  An embodiment for implementing a gaming machine according to the present invention will be described.

The gaming machine in the embodiment of the present invention is a pachinko gaming machine or a slot machine installed in a game hall or the like, and in particular, as shown in FIG. 1, a gaming control microcomputer for controlling a game is mounted. A game control board.

As shown in FIG. 1, the game control board is connected to a plurality of input components such as various switches and sensors for detecting an input state corresponding to the progress of the game. Input components include, for example, a detection switch for detecting an operation by a player, a detection switch for detecting the passage of a game medium such as a game ball or a medal, a sensor for specifying a position of a movable object used in a game such as a reel, a player Detection switches used for various settings such as the degree of advantage, and detection switches for detecting door opening and abnormalities.

Further, as shown in FIG. 1, the game control board is equipped with an input circuit for detecting an input signal from these input components, and an input for specifying the detection status of the input signal from the input component by the input circuit. The data is transmitted to the game control microcomputer and used for game control by the game control microcomputer.

Further, as shown in FIG. 1, a plurality of output components that perform output control according to the progress of the game, such as a display, an LED, a motor, and a solenoid, are connected to the game control board. The output parts include, for example, a display that displays according to the lottery result, a display that displays the progress of the game and the state of the gaming machine, a display that instructs the player on the operation mode, and the value owned by the player Indicator to display,
An LED that indicates a gaming state, an LED that notifies the occurrence of an abnormality, a motor that operates a movable part used in a game such as a reel or a variable winning device, a solenoid, and the like.

Further, 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 transmits the output data to the output circuit to control the output components according to the progress of the game.

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

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

The output circuits are all connected through a shared data bus, but some output circuits are directly connected to the game control microcomputer without going through the data bus. The configuration may be such that output data is transmitted from the game control microcomputer to the output circuit without going 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 the external device as an external output signal. It is possible to check the performance of the gaming machine using the output data output as.

Next, game control boards provided 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 in 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. Hereinafter, the electronic component is mounted. The surface is referred to as a mounting surface, and the surface on which the electronic component is not mounted and the terminals included in the electronic component are soldered is referred to as a solder surface.

FIG. 2 is a diagram illustrating a mounting surface of the game control board in the present embodiment, and FIG. 3 is a diagram illustrating a solder surface of the game control board in 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 the vertical direction and a pair of long sides extending in the horizontal direction, and is configured by a printed board having insulating properties. . The game control board is formed with a plurality of through holes that penetrate the mounting surface and the solder surface, and the mounting surface and the solder surface of the game control board are made of a conductor so that the through holes are appropriately connected. A plurality of wiring patterns are formed. In addition, in a region where the wiring pattern on 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 constituting the ground is formed. The ground region is a solid ground formed over almost the entire region 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, the mounting surface has more wiring patterns extending in the vertical direction than the proportion of the wiring patterns extending in the horizontal direction. On the other hand, as shown in FIG. More wiring patterns extending in the direction than the ratio of wiring patterns extending in the vertical direction are arranged. For this reason, the wiring pattern extending in the vertical direction is concentrated on the mounting surface, the wiring pattern extending in the horizontal direction is concentrated on the solder surface, and the wiring pattern extending in the vertical direction intersects with the wiring pattern extending in the horizontal direction. The design such as bypassing the wiring pattern can be reduced as much as possible.

Also, as shown in FIG. 3, the wiring pattern arranged on the solder surface has many wirings extending in the same lateral direction as the long side, and therefore the wiring pattern distance 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 disposed on the solder surface is obstructed by the electronic component. It has been avoided.

Also, when branching the wiring pattern formed on the solder surface, one of the branch destination wiring patterns is formed on the solder surface, and the other is formed on the mounting surface through the through hole. One of the wiring patterns is bypassed, and the branching is performed without crossing the one wiring pattern and the other wiring pattern on the same plane.

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 the present embodiment.

As shown in FIG. 4, electronic components such as the above-described 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 in which a terminal row including a plurality of terminals arranged in one direction includes one row or a plurality of rows. And most of the electronic components provided with these terminal rows are arranged along the long side of the game control board, that is, in the 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. As a result, it is possible to connect to the terminal rows arranged in the horizontal direction without changing the direction of the wiring pattern extending in the vertical direction.

