Description

hineingreift, an der der Löschkopf eines konventio- 45 schwenkbaren Umlenkbolzen 10 trägt. Über die Achseengages, on which the extinguishing head carries a conventional 45 pivotable deflection bolt 10. About the axis

nellen Kassettentonbandgerätes angeordnet ist.nellen cassette tape recorder is arranged.

Die Erfindung betrifft ein Tonbandgerät für Lehrzwecke, bei dem eine Umlenkvorrichtung zur Bildung einer Bandschleife vorgesehen ist und bei dem eine aufgezeichnete Lehrerspur wiedergegeben und eine der Lehrerspur nachgesprochene Schülerspur aufgezeichnet wird und im Anschluß daran beide Spuren wiedergegeben werden.The invention relates to a tape recorder for teaching purposes, in which a deflection device for formation a tape loop is provided and in which a recorded teacher track is played and one of the Teacher track after-spoken student track is recorded and then both tracks be reproduced.

Bekannte Geräte dieser Art sind bisher als Tonbandgeräte normaler Bauart, d. h. mit zwei getrennten Wickelspulen ausgebildet. So ist in der US-PS 34 23 850 ein Tonbandgerät für Lehrzwecke beschrieben, bei dem zwei getrennte Wickelspuren verwendet werden. Aus dieser Druckschrift ist es bekannt, eine Bandschleife herzustellen, indem eine Rolle, die auf einer Schiene verschiebbar angeordnet ist, auf dieser Schiene senkrecht zur Bandlaufrichtung in das Innere des Tonbandgerätes verschoben wird und dabei das Tonband mitnimmt.Known devices of this type are so far as tape recorders of normal design, d. H. with two separate Winding bobbins formed. Thus, in US-PS 34 23 850 a tape recorder for teaching purposes is described in which two separate winding tracks can be used. From this publication it is known a belt loop manufacture by a roller, which is arranged displaceably on a rail, on this rail is moved perpendicular to the direction of travel of the tape into the interior of the tape recorder and thereby the Takes away tape.

Bei Lehrveranstaltungen, z. B. beim programmierten 11 des Umlenkbolzens 10 ist eine Feder 12 geschoben, die einerseits am Träger 9 und andererseits an einer Abbiegung 13 befestigt ist. Die Abbiegung 13 läuft beim Verschieben des Trägers 9 in einer Führungsrille 14 im Grundkörper 1. Die Führungsrille 14 erweitert sich an der Sperrplatte 4 zu einer trapezförmigen öffnung 15. Am oberen Ende des Trägers 9 ist eine Verzahnung 16 vorgesehen, die dazu dient, den Träger 9 an einem Band 17, das über zwei Rollen 18 auf den Flanschen 2 geführt ist, zu befestigen und zu verstellen.For courses, e.g. B. with the programmed 11 of the deflection bolt 10, a spring 12 is pushed, which is attached on the one hand to the carrier 9 and on the other hand to a bend 13. The turn 13 runs at Moving the carrier 9 in a guide groove 14 in the base body 1. The guide groove 14 widens the locking plate 4 to a trapezoidal opening 15. At the upper end of the carrier 9 there is a toothing 16 provided, which serves to attach the carrier 9 to a belt 17 which is guided over two rollers 18 on the flanges 2 is to be attached and adjusted.

Wird nun der Träger 9 bis zum vorderen Flansch 2 bewegt, so läuft die Abbiegung 13 auf die Führungskante 5 auf und wird durch sie um 90° gedreht. Dadurch wird auch der Umlenkbolzen 10 so weit herumgeschwenkt, daß er unter einem Tonband 19 hindurch in eine Kassette 20 geschoben werden kann. Ist dies erfolgt und rastet man die Sperrplatte 4 aus, wodurch die Feder 12 die Abbiegung 13 wieder in ihre alte senkrechte Lage zurückdrückt, dann faßt der Umlenkbolzen 10 hinter das Tonband 19. Bewegt man den Träger 9 jetzi auf den Flansch 2 am anderen Ende des Grundkörpers 1 zu, so zieht der Umlenkbolzen 10 eine Tonbandschleife aus der Kassette 20.If the carrier 9 is now moved as far as the front flange 2, the bend 13 runs onto the leading edge 5 and is rotated by 90 ° by it. As a result, the deflection bolt 10 is also pivoted around so far that that it can be pushed into a cassette 20 under a tape 19. Is this takes place and the locking plate 4 is disengaged, whereby the spring 12 returns the bend 13 to its old one vertical position pushes back, then grabs the deflection pin 10 behind the tape 19. If you move the Carrier 9 now on the flange 2 at the other end of the When the base body 1 closes, the deflection bolt 10 pulls a tape loop out of the cassette 20.

Claims

Patent claims:

t. Tape recorder for teaching purposes, in which a deflection device for forming a tape loop is provided and in which a recorded teacher track is reproduced and one of the rspur re-spoken student track is recorded and then both tracks are reproduced, characterized in that for the formation of loops when operating with cassettes in front of an opening in one of the narrow sides of the A cassette (20) which can be displaced on a guide essentially perpendicular to this narrow side Deflection bolt (10) is arranged, which can be inserted into the cassette (20), always during insertion assumes a position parallel to the direction of travel of the tape and in the end position in a position to the direction of travel of the tape vertical position is pivotable and can be locked in this position during pulling out.

2. Tape recorder according to claim 1, characterized in that the deflection bolt (10) as front bend of an axis (11) mounted in a carrier (9) is formed that the carrier (9) is displaceable on the guide rail (3), and that the rear end of the axis (11) is opposite is bent to the deflection pin (10) and is supported by a spring (12) on the carrier (9) is held in a vertical position that in the way of this lower bend (13) a locking plate (4) is, which is provided with a correspondingly shaped leading edge (5), which when Pushing the deflection bolt (10) into the cassette (20) turns the bend (13) to the side, and that the locking plate (4) against the pressure of a tension spring (6) out of the way of the bend (13) can be swiveled out.

3. Tape recorder according to claim 1 or 2, characterized in that the guide with the required associated tape heads on the cassette tape recorder, in exchange for conventional equipment with a sound and erase head, can be attached.

4. Tape recorder according to claim 3, characterized in that the deflection bolt (10) on the Place under the tape (19) in the cassette (20) Lessons, you go to it instead of tape recorders normal design so-called tape cassette devices to be used, as these include. are easier to use. With these devices, the tape is no longer freely accessible, but runs in all operating modes inside a cassette. A sound head is inserted into the cassette for recording and playback.

The invention was based on the object of the above-mentioned mode of operation also with tape cassettes to enable.

The solution to the problem is characterized according to the invention in that for the loop formation when operating with cassettes in front of an opening in one of the narrow sides of the cassette on a guide is arranged essentially perpendicular to this narrow side displaceable deflection bolt, which is in the Cassette is insertable, always assumes a position parallel to the tape running direction during insertion and in the End position can be pivoted into a position perpendicular to the direction of travel of the tape and in this position during the Pulling out is lockable.

This solution has the advantage that every common form of cash register can be used without additional changes can be.
