BACKGROUND OF THE INVENTION
The present invention relates to a gaming machine that prevents unauthorized devices from being manipulated by allowing unauthorized tools to enter the interior of a device through a gap between the lower surface of an inner frame and an outer frame.
[0002]
[Prior art]
In gaming machines such as pachinko machines, an inner frame is attached to an outer frame that constitutes the outer shell of the device body and is installed on the island facility. The inner frame is a game board, various control boards, and a glass frame. There are some which are provided with a support mechanism for preventing the inner frame from falling down because many parts such as a hitting ball supply tray are mounted and have a considerable weight.
[0003]
For example, in Japanese Patent Application Laid-Open No. 2001-129205, a support mechanism (slider device) incorporating a roller is attached to the lower end of the open end side of the inner frame (front frame) back surface, and the inner frame is closed. The inner frame is supported by riding on a stopper provided in the lower frame. In addition, in this support mechanism, the movable arm is rotated by providing a roller at the lower end of the movable arm that is rotated with the upper end side as a fulcrum and is biased by the elastic member in an unloaded state. The roller height is changed by (posture change). In addition, the movable arm is configured to support the maximum load of the inner frame by changing to an upright posture at the position where the inner frame is almost closed, where the roller contacts the standing wall (stop part) of the stopper, and lowering the position of the roller accordingly. It is. Thereby, the load applied to the roller during the inner frame closing operation in which the roller rolls on the stopper is reduced, the friction load is reduced, and the operability is prevented from being deteriorated before the closing is completed.
[0004]
[Problems to be solved by the invention]
However, in the conventional pachinko machine, a gap is provided between the lower frame upper surface of the outer frame and the lower surface of the inner frame in order to open and close the inner frame with respect to the outer frame. There is a problem that the device is easily operated illegally. In recent years, in order to improve decorativeness, reduce weight, reduce costs, etc., an increasing number of models use plastic parts for the inner part of the outer frame and the entire inner frame. In consideration of the deformation after assembly or the like, the gap needs to be set to be slightly larger. Therefore, there is a problem that the structure becomes weaker against the intrusion of unauthorized tools.
[0005]
On the other hand, in models equipped with a support mechanism for the inner frame, since the roller protrudes downward from the lower surface of the inner frame, a large gap is provided between the outer frame, and in addition, in the stopper part where the roller rides, The front end surface of the stopper that guides the roller is inclined downward to form a larger gap. Therefore, even in this configuration, there is a defect that unauthorized tools are likely to enter from the gap on the lower surface side of the inner frame, and improvement thereof is required.
[0006]
In consideration of the above facts, the present invention provides a gaming machine that prevents unauthorized equipment from being manipulated by allowing unauthorized equipment to enter the equipment through a gap between the inner frame and the outer frame. The issue is to provide.
[0007]
[Means for Solving the Problems]

A roller having a protruding portion, a riding surface on which the roller of the supporting means rides, an inclined surface that is inclined forward on the front side of the riding surface, and a rear end portion of the riding surface. A stopper portion that regulates the riding position; a substantially concave portion formed in the wall-like member; and a closing member that is provided in the support means and closes an upper surface of the substantially concave portion when the inner frame is closed. , have a, during occlusion of the inner frame, with said roller mounting member is received in said substantially concave portion rotates, said roller rides on the riding surface in contact with the stopper portion, the roller mounting The member is characterized by supporting the inner frame in a substantially vertical posture .
[0008]
According to the first aspect of the present invention, the inner frame is attached so that it can be opened and closed with the side end portion pivotally supported by the outer frame, and the game board can be attached to and detached from the front side. When the inner frame is closed with respect to the outer frame, in the closed state, the wall-like member provided along the width direction on the upper surface of the lower frame portion of the outer frame substantially contacts the lower part of the back surface of the inner frame, A gap formed between the upper surface of the lower frame portion and the lower surface of the inner frame is closed. If the lower frame portion of the outer frame is made of resin, the wall-like member can be integrally formed by molding. Furthermore, even if the inner frame is made of resin and the gap becomes large due to deformation or the like, the gap is reliably closed by the wall-like member.
[0009]
As a result, even if an unauthorized tool such as a piano wire enters the device from the gap on the lower side of the inner frame, the unauthorized device is blocked by the wall-like member and thus cannot be illegally operated. .
