Patent ID: 8582293

Claim:
A portable electronic apparatus comprising: a first casing having a display surface in its surface; a second casing having a display surface in its surface; a coupling mechanism adapted to couple the first casing and the second casing to each other to take at least two states which are a closed state where the display surface in the first casing is covered with a rear surface of the second casing and also the display surface in the second casing is exposed, and an open state where the second casing has been moved with respect to the first casing from the closed state, and the display surfaces in both the casings are exposed in the same plane; and a sliding mechanism adapted to slide the second casing with respect to the first casing within the same plane in the open state; wherein the coupling mechanism includes an abutting surface at a position which comes into contact with the second casing in the closed state, and the sliding mechanism includes an abutting receiving surface at a position which is in contact with the abutting surface in the coupling mechanism in the closed state and is out of contact with the abutting surface in the open state.
