It is possible to send unauthorized data to the control board after connecting the unauthorized external connector connected to the external device intended for fraud to the board-side connector.

JP 2006-130352 A

As described above, the conventional board protection case has an exposed structure that allows anyone to operate the unlocking piece provided on the external connector connected to the board-side connector that is exposed in the board protection case. It is easy for an actor to connect an unauthorized external connector instead of a regular external connector, and as a result, unauthorized operation of the gaming machine by supplying unauthorized data to the control board is possible.
The present invention has been made in view of the above, by preventing the act of detaching the regular external connector connected to the board-side connector exposed to the board protection case side by the fraudster. It is an object of the present invention to provide a gaming machine capable of preventing an act of illegally proceeding a game by supplying unauthorized data by connecting an unauthorized external connector to a board side connector.

In order to achieve the above object, the invention according to claim 1 is directed to a substrate protection case body that supports a board-side connector provided on a control board housed therein in an exposed state, and an external device connected to the board-side connector. A gaming machine having a board protection case unit comprising: a connector cover attached to the board protection case main body to cover the connector and the harness; and the external connector detachably connected to the board side connector The external connector is provided with a lock piece that locks when connected to the board-side connector and a release piece that releases the lock state, and the connector cover has the board protection by the releasing pieces are arranged substantially in parallel in close proximity to the surface of the external connector provided when mounted to the case body from the outside over the release piece Wherein the operating blocking member for blocking the removal operation is provided.
Since the board side connector for attaching and detaching the external connector is exposed in the board protection case installed in the gaming machine, by replacing the regular external connector with the unauthorized external connector and supplying unauthorized data to the control board There is a possibility of cheating. In order to prevent such illegal acts, even if a connector cover that prevents the replacement of the external connector is attached to the board protection case, it is not perfect. The external connector could still be replaced if the latch provided on the connector was released and released.
In the present invention, the connector cover that covers the external connector is attached to the board protective case, and the operation blocking piece protruding from the connector cover covers the latch provided on the external connector. Even if a finger or jig is inserted through the gap, it cannot be released by operating the latch. For this reason, replacement of the external connector can be effectively prevented.

According to a second aspect of the present invention , the connector cover includes a narrow strip-shaped cover main body, and a cover locking portion provided on the board protection case main body side so as to protrude from the cover main body in a direction intersecting the surface direction. A cover locked portion to be locked and the operation blocking piece projecting from the cover main body are provided.
The invention according to claim 3 is characterized in that the lock piece and the release piece are an integrated latch.

Wear Procedure is another perspective view illustrating the FIG 10 (a) (b) and (c) is a rear view showing a procedure for attaching the substrate protective case equipped with the connector cover to the base member.

The substrate protection case unit 1 according to the present invention includes a substrate protection case 20 that is removably assembled to the back surface of the base member 2 that is assembled from the back side (rear side) to a gaming machine main body 70 such as a pachinko gaming machine, The connector cover 50 detachably attached to the protective case 20 and the external connector 80 detachably connected to the board side connector are schematically configured.
Furthermore, the installation structure of the substrate protection case unit according to the present invention includes the substrate protection case unit 1, the base member 2, and the substrate protection case 20 provided on the base member 2 and locked by the locking portion 3. The stopper member 5 for preventing the movement in the direction A and the movement prevention member 60 for preventing the movement of the substrate protection case 20 assembled to the base member 2 are schematically configured.
A base member 2 made of a game board 2 made of a plywood board, an acrylic board or the like is mounted in an opening 71 provided in the gaming machine main body 70. A substrate protection case 20 is detachably attached to the back surface of the base member 2. When the substrate protection case 20 is mounted on the back surface of the base member 2, the movement preventing member 60 projecting from the back surface of the base member always prevents the substrate protection case from moving in the lateral direction (detachment direction). Unless the base member 2 is detached from the gaming machine main body 70 and the engagement between the movement preventing member and the substrate protection case is released, it is difficult to remove only the substrate protection case 20 from the base member 2.
The base member 2 as an object to which the board protection case 20 is attached need not be the game board itself, but may be an electrical component support member fixed to the game board.

