ball at this stage, the determination at 2300 is also NO based on the output of the corresponding gate sensor S3. Accordingly, the timer interruption program proceeds to the next big prize opening processing routine 3000 (see FIGS. 21 and 32).

  In the big prize opening processing routine 3000, in the big hit time release processing subroutine 3100 (see FIG. 33), at the present stage, there is no game yet, and therefore no big hit is made, so it is determined NO in step 3110. The Next, in the small hitting time release processing routine 3200 (see FIG. 34), since it is not opening or ending at this stage, NO is sequentially determined in steps 3210 and 3230. “Opening” means that the effect processing by the image display 50 is in the opening effect state of the small hit gaming state which is performed at the start of the small hit gaming state. “Ending” means that the effect processing by the image display 50 is in the effect state from the end of the small hit to the start of the next fluctuation.

  Next, at the present stage, since the first big prize opening 102 is not opened and there is no prize winning in the first big prize opening 102, it is judged as NO in Step 3240. Note that in “C <9” in Step 3240, “C” represents the number of winning game balls to the first big winning opening 102, and “9” is the first big winning in the small hit gaming state. This is the upper limit number of winning game balls to the mouth 102.

  With the determination of NO in step 3240 as described above, the processing of the special winning opening processing routine 3000 ends, and the timer interruption program proceeds to the next electric chew processing routine 4000 (see FIGS. 21 and 35). Then, at the present stage, since the gaming state of the pachinko gaming machine is not in the auxiliary gaming state, the auxiliary gaming is not in progress. For this reason, the determination in step 4100 is NO.

  Accordingly, the timer interruption program proceeds to the next output processing routine 5000. At the present stage, since the player's game by the pachinko gaming machine has not been started, in the main controller 300, the CPU 360 outputs a command indicating a state of waiting for the player's game to the sub controller 400.

  Thus, when the processing of the output processing routine 5000 ends as described above, the timer interrupt program proceeds to the initial value random number update routine 6000. Here, when the final value in the random number sequence (for example, 0 to 299) is expressed, the initial value of the next random number is determined by a random value. For example, when the random number is added and updated from the initial value “0” to the final value “299”, the next initial value is not “0” but an arbitrary value in the random number sequence. This is useful for changing the initial value every time the random number makes one round so that periodicity does not appear when a specific random number appears.

  When the timer interrupt program proceeds to the initial value random number update routine 6000 as described above, the initial value random number data RNF is added and updated by “1” based on the following equation (6) (see FIG. 22F). ).

RNF = RNF + 1 (6)
Here, after the timer interruption program proceeds to the initial value random number update routine 6000 as described above, the time given to the execution of the initial value random number update routine 6000 is from the start of the random number update processing routine 500 to the output processing routine 5000. This is the remaining time obtained by subtracting the time required to complete the process from 4 (ms). Therefore, for the remaining time, in the initial value random number data RNF, the random numbers are sequentially “1” from 0 to 299 based on the equation (6) under the closed loop processing of the initial value random number update routine 6000. It is repeatedly added and updated one by one.

  When the soft timer 370 generates a pulse signal subsequent to the first pulse signal, the main control device 300 escapes from the closed loop processing of the initial value random number update routine 6000 by the CPU 360, and The timer interrupt program is started again from the start step. At this time, the initial value random number data RNF is set as the initial value of the jackpot random number data RNA in the next random number update processing routine 500 with the random number immediately before exiting from the closed loop processing of the initial value random number update routine 6000 described above.

  Accordingly, when execution of the timer interruption program is started again from the start step as described above, the random number update processing routine 500 determines that the random number of the jackpot random number data RNA is based on the equation (1) and the initial value random number update routine described above. The random number of the initial value random number data RNF immediately before exiting from the closed loop processing of 6000 is added and updated by “1” as the initial value. Note that the jackpot symbol random number data RNB, the reach random number data RNC, the fluctuation pattern random number data RND, and the hit random number data RNE are respectively added and updated by “1”.

  Next, the timer interruption program is executed from the start port processing routine 600 to the output processing routine 5000 in the same manner as described above, and the process proceeds to the execution of the initial value random number update routine 6000. Along with this, the random number of the initial value random number data RNB is repeatedly updated by “1” sequentially from 0 to 299 based on Expression (6) under the closed loop processing of the initial value random number update routine 6000. Is done.

Thereafter, whenever the soft timer 370 sequentially generates pulse signals, that is, every 4 (ms) after the operation of the main controller 300 starts, the timer interrupt program is executed by interruption. Each time this interrupt is executed, in the random number update processing routine 500, the value of the initial value random number data RNB is set as the initial value of the jackpot random number data RNA in the closed loop processing of the initial value random number update routine 6000. Based on the formula (1), “1” is added and updated, and the jackpot symbol random number data RNB, the reach random number data RNC, the fluctuation pattern random number data RND, and the hit random number data RNE are each “1”. , Addition update. Then, for each addition update as described above, the processing of the start port processing routine 600 to the initial value random number update routine 6000 subsequent to the random number update processing routine 500 is repeated in the same manner as described above.
2. Game operation mode In the state of the non-game operation mode as described above, a player receives a game ball and starts playing with the pachinko gaming machine, and puts the operation state of the pachinko gaming machine into the game operation mode. Shall. Hereinafter, this game operation mode will be described by dividing it into a main control device side game operation mode and a multiple control device side game operation mode.
(1) Main controller side game operation mode As described above, when the player starts the game, if the handle H of the pachinko gaming machine is rotated, the game balls are sequentially guided by the ball launcher. It is launched into the game area 12 through the rail 20.

Even in such a stage, the timer interrupt program is repeatedly executed in the same manner as described above every time a pulse signal from the soft timer 370 is generated. Each time the timer interrupt program is executed, in the random number update processing routine 500, the jackpot random number data RNA, the jackpot symbol random number data RNB, the reach random number data RNC, the fluctuation pattern random number data RND, and the hit random number data RNE are as described above. Similarly, addition updating is performed.
(1) Start Port Processing When the update processing of the random number update processing routine 500 is completed as described above, the timer interrupt program proceeds to the start port processing routine 600 (see FIGS. 21 and 24). In general, the start port processing routine 600 sets a jackpot lottery random number on the premise of winning a game ball to the winning start port 62 in order to form a jackpot lottery opportunity as described later. Hereinafter, the processing of the start port processing routine 600 in the game operation mode will be described in detail.

  As described above, the game balls sequentially fired into the game area 12 roll down along the board surface of the game board Ba via the game nails of the game nail group 40. In such a process, when the game ball wins the start winning opening 61 of the start chucker 60a, the winning of the game ball to the start winning opening 61 is detected by the start winning opening sensor S1.

  At this time, if the timer interruption program proceeds to step 610 of the start opening process routine 600, in this step 610, based on the detection output of the start winning opening sensor S1, as a winning to the start winning opening 61 of the game ball, It is determined as YES. Thereafter, it is determined in step 620 whether U <4. U represents the number of game balls held.

  At this stage, if U = 0, it is determined YES in step 620, and in the next step 621, the holding number U is calculated based on the following equation (7).

U = U + 1 (7)
Here, as described above, since U = 0, the number of holds U = 1 is calculated based on the equation (7).

