Abstract

PURPOSE:To shorten the retrieving time of the contents of a memory by executing retrieval by changing all memory retrieval and skip retrieval to be executed for every index character one after another or as skipping it as shifting in a forward direction or a reverse direction for every one dial memory to represent the group of the dial memory corresponding to an index character. CONSTITUTION:A skip retrieving means 12 makes the displayed dial memory a starting memory based on the retrieving instruction of a key input part 30, and shifts in the forward direction or the reverse direction for every one dial memory to represent the group 20 of the dial memory corresponding to each index character, and displays its contents on a display part 40. Then, a user executes the retrieval by changing the all memory retrieval and the skip retrieval by operating a skip retrieval key 32 or an all memory retrieval key 31. Thus, the retrieving time of the contents of the memory can be shortened.
