In addition, the door 120 is provided with a display substrate 141, an inverter substrate 142 that turns on a fluorescent lamp (not shown), and a front substrate 140 formed in a “U” shape in order from the top. The front substrate 140 is connected to the main substrate 130 by a wire harness 150 made of a flat cable.
Other substrates and wire harnesses are omitted for easy understanding.

FIG. 6 is a schematic block diagram of the main part of the slot machine according to the conventional example.
In the figure, the main board 130 is connected to the power board 132, the drum board 133, and the front board 140 so as to be able to input / output, and is connected to the external terminal board 134 and the sub-control board 135 so as to be able to output.
The slot machine 100 includes various substrates, sensors, switches, and the like in addition to the above-described substrates, but are omitted for easy understanding.

The power supply board 132 receives a setting key switch signal for setting a lottery probability such as a big hit from the setting key switch 131 and outputs it to the main board 130.
Further, the drum substrate 133 outputs a drum position signal to the main substrate 130 and inputs a rotation pulse signal.

  However, in the slot machine 100 according to the conventional example, although the main board 130 is housed in the fraud prevention case 130a that is a colorless and transparent corner, it is provided at an unsightly position of the casing 110, so that visual inspection is easy. In other words, there is a problem in that it cannot be performed with high accuracy and fraudulent acts cannot be effectively suppressed. In other words, even if an unauthorized means is attached to the main board 130 or the like, it cannot be detected, so that the illegal act cannot be effectively controlled.

Further, the illegal act on the slot machine 100 is not limited to the ROM exchange described above.
For example, as a fraudulent act related to the start signal, a fraudulent act such as outputting a random start signal from the electronic device to the main board 130 at a predetermined timing to control the random number lottery timing and win a special game state such as a big hit. is there. In this fraudulent act, a false start signal is input from the wire harness 150, but fraudulent means attached to the back surface of the wire harness 150 made of a flat cable cannot be easily found and cannot be effectively prevented. There was a problem.

  Further, as a fraudulent act related to the key switch signal for setting, there is a fraudulent act of changing the setting so as to win a special game state such as a big hit with a high probability by outputting a high-probability setting signal to the main board 130. . This fraud has a problem that it can be easily crafted because a wire harness (not shown) connecting the power supply board 132 and the main board 130 is exposed.

  The present invention is considered in view of the above circumstances, and the main board is provided on the back surface of the door, and the main board is directly connected to the front board, thereby eliminating the wire harness related to fraud. Alternatively, it is an object to provide a fraud prevention type slot machine that reliably prevents fraudulent acts on the wire harness.

In order to achieve this object, a tamper-proof slot machine according to the present invention is a gaming machine that controls a game operation in a slot machine that includes a housing and a door that is openably and closably attached to the front side of the housing. A main board for control is provided on the back surface of the door, and the main board is directly connected to a front board for controlling operation means, display means, etc. disposed in front of the door. .
In this way, there is no need to provide a wire harness for transmitting signals from the front board to the main board, or the length of the wire harness can be greatly shortened. Can be reliably prevented. Further, when the door is opened, the main board is in a position where it can be easily seen. Therefore, the main board can be easily and accurately visually inspected, and illegal acts on the main board can be effectively prevented.

In addition, the present invention provides a wire harness that transmits a predetermined input signal related to fraud among input signals that are input to a main board for game control that controls game operations, from wire harnesses related to other signals. The configuration is provided independently.
In this way, the wire harness related to fraud can be separated from other wire harnesses, for example, it can be a wire harness composed of several cables, and the wire harness related to fraud can be efficiently inspected. be able to.

Further, the present invention is configured such that an input signal related to the illegal act is a serial signal.
If it does in this way, the number of cores of the wire harness related to a fraudulent act can be further reduced, and the inspection to a wire harness can be performed still more efficiently.

Moreover, this invention is set as the structure which installed the rotation reel and the hopper in the housing | casing.
In this way, since the space with the door opened is widened, visual inspection of the main board and the front board can be improved, and illegal acts can be more effectively prevented.

In the present invention, the front substrate and the main substrate are configured as a single unified substrate.
If it does in this way, since it becomes unnecessary to provide the wire harness for transmitting a signal from a front board to a main board, illegal acts to a wire harness can be prevented effectively.

Moreover, this invention is set as the structure which accommodated at least the part corresponded to the said main board | substrate among the said unified board | substrates in the fraud prevention case.
If it does in this way, a fraudulent act can be prevented effectively with respect to the part corresponded to a main board | substrate.

In the present invention, a gaming state setting means is mounted on the main board or the front board.
If it does in this way, since it is not necessary to output a game state setting signal via a wire harness, the fraudulent act with respect to a wire harness can be prevented.

