Description

  The present invention relates to a control board storage case for a gaming machine attached to a gaming machine such as a pachinko gaming machine or a slot machine.

  On the control board of the gaming machine, a storage device ROM in which game control contents such as a jackpot occurrence probability are written is arranged. This game control content is set in accordance with legal regulations and cannot be changed without permission. However, by exchanging the storage device ROM of the control board, fraudulent acts such as making it easy to generate a big hit or increasing the number of prize balls are performed.

  In order to prevent such illegal acts, for example, in Patent Document 1, as a control board storage case for storing the control board, a plurality of mounting holes provided on one side edge of the case body and the lid body are provided. A boss portion is provided, and a plurality of flange portions are provided on one side edge of the other so as to correspond to each boss portion, and the heads of the screws to be screwed into the mounting holes are fastened in the tightening direction. A configuration has been proposed in which a pair of boss portions and a flange portion are fastened by a fastening screw that can only be screwed. In this configuration, since the fastening screw that fastens the pair of boss portions and the flange portion cannot be removed, the case body and the lid cannot be opened unless the boss portion or the flange portion is damaged. Traces remain. As a result, unauthorized opening of the control board storage case is prevented, so that an illegal act of replacing the storage device ROM of the control board cannot be performed.

  On the other hand, in Patent Document 2, as a substrate case composed of a storage part and a base part, the storage part and the base part are superposed (attached state), and the pin insertion port provided in the storage part is substantially π-shaped. A configuration has been proposed in which a pin of a mold is pushed in from the front side to engage a sealing base provided in the base portion to seal the storage portion and the base portion. Here, the peripheral edge of the pin insertion opening is provided with a wall portion that surrounds the top of the pin with the pin engaged, and it is extremely difficult to remove the pin from the storage portion side. Therefore, in order to release the sealing state described above, all or part of the wall portion provided on the peripheral edge of the pin insertion port must be cut off, and the pin must be further cut, leaving a trace of opening. Even in this configuration, fraudulent acts can be prevented in the same manner as described above.

Japanese Patent No. 3261484 JP 2006-247411 A (see “Best Mode for Carrying Out the Invention”, FIGS. 7 and 8)

  However, in the configuration of the above-mentioned Patent Document 1, a method of screwing the fastening screw in a direction opposite to the tightening direction and the tool thereof are known, and the fastening is performed without damaging the boss portion and the flange portion. There has been a problem that the control board storage case is illegally opened without removing the screw and leaving a trace of opening. For this reason, it is no longer possible to reliably prevent unauthorized opening of the control board storage case with only such fastening screws.

  Moreover, in the structure of the above-mentioned patent document 2, since the substantially pi-shaped pin is pushed in from the storage portion side, the top portion of the pin is exposed to the front side, so that the surrounding wall portion is destroyed. It is possible to cut the top of the pin without it so that the pin can be removed relatively easily. Therefore, it is possible to open with almost no trace left by leaving only the pin broken and then sealing it with another pin (a pin mounted for backup). If unauthorized opening is made in this way, there is almost no trace of it, so there is also a problem that discovery of unauthorized opening is likely to be delayed, and disadvantages are likely to occur in the game hall.

  The present invention solves the above-mentioned problems and provides a control board storage case for a gaming machine that cannot be opened without leaving a trace.

  The present invention includes a case main body that houses a control board and covers the mounting surface side of the control board, and a case bottom body that is attached to the case main body so as to cover the back side of the control board. In a control board storage case for gaming machines that seals the body in its mounted state, the case main body and the case bottom body can be relatively moved only in the front-rear direction along the plate surface direction of the control board A plurality of sealing main portions provided with storage holes that are open on both front and back sides, provided on one side edge of the case bottom body, and provided on one side edge of the case main body so as to be cut and A plurality of sealed adherent portions that are paired with the respective sealed main portions, each having a ridged insertion groove that communicates with the storage holes of the respective sealed main portions in the front and back directions in the mounting state described above, and the mounting In this state, it is pushed into the storage hole of the sealing main part from the back side and locked to the sealing main part. Thus, the upper end portion is inserted into the insertion groove of the sealing adherend portion, and includes a lock piece that is positioned at a holding position that restrains the case main body and the case bottom body so as not to move forward and backward. This is a control board storage case for a gaming machine.

