Description

Die Erfindung betrifft eine Farbbandkassette der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The invention relates to an ink ribbon cassette of the type specified in the preamble of claim 1.

Strichziehvorrichtungen an Schreibmaschinen zum Ziehen von waagerechten und senkrechten Linien sind schon mehrfach bekannt. Die Tatsache, daß sie in der Praxis kaum anzutreffen sind, dürfte genügend beweisen, daß sie sich nicht bewährt haben bwz. den Schreibvorgang zu sehr behinderten.Line drawing devices on typewriters for drawing horizontal and vertical lines are already known several times. The fact that they can hardly be found in practice should prove enough that they have not proven themselves. the writing process too disabled.

Durch die deutsche Patentschrift DE-C-891 271 ist eine Haltervorrichtung an Schreibmaschinen zur Aufnahme einer mit Gewinde versehenen Kugelschreiberpatrone bekannt, bei der auf die Zeilenbleche rechts oder links neben dem Typenführungskopf ein mit Gewinde versehener Halter zur Aufnahme der Schreibpatrone mittels einer Klemme festklemmbar angeordnet ist. Hierbei weist das aus Kunststoff bestehende Zeilenblech anstelle eines Einsteckloches eine Gewindehülse zur Aufnahme der Schreibpatrone auf. Eine derartige Anordnung stört den Schreibvorgang insbesondere bei den Maschinen, bei denen der Druckkopf auf einem längs des Aufzeichnungsträgers bewegbaren Schlitten angeordnet ist. Auch würde der Austausch der Kugelschreiberpatronen eine gewisse Geschicklichkeit von der Bedienungsperson der Maschine abverlangen.German patent specification DE-C-891 271 discloses a holder device on typewriters for receiving a threaded ballpoint cartridge, in which a threaded holder for receiving the writing cartridge is arranged by means of a clamp on the row plates to the right or left of the type guide head . Here, the row plate made of plastic has a threaded sleeve instead of an insertion hole for receiving the writing cartridge. Such an arrangement interferes with the writing process, in particular in the case of machines in which the print head is arranged on a carriage which can be moved along the record carrier. The replacement of the ballpoint pen cartridges would also require a certain skill from the operator of the machine.

Durch das US-Patent US-A-4,259,025 ist ein Typenraddruckwerk bekannt, das auch für einen Plotterbetrieb eingesetzt werden kann. Zu diesem Zweck wird die Farbbandkassette gegen eine Kassette mit einem darin enthaltenen verschiebbaren Farbstift ausgetauscht. Diese Plottereinrichtung kann in einer normalen Farbbandkassette nicht untergebracht werden, ohne daß der Farbbandtransport gestört wird. Wenn bei einem normalen Schreibbetrieb Linien zu ziehen sind, dann ist ein Wechseln der Kassetten erforderlich. Dieses führt zu einer erheblichen Reduzierung der Schreibleistung.A type wheel printing unit is known from US Pat. No. 4,259,025, which can also be used for a plotter operation. For this purpose, the ribbon cassette is exchanged for a cassette with a displaceable colored pencil contained therein. This plotter device cannot be accommodated in a normal ribbon cassette without disturbing the ribbon transport. If lines are closed during normal write operation the cassettes have to be changed. This leads to a significant reduction in writing performance.

Weiterhin offenbart die US-A-4,249,025 die Möglichkeit, den Farbstift auch zusätzlich zum Farbband vorzusehen, wobei in diesem Fall der Stift oberhalb des Farbbandes anzuordnen ist. Hierdurch ist zwar ein Herausnehmen der Farbbandkassette zum Plottern nicht erforderlich, aber zum Austauschen der Farbbandkassette stört der Farbstift.Furthermore, US-A-4,249,025 discloses the possibility of also providing the colored pencil in addition to the ribbon, in which case the pencil is to be arranged above the ribbon. As a result, it is not necessary to remove the ribbon cassette for plottering, but the colored pencil interferes with the replacement of the ribbon cassette.

