Depending on the mechanism that discharges the ball and the prize ball, the game balls collected by winning the various prize holes provided on the game board and the game balls collected from the outlet without winning any of the prize holes Game control device 7 that controls the progress of the game centrally by controlling the operation of various game devices provided on the game board, etc. Various devices such as a discharge / launch control device 8 that controls the firing of the hit ball and a power supply device 9 that supplies a predetermined power to each part are provided at appropriate positions.

  The various devices provided on the back side of the gaming machine 1 are indispensable for smooth control of the game, and the reliability of the gaming machine 1 is deteriorated if it is tampered or intentionally malfunctioned. In particular, the game control device 7 that performs overall control of game progress stores and holds a game control program and the like, and therefore, it is necessary to ensure its secrecy, so that opening is restricted. . Hereinafter, the detailed structure of the game control device 7 will be described.

  FIG. 3 is an external perspective view of the game control device 7. A game control board 20 having a substantially rectangular shape, on which various electronic / electrical parts and connectors for executing control related to the operation of the gaming machine 1 are mounted, is made of synthetic resin. The base member 30 is made of a base member 30 and a lid member 40, and a fastening portion 51 (see FIG. 4) provided on the base plate box 50 is covered with a cover member 60. The cover member 60 is not destroyed. It is fixed to the substrate box 50 by the fixing means 70 which is fixed so that it cannot be removed. In addition, each connector 21 ... of the game control board 20 is exposed outside via the connector insertion part of the cover member 40, in order to attach the cord side connector connected to the various wiring cords extended from an electrical component. .

  Further, in the board box 50, for example, engaging portions 52, each including an engaging receiving member provided on the base member 30 and an engaging convex piece provided on the lid member 40, are appropriately formed, and the base member 30 and the lid member are formed. If the base member 30 and the lid member 40 are slid in the engagement direction, the base member 30 and the lid member 40 are brought into an engaged state where the base member 30 and the lid member 40 are relatively slid in the counter-engagement direction. The lid member 40 returns to the disengaged state where it can be separated.

  If the board box 50 containing the game control board 20 is not easily opened by the detachable engaging part 52, the protruding plate part 32 provided on the side of the locking part forming wall 31 of the base member 30 will be described. With respect to the screw receiving hole 33, the screw 44, which is a fastening member screwed and held on the screw fastening portion 43 of the protruding plate portion 42 provided on the locking portion forming wall 41 of the lid member 40, can be screwed. (See FIG. 5 (a)).

  Then, in the board box 50 in which the base member 30 and the lid member 40 are engaged, when the screw 44 is screwed into the screw receiving hole 33, the base member 30 and the lid member 40 are slid so as to return to the non-engaged state. The board box 50 is closed. On the other hand, when the screw 44 is removed from the screw receiving hole 33, the base member 30 and the lid member 40 can be slid to return to the non-engaged state, and the substrate box 50 becomes openable.

  That is, in the gaming machine 1 shown in the present embodiment, the screw receiving hole 33 provided in the protruding plate portion 42 of the base member 30 and the screw fixing portion 43 provided in the protruding plate portion 42 of the lid member 40 cooperate with each other. Wearing portion 51 (a closed state in which the lid member 40 and the base member 30 are fastened by the fastening member, and an openable state in which the lid member 40 and the base member 30 can be opened by releasing the fastening by the fastening member) And a fastening part that can be converted into). The fastening portion 51 may be provided at one place, but in this configuration example, if seven places are provided side by side and the screws 44 are not attached to and detached from all the fastening portions 51. Cannot be converted into a closed state or an openable state.

  Further, a retaining protrusion 44 a is provided at an appropriate position on the outer periphery of the screw 44, and the retaining protrusion 44 a comes into contact with a barrier portion 43 a that narrows the inner space of the screw fixing portion 43, so that the screw 44 is screwed. It prevents from falling off from the portion 33. That is, in the present configuration example, the retaining protrusion 44a provided on the screw 44 and the barrier portion 43a provided on the screw fixing part 43 cooperate with each other. Even if it can be opened, it functions as a “screw removal prevention means for preventing the screw from being removed from the fastening portion”. Further, when the screw 44 is not screwed into the screw receiving hole 33, the head of the screw 44 protrudes from the top 43b of the screw fastening portion 43 (see FIG. 5A). When 44 is screwed into the screw receiving hole 33 to an appropriate length, the head of the screw 44 does not protrude beyond the top 43b of the screwing portion 43 (see FIG. 5B).

