  In recent years, the performance of a camera provided in a mobile phone has been rapidly improved, and a camera having an additional function such as an optical zoom function has been developed. For this reason, the size of the camera part is also increasing with the improvement of such performance. However, in the mobile phone 101 shown in FIG. 11, the casing 107 in which the hinge device is accommodated is positioned between the hinge support portion 104m and the hinge support portion 104n. Cannot be used as a space for accommodating the camera unit. For this reason, a space for accommodating the camera unit is secured in the housing 103 by forming a surface 153 that is raised by one step from the surface 103 b in the housing 103.

  However, since mobile phones are carried around in everyday life, the demand for miniaturization is stronger than ordinary products. For this reason, when the surface 153 is formed on the housing 103, the thickness of the mobile phone 101 increases, and there arises a problem that such a request cannot be sufficiently satisfied.

  Accordingly, an object of the present invention is to solve the above-described problem and to provide a portable device that is sufficiently downsized.

  A portable device according to one aspect of the present invention includes a base portion having a main surface, and a protrusion that is located at the periphery of the main surface and protrudes from the main surface, and communicates between the base portion and the protrusion. A first housing that defines the internal space, an electronic device that is positioned in the internal space and is accommodated in the first housing, and a protrusion that is pivotable about the first axis. And a second casing that is opened and closed with respect to the first casing.

  According to the portable device configured as described above, the electronic device is accommodated in the internal space that communicates from the base portion to the protruding portion connected to the second housing. For this reason, compared with the case where a protrusion part is not utilized as the space which accommodates an electronic device, the thickness of a base part can be made small and an electronic device can be accommodated. Thereby, size reduction of a portable apparatus can be achieved.

  Preferably, the protrusion has a pair of side surfaces that are spaced from each other in the direction in which the first axis extends. The second housing is provided with a U-shaped connecting member having a center portion, both ends branched from the center portion and connected to each of the pair of side surfaces, and a first display portion. And a movable member connected to the central portion so as to be rotatable about a second axis orthogonal to the first axis.