Der Erfindung liegt die Aufgabe zugrunde, eine Farbbandkassette mit einem zusätzlichen Farbstift zu schaffen, die gegenüber dem Stand der Technik eine verbesserte Plottereinrichtung aufweist, derart, daß Linienzüge in horizontaler, vertikaler oder anderer Richtung auf einfachste Weise erzeugbar sind. Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichnete Erfindung gelöst.The invention has for its object to provide an ink ribbon cassette with an additional colored pen, which has an improved plotter device compared to the prior art, such that lines in the horizontal, vertical or other direction can be generated in the simplest way. This object is achieved by the invention characterized in claim 1.

Die Farbbandkassette weist ein Verschiebeelement mit einem Farbstift auf, das über eine hieran befindliche Handhabe aus einer Außereingriffsstellung in eine Bereitschaftsstellung verschiebbar angeordnet ist. Der Farbstift kann hierbei dort an der Kassette angebracht werden, wo der Schreibvorgang nicht gestört wird. Auch kann der Farbstift z. B. durch Herausnahme der Farbbandkassette leicht ausgewechselt werden. Auch kann bei einem Kassettenwechsel, wenn das Farbband verbraucht ist, der Farbstift aus dieser Kassette herausgenommen und in eine neue Kassette eingesetzt werden. Die Farbbandkassette mit dem Farbstift ermöglicht eine einfache Erzeugung von Linienzügen in horizontaler, vertikaler oder auch in jeder anderen Richtung.The ribbon cassette has a sliding element with a colored pencil, which is arranged so that it can be moved from a disengaged position to a ready position by means of a handle located thereon. The colored pencil can be attached to the cassette where the writing process is not disturbed. Also, the colored pencil z. B. can be easily replaced by removing the ribbon cassette. When changing the cassette, when the ink ribbon is used up, the colored pencil can be removed from this cassette and inserted into a new cassette. The ribbon cassette with the colored pencil enables you to easily create lines in horizontal, vertical or in any other direction.

Die Farbbandkassette mit dem verschiebbaren Farbstift ist derart weiterzubilden, daß der Farbstift mittels eines Tastensignals oder im On-Line-Betrieb mittels Software ein- und ausschaltbar ist. Dieses wird vorteilhaft dadurch gelöst, daß mit dem Aufsetzen der Farbbandkassetten auf die Aufnahmevorrichtung des längs des Aufzeichnungsträgers bewegbaren Schlittens die verschiebbaren Halterungen mit den Farbstiften automatisch mit elektrisch ansteuerbaren Antriebsgliedern in der Aufnahmevorrichtung gekuppelt werden. Die Schreibstifte sind durch mit den Antriebsgliedern in Wirkverbindung stehende Elektromagnete mittels Tastensignale oder im On-Line-Betrieb mittels Software in die Arbeitsstellung bring- und nach Erregung der Elektromagnete durch Federkraft wieder in die Ausgangsstellungen rückstellbar.The ribbon cassette with the displaceable colored pencil is to be developed in such a way that the colored pencil can be switched on and off by means of a key signal or in online operation using software. This is advantageously achieved in that, when the ink ribbon cassettes are placed on the receiving device of the carriage which can be moved along the recording medium, the displaceable holders with the colored pencils are automatically coupled to electrically controllable drive members in the receiving device. The pens can be brought into the working position by means of electromagnets in operative connection with the drive elements by means of key signals or in online operation by means of software, and can be reset to the starting positions after excitation of the electromagnets by spring force.

Weitere vorteilhafte Ausgestaltungen des Erfindungsgegenstandes sind den weiteren Unteransprüchen zu entnehmen.Further advantageous refinements of the subject matter of the invention can be found in the further subclaims.

  • Figuren 5 und 6 eine weitere Ausführungsform für die Halterung.
The invention is described in more detail below using an exemplary embodiment. It shows
  • FIG. 1 shows an ink ribbon cassette in the receiving device of the machine,
  • FIG. 2 a holder with the colored pencil,
  • FIG. 3 shows a detail from FIG. 1, the holder with the colored pencil being in the inoperative position,
  • Figure 4 shows the bracket of Figure 3 in the working position and the
  • Figures 5 and 6 another embodiment for the bracket.

