An image-reading device includes a platen glass for supporting a document, an end glass adjacent to the platen glass, a sheet member that connects bottom surfaces of the platen glass and the end glass, a feeder for feeding a document to the image-reading device, a carriage that includes a sliding member, a rod lens array mounted on the carriage, and a photoelectric transfer device for reading an image of the original document formed by the rod lens array. The carriage is biased against the platen glass and the end glass through the sliding member and moves relative to them. A controller drives the carriage at different speeds, one less than half the other, so that the carriage is moving slowly when the sliding member contacts the sheet member, thereby avoiding problems of wear of the sliding member and loss of synchronism of the motor that drives the carriage.
