Abstract

PURPOSE:To reset the object being controlled rapidly when it moved further from the specified position by controlling a driving means based on the DA conversion output of a counter for moving position detecting pulses. CONSTITUTION:When the player is stopped, a counter 34 which is started by the stop instruction signal when a tone arm 1 being the object being controlled passes by the specified stop position owing to inertia begins to count the pulse signals P from a detecting circuit 32, but the arm 1 turns in the arrow a direction and therefore the counter counts up based on the discrimination signal S of high level indicating the turning in the a direction. This output is made to an analog voltage E in a D/A converter 35 and is then applied to a horizontal control circuit 36, causing such a voltage which turns the arm 1 in the arrow b direction to be applied to a coil 10. Next, when the arm 1 turns in the b direction, the counter 34, is counted down from the count value by the discrimination signal of a low level, causing such a voltage which turns the arm 1 in the a direction to be applied to the coil 10. This is repeated to let the arm 1 stop rapidly in the specified position.