In der Figur 1 ist ein längs eines Aufzeichnungsträgers 1 auf Achsen 2, 3 bewegbarer Schlitten 4 mit einer Aufnahmevorrichtung 5 für die Farbbandkassette 6 dargestellt. Der Aufzeichnungsträger 1 wird durch eine Papierwalze 7 in bekannter Weise transportiert. Das Farbbandkassettengehäuse der Farbbandkassette 6 besteht aus einem topfförmigen Bodenteil 8 und einem ebenförmig ausgebildeten Deckel 9. Das Farbband 10 wird mittels einer Transportvorrichtung von einer Vorratsspule 11 abgewickelt, durch eine Austrittsöffnung 13 zu der Druckstation herausgeführt und dann über eine Eintrittsöffnung 14 zu einer Aufwickelspule 12 geführt. Die Farbbandkassette 6 weist eine Aufnahmevorrichtung 15 für einen Farbstift 16 auf, der z. B. aus einemFaserstift oder einer Kugelschreibermine bestehen kann und in einer Endstellung an dem Aufzeichnungsträger 1 zur Erzeugung von Linien in vertikaler, horizontaler oder in sonstiger Richtung federnd anliegt und zum Außerbetriebsetzen in eine andere Endstellung beweg- und verrastbar angeordnet ist. Der Farbstift 16 ist in einer Halterung 17 auswechselbar befestigt, die in eine Aufnahmeöffnung 18 des Kassettengehäuses einsteck- und in dieser in die beiden Endstellungen verschiebbar angeordnet ist.1 shows a carriage 4 which can be moved along a recording medium 1 on axes 2, 3 and has a holding device 5 for the ink ribbon cassette 6. The record carrier 1 is transported by a paper roller 7 in a known manner. The ribbon cassette housing of the ribbon cassette 6 consists of a pot-shaped base part 8 and a flat lid 9. The ribbon 10 is unwound from a supply spool 11 by means of a transport device, led out through an outlet opening 13 to the printing station and then guided via an inlet opening 14 to a winding spool 12 . The ribbon cassette 6 has a receiving device 15 for a colored pencil 16 which, for. B. may consist of a fiber pen or a ballpoint pen refill and resiliently in one end position on the recording medium 1 for generating lines in the vertical, horizontal or in any other direction and is arranged so as to be movable and lockable for decommissioning in another end position. The colored pencil 16 is exchangeably fastened in a holder 17 which is inserted into a receiving opening 18 of the cassette housing and is displaceably arranged in the two end positions thereof.

Die Figur 2 zeigt die Halterung 17 mit dem Farbstift 16 vor dem Einsetzen in die Aufnahmeöffnung 18 des Kassettengehäuses. Diese Halterung 17 besteht aus einem gespritzten Kunststoffteil, das an dem aus dem Kassettengehäuse herausragenden Ende 19 den Farbstift 16 und an dem anderen Ende 20 einen in die Aufnahmeöffnung 18 einschiebbaren Schaltarm 21 aufweist. Dieser Schaltarm 21 ist zur Verschieberichtung der Halterung 17 als Formfeder senkrecht federnd ausgebildet und mit Rastnasen 22, 23 versehen, die in Rastausnehmungen 24, 25 auf der Oberseite 26 des Kassettengehäuses für die beiden Endstellungen einrastbar sind. Die Rastausnehmungen 24, 25 sind vorzugsweise in dem ebenförmig ausgebildeten Deckel 9 des Kassettengehäuses angeordnet, wobei der Deckel 9 gleichzeitig eine Wand der Aufnahmeöffnung 18 bildet.FIG. 2 shows the holder 17 with the colored pencil 16 before it is inserted into the receiving opening 18 of the cassette housing. This bracket 17 consists of an injection molded plastic part that the end 19 protruding from the cassette housing has the colored pencil 16 and at the other end 20 a switching arm 21 which can be inserted into the receiving opening 18. This switching arm 21 is designed to be perpendicular to the direction of displacement of the holder 17 as a shaped spring and is provided with locking lugs 22, 23 which can be latched into locking recesses 24, 25 on the top 26 of the cassette housing for the two end positions. The locking recesses 24, 25 are preferably arranged in the flat-shaped cover 9 of the cassette housing, the cover 9 simultaneously forming a wall of the receiving opening 18.

