<p>PURPOSE:To select a piece of music which recorded on an opposite surface by inverting a tape travelling direction, continuing to feed quickly and detecting a designated piece of music based upon coincidence of an inter-music signal calculated value with a value corresponding to the designated piece of music. CONSTITUTION:When the number of music in accordance with designated music is designated to an adder subtracter circuit 13 by a music designating means 14 and a music selecting command is impressed to a music selecting action part 33, a quick-feeding command is issued to an FF switch 20, etc., a head 1 is contacted with a tape, an inter-music signal is counted at the circuit 13 and the circuit 13 outputs H as far as a calculated value is not coincident with the set number of music. When a tape terminator detecting circuit 17 detects a tape terminator during retrieving a tape A surface, a one-shot multi 32 is triggered, a transistor 30 becomes on and an FF action of the switch 20 stops and a solenoid 6 is excited through an AND gate 18 and switches 26 and 27 are changed over. Thus, a tape travelling direction is inverted and the music recorded on a tape B surface is selected by an inter-music signal from the tape which is quickly fed continuously.</p> |
