  Accordingly, in the illustrated embodiment, the front cover member 510 is provided with a front side guide portion 601 that also serves as the first guide portion 6011 and the third guide portion 6013, and the second cover portion 602 and the fourth guide portion 602 are provided on the rear cover member 520. A rear side guide portion 602 that also serves as the guide portion 6024 is provided. In the following description, the front-side guide unit 601 and the rear-side guide unit 602 including the first guide unit 6011 to the fourth guide unit 6024 are simply referred to as guide units.

  Specifically, the front cover member 510 and the rear cover member 520 are respectively provided with a front-side guide portion 601 and a rear-side guide portion 602 formed when they are integrated with each other. Further, guide holes 651 and 652 are provided in the respective guide portions 601 and 602, respectively.

  Therefore, for example, in the embodiment shown in FIGS. 5 to 7, a guide portion 601 that bulges upward is provided on the upper edge portion of the front cover member 510, that is, the upright piece 5931 on the upper side, and the guide portion 601 has a lateral side. Guide holes 651 are arranged side by side in the direction. On the other hand, the rear cover member 520 is provided with a guide portion 602 in a bulging shape at a position corresponding to the guide portion 601 of the front cover member 510, that is, on the rising piece 5932 on the upper side, and the front cover member 510. Corresponding to the guide hole 651, a guide hole 652 is opened.

  In this embodiment, the guide hole 651 is formed in a holding portion 610 provided in the guide portion 601 as shown in FIG. 6, and the guide portion is connected via the connecting portion 611 by the holding portion 610. Contact 601. That is, the holding portion 610 provided with the guide hole 651 is independent of the opening portion formed in the guide portion 601 except for the connecting portion 611. Then, when opening the front cover member 510 and the rear cover member 520 integrated as described later, the connecting portion 611 is cut.

  Therefore, as described above, when the front cover member 510 and the rear cover member 520 are combined using the assembly connecting portion 531 and the assembly locking portion 532, the guides provided in the respective guide portions 601 and 602 are provided. The holes 651 and 652 communicate with each other to form one guide hole 650 (see FIG. 7).

  The sealing means and the case fixing means are formed when the front cover member 510 and the rear cover member 520 are integrated, and are provided in the front cover member 510 and the rear cover member 520, respectively, and when both are combined Function.

  Therefore, a sealing member is configured by attaching a coupling member 620 (hereinafter also referred to as a safety lock pin 620) that connects the integrated guide portions 601 and 602 to each other in an inseparable manner in the guide holes 651 and 652. To do. For example, as illustrated in FIG. 6, the coupling member 620 includes a flange portion 622 at the upper end of the support portion 621 and a locking portion 623 at the lower end. Further, a hollow portion 624 is provided on the side surface of the support portion 621. Further, in the embodiment shown in FIG. 6, two coupling members 620 are connected by a connecting member 625.

  Next, the connecting member 620 will be described in detail. The coupling member 620 that is a safety lock pin includes a support portion 621, a flange portion 622 provided at one end of the support portion 621, and a guide portion 601 and 602 provided at the other end of the support portion 621. The locking portion 623 to be locked is integrally formed of synthetic resin, and is integrally formed via the other coupling member 620 and the connecting member 625 as described above.

  The support part 621 has a prismatic cross section, for example, and a flange 622 having an elliptical cross section, for example, is connected to the upper end of the prism. A tool insertion groove 626 into which a tool such as a driver can be inserted is formed on the upper surface of the flange portion 622.

  On the other hand, a pair of locking portions 623 formed at the lower end of the support portion 621 extends diagonally upward from both ends in the longitudinal direction. The locking portion 623 can be elastically deformed, and when inserted into the guide holes 651 and 652, the engagement portion 623 can reduce the diameter and pass through the guide holes 651 and 652. Then, after passing through the guide holes 651 and 652, it returns to its original shape and expands, and engages with the edges of the guide holes 651 and 652 (see FIG. 7).

  Therefore, once the coupling member 620 as a safety lock pin is attached to the guide holes 651 and 652 and the front cover member 510 and the rear cover member 520 are once integrated, the locking portion 623 is attached to the edge of the guide hole 652. Because of the locking, the coupling member 620 cannot be pulled out and functions as a sealing means.

  The guide portions 601 and 602 are provided with insertion holes 630 for attaching the caulking pins 660 constituting the case fixing means. The insertion hole 630 is formed by combining the front cover member 510 and the rear cover member 520. For example, as shown in FIG. 7, the insertion hole 632 on the rear cover member 520 side and the front cover are formed. The insertion hole 631 on the member 510 side is configured to communicate with each other. In FIG. 7, the guide section provided with the insertion hole 650 for inserting the coupling member 620 and the guide section provided with the insertion hole 630 for inserting the caulking pin 660 have different cutting surfaces. That is, actually, the coupling member 620 is inserted in the vertical direction, and the caulking pin 660 is inserted in the front-rear direction.

  As shown in FIG. 7, for example, as shown in FIG. 7, the caulking pin 660 to be installed in the insertion hole 630 is in the lower end side, actually in the front-rear direction. A small locking claw 662 provided on the proximal end side, a neck portion 663 having a smaller diameter than the head portion 661, and a chest portion 664 continuously formed on the neck portion 663 so as to have the same diameter as the head portion 661; A waist portion 665 having a smaller diameter than the chest portion 664 and formed relatively long, a large locking claw 666 extending from the waist portion 665, a small pedestal portion 667 supporting the waist portion 665, and a larger diameter than the small pedestal portion 667 And a large pedestal portion 668.

  The large base portion 668 is provided with a tool insertion groove 669 for inserting a tip of a tool such as a driver. One end of a connection member 670 is provided on the large pedestal portion 668, and adjacent caulking pins 660 are connected to each other via the connection member 670.

  The state shown in FIG. 7 is a state before the caulking pin 660 is fitted into the fixing hole 705 of the case mounting device 700 described later, and the caulking pin 660 is pushed into the insertion hole 630 from the state shown in FIG. Then, the large pedestal portion 668 is fitted into the entrance portion of the insertion hole 630, and the head portion 661 at the tip protrudes from the insertion hole 630 and is fitted into the fixing hole 705 of the case attachment device 700. At this time, since the small locking claw 662 and the large locking claw 666 are respectively locked to the step portion 633 of the insertion hole 630, the caulking pin 660 cannot be removed. In practice, the caulking pin 660 is inserted into the fixing hole 705 of the case attachment device 700 from the front (see, for example, FIG. 5).

  In the present embodiment, four caulking pins 660 as the case fixing means as described above are provided. The case fixing means is used at one place when the substrate storage case 500 is fixed to the cabinet 210. Therefore, the substrate storage case 500 can be fixed to the case attaching device 700 of the slot machine 100 four times. The removal of the substrate storage case 500 is possible only when it is properly permitted. When it is removed, the trace remains, and it is obvious that it has been removed.

<Case mounting device>
The case attaching device 700 is a member that serves as a base for detachably attaching the board storage case 500 combined as described above to the cabinet 210 of the game table, and is integrally formed with a synthetic resin having translucency. is there. The outline of the case attachment device 700 is movable to the case attachment main body 710 having a fixed portion fixed to the inner wall surface of the game table main body and a locking portion having a predetermined shape, and the case attachment main body 710. And a cover part 720 for holding the substrate storage case 500 attached to the case attachment main body part 710 by engaging with the engaging part.

