Claims

[Claims for Utility Model Registration] (1) A sensor unit whose inclination can be changed, means for detecting the position and inclination of a document, means for outputting a control signal to make the sensor unit parallel to the document, and a sensor. 1. A document image correction method for an image input device, comprising means for correcting the tilt of image data read by the unit, and capable of automatically correcting the tilt of the document. (2) A document image correction method for an image input device according to claim 1, wherein the means for correcting the inclination of the image data is constituted by a line buffer capable of offset.
