Patent ID: 7058435

Claim:
A portable terminal device comprising: a case section formed into the shape of a plate; a connector section that opens to the outside from a lateral surface of the case section along the direction of thickness and electrically connects with another terminal device; a connector cap formed from an elastic body that opens and closes an opening of the case section; and a holding unit that maintains the opening in a closed state, wherein the connector cap is provided with a first wall section that protrudes roughly perpendicularly to the lateral surface from a peripheral edge of the opening located on one end of the case section in the direction of thickness, and a second wall section that protrudes from the other end of the case section in the direction of thickness and is continuous with the first wall section, the second wall section is coupled to the other end of the case section in the direction of thickness to swing freely, and in a state in which the opening is closed, the first wall section being exposed on a top surface of the case section substantially perpendicularly to the direction of thickness of the case section, with a distal end section of the first wall section located farther away from the opening relative to a coupling section between the second wall section and the case section.
