Abstract

PURPOSE:To prevent a line from being uneffectively held and to set a system to automatically answer to a call with considering a telephone function by providing a ringing detecting circuit, an automatic answering control circuit and a CML relay which switches the line on the side of a MODEM and the like. CONSTITUTION:If a ringing signal RNG is detected in the ringing detecting circuit 1 on a reception side, an automatic answer is not executed for a prescribed time optionally set from the detected time, and the signals RNG are kept receiving. Consequently, the bell of a telephone set 5 keeps on ringing in the meantime, and communication by the telephone set 5 is executed with picking up a handset. If the handset is not picked up on the receiving side, the facsimile equipment automatically answers in prescribed time through the automatic answering control circuit 3, the CM relay 4 and the MODEM2, and the system shifts to a facsimile communication. Thus, the line is provided from being uneffectively held and the system can automatically answer to the call with sufficiently considering the telephone function.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an automatic call answering system in a facsimile machine, and particularly when the line is not exclusively used for facsimile communication,
The present invention relates to an automatic call answering system suitable for a facsimile machine in which a facsimile machine and a telephone share one telephone line.

[Conventional technology]

Conventionally, as described in Japanese Patent Application Laid-open No. 59-175277, the telephone switching function is activated only when no signal is received from the caller after an automatic response. Since the call is automatically answered and then switched to a telephone call, the line is put on hold from the time of the answer to the time of the switch.

[Problem that the invention seeks to solve]

In the above-mentioned conventional technology, since the telephone is switched for the first time when no signal is received from the calling party after automatic answering, there is a problem in that the line is held invalidly. The caller is also subject to additional call charges for this line-invalid hold time. Furthermore, according to the prior art, the calling side cannot detect that the receiving side is switching over and making a telephone call, so the aspect of the telephone function is neglected.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic call answering system for a facsimile machine equipped with telephone equipment, which prevents lines from being held invalidly and which also fully takes telephone functions into account.

[Means for solving problems]

The purpose of the above is to make the telephone ring for a certain period of time that is arbitrarily set as variable, without immediately automatically answering when a ringing tone is detected, giving the operator at the receiving end time to pick up the handset. This is achieved by automatically answering the handset after the time has elapsed if the handset is not picked up within the time.

[For production]

A relatively large fixed period of time is variably set between the time of detection of the ringing tone and the time of automatic response. During this time, there is no automatic answering, and the line is connected to the telephone, so the ringing bell continues to ring, allowing the receiving operator to pick up the handset and answer the call. .

If the receiving party does not pick up the handset and does not respond to the call, an automatic response is performed for the first time after a certain period of time has elapsed. This allows the calling party to confirm the call to the other party by means of a ringback tone for a certain period of time. Furthermore, if the receiving party does not pick up the handset and does not answer, and the calling party takes down the telephone within a certain period of time, the line will be released before the receiving party automatically answers. When a call is automatically answered in this manner, the telephone function is fully taken into account and the invalid hold of the line is prevented.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

First, the facsimile apparatus according to the present invention will be explained. As shown in FIG. 2, the facsimile apparatus includes a ringing detection circuit 1.
CML relay 4 that switches modem 21 line to modem side
．． It is constructed to include an automatic response control circuit 3 that receives a ringing detection signal and turns on a CML relay 4 to perform an automatic response.

Now, to explain the operation with reference to Figure 1, when the ringing signal RNG is detected on the receiving side, no automatic response is performed for a certain arbitrarily set time (response time) from the time of detection. The ringing signal RNG continues to be received, so that the bell of the telephone 5 is kept ringing during this time. If the receiver picks up the handset during this time, the facsimile machine will not respond automatically and the receiver can talk to the sender as a telephone. Furthermore, if the receiver does not pick up the handset, the facsimile machine automatically responds after a certain period of time and sends out a CED signal, thereby entering into facsimile communication. When a call is made by telephone from the sending side, the call to the other party can be confirmed by the ringback tone RNGBT, and if the receiving side does not pick up the handset within a certain period of time, the line is released by taking down the handset. It is a place where you can learn.

〔Effect of the invention〕

As explained above, the present invention has the effect of automatically answering a call while fully considering the telephone function and preventing the line from being put on hold.
