Moreover, as exemplarily shown in
It should be noted that, in describing the following embodiments, the same reference numerals are assigned to the same constituents, and descriptions thereof are omitted or simplified.
An example of a first embodiment of the cellular telephone device 1 according to the present invention is hereinafter described.
“Creating a mail message” in the creating-and-editing part 31 refers to performing a new creation of, for example, a new mail message, a reply mail message, a forwarded mail message, and the like. Moreover, “editing a mail message” in the creating-and-editing part 31 refers, for example, to performing addition, deletion, modification, or the like to a new mail message already created by the creating-and-editing part 31, a received mail message, a reply mail message, an unsent mail message, a forwarded mail message, or the like.
Moreover, in a case in which a mail message associated with a received mail message that has been received by the receiving part 35 is not yet transmitted by the transmitting part 34, the control unit 38 controls such that the memory unit 33 stores the associated mail as an unsent mail message so as to be associated with the received mail message.
Here, the “associated mail” typically is a reply mail message in response to a received mail message or a forwarded mail message, and otherwise may be a single or a plurality of mail messages having a part of the mail addresses that is the destination, a part of the subject of the mail message, or a part of the mail message text that has a portion which overlaps that of a particular received mail message, unsent mail message, forwarded mail message, or the like. Moreover, a mail is also included which is individually associated by the user as an associated mail.
To “store the associated mail so as to be associated with the received mail message” indicates, for example, in a case of an associated mail message with a reply mail message or a forwarded mail message, mutually linking the reply mail message or the forwarded mail message with the original mail message and storing thereof in the unit 33. That is to say, while browsing a reply mail message or a forwarded mail message, a user can browse the original mail message with a simplified operation, and moreover, while browsing the original mail message, a user can browse the reply mail message or the forwarded mail message with a simplified operation.
Alternatively, this refers to extracting a mail message corresponding to the associated mail message using a sorting function of mail, mutually linking the extracted mail messages together, and storing thereof in the memory unit 33.
Moreover, when the received mail message is displayed on the display part 21, the control unit 38 controls such that the unsent mail associated with the received mail is read and displayed on the display part 21 in response to a predetermined operation by the operation unit 11. Alternatively, when the unsent mail is displayed on the display part 21, the control unit 38 controls such that the received mail associated with the unsent mail is read and displayed on the display part 21 in response to a predetermined operation by the operation unit 11.
To “read out an unsent mail message associated to a received mail message” refers, for example, to applying a sorting function of mail, extracting mail messages that correspond to mail messages associated with a received mail message based on the above-described mutual links, and reading out mail messages thus extracted. In addition, to “read out a received mail message associated with an unsent mail message” refers, for example, to applying a sorting function of mail, extracting mail messages that correspond to mail messages associated with an unsent mail message based on the above-described mutual links, and reading out mail messages thus extracted.
With such a configuration, when a received mail or an unsent mail message is displayed on the display part 21, the cellular telephone device 1 can display an unsent mail associated with the received mail or a received mail message associated with the unsent mail on the display part 21. Accordingly, the user can easily refer to an unsent mail message associated with the received mail, or a received mail message associated with the unsent mail.
Moreover, the control unit 38 may be configured to control such that an unsent mail message displayed on the display part 21 is edited by the creating-and-editing part 31 or deleted by the deleting part 37.
With such a configuration, the cellular telephone device 1 controls such that an unsent mail message displayed on the display part 21 is edited or deleted. Therefore, the user can edit or delete an unsent mail message while referring to a received mail associated with the unsent mail.
Moreover, the control unit 38 controls such that, when a received mail is displayed on the display part 21, an unsent mail message associated with the received mail is read and displayed on the display part 21 in response to a single operation (for example, a depressing operation on a direction key constituting the selection operation key 15) by way of the operation unit 11. Alternatively, the control unit 38 may be configured to control such that, when the unsent mail is displayed on the display part 21, received mail associated with the unsent mail is read and displayed on the display part 21 in response to a single operation by the operation unit 11.
With such a configuration, in response to a single operation by the operation unit 11, the cellular telephone device 1 can read out a mail message associated with the received mail, or received mail associated with the unsent mail from the memory unit 33 and display thereof on the display part 21. Therefore, the user can switch the display from a received mail to a mail message associated with the received mail message, or from an unsent mail message to a mail message associated with the unsent mail, by an easy operation.
Moreover, the control unit 38 may be configured to control such that, when an unsent mail message is transmitted by the transmitting part 34, or when the unsent mail message is deleted by the deleting part 37, a received mail message associated with the unsent mail message is displayed on the display part 21.
