Description

  The present invention relates to a pachinko gaming machine, and more particularly to an improvement of a pachinko gaming machine including a variable winning device that operates when a specific condition is satisfied, and a large-area display arranged on the back side of the variable winning device. It is.

  2. Description of the Related Art Pachinko machines equipped with a movable prize device having a movable surface component called a feather are conventionally known. The wings are composed of a pair of wings (movable pieces) that are rotated by using a solenoid as a driving source, and when a game ball wins a predetermined start winning opening, the solenoid is operated to turn the pair of wings once or two. By opening and closing about several times, the game ball flowing down the game board surface is captured and guided into the variable winning device.

In the conventional blades disclosed in Patent Documents 1 to 5, since the two blades are arranged close to each other, the opening and closing operation is generally performed by a drive mechanism using one solenoid as a drive source. is there.
That is, FIGS. 12A and 12B show a configuration example in the case where two blades are simultaneously opened and closed by one solenoid, and the two blades 200 have their base ends vertically and horizontally by a support member (not shown). The shaft is pivotally supported. A rotating shaft 201 projects integrally from the base end of each blade toward the rear. The rotating shaft 201 includes a rotating shaft main body 201a, a crank connecting member 201b that fixes the rotating shaft main body 201a to one end, and an engaging shaft 201c that protrudes rearward from the other end of the crank connecting member 201b. Have.

  On the other hand, the solenoid 210 includes a solenoid main body 211 fixed to another support member, and a plunger 212 supported so as to protrude downward from below the solenoid main body 211. A continuous arm 213 extending left and right from the tip of the plunger 212 is connected to a spring 214, and the plunger 212 is projected and biased downward by the spring. Engagement shafts 201c constituting each rotation shaft 201 are loosely fitted in elongated holes 213a provided at both ends of the continuous arm 213. Further, the other end portions of the two lock pieces 215 whose one end portions are pivotally supported by a support member that supports the solenoid 210 are rotatably connected to both end portions of the connecting arm 213.

In the above configuration, when the solenoid 211 is not energized as shown in FIG. 12A, the plunger 212 and the connecting arm 213 protrude downward by the spring 214. At this time, each blade 200 is in a closed state. Is maintained.
On the other hand, when the solenoid body 211 is energized as shown in (b), the plunger 212 and the connecting arm 213 are raised against the spring 214 to open each blade 200.
In this conventional example, since the two blades are arranged close to each other, a single solenoid as a drive source is arranged in the middle and rear position of both blades, and concealed so that it cannot be seen from the front. It was possible.

However, depending on the configuration of the movable prize-winning device, the two blades may be further separated from each other. In this case, when two blades are driven by one solenoid, each blade is branched from this solenoid. The structure of the driving force transmission mechanism connected to the cylinder is complicated and may increase in size. In addition, when a large liquid crystal display is arranged behind a space formed between two spaced apart blades, a single solenoid is arranged at a predetermined position avoiding the display, and a driving force transmission mechanism is installed in each position. Although it is necessary to consider branching toward the blades and preventing the wiring from being seen from the front, the layout may become extremely difficult. Further, since the two blades are driven by a single solenoid, there is a problem that the durability of the solenoid is lowered.

A mechanical mechanism plate (not shown) is mounted so as to be freely opened and closed.
Around the game area 1a of the game board 1, the game ball launched from the hitting ball launching handle 8 is guided to the upper part of the game area 1a, or as a game ball guide rail that guides to an unillustrated out-ball collection port. A rail R1 and an inner rail R2 are provided.

As shown in the exploded perspective view of FIG. 3, the variable prize-winning device 2 includes a front unit 11 that includes two rotatable blade members 20 that are spaced apart from each other in order to distribute game balls that are about to enter the inside. And a rear unit 30 that is disposed on the back side of the front unit 11 and includes a blade member driving mechanism 40 that drives each blade member 20. A display unit 50 having a large-area display 51 is assembled on the back side of the rear unit 30.
The front unit 11 is arranged in the back of a stage 12 provided on the inner bottom of the frame 12 and the shape of a specific character (Ultra Seven). The gimmick 14, the sorting member (rotary body) 15 rotatably supported on both sides of the gimmick 14, and the two shoulder portions 16 a of the frame body 16 provided above the stage 13 respectively rotate in the horizontal and vertical directions. It has two blade members 20 that are pivotally supported, a drive mechanism 17 such as a motor that drives the gimmick 14 and the sorting member 15, and the like.

