ABSTRACT:
A portable information terminal includes a first casing having a manipulation unit at its surface, a second casing having a display unit at its surface, and a rotation link mechanism linking the first casing and the second casing such that the second casing rotates slidably with respect to the first casing. The rotation link mechanism is configured to allow transition, by one rotating operation, from one to another of a closed state in which the second casing entirely covers the manipulation unit of the first casing and an open state in which the manipulation unit of the first casing is exposed as a result of movement of the second casing that takes an axially symmetric orientation to the center line of the first casing in the open state. Thus, the operation from a closed state up to an open state can all be readily conducted with one hand.
