FIG. 7 is a plan view of the pachinko gaming machine of the present embodiment. However, in FIGS. 1 and 6, a winning opening, a symbol display device, a nail, and the like provided on the game board 21 are omitted.

(1) Structure and operation of the pachinko gaming machine of the present embodiment As shown in FIG. 6, this pachinko gaming machine includes an outer frame 1 and a game board mounting frame 2, and On the mounting frame 2, a game board 21, a glass door 22 that covers the game board 21, an upper tray 23, a lower tray 24, a firing lever 25, and the like are installed. As shown in FIGS. 1 and 7, the game board 21 is installed in the game board mounting frame 2 by a game board support mechanism 26 and a game board shifting mechanism 27, and the lower side is pivotally supported by the game board support mechanism 26. The upper part is supported by a game board shifting mechanism 27.

As shown in FIG. 1, the game board support mechanism 26 is a pair of joints provided at a lower portion of the game board 21 on the left and right sides. As shown in FIG. 2, the game board support mechanism 26 supports the game board 21 so as to be rotatable in the front-rear direction.
With the lower side supported by the game board support mechanism 26 as an axis, the upper part can be swung back and forth within the game board mounting frame 2. In the present embodiment, a direction toward the front side of the pachinko gaming machine is referred to as “front”, and a direction toward the back side of the pachinko gaming machine is referred to as “rear”.

As shown in FIG. 2, the game board shifting mechanism 27 includes a bearing 27a provided at the upper end of the game board 21, a fixed nut 27b provided below the upper portion of the game board mounting frame 2, and a fixed part 27b. An adjustment bolt 27c that penetrates through the nut 27b back and forth and is rotatably supported by the bearing 27a. The game board shifting mechanism 27 corresponds to “inclination angle adjusting means” described in the claims.

When the adjustment bolt 27c is rotated, it moves forward or backward with respect to the fixed nut 27b. Since the adjustment bolt 27c is rotatably supported by the bearing 27a, the bearing 27a and the upper part of the game board 21 on which the bearing 27a is installed move as the adjustment bolt 27c moves back and forth. Since the lower part of the game board 21 is rotatably supported by the game board mounting frame 2 by the above-described game board support mechanism 26, the game board 21 is rotated by the adjustment bolt 27c, so that the game board support mechanism is rotated. 26
Is pivoted forward or backward in the game board mounting frame 2 around the axis, and the inclination angle thereof is changed.

At this time, the inclination angle of the game board 21 is 0.9
An angle of about 45 degrees is particularly preferable, but the angle is such that the falling game ball does not largely separate from the game board 21 and can move smoothly, and the upper part of the game board 21 and the glass door 22
Is preferably within a range of 15 to 30 mm. The torque required for rotating the adjustment bolt 27c is provided so as to be equal to or more than a certain value. Therefore, the game board 2
After adjusting the inclination angle of 1, the adjustment bolt 27c does not loosen naturally during a game, for example. That is, the game board shifting mechanism 27 corresponds to the “tilt angle adjusting means” described in the claims, and also fulfills the function of the “tilt angle fixing means” in the claims.

In the above embodiment, the game board shifting mechanism 27 is provided in a pair of symmetrical positions on the left and right sides. However, it is not always necessary to provide two.
Only one may be used. Even in such an embodiment, the above function is sufficiently performed.

A stopper 28 is provided on the inside of the side of the game board mounting frame 2. This stopper 28
Is a wall-shaped structure provided so as to sandwich the game board 21 from the front and back, as shown in FIGS. 1 and 3 to 5, and the upper end of the game board 21 swings about 15 mm back and forth. It is the distance that can be done. The game board 21 cannot swing beyond the stopper 28 because the front and rear sides of the game board 21 are blocked by the stopper 28. The stopper 28 corresponds to the “tilt preventing angle limiting means” described in the claims.

(2) Effects of the Pachinko Game Machine of the Present Embodiment The pachinko game machine of the present embodiment can adjust the inclination angle of the game board 21 by rotating the adjustment bolt 27c. Therefore, the inclination angle of the game board 21 can be easily adjusted, and the winning probability of the game ball can be adjusted.
In the pachinko game machine of the present embodiment, the game board 2
When installed in a pachinko gaming machine, 1 is covered by a glass door 22 as shown in FIGS. The game board 21 is used by being tilted about 0.945 degrees mainly so that the upper part is on the rear side and the lower part is on the front side. For this reason, the interval between the game board 21 and the glass door 22 is
The upper part of the game board 21 is wider, and the lower part is narrower.

