<p><P>PROBLEM TO BE SOLVED: To provide a portable machine which can be reduced in thickness while maintaining strength thereof. <P>SOLUTION: The portable machine body 11 having electronic components for communication accommodated therein is formed of an upper case 12 and a lower case 13 having the apertures. Both cases 12, 13 are joined with each other to close the apertures thereof. At the external circumferential edges of both cases 12, 13, holding frames 16 are provided to be removable to hold both cases so that these cases are never isolated. The holding frame 16 is formed in the annular shape to surround the external circumference of the mobile machine body 11. At the external circumferential edges of both cases 12, 13, the projected portions 12c, 13c extending along the circumferential direction are formed. These projected portions 12c and 13c are engaged to be removable with the engaging grooves 17d, 18d formed at the internal circumferential surface of the holding frame 16 under the relation of the convex and concave portions. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
