Description

  The present invention relates to an operation unit used in a spinning-type game machine called a pachislot machine, and more particularly to an integrated operation unit with a high degree of security that can effectively prevent an illegal act on an operation unit.

  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. Therefore, unauthorized actions such as remodeling of the main board for control (replacement of ROM, etc.) continue to occur, and in order to cope with this, the mounting apparatus for the main board for control is designed to prevent unauthorized modification. Various ideas have been taken (Patent Document 1).

JP 2001-170255 A

  However, fraudulent acts on gaming machines are becoming more sophisticated and complicated year by year, and the acts are not limited to the main board for control, but also extend to operation units such as stop switches. Specifically, a technique of interposing an illegal part in the wiring connector of the operation switch board is typical.

  Main operation switches in the gaming machine include a bed switch for inserting medals, a start switch, and a plurality of stop switches corresponding to the number of rotating drums. In a conventional gaming machine, these operation switches are arranged in the middle part of the front of the gaming machine with good operability, but each is independent in terms of mechanism, and against illegal acts such as remodeling. Does not have such measures.

  For example, a bed switch and a start switch are provided together with a medal slot or the like on the upper surface of a shelf-like operation unit formed in the middle stage. The plurality of stop switches are often unitized, and the unit is provided on the front surface or the upper surface of the shelf-like operation unit. Each of these operation switches has a dedicated board, and is connected to the control main board via a dedicated connector and wiring.

  The security level of the main board for control has been increasing year by year, and unauthorized modification to this has become difficult. On the other hand, the security level of the operation unit is low. Specifically, the wiring and connectors are exposed on the back side of the operation switch, and it is not so difficult to interpose an illegal part, and the number of wiring groups and connectors is large. For this reason, fraudulent acts on the operation unit are rapidly increasing.

  An object of the present invention is to provide an integrated operation unit for a gaming machine with a high degree of security that cannot substantially perform an illegal act. Another object of the present invention is to provide an integrated operation unit that is relatively easy to replace an internal substrate in spite of high security.

  In order to achieve the above object, the integrated operation unit of the present invention has a case in an airtight case in which operation switches such as a start switch and a stop switch in a rotary game machine are left with a trace when opened together with the board. The sealed case is sealed so that the switch can be operated from the outside, and the sealed case employs a configuration including a case body and a cover that is attached to the opening of the case body so as not to be detached by uneven fitting at a plurality of locations.

  Until now, the operation switches are distributed in a distributed manner for each type, and the back side wiring, board, etc. are rounded out, and no effective countermeasures are taken. On the other hand, in the integrated operation unit of the present invention, all the operation switches are provided together with the substrate in one sealed case. For this reason, fraudulent acts on the back side of the switch, wiring, and the board are virtually impossible. In addition, by centralizing the operation switches in the sealed case, only one connector with the main board for control is required, and by taking effective countermeasures against this, the countermeasures become more thorough and the cost of countermeasures is reduced. Is suppressed at low cost. It is impossible to open the connection between the case main body and the cover in the sealed case by the concave-convex fitting without leaving a trace. Therefore, in the unlikely event that the sealed case is destroyed, the trace remains clearly, so even if there is an illegal act, it can be detected immediately.

  In the integrated operation unit of the present invention, the display means for displaying the number of credits, the number of payouts, etc. is preferably provided in the sealed case together with the operation switch so as to be visible from outside the case, and is mounted on the substrate in the case. Is more preferable. By providing the display means in the sealed case together with the operation switch, the countermeasure against fraud becomes more complete, the configuration is simplified, and the economy is improved. When the display means is mounted on the substrate, the configuration is simpler and the economy is further improved.

  As a configuration of the sealed case, at least one of the case main body and the cover is integrally formed with partition ribs along the entire inner surface of the outer wall of the sealed case, and the portion corresponding to the front surface or the back surface of the at least one case. Preferably, a plurality of through holes are provided between the outer wall portion and the rib so as to surround the entire circumference. By providing a plurality of through holes so as to surround the entire circumference in a portion corresponding to the front or back surface of the sealed case, the front or back surface of the sealed case can be cut relatively easily with a tool such as a nipper. Since the partition ribs are provided inside the plurality of through holes and the substrate and the like are disposed and protected inside the ribs, there is no fear of improper acts on the substrate or the like from the plurality of through holes. That is, a plurality of through holes for incision do not cause fraud.

