PURPOSE:To execute synchronized sound recording, by providing a detecting means for detecting that a tone arm is in other position than an arm rest, a signal generating means for making the tone arm queue down or queue up, and an output terminal of a pause signal. CONSTITUTION:When a tape recorder is set to a sound recording pause state and a start button of a record player is pushed, a tone arm rises from an arm rest and A pulse a is generated from a signal generating means 2, but since an output of a detecting means 1 is ''L'', no pause signal is generated. Thereafter, when the tone arm turns and reaches the edge of a record, the output signal of the detecting means 1 becomes ''H'', and when it further turns and queue-down is executed, a pulse B is generated and a pause signal from an AND circuit 3 is impressed to a pausing circuit 4, therefore, a pause of the tape recorder is released, and a melody of the record player is sound-recorded. When it reaches the end part of a prescribed melody, the tone arm is brought to queue-up, a pulse C is generated, and the tape recorder becomes a sound recording pause state again. In this way, synchronized sound recording can be executed without causing a malfunction. |
