Date May 3, 1979.An automatic telephone answering device with simultaneous drive for the outgoing message tape (T-1) and the incoming message tape T-2 has a disadvantage in that the calling party's voice cannot be recorded within a section of T-2 (T2-1, T2-3) which is driven simultaneously with the first half (T1-1, T1-3) of T-1. To prevent this disadvantage, T-2 is to be automatically rewound within the wasted section (T2-1 and T2-3). Then, it records the calling party's voice on the section (T3-1 and T3-2). The instant rewinding distance depends on the tape volume on the tape reel but the above rewinding section is not overrun to the previous recording section (T3-1 and T3-2). So, it must have minimum blanks l1, l2, . . . ln.
