  The present invention relates to a data transmission / reception apparatus that transmits and receives data, and a recording medium that stores a program for operating a computer as such a data transmission / reception apparatus.

  In recent years, mobile terminals have come to be used as small portable information devices. This includes a user schedule management function, a text editor function, and the like, and can store and store various data created by the user.

  Also known are those that have a connection function with a PHS telephone or a PHS telephone function itself, and can download various types of information by so-called Internet or personal computer communication. Furthermore, there are some that incorporate a digital camera connection function or a digital camera function itself.

  However, the mobile terminal as described above generally has a small data storage capacity and cannot store a large amount of data. Therefore, when saving downloaded information or image data taken with a digital camera, the user must pay attention to the free storage capacity, and if there is not enough free space, delete any other data. There was a need. Therefore, if there is only data that cannot be deleted later, it is impossible to store new data.

  An object of the present invention is to enable a user of a device having a limited data storage capacity, such as a mobile terminal, to create data without worrying about the data capacity.

  The present invention is a data transmission / reception apparatus connected to various terminals via a network, wherein a location name storage means for storing a plurality of location names in association with location information, and the network from a terminal of a data transmission source. When receiving the image data via the position name storage means, the position of the terminal of the transmission source is determined, and a position name corresponding to the position information of the determined position is searched from the position name storage means and specified, When storing the received image data, the image data is stored by assigning a location name specified by the specifying unit and stored by the data requesting terminal via the network. When the image data transmission request is received, the image data and the location name given to the image data are sent to the data requesting terminal. Characterized by comprising transmission means signals to, the.

  According to the present invention, when image data is transmitted from the transmission source terminal to the data transmission / reception apparatus, the data transmission / reception apparatus side determines the position of the transmission source and assigns a position name corresponding to the position to the image data. Automatically saved and saved, so when an arbitrary terminal requests and downloads the saved image data later, the image is referred to by referring to the location name given to the image data. You can immediately check the location when the data was sent.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.
[First Embodiment]
FIG. 1A is a block configuration diagram of a communication network system to which the data transmission / reception apparatus according to the first embodiment of the present invention is applied. The data transmission / reception apparatus according to the present embodiment is, for example, an Internet service provider. It is comprised as a server of the so-called provider 10 which is.

  The provider 10 is connected to a PHS base station 30 and a personal computer (PC) 40 via the communication line 20. The PHS base station 30 mediates data communication between the mobile terminal 50 having a PHS telephone function and a digital camera function and the communication line 20.

  FIG. 1B is a diagram showing a configuration of the server of the provider 10, and reference numeral 11 in the figure is a CPU as a control unit that controls the entire server. Reference numeral 12 denotes an input device such as a keyboard or a mouse, 13 denotes a display device such as a CRT, and 14 denotes a printing device such as a printer. Reference numeral 15 denotes a storage device such as a hard disk or a ROM, and reference numeral 16 denotes a RAM.

  Reference numeral 17 denotes a storage medium control unit for controlling data storage and reading with respect to a storage medium 18 such as a mounted floppy disk or optical (magnetic) disk, and 19 denotes the communication line 20. A communication control unit for sending and receiving data to and from the outside.

  The storage device 15 or the storage medium 18 is stored in advance with a processing program executed by the CPU 11 for operating as a data transmitting / receiving device, data, and the like. Alternatively, the program, data, and the like stored in the storage medium 18 are received by the communication control unit 19 from another device connected via the communication line 20 or the like (for example, stored in a work memory (not shown) provided in the RAM 16). Further, a configuration may be adopted in which a storage device or a storage medium is provided on the other device side connected via the communication line 20 or the like, and the program and data stored therein are used via the communication line 20. It may be.

  In the present embodiment, as shown in FIG. 2A, the storage device 15 is provided with a folder 15A for each user, that is, for each transmission source, and image data is stored in each transmission source folder 15A. An image folder 15A1 for storing and another folder 15A2 for storing other data are provided. Actual image data and its index data are stored in association with each other in the image folder 15A1, and similarly, data other than image data and its index data are stored in association with each other in the other folder 15A2.

