Abstract
An input buffer (16) functions to store one line of data from a scanner (12) while feeding out a previous line to a run length encoder (17). The compressed data is fed from the run length encoder (17) to an output buffer memory (19) having a fixed capacity. The compressed data is fed to the output buffer (19) intermittently while it is fed out of the output buffer (19) continuously for modulation and transmission. In response to a start signal indicating that a line of data has been stored in the input buffer (16), fill bits are fed to the output buffer (19) at high speed until a full signal is generated indicating that the output buffer (19) is full. Then, a sync signal is fed to the output buffer (19) followed by compressed data from the run length encoder (17).
