A portable information equipment has a main body portion and a display portion hinged each other. A space is secured in the display portion by using a cabinet for a reflection type liquid crystal display which requires no backlight instead of a liquid crystal display with backlight. The space is used for an additional internal battery. The additional internal battery increases an electric capacity to extend an operation time of the portable information equipment and need no externally attached extension battery.
