Description

The present invention relates to a gaming machine in which the front surface of a gaming machine main body is closed with a door panel.

A gaming machine represented by a pachinko gaming machine generally has a gaming machine main body in which a mechanism portion is accommodated and a door frame as a door panel that covers the front surface of the gaming machine main body. The door frame is supported in a cantilever manner by a hinge portion disposed on the left side of the gaming machine main body, and is opened toward the front side (front) with the hinge portion as a base portion.
In pachinko machines, a large window hole is formed in the door frame, and this window hole is closed with a glass plate. The pachinko gaming machine exposes the gaming surface of the gaming machine body through this window hole. For example, when a pachinko ball has a problem with the gaming surface, such as when a pachinko ball is caught by a game nail on the board, A hall clerk inserts a key into a key hole formed near the right side of the door frame in the opposite direction to the hinge portion to release the lock, and opens the door frame to the front side. Also, when inspecting the launching mechanism and the like disposed at the lower position of the game surface, the door frame is opened to the front side in the same manner for the inspection. Many gaming machines having such a mechanism can be seen, but Patent Document 1 is shown as an example.
JP 2004-329565 A

By the way, in recent pachinko machines, there is a tendency to design a large game surface particularly from the viewpoint of ease of visual recognition, realism at the time of game play, and further improvement of playability such as luxury. For this reason, the window hole of the door frame is configured to be large. Due to such changes in the door frame, several problems have been pointed out as follows.
1) As shown in FIGS. 11 (a) and 11 (b), the conventional door frame 120 has a relatively large margin around the window hole, so that the overhanging portion around the keyhole formed in the gaming machine main body 121 A notch portion 123 that engages with 122 is formed, whereby the door frame is supported on both sides of the opening / closing bracket as the opening / closing shaft portion and the overhanging portion 122. However, if the window hole is configured to be large as described above, there is no room for forming the notch 123. Therefore, there has been a demand for means that can firmly support the door frame on both the left and right sides without forming the notch 123.
2) The door frame was once separated at the lower position of the upper tray, and the lower side from the lower tray was configured separately. That is, the door frame was composed only of the portion above the upper tray. However, in recent models, the door frame is configured on a large board so as to include everything from the window hole to the lower tray. Furthermore, in order to give a luxury as compared with the conventional case, an electric decoration panel or the like disposed on the front surface of the door frame has been increased in size. As a result, the weight of the door frame tends to increase significantly. In particular, the door frame can be opened and closed in a cantilever manner with the opening / closing metal fitting as a base, and is thus easily distorted due to its large size and weight. Therefore, there has been a demand for means capable of supporting even if the door panel is somewhat deformed.
In addition, it was a problem common to gaming machines other than pachinko gaming machines in that the door frame was firmly supported despite the deformation of the door panel.
The present invention has been made paying attention to such problems existing in the prior art. An object of the present invention is to provide a gaming machine that can reliably support a door panel that can be opened and closed with a cantilever disposed on the front surface of the gaming machine main body together with an opening and closing shaft portion.

In order to achieve the above object, the invention of claim 1 comprises a gaming machine main body and a door panel supported in a cantilever manner by an opening / closing shaft portion disposed on either the left or right side of the gaming machine main body. In the gaming machine in which the front surface of the gaming machine main body is closed by the door panel, a first protrusion projecting forward is formed on the front surface of the gaming machine main body, and on the rear surface of the door panel. A second protrusion projecting rearward is formed, and the second protrusion is placed on the first protrusion when the door panel is closed. To do.
In order to achieve the above object, in the invention 2, in addition to the configuration of the invention described in claim 1, the first and second protrusions are on the opposite side to the side on which the opening / closing shaft portion is disposed. The gist is that it is formed at a position close to the side portion.
Further, in order to achieve the above object, in the invention 3, in addition to the configuration of the invention described in claim 1 or 2, the placement surface of the first protrusion and the placement surface of the second protrusion Is configured as a horizontal plane, and at least within the movement trajectory of the second protrusion when the door panel is opened and closed, both protrusions have at least one side of the same mounting surface or the mounting surface. The gist of the invention is that no interfering object protruding on the screen is arranged.
In order to achieve the above object, in addition to the configuration of the invention 3, in the invention 4, the front end upper part of the first protrusion and the rear end lower part of the second protrusion are respectively chamfered. The gist.
In order to achieve the above object, in the invention 5, in addition to the structure of the invention described in claim 1, at least one tip of the first and second protrusions is a front and rear of the door panel with respect to the gaming machine main body. The gist is that it is in contact with the back of the door panel or the front of the gaming machine main body at the correct closed position in the direction.
In order to achieve the above object, in the invention 6, in addition to the structure of the invention described in claim 1, a reinforcing plate is provided from the upper surface to the front surface of the first protrusion and from the lower surface to the rear surface of the second protrusion. The gist is that it is covered by.

