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

Further, the game control microcomputer and 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 from the game control microcomputer to the output circuit. The output data of is transmitted via a shared data bus.

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

The output circuits are all connected via a shared data bus, but some output circuits are directly connected to the game control microcomputer without going through the data bus and are shared.

Next, the game control board included in the game machine of the present invention will be described with reference to the following Examples 1 to 3.

The structure of the game control board in the first embodiment will be described. The game control board has a configuration in which electronic components are mounted on one surface, electronic components are not mounted on the other surface, and terminals provided by the electronic components are soldered. In the following, electronic components are mounted. The surface is called a mounting surface, and the surface on which electronic components are not mounted and the terminals of the electronic components are soldered is called a soldered surface.

FIG. 2 is a diagram showing a mounting surface of the game control board in this embodiment, and FIG. 3 is a diagram showing a solder surface of the game control board in this embodiment.
As shown in FIGS. 2 and 3, the game control board has a rectangular shape consisting of a pair of short sides extending in the vertical direction and a pair of long sides extending in the horizontal direction, and is composed of an insulating printed circuit board. .. Further, 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 composed of conductors so as to appropriately connect the through holes. A plurality of the above-mentioned wiring patterns are formed. Further, in the region where the wiring pattern of the mounting surface and the solder surface of the game control board is not formed, an insulating region made of an insulator and a conductor are formed, and a ground region forming a ground is formed. The ground region is a betta land formed over almost the entire area other than the region where the wiring pattern and the insulating region are formed on the mounting surface and the solder surface of the game control board.

As shown in FIG. 2, a wiring pattern extending in the vertical direction is arranged in a larger proportion than the wiring pattern extending in the horizontal direction on the mounting surface, while the wiring pattern extending in the horizontal direction is arranged horizontally on the solder surface 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. Therefore, the wiring patterns extending in the vertical direction are aggregated on the mounting surface, and the wiring patterns extending in the horizontal direction are aggregated on the solder surface, and when the wiring patterns extending in the vertical direction and the wiring patterns extending in the horizontal direction intersect. Designs such as bypassing wiring patterns can be reduced as much as possible.

Further, as shown in FIG. 3, since many wiring patterns arranged on the solder surface extend in the same lateral direction as the long side, the distance of the wiring pattern is longer than that of 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 the relatively long wiring pattern arranged on the solder surface is obstructed by the electronic component. Is being avoided.

Further, when the wiring pattern formed on the solder surface is branched, one of the wiring patterns at the branch destination is formed on the solder surface and the other is formed on the mounting surface through the through hole. Branching is performed without bypassing one wiring pattern or crossing one wiring pattern and the other wiring pattern at the branch destination on the same surface.

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

As shown in FIG. 4, electronic components such as the above-mentioned game control microcomputer, input circuit, and output circuit are mounted on the mounting surface of the game control board. These electronic components include an electronic component having one or more rows of terminals consisting of a plurality of terminals arranged in one direction. Most of the electronic components including these terminal rows are arranged along the long side of the game control board, that is, in the horizontal direction. As described above, on the mounting surface, the proportion of wiring patterns extending in the vertical direction is large, and the electronic components provided with the terminal rows are often arranged along the long side of the game control board, that is, arranged in the horizontal direction. By doing so, it is possible to connect to the terminal rows arranged in the horizontal direction as it is without changing the direction of the wiring pattern extending in the vertical direction.

Further, among the electronic components including the terminal train, the input circuit and the output circuit are formed in a rectangular shape as shown in FIG. 4, have a concave notch on one side on the short side, and have a model number on the surface. It is printed, and the orientation of the component can be specified by the orientation of the notch and the printing direction of the model number. Then, as shown in FIG. 4, the input circuit is arranged so that the notch is on the left side and the model number is printed in the direction from left to right in FIG. 4, while the output circuit is arranged in FIG. The notch is arranged to the right and the printing direction of the model number is from right to left, and these electronic components are either an input circuit or an output circuit depending on the position of the notch and the printing direction of the model number. It is possible to identify whether or not there is.

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

As described above, the game control board is formed with a data bus shared 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 this embodiment is composed of eight wiring patterns formed on the solder surface extending in the lateral direction, and is formed on the left side of the game control board as shown in FIG. It consists of eight wiring patterns formed so as to extend laterally toward the right side from the through hole to which the terminal of the mounted game control microcomputer is connected. As shown in FIG. 6, the data bus and electronic components such as input circuits and output circuits are connected by a wiring pattern formed so as to branch to the mounting surface side through a through hole and extend in the vertical direction. Will be done.

