Abstract

PURPOSE: To enable lead-in with the minimum distance even if the arm is at any position, by shifting the pickup through the provision of the arm position detector and the record disc diameter designation unit.
CONSTITUTION: When the pickup arm is positioned between the introduction points of record diameters 25 and 17cm and the arm is returned to the introduction groove of the record diameter 25cm, the designation button 18 is again operated. In this case, the content of the arm position detection signal D inputted to the input terminals A1WA3 of the comparator 15 is "110", and the content of the record diameter designation signal R inputted to the input terminals B1WB3 is "001". Accordingly, the relation of largeness of the signal D<R is judged from the comparator 15, the control signal of feed right is outputted to shift right the arm. Further, when the arm reaches the position of introducing groove of record diameter 25cm, the comparator 15 judges the state of signal D=R, the stop control signal is outputted to lead in the pickup arm in minimum distance.