A winning detection switch 25 for counting the number of winning balls by detecting the entering of a big winning opening located below each blade member 20 is arranged at an appropriate position on the winning path, and the counted entering balls The number of prize balls to be paid out is calculated based on the number. The discharge number count switch is arranged in the discharge path from the special winning opening, and counts the number of discharged balls. A control means (not shown) determines whether or not there is a clogged ball in the special winning opening based on the number of winning balls and the number of discharged balls. The entry into the specific area detection switch 26 is a main opportunity for winning a jackpot.
The rotation shaft 21 of each blade member 20 protrudes rearward, engages with a blade member drive mechanism 40 provided on the rear unit 30 side, and receives a driving force.

Between the two blade members 20 supported by the shoulder portion 16a of the frame body 16, a translucent area 18 is provided for making the display 51 located on the back side visible from the front. The translucent area 18 is constituted by a transparent plastic plate.
The rear unit 30 includes a frame body 31 having a configuration that can be assembled to the rear portion of the front unit 11. Specifically, bolts are fixed in place with the bottom of the frame 31 mounted on the upper surface of the drive mechanism 17 protruding rearward of the front unit 11. A rod 32 supporting a part (glasses) 33 of a character at the lower end is supported by a box 32 provided on the upper portion of the frame 31 so as to be movable up and down, and is driven up and down by a driving force from a motor 35.

Solenoids 36 are fixed vertically on both side walls 31a of the frame 31, and a plunger 36b is projected and retracted downward from the solenoid body 36a. Each plunger 36b is urged so as to always protrude downward by a spring.
In other words, the blade member driving mechanism 40 has a bifurcated branch portion (clamping piece) 41 a that holds and holds the rotating shaft 21 protruding backward from each blade member 20 at the tip, and the frame portion 31 moves the intermediate portion 41 b up and down. The two operating pieces 41 that are pivotally supported in the direction of rotation, and the plungers 36b supported by the frame body 31 are engaged with the base end portions of the respective operating pieces, and each of the operating pieces 41 is interlocked with the protruding and entering operation of each plunger. And two solenoids 36 for rotating the operating piece.

The rotating shaft 21 extending from each blade member 20 includes a rotating shaft main body 21a, a crank connecting member 21b having one end fixed to the rear end of the rotating shaft main body 21a, and the other end of the crank connecting member 21b. And an engagement shaft 21c projecting rearward. Thus, the rotating shaft 21 constitutes a crankshaft as a whole.
When the rear unit 30 is assembled to the front unit 11, the engagement shafts 21 c are loosely fitted into the branch portions of the bifurcated branch portions 41 a of the operating pieces 41. In this state, each rotary shaft 21 rotates by moving each operating piece 41 up and down around the intermediate portion 41b, so that each blade member 20 integrated with each rotary shaft opens and closes.

FIG. 7 is an explanatory diagram showing a specific configuration and operation of the blade member drive mechanism 40.
When the solenoid 36 is not energized, each plunger 36b protrudes downward by the spring, so that each operating piece 41 is biased upward at the bifurcated branch 41a at the tip (FIG. 7). (A)). At this time, the left and right blade members 20 are closed.
On the other hand, when each plunger retracts upward against the spring by energizing the solenoid, each actuating piece 41 is in a state where the tip end portion is inclined downward (FIG. 7B). At this time, the left and right blade members 20 are opened.
In the state where the blade member 20 is closed as shown in FIG. 4, the game balls that have been launched into the game area 1a and flowed down cannot enter the variable winning device 2, but the blade member is opened as shown in FIG. In this state, the game ball B can enter the variable winning device 2 through a route as indicated by an arrow.

  In the present invention, the display unit 50 having the large display 51 is assembled on the back side of the variable prize apparatus 2 so that the two blade members 20 provided in the variable prize apparatus 2 are arranged as far as possible outside the display 51. There is a need to. For this reason, the interval between the two blade members 20 is in an expanded state. If the two blade members 20 that are so separated from each other are driven by a single solenoid, they must be arranged at the center of the front side of the display 51. In such a configuration, the surface of the display is wide. The area is obscured by the solenoid and the meaning of placing a large area display is lost.

