Abstract

PURPOSE: To ensure a high-accuracy and assured automatic playing by detecting the intervals between the record music twice by the tone arm from the outer circumference of the dik to the center and from the center to another outer circumference and then giving a comparison between the detection value.
CONSTITUTION: Arm driving unit 14 is actuated by the output of FF 13, and at the same time a connection is given to control 1st memory unit 15. Then the output given from inter-music sensor 16 consisting of light emitting element 10 and photo detector 11 is supplied to unit 15. In the same way, the output of FF 13 and sensor 16 are supplied also to 2nd memory unit 17. Unit 15 memorizes the music interval on the record unit tone arm 5 passes the center of the record; while unit 17 memorizes the music interval from the center of the record to the final retaining position. And these detection value are supplied to comparator 20. As a result, a high-accuracy and assured automatic playing can be secured.
