ABSTRACT:
A control device having a reciprocable drive element connected to a record command disc, a pick-up arm set down position selection member, and a guide element pivotally connected to the drive element for engaging a coupling element on a pick-up arm base to guide the pick-up arm pivoting toward the turntable. The guide element is pivotable with respect to the drive element between two stable positions. In the first stable position during forward movement of the drive element, the guide element passes an abutment on the pick-up arm base, and is then pivoted to the second stable position. During a turn movement of the drive element, the guide element first pivots the pick-up arm into abutment with a set-down position selection surface, and the guide element then pivots out of engagement with the abutment. Upon completion of the drive element return movement, the guide element is pivoted into the first stable position.