  In such a configuration, with the case main body and the case bottom body in the mounted state, the lock piece pushed into the storage hole of the main sealing portion is positioned at the holding position, so that the lock piece becomes the storage hole and the storage hole. Is inserted into the insertion groove of the sealing adherence portion that communicates with the inner surface of the sealing body, so that a so-called wrinkle effect is generated. It is what I did. And since the lock piece made into the holding position is held inside the storage hole and the insertion groove and covered with the sealing main part and the sealing adherend part, the locked state with the sealing main part It is practically impossible to release the lock or to release the lock piece only by cutting it. Therefore, in order to release this sealed state and allow the case main body and the case bottom body to be opened, the sealing adherend must be cut from the case main body. Therefore, when the control board storage case is opened after being sealed, the seal adherent portion is surely damaged, so that a trace remains. Therefore, the control board storage case can be prevented from being illegally opened and temporarily opened. Even in such a case, since the trace can be found relatively easily, it is possible to suppress as much as possible the disadvantage suffered by the game hall due to unauthorized opening.

  In this case, the control board storage case for storing the control board normally has a case bottom body that covers the back side of the control board in order to make the mounting surface of the control board visible when mounted on the gaming machine. Mounted on the machine. Therefore, when the control board storage case is attached to the gaming machine, the back side opening of the storage hole is covered with the gaming machine, so that the lock piece is completely covered from the outside, and the lock piece in the holding position Can not be damaged only. Even if it is possible to remove the control board storage case from the gaming machine and open it illegally, for example, by damaging only the lock piece from the back side of the storage hole, only time is required for the damaging action. In addition, since it takes time to remove and attach the control board storage case, it becomes easy to find an act of unauthorized opening, and as a result, the effect of preventing unauthorized opening can be enhanced.

  In the control board storage case for a gaming machine described above, the lock piece has a substantially arrow shape including an elastic locking claw portion that is inclined downward and elastically deformable inward and outward at an upper end portion thereof. The elastic locking claw portion is pushed outward from the back side into the storage hole of the sealing main portion and is expanded outward and locked to the upper opening peripheral edge of the storage hole, so that it can be positioned at the holding position. A configuration is proposed. Here, as the storage hole, at least the front side end portion is configured to extend inward so that the elastic locking claw portion is elastically deformed inward, or the hole diameter is relatively expanded. A configuration set so as to be shorter than the open length can be suitably used.

  As a lock piece having such a configuration, by pushing into the storage hole from the back side, the elastic locking claw portion can be moved to the front side while being elastically deformed inwardly, and the elastic locking claw portion is formed in the storage hole. When protruding from the front side, the elastic locking claw portion is expanded outward, locked to the periphery of the upper opening of the storage hole, and positioned at the holding position. Therefore, when the holding position is set in the mounted state, as described above, the elastic locking claw portion of the lock piece is disposed in the insertion groove and completely covered from the outside. The part cannot be elastically deformed inward, and the locked state with the periphery of the upper hole cannot be released.

  When the lock piece is in the holding position, the elastic locking claw portion forming the upper end portion is in the insertion groove, and the lower portion except the upper end portion is in the storage hole. The stop main portion and the sealing adherend can be restrained so as not to move in the front-rear direction.

  In the control board storage case for the gaming machine described above, the sealing main portion provided on the bottom of the case has a lock piece pushed into the storage hole from the back side, and the upper end protrudes from the storage hole to the front side. In order to be positioned at the temporary fixing position, a configuration is proposed in which an elastic locking claw portion of the lock piece is expanded outward and locked in the storage hole. The

  In such a configuration, for each of a plurality of sealing main portions, a dedicated locking piece for restraining the pair of sealing adherent portions can be held in a temporary fixing position in advance. It has become. Thereby, since the lock piece is prepared according to the number of times that the control board storage case can be normally opened and closed, there is no need to prepare the lock piece every time the control board storage case is opened and closed, and the lock piece is placed in another part. There is no need to arrange them. Further, at the temporary fixing position, the lock piece is locked in the storage hole by the elastic locking claw portion, so that the lock cannot be released and removed from the storage hole without being damaged. . Therefore, if the lock piece is illegally opened due to damage or the like, it is impossible to perform an act of concealing the illegal release using the lock piece locked at the temporary fixing position of another storage hole.

