Description

  The present invention relates to a pachinko machine that uses a game ball to play a game.

  In general, a pachinko machine supplies game balls in a saucer provided on the front surface of an apparatus main body one by one to an internal standby position, and the game balls held in the standby position are operated on a game board by operating a launching device. Fires towards the gaming area. The game board is provided with an outer rail that guides a game ball launched from the launching device to the upper side of the game area, and an inner rail that defines most of the peripheral wall of the game area. The space between the rails is a launch guide passage. In the vicinity of the launching device, a launching rail that is inclined upward toward the launching guide passage is provided, and the lower end of this launching rail is a standby position for holding a game ball, and the upper end of the launching rail and the launching guide passage Between the two, a rail missing portion is formed. The launching device has a hammer that is rotated using a rotary solenoid as a driving source, and the hammer is controlled to rotate according to the rotation angle of the launching handle provided at the lower front of the device body, so that the hammer is in the standby position. The game ball held by the player is hit.

  When the player rotates the launch handle to an arbitrary angle, the game ball supplied from the tray to the standby position on the launch rail is hit by the rotation of the hammer of the launcher. Jump over to the game basin from the launch guide passage. At that time, the game ball that could not reach the game area due to insufficient momentum at the time of launching travels backward through the launch guide passage and falls to the rail missing portion, and then fouls through the recovery passage continuous to the rail missing portion. Returned to the player as a ball. On the other hand, a sufficiently strong game ball passes through the launch guide passage and enters the game area, and when this game ball flows down the game area and enters the start winning prize opening, the general winning opening, etc. The game balls are paid out to the tray as prize balls. Here, a detection sensor such as a proximity switch is arranged inside the start winning opening and the general winning opening, and usually one detection sensor is arranged for one winning opening. The detection sensor outputs an on / off switching signal when the game ball passes, and the game ball that has entered the winning hole passes through the detection sensor, so that it depends on the type of the winning hole (start winning hole or general winning hole). A predetermined number of game balls are paid out to the tray as prize balls.

  Conventionally, as a go-to action in such a pachinko machine, a piano wire or the like is inserted into the game area from the gap of the device body, and a game ball is also entered in a specific area called a prize opening or V zone using this piano line or the like. Malfunctions such as illegally exploiting a prize ball or winning a jackpot game have become a problem by causing the detection sensor to malfunction as if it were. Therefore, two detection sensors are stacked in the vertical direction inside one winning opening, and only when the game balls are detected by the two detection sensors in order from the upper side to the lower side within a predetermined time, There has been proposed a pachinko machine equipped with a game ball passage recognition means for recognizing that a ball has been properly entered in a winning opening (see, for example, Patent Document 1). According to the pachinko machine equipped with such a game ball passage recognition means, a person who intends to act illegally inserts a piano wire or the like through a gap in the device body, and a prize is placed in the game area using the piano wire or the like. Even if it tries to stimulate the detection sensor in the mouth, it usually stimulates only one of the upper and lower two detection sensors, so it is not determined that the game ball has entered the winning opening normally, and the game ball is illegally It will not be paid out. Further, even if the two detection sensors in the winning opening can be stimulated using a piano wire or the like, the two detecting sensors are predetermined from the upper side to the lower side as if the game balls actually entered the winning opening. Since it is extremely difficult to output the detection signals in order within the time, fraudulent acts using a piano wire or the like can be prevented.

  By the way, the trick of gotoing to illegally exploit game balls has become more sophisticated every day, for example, illegal balls called thread balls with glued strings such as transparent fishing lines attached to game balls There is a problem with fraudulent acts called thread goto, which creates a state as if a game ball has entered by launching into the game area and manually guiding this ball with thread from the outside through the saucer to guide it to the prize opening and V zone It has become. This threading action is to put a game ball with a string-like body into a prize opening or a V zone and operate an internal detection sensor. By moving up and down in the vicinity of the entrance of the zone, it becomes possible for the ball with thread to behave in the same manner as a regular game ball. Therefore, in the conventional pachinko machine disclosed in Patent Document 1, such a thread is used. It was not possible to prevent goto action. In addition, in the conventional pachinko machine disclosed in Patent Document 1, since fraudulent acts are determined based on the detection signals of two detection sensors provided in one winning opening, it becomes a target of fraudulent acts. When the number of winning holes and V zones increases, there is a problem that the number of required detection sensors becomes very large and the cost increases.

  The present invention has been made in view of the actual situation of the prior art, and an object thereof is to provide a pachinko machine that can reliably prevent an illegal act using a threaded ball with a simple configuration.

