The second starting hole 64b is also one of the winning holes through which two balls are paid out as prize balls when the balls enter.

Further, the prize winning port unit 64 is provided with the ordinary electric terminal 64c as described above. The ordinary electric member 64c is mainly composed of a rotating plate and a rotating solenoid (not shown) that drives the rotating plate to open and close.

The main controller 110 (see FIG. 2) of the first embodiment normally maintains the rotating plate of the normal electric part 64c in an upright state, and covers both the left and right sides of the second starting port 64b in a front view, This prevents the balls from flowing into the second starting port 64b. When a win is won in the variable display of normal symbols, the rotating solenoid (not shown) is driven for a predetermined time, and the rotating plate of the normal electric member 64c is kept in an upright state for a predetermined time. is driven to an open state (tilted state) tilted at a predetermined angle (for example, 45 degrees) to both left and right sides to allow the ball to flow into the second start port 64b, and the winning port unit is played left-handed. 64 in front view left side or front view right side, or right-handed balls flowing down the front view right side of the winning opening unit 64 are likely to enter the second starting opening 64b, i.e., a winning assisting state. It is configured.

The normal symbol display device 83 performs variable display by alternately lighting a symbol "O" and a symbol "X" as display symbols (normal symbols) each time the ball passes through the through gate 67. - 特許庁In the pachinko machine 10, when the variable display on the normal symbol display device 83 stops at a predetermined symbol ("○" symbol in the first embodiment), the normal electric parts 64c provided on both the left and right sides of the second start port 64b is activated for a predetermined period of time, and when it stops at a symbol other than a predetermined symbol (symbol "x" in the first embodiment), the normal electric part 64c is deactivated (the closed state is maintained). It is

Below the winning opening unit 64 in a front view, a large winning opening 65a having a horizontally elongated rectangular shape is provided substantially in the center of the variable winning device 65. As shown in FIG. In the pachinko machine 10 of the first embodiment, when the lottery of the first special symbol or the second special symbol in the main controller 110 (see FIG. 2) becomes a big hit, after a predetermined time (fluctuation time) has passed, The second LED group 37b of the special symbol display device 37 is lit and displayed so that the stop symbol of the big win is displayed, and the stop symbol corresponding to the big win is displayed on the third symbol display device 81 (for example, three identical symbols ("777 etc.)) is displayed to indicate the occurrence of a jackpot game. After that, in the jackpot game, a jackpot opening/closing plate (not shown) provided in the variable prize winning device 65 is opened, and the game state is changed to a special game state (jackpot game) in which the ball easily enters the jackpot 65a. transitions. In this special game state, the large winning opening 65a, which is normally closed, is opened until a predetermined condition is satisfied (for example, until "30 seconds" have elapsed since the opening of the large winning opening 65a, or until 10 balls are played). (until you win a prize).

When the large winning opening 65a is opened, it is closed when a predetermined time elapses from opening or when a predetermined number of winnings is detected, and after that closure, the large winning opening 65a is opened again. The opening and closing operation of the big winning opening 65a can be repeated up to, for example, 15 times (15 rounds). The state in which this opening and closing operation is performed is one form of a special game state (jackpot state) that is advantageous to the player, and the player can win the game by winning the ball into the big winning hole 65a. As a value (game value) is given, a larger amount of prize balls than usual is paid out.

Affixing spaces K1 and K2 for affixing certificate stamps, identification labels, etc. are provided at the left and right corners on the lower side of the game board 13. can be viewed through a small window 35 (see FIG. 1).

Furthermore, the game board 13 is provided with an out port 66 . Balls that do not enter any of the winning openings (entrance openings) 63, 64a, 64b, 65a are guided through an out opening 66 to a ball discharge path (not shown).

A large number of normal nails 200 and mini-head nails 300 are planted (upright) on the game board 13 in order to appropriately disperse and adjust the falling directions of the balls flowing down each area of the game area. , various members (accessories) such as a windmill 71 as an obstacle member are arranged. The windmill 71 is rotatably supported (implanted) on the board surface of the game board 13, and when the ball collides with a guide plate (not shown), which will be described later, a rotating shaft provided on the front side of the guide plate will rotate. The plate rotates either clockwise or counterclockwise. When the windmill 71 rotates clockwise, the balls are easily distributed to the right side of the game board 13 when viewed from the front. 13 is configured to facilitate distribution of balls in the left direction when viewed from the front. Further, on the back side of the windmill 71, there is provided a guide plate that guides (rebounds) the ball that collides with the windmill 71 toward the board surface of the game board 13, and the ball collides with the guide plate. By bouncing back to the board surface side of the game board 13, the balls flowing down the game area are configured to easily flow down along the board surface of the game board 13. - 特許庁A pinwheel nail (not shown) for attaching the pinwheel 71 to the game board 13 is not provided with a threaded portion 205 like the common nail 200 described later. Therefore, even when the windmill 71 is pulled out from the game board 13 side, the nail hole 13a of the game board 13 is not damaged, and the windmill nail can be driven into the nail hole 13a again. ing.

On the board surface of the game board 13, as described above, two types of nails, the normal nail 200 and the mini-head nail 300, are planted in each area (area) of the game area. (not shown)) where the ball first collides when it enters the game area, and the first guide nail area YK1 (so-called top nail planting area) and the left side of the variable display unit 80 when viewed from the front. A second guide nail area YK2 (so-called side nail planting area) that can collide with the windmill 71, a third guide nail area YK3 (so-called cross nail planting area) that can cause the ball to flow down toward the windmill 71, and the windmill. A fourth guide nail area YK4 (so-called road nail planting area) capable of guiding the ball guided to the left side of the game board 13 in front view by 71 toward the winning hole unit 64, a variable display device unit 80 and a winning hole. A fifth guide nail area YK5 (so-called navel nail implantation area) between the unit 64 (first starting port 64a) and capable of guiding the ball toward the first starting port 64a, and a general prize A sixth guide nail area YK6 capable of guiding the ball toward the mouth 63 is formed, and an ordinary nail 200 or a mini nail 200 is provided for each area YK1 to YK6 in order to appropriately disperse the ball that has flowed down to each area YK1 to YK6. A head nail 300 is implanted.

In the pachinko machine 10 of the first embodiment, normal nails 200 are provided in the first guide nail area YK1, the second guide nail area YK2, the third guide nail area YK3, the fifth guide nail area YK5, and the sixth guide nail area YK6. are planted respectively, while a mini-head nail 300 is planted in the fourth guide nail area YK4.

Details of the normal nail 200 and the mini-head nail 300 will now be described with reference to FIG. 4(a) is a front view and a side view of a normal nail 200, and FIG. 4(b) is a front view and a side view of a mini-head nail 300. FIG.

First, as shown in FIG. 4(a), the normal nail 200 is formed with a total length of about 33 millimeters (millimeters are abbreviated as "mm" hereinafter). The ordinary nail 200 is made of a brass material having a Vickers hardness of 150 Hv to 230 Hv or a metal having a Vickers hardness of 150 Hv to 230 Hv. It is structured so that it does not easily rust, and is not easily broken (damaged) by the impact of the ball.

This ordinary nail 200 mainly includes an ordinary head (nail cap) 201, an ordinary shaft portion 202, an ordinary small diameter portion 203, an ordinary first parallel portion 204, an ordinary screw portion 205, an ordinary second parallel portion 206 and an ordinary pointed portion. 207, each of the parts 201 to 207 is formed continuously, and each of the parts 201 to 207 is configured to have a different diameter (cross-sectional width in the side view of the game board 13; hereinafter the same). there is

The normal head portion 201 is a portion on the free end side of the normal nail 200, and its diameter φ1 is about 4.3 mm, which is about 2.324 times the diameter φ2 of the normal shaft portion 202 described later. It is configured. The normal head part 201 has a normal head part 201a formed in a spherical shape and a normal head part 201b which can be positioned on the game board 13 side when the normal nail 200 is implanted in the game board 13. have. The normal umbrella front portion 201a includes a normal umbrella top portion 201a1 which is the center of the spherical shape, and a normal umbrella tip portion 201a2 which is a part of the outer circumference of the normal umbrella front portion 201a and continues to the normal umbrella back portion 201b. is formed. It should be noted that the normal umbrella tip portion 201a2 is chamfered in a predetermined manner (for example, it is R-shaped and has an R of 0.2 mm).

In the pachinko machine 10 of the first embodiment, for example, the standing state (inclined state) of the normal nail 200 (the same applies to the mini-head nail 300 described later) is illegally deformed (so-called nail bending goto) by a so-called goto master or the like. In this case, a person involved in the hall hits the normal head portion 201a (mini head head portion 301a) of the normal head portion 201 (mini head head portion 301) with a hammer or the like, so that the entire normal nail 200 is hit with a hammer or the like. It is configured to easily transmit an impact, and is configured to be able to correct (easily correct) the standing state of the deformed normal nail 200 (mini-head nail 300).

The normal head portion 201 is configured such that the height and width D1 of the normal head portion 201 is approximately 1.0 mm. Further, since the diameter φ2 of the normal shaft portion 202, which will be described later, is about 1.85 mm, the distance D2 from the outer peripheral portion of the normal shaft portion 202 to the normal umbrella tip portion 201a2 of the normal head portion 201 is about 1.85 mm. It is configured to be 225 mm. In other words, the normal umbrella tip portion 201a2 protrudes in the outer peripheral direction from the normal shaft portion 202 by a distance D2 (that is, approximately 1.225 mm).

As described above, the normal shaft portion 202 has a diameter φ2 of about 1.85 mm and a length (that is, from the connection portion with the normal head portion 201 to the connection portion with the normal small diameter portion 203). distance) is about 17.5 mm.

A normal tapered portion 202 a is formed in the normal shaft portion 202 at a portion that is continuous with the normal head portion 201 . This normal tapered portion 202a has a predetermined taper shape (so-called taper shape) from the normal umbrella back portion 201b to the normal shaft portion 202. 0.85 mm, taper length 0.3 mm, and taper angle of about 33.7 degrees, the diameter gradually becomes smaller.).

The normal shaft portion 202 is a part that protrudes (exposes) from the board surface side of the game board 13 when the normal nail 200 is planted in a nail hole 13a (see FIG. 5) formed in the game board 13, which will be described later. It is configured to collide with balls flowing down the game area.

The ordinary small-diameter portion 203 is a portion on the fixed end side of the ordinary nail 200, and the entire outer circumference of the ordinary small-diameter portion 203 is rounded so that the diameter of the center portion in the width direction of the ordinary small-diameter portion 203 is approximately 1.75 mm. It is formed to have a shape and is configured so that its length (that is, the distance from the connection portion with the normal shaft portion 202 to the connection portion with the normal first parallel portion 204) is about 2.0 mm. ing.