In addition, as shown in FIG. 4, the input circuit and the output circuit of the electronic component 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 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. As shown in FIG. 4, the input circuit is arranged so 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 shown in FIG. Are arranged so that the notch is facing right and the printing direction of the model number is the direction 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. It can be specified whether or not there is.

FIG. 5 is a diagram showing a configuration of the data bus formed on the solder surface of the game control board in the present embodiment, and FIG. 6 shows a wiring pattern branched from the data bus on the 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 commonly 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 this embodiment is composed of eight wiring patterns extending in the lateral direction formed on the solder surface.
As shown in FIG. 5, it consists of eight wiring patterns formed so as to extend laterally from the through hole to which the terminal of the game control microcomputer mounted on the left side of the game control board is connected to the right side. . 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 in the vertical direction in the vertical direction. Is done.

When the game control microcomputer and the electronic components such as the input circuit and the output circuit that are separated in the lateral direction are connected via the data bus in this way, first, the terminal of the game control microcomputer extends in the lateral direction. It is connected to the data bus on the surface, branches to a wiring pattern on the mounting surface side extending in the vertical direction toward the electronic component through the through hole 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 gaming control microcomputer and the electronic components separated in the lateral direction can be efficiently connected. In addition, since the wiring pattern constituting the data bus is formed on the solder surface on which no electronic component is mounted, it is not easily affected by noise from the electronic component to the data bus. 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 it is difficult to be affected by noise from electronic components during this time.

As shown in FIG. 5, the wiring pattern extending in the horizontal direction constituting 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 divided wiring pattern (L1 to L8) is an antenna whose resonance is maximized according to the bus clock (frequency used when data is transmitted on the data bus) when data is transmitted on the data bus. It is 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, and it is prevented that an unintended radio wave is emitted due to resonance. Further, even when the antenna length corresponding to the bus clock is ½ of the antenna length, strong resonance may occur due to reflection on the surface of the substrate. Therefore, the length of each divided wiring pattern (L1 to L8) is 1/2 of the antenna length at which the resonance becomes maximum according to the bus clock.
It is formed in such a length that it does not become, and strong resonance is generated by reflection on the surface of the substrate, and emission of radio waves is also prevented.

Also, the bus clock differs depending on the game control microcomputer and oscillator to be mounted, but the length of each divided wiring pattern (L1 to L8) depends on the bus clock that has the maximum frequency expected. The antenna length is shorter than the antenna length at which the resonance is maximum, and further, the length is not ½ 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, unintended radio waves are prevented from being generated.

As shown in FIG. 5, the plurality of horizontal wiring patterns constituting the data bus are diagonally rightward or diagonally left, that is, different from the direction of the horizontal wiring pattern divided into a plurality. Are connected with a wiring pattern extending between the two. Also, the horizontal wiring pattern divided into a plurality and the diagonal right direction or diagonal left direction wiring pattern are bent and connected at an obtuse angle. This prevents 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 made through through holes (A to F shown in FIG. 5) provided on the diagonal wiring patterns that connect the plurality of divided horizontal wiring patterns. A data bus is formed by branching into patterns (wiring patterns connected to A to F shown in FIG. 6), and using diagonal wiring patterns that connect a plurality of divided horizontal wiring patterns. The wiring pattern that constitutes is 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. The horizontal wiring patterns divided into two are connected by an oblique wiring pattern formed on the same solder surface, but the divided horizontal wiring patterns are formed on the mounting surface side. As a configuration in which 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 the resonance is maximum. Also good. In such a configuration, it is preferable to branch at a place where the horizontal wiring pattern is switched from the solder surface or the mounting surface to the other surface. By such a configuration, the wiring pattern after branching can be bypassed. Thus, the wiring pattern constituting the data bus can be branched without intersecting on the same plane.

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 a first electrically separated through an insulating region.
A ground region and a second ground region are formed. In 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 board.

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

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 places the first ground region and the second ground region between them. Even if a potential difference occurs, current is prevented from flowing from one ground region to the other ground region.

