FIG.

Hereinafter, an embodiment of the present invention will be described with reference to a pachinko gaming machine which is a kind of gaming machine (hereinafter referred to as "pachinko 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 front-rear pair in a central portion thereof, and a game ball passes through the window portion 12 from the front side.

A firing handle 15 is provided on the right side of the ball plates 13 and 14, and when the player operates the firing handle 15, the game balls stored in the upper ball plate 13 are placed one by one on the front side of the game board 20. It is fired toward.

As shown in FIG. 2, the game board 20 has a game area 21 formed in an inner portion of which the outer circumference is partitioned in a substantially circular shape. A center decoration member 22 and a plurality of side decoration members 23 are provided on the left and right sides of the center and lower portions of the game area 21, and a large number of game nails are provided in the entire area of the game area 21 avoiding the decoration members 22 and 23. 100 is provided. In the area where a large number of game nails 100 are provided, there are special benefits for the player such as the general winning opening 24, the starting winning openings 25 and 26, the variable winning device 27 that opens and closes the winning opening that is opened at the time of a big hit, and the through gate 28. Provided entrance holes are provided, and game balls enter the entrance holes, whereby prize balls are paid out, or a lottery such as a jackpot 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 thereof, and a large number of game nails 100 are driven in from the front side of the game board 50 and attached.

The game board 50 is a plate-like member made 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 have to be formed by injection molding, and a plate-shaped 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, or not necessarily 1. It is not necessary to form the plate-shaped member in one sheet, and a plurality of plate-shaped members may be formed in an overlapping manner. Regarding the color of the game board 50, it may be colorless and transparent, or colored and transparent, or may be formed of a colored and opaque synthetic resin having no translucency.

FIG. 3 is a vertical sectional view showing a fixed state of 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 the front surface 51 of the game board 50 projects toward the front side. The side where the game nail 100 projects corresponds to the game area provided on the front side of the game board 20, and the game ball flows down on this front side.

As shown in FIG. 3, the game nail 100 includes an elongated shaft portion 101 and a tip end portion (projection end portion) that is one end side of the shaft portion 101 and protrudes toward the front surface 51 side of the game plate 50. It has a head 102 formed thicker than the shaft 101. The game nail 100 is made of metal, for example, made of brass, and is formed by subjecting a wire rod to a forging process such as rolling.

The shaft portion 101 has a holding portion 111 held by the game board 50 at the end opposite to the head 102. The holding portion 111 is formed in a screw shape in which two spiral protrusions are formed by knurling. The tip surface 112 on the tip 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 plate 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, is attached so as to be inclined 5 degrees above the horizontal, and the game ball that is in contact with the game nail 100 from above is the game board. It is configured to be guided to the 50 side and to easily drop the game ball along the front surface 51 of the game board 50.

An outer diameter D1 of a portion of the shaft portion 101, which is a part of the contact portion 113 and has a constant cross-sectional shape, is formed to be smaller than the outer diameter D2 of the holding portion 111, for example, about 1.85 mm. It is the outer shape of. A portion corresponding to the contact portion 113 has substantially the same outer diameter as that of the wire material, and the holding portion 111 is subjected to plastic deformation larger than that of the contact portion 113 by forging. Therefore, the holding portion 111 is harder than the contact portion 113 due to work hardening. Here, the outer diameter D2 of the holding portion 111 is the outer diameter of the largest portion corresponding to the outer peripheral side end of the protrusion that is farthest from the center axis of the shaft portion 101.

As shown in FIG. 3, with respect to the game board 50, the holding portion 111 is inserted into the thickness of the game board 50 corresponding to the inner side of the front surface 51 of the game board 50, and a part of the game board 50 is inserted. The length is set so as to project forward from the front surface 51. The amount by which the holding portion 111 projects from the front surface 51 of the game board 50 to the front side is a slight amount, and is about 0.3 mm. When the hammer hitting force for abutting the game ball and adjusting the angle is applied to the protruding portion of the game nail 100, a high bending stress is generated in the edge portion of the nail hole 52 provided in the game board 50, and the nail is nailed. The contact force between the edge of the hole 52 and the surface of the game nail 100 is also high. In this case, the holding portion 111 having a harder surface than the abutting portion 113 and the like comes into contact with the edge portion of the nail hole 52, so that the game nail 100 can be prevented from being broken. The length of the holding portion 111 along the axial direction is, for example, about 4.0 mm, and the projection amount by which the game nail 100 projects from the front surface 51 of the game board 50 is, for example, about 18.5 mm. There is.

Before inserting the game nail 100 into the game plate 50, a nail hole 52 having a smaller diameter and a circular cross section than the holding portion 111 is previously drilled, 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 being pressed by the head 102 and rotating along the screw shape of the holding portion 111 in the nail hole 52.

The inner diameter D3 that is pre-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 plate 50 within a range of approximately 250N to approximately 500N. Is set. The pulling-out force is obtained by measuring the force in the direction of pulling out the game nail 100 along the axial direction while holding the head 102 with a tool, and measuring the force with which the game nail 100 is pulled out. To be This pull-out force changes depending on the tightening margin corresponding to the difference between the inner diameter D3 of the portion that holds 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 as the tightening margin increases, the pull-out force increases. Becomes higher and the tightening margin becomes smaller, the pulling force becomes lower.

As for the pulling-out force, a plurality of types of nail holes 52 having different inner diameters D3 are punched in the game board 50, and the gaming nails 100 with the outer diameter D2 of the holding portion 111 being fixed are inserted and fixed. Was set by measuring. From the 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 of which the holding portion 111 is 2.08 mm, when the inner diameter D3 of the nail hole 52 is in the range of 1.84 mm to 1.88 mm (gradual change range), the nail hole Every time the inner diameter D3 of 52 changed by 0.01 mm, it changed within the range of 30N to 50N. Further, in this gradual change range, the amount of decrease in the pull-out force gradually decreased each 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 set to 1.89 mm as a range (a sudden change range) in which the inner diameter D3 is expanded from 1.88 mm, the pulling-out force is greatly reduced as compared with the case of 1.88 mm. The pull-out force decreased by 60 N or more with respect to the change of the inner diameter D3 of the nail hole 52 of 0.01 mm. In the present embodiment, 1.88 mm at which the pulling-out force greatly decreases with respect to the amount of change in 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 pull-out force was about 440 N when the inner diameter D3 of the nail hole 52 was 1.88 mm.

The difference in the inner diameter D3 of the nail hole 52 affects the feel when hitting the head 102 of the game nail 100 with a hammer to adjust the angle of the game nail 100 to a specified angle. The game board 50 made of synthetic resin 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 game board 50 made of synthetic resin, and is made of wood. Soft on the board. This difference also affects the behavior of the game ball that abuts on the game nail 100. In a wooden game board, the game ball that abuts on the game nail easily repels, and in comparison, in the game board 50 made of synthetic resin. Is hard to repel.

Also, the durability of the game nail 100 against repeated bending 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 to 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. In the case of causing bending deformation accompanied by, the larger the inner diameter D3 of the nail hole 52, that is, the lower the pulling-out force, the more the number of bendings until the game nail 100 is broken, and the higher the durability. Even when the durability test is performed by repeatedly applying a force to a portion corresponding to the contact portion 113 of the game ball and without plastic deformation, the larger the inner diameter D3 of the nail hole 52, that is, the lower the pulling force, the durability. Became high.

The pulling force of the game nail 100 is about 250 N in the wooden game board, and in order to make the behavior of the game ball in this wooden game board and the feel at the time of adjusting the game nail 100 closer, the game nail in this embodiment. The pulling force of 100 is set to be within a range of approximately 250N to approximately 500N. As the setting of this pulling-out force, for example, it is better to set it to about 250N to about 400N, and it is preferable to set it to about 250N to about 350N. However, as the allowable range of the pulling 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. Preferably.

FIG. 4 is a diagram schematically showing the two game nails 100 provided in the upper portion of the upper starting winning opening 25. The two game nails 100 are bent in the direction in which the heads 102 of the two game nails 100 are separated from each other. The angle of the two game nails 100 is set by inserting the metal gauge 30 having a thin plate shape and having the interval W set to the specified interval W so that the interval between the base portions of the head 102 is set. By setting the width of the head 102 of the game nail 100 to be wider than the base side of the game nail 100 as the prescribed interval W, the player can easily see the game ball entering the starting winning opening 25. .. However, depending on the pulling-out force of these two game nails 100 and the surrounding game nails 100, even if the game nails 100 are arranged at exactly the same arrangement, at the same interval, and at the same angle, a game ball to the starting winning hole 25. The winning probabilities of are different. For a player who has become accustomed to conventional pachinko machines, if the winning probability is lower than it looks, he/she may have an aversion to the amusement hall or the gaming machine manufacturer. The force is preferably set to a low value close to that of a wooden game board. As a result, the behavior of the game ball that abuts on the game nail 100 is close to the behavior of the game ball on the wooden game board, and it is possible to provide a game machine that is familiar to a skilled player.

As described above, in the pachinko machine 10, the holding portions 111, which are hard portions having a harder surface than the contact portions 113 of the game nail 100, are located on both front and rear sides with respect to the front surface 51 of the game board 50. Therefore, 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 contact between the edge portion of the nail hole 52 and the game nail 100 can be suppressed, and the adjustment work of the game nail 100 on the resin game board 50 can be suitably performed.

