ABSTRACT:
The invention is applicable to an apparatus which receives a sequence of character-representative signals and which generates stroke signals that are suitable for controlling a scanned display to present the sequence of characters on the display. This type of system typically includes timing generator means for generating timing signals which are synchronized with the display scan and character storage means for storing the character-representative signals and periodically reading out character-representative signals which correspond to a character in the sequence. This type of apparatus also typically includes stroke generating means responsive to the timing signals and the character-representative signals for producing a stroke of a character to be displayed. In accordance with the invention there is provided a system for presenting predetermined adjacent characters in overlapping positions on the display. Means are provided for sensing the successive occurrence of at least one preselected pair of character-representative signals and for thereupon generating an occurrence indication. Further provided are means responsive to the occurrence indication for accelerating the readout of the stroke of the second-occurring of the preselected pair of characters. In the preferred embodiment of the invention, means are provided for storing the last-occurring portion of the stroke of the first-occurring of the preselected pair of characters. The stored stroke portion is read out in conjunction with the stroke of the second-occurring of the preselected pair of characters.
