  Next, the structure of the main control board assembly 200 that houses the main control board 100 in the board case and the mounting structure thereof will be described. Here, FIG. 3 is an exploded perspective view of the main control board assembly 200, and FIG. 4 is a perspective view showing a state where the main control board assembly 200 is attached to the mounting bracket 300. The main control board assembly 200 mainly includes a board case including a case main body 210 and a case lid 260 and a main control board 100 accommodated in the board case.

  First, the case body 210 constituting one of the substrate cases is integrally formed of a transparent plastic as a substantially rectangular box that opens on the side that holds and accommodates the main control board 100. The main control board 100 has electronic components such as a CPU and a ROM mounted on one mounting surface, and the opposite surface serves as a reflow surface for soldering these electronic components, and the reflow surface is on the bottom surface of the case body 210. Oppositely, it is attached via a small screw or the like (not shown).

  On the upper end portion of the case body 210, hinge shaft portions 211 for hinge coupling with the case lid 260 are formed at predetermined three locations. Further, locking arms 212 each having a locking hole 212a and extending forward are formed at two locations on the lower end portion of the case body 210. In addition, a cylindrical container-shaped caulking opening 213 that engages the case lid 260 so as not to be detached again is formed at four predetermined positions at the lower end.

  Next, the case lid 260 is integrally formed of a transparent plastic as a substantially rectangular box that opens on the side facing the case main body 210. A hinge bearing portion 261 is formed at the upper end portion of the case lid 260 so as to be aligned with the hinge shaft portion 211 of the case main body 210 described above, and a locking arm 212 of the case main body 210 is formed at the lower end portion thereof. A locking projection 262 is formed for alignment.

  Further, at the lower end portion of the case lid 260, a caulking opening portion 263 having the same shape facing the caulking opening portion 213 of the case main body 210 is formed at a position where it is aligned. In addition, caulking openings 264 having the same shape as that described above are formed at four locations on one side of the case lid 260.

  Each of the caulking openings 263 and 264 is connected to the main body portion 265 of the case lid body 260 (the portion facing the case main body 210 and accommodating the main control board 100) via a cantilever connecting portion having a relatively small cross-sectional area. It is integrally formed with a little separation. Further, a projecting frame portion 266 that is substantially rectangular in a front view and projects from the main body portion 265 of the case lid 260 so as to surround the entire caulking opening 264 is integrally formed.

  The case main body 210 and the case lid body 260 are coupled to each other so that the hinge shaft portion 211 and the hinge bearing portion 261 are fitted to each other so as to be able to swing open and close. When the main control board 100 is accommodated and the case lid 260 is closed to the case main body 210 side, the locking hole 212a of the locking arm 212 is locked to the locking protrusion 262 of the case lid 260 and temporarily closed.

  In this state, the case main body 210 and the case lid 260 can be easily opened. Therefore, when mounted on an actual machine, the pair of caulking openings 213 and 263 at least at one location facing each other is shown in FIG. 3 is inserted and engaged inside. In this way, these case members are “crimped” together so that they cannot be re-detached, the cantilever opening 263 is cut off and the caulking opening 263 is separated from the main body portion 265 so that the substrate case cannot be opened. Yes. This makes it difficult to open the substrate case, and even if it is illegally opened, the trace remains.

  The main control board assembly 200 accommodated and assembled with the main control board 100 is attached to the back plate 2 a of the housing 2 via the mounting bracket 300. As shown in FIG. 3, the mounting bracket 300 includes a substrate portion 301 having a flat front surface on which a substrate case is placed, a rib 302 that is partially erected from the left edge or the lower edge of the substrate portion 301, and a substrate A support base 303 standing on the right edge of the part 301 and a sealing part 304 projecting further forward from the front surface of the support base 303 are mainly formed integrally.

  Note that the upper end side of the substrate portion 301 is greatly opened and is formed in a substantially U shape when viewed from the front. This ensures a required rigidity (mechanical strength) as the mounting bracket 300 and reduces the weight. Because.

