The data is transmitted to the game control microcomputer to be used for controlling the game by the game control microcomputer.

  Further, as shown in FIG. 1, a plurality of output components such as a display, an LED, a motor, and a solenoid, which perform output control according to the progress of the game, are connected to the game control board. The output parts are, for example, a display for displaying according to the lottery result, a display for displaying the progress of the game and the state of the gaming machine, a display for instructing the player in an operation mode, a value owned by the player , An LED for indicating a game state, an LED for notifying the occurrence of an abnormality, a motor for operating a movable portion used for a game such as a reel or a variable winning device, a solenoid, and the like.

  As shown in FIG. 1, the game control board is provided with an output circuit for outputting an output signal to a corresponding output component based on output data transmitted from the game control microcomputer. The control microcomputer controls output components according to the progress of the game by transmitting output data to the output circuit.

  The game control microcomputer, the input circuit and the output circuit are connected via a data bus, and the input data is transmitted from the input circuit to the game control microcomputer and the game control microcomputer is output to the output circuit. Is transmitted via a shared data bus.

  Also, not all input circuits are connected via a common data bus, but some input circuits are directly connected to the game control microcomputer without passing through the data bus, and The input data to the microcomputer for game control is transmitted from the input circuit without going through the input circuit.

  The output circuits are all connected via a common data bus, but some output circuits are directly connected to the game control microcomputer without passing through the data bus, and The output data may be transmitted from the game control microcomputer to the output circuit without passing through the data bus.

  The data bus is connected to an external output terminal, so that output data from the game control microcomputer is output to an external device as an external output signal. It is possible to inspect the performance and the like of the gaming machine by using the output data output as.

  Next, a game control board included in the gaming machine of the present invention will be described using the following first to third embodiments.

  The structure of the game control board according to the first embodiment will be described. The game control board has a configuration in which an electronic component is mounted on one surface, an electronic component is not mounted on the other surface, and a terminal included in the electronic component is soldered. In the following, the electronic component is mounted. The surface is referred to as a mounting surface, and the surface on which the electronic components are not mounted and the terminals of the electronic component are soldered is referred to as a solder surface.

FIG. 2 is a view illustrating a mounting surface of the game control board according to the present embodiment, and FIG. 3 is a view illustrating a solder surface of the game control board according to the present embodiment.
As shown in FIGS. 2 and 3, the game control board has a rectangular shape including a pair of short sides extending in a vertical direction and a pair of long sides extending in a horizontal direction, and is configured by a printed board having an insulating property. . The game control board is formed with a plurality of through holes penetrating the mounting surface and the solder surface, and the mounting surface and the solder surface of the game control board are formed of a conductor so as to connect the through holes appropriately. A plurality of wiring patterns are formed. In addition, in a region where the wiring pattern is not formed on the mounting surface and the solder surface of the game control board, an insulating region formed of an insulator and a ground region formed of a conductor and forming a ground are formed. The ground area is a beta land formed over almost the entire area other than the area where the wiring pattern and the insulating area are formed on the mounting surface and the solder surface of the game control board.

  As shown in FIG. 2, on the mounting surface, more wiring patterns extending in the vertical direction are arranged than the ratio of wiring patterns extending in the horizontal direction. On the other hand, as shown in FIG. The wiring patterns extending in the direction are arranged more than the ratio of the wiring patterns extending in the vertical direction. For this reason, the wiring patterns extending in the vertical direction are concentrated on the mounting surface, and the wiring patterns extending in the horizontal direction are concentrated on the solder surface, and when the wiring pattern extending in the vertical direction intersects with the wiring pattern extending in the horizontal direction, Designs such as bypassing the wiring pattern can be reduced as much as possible.

  In addition, as shown in FIG. 3, the wiring pattern arranged on the solder surface has many wirings extending in the same horizontal direction as the long side, so that the distance of the wiring pattern is longer than the wiring pattern arranged on the mounting surface. However, as described above, the electronic component is mounted only on the mounting surface, and is not mounted on the solder surface, and a relatively long wiring pattern arranged on the solder surface is obstructed by the electronic component. That has been avoided.

  When the wiring pattern formed on the solder surface is branched, one of the branch wiring patterns is formed on the solder surface, and the other is formed on the mounting surface through a through hole. The wiring pattern is branched without detouring one wiring pattern or crossing one wiring pattern of the branch destination with the other wiring pattern on the same plane.

  FIG. 4 is a view showing a mounting surface in a state where the input circuit and the output circuit are mounted on the game control board in the present embodiment.

