Description

The present invention relates to a facsimile machine. (B) Conventional technology Recently, the spread of facsimile machines has been remarkable, but there is an automatic reception function as a feature of the facsimile machines.
Although it is very convenient, such as automatically receiving and recording even in an unattended state such as at night, unnecessary information has been transmitted because reception from an unspecified person is also possible. Even in the case of mischief communication, there is a problem that the received and recording paper is wasted and the facsimile machine cannot be used during that time, so that necessary information cannot be communicated. Therefore, as a method of solving this problem, reception recording is performed only when the telephone number registered in advance in the receiving facsimile apparatus is transmitted from the facsimile apparatus, and when the telephone number is not registered, the telephone line is disconnected and reception is rejected. The applicant of the present application filed a facsimile apparatus on August 26, 1987. Although it is possible to restrict reception from unspecified people by this, it is possible to unilaterally cut off the line and reject the reception, so the sender does not know why it can not communicate,
There is a possibility that new problems such as repeated transmission operations may occur. (C) Problems to be solved by the invention The present invention has been made to solve the above problems,
An object of the present invention is to provide a facsimile apparatus capable of notifying a transmitting side of a reason why communication cannot be performed. (D) Means for Solving the Problems The present invention relates to a dial memory in which telephone number data of a transmission destination is stored, a unit for detecting telephone number data of a transmission-side facsimile apparatus transmitted from a transmission side, A buffer memory for storing telephone number data, an automatic dial device for automatically dialing based on the telephone number data stored in the dial memory or the buffer memory, and a message data indicating the reason for rejection of reception. The message memory and the telephone number data in the buffer memory are detected as to whether or not they are stored in the dial memory.If they are stored, reception is performed.If they are not stored, reception is rejected. It is constituted by control means for controlling transmission of message data in the message memory. . (E) Operation Since the present invention is configured as described above, the reception record is performed only when the telephone number stored in the dial memory of the receiving-side facsimile apparatus is transmitted from the facsimile apparatus. Reception and mischief communication can be prevented. Also, when the line is disconnected and reception is rejected, the automatic dialing device dials the transmission side based on the telephone number data stored in the buffer memory and transmits the message data stored in the message memory, The reason for rejecting the reception can be notified to the transmission side. (F) Example Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a facsimile apparatus.

A display (11) displays data input from the keyboard (10), data processed by the control circuit (1), and the like, and includes a liquid crystal display or the like. A modem circuit (12) modulates a signal transmitted to the telephone line (L) and demodulates a signal from the telephone line (L), and is connected to the line switching circuit (13). Line switching circuit (13) is telephone line (L)
A relay circuit is provided for switching connection between the modem circuit (12) and the telephone (14), and the switching is controlled by the control circuit (1). The line switching circuit (13) has a built-in incoming call detection circuit that generates an incoming call detection signal by detecting an incoming call bell signal. An automatic dialing device (15) generates a dial signal based on telephone number data stored in a dial memory (6) or a buffer memory (8), and outputs a telephone line (L) via a line switching circuit (13). Make a dial call to. Next, the operation of the present invention having the above configuration will be described with reference to the flowcharts of FIGS. First, prior to using the facsimile apparatus, the telephone number data of the other party to be communicated with frequently is input together with the abbreviated number from the keyboard (10) and stored in the dial memory (6). In the standby state, the facsimile apparatus monitors which mode has been set in steps (S ₁ ), (S ₁₁ ) and (S ₁₆ ).
3) By detecting the incoming detection signal from the incoming detection circuit in
Step (S ₁₎ detecting the incoming call in the control circuit (1) is response signal (CED, as shown in FIG. 2 proceeds to step (S ₃₎
Performs transmission of signals), followed by checking the state of the reception mode switch keyboard (7) in step (S _4),
It is determined whether the reception is all reception or specific reception. Assuming that Tsu switching now full reception mode, receives recorded in step recording unit carries out reception processing advances to (S ₅₎ (4). TS However receive mode switch is in the case are Tsu switching to a particular reception mode, the control circuit (1) proceeds to step (S ₄₎ from Step (S _8), which has been transmitted from the transmission side
The transmission-side telephone number data contained in the I signal (transmitting station identification signal) is detected, and the telephone number data is stored in the buffer memory (8). Then performed whether the detected telephone number data detected in the step (S ₉₎ are stored in the dial memory (6) in the same manner as described above proceeds to step (S ₅₎ when stored Perform automatic reception.
