IMAGE READING APPARATUS CAPABLE OF DISPLAYING FOREIGN MATTER POSITION AS IMAGE

摘要

An image reading apparatus that is capable of displaying in detail, as an image, a foreign matter position where an image reading failure could be caused. The image reading apparatus has a main scanning index plate and a sub-scanning index plate disposed adjacent to a reading glass and extending in main scanning and sub-scanning directions. These plates have scales that equally divide a surface of the reading glass in the main scanning and sub-scanning directions. When foreign matter is detected, a foreign matter detection message, a foreign matter area image, and position information representing a foreign matter area position are displayed on an operation panel. Based on the displayed image and position information, a user can easily recognize a cleaning object area on the reading glass surface while referring to the scales of the index plates.
