Abstract:
1. A font management system comprising: a pointer table for storing start addresses of bitmap data assigned to all character codes included in a given coded character set; and a processor which, upon receipt of an input of a character code to be displayed, acquires a start address of bitmap data assigned to the input character code by reference to the pointer table and displays a character on a display device, wherein the pointer table includes a first pointer table and a second pointer table; the first pointer table is formed by means of deleting at least some of character code areas, where bitmap data are not present, from an initial pointer table having records of fixed length where are stored start addresses of bitmap data assigned to all the character codes from start to end; the second pointer table stores a relationship between positions of undeleted, remaining character code areas in the first pointer table and positions of the same in the initial pointer table; and the processor accesses the second pointer table to thus acquire an address of the input character code in the first pointer table, and directly accesses the corresponding record in the first pointer table by use of the acquired address to thereby acquire the start address.
