PROBLEM TO BE SOLVED: To provide an arrangement method of a key-in device capable of displaying a code composition such as words and phrases on a display screen with a less pressing times as compared with a conventional one. SOLUTION: This method comprises: a commonly-used code distribution step for dividing commonly-used codes into plural commonly-used code groups; a specially-used code distribution step for dividing specially-used codes into plural specially-used code groups; an installation step of keys for sequentially installing and arranging plural keys more than the number of keys used for key-in of the codes; a first function imparting step for sequentially selecting the numbers of keys as ones for key-in from plural keys to sequentially distribute the keys as the commonly-used code keys so as to correspond to the plural commonly-used code groups, thereafter distributing the keys as the specially-used code keys to keys for key-in excluding the commonly-used code keys so as to correspond to the plural specially-used code groups and thereby allowing the code group corresponding to the function key by key pressing to be displayed; and a second function imparting step of the keys for key-in for allowing the code corresponding to the arrangement order of the code group displayed by key pressing to be selected and displayed.