With such a configuration, when an unsent mail message is transmitted, or when the unsent mail message is deleted, the cellular telephone device 1 displays received mail associated with the unsent mail on the display part 21. Therefore, when an unsent mail is transmitted or deleted, the user can easily refer to a received mail associated with the unsent mail.
Moreover, the control unit 38 may be configured to control such that, in a case in which there are a plurality of unsent mail messages associated with a received mail, the unsent mail messages are preferentially read out in order of creation date and time or editing date and time of the unsent mail from new, the unsent mail messages are displayed on the display part 21.
To “preferentially read out” indicates, for example, to read out unsent mail messages in order of new creation data and time or editing data and time, according to an operation at the operation unit 11.
With such a configuration, in a case in which there are a plurality of unsent mail messages associated with a received mail, in the cellular telephone device 1 preferentially reads out the unsent mail messages in order of creation date and time or editing date and time thereof from new and displays the unsent mail message thus read out on the display part 21. Therefore, it is possible to display unsent mail messages in order of the creation date and time or editing date and time thereof from new, which priority is considered to be high for the user, on the display part 21.
Here, an example of operations of the control unit 38 is described, for a case in which there is a plurality of unsent mail messages associated with a received mail message, and the unsent mail messages are preferentially read. When the unsent mail messages are read, which have been stored in the memory unit 33 so as to be associated with a received mail message, the control unit 38 sorts the unsent mail messages thus read. Criteria for sorting are the latest date and time of creating the unsent mail messages, the latest date and time of editing the unsent mail messages, titles of the unsent mail messages, mail addresses of the unsent mail messages, and the like. The control unit 38 reads the unsent mail messages in the sorted order, and displays thereof on the display part 21.
Moreover, the control unit 38 may be configured to control such that, in a case in which there are a plurality of unsent mail messages associated with a received mail message, and one of the unsent mail messages displayed on the display part 21 is transmitted by the transmitting part 34 or deleted by the deleting part 37, the other unsent mail messages among the unsent mail messages are displayed on the display part 21.
With such a configuration, in a case in which one of the plurality of unsent mail messages is transmitted or deleted, the cellular telephone device 1 can display the other unsent mail messages among the unsent mail messages on the display part 21. Therefore, after completion of editing or deleting one of the unsent mail messages, the other unsent mail messages can be easily referred to.
Moreover, the control unit 38 may be configured to control such that the other unsent mail messages, which are displayed on the display part 21, are edited by the creating-and-editing part 31 or deleted by the deleting part 37.
With such a configuration, the cellular telephone device 1 can control such that the other unsent mail messages, which are displayed on the display part 21, are edited or deleted. Accordingly, the user can easily edit or delete the other unsent mail messages after completion of editing or deleting one of the plurality of unsent mail messages.
Here, there are cases in which predetermined data is attached as an attached file to forwarded mail messages or received mail messages associated with unsent mail messages. In this case, when an unsent mail message is displayed on the display part 21, the control unit 38 displays the predetermined data attached to the received mail message or the forwarded mail message on the display part 21 according to a simplified attached data display operation different from a predetermined operation by way of the operation unit 11.
More specifically, the control unit 38 displays image data attached to a received mail message according to an attached data display operation on the display part 21 in a case in which image data has been attached as predetermined data to a received mail message associated with the unsent mail message. It should be noted that, in the operation unit 11, a key that performs the attached data display operation is made to be an assigned key that is different from a key performing the predetermined operation.
“Predetermined data” indicates data attached to this mail message in a forwarded mail message or a received mail message associated with the unsent mail message. Predetermined data can be exemplified by image data, video data, text data, audio data, and the like. The number of sets of predetermined data is not particularly limited, but one or a plurality of sets of data are attached to a forwarded mail message or a received mail message associated with an unsent mail message.
With such a configuration, in a case in which an unsent mail message is displayed on the display part 21, the predetermined data attached to the received mail message or forwarded mail message can be referred to by an easy operation. Therefore, according to the cellular telephone device 1 of the present embodiment, it is possible to improve operability for a forwarded mail message or a received mail message associated with an unsent mail message.
Next, an example of a second embodiment of the cellular telephone device 1 according to the present invention is described. The cellular telephone device 1 according to the second embodiment is hereinafter described mainly with points that differ from the cellular telephone device 1 according to the first embodiment, and the other descriptions are omitted.
In the second embodiment, in a case in which a plurality of mail messages associated with a received mail message, which was received by the receiving part 35, have not yet transmitted by the transmitting part 34, the memory unit 33 stores the plurality of associated mail messages as an unsent mail group so as to be associated with the received mail message.
“Stores as an unsent mail group” indicates that, for example, a plurality of associated mail messages are associated with a received mail message, and stored in one folder.