As shown in FIGS. 7 and 8, the mounting surface and the solder surface have a first ground region and a second ground region.
An insulating region in which no wiring pattern is formed is formed between the ground region and the first ground region and the second ground region are electrically separated. Furthermore, the first ground region and the second ground region on the mounting surface, and the first ground region and the second ground on the solder surface.
The ground region is formed so as to overlap with the insulating region separating the first ground region and the second ground region on the mounting surface, and the first ground region and the second ground on the solder surface.
Since the insulating regions separating the ground regions are also formed so as to overlap, even if a potential difference is temporarily generated from one surface of the mounting surface and the solder surface to the other surface, they are prevented from interfering with each other. It has become.

The wiring pattern connected to the terminal provided in the first is provided at a location where the wiring pattern is first connected to the electronic component. For this reason, it is possible to connect from the solder surface to the wiring pattern on the mounting surface using a through hole for connecting to the electronic component.

As shown in FIGS. 12A and 12B, the game control board is attached to the gaming machine in a state of being housed in the board case. The substrate case can be sealed by a one-way screw, a sealing seal, welding, or the like, and once sealed, it is difficult to open without leaving a trace.

FIG. 13 is a circuit diagram relating to the supply of backup power to the game control microcomputer mounted on the game control board in this embodiment.

As shown in FIG. 13, Vcc (+5 V) is generated by the power supply board and is connected to the power supply input terminal Vcc of the game control microcomputer mounted on the game control board. Further, Vcc (+5 V) branches from a line supplied to the game control microcomputer on the power supply board, and is connected to the charging capacitor via the backflow prevention diode. The backflow prevention diode, the charging capacitor, Is connected to the backup power supply input terminal VBB of the game control microcomputer.

While power is being supplied, Vcc (+5 V) is supplied as a driving power source for the game control microcomputer and the charging capacitor is charged. On the other hand, when the supply of power is stopped, the supply of Vcc (+5 V) is stopped so that the backup power supply VBB charged in the charging capacitor is supplied to the game control microcomputer. The game control microcomputer is supplied with a backup power supply VBB, so that data stored in a RAM included in the game control microcomputer is held. In the present embodiment, the backup power is supplied from a power supply board outside the game control board, but may be supplied from a circuit provided in the game control board.

FIG. 14 is a diagram showing a power supply wiring pattern formed on the solder surface of the game control board in this embodiment, and FIG. 15 is a wiring pattern formed on the mounting surface of the game control board in this embodiment. It is a figure which shows the relationship between the wiring pattern for power supply formed in the soldering surface.

As shown in FIG. 14, on the solder surface of the game control board, there are wiring patterns Vcc1 to Vcc1 for supplying normal power and wiring patterns VBB for supplying backup power as wiring patterns constituting a power supply line. Is formed. The wiring patterns Vcc1 to Vcc1 are shown in FIG.
As shown in FIG. 4 and FIG. 15, the wiring pattern is formed on the solder surface and the wiring pattern is formed on the mounting surface, and is connected to the electronic component mounted on the game control board. On the other hand, as shown in FIG. 14, the wiring pattern VBB is composed only of the wiring pattern formed on the solder surface. That is, the wiring pattern VBB is not connected to the wiring pattern formed on the mounting surface, but is connected to the backup power supply input terminal VBB of the game control microcomputer only through the wiring pattern formed on the solder surface. That is, the wiring pattern VBB supplied with the backup power VBB from the power supply board is formed only on the solder surface. For this reason, the wiring pattern VBB supplied with the backup power supply VBB does not need to bypass the electronic components mounted on the mounting surface, and the distance of the wiring pattern to the game control microcomputer can be shortened. It is hard to receive, and RA by noise
The data stored in M is prevented from being damaged.

Further, as shown in FIG. 15, a solid ground is formed on a portion of the mounting surface where the wiring pattern VBB is formed on the solder surface side. Therefore, the noise is blocked by the solid ground formed on the mounting surface, so that the wiring pattern VBB on the solder surface side is not easily affected by the noise. Also, as shown in FIG. 15, among the wiring patterns formed on the solder surface, the wiring pattern VBB that supplies the backup power is more on the mounting surface side than the wiring patterns Vcc1 to Vcc1 that supply the normal power. In the region where the wiring pattern is formed, the wiring pattern formed on the mounting surface side, in particular, the wiring pattern used for signal transmission is formed at a position where the number of points intersecting is small. For this reason, the influence of noise on the wiring pattern VBB supplied with the backup power from the wiring pattern used for transmission of the signal formed on the mounting surface side is suppressed as much as possible.

