JP 2003-154110 A

  By the way, when the control board is accommodated in the board box, a connection opening is formed in the board box, and the receptacle connector and the plug connector are connected through the connection opening. However, in this case, a gap may be formed between the peripheral edge of the connection opening of the board box and the connector, and a wire or the like enters the board box from the gap to cause a malfunction to the control board. There is a risk of misconduct. In particular, if there are many electrical devices that are electrically connected to the control board, the number of gaps may increase accordingly. In this case, there is a concern that fraudulent acts such as wire intrusion into the board box are likely to be performed. The above-described problems are not limited to pachinko machines, but also apply to other gaming machines such as slot machines.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a gaming machine capable of suppressing an illegal act such as a wire or the like entering a board box.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to the means to respond | correspond as needed are added.

Means 1. A control board to which a plurality of electrical devices are connected via a connector;
A substrate box comprising a base member and a cover member and encapsulating the control substrate in an accommodated state;
Sealing means for connecting the base member and the cover member;
A gaming machine in which a predetermined trace is formed when the encapsulated state of the board box is released,
The board box has a connection opening for connector connection,
A receiving connector provided on the control board;
An insertion side connector for connecting an electrical device to the control board,
In the connecting direction of the insertion-side connector with respect to the receiving-side connector, the receiving-side connector has a tip portion at the same height as the inner surface of the board box at the periphery of the connection opening, or from the inner surface of the board box Is also located outside the substrate box,
A gaming machine, wherein one receiving-side connector and a plurality of insertion-side connectors are connected.

  According to the means 1, one control board and a plurality of electric devices are connected by connecting a plurality of insertion side connectors to one receiving connector provided on the control board. Therefore, when providing the same number of receiving side connectors as the number of all electrical devices electrically connected to one control board (when receiving side connectors are provided in one-to-one correspondence with plug-in side connectors) ), The number of receiving-side connectors provided on the control board can be reduced. Thus, the number of connection openings formed in the board box can be reduced by combining the receiving connectors connected to the plurality of plug-in connectors as one receiving connector. For this reason, the location where the clearance gap which can insert a wire etc. between the peripheral part of the opening part for connection of a substrate box and a connector can arise can be reduced. As a result, it is possible to suppress an illegal act such as intruding a wire or the like into the board box to cause the control board to malfunction.

  In addition, by collecting the receiving connectors connected to the plurality of plug-in connectors as one receiving connector, the space required for connector connection on the control board can be reduced, and the control board can be simplified and Miniaturization can be achieved. In addition, when the number of electrical devices electrically connected to the control device (the number of plug-in side connectors) increases or the number of cables connected to the plug-in side connectors increases, the size of the control board increases. These connection spaces can be ensured on the control board without incurring the increase in the size. In addition, since a plurality of plug-in connectors are gathered in one place, when the plug-in connector is provided at one end of the cable, the cable extends from all over the back of the gaming machine and The risk that the back surface becomes complicated can be suppressed.

  In addition, for example, when a plurality of receiving connectors are provided close to each other due to installation space or the like, a connection opening that encloses the receiving connectors together must be formed. There is. In this case, if the receiving connector is separated from the receiving connector adjacent to the receiving connector, the wire or the like is inserted into the board box from the gap between the adjacent receiving connectors through the connection opening. There is a risk of fraudulent activities such as intrusion. In particular, the more the number of receiving connectors corresponding to one connection opening, the more gaps are formed between adjacent receiving connectors, and this is a fraudulent act that causes a wire or the like to enter the board box. May be easier to do. In this regard, according to the present means, by reducing the number of receiving side connectors necessary for connecting a plurality of insertion side connectors to the control board, the number of places where a gap can be generated between the receiving side connectors is reduced. Eventually, it can be lost. As a result, it is possible to suppress an illegal act of causing a wire or the like to enter the board box through a gap between adjacent receiving connectors via the connection opening.

  Further, according to this means, the distal end portion of the receiving connector is positioned at the same height as the inner surface of the substrate box at the periphery of the connection opening, or outside the substrate box than the inner surface of the substrate box. Yes. For this reason, the receiving side connector can be brought into a substantially abutting state with respect to the peripheral edge portion of the connection opening of the substrate box, and a gap in which a wire or the like can be inserted into the substrate box at the substantially abutted portion. Can be eliminated.

