Abstract

A typewriter display includes an annunciator to indicate the line on the sheet of paper on which typing is occurring. The annunciator is displayed in reverse video (colors of background and characters reversed) when the text line is within the bottom inch of the paper. The location of a text line on a sheet of paper is digitally indicated in an annunciator of a typewriter display. When typing in ten pitch or twelve pitch, there are six lines of text per vertical inch while fifteen pitch has eight lines of text per vertical inch; the line counter automatically adjusts its count for this. Thus, for an eleven-inch sheet of paper, the line counter has a maximum count of sixty-six in ten or twelve pitch and eighty-eight in fifteen pitch.

Typewriter Line Counter Having a Digital Display

A typewriter display includes an annunciator to indicate the line on the sheet of paper on which typing is occurring. The annunciator is displayed in reverse video (colors of background and characters reversed) when the text line is within the bottom inch of the paper. The location of a text line on a sheet of paper is digitally indicated in an annunciator of a typewriter display. When typing in ten pitch or twelve pitch, there are six lines of text per vertical inch while fifteen pitch has eight lines of text per vertical inch; the line counter automatically adjusts its count for this. Thus, for an eleven-inch sheet of paper, the line counter has a maximum count of sixty-six in ten or twelve pitch and eighty-eight in fifteen pitch. The entire line counter annunciator is displayed in reverse video when the text line is within one inch of the bottom of the page. This immediately attracts the typist's attention since the line counter annunciator stands out on the display. The typical bottom margin used by a typist is one inch from the bottom of the sheet of paper. The display annunciator indicates when the sheet of paper is not exactly on a line. For example, if the text line is slightly below line 10 so as to be between lines 10 and 11, "10 +" is shown on the display annunciator.
