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. The present invention also relates to a gaming machine itself that includes the board case and the board mounting device.

  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. Further, Patent Documents 2 to 4 have been published as other illegal modification techniques.

  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.

 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. When the caulking seal part is broken with a tool such as a nipper, the trace remains clearly, and the trace can be found immediately when the front door of the gaming 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. When the case is illegally opened in this way, there is a problem that almost no trace of unauthorized opening remains in the case, 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. It is another object of the present invention to provide a gaming machine in which security is remarkably improved by incorporating a substrate case and a substrate attachment device.

In order to achieve the above object, the circuit board case of the present invention according to claim 1 encloses a circuit board for a gaming machine in a box-shaped internal space formed by fitting the case main body and the cover. a board case that, with the both sides of the upper surface of the vertical and horizontal upper sidewall of the case body and the cover to be box-shape by the side walls of the surrounding back plate, and each protrusion is formed in a corresponding position, the One of the protrusions is provided with a holding part that holds the lock pin unit in two directions, inward and outward, and the other of the protrusions is a fitting hole into which the lock pin of the lock pin unit is fitted. And a first pin operation part comprising a pair of claw parts sandwiching the holding part from both sides is provided, and with the closing operation of the case main body and the cover whose lower edge part is rotatably engaged, Lock pin of the lock pin unit held by the protrusion However, the case main body and the cover are fixed so that they cannot be opened by entering the fitting hole of the first pin operation portion provided in the other protrusion, and the case main body notch portion is provided between the case main body protrusion. A fixing portion for fixing the substrate case to the case holder is provided between the protruding portions of the cover, and the fixing portion fixes the substrate case to the case holder through the notch portion of the case body. It is characterized by that.
A substrate case according to a second aspect of the present invention is the substrate case according to the first aspect, wherein the fixing portion is a lock pin unit held by one of the fixing portions in accordance with the closing operation of the substrate case and the case holder. The lock pin enters the fitting hole of the second pin operation portion provided in the other fixing portion, and the substrate case and the case holder are fixed so as not to be opened.
The gaming machine of the present invention according to claim 3 is a gaming machine in which the board case is held in a case holder fixed in the machine, and the board case is formed by a box body formed by fitting the case main body and the cover. A circuit board for gaming machines is enclosed in the internal space, and a box-like case body is formed by the back plate and the surrounding upper, lower, left and right side walls, and both sides of the upper surface of the upper side wall of the cover protrude at corresponding positions. And a holding portion that holds the lock pin unit in two directions, inward and outward, is provided on one of the protrusions, and the lock of the lock pin unit is provided on the other of the protrusions. A first pin operating portion having a fitting hole for fitting a pin and having a pair of claws sandwiching the holding portion from both sides is provided, and the lower body is rotatably engaged with the case body and the cover. Along with the closing operation, one protrusion The lock pin of the held lock pin unit enters the fitting hole of the first pin operation part provided in the other protrusion, and the case body and the cover are fixed so as not to be opened, and the protrusion of the case body A notch is formed in the case body, and a fixing part for fixing the substrate case to the case holder is provided between the protruding parts of the cover. The fixing part passes through the notch part of the case body. The substrate case is fixed to the case holder.

  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.

  Further, the board mounting device of the present invention includes a rectangular transparent board case enclosing a control board for a gaming machine, and a gaming machine with the board case fitted to fix the board case in the gaming machine. A board mounting device composed of a combination with a square case holder fixed to the inner surface, and after the board case is fitted in the case holder, it is configured to be slidable in the direction along the case surface in the case. It is configured so that it cannot be separated from the case holder in a slid state, and a lock pin is housed in either one of the opposing surfaces of the substrate case and the case holder so that the lock pin can be moved forward and backward, and locked in the advance direction from the pin holder. There is provided a pin unit holding portion for holding the lock pin unit with the pin biased toward the other facing surface, and the other facing surface is provided. The second pin operation unit for pushing the lock pin into the pin holder with the board case fitted in the case holder, and protruding the lock pin while sliding from the fitted state to fix the board case in the sliding position. It is the board | substrate attachment apparatus provided.

  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.

  In the board mounting apparatus of the present invention (Claim 1), a board case for enclosing a control board for a gaming machine inside, and an inner surface of the gaming machine are fixed to the board case for fitting and fixing in the gaming machine. A substrate mounting apparatus comprising a combination with a case holder, wherein the substrate case is configured to be slidable in a direction along the surface of the case in the case after being fitted in the case holder, and the case holder in a slid state. The lock pin is housed in either one of the opposing surfaces of the substrate case and the case holder so that the lock pin can be advanced and retracted, and the lock pin is urged from the pin holder in the advancing direction. A pin unit holding portion is provided to hold the lock pin unit toward the other facing surface, and a board case is attached to the other facing surface. A lock pin is pushed into the pin holder in a state of being fitted in the holder, and a second pin operation portion is provided for fixing the board case in the slide position by projecting the lock pin in a state of sliding from the fitted state. .