  In this means, it is intended that a plurality of insertion side connectors can be directly connected to one receiving side connector. As a configuration for connecting a plurality of cables connected to different electrical devices to one receiving connector, in addition to the configuration of this means, for example, a relay terminal to which a plurality of plug-in connectors can be connected A plurality of cables connected to different electrical devices, and a structure for connecting one receiving-side connector and a plurality of insertion-side connectors via the relay terminal portion. The structure etc. to connect are mentioned. However, in the former case, there is a possibility that it takes time and cost to provide a separate relay terminal portion. In the latter case, it may take time to specify in which cable the disconnection has occurred. In this respect, according to the present means, since a plurality of plug-in connectors are directly connected to one receiving connector, these problems can be avoided. In addition, when the latter configuration is adopted, even if one of the cables is disconnected, it is assumed that all the cables and the plug-in side connector must be replaced. According to the configuration of the means, it is only necessary to replace the broken cable and the plug-in connector individually corresponding to the cable, so that resource saving can be achieved.

  From the standpoint of preventing fraud as described above, it is desirable that there is no gap between the peripheral edge of the connection opening of the board box and the connector, but there is a slight margin in the connection opening. Otherwise, it may be difficult or impossible to insert the connector into the connection opening. In other words, the term “no gap” means “there is only a gap that can prevent the wire or the like from entering the board box and does not hinder the connector insertion workability”.

  “Electrical equipment” includes detection means such as sensors (detection switches), electric members such as display devices, lamps and speakers, and “other control boards”, and one control board via a cable. Examples of the plurality of electrical devices to be connected include any of detection means, electrical members, other control boards, or a combination thereof.

That is, by connecting a plurality of receiving-side connectors that have been provided close to each other as one receiving-side connector, a connection opening that collectively surrounds the plurality of receiving-side connectors is eliminated. As a result, it is possible to eliminate a situation where a plurality of receiving-side connectors and a plurality of corresponding insertion-side connectors are connected through one connection opening, and the receiving connector adjacent to the receiving-side connector can be eliminated. It is possible to avoid a possibility that a gap into which a wire or the like can be inserted is formed between the side connector and the side connector. Further, since the connection opening can be formed in accordance with the outer peripheral shape of the receiving connector, a wire or the like is caused to enter the board box between the receiving connector and the peripheral edge of the connection opening of the board box. It is possible to eliminate such a gap. Accordingly, it is possible to prevent an illegal act such as causing a wire or the like to enter the board box from between the adjacent receiving connectors through the connection opening.

  Furthermore, since the possibility of manufacturing errors increases as the number of members increases, for example, when forming connection openings in accordance with the outer peripheral shape of a plurality of insertion side connectors, The possibility that a gap that allows insertion of a wire or the like between the peripheral edge of the opening and the connector will be increased.

It becomes. Therefore, even after the adjacent insertion side connectors are engaged with each other, the insertion side connector can be relatively easily detached from the insertion side connector adjacent to the insertion side connector. For this reason, for example, it can be identified relatively easily in which cable the disconnection has occurred, as compared with a case where once the adjacent plug-in connectors are once engaged, they cannot be detached again. In addition, if the plug-in connector in the engaged state cannot be removed, the cable connected to one of the plurality of plug-in connectors connected to one receiving connector has been disconnected. Even if it is a case, the case where all the cables and the insertion side connector must be replaced is assumed. In this respect, according to the present means, it is only necessary to remove and replace the broken cable and the plug-in connector corresponding to the cable, so that resource saving can be achieved. As a result, effects such as excellent maintainability and reusability are achieved.

  Mean 7 At least one of the plurality of insertion-side connectors is provided with a locking portion that is locked to a locked portion provided in the receiving-side connector, and the locking portion is connected to the locked portion.

In addition, a pair of notches 496 and 497 that form recesses 495 are formed at the upper surface side (upper side in FIG. 8) boundary between the plug housing 422b and the plug housing 422c. On the other hand, as shown in FIG. 6, the side wall 415 of the receptacle housing 412 is provided with a recessed portion 418 that is recessed inward in accordance with the concave portions 491 and 495 of the plug connector 403.

  Next, a procedure for connecting the receptacle connector 402 and the plug connectors 403a to 403c configured as described above will be described.

