Abstract:
1. A communication apparatus for communicating with another device by transmitting data through a human body of a user, comprising: a body communication section for communicating with a communication apparatus, other than the communication apparatus, by electrically transmitting data through the human body; an instrument identification information acquiring section for acquiring instrument identification information on the other communication apparatus from the other communication apparatus using said body communication section when the human body touches said body communication section of the communication apparatus and a body communication section of the other communication apparatus; a data communication section for communicating with the other communication apparatus through communication means other than the human body; and a data transmitting section for transmitting data to the other communication apparatus identified by the instrument identification information acquired by said instrument identification information acquiring section using said data communication section, wherein said other communication apparatus is a printing apparatus comprising a body communication section for communicating through the human body, said instrument identification information acquiring section acquires instrument identification information on said printing apparatus from said printing apparatus using said body communication section when the body touches said body communication section of the communication apparatus and said body communication section of said printing apparatus, said data transmitting section transmits the image data to said printing apparatus identified by the instrument identification information acquired by said instrument identification information acquiring section using said data communication section so that the image data stored on the communication apparatus is to be printed, said instrument identification information acquiring section acquires instrument identification information on said printing apparatus multiple times from said printing apparatus using said body communication section when the body touches said body communication section of the communication apparatus and said body communication section of said printing apparatus multiple times during a predetermined time interval, and said data transmitting section transmits the number of sheet for printing corresponding to the number how many times said instrument identification information acquiring section acquires the instrument identification information as incidental information on the image data with the image data to said printing apparatus identified by the instrument identification information acquired by said instrument identification information acquiring section using said data communication section so that a plurality of files of image data stored on the communication apparatus are to be printed.
