Claim Text:
1. An operating device comprising: a plurality of operation keys including character-input keys, a character-conversion key, and an enter key; a processing unit executing a process associated with a pushed operation key from among the operation keys; and a display unit displaying a predetermined image, wherein the processing unit executes processes which allow the display unit to display Japanese syllabary characters associated with the character-input keys which are pushed in a Roman-character input mode, perform conversion of the Japanese syllabary characters into a character string in which Japanese syllabary characters and Kanji characters are mixed when the character-conversion key is pushed, and determine the currently-displayed characters when the enter key is pushed, when the processing unit detects that the character-conversion key and the character-input key, which is located next to the character-conversion key, are pushed at the same time, the processing unit disables the pushing of the character-input key so that the character input of the character-input key is disabled and only executes the process to convert the Japanese syllabary characters, which are input before the character-conversion key and the character-input key are pushed at the same time, into a character string in which the Japanese syllabary characters and the Kanji characters are mixed, the process being associated with the character-conversion key, both disabling the character input of the character-input key and executing the process associated with the character-conversion key are performed based on pushing alone of the character-conversion key and the character-input key, which is located next to the character-conversion key, at the same time, and when the processing unit detects that the character-conversion key and the character-input key located next to the character-conversion key are pushed at the same time, the character of the character-input key which is pushed simultaneously with the pushing of the character-conversion key is displayed once on the display unit in addition to the process to convert the Japanese syllabary characters into the character string in which the Japanese syllabary characters and the Kanji characters are mixed, the process being associated with the character-conversion key, and then, the character is removed from the display.
