<p>An invention of the type that uses premarks (1) for marking in the letters themselves, which consists of placing a second premark (2) above each premark (1), the second premark (2) being made up of three small signs (3) arranged to form the imaginary vertexes of a triangle, in such a way that these signs (3) constitute the guideline for marking on that premark the supplementary tildes for the aforementioned letters, these tildes being the acute accents (7), grave accents (8) and circumflex (9), as well as the tilde (10) for the letter "ñ" and the dieresis (11). It is thus made much easier for the users of the form to mark in these symbols, because the marking in process only involves using straight lines that are clearly defined by the signs (3), and as the users mark in the correct strokes there is no risk of them being misinterpreted by the opto-electronic instruments that have to analyse the answers, because there are no marking errors.</p> |
