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.
