  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 flowing down is visible from 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. 100 is provided. In the area where a large number of game nails 100 are provided, there are special benefits for players such as the general winning port 24, the starting winning ports 25 and 26, the variable winning device 27 that opens and closes the winning port opened at the time of big hit, the through gate 28, and the like. The entrance holes to be given are provided, and a winning ball is paid out when a game ball enters the entrance, or a lottery such as a big win is performed. As shown in FIG. 2, the game board 20 includes a game board 50 made of synthetic resin that forms the outer shape of the game board 20, and a large number of game nails 100 are driven from the surface side of the game board 50.

  The game board 50 is a plate-like member formed of a transparent resin that holds the game nail 100, and is formed by injection molding a transparent synthetic resin such as a polycarbonate resin or an acrylic resin. The game board 50 does not necessarily need to be formed by injection molding, and a plate-like member formed by extrusion molding may be subjected to router processing to form a through hole or the like to which a decorative member or the like is attached. It is not necessary to form with a single plate-like member, and a plurality of plate-like members may be overlapped. The color of the game board 50 may be colorless and transparent, may be colored and transparent, or may be formed of a colored and opaque synthetic resin that does not have translucency.

  FIG. 3 is a longitudinal sectional view showing a fixed state between the game board 50 and the game nail 100. As shown in FIG. 3, the game nail 100 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 100 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. 3, the game nail 100 includes an elongated shaft portion 101, and a tip end portion (protrusion end portion) that protrudes from one end side of the shaft portion 101 toward the front surface 51 side of the game board 50. And a head portion 102 formed thicker than the shaft portion 101. The game nail 100 is made of metal, for example, made of brass, and formed by subjecting a wire material to a forging process such as rolling.

  The shaft portion 101 has a holding portion 111 that is held by the game board 50 at an end opposite to the head portion 102. The holding portion 111 is formed in a screw shape in which two spiral ridges are formed by knurling. The distal end surface 112 on the further distal end side of the holding portion 111 is formed in a hemispherical shape.

  As shown in FIG. 3, the game ball flowing down between the game board 50 and the glass plate 11 is a part of the shaft portion 101 and has a constant cross-sectional shape between the holding portion 111 and the head portion 102. It abuts on the abutting portion 113 formed in a shape. The game nail 100 is attached to the game board 50 with a certain inclination on the upper side. For example, the game nail 100 attached to the game nail 100 from above is attached with an inclination of 5 degrees above the horizontal. The game ball is guided to the 50 side and is configured to easily fall along the front surface 51 of the game board 50.

  The outer diameter D1 of a portion of the shaft portion 101 where the cross-sectional shape including the abutment portion 113 is formed constant is smaller than the outer diameter D2 of the holding portion 111, and is, for example, approximately 1.85 mm. It is assumed to be the outer shape. The portion corresponding to the contact portion 113 is substantially the same as the outer diameter of the wire as the material, and the holding portion 111 is subjected to plastic deformation larger than the contact portion 113 by forging. For this reason, the holding part 111 is harder than the contact part 113 by work hardening. Here, the outer diameter D <b> 2 of the holding portion 111 is an outer diameter at the maximum portion corresponding to the outer peripheral end of the ridge farthest from the axis that is the center of the shaft portion 101.

  As shown in FIG. 3, most of the holding unit 111 is inserted into the thickness of the game board 50 corresponding to the back side of the front surface 51 of the game board 50, and a part of the game board 50 is part of the game board 50. The length is set to protrude forward from the front surface 51. The amount of protrusion from which the holding portion 111 protrudes to the front side of the front surface 51 of the game board 50 is a slight amount, and is approximately 0.3 mm. When a hammer hitting force for the contact of the game ball or angle adjustment is applied to the protruding portion of the game nail 100, a high bending stress is generated at the edge portion of the nail hole 52 provided in the game board 50, and the nail The contact force between the edge portion of the hole 52 and the surface of the game nail 100 is also high. In this case, since the holding portion 111 whose surface is harder than the contact portion 113 or the like is configured to contact the edge portion of the nail hole 52, breakage of the game nail 100 can be prevented. The length of the holding portion 111 along the axial direction is, for example, approximately 4.0 mm, and the protrusion amount from which the game nail 100 protrudes from the front surface 51 of the game board 50 is, for example, approximately 18.5 mm. Yes.

  Before inserting the game nail 100 into the game board 50, a nail hole 52 having a smaller diameter and a circular cross section than the holding portion 111 is drilled in advance, and the game nail 100 is inserted into the nail hole 52. Specifically, the game nail 100 is inserted into the nail hole 52 while the head 102 is pressed and rotated along the screw shape of the holding portion 111 in the nail hole 52.

  The inner diameter D3 previously drilled as the nail hole 52 has a holding force (hereinafter referred to as a pulling force) that opposes the force in the direction of pulling out the game nail 100 from the game board 50 within a range of approximately 250N to approximately 500N. It is set to become. The pulling force is obtained by measuring the force in the direction of pulling out the game nail 100 along the axial direction with the head 102 held by a tool, and measuring the force with which the game nail 100 is pulled out. It is done. This pull-out force varies depending on the tightening margin corresponding to the difference between the inner diameter D3 of the portion holding the game nail 100 in the nail hole 52 and the outer diameter D2 of the holding portion 111 of the game nail 100, and the pull-out force increases as the tightening margin increases. The pulling force decreases when the tightening margin decreases and the tightening margin decreases.

  With respect to the pulling force, a plurality of types of nail holes 52 having different inner diameters D3 are drilled in the game board 50, and the game nails 100 with a fixed outer diameter D2 of the holding portion 111 are inserted and fixed. Was set by measuring. From this measurement result, the allowable dimensions of the outer diameter D2 of the holding portion 111 and the inner diameter D3 of the nail hole 52 are determined.

  As a result of measuring the pull-out force of the game nail 100 with respect to the game nail 100 having the holding portion 111 of 2.08 mm, the nail hole 52 has an inner diameter D3 of 1.84 mm to 1.88 mm (gradual change range). Each time the inner diameter D3 of 52 changed by 0.01 mm, it changed within the range of 30N to 50N. In this gradual change range, the amount of decrease in the pulling force gradually decreased every time the inner diameter D3 of the nail hole 52 decreased by 0.01 mm. On the other hand, when the inner diameter D3 of the nail hole 52 is 1.89 mm as a range (abrupt change range) in which the inner diameter D3 is expanded from 1.88 mm, the pulling force is greatly reduced as compared with the case of 1.88 mm. The pulling force decreased by 60 N or more with respect to a change of 0.01 mm in the inner diameter D3 of the nail hole 52. In the present embodiment, 1.88 mm at which the pulling force is greatly reduced with respect to the change amount of the inner diameter D3 of the nail hole 52 is set as the reference dimension of the inner diameter D3 of the nail hole 52. The pulling force when the inner diameter D3 of the nail hole 52 was 1.88 mm was about 440N.

  The difference in the inner diameter D3 of the nail hole 52 affects the feel when the angle of the game nail 100 is adjusted to a predetermined angle by hitting the head 102 of the game nail 100 with a hammer. The synthetic resin game board 50 is harder than the wooden game board, and the feel of hitting the game nail 100 held in the nail hole 52 is hard in the synthetic resin game board 50, and the wooden game Soft on the board. This difference also affects the behavior of the game ball that comes into contact with the game nail 100. In the case of a wooden game board, the game ball that comes into contact with the game nail is likely to rebound, and in contrast, in the game board 50 made of synthetic resin. Is hard to resist.

  Further, the durability of the game nail 100 against repeated bending also changes depending on the difference in the inner diameter D3 of the nail hole 52. Specifically, a force is applied to the head 102 of the game nail 100 to plastically deform the game nail 100 alternately on one side and the other side parallel to the front surface 51 of the game board 50, for example, the left side and the right side. When the bending deformation accompanied with is caused, the larger the inner diameter D3 of the nail hole 52, that is, the lower the pulling force, the more the number of times the game nail 100 is bent until it breaks, and the higher the durability. Even in the result of repeatedly applying a force to a location corresponding to the contact portion 113 of the game ball and performing a durability test without plastic deformation, the durability increases as the inner diameter D3 of the nail hole 52 increases, that is, the pull-out force decreases. Became high.

  The pull-out force of the game nail 100 is about 250 N in the wooden game board, and in this embodiment, the game nail is brought close to the behavior of the game ball on the wooden game board and the feeling when adjusting the game nail 100. The pulling force of 100 is set to be in the range of about 250N to about 500N. As the setting of the pulling force, for example, approximately 250N to approximately 400N is preferable, and approximately 250N to approximately 350N is preferable. However, as the allowable range of the pull-out force is narrowed, the dimensions of the inner diameter D3 of the nail hole 52 and the outer diameter D2 of the holding portion 111 need to be strictly controlled. It is preferable to do.

  FIG. 4 is a diagram schematically showing two game nails 100 provided in the upper part of the upper start winning opening 25. The two game nails 100 are bent in the direction in which the heads 102 are separated from each other. The angle of the two game nails 100 is set by setting the interval between the base portions of the head 102 to a predetermined interval W by inserting a metal gauge 30 having a thin plate shape and set to the interval W. As the predetermined interval W, the width of the head 102 of the game nail 100 is widened from the base side of the game nail 100 so that the game ball can easily enter the start winning opening 25 as viewed from the player. . However, depending on the pulling-out force of the two game nails 100 and the surrounding game nails 100, even if the game nails 100 are arranged at the same arrangement, the same interval, and the same angle, the game balls to the start winning opening 25 Will have different winning probabilities. For players accustomed to conventional pachinko machines, if the probability of winning a prize is low compared to the appearance, it may be aversion to amusement halls and machine manufacturers. The force is preferably set to a low value close to the wooden game board. Accordingly, it is possible to provide a gaming machine in which the behavior of the game ball in contact with the game nail 100 is close to the behavior of the game ball on the wooden game board and is easily familiar to skilled players.

  Thus, in the pachinko machine 10, the holding portions 111 as hard portions whose surfaces are harder than the contact portions 113 in the game nail 100 are positioned on both the front and rear sides with respect to the front surface 51 of the game board 50. For this reason, even if the game nail 100 comes into contact with the edge portion of the nail hole 52 on the front surface 51 of the game board 50, that portion is a harder portion than the contact portion 113. Therefore, breakage of the game nail 100 due to the contact between the edge portion of the nail hole 52 and the game nail 100 can be suppressed, and the adjustment operation of the game nail 100 on the resin game board 50 can be suitably performed.

  Further, the holding portion 111 whose surface is harder than the contact portion 113 is in a state of slightly protruding from the front surface 51 of the game board 50. Therefore, by visually recognizing the boundary position between the holding portion 111 and the shaft portion 101 that is softer than the holding portion 111, it can be easily confirmed whether or not the game nail is in the specified position, and the game nail 100 is in the specified position. Easy to manage. Further, since the game board 50 is transparent, the holding part 111 can be seen through the transparent game board 50, and further, the protruding amount of the holding part 111 protruding forward from the front surface 51 of the game board 50 is small. There is no big difference in appearance between the holding part 111 and the part that has entered the back side from the front surface 51 of the game board 50 completely. In a conventional pachinko machine using a plastic game board, the holding part is positioned on the back side of the front face of the game board, but the appearance does not change from that of the pachinko machine, and it is easy to manage the game nail 100 at a specified position. Can be a machine.

  Further, the pulling force of the game nail in the conventional resin game board is set to a value larger than 500 N corresponding to more than twice the pulling force in the wooden game board. As compared with wooden game boards, the plastic game board has a large change in the pulling force with respect to the change in the tightening allowance. Since the amount of change with respect to the change in the inner diameter is reduced, the tightening allowance is increased to a dimension where the amount of change is reduced, and accordingly, the pulling force of the game nail has a large value.

  On the other hand, in the pachinko machine 10 according to the present invention, the allowance for pulling out the game nail 100 in the resin game board 50 is set low, and the holding force for the game nail 100 is kept low. Due to this decrease in holding power, the feel of adjusting the angle of the game nail 100 is soft and the workability is good, and the behavior of the game ball in contact with the game nail 100 is close to the behavior of the game ball on the wooden game board. The gaming machine can be easily familiar to a player.

  Here, instead of the first embodiment described above, the result of the game, such as winning a prize opening or the like, without strict dimensional management so as to set the pull-out force for all the game nails 100 low. Only the pulling force with respect to the game nail 100 (specific game nail 100a) that easily affects the game may be lowered. As shown in FIG. 3, a plurality of specific game nails 100a provided at a specific part 61 such as an upstream side of the winning opening, the vicinity of the entrance of the winning path, or a part where a game ball entering the game area 21 first comes into contact. In the nail hole 52 provided with the inner diameter D3, the median value of the allowable dimension may be set larger than that of the other nail holes 52. That is, the dimensions of the game nail and the nail hole are set so as to have a plurality of types of engagement structures with different tightening allowances, and the nail hole 52 of the specific game nail 100a is 0.01 mm larger or smaller than the standard dimension of 1.88 mm. The general game nail 100b other than the specific game nail 100a has an allowable dimension from minus 0.01 mm to plus 0.03 mm with respect to the reference dimension. Although the difference in average dimension is 0.01 mm, the processing speed can be increased and the management cost can be reduced for the nail hole 52 with an increased allowable dimension, and the angle can be adjusted during manufacturing. With respect to the specific game nail 100a that is easily applied, the functionality can be improved, for example, the durability and the feel of hitting with a hammer can be softened.

