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 keep 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 music selection operation, and outputs a pulse width t 2 [where t 2 >t 1 ] during a dubbing operation. A first control circuit includes a no-signal detection circuit, and stops the rotation of the first motor for a time t2 by outputting a pulse width t2 output from the no-signal detection circuit during a dubbing operation; a second control circuit that stops the rotation of the second motor after a certain period of time and restarts the rotation of the second motor when the no-signal detection circuit detects a tape playback signal from a playback tape deck; A dubbing tape recorder featuring