  Next, in the random number setting process in step 622, the jackpot random number data RNA, jackpot random number data RNB, reach random number data RNC, fluctuation pattern random number data RND, hit random number data RNE and reach random numbers in the random number update processing routine 500 (see FIG. 21). Each latest random number of the data RNC is set in the RAM 390. Note that the set refers to a storage process.

  Thereafter, when the game balls sequentially fired into the game area 12 as described above further win the start winning opening 61, the respective winnings of the respective game balls to the start winning opening 61 are started sequentially. It is detected by the winning prize sensor S1.

  Accordingly, every time the timer interruption program proceeds to the start port processing routine 600 again, YES is determined in step 610, YES is determined in step 620, and in step 621, the addition processing of the holding number U is performed based on the equation (7). In step 622, the latest random numbers of the jackpot random number data RNA, jackpot random number data RNB, reach random number data RNC, variation pattern random number data RND, and hit random number data RNE at the current stage are set in the RAM 390 in the same manner as described above. Is done. In such a state, if U ≧ 4 is established based on the latest number of holds U in step 621, NO is determined in the subsequent step 620.

As described above, assuming that the number of holds U <4, every time the number of holds U is added and updated, in step 622, a big hit lottery random number setting process is performed to form a jackpot lottery opportunity.
(2) Gate processing The timer interrupt program proceeds to the gate processing routine 700 upon completion of the start port processing routine 600 as described above. In general, the gate processing routine 700 sets a random number for winning lottery on the premise that a game ball passes through the through gate 70 in order to form a chance of winning lottery as described later. Hereinafter, the processing of the gate processing routine 700 in the game operation mode will be described in detail.

  In the gate processing routine 700, it is determined in step 710 whether or not the through gate is passed. At the present stage, when the game ball fired as described above passes through the through gate 70, the passage of the game ball to the through gate 70 is detected by the gate sensor S3. Accordingly, in step 710, YES is determined based on the detection output of the gate sensor S3.

  Next, at step 720, it is determined whether G <4. Here, when G <4, G represents the number of reserved game balls that have passed through the through gate 70. If G = 0 at the present stage, YES is determined in step 720. Accordingly, in the next step 721, G = 1 is added and updated based on the following equation (8).

G = G + 1 (8)
After the process in step 721, in the next lottery random number setting process in step 722, the latest random number of the hit random number data RNE in the random number update processing routine 500 (see FIG. 21) is set as the win lottery random number.

  Thereafter, when the game balls sequentially fired into the game area 12 as described above further pass through the through gate 70, the passage of these game balls to the through gate 70 is sequentially detected by the gate sensor S3. Is done.

  Therefore, every time the timer interruption program proceeds to the gate processing routine 700 again, YES is determined in step 710, YES is determined in step 720, and the addition update of the holding number G is performed based on the equation (8) in step 721. In step 722, the latest random number of the winning random number data RNE at the current stage is set as the winning random number, as described above. In such a state, if G ≧ 4 is established, NO is determined in step 720.

As described above, assuming that the number of holds G <4, every time the number of holds G is updated, a winning lottery random number setting process for forming a winning lottery opportunity is performed in step 722.
(3) Processing Based on Sensor Output Next, when the timer interruption program proceeds to the processing routine 800 (see FIG. 21) based on the sensor output, each of the above-described start winning mouth sensor S1 or gate sensor S3 is processed in this processing routine 800. The detection output is set in the RAM 390.
(4) Prize Ball Processing Thereafter, when the timer interruption program proceeds to the next prize ball processing routine 900 (see FIG. 21), in the prize ball processing routine 900, the above described game ball start winning opening 61 is entered. A prize ball command corresponding to the number of winning prizes or a command corresponding to the number of game balls passing through the through gate 70 is set.
(5) Special Symbol Processing Next, when the timer interruption program proceeds to the special symbol processing routine 1000, it is determined in step 1010 (see FIG. 26) whether or not the jackpot is being hit. At the current stage, if the change start processing has already been completed in step 1310 (see FIG. 26), it is determined that the game is a jackpot game, that is, a jackpot game.

  On the other hand, if the variation start process in step 1310 has not yet been performed at this stage, it is not a big hit, and therefore NO is determined in step 1010. Then, in the next step 1020, it is determined whether or not it is changing. At the present stage, as described above, the variation start process in step 1310 is not performed, the determination in step 1020 is NO, and in step 1030, it is determined whether U ≧ 1.

  Therefore, if the latest number of holds in the start port processing routine 600 is U = 0, U ≧ 1 is not established, so that it is determined as NO in Step 1030. On the other hand, if the latest number of holds in the start port processing routine 600 is U ≧ 1, it is determined YES in step 1030, and in step 1031 the number of holds U is subtracted and updated based on the following equation (9). The

U = U-1 (9)
After the processing in step 1031, the special symbol processing routine 1000 proceeds to the jackpot determination processing subroutine 1100 (see FIGS. 26 and 27). Then, in the jackpot lottery random number setting process in step 1110, the latest random number of the jackpot random number data RNA set in step 622 of the start port processing routine 600 is selected and set. Thereafter, in step 1120, it is determined whether or not a big hit.

  Here, the jackpot means a 15-round jackpot for the purpose of acquiring a large amount of game balls, and a 2-round jackpot for the purpose of acquiring a large number of game balls. In this embodiment, the 15-round jackpot for the purpose of acquiring a large number of game balls is 15 rounds, and the number of game balls won in the first big winning opening 102 for each round is 9 or the first big A jackpot where the opening time of the winning opening 102 is 30 (seconds). Further, the two-round jackpot that is not intended to acquire a large amount of game balls means a jackpot in which the opening time of the first winning prize port 102 is 0.5 (seconds) for each round over two rounds. In “15 round jackpot” and “2 round jackpot”, “round” refers to the number of times the first grand prize winning opening 102 is opened.

  In the present embodiment, the jackpot is specified by a random value in the jackpot random number table TB1 (see FIG. 23A), for example, “7”. If the latest jackpot lottery random number in step 1110 is not the random number “7”, the determination in step 1120 is NO, and the lost symbol is set in the lost symbol setting process in the next step 1121. This means that in step 1120, a lottery with a loser has been made.

  On the other hand, if the latest jackpot lottery random number is “7”, it is determined as YES in step 1120. This means that a lottery with a jackpot was made. Then, in the jackpot symbol selection random number setting process in the next step 1122, the latest random number in the jackpot symbol random number table TB2 (see FIG. 23B) that has been set in step 622 of the start port processing routine 600 is selected. Set.

  Next, in step 1130, it is determined whether or not the symbol is a probable variation. In this embodiment, it is assumed that the probability variation symbol is specified by a random value in the jackpot symbol random number table TB2, for example, “7”. If the latest jackpot symbol selection random number in step 1122 is not “7”, it is not a random number value corresponding to a probability variation symbol. Therefore, after it is determined NO in step 1130, normal symbol set processing in the next step 1131 is performed. In the above, the normal symbol is set.

  On the other hand, if the above-mentioned latest jackpot symbol selection random number is “7”, since it is a random number corresponding to a probability variation symbol, it is determined YES in step 1130, and then in the probability variation symbol set process in step 1132, Probability pattern is set.

