PURPOSE:To make the spot erasion in fine units possible, by making the rotation speed of a capstant and the running speed of a tape low to perform the spot erasion. CONSTITUTION:An erasing signal generating circuit 8 turns on a connection switch 10 controlled by an erasing control signal from an editing control device 9 and is operated to generate an erasing signal 8a, which rises with a prescribed time constant, when a positive DC voltage from a power supply terinal +B is supplied. This erasing signal 8a is supplied to an erasing head 5 to execute the erasing operaton. A reproduced sound signal from a reproducing head 6 is supplied to a speaker 13 through a series circuit consisting of an amplifying circuit 11 and a muting circuit 12 for reverse of the spot erasion controlled by a control signal from the editing control device 9. |
