Description

  The present invention relates to a gaming machine that uses a ball (pachinko ball) to play a game, such as a pachinko machine, an arrange ball machine, a sparrow ball game machine, and the like.

Conventionally, in this type of gaming machine, it is formed in a horizontal rectangular box shape having a volume that can store a large number of balls and opening upward at the rear upper part of the gaming machine in which the gaming board is mounted on the gaming board mounting frame. A fitted ball tank is installed. And the supply area | region where a ball | bowl is supplied from the sphere supply path of an island installation is set in the part near one end of the longitudinal direction of the bottom face of a ball tank, and the other end of the longitudinal direction which leaves | separates from a supply area | region to the bottom face of the ball tank The part is provided with a discharge port.
The bottom surface of the sphere tank is inclined such that one end in the longitudinal direction is high and the other end is low, and the sphere supplied to the supply region flows toward the discharge port.
On the rear side of the gaming machine, an inclined tank rail that is positioned below the ball tank and guides the ball discharged from the discharge port of the ball tank to the ball path of the ball dispensing device is disposed.
In the sphere tank having the structure as described above, the sphere tank is empty or nearly empty, and a large amount of spheres are supplied to the supply area of the sphere tank from the sphere supply path of the island facility in a short time. As a result, the large number of spheres flow all at once toward the outlet. In the vicinity of the discharge port, there is a case where a ball clogging occurs due to a bridge phenomenon.
In addition, even when a large amount of spheres are stored in the sphere tank and the sphere tank is full or nearly full, the sphere pressure of a large amount of spheres acts on the sphere near the discharge port of the sphere tank, and the clogging occurs due to the bridge phenomenon. May occur.
In order to reduce such clogging, for example, there is one in which a protrusion (sometimes referred to as a ball collapse) is formed in the vicinity of the discharge port.
Furthermore, in addition to the projecting body, a step portion is formed with a step height that extends in the longitudinal direction of the bottom surface of the sphere tank and is smaller than the radial dimension of the sphere, and flows through the center height of the sphere flowing through the lower inclined surface and the upper inclined surface. What shifted | deviated from the center height of a ball | bowl is known (for example, refer patent document 1).

By the way, in the conventional bottom structure of the sphere tank described above, the lower inclined surface located at the center of the bottom surface of the sphere tank has a central portion of the supply region near one end thereof, and is below the lower inclined surface. The inclined end extends continuously to the discharge port.
For this reason, if a large amount of spheres are supplied to the supply area of the sphere tank from the sphere supply path of the island facility in a short time, the sphere tank becomes empty or nearly empty. However, there is a case where a ball clogging occurs due to a bridge phenomenon in the vicinity of the discharge port by flowing along the lower inclined surface toward the discharge port all at once.
In addition, even when a large amount of spheres are stored in the sphere tank and it is full or nearly full, the sphere pressure of a large amount of spheres existing on the lower inclined surface acts on the sphere near the discharge port, and the bridge Depending on the phenomenon, ball clogging may occur, and the effect of preventing ball clogging is small.

  In view of the above problems, the object of the present invention is to prevent the sphere pressure in the sphere tank from concentrating on the sphere in the vicinity of the discharge port and to prevent the occurrence of sphere clogging due to the bridge phenomenon. To provide a gaming machine having a ball tank structure that can be prevented.

In order to achieve the object, a gaming machine according to the invention of claim 1

