Abstract

PURPOSE: To prevent permanent deformation by avoiding to give unnecessary stress on the elastic member of the arm, and to make easy for the cleaning of the reproducing needle by brushing, through the provision of the arm lifter electromagnetically controlling the reproducing needle arm for the lifting up and down control.
CONSTITUTION: At the end of playing, the reproducing needle 9 is in codntact with the brush 12 supported on the chassis on its way to the pause position to clean up attached dust. The microswitch 32 is present at the moving path of the carriage stand 6, and the reproducing needle 9 is lifted woen with the power application of the electromagnetic coil 26 through the detection of the reproducing needle 9 approaching the brush 12. When the carriage 3 is stopped at the pause position, the power of the electromagnet 26 is interrupted, the permanent magnet 33 lifts down the reproducing needle 9 to the reproducing position to keep elastic support member 22 not being exerted from permanent deformation.