  When the processing of the jackpot determination processing subroutine 1100 is completed in this way, the special symbol processing routine 1000 proceeds to the next variation pattern selection processing subroutine 1200 (see FIGS. 26 and 28). Then, in the variation pattern selection random number setting process in step 1210, the latest random number of the variation pattern random number data RND in the random number update processing routine 500 (see FIG. 21) is set as the variation pattern selection random number.

  Thereafter, in step 1220, it is determined whether or not a big hit. Here, if it is a big hit based on the determination of YES in step 1120 based on the random number for jackpot lottery in step 1110 (see FIG. 27), it is determined YES in step 1220.

  Next, in step 1230, it is determined whether or not a short hit has occurred. Here, the short win is a winning to the first big winning opening 102 that does not aim to acquire a large amount of game balls such as a big hit of two rounds. However, with the end of the short hit game, the gaming state is changed to the probability changing gaming state.

  Therefore, if it is not a short hit, it is a big hit of 15 rounds. Therefore, after it is determined NO in step 1230, a table for specifying the big win is set in the big hit table setting process in step 1231. The jackpot table is stored in advance in the ROM 380 as data representing a 15-round jackpot opening pattern (corresponding to the first jackpot opening pattern) of the first jackpot 102. The 15-round jackpot release pattern covers 15 rounds, and for each round, the number of winning game balls to the first grand prize opening 102 is nine or the opening time of the first big prize opening 102 is 30 (seconds). ).

  On the other hand, if the determination in step 1230 is YES due to short wins, data representing the second big prize opening opening pattern is set in the second big prize opening opening pattern data set processing in step 1241. Here, the second grand prize opening opening pattern is opened for 0.1 (seconds) for each round over two rounds, and 0.1. It is set to close for 8 seconds.

  After the processing in step 1241, in the following latent table setting processing in step 1242, a short hit latency table for setting the short hit state is set. This short hit latency table is stored in advance in the ROM 380 as data representing the short hit release pattern of the first big winning opening 102, and the short hit latency table has two rounds. The opening time of the first big winning opening 102 is set to 0.5 (seconds) every round.

  On the other hand, when the determination in step 1220 is NO, it is determined in step 1240 whether or not a small hit is made. Here, the small win is the same as the above short win (2 round big win), it is a round of 2 rounds, and the opening time of the first big winning opening 102 becomes 0.5 (seconds) every round. It is. However, unlike the short win, the game state before the end is maintained as it is with the end of the small hit game.

  Therefore, when the determination in step 1240 is YES due to the small hit, in step 1241, data representing the second big prize opening opening pattern is set in the same manner as described above. Next, in the latent table setting process in step 1242, the small hitting latent table for setting the small hitting state is set. The small hit latency table is stored in advance in the ROM 380 as data representing the small hit release pattern of the first big winning opening 102. In the small hit latency table, the small hit latency table has 2 Over the rounds, the opening time of the first big prize opening 102 is set to 0.5 (seconds) every round. The small hit release pattern corresponds to the above-mentioned short hit pattern and an open pattern that does not correspond to the large acquisition of game balls.

  In step 1240, if it is not a small hit, it is determined as NO. Accordingly, in the reach selection random number setting process in step 1243, the latest random number of the reach random number data RNC set in step 622 of the start port processing routine 600 is selected and set as the reach selection random number. In the present embodiment, the reach is specified by a random value in the reach random number table TB3 (see FIG. 23C), for example, “7”.

  Next, in step 1250, it is determined whether or not it is reach. If the reach selection random number in step 1243 is “7”, it means reach, so that it is determined YES in step 1250, and then represents the reach mode in the reach table set processing in the next step 1251. A reach table is set. The reach table is stored in the ROM 380 in advance.

  On the other hand, if the reach selection random number in step 1243 is not “7”, the reach is not reach. Therefore, it is determined NO in step 1250, and in the process for setting the table for loss in step 1252, this indicates a loss mode. A table is set. The loss table is stored in the ROM 380 in advance.

  As described above, when one of the steps 1231, 1242, 1251, and 1252 is completed, the fluctuation in the random number update processing routine 500 (see FIG. 21) is performed in the fluctuation pattern selection random number setting process in the next step 1260. The latest random number of the pattern random number data RND is set as a random number for selecting a variation pattern.

  Then, in the next step 1270, variation pattern set processing is performed. Here, the variation pattern specified by the random number for variation pattern selection is set as a variation pattern for big hit, short hit, small hit or reach based on the variation pattern table. In the present embodiment, the variation pattern table includes each random number in the variation pattern random number data RND and each corresponding variation pattern corresponding to each random number (variation patterns for big hit, short hit, small hit and reach). And stored in the ROM 380 in advance.

  When the processing of the variation pattern selection processing subroutine 1200 is completed in this manner, variation start command set processing is performed in the next step 1300 (see FIG. 26). Accordingly, a variation start command for the variation pattern that has been set in step 1270 is set.

  Next, in the fluctuation start process in step 1310, main controller 300 drives special symbol display 140 by CPU 360 so as to display the fluctuation pattern set in step 1270. For this reason, the special symbol display device 140 performs variation display according to the variation pattern.

  After the process of step 1310, the measurement of the fluctuation time of the fluctuation pattern is started in the fluctuation time counting start process in step 1320. Here, the time of the fluctuation time is measured by a soft timer built in the main controller 300.

  Thereafter, when the special symbol processing routine 1000 proceeds to step 1020 again, if it is determined YES, in the next step 1400, it is determined whether or not the variation time is over. At the present stage, if the fluctuation time started in step 1320 has not yet reached the predetermined fluctuation time, the determination in step 1400 is NO.

  In such a state, when the special symbol processing routine 1000 again proceeds to step 1400, if the variation time started in step 1320 reaches the predetermined variation time, in step 1400, It is determined as YES. Then, in the change stop command setting process in step 1410, the change stop command is set so as to stop the change display of the change pattern started in step 1310.

  Next, in the fluctuation stop process in step 1420, main controller 300 causes CPU 360 to stop the fluctuation display of special symbol display 140 described above (see reference numeral 2a in FIG. 31). For this reason, the special symbol display device 140 stops the variation display by the variation pattern.

  After the process of step 1420, in the variable time reset process in step 1430, the predetermined variable time is reset, and the special symbol processing routine 1000 proceeds to the stopped processing subroutine 1500 (see FIGS. 26 and 29).

  In other words, in the special symbol processing routine 1000, after the determination of big hit or loss (see step 1120) is made, the determination of big hit, short hit, small hit or loss (see steps 1220, 1230, 1240) is made. The variation effect of the big hit, short hit, small hit or loss variation pattern set is made, and the stop processing subroutine 1500 is processed along with the stop.

  In this stop processing subroutine 1500, it is determined in step 1510 (see FIG. 29) whether or not it is a hit. Here, the winning means either a big hit or a short hit. At this stage, if the variation pattern set in step 1270 (refer to FIG. 28) is neither the big hit, short hit or small hit variation pattern, it is not a hit. It is determined. Then, in the next step 1520, it is determined whether J = 0. Here, J represents the number of changes in the special symbol during the short-time game. Note that the short-time game means that the special symbol variation time is shortened after the jackpot game with the non-probable variation game is finished and the opening time of the electric tulip 60b is extended, so that the player's ball is not reduced. A game that often changes special symbols.

