Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine having a main set board rotatable with respect to a mechanical board.

[0002]

2. Description of the Related Art Conventionally, a prize ball of a pachinko machine is paid out to an upper plate, and is paid out to a lower plate only when the upper plate is full of pachinko balls. For example, in the pachinko machine 100 shown in FIG. 5, when a pachinko ball enters any of the winning ports on the game board 103, a predetermined number of prize balls are paid out to the upper plate 104 fixed to the inner frame 101. When the upper plate 104 becomes full of pachinko balls and it becomes impossible to pay out the prize balls to the upper plate 104, the prize balls that cannot be paid out are fixed to the inner frame 101. It is paid out to the set lower plate 102.

Here, a mechanism for paying out the prize balls will be described with reference to a rear view of the pachinko machine 100 shown in FIG. First, the prize balls paid out to the upper plate 104 (see FIG. 5) or the lower plate 102 (see FIG. 5) are stored in the prize ball tank 122. The prize balls stored in the prize ball tank 122 are allowed to pass a predetermined number by the prize ball payout device 123 and flow to the upper plate 104 (see FIG. 5). As a result, the prize ball is paid out to the upper plate 104 (see FIG. 5).

However, at this time, the upper plate 104 (see FIG. 5)
If the entrance to the passage to is blocked by a pachinko ball,
The prize ball flows to the prize ball discharge port 125. Since the prize ball discharge port 125 communicates with the lower plate box 127 fixed to the back side of the inner frame 101, the prize ball discharge port 12
The prize ball which has flowed to No. 5 falls into the lower plate box 127.
Furthermore, since the lower plate box 127 is in communication with the lower plate 102 (see FIG. 5), the winning balls that have fallen into the lower plate box 127 flow to the lower plate 102 (see FIG. 5). As a result, award balls that cannot be paid out to the upper plate 104 (see FIG. 5) are paid out to the lower plate 102 (see FIG. 5).

[0005] A mechanism for paying out such a prize ball is shown in FIG.
The main set board 120 shown in FIG. As shown in FIG. 6, the main set board 120 is rotatably supported by a mechanism board 110 fixed to the back side of the inner frame 101 via a hinge 121 provided with a rotating shaft.

As shown in FIG. 8, a plurality of mounting holes 111 are provided around an opening 112 to which the game board 103 (see FIG. 5) is mounted. And is fixed to the back side of the inner frame 101. A hinge 115 having a rotation hole is provided on one of the side surfaces. As shown in FIG. 9, the hinge 121 of the main set plate 120 is turned to the rotation hole of the hinge 115 of the mechanism panel 110. By inserting the driving shaft,
A main set board 120 is rotatably supported by the mechanism board 110.

However, when the main set board 120 is rotatably supported with respect to the mechanism board 110, when the main set board 120 is closed with respect to the mechanism board 110, the relative position between the main set board 120 and the mechanism board 110 is increased. It is necessary to provide a means for accurately assuring a proper positional relationship. Because a large number of pachinko balls are stored in the prize ball tank 122 (see FIGS. 6 and 7) of the main set board 120,
This is because a large rotational moment always acts on 0.

Therefore, as shown in FIG. 7, in the main set board 120, two projections 125 are formed on the back side of the prize ball tank 122, and as shown in FIG. The two through holes 114 are formed, and the projections 125 of the main set board 120 fit into the through holes 114 of the mechanism board 110 when the main set board 120 is closed with respect to the mechanism board 110. Thus, the relative positional relationship between the main set board 120 and the mechanism board 110 is accurately ensured.

As a result, for example, the lower back surface portion 116 of the mechanism board 110 (see FIGS. 8 and 9) is
0 in contact with the flat portion 126 (see FIG. 9).
The opening 113 (see FIGS. 8 and 9) of the main set board 120 accurately communicates with the opening 124 (see FIG. 9) of the main set board 120 and prevents a step or the like from occurring in the communicating portion.
The pachinko ball missed by the dial 105 (see FIG. 5) is lowered through the opening 113 (see FIGS. 8 and 9) of the mechanism board 110 and the opening 124 (see FIG. 9) of the main set board 120. Returning to the plate 102 (see FIG. 5) can be performed without hindrance.

