Description

  The present invention relates to a holding structure for a board box mounted on a gaming machine.

  In recent years, gaming machines such as pachinko machines have been controlled by a computer, and this computer has a main board for determining whether or not to hit, a liquid crystal display, etc. in order to facilitate confirmation of compliance with laws and regulations. It is divided into substrates for each application, such as a display substrate for controlling the power supply and a power supply substrate for power supply, and is installed on the back of the gaming machine.

  These substrates are housed in a transparent substrate box so that unauthorized modification is not performed, and power supply and information exchange are performed via connectors protruding from the substrate box.

  The pachinko machine configured as described above has a problem that the substrate can be easily replaced. For example, since the main board is a board that controls the probability of winning among the boards, an illegal board that can set the probability of hitting freely with a board equivalent to the main board is prepared, and the legitimate main board and There has also been a case where an illegal main board is exchanged in a short time during business hours and illegally gains an appearance.

Accordingly, various inventions have been made for the purpose of preventing illegal acts such as exchanging the main board related to such a ball. For example, a board box in which each board is stored is engaged with and held by a rail attached to the main body of the gaming machine, and a board box that is first installed by engaging with the rail is a board that is attached later. A structure is employed that interferes with the box and cannot be removed by the substrate box that is attached first (see Patent Document 1). Therefore, by attaching a board box containing important main boards first, and then attaching a display board, etc., a plurality of other boards must be attached to reach the main board to be replaced. Since the main board must be removed, it takes a long time to replace the main board, and it is impossible to exchange the main board for a short time during business hours to prevent fraud.
Japanese Patent Laid-Open No. 2001-145761

  However, in the substrate box holding structure as described in Patent Document 1, it takes a long time to reach the main substrate, so that it is possible to prevent unauthorized replacement that requires the main substrate to be replaced in a short time. Although effective, there is a problem that it takes a long time to reach the main board even when performing proper maintenance.

  The present invention has been made in view of the above problems, and has a robustness against an illegal act such as replacing a substrate in a short time, and can have a high maintainability while also maintaining a high maintenance performance. An object is to provide a box holding structure.

Board boxes holding structure according to the present invention in order to achieve the above object, a substrate boxes electronic circuit board which performs control relating to the game is received, the board box hold, and removable from the substrate box open A box holding rail having an end at one end, and the box holding rail is supported by a base of a gaming machine main body via a moving mechanism so that the open end can be moved. .

As a result, for legitimate actions such as maintenance, moving the open end of the box holding rail to a position where it can be inserted and removed allows the board box to be easily inserted into and removed from the box holding rail, resulting in high maintenance. Can have sex.

On the other hand, for fraud, it must be moved to a position to permit insertion and removal of the substrate box, fraud deterrent effect is troublesome is exhibited. In addition, there is an operation different from the insertion / removal operation of the board box that moves the box holding rail (especially the open end) to a position where it is easy to work. This operation is conspicuous, so the electronic circuit board is replaced secretly in a short time. A sufficient deterrent effect can be achieved against fraudulent acts that are necessary.

In an environment such as legal maintenance where large movements can be tolerated, the open end of the box holding rail can be moved to a position where it can be inserted and removed , and the target board box can be easily accessed. .

Meanwhile, since the box holding rail in addition to the direction to remove the substrate box there are different operations from the insertion and removal operation of the substrate boxes to be moved to a position to permit insertion and removal of the substrate box, this operation is conspicuous, replace the substrate in a short time It is possible to deter cheating.

  Hereinafter, an embodiment of the present invention will be described by taking a pachinko machine as a gaming machine as an example.

  FIG. 1 is a perspective view showing the pachinko machine 100 according to the present embodiment with the back surface exposed. FIG. 2 is a plan view of the pachinko machine 100 from the back.

  As shown in the figure, the pachinko machine 100 includes a pachinko machine body 101 and a rectangular cylindrical outer frame 102 surrounding the outer peripheral edge. The pachinko machine main body 101 is connected to the outer frame 102 by hinge fittings 103 provided at two positions, and the pachinko machine main body 101 can be opened and closed with respect to the outer frame 102 with the hinge fitting 103 as an axis. Therefore, when the pachinko machine main body 101 is opened with respect to the outer frame 102, the back of the pachinko machine main body 101 can be exposed to the player side.

