<Overall configuration of pachinko machine>
Hereinafter, an embodiment of the present invention will be described with reference to a pachinko gaming machine (hereinafter referred to as a “pachinko machine”) which is a kind of gaming machine. FIG. 1 is a perspective view of a pachinko machine 10 according to the first embodiment of the present invention, and FIG. 2 is a front view of a game board 20 provided in the pachinko machine 10.

  As shown in FIG. 1, the pachinko machine 10 is provided with a window portion 12 in which a transparent glass plate 11 is arranged in a pair at the front and rear at the center portion, and the game ball is placed on the front side through the window portion 12. The game board 20 (see FIG. 2) that flows down is visible to the player. Two lower and upper ball trays 13 and 14 are provided on the lower side of the window 12, and game balls are stored in the ball trays 13 and 14. A launch handle 15 is provided on the right side of the ball trays 13, 14. When the player operates the launch handle 15, the game balls stored in the upper ball tray 13 are placed one by one on the front side of the game board 20. Fired towards.

  As shown in FIG. 2, the game board 20 has a game area 21 formed in an inner portion of which the outer periphery is partitioned into a substantially circular shape. A center decorative member 22 and a plurality of side decorative members 23 are provided on the left and right sides of the center and lower part of the game area 21, and a large number of game nails are provided throughout the game area 21 avoiding the decorative members 22, 23. Is erected. In the game board 20 of the present embodiment, four types of game nails, that is, game nails 100A to 100C, and a game nail 100D (see FIG. 6) which is a part of the nail unit 200 are erected.

  In the area where the game nails 100A to 100D are provided, benefits are given to players such as the general prize opening 24, the start prize opening 25, 26, the variable prize winning device 27 that opens and closes the prize opening opened at the time of big hit, the through gate 28, etc. A winning ball is provided, and a winning ball is paid out when a game ball enters the inlet, or a lottery such as a big win is performed. As shown in FIG. 2, the game board 20 includes a wooden game board 50 that forms the outer shape of the game board 20, and a large number of game nails 100 </ b> A to 100 </ b> D are driven and attached from the surface side of the game board 50.

  The game board 50 is a plate-like member that holds the game nails 100A to 100D, and is formed of a single wooden board material or a plywood made by stacking a plurality of thin wooden boards. The game board 50 is not necessarily made of wood, and may be made of a synthetic resin plate material such as polycarbonate resin or acrylic resin, or an injection molded product.

  The game board 50 is provided with a through-hole to which a decorative member or the like is attached, and each member constituting the various winning ports 24 to 26, the variable winning device 27, the through gate 28, and the like is attached. In addition, a large number of game nails 100A to 100D are driven into and fixed to the game board 50 by a nailing device in a pre-formed hole 53 (see FIG. 3B). Note that it is not always necessary to provide the prepared holes 53 in advance and drive the game nails 100A to 100D into the game board 50. The game nails 100A to 100D may be driven into the game board 50 having a smooth surface. A slight dent may be provided on the surface, and the game nails 100A to 100D may be driven into the dent. Further, in the following description, the game nails 100A to 100D are driven into the prepared hole 53, and the holes that are deformed and enlarged by the game nails 100A to 100D are referred to as nail holes 52 compared to before the driving.

  Further, the game board 20 is provided with an outer rail 29a that is smoothly curved and erected from the lower left to the upper right of the game board 50; And an inner rail 29b provided. Both the outer rail 29a and the inner rail 29b are made of a thin metal plate. A plurality of game nails 100A are arranged from the left end of the game board 50 in the inner rail 29b to the upper left of the game board 50 along the outer rail 29a.

  The outer rail 29a guides a game ball that is launched from a launching device (not shown) with a strength corresponding to the operation amount of the launching handle 15 into the game area 21. A launch passage 31 through which a game ball fired from the launcher passes is formed in a portion between the outer rail 29a and the inner rail 29b or a plurality of game nails 100A arranged in front of the inner rail 29b in parallel. Is done. Therefore, the plurality of game nails 100 </ b> A arranged at the tip of the inner rail 29 b function as partition portions that partition the game area 21 and the launch passage 31.

  Here, in the pachinko machine 10, the operation and effect relating to the partition portion between the game area 21 and the launch passage 31 being constituted by a plurality of arranged game nails 100A will be described.

  As will be described later with reference to FIG. 3, the game nail 100 </ b> A has an elongated shaft portion 101 </ b> A (FIG. 3A) formed in a constant shape with a circular cross section perpendicular to the axial direction (longitudinal direction). ing. Therefore, the plurality of game nails 100A arranged at the tip of the inner rail 29b constitute partition portions having undulations on the respective sides of the game area 21 and the launch passage 31 due to the outer peripheral shape of the shaft portion 101A of each game nail 100A. To do. Therefore, the behavior when the game ball flowing down the game area 21 comes into contact with the partition portion (that is, the plurality of arranged game nails 100A) formed in an undulating shape on the game area 21 side is the inner rail 29b. Compared with the case where the thin plate is smoothly curved and is erected, it becomes complicated.

  In recent years, a central structure such as the center decoration member 22 disposed in the center of the game area 21 tends to be increased in size to improve the interest of the game. When the central structure is increased in size, the area where the game ball can flow down is limited accordingly. If the area where the game ball can flow is limited, the flow behavior of the game ball tends to be monotonous, and there is a possibility that the interest of the game that causes the game ball to flow down and wins a start prize opening or a general prize opening may be lost. It was. On the other hand, as described above, by arranging the plurality of game nails 100A as a partition portion for the game area 21, the behavior of the game ball that has come into contact with the partition section from the game area 21 side is complicated. Even when the game area is limited due to an increase in size of the structure, the flow-down behavior of the game ball is unlikely to be monotonous, and a suitable game interest can be provided.

  In addition, the partition portion (that is, a plurality of arranged game nails 100A) configured in an undulating shape also on the side of the launch passage 31 has a launch passage where game balls launched from the launch device do not reach the game area 21. Since the behavior of the backflowing game ball is complicated by the contact with the partition in the case of backflowing 31, the collision position between the backflowing game ball and the newly launched game ball from the launching device is indefinite. It becomes easy to become.

  Conventionally, when a game ball launched from the launching device does not reach the game area 21 and flows back through the launch passage 31, the game ball that flows backward from the launching device has a specific position with respect to the next game ball launched from the launching device. After being collided at the game area 21 and blown off to the game area 21 side, the cycle of reflowing again through the launch passage 31 and colliding with another game ball that has been launched next from the launcher at a specific position is cut off. There was a problem that it was difficult to return to the game. On the other hand, as described above, the partition portion that divides the game area 21 and the launch passage 31 is formed in an undulating shape on the launch passage 31 side, so that the game ball that flows backward through the launch passage 31 and the launch device The collision position with the newly launched game ball is likely to be indefinite, so that it is possible to return the game early after an event occurs in which the game ball flows backward through the launch path.

  In general, a rail such as an inner rail 29b that partitions the game area 21 and the launch passage 31 is fixed to the game board 50 by fixing the metal thin board at a predetermined interval by screwing or the like while smoothly curving the metal thin board. Since it was erected, there was a problem that it was easily distorted by use. When the rail that divides the game area and the launch passage is distorted, an appropriate game may be hindered, for example, a game ball flowing down the game area fits between the game nail and the rail. On the other hand, since the partition portion composed of a plurality of game nails 100A is less likely to be distorted in each game nail 100A, the partition portion is less likely to be distorted due to use, and an appropriate game can be provided over a long period of time. Can do.

<Game Nail 100A>
Next, with reference to FIG. 3, the structure regarding the game nail 100A which is a basic game nail is demonstrated. FIG. 3A is a longitudinal sectional view showing a fixed state between the game board 50 and the game nail 100A. FIG. 3B is a partially enlarged view showing the shape of the distal end side of the game nail 100A, and FIG. 3C is a cross-sectional view of the game nail 100A taken along the line AA in FIG. . FIG. 3D is a cross-sectional view of the game nail 100A taken along the line BB in FIG. In FIG. 3, for ease of understanding, FIG. 3A shows the game ball together with a solid line, and FIG. 3B shows a part of the pilot hole 53 at the front end in the depth direction. The outer shape is indicated by a two-dot chain line, and the shape of a part of the longitudinal cross section of the game nail 100A is indicated by hatching.

  As shown in FIG. 3A, the game nail 100 </ b> A is attached to the game board 50 so that one end side is held with respect to the game board 50 and protrudes to the front side where the front surface 51 of the game board 50 faces. . The side from which the game nail 100A protrudes corresponds to a game area provided on the front side of the game board 20, and the game ball flows down on the front side.

  As shown in FIG. 3A, the game nail 100A includes an elongated shaft portion 101A, and a tip end portion (protrusion end portion) that protrudes toward the front surface 51 side of the game board 50 on one end side of the shaft portion 101A. ) And a head portion 102 formed thicker than the shaft portion 101A. As shown in FIG. 3D, the shaft portion 101A of the game nail 100A is formed in a constant shape having a circular cross section perpendicular to the axial direction (longitudinal direction).

  The game nail 100A is made of metal, for example, is formed of brass (brass), and is formed by subjecting a wire material to a forging process such as rolling. Note that the game nail 100A is not necessarily formed by forging, but may be formed by using other processing such as cutting instead of or in addition to this.

  As shown in FIG. 3A, the game ball flowing down between the game board 50 and the glass plate 11 is a part of the shaft portion 101A and has a cross-sectional shape between the retaining portion 113 and the head portion 102. It abuts against the abutting portion 114 formed in a circular constant shape. The game nail 100A is mounted substantially perpendicular to the front surface 51 of the game board 50, and the game ball that comes into contact with the game nail 100A from above is guided to the game board 50 side, and the game nail 100A is played along the front surface 51 of the game board 50. The ball is configured to easily fall. Note that the fact that the game nail 100A is attached substantially perpendicularly to the front surface 51 of the game board 50 is not necessarily attached completely vertically, and is attached with a slight inclination (for example, within 5 degrees). For example, it may be attached so as to be inclined slightly upward from the horizontal.

  The shaft portion 101 </ b> A includes a tip end portion 111, a spiral portion 112, and a retaining portion 113 at the end opposite to the head portion 102. The game nail 100A is driven into the game board 50 from the tip part 111 side of the shaft part 101A, and the spiral part 112 and the retaining part 113 are positioned and fixed within the thickness of the game board 50. In the game nail 100A fixed to the game board 50, the head 102 and a part of the shaft part 101A protrude from the front surface 51 of the game board 50, and the protrusion amount from which the game nail 100A protrudes is, for example, approximately 18.5 mm. ing.

  The game nail 100A is driven into the game board 50 such that the side on which the front end portion 111 is located is the front end side in the driving direction (the right side in FIG. 3B) and the side closer to the head 102 is the rear end side in the driving direction. Fixed. The distal end portion 111 has a substantially circular cross-sectional shape with a diameter gradually increasing from the distal end side, and is positioned on the distal end side. The distal end side cusp portion 111a is located on the rear end side in the driving direction from the distal end side cusp portion 111a. It has the formed front end side straight part 111b.

  The tip-side cusp portion 111a has a substantially triangular shape in a side view perpendicular to the axial direction of the shaft portion 101A (viewed in the direction perpendicular to the paper surface in FIG. 3B), and is formed in a substantially conical shape. The distal straight portion 111b has a substantially circular cross-sectional shape with substantially the same diameter along the axial direction of the shaft portion 101A (the direction in which the central axis of the shaft portion 101A indicated by the one-dot chain line in FIG. 3B continues). Is formed.

  The tip end portion of the tip-side cusp portion 111a has an angle in a range of approximately 25 degrees to 30 degrees in a side view perpendicular to the axial direction of the shaft portion 101A (viewed in the direction perpendicular to the paper surface in FIG. 3B). It is set to be in contact with the back bottom surface 53a of the prepared hole 53 provided in the game board 50 in advance. Note that the distal end portion of the distal-side cusp portion 111a is preferably set to an angle of approximately 90 degrees or less in a side view, preferably set to an angle of approximately 60 degrees or less, and approximately 40 degrees or less. It is preferable to set the angle.

  Here, the pilot hole 53 is formed mainly from the front surface 51 of the game board 50 having a substantially identical diameter and a substantially circular cross-sectional shape. The diameter of the pilot hole 53 is smaller than the outer shape of the contact portion 114 within a range of about 10% to about 20%, and is the maximum outside of the distal end portion 111 (the distal end side sharp portion 111a and the distal end side straight portion 111b). It is formed slightly smaller than the diameter, and is set to about 1.5 mm, for example. The depth of the pilot hole 53 is longer than the length (for example, approximately 9 mm) from the most distal end of the game nail 100A in the driving direction to the rear end side in the driving direction where the retaining portion 113 is formed, and The game nail 100A is set to a length (for example, approximately 10 mm) shorter than a certain length (for example, approximately 2 mm or more) than the drive length (for example, approximately 15 mm) until the game nail 100A is driven into a proper position.

  The deep bottom surface 53a of the lower hole 53 is formed in a substantially conical shape having a substantially triangular shape in cross section so that the center portion has the deepest hole shape. In addition, the inclination angle of the back bottom surface 53a with respect to the central axis along the continuous axial direction of the pilot hole 53 is set to be larger than the inclination angle with respect to the central axis in the tip side cusp portion 111a of the game nail 100A. ing. When the game nail 100A is driven into the game board 50, the tip of the tip-side pointed portion 111a of the game nail 100A comes into contact with the back bottom surface 53a of the bottom hole 53, and then the bottom bottom 53a of the bottom hole 53 is touched. The tip of the game nail 100A is easily guided to the center side of the pilot hole 53 along the inclination. For this reason, the central axis of the game nail 100A easily matches the central axis of the pilot hole 53, and variations in the driving position of the game nail 100A in manufacturing can be reduced.

  The front end side straight portion 111b is formed in a substantially cylindrical shape in which the outer shape portion is substantially linearly continuous along the direction in which the shaft portion 101A of the game nail 100A continues. The front end side straight part 111b is a part for positioning the game nail 100A so that the shaft part 101A enters in parallel along the direction in which the pilot hole 53 continues, and the reference diameter (in the shaft part 101A of the game nail 100A) The diameter of the cylindrical portion having a smooth surface in the shaft portion 101A of the game nail 100A is preferably set to a length equal to or more than half of the diameter of the contact portion 114, and is set to a length equal to or greater than the diameter. Is preferred. Moreover, it is preferable to set the front end side straight part 111b to a shape in which the outer shape becomes slightly larger gradually. For example, the end of the front end side straight part 111b on the front side in the driving direction (side closer to the front end side sharp part 111a). Compared to the above, it is preferable that the rear end side (side closer to the spiral portion 112) in the driving direction is set to approximately 2% or more and the outer shape is set to be large, and it is preferable to set the outer shape to be approximately 5% or more and set to be large. It is. The tip-side straight portion 111b is not necessarily provided, and the spiral portion 112 may be continuous with the tip-side pointed portion 111a on the rear end side in the driving direction. Further, the maximum outer diameter of the tip portion 111 is set to be slightly smaller than the outer shape of the contact portion 114 within a range of about 5% to about 15% and slightly larger than the inner diameter of the pilot hole 53. , Approximately 1.7 mm.

  The spiral portion 112 is a portion that rotates the game nail 100A when the game nail 100A is driven into the game board 50, and the four spiral protrusions 112a are radially spaced away from the central axis by knurling. It is formed in a thread-like outer shape that protrudes. When the game nail 100A is driven into the pilot hole 53, the game nail 100A rotates along the continuous direction of the protrusion 112a, and this rotation causes the game nail 100A to extend along the continuous direction of the pilot hole 53. It becomes easy to proceed straight. Thereby, the variation in the driving position of the game nail 100A can be reduced.

  As shown in FIG. 3C, the protrusion 112a protrudes at a plurality of locations outward in the radial direction with respect to the central axis (point C in FIG. 3C). The protrusion 112a is provided at a plurality of positions in the circumferential direction centering on the central axis of the shaft 101A. As shown in FIG. 3 (b), the protruding tip portion of the ridge portion 112a is continuous along the axial direction of the shaft portion 101A so that the position centered on the central axis is a different position in the circumferential direction, The protruding portion 112a has a shape that continues spirally along the axial direction of the shaft portion 101A. In the spiral portion 112, the outer diameter (maximum outer diameter) where the tip of the protrusion 112a is located is set to be substantially the same along the axial direction of the shaft portion 101A, and is larger than the tip portion 111. Is set to

  Here, the length of the spiral portion 112 is preferably set to be equal to or longer than the diameter of the contact portion 114, and is preferably set to a length that is twice or more the diameter. is there. Further, the spiral portion 112 is preferably set to have a shape in which the outer shape is slightly increased gradually. For example, the spiral portion 112 is set in the driving direction in comparison with the end of the spiral portion 112 on the front end side (side closer to the front end portion 111). The outer shape of the rear end (the side close to the retaining portion 113) is preferably set to a large outer shape of about 5% or more, and is preferably set to a large outer shape of about 10% or more. It is preferable to set the degree of change in the outer shape of the spiral portion 112 at a larger ratio than the change in the outer shape of the tip-side straight portion 111b in order to reduce variation in the driving position of the game nail 100A. Note that the spiral portion 112 is not necessarily provided, and the retaining portion 113 may be continuous with the distal end portion 111.