Further, the holding portion 111, the surface of which 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 is possible to easily confirm whether or not the game nail is at the specified position, and place the game nail 100 at the specified position. It can be easy to manage. Further, since the game board 50 is transparent, the holding portion 111 can be seen through by the transparent game board 50, and further, since the holding portion 111 that projects forward from the front surface 51 of the game board 50 has a small protrusion amount, There is no great difference in appearance from the one in which the holding portion 111 is completely inward from the front surface 51 of the game board 50. In the conventional pachinko machine using a game board made of resin, the holding part is located on the back side of the front surface of the game board, but the appearance is not different from that of the pachinko machine and it is easy to manage the game nail 100 at the specified position. It can be a machine.

Further, the drawing force of the game nail in the conventional resin game board is set to a value larger than 500 N, which is more than twice the drawing force in the wooden game board. Compared with the wooden game board, the withdrawal force of the resin game board changes significantly with respect to the change of the tightening margin. Since the amount of change with respect to the change of the inner diameter is small, the tightening margin is increased to a size where the amount of change is small, and the pulling force of the game nail is large accordingly.

On the other hand, in the pachinko machine 10 according to the present invention, the pulling force of the game nail 100 on the resin game plate 50 is set to be a low tightening margin, and the holding force of the game nail 100 is suppressed to be low. Due to this reduction in holding force, the feel of the angle adjustment of the game nail 100 is soft and the workability is good, and the behavior of the game ball that abuts on the game nail 100 is close to the behavior of the game ball on the wooden game board, so that the skill of the skilled player is improved. It is possible to make the game machine familiar to the player.

Here, in place of the first embodiment described above, the result of the game such as winning the prize hole, etc., without strict dimensional management so that the pulling force for all the game nails 100 is set low. Only the pulling-out force for the game nail 100 (specific game nail 100a) that is apt to affect may be reduced. As shown in FIG. 3, a plurality of specific game nails 100a provided on the upstream side of the winning opening, near the entrance of the winning passage, or in a specific portion 61 such as a portion where the game ball in the game area 21 first comes into contact. For the nail hole 52 provided with, the center value of the allowable dimension of the inner diameter D3 may be set to be 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 having different tightening margins, and the nail hole 52 of the specific game nail 100a is 0.01 mm in size relative to the standard dimension of 1.88 mm. On the other hand, the range is set as an allowable dimension, while the general game nails 100b other than the specific game nail 100a have an allowable dimension from 0.01 mm to 0.03 mm from the reference dimension. Although the average dimension has a difference of 0.01 mm, the machining speed can be increased and the management cost can be reduced for the nail hole 52 whose allowable dimension has been expanded. The specific game nail 100a that is easily applied can have improved functionality such as durability and a soft feel when hit with a hammer.

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

As shown in FIG. 5, the nail hole 202 in the second embodiment is formed in a stepped circular hole shape having a large inner diameter D4 on the front surface 201 side of the game plate 50 from which the game nail 100 projects, and at the back side. The inner diameter D3 is formed smaller than the inner diameter D4 on the front surface 201 side. The holding portion 111 of the game nail 100 is held at a portion having an inner diameter D3 on the back side. The amount of protrusion of the game nail 100 from the front surface 201 of the game plate 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 in front of the front surface 201 of the game plate 200. .. The stepped nail hole 202 is provided at a position where the specific game nail 100a described above is arranged, and the general game nail 100b is provided with the nail hole 52 having a constant cross section in the above-described first embodiment ( 2 and 3).

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

The inner diameter D3 of the nail hole 52 of the general game nail 100b has the same reference dimension as the inner diameter of the stepped nail hole 202, and is smaller than the reference dimension in the first embodiment, for example, 0.02 mm smaller inner diameter. Although the pull-out force of the game nail 100 is increased by the amount by which the reference dimension is reduced, the holding length of the holding portion 111 held by the inner diameter D3 in the axial direction is formed short in the stepped nail hole 202, and 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. With this configuration, the inner diameter D3 of the portion holding the holding portion 111 of the general game nail 100b and the specific game nail 100a can be made common, and can be processed by the same tool. Then, when processing the inner diameter D3 on the back side of the specific game nail 100a is slower than when processing the inner diameter D3 of the general game nail 100b, the axis of the tool is less prone to wobbling and the accuracy is improved. 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 of 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 is provided. The game ball becomes easy to bounce, and the behavior of the game ball close to a wooden game plate can be easily realized with the game plate 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 that of the first and second embodiments, and the game board 50 is formed thick. FIG. 6 is a vertical cross-sectional view showing a fixed state of the game nail according to the third embodiment. Hereinafter, with respect to the game nail fixing structure according to the third embodiment, parts different from the first embodiment will be described.

In the game nail 150 according to the third embodiment, the shaft portion between the head 102 and the holding portion 111 does not have a constant cross-sectional shape, and a constricted portion 152 having a narrow outer periphery is provided in a portion near the holding portion 111. The length of the constricted portion 152 is longer than that of the game nail 100 in the first embodiment. The constricted portion 152 is formed by thinly forging a brass wire material, and its surface is formed harder than the contact portion 113 or the like with which the game ball abuts due to work hardening. The constricted portion 152 has the thinnest central portion in the longitudinal direction of the shaft portion 151, is formed to be gradually thicker on both sides, and is formed in a circular arc shape in a side view. The axial length of the constricted portion 152 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 project 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 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 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 above-described first embodiment.

Since the game nail 150 according to the third embodiment is provided on the game plate 300, the gap between the contact portion 113 and the holding portion 111 with which the game ball abuts is separated from the game nail 100 according to the first embodiment.

It is provided on the outer peripheral surface away from the center and is set so as to be easily visible to the operator. Further, in the direction in which the facing inclined surfaces of the receiving member 513 and the spacer 522 are parallel to each other, the same direction side (perpendicular to the paper surface of FIG. 9) with respect to the rotation center axis when adjusting the directions of the receiving member 513 and the spacer 522. The fixing screw 523 of the receiving member 513 and the vertical groove portion 522a of the spacer 522 are disposed on the rear side in the direction. Therefore, for example, when the operator wants to make the state shown in FIG. 9, the worker sets the vertical groove portion in the same direction side (the back side in the direction perpendicular to the paper surface of FIG. 9) with respect to the rotation center axis of the receiving member 513 and the spacer 522. 522a and the fixing screw 523 may be arranged. By this adjustment operation, a portion of the receiving member 513 that is formed high on one side (right side in FIG. 9) of the rotation center axis of the receiving member 513 and the spacer 522 so as to approach the spacer 522 and the receiving member of the spacer 522. A portion far from the spacer 513 is located, and a portion far away from the spacer 522 of the receiving member 513 and a portion of the spacer 522 located on the receiving member 513 side 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 in parallel with the front surface and the rear surface of the game board by using the vertical groove portion 522a and the fixing screw 523 as a mark, and the game nail replacement work can be efficiently performed. It can be carried out. In particular, if the game board is transparent and the front side can be visually recognized from the front side, the position of the fixing screw 523 can be confirmed even when the game board is sandwiched between the spacer 522 and the receiving member 513. While the position of the vertical groove portion 522a can be adjusted, the orientation of the spacer 522 and the receiving member 513 can be adjusted more easily.

As shown in FIG. 9, the receiving member attachment shaft 514 to which the receiving member 513 is attached to one end side is longer than the through hole of the receiving side projecting portion 543 so that the opposite end thereof penetrates the receiving side projecting portion 543. The receiving portion fixing member 515 is provided at the opposite end. The receiving portion fixing member 515 is formed in an annular shape having a through hole in which a female screw is formed in the central portion, and the outer peripheral surface is formed by undulating in a striped shape 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 at the time of rotating the 515. The operator loosens the receiving portion fixing member 515 in advance to the extent that the receiving portion fixing member 515 is separated from the base member 511, and then sets the orientation of the inclined surface of the receiving member 513 integrated with the receiving member mounting shaft 514 by the fixing screw. The rotary operation is performed in an appropriate direction determined by the positions of 50 and the base member 511. When the receiving portion fixing member 515 on the opposite side of the receiving member mounting shaft 514 is screwed into and brought into contact with the outer side surface of the receiving side protruding portion 543 in a state of being pressed after having been set in an appropriate direction, this contact force is obtained. By this, 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 one side opened along the axial direction is provided in the central portion of the receiving member attachment shaft 514, and the receiving side projecting portion 543 is provided such that the side where the hole portion 613 is provided is the receiving member 513 side. It is installed. The hole portion 613 communicates with the through hole of the receiving member 513, is fixed to the receiving-side protruding portion 543 in a state in which the side on which the pushing operation member 562 is provided is open and extends in the advancing direction side of the pushing operation member 562. .. The broken game nail pushed out from the game plate 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 so that the length from the entrance to the bottom is longer than the entire length of the game nail to be replaced. Further, the hole 613 of the receiving member mounting shaft 514 abuts on 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 is performed. When the direction and the axial direction of the nail hole into which the game nail is inserted are made to substantially coincide with each other, it is preferable that the bottom surface is formed in a shape that is 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 to the game board by inclining upward by 5 degrees, the continuous direction of the inner diameter of the hole portion 613 is the moving direction of the pushing operation member 562. It may be parallel, that is, may have a circular cross-section with a constant inner diameter, and may have a shape in which the inner diameter on the inner side gradually decreases at an inclination angle corresponding to an angle at which the game nail is inclined with respect to the game plate, for example, less than 5 degrees. It is preferable that the bottom surface of the hole portion 613 be inclined downward toward the inner side when the game nail is pushed out. Further, the cross section of the hole 613 of the receiving member mounting shaft 514 may have a shape other than a circular shape, but by making the cross section a circular shape, the game nail exchanging tool 500 is arranged in any of the up, down, 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 constant angle. Further, as the hole 613 of the receiving member mounting shaft 514, the inner diameter may be gradually increased toward the inner side corresponding to the advancing direction side of the pushing operation member 562, and in this case, the broken gaming nail. Is more easily guided to the back side, which is preferable. The bottom side of the hole 613 may be open, but it is not penetrated, or if a lid member that can close the bottom side in the case of a penetrating shape is provided, it is a broken game nail. Is preferable because it can be prevented from falling to the rear surface side of the game board and preventing a problem such as obstructing the flow of the game ball.

