CONSTITUTION:When the depressing of a specific key of an input part 6 which requests the storage of an image displayed on a display part 5 is reported to a process executing means 8 and the image which is displayed needs to be stored because of the logic of a process as a result, the means 8 sends an image readout instruction to an image plane reading means 4. The means 4 reads the image out of the display part 5 according to the image readout instruction and sends the read image to a computer 7 by a transmitting means 3.