  In addition, the width La of the protruding tip side portion of the protruding portion 112a of the spiral portion 112 is set to approximately one fifth of the diameter of the contact portion 114. The width La of the protruding portion 112a is preferably set within a range of about 1/10 to about 1/4 of the diameter of the contact portion 114. In addition, the direction in which the protruding portion 112a continues in the spiral portion 112 is, for example, approximately 45 degrees with respect to the central axis of the shaft portion 101A in the side view of the shaft portion 101A (viewed in the direction perpendicular to the paper surface in FIG. 3B). It is set to an inclined angle (inclination angle Ra), and the inclination angle Ra is preferably set to an angle within a range of approximately 25 degrees to approximately 60 degrees with respect to the central axis of the shaft portion 101A.

  The retaining portion 113 is provided on the rear end side in the driving direction with respect to the spiral portion 112 and is a portion that enters the game board 50 after the spiral portion 112 and prevents the game nail 100A from moving in the withdrawal direction side. . The retaining portion 113 is provided to be separated at two locations along the axial direction of the shaft portion 101A, and each has a constant cross-sectional shape in the circumferential direction around the central axis of the shaft portion 101A. The shape is continuous in a ring shape.

  Each of the retaining portions 113 protrudes in a substantially triangular shape on the outer peripheral side of the shaft portion 101A, and in the side view, the end portion on the rear end side in the driving direction (side closer to the head portion 102) is relative to the central axis of the shaft portion 101A. Projecting greatly in the radial direction. The cross-sectional shape of the end portion on the side close to the head portion 102 in the retaining portion 113 (the shape of the vertical cross section by a plane passing through the central axis of the shaft portion 101A) is formed at an acute angle where the protruding tip portion is sharper than a right angle. (See the shaded area in FIG. 3B). After the game nail 100A is driven into the game board 50, the retaining portion 113 is caught so as to pierce the inner surface of the nail hole 52, and the movement of the game nail 100A in the removal direction is prevented.

  As shown in FIG. 3A, the abutting portion 114 is a portion corresponding to a certain section on the side close to the head 102 in the shaft portion 101A, and has a circular cross-sectional shape and an outer peripheral shape of the same size. It is comprised by the column-shaped site | part. A part of the shaft portion 101A including the contact portion 114 as a part has a constant cross-sectional shape, and the outer diameter thereof is, for example, approximately 1.85 mm, and in the spiral portion 112 and the retaining portion 113. It is set to be thinner than the maximum outer diameter. Here, the maximum outer diameter of the spiral portion 112 and the retaining portion 113 corresponds to a virtual substantially cylindrical diameter that passes through the protruding end portion farthest from the central axis of the shaft portion 101A. For example, the maximum portion of the spiral portion 112 is set to 1.9 mm, and the retaining portion 113 is set to 1.95 mm.

  In addition, the position between the contact portion 114 and the retaining portion 113 in the shaft portion 101A and corresponding to the front surface 51 of the game board 50 (for example, a section approximately 13 mm from the tip on the tip portion 111 side) is included. It is preferable that a part of the contact portion 114 is harder than the contact portion 114 by work hardening by shot peening, drawing, or the like, thereby making it easy to ensure a long life against breakage of the game nail 100A. be able to.

  According to the gaming nail 100A configured in the above-described shape, the shaft portion 101A has a spiral portion 112 in which a protruding portion that forms a portion projecting larger than the contact portion 114 as a predetermined outer diameter spirally continues, Two retaining portions 113 provided at a plurality of locations separated from the spiral portion 112 toward the head 102 side are provided. For this reason, the game nail 100 </ b> A can easily secure a holding force larger than the holding force of only the spiral portion 112 by the plurality of retaining portions 113 being advanced into the prepared holes 53.

<Game Nail 100B>
Next, the game nail 100B will be described with reference to FIG. 4A is a side view of the game nail 100B, and FIG. 4B is a cross-sectional view of the game nail 100B taken along the line DD in FIG. 4A. FIG.4 (c) is a figure explaining the attachment aspect of the game nail 100B. In FIG. 4C, the shaft portions 101A, 101B (for each of the plurality of game nails 100A arranged between the game area 21 and the launch passage 31 and the game nails 100B attached in the vicinity thereof. More specifically, a cross section perpendicular to the axial direction (longitudinal direction) of each shaft portion in 101Ba) is shown.

  The game nail 100B is configured in the same manner as the game nail 100A described above except that a part of the shaft portion 101B is different from the shaft portion 101A. That is, a head 102 similar to the game nail 100A is formed at a tip end (protrusion end) projecting toward the front surface 51 side of the game board 50 on one end side of the shaft portion 101B. In addition, the shaft portion 101B includes a tip portion 111, a spiral portion 112, and a retaining portion 113 at the end opposite to the head portion 102, like the game nail 100A. The game nail 100B is attached to the game board 50 in the same manner as the game nail 100A shown in FIG. 3A, except that the attachment direction corresponding to the shape of the first shaft portion 101Ba is set.

  The game nail 100B is made of metal like the game nail 100A, and is formed of, for example, brass. The game nail 100B is formed by subjecting a wire rod to a forging process such as rolling, but it is not necessarily formed by a forging process. Instead of this, or in addition to this, other processes such as a cutting process are performed. You may form using the process of. Note that the first shaft portion 101Ba of the game nail 100B may be formed by cutting or the like after the tip portion 111, the spiral portion 112, the retaining portion 113, or the like is formed by forging, or may be formed by forging. Prior to forming 111, spiral portion 112, retaining portion 113, etc., they may be formed by cutting or the like.

  The shaft portion 101B includes a first shaft portion 101Ba set on the side close to the head 102 and a second shaft portion 101Bb set between the first shaft portion 101Ba and the retaining portion 113. . When the game nail 100B is driven into the game board 50, the first shaft part 101Ba is set on the front side of the game board 50 (that is, the position not inserted into the game board 50) and at the position including the contact part 114. Is done. That is, the game ball flowing down between the game plate 50 and the glass plate 11 contacts the contact portion 114 in the shaft portion 101Ba of the game nail 100B.

  The first shaft portion 101Ba and the second shaft portion 101Bb have different cross-sectional shapes perpendicular to the axial direction. Specifically, a cross section perpendicular to the axial direction of the second shaft portion 101Bb is formed in the same circular shape as the shaft portion 101A of the game nail 100A, whereas in the axial direction of the first shaft portion 101Ba. As shown in FIG. 4B, the cross section perpendicular to the circular arc portion 101Ba2 is a circular arc that is a semicircle of a circle that is substantially the same as the circle that is perpendicular to the axial direction of the second shaft portion 101Bb. And a straight circle 101Ba1 connecting both ends of the arc.

  As shown in FIG. 2, the game nail 100 </ b> B having the first shaft portion 101 </ b> Ba has a partition portion that partitions between the game area 21 and the launch passage 31 (more specifically, a plurality of arrays arranged ahead of the inner rail 29 b. Attached to the vicinity of the game nail 100A). As shown in FIG. 4C, in the game nail 100B, the straight portion 101Ba1 of the first shaft portion 101Ba faces the upper side of the game board 20 (game board 50) with respect to the arc portion 101Ba2, and the game area 21 And a direction of inclination that descends with increasing distance from the partition between the launch passage 31 (in this example, a direction extending in the lower right direction on the game board 20).

  Here, in the pachinko machine 10, the operation and effect of the game nail 100B configured in the above-described shape will be described.

  When a game nail (for example, a game nail 100A) having a shaft portion in which a cross-sectional shape of a portion where a game ball abuts is circular is attached in the vicinity of a partition that partitions between the game area 21 and the launch passage 31, Due to the shape of the shaft portion having a circular cross-sectional shape, the upper protrusion that contacts the game ball on the outer periphery of the shaft portion is almost directly above the shaft center of the shaft portion in the front view of the gaming machine. As a result, the separation distance between the shaft portion and the partition portion gradually decreases toward the lower side in the front view of the gaming machine, and the space between the shaft portion and the partition portion becomes like a pocket so that the game ball fits in There was a case.

  On the other hand, according to the pachinko machine 10 of the present embodiment, the game nail 100B in which the cross-sectional shape of the first shaft portion 101Ba including the contact portion 114 is a semicircle is used, and the game nail 100B is shown in FIG. By attaching as shown in FIG. 4, the portion of the outer periphery of the first shaft portion 101Ba that becomes the upper protrusion that comes into contact with the game ball (more specifically, close to the partition portion in the straight portion 101Ba1 of the cross section of the first shaft portion 101Ba) (The end on the side) is located on the side of the partition portion from directly above the axial center of the shaft portion 101B (the axial center of the second shaft portion 101Bb) in the gaming machine front view. As a result, the partition between the game area 21 and the launch passage 31 (in the present embodiment, the plurality of game nails 100A arranged) on the game area 21 side, and the first shaft portion 101Ba including the contact portion 114, In the meantime, it is difficult to form a space in which the game ball fits as described above. Thereby, it can suppress that the game ball which flows down the game area | region 21 fits between the partition part between the game area | region 21 and the discharge channel | path 31, and a game nail, and stops.

  Further, as shown in FIG. 4C, the game nails 100 </ b> B arranged adjacent to each other descend as the straight portion 101 </ b> Ba <b> 1 of each first shaft portion 101 </ b> Ba moves away from the partition portion between the game area 21 and the launch passage 31. It is attached as if to form an inclined surface. As a result, the surface including the straight portion 101Ba1 in each first shaft portion 101Ba of the adjacent game nail 100B separates the game ball flowing down in the vicinity of the partition portion between the game area 21 and the launch passage 31 from the partition portion. It can function as a route that promotes movement in the direction. Therefore, also in this respect, an event in which the game ball is fitted between the partition portion between the game area 21 and the launch passage 31 and the game nail can be suitably suppressed.

  Further, in the configuration in which the game nails 100B are arranged as shown in FIG. 4C, the game balls are guided in a direction away from the partition portion while jumping up in contact with the surface including the straight portion 101Ba1. At this time, the jumping direction of the game ball mainly follows the direction of the surface including the straight portion 101Ba1, so that the jumping direction can be controlled according to the direction of the surface including the straight portion 101Ba1.

  Note that the game nail 100B is used as an alternative to the game nails arranged in order to guide the game balls in a predetermined direction, such as a plurality of game nails (so-called guide nails) that guide the game balls to the start winning opening 25. May be. That is, a plurality of game nails 100B may be mounted side by side as if the straight portion 101Ba1 of the first shaft portion 101Ba forms a downward inclined surface in a predetermined direction (for example, a direction toward the start winning opening 25). Also in this case, by controlling the orientation of the surface including the straight portion 101Ba1, it is possible to control the direction in which the game ball is jumped in a predetermined direction by the arrangement of the plurality of game nails 100B. Therefore, for example, the game ball is allocated to the lower part of the center decoration member 22 in either a place where it is easy to enter the start winning opening 25 or a place where it is difficult to enter the start winning opening 25. When the split portion is provided, the orientation of the surface including the straight portion 101Ba1 is controlled so that the game ball can jump into the split portion, thereby being guided in a predetermined direction by the arrangement of the plurality of game nails 100B. A part of the game ball can be jumped into the distribution part, thereby improving the interest of the game.

<Game Nail 100C>
Next, the game nail 100C will be described with reference to FIG. FIG. 5A is a side view of the game nail 100C, and FIG. 5B is a cross-sectional view of the game nail 100C taken along line EE of FIG. 5A.

  The game nail 100C is configured in the same manner as the game nail 100A described above except that a part of the shaft 101C is different from the shaft 101A. That is, a head 102 similar to the game nail 100A is formed at one end side of the shaft portion 101C and at the tip end portion (protrusion end portion) protruding toward the front surface 51 side of the game board 50. In addition, the shaft portion 101C includes a tip portion 111, a spiral portion 112, and a retaining portion 113 at the end opposite to the head portion 102, like the game nail 100A. The game nail 100C is attached to the game board 50 in the same manner as the game nail 100A shown in FIG. 3A except that the attachment direction corresponding to the shape of the first shaft portion 101Ca is set.

  The game nail 100C is made of metal like the game nail 100A, and is made of, for example, brass. The game nail 100C is formed by subjecting a wire material to a forging process such as rolling, but it is not necessarily formed by a forging process. Instead of this, or in addition to this, other processes such as a cutting process are performed. You may form using the process of. Note that the first shaft portion 101Ca of the game nail 100C may be formed by cutting or the like after forming the tip portion 111, the spiral portion 112, the retaining portion 113, and the like by forging, or may be formed by forging processing. Prior to forming 111, spiral portion 112, retaining portion 113, etc., they may be formed by cutting or the like.

  In addition, the shaft portion 101C includes a first shaft portion 101Ca set on the side close to the head 102, and a second shaft portion 101Cb set between the first shaft portion 101Ca and the retaining portion 113. . When the game nail 100C is driven into the game board 50, the first shaft part 101Ca is set on the front side of the game board 50 (that is, the position not inserted into the game board 50) and the position including the contact part 114. Is done. That is, the game ball flowing down between the game board 50 and the glass plate 11 contacts the contact part 114 in the shaft part 101Ca of the game nail 100C.

  The first shaft portion 101Ca and the second shaft portion 101Cb have different cross-sectional shapes perpendicular to the axial direction. Specifically, the cross section perpendicular to the axial direction of the second shaft portion 101Cb is formed in the same circular shape as the shaft portion 101A of the game nail 100A, whereas in the axial direction of the first shaft portion 101Ca. As shown in FIG. 5 (b), the cross-section perpendicular to the circular arc of a portion smaller than a semicircle in a circle that is substantially the same as the circle that is perpendicular to the axial direction of the second shaft portion 101Cb, Each arc extends from both ends 101Ca2 and 101Ca3 of the arc, and is surrounded by straight lines that intersect at intersections (vertex 101Ca1) on a circle that is a cross section perpendicular to the axial direction of the second shaft portion 101Cb.

  As shown in FIG. 2, the game nail 100 </ b> C having the first shaft portion 101 </ b> Ca is attached to the vicinity of the exit of the launch passage 31 in the game area 21. At this time, the game nail 100C is attached in such a direction that the vertex 101Ca1 of the first shaft portion 101Ca faces the upper side of the game board 20 (game board 50).

  Here, in the pachinko machine 10, an operation and an effect relating to the game nail 100C configured in the above shape will be described.

  The pachinko machine 10 may be cheated by launching a game ball with a thread attached into the game area.

  On the other hand, according to the pachinko machine 10 of the present embodiment, the game nail 100C attached in the vicinity of the exit of the launch passage 31 is attached in such a direction that the vertex 101Ca1 of the first shaft portion 101Ca faces upward. When a game ball with a thread attached is fired, the game ball easily hangs in a state where the thread straddles the vertex 101Ca1 of the game nail 100C and uses the vertex 101Ca1 as a fulcrum.

  When the yarn is pulled or loosened in such a state, the yarn is rubbed by the corner portion of the vertex 101Ca1, so that the yarn attached to the game ball can be easily broken by friction with the corner portion. In particular, as shown in FIG. 5B, in the cross section perpendicular to the axial direction of the first shaft portion 101Ca, the angle of the vertex 101Ca1 is an acute angle, so the effect of cutting the thread attached to the game ball Is preferably improved.

  In addition, since the game nail 100C has a simple cross-sectional shape of the first shaft portion 101Ca, the game ball rebounds characteristically according to its contact position (collision position). Therefore, it is possible to improve the interest in the behavior of the game ball rebounding by the game nail 100C. In particular, in this embodiment, the game nail 100C is configured such that the cross-sectional shape of the first shaft portion 101Ca including the contact portion 114 has a corner portion that is bent at the vertex 101Ca1, and the corner portion of the game board 20 is the corner portion. Since it is attached to the vicinity of the exit of the launch passage 31 so as to face upward, the rebound behavior by the game nail 100C can be complicated for the game ball that has entered the game area 21 from the launch passage 31. Therefore, it becomes possible for the player to entertain the behavior of the game ball that has entered the game area 21 from the launch passage 31.

