Abstract: A facsimile apparatus, copier, or other image processing apparatus superior in handling of paperless documents and able to store a large volume of image data, using as a means of storing the image data a small-sized, interchangeable optical disk storage medium known as a "mini-disk". In the case of a facsimile apparatus, a document reader reads the content of the document for transmission as image data, a signal processor compresses the image data and stores it on an optical disk cassette through an optical disk drive. The image compressed data stored in the optical disk cassette may be immediately sent to the destination facsimile apparatus through a modem and line controller or may be sent at a date and time designated for preset transmission. Further, the image data received through the line controller and modem may be printed by a printer or stored in an optical disk cassette.