  The cover member 60 that covers the fastening parts 51 that are configured as described above is attached to the lid member 40 side so as to cover the top part 43b of the screwing part 43, for example, so that the screw 44 that is the fastening member cannot be operated. . Therefore, the cover member 60 includes a main cover wall 61 that covers the top portions 33b of the screw fastening portions 33 in a state in which one side edge is in contact with the wall surface of the locking portion forming wall 41 of the lid member 40. The overlapping portion forming wall 62 that is connected to the other side edge of the main cover wall 61 and is substantially parallel to the fixing portion forming wall 41 of the lid member 40, and the both side edges of the main cover wall 61 and the overlapping portion forming wall 62, respectively. A first side wall 63 and a second side wall 64 are provided.

  When the cover member 60 is properly attached to the substrate box 50, as shown in FIG. 5B, the edge of the fixing portion forming wall 41 of the cover member 60 comes into contact with the protruding plate portion 32 of the base member 30, and The first and second side walls 63 and 64 come into contact with the locking portion forming wall 41 and the protruding plate portion 42 of the lid member 40, respectively, and the main cover wall 61 covers the top portion 43b of the screwing portion 43. At this time, a plurality (for example, four) of cover side overlapping portions 65 formed on the overlapping portion forming wall 62 of the cover member 60 and a plurality (for example, four) formed on the protruding end of the protruding plate portion 32 of the base member 30. The box-side overlapping portions 34 overlap with each other to constitute the fixing means 70.

  The cover side overlapping portion 65 includes a cut portion 65a protruding from the overlap portion forming wall 62 and a fixing portion 65b provided on the extending end side of the cut portion 65a. Similarly, the box side overlapping portion 34 includes a cut portion 34a protruding from the protruding plate portion 32 of the base member 30, and a fixing portion 34b provided on the extending end side of the cut portion 34a. When the cover member 60 is properly attached to the substrate box 50, the fixing hole of the fixing portion 65b of the cover side overlapping portion 65 and the fixing hole of the fixing portion 34b of the box side overlapping portion 34 are in communication with each other. When the one-way screw 71 that cannot be loosened is tightened from the fixing portion 65b to the fixing portion 34b, the one-way screw 71 cannot be removed from the fixing portions 65b and 34b, so that the cover member 60 cannot be removed from the board box 50. Further, the cut portions 65a and 34a are portions that can be cut relatively easily with a cutting tool such as a nipper, and the cut portions 65a and 34a are cut while the cover side overlapping portion 65 and the box side overlapping portion 34 are overlapped. When the fixing means 70 is destroyed, the fixing portions 65b and 34b fixed by the one-way screw 71 are removed, and the cover member 60 can be removed from the substrate box 50.

  As described above, in the gaming machine 1 according to the present embodiment, the cover member 60 is fixed to the board box 50 by the fixing means 70 that cannot be removed unless the cover member 60 is broken. In order to open the substrate box 50, it remains as a history of removal, and the screws 44 of all the screwing portions 43 are converted so that the fastening portions 51, which appear when the cover member 60 is removed from the substrate box 50, can be opened. Must be removed. That is, in order to cheat on the game control board 20 of the game control device 7, it takes a long time to remove the screws 44 in all the fastening portions 51. It is difficult to prevent fraud.

  In addition, the game control board 20 has various electronic / electrical parts mounting surfaces facing the inner space of the lid member 40, and the electronic / electrical parts non-mounted surface faces the opening side of the lid member 40. If the board 20 is screwed to the lid member 40 (see FIGS. 5 (a) and 5 (b)), all the fastening parts 51 are converted into an openable state for illegal purposes, and the board box Even if 50 is opened, the screw must be removed in order to take out the game control board 20 from the lid member 40, so that the tampering work on the game control board 20 becomes more difficult, and the deterrence effect can be further enhanced. it can.

  In addition, in the gaming machine 1 according to the present embodiment, when the cover member 60 is properly attached to the board box 50, the cover member position restricting portion 45 that protrudes from the fastening portion forming wall 41 of the lid member 40 is covered. The main cover wall 61 of the cover member 60 can be introduced in an appropriate state from the arrangement relationship between the cover member position restricting portion 45 and the top portion 43b of the screwing portion 43. In a state where the introduction possible area is limited and the top portion 43b of the screwing portion 43 and the main cover wall 61 of the cover member 60 are separated, the cover member position restricting portion 45 becomes an obstacle, and the edge of the main cover wall 61 is It was made impossible to attach to the fastening part forming wall 41 of the lid member 40.