  In the substrate mounting apparatus of the present invention, in the substrate mounting apparatus according to claim 1, the substrate case includes a case body whose front surface is open and a front opening portion of the case body which is sealed, and the control substrate is enclosed in the case. The cover is engaged with a specific edge of the case main body so as to be tiltable with the edge as a rotation fulcrum, and is provided on the edge on the open side opposite to the fulcrum side. The lock mechanism is fixed to the case main body so as not to be opened, and the lock mechanism is built-in and held in a direction intersecting the opening / closing direction of the cover at the opening side edge of either the case main body or the cover, The lock pin is accommodated in the holder so that the lock pin can be moved forward and backward, and the lock pin unit is urged in the advancing direction from the pin holder, and the taper provided on the open side edge of the other member As a result of the closing operation of the cover, the lock pin is pushed into the pin holder, and the lock pin protrudes and fits into the fitting portion provided on the back side of the tapered portion, so that the edge on the open side of the cover is It has the 1st pin operation part fixed to a closed state, It is characterized by the above-mentioned.

  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 an illegal act against the control substrate from the back surface of the substrate case.

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, in the upper edge portion, as shown in FIGS. 8A to 8C, in the lock pin units 40 and 40 held by the case main body 20A, the first pin operation portion 22B of the cover 20B, particularly the claw portion. The lock pin 41 is pushed into the pin holder 42 by the tapered portion 28B of 26B, 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, the substrate 10 in the case body 20A is not shown in FIG.

  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.

Second embodiment:
Another embodiment (improvement of the first example) of the present invention will be described in detail with reference to FIGS. 12 to 22 and additional drawings corresponding to FIGS. 1 to 11 used in the first example. In addition, about the same or similar structure already demonstrated in the 1st Example, the overlapping part may be abbreviate | omitted. For convenience of explanation, the directions of up and down, left and right, and front and back sides shown in the drawings are defined. In the other drawings, description will be made using basically the same direction.

  As shown in FIGS. 12 to 14, the board mounting apparatus according to the present embodiment is provided with a board 10 that is susceptible to fraud such as a main board for control or a sub board of a gaming machine (such as a pachinko machine or a pachislot machine). Used to attach to a vertical inner surface (eg, back or side).

  This substrate mounting apparatus is used for a case holder 30 that is directly mounted on the inner surface of a gaming machine, a substrate case 20 that encloses a substrate 10, a plurality of substrates used for sealing the substrate case 20 and connecting and fixing the substrate case 20 and the case holder 30. The lock pin unit 40 is provided. The lock pin unit 40 is the same and has a structure that can be shared for sealing and connecting and fixing.

  The substrate case 20 of this embodiment is a thin resin case having a horizontally long rectangle corresponding to the shape of the substrate 10 enclosed in the inside (in this case, a rectangle), and is formed of a transparent resin so that the state of the substrate 10 can be clearly understood. Has been. The substrate case 20 includes a case main body 20A whose front side is open (front opening) and a cover 20B that covers the entire front opening and closes (or covers) (particularly, see FIG. 14).

  The outer shape of the case main body 20A is a substantially concave-shaped back plate with an outer frame surrounding its periphery, resulting in a concave basin shape with an open front. In other words, the case main body 20A is formed of a rectangular back plate and a rectangular frame-shaped side wall that surrounds the rectangular back plate. Projecting portions 23A, 23A projecting in a convex shape on both the left and right sides.

  Each of the two protruding portions 23A also has a back plate and a square frame-like side wall, and has a rectangular tray shape like the substrate housing portion 21A. That is, the case main body 20A has a rectangular tray-shaped substrate housing portion 21A and two rectangular tray-shaped protrusions 23A that are integrally provided on the left and right ends of the upper side wall of the case body. Is a concave tray.

  A cylindrical unit holding portion 24A for holding the lock pin unit 40 is integrally provided on each front side of the protruding portions 23A and 23A on both sides. The holding portions 24A, 24A on both sides hold the lock pin units 40, 40 along the upper edge of the case in a posture facing the inside or the outside (in the figure, both the lock pin units 40, 40 face the inside). Further, a concave notch 25A (see particularly FIG. 16) is formed between the protruding portions 23A and 23A on both sides.