  The case mounting main body 710 shown in FIG. 8 has a bottom surface 711 having a mounting fixing hole 701 through which a fixing tool is inserted as a fixing portion for fixing to the inner wall of the game table main body, and stands substantially vertically from the bottom surface 711. A rising surface 730, an upper edge surface 740 extending substantially parallel to the bottom surface 711 along the upper edge of the rising surface 730, and a falling surface extending downward from the outer edge of the upper edge surface 740 750. The bottom surface 711 and the upright surface 730 form a storage portion 708 that stores the substrate storage case 500 movably inside. The accommodating portion 708 will be described later.

  The bottom surface 711 is a flat portion having an outer shape that substantially matches the outer shape of the substrate storage case 500 and that allows the substrate storage case 500 to slide in a predetermined direction, for example, the left-right direction in FIG. A reinforcing rib 712 is provided at an appropriate position on the rear surface side of the bottom surface 711 (see FIG. 14).

  In addition, as described above, a fixing tool for fixing the case mounting device 700 to the cabinet 210 serving as the inner wall of the game base body, for example, a fixing screw 702 is attached to the bottom surface 711 of the case mounting device 700. Holes 701 are provided at four locations. The mounting fixing hole 701 is formed with a recess 701a so that the head of the fixing screw 702 penetrates, and the head of the fixing screw 702 protrudes from the bottom surface 711 to prevent the substrate storage case 500 from sliding. (See FIG. 9).

  On the other hand, on the back side of the bottom surface 711, there are three positioning bosses 703 (see FIG. 14), and these bosses 703 are fitted into positioning holes (not shown) provided in the back plate 213 of the cabinet 210. By combining, the case mounting device 700 is positioned with respect to the cabinet 210.

  Further, four fixing holes 705 for fitting the caulking pins 660 constituting the case fixing means described above are arranged in the bottom surface 711 of the case attaching device 700 side by side in correspondence with the case fixing means. It is.

  The standing surface 730 that stands up and extends substantially vertically around the bottom surface 711 is the side surface portion 593 of the substrate storage case 500, that is, the periphery of the standing piece 5931 of the front cover member 510 and the rising piece 5932 of the rear cover member 520. Is a surface that faces the rising piece 5931 and the rising piece 5932 at a predetermined interval. For example, a lower standing surface 730 that faces the lower side surface of the substrate storage case 500 stands from the lower edge of the bottom surface 711. Further, a left standing surface 730 stands on the left side surface of the substrate storage case 500, a right standing surface 730 stands on the right side surface, and an upper standing surface 730 stands on the upper side surface from the bottom surface 711. .

  The upper standing surface 730 is formed corresponding to the guide portion 601 of the substrate storage case 500, and the insertion portion standing surface 730 is formed at the center portion corresponding to the insertion portion into which the caulking pin 660 is inserted. In addition, on the left and right sides of the insertion portion standing surface 730, a sealing portion standing surface 730 corresponding to a sealing portion on which the safety lock pin 620 is inserted and sealed is formed. The sealing portion rising surface 730 is formed with a space between the sealing portion and the upper surface of the sealing portion so that the safety lock pin 620 can be inserted even when the substrate storage case 500 is attached. is there. Further, flat portion standing surfaces 730 corresponding to the flat portions formed on the left and right sides of the guide portion of the substrate storage case 500 are formed on the left and right sides of the sealing portion standing surface 730 via stepped portions.

  In addition, the insertion portion standing surface 730 at the center portion is slightly recessed and lower than the sealing portion standing surface 730. For this reason, it is easy to see when the seal seal is affixed, and the substrate storage case 500 is easily taken out.

  And the upper edge surface 740 does not exist in the position corresponding to the guide part which penetrates the safety lock pin 620 and the caulking pin 660. In addition, the upper edge surface 740 extending along the upper edge of each rising surface 730 and the front surface portion 591 of the substrate storage case 500 attached to the bottom surface 711 are formed to be substantially flush with each other. For this reason, it is easy to apply a seal sticker that is hung on the substrate storage case 500 and the case attaching device 700.

  As described above, when the front surface portion 591 of the substrate storage case 500 attached to the case attachment device 700, that is, the second substrate portion 511b, and the upper edge surface 740 extending from the standing surface 730 are substantially flush with each other. In other words, the total height of the rising pieces 5931 and the rising pieces 5932 of the substrate storage case 500 is equal to the height of the rising surface 730 of the case mounting device 700. For this reason, in the side surface portion 593 of the substrate storage case 500, the contact portion between the rising piece 5931 and the rising piece 5932, that is, the connection portion where the front cover member 510 and the rear cover member 520 are in contact is the rising surface 730. Located within the height range. For this reason, since the said connection part is hidden by the said standing surface 730, it becomes impossible to insert an unauthorized member, such as a piano wire, into the said connection part from the side.

  In addition, if the connection part of the front cover member 510 and the rear cover member 520 is formed on the stairs which mutually fit, since the course of the unauthorized member inserted into the connection part bends in the middle, insertion of the unauthorized member is not possible. It becomes more difficult and it becomes harder to play illegal games.

  The connection portion described above is a separation portion that enables the substrate storage case 500 to be separated into the front cover member 510 and the rear cover member 520, and is formed on the side surface portion 593 of the substrate storage case 500.

  A notch is formed at a desired location in the corner of the case mounting main body 710 where the standing surface 730 rises from the bottom surface 711. That is, a notch 751 corresponding to the assembly connecting portion 531 provided on the lower edge of the substrate storage case 500 is opened on the rising surface 730 on the lower side so as to hang from the upper edge surface 740 of the case mounting device 700 to the rising surface 730. (See, for example, FIG. 8). The notch 751 includes an upper edge surface notch through which the assembly connecting portion 531 projecting from the substrate storage case 500 can be inserted and an upright surface notch communicating with the notch at an initial position where the substrate storage case 500 is mounted. Consists of. And this standing surface notch is the width | variety corresponding to the sliding amount of the board | substrate storage case 500, and is extended along the sliding direction. For this reason, even if the substrate storage case 500 is slid, the assembly connecting portion 531 protruding from the substrate storage case 500 is locked to the edge of the notch 751 and the sliding movement is not hindered.

  A case locking portion 760 for locking the substrate storage case 500 is provided at an appropriate position on the rising surface 730 of the case mounting device. The case locking portion 760 includes a first case locking portion and a second case locking portion. The first case locking portion corresponds to the locking protrusion 561 protruding from the right side portion of the guide portion on the upper side surface portion of the substrate storage case 500, for example, and the standing surface 730 on the right side of the upper edge of the case attachment device 700. And a first case locking hole 761 that opens to the upper edge surface 740. Further, the second case locking portion corresponds to, for example, a locking protrusion 562 that protrudes from the left side surface portion of the substrate storage case 500, and the second case engagement portion that opens to the standing surface 730 on the left side of the case mounting device 700. It is a stop hole 762.

  The first case locking hole 761 has a lateral width for receiving the locking protrusion 562 and opens in the upper edge surface 740 located on the right side of the guide portion at an initial position where the substrate storage case 500 is mounted on the case mounting device 700. At the same time, the substrate storage case 500 has a lateral width that allows sliding movement in the left direction and opens to the standing surface 730. Therefore, when the substrate storage case 500 is slid in the left direction, the locking protrusion 562 on the upper side surface is locked to the back surface side of the upper edge surface 740 located on the right side of the guide portion, and the substrate storage is performed. The case 500 is prevented from popping out. In other words, the movement of the substrate storage case 500 from the bottom surface 711 toward the upper edge surface 740 is restricted.