  That is, if the screw 44 is not tightened to the fastening part 51 to close it, the head of the screw 44 protrudes from the top part 43b of the screw fastening part 43, so that the cover member 60 is properly attached to the substrate box 50. Since the fixing means 70 in which the cover side overlapping portion 65 and the box side overlapping portion 34 overlap with each other cannot be formed, the one-way screw 71 cannot be fixed. Therefore, when the board box 50 is normally opened, it is possible to prevent a mistake that the cover member 60 is fixed to the board box 50 without tightening the screw 44 to the fastening portion 51. In addition, it is impossible to assist a fraudulent act in which a game clerk conspiring with an unauthorized player intentionally secures the cover member 60 to the board box 50 without tightening the screw 44 of the fastening portion 51.

  In this configuration example, the arrangement relationship between the cover member position restricting portion 45 and the top portion 43b of the screwing portion 43 and the structure for preventing the screw 44 from coming off at the screwing portion 43 prevent the cover member from being attached to the board box. The first mounting blocking means that can be converted into a mounting permission state that allows mounting and a mounting blocking state that prevents the cover member from being mounted on the board box ”is configured, so that the screw 44 serving as the fastening member is fastened. Although the openable state that is not fixed to the portion 51 is an attachment blocking state in which the cover member 60 cannot be attached to an appropriate position, a structure in which fixing by the fixing means 70 is impossible is adopted. Although it is possible to attach the cover member 60 to the substrate box 50 in an openable state in which the screw 44 is not tightened to the fastening portion 51, Be secured to Chakushudan 70 by the one-way screw 71 may be adopted a structure becomes impossible.

  Next, the game control device 7 ′ adopting a structure in which the fastening portion and the connector portion are covered with a cover member will be described in detail with reference to FIGS.

  In recent years, as fraud that has occurred in amusement stores, there is one that attaches a fraudulent board called a “hanging board” to a gaming machine. As an example of this “hanging board”, for example, an illegal signal is input from the hanging board to the game control device by interposing it in the signal line between the start port sensor provided on the game board and the game control board of the game control device. There is something that causes a big hit. To connect such a hanging board to a gaming machine, the connector of the start port sensor is pulled out from the connector part of the game control device, the connector is connected to the hanging board, and the connector provided on the cable from the hanging board Is connected to the connector of the game control device, the installation work time is short, and the “hanging board” to be attached is also miniaturized, so it is not easy to detect fraud due to the hanging board. .

  Therefore, in the game control device 7 ′ of the present configuration example, the connector portion is also covered with the cover member together with the fastening portion, and an illegal act of attaching a “hanging board” via the connector portion is suppressed. That is, a substantially rectangular game control board 120 on which various electronic / electrical parts and connectors are mounted is housed in a board box 150 made of a synthetic resin base member 130 and a lid member 140, and a stop provided on the board box 150 is provided.

  A plurality of board-side connectors 122... Provided on the game control board 120 are arranged in a line in a sliding direction (attachment / removal direction) of a cover member 160, which will be described later, and are attached to various wiring cords 180 extending from the electrical components. When the cover member 160 is attached to the board box 150 in a state where the cord-side connector 181 to be connected (for example, a female connector having a pin insertion hole) is connected to the board-side connector 122 (for example, a male connector having a connection pin). The various wiring cords 180 are led out to the outside through the slit-like wiring insertion space 161 provided in the cover member 160 (see FIG. 9C).

  Further, in the board box 150, for example, engagement portions 152, each including engagement receiving portions 131,... Provided on the base member 130 and engagement protrusions 141, provided on the lid member 140, are appropriately formed, and the base member is formed. When the base member 130 and the lid member 140 are slid in the relative engagement direction, the base member 130 and the lid member 140 are brought into an engagement state in which the base member 130 and the lid member 140 cannot be separated. The base member 130 and the lid member 140 return to the disengaged state where they can be separated.