  If J is not 0 at the present stage, it is determined as NO in step 1520, and then, in the next step 1521, the number of fluctuations J is subtracted and updated by “1” based on the following equation (10).

J = J-1 (10)
Next, in step 1530, it is determined again whether J = 0. At this stage, if J = 0 is not satisfied, NO is determined in step 1530. Thereafter, when the stop processing routine 1500 reaches step 1530 at least once, if J = 0, YES is determined in step 1530. As a result, the short-time game ends. Then, in the normal game state setting process in the next step 1531, the normal game state is set.

  In the above-described step 1510, when the variation pattern already set in step 1270 (see FIG. 28) is one of the variation patterns for big hit, short hit, and small hit, if YES is determined. In the next step 1540, it is determined whether or not it is a small hit. Here, if the variation pattern that has been set in step 1270 (see FIG. 28) is a variation pattern for small hits, this variation pattern for small hits corresponds to a small hit, so it is determined YES in step 1540, In the small hitting start command setting process in step 1541, a small hitting start command for outputting to the effect control unit 400b is set for the small hitting effect.

  Next, in step 1542, a small hit start process is performed. Here, the release process for the first attacker 100 and the second attacker 170 is performed as follows.

  The first attacker 100 is driven under the control of the CPU 360 based on the small hit latency table (see step 1242). That is, the movable member 101 of the first attacker 100 is controlled by the CPU 360 based on the small hitting latency table and is driven by the first big prize opening actuator 103 to open and close the first big prize opening 102. Then, it is performed according to the small hit release pattern of the small hit latent table. In other words, the first grand prize opening 102 is opened by 0.5 (seconds) for each round over two rounds. As a result, the game balls launched into the game area 12 as described above can easily win the first grand prize opening 102.

  Concurrently with the opening and closing of the first big prize opening 102, the second attacker 170 controls the CPU 360 based on the second big prize opening opening pattern data set in step 1241 (see FIG. 28). It is driven as follows. That is, the second big prize opening actuator 173 tilts the blade 170c to the left so as to open the second big prize opening 171 under the control of the CPU 360 based on the second big prize opening opening pattern data. .

  Thereafter, the second big prize opening actuator 173 tilts the blade 170c in a direction to close the second big prize opening 171. Such opening and closing of the second big prize opening 171 is repeated based on the second big prize opening opening pattern data. In other words, in the small hit game, the second big winning opening 171 is repeatedly opened at intervals of 0.8 (seconds) by 0.1 (seconds) over two rounds. As a result, there is a possibility that the game ball will win the second big winning opening 171.

  As described above, in the small hitting start process in step 1542, the second big winning opening 171 is changed to the second big winning prize 171 as the first big winning opening 102 is opened and closed according to the opening pattern for small hitting. Opened and closed according to the mouth opening pattern. As a result, the game ball is likely to win the second big prize opening 171 as it becomes easier to win the first big prize opening 102.

  In addition, in the small hitting start signal output processing in step 1543, a small hitting start signal indicating the start of the small hitting game is output to the sub-control device 400.

  On the other hand, in step 1540 described above, if the variation pattern already set in step 1270 (see FIG. 28) is either a big hit or short hit variation pattern, it is not a small hit, so it is determined as NO. . Accordingly, the in-stop processing routine 1500 proceeds to the next probability variation gaming state subroutine 1550 (see FIGS. 29 and 30).

  Then, in step 1551 (see FIG. 30), it is determined whether or not the probability variation symbol. At this stage, if the probability variation symbol that has been set in step 1132 (see FIG. 27) is the probability variation symbol, it is determined YES in step 1551, and then in the probability variation gaming state setting process in the next step 1552, The gaming state is set to the probable gaming state.

  If the determination in step 1551 is NO, it is determined in step 1553 whether or not the probability variation symbol. At this stage, if the probability variation symbol that has been set in step 1132 (see FIG. 27) is the probability variation symbol, it is determined YES in step 1553, and then the gaming state is determined in the time-short gaming state setting process in step 1554. , Set to the short-time gaming state. Accordingly, in the next step 1555, the number J of changes in the special symbol during the short-time game is set to J = 100.

  If the determination in step 1553 is NO, in the next step 1556, it is determined whether or not the game state is normal. At the current stage, if the gaming state is not the normal gaming state, after determining NO in step 1556, the processing in step 1552 is performed in the same manner as described above. If the determination in step 1556 is YES, the gaming state is set to the latent gaming state in the latent gaming state setting process in the next step 1557. Note that the latent game state is a state where a small hit game state is not notified.

  When the processing in step 1552, 1557, or 1555 is completed as described above, the stopped processing routine 1500 proceeds to step 1560 (see FIG. 29). Accordingly, in step 1560, a jackpot start command is set. Here, since the basis for the determination of NO in step 1540 is either the big hit or short hit variation pattern set in step 1270 (see FIG. 28) as described above, the big hit start command Is set as either a big hit or short win start command.

  Next, in the next step 1570, jackpot start processing is performed. Here, if the jackpot start command has already been set in step 1560 based on the determination result of NO in step 1540 described above, the processing in step 1570 determines that the jackpot game (15 round jackpot game) is described above. This is done to control the opening of the first attacker 100 according to the 15 round jackpot pattern. Also, if the short win start command has been set in step 1560, the processing in step 1570 determines that the short win game (two round jackpot game) is performed in the second big winning opening 102 according to the second big winning opening release pattern described above. Made to do with open control.

  In other words, as described above, when it is determined NO in step 1230 of the variation pattern selection processing subroutine 1200 and the jackpot table is set in step 1231, the stopped processing routine 1500 reaches step 1570. The first attacker 100 is driven under the control of the CPU 360 based on the jackpot table. That is, the movable member 101 of the first attacker 100 is controlled by the CPU 360 based on the 15 round jackpot release pattern of the jackpot table, and is driven by the first jackpot actuator 103 so that the first jackpot 102 Opening and closing is performed according to the above 15 round jackpot opening pattern. In other words, the first grand prize winning opening 102 is opened for 15 rounds, with 9 game balls being won or 30 seconds. As a result, the game balls launched into the game area 12 as described above can easily win the first grand prize opening 102. As a result, the player can have a chance to win a large number of prize balls.

  On the other hand, as described above, after it is determined YES in step 1230 of the variation pattern selection processing subroutine, the second big prize opening opening pattern data is set in step 1241 and the short hit latent table is set in step 1242. After that, when the in-stop processing routine 1500 reaches step 1570, the first attacker 100 is driven under the control of the CPU 360 based on the short hit latency table (see step 1242). That is, the movable member 101 of the first attacker 100 is controlled by the CPU 360 based on the short hit latency table and is driven by the first big prize opening actuator 103 to open and close the first big prize opening 102. In accordance with the short hit release pattern of the short hit latency table. In other words, the first grand prize opening 102 is opened by 0.5 (seconds) for each round over two rounds. As a result, the game balls launched into the game area 12 as described above can easily win the first grand prize opening 102.

