Description

  The present invention relates to a gaming machine such as a pachinko machine, an arrangement ball machine, and a sparrow ball machine, and more particularly to a hitting guide rail disposed on the surface of the gaming board.

  Generally, in a pachinko machine, a metal strip is bent in a spiral shape, and a plurality of places are nailed to the game board surface, and a hitting guide rail is attached. The outer rail of the hitting guide rail is for smoothly guiding the game ball to the game area.

  However, there is also a proposal to make the guide rail as a synthetic resin because the work of nailing the metal strip is troublesome and lacks in decorativeness (Patent Document 1).

  In Patent Document 1, as shown in FIG. 14 (A), the outer rail unit, the intermediate rail unit, and the inner rail unit are integrally formed on the back side of the rail unit by connecting the tongue pieces to each other with a coupling pin. It is configured to be mounted on the game board with a press-fit pin.

  However, when an outer rail made of a synthetic resin is used, it is pointed out that static noise may occur due to the landing of a game ball on the outer rail, and a countermeasure for this is proposed (Patent Document 2).

  As shown in FIG. 14 (B), Patent Document 2 provides a conductive member in the vicinity of the landing point where the game ball fired by the launching unit of the outer rail lands, and is caused by the landing of the game ball on the outer rail. In this configuration, noise induction means for guiding the static noise generated by the operation from the conductive member to the outside of the pachinko machine is provided.

  However, in the technique of Patent Document 2, it is necessary to form the outer rail using a conductive member and a synthetic resin, or to attach the conductive member to a part of the synthetic resin rail, which increases the manufacturing cost. There is a problem. In addition, there is a problem in that the labor and time for assembly that the wiring for grounding must be grounded from the position where the launching device, the ball path, and the like at the lower part of the game board are attached are also increased.

  Various methods of grounding from the outer rail in gaming machines that employ metal outer rails have been proposed and patented for each method (Patent Documents 3 to 11).

  In Patent Document 3, as shown in FIG. 15A, a flat plate of a conductive elastic body formed of a conductive material based on natural rubber or the like is provided at the lower end portion of a guide body attached to the side portion of the outer rail. Mount the guide side plate so that it protrudes on both sides and is in close contact with the bottom surface of the outer rail, and the static electricity generated on the outer rail is transferred from the outer rail to the conductive elastic body to the metal lower front frame. Propose to escape.

  In Patent Document 4, as shown in FIG. 15 (B), a sheet metal conductive member is screwed and fixed to a boss projecting rearward from a sheet metal opening / closing plate pivotably attached to the front frame, When the front opening / closing door is closed, the convex side of the bent part of the conducting member is in sliding contact with the outer surface side of the outer rail when the front opening / closing door is closed. A structure that is pressed by the elastic force of the protruding portion is proposed.

  In Patent Document 5, as shown in FIG. 15C, when a conductive member is attached to the back side of a glass receiving rail formed by bending a sheet metal material and the glass door is closed, the convex side of the bent portion of the conductive member is outside. A conduction structure is proposed that is in sliding contact with the outer surface side of the rail and is pressed by the elastic force of the protruding portion.

  In Patent Document 6, as shown in FIG. 16A, a conductive member made of metal and bent into a substantially U-shape to form an elastic portion is attached to the upper left of the front frame, and this conductive member is attached to the elastic portion. A structure has been proposed in which the outer rail is brought into contact with the force, the outer rail is connected to the relay board via a conductive member, and can be grounded via the relay board.

  In Patent Document 7, as shown in FIG. 16 (B), a conductive guide rail is grounded to a lead wire via an elastic contact terminal, and the lead wire is arranged in a decorative member for an aesthetic appearance. We propose a structure that does not damage it.

  In Patent Document 8, as shown in FIG. 17A, a component mounting body including a band contact portion having a slit for fitting the inner band together with the outer band and the inner band is brought into contact with the connection fitting and the reaction body. It has been proposed to connect to a metal mechanism frame provided in the gaming machine frame.