  Next, another mode for reducing the pulling force of the specific game nail 100a as compared with the general game nail 100b will be described. FIG. 5 is a longitudinal sectional view showing a fixed state of the game nail 100 on the game board 200 in the second embodiment. The above-described first embodiment and the game nail 100 have the same shape, and the shape of the nail hole is different. Hereinafter, the same components as those in the first embodiment are denoted by the same reference numerals, description thereof will be omitted, and portions different from those in the first embodiment will be described.

  As shown in FIG. 5, the nail hole 202 in the second embodiment is formed in a circular hole shape with a stepped cross section having a large inner diameter D <b> 4 on the front surface 201 side from which the game nail 100 protrudes in the game board 50. The inner diameter D3 is smaller than the inner diameter D4 on the front surface 201 side. The holding portion 111 of the game nail 100 is held by a portion of the inner diameter D3 on the back side. The amount of protrusion of the game nail 100 from the front surface 201 of the game board 200 is set to be the same as the amount of protrusion in the first embodiment, and a part of the holding portion 111 is located on the front side of the front surface 201 of the game board 200. . The stepped nail hole 202 is provided at a position where the specific game nail 100a is disposed, and the general game nail 100b is provided with the nail hole 52 having a constant cross section in the first embodiment. 2 and 3).

  The stepped nail hole 202 is formed so that the inner diameter D3 smaller than the holding portion 111 penetrates the game board 200 before and after the game board 200, and the inner diameter D4 larger than the holding portion 111 is different from that process. It forms in the part which does not penetrate from the front surface 201 side of the board 200 to a back surface. The step of forming the large inner diameter D4 may be formed before or after the inner diameter D3 on the back side.

  The inner diameter D3 of the nail hole 52 of the general game nail 100b is set to the same reference dimension as the inner diameter of the stepped nail hole 202, which is smaller than the reference dimension in the first embodiment, for example, 0.02 mm smaller. Although the pulling force of the game nail 100 is increased by the reduction of the reference dimension, the holding length held by the inner diameter D3 in the axial direction of the holding portion 111 is formed short in the stepped nail hole 202 and is stepped. The pulling force of the specific game nail 100a held in the nail hole 202 is lower than that of the general game nail 100b. By comprising in this way, the internal diameter D3 of the part holding the holding | maintenance part 111 of the general game nail 100b and the specific game nail 100a can be made common, and it can process with the same tool. When machining the inner diameter D3 on the back side of the specific game nail 100a, the tool axis is less likely to be shaken by making the machining speed slower than when machining the inner diameter D3 of the general game nail 100b. A high inner diameter D3 can be formed.

  Further, the holding portion 111 for holding the game nail 100 is such that the specific game nail 100a is on the back side from the front surface 201 of the game board 200, and even if the game nail 100 is provided with the same protrusion amount, the specific game nail 100a The game ball is easy to bounce, and the behavior of the game ball close to a wooden game board can be easily realized by the game board 200 made of synthetic resin.

  Next, a third embodiment will be described. In the third embodiment, the shape of the game nail 100 is different from those of the first embodiment and the second embodiment, and the game board 50 is formed thick. FIG. 6 is a longitudinal sectional view showing a fixed state of the game nail in the third embodiment. Hereinafter, the part different from 1st Embodiment is demonstrated about the fixing structure of the game nail in 3rd Embodiment.

  The game nail 150 according to the third embodiment is provided with a constricted portion 152 having a narrow outer periphery at a portion close to the holding portion 111, and the shaft portion between the head portion 102 and the holding portion 111 does not have a constant cross-sectional shape. The length of the constricted portion 152 is longer than the game nail 100 in the first embodiment. The constricted portion 152 is formed by thinly forging a brass wire, and has a harder surface than the contact portion 113 or the like on which the game ball contacts by work hardening. The constricted portion 152 has the thinnest central portion in the length direction of the shaft portion 151, and both sides thereof are gradually formed thicker, and are formed in a concave shape in an arc shape in a side view. The length of the constricted portion 152 in the axial direction is, for example, 2 mm, and the diameter of the minimum portion is, for example, 1.75 mm. A part of the constricted portion 152 is located so as to protrude 0.3 mm forward from the front surface 301 of the game board 300, and the remaining part is located within the thickness of the game board 300. The game board 300 is formed to be thicker than the game board 50 in the first embodiment, and the holding portion 111 of the game nail 150 is held in the entire area along the axial direction of the shaft portion 101. The inner diameter D3 of the nail hole 302 is the same as the inner diameter D3 of the nail hole 52 in the first embodiment described above.

  By providing the game nail 150 in the third embodiment on the game board 300, the distance between the contact portion 113 and the holding portion 111 with which the game ball abuts is increased compared to the game nail 100 in the first embodiment. The game ball can be easily bounced and the behavior of the game ball close to a wooden game board can be realized by the game board 300 made of synthetic resin.

Each member can be screwed into and supported with respect to 543. Three members are screwed and supported at three positions with respect to the base member 511, and these male and female screws may be formed by screw shapes having the same size and shape at three positions. Thus, the male screw forming operation of the base member 511 can be simplified with the same tool. On the other hand, the male screw and the female screw may be formed by screw shapes having different sizes and shapes at the three locations. In this case, the two support members 516 and 517 other than the positions shown in FIG. And the receiving member attachment shaft 514 can be made unattachable. Here, of the two support members 516 and 517, the side provided at the distal end side protruding portion 544 is referred to as a distal end side support member 516, and the side provided at the proximal end side protruding portion 545 is referred to as a proximal end side support member 517. .

  As shown in FIG. 9, the base end side support member 517 is a metal cylindrical member in which a through hole is formed in the central portion so that the central axis is coaxial with the through hole of the base end side protruding portion 545. is there. A male screw that can be screwed into a female screw of the base end side protruding portion 545 is formed on the outer peripheral surface of the base end side supporting member 517, and is screwed into the through hole of the base end side protruding portion 545 so that the axial direction of the through hole is increased. The base end side support member 517 is movable along the axis.

  As shown in FIGS. 8 and 9, two operation members 518 and 519 are provided on one end side of the base end side support member 517. One of the operation members 518 and 519 is a rotation operation member 518 that is rotated by an operator, and the other is an operation member 512 that is fixed to the base end side support member 517 in a replaceable manner. It is the fixed operation member 519 for this.

  As shown in FIG. 9, the rotation operation member 518 includes a cylindrical portion 551 in which a female screw is formed on the inner surface of a cylindrical portion, and the cylindrical portion 551 has a central axis coaxial with the cylindrical portion. This is a metal member joined to a disc-shaped handle portion 552 having a diameter larger than 551 and having a recessed portion on the outer peripheral surface. The internal thread portion of the inner surface of the tubular portion 551 is set to a size corresponding to the external thread formed on the outer peripheral surface of the proximal end side support member 517, and the proximal end side support member 517 is screwed into the tubular portion 551. In the state, the fixing screw 521 is screwed from the outside of the cylindrical portion 551 toward the central axis side of the base end side support member 517, so that the fixing screw 521 is pressed against the base end side support member 517. The base end side support member 517 and the rotation operation member 518 are fixed and integrated.

  A central portion of the handle portion 552 of the rotation operation member 518 is provided with a female screw having a central axis extending from the central axis of the female screw of the cylindrical portion 551 and a smaller diameter than the female screw portion of the cylindrical portion 551.

  As shown in FIG. 9, the fixing operation member 519 overlaps with the handle portion 552 of the rotation operation member 518 and has a disk-like fixing operation portion 553 formed with a smaller diameter than the handle portion 552, and a fixing operation portion. This is a metal member having a cylindrical shaft-shaped fixed shaft portion 554 that extends to one side from the center portion of 553 and has an external thread formed on the outer peripheral surface thereof. The fixed operation member 519 is opposite to the side on which the proximal end support member 517 is located with respect to the rotation operation member 518 in a state where the proximal end support member 517 and the rotation operation member 518 are integrated. It is a member that closes the opening hole. When the operation member 512 is inserted into the hole and then the fixed operation member 519 is screwed into the rotation operation member 518, the movement of the operation member 512 toward the fixed operation member 519 is prevented. As a result, by rotating the rotation operation member 518 with respect to the base member 511, the rotation operation member 518 can advance along the central axis of the base end side support member 517, and the end of the operation member 512 can be moved. By positioning the fixing operation member 519 on the side (upper side in FIG. 9), the operation member 512 advances together with the fixing operation member 519, and a pressing force is applied to the game nail by the operation member 512.

  The front end side support member 516 is a cylindrical metal member in which a through hole is formed in the central portion so that the through hole of the front end side protruding portion 544 is coaxial with the central axis. The front end side portion of the operating member 512 is supported in the through hole of the front end side supporting member 516, and the pressing force when the game nail is pushed out or inserted is played by the operating member 512 supported by the front end side supporting member 516. Transmitted to the nail. As shown in FIG. 10 (a), the actuating member 512 and the front end side supporting member 516 are formed by combining the pushing support member 561 and the pushing actuating member 562 for pushing out the broken game nail, and FIG. ), The combination of the insertion support member 571 for inserting the game nail and the combination of the operation member 572 for insertion, and the two types of combinations corresponding to the extrusion operation and the insertion operation have different shapes. Is set in

  As shown in FIG. 10A, the pushing operation member 562 is a metal member formed so that columnar members having different outer diameters are continuous so that the central axes are positioned on a straight line. . The pushing operation member 562 has a cylindrical pushing tip portion 581 formed on a thin shaft having a tip face abutting on the game nail on one end side, and a pushing tip continuously on the other end side of the pushing tip portion 581. An extrusion shaft portion 582 formed in a cylindrical shape that is thicker than the portion 581 and longer than the extrusion tip portion 581, and a head of a thicker shaft than the extrusion shaft portion 582 that is positioned on the opposite side of the extrusion tip portion 581 with respect to the extrusion shaft portion 582 Part 583. The distal end surface of the extrusion distal end portion 581 is formed in a planar shape perpendicular to the central axis of the pushing operation member 562, and a pressing force is applied to the broken game nail along the central axis of the pushing operation member 562. It is configured.

  Here, as shown in FIG. 9, the through hole of the base end side support member 517 is formed to have a circular inner diameter slightly larger than the extruded shaft portion 582 over the entire length, and the outer peripheral surface of the extruded shaft portion 582. Can be supported. One end portion side of the through hole of the base end side support member 517 has a shape provided with a step so that the head portion 583 of the pushing operation member 562 can enter, and the head portion 583 of the pushing operation member 562 is illustrated in FIG. As shown in FIG. 9, the base end side support member 517 and the fixed operation member 519 are sandwiched. Therefore, by rotating the rotation operation member 518 with respect to the base member 511, the rotation operation member 518, the fixed operation member 519, the base end side support member 517, and the pushing operation member 562 are integrated. In this state, it can be advanced or retracted along the axial direction of the pushing operation member 562 (operation member 512). In a range in which the member integrated with the push-out operation member 562 can travel along the axial direction, the rotation operation member 518 abuts on a recessed portion 531 that is recessed in an L shape on the outer peripheral surface of the base member 511. This position is the maximum advancing state in which the pushing operation member 562 (operation member 512) has moved most to the receiving member 513 side.

  The extrusion tip 581 is set to have an outer diameter that is thinner than the shaft portion of the game nail, and is set to an outer diameter that is smaller than the inner diameter of a nail hole formed in the game board. The length of the extrusion tip portion 581 is set sufficiently long so as to penetrate the nail hole of the game board in a state where the extrusion shaft portion 582 is supported by the extrusion support member 561. In addition, when the rotation operation member 518 is in the maximum advancing state in which the rotation operation member 518 is in contact with the recessed portion 531 of the base member 511, the distal end of the extrusion distal end portion 581 faces the distal end side protruding portion 544 side of the receiving member 513. The length is set so as to enter the virtual plane obtained by extending the inclined surface, and is set to the length protruding from the rear surface of the game board in the maximum progress state.

  As shown in FIG. 10B, the extrusion support member 561 is a cylindrical metal member having three different outer diameters and two different inner diameters. As shown in FIG. 10 (a), the extrusion support member 561 has a male screw portion 584 having a male screw formed on the outer peripheral surface as an intermediate portion, and a tip portion having an outer diameter smaller than the male screw portion 584 on one side. And a knob portion 586 having an outer diameter larger than that of the male screw portion 584 on the opposite side. The knob portion 586 is a portion that is picked when the operator pushes the pushing support member 561, and is preferably provided with a non-slip shape such as a rolling process in which the outer peripheral surface is recessed in a net shape.

  The through-hole penetrating at the central portion of the extrusion support member 561 is formed with an inner diameter that is smaller than the outer diameter of the extrusion shaft portion 582 of the extrusion operation member 562 and slightly larger than the extrusion tip portion 581 on the distal end portion 585 side. A distal end side hole 587 that supports the outer periphery of the extrusion distal end portion 581, and a proximal end side that is formed to have an inner diameter that is larger than the distal end side hole 587 and slightly larger than the extrusion shaft portion 582 and supports the outer periphery of the extrusion shaft portion 582. And a support hole 588.

  As shown in FIG. 10, a cylindrical spacer 522 formed as a separate component from the extrusion support member 561 is provided on the front side of the distal end portion 585 of the extrusion support member 561. The spacer 522 is a member that contacts the front surface of the game board, and is formed of a material softer than metal, such as silicon rubber. The spacer 522 is interposed between the pushing support member 561 and the game board during the game nail replacement operation, and prevents the game board from being damaged.

