发明名称 Character string identification device with a memory comprising selectively accessible memory areas
摘要 In a character identification device for identifying an input character to produce an identified code, a memory circuit (40) decides a match between the input character and stored characters preliminarily stored therein to produce a character match signal. An encoder (50) encodes the character match signal into the identified code. The memory circuit (40) includes a plurality of memory areas (41 to 44). A memory area selector (54) selects a specific memory area in response to a selection signal produced from a signal producing circuit (52) to supply the input character to the specific memory area. In a character string identification device, a processing circuit (90) uses the character match signal to generate a string match signal which is encoded into the identified code by the encoder (51). The processing circuit (90) may include several processing sections (91 to 94) equal in number to the memory areas. An activating arrangement (182) activates a particular one of the processing sections that corresponds to the specific memory area. The identified code may be provided to the memory circuit as the input character through an interruption switch circuit (226).
