1. Field of the Invention
The present invention relates to a portable computer which can be easily carried and brought.
2. Description of the Related Art
A conventional portable computer is provided with a hinge portion at the front side spaced from the rear end of the body section by a certain distance (for example, U.S. Pat. No. 4,571,456). This is because a battery chamber and a modem enclosing portion are provided at the rear side of the hinge portion. Consequently a problem exists in that the dimensions of a cover section are limited and the dimensions of a display unit installed in the cover section can not be made large.
Also in a conventional portable computer, since a battery chamber and a modem enclosing portion are provided at the rear side of the hinge portion, these members limit the rotational angle of the cover section in an open state, relative to the body section, to about 135 degrees. The angle of 135 degrees does not produce a problem when the body section is used on a desk. However, if the computer has a liquid crystal display unit the body section is put and on a person's knee during the person's use outdoors or during use in a vehicle, the person's eyes are not orthogonal to the display unit and viewing of the display content becomes difficult.
In fact, from the viewpoint of human engineering, it is preferable that the open angle of the cover section is about 155 degrees, at least when the computer is to be placed for use on the user's knee. Consequently, a conventional portable computer is limited substantially to use on a desk rather than use on a knee.
