Abstract

PURPOSE: To shorten the time of input information extraction processing while reducing memory capacity needed for an information processor side, by previously assigning the existence range of needed picture information by a liquid-crystal plate on an original paper face to be transmitted by a facsimile equipment.
CONSTITUTION: As unneeded parts on an original are sequentially assigned by light pen 2, address pulses reading an address on a liquid-crystal plate by a raster scanning on liquid crystal plate 7 are input from light-pen reading circuit 8 to microcomputer 11, and converted into the address of liquid-crystal 7, which is stored in memory 10 being controlled by micro computer 11. Micro computer 11 reads the address on the liquid-crystal plate stored in memory 10 to control liquid-crystal scanning circuit 9 and liquid-crystal plate 7 at parts assigned sequentially by light pen 2 is made opaque to erase unneeded parts.
