Description:
[0001]    The entire disclosure of Japanese Patent Application No. 2008-021983 filed on Jan. 31, 2008, including specification, claims, drawings and abstract is incorporated herein by reference in its entirety. 
       BACKGROUND 
       [0002]    1. Field of the Invention 
         [0003]    One aspect of the present invention relates to a thin-sized mobile apparatus, and more particularly, to arrangement of an antenna and the like. 
         [0004]    2. Description of the Related Art 
         [0005]    As a type of mobile phone, there is a thin-sized mobile phone. Since the mobile phone is than, the mobile phone may be used closer to a human body. In this case, it is necessary to examine the optimal arrangement of an antenna, in consideration of the effect of the human body on performance of the antenna. 
         [0006]    It is well known that a human body deteriorates performance of an antenna. There is a mobile wireless terminal studied in consideration of such an effect (see JPA-2005-354501 (page 1, page 5, FIG. 1, and FIG. 2, for instance). The mobile wireless terminal is formed in a chest pocket type and has a flat side A and an uneven side B, and the antenna is disposed on the side B. A user puts the mobile wireless terminal in the chest pocket unconsciously to have the flat side A facing a user&#39;s body, and thus an antenna on the side B is away from the user&#39;s body, thereby securing performance of the antenna. 
         [0007]    A non-contact type IC card such as an employee identification card has been well known (see JP-A-11-328348 (page 1 and FIG. 1)). Such an IC card has a printed face for identifying an employee with eyes and has an antenna for a non-contact IC therein. 
         [0008]    In JP-A-2005-354501, a configuration for putting the mobile wireless terminal in a chest pocket is described, but there is no description of arrangement of an antenna in a case of using the mobile wireless terminal with a neck strap hanging on a neck. In JP-A-11-328348, there is no description of antenna communication in a state where an IC card hung on a neck with a neck strap close to a human body, and a user performs communication for non-contact IC generally in a state where the IC card is put close to an external reader/writer device. The IC card does not have a function of a mobile phone, and there is no description about a phone communicating antenna. 
       SUMMARY 
       [0009]    According to one aspect of the invention, there is provided a mobile apparatus including: a main face; a back face opposite to the main face, the back face being printed with visible user information; a thickness from the main face to the back face; an antenna disposed at a position nearer the back face than the main face; and an attachment portion attachable with a wearing tool, the wearing tool, allowing a user to wear the mobile apparatus.