Die Rastnase 23 ist übrigens als Schiebegriff derart ausgebildet, daß die Halterung 17 durch Fingerkraft aus der einen in die andere Endstellung bewegbar ist. Die Rastnase 23 wird beim Bewegen der Halterung 17 in die beiden Endlagen in der als Schiebeschlitz dienenden Rastausnehmung 25 geführt, wobei die Rastnase 23 in der Bereitschaftsstellung des Farbstiftes 16 mit einer geraden Kante 33 an der Endkante 28 und in der anderen Endstellung mit einer abgerundeten Kante 34 an der anderen Endkante 29 der Rastausnehmung 25 federnd anliegt. Die zweite Rastnase 22 wird in der Außerbetriebsstellung des Farbstiftes 16 mit einer geraden Kante 35 gegen die Endkante 28 der Rastausnehmung 25 gedrückt.Incidentally, the locking lug 23 is designed as a push handle such that the holder 17 can be moved from one end position to the other by finger force. The detent 23 is guided when the holder 17 is moved into the two end positions in the detent recess 25 serving as a sliding slot, the detent 23 in the ready position of the colored pencil 16 with a straight edge 33 at the end edge 28 and in the other end position with a rounded edge 34 rests resiliently on the other end edge 29 of the latching recess 25. In the inoperative position of the colored pencil 16, the second locking lug 22 is pressed with a straight edge 35 against the end edge 28 of the locking recess 25.

Die zweite Rastnase 22 weist an der Unterseite eine Schrägfläche bis 30 als Formkante auf, über die die Halterung 17 mit dem Farbstift 16 beim Einrasten der zweiten Rastnase 22 in die Rastausnehmung 24 gegen den Aufzeichnungsträger 1 federnd andrückbar ist. Hierdurch wird eine Federkraft in Schieberichtung der Halterung 17 gegen den Aufzeichnungsträger 1 auf einfachste Weise erzeugt. Übrigens ist das den Farbstift 16 tragende Ende 19 der Halterung 17 als Führungsteil mit Führungsflächen 31, 32 ausgebildet. Diese Führungsflächen 31, 32 sind in der Aufnahmeöffnung 18 verschiebbar gelagert.The second locking lug 22 has on the underside an inclined surface up to 30 as a shaped edge, via which the holder 17 with the colored pencil 16 can be pressed resiliently against the recording medium 1 when the second locking lug 22 engages in the locking recess 24. As a result, a spring force in the sliding direction of the holder 17 against the recording medium 1 is generated in the simplest way. Incidentally, the end 19 of the holder 17 carrying the colored pencil 16 is designed as a guide part with guide surfaces 31, 32. These guide surfaces 31, 32 are slidably mounted in the receiving opening 18.

In der Figur 3 ist die Halterung 17 in Außerbetriebsstellung dargestellt. Soll die Halterung 17 nun in die Bereitschaftsstellung gebracht werden, dann wird die Rastnase 23 durch Fingerkraft zunächst in Pfeilrichtung 36 derart beaufschlagt, daß die Rastnase 22 außer Eingriff mit der Endkante 28 der Rastausnehmung 25 gelangt. Nach diesem Entrasten wird die Rastnase 23 durch Fingerkraft in Pfeilrichtung 37 soweit nach oben bewegt, bis die Nase 22 in die Rastausnehmung 24 einrastet. Bei diesem Einrasten wird über die als Formkante dienende Schrägfläche 30 eine gleichmäßige federnde Andruckkraft des Farbstiftes 16 gegen den Aufzeichnungsträger 1 erzeugt, wodurch ein stets gleichbleibendes Linieren ermöglicht wird.In Figure 3, the bracket 17 is shown in the inoperative position. If the holder 17 is now to be brought into the ready position, then the locking lug 23 is initially acted upon by finger force in the direction of the arrow 36 in such a way that the locking lug 22 comes out of engagement with the end edge 28 of the locking recess 25. After this unlatching, the locking lug 23 is moved upwards by finger force in the direction of the arrow 37 until the lug 22 engages in the locking recess 24. During this engagement, a uniform, resilient pressing force of the colored pencil 16 against the recording medium 1 is generated via the inclined surface 30 which serves as the shape edge, whereby a constant ruling is made possible.

