    摘要: The present invention aims at restoring backup data in a predetermined order and avoiding damage from being given to the system even when the backup data are destroyed. Flags Ferr and Feeprom and a variable i stored in a DRAM are initialized (S1 to S3). When the variable i is smaller than the number n of EEPROMs (hereinafter referred to as “PROM(s)”), the ID code of a PROM in question is read and loaded into the DRAM (S4 to S6). When the variable i equals the number n, the variable i is cleared (S7). Then, a variable j is initialized (S9), and it is determined whether or not each PROM ID stored in the DRAM matches with a mask ROM ID until the variable j becomes greater than the number n of PROMs (S11). If the answer is “No”, the variable j is incremented (S13), while if “Yes,” a number corresponding to the variable j then assumed is loaded into the DRAM as the flag Feeprom (S14). Data in the PROM in question is transferred to an area of the DRAM in which is stored the PROM ID matching with the mask ROM ID.

    摘要: An optical scanning apparatus includes a light source; and a rotational polygon mirror having N reflecting surfaces, the rotational polygon mirror being configured to reflect a light flux emitted from the light source so that a scanning surface is scanned along a main-scanning direction with reflected from the rotational polygon mirror.
