This paper relates to a digital telephone set and its electronic telephone directory registration method.

(2) As a convenient service for conventional technology transmission, we will develop the repertoire function to register, record, and maintain not only telephone numbers but also names, company names, etc. as data.

Several telephones have been devised that provide the function of displaying an electronic telephone directory. The types of characters that can be registered and displayed range from simple characters such as alphabets, numbers, and kana.
Although there are various types of high-performance devices that can also express names in kanji, there is a strong demand for kanji expressions for names, etc. for convenience in actual use.

However, with conventional telephones of this type that can express kanji,
It requires a means to generate a kanji font and a means to input or select kanji, and has the following drawbacks.

■ Requires a kanji ROM for generating kanji fonts, a keyboard for input/selection, and a kana-to-kanji conversion function or romaji-to-kanji conversion function to convert kana or romaji input from the keyboard into kanji, making the equipment expensive. It is large and cannot be made smaller.

■ When using the above-mentioned kana-kanji or romaji-kanji conversion as a manual method, be careful of homophones, and when entering codes using a dial, check the kanji code.

This will impose a burden on the user.

(3) Purpose of the Invention The purpose of the present invention is to solve two or more drawbacks, to eliminate the need for direct operation by the user in registering names, etc. expressed in kanji, and to make the device more compact and economical. An object of the present invention is to provide a digital telephone with an electronic telephone directory function.