  The outer diameter of the spacer 522 is set to a circular outer diameter that is substantially the same as the outer diameter of the distal end portion 585 of the extrusion support member 561, and the inner diameter of the through-hole provided in the spacer 522 is the distal end of the extrusion support member 561. The size is set so as to be substantially coincident with the side hole 587 and to be inserted through the extrusion tip 581.

  Of the end faces on both ends along the through hole of the spacer 522, one end is formed perpendicular to the central axis of the through hole, faces the tip 585 of the support member 561 for extrusion, and contacts in a state of being in close contact with each other. It is possible. On the other hand, the end surface of the spacer 522 that is in contact with the game board is not perpendicular to the central axis of the through hole of the spacer 522, as shown in FIGS. 10 (a) and 11 (a). It is formed in an inclined plane shape, for example, a surface shape facing the direction side inclined approximately 5 degrees. As described above, since the game nails are provided to be inclined rather than perpendicular to the front surface of the game board, the end surface of the spacer 522 is provided to be inclined with respect to the through hole by an angle corresponding to the inclination. The spacer 522 can be disposed along the axial direction of the game nail while the pressure on the front surface of the game board is closely distributed to disperse the pressure and the front face of the game board is hardly damaged. It is movable along the axial direction of the game nail.

  Further, since the spacer 522 is formed as a separate part from the extruding support member 561, the spacer 522 is rotatable with respect to the central axis of the extruding operation member 562 with respect to the base member 511 that supports the extruding support member 561. It is said. Therefore, as shown in FIG. 9, the one end surface of the spacer 522 is inclined in a side view, or the spacer 522 is rotated 90 degrees or 180 degrees from that state to be inclined to another direction. The spacer 522 can be arranged in an inclined state in various directions, and the spacer 522 can be placed on the game board regardless of which side the base member 511 is positioned with respect to the game nail to be operated. The work can be performed in close contact with the front surface.

  As shown in FIG. 11A, a groove-like vertical groove portion 522 a extending in parallel with the through hole of the spacer 522 is provided on the outer peripheral surface of the spacer 522. The vertical groove portion 522a is provided on one side of the spacer 522 corresponding to the intermediate position of the height of the inclined surface facing the receiving member 513 (the rear side in the vertical direction in FIG. 9). The direction of the vertical groove portion 522a By adjusting the direction of the inclined surface of the spacer 522 while confirming the above, the direction of the spacer 522 can be easily and accurately adjusted.

  As shown in FIGS. 10A and 10C, the insertion actuating member 572 is formed in a shape in which the extrusion tip portion 581 is removed from the extrusion actuating member 562, and the extrusion shaft portion 582 is formed. And the insertion shaft portion 592 set to have substantially the same thickness and length, and the pushing operation member 562 and the head portion 593 having substantially the same shape. The end surface of the insertion shaft portion 592 is formed in a substantially hemispherical shape in which the position corresponding to the central axis is most recessed as shown in a partial cross-sectional view in FIG. When a pressing force is applied to the nail, the game nail is inserted while the head of the game nail is guided to the center side of the insertion shaft portion 592. Further, in the maximum progress state in which the rotation operation member 518 is in contact with the base member 511, the length of the game nail to which the pressing force is applied is inserted into the game board at substantially the same depth as other game nails. The length of the insertion shaft portion 592 is set. As shown in FIG. 10 (c), the concave shape of the end surface of the insertion shaft portion 592 is a spherical surface having the same radius as the spherical shape of the head of the game nail or a radius larger than the radius of the spherical shape of the head of the game nail. It is preferable that it is formed in a partial shape because the game nail can be guided to the center side. Further, the end surface of the insertion shaft portion 592 does not necessarily have a concave shape, and may be formed in a planar shape perpendicular to the central axis of the insertion shaft portion 592.

  As shown in FIGS. 10A to 10D, the insertion support member 571 has a male screw portion 594 and an outer diameter smaller than the male screw portion 594, as with the support member 561 for extrusion. The front end portion 595 and the knob portion 596 having an outer diameter larger than the male screw portion 594 and a rolling process that is recessed in a net shape on the outer peripheral surface are provided as outer surface shapes. Further, as a through hole penetrating in the central portion of the insertion support member 571, a distal end side hole 597 formed on the distal end portion 595 side with an inner diameter smaller in diameter than the insertion shaft portion 592 of the insertion operation member 572, And a base end side support hole 598 that is formed to have a larger inner diameter than the distal end side hole 597 and slightly larger than the insertion shaft portion 592 and support the outer periphery of the insertion shaft portion 592.

  Further, the insertion support member 571 is provided with a through-groove 599 penetrating in a radial direction spaced apart from the central axis at a part of the tip portion 595 as a portion not provided in the extrusion support member 561. The front end side hole 597 of the insertion support member 571 is formed to have an inner diameter slightly larger than the shaft portion of the game nail, and is set to a size that supports the outer periphery of the shaft portion of the game nail. Further, the base end side support hole 598 of the insertion support member 571 is formed to have an inner diameter that is larger than the distal end side hole 597 and slightly larger than the head of the game nail. The size is set to support the outer periphery of the portion 592. That is, the size of the proximal support hole 598 of the insertion support member 571 is determined with reference to the head of the game nail, and the proximal end side of the insertion support member 571 is substantially equal to the size. The inner diameter of the support hole 598 is set, and the outer diameters of the shaft portions 582 and 592 of the actuating members 562 and 572 are set so as to substantially coincide with the inner diameter of the base end side support hole 598. Yes. For this reason, in the game nail exchanger 500, a combination of the extrusion support member 561 and the extrusion operation member 562, the insertion support member 571, and the difference are used while utilizing a common base side support member 517 or the like. The combination of the insertion actuating member 572 can be replaced so that the game nail push-out operation and the insertion operation can be executed.

  As shown in FIG. 11B, the through groove 599 of the insertion support member 571 has a circular shape in a side view provided at an end portion on one end side (upper side in FIG. 11B) corresponding to the bottom portion of the groove. The opening 601 and a long groove 602 that is narrower than the diameter of the circular opening 601 and spaced at a constant interval are formed into a continuous groove shape. The width of the long groove portion 602 is set to be slightly narrower than the distal end side hole 597 of the insertion support member 571 and larger than the diameter of the shaft portion of the game nail, and the opening 601 is formed at the head of the game nail. The diameter is set larger than the maximum diameter of the part. Therefore, the game nail can be disposed in the through hole of the insertion support member 571 through the through groove 599, and the game nail disposed in the through hole can be disposed through the through groove 599 of the insertion support member 571. It can be arranged relatively outside.

  As shown in FIG. 9, the receiving member 513 is at one end thereof with respect to a metal receiving member mounting shaft 514 having an outer peripheral surface on which a male screw to be screwed into the receiving side protruding portion 543 of the base member 511 is formed. This is a member that is attached to the side of the game board recess 533. As shown in FIG. 11C, the receiving member 513 is formed by overlapping two members formed in an annular shape, and a receiving surface portion 611 formed of a resin such as silicon rubber softer than metal, The receiving support portion 612 is bonded and fixed. The surface of the receiving surface portion 611 on the front end side protruding portion 544 side forms a receiving portion that comes into contact with the game board, and the receiving surface portion 611 is made of a soft resin, so that even if the receiving surface portion 611 comes into contact with the game board, it is damaged. It is considered difficult. Like the spacer 522, the receiving surface portion 611 is formed such that the surface on the side in contact with the game board is not perpendicular to the receiving member mounting shaft 514 but is inclined, and the base member on which the receiving member mounting shaft 514 is supported. The receiving surface portion 611 is rotatable with respect to the central axis of the receiving member mounting shaft 514 with respect to 511. The receiving surface portion 611 and the spacer 522 are formed to be inclined by, for example, 5 degrees corresponding to an angle at which the game nail is not perpendicular to the front and rear surfaces of the game board, and the inclined surfaces of the receiving surface portion 611 and the spacer 522 As shown in FIG. 9, the game board can be fixed in a stable state by being fixed so as to sandwich the game board in parallel.

  The receiving surface portion 611 has a large diameter in the radial direction that is separated from the central axis with respect to the outer diameter of the spacer 522, and specifically, is set to a size approximately three times as large in all directions. For this reason, when a pressing force is applied to the spacer 522 toward the center portion of the receiving surface portion 611, the inclined surfaces of the receiving surface portion 611 and the spacer 522 are easily changed to a parallel state.

  The receiving support portion 612 is provided with a through hole that penetrates in the radial direction from the center portion of the receiving member 513 and has an internal thread formed on the inner peripheral surface. The through hole is shown in FIG. As shown, the receiving member 513 can be fixed to the receiving member mounting shaft 514 by inserting the fixing screw 523 and pressing the distal end portion of the fixing screw 523 against the outer peripheral surface of the member mounting shaft 514. The fixing screw 523 is provided on one side of the receiving member 513 corresponding to the middle position of the height of the inclined surface (the back side in the direction perpendicular to the paper in FIG. 9). The direction of the fixing screw 523 is confirmed. While adjusting the direction of the inclined surface of the receiving member 513, the direction of the receiving member 513 can be adjusted more accurately.

  The fixing screw 523 that can confirm the orientation of the inclined surface in the receiving member 513 and the vertical groove portion 522a that is provided on the outer peripheral surface of the spacer 522 and can confirm the orientation of the inclined surface of the spacer 522 are both used for rotation operation. It is provided on the outer peripheral surface separated from the center and is set so as to be easily visible to the operator. Further, in the direction in which the inclined surfaces facing each other in the receiving member 513 and the spacer 522 are parallel, the same direction side (perpendicular to the paper surface in FIG. 9) with respect to the rotation center axis when adjusting the direction of the receiving member 513 and the spacer 522. The fixing screw 523 of the receiving member 513 and the longitudinal groove portion 522a of the spacer 522 are disposed on the back side in the direction. For this reason, for example, when it is desired to obtain the state shown in FIG. 522a and the fixing screw 523 may be disposed. By this adjustment operation, a portion formed so as to approach the spacer 522 in the receiving member 513 on one side (the right side in FIG. 9) with respect to the rotation center axis of the receiving member 513 and the spacer 522 and the receiving member in the spacer 522 A part far from 513 is located, and a part far from the spacer 522 in the receiving member 513 and a part located on the receiving member 513 side in the spacer 522 are located on the opposite side (left side in FIG. 9). Therefore, the operator can easily set the orientation of the receiving member 513 and the spacer 522 to be parallel to the front and rear surfaces of the game board with the vertical groove 522a and the fixing screw 523 as marks, so that the game nail can be replaced efficiently. Can be implemented. In particular, when the game board is permeable and the rear side is visible from the front side, the position of the fixing screw 523 is confirmed even when the game board is sandwiched between the spacer 522 and the receiving member 513. However, the position of the longitudinal groove 522a can be adjusted, and the orientation adjustment of the spacer 522 and the receiving member 513 is further facilitated.

  As shown in FIG. 9, the receiving member mounting shaft 514 to which the receiving member 513 is attached to one end side is longer than the through hole of the receiving side protruding portion 543 so that the opposite end passes through the receiving side protruding portion 543. A receiving portion fixing member 515 is provided at the opposite end portion. The receiving portion fixing member 515 is formed in an annular shape having a through hole with a female screw formed in the center, and the outer peripheral surface thereof is formed in a undulating manner along the thickness direction so that the operator can receive the receiving portion fixing member. It is easy to apply a force to the receiving portion fixing member 515 during the rotation operation of 515. The operator first loosens the receiving portion fixing member 515 so as to be separated from the base member 511, and then determines the direction of the inclined surface of the receiving member 513 integrated with the receiving member mounting shaft 514 by the fixing screw. 50 and the base member 511 are rotated in an appropriate direction determined by the positions of the base member 511. If the receiving portion fixing member 515 on the opposite side of the receiving member mounting shaft 514 is screwed and brought into contact with the outer side surface of the receiving side protruding portion 543 after being set in an appropriate orientation, the contact force As a result, the receiving member mounting shaft 514 cannot be rotated with respect to the base member 511, and the receiving member 513 can be fixed to the base member 511.

  A hole portion 613 having an opening on one side along the axial direction is provided in the central portion of the receiving member mounting shaft 514, and the receiving side protruding portion 543 is formed so that the side on which the hole portion 613 is provided is the receiving member 513 side. It is attached. The hole 613 communicates with the through-hole of the receiving member 513, and is fixed to the receiving-side protruding portion 543 in a state in which the side on which the extruding operation member 562 is provided opens and extends in the traveling direction side of the extruding operation member 562. . The broken game nail pushed out of the game board by the pushing operation member 562 enters the hole 613 of the receiving member mounting shaft 514 and is received by the receiving member mounting shaft 514.