  The case body 20A is integrally provided with hook portions 22A, 22A extending downward from the lower surface of the lower side wall of the substrate housing portion 21A, and a lower edge portion of a cover 20B described later is rotatably engaged. For example, the hook portion 22A has a hook hole at the lower edge portion of the case body 20A and a hook claw at the lower edge portion of the cover 20B. The position configuration may be reversed (that is, the hook claw on the case body 20A and the hook hole on the cover 20B).

  As shown in FIG. 15, the lock pin unit 40 includes a bullet-shaped lock pin 41 whose tip is curved in a dome shape, a cylindrical pin holder 42 that slidably supports the lock pin 41 in the central axis direction, In order to urge the pin 41 toward the distal end side, the pin 41 includes a spring 43 made of a coil spring accommodated in a compressed state in the pin holder 42. The lock pin 41 is prevented from coming off to the tip end side, and almost half of the entire length is elastically protruded toward the tip end side of the pin holder 42 by the pressing force of the spring 43 when no external force is applied.

  The spring 43 is inserted in a compressed state between the stopper 45 at the rear end portion (bottom surface) of the pin holder 42 and the lock pin 41 in the pin holder 42, and elastically presses the lock pin 41 toward the front end side. In this state, when an external force is applied to the curved portion formed at the distal end portion of the lock pin 41 from a direction perpendicular to the central axis, the lock pin 41 enters the pin holder 42 against the urging force of the spring 43. Retreat. A locking flange portion 44 that is engaged with the end portion of the unit holding portion 24 </ b> A is provided at the end portion on the distal end side of the pin holder 42.

  As shown in FIGS. 12 to 14, the cover 20 </ b> B of the substrate case 20 is a rectangular box having a relatively thin thickness with the back surface opened (opened) so as to completely cover the concave tray-shaped case body 20 </ b> A. A front plate provided with a plurality of openings 25B for fitting a plurality of connectors 11 to be exposed to the front side is provided with a rectangular outer frame surrounding the periphery, and has a box lid shape with an open back surface. . In other words, the cover 20 </ b> B is long horizontally to enclose the substrate 10 by a rectangular front plate provided with a plurality of openings 25 </ b> B into which the connector 11 is fitted and a rectangular frame-like side wall surrounding the cover. A rectangular box lid-shaped substrate housing portion 20C (see FIG. 14) and a box lid-shaped mounting portion 21C (see FIG. 14) having the same lateral width and an open back surface are integrally provided on the upper surface of the upper side wall. Yes. The attaching portion 21C includes left and right protruding portions 21B, which will be described later, and fixing portions 23B and 23B therebetween. Note that the opening 25B can be freely provided as necessary.

  On the lower surface of the lower side wall of the cover 20B, a cover hook portion (not shown) that engages with the hook portions 22A and 22A described above is formed. For example, the cover hook portion is a hook claw formed on the lower edge portion of the cover 20B, and engages with the hook hole 22A on the lower edge portion of the case body 20A. By engaging the hook portions of the case main body 20A and the cover 20B, the two are hinge-coupled so as to be openable and closable with the lower edge portion as a rotation fulcrum (see FIG. 16).

  Four cylindrical bosses are erected in the vicinity of the inner side of the back surface of the front plate of the cover 20B in the back surface direction, and the substrate 10 positioned in the substrate housing portion 20C by the bosses is formed at the upper end of the boss. It is fixed with screws by screw holes. That is, since the board 10 and the cover 20B are positioned and fixed first, the connector 11 and the opening 25B can be fitted without a gap, and after that, the assembled cover 20B is simply rotated together with the case body 20A. Accurate positioning is unnecessary, and the assembly of the substrate case 20 itself becomes easy.

  When viewed partially, the both sides of the cover 20B protrude upward in a convex shape corresponding to the protrusions 23A and 23A of the case body 20A. In other words, in a state where the fixing portion 23B is removed from the mounting portion 21C, only the substrate housing portion 20C and the left and right protrusions 21B and 21B are provided, and the box has the same outer shape as the case main body 20A and the back surface is opened. It becomes a lid shape. However, since the cover 20B is integrally molded, the fixing portion 23B cannot be removed from the attachment portion 21C.

  On the back side of the protrusions 21B and 21B on both sides, a first pin for operating the lock pin units 40 and 40 held on the front side of the protrusions 23A and 23A (operating to move the lock pin 41 back and forth) Operation portions 22B and 22B (FIGS. 17 to 19) are formed. The detailed configuration of the first pin operation units 22B and 22B will be described later with reference to FIGS.