Specifically, the diameter (φ2) of the normal small diameter portion 203 on the normal shaft portion 202 side is about 1.85 mm, the diameter of the center portion in the width direction of the normal small diameter portion 203 is about 1.75 mm, and the normal diameter of the normal small diameter portion 203 is about 1.75 mm. It is formed in an R shape with an R of 10 mm so that the diameter on the 1 parallel portion 204 side is about 1.85 mm. That is, since the normal small-diameter portion 203 is formed to have a diameter smaller than that of the normal shaft portion 202 and the like, the stress applied to the normal nail 200 is less than other portions of the normal nail 200 (for example, the normal shaft portion 202 and the like). It has a weaker structure.

Therefore, if the normal nail 200 is broken (sheared) by the stress generated by the impact of the ball against the normal nail 200, the normal small diameter portion 203 is likely to break, and the fracture surface (broken portion) is likely to break. ) can be easily formed inside the nail hole 13a of the game board 13 (see FIG. 5). In other words, when the normal nail 200 is broken, the parts such as the normal shaft portion 202 are structured so as to be difficult to break, and the broken surface is hard to be formed in a state protruding toward the front side of the game board 13. It is

With this configuration, when the ordinary nail 200 is broken, the remaining portion of the ordinary nail 200 still held by the game board 13 is removed by the game board 13 (nail hole 13a (see FIG. 5)) using a dedicated jig. When pushing out from the front side to the back side of the game board 13, the tip of the special jig is inserted into the nail hole 13a of the game board 13, and the remaining part of the broken ordinary nail 200 is pushed out in a state of contact with the broken surface. It becomes possible to push out to the back side of the board 13 . As a result, when the remaining part of the broken ordinary nail 200 is pushed out from the front side to the back side of the game board 13 by the special jig, the edge of the nail hole 13a pushes the tip of the special jig out of the remaining part of the ordinary nail 200. The remaining part can be easily pushed out without being displaced from the broken surface on the side, and the remaining part of the broken ordinary nail 200 can be easily pulled out from the back side of the game board 13.例文帳に追加In addition, when the remaining portion of the broken ordinary nail 200 protrudes from the board surface of the game board 13, the tip of the dedicated jig is displaced from the broken surface of the remaining part and comes into contact with the board surface of the game board 13. Although there is a risk of damaging the board surface, it is possible to suppress damage to the board surface of the game board 13 by the tip of the dedicated jig by facilitating the formation of the fracture surface of the remaining portion inside the nail hole 13a. .

The normal first parallel portion 204 is a portion on the fixed end side of the normal nail 200, is formed continuously from the normal small diameter portion 203, and has a diameter of about 1.85 mm, similar to the normal shaft portion 202. In addition, the length (that is, the distance from the connecting portion with the normal small diameter portion 203 to the connecting portion with the normal screw portion 205) is about 2.5 mm.

The normal screw portion 205 is a portion on the fixed end side of the normal nail 200 and is formed continuously from the normal first parallel portion 204 , and a thread groove is formed over the entire normal screw portion 205 . In addition, in the normal screw portion 205, the outer diameter of the thread groove is formed with a diameter of about 2.0 mm, and the length (that is, from the connection portion with the normal first parallel portion 204 to the normal second parallel portion 206) is approximately 2.0 mm. distance to the connecting portion) is about 5.0 mm. That is, the outer shape of the normal screw portion 205 is configured to be slightly larger than the hole diameter (approximately 1.85 mm) of the nail hole 13a of the game board 13 (see FIG. 5). Therefore, when the normal nail 200 is driven into the nail hole 13a, the normal nail 200 is fixed by the frictional force generated between the normal screw portion 205 inserted into the nail hole 13a and the inner peripheral surface of the nail hole 13a. Falling off from the game board 13 is prevented.

The normal second parallel portion 206 is a portion on the fixed end side of the normal nail 200, and is formed continuously from the normal screw portion 205, and its diameter is the same as that of the normal shaft portion 202 and the normal first parallel portion 204. Approximately 1.85 mm, and the length (i.e., the distance from the connecting portion with the normal screw portion 205 to the connecting portion with the normal sharpened portion 207) is configured to be about 1.9 mm. .

The normal pointed portion 207 is a portion on the fixed end side of the normal nail 200, and is formed continuously from the normal second parallel portion 206, and the length thereof (i.e., from the connection portion with the normal second parallel portion 206) The distance to the tip of the normal pointed portion 207) is about 3.1 mm. In addition, the normal sharpened portion 207 gradually tapers from the diameter of about 1.85 mm at the connection portion with the normal second parallel portion 206 toward the distal end side of the normal nail 200 (that is, toward the non-normal head portion 201 side). It is formed in an inverted conical shape, and its tip is formed in a sharp shape. Therefore, when the normal nail 200 is driven (implanted) into the nail hole 13a (see FIG. 5), the normal sharpened portion 207 can be smoothly inserted into the nail hole 13a, and the normal nail 200 can be inserted into the nail hole 13a. can be made easier to place.

Then, as shown in FIG. 4(b), the mini-head nail 300 is formed with a total length of about 33 mm, like the normal nail 200. As shown in FIG. In addition, the mini-head nail 300 is made of a brass material having a Vickers hardness of 150Hv to 230Hv or a metal having a hardness similar to that of the ordinary nail 200, and is not easily rusted. It is configured so as not to be easily broken (damaged) by the impact of the ball.

This mini-head nail 300 mainly includes a mini-head head (nail umbrella) 301, a mini-head shaft portion 302, a mini-head small diameter portion 303, a mini-head first parallel portion 304, a mini-head screw portion 305, and a mini-head second portion. Consisting of a parallel portion 306 and a mini-head sharpened portion 307, the portions 301 to 307 are continuously formed and each portion 301 to 307 has a different diameter.

The mini-head head portion 301 is a portion on the free end side of the mini-head nail 300, and its diameter φ3 is about 2.775 mm, which is about 1.5 times the diameter φ4 of the mini-head shaft portion 302 described later. is configured to be The mini-head head 301 has a mini-head canopy front part 301a formed in a spherical shape, and a mini-head canopy that can be positioned on the game board 13 side when the mini-head nail 300 is planted on the game board 13. and a back portion 301b. The mini-head canopy front portion 301a includes a mini-head canopy top portion 301a1 which is the center of the spherical shape, and a mini-head portion which is the outer peripheral portion of the mini-head canopy surface portion 301a and continues to the mini-head canopy back portion 301b. An umbrella tip portion 301a2 is formed. Note that the mini-head canopy tip portion 301a2 is chamfered in a predetermined manner (for example, in an R shape with an R of 0.05 mm).

The mini-head head 301 is configured such that the height and width D3 of the mini-head head 301 is about 0.5 mm, which is half that of the normal head 201 . That is, the difference D5 between the height width D3 of the mini head portion 301 and the height width D1 of the normal head portion 201 is configured to be approximately 0.5 mm.

Further, since the diameter φ4 of the mini-head shaft portion 302, which will be described later, is approximately 1.85 mm, the distance D4 from the outer peripheral portion of the mini-head shaft portion 302 to the mini-head canopy tip portion 301a2 of the mini-head head portion 301 is , about 0.463 mm. In other words, the mini-head umbrella tip portion 301a2 protrudes in the outer peripheral direction from the mini-head shaft portion 302 by a distance D4 (that is, approximately 0.463 mm). That is, the difference D6 between the amount D2 of projection of the normal head portion 201 from the normal shaft portion 202 and the amount D4 of projection of the mini head portion 301 from the mini head shaft portion 302 is approximately 0.762 mm. Therefore, the mini-head nail 300 has a smaller amount of protrusion from the shaft portion 302 than the ordinary nail 200 (the amount of protrusion of the mini-head nail 300 = 0.463 mm <the amount of protrusion of the ordinary nail 200 = 1.225 mm). It is configured.

In this way, the diameter φ3 of the mini-head head portion 301 of the mini-head nail 300 is smaller than the diameter φ1 of the ordinary head portion 201 of the ordinary nail 200, so that the ordinary nail 200 can be implanted when the game board 13 is viewed from the front. The area where the board surface of the game board 13 can be visually recognized increases when the mini-head nail 300 is implanted than when the mini-head nail 300 is implanted. Therefore, in the area where the mini head nail 300 is planted, the board surface of the game board 13 can be easily visually recognized, and when a design is applied to the board surface of the game board 13, the design can be easily visually recognized by the player to make it decorative. can be improved. Further, when a role object or a display device is arranged on the rear surface of the game board 13 made of transparent resin in the planting area of the mini head nail 300, the role object or the display device can be easily recognized visually. It is possible to accurately convey to the player the movable mode of the character and the display contents of the display device, and to make it easier to see the powerful performance by the entire game board 13, thereby improving the interest of the game.

The mini-head shank 302 has a diameter of φ4 of about 1.85 mm, similar to the ordinary shank 202 of the ordinary nail 200, while its length (that is, from the connection with the mini-head head 301 to the mini-head shank) is approximately 1.85 mm. The distance to the connecting portion with the small diameter portion 303) is approximately 18.0 mm, which is longer than the normal shaft portion 202 by approximately 0.5 mm.

A mini-head tapered portion 302 a is formed in a portion of the mini-head shaft portion 302 that is continuous with the mini-head head portion 301 . Similar to the normal taper portion 202a, the mini head taper portion 302a has a predetermined taper shape (so-called taper shape) from the mini head umbrella back portion 301b to the mini head shaft portion 302. For example, the diameter of the mini head umbrella back portion 301b side is 2 0.05 mm, a diameter of 1.85 mm on the side of the mini-head shaft portion 302, a taper length of 0.3 mm, and a taper angle of about 33.7 degrees, where the diameter tapers gradually.

The mini-head shaft portion 302 protrudes (exposes) from the board surface side of the game board 13 when the mini-head nail 300 is planted in a nail hole 13a (see FIG. 5) formed in the game board 13, which will be described later. It is a part and is configured to collide with a ball flowing down the game area.

The mini-head small diameter portion 303 is a portion on the fixed end side of the mini-head nail 300, and has the same configuration as the ordinary small-diameter portion 203 of the ordinary nail 200. The entire outer periphery of the mini-head small diameter portion 303 is formed to have an R shape of about 1.75 mm, and the length (that is, from the connection portion with the mini-head shaft portion 302 to the mini-head first parallel The distance to the connecting portion with the portion 304) is about 2.0 mm.

