In addition, since the ground terminal is provided so as to extend in the cartridge mounting direction from the other terminals, the ground terminal contacts first when the cartridge is mounted, matches the ground potential of the game machine body and the ground potential of the cartridge, and excessively increases the electronic element of the cartridge. Voltage can be prevented from being applied. Therefore, it is possible to reduce operation failure and failure of the electronic element.

Hereinafter, a preferred embodiment according to the present invention will be described with reference to the drawings. FIG. 1 shows terminal arrangements of a game cartridge IC board and a TV tuner IC board of a portable TV game machine.

The terminal shape of this IC substrate 1 is common to the IC substrate for game cartridges and the IC substrate for TV tuners, and each terminal is 45 terminals arranged in a staggered manner on one end of the IC substrate, I1, T3, T5 ... T4 whose parts are indicated by odd numbers
3. T2, T4, T6 ... T4 with even numbers on the upper side of the T45 terminal
2. T44 terminal. Staggered terminals T1, T2, T3 from left end ...
The terminals are T44 and T45, and the terminals of T17 and T41 protrude longer than the other terminals toward the edge of the IC substrate.

The game console itself is connected as a game cartridge IC board or a TV tuner IC board via a 45-pin connector.The same connector can be used to connect different types of IC boards. Only terminals are provided independently.

FIG. 2 shows an embodiment of an IC substrate 2 for a game cartridge. This arrangement pattern includes external connection terminals T1 to T45 from ROM and RAM terminals arranged on the IC substrate.
Up to the wiring lines do not cross each other.

As a result, when the arrangement order of the terminals for external connection is shown,
As shown in the figure, CMOS (complementary) is a type of ROM.
Moss) In the order of the terminals 6, the terminals such as the address signal and the data signal line are arranged without the substrate terminals T3 to T33, and the voltage terminal Vc
c skips one and returns to terminal T35 of the board and terminal T2
Are located in The reason why the power supply terminal Vcc is skipped by one to form the substrate terminal T35 is to surely prevent a short circuit with a signal line such as the terminal T3.

The substrate terminals T36 to T40 are provided as extension terminals for adding RAM other than the CMOS.

The substrate terminals T16, T17, T18 are grounds, which are determined based on the order of the terminals of the CMOS. And it has three terminals in order to ensure grounding. Further, the board terminal T41 is also grounded, and is a terminal for determining the type of software of the game cartridge using the board terminal T42.

In the case of the game cartridge shown in FIG. 3, the terminals T41 and 42 are in a conductive state, and the terminal T42 is also grounded. Further, in a game cartridge in which another type of game is stored, if the terminal T42 is connected to a power supply terminal, a potential is generated at the terminal T42. In this way, by setting the potential of the terminal T42 to H1 or LOW depending on the content of the game software of the mounted game cartridge, this potential is detected on the game machine main body side and the game content of the mounted cartridge is detected. Can be determined. Further, a terminal T43 is a terminal for determining whether or not the television tuner cartridge is mounted, and all the game cartridges are connected to a power supply. The discrimination between the TV tuner cartridge and the game cartridge will be described later in detail.

The shape of the board terminals T17 and T41, which are grounds, is longer toward the board edge than the shape of the other board terminals, and contacts the connector edge earlier than the other board terminals when inserted into the connector. Then, the ground in the IC substrate is connected to the ground of the video game machine main body, and the potentials of both are matched. As a result, when a cartridge is inserted or removed while the main body of the video game machine is turned on, for example, the potentials of both become different and a voltage higher than a predetermined value is applied to the electronic element and the electronic element does not operate normally. Prevent the phenomenon from happening.

Substrate terminals T1, T26, T27, T34, T36, T37, T38, T39, T
40, T44 and T45 are unused.

Further, the power supply Vcc includes substrate terminals T2 and T35, which are connected to each other. Also earth T16, T17, T18 and T
41 are connected to each other. These connections are realized with a minimum of through holes.

The IC substrate terminals for the TV tuner shown in FIG. 4 have a 34V receiving circuit power supply at the substrate terminal T1 and a 5V signal circuit power supply at the substrate terminal T2. A signal terminal for transferring an image to a liquid crystal display unit of the video game machine body by a serial signal is arranged. The board terminals T16, T17, T18 and T43 are grounded, and the shape of the board terminals of the board terminals T17 and T41 is longer toward the board edge than the shape of the other board terminals like the IC board of the game cartridge. . For this reason, the board terminals T17 and T41 contact the connector edge earlier than the other board terminals when inserted into the connector, and the ground in the IC board of the cartridge is quickly connected to the ground of the video game machine body. This prevents a malfunction when a cartridge is inserted or removed while the power of the main body of the video game machine is turned on.

