ド演奏終了検出装置。An optical detector that performs ° detection by turning on and off depending on the formation/non-formation of an optical path, and a plurality of predetermined position ranges that are linked to the tracing operation of a pickup and correspond at least to the play end positions of records of various diameters. An operating body that operates the optical detector and receives the on/off output of the optical detector compares the time from the start of operation of the detector to the end of operation with a set time to determine the end of record playing. A record performance end detection device comprising: a time verification circuit.
