Description

  The present invention relates to a board case and a board mounting device for safely mounting a control board in a machine in a game machine such as a revolving game machine or a pachinko machine called a pachislot machine.

  In recent years, not only pachinko machines but also pachinko machines called pachislot machines have been actively used in conventional pachinko halls and pachislot halls. In these gaming machines, the winning probability is governed by the information in the ROM mounted on the control main board. For this reason, ensuring the security for the main board for control is a serious technical issue regardless of the model.

  In other words, in this type of gaming machine, the front of the device is opened and closed by the front door because the inside of the device needs to be frequently operated. Become. For this reason, in order to deal with the illegal actions such as remodeling of the main board for control (replacement of ROM, etc.) continuously, the mounting apparatus for the main board for control has various measures for preventing unauthorized modification. Ingenuity is taken.

  A typical board mounting apparatus that has been devised to prevent unauthorized modification includes, for example, a relatively thin board case that accommodates a main board, and a board case that is attached to a gaming machine as described in Patent Document 1. It consists of a case holder for mounting on the back plate surface of the cabinet.

  The board case has a rectangular shallow case body that holds the rectangular main board inside, and a rectangular cover for closing the front opening of the case body so that the inner main board can be seen from all directions. Both are formed of a transparent resin. The cover is fixed to the case body in a non-removable manner by a rotation engaging portion on the lower side and a plurality of caulking pins attached to both side portions on the upper side.

  The case holder is made of a rectangular resin plate corresponding to the substrate case, and is detachably attached to the surface of the back plate of the cabinet by a fixing pin, while the substrate case is detachably held on the front side. Specifically, the substrate case is detachably fixed to the case holder by a plurality of engaging protrusions provided on the lower side portion of the case holder and a plurality of caulking pins held at the center portion of the upper side of the substrate case.

JP 2007-301126 A

  According to such a substrate mounting apparatus, the substrate case cannot be removed from the case holder and the substrate case cannot be opened unless the caulking seal portion by the caulking pin is broken with a tool such as a nipper. And when the caulking seal part is destroyed with a tool such as a nipper, the trace remains clearly, and the trace can be found immediately when the game machine is opened. In addition, the surface of the internal main substrate can be directly monitored through a transparent substrate case. As a result of these, fraudulent acts such as opening the substrate case to work on the main substrate or replacing the main substrate with the substrate case are effectively prevented.

  However, fraudulent tricks have become more sophisticated year after year, and have become bolder, and things such as forcing open the caulking seal side of the board case have begun. In that case, in the conventional caulking seal portion, the caulking pin may be deformed before the substrate case is broken, and the case may be opened unexpectedly. If the case is opened illegally in this way, there is almost no trace of unauthorized opening, and deformation of the caulking pin is difficult to understand.

  The reason why the caulking seal portion with caulking pins exposes weak points to a large external force is considered as follows. Due to the characteristics of the caulking pin, the pin is arranged parallel to the opening direction of the case. As the material, when the substrate case is locked with the caulking pin, it is necessary to use a resin that is flexible to some extent because of the use of deformation of the caulking pin. For this reason, when a large external force in the opening direction is applied to the caulking seal part, it opens unexpectedly and there is almost no trace of it.

  Another problem with the caulking seal is the destruction of the caulking pin. That is, in the conventional caulking sealing part, the case is sealed by forcibly pushing the caulking pin into the pin hole from the front side after closing the substrate case. In such a caulking seal part, since the rear end of the caulking pin is exposed to the front side, only the caulking pin is destroyed and the case may be illegally opened. In this case, no trace of unauthorized opening remains in the case. This act is a problem not only in the caulking seal part of the board case, but also in the caulking seal part for fixing the board case to the case holder. The board case is illegally removed from the case holder. The case is destroyed from the side and the back side of the board is tampered with.

  The object of the present invention is to prevent the pin member from being opened without being damaged even when a large external force in the opening direction is applied to the case sealing portion by the pin member, and to prevent the pin member from being destroyed from the outside. An object of the present invention is to provide a high-security board case.

  Another object of the present invention is to provide a highly secure substrate mounting apparatus capable of preventing an external destructive action on a pin member for fixing a substrate case enclosing a substrate to a case holder.