  Here, it is preferable that the hole 613 of the receiving member mounting shaft 514 is set to have a longer length from the entrance to the bottom than the full length of the game nail to be replaced. Further, the hole 613 of the receiving member mounting shaft 514 contacts the rear surface of the game board in a state where the pachinko machine 10 is installed so that the inclined surface of the receiving member faces and closely contacts, and the movement of the pushing operation member 562 When the direction and the axial direction of the nail hole into which the game nail is inserted are substantially matched, it is preferable that the bottom surface be inclined downward toward the back side. That is, when the game board is provided with a nail hole so that the game nail is attached with an inclination of 5 degrees upward with respect to the game board, the direction in which the inner diameter of the hole portion 613 continues is the moving direction of the pushing operation member 562. It may be parallel, that is, it may have a circular cross section with a constant inner diameter, and the inner diameter on the back side gradually becomes smaller at an inclination angle less than 5 degrees, for example, corresponding to the angle at which the game nail is inclined with respect to the game board. When the game nail is pushed out, the bottom surface of the hole 613 is preferably inclined downward toward the back side. The cross-section of the hole 613 of the receiving member mounting shaft 514 may be a shape other than a circle, but the game nail changer 500 can be arranged in any of the top, bottom, left, and right directions with respect to the game nail. However, it is preferable that the bottom surface of the hole 613 is inclined downward at a certain angle. In addition, as the hole 613 of the receiving member mounting shaft 514, the inner diameter may gradually be formed on the bottom side corresponding to the traveling direction side of the pushing operation member 562. In this case, the broken game nail Is more easily guided to the back side, which is preferable. In addition, the bottom side of the hole 613 may be open, but it is not penetrating, or in the case of a penetrating shape, providing a lid member that can close the bottom side is a broken game nail It is preferable that the occurrence of problems such as falling to the rear side of the game board and hindering the flow of the game ball can be suppressed.

  Next, an operation method of the game nail exchanger 500 will be described. 12 and 13 are explanatory views showing the procedure for replacing the members of the game nail exchanger 500. FIG. In the operation using the game nail changer 500, first, the operation member 512 and the distal end side support member 516 attached to the game nail changer 500 are confirmed, and if necessary, these members are replaced with other members. Thus, a game nail exchanger 500 suitable for work is obtained.

  As a procedure for exchanging the operating member 512 and the distal end side support member 516, a procedure for exchanging the combination of the extrusion support member 561 and the extrusion operation member 562 with the combination of the insertion support member 571 and the insertion operation member 572 is used. An example will be described. In the exchange, first, the fixed operation member 519 is rotated relative to the rotation operation member 518 in a loosening direction, and the rotation operation member 518 is removed from the fixed operation member 519 (see FIG. 12A). Next, the push-out operation member 562 is extracted from the rotation operation member 518 by setting the opening hole portion of the rotation operation member 518 downward or the like (see FIG. 12B).

  After the push-out operating member 562 is extracted, the knob 586 of the push-out support member 561 is operated, and the push-out support member 561 is pulled out from the operation recess 532 (see FIG. 12C). Thereafter, the insertion support member 571 and the insertion operation member 572 are sequentially attached to the base member 511, and finally, the fixed operation member 519 is tightened from the end side of the rotation operation member 518 to complete the member replacement (FIG. 13). By reversing the above-described procedure, these members 571 and 572 are attached to the extrusion support member 561 and the game nail exchanger 500 to which the insertion support member 571 and the insertion operation member 572 are attached. It can replace | exchange for the action | operation member 562 for extrusion.

  Next, a procedure for replacing the game nail 100 using the game nail exchanger 500 when the game nail 100 provided on the game board 50 is broken will be described with reference to FIGS. FIG. 14 and FIG. 15 are explanatory diagrams of broken game nail push-out operations by the game nail exchanger 500, and FIGS. 16 and 17 are explanatory diagrams of game nail insertion operations by the game nail exchanger 500. 14 to 17, the shapes and arrangements of the game board 50 and the game nail 100 are shown in a simplified manner.

  When the game nail 100 provided on the game board 50 is broken, an extruding support member 561 and an extruding operation member 562 are attached as the game nail changer 500 in order to push out the broken game nail 100. Next, the orientation of the receiving member 513 is adjusted to the orientation corresponding to the position of the broken game nail 100. In this description, as shown in FIG. 14A, a case where the game nail 100 is pushed out by placing the game nail changer 500 so that the base member 511 is positioned above the broken game nail 100. Illustrated. In this case, the inclined surface of the receiving member 513 is such that the distal end side (lower side in FIG. 14A) of the receiving side protruding portion 543 is separated from the operating side protruding portion 542, and the proximal end side (see FIG. 14 (a)) is rotated to align the receiving member 513 in a direction in which the receiving member 513 is located on the side closer to the operating projection 542. After the alignment, the receiving member fixing member 515 is screwed into the base member 511. The receiving member 513 is fixed to the housing.

  After the receiving member 513 is fixed, the push-out support member 561 is positioned so that the front-end portion of the push-out support member 561 slightly enters the through-hole of the front-side protrusion 544 of the game nail exchanger 500. The knob 586 is operated to ensure a wide gap between the pushing support member 561 and the receiving member 513. In this case, the extrusion tip portion 581 of the pushing operation member 562 may protrude from the pushing support member 561 toward the receiving member 513 side, but the pushing tip portion 581 rotates in the direction away from the receiving member 513 side. By rotating the operation member 518 so that the extrusion tip portion 581 does not protrude from the extrusion support member 561 to the receiving member 513 side, breakage of the extrusion tip portion 581 or other parts of the extrusion tip portion 581 can be prevented. It is preferable because it can prevent damage.

  This completes the preparation of the game nail changer 500 in a single state. Next, the game nail changer 500 is gripped by the main body 541, and the portion between the game plate recesses 533, specifically the receiving member 513. The game nail changer 500 is moved so that the game board 50 is positioned between the push-out support member 561 and the distal end portion 585 of the push-out support member 561. In this movement, the game nail changer 500 is arranged so that the center of the receiving member 513 is located on the rear side of the broken game nail 100. After the game nail changer 500 is disposed, the spacer 522 is disposed between the distal end portion 585 of the push-out support member 561 and the game board 50, and the handle 586 of the push-out support member 561 is rotated to receive the member. The pushing support member 561 is advanced to the 513 side, and the game board 50 and the spacer 522 are sandwiched between the tip 585 of the pushing support member 561 and the receiving member 513 (FIG. 14B and FIG. (See FIG. 15 (a)).

  Here, whether or not the spacer 522 is disposed between the distal end portion 585 of the pushing support member 561 and the game board 50 can be selected according to the state of the broken game nail 100. When the broken game nail 100 protrudes from the front surface 51 of the game board 50, the through hole of the spacer 522 is fitted into the protrusion, and the tip of the push-out operating member 562 is rotated into the spacer 522. The operation member 518 is operated to advance the pushing operation member 562 so that the pushing operation member 562 enters the spacer 522, and then the knob 586 of the pushing support member 561 is rotated to rotate the pushing support member. It is preferable that the spacer 522 and the game board 50 be sandwiched between 561 and the receiving member 513. On the other hand, when the tip of the broken game nail 100 is located behind the front surface 51 of the game board 50 and is recessed toward the nail hole 52 side, the spacer 522 is not used and the nail hole 52 is not used. The tip of the pushing operation member 562 may be aligned.

  Thereafter, when the rotation operation member 518 is rotated and the push-out operation member 562 is advanced, the tip of the operation member 562 comes into contact with the broken game nail 100. Further, if the rotation operation member 518 continues to rotate, the rotation operation member 518 comes into contact with the base member 511 as shown in FIG. 14C, and further rotation is impossible. In this state, as shown in FIG. 15 (b), the tip of the pushing operation member 562 advances to a position where it protrudes to the rear surface side of the game board 50, and the broken game nail 100 is pushed out of the game board 50, It enters the hole 613 of the receiving member mounting shaft 514.

  As shown in FIG. 15 (b), the hole 613 of the receiving member mounting shaft 514 communicates with the through hole of the receiving member 513, and the bottom surface of the receiving member 513 is in contact with the rear surface of the game board 50. The inner surface is inclined so that the side is positioned downward. For this reason, after the broken game nail 100 is pushed out from the game board 50, it is easy to enter the back side of the hole 613, and the broken game nail 100 is prevented from falling to the rear side of the game board 50. it can.

  After the broken game nail 100 is pushed out from the game board 50, the rotation operation member 518 is rotated in the reverse direction to retract the push-out operation member 562 toward the direction away from the member 513. After the front end of the pushing operation member 562 comes out of the front surface 51 of the game board 50, the push support member 561 is moved backward by operating the knob 586 of the pushing support member 561 so that the game board 50 and the pushing support member are pushed. In the case where the spacer 522 is disposed between 561 and 561, the spacer 522 is removed. By the above operation, the game nail exchanger 500 can be moved with respect to the game board 50, and the game nail exchanger 500 can be detached from the game board 50.

  The broken game nail 100 does not necessarily have to be pushed out from the front surface 51 side of the game board 50 to the rear surface side, and the pushing operation member 562 is located on the rear surface side of the game board 50 and is received on the front surface 51 side of the game board 50. The game nail exchanger 500 may be arranged in the direction in which the member 513 is located, and the broken game nail 100 may be removed. When the game nail 100 is extremely bent and deformed, it is preferable to remove the game nail 100 from the rear side of the game board 50 to the front side 51 because the nail hole 52 of the game board 50 is less likely to be scraped. is there. The operator can select the push-out direction of the game nail 100 in which the nail hole 52 is not easily cut according to the state of the game nail 100, and the game nail 100 is broken from either side using the game nail changer 500. Can be removed from the game board 50.

  Next, the insertion operation of the game nail 100 will be described. After the broken game nail 100 is removed from the game board 50, the game nail exchange tool 500 is used to insert a new game nail 100. First, the extrusion support member 561 and the extrusion operation member 562 are removed and replaced with an insertion support member 571 and an insertion operation member 572. Thereafter, the orientation adjustment and fixing of the receiving member 513 are performed in the same manner as the push-out operation of the game nail 100 described above. However, if the orientation of the receiving member 513 is fixed by the push-out operation, the insertion operation can also be normally performed in that orientation. Therefore, the adjustment and the fixing operation are not necessarily performed. Thereafter, the knob portion 596 of the insertion support member 571 is positioned so that the distal end portion of the insertion support member 571 slightly enters the through hole of the distal projection portion 544 of the game nail exchanger 500. To secure a wide gap between the insertion support member 571 and the receiving member 513 (see FIG. 16A).

  Then, the main body portion 541 of the base member 511 is gripped, and the game nail changer 500 is moved so that the game board 50 is positioned between the receiving member 513 and the distal end portion 595 of the insertion support member 571. The game nail exchanger 500 is arranged so that the center of the receiving member 513 is located behind the nail hole 52 from which the nail 100 has been removed. After the game nail changer 500 is arranged, the knob 596 is operated so that the insertion support member 571 advances to the receiving member 513 side. After the insertion support member 571 is advanced to the receiving member 513 side, the new game nail 100 is inserted through the insertion support member 571 through the through groove 599 (see FIG. 11C) of the insertion support member 571. Place in the hole. At this time, if the through groove 599 of the insertion support member 571 is opened downward, the game nail 100 easily falls and is difficult to place in the through hole. After adjusting the orientation of the insertion support member 571 so as to open, the game nail 100 is disposed in the through hole (see FIGS. 16B and 17A). Note that a new game nail 100 may be inserted into the through hole of the insertion support member 571 before the game nail changer 500 is aligned with the game board 50. When the insertion support member 571 is rotated with respect to the portion 544, the game nail 100 is prevented from falling by, for example, picking and supporting the front end side of the game nail 100.

  Thereafter, when the turning operation member 518 is turned to advance the insertion actuating member 572, the tip thereof comes into contact with the head 102 of the game nail 100. Further, when the rotation operation member 518 is continuously rotated, as shown in FIG. 16C, the rotation operation member 518 comes into contact with the base member 511, and further rotation is impossible. In this state, as shown in FIG. 17B, the game nail 100 is inserted into the game board 50 to the same depth as the other game nails 100.

  After the game nail 100 is inserted into the game board 50, the turning operation member 518 is rotated in the reverse direction to retract the insertion actuating member 572 away from the member 513. Thereafter, the game nail exchanger 500 is moved so that the newly inserted game nail 100 is pulled out of the insertion support member 571 through the through groove 599. At this time, as shown in FIG. 17B, when the head 102 of the game nail 100 is too close to the end surface on the distal end side hole 597 side of the proximal end side support hole 598 of the insertion support member 571, After operating the knob portion 596 of the insertion support member 571 to move the insertion support member 571 toward the direction approaching the game board 50, the game nail 100 is extracted to the outside of the insertion support member 571. Conversely, when the head 102 of the game nail 100 is separated from the end surface on the distal end side hole 597 side of the proximal end side support hole 598 of the insertion support member 571, the difference is made in the direction away from the game board 50. After moving the support member 571 for insertion, the game nail 100 is extracted outside the support member 571 for insertion.

  After the game nail 100 is removed from the insertion support member 571, the game nail exchanger 500 can be easily moved with respect to the game board 50, and the game nail exchanger 500 can be removed from the game board 50. With the above operation, the exchange of the game nail 100 is completed.

  Next, a method for arranging the game nail changer 500 with respect to the game board 50 will be described with reference to FIG. FIG. 18 is a front view showing a state in which the game nail changer 500 is arranged on the game board 20 from which the center decorative member 22 has been removed.

  The center decoration member 22 provided in the center portion of the game board 20 is preferably attached and fixed from the front side of the game board 20, and is formed in the center portion of the game board 50 when the center decoration member fixed and fixed is removed. The opening 50a is exposed so as to be visible from the front side. By arranging the game board 50 so as to enter the game board recess 533 of the game nail exchanger 500 through the opening 50a, as shown in FIG. The game nail 100 can be exchanged by positioning the central portion of the rotation operation member 518 of the game nail changer 500 with respect to the game nail 100. Therefore, the game nail can be replaced without removing the game board 20 while the pachinko machine 10 is installed in the game hall.

