<p><P>PROBLEM TO BE SOLVED: To provide a mobile terminal device which has two cases coupled to each other in a mutually rotatable state, where the two cases are capable of being held in a mutually closed state. <P>SOLUTION: The mobile terminal device 1 comprises the two cases 2 and 3, which can be put one over the other along the thickness and a coupling means of enabling the two cases 2 and 3 to rotate about a first reference axis extending along the thickness and also coupling the case 2 to the case 3 so that the case 2 can oscillate about a second reference axis orthogonal to the first reference axis, with the mobile terminal device 1 being such that a recessed portion 10 is provided on an opposite surface 2a of the case 2 in a closed state, wherein the two cases 2 and 3 are put one over the other and a projection portion 15 to be inserted into the recessed portion 10 is provided on an opposite surface 3d of the case 3. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
