Portable information processing apparatus having multiple rotatable port covers

A portable information processing apparatus comprising:

• a flat box-like housing including an upper surface, a bottom surface, side surfaces continuous with the upper and bottom surfaces, and a plurality of storage portions which are defined in the housing and have insertion ports open to one of the side surfaces, respectively, for storing optional components;
• a first cover provided on said one side surface of the housing to be rotatable between a closed position, wherein the insertion port of one of said plurality of storage portions is closed by the first cover, and an opened position wherein the insertion port of said one storage portion is open;
• and
• a second cover provided on the housing to be rotatable between a closed position, wherein the first cover located in the closed position and the insertion port of another storage portion are covered with the second cover, and an opened position wherein the first cover and the insertion port of said another storage portion are exposed;
• the first and second covers having rotational center axes which are substantially parallel to each other.

A portable information processing apparatus comprising:

• a housing storing electronic components, the housing including a first storage portion for storing a first card-like electronic component, and a second storage portion for storing a second card-like electronic component having a connecting terminal connectable to a cable, the first and second storage portions having insertion ports open to one side surface of said housing, respectively;
• a first cover provided on the housing to be rotatable between a closed position, wherein the insertion port of the first storage portion is closed by the first cover, and an opened position wherein the insertion port of the first storage portion is open;
• a second cover provided on the housing to be rotatable between a closed position, wherein the first cover located in the closed position and the insertion port of the second storage portion are covered with the second cover, and an opened position wherein the first cover and the insertion port of the second storage portion are exposed, the second cover having a through port opposing the insertion port of the second storage portion;
• and
• a third cover provided on the second cover to be rotatable between a closed position, wherein the through port is closed, and an opened position wherein the through port is open so as to allow a cable to pass the through port.