  The pachinko machine 100 further includes a substrate box 110 in which an electronic circuit board is accommodated, a pair of box holding rails 122 that hold the plurality of substrate boxes 110 in a row, and an opening of the box holding rail 122. A baffle member 130 that faces a part of the moving region of the end 121, a ball tank 104, and a tank rail 105 are provided on a mechanism plate 106 as a base fixed to the back surface of the pachinko machine main body 101.

  The electronic circuit board includes a main board for determining whether or not the player is a big hit, a payout board for paying out a prize ball based on a command from the main board, and a liquid crystal display device based on a command from the main board. There are an effect board that performs an effect display using a lamp, a lamp board that controls a decorative lamp based on a command from the main board, a power supply board, and the like.

  The baffle member 130 is fixedly protruded from the mechanism plate 106 and fixedly connected to the stationary baffle plate 131 so as to prevent the substrate box 110 from being removed from the box holding rail 122. , And a movable baffle 132 that prevents the substrate box 110 from being removed while rotating (see FIGS. 6 to 8 for details).

  The fixed baffle 131 and the movable baffle 132 are joined by a hinge. The fixed-side baffle 131 is attached to the mechanism plate 106 near the upper side of the box holding rail 122, and the movable-side baffle 132 hangs down so as to cover the upper part of the box holding rail 122 in a normal state. .

  As described above, the structure in which the baffle member 130 can be bent is such that the presence of the baffle member 130 does not become an obstacle to the installation of the pachinko machine 100 even when the depth of the island 200 to which the pachinko machine 100 is attached is not so large. It is to make it.

  Further, the movable range of the movable baffle plate 132 is from the state in which the movable baffle plate 132 hangs down until the movable baffle plate 132 rotates 90 degrees in the direction in which the movable baffle plate 132 extends. This is for effectively realizing the effect of the movable baffle member 132 as the baffle member 130. That is, when the angle formed between the fixed baffle 131 and the movable baffle 132 is greater than 180 degrees, the effect of the movable baffle member 132 that makes it impossible to insert and remove the substrate box 110 is significantly diminished.

  FIG. 3 is a perspective view showing the substrate box 110 in detail.

  As shown in the figure, the board box 110 is a transparent resin casing provided with two through holes 111 whose axes are parallel in the height direction of both sides thereof, and houses the electronic circuit board 112 therein. In addition, a connector 113 for supplying electric power to the electronic circuit board 112 housed therein and transmitting / receiving information is attached.

  A plurality of substrate boxes 110 are provided on the back surface of the pachinko machine main body 101, but the diameters, pitches, and other shapes of the through holes 111 are the same regardless of the type of the electronic circuit substrate 112 housed therein. Yes. As a result, it is possible to unify the molds and processes for molding the substrate box 110 and reduce the manufacturing cost of the substrate box 110.

  FIG. 4 is a perspective view showing the box holding means 120 including the box holding rail 122 in detail.

  As shown in the figure, the box holding means 120 includes a pair of box holding rails 122 that can be inserted through two through holes 111 provided on both sides of the substrate box 110, and the box holding rails 122 as a base. And a hinge 123 that is rotatably attached to the mechanism plate 106.

  As shown in FIG. 3, one end of the box holding rail 122 has an open end 121 into which the board box 110 can be inserted and removed. A pair of hinges 123 are attached to the other end. The box holding rail 122 is a round pipe having a diameter that can be easily inserted into the through hole 111 provided in the board box 110. The reason why the round pipe is used as the box holding rail 122 in the present embodiment is that there are abundant general-purpose products, easy to obtain, easy to process, and contributes to cost reduction.

  The hinge 123 attached to the other end of the box holding rail 122 is a moving mechanism for rotatably attaching the box holding rail 122 to the mechanism plate 106 as a base.

  Further, the hinge 123 includes a ratchet mechanism, and the box holding rail 122 can be rotated stepwise with respect to the mechanism plate 106. In addition, the hinge 123 can only rotate in the direction in which the box holding rail 122 increases in angle from 0 degrees to 90 degrees with respect to the mechanism plate 106, but once the box holding rail 122 is rotated more than 90 degrees. The ratchet mechanism is released, and the ratchet mechanism can be rotated in a direction to return to 0 degrees.

  In addition, when the box holding rail 122 is rotated, the hinge 123 generates a “click” sound that engages the ratchet gear, and also generates a friction sound when the shaft and the bearing rotate and slide. This is to notify other people that the box holding rail 122 is being rotated.

