Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a locking structure for a substrate case that houses an electronic circuit board that controls gaming operations and the like of a gaming machine.
[0002]
[Prior art]
Most of game machines such as ball game machines such as pachinko machines, pinball game machines and smart ball game machines, and slot machines are controlled by electronic circuits using microcomputers. Normally, this electronic circuit includes electronic components such as a central processing unit (CPU) that performs general arithmetic control, a storage element (RAM) that can read and write data, and a storage element (ROM) that can only read data. Is provided. The CPU uses these RAM and ROM to control the operation of the ball ball game machine and the reel of the slot machine.
[0003]
The probability of jackpot occurrence in this type of gaming machine is performed by random lottery. That is, the random number generated by the random number generator is sampled, and the winning mode is determined depending on which section of the winning determination table the sampled random number value falls within. The winning determination table is made up of data that divides a predetermined range of random numbers into each winning manner, and is stored in the ROM. The CPU generates a jackpot if the sampled random number value belongs to, for example, the A section of the winning determination table, generates a jackpot if it belongs to the B section, and if it belongs to the C section, Let's lose.
[0004]
The ROM that stores data such as the probability of jackpot occurrence is detachably attached to the electronic circuit board and can be replaced. By replacing the ROM, it is possible to easily configure control circuit boards of different game models using the same electronic circuit board.
[0005]
FIG. 8 shows a typical pachinko machine 1 having a conventional board case mounting structure. FIG. 8 (a) is a front view of the pachinko machine 1, and FIG. 8 (b) is a rear view thereof.
[0006]
A game board 2 is provided inside the front door in front of the pachinko machine 1. A number of obstacle nails are planted in the game board 2, and a center accessory (not shown) is arranged in the center. When the handle 3 is turned, the game balls stored in the upper plate 4 are driven into the game board 2. The game balls that have been driven into the game board 2 flow down the board surface while being bounced by the obstacle nails, and if they do not enter any of the winning openings, they are collected from the out openings.
[0007]
On the other hand, when the game balls enter the general winning opening, a predetermined number of game balls are paid out to the upper plate 4. Further, when a game ball wins at the start opening provided in the center of the front, the variable display device provided in the center accessory starts to rotate. When the variable display device stops displaying a predetermined symbol, a big win occurs, and the variable winning device (attacker) remains open for a predetermined time or until a predetermined number of game balls are won. Therefore, when a big hit occurs, the player can acquire a large amount of game balls in a short time.
[0008]
In addition, when the variable display device stops displaying another predetermined symbol, the probability variation state occurs, and the jackpot is very likely to occur. The jackpot occurrence probability in this probability variation state is predetermined according to the combination of symbols stopped and displayed on the variable display device, and is set to a jackpot occurrence probability value that is extremely higher than that in the normal gaming state.
[0009]

[0020]
[Problems to be solved by the invention]
However, in the above-described conventional board case mounting structure for gaming machines, the board case is fixed by the claws 21 and screws 22 or the like. Therefore, the inside of the substrate case can be easily opened by removing the claws and screws. For this reason, even while the hall is open, the ROM may be removed from the inside of the board case and replaced with an illegally modified ROM, or the electronic circuit board itself may be replaced with an illegally modified electronic circuit board. If the ROM or the electronic circuit board is illegally replaced in this way, data such as the jackpot occurrence probability stored in the ROM or the electronic circuit board is falsified, and a large number of game balls, medals and the like are stolen.
[0021]
[Means for Solving the Problems]
The present invention has been made to solve such a problem, and includes a lower case that houses an electronic circuit board on which electronic components are mounted, an upper case that covers the lower case, and the board case. A first fixing tool that is mounted and is fixed to the base so that one end and the other end are exposed at both sides of the substrate case, and one end is rotatably supported by one end of the first fixing tool. A second fixture that pivots about the portion and covers the substrate case placed on the first fixture, and that fixes the substrate case to the base so as to face the first fixture; A locking device that locks the other end of the fixing device to the other end of the first fixing device, and a fixing that is positioned between the substrate case or the second fixing device and the base body, and fixes the first fixing tool to the base body. The board case locking structure of the gaming machine was constructed from the means.