  A plurality of fixing portions 23B, 23B,... Formed integrally to fix the substrate case 20 to the case holder 30 are provided between the protruding portions 21B, 21B on both sides. A plurality (four in this case) of the plurality of fixing portions 23B, 23B,... Are arranged side by side between the protruding portions 21B, 21B. Each of the fixing portions 23B has a cylindrical shape protruding to the front side (see FIG. 17), and operates another lock pin 40 for fixing the substrate case 20 to the case holder 30 (an operation for retreating the lock pin 41). ) Is formed inside (see FIG. 22). The configuration of the second pin operation unit 24B will be described in detail in the description of the substrate mounting apparatus later. In addition, in these figures, although each fixing | fixed part 23B is made into the cylindrical shape which protrudes to the front side, it may be filled with resin and you may make it the same height as the front board of the cover 20B. Each fixing portion 23B is formed with a tool hole 23C (length 3 mm × width 10 mm × depth 10 mm, see FIG. 20B) for inserting a breaking tool. If it is plunged and bent so as to bend up and down with force, only one fixing part 23B is destroyed. As a result, since the fixing by the lock pin unit 40 is released, the substrate case 20 can be slid up and taken out from the case holder 30.

  Similarly, tool holes 26C (length 10 mm × width 3 mm × depth 10 mm, see FIGS. 19C and 20B) are also formed in the individual (four in the drawing) first pin operation portions 22B. If it is bent left and right, only one first pin operation part 22B can be destroyed. As a result, the fixing by the lock pin unit 40 is released, so that the substrate case 20 taken out from the case holder 30 can be opened and the control board 10 can be taken out again (see FIG. 16). The tool hole 23C and the tool hole 26C are representatively described in FIGS. 19C and 20B, and all have the same structure even if not shown in other drawings.

  As shown in FIGS. 17 and 18, the first pin operating portions 22B and 22B formed on the back side of the protruding portions 21B and 21B of the cover 20B are each holding portions 24A of the case main body 20A with the substrate case 20 closed. It consists of a pair of nail | claw part 26B, 26B which pinches | interposes from both sides. Each claw portion 26B protrudes from the front side to the back side of the cover 20B, and in a state where the substrate case 20 is closed, a circular penetration into which the lock pin 41 of the lock pin unit 40 held by the holding portion 24A is fitted. 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 in accordance with the closing operation of the substrate case 20, and guides it to the through hole 27B (see FIG. 19). Although only described in FIG. 19 (C), the tool holes 26C are formed in all the claw portions 26B, and the depth is up to the top of the through holes 27B. The pin 41 cannot be unlocked by operating from the outside. As a result, it is possible to prevent cheating, and when the claw portion 26B is destroyed, the trace remains so that it can be determined at a glance that there has been cheating.

  Further, in order to prevent unauthorized operation of the lock pin unit 40 with respect to the lock pin 41 in the state in which the substrate case 20 is closed, the first pin operation portion 22B is completely surrounded by the box-shaped protruding portion 21B. And 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. That is, even if an attempt is made to make a hole with a drill from the left side wall in FIG. 19C, the protective plate 29B obstructs and the trace remains when the hole is made.

  As shown in FIGS. 12 to 14, the case holder 30 that constitutes the substrate mounting apparatus together with the substrate case 20 is a thin outer box having a rectangular shape in which the substrate case 20 is fitted from the front side and the front surface being opened. The board case 20 fitted into the board 30 is configured to slide downward (see FIG. 20). Four screw holes 31 are provided in the central portion of the back plate 38 of the case holder 30 to fix the holder to the inner surface of the gaming machine. Further, on both sides of the lower end, overhang portions 36 and 36 with screw holes are provided for attaching protective members (not shown) that cover the plurality of connectors 11. Thereby, fraudulent acts can be prevented.

  Two types of hooks 32 and 33 are provided on the uppermost portion of the back plate 38 to lock the substrate case 20 as the substrate case 20 fitted in the holder 30 slides downward. In the state where the substrate case 20 is completely slid downward, the screw fixing the case holder 30 to the inner surface of the gaming machine is hidden, so that the case holder 30 cannot be removed.

  The two types of hooks 32 and 33 protrude from the back plate 38 of the case holder 30 to the front side, and the tip end portion is bent upward in a bowl shape (that is, an L-shaped hook). As shown in FIGS. 20 and 21A, 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. As shown in FIG. 21B, the second hook 33 has the same principle as that of the first hook 32. 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 sandwiches and fixes the lowermost part of the substrate case 20. That is, the substrate case 20 can be slid up and down by the first hook 32, the second hook 33, and the third hook 34, but the case holder 30 cannot be detached from the front side. As will be described later, the lock pin unit 40 held by the pin unit holding portion 35 prevents the substrate case 20 from sliding up and down.