Next, a method of operating the game nail changer 500 will be described. 12 and 13 are explanatory views showing the procedure for exchanging members of the game nail exchanging tool 500. In the operation of using the game nail exchanging tool 500, first, the operating member 512 and the tip side support member 516 attached to the game nail exchanging tool 500 are confirmed, and if necessary, these members are exchanged with other members. Then, the game nail exchanging tool 500 suitable for work is obtained.

As a procedure for exchanging the actuating member 512 and the tip side support member 516, a procedure for exchanging a combination of the pushing support member 561 and the pushing actuating member 562 with a combination of the inserting support member 571 and the inserting actuating member 572. An example will be described. At the time of replacement, first, the fixing operation member 519 is rotated with respect to the rotation operation member 518 in a loosening direction, and the rotation operation member 518 is removed from the fixing operation member 519 (see FIG. 12A). Next, the push-out operation member 562 is pulled out from the rotation operation member 518 by making the opening hole portion of the rotation operation member 518 face downward (see FIG. 12B).

After the push-out operation member 562 is pulled out, the knob portion 586 of the push-out support member 561 is operated to pull out the push-out support member 561 from the operation recessed portion 532 (see FIG. 12C). After that, the insertion support member 571 and the insertion operation member 572 are sequentially attached to the base member 511, and finally, the fixing operation member 519 is tightened from the end side of the rotation operation member 518 to complete the member exchange (Fig. 13). In addition, by reversing the above-described procedure, these members 571 and 572 are inserted into the pushing support member 561 and the pushing support member 571 and the pushing operation member 572 with respect to the game nail exchanging tool 500. It can be replaced with the pushing operation member 562.

Next, a procedure for replacing the game nail 100 using the game nail exchanging tool 500 when the game nail 100 provided on the game board 50 is broken will be described with reference to FIGS. 14 to 17. 14 and 15 are explanatory diagrams of the pushing operation of the broken gaming nail by the gaming nail exchanging tool 500, and FIGS. 16 and 17 are explanatory diagrams of the inserting operation of the gaming nail by the gaming nail exchanging tool 500. 14 to 17, the shape and arrangement 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, the pushing support member 561 and the pushing operation member 562 are attached as the game nail exchanging device 500 in order to push out the broken game nail 100. Next, the orientation of the receiving member 513 is adjusted to correspond to the position of the broken game nail 100. In this description, as shown in FIG. 14A, a case where the game nail exchanging tool 500 is arranged so that the base member 511 is located above the broken game nail 100 and the game nail 100 is pushed out is described. It is illustrated. In this case, in the inclined surface of the receiving member 513, the tip side of the receiving side protrusion 543 (the lower side of FIG. 14A) is separated from the operating side protrusion 542, and the base end side of the receiving side protrusion 543 (see FIG. 14(a) (upper side of 14(a)) is rotated to align the receiving member 513 in a direction closer to the operating side protrusion 542, and after the alignment, the receiving portion fixing member 515 is screwed into the base member 511. The receiving member 513 is fixed.

After fixing the receiving member 513, the push-out support member 561 is positioned so that the tip-end side portion of the push-out support member 561 slightly enters the through hole of the tip-side protrusion 544 of the game nail exchanging tool 500. The knob portion 586 is operated to secure a wide gap between the pushing support member 561 and the receiving member 513. In this case, the extruding tip 581 of the extruding operation member 562 may project from the extruding support member 561 toward the receiving member 513, but the extruding tip 581 rotates in the direction away from the receiving member 513. It is necessary to rotate the operation member 518 so that the extrusion tip 581 does not project from the extrusion support member 561 to the receiving member 513 side. Therefore, the extrusion tip 581 may be broken or other portions of the extrusion tip 581 may be damaged. It is preferable because scratches can be prevented.

With the above, the preparation of the gaming nail exchanging tool 500 in a single state is completed, and next, the main body 541 of the gaming nail exchanging tool 500 is gripped, and the gap between the game board recesses 533, specifically, the receiving member 513. The game nail exchanging tool 500 is moved so that the game board 50 is located between and the tip portion 585 of the pushing support member 561. In this movement, the game nail exchanging tool 500 is arranged such that the center of the receiving member 513 is located on the rear side of the broken game nail 100. After the game nail exchanging tool 500 is arranged, the spacer 522 is arranged between the tip portion 585 of the pushing support member 561 and the game board 50, and the knob portion 586 of the pushing support member 561 is rotated to receive the receiving member. The pushing support member 561 is advanced to the 513 side, and the gaming board 50 and the spacer 522 are sandwiched between the tip end portion 585 of the pushing support member 561 and the receiving member 513 (FIG. 14B and FIG. 15A).

Here, whether or not to dispose the spacer 522 between the tip portion 585 of the pushing support member 561 and the game plate 50 can be selected according to the state of the broken game nail 100. When the broken game nail 100 is projected from the front surface 51 of the game plate 50, the through hole of the spacer 522 is fitted into the protruding portion, and the tip of the pushing operation member 562 is inserted into the spacer 522. After operating the operating member 518 to advance the operating member 562 for extrusion so that the operating member 562 for extrusion enters the spacer 522, the knob 586 of the supporting member 561 for pushing is rotated to support the member for extrusion. It is preferable that the spacer 522 and the game board 50 are sandwiched between 561 and the receiving member 513. On the other hand, when the tip portion of the broken game nail 100 is located deeper than the front surface 51 of the game plate 50 and is recessed toward the nail hole 52 side, the spacer 522 is not used and the nail hole 52 is not used. Alternatively, the tip of the pushing operation member 562 may be aligned.

After that, when the turning operation member 518 is turned to move the pushing operation member 562, the tip of the pushing operation member 562 comes into contact with the broken game nail 100. Further, if the rotation operating member 518 continues to rotate, as shown in FIG. 14C, the rotation operating member 518 contacts the base member 511, 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 projects to the rear surface side of the game board 50, and the broken game nail 100 is pushed out from the game board 50, It is inserted into the hole 613 of the receiving member mounting shaft 514.

As shown in FIG. 15B, the hole portion 613 of the receiving member mounting shaft 514 communicates with the through hole of the receiving member 513, and the bottom surface in the state where the inclined surface of the receiving member 513 is in close contact with the rear surface of the game board 50. The inner surface is inclined so that the side is located below. Therefore, the broken game nail 100 is easily pushed into the back side of the hole 613 after being pushed out from the game board 50, and the broken game nail 100 can be prevented from falling to the rear surface side of the game board 50. it can.

After the broken game nail 100 is pushed out from the game plate 50, the turning operation member 518 is rotated in the reverse direction, and the pushing operation member 562 is retracted in the direction away from the receiving member 513. After the tip of the pushing operation member 562 has come out from the front surface 51 of the game board 50, the knob portion 586 of the pushing support member 561 is operated to retract the pushing support member 561, and the gaming board 50 and the pushing support member. When the spacer 522 is arranged between the spacer 522 and 561, the spacer 522 is removed. By the above operation, the game nail exchanging tool 500 can be moved with respect to the game board 50, and the game nail exchanging tool 500 can be removed 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 received on the front surface 51 side of the game board 50. The game nail exchange tool 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 bent and deformed extremely, it may be preferable to remove the game nail 100 from the rear surface side of the game board 50 to the front surface 51 side because the nail hole 52 of the game board 50 is less likely to be shaved. is there. According to the situation of the game nail 100, the operator can select the pushing direction of the game nail 100 in which the nail hole 52 is difficult to be cut, and the game nail exchanging tool 500 is used to break the game nail 100 from any side. Can be removed from the game board 50.

Next, the insertion operation of the game nail 100 will be described. After removing the broken game nail 100 from the game board 50, using the game nail exchanging tool 500, a inserting operation for inserting a new game nail 100 is performed. First, the push-out support member 561 and the push-out operation member 562 are removed and replaced with the insertion support member 571 and the insertion operation member 572. Then, similarly to the pushing operation of the game nail 100 described above, the orientation and fixing of the receiving member 513 are performed. However, if the direction of the receiving member 513 is fixed by the push-out operation, the inserting operation can also be normally performed in that direction, so this adjustment and fixing operation need not necessarily be performed. After that, the grip portion 596 of the insertion support member 571 is positioned so that the distal end side portion of the insertion support member 571 slightly enters the through hole of the distal end side protrusion 544 of the gaming nail changer 500. Is operated 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 exchanging tool 500 is moved so that the game board 50 is located between the receiving member 513 and the tip end portion 595 of the insertion support member 571, and the game is played. The game nail exchanging tool 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 arranging the game nail exchanging tool 500, the knob portion 596 is operated so as to proceed to the receiving member 513 side of the inserting support member 571. After advancing the insertion support member 571 to the receiving member 513 side, a new game nail 100 is penetrated 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 arrange in the through-hole, so the through-groove 599 is directed sideways or upward. After adjusting the orientation of the insertion support member 571 so as to be opened, the game nail 100 is arranged in the through hole (see FIGS. 16B and 17A). It should be noted that a new game nail 100 may be inserted into the through hole of the insertion support member 571 before aligning the game nail exchanging tool 500 with the game plate 50, but in this case, the tip side protrusion When the insertion support member 571 is rotated with respect to the portion 544, the tip side of the game nail 100 is pinched and supported to prevent the game nail 100 from falling.

