IMAGE READING DEVICE CAPABLE OF PERFORMING ROTATION PROCESS ON READ IMAGE APPROPRIATELY

摘要

An image reading device conveys a first sheet and second sheet in a conveying direction. The first sheet has short sides extending in the conveying direction and long sides extending in a main scanning direction. The second sheet has long sides extending in the conveying direction and short sides extending in the main scanning direction. The image reading device reads an image on a sheet at a reading position and detects the sheet at a detecting position. A distance between the reading position and the detecting position is smaller than a difference between the short side of first sheet and the long side of second sheet. The image reading device rotates the read image if a sheet is not detected when the predetermined length worth of image is read. The read image is not rotated if a sheet is detected when the predetermined length worth of image is read.