[0022]
In this configuration, the substrate case is placed on the first fixture fixed to the base, and the second fixture is rotated around one end of the substrate case so as to be covered with the substrate case and fixed to the base. The In this state, when the other end of the second fixture is locked to the other end of the first fixture, the substrate case is sandwiched between the opposing first and second fixtures and locked therebetween. The
[0023]
Since the fixing means for fixing the first fixing tool to the base, for example, the screw is located between the substrate case or the second fixing tool and the base, the locking tool is unlocked and the base case or the second fixing tool moves. The fixing means cannot be removed unless it is done. Therefore, unless the locking tool is unlocked, the first fixing tool cannot be removed from the base body, and the substrate case is kept locked between the first and second fixing tools. That is, the upper case and the lower case are integrated, and the upper case cannot be opened.
[0024]
And a second lower case that houses a second electronic circuit board on which electronic components are mounted, and a second upper case that covers the second lower case, and is adjacent to the first board case. A second substrate case to be attached to the substrate, a first fixing means for fixing the second upper case to the second lower case, a covering portion for covering the first fixing means, and an attachment portion to be fixed to the base body And a second fixing means positioned between the first fixing tool and the base, the fixing part being fixed to the base in a state where the covering part is covered with the first fixing means. The board case locking structure of the gaming machine is configured.
[0025]
According to this configuration, in a state where the first substrate case is locked to the first fixing tool and the second fixing tool, the second substrate case is further locked to the base body by the third fixing tool. That is, since the second fixing means for fixing the mounting portion of the third fixing tool to the base, for example, the screw is located between the first fixing tool and the base, the third fixing tool is the first fixing tool. Unless removed, it is kept fixed to the substrate. Since the first fixing tool cannot be removed unless the locking tool is unlocked as described above, the third fixing tool cannot be removed unless the locking tool is unlocked. Further, since the covering portion of the third fixing member covers the first fixing means, for example, a screw, for fixing the second upper case to the second lower case, the first fixing means is the third fixing means. It will not come out unless the tool is removed. That is, the second upper case cannot be removed from the second lower case unless the third fixture is removed.
[0026]
The first fixing means for fixing the second upper case to the second lower case is configured to simultaneously fix the second electronic circuit board to the second board case, so that the second board case accommodates the second upper case. The second electronic circuit board thus made becomes more difficult to take out.
[0027]
Also, a substrate case composed of a lower case for storing an electronic circuit board on which electronic components are mounted and an upper case that covers the lower case, and one end of the substrate case are rotatably supported by the base body. Then, the second fixing tool for covering the substrate case placed on the base and fixing the base case to the base, and the locking tool for locking the other end of the second fixing tool to the base, are used. A substrate case locking structure was constructed.
[0028]
In this configuration, the substrate case is placed on the base, and the second fixture is rotated around one end of the substrate case so as to be covered with the substrate case and fixed to the base. When the other end of the second fixture is locked to the base in this state, the substrate case is sandwiched between the base and the second fixture and locked therebetween.
[0029]
As an aspect in which the substrate case is fixed to the base by the second fixing tool, for example, there is an aspect in which a groove formed in the upper case of the substrate case is used. When the second fixing tool is fitted into the groove, the substrate case is hooked on the second fixing tool, and the movement in the direction parallel to the base is restricted and fixed to the base.
[0030]
Further, as another aspect in which the substrate case is fixed to the base body by the second fixing tool, an aspect in which one end portion of the substrate case is detachably accommodated and both side portions are rotatably supported by the base body is used. There is also. When the second fixture is fixed to the base body at a distance from the container, the substrate case is placed between the first and second fixtures with one end of the substrate case being received in the container. The substrate case is locked and the rotation of the substrate case by the container is restricted, and the substrate case is fixed to the base.
[0031]
DETAILED DESCRIPTION OF THE INVENTION
Next, a first embodiment in which the board case locking structure of the gaming machine according to the present invention is applied to the pachinko machine 1 shown in FIG. 8 described above will be described.
[0032]

[0033]
The box-shaped first substrate case 51 and the second substrate case 52 are provided on the back surface of the pachinko machine 1, and the first substrate case 51 includes the first substrate case 6 and the second substrate case 2 shown in FIG. The substrate case 52 corresponds to the second substrate case 8 described above.
[0034]
The first board case 51 includes a lower case 51a that houses the game board 56, and an upper case 51b that covers the lower case 51a. A second substrate case 52 is provided adjacent to the first substrate case 51. The second board case 52 includes a second lower case 52a that houses an electronic circuit board 57 that controls the operation and the like of the handle 3, and a second upper case 52b that covers the second lower case 52a. Become. The outer periphery of the second lower case 52a is slightly larger than the outer periphery of the second upper case 52b.
