Abstract
A document transport device includes a placement portion, a slide member, a movable piece, and a detector. A document is to be placed on the placement portion. The slide member includes a document guide that contacts one lateral side of the document which is placed on the placement portion. The movable piece is provided to the slide member, and includes a shading pattern composed of plural patches that have plural densities corresponding to plural document sizes and having plural adjacent patch density differences that are different from each other. The detector detects a density of the shading pattern, and outputs an output signal for document size recognition.
