Abstract
Abstract An equipment consists of a CRT (60), a keyboard (61), a pointing device (62), a reader (10), a printer (70), a floppy disk device (51), a hard disk device (50), and a main unit which has a reader, printer interface (21), an image compression unit (ICU) (22), a program memory (PMEM) (23), a bit move unit (BMU) (24), an image memory (IMEM) (25), a video RAM (VRAM) (26), a CPU (27), a bus (29) and a communication control unit (CCV) (30). Data comprising code data and image data are divided into different block regions and image data are compressed and coded, depending on the image characteristice. Thus prepared data are stored in the hard disk device.