  In Patent Document 9, as shown in FIG. 17 (B), a conductive grounding member protrudes from a base member arranged on the back side of the rail decoration to contact the rail, and the grounding member is connected to the grounding wire. The structure which covered with the lens member is proposed.

  In Patent Document 10, as shown in FIG. 18A, a sheet metal is attached so as to circumscribe the outer rail, a bent portion is formed on a metal surrounding plate attached to the back surface of the glass frame, and the glass frame is attached. It proposes a structure in which the bent portion and the sheet metal come into contact when closed.

  As shown in FIG. 18 (B), Patent Document 11 discloses an elastic conductive member formed by bending a leaf spring material when the front frame is closed on the front surface of the side edge outside the game area of the game board. In order to bring the outer rail into contact with the glass support frame when the door is closed, a structure is proposed in which the game board or the back set plate is screwed or welded to the glass support frame.

  These patented grounding methods are intended to remove static electricity charged on the game ball itself when transported in the game island by utilizing the fact that the outer rail is made of metal, and are made of synthetic resin. It is not a method to solve the problem that the rail is rubbed against the hit ball and is charged with static electricity, but only when the entire outer rail is integrally molded with a conductive resin as disclosed in Patent Document 2 as a deformation mode. I can't.

  Therefore, the present invention can accurately remove the static electricity charged on the synthetic resin side by rubbing against the hit ball when the outer rail is made of synthetic resin, and makes the installation of the parts complicated for that purpose. The purpose is to provide a gaming machine that does not have any.

A gaming machine of the present invention made to achieve such an object includes an outer rail that is attached to the surface of the game board and forms a ball striking path that guides a ball hit by a ball hitting device to a game area together with an inner rail. The gaming board is a gaming machine configured to be held and fixed to the inner frame by a fixture attached to a frame member constituting the inner frame, and is characterized by having the following configuration.
(1) The outer rail is composed of a synthetic resin molded product, and is structured to be attached by press-fitting into a pin hole on the game board surface by a press-fit pin integrally projected on the back side of the molded product. Being.
(2) A metal plate is fixed to the back surface of the synthetic resin molded product so that the tip protrudes toward the side surface of the game board.
(3) At least one of the fixtures attached to the inner frame has conductivity, and the conductive fixture has the metal plate when the game board is fixed to the inner frame. It is attached to the position where the tip of is sandwiched between the surface of the game board.
(4) An earth conducting member for grounding a fixture attached at a position where the metal plate is sandwiched between the surface of the game board is provided.

  According to the gaming machine of the present invention, the mounting of the outer rail can be performed by press-fitting a press-fit pin integrally projected on the back side as a synthetic resin molded product into the pin hole of the game board surface. Can be accurate. As a result of the accurate mounting position, the tip of the metal plate is also exposed on the game board surface at the designed position. Therefore, when the game board is assembled and held and fixed to the middle frame, a state of being sandwiched between the game board surface by the conductive fixture on the middle frame side can be accurately realized. Therefore, when the outer rail rubs against the hit ball, the static electricity accumulated in the synthetic resin parts constituting the outer rail is released from the metal plate to the ground conductive member through the conductive fixing on the inner frame side and removed. . In addition, since the structure is sandwiched between the conductive fixture and the game board, it is not necessary to bend the metal plate in a complicated manner to provide springiness, and the component processing cost does not increase.

The gaming machine of the present invention may further include the following configuration.
(5) The outer rail constitutes a side surface on the game area side of a synthetic resin frame decoration part in which at least the left and upper corner decorations of the corner decorations attached to the corners of the game board are connected and integrated. Similarly, it is formed integrally with the frame decoration part, and the press-fit pin is formed on the back surface of the frame decoration part.
(6) On the side of the game board side of the corner decoration of the frame decoration part, a hollow part that is recessed toward the direction of the game area is formed, and the metal plate is attached to the corner decoration so that the tip protrudes into the hollow part. It is fixed to the back of the.