  In parallel with the opening and closing of the first big prize opening 102, the second attacker 170 makes the second big prize opening 171 of the second attacker 170 the same as the processing in step 1542. Open and closed based on the second big prize opening opening pattern data set in (see). In other words, even in the short win game, the second grand prize winning opening 171 is opened by 0.5 (seconds) for two rounds. As a result, there is a possibility that the game ball will win the second big winning opening 171.

  As described above, in the jackpot start process in step 1570, the first jackpot 102 is opened and closed according to the jackpot opening pattern. Alternatively, as the first big prize opening 102 is opened and closed according to the short hit opening pattern, the second big prize opening 171 is opened and closed according to the second big prize opening pattern. As a result, the game ball is likely to win the second big prize opening 171 as it becomes easier to win the first big prize opening 102.

After the processing of step 1570 described above, in the jackpot start signal output processing in the next step 1580, a jackpot start signal indicating the start of either jackpot game, in other words, jackpot game or short hit game is output to the sub-control device 400. Is done.
(6) Normal symbol processing When the processing of the special symbol processing routine 1000 is completed as described above, the timer interrupt program proceeds to the normal symbol processing routine 2000 (see FIGS. 21 and 31). Then, in step 2100 (see FIG. 31), it is determined whether or not an auxiliary game is being performed. At the present stage, if the auxiliary game is being performed, the determination in step 2100 is YES.

  On the other hand, if the auxiliary game is not being performed, it is determined as NO in step 2100, and then in step 2200, it is determined whether or not the game is changing.

  If the normal symbol is not changing at the present stage, it is determined in step 2300 whether G ≧ 1 after determining NO in step 2200. Here, if the number G of game balls held for the latest through gate 70 in step 721 (see FIG. 25) is G = 0, the determination in step 2300 is NO. On the other hand, if G ≧ 1 is established, it is determined YES in Step 2300, and then, in Step 2310, the hold number G is updated by subtraction by “1” based on the following equation (11).

G = G−1 (11)
Thereafter, in the winning lottery random number setting process in step 2311, the latest random number of the winning random number data RNE in the random number update processing routine 500 (see FIG. 21) is set as the winning lottery random number.

  Next, in step 2320, it is determined whether or not it is a hit. If the current stage is a win, the determination in step 2320 is YES, and the win symbol is set in the win symbol set process in the next step 2321. If the determination in step 2320 is NO, the lost symbol is set in the lost symbol setting process in step 2322.

  After the processing in step 2321 or 2322, it is determined in step 2330 whether or not the game state is probable or time-saving. At this stage, if the game state is one of probability change and time saving, it is determined YES in Step 2330, and then in Step 2331, the variation time is set to 3 (seconds). On the other hand, when the determination in step 2330 is NO, in step 2332, the variation time is set to 29 (seconds).

  After the processing of step 2331 or step 2332 is performed in this way, in the fluctuation start processing in step 2333, the normal symbol display unit 130 causes the winning symbol set in step 2321 or the symbol set in step 2322 to be set. The display of the variation of the lost symbol is started. Accordingly, in the variable time counting start process in step 2334, the soft timer built in main controller 300 is reset to start timing.

  Thereafter, when the normal symbol processing routine 2000 proceeds to step 2200 again, since the fluctuation has already been started in step 2333, it is determined as YES in step 2200. Then, in step 2340, it is determined whether or not the variable time is over. Here, if the time measured by the soft timer that has already started counting in step 2334 has not reached the predetermined fluctuation time, the determination in step 2340 is NO.

  In this state, when the normal symbol processing routine 2000 again proceeds to step 2340, if the time measured by the soft timer that has already started time counting in step 2334 has reached the predetermined fluctuation time, YES is determined in step 2340. Determined. Accordingly, in the fluctuation stop process in step 2341, the fluctuation of the winning symbol or the lost symbol started in step 2333 is stopped in the normal symbol display 130. In step 2342, the variation time is reset.

Thereafter, in the next step 2400, it is determined whether or not it is a hit. If it is not a hit, the determination in step 2400 is NO. On the other hand, when the determination in step 2400 is YES, the auxiliary game is started in the auxiliary game start process in step 2410.
(7) Grand prize opening processing When the processing of the normal symbol processing routine 1000 is completed as described above, the timer interruption program proceeds to the big winning mouth processing routine 3000 (see FIGS. 21 and 32 to 34).

  In the big prize opening processing routine 3000, the big hit time release processing routine 3100 is generally the first big one until the establishment of the round number R = upper limit value (for example, 15) through the opening effect at the start of the big hit game. By repeatedly opening and closing the winning opening 102, the player is provided with an opportunity to acquire a large prize ball (see FIG. 33).

  In addition, the small-hit opening processing subroutine 3200 is generally performed by opening the first big winning opening 102 and closing it with the end of the opening effect at the start of the big-hit game. It is configured to give an opportunity to acquire a prize ball (see FIG. 34).

  Hereinafter, each process of the big hit release processing routine 3100 and the small hit release processing subroutine 3200 will be sequentially described in detail.

  In the jackpot release processing subroutine 3100 (see FIG. 33), it is determined in step 3110 whether or not the jackpot is being hit. At this stage, if it is not a big hit, NO is determined at step 3110. On the other hand, if it is a big hit, the determination in step 3110 is YES.

  When the determination in step 3110 is YES because of the big hit, the next step 3120 determines whether or not the opening is in progress. Here, the opening refers to an opening effect that represents the start of the jackpot game with the start of the jackpot game. At the present stage, if the opening is being performed, YES is determined in step 3120, and in step 3130, it is determined whether or not the opening time has elapsed. If the predetermined opening time has not yet elapsed at the present stage, the determination in step 3130 is NO. The predetermined opening time is measured by a soft timer built in main controller 300.

  When the jackpot release processing subroutine 3100 proceeds to step 3130 at least once after determining NO in step 3130, if the predetermined opening time has elapsed, YES is determined in step 3130. The Then, in the next step 3131, the round number R is added and updated based on the following equation (12).

R = R + 1 (12)
When the processing in step 3131 is completed in this way, in the first big prize opening opening process in the next step 3132, the first attacker 100 controls the first member 100 in the movable member 101 under the control of the CPU 360. Driven by the actuator 103, the first big prize opening 102 is opened. As a result, the game balls launched into the game area 12 as described above can easily win the first big prize opening 102. As a result, the player can expect to win many prize balls.

  After step 3132, it is determined in step 3140 whether the open time has elapsed. At the present stage, if the predetermined opening time for the first big prize opening 102 has not yet elapsed, NO is determined in step 3140. In the present embodiment, during the above-described predetermined opening time, the soft timer built in the main control device 300 is reset and starts counting the opening time.

  With the determination of NO in step 3140, in the next step 3150, it is determined whether or not C ≧ upper limit value (for example, 9). Here, in C ≧ upper limit value, C means the number of winning game balls to the first big winning opening 102. At this stage, if the winning number C has not reached the upper limit, the determination in step 3150 is NO.

  Thereafter, when the jackpot opening process subroutine 3100 proceeds to step 3140 at least once, if the opening time for the first big prize opening 102 has elapsed, the above-mentioned predetermined time by the above-mentioned soft timer is reached. It is determined YES based on the time measurement result for the opening time. If YES in step 3140 and the number C of winning prizes reaches the upper limit, YES is determined in step 3150.

