【Example】
Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
[0011]
FIG. 1 is a block diagram of a facsimile apparatus according to the present invention. Reference numeral 1 denotes a main control unit (CPU), which is connected to a public line 4 via a modem 2 and a line control unit 3. The main control unit 1 includes a reading unit 5 for reading a transmission original, a display unit 6 such as an LCD, a key operation unit 7 for operating transmission and reception, a ROM 8 storing a program, and communication management and an audio signal to be described later stored as digital information. A RAM 9 and a printing unit 10 are connected as recording means for performing the recording, and a speaker 12 is connected via a voice converter 11.
[0012]
In the above, when facsimile transmission is first performed, the main control unit 1 reads a transmission original by the reading unit 5 and transmits the facsimile information to the destination facsimile via the modem 2 and the line control unit 3 via the public line 4. At the time of automatic facsimile reception, if there is an incoming call via the line control unit 3 and the modem 2, after performing a protocol of a predetermined communication procedure with the facsimile of the transmission destination, the facsimile information is printed by the printing unit 10. .
[0013]
The main control unit 1 creates a communication management report indicating a communication destination ID, transmission / reception distinction, communication time, number of copies, a result, etc. for each one of the transmission and reception, stores the report in the RAM 9, and stores the report in a predetermined number of times. The communication management report is output from the printing unit 10 or displayed on the display unit 6 when the key operation unit 7 is operated or when the key operation unit 7 is operated.
[0014]
If an incorrect call is received while waiting for automatic reception instead of facsimile transmission / reception, the main control unit 1 detects the voice signal of the other party (called side) while performing the protocol of the communication procedure. The voice signal is converted into a digital signal and stored in the RAM 9, and the communication management report describes that the communication is present and the call is incorrect. Can be played.
[0015]
The flowchart of the present invention will be described with reference to FIGS.
[0016]
During the automatic reception standby 20, in step 1, the presence / absence of a call signal is detected. If there is a call signal (yes), the line is connected to the facsimile machine 21 and then the timer T for detecting a voice signal is set to 2 .6 seconds, and at the same time, set 40 seconds 22 in the timer T1 for releasing the line when communication is malfunctioning . Next, in step 2, it is determined whether there is a signal (voice) other than the communication procedure signal. If there is a voice signal (yes), the recording of the sound of the line is started 23 (no), and if there is no voice signal (no), it is determined in step 3 whether or not the timer T has elapsed for 2.6 seconds, and the time is up (yes). If there is, receiving the CNG signal from the calling station, sends out the called station identification signal (CED) 24, then sends out the digital identification signal (DIS) 25, and then sets the timer T to 3 seconds 26 In the meantime, if a digital command signal (DIS) is detected in the communication procedure, that is, the determination in step 4 (yes), the recording in step 2 is stopped, the recording is erased 27, the facsimile image reception recording 28 is performed, and the communication is performed. After performing the post-procedure 29, the line is released 30. If the digital command signal (DIS) is not detected in step 4 (no), it is determined in step 5 whether there is a signal (voice) other than the communication procedure. If it is (yes), recording in step 2 is performed. Then, the recording of the line sound is started 31 and it is determined in step 6 whether or not 3 seconds have elapsed by counting up the timer T. If 3 seconds have elapsed (yes), the T1 time (40 seconds) is determined in step 7 ) It is determined whether or not it has elapsed, and if 40 seconds have elapsed (yes), the recording is stopped 32 and then the line is opened 30.
[0017]
Next, after releasing the line 30, a communication management report is created. That is, as shown in FIG. 3A, in step 8, it is determined whether or not the current automatic reception has received an image. If the image reception has been performed (yes), the destination, date, and number of sheets are displayed in the communication management table. The result etc is stored 31. If the image is not received (no), it is determined in step 9 whether an audio signal has been recorded. If the audio signal has been recorded (yes), the date and time and the result are displayed in the communication management table as "Machigai". The storage 32 is set to "waiting for automatic reception 20".
[0018]
This communication management table is stored separately for transmission and reception, as shown in FIG. 3 (b). In this example, the reception order, destination, date and time, number of sheets, result, recording No. . Is stored and printed out by the print unit 10 as appropriate. The management table 35 is a one-byte character code such as an ASCII code. Incorrect telephone calls are displayed in katakana. At this time, since no communication protocol is used, the destination ID and the number of sheets are blank.
[0019]
Next, a case will be described where an incorrect call is confirmed from the communication management table during the standby for automatic reception in FIG. In a state where there is no call signal in step 1 (no), the process proceeds to the determination of step 10, and it is determined whether or not the communication management display request key has been input. If the request key has been input (yes), FIG. As shown, the No. of the communication management table for reception shown in FIG. The record number 36 of 1 is called up and displayed 37 on the display device. This display content is displayed as indicated by reference numeral 38 in FIG. Next, in step 10, when the next item is scrolled by a key operation, the No. 2 is displayed as indicated by reference numeral 39 in FIG. Since the display 39 of the communication content is a stub, the reproduction key is operated by the key operation of the step 10, and the judgment of the step 11 is performed, and the corresponding recording No. is determined. Is played 39. By this reproduction, it is possible to specify who made the wrong call.
[0020]
When the management table is scrolled, the record number is sequentially incremented in step 11 and moved to the last record, and then the process returns to the waiting state 20.
[0021]
【The invention's effect】
In short, according to the present invention, when an incoming call is received by facsimile automatic reception, the timer T1 for interrupting the communication procedure is set, and the voice signal is detected within the time from when the incoming call is received until the called identification signal is transmitted . Sometimes the sound of the line is recorded, and the recording is stopped when the time is up to open the line with the timer T1 when communication is malfunctioning. By storing the telephone in the communication management memory, facsimile communication management can be performed correctly, and the voice signal can be reproduced to identify the caller.