After that, when the turning operation member 518 is turned to advance the insertion actuating member 572, the tip end thereof comes into contact with the head 102 of the game nail 100. Further, if the rotation operating member 518 continues to rotate, as shown in FIG. 16C, the rotation operating 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 a depth substantially the same as the other game nails 100.

After the game nail 100 is inserted into the game plate 50, the rotation operation member 518 is rotated in the reverse direction to retract the insertion operation member 572 in the direction away from the receiving member 513. After that, the game nail exchanging tool 500 is moved so that the newly inserted game nail 100 comes 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 tip end side hole 597 side of the base end side support hole 598 of the insertion support member 571, After operating the knob 596 of the insertion support member 571 to move the insertion support member 571 toward the game plate 50, the game nail 100 is pulled out to the outside of the insertion support member 571. On the other hand, when the head 102 of the game nail 100 is separated from the end surface on the tip end side hole 597 side of the base end side support hole 598 of the insertion support member 571, it is inserted in the direction away from the game plate 50. After moving the insertion support member 571, the game nail 100 is pulled out to the outside of the insertion support member 571.

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

Next, a method of 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 exchange tool 500 is arranged on the game board 20 from which the center decoration member 22 is removed.

The center decoration member 22 provided in the central portion of the game board 20 is preferably attached and fixed from the front side of the game board 20, and when the attached and fixed center decoration member is removed, it is formed in the central portion of the game board 50. The exposed opening 50a is visibly exposed from the front side. By arranging the game board 50 so as to enter into the game board recess 533 of the game nail exchanging tool 500 through the opening 50a, a large number of top, bottom, left and right sides of the opening are arranged as illustrated in FIG. The center portion of the rotation operation member 518 of the game nail exchanging tool 500 can be positioned with respect to the game nail 100 to perform the exchanging work of 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, and when the base member 511 is located above the gaming nail 100 to be replaced, the receiving member 513 has the orientation illustrated 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 replaced, or is located on the lower side, 90 degrees or 180 degrees with respect to the above-described angle. The receiving member 513 is fixed to the moved position, the actuating member 512 and the nail hole 52 are located on the same axis, 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.

The game nail exchanging tool 500 does not necessarily have to be arranged in the direction in which the base member 511 is located 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 located on the diagonal side with respect to the game nail 100. In this case as well, the actuating member 512 and the nail hole 52 are located coaxially in that direction, and the receiving member 513. The orientation of the receiving member 513 may be adjusted so that the inclined surface of the contact plate contacts the rear surface of the game board 50 in parallel. Further, in the case where the game nails 100 are arranged at a narrow interval, those having a thin shaft as the outer shape than the above-mentioned tip side support member 516 and the spacer 522 are prepared, and the depth of the game board recessed portion 533 is also set. , A larger base member corresponding to the position of the game nail that needs to be replaced may be prepared, or the game board 20 is removed from the pachinko machine 10 and the game nail changer 500 is mounted from the outer peripheral side of the game board 20. The game board 50 may be arranged in the game board recessed portion 533 to perform the game nail replacement work.

As described above, according to the game nail exchanging tool 500, the game nail 100 broken by the pushing operation member 562 is removed from the game plate 50, and the new game nail 100 is inserted by the inserting operation member 572. It can be inserted and fixed in. That is, the game nail exchanging tool 500 can be used as a tool suitable for exchanging game nails.

In addition, the inclined surface of the receiving member 513 as the receiving portion that abuts the game plate 50 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 rotatably provided around the central axis. Therefore, due to the inclined surface of the receiving member 513 facing the operating side protruding portion 542 side where the game board 50 is arranged, the lower portion 513b located closer to the receiving side protruding portion 543 and the receiving side protruding portion than the lower portion 513b. A high portion 513a located on the side separated from 543 is formed. Then, when the rear surface of the game plate 50 is brought into contact with both the low portion 513b and the high portion 513a of the receiving member 513, the rear surface of the game plate 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 operation member 512 and the insertion operation member 572 come into contact with the game nail 100 and a large pressing force acts to move the game nail 100, the rear surface of the game board 50 is affected. The actuating member 512 easily advances along the axial direction of the game nail 100 that is inclined with respect to it. Further, by rotating the receiving member 513 to change the direction of the inclined surface, the game nail exchanging tool 500 (base member 511) is brought closer to the game nail 100 from the side where the operator can easily work, and the game nail 100 is moved. Can be replaced. Therefore, even an operator unfamiliar with the game nail 100 replacement operation can relatively easily replace the game nail 100.

One end face of the spacer 522 facing the receiving member 513 side is provided to be inclined with respect to the through hole of the spacer 522 because the game nail 100 is provided to be inclined with respect to the front face 51 of the game plate 50. The angle corresponds to the inclination angle of the inclined surface of the receiving member 513 with respect to the central axis of the actuating member 512. Then, a proximity portion (a right side portion on the lower end surface of the spacer 522 in FIG. 9) located on the side closer to the tip-side protruding portion 544 and a separation portion (a portion located on the side separated from the tip-side protruding portion 544 from the proximity portion ( The left side portion of the lower end surface of the spacer 522 in FIG. 9) is formed on one end surface of the spacer 522. When the rear surface of the game board 50 is brought into contact with both the low portion and the high portion of the receiving member 513, the proximity portion and the separated portion of the spacers 522 can both come into contact with the front surface 51 of the game plate 50. It is set to the relative position. 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 plate 50, the moving direction of the actuating member 512 is tilted along the axial direction of the game nail. The exchanging tool can be easily installed, and the exchanging work of the game nail can be efficiently performed.

The insertion support member 571 has a distal end side hole 597 and a base end side support hole 598 which are formed through the insertion operation member 572 in the axial direction, in the moving direction of the insertion operation member 572. A penetrating groove 599 through which a game nail formed penetratingly formed on one side perpendicularly intersecting can be taken out is provided. The insertion support member 571 is attached to the first support portion of the base member 511 so as to be rotatable about the movement direction of the insertion operation member 572. Therefore, the tip end side hole 597 and the base end side support hole 598 can support the periphery of the game nail 100 and apply the pressing force of the inserting operation member 572 to the game nail 100 in a stable state. The game nail 100 can be securely inserted and fixed to the game board 50. Further, after the fixing, the gaming nail exchanging tool 500 can be easily removed from the gaming board 50 by simply moving the insertion support member 571 to the side crossing the axial direction of the gaming nail 100 using the through groove. You can Therefore, it is possible to prevent the game board 50 from being scratched when the game nail changer 500 is removed.

The push-out operating member 562 as the operating member 512 and the inserting operating member 572 are supported by the push-out supporting member 561 or the inserting supporting member 571 as the tip-side supporting member 516 on the tip side along the moving direction thereof. The base end side of the operating member 512 is supported by the base end side support member 517 at a position separated from the support portion by the operation recessed portion 532. Therefore, by separately forming separate supporting members corresponding to the pushing operation and the inserting operation to reduce the manufacturing cost, the length of the section along the traveling direction in which the operating member 512 is supported is set to be long. The operating member 512 can be easily moved along the traveling direction, and the game nail 100 can be efficiently replaced.

The outer shapes of the knob portions 586 and 596 of the pushing support member 561 and the insertion support member 571 are formed to have a diameter larger than that of the through hole of the tip side protrusion 544 of the base member 511. Therefore, up to the position where the knobs 586, 596 abut the tip-side protrusion 544 is the movable range along the traveling direction of the operating member 512 in the pushing support member 561 and the insertion support member 571, and beyond that. The pushing support member 561 and the insertion support member 571 cannot move to the side. Therefore, an operator does not inadvertently operate the pushing support member 561 or the insertion support member 571 to cause the pushing support member 561 and the insertion support member 571 to project toward the game board 50 side, It is possible to prevent the game board 50 from being scratched.

Further, the pushing support member 561 and the insertion 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 operating member 512 is supported by the supporting member 571. Then, the pushing support member 561 and the insertion support member 571, and the member in which the base end side support member 517 and the rotation operation member 518 are integrated together, are both receiving members 513 from the side separated from the receiving member 513. It is attached to the base member 511 by performing a screwing operation in the direction approaching. Therefore, when the actuation member 512 is advanced by the turning operation of the turning operation member 518, the pushing support member 561 and the insertion support member 571 are turned by the frictional resistance with the actuation member 512, and they are supported. The members 561 and 571 may move along the axial direction of the actuating member 512. However, as described above, the pushing support member 561 and the insertion support member 571 are prevented from moving beyond a certain amount by the knobs 586 and 596, so that the game nail 100 can be smoothly replaced. ..

The present invention is not limited to the above-mentioned embodiment, and may be modified and implemented as described below, for example. 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-described embodiment will be designated by the same reference numerals, and the description thereof will be omitted.