In order to achieve the above object, the board case of the present invention is a rectangular board case that encloses a control board for a gaming machine inside, and the board case has a rectangular back plate and a square frame shape around it. and a side wall of the case body the front face facing the back plate is a front opening which opening is formed, to seal the front opening of the case body in a rectangular box shape corresponding to the case body board case And a cover that encloses the control board, and a case main body protruding portion that protrudes in a convex shape for fixing to the cover at both ends of one specific side wall of the square frame-shaped side walls around the case main body. A unit holding portion for holding the lock pin unit is integrally provided on the front side of the case main body protruding portion, and the cover is integrated with an edge portion of the case main body on the side facing the specific side wall. Hook provided Together with tiltably case body engages as a rotation fulcrum, the position corresponding to the case body protrusion a side opposite to the turning fulcrum side, the first pin operation section for operating the locking pin unit The cover is fixed to the case body so that it cannot be opened by providing both sides of the cover that are formed on both sides, and the lock pin unit is built in the unit holding part in a direction that intersects the opening and closing direction of the cover. The lock pin is held in the pin holder so as to be able to advance and retract, and the lock pin is urged from the pin holder in the advancing direction, and the taper portion provided in the first pin operation portion closes the cover. Along with this, the lock pin is pushed into the pin holder, and the lock pin protrudes and fits into the fitting part provided on the back side of the taper part. The pin holder is disposed opposite to both side portions of the case body protruding portion, and a fixing portion for fixing the substrate case to the case holder is provided between the pin holder and the fixing portion is The board case is provided between the cover both sides, and is fixed to the case holder through a notch formed between the pair of pin holders arranged opposite to each other and formed in the case body.

  In the substrate case of the present invention, a lock pin unit is used for sealing the case body and the cover. The lock pin unit is configured such that the lock pin is accommodated in the pin holder so as to be able to advance and retract, and the lock pin is urged from the pin holder in the advancing direction, and is provided on the open side of either the case body or the cover. It is built-in and held at the edge in a direction crossing the opening / closing direction of the cover, preferably in a direction perpendicular thereto. Then, by closing the cover, the lock pin in the first pin operation part is pushed into the holder against the urging force, and the cover protrudes again with the cover completely closed to lock the cover. Secure in the closed position.

  Here, the lock pin is a slide type, and is preliminarily incorporated in the case and is not inserted from the outside of the case. Therefore, the lock pin is not exposed outside the case after being locked. For this reason, it is difficult to craft the lock pin from the outside of the case, as compared with a sealing portion using a conventional deformable lock pin. In addition, the lock pin is arranged in a direction intersecting with the opening direction of the cover, preferably in a direction perpendicular to the cover, and is a slide type, so that it can be formed of a hard resin that is difficult to deform. For this reason, even if a large external force in the opening direction is applied to the cover, the cover does not open due to the deformation of the lock pin. In order to open the cover locked in the closed state, the peripheral portion of the lock pin of the cover must be destroyed and the lock pin must be forced into the holder, and the trace remains clearly in the case.

  The pin holder in the lock pin unit is arranged opposite to both sides of the open side edge of the case body, and a fixing part for fixing the substrate case to the case holder is provided between them when external force is applied. This is effective in preventing the cover from being opened. Here, a plurality of fixing portions are provided along the open side edge portion of the cover, preferably along the side edge thereof, and are provided between a pair of pin holders disposed opposite to both side portions of the open side edge portion of the case body. A configuration in which the case is fixed to the case holder through the notch is preferable.

  This is because the substrate case after the control substrate is sealed is not opened in principle. On the other hand, the substrate case is removed from the case holder several times in order to confirm the state of the back surface of the substrate during the substrate inspection by the police or the like. At this time, destroy the fixed part of the case. If a plurality of fixing parts are provided along the side edge on the open side edge of the cover, it is easy to intentionally destroy the fixing part, and the same substrate case and case holder can be used to remove and re-use multiple times. Can be installed.