  When the board box 150 containing the game control board 120 is brought into the engaged state by the detachable engaging portion 152, a plurality of fastening bosses 132 provided in a protruding manner at appropriate positions on the inner surface side of the base member 130 are covered. Since the fastening hole 132a provided in each fastening boss 132 and the fastening hole 142a provided in the fastening plate part 142 communicate with each other in proximity to or in contact with the fastening plate part 142 of the member 140, the fastening member The fastening plate 143 of the lid member 140 and the fastening boss 132 of the base member 130 can be fastened by the loose fastening screw 153. That is, in the present configuration example, the fastening hole 132a provided in the fastening boss 132 of the base member 130 and the fastening hole 142a provided in the fastening plate portion 142 of the lid member 140 cooperate with each other, so 151 (a closed state in which the lid member 140 and the base member 130 are fastened by the fastening member, an openable state in which the lid member 140 and the base member 130 can be opened by releasing the fastening by the fastening member, It is a fastening part that can be converted into).

  When the cover member 160 is properly attached to the board box 150, in addition to the fastening portion 151, the board-side connectors 122 ... of the game control board 120 and the cord-side connectors 181 ... connected to the board-side connectors 122 are provided. Covered by a cover member 160. At this time, a plurality of (for example, four) cover-side overlapping portions 162 provided on the cover member 160 and a plurality of (for example, four) box-side overlapping portions 143 provided on the lid member 140 overlap each other, and the fixing means 170. Configure.

When the one-way screw (not shown) that cannot be loosened when tightened is tightened from the fixing portion 162b to the fixing portion 143b, the one-way screw cannot be removed from the fixing portions 162b and 143b, so that the cover member 160 can be removed from the board box 150. Disappear. In addition, the cut portions 162a and 143a are portions that can be cut relatively easily by a cutting tool such as a nipper, and the cut portions 162a and 143a are cut while the cover side overlapping portion 162 and the box side overlapping portion 143 are overlapped. (When the fixing means 170 is destroyed), the fixing portions 162b and 143b fixed with the one-way screw are removed, and the cover member 160 can be removed from the substrate box 150.

  When the cover member 160 is attached to the board box 150 as in the game control device 7 ′ of this configuration example, the board side connectors 122... And the cord side connectors attached to the board side connectors 122 together with the fastening portions 151. 181.. Can be covered, and in order to perform an illegal act of interposing an illegal substrate or the like between the board side connector 122 and the cord side connector 181, the fixing means 170 is destroyed and the cover member 160 is removed from the board box 150. It is necessary to remove, and such an illegal act can be reliably grasped as a destruction history of the fixing means 170. Note that if a box opening history entry sheet 144a and a cover opening history entry sheet 144b are provided at appropriate positions (for example, the lid member 140) of the board box 150, and a regular opening history is entered in these at any time, an entry is required. From the number of broken fixing means 170, it is easy to determine that an unauthorized opening operation has been performed.

  However, since the cover member 160 that covers the fastening portion 151 is fixed to the board box 150 by the fixing means 170, when the structure in which the board-side connectors 122 of the game control board 120 are also covered by the cover member 160 is adopted, a new stand If the cord-side connector 181 is forgotten or mistaken at the time of replacement, the cord-side connector 181 cannot be reattached unless the fixing means 170 is broken and the cover member 160 is removed from the board box 150. It is. In particular, the number of fixing means 170 provided in the game control device 7 ′ is limited. If the fixing means 170 is completely destroyed, the cover member 160 cannot be attached, and the cover is required unless the police is present. If the member 160 cannot be removed, the police must be called each time. In view of such problems, a cover member 160 is attached to the game control device 7 ′ shown as the present configuration example unless the cord side connectors 181 are properly connected to all the board side connectors 122. Adopted a structure that can not. This will be described in detail below.

  First, the first slide portion 163a provided in a bent shape from the lower edge of the side surface portion where the cover side overlapping portion 162 is provided in the cover member 160 is moved so that the second slide portion 163b is opposed to the first slide portion 163a. The first and second slide portions 163a and 163b are inserted from the side end openings of the first slide guide recess portion 154a and the second slide guide recess portion 154b formed in the board box 150, and the mounting direction (in FIG. All the cord-side connectors 181... And the fastening portions 151 are covered with the cover member 160 by being slid to the back. At this time, as described above, the cover-side overlapping portion 162 and the box-side overlapping portion 143 overlap each other to form the fixing means 170 and can be fastened with a one-way screw.