Specifically, the diameter (φ4) of the mini-head small-diameter portion 303 on the side of the mini-head shaft portion 302 is about 1.85 mm, the diameter of the center portion in the width direction of the mini-head small-diameter portion 303 is about 1.75 mm, and the mini-head small-diameter portion 303 is formed in an R shape of R10 mm so that the diameter of the first mini-head parallel portion 304 side of 303 is about 1.85 mm. That is, since the mini-head small-diameter portion 303 is formed to have a diameter smaller than that of the mini-head shaft portion 302 and the like, the stress applied to the mini-head nail 300 is more resistant to other portions of the mini-head nail 300 (for example, the mini-head shaft 300). The shaft portion 302, etc.) has a more fragile structure.

Therefore, if the mini-head nail 300 were to be broken (sheared) by the stress generated by the collision of the ball against the mini-head nail 300, it would be broken at the mini-head small diameter portion 303. The broken surface (broken portion) is easily formed inside the nail hole 13a (see FIG. 5) of the game board 13. As shown in FIG. In other words, when the mini-head nail 300 is broken, the parts such as the mini-head shaft portion 302 are configured to be difficult to break, and the broken surface is unlikely to be formed in a state of protruding toward the front side of the game board 13. is configured to

With this configuration, when the mini-head nail 300 is broken, the remaining part of the broken mini-head nail 300 still held by the game board 13 is removed by the game board 13 (nail hole 13a (Fig. 5)))), when pushing out from the front side to the back side, the tip of the special jig is inserted into the nail hole 13a of the game board 13 and is in contact with the fractured surface of the remaining part. The remaining part of the head nail 300 can be pushed out to the back side of the game board 13. - 特許庁As a result, when the remaining portion of the broken mini-head nail 300 is pushed out from the front side to the back side of the game board 13 by the exclusive jig, the edge of the nail hole 13a pushes the tip of the exclusive jig out of the mini-head nail 300. The remaining part of the mini-head nail 300 can be easily pushed out without deviating from the fracture surface of the remaining part, and the broken mini-head nail 300 can be easily pulled out from the back side of the game board 13.例文帳に追加In addition, when the remaining portion of the broken mini-head nail 300 protrudes from the board surface of the game board 13, the tip of the special jig is displaced from the broken surface of the remaining part and comes into contact with the board surface of the game board 13. Although there is a risk of damaging the board surface, it is possible to suppress damage to the board surface of the game board 13 by the tip of the dedicated jig by facilitating the formation of the fracture surface of the remaining portion inside the nail hole 13a. .

The mini-head first parallel portion 304 is a portion on the fixed end side of the mini-head nail 300, has the same configuration as the ordinary first parallel portion 204 of the ordinary nail, and is formed continuously from the mini-head small diameter portion 303. , has a diameter of approximately 1.85 mm, similar to the mini-head shaft portion 302, and its length (that is, from the connection portion with the mini-head small diameter portion 303 to the connection portion with the mini-head screw portion 305) is approximately 1.85 mm. distance) is about 2.5 mm.

The mini-head screw portion 305 is a portion on the fixed end side of the mini-head nail 300, has the same configuration as the ordinary screw portion 205 of the ordinary nail 200, and is formed continuously from the mini-head first parallel portion 304. there is A thread groove is formed over the entire mini-head threaded portion 305, and the outer diameter of the thread groove is formed to have a diameter of about 2.0 mm. from the connecting portion to the connecting portion with the mini-head second parallel portion 306) is about 5.0 mm. That is, the outer shape of the mini-head screw portion 305 is slightly larger than the hole diameter (approximately 1.85 mm) of the nail hole 13a (see FIG. 5) of the game board 13. As shown in FIG. Therefore, when the mini-head nail 300 is driven into the nail hole 13a, it is fixed by the frictional force generated between the mini-head screw portion 305 inserted into the nail hole 13a and the inner peripheral surface of the nail hole 13a. The nail 300 is prevented from falling off from the game board 13. - 特許庁

The mini-head second parallel portion 306 is a portion on the fixed end side of the mini-head nail 300, and has the same configuration as the ordinary second parallel portion 206 of the ordinary nail 200, and is formed continuously from the mini-head screw portion 305. Its diameter is approximately 1.85 mm, similar to the mini-head shaft portion 302 and the mini-head first parallel portion 304, and its length (i.e., from the connection portion with the mini-head screw portion 305 to the mini-head The distance to the connecting portion with the sharpened portion 307) is about 1.9 mm.

The mini-head sharpened portion 307 is a portion on the fixed end side of the mini-head nail 300, has the same configuration as the ordinary sharpened portion 207 of the ordinary nail 200, and is formed continuously from the mini-head second parallel portion 306, The length (that is, the distance from the connecting portion with the mini-head second parallel portion 306 to the tip portion of the mini-head acute portion 307) is configured to be approximately 3.1 mm. Also, the mini-head sharpened portion 307 is gradually tapered from the diameter of about 1.85 mm at the connecting portion with the mini-head second parallel portion 306 to the tip side of the mini-head nail 300 (that is, the non-mini-head head portion 301 side). It is formed in an inverted conical shape with a tapered diameter, and its tip is formed in a sharp shape. Therefore, when driving (implanting) the mini-head nail 300 into the nail hole 13a (see FIG. 5), the mini-head sharpened portion 307 can be smoothly inserted into the nail hole 13a. Driving the head nail 300 can be facilitated.

In this way, the mini-head small diameter portion 303, the mini-head first parallel portion 304, the mini-head threaded portion 305, the mini-head second parallel portion 306, and the mini-head sharpened portion 307 of the mini-head nail 300 are connected to the ordinary small-diameter portion of the ordinary nail 200. 203, the first parallel portion 204, the threaded portion 205, the second parallel portion 206, and the sharpened portion 207, the nail hole 13a (see FIG. 5) of the game board 13 has the same shape. It becomes possible to form Therefore, even when a plurality of types of game nails 200 and 300 are used, the process for forming the nail holes 13a in the game board 13 can be simplified, and the manufacturing cost of the game board 13 can be reduced.

Next, with reference to FIGS. 5 to 8, the manner in which the ball collides with the normal nail 200 and the mini-head nail 300 planted on the game board 13 will be described. FIG. 5 shows the game board 13 (nail hole 13a), the mini-head nail 300 and the glass unit 16 along the VV line in FIG. It is a schematic cross-sectional view. Also, FIG. 6 is a side view of the sphere. Furthermore, FIG. 7 is a schematic side view showing balls that collide with the glass unit 16 and the common head 201 of the common nail 200, or the common head 201 and the common shaft 202, respectively. Also, FIG. 8 is a schematic side view showing a ball that collides with the glass unit 16 and the mini-head shaft portion 302 of the mini-head nail 300. As shown in FIG.

First, as shown in FIG. 5, the game board 13 is provided with a nail hole 13a which is a through hole having a hole diameter of about 1.85 mm. This nail hole 13a is formed in the same shape for both the normal nail 200 and the mini-head nail 300, as described above, and the through hole of the nail hole 13a extends five downwards from the direction perpendicular to the board surface of the game board 13. It is inclined at an angle of .theta.1 in FIG. Therefore, when the normal nail 200 and the mini-head nail 300 are planted in the nail hole 13a, the vertical direction from the board surface of the game board 13 (that is, the front direction of the pachinko machine 10) upwards by 5 degrees (in FIG. θ1) It is planted at an angle. With this configuration, the ball that collides with the normal shaft portion 202 of the normal nail 200 and the mini head shaft portion 302 of the mini head nail 300 easily rebounds toward the board surface side of the game board 13, while the ball collides with the glass unit 16 side. You can make it harder to bounce. As a result, when the ball flowing down the game area collides with the glass unit 16, it is possible to suppress the occurrence of a collision sound, and it is possible to suppress the breakage of the glass unit 16 due to the collision of the ball.

In the pachinko machine 10 of the first embodiment, when both the game board 13 and the glass unit 16 are attached to the inner frame 12 (see FIG. 1), the distance D7 from the board surface of the game board 13 (in the first embodiment, (approximately 19.9 mm).

Also, since the sphere T is formed with a diameter of about 11 mm, its radius is about 5.5 mm. That is, when the sphere T collides with the glass unit 16, the distance D8 between the point of collision and the center point of the sphere T is the radius of the sphere T=approximately 5.5 mm.

Furthermore, in the pachinko machine 10 of the first embodiment, when the front frame 14 (see FIG. 1) to which the glass unit 16 is attached is closed with respect to the inner frame 12, the rear surface of the glass unit 16 and the mini head nail 300 and A clearance is provided so that the distance D9 from the tip side (left side in FIG. 5) of the mini-head nail 300 and the ordinary nail 200 to the glass unit 16 is about 1.4 mm so that the ordinary nail 200 and the like do not come into contact with each other. A mini-head nail 300 and a normal nail 200 are planted in the nail hole 13a of the game board 13 so as to have the clearance. In the following description, for convenience of description and calculation, the implantation angle θ1 (ie, 5 degrees) of the mini-head nail 300 and the normal nail 200 is not considered. That is, it is assumed that the normal nail 200 and the mini-head nail 300 are planted perpendicularly to the game board 13. As shown in FIG.

Here, as shown in FIG. 6, since the sphere T is formed with a diameter of 11 mm as described above, its radius (distance) D8 is approximately 5.5 mm. That is, when the sphere T collides with the rear surface of the glass unit 16, the center T0 of the sphere T (a perpendicular line from the center T0 of the sphere T is the outer circumference of the sphere T) from the point of contact T1 between the sphere T and the rear surface of the glass unit 16. The distance to the intersecting point T2 is the same as D8 (that is, approximately 5.5 mm).

Further, in the pachinko machine 10 of the first embodiment, as described above, the tips of the normal nail 200 and the mini-head nail 300 are positioned about 1.4 mm away from the glass unit 16 (that is, the distance D9).

The height and width D1 of the normal head portion 201 (see FIG. 4A) of the normal nail 200 is approximately 1.0 mm. The distance from the normal head portion 201 (see FIG. 5) to the position where the normal umbrella back portion 201b and the normal umbrella tip portion 201a2 (both of which are shown in FIG. 4A) are present is D9+D1=approximately 2.4 mm. Then, at the position of D9+D1 from the glass unit 16, the vertical distance D10 from the tangent line of the point T2 to the point T3 where the perpendicular line from the tangent line of the point T2 intersects the sphere T is given by the formula {5. 5×5.5=3.1×3.1+(5.5−D10)×(5.5−D10)}, and D10=approximately 0.957 mm.