  The frame decoration part in which at least the left and right corner decorations are connected and integrated means that a frame decoration part in which the right corner decoration is also integrated may be included. This is because the outer rail can cover up to the position where the outer ball jumps out to the game area as long as it is a frame decoration part in which at least the left and upper corner decorations are connected and integrated. And there are many merits such as making the outer rail sturdy by forming it integrally with the frame decoration part, and attaching the outer rail simultaneously by attaching the frame decoration part. In addition, a merit that a sufficient area can be taken on the back side of the synthetic resin molded product as a mounting position of the metal plate, and the formation of the spacer protrusion on the front frame side is easy to design by having a recess. There are also benefits. And

The gaming machine in which the frame decoration part and the outer rail are integrally formed may further have the following configuration.
(7) A cut portion is formed from the back at the edge of the recess portion of the corner decoration, and the tip of the metal plate has a back surface that protrudes from the cut portion to the recess portion. It is fixed to.

  By forming a notch at the edge of the corner ornament recess, the corner ornament can be mounted without lifting the corner from the game board surface. Because it can be.

These gaming machines of the present invention may further have the following configuration.
(8) A guide groove for guiding a hit ball is formed along a central portion of the rail width on the surface of the outer rail facing the inner rail.

  Since the hitting ball can be guided along the center part of the rail width of the outer rail by the guide groove, the course of the hitting ball can be stabilized. As a result of hitting the hit ball along the center of the rail width, rubbing with the hit ball occurs between the outer rail and the possibility of accumulation of static electricity on the outer rail increases. Does not cause any problems.

A gaming machine having a guide groove on the outer rail may further have the following configuration.
(8A) The guide groove of the outer rail is formed so that the depth of the groove gradually increases upward from a portion above the portion where the hitting position of the hit ball has exceeded a predetermined distance upward. thing.
A guide groove for guiding the hit ball is formed along the center portion of the rail width, and the vicinity of the landing position of the hit ball on the outer rail is a flat surface.

  Note that the portion of the outer rail that is a flat surface is not limited to the vicinity of the landing position, and the bottom surface may be a flat surface. According to the gaming machine of the present invention having such a configuration, the restriction by the guide groove is not so strong in the portion where the depth of the groove is shallow, and the depth of the groove gradually increases, so that Continuity is ensured and gradually adjusted to a state along the center of the rail width. As a result, a game ball with an unstable flight immediately after launching and landing is in a simple collision state and does not exert excessive regulatory force. The game ball collides with a glass plate or game board by smooth guidance. Thus, it is possible to prevent a stalling condition from occurring.

A gaming machine including an outer rail having a guide groove at the tip of a flat surface may further include the following configuration.
(8B) The guide groove has a cross-sectional shape having a laterally open slope with a flat portion extending toward the game board and a glass plate covering the game board with the center part of the rail width as the bottom of the groove. .

  By making the guide groove into a cross-sectional shape having a laterally laterally outward opening slope, that is, a laterally V-shaped groove, it is possible to smoothly hit the ball toward the center of the rail width. That is, the hit ball only touches at two points of the slope on the game board side and the slope on the glass plate side, so that it is difficult to stall and a smooth guidance can be realized.

Further, the hitting guide rail for gaming machines provided with the laterally V-shaped guide groove may further include the following configuration.
(8C) The guide groove is configured such that the groove depth gradually increases while the angle between the inclined surfaces remains the same.

  For example, there is a method of gradually increasing the V-shaped opening angle as a method of making a laterally V-shaped guide groove with a gradually increasing groove depth. There is a risk that the reaction of pressing works strongly and the movement of the game ball is made worse. On the other hand, by configuring the slopes of the V-shaped surfaces so as to gradually increase the groove depth while maintaining the same angle, it is possible to guide the hit ball while allowing the game ball to escape well along its launch direction. it can.

Moreover, the hitting guide rail for gaming machines provided with the outer rail having these guide grooves may further include the following configuration.
(8D) The guide groove is configured to extend to the end of the rail at a certain depth after being gradually deepened.

  For example, the game ball collides with the outer rail near the landing position, but after that, the contact state between the game ball and the outer rail is centrifugal from the position where the outer rail extends upward and begins to curve inward. This is because a stable state is obtained by the action of force, so that it is more desirable to keep a constant contact state than to deepen the groove in a direction in which outward force is released, and it is easy to design a curved shape.