[0011]
Further, during the opening / closing operation of the inner frame, the support means provided on the inner frame is in contact with the upper surface of the lower frame portion of the outer frame to support the inner frame, so that the inner frame can be prevented from being lowered or deformed. Note that the configuration der because of its rollers provided with roller supporting means is in contact with the lower frame portion upper surface, the friction load in the inner frame opening and closing operations also will be reduced. Further, the portion corresponding to the support means of the wall member is provided with a substantially concave portion, and when the inner frame is closed, the support means is accommodated in the substantially concave portion, and the inner wall surface of the substantially concave portion is the inner wall surface of the inner frame. It will be in the state separated from the back. When the inner frame is closed and the support means is accommodated in the substantially concave portion, the open upper surface of the substantially concave portion is closed by the closing member provided on the support means.
[0012]
As a result, even if an unauthorized tool inserted from the lower surface of the inner frame tries to enter the inside of the device through the substantially concave portion, the unauthorized tool is blocked by the blocking member and cannot enter. As described above, by providing the wall-shaped member with the substantially concave portion that accommodates the support means, it is possible to reliably prevent the intrusion of unauthorized tools even in a configuration in which the upper surface of the substantially concave portion becomes an opening. .

[0021]
In this embodiment, the inner frame 14 is a resin molded product, and a back set 72 as a mechanism frame body provided with a control board 70 and the like is attached to the back surface 14A. Further, a concave portion 74 having an opening at the rear and the lower side is formed near the side surface 14B on the open end side, and a roller unit 76 is disposed in the concave portion 74.
[0022]
The roller unit 76 includes a metal attachment plate 78 that is disposed in the recess 74 and attached to the back surface 14 </ b> A of the inner frame 14. A support shaft 80 is inserted into the upper portion of the mounting plate 78, and a roller mounting member 82 formed in a U-shaped cross section by a sheet metal is rotatably attached to the support shaft 80. Further, the roller mounting member 82 is urged rearward (in the direction of arrow A in the figure) by a string spring 84 that is extrapolated to the support shaft 80.
[0023]
A rectangular flat plate-shaped closing plate 86 is provided on the tip end side of the roller mounting member 82. The closing plate 86 is configured to be substantially parallel to the lower surface 14C of the inner frame 14 when the roller mounting member 82 is pressed to the back surface 14A side (the direction opposite to the arrow A direction) to have a substantially vertical posture. ing. Further, the tip of the roller mounting member 82 is a bifurcated leg portion 88, and a roller 92 having a roller portion made of metal is rotatably attached to a roller shaft 90 fitted into the leg portion 88. ing. The roller 92 has a lower end projecting slightly below the lower surface 14C of the inner frame 14, and as described above, the roller mounting member 82 is configured to be in a substantially vertical posture so that the height thereof is lowered. .
[0024]
On the other hand, the outer frame 12 is made of wood, and a decorative plate 96 having an inverted L-shaped cross section that covers the front surface and the upper surface (the inner surface of the frame) of the lower frame portion 94 is attached to the lower frame portion 94. The decorative plate 96 is a molded product formed of the same resin material as the inner frame 14, and a wall portion 98 having a predetermined height is integrally provided along the width direction at the rear end portion of the upper surface 96A.
[0025]
The portion of the wall portion 98 corresponding to the roller unit 76 is a concave portion 100 that is bent backward in a concave shape, and a metal support plate 102 on which the roller 92 of the roller unit 76 rides on the concave portion 100. It is arranged.
[0026]
FIG. 5 shows an enlarged view around the concave portion 100. As shown in the drawing, the bottom surface of the concave portion 100 and its front region (a part of the upper surface 96A of the decorative plate 96) are opened to expose the upper surface 94A of the lower frame portion 94, and the support plate 102 is exposed to the exposed portion. A mounting portion 104 provided at each of the left and right end portions is attached by two countersunk screws 106. Further, the central portion of the support plate 102 is a riding surface 108 that is raised from the mounting portion 104, and the front side of the riding surface 108 is an inclined surface 110 that is inclined downward toward the front. Further, a stopper portion (standing wall) 112 for restricting the riding position of the roller 92 is provided substantially perpendicular to the riding surface 108 at the rear end portion of the riding surface 108.
[0027]
Further, the upper surface 96A of the decorative plate 96 is slightly higher than the riding surface 108, and the front side of the upper surface 96A is also an inclined surface 96B inclined downward to the front. Further, the front end portion of the inclined surface 96B in the region where the concave portion 100 is provided is a stepped portion 114 having substantially the same height as the front end portion of the inclined surface 110 of the support plate 102.
[0028]
Next, the operation of this embodiment will be described. FIG. 6 is a side sectional view of the outer frame 12 with the inner frame 14 closed, and FIGS. 7 to 9 are explanatory views showing the closing operation of the inner frame 14 at the roller unit 76 portion. .