  On the other hand, on the standing surface 730 located on the left side, two locking protrusions 562 protruding from the left side surface of the substrate storage case 500 are engaged as a case locking portion 760 for locking the substrate storage case 500. Two case locking holes 762 are opened at two locations in the upper and lower directions. Therefore, when the substrate storage case 500 is slid in the left direction, the two locking projections 561 are respectively fitted into the upper and lower second locking holes 762 arranged side by side in the vertical direction. Each locking projection 561 is locked to the front edge of the stop hole 762, in other words, the back surface side of the upper edge surface 740. Therefore, the left side surface portion of the substrate storage case 500 is prevented from jumping forward (front side). That is, the movement from the bottom surface 711 toward the upper edge surface 740 is restricted.

  Then, the locking projection 561 of the substrate storage case 500 is inserted into the first case locking hole 761, and the substrate storage case 500 is inserted and moved from the upper edge surface 740 to the bottom surface 711. This state is said that the substrate storage case 500 is in the initial position. On the other hand, when the substrate storage case 500 is slid from the initial position, the locking projection 562 is fitted into the second case locking hole 762. This state is said that the substrate storage case 500 is in a predetermined position.

  Each of the locking projections 561 and 562 provided on the substrate storage case 500 is provided so as to protrude from the standing piece 5931 of the front cover member 510. Each of the locking projections 561 and 562 is provided with a rib on the outer edge so as to have an appropriate thickness, and the apparent thickness is increased.

  On the other hand, in the illustrated embodiment, the falling surface 750 extends from the outer edge of the upper edge surface 740 of the case attaching device 700 toward the bottom surface 711, and the apparent thickness of the rising surface 730 is increased. ing. The distance from the upper edge to the lower edge of the falling surface 750 is longer than the distance from the upper edge to the bottom surface 711 of the rising surface 730. In other words, the lower edge of the falling surface 750 protrudes below the bottom surface 711. Therefore, when the case attachment device 700 is fixed to the cabinet 210, the lower edge of the falling surface 750 contacts the cabinet 210, but the bottom surface 711 does not contact the cabinet 210.

  Further, due to the presence of the falling surface 750, the rising surface 730 and the falling surface 750 are doubly present around the side surface portion 593 of the substrate storage case 500. Therefore, it is impossible to act illegally from the outside of the case mounting device 700 against the side surface portion 593 of the substrate storage case 500 that is double protected. Furthermore, since the bottom surface 711 of the case attachment device 700 exists outside the back surface portion 592 of the substrate storage case 500, it is impossible to act illegally from the bottom surface side.

  As described above, the side surface portion 593 and the back surface portion 592 of the substrate storage case 500 are covered with the case mounting device 700, and only the front surface portion 591 is exposed. For this reason, it is difficult to act illegally from the side surface portion 593 and the back surface portion 592. On the other hand, although the front surface portion 591 is exposed, it is easy to visually recognize because it faces the front. Therefore, if a fraudulent act such as making a hole in the front portion 591 and modifying the circuit board through this hole is easily detected, it is extremely effective in detecting and preventing the fraud.

  The case attaching device 700 is provided with a wiring restraint 770 (hereinafter also referred to as a cable retainer 770) corresponding to each flat cable 900 as a wiring material connected to the connector portion 504 described above. These cable retainers 770 are detachably provided in a recess 741 formed on the upper edge surface 740 of the case attachment device 700.

  The recess 741 is formed corresponding to each flat cable 900. For example, in the illustrated embodiment, the first flat cable 900, that is, the upper edge surface 740 positioned on the right side of the first connector, has a seating surface at a position where the distance from the cabinet 210 is narrow, and the side is open. Thus, a recess 741-1 for the first flat cable 900 is formed.

  In addition, the upper edge surface 740 of the left side of the second connector portion 504 is recessed in correspondence with the second and third flat cables 900 on the left side, so that a recess 741 for the second and third flat cables 900 is obtained. -2 is formed.

  In each recess 741 of the case mounting main body 710 as described above, a pair of wiring restraint mounting holes 742 (hereinafter sometimes simply referred to as mounting holes 742) for mounting the cable retainers 770 are opened, The attachment pieces 771 provided on the cable retainer 770 are locked in these attachment holes 742.

  For example, as shown in FIG. 12, the cable retainer 770, that is, the wiring restraint 770 has a mounting board 772 having a length corresponding to the width of the flat cable 900 applied as a wiring material, one end of the mounting board 772, and a drawing. Then, a gap holding plate 773 that rises from the lower end, a presser plate 774 that pivots upward from the tip of the gap hold plate 773 via a thin portion 773a, and a tip (upper end) of the presser plate 774 are provided. A locking portion 775 having a locking claw 775a, and a locking receiving operation receiving portion 776 for receiving the locking portion 775 and operating the locking claw 775a.

  A pair of attachment pieces 771 corresponding to the attachment holes 742 of the recesses 741 are provided on the back side of the attachment substrate 772. Each attachment piece 771 has its tip directed in the same direction (downward in the drawing), and protrudes from the attachment substrate 772 with a desired interval. Further, each attachment piece 771 is given some elasticity, and each attachment piece 771 is slightly curved so that the attachment piece 771 sandwiches the substrate of the recess 741.

  The upper attachment piece 771 is provided with an attachment / detachment operation piece 777 for attaching / detaching the cable retainer 770 to / from the attachment hole 742 of the recess 741. The attachment / detachment operation piece 777 is provided at the tip of the elastic mounting portion 777a with an elastic attachment portion 777a extending obliquely upward from the root of the upper attachment piece 771, and fitted into the attachment hole 742. A pressure contact portion 777b that is in pressure contact with the upper edge of the attachment hole 742 and an operation portion 777c that is picked when the pressure contact portion 777b is pulled out from the attachment hole 742.

  On the other hand, a holding plate 774 faces the front surface of the mounting substrate 772 with a predetermined interval by a gap holding plate 773, and the holding plate 774 can be turned (opened / closed) with the thin portion 773a as a fulcrum. ing. A locking portion 775 having a locking claw 775 a is provided at the upper end of the presser plate 774 with the same width as that of the interval holding plate 773. Further, the locking claw 775a of the locking portion 775 locks to prevent the presser plate 774 from rotating (opening), and the lock claw 775a is unlocked to release the presser plate 774. A stop receiving operation receiving portion 776 is provided on the upper end side of the mounting substrate 772. The latch receiving operation receiving portion 776 includes a guide piece 778 having substantially the same height as the interval holding plate 773 and an operation piece erected facing the guide piece 778 corresponding to the thickness of the latch portion 775. The operation piece 776a is provided with a claw receiving portion 776b that the locking claw 775a locks, and a pressing portion 776c that is pressed when the locking claw 775a is unlocked.

  Therefore, when the attachment piece 771 of the cable retainer 770 faces the front of the attachment hole 742 of the recess 741 of the case attachment device 700 and the attachment piece 771 is inserted into the attachment hole 742 and moved downward, the attachment piece 771 is While sandwiching the substrate of the recess 741, the impacting portion 777 a is fitted into the mounting piece 771, and the pressure contact portion 777 b is pressed against the upper edge of the mounting hole 742. For this reason, the cable retainer 770 cannot be pulled forward and moved up and down, and is securely attached to the recess 741 of the case attachment device 700.

  On the other hand, when the operation piece 776a is picked to deform the impacting portion 777a to release the pressure contact with the upper edge of the mounting hole 742, the cable presser 770 is moved upward, and further pulled forward, the cable presser 770 is simply Can be removed.

  Further, in order to press the flat cable 900, the pressing portion 776c is pressed to release the locking claw 775a, and the flat cable 900 faces the front surface of the mounting board 772 with the pressing plate 774 free. The presser plate 774 is closed again and the pressing portion 776c is pressed to lock the locking claw 775a. In this way, the flat cable 900 can be neatly collected.