Here, as shown in FIG. 7, in the ordinary nail 200, the amount of protrusion of the ordinary head portion 201 from the outer circumference of the ordinary shaft portion 202 is approximately 1.225 mm. longer than 0.957 mm. That is, since the normal umbrella tip 201a2 of the normal head 201 protrudes from the vertical distance D10, when the ball Ta collides with the glass unit 16, it collides with the ordinary umbrella tip 201a2 of the normal head 201. When the ball Ta collides with the normal shaft portion 202, it collides with the normal umbrella tip portion 201a2 of the normal head portion 201 and does not collide with the glass unit 16. , the glass unit 16 and the shank 202 do not come into contact with each other at the same time.

Specifically, the ball Ta, which collides with the glass unit 16 at the point Ta1, does not contact the normal shaft portion 202 when it is in contact with the glass unit 16 at the point Ta1, and the normal umbrella tip portion 201a2 of the normal head portion 201 and point Ta2. Ball Tb, which collides with normal shaft portion 202 at point Tb1, does not contact glass unit 16 while it is in contact with normal shaft portion 202 at point Tb1. Contact at Tb2.

Therefore, in the place (area) where the ordinary nail 200 is planted, the ball flowing down the game area contacts the ordinary shaft portion 202 of the ordinary nail 200 as well as the ordinary cap tip portion 201a2 of the ordinary head 201. put away. The ball that collides with the normal shaft portion 202 can be expected to rebound toward the board surface side of the game board 13 according to the planting angle of the normal nail 200, but the ball that collides with the normal umbrella tip portion 201a2 Due to the chamfering process (for example, R shape and R 0.2 mm) on the portion 201a2, depending on how it collides with the normal umbrella tip portion 201a2, it may bounce back to the glass unit 16 side, It is difficult to predict the direction of rebounding, such as when rebounding toward the shaft portion 202 side, or rebounding so as to collide directly with the board surface side of the game board 13 . Therefore, when a large number of ordinary nails 200 are planted, the directionality of the ball flowing down the game area varies accordingly, making it difficult to predict. This phenomenon may hereinafter be referred to as a “slump”).

If the gauge configuration of the game board 13 is likely to cause a slump, it may become difficult to set the game performance when designing the board surface of the pachinko machine 10 . In addition, if the gauge configuration of the game board 13 is likely to cause a slump, when a so-called model test is conducted by a third-party organization (for example, the Security Electronics and Communication Technology Association), the slump prevents the winning of the winning opening 64a and the like. Excessive or insufficient, there is a risk of failing the type test. Furthermore, if the gauge configuration of the game board 13 is likely to cause a slump, the period during which the ball does not enter the winning opening 64a or the like during the game by the player becomes longer, and the dissatisfaction increases due to the stopping of the variable effect. There is a risk that it will be lost. Therefore, in the pachinko machine 10, it has been a long-standing problem to stabilize the behavior of the balls flowing down the game area, and there is room for improvement regarding the gauge configuration of the game board 13, which is less prone to slump.

In addition, in the cantilever-shaped ordinary nail 200, when the ordinary head 201, which is the tip side of the free end farthest from the game board 13 board surface, collides with the ball T, the impact load generated at the tip and the game board 13 board surface The fixed end moment obtained by multiplying the distance from the tip 201a2 to the tip portion 201a2 of the common nail 200 tends to become relatively large at the portion where the common nail 200 and the nail hole 13a are implanted (that is, the common small diameter portion 203), causing nail breakage. is the cause of

Returning to FIG. 6, the description continues. Since the height and width D3 of the mini-head head portion 301 (see FIG. 4B) of the mini-head nail 300 is formed to be approximately 0.5 mm, when the mini-head nail 300 is implanted in the game board 13 , the distance from the glass unit 16 (see FIG. 5) to the position where the mini-head canopy rear portion 301b and the mini-head canopy tip portion 301a2 (both see FIG. 4(b)) of the mini-head head portion 301 are D9+D3=approximately 1.9 mm. Then, at the position of D9+D3 from the glass unit 16, the vertical distance D11 from the tangent line of the point T2 to the point T4 where the perpendicular line from the tangent line of the point T2 intersects the sphere T is given by the formula {5. 5×5.5=3.6×3.6+(5.5−D11)×(5.5−D11)}, and D11=approximately 1.342 mm.

Here, as shown in FIG. 8, in the mini-head nail 300, the amount of protrusion of the mini-head head portion 301 from the outer periphery of the mini-head shaft portion 302 is the distance D4=approximately 0.463 mm. D11 = shorter than about 1.342 mm. That is, since the mini-head canopy tip portion 301a2 of the mini-head head portion 301 does not protrude beyond the vertical distance D11, when the ball Tc collides with the glass unit 16, it collides with the mini-head shaft portion 302 and the mini-head The ball can contact the glass unit 16 and the mini-head shaft portion 302 at the same time without colliding with the mini-head umbrella tip portion 301 a 2 of the head portion 301 .

Specifically, the sphere Tc that collides with the glass unit 16 at point Tc1 can contact the mini-head shaft portion 302 at point Tc2 while contacting the glass unit 16 at point Tc1. can not come into contact with the mini-head umbrella tip portion 301a2.

Therefore, even if the ball flowing down the game area rebounds not to the board surface side of the game board 13 but to the glass unit 16 side at the place where the mini-head nail 300 is implanted, the mini-head nail 300 does not move. It does not come into contact with the mini-head head 301 and only collides with the mini-head shaft 302 with respect to the mini-head nail 300 . With this configuration, the ball colliding with the mini-head nail 300 rebounds according to the inclination angle of the mini-head shaft portion 302 of the mini-head nail 300, so that it can easily rebound toward the board surface side of the game board 13. , the bounce direction can be more predictable. Therefore, in the planting area of the mini-head nail 300 (that is, the fourth guide nail area YK4), it becomes possible to stabilize the flowing direction of the ball by making it difficult for the slump to occur. It is possible to easily stabilize the winning rate to the winning opening 64a or the like to a desired one. As a result, it is possible to realize a gauge configuration of the game board 13 in which slump is unlikely to occur, and it becomes easy to set the game performance when designing the board surface of the pachinko machine 10. - 特許庁In addition, even in the type test by a third-party organization, it is possible to stably win prizes in the prize winning opening 64a and the like, and to make it difficult to fail the type test. Furthermore, by stabilizing the behavior of the ball flowing down the game area, it is possible to suppress the situation in which the ball does not enter the prize winning opening 64a for a long period of time, thereby preventing the player's dissatisfaction due to the stoppage of the variable performance. can be prevented.

Further, in the recent pachinko machine 10, the space on the board surface of the game board 13 is reduced due to the enlargement of the third symbol display device 81 and the installation of a large number of movable accessories. As a result, the planted area and the number of planted game nails are reduced, and even if it is desired to appropriately distribute the balls flowing down the game area, the balls may not be distributed as desired due to the effect of the small number of game nails. Therefore, by using the mini-head nail 300, it becomes possible to plant more game nails than when the normal nail 200 is planted even in a small planting space, and the balls flowing down the game area are dispersed. be able to.

In the cantilever-like mini-head nail 300, the ball T does not collide with the mini-head head 301, which is the tip side of the free end farthest from the game board 13 board surface. The fixed end moment generated in the planted portion of the mini-head nail 300 and the nail hole 13a (that is, the mini-head small diameter portion 303) due to the collision of the ball T with the mini-head shaft portion 302 near the board surface is It can be smaller than the fixed end moment when the ball T collides with the normal head 201 . Therefore, by configuring the mini-head nail 300 to be less likely to break than the normal nail 200, the number of maintenance man-hours for the game board 13 can be reduced.

Here, with reference to FIG. 9, the difference between the normal nail 200 and the mini-head nail 300 when the nails are implanted continuously like the fourth guide nail area YK4 will be described. FIG. 9(a) is an enlarged front view schematically showing a case in which ordinary nails 200 are continuously planted on the game board 13, and FIG. 9(b) shows mini-head nails 300 on the game board 13. Fig. 2 is an enlarged front view schematically showing a case of continuous implantation;

As shown in FIG. 9A, the normal nail 200 has a normal head portion 201 with a diameter φ1 of about 4.3 mm and a normal shaft portion 202 with a diameter φ2 of about 1.85 mm. there is When five of the ordinary nails 200 are implanted in the lateral direction so that the interval D12 between the ordinary heads 201 of the ordinary nails 200 is about 1.0 mm, the left end of the ordinary head 201 of the leftmost ordinary nail 200 , to the right end of the normal head 201 of the right end normal nail 200 is approximately 4.3 mm×5+approximately 1.0 mm×4=approximately 25.5 mm.

On the other hand, as shown in FIG. 9(b), the mini-head nail 300 is formed such that the diameter φ3 of the mini-head head portion 301 is approximately 2.775 mm, and the diameter φ4 of the mini-head shaft portion 302 is approximately 2.775 mm. Similar to portion 202, it is formed at approximately 1.85 mm. Therefore, when the mini-head nails 300 are implanted so that the distance D12 (i.e., the interval is 1.0 mm) within the range of about 25.5 mm when five ordinary nails 200 are implanted, the mini-head nails 300 , the distance from the left end of the left mini-head nail 300 to the right end of the mini-head nail 300 is about 2.775 mm × 7 + about 1 0 mm x 6 = about 25.425 mm. Therefore, seven mini-head nails 300 can be implanted in a space in which five ordinary nails 200 are implanted in succession.

Therefore, in the game area, in the portion where it is desired to stabilize the flowing direction of the falling ball, for example, in the fourth guidance area YK4, the mini-head nail 300 is planted and the normal nail 200 is planted continuously. By continuously implanting the mini-head nail 300, the rebounding mode of the ball is stabilized more than when the normal nail 200 is implanted. On the other hand, in the parts where it is desired to disperse the falling balls in the flowing direction, for example, in the first to third guide nail areas YK1 to YK3 and the fifth and sixth guide nail areas YK5 and YK6, ordinary nails are used. Implanting 200 causes the bounce of the balls to be random, making it easier to distribute the balls more randomly than if mini-head nails 300 were implanted. Thus, by planting the normal nail 200 and the mini-head nail 300 according to the part of the game area, it is possible to construct a well-balanced gauge.

Further, when the mini-head nails 300 are continuously implanted, more mini-head nails 300 can be implanted in the space in which the ordinary nails 200 are continuously implanted, and the ball flows down the game area. It is possible to make the flow down state more stable and easier.