[0035]
One end of the first substrate case 51 is accommodated in the connector bracket 15 shown in FIGS. 9 and 10 described above. The connector bracket 15 constitutes a container that detachably accommodates one end of the first substrate case 51. As described above, both side portions of the connector bracket 15 are rotatably supported by the rear panel unit 5 by the bracket supporters 16a and 16b.
[0036]
On the other hand, the other end of the first substrate case 51 is fixed to the pachinko machine frame 7 by a first fixing tool 53 and a second fixing tool 54. The other end portion of the conventional first substrate case 6 is locked to the claw 21 (see FIG. 10) erected on the rear panel unit 5, but in the present embodiment, the first substrate case 51 is the conventional first substrate case 51. The other end of the first substrate case 51 reaches the pachinko machine frame 7 longer than the substrate case 6.
[0037]
The second substrate case 52 is fixed to the pachinko machine frame 7 below the first substrate case 51 by a third fixture 55.
[0038]
The side view of the first fixture 53 is shown in FIG. 4 (a), and the plan view thereof is shown in FIG. 4 (b). The first fixture 53 is fixed to the pachinko machine frame 7 by inserting screws 58 to 61 into the screw holes 53a to 53d. The heads of the screws 58 to 61 are located between the second fixture 54 and the pachinko machine frame 7, and the heads of the screws 59 to 61 are the lower case 51 a in the first substrate case 51. And the pachinko machine frame 7. The first fixture 53 is fixed to the pachinko machine frame 7 at a distance from the connector bracket 15.
[0039]
The other end of the first board case 51 with one end housed in the connector bracket 15 is tilted toward the first fixture 53 fixed to the pachinko machine frame 7. Is opposed to the rear panel unit 5 and the pachinko machine frame 7. One end and the other end of the first fixture 53 are exposed on both sides of the first substrate case 51 placed in this way.
[0040]
A pin hole 53e (see FIG. 4A) is opened at one end of the first fixture 53, and a pin hole opened at one end of the second fixture 54 is fitted to the pin hole 53e. A pin 62 is inserted. The other end of the second fixture 54 is supported so as to be rotatable about the pin 62 in the D direction (see FIGS. 1B and 3). The second fixture 54 rotates around the pin 62 and covers the other end portion (see FIG. 1C) of the first substrate case 51 whose surface is lowered by one step. The first substrate case 51 is fixed to the pachinko machine frame 7 so as to face the surface.
[0041]
A key cylinder 63 that is a locking tool is provided at the other end of the second fixing tool 54. The engaging portion 63 a of the key cylinder 63 is fitted into a hole 53 f (see FIG. 4B) opened at the other end of the first fixing member 53, and the key 64 is inserted into the key groove 63 b of the key cylinder 63. When the key 64 is rotated in the E direction (see FIGS. 1A and 2), the engaging portion 63a is locked across the hole 53f. That is, the other end of the second fixture 54 is locked to the other end of the first fixture 53.
[0042]
FIG. 5A shows a side view of the third fixture 55, and FIG. 5B shows a plan view thereof. The third fixing device 55 is formed by sheet metal processing in the same manner as the first fixing device 53 and the second fixing device 54, and has a mounting bent portion 55 a fixed to the pachinko machine frame 7, and a screw 65. , 66 covering covering curved portions 55b, 55c.
[0043]
The screws 65 and 66 fix the second upper case 52b to the second lower case 52b. Further, the screw 65 penetrates the end of the electronic circuit board 57 and is screwed into the second lower case 52 a, and at the same time, the electronic circuit board 57 is fixed to the second board case 52.
[0044]
The head of the screw 65 protrudes from the surface of the second upper case 52b that is lowered by one step, and is covered by the covering curved portion 55b. The head of the screw 66 protrudes from the surface of the ear 52c formed integrally with the second upper case 52b, and is covered with the covering curved portion 55c. The ear portion 52c protruding around the second upper case 52b is fitted into an ear receiving portion 52d that protrudes around the second lower case 52a and is integrally formed with the second lower case 52a. Yes.
[0045]
The mounting bent portion 55a is fixed to the pachinko machine frame 7 by inserting screws 67 and 68 into screw holes 55d and 55e opened at the ends thereof. The heads of these screws 67 and 68 are located between the end of the first fixture 53 and the pachinko machine frame 7.
