However, the member may be the main body frame 20 or the game board 30. Needless to say, it can be appropriately changed according to the design. Moreover, although the structure of the cover member sealing structure 91 is demonstrated in the figure, it cannot be overemphasized that the cover member sealing structure 92 also has an equivalent structure.

  In the figure, the cover member sealing structure 91 has a cover member side sealing portion 91a formed by recessing a corner portion of the cover member 90, and a convex portion protruding in a substantially semi-cylindrical shape on the opposite side of the cover member 90. It is comprised from the mechanism board side sealing part 91b. And the through-hole 91a1 which penetrates the screw | thread 130 is formed in the cover member side sealing part 91a. The shaft portion of the screw 130 is formed with a male screw portion 130a only at the tip, and an extension portion 130b in which no male screw is formed in the middle. On the other hand, the mechanism plate side sealing portion 91b is fitted with a cylindrical insert nut 91b2 having a female screw portion 91b1 formed on the inner peripheral surface thereof. The length of the insert nut 91b2 is slightly smaller than the extension portion 130b. And a donut-shaped leaf spring member 91b3 is inserted further into the insert nut 91b2.

  In the above configuration, when the cover member side sealing portion 91a is aligned with the mechanism plate side sealing portion 91b and the cover member side sealing portion 91a and the mechanism plate side sealing portion 91b overlap, the cover member The screw 130 is inserted into the through hole 91a1 of the side sealing portion 91a and screwed into the insert nut 91b2. When the screw 130 is rotated, the male screw portion 130a is screwed into the female screw portion 91b1 of the insert nut 91b2, but since the extension portion 130b is formed on the screw 130, the male screw portion 130a is at the same time. The screw part 130a penetrates the insert nut 91b2. Further, at the time of penetration, the male screw portion 130a also penetrates the leaf spring member 91b3, and is urged backward by the leaf spring member 91b3. The state immediately after the penetration is a sealed state in which the cover member 90 and the mechanism plate 80 are sealed.

Thereafter, even if the cover member 90 is removed from the mechanism plate 80 and the screw 130 is rotated in the reverse direction, the male screw portion 130a is urged in the back direction by the leaf spring member 91b3, so the insert nut 91b2 It is not screwed into the female thread portion 91b1. For this reason, the screw 130 cannot be removed, and the cover member 90 cannot be removed from the mechanism plate 80. The only way to open the cover member 90 as needed is to break either or both of the resin cover member side sealing portion 90a and the mechanism plate side sealing portion 91b. Here, since the cover member sealing structures 91 and 92 are disposed at positions that can be directly seen from the back side of the pachinko gaming machine 1, they are easily seen when the pachinko gaming machine 1 is opened for maintenance. it can. Accordingly, the cover member side sealing portion 90a and the mechanism plate side sealing portion 90b of the cover member sealing structures 91 and 92 are damaged in order to add a hand to the substrate box covered with the cover member 90. If fraudulent activity is performed, it can be detected at the next maintenance.

  In such a case, it is necessary to open the main body frame 20 in order to visually recognize the back side of the pachinko gaming machine 1. Since the operation of opening the main body frame 20 is performed in the case of maintenance after the store is closed or holiday maintenance, an illegal act such as damaging the cover member side sealing portion 90a or the mechanism plate side sealing portion 90b is performed. In such a case, there is a problem that it cannot be discovered until the main frame 20 is opened. On the other hand, after closing the hall, the hall operator goes around the hall, cleans the game board 30, adjusts nails arranged on the game board 30, and takes measures for clogging of the balls. There are many opportunities to open. Therefore, when the glass door frame 60 is opened, if the sealing state of the cover member sealing structures 91 and 92 is made recognizable, the glass door frame 60 can be opened only with respect to the cover member sealing structures 91 and 92. This is preferable because it is possible to detect fraud. Therefore, in the present embodiment, an opening in which the cover member sealing structure 91 is visible from the front side to the back side of the main body of the pachinko gaming machine 1 is provided in a region facing the back side of the glass door frame 60, When the glass door frame 60 is opened to perform various operations that are normal operations after the store is closed, the cover member side sealing portion 90a and the mechanism plate side sealing portion 90b of the cover member sealing structure 91 are sealed. A configuration is adopted in which the stop state can be recognized by visual recognition.

