Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gaming machine such as a pachinko gaming machine.
[0002]
[Prior art]
Conventionally, in a game board of a pachinko machine, a center frame provided with a display device is disposed almost at the center of the game board. In recent years, a rolling part (generally referred to as a stage) is formed below the center frame so that the player can enjoy the behavior of the game ball so that the game ball rolls in the left-right direction. is there.
[0003]
However, the behavior of the game ball in the rolling part has a certain pattern of repeatedly rolling in the left-right direction on the same plane, so there is a risk of reducing interest. For this reason, there has been proposed a structure in which a plurality of rolling surfaces are provided in the rolling part, and these rolling surfaces are arranged stepwise so as to become lower in order toward the surface side of the game board.
[0004]
[Problems to be solved by the invention]
However, as described above, even if a plurality of rolling surfaces are formed in a step shape, the game ball can only flow down in one direction. I was able to predict. That is, it was easy to get bored and lacked interest.
[0005]
Therefore, an object of the present invention is to provide a gaming machine that can give a player a visual interest by changing the behavior of a game ball in a complex manner.
[0006]
[Means for Solving the Problems]
Means 1 for solving the problem is a gaming machine including a rolling part for rolling a game ball in the left-right direction, and the rolling part includes at least two front sides arranged in parallel in the front-rear direction. In the vicinity of the center of the rolling portion in the rolling direction, the rear rolling surface is higher than the front rolling surface, and the vicinity of the end of the rolling portion. Then, the front rolling surface and the rear rolling surface are substantially the same height, or the front rolling surface is higher than the rear rolling surface.
[0007]
According to the means 1, when a game ball is thrown into the rear rolling surface, the game ball tries to roll left and right on the rear rolling surface, but in the vicinity of the center in the rolling direction, Since the rear rolling surface is higher than the front rolling surface, the game ball passing near the center may jump out from the center and move to the front rolling surface. In this case, the game ball rolls on the front rolling surface and reaches the vicinity of the end of the front rolling surface. On the other hand, in the vicinity of the end, the front rolling surface is substantially the same height as the rear rolling surface or higher than the rear rolling surface, so the game ball that has reached the end of the front rolling surface is There is a possibility of moving from the front rolling surface to the rear rolling surface. That is, the game ball can be reciprocated between the front rolling surface and the rear rolling surface.
[0008]
In addition to the configuration of the means 1, the means 2 has a shape in which the front rolling surface and the rear rolling surface are curved in a substantially arc shape in the vertical direction, and the vicinity of the center of the front rolling surface A discharge portion for allowing the game ball to flow down is formed.
[0009]
According to the means 2, the game ball rolls in the left-right direction while drawing an arc according to the rear rolling surface curved in a substantially arc shape. Further, when moving from near the center to the front rolling surface, it follows the front rolling surface to reach the vicinity of the end while drawing an arc, and then moves to the front rolling surface. On the other hand, when the speed of the game ball is low or the like does not reach the vicinity of the end portion on the front rolling surface, it is discharged from a discharge portion formed near the center of the front rolling surface. Thus, depending on the momentum of the game ball and the like, the flow direction of the game ball can be divided into two cases: when returning to the front rolling surface and when discharging from the discharge portion.
[0010]
Means 3 is characterized in that, in addition to the constitution of means 1 or means 2, the vicinity of the center of the rear rolling surface is an inclined surface inclined downward toward the front rolling surface. .
[0011]
According to the means 3, since the vicinity of the center of the rear rolling surface is inclined downward toward the front, the game ball passing near the center of the rear rolling surface has a rolling direction according to the inclined surface. It changes toward the front. That is, the game ball on the rear rolling surface can be guided to move to the front rolling surface.
[0012]
Means 4 is that, in addition to the structure of any one of means 1 to means 3, the vicinity of the end of the front rolling surface is an inclined surface inclined downward toward the rear inclined surface. Features.
[0013]
According to the means 4, since the vicinity of the end of the front rolling surface is inclined downward toward the rear, the game ball reaching the vicinity of the end of the front rolling surface has a rolling direction according to the inclined surface. It changes backward. Accordingly, the game ball on the front rolling surface can be guided to move to the rear rolling surface.
