The mail storage unit 8 is a non-volatile semiconductor memory that stores rewritable emails, and stores received emails and emails created by user operation inputs for each email.

  The character string storage unit 12 is a non-volatile semiconductor memory that stores a large number of character strings for syntax analysis. Here, various morphemes are stored as character strings. This morpheme is the smallest linguistic unit that can be given meaning, and is a part of the word that does not change according to the usage.

  For example, in the sentence “I can't seem to come”, “coming”, “re”, “not”, “yo”, “da”, and “ga” are all character strings as morphemes. Such a character string is stored together with language information. Language information includes part-of-speech information such as verbs, auxiliary verbs, particles, and nouns, and usage information such as usage types and basic forms. More specifically, “verb” is stored as part-of-speech information, “Kabari” is used as a utilization type, and “coming” is stored as a basic form for “coming”. For “re”, “auxiliary verb” is stored as part-of-speech information, “bottom line” is used as a utilization type, and “being” is stored as a basic form.

  The character string extraction unit 9 performs an operation of extracting a character string stored in the character string storage unit 12 from the mail body, that is, a morpheme, in order to parse the mail body of the received mail. Extraction of the character string is started based on, for example, a user operation input while the received mail browsing screen is displayed.

  The template image storage unit 13 is a nonvolatile semiconductor memory that stores various screen display image data as template images. Each template image is stored in association with a character string stored in the character string storage unit 12. Specifically, a correspondence table is stored that includes correspondence relationships between two or more different template images, character strings, and template images. Here, it is assumed that a predetermined character string is inserted in advance in the template image. A character string as the smallest linguistic unit that can be given such a template image, that is, stored in association with a morpheme, compared to storing for each character string that changes according to the utilization form. Since the character string corresponding to one template image is reduced, the storage amount can be suppressed.

  The template image selection unit 10 performs an operation of selecting a template image corresponding to the message content of the mail text. The template image is selected based on the character string extracted from the mail text by the character string extraction unit 9, and a specific template image is read from the template image storage unit 13.

Elected. Then, a template image associated with the selected specific character string is output as an analysis result. If it is difficult to select a specific character string, or if there is no template image associated with the selected character string, an image prepared in advance is read as a template image.

  The mail character display control unit 11 performs control related to the template image screen display, and displays the template image read by the template image selection unit 10 on the display screen in the LCD 5. By displaying the template image corresponding to the message content of the mail body on the screen, the user can easily determine the outline of the mail body from the image without reading the mail body. Here, such an outline of the mail text is called a mail character. That is, the mail character of the received mail is represented by the template image.

  The template image editing control unit 6 performs an operation of inserting characters into the template image. The template image read out by the template image selection unit 10 can be edited based on an operation input by the user, the character string inserted in the image is edited on the editing screen, and a new character is inserted. can do. That is, a character string inserted in advance in the template image can be deleted, or a new character string can be added. In addition, the character string in the template image can be decorated. For example, the character size, the display color of the character, the background color, the display position can be changed, the character can be blinked, and the character string can be displayed in subtitles or swing.

  The mail transmission control unit 7 performs an operation of transmitting the template image displayed on the screen as the mail text of a new mail. That is, the template image read by the template image selection unit 10 or the template image edited by the template image editing control unit 6 can be transmitted to the transmission destination based on the operation input by the user. Specifically, it is possible to send (reply) the new mail by designating the sender of the received mail, which is the template image selection source, as the new mail destination. Here, such an e-mail having a template image in the mail body is called a character mail.