  First, as shown in FIG. 9, the first plug connector 403a is positioned on the distal end side of the second plug connector 403b. Then, the first plug connector 403a is moved in the direction of the arrow in the figure so as to slide the engagement surface F1 and the engagement surface F3. More specifically, the pair of engagement ribs 455 of the second plug connector 403b are inserted through the pair of second engagement grooves 431 of the first plug connector 403a (as shown in FIG. The inner surface of the second rib 434 is brought into contact with the inner surface). Accordingly, the first plug connector 403a is guided along the second engagement groove 431, and the relative movement of the first plug connector 403a with respect to the second plug connector 403b can be performed relatively easily. Thereafter, the first plug connector 403a is moved until the second protrusion 436 contacts the end of the engagement rib 455 and the step 454 of the first engagement piece 451 contacts the first protrusion 437. Thus, the engagement between the first plug connector 403a and the second plug connector 403b is completed.

  Subsequently, the third plug connector 403c is positioned on the distal end side of the second plug connector 403b. Then, the third plug connector 403c is moved in the direction of the arrow in FIG. 9 so as to slide the engagement surface F5 and the engagement surface F4.

Thereby, the second plug connector 403b is guided along the first engagement groove 462 and the second engagement groove 461, and the relative movement of the third plug connector 403c with respect to the second plug connector 403b is relatively easy. It can be carried out. Thereafter, the third plug connector until the end of the engagement rib 473 contacts the second protrusion 466 and the locking claw 472 of the second engagement piece 471 contacts the step 468 of the first protrusion 467. By moving 403c, the engagement between the third plug connector 403c and the second plug connector 403b is completed. Note that the engagement between the third plug connector 403c and the second plug connector 403b may be performed before the engagement between the first plug connector 403a and the second plug connector 403b.

  Next, as shown in FIG. 6, the distal end portions of the plug connectors 403 a to 403 c that are engaged together are arranged opposite to the receptacle housing 412. Then, the operating portions 443 and 483 are picked so that the locking portions 441 and 481 are pressed against the outer surfaces F2 and F6, and the plug connectors 403a to 403c are inserted into the receptacle housing 412 in this state. Then, as shown in FIG. 7, the plug connectors 403a to 403c are pushed in until the locking claws 444 and 484 of the locking portions 441 and 481 are locked to the corresponding locking projections 417, respectively. The connection between the connectors 403a to 403c and the receptacle connector 402 is completed.

  When the plug connectors 403a to 403c are detached from the receptacle connector 402, first, the operating portions 443 and 483 are picked to release the locked state between the locking portions 441 and 481 and the locking convex portion 417. By pulling the plug connectors 403a to 403c in this state, the plug connectors 403a to 403c can be detached at a time.

  Further, when the first plug connector 403a is detached from the second plug connector 403b, first, the second side portion 453 is pressed so as to bring the first engagement piece 451 toward the engagement surface F3, and the first plug The engagement state between the connector 403a and the second plug connector 403b is released. In this state, the first plug connector 403a can be detached from the second plug connector 403b by moving the first plug connector 403a relative to the second plug connector 403b in the direction opposite to the arrow in FIG. it can.

  Further, when the third plug connector 403c is detached from the second plug connector 403b, first, the second engagement piece 471 is pressed so as to bring the second engagement piece 471 toward the engagement surface F5, and the second engagement piece 471 is pressed. The engagement state between the plug connector 403b and the third plug connector 403c is released. In this state, the third plug connector 403c can be detached from the second plug connector 403b by moving the third plug connector 403c relative to the second plug connector 403b in the direction opposite to the arrow in FIG. it can.

  As described above in detail, in the present embodiment, the three plug connectors 403a to 403c are connected to one receptacle connector 402, whereby the payout control board, the special display device 43, and the main board 261a are connected. A RAM erase switch circuit 543 is electrically connected. Therefore, compared with the case where the same number of receptacle connectors as the number of all electrical devices electrically connected to the main board 261a are provided (when the receptacle connectors are provided in one-to-one correspondence with the plug connectors), The number of receptacle connectors provided on the main board 261a can be reduced. As described above, by combining the receptacle connectors connected to the plurality of plug connectors 403a to 403b as one receptacle connector 402, the number of connection openings W formed in the board box 263 can be reduced. For this reason, it is possible to reduce the number of places where a gap in which a wire or the like can be inserted is generated between the peripheral edge of the connection opening W1 of the board box 263 and the receptacle connector 402. As a result, it is possible to suppress an illegal act such as causing a wire or the like to enter the board box 263 and causing the main board 261a to malfunction.

