Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball-and-ball type game machine such as a pachinko machine, an arrange ball type pachinko machine, or the like.

[0002]

2. Description of the Related Art Conventionally, in a ball-type game machine such as a pachinko machine, a game ball launched from a launch rail is drawn in an arc along a guide rail and is thrown into a game area. The game area is a substantially circular area formed on the game board, and the guide rail is provided in a wall shape along the periphery of the game area so as to draw a semicircle from the lower end of the game area to the upper end. Has been. One of the launch rails is provided on a launch rail support frame (hereinafter, referred to as a launch rail support portion) arranged below the game board. Incidentally, a passage for prize balls, a passage for prize balls, and a part called a mechanism board having a mechanism for discharging prize balls are arranged further in the back of the game board.

In general, a pachinko machine can be made a new model by replacing only the game board.
That is, by changing only the game board while leaving the launch rail support portion and the mechanism board as it is, it is possible to update at a low cost to a new model having a different arrangement of nails and accessories.

[0004]

[Problems to be Solved by the Invention]
When replacing the model, it is difficult to align the guide rail and the launch rail. That is, in the pachinko machine, the launch rail support mechanism and the firing handle for firing the game balls are arranged on the front side of the pachinko machine called the front frame, and one guide rail is fixed to the game board and the pachinko machine together with the mechanism board. On the body side of. The front frame and the body side are usually joined by a hinge mechanism, and when the game board is replaced, the front side is detached from the body side by opening the door. In this state, the firing rail is attached to the front frame via the firing rail support portion, and thus is in a state of being separated from the guide rail. The guide rail is replaced with the game board, and a new guide rail is attached to the main body side together with the game board. For this reason, the relative position between the launch rail and the guide rail changes delicately each time it is replaced. If this relative position is improper, the game ball that is fired will behave irregularly before it reaches the game area, causing a loss of motivation to play. In the past, in order to make the relative position proper, the end of the guide rail (the portion near the firing rail) was appropriately bent and finely adjusted, but this work requires skill.

Further, in a conventional ball-type game machine, as a method of fixing the guide rail to the game board, the guide rail is sandwiched between the heads of the split pins and the split pins are driven into the game board. There is a fixing method. However, it is extremely difficult to replace the guide rail once fixed by this method. In addition, the guide rail fixed in such a special process is removed together with the game board as described above and a new guide rail is removed regardless of whether the guide rail itself needs to be replaced each time the model is replaced. It is extremely uneconomical to use.

The present invention has been made in view of the above problems, and an object thereof is to facilitate relative alignment between a launch rail and a guide rail.

[0007]

A ball-and-ball-type gaming machine according to claim 1, which has been made to achieve the above object, has a gaming board in which a game area is formed on a front surface of the bullet-ball type gaming machine. A guide rail that is arranged in a wall shape along the periphery of the game area from a substantially lower end position to a substantially upper end position of the game area, and the game ball is inserted into the guide rail from substantially below the game ball. A ball having a launch rail for supplying the launch area to the game area, a launch rail support portion arranged below the game board and supporting the launch rail, and a front frame arranged in front of the game board. In the gaming machine, a guide rail support portion that supports the guide rail at the above-mentioned arrangement position is provided above the launch rail support portion.

The invention described in claim 2 is the same as claim 1.
In the ball-and-ball-type gaming machine according to, the guide rail support portion is a plate-shaped member that is superposed on the front surface of the game board,
A mounting portion having a substantially circular hole facing the game area, and a substantially plate-like member having a thickness corresponding to the width of the guide rail, wherein a hole is formed on the front surface of the mounting portion. A plurality of corner ornaments are arranged so as to surround it, and a receiving groove is formed on the front surface of the placing portion along the periphery of the punched hole from a substantially lower end position to a substantially upper end position. A groove which can be aligned with the receiving groove at a substantially same position which is apart from the receiving groove by a distance substantially equal to the width of the guide rail when the corner ornament is arranged on the mounting portion. The guide rail is supported by sandwiching both edges of the guide rail with the receiving groove and the rail retainer.

According to a third aspect of the present invention, in the ball-ball type game machine according to the first or second aspect, the guide rail support portion and the launch rail support portion are fixed to the front frame. It is characterized by

[0010]

According to the first aspect of the invention, the guide rail support portion for supporting the guide rail is provided, and the guide rail support portion extends above the firing rail support portion. That is, the guide rail is not fixed to the game board, but is fixed to the guide rail support portion, which is an integral part of the member to which the firing rail is fixed.

Therefore, according to the first aspect of the present invention, the guide rail support portion is provided, and the guide rail support portion is formed integrally with the firing rail support portion. The relative position can be easily secured. Also, since the guide rail is not fixed to the game board, the guide rail is not replaced even when the game board is replaced for changing the model of the ball-type game machine, and the relative position with the launch rail is The secured guide rail can be used across multiple models, which is economical.