  Screw holes 305 for fixing to the back plate 2 a of the housing 2 are formed in the substrate portion 301 at a plurality of predetermined locations. In addition, on the inner wall of the rib 302 on the left edge, two engaging recesses 306 are formed at the top and bottom, and a pair of locking arms 307 extending forward are formed on the upper and lower ends on the right side of the base plate 301. ing. Further, a caulking opening 310 having a cylindrical container shape is formed on the right side of the base plate 301 so as to face the caulking opening 264 of the case lid 260 and engage with the caulking opening 264 in a non-removable manner.

  The main control board assembly 200 engages the engaging arm 307 at the corner of the protruding frame portion 266 while engaging the engaging convex portion 267 formed on the left end portion of the case lid 260 with the engaging concave portion 306 of the mounting bracket 300. The locking protrusion 307a at the tip of the is locked. As a result, the main control board assembly 200 is stably held by the mounting bracket 300.

  At this time, the engagement medium 700 described above is inserted into and internally engaged with any pair of the caulking opening 310 of the mounting bracket 300 and the caulking opening 264 of the case lid 260. As a result, the main control board assembly (board case) 200 cannot be removed from the mounting bracket 300 unless the connecting portion of the caulking opening 264 is cut and separated from the main body portion 265, and it is difficult to execute illegal takeoff or the like. I have to. Further, even if the main control board assembly 200 is replaced with a modified product or the like, the fact can be quickly found by the destruction trace of the connecting portion of the caulking opening 264.

  As shown in FIG. 5, when the main control board assembly 200 is attached to the mounting bracket 300, the protruding frame portion 266 of the case lid 260 is placed on the support base portion 303 and the front surface of the protruding frame portion 266. And the sealing surface 304a of the sealing portion 304 are located on and substantially adjacent to each other. The main control board assembly 200 attached in a regular procedure spans between the protruding frame portion 266 and the sealing portion 304 (sealing surface 304a), and is a sealing seal 320 made of a paper sheet or a resin film sheet. Is attached and sealed by this.

  The seal seal 320 is made of a material that is easy to tear compared to the adhesive force in order to leave a desorption trace of the main control board assembly 200, but uses an adhesive (adhesive) that cannot be reattached once it is peeled off. It may be a thing.

  In order to effectively prevent unauthorized access to the seal seal 320, the seal cover member 400 is attached to the seal portion according to the present invention so as not to be detached. Hereinafter, the sealing structure using the sealing cover member 400 will be further described. FIG. 6 is a cross-sectional view of a sealed portion (sealed portion 304) to which the sealing cover member 400 is attached.

  As shown in FIGS. 3, 5, and 6, for example, four cylindrical container-shaped caulking openings 330 are integrally formed in the sealing portion 304 of the mounting bracket 300.

  On the other hand, the sealing cover member 400 is provided on one side of a rectangular plate-shaped cover main body 401 that covers the sealing seal 320, and a cylindrical container-shaped caulking opening 410 via two cantilevered connecting portions 420. However, four integrally formed corresponding to the caulking opening 330 of the mounting bracket 300 described above.

  The seal cover member 400 is mounted as follows after the seal seal 320 is properly attached to the protruding frame portion 266 of the case lid 260 and the sealing portion 304 of the mounting bracket 300. That is, at the position where the cover part main body 401 of the seal cover member 400 covers the seal seal 320, the caulking opening 410 of the seal cover member 400 is opposed to each caulking opening 330 of the mounting bracket 300, respectively. Are engaged with each other with an engagement medium 450 interposed therebetween.

  For example, as shown in FIG. 7, the engagement medium 450 has a hollow and cylindrical main body 451 and is integrally formed of plastic or the like. The engagement medium 450 includes a pair of engagement members each having an outer surface that gradually protrudes and inclines in the radial direction toward the axial center of the main body 451, and locking surfaces 452a and 453a that face each other in the central direction of the main body 451. Stop projections 452 and 453 are formed at two locations on the opposite sides of the main body 451.