  Further, by combining the receptacle connectors connected to the plurality of plug connectors 403a to 403b as one receptacle connector 402, a compact receptacle connector necessary for connecting the plurality of plug connectors 403a to 403b to the main board 261a. Can be achieved. For example, as shown in FIG. 13, when receptacle connectors 702a, 702b, 702c and plug connectors 703a, 703b, 703c are provided in a one-to-one correspondence, even if adjacent plug connectors 703a, 703b, 703c are provided. Even if they are brought into contact with each other, the wall portions 715 of the receptacle connectors 702a, 702b, 702c exist between the plug connectors 703a, 703b and between the plug connectors 703b, 703c. On the other hand, in this embodiment, the wall part which separates adjacent plug connectors can be omitted. Therefore, the space required for connector connection on the main board 261a can be reduced, and the main board 261a can be simplified and downsized. Further, when the number of electrical devices (number of plug connectors) electrically connected to the main board 261a is increased or the number of cables connected to the plug connectors is increased, the main board 261a is increased in size. These connection spaces can be secured on the main board 261a without incurring.

  In addition, since the three plug connectors 403a to 403c are collected in one place, the cables C1 to C3 can be gathered together. Therefore, it is possible to suppress the possibility that the cable extends from the back of the pachinko machine 10 and the back of the pachinko machine 10 becomes complicated.

  Further, for example, as shown in FIG. 13, when a plurality of receptacle connectors 702a, 702b, and 703c must be provided close to each other due to the installation space or the like, the plurality of receptacle connectors 702a, 702b, and 703c are provided. May be inevitably formed to form a connection opening W2. In this case, if the receptacle connectors 702a, 702b, and 703c are separated from each other, gaps are generated between the receptacle connector 702a and the receptacle connector 702b, and between the receptacle connector 702b and the receptacle connector 702c. There is a risk that an illegal act of causing a wire or the like to enter the substrate box 263 from the gap through the portion W2.

  In this regard, according to the present embodiment, the receptacle connectors necessary for connecting the plurality of plug connectors 403 a to 403 c to the main board 261 a are combined into one as the receptacle connector 402. That is, by connecting a plurality of receptacle connectors that have been provided close to each other as one receptacle connector, it is possible to eliminate a connection opening that collectively surrounds the plurality of receptacle connectors. Therefore, by projecting one receptacle connector 402 connected to the plurality of plug connectors 403a to 403c from the board box 263 through the connection opening W1 formed in accordance with the outer periphery of the receptacle connector 402, the receptacle A gap between the connector 402 and the peripheral edge of the connection opening W1 of the board box 263 can be eliminated. As a result, it is possible to prevent an illegal act such as causing a wire or the like to enter the board box 263 through the connection opening W1.

  Further, for example, when the connection opening W1 is formed in accordance with the outer peripheral shape of the plug connectors 403a to 403c, when the plug connectors 403a to 403c are inserted and removed, the peripheral edge of the connection opening W1 of the board box 263 is There is a risk of being damaged and deforming or chipping. Furthermore, since the possibility of manufacturing errors increases as the number of members increases, the connection opening of the board box 263 is formed when the connection opening W1 is formed in accordance with the outer peripheral shape of the plug connectors 403a to 403c. The possibility that a gap will be formed between the W1 peripheral edge and the plug connectors 403a to 403c is increased. In this regard, in the present embodiment, since the connection opening W1 is formed in accordance with the outer peripheral shape of one receptacle connector 402, the above-described fear can be suppressed.

  In addition, plug connectors 403 a to 403 c are directly connected to the receptacle connector 402. For this reason, for example, compared with the case where the receptacle connector 402 and the plug connectors 403a to 403c are connected via a separate member (relay terminal portion), labor and cost required for providing the separate member can be saved. Can do.

  In the present embodiment, the first plug connector 403a and the second plug connector 403b are engaged, and the second plug connector 403b and the third plug connector 403c are engaged. In this manner, the three plug connectors 403a to 403c can be attached and detached at a time by engaging adjacent plug connectors. Further, the stability of the connection state between the receptacle connector 402 and the plug connectors 403a to 403c can be improved.

