Description

  The present invention relates to a pachinko gaming machine in which a game board is provided with a ball stop member that decelerates a game ball that is launched into a game area by colliding with the game ball.

A game board of a conventional pachinko machine is provided with an outer rail that guides a game ball launched from a launcher to a game area. In the game area, a ball stopper rubber that collides a game ball guided by the outer rail and depresses the ball is disposed near the end of the outer rail. The ball stopper rubber is formed in a rectangular shape, and a reflection surface portion, which is one side surface portion thereof, is disposed so as to be inclined with respect to the vertical direction. The ball stopper rubber has an air pressure-pressing portion formed inside thereof. Therefore, when a game ball collides with the reflective surface portion, the reflective surface portion of the ball stopper rubber bends. Since the I reflecting surface portion has a free, simply compared with the case of deformation, Tamatome rubber and reflects more energy dissipation game balls. Further, a disc-shaped ball stopper rubber is disclosed as a shape other than the rectangular shape. This disk-shaped ball stop rubber forms an air compression portion by forming a plurality of through holes (see, for example, Patent Document 1).

JP-A-8-243219

  The conventional ball stopper rubber is formed in a rectangular shape or a disk shape. The rectangular ball stop rubber has a large arrangement area for arrangement. In addition, the disc-shaped ball stopper rubber is reflected when the game ball hits the circumferential surface portion, and the reflection direction varies depending on the position where the circumferential portion hits. This makes it difficult for the player to predict the trajectory of the game ball, and it is necessary to repeat fine adjustment of the launch lever in order to hit the game ball at the target position. As a ball stopper rubber for solving such a problem, a teardrop-shaped ball stopper rubber is exemplified. However, with regard to a suitable shape for forming the air repressing portion, Patent Document 1 does not describe any shape other than the rectangular shape and the disk shape, and the game ball is further reduced in the teardrop-shaped ball stopper rubber. No information is given about the configuration.

  An object of the present invention is to provide a pachinko gaming machine in which a game ball is further reduced in a teardrop-shaped ball stopper.

The present invention is a pachinko gaming machine in which a rubber ball stop member is provided in which a gaming ball having a gaming area in which a gaming ball rolls is provided with a rubber ball stopping member that collides with the gaming ball that has been launched into the gaming area. The ball stopper member is formed in a teardrop shape in which the outer shape of the end surface in the thickness direction of the ball stopper member is a combination of an arc and a V shape, and the V shape extends in the thickness direction. in one of the two sides extending toward said arc from the top line, the pachinko gaming machine is intended to collide game balls on the side surface of the hand,
The ball stopper member is
A fixing hole for inserting a shaft-like fixing member for fixing the ball stopper member to the game board in the thickness direction;
A positioning hole for fitting a positioning member for determining a position around the rotation axis with the fixing member as a rotation axis in the thickness direction;
Than said fixing hole and the positioning holes possess a damping opening portion formed in the Ri side MenYadoriki of the hand,
The game board is provided with an arc-shaped outer rail for guiding the launched game ball to the game area,
The ball stopper is for causing a game ball to fly along the inner peripheral surface of the outer rail to collide, and is arranged so that the V-shaped top line is located in the vicinity of the inner peripheral surface of the outer rail. Has been established,
In a state where the game ball is in contact with both the inner peripheral surface and the one side surface of the outer rail, the game ball is in a contact plane between the game ball in the corresponding contact state and the inner peripheral surface of the outer rail. A virtual plane that is parallel and includes a contact point between the game ball in the contact state and the one side surface is defined as a first virtual plane,
The buffer hole is arranged so that the first imaginary plane passes through the space formed by the buffer hole,
The central axis of the buffer hole portion is parallel to the central axis of the fixed hole portion, and is included in a second virtual plane including a V-shaped top line and the central axis of the fixed hole portion,
The central axis of the buffer hole is included in the first virtual plane,
The central axis of the damping opening portion is a pachinko machine, wherein Rukoto from two side surfaces extending from the top line of the V-shape are formed on the same distance.

Further, in the present invention, the ball stopper member is fixed to the game board via a cover body on which the fixing member and the positioning member are formed.
The buffer hole portion is a through-hole portion penetrating in the thickness direction of the ball stopper member,
An opening on the player side of the buffer hole is covered with the cover body.