  Next, the operation of the substrate box holding structure according to this embodiment will be described.

  FIG. 5 is a perspective view showing the state of Taijima 200 installed in the pachinko hall.

  The Taijima 200 shown in the figure is a facility that is installed in a pachinko hall in an island shape with a plurality of pachinko machines 100 mounted side by side. The pachinko balls to each pachinko machine 100 are installed inside the Taijima 200. Supply and collection are carried out all at once. Then, the player plays a game toward this Taijima 200.

  As shown in the open pachinko machine 100 in the center of the figure, the pachinko machine 100 is in a state where the outer frame 102 and the Taijima 200 are joined, and the pachinko machine 100 is fixed to the Taijima 200. In addition, by releasing the pachinko machine main body 101 from the outer frame 102, the back of the pachinko machine main body 101 can be exposed to the player side.

  Therefore, when performing maintenance to replace the board box 110 that houses the main board of the pachinko machine 100 attached to the Taijima 200, the operator exposes the back surface of the pachinko machine body 101 from the Taijima 200. After that, the box holding rail 122 is operated as follows for maintenance.

  FIG. 6 is a side view of the pachinko machine body 101.

  As shown in the figure, the box holding rail 122 stands along the mechanism plate 106 in a state where the back surface of the pachinko machine body 101 is exposed from the Taijima 200. The area where the open end 121 of the box holding rail 122 is present is the area facing the fixed side baffle 131 attached to the mechanism plate 106 above the box holding rail 122. Is in a state that cannot be removed.

  Therefore, the operator needs a large operation of rotating the open end 121 of the box holding rail 122 in a direction away from the pachinko machine main body 101 for maintenance.

  FIG. 7 is a side view showing an initial state in which the box holding rail 122 is rotated.

  As shown in the figure, in the initial state in which the box holding rail 122 is rotated, the movable baffle plate 132 of the baffle member 130 attached near the upper portion of the box holding rail 122 is used to rotate the box holding rail 122. Along with the vicinity of the open end 121 of the box holding rail 122, the substrate box 110 is rotated to enlarge the area where the board box 110 cannot be inserted and removed. And since the open end 121 of the box holding rail 122 still exists in the said area | region, the board | substrate box 110 cannot be extracted from the open end 121. FIG.

  Therefore, in order to perform maintenance, an operator performs a large operation of rotating the box holding rail 122 to a position where the movable baffle 132 does not reach the box holding rail 122, that is, an area where the board box 110 can be inserted and removed. Necessary.

  Then, as shown in FIG. 8, when the rotation of the box holding rail 122 proceeds beyond a predetermined angle, the engagement is broken, and the operator can extract the board box 110 from the box holding rail 122. Therefore, the worker can perform maintenance at this stage.

  Since the box holding rail 122 can be stopped in a stepwise manner by the ratchet mechanism of the hinge 123, the operator can make a box at a desired angle (for example, the box holding rail 122 is 45 degrees with respect to the mechanism plate 106) Maintenance work can be performed on the substrate box 110 while the holding rails 122 are maintained.

  Next, the operator who has finished the maintenance needs to return the box holding rail 122 to the original standing state. However, since the hinge 123 includes the ratchet mechanism, the box holding rail 122 is returned to the original state as it is. It cannot be rotated in the direction. Therefore, after the box holding rail 122 is rotated 90 degrees or more to release the ratchet mechanism, the box holding rail 122 is returned to the original standing state.

  Here too, the operator needs a large operation to rotate the box holding rail 122 to 90 degrees or more.

  Finally, the pachinko machine body 101 is closed and the maintenance work is completed.

  If the holding structure of the board box 110 as described above is adopted, in order to extract the board box 110 from the box holding rail 122, the pachinko machine body 101 is largely opened from the stand island 200, and the box holding rail 122 is further removed. It is necessary to perform a large operation of rotating all the substrate boxes 110 held there. Therefore, if it is a legitimate maintenance act, the above-mentioned large operation can be performed twice without any problem. However, for fraudulent acts such as replacing a legitimate board box and an illegal board box during business hours. Since the two large operations are conspicuous, it is possible to exert a sufficient effect of preventing fraud.

  Further, when the box holding rail 122 is rotated, a rattling gear “click” sound or a sliding sound between the shaft and the bearing is generated. In cheating, it becomes a psychological burden on the cheating worker, and cheating can be suppressed.

