<p>PURPOSE:To save power without impairing operability by solving a problem that the usable duration of a battery is short at the time of drive by the battery in a portable information processor provided with an input part like a keyboard, etc. CONSTITUTION:A first processing block 1 connected to an information input block 97 including the keyboard 201 is provided, and it is connected to a second processing block 98 to which a display part 2 provided with a memory effect is connected. In response to the input of the keyboard, etc., the first processing block 1 starts the second processing block 98 being in a standstill state, and after changing the display of the display part 2, it stops the power supply or the operation of the both. At that time, the display of the display part 2 is held by the memory effect. Thus, the information processor whose power consumption is drastically reduced without impairing the display characteristic of the display part 2 can be obtained.</p> |