  Note that the lock piece locked at the temporary fixing position also has an excellent advantage that it is not dropped and lost even when the control board storage case is carried.

  In the control board storage case for the gaming machine described above, the sealing main portion provided on the case bottom body is fitted to the pair of sealing covering portions from the front, and the sealing covering portion in the mounted state. The structure which comprises the front part coating | coated part which coat | covers at least the front side of is proposed. Here, as the front covering portion, a configuration formed so as to cover the boundary between the housing hole of the sealing main portion and the insertion groove of the sealing adherend portion from the front and side is preferable. is there.

  In such a configuration, in the mounted state, the boundary between the housing hole of the sealing main portion and the insertion groove of the sealing adherend portion is covered by the front covering portion, so that the lock piece as the holding position is covered from the outside. The hiding effect is improved. Accordingly, for example, it is possible to reliably prevent an illegal act such as a thin plate or the like entering from the boundary to cut the lock piece or to deform inward. Thus, the effect of the present invention for preventing unauthorized opening is further improved.

  As described above, the control board storage case for the gaming machine of the present invention has the lock piece pushed into the storage hole from the back side in the mounted state of the case main body and the case bottom body, the upper end portion of which is the storage hole. The lock is positioned at the holding position because the case main body and the case bottom body are restrained from being moved in the front-rear direction and sealed by being positioned at the holding position inserted in the communicating insertion groove. Since the piece is covered with the sealing main part and the sealing adherent part, in order to release and release the sealing, it is necessary to cut the sealing adherent part from the case main body. And, for example, the lock cannot be opened illegally only by breaking the lock piece. For this reason, if it is opened after sealing, the opened trace (cut trace of the sealed adherent portion) remains reliably, so that the control board storage case can be prevented from being illegally opened and temporarily opened. However, since it can be easily discovered, damage to the game hall can be minimized.

  In the control board storage case for a gaming machine described above, the substantially arrow-shaped lock piece having the elastic locking claw portion formed at the upper end is pushed into the storage hole, and the elastic locking claw portion expands outward. When it is positioned at the holding position by being opened and locked to the periphery of the upper opening of the storage hole, the elastic locking claw is sealed if the lock piece is set to the holding position in the mounted state. Since the elastic locking claw portion cannot be released from the holding position because it is completely covered by the adherend portion, the above-described effect of preventing unauthorized opening can be more appropriately generated.

  In the control board storage case for a gaming machine described above, the elastic locking claw portion of the lock piece is expanded outwardly and engaged with the temporary fixing engagement portion provided in the storage hole of the sealing main portion. In the case of a configuration in which the lock piece is positioned at a temporary fixing position that does not protrude outward from the storage hole by stopping, the lock piece is sealed by holding the lock piece in the temporary fixation position of each storage hole in advance. When stopping, a lock piece held in each storage hole can be used. Further, the lock piece positioned at the temporary fixing position is not lost by dropping or the like when the control board storage case is transported.

  In the case of the control board storage case for a gaming machine described above, when the sealing main part is configured to include a front covering part that covers at least the front side of the sealing adherent part in the mounted state, Since the boundary between the storage hole of the stop main portion and the insertion groove of the sealing adherend portion is covered by the front covering portion, the effect of covering the lock piece from the outside is improved. Therefore, the effect of the present invention for preventing the unauthorized opening described above is further improved.

