SEALING STRUCTURE OF P.C.B RECEIPT BOX FOR PACHINKO MACHINE}

The present invention relates to a sealing structure of a substrate storage box in a pinching machine.

One type of pachinko is called a hit when a pattern that is variablely displayed on the variable display device is stopped by a predetermined pattern. In general, such a circuit board is provided with a circuit board having a CPU or the like for controlling the variable display device. The circuit board is housed in a substrate storage box mounted on the rear surface of the organic panel. The substrate storage box is composed of a case on the fixed side and a case on the cover side covered with the case. However, the case is required to be closely monitored in order to prevent unauthorized modification. For this purpose, the sealing paper is stuck to the surface where both cases merge together conventionally.

However, even if it is a sealed species, the possibility of peeling as it is without tearing cannot be completely denied. Conventionally, the only evidence for the seal is the presence or absence of the cutting of the seal paper, and if the situation in which the seal paper is exquisitely peeled off, it was immediately exposed to the risk of tampering. Therefore, a means for achieving more safety of sealing is desired.

The present invention was devised and devised in view of the above-mentioned conventional problems, and an object thereof is to provide a sealing structure capable of reliable sealing.

The invention of claim 1 for achieving the above object is an interior of both cases by a fixed side case for fixing a circuit board for controlling an organic operation and a cover side case that matches the fixed side case. A structure for sealing and storing the circuit board in a space between the cover side case and the fixed side case in a space in which the circuit board is accommodated, and at the same time, an end portion of the control piece is placed in both cases. It is characterized in that both cases are sealed by taking out from at least one of the openings and sealing the end by heating.

According to the invention of claim 1, the control piece is placed between the cases on the cover side and the fixed side in the case, and the tip end is removed from the opening formed in the case and heated to be in close contact with each other. Even if the regulation piece resists, the sealing state of the case is maintained. That is, since the case cannot be opened unless the heat-sealed portion is broken or cut, it can be clearly seen that the seal has been released due to the breakage or the like.

EMBODIMENT OF THE INVENTION Hereinafter, one Embodiment which actualized the sealing structure of the board | substrate storage box in the pachinko machine of this invention is demonstrated with reference to FIGS.

First, the outline of the pachinko is briefly described. In FIG. 10 showing the front of the pachinko, the frame 12 is fitted into the front frame 11 of the pachinko, and the lower opening portion of the opening of the frame 12 is the front plate 13. Blocked by And the front plate 13 is provided with an upper support plate 14 for storing the batting and supplying the batting to the batting device not shown. Moreover, the window frame 15 is fitted in the upper opening part of the opening of the metal frame 12, and the transparent plate glass 16 is inserted in it.

Further, in the lower part of the front plate 13, the underlay plate 17 for storing the granular beads and the handle 18 for manipulating the other shot mechanism are provided in the front frame 11.

And the organic panel 19 shown in FIG. 9 is attached to the back side of the said front frame 11. As shown in FIG. As a result, an organic region is formed in the window frame 15. That is, various granular bead storage devices, variable display devices, decorative lamps, and the like are disposed on the front surface of the organic panel 19. Also, the granular bead assembly cover 20 is mounted on the rear surface of the organic panel 19, and the substrate storage box 21 having the sealing structure of the present invention is installed there. Therein, the control circuit board 22 such as the variable display device is sealed in a sealed structure so as not to be tampered with.

The substrate storage box 21 is composed of a fixed side case 23 for fixing the circuit board 22 and a cover side case 24 covering the circuit board 22, as shown in FIG. As shown in Fig. 2, the fixed side case 23 is made of a rectangular metal steel plate, and boss portions 25 (metal) are placed in four corners thereof. Screw holes are formed in the boss portions 25, and the screws 26 (made of metal) can be clamped thereto. One long side part (edge part near the 2nd middle part) in this fixed side case 23 is formed slightly bent upwards, and the board | substrate clamping part 28 is formed in the substantially center part of the bent wall 27. Is formed. The substrate holding portion 28 is composed of a pair of substrate holding portions 29 and 29 and a substrate pressing portion 30 disposed therebetween, and the substrate holding portion 29 slightly covers a predetermined portion of the bent wall 27. After protruding upward, it is formed to bend inward. The substrate pressing portion 30 also protrudes a part of the bent wall 27 in the same manner as the substrate holding portion 29, and is formed to be bent inwardly, but slightly higher than the substrate holding portion 29. One edge portion of the circuit board 22 is inserted and supported by the difference in the protruding height between the substrate holding portion 29 and the substrate pressing portion 30. In addition, the long side portion (the second edge, the inner edge portion) opposite to this is slightly bent upwards in the same manner, and a long and elongated locking hole 32 is formed in the portion extending from the bent wall 31 to the bottom plate 46. ) Are formed at appropriate intervals.

