Abstract

PURPOSE:To eliminate an unnecessary blank part on an original automatically by providing an unnecessary-blank detecting circuit which sends a detection signal when the continuation length of the blank part exceeds a prescribed value, and interrupting the writing of read data in a memory in response to the detection signal. CONSTITUTION:A reader 1 is a hand-scanner type moved on an original 2 in its held direction, and an image sensor combined optically with it scans the original 2 at a high speed in a direction Y perpendicular to the movement direction X of the reader 1 to read a two-dimensional figure. Then, a readout control circuit 4 controls the scan of the image sensor and performs the preprocessing of a video signal obtained from the image sensor to output read data SD, and also to output an X-directional signal HSC by the rotation of a length measurement roller 3. Further, an unnecessary-blank detecting circuit 9 monitors the continuation length of a blank part in the direction X and, when the continuation length exceeds a prescribed value, sends a detection signal to interrupt the writing of the read data in a memory 6 which corresponds to this signal.