  Furthermore, if the size of the cable retainer 770, that is, the wiring restraint tool is changed according to the flat cable 900 to be applied and attached to the attachment hole 742, the flat cable 900 can be processed without rattling.

  As described above, by providing the cable retainer 770 in the recess 741, each flat cable 900 can be disposed along the board storage case 500. That is, it can be rationally disposed and processed so as not to cause a gap with the substrate storage case 500. If there is no gap between the substrate storage case 500 and the flat cable 900, there is no space for hiding unauthorized modified substrates, which is extremely effective for safety measures. Further, the flat cable 900 that protrudes does not interfere with other devices, and does not obstruct maintenance inspection work or assembly work.

  Further, when a plurality of connector portions 504 are arranged adjacent to each other like the above-described second connector portion 504-2 and third connector portion 504-3, there are a plurality of flat cables 900, 900. Of course, these flat cables 900 are preferably stacked and processed as shown in FIG. That is, the second connector portion 504-2 having a large width is disposed at a position close to the outer edge of the substantially rectangular main control board 503, and the third third portion having a small width is adjacent to the inside of the second connector portion 504-2. The connector part 504-3 is arranged. Then, corresponding flat cables are respectively connected to the second and third connector portions 504-2 and 504-2, and arranged so that each flat cable is pulled out toward the outside of the main control board 503. Then, the wide flat cable 900 is disposed at a position (lower side) close to the substrate storage case (not shown), and the narrow flat cable 900 is disposed on the flat cable 900 in an overlapping manner. Even when there are three or more connector portions 504 and the flat cables 900, the connector portions 504 whose width gradually decreases from the side close to the outer edge of the main control board 503 toward the center are arranged, and the corresponding flat cables In this case, the flat cable 900 whose width is gradually narrowed may be stacked on top of the wide flat cable.

  In this way, when the narrow flat cable 900 is arranged so as to be on the upper side, the narrow flat cable 900 is not hidden by the shadow of the wide flat cable 900. That is, all the flat cables 900 can be visually observed. For this reason, if an unauthorized modification is made to the flat cable 900, it can be immediately recognized, and an illegal act can be detected immediately.

  A cover portion 720 that constitutes the case attachment device 700 together with the case attachment main body portion 710 holds the substrate storage case 500. Further, the cover portion 720 can cover each connector portion 504 and the drawer portion of the flat cable 900, and is detachably attached to the case attachment main body portion 710. Therefore, hereinafter, the cover portion 720 may be referred to as a connector cover 720. In the illustrated embodiment, the first connector cover 720-1 on the first connector side and the second connector cover 720-2 on the second and third connector sides of the bulging portion 512 of the board storage case 500 are provided. It is attached to the left and right (for example, see FIG. 10).

  Therefore, the first connector cover 720-1 located on the right side of the bulging portion 512 covers the first connector portion 504-1 and the end portion of the flat cable 900 connected to the first connector portion 504-1. A bulging portion 721 raised to a predetermined shape so as to cover the upper and lower ends of the bulging portion 721 via a plate-like leg portion 722 for movably attaching to the case mounting main body 710 A rail portion 723 is provided as a loose projection. The raised portion 721 has a space inside, and the flat cable 900 extending from the board storage case 500 is accommodated in the space. The raised portion 721 in the mounted state is configured so as to be almost closed by the side surface of the bulging portion 512 of the substrate storage case 500 and the standing surface 730 of the case mounting device 700, leaving the side portion.

For this reason, the first connector cover 720-1 has a raised portion 721 corresponding to the shape of the connector portion 504-1 and the flat cable 900 and has a stepped cross section, and upper and lower ends of the raised portion 721. Further, a flat leg portion 722 extends from the lower edge of the wall surface so as to be slidable on the upper edge surface 740 of the case mounting main body 710. Further, the leg portion 722 is engaged with a guide groove 790 provided in a case attachment main body 710, which will be described later, so that the connector cover 720 is placed in a predetermined direction, that is, the longitudinal direction of the substrate storage case 500 and the case attachment device 700. A rail portion 723 is provided as a loose projection that guides in the direction. Further, side portions of the ridges 721, with the exception of the flat cable pull outlet 728 as a wiring outlet are closed by the side wall 729 (see FIG. 10-13).

  The leg portion 722 and the rail portion 723 are provided substantially symmetrically above and below the raised portion 721. That is, an upper leg portion 722 is provided on the upper side of the raised portion 721, and a horizontally long tongue-shaped rail portion 723 protrudes at two places on the upper edge portion of the upper leg portion 722. Alternatively, it may be expressed that the middle of the rail portion 723 is interrupted.

  A screw seat portion 724 is provided at one corner of the upper leg portion 722. The screw seat portion 724 is a portion recessed in a circular shape, and has a screw insertion hole 724a at the center. Therefore, if the screw 727 passed through the screw insertion hole 724a is screwed into the screw hole 749 provided in the case attachment device 700, the first connector cover 720-1 can be screwed (see FIG. 10).

  Further, since the screw seat portion 724 is recessed, the head portion of the screw 727 screwed in does not protrude and does not interfere with other members.

  Further, in the illustrated embodiment, a lock hole 725 is formed in the vicinity of the screw seat portion 724, that is, in the right edge portion of the upper leg portion 722 to constitute a lock means described later.

  On the other hand, the lower leg portion 722 is also provided with a rail portion 723 as a loose projection similar to the upper leg portion 722. The rail portion 723 is also divided into two pieces on the way. A locking hole portion 726 is provided in place of the screw seat portion 724 at a position that is substantially symmetrical with the screw seat portion 724. The locking hole portion 726 is faced by a locking tongue piece portion 780 provided as a locking portion of a predetermined shape on a case mounting main body portion 710 of the case mounting device 700 described later. This facing surface is the operation operation surface of the locking tongue piece 780.

  By the way, the connector portion 504 is provided with a pair of lock levers 5040 that can be displaced between an open position where the connection connector 910 can be inserted and removed and a closed position where the connection connector 910 cannot be pulled out. Therefore, as shown in FIG. 26, when the lock lever 5040 is in the open position, the connector cover 720 cannot be attached.

  That is, as shown in FIG. 26B, when the lock lever 5040 is rotated outward and is in the open position, the interval Y ′ between the lock levers 5040 is equal to the lock lever 5040 shown in FIG. It becomes larger than the interval Y in the closed position. On the other hand, the internal spacing X of the legs 722, 722 of the first connector cover 720-1 is determined corresponding to the spacing Y when the lock lever 5040 is in the closed position. Therefore, when the lock lever 5040 is in the open position, even if the first connector cover 720-1 is to be mounted, the lock lever 5040 and the side surface of the leg portion 722 of the first connector cover 720-1 come into contact with each other. The first connector cover 720-1 cannot be mounted at the correct position.

  Therefore, in a state where the flat cable 900 is connected and the lock lever 5040 is not tilted to the closed position, the first connector cover 720-1 cannot be attached, so that forgetting to connect the flat cable 900 does not occur.

  The 2nd connector cover 720-2 which covers the 2nd and 3rd connector parts 504-2 and 3 is also the same composition as the above-mentioned 1st connector cover 720-1. That is, the second flat cable 900 connected to the second and third connector portions located on the left side of the bulging portion 512 and the second connector cover 720-2 covering the connection portion of the third flat cable 900 are The leg portion 722 extending above and below the raised portion 721 and the rail portion 723 provided at the tip of each leg portion 722 are provided. Further, the raised portion 721 is provided with a screw seat portion 724 and a locking hole portion 726. And the cover part 720 of the structure as described above, that is, the connector cover 720 is integrally formed of a synthetic resin having translucency.

