Abstract

PURPOSE:To improve transmission efficiency remarkably by sectioning a transmitted original into a transmitted part and an untransmitted part not only in a main scanning direction but also in a subscanning direction. CONSTITUTION:When a scan on a transmitted original is started, a one-line counter 22, while switching its outputs for every width in the main scanning direction of each block, generates a count signal on every line to output a signal which shows which subscanning direction block line is being read at that time. A specified-part latch circuit 20, on the other hand, first outputs a signal which shows which block is specified as to a main-scanning direction block line A. Then, a gate circuit forming circuit 16 compares the output of the circuit 20 with that of the counter 22 to generate and output a gate signal C opening a picture signal gate 14 only while the specified block of the main scanning direction block line A is being read.