  In order to achieve the above object, the present invention provides a game board having a game area in which a game ball flows down, a launching device having a hammer that is rotationally driven, and a game ball stored in a tray in a standby state of the launching device. An arm that rotates in conjunction with the hammer in a pachinko machine in which game balls held in the standby position are launched toward the game area by striking the hammer. And the game ball supplied from the rectifier passes through the arm member and is held at the standby position, and the arm member is moved to the standby position when the hammer rotates toward the standby position. Prior to, the game ball is rotated from the standby position in the launching direction of the game ball.

  In the pachinko machine configured as described above, the regular game balls stored in the tray are passed through the arm member while being rectified one by one by the rectifier and held at the standby position, and the hammer of the launcher is directed toward the standby position. By rotating in this manner, it is struck with a hammer and is launched toward the game area. At that time, the arm member rotates in the direction of launching the game ball from the standby position in advance of the hammer. However, since the arm member moves between the rectifier and the standby position, the arm member is rotating with the game ball on the standby position. There is no interference with the arm member. On the other hand, when a game ball (ball with a thread) to which a string-like body such as a fishing line is bonded is supplied from the tray to the standby position, the game ball passes through the arm member with the string-like body attached and is held at the standby position. However, when the arm member inserted through the string-like body rotates in the direction of launching the game ball from the standby position before the hammer, the string-like body attached to the game ball moves in the same direction together with the arm member. The ball with thread is released from the standby position in the launching direction before being hit with a hammer. As a result, even if the hammer rotates to the standby position, it will not contact the game ball, and it will not be possible to hit the ball with thread with the hammer and launch it into the game area. Can be prevented.

  In the above configuration, the arm member and the hammer may be connected via a relay member such as a gear. However, if the arm member and the hammer are connected on the same axis while maintaining a predetermined crossing angle, the existing launching device is connected. On the other hand, it is preferable that the arm member can be easily attached.

  In the above configuration, the shape of the arm member is not particularly limited as long as the string-like body attached to the game ball can be driven, but the arm member has a through hole through which the game ball passes between the rectifier and the standby position. When a large number of sawtooth grooves continuous in the circumferential direction are formed on the inner peripheral surface of the through hole, the string-like body attached to the game ball at the time of rotation of the arm member is inserted into an arbitrary sawtooth groove. Since it can be hooked, it can prevent more reliably that a ball | bowl with a thread | yarn is discharged to a game area.

  In the pachinko machine of the present invention, when a game ball (ball with a thread) to which a string-like body such as a fishing line is bonded is supplied from the receiving tray to the standby position, the game ball passes through the arm member with the string-like body on standby. When the arm member inserted through the string-like body rotates in the game ball launch direction from the standby position before the hammer, the string-like body attached to the game ball is the same as the arm member. In order to move in the direction, the ball with thread is released from the standby position in the launch direction before being hit with a hammer. As a result, even if the hammer rotates to the standby position, it will not contact the game ball, and it will not be possible to hit the ball with thread with the hammer and launch it into the game area. Can be prevented. In addition, since the firing of the threaded ball can be reliably prevented by simply adding an arm member without using a fraud determination means having a complicated circuit configuration, it is possible to prevent the structure from becoming complicated and the cost from being increased.

In FIG. 4, the variable display device 24 and the start winning ports 25 and 26 provided in the game area 8 are not shown. The outer rail 32 is arranged in an arc shape from the left position away from the out port 31 through the left end and upper end portion of the game board 7, and the upper end side of the outer rail 32 is continuous with the guide rail 9. The inner rail 33 is arranged in an arc shape from a position slightly on the left side of the outlet 31 to the upper end portion of the game board 7, and a ball return that prevents the game ball from returning from the game area 8 to the upper end portion of the firing guide passage 34. A prevention piece 35 is provided.