The receiving member 513 of the game nail exchanging tool 500 in the above embodiment is formed in an annular shape, and the receiving portion that abuts on the game plate is formed of a flat inclined surface, but the receiving portion is not necessarily formed in the above shape. There is no need to use the receiving member, and the receiving member may have another shape having a receiving portion that forms a portion having a different height position with respect to the receiving-side protruding portion 543. For example, as shown in FIGS. 19A and 19B, the receiving member 701 may have a shape in which the receiving portion is intermittently formed with respect to the receiving member 513 in the above embodiment. 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 to have a shape that abuts the game plate on a part of the plane, and a plurality of protruding portions that abut the game plate in a dot shape such as a hemispherical protruding portion are provided. The same effect as that of the receiving member 513 can be obtained even if the tip surfaces of the protrusions are located on one plane and the one plane is a plane inclined with respect to the traveling direction of the operating member.

The receiving portions of the receiving members 513, 701 that come into contact with the game plate are the first receiving portion having a low height position in a state of being inclined by about 5 degrees with respect to the central axis parallel to the moving direction of the operating member 512, and the height. The case where the second receiving portion having a high position comes into contact with the game board has been described, but the center of the operating member 512 is brought into contact with the game board in a state of being inclined at another angle such as approximately 3 degrees or approximately 8 degrees. It may be set at a different angle with respect to the axis. Further, the receiving members 513, 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, and between the receiving portions. It is preferable to set the extension line of the central axis of the actuating member 512 to be located at the portion, which 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 surface side of the game board, the lower part 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. In order to be able to guide the hole 613 of the receiving member mounting shaft 514 (see FIG. 15B), the receiving member 701 has a portion in which the central portion of the through hole of the receiving member 701 is recessed when viewed in the axial direction. Is preferred. Further, as shown in FIG. 19B, a through hole for a fixing screw provided in the receiving member 513 is provided on the side of the position where the receiving portion of the receiving member has the lowest height, or the through hole is For example, the fixing screw may be provided at the highest position to facilitate the use of the fixing screw as a mark when adjusting the orientation of the receiving member 513. In this case, the vertical groove portion 522a of the spacer 522 also has 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. It is preferable to be provided at a position where

The adjustment of the orientation of the receiving member 513 does not necessarily have to be performed by the rotating 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 the closed 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.

In the game nail exchanging tool 500 in the above-described embodiment, the vertical groove portion 522a and the fixing screw 523 are used as marks to easily set the orientations of the receiving member 513 and the spacer 522 to be parallel to the front surface and the rear surface of the game board. The shape of the part to be the mark is not limited to the above-described form, and may be any shape such as a dot shape, a line shape, and a symbol, and is not limited to the case of forming the shape of a protruding or recessed member, It may be a mark drawn by painting, printing or the like. Further, the number of parts to be used as a mark does not necessarily have to be one, and may be a plurality of two or more parts which are separated from each other by a constant 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 to each other, the mark provided on the position side that is on the same direction side with respect to the rotation center axis of the receiving member 513 and the spacer 522. In order to make it easy to understand that they correspond, make sure that the symbols such as circles and squares are the same, or that the numbers on the side that is the same direction side that is different for each direction side are the same. Preferably.

Although the gaming nail exchanging tool 500 in the above-described embodiment has a plurality of parts integrated by a fixing screw or integrated by bonding or joining, the parts configuration does not necessarily have to be the above-described configuration. The base end side 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 may be formed as an integral part. Is also good. In this case, the pushing operation member 562 or the inserting operation member 572 and the turning operation member 518 are separately formed, and the pushing operation member 562 or the inserting operation is performed with respect to the turning operation through the handle portion 552. It is preferable that the member 572 is not interlocked and can be moved straight without rotating so that the force in the rotating direction is not transmitted to the game nail. On the other hand, when the rotating operation member 518 and the inserting operation member 572 are formed as an integral part, the inserting operation member 572 always rotates when the inserting operation member 572 advances, but along the rotation direction. The thread shape of the holding portion of the game nail is set 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 for advancing the inserting operation member 572. If the screw shape of the part and the holding portion of the game nail are matched with the right screw or the left screw, the game nail can be easily inserted into the game plate and the head of the game nail can be prevented from being scratched. It is preferable because it is possible to 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 plate, the inserting operation member 572 is easily rotated together with the game nail, and the head of the game nail is fixed. In order to prevent scratches, 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 to be substantially the same. The damage and scraping can be suppressed by dispersing the pressure of the contact portion. Further, in order that the insertion actuating member 572 may be easily rotated with the rotation of the game nail, the peripheral surface of the insertion actuating member 572 may be supported by a bearing such as a ball bearing to facilitate the rotation, At least the opposing surfaces of the fixed operation member 519 and the insertion operation member 572 are such 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, one side may be formed in a conical shape or the like so as to project, and in this case as well, it is possible to suppress rubbing between the insertion operation member 572 and the head of the game nail, which is preferable.

In addition, the spacer 522 does not necessarily have to be provided as a separate component separated from the pushing support member 561, and a protrusion protruding in a cylindrical shape around the through hole on the surface side of the spacer that contacts the pushing support member. The protrusion supporting member is formed with a hole having a size capable of press-fitting the protrusion, and the spacer is press-fitted and fixed to the push-out supporting member so as to be rotatable around the through hole. It may be configured. The spacer 522 may be configured to be able to be integrated with the extrusion support member 561. For example, the spacer 522 may be coated with an adhesive to contact the spacer 522 with the extrusion support member 561. You may make it joined with respect to. In this case, it is preferable that the spacer 522 is joined to the pushing support member 561 with an adhesive that forms a viscous adhesive layer so that even a small amount of the spacer 522 is integrated. When the surface and the inclined surface of the spacer 522 are deviated from each other, the spacer 522 is likely to move or rotate with respect to the pushing support member 561 so that they are close to parallel, and it is easy to perform the game nail replacement work. You can

With respect to the spacer 522 in the above-described embodiment, spacers having different lengths along the moving direction of the operating member may be prepared, and any 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 exchanging tool 500 other than the spacers are made common, spacers suitable for the game plates having different thicknesses can be used, and the thickness which cannot be dealt with only by adjusting the position of the pushing support member 561. The game nail exchanging tool 500 can be used to stably push out the broken game nail for the game board.

In the insertion support member 571 of the game nail exchanging tool 500 in the above-described embodiment, a through groove 599 used for extracting the game nail after insertion has one side intersecting with the moving direction of the insertion operation member 572. Although it is provided only on one side, it may not necessarily be provided on only one side, and may be formed on both sides intersecting the movement direction or on three sides separated by a certain angle with the movement 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 that of the distal end side hole 597 of the insertion support member 571. Further, the opening 601 of the through groove 599 does not necessarily have to be 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. ..

The rotation operation member 518 of the game nail exchanging tool 500 according to the above-described embodiment has a recessed portion on the outer peripheral surface of the handle portion 552, the fixing operation portion 553, and the like where the rotation operation is performed. It may be provided, or the surface may be subjected to a rolling process to provide a slip-like or mesh-like non-slip, or a bar-shaped portion protruding to one or both sides in the outer peripheral direction may be provided so as to be easily rotated.

With respect to the receiving portion fixing member 515 of the gaming nail exchanging tool 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, and along the central axis of the operating member 512. A positioning operation member 712 that is long may be provided so that the thin shaft portion 712a projects from the receiving member 513. When positioning the receiving member 513, the thin shaft portion 712a of the positioning operation member 712 can be inserted into the nail hole 52 to accurately position the center position of the receiving member 513 with respect to the nail hole 52. it can. The positioning operation member 712 needs to be able to be pulled out from the nail hole 52 after the positioning of the receiving member 513 and before the pushing and inserting operation of the game nail 100. For example, the penetrating penetrating on the side where the receiving member 513 is provided. By inserting the hole and the through hole from the side opposite to the side where the actuating member 512 is located, the shaft member that can be inserted into the nail hole by protruding from the abutting portion that abuts on one surface of the game board 50 by the receiving member 513. It may be a positioning operation member having.

In the above-described embodiment, the operator manually rotates the handle portion 552 with respect to the rotation operation member 518 to move the operating member 512 forward and backward, but the rotation operation member 518 is not always rotated manually. It is not necessary to perform the above operation, and a driving means such as a motor that operates electrically may be connected to the rotating operation member 518 by a drive transmission mechanism such as a gear, and the operation member 512 may be electrically advanced and retracted. That is, the rotating operation member 518 is not limited to a member operated by a direct manual operation by an operator, and may be configured to be indirectly operated by an operation on a drive unit.

The game nail exchanging tool 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 plates 50, 200, 300 described in the above embodiment. Further, the present invention is not limited to the game board and the game nail having the above-described shapes, and can be used for other forms of the game board and the game nail, and can be used as a nail for fixing a wind turbine or the like to the game board. It can also be used against. Further, it is not always necessary to use the game nail exchanging tool 500 for exchanging the game nails provided on the game board made of synthetic resin, and it may be used for the game nails provided on the wooden game board. In this case, the nail hole in the wooden game board also needs to be formed so as to penetrate from the front surface side to the rear surface side at the inner diameter of the portion where the game nail is held. Further, it is not always necessary to perform the pushing operation and the inserting operation of the broken game nail by using the one game nail exchanging tool 500, and two game nail exchanging tools 500 are prepared, and each operation is performed separately. It may be carried out by the exchange tool 500, or the game nail exchange tool 500 is used only for pushing out the game nail, and another tool is used for inserting the game nail. It may be performed by the exchange tool 500.

