DESCRIPTION:
BRIEF SUMMARY
FIELD OF ART
This invention pertains to the tape driving system and the device which are used in the automatic telephone answerer, and which minimize a wasted section of the incoming message tape which is unavoidable in the prior arts of the automatic telephone answerer, wherein it drives both the out-going message tape and the incoming message tape simultaneously upon receipt of a telephone call, and makes the incoming message tape the recording mode upon finishing of the first half of the out-going message tape and resets the device in the stand-by mode upon finishing of the latter half of the out-going message tape and this invention belongs to Main Classification HO4M 1/64 of IPC.
BACKGROUND ART
In the prior art of the automatic telephone answerer, to which the invention is directed, there have been two kinds of the tape. One is the out-going message tape (hereinafter called "T-1") and another is the incoming message tape (hereinafter called "T-2"). The above two tapes are driven sequentially or simultaneously and performs the operations of sending an announcement and of taking messages. For instance, in the Japanese Pat. No. 424,747 (Application Ser. No. 36-8531), T-1 is driven at first upon receipt of a telephone call, and then T-2 is driven after T-1 stops. In the simple model of the automatic telephone answerer, for instance, the Japanese Pat. No. 491,669 (Application Ser. No. 39-7915), T-1 and T-2 are driven simultaneously upon receipt of a telephone call and the operation time of T-2 is controlled by one cycle of T-1. In the latter patent, the out-going message is pre-recorded on the first half of T-1, for instance, for 20 seconds, and a beep-tone is generated by the conventional method. Then, it can take the incoming message on T-2. However, during the above 20 seconds, T-1 and T-2 are driven simultaneously. So, there should be a 20-second blank between the previous message and the next message every time the user plays back the T-2, but the above blank of tape is regarded as an unavoidable waste in the said driving system. Among many automatic telephone answerers, there is one kind of the device as the Japanese Pat. No. 532,850 (Application Ser. No. 42-79425), which records not only the incoming message but also the out-going message on T-2 in every operation. The above tape driving system is called "simultaneous driving method" in the United States of America. For instance, the automatic telephone answerer with the trade name "Tele-Tender" on the United States market adopts the above method, but in ordinary cases, it is intricate and troublesome for general users to hear the out-going message every time before listening to every incoming message which has been recorded on T-2. It can be understood that the above 20 seconds is anyway a waste of time for users, but the above disadvantage has been regarded as an inevitable demerit in these prior arts.
DISCLOSURE OF THIS INVENTION
This invention is to enable the automatic telephone answerer, which drives both the out-going message tape (hereinafter called "T-1") and the incoming message tape (hereinafter called "T-2") simultaneously upon receipt of a telephone call and controls the driving time of T-2 by one cycle of T-1, to automatically fast rewind T-2 alone within the length of the wasted section of T-2 which has been driven simultaneously with the first half of T-1 (hereinafter called "wasted section") immediately after the out-going message is finished and the beep-tone is generated, and then to record the incoming message at the ordinary tape driving speed.
For rewinding the above wasted section of T-2, this invention is to enable the control means to prevent erasing of the previously-recorded message caused by over-driving, irrespective of the diameter of the wound tape, namely, regardless whether the wasted section is located close to the beginning (having smaller diameter) or the end of T-2 (having larger diameter). This invention provides a driving method which makes it easy to keep the disengaged condition of the capstan and the