  In the present invention, the solenoids 36 are separately arranged on both sides of the frame 31 constituting the rear unit 30 constituting the variable prize-winning device 2, and the operation piece 41 is operated by the plunger of each solenoid. Is engaged with a rotating shaft 21 extending rearward from each blade member 20 to operate each blade member. In addition, solenoids are arranged at rear positions corresponding to the blade members 20, respectively. Therefore, the blade member and the solenoid do not interfere with the display screen more than necessary, and the display area of the display can be fully utilized. Moreover, the lead wire connected to the solenoid 36 also passes along the detour path (path further outside the outer peripheral edge of the display) that bypasses the display screen, along the peripheral edge of the frame 31 (wiring path that is difficult to see from the front). Therefore, it is possible to prevent the lead wire from being visually recognized from the front by the player.

Next, the adjustment jig denoted by reference numeral 60 in FIGS. 3, 6, and 8 is rotated so that the height position of the bifurcated branch portion (clamping piece) 41 a of each operating piece 41 protrudes from each blade member 20. It is means for aligning with the height position of the shaft 21 (engagement shaft 21c).
In a state where the rear unit 30 is not assembled to the front unit 11, each blade member 20 is opened by its own weight. For this reason, when assembling the rear unit 30 with respect to the front unit 11, in order to accurately insert the rotating shaft 21 of each blade member into the bifurcated branch portion 41 a of each operation piece 41, The rotation angle of the piece 41 (the height position of the bifurcated branch portion) needs to be aligned with the rotation shaft 21. However, in reality, the rotation angle of each operating piece varies depending on the strength of the spring that urges the plunger, and when the rear unit is assembled to the front unit, each rotation shaft fits into each bifurcated branch. A situation that does not match occurs.

Therefore, in the present invention, the adjustment jig 60 is inserted into the opening 31b provided in advance in the frame 31 and engaged with the base end portion of each operation piece 41, whereby the rotation angle of each operation piece is set to the rotation shaft 21. When the rear unit 30 is held in a state where it is matched with the height position of the rear end portion and the rotation angle of the operating piece is set in this way, when the rear unit 30 is assembled to the front unit 11, each bifurcated branch Each rotating shaft is fitted in the part.
That is, the adjustment jig 60 includes a tip member 61 having a fitting recess 61 a at the tip, and a grip portion 62 extending from the tip member 61. Openings 31b are formed in both side walls 31a of the frame 31 so as to allow the base end of the operating piece 41 to communicate with the outside, and recesses provided in the distal end member 61 by inserting the adjusting jig 60 into the respective openings 31b. The base end portion of the operating piece 41 can be sandwiched by 61a, and the height position of the distal end portion of the operating piece can be fixed.

In the example of FIG. 8, the bifurcated branch portion 41a of the operating piece 41 before assembling the adjustment jig is positioned upward as shown by the broken line, but at this height position, the rotation extends from the blade member in the open state. Since the shaft 21 (engagement shaft 21c) cannot be received, the adjustment piece 60 is used to lower the operating piece by the required angle as shown by the solid line so as to align with the rotating shaft 21. ing.
Therefore, by setting the rear unit 30 as it is at the set position provided on the back side of the front unit 11, the engagement between the rotating shaft 21 and the operating piece 41 is completed, and the number of assembling steps can be reduced. Can do.

  As described above, according to the present invention, a large-area display is arranged in the rear center portion of the variable winning device including two blade members driven by a solenoid, thereby increasing the lateral interval between the two blade members. It is possible to deal with a case where it is necessary to dispose them apart and it is difficult to drive the two blade members by one solenoid. In other words, in the present invention, since the solenoids are arranged in a one-to-one relationship at the rear positions corresponding to the blade members that are previously arranged at positions avoiding the display screen, the blade members and the solenoid interfere with the display screen. It is possible to operate the blade member at an arbitrary timing while eliminating the above. Furthermore, durability of each solenoid can be improved.