[0010]

However, as shown in FIG. 7, the protrusion 125 of the main set board 120 is
Considering the ease of positioning between the main set board 120 and the mechanism board 110, the shape is cylindrical, so that
Since the cross-sectional area is not large enough, and the rotational moment of the main set board 120 acts as a concentrated load, the strength may not be sufficiently secured.

Further, the projection 1 of the main set board 120
25 is formed at a position away from the rotation axis of the hinge 121 in consideration of the positioning accuracy of the main set board 120 and the mechanism board 110, and so on.
Even if a large rotational moment does not act on zero, if the mounting error between the main set board 120 and the mechanical board 110 is large, when the main set board 120 is closed with respect to the mechanical board 110, the protrusion of the main set board 120 The object 125 may be press-fitted into the through hole 114 of the mechanism panel 110, and a state in which the strength of the protrusion 125 of the main set panel 120 is insufficient may be promoted.

In recent years, not only the main set board 120 but also the mechanical board 110 are often molded with resin.
Therefore, even when the mechanism board 110 is also formed of resin, the main set board 120 is moved to the mechanical board 1 due to dimensional errors due to the resin molding between the mechanism board 110 and the main set board 120.
When the main set board 120 is closed, the protrusion 125 of the main set board 120 may be pressed into the through hole 114 of the mechanism board 110, which may promote insufficient strength of the protrusion 125 of the main set board 120. Was.

The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to provide a pachinko machine which eliminates a concern about insufficient strength of a positioning mechanism between a main set board and a mechanism board. I do.

[0014]

According to a first aspect of the present invention, there is provided a pachinko machine, which is provided with a game board fixed to an inner frame and having a game board and a shooting rail mounted thereon, A main set board rotatably supported with respect to the board, and a winning ball discharge port provided on the main set board, and when the main set board is closed with respect to the mechanism board, the In a pachinko machine in which a lower back surface of a mechanism board is in contact with a flat portion of the main set board, an elongated perforated portion formed on a lower back face of the mechanical board and a flat portion of the main set board. And a formed elongated projecting piece, wherein when the main set board is closed with respect to the mechanism board, the projecting piece is inserted into the perforated portion, while the main set When the board is opened, the projecting pieces Characterized in that the outside vent from serial perforations.

According to a second aspect of the present invention, in the pachinko machine according to the first aspect, the mechanical board and the main set board are resin-molded.

According to a third aspect of the present invention, in the pachinko machine according to the first or second aspect, the projecting piece is formed above the prize ball discharge port.

The pachinko machine of the present invention having such a configuration has a main set board and a mechanism board. The mechanism board has a frame-like shape for mounting the game board, but the lower back surface of the mechanism board is below the position where the game board is mounted, and behind the position where the firing rail is mounted. Therefore, a flat portion is widely secured. Therefore, the perforated portion can be formed in an elongated shape on the lower back surface of the mechanism panel.

On the other hand, the flat portion of the main set board which is in contact with the lower back surface of the mechanism board can be widely secured because it is located below the game board. Therefore, the protruding piece can be formed in an elongated shape on the flat portion of the main set board.
In this regard, the protruding piece of the main set board is elongated,
Compared with the protrusion of the main set board of the prior art, the cross-sectional area can be increased and the rotational moment of the main set board can be dispersed.

Therefore, when the main set board is closed with respect to the mechanical board, the projecting piece of the main set board is inserted into the perforated portion of the mechanical board, so that the main set board can be positioned with respect to the mechanical board. Compared with the protrusions of the main set board of the prior art, the shear force generated on the projecting piece of the main set board is small, and the rotational moment of the main set board is concentrated load, like the protrusion of the main set board of the prior art. , But acts as a distributed load. When opening the main set board for the mechanical board,
The projecting piece of the main set board comes off from the perforated part of the mechanism board.

That is, in the pachinko machine of the present invention, the elongated projecting piece formed on the plane portion of the main set board is inserted into the elongated hole formed on the lower back surface of the mechanism board. By being put in and out,
The main set board and the mechanism board constitute a positioning mechanism, and the protruding pieces of the main set board are elongated compared to the protruding pieces of the main set board of the prior art because the protruding pieces of the main set board are elongated. The cross-sectional area of the main set board can be increased, and the rotational moment of the main set board can be applied to the projecting piece of the main set board like a distributed load. The strength of the positioning mechanism of the board can be increased, and the concern about insufficient strength of the positioning mechanism of the main set board and the mechanism board can be eliminated.

