Abstract

A display element, a holder and a substrate are stacked and housed in between a front case and a back case of a receiving section of a mobile terminal device. The front case has a rib, and the rib has a plurality of recesses shaped near four cases of the housed display element to reduce the rigidity against an impact.

Claims

1. A mobile terminal device comprising:

a transmitting section; and

a receiving section,

wherein the receiving section has a front case and a back case that are put together, a display element, a holder and a substrate which are housed in between the front case and the back case, the front case of said receiving section has a rib larger than a circumference of said display element, and the rib has a plurality of recesses along the circumference thereof to reduce a rigidity against an impact.

2. The mobile terminal device according to claim 1, wherein at least some of said plurality of recesses are shaped near corners of said display element.

3. The mobile terminal device according to claim 1, wherein four recesses are shaped near four corners of said display element.

4. The mobile terminal device according to claim 1, wherein said transmitting section and said receiving section are capable of mutually rotating about a hinge.

5. A mobile terminal device having a display element mounted thereon and a case that houses said display element and has a plurality of recesses along a circumference thereof.

6. The mobile terminal device according to claim 5, wherein said plurality of recesses are shaped at four corners of said case.

7. The mobile terminal device according to claim 5, wherein said case is mutually rotatably connected to another case by a hinge.