Further, the storage device 15 also stores a registration table 15B and a place name table 15C as shown in FIG.
Here, the registration table 15B stores a registration address and a permission address in association with each other, and stores address data allocated to the PC 40, the mobile terminal 50, or the user, respectively. The registration address stores an address as a transmission source, and the permission address includes the PC 40 indicated by the corresponding registration address 15B1 or the PC 40 that may transmit data received from the mobile terminal 50 or the user. The mobile terminal 50 or the user's address is registered.

  For example, in order for the user of the mobile terminal 50 to be able to send the data created by the mobile terminal 50 to the PC 40 at the user's home, the mobile terminal 50 or the user's address as the registered address and the self-address as the permitted address. It is necessary to store the PC 40 and the user's address. In addition, in order to be able to transmit to another person's PC 40 such as a company, a business partner, or a friend, it is necessary to store the addresses of these other person's PCs 40 in a permitted address. The addresses are stored in the registration address and the permission address, for example, by specifying each address and the user applying for this service to the provider 10. Of course, it is allowed to associate a plurality of permitted addresses with one registered address.

  The place name table 15C stores position information and place names in association with each other. That is, the location information stores the address of the PHS base station 30, and the place name stores the PHS base station having the corresponding address, that is, the location name, address, facility name, etc. Yes.

Next, the operation in such a configuration will be described.
FIG. 3 is a flowchart for explaining the operation at the time of data reception in the server of the provider 10 to which the data transmitting / receiving apparatus according to the first embodiment is applied. A program for realizing each function described in this flowchart is stored in the storage device 15 or the storage medium 18 in the form of a program code readable by the CPU 11.

  First, when the communication control unit 19 receives data from the mobile terminal 50, the CPU 11 checks the address of the data transmission source (step S11). Then, the registration table 15B determines whether or not the transmission source address is stored as the registration address (step S12). If not, the communication control unit 19 returns a notification that the data reception is rejected to the data transmission source. (Step S13), the data receiving operation is terminated.

  On the other hand, if there is a registered address that matches the transmission source address, the CPU 11 next specifies a folder corresponding to the transmission source from among a plurality of transmission source folders 15A provided in the storage device 15 ( Step S14). Further, the location of the transmission source, that is, the PHS base station 30 used for communication is determined (step S15), and the place name (facility name) is searched with reference to the place name table 15C (step S16). Thereafter, the data type of the received data is determined (step S17), and if it is image data (step S18), the image folder 15A1 of the specified transmission source folder 15 is specified (step S19). Otherwise, the other folder 15A2 is specified (step S20).

  Then, the received data is stored in the identified folder 15A1 or 15A2 using the data type, place name, date and time as an index (step S21), and the communication control unit 19 notifies the transmission completion mobile terminal 50 of the saving. (Step S22), the data receiving operation is terminated.

FIG. 4 is a flowchart of the data transmission operation when a transmission request for the stored data is received.
That is, when the communication control unit 19 receives a data transmission request from the PC 40 or the mobile terminal 50, the CPU 11 first checks the request source address (step S31), and registers the permitted address that matches the request source address in the registration table. Search from 15B (step S32). When there is no matching address, that is, when the request source is not permitted (step S33), the communication control unit 19 notifies the request source of data transmission rejection (step S34), and this data transmission operation is performed. finish.

  On the other hand, if the request source is permitted, the CPU 11 next refers to the registration table 15B, specifies the source-specific folder 15A from the corresponding registration address (step S35), and is stored there. Although data is transmitted to the request source, in this embodiment, security is enhanced by performing password check instead of unconditionally transmitting data. That is, the CPU 11 receives the password from the request source by the communication control unit 19 (step S36), and when the regular password is not given (step S37), the CPU 11 proceeds to the step S34 to notify the data transmission rejection. .

