DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic toy such as a video game machine or a television educational device in which a predetermined image is displayed on an image display device (display) and an operator performs a desired operation while watching the image. The present invention relates to an IC memory cartridge in which software contents are stored.

[0002]

2. Description of the Related Art A predetermined image is displayed on a display,
An electronic toy in which an operator performs a desired operation while viewing this image has been developed. For example, a so-called video game machine corresponds to this. In addition, a television educational device has been developed for young children and children, in which learning software for learning and calculating picture books and characters is displayed on a display, and learning can be performed as if a video game. Hereinafter, an electronic toy including such a television educational device will be described.

In these electronic toys, a cartridge in which predetermined software contents are stored is mounted on a connector portion of an operating device main body, and the operation of the software contents is performed. , Various software can be used.

The cartridge is provided with an IC memory for storing game contents and educational software. The IC memory is mounted on an IC substrate, and a wiring pattern made of copper foil is provided on the IC substrate in order to connect each terminal of the IC memory to a terminal of the connector.

[0005]

Since the wiring of the IC substrate as described above cannot intersect in one plane, wiring is also performed on the back surface of the substrate, and the wiring on the front and back is connected using through holes. This has dealt with the wiring pattern that has to cross.

However, laying the wiring patterns on both the front and back surfaces of the IC substrate has a problem that the number of steps and the cost are increased.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has as its object to provide an electronic toy cartridge capable of reducing the number of steps for laying a wiring pattern on an IC substrate. .

[0008]

In order to achieve the above object, an IC memory cartridge for an electronic toy according to the present invention comprises: an IC memory for storing software contents; and the IC memory. And an IC board on which signal copper foil wiring is provided on only one side for sending information stored in the operating device body.

[0009]

The present invention has the above-described configuration, and has an IC
The wiring pattern needs to be laid only on one side of the substrate, and the number of work steps can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments according to the present invention will be described below with reference to the drawings. FIG. 1 shows a terminal arrangement of an IC substrate for a game cartridge of a portable television game machine. This terminal is connected to a terminal provided on a connector section of the game machine main body, so that the game content stored in the IC memory can be read out by the game machine main body.

Each terminal of the IC substrate 1 is arranged in a staggered manner on one end of the IC substrate, and 45 terminals are provided. T1, T3, T5... T4 in which the lower end of the substrate is indicated by odd numbers
3, T2, T45 terminals whose upper side is indicated by an even number
4, T6 ... T42, T44 terminals. The terminals T1, T2, T3... T44, T45 are arranged in a staggered manner from the left end, and the terminals T17 and T41 protrude longer than the other terminals toward the edge of the IC substrate.

The main body of the video game machine is connected to the IC memory of the game cartridge by connecting the 45-pin connector terminal and the aforementioned IC substrate terminals T1 to T45.

FIG. 2 shows an embodiment of an IC substrate 2 for a game cartridge. This wiring pattern
Wiring lines 4a, 4b, from terminals of ROM or RAM arranged on the IC substrate to terminals T1 to T45 for external connection.
4c, the signal wiring lines 4a have a pattern such that they do not cross each other on only one side of the IC substrate.

As a result, when the arrangement order of the terminals for external connection is shown, as shown in FIG. 3, the terminal order of a CMOS (complementary MOS) 6 which is a kind of IC memory (ROM) is as follows.
Terminals such as an address signal and a data signal line are arranged from the substrate terminals T3 to T33, and the voltage terminal Vcc is disposed at the substrate terminal T35 and back to the terminal T2, skipping one. One power supply terminal Vcc is skipped and the substrate terminal T3
The reason for setting to 5 is to surely prevent a short circuit with a signal line such as the terminal T3.

The substrate terminals T36 to T40 are C
It is provided as an extension terminal for adding a RAM other than the MOS6. In the IC board 2 of the present embodiment, a capacitor (not shown) is mounted on the copper foil pattern 5 on the board.

The substrate terminals T16, T17 and T18 are grounds, which are determined based on the terminal order of the CMOS 6. And it has three terminals in order to ensure grounding. Further, the substrate terminal T41 is also grounded, and is a terminal for determining the type of software of the game cartridge using the substrate terminal T42.

As described above, since the terminal arrangement of the CMOS 6 is developed and the terminal arrangement of the IC substrate is determined according to the arrangement order, it is sufficient to lay the wiring lines 4a, 4b, and 4c only on one side. In this embodiment, the signal wiring line 4a for exchanging signals between the CMOS 6 and the game machine main body is wired only on one side of the IC substrate. The power supply lines 4b are connected to the copper foil pattern on the back surface through the through holes 3, and a plurality of power supply lines 4b are connected to eliminate the potential difference between the lines. Also, a plurality of lines are similarly connected to each other for the earth line 4c so that the earth potential is constant. As described above, a stable voltage can be supplied by connecting each of the plurality of power lines and the plurality of ground lines 4c.

In this embodiment, the substrate terminals T1, T2
6, T27, T34, T36, T37, T38, T3
9, T40, T44 and T45 are unused.

As described above, the frequently used terminals are disposed inside the end portion which is easy to touch by hand when inserting or removing the cartridge, thereby preventing malfunction and preventing the terminals from being rusted. Further, since the terminals of the substrate are arranged in the order of the terminals of the CMOS 6, signal lines are connected to ICs.
It can be arranged on only one side of the substrate.

Therefore, by arranging the terminals of the game cartridge substrate, which is manufactured in a large number, most easily, the number of manufacturing steps can be reduced, and further consideration is given to enhancing the safety.

[0021]

As described above, according to the present invention, it is sufficient to lay the signal wiring pattern only on one side of the IC substrate, and the number of manufacturing operations can be reduced. Therefore, the cost can be reduced, and the cartridge for the electronic toy can be provided at low cost.