(2) Configuration in which the cover member sealing structure is visible:
FIG. 5 is a perspective view of a state in which the glass door frame 60 of the pachinko gaming machine 1 is opened. In the same figure, the state which opened the glass door frame 60 is shown. When the glass door frame 60 is opened, the main body frame 20 that is attached to the outer frame 10 and in which the game area 31 is opened in a substantially circular shape appears. In the present embodiment, an opening 150 that penetrates from the front surface to the back surface of the pachinko gaming machine 1 is formed in the main body frame 20. The opening 150 is formed at a position facing the cover member sealing structure 91 disposed on the back surface of the pachinko gaming machine 1, and is formed on the main body frame 20, the game board 30, and the mechanism board 80 as necessary. It is comprised by the formed opening shape. FIG. 6 shows an enlarged view of the opening 150 when viewed from the front.

  Thus, since the cover member sealing structure 91 is visible through the opening 150, the worker in the hole opens the glass door frame 60 and seals the cover member from the opening 150. By visually recognizing the structure 91, the sealing state of the cover member sealing structure 91 can be recognized. As a result, after closing the store, the hall can be visited and the cover member sealing structures 91 and 92 can be destroyed and the cover member 90 can be opened while performing the various operations described above, and the illegal acts performed on the board box can be checked. It becomes possible, and it becomes possible to detect fraudulent acts on the board box that can be performed even during business operations at an early stage. In the present embodiment, a resin transparent cover 150a is fitted into the opening 150, and dust or the like enters the back surface from the front surface of the pachinko gaming machine 1 through the opening 150 without blocking the view. To prevent that. Here, the transparent cover 150a may be formed of a convex lens to have a magnifying glass function. Accordingly, it is possible to enlarge and visually recognize the cover member sealing structure 91, and it is easy to confirm the sealing state of the cover member sealing structure 91, which is preferable.

In embodiment mentioned above, the structure which visually recognizes the sealing state of the cover member sealing structure 91 through the opening part 150 was employ | adopted. When the cover member sealing structure 91 is made of a transparent resin, an illegal act such as damage to the cover member side sealing portion 90a or the mechanism plate side sealing portion 90b is performed. It is easy to visually recognize the state. However, since the back surface of the pachinko gaming machine 1 is dark, it is not always easy to visually recognize the cover member sealing structure 91. Therefore, it is preferable that the sealing state of the cover member sealing structure 91 can be clearly seen by irradiating the cover member sealing structure 91. FIG. 7 is a configuration diagram showing an example of a configuration capable of irradiating the cover member sealing structure 91 in this way.

  In the figure, an LED substrate 160 in which LEDs 161 are disposed on a substrate is disposed at a predetermined position of a mechanism plate 80 near the cover member sealing structure 91. And the cover member sealing structure 91 is irradiated by making this LED161 emit light. Then, as shown in FIG. 8, the cover member sealing structure 91 that can be visually recognized through the opening 150 is illuminated by the light emission of the LED 161, and the worker in the hall is exposed to the light emission of the LED 161. By visually recognizing the member sealing structure 91, the sealing state can be easily recognized.