  In this replacement work, it is necessary to adjust the orientation of the receiving member 513. When the base member 511 is positioned above the game nail 100 to be replaced, the receiving member 513 is oriented in the direction exemplified in the above description. To fix. When the base member 511 is located on either the left or right side of the game nail 100 to be exchanged or on the lower side, the base member 511 is rotated 90 degrees or 180 degrees with respect to the angle described above. The receiving member 513 is fixed at the moved position, the actuating member 512 and the nail hole 52 are coaxially positioned, and the inclined surface of the receiving member 513 is in contact with the rear surface of the game board 50 in parallel. Adjust the orientation.

  Note that the game nail exchanger 500 is not necessarily arranged in the direction in which the base member 511 is positioned in any of the up, down, left and right directions with respect to the game nail 100. The base member 511 may be arranged in a direction in which the base member 511 is positioned obliquely with respect to the game nail 100. In this case, the operating member 512 and the nail hole 52 are coaxially positioned in that direction, and the receiving member 513 is provided. The orientation of the receiving member 513 may be adjusted so that the inclined surface of the game plate 50 abuts in parallel with the rear surface of the game board 50. In addition, when the gap between the game nails 100 is narrow, a member having an outer shape as a thin axis is prepared from the above-described distal end side support member 516 and the spacer 522, and the depth of the game plate recess 533 is also set. A larger base member corresponding to the position of the game nail that requires the replacement work may be prepared, or the game board 20 may be removed from the pachinko machine 10 and the game nail changer 500 may be removed from the outer peripheral side of the game board 20. The game board 50 may be disposed in the game board recess 533 to replace the game nail.

  As described above, according to the game nail changer 500, the game nail 100 broken by the pushing operation member 562 is removed from the game board 50, and the new game nail 100 is removed by the insertion operation member 572. Can be inserted and fixed. That is, the game nail changer 500 can be used as a tool suitable for game nail replacement work.

  In addition, an inclined surface as a receiving portion that contacts the game board 50 in the receiving member 513 is formed to be inclined with respect to the moving direction of the operating member 512, and the operating member 512 corresponding to the moving direction of the operating member 512 is formed. It is provided so that it can be rotated about a central axis. For this reason, the lower part 513b located on the side closer to the receiving-side protruding part 543 and the receiving-side protruding part from the lower part 513b by the inclined surface of the receiving member 513 facing the operating-side protruding part 542 side where the game board 50 is arranged A high portion 513a located on the side away from 543 is formed. When the rear surface of the game board 50 is brought into contact with both the lower portion 513b and the higher portion 513a of the receiving member 513, the rear surface of the game board 50 is inclined with respect to the moving direction of the operating member 512. The receiving member 513 comes into contact with the game board 50. Therefore, even if the pushing operation member 562 as the actuating member 512 and the insertion operation member 572 abut against the game nail 100 and move the game nail 100, a large pressing force acts on the rear surface of the game board 50. The actuating member 512 easily advances along the axial direction of the game nail 100 inclined with respect to the game nail 100. Further, by rotating the receiving member 513 to change the direction of the inclined surface, the game nail replacement tool 500 (base member 511) is brought closer to the game nail 100 from the direction in which the operator can easily work and the game nail 100 is moved. Can be replaced. Therefore, even an operator who is unfamiliar with the replacement work of the game nail 100 can replace the game nail 100 relatively easily.

  One end surface of the spacer 522 facing the receiving member 513 is inclined with respect to the through hole of the spacer 522 by the amount of the game nail 100 provided to be inclined with respect to the front surface 51 of the game board 50. The angle coincides with the inclination angle of the inclined surface of the receiving member 513 with respect to the central axis of the operating member 512. And the proximity part (right side part in the lower side end surface of the spacer 522 of FIG. 9) located in the side close to the front end side protrusion part 544, and the isolation | separation part (side part from the front side protrusion part 544 from this proximity part) ( 9 is formed on one end surface of the spacer 522. The left side portion of the lower end surface of the spacer 522 in FIG. When the rear surface of the game board 50 is brought into contact with both the low part and the high part of the receiving member 513, both the proximity part and the separation part of the spacer 522 can contact the front surface 51 of the game board 50. The relative position is set. Therefore, by placing the spacer 522 and the receiving member 513 in close contact with the front surface 51 side and the rear surface side of the game board 50, the game nail is oriented in a direction in which the moving direction of the operation member 512 is inclined along the axial direction of the game nail. It is possible to make it easier to install the exchange tool, and it is possible to efficiently perform the game nail replacement work.

  In the insertion support member 571, the insertion actuation member 572 moves in the moving direction with respect to the distal end side hole 597 and the proximal end side support hole 598 penetratingly formed along the axial direction of the insertion actuation member 572. A through groove 599 is provided on one side that intersects perpendicularly so that a game nail formed to penetrate can be taken out. The insertion support member 571 is attached to the first support portion of the base member 511 so as to be rotatable about the moving direction of the insertion operation member 572 as an axis. For this reason, the periphery of the game nail 100 is supported by the distal end side hole 597 and the proximal end side support hole 598, and the pressing force of the insertion operating member 572 can be applied to the game nail 100 in a stable state. The game nail 100 can be securely inserted and fixed to the game board 50. In addition, after the fixing, the game nail changer 500 can be easily removed from the game board 50 simply by moving the insertion support member 571 to the direction crossing the axial direction of the game nail 100 using the through groove. Can do. Therefore, the game board 50 can be prevented from being damaged when the game nail changer 500 is removed.

  The pushing operation member 562 as the actuating member 512 and the inserting actuating member 572 are supported by the pushing support member 561 or the inserting support member 571 as the leading end side support member 516 on the distal end side along the moving direction. The base end side of the actuating member 512 is supported by the base end side support member 517 at a position spaced apart from the support portion with the operation recess 532 therebetween. For this reason, it is possible to reduce the manufacturing cost by forming separate support members corresponding to the extrusion operation and the insertion operation in a small size, and to set a longer section along the traveling direction in which the operation member 512 is supported. The actuating member 512 is configured to be easily moved along the traveling direction, so that the game nail 100 can be exchanged efficiently.

  The outer shapes of the knob portions 586 and 596 of the extrusion support member 561 and the insertion support member 571 are formed to have a larger diameter than the through-hole of the tip side protruding portion 544 of the base member 511. Therefore, the range until the position where the knobs 586 and 596 come into contact with the tip-side protruding portion 544 is the movable range along the moving direction of the operating member 512 in the push-out support member 561 and the insertion support member 571. The extruding support member 561 and the insertion support member 571 cannot move to the side. Therefore, the operator does not inadvertently operate the extrusion support member 561 or the insertion support member 571 to project the extrusion support member 561 and the insertion support member 571 toward the game board 50 side. Damage to the game board 50 can be prevented.

  Further, the push-out support member 561 and the plug-in support member 561 are inserted at a position separated from the member in which the rotation operation member 518 and the base end side support member 517 that are rotated to advance the operation member 512 are integrated. The operation member 512 is supported by the support member 571. Then, the support member 561 for extrusion and the support member 571 for insertion, and the member in which the base end side support member 517 and the rotation operation member 518 are integrated together are the receiving member 513 from the side away from the receiving member 513. It is attached to the base member 511 by screwing in the direction side approaching. For this reason, when the operation member 512 is advanced by a rotation operation with respect to the rotation operation member 518, the extrusion support member 561 and the insertion support member 571 are rotated by the frictional resistance with the operation member 512, and these support members are supported. There is a possibility that the members 561 and 571 move along the axial direction of the operating member 512. However, as described above, since the extruding support member 561 and the insertion support member 571 are prevented from moving beyond a certain level by the knobs 586 and 596, the game nail 100 can be replaced smoothly. .

  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. In the following description, the same components as those in the above embodiment are denoted by the same reference numerals, description thereof will be omitted, and portions different from those in the above embodiment will be described.

  The receiving member 513 of the game nail exchanger 500 in the above embodiment is formed in an annular shape, and the receiving portion that comes into contact with the game board is formed with a flat inclined surface, but the receiving portion is not necessarily formed in the above shape. There is no need, and a receiving member having another shape having a receiving portion that forms a portion with a different height from the receiving-side protruding portion 543 may be used. For example, as shown in FIGS. 19A and 19B, a receiving member 701 having a shape in which a receiving portion is intermittently formed with respect to the receiving member 513 in the above embodiment may be used. Even in this case, the first receiving portion 701b having a low height position and the second receiving portion 701a having a high height position are intermittently formed on one surface side of the receiving member 513. In addition, the receiving portion of the receiving member 513 does not necessarily have a shape that makes contact with the game board at a part of the plane, and a plurality of protrusions that contact the game board in the form of dots such as hemispherical protrusions are provided. Even if the one flat surface is a flat surface inclined with respect to the advancing direction of the actuating member as the receiving portion where the tip surfaces of the protruding portions are located on one flat surface, the same effect as the receiving member 513 can be obtained.

  A receiving portion that contacts the game board in the receiving members 513 and 701 is a first receiving portion having a low height position in a state where the receiving portion is inclined approximately 5 degrees with respect to the central axis parallel to the moving direction of the operating member 512, and the height Although the case where the second receiving portion having a high position contacts the game board has been described, the center of the operation member 512 is set so as to contact the game board while being inclined at another angle such as approximately 3 degrees or approximately 8 degrees. It may be set to be inclined at another angle with respect to the axis. The receiving members 513 and 701 are provided with a plurality of receiving portions having different height positions along the moving direction of the operating member 512 on both sides of the extension line of the central axis of the operating member 512. It is preferable that the extension line of the central axis of the operating member 512 is positioned at the portion, and this is preferable because one surface of the game board can be stably supported by the receiving member.

  Further, when the receiving member 701 shown in FIG. 19 is brought into contact with the rear side of the game board, the lower portion of the through hole of the receiving member 701 is in close contact with the game board, and the broken game nail 100 is surely secured. The receiving member 701 has a concave portion at the center when viewed in the axial direction of the through hole of the receiving member 701 so that it can be guided to the hole 613 (see FIG. 15B) of the receiving member mounting shaft 514. Is preferred. In addition, as shown in FIG. 19B, the through hole for the fixing screw provided in the receiving member 513 is provided on the position side where the receiving portion of the receiving member is formed at the lowest height, or the height is A fixing screw may be easily used as a mark when adjusting the orientation of the receiving member 513 by providing it at the highest formed position. In this case, the longitudinal groove portion 522a in the spacer 522 is also in the same direction with respect to the rotation center axis of the receiving member 513 and the spacer 522 when the inclined surface of the receiving member 513 and the inclined surface of the spacer 522 are parallel to each other. It is preferable to be provided at a position where

  The adjustment of the orientation of the receiving member 513 is not necessarily performed by a rotation operation while being attached to the base member 511. The receiving member 513 is removed to the operating member 512 side, and the receiving member 513 is removed. The receiving member 513 may be attached to the base member 511 after the orientation of the receiving member 513 is adjusted in this state. The structure of the receiving member 513 is not limited to the mounting and fixing structure in the above embodiment, and other structures may be used.

  The game nail changer 500 in the above embodiment is configured so that the orientation of the receiving member 513 and the spacer 522 is set to be parallel to the front and rear surfaces of the game board, with the longitudinal groove 522a and the fixing screw 523 as marks. In addition, the shape of the part to be the mark is not limited to the above form, and may be any shape such as a point shape, a line shape, a symbol, etc. It may be a mark drawn by painting, printing, or the like. In addition, the number of parts to be used as marks is not necessarily one, and may be a plurality of two or more places that are spaced apart from each other by a predetermined angle around the rotation center axis of the receiving member 513 and the spacer 522. In this case, when the inclined surface of the receiving member 513 and the inclined surface of the spacer 522 are parallel, the mark provided on the position side that is on the same direction side as the rotation center axis of the receiving member 513 and the spacer 522 In order to make it easier to understand, the symbols such as circles and squares are matched, or the numbers on the position side that are the same direction side are the same. It is preferable to do.

  In the game nail exchanging device 500 in the above-described embodiment, a plurality of parts are integrated by a fixing screw, or are integrated by adhesion or joining. However, the part configuration is not necessarily the above-described configuration. The proximal end support member 517 and the rotation operation member 518 may be formed as an integral part, or the rotation operation member 518 and the pushing operation member 562 or the insertion operation member 572 are formed as an integral part. Also good. In this case, the push-out operation member 562 or the plug-in operation member 572 and the rotation operation member 518 are formed separately, and the push-out operation member 562 or the plug-in operation is operated in response to the rotation operation through the handle portion 552. If the member 572 is not interlocked and can be moved straight without rotating, it is preferable because the force in the rotating direction is not transmitted to the game nail. On the other hand, in the case where the rotation operation member 518 and the insertion operation member 572 are formed as an integral part, the rotation operation member 572 always rotates when the insertion operation member 572 advances, but along the rotation direction. A male screw that sets the screw shape of the holding portion of the game nail so that the game nail advances into the game board when the new game nail to be inserted is rotated, that is, the male screw that advances the insertion operating member 572 If the screw shape of the part and the holding part of the game nail are matched with the right screw or the left screw, the game nail can be easily inserted into the game board, and the head of the game nail can be prevented from being damaged. This is preferable because it can improve the appearance.