In addition, a gaming machine including an outer rail having a guide groove may further include the following configuration.
(8E) The cross-sectional shape of the side surface on the game area side of the frame decoration part is a horizontal Y shape in the upper part from the part where the guide groove starts to be formed, and both edges in the width direction of the guide groove are free ends. Be configured in a cross-sectional shape.

  As a method of forming a guide groove serving as a V-shaped groove on the outer rail, the cross-sectional shape of the side surface on the game area side of the frame decoration part can be a laterally M-shaped. In that case, the mold is removed from the mold. There is a possibility that it will be necessary to use a movable core, etc. However, if it is Y-shaped sideways, it will be a plate-shaped molded body that spreads diagonally toward the front and back This is because it is not necessary to use a split core or the like. In addition, by adopting a horizontal Y-shape, the edge in the width direction of both the flat surface on the glass plate side and the flat surface on the game board side becomes a free end, and when the game ball is received, either the glass plate side or the game board side In addition, there is an advantage that a biased binding force is not generated. Thereby, guidance of a hit ball becomes smoother.

Further, the gaming machine including the outer rail integrally formed with the frame decoration part may further include the following configuration.
(9) The frame decoration component is configured in a box frame shape with an open back side, and the frame decoration is so configured that the side surface on the outer rail side is pressed from the back side into the space of the box frame portion. A spacer member that is separate from the part is installed.

  This is because the spacer member can reinforce the outer rail and is separate from the frame decoration part, so that the reinforcing position can be finely adjusted as appropriate within the box frame-shaped part. Thereby, even if the strength of the outer rail due to the synthetic resin is insufficient, this can be compensated.

The gaming machine reinforced with this spacer member may further include the following configuration.
(10) The spacer member is a synthetic resin integrated molded product including a strip-shaped flat plate portion and a rib protruding from the back surface of the flat plate portion.
(11) The space of the box frame-shaped part on which the spacer member of the frame decoration part is mounted is separated from the side surface on the outer rail side by a distance substantially the same as the plate thickness of the flat plate portion of the spacer member from the front side to the back side. The protrusion extending toward the side is formed integrally with the frame decoration part so as to straddle the landing position.

  Since the spacer member is constituted by the flat plate portion and the rib on the back surface, the spacer member can be mounted in a state having a bulge that bulges outward along the curvature of the outer rail. And it can maintain this bending state by attaching so that a flat plate part may be inserted | pinched between the some protrusion and the side surface which protruded so that it might straddle the landing position. Therefore, the spacer member accumulates bending stress in a direction to eliminate the bending, and the back side near the landing position of the outer rail can be firmly reinforced. In addition, the spacer member itself is reinforced by the ribs, and in the fine adjustment of the reinforced position, the rib member may be picked to shift the spacer member, and the adjustment work becomes easy.

  According to the present invention, when the outer rail is made of synthetic resin, static electricity charged on the synthetic resin side can be accurately removed by rubbing against the hit ball, and the mounting of the parts for that purpose is complicated. There is no.

In the range where the guide groove 21b is formed, the curved shape of the outer rail 21 is such that after the radius of curvature gradually increases upward from the lower end and extends almost vertically around the CC cross section, The radius of curvature toward the upper end gradually decreases, and the vicinity of the upper end has a curved shape with a substantially constant radius of curvature. Therefore, in other words, the portion above the BB cross section where the depth of the guide groove 21b is constant can be said to be a range where the centrifugal force of the game ball pq acts almost perpendicularly to the outer rail 21. The lower end of the guide groove 21b is continuous with the upper end of the flat portion 21a, and the guide groove 21b has the same angle between the inclined surfaces 21d and 21e so that the groove depth d = 0. The groove depth is gradually increased.