As described above, in the pachinko machine 10 of the first embodiment, the mini-head nail 300 having a smaller head shape than the normal nail 200 is planted in the fourth guide nail area YK4. The mini-head nail 300 is configured so that it does not come into contact with the mini-head head portion 301 of the mini-head nail 300 at the place where it is provided, and only the mini-head shaft portion 302 collides with the mini-head nail 300 . With this configuration, the ball that collides with the mini-head nail 300 can easily rebound toward the board surface of the game board 13, and the rebound direction can be easily predicted. Therefore, in the area where the mini-head nail 300 is planted (that is, the fourth guide nail area YK4), it is possible to make it difficult for a slump to occur and stabilize the flow direction of the ball. It can be made easy to stabilize to a desired thing. As a result, it is possible to realize a gauge configuration of the game board 13 in which slump is unlikely to occur, and it becomes easy to set the game performance when designing the board surface of the pachinko machine 10. - 特許庁In addition, even in the type test by a third-party organization, it is possible to stably win prizes in the prize winning opening 64a and the like, and to make it difficult to fail the type test. Furthermore, by stabilizing the behavior of the ball flowing down the game area, it is possible to suppress the situation in which the ball does not enter the prize winning opening 64a for a long period of time, thereby preventing the player's dissatisfaction due to the stoppage of the variable performance. can be prevented.

Further, by configuring the diameter of the mini-head head portion 301 of the mini-head nail 300 to be smaller than the diameter of the normal head portion 201 of the normal nail 200, when viewed from the front of the game board 13, the diameter of the mini-head nail 300 is smaller than when the normal nail 200 is implanted. When the head nail 300 is implanted, the area where the board surface of the game board 13 can be visually recognized increases. Therefore, in the area where the mini head nail 300 is planted, the board surface of the game board 13 can be easily visually recognized, and when a design is applied to the board surface of the game board 13, the design can be easily visually recognized by the player and is decorative. can be improved. In addition, when a role object or a display device is arranged on the rear surface of the game board 13 made of transparent resin in the planting area of the mini-head nail 300, the role object or the display device can be easily recognized visually. It is possible to accurately transmit the movable mode of the character and the display contents of the display device to the player, to make the powerful performance easier to see, and to improve the interest of the game.

Furthermore, in the game area, in the portion where the falling direction of the falling ball is desired to be stabilized, for example, in the fourth guidance area YK4, the mini-head nail 300 is planted and the normal nail 200 is planted continuously. By continuously implanting the mini-head nail 300, the rebounding mode of the ball is stabilized as compared with the case of planting the ordinary nail 200.例文帳に追加On the other hand, in the parts where it is desired to scatter the falling balls in the flowing direction, for example, the first to third guide nail areas YK1 to YK3 and the fifth and sixth guide nail areas YK5 and YK6, ordinary nails are used. Implanting 200 causes the bounce of the balls to be random, making it easier to distribute the balls more randomly than if mini-head nails 300 were implanted. Thus, by planting the normal nail 200 and the mini-head nail 300 according to the part of the game area, it is possible to construct a well-balanced gauge.

Further, when the mini-head nails 300 are implanted continuously, more mini-head nails 300 can be implanted in the space when the normal nails 200 are implanted continuously. In other words, when the same number of game nails are to be planted in a predetermined area, the use of the mini-head nail 300 makes it possible to plant a plurality of game nails in a small space. Therefore, by planting a large number of mini-head nails 300 in the space, it is possible to stabilize the flow of the ball more easily, and at the same time, the area where the game nails are planted is space-saving, and the game board surface can be freely designed. degree can be improved.

Furthermore, the mini-head small diameter portion 303, the mini-head first parallel portion 304, the mini-head screw portion 305, the mini-head second parallel portion 306, and the mini-head sharpened portion 307 of the mini-head nail 300 are connected to the ordinary small-diameter portion 203 of the ordinary nail 200. , the first parallel portion 204, the screw portion 205, the second parallel portion 206, and the sharpened portion 207, thereby forming the nail hole 13a (see FIG. 5) of the game board 13 in the same shape. It becomes possible to Therefore, even when a plurality of types of nails 200 and 300 are used, the process for creating the nail holes 13a in the game board 13 can be simplified.

Further, by using the mini head nails 300, it is possible to plant a large number of game nails even in a small planting space on the board surface of the game board 13, and to disperse the balls flowing down the game area. .

<Second embodiment>
Next, a pachinko machine 10 of a second embodiment to which the present invention is applied will be described with reference to FIG. In the pachinko machine 10 of the first embodiment, mini-head nails 300 are used as the game nails planted in the fourth guide nail area YK4, which are so-called road nails. On the other hand, in the pachinko machine 10 of the second embodiment, both ends of one unit of the lead nail planted in the fourth guide nail area YK4 are composed of ordinary nails 200, and the remaining lead nails are mini-head nails. 300.

The pachinko machine 10 of the second embodiment will be described below, focusing on the differences from the pachinko machine 10 of the first embodiment. In the following description of the pachinko machine 10 of the second embodiment, the same configuration and processing as those of the pachinko machine 10 of the first embodiment are assigned the same reference numerals as those of the first embodiment, and the description thereof will be omitted.

FIG. 10(a) is a front view of the game board 13 of the pachinko machine 10 of the second embodiment, and FIG. 10(b) is an enlarged front view of the fourth guide nail area of FIG. 10(a). In the pachinko machine 10 of the second embodiment, in the fourth guide nail area YK4, a plurality of game nails are continuously implanted at intervals of about 1.0 mm to form a game nail unit. A plurality of guides are provided so as to guide the ball flowing down the left side of the game area in front view to the center of the game area in front view. The spacing between the game nail units is such that at least one ball can pass through (that is, approximately 11.0 mm or more).

Here, when the game nail is bent due to a malicious act of a player, etc., it is necessary to hit the bent head of the game nail with a hammer or the like to return it to the normal planting angle. be. However, since the mini-head head 301 of the mini-head nail 300 is formed to have a smaller diameter than the normal head 201 of the normal nail 200, when the bent mini-head nail 300 is returned to the normal implantation angle, the normal nail 200 may be bent. The adjustment was more difficult, and it was difficult to obtain the desired implantation angle. In particular, the road nail planted in the fourth guide nail area YK4 guides the ball flowing down the right side of the game area when viewed from the front to the central side of the game area where the prize winning opening 64a and the like are arranged. If both ends of the road peg planted in the 4 guide peg area YK4 are improperly bent, the effect on the game results becomes greater.

Therefore, in the pachinko machine 10 of the second embodiment, normal nails 200 are planted at both ends of each game nail unit in the fourth guide nail area YK4, and other parts of the fourth guide nail area YK4 are planted with normal nails 200. A mini head nail 300 is implanted respectively. Since the head of the ordinary nail 200 (that is, the ordinary head 201) is formed to have a larger diameter than the mini-head head 301 of the mini-head nail 300, even if it is improperly bent, it cannot be adjusted. is easier than the mini-head nail 300. Therefore, the mini-head nails 300 are used in the fourth guide nail area YK4 except for both ends of the game nail unit, and the fourth guide nail is constructed so as to stabilize the rebound direction of the falling ball and make it difficult for the slump to occur. Both ends of the game nail unit in the area YK4 can be composed of ordinary nails 200 to facilitate correction even when cheating is committed.

In addition, the same configuration as that of the pachinko machine 10 of the first embodiment can produce the same effects as those obtained by the configuration.

<Third Embodiment>
Next, a pachinko machine 10 of a third embodiment to which the present invention is applied will be described with reference to FIG. In the pachinko machine 10 of the first embodiment, mini-head nails 300 are used as the game nails planted in the fourth guide nail area YK4, which are so-called road nails. On the other hand, in the pachinko machine 10 of the third embodiment, normal nails 200 and mini-head nails 300 are alternately planted in the fourth guide nail area YK4.

The pachinko machine 10 of the third embodiment will be described below, focusing on the differences from the pachinko machine 10 of the first embodiment or the second embodiment. In the following description of the pachinko machine 10 of the third embodiment, the same configuration and processing as those of the pachinko machine 10 of the first or second embodiment are designated by the same reference numerals as those of the first or second embodiment. and description thereof is omitted.

FIG. 11(a) is a front view of the game board 13 of the pachinko machine 10 of the third embodiment, and FIG. 11(b) is an enlarged front view of the fourth guide nail area of FIG. 11(a). In the pachinko machine 10 of the third embodiment, a plurality of game nail units are provided in the fourth guide nail area YK4, and both ends of each game nail unit are composed of ordinary nails 200, and the remaining portions are composed of mini-head nails. 300 and ordinary nails 200 are arranged alternately. With this configuration, more game nails can be planted in the fourth guide nail area YK4 than when the road nail is composed only of the ordinary nail 200, and less planting on the board surface of the game board 13 is possible. A large number of game nails can be planted even in a space, and the balls flowing down the game area can be dispersed.

In addition, the same configuration as that of the pachinko machine 10 of the first embodiment or the second embodiment can produce the same effects as those obtained by the configuration.

<Fourth Embodiment>
Next, a pachinko machine 10 of a fourth embodiment to which the present invention is applied will be described with reference to FIG. In the pachinko machine 10 of the third embodiment, normal nails 200 are attached to both ends of each game nail unit in the fourth guide nail area YK4. , and parts other than the both end portions were composed of mini-head nails 300. As shown in FIG. On the other hand, in the pachinko machine 10 of the fourth embodiment, the top of the third guide nail area YK3, which is continuously planted in the vertical direction of the game board 13 when viewed from the front, is composed of ordinary nails 200. The other parts are constructed with mini-head nails 300. - 特許庁

The pachinko machine 10 of the fourth embodiment will be described below, focusing on the points that differ from the pachinko machine 10 of the first to third embodiments. In the following description of the pachinko machine 10 of the fourth embodiment, the same configuration and processing as those of the pachinko machine 10 of the first to third embodiments are denoted by the same reference numerals as in the first to third embodiments. and description thereof is omitted.

FIG. 12(a) is a front view of the game board 13 of the pachinko machine 10 of the fourth embodiment, and FIG. 12(b) is an enlarged front view of the fourth guide nail area of FIG. 12(a). In the pachinko machine 10 of the fourth embodiment, in the third guide nail area YK3, a plurality of game nails are planted continuously at intervals of about 1.0 mm in an inverted V shape, and planted at the top. The game nails are composed of normal nails 200, and the game nails of parts other than the uppermost part are planted with mini-head nails 300. - 特許庁

This third guide nail area YK3 is planted in order to guide the ball flowing down from the upper part of the game area downward (for example, the upper part of the windmill 71). , the ball that has fallen vigorously from the vertical direction collides, and most of the balls that collide with the upper left side of the third pattern display device 81 when viewed from the front fall. There is a risk that the angle at which the nail is implanted will be deformed.