  As shown in FIG. 1, the case bottom body 3 includes a substantially rectangular plate-like bottom surface portion 11, side wall portions 12 and 12 that stand up from two opposing long sides of the bottom surface portion 11, and a bottom surface. It is comprised from the side wall part 13 which stands up from the one short side of the part 11 to the surface. A plurality of sliding support edge portions 15 projecting inward from the upper end edge are formed on the side edge portions 12 and 12 in the longitudinal direction facing each other. In addition, fitting openings 17 and 17 are provided on both side portions of the side wall portion 13 so as to penetrate in the front-rear direction. Furthermore, a plurality of fitting protrusions 16 protruding outward along the surface direction are provided on the other short side of the bottom surface portion 11 where the side wall portion 13 is not formed. In the case bottom 3, an insertion opening 14 for inserting the case main body 2 is provided so as to face the side wall portion 13 provided on one short side and along the other short side. It is configured.

  On the other hand, the case main body 2 described above has a rectangular housing shape having a rectangular opening (not shown) closed by the bottom surface portion 11 of the case bottom body 3 on the back side, and the main surface portion 21 on the front side, The sub-surface portions 22, 23, 24 that are shorter than the main surface portion 21, the belt-like sliding side edges 25, 25 along the long sides facing each other, and the sliding side edges 25, 25 stand from the back side. It is comprised from the side wall parts 27 and 27 and the side wall parts 28 and 29 which stand up to the back along the short side which mutually opposes. The case main body 2 is formed with screw holes (not shown) at the four corners thereof, and the control board 8 is screwed and accommodated by a predetermined screw through the screw holes. Here, the control board 8 is attached to the case main body 2 so that the mounting surface 8a on which each electronic component is mounted is disposed in the case main body 2 (see FIG. 3B). Thereby, the mounting surface 8a of the control board 8 is protected while being visible from the outside. Further, an opening (not shown) is formed in the sub-surface portions 22, 23, 24 of the case main body 2 at a position facing the connector in a state where the control board 8 is attached. It is exposed to the outside. Thus, a predetermined cable can be connected to or removed from each connector in a state where the control board storage case 1 is sealed. Further, in a state where the control board 8 is attached to the case main body 2, the control board 8 is prevented from protruding to the back side from the side wall portions 27, 28, 29 of the case main body 2.

  The case main body 2 and the case bottom body 3 are formed by inserting the sliding side edges 25 and 25 of the case main body 2 between the bottom surface portion 11 and the sliding support edge 15 of the case bottom body 3, It is relatively movable in the front-rear direction (longitudinal direction) along the surface direction of the bottom surface portion 11. That is, with the side wall portion 28 of the case main body 2 as the head, the insertion is performed along the surface direction of the bottom surface portion 11 of the case bottom body 3 from the insertion opening 14 facing the side wall portion 13 of the case bottom body 3 and forward. Moving. Then, by moving the side wall portion 28 of the case main body 2 and the side wall portion 13 of the case bottom body 3 closest to each other, as shown in FIGS. 2 (A) and 3 (A), the opening portion of the case main body 2 is opened. 26 is closed by the bottom surface portion 11 of the case bottom body 3. As described above, the case main body 2 and the case bottom body 3 can be opened and closed by relatively moving (sliding) along the front-rear direction (longitudinal direction).

  Here, the case main body 2 is restrained from moving in the front-back direction by the bottom surface portion 11 of the case bottom body 3 and the sliding support edge portions 15, and is further shortened by the side wall portions 12, 12 of the case bottom body 3. Movement in a direction (a direction perpendicular to the longitudinal direction in the surface direction of the bottom surface portion 11) is restricted. Thus, the case main body 2 and the case bottom body 3 can only be moved in the longitudinal direction, and can be opened and closed by this movement. And the case bottom body 3 has a role as a lid | cover which closes the back side opening part of the case main body 2 of rectangular housing shape.

  In addition, the state (FIG. 2 (A) and FIG. 3) closed by the opening part 26 of the case main body 2 and the bottom face part 11 of the case bottom body 3 is a mounting state according to the present invention. Further, the longitudinal direction of sliding is the front-rear direction according to the present invention, and in this embodiment, the direction toward the side wall portion 13 of the case bottom body 3 is the front and the reverse direction is the rear. Here, the front-rear direction is a direction substantially orthogonal to the front and back directions described above.