  Furthermore, the engagement of the plug connectors 403a to 403c is performed by relatively moving adjacent plug connectors in a direction along the longitudinal direction, and grooves provided in one plug connector (second engagement grooves 431 and 461). The ribs (engagement ribs 455 and 473) provided on the other plug connector are inserted through the plug connector. Accordingly, adjacent plug connectors come into contact with each other, and there is almost no gap between the plug connectors. For this reason, the space required for connector connection on the main board 261a can be more reliably reduced.

  Further, by operating the first engagement piece 451 and the second engagement piece 471, the engagement between the first engagement piece 451 and the second engagement piece 471 and the first convex portions 437 and 467 can be released. it can. Therefore, even after the adjacent plug connectors are engaged with each other, the adjacent plug connectors can be separated relatively easily. For this reason, for example, it is relatively easy to determine which of the cables C1 to C3 has a disconnection, compared to the case where a configuration in which adjacent plug-in connectors are once engaged and cannot be detached again is employed. Can be specified. Further, if the plug connectors 403a to 403c in the engaged state cannot be detached, even if any of the cables C1 to C3 is disconnected, all the cables C1 to C3 and the plug connector 403a are used. It is also assumed that ˜403c must be replaced. In this regard, in the present embodiment, it is only necessary to remove and replace the cable C1 to C3 and the plug connectors 403a to 403c that are disconnected, and the plug connector corresponding to the cable, thereby saving resources. be able to. As a result, effects such as excellent maintainability and reusability are achieved.

  In addition, the locking portions 441 and 481 (locking claws 444 and 484) provided on the plug connectors 403a and 403c are locked to the locking projections 417 provided on the receptacle connector 402. As a result, the plug connectors 403a to 403c can be prevented from coming off, and the connected state can be stabilized. In addition, it is possible to grasp that the plug connector 403 is securely connected to the receptacle connector 402 by locking the locking portions 441 and 481 to the locking projection 417.

  Further, as described above, since the adjacent plug connectors are engaged with each other, only the locking portions 441 and 481 are provided on the first plug connector 403a and the third plug connector 403c, respectively. All the plug connectors 403a to 403c can be securely locked. As described above, since the number of the locking portions is small, the shapes of the plug connectors 403a to 403c and the receptacle connector 402 can be simplified.

  In addition, the control board (main board 261a and the like) is provided with a plurality of receptacle connectors. In general, however, the connection opening W is formed in view of the relative position shift between the receptacle connectors due to manufacturing errors or the like. It is formed slightly larger than the outer peripheral shape of the receptacle housing. In particular, when the number of receptacle connectors provided on the control board is large, it is necessary to form a larger connection opening. In this case, there is a risk that a gap may be created in which a wire or the like can be inserted into the substrate box 263. In this regard, according to the present embodiment, the number of receptacle connectors can be reduced, so that the above-described problem can be suppressed.

  As mentioned above, this invention is not limited to the said embodiment at all, and it cannot be overemphasized that it can implement with a various form, unless it deviates from the meaning of this invention.

  (A) In the above embodiment, the plug connectors 403a to 403c connected to the payout control board, the special display device 43, and the RAM erase switch circuit 543 are connected to the receptacle connector 402 via the cables C1 to C3. A plug connector connected to another electrical device that is electrically connected to the main board 261 a may be connected to the receptacle connector 402.

  Further, in the above-described embodiment, only in the electrical connection configuration of the main board 261a, the payout control board, the special display device 43, and the RAM erase switch circuit 543, a plurality of plug connectors are connected to one receptacle connector. The main board 261a and other electrical devices are electrically connected, and other control boards such as a sub control board (for example, a control board having a CPU) and the electrical equipment The above characteristic configuration may also be adopted in the electrical connection configuration.

  (B) The configuration (engagement means) for engaging adjacent plug connectors in the above embodiment is not particularly limited. For example, the first engagement piece 451, the second engagement piece 471, and the first projections 437 and 467 are omitted, and the adjacent plug connectors can be relatively moved in at least one direction even when they are engaged. Also good.

  For example, the extending direction of the second engagement grooves 431, 461 and the like provided along the longitudinal direction of the plug connectors 403a to 403c in the above embodiment is a direction orthogonal to the longitudinal direction of the plug connectors 403a to 403c, It is good also as a structure by which engagement is performed by relatively moving adjacent plug connectors to the direction orthogonal to the said longitudinal direction.

