Japanese Patent Laid-Open No. 15-126396

  It is an object of the present invention to provide a ball game machine that can improve an accessory and give a player a great interest.

  In order to achieve the above object, the invention according to claim 1 is a ball game machine having an accessory, wherein the accessory extends substantially parallel to the width direction of the ball game machine, and is at least approximately A spiral rolling guide portion having a smooth inner peripheral surface, at least a portion of the front side thereof having a transparent cylindrical shape, and guiding that the game ball rolls spirally on the inner peripheral surface. This is a ball game machine.

The phrase “having at least a substantially smooth inner peripheral surface” includes a case of “having a substantially smooth inner peripheral surface” and a case of “having a smooth inner peripheral surface”.
Examples of the case of “having a smooth inner peripheral surface” include the case of “having an inner peripheral surface of a circular cross section” and the case of “having an inner peripheral surface of an elliptical cross section”.
As a case of “having a substantially smooth inner peripheral surface”, there is a case of “having an inner peripheral surface having an octagonal cross section”.
In addition to “cylindrical shape”, “cylindrical shape” includes “elliptical cylindrical shape”, “octagonal cylindrical shape”, and the like. Further, there is a case of “having an outer peripheral surface having a square cross section and an inner peripheral surface having a circular cross section”.
Further, the “cylindrical shape” is not limited to a uniform inner peripheral diameter, and may gradually change along the length direction thereof.

  “Game balls roll in a spiral” includes “game balls roll in a spiral based on gravity”, and moreover, “game balls roll in a spiral based on gravity alone”. There is "it moves".

  In the ball game machine of the present invention, the game ball rolls spirally on the inner peripheral surface of the spiral rolling guide portion, which is visually recognized by the player. For this reason, in this ball game machine, a great interest can be given to the player.

  The following two inventions (first and second related inventions) can be considered as inventions related to this invention. An invention having the characteristics of the two inventions is also conceivable.

First related invention "A ball game machine of the invention according to claim 1,
For the spiral rolling guide portion, an inflow portion is provided for allowing a game ball to flow in along a direction having a component in a direction from the upstream side to the downstream side of the spiral rolling guide portion.
A ball game machine. "

  In the ball game machine of the present invention, the game ball flows into the spiral rolling guide portion along a direction having a component in the direction from the upstream side to the downstream side of the spiral rolling guide portion. In this way, the game ball is given a velocity component from the upstream side to the downstream side in the spiral rolling guide portion, and the game ball rolls smoothly in a spiral manner in the spiral rolling guide portion. .

Second related invention "A ball game machine of the invention according to claim 1,
As it goes from the upstream side to the downstream side of the spiral rolling guide portion, the axis of the spiral rolling guide portion is inclined from the horizontal so that it gradually goes downward,
A ball game machine. "

  In the ball game machine of the present invention, the game ball that rolls inside the spiral rolling guide portion whose axis is inclined from the horizontal is based on the inclination from the upstream side of the spiral rolling guide portion. Trying to go downstream. In this way, the game ball is given a velocity component from the upstream side to the downstream side in the spiral rolling guide portion, and the game ball rolls smoothly in a spiral manner in the spiral rolling guide portion. .

  The invention according to claim 2 is the ball game machine of the invention according to claim 1, wherein a ball receiving portion provided at a position higher than the bottom portion is provided in the spiral rolling guide portion. Thus, the game ball that has reached the ball receiving portion and the game ball that has not reached the ball receiving portion flow out of the accessory through different paths.

In addition to the action and effect of the bullet ball game machine according to the first aspect of the present invention, the following action and effect can be obtained.
That is, when the game ball that has spirally rolled on the inner peripheral surface of the spiral rolling guide portion reaches or does not reach the ball receiving portion, the game ball passes through the path through different paths. leak.
For this reason, the rolling pattern of the game ball after rolling the spiral rolling guide portion is also of interest to the player, and the player can be given further interest.
In particular, in the present invention, when the possibility that the game ball flows out of the accessory through different paths and the winning prize is different, it is possible to give a greater interest to the player.

  The invention according to claim 3 is the ball game machine of the invention according to claim 2, wherein the accessory is formed with an outflow portion from which a game ball flows out of the accessory, and the ball receiving portion The game ball that has reached the ball and the game ball that has not reached the ball receiving portion flows out of the accessory in different directions through the outflow portion.

In the ball game machine of the present invention, in addition to the operation and effect of the ball game machine of the invention according to claim 2, the following operation and effect can be obtained.
In other words, when the game ball that spirally rolls on the inner peripheral surface of the spiral rolling guide portion reaches or does not reach the ball receiving portion, the game ball passes through different paths in the role. After flowing, it flows out of the accessory in different directions through the same outflow part.
For this reason, compared to the case where the game ball flows through different paths and then flows out from the accessory through different outflow portions, the whereabouts after the game ball has flowed out are of greater interest to the player. Can provide even greater interest to the person.
Also in the present invention, if the possibility that a game ball flows out of an accessory in a different direction through the same outflow portion and wins a winning opening is different, a greater interest is given to the player. Can be given.

