Description

  The present invention relates to a ball path unit and a gaming machine, and more particularly to a ball path unit and the like that can effectively decelerate a ball passing through a ball path.

  In a pachinko machine, a ball that has been bulleted flows down a game area (an area formed on or near the game board surface for realizing a game or production by the flow of the game ball). In the process of flowing down, the game ball turns while colliding with a game nail (also referred to as a gauge) or a windmill in the game area, and the flow direction changes. As a result, a predetermined prize ball is paid out when a game ball is won at various winning holes arranged on the game area, while a prize ball is paid out when a game ball flows into the out port without winning at any of the winning holes. Not done. The player enjoys the game by demonstrating his / her skill in the ball or using the chance of the game ball flowing down and expecting the game ball to be won and the prize ball paid out.

  In recent years, a gaming machine has been provided in which a center role is provided in the approximate center of a game board in which a game area is formed, and a ball path is provided in the center role. By providing the center passage with the ball passage, the player can enjoy the movement of the ball flowing down the game area and the movement of the ball passing through the ball passage. Further, in such a ball passage, there is provided one having a speed reduction mechanism for decelerating a passing sphere (see, for example, Patent Document 1 and Patent Document 2).

  For example, the ball passage described in Patent Document 1 includes a ladder member having a pair of support posts and a plurality of horizontal rails installed between the support posts, and a plurality of protrusions formed on the surface at predetermined intervals. And a wall member arranged opposite to each other. The ladder member and the wall member are arranged at intervals shorter than the diameter of the game ball so that the cross rails and the protrusions are alternated. The ladder member and the wall member form a passage for guiding the game ball. The spherical passage decelerates the passing sphere by the horizontal rail of the ladder member and the protrusion of the wall member.

  Further, the ball passage described in Patent Document 2 is constituted by a pair of wall surfaces arranged to face each other, and has a drop impact buffering plate protruding so as to be substantially perpendicular to the ball drop direction. The drop impact buffering plate is provided on each of the pair of wall surfaces. The drop impact buffer plate provided on one wall surface is provided substantially horizontally so as to face the other wall surface, and the drop impact buffer plate provided on the other wall surface is directed to one wall surface. It is provided substantially horizontally. Further, the drop impact buffer plate provided on one wall surface and the drop impact buffer plate provided on the other wall surface are arranged so as to be shifted in the vertical direction. The sphere passing through the ball passage falls while colliding with the drop impact buffer plate, and moves in a zigzag manner on one wall surface side and the other wall surface side to decelerate.

  The speed reduction mechanism in the ball passage described in Patent Literature 1 and Patent Literature 2 is arranged in the front-rear direction or the left-right direction of the sphere, and decelerates the sphere from two directions. However, when the momentum of the sphere is relatively high, it may not be possible to obtain a sufficient deceleration effect by simply decelerating from two directions. In order to enhance the speed reduction effect, it is conceivable to increase the number of speed reduction mechanisms installed. However, there may be a case where a sufficient space for the speed reduction mechanism cannot be obtained in a limited space of the ball passage.

  The present invention has been made in view of the above circumstances, and is a ball passage unit and a gaming machine having a speed reduction portion for reducing the speed of a ball passing through the ball passage, and increasing the speed reduction effect of the ball by the speed reduction portion. It is an exemplary problem to provide a ball passage unit or the like that can improve the degree of freedom of the arrangement of the deceleration unit.

  In order to solve the above problems, a ball passage unit as an exemplary aspect of the present invention includes an inflow port through which a sphere flowing down a game area flows in, an outflow port through which a sphere flowing in from the inflow port flows out, and an inflow port A sphere passage unit including a sphere passage that passes the sphere that has flowed in from the sphere passage toward the outlet, and a plurality of reduction portions that decelerate the sphere that passes through the sphere passage. On the other hand, it is comprised so that the four sides which are a side may be covered, and the deceleration part is arrange | positioned at the four sides.

  The sphere flowing in from the inflow port passes through the sphere passage and flows out from the outflow port. The spherical passage is provided so as to surround four sides that are lateral to the passing direction of the passing sphere, and a speed reduction portion is disposed in each of the four directions. The sphere passing through the spherical passage is decelerated by a speed reducing unit arranged on the side with respect to the passing direction. Since the ball passage unit configured in this manner decelerates from the four sides of the sphere, it is more effective than a ball passage unit in which a reduction portion is provided in two directions with respect to the sphere, such as the front and rear direction or the left and right direction of the sphere The ball can be decelerated.