  Further, when the screw shape of the holding portion of the game nail is set so that the game nail advances into the game board, the insertion actuating member 572 can be easily rotated together with the game nail, In order to prevent scratching, the shape of the head of the game nail (spherical shape in the above embodiment) and the shape of the tip surface of the insertion actuating member 572 that contacts the game nail may be formed substantially the same. Scratching and scraping can be suppressed by dispersion of the pressure at the contact portion. In addition, the peripheral surface of the insertion actuating member 572 is supported by a bearing such as a ball bearing so that the insertion actuating member 572 easily rotates with the rotation of the game nail. At least of the opposing surfaces of the fixed operation member 519 and the insertion operation member 572 so that the contact portion between the fixed operation member 519 and the insertion operation member 572 is only the central shaft portion of the insertion operation member 572. For example, the one side may have a conical shape or the like, and in this case as well, it is preferable because friction between the insertion actuating member 572 and the head of the game nail can be suppressed.

  In addition, the spacer 522 is not necessarily provided as a separate component separated from the extrusion support member 561, and a protrusion protruding in a columnar shape around the through hole on the surface side of the spacer that contacts the extrusion support member. A hole having a size capable of press-fitting the protrusion is formed on the extrusion support member side, and the spacer is press-fitted and fixed to the extrusion support member so as to be rotatable around the through hole. It is good also as a structure. The spacer 522 may be configured so as to be integrated with the extrusion support member 561. For example, an adhesive is applied to a contact portion between the spacer 522 and the extrusion support member 561 so that the spacer 522 is supported by the extrusion support member 561. May be joined to each other. In this case, it is preferable to join the spacer 522 to the extrusion support member 561 with an adhesive that forms a viscous adhesive layer so that the spacer 522 can be integrated with the support member 561 even in a small amount. When the surface and the inclined surface of the spacer 522 are deviated, the spacer 522 is moved or rotated with respect to the extrusion support member 561 so that they are likely to approach parallel to facilitate the game nail replacement operation. Can do.

  With respect to the spacer 522 in the above embodiment, spacers having different lengths along the moving direction of the actuating member may be prepared, and one of the spacers may be selectively used to push out the game nail. For example, a spacer having a plurality of types of lengths such as 3 mm, 8 mm, and 12 mm as the length of the central axis portion along the moving direction of the operating member may be prepared. While the members of the game nail changer 500 other than the spacers are made common, spacers suitable for game boards having different thicknesses can be used, and further, the thickness cannot be accommodated only by adjusting the position of the extrusion support member 561. The game nail push-out operation can be stably performed on the other game board using the game nail changer 500.

  In the insertion support member 571 of the game nail exchanger 500 in the above embodiment, a through groove 599 used for extracting the game nail after insertion is crossed in the moving direction of the insertion operation member 572. However, it is not always necessary to provide it only on one side, and it may be formed on both sides intersecting the moving direction, or on three directions separated by a certain angle with the moving direction as the central axis. Further, the width of the long groove portion 602 of the through groove 599 may be set to be substantially the same as the distal end side hole 597 of the insertion support member 571. Further, the opening 601 of the through groove 599 is not necessarily formed in a circular shape in a side view, and may have another shape such as a semicircular shape or a substantially rectangular shape as long as the head of the game nail can pass therethrough. .

  In the above-described embodiment, a portion where the rotation operation such as the handle portion 552 and the fixed operation portion 553 of the rotation operation member 518 of the game nail changer 500 is performed has a recess on the outer peripheral surface to facilitate the rotation operation. It may be provided, or the surface may be provided with a streak-like or mesh-like slip stopper by rolling, or may be formed easily by providing a bar-like portion protruding on one or both sides in the outer peripheral direction.

  With respect to the receiving portion fixing member 515 of the game nail changer 500 in the above embodiment, as shown in FIG. 20, a through hole is formed in the central portion of the receiving portion fixing member 711 along the central axis of the operating member 512. You may provide the positioning operation member 712 formed so that the thin shaft part 712a might protrude from the receiving member 513. FIG. When aligning the receiving member 513, the center position of the receiving member 513 can be accurately arranged with respect to the nail hole 52 by inserting the thin shaft portion 712 a of the positioning operation member 712 into the nail hole 52. it can. The positioning operation member 712 needs to be able to be extracted from the nail hole 52 before the game nail 100 is pushed out and inserted after the receiving member 513 is positioned. For example, the positioning operation member 712 penetrates through the side where the receiving member 513 is provided. A shaft that can be inserted into the nail hole by protruding from the contact portion that contacts the one surface of the game board 50 by the receiving member 513 by being inserted from the opposite side of the hole and the through hole to the side where the operation member 512 is located. It is good also as a positioning operation member which has.

  In the above-described embodiment, the operator rotates the handle portion 552 by manual operation with respect to the rotation operation member 518 and advances and retracts the operation member 512. However, the rotation operation member 518 is not necessarily rotated by manual operation. There is no need to drive the driving member 512, which is electrically operated, such as a motor, and connected to the turning operation member 518 by a drive transmission mechanism such as a gear. That is, the rotation operation member 518 is not limited to a member operated by a direct manual operation by an operator, and may be configured to operate indirectly by an operation on the driving unit.

  The game nail exchanging device 500 in the above embodiment can be used for exchanging the game nails 100, 150 held in the nail holes 52, 202, 302 provided in the game boards 50, 200, 300 described in the above embodiment. In addition, the present invention is not limited to the above-described game board and game nail, but can be used for other forms of game boards and game nails, and can be used as a nail for fixing a windmill or the like to the game board. It can also be used. Further, it is not always necessary to use the game nail exchanging device 500 for exchanging game nails provided on the game board made of synthetic resin, and it may be used for game nails provided on a wooden game board. In this case, the nail hole in the wooden game board must also be formed to penetrate from the front side to the rear side at the inner diameter of the portion where the game nail is held. In addition, it is not always necessary to perform the push-out operation and the insertion operation of the broken game nail using one game nail changer 500. Two game nail changers 500 are prepared, and each operation is performed separately. It may be implemented with the changer 500, or the game nail changer 500 is used only for pushing out the game nail, and the game nail is used only for any operation such as using other tools for the game nail insertion operation. It is good also as performing with the exchange tool 500. FIG.

  In contrast to the game nail exchanger 500 in the above embodiment, for example, as shown in FIG. 21, a game nail exchanger 800 having a base member 801 having a different shape may be used. FIG. 21 is a side view showing a game nail exchanger 800 according to another embodiment.

  The game nail changer 800 is different from the game nail changer 500 in the above embodiment shown in FIG. Specifically, in the above-described embodiment, the side portion that is separated from the operation member 512 is deleted from the portion where the operation-side protrusion 542 is formed, and the outer shape portion that forms the elongated hole 534 is deleted from the main body portion 541. The shape is made.

  As shown in FIG. 21, the base member 801 of the game nail exchanging device 800 has a distal end side projecting portion 544 and a proximal end side projecting portion 545 on one side with respect to the operating member 512 across the space of the operation recessed portion 532. (The right side of FIG. 21) is a continuous shape. That is, on one side of the actuating member 512, the distal end side protruding portion 544 and the proximal end side protruding portion 545 are connected by the main body portion 802 of the base member 801, and have a U-shaped portion in side view. A lower portion corresponding to the distal end side in the moving direction of the operating member 512 in the main body 802 of the base member 801 is closer to a direction away from the central axis of the operating member 512 than an upper portion corresponding to the proximal end side in the moving direction. It has a shape that protrudes and continues up and down on the protruding tip side. For this reason, the base member 801 of the game nail exchanger 800 has a shape having a U-shaped portion in a side view with a recessed portion having a deeper depth than the upper portion where the operation recessed portion 532 is formed as a game plate recessed portion 533. Has been. Compared with the base member 511 in the above-described embodiment, the base member 801 is provided only at the part connecting the two protrusions 544 and 545 constituting the operation-side protrusion, the receiving-side protrusion 543, and the protrusions 543 to 545. As a result, the weight of the base member 511 can be reduced, and the game nail changer 800 can be formed in a small size by limiting the outer shape to the minimum required functional part and attached to the game board. The possibility of causing the game nail exchanger 800 to collide with peripheral parts or the like can be minimized. In terms of operability, it is possible to stably move by placing a finger on the U-shaped inner surface by grasping the main body portion 802 that is continuous in the vertical direction corresponding to the bottom side portion of the dent portion 533 for game board. It is possible to achieve high operability by reducing the weight with the minimum necessary shape.

  The width W and the depth D of the game board recess 533 must be formed wider than the total of the thickness of the game board, the amount of protrusion of the game nail to the front side, and the thickness of the receiving member 513. For example, when the thickness of the game board is about 8 mm, the amount of protrusion of the game nail to the front side is about 18.5 mm, and the thickness of the receiving member 513 is about 8 mm, at least about 35 mm is necessary, and the thickness of 5 mm or more It is preferable to set it to about 40 mm or more with a margin. Further, when a thick game board is used and when the amount of protrusion of the game nail to the front side is set to be large, the width W of the game board recess 533 is set wide according to the increased amount.

  It is possible to replace the game nail attached to the game board so that the depth D of the dent part 533 for the game board ensures a long continuous range in the depth direction side (the right side in FIG. 21) without reducing the width W. This is preferable because the range can be expanded. For example, the depth D of the game board recess 533 is set within a range of about 60 mm to about 150 mm with respect to the central axis of the operating member 512 as a length in the depth direction side where the width dimension does not decrease. Is preferable, and is preferably set within a range of approximately 70 mm to approximately 100 mm. As the depth D of the game board recess 533 is longer, the outer shape of the base members 501 and 801 is separated from the central axis of the operation member 512, and the insertion operation to the opening 50a (see FIG. 18) of the center decoration member is performed. In order to make it difficult or impossible, it is preferable that the depth D of the game board recess 533 is set to the above-described size not to be too long.

  You may provide the position adjustment means which can adjust the insertion position of the game nail in the said embodiment. For example, the adjustment spacer 811 may be provided as a movement restricting member that restricts the movement of the operating member 512 toward the distal end side in the movement direction (the lower side in FIG. 21). As shown in FIG. 21, the adjustment spacer 811 is disposed between the rotation operation member 518 and the end surface of the base member 801 where the rotation operation member 518 comes into contact, and is slightly smaller than the outer shape of the base end side support member 517. And an annular metal member having a large inner diameter. The thickness of the adjustment spacer 811 along the central axis of the operation member 512 restricts the movement of the operation member 512 toward the distal end side in the insertion direction (the lower side in FIG. 21). With this adjustment spacer 811, the amount of protrusion of the game nail to the front side can be increased in the insertion operation, and the adjustment spacer 811 corresponding to the change in the thickness of the game board can be provided to the game boards having different thicknesses. It can be set as a corresponding game nail changer. In addition, the screwing amount of the fixing operation member 519 with respect to the rotation operation member 518 may be adjusted to serve as a position adjustment unit. The fixing operation member 519 is not completely screwed into one end side of the rotation operation member 518. Providing a margin can also limit the movement of the actuating member 512 toward the tip side. Even if the relative position between the base end side support member 517 and the rotation operation member 518 is changed along the central axis of the operation member 512, the insertion position of the game nail can be changed as the position adjusting means. The position can also be set by adjusting the relative position along the axial direction of the rotation operation member 518 with respect to the base end side support member 517 after the fixing screw 521 is loosened.

  Instead of at least one of the extrusion support member 561 and the insertion support member 571 in the above embodiment, for example, as shown in FIGS. 22 (a) and 22 (b), the extrusion support having a different tip shape is used. At least one of the member 821 and the insertion support member 831 may be a component of the game nail exchanger. FIG. 22A is a side view of the support member 821 for extrusion in another embodiment, and FIG. 22B is a side view of the support member 831 for insertion in another embodiment. And FIG.22 (d) is explanatory drawing which shows the use condition of each support member 821,831, and FIG.22 (e) is a side view of the support member 839 for insertion in other embodiment.

  The extrusion support member 821 and the insertion support member 831 have tip portions 822 and 832 that are longer than the extrusion support member 561 and the insertion support member 571 in the above embodiment, as shown in FIG. The length of the game board 50 is set between the receiving member 513 and the receiving member 513. That is, as shown in FIG. 22A, the extrusion support member 821 has a male screw portion 584 and a knob portion 586 that have the same shape as in the above embodiment, and the length L1 of the tip portion 822 is the tip in the above embodiment. The length is set substantially equal to the length obtained by adding the length of the spacer 522 to the portion 585.

  The shape of the distal end portion 822 of the pushing support member 821 is a substantially spherical shape in which the portion that contacts the game board on the distal end side where the receiving member 513 is located is an arc shape when viewed from the side, and the central portion bulges most toward the receiving member 513 It is formed in (substantially hemispherical). As shown in FIG. 22 (d), the tip end portion 822 of the pushing support member 821 has a through hole in the center portion and is in a position close to the center of the receiving member 513 that contacts the back surface of the game board 50 in an annular shape. It is set to contact the game board 50. For this reason, when the tip of the pushing support member 821 is advanced toward the game board 50, a force acts near the center of the receiving member 513, and the gaming board 50 is placed between the receiving member 513 and the pushing support member 821. Can be easily and accurately executed.

  The length L1 from the knob 586 to the tip of the tip 822 in the push-out support member 821 is such that the push-out support member is sandwiched between the game plate 50 to which the game nail to be replaced is fixed and the receiving member 513. 821 and the receiving member 513 are both set to a length that can contact the game board 50. The length L1 from the knob 586 to the tip of the tip 822 may be set according to the thickness of the game board to which the game nail to be replaced is fixed, and corresponds to a plurality of types of game boards having different thicknesses. In such a case, the length L1 from the knob 586 to the tip of the tip 822 may be determined based on the game board formed to be thinnest.