  As a connector with an external circuit such as a main board for control, a plug mounted on the surface of the board in the sealed case and a tip of the harness are connected and inserted into the plug to be in the inserted state. A detachable jack that can be locked and unlocked, a fixing base that is attached to the plug without the jack being inserted, and is fixed to the attached state by the jack inserted into the plug, and is inserted into the plug It is preferable to use a sealed connector that covers the jack and is detachably coupled to a fixing base attached to the plug, and has a protective lid that can be broken and is separated from the fixing base only by the breaking.

  In this sealed connector, when a fixing base is attached to the plug mounted on the surface of the substrate in the sealing case, and the jack is inserted and fixed in this state, the fixing base is fixed to the plug by the jack fixed to the plug. Is done. If a protective cover is attached to the fixed base, the plug and jack are covered and protected by the fixed base and the protective cover. The protective lid cannot be removed from the fixed base unless it is destroyed, and if it is destroyed, its trace remains clearly. For this reason, the illegal act to the connector main body which consists of a plug and a jack is prevented.

  When it is necessary for the gaming machine manufacturer or the hall side to open the sealed connector and replace the connector body, such as replacing the board in the sealed case, the protective lid is destroyed. Thereby, the protective lid is separated from the fixed base. When the protective cover is removed, the connector body is exposed and the jack can be removed. When the jack is released, the fixed base is released from the restraint by the jack and is released from the plug. Although the protective lid or the protective lid and the fixing base are destroyed and cannot be reused, the connector main body is not damaged and can be used as it is in the next connection. In the next connection, a new fixing base and a protective cover are required. However, compared with the case where the plug and jack are replaced, the labor and cost required for the replacement are significantly reduced.

  Here, a commercially available product can be used as the connector body, that is, the plug jack. One of the major features of this sealed connector is that it can be used repeatedly and its security level can be drastically improved by combining a fixed base and a protective lid with a commercially available connector.

  In order to confirm the state of the internal connector body, the protective lid is preferably made of a translucent resin that allows the inside to be seen through. For the same reason, the fixing base is also made of a translucent resin. preferable.

  When the connector body is removed, the protective lid is destroyed. In order to facilitate this destruction, the protective lid preferably has a linear bulging portion that can be easily cut and separated by a nipper or the like as the planned destruction portion. Needless to say, even in this configuration, traces of destruction remain clearly on the protective lid. Rather, by intentionally forming the part to be destroyed, it is easy to determine whether or not there is destruction.

  It is preferable that the linear bulging portion, which is a planned destruction portion, be provided at the central portion that bisects the protective lid on both sides. Thereby, a protective cover can be easily divided into both sides for 2 minutes, and the removal from a fixed stand becomes easy.

  The fixed base is locked at a fixed position by a jack inserted and fixed in the plug, but a harness connected to the jack can also be used as a locking portion for fixing the fixed base in the mounted state. By using the harness, it is possible to securely fix the fixing base to the jack with a simple configuration.

  The protective lid preferably has a stopper that holds the fixing claw provided in the jack in a locked state. According to this configuration, even if an outsider tries to operate the fixing claw of the jack to the released state by making a hole in the protective cover, the operation to the released state is prevented. Further, when an external force in the detaching direction is applied to the fixed base, an external force in the releasing direction may be applied to the fixing claw of the jack, but the operation of the fixing claw in the releasing direction is blocked. As a result, the security level of the connector body can be effectively increased.

  The fixing base and the protective cover can be used upside down according to the direction of the plug and jack.

  The integrated operation unit of the present invention is provided with operation switches such as a start switch and a stop switch in a rotary game machine so that they can be operated from the front in a sealed case where a trace remains when opened. Since the switch board is enclosed and sealed in the sealed case, illegal acts on the back side, wiring, and board of the operation switch can be made virtually impossible. Moreover, even if an illegal act is performed, the trace remains in the case, so that it can be detected immediately. By these, the security degree of an operation part can be raised significantly.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a use state of an integrated operation unit according to the first embodiment of the present invention, FIG. 2 is a perspective view showing the use state, FIG. 3 is a perspective view of the operation unit, and FIG. FIG. 5 is a partially broken perspective view of the unit, FIG. 5 is a sectional view taken along line AA in FIG. 3, and FIG. 6 is a rear view of the operation unit.

