Description

  The present invention relates to a guide rail used in a ball-type game machine represented by a pachinko machine.

  In a ball-type game machine such as a pachinko machine, a game ball (hereinafter also simply referred to as a ball) is launched obliquely upward by a predetermined launch mechanism, and this is run on a metal rail called a guide rail. Leading to the area. The game area is formed in front of a board called a game board, and a guide rail is usually provided on the game board. The ball is fired from a frame board installed below the game board.

  This is shown in FIG. This figure is an explanatory view showing a game board 70 and a frame board 72 built in the pachinko machine. It should be noted that, in reality, corner decorations and nameplates for electrical decoration are attached to the game board 70, but these are removed in this figure.

  As shown in the figure, a game area 70a provided with a liquid crystal display device 74, a winning opening 76, a variable winning device 78, a windmill 80, and the like is formed in a substantially circular shape on the gaming board 70. A belt-shaped guide rail 84 is erected from the lower side of the game area 70a clockwise to the position on the upper right side of the game area 70a. The guide rail 86 is provided on the inner peripheral side from the left end of the variable winning device 78 so as to be substantially parallel to the guide rail 84 and prevents the ball reaching the game area 70a from returning to the guide rail 84 again. is there.

  The frame board 72 is provided with a firing rail 90 for launching a pachinko ball (hereinafter simply referred to as a ball) 88 against the guide rail 84. As shown in the figure, the firing rail 90 is installed to the left, and when the ball 88 is struck by a launching mechanism (not shown), the ball 88 is launched onto the guide rail 84.

The hit ball 88 is moved by the guide rail 84 as indicated by an arrow to reach the game area 70a.
The firing force can be adjusted by the twisting amount of a firing handle (not shown). The ball 88 that cannot reach the game area 70a due to insufficient firing force moves in a direction substantially opposite to the arrow, and falls downward from a gap 92 provided between the firing rail 90 and the guide rail 84.

  However, according to the prior art, the ball 88 launched from the firing rail 90 jumps over the gap 92 and reaches the guide rail 84. If it collides with the guide rail 84 at this time, an extra spin may be applied to the ball 88 or it may bounce. Such balls 88 do not have a constant trajectory, and a player cannot aim the balls 88 at a desired position in the game area 70a.

The present invention has been made in view of these problems, Yu technique machine according to claim 1, ballistic hardly disturbed, balls, stably reaches the position aimed the player, the guide rail and the launch rail It is intended to make it possible to easily adjust the relative positions of the two .

In addition, the gaming machine according to claim 1 can stabilize the behavior of the guide rail in the width direction so that the game ball can be launched with a more stable trajectory, and can run without causing the ball to meander even with a slight centrifugal force. The goal is to make it possible.
Still another object of the gaming machine according to the second aspect of the present invention is to allow the ball to travel while being in close contact with the guide rail so that the ball is launched in a stable track in the game area.

A gaming machine according to claim 1 of the present invention, which has been made to solve such a problem, includes a frame-like member disposed on the front surface of the gaming machine,
In a gaming machine provided with a gaming board disposed on a cage of the frame-shaped member,
A plate-like hole is formed between the frame-shaped member and the game board so as to face a game area formed in the game board from the front surface of the frame-shaped member, and is fixed to the frame-shaped member. A member,
A launch rail on which balls launched from the launcher slide,
The ball fired from the firing rail is guided while being swung to the upper part of the game area, and the rail body with the magnet arranged on one side is integrally formed so as to be seamless,
Fixing the firing rail and the rail body to the plate member;
The cross section perpendicular to the ball traveling direction of the firing rail and the rail body is substantially M-shaped, and of the two slopes forming the upper part of the M-shape, the width of the slope on the magnet side is the other. It is characterized by having a cross section larger than the width of the slope .

The present invention described in claim 2 is the game machine according to claim 1,
It is formed in a curve corresponding to the outer peripheral shape of the punched hole, includes a corner decoration fixed to the plate-like member, and the rail body is curved corresponding to the outer peripheral shape of the punched hole. Features.

