Abstract: PURPOSE:To read an original at a high speed, by scanning simultaneously plural photoelectric transducers to obtain an equal scanning time per photoelectric transducer regardless of the number of said transducers, then extracting the picture information equivalent to a line out of a picture information memory. CONSTITUTION:Photoelectric transducers 203a-203d are arrayed to a reading line 201 on an original surface via an optical lens 202, and these transducers are simultaneously scanned by a reading clock 215. The series picture informations extracted by the transducers 203a-203d are quantized by quantizing circuits 204a-204d and then converted into parallel picture informations corresponding to a word of a picture information storage memory 212 by shift registers 206a- 206d respectively. The picture information corresponding to a word is called out of the memory 212 by the control of a multiplexer 209 and then converted into a series data by a shift register 213. Then a series picture signal 214 of a line is delivered. Thus an original is read and transmitted at a high speed.