In the above configuration, the ball tank is in an empty state or nearly empty, and a large amount of spheres are formed in a short time from the island supply sphere supply path with respect to the supply area existing on one inclined surface of the sphere tank. When supplied, some of the large number of spheres pass through the boundary valley from one inclined surface. Then, the sphere that has passed through the boundary valley portion climbs the other inclined surface while slowing down the speed, and then flows down the other inclined surface and is discharged from the discharge port to the tank rail.
In addition, a part of the spheres abut on the contact surface of the projecting body on one inclined surface, and then rebound from the contact surface or flow along the contact surface and pass through the boundary valley. Then, the sphere that has passed through the boundary valley portion climbs the other inclined surface while slowing down the speed, and then flows down the other inclined surface and is discharged from the discharge port to the tank rail.
For this reason, even if a large amount of spheres are supplied to the supply region existing on one inclined surface of the sphere tank in a short time, the spheres do not flow toward the discharge port all at once. For this reason, generation | occurrence | production of ball | bowl clogging can be prevented favorably by the bridge | bridging phenomenon in the discharge port vicinity.
Further, when a large amount of spheres are stored in the sphere tank and are in a full or nearly full state, a part of the large number of spheres is received in contact with the contact surface of the protrusion. That is, a large amount of spheres stored in the sphere tank are reduced by the contact surfaces of the protrusions.
For this reason, it is possible to prevent the ball pressure of a large amount of spheres from acting on the sphere in the vicinity of the discharge port, and it is possible to satisfactorily prevent the occurrence of clogging due to the bridge phenomenon.
Further, by reducing the ball pressure of a large number of balls in the ball tank by the contact surface of the projecting body, the ball pressure acting on the balls in the tank rail can be reduced accordingly.
As a result, it is possible to prevent the balls in the tank rail from overlapping with each other and spilling from the rear wall of the tank rail.
In other words, the height of the rear wall of the tank rail can be kept small, and by this amount, the height of the tank rail is set higher with respect to the rear side of the gaming machine, and the other side of the tank rail Space for arranging members, equipment and the like can be secured.

A lower contact surface and an upper contact surface for guiding the sphere in the direction of the boundary valley are formed on the lower and upper standing wall portions of the projecting body,
The gaming machine, wherein the lower contact surface and the upper contact surface have a height dimension larger than a radius dimension of a sphere. ".

  In the above configuration, the lower contact surface and the upper contact surface of the projecting body formed in a step shape having a low supply region side and a high discharge port side have a height dimension larger than the radial dimension of the sphere. It is possible to reduce the ball pressure by reliably receiving the spheres on the contact surface and the upper contact surface. Furthermore, in the process of decreasing the sphere in the ball tank from being almost full, first, the ball received by the upper contact surface flows into the discharge port, and then the ball received by the lower contact surface becomes the discharge port. Because it flows, the flow of the sphere becomes smooth.

According to the present invention, even if a large amount of spheres are supplied to the supply region existing on one inclined surface of the sphere tank in a short time, the spheres do not flow toward the discharge ports all at once. The occurrence of clogging of the balls can be satisfactorily prevented by the bridge phenomenon in the vicinity of the discharge port.
Further, the ball pressure of a large amount of balls in the ball tank can be reduced by the contact surface of the protrusion, and the ball pressure acting on the balls in the tank rail can be reduced accordingly.
For this reason, it is possible to prevent the ball pressure of a large amount of spheres from acting on the sphere in the vicinity of the discharge port, and it is possible to satisfactorily prevent the occurrence of clogging due to the bridge phenomenon.

The bottom surface (bottom plate portion) 166 of the sphere tank 165 is formed with a discharge port 168 that is located at or near a corner portion away from the supply region P and discharges the sphere B toward the tank rail 175. In this embodiment, a discharge port 168 is formed at the rear corner of the bottom surface 166 of the ball tank 165.
On the bottom surface 166 of the sphere tank 165, an oblique line from the vicinity of the corner portion in the vicinity of the discharge port 168 to the discharge port 168 is defined as a boundary valley portion 166a, and the boundary valley portion 166a extends from the peripheral portion of the bottom surface 166. The first and second inclined surfaces 166b and 166c are formed so as to incline downward toward the surface and have an inclined shape with a high diagonal side and a low discharge port 168 side.

