Abstract
A device holder is placed on the lower region of a display unit, and part of an operating unit is placed on the holder. The operating unit is overlapping the display unit. Moreover, operating buttons other than those mounted on the holder are shaped so that the portions thereof projecting from a housing will have a substantially triangular cross section. Consequently, a finger with which the operating buttons are manipulated touches the portion of each of the operating buttons corresponding to the apex of the triangular cross section, that is, touches each of the operating buttons along a line. A degree to which the operating buttons are incorrectly manipulated is decreased, and the maneuverability of the operating buttons is held satisfactory. Moreover, the space between adjoining operating buttons is narrowed. Consequently, a portable cellular phone is greatly downsized to an extent equivalent to both a degree to which the operating unit is overlapping the display unit and a degree to which the space between adjoining operating buttons is narrowed.