[0014]
The means 5 is characterized in that, in addition to the structure of any one of the means 1 to 4, the vicinity of the center of the front rolling surface is an inclined surface that is inclined upward toward the front.
[0015]
For example, when a game ball moves from near the center of the rear rolling surface to the front rolling surface, if the momentum to move forward is too strong, it will deviate from the rolling surface as it is and the front of the front rolling surface There is a risk of being discharged from the edge.
[0016]
However, according to the means 5, since the vicinity of the center of the front rolling surface is inclined upward toward the front, the game ball that has moved to the front rolling surface is prevented from rolling forward by the inclined surface. Is done. Therefore, it is possible to suppress the game ball from deviating from the front rolling surface.
[0017]
The means 6 is characterized in that, in addition to the structure of the means 5, the width of the front rolling surface in the vicinity of the center is narrower than the radius of the game ball.
[0018]
According to the means 6, since the width of the passage in the vicinity of the center of the front rolling surface (discharge portion) is narrower than the radius of the game ball, the center of gravity of the game ball passes through the center of the front rolling surface. It will be located outside. Therefore, when the speed of the game ball is low, the game ball can be reliably discharged from the vicinity of the center. When the speed of the game ball is high (when the momentum is strong), it is possible to pass the vicinity of the center along the front rolling surface. That is, it can be rolled in the left-right direction on the front rolling surface without being returned to the rear rolling surface.
[0019]
The means 7 is characterized in that, in addition to the structure of any one of the means 1 to the means 6, the width of the front rolling surface becomes wider from the vicinity of the center toward the end.
[0020]
For example, when a game ball moves from near the center of the rear rolling surface to the front rolling surface, a forward motion is added to a lateral motion, so that the gaming ball is in the combined direction of those motions. It will roll forward diagonally. That is, when rolling on the front rolling surface, the game ball moves away from the rear rolling surface as it moves from the center to the end.
[0021]
According to the means 7, the width of the front rolling surface becomes wider from the center to the end. For this reason, the deviation from the front rolling surface can be effectively suppressed until the game ball reaches the vicinity of the end.
[0022]
By the way, when the structure of the means 1 is described operatively, it becomes as follows.
That is, the means 8 is a gaming machine provided with a rolling part for rolling the game ball in the left-right direction, and the rolling part has at least two front rolling surfaces and a rear rolling surface in the front-rear direction. In the vicinity of the center of the rolling portion in the rolling direction, the game ball rolls from the rear rolling surface to the front rolling surface, and near the end of the rolling portion, The front rolling surface and the rear rolling surface are formed so that the game ball rolls from the front rolling surface to the rear rolling surface.
[0023]
Further, the method for rolling the game ball is not necessarily limited to the actual rolling part, and is also effective as a rolling method for the game ball.
That is, the means 9 has at least two front rolling surfaces and a rear rolling surface arranged in the front-rear direction in the rolling portion, and the rear rolling surface is located near the center of the rolling portion in the rolling direction. The game ball is rolled from the front rolling surface to the front rolling surface, and the gaming ball is rolled from the front rolling surface to the rear rolling surface in the vicinity of the end of the rolling portion.
[0024]
According to the means 8 or 9, it is possible to reciprocate the game ball between the front rolling surface and the rear rolling surface as in the case 1.
[0025]

[0027]
In addition, the pachinko gaming machine 2 incorporates a speaker 21 (see FIG. 10) and a plurality of lamps 22 as decorative light emitting elements for the purpose of enhancing the gaming effect. The speaker 21 emits a sound effect or changes the type of the sound effect in accordance with the progress of the game. Examples of the lamp 22 include known lamps such as a windmill lamp, a decoration lamp, a sleeve lamp, and a side lamp, and these change the mode of light emission according to the progress of the game.
[0028]
The display device 12 includes a liquid crystal display (LCD). Note that a CRT, a dot matrix, a light emitting diode (LED), electroluminescence (EL), a fluorescent display tube, or the like may be used instead of the LCD. On the screen of the display device 12, for example, three symbol rows (left symbol row, middle symbol row, right symbol row) arranged in the left-right direction are displayed. Each symbol row is composed of a plurality of types of symbols, including numbers, characters, combinations thereof, and the like.