As shown in FIGS. 15 and 16, the flow of the sphere B flows on the first inclined surface 166b of the first and second inclined surfaces 166b and 166c of the ball tank 165 where the central portion of the supply region P exists. A protrusion 170 is provided to prevent the clogging of the discharge port 168 and the vicinity thereof by restricting the above.
As shown in FIGS. 15 and 16, the projecting body 170 is located between the discharge port 168 and the supply region P and exists from the inner surface of the rear wall 167a of the ball tank 165 to the vicinity of the boundary valley 166a, and has a planar shape.

As a result, the sphere B in contact with the contact surface 170a is reliably guided in the direction of the boundary valley 166a, and the sphere B is prevented from stopping and staying in contact with the contact surface 170a. It has become.
Further, the height of the standing wall-like contact surface 170a is set to a height dimension larger than the radial dimension of the sphere B, for example, approximately two to three times the diameter dimension of the sphere B.
In addition, the protrusion 170 may be formed integrally with the ball tank 165 at the same time as the ball tank 165 is formed of a synthetic resin material. It may be attached by means.

[About the tank rail]
As shown in FIGS. 6 and 7, a tank rail 175 is arranged on the mechanism mounting portion 160 on the rear side of the main body frame 30 so as to be connected to the lower side of the ball tank 165. The tank rail 175 receives the ball B discharged from the discharge port 168 of the ball tank 165, and the ball dispensing device in which the ball B is arranged in the vertical direction on one side (right side in FIG. 6) of the mechanism mounting portion 160. It is guided to the ball passage 210a of 210, and has an inclined shape in which the discharge port 168 side is high and the ball dispensing device 210 side is low.
In this embodiment, as shown in FIG. 7, the front wall 175a of the tank rail 175 and the rail receiving portion 175b are integrally formed in a part of the mechanism mounting portion 160 so as to have a substantially L-shaped cross section. The tank rail 175 is configured by mounting the rail structure 176 on the tank.
The rail constituting body 176 is integrally formed with a rear wall 176a of the tank rail 175 and a rail portion 176b supported on the rail receiving portion 175b, and is formed in an inverted L shape in cross section, and on the rail portion 176b. A partition wall 176c extending in the rail direction protrudes, thereby forming a front and rear two rows of rail passages.

As shown in FIG. 7, the front wall 175 a of the tank rail 175 avoids interference with equipment protruding toward the rear side of the game board 40, for example, the upper end portion of the rear portion 47 a of the accessory body 47 of the accessory device 46. For this reason, the first space portion S1 is provided in a separated state.
In this embodiment, the rear wall 176a of the tank rail 175 is substantially flush with the rear wall 167a of the ball tank 165.
In other words, the tank rail 175 is arranged behind the rear surface of the game board 40 so that the rear wall 176a of the tank rail 175 is substantially flush with the rear wall 167a of the ball tank 165. As a result, a first space S1 for avoiding interference with the rear portion 47a of the accessory body 47 of the accessory device 46 is provided between the rear surface of the game board 40 and the front wall 175a of the tank rail 175. ing.
Further, in this embodiment, as shown in FIGS. 6 and 7, the upper end of the rear wall 176a of the tank rail 175 is the lower end of the rear wall 167a of the ball tank 165 in the portion located on the discharge port 168 side of the ball tank 165. It is arranged in contact with or close to.