Therefore, in the pachinko machine 10 of the fourth embodiment, the normal nails 200 are planted in the uppermost part of the third guide nail area YK3, and the mini-head nails 300 are planted in the parts other than the uppermost part of the third guide nail area YK3. plant each. As described above, the normal nail 200 has a larger diameter than the mini-head head 301 of the mini-head nail 300 (that is, the normal head 201). However, the adjustment is easier than the mini-head nail 300. Therefore, the uppermost part of the third guide nail area YK3, which is most likely to receive the impact of the ball and is easily deformed, is composed of the easily adjustable normal nail 200, and the parts other than the uppermost part are composed of the mini-head nail 300 to flow down. It is possible to stabilize the rebound direction of the ball so that the gauge structure is less likely to cause a slump, and at the same time, the deformation caused by the impact of the ball can be easily corrected.

In addition, the same configuration as that of the pachinko machine 10 of the first to third embodiments can provide the same effects as those obtained by the configuration.

<Fifth Embodiment>
Next, a pachinko machine 10 of a fifth embodiment to which the present invention is applied will be described with reference to FIGS. 13 to 15. FIG. In the pachinko machine 10 of the first embodiment, the normal nail 200 is configured such that the axis (circle center) of the normal head 201 and the normal shaft 202 are aligned, and the entire circumference (outer circumference) of the normal shaft 202 The normal umbrella tip 201a2 of the normal head 201 is configured to protrude in the direction. In addition, the mini head nail 300 is configured such that the axis (circle center) of the mini head head 301 and the mini head shaft portion 302 coincide with each other, and the mini head shaft 302 extends in the direction of the entire circumference (outer circumference) of the mini head shaft portion 302 . The head 301 is configured so that the mini-head umbrella tip 301a2 protrudes. On the other hand, in the pachinko machine 10 of the fifth embodiment, an eccentric nail 400 whose head (ie, eccentric head 401) protrudes only from one of the body portions (ie, eccentric shaft 402) is used, The eccentric nail 400 is configured to be planted in the sixth guide nail area YK6 near the general winning opening 63. As shown in FIG.

The pachinko machine 10 of the fifth embodiment will be described below, focusing on the differences from the pachinko machines 10 of the first to fourth embodiments. In the following description of the pachinko machine 10 of the fifth embodiment, the same configuration and processing as those of the pachinko machine 10 of the first to fourth embodiments are denoted by the same reference numerals as in the first to fourth embodiments. and description thereof is omitted.

First, the configuration of the eccentric nail 400 of the fifth embodiment will be described with reference to FIG. 13 . FIG. 13(a) is a front view and a side view of an ordinary nail 200, and FIG. 13(b) is a front view and a side view of an eccentric nail 400 of the fifth embodiment. In addition, since the common nail 200 shown in FIG. 13A has the same configuration as that of the first embodiment and the like, the description thereof will be omitted.

As shown in FIG. 13(b), the eccentric nail 400 has a total length of about 33 mm, similar to the normal nail 200 and the mini-head nail 300. As shown in FIG. Further, the eccentric nail 400 is made of a brass material having a Vickers hardness of 150Hv to 230Hv or a metal having a similar hardness like the ordinary nail 200 and the mini head nail 300. It is constructed so as not to be easily broken (damaged) by the impact of the ball.

This eccentric nail 400 mainly comprises an eccentric head portion 401 , an eccentric shaft portion 402 , an eccentric small diameter portion 403 , an eccentric first parallel portion 404 , an eccentric screw portion 405 , an eccentric second parallel portion 406 and an eccentric sharp portion 407 . , and the portions 401 to 407 are continuously formed, and each portion 401 to 407 has a different diameter.

The eccentric head 401 is a portion on the free end side of the eccentric nail 400, and has a diameter φ5 of about 2.775 mm, similar to the mini-head head 301 (see FIG. 4(b)). It is configured to have a diameter 1.5 times the diameter φ6 of the portion 402 . The eccentric portion 401 is composed of an eccentric umbrella surface portion 401a formed in a spherical shape and an eccentric umbrella back portion 401b that can be positioned on the game board 13 side of the eccentric umbrella surface portion 401a. The eccentric bevel surface portion 401a has an eccentric bevel top portion 401a1 which is the center of the spherical shape, and an eccentric bevel tip portion 401a2 which is the outer peripheral portion of the eccentric bevel surface portion 401a and is continuous with the eccentric bevel back portion 401b. is formed. The eccentric umbrella tip portion 401a2 is chamfered in a predetermined manner (for example, an R shape with an R of 0.05 mm).

The eccentric head portion 401a1, which is the center of the circle of the eccentric head portion 401, is offset from the center of the circle of the eccentric shaft portion 402, which will be described later, toward the upper side (upper side in FIG. 13B). formed by That is, when the eccentric nail 400 is implanted in the game board 13, the eccentric umbrella tip part 401a2 of the eccentric head part 401 is positioned (projected) on the upper side of the game board 13 when viewed from the front, and is positioned (projected) on the lower side when viewed from the front of the game board. is configured so that the eccentric head 401 does not protrude. Therefore, when the eccentric nail 400 is implanted in the game board 13, the part of the eccentric shaft portion 402 projecting downward from the game board 13 in front view can be eliminated.

The eccentric head 401 is configured such that the height and width D13 of the eccentric head 401 is about 0.5 mm, which is half that of the normal head 201 . That is, the difference D16 between the height width D13 of the eccentric head portion 401 and the height width D1 of the normal head portion 201 is configured to be approximately 0.5 mm.

In addition, since the diameter φ6 of the eccentric shaft portion 402, which will be described later, is configured to be about 1.85 mm, the eccentric umbrella of the eccentric head portion 401 from the upper outer peripheral portion of the eccentric shaft portion 402 (that is, the upper side of the game board 13 when viewed from the front). A distance D14 to the tip portion 401a2 is configured to be approximately 0.926 mm. The amount D15 of protrusion of the eccentric head portion 401 in the left-right direction with respect to the eccentric shaft portion 402 is configured to be approximately 0.463 mm. In other words, the eccentric head portion 401 protrudes from the eccentric shaft portion 402 by a distance D14 (that is, about 0.926 mm) in the outer peripheral direction of the upper side of the game board 13 when viewed from the front, and is also projected by a distance D15 from the eccentric shaft portion 402 ( That is, it protrudes by 0.463 mm) in the outer peripheral direction of the game board 13 in the left-right direction when viewed from the front. That is, the difference between the projection amount D2 of the normal head portion 201 from the normal shaft portion 202 and the upward projection amount D14 of the eccentric head portion 401 from the eccentric shaft portion 402 is approximately 0.299 mm. A difference D17 between a projection amount D2 of the normal head portion 201 from the shaft portion 202 and a projection amount D15 of the eccentric head portion 401 from the eccentric shaft portion 402 to the left and right sides is approximately 0.762 mm. Therefore, the eccentric nail 400 has a smaller amount of protrusion from the shaft portion 402 than the ordinary nail 200 (the amount of protrusion of the eccentric nail 400 = 0.463 mm to 0.926 mm <the amount of protrusion of the ordinary nail 200 = 1.225 mm). is configured as

By making the diameter of the eccentric head portion 401 of the eccentric nail 400 smaller than the diameter of the normal head portion 201 of the normal nail 200 in this way, the eccentricity of the normal nail 200 is greater than that of the normal nail 200 when viewed from the front of the game board 13 . When the nail 400 is planted, the area of the board surface of the game board 13 that can be visually recognized increases. Therefore, in the area where the eccentric nail 400 is implanted, the board surface of the game board 13 can be easily visually recognized, and when the board surface of the game board 13 is designed, the design can be easily visually recognized by the player to enhance decorativeness. can be made better. In addition, when a role object or a display device is arranged on the rear surface of the game board 13 made of transparent resin in the area where the eccentric nail 400 is planted, the role object or the display device can be easily recognized visually. The movable mode of the object and the display contents on the display device can be accurately transmitted to the player, and the powerful presentation by the entire game board 13 can be easily seen, and the interest in the game can be enhanced.

The eccentric shaft portion 402 has a diameter of about 1.85 mm, similar to the normal shaft portion 202 of the normal nail 200, while its length (that is, from the connection portion with the eccentric head portion 401 to the eccentric small diameter portion 403) is approximately 1.85 mm. ) is about 18.0 mm, which is longer than the shaft portion 202 by about 0.5 mm.

The eccentric shaft portion 402 has an eccentric taper portion 402 a formed at a portion that is continuous with the eccentric head portion 401 . This eccentric tapered portion 402a has a predetermined taper shape (a so-called tapered shape) from the eccentric umbrella back portion 401b to the eccentric shaft portion 402, similar to the normal tapered portion 202a. The diameter is 1.85 mm on the shaft portion 402 side, the taper length is 0.3 mm, and the diameter tapers gradually at a taper angle of about 33.7 degrees.

The eccentric shaft portion 402 is a portion that protrudes (exposes) from the board surface side of the game board 13 when the eccentric nail 400 is implanted in the nail hole 13a (see FIG. 5) formed in the game board 13. It is configured to collide with balls flowing down the game area.

Here, since the height and width D13 of the eccentric head portion 401 (see FIG. 13(b)) of the eccentric nail 400 is formed to be approximately 0.5 mm, when the eccentric nail 400 is implanted in the game board 13, , the distance from the glass unit 16 (see FIG. 5) to the position where the eccentric bevel rear portion 401b and the eccentric bevel tip portion 401a2 (both are see FIG. 13(b)) of the eccentric head 401 are the same as those of the mini head nail 300. , D9+D13=about 1.9 mm (see FIG. 5). Then, at the position of D9+D13 from the glass unit 16, the vertical distance D11 from the tangent line of the point T2 to the point T4 where the perpendicular line from the tangent line of the point T2 intersects the sphere T is given by the formula {5. 5×5.5=3.6×3.6+(5.5−D11)×(5.5−D11)}, and D11=approximately 1.342 mm.

Therefore, in the eccentric nail 400, the amount of upward protrusion of the eccentric head 401 from the outer circumference of the eccentric shaft portion 402 is approximately 0.926 mm. short. That is, since the eccentric bevel tip 401a2 of the eccentric head 401 does not protrude beyond the vertical distance D11, when the ball Tc collides with the glass unit 16, it collides with the eccentric shaft 402 and the eccentric head 401 The ball can contact the glass unit 16 and the eccentric shaft portion 402 at the same time without colliding with the eccentric umbrella tip portion 401a2.