Yu technique machine according to claim 1 is provided with a rail body which corresponds to the conventional guide rail, and a firing rails formed integrally so as not this rail body and joint.

In a ball-type game machine equipped with this guide rail, the ball launched along the launch rail reaches the rail body, but since the rail body and the launch rail are formed integrally, the ball has a trajectory. It runs on the rail body without being disturbed. Moreover, the firing rail and the rail body are fixed to the plate member.

The balls are then pressed against the rail body by centrifugal force .

Therefore, according to the gaming machine of the first aspect, since the fired ball travels on the guide rail having no gap, the trajectory is not easily disturbed, and the ball stably reaches the position aimed by the player. To do . Moreover, since the guide rail and the firing rail are fixed with respect to the plate-like member, the relative positions can be matched.

In the guide rail according to the first aspect , the cross section (perpendicular to the traveling direction) of the rail body is substantially M-shaped. When traveling on the rail body, the ball is brought into contact with a recess at the upper portion of the substantially M-shape by centrifugal force. Therefore, it runs along a substantially M-shaped depression and does not bounce in the width direction.

Therefore, according to the gaming machine of the first aspect , since the cross section of the rail body is M-shaped, the behavior in the width direction is also stabilized.

The gaming machine according to claim 2 is provided with a corner decoration which is formed in a curve corresponding to the outer peripheral shape of the punched hole and is fixed to the plate-like member. The rail body is curved corresponding to the outer peripheral shape of the punched hole.

  Since the ball fired with sufficient launching force travels while being in close contact with the slope by centrifugal force, it is launched in a stable orbit within the game area.

Embodiments of the present invention will be described below with reference to the drawings.
First, FIG. 1 is a front view of a pachinko machine 2 to which the present invention is applied. As shown in this figure, the pachinko machine 2 has a frame-like member called a front frame 4 arranged on the front surface, a launch handle 6 that receives a player's operation below it, and a launch handle 6 by operating the launch handle 6. There is provided a receiving tray 8 in which game balls (not shown) to be played are stored. A sash 10 is provided above the tray 8, and a game board 14 disposed at the back of the front frame 4 can be faced through two transparent glass plates stored in the sash 10.

  On the front surface of the game board 14, a substantially circular gaming area 14 a provided with winning holes such as a winning prize opening 16, sleeve winning openings 18 a, 18 b, 18 c, 18 d, and an accessory such as a liquid crystal display device 20 and a variable winning apparatus 22 Is formed. In addition to this, the game area 14a includes corner lightings 24a and 24b, start winning ports 26a, 26b and 26c for starting processing for changing the display image of the liquid crystal display device 20, windmills 28a and 28b, guide rails 30 and the like. Is arranged.

  The game area 14a is surrounded by resin plate-like members (hereinafter referred to as corner decorations) 32a, 32b, 32c, 32d, 32e called tank windows, side covers, etc., and the end faces toward these game areas are It becomes a barrier for the game balls and prevents the game balls from rolling out of the game area 14a.

  When the firing handle 6 is rotated clockwise, the game ball is fired with a strength corresponding to the rotational angle. The game ball is defined by a launch rail (described later) disposed behind the right hand of the tray 8 and travels along the path between the corner decorations 32a and 32b and the guide rail 30 as indicated by arrows P and Q. And guided to the game area 14a. The magnet rail 34 is located on the front side of the passage in the drawing, and exerts a force for moving the ball traveling in the passage in the front direction.

FIG. 2 shows how each part described above is configured in the back of the front frame 4.
FIG. 2 is an exploded perspective view of the pachinko machine 2 in a direction in which the front frame 4 and the game board 14 are separated from each other. As can be seen from this figure, a plate-like member called a base plate 36 is disposed between the front frame 4 and the game board 14, and a punch hole 38 is formed at the approximate center thereof. The hole 38 is for facing the game area 14 a from the front surface of the front frame 4. Further, corner decorations 32a to 32e, launch rails 40, and the like are fixed to the base plate 36, and the magnet rail 34 is fixed to the front of the corner decoration 32a. Further to the back of the game board 14, a mechanism board having a portion serving as a path for winning game balls and prize balls, a mechanism for discharging the prize balls, and the like are arranged, which is a main object of the present invention. Since there is no direct relationship in matching the relative positions of the guide rail and the firing rail, the description is omitted.