  Further, the second connector portion 504-2 and the third connector portion 504-3 also include a lock lever 5040. Therefore, in this case, the second connector cover 720-2 is formed on the basis of the wide second connector portion 504-2 located on the outside. Accordingly, when the lock lever 5040 of the second connector portion 504-2 is in the open position, the second connector cover 720-2 comes into contact with the lock lever 5040, so that the second connector cover 720-2 is correctly attached. I can't.

  Corresponding to the pair of upper and lower rail portions 723 provided on the first connector cover 720-1, the rail portion 723 is fitted into the upper edge surface 740 of the case mounting device 700, and the first connector cover 720-1 is inserted. A pair of upper and lower guide grooves 790 for guiding the right and left are provided. The guide groove 790 is a groove that is open on the front and sides, and is provided with a notch 791 for inserting the rail portion 723 at an appropriate position on the front side, and is latched on the left and right of the notch 791. A piece 792 is provided.

  Therefore, the first connector cover 720-1 is slidably mounted to the left and right by dropping the rail portion 723 of the first connector cover 720-1 together with the notch 791 of the case attachment device 700. At this time, in the illustrated embodiment, all operations can be performed without protruding outside the case mounting main body 710 when viewed from the front. In other words, all the members are arranged so as to be within the projection plane of the case mounting main body 710.

  In the middle of the guide groove 790, as shown in FIG. 27, a wall portion 793 that partitions the guide groove 790 in the sliding direction is provided. Therefore, in the guide groove 790, an inner region 794A in which the connector cover 720 is slidable left and right (the same applies to the drawings below) is formed inside the wall portion 793. Therefore, as shown in FIG. 28A, the connector cover 720 is attached to the case attachment device 700 with the rail portion 723 of the connector cover 720 aligned with the notch 791 of the guide groove 790. Then, when it is slid to the left (inside), the locking tongue piece 780 is fitted and locked in the locking hole 726, and the connector cover 720 is mounted at the correct position (see FIG. 28B). . That is, it becomes the 1st mounting position which covers the fitting part of the connector part 504 and the connection connector 910. FIG. On the other hand, when the connector cover 720 is slid to the right (outside), the rail portion 723 of the connector cover 720 comes into contact with the wall portion 793 to prevent further sliding, and the outer end of the guide groove 790 that opens. Is prevented from falling off (see FIG. 28C).

  On the other hand, in the guide groove 790, an outer region 794B in which the connector cover 720 can be temporarily held is formed on the outer side (right side) of the wall portion 793. Specifically, the rail portion 723 of the connector cover 720 is inserted into the guide groove 790 from the outer end where the guide groove 790 opens. 29, the rail portion 723 is locked from the inside to the inner surface of the locking piece 792 provided in the upper and lower guide grooves 790. As shown in FIG. Therefore, in this state, the connector cover 720 does not fall forward. Further, this state is a state where the connector cover 720 does not cover the connector portion 504 and the connection connector 910. In other words, it can be said that the connector portion 504 is accessible. That is, it is in the vicinity of the fitting portion between the connector portion 504 and the connection connector 910 and becomes the second mounting position that does not hinder the connection connector 910 from being attached or detached.

  Therefore, as described above, the state in which the connector cover 720 is held in the outer region 794B of the guide groove 790 is referred to as the temporary fixing position of the connector cover 720. In this temporary fixing position, the connector portion 504 of the circuit board can be accessed as described above, and therefore, for example, the main control board 503 can be inspected by fitting a cable of an inspection device. Moreover, since the connector cover 720 does not fall, the connector cover 720 is not lost during the inspection.

  In order to attach the connector cover 720 to the board storage case 500, the connector cover 720 is slid inward along the guide groove 790 of the case attachment device 700. At this time, the connector cover 720 may contact the flat cable 900 and further press the flat cable 900. However, in this embodiment, as shown in FIG. 30A, the sliding direction of the connector cover 720 is a direction in which the fitting state between the connector portion 504 and the connection connector 910 is strengthened. That is, the flat cable 900 is slid in the direction of contraction from the extending direction of the flat cable 900. Therefore, when the connector cover 720 is slid, the fitting between the connector portion 504 and the connection connector 910 is not loosened. On the other hand, as shown in FIG. 30B, when the connector cover 720 is slid in the extending direction of the flat cable 900, the flat cable 900 is dragged by the connector cover 720, so that the connector portion 504 and the connection connector 910 are connected. There is a risk of loosening of the fitting.

  The upper edge surface 740 of the case attachment main body 710 is provided with a locking tongue piece 780 that is locked to the locking hole 726 provided in the first connector cover 720-1 as the cover 720 described above. The locking tongue piece 780 is formed as an arm-shaped member having one end as a free end by providing a substantially parallel separating portion connected to one end on the upper edge surface 740 of the case mounting body 710. It is. Therefore, the arm-shaped member has elasticity depending on the material because the base end is connected to the upper edge portion. The locking tongue piece 780 is a locking portion having a predetermined shape provided in the case mounting main body 710.

  Further, on the free end side of the locking tongue piece portion 780, a slope portion 781 that is inclined upward toward the tip end side and a locking surface portion 782 that intersects at an acute angle from the upper end of the slope portion 781 are formed ( (See FIG. 13). Accordingly, the first connector cover 720-1 having the rail portion 723 mounted in the guide groove 790 is moved in the inner direction (the left side in the drawing) which is the direction in which the locking tongue piece 780 is locked in the locking hole 726. When the inclined surface portion 781 is pressed downward by the lower surface of the first connector cover 720-1 and the locking tongue piece portion 780 is elastically deformed downward, the inclined surface portion 781 reaches the locking hole portion 726. Then, the inclined surface portion 781 is fitted into the locking hole portion 726.

  On the other hand, in this locked state, even if the first connector cover 720-1 is moved in the direction opposite to the above, that is, in the outer direction, which is the direction in which the first connector cover 720-1 is removed, Since the locking surface 782 of the locking tongue piece 780 is locked to the inner wall of the portion 726, it cannot be moved.

  However, if the locking tongue piece 780 is deformed to release the locking between the locking surface portion 782 and the locking hole portion 726, the first connector cover 720-1 can be moved in the removing direction. For this purpose, the inclined portion 781 of the locking tongue piece 780 may be pressed with a release operation article. For example, the locking tongue piece portion 780 is deformed by pressing the inclined surface portion 781 with a fingertip passing through the locking hole portion 726 or with an instrument such as a screwdriver inserted through the locking hole portion 726. In this case, the direction of the release operation for releasing the locking between the locking tongue piece 780 and the locking hole 726 is the direction facing the locking tongue piece 780 from the locking hole 726.

  On the other hand, the direction of the releasing operation is not limited to the direction facing the locking tongue piece 780 from the locking hole 726. In other words, the release operation for removing the connector cover 720, which is the cover part 720 for holding the substrate storage case 500, only needs to be able to deform the locking tongue piece part 780. Therefore, for example, a hook whose tip is bent into a hook shape is made to enter from the side of the locking tongue piece 780 as a release operation object, and the hook tongue is rotated at the tip of the hook tongue portion by rotating the hook. The part 780 can be pressed.

  Therefore, in order to prevent the release operation, that is, to prevent the release operation article from entering, the arrangement is made so that a space or a margin is not formed on the front surface side of the locking tongue piece 780. For example, the reel substrate cover 223 provided on the reel unit 220 disposed adjacent to the predetermined device as described below faces the front surface of the locking tongue piece 780. Further, in order to prevent the insertion from the side, the obstacle member 789 is arranged on the side of the locking tongue piece 780.