  On the other hand, the timing when the worker in the hall visually recognizes the sealed state of the cover member sealing structure 91 is when the glass door frame 60 is opened in the above-described embodiment. Therefore, it is preferable that the control process is executed so that the LED 161 emits light only when the glass door frame 60 is opened, which can contribute to power saving. FIG. 9 is a flowchart showing the processing contents of the LED control processing executed by the CPU of the control board housed in the board box. Here, in such a case, it is assumed that a predetermined sensor capable of detecting the opening of the glass door frame 60 is input to the control board. In the same figure, the state of the sensor mentioned above is detected, and the open / closed state of the glass door frame 60 is acquired (step S100). And it is discriminate | determined whether the glass door frame 60 is an open state (step S105), and if it discriminate | determines that it is an open state, the cover member sealing structure 90 will be irradiated by light-emitting LED161 (step S110). ).

  Here, in embodiment mentioned above, the structure which raises the cover member sealing structure 90 at the time of visual recognition by irradiating the cover member sealing structure 91 by light emission of LED161 was employ | adopted. Thus, in order to make it easy to visually recognize the cover member sealing structure 90, the method of raising the surface is not limited to the method of irradiating with the LED 161. For example, as shown in FIG. 10, the cover member sealing structure 91 may be easily lifted up by applying a fluorescent paint 162 to the side facing the opening 150 of the cover member sealing structure 90. .

In the embodiment described above, the cover member side sealing portion 90a formed with the cover member sealing structures 91 and 92 on the cover member 90 side, the mechanism plate side sealing portion 90b formed on the mechanism plate 80 side, and so-called one-way. A method of sealing the cover member 90 against the back surface of the pachinko gaming machine 1 by sealing the cover member 90 and the mechanism plate 80 by the screw 130 constituting the screw is shown. Thus, the method for sealing the cover member 90 to the mechanism plate 80 is not particularly limited, and can be selected as appropriate. FIG. 11 is a cross-sectional configuration diagram illustrating an example of another method that is preferably used for the cover member sealing structures 91 and 92. In the figure, an operating element holding portion 91a2 is formed in the cover member side sealing portion 91a. Here, the operation element holding portion 91a2 is formed with a substantially rectangular through hole 91a3 penetrating from the cover member 90 side toward the mechanism plate 80 side. The substantially square-shaped through hole 91a3 is formed so that the substantially square-shaped opening formed on the cover member 90 side is larger than the substantially square-shaped opening formed on the mechanism plate 80 side. It has a substantially trapezoidal shape.

That is, the inner peripheral surface of the through hole 91a3 is formed in a tapered shape such that the opening diameter becomes narrower from the cover member 90 side toward the back. On the other hand, the resin operation element 170 is formed of a transparent resin in a substantially dish shape having a size that can be inserted into the through hole 91a3, and the surrounding wall surface follows the tapered shape of the inner peripheral wall surface of the through hole 91a3. It is formed in the inclined surface which becomes narrow gradually toward the front.

  A metal engagement piece 170a bent in a substantially U-shaped cross section is held inside the substantially dish-like shape. The metal engagement piece 170a is formed by bending a strip-shaped plate material into a substantially U-shaped cross section and folding both ends inward at an acute angle. With this configuration, the resin operation element 170 is inserted into the through hole 91a3 of the operation element holding part 91a2 while holding the metal engagement piece 170a. At this time, a substantially dish-shaped portion of the resin operation element 170 is fitted into the through hole 91a3, and the resin operation element 170 is held by the operation element holding portion 91a2. On the other hand, on the mechanism plate 80 side, a fixed receiving structure 91b4 as the mechanism plate side sealing portion 91b is formed at a position facing the operation element holding portion 91a2 formed as the cover member side sealing portion 91a.

  The fixed receiving structure 91b4 is formed in a substantially quadrangular pillar shape, and is opened from the cover member 90 side to the opposite side. An engagement piece support portion 91b5 that connects the opposite side from the back side of the substantially quadrangular column shape is formed at the approximate center of the substantially quadrangular column shape while standing from the back side to the near side. . The engagement piece support portion 91b5 is formed in a substantially trapezoidal cross section having a long side opposite to the cover member 90 side. In such a configuration, when sealing the cover member 90 with respect to the mechanism plate 80, the through hole 91a3 formed as the operation element holding portion 91a2 of the cover member side sealing portion 91a is fixed to the mechanism plate side sealing portion 91b. Align so as to overlap the opening of the structure 91b4. Next, the resin operation element 170 is inserted from above the through hole 91a3, and enters the through hole 91a3 and the fixed receiving structure 91b4. Then, the folded end 170b formed at the tip of the metal engagement piece 170a engages with the long side portion of the engagement piece support portion 91b5 while moving on the inclined surface of the engagement piece support portion 91b5. As a result, the cover member 90 and the mechanism plate 80 are sealed.