21. For example, as shown in FIG. 21, the gaming nail exchanging tool 500 may be a gaming nail exchanging tool 800 having a base member 801 having a different shape. FIG. 21 is a side view showing a gaming nail changer 800 according to another embodiment.

The game nail exchanging tool 800 is different from the game nail exchanging tool 500 in the above embodiment shown in FIG. 9 in the shape of the base member. In detail, in the above-described embodiment, the side portion separated from the operating member 512 is deleted from the portion where the operating-side protruding portion 542 is formed, and the outer shape portion that forms the elongated hole 534 in the main body portion 541 is deleted. It has been shaped.

As shown in FIG. 21, the base member 801 of the game nail changer 800 has a distal end side protruding portion 544 and a proximal end side protruding portion 545 on one side with respect to the actuating member 512 with the space of the operation recessed portion 532 separated. It has a continuous shape on the right side of FIG. That is, on one side of the actuating member 512, the front end side protruding portion 544 and the base end side protruding portion 545 are connected by the main body portion 802 of the base member 801, and has a shape having a U-shape in side view. A lower portion of the main body 802 of the base member 801 that corresponds to the distal end side in the moving direction of the actuating member 512 is closer to the direction away from the central axis of the actuating member 512 than the upper portion that corresponds to the proximal end side in the moving direction. The shape is such that it protrudes and is vertically continuous at the protruding tip side. Therefore, the base member 801 of the game nail exchanging tool 800 has a shape having a U-shaped portion in a side view as a recessed portion 533 for a game plate, which is a recessed portion having a deeper depth than the upper portion where the operation recessed portion 532 is formed. Has been done. When compared with the base member 511 in the above-described embodiment, the base member 801 includes only two projecting portions 544 and 545 that form an operating-side projecting portion, a receiving-side projecting portion 543, and a portion that connects these projecting portions 543 to 545. Can reduce the weight of the base member 511, and by limiting the outer shape to the minimum necessary functional parts, the game nail exchanging tool 800 is formed in a small size and attached to the game board. It is possible to minimize the possibility that the game nail changer 800 collides with peripheral parts and the like. In terms of operability, by gripping a vertically continuous main body portion 802 corresponding to the bottom side portion of the game board recessed portion 533, it is possible to stably move by placing a finger on the U-shaped inner surface. It is possible to achieve high operability by reducing the weight with the minimum required shape.

The width W and the depth D of the game board recessed portion 533 need to be formed wider than the sum of the thickness of the game board, the amount of protrusion of the game nail toward 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 5 mm or more. It is preferable to set it to about 40 mm or more with a margin. When using a thicker game plate or when the amount of protrusion of the game nail toward the front side is set to be large, the width W of the game plate recessed portion 533 is set to be wide according to the increased amount.

As for the depth D of the recessed portion 533 for the game plate, it is possible to secure a long continuous range in the depth direction side (right side of FIG. 21) without decreasing the width W. It is possible to replace the game nail attached to the game plate. It is preferable because the range can be expanded. For example, the depth D of the game plate recessed portion 533 should be set within the range of approximately 60 mm to approximately 150 mm with respect to the central axis of the operating member 512, as the length in the depth direction where the width dimension does not decrease. Is preferable, and it is preferable to set it in the range of approximately 70 mm to approximately 100 mm. As the depth D of the game board recess 533 is longer, the outer shapes of the base members 501 and 801 are separated from the central axis of the actuating member 512, and the insertion operation into the opening 50a (see FIG. 18) of the center decoration member can be performed. Since it becomes difficult or impossible, it is preferable to set the depth D of the game plate recess 533 to a size equal to or less than the above-mentioned value so as 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 actuating member 512 toward the distal end side (the lower side in FIG. 21) in the moving direction. As shown in FIG. 21, the adjustment spacer 811 is arranged between the rotation operation member 518 and the end surface of the base member 801 with which the rotation operation member 518 contacts, and is slightly smaller than the outer shape of the base end side support member 517. It is composed of an annular metal member having a large inner diameter. The thickness of the adjusting spacer 811 along the central axis of the actuating member 512 limits the movement of the actuating member 512 toward the distal end side (the lower side in FIG. 21) in the inserting direction. By this adjusting spacer 811, the amount of protrusion of the game nail to the front side can be further increased in the inserting operation, and by providing the adjusting spacer 811 corresponding to the change of the thickness of the game board, the game board having a different thickness can be provided. It can be a corresponding game nail changer. It should be noted that the screwing amount of the fixed operation member 519 with respect to the rotation operation member 518 may be adjusted to serve as position adjusting means, and the fixed 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 distal end 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 a position adjusting means, and the game nail can be inserted. The position can also be set by loosening the fixing screw 521 and then adjusting the relative position along the axial direction of the rotation operation member 518 with respect to the base end side support member 517.

Instead of at least one of the extrusion support member 561 and the insertion support member 571 in the above-described embodiment, for example, as shown in FIGS. 22A and 22B, the extrusion support having a different tip end shape. At least one of the member 821 and the insertion support member 831 may be a component of the game nail exchange tool. 22A is a side view of the pushing support member 821 according to another embodiment, FIG. 22B is a side view of the insertion support member 831 according to another embodiment, and FIG. 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 insertion support member 839 in other embodiment.

The extruding support member 821 and the inserting support member 831 have distal end portions 822 and 832 formed longer than those of the extruding support member 561 and the inserting support member 571 in the above-described embodiment, and as shown in FIG. The length is set such that the gaming board 50 can be sandwiched between the receiving member 513 and the receiving member 513. That is, in the pushing support member 821, as shown in FIG. 22A, the male screw portion 584 and the knob portion 586 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 to be approximately equal to the length obtained by adding the length of the spacer 522 to the portion 585.

The shape of the tip end portion 822 of the pushing support member 821 is a substantially spherical shape in which the portion contacting the game plate on the tip end side where the receiving member 513 is located is arcuate in side view and the central portion is the most bulged toward the receiving member 513 side. It is formed in a substantially hemispherical shape. As shown in FIG. 22D, the tip end portion 822 of the pushing support member 821 has a through hole in the central portion and is located at a position close to the center of the receiving member 513 which abuts the back surface of the game board 50 in an annular shape. It is set to abut on the game board 50. Therefore, when the tip of the pushing support member 821 is advanced to the game plate 50 side, a force acts near the center of the receiving member 513, and the gaming plate 50 is placed between the receiving member 513 and the pushing support member 821. It is possible to easily and accurately carry out the operation of sandwiching.

The length L1 from the grip portion 586 to the tip of the tip portion 822 in the pushing support member 821 is set to be the pushing support member in a state of being sandwiched between the game plate 50 to which the game nail to be replaced is fixed and the receiving member 513. Both 821 and the receiving member 513 are set to a length such that they 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 this case, the length L1 from the pick portion 586 to the tip of the tip portion 822 may be determined with reference to the thinnest gaming plate.

Also in 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 grip portion 596 to the tip of the tip end portion 595 of the insertion support member 831 is the insertion support member 831 when the game plate 50 to which the game nail to be replaced is fixed is sandwiched in the front and rear. The receiving member 513 and the receiving member 513 are both set to a length that allows the abutting contact with the game board 50.

Regarding the shape of the tip portion 832 of the insertion support member 831, the portion of the tip end side where the receiving member 513 is located is in contact with the game plate is arcuate in side view, and the central portion is the most bulged toward the receiving member 513 side. It is formed in a substantially spherical shape (a substantially hemispherical shape). As shown in FIG. 22D, the tip end 832 of the insertion support member 831 has the insertion support member 831 at a position close to the central portion where the receiving member 153 comes into contact with the back surface of the game plate 50 in an annular shape. The tip is set to abut, and the operation of sandwiching the game board 50 between the receiving member 513 and the inserting support member 831 can be easily and accurately executed.

Here, an operation of sandwiching the game board 50 between the receiving member 513 and the pushing support member 821 and the insertion support member 831 will be described with reference to FIGS. 22(c) and 22(d). 22C and 22D show a state in which the gaming board 50 cut in the vertical direction is viewed from the side, and after the orientation adjustment of the receiving member 513 is finished, the pushing support member 821 (or the difference). Shows a process of operating the insertion support member 831) to rotate and insert the game board 50 between the receiving member 513 and the pushing support member 821 (or the insertion support member 831) and the state after the operation. There is.

For example, an operation of attaching the insertion support member 831 to the game nail exchanging tool 500 and sandwiching the game plate 50 between the insertion support member 831 and the receiving member 513 will be described. First, as shown in FIG. 22C, the tip 832 of the insertion support member 831 is brought into contact with the game plate 50 while being aligned with the nail hole into which the game nail formed in the game plate 50 is to be inserted. Let In this case, since the central portion of the tip end portion 832 of the insertion support member 831 projects most toward the receiving member 513 side, the tip end portion tapered toward the tip end side may be aligned with the nail hole. The center of the tip end portion 832 of the insertion support member 831 can be easily aligned by making it easy to confirm the hole. Further, even if the tilt angle of the game nail exchanging tool 500 changes after the insertion support member 831 is aligned, the positional deviation between the central axis of the tapered tip portion 832 and the nail hole can be suppressed to be small. You can Therefore, the tilt angle of the game nail changer 500 can be easily adjusted.

