Abstract

Hitherto, such receiving devices, for example VHS video recorders by JVC, type D66, have been made of a number of sheet metal parts and a number of riveted-on bolts. Because of the required accuracy in production and operational reliability, this was expensive. The present invention had the object of providing an equally good but more inexpensive solution. The solution provides a single-part receiving device which is preferably injection moulded. Luran 378 P G7, in particular, is suitable for this purpose. This receiving device is used by being mounted on the drive mechanism of a video recorder and ensures proper positioning of an inserted tape cassette. <IMAGE>

Description

Die Erfindung betrifft eine Aufnahme-Vorrichtung für eine Bandkassette in einem Video-Recorder gemäß dem Oberbegriff des ersten Anspruchs.The invention relates to a recording device for a Tape cassette in a video recorder according to the generic term of the first claim.

Es ist üblich bei Video-Recordern, daß eine Aufnahme-Vorrich­ tung auf dem Laufwerk vorgesehen ist, die dafür sorgt, daß eine eingelegte Bandkassette in eine genau definierte Position auf dem Laufwerk gelangt.It is common with video recorders that a recording device device is provided on the drive, which ensures that an inserted tape cassette into a precisely defined one Position reached on the drive.

Bisherige Aufnahme-Vorrichtungen, beispielsweise bei dem VHS Video-Recorder von JVC, Type D 66, waren relativ kompli­ ziert aus mehreren Blechteilen zusammengesetzt und besaßen einige angenietete Bolzen, die für die positionierte Halte­ rung auf dem Laufwerk erforderlich sind. Die Fertigungskosten dieser Aufnahme waren wegen der erforderlichen Fertigungsge­ nauigkeit und gleichbleibenden Funktionssicherheit zu hoch.Previous recording devices, for example in the VHS video recorders from JVC, Type D 66, were relatively complicated adorned from several sheet metal parts and owned some riveted bolts that are used for holding the positioned drive are required. The manufacturing cost this recording were due to the required manufacturing ge accuracy and constant functional reliability high.

Der Erfindung lag deshalb die Aufgabe zu grunde, bei gleicher Funktionssicherheit eine Aufnahme-Vorrichtung zu entwickeln, die erheblich billiger herstellbar ist und nicht mehr eine Montage von mehreren Bauteilen in der Fertigung erfordert. Diese Aufgabe wird nach der Erfindung durch die im Anspruch 1 aufgeführten Merkmale gelöst. Weitere Einzelheiten und Weiterbildungen sind den Unteransprüchen und der Beschrei­ bung eines Ausführungsbeispiels zu entnehmen.The object of the invention was therefore based on the same Reliability to develop a recording device, which is much cheaper to produce and nothing more an assembly of several components in production requires.  This object is achieved according to the invention by the in claim 1 listed features solved. More details and Further training is the subclaims and the description exercise of an embodiment.

Vorteilhafterweise ist es nach der Erfindung möglich, die Aufnahme-Vorrichtung einteilig herzustellen. Das kann vorzugsweise durch Spritzen mit geeignetem Werkstoff, wie z.B. mit Luran 378 P G7, geschehen.According to the invention, it is advantageously possible to manufacture the recording device in one piece. That can preferably by spraying with a suitable material, such as. with Luran 378 P G7.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt, die eine Aufnahme-Vorrichtung in vier Ansichten zeigt. Die beiden Seitenteile 1, 2 das Bodenteil 3 undAn embodiment of the invention is shown in the drawing, which shows a recording device in four views. The two side parts 1 , 2, the bottom part 3 and

das Oberteil 4 weisen eine Reihe von verschieden großen runden Löchern auf. Diese und die angeformten runden Bolzen und Zapfen, die nach außen ragen, dienen der Halterung der Aufnahme-Vorrichtung, ihrer funktionsgerechten Positio­ nierung und koopieren mit entsprechenden Teilen auf dem Laufwerk des Video-Recorders, der nicht gezeigt ist.the upper part 4 have a number of different sized round holes. This and the molded round bolts and pins, which protrude outwards, serve to hold the recording device, its functional positioning and cooperate with corresponding parts on the drive of the video recorder, which is not shown.

Auf der Innenseite des Bodenteils 3 ist eine Öffnung 5 für einen Bandsensor im Laufwerk vorgesehen, die mit einer entsprechenden Öffnung einer eingeschobenen Kassette zusammen­ arbeitet und es ermöglicht, daß dem Benutzer des Video-Re­ corders das ordnungsgemäße Verhandensein des Bandes angezeigt wird. Vor und nach dieser Öffnung 5 befinden sich in Kasset­ ten-Bewegungsrichtung je eine fluchtende kurze Rippe 6, 7 die mit entsprechenden Führungsmitteln der Kassette zusammen­ wirken.On the inside of the bottom part 3 there is an opening 5 for a tape sensor in the drive, which works together with a corresponding opening of an inserted cassette and enables the user of the video recorder to be shown that the tape is properly negotiated. Before and after this opening 5 are each in alignment in the cassette ten movement direction, a short rib 6 , 7 which cooperate with corresponding guide means of the cassette.
