Abstract

An image filing apparatus comprises a drive device which is loaded with an optical disk capable of storing a plurality of signals, and with which image signals representing images and subsidiary information belonging to each of the images are stored on the optical disk and read therefrom. When the image signals and the subsidiary information corresponding to each of the image signals are stored on the optical disk loaded into the drive device, a data base constructing device constructs an image signal retrieving data base from the subsidiary information such that an image signal corresponding to the subsidiary information may be retrieved. A storage device stores the data base such that it can be rewritten. A data base construction preventing device inspects the subsidiary information when an image signal and the subsidiary information corresponding to the image signal are stored on the optical disk loaded into the drive device. In cases where the subsidiary information has been found to be abnormal, a data base is prevented from being constructed from the subsidiary information.
