<p>PURPOSE:To down-load control information in short time by writing write information directly via a bus in a nonvolatile memory which is electrically erasable and writable. CONSTITUTION:In the case of rewriting the data of EEPROM 6, the down- loading data holding device 3 containing ROM, which holds the data written in ROM 6, and a magneto-optical disk device 2 are connected via a connecting terminal connected to the bus, and the data from ROM 10 to ROM 6 is transferred via the bus.</p> |
