DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base board mounted on an electronic device such as a personal computer or a word processor, and to an electronic device mounted on the base board such as a personal computer or a word processor.

[0002]

2. Description of the Related Art FIG. 6 is a schematic plan view showing the structure of a conventional base board. FIG. 7 is a schematic perspective view showing a conventional electronic device on which a base board is mounted.
FIG. 8 is a plan view showing the inside of the electronic device viewed from the Y direction in FIG. In the figure, 101 is a base board, 102a is a first I / O slot mounted on the base board 101, and 102b is a second I / O slot mounted on the base board 101.

[0003] Also, 111 is a personal computer,
An electronic device such as a word processor, 112 is a housing, 11
Reference numeral 3 denotes a power storage unit in which power is stored, and 114 denotes a CD-ROM.
This is a front device storage unit in which a front device such as a ROM is stored.

Next, the operation will be described. When an extension board is mounted on the conventional base board 101, the first I / O
An expansion board for the first I / O slot 102a is connected to the O slot 102a, and the second I / O slot 102b
Is connected to an expansion board for the second I / O slot 102b.

[0005]

Since the conventional base board is configured as described above, the types of I / O slots mounted on the base board are fixed, and different types of I / O slots are used. There is a problem that the expansion board for the computer cannot be installed. For example, in the case shown in FIG.
An expansion board for the first I / O slot 102a and a second
Only the expansion board for the I / O slot 102b can be installed.

The I / O mounted on the base board
There is a problem that the number of O-slots is fixed for each type of I / O slot, and the number of expansion boards mounted is limited for each type of I / O slot. For example, in the case shown in FIG. 8, only two expansion boards for the first I / O slot 102a and three expansion boards for the second I / O slot 102b can be mounted.

The I / O mounted on the base board
There is a problem that the position of the O slot is fixed, and the mounting position of the expansion board is limited. For example, in the case shown in FIG. 8, the extension for the first I / O slot 102a
The mounting position of the board is either the first or second from the top, and the mounting position of the expansion board for the second I / O slot 102b is any of the third to fifth from the top. .

Further, when there is an obstacle overlapping the base board, the size of the expansion board to be mounted at the position of the base board overlapping the obstacle is limited. Is fixed for each type of I / O slot, the size of the expansion board for a specific type of I / O slot to be mounted at the position of the baseboard overlapping the obstacle is limited. There was a problem that. For example, in the case shown in FIG. 8, the base board 101 and the front device storage unit 114 overlap each other, and the overlap extends to the first I / O slot 102a located at the top and to a horizontal position. The first I / O slot 102a located at the top has an extension board for the narrow first I / O slot 102a.
Only de can not be installed.

Next, the operation will be described. Embodiment 1
When an expansion board is mounted on the base board 1 according to (1), first, a required number of I / O slots having I / O slots for the expansion board to be mounted are prepared. Then, the I / O slot sections are connected in a predetermined order to configure the expansion board section 3. Then, the base board 1 is configured by connecting the expansion board section 3 configured as described above to the main board section 2.

When the base board 1 is configured as described above, signals for all the I / O slot portions flow through the expansion board constituting each I / O slot portion, and each I / O slot portion is formed. A signal for each I / O slot portion flows through the I / O slot.

Specifically, three first I / O slots 4a and two second I / O slots 4b are prepared. The first to third from the top are the first I /
O slot 4a, the fourth and fifth from the top are the second I
The expansion board unit 3 is configured by connecting the first and second I / O slot units 4a and 4b so as to form the I / O slot 4b. Then, the extension board 3 configured as described above is connected to the main board 2 to form the base board 1. I / O
The connection between the slot portions is performed by using one female connector portion 21.
The connector connection is performed by inserting the other male connector portion 22 into the connector. The main board 2 and the extension board 3 are connected to the female connector (not shown) provided on the main board 2 by connecting the male connector 22 of the first I / O slot from the top. The connection is made by inserting a connector.

When the base board 1 is configured as described above, as shown in FIGS. 5A and 5B, the first I / O
The first wiring 23a passes through the first wiring 23a by the first wiring 23a on the first expansion substrate 5a forming the slot 4a and the second expansion substrate 5b forming the second I / O slot 4b. A signal for the first I / O slot section 4a flows, and a signal for the second I / O slot section 4b flows through the second wiring 23b through the second wiring 23b. And the first
A signal for the first I / O slot 4a flows through the first I / O slot wiring 24a through the first I / O slot 6a constituting the I / O slot 4a. A signal for the second I / O slot portion 4b flows through the second I / O slot 6b constituting the second I / O slot portion 4b through the second I / O slot wiring 24b.

Thereafter, an expansion board for the first I / O slot 6a is connected to the first I / O slot 6a provided in the first I / O slot section 4a, and the second I / O slot An expansion board for the second I / O slot 6b is connected to 6b.

As described above, according to the first embodiment, the base board 1 is configured to include the main board section 2 and the extension board section 3, and the extension board section 3 is provided with a plurality of I / Os. Slots are provided, each I / O slot is provided with an extension board and an I / O slot mounted on the extension board, and signals for all I / O slots flow through the extension board. A signal for each I / O slot is configured to flow through the I / O slot, the main board 2 and the extension board 3 are connected to each other with a connector, and adjacent I / O slots are connected to each other. Because it was configured to connect to the connector, I /
The effect that the type of O slot, the number of each type of I / O slot, and the position of the I / O slot can be freely changed is obtained.

If the position of the I / O slot is fixed for each type of I / O slot, a specific type of I / O slot to be mounted at the position of the base board overlapping the obstacle is provided. The conventional problem that the size of the expansion board is limited can be solved by arranging the I / O slot in which the wide expansion board needs to be mounted at a position not restricted by an obstacle.

In the first embodiment, the extension board 3
Is described with five I / O slots, but the same effect can be obtained even when the extension board 3 is composed of five or more I / O slots. Can be.
