Description

Vorrichtung zur Herstellung photoelektrisch auswertbarer Zeichen Die Erfindung behandelt eine Vorrichtung zur Herstellung photoelektrisch auswertbarer Zeichen mittels einer Schreibmaschine.Device for the production of photoelectrically evaluable characters Invention deals with a device for producing photoelectrically evaluable Character using a typewriter.

Es ist bereits vorgeschlagen worden, Striche, die mittels einer Schreibmaschine hergestellt werden könnten, als Marken zum Steuern von Anzeigegeräten zu verwenden, indem vorn einer geeigneten Beleuchtungsvorrichtung ein der Strichbreite angepaßter schmäler Lichtfleck auf das die Marken tragende Papier projiziert und von dort in eine benachbarte Photozelle reflektiert wird, der zum Verlöschen kommt, wenn @er auf eine Strichmarke gerät, wodurch die zum Steuern angestrebte Stromschwankung hervorgerufen wird.It has already been suggested that strokes made by means of a typewriter could be made to use as brands for controlling display devices, by fitting a suitable lighting device to the line width at the front A narrow light spot is projected onto the paper bearing the marks and from there into an adjacent photocell is reflected, which is extinguished when @er on a line mark, whereby the current fluctuation sought for control is caused.

Die Wertgebung geschieht durch verschiede;ne Stellung der Marken und durch Kombination dieser Markenstellungen, so daß beispielsweise mit vier Marken die Ziffern ,eins bis neun auswertungsfähig dargestellt werden können.The valuation occurs through different positions of the brands and by combining these brand positions, so that for example with four brands the digits, one to nine, can be displayed for evaluation.

Die Aufgabe der vorliegenden Erfindung ist, den Mangel, für jeden Begriff die diesem zugeordneten Marken in ihren verschieden,en Stellungen mit der Schreibmaschine einzeln herstellen zu müssen, durch Sondertypen für jede Markenkombination zu beseitigen.The object of the present invention is to find the defect for everyone Term the brands assigned to this in their various positions with the Having to manufacture typewriters individually, due to special types for each brand combination to eliminate.

Umeine Strichkombination. möglichst in der Größe eines gewöhnlichen Schreibmaschinenschriftzeichens halten zu können, müssen die Einzelstriche möglichst eng beieinanderstehen. Es genügt, den Zwischenraum nur so breit zu halten, daß der Lichtfleck des Abfühlstrahles dessen weißen Papieruntergrund voll bedecken kann.Um a combination of lines. if possible the size of an ordinary one In order to be able to hold typewriter characters, the single lines must be used if possible stand close together. It is enough to keep the space so wide that the The light spot of the sensing beam can completely cover the white paper background.

Weil die durch die Strichkombination gebildeten Zeichen nicht für jedermann lesbar sind, so wird @es zuweilen zweckmäßig sein, dem Sonderzeichen das übliche gleichwertige Schriftzeichen beizufügen. Besteht dabei die Gefahr, daß diese Zusatzzeichen in die Abfühlbahn des Taststrahles geraten könnten, dann empfiehlt ges sich, die Zusatzzeichen in einer für die Photozelle unwirksamen Farbe zu schreiben.Because the characters formed by the stroke combination are not for are readable by everyone, @es will sometimes be useful, the special character das Usual equivalent characters to be attached. There is a risk that this Additional characters could get into the sensing path of the probe beam, then recommends be sure to write the additional characters in a color that is ineffective for the photocell.