According to the second aspect of the present invention, the guide rail support portion is a mounting portion which is a plate-like member in which a substantially circular hole facing the game area is formed, and the hole is surrounded on the front surface thereof. It is composed of a plurality of corner decorations. The guide rail is supported by being sandwiched between a receiving groove formed around the punched hole of the mounting portion and a groove formed in the rail pressing portion provided in the corner decoration. The groove formed in the rail holding portion is formed so as to be able to be aligned with the receiving groove when the corner ornament is arranged on the mounting portion, and is separated from the receiving groove by a distance corresponding to the width of the guide rail. Therefore, the guide rail is supported along the punched hole so that it is erected substantially perpendicular to the mounting portion. Then, in this state, when the placing portion is overlapped with the front surface of the game board, the game area faces the hole of the placing portion, and the guide rail is arranged around the game area.

Therefore, according to the invention of claim 2, in addition to the effect of the invention of claim 1, the guide rail is
Since the guide rail is sandwiched between the receiving groove and the rail pressing portion, the guide rail can be supported in a stable state. Further, the guide rail can be easily replaced by the easy work of attaching and detaching the corner decoration to the mounting portion.

In the ball-ball type game machine according to the third aspect, the guide rail support portion and the launch rail support portion are fixed to the front frame. Therefore, even when the game board is exchanged for changing the model, the launch rail and the guide rail remain fixed to the front frame side, and the relative positions of both rails are less likely to change.

This will be described with reference to FIG. FIG. 6A shows a corner decoration 32b.
6B is a front plan view thereof, FIG. 6B is a bottom plan view thereof, FIG. 6C is a rear view thereof, and FIG. Since the rail pressing portions 54a and 54c formed on the corner decorations 32a and 32c have substantially the same shape as the rail pressing portion 54b, the rail pressing portion 54b will be representatively described.

The rail pressing portion 54b is formed so as to project from the edge of the end surface 50b on the front surface 66 side.
As shown in FIG. 6C, a groove 68 that can be aligned with the receiving groove 44 is formed on the back surface side along the end surface 50b. When shown in cross section, as shown in FIG. 6D, the rail pressing portion 54b is formed in a hook shape. Here, to supplement the shape of the corner decoration 32b, the corner decoration 32b is made hollow and lightweight as shown in FIGS. 6 (c) and 6 (d). 32
The same applies to a and 32c to 32e.

Next, the guide rail 56 will be described with reference to FIG. FIG. 7A is a front view of the guide rail 56,
FIG. 7B is a bottom plan view thereof. In this figure, in order to clarify the shape of the guide rail 56, only the thickness is shown to be increased. The guide rail 56 has a shape bent in an arc shape corresponding to the holding groove 44 of the base plate 36. One end 56a of the receiving groove 44 corresponding to the B portion side is bent to form a through hole 70 into which the boss portion having the tap hole 64 is inserted. Both edges 7 of this guide rail 56
2a and 72b, receiving groove 44 and rail pressing portions 54a-5
When sandwiched with 4c, one surface 74 of the guide rail 56 is brought into contact with the end surfaces 50a to 50c of the corner decorations 32a to 32c, and the guide rail 56 is firmly supported. In addition,
The portion of the base plate 36 where the corner decorations 32a to 32e are arranged corresponds to the mounting portion of the present invention, and the remaining portion of the base plate 36 corresponds to the firing rail support portion.

Next, the launch rail 40 will be described with reference to FIG. FIG. 8A is a front view of the launch rail 40,
FIG.8 (b) is the FF sectional drawing. Launch rail 40
The rail main body 48, a holding portion 76 for holding the game ball at one end of the rail main body 48, and a support portion 78 for supporting the rail main body 48 and the holding portion 76 are three members.

The rail main body 48 has a holding portion 7 in the longitudinal direction.
The end on the 6 side is bent into a substantially L shape, and the bent portion 48a cooperates with the holding portion 76 to support the game ball.
Further, the cross-sectional shape is M-shaped as shown in FIG. 8B, and the game ball is supported by the valley portion of the M-shape. Then, the screws 82 are inserted so as to sandwich the spacer 80 in the lower part of the M-shape, and are tightened into the corresponding tap holes 62, so that the spacers 80 are fixed to the base plate 36 together with the support portions 78.

The holding portion 76 is a plate member having a substantially trapezoidal shape, and is fixed near the bent portion 48a of the rail main body 48 at the support portion 78 to support the game ball in cooperation with the rail main body 48. The supporting portion 78 cuts the sheet metal into a shape as shown in this figure and causes the one end 84 thereof, and at the same time, a through hole for fixing the holding portion 76 and the rail main body 48 and the supporting portion 78 itself are formed on the base plate 36. A through hole for fixing is formed. The triggered end 84
Is for preventing game balls that have flowed backward and dropped from the gap 60 (see FIG. 4) from colliding with the end surface 48b of the rail body 48.

