Claims (1)
路を設けることにより、 再生信号をモニタしながら録音済テープの消去部分の開
始点が近づくのを認知した時点で前記モータ制御回路に
より速度を低下させ、 該開始点を認知した時点で消去ヘッドに制御電流を流す
ためのテープ消去用のスイッチをオンさせ、消去部分の
終了点までオン状態を維持し、該終了点を認知した時点
で、該オン状態を解除するようにしたことを特徴とする
録音済テープの一部消去装置。[Scope of Claim for Utility Model Registration] By providing a motor control circuit that can vary the speed of the capstan motor, the above-mentioned system can be activated when the reproduction signal is monitored and it is recognized that the start point of the erased portion of the recorded tape is approaching. The speed is reduced by the motor control circuit, and when the starting point is recognized, the tape erasing switch for supplying a control current to the erasing head is turned on, and the on state is maintained until the end point of the erasing section, and the tape erasing switch is turned on until the end point of the erasing section is reached. A device for partially erasing a recorded tape, characterized in that the on-state is canceled when the on-state is recognized.
