ABSTRACT:
The data communication apparatus of the present invention includes a CPU, operation panel, reading unit, image memory for storing read image data, resolution converter for converting stored image data to an optional resolution, telephone communication unit for transmitting data over a telephone line, network communication unit for transmitting data over an internet line, and a printing unit. The resolution converter converts fine detail data to low detail data and sends the low detail data to the telephone communication unit when transmitting data over the telephone line. In this way data reception reliably occurs simultaneously with data transmission. Thereafter, when fine detail request data including resolution data are received over the telephone line, the data are converted to the desired resolution, and sent to the network communication unit. In this way the apparatus attains excellent operationality since fine detail data are transmitted only as necessary.