<Nail unit 200>
Next, the nail unit 200 including the game nail 100D will be described with reference to FIG. FIG. 6A is a side view of the nail unit 200 viewed from the direction in which the longitudinal direction of the connecting portion 201 is viewed. 6B is a side view of the game nail 100D viewed in the direction of arrow G in FIG. 6A, and FIG. 6C is a view of the game nail 100D taken along line FF in FIG. 6A. It is sectional drawing. FIG. 6D is a side view of the connecting portion 201 viewed in the direction of arrow H in FIG. In FIG. 6A, the front surface 51 of the game board 50 when the nail unit 200 is attached to the game board 50 is indicated by a two-dot chain line.

  As shown in FIG. 6A, the nail unit 200 is configured as a unit in which two game nails 100D are connected by a connecting portion 201. The connecting portion 201 is formed with a rod-like protruding portion 201a that is elongated along the axial direction of the game nail 100D at a position between the two game nails 100D. The number of protrusions 201a included in one nail unit 200 is not limited to five as shown in FIG. 6A, but depends on the distance between the game nails 100D at both ends constituting the nail unit 200. The number is one or more appropriate numbers.

  The nail unit 200 having the protruding portion 201a includes a plurality of game nails arranged (arranged) in series, for example, a plurality of game nails (so-called so-called nails) for guiding a game ball to the start winning opening 25 as shown in FIG. , Can be attached instead of a guide nail). That is, the protrusion 201a can be used as a member that replaces a part of the game nails arranged in a row. Therefore, by providing an appropriate number of protrusions 201a between the two game nails 100D at both ends, various types of nail units 200 that can be used as substitutes for game nails arranged in a row such as a guide nail are prepared. can do.

  Further, the nail unit 200 does not necessarily include the protruding portion 201a, and the connecting portion 201 may not include the protruding portion 201a. For example, in this embodiment, as shown in FIG. 2, a pair of game nails (so-called life nails) functioning as the entrance of the winning opening 25 are attached in the form of a nail unit 200 above the upper starting winning opening 25. The projecting portion 201a is not formed on the connecting portion 201 of the nail unit 200 corresponding to the pair of game nails.

  The game nail 100D constituting the nail unit 200 is configured in the same manner as the game nail 100A described above except that the groove portion 155 is formed in the shaft portion 101D. That is, a head portion 102 similar to the game nail 100A is formed at the tip end portion (projection end portion) that protrudes toward the front surface 51 side of the game board 50 on one end side of the shaft portion 101D. Further, like the game nail 100A, the shaft portion 101D includes a tip portion 111, a spiral portion 112, and a retaining portion 113 at the end opposite to the head portion 102. The game nail 100D is the same as the game nail 100A shown in FIG. 3A, except that the mounting direction is set so that the longitudinal direction of the connecting portion 201 matches the direction in which the groove 115.116 extends. And attached to the game board 50.

  The game nail 100D is made of metal like the game nail 100A, and is formed of, for example, brass. The game nail 100D is formed by subjecting a wire material to a forging process such as rolling, but it is not necessarily formed by a forging process. Instead of this, or in addition to this, other processes such as a cutting process are performed. You may form using the process of. The groove portions 115 and 116 in the shaft portion 101D of the game nail 100D may be formed by cutting or the like after forming the tip portion 111, the spiral portion 112, the retaining portion 113, and the like by forging. Before the tip portion 111, the spiral portion 112, the retaining portion 113, and the like are formed, they may be formed by cutting or the like.

  Further, groove portions 115 and 116 are formed in the shaft portion 101D at a position closer to the distal end portion 111 side than the contact portion 114 and in front of the front face 51 when the game nail 100D is driven into the game board 50. ing. As shown in FIGS. 6 (a) and 6 (b), the groove 115 has an axis extending in the direction in which the connecting portion 201 extends (the horizontal direction in FIG. 6 (a) and the direction perpendicular to the paper in FIG. 6 (a)). This is a groove formed by cutting out the portion 101D. On the other hand, the groove part 116 is formed at a position on the back side of the groove part 115 with respect to the axial direction of the shaft part 101 and is formed by cutting the shaft part 101D in a direction (longitudinal direction) in which the connecting part 201 extends. It is a groove that makes.

  In the shaft portion 101D of the game nail 100D, the portion where the pair of groove portions 115 and 116 are formed is perpendicular to the axial direction as compared to the portion where the groove portions 115 and 116 are not formed, as shown in FIG. Since a simple cross section is thinned by the depth of the grooves 115 and 116, breakage or breakage is likely to occur. In particular, since the pair of groove portions 115 and 116 extending in substantially the same direction is formed, the shaft portion 101D has directivity with respect to a load in a specific direction, that is, is perpendicular to the shaft portion 101D, and the groove portion 115. , 116 with respect to the direction perpendicular to the direction, the load tends to break.

  Further, in the present embodiment, when the nail unit 200 is attached to the game board 50, the positions where the grooves 115 and 116 are formed are forward of the front face 51 of the game board 50 and closer to the front face 51 than the head 102. It is set to become. In this way, by setting the positions of the grooves 115 and 116 when the nail unit 200 is attached to the game board 50 to be closer to the front surface 51 than the head 102, the game nail can be removed by improperly applying force to the head 102. When bending is attempted, the groove portions 115 and 116 are relatively close to the front surface 51 of the game board 50 serving as a fulcrum with respect to the position where the force is applied (that is, the power point). The shaft portion 101D is easily damaged at the groove portions 115 and 116.

  In particular, the position of the grooves 115 and 116 when the nail unit 200 is attached to the game board 50 is set to a position of a predetermined length (for example, about 5 mm) from the front surface 51 of the game board 50 to the axis. Even when the portion 101D breaks in the groove portions 115 and 116, the game nail 100D is left in a state where it protrudes from the front surface 51 of the game board 50 by a predetermined length, so that the game nail 100D is removed from the game board 50. It is easy to do.

  The connecting portion 201 constituting the nail unit 200 is made of metal, and is formed of, for example, brass. The connecting portion 201 is formed into a desired shape by cutting or molding. As shown in FIG. 6 (d), the connecting part 201 is formed with recesses 201b at both ends in the longitudinal direction for fitting and fixing the game nail 100D. Therefore, the nail unit 200 is created by fitting and fixing the two game nails 100D in the recesses 201b of the connecting portion 201, respectively.

  The recess 201b includes an opening 201b1 serving as an entrance for introducing the game nail 100D and a fitting portion 201b2 provided continuously to the opening 201b1. The opening 201b1 is configured to have a size capable of introducing the game nail 100D, and the size of the opening 201b1 becomes narrower as it approaches the fitting portion 201b2.

  On the other hand, the fitting portion 201b2 has an inner diameter that is approximately the same as the outer diameter of the portion of the game nail 100D that is fitted into the fitting portion 201b2 (in this embodiment, the end portion of the shaft portion 101D on the side close to the head 102). Then, it is formed as a semicircle or more arc that is open to the extent that it can accept the game nail 100D that has entered from the opening 201b1. Therefore, the game nail 100D fitted in the fitting part 201b2 is fixed to the fitting part 201b2 in a state where it is difficult to come off.

  As described above, the connecting portion 201 is provided with one or more protruding portions 201a as needed between the two game nails 100D, that is, between the concave portions 201b formed on both sides. The The projecting portion 201a is configured as a substantially cylindrical rod-like body having a circular cross-section with the same diameter as the cross-section of the shaft portion 101D and an outer peripheral shape of substantially the same size.

  As shown in FIG. 6A, the length of the protrusion 201a is such that the tip of the protrusion 201a does not contact the front surface 51 of the game board 50 when the nail unit 200 is attached to the game board 50 (for example, , About a few millimeters from the front surface 51 to the front side). That is, when the nail unit 200 is attached to the game board 50 by the game nails 100D at both ends, a slight gap is formed between the protruding portion 201a and the front surface 51.

  Here, in the pachinko machine 10, the operation and effect of the nail unit 200 having the above configuration will be described.

  In the pachinko machine 10, a part of the large number of game nails attached to the game board 50 is attached in the form of the nail unit 200, and therefore the bending direction of the two game nails 100 </ b> D constituting the nail unit 200. The degree of freedom is regulated by the presence of the connecting portion 201 that connects these game nails 100D. Therefore, since it becomes difficult for the nail unit 200 to bend the game nail 100D in an unauthorized manner, an illegal act can be suppressed.

  In addition, by attaching a pair of game nails provided above the start winning opening 25 in the form of the nail unit 200, the interval between the pair of game nails is fixed by the connecting portion 201. It is difficult to widen the distance between the pair of game nails so that entry) is easy. Therefore, it is possible to suppress an illegal act of increasing the distance between the pair of game nails. Similarly, it is difficult to narrow (close) the pair of game nails.

  When the nail unit 200 is attached to the game board 50, a protruding portion 201a whose tip is slightly separated (floated) from the front surface 51 is formed between the two game nails 100D at both ends. ing. Therefore, the protruding portion 201a can be bent in a state where the nail unit 200 is attached to the game board 50.

  Therefore, when the nail unit 200 in which the protruding portion 201a is formed is used instead of a plurality of game nails (so-called guide nails) for guiding the game ball to the start winning opening 25 as shown in FIG. When the game ball guided along the connecting portion 201 comes into contact (collides), the protruding portion 201a bends. Due to the bending of the protruding portion 201a, it is possible to easily bounce the game ball guided along the connecting portion 201 on the nail unit 200.

  Therefore, for example, the game ball is allocated to the lower part of the center decoration member 22 in either a place where it is easy to enter the start winning opening 25 or a place where it is difficult to enter the start winning opening 25. When the split portion is provided, a part of the game ball guided to the start winning opening 25 by the nail unit 200 can be jumped into the sort portion, thereby improving the interest of the game.

  Also, in the nail unit 200, the game nail 100D is attached so that the direction in which the groove 115 extends and the longitudinal direction of the connecting portion 201 coincide with each other. The appearance will change greatly. Therefore, an illegal act of bending by applying a load to the game nail 100D or the like can be detected early by a change in appearance. In addition, since fraudulent acts are easily discovered in this way, the implementation of the fraud is suppressed.

Second Embodiment
Next, a second embodiment will be described with reference mainly to FIG. In the pachinko machine 10 according to the first embodiment described above, a plurality of game nails functioning as entrances of the entrances are driven into the game board 50 above the entrances such as the start winning opening 25 and the through gate 28. It is. For example, two game nails 100D (a part of the nail unit 200) functioning as the entrance of the start winning opening 25 are driven above the starting winning opening 25.

  On the other hand, in the pachinko machine 10 according to the second embodiment, a part of the plurality of game nails functioning as the entrance to the entrance is not driven into the game board 50 and the entrance is formed. It is integrated with the ball device. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and portions different from those in the first embodiment are described.

  FIG. 7A is a front view of a general winning device 334, which is one of the ball entry devices, attached in the first attachment manner, and FIG. 7B is attached in the second attachment manner. It is the front view of the general prize winning device 334.

  In FIG. 7A and FIG. 7B, a general function that functions as an entrance of a general winning port 324 that is a ball entrance in the general winning device 334 together with a pin 401 provided in the general winning device 334. Three game nails Q1 to Q3 provided in the vicinity of the winning device 334 are shown together. The game nails Q1 to Q3 are, for example, the game nails 100A described above. The game nails Q1 to Q3 are not limited to the game nail 100A but may be any of the game nails 100B to 100D. Further, the game nails Q1 to Q3 may not all be game nails having the same shape.

  The general winning port 324 is a winning port that functions in the same manner as the general winning port 24 of the first embodiment, and when a game ball enters (passes), the prize ball is paid out as a bonus. The general winning device 334 is a winning device in which a general winning port 324 is formed. The general winning device 334 includes a main body 324a having a general winning opening 24 formed on the upper side, and a base plate 334b connected to the back side of the main body 324a. Inside the main body 324a, a game ball that is connected to the general winning port 324 and enters the general winning port 324 (passed through the general winning port 324) is sent to a discharge path formed on the back side of the game board 50. A passage for this is formed. The entrance side of the general winning opening 324 in the base plate 334 b is formed in a slope shape from the outer edge side of the base plate 334 b toward the general winning opening 324 so that the game balls can smoothly enter the general winning opening 324.

  The base plate 334b is formed with two insertion openings through which the screws 301 and 302 for attaching the general winning device 334 to the game board 50 are inserted. More specifically, in a state in which the general winning opening 324 is directed almost directly above the gaming machine front view (that is, the state shown in FIG. 7A), the vertical axis passing through the center of the general winning opening 324 is shown. A first insertion port for inserting the screw 301 is formed in the upper left portion. On the other hand, in the same state, a second insertion port through which the screw 302 is inserted is formed in the lower part on the right side of the vertical axis passing through the center of the general winning port 324.

  The game board 50 has a stop hole 54 for fixing the screw 301 passed through the first insertion port of the base plate 334b. On the other hand, the game board 50 is provided with two stop holes 55 and 56 as stop holes for fixing the screws 302 passed through the second insertion port of the base plate 334b.

  Therefore, the mounting direction of the general winning device 334 can be changed depending on whether the fixing destination of the screw 302 passed through the second insertion port is the stop hole 55 or the stop hole 56. That is, when the screw 302 passed through the second insertion port is fixed by the stop hole 55, the general winning device 334 has the general winning port 324 substantially in the front view of the gaming machine as shown in FIG. It is attached to face up.

  On the other hand, when the screw 302 passed through the second insertion port is fixed in the stop hole 56, the general winning device 334 rotates clockwise around the stop hole 54 from the state shown in FIG. It is attached in the state that was done. Therefore, the general winning device 334 attached using the stop hole 56 is attached so that the general winning port 324 faces the upper right in the front view of the gaming machine, as shown in FIG. 7B.

  At the time of manufacture, the general winning device 334 is attached to the game board 50 by screwing the screw 302 passed through the second insertion port into one of the stop holes 55 or 56. At this time, the other stop hole that is not used is filled by pouring resin. In this way, by selecting the stop hole 55 or the stop hole 56 as a fixing destination of the screw 301 passed through the second insertion port, it is possible to manufacture a gaming machine in which the opening direction of the general winning port 324 is different.

  Of the stop holes 55 or 56, the stop holes that are not used for mounting the general winning device 334 may be configured to be temporarily fixed using a temporary fixing member, or may be opened as they are. Also good.

  A pin 401 is erected on the base plate 334b at a position on the upper right of the general winning opening 324. The pin 401 is configured in the same shape as the portion on the head 102 side from the retaining portion 113 in the game nail 100A described above. That is, the pin 401 has a shaft portion that is elongated in a constant shape with a circular cross-sectional shape, and a head portion that is thicker than the shaft portion on one end side of the shaft portion. The end portion of the shaft 401 opposite to the head portion of the pin 401 is fixed to the base plate 334b.

  As described above, the mounting direction of the general winning device 334 can be changed depending on whether the stop hole 55 or the stop hole 56 is used. Thereby, the relative position of the pin 401 with respect to the game nails Q1 to Q3 changes. For example, when the general winning device 334 is attached using the stop hole 56 (FIG. 7B), the game nail Q1 and the pin 401 are compared to the case where the stop hole 55 is used (FIG. 7A). And the distance becomes wider. Since the distance between the game nail Q1 and the pin 401 is increased, the game ball can easily enter the general winning opening 324 accordingly.

  When the general winning device 334 is attached using the stop hole 55, the game balls flowing down from the upper left side are placed between the game nail Q1 and the game nail Q2 to the general prize opening 324 depending on the arrangement of the game nails Q2 and Q3. There was only a route to guide. On the other hand, when the general winning device 334 is attached using the stop hole 56, the distance between the game nail Q3 and the pin 401 is larger than that when the stop hole 55 is used. Not only between Q1 and the game nail Q2, but also between the game nail Q3 and the pin 401, it can be a route for guiding the game ball flowing down from the upper right side to the general winning opening 324. Thus, the number of entrances to the general winning opening 324 is increased to two, so that the game ball can easily enter the general winning opening 324 also in this respect.

  Here, the operation and effect of the pachinko machine to which the general winning device 334 of the second embodiment described above is attached will be described.

  As described above, the general winning device 334 enters the general winning port 324 according to whether the stop hole 55 or the stop hole 56 is used as a fixing destination of the screw 302 passed through the second insertion port. You can change the ease of the ball. Further, as shown in FIGS. 7A and 7B, the direction in which the general winning device 334 is attached has changed, so that the direction in which the game ball is driven to win the general winning opening 324 is also changed. It becomes possible. As described above, according to the second embodiment, by selecting the stop hole to be fixed to the screw 302 passed through the second insertion port among the stop holes 55 and 56 at the time of manufacture, the general winning device 334 Pachinko machines 10 having different attachment modes can be manufactured. Therefore, it is possible to easily manufacture two types of different gaming machines having two types of different gaming characteristics.