In the above-described configuration, the door panel supported in a cantilever manner by the opening / closing shaft provided on either the left or right side of the gaming machine body is in the state where the door panel is closed with respect to the gaming machine body. The second protrusion is placed on the first protrusion, and the door panel is firmly supported together with the hinge portion in the closed state of the door panel. At this time, the first protrusion is formed at a desired position on the front surface of the gaming machine main body, and the second protrusion on the door panel side is just placed on the first protrusion with the door panel closed. Form in position. If it is supported by such opposing projections, it is sufficient to design the first and second projections so that they do not get in the way after the basic design of the door panel and the gaming machine body. There is no need to form a notch in the pachinko game machine, and the door panel can be firmly supported by the opening / closing shaft portion and both projections even if the window hole is configured to be considerably large in a pachinko machine.
Furthermore, since the door panel is supported if the second protrusion can be placed on the first protrusion, the door panel can be reliably supported in a closed state even if the door panel is slightly distorted. It becomes possible.

Here, it is preferable to form the mounting surface on the upper surface of the first protrusion and the mounting surface on the lower surface of the second protrusion so as to be horizontal planes. In that case, the same mounting surface and the mounting surface are in close contact with each other at the correct closed position of the door panel with respect to the gaming machine main body. However, if the second protrusion is placed on the first protrusion, the contact surfaces of the two protrusions are not necessarily flat. Further, the placement surface and the placement surface need not be horizontal.
Further, in the present invention, it is preferable that the positions of both protrusions are formed at a position close to the side opposite to the side on which the opening / closing shaft portion is disposed. This is because the door panel can be supported in a well-balanced manner by disposing both protrusions at a position close to the laterally opposite side portion as far as possible from the opening / closing shaft portion.

In the present invention, the upper surface of the first protrusion and the lower surface of the second protrusion are respectively provided with a mounting surface and a mounting surface that are horizontal planes, and at least when the door panel is opened and closed. In the movement trajectory of the protrusions, it is preferable that the protrusions do not have an interference object protruding on at least one side of the mounting surface side or the mounting surface side.
With such a configuration, since the placement surface and the placement surface are first horizontal planes, the stability of the placed second protrusion is improved. Also, in the opening / closing operation of the door panel with respect to the gaming machine main body, there is an interference object such as a reinforcing rib of the protrusion, which becomes an obstacle when the two surfaces approach and the surfaces are rubbed against each other. Since it is not formed, the door panel can be smoothly opened and closed.

In the present invention, it is preferable that the front end upper portion of the first protrusion and the rear end lower portion of the second protrusion are chamfered. Thus, even if the relative horizontal positions of the placement surface and the placement surface are slightly overlapped in the vertical direction, the second projection can be guided onto the first projection using the chamfered portion as a guide surface. It becomes easy, and it is possible to place the second protrusion on the first protrusion only by rotating the door panel in the closing direction without performing an auxiliary operation for slightly lifting the door panel.
In addition, as described above, since door panels tend to be heavier in recent years, there is a possibility that distortion over the door panel itself may occur due to aging. In general, such a distortion often causes the right side portion to be lowered if the door panel is supported by the opening / closing shaft portion on the left side portion. As a result of this distortion, the placement surface and the placement surface horizontal position of both protrusions overlap in the vertical direction.
However, by chamfering the upper front end of the first protrusion and the lower rear end of the second protrusion in this way, the second protrusion is guided onto the first protrusion with the chamfered portion serving as a guide surface. Therefore, even if the placement surface and the placement surface horizontal position are slightly overlapped in the vertical direction, the second protrusion can be mounted on the first protrusion only by rotating the door panel in the closing direction. The problem that both the protrusions interfere with each other and the door panel is difficult to close does not occur.
In the present invention, it is preferable that at least one tip of the first and second protrusions is in contact with the back surface of the door panel or the front surface of the gaming machine body at a correct closed position of the door panel in the front-rear direction with respect to the gaming machine body.
In such a configuration, the correct closing position of the door panel in the front-rear direction with respect to the gaming machine main body in a state in which the tip of the first or / and second projecting body is in contact with the back of the door panel or / and the front of the gaming machine main body Therefore, positioning is possible without providing other positioning means. Also, even if the player presses the door panel at this position, the first and / or second protrusions cannot be easily recessed as a kind of stick, and a recess is created by the recess. This also prevents fraudulent acts such as inserting wires into the gaming machine.