Moreover, when one unsent mail message in the unsent mail group is displayed on the display part 21, and a predetermined operation is performed by the operation unit 11, the control unit 38 controls such that the other unsent mail messages in the unsent mail group are read and displayed on the display part 21.
With such a configuration, in, when one unsent mail message in the unsent mail group is displayed on the display part 21, and a predetermined operation is performed by the operation unit 11, the cellular telephone device 1 reads the other unsent mail messages in the unsent mail group, and displays thereof on the display part 21. Therefore, the user can easily refer to the other unsent mail messages associated with the one unsent mail message.
Moreover, the control unit 38 may be configured to control such that the other unsent mail messages, which are displayed on the display part 21, are edited by the creating-and-editing part 31 or deleted by the deleting part 37.
With such a configuration, the cellular telephone device 1 can edit or delete the other unsent mail messages in the unsent mail group that are displayed on the display part 21. Therefore, the user can edit or delete the other unsent mail messages while referring to one unsent mail message.
Moreover, the control unit 38 may be configured to control such that, when one unsent mail message is displayed on the display part 21, the other unsent mail messages are read and displayed on the display part 21 in response to a single operation (for example, a depression operation of the direction key constituting the selection operation key 15) by the operation unit 11.
With such a configuration, when one unsent mail message is displayed on the display part 21, the cellular telephone device 1 reads out the other unsent mail messages in response to a single operation by the operation unit 11, and displays thereof on the display part 21. Therefore, the user can switch displaying from one unsent mail message to the other unsent mail messages by performing an easy operation.
Moreover, the control unit 38 may be configured to control such that, when one unsent mail message is displayed on the display part 21, the other unsent mail messages are read and displayed on the display part 21 in response to a single operation by the operation unit 11, and when the other unsent mail messages are transmitted by the transmitting part 34 or the other unsent mail messages are deleted by the deleting part 37, the one unsent mail message is displayed on the display part 21.
With such a configuration, when one unsent mail message is displayed on the display part 21, the cellular telephone device 1 reads out the other unsent mail messages in response to a single operation by way of the operation unit 11, and displays thereof on the display part 21. Moreover, when the other unsent mail messages are transmitted or deleted, the one unsent mail message, which had been displayed on the display part 21 before performing the single operation by way of the operation unit 11, is displayed on the display part 21. Therefore, the user can easily refer to the one unsent mail message associated with the other unsent mail messages after transmitting or deleting the other unsent mail messages.
Moreover, the control unit 38 may be configured to control such that, in a case in which there is a plurality of the other unsent mail messages, the unsent mail messages are preferentially read out in order of creation date and time or editing date and time of the unsent mail messages from new, and the unsent messages are displayed on the display part 21.
With such a configuration, in a case in which there are a plurality of other unsent mail messages associated with one unsent mail message, the cellular telephone device 1 preferentially reads out the unsent mail messages in order of creation date and time or editing date and time of the unsent mail messages from new, and displays thereof on the display part 21. Therefore, it is possible to display the other unsent mail messages in order of creation date and time or editing date and time thereof from new, for which the priority for the user is considered to be high, on the display part 21.
Moreover, the control unit 38 may be configured to control such that, in a case in which there are a plurality of other unsent mail messages, and one of the unsent mail messages among thereof is displayed on the display part 21, and in a case in which the one unsent mail message that is displayed on the display part 21 is transmitted by the transmitting part 34 or deleted by the deleting part 37, the other unsent mail messages, which are not displayed on the display part 21, are then displayed on the display part 21.
With such a configuration, in the cellular telephone device 1, in a case in which there is a plurality of other unsent mail messages associated with one unsent mail message, one of the unsent mail messages among thereof is displayed on the display part 21, and the one unsent mail message displayed is transmitted or deleted, the other unsent mail messages, which are not displayed, are then displayed on the display part 21. Therefore, the user can easily refer to the other unsent mail messages after transmitting or deleting one unsent mail message.
Moreover, the control unit 38 may be configured to control such that the other unsent mail messages, which are displayed on the display part 21, are edited by the creating-and-editing part 31 or deleted by the deleting part 37.
With such a configuration, the cellular telephone device 1 controls such that the other unsent mail messages, which are associated with one unsent mail message displayed on the display part 21, are edited or deleted. Therefore, after completion of editing or deleting one unsent mail message among the plurality of other unsent mail messages, the user can easily edit or delete the other unsent mail messages.