  The operation until the board box 110 can be extracted is further increased by the baffle member 130, which greatly contributes to the prevention of fraud.

  Further, in this embodiment, the box holding rail 122 is attached to the mechanism plate 106 via the hinge 123 provided with the ratchet mechanism. To release the ratchet mechanism, the box holding rail 122 is rotated largely. Since it is necessary to move the box holding rail 122 once turned, a larger operation is required to return the box holding rail 122 to its original state, and it is possible to sufficiently prevent illegal acts.

  The structure of the box holding rail 122 is a structure in which the previously held board box 110 cannot be removed unless the board box 110 held later is removed, so that the important box board is held first. If this is the case, it takes time to replace the box substrate, and of course fraud can be suppressed.

  The important box substrate is a box substrate in which a main substrate that controls the hitting of the pachinko machine 100 or the like, or a box substrate in which a substrate for controlling the number of prize balls to be paid out is stored. In order to protect the main board and the like from the static electricity of the pachinko balls accumulated at the bottom of the board, the order of holding the board box 110 on the box holding rail 122 is after holding the board box 110 containing the relatively static-resistant power supply board. It is desirable to hold the substrate box 110 in which the main substrate is accommodated.

  Further, the baffle member 130 is not an essential requirement of the present invention, and a member such as the tank rail 105 already installed on the back surface of the mechanism plate 106 may also serve as the baffle member. In this case, it is necessary to install the box holding rail 122 at a position where the substrate box 110 cannot be pulled out from at least the open end 121 of the stored box holding rail 122 by the lower surface of the tank rail 105 or the like. Further, the region where the board box 110 cannot be inserted and removed depends on the shape of the tank rail 105.

  Further, the baffle member 130 does not need to be a hard plate material and does not need a width to cover the substrate box 110. For example, even when the baffle member 130 has a rod shape and interferes with a part of the substrate box 110 at the open end 121 of the box holding rail 122, the baffle member 130 functions sufficiently as the baffle member 130. Further, a soft sheet may be applied as the baffle member 130. If the depth of the Taijima 200 is sufficient, the baffle member 130 may be protruded from the mechanism plate 106 as an integral part that cannot be bent.

  Moreover, the cross-sectional shape of the box holding rail 122 is arbitrary, and may be a prism or a cylinder instead of a pipe.

  Moreover, said angle regarding rotation of the box holding rail 122 is not limited, You may employ | adopt arbitrary angles. For example, the angle for releasing the ratchet mechanism is not limited to 90 degrees or more, and any angle such as 80 degrees or more or 70 degrees or more can be adopted.

  Further, as a substrate box holding structure, not only a combination of a through hole and a columnar member, but also a member provided with a groove (for example, a dovetail groove) in the length direction as shown in FIG. A structure may be employed in which a protrusion that is slidable with respect to the groove is provided and the groove and the protrusion are engaged to hold the substrate box.

  Further, the box holding rail 122 is not only tilted with respect to the back surface of the mechanism plate 106, but may be structured so as to be pulled out parallel to the back surface of the mechanism plate 106 as shown in FIG. In the example, a moving mechanism having a so-called scissors structure is employed).

  In the present embodiment, a pachinko machine has been described as an example, but it is needless to say that the board box holding structure can be applied to slot machines and other gaming machines.

  The substrate box includes a pair of through holes extending in the insertion / removal direction and arranged side by side in a direction intersecting the insertion / removal direction, and the base can be inserted into the through holes and the pair of the through holes. A pair of the box holding rails arranged side by side corresponding to the interval between the through holes may be supported.

  Accordingly, the positional relationship between the pair of box holding rails inserted through the through holes is regulated by the arrangement interval of the pair of through holes. Therefore, even when the pair of box holding rails are supported on the base, a separate member for restricting the positional relationship is not necessary, and the substrate box can be held with a simple structure.

  In the gaming machine main body, a baffle member is arranged so as to face a part of the moving area of the open end, and when the open end is in the area where the baffle member faces, the board box can be inserted and removed from the open end. Preferably it is not acceptable.

  Thereby, the area | region which a board | substrate box cannot insert / remove can be set. For example, if an area that cannot be inserted and removed is a normal holding position, the box holding rail (especially the open end) must be moved until the area is removed. , Can increase the deterrence effect of fraud.

  The present invention can be applied to a gaming machine, and in particular to a structure in which a board box is attached to the back part of a pachinko machine or a slot machine.
