1. A data transmitter comprising:
a first communication section performing wireless data communication by an infrared ray according to IrDA Standard;
a second communication section performing, by the infrared ray, wireless data communication that does not comply with the IrDA Standard; and
a switching section that switches between a process performed by said first communication section and a process performed by said second communication section,
said second communication section including:
a management information transmitting section transmitting, in response to a user's instruction for data transmission, management information for managing transmission target data;
a communication capability information receiver section receiving communication capability information indicating communication capability of a device that has responded to the transmission of said management information, wherein the communication capability information is transmission speed information; and
a data transmitting section transmitting a packet including the transmission target data, on the basis of the communication capability information, wherein: said switching section (i) causes said second communication section to perform a process when a user's transmission prosecution command is inputted and (ii) switches to a process performed by said first communication section when said communication capability information receiver section has not received said communication capability information within a predetermined time after the transmission of said management information from said management information transmitting section.