  Thus, by sealing the cover member 90 and the mechanism plate 80, the cover member 90 is sealed against the back surface of the pachinko gaming machine 1. Here, the above-described fixed receiving structure 91b4 is formed in a substantially quadrangular pillar shape, and is opened from the cover member 90 side to the opposite side. Therefore, the engagement piece support portion 91b5 can be contacted from the opening on the mechanism plate 80 side. In this way, when it is possible to contact the engagement piece support portion 91b5, the folded end 170b of the metal engagement piece 170a can be detached from the engagement piece support portion 91b5. Accordingly, in the present embodiment, the opening on the mechanism plate 80 side of the fixed receiving structure 91b4 is covered with a fixed portion cover member 91b6 formed in a substantially rectangular parallelepiped. If this fixed portion cover member 91b6 is fixed to the inner peripheral surface of the opening of the fixed receiving structure 91b4 with an adhesive or the like, it is impossible to contact the engagement piece support portion 91b5 from the opening on the mechanism plate 80 side in the fixed receiving structure 91b4. can do.

  Furthermore, as an example of another method suitable for application to the cover member sealing structures 91 and 92, a mode in which the cover member sealing structures 91 and 92 are formed of resin will be described. FIG. 12 is a configuration diagram showing a configuration in which the cover member 90 and the mechanism plate 80 can be sealed with resin. In the figure, a substantially hollow resin molded portion A1 is formed in the mechanism plate side sealing portion 91b of the mechanism plate 80. Then, a substantially hollow resin molded portion A <b> 2 is formed in the cover member side sealing portion 91 a of the cover member 90. Here, an opening A11 is formed on the cover member 90 side of the resin molding portion A1, and an opening A21 is formed on the mechanism plate 80 side of the resin molding portion A2. The opening A11 and the opening A21 face each other when the cover member 90 and the mechanism plate 80 are overlapped, and allow the resin molded portion A1 and the resin molded portion A2 to communicate with each other.

Further, the resin molded portion A2 has an opening A22 facing outward. In such a configuration, the resin is injected from the opening A22. The resin injected from the opening A22 passes through the opening A21 and the opening A11 and stays in the resin molding portion A1. Then, when the resin that is successively retained fills the resin molding part A1 and the resin molding part A2, the injection of the resin is stopped. This resin has a property of curing as time elapses, and the cured resin is formed in a substantially gourd shape through the opening A11 and the opening A21 in the resin molding portion A1 and the resin molding portion A2. The The cover member 90 and the mechanism plate 80 are sealed by the resin formed in the substantially gourd shape.

  In the above-described embodiment, the opening 150 is arranged on the back side of the glass door frame 60, and when the hall operator opens the glass door frame 60 after closing the store to clean the game board 30 or the like, the opening is also opened. The cover member sealing structure 91 is visually recognized through the portion 150 so that the sealing state can be recognized. Such an opening 150 may be disposed on the back side of the glass door frame 60, or, of course, formed in the glass door frame 60, so that the cover member sealing structure 91 can be visually recognized without opening the glass door frame 60. Then, the sealed state may be recognized. The front view which looked at the glass door frame 60 in this case from the front is shown in FIG.