The upstream end portion of the depth direction rolling portion 52 corresponds to the above-described inflow hole portion formed in the front side member 30 (frame-shaped front plate portion 32). The back direction rolling part 52 forms a path along which a pachinko ball rolls in the back direction together with a part of the front side member 30. The bottom (reference numeral omitted) of the path (backward rolling part 52) is inclined from the horizontal so as to gradually go downward from the near side to the far side.

As shown in FIG. 3, each of the pair of left and right spiral rolling guide members 60 a and 60 b has a main body portion 62 and a belt-like vertical plate portion 66.
The main body 62 (or the entire spiral rolling guide members 60a and 60b) of the spiral rolling guide members 60a and 60b is formed of a transparent or translucent synthetic resin.
The main body 62 of the spiral rolling guide members 60a and 60b has a cylindrical shape in which one (the center side in the width direction of the pachinko machine) is closed by the closing portion 64, and the other opening (reference number omitted). ) Is closed by lid members 68a and 68b.

As shown in FIGS. 2-7, the main-body part 62 of each helical rolling guide member 60a, 60b is carrying out the cylindrical shape extended substantially along the width direction of this pachinko machine.
That is, both the outer peripheral surface and the inner peripheral surface of the main body 62 have a circular cross section. Both the outer diameter and inner diameter of the main body 62 are uniformly formed along the length direction of the main body 62.
More precisely, the main body 62 of the left spiral rolling guide member 60a gradually moves downward from the left side (upstream side) to the center side (downstream side) in the width direction of the pachinko machine. It is slightly inclined from the horizontal. The same applies to the right spiral rolling guide member 60b.

As shown in FIG. 3, the belt-like vertical plate portion 66 is on the back side of the left side or the right side of the main body 62 in the width direction of the pachinko machine (left side in the case of the left spiral rolling guide member 60 a). Is formed.
Each strip-shaped vertical plate portion 66 corresponds to the flow lower portion 54 of each guide path forming member 50a, 50b. The flow part 54 of each guide path forming member 50a, 50b forms a path along which each pachinko ball falls together with each belt-like vertical plate part 66.

As shown in FIG. 3 and FIG. 4, the substantially lower half of the flow sections 54 (paths formed thereby) of the respective guide path forming members 50 a and 50 b is in the width direction of the pachinko machine as it goes downward. It is bent from the left side or the right side toward the center side (in the case of the left guide path forming member 50a, from the left side to the right side). That is, the guide path forming members 50a and 50b (substantially lower half portions) are bent from the upstream side to the downstream side of the spiral rolling guide members 60a and 60b.
Each guide path forming member 50a, 50b (its substantially lower half) corresponds to an inflow portion of the present invention (more precisely, related invention).
As shown in FIG. 3, inflow hole portions 63 are formed in the main body portions 62 of the spiral rolling guide members 60 a and 60 b so as to correspond to the flow lower portions 54 of the guide path forming members 50 a and 50 b. .

As shown in FIG. 2A, FIG. 3, FIG. 5A, etc., the first outflow is in the substantially central portion of the closed portion 64 of the main body portion 62 of each spiral rolling guide member 60a, 60b. A hole 71 is formed.
A second outflow hole 72 is formed in the lower part of the closing part 64 of the main body part 62. The lower edge portion of the second outflow hole portion 72 coincides with the bottom portion of the main body portion 62, and the pachinko ball located at the bottom portion of the main body portion 62 can flow out of the second outflow hole portion 72.

As shown in FIG. 2A and the like, the outflow rolling portion 48 is provided between the pair of left and right spiral rolling guide members 60a and 60b so as to connect the respective second outflow hole portions 72. Is provided.
The outflow rolling part 48 is curved so as to gradually go downward from the left and right end parts toward the center side, and is formed so as to gradually go downwards from the back side toward the near side. Yes.

As shown in FIGS. 3 to 7, a ball receiving member 80 is provided across a pair of left and right spiral rolling guide members 60 a and 60 b.
The ball receiving member 80 extends substantially along the width direction of the pachinko machine (exactly, it is slightly shifted from that, as will be described later).
As shown in FIGS. 6A and 7A, the left and right ends of the ball receiving member 80 are fixed to the cover members 68a and 68b of the spiral rolling guide members 60a and 60b. ing.
As shown in FIGS. 2A and 5A and the like, the ball receiving member 80 passes through the closed portions 64 of the spiral rolling guide members 60a and 60b through the first outflow hole portions 71, respectively. ing.