On the other hand, the cover side case 24 is formed by bending downward the periphery of the metal steel plate which forms a rectangular shape as shown in FIG. The length of the long side of the cover side case 24 is equal to the length of the side to which the fixed side case 23 corresponds, and the length of the short side is formed to be shorter than the side to which the fixed side case 23 corresponds. In addition, the front and rear both side walls (right and left side of the 3rd middle part) of the covering side case 24 protrude so that the near edge in the same figure may become equal to the horizontal width of the fixed side case 23, Outlets 24a and 24a are formed. In addition, mounting pieces 37 and 37 are bent to the inside of both of the elongated pieces 24a at edges of the near side wall shown in the covering side case 24, respectively. A mounting hole 37a is formed in the mounting piece 37, and the position of each mounting hole 37a is a state in which the cover side case 24 is covered with the fixed side case 23 as described later (shown in FIG. 7). State) is a position to be matched to both boss portions 25 on one side (left side of the seventh middle) of the fixed side case 23, respectively. In addition, on the side wall (side wall closest to the middle part 4) which is opposite to the mounting piece 37 in the cover side case 24, four locking pieces are located in the lower edge part (the upper part edge part in the 4th way). 38 is arrange | positioned at the space | interval corresponding to the said locking hole 32. As shown in FIG. The locking piece 38 is formed by bending the long side portion inward from the side of the side wall, and fixes the cover side case 24 in an open position (posture shown in FIG. 6) approximately 90 ° with respect to the fixed side case 23. It is fitted from below the locking hole 32 of the side case 23. Further, the cover side case 24 can then be rotated in the direction (the arrow direction in FIG. 6) covered with the fixed side case 23 while the locking piece 38 is engaged with the locking hole 32. FIG. .

In addition, a plurality of slits 43 and the like are opened in the upper surface portion of the covering side case 24 with the rectangular large window hole 39 as the center thereof. On the other hand, the closing plate 40 made of plastic is attached to the back side of the cover side case 24 so as to close each opening. However, the closing plate 40 is used to be transparent so that the inside of the case can be seen through each opening. More specifically, blocking the opening 39 with the transparent closing plate 40 is the type number of the ROM (read only memory) installed on the circuit board 22 accommodated in the substrate storage box 21 (for example, This is because the serial number or the version number) can be confirmed through the expanse 39. Moreover, although the some slit 48 is formed also in the side wall of the long side of the covering side case 24, since these function as a heat radiation hole, they cannot be prevented with the closing plate 40 about them. On the left and right inner wall surfaces of the covering side case 24, a pair of counting index portions 41 are arranged before and after each for mounting the closing plate 40, and simultaneously embossed inward to form the counting index portions.

On the other hand, the closing plate 40 is large enough to cover the back side of the upper wall surface of the cover side case 24, and has a shape suitable for the R portion over the wall surface on the long side. In addition, the locking piece portions 42 protrude from the left and right edge portions of the closing plate 40 in correspondence with the respective locking index portions 41. Then, when the closing plate 40 is overlaid to cover the window 39, the slit 43, and the like on the back side of the cover side case 24, the respective engagement piece portions 42 are engaged with the engagement index portion 41, respectively. As a result, the closing plate 40 is held in a state of blocking the window 39 or the like (see FIG. 5).

In addition, a circular through hole 44 is formed in one corner (upper left side of the third middle) on the upper surface of the covering side case 24, and similarly, the closing plate 40 is also positioned at the position to match the through hole 44. The through hole 45 is formed. By using the through holes 44 and 45, the cover side case 24 is provided with a kiss switch 50 (see FIG. 7). The key switch 50 can be operated from the outside of the box 21 in a state where the circuit board 22 is accommodated in the board storage box 21. By operating this, the probability of hitting can be changed, for example. . In addition, a plurality of small holes 49 are formed in the closing plate 40 at positions where the slits 43 are matched, and they function as heat radiating holes similar to the slits 48 by matching with the slits 43.

Next, the sealing structure will be described. That is, in the center part of the bending wall 31 of the fixed side case 23, and the center part of one short side part (right edge of the 2nd middle) in the fixed side case 23, protruding pieces 33 and (, 34 is formed to be bent upward. The protruding piece 33 protrudes higher than the bent wall 31, and the engaging hole 33a formed in the shape of a long hole is punched in the center. In addition, each of the above-mentioned protrusions is provided at the center side of the side wall (the side closest to the fourth middle side) and the one short side portion (the right side middle edge of the fourth side) opposite to the side where the mounting piece 37 is provided in the cover side case 24. Corresponding to the pieces 33 and 34, the nodules 35 and 36 are formed. Then, when the cover side case 24 is closed, the protruding pieces 33 and 34 formed on the fixed side case 23 at the nodal portions 35 and 36 are formed so as to be matched with one surface.

