PROBLEM TO BE SOLVED: To provide a turn detection device capable of easily controlling audio data of different electronic equipment by an analog record with audio data recorded. SOLUTION: When a supporting member 10a is turned, a slippage prevention member 9d is brought into close contact with a thick part 4a of the analog record 4, and friction force between the slippage prevention member 9d and the analog record 4 makes a rotator 9a rotatable with respect to the analog record 4. When a performer scratches the analog record 4 while playing the analog record 4, the rotator 9a rotates centering on a shaft 9e in accordance with the rotation of the analog record 4. A rotary encoder 9b detects a rotation speed and a rotating direction of the rotator 9a and outputs a pulse signal, Audio data of a data reproducing device 3 are subjected to scratch control on the basis of the pulse signal.