  Further, the pin 401 has a relatively weak attachment strength because one end of the elongated shaft portion is fixed to the base plate 334b. Therefore, the pin 401 easily falls off the base plate 334b when an improper load is applied to bend the pin 401. Since the pin 401 is a member integrated with the general winning device 334 by being fixed to the base plate 334b, the appearance of the general winning device 334 changes when the pin 401 is dropped. A device having a entrance (for example, a general prize opening 324) that grants a privilege such as a prize ball by passing a game ball, such as the general winning device 334, is easily noticeable and sensitive to changes in appearance. It becomes. Therefore, an illegal act performed on the pin 401 so as to favor the entry (entrance) of the game ball into the general winning opening 324 can be detected at an early stage by a change in the appearance of the general winning device 334. Moreover, since it becomes easy to find the fraudulent act for making the game ball entry into the general winning opening 324 advantageous, the execution of the fraud is suppressed.

  Even if it is difficult to cheat the pin 401, the game ball to the general winning opening 324 is bent by bending other gaming nails that function as the entrance of the general winning opening 324 together with the pin 401, such as the game nail Q1. However, since it is difficult to bend the pin 401, it is necessary to bend other game nails such as the game nail Q1 greatly. However, since the game nail is greatly bent, it becomes easy to find that the game nail is bent, and in this respect also, illegal acts for making the game ball enter the general winning opening 324 advantageous. Easy to find.

<Third Embodiment>
Next, a third embodiment will be described with reference mainly to FIG. In the pachinko machine 10 according to the first embodiment described above, a pair of game nails (game nails 100D) that function as the entrances of the start winning opening 25 are attached in the form of the nail unit 200, thereby the game nails that function as the entrances. It was set as the structure which suppresses the illegal bending with respect to 100D.

  On the other hand, in the pachinko machine 10 according to the third embodiment, for the pair of game nails functioning as the entrance of the start winning opening, by surrounding (covering) the front end portion of each game nail with a nail cover, Incorrect bending of the pair of game nails is suppressed. The same components as those in the first and second embodiments are denoted by the same reference numerals, description thereof will be omitted, and portions different from those in the above embodiments will be described.

  FIG. 8A is a front view of the start winning device 535, and FIG. 8B is a cross-sectional view of the start winning device 535 along the line JJ in FIG. 8A. In FIG. 8, a pair of game nails Q4 and Q5 which are provided above the start winning device 535 and function as the entrance of the start winning port 525 are shown together.

  In the example shown in FIG. 8, the pair of game nails Q4 and Q5 is the game nail 100A described above. The game nails Q4 and Q5 are not limited to the game nail 100A but may be any of the game nails 100B to 100D. Further, both the game nails Q4 and Q5 may not be the same shape game nails.

  The start winning device 535 is a resin winning device in which a start winning port 525 is formed. The start winning device 535 is configured to be transparent so that at least the front side of the housing portion 535b1 can visually recognize the game nails Q4 and Q5. The front side of the accommodating portion 535b1 may be translucent. The start winning device 535 includes a main body portion 535a that forms the main body of the start winning device 535, and a nail cover portion 535b that is continuously provided above the main body portion 535a in the front view of the gaming machine.

  The main body 535a is configured in a box shape in which an upper surface and a back surface (a surface facing the game board 50) in a front view of the gaming machine are opened. An attachment portion 535a2 for attaching the start winning device 535 to the game board 50 is provided on the outer peripheral wall of the main body portion 535a. In the example shown in FIG. 8, the attachment portions 535a2 are provided at three locations, the outer peripheral wall 535a3 on both the left and right sides of the main body 535a in the front view of the gaming machine, and the outer peripheral wall 535a4 on the bottom side.

  The attachment portion 535a2 has an insertion port through which the screw 501 can be inserted. The start winning device 535 is attached to the game board 50 by fixing the main body 535a to the game board 50 with a screw 501 inserted through the insertion port of the attachment part 535a2.

  One of the spaces surrounded by the front outer peripheral wall 535a5, the bottom outer peripheral wall 535a4, and the left and right outer peripheral walls 535a3 (hereinafter referred to as "internal space of the main body 535a") in the main body 535a in the front view of the gaming machine. The game ball that has entered the start winning device 535 from the opening above the main body 535a is guided to a discharge path (not shown) formed on the back side of the game board 50 (the surface that is the back side of the front surface 51). It functions as a ball passage.

  More specifically, each inner wall of the left and right outer peripheral walls 535a3 has a rib 535a6 extending downward from the upper end of the outer peripheral wall 535a3 and a lower end of the rib 535a6 to the end of the outer peripheral wall 535a3 on the game board 50 side. An extending rib 535a7 is provided upright. The game ball that has entered the starting prize-winning device 535 has a space formed between the ribs 535a6 formed on the left and right sides, the inner wall of the outer peripheral wall 535a5, and the front surface 51 of the game board 50. After being guided down to the bottom surface of the internal space, it is guided to the through hole of the game board 50 communicating with the discharge path by the bottom surface of the internal space and the ribs 535a7 formed on both the left and right sides.

  That is, the ball path of the start winning device 535 is a through-hole of the game board 50 through which the game ball that has passed between the pair of game nails Q4 and Q5 communicates with the discharge path as described above in the internal space of the main body 535a. It is a route guided to. Each of the ribs 535a6 and 535a7 formed on the left and right sides functions to form the outer edge of the ball passage and also functions to rectify the game ball passing through the ball passage.

  The upper end of the ball passage, that is, the opening at the boundary position where the game ball is surely guided to the discharge path after the game ball passes between the pair of game nails Q4 and Q5 is the start winning opening 525. The start winning port 525 is a ball opening that functions in the same manner as the start winning port 25 of the first embodiment. That is, the start winning port 525 is a ball opening through which a lottery such as a big hit is performed and a prize ball is paid out as a bonus when a game ball enters (passes).

  The nail cover portion 535b is a portion that functions as a nail cover that surrounds (covers) each head 102 of the pair of game nails Q4 and Q5 provided above the start winning device 535. Hereinafter, for convenience, the nail cover portion 535b surrounding the periphery of the head 102 of the game nail Q4 will be referred to as a nail cover portion 535bA, and the nail cover portion 535b surrounding the periphery of the head 102 of the game nail Q5 will be referred to as a nail cover. May be referred to as a portion 535bB.

  A nail cover portion 535bA surrounding the periphery of the head 102 of the game nail Q4 is connected to the upper end on the left end side of the outer peripheral wall 535a3 on the front surface side of the main body portion 535a. On the other hand, the nail cover part 535bB surrounding the periphery of the head 102 of the game nail Q5 is connected to the upper end on the right end side of the outer peripheral wall 535a3 on the front surface side of the main body part 535a. The front side of the nail cover part 535b (535bA, 535bB) is flush with the front surface of the outer peripheral wall 535a3 on the front side of the main body part 535a, for example, as shown in FIG. 8B.

  Each of the back surfaces of the nail cover portions 535bA and 535bB (the surface facing the game board 50 in the attached state) is opened in a circular shape slightly larger than the maximum outer diameter of the head 102 of the game nail Q4 or the game nail Q5. A receiving portion 535b1 is formed that is recessed to a depth that allows the head 102 to be received from the front. Therefore, in a state where the start winning device 535 is attached to the game board 50 with the screws 501 (that is, fixed), each of the nail cover portions 535bA and 535bB has the storage portions 535b1 of the game nail Q4 or the game nail Q5. The periphery of the head 102 (more specifically, the front side of the head 102 and the direction side intersecting the central axis of the shaft portion 101A in the head 102) is enclosed.

  Since the nail cover portion 535b (535bA, 535bB) is integrated with the start winning device 535 fixed to the game board 50, the nail cover portion 535b allows the nail cover portion 535b to surround the heads 102 of the game nails Q4 and Q5, in particular. Since the peripheral direction (hereinafter referred to as “around the axis center”) of the central axis of the shaft portion 101A of each head 102 which is the end portion on the front side of the front surface 51 in the game nails Q4 and Q5 is surrounded, The movement of the heads 102 of the nails Q4 and Q5 in any direction around the axis center can be restricted and restricted within a certain range. Therefore, even if an improper load is applied to the game nails Q4 and Q5 surrounded by the nail cover portion 535b to bend the game nails Q4 and Q5, the game nails Q4 and Q5 maintain the original standing state. can do.

  In particular, since the pair of game nails Q4 and Q5 are game nails that function as entrances to the start winning opening 525, the game nail Q4 and the game nails are advantageous in order to make ball entry (entry) into the start winning opening 525 advantageous. There is a high possibility of fraudulent attempts to widen the interval with Q5. In contrast, by enclosing the game nails Q4 and Q5 with the nail cover portion 535b, the distance between the game nail Q4 and the game nail Q5 (that is, the passing direction of the game ball passing between the game nail Q4 and the game nail Q5) It is difficult to widen the length in the direction orthogonal to. Accordingly, it is possible to suppress an illegal act of widening the distance between the pair of game nails Q4 and Q5 so that the entry (entrance) to the start winning opening 525 is facilitated. Similarly, it is difficult to narrow (close) the gap between the pair of game nails Q4 and Q5.

  Further, since the nail cover portions 535bA and 535bB are both connected to the main body portion 535a, it is impossible to change the interval between the nail cover portion 535bA and the nail cover portion 535bB. Therefore, it is difficult to widen the distance between the pair of game nails Q4 and Q5 in which the periphery of the head 102 is surrounded by the accommodating portions 535b1 of the nail cover portions 535bA and 535bB. Therefore, it is possible to suppress an illegal act of widening the distance between the pair of game nails Q4 and Q5 so as to facilitate the entry (entrance) to the start winning opening 525. Similarly, it is difficult to narrow (close) the gap between the pair of game nails Q4 and Q5.

  In the nail cover portions 535bA and 535bB, as shown in FIG. 8A, the upper edge portion 535b2 on the upper side in the front view of the gaming machine is configured in a substantially semicircular arc shape. More specifically, the upper edge portion 535b2 is formed in an arc shape of a substantially semicircular portion in a circle concentric with the accommodating portion 535b1 opened in a circular shape. That is, the upper edge portion 535b2 has a diameter larger than the maximum outer diameter of the head 102, centered on a position that substantially coincides with the axial center of the shaft portion 101A in the game nails Q4 and Q5 accommodated in the accommodating portion 535b1. It is comprised by the circular arc shape of the substantially semicircle part in a circle | round | yen.

  As described above, the upper edge 535b2 of the nail cover portion 535b (535bA, 535bB) has a diameter larger than the maximum outer diameter of the head 102 of the game nail Q4, Q5, but the axial center of the game nail Q4, Q5 Since the arc shape of the substantially semicircular portion of the circle centered on the position substantially coincident with the game nail Q4, Q5 flows down between the game plate 50 and the glass plate 11 when the game nail Q4, Q5 is surrounded by the nail cover portion 535b. The flow-down behavior of the game ball can resemble the flow-down behavior when the game nails Q4, Q5 are not surrounded by the nail cover portion 535b and the head 102 is exposed. Therefore, even when the nail cover portion 535b is attached to the game nails Q4 and Q5, it is possible to suppress the uncomfortable feeling that the player feels regarding the flow-down behavior of the game balls to a preferable level.

  Further, since the accommodating portion 535b1 is formed larger than the head 102 of the game nails Q4 and Q5, the game ball comes into contact with the contact portion 114 of the game nails Q4 and Q5, and the game nails Q4 and Q5 are When vibrated, the head 102 can be displaced in the housing portion 535b1. Therefore, even if the nail cover portion 535b is provided, it is possible to resemble the flow-down behavior when the game nails Q4 and Q5 are not surrounded by the nail cover portion 535b and the head 102 is exposed.

  In the example shown in FIG. 8A, the upper edge portion 535b2 has a substantially semicircular arc shape in a circle centered at a position substantially coincident with the axial centers of the game nails Q4 and Q5. The size of the game balls flowing down between the game plate 50 and the glass plate 11 when the game nails Q4 and Q5 are surrounded by the nail cover portion 535b, and the game nails Q4 and Q5 by the nail cover portion 535b. An arc smaller than a semicircle (for example, an arc with a central angle of 120 degrees) can be used as long as the similarity to the flow behavior when exposed without being surrounded is maintained at a predetermined level. It may be an arc larger than a circle (for example, an arc having a central angle of 270 degrees). Note that the upper edge portion 535b2 is in contact with a game ball flowing down from the upstream side, and therefore the upper edge portion 535b2 is preferably a semicircle or more arc.

  Further, the upper edge portion 535b2 is not limited to a circular arc centered on a position substantially coinciding with the axial centers of the game nails Q4 and Q5, but the front side of the gaming machine with respect to the axial centers of the game nails Q4 and Q5. It is good also as a circular arc of the circle centering on the position eccentrically on the upper side or the lower side in view. From the viewpoint of resembling the flow-down behavior of the game ball, the upper edge portion 535b2 is preferably a circular arc centered at a position substantially coinciding with the axial centers of the game nails Q4 and Q5. Further, the upper edge portion 535b2 is not limited to a circular arc that is symmetric with respect to a virtual line segment in the vertical direction in the front view of the gaming machine passing through the axial centers of the game nails Q4 and Q5. An arc asymmetric with respect to a virtual line segment may be used.

  Here, the operation and effect of the pachinko machine 10 to which the start winning device 535 of the third embodiment described above is attached will be described.

  According to the pachinko machine 10 of the third embodiment, the outer sides of the game nails Q4 and Q5 around the axial center of the head 102 are integrated with the start winning device 535 fixed to the game board 50. (535bA, 535bB) because the game nail Q4, Q5 is surrounded by the storage portion 535b1 of the game nail Q4, Q5, even if an improper load is applied from any direction around the axis center to bend the game nail Q4, Q5 The standing state can be maintained. As a result, for example, it becomes difficult to widen the gap between the game nail Q4 and the game nail Q5. Therefore, the distance between the pair of game nails Q4 and Q5 is set to facilitate entry into the start winning opening 525. Can suppress spreading fraud.

  Further, the nail cover portion 535 b is connected to the main body portion 535 a fixed to the game board 50 by screws 501. Therefore, the nail cover portion 535b (535bA, 535bB) is indirectly fixed to the game board 50 via the main body portion 535a that supports the nail cover portion 535b, so that the nail cover portion 535b (535bA, 535bB) is attached to the game nails Q4, Q5. Can be held. As a result, the occurrence of an event such as the nail cover portion 535b being accidentally detached or the attachment position with respect to the game nails Q4, Q5 is suppressed, so that the game nails Q4, Q5 are prevented from being bent in an unintended direction. it can.

  Further, since the nail cover portion 535b covers the front side corresponding to the player side with respect to the head 102 as the front end portion of the game nails Q4, Q5, the front end of the game nail as viewed from the player side. The part is covered with the nail cover 535 part b, and it is possible to recognize that it is difficult to improperly apply a force to the front end part of a person trying to perform an illegal act.

  In the above description according to the third embodiment, the nail cover portion 535b integrated with the start winning device 535 is used as a nail cover surrounding the front end portions (more specifically, the head portion 102) of the game nails Q4 and Q5. Was illustrated. That is, the above-exemplified nail cover portion 535b is attached to the game nails Q4 and Q5 by being supported by the main body portion 535a fixed to the game board 50 by the screws 501.

When the heads 102 of the game nails Q4 and Q5 are accommodated in the cover portions 550aA and 550aB, the attachment of the nail cover 550 to the game nails Q4 and Q5 is completed.

  In a state where the nail cover 550 is attached to the game nails Q4 and Q5, each of the cover portions 550aA and 550aB has a housing portion 550a1 around the game nail Q4 or the head 102 of the game nail Q5 (more specifically, , The front side of the head 102 and the direction side intersecting the central axis of the shaft portion 101A in the head 102).

  Since the cover portions 550aA and 550aB are connected by the connecting portion 550b, it is difficult to widen the distance between the pair of game nails Q4 and Q5 whose head 102 is surrounded by the accommodating portion 550a1. Therefore, it is possible to suppress an illegal act of widening the distance between the pair of game nails Q4 and Q5 so as to facilitate the entry (entrance) to the start winning opening 525. Similarly, it is difficult to narrow (close) the gap between the pair of game nails Q4 and Q5.