  As shown in FIG. 5, the launching device 23 includes a base plate 36 fixed to the installation portion 2 a of the main body frame 2, a rotary solenoid 37 attached to the back side of the base plate 36, and the front side of the base plate 36. And a hammer 38 and an arm member 39 which rotate (swing) integrally with a rotary solenoid 37 as a drive source, and a firing rail 40 provided on the front side of the base plate 36. The rotary solenoid 37 is a known electrical component in which the rotor is rotated by a predetermined angle by the attractive force generated when the coil is energized, and when the energization is stopped, the rotor is attracted by the permanent magnet and returned to the position before the energization. . The rotary solenoid 37 has a drive shaft 37a that protrudes from the rotor through the base plate 36 to the front side, and the base end side of the hammer 38 is fixed to the drive shaft 37a. The rotation angle of the hammer 38 is restricted by a pair of stoppers 41 and 42 protruding to the front side of the base plate 36, and a protrusion 38 a for hitting a game ball is formed on the tip side of the hammer 38. The arm member 39 is made of a synthetic resin molded product, and the base end side of the arm member 39 is also fixed to the drive shaft 37 a of the rotary solenoid 37. At that time, the arm member 39 and the hammer 38 are fastened together with the drive shaft 37a by using a nut 37b so as to form a predetermined crossing angle (for example, about 90 degrees), and both the members 38, 39 are maintained while maintaining this crossing angle. Are designed to rotate together. A through hole 39a that is somewhat larger than the diameter of the game ball is provided on the distal end side of the arm member 39, and a large number of sawtooth grooves 39b that are continuous in the circumferential direction are formed on the inner peripheral surface of the through hole 39a. ing.

  The firing rail 40 is inclined with an upward slope toward the firing guide passage 34, and the lowermost portion at the right end of the inclined surface is a standby position 40a. As shown in FIG. 4, a supply port 43a indicated by a two-dot chain line is opposed to a front position of the standby position 40a, and a through hole 39a of the arm member 39 is provided between the standby position 40a and the supply port 43a. Is arranged. The supply port 43 a is an outlet of the rectifier 43 that is connected to the upper tray 13 and protrudes toward the back side of the glass door 3 (see FIG. 2), and a large number of game balls stored in the upper tray 13 are lined up by the rectifier 43. Are supplied one by one from the supply port 43a through the through hole 39a of the arm member 39 to the standby position 40a. Further, a foul ball collection passage 44 is provided in the lower part of the space from the launch rail 40 to the launch guide passage 34, and protrudes from the lower tray 14 to the back side of the glass door 3 at the bottom of the foul ball collection passage 44. A ball collecting unit 14a (see FIG. 2) is located.

  In the pachinko machine P configured as described above, first, a case where a game is played using a regular game ball will be described with reference to FIG. The regular game balls B stored in the upper tray 13 are rectified one by one by the rectifier 43 and discharged from the supply port 43a, and then, as shown in FIG. It passes and is held at the standby position 40 a of the firing rail 40. At this time, the hammer 38 contacts the one stopper 41 and stops at the initial position, and the arm member 39 stops near the standby position 40a. When the player rotates the operation handle 16 in this state, a drive current corresponding to the amount of the rotation operation is applied to the coil of the rotary solenoid 37, and as shown in FIG. Rotates from the initial position toward the standby position 40a, and in conjunction with the hammer 38, the arm member 39 rotates from the vicinity of the standby position 40a in the game ball launch direction. Then, as shown in FIG. 6C, when the hammer 38 rotates to the operating position and comes into contact with the other stopper 42, the game ball B held at the standby position 40a is hit by the protrusion 38a of the hammer 38. As a result, the game ball B is launched in the direction of the launch guide passage 34 without interfering with the arm member 39. At that time, the game ball B that has not been able to reach the game area 8 through the launch guide passage 34 due to insufficient momentum at the time of launch, runs backward in the launch guide passage 34 and falls into the foul ball collection passage 44. The foul ball is returned to the lower tray 14 through the ball collecting portion 14a. On the other hand, the game ball B that is sufficiently vigorous at the time of launching jumps over the launch rail 40 and enters the launch guide passage 34, and then passes through the ball return prevention piece 35 disposed at the upper end of the launch guide passage 34. Enter 8 As described above, when the game ball B that has entered the game area 8 in this way enters the start winning opening 25, 26, a special symbol display lottery result is performed, and a predetermined number of game balls are used as prize balls. It is paid out to the player. Further, when the game ball B flowing down in the game area 8 enters the general winning opening 27, only a predetermined number of gaming balls are paid out, and it does not enter any of the starting winning openings 25, 26 or the general winning opening 27. The game ball B is discharged from the out port 31 to the back side of the game board 7.

