Hierzu wird eine an der Aufzeichnungstrommel -»ο 7 befestigte, staubdichte Abdeckung 125, die die Ausnehmung 7| der Aufzeichnungstrommel 7 abdeckt, entferntRecording material sheet can be exchanged very easily. To do this, a - »ο 7 attached, dust-proof cover 125, which the recess 7 | the recording drum 7 covers, removed
An beiden Seiten der Aufzeichnungstrommel 7 befinden sich koaxial versetzte Scheiben 45 und 46, die auf der Trosnmelwelle 103 derart gelagert sind. daß sie. unabhängig voneinander drehbar sind. Ein Paar Führungsrollen 48, die an beiden Stirnseiten der Reinigungswalze 16 befestigt sind, berühren die Scheiben 45 und 46. In gleicher Weise rollen die stirnseitigen Ränder einer Bildübertragungswalze 47, die etwas langer als die axiale Abmessung der Trommel 7 ist, auf den Scheiben 45 und 46 ab, wie dies in den F i g. 4 und 5 gezeigt ist. Der Durchmesser der Scheiben 45 und 46 ist gleich dem der Aufzeichnungstrommel 7 einschließlich des über sie gespannten Aufzeichnungsmaterialblatts 8, so daß die Übertragungswalze 47 fest gegen das Aufzeichnungsmaterialblatt 8 gedruckt wird.On both sides of the recording drum 7 there are coaxially offset disks 45 and 46, which are mounted on the conveyor shaft 103 in this way. that they. can be rotated independently of each other. A pair of guide rollers 48 on both ends of the Cleaning roller 16 are attached, touch the disks 45 and 46. Roll in the same way end edges of an image transfer roller 47, which is slightly longer than the axial dimension of the drum 7, on disks 45 and 46, as shown in FIGS F i g. 4 and 5 is shown. The diameter of the disks 45 and 46 is the same as that of the recording drum 7 including the recording material sheet 8 stretched over them so that the transfer roller 47 is fixed is printed against the recording material sheet 8.
Ein das Kopierpapier vom Aufzeichnungsmaterialblatt 8 ablösendes Trennband 49 ist über 180° um die Übertragungswalze 47 herumgeschlungen und durch Rollen 50 bis 54 derart geführt, daß es zusammen mit der Übertragungswalze 47 bewegt wird. Es ist ersichtlich, daß das Trennband 49 von den Rollen 1SO bis 54 aus der Bewegungsbahn des Kopierpapiers au^elenkt wird.A separating tape 49 detaching the copy paper from the recording material sheet 8 is wound around the transfer roller 47 over 180 ° and is guided by rollers 50 to 54 in such a way that it is moved together with the transfer roller 47. It can be seen that the release tape is elenkt 49 of the rollers 1 SO to 54 from the path of movement of the copying paper au ^.
Wenn sich das Aufzeichnungsmaterialblatt 8 auf der Aufzeichnungstrommel 7 bei der Trommeldrehung von der Übertragungswalze 47 entfernt, wie es in Fig.5 angedeutet ist, so bildet sich ein Spalt zwischen der Übertragungswalze 47 und der Außenfläche der Abdeckung 125, da letztere gegenüber der Umfangsfläche der Scheiben 45 und 46 zurückgesetzt ist. Die Übertragungswalze wird dann also nur von den frei drehbar gelagerten Scheiben 45 und 46 abgestützt. Selbst wenn also die Aufzeichnungstrommel 7 stillgesetzt wird, wird die Übertragungswalze 47 mit dem Trennband 49 weitergedreht, so daß das Kopierpapier P sicher in die Fixiereinrichtung 55 weitergefördert werden kann. Diese Möglichkeit einer Weiterdrehung von Übertragungswalze 47 und Trennband 49 bei stillstehender Aufzeichnungstrommel 7 verhindert zugleich eine önliche Erhitzung der Walze und des Trennbands durch die Fixiereinrichtung 55. Schließlich kann neben der Übertragungswalze auch die Zuführeinrichtung für das Kopierpapier bei stillgesetzter Aufzeichnungstrommel 7 weiterlaufen.If the recording material sheet 8 on the recording drum 7 moves away from the transfer roller 47 as the drum rotates, as indicated in FIG 45 and 46 is reset. The transfer roller is then only supported by the freely rotatably mounted disks 45 and 46. Even if the recording drum 7 is stopped, the transfer roller 47 with the separating tape 49 continues to rotate, so that the copy paper P can be safely conveyed further into the fixing device 55. This possibility of further rotation of the transfer roller 47 and separating tape 49 when the recording drum 7 is at a standstill also prevents the roller and the separating tape from being heated up by the fixing device 55. Finally, in addition to the transfer roller, the feed device for the copy paper can continue to run when the recording drum 7 is stopped.