  The first slide guide recess 154a in the board box 150 is, for example, a space formed between the first guide piece 145a provided in the lid member 140 and the game control board 120, and the first slide part of the cover member 160 The thickness is set to be approximately equal to or slightly wider than the thickness of 163a. On the other hand, the second slide guide recess 154b in the substrate box 150 is, for example, an empty space formed between the second guide piece 145b provided on the lid member 140 and the plurality of slide guide pieces 191 provided on the attachment restricting member 190. And is set to be approximately equal to or slightly wider than the thickness of the second slide portion 163b of the cover member 160.

  Therefore, when the attachment restricting member 190 is provided with the slide restricting pieces 192 between the slide guide pieces 191, and the attachment restricting member 190 is properly attached to the lid member 140, the slide restricting piece 192 is provided. Since the extending direction of the slide restricting piece 192 is inclined more than the extending direction of the slide guide piece 191 so as to gradually approach the second guide piece 145b from the base end portion to the projecting end, The separation distance between the piece 192 and the second guide piece 145b is narrower than the separation distance between the slide guide piece 191 and the second guide piece 145b, and the second slide portion 163b of the cover member 160 exceeds the slide restriction piece 192. Further, it is prevented from being inserted further into the back (see FIG. 9A).

  The attachment restricting member 190 is formed of elastic synthetic resin or the like and presses the attachment restricting member 190 with an appropriate pressing force so that the extending direction of the attachment restricting member 190 is the extending direction of the slide guide piece 191. And can be restored to the original tilted state when the pressing force is removed. Further, the slide restricting piece 192 of the attachment restricting member 190 is provided corresponding to each of the board side connectors 122 provided in the connector disposing region 121 of the game control board 120, and is a protruding end portion of each slide restricting piece 192. The connection determination unit 192a is in a state of being close to the board-side connector 122. For example, as shown in FIG. 7, when four board-side connectors 122... Are provided in the connector arrangement region 121 of the game control board 120, four slide restricting pieces 192. Five slide guide pieces 191... Adjacent to each slide restriction piece 192 are provided.

  Further, in this configuration example, the mounting portion 193 of the slide regulating member 190 is fitted and attached to the regulating member mounting portion 146 provided on the lid member 140, and the game control board 120 is enclosed and engaged with the base member 130. When the board box 150 is configured, the slide guide piece 191 of the slide regulating member 190 is brought into a state of approaching or abutting substantially in parallel with the electronic / electrical part mounting surface of the game control board 120, whereby the second guide piece 145b. The second slide guide recess 154b, which is a space between the slide guide piece 191 and the slide guide piece 191 ..., is prevented from becoming wider than the thickness of the second slide part 163b of the cover member 160, and the slide restriction piece 192 and the second slide guide piece 191 ... The second slide part 163b of the cover member 160 is prevented from passing between the guide piece 145b.

  In order to connect an appropriate cord side connector 181 to the board side connector 122 of the board box 150 including the slide restricting member 190 configured as described above, the connection pins 122a of the board side connector 122 are connected to the cord side connector 181. It is pushed so as to be inserted into the pin insertion hole (the direction indicated by the arrow B in FIG. 9A), and the locking claw of the locking portion 122b of the board-side connector 122 is locked in place on the cord-side connector 181. Press until it is done. At this time, the restriction release protrusion 181a that protrudes from an appropriate position on the side facing the second slide guide recess 154b of the cord-side connector 181 just contacts the connection determination part 192a of the slide restriction piece 192 of the slide restriction member 190, thereby controlling the game. By pressing the slide restricting piece 192 toward the electronic / electrical part mounting surface of the substrate 120, at least the surface facing the second guide piece 145b on the base end side of the slide restricting piece 192 is substantially the same as the slide guide piece 191. (See FIG. 9B).

  In this way, when the appropriate cord-side connector 181 is connected to the board-side connector 122, the restriction release protrusion 181a just contacts the connection determination part 192a of the slide restriction piece 192, and the slide restriction piece 192 is connected to the game control board. Since the pressure is applied toward 120, an empty space through which the second slide portion 163b of the cover member 160 can pass is secured between the slide regulating piece 192 and the second guide piece 145b, and the second slide portion 163b of the cover member 160 is secured. Is allowed to be inserted further beyond the slide restricting piece 192 (see FIG. 9C).