As shown in FIG. 3 and FIG. 5 to FIG. 7, most portions of the ball receiving member 80 and the portions located inside the spiral rolling guide members 60 a and 60 b (each main body portion 62) These are hook-shaped portions 82a and 82b. The hook-shaped portions 82a and 82b have an arcuate cross section that opens upward and protrudes downward.
Each hook-shaped portion 82a, 82b extends along the longitudinal direction of the main body portion 62 of each helical rolling guide member 60a, 60b substantially on the central axis of the main body portion 62 of each helical rolling guide member 60a, 60b. It extends. That is, it inclines so that it may go downward gradually as it goes to the center side from each edge part on either side.
The ball receiving member 80 (each of the bowl-shaped portions 82a and 82b) corresponds to the ball receiving portion of the present invention.

  As shown in FIG. 2, FIG. 3, FIG. 6 (a), and FIG. 7 (a), it is located in the central portion of the ball receiving member 80 and in the space between the spiral rolling guide members 60a and 60b. The part to do is the depth direction rolling part 84. The depth direction rolling portion 84 is formed so as to gradually go downward as it goes from the near side to the far side.

As shown in FIG. 2, a back side dropping portion 45 (FIG. 2B) is formed on the back side of the back direction rolling portion 84 (FIG. 2A). The rear-side falling part 45 has a rectangular tube shape with the upper and lower parts closed, and the front side part is open.
As shown in FIGS. 6 (a) and 7 (a), the opening portion (reference numeral omitted) is partitioned up and down by a depth direction rolling portion 84, and the upper portion thereof is an inflow opening portion 46. There is an outflow opening 47 at the lower part.
The bottom part (reference numeral omitted) of the back side dropping part 45 is inclined from the horizontal so as to gradually go downward as it goes from the back side to the near side, and continues to the rolling part 48 for outflow.

As shown in FIG. 2 (a), FIG. 3 and the like, a substantially horizontal band plate-like portion 36 extending in the width direction of the pachinko machine is formed in the lower part of the front side member 30, and at the center thereof. An outflow portion 37 is formed.
The outflow rolling part 48 described above is connected to the outflow part 37.
The outflow portion 37 has a concave shape along the width direction of the pachinko machine (that is, it is curved so as to gradually go downward from the left and right ends toward the center), and As it goes from the side toward the near side, it inclines from the horizontal so that it gradually goes downward. For this reason, the pachinko ball that has reached the outflow portion 37 in any of the paths also rolls in the central portion (the central portion in the width direction of the pachinko machine) of the outflow portion 37 or in the vicinity thereof, and the center accessory 20 Spill from.

As shown in FIGS. 6A and 7A, the start winning port 17 (described above based on FIG. 1) is provided directly below the outflow portion 37.
For this reason, in the outflow part 37, the pachinko ball that rolls the center part (the center part in the width direction of the pachinko machine) to the near side along the depth direction of the pachinko machine falls vertically downward from the outflow part 37. Therefore, there is a high possibility of winning at the start winning opening 17.
On the other hand, in the outflow part 37, the pachinko ball rolling in an oblique direction shifted from the depth direction of the pachinko machine falls obliquely downward from the outflow part 37, so that the possibility of winning in the start winning opening 17 is low.

Next, the operation and effect of this pachinko machine will be described with reference to FIGS.
The case where the pachinko ball (game ball) rolled on the game board (see FIG. 1) flows into the left inlet member 34a (FIG. 2 (a)) will be described. Since the center accessory 20 has a symmetrical structure, the same applies when it flows into the right inlet member 34b.

As shown in FIG. 3, the pachinko ball B (not shown in FIG. 3) that has flowed into the inlet member 34a is a rear-direction rolling part 52 (more precisely, a rear-direction rolling part 52) of the guide path forming member 50a. Roll in the back direction.
Thereafter, as shown in FIG. 4, the pachinko sphere B falls on the lower part 54 (more precisely, the path formed by the lower part 54 etc.), and the spiral rolling guide member 60a (its main body part 62). Flows into the interior.

Here, as described above, the substantially lower half of the flow part 54 is directed to the right side (the right side in the width direction of the pachinko machine) as it goes downward, that is, the spiral rolling guide member 60a ( Since it is bent from the upstream side to the downstream side of the main body 62), the pachinko ball B flows down along it.
For this reason, the pachinko ball B that has flowed into the spiral rolling guide member 60a (main body portion 62) is given a velocity component that moves vertically downward based on gravity, and in the right direction (downstream side). The heading speed component is given.