  As shown in FIG. 4, on the mounting surface of the game control board, electronic components such as the above-described game control microcomputer and input circuit and output circuit are mounted. These electronic components include electronic components in which a terminal row including a plurality of terminals arranged in one direction has one or more rows. Most of the electronic components having these terminal rows are arranged along the long side of the game control board, that is, in a lateral direction. As described above, on the mounting surface, the proportion of the wiring pattern extending in the vertical direction is large, and the electronic components including the terminal rows are often arranged along the long side of the game control board, that is, in the horizontal direction. By doing so, the wiring patterns extending in the vertical direction can be directly connected to the terminal rows arranged in the horizontal direction without changing the direction.

  As shown in FIG. 4, the input circuit and the output circuit among the electronic components including the terminal row are formed in a rectangular shape, and a concave notch is provided on one of the short sides, and the model number is provided on the surface. It is printed, and the direction of the component can be specified by the direction of the notch and the printing direction of the model number. Then, as shown in FIG. 4, the input circuit is arranged such that the notch is on the left side in FIG. 4 and the printing direction of the model number is from left to right, while the output circuit is Are arranged so that the notch faces right and the printing direction of the model number is from right to left, and these electronic components are input circuits or output circuits depending on the position of the notch and the printing direction of the model number. Is specified.

  FIG. 5 is a diagram showing a configuration of a data bus formed on a solder surface of the game control board in the present embodiment, and FIG. 6 is a wiring pattern branched from the data bus on a mounting surface of the game control board in the present embodiment. FIG.

  As described above, the game control board is formed with a data bus that is used for transmission of input data from the input circuit to the game control microcomputer and transmission of output data from the game control microcomputer to the output circuit. . The data bus formed on the game control board of the present embodiment is composed of eight wiring patterns extending in the horizontal direction formed on the solder surface. As shown in FIG. 5, the data bus is formed on the left side of the game control board. It consists of eight wiring patterns formed so as to extend in the horizontal direction toward the right from the through holes to which the terminals of the mounted game control microcomputer are connected. As shown in FIG. 6, the data bus and the electronic components such as the input circuit and the output circuit are connected to each other by a wiring pattern formed so as to branch to the mounting surface side through the through hole and extend vertically in the vertical direction. Is done.

  When the game control microcomputer and the electronic components such as the input circuit and the output circuit which are laterally separated from each other via the data bus as described above, first, the terminals of the game control microcomputer extend in the horizontal direction. At the position where the electronic component is mounted, the wiring is branched to a wiring pattern on the mounting surface extending in the vertical direction toward the electronic component at a position where the electronic component is mounted, and is connected to the electronic component. For this reason, it is not necessary to bypass the wiring pattern branched from the data bus, and the microcomputer for game control and the electronic components separated in the lateral direction can be efficiently connected. Also, since the wiring pattern forming the data bus is formed on the solder surface on which the electronic components are not mounted, the data bus is less susceptible to the noise from the electronic components. Since the connection is made by the wiring pattern branched to the mounting surface side through the hole, the wiring pattern on the mounting surface side is shortened, and the effect of noise from electronic components during this period is also reduced.

  As shown in FIG. 5, the wiring pattern extending in the horizontal direction that forms the data bus is not formed on a straight line, but is divided into a plurality of wiring patterns extending in the horizontal direction. The length of each of the divided wiring patterns (L1 to L8) depends on the bus clock at the time of transmitting data on the data bus (the frequency used when transmitting data on the data bus). It is formed shorter than the length (λ (bus clock) / 2). For this reason, the wiring pattern constituting the data bus has an antenna length corresponding to the bus clock, thereby preventing an unintended radio wave from being emitted due to resonance. Further, even when the length of the antenna becomes の of the antenna length corresponding to the bus clock, strong resonance may occur due to reflection on the surface of the substrate. The lengths (L1 to L8) are formed so as not to be な of the antenna length at which resonance is maximized in accordance with the bus clock, and strong resonance is generated by reflection on the surface of the substrate, Emission of radio waves is also prevented.

  The bus clock varies depending on the game control microcomputer and the oscillator to be mounted, but the length of each divided wiring pattern (L1 to L8) depends on the bus clock having the expected maximum frequency. The antenna is formed so as to be shorter than the antenna length at which the resonance is maximum, and not to be １ ／ of the antenna length at which the resonance is maximum according to the bus clock having the maximum frequency. For this reason, even when data is transmitted with a bus clock having a frequency lower than the assumed maximum frequency, generation of an unintended radio wave is prevented.

  As shown in FIG. 5, the horizontal wiring patterns divided into a plurality of parts constituting the data bus are diagonally rightward or diagonally leftward, that is, in a direction different from the direction of the plural divided horizontal wiring patterns. Are connected to each other with a wiring pattern extending therebetween. The plurality of divided horizontal wiring patterns and the diagonally right or diagonally left wiring pattern are bent and connected at an obtuse angle. For this reason, it is possible to prevent an unintended radio wave from being emitted from the bent portion of the wiring pattern.