[0029]
In the display device 12, the variation of the symbols in each symbol row is started all at once based on the winning of the game ball 7 to the start port 9. The symbol variation is stopped in a predetermined stop order, for example, left symbol sequence, right symbol sequence, middle symbol sequence. Then, when the variation of all the symbol sequences stops, the combination of the displayed symbols (stop symbols) is a predetermined jackpot combination, that is, a combination in which the same type of stop symbols are arranged along the jackpot line ( For example, “7”, “7”, “7”) may be obtained. When the winning combination is established, the winning area of the big winning opening 10 is released, and the player can acquire a lot of winning balls.
[0030]
As shown in FIGS. 2 to 4, the main body frame 13 (generally referred to as a center frame) includes a ceiling portion 23, a side portion 24, and a lower portion 25, and a window portion 13 a is formed at the center. An attachment member (not shown) for attaching the display device 12 to the window portion 13a is provided at the rear portion of the main body frame 13. A ceiling ornament 26 including a holding lamp 26a and a windmill 26b is provided on the ceiling 23, and an entrance 27 for allowing the game ball 7 to enter the special game area 14 is formed on the upper surface thereof. Further, shoulder decorations 28 are provided on the left and right sides of the ceiling decoration 26. The game ball 7 entered from the entrance 27 is guided obliquely downward in the left-right direction according to a passage 29 formed inside the ceiling ornament 26 and the shoulder ornament 28.
[0031]
A rolling portion 30 is formed on the upper surface of the lower portion 25 of the main body frame 13, and the behavior of the game ball 7, that is, the rolling in the left-right direction can be visually recognized in the rolling portion 30. . Furthermore, the left and right side portions 24 are provided with an inductor 31 for communicating the passage 29 and the rolling portion 30.
[0032]
Specific configurations of the rolling unit 30 and the inductor 31 will be described with reference to FIGS. Here, FIG. 5 is a perspective view showing the configuration of the rolling unit 30 and the inductor 31, FIG. 6 is a plan view showing the configuration of the rolling unit 30, and FIG. 7 is also a front view. 8 is a cross-sectional view of the rolling section 30 shown in FIG. 6, wherein (a) shows an AA cross section, (b) shows a BB cross section, and (c) shows a CC cross section.
[0033]
The rolling part 30 is a horizontally long member that is curved in a substantially arc shape in the vertical direction and is formed in a step shape toward the front. The rolling portion 30 includes a rear rolling surface 35 and a front rolling surface 36 that are juxtaposed in the front-rear direction. As shown in FIG. 6, the rear rolling surface 35 has a planar shape in which the rear edge is linear and the front edge is arcuate, and the width L1 of the central portion in the rolling direction (left and right direction on the paper surface) is Narrowest and wider toward the end. The width L1 of the central portion is narrower than the diameter D of the game ball 7.
[0034]
Further, as shown in FIGS. 8A and 8B, the rear rolling surface 35 is an inclined surface inclined downward toward the rear, and a guide wall is provided at the rear edge of the rear rolling surface 35. 39 is erected. However, as shown in FIG. 8 (c), the central portion of the rear rolling surface 35 is a slope slightly inclined downward toward the front, and the game ball 7 is discharged forward from this slope. Is possible. That is, the rear discharge part 40 for discharging the game ball 7 is constituted by this slope. The rearward inclination of the rear rolling surface 35 continuously changes so that the end side is the largest and gradually decreases toward the central portion. Specifically, the inclination of the rear rolling surface 35 is 7.7 ° in the AA cross section shown in FIG. 8A and FIG. BB section shown in FIG. 8) is 6.4 °, and CC section shown in FIG. 8C is −4.0 °. Further, a resin sealing member 38 having a small friction coefficient is attached to the surface of the guide wall 39 (see FIG. 6), and the loss of kinetic energy of the game ball 7 is suppressed.