  That is, in the game control device 7 ′ of the present configuration example, the slide restricting member 190 attached to the lid member 140 and the second guide piece 145 b formed on the lid member 140 cooperate with each other, thereby “to the board box of the cover member”. The second attachment blocking means functions as a second attachment blocking means that can be converted into a mounting permission state that allows the mounting of the cover member and a mounting blocking state that prevents the cover member from being attached to the substrate box. If the cord-side connector 181 is not attached to the connector 122, it is converted into an attachment-blocking state, and if the cord-side connector 181 is attached to the board-side connector 122, it is converted into an allowable state. Therefore, the board-side connector 122 and the cord-side connector 181 If a fraudulent act with a fraudulent substrate or the like between them is performed, the second attachment blocking means converts to an attachment permitted state. To fry, it is impossible to attach the cover member 160 to the substrate box 150. Therefore, a fraudulent act such as a game clerk who conspires with an illegal player attaches the cover member 160 to the board box 150 in a state where the illegal board or the like is intentionally interposed between the board-side connector 122 and the cord-side connector 181. Assistance is also difficult.

  In the configuration of the slide regulating member 140 described above, if the appropriate cord-side connector 181 is attached to the board-side connector 122, the cover member 160 can be used even if the fastening portion 151 is not in the fastening state. Can be worn. Therefore, a configuration example in the case where the function as the first attachment blocking means employed in the above-described game control device 7 is also added to the game control device 7 ′ will be described based on FIG.

  In order to realize the function as the first and second attachment blocking means, the slide restricting member 190 ′ is provided with the fastening portion 151 (the fastening plate portion 142 of the lid member 140 on the back side of the connector disposing region 121. The slide restricting piece 194 provided on the slide restricting member 190 ′ is set so as to extend to a portion corresponding to the fastening hole 142 a of the fastening plate portion 142. That is, in order to fasten the fastening screw 153, which is a fastening member, from the fastening hole 142a of the lid member 140 to the fastening hole 132a of the base member 130, the fastening plate portion is secured from the fastening hole 194a of the slide regulating piece 194. A fixing screw 153 must be passed through the fixing hole 142a of 142 (see FIG. 10A).

  Since the slide restricting piece 194 is inclined in the extending direction like the slide restricting piece 192 provided corresponding to the board-side connector 122, the slide restricting piece 194 and the second guide piece 145b are separated from each other. The interval is narrower than the separation interval between the slide guide piece 191 and the second guide piece 145b, and the second slide portion 163b of the cover member 160 is prevented from being inserted further beyond the slide restricting piece 194. .

  On the other hand, when the fastening screw 153 is tightened from the fastening hole 194a of the slide restricting piece 194 to the fastening hole 142a of the fastening plate portion 142, the base end portion of the slide restricting piece 194 is mounted on the electronic / electrical parts of the game control board 120. The surface that is pressed against the surface and the outer surface of the fastening plate portion 142 and that faces at least the second guide piece 145b on the base end side of the slide restricting piece 194 is substantially flush with the slide guide piece 191 (FIG. 10B). See).

  In this way, if the fastening screw 153 is tightened from the fastening hole 194a of the slide restricting piece 194 to the fastening hole 142a of the fastening plate part 142 in the fastening part 151, the slide restricting piece 192 becomes the game control board 120. Since it is pressed toward the fastening plate portion 142, an empty space through which the second slide portion 163b of the cover member 160 can pass is secured between the slide restricting piece 194 and the second guide piece 145b. The second slide portion 163b is allowed to be inserted further beyond the slide restricting piece 194 (see FIG. 10C).

  That is, in the configuration example using the slide restricting member 190 ′, the slide restricting member having the slide restricting piece 194 extending to the portion corresponding to the fastening hole 142a of the fastening plate portion 142 to form the fastening hole 194a. 190 ′ and the second guide piece 145b formed on the lid member 140 cooperate to “allow attachment of the cover member to the substrate box and prevent attachment of the cover member to the substrate box. The first attachment blocking means functions as a “first attachment blocking means that can be converted into an attachment blocking state”, and the first attachment blocking means is in an installation blocking state in a disengageable state in which the fixing screw 153 is not fixed to the fixing portion 151. In the closed state in which the fastening screw 153 is fastened to the fastening portion 151, it is converted to a mounting permission state. , Prevent mistakes the left cover member 160 does not tighten the fastening screws 153 to the fastening part 151 thus fixed to the substrate box 150. In addition, it is impossible to assist a fraudulent act in which a game clerk conspiring with an unauthorized player does not intentionally tighten the fastening screw 153 to the fastening portion 151 and fixes the cover member 160 to the board box 150.

