Abstract

PURPOSE: To electrically perform the up and down of a tone arm with an operation switch with a simple construction by providing the lift controlling cam for the tone arm to a control cam which performs controlling of lead-in and return of the tone arm.
CONSTITUTION: A control cam 29 is mounted to a sleeve 17 which is vertically movable together with the revolving shaft 6 of a tone arm 5 and the tone arm 5 is led in by the forward running driving of a motor 8. When the record play is finished, the motor 8 is run backward by a position detector, by which the control cam 29 is rotated backward to make return control of the tone arm 5. A cam 38 for arm lifter is provided to the control cam 29 to move the arm downward by lowering the lifter 12 when the arm is at the lead-in and move the arm upward at the time of return control. Further, when the down switch provided to the panel is turned ON, the motor 8 runs forward to move the arm 5 downward and when the up switch is turned ON, the motor 8 runs backward to move the arm 5 upward.
