Description

Tonwiedergabegerät mit Anzeigevorrichtung für den Abnutzungsgrad der Abtastnadel Die Erfindung betrifft ein Tonwiedergabegerät zur Abtastung von Tonträgern mit mechanisch aufgebrachter Schallschrift, bei dem eine Anzeigevorrichtung für den Abnutzungsgrad der Abtastnadel vorgesehen ist.Sound reproduction device with display device for the degree of wear and tear of the Scanning needle The invention relates to a sound reproduction device for scanning sound carriers with mechanically applied sound writing, in which a display device for the degree of wear of the stylus is provided.

Die üblicherweise aus Saphir oder Diamant bestehenden Abtastnadeln von solchen Tonwiedergabegeräten unterliegen einer Abnutzung. übersteigt diese Abnutzung ein bestimmtes Maß, so werden die Tonträger bei der Abtastung in Mitleidenschaft gezogen, was insbesondere bei mit empfindlichen Mikrorillen beschrifteten Langspielplatten vermieden werden sollte, da sonst diese Schallplatten schnell unbrauchbar werden.The stylus, usually made of sapphire or diamond of such sound reproducers are subject to wear and tear. exceeds this wear and tear a certain amount, the sound carriers are affected by the scanning pulled, which is especially true for long-playing records labeled with sensitive micro-grooves should be avoided, otherwise these records will quickly become unusable.

Es ist bereits bekannt, mit dem Plattenspieler ein Zählwerk zu verbinden, das die Betriebsstunden des Plattenspielers angibt. Bei einem bestimmten Anzeigewert, der von dem Material abhängt, aus dem die Abtastnadel hergestellt ist, soll die Abtastnadel gegen eine neue ausgetauscht werden.It is already known to connect a counter to the turntable, which indicates the hours of operation of the turntable. At a certain display value, which depends on the material from which the stylus is made, the The stylus can be exchanged for a new one.

Es ist auch bereits vorgeschlagen worden, den Betriebszeitzähler dazu zu benutzen, nach Ablauf einer vorbestimmten Zeit den Motorschalter des Plattenspielers zu öffnen, den Plattenspieler also stillzusetzen.It has also already been proposed to add the operating time counter to use, after a predetermined time, the motor switch of the turntable to open, so shut down the turntable.

Beide Einrichtungen haben den Nachteil, daß sie die Zeiten, in denen der Tonarm vom Plattenteller abgehoben ist, mitzählen, wodurch bezüglich der Benutzungszeit ein unter Umständen völlig falsches Bild entsteht.Both facilities have the disadvantage that they have the times when the tonearm is lifted off the turntable, counting, which affects the usage time a possibly completely wrong picture emerges.

Der Erfindung liegt die Aufgabe zugrunde, die Anzeigevorrichtung so anzuordnen, daß sie einen Wert anzeigt, der nur von der tatsächlichen Benutzung der Abtastnadel abhängt. Die Erfindung besteht darin, daß die als Rechengetriebe ausgebildete Anzeigevorrichtung den von der Abtastnadel in den Schallrillen zurückgelegten Weg ermittelt.The invention is based on the object of the display device so to order that it displays a value that is only dependent on actual use the stylus depends. The invention consists in that as a computing gear formed display device covered by the stylus in the sound grooves Path determined.

Eine solche Anzeigevorrichtung kann auf mechanischem, magnetischem, elektrischem oder optischem Wege arbeiten.Such a display device can be based on mechanical, magnetic, work electrically or optically.