  As shown in FIG. 9A, the cover portion 550a (550aA, 550aB) of the nail cover 550 is substantially the same as the above-exemplified nail cover portion 535b. It is constructed in a semicircular arc shape. More specifically, the upper edge portion 550a3 is configured in an arc shape of a substantially semicircular portion in a circle concentric with the accommodating portion 550a1 opened in a circular shape. As a result, when the game nails Q4 and Q5 are surrounded by the nail cover 550, the flow behavior of the game ball flowing down between the game board 50 and the glass plate 11 is described. The game nails Q4 and Q5 are surrounded by the nail cover 550. It can resemble the flow behavior when it is exposed. Therefore, even when the nail cover 550 is attached to the game nails Q4 and Q5, the uncomfortable feeling that the player feels regarding the flow-down behavior of the game ball can be suppressed to a preferable level.

  According to the above-described nail cover 550, the mounting state with respect to the game nails Q4 and Q5 can be maintained independently, so that the nail cover 550 is not considered without considering the presence or absence of a support member such as the main body 535a for supporting the nail cover. Can be attached to various game nails erected in the game area 21.

  In addition, it is good also as a structure which fixes the position of the nail cover 550 with respect to the glass plate 11 by providing the adhesiveness or adhesive layer with respect to the glass plate 11 in the front side of the nail cover 550, and passing through the said layer.

  As described above, the periphery of each head 102 of the game nails Q4 and Q5, in particular, the axis center of each head 102 which is the end portion on the front side of the front surface 51 in the game nails Q4 and Q5 is surrounded. When the position of the nail cover 550 with respect to the glass plate 11 is fixed, the movement of each head 102 of the game nails Q4 and Q5 in any direction around the axis center can be restricted.

  Thereby, even if an improper load is applied to the game nails Q4 and Q5 surrounded by the nail cover portion 535b in order to bend the game nails Q4 and Q5, the game nails Q4 and Q5 remain in the initial standing state. Can be held. Therefore, the nail cover 550 that can fix the position of the nail cover 550 with respect to the glass plate 11 is attached to a plurality of game nails arranged in a row to guide the game ball in a predetermined direction, so that the game nail is bent and the game ball It is possible to suppress fraudulent acts that illegally change the guidance direction.

  For example, a plurality of game nails (so-called guide nails) for guiding a game ball to the start winning opening 525 may be arranged upward or downward (that is, the plurality of these nails so that entry into the start winning opening 525 is advantageous). It is likely to be an object that is illegally bent in a direction intersecting the guidance direction of the game ball by the arrangement of the game nails. On the other hand, by enclosing the plurality of game nails with the nail cover 550, it becomes difficult to bend the game nails upward or downward, so that it is easy to enter (enter) the start winning opening 525. In addition, illegal acts that illegally change the guidance direction of the game ball can be suppressed.

  The nail cover 550 shown in FIG. 9 has two cover portions 550a (550aA and 550aB) connected to each other by a connecting portion 550b, but has three or more cover portions 550a and adjacent cover portions. 550a may be connected by a connecting portion 550b. That is, the nail cover 550 may be configured to be able to surround three or more game nails. Further, when the nail cover 550 is fixed to the glass plate 11 or the game board 50, it may be configured to have only one cover portion 550a and surround one game nail.

<Fourth embodiment>
Next, a fourth embodiment will be described with reference mainly to FIGS. 10 and 11. The pachinko machine 10 according to the present embodiment also surrounds the periphery of the front end portion of each game nail with a nail cover with respect to the pair of game nails functioning as the entrance of the start winning opening, as in the third embodiment described above. Thus, unauthorized bending of the pair of game nails can be suppressed. In the following description, the same components as those in the first to third embodiments are denoted by the same reference numerals, description thereof is omitted, and portions different from the above embodiments are described.

  FIG. 10A is a front view of the start winning device 635, and FIG. 10B is a cross-sectional view of the start winning device 635 along the line LL in FIG. 10A. FIG. 10C is a cross-sectional view of the start winning device 635 along the line MM in FIG. In FIG. 10, a pair of game nails Q6 and Q7 which are provided above the start winning device 635 and function as the entrance of the start winning port 625 are shown together.

  In the example shown in FIG. 10, the pair of game nails Q6 and Q7 is the game nail 100A described above. The game nails Q6 and Q7 are not limited to the game nail 100A but may be any of the game nails 100B to 100D. Further, both the game nails Q6 and Q7 may not be the same shape game nails.

  The start winning device 635 is a resin winning device in which a start winning port 625 is formed. The start winning device 635 is configured to be transparent so that at least the front side of the housing portion 635c1 can visually recognize the game nails Q6 and Q7. The front side of the accommodating portion 635c1 may be translucent.

  The start winning device 635 includes a plate-like front plate portion 635a provided on the front side in the front view of the gaming machine, a front plate support portion 635b that supports the front plate portion 635a, and an upper side of the front plate portion 635a in the front view of the gaming machine. , And a nail cover portion 635c that is provided continuously.

  An attachment portion 635b1 for attaching the front plate support portion 635b to the game board 50 is provided on the outer peripheral wall of the front plate support portion 635b. In the example shown in FIG. 10, the attachment portion 635b1 is provided at each of three locations of the outer peripheral wall 635b2 on the left and right sides of the front plate support portion 635b and the outer peripheral wall 635b3 on the bottom side in the front view of the gaming machine. The attachment portion 635b1 has an insertion port through which the screw 601 can be inserted. The start winning device 635 is attached to the game board 50 by fixing the front board support part 635b to the game board 50 with a screw 601 inserted through the insertion port of the attachment part 635b1.

  An accommodation space 635b5 for accommodating the front plate portion 635a is formed on the inner side (the side facing the game board 50) of the front outer peripheral wall 635b4 in the front view of the gaming machine in the front plate support portion 635b. A space 635b6 surrounded by the front plate portion 635a, the outer peripheral wall 635b2, and the outer peripheral wall 635b3 is formed on the rear side of the accommodation space 635b5 in the front view of the gaming machine. Part of the space 635b6 is a discharge path (see FIG. 5) formed on the back side of the game board 50 (the surface that is the back side of the front surface 51) of the game ball that has entered the start winning device 635 from the upper opening in the front view of the gaming machine. It functions as a ball passage that guides to (not shown).

  More specifically, each inner wall of the left and right outer peripheral walls 635b2 has a rib 635b7 extending downward from the upper end of the outer peripheral wall 635b2 and a lower end of the rib 635b7 to the end of the outer peripheral wall 635b2 on the game board 50 side. An extending rib 635b8 is provided upright.

  On the other hand, on the back surface of the front plate portion 635a (that is, the surface facing the game board 50 in the state of being accommodated in the accommodation space 635b5), a rib 635a1 extending in the vertical direction is also erected, and the front plate portion 635a In the storage space 635b5, the game ball that has entered the start winning device 635 has the ribs 635b7 formed on the left and right sides, the rib 635a1 formed on the back surface of the front plate portion 635a, and the game board. After being guided down to the inner wall of the outer peripheral wall 635b3 (that is, the bottom surface of the space 635b6) by the space formed between the front surface 51 and the front surface 51, the ribs 635b8 formed on the left and right sides lead to the discharge path. The game board 50 is guided to the through hole.

  That is, the ball path of the start winning device 635 is guided in the space 635b6 to the through hole of the game board 50 through which the game ball passing between the pair of game nails Q6 and Q7 communicates with the discharge path as described above. It is a route. The ribs 635b7 and 635b8 formed on the left and right sides and the rib 635a1 formed on the back surface of the front plate portion 635a serve to form an outer edge of the ball path and play a game ball passing through the ball path. Serves the function of rectifying.

  The upper end of the ball passage, that is, the opening at the boundary position where the game ball is always guided to the discharge path after the game ball passes between the pair of game nails Q6 and Q7 becomes the start winning opening 625. The start winning port 625 is a ball opening that functions in the same manner as the start winning port 25 of the first embodiment. In other words, the start winning opening 625 is a winning opening through which a lottery such as a big hit is performed and a prize ball is paid out as a bonus when a game ball enters (passes).

  The front plate portion 635a is inserted into the accommodation space 635b5 from an upper open portion in the front view of the gaming machine, and the nail cover portion 635c is accommodated in the accommodation space 635b5 in a state of protruding upward from the front plate support portion 635b. The front plate portion 635a accommodated in the accommodation space 635b5 is a game with respect to the front plate support portion 635b until the relative position with respect to the front plate support portion 635b is finally fixed when the pachinko machine 10 is manufactured. It can be moved upward or downward in the machine front view, whereby the relative position to the front plate support 635b can be changed. Although details will be described later, the pachinko machine 10 of the present embodiment changes a relative position of the front plate portion 635a with respect to the front plate support portion 635b, and thereby functions as a pair of game nails Q6 and Q7 that function as the entrance of the start winning opening 625. Can be positioned at a suitable position.

  Between the accommodation space 635b5 and the space 635b6, a partition wall 635b9 that partitions these spaces is erected from the inner side of the outer peripheral wall 635b3 (that is, the bottom side of the accommodation space 635b5 and the space 635b6). The partition wall 635b9 extends from the left outer peripheral wall 635b2 at a portion from the bottom of the accommodation space 635b5 and the space 635b6 to a predetermined height set for the upward or downward movement of the front plate portion 635a relative to the front plate support portion 635b. It extends continuously to the right outer peripheral wall 635b2, and above it, the portion connected to the left outer peripheral wall 635b2 and the portion connected to the right outer peripheral wall 635b2 are formed in a shape separated at the center. .

  An engaging portion 635b10 having a sawtooth cross section is formed on the upper end side of the partition wall 635b9 that faces the back surface side of the front plate portion 635a. On the other hand, on the back surface of the front plate portion 635a, an engaging portion 635a2 having a sawtooth cross section that is a pair of engaging portions 635b10 is formed at a position corresponding to the engaging portion 635b10.

  In a state where the front plate portion 635a is accommodated in the accommodation space 635b5, the engagement portion 635a2 of the front plate portion 635a is engaged with the engagement portion 635b10 of the partition wall 635b9. Therefore, when a suitable position of the front plate portion 635a is determined by changing the relative position with respect to the front plate support portion 635b during the manufacture of the pachinko machine 10, the position of the front plate portion 635a is finally fixed thereafter. In the meantime, the position of the suitable front plate portion 635a can be temporarily held by the engagement between the engaging portion 635a2 and the engaging portion 635b10. Accordingly, it is possible to prevent troubles such as continuing to hold the front plate portion 635a with the operator's hand at a suitable position.

  A through hole 635b11 that communicates with the accommodation space 635b5 is formed in the outer peripheral wall 635b4 of the front plate support portion 635b at a position slightly above the bottom surface of the accommodation space 635b5 that accommodates the front plate portion 635a. At the time of manufacturing the pachinko machine 10, when the relative position of the front plate portion 635a with respect to the front plate support portion 635b is optimized, a curable resin such as epoxy resin is injected from the through hole 635b11, and the lower side of the accommodation space 635b5 is injected. Of the space surrounded by the outer peripheral walls 635b2, 635b3, 635b4 and the partition wall 635b9, the space below the lower end of the front plate portion 635a is filled with resin, and the front plate portion 635a and the outer peripheral wall 635b4 surrounding the periphery thereof, etc. By allowing the resin to enter and harden the boundary portions with the respective walls, the position of the optimized front plate portion 635a can be finally fixed.

  The nail cover portion 635c is a portion that functions as a nail cover that surrounds (covers) each head 102 of the pair of game nails Q6 and Q7 provided above the start winning device 635. Hereinafter, for convenience, the nail cover portion 635c covering the periphery of the head 102 of the game nail Q6 will be referred to as a nail cover portion 635cA, and the nail cover portion 635c covering the periphery of the head 102 of the game nail Q7 will be referred to as a nail cover. May be referred to as portion 635cB.

  A nail cover portion 635cA that covers the periphery of the head 102 of the game nail Q6 is connected to the upper end on the left end side of the front plate portion 635a. On the other hand, a nail cover portion 635cB that covers the periphery of the head 102 of the game nail Q7 is connected to the upper end on the right end side of the front plate portion 635a. The front side of the nail cover portion 635c (635cA, 635cB) is flush with the front surface of the front plate portion 635a as shown in FIG. 10B, for example.

  As shown in FIG. 10A, the nail cover portion 635c (635cA, 635cB) is substantially the same as the upper edge portion 535b2 of the third embodiment in the upper edge portion 635c2 on the upper side in the gaming machine front view. It is constructed in a semicircular arc shape. Thereby, similarly to the above-described nail cover portion 535b (535bA, 535bB) of the third embodiment, even when the nail cover portion 635c is attached to the game nails Q6, Q7, the player regarding the flow-down behavior of the game ball Can be suppressed to a desirable level.

  On the back surfaces of the nail cover portions 635cA and 635cB (surfaces facing the game board 50 in the attached state), there are formed storage portions 635c1 that are recessed to accommodate the head 102 of the game nail Q6 or the game nail Q7. Yes.

  More specifically, the opening on the back surface side of the nail cover portion 635c (635cA, 635cB) in the accommodating portion 635c1 is gradually narrowed from the upper side to the lower side (that is, the amount of change in the horizontal direction with respect to the unit length in the vertical direction). However, the lower end is configured to have a width that is slightly larger than the maximum outer diameter of the head 102 of the game nail Q6 or the game nail Q7. Moreover, the accommodating part 635c1 is comprised by the depth which can accommodate the head 102 of the game nail Q6 or the game nail Q7 from the front.

  The upper side of the accommodating portion 635c1 is open. Therefore, after the start winning device 635 is attached to the game board 50 with the screw 601, the front plate portion 635a is slid upward, so that the heads 102 of the game nails Q6 and Q7 are respectively corresponding to the corresponding nail cover portions 635c. (635cA, 635cB) can be accommodated in the accommodating portion 635c1.

  Therefore, in a state where the start winning device 635 is attached to the game board 50 with the screws 601 (that is, fixed), each of the nail cover portions 635cA and 635cB has the storage portions 635c1 of the game nail Q6 or the game nail Q7. The periphery of the head 102 (more specifically, the front side of the head 102 and the left and right sides and the lower side in the direction intersecting the central axis of the shaft portion 101A in the head 102) is enclosed. As described above, since the periphery of the head 102 of the game nail Q6 or the game nail Q7 is covered by the inner wall of the housing portion 635c1, it is difficult to perform an illegal act of bending the game nail Q6, Q7 because the inner wall becomes an obstacle. it can.

  Of the nail cover portion 635c, the housing portion 635c1 of the nail cover portion 635cA for the game nail Q6 is such that the head 102 of the game nail Q6 is attached to the front of the gaming machine when the start winning device 635 is attached to the game board 50. From the upper right to the lower left in view, it is designed to be close to or in contact with the side of the inner wall Z1 extending with an inclination such that the amount of change in the left-right direction relative to the unit length in the direction of gravity is sufficiently shorter than the unit length. Hereinafter, “inclination of the inner wall Z1” indicates an inclination of the longitudinal direction of the inner wall Z1 with respect to the direction of gravity. That is, in the present embodiment, the inclination of the inner wall Z1 indicates “an inclination extending (extending) from the upper right to the lower left in the front view of the gaming machine”. The magnitude of the inclination of the inner wall Z1 is “the magnitude of the inclination so that the amount of change in the left-right direction with respect to the unit length in the direction of gravity is sufficiently shorter than the unit length”. The “inclination magnitude” may be 20 degrees or less, preferably 10 degrees or less, and more preferably 8 degrees or less.

  On the other hand, the housing portion 635c1 of the nail cover portion 635cB for the game nail Q6 is such that the head 102 of the game nail Q7 moves from the upper left to the lower right in the front view of the gaming machine when the start winning device 635 is attached to the game board 50. And the amount of change in the left-right direction with respect to the unit length in the gravitational direction is designed to be close to or in contact with the side of the inner wall Z2 extending with an inclination such that it is sufficiently shorter than the unit length. Hereinafter, “inclination of the inner wall Z2” indicates an inclination of the longitudinal direction of the inner wall Z2 with respect to the direction of gravity. That is, in the present embodiment, the inclination of the inner wall Z2 indicates “an inclination extending (extending) from the upper left to the lower right in the gaming machine front view”. The magnitude of the inclination of the inner wall Z2 is “the magnitude of the inclination such that the amount of change in the left-right direction relative to the unit length in the direction of gravity is sufficiently shorter than the unit length”.

  More specifically, each housing portion 635c1 of the nail cover portions 635cA and 635cB has the game nail Q6 or the nail Q6 when the front plate portion 635a is moved within a range where the engaging portion 635a2 and the engaging portion 635b10 are engaged. The head 102 of the game nail Q7 is designed to contact the inner wall Z1 or the inner wall Z2 at least in a part within the range. The pachinko machine 10 according to the present embodiment is configured so that the game nails Q6 and Q7 can be appropriately positioned by using the nail cover portion 635c designed as described above in the housing portion 635c1 at the time of manufacture. .

