When the communication unit 35 receives a data read request signal, the control unit 31 receives the requested data. The entire external storage device 3 (3a to 3c) is comprehensively controlled, such as a process of reading out from the memory 32 and outputting to the communication unit 35.

  The operation unit 33 receives various operation inputs from the user. The display unit 34 displays various data such as input data input from the operation unit 33 or data transmitted / received via the communication unit 35 on the screen.

  The external storage device 3 (3a to 3c) is movable, and can be mounted on, for example, a mobile phone or a wristwatch owned by each user.

  Next, the operation of the radio communication system according to the present embodiment configured as described above will be described. FIG. 3 is a flowchart showing a processing operation when data desired by the user of the personal computer 1 is transmitted to the external storage device 3.

  First, the user of the personal computer 1 starts an application for using simple wireless communication (step ST1). Next, simple wireless communication is performed by processing of the application to search for the external storage device 3 that exists in the vicinity of the personal computer 1, and the external storage device 3 that is searched, that is, the external storage device 3 that can communicate with the personal computer 1 at the present time. Is displayed on the display screen of the personal computer 1 (step ST2). As a result, for example, as shown in FIG. 5, the external storage devices 3a, 3b, and 3c are displayed as a list.

  Then, the user selects the desired external storage device 3 (3a to 3c) by looking at this display screen (step ST3). For example, when there are three external storage devices 3 (3a to 3c) as shown in FIG. 5, one of the external storage devices 3 is selected.

  After that, the user selects data to be transmitted on the personal computer 1 and presses the “Ctrl + C” key that is a copy command to copy, and the cut command “Ctrl” to cut. The "+ X" key is pressed (step ST4). Alternatively, a copy or cut command is input using an input means such as a mouse.

  Next, the simple communication module 11 of the personal computer 1 reads the selected copy data or cut data from the memory 12, and transmits this data to the selected external storage device 3 by simple wireless communication (step ST5). In the external storage device 3, the data transmitted from the personal computer 1 is received by the communication unit 35, and the received data is stored in the memory 32 (step ST6).

  In this way, the data transmitted from the personal computer 1 is stored and saved in the memory 32 in the external storage device 3.

  Next, with reference to a flowchart shown in FIG. 4, a processing procedure when data stored and saved in the external storage device 3 is transmitted to the personal computer 2 and pasted into a predetermined file will be described.

  First, the user of the personal computer 2 starts an application for using simple wireless communication (step ST11). Next, simple wireless communication is performed by processing of the application to search the external storage device 3 existing in the vicinity of the personal computer 2, and the external storage device 3 that is searched, that is, the external storage device 3 that can communicate with the personal computer 2 at the present time Is displayed on the display screen of the personal computer 2 (step ST12). As a result, for example, the external storage devices 3a, 3b, 3c are displayed as a list as shown in FIG.

  Then, the user looks at this display screen and selects one in which desired data is stored from the external storage devices 3 displayed as a list (step ST13). For example, when there are three external storage devices 3a to 3c as shown in FIG. 5, the external storage device 3 in which desired data is written is selected from these.

  Thereafter, the user presses the “Ctrl + V” key, which is a pasting command, on the personal computer 2 (step ST14). Alternatively, a pasting command is input using an input means such as a mouse. Then, when a paste command is input by the user of the personal computer 2, all data stored in the memory 32 of the external storage device 3 is read by application processing, and a list of these data is displayed on the display screen of the personal computer 2. (Step ST15). As a result, as shown in FIG. 6, for example, a list of data stored in the external storage device 3 such as characters or URL addresses is displayed.

  Then, when the user of the personal computer 2 selects the desired data by viewing this list display (step ST16), the selected data is pasted into the desired file of the personal computer 2 (step ST17). In this way, data transmitted from the personal computer 1 can be received by the personal computer 2 and this data can be pasted into a desired file.

  As described above, in the wireless communication system 100 according to the present embodiment, data transmission is performed between the personal computer 1 serving as the data transmission source and the personal computer 2 serving as the data transmission destination using simple wireless communication such as Bluetooth. Since data can be transmitted from the personal computer 1 to the personal computer 2 via the external storage device 3 (3a to 3c) through the possible external storage device 3 (3a to 3c), the personal computer 1 and the personal computer 2 Can be easily copied and pasted from the personal computer 1 to the personal computer 2, so-called “copy and paste” processing. Further, even when the personal computer 1 and the personal computer 2 are not turned on at the same time, copy and paste processing from the personal computer 1 to the personal computer 2 can be performed.

  In addition, unlike the prior art, there is no manual operation for the user to write down or store the data to be copied, so that an input error can be prevented. Furthermore, since the external storage device 3 can be moved, for example, even when the personal computer 1 and the personal computer 2 are installed at positions separated from each other, data transfer can be performed smoothly by moving the external storage device 3. be able to.

  Further, if the mobile phone or wristwatch possessed by the user has a simple wireless communication function and a data storage function, and the mobile phone or wristwatch is used as the external storage device 3, it is convenient to carry and easy to carry. Copy and paste processing can be performed. Further, the mobile phone itself as the external storage device 3 has the function of the receiving terminal, and the data copied by the personal computer 1 as the transmitting terminal is directly pasted into the address book of the mobile phone itself. Is also possible. On the other hand, the mobile phone itself has the function of the transmission side terminal, and the data written in the address book of the mobile phone is copied and transmitted to the personal computer 2 as the reception side terminal. It is also possible to do.

  In addition, since the data stored in the external storage device 3 can be used not only by the personal computers 1 and 2 but also by a plurality of other personal computers, data can be shared and data distribution can be simplified. I can expect.

  In the above-described embodiment, the case where the personal computer 1 is the data transmission side and the personal computer 2 is the data reception side has been described as an example. However, these may be reversed. Further, although two personal computers 1 and 2 are shown as terminals, it goes without saying that the same processing is possible even when three or more personal computers are provided.

  In the above-described embodiment, an example in which three external storage devices 3 (3a to 3c) are provided as the external storage device 3 has been described. However, the present invention is not limited to three.

  Furthermore, in the above-described embodiment, an example in which Bluetooth (trademark) is used as simple wireless communication has been described. However, the present invention is not limited to this, and other wireless communication can also be used.
