Abstract
PURPOSE: To facilitate erasion of the characters and the re-display after erasion for the display unit displaying the characters, the symbols and others by providing the memory to memorize the control information indicating whether or not the display information is displayed on the screen in addition to the memory to memorize the display information.
CONSTITUTION: One character or one symbol comprising n-bit and l-word is memorized in memory 1, and the information which is added to the same address as the word address of memory 1 selected first and indicates whether the character or the symbol of the l-word on the screen is memorized in memory 7. Thus memory device 2 is constituted. The character or symbol on the screen can be erased just by writing "1" into memory 7 via input information controller 3. Memory 1 is read out by sequential counter 5, and at the same time memory 7 is read out. And in the case of "1", display information controller 8 generates the information displaying nothing from output information controller 9 and then receives the display control by control information 7 for next memory 1 after readout of l-word.