[Regarding the rectifier of the tank rail]
As shown in FIGS. 6 and 17, a part of the mechanism mounting portion 160 on the rear side of the main body frame 30 includes a ceiling portion 180 having an inclined shape above the tank rail 175 and having a high upstream side of the tank rail 175 and a low downstream side. Is formed. A rectifier mounting recess 181 that is recessed upward is formed at a predetermined position of the ceiling portion 180 (a position corresponding to the downstream side portion of the rail passages in the two rows before and after the tank rail 175).
A pair of front and rear rectifying bodies 190 (sometimes referred to as a sphere leveling body) are mounted on the rectifying body mounting recess 181 so as to be swingable about a common shaft 191 at their upper ends. These pair of rectifying bodies 190 are each provided with a single or a plurality of weights 192 such as a sphere at the bottom thereof so as to form a substantially hanging shape by their own weight. And the lower end part of a pair of rectification | straightening body 190 has faced the space which can pass each one ball | bowl B above the rail path of two rows before and behind the tank rail 175, respectively. As a result, when the spheres B flowing in the rail passages in the two front and rear rows of the tank rail 175 flow in a vertically stacked state, the upper sphere B is smoothed by the rectifier 190.
In other words, by preventing the spheres B flowing in the two rail lines in the front and rear rows of the tank rail 175 from being stacked vertically, the pair of rectifiers 190 prevents the spheres B on the downstream side of the rectifiers 190. Are arranged in a row and flow.

As shown in FIG. 17, the rectifier mounting recess 181 is allowed to rotate until the pair of front and rear rectifiers 190 are substantially horizontal in the direction toward the downstream side of the two rail rail paths of the tank rail 175. It is formed in the shape to do. In other words, by allowing the pair of front and rear rectifying bodies 190 to rotate to the position where they are stored in the rectifying body mounting recess 181, the protruding portion of the rectifying body 190 is possible below the general part 180 a of the ceiling part 180. Has been reduced.
As described above, the pair of front and rear rectifiers 190 are configured to be retractable in the rectifier mounting recess 181 so that the ball B is excessively stored in the rail passage of the tank rail 175. The pair of front and rear rectifiers 190 are rotated by the flow pressure of these spheres B in the direction toward the downstream side of the two front and rear rail passages of the tank rail 175 to the retracted state centered on the shaft 191 and substantially horizontal.

In other words, in this embodiment, the pair of front and rear rectifiers 190 are stored in the rectifier mounting recess 181 without protruding below the general part 180 a of the ceiling part 180. For this reason, even when the ball B is excessively stored in the rail passage of the tank rail 175, it is possible to prevent a problem that the ball B spills from the tank rail 175.
For example, when the rotation angle of the pair of front and rear rectifying bodies 190 is limited to be small when hitting the ceiling portion 180 forming the upper side wall of the rail mounting recess 230, and a part of the rectifying body 190 protrudes greatly from below the ceiling portion 180, The flow of the sphere B is obstructed by the protruding portion of the rectifying body 190. As a result, when the ball B is excessively stored in the rail passage of the tank rail 175, there may be a problem that the ball spills from the rail passage of the tank rail 175.
However, according to this embodiment, it is possible to prevent the problem that the ball B spills from the rail passage of the tank rail 175 as described above.

In particular, as shown by a two-dot chain line in FIG. 17, in a state where the rectifying body 190 is rotated to a position where it is stored in the rectifying body mounting recess 181, one side surface of the general portion 180 a of the ceiling portion 180 and the rectifying body 190. (Side surface abutting on the sphere B) 190a is substantially the same surface, and the downstream lower end edge of the rectifying body mounting recess 181 and one end surface of the rectifying body 190 (side surface abutting on the sphere B) 190a The shape of the rectifying body mounting recess 181 and the rectifying body 190 is set so that the gap between them is very small. That is, one side surface 190a of the rectifying body 190 (side surface contacting the sphere B) is formed in a substantially flat surface from one end to the other end, and is rotated to a position where the rectifying body 190 is stored in the rectifying body mounting recess 181. In such a state, one side surface 190a of the rectifying body 190 is configured to form the same surface that is continuous with the general portion 180a of the ceiling portion 180 without a substantial gap.
As a result, in a state where the rectifying body 190 is rotated to the position where it is stored in the rectifying body mounting recess 181, the ball B hits the lower end edge on the downstream side of the rectifying body mounting recess 181, resulting in a problem that a ball clogging occurs. It has been resolved.
In other words, for example, when the tip of the rectifier mounting recess 181 is formed in an arc shape, the rectifier 190 is stored in the rectifier mounting recess 181 in the state where the rectifier mounting recess 181 is stored. There is a case where a gap is formed between the tip and the lower end edge of the rectifying body mounting recess 181, and the sphere B hits the lower end edge on the downstream side of the rectifying body mounting recess 181, which may cause clogging. According to this embodiment, ball clogging can be prevented well.

