Description

Die Erfindung betrifft eine Gehäuseabdeckung gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a housing cover according to the preamble of patent claim 1.

Bei Textendgeräten, wie Hardcopy-Drucker, Datendrucker oder dergleichen ist es allgemein bekannt, diese so auszugestalten, dass damit wahlweise Einzel- bzw. Endlospapier beschrieben werden kann. Bei der Verwendung als Datendrukker wird überwiegend mit Endlospapier geschrieben, weswegen der Drucker zur Minderung der Geräuschentwicklung bis auf einen entsprechenden Austrittsschlitz für das Endlospapier über den Papierschacht vollständig abgedeckt ist.In the case of text end devices, such as hardcopy printers, data printers or the like, it is generally known to design them in such a way that single or continuous paper can be written with them. When used as a data printer, writing is predominantly made with continuous paper, which is why the printer is completely covered over the paper chute to reduce noise, except for a corresponding exit slot for the continuous paper.

Zum Zuführen von Einzelblättern wird dabei entweder der Deckel geöffnet, um den Papierschacht freizulegen, oder im Deckel befindet sich ein zusätzlicher Zuführungsschlitz.To feed single sheets, either the lid is opened to expose the paper chute, or there is an additional feed slot in the lid.

Dieser zusätzliche Zuführungsschlitz vermindert die Geräuschdämmung, was insbesondere beim Dauerbetrieb mit Verwendung von Endlospapier störend ist.This additional feed slot reduces the noise insulation, which is particularly troublesome in continuous operation with the use of continuous paper.

Zur Zufuhr von Einzelblättern ist es ausserdem notwendig, im Drucker entsprechende Führungen anzuordnen, um ein richtiges Einlegen des Papierblattes zu erleichtern und um einen ungestörten Papiertransport zu garantieren.To feed single sheets, it is also necessary to arrange appropriate guides in the printer to facilitate correct loading of the paper sheet and to guarantee undisturbed paper transport.

Aus der Literaturstelle IBM Technical Discloeure Bulletin Vol. 24, No. 8 page 4348, «Cover Section for paper opening of a printer», Mott und Shakib, ist eine Gehäuseabdeckung der eingangs genannten Art bekannt. Die Abdeckung enthält einen Klappdeckel der im hochgeklappten Zustand als Anlagefläche für das Papier dient. Im geschlossenen Zustand deckt der Klappdeckel die Papierzuführung ab.From the IBM Technical Disclosure Bulletin Vol. 24, No. 8 page 4348, "Cover Section for paper opening of a printer", Mott and Shakib, a housing cover of the type mentioned is known. The cover contains a hinged lid which, when folded up, serves as a contact surface for the paper. When closed, the hinged lid covers the paper feed.

Aufgabe der Erfindung ist es, eine Gehäuseabdeckung für wahlweise mit Endlos- und Einzelpapier betriebene Druckeinrichtungen bereitzustellen, die so ausgestaltet ist, dass sie bei optimaler Geräuschdämmung neben dem Betrieb mit Endlospapier ein einfaches Einlegen von Einzelblättern ermöglicht.The object of the invention is to provide a housing cover for printing devices operated optionally with continuous and single paper, which is designed in such a way that, with optimum noise insulation, it enables simple insertion of single sheets in addition to operation with continuous paper.

Diese Aufgabe wird bei einer Gehäuseabdekkung der eingangs genannten Art gemäss dem kennzeichnenden Teil des Patentanspruchs 1 gelöst. Weitere vorteilhafte Ausführungsformen sind in den Unteransprüchen gekennzeichnet.This object is achieved with a housing cover of the type mentioned at the outset in accordance with the characterizing part of patent claim 1. Further advantageous embodiments are characterized in the subclaims.

Dadurch, dass der Klappdeckel im eingeklappten Zustand mit seiner Vorderkante und der Gehäuseabdeckung einen Austrittsschlitz für das Endlospapier und im hochgestellten Zustand eine Papieranlagefläche für das einzulegende Endlospapier bildet, lässt sich die Abdeckung in Drukkern sowohl für Endlospapier als auch für Einzelpapier verwenden.The fact that the hinged lid with its front edge and the housing cover forms an exit slot for the continuous paper in the folded state and a paper contact surface for the continuous paper to be inserted in the raised state, the cover in printers can be used both for continuous paper and for single paper.

Durch den Klappdeckel wird im hochgeklappten Zustand das Einlegen von Einzelblättern wesentlich erleichtert. Trotzdem ist durch den Klappdekkel beim Betrieb mit Endlospapier eine optimale Geräuschdämmung garantiert.The hinged lid makes it much easier to insert single sheets when folded up. Nevertheless, the hinged lid guarantees optimal noise insulation when operating with continuous paper.

Auf dem Klappdeckel angeordnete verstellbare Papieranschläge mit zugehöriger Papierausrichtsskala erleichtern die Justierung des Einzelblattes beim Einlegen.The adjustable paper stops on the hinged lid with the associated paper alignment scale make it easier to adjust the single sheet when inserting it.