In the present invention, it is preferable that the first protrusion is covered with a reinforcing plate from the upper surface to the front surface and from the lower surface to the rear surface of the second protrusion.
In such a configuration, it is possible to reduce the impact due to wear due to aging and collisions between both protrusions. The reinforcing plate is preferably composed of a thin plate made of an alloy. Further, the chamfered shape formed on the protrusion may be realized by the shape of the reinforcing plate.

In the invention described in the above claims, the door panel supported in a cantilever manner by the opening / closing shaft portion disposed on either the left or right side of the gaming machine main body is closed with respect to the gaming machine main body. The second protrusion is placed on the first protrusion on the gaming machine body side, and in the closed state of the door panel, the door panel is reliably supported by the protrusion together with the opening / closing shaft portion. It becomes possible to do.

The first support protrusion 61 is disposed on the front wall surface of the main body frame 14 between the ball feeding unit 19 and the rotary body 23. Here, as shown in FIGS. 10A to 10C, the surface of the front plate 14a on which the first support protrusion 61 is projected is defined as a base position B1. Second support protrusion 6
3 is disposed on the back wall surface of the door frame 41 between the through hole 58 and the pachinko ball inlet 54. Here, as shown in FIGS. 9A to 9C, the surface of the back plate 41a on which the second support protrusion 63 is projected is defined as a base position B2. From the tip of the first support protrusion 61 to the base position B
The distance from 1 to the distance from the tip of the second support projection 63 to the base position B2 is the same length.

As shown in FIGS. 9A to 9C, the second support protrusion 63 is disposed at a position shifted upward by one support protrusion with respect to the first support protrusion 61 in the side view, In terms of design, the upper surface of the first support protrusion 61, that is, the upper surface position of the horizontal portion 67 b of the reinforcing plate 68 and the lower surface of the second support protrusion 63, that is, the lower surface position of the horizontal portion 67 b of the reinforcing plate 68 are horizontal. Match in position. However, in actuality, the door frame 41 that is cantilevered on the left side by the opening / closing metal fitting 44 slightly lowers due to its own weight on the right side, so that the first support protrusion 61 and the second support protrusion 63 slightly interfere with each other. Will be placed at the position.
Also, as shown in FIGS. 9B and 9C, the second support protrusion 63 is disposed above the first support protrusion 61 in a state where the door frame 41 is closed to the main body frame 14. It will be.

The operation of the first and second support protrusions 61 and 63 in such a configuration will be described.
The door frame 41 is closed from the opened state with respect to the main body frame 14 by turning in the closing direction with the opening / closing bracket 44 as a base.
As shown in FIGS. 9A and 10A, the second support protrusion 63 gradually approaches the first support protrusion 61 as the door frame 41 is closed. As shown in FIG. 9A, both protrusions 61,
Since 63 has shifted | deviated up and down in the side view, it does not collide from the front. However, since the lower surface of the second support protrusion 63 is disposed at a position that slightly interferes with the upper surface of the first support protrusion 61 as described above, as shown in FIG. With the closing of the second support protrusion 63, the second support protrusion 63 is gradually pushed up onto the first support protrusion 61 with the curved portions 67c serving as guide surfaces. That is, the door frame 41 is lifted up to a correct design position from a state where the entire door frame 41 is slightly lowered by its own weight. Then, as shown in FIGS. 9C and 10C, when the first support protrusion 61 is completely placed on the second support protrusion 63, the door frame 41 is lowered to the right. It will be correct | amended and will be correctly arrange | positioned in the front surface of the main body frame 14. FIG.

