    摘要: This invention relates to a record player used for a disc jockey (DJ), and more particularly to a record player suitable for a so-called scratch performance operation by which a phonograph record is directly rotated in forward and reverse direction to output new artificial sound by fingering of an operator which is a kind of DJ performance pattern.
    In order to suppress the needle skip caused when forwardly/inversely rotating the phonograph record by the finger operation, the positional relationship between the record groove on the turntable and the supporting point P of the arm shaft is defined so as to suppress inward and outward component forces applied to the needlepoint of the cartridge as possible. Therefore, three points, i.e., a start point R and an end point S of the record groove on a straight line B extending from the rotating shaft core C of the turntable in a radial pattern and a rotation center of a tone arm, namely, the supporting point P may form an isosceles triangle with the point P as an apex in a most preferable mode.

    摘要: Bei einem Abtastsystem für eine Platte (1) mit einer Rille, z. B. einer PCM-Tonplatte mit Druckabtastung, ist derAbtaster (13) am Ende eines federnden Tragarmes (6) befestigt, der bei der Abtastung radial zur Platte (1) geführt wird. Gemäß der Erfindung ist an dem Tragarm (6) ein zweiter Tragarm (11) gelenkig gelagert. Am ersten Tragarm (6) befindet sich ein reiner Führungskörper (8) und am zweiten Tragarm (11) der eigentliche Abtaster (13). Dadurch wird die Signalabtastung bei Ungenauigkeiten in dem Aufzeichnungsträger (1) wie z.B. Höhen- und Seitenschlägen verbessert.