Then, as shown in FIG. 5, the pachinko sphere B rolls along the inner peripheral surface of the spiral rolling guide member 60a (main body portion 62) by energy based on gravity.
At the same time, as described above, the pachinko sphere B has a velocity component directed in the right direction, and therefore the pachinko sphere B tends to proceed in the right direction inside the spiral rolling guide member 60a (main body portion 62). . Further, as described above, the main body 62 of the spiral rolling guide member 60a is substantially horizontal, but more precisely, it is inclined from the horizontal so that it gradually goes downward from the left side toward the right side. The pachinko ball B tends to travel rightward in the spiral rolling guide member 60a (main body portion 62).
As a result, the pachinko ball B rolls in a spiral from the left side (upstream side) to the right side (downstream side) along the inner peripheral surface of the spiral rolling guide member 60a (main body 62). To do.

Then, the pachinko ball B gradually loses energy and becomes unable to perform the above-described helical rolling, and is shown by a one-dot chain line in FIG. 5A and as shown in FIG. 80 (the bowl-shaped portion 82a) or as shown by a two-dot chain line in FIG. 5 (a) and as shown in FIG. 7, the ball receiving member 80 (the bowl-shaped portion 82a) is not reached. The bottom part (reference numeral omitted) passes through the second outflow hole part 72 and reaches the outflow rolling part 48.
It should be noted that the number of spiral rolls made so far (which may be less than one round) and whether or not the ball receiving member 80 (the bowl-shaped portion 82a) is reached are determined by the spiral roll. It depends on the energy of the pachinko sphere B when it flows into the main body 62 of the guide member 60a.

As shown in FIG. 6, when the pachinko ball B reaches the bowl-shaped portion 82a (ball receiving member 80), the pachinko ball B rolls rightward along the bowl-shaped portion 82a, and rolls in the back direction. It rolls in the back direction at the moving part 84 and flows into the back side drop part 45 through the opening 46 for inflow. The pachinko ball B that has flowed into the back-side drop part 45 falls vertically down the back-side drop part 45, and reaches the outflow rolling part 48 through the outflow opening 47.
That is, the pachinko ball B reaches the center of the outflow rolling part 48 (the center in the width direction of the pachinko machine) from the back side. For this reason, the pachinko ball B rolls the central part of the outflow rolling part 48 along the depth direction toward the near side, and the central part of the outflow part 37 (the central part in the width direction of the pachinko machine) in the depth direction. Along the line and rolls down vertically from the outflow part 37.
For this reason, the pachinko ball B (first rolling outflow pattern) flowing out from the center accessory 20 through the outflow portion 37 through such a path is highly likely to win the start winning opening 17. That is, there is a high possibility that the special benefit described above is given to the player.

On the other hand, as shown in FIG. 7, when the pachinko sphere B reaches the outflow rolling part 48 from the bottom of the spiral rolling guide member 60a (main body part 62) through the second outflow hole part 72, The pachinko ball B rolls the outflow rolling part 48 to the obliquely front side shifted from the depth direction, and similarly rolls to the obliquely front side shifted from the depth direction in the outflow part 37 and obliquely from the outflow part 37. Fall down.
For this reason, the pachinko ball B (second rolling outflow pattern) flowing out from the center accessory 20 through the outflow portion 37 through such a path is unlikely to win the start winning opening 17. That is, it is unlikely that the special benefit described above is given to the player.

As described above, in this pachinko machine (center accessory 20), the pachinko ball B rolls spirally inside the spiral rolling guide member 60a (main body part 62) and passes through the main body part 62 having transparency. It is visually recognized by the player.
For this reason, this pachinko machine can give a player a great interest.

  Further, in this pachinko machine (center accessory 20), the pachinko ball B rolls spirally as described above based only on gravity, and does not require a motor, an electromagnet, etc., and does not require electrical wiring or the like. Therefore, the structure becomes simple and can be manufactured easily.

Further, depending on whether or not the pachinko ball B that has been spirally rolled as described above reaches the ball receiving member 80 (the bowl-shaped portions 82a and 82b), it will fall from the outflow portion 37 through which path thereafter. (I.e., whether to roll and flow out with the first rolling outflow pattern, or roll and flow out with the second rolling outflow pattern). Then, it depends on whether the pachinko ball B wins the start winning opening 17 and gives a special benefit to the player.
For this reason, whether or not the pachinko ball B reaches the ball receiving member 80 (the bowl-shaped portions 82a and 82b) after rolling in a spiral shape is of great interest to the player. In this pachinko machine, It can also give a big interest to the player in terms of points.

  Note that the above is merely an embodiment of the present invention, and it is needless to say that the present invention can be implemented in various modifications based on the knowledge of those skilled in the art.

  For example, in the above-described embodiment, the center accessory 20 has a symmetrical structure and a pair of spiral rolling guide members 60a and 60b are provided on the left and right, but the center accessory (20) is symmetrical. The structure may not be such that only one spiral rolling guide member may be provided.
