Abstract

PURPOSE:To inform the call being an object of conversation to the operator by prolonging a detection time of a CI signal when the CI signal from a caller side is detected again within a prescribed time after line disconnection. CONSTITUTION:When a call is given from a telephone set being an object of conversation to a facsimile equipment in the automatic reception state, a timer 11 is cleared and when the CI signal is detected by a set count A, the reception operation is restored. Since no facsimile signal is sent from the opposite party, the error end is caused and the line is disconnected. Then an automatic reception fail flag is cleared, after the program timer 11 is set, a count B is set in a CI detection counter and the count B is a larger than the count A. When the CI is detected until the time of the programmable timer 11 is over, the CI signal is detected by the count B. Thus, since the operator of the called party recognizes the call being an object of conversation because the telephone ring time is longer than the usual case.

Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to an automatic reception method for a facsimile machine.

[Technical background of the invention and its problems] Conventionally, a facsimile machine having an automatic reception function receives a 16Hz paging signal (CI) from a calling party in an automatic reception state.
If a low signal was detected for a certain period of time, it would automatically enter reception mode.

For this reason, when a call is made for the purpose of conversation from a telephone that is not connected to the facsimile, and even if a low CI signal is received from this telephone number 1, the telephone enters the receiving operation, so there is a problem that normal conversation cannot be carried out.

In order to avoid this, in other words, to balance incoming facsimile calls and incoming conversation calls, set the facsimile machine to manual reception mode and have the operator control the incoming facsimile and conversation calls.
i! However, this method had the problem that the operator had to be near the facsimile at all times.

[Purpose of the Invention] The purpose of Kikomei is to solve the above-mentioned problems by providing a system that, when a call is made for the purpose of conversation in an automatic receiving state, can notify the operator that the call is for the purpose of conversation. The object of the present invention is to provide an automatic reception method for facsimile machines that allows normal conversation with an operator.

[Summary of the Invention 1 To achieve the above object, the present invention connects the line when a CI signal from the calling side is detected when automatic reception is set, and disconnects the line when a predetermined signal is not detected from the calling side. , if a CI signal from the calling side is detected again within a certain period of time after the line is disconnected, the detection time of CI No. 18 is lengthened.

[Embodiments of the invention] Examples of the present invention will be described in detail below.

FIG. 1 is a block diagram of the main parts of a facsimile device according to an embodiment of the present invention, and this facsimile device includes:
Network control unit <NCU> 1, frequency detection circuit 3, central processing unit (CPLJ) 5, read only memory (ROM> 7,
A random access memory (RAM) 9 and a programmable timer 11 are connected to the data bus 13, and the NCU 1
is connected to line 15 and telephone 1117. When the frequency detection circuit 3 detects the frequency of the signal input via the line 15 and NCU1, it transmits this to the CPU 5.

Next, the receiving operation of this facsimile machine will be explained according to the flowchart shown in FIG.

First, if the facsimile machine is in a standby state and is not detecting a CI (step 201>, the automatic reception failure flag is set (step 203>), and the programmable timer 11 is cleared (step 205), then the CP
U5 is counted in the CI detection counter! Step 207) to set liA, CI detection process]! LI (Step 2
09).

Next, the automatic reception state is also in C1 detection (step 201).
)'s facsimile machine for the purpose of conversation! i
When a call is made from I, the timer is cleared (step 211)'#t, CI detection processing JII! (Step 20
9), and when the count number A of CI signals set in step 209 is detected, the process moves to the reception operation. However, in this case, since no facsimile signal is sent from the other party, the process ends with an error, the automatic reception flag is set, and the line is disconnected.

In such cases, the caller often makes a call again, and when the caller makes a call again, the CI is not being detected (step 20).
1) Since the automatic reception failure flag is set (step 203), clear this automatic reception failure flag.Step 213) After setting the programmable timer 11 (step 215), set the count number B to the CI detection counter. Set (step 217). This count number [1lrJ is larger than 3G to the runt number.

Next, the process moves to CI detection processing (step 209), and if 01 is detected before the programmable timer 11 times up, the Ct signal is detected by the count number B.

At the time of this re-call, the programmable timer 11 is set, and if the 01 signal is detected again within this hit time, it is determined that the call is from the same party for the purpose of conversation, and the normal number of C1 detections is repeated. Set the number of times higher than that to make the phone ring more often than usual.

Thus, even in the automatic reception state, the operator on the called side can know that a call has been made for the purpose of conversation because the telephone rings for more time than usual.

Figure 4 shows C1 when a call is made for the purpose of conversation on a facsimile machine in automatic reception mode.
The flow of reception interrogation after detection is shown below.When a call is made from the other party and a CI signal is detected by the facsimile machine in automatic reception mode, the facsimile machine transmits a called terminal identification signal (8) to the calling party. CED> and digital identification signal (Dis>
However, since no signal is sent from the other party, the group 2 digital identification signal (GI2DIS) is sent out for a certain period of time, and after time-up, an error occurs and the cycle FA is disconnected.

[Effects of the Invention] As described above in detail, according to the present invention, even if the other party's facsimile machine is set to automatic reception, if the call is made twice, the receiving party can recognize that the call is for the purpose of conversation. ° Be able to know each other and have normal conversations.