In addition, as shown in FIG. 11, a regulation piece (the side of the long side part (side of the side which matches the side in which the nodular part 35 in the coating side case 24 was formed) of the closing plate 40) 51 is formed to be torsionally deformed downward. A locking protrusion 51a that can be fitted to the locking hole 33a almost suitably is formed on the outer side of the lower end portion of the restricting piece 51. The position of the locking projection 51a is a position that is disposed almost at the center of the nodule 35 when the closing plate 40 is mounted on the back side of the covering side case 24, and the covering side case 24 is closed. In this case, it is a position to be fitted to each other by the engagement hole 33a which is drilled in the protruding piece 33 of the fixed side case 23. Further, the protruding length of the locking protrusion 51a is set to a length at which the tip is slightly protruded from the outer surface of the protruding piece 33 in a state of being fitted to the locking hole 33a, and the protrusion can be heat sealed. It is supposed to be.

In addition, the circuit board 22 has a slightly smaller rectangular shape than the fixed side case 23, and fixing holes 22a are formed at positions corresponding to the bosses 25 in the four corners. Print wiring is performed on the circuit board 22, and a plurality of electrical components such as a CPU and a ROM are soldered. In addition, although not shown, the lamp | ramp which comprises the gland of a circuit is formed around each fixing hole 22a.

The procedure for storing and sealing the circuit board 22 in the substrate storage box 21 will be described. First, the circuit board 22 is superimposed on the fixed side case 23, and the edge portion (the sixth left edge) of the circuit board 22 is supported by the substrate clamping portion 28, and one side (the 6 Fix the fixing hole 22a of the right side in the middle to the boss | hub part 25. Further, in this state, the cover side case 24 is opened at approximately 90 ° with respect to the fixed side case 23, and the locking piece 38 of the cover side case 24 is locked to the fixed side case 23. (32) from below (see Figures 1 and 6). Then, the cover side case 24 is rotated in the direction (the directions indicated by the arrows in FIGS. 1 and 6) of the covering side case 24 with the locking piece 38 engaged with the locking hole 32. Let's do it.

At this time, the restricting piece 51 is bent inward with the finger from the outside of the covering side case 24 via the nodule 35 (see FIG. 12), and the lid of the covering side case 24 is closed. It enters inside of the protrusion piece 33 of the fixed side case 23 with rotation (refer FIG. 13). Then, the curving piece 51 curved with the rotation of the covering side case 24 gradually returns to its original state by the elastic force, and the locking piece 51a rides over the upper edge of the protruding piece 33 and protrudes 33. Move inside of. Then, when the cover side case 24 is in a state where the regular lid is closed with respect to the fixed side case 23, the restricting pieces 51 are stacked on each other on the inner surface of the protruding piece 33, and the locking protrusion 51a is formed. The fitting hole 33a of the protruding piece 33 is fitted. As a result, the edge of the engagement protrusion 51a attached to the cover side case 24 is protruded out of the substrate storage box 21 through the engagement hole 33a of the fixed side case 23.

Then, the screw 26 is inserted into the mounting hole 37a and the fixing hole 22a, and the cover side case 24 and the other side of the circuit board 22 are fastened together to the boss portion 25 and locked. The part which protrudes out of the box 21 of the protrusion 51a is heat-sealed (refer FIG. 14). In addition, the sealing paper 47 is attached to the mating surface of the protruding piece 34 and the nodule 36, and the sealing paper 47 is also placed on the mating surface of the protruding piece 33 and the nodule 35. A portion of the heat seal is attached so as to cover it (see Fig. 15). Thereby, the circuit board 22 is accommodated in the board | substrate storage box 21, and is sealed with the control piece 51 and the sealing paper 47. As shown in FIG.

As described above, in the present embodiment, the regulating piece 51 extends from the cover side case 24 to the fixed side case 23 in the substrate storage box 21, and the front end portion is formed on the fixed side case 23. Since it protrudes from the hole 33a and heat-seals it, even if it tries to open the box 21 as it is, the regulation piece 51 resists this and does not destroy or cut | disconnect the heat-sealing part of the regulation piece 51. You can't open it unless you can. Therefore, the sealing state of the board | substrate storage box 21 is hold | maintained reliably. In addition, when the heat-sealed portion is broken or cut, it can be clearly seen that the seal is released due to breakage or the like. In addition, a sealing paper 47 is attached to the mating surface of the fixed side case 23 and the cover side case 24. In particular, one sealing paper 47 is attached so as to cover a part of the heat-sealed portion. In order to break a part, since sealing paper 47 needs to be peeled off, sealing becomes a double structure, and the board | substrate storage box 21 can be prevented from being opened illegally more reliably.

The present invention can be modified in various ways, and the following modifications are included in the technical scope of the present invention.

(1) In the present embodiment, any of the cases 23 and 24 on the fixed side and the cover side is made of metal, but the case on the cover side may be made of resin. It may be.

(2) In addition, the control piece 51 does not necessarily need to be integrally formed from the closing plate 40, but may be formed by itself. In this case, it is necessary to be fixable to the inner surface of the case by suitable means. For example, the restriction piece may be taken out of the fixed side case and heat-sealed on the outer surface of the covering side case.

(3) An opening may be provided in either case on the fixed side or the covering side to heat seal both sides.

In addition, this invention can be implemented in various changes within the range which does not deviate from the summary.
