Abstract
A fabric inspection device includes a sheet conveying portion, an image reading portion, a timing control portion, a storage portion, a comparing control portion, and a display portion. The image reading portion reads a plurality of images of the same pattern recorded repeatedly with a predetermined pitch on a recording sheet conveyed by the sheet conveying portion. The timing control portion regulates the timing of image reading by the image reading portion. The storage portion stores the plurality of images read by the image reading portion. The comparing control portion takes, out of the plurality of images stored in the storage portion, part of an image continuously recorded on the recording sheet corresponding to the forefront one pitch as a reference image and compares the image data of a comparison image recorded later than the reference image with image data of the reference image to check for image defects.
