Abstract

Disclosed is a terminal apparatus including a communication unit which performs a wireless communication with another terminal apparatus and a determination unit which determines whether a terminal apparatus which is a sub terminal into, which data subject to copying is to be copied, exists through the communication via the communication unit, the terminal apparatus which is the sub terminal being a terminal apparatus to which the data is not yet transmitted, if the terminal apparatus is a main terminal from which the data is copied. Further including a control unit which reads out the data from a storage unit and transmits the data to the terminal apparatus which is the sub terminal determined to exist via the communication unit if the determination unit determines that the terminal apparatus which is the sub terminal exists.

Claims

1. A terminal apparatus, comprising:

a communication unit which performs a wireless communication with another terminal apparatus;

a determination unit which determines whether a terminal apparatus which is a sub terminal, into which data subject to copying is to be copied, exists through the communication via the communication unit, the terminal apparatus which is the sub terminal being a terminal apparatus to which the data is not yet transmitted, if the terminal apparatus is a main terminal from which the data is copied; and

a control unit which reads out the data from a storage unit and transmits the data to the terminal apparatus which is the sub terminal determined to exist via the communication unit if the determination unit determines that the terminal apparatus which is the sub terminal exists,

wherein

processing from determining of existence of the terminal apparatus which is the sub terminal by the determination unit to transmitting of the data by the control unit is repeatedly performed.

2. The terminal apparatus as claimed in claim 1, wherein

if the terminal apparatus is the sub terminal, the control unit receives the data from a terminal apparatus which is the main terminal via the communication unit and stored the data in the storage unit.

3. The terminal apparatus as claimed in claim 2, wherein

if the terminal apparatus is the sub terminal, the control unit sets the terminal apparatus so as to act as the main terminal after storing the data received from the terminal apparatus which is the main terminal in the storage unit.

4. The terminal apparatus as claimed in claim 3 further comprising:

a first operating unit which receives an input of setting information to make the terminal apparatus act as the main terminal, wherein

if the terminal apparatus is the sub terminal, the control unit determines whether the setting information is input to the first operating unit and makes the terminal apparatus act as the main terminal if the setting information is input, after storing the data received from the terminal apparatus which is the main terminal in the storage unit.

5. The terminal apparatus as claimed in claim 1 further comprising:

a second operating unit which receives an input of information indicating whether the terminal apparatus is the main terminal or the sub terminal, wherein

the control unit determines whether the terminal apparatus is the main terminal or the sub terminal according to the information input to the second operating unit.

6. The terminal apparatus as claimed in claim 1, wherein

if the terminal apparatus is the main terminal, the determination unit determines whether a terminal apparatus which is the sub terminal having a predetermined tentative terminal name for the sub terminal exists through the communication via the communication unit, and

if the terminal apparatus is the sub terminal, the control unit changes a terminal name of the terminal apparatus to the tentative terminal name for the sub terminal.

7. The terminal apparatus as claimed in claim 1, wherein

at least one group to which the terminal apparatus belongs is set,

if the terminal apparatus is the main terminal, the determination unit determines whether a terminal apparatus which is the sub terminal having a tentative terminal name relating to a group to which the terminal apparatus belongs exist through the communication via the communication unit, and

if the terminal apparatus is the sub terminal, the control unit changes a terminal name of the terminal apparatus to the tentative terminal name relating to the group to which the terminal apparatus belongs.

8. The terminal apparatus as claimed in claim 7 further comprising:

a third operating unit which receives an input of identification information of the group to which the terminal apparatus belongs, wherein

if the terminal apparatus is the main terminal, the determination unit determines whether a terminal apparatus which is the sub terminal having a tentative terminal name relating to the group corresponding to the identification information input to the third operating unit exist through the communication via the communication unit, and

if the terminal apparatus is the sub terminal, the control unit changes the terminal name of the terminal apparatus to the tentative terminal name relating to the group corresponding to the identification information input to the third operating unit.

9. The terminal apparatus as claimed in claim 6, wherein

if the terminal apparatus is the sub terminal, the control unit changes the terminal name of the terminal apparatus to the tentative terminal name and stores the terminal name before the change in the storage unit, and the control unit resets the terminal name of the terminal apparatus to the terminal name before the change stored in the storage unit after the data is received.

10. The terminal apparatus as claimed in claim 1, wherein

if the terminal apparatus is the main terminal, the control unit starts pairing with the terminal apparatus which is the sub terminal determined to exist via the communication unit and transmits the read data to the terminal apparatus which is the sub terminal, and

if the terminal apparatus is the sub terminal, the control unit starts pairing with a terminal apparatus which is the main terminal via the communication unit and receives the data from the terminal apparatus which is the main terminal.

11. The terminal apparatus as claimed in claim 10, wherein

if the terminal apparatus is the main terminal, the control unit sets a communication mode of the communication unit to a stealth mode, and

if the terminal apparatus is the sub terminal, the control unit set the communication mode of the communication unit to the stealth mode when the pairing with the terminal apparatus which is the main terminal is started.

12. The terminal apparatus as claimed in claim 1, wherein

if the terminal apparatus is the main terminal, the control unit calculates a checksum of the read data and transmits the data and the calculated checksum to the terminal apparatus which is the sub terminal determined to exist, and

if the terminal apparatus is the sub terminal, the control unit receives the data and the checksum from a terminal apparatus which is the main terminal, calculates a checksum of the received data, compares the received checksum to the calculated checksum and waits for data and a checksum to be transmitted again from the terminal apparatus which is the main terminal if the checksums do not match.

13. The terminal apparatus as claimed in claim 1, wherein the communication unit uses a Bluetooth (registered trademark) format for the communication.

14. A non-transitory computer readable medium which stores a program for making a computer execute a process, the process comprising:

performing a wireless communication between one terminal apparatus and another terminal apparatus;

if the one terminal apparatus is a main terminal from which data is copied, determining whether a terminal apparatus which is a sub terminal into which the data subject to copying is to be copied exist through the communication with the second terminal apparatus, the terminal apparatus which is the sub terminal being a terminal apparatus to which the data is not yet transmitted;

if the terminal apparatus which is the sub terminal is determined to exist, reading the data from a storage unit and transmitting the data to the terminal apparatus which is the sub terminal determined to exist, and

repeatedly performing processing from the determining whether the terminal apparatus which is the sub terminal exists to the transmitting of the data.