According to the present invention, since the damping opening portion is formed on the Ri side MenYadoriki the hand than the fixed hole and the positioning hole, even if the game ball collides with the side surface of the hand, damping opening portion Disperses the impact force received by one side surface including one side surface. Thereby, the rebound resilience of one side surface portion is reduced, that is, the repulsive force applied to the game ball from one side surface portion is reduced. In this way, the rate at which the game ball is de-energized is greater than that of the conventional ball stopper, and the impact of the game ball bounced back by the ball stopper on the game nail in the game area is the conventional ball stopper. It is smaller and damage to the game nail is suppressed. Also, since the impact force received by one side surface portion of the buffer hole portion is dispersed, even if the game ball repeatedly collides with the ball stopper member, the fixing member inserted through the fixing hole portion and the positioning member fitted into the positioning hole portion It is possible to suppress the load from concentrating on and to prevent the fixing member and the positioning member from being damaged by fatigue.

Moreover , it arrange | positions so that the V-shaped top line of a ball stop member may be located in the inner peripheral surface part vicinity of an outer rail. Further damping opening portion, in a state where a game ball is in contact with both aspects of the inner peripheral surface and hand of the outer rail, the game balls in contact with the inner circumferential surface of the game ball and the outer rail of the abutment it is parallel to the tangent plane, and the first virtual plane is a virtual plane including the contact point between the game ball with the hand side surface of the contact state is passed through the space formed by the buffer hole It is formed as follows. When the kinetic energy of the game ball is greater than or equal to a predetermined level, the game ball flies in contact with the outer rail and collides with the ball stopper. By forming the buffer hole so that the first virtual plane passes through the space formed by the buffer hole, when the game ball having a strong momentum hits the ball stopper member, the game ball is sent. The buffer hole can be interposed in the direction to be. Since the buffer hole portion is interposed in the flying direction in this way, the ball stopper member is easily deformed, and the impact force is more efficiently dispersed. The fatigue destruction of the game nail is caused by the fact that a game ball having a high momentum, that is, a large kinetic energy, is reflected without being reduced and repeatedly hits the game nail. By forming the buffer hole so that the first virtual plane passes through the hole formed by the buffer hole, it is possible to more efficiently depress such a strong game ball, and more game nails Can further suppress fatigue fracture. The damping opening portion and is formed in the Ri hand side MenYadoriki than the positioning hole and the fixing hole part, be momentum strong game balls collide with the reflecting portion receives the one side surface by the collision Before the impact force reaches the positioning hole portion and the fixing hole portion, it is dispersed by the buffer hole portion. As a result, even if the impact force repeatedly acts on one side surface portion, it is possible to suppress the occurrence of fatigue failure in the positioning member and the fixing member.

  According to the present invention, the impact hole portion is a through hole portion penetrating in the thickness direction, and the opening portion on the player side of the buffer hole portion is covered with the cover body. This makes it possible to fix the ball stopper member to the game board without deteriorating the beauty.

The cover body 13 is formed with a columnar fixing member 26 for fixing the ball stopper rubber 11 and a columnar positioning member 27 for positioning the ball stopper rubber.

  The ball stopper rubber 11 which is a ball stopper member has a teardrop shape formed by combining a circular arc and a V-shaped cross section as viewed by cutting along a virtual plane perpendicular to the thickness direction. In other words, the outer shape of the end surface in the thickness direction of the ball stopper rubber 11 is formed in a teardrop shape. The ball stopper rubber 11 has a ball stopper rubber body 28 made of synthetic rubber. The ball stopper rubber body 28 is formed in a teardrop shape, for example, a vibration damping rubber having a rubber hardness of 35 (JIS K6253). However, it is not limited to those having such rubber hardness, and any vibration-damping rubber made of natural rubber or synthetic rubber may be used.

A fixing hole portion 30 through which the fixing member 26 is inserted is formed on one surface portion in the thickness direction of the ball stopper rubber body 28, and a positioning hole portion 31 into which the positioning member 27 is fitted is formed in the vicinity of the fixing hole portion 30. Is formed. In the present embodiment, the fixing hole 30 is formed around the central axis L1 of the arc, and the positioning hole 31 is formed near the V-shaped top line 28a of the ball stopper rubber body 28 from the fixing hole 30. . The fixing hole 30 is formed so as to penetrate in the thickness direction, and the positioning hole 31 is formed in a concave shape that is recessed in the thickness direction.