The substrate protection case 20 is assembled to the back surface of the base member 2 in a state in which a control board (printed board) 40 on which electronic components such as a ROM are mounted is housed inside. That is, the board protection case 20 is vertically fixed by the base 21 that is directly assembled to the base member by being locked by the locking portion 3 provided on the base member 2 and the base 21 while the control board 40 is accommodated therein. And a substrate protection case main body (hereinafter referred to as a case main body) 25 that is pivotally supported so as to be freely opened and closed. The case body 25 includes two case pieces (a lower case piece 26 and an upper case piece 30) made of transparent resin that are accommodated inside with the control board 40 interposed therebetween. Both case pieces 26 and 30 are openable and closable and are fastened and fixed by press-fitting caulking pins (not shown) into the caulking holes 26a and 30a when both case pieces are in the closed state.
The lower case piece 26 constituting the case body 25 has a pivoted support portion (hook portion) 26b attached to a pivotal support portion (shaft portion) 21a provided on the base 21, and the pivoted support portion 26b is mounted on the pivotal support portion 21a. When the is pivotally supported, the case main body 25 can be opened and closed with respect to the pedestal 21 in the vertical direction (the direction B in FIG. 4) with the upper end edge as the center of rotation.

The pedestal 21 is a connecting means for attaching the case main body 25 to the base member 2, and the case main body 25 rotates in the upward direction (A) and the downward direction (B) about the shaft support portion 21 a. Since the case body 25 containing the control board 40 is assembled with the lower case piece 26 attached to the back surface (base member 2) of a game board such as a pachinko game machine via the base 21, the back surface of the game board The electronic component mounted on the internal control board surface can be visually recognized from the side through the upper case piece 30. Further, the inside of the case body can be confirmed from the bottom surface of the transparent lower case piece 26 by rotating the case body 25 upward (ii) around the shaft support portion 21a located at the upper portion of the base 21.
However, as described later, in the present invention, the case main body 25 cannot be rotated in the opening direction with respect to the base 21 unless the base member 2 is removed from the gaming machine main body 70. This is because, in a state where the case body 25 is closed to the pedestal 21 side, a stopper member 5 and a movement prevention member 60 which will be described later become an obstacle, and movement in the case attachment direction A and the case removal direction B is prohibited.

The board protection case unit 1 according to the present invention is further characterized in that the base 21 that is locked to the base member 2, the opening 31 that exposes the board-side connector 41 so that the external connector 80 can be attached and detached, and the engaged member. A case main body 25 that includes the stop portion 22 and accommodates the control board 40, and a substrate protection case 20 (case main body 25) for covering at least a part of the external connector 80 (harness 81) connected to the board-side connector 41. A connector cover 50 attached to the housing, and a locking portion 3 for removably locking the locked portion 22 by reciprocating the substrate protection case along the case attachment / detachment path A / B (FIG. 2). The base member 2 on the gaming machine body side provided and the board protection case 20 (connector cover 50) provided on the base member 2 and locked by the locking portion 3 are connected to the case mounting direction A (capacity). -Stopper member 5 that prevents movement in the detaching direction D) and movement that prevents the substrate protection case 20 provided on the base member 2 and locked by the locking portion 3 from moving in the case detaching direction B. And a blocking member 60.
When the movement preventing member 60 is fixed to the base member by screwing, it is preferable that the screw cannot be removed from the back side using a screwdriver or the like. For example, the screw can be removed only from the front surface of the base member.
The movement blocking member 60 does not need to be fixed to the base member 2, and even if the movement blocking member fixed to another member located in front of the base member protrudes rearward from an opening provided in the base member. Good.

  Further, the movement blocking member (movement blocking portion) 60 does not have to be a dedicated member provided only to block the movement of the board protection case, and is not provided on the game board or the frame side of the gaming machine to which the game board is mounted. It may be a part or unit provided in advance, such as a game ball payout passage, a prize ball payout device, or the like. That is, when the gaming machine is assembled, a gaming board with a board protection case attached to the inside of the frame body from the front side is mounted, but various parts and units that can become the movement preventing member 60 are attached to the frame body side. Are fixedly arranged in advance. For this reason, it suffices to lay out in advance so that the parts and units that will become the movement prevention member 60 are located in the vicinity of the board protection case when the game board is mounted on the frame.

