Description

  The present invention relates to a ball game machine in which a game is played using a game ball.

  In this specification, a pachinko machine is used as an example of a ball game machine, and therefore, a pachinko ball will be described as a game ball. However, a game ball other than a pachinko ball may be used as a game ball. Including. In addition, it is assumed that a pachinko ball enters a winning opening provided on the game board surface of the game board.

  Most pachinko machines having a symbol display device are provided with a stage having a rolling surface for rolling a pachinko ball launched into a game area of a game board. Generally, a start winning opening is provided below the stage, and the rolling surface is inclined so that pachinko balls that roll on the rolling surface can easily win the start winning opening. When a winning is generated at the start winning opening, the symbol display device is operated. Therefore, by providing the stage, it is possible to attract the interest of the movement of the pachinko ball that rolls on the rolling surface and to give a sense of tension to the game. However, simply by providing one stage, the movement of the pachinko ball rolling on the rolling surface is poor, and the game may become monotonous. For this reason, in recent years, for example, two stages are formed so that their heights are different from each other, or an electric movable object that moves a pachinko ball to a certain position by a magnet is provided to roll the rolling surface. There is a tendency to provide pachinko machines that have been devised in various ways to attract the player's interest in the movement of pachinko balls.

  However, with a two-stage configuration, the pachinko ball simply drops from the upper stage to the lower stage, so instead of the unique configuration of the two-stage stage, the movement of the pachinko ball Was scarce. Further, in the case where an electric movable object is provided, for example, when the power of the pachinko machine is cut off due to a power failure or the like, the pachinko ball may stagnate on the rolling surface, and the pachinko ball may be clogged.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a ball game machine that can change the movement of a game ball while dropping the game ball by its own weight. And

  In order to achieve the above object, the ball game machine of the present invention has a rolling surface inclined downward from the back side toward the near side, and a stage for rolling the game ball on the rolling surface. A gaming machine provided in a region, comprising a first protrusion that is pivotally supported about a substantially horizontal axis and protrudes above the rolling surface from below the stage before the stage. A swinging member and a biasing member that biases the first projecting portion in a direction approaching the stage. The swinging member projects toward the back side and is below the rolling surface. A second projecting portion capable of receiving a game ball dropped from a rolling surface is formed, and the swinging member swings in a direction in which the first projecting portion approaches the stage by the biasing of the biasing member. And the second protrusion is covered with the stage and the game ball dropped from the rolling surface The unacceptable position that cannot be received by the second protrusion, and the game ball that rolls on the stage causes the first protrusion to swing away from the stage against the bias of the biasing member. The second projecting portion swings between a receiving position where the second projecting portion is exposed and the game ball dropped from the rolling surface can be received by the second projecting portion.

  Further, it is preferable that an inclined surface inclined with respect to the axial direction of the shaft is formed on the second projecting portion.

  Moreover, it is preferable that the said urging | biasing member is a weight arrange | positioned so that the said axis | shaft may be rock | fluctuated.

  Moreover, it is preferable to provide a drop direction regulating wall for regulating the fall direction of the game ball dropped from the stage on the second protrusion.

  Further, the plurality of stages are arranged stepwise so that the heights thereof are different from each other, and the first projecting portion extends from the lower side of the stage provided at a relatively high position to the rolling surface. It is preferable to support the shaft so as to protrude further upward.

  Further, in the gaming machine of the present invention, the gaming board having a gaming area on which a game ball is launched on the front side and having a hole penetrating from the front side to the rear side, and the gaming board centered on a substantially horizontal axis And a first projecting portion projecting in a direction from the back side to the front side of the game board and a direction from the front side to the back side of the game board. A swing member formed with a second protrusion capable of receiving a falling game ball, and a bias for biasing the protrusion of the swing member in a direction from the front side to the back side of the game board And the swinging member swings in the direction from the front side to the back side of the game board by the biasing of the biasing member, and the second projecting portion is the hole. Projecting to the back side of the game board from the game board and receiving the game ball falling in the game area And the unacceptable position where the game ball falling in the game area presses the first protrusion, so that the first protrusion swings in the direction from the back side to the front side of the game board. The second projecting portion may swing between a receiving position where the second projecting portion projects from the hole toward the front side of the game board and can receive a game ball falling in the game area. Thereby, interest can be attracted to the movement of the pachinko ball falling in the game area.

