を可能とする。The image sensor used for these owtt*vs is generally a one-dimensional image sensor], which electrically scans in the main scanning direction and captures the -row OVa image O direct information in a temporally aligned manner. The two-dimensional O original image is temporally arranged in a line by sub-scanning (relative movement with the WR assembly section by Senna) and converted into a nine-dimensional signal. Then, the signal is sent to other O devices (recording device, mailbox, etc.) via an electric transmission line, making it possible to print, display, etc.

に並んだm像信号Sが出力される。That is, first, by switching the automatic circuit changeover switch 5 to [10 image center tccI], a series of signals are given from pulse 114 to image center CC1, and a pulse is applied to image sensor CCIVc. The club's reading is done. As soon as this reading is completed, the switch 5 automatically switches the circuit to the 20th image 7? The mode is switched to CC2, and the second image sensor CC2 is given a continuous pulse of signals from the Ah source 6, and the second half of the document information BOI! by the image sensor CC2 is given. The deal will be made. By simply sending the bladder signals S to the two image sensors, one image sensor can generate m image signals S that are aligned in time, as in the case of m. is output.