  Moreover, since the speed reduction part is provided in the four directions which are side surfaces with respect to the passing direction of the sphere, it is easy to increase the number of speed reduction parts installed as compared with a ball passage provided with the speed reduction part in two directions with respect to the sphere. Furthermore, if the same number of speed reduction units are arranged in the configuration in which the speed reduction units are arranged in two directions with respect to the sphere and the configuration in which the speed reduction units are arranged in four directions, the configuration in which the speed reduction units are arranged in four directions arranges the speed reduction units. There are many possible areas, and the degree of freedom of arrangement of the speed reduction portions is increased.

  Furthermore, since the speed reduction parts are arranged in four directions with respect to the sphere, the number of speed reduction parts installed in the same length of the ball passage can be increased as compared with the configuration in which the speed reduction parts are arranged in two directions with respect to the sphere. Even if the ball passage has a relatively short length, the number of speed reduction units can be increased, and a high speed reduction effect can be obtained. That is, it is possible to increase the number of speed reducers installed with respect to the length of the ball path and shorten the length of the ball path required to obtain a desired speed reduction effect.

  Here, the four directions are around the passing sphere and are lateral to the passing direction of the sphere. Specifically, in a ball passage configured to pass a sphere in the vertical direction and cover the front, back, left, and right of the passing sphere, there are four directions, front, back, left, and right. However, the four directions in the present invention do not necessarily mean four directions. For example, in the case of a tube-shaped sphere passage, it is a concept including a circumference as an outer periphery of a passing sphere.

  Moreover, the deceleration part should just be arrange | positioned at all sides. For example, when the ball passage is provided so as to cover the four directions of front, rear, left, and right with respect to the ball, the speed reduction unit may be disposed in each of the front, rear, left, and right directions. Further, for example, in the case of a tube-shaped sphere passage, and the sphere passage is provided so as to cover the outer circumference 360 degrees that is lateral to the passing direction of the sphere, the outer circumference of the sphere extends over 360 degrees. It is preferable that the speed reduction part is arranged. Furthermore, the speed reduction part arranged in four directions may be formed integrally, or when the speed reduction part arranged in front of the sphere and the speed reduction part arranged on the left side are formed separately, etc. A plurality of deceleration parts may be formed separately. In other words, the speed reduction unit is a concept including any configuration that is arranged so as to exert a speed reduction effect in four directions that are lateral to the passing direction of the sphere.

  It is desirable that the speed reducers are arranged so that the intervals in the vertical direction are substantially constant. Since the speed reduction parts are arranged so that the distance in the vertical direction is substantially constant, the arrangement distance of the speed reduction parts can be varied according to the inclination of the spherical passage.

  Specifically, in the part where the slope is steep in the spherical passage, the distance in the vertical direction with respect to the passing distance of the sphere is longer than in the part where the slope is gentle, and many deceleration parts are arranged. In a portion where the inclination is steep, the speed of the sphere increases because the sphere suddenly descends. However, the speed of the sphere can be effectively reduced by a large number of speed reduction units. On the other hand, in the portion where the inclination is gentle, the distance in the vertical direction with respect to the passing distance of the sphere is shorter than in the portion where the inclination is steep, and the number of deceleration members is reduced. In the portion where the inclination is gentle, the speed of the sphere does not increase relatively, and a deceleration effect can be obtained by the deceleration units arranged in a small amount. That is, it is possible to effectively arrange the deceleration unit by arranging many deceleration units in a part where the speed of the sphere is likely to increase, and arranging a small number of deceleration units in a part where the speed of the sphere is not relatively increased. In addition, the vertical direction here is a vertical direction in a state where the ball path unit is attached to the gaming machine.

  The speed reduction part includes a first speed reduction part, a second speed reduction part, a third speed reduction part, and a fourth speed reduction part arranged adjacent to each other in four directions, and includes a first speed reduction part, a second speed reduction part, and a third speed reduction part. It is preferable that the fourth reduction part is configured to guide the passing sphere to the adjacent reduction part.

  The first deceleration unit, the second deceleration unit, the third deceleration unit, and the fourth deceleration unit can effectively decelerate the sphere from four sides that are lateral to the passing direction of the sphere. Since the first deceleration unit to the fourth deceleration unit are configured to guide the sphere to the adjacent deceleration unit, a plurality of deceleration units can continuously impart a deceleration effect to the passing sphere. The configuration in which the sphere is guided to the adjacent speed reducer is, for example, a sphere decelerated by the first speed reducer is guided to the second speed reducer, and the sphere guided to the second speed reducer is guided by the second speed reducer to the third speed reducer. It is the composition which leads to. In this way, by configuring the decelerated sphere to be guided to the adjacent decelerating portion, the passing sphere is continuously decelerated by the decelerating portion and effectively decelerates.