According to the pachinko machine 2 described above, since the launch rail 40 and the guide rail 56 are both fixed to the base plate 36 even though the gap 60 is provided, their relative positions are different. Specified, launch rail 4
The game ball launched from 0 can jump over the gap 60 and land on the guide rail 56 at an appropriate position. Further, even when the guide rail 56 is damaged due to aging or the like and the replacement is required, there is no need to adjust the position after the replacement for the same reason, and the relative position to the firing rail can be made appropriate. Also in this replacement work, since the guide rail 56 is not fixed to the game board by the split pin as in the conventional case, the front frame 4 is removed to expose the intermediate portion A and the corner ornament 32.
It can be easily replaced by removing a to 32c.

Moreover, since both rails 40 and 56 are fixed to the front frame 4 together with the base plate 36, even if the model of the pachinko machine 2 is exchanged, that is, the game board 14 is exchanged, the rails 40 and 56 are relatively opposed to each other. Position and guide rail 5
The shape of 6 is the same as before the replacement, and an appropriate positional relationship and shape can be maintained. In addition, when the model was replaced in the past, the guide rails fixed to the game board were also replaced as the game board was replaced, regardless of the degree of pain.
Since the guide rail 56 of the pachinko machine 2 is fixed to the front frame 4 side, it is not replaced and can be used over a plurality of models, which is economical.

Since the guide rail 56 is sandwiched between the receiving groove 44 and the rail pressing portions 54a to 54c, the guide rail 56 is firmly supported. Figure 9
This will be described with reference to FIG. FIG. 9A is a sectional view taken along line GG of FIG. It should be noted that 86 and 88 indicated by the two-dot chain line represent the glass plate and the game ball housed in the sash 10 (see FIG. 1 and FIG. 2), respectively, and the game board 14 is also indicated by the two-dot chain line. .

As shown in FIG. 9A, the guide rail 56
Are rail pressing parts 54a to 54 in the vertical direction in the figure, respectively.
It is supported by the groove 68 of c and the receiving groove 44, and the one surface 74 is supported by the end surfaces 50a to 50c of the corner decorations 32a to 32c. Therefore, the game ball 88 launched from the launch rail 40 (see FIGS. 4 and 8) collides with the guide rail 56 many times, and the guide rail 56 receives a centrifugal force from the running game ball 88. However, the guide rail 56 is not dented or the upper edge 72b in the drawing is not inclined to the left. Therefore, the travel route of the game ball is always stable, and the player of the pachinko machine 2 can play a desired game.

Although the pachinko machine 2 which is one embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned configuration and can be implemented in various modes. For example, in the pachinko machine 2, one side 74 is brought into contact with the end surfaces 50a to 50c of the corner decorations 32a to 32c to guide the guide rail 5
6, the base plate 36 may support one surface 74. This is shown in FIG.
It is (b) and shows the part equivalent to the GG sectional view of FIG. That is, one of the edges raised on both sides of the receiving groove 44 'is raised to form a wall, and the wall surface 90 supports one surface 74 of the guide rail 56. Correspondingly, the corner decoration 32 'has a lower end surface 50'. Even in this case, like the pachinko machine 2, the guide rail 56 can be firmly supported.

Further, in the pachinko machine 2, the launch rail 40 and the guide rail 56 are fixed to the base plate 36, and the guide rail 30 is still erected on the game board 14 as before, but the guide rail 30 is also kept on the base plate 36. You may fix it to.
To do this, for example, in FIG.
It is conceivable that the edge of the above is projected in the central direction from the vicinity of the B portion to the central portion between B and C, and the guide rail 30 is erected on this projected portion. By doing this, in addition to the launch rail 40 and the guide rail 56, the guide rail 30 is attached to the front frame 4 side, so that the liquid crystal display device 20 is provided on the game board 14 side.
Only prizes such as the variable winning device 22 and nails are left. When the guide rail 30 is attached to the game board 14, the guide rail 30 is sandwiched between the heads of the cotter pins, and the cotter pins are driven into the game board 14, in the same manner as a conventional guide rail. Has been. Therefore, special equipment was required when fixing the guide rail 30 to the game board 14, but by fixing the guide rail 30 to the base plate 36 as described above, the manufacturing process of the game board 14 can be simplified. You can

Further, unlike the guide rail 56, the guide rail 30 does not require mounting accuracy, so that the base plate 3
It may be molded integrally with the 6. If you want the guide rail 30 to have the same mounting strength as the guide rail 56,
Similarly to the base plate 36, the rail pressing portions 54a and 54b are also projected, and a groove for the guide rail 30 is newly formed in this portion and the base plate 36, and the guide rail 3 is formed by these grooves.
You may make it pinch 0. In this case, if the rail pressing portions 54a and 54b are made of a transparent material,
As before, it can be seen that the game balls are traveling in the passages between the corner decorations 32a and 32b and the guide rail 30 as shown by arrows P and Q (see FIG. 1).