  If the password check is OK, a list of data stored in the specified folder 15A is transmitted to the request source by the communication control unit 19 (step S38), and a selection instruction from the request source is awaited ( Step S39). When the selection instruction is received, the selection data, that is, the image data or other data itself and the corresponding index are transmitted to the request source by the communication control unit 19 ((Step S40), and this data transmission operation is performed. Exit.

  As described above, according to the first embodiment, a user of an information device having a limited data storage capacity such as the mobile terminal 50 can use the server of the provider 10 as a data transmission / reception device as a temporary storage location. Since it can be used, it becomes possible to create image data, that is, to shoot or download data from the Internet without worrying about the data capacity. In addition, since the server side automatically assigns the location name and the like, when the data is later downloaded by the PC 40 or the mobile terminal 50, it is immediately known where the data was created. Can do.

[Second Embodiment]
Next, a second embodiment of the present invention will be described.
In the second embodiment, the mobile terminal 50 is a digital camera having a PHS telephone function, which operates as a data transmission / reception device. The configuration of the digital camera with a PHS function as the data transmitting / receiving apparatus of the present embodiment is not particularly different from the conventional one, and the description thereof is omitted.

It is an operation | movement flowchart.

  That is, the CPU of the digital camera with a PHS function as a data transmission / reception device performs a well-known image photographing operation (step S51), stores the obtained image data in a storage medium (not shown), and adds an index such as a photographing date and time. (Step S52). Here, the CPU determines whether or not the number of image data has exceeded 10 (step S53). If not, the CPU returns to step S51 to enable further photographing.

  On the other hand, when the number of captured image data exceeds 10, the CPU transmits a data transmission request to the contract provider using the PHS telephone function (step S54).

  Thereafter, the image data is transmitted (step S55), an index image obtained by reducing the image data is generated (step S56), and the index image and the index of the transmitted image data are associated with each other and stored in the storage medium. (Step S57). Then, the transmitted image data is deleted (step S58).

  Here, it is determined whether or not the transmission of all the image data stored in the storage medium has been completed (step S59). If not, the next image data is designated (step S60), and the process returns to step S55. If all the image data has been transmitted, the transmission end is notified to the provider side (step S61), and this upload operation is terminated.

  When the server of the provider 10 receives the data transmission request in the steps 54 and 54 (step S71), it specifies the corresponding source-specific folder 15A from the source address as described in the first embodiment. (Step S72) The image data transmitted in Step S55 is stored together with the index sent together therewith or the index automatically generated as described in the first embodiment (Step S72). Step S73). The received image data storage process is repeated until the transmission end notification is given in step S61 (step S74).

In this way, the download of the image data stored in the server of the provider 10 is performed as shown in FIG.
That is, the CPU of the digital camera with a PHS function as the data transmitting / receiving apparatus reads the index image stored in the above step and 57 from the storage medium and displays it on a display unit (not shown) such as an LCD (step S81). When the user performs a predetermined image selection operation based on the index image (step S82), the index corresponding to the selected index image is specified (step S83), and a download request is transmitted to the contract provider (step S83). S84).

  If image data corresponding to the index is transmitted in response to the download request, it is received (step S85), stored in a storage medium (step S86), and the download operation is terminated. .

  As described above, according to the second embodiment, a user of an information device having a limited data storage capacity such as a mobile terminal can use a predetermined device as a temporary storage location. Thus, it is possible to perform shooting or the like without worrying about the image data capacity. In addition, since there is no need to designate the transmission destination of the captured image data one by one, the operation is simple.

  In the second embodiment, uploading is performed every time 10 images are taken, but it is needless to say that the number is not limited to this. Also, regardless of the number of shots, for example, it may be uploaded immediately at the stage of shooting, or when there is no shooting, that is, when the camera function is turned off, etc. You may make it upload.