The board mounting device of the present invention includes a board case that encloses a control board for a gaming machine inside, and a case holder that is fixed to the inner surface of the gaming machine in order to fit and fix the board case in the gaming machine. The board mounting device is a combination of the above, and after the board case is fitted in the case holder, it is configured to be slidable in the direction along the surface of the case in the case and cannot be separated from the case holder in the slid state. A lock pin unit in which a lock pin is accommodated in a pin holder so that the lock pin can be advanced and retracted on either one of the opposing surfaces of the substrate case and the case holder, and the lock pin is urged in the advancing direction from the pin holder. , A pin unit holding part is provided for holding toward the other facing surface side, and the substrate case is placed in the case holder on the other facing surface side. Push the lock pin into the pin holder in a combined state, a configuration in which the second pin operating portion for fixing the substrate case to the sliding position by projecting the lock pin in a state of being slid from the fitted state is provided.
In the substrate mounting apparatus of the present invention, the substrate case includes a case main body whose front surface is open, and a cover that encloses the front opening of the case main body and encloses the control substrate in the case. The case body can be engaged with a specific edge portion of the case body so that the edge portion can be tilted as a pivot point, and the case body cannot be opened by a lock mechanism provided on the edge portion on the open side opposite to the fulcrum side. The locking mechanism is built-in and held in the opening side edge of either the case body or the cover in a direction crossing the opening and closing direction of the cover, and the lock pin is accommodated in the pin holder so as to be able to advance and retract. At the same time, the lock pin unit with the lock pin urged in the advancing direction from the pin holder and the taper portion provided at the edge of the open side of the other member are locked together with the closing operation of the cover. The first pin operation part that locks the edge on the open side of the cover in a closed state by the lock pin protruding and fitting into the fitting part provided on the back side of the taper part. It is the structure which has.

  In the substrate mounting apparatus of the present invention, the substrate case is configured to be slidable in the case holder, and the lock pin unit is directed to one of the opposing surfaces of the substrate case and the case holder toward the other opposing surface. A second pin operation section is provided on the other facing surface side to operate the lock pin as the board case is fitted and slid. After the substrate case is fitted in the holder, it is locked to the holder by sliding. At this time, in the lock pin unit, the lock pin is pushed into the pin holder by the second pin operation portion. When the substrate case slides from this state, the lock pin protrudes to lock the substrate case in the slide position. Thereby, the substrate case is completely fixed to the case holder.

  The lock pin for fixing the substrate case to the case holder is a slide type, and is previously incorporated in the substrate case and the case holder and is not inserted from the outside. For this reason, compared with the sealing part by the conventional deformation | transformation type lock pin, it is difficult to work a lock pin from the outside. Moreover, since the lock pin is a slide type, it can be formed of a hard resin that is difficult to deform. For this reason, even if a sliding force toward the separation side is applied to the substrate case, sliding due to deformation of the lock pin does not occur. For this reason, the substrate case once fixed to the case holder is not detached unless the periphery of the second pin operation portion is broken and the lock pin is forcibly pushed into the holder. If this is done as a fraudulent act, the trace will definitely remain in the substrate case or case holder.

  The substrate case of the present invention uses a slide-biased lock pin for sealing the case body and the cover, and the lock pin is arranged in a direction crossing the cover opening direction, and the first pin operation portion Since it is operated along with the closing operation of the cover and is fixed in the closed state, first, the sealing operation of the cover is easy. Secondly, since the lock pin is built in the case, unauthorized opening of the case by crafting the lock pin from the outside can be effectively prevented. Third, even if a large external force in the opening direction is applied to the cover, the case can be prevented from being opened due to deformation of the lock pin. Therefore, it is extremely difficult to tamper with the control board in the case, and in the unlikely event that the tampering is performed, a clear trace remains in the case, dramatically increasing the security level against tampering of the control board in the case. Can be increased.

  Further, the substrate mounting apparatus of the present invention is configured such that the substrate case is slidable in the case holder, and the lock pin unit is directed to one of the opposing surfaces of the substrate case and the case holder toward the other opposing surface. The substrate case is fixed in a slid state by a second pin operation portion provided on the other facing surface side, so that the substrate case cannot be detached from the case holder. Since the lock pin is built in the board case and case holder, it is possible to effectively prevent unauthorized removal of the board case by crafting the lock pin from the outside. Since the trace remains clearly in the substrate case and the case holder, it is possible to effectively prevent fraudulent acts on the control substrate from the back surface of the substrate case.

In addition to having a hole 27B, the distal end portion has a tapered portion 28B that is inclined outward toward the distal end side. The taper portion 28B pushes the lock pin 41 of the lock pin unit 40 held by the holding portion 24A and guides it to the through hole 27B in accordance with the closing operation of the substrate case 20 (see FIG. 8).

  In order to prevent unauthorized operation of the lock pin unit 40 with respect to the lock pin 41 in a state where the substrate case 20 is closed, the first pin operation portion 22B is completely surrounded by the box-shaped protruding portion 21B and is isolated from the outside. It is combined with a protective plate 29B provided outside the claw portion 26B. The protection plate 29B protrudes from the front side to the back side of the cover 20B, and makes it difficult to perform an unauthorized operation to the lock pin 41 from the outside due to the destruction of the cover 20B.