Die gesamte Vorrichtung kann kostengünstig im Kunststoffspritzverfahren hergestellt werden.The entire device can be manufactured inexpensively in the plastic injection molding process.

Ausführungsformen der Erfindung sind in den Zeichnungen dargestellt und werden im folgenden beispielsweise näher beschrieben. Es zeigenEmbodiments of the invention are shown in the drawings and are described in more detail below, for example. Show it

Fig. 1 eine schematische Darstellung der erfindungsgemässen Gehäuseabdeckung mit einem einteiligen Klappdeckel undFig. 1 is a schematic representation of the housing cover according to the invention with a one-piece hinged cover and

Fig. 2 eine schematische Darstellung der Gehäuseabdeckung mit einem zweiteiligen Klappdeckel. Die Figuren zeigen jeweils links die Gehäuseabdeckung im hochgeklappten und rechts im eingeklappten Zustand.Fig. 2 is a schematic representation of the housing cover with a two-part hinged cover. The figures show the housing cover on the left in the folded-up state and on the right in the folded-in state.

Ein in den Figuren durch die Gehäuseabdekkung nur teilweise dargestellter Nadeldrucker mit einem zeilenweise entlang von einer Schreibwalze 1 bewegten Nadeldruckknopf ist sowohl für den Betrieb mit Endlospapier als auch für den Betrieb mit Einzelpapier ausgerüstet. Sein Gehäuseoberteil ist ergonomisch günstig ausgestaltet und besteht aus der eigentlichen Gehäuseabdeckung 2 aus geräuschdämmendem Kunststoff mit einem angesetzten Sichtfenster 3, das einen Blick auf die Abdruckstelle gegenüber dem Druckknopf ermöglicht. In der Gehäuseabdeckung ist ein zusätzlicher Klappdeckel 4 angeordnet, der einseitig im Bereich der Vorderkante angeordnete Zapfen 5 aufweist, die in zugehörigen Führungen 6 der Gehäuseabdeckung 2 gelagert sind.A needle printer shown only partially in the figures by the housing cover with a needle push button moved line by line along by a platen roller 1 is equipped both for operation with continuous paper and for operation with single paper. Its upper housing part is ergonomically designed and consists of the actual housing cover 2 made of noise-absorbing plastic with an attached viewing window 3, which allows a view of the impression point opposite the push button. An additional hinged cover 4 is arranged in the housing cover and has pins 5 arranged on one side in the region of the front edge, which are mounted in associated guides 6 of the housing cover 2.

Bei dem in den Fig. 1, 2 rechts dargestellten, eingeklappten Zustand der Gehäuseabdeckung für den Betrieb mit Endlospapier bildet die Vorderkante des Klappdeckels 4 in Verbindung mit der Sichtscheibe 3 eine Austrittsöffnung 7 für das Endlospapier. Im ausgeklappten, hochgestellten Zustand (linker Teil der Fig. 1, 2) dient der Klappdekkel als Papieranlagefläche für Einzelblätter. Zur seitlichen Ausrichtung der Einzelblätter können auf dem Klappdeckel seitlich verstellbare Papieranschläge 8 bzw. eine zugehörige Papierausrichtskala 9 angeordnet sein. Durch diese Papieranschläge 8 wird ein lagerichtiges Einführen der Einzelblätter 10 in den Papierschacht der Druckeinrichtung erleichtert.In the folded state of the housing cover for operation with continuous paper, which is shown on the right in FIGS. 1, 2, the front edge of the hinged cover 4 forms an outlet opening 7 for the continuous paper in connection with the viewing window 3. In the unfolded, upright state (left part of Fig. 1, 2), the hinged lid serves as a paper contact surface for single sheets. For the lateral alignment of the single sheets, laterally adjustable paper stops 8 or an associated paper alignment scale 9 can be arranged on the hinged cover. These paper stops 8 facilitate the correct insertion of the single sheets 10 into the paper chute of the printing device.

Neben der in der Fig. 1 dargestellten Ausführungsform der Gehäuseabdeckung ist es noch möglich entsprechend der Fig. 2, den Klappdeckel 4 zweiteilig auszugestalten. Zu diesem Zwecke ist der Klappdeckel 4 in zwei Einzeldeckel 11 und 12 aufgeteilt, die über ein Gelenk 13 miteinander in Verbindung stehen. Der hintere Einzeldeckel 12 dient dabei im hochgeklappten Zustand des Klappdeckels als Stützelementfür die Papieranlagefläche 11.In addition to the embodiment of the housing cover shown in FIG. 1, it is still possible according to FIG. 2 to design the hinged cover 4 in two parts. For this purpose, the hinged cover 4 is divided into two individual covers 11 and 12, which are connected to one another via a joint 13. In the folded-up state of the hinged lid, the rear individual lid 12 serves as a support element for the paper contact surface 11.
