Abstract

PURPOSE: To perform down motion rapidly by increasing the rotating speed of an arm driving motor within the lead-in section and rotate the control cam at a high speed at the time of performing down operation by setting the tone arm in an arbitrary position on a record manually.
CONSTITUTION: When a tone arm 5 is set in an arbitrary position of a record disc R manually from an arm rest 13 and a down switch is turned ON, an arm driving motor 8 runs forward to rotate a control cam 29. At the same time, a cam 38 for arm lifter turns to lower the lifter shaft 60 of an arm lifter 12, thus automatically moving the arm 5 down onto the record disc R. At this automatic down operation, the rotating speed of the arm driving motor 8 is increased within the lead-in section to rotate the control cam 29 at a speed higher than normal within the lead-in section, whereby the auto-down operation is rapidly accomplished.
