PURPOSE:To achieve economical and easy handling, by recording the response message and the business information on one magnetic tape and releasing the recording mode if the additional time for the time elapsed for recording exceeds a prescribed valve. CONSTITUTION:When the business recording is started, a timer circuit 62 detects the elapsed time, and after passed 30sec, an instruction is given from a timer set circuit 60 to a CPU to make the release of recording. When the business recording is finished within 30sec, the recording is released and the elapsed time detected with the timer 62 is added to an addition circuit 63. The total time of the recording time stored in a timer memory 64 up to preceding time and a given value 600sec set in a timer set circuit 61 are compared at a comparison circuit 65 every time at the end of the business recording, and if they are in agreement, or close to each other, the automatic answering recording mode can be released. Thus, a tape drive system can be provided only one for one set and the users can prepare for only one tape. |