  Further, in this embodiment, the side wall 28 of the case main body 2 is provided with plate-like fitting protrusions 30 and 30 protruding along the longitudinal direction on both sides of the back end thereof. In the mounted state, it is inserted into the fitting inlets 17 and 17 provided in the side wall portion 13 of the case bottom body 3. Furthermore, a plurality of fitting holes (not shown) are formed in the side wall 29 of the case main body 2 for fitting the fitting protrusions 16 of the case bottom body 3 in the mounted state.

Next, the main part of the present invention will be described.
As shown in FIG. 1, a plurality of sealing main portions 31 having storage holes 32 penetrating in the front and back direction are arranged in parallel on the side wall portion 13 of the case bottom body 3 described above. Here, in this embodiment, the two sealing main portions 31 are arranged side by side.

  The housing hole 32 of the sealing main portion 31 is formed so that the hole cross section has a substantially rectangular shape with the direction along the side wall portion 13 being long and the front-back direction being short (FIG. 4). reference). As shown in FIG. 4, the storage hole 32 is formed with inclined inner surfaces 34, 34 in which the inner surface of the short hole is gradually inclined inwardly at the upper part (front side portion). Further, temporary fixing engagement portions 33 and 33 projecting inward from the inner surfaces of the short holes are provided below the inclined inner surfaces 34 and 34.

  As shown in FIGS. 1 and 2, the sealing main portion 31 is formed with a front covering portion 36 that stands on the front side rather than the front opening of the storage hole 32 on the front side. The front covering portion 36 includes a front portion 36a covering the front surface, extended side portions 36b and 36c extending rearward from both side ends thereof, and an extended front portion 36d extending rearward from the upper end (front end). It consists of and. Further, in the two sealing main portions 31, the extended side portions 36 b that are outside each other are formed in a shape protruding rearward so as to hide the storage hole 32 from the outside. Further, the front covering portion 36 is formed with a fitting opening 39 penetrating in the front-rear direction in the front portion 36a.

  On the other hand, on the side wall portion 28 on one side of the case main body 2, two sealing adherence portions 41 that are paired with the sealing main portion 31 are provided in parallel. The sealing adherence portion 41 is connected to the side wall portion 28 via thin hook-like connection rod portions 40, 40 protruding forward from the side wall portion 28 of the case main body 2. Here, since the connecting collars 40 and 40 can be cut relatively easily with a tool such as a nipper, the sealing adherend 41 can be separated from the case main body 2 by cutting (see FIG. 5).

  The sealing adherence portion 41 is provided with a ridged insertion groove 42 that is open on the back side and closed on the front side (see FIG. 4). The insertion groove 42 is formed so as to communicate with the storage hole 32 of the paired sealing main portion 31 in the front and back direction when the case main body 2 and the case bottom body 3 are attached. Therefore, in the mounted state, the storage hole 32 of the sealing main portion 31 is completely closed from the front side by the sealing adherent portion 41. Further, the sealing adherence portion 41 is fitted into the front covering portion 36 of the sealing main portion 31 from the rear in the mounted state (see FIG. 2). In the state where the sealing adherence portion 41 and the front covering portion 36 of the sealing main portion 31 are fitted, the housing hole 32 and the sealing adherent portion of the sealing main portion 31 are formed by the front covering portion 36. The boundary with the insertion groove 42 of 41 is covered from the outside. As a result, it is impossible to allow a blade or the like to enter the boundary between the storage hole 32 and the insertion groove 42 in the mounted state. Although the front covering portion 36 does not cover the rear of the boundary, since the side wall 28 of the case main body 2 is close to the rear, the blade or the like cannot enter as described above. Similarly, although the boundary is not covered from the side between the two sealing main portions 31 (and the sealing adherence portion 41) arranged side by side, the sealing main portions 31 are close to each other. As a result, a blade or the like cannot enter.

  Further, the sealing adherence portion 41 is formed with a fitting protrusion 49 protruding forward from the front surface thereof. The fitting protrusion 49 is formed in front of the sealing covering portion 41 that forms the front covering portion 36 of the sealing main portion 31 when the case main body 2 and the case bottom body 3 are in the mounted state. It fits into the fitting opening 39 of the part covering part 36. Thereby, the position which connects the insertion groove 42 of the sealing adherence part 41 and the storage hole 32 of the sealing main part 31 in the front and back direction can be accurately positioned.