[0046]
The third fixture 55 is formed with a vertical bending restricting curved portion 55f and a horizontal bending restricting curved portion 55g. The vertical bending restricting curved portion 55f has a tip embedded under the second lower case 52a, and the third fixture 55 extends in the z direction (see FIG. 1B) perpendicular to the pachinko machine frame 7. Restricts bending. That is, even if the third fixing tool 55 is to be raised in the vertical direction, the third bending tool 55 is not bent in the vertical direction because the vertical bending restricting curved portion 55f is caught by the second substrate case 52. Without the vertical bending restricting curved portion 55f, the third fixture 55 is bent in the vertical direction around the mounting portion 55a.
[0047]
Further, the bent portion 55g for horizontal bending regulation has its tip inserted into the gap between the ear portion 52c and the ear receiving portion 52d, and is in the y direction horizontal to the pachinko machine frame 7 (see FIG. 1 (a)). The third fixture 55 is restricted from being bent. That is, even if it is going to bend the 3rd fixing tool 55 in a horizontal direction, since the bending part 55g for horizontal bending restrictions is hooked on the 2nd board | substrate case 52, the 3rd fixing tool 55 does not bend in a horizontal direction. Without the horizontal bending restricting curved portion 55g, the third fixture 55 is bent in the horizontal direction around the attachment portion 55a.
[0048]
Since the third fixing tool 55 is fixed to the pachinko machine frame 7 at one end of the mounting portion 55a, the other end of the third fixing tool 55 may be bent. Since there is the portion 55f and the horizontal bending restricting curved portion 55g, such anxiety is eliminated.
[0049]
In the substrate case locking structure according to the present embodiment described above, the first substrate case 51 is placed on the first fixture 53 fixed to the pachinko machine frame 7, and the second fixture 54 has the pin 62. It pivots to the center and is covered by the first substrate case 51. In this state, the other end of the second fixture 54 is locked to the other end of the first fixture 53 by the key cylinder 63, and the first substrate case 51 is opposed to each of the first and second fixtures. It is clamped between 53 and 54 and locked between them.
[0050]
Since the screws 58 to 61 for fixing the first fixing member 53 to the pachinko machine frame 7 are located between the first lower case 51a or the second fixing member 54 and the pachinko machine frame 7, the key cylinder 63 is disengaged. The screws 58 to 61 cannot be removed unless the first lower case 51a and the second fixture 54 are moved by being locked. Therefore, unless the key cylinder 63 is unlocked, the first fixing member 53 cannot be removed from the pachinko machine frame 7, and the first substrate case 51 is locked between the first and second fixing members 53, 54. It is kept in the state. That is, the first lower case 51a and the first upper case 51b are integrated, and the first upper case 51b cannot be opened.
[0051]
Further, since the first board case 51 is locked between the first and second fixing members 53 and 54 in a state in which one end portion is accommodated in the connector bracket 15, the first board case 51 is provided with the first board case 51. The rotation operation of the substrate case 51 is restricted, and the first substrate case 51 is fixed to the rear panel 5 and the pachinko machine frame 7.
[0052]
Since the other end portion of the conventional first board case is simply fixed by engaging with the claws, the first board case can be easily formed by removing the claws and standing the first board case with the connector bracket 15. Although it could be removed from the rear panel 5, in the present embodiment, the first substrate case 51 cannot be removed from the back surface of the pachinko machine 1 unless the key cylinder 63 is unlocked. Accordingly, conventionally, the game board 56 is simply taken out from the first board case, and the taken-out game board 56 is entirely replaced with an illegally modified game board, or the ROM on the taken-out game board 56 is illegal. In some cases, the ROM is replaced with a modified ROM. However, according to the above-described substrate case locking structure according to the present embodiment, it is possible to prevent such unauthorized replacement.
[0053]
In the present embodiment, the first substrate case 51 is locked to the first fixture 53 and the second fixture 54, and the second substrate case 52 is further moved by the third fixture 55. Locked to the pachinko machine frame 7. That is, since the screws 67 and 68 for fixing the attachment portion 55a of the third fixing tool 55 to the pachinko machine frame 7 are located between the first fixing tool 53 and the pachinko machine frame 7, the third fixing tool 55 is provided. Is kept fixed to the pachinko machine frame 7 unless the first fixture 53 is removed. Since the first fixture 53 cannot be removed unless the key cylinder 63 is unlocked by the key 64 as described above, the third fixture 55 cannot be removed unless the key cylinder 63 is unlocked.
