Abstract
Abstract In a portable computer, with a body section having a keyboard with a plurality of keys, and a cover section having a display unit, rotatably coupled by a pair of hinge portions, the hinge portions are provided at opposite sides of the cover section and coupled with the rear end of the body section. A battery enclosing portion of the body section is provided between the hinge portions. With this construction, the battery enclosing portion does not obstruct a reduction in depth of the whole apparatus, so that a dimension of the display unit can be increased in comparison to conventional ones, and the display unit can be easily seen.
