This is a divisional of application Ser. No. 10/310,007, filed Dec. 4, 2002 now U.S. Pat. No. 6,944,030.
BACKGROUND OF THE INVENTION This application claims the benefit of a Japanese Patent Application No. 2002-112247 filed Apr. 15, 2002, in the Japanese Patent Office, the disclosure of which is hereby incorporated by reference.
The printed wiring on the substrate may be provided on both top and bottom surfaces of the substrate but the printed wiring must be arranged avoiding positions where the various parts are mounted on the substrate and positions where holes and cutouts are formed in the substrate. Signals supplied to the display section employ the LVDS system or the like, and are high-speed and small-amplitude signals. Hence, the substrate must satisfy various layout and wiring conditions, such as limited wiring length and wiring layout for preventing mixture of external noise. Accordingly, depending on the layout and wiring conditions, it is necessary to take measures such as arranging the IC chip for driving the display section in a vicinity of the connecting part on the substrate, and arranging the printed wiring on the substrate at a position separated from other printed wiring for the high-speed signals.
Still another object of the present invention is to provide a substrate comprising an electrical wiring pattern formed on the substrate; one or a plurality of electrical parts provided on the substrates; a first contacting part and a second contacting part provided on the substrate and electrically connected to the electronic parts; and one or a plurality of electrical connecting bodies, different from the electrical wiring pattern, electrically connecting the first contacting part and the second contacting part. According to the substrate of the present invention, it is possible to conform to the various restrictions with respect to the printed wiring on the substrate, secure a relatively large degree of freedom of wiring, and electrically connect a portion on the substrate and another portion, while simultaneously meeting the demands to reduce both the cost and size of the electronic equipment.
A further object of the present invention is to provide an electronic equipment comprising a main body internally having a substrate and a first electrical connecting body, the first electrical connecting body having a first contacting part electrically connected to one or more electronic parts provided on a first surface of the substrate and a second contacting part; a lid which opens and closes with respect to the main body; a second electrical connecting body electrically connecting the lid and the substrate, the second electrical connecting body having a first contacting part electrically connected to the lid and a second contacting part; and a connecting part, provided on the substrate, electrically connecting the second contacting part of the first electrical connecting body and the second contacting part of the second electrical connecting body at a height position separated by a predetermined distance from the first surface of the substrate. According to the electronic equipment of the present invention, it is possible to conform to the various restrictions with respect to the printed wiring on the substrate secure a relatively large degree of freedom of wiring, and electrically connect a portion on the substrate and another portion, while simultaneously meeting the demands to reduce both the cost and size of the electronic equipment.
A frame 18 and a main board (hereinafter simply referred to as a substrate) 19 which is fixed to the frame 18, are provided within the main body 10. Various electronic parts such as an IC chip, and various parts such as a heat sink 20 are provided on the substrate 19. The electronic parts such as the IC chip are electrically connected via a printed wiring (electrical wiring pattern) on the substrate 19 and a FPC 21. As will be described later, the electrical connection between the display section 11A and the substrate 19 is made using a FPC 22. One end of the FPC 22 is connected to the display section 11A, and the other end of the FPC 22 is connected to a first connecting part 23 which is provided on a top surface of the substrate 19. The first connecting part 23 electrically connects the other end of the FPC and one end of the FPC 21. As will be described later, the other end of the FPC 22 is electrically connected to the electronic parts such as the IC chip on the substrate 19 via another connecting part and the printed wiring on the substrate 19.
In this embodiment, the first connecting part 23 and the second connecting part 43 are provided at positions mutually deviated in the horizontal direction in FIG. 2. Thus, the FPC 21 has a curved shape at an intermediate portion thereof as indicated by a dotted line in FIG. 2. However, the FPC 21 may of course have a shape which extends linearly. In addition, although the FPC 21 is bent from the top surface side to the bottom surface side of the substrate 19, the FPC 21 may exist only on the top or bottom surface of the substrate 19.
Next, a description will be given of the conditions for not increasing the thickness of the lap-top personal computer even when the FPC is used, by referring to FIG. 5. FIG. 5 is a diagram for explaining the positional relationships of the heights of the parts on the substrate 19 and a FPC 21-1. In FIG. 5, it is assumed for the sake of convenience that the FPC 21-1 has a shape which extends linearly, and that parts 51 through 54 respectively having heights h1 through h4 are provided on the substrate 19, where h1>h4>h3>h2. The height h4 of the part 54 is the highest, and determines the thickness of the lap-top personal computer) W1 denotes a distance between the parts 51 and 54, and W2 denotes a width of the FPC 21-1.
In the embodiment of the electronic equipment described above, two FPCs 21 and 22 are provided with respect to the substrate 19. However, the electrical connecting bodies are not limited to the FPC, and a wire harness may be used, for example. In other words, the electrical connecting body may be formed by various means other than the printed wiring (electrical wiring pattern) formed on the substrate, 19. In addition, the electrical connecting bodies such as the FPCs 21 and 22 simply need to electrically connect one portion on the substrate 19 and another portion, and one or three or more electrical connecting bodies may be used. In this case, the other portion to be connected to the one portion on the substrate 19 by the one or more electrical connecting bodies may be located on the substrate 19 or located outside the substrate 19.
The application of the present invention is of course not limited to the lap-top personal computer, and the present invention is similarly applicable to various electronic equipments such as information processing apparatuses and portable telephones which are made up of a main body and a lied which opens and closes with respect to the main body.
