Abstract
PURPOSE: To secure an assured identification for the cursor in case the display positions overlap between the underline and the cursor, by giving blink control in preference to the cursor mark.
CONSTITUTION: When display timing signals S1 and S2 of the underline and the cursor are "1", gate A1 closes with gate A2 opening. And the output is inhibited for underline display timing signal S5, and cursor display timing signal S6 to which the blink control is given via blink timing signal S3 is delivered from gate A2. As a result, the underline at the position where the cursor mark overlaps is never displayed, and thus the cursor marks flashing in 2 Hz are displayed on slice lines #26W28 on the display screen synchronized with signal S6.
