<p>PURPOSE:To evade the malfunctions due to the canceling action of an automatic power-off state by converting the input data corresponding to the first operation carried out in the automatic power-off state into the input data that are effective, to only the cancel of the automatic power-off state. CONSTITUTION:It is presumed that a display device 2 inputs first the data with an optional operation in a power supply stop state caused by an automatic power-off state, for example. Under such conditions, an operation input control part 8 converts the input data into the data that are effective to only the cancel of the power supply stop state of the device 2. A keyboard controller 7 transmits a power-on signal to a display power controller 6 through the part 8 and turns on the power supply of the device 2. In this case, the key input is invalidated since no signal is transmitted to a CPU 4a. Then, the key data are sent to a CPU 4 in the same way as the normal input.</p> |
