Gegenstand vorliegender Erfindung ist ein Reinigungsgerät für bespielte und unbespielte Video-Bänder, die sich in einer Video-Cassette befinden.The present invention is a cleaning device for recorded and blank video tapes that are in a video cassette.

Da Video-Bänder Staub annehmen und dieser bei der Aufzeichnung und späteren Wiedergabe als Störung = Bildaussetzer (weiße Punkte oder Striche) auf dem Fernsehschirm sichtbar wird, setzt sich die Erfindung zum Ziel die zur Aufnahme oder Wiedergabe vorgesehenen Video-Cassetten vorher von Staub zu reinigen, was bisher noch nicht praktiziert wurde.Since video tapes take on dust and this when recording and later playback as disturbance = picture dropouts (white dots or lines) becomes visible on the television screen, the aim of the invention is to record or playback provided video cassettes to be cleaned of dust beforehand, which was previously done has not yet been practiced.

Bisher wurden mit einem Reinigungsband die Köpfe (Aufnahme-und Wiedergabekopf) des Videorecorders gereinigt.So far, the heads (recording and playback head) have been cleaned with a cleaning tape. of the video recorder cleaned.

Es dürfte einleuchtend sein, daß mit dem bisherigen Ropf-Reinigungsband zwar die Köpfe des Videorecorders gereinigt wurden, aber das verschmutzte Video-Band nach der Tonkopfreinigung wieder abgespielt wurde.It should be obvious that with the previous Ropf cleaning tape Although the heads of the video recorder were cleaned, the video tape was dirty was played again after cleaning the tape head.

Jede Video-Cassette Fig. 1 hat einen schwenkbaren Sicherungsdeckel 1, der durch Drücken eines Sicherungsstiftes 2 entriegelt und hochgehoben werden kann. Nach Hochheben des Sicherungsdeckels 1 wird das Video-Band freigelegt. Das Video-Band läuft bei der Aufnahme und Wiedergabe von rechts nach links vor zwei nach vorn ausgebildeten Führungstischen 4, die an der Ober- und Unterkante Führungsleisten 5 + 6 haben, entlang. Nach hochheben des Sicherungsdeckels 1 wird die Video-Cassette in das Gehäuse des Reinigungsgerätes 13 Fig. 2 gelegt. Zwei Antriebsnoppen 7 und ein Entriegelungstift 8 der eine Bandsperre in der Video-Cassette löst, greifen von unten in die entsprechenden Öffnungen der Video-Cassette.Each video cassette Fig. 1 has a pivotable safety cover 1, which can be unlocked and lifted up by pressing a locking pin 2 can. After lifting the safety cover 1, the video tape is exposed. That Video tape runs from right to left in front of two during recording and playback forward-trained guide tables 4, the guide strips on the upper and lower edge 5 + 6 have along. After lifting the safety cover 1, the video cassette becomes placed in the housing of the cleaning device 13 Fig. 2. Two drive knobs 7 and an unlocking pin 8 which releases a tape lock in the video cassette, grab from below into the corresponding openings in the video cassette.

Die Leiste 9 hält den Sicherungsdeckel 1 hoch. Das freigelegte, sichtbare Video-Band wird vor die beiden Filzstreifen lo gedrückt. Die Filzstreifen lo sind so ausgelegt, daß sie zwischen die Führungsleisten 5 + 6 passen. Der durch die Filzstreifen lo auf das Video-Band erfolrierlcie Druck, wird durch die hinter dem Band befind] ichen Führungs. .rche 4 aufgefangen.The bar 9 holds the fuse cover 1 up. The exposed, visible Video tape is pressed in front of the two felt strips lo. The felt strips are lo designed so that they fit between the guide rails 5 + 6. The one through the felt strips The pressure on the video tape is successful because of the pressure behind the tape. ichen leadership. .rche 4 caught.

Die auswchselbarcn Filz streifen lo befinden sich in Führungsschienen 11.The replaceable felt strips are located in guide rails 11.

Bei stark verschmutzten Video-Bändern wird der rechte Filzstreifen lo durch die Öffnung 12 mit einer handelsüblichen Reinigungsflüssigkeit Alkohol mit Freon TF (auf dem Markt zur Reinigung der Tonköpfe) getränkt, sodaß das zu reinigende Band erst über den feuchten Filzstreifen lo läuft und dann über den trockenen.If the video tapes are very dirty, the felt strip on the right will be lo through the opening 12 with a commercially available cleaning liquid alcohol soaked with Freon TF (on the market for cleaning the tape heads) so that the to be cleaned The tape first runs over the damp felt strip and then over the dry one.