Die Rückstellung der Halterung 17 aus der Bereitschaftsstellung gemäß Figur 4 in die Außerbetriebsstellung gemäß Figur 3 erfolgt dadurch, daß die Rastnase 23 zunächst wieder in Pfeilrichtung 36 und dann in Pfeilrichtung 38 nach unten in der Rastausnehmung 25 soweit verschoben wird, bis die Rastnase 22 auch in der Rastausnehmung 25 einrastet. Hiernach liegt die gerade Kante 35 der Rastnase 22 wieder an der Endkante 28 in der Rastausnehmung 25 an.The holder 17 is reset from the ready position according to FIG. 4 to the inoperative position according to FIG. 3 in that the locking lug 23 is first shifted again in the direction of the arrow 36 and then in the direction of the arrow 38 downwards in the locking recess 25 until the locking lug 22 also in the locking recess 25 engages. Thereafter, the straight edge 35 of the locking lug 22 rests against the end edge 28 in the locking recess 25.

Die Figur 5 zeigt die Halterung 17 mit dem Farbstift 16 vor dem Einsetzen in die Aufnahmeöffnung 18 des Kassettengehäuses. Diese Halterung 17 besteht aus einem gespritzten Kunststoffteil, das an dem aus dem Kassettengehäuse herausragenden Ende 190 den Farbstift 16 und an dem anderen Ende 200 ein in die Aufnahmeöffnung 18 einschiebbares Lagerteil 210 aufweist. Die Halterung 17 ist einerseits mit dem zylindrisch ausgebildeten Lagerteil 210 in einer hinteren Lagerbohrung 220 und mit einem Lagerzapfen 230 in einer vorderen Lagerbohrung 240 in der Aufnahmeöffnung 18 verschiebbar gelagert. Weiterhin befindet sich in der Aufnahmeöffnung 18 ein vorstehender, angespritzter Federarm 250, durch den die Halterung 17 mit einem Bund 260 an dem Lagerbock 270 mit der Lagerbohrung 240 in der Ausgangsstellung federnd in Anlage haltbar ist. Die Halterungen 17 weisen Kupplungsteile auf, die beim Aufsetzen der Farbbandkassetten 6 auf die Aufnahmevorrichtung 5 des Schlittens 4 mit auf diesem gelagerten Antriebsgliedern kuppelbar sind. Zu diesem Zweck weisen die verschiebbaren Halterungen 17 Kupplungsschlitze 280 zum formschlüssigen Kuppeln mit durch Öffnungen 290 in dem Boden 8 der Kassette 6 durchsteckbaren Kupplungsarmen 300 von Antriebsgliedern auf. Diese Kupplungsarme 300 sind an freien Enden von Antriebshebeln 310 angeordnet, welche durch die Antriebsglieder zum Ineingriffbringen der Farbstifte 16 mit dem Aufzeichnungsträger 1 in die eine Endstellung bring- und durch eine Rückstellfeder 320 wieder in die Ausgangsstellungen rückstellbar sind. Die Antriebshebel 310 sind z. B. als Anker für Elektromagnete 330 ausgebildet und werden bei Erregung dieser Elektromagnete 330 um den Lagerarm 340 im Gegenuhrzeigersinn gegen die Kraft der Rückstellfeder 320 verschwenkt. Hierdurch wird eine einfache Antriebsmöglichkeit zum Verschieben der Halterungen 17 mit den Farbstiften 16 geschaffen, wobei das Kuppeln bzw. Entkuppeln automatisch mit dem Aufsetzen bzw. mit dem Abnehmen der Farbbandkassette auf die bzw. von der Aufnahmevorrichtung 5 erfolgt. Da die Antriebsglieder also in der Maschine verbleiben, werden die Farbbandkassetten mit den Farbstiften gegenüber den normalen Farbbandkassetten nur unwesentlich teurer. Bei verbrauchter Farbbandkassette sind die Farbstifte leicht in die neue Kassette übernehmbar.FIG. 5 shows the holder 17 with the colored pencil 16 before it is inserted into the receiving opening 18 of the cassette housing. This holder 17 consists of an injection-molded plastic part which has the colored pencil 16 on the end 