  In forming such a guide groove 21b, the cross-sectional shape of the side surface of the left frame decoration part 30 on the game area side is a horizontal Y-shape in a portion above the position R where the guide groove 21b starts to be formed with a sufficient depth. Thus, the inclined surfaces 21d and 21e are configured to have a cross-sectional shape in which both ends are free ends. For this reason, the left frame decoration part 30 has a shape in which the V-shaped front groove 21f is engraved on the front side of the upper part from the position R at which the guide groove 21b starts to sufficiently exhibit the function of guiding to the rail center. It can also be said. Note that the V-shaped front groove 21f has a groove width that is narrower toward the lower end side, as can be seen by comparing the CC cross section and the BB cross section. In addition, an elliptical recessed portion 21g for preventing sink marks at the time of injection molding is provided at the groove bottom of the guide groove 21b around the CC cross section. And the thickness of slope 21d, 21e is increasing gradually below the lower end of this recessed part 21g. This is because, as described above, when the groove depth d is gradually increased, the angle between the inclined surfaces 21d and 21e is the same angle. In addition, the portion below the position R at which the width adjustment starts substantially has a very small groove depth d in order to ensure continuity with the flat surface 21a, and is indicated by a dotted line in FIG. Similarly, the inclined surfaces 21d and 21e do not appear clearly, and are portions that do not substantially exhibit the guiding function. In the present embodiment, a cell return contact portion 21h is provided so as to project from the front surface immediately above the position R at which the width adjustment starts substantially. The cell return contact portion 21h is a member that receives the cell return A1 (see the hatched portion in FIG. 9) attached to the front frame side. As shown in FIG. 9, the cell return A <b> 1 is a part for preventing fraud by covering the out opening 15 and the vicinity of the cut Q between the firing rail G <b> 4 and the outer rail 21.

[7 Feature 3 of outer rail (reinforcement near the landing position)]
In the vicinity of the landing position N, as shown in FIGS. 10 to 12, the side surface on the outer rail 21 side is pressed from the back side into the space of the box-shaped part of the lower left corner decoration 32, A spacer member 50 separate from the left frame decoration part 30 is mounted. The spacer member 50 is a synthetic resin integrated molded product including a strip-shaped flat plate portion 51 and a rib 52 projecting from the upper back surface of the flat plate portion 51. Then, two pins 32p and 32p, a claw 32q, and an insertion hole boss 32r are directed toward the back surface as engaging members when the spacer member 50 is mounted on the back surface of the flat plate portion 32a of the lower left corner ornament 32. It protrudes integrally so as to extend.

  The pins 32p and 32p are provided with an interval to sandwich the rib 52 of the spacer member 50 therebetween. Further, the claw 32q and the insertion hole boss 32r are provided apart from the side surface on the outer rail 21 side by substantially the same distance as the plate thickness of the flat plate portion 51 of the spacer member 50. Further, pins 32p, 32p are formed at positions separated from the flat plate portion 51 of the spacer member 50 so as to support the upper end portion, the claw 32q, the intermediate portion, and the insertion hole boss 32r. Further, the claw 32q is located with respect to the straight line S contacting the outer rail side of the pins 32p, 32p and the insertion hole boss 32r, and the inner surface of the outer rail 21 facing the claw 32p is almost in contact with the straight line S. It is a positional relationship. Thereby, the flat plate portion 51 of the spacer member 50 is mounted in a state of being bent so as to bulge outward in accordance with the curved state of the outer rail 21.

  Therefore, the spacer member 50 accumulates bending stress in the direction to eliminate the bending, and acts as a member that firmly reinforces the back side of the outer rail 21 near the landing position N. Further, the ribs 52 increase the strength of the spacer member 50 itself. Further, as shown in FIG. 12, since the distance between the pins 32p and 32p and the inner surface of the outer rail 21 is larger than the plate thickness of the flat plate portion 51, the entire spacer member 50 is turned by picking the rib 52. By shifting in this manner, the reinforcing position can be finely adjusted to finely adjust the reinforcing force.

[8 Game board removal]
In the present embodiment, the game board 1 is fitted from the front side to the game board holding part B5 formed by the upper, lower, left and right frame members B1 to B4 of the middle frame B, and is attached to the upper and lower parts of the left frame member B3. The left edge is pressed down by the metal fixtures 61 and 61, and the right edge is pressed down by the synthetic resin fixtures 62 and 62 attached to the upper and lower portions of the right frame member B4. It is firmly held and fixed to the middle frame B.

