 wobei die   Führungsstanec zwei Endausschalter trägt,   die mittels eines mit der Svhalldose verbundenen Kontaktarmes den Elektromagnetstromkreis steuern. 



   Die   Vorrichtung gemäss   der Erfindung ist besonders zur Wiedergabe von Reklametexten bzw. zur

 der Zeichnung ist die Erfindung in   Verbindung   mit einem Grammophon veranschaulicht, selbstverständlich kann aber die Tonwiedergabevorrichtung auch durch einen Phonographen gebildet werden. Die Zeichnung zeigt ferner die Tonwiedergabevorrichtung in Verbindung mit einer Projiziereinrichtung. 



   Bei der dargestellten   Ausführungsform   wird der Träger 2 der Grammophonplatte 1 nicht durch ein Uhrwerk, sondern mittels eines Zahn- oder Reibrädergetriebes vom Elektromotor 3 angetrieben, so dass der Plattenträger ununterbiochen gedreht werden kann. Die   Sehalldose   4 ist mit einem Arm 5 verbunden, dessen Hülse 6 entlang einer um den Punkt 7 drehbaren Stange 8 geführt ist. Die Stange 8 besitzt an   il1fe1ll   der Schalldose zuge wandten Teil Übergewicht, so dass die Stange ständig bestrebt ist. in die   dargestellte   Lage zu gelangen, in der die Nadel der   Schalldose mit   der Schallplatte 1 in Berührung steht. Der Ausschlag der Stange 8 wird durch einen Anschlag 9 begrenzt.

   Der an der entgegengesetzten Seite des Drehpunktes 7 liegende Teil der Stange 8 bildet den Anker eines   Elektromagneten M.   Mit dem   Aim 5 sind Anschläge 11, . 3   verbunden, die mit auf der Stange 8 einstellbar angeordneten Endausschaltern zusammenarbeiten. Jeder der Endausschalter besteht aus je einer   Hülse   3, 14, an denen die Kontaktschrauben 15, 16 und die verschwenkbaren Kontaktarme 17, 18 befestigt sind. Die Feder des Kontaktarmes 17 ist bestrebt, letzteren stets geöffnet, d. h. in der dargestellten Lage zu halten, während der   Kon-

 The guide rack carries two limit switches which control the electromagnetic circuit by means of a contact arm connected to the Svhalldose.



   The device according to the invention is particularly suitable for the reproduction of advertising texts or for
 EMI1.3
 the drawing illustrates the invention in connection with a gramophone, but of course the sound reproduction device can also be formed by a phonograph. The drawing also shows the sound reproduction device in connection with a projection device.



   In the embodiment shown, the carrier 2 of the gramophone record 1 is not driven by a clockwork, but by means of a toothed or friction wheel drive from the electric motor 3, so that the record carrier can be rotated continuously. The Sehalldose 4 is connected to an arm 5, the sleeve 6 of which is guided along a rod 8 which can be rotated about the point 7. The rod 8 is overweight on the part facing the sound box, so that the rod constantly strives. to get into the position shown, in which the needle of the sound box is in contact with the record 1. The deflection of the rod 8 is limited by a stop 9.

   The part of the rod 8 lying on the opposite side of the pivot point 7 forms the armature of an electromagnet M. With the aim 5 are stops 11,. 3 connected, which cooperate with limit switches arranged adjustable on the rod 8. Each of the limit switches consists of a sleeve 3, 14, to which the contact screws 15, 16 and the pivotable contact arms 17, 18 are attached. The spring of the contact arm 17 strives to keep the latter always open, d. H. to hold in the position shown, during the con-

 has reached, the stop 11 of the arm 5 of the sound box 4 closes the contact 15, 17, whereby the following stomy ice is closed.
