Abstract: A positioning unit for use in completing forms at a word processing station having a display unit, a computer, a text input device and a printer. The positioning unit has a transparent contact plate into which a copy of the form is placed and underneath which a movable position marker directs onto the copy a light dot which is moved in synchronism with a cursor on a screen of a display unit. The position marker is mounted on a frame below the contact plate and is movable in line and column directions parallel to the contact plate so as to follow the movement of the cursor, so that an operator can observe where on a corresponding form in the printer text entered into a computer via the input device and viewable on the screen, will be typed on the printer.
