Abstract

PURPOSE:To eliminate need to move a pointing device at the time of return to a required position by providing a means where the extent of movement of the pointing device is stored and storing the extent of movement of the pointing device with respect to movement to a certain determined position. CONSTITUTION:Data inputted from the pointing device is divided to X and Y coordinates by the movement direction to always increase or decrease an X coordinate counter 100 and a Y coordinate counter 200. When the extent of movement of the pointing device should be stored, a control circuit 700 outputs X and Y coordinate counter values to storage devices 300 to 320 and storage devices 400 to 420 respectively to store them. Stored data is outputted to X and Y coordinate counters 100 and 200 by a control signal 702 of the control circuit 700. Thus, a cursor is returned to the required position without moving the pointing device.
