An output control apparatus comprising:
- connection means for connecting to said apparatus detachable memory means which stores a plurality of conversion tables corresponding to respective different code systems, each conversion table being used for converting a character code formed in one of the code systems and input from an external source to said apparatus into an internal code, the memory means also storing (1) a plurality of pieces of character pattern information corresponding to the respective internal codes at respective addresses, and (2) an address table which stores these addresses;
- selection means for selecting a font in response to a font selection instruction;
- first read means for reading one of the internal codes stored in the memory means corresponding to a character code input from the external source to said apparatus using one of the plurality of the conversion tables stored in the memory means corresponding to one of the code systems for the font selected by said selection means;
- and
- second read means for reading one of the plurality of pieces of character pattern information stored in the memory means corresponding to the one internal code read by said first read means, based on the address table stored in the memory means.
An output control method used in an output control apparatus having a connector for connecting to the apparatus a detachable memory which stores a plurality of conversion tables corresponding to respective different code systems, each conversion table being used for converting a character code formed in one of the code systems and input from an external source to the apparatus into an internal code, the memory also storing (1) a plurality of pieces of character pattern information corresponding to the respective internal codes at respective addresses, and (2) an address table which stores these addresses, said method comprising the steps of:
- selecting a font in response to a font selection instruction;
- a first step of reading one of the internal codes stored in the memory corresponding to a character code input from the external source to the apparatus using one of the plurality of the conversion tables stored in the memory corresponding to one of the code systems for the selected font;
- and
- a second step of reading one of the plurality of pieces of character pattern information stored in the memory corresponding to the one internal code read in said first step, based on the address table stored in the memory means.