  For example, a protrusion is provided on one of the engaging surfaces to be engaged with each other, a hole in which the protrusion can be inserted is provided on the other, and adjacent plug connectors are moved relative to each other in the normal direction of the engaging surface. It is good also as a structure by which a combination is performed. In addition, it is good also as a structure which eliminates an engaging means and attaches each plug connector 403a-403c to the receptacle connector 402 each separately. In this case, it is desirable to provide a pair of locking portions that are locked to the receptacle connector 402 (locking convex portion 417) for each of the plug connectors 403a to 403c. Further, even in the connected state to the receptacle connector 402, adjacent plug connectors do not have to be in contact with each other.

  (C) In the above-described embodiment, three plug connectors 403a to 403c are connected to one receptacle connector 402 in a horizontal row, but the configuration is not particularly limited to this. For example, four plug connectors may be connected to one receptacle connector 402. Further, the first plug connector 403a and the second plug connector 403b may be arranged side by side, and the second plug connector 403b and the third plug connector 403c may be arranged vertically.

  (D) In the above embodiment, among the plug connectors 403a to 403c, the first plug connector 403a and the third plug connector 403c are provided with the locking portions 441 and 481, respectively. It is not limited to. For example, the second plug connector 403b may be provided with a pair of upper and lower (upper and lower in FIG. 8) locking portions. Also in this case, since the adjacent plug connectors are engaged with each other, all the plug connectors 403a to 403c can be reliably locked with respect to the receptacle connector 402. Of course, all plug connectors 403a to 403c may be provided with locking portions. Further, the locking portion may be locked to the inner surface of the substrate box 263. Further, the locking portion itself can be omitted.

  (E) In the above embodiment, identification information may be attached to the plug connectors 403a to 403c and the receptacle connector 402. For example, identification information such as “A-1”, “A-2”, and “A-3” is attached to the upper surfaces of the plug connectors 403a to 403b, and identification information such as “A” is attached to the upper surface of the receptacle connector 402. Also good. In this case, by visually recognizing the identification information, which plug connector is adjacent to the predetermined plug connector, and which surface of the predetermined plug connector corresponds to which surface of the adjacent plug connector ( In addition, it is possible to clearly recognize to which receptacle connector these plug connectors are connected. As a result, the arrangement configuration of the plug connector connected to the receptacle connector can be grasped instantaneously, and the connection workability can be improved. Further, for example, at least a part of the engagement surface F2 is yellow, at least a part of the engagement surface F3 is yellow, at least a part of the engagement surface F4 is blue, at least a part of the engagement surface F5 is blue, a plug housing The same effect can also be achieved by setting the upper surfaces of 422a to 422c to red and the upper surface of the corresponding receptacle housing 412 to red. In this case, the colored part corresponds to the identification information. Further, for example, the engagement surface F2 is fitted with a triangular groove, the engagement surface F3 is fitted with a triangular rib that fits into the triangular groove, the engagement surface F4 is fitted with a semicircular groove, and the engagement surface F5 is fitted with the semicircular groove. Semi-circular ribs may be provided. In this case, a part having a characteristic shape such as the groove or the rib corresponds to the identification information. Of course, a site characterized by a combination of the above-described coloring, outer shape, mark (mark by marking, Braille, etc.), etc. can also be used as identification information.

  (F) In the above embodiment, a closing member that covers at least the space between the receptacle housing 402 and the connection opening W1 may be provided. In this case, an illegal act of inserting a wire or the like from the connection opening W1 can be more reliably prevented. Moreover, according to the said embodiment, since the number of the opening parts W for connection can be reduced, even if it is a case where a closure member is provided as mentioned above, a effort and cost can be suppressed. The closing member may be extended from the receptacle housing 402 or the connector housings 403a to 403c, or may be provided separately.

  (G) In the above embodiment, the receptacle connector 402 includes the pin contact 411 and the plug connectors 403a to 403c include the socket contacts 421a to 421c. However, the receptacle connector 402 includes the socket contact, and the plug connectors 403a to 403c include A pin contact may be provided. However, in this case, the plug connector housing is inserted between the socket contact that contacts the pin contact of the predetermined plug connector and the socket contact that contacts the pin contact of the plug connector adjacent to the predetermined plug connector. A gap is required to make it happen. That is, the shape of the receptacle connector 402 may be complicated. Accordingly, it is desirable that the receptacle connector 402 includes the pin contacts 411 and the plug connectors 403a to 403c include the socket contacts 421a to 421c as in the above embodiment.