  The integrated operation unit according to the first embodiment is used as an operation unit of a rotary game machine called a throttle machine. More specifically, as shown in FIGS. 1 and 2, the middle stage in the front of the game machine 10 is used. It is attached to the part from the upper part to the lower part, and more specifically, the upper surface recess 12 of the shelf-like protruding part 11 formed as the operation part in the part from the middle part to the lower part of the front of the gaming machine 10 Used by fitting from above.

  As shown in FIGS. 3 to 6, the operation unit 20 includes a horizontally long sealed case 30 made of resin, an operation switch group 40 attached to the sealed case 30 so as to be operated from the upper side of the case, and a sealed case. 10 and a substrate 50 provided along the inner bottom surface thereof. The operation switch group 40 is mounted on the substrate 50 in addition to various electronic components related to the operation.

  The hermetic case 30 is a horizontally long rectangular parallelepiped with rounded corners on both sides of the front side, and includes a container-like case body 31 that forms a bottom portion thereof, and an inverted container-like cover 32 that is attached thereto. The case body 31 includes a bottom plate and a peripheral wall extending upward from the outer edge portion thereof. The upper end portion of the peripheral wall is thinner than other portions for fitting with the cover 32, and more specifically, the outer portion is thinner. In this thin fitting portion, a plurality of coupling and fixing fitting claws 33 are provided over the entire circumference at predetermined intervals. Each fitting claw 33 is formed between a pair of slits provided with a predetermined width in the thin fitting portion in order to impart deformability in the thickness direction, and has a protruding portion 34 protruding outward. ing.

  The cover 32 includes a top plate that is parallel to the bottom plate of the case body 31 and a peripheral wall that extends downward from the outer edge portion thereof. The top plate is provided with a plurality of openings corresponding to the operation switch group 40 so that the operation part of the operation switch group 40 protrudes upward. A large number of through holes 35 are provided on the outer edge of the top plate over the entire circumference at predetermined intervals. Each through hole 35 is a long hole extending along the outer edge of the top plate, and is designed to have a length and a width that allow the tip of the nipper to enter.

  The outer edge of the top plate is also provided with partition-like ribs 36 extending downward from the back surface of the top plate. The ribs 36 are located inside the numerous through holes 35 described above, and are formed in a circumferential direction along the inner surface of the peripheral wall so as to surround the inner side. The height of the rib 36 is substantially the same as the height in the sealed case 30, and the bottom plate is in contact with the bottom plate of the case main body 31 or with a slight gap in the state where the cover 32 is attached to the case main body 31. It is set to oppose. A substrate 50 is attached to a portion surrounded by the ribs 36 on the bottom plate.

  The lower end portion of the peripheral wall of the cover 32 is a thin fitting portion corresponding to the thin fitting portion formed at the lower end portion of the peripheral wall of the case body 31, and is thin due to the lack of the inner portion. And the recessed part 37 corresponding to the convex part 34 of the fitting nail | claw 33 mentioned above is provided in the inner surface of this thin fitting part at predetermined intervals in the circumferential direction. When the cover 32 is attached to the case body 31, the plurality of fitting claws 33 are elastically deformed inward, and the respective convex portions 34 are fitted into the corresponding concave portions 37. The convex portion 34 and the concave portion 37 are designed to have a shape that will not be detached without breaking the sealed case 10 once fitted.

  The operation switch group 40 is a push-down switch, and the upper surface operation part protrudes above the cover 32, and is provided with a 3-bet switch 41, a start switch 42, stop switches 43 to 45, and a determination key at the center in order from the left. A four-way switch 46. These switches are directly mounted on the substrate 50 in the sealed case 10.

  In addition to those shown, various switches are provided so as to protrude above the cover 32, and various display means are provided so that they can be seen through the top plate of the cover 32. These are also directly mounted on the substrate 50 in the sealed case 10 as with the operation switch group 40.

  The sealed case 10 is also equipped with a sealed connector 100 on the back for electrical connection between the board 50 in the case 10 and the main board for control provided in the gaming machine 10. The sealed connector 100 is connected to the control main board via the harness 60.

  Hereinafter, the structure of the sealed connector 100 will be described in detail with reference to FIGS. 5 and 7 to 13. 7 to 13 are perspective views showing the detailed structure of the sealed connector 100 from the back side of the operation unit.