  According to the present invention, the swinging member swings in a direction in which the first projecting portion approaches the stage by the biasing of the biasing member, and the second projecting portion is covered by the stage and falls from the rolling surface. And the unacceptable position where the second protrusion cannot receive, and the game ball rolling on the stage causes the first protrusion to swing away from the stage against the bias of the biasing member, and the second protrusion Since the game ball that has been exposed from the rolling surface and is exposed from the rolling surface is swung between the receiving position where it can be received by the second protrusion, the game ball can be dropped step by step. While falling due to its own weight, you can change the movement of the game ball.

  In addition, since the inclined surface inclined with respect to the axial direction is formed on the second projecting portion, it is possible to drop the gaming ball in the axial direction, and while the gaming ball is dropped by its own weight, Can change the movement.

  Since the urging member is a weight arranged so as to oscillate around the shaft, the urging member can be integrated with the oscillating member, reducing the number of parts and reducing the cost of the gaming machine. Can be reduced.

  In addition, since the falling direction regulating wall for regulating the falling direction of the game ball dropped from the stage is provided on the inclined surface of the second protrusion, it is possible to reliably drop the game ball in the axial direction of the swing member. It is possible to change the movement of the game ball with certainty.

  Further, the plurality of stages are arranged in a step shape so that the heights are different from each other, and the first protrusion protrudes above the rolling surface from below the stage provided at a relatively high position of the swing member. As a result, the time required for the game ball to roll on the rolling surface can be increased, and the player's interest in the movement of the game ball can be attracted.

  As shown in FIG. 1, a launch handle 10 a is provided below the pachinko machine 10. When the firing handle 10 a is operated, a pachinko ball is launched into the game area on the front side of the game board 11. A design display device 12 is incorporated in the game board 11. On the front surface of the game board 11, there are provided a start winning port 13, a normal winning port 14, a passing winning port 14a, an attacker 15, an out port 16, and the like, and the hit pachinko ball enters one of them. When a pachinko ball wins at the start winning opening 13, the symbol display device 12 displays a variation of the symbol and displays whether or not the player is advantageous. An accessory 18 having a stage 17 that temporarily rolls the pachinko ball that has been launched is provided below the symbol display device 12 and above the start winning opening 13.

  As shown in FIG. 2, the stage 17 has a two-stage configuration of a first stage 20 and a second stage 21 that are arranged in a stepped manner so that the heights are different from each other. The relative positions of the first stage 20 and the second stage 21 are set so that the first stage 20 is located above and the second stage 21 is located below.

  On the upper surfaces of the first stage 20 and the second stage 21, a first rolling surface 20a and a second rolling surface 21a for rolling a pachinko ball that drops the game ball are provided, respectively. The first rolling surface 20a and the second rolling surface 21a have the highest height at both ends, and are formed in a curved shape with a raised central portion.

  On both sides of the central portion of the first rolling surface 20a, inclined surfaces 20b and 20c are formed which are inclined from the back side to the near side, and an inclined surface 20d is formed at the center portion. In addition, inclined surfaces 21b and 21c that are inclined from the back side to the near side are formed on both sides of the central portion of the second rolling surface 21a, and inclined surfaces 21d that are inclined from the near side to the back side are formed in the central portion. ing. Each inclined surface 20b-20d, 21b-21d is formed in the substantially fan shape which the width | variety spreads gradually from the back side to the near side.

  The accessory 18 is connected to the first rolling surface 20a and the second rolling surface 21a, and includes a vertical surface 23 substantially perpendicular to these surfaces. A spherical entrance 24 is formed at a position of the vertical surface 23 facing the inclined surface 21b. In addition, a ball outlet 26 is formed on the vertical surface 25 that extends downward from the front of the second rolling surface 21a and is substantially perpendicular to the second rolling surface 21a so as to be positioned above the start winning opening 13. . The ball inlet 24 and the ball outlet 26 communicate with each other through a ball passage 27 formed inside the accessory 18. For this reason, the pachinko ball that has entered the ball inlet 24 passes through the ball passage 27 and is discharged from the ball outlet 26.

  In addition, three openings 28a to 28c are formed in the vertical surface 23 so as to be positioned below the inclined surfaces 20b to 20d. The opening 28a is disposed below the inclined surface 20b, the opening 28b is disposed below the inclined surface 20c, and the opening 28c is disposed below the inclined surface 20b.