  First, for example, in the embodiment shown in FIG. 20, the obstruction member that prevents the release operation article from being inserted is provided with rib-like obstruction members 788 around the locking hole portion 726, specifically on the upper edge and the right edge. , And projecting from the leg portion 722 of the connector cover 720. Therefore, it is possible to reliably prevent an intrusion of an unauthorized game member (release operation article) such as a piano wire from the outside.

  Although the obstacle members 788 and 789 are not shown, they can be provided on the reel board cover 223 side, for example, or can be provided on the case attachment main body 710, and may be provided on both sides. .

  On the other hand, as shown in FIG. 31, a rib 7221 may be provided on the back side of the connector cover 720 for reinforcement. That is, in order to increase the strength of the connector cover 720, the reinforcing rib 7221 is provided at an appropriate position, and the rib 7261 is provided around the locking hole 726 described above.

  When the rib 7261 is provided around the locking hole 726, the operation when the locking tongue piece 780 is fitted increases. For this reason, when the engaging tongue piece 780 is fitted and engaged with the engaging hole portion 726, an operation sound such as “click” is generated, and the engaging tongue piece portion 780 is surely engaged with the engaging hole. It is possible to notify the operator that the portion 726 has been fitted and locked. Further, when the rib 7261 is provided around the locking hole portion 726, the locking hole portion 726 becomes deep, and there is an effect that the locking with the locking tongue piece portion 780 is ensured.

  Next, in order to structurally prevent the release operation article from being inserted, for example, a locking tongue piece portion 780 as a locking portion or a required portion of a predetermined device arranged adjacently so as to hinder the release operation If either one of these is a convex portion and the other is a concave portion, the release operation article cannot be inserted. In addition, since a reel unit 220, which will be described later, exists as a predetermined device on the front side, it is extremely difficult to insert a release operation article from the front side.

  Accordingly, it is impossible to release the cover portion 720 by inserting the release operation article, and it is impossible to remove the connector cover 720 illegally. If the connector cover 720 cannot be removed, it is impossible to access the board storage case 500, and the main control board 503 stored in the board storage case 500 cannot be tampered with. It can be prevented in advance.

  Further, the connector cover 720 that is the cover portion 720 can be securely fixed. That is, in a state where the locking surface portion 782 of the locking tongue piece portion 780 is locked to the locking hole portion 726, the screw seat portion 724 provided on the upper side and the upper edge surface 740 of the case attachment main body portion 710 are provided. Since the screw hole 749 coincides with the screw hole 749, it is screwed with a screw 727. Similarly, the lock hole 725 provided in the vicinity of the screw seat portion 724 and the lock hole 748 provided in the vicinity of the screw hole 749 coincide with each other. Therefore, the lock holes 725 and 748 may be sealed with a lock material such as a padlock 747a or a one-way binding band 747b (see FIG. 11).

  The second connector cover 720-2 located on the left side of the substrate storage case 500, that is, the second connector cover 720-2 covering each flat cable 900 connected to the second and third connector portions is also the first connector cover 720 described above. Since it is the same as the configuration of −1, parts having the same function are denoted by the same reference numerals and description thereof is omitted. The second connector cover 720-2 on this side also completes all necessary operations and operations within the projection surface of the case mounting main body 710.

  And what makes the insertion of the release operation article difficult is not limited to the above-described structure. That is, even with the arrangement configuration of the reel unit 220 and the cover portion 720, it becomes difficult to insert the release operation article as described above.

  For example, a required portion provided on the reel unit 220 as a predetermined device so as to hinder the release operation is formed larger than the locking tongue piece 780, and the arrangement is made so that the gap between the two is as small as possible. It is. That is, the required portion of the reel unit 220 is formed larger than the inclined surface portion 781 of the locking tongue piece portion 780 that faces the locking hole portion 726 as the operation operation surface. If it does in this way, it will be difficult to insert the release operation thing toward the latching tongue piece part 780 which is a latching part, and it can cope with the penetration | invasion not only from the front but from the side.

  On the other hand, as described above, the connector cover 720 cannot be moved when the locking surface 782 of the locking tongue piece 780 is locked to the locking hole 726. Therefore, if the locking tongue piece 780 facing the locking hole 726 cannot be pressed, the substrate storage case 500 cannot be removed, and unauthorized modification to the main control board 503 can be prevented.

  Therefore, in the illustrated embodiment, the reel serving as the predetermined device is attached to the front surface side of the locking hole portion 726 before the substrate storage case 500 so that the release operation with respect to the locking tongue piece portion 780 cannot be performed. A unit 220 is provided, and a reel board cover 223 that is a required part of the reel unit 220 faces the front surface of the slope portion 781 of the locking tongue piece 780.

  As described above, the reel unit 220 for displaying a pattern is provided with three rows of reels on the reel frame 221, and is detachably attached to the reel unit mounting table 218 provided in the cabinet 210 of the game table. It is. A reel substrate 222 as a relay substrate is mounted on the rear side of the reel unit 220, and this reel substrate 222 is covered with a reel substrate cover 223 (see FIG. 16). The reel unit 220 is installed in the cabinet 210 of the game table prior to the substrate storage case 500 as described above.

  As shown in FIG. 17, for example, the reel substrate cover 223 has a space inside and is almost closed except for the wiring lead-out portion. That is, in the illustrated embodiment, a back plate portion 2231 that forms a substrate housing portion where the reel substrate 222 is located, a swash plate portion 2232 that extends obliquely from the upper edge of the back plate portion 2231, and a back plate portion 2231. A concave plate portion 2233 that is recessed leaving a part of the lower edge, a side concave plate portion 2234 that protrudes to the side of the back plate portion 2231 at the same height as the concave plate portion 2233, the back plate portion 2231, and the swash plate Part 2232, concave plate part 2233, and body plate part 2235 extending from each side edge portion of side concave plate part 2234, and has the same translucency as reel frame 221 or resin case 221. It is integrally formed of a synthetic resin having

  A screw receiving seat 2236 for attaching the reel substrate cover 223 to the reel frame 221 is provided in the concave plate portion 2233 and the side concave plate portion 2234 so as to be recessed in a circular shape. The upper body plate 2237 extending from the upper edge of the swash plate portion 2232 has a semicircular wiring hole 2238 through which a wiring cord connected corresponding to each reel is passed. Since the wiring hole 2238 has a smaller diameter than the connector connected to the wiring cord, the wiring hole 2238 functions to prevent the wiring cord from coming off.

  In addition, a terminal hole 2239 through which a connector terminal provided on the reel substrate 222 faces is opened below the side concave plate portion 2234. Although not shown in FIG. 17, an opening is also formed in the left body plate.

  Then, on the left and right sides of the back plate portion 2231 of the reel board cover 223, a convex portion 820 having a predetermined shape is formed corresponding to the locking hole portion 726 of the connector cover 720 fixed to the case mounting device 700. The inclined surface 821 of the portion 820 faces the locking hole portion 726 at a predetermined interval. That is, the convex portion 820 is a required portion that hinders the release operation. The predetermined interval is a state in which an operation for releasing the locking between the locking hole portion 726 and the locking tongue piece portion 780 cannot be performed. This is an interval at which a finger or a tool cannot be inserted in order to press the piece 780, and is an interval that does not hinder the mounting operation of the substrate storage case 500. Further, the inclined surface 821 of the convex portion 820 is formed so as to include a larger surface than the inclined surface portion 781 facing the locking hole portion 726 serving as an operation operation surface for pressing the locking tongue piece portion 780. The locking hole 726 is covered (see, for example, FIG. 19).