190 protruding from the cassette housing and a bearing part 210 which can be inserted into the receiving opening 18 at the other end 200. The holder 17 is on the one hand slidably mounted with the cylindrical bearing part 210 in a rear bearing bore 220 and with a bearing pin 230 in a front bearing bore 240 in the receiving opening 18. Furthermore, a projecting, molded spring arm 250 is located in the receiving opening 18, through which the holder 17 with a collar 260 on the bearing block 270 with the bearing bore 240 resiliently in contact in the starting position is durable. The brackets 17 have coupling parts which, when the ink ribbon cassettes 6 are placed on the receiving device 5 of the carriage 4, can be coupled to drive members mounted thereon. For this purpose, the displaceable holders 17 have coupling slots 280 for form-fitting coupling with coupling arms 300 of drive elements which can be pushed through openings 290 in the base 8 of the cassette 6. These coupling arms 300 are arranged at free ends of drive levers 310, which can be brought into one end position by the drive elements for engaging the colored pencils 16 with the recording medium 1 and can be reset to the starting positions by a return spring 320. The drive lever 310 are e.g. B. formed as an armature for electromagnets 330 and are pivoted upon excitation of these electromagnets 330 around the bearing arm 340 in a counterclockwise direction against the force of the return spring 320. This creates a simple drive option for moving the holders 17 with the colored pencils 16, the coupling or uncoupling taking place automatically when the ribbon cassette is placed or removed from the receiving device 5. Since the drive elements remain in the machine, the ribbon cartridges with the colored pencils are only insignificantly more expensive than the normal ribbon cartridges. If the ribbon cassette is used up, the colored pencils can easily be transferred to the new cassette.

Zur Erzeugung von Linien oder linienförmigen Kurven wird die Halterung 17 mit dem gewünschten Farbstift 16 durch den im Druckwerk angeordneten Elektromagneten 330 in Verbindung mit einem Tastensignal oder im On-Line-Betrieb mittels Software in die Arbeitsstellung gebracht. Die Anzugskraft dieses Elektromagneten 330 ist in Verbindung mit dem Federarm 250 so ausgelegt, daß ein gut sichtbarer Linienzug auf dem Aufzeichnungsträger 1 erzeugbar ist. Nach Entregung des Elektromagneten 330 werden der als Anker ausgebildete Antriebshebel 310 und damit die Halterung 17 durch die Rückstellkräfte der Federn 250 und 320 in die Ausgangslage zurückgestellt. Hierdurch wird der Farbstift 16 wieder außer Eingriff mit dem Aufzeichnungsträger 1 gebracht.To generate lines or line-shaped curves, the holder 17 is brought into the working position with the desired colored pencil 16 by the electromagnet 330 arranged in the printing unit in connection with a key signal or in online operation by means of software. The tightening force of this electromagnet 330 is designed in connection with the spring arm 250 so that a clearly visible line can be generated on the recording medium 1. After de-energization of the electromagnet 330, the drive lever 310 designed as an armature and thus the holder 17 are returned to the starting position by the restoring forces of the springs 250 and 320. As a result, the colored pencil 16 is brought out of engagement with the recording medium 1 again.