In the case where the mechanical panel and the main set panel are formed of resin, when the main set panel is closed with respect to the mechanical panel, due to a dimensional error due to the resin molding of the mechanical panel and the main set panel, etc. In this case, the projecting piece of the main set board comes into pressure contact with the perforated portion of the mechanism board, which may promote insufficient strength of the positioning mechanism between the main set board and the mechanism board, so that the above-described effect is further enhanced.

Further, in order to form the protruding piece in an elongated shape, it is necessary to secure a plane portion of the main set board with a predetermined width, which is a great limitation in designing the main set board. The space above the prize ball outlet on the main set board must be reserved for the passage of the prize ball,
Because it is a prerequisite for the design of the main set board, it is necessary to form an elongated projection piece by overlapping the space for the prize ball passage above the prize ball discharge port of the main set board. If the main set board is secured with a flat surface, the constraints for forming the protruding pieces in an elongated shape overlap with the prerequisites for designing the main set board in terms of space. Can be minimized.

[0023]

Embodiments of the present invention will be described below with reference to the drawings. The embodiment of the present invention is an improvement of the pachinko machine 100 (see FIGS. 5 and 6) described in the section of the prior art. Therefore, here, the common points with the prior art pachinko machine 100 have already been described in the section of the prior art, so that they will be omitted, and the differences from the conventional pachinko machine 100 will be described in detail.

In the embodiment of the present invention, the mechanism board 110 and the main set board 120 are improved. As for the mechanical board 110, as shown in FIG.
(See FIG. 5), it has a frame-like shape with an opening 112, but the lower back 1
16 is located below the position where the game board 103 (see FIG. 5) is attached and behind the position where the firing rail (not shown) is attached, so that a flat portion is widely secured. Therefore, in the embodiment of the present invention,
As shown in FIG. 1 and FIG.
Although the perforated portion 20 is formed in the 16, the perforated portion 20 is allowed to be formed in an elongated shape because the lower rear surface portion 116 of the mechanism panel 110 is widely secured.

On the other hand, as shown in FIG. 9, the flat portion 126 of the main set board 120 which is in contact with the lower back face 116 of the mechanism board 110 is also located below the game board 103 (see FIG. 5). Therefore, it can be widely secured. Therefore, in the embodiment of the present invention, as shown in FIG. 1, although the projecting piece 10 is formed on the flat portion 126 of the main set plate 120, the flat portion 126 of the main set plate 120 is also widely secured. It is allowed to form the protruding piece 10 in an elongated shape. Further, since the protruding piece 10 of the main set board 120 is elongated, the cross-sectional area can be increased as compared with the projection 125 (see FIG. 7) of the main set board 120 of the related art, and the rotational moment of the main set board 120 can be increased. Can be dispersed.

When the main set board 120 is closed with respect to the mechanism board 110, the main set board 120 rotates about a rotation axis 130 as shown in FIG. At this time, the protruding piece 10 of the main set board 120 is inserted into the perforated portion 20 of the mechanism board 110, moving upward in FIG. As a result, the main set board 120 is positioned with respect to the mechanism board 110, but has a larger cross-sectional area than the projection 125 of the conventional main set board 120 (see FIG. 7). The shear force generated in the main set plate 120 is small, and the rotational moment of the main set plate 120 does not act as a concentrated load as in the protrusion 125 (see FIG. 7) of the main set plate 120 of the prior art, but instead acts as a distributed load. Act as FIG.
Are the mechanical board 110 and the main set board 120 at this time.
Is shown in cross section.

On the other hand, when the main set board 120 is opened with respect to the mechanism board 110, the main set board 120 rotates about the rotation axis 130, and moves downward in FIG. The protruding piece 10 of 120 is pulled out of the perforated portion 20 of the mechanism panel 110.