  Next, a case where a person who intends to engage in fraud adheres and fixes a string 45 such as a fishing line to a game ball and plays a game using such a ball with a thread will be described with reference to FIG. When the game ball (threaded ball) B1 with the string-like body 45 is inserted into the upper tray 13, the game ball B1 is discharged from the supply port 43a of the rectifier 43 with the string-like body 45 attached, and then FIG. As shown in (a), since it passes through the through hole 39a of the arm member 39 and is supplied to the standby position 40a of the firing rail 40, the game ball B1 is in a state where the string-like body 45 is inserted through the through hole 39a. It is held at the standby position 40a. When the player rotates the operation handle 16 in this state, the hammer 38 rotates from the initial position toward the standby position 40a and interlocks with the hammer 38, as in the case where the regular game ball is used. Thus, the arm member 39 rotates in the direction of launching the game ball from the vicinity of the standby position 40a. At this time, the arm member 39 rotates in the launch direction with the string-like body 45 inserted through the through-hole 39a, so that the string-like body 45 has an inner peripheral surface of the through-hole 39a as shown in FIG. It moves in the same direction together with the arm member 39 while being caught in one of the serrated grooves 39b formed in the above, and is pulled by the string-like body 45 to move the game ball B1 from the standby position 40a in the launch direction. Therefore, as shown in FIG. 7C, even when the protrusion 38a of the hammer 38 reaches the standby position 40a, the game ball B1 does not exist at the standby position 40a, and the game ball B1 is hit with the hammer 38 and fired. It is impossible to fire in the direction of the guide passage 34.

  When the rotary solenoid 37 reverses and the hammer 38 returns to the initial position, the arm member 39 also returns to the vicinity of the standby position 40a in conjunction with the hammer 38, and the game ball (threaded ball) B1 returns to the standby position 40a again. However, when the hammer 38 subsequently rotates from the initial position toward the standby position 40a, the arm member 39 that rotates in conjunction with the hammer 38 repeats the same operation as described above. That is, as long as the threaded ball B1 is used, the threaded ball B1 cannot reach the game area 8. Therefore, the stringed body 45 is manually operated from the outside to start the threaded ball B1 with the start winning opening 25. , 26, the general winning opening 27, etc., and it is possible to reliably prevent an illegal act using the threaded ball B1.

  As described above, in the pachinko machine P according to this embodiment, the launching device 23 includes the arm member 39 that rotates in conjunction with the hammer 38, and a game ball (threaded ball with a string-like body 45) is attached. ) When B1 is supplied from the upper tray 13 to the standby position 40a, the game ball B1 passes through the through hole 39a of the arm member 39 with the string-like body 45 attached and is held at the standby position 40a. Therefore, when the hammer 38 rotates from the initial position toward the standby position 40a, the arm member 39 rotates in the launching direction from the standby position 40a in advance of the hammer 38 and is inserted through the through hole 39a. 45 moves in the same direction together with the arm member 39. As a result, the game ball B1 is pulled by the string-like body 45 and is released from the standby position 40a in the launch direction, so that the game ball B1 cannot be hit even if the hammer 38 rotates to the standby position 40a. Unauthorized acts using the attached ball B1 can be reliably prevented. In addition, an illegal act using the threaded ball B1 is not electrically determined based on an output signal of the detection sensor or the like, but the arm member 39 prevents the illegal act by blocking the firing of the threaded ball B1 itself. Therefore, it is possible to prevent the structure from becoming complicated and the cost from being increased.

  Further, in the pachinko machine P according to the present embodiment, the hammer 38 and the arm member 39 are connected on the drive shaft 37a of the rotary solenoid 37 while maintaining a predetermined crossing angle. It is only necessary to add the arm member 38 to the member, and the arm member 38 can be easily attached. However, it is possible to form the hammer 38 and the arm member 39 from the same material so as to be integrated, or to connect the hammer 38 and the arm member 39 via a relay member such as a gear. It suffices if the member 39 rotates synchronously with the rotary solenoid 37 as a drive source.

  Furthermore, in the pachinko machine P according to the present embodiment, the arm member 39 has a through hole 39a through which the game ball passes on the tip side, and a large number of saw teeth continuous in the circumferential direction on the inner peripheral surface of the through hole 39a. Since the groove 39b is formed, not only when the arm member 39 rotates in the launch direction from the standby position 40a, but also when the arm member 39 rotates in the direction to return to the standby position 40a, the through-hole 39a is inserted. The string-like body 45 can enter and be hooked into an arbitrary serrated groove 39b, and the game ball (ball with yarn) B1 can be reliably moved in the rotation direction of the arm member 39. However, the shape of the arm member 39 is not limited to this, and for example, it is possible to use a rod-shaped arm member 39 having no through hole 39a. In short, when the hammer 38 rotates toward the standby position 40a. It is sufficient that the arm member 39 that rotates in conjunction with it can come into contact with the string-like body 45.

  In the above embodiment example, the pachinko machine P provided with the start winning ports 25, 26, the attacker device 29, etc. in the game area 8 of the game board 7 has been described, but the present invention is called the V zone in the game area 8. The present invention can also be applied to a pachinko machine P provided with a specific area.
