  If it is not the mail to be registered as the secret mail (step S405; N), it is possible to select whether or not to end the mail menu.

    If there is an instruction to end the mail menu (step S410; Y), the storage process ends.

    If there is no instruction to end the mail menu (step S410; N), the process returns to the input of step S404.

  With respect to the mail reading processing in FIGS. 9 and 10, the same configuration and operation processing as in the first embodiment is performed.

  As described above, according to the third embodiment, after the received mail and the attached file are stored in the normal received mail storage unit 42 and the normal data storage area R7, the user confirms the contents, and the necessary mail and Only the attached file can be selected and stored in the secret received mail storage unit 43 and the secret data storage area R3 that require authentication of the personal identification number.

  As in the example of the second embodiment, the user can manually sort any mail that cannot be sorted by the automatic sorting condition setting.

  Since all received emails are once stored in the normal received email storage unit 42, when checking a large number of received emails at a time, the user only has to check one folder, which can prevent reading errors. An effect different from the example of the second embodiment is obtained in that it is a method.

  In this way, it is possible to provide a communication terminal device that is highly convenient and has a high security and management function for mail and data.

[Modification of Embodiment]
In the first to third embodiments, as shown in FIG. 6, the mail reception folder and the transmission folder are divided into a secret folder and a normal folder, respectively. In addition, the mail text is stored in the same folder together with the title and the like.

  As a modification of the memory configuration in the mail data storage area R2 in FIG. 4, a secret mail (SCF in the figure) is identified as a secret mail as shown in FIG. It may be configured to be stored in one folder, and may be configured to store e-mail text and e-mail information such as a title in another folder.

  As shown in FIG. 15, there are three physical folders: a reception folder 61 for storing the title of the received mail, a transmission folder 62 for storing the title of the transmission mail, and a mail body folder 63 for storing the mail body of the transmission / reception mail. However, since it can be logically handled as four folders as shown in FIG. 11, the read processing shown in FIGS. 9 and 10 can also be performed.