  Next, a procedure for attaching the board storage case 500 containing the main control board 503 as described above to the cabinet 210 of the game table will be briefly described. In general, the substrate storage case 500 is attached at the end of the assembly process. That is, first, the case attachment device 700 is screwed to the predetermined position of the cabinet 210 with the fixing screw 702 (see FIG. 18A). Further, the reel unit 220 is detachably attached to the reel unit mounting table 218 provided in the cabinet 210. At this time, the convex portion 820 of the reel substrate cover 223 provided on the reel unit 220 is relative to the tip end portion of the locking tongue piece portion 780 of the case mounting device 700 (the locking hole portion 726 when the connector cover 720 is attached). It is in the position to do. That is, the reel board cover 223 of the reel unit 220 covers the lower edge portion of the case attachment device 700 and the lower edge portion of the case attachment device 700 is hidden behind the reel unit 220 when viewed from the front.

  In the state as described above, the main control board 503 is stored in the board storage case 500, and the safety lock pin 620 is attached and sealed so that it cannot be opened (hereinafter simply referred to as a regular board). ) In front of the case mounting device 700.

  At this time, the upper edge side of the regular substrate is set to the front, and the lower edge side is set to the back so as to be inclined. That is, the lower edge side of the regular substrate is inserted into the accommodating portion 708 formed in the case mounting device 700 first. The accommodating portion 708 is a space portion that is surrounded by the bottom surface 711 of the case attachment device 700 and the surrounding standing surface 730 and that is open on the front surface side. And this accommodating part 708 is comprised so that the board | substrate storage case 500 can move to a predetermined direction.

  Therefore, the assembly connecting portion 531 provided on the lower edge side of the substrate storage case 500 is fitted into the notch 751 provided on the upper edge surface 740 of the case attachment main body portion 710 of the case attachment device 700. At this position, the two locking projections 562 provided on the left edge portion of the substrate storage case 500 are positioned inside the case mounting main body 710. Further, the locking projection 561 protruding from the right side of the guide portion 601 at the upper edge of the substrate storage case 500 coincides with the position of the case locking hole 761 provided at the upper edge of the case mounting main body 710. .

  Therefore, in this state, the regular board is dropped into the case attachment main body 710 so as to be rotated backward with the lower edge side of the regular board as a fulcrum (see FIG. 18B). In this state, the three locking projections 561 and 562 are still located in the case attachment main body 710, and the substrate storage case 500 is in the initial position.

  Therefore, the regular substrate is slightly slid to the left. At this time, since the substrate portion 511 is formed flat, there is no hindrance to the slide movement. When the substrate storage case 500 slides to the left, the second engagement protrusions 562 projecting from the left side edge portion of the substrate storage case 500 are opened on the left standing surface 730 of the case mounting main body 710. The stopper 762 is fitted and locked. In addition, a locking projection 561 protruding from the right upper edge of the substrate storage case 500 is locked to the left end portion of the first locking hole 761 provided in the upper edge surface 740. That is, the substrate storage case 500 moves to a predetermined position.

  In this state, that is, when the substrate storage case 500 is located at a predetermined position, the insertion hole 630 opened in the guide portion of the substrate storage case 500 and the fixing hole 705 provided in the case attachment device 700 coincide. Therefore, the caulking pin 660 is driven from the insertion hole 630 toward the fixing hole 705. Once the caulking pin 660 is driven, the caulking pin 660 cannot be removed. In other words, the substrate storage case 500 can be fixed at a predetermined position of the storage portion 708.

  On the other hand, a flat cable 900 is connected to each connector portion 504. Further, the flat cable 900 is compactly fixed and fixed along the outer shapes of the substrate storage case 500 and the case mounting device 700 by the cable holder 770. Specifically, as shown in FIG. 12, the flat cable 900 connected to the first connector portion 504-1 on the right side is folded rightward and bent downward along the recess 741 of the case mounting device 700. Then, the cable holder 770 is placed on the mounting board 772 of the cable presser 770, pressed down by the presser board 774, and the presser claw 775a is locked to fix the presser board 774, and the flat cable 900 is placed in the lateral direction of the case mounting device 700. Pull out. At this time, as described above, the flat cable 900 can be processed so as not to float along the outer surfaces of the substrate storage case 500 and the case attachment device 700.

  The second and third flat cables 900 connected to the second and third connector portions 504-2 located on the left side of the board storage case 500 are connected together in the same manner as the first flat cable 900. They are gathered together by the presser 770 and pulled out to the left side of the case mounting device 700. Of course, before the board storage case 500 is dropped into the case mounting main body 710, each flat cable 900 may be connected to each corresponding connector.

  Next, the connector cover 720 as the cover portion 720 is attached. As described above, the connector cover 720 is configured to be operable on the projection plane of the case attachment device 700. Even so, the work can be performed without any trouble (see FIG. 18C).

  That is, the connector cover 720 faces the front of the flat cable 900 collected as described above, and the rail portions 723 provided on the upper and lower sides are dropped into the guide groove 790 in alignment with the notches of the upper edge surface 740. Then, when the connector cover 720 is moved inward, the locking tongue piece 780 is pressed, so that the locking tongue piece 780 is deformed downward to escape the inclined surface portion 781, and when the engaging hole portion 726 reaches the inclined surface portion 781, The slanted surface portion 781 is fitted into the locking hole portion 726 due to the return deformation, and the locking surface portion 782 is locked to the inner surface of the locking hole portion 726. In addition, a part of the connector cover 720 that is a cover portion, for example, the left end surface is in contact with the right side surface of the substrate storage case 500. Therefore, in this state, the connector cover 720 is prevented from moving outward. Then, the connector cover 720 holds the substrate storage case 500.

  In addition, the locking hole 726 is hidden behind the reel unit 220, and the protrusion 820 provided on the reel substrate cover 223 provided on the reel unit 220 faces the front of the locking hole 726. The locking tongue piece 780 cannot be operated through the hole 726 to release the locking. In order to release these locks, it is necessary to remove the reel unit 220, which is very burdensome for those who play illegal games.

  In a state in which the locking tongue piece 780 of the board storage case 500 is locked in the locking hole 726 of the connector cover 720 as the cover, the screw seat 724 and the screw hole 749 coincide with each other, and the lock hole 725 The lock hole 748 matches. Therefore, if the screw 727 is screwed into the screw hole 749 from the screw seat portion 724, the connector cover 720 is fixed at the two locations of the screw 727 and the locking tongue piece portion 780, so that secure fixing is possible. is there.

  Further, when the lock hole 725 and the lock hole 748 are sealed through a padlock 747a, a binding band 747b or the like as a lock means, safety can be further improved (see FIG. 11).

  Further, as shown in FIG. 15, if the seal seal S is pasted on the front surface of the substrate storage case 500 and the first connector cover 720-1, the first connector cover 720-1 is moved. Then, since the seal seal S is broken, an illegal act can be easily found.

  As described above, it is necessary to remove the reel unit 220 in order to move the connector cover 720 that is a cover portion for holding the substrate storage case 500. Therefore, the reel unit 220 itself can be configured not to be removed. That is, in the embodiment shown in FIG. 21, the reel unit mounting table 218 on which the reel unit 220 is arranged and the reel unit 220 can be locked by providing a locking means such as a padlock 850, for example. If comprised in this way, since the person who does not have an unlocking means cannot remove the reel unit 220, the safety | security with respect to an unauthorized modification improves more.

  Even if the connector cover 720 can be removed, the board storage case 500 is locked in the case mounting main body 710 with the locking projections 561 inserted into the first case locking holes 761. A locking pin 660 is located at a predetermined position where the locking protrusion 562 is fitted and locked in the case locking hole 762, and the caulking pin 660 is directed from the insertion hole 630 of the substrate storage case 500 toward the fixing hole 705 of the case mounting device 700. It is driven in. For this reason, this caulking pin 660 cannot be pulled out without cutting. In addition, even if the caulking pin 660 is pulled out, in order to remove the board storage case 500, it is further moved to an initial position where the locking projections 561 and 562 and the case locking holes 761 and 762 can be unlocked. There must be. Accordingly, the removal of the substrate storage case 500 is very time-consuming and leaves a lot of traces. For this reason, the security against fraud is extremely high.