  As shown in FIG. 3, from the openings 28a, 28c, there are first swing members (swing members) 29, 30 supported so as to be swingable around a substantially horizontal axis at the back of the openings 28a, 28c. Projecting in front of the first stage 20. Further, a second swing member (swing member) having a shape different from that of the first swing members 29 and 30 is pivotally supported from the opening 28b so as to be swingable about a substantially horizontal axis at the back of the opening 28b. 31 protrudes in front of the first stage 20.

  Next, the first oscillating members 29 and 30 will be described with reference to FIG. 4. Since the first oscillating member 29 and the first oscillating member 30 have the same configuration (left and right objects), the first oscillating member 29 and 30 will be described. The member 30 will be described as an example.

  The first swing member 30 includes a cylindrical bearing 40, a first projecting portion 41 projecting from the outer peripheral surface of the bearing 40, a second projecting portion 42 projecting from the first projecting portion 41, and a weight 43.

  The bearing 40 is pivotally supported at the back of the opening 28a so as to be swingable about a horizontal shaft 44.

  The first protrusion 41 is made of a rectangular plate, and protrudes from the outer peripheral surface of the bearing 40 so that its width direction is parallel to the axial direction A of the shaft 44 and its longitudinal direction is orthogonal to the axial direction A. The first projecting portion 41 has a length in the longitudinal direction so as to project from the lower side of the first stage 20 to the upper side of the first rolling surface 20a when the first swinging member 30 is located at an unacceptable position described later. Is set.

  The 2nd protrusion part 42 consists of a rectangular board with which the longitudinal direction curved. The 2nd protrusion part 42 protrudes so that it may orthogonally cross from the back surface 41a which is one of the wide surfaces of the 1st protrusion part 41. As shown in FIG. In a state where the first swing member 30 is attached to the accessory 18, the second projecting portion 42 projects toward the back side of the first rolling surface 20 a below the first stage 20.

  The upper surface of the second protrusion 42 is an inclined surface 42 a that is inclined with respect to the axial direction A of the shaft 44. The inclined surface 42a is sized to receive a pachinko ball, and when the back surface 41a of the first swing member 30 swings in the direction B away from the first stage 20, as will be described in detail later. Pachinko balls on the first rolling surface 20a fall on the inclined surface 42a.

  The falling direction of the pachinko sphere is set in the axial direction A at one end and the front end of the back surface 41a so as to be continuous with one side end of the inclined surface 42a in the rotation direction of the first swing member 30 and the side end. Are formed so as to protrude from the surfaces of each other. The falling direction of the pachinko ball on the inclined surface 42a is regulated by the fall direction regulating wall 45 and falls from the axial direction A (direction A in FIG. 4) to the second rolling surface 21a of the second stage 21. The pachinko ball received by the first swing member 29 falls to the left, and the pachinko ball received by the first swing member 30 falls to the right. If the fall direction regulating wall 45 is not provided, the pachinko balls can be dropped irregularly in the axial direction A. However, by providing the inclined surface 42a on the first swing member 30, the fall direction of the pachinko balls can be changed. It can be biased in a certain direction.

  The weight 43 is made of a fan-shaped plate and protrudes from the outer peripheral surface of the bearing 40 in a direction substantially opposite to the protruding direction of the first protruding portion 41. For this reason, the weight 43 swings around the shaft 44 as a fulcrum. The weight 43 and its protruding position from the bearing 40 are set so that the back surface 41a of the first protruding portion 41 is urged in the direction C approaching the first stage 20. Note that the weight 43 is caused by the weight of one pachinko ball received by the inclined surface 42a, causing the first swinging member 30 to swing away from the first stage 20, and the first swinging member 30 with its own weight. The weight is set to return to the initial position.

  Next, the second oscillating member 31 will be described with reference to FIG. 5, but the same members as those of the first oscillating member 30 are denoted by the same reference numerals and description thereof is omitted.

  The second rocking member 31 includes a first protrusion 50 protruding from the outer peripheral surface of the bearing 40 and a second protrusion 51 protruding from the first protrusion 50.

  The first projecting portion 50 is made of a rectangular plate, and projects from the outer peripheral surface of the bearing 40 so that its width direction is parallel to the axial direction A of the shaft 44 and its longitudinal direction is orthogonal to the axial direction A. The first protrusion 50 has a length in the longitudinal direction so as to protrude from below the first stage 20 above the first rolling surface 20a when the first swinging member 30 is located at an unacceptable position described later. Is set.

