Abstract

PURPOSE: To eliminate the useless time and thus secure a quick and smooth performance, by carrying out the instruction of the tone arm, the detection of the record disk size and the detection of rotational frequency of the turntable simultaneously and in parallel.
CONSTITUTION: The control circuit 2 operates with push of the start button on the control board, and both the turntable drive circuit 4 and the tone arm drive circuit are energized. At the same time, the plunger 10 is energized to give an engagement between the motor 9 and the tone arm both of which are then shifted to the outer circumference of the record disk. The size of the disk is detected by the detector 15 at the time point t1, and the detection signal Sa or S4 is delivered to the terminals (a) and (b). When the rotational frequency of the turntable 6 reaches the prescribed level at the time point t2, the output of the AND circuit 13 leads continuously the arm from the circuit 4 via the inverter 14 and with "0". When the deenergization signal S5 is obtained, the plunger 10 is energized to cancel the engagement between the motor 9 and the arm. Then the stylus tip falls onto the record disk.