Specifically, the sphere Tc that collides with the glass unit 16 at the point Tc1 can contact the eccentric shaft portion 402 at the point Tc2 while contacting the glass unit 16 at the point Tc1. It cannot come into contact with the umbrella tip 401a2 (see FIG. 5).

Therefore, even if the ball flowing down the game area rebounds not to the board surface side of the game board 13 but to the glass unit 16 side at the place where the eccentric nail 400 is implanted, the eccentric head of the eccentric nail 400 It does not come into contact with the portion 401 and only collides with the eccentric shaft portion 402 with respect to the eccentric nail 400 . By constructing in this way, the ball colliding with the eccentric nail 400 can be easily rebounded to the board surface side of the game board 13 like the mini-head nail 300, and the rebounding direction can be easily predicted. Therefore, in the planting area of the eccentric nail 400 (that is, the sixth guide nail area YK6 (see FIG. 14)), it is possible to make it difficult for the slump to occur and to stabilize the flowing direction of the ball. It is possible to easily stabilize the winning rate of the game to a desired one. As a result, it is possible to realize a gauge configuration of the game board 13 in which slump is unlikely to occur, and it becomes easy to set the game performance when designing the board surface of the pachinko machine 10. - 特許庁In addition, even in the type test by a third-party organization, it is possible to stably win prizes in the general prize winning opening 63 and to make it difficult to fail the type test. Furthermore, by stabilizing the behavior of the ball flowing down the game area, it is possible to suppress the situation in which the ball does not enter the general prize winning opening 63 for a long period of time, thereby preventing the player from being dissatisfied.

In addition, by using the eccentric nail 400, it is possible to plant more game nails than when the normal nail 200 is planted even in a small planting space, thereby dispersing the balls flowing down the game area. can be done.

Furthermore, by hitting the eccentric head 401 with a hammer or the like by a person involved in the hall, the standing state of the deformed eccentric nail 400 can be corrected.

Incidentally, the eccentric small diameter portion 403, the eccentric first parallel portion 404, the eccentric screw portion 405, the eccentric second parallel portion 406, and the eccentric sharp portion 407 of the eccentric nail 400, which are the portions on the fixed end side of the eccentric nail 400, are the same as those of the ordinary nail. 200 and mini head nail 300, each small diameter portion 203, 303, each first parallel portion 204, 304, each screw portion 205, 305, each second parallel portion 206, 306 and each sharp point portion 207, 307. ing. With this configuration, the nail holes 13a (see FIG. 5) of the game board 13 can be formed in the same shape. Therefore, even when a plurality of types of nails 200, 300, 400 are used, the process for forming the nail holes 13a in the game board 13 can be simplified, and the manufacturing cost of the game board 13 can be reduced. .

Next, the case where the eccentric nail 400 is implanted in the game board 13 will be described with reference to FIGS. 14 and 15. FIG. FIG. 14 is a front view of the game board 13 of the pachinko machine 10 of the fifth embodiment. 15 is a schematic side cross-sectional view taken along line XV-XV of FIG. 14. FIG.

As shown in FIG. 14, in the sixth guide nail area YK6, which influences the winning of the general prize-winning opening 63, two eccentric nails 400 are placed just above the general prize-winning opening 63 in a front view at a distance that allows the balls to pass therethrough. planted respectively. As shown in FIG. 15, when the eccentric nail 400 is implanted in the nail hole 13a of the game board 13, the protrusion amount D14 of the eccentric head 401 to the upper side of the game board 13 is 0.926 mm. be. Therefore, when the ball T contacts the glass unit 16 and the eccentric shaft portion 402 at the same time, the position of the eccentric bevel tip portion 401a2 is within the range of the distance D11 (1.342 mm, see FIG. 5), so the eccentric head Part 401 cannot contact sphere T.

Also, as shown in FIG. 15, when the eccentric nail 400 is implanted into the nail hole 13a of the game board 13, the eccentric head part 401 does not protrude downward from the eccentric shaft part 402 of the game board 13. It has become. That is, there is no part protruding from the eccentric shaft portion 402 of the eccentric nail 400 in the direction perpendicular to the board surface of the game board 13 (the front direction of the pachinko machine 10, left side in FIG. 15) of the general flange portion 63a of the general winning opening 63. . In addition, the trunk portion of the general winning opening 63 (the portion on the right side of the general flange portion 63 a in FIG. 15) inserted into the router hole is formed longer than the length of the eccentric shaft portion 402 of the eccentric nail 400 .

Therefore, when the general winning opening 63 is attached to the game board 13 during manufacturing of the pachinko machine 10 or maintenance work, etc., the general winning opening 63 is not opened while the general winning opening 63 is guided along the router hole. The eccentric head 401 does not protrude (does not exist) in the direction perpendicular to the board surface of the flange portion 63a. Therefore, when the general winning opening 63 is attached to the game board 13, the general winning opening 63 (general flange portion 63a) is configured to be difficult to collide with the eccentric head 401. The portion 63a) or the eccentric nail 400 itself can be prevented from being damaged, and the installation work of the general winning opening 63 can be made more efficient.

In addition, the same configuration as that of the pachinko machine 10 of the first to fourth embodiments can produce the same effects as those obtained by the configuration.

<Sixth embodiment>
Next, a pachinko machine 10 of a sixth embodiment to which the present invention is applied will be described with reference to FIGS. 16 and 17. FIG. In the pachinko machine 10 of the first embodiment, mini-head nails 300 are used as the game nails planted in the fourth guide nail area YK4, which are so-called road nails. On the other hand, in the pachinko machine 10 of the sixth embodiment, the so-called life nails planted in the fifth guide nail area YK5 are also constituted by mini-head nails 300, respectively. Then, the mini head shaft portion 302 of the mini head nail 300 is arranged in the direction perpendicular to the game board 13 board surface of the winning flange portion 64d of the winning opening unit 64 and in the direction perpendicular to the game board 13 board surface of the display flange portion 80a of the variable display device unit 80. The mini-head canopy tip 301a2 of the mini-head head 301 protruding from is not positioned (not protruding).

The pachinko machine 10 of the sixth embodiment will be described below, focusing on the points that differ from the pachinko machine 10 of the first to fifth embodiments. In the following description of the pachinko machine 10 of the fifth embodiment, the same configuration and processing as those of the pachinko machine 10 of the first to fifth embodiments are denoted by the same reference numerals as in the first to fifth embodiments. and description thereof is omitted.

FIG. 16 is a front view of the game board 13 of the pachinko machine 10 of the sixth embodiment. 17 is a schematic side cross-sectional view taken along line XVII-XVII of FIG. 16. FIG.

As shown in FIG. 16, in the fifth guide nail area YK5, which influences the winning of the first starting hole 64a of the winning hole unit 64, there is a space that allows a ball to pass directly above the first starting hole 64a when viewed from the front. , two mini-head nails 300 are implanted at a predetermined angle (that is, θ1). As shown in FIG. 17, when the mini head nail 300 is implanted into the nail hole 13a of the game board 13, the mini head head 301 protrudes from the mini head shaft 302 by a distance of D4 in both vertical directions. (that is, 0.463 mm).

Conventionally, the prize-winning unit 64 and the variable display device unit 80 attached to the game board 13 have been plated or the like for the purpose of improving their decorativeness, and have been equipped with a large number of electronic components, which are relatively expensive. Positioned as a part. Therefore, when the game board 13 of the pachinko machine 10 is manufactured, after the winning opening unit 64 and the variable display device unit 80 (hereinafter referred to as "attachment parts") are attached before driving the game nails, the game nails are driven. In this case, if a game nail is driven into the mounting part due to some abnormality (for example, misalignment during transportation of the game board 13, etc.), the entire mounting part must be replaced, resulting in a large loss due to manufacturing error. Therefore, in the recent manufacturing process of the pachinko machine 10, the game nails are driven before the attachment parts are attached to the game board 13, and after driving the game nails, expensive parts such as the attachment parts are attached. manufactured.

In addition, due to the recent increase in the size of the variable display device unit 80 and the complication of the winning opening unit 64, etc., the size of the installation area of each attachment part is required. Therefore, the width of the board surface of the game board 13 formed between the variable display unit 80 and the prize winning unit 64 (that is, the distance between the router hole for mounting the variable display unit 80 and the router hole for mounting the prize winning unit 64 The portion formed at the tip of the guide nail) becomes smaller (thinner), and the implantation area of the dead nail planted in that portion (that is, the fifth guide nail area YK5) becomes narrower. Here, if the nail hole 13a for implanting the life nail is formed near the router hole, the game board 13 is likely to be cracked or cracked. It is necessary to form them at positions spaced apart to some extent. Therefore, the area where the dead nail is implanted (that is, the fifth guide nail area YK5) has a reduced degree of freedom in design due to the restriction of the nail hole 13a with respect to the flange portion of each component and the router hole.

Here, after driving a game nail into the game board 13, when attaching a mounting part to each router hole formed in the game board 13, the direction perpendicular to the board surface of the game board 13 at the hole edge of the router hole (pachinko machine 10 (left side of the drawing in FIG. 17)), the head of the game nail collides with the attachment part, Or there is a possibility that attachment parts may be damaged. In particular, the so-called life nail that is driven between the variable display device unit 80 and the prize winning unit 64 is an important nail that affects the game results. It may change significantly. In addition, the attachment parts must be carefully attached to the router holes in order to avoid collision with the game nails, which may reduce the manufacturing efficiency or yield of the game board 13 .

Therefore, the mini-head head portion 301 of the mini-head nail 300 (the tip of the mini-head umbrella) is positioned perpendicular to the board surface of the game board 13 of the winning flange portion 64d of the winning opening unit 64 (the front direction of the pachinko machine 10; the left side of the drawing in FIG. 301a2) does not exist. In addition, the display flange portion 80a of the variable display unit 80 is arranged in the direction perpendicular to the game board 13 (the front direction of the pachinko machine 10; the left side of the drawing in FIG. 17). It is configured so that the tip portion 301a2) does not exist.

Therefore, when the winning slot unit 64 or the variable display device unit 80 is removed from the game board 13 during manufacturing of the pachinko machine 10 or maintenance work, etc., the winning slot unit 64 or the variable display device unit 80 is guided along the router hole. Meanwhile, the mini-head head 301 is not positioned (overlapping) in the direction perpendicular to the board surface of each of the flanges 64d and 80a of the winning opening unit 64 or the variable display unit 80. Therefore, by configuring the winning opening unit 64 or the variable display device unit 80 (winning flange portion 64d or the display flange portion 80a) to be less likely to collide with the mini-head head portion 301, the winning opening unit 64 or the variable display device unit 80 (winning The yield can be increased by preventing the flange portion 64d or the display flange portion 80a) or the mini head nail 300 from being damaged. It is possible to improve the efficiency of the mounting operation of the display flange portion 80a).