  (H) In the above embodiment, the receptacle connector connected to the plug connectors 403a to 403c through one connection opening W1 is configured as one receptacle connector 402. For example, the plug connectors 403a and 403b There may be a configuration in which there is one composite receptacle connector connected to and a single receptacle connector connected to the plug connector 403c. In this case, the space on the main board 261a necessary for connecting at least the plug connectors 403a and 403b to the main board 261a can be reduced. Further, for example, as compared with the case where two receptacle connectors are provided corresponding to the plug connectors 403a and 403b individually, the wire or the like enters the substrate box 263 through the gap between the adjacent receptacle connectors through the connection opening. Fraudulent acts such as

  The composite receptacle connector and the single receptacle connector may be separated from each other, but they are preferably in contact with each other from the viewpoint of fraud prevention. Further, from the viewpoint of fraud prevention and space saving, as in the above embodiment. More preferably, the receptacle connector connected to the plug connectors 403 a to 403 c is configured as one receptacle connector 402.

  (I) In the above embodiment, the front end side of the receptacle housing 412 protrudes to the outside of the substrate box 263 through the connection opening W1, but the invention is not limited to such a configuration. It suffices if there is no gap in which a wire or the like can be inserted between 412 and the peripheral edge of the connection opening W1 of the board box 263. For example, the front end side of the receptacle housing 412 is at the same height as the inner surface of the board box 263 in the connection direction of the plug connectors 403a to 403c, and is substantially in contact with the peripheral edge of the connection opening W1 of the board box 263. It is good also as composition which becomes.

  (J) In the above embodiment, the connection opening W1 and the receptacle connector 402 correspond one-on-one, but the present invention is not particularly limited to such a configuration. For example, as shown in FIGS. 11 and 12, one connection opening W3 may be formed corresponding to a plurality of (two in FIG. 11) receptacle connectors 402a and 402b. However, as shown in the figure, at least one of the two receptacle connectors 402a and 402b (the receptacle connector 402a in FIGS. 11 and 12) is connected to the plurality of plug connectors 403a and 403b. In this case, for example, as shown in FIG. 13, the number of gaps formed between adjacent receptacle connectors is reduced as compared with the case where three receptacle connectors are provided in one-to-one correspondence with the plug connectors 703a to 703c. be able to. As a result, it is possible to suppress an illegal act of causing a wire or the like to enter the board box 263.

  (K) You may implement as a pachinko machine etc. of a different type from the said embodiment. For example, once a big hit, a pachinko machine that raises the expected value of the big hit until a big hit state occurs (for example, two times or three times) including that (for example, a two-time right item, a three-time right item) May also be implemented. Further, it may be implemented as a pachinko machine that enters a special gaming state on the condition that a game ball is awarded in a predetermined area after the big hit symbol is displayed. Furthermore, the present invention can be applied to a pachinko machine called a blade. In addition to pachinko machines, the present invention can also be implemented as various game machines such as an arrangement ball machine or a sparrow ball similar to it. However, these gaming machines are equipped with a variable display device such as a liquid crystal display device or a dot matrix display device.

  (L) As a gaming machine other than a pachinko machine, it can of course be implemented as a slot machine as a swivel type gaming machine equipped with an auxiliary display device (liquid crystal display device, dot matrix display device) as a variable display device. The slot machine includes a rotating body with a plurality of symbols. For example, when a coin is inserted and the operating lever is operated in a state where the symbol effective line is determined, the symbol fluctuates, and the stop button It is a well-known thing that the symbol is stopped by operating. In this case, the auxiliary display device displays various effects as the rotating body rotates.

  Moreover, you may implement as a game machine which the pachinko machine and the slot machine united. As a specific example, an identification information string composed of a plurality of identification information (specifically, a reel and identification information is a symbol attached to the reel) is variably displayed (specifically, a rotation of the reel). And a variable display means for finally stopping and displaying the identification information. The fluctuation of the identification information is started due to the operation of the start operation means (for example, the operation lever), and the stop operation means (for example, the stop button) is operated. Due to the fact that the variation of the identification information is stopped due to the elapse of a predetermined time, a special gaming state generating means for generating a special gaming state advantageous to the player based on the lottery result made at that time is provided as a game medium. In addition to using game balls, a predetermined number of game balls are required at the start of variation of the identification information, and many game balls are paid out when a special game state occurs.