  Further, since the sphere is guided from the first deceleration unit to the adjacent deceleration unit by the fourth deceleration unit, the traveling direction of the sphere is a direction toward the adjacent deceleration unit. That is, the direction in which the sphere is guided by the deceleration unit and the traveling direction of the sphere are the same direction. For example, a deceleration unit that is arranged so as to prevent the progress of the sphere and decelerates the sphere by colliding with the sphere has a relatively large impact due to the collision of the sphere, and may be damaged by the collision of the sphere. There is. However, by configuring the speed reducer so as not to interfere with the traveling direction of the sphere, the impact of the speed reducer due to the collision of the sphere can be made relatively small, and damage to the speed reducer due to the collision of the sphere can be prevented.

  Furthermore, since the sphere passes through the sphere passage while moving in all directions, the trajectory of the sphere can be lengthened. As the passage trajectory becomes longer, the frictional force acting on the sphere increases and a further deceleration effect can be expected. For example, by disposing the adjacent first reduction gear, second reduction gear, third reduction gear, and fourth reduction gear in the vertical direction, the sphere passes while moving spirally. Can be relatively long.

  The first speed reduction portion and the third speed reduction portion are arranged to face each other in the ball passage, and the second speed reduction portion and the fourth speed reduction portion are arranged to face each other in the ball passage, In the projection plane, the distance between the end surface on the third speed reduction portion side in the first speed reduction portion and the end surface on the first speed reduction portion side in the third speed reduction portion is formed smaller than the diameter of the sphere, and the fourth speed reduction in the second speed reduction portion. It is desirable that the distance between the end face on the part side and the end face on the second speed reducing part side in the fourth speed reducing part is smaller than the diameter of the sphere.

  The first reduction part and the third reduction part are arranged to face each other, and the end face on the third reduction part side in the first reduction part and the end face on the first reduction part side in the third reduction part on the projection plane in the passing direction of the sphere When the ball passes between the first speed reduction part and the third speed reduction part, the ball surely contacts the first speed reduction part and the third speed reduction part. To do. Similarly, the second reduction part and the fourth reduction part are arranged to face each other, and on the projection surface in the passing direction of the sphere, the end face on the fourth reduction part side in the second reduction part and the second in the fourth reduction part. By forming the distance from the end face on the speed reduction part side smaller than the diameter of the sphere, when the sphere passes between the second reduction part and the fourth reduction part, the sphere is surely connected to the second reduction part and It contacts the fourth reduction part. The ball is reliably decelerated by the deceleration unit by reliably contacting the deceleration unit when the ball passes.

  Further, the distance between the end surface on the third speed reduction portion side in the first speed reduction portion and the end surface on the first speed reduction portion side in the third speed reduction portion, the end surface on the fourth speed reduction portion side in the second speed reduction portion, and the fourth speed reduction portion By setting the distance from the end surface on the second speed reduction portion side to be substantially the same distance, the passage width in the spherical passage can be made substantially constant. When the passage width in the sphere passage is smaller than the diameter of the sphere and has a constant dimension, the sphere can be in uniform contact with each reduction portion, and the sphere can be uniformly decelerated from four directions. Furthermore, when the passage width in the ball passage is smaller than the diameter of the ball and has a constant dimension, there is no space for the ball to escape in the ball passage, and the ball can be decelerated continuously in the process of passing through the passage. .

  In addition, a gaming machine as another exemplary aspect of the present invention includes a gaming board unit in which a gaming area for realizing gaming by flowing down a gaming ball is formed, the above-described ball path unit, and the gaming board unit. And a ball passage unit is arranged so that a ball flowing down the game area can flow into the ball path unit.

  According to this gaming machine, the ball flowing down the game area formed in the game board unit can be effectively decelerated by the ball path unit. Compared with the configuration in which the speed reducing portions are provided in two directions with respect to the sphere by providing the speed reducing portions in the four directions lateral to the passing direction of the sphere, the number of speed reducing portions to be installed with respect to the passage length of the sphere in the spherical passage is reduced. Can be increased. Therefore, the length of the ball passage necessary for obtaining a desired deceleration effect can be shortened, and the arrangement space of the ball passage unit in the game board unit can be reduced.

  The gaming machine frame is a frame member or a group of frame members that encloses the gaming apparatus body and surrounds the side and front of the gaming apparatus body. For example, when the gaming machine is a pachinko gaming machine, a housing frame, a machine frame, a front frame, a combination thereof, or the like that includes a gaming board as a gaming device body corresponds to the gaming machine frame.

  Further objects and other features of the present invention will become apparent from the preferred embodiments described below with reference to the accompanying drawings.

