2. Description of the Related Art In recent years, with the spread of portable personal computers such as notebook computers, portable personal computers are now being used by businessmen when they participate in meetings, meetings, conferences, lectures, etc. on business trips. It has become an indispensable tool as a portable information device. Therefore, naturally, a portable personal computer which is excellent in portability, such as small, thin, and lightweight, has naturally been required. However, due to recent technological advances such as the Internet and image communication, high functionality of portable personal computers is required, and the portable personal computers are becoming smaller, thinner and lighter than the original portable personal computers. In particular, regarding the thin type,
Central processing unit (CPU) which is the central part of computer
IC maker, which is a supplier of
It has been supplied and sold as a daughter card in which peripheral components are mounted on a CPU. The daughter card is thicker and larger (for example, approximately 10 × 6)
At present, it is difficult to design a portable personal computer to be thinner.

FIG. 8 is a plan view showing a state in which a cover of a general portable personal computer is opened, and FIG. 9 is a partially cutaway plan view showing an arrangement structure of members of a main body of a conventional portable personal computer. 10 is a sectional view taken along line AA of FIG. 9, and FIG. 11 is a sectional view taken along line BB of FIG.

Is arranged. The battery 17 fits within the thickness of the battery pack 18, H = about 23 mm, for example, by arranging a plurality of lithium ion batteries having a diameter of about 18 mm. Therefore,
It is possible to make the thickness H of the battery pack 18 equal to or less than the total thickness of the portable personal computer 1, G = about 25.4 mm.

[0035]

As described above, according to the portable personal computer of the present invention, the IC maker that supplies the CPU supplies the CPU as a CPU daughter card having peripheral components mounted on the CPU instead of the CPU alone. Therefore, a portable personal computer having a total thickness of 1 inch could not be constructed with the conventional arrangement structure. The first area with the keyboard on the body has a thin H
In the second area where the DD is arranged and no keyboard is provided,
By arranging the CPU daughter card and the two-stage PCMCIA slot, it has become possible to achieve the total thickness of the portable personal computer of 1 inch.

In the first area, one-stage PCMCI
Two A-slots are distributed and the second area has a CPU
By distributing the daughter card and the HDD, the total thickness of the portable personal computer can reach 1 inch.

Further, by arranging the battery pack so as to protrude outside the main body, the thickness of the battery pack could be absorbed below the thickness of the laminated portion of the main body and the lid.

As described above, the PC from the IC maker
According to the supply of the U daughter card, by arranging each member to be housed in the main body in an optimal arrangement structure, the total thickness, which was difficult with the conventional arrangement structure, can be attained to the required 1 inch, and it is thin. Portable personal computer can be easily provided.