  Also for the insertion support member 831, as shown in FIG. 22B, the male screw portion 594 and the knob portion 596 have the same shape as in the above embodiment, and the length of the tip portion 832 is the tip portion in the above embodiment. It is set longer than 595. The length L2 from the knob 596 to the tip of the tip 595 of the support member 831 for insertion is the support member 831 for insertion in the state where the game board 50 to which the game nail to be replaced is fixed is sandwiched in the front and rear. And the receiving member 513 are set to lengths that allow the game board 50 to be in contact with each other.

  As for the shape of the distal end portion 832 of the insertion support member 831, the portion that contacts the game board on the distal end side where the receiving member 513 is located is arcuate in a side view, and the central portion bulges most toward the receiving member 513 side. It is formed in a substantially spherical shape (substantially hemispherical shape). As shown in FIG. 22D, the distal end portion 832 of the insertion support member 831 is located at a position close to the central portion where the receiving member 153 contacts the back surface of the game board 50 in an annular shape. The front end is set to abut, and the operation of sandwiching the game board 50 between the receiving member 513 and the insertion support member 831 can be easily and accurately performed.

  Here, an operation of sandwiching the game board 50 between the receiving member 513, the extruding support member 821 and the inserting support member 831 will be described with reference to FIGS. 22 (c) and 22 (d). 22 (c) and 22 (d) show a state in which the gaming board 50 cut in the longitudinal direction is viewed from the side, and after adjusting the orientation of the receiving member 513, the support member 821 for extrusion (or the difference) The operation process of rotating the insertion support member 831) to sandwich the game board 50 between the receiving member 513 and the extrusion support member 821 (or the insertion support member 831) and the state after the operation are shown. Yes.

  For example, an operation of attaching the insertion support member 831 to the game nail changer 500 and sandwiching the game board 50 between the insertion support member 831 and the receiving member 513 will be described. First, as shown in FIG. 22 (c), the distal end portion 832 of the insertion support member 831 is brought into contact with the game board 50 while being matched with the nail hole into which the game nail formed on the game board 50 is inserted. Let In this case, since the center portion of the distal end portion 832 of the insertion support member 831 protrudes most toward the receiving member 513, the protruding end portion tapered toward the distal end side may be aligned with the nail hole. The hole can be easily confirmed, and the center of the distal end portion 832 of the insertion support member 831 can be easily aligned. Further, even if the inclination angle of the game nail changer 500 is changed after the insertion support member 831 is aligned, the positional deviation between the central axis of the tapered tip 832 and the nail hole is suppressed to a small extent. Can do. Therefore, the inclination angle of the game nail changer 500 can be easily adjusted.

  After the positioning of the distal end portion 832 of the insertion support member 831, the insertion support member 831 is rotated to the direction side close to the member 513 side (arrow direction side in FIG. 22C). If this rotation operation is continued, a part of the receiving member 513 comes into contact with the back surface of the game board 50, and if the rotation operation is continued further, along the curved surface shape of the contact portion of the insertion support member 831. While the entire game nail changer 500 is gradually inclined, the gap between the surface of the receiving member 513 facing the game board 50 and the back surface of the game board 50 is reduced. Further, by rotating the insertion support member 831, as shown in FIG. 22 (d), there is no gap between the surface of the receiving member 513 facing the game board 50 and the back surface of the game board 50. The game nail exchanging device 500 is arranged at an appropriate inclination angle in which the insertion direction of the game nail coincides with the direction in which the distal end portion 832 of the support member 831 continues and the penetration direction of the nail hole coincide.

  In the middle of the inclination of the game nail exchanging device 500, a position where the portion of the distal end portion 832 of the insertion support member 831 that contacts the game board 50 is separated from the portion of the receiving member 513 that contacts the game board 50. It is preferable that the center portion of the distal end portion 832 of the insertion support member 831 protrudes most toward the receiving member 513 side. In the case of this shape, the game nail exchanger 500 can be easily shifted to an inclined state around the vicinity of the center of the distal end portion 832 of the insertion support member 831, and the game nail exchanger 500 is moved to an appropriate inclination angle side. Can be easily tilted. In addition, a part of the outer periphery of the annular receiving member 513 is in contact with the back side of the game board 50, whereas a force acts near the center of the receiving member 513 on the front side of the game board 50, so The turning operation of the support member 831 makes it easy for the turning force to act on the direction in which the entire game nail exchanger 500 is inclined at an appropriate inclination angle. For this reason, the rotation operation of the insertion support member 831 can be easily performed with a small force until the gap between the surface of the receiving member 513 facing the game board 50 and the back surface of the game board 50 is eliminated. The game nail exchanger 500 can be accurately arranged in a state in which it can be inserted into the nail hole to be operated. When the insertion support member 831 is rotated, the difference between the game board 50 and the insertion support member 831 is closer to the rotation center of the insertion support member 831. The rotational resistance torque due to the frictional force caused by the contact between the insertion support member 831 and the game board 50 is small, and the insertion support member 831 can be easily rotated. Furthermore, even if a damage is caused by friction between the insertion support member 831 and the game board 50, the damage is formed near the base of the game nail. It is possible to prevent the visibility of the decorative part provided on the back side of the game board 50 visible through the decorative part or the game board 50 applied in this way from being lowered. The shape of the distal end portion 822 of the extrusion support member 821 is also the most protruding shape toward the receiving member 513 side, and therefore has the same effect as the pinching operation of the game board 50 in the insertion support member 831. It can be.

  The tip shapes of the tip portions 822 and 832 of the extrusion support member 821 and the insertion support member 831 are not limited to a substantially spherical shape, and may be other shapes such as a curved shape in which the central portion bulges toward the receiving member 513. . For example, the tip shapes of the tip portions 822 and 832 may be formed in a curved shape combining a plurality of curvature radii. Further, as the distal end shape of the distal end portion of the extrusion support member and the insertion support member, the central portion of the distal end portion 832 protrudes toward the receiving member 513 with respect to a plane perpendicular to the direction in which the distal end portion 832 continues, and the peripheral portion It is good also as a shape which has the inclined surface which inclined linearly by side view. The inclined surface may be a substantially frustoconical shape with a through hole formed in the central portion with respect to the substantially conical shape, or a substantially polygonal frustum shape in which a through hole is formed in the central portion with respect to the substantially polygonal pyramid. In the case of a substantially polygonal pyramid, a regular hexagonal frustum or a regular octagonal frustum, such as a regular polygonal frustum having at least five or more corners, a support member for extrusion and a support member for insertion This is preferable in that the rotation operation can be executed smoothly.

  For example, as shown in FIG. 22E, the insertion support member 839 in which the distal end surface shape of the distal end portion 832 is different from the insertion support member 831 is perpendicular to the direction in which the distal end portion 832 continues. The inclined surface inclined at an angle A1 with respect to the plane may have a substantially conical tip surface 839a formed over the entire circumference around the central axis of the tip portion 832. In this case, the angle A1 coincides with the angle at which the nail hole is inclined with respect to the thickness direction of the game board 50, that is, the inclination angle at which the game nail is inclined with respect to the direction toward the front surface of the game board 50. Or it is preferable to set it to an angle larger than the inclination angle. The above-described effect can be achieved by bringing the vicinity of the center of the front end surface 839a of the insertion support member 839 into contact with the front surface of the game board. Further, an angle A1 at which the front end surface is inclined with respect to a plane perpendicular to the direction in which the front end portion 832 is continuous is an inclination angle (for example, approximately 5 degrees) at which the game nail is inclined with respect to the direction toward the front surface of the game board 50. ), The operational feeling of the insertion support member 831 and the game in the situation where the game nail changer 500 is arranged at an appropriate inclination angle and when the insertion support member 831 is rotated. The feeling of supporting the nail changer 500 is different. Therefore, the game nail exchanger 500 can be more easily arranged at an appropriate inclination angle in the operation of sandwiching the game board 50.

  As shown in FIG. 22B, the through-groove 833 of the insertion support member 831 has a length L3 from the distal end side of the distal end portion 832 to the opening portion 834 formed larger than the outer shape of the head of the game nail. It is set shorter than the amount of projection of the game nail fixed to the game board to the front side. For example, when the amount of protrusion of the game nail to the front side is set to about 18 mm, the length L3 to the opening 834 may be set to about 16 mm or the like as a length shorter than this amount of protrusion. Furthermore, it may be set to be sufficiently shorter than the protruding amount on the front side of the game nail, for example, 3 mm or more. After the game nail is fixed to the game board, it is necessary to pull out the game nail through the through groove 833. Therefore, the length L3 to the opening 834 in the through groove 833 is set smaller than the protrusion amount of the game nail to the front side. Is done. When inserting the game nail, the game nail is supported in a state where the head of the game nail is supported at a portion on the inlet side (upper side of FIG. 22 (b)) where the through groove 833 is not formed in the base side support hole 835. The game nail is advanced into the game board 50, so that the head of the game nail does not move toward the through groove 833, and the game nail can be stably advanced into the game board 50.

  The extrusion support member 821 and the insertion support member 831 may be formed of a metal material, but are preferably formed of a resin material whose surface hardness is softer than the surface hardness of the game board 50, or It is preferable to perform a surface treatment or the like in which a surface portion softer than the surface hardness of the game board 50 is formed on at least the front end side surfaces of the front end portions 822 and 832. For example, when the game board 50 is made of polycarbonate or acrylic, a material including polypropylene or elastomer having a softer surface hardness than the material of the game board 50 is used, or at least the tips 822 and 832 of the game board 50 are made of the soft material. Preferably, the tip is formed. Scratches can be suppressed when the distal ends 822 and 832 of the extrusion support member 821 and the insertion support member 831 abut against the surface of the game board 50 and are rubbed.

  In place of the insertion support member 571 in the above embodiment, as shown in FIG. 23, the base end side support hole 842 is in the range where the through groove 599 is formed and is closer to the long groove portion 602 than the circular opening 601. It is good also as the supporting member 841 for insertion of the continuous shape. FIG. 23A is a side view of an insertion support member 841 in another embodiment, FIG. 23B is a partial cross-sectional view of the insertion support member 841, and FIG. It is explanatory drawing which shows the use condition of the support member 841 for insertion. 23 (b) and 23 (c) also show the game nail, and FIG. 23 (c) schematically shows the insertion actuating member 572.

  The proximal-side support hole 842 is formed with an inner diameter slightly larger than the head of the game nail, and is closer to the distal end side of the game nail in the insertion direction than the circular opening 601 in the through groove 599 (lower side in FIG. 23A). Is continuous. The long groove portion 602 that is continuous with the opening 601 in the through groove 599 is a portion that is thinner than the head of the game nail and thicker than the shaft portion. For example, the long groove portion 602 has a width approximately equal to that of the shaft portion of the game nail. When it is .85 mm, it is set to about 3 mm. The opening 601 is a part formed larger than the head of the game nail, and the size of the opening 601 is set to an inner diameter of about 5 mm when the head of the game nail is about 4.3 mm, for example. ing.

  A distal end side hole 843 having a diameter smaller than that of the proximal end side support hole 842 and allowing insertion of a shaft portion of the game nail is continuous to the side opposite to the entrance of the proximal end side support hole 842 (lower side in FIG. 23A). ing. The head of the game nail is arranged in the base end side support hole 842 through the through groove 599, and the game nail is supported by the insertion support member 841 by arranging the shaft portion of the game nail in the tip end side hole 843. The game nail can be inserted.

  The length X1 of the section continuing from the opening 601 to the distal end side in the game nail insertion direction in the base end support hole 842 is determined when the amount of game nail inserted into the front surface of the game board is the insertion amount S. , Longer than the insertion amount S. Therefore, as shown in FIG. 23 (b), with the head of the game nail positioned on the long groove 602 side from the opening 601, the game nail is brought into contact with the game board by bringing the tip of the game nail into contact with the game board. Even if the game nail is inserted into the game board, the head of the game nail can be sufficiently inserted into the game board by moving within the range where the base end side support hole 842 is formed. For example, when the insertion amount S is approximately 5 mm, the length X1 of the section continuing from the opening 601 to the distal end side in the game nail insertion direction at the proximal support hole 842 is approximately 10 mm, which is larger than the insertion amount S. Is set. With this setting, as shown in FIG. 23C, the insertion actuating member 572 is advanced while the opening 601 of the through groove 599 is closed at the tip of the insert actuating member 572. The operation of inserting the nail can be performed, and the game nail can be prevented from dropping through the through groove 599.

  Here, the amount of the game nail inserted into the front surface of the game board is determined from the insertion amount S as the length X1 of the section continuing from the opening 601 to the distal end side of the game nail in the base end side support hole 842. A small length may be set. Even in this case, as shown in FIG. 23C, a state in which the opening 601 of the through groove 599 is closed at the distal end portion of the insertion operation member 572 can be formed, and the insertion support member 571 can be formed. It is possible to prevent the game nail from falling after the game nail is arranged on the inside.

  The length X2 from the opening 601 of the through-groove 599 to the distal end surface in the insertion direction of the game nail at the distal end of the insertion support member 841 is determined through the through-groove 599 after the game nail is fixed to the game board. It is set shorter than the amount of projection of the game nail fixed to the game board to the front side so that the nail can be taken out.

  In the first embodiment, the nail hole 52 provided in the game board 50 has a circular cross section. However, it is not always necessary to have a circular cross section. You may form in other shapes, such as a shape. Further, the nail hole 52 is not necessarily configured as a through hole, and may be configured as a non-through hole in which only the front side of the game board 50 is opened and the rear side (back side) is closed. However, when the game nail 100 breaks, the hole of the inner diameter that holds the holding portion 111 penetrates to the back side so that the game nail 100 can be pushed out and pulled out. Preferably it is. As a result, when the game nail 100 breaks, the inner surface of the nail hole 52 is less likely to be shaved than when the remaining portion of the game nail 100 is pulled out to the surface side, and the game nail 100 when the game nail 100 is replaced with a new game nail is obtained. The holding power against pulling out can be made high.