[0035]
The front rolling surface 36 has a shape in which both the rear edge and the front edge are curved in an arc shape toward the rear, but the front edge has a smaller radius of curvature than the rear edge. That is, the front-side rolling surface 36 has the narrowest width L2 at the center portion and becomes wider toward the end portion. Note that the width L2 of the central portion is narrower than the radius of the game ball 7. Further, as shown in FIGS. 8A, 8B, and 8C, the front rolling surface 36 is an inclined surface that is inclined downward toward the rear. In particular, the degree of inclination is the central portion (( C) is the largest, and continuously changes so as to decrease toward the end side. Specifically, the inclination of the front rolling surface 36 is 4.6 ° in the AA cross section shown in FIG. 8 (a) and in the BB cross section when the backward downward inclination with respect to the horizon is taken as plus. It is 5.6 ° and 16 ° in the CC cross section. Although the central portion of the front rolling surface 36 is inclined downward toward the rear, the width L2 thereof is narrower than the radius of the game ball 7, so that the game ball 7 that passes through the central portion of the front rolling surface 36 is used. Can be discharged from the leading edge. That is, the front side discharge part 41 for discharging the game ball 7 is comprised by this center part. Here, the front discharge portion 41 corresponds to the discharge portion of the present invention.
[0036]
Further, comparing the rear rolling surface 35 and the front rolling surface 36, the rear rolling surface 35 is higher in the vicinity of the center O (see FIG. 8C), but in the vicinity of the end H (FIG. 8). On the contrary, the front rolling surface 36 is higher in (a) and (b). That is, the radius of curvature of the two rolling surfaces 35, 36 that are curved in the vertical direction is larger on the rear rolling surface 35 than on the front rolling surface 36. In other words, the inclination of the rear rolling surface 35 is gentler than that of the front rolling surface 36.
[0037]
A braking chamber 43 and two guiding portions 44 are formed in front of the front rolling surface 36. The braking chamber 43 is a space large enough to accommodate one game ball 7. The upper surface and the front surface are opened, and the bottom surface 43 a is inclined downward toward the front. The guiding portion 44 is a member for guiding the game ball 7 discharged from the front rolling surface 36 to the upper surface (open portion) of the braking chamber 43, and an inclined surface 45 inclined toward the braking chamber 43, The front wall portion 46 is erected from the front edge of the inclined surface 45. Further, a second rolling portion 47 that is curved in an arc shape in the vertical direction is formed in front of the braking chamber 43 and the guide portion 44. A discharge portion 47a is formed at the center of the second rolling portion 47 in the rolling direction, and the discharge portion 47a and the bottom surface 43a of the brake chamber 43 are continuous surfaces.
[0038]
On the other hand, the inducer 31 is for guiding the game ball 7 entered from the entrance 27 to the rolling unit 30. As shown in FIG. 5, the inductor 31 includes a ladder member 50 and a wall member 51 that are arranged to face each other. The ladder member 50 includes a pair of support columns 52 erected in the vertical direction, and a plurality of horizontal rails 53 or the like installed between them. A guide piece 55 extends from the lower end of the ladder member 50 and regulates the direction of the game ball 7 discharged from the outlet 32. The opening surrounded by the pair of support columns 52 and the horizontal rails 53 is sized so that the game ball 7 does not pass through.
[0039]
On the surface of the wall member 51 in the inductor 31, a recess 59 that is recessed in a substantially arc shape toward the back side is continuously formed from the upper end to the lower end. In addition, in the recess 59, substantially triangular protrusions 60 protruding forward are formed at predetermined intervals in the vertical direction. The interval between the protrusions 60 is equal to the interval between the horizontal bars 53 in the ladder member 50.
[0040]
The ladder member 50 and the wall material 51 are arranged at a narrower interval than the diameter D of the game ball 7 so that the horizontal rails 53 in the ladder member 50 and the protrusions 60 in the wall material 51 are alternated. For this reason, the game balls 7 passing through the inductor 31 fall while alternately colliding with the cross rails 53 and the protrusions 60 formed alternately. That is, the game ball 7 falls while being decelerated, and is guided in a decelerated state to the end of the rear rolling surface 35 in the rolling unit 30. Note that the outlet 32 of the inductor 31 is located on the extension of the guide wall 39. Further, the floor surface of the outlet 32 is higher than the end portion of the rear rolling surface 35. That is, a step 42 is formed between the outlet 32 and the rear rolling surface 35.
