Abstract
A central control apparatus and a plurality of terminal apparatuses are connected through a line. In the central control apparatus, a plurality of images are stored in an optical disk in accordance with a hierarchical structure having four hierarchical levels of cabinet, binder, document, and page, and retrieval information constituted by a plurality of keys each for retrieving a corresponding image is stored in a magnetic disk with different title structures (key structures) in units of binders. A desired image is retrieved from the optical disk in accordance with designation of the retrieval information stored in the magnetic disk. A metabinder having a plurality of binders having the same title structure of the retrieval information has a level higher than that of the cabinet. In the central control apparatus, a title table group of the metabinders is stored in the magnetic disk independently of the binders. When an image is to be retrieved in the central control apparatus or a terminal apparatus, the title table group of the metabinders stored in the magnetic disk is retrieved.