In the pachinko gaming machine of the present embodiment configured as described above, when the game ball B wins the left starting port (starting winning port) 3 or the electric tulip (ordinary electric accessory) 4 shown in FIG. The following game modes are adopted according to the lottery performed.
First, as a result of the lottery, when a big win is won, the special symbol display device 80 and the effect display device 85 (display 51) display the jackpot symbol to cause a special symbol variation jackpot that is the first special gaming state. . In this case, the variable winning device 2 performs an operation of opening the movable piece 20 (blade member), and the game ball B that has won a prize in the variable winning device 2 is detected by the winning ball detection switches 82L and 82R. Such a jackpot operation is one round of either a period during which a predetermined number (for example, 9) of game balls B wins in the variable winning device 2 or a period during which the movable piece 20 is opened / closed a predetermined number of times (for example, 18 times). Until the end of a predetermined round (for example, 15 rounds). Further, in the special game state due to the jackpot winning, the specific area detection switch 83 in the variable winning device may be disabled.

  Note that such a big hit operation is merely an example, and the movable piece 20 is continuously opened and closed until a predetermined number of game balls B are won in the variable winning device 2, or a game is played in the variable winning device 2. The movable piece 20 may be kept open until a predetermined number of balls B are won. Further, in the special game state associated with the jackpot, the specific area detection switch 83 in the specific area 84 may have a function as a continuation switch for continuing the special game state.

  Next, when winning a small winning as a result of the lottery, the small winning symbol is displayed on the special symbol display device 80 and the effect display device 85 (display 51), and the movable piece 20 of the variable winning device 2 is set a predetermined number of times (for example, (Open once or twice). At this time, when the game ball B that has won in the variable winning device 2 wins the specific area 84 and passes the specific area detection switch 83, a specific area passing jackpot that is the second special game state is generated. Also in this case, the variable winning device 2 performs the operation of opening the movable piece 20 and detects the game ball B that has won the prize in the variable winning device 2 by the winning ball detection switches 82L and 82R. Such a jackpot operation is a round of either a period during which a predetermined number (for example, 9) of game balls B wins in the variable winning device 2 or a period during which the movable piece 20 opens and closes a predetermined number (for example, 18 times). Until the end of a predetermined round (for example, 2 rounds, 8 rounds, 15 rounds). In this case as well, the special area detection switch 83 in the variable winning device 2 may be disabled in the special game state due to the big win.

Similarly to the above, the movable piece 20 is continuously opened and closed until a predetermined number of game balls B are won in the variable winning device 2, or the movable piece is moved until a predetermined number of game balls B are won in the variable winning device 2. 20 may be kept open. Further, in the special game state associated with the jackpot, the specific area detection switch 83 in the specific area 84 may have a function as a continuation switch for continuing the special game state.
If the result of the lottery is a loss, the special symbol display device 80 and the effect display device 85 display the shift symbol, and the opening operation of the movable piece 20 of the variable winning device 2 is not performed.

In step S4, it is determined whether or not the number of holds is “1” or more. If the number of holds is “1” or more, the process proceeds to step S5. Otherwise, the process returns to step S1.
In step S5, as a special symbol fluctuation lottery process, for example, one random number value is selected by lottery from random number values “0 to 100”, and in step S6, “1” is subtracted from the reserved number, and then in step S7. The random value obtained by the special symbol variation lottery process is acquired.

  Next, in step S8, it is determined whether or not the acquired random number value is “0”. If the random number value is “0”, it is determined that the specific symbol variation jackpot has been won, and the process proceeds to step S9. In step S9, the CPU 152 performs control to cause the CPU 172 of the symbol control unit 171 to select a variation pattern corresponding to the jackpot. In step S10, the jackpot flag value is set to “1”, and in step S11, the CPU 172 is caused to execute symbol variation processing. As a result, a symbol corresponding to the jackpot is displayed on the special symbol display device 80, and an effect display according to the selected jackpot variation pattern is performed on the effect display device 85.