[0041]
By the way, as shown in FIG. 10, a main control board 63 is incorporated in the pachinko gaming machine 2, and various switches, a holding lamp 26 a, a solenoid 19, and the like are connected to the main control board 63. Further, the display device 12 is connected to the main control board 63 via the display control board 66, and the speaker 21 is connected via the audio control board 64. Further, the lamp 22 is connected to the main control board 63 via the lamp control board 65, and the payout motor 15 is connected via the payout control board 67.
[0042]
Each of the control boards 63 to 67 includes a read-only memory (ROM) that stores a predetermined control program and initial data in advance, a central processing unit (CPU) that executes various arithmetic processes according to the control program stored in the ROM, and a CPU. A random access memory (RAM) or the like for temporarily storing the calculation result is provided.
[0043]
Next, the movement of the game ball 7 in the rolling unit 30 will be described with reference to FIGS. The game ball 7 entering from the entrance 27 is guided to the end of the rear rolling surface 35 of the rolling unit 30 through the guide path by the guide 31. Here, since the outlet 32 of the inductor 31 is disposed on the extension of the guide wall 39, the game ball 7 discharged from the outlet 32 is guided along the guide wall 39. Thereby, it is prevented that the game ball 7 collides with the guide wall 39 vigorously, and the change in the rolling direction due to the rebound on the guide wall 39 is suppressed.
[0044]
The game ball 7 guided to the rear rolling surface 35 repeatedly rolls in the left-right direction while drawing an arc according to the shape of the rear rolling surface 35. That is, the game ball 7 performs a rocking motion based on the law of energy conservation. At this time, since the rear rolling surface 35 is inclined downward toward the rear, a force is applied to the game ball 7 to roll backward along the inclined surface, and as a result, the game ball 7 rolls along the guide wall 39. To move. Thereby, the deviation of the game ball 7 from the front edge of the rear rolling surface 35 is suppressed.
[0045]
On the rear rolling surface 35, the game ball 7 rolls along the guide wall 39. However, the rear discharge portion 40 of the central portion has a slight downward slope toward the front, so that the speed of the game ball 7 is increased. When is reduced, the rolling direction changes toward the front. Moreover, since the width L1 of the rear discharge portion 40 is narrower than the diameter D of the game ball 7, the game ball 7 is easily discharged as the speed decreases.
[0046]
Here, since the rear discharge portion 40 is higher than the front discharge portion 41 of the front rolling surface 36, the game ball 7 discharged from the rear discharge portion 40 moves to the front discharge portion 41. At this time, if the momentum of the game ball 7 is strong, the game ball 7 rolls in the left-right direction while drawing an arc according to the shape of the front rolling surface 36, and reaches the vicinity of the end of the front rolling surface 36. Since the front discharge portion 41 of the front rolling surface 36 is inclined upward toward the front, the game ball 7 that has moved to the front rolling surface 36 is prevented from rolling forward. For this reason, even if the game ball 7 has a strong forward momentum, it can be prevented from being discharged from the front edge of the front rolling surface 36 as it is. By the way, the game ball 7 that has moved to the front rolling surface 36 is subjected to forward motion with respect to motion in the left-right direction, and therefore the game ball 7 rolls diagonally forward, which is the combined direction of those motions. It will be. That is, when rolling on the front rolling surface 36, the game ball 7 moves away from the rear rolling surface 35 as it moves from the front discharge portion 41 toward the end portion. However, in this embodiment, since the width of the front rolling surface 36 is increased toward the end portion, the deviation of the gaming ball 7 from the front rolling surface 36 until the game ball 7 reaches the end portion. Is effectively suppressed.