  The metal fixtures 61, 61 are configured by clamp claw-like parts having a length reaching the depths of the upper and lower recesses 33, 34 of the left frame decoration part 30 of the game board 1. And the clamp nail-shaped metal fixtures 61 and 61 are parts rotated around the vertical axis so as to press down the left edge of the game board 1 at the positions of the recesses 33 and 34 of the left frame decoration part 30. It is attached to the left frame member B3. The pressed state is firmly maintained by the urging force of a spring member (not shown).

  The synthetic resin fixtures 62, 62 are each composed of a knob-shaped part that includes a support shaft extending in the horizontal direction and is rotated around the horizontal axis. The knob-shaped synthetic resin fixtures 62, 62 are rotated along the cut-out portion of the game board 1 on the right and up and down to the position where the knob protrudes toward the game board. Thus, the right edge of the game board 1 is pushed backward and is a component of a mechanism for firmly holding and fixing.

[9 Static electricity removal]
In the present embodiment, the metal is used so that the tips 71 a and 72 a protrude into the hollow portions 33 and 34 in the box-shaped space of the upper and lower corner decorations 31 and 32 of the left frame decoration part 30 constituting the outer rail 21. Plates 71 and 72 are attached. For this purpose, cut portions 31x and 32x are formed on the side walls 31b2 and 32b where the depressions 33 and 34 are formed from the back side. By providing the notches 31x and 32x, the metal plates 71 and 72 do not interfere when the left frame ornament part 30 is attached to the game board 1, and the left frame ornament part 30 is attached without being lifted. be able to. The left decorative part 30 has a structure that can be firmly attached to an accurate position by press-fitting the press-fit pin 41 into a hole formed on the game board 1 side.

  When the left frame decoration part 30 is attached to the game board 1 in this way, the metal plate tips 71a and 72a protrude into the recesses 33 and 34 as shown in FIG. When the game board 1 is assembled to the middle frame B, the metal plate tips 71a, 72a are sandwiched between the front surface of the game board 1 by the clamp claws-shaped metal fixtures 61, 61 of the middle frame. . Thereby, metal plate 71a, 72a and metal fixtures 61, 61 will be in a conduction state. In this embodiment, the frame members B1 to B4 of the middle frame B are also made of metal, and are grounded from the outer frame A to the game island via the frame members B1 to B4 of the middle frame B.

  As a result, even when a phenomenon occurs in which static electricity is accumulated on the outer rail 21 side when the metal game ball pq is guided while rubbing against the outer rail 21 made of synthetic resin, the metal on the back surface Static electricity can be removed from the outer rail 21 by grounding through the plates 71 and 72 and the metal fixing members 61 and 61. Thereby, it is possible to prevent the LED substrate and the like from being affected by static electricity, and to effectively solve the problem of static electricity accumulation newly generated by forming the outer rail 21 as an integrally molded product made of synthetic resin. . Moreover, the continuity for ground connection for this purpose is automatically established when the game board 1 is assembled to the middle frame B, and the metal plate tips 71a and 72a are connected to the surface of the game board 1 and the metal fixture. By being firmly sandwiched between 61 and 61, poor conduction is unlikely to occur, and it is not necessary to bend the metal plates 71 and 72 in a complex manner to give strong spring properties.

[10 Guidance of game balls jumping out to the game area]
In the present embodiment, as shown in FIG. 13, the upper rail 22 also constitutes the lower side surface (side surface on the game area side) of the nylon upper frame decoration component 80 that constitutes the upper right corner ornament 81 of the game board 1. In addition, the upper frame decoration part 80 is manufactured integrally with synthetic resin injection molding.

