Abstract

Abstract PURPOSE: To rotate the turntable at the time when the arm lifter operates when the tone arm is brought to a horizontal and predetermined position. CONSTITUTION: When the man touches the knob 14 of the position setting variable resistor VR 1 of the tone arm 1, the ham component is formed so as to put out as output to the terminal 15. If the knob 14 of the resistor VR 1 is rotated, the elevating arm 1 is rotated horizontally by the operation of the horizontally driving portion 3 and can be stopped at a predetermined position. At this time, separating the hand from the knob 14, the output of the terminal 15 is removed and the arm starts to be lowered by the vertical driving portion 9 and at the same time, the output during reset of FF 1 is added to FF 2 through the differential circuit DE and set. By the output from the terminal 21, the motor is driven and the turn table can be rotated. COPYRIGHT: (C)1980,JPO&Japio