A buffer hole 29 is further formed in the ball stop rubber body 28. The buffer hole 29 has a diameter of 3 mm, is formed around the central axis L2 parallel to the central axis L1, and is a hole that penetrates in the direction of the central axis L2. The buffer hole 29 is formed so that a virtual plane P1 which is a first virtual plane passes through a through hole formed in the inside thereof. As shown in FIGS. 2 and 4, the virtual plane P <b> 1 is an inner peripheral surface of the game ball 34 and the outer rail 23 that are in contact with each other when the game ball 34 is in contact with both the outer rail 23 and the reflecting portion 33. This is a virtual plane that is parallel to the contact plane of the game ball 34 at the contact point 34a and passes through the contact point 34b between the game ball 34 and the reflection portion 33 in the contact state. The reflecting portion 33 is one side portion of two side portions extending linearly from the V-shaped top line 28a toward the arc. Further, the V-shaped top line 28a is a line connecting the tops of the V-shaped portions in a plurality of cross sections obtained by cutting the ball retaining rubber main body 28 along a cross section perpendicular to the thickness direction thereof. It is a line extending in the thickness direction. In the present embodiment, the central axis L2 is included in a virtual plane which is a second virtual plane including the V-shaped top line 28a and the central axis L1, and the buffer hole 29 is located on the virtual plane P1 in the central axis L2. Is formed to be included. More specifically, the V-shaped part is formed in an isosceles triangle, and the central axis L2 is formed at a position at an equal distance T1 from two side surfaces extending from the V-shaped top line 28a. The buffer hole 29 formed in this way is disposed closer to the reflecting portion 33 than the positioning hole 31. More specifically, the distance T2 from the reflecting surface 32 of the positioning hole 31 is formed to be larger than the distance T1. The reflecting surface 32 is a side surface as one side surface formed by the reflecting portion 33 out of two side surfaces extending linearly from the V-shaped top line 28a toward the arc.

The ball stopper rubber 11 is fixed to the game board by inserting the fixing member 26 into the fixing hole 30, and is rotated about the fixing member 26 as the rotation axis by fitting the positioning member 27 into the positioning hole 31. Positioning around the axis. In this manner, the ball stopper rubber 11 is positioned and fixed in the vicinity of the upper end 13b of the one side surface portion 13a of the cover body 13. The fit includes a loose fit and a close fit. Accordingly, the ball stopper rubber 11 is fixed to the game board 15 and provided in the vicinity of the inner peripheral portion of the outer rail 23. The vicinity of the inner peripheral surface portion of the outer rail 23 includes not only the vicinity of the inner peripheral surface portion of the outer rail 23 but also the contact of the inner peripheral surface portion of the outer rail 23. In the present embodiment, the ball stopper rubber 11 is provided so as to contact the end of the outer rail 23. The ball stopper rubber 11 provided in this manner is fixed to the game board 15 so that the reflective surface 32 faces the game area 22 and the reflective surface 32 is positioned in the vertical direction on the cover body 13. Fixed. Furthermore spherical stopper rubber 11, the reflection portion 33 is exposed from the cover body 13, and as the open mouth 29a of the damping opening portion 29 is not exposed from the cover body 13 to the outside, it is arranged in the cover body 13 .

  Further, the game area 22 is provided with a liquid crystal display 35, a start winning device 36, and a special variable winning device 37. In the present embodiment, a liquid crystal display 35 is disposed at the center of the game area 22, and a start winning device 36 is disposed below the liquid crystal display 35. Further, a special variable winning device 37 is disposed on the right side from the start winning device 36 toward the paper surface of FIG. Furthermore, a large number of game nails 38 and windmills 39 are provided in the game area 22.

  When the game ball 34 enters the winning opening of the start winning device 36, that is, wins, a plurality of symbols are displayed on the display screen of the liquid crystal display 35, and the plurality of symbols are displayed for a predetermined time. When a plurality of symbols are stopped and displayed in a specific stop display mode, the door 40 that has blocked the winning opening of the special variable winning device 37 until then is opened and closed according to predetermined operating conditions. When the door 40 is opened, the winning opening of the special variable winning device 37 is opened, and the game ball 34 can be won into the special variable winning device 37. As a result, the player can perform a special game that launches the game ball 34 toward the special variable winning device 37 and wins the game ball 34 to the special variable winning device 37. In the case of a special game, in order to launch the game ball 34 toward the special variable prize-winning device 37, the player makes a strong hit that causes the launch lever 21 to rotate greatly, so-called right hit. The game ball 34 thus fired falls in the area on the right side of the game area 22 and wins the special variable winning device 37 in a state where the door 40 of the special variable winning device 37 is open. It is possible to obtain a profit (prize ball) that cannot be obtained in a normal game.