When connecting the game control microcomputer and electronic components such as input circuits and output circuits separated in the lateral direction via a data bus, first, the terminals of the game control microcomputer extend in the lateral direction. It is connected to the data bus on the surface, branches into a wiring pattern on the mounting surface side that extends vertically toward the electronic component through a through hole at the position where the electronic component is mounted, and is connected to the electronic component. Therefore, it is not necessary to bypass the wiring pattern branched from the data bus, and the game control microcomputer and the electronic components separated in the lateral direction can be efficiently connected. Further, since the wiring pattern constituting the data bus is formed on the solder surface on which the electronic components are not mounted, it is not easily affected by the noise from the electronic components on the data bus, and the data bus and the electronic components are through. Since they are connected by a wiring pattern branched to the mounting surface side through the hole, the wiring pattern on the mounting surface side is shortened, and the influence of noise from electronic components during this period is not easily affected.

As shown in FIG. 5, the wiring pattern extending in the lateral direction constituting the data bus is not formed in a straight line, but is divided into a plurality of wiring patterns extending in the lateral direction. The length of each divided wiring pattern (L1 to L8) is an antenna whose resonance is maximized according to the bus clock (frequency used when transmitting data on the data bus) when transmitting data on the data bus. It is formed shorter than the length (λ (bus clock) / 2). Therefore, the wiring pattern constituting the data bus has an antenna length corresponding to the bus clock, and it is possible to prevent unintended radio waves from being emitted due to resonance. Furthermore, even if the length is halved of the antenna length corresponding to the bus clock, it may be reflected on the surface of the substrate and strong resonance may occur. Therefore, the length of each divided wiring pattern (L1 to L8) are formed to have a length that is not 1/2 of the antenna length at which resonance is maximized according to the bus clock, and strong resonance occurs due to reflection on the surface of the substrate. It is also prevented from emitting radio waves.

Further, the bus clock differs depending on the game control microcomputer and the oscillator to be mounted, but the lengths (L1 to L8) of each divided wiring pattern depend on the bus clock which is the maximum frequency expected among them. It is formed so as to be shorter than the antenna length at which the resonance is maximized, and not to be half the antenna length at which the resonance is maximized according to the bus clock at the maximum frequency. Therefore, even when data is transmitted with a bus clock lower than the expected maximum frequency, it is possible to prevent unintended radio waves from being generated.

As shown in FIG. 5, the plurality of lateral wiring patterns constituting the data bus are diagonally right or diagonally left, that is, directions different from the directions of the plurality of lateral wiring patterns. It is connected with a wiring pattern extending to. Further, the wiring pattern in the horizontal direction and the wiring pattern in the diagonal right direction or the diagonal left direction, which are divided into a plurality of parts, are connected by being bent at an obtuse angle. Therefore, it is possible to prevent unintended radio waves from being emitted from the bent portion of the wiring pattern.

Further, as shown in FIG. 5, the wiring on the mounting surface side is passed through the through holes (A to F shown in FIG. 5) provided on the diagonal wiring pattern connecting the plurality of lateral wiring patterns. It is designed to branch into patterns (wiring patterns connected to A to F shown in FIG. 6), and a data bus is used by using a diagonal wiring pattern that connects a plurality of horizontal wiring patterns divided into each other. The wiring patterns that make up the above are branched.

In the game control board according to the first embodiment, in order to make the length of the horizontal wiring pattern shorter than the antenna length at which the resonance is maximized, the horizontal wiring pattern is divided into a plurality of wiring patterns, and a plurality of wiring patterns are divided into a plurality of wiring patterns. The horizontal wiring patterns divided into the above are connected by the diagonal wiring patterns formed on the same solder surface, but the plurality of horizontal wiring patterns are formed on the mounting surface side. As a configuration in which horizontal wiring patterns are connected by a separate wiring pattern, that is, horizontal wiring patterns are alternately formed on a solder surface and a 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 to branch at a position where the horizontal wiring pattern switches from the solder surface or the mounting surface to the other surface. With such a configuration, the wiring pattern after branching can be bypassed. , It is possible to branch the wiring patterns constituting the data bus without intersecting on the same plane.

FIG. 7 is a diagram showing the configuration of a ground region formed on the mounting surface of the game control board in this embodiment, and FIG. 8 is a configuration of a ground region formed on the solder surface of the game control board in this embodiment. It is a figure which shows.

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

Further, as shown in FIG. 7, electronic components such as a game control microcomputer, an input circuit, an output circuit, and the like to which a wiring pattern for transmitting a low voltage (Vcc (+ 5V) in this embodiment) signal is connected are connected. (Low-voltage component) is mounted in 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.