  The sealed connector 100 uses a connector main body 120 made of a commercially available product (KEL8825 series). The connector main body 120 includes a plug 121 mounted on the surface of the substrate 50 in the sealed case 20 via a lead 70 and a jack 122 inserted therein. The plug 21 is a horizontally long rectangular resin block, and protrudes toward the back side of the case body 31 from a horizontally long opening 38 provided on the back side of the case body 31 of the sealed case 30 in order to receive the jack 22. .

  A jack 122 called a “resector pull” is a horizontally long rectangular resin block corresponding to the plug 121, and is connected to the tip of the belt-shaped harness 60, and is inserted into the plug 121 to be electrically connected to the plug 121. Is done. In order to prevent inadvertent detachment of the jack 122, the jack 122 is equipped with rotating fixed claws 123, 123 on both sides. The fixing claws 123, 123 on both sides have claw portions 124, 124 on the front end side of the vertical rotation fulcrum, and operation portions 125, 125 on the near side, respectively, and the operation portion 125 with the jack 122 not inserted. 125 are pushed inward, and the claw portions 124 are opened outward. When the jack 122 is pushed into the plug 121 from this state, the claw portions 124, 124 on the front end side are closed inward, and the operation portions 125, 125 on the front side are opened outward. When the claw portions 124 and 124 on the front end side are closed inward, the jack 122 is fixed to the plug 121 so as not to be detached. In this state, when the operation parts 125 and 125 on the front side are pushed inward, the claw parts 124 and 124 on the front end side are opened to the outside and detached from the plug 121, and the jack 22 can be detached from the plug 121.

  Such a connector main body 120 is combined with a fixing base 150 fixed to the connector main body 120 and a protective lid 160 attached to the fixing base 150 in order to prevent fraud. The fixing base 150 and the protective lid 160 are made of a transparent resin so that the state of the internal connector main body 120 can be visually recognized from the outside.

  The fixed base 150 is a rectangular frame that surrounds the plug 121. The fixing base 150 has a rectangular main body 151 fitted to the plug 121 and a square frame-shaped protection portion 152 integrally provided outside the main body 151 so as to surround the rear portion of the main body 151. Protrusions 153 for locking the protective lid 160 are provided on the rear outer surface of the main body 151, particularly on both sides of the upper surface and both sides of the lower surface. The protection part 152 surrounds the rear part of the main body part 151 leaving the lower center part, and is integrated with the main body part 151 at the rear end part. The reason why the lower central portion is an open portion is to form an opening for pulling out the harness 60 to the outside.

  The fixing base 150 is externally fitted to the plug 121 of the connector main body 120, and in this state, the jack 122 is attached to the plug 121 so that the fixing base 150 is fixed to the connector 120. Specifically, it is mainly prevented from coming off by the jack 122 inserted into the plug 121, particularly the harness 60 connected to the jack 122. More specifically, the end portion of the harness 60 is bent in an inverted U shape and fixed to the jack 122, the tip end portion protrudes below the jack 122, and the bent top portion 131 protrudes above the jack 122. . The fixing base 150 externally fitted to the plug 121 is mainly prevented from coming off by a jack 122 attached to the plug 121, particularly a bent top portion 61 of the harness 60 protruding upward from the jack 122, and is fixed to the connector main body 120. The Further, the operation portions 125 and 125 opened to the outside of the fixing claws 123 and 123 on both sides and the tip portion of the harness 60 protruding downward from the jack 212 also contribute to preventing the fixing base 150 from coming off.

  The protective cover 160 is a long rectangular cap-shaped resin body that is connected and fixed to the rectangular fixing base 150 and covers the connector main body 120. A plurality of openings 161 into which the protrusions 153 of the fixing base 150 are fitted are provided on the outer surface of the rear portion of the protective lid 160, particularly on both sides of the upper surface and both sides of the lower surface. At the rear part of the lower surface side of the protective lid 160, a notch part 162 that is long horizontally is provided, leaving both side parts. The notch 162 forms an opening for drawing the harness 60 to the outside in cooperation with the opening of the fixing base 150.

  A linear bulge 163 is received at the center of the protective lid 160. The linear bulging portion 163 is a semicircular curved portion having a convex outer cross section, and is provided on the upper surface portion, the front surface portion, and the lower surface portion of the protective cover 160 so as to divide the protective cover 150 into left and right parts. It has been. The bulging portion 163 can be easily excised with a nipper or the like. By this excision, the protective lid 160 is divided into left and right parts. A pair of stoppers 164 and 164 on both sides are provided on the front portion of the protective lid 160. The stoppers 164 and 164 are rods that protrude from the back surface to the back surface of the front portion, and the operation portions that are opened to the outside of the fixing claws 123 and 123 on both sides of the jack 122 in a state where the protective lid 160 is attached to the fixing base 150. It is located inside 125, 125 and prevents the operation units 125, 125 from moving inward. As a result, the jack 122 remains fixed to the plug 121.

