Abstract

PURPOSE: To know a music number in a short time by detecting a non-signal part and calculating its position when a music tape is running at a high speed, and then by displaying the music number by previously comparing the position of the part to that expressed in probability distribution by the mean value of music length and dispersion.
CONSTITUTION: The probability distribution of the position of an inter-music non- signal part obtained with the mean value and dispersion of the music length of a music tape is stored in address table 7. A signal reproduced by reproducing head 2 when the tape is running is amplified by amplifier 3 and the non-signal part is detected inter-music non-signal-part detecting circuit 4. Reel rotational-period detecting circuit 5, on the other hand, detects the rotational periods of reels and arithmetic circuit 6 calculates the position of the tape. The obtained position is compared with the contents of address table 7 stored with tape positions corresponding to music numbers and music-number determining circuit 8 determines the music number, which is displayed on display unit 9. The music number can therefore be known in a short time.