  Further, a lock piece 51 for restraining the forward and backward movement of the sealing main part 31 and the sealing adherence part 41 is held in the storage hole 32 of the sealing main part 31 described above. As shown in FIG. 4, the lock piece 51 includes a plate-like insertion bottom plate portion 52 substantially similar to the hole cross-sectional shape of the storage hole 32, a main piece portion 53 rising upward from the insertion bottom plate portion 52, and the main piece portion 53. It is composed of elastic locking claws 54, 54 that protrude upward from the piece 53, further bend outward, and incline downward. Here, the main piece portion 53 has an I-shaped cross section, and the above-described elastic locking claw portions 54 and 54 project upward from both sides thereof. The two elastic locking claws 54, 54 are formed in a shape of a thin plate, projecting upward so as to be parallel to each other, and curving outward at the upper ends thereof and inclining downward. . Each of the elastic locking claws 54, 54 can be elastically deformed inward and outward. By providing the elastic locking claw portions 54, 54 at the upper end portion, the lock piece 51 is formed in a substantially arrow shape.

  Such a lock piece 51 is pushed into the housing hole 32 of the sealing main portion 31 from the back side thereof, so that the above-described temporary locking engagement portions 33 and 33 are connected to the elastic locking claw portions 54 and 54 inward. If it is exceeded by elastically deforming, as shown in FIG. 4A, it spreads outward on the temporary fixing engagement portions 33, 33 and is locked to the temporary fixing engagement portions 33, 33. The position where the lock piece 51 is positioned by the temporary fixing engaging portions 33, 33 is the temporary fixing position (FIG. 4A) according to the present invention. Here, since the elastic latching claw portions 54 and 54 of the lock piece 51 are substantially arrow-shaped so as to incline downward (behind) as described above, they can be expanded on the temporary fixing engagement portions 33 and 33. As long as an external force that elastically deforms inward from the upper side (front side) does not act, it cannot be moved to the back side and is positioned at the temporary fixing position. Further, as described above, the storage hole 32 is configured to include the inclined inner surfaces 34, 34 at the upper portion thereof, so that the lock piece 51 positioned at the temporary fixing position is not exposed to an external force that pushes it outward. It cannot move to the direction and is held at the temporary fixing position. Thereby, the lock piece 51 temporarily fixed in the storage hole 32 of the sealing main portion 31 is not dropped even when the case bottom body 3 (and the case main body 2) is transported, and may be lost. No. Further, the upper end of the lock piece 51 is prevented from protruding above the storage hole 32 at the temporary fix position of the lock piece 51 locked to the temporary fix engaging portions 33, 33. Thereby, the lock piece 51 positioned at the temporary fixing position does not hinder the front-rear direction movement between the case main body 2 and the case bottom body 3.

  When the lock piece 51 positioned at the temporary fixing position is further pushed into the front side from the back side, the elastic locking claw portions 54 and 54 are elastically deformed inward by the inclined inner surfaces 34 and 34 of the storage hole 32, so that 4B, the elastic locking claw portions 54 and 54 expand outwardly as shown in FIG. 4B, and the holes around the upper hole periphery of the storage hole 32 are moved. Locked to the upper surface 38. Thereby, the lock piece 51 is positioned at the holding position (FIG. 4B) according to the present invention. Here, similarly to the above, the lock piece 51 cannot be moved to the back side unless an external force that elastically deforms the elastic locking claw portions 54 and 54 is applied. Further, the lock piece 51 cannot move to the front side at the holding position because the above-mentioned insertion bottom plate part 52 is prevented from moving to the front side by the temporary fixing engagement parts 33, 33. It becomes. From the above, when the lock piece 51 is pushed into the holding position, the lock piece 51 is held at the holding position.

