[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information device, and more particularly to a portable information device such as a computer, an information device having a communication function, and a word processor for connecting various devices included in the information device. Regarding the wiring structure.

[0002]

2. Description of the Related Art Information devices such as computers, electronic devices having communication functions, and word processors have various functions, and various devices are mounted in the devices or external devices to realize those functions. There is a connector that connects to the device at. For example, a drive device such as a hard disk drive device (HDD) or a floppy disk drive device (FDD) is built in the information device,
Alternatively, the card can be connected via a connector, and cards for realizing various functions such as a modem card, a semiconductor memo card, and a LAN card can be connected via the connector.

As a card having these various functions, P
CMCIA cards are becoming popular. This PCMCI
The A card is a card configured according to a standard called PCMCIA, and three types of cards having different thicknesses, type I, type II, and type III, are set according to the application, for example, 3.3 mm and 5 mm. , And 10 mm in thickness. And these three types of PCMCI
A card slot is used as a connector for connecting an A card.

In general, when various devices are attached to information equipment, especially for portable information equipment, there is a demand for a structure that realizes thinning and miniaturization. With such a configuration, for example, in the case of the PCMCIA card, a P type I and a type II P are commonly used so that the card slots can be shared by three types of PCMCIA cards.
The CMCIA card corresponds to the same card connector, and the type III PCMCIA card corresponds to the structure in which two type I / type II card connectors are stacked.

Therefore, two type I or type II PCMCIA cards or one type I and type II PCMCIA card are provided by means of a card slot having a structure in which two type I / type II card connectors are stacked. Each of them or one type III PCMCIA card can be mounted, which makes the card connector common.

Therefore, in order to have such a configuration, the PCMCIA for mounting the PCMCIA card is installed.
It is necessary to have a laminated structure in which the connector has two layers.

Conventionally, the following structure is known as a structure in which the PCMCIA connector has a two-layer laminated structure.

(1) As shown in FIG. 9A, on both sides of the circuit board 5 which is a rigid board or a thin double-sided circuit board,
A configuration in which two PCMCIA connectors of a first card connector 31 and a second card connector 32 are attached so as to sandwich the circuit board.

(2) As shown in FIG. 9 (b), a PCMCIA connector previously laminated by two layers is
A configuration that attaches to one side of a circuit board.

[0010]

In a conventional wiring structure for information equipment, when a double-sided circuit board is used as a board on which a mounting member such as a PCMCIA connector is installed, the number of steps for soldering the mounting member to the double-sided circuit board is reduced. Is a two-step process, which requires time and cost for mounting,
Moreover, the area of the circuit board is taken up by the through holes, and the area required for wiring is insufficient. Therefore, a large circuit board is required to secure a sufficient wiring area.

When this double-sided circuit board is avoided and installed on a single-sided circuit board, the above-mentioned increase in the number of soldering steps can be reduced, but in order to stack, the mounting members are stacked beforehand. It is necessary to keep this in mind, which leads to an increase in new steps.

Further, in the case where the mounting members are stacked and mounted, when a thick circuit board composed of a rigid board such as a main board is used as the mounting substrate, the thickness of the mounting member and the circuit board will overlap. There is a problem in that the thickness of the portable information device may be hindered.

By using a thin flexible circuit board (FPC) in place of the thick circuit board, it is possible to reduce the size and thickness of the information device. There is a problem in the circuit board and a problem that the cost is high, and when the single-sided flexible circuit board is used, there is a problem in that the number of steps is increased.

Therefore, the present invention solves the above-mentioned problems of the prior art, and attaches various devices to information equipment,
A single-sided circuit board can be used as the circuit board to be attached, and it is an object of the present invention to provide a wiring structure of an information device that can be miniaturized even when stacking attachment members.