[0054]
Further, since the covering portions 55b and c of the third fixing tool 55 cover the screws 65 and 66 for fixing the second upper case 52b to the second lower case 52a, the screws 65 and 66 are the third screws. The fixing tool 55 cannot be removed unless it is removed. That is, the second upper case 52b cannot be removed from the second lower case 52a unless the third fixing tool 55 is removed. Therefore, the second electronic circuit board 57 accommodated in the second board case 52 cannot be taken out unless the key cylinder 63 is unlocked, and therefore the electronic components mounted on the second electronic circuit board 57 are illegally replaced. It is possible to prevent the second electronic circuit board 57 itself from being illegally replaced with an illegally modified electronic circuit board.
[0055]
Further, the screw 65 fixes the second upper case 52 b to the second lower case 52 a and simultaneously fixes the second electronic circuit board 57 to the second board case 52. Therefore, the second electronic circuit board 57 accommodated in the second board case 52b is more difficult to take out.
[0056]
Next, a second embodiment in which the board case locking structure of the gaming machine according to the present invention is applied to the pachinko machine 1 described above will be described. FIG. 6 (a) is a plan view showing a substrate case locking structure of the pachinko machine 1 according to the second embodiment, FIG. 6 (b) is a front view thereof, and FIG. 6 (c) is an essential part of FIG. FIG. In the figure, the same parts as those in FIG.
[0057]
The board case locking structure according to the second embodiment is mainly different from the first embodiment described above in that the shape of the first board case 51 in the first embodiment described above is different. That is, in the present embodiment, a groove 71 is formed in the upper case 51 b ′ constituting the first substrate case 51. The second fixture 54 is fitted in the groove 71. Further, the first fixing tool 53 and the second fixing tool 54 are provided near the center of the first board case 51, but are arranged at a distance from the connector bracket 15.
[0058]
Since the second fixture 54 and the groove 71 are fitted in this way, the first substrate case 51 is caught by the second fixture 54 and the movement in the direction parallel to the pachinko machine frame 7 is restricted. ing. For this reason, the first substrate case 51 is more firmly fixed to the pachinko machine frame 7. Therefore, for example, even if the connector bracket 15 is broken and removed, the first board case 51 cannot be pulled out in the horizontal direction.
[0059]
Next, a third embodiment in which the board case locking structure of the gaming machine according to the present invention is applied to the pachinko machine 1 described above will be described. FIG. 7A is a plan view showing the substrate case locking structure of the pachinko machine 1 according to the third embodiment. FIG. 7B is a front view thereof, and FIG. It is a principal part fracture side view. In the figure, the same parts as those in FIG.

【The invention's effect】
As described above, in the board case locking structure of the gaming machine according to the present invention, the fixing means for fixing the first fixing tool to the base body is located between the lower case or the second fixing tool and the base body. The fixing means cannot be removed unless the lower case or the second fixing tool is moved. Therefore, unless the locking tool is unlocked, the first fixing tool cannot be removed from the base body, and the substrate case is kept locked between the first and second fixing tools.
[0070]
Further, since the fixing means for fixing the attachment portion of the third fixing tool to the base body is located between the first fixing tool and the base body, the third fixing tool is the base body unless the first fixing tool is removed. It is kept in a fixed state. Moreover, the covering portion of the third fixing member covers fixing means for fixing the second upper case to the second lower case. Therefore, this fixing means cannot be removed unless the third fixture is removed, and the second upper case cannot be removed from the second lower case.
[0071]
For this reason, by locking the second fixture to the first fixture, the second substrate case can be locked to the base simultaneously with the first substrate case.
[0072]
At this time, the fixing means for fixing the second upper case to the second lower case is configured to simultaneously fix the second electronic circuit board to the second board case, so that the second board case accommodates the second upper case. The second electronic circuit board thus made becomes more difficult to take out.
[0073]
Further, when the substrate case is placed directly on the base body, the second fixing tool rotates around the one end and is covered by the substrate case, and in this state, the other end of the second fixing tool is the base body. When being locked, the substrate case is sandwiched between the base body and the second fixture and locked therebetween.
[0074]
According to the present invention as described above, the ROM is removed from the inside of the board case and replaced with an illegally modified ROM, or the electronic circuit board itself is replaced with an illegally modified electronic circuit board during the operation of the hall. It is prevented.
