Intermusic detector of tape recorders, or the like

Abstract

Abstract PURPOSE: To enable the music desired to be listened to be listord early when the place where the music desired to be listened has been recorded is unknown by reproducing only the head portions of plural musics and letting the tape run at a high speed for other portions. CONSTITUTION: When a head 2 detects the head of a music, an output is obtained from a rectifier circuit 4. Then a switch circuit 5 actuates and at the same time a transistor 8 goes ON to invert the output of a flip-flop 9 a transistor 10 goes OFF, causing a capacitor 12 to begin to be charged. Until a fixed charging voltage is reached, the tape is fed at a reproduction speed and the reproduction signal, i.e., music, may be listened to through an AF amplifier 20 and a speaker 21. When the listener identifies which music only from the leading end portion of the music and leaves that state intact, the voltage of the capacitor 12 immediately reaches a fixed value and the tape runs at a high speed and therefore the recorded portion desired to be listened is known early. If manual switches 18, 19 are turned OFF at the portion of the music desired to be listened, a motor 6 causes the tape to run at the reproduction speed COPYRIGHT: (C)1979,JPO&Japio