[0047]
On the other hand, in the vicinity of the end H, the front rolling surface 36 is higher than the rear rolling surface 35 and the front rolling surface 36 is inclined downward toward the rear, so that the end portion of the front rolling surface 36 is The game ball 7 that has reached the vicinity H moves from the front rolling surface 36 to the rear rolling surface 35. That is, the game ball 7 reciprocates between the two rolling surfaces 35 and 36. If the game ball 7 does not reach the end vicinity H, such as when the momentum of the game ball 7 is weak, the game ball 7 is discharged from the front discharge unit 41. In particular, since the width of the front discharge portion 41 is narrower than the radius of the game ball 7, when the game ball 7 passes through the front discharge portion 41, its center of gravity is positioned forward of the front edge of the front discharge portion 41. Become. Therefore, when the speed of the game ball 7 is low, the game ball 7 is reliably discharged from the front discharge portion 41. When the speed of the game ball 7 is high, the game ball 7 may pass through the front discharge portion 41. In this case, the game ball 7 repeatedly rolls on the front rolling surface 36 in the left-right direction.
[0048]
The game ball 7 discharged from the front discharge portion 41 of the front rolling surface 36 is guided to the inclined surface 45 of the guide portion 44 and is put into the braking chamber 43. Here, since the front wall portion 46 is erected on the front edge of the guide portion 44, braking is performed without deviating from the guide portion 44 even when the game ball 7 discharged from the front discharge portion 41 is strong. Guided to the upper surface of the chamber 43. Further, since the side wall 43b on the upper side of the braking chamber 43 is expanded upward, for example, even when the two game balls 7 are guided substantially simultaneously by the guiding portions 44 arranged on the left and right sides of the braking chamber 43. , The risk of collision with each other is reduced and they are thrown in smoothly. When the position of the game ball 7 discharged from the front discharge portion 41 matches the position of the brake chamber 43, the game ball 7 is directly inserted into the brake chamber 43 without passing through the guide portion 44.
[0049]
The game ball 7 thrown in from the upper surface of the brake chamber 43 is restrained from rolling by the brake chamber 43. In other words, since the lateral width of the brake chamber 43 is substantially equal to the diameter of the game ball 7, the game ball 7 is stopped for a moment without rolling in the left-right direction inside the brake chamber 43. Thereafter, the game ball 7 is released forward according to the inclination of the bottom surface 43 a of the braking chamber 43. By the way, a second rolling part 47 is formed in front of the braking chamber 43 and the guide part 44, and a surface where the discharge part 47a of the second rolling part 47 and the bottom surface 43a of the braking chamber 43 are continuous with each other. Therefore, the game ball 7 released from the braking chamber 43 flows down in the direction of the starting port 9 (see FIG. 1) across the discharge part 47a of the second rolling part 47. Thus, since the release direction of the game ball 7 is restricted by the braking chamber 43, almost all of the game ball 7 that has rolled in the rolling unit 30 wins the start opening 9.
[0050]
As described above, in the pachinko gaming machine 2 described above, the game ball 7 can be reciprocated between the front rolling surface 36 and the rear rolling surface 35, so that the rolling of the game ball 7 is complicated. Can be changed. That is, in addition to rolling in the left-right direction, rolling in the front-rear direction and the up-down direction is added, and the behavior of the game ball can be fully enjoyed. In addition, since it can be realized with a very simple structure without using magnets or power, it is possible to suppress an increase in manufacturing cost and reduce the burden on the manufacturer.
[0051]
In the pachinko gaming machine 2 described above, the vicinity O of the center of the rear rolling surface 35 is inclined downward toward the front, so that the game ball 7 on the rear rolling surface 35 is moved to the front rolling surface 36. On the other hand, since the vicinity H of the end portion of the front rolling surface 36 is inclined downward toward the rear rolling surface 35, the game ball 7 reaching the end portion H of the front rolling surface 36 is reached. Can be guided to the rear rolling surface 35. Therefore, it can be smoothly reciprocated.
[0052]
Further, in the pachinko gaming machine 2 described above, the vicinity O of the center of the front rolling surface 36 is inclined upward and the width of the front rolling surface 36 is increased from the center O toward the end H. Since it becomes wide, it can suppress that the game ball 7 which moved to the front side rolling surface 36 deviates from the front edge of the front side rolling surface 36.
[0053]
The present invention has been described with reference to preferred embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention as described below. And design changes are possible.
[0054]
That is, in the pachinko gaming machine 2 of the above-described embodiment, the front rolling surface 36 is higher than the rear rolling surface 35 in the vicinity of the end H of the rolling unit 30, but FIG.