After the position of the distal end portion 832 of the insertion support member 831 is adjusted, the insertion support member 831 is rotated toward the receiving member 513 side (the arrow direction side in FIG. 22C). If this rotation operation is continued, a part of the receiving member 513 contacts the back surface of the game board 50, and if the rotation operation is further continued, 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 plate 50 side and the back surface of the game plate 50 is reduced. Further, by rotating the insertion support member 831, as shown in FIG. 22D, the gap between the surface of the receiving member 513 facing the gaming plate 50 side and the back surface of the gaming plate 50 disappears, and the insertion member is inserted. The game nail exchanging tool 500 is arranged at an appropriate inclination angle in which the inserting direction of the game nail, which coincides with the direction in which the tip portion 832 of the supporting member 831 continues, and the penetrating direction of the nail hole coincide with each other.

In the middle of inclining the game nail exchanging tool 500, a position where the tip end portion 832 of the insertion support member 831 contacts the game plate 50 and a portion of the receiving member 513 contact the game plate 50 are separated from each other. It is preferable that the center portion of the tip end portion 832 of the insertion support member 831 be most protruded toward the receiving member 513 side. In the case of this shape, the game nail exchanging tool 500 is easily transitioned to an inclined state around the center of the tip portion 832 of the insertion support member 831, and the game nail exchanging tool 500 is moved to an appropriate inclination angle side. It can be easily tilted. Further, while a part of the outer circumference of the annular receiving member 513 abuts on the back surface side of the game plate 50, a force acts near the center of the receiving member 513 on the front surface side of the game plate 50 for insertion. By the rotation operation of the support member 831, the turning force easily acts in the direction in which the entire game nail exchanging tool 500 is inclined at an appropriate inclination angle. Therefore, 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 plate 50 side and the back surface of the game plate 50 is eliminated. The game nail exchanging tool 500 can be accurately arranged in a state in which it can be inserted into the nail hole to be operated. Further, when performing the rotation operation of the insertion support member 831, the more the game plate 50 and the insertion support member 831 are in contact with each other at a position closer to the rotation center of the insertion support member 831, The rotation resistance torque due to the frictional force due to the contact between the insertion support member 831 and the game board 50 is small, and the rotation operation of the insertion support member 831 becomes easy. Further, even if a scratch occurs due to friction between the insertion support member 831 and the game plate 50, the scratch is formed near the base of the game nail, so that between the game nails of the game plate 50. It is possible to suppress a reduction in the visibility of the decorative portion provided on the back surface side of the game board 50 that is visible through the decorative portion or the game board 50 that has been applied. The shape of the tip end portion 822 of the pushing support member 821 is also the shape most protruding toward the receiving member 513 side, and therefore, the same effect as the operation of sandwiching the game plate 50 with the insertion support member 831 is achieved. Can be

The tip end shapes of the tip end portions 822 and 832 of the pushing 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 surface shape in which the central portion bulges toward the receiving member 513 side. .. For example, the tip shapes of the tip portions 822 and 832 may be formed in a curved shape in which a plurality of radii of curvature are combined. Further, as the tip shapes of the tip portions of the pushing support member and the insertion support member, the central portion of the tip portion 832 projects toward the receiving member 513 side with respect to the plane perpendicular to the continuous direction of the tip portion 832, and the peripheral portion. May have a shape having an inclined surface that is linearly inclined in a side view. The inclined surface may be a substantially truncated cone shape having a through hole formed in the central portion with respect to the substantially conical shape, or a substantially polygonal pyramid trapezoid having a through hole formed in the central portion with respect to the substantially polygonal pyramid. Also, in the case of a substantially polygonal pyramid, a regular hexagonal pyramid or a regular octagonal pyramid, for example, a regular polygonal truncated pyramid having at least five or more corners is used as the extrusion support member and the insertion support member. This is preferable in that the rotating operation of can be smoothly performed.

For example, as the insertion support member 839 in which the tip end surface shape of the tip end portion 832 is different from that of the insertion end support member 831, as shown in FIG. 22E, the tip end portion 832 is perpendicular to the continuous direction of the tip end portion 832. 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. The angle A1 in this case coincides with the angle at which the nail hole is attached with an inclination with respect to the thickness direction of the game board 50, that is, the inclination angle with which the game nail is attached with an inclination with respect to the direction in which the front surface of the game board 50 faces. It is preferable to set the angle larger than the tilt angle. It is possible to achieve the above-described effect by bringing the vicinity of the center of the tip end surface 839a of the insertion support member 839 into contact with the front surface of the game board. Further, an angle A1 in which the tip end surface is inclined with respect to a plane perpendicular to the continuous direction of the tip end portion 832 is an inclination angle at which the game nail is attached to be inclined with respect to the direction in which the front surface of the game board 50 faces (for example, approximately 5 degrees). ), the operation feeling of the inserting support member 831 and the game when the game nail exchanging tool 500 is arranged at an appropriate inclination angle and the situation where the inserting support member 831 is rotated. The feeling of supporting the nail changer 500 is different. Therefore, it is possible to more easily arrange the game nail exchange tool 500 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 834 formed larger than the outer shape of the head of the game nail. It is set shorter than the amount of protrusion 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 as a length shorter than this amount of protrusion, Further, it may be set sufficiently shorter than the amount of protrusion on the front side of the game nail, for example, 3 mm or more. After fixing the game nail to the game board, it is necessary to pull out the game nail through the through groove 833, so the length L3 of the through groove 833 to the opening 834 is set to be smaller than the amount of protrusion of the game nail toward the front side. To be done. When inserting the game nail, the game nail is supported with the head of the game nail being supported at the entrance side (upper side of FIG. 22B) where the through groove 833 is not formed in the base end side support hole 835. Since it advances into the game board 50, the head of the game nail does not move to the side of 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 having a surface hardness softer than the surface hardness of the game board 50, or It is preferable to perform a surface treatment or the like such that a surface portion softer than the surface hardness of the game board 50 is formed on at least the tip end side surfaces of the tip end portions 822, 832. For example, when the game board 50 is made of polycarbonate or acrylic, a material containing polypropylene or elastomer having a surface hardness softer than the material of the game board 50 is used, or at least the tips 822 and 832 are made of the soft material. It is preferable to form the tip. It is possible to suppress scratches when the tip ends 822 and 832 of the pushing support member 821 and the insertion support member 831 abut against the surface of the game board 50 and rub against it.

Instead of the insertion support member 571 in the above-described 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 located closer to the long groove portion 602 than the circular opening 601. The insertion support member 841 having a continuous shape may be used. 23A is a side view of the insertion support member 841 according to 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 mounting support member 841. Note that FIG. 23(b) and FIG. 23(c) also show the game nail, and FIG. 23(c) schematically shows the insertion actuating member 572.

The base end side support hole 842 is formed with an inner diameter slightly larger than the head of the game nail, and is closer to the tip side (the lower side of FIG. 23(a)) in the insertion direction of the game nail than the circular opening 601 in the through groove 599. It continues until. The long groove portion 602 which is continuous with the opening 601 in the through groove 599 is a portion formed to be thinner than the head portion of the game nail and thicker than the shaft portion. For example, the width of the long groove portion 602 is about 1 when the game nail shaft portion is formed. When it is 0.85 mm, it is set to about 3 mm. The opening 601 is a portion formed to be 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.

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

The length X1 of the section that is continuous from the opening 601 to the tip side in the insertion direction of the game nail in the base end side support hole 842 is when the insertion amount S is the insertion amount of the game nail to the front surface of the game plate. , Longer than the insertion amount S. Therefore, as shown in FIG. 23B, the tip of the game nail is brought into contact with the game board in a state where the head of the game nail is located closer to the long groove 602 than the opening 601 and the game nail is moved to the game board. Even when the game nail is inserted into the game board, the head of the game nail can move within the range where the base end side support hole 842 is formed and can be sufficiently inserted into the game board. In the base end side support hole 842, the length X1 of the section continuous from the opening 601 to the tip side in the insertion direction of the game nail is, for example, approximately 10 mm which is larger than the insertion amount S when the insertion amount S is approximately 5 mm. Is set. By this setting, as shown in FIG. 23(c), the opening 601 of the through groove 599 is closed at the tip of the insertion actuating member 572, and the insertion actuating member 572 is advanced to play the game. It is possible to insert a nail and prevent the game nail from dropping through the through groove 599.

Here, as the length X1 of a section that is continuous from the opening 601 to the tip side in the insertion direction of the game nail in the base end side support hole 842, the amount by which the game nail is inserted into the front surface of the game plate is calculated from the insertion amount S. You may set it to a small length. Even in this case, as shown in FIG. 23C, it is possible to form a state in which the opening 601 of the through groove 599 is closed at the tip end portion of the insertion actuating member 572, and the insertion support member 571. It is possible to prevent the game nail from dropping after the game nail is arranged inside the.

The length X2 from the opening 601 of the through groove 599 to the tip end side of the insertion direction of the game nail at the tip of the insertion support member 841 is a game through the through groove 599 after the game nail is fixed to the game board. It is set to be shorter than the protruding amount 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 plate 50 has a circular cross section, but it does not necessarily have to have a circular cross section, and a non-circular polygon or a star is used as the cross-sectional shape that provides the pulling force. It may be formed in another shape such as a shape. Further, the nail hole 52 does not necessarily have to be formed as a through hole, and may be formed as a non-through hole in which only the front surface side of the game board 50 is open and the rear surface (back surface) side is closed. However, when the game nail 100 is broken, the hole of the inner diameter that holds the holding portion 111 penetrates to the back surface side so that the game nail 100 can be pushed out to the back surface side and pulled out. Is preferred. As a result, when the game nail 100 is broken, the inner surface of the nail hole 52 is less likely to be scraped as compared with the case where the remaining portion of the game nail 100 is pulled out to the surface side, and the game nail 100 is replaced with a new game nail. It is possible to increase the holding power for pulling out.

