Abstract

PURPOSE: To avoid the hindrance to the interpretation of characters, by contituting the system so that the character display region is moved by the cursor for a given period and by effectively utilizing the space between lines in the cursor display of the CRT display unit.
CONSTITUTION: In the CRT display unit in which displayed screen is scanned with the raster scan and the location of the characters displayed is designated with the cursor, the vertical synchronizing signal 15 is fed to the count UP terminal 19 of the counter 101, and the output of the carry output pin 18 is fed to the count UP terminal of the counter 102. The output of the counters 101 and 102 is inputted to the comparator 11, and the output of the counter 102 is fed to the reset terminal of the counters 101 and 102 via the AND circuit 12. Further, the raster address signal 13 is fed to the comparator 11, it is compared with the given frequency of the counters 101 and 102 in bit unit, the output in agreement is fed to the AND circuit 12, and when the agreement with the cursor indicating signal 14 is taken, the cursor signal 17 is outputted.
