Abstract

PURPOSE: To detect the area between musics without receiving any effect of the disturbed light during the reproduction of record music, by producing the inter- music signal when the output of a pickup is kept under a prescribed level for a prescribed time.
CONSTITUTION: First a pickup 1 of a record player begins to trace the groove between the pieces of record music, and thus the output aural signal of the pickup lowers. The prescribed frequency band of the aural signal is amplified by an amplifier 2, and a level deciding circuit 3 produces the decision signal when the output signal of the amplifier 2 is under a prescribed level, e.g., the aural signal is substantially at zero level. Then a counter 5 has an overflow to produce the inter-music signal in case the decision signal continues for a prescribed time. While the counter 5 is reset if the decision signal does not continue for a prescribed time.