  Next, the function of the integrated operation unit of the first embodiment will be described.

  As described above, the integrated operation unit 20 of the present embodiment is fitted into the upper surface recess 12 of the shelf-like protrusion 11 formed as an operation part in the part from the middle to the lower part of the front of the rotary game machine 10. Combined. The operation unit 20 fitted in the upper surface recess 12 of the shelf-like protruding portion 11 is fixed from within the gaming machine 10. The harness 60 drawn from the control main board in the gaming machine 10 is drawn into the upper surface recess 12 from the opening 13 provided on the rear surface of the upper surface recess 12, and the board in the operation unit 20 is sealed by the sealed connector 100. 50.

  The operation in the operation unit 20 during the game is not different from the operation unit so far.

  In this operation unit 20, all the operation switch groups 40 are gathered together with the display means and enclosed in the sealed case 30 together with the substrate 50, so that the back side of the switch and both surfaces of the substrate 50 are in the sealed case 30. Sealed and protected. When the cover 32 is attached to the case main body 31, the sealed case 30 cannot be detached due to the concave and convex fitting, and cannot be opened unless it is destroyed. In the case of destruction, since the trace remains clearly, it is very difficult to do fraudulent acts on the operation unit, which is virtually impossible, and the security level is dramatically improved. That is, the number of places where an illegal act can be performed on the operation unit is reduced and the difficulty level is increased.

  If the operation switch 40 in the sealed case 30 breaks down or the substrate 50 breaks down, these are investigated and replaced if necessary. In this case, the sealed case 30 must be opened. Since the case main body 31 and the cover 32 are firmly coupled, it is difficult to break for opening. However, in this sealed case 30, a large number of through holes 35 are provided on the outer edge of the top plate of the cover 32 over the entire circumference at predetermined intervals. First, the tip of the nipper is inserted into the specific through hole 35, and thereafter, the places where the through holes 35 are arranged are sequentially cut. By doing so, the top plate of the cover 32 can be cut easily. At this time, if the operation unit 20 is removed from the shelf-like protruding portion 11 of the rotary gaming machine 10, the operation is easy. It goes without saying that if a third party makes this incision, a large trace remains.

  Connection work and separation work in the sealed connector 100 are performed as follows. At this time, the operation unit 20 is removed from the shelf-like projecting portion 11 of the rotary gaming machine 10.

  When the connector main body 120 is connected in the sealed connector 100, the connector main body 120 mounted on the surface of the substrate 50 in the sealed case 30 and exposed to the back side of the sealed case 30 as shown in FIGS. 7 and 8. A square frame-shaped fixing base 150 is externally attached to the plug 121. Next, the jack 122 connected to the tip of the harness 60 is inserted into the plug 121. The inserted jack 122 is fixed to the plug 121 so as not to be detached by the fixing claws 123 on both sides. Specifically, the fixing claws 123 and 123 on both sides are rotated from the pre-expanded released state to the tapered locking state, and the claw portions 124 and 124 on the distal end side engage with the plug 121. Along with this, the operation units 125 and 125 on the front side spread outward. The fixing base 150 is prevented from being detached from the plug main body 120 and fixed by the protruding portion of the harness 60 of the jack 122 fixed to the plug 121 and the operation portions 125 and 125 on both sides.

  When the insertion of the jack 122 into the plug 121 and the fixing base 150 are fixed, as shown in FIGS. 9 and 10, a square cap-shaped protective lid 160 is pushed into the fixing base 150 and fixed. The rear part of the protective cover 160 is inserted between the main body 151 and the protective part 152 of the fixed base 150, and the four protrusions 153 of the fixed base 150 are fitted into the four openings 161 of the protective cover 160, thereby protecting the protective cover 160. The lid 160 is fixed to the fixed base 150 so as not to be detached. Since the stoppers 164 and 164 exist inside the operation portions 125 and 125 of the fixing claws 123 and 123 of the jack 120, there is no danger that the fixing claws 123 and 123 operate in the releasing direction. In particular, the fixing claw 123 does not rotate even if an illegal act such as making a hole in the side surface of the protective cover 160 and removing the jack 122 (pressing the operation portion 125 of the fixing claw 123 inward) is attempted. Can prevent illegal acts.

