Problems solved by technology

In this case, unless the user is properly notified when the reading process is interrupted, the cause of the interruption of the reading process, which is the mixed state of the original, cannot be resolved
Therefore, no matter how the user adjusts the position of the document to prevent the document from being skewed, the reading process cannot be continuously performed

Abstract

The invention relates to an image reading apparatus, an image reading method, and a storage medium. In a case where a skew of a document being conveyed is detected by a detection unit, an image reading apparatus notifies that documents having different sheet widths may be included in documents stacked on a stacking unit.

Description

technical field [0001] Aspects of the embodiments relate to an image reading device, an image reading method, and a storage medium that detect skew of a document. Background technique [0002] There is provided an image reading device that conveys a document through an automatic document feeder (ADF) to read an image of the document, and generates image data by reading the document. With such an image reading apparatus, if the originals are stacked on the stacking unit (ie, manual original feeding unit) with the originals skewed, a jam may occur when the originals are conveyed, which may damage the originals. Also, jammed originals may damage the rollers inside the ADF and nearby transport guide members. As a technique for solving the above-mentioned problems, Japanese Patent Application Laid-Open No. 2007-331908 discusses a printing apparatus that detects the skew of a document by two sensors arranged in line symmetry with the conveying direction, and based on The conveyi...
