<P>PROBLEM TO BE SOLVED: To provide an information processor capable of efficiently transmitting and receiving radio waves without providing an unnecessary hole as much as possible by taking a countermeasure for EMC into account when incorporating a short range radiocommunication means such as Bluetooth into the information processor covered with a metallic case body. <P>SOLUTION: This on-vehicle information processor 100 is provided with a radio transmission part 110 performing radiocommunication with the outside, an antenna 202 for radiocommunication transmitting and receiving radio waves for radiocommunication, and an opening part of a slot 201 for a memory card for mounting and dismounting the detachable memory card 203. Size in the longitudinal direction of the opening part is equivalent to 1/2 wavelength being component wavelength of radiocommunication frequency, and the antenna 202 for radiocommunication is arranged along the longitudinal direction in the vicinity of an inner side of the opening part. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