A sealing mode by the lock piece 51 described above will be described.
With the case main body 2 and the case bottom body 3 in the mounted state, the lock piece 51 held in the temporary fixing position (see FIG. 4A) in the storage hole 32 of one sealing main portion 31 is pushed outward. . As a result, when the lock piece 51 is positioned at the holding position, the elastic locking claw portions 54 and 54 constituting the upper end portion of the lock piece 51 are connected to the sealing main portion 31 as shown in FIG. It is held in a state of being inserted into the insertion groove 42 of the pair of sealing adherends 41. In this case, since the lock piece 51 is inserted into both the storage hole 32 and the insertion groove 42, the sealing main portion 31 and the sealing adherend portion 41 cannot be moved in the front-rear direction due to the bending action. And Thereby, in order to restrain the case main body 3 provided with the sealing main part 31 and the case main body 2 provided with the sealing adherence part 41 so as not to move in the front-rear direction, it can be sealed in the mounted state. it can. Here, in the sealed state, since the elastic locking claw portions 54 and 54 of the lock piece 51 are covered with the sealing adherent portion 41 (see FIG. 2), the elastic locking claw portion as described above. An external force for inward deformation cannot be applied to 54 and 54. Therefore, only the lock piece 51 cannot be moved from the holding position, and the above-described sealed state can be reliably maintained.

  When opening after sealing with the lock piece 51 in this way, the case is cut as shown in FIG. The main body 2 and the case bottom 3 can be moved in the front-rear direction. That is, when it is normally opened after sealing, the sealing adherence portion 41 having the lock piece 51 as the holding position is separated from the case main body 2, and the case main body 2 and the case bottom body 3 are relatively moved in the front-rear direction. Release by moving. And after this opening, since the trace which the connection collar part 40 cut | disconnected remains, it has come to be surely and easily known that it was open | released by this trace. In order to open the control board storage case 1 illegally, if the connection hooks 40 and 40 are cut as described above, the traces of cutting remain even if the connection hooks 40 are closed again. I know for sure. Therefore, unauthorized opening can be prevented.

  Further, in the sealed state as described above, the lock piece 51 at the holding position is covered with the sealing main part 31 and the sealing adherence part 41 (see FIGS. 2 and 4). And since the boundary of the accommodation hole 32 of the sealing main part 31 and the insertion groove 42 of the sealing adherence part 41 is also covered with the front part coating part 36, for example, the accommodation hole 32 and the insertion groove 42 It is also impossible to create a gap at the boundary and allow a blade or a thin plate to enter from the gap. Therefore, it is substantially impossible to release the lock piece 51 from the holding position without deforming or breaking the sealing main portion 31 or the sealing adherend portion 41. Temporarily, in the case of unauthorized opening, it is necessary to cut off the sealing adherent 41 as in the above-described regular opening, or to deform or break the sealing main part 31 or the sealing adherent 41. Become. Therefore, even in the case of unauthorized opening, the opened trace is surely left, so that unauthorized opening can be prevented.

  In addition, if it is from the back side of the storage hole 32 in the sealed state, it is possible to apply a direct action to the lock piece 51 from the outside. However, since the back side of the storage hole 32 is covered by the gaming machine when the case bottom body 3 is attached to the gaming machine, it acts directly from the back side of the storage hole 32 as described above. It cannot be generated. Even if the control board storage case 1 is removed from the gaming machine for unauthorized opening, in order to release the sealing by the lock piece 51, the locked state by the elastic locking claws 54, 54 is released. Therefore, the lock piece 51 must be broken. However, the lock piece 51 is elastic through the insertion hole 32, the insertion bottom plate portion 52 being fitted into the storage hole 32, and the insertion bottom plate portion 52 and the main portion 53a having an I-shaped cross section. Since the locking claws 54 are formed, it is extremely difficult to break from the back side of the storage hole 32 so that the locked state can be released. As a result, the lock piece 51 inserted into the storage hole 32 and the insertion groove 42 cannot be cut.

  On the other hand, since the control board storage case 1 of the present embodiment includes two pairs of the main sealing portion 31 and the sealing adherence portion 41, the one sealing main portion 31 and the sealing adherence portion are provided. 41 can be sealed by the lock piece 51 and sealed. Therefore, when it is normally opened after sealing, the case main body 2 and the case bottom body 3 are closed again to be in a mounted state, and then the other sealing main portion 31 and the sealing adherend portion 41 are connected to the lock piece 51. Thus, it can be similarly restrained and sealed. Therefore, even if it is normally opened once due to a failure or maintenance after being attached to the gaming machine, it can be similarly sealed again. Here, since the lock pieces 51 are held at the temporary fixing positions in the storage holes 32 of the respective sealing main portions 31 before sealing, each of the storage holes 32 is used when sealing each. The lock piece 51 temporarily fixed inside can be used. Even before the sealing, the lock piece 51 is positioned and held at the temporary fixing position as described above and does not fall even during transportation. By holding it, it can be easily sealed only by pushing it into the holding position.