At this time, the rotating body portion 23 on the main body frame 14 side is inserted into the through hole 58 on the door frame 41 side, and the front keyhole is exposed on the front surface of the door frame 41 as shown in FIG. Further, the latch 57 on the door frame 41 side is inserted into the slit 22 and is latched with a latching portion (not shown), thereby preventing the door frame 41 from rotating in the opening direction. Further, the back plate 41 a of the door frame 41 contacts the contact surface 14 b around the front plate 14 a of the main body frame 14. In the state where the door frame 41 is closed in this way, the first and second support protrusions 61 and 63 are respectively opposed to the front plate 14a and the back on the opposite side, as shown in FIGS. 9 (c) and 10 (c). It contacts the face plate 41a.

By configuring as described above, the present embodiment has the following effects.
(1) The first and second support protrusions 61 and 63 are disposed at desired positions on the front plate 14a of the main body frame 14 and the rear plate 41a of the door frame 41, respectively, so that the door frame 41 together with the opening / closing bracket 44 is provided.
Can be firmly supported. Since the first and second support protrusions 61 and 63 can be disposed at desired positions of the main body frame 14 and the door frame 41, respectively, when the viewing window hole 42 is enlarged or other components are disposed, Even if the space of the back plate 41a is limited, it is easy to cope.
(2) Since the door frame 41 is slightly distorted to the right by its own weight, the lower surface of the second support protrusion 63 is disposed at a position that slightly interferes with the upper surface of the first support protrusion 61. However, the first and second support protrusions 61 and 63 are pushed up onto the first support protrusion 61 by closing the door frame 41 with the curved portions 67c serving as guide surfaces. Therefore, even if the door frame 41 is distorted as described above, it is not necessary for the operator to perform an auxiliary operation such as lifting the door frame 41, and the door frame 41 can be reliably supported.
(3) The upper surface side of the first support protrusion 61 and the lower surface of the second support protrusion 63 are each configured by a simple horizontal plane, and the second support protrusion 63 is placed on the first support protrusion 61. There are no protrusions that would interfere when placed. Therefore, the second support protrusion 63 is quickly guided onto the first support protrusion 61 simply by rotating the door frame 41 in the closing direction, and an operator needs to perform an auxiliary operation such as lifting the door frame 41. There is no. Further, since the door frame 41 approaches the main body frame 14 while rotating with the opening / closing bracket 44 as a base, the second support protrusion 63 is actually on the first support protrusion 61 from an oblique direction in plan view. It is supposed to be placed. Since there is no projection on the mounting surface and the mounting surface in this way, the mounting does not hinder the second support protrusion 63 approaching the first support protrusion 61 from any direction. .
(4) In the state where the door frame 41 is closed, the first and second support protrusions 61 and 63 are in contact with the front plate 14a and the back plate 41a on the opposite sides, respectively. However, it is difficult for the door frame 41 to be bent due to the stress to form a gap.
(5) The first and second support protrusions 61 and 63 are strong because they are reinforced by the reinforcing plate 68. In particular, since the curved portions 67c rub against each other as the guide surface as described above, it is preferable to provide the reinforcing plate 68 that is resistant to wear in this way.

The present invention can be implemented with the following modifications.
In the above embodiment, the first and second support protrusions 61 and 63 are provided with the reinforcing plate 68 to form the curved portion 67c as the guide surface.
Such a guide surface may be directly formed on the main bodies 65 and 63 when not mounted.
In the above description, the first and second support protrusions 61 and 63 are in contact with the front plate 14a and the back plate 41a on the opposite side in a state where the door frame 41 is closed. I do not care.
In the above embodiment, the main body frame 14 and the game board 27 are separate bodies, but they may be applied to an integrated model.
-In the above embodiment, it was applied to a so-called first type pachinko machine with a starter,
The type of pachinko machine is not particularly limited. In addition, if the gaming machine can support the door panel in a cantilever manner, it can be applied to a gaming machine other than a pachinko gaming machine such as a slot machine.
In addition, it is free to implement in a mode that does not depart from the spirit of the present invention.