Here, an example of changing an appearance of a mail message display screen that is displayed on the display part 21 of the cellular telephone device 1 according to the first and second embodiments is described with reference to
As shown in
When browsing a received mail message on the display screen L, the user depresses, for example, a right direction key (hereinafter referred to as the right direction key) constituting the selection operation key 15, as an example of the single operation. As a result, the display screen is switched to the display screen M, thereby making it possible to browse, edit or delete unsent mail messages associated with the received mail message. Here, when “edit” in a center of a lower end portion of the screen is selected, a submenu for editing is displayed, and by selecting “transmit,” “edit,” “delete” or the like from the submenu, the received mail messages or the unsent mail messages can be transmitted, edited, deleted or the like.
Moreover, while browsing or editing an unsent mail message on the display screen M, a left direction key (hereinafter referred to as the left direction key), for example, which constitutes the selection operation key 15, is depressed, as an example of the single operation. As a result, the display screen is switched to the display screen L, thereby making it possible to browse, edit or delete the received mail message associated with the unsent mail message. Then, by depressing the right direction key, the display screen is switched to the display screen R, thereby making it possible to browse, edit or delete the other unsent mail messages associated with the unsent mail message. It should be noted that, when editing of a received mail message is selected, an unsent mail message is created as a new associated mail message.
Moreover, while browsing or editing an unsent mail message on the display screen R, by depressing the left direction key, the display screen is switched to the display screen M, thereby making it possible to browse, edit or delete unsent mail messages associated with the other unsent mail messages. Therefore, by depressing the right direction key while browsing a received mail message, it is possible to display the latest unsent mail message among the associated mail messages associated with the received mail message. By depressing the right direction key again while displaying this unsent mail message, it is possible to display a new unsent mail message having an editing date and time that is the second latest to the latest unsent mail message among the associated mail messages. Alternatively, by depressing the left direction key while displaying this unsent mail message, it is possible to display the received mail again.
Moreover, by depressing the left direction key after displaying the unsent mail having an editing date and time that is the second latest to the latest unsent mail message, it is possible to display the latest unsent mail message again. Thereafter, by depressing the left direction key again while displaying this latest unsent mail message, it is possible to display the received mail message as described above.
In this way, in the relationship of display ranking among the received mail messages and the unsent mail message, it is possible to switch the display from the received mail message to the unsent mail message, which should have top priority, and vice versa, i.e. it is also possible to switch the display from the unsent mail which should have top priority to the received mail. Furthermore, unsent mail messages having adjacent priority rankings of display also can be switched between.
It should be noted that, although the control unit 38 controls such that the received mail messages associated with the unsent mail messages as well as the other unsent mail messages are stored in the memory unit 33 by performing association in the aforementioned embodiments, it is not limited thereto. For example, the control unit 38 controls such that the other received mail messages associated with the received mail messages are stored in the memory unit 33 by performing association. Moreover, when the received mail message is displayed on the display part 21, the control unit 38 controls such that the other received mail messages associated with the received mail message are read and displayed on the display part 21 in response to a predetermined operation by the operation unit 11. Alternatively, the control unit 38 may be configured to control such that, when the other received mail messages are displayed on the display part 21, a received mail message associated with the other received mail messages is read out in response to a predetermined operation by the operation unit 11, and the received mail message is displayed on the display part 21.
With such a configuration, when a received mail message is displayed on the display part 21, the cellular telephone device 1 can display the other received mail messages associated with the received mail message on the display unit 21. Therefore, the user can easily refer to the other received mail messages associated with the received mail message.
Although embodiments of the present invention have been described above, the present invention is not limited to the aforementioned embodiments. Moreover, the effects described in the embodiments of the present invention merely illustrate the most preferred effects arising from the present invention, and the effects according to the present invention are not limited to those described in the embodiments of the present invention.
It should be noted that, in the embodiments described above, although an example is described in which unsent mail messages and received mail messages are switched therebetween in regards to one example of a mail display screen that is displayed on the display part 21, the present invention is not limited thereto. For example, in a case where an unsent mail message is displayed on the display part 21, the control unit 38 may be configured so that a received mail message related to an unsent mail message is displayed as a pop-up on the display part 21. Similarly, in a case where a received mail message is displayed on the display part 21, the control unit 38 may be configured so that an unsent mail message related to a received mail message is displayed as a pop-up on the display part 21.
In this case, a position at which the pop-up is displayed on the display part 21 may a location where the pop-up is superimposed on an unsent mail message or a received mail message on the display part 21. Alternatively, a position at which the pop-up is displayed on the display part 21 may be within an area in which an unsent mail message or a received mail message is not displayed on the display part 21.
In addition, the control unit 38 causes a scroll bar to be displayed at a predetermined position of the pop-up display. Then, in a case where the pop-up is displayed on the display part 21, the control unit 38 may display information displayed in the pop-up to be scrolled by way of operating the scroll bar.
