Claims

[Claim for Utility Model Registration] A display device equipped with a memory method character generator for storing data to be displayed, a holding means for holding cursor display position information, and a display section for displaying character patterns, ruled lines, and a cursor. In the above, the display unit has a character display line that sequentially displays characters configured in a matrix of an appropriate size in the row direction, and a ruled line and a cursor that are displayed on the same line along the character display line and separately from the character display line. The display device has a ruled line/cursor display line for displaying the display, and also includes the above-mentioned holding means for specifying a position corresponding to which one-character display zone on the display section the cursor is to be displayed in synchronization with the display scanning of the display section. However, circuit means for synchronizing the scanning of ruled lines and cursor display lines in the display scanning so as to display the cursor with preset ruled lines and cursor display lines, and circuit means for determining the presence or absence of signal information for displaying ruled lines. A display device for displaying ruled lines, comprising a detection means for detecting, and a selection circuit means for controlling a portion of the ruled line to be displayed as a cursor in a blinking manner or to display the cursor in a constant light state in response to the output of the detection means. A cursor is displayed at the position, and if a ruled line is previously displayed at the cursor display position, the part of the ruled line that will be displayed as the cursor is displayed blinking, and if no ruled line is displayed, the cursor is displayed as a constant light. A display device characterized by:
