Description

  The present invention relates to a ball game machine such as a pachinko machine.

  A ball game machine represented by a pachinko machine has a game area in which winning means are arranged on the front surface of the game board, and a game ball launched into the game area by the launching means wins the winning means. In such a case, the player can receive a corresponding profit by paying out a prize ball corresponding to the winning or the like.

  The launching means mounted on this type of ball game machine uses a striking rod driven at a speed corresponding to the operation amount of the launching handle, and the game balls supplied one by one on the launching rail are supplied to the launching rail. The mainstream is configured to strike along.

  By the way, if the launching operation of the launching means is unstable, even if the operation amount of the launching handle is constant, variations in the flying of the game ball occur, and the player cannot control the launching as intended. Various measures have been studied to stabilize the launching operation due to. Under such circumstances, a tip trajectory holding member that slidably holds the vicinity of the tip of the hitting ball is provided on the launch rail so that the tip of the hitting ball always hits a certain position of the game ball. Japanese Patent Application Laid-Open No. H10-228867 describes a launching device that attempts to stabilize the launching operation.

In the launching device described in Patent Document 1, the tip raceway holding member provided with the bearing hole is fixed to the rear end side of the launch rail, and the tip side of the solenoid plunger (striking rod) is connected to the tip raceway holding member. It is said that the relative positional relationship between the tip and the game ball at the moment of striking can always be kept constant by penetrating through the bearing hole.
Japanese Patent Laid-Open No. 11-104299

  In the launching device described in Patent Document 1, since the striking rod is slidably held by the bearing hole of the tip raceway holding member, the load due to friction or the like is likely to increase, and the load also changes over time. This could cause a new cause of unstable launching.

  Also, the striking position of the striking trajectory holding member by the tip trajectory holding member moves from the tip side to the base side during the firing operation and is held at the position farthest from the tip side at the moment of hitting. There is also a problem that the relative positional relationship between the tip and the game ball at the moment of hitting changes greatly even if the holding position changes slightly.

  The present invention has been made in view of the above circumstances, and can keep the relative positional relationship between the tip and the game ball constant at the moment of hitting while keeping the load acting on the hitting pole to a minimum. An object is to provide a possible ball game machine.

  In the present invention, the launching means 8 for launching the game balls supplied one by one on the launch rail 52 along the launch rail 52 with the strike rod 53 toward the game area 6a on the game board 6 side is provided. In the ball game machine, wherein the hitting bar 53 is configured to be reciprocally driven substantially parallel to the shooting rail 52 by the shooting driving means 54, 91, the tip side of the hitting bar 53 is a substantially straight track. A tip end track holding means 55 is provided for holding the tip end track holding means 55. The tip end track holding means 55 is rotatably connected to the tip side of the striking rod 53 by the side link shafts 61a and 71a. And both ends of the center links 61, 71 are rotatably connected by first and second connecting shafts 61b, 61c, 71b, 71c, respectively, and are rotatable to the gaming machine body 1 on both sides of the striking rod 53. axis Link mechanisms 64, 70 constituted by first and second side links 62, 63, 72, 73, which are arranged on a predetermined virtual plane parallel to the striking rod 53. When the first and second side links 62, 63, 72, 73 are parallel to each other, the first and second side links 62, 63, 72, 73 are substantially orthogonal to the firing rail 52. The link lengths of the second and first side links 63, 62, 73, 72 between the first and second connection shafts 61b, 61c, 71b, 71c It is provided at a position internally divided by the ratio.

  According to the present invention, the tip side of the hitting rod 53 is a substantially straight line parallel to the firing rail 52, and the holding position of the hitting rod 53 by the tip trajectory holding means 55, that is, the hook-side connecting shaft 61a on the hitting rod 53. The position of is always the same from when the hitting rod 53 is in the retracted state to the moment of hitting. Further, since the tip trajectory holding means 55 uses the link mechanism 64, a large load is not applied to the hitting rod 53 due to friction or the like. Therefore, it is possible to always keep the relative positional relationship between the tip of the hitting ball and the game ball at the moment of hitting while minimizing the load acting on the hitting ball 53.

The link mechanism 64 is provided such that each of the links 61 to 63 is disposed on a virtual plane (hereinafter referred to as a vertical virtual plane) parallel to the game board 6 and is operable on the vertical virtual plane.