  In this embodiment, the side wall 13 of the case bottom 3 has a boss 61 provided with a screw hole (not shown) between the two sealing main parts 31 as shown in FIGS. Is provided on the side wall 28 of the case main body 2 so as to correspond to the boss 61 in a mounted state, and a flange 62 for locking the head of the screw screwed into the screw hole. Is provided. Then, in a mounted state of the case main body 2 and the case bottom body 3, the flange portion 62 and the boss portion 61 are screwed together with a predetermined screw, thereby reducing a load acting on the lock piece 51 in a sealed state. I am doing so.

  In the control board storage case 1 of this embodiment, after the control board 8 is mounted on the case main body 2, the case main body 2 and the case bottom body 3 are closed to be in a mounted state, and one of the sealing main portions 31 is stored. By pushing the lock piece 51 held in the hole 32 outward and positioning the lock piece 51 at the holding position, the upper end portion of the lock piece 51 is inserted into the insertion groove 42 of the sealing adherend 41 and the sealing piece The movement of the main part 31 and the sealing adherence part 41 in the front-rear direction is restricted. Thereby, since the front-back direction movement of the case main body 2 and the case bottom body 3 is restrained, the control board storage case 1 can be sealed. After that, in the case of regular opening, the sealing adherent portion 41 constrained to the sealing main portion 31 by the lock piece 51 is separated from the case main body 2. Thereby, it can open | release by moving the case main body 2 and the case bottom body 3 to the front-back direction from a mounting state (closed state). Even after it is once opened, the case main body 2 and the case bottom body 3 are mounted, and the other sealing main part 31 and the sealing adherence part 41 are constrained by the lock piece 51 in the same manner. Can be sealed.

  When the control board storage case 1 is to be illegally opened, the sealing adherence portion 41 is cut as described above, or the sealing main portion 31 or the sealing adherence portion 41 is destroyed. Otherwise, the seal cannot be released. Therefore, even in the case of unauthorized opening, the trace remains with certainty, and this trace makes it possible to reliably and easily know that the unauthorized opening has been made, and is highly effective in preventing unauthorized opening.

  Further, the lock piece 51 in the holding position is held in a state where the upper end portions (elastic locking claw portions 54, 54) are inserted into the insertion groove 42 of the sealing adherend portion 41, and the insertion and This has the effect of making the direction immovable. Therefore, the lock piece 51 and the sealing adherence portion 41 are not directly fixed. Thereby, after separating the sealing adherend 41 from the case main body 2, it is possible to remove the seal adherent 41 from the sealing main portion 31 relatively easily. The elastic claw portions 54 and 54 of the lock piece 51 are exposed. Since the exposed elastic locking claws 54 and 54 can be elastically deformed inwardly, the elastic locking claw portions 54 and 54 can be sealed by being released from the holding position and further released from the temporary fixing position without being damaged. It can be taken out from the storage hole 32 of the main part 31. Accordingly, even if the sealing lock piece 51 is accidentally damaged when it is opened after sealing and then sealed, it was used for the previous sealing as described above. The lock piece 51 can be substituted and can be normally sealed.

  In the configuration of the present embodiment described above, two pairs of a sealing main portion and a sealing adherend portion are provided, but there are a plurality of other configurations such as three sets, four sets, and the like. It may be arranged. In addition, as the lock piece, an arrow-like elastic locking claw portion is configured to extend outward from two thin plate portions arranged in parallel, but as another configuration, one thin plate It can also be set as the structure extended to both outward from the part.

  In this invention, it is not limited to the Example mentioned above, About another structure, it can change suitably within the range of the meaning of this invention.