In the pachinko gaming machine of the present embodiment, the game board 2 is arranged such that the upper portion thereof is closer to the rear with the lower portion of the game board 21 as an axis, that is, the upper portion is away from the glass door 22.
One is to tilt. For this reason, it is necessary to drop the game ball at the lower part of the game board 21 (1 in this embodiment).
(5-30 mm) If a space is provided with the glass door 22,
Even if the inclination angle of the game board 21 is changed, the space between the game board 21 and the glass door 22 is maintained as long as it is necessary for the game balls to fall.

That is, for example, if the game board 21 is tilted by 0.945 degrees in the pachinko game machine of the present embodiment,
The lower side of the game board 21 comes out 6.75 mm before the upper side. This is equivalent to 1/2 of the diameter of the game ball. Therefore, if the lower side is set forward with the upper side as the axis, the interval with the glass door 22 is reduced depending on the inclination angle, and the fall of the pachinko ball is hindered. Since the pachinko gaming machine of the present embodiment has the above-described structure centered on the lower side, such a situation does not occur.

The swing width of the game board 21 before and after is often several mm at the upper end of the game board 21. Therefore, when the game board 21 itself is moved, fine adjustment of the inclination angle thereof is required. It will be very difficult. However, since the pachinko gaming machine of the present embodiment adjusts the position of the upper end of the game board 21 by the adjustment bolt 27c and the fixing nut 27b, by rotating the adjustment bolt 27c, the game board 21 can be easily rotated. Fine adjustment of the tilt angle can be performed. This is because the operation amount is expanded by the game board shifting mechanism 27.

Further, the game board shifting mechanism 27 includes a game board 21.
And an adjusting bolt 27
Since the adjustment knob of the head of c is on the back side of the game board 21,
Does not spoil the aesthetics. Since the adjustment knob on the head of the adjustment bolt 27c is located on the back side of the game board 21, such an adjustment device is provided on the side of the game board 21 such as the game board mounting frame 2 or the like. Does not interfere with the structure. In addition, the rotation of the adjustment bolt 27c requires a torque equal to or more than a certain value, and the adjustment bolt 27c does not loosen naturally. Therefore, the tilt angle of the game board 21 after the adjustment can be kept constant.

Further, since the pachinko gaming machine of this embodiment is provided with the stopper 28, even if the game board shifting mechanism 27 breaks down and the upper end of the game board 21 becomes free, the game board supporting mechanism 26 is used as an axis. The game board 21 does not fall down. Therefore, even if the upper end of the game board 21 is free, the game board 21 does not collide with the glass door 22 covering the front, and the game board 21 is safe.

(3) Embodiments of Other Embodiments The present invention is not limited to the specific embodiments described above, but may be modified in various ways within the scope of the present invention depending on the purpose and application. It can be. For example, if the torque required for the rotation of the adjustment bolt 27c is set low, a tightening nut is separately provided, and after the game board 21 is adjusted, the fixing nut 27b is tightened with the tightening nut. In the same manner as described above, the loosening of the adjustment bolt 27c can be prevented.

As another embodiment of the game board shifting mechanism, there is one as shown in FIGS. FIG. 8 shows a game board shifting mechanism using gears 31 and 32.
In this game board shifting mechanism, by providing a knob 39 or the like for angle adjustment on the side of the game board mounting frame 2, while visually observing the inclination angle of the game board 21 with respect to the game board mounting frame 2 from the side, Can be adjusted.

FIG. 9 shows the worm 33 and the worm gear 34.
FIG. According to this method, as in the case of the bolt and the nut, the amount of operation is greatly increased, so that a very fine adjustment of the inclination angle becomes possible. However, in the modes shown in FIGS. 8 and 9, it is necessary to separately provide a mechanism for fixing the inclination angle of the game board. For example, a fixing mechanism similar to FIG. 11 in which the rotation of the gear is locked by a claw, a method in which the shaft of the gear is fastened with a nut, and the like can be considered.

On the other hand, FIG. 10 shows a game board shifting mechanism using stop holes 35 and pins 36. FIG.
Shows a game board shifting mechanism using gears 37 and claws 38. According to these methods, a mechanism for fixing the inclination angle of the game board can be realized simultaneously with the game board shifting mechanism.