The connector cover 50 covers a plate-shaped cover body 51 having a shape and size sufficient to enclose all the external connectors 80 and a cover locking portion (locking hole) 32 provided on the board protection case side. By moving the main body 51 in the cover mounting direction C parallel to the case detaching direction B, the cover locked portion (cover engaged) whose front end protrudes in the cover mounting direction C so as to be locked by the cover locking portion 32. Stop projection) 52, a stopper projection 53 that is disposed at the end of the cover body closer to the cover detachment direction D (a direction parallel to the case mounting direction A) than the cover locked portion 52 and protrudes in the cover detachment direction D; It has. The formation position of the stopper protrusion 53 is not limited to the end portion of the cover main body, and may be any appropriate position on the cover main body.
Further, the base member 2 is provided with a stopper member 5 having a hole 5a for fitting and holding the stopper projection 53 when the board protective case 20 with the connector cover 50 mounted is locked to the locking portion 3. The movement preventing member 60 is configured so that the stopper protrusion 53 cannot be detached from the stopper member 5 by preventing the movement of the substrate protection case locked by the locking portion 3 in the case separation direction B.
The locking mechanism comprising the locking portion 3 provided on the base member 2 and the locked portion 22 provided on the substrate protection case 20 (pedestal 21) has a rectangular locking hole as shown in FIGS. The locked portion 22 made of an L-shaped protrusion is inserted into the locked portion 3 and then moved in the case attachment direction A, so that the board protection case is not moved in the case release direction B. As long as the substrate protective case can be detached from the base member, it is not possible.

As shown in FIGS. 4 and 5, the connector cover 50 having the configuration shown in FIGS. 6 and 7 includes a cover main body 51 and a cover locking portion (locking hole) 32 provided on the side of the substrate protection case. And an L-shaped cover latched portion 52 that is latched by a stopper, and a stopper projection 53 that fits into a hole 5 a provided in the stopper member 5 provided in the base member 2.
The cover locking mechanism comprising the hole-shaped cover locking portion 32 and the L-shaped projection-shaped cover locked portion 52 is fitted to the case after the cover locked portion 52 is fitted into the cover locking portion 32. By moving the connector cover 50 in the cover mounting direction C (direction parallel to the case removal direction B) opposite to the direction A, the upper case piece 30 is locked. In this locked state, the connector cover 50 can be detached from the upper case piece 30 by moving the connector cover 50 in the cover removing direction D parallel to the case mounting direction A.

The connector cover 50 has an L-shaped cover latched with a tip projecting in the cover mounting direction C so as to be locked by the cover locking portion 32 by moving the cover body 51 in the cover mounting direction C. And a stopper protrusion 53 that is disposed at the end of the cover main body closer to the cover detaching direction D than the cover locked portion 52 and whose front end protrudes in the cover detaching direction D.
The stopper protrusion 53 protruding in the direction opposite to the front end of each cover-engaged portion 52 (cover detaching direction D) is the hole 5a of the stopper member 5 when the mounting of the substrate protection case 20 to the base member 2 is completed. It is comprised so that it may fit in.

Therefore, when the board protection case is prohibited from moving in the case removal direction B by the movement blocking member 60, the stopper protrusion 53 cannot be removed from the hole 5a of the stopper member, so that the connector cover 50 is moved in the cover removal direction D. The connector cover cannot be removed from the case body 25.
Since the shaft support portion 21a provided on the pedestal 21 and the stopper protrusion 53 are different in height (not on the same axis), the case main body is centered on the shaft support portion 21a when the stopper protrusion is fitted to the stopper member 5. It is impossible to turn 25 upward (b). For this reason, the connector cover cannot be removed from the case body unless the board protection case together with the base member 2 is removed from the gaming machine body 70.
As shown in FIG. 5, when the connector cover 50 is locked to the case body 25 (upper case piece 30), the cover body 51 conceals the external connector 80 and the harness 81 connected to the board side connector 41 while holding them. Unless the connector cover 50 is removed, the regular external connector 80 cannot be removed and an unauthorized external connector cannot be connected.