  In the same figure, an opening 151 is formed in the glass door frame 60 and communicates with the opening 150 formed in the game board 30, the main body frame 20, and the mechanism board 80 as necessary, so that the front surface of the pachinko gaming machine 1 is provided. So that you can see the back side. Accordingly, since the cover member sealing structure 91 can be visually recognized and the sealed state can be recognized without opening the glass door frame 60, the hole worker can open the opening during the circulation of the hole. Just look into the part 151. On the other hand, if the opening 151 is formed in the glass door frame 60 itself in this way, the decoration applied to the front surface of the pachinko gaming machine 1 may be damaged. Therefore, the inclined wall cover 151 a and the inclined wall cover 151 b shown in FIGS. 14 and 15 are fitted into the opening 151. In the figure, the inclined wall cover 151a is formed with a plurality of inclined walls 151c that are inclined from the upper direction toward the lower direction, and the inclined wall cover 151b is directed from the center direction of the pachinko gaming machine 1 toward the outer side. An inclined wall 151d is formed.

  In this way, by forming the inclined walls 151c and 151d, the inclined wall can block the view and prevent the cover member sealing structure 91 from being seen from the viewpoint of the player. On the other hand, from the viewpoint of the worker in the hall, the cover member sealing structure 91 can be made visible through the inclined walls 151c or the inclined walls 151d. As a result, the cover member sealing structure 91 can be excluded from the player's field of view. At this time, if the same decoration as that of the glass door frame 60 is provided on the outside of the inclined walls 151c and 151d, the player can be prevented from being aware of the opening 151.

(3) Configuration capable of indirectly recognizing the sealing state of the cover member sealing structure:
The embodiment described above employs a configuration in which the cover member sealing structure 91 is directly visually recognized through the opening 150 or the opening 151 and the sealing state is recognized. On the other hand, the method of recognizing the sealing state of the cover member sealing structure 91 is not limited to the method of directly viewing the cover member sealing structure 91, but indirectly covers the cover member sealing structure 91. A method for recognizing a stop state can also be taken into consideration. Thus, an example of a configuration that can indirectly recognize the sealing state of the cover member sealing structure 91 is shown in FIGS. 16 and 17. In the figure, a member composed of a tag portion 200 and a connecting member 201 is connected to a path 203 formed in the game board 30, the main body frame 20, and the mechanism board 80 as necessary. Is inserted, and the end of the connecting member 201 is fixed to the cover member 90 by the fixing portion 202.

At this time, in a state where the glass door frame 60 of the pachinko gaming machine 1 is opened, the tag portion 200 is fixed at a predetermined position of the main body frame 20. On the other hand, when the cover member sealing structures 91 and 92 are damaged and the cover member 90 is opened, the fixing portion 202 is damaged and the connecting member 201 is detached from the cover member 90. As a result, the tag part 200 hangs down, or the tag part 200 and the connecting member 201 fall. That is, the worker in the hall can indirectly recognize the sealing state of the cover member 90 through the state of the tag unit 200 and the like, and the tag unit 200 is hanging or falling. It is possible to determine that the cover member sealing structures 91 and 92 have been destroyed, the cover member 90 has been opened, and some fraud has been performed on the substrate box.

  Thus, about another example of the method which can recognize the sealing state of the cover member sealing structure 91 indirectly, the structure is shown in FIGS. In the drawing, a substantially hollow drop path 210 having a substantially square cross section is formed in the vertical direction of the main body frame 20, and a substantially tetragonal shielding member 211 capable of dropping the drop path 210 in the drop path 210. Insert. Then, the support member 212 is erected on the game board 30 side of the cover member 90, and the support member 212 is inserted into the support member insertion path 213 formed in the main body frame 20 and the game board 30 or the mechanism board 80. The shielding member 211 is supported at the end of the supporting member 212 so as not to fall. Further, the dropping path 210 is disposed so that the lower end is positioned in front of the launching rod 214, and the shielding member 211 that has fallen through the dropping path 210 is accommodated in a shielding structure 215 formed in front of the launching kit 214. Is done.

