Abstract

PURPOSE: To perform brake control accurately irrespective of the height adjustment of a tone arm by mounting a control cam which controls the tone arm and a brake lever which is controlled by this lever to a sleeve which moves vertically together with the rotating shaft of the tone arm.
CONSTITUTION: The horizontal rotating shaft 6 of a control arm 5 is mounted turnably within a sleeve 17 and the sleeve 17 is made vertically movable with respect to a bearing block 7 and is fixed to a required height by an adjust screw 20. A control cam 29 is rotatably inserted into the sleeve 17 to make lead-in and return control of the tone arm through forward and backward running of the motor 8. When the lead-in and return operation of the tone arm are made, a brake lever 110 is actuated by the cam provided to the lower side of the control cam 29 to let the shoe 115 thereof make pressure contact to the brake drum 92 secured to the rotating shaft 6 of the tone arm, thereby causing brake to act.