Also, in other words, the winning opening unit 64 and the variable display device unit 80 can be brought closer to the site where the mini-head nail 300 is planted than when the normal nail 200 is planted. Therefore, when the mini-head nail 300 is adopted, the nail implantation area can be reduced as compared with the case where the ordinary nail 200 is adopted, and the degree of freedom in board surface design can be improved. In particular, the distance from the warp port (not shown) provided on the stage (not shown) formed at the lower end of the variable display unit 80 in front view and on which the ball can roll to the life nail (mini head nail 300) The distance can be made shorter than before. For example, by configuring the distance from the exit of the warp port to the site where the mini-head nail 300 is implanted to be less than the diameter of the ball, the ball ejected from the warp port is life. It is possible to prevent a situation in which the ball is repelled by another ball before it reaches the nail and does not enter the first starting hole 64a.

Furthermore, by implanting the mini-head nail 300 as a life nail in the fifth guide nail area YK5, the distance between the nails between the mini-head heads 301 can be set by the normal nail 200 as a life nail in the fifth guide nail area YK5. can be made larger than the distance between the nails between the normal heads 201 when implanted. That is, when the mini-head nail 300 is used as the life nail, it seems that the ball is more likely to enter the first starting hole 64a than when the ordinary nail 200 is used. Therefore, the player prefers playing with the pachinko machine 10 in which the life nail is planted with the mini head nail 300 rather than other machines in which the life nail is planted with the normal nail 200. It is possible to promote the operation of the pachinko machine 10 that employs

The present invention may be applied to a different type of pachinko machine or the like from the above embodiment. For example, once a jackpot is won, a pachinko machine (commonly known as a double-right product, a triple-right product, etc.) that increases the expected value of the jackpot until multiple (for example, 2 or 3) jackpot conditions occur, including that. may be implemented as Further, it may be implemented as a pachinko machine that generates a special game in which a predetermined game value is given to the player under the condition that the ball enters a predetermined area after the big winning pattern is displayed. Also, a pachinko machine having a prize winning device having a special area such as a V-zone and entering a special game state as a necessary condition for winning a ball in the special area may be implemented. Furthermore, in addition to pachinko machines, various game machines such as arepachi, majang ball, slot machines, and so-called game machines in which a pachinko machine and a slot machine are combined may be implemented.

In the slot machine, for example, the pattern is changed by operating the control lever in a state where the pattern effective line is determined by inserting a coin, and the pattern is stopped and fixed by operating the stop button. It is. Therefore, the basic concept of a slot machine is "provided with a display device that confirms and displays identification information after variably displaying an identification information string consisting of a plurality of pieces of identification information, The variable display of the identification information is started, and the variable display of the identification information is stopped due to the operation of the operation means for stopping (for example, a stop button) or after a predetermined period of time has passed, and the stop is displayed. It is a slot machine that generates a special game that gives a player a predetermined game value under the condition that the combination of time identification information is a specific one. In this case, the game medium is represented by coins, medals, etc. Examples include:

In a slot machine, the ratio of the number of game media paid out as a bonus (accessory) to the total number of game media (coins, medals) paid out during a predetermined period is the role ratio. Therefore, the number of game media to be paid out when each winning combination is established is stored in the ROM of the main controller instead of the prize ball number table 202e, and the same as the role ratio management chip or the prize ratio management chip is stored. In the control device that executes the function, the number of wins (symbols aligned on the activated line) during the non-bonus game period (normal period), the number of wins during the bonus game period, and the win during the AT period. By counting the number of wins won, the role ratio and the consecutive role ratio may be managed.

Further, as a specific example of a game machine that combines a pachinko machine and a slot machine, it is equipped with a display device for displaying a symbol sequence consisting of a plurality of symbols in a variable manner and then confirming and displaying the symbols, and is equipped with a ball launching handle. There are things that are not. In this case, after throwing a predetermined amount of balls based on a predetermined operation (button operation), for example, the pattern starts to change due to the operation of the control lever, for example, due to the operation of the stop button, or a predetermined As time elapses, the fluctuation of the symbols is stopped, and a special game is generated in which a predetermined game value is given to the player under the condition that the determined symbols at the time of the stop are so-called jackpot symbols, and the player is given a special game. A lot of balls are paid out to the tray at the bottom. If such a game machine is used instead of a slot machine, only the balls can be treated as game value in the game hall. It is possible to solve the problems such as the burden on the equipment due to the separate handling of the medals and the balls and the restrictions on the installation location of the game machine.

In the following, concepts of various inventions included in the above-described embodiments in addition to the gaming machine of the present invention are shown. It should be noted that each of the various inventive concepts shown below may add a part or a plurality of parts of the configuration of another inventive concept to the inventive concept, or add a part or a plurality of the configurations of the other inventive concept. The concept of the invention may be modified and configured by exchanging parts or the like.

By configuring in this way, the game result is changed to improve the interest of the game (for example, Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2018-145387)).

However, in the above game machine, it is necessary to make the structure of the game members suitable, and there is still room for improvement in this respect.

The inventions of group A have been made in view of the circumstances exemplified above, and their object is to provide a game machine having a game member with a suitable structure.

The nail head is
A gaming machine A0 characterized in that the gaming machine A0 is formed in a size that does not come into contact with a gaming ball flowing down the gaming area when the gaming nail is implanted in the gaming member.

According to the game machine A0, the base frame has a game member implanted with a game nail, the front part has a transparent member that allows the front side of the game member to be visually recognized, and the base part and the front part are When closed, a game ball can flow down a game area formed by the game member and the transparent member.

In the area, a plurality of them are planted at intervals that do not allow game balls to pass through. Thus, by planting the second nail in a predetermined area capable of guiding the game ball to the ball entering means, it is possible to plant more second nails than in the case of planting the first nail. In other words, when the same number of game nails are to be planted in a predetermined area, by adopting the second nail, it is possible to plant a plurality of the second nails in a small space. Therefore, by planting a large number of second nails in the predetermined area, it is possible to stabilize the flow of the game ball more easily, and at the same time, it is possible to save space in the area where the game nails are planted, and the board surface of the game board. There is an effect that the degree of freedom in designing can be improved.

Then, when the obstacle member is attached to the game member, the obstacle member tip provided on the obstacle member is positioned on the free end side, and the obstacle member trunk provided on the obstacle member is positioned closer to the obstacle member tip than the obstacle member tip. Located on the fixed end side, a game ball flowing down the game area can come into contact with the obstacle member body. In addition, an obstacle member is implanted between the first member and the second member when viewed from the front of the game member. Here, the tip of the obstacle member is formed so as not to be located in the direction perpendicular to the surface of the game member of the first member and the second member. As a result, since there is no hindrance member tip portion in the direction perpendicular to the game member surface of the first member and the second member, when either the first member or the second member is attached to the game member, Also, collision between the first member or the second member and the distal end portion of the obstacle member can be made difficult. Therefore, when attaching the first member or the second member to the game member, it is possible to prevent the first member, the second member, or the leading end portion of the obstructing member from being damaged. can facilitate attachment of the first member or the second member to the .

The game ball flowing down the game area is
A game machine E0 characterized in that it does not come into contact with said first obstacle member free end of said first obstacle member, but can come into contact with said first obstacle member body.

According to the game machine E0, the base portion has a game member to which the first obstacle member is attached, the front portion has a transparent member that allows the front side of the game member to be visually recognized, and the base portion and the front portion is closed, the game ball can flow down the game area formed by the game member and the transparent member. Then, when the first obstacle member fixing portion provided in the first obstacle member is fixed to the game member and the first obstacle member fixing portion is attached to the game member, the first obstacle member fixing portion provided in the first obstacle member The free end of the first obstacle member is located on the free end side of the cantilever-shaped first obstacle member, and the first obstacle member trunk portion, which is also provided on the first obstacle member, is fixed from the free end of the first obstacle member. located on the edge. Here, it is configured so that a game ball flowing down the game area does not come into contact with the first obstacle member free end of the first obstacle member, but can come into contact with the first obstacle member barrel. That is, in the cantilever beam-shaped first obstacle member, the first obstacle member free end portion, which is the farthest free end side from the game member, does not collide with the game ball, and the fixed end is moved from the first obstacle member free end portion. The first obstacle member body located on the side (that is, the game board side) and the game ball can collide with each other, so that the first obstacle member fixed portion, which is the fixed end of the first obstacle member, is fixed. The end moment can be made smaller than the fixed end moment when the game ball collides with the free end of the first obstacle member.

Then, when the first obstacle member is fixed to the game member, at least a portion of the first obstacle member fragile portion is configured to be positioned within the insertion hole. That is, when the first obstacle member breaks (shears) due to the stress caused by the collision of the game ball against the first obstacle member, the first obstacle member fragile portion formed more fragile than the first obstacle member body , and the fractured surface (broken portion) is easily formed inside the insertion hole of the game member. In other words, when the first obstacle member breaks, the parts such as the first obstacle member trunk are configured to be difficult to break, and the broken surface is unlikely to be formed in a state of protruding to the front surface side of the game member. is configured to As a result, when the first obstruction member is broken, the remaining portion of the first obstruction member (that is, the remaining portion of the first obstruction member fixing portion) that continues to be fixed to the game member is removed from the front surface of the game member by the dedicated jig. When pushing out from the back side from the side, the tip of the dedicated jig is inserted into the insertion hole of the game member, and the remaining portion of the broken first obstacle member is placed in contact with the broken surface. It can be pushed out to the side. Therefore, when the remaining portion of the broken first obstacle member is pushed out from the front side of the game member to the back side by the special jig, the edge of the insertion hole pushes the tip of the special jig to the side of the remaining portion of the first obstacle member. The remaining portion can be easily pushed out without being displaced from the fracture surface of the first obstacle member, and the remaining portion of the fractured first obstacle member can be easily pulled out from the back side of the game member. In addition, when the remaining portion of the broken first obstacle member protrudes from the plate surface of the game member, the tip of the dedicated jig is displaced from the fracture surface of the remaining portion and comes into contact with the surface of the game member. Although the surface may be damaged, by facilitating the formation of the fracture surface of the remaining portion inside the insertion hole, damage to the surface of the game member due to the tip of the special jig can be suppressed.