  Thus, in the case of a privilege game, when the player makes a right turn, the launch lever 21 is pivoted greatly, and when the angular displacement reaches a predetermined size, the game ball 34 launched by the launch device is While being guided by the outer rail 23, it is sent to the game area and collides with the reflecting portion 33 of the ball stopper rubber 11. Then, the game ball 34 colliding with the reflecting portion 33 deforms the reflecting portion 33. Thereafter, when returning, the reflecting unit 33 gives a repulsive force to the game ball 34 and rebounds the game ball 34. At this time, the impact force received by the reflecting portion 33 from the game ball 34 is dispersed by the buffer hole portion 29. By dispersing the impact force in this manner, the rebound resilience of the reflecting portion 33 is reduced, and the repelling force imparted to the game ball 34 by the reflecting portion 33 is reduced. As a result, the game ball 34 is de-energized. The game balls 34 that fly while in contact with the outer rail 23 have a strong momentum. Even if such a strong game ball 34 collides with the reflecting portion 33, the buffer hole 29 is on the virtual plane P1, that is, the buffer hole 29 is formed in the direction in which the game ball 34 is sent. Therefore, the impact force at the time of collision can be more efficiently distributed. More specifically, an extension line extending in a direction in which the game ball 34 jumps from a position (contact point 34b) where the game ball 34 flying while contacting the outer rail 23 collides with the reflecting portion 33 is an imaginary plane. Included in P1. In other words, the buffer hole 29 is formed in the direction in which the game ball 34 is sent from the contact 34b. Accordingly, the buffer hole 29 is more easily deformed in the direction in which the impact force acts, and the impact force can be further dispersed. As a result, the insufficient de-energization of the game ball 34 that may cause the fatigue failure of the game nail 38 is resolved, and the ball stopper rubber 11 can sufficiently de-energize and reflect the game ball 34. The game ball 34 reflected in this manner collides with a game nail 38 disposed in the vicinity of the ball stopper rubber 11 and is dropped downward, and when the door 40 is open as described above, it is specially variable. The winning device 37 can be awarded.

  The effects produced by the ball stopper rubber 11 having such a configuration will be described below. According to the ball stopper rubber 11 of the present embodiment, the buffer hole 29 is formed closer to the reflecting portion 33 than the fixed hole 30 and the positioning hole 31, so that the game ball 34 collides with the reflecting portion 33. Even so, the shocking force received by the reflection hole 33 is dispersed. As a result, the rebound resilience of the reflecting portion 33 is reduced, that is, the repulsive force applied from the reflecting portion 33 to the game ball 34 is reduced. Thus, the rate at which the game ball 34 is de-energized is larger than that of the conventional ball stopper rubber, and the impact of the game ball 34 rebounded by the ball stopper rubber 11 on the game nail 38 in the game area 22 It is smaller than the ball stopper rubber of the technology, and damage to the game nail 38 is suppressed. In addition, since the shock-absorbing portion 29 disperses the impact force received by the reflecting portion 33, even if the game ball 34 repeatedly collides with the ball stopper rubber 11, the fixing member 26 and the positioning hole portion 31 inserted through the fixing hole 30. It can suppress that a load acts on the positioning member 27 fitted, and it can suppress that the fixing member 26 and the positioning hole part 31 carry out a fatigue failure.

