A device for recording and retrieving images corresponding to a plurality of documents is based on an apparatus which generates images which respectively correspond to a plurality of original documents, rotates those images to provide a more meaningful image for the user, and records those images on a recording medium. The image corresponding to each document which is scanned subsequent to the first document is rotated based on whether the image corresponding to the first document is rotated or not. A comparison between a pixel count on the image corresponding to the first document may be compared with a pixel count corresponding to each subsequently generated image to determine whether such rotation should be performed. Original documents are scanned in the sub-scanning direction and rotated after scanning to increase scanning speed. Retrieval data for each image is stored for retrieval purposes.
