Abstract
Font packing device and font unpacking device aims at storing a bit map font at a high packing ratio, and processing and unpacking the packed data with a simple hardware configuration at a high speed. Bit map data of each character is equally divided into a plurality of blocks. If the plural blocks share the same bit map data, then the bit map data is stored for only one block collectively. At this time, addresses indicating the storage area of the shared bit map data for the other blocks are stored. If a bit map data is used for one block only and not shared with any other blocks, then the data is stored with an address indicating the storage area.
