Abstract
Description
Die Erfindung betrifft eine Videokassette für Kinder mit Absicherung.The invention relates to a video cassette for children with protection.
Diese Vorkehrung dient dazu, daß Kinder bzw. Jugendliche, keine Kassetten abhören können, die nur für Erwachsene bestimmt sind.This arrangement serves to ensure that children or Adolescents who cannot tap tapes that are intended for adults only.
Man kann zwar das Videorgerät abschließen, so daß ein Abhören von Kassetten unmöglich ist, aber das will man ja nicht, sondern der Jugendliche soll die Mög lichkeit haben, für ihn bestimmte Kassetten jederzeit abhören zu können, ohne daß die Möglichkeit besteht, auch für ihn nicht geeignete Kassetten abzuspielen. You can complete the video device, so that a Eavesdropping on tapes is impossible, but that wants not one, but the youth should be able have tapes for him at any time to be able to eavesdrop without being able to also play cassettes that are not suitable for him.
Auch das Überspielen von Kassetten soll dabei nicht behindert werden.The transfer of cassettes is also not intended be hindered.
Um dies zu ermöglichen, sind die für den Jugendlichen bestimmten Kassetten mit einem Magnetkontakt ver sehen, der es ermöglicht, bei abgeschlossenem Video gerät, Kassetten abzuspielen, wogegen die nicht mit dieser Einrichtung versehen sind (für Erwachsene), nicht abgespielt werden können. Der Magnetkontakt stellt den Stromfluß her für die Kinderkassetten, während alle anderen Kassetten nur spielbar sind, bei normalem Stromkontakt des Gerätes, mittels dem zu gehörigen Schlüssel. Der Magnetkontakt hat aus reichend Platz in der freien Kammer der Kassette.To make this possible, they are for young people certain cassettes with a magnetic contact see, which makes it possible with completed video device to play tapes, but not with this facility (for adults), cannot be played. The magnetic contact creates the current flow for the children's cassettes, while all other tapes are only playable at normal current contact of the device, by means of the proper key. The magnetic contact is off sufficient space in the free chamber of the cassette.
Die Zeichnung veranschaulicht die Erfindung in bei spielsweiser Ausführung. Es zeigtThe drawing illustrates the invention in at game-like execution. It shows
Fig. 1 eine perspektivische Ansicht eines Video gerätes mit Kassette, Fig. 1 is a perspective view of a video device with cartridge
Fig. 2 eine Draufsicht auf eine Kassette, Fig. 2 is a plan view of a cassette,
Fig. 3 das Schaltsystem mit Magnetkontakt. Fig. 3 shows the switching system with magnetic contact.
Das Gerät 1 besonderer, bekannter Bauart ist mit einem üblichen Schaltschloß 2 versehen und üblichen Kassetteneinschub bzw. Kassette 3 und einer Ein schalttaste 4. Der Magnetkontakt 5 ist im Hohl raum 6 der Kassette 3 gelagert. Er ist über die Leitungen 8, 9 mit dem Schaltschloß 2 bzw. der Schalttaste 4 verbunden. Die Schalttaste 4 und die Zuleitungen 7, 8 sind auf einer Bladine 7 angeord net. Der Magnetkontakt 5 ist wie folgt zusammen gesetzt. The device 1 of special, known type is provided with a conventional switch lock 2 and the usual cassette insert or cassette 3 and a switch button 4 . The magnetic contact 5 is stored in the cavity 6 of the cassette 3 . It is connected via lines 8, 9 to switch lock 2 or switch button 4 . The switch button 4 and the feed lines 7, 8 are on a Bladine 7 angeord net. The magnetic contact 5 is composed as follows.
Zwei Metallblättchen 5 b sind von einem Glaskörper 5 umgeben. Diese Blättchen haben eine kleinen, schrägen Abstand 5 c voneinander. Die beiden Enden der Blättchen 5 b sind mit den Leitungen 8 und 9 verbunden.Two metal flakes 5 b are surrounded by a glass body 5 . These papers have a small, oblique distance 5 c from each other. The two ends of the leaflets 5 b are connected to the lines 8 and 9 .
Dieser Magnetkontakt 5, 5 b ist vorn an der Kassetten einführung 3 a angeordnet.This magnetic contact 5, 5 b is introduced at the front of the cassette 3 a .
In einer der beiden leeren Kammern 6 der Kassette 3 ist ein Magnet 5 a vorgesehen.In one of the two empty chambers 6 of the cassette 3 , a magnet 5 a is provided.
Die Kassette 3 wird in den Führungsschacht 3 a des Vi deogerätes eingeschoben. Dabei gleitet sie über den Magnetkontakt 5 und liegt im Schacht paßrecht, wenn sich der Magnet 5 a in gleicher Höhe wie der Magnetkon takt befindet und von demselben einen kleinen Abstand hat. In diesem Abstand bildet sich ein Feld, wodurch die Metallblättchen 5 b an der schrägen Trennung 5 c sich zusammenziehen und die Schaltung bewirken. Man kann jetzt die Kassette, die einen Magneten 5 a hat, abspielen.The cassette 3 is inserted deogerätes in the guide shaft 3a of the Vi. It slides over the magnetic contact 5 and is right in the shaft when the magnet 5 a is at the same height as the Magnetkon clock and a small distance from the same. At this distance, a field forms, whereby the metal flakes 5 b at the oblique separation 5 c contract and cause the circuit. You can now play the cassette, which has a magnet 5 a .