[0029]
As shown in FIG. 6, except for the roller unit portion, when the inner frame 14 is closed, the lower part of the back surface 14A of the inner frame 14 contacts the wall portion 98 of the decorative plate 96 provided on the lower frame portion 94 of the outer frame 12. The gap 116 formed between the outer frame 12 (the upper surface 96A of the decorative plate 96) and the lower surface 14C of the inner frame 14 is closed. As a result, even if an unauthorized tool such as the piano wire P enters the device from the gap 116, the piano wire P is blocked by the wall 98 and cannot enter.
[0030]
Further, in the roller unit 76 portion, as shown in FIG. 7, when the opened inner frame 14 is pushed in the closing direction (arrow B direction in the figure), the roller 92 of the roller unit 76 is supported as shown in FIG. The plate 102 contacts the inclined surface 110 and moves toward the riding surface 108 while rolling on the inclined surface 110. When the inner frame 14 is completely closed, the roller 92 riding on the riding surface 108 is housed in the concave portion 100 and is brought into contact with the stopper portion 112 of the support plate 102 to be positioned on the riding surface 108. . Further, the roller mounting member 82 rotates in the direction of arrow C in the figure against the urging force of the coiled spring 84 with the support shaft 80 as a fulcrum, and assumes a substantially vertical posture.
[0031]
As a result, the inner frame 14 is supported on the upper surface (support plate 102) of the lower frame portion 94 of the outer frame 12 via the roller unit 76, and is lowered or deformed by mounting heavy components such as the game board 32. Is suppressed. When the amount of deformation of the inner frame 14 increases, for example, the gap between the inner frame 14 and the outer frame 12 on the side surface portion may increase, which may cause inconvenience such as easy entry of unauthorized tools. In the embodiment, the above configuration enhances the prevention of intrusion of unauthorized tools.
[0032]
Further, when the inner frame 14 is opened and closed, the roller 92 rolls on the support plate 102, so that the frictional load is reduced. Further, during the closing operation of the inner frame 14 in which the roller 92 rolls on the riding surface 108, The load of the inner frame 14 applied to the roller 92 is lightened when the roller mounting member 82 is inclined. Then, at the substantially closed position of the inner frame 14, the roller 92 contacts the stopper portion 112 of the support plate 102, and the roller mounting member 82 changes to a substantially upright posture to support the load of the inner frame 14 at the maximum. For this reason, an increase in the frictional load before closing is suppressed, and the operating force during closing can be reduced.
[0033]
When the inner frame 14 is closed, the opened upper surface of the concave portion 100 is closed by the closing plate 86 of the roller unit 76. As a result, even if the piano wire P inserted from the gap 116 tries to enter the inside of the device through the concave portion 100 of the wall portion 98, the piano wire P is blocked by the closing plate 86 and cannot enter.
[0034]
As described above, in the pachinko machine 10 according to the present embodiment, the gap 116 between the outer frame 12 formed on the lower surface 14C side is closed while the inner frame 14 is closed. Unauthorized tools such as P cannot enter the device, and unauthorized operation of the device is prevented.
[0035]
In this embodiment, the concave portion 100 that houses the roller unit 76 is provided in the wall portion 98 so that the upper surface of the concave portion 100 is an opening. Since it is blocked by the blocking plate 86, it is possible to reliably prevent the intrusion of unauthorized tools.
[0036]
In the above-described embodiment, when the inner frame 14 is closed, the back surface 14A of the inner frame 14 is completely in contact with the wall portion 98 on the outer frame 12 side to close the gap 116. However, when the inner frame 14 is a resin molded product as in the present embodiment, there is a concern that the blockage of the inner frame 14 may deteriorate due to accumulation of warpage, assembly errors, and the like. Therefore, for example, a structure (substantially abutting state) is provided between the back surface 14A of the inner frame 14 and the wall portion 98 so that an unauthorized tool cannot pass therethrough so as to avoid such a problem. May be.
[0037]
In addition, the shape of the concave portion 100 provided on the wall portion 98 and the closing plate 86 that closes the upper surface thereof may be other than the rectangular shape as in the present embodiment. For example, the concave portion is formed in a curved shape and is substantially elliptical. A combination of blocking plates can also be used. The present invention can also be applied to a model that does not use a roller unit as in this embodiment.
[0038]
【The invention's effect】
Since the gaming machine of the present invention has the above-described configuration, it is possible to prevent an unauthorized tool from entering a device through a gap between the inner frame and the outer frame formed on the lower surface side of the inner frame, thereby preventing the device from being illegally operated.
