1. A data communication apparatus comprising:
- a first communication line;
a second communication line;
first data communication control means for controlling non-voice data communication through said first communication line;
second data communication control means for controlling non-voice data communication through said second communication line, said second data communication control means performing non-voice data communication in accordance with a communication procedure of a type different from that of said first data communication control means;
input means for inputting data;
output means for outputting data; and
mode change control means for changing over said first and second data communication control means so as to connect said first or second data communication control means to said input and output means,wherein said first data communication control means and said second data communication control means can operate in parallel to perform said first non-voice data communication and said second non-voice data communication at the same time.

Abstract
A data communication apparatus includes a reader, a mode change unit, a GIII facsimile controller connected to a telephone line, a GIV facsimile controller connected to a data line, and a printer. The mode change unit includes a mode change controller, a dummy reader, a dummy printer, resolution converters, and switches. The mode change controller connects the GIII or GIV facsimile controller to the reader and the printer. The facsimile controller which is not connected to the reader and the printer is connected to the dummy reader and the dummy printer. The resolution converters convert resolutions of the data so as to match a source apparatus with a destination apparatus.