Further, in the above embodiment, the game board shifting mechanism 27 is provided in a pair of right and left at symmetrical positions. However, it is not always necessary to provide two game board shifting mechanisms. Only one location may be provided, or three or more locations may be provided. Furthermore,
The game board shifting mechanism may be provided in a horizontally long manner, for example, the gear teeth are provided horizontally on the entire upper side of the game board. If the game board support mechanism is provided at three or more places, the angle of the game board can be adjusted more stably, and in some cases, the warpage of the game board can be adjusted. If the game board shifting mechanism is provided on the entire upper side, the angle of the game board can be adjusted more stably. In addition, when the game board shift mechanism is provided only in one place on the upper side of the game board,
The position can be an appropriate position.

Another embodiment of the game board support mechanism is as shown in FIGS. FIG. 12 is an explanatory view showing a game board support mechanism by the concave portion 41 and the convex portion 42. According to this method, the game board mounting frame 2 and the game board 2
1 can be easily assembled and separated. FIG. 13 shows the hinge 4
FIG. 3 is an explanatory view showing a game board support mechanism by No. 3; In this method, if a hinge having a limited rotation range is used in advance, a mechanism (stopper) for simultaneously restricting the inclination angle of the game board 21 can be realized.

In the above embodiment, the left and right game board support mechanisms 26 are provided in symmetrical positions. However, it is not always necessary to provide two game board support mechanisms, and three or more game board support mechanisms are provided. It may be a thing. Furthermore,
The game board support mechanism may be provided horizontally on the entire lower side of the game board. If the game board support mechanism is provided at three or more places, the game board can be supported more stably, and if the game board support mechanism is provided on the entire lower side,
Further, the game board can be stably supported. However,
A mode in which the game board support mechanism is provided only in one place is not preferable, except for a case where the game board is not deviated in the left-right direction, such as a horizontally long mode in the lower side direction.

The stoppers provided on the game board mounting frame 2 are not provided at the upper part of the inside of the game board mounting frame 2 side, instead of the ones (28) extending vertically inside the side of the game board mounting frame 2 as shown in FIG. Game board 2
The function can be sufficiently exhibited even when only one upper portion is sandwiched. Further, as shown in FIG. 14, the stopper may be provided on the upper side of the game board mounting frame 2 downward (51). In such an aspect, it becomes easier to assemble and remove the game board from the game board mounting frame.

Further, as shown in FIG.
It is also possible to use a safety cord 52 or a wire. If the safety cord 52 and the like can be removed, it is easier to attach and remove the game board 21 to and from the game board mounting frame 2. In addition, if the pachinko gaming machine is provided with a level or the like, the determination of the angle of the gaming board can be made easier. Further, if a scale is provided in the game board shifting mechanism, the inclination angle of the game board can be quantitatively adjusted. Furthermore, if the game board shifting mechanism is an electric one, the inclination angle of the game board can be adjusted more easily.

[0033]

In the pachinko gaming machine according to the first aspect, since the gaming board is installed so as to be tiltable from the vertical posture, the winning probability of the pachinko gaming machine can be reduced by adjusting the inclination angle of the gaming board. Can be adjusted. Also,
Conventionally, it has been complicated to adjust the inclination angle of the pachinko gaming machine, and therefore, when adjusting the winning number of the entire hall, the inclination angle of the gaming board of the pachinko gaming machine is rarely adjusted. However, according to the present invention, since the inclination angle of the game board can be easily adjusted, by simply adjusting the inclination angle of the game board of each pachinko gaming machine,
It becomes possible to adjust the number of winnings in the entire hall.

Further, in the pachinko gaming machine of the present invention, since a mechanism for inclining the gaming board, which is a portion that actually needs to be inclined, is provided in the pachinko gaming machine, a special device is installed in the island facility of the hall. It is not necessary to use the conventional island equipment as it is. Since the pachinko gaming machine according to claim 2 is provided with the inclination angle adjusting means capable of operating the inclination angle of the game board, it is finer than the case where the inclination angle is adjusted by directly moving the game board. The angle can be easily adjusted.

According to a third aspect of the present invention, since the pachinko gaming machine includes the inclination angle fixing means for fixing the inclination angle of the game board at a constant value, the inclination angle of the game board is shifted after the inclination angle is adjusted. There is no end. Since the pachinko gaming machine according to the fourth aspect is provided with a fall-prevention angle limiting means capable of restricting the inclination angle of the game board to a certain range, the pachinko gaming machine can adjust the inclination angle of the game board, Even when the fixing means breaks down and the game board is freely rotated, the game board does not fall down.
