Abstract

The invention relates to a system for automatically controlling record players. On the circumference of the disc label of a record there is printed opto-electronic information, which contains record-specific data in the form of a bar code. The bar code is evaluated with the aid of an optical reader.

Description

System zur automatischen Steuerung eines PlattenspielersSystem for the automatic control of a turntable

Die Erfindung bezieht sich auf ein System zur automatischen Steuerung eines Plattenspielers, wie es im Oberbegriff des Patentanspruchs 1 wiedergegeben ist.The invention relates to an automatic control system a turntable as reproduced in the preamble of claim 1 is.

Es ist bekannt, daß der Durchmesser einer Schallplatte die Lage der Einlaufrille und zum überwiegenden Teil auch die Umdrehungsgeschwindigkeit festlegt. Weiterhin ist bekannt, daß nach Erreichen der Auslaufrille der Plattenspieler abgeschaltet wird. Es ist aus der Funkschau 1976, Heft 9, Seite 338 (72) auch bekannt, Kennrillen einer Schallplatte automatisch zu erkennen und daraus die Lage und Anzahl der Musiktitel zu verarbeiten, so daß eine vorprogrammierte Auswahl von Musiktiteln abrufbar ist. Bei der Art der auto-.matischen Erkennung von Kennrillen einer Schallplatte ist jedoch ein spezielles Tonabnehmersystem notwendig. Weitere Steuerungsmöglichkeiten eines Schallplattenspielers sind bei den bekannten Lösungen nicht vorhanden.It is known that the diameter of a record depends on the location of the Infeed groove and for the most part also the speed of rotation. It is also known that the turntable is switched off after the outlet groove has been reached will. It is also known from Funkschau 1976, issue 9, page 338 (72), identification grooves to automatically recognize a record and from this the position and number of music tracks to process, so that a preprogrammed selection of music titles can be called up. The type of auto-.matic recognition of identification grooves on a record is however, a special pickup system is necessary. Further control options a record player are not available in the known solutions.

Aufgabe der Erfindung ist es, ein einfaches System zur automatischen Steuerung eines Schallplattenspielers zu finden.The object of the invention is to provide a simple system for automatic Find control of a turntable.

Diese Aufgabe wird durch die im Anspruch 1 beschriebene Erfindung gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.This object is achieved by the invention described in claim 1 solved. Advantageous further developments of the invention are described in the subclaims.

Nlit Hilfe der Erfindung ist die automatische Steuerung verschiedener Plattenspielerfunktionen möglich. Die Information für die verschiedenen Steuerfunktionen ist als opto-elektronisch lesbare Information auf dem Plattenetikett im inneren Drittel einer Schallplatte aufgedruckt.With the aid of the invention, the automatic control is various Record player functions possible. The information for the various control functions is inside as opto-electronically readable information on the plate label Third of a record printed on it.

Die opto-elektronisch lesbare Information kann aus Daten bestehen, die z.B. die Umdrehungsgeschwindigkeit, Kompanderfunktion, Position der einzelnen Stücke usw. enthalten. Durch die festgelegte Umdrehungsgeschwindigkeit ist eine konstante Auslesegeschwindigkeit vorhanden. Weiter wird die gesamte opto-elektronisch lesbare Information bei jeder Umdrehung einmal gelesen. Deshalb kann auf eine Zwischenspeicherung der Daten oder eines Teils der Daten verzichtet werden. Ist keine opto-elektronisch lesbare Information vorhanden oder ist diese beschädigt, so wird auf normale Bedienungsfunktion zurückgeschaltet.The opto-electronically readable information can consist of data, e.g. the speed of rotation, compander function, position of the individual Pieces etc included. The specified rotational speed is a constant readout speed available. Next, the whole is opto-electronic Readable information read once with each revolution. Therefore, caching can be used the data or part of the data are waived. Is not opto-electronic Legible information is available or if this is damaged, normal operating functions are activated switched back.

Die opto-elektronisch lesbare Information kann vorteilhaft in Form eines sogenannten Strich-Codes aufgebracht werden.The opto-electronically readable information can advantageously be in the form a so-called bar code can be applied.

Dieser Strich-Code ist so aufgebaut, wie es in "Elektor", Heft 6/81, Seiten 36 bis 39 beschrieben ist. Diese Codierungsart findet weite Verbreitung zur Warenkennzeichnung usw.. Deshalb sind Lesevorrichtungen und Auswerteelektronik günstig verfügbar.This bar code is structured as it is in "Elektor", issue 6/81, Pages 36 to 39 is described. This type of coding is widely used Labeling of goods etc. Therefore reading devices and evaluation electronics are cheap available.

Bin Ausführungsbeispiel der Erfindung wird anhand der Zeichnung erläutert. Darin zeigen: Fig. 1 ein Plattenetikett Fig. 2 einen Plattenspieler mit optischen Leser.An exemplary embodiment of the invention is explained with reference to the drawing. 1 shows a disk label; FIG. 2 shows a disk player with optical Reader.

Fig. 1 zeigt eine Schallplatte 1 mit einem Plattenetikett 2 und einem Zentrierloch 4. Am äußeren Rand des Plattenetiketts 2 ist eine opto-elektronisch lesbare Information 3 in Form eines Strich-Codes aufgebracht. Bei einem Durchmesser des Plattenetiketts 2 von ca. 10 cm ergibt sich eine mittlere Länge der opto-elektronisch lesbaren Information 3 von ca. 30 cm. Mit dieser Länge lassen sich selbst bei geringer Genauigkeit des Druckverfahrens und bei Verwendung einfacher und kostengünstiger optischer Lesesysteine wenigstens 200 Bit Information auf den Umfang aufdrucken.Fig. 1 shows a record 1 with a record label 2 and a Centering hole 4. On the outer edge of the plate label 2 is an opto-electronic legible information 3 applied in the form of a bar code. at a diameter of the plate label 2 of approx. 10 cm results in an average Length of the opto-electronically readable information 3 of approx. 30 cm. With this length can be used even with poor printing process accuracy and usage simple and inexpensive optical reading system with at least 200 bits of information print on the circumference.

Selbst bei Verwendung einer hohen Code-Redundanz zur Datensicherung reichen diese 200 Bit aus, um z.B. Umdrehungszahl, Kompanderfunktion und 10 Positionen auf dem nutzbaren Teil des Plattenradius anzugeben. Bei 10 Positionen kann dann jede einzelne Position auf ca. 0,1 mm festgelegt werden.Even when using a high level of code redundancy for data backup these 200 bits are sufficient to e.g. number of revolutions, compander function and 10 positions on the usable part of the plate radius. With 10 positions then each individual position can be set to approx. 0.1 mm.

Fig. 2 zeigt einen Plattenspieler mit einem optischen Leser 6 und einer Abdeckhaube 5. Bei geschlossener Abdeckhaube 5 ist der optische Leser 6 so angeordnet, daß er die auf dem Plattenetikett 2 aufgedruckte opto-elektronisch lesbare Information 3 auswerten kann.Fig. 2 shows a record player with an optical reader 6 and a cover 5. When the cover 5 is closed, the optical reader 6 is like this arranged that he the printed on the plate label 2 opto-electronically readable Information 3 can evaluate.
