ージスキヤナ。 A drum that is rotatable about a rotating shaft and carries a document wound around its circumferential surface, an image sensor disposed outside the circumferential surface of the drum, and a control circuit and a signal processing circuit. In an image scanner that scans and reads information such as characters and figures displayed on the document by moving the image sensor in the axial direction of the drum, the image sensor scans and reads information such as characters and figures displayed on the document. The signal processing circuit includes an AND circuit which inputs a signal obtained by A/D converting the outputs of the two sensor elements. An image scanner characterized in that it is configured so that the output of the image scanner is used as a reading signal.