  The 2nd protrusion part 51 consists of a rectangular board with which the longitudinal direction curved, and protrudes from the back surface 50a which is one of the wide surfaces of the 1st protrusion part 50 so that it may orthogonally cross. In a state where the second swing member 31 is attached to the accessory 18, the second projecting portion 51 projects toward the back side of the first rolling surface 20 a below the first stage 20.

  The upper surface of the 2nd protrusion part 51 becomes the inclined surface 51a which inclines below from a base to a front-end | tip. The inclined surface 51a is connected to the back surface 50a. The inclined surface 51a is sized to receive a pachinko ball, and as will be described in detail later, the inclined surface 51a when the second swing member 31 swings in the direction B away from the first stage 20. Falls on the first rolling surface 20a.

  In addition, it is preferable that the width in the axial direction A of the inclined surfaces 42a and 51a and the distance by which the first rocking member 30 and the second rocking member 31 rock are not less than one and less than two pachinko balls. Accordingly, it is possible to prevent two or more pachinko balls from being received by the inclined surfaces 42 a and 51 a and clogging of the pachinko balls between the back surfaces 41 a and 50 a and the first stage 20. In addition, the maximum width of each of the inclined surfaces 20b to 20d and 21b to 21d is preferably 1 or more and less than 2 pachinko balls. As a result, a plurality of pachinko balls fall from each inclined surface at a time and two or more pachinko balls are received by the inclined surfaces 42 a and 51 a, and the pachinko balls are placed between the back surfaces 41 a and 50 a and the first stage 20. Can prevent clogging.

  The falling direction of the pachinko sphere is set to the both end portions and the tip portion of the back surface 50a so as to be connected to both end portions and the both end portions of the inclined surface 51a in the rotation direction of the second swing member 31. A drop direction regulating wall 45 that regulates in the projecting direction D is formed so as to project from each other. The pachinko balls received by the inclined surface 51a and the back surface 50a are guided to the back of the opening 28b by the drop direction regulating wall 45. The back of the opening 28 b communicates with the ball passage 27. For this reason, the pachinko ball that has fallen from the inclined surface 20 d and is guided by the second swing member 31 enters the ball passage 27.

  As shown in FIG. 6, the first rocking member 30 and the second rocking member 31 have an inclined surface 42a and an inclined surface 51a exposed, and pachinko balls are formed by the inclined surface 42a and the back surface 41a, and the inclined surface 51a and the back surface 50a. As shown in FIG. 7, the inclined surface 42a and the back surface 41a, and the inclined surface 51a and the back surface 50a are covered with the first stage 20, and the slanted surface 42a and the inclined surface 51a receive the pachinko balls. It swings between unacceptable positions where it cannot. Note that the pachinko ball can roll on the second rolling surface 21a when the first swinging member 30 and the second swinging member 31 are positioned at the receiving position, that is, the first swinging member 30 and the first swinging member 30. The relative relationship between the first rocking member 30, the second rocking member 31, and the second rolling surface 21a so that the distance between the two rocking member 31 and the second rolling surface 21a is larger than one pachinko ball. Distance is set.

  In the state where the first swinging member 30 and the second swinging member 31 receive the pachinko balls on the inclined surfaces 42a and 51a of the first swinging member 30 and the second swinging member 31, the first projecting portions 41 and 50 are provided. Back surfaces 41a and 50a are held in the receiving position in contact with the lower edges 28e of the openings 28b and 28c.

  Further, the first swinging member 30 and the second swinging member 31 swing in the direction C approaching the first stage 20 by the urging of the weight 43 when the slanted surfaces 42a and 51a are not receiving pachinko balls. The rear surfaces 41a and 50a abut against the front end surface of the first stage 20 (the upper edge 28f of the openings 28b and 28c) and are held at unacceptable positions.

  Next, the operation of the pachinko machine configured as described above will be described. Since the first swing member 29 and the first swing member 30 have the same operation, the first swing member 30 will be described with reference to the drawings. In a normal state, the first swing members 29 and 30 and the second swing member 31 are held at unacceptable positions by the weights of the respective weights 43. When the pachinko ball launched into the game area falls on the first rolling surface 20a, the fallen pachinko ball rolls on the first rolling surface 20a. When the pachinko ball on the first rolling surface 20a rolls on the inclined surface 20c, the pachinko ball rolls along the slope.