[Other configuration of the mechanism mounting part on the rear side of the body frame]
As shown in FIG. 3, a ball dispensing device 210 that is unitized in a vertically long shape is mounted in the vertical direction near the one side (right side as viewed in FIG. 3) of the mechanism mounting portion 160 of the main body frame 30.
Further, as shown in FIG. 10, a second space portion S2 is provided between the ball payout device 210 of the mechanism mounting portion 160 and the game board 40 at substantially the same level as the first space portion S1 in the front-rear direction. Yes. The rear surfaces of the ball tank 165, the tank rail 175, and the ball dispenser 210 are substantially the same.

  Further, in this embodiment, as shown in FIG. 3, a lower inclined end portion of the firing rail 100 is provided on one side (left side as viewed in FIG. 3) of the lower region of the mechanism mounting portion 160 on the rear side of the body frame 30. A launching device unit 230 having a firing hammer 233 for firing a ball sent to the firing position, a firing motor 232 for operating the firing hammer 233, and the like is mounted. Further, a power supply board box 240 having a power supply board and a frame control board box 234 having a frame control board are mounted in the center of the lower region of the mechanism mounting section 160 in a state where they are overlapped in the front-rear direction.

[Operation and effect of embodiment]
In the gaming machine according to this embodiment configured as described above, as shown in FIGS. 15 and 16, the first inclined surface 166 b where the central portion of the supply region P of the ball tank 165 exists has a discharge port. A projecting body 170 is provided between the rear wall 167a of the ball tank 165 and the vicinity of the boundary valley 166a. The projecting body 170 is formed with a standing wall-like contact surface 170a that stands up toward the supply region P and receives the sphere B and guides the sphere B in the direction of the boundary valley 166a.
Therefore, as shown in FIG. 15, when the inside of the sphere tank 165 is empty or nearly empty, the sphere supply path of the island facility is supplied to the supply area P existing on the first inclined surface 166b of the sphere tank 165. When a large amount of spheres B are supplied in a short time, some of the spheres B pass through the boundary valley 166a from the first inclined surface 166b. Then, the sphere B passing through the boundary valley 166a goes up the second inclined surface 166c while slowing down, flows down the second inclined surface 166c, flows into the discharge port 168, and is discharged to the tank rail 175. The
Further, after a part of the sphere B comes into contact with the contact surface 170a of the projecting body 170 of the first inclined surface 166b, it rebounds from the contact surface 170a or flows along the contact surface 170a. It passes through the valley 166a. Then, the sphere B that has passed through the boundary valley portion 166a goes up the second inclined surface 166c while slowing down, flows down the second inclined surface 166c, flows into the discharge port 168, and is discharged to the tank rail 175. Is done.
For this reason, even if a large amount of spheres B are supplied to the supply region P existing on the first inclined surface 166b of the sphere tank 165 in a short time, the spheres B flow toward the discharge port 168 all at once. Therefore, the occurrence of clogging of the balls can be satisfactorily prevented by the bridging phenomenon in the vicinity of the discharge port 168.