  The center link 61 is disposed, for example, on the rear side of the striking rod 53 so as to substantially follow the striking rod 53, and by a front-side connecting shaft 61a in the front-rear direction (direction perpendicular to the vertical virtual plane) disposed between both ends thereof. It is rotatably connected to the vicinity of the tip 53a of the hitting rod 53.

  The first side link 62 is rotatably connected to the end of the center link 61 on the side of the tip 53a by a first connecting shaft 61b in the front-rear direction (a direction perpendicular to the vertical virtual plane). It is arranged toward the upper side, and is pivotally supported, for example, rotatably on the mounting plate 56 by a support shaft 62a in the front-rear direction (direction perpendicular to the vertical virtual plane) on the end side opposite to the center link 61 side. ing.

  Further, as shown in FIG. 8, when the link mechanism 64 is in a state just in the middle of a single movable range when it is separated from the striking rod 53 (hereinafter referred to as an intermediate posture), the first and second side links 62. , 63 are arranged parallel to each other and substantially orthogonal to the firing rail 52. Further, the heel side connection shaft 61a is provided at a position where the space between the first and second connection shafts 61b and 61c is internally divided by the ratio of the link lengths of the second and first side links 63 and 62. That is, the distance between the heel-side connecting shaft 61a and the first connecting shaft 61b is d1, the distance between the heel-side connecting shaft 61a and the second connecting shaft 61c is d2, the link length of the first side link 62 is L1, and the second side When the link length of the link 63 is L2, the position of the heel side connecting shaft 61a on the center link 61 is set so that the relationship d1: d2 = L2: L1 is established.

  Thereby, as shown in FIG. 8, the trajectory on the vertical virtual plane of the heel side connection shaft 61a becomes a straight line substantially parallel to the firing rail 52, and the tip side of the striking rod 53 connected to the heel side connection shaft 61a is Move on the orbit. The trajectory of the heel-side connecting shaft 61a is not strictly a straight line, but the fluctuation is almost negligible, and even if not strictly a straight line, the trajectory is always constant. The relative positional relationship between the tip and the game ball at the moment is always constant. Further, the holding position of the hitting rod 53 by the tip trajectory holding means 55, that is, the position of the hook-side connecting shaft 61a on the hitting rod 53 is always the same from when the hitting rod 53 is in the retracted state to the moment of hitting. The tip portion can be accurately held at a predetermined position. Further, since the tip trajectory holding means 55 uses the link mechanism 64, it is unlikely that a large load is applied to the hitting rod 53 due to friction or the like.

  In the present embodiment, the link lengths L1 and L2 of the first side link 62 and the second side link 63 are equal, so that the heel side connection shaft 61a is provided at the exact center between the first connection shaft 61b and the second connection shaft 61c. However, for example, when the first side link 62 and the second side link 63 cannot be equal in length due to space, the position of the heel side connecting shaft 61a on the center link 61 is expressed by the above formula. It may be adjusted based on the above. FIG. 9 shows an example in which L1> L2, and FIG. 10 shows an example in which L1 <L2.

  In the present embodiment, when the link mechanism 64 is in the intermediate position, the center link 61 is arranged so as to be orthogonal to the first and second side links 62 and 63, that is, in parallel with the striking rod 53. The crossing angle between the center link 61 and the first and second side links 62 and 63 when the mechanism 64 is in the intermediate posture may be smaller or larger than 90 degrees. 9 shows an example in which the intersection angle between the center link 61 and the side links 62 and 63 is smaller than 90 degrees, and FIG. 10 shows an example in which the intersection angle is similarly larger than 90 degrees.

  Further, it is arbitrary at which position in the movable range of the hitting rod 53 the link mechanism 64 is connected to the hitting rod 53 so as to be in an intermediate posture. In this embodiment, the link mechanism 64 is in the intermediate position when the striking rod 53 is in the middle of the movable range from the retracted state to the firing state. For example, the striking rod 53 is in the retracted state or the firing state. In some cases, the link mechanism 64 may be in an intermediate posture. Further, the link mechanism 64 may not be in the intermediate position within the movable range of the striking rod 53.

