Abstract
Abstract The information searching apparatus in accordance with the present invention comprises: a memory device having a plurality of banks and containing a plurality of types of information data to be searched, as arranged in block; a table memory device containing, in table, the banks serving as the basis of the information to be searched, the number of changed banks and address data; and a table reading device for reading tabled information from the table memory device. This information searching apparatus is so arranged as to search the target information to be searched by obtaining the base bank information based on the tabled information from the table memory device, and by obtaining the number of changed banks and the address data of the base bank information. Further, this apparatus is arranged such that the user may learn synonyms and antonyms, or the translated terms, the phonetic symbols or the like of index words in dictionary data. Such data may be searched in a short period of time without any complicate operations, thereby to improve the learning efficiency.