  Then, as shown in FIG. 8A, when the back surface 41a of the first protrusion 41 is pressed by the pachinko ball rolling on the inclined surface 20c, the first protrusion 41 is separated from the first stage 20 in the direction B. And the inclined surface 42a is exposed.

  After that, as shown in FIG. 8B, the exposed inclined surface 42a and the back surface 41a receive the pachinko balls that have dropped from the inclined surface 20c. At this time, the first swing member 30 is held at the receiving position. As shown in FIG. 9 (A), the falling direction of the pachinko ball received by the inclined surface 42a and the back surface 41a is regulated by the fall direction regulating wall 45, and from the axial direction A of the shaft 44 (the right side direction in FIG. 9). It falls on the second rolling surface 21a. As shown in FIG. 9B, when the pachinko ball falls, the first protrusion 41 is urged in the direction C approaching the first stage 20 by the weight of the weight 43 and swings. Then, as shown in FIG. 9C, the inclined surface 42a is covered with the first stage 20, and the first swing member 30 is held at the unacceptable position.

  As shown in FIG. 10A, pachinko balls on the first rolling surface 20a roll on the inclined surface 20d, and as shown in FIG. When the first protrusion 50 is pressed, the first protrusion 50 swings in the direction B away from the first stage 20, and the inclined surface 51a is exposed. Thereafter, as shown in FIG. 9C, the inclined surface 51a and the back surface 50a receive the pachinko balls dropped from the inclined surface 20d. At this time, the second swing member 31 is held at the receiving position. The pachinko balls received by the inclined surface 51a and the back surface 50a are regulated in the dropping direction by the dropping direction regulating wall 45 and fall in the projecting direction D (see FIG. 5) of the second projecting portion 51. The fallen pachinko ball enters the ball passage 27. Pachinko balls that have entered the ball passage 27 are discharged from the ball outlet 26. When the pachinko ball falls, the second swinging member 31 is held at an unacceptable position by the weight of the weight 43.

  In the above embodiment, the swinging member receives the game ball falling from the rolling surface of the stage. However, the swinging member may be attached to the game board to receive the pachinko ball falling in the game area.

  In this case, for example, as shown in FIG. 11, a hole 61 penetrating from the front side to the back side of the game board 60 is formed, and the swing member 62 so that the swing member 62 projects into the game area from the hole 61. Is pivotally supported on the game board 60. Note that the same reference numerals are used for the same portions of the swing member 62 as the first swing member 30, and description thereof is omitted. A main body 63 made of a rectangular plate protrudes from the outer peripheral surface of the bearing 40 of the swing member 62. A first projecting portion 64 projecting in a direction a from the back side to the front side of the game board 60 is provided at the upper end of the main body 63. The 1st protrusion part 64 consists of a board which curved upwards from the root to the front-end | tip, and the front-end | tip part protrudes about one pachinko ball in the game area | region.

  Further, a second protrusion 42 that is the same as the first swing member 30 is provided on the back surface of the main body 63. The second protrusion 42 protrudes in the direction b from the front side of the game board 60 toward the back side.

  In the swing member 62, the first protrusion 64 is urged by the weight 43 in the direction b from the front side to the back side of the game board 60. In the normal state, the swinging member 62 cannot receive the pachinko ball falling in the game area because the inclined surface 42a of the second protrusion 42 protrudes from the hole 61 to the back side of the game board 60 by the urging of the weight 43. It is held at an unacceptable position (position in FIG. 11).

  When the pachinko ball falling in the game area presses the upper surface of the first protrusion 64, the first protrusion 64 swings in the direction a from the back side to the front side of the game board 60. . As a result, the swinging member 62 can receive a pachinko ball from which the inclined surface 42a of the second protrusion 42 protrudes from the hole 61 to the front side of the game board 60 and falls in the game area from the unacceptable position. Swing to the position shown in FIG.

  A wall 65 that protrudes upward from the inclined surface 42 a is provided at the tip of the second protrusion 42. The wall 65 contacts the back surface of the game board 60 and covers the hole 61 when the swing member 62 swings to the receiving position. Thereby, it is possible to prevent the pachinko ball received on the back surface of the inclined surface 42a and the first projecting portion 64 from falling to the back side of the game board 60, and to allow the pachinko ball to fall irregularly in the game area. become.

  In the above-described embodiment, the swing member is composed of the first swing members 29 and 30 that drop the pachinko balls in the axial direction A and the second swing member 31 that drops the pachinko balls into the accessory 18.