Further, when a large amount of spheres B are stored in the sphere tank 165 and are in a full state or almost full, a part of the large amount of spheres B comes into contact with the contact surface 170a of the projecting body 170 and is received. That is, a large amount of the sphere B stored in the sphere tank 165 is reduced by the contact surface 170 a of the protrusion 170.
For this reason, it is possible to prevent the ball pressure of a large amount of the sphere B from acting on the sphere B in the vicinity of the discharge port 168, and it is possible to satisfactorily prevent the occurrence of the sphere clogging due to the bridge phenomenon.
Further, by reducing the ball pressure of a large amount of balls B in the ball tank 165 by the contact surface 170a of the protrusion 170, the ball pressure acting on the balls B in the tank rail 175 is also reduced by this amount. be able to.
As a result, it is possible to prevent the balls B in the tank rail 175 from overlapping with each other and the upper-layer balls B from falling from the rear wall 176a of the tank rail 175.
In other words, the height dimension of the rear wall 176a of the tank rail 175 can be kept small, and accordingly, the height of the tank rail 175 is set higher with respect to the rear side of the gaming machine, and the tank rail 175 is placed below the tank rail 175. On the other hand, it is possible to secure a space for arranging other members, equipment and the like.

  The discharge port 168 formed in the bottom surface 166 of the ball tank 165 is disposed at the rear corner of the bottom surface 166, and the rear wall 176a of the tank rail 175 is substantially flush with the rear wall 167a of the ball tank 165. A first space S <b> 1 is provided between the front wall 175 a of the rail 175 and the rear surface of the game board 40. For this reason, the rear portion 47a of the accessory main body 47 of the accessory device (center accessory device) 46 provided with the large display device is used as the rear portion of the various accessory items and the large display device. 1 space part S can be protruded and arranged in the space part. As a result, the freedom degree of arrangement design of the various actors and the large display device with respect to the game board 40 can be increased.

  Further, the upper end of the rear wall 176a of the tank rail 175 is disposed in contact with or close to the lower end of the rear wall 167a of the ball tank 165 in the portion located on the discharge port 168 side of the ball tank 165. For this reason, the arrangement height of the tank rail 175 can be set high, and a space for arranging other members, equipment, etc. can be secured below the tank rail 175.

[About other embodiments]
In addition, this invention is not limited to the said Example.
For example, in the above embodiment, the case where the discharge port 168 is formed at the rear corner portion of the bottom surface 166 of the ball tank 165 is illustrated, but as shown in FIG. The present invention can be implemented even when the discharge port 168 is formed.
However, in this case, on the bottom surface 166 of the ball tank 165, an oblique line from the vicinity that forms a diagonal portion with the front corner portion to the discharge port 168 serves as a boundary valley portion 166a, and from the peripheral edge portion of the bottom surface 166 to the boundary valley portion. First and second inclined surfaces 166b and 166c are formed which incline downward toward 166a and have an inclined shape in which the diagonal portion side is high and the discharge port 168 side is low.
Then, on the first inclined surface 166b where the supply region P exists, it exists between the supply region P and the discharge port 168 and exists from the inner surface of the front wall 167e of the ball tank 165 to the vicinity of the boundary valley portion 166a, And the protrusion 170 which has the standing wall-like contact surface 170a is provided.

Further, as shown in FIG. 19, the projecting body 170 may be formed in a stepped shape that is low on the supply region P side and high on the discharge port 168 side.
That is, the protrusion 170 has a lower contact surface 170b and an upper contact surface 170c that guide the sphere B in the direction of the boundary valley 166a, and the lower contact surface 170b and the upper contact surface 170c are It has a height dimension larger than the radius dimension of the sphere B.
As described above, the projecting body 170 is formed in a stepped shape having a low supply region P side and a high discharge port 168 side, thereby reliably receiving the sphere B on the lower contact surface 170b and the upper contact surface 170c. Can reduce the ball pressure.
Further, in the process of decreasing the sphere B in the sphere tank 165 from being almost full, first, the sphere B received by the upper contact surface 170c flows to the discharge port 168 and then received by the lower contact surface 170b. Since the sphere B flows to the discharge port 168, the flow of the sphere B is smoothed.

Moreover, in the said Example, the main body frame 30 attached to the front surface of the outer frame 10 so that opening and closing was possible was a conventional front frame (it may be called an inner frame, a front frame etc.), and a mechanism board (back mechanism board).