  In the upper frame decoration part 80, similarly to the left frame decoration part 30, the upper right corner decoration 81 and a part 82 of the upper left corner decoration are connected and integrated. The part 82 includes side wall portions 81b and 82b extending rearward from the peripheral edge portions of the front flat plate portions 81a and 82a, and is configured as a box-frame-like portion whose back side is open. The ends of the side walls 81b and 82b (the end face on the game board side) are flush with each other, and the upper side walls of the left and right corner decorations 81 and 82 are continuously integrated in a strip shape.

  Further, on the back side of the flat plate portions 81a and 82a of the corner decorations 81 and 82, press-fit pins 41 extending rearward and insertion holes 81c and 82c for inserting the positioning pins 42 are also formed.

  The upper rail 22 includes a guide groove 22b that guides the hit ball along the center of the rail width over the entire length thereof. This guide groove 22b has the same groove depth as the upper end of the guide groove 21b of the outer rail 21, and faces the glass board that covers the game board 1 and the game board 1 with the center part of the rail width as the groove bottom 22c. It has a cross-sectional shape having slopes 22d and 22e that are downwardly outwardly extending and have flat portions.

  In forming such a guide groove 21b, the cross-sectional shape of the side of the upper frame decoration part 80 on the game area side is a downward Y-shape, and the front ends of the inclined surfaces 22d and 22e are both free ends. ing. For this reason, the V-shaped front groove 22 f is formed on the front side of the upper frame decorative part 80.

  The upper frame decoration part 80 is attached to the correct position by press-fitting the press-fit pin 41 into the hole of the game board 1 in the same manner as the left frame decoration part 30. At this time, the left end edge of the upper rail 22 is attached to the upper end edge of the outer rail 21 so that the left end edge of the upper rail 22 does not protrude downward. As a result, the game ball that is guided by the outer rail 21 and jumps out does not collide with the left end portion of the upper rail 22, and is smoothly guided to the right. As a result, in a pachinko machine that has a jackpot digestion function by hitting to the right, the game ball that has been ejected vigorously into the game area 10 is moved to the right while being brought closer to the center of the rail width by the guide groove 22b of the upper rail 22. And can fly stably.

  In the present embodiment, the right rail 23 is also made of synthetic resin, and is configured as the left side surface of the right frame decoration part 90 that is injection-molded integrally with the right corner decoration. The right rail 23 is entirely composed of a flat surface, and no guide groove is provided. This is because the right rail 23 plays the role of partitioning the right side of the game area 10, and the guidance of the hitting ball is not particularly considered as the role. Note that the right frame decoration part 90 pops out so that the upper inner surface positively collides with the hit ball, unlike the case where the upper frame decoration part 80 is attached to the left frame decoration part 30 so as to hold it outward. It has a shape. This is because the right-handed hitting ball quickly changes its path downward and is well entangled with the obstacle nail provided on the right side so that the right-hand winning opening is awarded with an appropriate balance.

  The inner rail 24 is not integrated with the corner decoration, but is manufactured as a synthetic resin injection molded product. In addition to the role of forming the hitting ball guiding path L in cooperation with the outer rail 21, the inner rail 24 also has a role of partitioning the lower left side portion of the game area 10 and smoothly guiding the game ball to the out port 15. I'm in charge.

  According to the embodiment described above, the outer rail 21 can be attached by press-fitting the press-fit pin 41 integrally projected on the back side as a synthetic resin molded product into the pin hole on the game board surface. The mounting position can be made accurate. Since the surface of the outer rail 21 facing the inner rail 22 is a flat surface 21a in the vicinity of the landing position N, the impacted ball hits the flat surface with a single point on the flat surface. Then, after rising along the flat surface, the guide is guided in a state where the center of the trajectory is regulated by the guide groove 21b so as to pass through the center portion of the rail width. At this time, the restriction by the guide groove 21b is not so strong in the portion where the depth d of the groove is shallow, and the continuity with the flat surface 21a is ensured by gradually increasing the depth d of the groove. , Gradually adjusted to a state along the center of the rail width. As a result, the game ball pq in which the flight immediately after launching / landing is unstable is in a simple collision state and does not have an unreasonable regulatory force, and the game ball pq becomes a glass plate or game board by smooth guidance. It is possible to prevent the vehicle from colliding with 1 and causing a stall.