  Thus, if the determination in step 3140 or step 3150 is YES, in the first big prize opening closing process in the next step 3151, the first attacker 100 is controlled by the movable member 101 under the control of the CPU 360. Driven by the first grand prize opening actuator 103, the first big prize opening 102 is closed.

  After the processing of step 3151, it is determined in step 3160 whether R = the upper limit number of times. In the present embodiment, since it is a jackpot game, the upper limit number of rounds is 15 in 15 round jackpots or 2 in 2 round jackpots (short hit). At this stage, if R <the upper limit number of times, NO is determined in step 3160.

  Thereafter, when the jackpot release processing subroutine 3100 reaches step 3160 at least once, if R = the upper limit number of times, YES is determined based on the latest update round number R in step 3131. The This means that the current jackpot game, in other words, the 15-round jackpot or short win game has ended.

  Accordingly, after the round number R = 0 is cleared in the next step 3161, in the ending process in step 3162, a process of starting an ending effect indicating the end of jackpot is started on the image display 50 as described later. . Note that this ending effect time, that is, a predetermined ending time is counted by a soft timer built in the main control device 300.

  At the present stage, since the predetermined ending time has not elapsed, NO is determined in step 3170. Thereafter, when the jackpot opening process subroutine 3100 proceeds to step 3120 again, since the opening effect has already ended at this stage, it is determined as NO in step 3120. Then, in step 3190, it is determined whether or not it is open. At the present stage, as described above, the first big winning opening 102 is already closed for the end of the jackpot game, and therefore, it is determined NO in step 3190 based on the determination of YES in step 3160 described above. The

  Accordingly, it is determined in step 3190a whether or not ending is in progress. Here, if it is during the above-mentioned ending effect, after determining with YES in step 3190a, the determination in step 3170 will be performed. On the other hand, if the above-mentioned ending effect has been completed, it is determined NO in step 3190a, and then it is determined in step 3190b whether or not the interval time has elapsed. In the present embodiment, the interval time refers to a predetermined elapsed time between rounds, that is, a time until the first big prize opening 102 is opened after being closed. The predetermined elapsed time is counted by a soft timer built in main controller 300.

  Thus, if the current stage is before the determination of YES in step 3160 described above, if the predetermined elapsed time has not elapsed, NO is determined in step 3190b. Thereafter, if the predetermined elapsed time has elapsed when the jackpot release processing subroutine 3100 reaches step 3190b at least once or more, the step is performed based on the result of counting the predetermined elapsed time by the soft timer. In 3190b, it is determined YES. Accordingly, in step 3130, the round number R is added and updated based on the equation (12). Note that the addition update processing in step 3131 is repeated 15 times or twice after the determination of YES in step 3130 and after each determination of YES in step 3190b after this determination.

  Thus, when the jackpot release processing subroutine 3100 advances to step 3190a, if the ending is in progress after the end of the jackpot game 15 times or twice, the determination in this step becomes YES, and in the next step 3170 Whether or not the ending time has elapsed is determined. Here, if the answer is YES based on the result of counting the predetermined ending time by the soft timer, the jackpot game is ended in the next jackpot game end subroutine 3180. Accordingly, the processing of the next small hitting time opening processing subroutine 3200 is performed as follows according to the flowchart of FIG.

  In the small hit release process subroutine 3200, it is determined in step 3210 (see FIG. 34) whether or not opening is in progress. In the present embodiment, the opening refers to an opening effect that is made with the start of a small hit game. Here, if it is during opening, YES is determined in step 3210. Accordingly, in the next step 3220, it is determined whether or not the opening time has elapsed. Here, the opening time is measured by a soft timer built in main controller 300 as a predetermined opening time.

  At the present stage, since the predetermined opening time has not elapsed, the determination at step 3220 is NO. After that, when the small hitting time opening process subroutine 3200 reaches step 3220 at least once, if the predetermined opening time has elapsed, based on the timing result of the predetermined opening time by the soft timer, In step 3220, it is determined as YES.

  Accordingly, in the big winning opening opening process in the next step 3221, the first attacker 100 is controlled by the CPU 360 with the movable member 101 under the control of the CPU 360 as in the case of the short hit. To open the first big prize opening 102.

  Thus, after the processing in step 3221 is completed, it is determined in next step 3230 whether or not the open time has elapsed. In the present embodiment, the opening time is measured by a soft timer built in the main control device 300 as a predetermined opening time for small hits of the first big winning opening 102. At the present stage, since the predetermined opening time has not yet elapsed, it is determined in step 3230 that NO, and then in the next step 3240, it is determined whether C ≧ 9. Here, if the number C of winnings based on the above-mentioned opening of the first big winning opening 102 in the small hit game is less than 9, it is determined NO in Step 3240.

  After that, when the small hitting time opening process subroutine 3200 reaches step 3230 at least once, if it is determined YES before the determination of YES in step 3240, the big prize opening closing process in step 3241 is performed. Is made. If YES is determined in step 3240 before YES is determined in step 3230, the big prize opening closing process in step 3241 is similarly performed. Accordingly, the first attacker 100 is driven by the first big prize opening actuator 103 by the movable member 101 under the control of the CPU 360 to close the first big prize opening 102.

  Thus, after the process in step 3241 is finished, in the ending start process in the next step 3242, the image display displays the effects until the start of the next fluctuation after the actual small hit game with the closing of the first big winning opening 102. A process to start at 50 is performed.

  Thereafter, it is determined in step 3250 whether or not the ending time has elapsed. In the present embodiment, the ending effect time, that is, the predetermined ending time is measured by a soft timer built in the main controller 300.

  At the present stage, since the predetermined ending time has not yet elapsed, the determination in step 250 is NO. When the small hitting time release processing routine 3200 proceeds to step 3210 again, it is determined NO because the above-described opening effect has already been completed. Next, in step 3211, it is determined whether or not ending is in progress. Here, if it is during the ending effect in the image display 50, since it is ending, it determines with YES in step 3211. Here, “in ending” means that the effect processing by the image display device 50 is in the effect processing from the end of the small hit to the start of the next fluctuation.

Thereafter, when the small hitting time release processing routine 3200 proceeds to step 3250 through step 3211 at least once or more, if the predetermined ending time has elapsed, based on the timing result of the soft timer. After the determination at step 3250 is YES, in the next small hit game end processing subroutine 3260, the image display unit 50 performs a process for ending the ending effect. If the determination in step 3211 is NO, both steps 3230 and 3240 sequentially determine NO.
(8) Electric Chu Processing When the processing of the special winning opening processing routine 3000 is completed as described above, the timer interruption program proceeds to the next electric chew processing routine 4000 (see FIGS. 21 and 35). In this electric chew processing routine, when the gaming state of the pachinko gaming machine is in the auxiliary game, the electric tulip 60b is released according to the gaming state of the probability change or the short time after the opening effect is finished, so that the electric prize is given to the player. The chance of winning a game ball to the mouth 62 is increased. Details will be described below.

  As described above, when the timer interruption program proceeds to the electric chew processing routine 4000, it is determined in step 4100 (see FIG. 36) whether or not an auxiliary game is in progress. At the present stage, if the gaming state by the pachinko gaming machine is in an auxiliary game, the determination in step 4100 is YES.