  Here, with reference to FIG. 11, the positioning of the game nails Q6 and Q7 using the nail cover portion 635c (635cA, 635cB) will be described. FIG. 11 is a cross-sectional view of the vicinity of the nail cover portion 635cA cut along a plane parallel to the game board 50. More specifically, FIG. 11A is a cross-sectional view when the position of the front plate portion 635a with respect to the front plate support portion 635b is at a predetermined position, and FIG. 11B shows the front plate portion 635a in FIG. It is sectional drawing when it is made to slide upwards from the state of (a).

  The inner wall Z1 of the accommodating portion 635c1 that accommodates the game nail Q6 is inclined from the upper right to the lower left in the front view of the gaming machine, so that the front plate portion is in a state where the game nail Q6 is in contact with the inner wall Z1. When the 635a is slid upward (that is, moved upward relative to the front plate support portion 635b fixed by the screw 601), the game nail Q6 is moved in the upper left direction in the front view of the gaming machine by the inner wall Z1. Pressed.

  The inclination of the inner wall Z1 is set such that the amount of change in the left-right direction with respect to the unit length in the direction of gravity is sufficiently shorter than the unit length. Is negligible, and the game nail Q6 is substantially pushed to the left. Below, the pressing direction of the game nail Q6 by the inner wall Z1 of the accommodating part 635c1 accompanying sliding the front board part 635a upward is demonstrated as the left direction which is a substantial pressing direction.

  That is, the front plate portion 635a is in a state where the head 102 of the game nail Q6 is in contact with the inner wall Z1 at a height H1 from the lower inner wall Z0 of the housing portion 635c1 (ie, the state shown in FIG. 11A). When the head 102 is slid upward from the inner wall Z0 and is in a state of being in contact with the inner wall Z1 at a height H2 (H1 <H2) (that is, the state shown in FIG. 11B), The nail Q6 is pressed leftward by the inner wall Z1.

  Similarly, the inner wall Z2 of the accommodating portion 635c1 that accommodates the game nail Q7 is inclined from the upper left to the lower right in the front view of the gaming machine, so that the front of the game nail Q7 is in contact with the inner wall Z2. When the plate portion 635a is slid upward, the game nail Q7 is pressed in the upper right direction when viewed from the front of the gaming machine by the inner wall Z2.

  The inclination of the inner wall Z2 is set so that the amount of change in the left-right direction relative to the unit length in the direction of gravity is sufficiently shorter than the unit length. Is negligible, and the game nail Q7 is substantially pushed rightward. Below, the pressing direction of the game nail Q7 by the inner wall Z2 of the accommodating part 635c1 accompanying sliding the front board part 635a upward is demonstrated as a right direction which is a substantial pressing direction.

  Therefore, according to the pachinko machine 10 of the present embodiment, in the state where the start winning device 635 is attached to the game board 50 with the screws 601, when the front plate portion 635a is slid upward, the game nail Q6 and the game nail Q7 Are pressed in the left direction and the right direction in the front view of the gaming machine, respectively, so that the game nail Q6 and the game nail Q7 can be moved in the left direction and the right direction, respectively. Thereby, the interval between the game nail Q6 and the game nail Q7 (more specifically, the interval between the contact portions 114 with which the game balls abut on each game nail Q6, Q7) can be increased.

  Therefore, when the pachinko machine 10 is manufactured, after the game nails Q6 and Q7 are struck against the game board 50, the interval between the game nails Q6 and Q7 is adjusted to a suitable width (that is, an interval within the design allowable range). can do. As described above, after the position of the front plate portion 635a is adjusted so that the gap between the game nails Q6 and Q7 has a suitable width, the front plate portion 635a is injected by injecting a curable resin from the through hole 635b11. Is finally fixed at a suitable position after adjustment. Thereby, after the space | interval of game nail Q6, Q7 is adjusted appropriately, the front board part 635a is moved, and it can suppress that the space | interval of game nail Q6, Q7 becomes an unsuitable width | variety by this.

  The front plate portion 635a is configured to be slidable upward, but at the lower end corresponding to the initial position, at least a part of the head 102 of the game nails Q6 and Q7 can be seen from the front side of the gaming machine. It is preferable to set the movable range as described above, and it is preferable to set so that the entire range can be seen. Accordingly, even when the start winning device 635 is attached to the game board 50, the front plate portion 635a is positioned at the lowermost end and the heads 102 of the game nails Q6 and Q7 are manually adjusted from the front side. Fine adjustment can be performed by sliding the plate portion 635a upward.

  Here, the operation and effect of the pachinko machine 10 to which the start winning device 635 of the fourth embodiment described above is attached will be described.

  According to the pachinko machine 10 of the fourth embodiment, the magnitude of the inclination of the inner walls Z1, Z2 in the accommodating portion 635c1 is such that the amount of change in the left-right direction with respect to the unit length in the gravity direction is sufficiently shorter than the unit length. Since the size is set, when the front plate portion 635a is slid upward, the game nails Q6 and Q7 are moved to the left and right, respectively. Therefore, the space between the game nails Q6 and Q7 can be widened by sliding the front plate portion 635a upward.

  In conventional pachinko machines, the position of the game nail may be displaced when it is attached to the game board. If the position of the game nail is displaced, the performance of the game machine may differ from the design value. . For example, when a position shift occurs in a pair of game nails that are provided above the start prize opening such as the start prize opening 625 and function as an entrance to the start prize opening, the distance between the pair of game nails is a design value. As a result, a situation may occur in which the entrance probability of the game ball entering (winning) the start winning opening differs from the design value.

  On the other hand, according to the pachinko machine 10 of the fourth embodiment, at the time of manufacture, the front plate portion 635a is slid upward (that is, the nail cover portion 635c is moved upward with respect to the game nails Q6, Q7), Thereby, by adjusting the interval between the game nails Q6 and Q7, the game nails Q6 and Q7 can be positioned so that the interval becomes a suitable width (that is, an interval within the design allowable range). Therefore, when the pachinko machine 10 is manufactured, the game nails Q6 and Q7, which have been mounted at intervals that do not match the design standard value (design median value), are positioned so as to approach the design standard value. Even when the machine 10 is manufactured, they can be shipped as pachinko machines having performance close to the design standard value.

  In addition, as a part of the start winning device 635, the front plate portion 635a is removed by performing final fixing at that position even after the relative position with respect to the front plate support portion 635b is suitably determined. You can leave without. Therefore, it is not necessary to remove the member used for positioning of the game nails Q6 and Q7 after the positioning, and it is possible to save time and effort required for the removal process and the removal process.

  Further, the front plate portion 635a can be slid upward or downward while the engaging portion 635a2 is guided by the engaging portion 635b10. As a result, the moving direction of the front plate portion 635a relative to the game nails Q6 and Q7 is regulated by the engaging portion 635a2 and the engaging portion 635b10. Therefore, the moving direction of the game nails Q6 and Q7 due to the sliding of the front plate portion 635a is constant. Can be done. Thereby, the versatility with respect to positioning of the game nails Q6 and Q7 can be enhanced.

  In addition, the inner wall of the accommodating portion 635c1 intersects the periphery of the head 102 of the game nails Q6 and Q7 (more specifically, the front side of the head 102 and the central axis of the shaft portion 101A in the head 102). Since it surrounds the left and right sides of the direction), it is possible to make it difficult to perform an illegal act of bending the game nails Q6 and Q7 because the inner wall becomes an obstacle. Thus, the nail cover portion 635c (635cA, 635cB) has both a function of suppressing an illegal bending action on the game nails Q6 and Q7 and a function of appropriately positioning the game nails Q6 and Q7.

  Further, the front plate portion 635a provided with the housing portion 635c1 is slid upward to house the heads 102 of the game nails Q6 and Q7 in the housing portion 635c1, so the heads 102 of the game nails Q6 and Q7 are accommodated. If the position is far from the design allowable range, the heads 102 of the game nails Q6 and Q7 are not accommodated in the accommodating portion 635c1 even if the sliding operation is performed, and the peripheral portions interfere with each other. For this reason, the front plate portion 635a cannot be slid until the design allowable range is reached, or a part of the front plate portion 635a interferes with the heads 102 of the game nails Q6 and Q7 due to the sliding operation. easy. Therefore, it is possible to easily detect that the heads 102 of the game nails Q6 and Q7 are out of the design allowable range by the sliding operation of the front plate portion 635a.

  In the above description according to the fourth embodiment, the game nail 100A is exemplified as the game nails Q6 and Q7. However, the game nail 100D is used so that the longitudinal direction of the grooves 115 and 116 is orthogonal to the direction to be bent. By attaching to the game board 50, the game nails Q6 and Q7 are easily bent by the press by the inner walls Z1 and Z2 of the housing part 635c1, and therefore the game nails Q6 and Q7 can be easily adjusted by sliding the front plate part 635a.

  The upper end of the ball passage, that is, the opening at the boundary position where the game ball is surely guided to the discharge path after the game ball passes between the pair of game nails Q8 and Q9 is the start winning opening 725. The start winning opening 725 is a ball opening that functions in the same manner as the start winning opening 25 of the first embodiment. That is, the start winning hole 725 is a ball opening through which a lottery such as a big hit is performed and a prize ball is paid out as a bonus when a game ball has entered (passed).

  The main body support portion 735b has a U-shaped cross-section with an open upper surface, and is attached so that the rear end side enters the game board 50 from the front surface 51 as shown in FIG. An attachment portion 735b1 for attaching the main body support portion 735b to the game board 50 is provided on the outer peripheral wall of the main body support portion 735b. In the example shown in FIG. 12, the attachment portion 735b1 is provided at each of three locations of the outer peripheral wall 735b2 on both the left and right sides of the main body support portion 735b and the outer peripheral wall 735b3 on the bottom side in the front view of the gaming machine. The attachment portion 735b1 has an insertion port through which the screw 701 can be inserted. The start winning device 735 is attached to the game board 50 by fixing the main body support part 735b to the game board 50 with a screw 701 inserted through the insertion port of the attachment part 735b1.

  An accommodation space for accommodating the main body 735a is formed inside the outer peripheral walls 735b2 and 735b3 of the main body support 735b. Therefore, the main body support portion 735b supports the main body portion 735a accommodated in the accommodation space from below.

  The main body support portion 735b is provided with a protruding portion 735b5 that protrudes inward from the inner wall of the outer peripheral wall 735b2 from the upper end of each outer peripheral wall 735b2 on both the left and right sides. The protrusion 735b5 serves as a stopper so that the main body 735a housed in the housing space does not fall off from the upper side.

  The main body portion 735a is inserted into the accommodation space from an open portion on the front side in a front view of the gaming machine, and the front plate 735a1 is accommodated in the accommodation space in a state of protruding forward from the main body support portion 735b. The rear end side of the main body 735 a housed in the housing space enters the game board 50 from the front surface 51. When the pachinko machine 10 is manufactured, the main body 735a accommodated in the accommodation space is in a front view of the gaming machine with respect to the main body support 735b until the relative position with respect to the main body support 735b is finally fixed. It can be moved in the forward or backward direction, whereby the relative position with respect to the main body support portion 735b can be changed.

  Although details will be described later, the pachinko machine 10 according to the present embodiment preferably includes a pair of game nails Q8 and Q9 that function as the entrance of the start winning opening 725 by changing the relative position of the main body 735a with respect to the main body support 735b.

  An engagement portion 735b6 having a sawtooth cross section is formed on the inner wall on the rear end side of the outer peripheral wall 735b3 on the bottom side of the main body support portion 735b. On the other hand, on the bottom wall 735a2 of the main body portion 735a, an engagement portion 735a8 having a sawtooth cross section that is a pair of the engagement portions 735b6 is formed at a position corresponding to the engagement portion 735b6.

  In a state where the main body portion 735a is accommodated in the accommodation space, the engaging portion 735a8 of the main body portion 735a is engaged with the engaging portion 735b6 of the main body support portion 735b. Therefore, when a suitable position of the main body part 735a is determined by changing the relative position with respect to the main body support part 735b at the time of manufacturing the pachinko machine 10, until the position of the main body part 735a is finally fixed thereafter. In the meantime, it is possible to temporarily hold the position of the main body portion 735a which is considered suitable by the engagement between the engaging portion 735a8 and the engaging portion 735b6. Thereby, it is possible to prevent troubles such as holding the main body 735a with the operator's hand at a suitable position.

  Through holes 735b7 penetrating from the upper surface to the lower surface of the protrusion 735b5 are formed in the protrusions 735b5 provided on the left and right outer peripheral walls 735b2 of the main body support 735b. Therefore, as shown in FIG. 12C, in the state where the main body 735a is accommodated in the accommodation space, the boundary portion between the side wall 735a3 and the outer peripheral wall 735b2 is exposed at the bottom facing the through hole 735b7 from the upper surface side. ing.

  Accordingly, when the relative position of the main body 735a with respect to the main body support 735b is optimized during the manufacture of the pachinko machine 10, a curable resin such as an epoxy resin is injected from the through hole 735b7, and the side wall 735a3 and the outer peripheral wall 735b2 are injected. In order to finally fix the position of the optimized main body portion 735a, the resin is infiltrated into the boundary portion and cured.

  The nail cover portion 735c is a portion that functions as a nail cover that surrounds (covers) the periphery of each head 102 of the pair of game nails Q8 and Q9 provided above the start winning device 735. Hereinafter, for convenience, the nail cover portion 735c covering the periphery of the head 102 of the game nail Q8 will be referred to as a nail cover portion 735cA, and the nail cover portion 735c covering the periphery of the head 102 of the game nail Q8 will be referred to as a nail cover. May be referred to as part 735cB.

  A nail cover portion 735cA that covers the periphery of the head 102 of the game nail Q8 is connected to the upper end on the left end side of the front plate 735a1 in the main body portion 735a. On the other hand, a nail cover portion 735cB that covers the periphery of the head 102 of the game nail Q9 is connected to the upper end on the right end side of the front plate 735a1. The front side of the nail cover portion 735c (735cA, 735cB) is flush with the front surface of the front plate 735a1, for example, as shown in FIG.

  As shown in FIG. 12A, the nail cover portion 735c (735cA, 735cB) has an edge portion 735c2 including an upper end concentric with the housing portion 735c1 having a circular cross section parallel to the game board 50. Consists of circular arc shape. The upper edge 535b2 of the third embodiment has a substantially semicircular arc shape, whereas the arc constituting the edge 735c2 is a semicircle or more, but the edge 735c2 has an upper edge. The same effect as that of the end portion 535b2 is obtained. That is, even when the nail cover portion 735c having the edge portion 735c2 is attached to the game nails Q8 and Q9, the uncomfortable feeling that the player feels regarding the flow-down behavior of the game ball can be suppressed to a preferable level. .

  On the back surfaces of the nail cover portions 735cA and 735cB (surfaces facing the game board 50 in the attached state), there are formed accommodating portions 735c1 that are recessed so as to accommodate the head 102 of the game nail Q8 or the game nail Q9. Yes. More specifically, the housing portion 735c1 is configured in a truncated cone shape having the bottom surface of the housing portion 735c1 as the top surface and the opening of the housing portion 735c1 as the bottom surface.

  Of the cross-sections passing through the center of the opening and the bottom surface of the housing portion 735c1, the straight line corresponding to the slope portion of the truncated cone is gently from the opening side of the housing portion 735c1 toward the bottom surface as shown in FIG. The shape is narrowed (that is, the amount of change in the direction orthogonal to the direction relative to the unit length from the opening side to the bottom surface of the housing portion 735c1 is shorter than the unit length). Moreover, the accommodating part 735c1 is comprised by the depth which can accommodate the head 102 of the game nail Q7 or the game nail Q8 from the front.

  By attaching the start winning device 735 to the game board 50 with the screws 701, the respective heads 102 of the game nails Q8 and Q9 are inserted from the openings of the accommodating portions 735c1 of the corresponding nail cover portions 735c (735cA and 735cB), respectively. Thereby, each head 102 can be accommodated in the accommodating part 735c1.

  Therefore, in a state where the start winning device 735 is attached (that is, fixed) to the game board 50 with the screws 701, the nail cover portions 735cA and 735cB are respectively provided with the respective storage portions 735c1 of the game nail Q8 or the game nail Q9. The periphery of the head 102 (more specifically, the front side of the head 102 and the direction side intersecting the central axis of the shaft portion 101A in the head 102) is enclosed. As described above, since the periphery of the head 102 of the game nail Q8 or the game nail Q9 is surrounded by the inner wall of the housing portion 735c1, it is difficult to perform an illegal act of bending the game nail Q8, Q9 because the inner wall becomes an obstacle. it can.

  Of the nail cover portion 735c, the housing portion 735c1 of the nail cover portion 735cA for the game nail Q8 is such that the head 102 of the game nail Q8 is attached to the front of the gaming machine when the start winning device 735 is attached to the game board 50. It is designed to be close to or in contact with the inner wall on the right side as viewed (that is, the side close to the paired game nail Q9).

