An original reader has first and second arrays of line sensor chips having reading positions shifted from each other, a moving mechanism for moving the line sensors and an original relative to each other in accordance with a selected magnification of the original, CCD registers for delaying outputs from the first array of line sensor chips to match them with those from the second array of line sensor chips, and an analog switch for controlling the shifting operation of the registers. The reader can read an original image and reproduce the read image without adverse effect of an error between the reading positions of the sensors.

An original reader comprising: a plurality of line sensors each consisting of a plurality of photosensor elements, said line sensors being arranged such that lines read at a given instant by adjacent ones of said line sensors mutually differ; means for moving said plurality of line sensors and an original relative to each other in a direction perpendicular to a scanning direction of said plurality of line sensors at a speed corresponding to a variable reading magnification of the original; and means for delaying by a delay time an output from one of said line sensors which scans a line of the original prior to scanning of that line by a second one of said line sensors, said delay time being varied in accordance with the reading magnification of the original.