  Then, in the next step 4200, it is determined whether or not opening is in progress. Here, “opening” means that an opening effect is being made on the image display 50 with the start of the auxiliary game. Therefore, at the present stage, if the opening effect is accompanied by the start of the auxiliary game, it is determined YES in step 4200, and then in step 4300, it is determined whether or not the opening time has elapsed. Here, the progress of the opening is determined by the passage of a predetermined opening time. If the predetermined opening time has not yet elapsed at the present stage, the determination in step 4300 is NO. Note that the lapse of the opening time is determined based on the result of counting the predetermined opening time by a soft timer built in main controller 300.

  After that, when the electric chew processing routine 4000 reaches step 4300 at least once, if YES is determined, it is determined in the next step 4400 whether the game state is probable or short.

  Thus, if the gaming state is a promising or short-time gaming state at the present stage, it is determined YES in Step 4400, and then the opening time of the electric tulip 60b in the next opening time setting process in Step 4410 is 3. Set to 5 (seconds). On the other hand, if the game state is not a probability change or a short-time game state but a non-probability change game state (normal game state), the release time of the electric tulip 60b is 0.2 (seconds) in the release time setting process in step 4420. Set to

  After the processing in step 4410 or 4420, in the next electric chew release processing in step 4430, the electric tulip 60b is controlled to 3.5 (seconds) or 0.2 (seconds) under the control of the CPU 360 of the main controller 300. During this time, it is driven and opened by the start opening actuator 63. Along with this, the electric winning opening 62 of the electric tulip 60b is opened. Thereby, the player can expect an increase in the winning of the game ball to the electric winning opening 62 via the electric tulip 60b.

  After the processing in step 4430, it is determined in step 4500 whether or not the opening time has elapsed. Accordingly, if the opening time of the electric tulip 60b has not elapsed for the predetermined opening time, it is determined as NO in Step 4500. It should be noted that the elapse of the opening time of the electric tulip 60b is made by counting the predetermined opening time by a soft timer built in the main control device 300.

Thereafter, when the predetermined opening time has elapsed when the electric chew processing routine 4000 reaches step 4500 at least once or more, in step 4500, the predetermined opening time of the predetermined time by the soft timer is reached. It is determined YES based on the time measurement result. Accordingly, in the electric chew closing process in step 4510, the electric tulip 60 b is driven by the start opening actuator 63 under the control of the CPU 360 of the main controller 300, and a game ball wins the electric winning opening 62. Close to regulate. Accordingly, in the auxiliary game end process in step 4520, the auxiliary game by the pachinko gaming machine is ended.
(9) Output Processing When the processing of the electric chew processing routine 3000 is completed as described above, the timer interruption program proceeds to the output processing routine 5000 (see FIG. 21). In this output processing routine 5000, the detection output of the electric chew sensor S2, the detection output of the normal winning mouth sensor S4, and the first big winning mouth sensor S5 performed in each processing of the random number update processing routine 500 to the electric chew processing routine 400. The detection output and other various data are output to the sub-control device 400.
3. Sub-control-device-side game operation mode When the main-control-device-side game operation mode is processed as described above, in the sub-control device 400, the payout control unit 400a is placed in the payout game operation mode and the effect control unit 400b. However, together with the display control unit 400c and the lamp control unit 400d, the production game operation mode is set.
(1) Payout Game Operation Mode After the payout control unit 400a of the sub control device 400 starts executing the payout control program as described above, various data are transferred from the main control device 400 to the output processing routine 5000 as described above. When output to the control device 400, if the various data includes payout data (detection output of the first big prize port sensor S5 or detection output of the second big prize port sensor S6), the payout control unit 400a The CPU 413 inputs the payout data via the I / F 411 to perform payout processing of the game ball, and outputs a payout output from the O / F 412 to the payout drive motor M. Therefore, the payout mechanism pays out the game ball in accordance with a predetermined payout condition under the drive of the payout drive motor M.
(2) Effect Game Operation Mode As described above, when the effect control unit 400b of the sub-control device 400 starts executing the effect control program according to the flowchart of FIG. 36, in the random number update processing routine 7000, various effects such as effect random numbers are generated. The random number is updated based on various random number data such as rendering random number data stored in the ROM 426. In the present embodiment, the above-described production random number data includes both a low-probability gaming state in which the jackpot winning probability in the jackpot lottery is a normal probability and a high-probability gaming state in which the winning probability is higher than the normal probability. Is a data required for performing a lottery to notify or conceal any of the gaming states, and is composed of a random number sequence consisting of 0, 1, 2,.
(1) Various Input Processing When the processing of the random number update processing routine 7000 is completed as described above, the effect control program proceeds to various input processing routines 8000 (see FIGS. 36 and 37). Then, in the game state information set process in step 8100 (see FIG. 27), various game state information among the various data output from the main control device 300 as described above is the O / F 350, I / F 421, and bus. The data is input to the CPU 425 through the line 420 and set in the RAM 427 by the CPU 425.

  Next, in step 8200, it is determined whether the game is a small hit or a short hit. Here, based on the small hitting start signal output from main controller 400 in step 1543 (see FIG. 29) or the big hit starting signal output from main controller 400 in step 1580 as described above, in step 8200, It is determined as YES. If it is not a small hit or short hit, NO is determined in step 8200.

  If YES is determined in step 8200 as described above, the detection output of the second prize winning port sensor S6 is in an effective state in the second prize winning sensor detection function validation process in the next step 8210. This means that the notification lottery symbol variation function is activated. Next, in step 8300, it is determined whether or not the notification lottery is executed. In this embodiment, the notification lottery execution determination is made based on the detection output of the second grand prize port sensor S6. This means that the second big prize opening sensor S6 also serves as a notification lottery sensor. For this reason, there is no need to separately provide a notification lottery sensor.

  At the present stage, when the second big prize opening 171 is opened in the main controller side game operation mode as described above, when the game ball wins the second big prize opening 175, the game ball becomes the second attacker. It falls into the communication path 171a of 170, and is detected as a notification lottery by the second grand prize port sensor S6. For this reason, since this detection corresponds to notification lottery execution, it is determined as YES in Step 8300 based on the detection output of the second big prize winning port sensor S6.

  Thereafter, in step 8400, it is determined whether K <2. Here, K represents the number of game balls won in the second grand prize winning port 171, in other words, the number of game balls held as a basis for executing the notification lottery. At this stage, if K = 0 has been cleared in step 8420, YES is determined in step 8400 based on K = 0. Then, in the next step 8410, based on K = 0 from the following formula (13), K = 1 is added and updated. This means that the number of reserved game balls that is the basis for the notification lottery at the current stage is “1”. In the present embodiment, the hold number K (hereinafter also referred to as a hold storage number K) is stored in the RAM 427 of the arithmetic control unit 400b for each addition and update.

K = K + 1 (13)
Next, in the effect random number setting subroutine 8500, the latest random number of the effect random number data updated in the random number update processing routine 7000 is set in the RAM 427 by the CPU 425. Thereafter, in step 8600, it is determined whether or not the second big prize opening is closed. If the second big prize opening 171 is in the open state at the present stage, the second big prize opening 171 is not closed, so that it is determined as NO in Step 8600.

