イ装置におけるカーソル幅制御回路。[Claims for Utility Model Registration] (1) In a character display device that displays a cursor at a predetermined position on a CRT display screen based on a cursor signal from a CRT controller, the characters displayed on the CRT display screen loading the cursor width data from a memory storing corresponding cursor width data based on an AND output of a character clock signal and a cursor signal from the CRT controller;
A cursor width control circuit for a character display device, comprising: a cursor video signal creation circuit that creates a cursor video signal corresponding to the cursor width data. (2) The cursor video signal creation circuit includes a decoder that decodes a cursor width code stored in memory, and output data of the decoder using a character clock signal as a clock signal and a cursor signal from a CRT controller as a shift/load signal. A cursor width control circuit in a character display device according to claim 1, comprising a shift register for loading a cursor video signal and outputting a corresponding cursor video signal.
