Abstract

PROBLEM TO BE SOLVED: To provide a terminal device capable of reducing transmission of mails with error destinations.SOLUTION: A terminal device with a mail transmission function stores one or more mail addresses indicating transmission destinations in association with target flags indicating whether transmission destinations indicated by the mail addresses are targets of an error transmission prevention function. When a specific operation is performed on an operation unit that executes a mail transmission operation, if mail destinations include at least one mail address associated with the target flag indicating that the mail address is a target of the error transmission prevention function, the terminal device does not execute the mail transmission.

Description

  The present invention relates to a terminal device having a mail transmission function, and more particularly to a technique for preventing erroneous mail transmission.

A function of transmitting electronic mail (hereinafter simply referred to as “mail”) using a network such as the Internet is indispensable for a terminal that can use a network such as a current mobile phone.
The mail transmission function is convenient in that mail can be transmitted by a transmission instruction by simple character input and simple button operation (for example, pressing a transmission button). On the other hand, if the user accidentally presses the send button, the mail may be easily sent incorrectly.

  Therefore, Patent Document 1 discloses a technique for preventing erroneous mail transmission. Specifically, in Patent Document 1, when there is a mail transmission instruction, it is determined whether or not a mail is being created by parsing the content (text) of a mail to be transmitted, and further a mail indicating a transmission destination. The address is also analyzed to determine whether it conforms to the e-mail address notation rules. When it is determined that a mail is being created, or when it is determined that the destination mail address does not conform to the notation rules, control is performed so that the mail is not transmitted.

  This prevents erroneous transmission of mail.

Japanese Patent Laid-Open No. 5-241993

  Here, a situation as shown in FIG. 14 is assumed. FIG. 14 shows that the mobile phone 1000 having a touch panel function can input characters in the body of an email. In the cellular phone 1000 of FIG. 14, a transmission button B1100 is arranged as an operation button together with a button for character input. For example, FIG. 14 shows a situation in which an email notifying about the holding of a meeting is being created.

The text of the mail is complete as a single sentence, but the meeting time, place, etc. have not yet been entered, and the content of the mail is incomplete. In addition, the destination conforms to the mail address notation rules.
In such a situation, if the user erroneously presses the transmission button B1100, erroneous transmission cannot be prevented even using the technique disclosed in Patent Document 1. This is because, as described above, since the sentence is completed, it is not determined that the mail is being created by the syntax analysis, and the mail destination also conforms to the notation rule. For this reason, as shown in the figure below, the mail is transmitted, and for example, a message indicating that the message has been transmitted is displayed.

  In other words, as shown in FIG. 14, if the send button B1100 is displayed in a state where the text input of the mail text is acceptable, the mail can be sent immediately after the mail is created, but the creation of the mail as shown above is completed. If not, the transmission button B1100 may be pressed and erroneous transmission may occur. If it is erroneously transmitted, the partner may feel uncomfortable in the relationship between the sender and the partner. For example, this is a case where the destination of the mail is a company boss.

  In view of the above problems, an object of the present invention is to provide a terminal device and a method for preventing erroneous mail transmission that can reduce erroneous mail transmission.

  In order to achieve the above object, the present invention is a terminal device having a mail transmission function, in which one or more mail addresses indicating a transmission destination and a transmission destination indicated by the mail address are targets of an erroneous transmission prevention function. When an address storage unit that stores a target flag indicating whether or not there is associated with an address storage unit, an operation unit that performs a mail transmission operation, and a specific operation is performed on the operation unit, the corresponding target flag is If the e-mail address indicating that it is the target of the erroneous transmission prevention function is not included in the mail destination, an e-mail is sent, and the corresponding target flag indicates the target of the erroneous transmission prevention function. Is included in a mail destination, a transmission processing unit that does not perform mail transmission is provided.

  According to the configuration described above, the terminal device can reduce erroneous transmission of mail.

The display unit 4 includes a touch panel 10 having a function of detecting a point touched with a finger.

  Here, the detection method of the touch position of the touch panel is a self-capacitor type electrostatic capacity method. Since the electrostatic capacity method is a known technique, it will be briefly described here. In the capacitive touch panel, a plurality of transparent electrodes are arranged in each of the x-axis direction and the y-axis direction shown in FIG. When a certain point is touched, charges are accumulated in the transparent electrode in the x-axis direction and the transparent electrode in the y-axis direction immediately below it, and the rising edge of the pulse signal input from the pulse drive buffer (for example, from 0V to 5V) (Rise) becomes dull. That is, the periodic change in voltage is disturbed. By detecting this change, it can be seen at which position (which button or which icon) of the touch panel is touched.

