Abstract
Innerhalb der Gehäuseabdeckung für einen Nadeldrucker für den Betrieb mit Endlos- und Einzelpapier ist ein zusätzlicher, hochstellbarer, den Papierschacht der Druckeinrichtung abdeckender Klappdeckel angeordnet, der im ausgeklappten Zustand als Papieranlagefläche für Einzelpapier dient. Der Klappdeckel kann aus zwei Einzeldeckel bestehen, die über ein Gelenk verbunden sind.Inside the housing cover for a dot-matrix printer for operation with continuous and single paper, an additional, fold-up cover, which covers the paper chute of the printing device, is arranged, which serves as a paper contact surface for single paper in the unfolded state. The hinged lid can consist of two individual lids which are connected via a hinge.
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 Datendrucker 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 hard copy 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.
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 such that that, with optimum noise insulation, it enables easy loading of single sheets in addition to operation with continuous paper.
Diese Aufgabe wird bei einer Gehäuseabdeckung 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 according to the characterizing part of patent claim 1. Further advantageous embodiments are characterized in the subclaims.
Dadurch daß innerhalb der Gehäuseabdeckung ein zusätzlicher hochstellbarer den Papierschacht der Druckeinrichtung abdeckender Klappdeckel angeordnet ist, der im hochgeklappten Zustand als Papieranlagefläche für Einzelblätter dient, wird das Einlegen von Einzelblättern wesentlich erleichtert. Trotzdem ist durch den Klappdeckel beim Betrieb mit Endlospapier eine optimale Geräuschdämmung garantiert. Auf dem Klappdeckel angeordnete verstellbare Papieranschläge mit zugehöriger Papierausrichtsskala erleichtern die Justierung des Einzelblattes beim Einlegen.The fact that an additional fold-up cover, which can be raised and covers the paper chute of the printing device, is arranged within the housing cover and, when folded up, serves as a paper contact surface for single sheets, the insertion of single sheets is made considerably easier. Nevertheless, the hinged lid guarantees optimal noise insulation when operating with continuous paper. 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 zeigen
- Fig. 1 eine schematische Darstellung der erfindungsgemäßen Gehäuseabdeckung mit einem einteiligen Klappdeckel und
- 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. 1 is a schematic representation of the housing cover according to the invention with a one-piece hinged cover and
- 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 Gehäuseabdeckung nur teilweise dargestellter Nadeldrucker mit einem zeilenweise entlang von einer Schreibwalze 1 bewegten Nadeldruckkopf 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 geräuschdämmenden Kunststoff mit einem angesetzten Sichtfenster 3, das einen Blick auf die Abdruckstelle gegenüber dem Druckkopf 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 dot matrix printer shown only partially in the figures by the housing cover with a line by line The needle print head moved along by a platen roller 1 is equipped both for the operation with continuous paper and for the operation with single paper. Its upper housing part is ergonomically designed and consists of the
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 Klappdeckel 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
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 Stützelement für 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
