Abstract
PURPOSE: To let a tone arm move down automatically through one operation by prohibiting the forward movement of a lead-in driving member and allowing only the down driving member to move forward through the actuation of a electromagnet when the tone arm is set manually on a record disc and a down switch is pushed.
CONSTITUTION: When a down switch is turned ON after manual leading-in of a tone arm, a motor runs to rotate forward a control cam 29 for tone arm drive controlling. At the same time, an electromagnet 122 is energized, and as the electromagnet 122 attracts a stopper plate 119, the plate 119 turns from the position of a dot-dash-line to the position of a solid line against a tension spring 121 about a fulcrum shaft 120. As a resutl, the pin 69 of a lead-in lever 30 having turned together with the cam 29 contacts and stops the lead-in lever 30 in that position. At this time, a limiter 70 for lead-in disengages from the cam for limiter. Hence, the auto lead-in operation of the arm by the lead-in lever 30 is automatically set and the need for prior resetting is eliminated.