  On the other hand, the housing portion 735c1 of the nail cover portion 735cB with respect to the game nail Q9 is such that the head 102 of the game nail Q9 is on the left side in the front view of the gaming machine (that is, the pair It is designed to be close to or in contact with the inner wall on the side close to the game nail Q8.

  More specifically, each of the receiving portions 735c1 of the nail cover portions 735cA and 735cB has the game nails Q8 and Q9 when the main body portion 735a is moved within a range where the engaging portion 735a8 and the engaging portion 735b6 are engaged. The head 102 is designed to contact the inner wall on the side close to the paired game nail at least in part within the range. The pachinko machine 10 according to the present embodiment is configured so that the game nails Q8 and Q9 can be appropriately positioned by using the nail cover portion 735c designed as described above in the housing portion 735c1 at the time of manufacture. .

  Here, with reference to FIG. 13, the positioning of the game nails Q8 and Q9 using the nail cover portion 735c (735cA, 735cB) will be described. FIG. 13 is an enlarged cross-sectional view of the vicinity of the nail cover portion 735cA in FIG. In FIG. 13, a nail cover part 735cA indicated by a solid line shows a case where the main body part 735a is in a predetermined position with respect to the main body support part 735b. On the other hand, the alternate long and two short dashes line indicates the position of the accommodating portion 735c1 when the main body portion 735a at the predetermined position is slid rearward.

  Since the housing portion 735c1 is configured in a truncated cone shape that narrows from the opening side of the housing portion 735c1 toward the bottom surface, the game nail Q8 is closer to the game nail Q9 on the inner wall of the housing portion 735c1 (right side in FIG. 13). When the main body 735a is slid rearward (that is, moved rearward relative to the main body support 735b fixed by the screw 701) in a state where the game nail Q8 is in contact with the game nail Q8, Q8 is pressed in the rear left direction in the front view of the gaming machine by the inner wall that comes into contact.

  At this time, as described above, the inner wall of the accommodating portion 735c1 has a shape that gradually narrows from the opening side toward the bottom surface. Therefore, the backward pressing is negligible, and the game nail Q8 is substantially Pressed in the left direction. Below, the pressing direction of the game nail Q8 by the inner wall of the accommodating part 735c1 accompanying sliding the main-body part 735a back is demonstrated as a left direction which is a substantial pressing direction. That is, when the main body portion 735a is slid rearward with the head 102 of the game nail Q8 in contact with the storage portion 735c1, the game nail Q8 has the storage portion 735c1 as shown in FIG. It is pressed leftward by the inner wall.

  Similarly, when the main body 735a is slid rearward with the game nail Q9 in contact with the inner wall of the housing portion 735c1 near the game nail Q8, the game nail Q9 It is pressed in the right rear direction in the front view of the gaming machine by the contacting inner wall. At this time, for the same reason as in the case of the game nail Q8 described above, the backward push is negligible, so the game nail Q9 is substantially pushed rightward. Below, the pressing direction of the game nail Q9 by the inner wall of the accommodating part 735c1 accompanying sliding the main-body part 735a back is demonstrated as a right direction which is a substantial pressing direction.

  Therefore, in the state where the start winning device 735 is attached to the game board 50 with the screw 701, when the main body 735a is slid rearward, the game nail Q8 and the game nail Q9 are respectively in the left direction in the gaming machine front view and Since it is pushed rightward, the game nail Q8 and the game nail Q9 can be moved in the left direction and the right direction, respectively. Thereby, the interval between the game nail Q8 and the game nail Q9 (more specifically, the interval between the contact portions 114 with which the game balls in the game nails Q8 and Q9 abut) can be increased.

  Therefore, when the pachinko machine 10 is manufactured, after the game nails Q8 and Q9 are struck to the game board 50, the interval between the game nails Q8 and Q9 is adjusted to a suitable width (that is, an interval within the design allowable range). can do. As described above, after the position of the main body portion 735a is adjusted so that the gap between the game nails Q8 and Q9 becomes a suitable width, the position of the main body portion 735a is injected by injecting a curable resin from the through hole 735b7. Is finally fixed at a suitable position after adjustment. Thereby, after the space | interval of game nail Q8, Q9 is adjusted appropriately, the main-body part 735a is moved, and it can suppress that the space | interval of game nail Q8, Q9 becomes an inappropriate width | variety by it.

  Here, the operation and effect of the pachinko machine 10 to which the start winning device 735 according to the fifth embodiment described above is attached will be described.

  According to the pachinko machine 10 of the fifth embodiment, since the accommodating portion 735c1 has a truncated cone shape that gradually narrows from the opening side toward the bottom surface, the main body portion 735a is slid rearward (that is, the game nail Q8, The nail cover portion 735c is moved rearward with respect to Q9), whereby the game nails Q8 and Q9 are moved to the left and right, respectively. Therefore, the space | interval of the game nails Q8 and Q9 can be expanded by sliding the main-body part 735a back.

  Therefore, at the time of manufacture, the main body 735a is slid rearward to adjust the interval between the game nails Q8 and Q9, so that the interval becomes a suitable width (that is, an interval within the design allowable range). Q8 and Q9 can be positioned. Therefore, when the pachinko machine 10 is manufactured, the game nails Q8 and Q9, which are mounted at intervals outside the design allowable range, are positioned so as to be within the design allowable range. It can be shipped as a pachinko machine with the above performance.

  In addition, the main body 735a remains as a part of the start winning device 735 even after the relative position with respect to the main body support 735b is suitably determined, by performing final fixing at that position without being removed. be able to. Therefore, it is not necessary to remove the member used for positioning of the game nails Q8 and Q9 after the positioning, and it is possible to save time and effort required for the removal process and the removal process.

  The main body 735a can be slid forward or backward while the engaging portion 735a8 is guided by the engaging portion 735b6. As a result, the moving direction of the main body 735a relative to the game nails Q8 and Q9 is regulated by the engaging portion 735a8 and the engaging portion 735b6. can do. Thereby, the versatility with respect to positioning of the game nails Q8 and Q9 can be improved.

  In addition, the inner wall of the accommodating portion 735c1 is around the head 102 of the game nail Q8 or the game nail Q9 (more specifically, the front side of the head 102 and the central axis of the shaft portion 101A of the head 102). Enclose the crossing direction side). Thus, the nail cover portion 735c (735cA, 735cB) has both a function of suppressing an illegal bending action on the game nails Q8, Q9 and a function of appropriately positioning the game nails Q8, Q9.

  Further, since the main body 735a is moved forward or backward in the front view of the gaming machine with respect to the main body support 735b, the relative position of the main body 735a with respect to the main body support 735b is any. First, since there is no change in the arrangement of the main body 735a (more specifically, the start winning device 735) on the game board 50 in the front view of the gaming machine, the overall appearance of the game board 50 does not change greatly, and the game It can suppress giving a strange feeling to a person. Therefore, it is possible to position the game nails Q8 and Q9 so that the performance is within the design allowable range without giving the player a sense of incongruity.

  In addition, since the main body portion 735a provided with the housing portion 735c1 is slid rearward to accommodate the heads 102 of the game nails Q8 and Q9 in the housing portion 635c1, the head portions 102 of the game nails Q8 and Q9 are accommodated. If the position is greatly deviated from the design allowable range, the head 102 of the game nails Q8 and Q9 is not accommodated in the accommodating portion 735c1 even if the sliding operation is performed, and the peripheral portion interferes. For this reason, the main body 735a cannot be slid until it reaches the design allowable range, or a part of the main body 735a easily interferes with the heads 102 of the game nails Q8 and Q9 due to the sliding operation. Therefore, it is possible to easily detect that the heads 102 of the game nails Q8 and Q9 are out of the design allowable range by the sliding operation of the main body 735a.

  In the above description according to the fifth embodiment, the game nail 100A is illustrated as the game nail Q8, Q9. However, the game nail 100D is used so that the longitudinal direction of the grooves 115, 116 is orthogonal to the direction to be bent. By attaching to the game board 50, the game nails Q8 and Q9 can be easily bent by the pressure applied by the inner wall of the housing portion 735c1, so that the game nails Q8 and Q9 can be easily adjusted by sliding the main body 735a.

  In addition, this invention is not restricted to the said embodiment, For example, you may deform | transform and implement as described below. In this case, each configuration described below may be applied to the above embodiment, or a plurality of configurations described below may be combined and applied to the above embodiment.

(2) Modified Examples of Spiral Part 112 and Stopping Part 113 In each of the above embodiments, the game nails 100A to 100D are the part for securing the holding force with respect to the game board 50, and the spiral part 112 and the stop part 113. However, a configuration including only one of the spiral portion 112 or the retaining portion 113 may be used. Further, the game nails 100 </ b> A to 100 </ b> D may be configured to include neither the spiral portion 112 nor the retaining portion 113.

  In each of the above embodiments, the shape shown in FIG. 3B is adopted as the retaining portion 113, but it has a shape that can enter the game board 50 and prevent the game nails 100A to 100D from moving in the removal direction. Any suitable shape can be employed. For example, the fixed shape is not continuous on the circumferential side like the retaining portion 113, and a plurality of spinous protrusions spaced apart on the circumferential direction side may be used as the retaining portion.

  (3) In each of the above embodiments, the partition portion between the game area 21 and the launch passage 31 is formed by the plurality of game nails 100A arranged, but the partition portion may be the game area 21 or the launch passage 31.

Good. In particular, when the surface including the straight portion 101Ba1 is arranged facing the launch passage 31, the undulation on the launch passage 31 side is reduced, so that the game ball launched from the launch device is preferably guided. It is possible to enter the game area 21.

(4) Modified example of game nail attached near the exit of the launch passage 31 In each of the above embodiments, the game nail 100C is placed near the exit of the launch passage 31 and the apex 101Ca1 of the first shaft portion 101Ca faces upward. It is set as the structure which suppresses the fraud using the game ball which attached the thread | yarn.

  As a game nail attached to the vicinity of the exit of the launch passage 31 for the purpose of suppressing the illegal act, a taper groove such as a V-shape extends from the opening toward the inside of the shaft. It is good also as a structure using the game nail formed in the contact part. When such a game nail is attached, for example, in the vicinity of the exit of the launch passage 31 so that the opening of the groove portion faces upward (for example, slightly upward on the opposite side of the launch passage 31), the game ball to which the thread is attached is It is easy to hang on the game nail in a state where the thread enters the back of the groove. And since the bottom of the groove part is formed in a tapered shape such as a V-shape, the yarn that has entered the groove part enters the bottom of the groove part as the yarn is moved. When the yarn is pulled or loosened in such a state, the yarn is rubbed by the side wall and the bottom portion of the groove, and the yarn can be cut eventually. It is preferable that such a groove portion draws a curve from the opening side to the bottom in the cross section in the axial direction. For example, in the state where the game nail is attached so that the opening of the groove portion faces slightly upward on the opposite side of the launch passage 31, the cross section of the groove portion in the axial direction draws a curve that curves gently upward from the opening portion. In this case, it is possible to make it difficult for the yarn that has entered the groove to be removed by manipulating the yarn.

  (5) In each of the above embodiments, as the game nails 100B and 100C, the case where the partial cross-sectional shapes of the shaft portions 101B and 101C are non-circular is illustrated. Specifically, a game nail 100B in which a cross-sectional shape of a part of the shaft part 101B (first shaft part 101Ba) is a semicircular shape including a linear part 101Ba1 and an arc part 101Ba2 and a part of the shaft part 101C (first An example of the game nail 100C is shown in which the cross-sectional shape of the one shaft portion 101Ca) is a semicircular arc or less and a straight line extending from each of the both ends 101Ca2 and 101Ca3.

  The cross-sectional shape of the shaft portion may be a non-circular shape other than those described above. For example, the shaft portion is connected to the first outer surface having a cross section of the shaft portion (that is, a cross section perpendicular to the axial direction of the shaft portion) formed in an arc having a first curvature, and the first outer surface. The cross section may include an arc having a second curvature smaller than the first curvature, a straight line, or a second outer surface formed in a shape having at least one bent corner. Since the cross-sectional shape of the shaft portion including the contact portion is non-circular, the game ball that contacts the shaft portion rebounds characteristically according to the contact direction, so that the game ball rebounds by the game nail It is possible to improve the interest in the behavior.

  For example, like the first shaft portion 101Ba of the game nail 100B, the cross-sectional shape is not limited to the combination of the straight portion 101Ba1 and the semicircular arc portion 101Ba2, but an arc portion smaller or larger than the semicircle. Further, it may be configured by combining a straight line connecting both ends of the arc part and an arc having a smaller curvature than the arc part.

  At this time, the game nail in which the surface including the straight portion 101Ba1 in the shaft portion 101B of the game nail 100B is replaced with a surface having a circular arc close to a straight line in the cross section (that is, an arc having a smaller curvature than the arc portion 101Ba2) You may employ | adopt as a game nail attached to the vicinity of the partition part which partitions off between 21 and the launching passage 31. FIG.

  Further, like the first shaft portion 101Ca of the game nail 100C, the cross-sectional shape is not limited to a configuration having one bent corner portion by straight lines extending from both ends 101Ca2 and 101Ca3 of the arc, but from the one end 101Ca2 of the arc to the other. It is good also as a structure which has the corner | angular part 2 or more bent between end 101Ca3. Further, as in the first shaft portion 101Ca, the arc portion in the cross-sectional shape is not limited to a semicircle or less arc, but may be a semicircle or more arc. In other words, the bent corner included in the cross-sectional shape is not limited to an acute angle and may be an obtuse angle.

(6) Modified Example of Nail Unit 200 In each of the above embodiments, the nail unit 200 is described as having two game nails 100D connected by the connecting portion 201. However, there are two game nails 100D constituting the nail unit 200. It is not limited to books. That is, the structure by which 3 or more game nails 100D are connected by a connection part may be sufficient. Even when three or more game nails 100D are connected to the connecting portion, a protrusion similar to the protrusion 201a may be formed between the two game nails 100D.

  In each of the above embodiments, in the nail unit 200, the game nail 100D having the groove portions 115 and 116 formed in a direction orthogonal to the axial direction of the shaft portion 101D is connected to the extending direction of the groove portions 115 and 116 and the connecting portion 201. Although it was set as the structure attached so that a longitudinal direction may correspond, the structure by which the game nail 100D is attached so that the extending direction of the groove parts 115 and 116 may be substantially orthogonal to the longitudinal direction of the connection part 201 may be sufficient. . According to such a configuration, the strength with respect to the direction orthogonal to the longitudinal direction of the connecting portion 201 can be increased. Therefore, in the nail unit in which the game ball passes between the two game nails connected by the connecting portion, like the nail unit 200 attached above the start winning opening 25, the game nails constituting the nail unit are It is possible to suppress damage by the game ball passing between the game nails.

  On the other hand, according to the configuration of the modified example, the strength with respect to the direction along the longitudinal direction of the connecting portion 201 is reduced, so that the game nail is easily damaged by a load that widens the interval between the game nails connected by the connecting portion. Become. Conventionally, a pair of game nails that are attached above a ball entrance (for example, a start prize port 25) that grants benefits such as prize balls or lottery by passing game balls, Prone to fraudulent acts that facilitate the passage of game balls. On the other hand, like a nail unit 200 attached above the start winning opening 25, a pair of game nails functioning as entrances to the entrance for giving a prize such as a prize ball or lottery when the game ball passes. For the nail unit connected to each other, a game nail having a groove formed in a direction orthogonal to the axial direction is attached so that the extending direction of the groove is substantially orthogonal to the longitudinal direction of the connection. Since the pair of game nails connected by the portions are easily damaged by the load that increases the distance between them, it is possible to suppress an illegal act of expanding the space between the game nails. In each of the above embodiments, the game nail 100D having the groove portions 115 and 116 is used as the game nail constituting the nail unit 200. However, the game nail 100A may be used instead of the game nail 100D. In addition, a game nail 100B or a game nail 100C may be used as a nail member constituting the nail unit 200. In a nail unit that allows a game ball to pass between game nails, for example, a nail unit 200 that replaces a pair of game nails arranged above the start winning opening 25, a game nail 100B is used as a game nail, and a shaft portion It is good also as a structure which arrange | positions the surface containing linear part 101Ba1 in 101B toward inner side.