  As shown in FIGS. 1 to 3, the case holder 30 that constitutes the substrate mounting device together with the substrate case 20 is a rectangular outer shape that fits from the front side and is a thin outer box that is open at the front. The board case 20 fitted into the board 30 is configured to slide downward (see FIG. 9). The back plate portion of the case holder 30 is provided with a screw hole 31 for fixing the holder to the inner surface of the gaming machine. In addition, on both sides of the lower end portion, overhang portions 36 and 36 with screw holes are provided for fixing the game machine to the inner surface of the equipment.

  At the uppermost part of the back plate, two types of hooks 32 and 33 are provided for locking the substrate case 20 as the substrate case 20 fitted in the holder 30 slides downward. The two types of hooks 32 and 33 protrude from the back plate of the case holder 30 to the front side, and the tip end portion is bent upward in a bowl shape. As shown in FIGS. 9 and 10A, the first hook 32 is located inside the protrusions 23A, 23A and 21B, 21B on both sides of the case body 20A, and the case holder 30 of the substrate case 20 is provided. Is inserted into the vertical slit provided inside the protrusions 21B and 21B of the cover 20B, and is engaged with the upper part of the vertical slit of the cover 20B as the substrate case 20 slides downward. The substrate case 20 is fixed. The second hook 33 is located on the back side of the protrusions 23A and 23A on both sides of the case main body 20A, and as shown in FIG. The case main body 20A of the substrate case 20 is fixed by fitting into the horizontal slits 29A and 29A provided on the upper surface of 23A.

  A plurality of third hooks 34 are provided side by side at the bottom of the case holder 30. The first hook 32 and the second hook 33 fix the upper part of the substrate case 20, whereas the third hook 34 is the lowermost part of the substrate case 20 on the same principle as the first hook 32 and the second hook 33. To fix.

  A plurality of pin unit holding portions 35, 35... Are provided on the uppermost portion of the back plate of the case holder 30. The plurality of pin unit holding portions 35, 35,... Are provided side by side between the first hooks 32, 32 on both sides corresponding to the fixing portion 23B (second pin operation portion 24B) of the substrate case 20. It has been. Each holding portion 35 is a cylindrical body protruding from the back plate of the case holder 30 to the front side, and holds the lock pin unit 40 so as to be detachable toward the front side.

  Since the notch 25A is provided on the upper edge of the case body 20A of the substrate case 20, when the substrate case 20 is fitted to the case holder 30, the plurality of pin unit holding portions 35, 35,. It does not interfere with the upper edge of the case body 20A of the substrate case 20. Accordingly, the lock pin unit 40 held by the holding unit 35 is operated by the second pin operation unit 24B formed on the back side of the fixing unit 23B of the cover 20B of the substrate case 20.

  Specifically, the second pin operation portion 24B provided on the back side of the cover 20B of the substrate case 20 fits the substrate case 20 to the case holder 30 as shown in FIGS. In this state, the lock pin 41 is pushed into the pin holder 42 below the cylindrical fixing portion 23B, and the substrate case 20 can be slid downward. In a state where the substrate case 20 slides downward and is fixed to the case holder 30, the lock pin 41 is fitted into the cylindrical fixing portion 23B. As a result, the substrate case 20 is prevented from sliding upward and is fixed at the lower locking position.

  Next, the usage method and function of the substrate case 20 and the substrate mounting apparatus of this embodiment will be described.

  First, the substrate 10 is fixed in the substrate housing portion 21A of the case body 20A of the substrate case 20. Further, the lock pin units 40, 40 are set inward in the holding portions 24A, 24A on both sides of the upper edge portion. When the above preparation is completed, the cover 20B is attached to the case main body 20A as shown in FIG. Specifically, the hook portions 22A and 22A formed on the lower edge portion of the case main body 20A are engaged with the corresponding hook portions of the cover 20B, and the two are hinge-coupled. In this state, an external force in the closing direction is applied to the upper edge side that is the open side of the cover 20B. Then, at the upper edge portion, as shown in FIGS. 8A to 8C, in the lock pin units 40 and 40 held by the cover 20B, the first pin operation portion 22B of the cover 20B, particularly the claw portion 26B. The lock pin 41 is pushed into the pin holder 42 by the taper portion 28B, and the cover 20B is closed. When the cover 20B is completely closed, the lock pin 41 is inserted into the through hole 27B of the claw portion 26B, and the cover 20B is fixed in the closed state.