FIG. 20 is a diagram showing the configuration of the data bus formed on the solder surface of the game control board in this embodiment, and FIG. 21 shows the wiring pattern branched from the data bus on the mounting surface of the game control board in this embodiment. FIG.

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 extending in the lateral direction formed on the solder surface. As shown in FIG. 20, on the left side of the game control board. It consists of eight wiring patterns formed so as to extend laterally from the through hole to which the terminal of the mounted game control microcomputer is connected to the right side. As shown in FIG. 21, the data bus, the input circuit, and the output circuit are connected to each other by a wiring pattern that branches to the mounting surface side through a through hole and extends in the vertical direction in the vertical direction.

When the game control microcomputer and the input circuit and the output circuit that are separated in the lateral direction are connected via the data bus in this way, first, the data bus on the solder surface in which the terminals of the game control microcomputer extend in the lateral direction first. To the wiring pattern on the mounting surface side that extends vertically to the input circuit or output circuit through the through hole at the position where the input circuit or output circuit is mounted, and connected to the input circuit or output circuit It becomes. Therefore, it is not necessary to bypass the wiring pattern branched from the data bus, and the gaming control microcomputer can be efficiently connected to the input circuit and the output circuit that are separated in the lateral direction. Also,
Since the wiring pattern constituting the data bus is formed on the solder surface on which the electronic component is not mounted, it is not easily affected by noise from the electronic component to the data bus, and the data bus, the input circuit, and the output circuit are Since the connection is made by the wiring pattern branched to the mounting surface side through the through hole, the wiring pattern on the mounting surface side is shortened, and it is difficult to be affected by noise from electronic components during this time.

Further, as shown in FIG. 22, the data bus is connected to a noise removal circuit at a position closer to the game control microcomputer than any input circuit and output circuit connected to the data bus. The noise on the data bus is less likely to affect the game control microcomputer.

Further, as shown in FIG. 20, the game control board is mounted with connectors CN10 to CN17 for connecting wiring from outside the game control board in the vicinity of the upper side in the figure, and constitutes a data bus. The wiring pattern is formed in a region near the lower side in the figure of the game control board, that is, a region near the other side facing one side where the connectors CN10 to CN17 are mounted. For this reason, the connector CN10 is used to input / output signals to / from electronic components outside the game control board.
A region where electronic components such as an input circuit and an output circuit are mounted between the CN 17 and the data bus is widely secured.

As shown in FIG. 20 and FIG. 21, the game control board has an input signal from a first input component that is relatively less important among input components used for game control (sensors and switches that do not trigger lottery). A first input circuit that detects an input of a detection signal and the like, and an input signal from a second input component that is more important than the first input component (a detection signal of a sensor or switch that triggers a lottery, and an advantage are defined. A second input circuit for detecting the input of a detection signal for changing a set value), a first operation for operating a movable part such as a solenoid or a motor according to the progress of the game, based on output data from the game control microcomputer A first output circuit that outputs an output signal to the output component, and a second display that displays various displays, LEDs, etc. according to the progress of the game based on output data from the game control microcomputer The second output circuit that outputs an output signal to the power component, the game machine mounted on the game control board based on the output data from the game control microcomputer, and the payout rate when the game is played in a certain period A third output circuit that outputs an output signal to a performance indicator that displays the performance of the above is mounted.

Among these input circuits and output circuits, the first output circuit, the first output circuit, the second output circuit, and the third output circuit are connected to a data bus, and transmission of input data and transmission of output data are performed via the data bus. Done.

As shown in FIG. 20, the wiring pattern constituting the data bus connected to the terminals of the game control microcomputer on the solder surface branches to the mounting surface side through the through holes at a plurality of locations, and extends vertically on the mounting surface. It is connected to the formed wiring pattern. As shown in FIG. 21, the wiring pattern branched to the mounting surface side through the through hole at the position M in the figure is the first.
Connected to the input circuit terminals. Further, the wiring pattern branched to the mounting surface side through the through hole at the position N in the figure is connected to the terminal of the third output circuit. In addition, the wiring pattern branched to the mounting surface side through the through holes at positions O and P in the drawing is connected to the terminals of the first output circuit.
In addition, the wiring pattern on the mounting surface side connected through the through hole at the position Q in the figure is the second
Connected to the terminals of the output circuit and branched on the mounting surface. Some wiring patterns are connected to the external output terminals as they are, and the remaining wiring patterns are soldered through the through holes once at the position R in the figure. Is connected to the wiring pattern on the mounting surface side through the through hole again at the position S in the figure and connected to the external output terminal.

