Description
Weehselzeichenanor dnung. Es sind Wechselzeichensysteme bekannt, bei denen durch abwechselndes Ausleuchten in bestimmter Weise angeordneter Blendkam- mern verschiedene Zeichen, z. B. Buchstaben oder Zahlen, in Leuchtschrift wiedergegeben werden.
Ferner sind Wechselzeichensysteme be kannt, bei denen die gewünschten Zeichen als Blenden ausgebildet sind, wobei jeweils die Blende des abzubildenden Zeichens mittels eines elektromechanischen Schaltapparates vor eine Lichtquelle mit Linsensystem ge schoben und das Zeichen auf einem Schirm, z. B. einer Milchglassoheibe, abgebildet wird.
Erstere Apparate haben den Nachteil, dass man an bestimmte Zeichenformen gebun den ist, da eine bestimmte Anzahl Blend- kammern in fester Anordnung für die Wieder gabe aller Zeichen verwendet wird.
Die zweite Ausführung benötigt zur Ver schiebung der Blenden komplizierte und teure Schaltapparate, die leicht zu Störungen Anlass geben und geräuschvoll arbeiten. Vorliegende Erfindung vermeidet beide Mängel. Die erfindungsgemässe Wechselzei- chenanordnung zeichnet sich dadurch aus, dass jedem darzustellenden Zeichen eine Blende und eine Lichtquelle zugeordnet sind und dass die Blenden und Lichtquellen fest und derart angeordnet sind, dass das Bild jedes Zeichens an der gleichen Stelle eines Auf fangschirmes erscheint.
In beiliegender Zeichnung, welche ein Ausführungsbeispiel des Erfindungsgegenstan des darstellt, bedeuten 1, 1 a und 1 b die Blenden der gewünschten Zeichen, z. B. die Zahlen und Buchstaben. Hinter jeder Blende befindet sich eine annähernd punktförmige Lichtquelle 2, 2ca und 2b, z. B. eine Fokus lampe. Die Lichtquellen sind in der Weise hinter den Blenden angeordnet, dass das auf dem Schirm 3 entstehende Abbild jedes Zeichens jeweils an der gleichen Stelle auf dem Schirm sichtbar wird, wobei jeweils nur die dem gewünschten Zeichen zugeordnete Lichtquelle leuchtet. Hierbei kann das Licht vor Auftreffen auf den Schirm durch eine oder mehrere Lin sen gesammelt werden.
Phrase arrangement. Variable sign systems are known in which, by alternately illuminating glare chambers arranged in a certain way, different signs, e.g. B. letters or numbers are displayed in neon letters.
Furthermore, alternating character systems are known in which the desired characters are designed as apertures, with the aperture of the character to be mapped by means of an electromechanical switching device in front of a light source with a lens system and pushed the characters on a screen, for. B. a frosted glass window is shown.
The former devices have the disadvantage that one is bound to certain character shapes, since a certain number of blind chambers are used in a fixed arrangement for the reproduction of all characters.
The second version requires complicated and expensive switching devices to move the diaphragms, which easily give rise to malfunctions and work noisily. The present invention avoids both of these shortcomings. The alternating character arrangement according to the invention is characterized in that each character to be displayed is assigned a screen and a light source and that the screens and light sources are fixed and arranged in such a way that the image of each character appears at the same point on a collecting screen.
In the accompanying drawing, which represents an embodiment of the subject matter of the invention, 1, 1 a and 1 b mean the aperture of the desired characters, for. B. the numbers and letters. Behind each diaphragm there is an approximately point-shaped light source 2, 2ca and 2b, e.g. B. a focus lamp. The light sources are arranged behind the screens in such a way that the image of each character created on the screen 3 is visible at the same point on the screen, with only the light source assigned to the desired character shining. Here, the light can be collected by one or more lenses before it hits the screen.