  The function as the first and second attachment blocking means described above is such that the slide restricting pieces 192 and 194 are attached to the electronic / electrical part mounting surface of the game control board 120 and the fastening plate part 142 like the slide restricting members 190 and 190 ′. , The cover member 160 is converted into a state in which the second slide part 163b of the cover member 160 can pass (attachment allowable state). However, the present invention is not limited to this, and other methods can be used as appropriate.

  For example, in the second attachment blocking means shown in FIG. 11, the same function as that of the slide restricting member 190 described above is realized by the attachment guide member 195 and the conversion member 196. The mounting guide member 195 is disposed on the board side connector 122 from the open side end (the end on the side close to or in contact with the game control board 120) of the mounting part 195a held by the guide member mounting part 147 of the lid member 140 ′. A second slide portion 195b that extends toward the portion and that allows the second slide portion 163b of the cover member 160 to pass between the slide guide portion 195b and the second guide piece 145b of the lid member 140 ′. A guide recess 154b is formed.

  On the other hand, the conversion member 196 includes a thin plate-like slide portion 196a, and is provided in a conversion member guide recess portion 195c provided for the slide guide portion 163b of the mounting guide member 195 so as to correspond to each of the placement portions of the board-side connector 122. By disposing the slide portion 196a, the attachment portion 196b provided at the free end portion of the slide portion 196a (the end portion capable of contacting the board-side connector 122) is prevented from attaching to the base portion 122c of the board-side connector 122. The state and the contact portion 196b can be converted into a mounting allowable state in which the contact portion 196b is separated from the base portion 122c of the board-side connector 122.

  A retaining end elastic portion 196c is provided at the holding end of the conversion member 196 (the end opposite to the free end), and the retaining elastic portion 196c is inserted into the conversion member holding empty portion 148 of the lid member 140 ′. When housed, the elastic force of the retaining elastic portion 196c generates a pressing force that causes the abutting portion 196b to abut against the base portion 122c of the board-side connector 122. Under normal conditions, the conversion member 196 is prevented from being attached by the retaining elastic portion 196c. (See FIG. 11A). An attachment restricting portion 196d that bulges toward the second guide piece 145b is provided at the holding end portion of the slide portion 196a of the conversion member 196. In the attachment blocking state, the attachment restricting portion 196d of the conversion member 196 covers the cover 196d. Since the depth (the width in the left-right direction in FIG. 11) of the second slide guide recess 154b is narrowed so as to prevent the member 160 from passing through the second slide portion 163b, the second slide portion 163b of the cover member 160 is converted. The insertion beyond the member 196 is further prevented.

  Further, the contact portion 196b of the conversion member 196 is provided with a pressure receiving portion 196e, and the pressure receiving portion 196e is pressed by the pressing portion 181b of the cord side connector 181 ′ (the portion that contacts the base portion 122c of the board side connector 122). Then, the conversion member 196 is converted into an attachment allowable state. That is, the connection pin 122a of the board-side connector 122 is pushed into the pin insertion hole of the cord-side connector 181 ′ (in the direction indicated by the arrow B in FIG. 11A). When the locking claw of the stopper 122b is pressed until it is locked in place on the cord-side connector 181, the contact portion is brought into contact by the pressure receiving portion 196e of the conversion member 196 that receives the pressing force of the pressing portion 181b of the cord-side connector 181 ′. A force in a direction separating 196b from the board-side connector 122 (a direction indicated by an arrow C in FIG. 11B) is generated, and the slide portion 196a and the mounting restricting portion 196d are resisted against the elastic force of the retaining elastic portion 196c. Moves in a direction away from the board-side connector 122 (see FIG. 11B).

  Thus, if the cord side connector 181 'is connected to the board side connector 122, the attachment restricting portion 196d of the conversion member 196 is pushed into the conversion member holding empty portion 148 of the lid member 140', so that the cover member The attachment restricting portion 196d of the conversion member 196 is retracted from the position where the second slide portion 163b of 160 is prevented from passing, and the second slide portion 163b of the cover member 160 is inserted further beyond the conversion member 196. (See FIG. 11C).
