Abstract

PROBLEM TO BE SOLVED: To reduce unwanted communication time by performing confirmation while using a caller ID sent from a network before the transmission of calling signal. SOLUTION: A line state detection part 18 is connected to a line by a line switching part 16 in initial standby state, detects polarity inversion and detects a caller ID transmission request as a line state later. When the line state detection part 18 detects the ID, an ID reception control part 19 enables the reception of ID at an ID reception part 12 by controlling the line switching part 16 and when the ID is received, the line is released. At such a time, this ID is compared with an ID previously stored in an ID memory part 17 for discriminating coincidence and when they are coincident, automatic call incoming is permitted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a facsimile apparatus according to an embodiment of the present invention.

In the figure, in the embodiment of the present invention, I which receives an ID from the main controller 10 and a line (telephone line) is used.
A D reception unit 12, an ID comparison unit 13 that compares the received ID with an ID stored in the ID memory unit 17 in advance,
When the IDs match, the automatic incoming call control unit 1 is notified from the main control unit 10 of the automatic incoming call permission for facsimile communication.
1, a signal detection unit 15 that detects a calling signal from a line after automatic incoming call permission, a line switching unit 16, and a facsimile communication control unit 20 that performs facsimile communication control.

Further, the line state detecting unit 18 is connected to the line by the line switching unit 16 in the initial standby state,
The polarity inversion is detected, and then the ID reception terminal activation signal is detected from the line. The ID reception control unit 19 controls the line switching unit 16 to be in the ID reception state when the line state detection unit 18 detects the ID reception terminal signal, and at the same time, I
When the D reception unit 12 confirms the reception of the ID, it controls the line switching unit 16 to release the line. At this time, if the main control unit 10 permits the automatic incoming call control unit 11 to accept the automatic incoming call due to the matching of the IDs, the automatic facsimile reception is performed after the detection of the calling signal.

The operation unit 14 is connected to the main control unit 10 and gives instructions such as automatic reception setting, dial operation, and transmission operation.

FIG. 2 is a flow chart showing the operation of the facsimile apparatus of FIG. The operation of FIG. 2 is performed when the ID reception mode is set by the operation 14, and the ID is not received by the normal automatic reception. Before the operation shown in FIG. 2, the operator first sets the storage mode on the operation unit 14 and inputs the ID (for example, a telephone number) of the caller who permits the automatic incoming call from the dial button of the operation unit 14. The number of IDs is not particularly limited. The input ID is stored in the ID memory unit 17 by the main control unit 10. After the storage, the storage mode is released from the operation unit 14.

Next, the incoming operation in the ID receiving mode will be described. In the ID reception mode, the line switching unit 16 causes the ringing signal detection unit 15 and the line state detection unit 1 in the standby state.
The line is connected to 8.

First, the detection of the caller ID transmitted before the call signal from the network will be described. First, as a means of notifying the sender ID transmission from the network, the polarity of the line is reversed, and this device in the standby state detects the polarity reversal by the line status detection unit 18 (step 30 in FIG. 2), and then from the network. The ID reception terminal activation signal to be transmitted is in a waiting state for detection.
When the line state detection unit 18 detects an ID reception terminal activation signal continuously sent from the network within a fixed time (step 3
1), the line is closed, and the ID transmission request signal b is sent to notify the ID reception control unit 19, and the ID reception control unit 19 controls the line switching unit 16 to switch the line to the ID reception unit 12 (step 32). .

Subsequently, the ID reception control unit 19 instructs the ID reception unit 12 to enter the ID reception waiting state by the ID incoming instruction signal c. When the ID receiving unit 12 receives the ID transmitted from the network (step 33), it notifies the ID receiving control unit 19 of the completion of the ID reception, and the ID receiving control unit 19
Controls the line switching unit 16 to release the line (step 3
4), connect to the ringer detector 15 and the line state detector 18.

The ID receiving unit 12 notifies the detected ID to the ID comparing unit 13, and the ID comparing unit 13 compares the ID with the ID stored in advance in the ID memory unit 17 (step 35) to determine whether they match or not. The result is notified to the main control unit 10.

When the main control unit 10 is notified of the result of coincidence, it notifies the automatic incoming call control unit 11 of automatic incoming call permission (step 36).

When the automatic call control unit 11 is notified of the calling signal detection signal a from the calling signal detection unit 15 within a fixed time, it controls the line switching unit 16 to connect the line to the facsimile communication control unit 20, The main control unit 10 is notified of the automatic incoming call execution. The facsimile communication control unit 20 executes a facsimile procedure (step 37). When the facsimile reception is completed, the main control unit 10 notifies the automatic incoming call control unit 11 of the communication completion, and when the automatic incoming call control unit 11 is notified of the communication completion, it controls the line switching unit and calls the line signal detecting unit 15. And the line state detection unit 18.

Next, the operation when the comparison results of the ID comparison section 13 are inconsistent will be described. The main control unit notified of the result of the mismatch does not notify the automatic incoming call permission to the automatic incoming call control unit 11 (step 38). When the ringing signal detection unit 15 notifies the ringing signal detection signal a in that state, the automatic incoming call control unit 11 does not instruct the line switching unit to close the line, so that the receiving operation is not performed.

In FIG. 1, when normal automatic reception is performed, the line state detecting unit 18 and the ID receiving unit 12 for ID reception are not connected to the line. Further, the transmission operation is the same as the conventional facsimile communication.

[0020]

As described above, the facsimile apparatus according to the present invention has means for detecting the caller ID transmitted before the call signal from the network side, and before the call signal is detected and the line is closed. The caller ID is detected in, and compared with the caller ID stored in advance to determine whether or not to perform reception. Therefore, ID detection, comparison determination time, and
Since it is possible to reduce unnecessary communication time that does not result in facsimile reception, it is possible to effectively use the facsimile device.

The reason is that before the line is closed in the automatic incoming call by the detection of the calling signal, the service used by the network before sending the calling signal is used, and the caller ID is used.
This is because it has a means for detecting