That is, in the embodiment of the present invention, the elongated protruding piece 10 formed on the flat portion 126 of the main set board 120 is replaced with the elongated perforated hole formed on the lower back face 116 of the mechanism board 110. The main set board 120 is inserted and removed with respect to the section 20.
And a positioning mechanism for the mechanism board 110 (see FIG. 3), and since the protruding piece 10 of the main set board 120 is elongated, the main set board 120 according to the prior art is formed.
7, the cross-sectional area of the protruding piece 10 of the main set board 120 can be made larger than that of the protruding piece 125 (see FIG. 7). , And a distributed load, it is possible to increase the strength of the positioning mechanism between the main set board 120 and the mechanism board 110 as compared with the prior art, and to position the main set board 120 and the mechanism board 110. Concerns about insufficient strength of the mechanism can be resolved.

The mechanism panel 110 and the main set panel 12
When the main set plate 120 is closed with respect to the mechanical panel 110 due to a dimensional error due to the resin molding of the mechanical panel 110 and the main set panel 120, when the main set panel 120 is closed. Since the protruding piece 10 comes into pressure contact with the perforated portion 20 of the mechanism panel 110, which may promote insufficient strength of the positioning mechanism between the main set panel 120 and the mechanism panel 110, the above-described effect is further enhanced.

Further, in order to form the protruding piece 10 in an elongated shape, it is necessary to secure the plane portion 126 of the main set board 120 with a predetermined width, which is a great restriction in designing the main set board 120. Becomes However, the space above the prize ball discharge port 125 of the main set board 120 must be ensured for the passage of the prize ball, which is a prerequisite for designing the main set board 120. Therefore, in the embodiment of the present invention, as shown in FIG. 1, the elongated projecting piece 10 is overlapped with the space for the passage of the prize ball above the prize ball discharge port 125 of the main set board 120. Since the flat portion 126 of the main set board 120 for forming the main set board 120 is secured, and the restriction for forming the protruding piece 10 in an elongated shape overlaps with the design premise of the main set board 120 in terms of space. The restrictions on designing the main set board 120 are minimized.

The present invention is not limited to the above embodiment, and various changes can be made without departing from the gist of the present invention. For example, in the embodiment of the present invention, the elongated perforated portion 20 is formed on the lower rear surface portion 116 of the mechanism panel 110, and the elongated projecting piece 10 is
20 was formed on the plane portion 126, but on the contrary,
The elongated perforated portion 20 is formed on the flat portion 1 of the main set board 120.
26 and the elongated protruding piece 10 formed on the lower back surface 116 of the mechanism panel 110, the above-described effects can be obtained.

[0032]

According to the pachinko machine of the present invention, the elongated projecting piece formed on the plane portion of the main set board is inserted into the elongated hole formed on the lower back surface of the mechanism board. The main set board and the mechanism board constitute a positioning mechanism by being inserted and removed, and the projections of the conventional main set board are formed by the elongated protruding pieces of the main set board. Compared to conventional, since the cross-sectional area of the protruding piece of the main set board can be made larger and the rotational moment of the main set board can act on the protruding piece of the main set board like a distributed load, Compared with technology, it is possible to increase the strength of the positioning mechanism between the main set board and the mechanism board, and to eliminate concerns about insufficient strength of the positioning mechanism between the main set board and the mechanism board It can be.

When the mechanism board and the main set board are formed by resin molding, when the main set board is closed with respect to the mechanism board due to a dimensional error due to mutual resin molding of the mechanism board and the main set board. In this case, the projecting piece of the main set board comes into pressure contact with the perforated portion of the mechanism board, which may promote insufficient strength of the positioning mechanism between the main set board and the mechanism board, so that the above-described effect is further enhanced.

Further, in order to form the protruding piece in an elongated shape, it is necessary to secure a plane portion of the main set board with a predetermined width, which is a great limitation in designing the main set board. The space above the prize ball outlet on the main set board must be reserved for the passage of the prize ball,
Because it is a prerequisite for the design of the main set board, it is necessary to form an elongated projection piece by overlapping the space for the prize ball passage above the prize ball discharge port of the main set board. If the main set board is secured with a flat surface, the constraints for forming the protruding pieces in an elongated shape overlap with the prerequisites for designing the main set board in terms of space. Can be minimized.
