Figure 4 shows a side view of the back of the shape of the housing 4 of the portable terminal device of the embodiment. The housing 4 is formed are formed of a material containing carbon, such as carbon fiber-reinforced carbon composite material, or by the carbon composite is a carbon fiber laminate. By using these materials, it is possible to obtain thin, highly rigid, the effect of improvement of heat dissipation through thermal diffusion.

Incidentally, the housing 4 may be formed of a resin material such as fiber-reinforced resin containing glass fiber or the like, it is possible to ensure the rigidity with weight reduction. The housing 4 is of stainless steel, may be formed of a metal material such as aluminum, it is possible to enhance the rigidity. The housing 4 may be formed by a fiber-reinforced metal, only a portion of the housing 4 may be formed by a fiber-reinforced material.

As shown in FIG. 3, the center portion of the front face 4 of the housing 4, the opening 5 is provided with the display panel 3 are arranged. The housing 4, the outer edge portion near the both sides between the display panel 3 functions as a storage unit 6 for holding the housing 4.

As shown in FIG. 4, the housing 4, on the back 4b opposed to the display panel 3, the position near the both ends of the outer edge of the housing 4 towards the center of the back 4b, a pair of arc-shaped bulged portion 7 It is provided. A pair of arc-shaped bulging portion 7 is formed integrally continuously across the central portion of the back 4b.

Arcuate bulging portion 7, a position near the both ends of the outer edge of the housing 4 towards the center of the back 4b, the top portion of the bulging shape is disposed. Therefore, when the back 4b side of the housing 4 placed on a desk, the top of the pair of arc-shaped bulged portion 7, so that the contact with the desk.

The housing 4 by being integrally formed a pair of arc-shaped bulging portion 7 is continuously, the housing 4 overall mechanical strength, the housing 4 overall elasticity is secured.

Further, on the rear surface 4a of the housing 4, and the arcuate recess 8 is formed in the central portion between the pair of the arc-shaped bulged portion 7, the arcuate recess 8 through the arc-shaped bulged portion 7 outer edge of the casing 4 one curved continuous until both ends are configured. Back 4b of the housing 4, by gradual arc bulging portion 7 is formed, familiar to the shape of the palm holding the housing 4, stability during use is secured.

Further, the back 4a of the housing 4, as shown in FIG. 2, as in the direction perpendicular to the direction in which the arc-shaped bulged portion 7 are arranged at both ends of the outer edge portion of the housing 4, contiguous to the center of the rear face 4a by being chamfered, the chamfered portion 9 is formed.

Inside the housing 4, as shown in FIG. 4, the main circuit board 11 and the battery 12 are disposed in parallel with the display panel 3. The main circuit board 11, SD card is disposed on one end side in the longitudinal direction of the rectangular display panel 3, the USB slot 14, SD memory card USB (Universal Serial Bus) memory 13 is insertion is insertion slots 16, filling the terminal 17, SIM (Subscriber Identity Module card) SIM card slot 19 card is inserted and removed, the camera unit 21 lens was arranged on the rear side of the housing 4, an earphone jack 22 or the like are mounted. The housing 4 has a cover for covering the various slots 14,16,19 and filling pin 17 (not shown), respectively.

As described above, mounting parts group having a thickness including relatively large camera unit 21 within the mounting part by being arranged gathered at one end of the housing 4, a thin thickness of the central portion of the housing 4 with achieving of a suitable thickness it is ensured as a holding part 6 for holding the housing 4.

Further, in the interior of the housing 4, on one end side in the longitudinal direction of the rectangular display panel 3, as shown in FIG. 4, a vibrator 24, a microphone 25, an antenna 26 is disposed. Antenna 26, along the outer edge of the housing 4, are extended in the longitudinal direction of the display panel 3.

When operating the display panel 3 at a portable terminal device 1 configured as described above on a desk, described stress acting on the back surface 4b of the housing 4. Figure 5 shows a schematic diagram for explaining a stress acting on the housing 4 during use of the portable terminal device 1 of the embodiment.

As shown in FIG. 5, the mobile terminal device 1 may when operating the display panel 3, is used in a state placed to the back 4b side of the housing 4 is in contact with the desk. In this case, the pressing force of such finger operating the display panel 3, thereby outwardly displacing (pressing) the entire casing 4 on the desk.

In the present embodiment, the pressing force applied to the housing 4 during the operation of the display panel 3 acts on the pair of the arc-shaped bulged portion 7. Therefore, according to the housing 4 having a pair of arcuate protruding portion 7, for example, as compared with the shape of acute-angled corner on the back of the casing is formed, a portion where the stress is concentrated on the back 4b avoid to occur, it is possible to prevent damage of the housing 4 and the display panel 3.

As described above, according to the mobile terminal device 1 of the embodiment, the back 4b of the housing 4 by a pair of arc-shaped bulging portion 7 is continuously formed, thin efforts were made housing 4 prevent deterioration of the mechanical strength of, it is possible to prevent damage of the housing 4 and the display panel 3.

Further, according to the mobile terminal device 1 of the embodiment, it is possible to improve the have ease of use. In addition, for example, in a state that the user sitting, by placing the arcuate recess 8 of the back 4b to overlie the foot of the thigh, it is also possible to support the auxiliary rear 4b of the housing 4 feet. Thereby, it is possible to secure the stability during the operation of the display panel 3, to improve the handling properties of the portable terminal device 1.

Further, the back 4b of the housing 4, a position near the both ends of the outer edge toward the center of the back 4b, by a pair of arc-shaped bulging portion 7 is provided, and the outer edge portion of the housing 4, and the desk gap is secured between. Thus, when lifting the portable terminal device 1 placed on a desk, it is possible to easily grip the outer edge of the housing 4 the portable terminal device 1 placed on a desk with a fingertip. As a result, it is easy to lift the housing 3 from the desk, it is possible to improve the handling properties of the portable terminal device 1.

Similarly, the back 4b of the housing 4, in a direction orthogonal to the direction in which the pair of arc-shaped bulging portion 7 is arranged, by the chamfered portion 9 is formed at both ends of the outer edge of the housing 4, the housing 4 and the outer edge portion of a gap is secured between the desk. Thus, when lifting the portable terminal device 1 placed on a desk, the housing 4 the mobile terminal device 1 placed on a desk, easily grasped by fingertips on both sides of the outer edge portion in the short side direction of the display panel 3 it becomes possible. As a result, it is easy to lift the housing 3 from the desk, it is possible to improve the handling properties of the portable terminal device 1.

In the case of using the mobile terminal device 1 on a desk, the space between the pair of the arc-shaped bulged portion 7, since the function as a conductive path for air, excellent in heat dissipation.

The electronic device according to the present invention is not limited to a tablet PC as an information terminal device 1 of the embodiment, for example, PDA (Personal Data Assistant), a cellular phone including a smart phone, an electronic book terminal, a portable game machine is suitable used for like.

Although the invention has been described with reference to the embodiments, the present invention is not limited to the above embodiment. Structures and details of the present invention can be various modifications that those skilled in the art can understand within the scope of the present invention.

This application claims priority based on Japanese Patent Application No. 2011-167290, filed on July 29, 2011, the entire disclosure of which is incorporated herein.