  A plurality of pin unit holding portions 35, 35... Are provided on the uppermost portion of the back plate 38 of the case holder 30. The 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. Yes. Each pin unit holding part 35 is a cylindrical body protruding from the back plate 38 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 (that is, between the protrusions 23A and 23A), when the substrate case 20 is fitted to the case holder 30, The plurality of pin unit holding portions 35, 35... Do not interfere with the upper edge portion of the case main body 20A of the substrate case 20 (that is, the attachment portion 21C to the fixing portion 23B). Thereby, the lock pin unit 40 held by the holding portion 35 is operated by the second pin operation portion 24B formed on the back side of the fixing portion 23B of the cover 20B of the substrate case 20 in accordance with the slide from the top to the bottom. Is done.

  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. When the substrate case 20 is completely slid downward, the lock pin 41 is fitted into the cylindrical fixing portion 23B and fixed to the case holder 30. 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 positioned in the substrate housing portion 20C by the cylindrical boss of the cover 20B constituting the substrate case 20, and the connector 11 and the opening 25B are fitted and fixed with screws. Further, the lock pin units 40, 40 are set outwardly in the holding portions 24A, 24A formed on the protruding portion 23A (both sides of the upper edge portion) of the case body 20A. This is for reliably sealing the left and right sides of the substrate case 20. In addition, as shown in FIG. 14, there is no problem even if the mounting direction of the lock pin units 40, 40 is inside.

  When the above preparation is completed, the cover 20B is attached to the case body 20A as shown in FIG. Specifically, the hook portions 22A, 22A formed on the lower edge portion of the case body 20A are engaged with the hook portions of the cover 20B corresponding to the hook portions 22A, 22A, and the two are hinged (for example, the lower edge of the case body 20A) The hook claw at the lower edge of the cover 20B is engaged with the hook hole formed in the portion). In this state, the cover 20B and the case body 20A are closed by applying an external force in the closing direction (clockwise in FIG. 16) to the upper edge on the open side of the cover 20B. Then, in this upper edge portion, as shown in FIGS. 19A to 19C, in the lock pin units 40 and 40 held by the case body 20A, the first pin operation portion 22B of the cover 20B, particularly the claw portion. The lock pin 41 is pushed into the pin holder 42 by the tapered portion 28B of 26B, 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. In FIG. 16, the substrate 10 is fixed in the cover 20B.

  Thus, when the substrate 10 is completely enclosed in the substrate case 20 (in the enclosed space formed by the case main body 20A and the cover 20B), the substrate case 20 is fixed to the vertical inner surface of the device with screws through the screw holes 31. The case holder 30 is attached. This is done in the following procedure.

  As shown in FIGS. 13 and 14, a lock pin unit 40 is inserted and set in one of a plurality of holding portions 35, 35... Aligned on the upper edge of the case holder 30 (particularly, FIG. 13 lock pin units 40). In this state, as shown in FIGS. 20A and 20B, the substrate case 20 is inserted into the case holder 30 (see FIG. 20A) and slid downward (see FIG. 20B). 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. 22A and 22B, 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 pin enters the cylindrical fixing portion 23B from the state in which it is pushed into the pin holder 42 (see FIG. 22A) (see FIG. 22B). . Thereby, the upward sliding movement of the substrate case 20 is prevented, 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 slide types that move back and forth 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 and the substrate case 20 is locked, the substrate case 20 is opened in the vicinity of the lock pin units 40 and 40 unless the substrate case 20 is largely destroyed. Is impossible. When the substrate case 20 is largely destroyed, the trace clearly remains in the substrate case 20 (that is, when the substrate case 20 is opened, a trace of the destruction of the entire first pin operation unit block always remains). . Further, since the front side of the lock pin unit 40 (outside the claw portion 26B) is reinforced by the protection plate 29B, it is more difficult to break the substrate case 20 for externally operating the lock pin 41.

  Similarly, since the same lock pin unit 40 enclosed in 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. Removal 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 (visually confirm) 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 (or only one fixing block including the fixing portion 23B is destroyed by the above-described destruction method using the tool hole 23C). Then, the lock pin 41 can be pushed in (or when the lock is released), 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.

  When the substrate case 20 is set again in the case holder 30 after the inspection, the lock pin unit 40 faces the other side of the plurality of holding portions 35, 35. Set 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.