FIGS. 10A, 10 </ b> B, and 10 </ b> C show a procedure for attaching the board protection case 20 in which the connector cover 50 is attached to the case body 25 to the base member 2.
When attaching the substrate protection case 20 to the base member 2, the base member 2 is detached from the gaming machine main body 70 and the movement preventing member 60 is not attached to the base member 2.
That is, first, as shown in FIG. 10A, the base member 2 is provided with the locked portion 22 provided on the base 21 constituting the substrate protection case 20 without the movement preventing member 60 being disposed on the base member 2. After being inserted into the part 3, it is moved in the case mounting direction A to complete the locking. At this time, the stopper protrusion 53 of the connector cover 50 is held by the stopper member 5 on the base member side ((b)).
After completing the positioning of the substrate protection case 20 to the set position in this way, the substrate protection case on the base member 2 is secured by fixing (projecting) the movement prevention member 60 to the movement prevention member installation location 60a indicated by the broken line. 20 is completed ((b)). In this state, since the board protection case 20 is restricted from moving in the case removal direction B, only the connector cover whose movement is restricted by the stopper member 5 is moved in the cover removal direction D to be removed from the case body 25. It becomes impossible. For this reason, it is impossible to remove the external connector 80 connected to the board-side connector 41 and replace it with an unauthorized external connector.
When removing the board protection case from the base member, first, the base member 2 holding the board protection case is removed from the gaming machine main body 70 so that the movement preventing member 60 can be removed from the base member 2. (C) shows a state in which the movement blocking member is removed. In this state, the board protection case can be moved in the case detaching direction B, so that the connector cover 50 is detached from the case main body 25. Is also possible.

As described above, in the present invention, in the state where the substrate protection case 20 is attached to the base member 2 (the state where the substrate protection case and the base member are close to each other), the substrate protection case (case body 25) is moved in the case separation direction B. The stopper protrusion 53 provided on the connector cover cannot be detached from the stopper member 5 unless it is moved to the position, and the movement preventing member 60 further moves the substrate protection case 20 (case body 25) in the case removal direction B. Since it was configured to prevent this, an unauthorized person cannot remove the connector cover unless the base member 2 is detached from the gaming machine main body 70.
Even when the base member 2 is not detached from the gaming machine main body 70, the case main body 25 is temporarily moved upward (ii) around the shaft support portion 21a to be separated from the base 21 (movement preventing member 60). If it can be made, it becomes possible to move the case main body 25 in the case detachment direction B along the shaft support portion 21a to separate the substrate protection case 20 from the base member. Therefore, the connector cover stopper protrusion 53 can be detached from the hole 5a of the stopper member, and the connector cover can be detached from the case body. However, in the present embodiment, when the board protective case 20 is set on the base member 2, the stopper protrusion 53 of the connector cover is continuously held by the stopper member 5 on the base member side. Prevents the case body 25 from rotating in the opening direction. Therefore, it is impossible to remove the connector cover.
In addition, when an illegal act of replacing the regular external connector with an unauthorized external connector is performed during the operation of the game hall, only a little time can be spent for the illegal activity, so the connector cover is removed as in this embodiment. It is possible to effectively prevent fraud by providing an obstacle for the purpose.
In the above embodiment, the case mounting / removal direction is the horizontal direction, but it is needless to say that the vertical direction, the diagonal direction, and other directions may be used.

Next, an example of a configuration for preventing the act of illegally unlocking the external connector will be described with reference to FIGS. 11 to 14. 11 (a), 11 (b) and 11 (c) are a front perspective view of a substrate protection case to which the present invention is applied, a perspective view of a connector portion viewed from below, and a side view illustrating a procedure for attaching / detaching an external connector. 12 is a perspective view showing a state immediately before the connector cover is attached, and FIGS. 13A and 13B are side views showing the state before and after the connector cover is attached, and FIG. (B) And (c) is a perspective view which shows the state which a release piece covers a release piece with mounting | wearing of a connector cover.
As shown in FIGS. 11B and 11C, the external connector 80 is locked on the lower surface (surface opposite to the direction in which the harness 81 extends) to lock the external connector while being connected to the board-side connector 41. A lock piece 85 having a stop portion 85a and a release piece 86 for releasing the locked state are provided. The lock piece 85 and the release piece 86 constitute a connector latch (claw) 87. The locking piece 85 has a function of preventing the external connector 80 from being detached by engaging the locking portion 85a with a part of the board-side connector 41 (the locked portion), and is connected to the locking piece 85. The release piece 86 has a function of pressing this toward the external connector main body side to release the lock by separating the lock piece 85 from the locked portion of the board side connector in a seesaw manner (FIG. 11C). For example, the entire latch 87 is made of an elastic material, and the lock piece 85 is normally elastically biased so as to engage with the locked portion of the board-side connector 41 while the release piece 86 is pressed. The lock piece is configured to be disengaged. (C) By releasing the locking of the lock piece 85 as shown in the upper diagram, the external connector and the harness become detachable from the board side connector 41, and are pulled out in the direction of the arrow as in the lower part of (c). Withdrawn by.