  Also, as shown in FIG. 5, wiring on the mounting surface side is formed through through holes (A to F shown in FIG. 5) provided on diagonal wiring patterns connecting the plurality of divided horizontal wiring patterns. The data bus is branched into patterns (wiring patterns connected to A to F shown in FIG. 6), and uses a diagonal wiring pattern that connects a plurality of divided horizontal wiring patterns. Are branched.

  In the game control board according to the first embodiment, the horizontal wiring pattern is divided into a plurality of wiring patterns in order to make the length of the horizontal wiring pattern shorter than the antenna length at which resonance is maximized. In this configuration, the horizontal wiring patterns divided into two are connected by diagonal wiring patterns formed on the same solder surface, but the horizontal wiring patterns divided into a plurality are formed on the mounting surface side. In other words, the horizontal wiring pattern is alternately formed on the solder surface and the mounting surface so that the length of the horizontal wiring pattern is shorter than the antenna length at which resonance is maximized. Is also good. In such a configuration, it is preferable that the wiring pattern in the horizontal direction is branched at a point where the wiring surface is switched from the solder surface or the mounting surface to the other surface. With such a configuration, the branched wiring pattern can be bypassed. In addition, it is possible to branch the wiring pattern forming the data bus without crossing on the same plane.

  FIG. 7 is a diagram showing a configuration of a ground area formed on the mounting surface of the game control board according to the present embodiment, and FIG. 8 is a configuration of a ground area formed on a solder surface of the game control board according to the present embodiment. FIG.

  As shown in FIG. 7 and FIG. 8, a ground area is formed on almost the entire area other than the area where the wiring pattern and the insulating area are formed on the mounting surface and the solder surface of the game control board. The ground area formed on the game control board includes a first ground area and a second ground area which are electrically separated via an insulating area. On both the mounting surface and the solder surface, the first ground region is formed in the left region of the game control board, and the second ground region is formed in the right region of the game control substrate.

  Also, as shown in FIG. 7, electronic components such as a game control microcomputer, an input circuit, and an output circuit to which a wiring pattern to which a low-voltage (in this embodiment, Vcc (+5 V)) signal is transmitted are connected. The (low-voltage component) is mounted on the left region where the first ground region is formed, and the ground terminal of the low-voltage component is connected to the first ground region. On the other hand, an electronic component (high-voltage component) to which a wiring pattern for transmitting a high-voltage (in this embodiment, VLD (+24 V)) signal is connected, such as a drive circuit for operating a motor or a solenoid, is used. The ground terminal of the high-voltage component is mounted on the right region where the two ground regions are formed, and is connected to the second ground region. This prevents an unintended current from flowing from the high-voltage component to the low-voltage component through the ground region. In addition, since the first ground area and the second ground area are formed on the opposing sides of the game control board, respectively, even if a potential difference is temporarily generated, they are prevented from interfering with each other.

  In addition, as shown in FIG. 9, since a capacitor is provided between the first ground region and the second ground region, the capacitor temporarily connects between the first ground region and the second ground region. Current is prevented from flowing from one ground region to the other ground region even if a potential difference occurs in the first and second ground regions.

  As shown in FIGS. 7 and 8, an insulating region where no wiring pattern is formed between the first ground region and the second ground region is formed on the mounting surface and the solder surface.

Is again connected to the wiring pattern on the mounting surface side through the through hole, and to the terminal of the second input circuit.

  As described above, the first input circuit for detecting the input of the input signal from the relatively low-importance first input component among the input components used for controlling the game includes the game control microcomputer and the data control bus via the data bus. On the other hand, the second input circuit that detects the input of the input signal from the second input component that is more important than the first input component while being connected is not connected to the data bus, and directly without passing through the data bus. The input data based on the input signal from the second input component is transmitted to a data bus through which input data and output data to an output circuit are transmitted from another input circuit. Since the data is transmitted to the game control microcomputer without any intervention, the input data based on the important input signal may affect the input data from other input circuits and the output data to the output circuit.

  Although the second embodiment of the present invention has been described above, the present invention is not limited to the second embodiment, and includes changes and additions without departing from the gist of the present invention. Needless to say. Further, the same or similar configuration as the first embodiment has the same effect as that described in the first embodiment. Further, the modification illustrated in the first embodiment is also applicable to the second embodiment.

  The structure of the game control board according to the third embodiment will be described. The game control board has a configuration in which the electronic component is mounted on one surface and the electronic component is not mounted on the other surface, and the terminals of the electronic component are soldered, as in the first and second embodiments.