  For convenience of illustration, in FIG. 5, the substrate 10 in the case body 20 </ b> A is not shown and is omitted.

  Thus, when the substrate 10 is completely sealed in the substrate case 20, the substrate case 20 is fixed to the case holder 30 fixed to the vertical inner surface of the device. This is done in the following procedure.

  As shown in FIGS. 2 and 3, the lock pin unit 40 is inserted and set in one of a plurality of holding portions 35, 35,. In this state, as shown in FIGS. 9A and 9B, the substrate case 20 is inserted into the case holder 30 and slid downward. By sliding the substrate case 20 downward in the case holder 30, the substrate case 20 is moved to the upper edge portion by the first hooks 32 and 32 and the second hooks 33 and 33 provided on the upper edge portion of the case holder 30. Is fixed to the case holder 30, and the lower edge portion is fixed to the case holder 30 by the third hooks 34, 34 provided on the lower edge portion of the case holder 30. “Fixed” means that the substrate case 20 is not detached from the case holder 30 to the front side.

  In addition, when the substrate case 20 slides downward in the case holder 30, as shown in FIGS. 11A and 11B, the lock pin 41 of the lock pin unit 40 held by the case holder 30 is moved to the cover 20B. The second pin operation portion 24B provided on the back surface of the lens enters the cylindrical fixing portion 23B from the state where it is pushed into the pin holder 42. As a result, the substrate case 20 is prevented from sliding upward, and the substrate case 20 is completely fixed to the case holder 30.

  In the substrate case 20 in which the substrate 10 is enclosed, the lock pin 41 and the pin holder 42 are slidable and do not need to be deformed, and therefore can be formed of a hard resin. Moreover, the lock pin 41 faces in a direction perpendicular to the opening direction of the cover 20B. For this reason, even if a large external force in the opening direction is applied to the cover 20B, a situation in which the lock pin 41 is deformed and the cover 20B opens is avoided. The lock pin unit 40 is completely enclosed in the upper edge portion of the substrate case 20. For this reason, the lock pin unit 40 cannot be destroyed from the outside.

  That is, once the substrate 10 is sealed in the substrate case 20, it is impossible to open the substrate case 20 in the vicinity of the lock pin units 40, 40 unless the substrate case 20 is largely destroyed. When the substrate case 20 is largely destroyed, the trace remains clearly on the substrate case 20. Further, since the front side of the lock pin unit 40 (outside the claw portion 26B) is reinforced by the protective plate 29B, it is more difficult to break the substrate case 20 such as operating the lock pin 41.

  Similarly, since the lock pin unit 40 enclosed in the both is used for fixing the substrate case 20 and the case holder 30, the lock pin 41 of the lock case 41 without breaking the substrate case 20 and the case holder 30 is used. Destruction from the outside is impossible. That is, also at this time, traces of destruction remain clearly in the substrate case 20 and the case holder 30.

  On the other hand, the inspection by the police or the like is performed on the board 10 attached in the device at the time of manufacturing the gaming machine at a later date. At this time, it is necessary to intentionally remove the substrate case 20 from the case holder 30 in order to check the back surface of the substrate 10 from the back surface side of the substrate case 20. At that time, the distal end blocking portion of the cylindrical fixing portion 23B is excised. Then, the lock pin 41 can be pushed in, and the substrate case 20 can be slid upward. And if this slide is performed, the substrate case 20 can be easily removed from the case holder 30.

  After the inspection, when the substrate case 20 is set again in the case holder 30, the lock pin unit 40 is placed on the front side in another one of the plurality of holding portions 35, 35. Set up and do the same. In the present embodiment, since four sets of the holding portion 35 and the second pin operation portion 24B and the fixing portion 23B corresponding to the holding portion 35 are provided, the removal of the substrate case 20 can be dealt with three times.

  As described above, the substrate case 20 and the substrate mounting apparatus according to the present embodiment leave a clear mark on the substrate case 20 and / or the case holder 30 when an illegal act is performed. The opening of the substrate case 20 due to the deformation of the lock pin cannot occur. On the other hand, the intentional removal of the substrate case 20 from the case holder 30 is very easy. In addition, the substrate case 20 can be easily reattached to the case holder 30.