  As described above, the pachinko machine according to the present embodiment includes the tip trajectory holding means 55 that holds the tip side of the striking hammer 53 on a substantially straight trajectory. A center link 61 is rotatably connected to the tip side of the striking rod 53 by a connecting shaft 61a, and is rotatably connected to both ends of the center link 61 by first and second connecting shafts 61b and 61c, respectively. A link mechanism 64 including first and second side links 62 and 63 rotatably supported on the gaming machine main body 1 on both sides of the hitting bar 53 is provided. The link mechanism 64 is parallel to the hitting bar 53. The first and second side links 62 and 63 are arranged so as to be substantially orthogonal to the firing rail 52 when the first and second side links 62 and 63 are parallel to each other.槌 side connection 61a is provided at a position that internally divides the first and second connecting shafts 61b and 61c by the ratio of the link lengths of the second and first side links 63 and 62, so that the tip side of the striking rod 53 is fired. The holding position of the hitting rod 53 by the tip trajectory holding means 55, that is, the position of the hook-side connecting shaft 61a on the hitting rod 53 is determined from the time when the hitting rod 53 is in the retracted state. Always the same up to the moment. Further, since the tip trajectory holding means 55 uses the link mechanism 64, a large load is not applied to the hitting rod 53 due to friction or the like. Therefore, it is possible to always keep the relative positional relationship between the tip of the hitting ball and the game ball at the moment of hitting while minimizing the load acting on the hitting ball 53.

  In addition, the tip trajectory holding means 55 includes a link mechanism 64 that is operatively arranged on a vertical virtual plane substantially parallel to the game board 6, so that the tip and bottom of the tip and the game ball at the moment of hitting are particularly high. It becomes possible to always keep the relative positional relationship in the direction constant.

  11 and 12 exemplify the second embodiment of the present invention, and the tip trajectory holding means 55 is constituted by two sets of link mechanisms 64 and 70 that are operatively arranged on a virtual plane orthogonal to each other. An example is shown.

  Of the two sets of link mechanisms 64 and 70 of the present embodiment, one link mechanism 64 has the same configuration as that of the first embodiment. The other link mechanism 70 is arranged on a virtual plane (hereinafter referred to as a horizontal virtual plane) that is parallel to the striking rod 53 and orthogonal to the vertical virtual plane on the link mechanism 64 side, and can operate on the horizontal virtual plane. The basic configuration is the same as that of the link mechanism 64.

  That is, the link mechanism 70 includes a center link 71 connected to the striking rod 53, and first and second side links 72 that connect both ends of the center link 71 and, for example, the mounting plate 56 on the gaming machine body 1 side. 73. Each link 71-73 is arrange | positioned on the horizontal virtual plane, and it is provided so that it can operate | move on the vertical virtual plane.

  The center link 71 is disposed, for example, on the upper side of the hitting bar 53 so as to substantially follow the hitting bar 53, and by a hook-side connecting shaft 71a in a substantially vertical direction (a direction perpendicular to the horizontal virtual plane) arranged between both ends thereof. It is rotatably connected to the vicinity of the tip 53a of the hitting rod 53.

  The first side link 72 is rotatably connected to the end 53a side end of the center link 71 by a first connecting shaft 71b in a substantially vertical direction (a direction perpendicular to the horizontal virtual plane). For example, the bracket 81 that is disposed on the rear side and is integrated with, for example, the mounting plate 56 by the support shaft 72a in the substantially vertical direction (direction perpendicular to the horizontal virtual plane) on the end side opposite to the center link 61 side. It is pivotally supported with respect to the shaft. The bracket 81 is provided on the back surface side of the mounting plate 56, for example, and the first side link 72 is attached to the bracket 81 through the opening 56a provided in the mounting plate 56 backward.

  The second side link 73 is rotatably connected to the end of the center link 71 opposite to the tip 53a by a second connecting shaft 71c in a substantially vertical direction (a direction perpendicular to the horizontal virtual plane). For example, the mounting plate 56 is integrated with a support shaft 73a in a substantially vertical direction (a direction perpendicular to the horizontal virtual plane) on the end side opposite to the center link 71 side. The bracket 82 is rotatably supported with respect to the bracket 82.