Here, an example of a character input display and a character input method will be described.
At the time of mail creation, a screen as shown in FIG. In the destination column D100 and the Cc column D101, the destination of mail transmission is input, the subject of the email is input in the subject column D102, and the content of the email is input in the content input column D103.
Further, a key input unit D104 is displayed below the content input column D103, and an input to each column is made by pressing a button displayed on the key input unit D104. Specifically, in the case of Japanese character input, character input is performed by a 5-touch input method. Here, since the 5-touch input method is a known technique, a detailed description thereof is omitted here. For example, by pressing a button displaying “A”, the character on that line can be input. For example, if you press the button once, “A” becomes a candidate for the input character. If you press the button twice, “Yes”, if you press it three times, “U”, if you press it four times, “E” if you press it five times. “O” is a candidate for input. Then, by pressing another button, the displayed input candidate is confirmed.

When it is determined that the mode is the automatic setting mode (“Yes” in step S10), the group distribution unit 34 registers the mail address to be registered in a predetermined group (here, other group) (step S15).
When it is determined that the mode is the non-automatic setting mode (“No” in Step S10), the group distribution unit 34 registers the mail address to be registered in the group designated by the user (Step S20).

When it is determined that the e-mail address to be registered is not new (“No” in step S5), the group distribution unit 34 ends the process without performing registration.
(2) Error Transmission Prevention Function Setting Processing Here, mail error transmission prevention function setting processing will be described with reference to the flowchart shown in FIG.

The first setting unit 31 determines whether or not an instruction for setting an erroneous mail transmission prevention function has been received in accordance with an instruction from the user (step S50).
If it is determined that it has been accepted (“Yes” in step S50), the first setting unit 31 sets the value of the first setting flag in the setting information storage unit 22 to 1 (step S55).
The first setting unit 31 inquires of the user whether or not to automatically set the target group of the function via the display unit 4, and determines whether or not an instruction to automatically set is received from the user. (Step S60). When determining that an instruction to automatically set is received (“Yes” in step S60), the first setting unit 31 sets the value of the corresponding first flag to 1 for all groups in the address information table T100. Set (step S65).

When it is determined that an instruction to automatically set is not received, that is, an instruction to not automatically set is received (“No” in step S60), the first setting unit 31 sets the first flag corresponding to each group. Is set based on a user instruction (step S70).
In addition, when the first setting unit 31 determines that an instruction not to set the erroneous mail transmission prevention function, that is, an instruction to disable the function is received according to an instruction from the user ("No" in step S50), The first setting unit 31 sets the value of the first setting flag in the setting information storage unit 22 to 0, and sets the value of the corresponding first flag to 0 for all the groups in the address information table T100 ( Step S75).

(3) Destination Display Function Setting Processing Here, destination display function setting processing will be described using the flowchart shown in FIG.
The second setting unit 32 determines whether an instruction for setting the destination display function has been received in accordance with an instruction from the user (step S100).
If it is determined that it has been accepted (“Yes” in step S100), the second setting unit 32 sets the value of the second setting flag in the setting information storage unit 22 to 1 (step S105).

    The second setting unit 32 inquires of the user whether or not to automatically set the target group of the function via the display unit 4, and determines whether or not an instruction to automatically set is received from the user. (Step S110). When determining that an instruction to automatically set is received (“Yes” in step S110), the second setting unit 32 sets the value of the corresponding second flag to 1 for all the groups in the address information table T100. Setting is made (step S115).

When it is determined that an instruction to automatically set is not received, that is, an instruction to not automatically set is received (“No” in step S110), the second setting unit 32 sets a second flag corresponding to each group. Is set based on a user instruction (step S120).
In addition, when the second setting unit 32 determines that an instruction not to set the destination display function, that is, an instruction to disable the function is received according to an instruction from the user (“No” in step S100), the second setting unit 32 The setting unit 32 sets the value of the second setting flag in the setting information storage unit 22 to 0, and sets the value of the corresponding second flag to 0 for all the groups in the address information table T100 (step S125). ).

(4) Mail transmission process Here, the operation | movement which concerns on the mail transmission process is demonstrated using the flowchart shown in FIG.
The mobile phone 1 creates a mail by a character input operation by the user (step S150).

While creating a mail, that is, in a mail text ready state, the transmission processing unit 40 determines whether or not the send button B100 shown in FIG. 3 has been pressed. Or 2 clicks (step S155).
If it is determined that the operation is a one-click operation (“Yes (one click)” in step S155), the transmission processing unit 40 sends a mail based on the value of the first setting flag stored in the setting information storage unit 22. It is determined whether or not the erroneous transmission prevention function is effective (step S160).