  The harness 60 is pulled out from the plug 122 through the space between the fixing base 150 and the protective cover 160.

  The protective lid 160 fixed to the fixed base 150 is not detached from the fixed base 150 unless it is destroyed. If the protective cover 160 is destroyed and an illegal act is performed on the internal connector 120, even if the protective cover 160 is remounted, a trace of destruction remains clearly on the protective cover 160. I understand. Since both the fixing base 150 and the protective lid 160 are made of transparent resin and the inside can be visually confirmed, the state of the internal connector body 120 can be monitored from the outside. As described above, the fixed base 150 and the protective lid 160 can be used upside down.

  When the substrate 50 in the sealed case 20 is defective or fails, the substrate 50 must be replaced. At that time, it is necessary to intentionally pull out the jack 122 from the plug 121 of the connector main body 120. In this case, as shown in FIG. 11, the linear bulging portion 163 provided in the central portion (upper surface, front surface, lower surface) of the protective lid 160 is cut out with a tool such as a nipper. As a result, the protective lid 160 is divided into left and right parts. If divided into left and right parts, as shown in FIGS. 12 and 13, a tool such as a screwdriver is inserted into the divided part, and the protective lid 160 is half-opened and separated from the fixed base 150. In this way, the protective lid 160 is relatively easily broken by the excision of the bulging portion 163 and can be removed from the fixed base 150.

  When the protective lid 160 is removed, the jack 122 of the connector main body 120 is pulled out from the plug 121 by a normal operation. That is, the fixing claws 123 and 123 on both sides are operated from the locked state to the released state, and the jack 122 is pulled out to the front. If the protective lid 160 is removed, there is no blocking by the stoppers 164 and 164, so that the fixing claws 123 and 123 are operated smoothly. Thereby, it can isolate | separate, without damaging the connector main body 120 which is a commercial item. When the replacement of the board 50 is completed, the jack 122 is inserted into the plug 121 again.

  14 is a perspective view showing a use state of an integrated operation unit according to the second embodiment of the present invention, FIG. 15 is a perspective view showing the use state, FIG. 15 is a perspective view of the operation unit, and FIG. FIG. 18 is a partially broken perspective view of the unit, and FIG. 18 is a sectional view taken along line B-B in FIG.

  The functions of the integrated operation unit of the second embodiment are as follows.

  As with the integrated operation unit 20 of the first embodiment, the integrated operation unit 20 of the second embodiment is a shelf that is formed as an operation unit in a portion from the middle to the lower part of the front of the rotary gaming machine 10. It fits into the upper surface recess 12 of the protrusion 11. The operation unit 20 fitted in the upper surface recess 12 of the shelf-like protruding portion 11 is fixed from within the gaming machine 10. The harness 60 drawn from the control main board in the gaming machine 10 is drawn into the upper surface recess 12 from the opening 13 provided on the rear surface of the upper surface recess 12, and the board in the operation unit 20 is sealed by the sealed connector 100. 50.

  The operation in the operation unit 20 during the game is not different from the operation unit so far.

  In this operation unit 20, all the operation switch groups 40 are grouped together with the display means and enclosed in the sealed case 30 together with the substrate 50, whereby the back side of the switch and both surfaces of the substrate 50 are sealed in the sealed case 30. Enclosed and protected. When the cover 32 is attached to the case main body 31, the sealed case 30 cannot be detached due to the concave and convex fitting, and cannot be opened unless it is destroyed. In the case of destruction, since the trace remains clearly, it is very difficult to do fraudulent acts on the operation unit, which is virtually impossible, and the security level is dramatically improved. That is, the number of places where an illegal act can be performed on the operation unit is reduced and the difficulty level is increased.

  If the operation switch 40 in the sealed case 30 breaks down or the substrate 50 breaks down, these are investigated and replaced if necessary. In this case, first, the operation unit 20 is removed from the shelf-like projecting portion 11 of the rotary gaming machine 10, the bottom surface of the sealed case 30 is exposed, and then the sealed case 30 is opened. Since the case main body 31 and the cover 32 are firmly coupled, it is difficult to break for opening.