  Next, the base plate 36 and the magnet rail 34 will be described with reference to FIG. FIG. 3 is a perspective view showing a state in which the corner decorations 32a to 32e are removed from the base plate 36. FIG. The base plate 36 is a substantially flat plate, in addition to the previously described punch hole 38, a window 42a for flowing out the prize balls discharged from the mechanism board to the tray 8, and the light of the lamp provided on the game board 14 side. Lamp holes 42b and 42c having a substantially rectangular shape for transmitting to the four sides are provided. The portion 44 of the launch rail 40 on which the ball slides has a rail body 46 extending in the launch direction, and there is no seam between the two 40 and 46 (hereinafter, particularly, Unless stated otherwise, the rail body 46 includes the portion 44). The base plate 36 is further formed with a plurality of tap holes 48 for fixing the corner decorations 32a to 32e.

  In addition to the tap holes 48, the base plate 36 is provided with through holes for fixing the base plate 36 to the front frame 4. However, in order to avoid complicated illustrations, It is omitted in the figure.

  The corner ornament 32 a is a plate-like member having a substantially right triangle, and a portion corresponding to the hypotenuse of the right triangle is formed in a curve corresponding to the outer peripheral shape of the punched hole 38. The magnet rail 34 is fixed to the front frame 4 side of the corner decoration 32a. A substantially rectangular hole is formed corresponding to the window 42 a of the base plate 36.

When the corner decoration 32 a is attached to the base plate 36, the edge of the rail body 46 is exactly located on the outer periphery of the magnet rail 34. This is shown in FIG.
FIG. 4A shows a state in which the rail body 46 when the corner decoration 32a is attached to the base plate 36 is viewed from the gaming area 14a toward the outer periphery. A point R is where the ball to be fired is located, and the ball placed here is launched by a launching device (not shown) and travels in the direction of the arrow. That is, this figure shows the rail body 46 that is actually curved in the depth direction of this figure in a straight line. The magnet rail 34 is shown in cross-section and inside. FIG. 4B is a view of FIG. 4A viewed from below.

  As shown in FIG. 4 (a), the magnet rail 34 is arranged on the side of the rail body 46, and is magnetized by magnets 50a, 50b,..., 50f (hereinafter referred to as magnet 50) arranged inside. The force which moves 52 like ball 52 'is exhibited. That is, the magnet 50 corresponds to the biasing portion of the present invention. In FIG. 4A, the middle is broken and omitted, so that a larger number of magnets 50 are actually arranged. Each magnet 50 is arranged such that a gap 54 is provided between adjacent magnets 50 and the rail body 46 has different polarities in the width direction.

  The magnet is covered with a ferromagnetic material 56 having a substantially U-shaped cross section as shown in FIG. On the right side of the magnet 50 is a thin plate 58 projecting from the curved end face of the corner decoration 32a, and the magnet rail 34 is bonded thereto.

  On the other hand, as shown in FIG. 4 (b), the rail body 46 has a substantially M-shaped cross section, and the rail body 46 is curved when the ball 52 is driven at a sufficient speed. (Refer to FIG. 3) As a result, centrifugal force is applied to the ball 52 and the vehicle travels in contact with the slopes 60a and 60b forming the upper part of the M-shape. When this is viewed from within the game area 14a, it appears as if the ball 52 travels on the valley line 62 as shown in FIG.

  A notch 64 is formed in the wider slope 60 a, and the width is slightly larger than the diameter of the ball 52. The right side of the notch 64 is a portion 44 where the ball slides on the firing rail 40 shown in FIG. The entire width of the rail body 46 is slightly wider than twice the diameter of the ball 52 so that the ball traveling on the valley line 62 and the ball in contact with the thin plate 58 can pass through without touching. Yes.