As shown in FIGS. 20 and 21, the input circuit of the input circuit and the output circuit connected by the common data bus has a shorter wiring pattern length to the game control microcomputer than the output circuit. Connected to the data bus. For this reason, input data used for game control is not easily affected by noise or the like.

Further, as shown in FIGS. 20 and 21, the output signal is output to the first output component that operates the movable part according to the progress of the game among the plurality of output circuits connected by the common data bus. The one output circuit has data so that the length of the wiring pattern to the game control microcomputer is shorter than the second output circuit that outputs an output signal to the second output component that performs display according to the progress of the game. Connected to the bus. For this reason, it is prevented that the output data is affected by noise or the like, thereby affecting the operation of the movable part according to the progress of the game.

Also, as shown in FIGS. 20 and 21, the third output circuit that outputs an output signal to the performance indicator among a plurality of output circuits connected by a common data bus is the progress of the game other than the performance indicator. Connected to the data bus so that the length of the wiring pattern to the game control microcomputer is shorter than the second output circuit that outputs an output signal to the display (second output component) that performs display according to ing. For this reason, it is difficult for the content modification of the performance display due to the placement of unauthorized parts or the like to be unauthorized.

Further, as shown in FIG. 21, the wiring pattern on the mounting surface connected through the through hole at the position Q in the figure from the wiring pattern constituting the data bus on the solder surface side outputs an output corresponding to the progress of the game. Connected to the terminal of the second output circuit that outputs an output signal to the second output component to be performed, branches on the mounting surface, and the branched wiring pattern outputs an output signal corresponding to the progress of the game to the external device Connected to an external output terminal for output. In this way, it is connected to the second output circuit in order to perform output according to the progress of the game on the mounting surface side using the wiring pattern of the mounting surface connected through the through hole from the data bus formed on the solder surface. The wiring pattern connected to the second output circuit and the external output terminal are branched to the wiring pattern connected to the external output terminal for outputting an output signal corresponding to the progress of the game and the game to the external device. Since there is no need to branch from the data bus formed on the mounting surface to the solder surface side in order to branch to each wiring pattern connected to the wiring pattern, the wiring pattern is simply formed.

Note that the wiring pattern on the mounting surface side connected through the through hole from the wiring pattern constituting the data bus on the solder side outputs an output signal to the second output component that outputs according to the progress of the game. 2 It is connected to the terminal of the output circuit, and also has a configuration in which the branched wiring pattern is connected to an output circuit for outputting an output signal corresponding to the progress of the game to an external device. Well, even with such a configuration, in order to perform the output according to the progress of the game on the mounting surface side using the wiring pattern of the mounting surface connected through the through hole from the data bus formed on the solder surface By branching the wiring pattern connected to the second output circuit and the wiring pattern connected to the output circuit for outputting the output signal according to the progress of the game to the external device, a plurality of There is no need to branch to solder side from the data bus which is formed on the mounting surface in order to branch to the respective wiring pattern connected to the output circuit, the wiring pattern is simplified form.

Of the input circuits, the second input circuit is not connected to the data bus, and input data is transmitted directly to the game control microcomputer without going through the data bus. FIG.
As shown in FIG. 2, the wiring pattern connected to the terminal of the game control microcomputer on the mounting surface is once connected to the wiring pattern on the solder side through the through hole at the position T in the figure, and again at the position U in the figure. It is connected to the wiring pattern on the mounting surface side through the through hole, and is connected 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 first input component having relatively low importance among the input components used for controlling the game is connected to the game control microcomputer via the data bus. On the other hand, the second input circuit for detecting the input of the input signal from the second input component having higher importance than the first input component is not connected to the data bus, but directly through the data bus. It is designed to be connected to the game control microcomputer, and the input data based on the input signal from the second input component is sent to the data bus through which the input data from other input circuits and the output data to the output circuit are transmitted. Since it is transmitted to the game control microcomputer without intervening, input data based on important input signals can affect the input data from other input circuits and output data to the output circuit. Without kicking, and thus transmitted to the game control microcomputer.
