Description

Diktiermaschinen mit blattförmigen Magnetogrammträgern sind bekannt. Die Blätter werden ähnlich wie bei der üblichen Schreibschrift zeilenweise quer zu ihrer Laufrichtung beschriftet. Werden diese Blätter in das D'iktierge'rät eingeführt, sei es blattweise, sei es von einer Vorratsspule aus, so passieren sie zweckmäßig eine Umlenkrolle oder -schiene, die vor der Schreibzeile angeordnet ist und sich über die gesamte Breite des Aufzeichnungsträgers erstreckt. Erfindungsgemäß wird dies Umlenkorgan gebildet durch den Löschkopf, der sich gemäß der Erfindung quer über die gesamte Breite des Aufzeichnungsträgers erstreckt. Zweckmäßig wird er durch ein Rohr runden, oblongen oder ähnlichen Querschnitts mit Schlitz längs einer Mantellinie ausgebildet, in dem das Löschfeld erzeugt wird. Hierzu kann eine Wicklung durch den Schlitz aufgebracht werden. Es kann natürlich auch ein Dauermagnet geeigneter Form Verwendung finden.Dictation machines with sheet-shaped magnetogram carriers are known. The sheets of paper are transverse line by line, similar to conventional cursive writing labeled for their direction of travel. If these leaves are inserted into the dictator, be it sheet by sheet, be it from a supply reel, they pass appropriately a deflection roller or rail, which is arranged in front of the writing line and is Extends over the entire width of the recording medium. According to the invention this deflection element formed by the erase head, which according to the invention is transverse Extends over the entire width of the recording medium. It becomes expedient by a tube of round, oblong or similar cross-section with a slot along a surface line formed in which the erase field is generated. A winding can be used for this purpose the slot can be applied. Of course, a permanent magnet can also be more suitable Find form use.

Der Löschkopf kann für Gleich- oder Wcchselstronilöschung vorgesehen sein. Im letzteren Fall ist eine hohe Frequenz nicht erforderlich, weil die Geschwindigkeit des Bandes beim Lauf durch das Löschfeld sehr klein ist, so daß die Wellenlänge des zurückbleibenden Löschfeldes urbeachtlich ist: zudem liegt sie quer zur Schreibrichtung, so daß sie schon aus diesem Grunde nicht störend wirkt.The erase head can be designed for identical or alternating drone erasure be. In the latter case, a high frequency is not required because of the speed of the tape is very small when running through the erasing field, so that the wavelength of the remaining erase field is very important: it is also at right angles to the direction of writing, so that for this reason alone it does not have a disruptive effect.

Man kann dem erfindungsgemäßen Löschkopf alle Formen geben, die für Löschköpfe als förderlich erkannt sind.You can give the erase head according to the invention all shapes that are for Erase heads are recognized as beneficial.

In der Figur ist, zum Teil schematisch, der Gegenstand der Erfindung beispielsweise dargestellt. Das Magnettongerät befindet sich in dem Gehäuse i. Der Aufzeichnungsträger 2 läuft über die Kante 3 zur Schreibzeile 4 und wird dabei durch den Löschkopf 5 geführt. Der Löschkopf 5 ist als Rohr oblongen Querschnitts dargestellt, welches bei 6 geschlitzt ist, so daß hier längs einer Mantellinie das Löschfeld entsteht, das durch die Wicklung 7 erzeugt ist. Die Erregung wird zweckmäßig aus dem Wechselstromnetz entnommen, das im allgemeinen verfügbar ist. Die Wechselstromlöschung mit technischem Wechselstrom ist zwar an sich bekannt, eignet sich aber besonders für den der Erfindung zugrundeliegenden Fall der Beschriftung quer zur Laufrichtung.In the figure is, partly schematically, the subject of the invention for example shown. The magnetic device is located in the housing i. Of the Recording medium 2 runs over edge 3 to write line 4 and is thereby through the erase head 5 performed. The extinguishing head 5 is shown as a tube with an oblong cross-section, which is slotted at 6, so that here the erase field along a surface line arises, which is generated by the winding 7. The excitement is expediently off taken from the AC network that is generally available. The AC extinction with technical alternating current is known per se, but is particularly suitable for the case on which the invention is based, the lettering transversely to the direction of travel.
