Abstract
PURPOSE: To eliminate the need for height adjustment of a lifter at the height adjustment of a tone arm by providing an elevation-control cam of arm lifter to a control cam which controls the arm installed to a member moving vertically integrally with the rotating shaft of the tone arm.
CONSTITUTION: The horizontal rotating shaft 6 of a tone arm 5 is inserted rotatably in a sleeve 17 and the sleeve 17 is moved vertically with respect to a bearing block 7 to adjust its height and is then fixed by a screw 20. A control cam 29 is rotatably mounted to the sleeve 17 to perform the lead-in and return control of the arm 5 through forward and backward running of a motor 8. The lifter shaft 60 of the lifter 12 of the arm 5 is provided vertically movably to a bearing 63 and its bottom face is energized and pressure-contacted by a spring 62 to the arm lifter control cam 38 provided on the control cam 29. The arm 5 is then moved up or down in correspondence to the lead-in and return control of the arm 5 by the revolution of the cam 29.