Since the external connector release piece 86 is always exposed in the gap between the connector cover main body 51 and the case main body 25 (the upper case piece 30), the connector cover 50 is used to connect the external connector 80 and the harness 81 to each other. Even if pressed, it is possible to insert a finger or a jig through a gap formed between the cover main body 51 and the upper case piece 20 and press the release piece 86 to release the external connector.
That is, even if the external connector 80 and the harness 81 are pressed using the connector cover 50, it is sufficiently assumed that the external connector can be detached from the board side connector due to an accuracy error or an assembly error between components. The Also, it is possible to perform unauthorized actions such as connecting an unauthorized external connector after operating the release piece while pushing the gap between the connector cover body and the upper case piece using a jig and operating the release piece. There is also sex.
In short, since it is assumed that the prevention of fraud is not sufficient only by pressing the external connector with the connector cover, it is necessary to prevent the external connector from being attached or detached by a further protective means.

In order to eliminate the illegal acts as described above, the substrate protection case unit of the present invention has the following configuration.
That is, the substrate protection case unit 1 of the present invention is connected to the substrate protection case main body 25 having the opening 31 for exposing the substrate side connector 41 provided on the control substrate 40 accommodated therein, and the substrate side connector 41. The external connector 80 includes a connector cover 50 that is attached to the board protection case body to cover the external connector 80 and the harness 81, and an external connector 80 that is detachably connected to the board-side connector. A lock piece 85 that locks in a state where it is connected to the board-side connector 41 and a release piece 86 that releases the lock state are provided, and the connector cover 50 is released when it is attached to the board protection case body 25. An operation blocking piece 55 is provided to cover the piece 86 and prevent a release operation from the outside.

As shown in FIGS. 6 and 7, the connector cover 50 is provided on the side of the substrate protection case body so as to protrude from the cover body 51 in a direction intersecting (orthogonal to) the surface direction. The cover locking portion 52 and the cover locked portion 52 to be locked are provided, and further, a rib-shaped operation blocking piece 55 protruding from the cover main body 51 is provided.
The operation blocking piece 55 protrudes from the cover body so as to cover the lower surface (latch 87) of the external connector 80 connected to the board-side connector 41 when the connector cover 50 is attached to the case body 25. Since the plate-like operation blocking piece 55 protrudes substantially in parallel with the lower surface of the external connector 80 and covers the latch 87 in the state of being close to the latch 87, FIGS. 13 (b), 14 (b) and (c). It becomes impossible to release the lock by inserting a finger and operating the latch 87 as shown in FIG. Further, even if the distance between the cover main body and the case main body 25 is increased by deforming the cover main body 51 using a jig, the operation blocking piece 55 having a sufficient protruding length continues to cover the latch 87. Unlocking operation by is impossible.
The configuration for prohibiting the unlocking operation of the external connector by the operation blocking piece 55 according to the present invention can also be applied to other connector covers having structures other than the connector cover 51 shown in the above embodiment.

  As described above, in the board protection case unit installation structure of the present invention, the base member that locks the board protection case, the movement prevention member that restricts the movement of the board protection case, and the detachment of the connector cover on the board protection case Since the stopper member is provided to prevent the base member from being removed from the gaming machine main body, it is impossible to perform the act of removing the connector cover and replacing it with an unauthorized external connector. In other words, a fraudulent person removes a legitimate external connector that is connected to the board-side connector that is exposed on the board protection case side and connects the fraudulent external connector to the board-side connector to supply illegal data. Thus, it is possible to prevent an act of illegally progressing the game.

Further, in the board protection case unit according to the present invention, the external connector 80 connected to the board-side connector 41 on the board protection case side is not only covered with the connector cover 50 but also unlocked provided on the external connector. Since the piece 86 is covered with the operation blocking piece 55 provided on the connector cover so that the release operation cannot be performed, it is impossible to perform an act of replacing the unauthorized external connector unless the connector cover is removed. In other words, a fraudulent person removes a legitimate external connector that is connected to the board-side connector that is exposed on the board protection case side and connects the fraudulent external connector to the board-side connector to supply illegal data. Thus, it is possible to prevent an act of illegally progressing the game.
The combined use of the external connector attachment / detachment prevention function by the connector cover and the release piece operation prevention function by the operation prevention piece makes it possible to effectively prevent an illegal act after the external connector is detached.
The board protection case according to the present invention can be used as a means for accommodating a control board provided in a gaming machine such as a pachinko gaming machine or a slot machine.
