Abstract

PURPOSE: To prevent a tone arm from descending when operator's hands are separated from an operation finger-screw on the way of operation, by providing a control means which performes the descend operation of the tone arm after confiming a set position.
CONSTITUTION: When operator's hands are separated from finger-screw 14 before the output of error detection circuit DET, which detects a coincidence signal generated when tone arm 1 comes to a desired set pssition, namely, a zero volt signal, is generated, the second gate circuit G2 is not established, and a FF circuit is not reset, and tone arm 1 does not descend. therefore, the stylus tip of the tone arm can be caused to descend to an objective position on the record disc surely by touching finger-screw 14 with hands again when the output of error detection circuit DET is generated, that is, tone arm 1 is stopped or waiting the tone arm stop while touching the finger-screw with hands.
