Abstract

This is a visual alphanumerical display device in which the light from a lamp is sent through a transparent plastic block P and is reflected on a bevel B as in drawing 1. The device comprises a series of small superimposed plates so that light beams obtained at the bevelled extremities superpose themselves. Such is to provide all the sides, diagonals, medians of a rectangle as well as other dashes according to desired accuracy of character displaying. Drawing 2 shows all dashes obtained with small plates of drawing 1.

Visual Display

This is a visual alphanumerical display device in which the light from a lamp is sent through a transparent plastic block P and is reflected on a bevel B as in drawing 1. The device comprises a series of small superimposed plates so that light beams obtained at the bevelled extremities superpose themselves. Such is to provide all the sides, diagonals, medians of a rectangle as well as other dashes according to desired accuracy of character displaying. Drawing 2 shows all dashes obtained with small plates of drawing 1.

Numbers and characters are obtained by the selection of some light dashes. Thus each small plate communicates with one lamp which is lighted to obtain the corresponding dash as in drawing 3. Very thin plates are used and the width of light beams is defined according to the bevel slope.

Drawing 4 shows another visual numerical display device. It comprises ten thin translucent plates having a number engraved within. The desired number is displayed when the lamp corresponding to the plate is lighted. Such devices can be used side-by-side so as to display nonpermanent messages and can be controlled either by a keyboard or electrically with a position advancing device. No paper or tape is necessary.