  According to the ball stopper rubber 11 of the present embodiment, the V-shaped top line 28 a is disposed in the vicinity of the inner peripheral surface portion of the outer rail 23. Further, the buffer hole portion 29 has a contact 34a between the game ball 34 in contact with the inner peripheral surface of the outer rail 23 and the game ball 34 in contact with both the inner peripheral surface of the outer rail 23 and the reflecting portion 33. A virtual plane P1 that is parallel to the tangential plane of the contacted game ball 34 and includes a contact point 34b between the contacted game ball 34 and the reflecting portion 33 is formed by the buffer hole 29. It is formed so as to pass through the space. When the kinetic energy of the game ball 34 is not less than a predetermined level, the game ball 34 is thrown in contact with the outer rail 23 and collides with the ball stopper rubber 11. By forming the buffer hole 29 so that the virtual plane P1 passes through the space formed by the buffer hole 29, when the game ball 34 having a strong momentum hits the ball stopper rubber 11, the game ball 34 The buffer hole 29 is interposed in the direction in which the air flies. Since the buffer hole 29 is interposed in the flying direction in this way, the ball stopper rubber 11 is easily deformed, and the impact force is more efficiently dispersed. The fatigue failure of the game nail 38 is caused by the fact that the game ball 34 having a strong momentum, that is, a large kinetic energy, is reflected without being reduced and repeatedly hits the game nail 38. By forming the virtual plane P1 in the buffer hole 29 so as to pass through the space formed by the buffer hole 29, such a strong game ball 34 can be more efficiently reduced, The fatigue failure of the game nail 38 can be further suppressed. Further, since the buffer hole 29 is formed closer to the reflecting portion 33 than the positioning hole 31 and the fixing hole 30, even if a strong game ball 34 collides with the reflecting portion 33, it is received by the collision. Before the impact force reaches the positioning hole 31 and the fixing hole 30, it is dispersed by the buffer hole 29. As a result, even if the impact force repeatedly acts on the reflecting portion 33, it is possible to suppress the occurrence of fatigue failure in the fixing member 26 and the positioning member 27.

  According to the ball stopper rubber 11 of the present embodiment, the impact hole portion 29 is a through-hole portion that penetrates in the thickness direction, and the player-side opening 29 a of the buffer hole portion 29 is covered with the cover body 13. Is done. This makes it possible to fix the ball stopper rubber 11 to the game board 15 without deteriorating the beauty.

  According to the ball stopper rubber 11 of the present embodiment, by forming the buffer hole 29, the gaming ball 34 can be efficiently de-energized while maintaining the rigidity of the ball stopper rubber 11 as a whole.

  FIG. 5 is a front view showing a ball stopper 11A of the second embodiment. The ball stopper 11A according to the second embodiment is similar in configuration to the ball stopper rubber 11 according to the first embodiment. For the ball stopper rubber 11A, only the configuration different from that of the ball stopper rubber 11 of the first embodiment will be described, and the same components will be denoted by the same reference numerals and description thereof will be omitted. The ball stopper 11A has a ball stopper rubber main body 28, and a buffer hole 29A, a fixing hole 30 and a positioning hole 31 are formed in the ball stopper rubber main body 28. The buffer hole 29 </ b> A is formed in parallel to the reflection surface 32. The buffer hole 29A is formed such that one end 29b in the longitudinal direction intersects the virtual plane P1, and the other end 29c in the longitudinal direction is formed near the end of the arc. As a result, a reflective layer 33A is formed between the buffer hole 29A and the reflective surface 32. When the game ball 34 collides with the reflective layer 33A, the reflective layer 33A is deformed so as to bend toward the buffer hole 29 as shown by a two-dot chain line in FIG. As the reflection layer 33A is deformed in this way, the impact force received from the game ball 34 is dispersed, and the game ball 34 is de-energized and reflected.

  The ball stopper rubber 11A according to the second embodiment has the same effects as the ball stopper rubber 11 according to the first embodiment. Furthermore, the buffer hole portion 29 </ b> A can depress in a wider range than the buffer hole portion 29 at a position away from the reflecting surface 32. Even when the buffer hole portion 29A is formed in this way, the ball stopper rubber 11A is in the shape of a teardrop, so that the thickness of the entire ball stopper rubber 11A in the direction perpendicular to the reflecting surface 32 is not reduced, and the ball stopper The game ball 34 can be de-energized while maintaining the rigidity of the rubber 11A.

  In the present embodiment, the buffer hole portion 29A is formed such that its longitudinal end 29b intersects the virtual plane P1, but is not necessarily limited to such a position. For example, one end 29b in the longitudinal direction of the buffer hole 29A may be formed to extend from the virtual plane P1 toward the V-shaped top line 28a. The other end 29c in the longitudinal direction of the buffer hole 29A may be formed to extend further to the arc side than the end of the arc. As a result, when the game ball 34 is in contact with the outer rail 23 and collides with the ball stopper rubber 11, the reflecting portion 33 can be further deformed, and the game ball 34 can be further de-energized.