  The ball 52 fired with a sufficient firing force from the point R of the rail body 46 is in close contact with the inclined surfaces 60a and 60b by centrifugal force while receiving the force in the left direction of the figure by the magnet 50. Continue driving. It is then fired in a stable orbit within the game area 14a.

  On the other hand, when the firing force is small, the speed of the ball 52 decreases, the magnetic force overcomes the centrifugal force, and the ball 52 collides with the thin plate 58. While the ball 52 is in contact with the thin plate 58, the ball 52 receives gravity and moves downward, and falls off the notch 64 in the back direction of the figure. When moving downward, the ball 52 is accelerated, but the magnetic force acting on the ball 52 once approached is strong, so that it reaches the notch 64 without leaving the thin plate 58. The entire width of the rail body 46 is wide enough to allow the ball 52 traveling on the valley line 62 and the ball 52 ′ in contact with the thin plate 58 to pass through without touching, so the return ball 52 ′ is fired next. The ball 52 is removed from the notch 64 without obstructing the running of the ball 52 (or already fired). That is, the notch 64 corresponds to the departure port of the present invention.

  Further, although the magnetic force of the magnet 50 is used as a force for moving the ball 52 having insufficient launching force in the direction of the inclined surface 60a, this does not prevent detection of fraud. In other words, a traditional fraudulent act against pachinko machines is to use a magnet to place a ball in a desired prize opening. In response to this, a magnetic field sensor or the like is installed in the pachinko machine to detect abnormal magnetism. Then, you may take measures such as sounding an alarm. Since the magnet 50 is housed in the U-shaped ferromagnet 56, the lines of magnetic force only slightly leak from the thin plate 58 and can only move the ball 52 in the direction of the inclined surface 60a. Accordingly, the influence on the magnetic field sensor is extremely small, and an illegal act using a magnet can be detected.

  Moreover, if the ball | bowl 52 is urged | biased using the magnet 50, it will be anxious about the ball | bowl 52 itself magnetizing. However, since the polarities of the magnets 50 are staggered, the magnetization of the balls 52 can be prevented.

  The magnet 50 can be applied with a biasing force as a magnet rail 34 in a wide range of the rail body 46. Therefore, the ball 52 that could not reach the game area 14a can be removed downward from the notch 64 without leakage.

  Further, since the rail body is M-shaped, the ball 52 can be run without meandering against the biasing force of the magnet 50 even with a slight centrifugal force. Moreover, since the M-shape is asymmetrical, the rail body 46 capable of passing the return ball 52 ′ and the firing ball 52 can be realized with a minimum width. This is extremely useful in the pachinko machine 2 where the installation width of the rail body 46 is limited.

As described above, the pachinko machine 2 has been described as an embodiment to which the present invention is applied. However, the present invention is not limited to such an embodiment and can be implemented in various modes.
For example, in addition to a pachinko machine, the present invention may be applied to a ball ball game machine such as an arrange ball pachinko machine or a sparrow ball game machine. Regardless of the application to any bullet-type game machine, it is possible to launch a game ball with a stable trajectory.

  Moreover, although the cross section of the rail main body 46 was an asymmetrical M-shape as shown in FIG.4 (b), other shapes may be sufficient. For example, the slope 60a may be folded in the middle in the width direction. In this case, the ball 52 ′ with insufficient firing force is attracted to the magnet 50 beyond the mountain ridge. In this way, the ball 52 ′ cannot return to the valley line 62 unless it exceeds the ridge again, so that it is not necessary to provide the magnet 50 in a wide range as shown in FIG.

  In the pachinko machine 2, the magnet rail 34 is provided on the thin plate 58 of the corner decoration 32a in order to position the magnet rail 34 at the edge of the rail body 46. However, the magnet rail 34 may be installed by other methods. For example, it is conceivable to provide a magnet rail 34 between two pieces of glass fitted to the sash 10. In this way, it is not necessary to secure a space for providing the magnet rail 34 between the glass and the corner decoration 32a.

It is explanatory drawing which shows the front surface of the pachinko machine 2 to which this invention is applied. 2 is an exploded perspective view of a pachinko machine 2. FIG.
