Abstract

Abstract A facsimile apparatus has a CCU for receiving image data, a decoder for decoding received data, an image memory for storing the decoded data, a CPU for controlling send/receive operation, and a printer for printing received data. High-speed data communication can be performed using a small-capacity memory and a digital transmission line and without data loss.
