Abstract
A data transmission apparatus includes a plurality of I/F (interface) units for converting data into a predetermined transmission format and transmitting it to an external device, a power source section for supplying electric power to the I/F sections, a control section for controlling the power source section, and detection sections are connected to the I/F units for outputting connection detecting signals to the control section. The control section outputs a power control signal to the power source section so as to operate in such a manner that when the control section has detected that at least one of the I/F sections is in a connecting state, the electric power is supplied to the I/F sections, and when the control section has detected that none of the I/F sections is in a connecting state, no electric power is supplied from the power source section to the I/F sections.