  Further, when the link mechanism 70 is in an intermediate state (intermediate posture) of a single movable range when separated from the striking rod 53, the first and second side links 72 and 73 are parallel to each other and the firing rail 52 It is arrange | positioned so that it may orthogonally cross. Further, the heel side connecting shaft 71a is provided at a position where the distance between the first and second connecting shafts 71b and 71c is internally divided by the ratio of the link lengths of the second and first side links 73 and 72. That is, the distance between the heel-side connecting shaft 71a and the first connecting shaft 71b is d1, the distance between the heel-side connecting shaft 71a and the second connecting shaft 71c is d2, the link length of the first side link 72 is L1, and the second side When the link length of the link 73 is L2, the position of the heel-side connecting shaft 71a on the center link 71 is set so that the relationship d1: d2 = L2: L1 is established.

  Thereby, the track on the horizontal virtual plane of the heel side connection shaft 71a becomes a substantially straight line parallel to the firing rail 52, and the tip side of the striking rod 53 connected to the heel side connection shaft 71a moves on the track. .

  In this manner, the tip end track holding means 55 provided with the link mechanism 64 and the link mechanism 70 allows the tip side of the hitting tip 53 to be in contact with the launch rail 52 without being shaken in any direction orthogonal to the axis. It can be held on one parallel or substantially straight track.

  FIG. 13 exemplifies a third embodiment of the present invention, in which the striking rod 53 is provided with a heel end track holding means 55 and a heel side provided with a link mechanism 64 similar to the heel tip track holding means 55 on the heel side. An example is shown in which the striking rod 53 is supported by the trajectory holding means 90 and the striking rod 53 is reciprocally driven by the firing driving means 91 separate from the striking rod 53.

  In this embodiment, the striking rod 53 is independent from the firing drive means 91, and the tip side and the base side thereof are parallel to the firing rail 52 by the tip trajectory holding means 55 and the base trajectory holding means 90, respectively. It is held on a substantially straight track.

  The tip trajectory holding means 55 includes a link mechanism 64 similar to that of the first embodiment. Also, the heel track holding means 90 is constituted by a link mechanism 64 that is substantially the same as the heel track holding means 55, and the center link 61 is connected to the heel side of the striking rod 53 by the heel side connecting shaft 61a. Has been.

  The firing drive means 91 is composed of, for example, a rotary solenoid, and is detachably fixed to, for example, the back side of the mounting plate 56 with the driving shaft 91a protruding to the front side of the mounting plate 56, and fixed to the driving shaft 91a. The tip end side of the driven lever 91b is connected to a connecting bracket 92 on the striking rod 53 side, for example. In addition, on the front side of the mounting plate 56, restricting members 93a and 93b for restricting the movable range of the striking rod 53 are arranged. For example, the regulating member 93a abuts against the base end side of the striking rod 53 to regulate the striking rod 53 in the retracted state, and the regulating member 93b abuts against a predetermined position on the driving lever 91b side of the firing driving means 91, for example. 53 is controlled in a firing state.

  As described above, the striking rod 53 is supported by the heel track holding means 55 and the heel track holding means 90 provided on the heel side with the link mechanism 64 similar to the heel track holding means 55. Even if the striking rod 53 is reciprocally driven by the firing driving means 91 separate from the striking rod 53, as in the first embodiment, the striking force acting on the striking rod 53 is minimized while striking. It is possible to always keep the relative positional relationship between the tip and the game ball at the moment.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to this embodiment, A various change is possible within the range which does not deviate from the meaning of this invention. For example, in the first embodiment, the tip trajectory holding means 55 is provided with only the link mechanism 64 disposed on the vertical virtual plane substantially parallel to the game board 6. Further, a tip trajectory holding means 55 having only the link mechanism 64 arranged on the horizontal virtual plane plane orthogonal to the vertical virtual plane on the link mechanism 64 side may be provided.

  Further, as in the first and third embodiments, when the heel track holding means 55, the heel track holding means 90, etc. are provided with only one set of link mechanisms, the striking rod 53 is orthogonal to the link mechanisms. A holding means for holding in the direction may be provided separately.

  In the case where a firing drive unit separate from the striking rod 53 is provided as in the third embodiment, the type of the firing drive unit is arbitrary, and any type such as a solenoid or a motor may be used.

  In addition, although pachinko machine was illustrated in embodiment, it cannot be overemphasized that it can implement similarly with other ball game machines, such as an arrangement ball machine and a sparrow ball game machine.
