PURPOSE:To display the character information while reproducing the music, by driving a magnetic tape of the other side in the interfered state when a magnetic tape of one side is reproduced. CONSTITUTION:Both an AND gate 37 and an OR gate 38 deliver the outputs just by turning on a reproducing switch 28 when a driver 27 is started while the operation of a driver 15 is stopped. Thus a control switch 28 is turned on via the gate 38, and the driver 27 is actuated. In case both reproducing switches 16 and 28 are turned on, the switch 29 is turned on by a music interval detector 31 and with the output of a flip-flop 35 as long as no music is produced from a sound generator 14. However, the flip-flop 35 is reset with the output given from a clause detector 36 to turn off the switch 29 if the characters are displayed by an amount equivalent to a recording unit. |
