Abstract
Description
Kassette für Farbband für schreibende Maschinen Farbbänder werden bekanntlich nicht schon bei einem Durchlauf durch die Maschine, in der sie gebraucht werden, verbraucht. In allen schreibenden Maschinen, und das sind neben Schreibmaschinen üblicher Art beispielsweise auch mit einem Schreibsystem ausgerüstete Rechenmaschinen, ist deshalb der Einbau eines relativ komplizierten und aufwendigen Umschaltmechanismus für den Banddurchlauf erforderlich.Cassette for ink ribbon for writing machines to be ink ribbons as is well known, not already in one pass through the machine in which it is needed are consumed. In all typing machines, and these are next to typewriters of the usual type, for example, calculating machines equipped with a writing system, is therefore the installation of a relatively complicated and expensive switchover mechanism required for the belt to pass through.
Die Erfindung hat es sich zur Aufgabe gestellt, eine Möglichkeit zu schaffen, ohne solch einen Umschaltmechanismus auszukommen. Sie verwendet dazu den bereits bekannten Gedanken, ein Schreibband nicht von einer frei angeordneten Spule zur anderen laufen zu lassen, sondern den Banddurchlauf innerhalb einer kassettenartigen Einheit abzuwickeln.The invention has set itself the task of providing a possibility manage without such a switching mechanism. She uses the already known ideas, a writing tape not from a freely arranged reel to let the other run, but the tape run inside a cassette-like To handle the unit.
Solche Kassetten haben den Vorteil, daß der Bandwechsel einfach, rasch und praktisch verschmutzungsfrei vorgenommen werden kann. Aber auch bei Verwendung solcher Kassetten war bisher stets der eingangs schon werwähnte Umschaltmechanismus in der Maschine zum Umschalten des Bandablaufs erforderlich.Such cassettes have the advantage that the tape change is easy and quick and can be carried out practically free of contamination. But also when using Such cassettes have always been the switching mechanism mentioned at the beginning Required in the machine to switch over the conveyor belt.
Die Erfindung löst Oese Aufgabe dadurch, daß in einem symmetrischen Gehäuse zwei Farbbandspulen zum Ab- bzw.The invention solves the problem in that in a symmetrical Housing two ribbon reels for unwinding and unwinding
Aufwickeln des Farbbandes untergebracht sind und jeweils die zum Aufwickeln des durchgelaufenen Bandes bestimmte Farbbandspule eine Anzeige für den Stand des Banddurchlaufes besitzt.Winding the ribbon are housed and each one for winding The ribbon reel determined by the run-through tape displays the status of the Belt run-through.
Die Kassette kann zusätzlich Umlenkrollen oder grad freie Umlenkradien für den Bandtransport besitzen. Vorzugsweise werden sich im Kassettenkörper Sichtfenster wechselseitig auf der Oberseite der Kassette jeweils auf der Seite der Aufwickelspule befinden.The cassette can also have deflection rollers or degree-free deflection radii for the tape transport. Viewing windows are preferably located in the cassette body alternately on the top of the cassette on the side of the take-up spool are located.
Die beigefUgte Skizze zeigt den Gegenstand der Erfindung in beispielshafter Aus führungs form.The attached sketch shows the subject matter of the invention by way of example Execution.
Figur 1 zeigt eine erfindungsgemaße Kassette 1 im Zeitpunkt des Startes eines neuen Farbbandes 2 auf der vollen Farbbandspule 3. Der Spulenkern .ist hier für die Sicherstellung des Farbbandtransports verzahnt 5. Das Farbband 2 läuft über Umlenkvorrichtungen 6 und 7, die hier als Umlenkrollen dargestellt sind, zur leeren Farbbandspule 8 und wird dort aufgewickelt. Das Fenster lo auf der Oberseite der Kassette läßt den Farbbandablauf Farbbandverbrauch erkennen.FIG. 1 shows a cassette 1 according to the invention at the time of start a new ribbon 2 on the full ribbon spool 3. The spool core .is here To ensure the ribbon transport, toothed 5. The ribbon 2 overflows Deflection devices 6 and 7, which are shown here as deflection rollers, to empty Ribbon spool 8 and is wound up there. The window lo on top of the The cassette shows the ribbon run out. Ribbon consumption.
In Figur 2 hat das Farbband 2 seinen Durchlauf beendet.In Figure 2, the ribbon 2 has ended its passage.
Das Fenster lo ist leetund die Spule 8 hat das gesamte Band aufgenommen. Das bei dieser Spule angedeutete Fenster 11 ist zunächst nicht sichtbar. Dazu muß die Kassette erst um 1800 gedreht werden.The window lo is empty and the reel 8 has taken up the entire tape. The window 11 indicated in this coil is initially not visible. To do this must the cassette cannot be rotated until 1800.
Das zeigt Figur 5. Die Drehung Ist entsprechend Pfeil 12 erfolgt, und nunmehr befindet sich die Spule 8 mit dem Fenster 11 auf der Seite, von der aus das Band abläuft, und der ganze Vorgang wiederholt sich wie bereits beschfieben.This is shown in Figure 5. The rotation has taken place according to arrow 12, and now the coil 8 with the window 11 is on the side from which the tape runs out, and the whole process is repeated as already described.
Der Querschnitt zu Figur 5 läßt die Verzahnungen 5 am Spulenkern und die Umlenkvorrichtung 6 noch einmal erkennen.The cross-section to Figure 5 leaves the teeth 5 on the coil core and recognize the deflection device 6 again.
