On the other hand, when the transmission / reception unit 11 receives the mail data transmitted from another portable telephone device, the control circuit 8 displays the mail data on the display 6 and writes the mail data in the storage unit 12 in the order of reception. Is stored as a reception history.

Next, the operation of this embodiment will be described with reference to FIGS. FIG. 1 is a flowchart showing the control contents of the control circuit 8 when the user performs a search process on a plurality of mails stored in the storage unit 12. FIG. 2 shows an example of a screen display on the display 6 accompanying the search processing.

When the user selects "mail search" from the processing mode menu displayed on the display 6, the flowchart shown in FIG. 1 is executed. First, as shown in FIG. 2A, the control circuit 8 causes the display 6 to display a screen for allowing the user to select “sent mail” or “received mail”. Then, for example, when the user operates the numeric keys of the key operation unit 3 to select “YE”, the control circuit 8 determines “YE” in step S1.
S ", the flow shifts to step S2, and the received mail is searched. If the user has selected "NO" in step S1, the process proceeds to step S3 to search for an outgoing mail.

When the user selects either or (in this case) on the screen of FIG. 2A, the control circuit 8 switches the screen of the display 6 as shown in FIG. 2B. For example, a menu of search conditions such as "chronological order", "sender name search", and "free word search" is displayed. Then, the control circuit 8 waits for the user to select one of the steps (steps S4 and S4).
5) If the free word search is selected, "YES" is determined in the step S4, and the process shifts to the step S6.
The screen of the display 6 is switched as shown in FIG.

That is, a message “What is a free word?” Is displayed on the screen to prompt the user to input a search keyword. When the user inputs, for example, “meeting”, the control circuit 8
Determines "YES" in step S6 and proceeds to step S7 to search and pick up a received mail stored in the storage unit 12 that includes the keyword "conference". As shown in FIG. 2 (d), four screens are displayed on the screen of the display 6 (step S8). Steps S4 and S6 correspond to search condition input means.

[0024] In this case, "the meeting on xx / xx is 1 ...",
"Meeting with XX Trading ...", "As a result of the board meeting,
.. ", Only a few characters (for example, 8 characters) are displayed from the beginning of each mail. If five or more e-mails satisfying the conditions are found as a result of the search, the screen is scrolled by operating the scroll key of the key operation unit 3 (or the number key of “5” or more is turned on). And) other emails can be displayed.

Then, for example, the mail displayed on the screen shown in FIG. 2D is the mail desired by the user, and when the user selects the mail, the control circuit 8 proceeds to step S.
9 is determined to be “YES”, and “○ / month / day meeting held at 10:00”
Will be held in the third conference room. Please attend. ", The whole sentence of the received mail finally selected (as much as can be displayed on one screen) is displayed on the display 6 (step S10, see FIG. 2E), and the process is terminated.

Further, for example, if there is no mail desired by the user among the mails searched and displayed in steps S7 and S8, when the user turns on the numeric key "0", for example, the control circuit 8 Is determined to be "NO" in step S9, the process proceeds to step S4, and the display screen of the display 6 is returned to the previous search screen (in this case, FIG. 2C) to reset the search condition. I do.

On the other hand, if the user selects other than the free word search during the loop of steps S4 and S5, the control circuit 8 executes the search based on the search conditions set in advance in or. I do. For example, when the user selects “sender name search” on the screen of FIG. 2B, the control circuit 8 switches the screen of the display 6 to “Sender name search” as shown in FIG. Is displayed, prompting the user to enter a sender name.

When the user inputs, for example, "Yamada", the control circuit 8 determines "NO" in step S4 and "YES" in step S5, and proceeds to step S7.
Searches received mail under the condition of sender name = Yamada. still,
Steps S4 and S5 correspond to search condition selection means.

If there are a plurality of search results corresponding to the sender name = Yamada, for example, FIG.
As shown in "Taro Yamada", "Jiro Yamada", "
A name such as "Hanako Yamada" is also displayed on the display 6 (step S8).

At this stage, since the search is in the middle of the search, the control circuit 8 determines "NO" in step S9 and returns to step S9.
Move to 4. Then, if the user, for example, "Taro Yamada"
Is selected, "NO" is determined in step S4, and "YES" is determined in step S5, and the process shifts to step S7 to search for a received mail under the condition that the sender name is Taro Yamada. Then, as shown in FIG. 2 (h), if there are a plurality of e-mails corresponding to the search condition, "Let's go skiing ...", "Let's have a drink ...", "How are you?" Such a plurality of e-mails are displayed on the display 6.

When the search is performed under the condition that the sender name = Yamada, and the sender name is only “Taro Yamada”, the screen of FIG. h) may be displayed.

Then, when the user selects on the screen of FIG. 2 (h), the control circuit 8 performs the following operation as shown in FIG. 2 (i).
The full text of the e-mail such as “How are you? I am tired.

As described above, according to the present embodiment, the control circuit 8 controls the plurality of received mails stored in the storage unit 12
The transmitted mail is searched according to the search condition set by the user, and the search result is displayed on the display 6. Therefore, even if a large amount of mail is present in the storage unit 12, the user can select the desired mail. Can be easily read and confirmed.

Further, the user can operate the key operation unit 3 to select and set search conditions from a plurality of predetermined ones while referring to a menu displayed on the screen of the display 6. Therefore, the search can be easily performed. Further, each time the control circuit 8 performs a search based on the set search condition, a new search condition can be selected and set. By narrowing down the search results by giving search conditions in a specific manner, a desired mail can be efficiently searched. In other words, even when the screen size of the display 6 is limited by the entire size of the mobile phone device 1, the user can perform the search without inconvenience.

Further, according to the present embodiment, by operating the key operation unit 3, a free word search in which a user can arbitrarily input and set search conditions is possible, so that the degree of freedom of search conditions is increased. Search efficiency can be improved.

In addition, according to the present embodiment, the control circuit 8
Displays only a certain number of characters from the beginning of the mail corresponding to the search condition on the display 6, so that even if the mail does not have a particular title, displaying a certain number of characters from the beginning of the mail usually indicates the user However, since it is a mail that has been seen once, the content can be specified. Then, even when there are a plurality of mails corresponding to the search condition, a large number of mails can be displayed on the display 6 at a time, so that the search can be easily performed.

The present invention is not limited to the embodiment described above and shown in the drawings, and the following modifications or extensions are possible. It is preferable to display the number of messages corresponding to the search condition, such as "the number of hits, 6", on the screen initially displayed on the display 6 in step S8. With such a configuration, even when the number of messages corresponding to the search condition exceeds the number of messages that can be displayed on the display 6 at one time, by switching the screen of the display 6 as necessary, the user can perform the search. Can be referenced without omission. In the free word search, for example, on the screen of FIG.
The search may be performed based on those OR conditions or AND conditions. Also, as shown in FIG. 2D, when the search result is once displayed with a single keyword “meeting” and then the screen returns to the screen of FIG. May be able to input a second keyword.

For example, the storage unit 12 may be in a state where received mails and outgoing mails are mixed and stored without distinction. The search processing for the transmission message may be performed as necessary in a case where the transmission message is also stored in the storage unit. The display unit is not limited to displaying only a certain number of characters from the beginning of the message corresponding to the search condition, and the entire text of the corresponding message may be displayed one by one. Further, the processing is not limited to the stepwise search, and the processing may be terminated when the result of one search is displayed. The free word search may be performed as needed.
