Abstract
Abstract An electronic device for displaying accent is disclosed which is useful for displaying words and sentences by use of a multiple-digit display device. In the respective word display parts of the multiple-digit display device, additional symbols for an accent display are provided. Alphabet characters can be expressed as five-bit codes. In one disclosed embodiment, an additional sixth bit is used to indicate the presence or absence of an accent associated with the character represented by the remaining five bits. In another disclosed embodiment, accented vowels are each represented by five-bit codes that are different from the five-bit codes representing the same vowels without accents, so that no sixth bit is necessary. Words are displayed while discriminating a word with accent from a word with no accent.