If it is determined that the erroneous mail transmission prevention function is valid (“Yes” in step S160), the transmission processing unit 40 further sets a corresponding first flag among one or more mail addresses that are mail destinations. It is determined whether a mail address having a value of 1 exists (step S165).
When it is determined that the destination includes an email address whose first flag value is 1 (“Yes” in step S165), the transmission processing unit 40 invalidates the accepted operation (operation in which the transmission button B100 is clicked once). And the operation returns to step S150.

If it is determined that the transmission destination includes an email address with the value of the first flag being 1 (“Yes” in step S165), the transmission processing unit 40 validates the accepted operation (operation in which the transmission button B100 is clicked once). The operation is specified, and the display processing unit 41 determines whether the destination display function is valid based on the value of the second setting flag (step S170).
When the destination display function is set, that is, when it is determined that the value of the second setting flag is 1 (“Yes” in step S170), the display processing unit 41 displays one or more mails that are mail destinations. It is determined whether or not there is a mail address having a corresponding second flag value of 1 (step S175).

When it is determined that there is an e-mail address with the second flag value of 1 (“Yes” in step S175), the display processing unit 41 sets the e-mail address with the second flag value of 1 among the e-mail addresses to be transmitted. The address is displayed on the display unit 4 (step S180).
The display processing unit 41 determines whether or not a destination change instruction indicating that the mail address is to be changed is received from the user while the mail address is being displayed (step S185).

If it is determined that a destination change instruction has been received (“Yes” in step S185), the display processing unit 41 outputs a non-permission instruction to the transmission processing unit 40, and the transmission processing unit 40 does not transmit mail, The process returns to S150 and waits for an instruction from the user while keeping the screen during mail creation.
If it is determined that a destination confirmation instruction has been received (“No” in step S185), the display processing unit 41 outputs a permission instruction to the transmission processing unit 40, and the transmission processing unit 40 transmits mail (step S190).

  When it is determined that the operation of pressing the send button B100 is a two-click operation (“Yes (two clicks)” in step S155), and when it is determined that the erroneous mail transmission prevention function is not valid, that is, invalid ( In “No” in step S160), the process proceeds to step S170. Since subsequent operations have been described above, a description thereof will be omitted.

If it is determined that the send button B100 has not been pressed (“No” in step S155), the process returns to step S150.
In addition, when it is determined that the destination display function setting is not valid, that is, invalid (“No” in step S170), and there is a mail address whose second flag value is 1 among the destination mail addresses. If it is determined (“No” in step S175), the process proceeds to step S190. Since subsequent operations have been described above, a description thereof will be omitted.

1.4 Specific Example Here, the operation of the mobile phone 1 will be described using a specific example. Further, description will be made using the address information table T100 of FIG. 4 as necessary.

In this case, “A mountain ○ male” is input as the mail destination, and the value of the first flag corresponding to the mail address of this person is “1” as shown in FIG.
For this reason, when the erroneous mail transmission prevention function is enabled, even if the transmission button B100 is pressed (one click), no mail is transmitted and the creation screen remains unchanged.
(2) When Destination Display Function is Valid FIG. 10 is a specific example when a mail transmission instruction is accepted when the destination display function is valid. Since “A mountain ○ male” is input as the destination and the value of the first flag corresponding to the mail address of this person is “1” as shown in FIG. If the function is valid, an instruction to send an email is accepted by clicking the send button B100 twice, and if the function for preventing erroneous email transmission is not valid, clicking the send button B100 once.

In this case, since the value of the second flag corresponding to the mail destination is “1”, the destination list D110 including the mail addresses to be displayed is displayed after receiving the mail transmission instruction.
When a send button B110 included in the destination list D110 is pressed by a user operation, it is determined that a destination confirmation instruction has been accepted, and an email is transmitted. When the cancel button B111 is pressed, it is determined that an address change instruction has been accepted, and the screen returns to the mail creation screen.

(3) Other screen display Here, the screen when setting the erroneous mail transmission prevention function and the screen when setting the destination display function will be described using an example.
(3-1) Screen when Setting E-mail Missent Prevention Function FIG. 11 shows an example of a screen when setting the e-mail wrong sending preventing function. When the function is set, a first setting screen D120 that prompts a setting instruction is displayed.

  When the button B120 is pressed by a user operation in displaying the first setting screen D120, the second setting screen prompts an instruction as to whether or not to automatically set a group to be a target of the function as shown in the figure below. D130 is displayed. Thereafter, when the button B130 is pressed by a user operation, the value of the first flag is set to 1 for all groups.
