Abstract

While the backlight is lit, if the control unit detects key input concerning a request instruction from a user by the request instruction signal from the operation unit, the control unit outputs the lights-out instruction signal to the display lighting unit to turn off the backlight, and outputs the detected request instruction signal to the communication unit. The communication unit transmits the request instruction signal to the server via the base station. If the server responses the request instruction signal and distributes the contents information to the communication unit via the base station, and the communication unit outputs the contents information within the waiting time, the control unit reproduces the contents information, outputs the reproduced contents information to the display unit to display the contents information on the display panel in the display unit, and outputs the light-up instruction signal to the display lighting unit to turn on the backlight.

Claims

1. A portable telephone device which receives contents information distributed from a server in response to a request made by a user for the contents information, the portable telephone device comprising:

a display panel which displays the received contents information thereon;

a backlight which lights up the display panel;

request detecting means for detecting that the request has been made; and

lighting control means for (a) turning off the backlight when the request detecting means detects that the request has been made and (b) turning on the backlight after the contents information is received.

2. The portable telephone device of claim 1, wherein

the lighting control means turns on the backlight when the lighting control means detects completion of a display procedure for displaying the received contents information on the display panel.

3. The portable telephone device of claim 2, wherein

the display procedure displays a portion of the received contents information on the display panel.

4. The portable telephone device of claim 3, wherein

the request detecting means includes an instruction accepting unit for accepting from the user an instruction for requesting the contents information, and detects that the request has been made by detecting the instruction.

5. The portable telephone device of claim 4, wherein

the lighting control means includes reception judgement means for judging whether the contents information is received within a predetermined period of time since the request detecting means detects that the request has been made, and

in the case where the reception judgement means judges that the contents information is not received within the predetermined period of time, the lighting control means displays on the display panel a message that the contents information failed to be received and turns on the backlight.

6. The portable telephone device of claim 3, wherein

the request detecting means includes an instruction accepting unit for accepting from the user an instruction for requesting the contents information, and detects that the request has been made by detecting transmission of the instruction.

7. The portable telephone device of claim 6, wherein

the lighting control means includes reception judgement means for judging whether the contents information is received within a predetermined period of time since the request detecting means detects that the request has been made, and

in the case where the reception judgement means judges that the contents information is not received within the predetermined period of time, the lighting control means displays on the display panel a message that the contents information failed to be received and turns on the backlight.

8. The portable telephone device of claim 2, wherein

the display procedure displays all of the received contents information on the display panel.

9. The portable telephone device of claim 8, wherein

the request detecting means includes an instruction accepting unit for accepting from the user an instruction for requesting the contents information, and detects that the request has been made by detecting the instruction.

10. The portable telephone device of claim 9, wherein

the lighting control means includes reception judgement means for judging whether the contents information is received within a predetermined period of time since the request detecting means detects that the request has been made, and

in the case where the reception judgement means judges that the contents information is not received within the predetermined period of time, the lighting control means displays on the display panel a message that the contents information failed to be received and turns on the backlight.

11. The portable telephone device of claim 8, wherein

the request detecting means includes an instruction accepting unit for accepting from the user an instruction for requesting the contents information, and detects that the request has been made by detecting transmission of the instruction.

12. The portable telephone device of claim 11, wherein

the lighting control means includes reception judgement means for judging whether the contents information is received within a predetermined period of time since the request detecting means detects that the request has been made, and