  In each of the above-described embodiments, the protruding portion 201a of the nail unit 200 is configured to be an elongated bar, but it may be an elongated plate. Further, in each of the above embodiments, the length of the protruding portion 201a is set to such a length that the tip of the protruding portion 201a does not contact the front surface 51 of the game board 50 when the nail unit 200 is attached to the game board 50. However, the length may be such that it contacts the front surface of the game board 50. Moreover, when the hole for inserting the protrusion part 201a is formed in the game board 50, and the nail unit 200 is attached to the game board 50, it is good also as a structure which inserts the protrusion part 201a in a corresponding hole. At this time, the outer diameter of the hole may be larger than the outer diameter of the protruding portion 201a, and by making the outer diameter of the hole corresponding to the protruding portion 201a sufficiently large, the protruding portion 201a has a degree of freedom of movement. be able to. Thereby, the game ball guided along the connecting portion 201 can be easily bounced at the protruding portion 201a.

(7) Modified examples of the groove portions 115 and 116 In each of the above embodiments, the game nail 100D having the groove portions 115 and 116 is used as the game nail constituting the nail unit 200. It may be. In other words, a configuration may be employed in which a shaft portion of a game nail that is attached to the game board 50 is provided with a groove portion that can break the shaft portion, similar to the groove portions 115 and 116. In the case where a groove is formed in a game nail that is independently attached to the game board 50, the game nail is attached to the game board 50 so that the groove is oriented in accordance with the direction of the load applied improperly.

  In each of the above embodiments, a pair of two groove portions 115 and 116 are formed around the shaft portion 101D. However, a groove portion that is continuous with the entire circumference of the shaft portion 101D may be formed. Further, one of the groove 115 and the groove 116 may be formed in the shaft portion 101D.

  In each of the embodiments described above, the groove portions 115 and 116 are groove portions extending in a direction orthogonal to the axial direction of the shaft portion 101D. However, the grooves 115 and 116 have angles other than orthogonal to the axial direction of the shaft portion 101D. It may be a groove portion extending with a gap.

  In each of the above embodiments, the game nail 100D is attached so that the groove portions 115 and 116 face the direction in which the connecting portion 201 extends (that is, the direction substantially orthogonal to the flow-down direction of the game ball). , 116 may be attached to the game nail 100D so as to face in the direction along the flow-down direction of the game ball (that is, the vertical direction in the front view of the game machine). According to this configuration, the strength of the game nail 100 attached to the game board 50 with respect to the direction along the flow-down direction of the game ball can be increased. Therefore, a game ball flows down between a pair of game nails attached above a ball entrance (for example, a start prize port 25) that gives a prize such as a prize ball or a lottery by passing the game ball. About a nail, it can suppress that a game nail breaks with the game ball which flows down.

  On the other hand, according to the configuration of the modified example, the strength of the game nail 100 with respect to the direction substantially orthogonal to the flow direction of the game ball is reduced, so the game nail is damaged by a load that widens the interval between the two game nails. It becomes easy to do. Conventionally, a pair of game nails that are attached above a ball entrance (for example, a start prize port 25) that grants benefits such as prize balls or lottery by passing game balls, Prone to fraudulent acts that facilitate the passage of game balls. On the other hand, as the pair of game nails, game nails having groove portions formed in a direction orthogonal to the axial direction are used, and the direction in which the groove portions extend is relative to the longitudinal direction of the connecting portion. By attaching them so as to be substantially orthogonal, a pair of game nails attached above the entrance, etc., are likely to be damaged by a load that increases the distance between them, so that it is possible to suppress an illegal act of spreading between the game nails. .

  In each of the above-described embodiments, the grooves 115 and 116 are provided in front of the front surface 51 of the game board 50 and closer to the front surface 51 than the head 102 when the game nail 100D is attached to the game board 50. However, it is good also as a structure which provides the groove parts 115 and 116 in the side close | similar to the head 102 in axial part 101D. In this case, it is preferable to provide the grooves 115 and 116 on the side of the head 102 from the contact portion 114. Since the grooves 115 and 116 are provided on the side of the head 102 with respect to the contact portion 114, the possibility of being damaged by contact with the game ball is reduced, so that the game nail 100D is accidentally broken during the game. While reducing the number of cases, it is possible to add a function that makes it easy to find fraud.

  In each of the embodiments described above, the shape of the bottom of the grooves 115 and 116 is a substantially flat surface, but the shape of the bottom may be V-shaped or rounded. By making the bottom shape of the groove portions 115 and 116 narrow such as a V shape or a round shape, the shaft portion 101D can be more easily damaged. Moreover, in each said embodiment, although the shape of the side wall part of the groove parts 115 and 116 was made into linear form, the shape of the said side wall part may be a curve.

(8) Modified example of the general winning device 334 according to the second embodiment In the second embodiment, the general winning device 334 in which the general winning port 324 is formed is described as an example. The same configuration can be applied to a start winning device having a start winning opening, a device having a through gate similar to the through gate 28, and the like.

  In the second embodiment, the pin 401 having an elongated shaft portion is fixed to the base plate 334b, but instead of the pin 401, it is paired with the game nail Q1 and serves as an entrance. A resin portion having a predetermined shape extending upward from the right end of the general prize opening 324 in the front view of the gaming machine (for example, a mountain shape having a peak corresponding to the pin 401 in the front view of the gaming machine) is integrated with the base plate 334b. It may be configured to be formed. According to such a configuration, it is not possible to move or deform the resin portion that becomes the entrance paired with the game nail Q1 from the base plate 334b, so that it is advantageous for the game ball to enter the general winning opening 324. Because of this, cheating is difficult.

  In the second embodiment, the pin 401 is fixed to the base plate 334b on the upper right side of the general winning opening 324 in the front view of the gaming machine, but the pin 401 is connected to the base plate 334b on the upper left side of the general winning opening 324. It is good also as a structure fixed to.

  In the second embodiment, only the pin 401 is fixed to the base plate 334b of the general winning device 334, but a plurality of pins constituting the entrance of the general winning port 324 are fixed to the base plate 334b. There may be.

  In the second embodiment, the two winning holes 55 and 56 are provided on the right side in the front view of the gaming machine with respect to the general winning device 334. However, three or more stopping holes may be provided. Thereby, the attachment aspect of a general winning apparatus can be made into 3 or more types. In the second embodiment, the general winning device 334 is configured such that the stop hole 54 is provided on the left side in the front view of the gaming machine and the stop holes 55 and 56 are provided on the right side. Alternatively, a plurality of stop holes may be provided on the left side.

(9) Modified Examples of Game Nails 100A to 100D In each of the above embodiments, the head 102 has an outer diameter larger than the outer diameter of the shaft portions 101A to 101D (more specifically, the outer periphery of the portion having a circular cross section). Although the game nails 100A to 100D configured as (i.e., thick) are illustrated, the present invention may be applied to game nails in which the outer diameter of the head 102 is smaller than the outer diameter of the shaft portions 101A to 101D. A game nail having an outer diameter of the head portion 102 smaller than the outer diameter of the shaft portions 101A to 101D is, for example, passed from the back surface of the game board 50 (ie, the surface corresponding to the back side of the front surface 51) to the front surface 51 side. It is good also as a structure attached to the game board 50. Moreover, it is good also as a structure which uses the game nail which does not have a site | part from which an outside diameter differs in a protruding end part in which the protruding end part of a shaft part comprises a head.
(10) Modification of Nail Cover In the third to fifth embodiments described above, a pair of game nails that function as entrances to the start winning opening are illustrated as game nails to which the nail cover (for example, the nail cover portion 535b) is attached. However, the nail cover of the present invention can be applied to an appropriate game nail that is driven into the game board 50. The nail cover of the present invention is not limited to being attached to two game nails, and may be configured to be attached to three or more game nails or a single game nail.

  In the third to fifth embodiments, the case where the nail cover is indirectly fixed to the game board 50 via a support member (for example, the main body 535a that supports the nail cover 535b) is illustrated. Further, a leg portion may be provided on the nail cover, and the nail cover may be directly fixed to the game board 50 by the leg portion.

  The nail cover is fixed to the game board 50 or the glass plate 11 directly or indirectly through a support member that supports the nail cover (for example, a main body part 535a that supports the nail cover part 535b). By being configured (that is, the attachment state with respect to the game nail to be attached is fixed), it is possible to prevent the game nail housed in the housing portion of the nail cover from being bent illegally.

  Thereby, for example, the nail cover of the present invention is applied to a part or all of the game nails among a plurality of game nails (so-called guide nails) arranged so as to guide the game balls to the start winning opening. By attaching, the illegal action which makes it easy to guide the game ball to the start winning opening can be suitably suppressed by bending the guide nail upward or downward. In other words, according to the nail cover of the present invention, a game that forms at least a part of a passage leading to the start winning opening, such as a game nail that forms a guide nail and a pair of game nails that function as an entrance to the start winning opening. The act of illegally bending the nail so that it is advantageous to enter the starting winning opening can be suitably suppressed.

  The game nail to which the nail cover of the present invention is attached constitutes at least a part of a passage leading to the start winning opening, such as the start winning opening 525, like a pair of game nails functioning as the start winning opening. Not only the game nails but other than the start winning opening, at least one of the passages leading to an advantageous area (for example, the general winning opening 24, the through gate 28, etc.) that gives a prize such as a winning ball or a lottery by passing the game ball. The game nails constituting the part may be targeted.

  In the third to fifth embodiments, the nail cover such as the nail cover portion 535b is configured to be transparent or translucent, but may be opaque. However, it is preferable that the player can visually recognize the head of the game nail, thereby enabling the player to check the path of the game ball constituted by the game nail.

  In the third to fifth embodiments, the nail cover such as the nail cover portion 535b is not opened on the front side of the storage portion (the storage portion 535b1 or the like) in the front view of the gaming machine, and is stored in the storage portion. The head is not exposed to the front side in the front view of the gaming machine, but the front side of the storage unit in the front view of the gaming machine may be open.

  In the third to fifth embodiments, the nail cover housing portion has an inner wall that covers (encloses) at least a part of the periphery of the head center of the game nail, but the game nail is bent. A wall may be formed in a direction to be regulated. For example, a nail cover to be attached to a pair of game nails functioning as an entrance for a start winning opening is outside the heads of the pair of game nails (that is, the side having the pair of game nails) When the wall is formed on the side opposite to the above, it is possible to suppress the interval between the pair of game nails from being widened.

  In the third to fifth embodiments, the depth of the nail cover accommodating portion is set to a depth that can accommodate the head of the game nail, but may be configured to accommodate a part of the shaft portion. Further, the depth may not necessarily be the depth at which the entire head is accommodated, it may be the depth at which only a part of the distal end side of the head is accommodated, or the circumference around the axis center of the head of the game nail May not be accommodated at all, and may cover only the front side (tip side of the head) (for example, a flat plate structure without depth).

  In the third to fifth embodiments, the game nail 100A in which the outer diameter of the head is larger than the outer diameter of the shaft is exemplified as the game nail accommodated in the nail cover. This may be applied to a game nail whose outer diameter is smaller (smaller diameter) than the outer diameter of the shaft portion.

  In the case of a game nail whose head outer diameter is smaller than the shaft outer diameter, the edge portion including the upper end of the nail cover (such as the upper edge portion 535b2 and the edge portion 735c2) is accommodated in the accommodating portion. The arc shape of a circle having a diameter larger than the outer diameter of the shaft portion of the game nail, centered on a position substantially coinciding with the shaft center of the game nail. In such a case, although a game nail having a head having an outer diameter smaller than the outer diameter of the shaft portion is used, the edge portion including the upper end of the nail cover is similar to the head 102 of the game nail 100A. , Imitating a head with an outer diameter larger than the outer diameter of the shaft portion, thereby providing a pseudo situation where a game nail having a head with an outer diameter larger than the outer diameter of the shaft portion is attached can do.

  In the third to fifth embodiments, the edge part including the upper end of the nail cover (upper edge part 535b2, edge part 735c2, etc.) is illustrated as an arc shape, but a polygonal shape close to a circle, etc. Other shapes may be used.

  In the third to fifth embodiments, the case where the front side of the nail cover is a flat surface is illustrated, but a spherical shape may be used. For example, the front surface side of the nail cover may have a spherical shape including an arc of an edge including the upper end of the nail cover (for example, a spherical shape of a quarter hemisphere).

  In the fourth embodiment, when the front plate portion 635a is slid upward, the game nails Q6 and Q7 are moved left or right by the inclination of the inner walls Z1 and Z2 of the housing portion 635c1. The inner walls Z1 and Z2 may be inclined in the left-right direction so that the game nails Q6 and Q7 move in the left or right direction by sliding the front plate portion 635a downward.

  Further, as the inclination of the inner wall facing the inner walls Z1, Z2 of the housing portion 635c1 (that is, the inner wall on the side where the game nails Q6, Q7 do not contact), the front plate portion 635a is slid upward or downward. In this case, various inclinations in which the game nails Q6 and Q7 move leftward or rightward can be adopted. For example, the inclination of the inner wall on the side facing the inner walls Z1, Z2 of the housing portion 635c1 may be set to be parallel to the inclination of the inner walls Z1, Z2 of the housing portion 63.

  In addition, by setting the inclination of the inner walls Z1 and Z2 of the housing portion 635c1 to be an inclination such that the amount of change in the left-right direction with respect to the unit length in the direction of gravity is sufficiently shorter than the unit length, When the portion 635a is slid upward, the game nails Q6 and Q7 move left or right. The direction in which the game nails Q6 and Q7 are desired to move depends on the inclination of the inner walls Z1 and Z2. Can be changed.

  In the fifth embodiment, the housing portion 735c1 has a truncated cone shape whose opening side is larger than the bottom surface side, so that when the main body portion 735a is slid forward, the game nails Q8 and Q9 are It was configured to move left or right. Instead, when the housing portion 735c1 has a truncated cone shape that is larger on the bottom side than the opening side, and the main body portion 735a is slid rearward, the game nails Q8 and Q9 are left or rightward. It is good also as a structure moved to. Moreover, when the main body 735a is slid forward or rearward without the storage portion 635c1 having a truncated cone shape, various shapes in which the game nails Q8 and Q9 move leftward or rightward can be employed.

  Further, when the main body 735a is slid rearward because the inner wall of the accommodating portion 735c1 having a truncated cone shape is gradually narrowed from the opening side toward the bottom surface, the game nails Q8 and Q9 are left or right. Although it is configured to move in the direction, the direction in which the game nails Q8 and Q9 are to be moved can be changed according to the inclination of the inclined surface of the truncated cone.

  In the fifth embodiment, the main body portion 735a supported by the main body support portion 735b (that is, accommodated in the accommodation space of the main body support portion 735b) is forward with the rear end side entering the game board 50 from the front surface 51. Alternatively, the configuration may be such that the bottom wall 735a2 and the side wall 735a3 of the main body 735a can be expanded and contracted in the front-rear direction (for example, a bellows), and the rear end is connected to the front surface 51. Good.

  In the fourth and fifth embodiments, the position of the front plate portion 635a or the main body portion 735a is finally fixed by using a curable resin. However, the fixing member such as a pin is used to finally fix the position. It is good also as a structure which aims at a fixed position.

  In the fourth and fifth embodiments, the nail cover portions 635c and 735c appropriately prevent the game nails Q6, Q7, Q8, and Q9 from being bent illegally and the game nails Q6, Q7, Q8, and Q9 appropriately. Although it was set as the structure which has both the function which can be positioned, it is good also as a structure which does not have the function which can position a game nail appropriately. That is, in the nail cover portions 635c and 735c, even when the front plate portion 635a or the main body portion 735a is slid, the game nails Q5, Q6, Q7, Q8, and Q9 do not contact the inner walls of the housing portions 635c1 and 735c1. May be.

  In the fourth and fifth embodiments, a breakable portion may be provided at a connection portion between the nail cover portions 635c and 735c and the front plate portion 635a or the front plate 735a1. As the damaged portion, for example, the thickness of the connection portion between the nail cover portions 635c and 735c and the front plate portion 635a or the front plate 735a1 may be reduced, or the width of the connection portion may be reduced. By providing such a damaged portion, when the front nails 635a or the main body 735a are slid in the case where the game nails Q6, Q7, Q8, Q9 are greatly deviated from the design allowable range, the game nails Q6, Q7, Q8 , Q9 contacts the nail cover portions 635c, 735c outside the accommodating portions 635c1, 735c1, thereby making it easy to limit the portion damaged by such a load to the damaged portion. Accordingly, it is possible to easily inform the operator that the game nails Q6, Q7, Q8, and Q9 are far from the design allowable range so that they cannot be adjusted by the nail cover portions 635c and 735c. Also, even if the front plate portion 635a or the main body portion 735a is illegitimately slid, it is possible to report the fraud by damaging the damaged portion, and easily confirming the places where it is necessary to check whether the fraud is present or not. Work can be done.

  (11) The present invention may be implemented in a pachinko machine or the like of a type different from the above-described embodiment, and may be implemented as various game machines such as an arrangement ball type pachinko and a sparrow ball in addition to the pachinko machine. good.