  The shielding structure 215 is formed to have a width T2 that is slightly larger than the path width T1 (approximately the diameter of the game ball) of the launch path 216, and the shielding member 211 has a width equivalent to the width T2. As described above, the shielding member 211 is accommodated in the shielding structure 215 while falling. When the shielding member 211 is accommodated in the shielding structure 215 in this manner, the game ball is not supplied in front of the launcher 214 and the game cannot be performed. That is, when the cover member sealing structures 91 and 92 are destroyed, the cover member 90 is opened, and any illegal action is performed on the board box, the shielding member 211 is accommodated in the shielding structure 215 and becomes unplayable. This makes it possible to recognize that an illegal act has been performed indirectly. By adopting such an embodiment, the pachinko gaming machine 1 in which a fraudulent act has occurred can be made impossible to play a game, which is preferable. Here, the shielding member 211 constitutes a tag portion according to the present invention, and the support member 212 constitutes a connecting member according to the present invention.

  In the above-described embodiment, as shown in FIG. 5, the cover member is opened through the opening 150 formed in the main body frame 20 so as to penetrate from the front surface to the back surface of the pachinko gaming machine 1 by opening the glass door frame 60. The sealing state of the sealing structure 91 is made visible, and the glass door frame 60 is opened for various operations, and at the same time, the sealing state of the cover member sealing structure 91 can be recognized. Here, in this embodiment, the glass door frame 60 employs a configuration in which the upper plate 63 is integrally formed. Depending on the model of the pachinko gaming machine 1, the upper plate door frame is formed separately from the glass door frame 60, is pivotally supported by the main body frame 20, and can be opened and closed with respect to the main body frame 20. is there. In such a pachinko gaming machine 1, there are many opportunities for the upper plate door frame to be opened for operations such as cleaning the upper plate 63. At this time, when the upper tray door frame is opened, a configuration in which the sealing state of the cover member sealing structure 92 on the lower left corner portion side of the cover member 90 is visually recognized may be employed.

  FIG. 21 is a perspective view of a state in which an upper plate door frame formed separately from the glass door frame 60 of the pachinko gaming machine 1 is opened. In the figure, a state in which the upper plate door frame 63a is opened is shown. When the upper plate door frame 63a is opened, the main body frame 20 that is attached to the outer frame 10 and that has a game area 31 portion opened in a substantially circular shape appears. And in this embodiment, the opening part 250 penetrated from the front surface of the pachinko gaming machine 1 to the back surface is formed in the main body frame 20 on the back surface side of the upper plate door frame 63a. The opening 250 is formed at a position facing the cover member sealing structure 92 disposed on the back surface of the pachinko gaming machine 1, and is formed in the main body frame 20, the game board 30, and the mechanism board 80 as necessary. It is comprised by the formed opening shape. Here, FIG. 23 shows an enlarged view when the opening 250 is viewed from the front.

  Thus, since the cover member sealing structure 92 is visible through the opening 250, the worker in the hole opens the upper plate door frame 63a and seals the cover member from the opening 250. By visually recognizing the stop structure 92, the sealed state can be recognized. As a result, it is possible to check fraud against the cover member 90 while visiting the hall after closing the store, opening the upper plate door frame 63a and performing various operations, and the cover member 90 that can be performed even during business. It becomes possible to detect an illegal act on the substrate box that is performed by opening the lid illegally at an early stage.

(4) Summary:
Thus, in this embodiment, since the cover member sealing structures 91 and 92 are visible through the openings 150 and 250, the worker in the hall can use the glass door frame 60 or the upper plate door. By opening the frame 63a and visually recognizing the cover member sealing structures 91 and 92 from the openings 150 and 250, the sealed state can be recognized. As a result, it is possible to check fraudulent acts on the cover member 90, that is, fraudulent acts on the board box, while visiting the hall after closing the store, opening the glass door frame 60 and performing the above-described various operations. It becomes possible to detect fraudulent acts on the board box at an early stage.
