Abstract
PURPOSE: To obtain a telautograph which can perform high-speed transmission, by constituting this unit by a transmission part, which synthesizes signals from a photoelectric converter, a line information generator, a block information generator, etc., and transmits them, and a receiving part which decodes and recording these signals.
CONSTITUTION: In transmission part I, photoelectric conversion-type scanner 51 is controlled by scanning controller 52, and one scanning line on pictures and writings is scanned twice. The first- time conversion electric signal is read into black picture element counter 53, and the appearance probability of black picture elements is counted, and line information is generated in 54 and is tramsmitted through adder 55 and modulator 56. The second-time scanning is performed during this transmission, and block information is generated in 57 on a basis of the number of bits in one block determined by the first-time scanning, and picture infomation required for non-skip transmission is written into one line memory 58. Next, information of memory 58 is read out by memory controller 59 and are added to signals from synchronizing signal generator 60 in 55, and they are transmitted. In receiving part II, the operation reverse to transmission is performed, and respective information are decoded and recorded by recorder 68 through line memory 67.