  After that, if it is determined in step S12 that the special symbol display device 80 has stopped at the specific symbol, the process proceeds to step S13, and whether or not the jackpot is won in step S13, that is, whether or not the jackpot flag value is “1”. Is determined. In this case, since the jackpot flag value is “1”, the process proceeds to step S14. In step S14, the jackpot flag value is returned to “0”, and then in step S15, jackpot processing such as opening operation of the variable winning device 2 which is a jackpot is performed. After the big hit process is completed, the process returns to step S1 and continues.

  On the other hand, if it is determined in step S8 that the acquired random number value is not “0”, the process proceeds to step S16 to determine whether the random number value is “1” to “10”. Here, if the random number value is “1” to “10”, the process proceeds to step S17, and the CPU 52 controls the CPU 172 of the symbol control unit 171 to select a variation pattern corresponding to the deviation, and in step S11. The symbol variation process is executed. As a result, the special symbol display device 80 displays a symbol corresponding to the shift, and the effect display device 85 displays an effect according to the selected deviation variation pattern.

After that, if it is determined in step S12 that the special symbol display device 80 has stopped at the specific symbol, the process proceeds to step S13, and it is determined whether or not the jackpot is won in step S13. In this case, since the jackpot is not won, the process returns from step S13 to step S1.
If it is determined in step S16 that the acquired random number value is not “1” to “10”, that is, if the random number value is any one of “11” to “100”, the process proceeds to step S18, and the CPU 152 The CPU 172 of the symbol control unit 171 performs control to select a variation pattern corresponding to the small hit.

  Next, in step S19, the opening process of the movable piece solenoid 121a for driving the movable piece 20 of the variable winning device 2 is performed. In the subsequent step S20, the winning in the variable winning device 2 is detected by the big winning ball detection switches 82L and 82R. In this case, the process proceeds to step S21, where it is determined whether or not a game ball has won in the specific area 84 by the specific area detection switch 83. If it is determined that the game ball has won the specific area, the process proceeds to step S22, the jackpot flag value is set to “1”, the process proceeds to step S13, and whether or not the jackpot is won in step S13. To determine. In this case, since the flag value is “1”, the process proceeds to step S14. In step S14, the jackpot flag value is returned to “0”, and then in step S15, jackpot processing such as opening operation of the variable winning device 2 which is a jackpot is performed. After the big hit process is completed, the process returns to step S1 and continues. If the winning of the game ball in the variable winning device 2 cannot be detected in step S20, or if the winning of the game ball in the specific area 84 cannot be detected in step S21, the process returns to step S1 to perform the process. continue.

  As described above, the pachinko gaming machine according to the present embodiment has a first game characteristic that a big win is generated by a lottery performed when a game ball wins at a start winning opening such as the start opening 3 or the electric tulip 4, and a start winning prize. A big hit occurs when a game ball that has won a prize in the variable winning device 2 passes through the specific area detection switch 83 in the specific area 84 when a small win is generated by a lottery performed when a game ball wins in the mouth. It has a configuration having two game characteristics called second game characteristics.

In addition, the pachinko gaming machine of the present embodiment described so far is not limited to the above-described game characteristics, but can be applied to pachinko gaming machines having game characteristics conventionally referred to as two types.
FIG. 11 is a flowchart showing processing of a pachinko gaming machine having two types of game characteristics. Note that the processing described below is also realized mainly by the CPU 152 of the game control unit 151 executing a program stored in the ROM 153.

  In this case, the CPU 152 first determines whether or not the game ball has won the left start port 3 or the electric tulip 4 by the start winning switches 112a and 113a (S31), and if it is determined that the game ball has won, step Proceed to S32. In step S32, the opening process of the movable piece solenoid 121a for driving the movable piece 20 of the variable winning device 2 is performed. In subsequent step S33, when a winning in the variable winning device 2 is detected by the big winning ball detection switch 82, the process proceeds to step S34. In step S34, the game ball won in the specific region 84 by the specific region detecting switch 83 is stored in the variable winning device 2. It is determined whether or not the specific area has been passed. Here, when it is determined that the game ball has passed the specific area, the process proceeds to step S35 and a jackpot process is performed such that the opening operation of the variable winning device 2 is performed. After the big hit process is completed, the process returns to step S31 and the process is continued. If no winning in the variable winning device 2 is detected in step S33, or if no winning in the specific area 84 is detected in step S34, the process returns to step S31 to continue the process.
