Abstract

Disclosed is a control circuit which controls the speed of cursor movement. A display screen of a display terminal has a fixed display area. Characters are displayed in the display area in various display mode, e.g. 24x80, 32x80, 43x80 and 27x132 characters. The cursor is continuously moved on the display area in response to a depression and holding of the cursor move key. When an operator switches the display mode from 24x80 to 43x80, he can see large numbers of characters in the display area. But, the speed of cursor movement to a specific character position becomes slow. It is required, therefore, to adjust or control the speed of the cursor movement at appropriate speed to the selected mode. Referring to the figure, a table is provided which stores count values for the display modes.