  As described above, when the substrate storage case 500 is attached to the case attachment device 700, a predetermined procedure is followed. That is, in the above-described embodiment, first, the substrate storage case 500 is brought to a position where it can be inserted into the storage portion 708 of the case mounting apparatus 700, and then the storage portion 708 is inserted from the position where the substrate storage case 500 can be inserted. The substrate storage case 500 is prevented from falling off the case mounting device 700 by being positioned inside and sliding the substrate storage case 500 to the left.

  Specifically, the assembly connecting portion 531 protruding from the substrate storage case 500 is replaced by the notch 751 of the upper edge surface 740, and the locking projection 561 provided on the upper edge portion is replaced by the case locking hole 761. Then, the substrate storage case 500 is inserted into the storage portion 708. Next, the substrate storage case 500 is slid to the left to lock the assembly connecting portion 531 to the back side of the upper edge surface 740 and the locking protrusion 561 is moved from the case locking hole 761 to the upper edge surface 740. The locking projection 562 provided on the left edge portion of the substrate storage case 500 is locked to the back side of the upper edge surface 740 from the case locking hole 762.

  Therefore, when removing the substrate storage case 500, a procedure reverse to the above must be performed. For this reason, it is a very heavy burden for those who perform fraud. In other words, it can be said that safety against fraud is high.

  Further, as described above, the slidable connector cover 720 is provided, and in order to fix the board storage case 500, the connector cover 720 is placed in the guide groove 790 provided in the case mounting device 700 in the board storage case 500. It must be slid in the direction of. On the other hand, when removing the substrate storage case 500, the connector cover 720 must first be removed by sliding the connector cover 720 in the reverse direction, that is, outward. Moreover, in order to remove the connector cover 720, as described above, a troublesome procedure must be taken. Therefore, this connector cover 720 also increases safety against fraud.

  By the way, the case attachment device 700 attached in the cabinet 210 as described above, the substrate storage case 500 inserted in the case attachment device 700, the cover portion 720 for holding the substrate storage case 500, and the reel The frame 221 and the reel substrate cover 223 are all molded from a synthetic resin having the same translucency. Therefore, in the state where they are assembled together, the separation of each member becomes unclear. For this reason, a person who intends to commit fraud does not know where the fraudulent act may be performed, and the safety against the fraud also increases from this point.

  In the above-described embodiment, the case where the reel unit 220 is used as the predetermined device disposed adjacent to the substrate storage case 500 has been described. However, the predetermined device is not limited to the reel unit 220. For example, in the embodiment shown in FIG. 22, as a predetermined device, a sub board storage case 570 storing a sub control board is attached to the side plate 214 of the cabinet 210. In the illustrated embodiment, the sub-board storage case 570 is mounted in the cabinet 210 via a case mounting device 709 provided on the side plate 214.

  The sub-board storage case 570 is unlocked by the cover portion 720 of the case mounting device 700 to which the substrate storage case 500 is mounted and the locking portion provided in the case mounting main body portion 710, for example, the locking tongue piece portion 780. The required part which prevents the releasing operation to be performed, for example, the protrusion part 571 is provided.

  Therefore, also in this embodiment, when removing the board storage case 500 containing the main control board 503, the sub board storage case 570 must be removed, and unauthorized modification to the main control board 503 is prevented beforehand. be able to.

  A metal plate 831 can also be applied as the case attachment device. That is, for example, as shown in FIG. 23, a board storage case 500 in which the main control board 503 is stored in a metal plate 831 fixed to the back plate 213 of the cabinet 210 is screwed to the metal plate 831 with a male screw 832. For this reason, the metal plate 831 has a female screw portion (not shown), and a male screw 832 passed through the substrate storage case 500 is screwed into the female screw portion so that the substrate storage case 500 is attached to the metal plate. It is attached to 831.

  A locking projection 813 is provided as a required portion at a predetermined position of the reel frame 221 so as to prevent the substrate storage case 500 from being removed. On the other hand, at the lower corner of the substrate storage case 500, a receiving portion 811 that receives the locking projection 813 corresponding to the locking projection 813, and a locking jaw portion 812 that the locking projection 813 locks. And are provided.

  Therefore, in a state where the reel unit 220 is mounted on the reel unit mounting table 218 and attached at a predetermined position, the substrate storage case 500 is pushed between the reel unit 220 and the metal plate 831, and the engaging projection 813 is engaged. The stop jaw portion 812 is locked.

  Therefore, even if the male screw 832 is removed, the substrate storage case 500 cannot be pulled up, and therefore the substrate storage case 500 cannot be removed. In order to remove the substrate storage case 500, the reel unit 220 must be moved to unlock the locking projection 813 and the locking jaw 812.

  According to this embodiment, in order to remove the substrate storage case 500, the reel unit 220 must be moved to release the engagement between the engagement protrusion 813 and the engagement jaw portion 812. When attaching the reel unit 220, the reel unit 220 does not interfere with the attachment. Therefore, although illegal games can be prevented, workability is not impaired.

  FIG. 24 shows still another embodiment. In this embodiment, an engaging protrusion 841 is provided at a predetermined position of the substrate storage case 500, and in the illustrated embodiment, at the lower corner. On the other hand, the shape of the reel frame 221 of the reel unit 220 is made to be a shape that can be engaged with the engagement protrusion 841. Then, the substrate storage case 500 is faced above the reel unit 220, and then the substrate storage case 500 is lowered along the metal plate 831 as a fixing portion of the case mounting device, and the reel frame 221 and the metal plate 831 The substrate storage case 500 is fixed to the metal plate 831 with the male screw 832.

  At this time, the engagement projection 841 is guided by the shape of the reel frame 221, for example, the inclined surface 221 a of the upper half of the back surface, so that the substrate storage case 500 can be inserted. The engaging protrusion 841 engages with the inclined surface 221b in the lower half portion of the back surface, so that it cannot be pulled out. Therefore, in this embodiment, the inclined surface 221a and the inclined surface 221b correspond to required portions that do not hinder the mounting operation of the substrate storage case 500 but hinder the removal operation.

  If comprised in this way, the board | substrate storage case 500 once attached to the metal plate 831 cannot be taken out unless the engagement with the engaging projection part 841 and the reel unit 220 is cancelled | released. That is, at least the reel unit 220 must be moved until the engagement between the engagement protrusion 841 and the reel unit 220 is released.

  Therefore, it is impossible to illegally modify the substrate storage case 500, and illegal games can be prevented. On the other hand, when the substrate storage case 500 is attached, the presence of the reel unit 220 arranged in advance in the cabinet 210 does not deteriorate workability.

  By the way, in any of the above-described embodiments, the case attachment device 700 as the attachment means for attaching the substrate storage case 500 to the inside of the main body 201 is difficult to perform an illegal act behind the shadows of various devices such as a reel unit. Although described as a thing, from a different point of view, it may be said that the case attachment device 700 for attaching the substrate storage case 500 is arranged at a position where the removal operation is hindered by any of the various devices. It can also be configured.

  The present invention has been described with reference to the illustrated embodiments. However, the present invention is not limited to the above-described embodiments, and can be appropriately implemented without changing the configuration described in the claims. For example, in the above-described embodiment, the case where a flat cable is applied as the wiring material is shown, but other things such as a harness can also be applied.
