たことを特徴とするダビングテープレコーダー。 A tape comprising a first motor that drives the tape in a playback tape deck and a second motor that drives the tape in a recording tape deck, and configured to dub a tape playback signal from the playback tape deck onto the tape in the recording tape deck. The recorder detects a non-signal portion of the tape playback signal from the playback tape deck and outputs a pulse width t 1 during an automatic song selection operation, and outputs a pulse width t 2 [where t 2 >t 1 ] during a dubbing operation. A dubbing tape recorder comprising a no-signal detection circuit and a control circuit for stopping the rotation of the first motor for a time t 2 by outputting a pulse width t 2 from the no-signal detection circuit during a dubbing operation.
