<p>PURPOSE:To simplify operation, to reduce memory capacity and to reduce cost by setting the start or end position of music by detecting an unrecorded part according to mode. CONSTITUTION:To listen to music from its beginning at a desired position of the music, memory write switch 10 is closed to write the value of counter 6 in memory 9 and while repear mode switch 13 is set to mode A, the repeat indication switch is closed to start repeat operation. At the 1st unrecorded part of the music, the detection signal of unrecorded-part deciding circuit 3 is output to one-side terminals of AND circuits 15a and 15cd and since switch 13 is set to mode A, a signal of ''1'' is sent to the other-side terminal. As a result, OR circuit 16a outputs reproduction mode signal 17, so that the music can be listened to from its beginning. At a desired halfway position, the value of counter 6 agress with the stored value of memory 9 and comparator 11 inputs indentity signal 12 to one-side terminals of AND circuits 15b and 15d; and circuit 15b, therefore, inputs the ''1'' signal to OR circuit 16b, which outputs the rewind signal.</p> |
