<p>PURPOSE:To recognize the present state of a tape traveling with an on-off rhythm of a tone by providing a tone generating circuit for audio frequency band and a circuit for controlling the operation of the tone generating circuit in order to notify the state. CONSTITUTION:An output from the tone generating circuit 9 is connected via resistors to the output sides of power amplifiers 1 on right and left, and since the output sides of the power amplifiers 1 are of high impedance when a muting output 8 is outputted, all the tones when outputted from the tone generating circuit 9 at that time flow to a speaker 4 to sound the speaker 4. Then, the operating time and the stopping time of the tone generating circuit 9 are optionally decided in accordance with the transition state from the reproducing state to program a control circuit 5 for issuing various commands in response to receiving a pulse signal of a remote switch 3, so that the tone can be sounded in free rhythm.</p> |
