Liquid droplets recording device
EP 0092229 A2
Resumen
In the recording device there is at least one nozzle for writing which is arranged in a holder. If required, writing liquid from the nozzle can be applied to a recording medium arranged in front of the outlet opening of said nozzle. In order to avoid undesired leakage of writing liquid from the nozzle and to prevent the outlet opening of the nozzles becoming blocked by a layer of liquid and paper dust, provision is made for the side (6) of the nozzle holder (10), facing the recording medium (3), to be provided with a coating (15), the surface tension of which is lower than the surface tension of the writing liquid. <IMAGE>

    Die Erfindung betrifft ein mit Flüssigkeitströpfchen arbeitendes Schreibgerät, wobei zum Schreiben mindestens eine in einem Träger angeordnete Düse vorhanden ist, aus der bei Bedarf Schreibflüssigkeit herausgestossen und auf einen vor der Austrittsöffnung der Düse angeordneten Aufzeichnungsträger aufgebracht wird. The invention relates to an operating with liquid droplets writing instrument, wherein for writing at least one arranged in a carrier nozzle is present, is pushed out when required writing fluid and applied to a arranged in front of the outlet opening of the nozzle recording medium.

    Ein solches Schreibgerät ist durch die DE-OS 25 27 647 bekannt. Such a writing instrument is known from DE-OS 25 27 647th Bei Schreibgeräten dieser Art passiert es häufig, dass die dem Aufzeichnungsträger zugewandte Seite des Düsenträgers, insbesondere um die Düsen herum, durch Schreibflüssigkeit, die aus den Düsen heraussikkert, benetzt wird. In writing instruments of this type it often happens that the surface facing the recording medium side of the nozzle carrier, in particular around the nozzle, by writing fluid, the heraussikkert from the nozzles is wetted. Dies hat den Nachteil, dass Papierstaub vom Aufzeichnungspapier auf der Oberfläche des Düsenträgers haftet und zusammen mit der SchreibElüssigkeit einen Belag bildet, der die Schreibfunktion verschlechtert. This has the disadvantage that paper dust from the recording paper adheres on the surface of the nozzle support and forming a coating together with the SchreibElüssigkeit which deteriorates the write function. So kann z. B. der Belag einen Teil der Düsenmündung verstopfen, so dass die Richtung der herausgestossenen Tropfen beeinflusst wird. Thus, for. Example, the covering can clog a part of the nozzle orifice, so that the direction of the pushed-out drops is influenced.

    Um zu vermeiden, dass Schreibflüssigkeit aus den Düsen heraussickert, kann z. B. durch eine Saugvorrichtung in dem Schreibflüssigkeitssystem ein bestimmter Unterdruck erzeugt werden. In order to avoid that the writing fluid oozing from the nozzles, for. Example, a certain underpressure can be generated by a suction device in the writing fluid system. Beim Ausschalten des Schreibgerätes lässt der UnterdrucK jedoch nach, so dass wieder Schreibflüssigkeit heraussickern kann. However, when you turn off the writing instrument of the negative pressure decreases, so that can ooze writing fluid again.
  • [0004] [0004]
    Eine weitere Möglichkeit, das Heraustropfen der Schreib-Lst 1 TT flüssigkeit aus den Düsen zu verhindern,ist, den Flüssigkeitsbehälter im Verhältnis zum D üsenträger niedriger anzubringen, so dass ein Unterdruck im Flüssigkeitssystem erhalten wird. A further possibility, the dripping of the write Lst to prevent 1 TT liquid from the nozzles is to mount the liquid container relative to D üsenträger lower, so that a negative pressure is obtained in the fluid system. Beim Ausschalten des Gerätes wird die im System vorhandene Schreibflüssigkeit in den Behälter zurückgesaugt. When you turn off the device, the existing system in writing fluid is sucked back into the container. Beim Einschalten des Gerätes ist eine gewisse Zeitverzögerung nicht zu vermeiden, da die Schreibflüssigkeit vom Behälter zu den Düsen transportiert werden muss, bevor geschrieben werden kann. When the device a certain time delay can not be avoided because the writing fluid from the container to be transported to the nozzles before it can be written.

    Der Erfindung liegt die Aufgabe zugrunde, ein Schreibgerät der eingangs genannten Art zu schaffen, bei dem ein Heraussickern von Schreibflüssigkeit aus der Düse nicht erfolgt, so dass die dem Aufzeichnungsträger zugewandte Seite des. Düsenträgers trocken bleibt. The invention has for its object to provide a writing instrument of the aforementioned type, in which a seepage of writing fluid from the nozzle does not take place, so that the surface facing the recording medium side of the. Nozzle carrier remains dry.
  • [0006] [0006]
    Diese Aufgabe ist erfindungsgemäss dadurch gelöst, dass die dem Aufzeichnungsträger zugewandte Seite des Düsenträgers mit einer Schicht versehen ist, deren Oberflächenspannung niedriger als die Oberflächenspannung der Schreibflüssigkeit ist. This object is inventively achieved in that the surface facing the recording medium side of the nozzle support is provided with a layer whose surface tension is lower than the surface tension of the recording liquid. Die flüssigkeitsabstossende Schicht hält die Schreibflüssigkeit zurück, so dass sie nicht aus der Düse heraussickert. The flüssigkeitsabstossende layer restrains the recording liquid, so that they do not ooze out from the nozzle. Ferner bleibt kein Papierstaub am Träger haften, so dass nunmehr eine gut definierte Richtung der Tropfen und damit eine hohe Schreibqualität erreicht ist. Further, no paper dust on the support sticks, so that now a well-defined direction of the drops and thus a high writing quality is reached. Durch die erfindungsgemässe Schicht braucht auch kein Unterdruck im Flüssigkeitssystem erzeugt zu werden. The inventive layer also no negative pressure in the fluid system needs to be created.
  • [0007] [0007]
    In einer Weiterbildung der Erfindung wird vorgeschlagen, dass die Schicht im Bereich der Austrittsöffnung der Düsen abgeschrägt ist. In a development of the invention it is proposed that the layer is bevelled in the region of the outlet opening of the nozzle. Dadurch ist erreicht, dass die Düsen mit Schraibflüssigkeit gefüllt sind, was nicht der Fall ist, wenn die Schicht bis in die Düse gelegt wird. Thereby is achieved that the nozzles are filled with Schraibflüssigkeit, which is not the case when the layer is applied to the nozzle. Wenn die Düse nicht ganz mit Schreibflüssigkeit gefüllt ist, sinkt die Schreibqualität bzw. die Schrift kann ganz ausbleiben. When the nozzle is not completely filled with writing fluid, the writing quality and the font drops can completely fail.