  The locking projections 452 and 453 are separated from the main body 451 by the grooves 452b and 453b, leaving only the outer sides in the axial direction, and are elastically deformed inward from the normal position where they protrude slightly outward from the outer circumference of the cylinder of the main body 451. It is made possible.

  As shown enlarged in the circle of FIG. 6, stepped portions 411 and 331 are formed on the inner walls of the caulking openings 410 and 330, respectively, which expand in diameter at predetermined positions from the openings. When the end portions of the engagement medium 450 are inserted into the pair of caulking openings 410 and 330 facing each other, the locking projections 452 and 453 are elastically deformed inward, and the positions of the step portions 411 and 331 To return to the normal position and engage. That is, the engaging medium 450 inserted into the caulking openings 410 and 330 is prevented from coming off by the engaging surfaces 452a and 243a of the engaging protrusions 452 and 453 being engaged with the respective step portions 411 and 331. Internally engaged in the state.

  In this way, the sealing cover member 400 is detachably attached to the support base portion 303 of the mounting bracket 300 while covering and protecting the sealing seal 320. Accordingly, unauthorized access to the seal seal 320 can be effectively prevented, and it is extremely difficult to execute unauthorized actions such as taking the main control board assembly (board case) 200 from the mounting bracket 300.

  Further, since the sealing cover member 400 cannot be removed unless the connecting portion 420 of the caulking opening 410 to the cover body 401 is broken or cut, unauthorized access to the sealing seal 320 or replacement of the main control board assembly 200 is performed. And the like can be quickly and easily found by the destruction (cutting) trace.

  Further, the sealing cover member 400 can be reused a plurality of times, and the opening history of the sealing cover member 400 can be managed based on the destruction trace of the connecting portion 420. For example, when the slot machine 1 is shipped from the factory, the engagement medium 450 is interposed and sealed in the pair of the lower caulking openings 410 and 330. For example, as shown in FIG. 8, when the main control board assembly 200 is normally removed from the mounting bracket 300 for periodic inspection of the main control board 100, the connecting portion 420 of the sealing cover member 400 is cut, After the engagement state of the caulking openings 410 and 330 is released, the sealing cover member 400 is detached and the sealing seal 320 is opened.

  Then, when sealing again, the sealing cover member 400 is attached to the pair of caulking openings 410 and 330 one by one with the engaging medium 450 interposed therebetween. In this way, the history that the main control board assembly 200 is properly opened can be managed by leaving the history of breakage of the connecting portion 420.

  The main control board assembly 200 according to the present invention may be an embodiment according to the example shown in FIG. This figure is a front view of the main control board assembly 200 mainly showing a portion where the seal seal 320 is covered by the seal cover member 400 ′.

  As shown in the figure, the sealing cover member 400 ′ is formed with a convex lens 402 as one or a plurality of enlarged display means so as to be integrated with the body of the sealing cover member 400 ′ that is fitted or transparent. The focal point (optical axis) of the convex lens 402 is the case lid 260 (protruding frame portion 266) to which the sealing seal 320 is stuck and the mounting bracket 300 in a state where the sealing cover member 400 ′ is mounted on the mounting bracket 300. It is located just on the boundary line with the sealing part 304 of. Further, the focal point of the convex lens 402 coincides with the sticking position of the seal sticker 320. In other words, the focal length of the convex lens 402 is set to coincide with the separation distance between the sticking surface (sealing surface 304a) of the sealing seal 320 or the cover portion main body 401 of the sealing cover member 400 ′.

  According to this embodiment, the surface state of the seal seal 320 can be enlarged and viewed through the convex lens 402, and the visual inspection can be facilitated. Therefore, even if the seal seal 320 is skillfully cut with a sharp blade, for example, as shown in the enlarged view EX shown in FIG. Findings can be made quickly and reliably. In addition, it is possible to facilitate visual confirmation of printed characters (for example, management information such as an identification number) on the seal sticker.

  The present invention can be applied not only to a main control board of a slot machine, but also to a sub control board and other game control boards, and also to a game control board of other game machines whose operation is controlled by a microcomputer such as a pachinko machine. .