Moreover, this invention is set as the structure which provided the said main board | substrate so that rotation was possible so that the front and back of this main board | substrate could be visually observed.
In this way, since it is possible to easily perform a visual inspection on the front and back surfaces of the main board, it is possible to efficiently control fraud.

  As described above, according to the tamper-proof slot machine according to the present invention, it seems that the main board is provided on the back surface of the door so that it is possible to easily carry out fraud. However, when the door is opened, the main board can be easily seen. As a result, the main board can be visually inspected easily and accurately, and illegal acts on the main board can be effectively prevented. Further, by directly connecting the main board to the front board, it is possible to eliminate the wire harness related to the fraud and reliably prevent the fraud against the wire harness. Furthermore, the independence of the wire harness related to the fraud can reliably prevent the fraud against the wire harness.

[First embodiment]
FIG. 1 shows a schematic perspective view of the main part for explaining the mounting state of the main board of the slot machine according to the first embodiment of the present invention.
In the figure, a fraud prevention type slot machine 1 (hereinafter abbreviated as “slot machine 1” as appropriate) including a casing 110 and a door 120 that is attached to the front side of the casing 110 so as to be openable and closable. Compared to the slot machine 100 of the example, a game control main board 30 for controlling the game operation is provided on the back surface of the door 120, and operation means and display means (see FIG. The difference is that the front board 40 and the main board 30 for controlling the control board etc. are directly connected via connectors 41 and 33. Other configurations are almost the same as those of the conventional slot machine 100.
Therefore, in FIG. 1, the same components as those in FIG. 6 are denoted by the same reference numerals, and detailed description thereof is omitted.

The main board 30 is attached to the lower right side of the door 120 in a state of being housed in a colorless and transparent tamper-proof case 32. The main board 30 is mounted with a connector 33 exposed from the fraud prevention case 32, and the connector 33 is connected to a connector 41 mounted on the front board 40. This eliminates the need to provide a wire harness for transmitting a signal from the front substrate 40 to the main substrate 30, so that, for example, illegal acts on the wire harness 150 in the conventional slot machine 100 can be reliably prevented. it can.
In this embodiment, the main board 30 and the front board 40 are directly connected via the connectors 33 and 41. However, the present invention is not limited to this configuration. For example, a gold tab (see FIG. (Not shown), and the gold tab may be directly connected to the connector mounted on the main board 30.

  Here, it is preferable that the rotating reel 111, the power supply unit 112, and the hopper 113 are installed in the housing 110. In this way, since the space with the door 120 opened is widened, visual inspection of the main board 30 and the front board 40 can be improved, and illegal acts can be more effectively prevented.

More preferably, the main board 30 may be configured to include a setting key switch 131 as a gaming state setting unit. In this way, the gaming state setting signal (setting key switch signal) is transmitted by the circuit disposed on the main board 30, and there is no need to provide an externally exposed wire harness for transmitting the gaming state setting signal. Therefore, fraudulent acts on the wire harness can be effectively prevented.
In the present embodiment, the setting key switch 131 is mounted on the main board 30. However, the present invention is not limited to this. For example, the setting key switch 131 may be mounted on the front board 40.

As described above, in the slot machine 1 of the present embodiment, when the door 120 is opened, the main board 30 is in a position where it can be easily seen. Therefore, the main board 30 can be visually inspected easily and accurately. Actions can be effectively prevented. Moreover, since it is not necessary to provide a wire harness for transmitting a signal from the front substrate 40 to the main substrate 30, for example, an illegal act on the conventional wire harness 150 can be reliably prevented.
The slot machine 1 has no wire harness 150 for connecting the main board 30 and the front board 40 as compared with the slot machine 100 of the conventional example. However, as shown in FIG. 133, the wire harness (not shown) for connecting the external terminal board 134 and the sub-control board 135 and the main board 30 becomes long. However, since these wire harnesses are not related to fraudulent acts, they are advantageous for fraudulent acts. Never do.

[Second Embodiment]
FIG. 3 is a schematic perspective view of a main part for explaining the slot machine according to the second embodiment of the present invention.
In the figure, a fraud prevention type slot machine 1a (referred to as a slot machine 1a as appropriate) includes a game control main board 30 for controlling a game operation as compared with a conventional slot machine 100, and a door 120. Further, a wire harness 50a for transmitting a predetermined input signal related to fraud among input signals input to the main board 30 is provided independently from the wire harness 52 related to other signals. The point is different. Other configurations are almost the same as those of the conventional slot machine 100.
Therefore, in FIG. 3, the same components as those in FIG. 5 are denoted by the same reference numerals, and detailed description thereof is omitted.

