[Prior art]
2. Description of the Related Art In recent years, a mobile phone has a built-in camera, and can store a photographed image file and a music file typified by a ringtone melody or MP3 downloaded from a server in a built-in memory. The files that can be handled are still image files, moving image files, audio files, music files, and the like. These files have functions of viewing, editing, and deleting these files. In addition, an electronic mail function is also provided, and each file can be attached to a mail, and can be transmitted as an attached file to another information terminal equipped with a mail function.
[0003]
Further, Patent Document 1 predicts a state in which the storage capacity of a retransmission file (a file in which transmitted image information is sequentially stored in preparation for subsequent use (retransmission and transfer)) in a facsimile mail system is insufficient. Sometimes, a facsimile mail system including means for sequentially erasing the image information in the resent file in the oldest order at the time of writing to the resent file is described.

[Problems to be solved by the invention]
However, the capacity of the memory built in these mobile phones is not large due to the cost and the structural restrictions of the mobile phone. When storing image data and music data having a relatively large file size, the memory becomes full immediately. Become. Therefore, it was necessary to delete unnecessary files appropriately.
However, image files and music files shot with the built-in camera are often desired to be stored for a long period of time, so rather than deleting these files, transfer them to another information device such as a personal computer to free up space in the built-in memory. Had to be made.
[0006]
In such a case, the file to be transferred can be attached to the e-mail using the e-mail function and then transferred to another information device. There is no space left. In order to make space in the internal memory, it was necessary to select a file that had been transmitted after the e-mail was sent from a list of files in the internal memory and delete the selected file.
If a large number of files are to be transferred, this operation must be repeated for the number of files, which is very complicated and time-consuming.
[0007]
[Means for Solving the Problems]
In order to solve these problems, according to the present invention, when a desired file is attached to an e-mail and transmitted to another information terminal, the file attached to the transmitted e-mail is deleted from the storage unit due to the e-mail transmission. It was decided to.
This eliminates the need for the user to create a free space in the internal memory when transferring a file to be stored for a long time to another information device such as a personal computer.

The form is shown and corresponds to Claims 3 and 6, respectively.
[0009]
In FIG. 1, reference numeral 100 denotes a mobile phone, 10 denotes a control unit, 20 denotes a storage unit for storing various files, 30 denotes display of images taken by a camera and text of an e-mail, instructions of various operations, operation states of the mobile phone, and the like. Display section to display. Reference numeral 40 denotes an operation unit for giving various instructions to the mobile phone and creating e-mail, and 50 denotes a wireless communication unit for exchanging various data with the outside. Reference numeral 60 denotes transmission / reception data, and reference numeral 70 denotes a transmission / reception antenna for transmitting / receiving data to / from an external information terminal. In the present invention, the control unit 10 controls the operation of displaying characters and images on the display unit 30, transmitting and receiving data 60 to and from the external information terminal of the wireless communication unit 50 and storing various files in the storage unit 20. , And controls the entire operation of the mobile phone 100.
[0010]
The operation of the first embodiment of the present invention will be described with reference to the flowchart shown in FIG. When the user of the mobile phone 100 turns on the power (step a010), the control unit 10 enters a mail creation standby state in step a020. The user creates a mail text while viewing the display unit 30 using the operation unit 40, and when the creation of the mail is completed, the operation unit 40 notifies the control unit 10 that the creation of the mail is completed. Here, the “mail body” refers to a text file containing a sentence created by the user. The control unit 10 proceeds to step a030 and determines whether or not a file is attached. When a file is attached, the control unit 10 selects the file to be attached from the storage unit 20 and sets a flag d indicating deletion to the file (step a040). Further, the file data is transferred to the wireless communication unit 50, converted into a format that can be attached to an e-mail, and becomes an attached file. The control unit 10 controls the wireless communication unit 50 to transmit the mail together with the attached file according to the user's mail transmission instruction, and the transmission / reception data 60 is transmitted (step a050). When the transmission of the mail is completed, the wireless communication unit 50 sends a transmission completion notification to the control unit 10, and the control unit 10 acquires the transmission completion notification (step a060). Here, the control unit 10 further checks whether the file attached to the mail stored in the storage unit 20 has the flag d (step a070). If the flag is set, the storage unit 20 deletes the file from the storage unit 20. After the deletion (step a080), a message notifying that the mail transmission has been completed is displayed on the display unit 30 (for example, a character display of "mail has been sent!") (Step a090). Complete. On the other hand, if no file is attached in step a030, the processing is executed skipping steps a040 and a080, and the mail transmission operation is completed without deleting the file in the memory. The operation of deleting the attached file may be performed immediately after the e-mail transmission in step a050, or may be performed by setting a period such as deleting the file by the next day.
[0011]
FIG. 3 is a flowchart showing a second embodiment of the present invention, in which whether or not the same file as the attached file in the memory is deleted can be selected for each mail transmission. In a step (step b040) following the file attaching step (step b030), the operation unit 40 instructs whether to delete the file after sending the mail. In response to this instruction, the control unit 10 sets a flag d indicating deletion in the file corresponding to the deletion. Subsequent processing is the same as in the first embodiment of the present invention shown in FIG. By using the second embodiment, it is possible for a user to transfer as a file attached to a file that the user wants to transfer for use on another information terminal but does not want to delete from the internal memory of the mobile phone. it can. In the case of the present embodiment, in consideration of the convenience of the user, for the files for which attachment file deletion was not selected (files that were not deleted), the files that were transmitted when the file was browsed separately It is also conceivable to display a mark on the display unit indicating that.
[0012]
FIG. 4 is a flowchart showing a third embodiment of the present invention, in which deletion of a mail text can be set for a mail with a file attached. When the user attaches a file (step c030), the control unit 10 sets a flag d for the file as in the processing in the first embodiment (step c040). Next, the user sets whether or not to delete the mail body by using the operation unit 40 (step c050), and when the user selects to delete, sets a flag e indicating deletion of the mail in the mail body to be deleted in step c060. . After the mail transmission (step c070), it is checked in step c080 whether or not the post-transmission completion notification acquisition flag d is present (step c090). If the flag d is set, the file is deleted from the storage unit 20 (step c100). . Further, it is confirmed whether or not there is a flag e (step c110). If the flag e is set, the mail text is also deleted (step c120). Finally, transmission completion is displayed (step c130), and the mail transmission operation is completed.
[0013]
In the third embodiment, the mail text is deleted, but the transmission history of the mail is not deleted. This is because if the user has forgotten the destination of the file or if the user knows the destination but forgets the file name of the transferred file, the destination and the date and time recorded in the transmission history will be displayed. This is because the file can be searched for a hint. In addition to the operation of deleting the text of the mail immediately after the step of deleting the file in the memory in step c100, the period may be set such that the mail is deleted by the next day. In addition, a method of deleting only the mail text without deleting the attached file or a method of deleting the mail text even when there is no attached file can be considered.
[0014]
In addition to the above-described embodiment, an embodiment in which file deletion in the built-in memory can be set to be deleted after an arbitrary time, not immediately after sending an e-mail, is also considered.
[0015]
【The invention's effect】
As described above, according to the present invention, in order to increase the free space of the built-in memory, a user can transfer a file to be stored for a long period of time to a file stored in the built-in memory when transferred to another information device such as a personal computer. The work to delete is no longer required.