  Here, the center decoration member 22 in the first embodiment is provided with an opening in the game board 50 and is fixed by screwing from the front surface 51 side of the game board 50, etc., from the front side with respect to the opening of the game board 50. It is preferable to be fixed removably. When the broken game nail 100 is pushed out and pulled out to the back side of the game board 50 as described above, a part of the game nail 100 is disposed before and after the game board 50 through the opening of the game board 50. Special tools can be arranged. Specifically, a shaft-like member that can move so as to protrude toward the part located on the back side is provided at a part located on the front side of the tool, and the game nail 100 broken by the member is attached to the game board 50. Extrude from the front side. A game ball path is provided in the game nail 100 provided on or near the start winning opening 25 or in the center decoration member 22 and guided from the upstream side away from the starting winning opening 25 to the portion directly above the starting winning opening 25. In many cases, game nails 100 having a high contact frequency of game balls and having a high influence on the outcome of a game such as a prize are arranged around the center decoration member 22 such as an entrance portion of the passage. The nail needs to be arranged at a specified angle at a specified position so that the game ball is paid out to the player as a prize ball as designed. This type of game nail 100 is highly likely to break, and even if it is a transparent game board with respect to the game nail 100, the front 51 of the game board 50 can be obtained even if a small dedicated tool is provided by providing an opening in the game board 50. When the game nail 100 is pushed out from the side to the back side and replaced with a new game nail, it is possible to maintain a high holding force against the withdrawal of the game nail 100.

  In the third embodiment, the center decoration member 22 may be configured to attach the game nail 150 in the third embodiment to the game board 300 fixed from the front surface 301 side through the opening of the game board 300. In this case, The constricted portion 152 as a hard portion has a smaller cross-sectional area than the contact portion 113, and the game nail 150 is easily broken at the central portion of the constricted portion 152 or at a portion close to the holding portion 111 having a high bending stress. A part on the tip side of the nail 150 tends to remain in the thickness range of the game board 300, that is, in the nail hole 302. When the remaining game nail 150 is pushed out to the back side of the game board 300 and a new game nail 150 is inserted, when the broken game nail 150 is pushed out, the front surface 301 side of the game board 300 on the inner surface of the nail hole 302 remains. Since the game nail 150 is not rubbed at all, the portion is not scraped off, and it is possible to easily increase the holding force against the extraction of the game nail 100 when the game nail is replaced with a new one.

  In each of the above embodiments, the holding portion 111 is configured by two thread shapes protruding toward the outer peripheral surface side, but it is not always necessary to have two thread shapes, and may be one or three or more, If the shape is such that the pulling force is obtained, the cross-sectional shape is not twisted along the axial direction, and a net shape or a striped knurled shape or a large number of protrusions parallel to the axial direction are provided in the circumferential direction. It is good also as a holding | maintenance part which has the cross-sectional shape by which the unevenness | corrugation was provided in the surface.

  In each of the above embodiments, the holding portion 111 and the constricted portion 152 as the hard portion are provided so as to protrude approximately 0.3 mm forward from the front surfaces 51, 201, 301 of the game boards 50, 200, 300. However, it is not always necessary to set the protrusion amount, but it is preferably within a range of about 0.1 mm to 0.5 mm, and preferably within a range of about 0.2 mm to about 0.4 mm. It is. Further, when the game nails 100 and 150 are attached to the game boards 50, 200, and 300 while being tilted upward, the protruding amount of the hard portion is minimized at the upper portion, and thus the minimum portion is the above. It is preferable to set the protruding amount.

  In each of the above embodiments, the holding portion 111 and the constricted portion 152 as the hard portion are formed harder than the contact portion by plastic deformation due to processing when forming the outer shape, but are not necessarily formed hard when processing the shape. However, the hard portion may be formed by other methods. For example, the surface may be hardened by a process such as shot peening in which a small-diameter iron ball is collided with the surface to harden the surface, or is positioned forward and backward with respect to the front surface of the game board in the shaft portion of the game nail The surface may be hardened by forming a metal film or layer harder than brass as a base material by vapor deposition or the like. The boundary between the holding portion 111 or the constricted portion 152 as the hard portion and the portion that is not the hard portion can be formed so that the ridge line clearly appears, and the surface color can be changed so that it can be confirmed at a glance. It is preferable that the boundary line can be confirmed by differentiating the position of the boundary between the edge portions of the nail holes 52, 202, 302 on the front side of the game boards 50, 200, 300 and the boundary line. It can be easily confirmed, and the appearance can be improved in quality by overlapping the edge portion with the boundary line. The front surface of the game board while combining the inner diameter of the nail holes 52, 202, 302 and the outer diameter of the holding portion 111 so that the tightening allowance or pullout force is different from the tightening allowance or pullout force in each of the above embodiments. A part of the hard portion may be slightly protruded to the side, and even in this case, the adjustment operation of the game nail on the resin game board can be suitably performed. In addition, a colored sheet-like decorative board (cell board) is placed on the front of the resin game board, or an opaque resin game board is placed inside the nail hole from the front side of the game board. The tip of the inserted game nail may be configured to be invisible, and in this case, it is possible to make it easier to visually recognize a part of the holding portion 111 protruding as a hard portion protruding from the front surface of the game board. It is preferable.

  In each of the above-described embodiments, a part of the holding portion 111 or the constricted portion 152 as the hard portion protrudes forward from the front surface of the game board 50, 200, 300, but this configuration is not necessarily required. By setting the above-described tightening allowance or pull-out force while placing the hard portion completely in the nail holes 52, 202, 302, the behavior of the game ball on the resin game board is suitable. This is preferable.

  The specific part 61 where the specific game nail 100a in each of the above embodiments is provided is not limited to the part in the above embodiment, and may be another part. In this case, the angle of the game nail may be adjusted with a large inclination or a game ball. It is preferable to set, as the specific part, a part that frequently contacts or a part where the game ball contacts at high speed. In addition, regarding the engagement structure in which the game nail and the nail hole, which are the combination of the game nail 100, 150 and the nail hole 52, 202, 302 in each of the above-described embodiments, are engaged with each other as described in the above-described embodiments. May be applied to all game nails provided in one pachinko machine, or two types of engagement structures may be applied to one pachinko machine divided into specific game nails 100a and general game nails 100b. In addition, three or more types of engagement structures may be applied to one pachinko machine.

  You may implement this invention in the pachinko machine etc. of a type different from the said embodiment. For example, it may be implemented as a pachinko machine in which a big hit expectation value is increased until a big hit state is generated several times (for example, two times or three times) including that. Moreover, after a jackpot symbol is displayed, it may be implemented as a pachinko machine that enters a special gaming state on the condition that a ball wins a predetermined area. Moreover, you may employ | adopt as what is called a normal machine without lottery functions, such as jackpot. You may implement as a pachinko machine which will be in a special game state when a ball enters a predetermined winning slot. Moreover, you may implement in the enclosed pachinko machine with which a ball | bowl circulates. Further, in addition to the pachinko machine, the present invention may be implemented as various game machines such as an arrangement ball type pachinko machine and a sparrow ball.

  Hereinafter, the features of the invention group extracted from the above-described embodiment will be described while showing effects and the like as necessary. In the following, for easy understanding, the corresponding configuration in each of the above embodiments is appropriately shown in parentheses, but is not limited to the specific configuration shown in parentheses. In addition, the meanings and examples of terms described in each feature may be applied as the meanings and examples of terms described in other features described in the same wording.

<Feature A group>
Conventionally, there is a pachinko machine as a representative example of a gaming machine. The pachinko machine has, for example, a game board that forms a game area in which game balls flow down. In the game area, a game ball is paid out when the game ball wins, and the game ball is guided to the prize opening. A number of game nails are provided that form a passage and a passage that leads to the out-out opening without winning the winning opening. A large number of game nails are driven and fixed to a game board that forms the outer shape of the game board. As this game board, wood such as veneer has been used in the past, and in recent years, resin board materials or molded products are used. Has also been used. In particular, by using a game board made of transparent resin, it is possible to make a decorative member such as a light emitter provided on the back side of the game board visible to the player, and to expand the installation area of the decorative parts more than before. (For example, refer to JP2008-161638).

  However, game nails driven into resin game boards have different feels to adjust game nails compared to game nails driven into wooden game boards and cannot be adjusted as usual. If you adjust it too much, there is a problem that the game nail breaks.

<Feature A1>
A resin game board (game board 50, 200, 300) from which the game ball flows down the front side, and a game nail (game nail 100, 150) provided so as to protrude forward with the front side of the game board facing. In a gaming machine (pachinko machine 10) equipped with
The game nail continues from the front surface of the game board to the back surface side of the game board with a head (head 102) provided at a protruding end protruding to the front side and an outer diameter smaller than the outer diameter of the head. A shaft portion (shaft portions 101, 151) formed in length, and the shaft from the front side of the game board with respect to holes (nail holes 52, 202, 302) formed in advance in the game board Part is inserted and held on the game board,
In the shaft portion, a holding portion (holding portion 111) formed with a predetermined outer diameter that can be held in the hole portion of the game board,
A contact portion (contact portion 113) that is positioned on the front side of the front surface of the game board and that contacts the game ball;
A part of the shaft portion between the holding portion and the contact portion (neck portion 152), or the holding portion is a hard portion whose surface is harder than the contact portion along the axial direction of the shaft portion. And
In the gaming nail, a part of the hard portion slightly protrudes on the front side with respect to the front surface of the game board, and the hard board is located on both front and rear sides with respect to the front surface of the game board. A gaming machine characterized by being held in

  According to the gaming machine described in the feature A1, the adjustment operation of the game nail on the resin game board can be suitably performed. That is, since the hard part of the game nail is located on both the front and rear sides with respect to the front surface of the game board, even if the game nail may contact the edge part of the hole part on the front surface of the game board, the part is the contact part. It is a harder part. Therefore, breakage of the game nail due to contact between the edge portion of the hole and the game nail can be suppressed, and adjustment of the game nail on the resin game board can be suitably performed.

  In addition, since the hard part protrudes slightly from the front surface of the game board, it is easy to check whether the game nail is in the specified position by visually checking the boundary position between the hard part and the softer part than the hard part. The game nail can be easily managed at the specified position. In the case of a transparent game board, even if a part of the hard part protrudes forward from the front surface of the game board, the amount of protrusion is small, and the entire hard part is less than the front face of the game board. Since the hard part can be seen through even on the back side, there is no big difference in appearance with the hard part completely entering the back side from the front of the game board. Therefore, it is possible to make the game nail easy to manage at a specified position while making the appearance as a game machine equivalent to a conventional game machine using a resin game board, and it is more suitable for the adjustment work of the game nail. Can be done.

  Note that the hard part in the feature A1 slightly protrudes may be a small amount of approximately one fifth or less of the length of the hard part along the axial direction of the shaft part. With such a configuration, it is possible to provide a gaming machine that allows easy adjustment of the game ball while maintaining high durability such as fatigue strength of the game nail resulting from the formation of the hard portion.

<Feature A2>
The gaming machine according to claim A1, wherein the gaming nail is held by the gaming board in a state where the hard portion protrudes from the front surface of the gaming board to the front side with a length of 0.5 mm or less. .

<Feature A3>
A fastening allowance corresponding to a difference between an inner diameter formed as a hole portion of the game board and an outer diameter of the holding portion is set in a range from approximately 0.18 mm to approximately 0.22 mm. A gaming machine according to feature A1 or A2.

  According to the gaming machine described in the feature A3, the holding force that opposes the pulling out of the game nail in the resin game board can be kept low. Due to this decrease in holding power, the feel of adjusting the angle of the game nail is soft and workability is good, and the behavior of the game ball in contact with the game nail is close to the behavior of the game ball on the wooden game board, so that the skilled player It is possible to provide a game machine that is easy to get along with.

  In addition, it is more preferable that the tightening allowance in the gaming machine described in the feature A3 is set in a range of approximately 0.19 mm to approximately 0.21 mm. Further, the holding portion in the gaming machine described in the feature A2 has an outer diameter that is approximately 1.1 times to approximately 1.3 times the outer diameter of the contact portion, and an axial length of approximately 1.5 times. It is preferable that the ratio is set to approximately three times.

<Feature B group>
Conventionally, there is a pachinko machine as a representative example of a gaming machine. The pachinko machine has, for example, a game board that forms a game area in which game balls flow down. In the game area, a game ball is paid out when the game ball wins, and the game ball is guided to the prize opening. A number of game nails are provided that form a passage and a passage that leads to the out-out opening without winning the winning opening. A large number of game nails are driven and fixed to a game board that forms the outer shape of the game board. As this game board, wood such as veneer has been used in the past, and in recent years, resin board materials or molded products are used. Has also been used. In particular, by using a game board made of transparent resin, it is possible to make a decorative member such as a light emitter provided on the back side of the game board visible to the player, and to expand the installation area of the decorative parts more than before. (For example, refer to JP2008-161638).

  However, the holding state of the game nail differs depending on the material of the game board, and the behavior of the game ball tends to be different. For this reason, for players who are accustomed to the behavior of pachinko machine game balls using wooden game boards, there is a possibility that the game balls of pachinko machines using resin game boards may feel uncomfortable. There is a point.