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, for example, from the front surface side with respect to the opening of the game board 50. It is preferably fixed in a removable manner. When the game nail 100 that has been broken as described above is pushed out to the back side of the game plate 50 and pulled out, a part is arranged before and after the game plate 50 through the opening of the game plate 50, for example, a U-shape in side view. It is possible to arrange a dedicated tool for. Specifically, a shaft-shaped member that is movable so as to project to the part located on the back side is provided at the part located on the front side of the tool, and the game nail 100 broken by the member is used as the game board 50. Please push out from the front side. The game nail 100 provided on the upper side of the start winning opening 25 or in the vicinity thereof or the passage of the game ball is provided in the center decoration member 22 to guide the upstream side away from the starting winning opening 25 to the portion directly above the starting winning opening 25. In the vicinity of the center decoration member 22 such as the entrance portion of the passage in such a case, many game nails 100 that have a high contact frequency of game balls and have a high influence on the result of a game such as a prize are arranged. The nails need to be arranged at a predetermined position and at a predetermined angle so that the game balls can be 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 the game plate 50 is transparent to the game nail 100, the opening of the game plate 50 provides the front surface 51 of the game plate 50 with a small dedicated tool. The holding force for pulling out the game nail 100 when the game nail 100 is pushed out from the side to the back side and replaced with a new game nail can be maintained high.

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 a portion near the holding portion 111 having high bending stress, and this broken game is broken. A part of the tip side of the nail 150 is likely to remain in the thickness range of the game board 300, that is, in the nail hole 302. When pushing out the remaining game nail 150 to the back surface side of the game board 300 and inserting a new game nail 150, the front surface 301 side of the game board 300 inside the nail hole 302 remains when pushing out the broken game nail 150. Since the game nail 150 is not rubbed at all, the portion is not scraped, and the holding force for pulling out the game nail 100 when replaced with a new game nail can be easily made high.

In each of the above-described embodiments, the holding portion 111 is configured by the two thread shapes protruding to the outer peripheral surface side, but it is not necessarily required to have the two thread shapes, and may be one thread or three threads or more. If the shape is such that the pull-out force can be obtained, the cross-sectional shape is not twisted along the axial direction, a net-shaped or striped knurled shape or a large number of protrusions parallel to the axial direction are provided in the circumferential direction. It may be a holding portion having a cross-sectional shape with irregularities on the surface.

However, it is not necessary to set the protrusion amount, but it is preferable that the protrusion amount is within a range of approximately 0.1 mm or more and 0.5 mm, and it is preferable that the protrusion amount is within a range of approximately 0.2 mm to approximately 0.4 mm. Is. Further, when the game nails 100, 150 are attached to the game plates 50, 200, 300 while being inclined upward, the protrusion amount of the hard portion is the smallest in the upper portion, and therefore the above-mentioned in the smallest portion. It is preferable to set the protrusion amount.

In each of the above embodiments, the holding portion 111 and the constricted portion 152 as the hard portion are formed to be harder than the abutting portion by the plastic deformation due to the processing when forming the outer shape, but they are not necessarily formed harder when processing the shape. The hard portion may be formed by another method. For example, the surface may be hardened by a process such as shot peening that causes a small-diameter iron ball to collide with the surface to harden the surface, or it may be located in front of and behind the front surface of the game board in the shaft portion of the game nail. The surface may be hardened by forming a film or layer of a metal harder than brass as a base material in the range by vapor deposition or the like. The boundary between the holding part 111 or the constricted part 152 as the hard part and the part that is not the hard part is formed so that the ridge line is clearly projected or the surface color is changed so that the boundary line can be seen at a glance. It is preferable to make it different so that the boundary line can be confirmed. As a result, the positional relationship between the edge part of the nail holes 52, 202, 302 on the front side of the game plates 50, 200, 300 and the boundary line can be confirmed. It can be easily confirmed, and the appearance can be improved by overlapping the edge portion and the boundary line. The front surface of the game board is a combination of the inner diameters of the nail holes 52, 202 and 302 and the outer diameter of the holding portion 111 so that the tightening margin or pulling force different from the tightening margin or pulling force in each of the above embodiments is obtained. A part of the hard portion may be slightly projected to the side, and even in this case, the adjustment work of the game nail on the resin game board can be suitably performed. In addition, a colored sheet-shaped decorative plate (cell plate) is placed on the front side of the resin game board, or an opaque resin game board is used, and the inside of the nail hole is inserted from the front side of the game board. The tip portion of the inserted game nail may be invisible, and in this case, it is possible to make it easy to visually recognize a part of the protrusion of the holding portion 111 as a hard portion protruding from the front surface of the game plate. Is preferable.

In each of the above-described embodiments, the holding portion 111 as the hard portion or a part of the constricted portion 152 is configured to project to the front side from the front surface of the game plates 50, 200, 300, but it is not always necessary to adopt this configuration. By setting the tightening margin or withdrawal force while arranging the hard part completely inside the nail holes 52, 202, 302, the behavior of the game ball in the resin game board is preferable. It is possible and preferable.

The specific portion 61 in which the specific game nail 100a in each of the above-described embodiments is provided is not limited to the portion in the above-described embodiment, and may be another portion. In this case, the inclination is large for adjusting the angle of the game nail, or the game ball. It is preferable to set the part that frequently contacts or the game ball contacts at high speed as the specific part. Further, regarding the engaging structure in which the game nails and the nail holes in which the game nails 100 and 150 and the nail holes 52, 202 and 302 in each of the above embodiments are engaged, the engaging structure of 1 described in each of the above 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 by dividing the specific game nail 100a and the general game nail 100b. It is also possible to apply three or more types of engagement structures to one pachinko machine.

The present invention may be applied to a pachinko machine or the like of a type different from the above embodiment. For example, once a big hit occurs, it may be implemented as a pachinko machine in which the expected big hit value is increased until a big hit state including the big hit occurs a plurality of times (for example, twice or three times). Further, it may be carried out as a pachinko machine which is in a special game state on condition that a ball is won in a predetermined area after the jackpot pattern is displayed. Further, it may be adopted as a so-called ordinary machine without a lottery function such as a big hit. It may be implemented as a pachinko machine that enters a special game state when a ball enters a predetermined winning opening. Alternatively, it may be implemented in an enclosed pachinko machine in which balls circulate. Further, in addition to the pachinko machine, various kinds of game machines such as arrangement ball type pachinko machines and sparrow balls may be implemented.

The features of the invention group extracted from the above-described embodiments will be described below, showing effects and the like as necessary. It should be noted that, in the following, for ease of understanding, the configurations corresponding to the above-described embodiments are appropriately shown in parentheses or the like, but the present invention is not limited to the specific configurations shown in brackets or the like.

<Feature A group>
Conventionally, there is a pachinko machine as a typical example of a game machine. The pachinko machine includes, for example, a game board that forms a game area in which the game balls flow down, and in the game area, a winning opening from which the game balls are paid out when the game balls are won and a game ball is guided to the winning opening. A large number of game nails that form a passage and a passage leading to the outlet without winning the prize are provided. A large number of game nails are driven and fixed to a game board that forms the outer shape of the game board. For this game board, wood such as veneer was used before, and in recent years, resin board materials or molded products. Is also used. In particular, by using a game board made of transparent resin, it is possible to make the decorative member such as a light emitting element 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 ever before. (For example, see JP-A-2008-161638).

However, the game nail nailed into the resin game board has a different feel for adjusting the game nail compared to the game nail nailed into the wooden game board, and cannot be adjusted as usual. However, there is a problem that the game nail will break if the adjustment is done too much.

<Feature A1>
A game board made of resin (game boards 50, 200, 300) in which the game balls flow down on the front side, and game nails (game nails 100, 150) provided so that the front surface of the game board faces forward. 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 the projecting end portion protruding to the front side and an outer diameter smaller than the outer diameter of the head. With a shaft portion (shaft portion 101, 151) formed to a length, the shaft from the front side of the game board with respect to a hole portion (nail holes 52, 202, 302) preformed in the game board. The part is inserted and held on the game board,

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

Also, since the hard part is slightly projected from the front surface of the game board, it is easy to see whether the game nail is in the specified position by visually recognizing the boundary position between the hard part and the part softer than the hard part. Can be confirmed, and it is possible to easily manage the game nail at the prescribed position. Also, in the case of a transparent game board, even if a part of the hard part projects forward from the front surface of the game board, the amount of projection is small, and the entire hard part from the front surface of the game board. Since the hard portion can be seen through even on the back side, there is no great difference in appearance with the hard portion completely entering the back side from the front surface of the game board. Therefore, while the appearance as a gaming machine can be made equal to that of the conventional gaming machine using the resin gaming board, it is possible to make the gaming machine easy to manage the gaming nail at the specified position, and the gaming nail adjusting work is more suitable. Can be done.

The slight protrusion of the hard portion in the characteristic A1 may be a small amount of approximately one fifth or less of the length of the hard portion along the axial direction of the shaft portion. With such a configuration, the gaming machine can be easily adjusted while maintaining high durability such as the fatigue strength of the gaming nail due to the formation of the hard portion.