  Thereafter, when the game ball newly wins the second grand prize port 171, the game ball is newly detected by the second big prize port sensor S 6. For this reason, YES is determined in step 8300. At this stage, since K = 1, YES is determined in step 8400, and in step 8410, K = 2 is added and updated based on K = 1 based on K = 1. In the effect random number setting subroutine 8500, the latest effect random number is set in the same manner as described above.

  In such a stage, if the second big prize winning opening 171 is in the open state, it is determined NO in Step 8600, and then a new determination process in Step 8300 is performed again. Here, when the game ball newly wins the second big prize opening 171 again, this game ball is detected by the second big prize opening sensor S6. Accordingly, after the determination at step 8300 is YES as described above, the determination at step 8400 is YES based on K = 2. In the next step 8410, k = 3 is added and updated based on K = 2 based on K = 2, and in the effect random number setting subroutine 8500, the latest effect random number is set as described above. Thereafter, when the various input processing routine 8000 proceeds to step 8400, it is determined as NO because K = 3 already. This means that the upper limit value of the notice lottery hold number is two.

  Thus, after the processing in step 8420 as described above, or after it is determined YES in step 8600 based on the closing of the second prize winning opening 171, display control is performed in various input reading processing in the next step 8700. Various input data such as a symbol pattern from the section 400 c and a lamp pattern from the lamp control section 400 d are read by the CPU 425 and set in the RAM 427.

When the reserved storage number K is updated in step 8410 of each input display processing routine 8000, the display control unit 400c causes the CPU 433 to display each notification lottery symbol holding lamp according to the value of the updated reserved storage number K. Turn on 190. Thereby, the player can visually recognize the number of holds for the notification lottery.
(2) Display Processing When the processing of the various input processing routines 8000 is completed as described above, the processing of the next display processing routine 9000 (see FIGS. 36 and 38) is performed. Therefore, in the special symbol-corresponding decorative symbol processing subroutine 9100 (see FIG. 38), the data related to the special symbol among the various data output as described above from the main controller 300 in the output processing routine 5000 (see FIG. 21). Based on this, the process of setting the decorative design corresponding to the special design is performed.

  Thereafter, in the jackpot game display processing subroutine 9200, an effect display process representing the jackpot game is performed based on the data representing the jackpot among the various data output as described above. Accordingly, based on the display processing, the image display 50 is driven by the display control unit 400c to display the effect representing the above jackpot game, and the frame lamp LP, each star board lamp 120, and each The star-shaped movable accessory 120 is driven by the lamp control unit 400c, and displays a lighting effect in accordance with the effect display represented during the jackpot game by the image display 50 described above.

  When the processing of the jackpot gaming display processing subroutine 9200 is completed in this way, in the other standby display processing subroutine 9300, the standby status is displayed based on the data indicating the standby status among the various data output as described above. An effect display process is performed. Accordingly, based on the display processing, the image display device 50 is driven by the display control unit 400c to display an effect representing the above-described standby, etc., and the frame lamp LP, each star board lamp 120, and each The star-shaped movable accessory 120 is driven by the lamp control unit 400c to display a lighting effect in accordance with the effect display indicating that the image display device 50 is on standby.

  When the other standby display processing subroutine 9300 is completed as described above, the display processing routine 9000 proceeds to the next notification lottery display processing subroutine 9400 (see FIG. 38).

  Therefore, in the notification lottery display processing subroutine 9400, the notification lottery processing is repeated on the assumption that the latest reserved storage number K in step 8410 in the various input processing routines 8000 (see FIG. 37) is K ≧ 1. . When the result of the notification lottery is a win or a loss, the notification lottery symbol display 180 displays a variation of the win or lose under the control of the display control unit 400c. Thereafter, in the notification lottery result notification process, when the notification lottery result is successful, the notification lottery symbol display 180 notifies a high probability or a low probability under the control of the display control unit 400c. On the other hand, when the notification lottery result is a loss, the notification lottery symbol display 180 notifies the loss under the control of the display control unit 400c.

  As described above, in the present embodiment, each time a game ball is guided into the game area 12 sequentially through the guide passage portion 11a of the guide rail 20 in the game process of the player by the pachinko gaming machine, The game ball collides with the ball stopper piece 260 of the ball return prevention device 200 from below. Then, at each collision, the ball stop piece 260 tilts from the tilt position shown in FIG. 17 toward the tilt position shown in FIG. 18 against the dead weight of the weight 250. Accordingly, each game ball that collides with the ball stopper piece 260 is guided into the game area 12.

  In this way, as each game ball is sequentially guided into the game area 12 through the guide passage portion 11a, the ball stopper piece 260 of the ball return prevention device 200 is caused to collide with the game ball as described above. Even if the tilting is repeated, the ball return prevention device 200 is firmly assembled to the one end portion 21 of the inner rail portion 20a as described above. The above-described assembled state with respect to the side distal end portion 21 can be satisfactorily maintained without being affected by repeated collision of the ball stopper piece 260 with the game ball and without causing any positional deviation.

  In addition, the game ball guided to the game area 12 as described above is repelled by the collision with the blade 172 in the closed state of the second attacker 170, or is repelled by any of the game nails 42. Thus, even when trying to return between the inner rail portion 20a and the outer rail portion 20b, if the ball stopper piece 260 of the ball return prevention device 200 is in the tilted state shown in FIG. 9 or FIG. The ball is stopped by the ball stop piece 260 and returned to the game area 12. Therefore, the game ball bounced as described above does not return into the guide passage portion 11a between the inner rail portion 20a and the outer rail portion 20b.

  Further, when removing the ball return prevention device 200 from the one side tip portion 21 of the inner rail portion 20a, for example, the tip portion of the minus driver is placed between the elastic piece main body 222 and the one side tip portion 21 of the elastic piece 220c. If the elastic piece main body 222 is bent to the side opposite to the one-side tip portion 21 by being inserted, the first projecting portion 223 of the elastic piece 220c can be dissociated from the one-side tip portion 21. In such a state, if the ball return prevention device 200 is pulled from the one side tip portion 21 of the inner rail portion 20a toward the front of the game board 10, it is close to the vicinity of the upper side of the one side tip portion 21 and other neighborhoods. The ball return prevention device 200 can be smoothly removed from the one end portion 21 of the inner rail portion 20a without being obstructed by the respective game balls 42. When a new ball return prevention device is assembled to the one end portion 21 of the inner rail portion 20a instead of the above-described ball return prevention device 200, the assembly may be performed in the same manner as described above.

In carrying out the present invention, the following various modifications are possible without being limited to the above embodiment.
(1) In carrying out the present invention, unlike the above embodiment, the ball return prevention device 200 is configured integrally with a plate frame 210 of the main member 200a and a cover plate 230 of the sub member 200b as a plate-like device body. In addition, even if the L-shaped wall 220a and the side wall 220b of the main member 200a and the U-shaped wall 240a of the sub member 200b are configured as a plate, the same effect as the above embodiment is achieved. Can do.

Here, unlike the said embodiment, the side wall part 220b WHEREIN: At least one of the L-shaped wall 220a and the U-shaped wall 240a may be united with the side wall 220b in the said board.
