Electronic dictionary having means for linking two or more different groups of vocabulary entries in a closed loop

摘要

An electronic dictionary comprising a dictionary memory having multiple memory locations each of which comprises a vocabulary-data memory location and an address-number memory location corresponding to each other. The vocabulary-data memory locations store vocabulary data representative of different vocabulary entries including plural groups of entries, each group consisting of the entries of the same nature which include at least one special entry. The vocabulary entries of each group are retrieved in a predetermined order. Each of the address-number memory locations corresponding to the entries of each group except the special entry stores address-number data representative of an address of the vocabulary data which is retrieved next, whereby the entries of each group are successively retrieved. Special data is stored in the address- number memory location corresponding to the vocabulary-data memory location which stores the special entry. If the special data is retrieved upon retrieval of the special entry, the currently retrieved group of entries is linked with another group by a control device which designates the address of an entry of this another group based on the special data, and retrieves the vocabulary data stored in the vocabulary-data memory location at the designated address.