  According to this invention, the deceleration part is arrange | positioned at the four directions which are a side with respect to the passage direction of a sphere, and the deceleration effect by a deceleration part can be provided with respect to a sphere from four directions. Moreover, since the area | region which can install a deceleration part increases compared with the ball channel | path provided with the deceleration part in two directions with respect to a ball | bowl, the freedom degree of the arrangement space of a deceleration part can be improved. Therefore, it is possible to increase the number of speed reducers installed with respect to the length of the ball passage and shorten the length of the ball passage required to obtain a desired speed reduction effect.

The sphere 23 guided to the second protrusion 45b by the first protrusion 45a is guided to the right through the rear from the left of the passage region. On the right side of the passage area of the sphere, the second protrusions 45b and the third protrusions 45c are alternately arranged in the vertical direction, and the sphere 23 guided to the right by the second protrusion 45b The third protrusion 45c disposed below is guided from the right to the left where the first protrusion 45a is disposed through the front. Thus, the sphere 23 can be guided from the first protrusion 45a to the second protrusion 45b and from the second protrusion 45b to the third protrusion 45c.

  On the other hand, the sphere 23 guided from the first protrusion 45a to the third protrusion 45c is guided to the right through the front from the left of the passage region. And it guide | induces to the left from the right through the back by the 2nd projection part 45b arrange | positioned under the 3rd projection part 45c. Thus, the sphere 23 is guided from the first protrusion 45a to the second protrusion 45b, the sphere 23 is guided from the second protrusion 45b to the third protrusion 45c, and the third protrusion from the first protrusion 45a. Since the sphere 23 is guided to the portion 45c and the sphere 23 is guided from the third protrusion 45c to the second protrusion 45b, the continuous deceleration by the plurality of protrusions with respect to the passing sphere 23 is achieved. An effect can be imparted.

  Moreover, the 2nd protrusion part 45b and the 3rd protrusion part 45c which were provided in the cover part 43b protrude toward the inner side from the inner wall face. Furthermore, the part along the left-right direction of the 2nd projection part 45b is formed in the same shape, and the part along the left-right direction of the 3rd projection part 45c is formed in the same shape. Thus, since the 2nd protrusion part 45b and the 3rd protrusion part 45c are formed, when forming the cover part 43b, it is possible to integrally form the cover part 43b by moving a type | mold to the left-right direction. is there. Since the cover part 43b can be integrally formed, the number of parts of the cover part 43b can be reduced, and the manufacturing process can be shortened.

  Thus, according to the warp passage 40 according to the present embodiment, the sphere that has flowed from the inflow port 41 can be effectively decelerated from the four sides that are lateral to the passage direction. Further, the portion near the outflow port 44 of the second ball passage 43 is configured such that the number of protrusions is less than that of the upper portion, and the ball flows out to the stage portion 7f at a certain speed. Accordingly, the sphere that has flowed out of the outlet 44 is guided to the stage portion 7f at a predetermined speed, and swings in the left-right direction on the stage portion 7f. Then, a certain ball that has swung the stage portion 7f is guided to the starting port unit 29 disposed below, and the certain ball flows down the game area 16 again.

  Next, the game flow of the pachinko machine 2 will be described. When the ball 23 is launched by a ball launching device (not shown), the ball 23 travels along the inner peripheral surface of the rail decoration and reaches the upper part in the game area 16. Thereafter, the ball 23 moves along a plurality of passing trajectories and flows down the game area 16 while colliding with the game nail. Some pass through the warp passage 40 and swing the stage portion 7f and then flow into the first starting port 29a to trigger a certain number of prize ball payouts, and some do not flow into any winning port. It flows into the out port 30 located at the lowermost part in the game area and is discharged to the outside of the pachinko machine 2 as an out ball.

  When the ball 23 enters the first starting port 29a, the first symbol 17b is displayed on the first symbol display unit 17, and an effect display including the first decorative symbol 7d is made in the first game area 7b of the effect display device 7a. The When the ball 23 enters the second starting port 29b, the second symbol 18b is displayed on the second symbol display unit 18, and an effect display including the second decorative symbol 7e is made in the second game area 7c of the effect display device 7a. The

  The display of the first symbol 17b, the second symbol 18b, the first decorative symbol 7d, and the second decorative symbol 7e stops after a predetermined time has elapsed from the start of the change. When the first symbol 17b and the first decorative symbol 7d are stopped in a predetermined winning manner, a transition is made to the first special game which is a gaming state advantageous to the player, and the opening / closing operation of the central special winning opening 31 is started. Further, when the second symbol 18b and the second decorative symbol 7e are stopped in a predetermined winning manner, the game shifts to the second special game which is a game state advantageous to the player, and the opening / closing operation of the central special winning opening 31 is started. . The central grand prize opening 31 is opened to accept a large amount of winning balls, and a large amount of prize balls are paid out to the storage tray 14.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these, A various deformation | transformation and change are possible within the range of the summary.