The board terminal T43 is a terminal for performing switching determination between the game cartridge and the TV tuner cartridge. In the case of a TV tuner cartridge, this terminal is grounded.
As a result, when the tuner cartridge is mounted on the connector, a LOW signal is transmitted to the TV game machine.
When this LOW signal is received, the clock is stopped on the video game machine side, and the operation of the CPU is stopped. That is, the functions of the computer on the TV game machine main body side are stopped, and only the functions necessary for the operation of the liquid crystal display panel, the power supply for the backlight, and the audio amplifier are operated.

Terminals T44 and T45 as sound terminals for TV tuners
Is used. In this way, the extension terminal is
By placing it after T35, the number of through holes is minimized.

An audio signal of a television broadcast, which is an analog signal, flows through a line connected to the sound terminal. On the other hand, as described above, the digital signal for driving the liquid crystal of the display section flows through the line connected to the substrate terminals T5 to T31. In order to prevent the digital signal from interfering with the analog signal, the board terminals are arranged so that the line for the video display signal and the line for the sound signal are separated as shown in FIG. Furthermore, a terminal T5 for a video display signal
A ground terminal T43 is arranged between the sound signal terminals T44 and 45 and the sound signal terminals T44 and 45, and this ground line prevents the video display signal from being mixed into the sound signal line.

Further, two power supplies are arranged from the board terminals T1 and T2 on the opposite side, which are separated from the sound terminals T44 and T45.

This maintains the distance and reduces the effect of the analog waveform from the sound signal on the DC power supply, thereby minimizing the penetration of the pulsating waveform of the DC power supply and reducing the influence on each element of the TV tuner. ing.

As described above, according to the present embodiment, the use terminals of the IC substrate of the frequently used game cartridge are arranged avoiding the end of the cartridge, so that the user does not touch the cartridge when inserting or removing the cartridge. I can do it. Also, C
Since the substrate terminals are arranged in the order of the MOS terminals, a jumper called a through hole can be set to a minimum.

In addition, a part of the ground terminal extends in the cartridge insertion direction from the other substrate terminals, and the ground terminal contacts first when the cartridge is mounted. As a result, even if the cartridge is inserted or removed while the power is turned on, malfunction of an electronic element such as a CMOS disposed in the cartridge is prevented.

In addition, by disposing the power supply terminal and the signal terminal apart from each other, it is possible to prevent the electronic element from being broken due to a short circuit.

In addition, by disposing the ground terminal away from the power terminal, it is possible to prevent the terminal from being mistaken for the power terminal.

Further, regarding the terminal arrangement of the TV tuner cartridge, the power supply terminal and the ground terminal which can be used in common with the game cartridge are used as they are, and a part thereof is arranged so as to be the power supply terminal or the ground terminal depending on the type of the cartridge. I have. That is, when a certain terminal is equipped with a game cartridge, the terminal is connected to a power source and has a high potential, and when a tuner cartridge is mounted, the terminal has a low potential. The type of the cartridge that has been set can be determined.

Further, a terminal for a sound signal from the TV tuner is arranged at an end of the cartridge, and a power supply terminal is arranged at the other end. As a result, the sound signal is not mixed into the power supply line and becomes a pulsating waveform so as not to affect each element of the television tuner.

Further, a terminal of a signal for driving a liquid crystal of a display unit, which is a digital signal, and a terminal of the sound signal, which is an analog signal, are arranged apart from each other. This prevents the video display signal from being mixed into the sound signal line.

Therefore, by simplifying the terminal arrangement of the game cartridge substrate having a large number of manufactured parts, the number of manufacturing steps can be reduced, and further consideration is given to enhancing safety.
It becomes the selected product. Also, by matching the terminal arrangement of the TV tuner to the terminal of the game cartridge, two external parts that are not used simultaneously can be connected with the same connector, and the connector can be shared and used. The number of parts can be greatly reduced.

(Effects of the Invention) As described above, according to the present invention, by arranging the power supply terminal or the power supply terminal between the sound signal terminal and the video display signal terminal, noise leaking from the video display signal line is obtained. Can be cut off by the power supply line, and this can be prevented from being mixed into the sound signal line.

In addition, since the ground terminal is provided so as to extend in the cartridge mounting direction from the other terminals, the ground terminal contacts first when the cartridge is mounted, matches the ground potential of the game machine body and the ground potential of the cartridge, and excessively increases the electronic element of the cartridge. Voltage can be prevented from being applied. Therefore, malfunctions and failures of electronic elements can be reduced.