  In addition, by making the guide groove 21b into a cross-sectional shape having laterally open slopes 21d and 21e, that is, a laterally V-shaped groove, it is possible to smoothly hit the ball toward the center of the rail width. That is, the hit ball is only in contact with the slope 21d on the game board side and the slope 21e on the glass plate side, so that it is difficult to stall, and smooth guidance can be realized.

  Further, the slope 21d, 21e constituting the lateral V-shaped surface in which the groove depth d is gradually deepened is configured so that the groove depth d is gradually deepened while the same angle is maintained, so that the game ball pq is launched. The ball can be guided while escaping along the direction. Further, from the vicinity of the position where the outer rail 21 extends upward and begins to curve inward, the contact state between the game ball pq and the outer rail 21 becomes a stable state due to the action of centrifugal force, which is impossible for the game ball pq. It is possible to smoothly guide to the game area 10 without applying force.

  In addition, by making the right side surface of the left frame decoration part 30 and the lower surface of the upper frame decoration part 80 into a guide rail with a guide groove, the outer rail 21 and the upper rail 22 that play the role of guiding the game ball are sturdy. There is an advantage that the attachment of the outer rail 21 and the upper rail 22 can be performed simultaneously by the attachment of the frame decoration parts 30 and 80.

  Further, as a method of forming the guide grooves 21b and 22b to be V-shaped grooves, the cross-sectional shape of the side surface on the game area side of the frame decoration parts 30 and 80 is a Y-shaped cross section, so that it is divided as a mold for injection molding. A core or the like may not be used, and a guide rail with a guide groove can be manufactured at a low cost as an integrally molded product. In addition, by making the section Y-shaped, the slopes 21e and 22e on the glass plate side and the slopes 21d and 22d on the game board side are free ends, and when the game ball is received, the glass board side / game board side Therefore, the effect of smoothing the guidance of the hit ball is enhanced.

  Further, the outer rail 21 can be reinforced in the vicinity of the landing position N by the spacer member 50, and since it is separate from the left frame decoration part 30, the reinforced position can be finely adjusted as appropriate. Even if there is a lack of strength against the landing of the outer rail 21 due to the above, this can be compensated.

  The spacer member 50 is composed of the flat plate portion 51 and the ribs 52 on the back surface, and is mounted in a state where the pin 32p, the claws 32q, and the bosses 32r provided in the box-shaped space are bent along the curve of the outer rail 21. Therefore, the spacer member 50 accumulates bending stress in the direction to eliminate the bending, and the back side of the outer rail 21 near the landing position N can be firmly reinforced.

  In addition, since the outer rail 21 is made of a synthetic resin, static electricity is likely to be generated due to friction with the game ball pq, but the static electricity is removed through the metal plates 71 and 72 and the metal fixtures 61 and 61. In addition, the metal plates 71 and 72 for that purpose can be simply punched flat plates, and the work for assembling the game board 1 to the middle frame B is automatically secured for ground connection.

  And according to an Example, the pop-out position of a game ball can be stabilized using the synthetic resin hitting ball guide rail (outer rail) which can perform attachment work accurately and easily.

  As described above, the first embodiment has been described using the present invention as an embodiment. However, the present invention is not limited to this, and various modifications can be made without departing from the scope of the present invention.

  For example, in the embodiment, the outer rail 21 and the upper rail 22 are separate components, but the left and upper corner ornaments and the upper right corner ornament may be integrally formed, and the outer rail 21 and the upper rail 22 may be integral components. .

  Further, the metal plates 71 and 72 are not limited to flat plate punched products, and their tips 71a and 72a may be bent forward.

  Further, in the embodiment, the middle frame B is configured by an assembly in which the upper, lower, left and right frame members B1 to B4 are assembled, but may be a single frame.

  Further, for the conduction from the clamp claw-shaped metal fixtures 61, 61, a conductive path reaching the metal fixtures 61, 61 may be provided in addition to using the metal structure of the middle frame B. Absent.

  The present invention can be used in a pachinko machine.