  The main board 30 is mounted with a setting key switch 31 as game state setting means. In addition, the main board 30 includes a wire harness 50a that transmits a predetermined input signal related to fraud among the input signals input to the main board 30, such as a start signal, a game state setting signal, and each rotation stop signal. It is provided independently from the wire harness 52 that transmits a signal that is not related to fraud. If it does in this way, the wire harness 50a relevant to an illegal act can be isolate | separated from the other wire harness 52, for example, it can be set as the wire harness 50a which consists of several (5) cables, and is visually compared with a flat cable. Since inspectability improves, the inspection with respect to the wire harness 50a related to a fraudulent act can be performed efficiently.

  Preferably, the input signal related to the illegal act is a serial signal instead of transmitting three rotation stop signals in parallel from three cables, and three rotation stop signals serially from one cable. It is good to be the structure which transmits. If it does in this way, the number of cores of the wire harness related to an illegal act can be reduced further, it can be set as the wire harness 50a which consists of three cables, and the inspection with respect to the wire harness 50a related to an illegal act is further It can be done efficiently.

The main board 30 is attached to the upper part of the door 120 in a state of being housed in a colorless and transparent tamper-proof case 32a.
Here, preferably, the main board 30 may be provided in the vicinity of the front board 40 provided on the back surface of the door 120. In this manner, the wire harnesses 50a and 52 for connecting the front board 40 and the main board 30 are provided. Since it becomes short, while there exists an effect which suppresses the fraud with respect to the wire harness 50a, the wire harness 50a can be visually inspected easily, and the fraud with respect to the wire harness 50a can be prevented effectively.
In addition, visual inspection property can be improved by exposing the wire harness 50a.

  More preferably, a hinge (not shown) is provided below the fraud prevention case 32a, and the main board 30 is provided so as to be rotatable downward. In this way, the locking means (not shown) for holding the fraud prevention case 32a upward is released, and the main board 30 is rotated downward, so that the front and back surfaces of the main board 30 can be easily and Visual inspection can be performed with high accuracy, and illegal acts on the back surface of the main board 30 can be effectively prevented.

As described above, in the slot machine 1a of the present embodiment, when the door 120 is opened, the main board 30 is in a position where it can be easily seen. Therefore, the main board 30 can be visually inspected easily and accurately. Actions can be effectively prevented.
Moreover, since the back surface is not formed like the flat cable because the wire harness 50a related to the illegal act is composed of several cables instead of the flat cable, it becomes impossible to provide an improper means to hide the back surface. At the same time, visual inspection can be improved, and illegal acts on the wire harness 50a can be effectively suppressed.
In the present invention, connecting the main board 30 directly to the front board 40 includes a case where a short wire harness 50a is used as in the present embodiment.

[Third embodiment]
FIG. 4 is a schematic perspective view of the main part for explaining the slot machine according to the third embodiment of the present invention.
In the figure, a fraud prevention type slot machine 1b (referred to as a slot machine 1b as appropriate) is connected to the main board 30 and the front board 40 as compared with the slot machine 1 of the first embodiment. The difference is that a single unified substrate 300 in which these are integrally formed is provided. Other configurations are substantially the same as those of the slot machine 1 of the first embodiment.
Therefore, in FIG. 4, the same components as those in FIG. 1 are denoted by the same reference numerals, and detailed description thereof is omitted.

The unified substrate 300 includes a front substrate portion 40b and a main substrate portion 30b, and the main substrate portion 30b is integrally protruded from the lower portion of the front substrate portion 40b. In this case, it is not necessary to provide connection means such as a connector for connecting the main board portion 30b and the front board portion 40b, so that the manufacturing cost can be reduced.
In the present embodiment, since the main board portion 30b is housed in the fraud prevention case 32b, fraudulent acts can be effectively prevented with respect to the main board portion 30b.

  Thus, since the slot machine 1b does not need to provide a wire harness for connecting the main board part 30b and the front board part 40b, it is possible to effectively prevent an illegal act on the wire harness.

  The fraud prevention type slot machine of the present invention has been described with reference to the preferred embodiment, but the fraud prevention type slot machine according to the present invention is not limited to the above-described embodiment, and the scope of the present invention. Needless to say, various modifications can be made.

  For example, the slot machine 1a is configured to serialize and transmit three reel stop signals serially from one cable instead of transmitting three reel stop signals in parallel from three cables. The signal to be performed is not limited to three reel stop signals. For example, signals related to fraud and major signals may be digitized (encrypted). In this way, in order for fraudsters to operate the slot machine illegally, the digitization rules must be set first. It is necessary to analyze this, and if the manufacturer uses a plurality of rules at random, this analysis becomes almost impossible and fraud can be prevented.

  In addition, the slot machines 1, 1a, and 1b of each embodiment can be combined with the effective configurations of the other embodiments as long as they can be tolerated. In this way, illegal acts can be prevented more reliably. Or it can be suppressed.

  The fraud prevention type slot machine of the present invention is not limited to slot machines, and is widely applicable to objects that need to prevent fraudulent acts on the circuit board from the outside as well as game machines such as pachinko machines. It is possible to apply.
