IMAGE READER, CONTROL METHOD OF SAME, AND CONTROL PROGRAM OF SAME |
摘要 |
PROBLEM TO BE SOLVED: To provide an image reader capable of reading a high quality image without any influence even though dirt and dust are attached to contact glass of an image reading part. SOLUTION: A reading sensor 251 reads a white reference face and a black reference face of a reference plate 211 to detect dust, and the image reading sensor 251 is moved to a place unaffected by the dust to read an image. Image data of an original part is read by reading image data temporarily stored in a memory from a position corresponding to the moving amount of the image reading sensor 251.
